The invention relates to agriculture and can be used in the production of vegetable, berry and mushroom products.

The closest to the proposed device is a device for growing plants in room conditions, containing a base on which a pallet for plants is placed, a screen on the one hand wound on a drive-coupled drum with a drive, and on the other hand connected with the load and separating the inner radiator from the external Environment.

This device allows the use of radiant energy of the environment to increase the efficiency of growing plants. However, unproductive energy consumption remains high due to a lack of regulation of the use of radiant energy of the environment taking into account the parameters inside the device, which can create unfavorable conditions for growing plants, for example, overheating and drying. The device provides an air-irrigation system for the internal space, but it significantly complicates the design and operation of the device in living quarters.

The purpose of the present invention is to increase the efficiency of the use of electric power and to improve the conditions for growing plants while simplifying the operation of the device by the consumer.

The essence of the invention consists in that a device for growing plants comprising a body with a base on which a pallet for plants is placed, a shield for covering the side wall, on the one hand wound on a drum with a drive of its rotation, and on the other hand connected with a load, installed in The internal radiators and the plant irrigation system are provided with internal and external illumination sensors, a control unit and sensors for the upper and lower position of the load to achieve the above objective, with at least one contact sensor for the upper and lower load positions on the side wall of the body , And the outputs of the light sensors are connected to the input of the control unit, one of whose outputs is connected to the radiators directly, and the other two through the sensors of the upper and lower position of the load connected to the corresponding inputs of the rotation drive.

In addition, the base can be made in the form of a frame of vertical racks and horizontal bars supporting the screen.

The screen can be made of a translucent film or foil.

The sensors for the upper and lower position of the load can be made in the form of limit switches.

In the walls of the hull, vertical guide grooves can be provided in which the ends of the load are formed in the form of a horizontal strip of metal, the drive of rotation of the drum is made in the form of an electric motor connected through a reducer with a drum, the limit switches are installed in the upper and lower ends of the guide grooves .

In addition, internal light controllers, two comparison elements, a threshold element, an emitter control unit can be input to the device, wherein the internal illumination detector is connected through the first comparison element to the radiator control unit, the inputs of the upper and lower load position sensors are connected through a series-connected threshold element And a second comparison element with the outputs of the external and internal illumination sensors, and the outputs are connected to the drum drive control unit, the output of the inner light sensor being connected to the free input of the first comparison element.

In the device can be introduced sensors intermediate position of the load.

In Fig. 1 shows a device, a general view;
FIG. 2 is a block diagram of power management of the device.

The device for growing plants consists of a base 1, on which there are a pallet 2 with vegetation vessels 3 fixed around the perimeter of the base wall 4 of the body (or frame frame), a cover 5 with an emitter 6, a container for nutrient solution 7, Vegetation vessels 3. On the outside of the cover 5, an ambient light sensor 12 is mounted and, on the inside of the cover 5, an electric motor 9 is connected to the radiator 6, which is connected to the drum 11 through the reducer 10, on which the screen 13 is wound, the free end of which is secured the load 14 In the form of a strip of metal whose ends enter the grooves of the guides 15 fixed to the side walls 4. At the top of the guides 15 there is an upper limit switch 16 and in the lower part of the guides 15 the lower limit switch 17. On the base (on the shell wall or frame stand ) In the area of ​​the pallet 2 for plants, an internal light sensor 18 is mounted, and an internal light sensor 19 and elements of a power consumption control block for the device are mounted on the cover.

The power management control block contains a comparison element 20 to which the internal light sensor 19 is connected to the first input, and the internal illumination sensor output 18 is connected to the second input, the output of the first comparison element 20 through the emitter control unit 21 is connected to the radiator 22. The ambient light sensor 12 is connected to the first input of the second comparison element 23, and the second output of the internal light sensor is connected to its second input. The output of the second comparison element through the threshold element 24 having two outputs is connected to the upper 16 and lower 17 limit switches connected to the motor control unit 25 connected to the motor 9.

The device works as follows. In the "night" mode, when the plants do not need light, the signal to the program input of the radiator control unit 21 is not applied and the latter switches off the radiation source 22. Simultaneously, a signal is sent to the motor control unit 25, which sets the screen 13 to the closed state via the electric drive.

In the "day" mode, a signal is sent to the program inputs of the illumination control unit 21 and the internal lightness meter 19. The signals from the internal light level sensor 19 and the ambient light sensor 18 are fed to the first comparison element 20 and if the illumination is less than the norm, the signal difference is fed to the control unit Emitter 21 which additionally includes a radiator 22. Simultaneously, signals from the inner light sensor 18 and from the ambient light sensor 12 are supplied to the second comparison element 23, and if the ambient light level is higher than the inside, then a signal greater than zero appears at the first output of the threshold element 24 , And at the second output the signal will be zero. The signal from the first output of the threshold element 24 through the normally closed upper limit switch 16 will go to the motor control unit 25 which, through the reduction gear 10, will rotate the drum 11, and the screen 13 will begin to rise. When the screen 13 opens completely in the vertical direction, the load 14 opens the upper limit switch 16, the motor control unit 25 de-energizes and the screen movement stops. If the illumination outside becomes less than the threshold illumination inside the greenhouse, a signal greater than one will appear at the second output of the second threshold element 24, zero at the first output and the motor 9 will turn on the normally closed limit switch 17 and the electric drive 25, which will start rotating the drum 11 in the other direction And the screen 13 begins to descend until the load 14 opens the lower limit switch 17, causing the engine 9 to de-energize and the motion of the screen 13 to cease. In this case, the light of the radiator 22 will be reflected from the screen surface inside the greenhouse.

Thus, the device makes it possible to use the radiant energy of the environment taking into account the parameters of the plant habitat inside the device, thereby reducing the energy consumption of the device and improving the growing conditions of the plants. In this case, the energy of the internal radiator is used to a greater extent by reducing the radiation into the external medium with less illumination from the outside than inside the device.
