INVENTION
Russian Federation Patent RU2241092
DAM Hydro power plants
Name of the inventor: Shestakov Frenkel (RU); Bagautdinov IN (RU); Pozdeev AG (RU); Lipchak SV (RU)
The name of the patentee: Mari State Technical University
Address for correspondence: 424024, Yoshkar-Ola, pl. Lenin, 3, MarSTU, Intellectual Property Department
Starting date of the patent: 2003.01.13
The invention relates to a small hydroelectric plants and can be used in forestry and agriculture or for personal use in remote areas. Hydroelectric includes plate upstream obliquely recessed at 1/3 depth removably topsheet watercourse energy and raising said layer to a certain height, at least one turbine placed at the base of a vertical cavity having a funnel-shaped entrance. Between the plate and obliquely recessed vertical cavity entrance funnel mounted hydraulic ram input coupled to the upper end of the recessed inclined plate feed pipe installed obliquely to the side hydraulic ram and provided with a funnel on the input side end plate. The output of the hydraulic ram is connected to a vertical cavity pressure pipe. The turbine may be mounted on a vertical axis. Cascade on the horizontal axis turbines could be installed at the base of the vertical cavity. The invention increases the reliability and capacity of hydroelectric power, increases the economic effect of its use.
DESCRIPTION OF THE INVENTION
The invention relates to a hydroelectric power small devices, in particular to hydroelectric power, and can be used in the timber industry, forestry, agriculture and other farms, and for individual use in remote areas.
Known DAM hydroelectric power plant, comprising a water turbine, water inlet and a flexible pressure hose, put on the slope of the river valley (small hydro. L.P.Mihaylov, B.N.Feldman, T.K.Markanova et al. / Ed. LP Mikhailov -. M .: Energoatomisdat -.. 1989, 184, see p.141, line 9 ... 19 top)..
The disadvantage of this damless hydroelectric power plant is that the water pressure is created virtually only slope of the river valley, so the capacity of hydroelectric power plants, as a rule, small.
DAM known hydroelectric plant comprising plate recessed slantingly upstream 1/3 depth removably upper energy, high potential of the watercourse bed, raising the layer to a certain height and its direction vertical to the funnel-shaped mouth of the cavity, a turbine disposed in the bottom of a vertical cavity on the vertical axis (AF Shirinsky new hardware adaptation of the energy systems to the natural conditions J. Hydraulic engineering -.. 1993, №11, see p.3, right column, 20 ... 27 top of the line.).
A disadvantage of the known hydroelectric damless is that the operation of the turbine depends on the height of the raised and watercourse layer by obliquely recessed plate, usually, the potential energy of the watercourse is not large, the turbine is placed on a vertical axis.
To eliminate these shortcomings DAM hydroelectric plant comprising plate recessed obliquely toward the stream at 1/3 depth removably topsheet watercourse energy, raising the layer to a certain height, and at least one turbine placed at the base of the vertical plane, having a funnel-shaped entrance, the new is the fact that between the inclined recessed plate and the funnel-shaped entrance vertical cavity mounted hydraulic ram, whose input is connected to the upper end of the inclined recessed plate feed pipe installed obliquely toward the hydraulic ram and equipped with a funnel-shaped entrance at the end of the part of the plate, and the output of the hydraulic ram is connected to a vertical pressure pipe cavity, and the turbine can be mounted on a vertical or horizontal axis.
This decision damless hydroelectric power station can increase its capacity for the same power consumption of the water flow.
The patent and scientific literature of similar design damless hydroelectric power we have not found.
The drawing shows a diagram of the device damless hydroelectric.
Damless hydroelectric includes obliquely recessed plate 1, which is set to meet the watercourse 2 and recessed about 1/3. On the upper end of the recessed inclined plate 1 is connected to the feed pipe 3 is mounted obliquely and the lower end is connected to the input of the hydraulic ram 4, in which the upper end of the funnel-shaped entrance 5. With input 6 set hydraulic ram 4 is connected to the pressure conduit 7. The upper end of the discharge pipe 7 is connected funnel inlet 8 vertical cavity 9 whose base is located on the vertical axis turbine or turbine stage on the horizontal axis (not shown).
Damless hydroelectric works as follows. Pan recessed plate 1 installed to meet the watercourse 2, removed energy of the upper, high-grade layer of the watercourse 10 2. This energy raises the layer 10 watercourse 2 to a certain height and directs the funnel-shaped entrance to the 5 inlet pipe 3, which directs the layer 10 to the input of the hydraulic ram 4. From the hydraulic ram 4 the inclined conduit portion 7 a layer 10 rises to a greater height than the plate 1 and forwarded to the funnel-shaped entry 8 vertical cavity 9 whose base is placed on a vertical axis turbine or turbine stage on the horizontal axis.
This device allows you to lift damless hydroelectric energy intensive layer watercourse to a considerable height by a hydraulic ram and install more than one turbine, and a cascade of generators and turbines to make better use of the energy of falling water.
CLAIM
1. damless hydroelectric comprising a plate upstream obliquely recessed at 1/3 depth removably topsheet watercourse energy and raising said layer to a certain height, at least one turbine placed at the base of a vertical cavity having a funnel-shaped entrance, wherein that between the obliquely recessed plate and the funnel-shaped entrance vertical cavity mounted hydraulic ram having an input coupled to the upper end obliquely recessed plate feed pipe installed obliquely to the side hydraulic ram and provided with a funnel-shaped inlet at the end side of the plate, and the output of the hydraulic ram is connected to the vertical cavity pressure pipe.
2. Hydroelectric according to claim 1, characterized in that the turbine is mounted on a vertical axis.
Hydroelectric power plant according to claim 1 3, characterized in that the base of vertical cavity turbine stage mounted on horizontal axes.
