Detailed Description of the Embodiment

[0022] The following is a further detailed description of the present utility model in conjunction with the attached Figure 1 - attached Figure 2 drawings.

[0023] An embodiment of the utility model discloses a small - scale hydro - power generation device. In mountainous areas, the kinetic energy of mountain stream water can be converted into electric energy to achieve the purpose of power generation. Specifically, the device can be placed below the water - falling point of the stream to catch the falling stream water. Refer to Figure 1 and Figure 2 , the small - scale hydro - power generation device includes a support frame 1, on which a high - level water tank 2, a power generation mechanism 3 and a low - level water tank 4 are sequentially installed from top to bottom.

[0024] Refer to Figure 1 and Figure 2 , the high - level water tank 2 includes a box body one 20. A drain pipe one 21 is installed at the bottom of the box body one 20, and a valve one 210 is installed on the drain pipe one 21; the top of the box body one 20 is open and hinged with a top filter plate 22. The top filter plate 22 is used to filter the falling water flow, blocking stones, leaves, weeds and other objects outside to prevent these sundries from entering the box body one 20.

[0025] Refer to Figure 1 and Figure 2 , on the side wall of the box body one 20, there are support legs 23 for supporting the top filter plate 22 in an inclined state. The support legs 23 include sleeves 230. One end of the sleeve 230 is hinged to the side wall of the box body one 20, and an adjusting rod 231 is slidably inserted into the other end of the sleeve 230. A plurality of holes are arranged along the length direction of the adjusting rod 231, and holes are arranged on the sleeve 230. A pin 232 can be inserted when the holes on the sleeve 230 correspond to the holes on the adjusting rod 231, so as to fix the length of the support leg 23 and maintain the inclination angle of the top filter plate 22. Workers can adjust the inclination angle of the top filter plate 22 according to the flow direction of the stream. At the same time, the inclined top filter plate 22 is also convenient for sundries to slide off.

[0026] Refer to Figure 1 and Figure 2 , the power generation mechanism 3 includes a water turbine 30. The top of the water turbine 30 is connected to the drain pipe one 21. The water turbine 30 is connected with a generator 31, the generator 31 is connected with an AC - DC converter 32, and the AC - DC converter 32 is connected with a storage battery 33, so as to convert the kinetic energy of the water flow into electric energy for storage and supply for production and living use.

[0027] Refer to Figure 1 and Figure 2 , the low - level water tank 4 includes a box body two 40. The top of the box body two 40 is connected with a drain pipe two 41, and the top end of the drain pipe two 41 is connected to the water turbine 30; a diversion pipe one 42 and a diversion pipe two 43 are installed at a position close to the bottom plate on the side wall of the box body two 40. A valve two 420 is installed on the diversion pipe one 42. The diversion pipe one 42 is used to discharge water to the outside to avoid affecting the natural environment.
