[0002] Hydropower refers to the science and technology of technical and economic issues such as engineering construction and production operation that converts water energy into electrical energy. The water energy used in hydropower is mainly the potential energy contained in the water body. In order to realize the conversion of water energy into electrical energy, different types of hydropower stations need to be built. In order to prevent blockage during the hydropower generation process, filtering devices are needed.

[0003] Existing hydropower generation water filtering devices usually use multi-layer filter elements to filter the sediment carried in the water. After long-term use, the sediment will clog the multi-layer filter elements, causing the water flow rate to slow down, reducing the water filtering efficiency and affecting the normal use of the filtering device. Therefore, the filter element needs to be disassembled and cleaned after a period of use. However, there is a lot of sediment in the water and the cleaning cycle is short. Frequent disassembly and cleaning increases the labor burden.

[0004] Therefore, a hydroelectric water filtering device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1 to 3 As shown, this embodiment provides a hydroelectric water filtering device, comprising:

[0028] Water inlet pipe 1;

[0029] The first filter part is connected to the water inlet pipe 1 at the top and the connecting pipe 2 at the bottom;

[0030] The second filter part includes a filter barrel 3, the top of the filter barrel 3 is connected to the connecting pipe 2, the outer cover of the filter barrel 3 is provided with a confluence barrel 4, and one side of the confluence barrel 4 is connected to a water outlet pipe 5;

[0031] The cleaning part includes an end cover 6, which passes through the bottom of the confluence barrel 4 and the filter barrel 3, and is detachably connected to the confluence barrel 4 and the filter barrel 3. The center of the end cover 6 is rotatably connected to a rotating shaft 7. One end of the rotating shaft 7 extends into the filter barrel 3 and is fixedly connected to a cleaning component, and the other end extends out of the end cover 6 and is fixedly connected to a rotating handle 8.

[0032] Water enters from the water inlet pipe 1, and is first filtered by the first filter part. The first filter part intercepts larger impurities such as leaves and branches that may be carried in the water, and the remaining small impurities such as mud and sand enter the connecting pipe 2 with the water flow, and enter the second filter part through the connecting pipe 2; first pass through the filter barrel 3 of the second filter part, the filter barrel 3 can intercept small impurities such as mud and sand in the water, the water filtered by the filter barrel 3 enters the confluence barrel 4, and finally flows out from the outlet pipe 5 on one side of the confluence barrel 4 to enter the hydropower generation device for power generation; there are fewer impurities in the water after double-layer filtration, which can avoid damage to the hydropower generation device and extend its life. Mud and sand are easy to adhere to the inner wall of the filter barrel 3. After a period of time, it can be simply cleaned by the cleaning part. When cleaning, turn the rotating handle 8, the rotating handle 8 drives the rotating shaft 7, and the rotating shaft 7 drives the cleaning component to rotate in the filter barrel 3, which can remove the mud and sand attached to the inner wall of the filter barrel 3 from the inner wall, maintain the filtering effect of the filter barrel 3, reduce the number of disassembly and cleaning, and save manpower.

[0033] To further optimize the solution, the cleaning component includes a fixed frame 9, the bottom center of the fixed frame 9 is fixedly connected to the top of the rotating shaft 7, and cleaning brushes 10 are fixedly connected to both sides of the fixed frame 9, and the cleaning brushes 10 are in contact with the inner wall of the filter barrel 3.

[0034] The rotating handle 8 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the fixed frame 9 to rotate. The cleaning brushes 10 on both sides of the fixed frame 9 rotate along the inner wall of the filter barrel 3 to scrape and clean the impurities attached to the inner wall of the filter barrel 3, thereby avoiding clogging of the filter barrel 3 and reducing the number of times the filter barrel 3 is disassembled and cleaned.

[0035] A further optimized solution is that the first filter part includes a first filter screen 11, which is fixedly connected to the top of the connecting pipe 2. The first filter screen 11 is conical, and the conical top faces the direction of water entering. The outer side of the first filter screen 11 is smoothly connected to a receiving platform 12, and the receiving platform 12 is fixedly connected to the outer wall of the connecting pipe 2. A receiving cavity 13 is fixedly connected to the bottom of the water inlet pipe 1, and the receiving cavity 13 is correspondingly arranged with the receiving platform 12 and is detachably connected.

[0036] When water flows through the first filter 11, larger impurities are intercepted. Since the first filter 11 is conical, the intercepted impurities will be washed around and stay on the receiving platform 12, which can prevent impurities from accumulating on the first filter 11 and affecting the flow of water. The receiving cavity 13 provides space for the accumulation of large impurities, so that the first filter part can store more impurities and reduce the frequency of cleaning the first filter part.

[0037] According to a further optimized solution, first connecting flanges 14 are fixedly connected to the outer side of the bottom of the storage cavity 13 and the outer side of the top of the storage platform 12 , and the two first connecting flanges 14 are connected by bolts 15 .

[0038] The two first connecting flanges 14 are detachably connected by bolts 15 , so as to facilitate cleaning of impurities accumulated on the support platform 12 .

[0039] According to a further optimized solution, a second connecting flange 16 is fixedly connected to the outer side of the end cover 6 , the second connecting flange 16 abuts against the bottom surface of the confluence barrel 4 , and is detachably connected to the bottom surface of the confluence barrel 4 via screws 17 .

[0040] The end cover 6 is connected to the manifold barrel 4 by screws 17 via the second connecting flange 16, so that it is easy to disassemble. The end cover 6 together with the cleaning assembly can be conveniently disassembled for cleaning.

[0041] According to a further optimized solution, a sealing gasket 18 is provided between the second connecting flange 16 and the bottom surface of the manifold 4 and between the two first connecting flanges 14 .

[0042] The sealing gasket 18 is convenient for sealing each connection to prevent water leakage.

[0043] According to a further optimized solution, the rotating shaft 7 and the end cover 6 are rotatably connected via a sealed bearing 19 .

[0044] The sealed bearing 19 can ensure the sealing performance while ensuring the rotation effect.

[0045] According to a further optimized solution, a plurality of support legs 20 are fixedly connected to the bottom of the confluence barrel 4 in a circumferential direction.

[0046] The support legs 20 raise the manifold barrel 4 to provide space for the installation and use of the rotating handle 8 .
