[0019] The present utility model will be further described below in conjunction with the accompanying drawings.

[0020] According to Figures 1-4 As shown: The present utility model provides a water diversion structure for water conservancy and hydropower projects, including a support frame 2, on which a filter box 3 is fixedly connected; one side of the filter box 3 is connected with a water inlet pipe 1, and the other side of the filter box 3 is connected with a water outlet pipe 4; a filter frame 5 is vertically slidably arranged in the filter box 3, and two filter nets 6 are arranged in the filter frame 5; one of the filter nets 6 is located inside the filter box 3, and the other filter net 6 is located outside the filter box 3; an installation groove 8 is formed on the filter frame 5, and the filter net 6 is located in the installation groove 8; a clamping groove 9 is formed in the filter frame 5, and a clamping block 11 fixedly connected with the filter net 6 is arranged in the clamping groove 9; a jack 12 is formed on the clamping block 11, and an elastic plugging component inserted into the jack 12 is arranged in the filter frame 5.

[0021] By setting the slidable filter frame 5 and arranging two filter nets 6 on the filter frame 5, the replacement of the filter net 6 can be quickly completed without completely disassembling the filter structure, without delaying the water diversion process; at the same time, by setting the elastic plugging component, the replaced filter net 6 can be quickly disassembled and cleaned.

[0022] As Figure 4 、 5 shown, the elastic plugging component includes a plug rod 10, a compression spring 14, and a fixing plate 15; a spring groove 13 is formed in the filter frame 5, the plug rod 10 is located in the spring groove 13, and the plug rod 10 is inserted into the jack 12; the fixing plate 15 is located in the spring groove 13, and the fixing plate 15 is fixedly sleeved on the plug rod 10; the compression spring 14 is located at a position corresponding to the fixing plate 15, and the compression spring 14 is sleeved on the plug rod 10.

[0023] The installation groove 8 is formed on the side corresponding to the water inlet pipe 1. During the water diversion work, the action of the water flow can push the filter net 6 to be more stable in the installation groove 8; the compression spring 14 has a reserved compression amount, which can continuously generate pressure on the fixing plate 15, thereby increasing the fixing stability of the filter net 6.

[0024] As Figures 1-3 shown, three sealing plates 7 are fixedly connected to the filter frame 5, two of the sealing plates 7 are respectively located outside the filter box 3, and the other sealing plate 7 is located inside the filter box 3. The two sealing plates 7 outside the filter box 3 are fixedly connected to both ends of the filter frame 5, and the sealing plate 7 inside the filter box 3 is fixedly arranged in the middle of the filter frame 5.

[0025] Sealing gaskets are arranged at the positions where the sealing plates 7 contact the filter box 3, which can increase the sealing performance between the filter frame 5 and the filter box 3; and the sealing plates 7 located outside the filter box 3 are fixedly connected to the filter box 3 by screws, which is convenient for disassembly.

[0026] Principle of the utility model

[0027] like Figures 1-3 As shown, when the water diversion structure of the water conservancy and hydropower project is working, water enters the filter box 3 from the water inlet pipe 1, is filtered by the filter screen 6 in the filter box 3, and finally enters the water outlet pipe 4, thereby achieving the effect of water diversion.

[0028] When the filter screen 6 needs to be cleaned, ensure that there is no water in the filter box 3. Figure 3 In the state shown, the screws are removed, and the filter frame 5 is slid downward, so that the filter screen 6 to be cleaned originally located in the filter box 3 slides downward out of the filter box 3, and the clean filter screen 6 originally located outside the filter box 3 slides downward into the filter box 3, and the replacement of the filter screen 6 is quickly completed. The filter frame 5 is fixed and sealed again with the sealing plate 7, and then the water diversion structure can be immediately restarted, and the replaced filter screen 6 can be cleaned, which is not easy to delay the water diversion process. Figure 4 , 5 As shown, the insertion rod 10 is pulled to disengage the insertion rod 10 from the insertion hole 12 in the block 11, and at the same time, the fixing plate 15 compresses the compression spring 14, so that the filter screen 6 inserted into the installation groove 8 can be quickly taken out for easy cleaning; after cleaning, the insertion rod 10 is still pulled to insert the filter screen 6 into the installation groove 8, and then the insertion rod 10 is released. Under the action of the rebound force of the compression spring 14, the insertion rod 10 is inserted into the insertion hole 12, thereby completing the installation of the filter screen 6, which is quick and convenient.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
