[0002] Gates are control facilities used to close and open water channels. They are an important part of water conservancy structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc.

[0003] Existing gate plates are typically cast iron metal plates. When used, they are moved into a channel, such as a canal or river, to block the flow. However, when the channel needs to be opened, the water carries impurities such as silt, sand, and aquatic plants through the gate plate, failing to filter out these impurities. Furthermore, some debris can adhere to the gate plate, making it difficult to clean. Therefore, we propose a hydraulic engineering gate plate with a filtering function. Summary of the Invention

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 A water conservancy project gate with a filtering function includes an inner gate plate 5 and an outer gate plate 14. The tops of the inner gate plate 5 and the outer gate plate 14 extend out of the water surface. Columns 20 are provided on both sides of the inner gate plate 5 and the outer gate plate 14. Guide plates 19 are installed on both sides of each column 20. The guide plates 19 are "L"-shaped structures, and the guide plates 19 and the sides of the columns 20 form a slide groove. Both sides of the inner gate plate 5 and the outer gate plate 14 are located in the corresponding slide groove. The inner gate plate 5 and the outer gate plate 14 can be limited by the slide groove, so that the inner gate plate 5 and the outer gate plate 14 remain stable.

[0025] It should be noted that both sides of the inner gate plate 5 and the outer gate plate 14 are sealed with the corresponding chute. In the actual process of blocking the water flow, the water will not leak out from both sides of the inner gate plate 5 and the outer gate plate 14.

[0026] like Figure 1 and Figure 3 As shown, a drainage groove 23 is provided in the middle of the outer gate plate 14, and a sieve plate 3 is installed in the drainage groove 23. In actual use, when the inner gate plate 5 is lifted, the water flow will flow through the sieve plate 3. During the flow, impurities in the water will be filtered out by the sieve plate 3.

[0027] like Figure 2 As shown, the tops of the two columns 20 are connected by a transverse plate 8, and the top of the transverse plate 8 is connected to the inner gate plate 5 through a lifting mechanism. The lifting mechanism includes a screw 11 rotatably connected to the bottom of the transverse plate 8. The top of the screw 11 is connected to the second drive motor 7, and the second drive motor 7 is fixed to the top of the transverse plate 8. The bottom of the screw 11 passes through the first connecting block 12 and is threadedly engaged with the first connecting block 12. The rotation of the screw 11 can be controlled by the second drive motor 7, and the position of the inner gate plate 5 can be adjusted.

[0028] like Figure 1As shown, a U-shaped frame 9 is installed at the bottom of the horizontal plate 8, and a wire pulley 10 is rotatably connected between the U-shaped frames 9. When the inner gate plate 5 and the outer gate plate 14 are lifted to the top, there is a gap between the wire pulley 10 and the top of the inner gate plate 5 and the outer gate plate 14. One end of the wire pulley 10 is connected to the output shaft of the first drive motor 6, and the first drive motor 6 is fixed on the side of the U-shaped frame 9. A connecting rope 13 is provided on the wire pulley 10, and the other end of the connecting rope 13 is fixed to the top of the outer gate plate 14. In actual use, when the sieve plate 3 needs to be cleaned, the wire pulley 10 can be driven to rotate by the first drive motor 6, and the wire pulley 10 will reel up the connecting rope 13, which can pull the outer gate plate 14 upward to move the sieve plate 3 out of the water for easy cleaning.

[0029] like Figure 1 and Figure 5 As shown, support blocks 22 are installed on the sides of the two guide plates 19 close to the outer gate plate 14, and a strip cleaning brush 4 is provided between the two support blocks 22. The side of the strip cleaning brush 4 is connected to the side of the sieve plate 3, and the strip cleaning brush 4 is located above the water surface. Second connecting blocks 15 are installed on both ends of the strip cleaning brush 4. The second connecting block 15 is fixed to the support blocks 22 by fastening bolts 21. In actual use, when the outer gate plate 14 rises, the strip cleaning brush 4 moves relative to the side of the sieve plate 3, so that impurities adhering to the sieve plate 3 can be cleaned, which is convenient for cleaning.

[0030] like Figure 3 As shown, support plates 2 are installed on both sides of the bottom of the outer gate plate 14, and a slag collecting trough 16 is provided on the top of the support plate 2. The slag collecting trough 16 is located below the sieve plate 3. The slag collecting trough 16 is a mesh structure. During actual use, the stains on the sieve plate 3 cleaned by the strip cleaning brush 4 will fall into the slag collecting trough 16 below under the action of gravity for collection.

[0031] Specifically, when the utility model is in use, when drainage is required, the staff controls the second drive motor 7 to work, and the second drive motor 7 drives the screw 11 to rotate. Under the action of the first connecting block 12, the inner gate plate 5 can be lifted up, and the water flow on one side of the inner gate plate 5 will flow through the opening between the inner gate plate 5 and the two columns 20. When the water flows, it will pass through the sieve plate 3 on the outer gate plate 14, and under the action of the sieve plate 3, the debris in the water can be filtered out. When the drainage is completed, the staff controls the second drive motor 7 again. Reversal, the inner gate plate 5 moves down to the preset position under the action of the screw 11. When there are too many impurities on the sieve plate 3, the staff controls the first drive motor 6 to work, and the first drive motor 6 drives the wire wheel 10 to rotate, and reels the connecting rope 13. The connecting rope 13 pulls the outer gate plate 14 upward, and the sieve plate 3 moves up with the outer gate plate 14. In the process of the sieve plate 3 moving upward, the strip cleaning brush 4 moves relative to the side of the sieve plate 3 to clean up the impurities adhering to the sieve plate 3. The cleaned impurities will fall into the slag collecting trough 16 under the action of gravity and be collected.

[0032] Furthermore, if Figure 3 As shown, second fixing blocks 17 are installed at both ends of the side of the slag collecting trough body 16, and first fixing blocks 1 are installed on the side of the support plate 2. The first fixing block 1 is fixed to the second fixing block 17, and the first fixing block 1 and the second fixing block 17 are fixed by bolts or locks. In this way, after collecting impurities on the screen plate 3, the staff can remove the slag collecting trough body 16 from the support plate 2, clean the impurities in the slag collecting trough body 16, and then install the slag collecting trough body 16 on the support plate 2.

[0033] Furthermore, if Figure 2 or Figure 4 As shown, a number of reinforcing rods 18 are provided between the two columns 20. Both ends of the reinforcing rods 18 are fixed on the side surfaces of the columns 20, and one side of the reinforcing rods 18 is connected to the side surface of the sieve plate 3. In this way, during the drainage process, the reinforcing rods 18 will be against one side of the sieve plate 3, and the impact of the water flow on the sieve plate 3 will not cause the sieve plate 3 to be deformed or damaged.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
