[0002] The gate is a control facility used to close and open the discharge channel. It is an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. The hydraulic gate is an important control device in hydraulic projects and an important part of hydraulic structures. It can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. When the gate is opened to release water, the water will carry a large amount of floating objects, silt and other impurities. If these impurities enter the gate chamber and subsequent hydraulic facilities, they will cause wear and damage to the equipment, affecting the service life and operation efficiency of the equipment;

[0003] In the prior art, floating objects are usually handled by installing a fixed trash rack in front of the gate. However, the fixed trash rack may cause blockage after long-term use, so it requires regular maintenance by staff and cannot be automatically cleaned. It lacks applicability. Therefore, we urgently need to provide a lifting gate for water conservancy projects.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0014] 1. By installing two first rack plates on the surface of the gate body, when the gate is opened, the gate body drives the first rack plate to move upward. Under the action of the first rack plate, the movable rod and the linkage gear rotate.

Similarly, when the gate is closed, the gate body moves downward, causing the water filter screen to move upward in the opposite direction. Under the action of the scraper, the filter screen is automatically cleaned, so that the device can not only effectively intercept floating objects in the water, but also automatically clean the filter screen surface, greatly reducing the workload of maintenance personnel. At the same time, the lifting and lowering of the filter screen is synchronized with the gate, and will not affect the normal opening and closing of the gate;

[0015] 2. The driving motor drives the rotating shaft to rotate forward and reverse, and then drives the two winding rollers fixed on the surface of the rotating shaft to wind and unwind the lifting rope, so that the gate body is driven by the lifting rope to be raised and lowered, which greatly improves the convenience of gate lifting and lowering and reduces the labor intensity of manual operation.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a lifting gate for a water conservancy project, referring to Figure 1-Figure 4 , including a base 1, a gate body 2 is provided at the inner bottom of the base 1, first rack plates 9 are fixedly connected to the two ends of the front surface of the gate body 2, a movable rod 10 is rotatably installed at the inner middle part of the base 1, two linkage gears 11 are fixedly connected to the two ends of the surface of the movable rod 10, and the side parts of the two linkage gears 11 are meshed and connected to the first rack plate 9. By installing two first rack plates 9 on the surface of the gate body 2, when the gate is opened, the gate body 2 drives the first rack plate 9 to move upward, and under the action of the first rack plate 9, the movable rod 10 and the linkage gear 11 are rotated, and a water filter mesh plate 12 is provided at the inner upper end of the base 1, and two second rack plates 13 are fixedly connected to the two ends of the back of the water filter mesh plate 12, and the surfaces of the two second rack plates 13 are respectively meshed and connected to the other ends of the linkage gear 11 On one side, because the other end of the linkage gear 11 is engaged with the surface of the second rack plate 13 on the back of the water filter mesh plate 12, when the linkage gear 11 rotates, the water filter mesh plate 12 moves downward synchronously, thereby blocking floating objects and impurities in the water and improving the water discharge effect. A scraper 16 is fixedly installed on the upper end of the front surface of the base 1, and the inner end of the scraper 16 is in contact with the surface of the water filter mesh plate 12. Similarly, when closing the gate, the gate body 2 moves downward, causing the water filter mesh plate 12 to move upward in the opposite direction. Under the action of the scraper 16, the filter screen is automatically cleaned, so that the device can not only effectively intercept floating objects in the water, but also automatically clean the filter screen surface, greatly reducing the workload of maintenance personnel. At the same time, the lifting and lowering of the water filter mesh plate 12 is synchronized with the gate body 2, and will not affect the normal opening and closing of the gate.

[0023] Reference Figure 1 Figure 3The two ends of the inner side of the base 1 are respectively fixedly installed with a limit column 14 and a guide column 15. The two ends of the water filter screen 12 are movably connected to the surface of the limit column 14. The limit column 14 enhances the stability of the water filter screen 12 when it moves up and down. The two ends of the gate body 2 are movably connected to the surface of the guide column 15. The guide column 15 enhances the stability of the gate body 2 when it moves up and down. A discharge groove 17 is opened in the middle of the front surface of the base 1. The interior of the discharge groove 17 is set as an inclined surface and corresponds to the bottom of the scraper 16. The discharge groove 17 is provided to facilitate the discharge of impurities and sludge scraped by the scraper 16.

[0024] Reference Figure 1-Figure 2 A fixing plate 3 is fixedly installed at both ends of the top of the base 1, and a driving motor 4 is provided on the side of the fixing plate 3. The output end of the driving motor 4 passes through the fixing plate 3 and is connected to a rotating shaft 5. The end of the rotating shaft 5 away from the driving motor 4 is rotatably connected to the inner side of the fixing plate 3. Winding rollers 6 are fixedly installed at both ends of the surface of the rotating shaft 5. The surfaces of the winding rollers 6 are fixedly connected with hanging ropes 7. The driving motor 4 drives the rotating shaft 5 to rotate forward and reverse, and then drives the two winding rollers 6 fixed on the surface of the rotating shaft 5 to reel and unreel the hanging rope 7. Lifting ears 8 are fixedly installed on both sides of the upper end of the gate body 2, and the bottom end of the hanging rope 7 is fixedly arranged on the inner side of the hanging ear 8. The gate body 2 is driven by the hanging rope 7 to be raised and lowered, which greatly improves the convenience of gate lifting and lowering and reduces the labor intensity of manual operation.

[0025] The implementation principle of a lifting gate for a water conservancy project in the embodiment of the present application is as follows: when the device is used, the driving motor 4 is started to drive the rotating shaft 5 to rotate, thereby driving the two winding rollers 6 fixed on the surface of the rotating shaft 5 to wind up, so that the gate body 2 continues to rise, thereby opening the gate, and at the same time, under the action of the first rack plate 9, the movable rod 10 and the linkage gear 11 are rotated, and when the linkage gear 11 rotates, the water filter screen plate 12 moves downward synchronously, thereby blocking floating objects and impurities in the water. When closing the gate, the driving motor 4 drives the rotating shaft 5 to rotate in the opposite direction, thereby unwinding the suspension rope 7, and the gate body 2 moves downward under the factor of gravity. Under the action of the linkage gear 11, the water filter screen plate 12 rises synchronously, and when its surface passes through the scraper 16, the scraper 16 cleans its surface, and the scraped debris will fall into the inside of the discharge groove 17 for discharge, thereby realizing self-cleaning of the water filter screen plate 12.
