[0034] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme of the present application will be further explained in combination with specific embodiments.

[0035] In combination Figures 1 to 7As shown, the embodiment is a water conservancy gate lifting device, which comprises a gate frame 1, a first lifting assembly, a blocking assembly 4 and a second lifting assembly. The blocking assembly 4 comprises an outer frame 41 and a water baffle 42. The first lifting assembly is installed on the top of the gate frame 1, and the output end of the first lifting assembly is connected with a gate plate 2. The first lifting assembly can drive the gate plate 2 to move up and down along the vertical direction. The outer frame 41 is sleeved outside the gate plate 2, and the two sides of the outer frame 41 are slidably connected with the gate frame 1. The water baffle 42 is arranged in the outer frame 41 and located on the water side of the gate plate 2. The water baffle 42 is connected with the gate plate 2 through a connecting plate 44. The water baffle 42 can prevent the water on the water side of the gate plate 2 from directly contacting the gate plate 2. The second lifting assembly is installed on the gate frame 1 and is used to drive the outer frame 41 to move up and down along the vertical direction.

[0036] In some embodiments, as Figure 1 With Figure 2 As shown, the first lifting assembly comprises a connecting end block 3, a connecting rope 5, a fixed plate 7, a connecting rod 8, a winding roller 9 and a first reversible motor 10. A pair of fixed plates 7 are symmetrically arranged on the top of the gate frame 1. The connecting rod 8 is rotatably connected between the fixed plates 7. A pair of winding rollers 9 are sleeved on the connecting rod 8. The first reversible motor 10 is installed on the side wall of any fixed plate 7, and the output end of the first reversible motor 10 is connected with the end of the connecting rod 8. A pair of connecting end blocks 3 are arranged on the top of the gate plate 2, and the connecting end blocks 3 correspond to the positions of the winding rollers 9. The connecting rope 5 is wound around the winding rollers 9, and the winding rollers 9 and the connecting end blocks 3 are connected through the connecting rope 5.

[0037] The first reversible motor 10 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the winding roller 9 to rotate in reverse, so that the connecting rope 5 is retracted or released. The connecting rope 5 drives the gate plate 2 to move up and down, thereby realizing the opening and closing of the gate plate 2. At the same time, the water baffle 42 can isolate the water from the gate plate 2, avoiding direct contact between the water and the gate plate 2, preventing the gate plate 2 from being lifted by the water pressure, and preventing the driving part of the first lifting assembly from running at high speed. The smoothness of the driving part during rotation is ensured, the high temperature of some structures caused by high-speed rotation is avoided, and the safe operation of the device is ensured.

[0038] In some embodiments, as Figure 3 With Figure 4As shown, the second lifting assembly comprises a protective cover, a driving gear 415, a driven gear 414, a lead screw 412, a threaded sliding block 413, a moving block 417 and a second reversible motor 416. A block groove 411 is arranged axially in one side lateral support of the gate frame 1, a moving groove 418 is arranged axially in the other side lateral support of the gate frame 1, the lead screw 412 is rotatably arranged in the block groove 411, the top end of the lead screw 412 is fixedly connected with the driven gear 414 which is installed on the top of the gate frame 1, the driven gear 414 is meshingly connected with the driving gear 415, the driving gear 415 is connected with the output end of the second reversible motor 416, the driving gear 415, the driven gear 414 and the second reversible motor 416 are externally provided with the protective cover. The threaded sliding block 413 is threadedly connected with the lead screw 412, the moving block 417 is slidably connected in the moving groove 418, one side of the outer frame 41 is connected with the threaded sliding block 413, and the other side of the outer frame 41 is connected with the moving block 417.

[0039] The driving gear 415 is driven by the second reversible motor 416 to rotate, and the driven gear 414 drives the lead screw 412 to rotate with the driving gear 415 due to the mutual meshing of the driving gear 415 and the driven gear 414, so that the threaded sliding block 413 moves in the block groove 411, and the moving block 417 moves in the moving groove 418, and the outer frame 41 can be pulled up by the cooperation of the threaded sliding block 413 and the moving block 417, thereby facilitating the cleaning operation of the outer frame 41.

[0040] In some embodiments, the gate frame 1 is provided with a water pumping assembly for pumping out the residual water between the water baffle 42 and the gate plate 2, so as to form a water-tight cavity between the water baffle 42 and the gate plate 2. Specifically, as shown, Figure 5 The water pumping assembly comprises a water pumping pipe 11, a fixed seat and an external water pumping device, the fixed seat is externally sleeved on the water pumping pipe 11, the water pumping pipe 11 is installed on the top outer wall of the gate frame 1 through the fixed seat, the connecting end of the water pumping pipe 11 is connected with the external water pumping device, and the water pumping end of the water pumping pipe 11 penetrates through the outer frame 41 and extends to the space between the water baffle 42 and the gate plate 2.

[0041] Further, the bottom of the gate plate 2 is fixedly connected with a first sealing strip 12, and the bottom of the water baffle 42 is fixedly connected with a second sealing strip 13.

[0042] When the gate plate 2 is lowered for isolation, some water will remain between the floating plate and the gate plate 2. At this time, the connecting end of the water suction pipe 11 is connected with an external water suction device, which can be a water suction pump. By operating the external water suction device, the water between the floating plate and the gate plate 2 is sucked out through the water suction pipe 11, ensuring that the cavity between the floating plate and the gate plate 2 is in a water-tight sealed state, avoiding the water in the cavity affecting the subsequent lifting of the gate plate 2 due to water pressure. In addition, the first sealing strip 12 and the second sealing strip 13 can enhance the sealing performance of the floating plate and the gate plate 2 when connected to the outer frame 41, preventing water from flowing into the cavity between the floating plate and the gate plate 2 from the gap between the connections.

[0043] In some embodiments, the water baffle 42 is a floating plate that is inserted into the inner part of the outer frame 41. The floating plate can provide at least part of the lifting force during the lifting of the gate plate 2.

[0044] The floating plate and the gate plate 2 are connected by the connecting horizontal plate 44. When discharging water from the upstream river, the floating plate can rise with the gate plate 2, and due to the buoyancy of the floating plate, the gate plate 2 has an upward lifting force during the lifting process, thereby assisting the lifting of the gate plate 2 and enhancing the smoothness of the lifting.

[0045] In some embodiments, as shown in Figure 6 The outer frame 41 is detachably connected to the filter plate 43 through the connecting structure 6. The filter plate 43 is located on the water-facing side of the gate plate 2. The connecting structure 6 can facilitate the disassembly and assembly of the filter plate 43 and the outer frame 41. The filter plate 43 can filter the garbage in the water to prevent the garbage from flowing into the downstream with the water.

[0046] Further, as shown in Figure 7 The connecting structure 6 includes an insertion block 61, a fixed frame 63, an embedded block 65, a threaded rod 64, and a handle 67. The outer wall of the filter plate 43 is symmetrically provided with an insertion block 61 and a clamping groove. The side wall of the outer frame 41 is provided with an insertion groove 62 that can be correspondingly inserted and matched with the insertion block 61. The insertion block 61 is provided with an embedded groove 66. The outer frame 41 is connected with a fixed frame 63 corresponding to the insertion groove 62. The top of the fixed frame 63 is provided with a threaded rod 64. The end of the threaded rod 64 located in the fixed frame 63 is connected with an embedded block 65 through a bearing. The end of the threaded rod 64 located outside the fixed frame 63 is connected with a handle 67. The handle 67 is provided with a T-shaped slot. The embedded block 65 and the embedded groove 66 can be inserted and matched.

[0047] When the filter plate 43 is worn, first take a flat tool and insert one end into the flat groove of the handle 67, then rotate the flat tool to drive the threaded rod 64 to rotate, so that the block 65 moves upward until it is removed from the embedded groove 66 into the inside of the fixed frame 63, and then manually pull the filter plate 43 to remove the plug 61 from the plug groove 62. The operation can separately remove the worn filter plate 43, and the above operation can replace the new filter plate 43, so that the entire blocking assembly 4 does not need to be replaced, avoiding waste of other parts of the blocking assembly 4, reducing the replacement difficulty, and also ensuring the blocking effect of the device on the garbage, avoiding the situation that the garbage follows the water flow through the gate and moves into the downstream, causing pollution to the downstream.

[0048] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
