[0030] In view of the above problems, the embodiment of this application provides a water gate lifting device, which can ensure the smoothness of the gate lifting, avoid the situation that the water flow rate and water level cannot be accurately controlled due to jamming when the gate is lifted, and improve the use effect of the lifting device.

[0031] The technical solutions of the embodiments of this application will be described in detail below with reference to the drawings.

[0032] See Figure 1 、 2 、4, the water gate lifting device includes an installation frame 1. The inner side wall of the installation frame 1 is slidably connected with a gate 2 through a slide rail, and a driving and lifting assembly for driving and lifting the gate 2 is provided on the installation frame 1. A rod groove 3 is opened on the upper end surface of the gate 2, and the driving and lifting assembly is connected to the gate 2 through the rod groove 3. A lubrication structure 7 is provided on one side of the driving and lifting assembly.

[0033] The lubrication structure 7 includes a transparent oil storage box 71, an oil outlet pipe 72 and a switching valve 73. The transparent oil storage box 71 is connected to a box groove reserved and opened in the mounting frame 1. One end of the oil outlet pipe 72 is connected to the lower end surface of the transparent oil storage box 71, and the other end is located on the side of the part of the driving and lifting assembly in the rod groove 3. The switching valve 73 is arranged outside the oil outlet pipe 72. The lubrication structure 7 further includes an oil inlet pipe 74 and a plug 75. The oil inlet pipe 74 is connected to the upper end surface of the transparent oil storage box 71, and the plug 75 is clamped at the open end of the upper end surface of the oil inlet pipe 74.

[0034] During operation, first pull out the plug 75, inject lubricating oil into the transparent oil storage box 71 through the oil inlet pipe 74, and part of the lubricating oil can be stored on the lifting device. During subsequent maintenance operations, there is no need to carry lubricating oil. When a relatively large sound is generated during lifting, manually turn the switching valve 73 to open it. The lubricating oil drips onto the connection between the screw block 4 and the screw rod 5 through the oil outlet pipe 72, which can play a lubricating role, reduce the friction between the screw rod 5 and the screw block 4, ensure the smooth lifting of the gate 2, avoid the situation where the flow rate and water level of the water flow cannot be accurately controlled due to jamming during the lifting of the gate 2, and improve the use effect of the lifting device.

[0035] In some embodiments, referring to Figure 3 , 5 , a filter frame 8 is connected to the back surface of the mounting frame 1. A disassembly and assembly structure 9 is provided at the connection between the filter frame 8 and the mounting frame 1. The disassembly and assembly structure 9 includes a connection seat 91 and a clamping block 93. The connection seat 91 is fixedly connected to the outer wall of the mounting frame 1. A clamping groove 92 is formed on the surface of the connection seat 91. The clamping block 93 is inserted into the inside of the clamping groove 92, and one end of the clamping block 93 away from the clamping groove 92 is connected to the filter frame 8. The disassembly and assembly structure 9 further includes an inserting block 95, an inserting rod 97 and a spring 98. A groove 94 is formed in the inner wall of the connection seat 91 and at the upper end of the clamping groove 92. The inserting block 95 is arranged inside the groove 94. An inserting groove 96 is formed on the upper end surface of the clamping block 93. The inserting rod 97 is inserted into the inside of the groove 94, and its upper end penetrates through the top of the groove 94, and an inserting rod head is provided. The lower end of the inserting rod 97 is connected to the inserting block 95. The spring 98 is sleeved outside the inserting rod 97 and is located inside the groove 94, and the free end of the spring 98 is connected to the inserting block 95.

[0036] During operation, the filter box 8 can effectively intercept the garbage in the water flow when the gate is opened. First, the clamping block 93 outside the filter box 8 is inserted into the clamping groove 92 opened in the connecting seat 91. After being inserted in place, the inserting block 95 just fits into the inserting groove 96, which can quickly realize the installation of the filter box 8. Moreover, when cleaning the filter box 8, first manually pull up the end of the inserting rod 97, so that the spring 98 in the groove 94 is stressed and contracts, driving the inserting block 95 to move upward and out of the inserting groove 96. Finally, pull the filter box 8, and the clamping block 93 moves out of the clamping groove 92, and the filter box 8 can be quickly removed. This disassembly and assembly method is simple to operate, solves the problem that the existing use of bolts for fixing causes the threads to be easily slippery and stuck during screwing, resulting in insecure installation. In addition, it avoids the situation where it needs to be disassembled and reinstalled due to improper installation, and also prevents the disadvantage that the bolts are difficult to screw due to oxidation and rust caused by water vapor.

[0037] In some embodiments, referring to Figure 6 , the driving and lifting assembly includes a screw block 4, a screw rod 5 and a forward and reverse motor 6. The screw block 4 is connected to the inner wall of the rod groove 3. The forward and reverse motor 6 is installed on the upper end surface of the mounting frame 1. The screw rod 5 is connected to the output end of the forward and reverse motor 6. The screw rod 5 threadedly penetrates through the screw block 4. The lower end of the oil outlet pipe 72 is located at the connection between the screw block 4 and the screw rod 5. An outer cover 10 is connected to the upper end surface of the mounting frame 1, and the outer cover 10 covers the outside of the forward and reverse motor 6.

[0038] During operation, the forward and reverse motor 6 drives the screw rod 5 to rotate forward and backward. The screw rod 5 is in threaded cooperation with the screw block 4, and the lifting operation of the gate 2 can be realized. An outer cover 10 is connected to the upper end surface of the mounting frame 1, which plays a protective role for the forward and reverse motor 6. The outer cover 10 covers the outside of the forward and reverse motor 6.

[0039] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms including, containing or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
