[0032] An installation and disassembly mechanism, which is fixedly arranged on the sealing mechanism, can facilitate the user to disassemble the protective shell cover 4 for subsequent maintenance;

[0033] One implementation of the first embodiment is as follows: the sealing mechanism comprises a positioning frame 5 fixedly connected to the top of the dam 1, a sealing ring 6 is fixedly connected to the inner wall of the positioning frame 5, a rubber ring 7 is fixedly connected to the surface of the sealing ring 6, the thickness of the rubber ring 7 is 8 mm, and the diameter is the same as the inner diameter of the protective shell 4;

[0034] In this embodiment, it is considered that the hoist 2 does not perform sealing treatment on the protective shell 4, and rainwater will still leak into the protective shell 4, causing corrosion damage to the hoist 2. Therefore, by setting a sealing mechanism, the protective shell 4 can be installed on the hoist 2 by aligning the position between the positioning block 12 and the card slot 22 to cover it. At the same time, the hoist 2 will just cover the surface of the sealing ring 6. At the same time, there is a rubber ring 7 between the protective shell 4 and the sealing ring 6, which is in close contact with the inner wall of the protective shell 4, effectively improving the sealing of the connection between the protective shell 4 and the sealing ring 6, and rainwater will not leak into the protective cover;

[0035] The problem that the protective shell cover 4 is not sealed by the gate hoist 2 and rainwater still leaks into the protective shell cover 4, causing corrosion damage to the gate hoist 2 is solved.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, this embodiment can avoid the problem of rainwater leakage by enhancing the sealing of the connection between the protective shell cover 4 and the sealing ring 6. However, in the prior art, the protective shell cover 4 is fixed by a screw, which is also prone to rust and thread slippage, which is not conducive to the subsequent opening of the protective shell cover 4 for maintenance. The installation and disassembly mechanism in this application includes two shells 8 fixedly connected to the top of the positioning frame 5, a spring 9 is arranged inside the shell 8, and moving blocks 10 are fixedly connected on both sides of the spring 9. A positioning rod 11 is fixedly connected to the side of the moving block 10 away from the spring 9, and one end of the positioning rod 11 passes through the outside of the shell 8. Two positioning blocks 12 are fixedly connected to both sides of the protective shell cover 4, and a positioning hole 13 used in conjunction with the positioning rod 11 is opened on one side of the positioning block 12;

[0038] The installation and disassembly mechanism also includes a push block 14 movably arranged on one side of the housing 8, a push rod 15 is fixedly connected to one side of the push block 14, one end of the push rod 15 passes through the interior of the housing 8 and is fixedly connected to a linkage block 16, a squeeze rod 17 is fixedly connected to the bottom of the linkage block 16, a squeeze block 18 is sleeved on the surface of the squeeze rod 17, and one side of the squeeze block 18 is fixedly connected to one side of the moving block 10;

[0039] In this embodiment, it is considered that the protective shell cover 4 is fixed by a screw in the prior art, which is also prone to rust and thread slippage, which is not conducive to the subsequent opening of the protective shell cover 4 for maintenance. Therefore, by setting an installation and disassembly mechanism, the two push blocks 14 can be pressed, and the push block 14 can drive the push rod 15, the linkage block 16 and the extrusion rod 17 to move. During the movement of the extrusion rod 17, its surface will squeeze the beveled edge of the inner wall of the extrusion groove 19, so that the extrusion block 18, the moving block 10 and the positioning rod 11 are close to the spring 9 along the trajectory of the sliding block 20 and the sliding groove 21. Move to one side, the positioning rod 11 will leave the inside of the positioning hole 13, and the protective shell cover 4 can be pulled up and removed to facilitate the maintenance of the gate hoist 2. After the maintenance is completed, the protective shell cover 4 is installed on the gate hoist 2 by aligning the position between the positioning block 12 and the slot 22 to cover it. At the same time, the gate hoist 2 will just cover the surface of the sealing ring 6, and then release the push block 14. The elastic force generated by the spring 9 will drive the moving block 10 and the positioning rod 11 to move, so that the positioning rod 11 enters the corresponding positioning hole 13, and the protective shell cover 4 is positioned.

[0040] Preferably, an extrusion groove 19 is provided on the top of the extrusion block 18, and the extrusion groove 19 is in a slope shape;

[0041] By setting the extrusion groove 19 in this embodiment, the extrusion groove 19 can be set to a slope shape. When the extrusion rod 17 moves its surface to be extruded to the beveled portion of the inner wall of the extrusion groove 19, the extrusion block 18, the moving block 10 and the positioning rod 11 can move along the trajectory of the sliding block 20 and the sliding groove 21 to the side close to the spring 9, thereby playing a transmission role.

[0042] Preferably, a sliding block 20 is fixedly connected to one side of the moving block 10, and a sliding groove 21 for use with the sliding block 20 is provided on the inner wall of the housing 8;

[0043] This embodiment can limit the moving track of structures such as the moving block 10 and the positioning rod 11 by setting the sliding block 20 and the sliding groove 21, so that they can only move along the track of the sliding block 20 and the sliding groove 21 during movement, and the movement is more stable.

[0044] Preferably, both sides of the housing 8 are provided with a card slot 22, and the card slot 22 is used in conjunction with the positioning block 12;

[0045] In this embodiment, by providing the card slot 22 , the card slot 22 can cooperate with the positioning block 12 to improve the stability of the protective shell cover 4 after installation and reduce the wear caused by shaking.

[0046] Working principle: the protective cover 4 can be installed on the gate hoist 2 to cover it by aligning the position between the positioning block 12 and the card slot 22. At the same time, the gate hoist 2 will just cover the surface of the sealing ring 6. At the same time, there is a rubber ring 7 between the protective cover 4 and the sealing ring 6, which is in close contact with the inner wall of the protective cover 4, effectively improving the sealing performance of the connection between the protective cover 4 and the sealing ring 6, and rainwater will not leak into the protective cover;

[0047] At the same time, by pressing the two pushing blocks 14, the pushing block 14 drives the pushing rod 15, the linkage block 16 and the squeezing rod 17 to move. During the movement of the squeezing rod 17, its surface will squeeze the beveled edge of the inner wall of the squeezing groove 19, so that the squeezing block 18, the moving block 10 and the positioning rod 11 move along the trajectory of the sliding block 20 and the sliding groove 21 to the side close to the spring 9, and the positioning rod 11 will leave the inside of the positioning hole 13. At this time, the protective shell cover 4 can be pulled up and removed to facilitate the maintenance of the gate opening and closing machine 2. After the maintenance is completed, the protective shell cover 4 is installed on the gate opening and closing machine 2 by aligning the position between the positioning block 12 and the card slot 22 to cover it. At the same time, the gate opening and closing machine 2 will just cover the surface of the sealing ring 6. Then release the pushing block 14, and the elastic force generated by the spring 9 will drive the moving block 10 and the positioning rod 11 to move, so that the positioning rod 11 enters the corresponding positioning hole 13 to complete the positioning of the protective shell cover 4.
