According to user requirements, copper or stainless steel water stop can be used. Double-hanging-point cast iron gates have two hanging points on the top. In order to ensure the smooth opening and closing of the gate, the double hanging points must be synchronized, and a double-hanging-point hoist is required. A hydraulic hoist is required during the use of double-hanging-point gates.

The sealing plate 7 and the sealing ring 8 are provided to increase the sealing inside the protective shell, further improving the protective effect of the protective mechanism, so that the connecting piece 26 is covered inside the protective box 6 and will not be corroded by rainwater, effectively extending the service life of the connecting piece 26 and the hydraulic gate hoist 1;

[0034] The problem that the existing hydraulic gate hoist 1 does not have the function of protecting the connection of the gate 4, the screws are exposed to the air for a long time, and the screws will be corroded by rain in bad weather, causing the screws to rust and strip, which not only affects their service life but also poses certain safety hazards.

[0035] Embodiment 2:

[0036] On the basis of Example 1, the protective mechanism in this Example 1 can play a role in protecting the connecting piece 26 at the connection of the gate 4, but the protective box 6 in this mechanism is connected to the top of the connecting piece 26 by a sleeve manner. When it rains heavily or in strong winds, the protective box 6 will inevitably shake, thereby creating gaps, causing rainwater to penetrate into the protective box 6, which will also cause damage to the connection of the gate 4. The fixing mechanism in this application includes a fixing block 9 fixedly connected to both sides of the protective box 6, and a snap-in groove 10 is provided on the top of the fixing block 9. Both sides of the connecting piece 26 are fixedly connected with a stabilizing block 11, and the top of the stabilizing block 11 is fixedly connected with a snap-in block 12 used in conjunction with the snap-in groove 10.

[0048] Working principle: When the user uses the hydraulic gate hoist 1 to open and close the gate 4 on rainy days, the protective box 6 can protect the connection of the gate 4. The sealing plate 7 and the sealing ring 8 are provided to increase the sealing inside the protective box 6, further improving the protective effect of the protective mechanism, so that the connecting piece 26 is covered inside the protective box 6 and will not be corroded by rainwater, effectively extending the service life of the connecting piece 26 and the hydraulic gate hoist 1;

[0049] When the user uses the protection mechanism, the clamping block 12 in the fixing mechanism will be clamped into the clamping groove 10, and then the rotating block 13 and the anti-sliding block 24 are manually rotated, thereby driving the rotating rod 15, the rotating disk 16 and the first tooth 17 to rotate, and the first tooth 17 is rotated to drive the second tooth 19 to rotate, thereby driving the connecting plate 18, the moving plate 27 and the limit block 22 to move along the trajectory of the limit groove 23. At this time, the tension spring 21 is in a stretched state, and at the same time, it will drive the plug-in rod 20 to be plugged into the plug-in hole 25, so as to fix the protection box 6;

[0050] When the connecting member 26 needs to be inspected and maintained, the rotating disk 16 is continued to rotate manually. When the first tooth 17 on the rotating disk 16 rotates to have no contact with the second tooth 19 on the connecting plate 18, the tension generated by the tension spring 21 can drive the connecting plate 18, the movable plate 27, the limit block 22 and the plug-in rod 20 to reset. At this time, the protective box 6 is no longer restricted, the protective box 6 can be lifted manually, and then the connecting member 26 can be maintained.
