Description
Technical Field
[0001] The utility model relates to the technical field of gates, in particular to a detachable water-stopping device for gates. Background Art
[0002] Gates are control facilities used to close and open water channels. They are divided into steel gates, cast iron gates, wooden gates, reinforced concrete gates and composite gates according to the materials used to make the gate leaves. Among them, steel gates and cast iron gates are the most widely used. At present, cast iron gates used in China generally have insufficient water stopping power; the working environment of water stopping devices is poor, resulting in the need to replace water stopping devices at regular intervals. Existing water stopping devices are usually directly embedded in the frame, which is difficult to replace. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a detachable water-stopping device for a gate in view of the above-mentioned technical deficiencies. The cooperation of a set pressure plate and an L-shaped sealing strip is adopted to solve the problems of difficulty in replacing the existing water-stopping device and insufficient water-stopping force.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a detachable water-stop device for a gate, comprising a plurality of water-stop strips, the water-stop strips comprising a pressure plate and an L-shaped sealing strip, the L-shaped sealing strip comprising a pressure edge portion and a sealing edge portion which are perpendicular to each other, the pressure plate is crimped on the outer side of the pressure edge portion, the sealing edge portion is crimped on one side of the gate plate, the pressure plate is provided with a plurality of through holes, screws are passed through the through holes, the pressure plate is fixedly connected to the frame of the gate by the screws, and the pressure edge portion is arranged between the pressure plate and the frame.
[0005] To further optimize the technical solution, a plurality of protrusions are provided on both sides of the edge pressing portion along the length direction.
[0006] To further optimize the technical solution, arcuate ridges are provided at positions where both sides of the gate plate meet the edge sealing portion, and grooves are provided at positions of the edge sealing portion corresponding to the arcuate ridges.
[0007] Compared with the prior art, the utility model has the following advantages: 1. The L-shaped sealing strip and the edge pressing part are detachably connected to the inner side of the frame by screws, and the L-shaped sealing strip can be respectively used to seal the gate and the frame after closing the gate; 2. When the gate is opened or closed, the arc-shaped convex ridges always slide in the grooves of the L-shaped sealing strips on both sides of the gate, further increasing the contact area between the gate and the edge sealing part, and at the same time preventing mud and sand from entering the edge sealing part to affect the service life of the L-shaped sealing strip.
