Description

Technical Field

[0001] The utility model relates to the field of steel gates, in particular to a steel gate sealing structure. Background Art

[0002] Traditional steel frame gates are mainly used as auxiliary equipment tools for protecting and intercepting the drainage area of ​​some large reservoirs. With the development of modern industry and construction industry, more and more large waters will build flood control dams, and it is inevitable to build waterproof gates on the top of the flood control dams. With the continuous development of science and technology, the types of gates used in such flood control dams are also increasing, so that they can better meet the needs of use;

[0003] In view of this, Chinese patent number CN211872897U discloses a corrosion-resistant cast iron frame steel gate, which relates to the technical field of cast iron steel gates. By setting a chromium-nickel anti-corrosion coating on the surface of the steel gate body and the inner gate body, the corrosion resistance of the steel gate is greatly improved to prevent the steel gate from being corroded. By setting a drainage port, an inner gate body and a filter screen, and under the cooperation of a support plate, a hinge and a hydraulic cylinder, the effect of filtered drainage can be achieved when the entire steel gate body is not opened.

[0004] However, ordinary flood-proof steel frame gates rely on the rubber sealing strip on the outside to seal against the door frame when in use. When the gate is raised or lowered, it is easy to swing left and right, causing the compression between the rubber sealing strip and the door frame to change with the swing of the gate, which reduces the sealing of the gate when it is closed.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the outer side of the gate plate and the gate frame are sealed by squeezing a sealing slide inside the sealing slide groove, and the extrusion amount of the sealing slide inside the sealing slide groove is limited by the limiting bar and the limiting groove, so that the compression amount of the sealing slide is always consistent, thereby ensuring the sealing of the gate plate and the gate frame when closing the gate.
