Description

Technical Field

[0001] The utility model relates to the technical field of cast iron gates, in particular to a cast iron gate which can be lifted and lowered quickly. Background Art

[0002] A sluice is a hydraulic engineering structure built on rivers and channels that uses gates to control flow and regulate water levels. Closing the gates can block floods, tides or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry and domestic water use; opening the valves can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices serve as structures for retaining, discharging or taking in water.

[0003] When the existing cast iron gate is working, due to the sliding friction, the friction force is relatively large. After opening and closing many times, the door body and the guide rail are greatly worn, resulting in poor sealing. The existing cast iron gate still has some disadvantages to a certain extent. When the cast iron gate is in use, the gate body needs to be lifted and lowered. The existing cast iron gate is not fast enough when controlling the lifting and lowering movement of the gate body. This makes it impossible to automatically control the gate body to be lifted and lowered quickly when the cast iron gate is in use, which reduces the working efficiency of the cast iron gate when in use; when the cast iron gate is in use, the surface of the gate body needs to be protected and blocked. The existing cast iron gate does not have the surface protection of the gate body when in use. The cast iron gate has the function of protecting and blocking the surface, which makes it impossible for the cast iron gate to block large floating objects in the water flow when in use, and it is easy for the floating objects to impact the surface of the gate body, which is easy to cause the surface of the gate body to be damaged by the impact of the floating objects, shortening the service life of the gate body and wasting the cost; the cast iron gate needs to seal the dam body and the gate body when in use, and the existing cast iron gate has a poor sealing effect between the dam body and the gate body when in use, which makes it easy for water to seep out from between the dam body and the gate body when the cast iron gate is in use, reducing the sealing performance of the cast iron gate when in use, and it is not practical enough.
