Abstract

The invention relates to the technical field of municipal equipment, and discloses a buoyancy type self-cleaning flood gate for an underground garage. The buoyancy type self-cleaning flood gate comprises a door frame, a floating gate body, a buoyancy cavity and a flood discharge cavity. The door frame is movably connected with the floating gate body, the floating gate body is arranged in the buoyancy cavity, and the buoyancy cavity communicates with the flood discharge cavity. According to the buoyancy type self-cleaning flood gate for the underground garage, when there is a light rain and water flow is relatively slow, the buoyancy cavity is a closed space, and a sediment accumulation phenomenon cannot occur. When there is a heavy rain, the floating gate body is triggered to stretch out to block water, one-time high-pressure water column cleaning can occur, so that less silt is accumulated at the bottom of the buoyancy cavity all the time, and it is ensured that the floating gate bodycan stretch out and draw back normally so as to guarantee normal passing of a vehicle. In addition, an inflation air bag carries out sealing protection on the top of the floating gate body, the siltand garbage are prevented from blocking the floating gate body, the force effect of the vehicle on the floating gate body is reduced, and location deformation of the floating gate body is reduced.

Description

technical field

[0001] The invention relates to the technical field of municipal equipment, in particular to a buoyant self-cleaning flood control gate for underground garages. Background technique

[0002] Such as Figure 6 As shown, it is an existing self-floating flood gate. The gate is installed in the underground chamber and is made of aluminum and polyethylene materials. It has low density and can easily float up and down. When a flood occurs, the water intake capacity is greater than The drainage capacity of the underground chamber, the water level in the underground chamber rises, the fork door rises with the rise of the water level, no additional energy and manual intervention are required, and the height of the fork door is automatically controlled by using the water inflow and discharge of the flood. After receding, the accumulated water is discharged, and the fork gate is lowered back to the ground to ensure smooth passage.

[0003] But in fact, running water wi...
