Description

Technical Field

[0001] The utility model relates to the field of sewage suction vehicles, in particular to a sewage suction vehicle which is convenient for pipeline connection. Background Art

[0002] The sewage suction truck is a new type of sanitation vehicle that collects, transfers, cleans and transports sludge and sewage to avoid secondary pollution. The sewage suction truck can self-prime and self-drain, has a fast working speed, a large capacity, and is convenient to transport. It is suitable for collecting and transporting liquid substances such as feces, mud, and crude oil. When the sewage suction truck is in use, the sewage suction pipe and the external hose are connected to each other, and the lower end of the hose is inserted into the sludge and sewage, which is convenient for the sewage suction truck to suck sludge and sewage. The hose and the sewage suction pipe are connected by a clamp structure. For example, the Chinese utility model type patent with the public document number: CN211449942U discloses a clamp structure for pipe connection. In the utility model, the hard tooth rings on both sides of the clamp body are pressed on the outer walls of the two pipes to be connected respectively. The tightening of the fastening bolts presses the tip of the tooth ring into the outer wall of the pipe and causes the outer wall of the pipe to undergo plastic deformation, so that there will be no loosening and pulling-out phenomenon between the clamp and the pipe;

[0003] However, when the sewage suction pipe of the sewage suction truck is connected to the hose, the hose is put on the sewage suction pipe, and the clamp is put on the hose. The hose is fixedly connected to the sewage suction pipe by tightening the fastening bolts. When disassembling, the bolts are turned in the opposite direction to loosen them. The operation is extremely laborious. Although the tooth ring of the clamp can fix the hose, the hose and the sewage suction pipe are frequently disassembled, and the hose frequently undergoes plastic deformation, which makes the fixed connection position of the hose easy to be damaged. For example, the surface of the hose is penetrated by the hard tooth ring, etc., so improvement is needed. Utility Model Content
