Description

Technical Field

[0001] The utility model relates to the technical field of chain derailment protection, in particular to a protection device for preventing the chain body of a rotary sewage cleaner from derailing. Background Technique

[0002] During the water transfer operation, the faults of unilateral jamming of the sewage cleaner and derailment of the chain body caused by foreign matters such as tree roots and net ropes often occur. The main reason for the faults is the unilateral foreign matter jamming of the rake during the operation of the sewage cleaner. One side of the rake is jammed and stationary. At this time, the mechanical protection of the shear pin cutting and the electrical protection action value of the motor overload have not been reached. The other side continues to rotate driven by the motor, resulting in the tilt of the rake and the derailment of the chain body. The purpose of this project is to design and install a protection device for preventing the chain body from derailing caused by unilateral jamming, which takes precedence over mechanical protection and electrical protection.

[0003] The existing protection devices for preventing the chain body of rotary sewage cleaners from derailing can basically meet people's usage requirements, but there are still some problems, which are specifically described as follows:

[0004] 1. The problem that it is difficult for the protection device for preventing the chain body of a rotary sewage cleaner from derailing to connect the wires. The laser sensor needs to be connected to the background operating system through wires. When connecting the wires, it is easy to fall off.

[0005] 2. The problem that it is difficult for the protection device for preventing the chain body of a rotary sewage cleaner from derailing to adjust the height of the laser sensor.
