Referring to fig. 8, the drainage pipeline sludge cleaning device further comprises a control module for monitoring the sludge height in the drainage pipeline 1, wherein the control module comprises a plurality of ultrasonic sensors arranged on the inner wall of the drainage pipeline 1 along the length direction of the drainage pipeline 1 and a P L C controller arranged at the top of the inner wall of the drainage pipeline 1;
the ultrasonic sensor is used for measuring the height of sludge in the drainage pipeline 1 and sending a first trigger signal when the height of the sludge in the drainage pipeline 1 is higher than a preset first set value; when the height of the sludge in the drainage pipeline 1 is lower than a preset second set value, a second trigger signal is sent out, and the second set value is smaller than the first set value;
the ultrasonic sensor is electrically connected with a signal input end of a P L C controller, a signal output end of the P L C controller is electrically connected with the first motor 62 and the second motor 82 respectively, and the P L C controller is used for receiving a first trigger signal and a second trigger signal;
when the P L C controller receives the first trigger signal, the first motor 62 and the second motor 82 are controlled to start, and when the controller receives the second trigger signal, the first motor 62 and the second motor 82 are controlled to stop working.
When the ultrasonic sensor senses that the sludge in the drainage pipeline 1 is lower than a second set value, the P L C controller correspondingly controls the first motor 62 and the second motor 82 to stop working after receiving the second trigger signal, so that the sludge cleaning work is stopped, and the automation degree of the sludge cleaning of the drainage pipeline 1 is further improved.
The above-mentioned embodiments are merely illustrative of the present invention, and are not restrictive, and those skilled in the art can make modifications, which do not contribute to the inventive concept if necessary, after reading the present specification, but are protected by patent laws within the scope of the appended claims.
