[0027] Furthermore, the liquid level difference sensor 500 is disposed on the interception net 800 to detect the liquid level difference on both sides of the interception net 800 , and the liquid level difference sensor 500 is electrically connected to the first driving device 300 .

[0028] Through the above technical scheme, the automatic cleaning device of the filler interception net of the utility model is provided with a guide rail assembly 100 on the outer side of the outline of the interception net 800, and a first driving device 300 is provided to drive the movable block 200 to slide on the guide rail assembly 100, the movable block 200 is connected with a cleaning assembly 400, and the cleaning assembly 400 can clean the interception net 800 when sliding with the movable block 200. In addition, the liquid level difference sensor 500 can monitor the water level difference flowing on both sides of the interception net 800, and is electrically connected to the first driving device 300 for communication; in this way, when the water level flowing on both sides of the interception net 800 is greater than the predetermined level set by the liquid level difference sensor 500, After the water level on both sides of the interception net 800 is lower than the preset value set by the liquid level difference sensor 500, the liquid level difference sensor 500 feedbacks a signal to stop the first driving device 300 from working. Through the above technical scheme, the interception net 800 has the function of automatic cleaning, which avoids the suspension of sewage treatment process due to the blockage of the interception net 800 and saves labor and cost.

[0029] In order to enable the cleaning assembly 400 to effectively clean the blockage when cleaning the interception net 800, in this embodiment, the cleaning assembly 400 includes a second drive device 410 and a roller brush 420. The second drive device 410 is installed on the movable block 200. The second drive device 410 is connected to one end of the roller brush 420 and drives the roller brush 420 to rotate. At this time, the second drive device 410 includes a motor and a reduction box. The output shaft of the motor is connected to the input shaft of the reduction box, and the output shaft of the reduction box is connected to the roller brush 420. The other end of the roller brush 420 is extended along the direction of the vertical guide rail assembly 100. With such a configuration, the roller brush 420 can rotate under the drive of the motor to increase the speed of cleaning the blockage. After the reduction is reduced by the reduction box, the torque is increased, so that the rotation torque of the roller brush 420 is large to avoid rolling jams.

[0030] Taking into account the large area of ​​the interception net 800, when the roller brush 420 is connected to the second drive device 410 by relying solely on one end thereof, the end of the roller brush 420 away from the second drive device 410 is prone to twisting and tilting. In view of this, in order to avoid the end of the roller brush 420 away from the second drive device 410 from tilting, in the present embodiment, the guide rail assembly 100 includes an upper guide rail 110 and a lower guide rail 120, the upper guide rail 110 and the lower guide rail 120 are respectively located above and below the interception net 800, the upper guide rail 110 and the lower guide rail 120 are arranged in parallel, the movable block 200 is slidably installed on the upper guide rail 110, and the end of the roller brush 420 away from the second drive device 410 is slidably connected to the lower guide rail 120.

[0031] Furthermore, the cleaning assembly 400 further includes a roller 430, which is rotatably mounted on one end of the roller brush 420 away from the second driving device 410, and the roller 430 is rollingly connected to the lower guide rail 120. The roller 430 is slidably connected to the lower guide rail 120, so that the roller brush 420 slides more smoothly under the drive of the movable block 200.

[0032] In order to facilitate the installation of the interception net 800, in the present embodiment, the automatic cleaning device of the filler interception net also includes: an upper support member 600 and a lower support member 610, the upper support member 600 and the lower support member 610 are respectively located at the upper and lower ends of the interception net 800, the upper and lower ends of the interception net 800 are respectively connected to the upper support member 600 and the lower support member 610, the upper guide rail 110 is fixedly installed on the upper support member 600, and the lower guide rail 120 is fixedly installed on the lower support member 610.

[0033] In some embodiments, the automatic cleaning device for the filler intercepting net further includes two limit switches 700, which are respectively installed at both ends of the upper rail 110 assembly 100 in the extension direction. The two limit switches 700 are arranged on the upper rail 110 to avoid contact with sewage; in addition, the automatic cleaning device for the filler intercepting net further includes a controller, which is electrically connected to the liquid level difference sensor 500, the first drive device 300, the second drive device 410 and the two limit switches 700.

[0034] In this way, after the liquid level difference sensor 500 detects that the water level on both sides of the interception net 800 reaches the preset value, the signal is transmitted to the controller, and the controller controls the first drive device 300 and the second drive device 410 to work. The first drive device 300 works to make the movable block 200 slide along the guide rail assembly 100, and the second drive device 410 works to make the roller brush 420 rotate to clean the interception net 800. Then, after the movable block 200 slides to a limit switch 700 installed on the upper guide rail 110, the limit switch 700 is turned on. 700 triggers the signal and feeds the signal back to the controller. After receiving the signal, the controller controls the first drive device 300 to reverse, so that the movable block 200 slides in the opposite direction, thereby triggering another limit switch 700, and repeats this process. After that, when the water surface on both sides of the interception net 800 is lower than the preset value of the liquid level difference sensor 500, the liquid level difference sensor 500 sends a signal again, and the controller controls the first drive device 300 and the second drive device 410 to stop working, thereby realizing the automatic cleaning function of the interception net 800.

[0035] It should be noted that the controller can be a single chip microcomputer, a PWM controller, a PLC controller, a microprocessor or other electrical components capable of receiving external signals and outputting execution command signals, and is not specifically limited here.

[0037] In some embodiments, the automatic cleaning device for the filler interception net further comprises a flow pusher, which is installed on the side of the interception net 800 facing the cleaning component 400. When the cleaning component 400 cleans the interception net 800, the flow pusher can be started to push the flow to speed up the flow of sewage to avoid the accumulation of the cleaned filler in front of the interception net 800.

[0038] In some embodiments, the liquid level difference sensor 500 is an ultrasonic liquid level difference sensor 500. The ultrasonic liquid level difference sensor 500 uses ultrasonic beams for measurement, so there is no need to directly contact the measured sewage, thus avoiding the problems of contamination, corrosion or wear during the monitoring process.
