[0046] In one embodiment, Figures 1 to 5 As shown, the cleaning assembly 2 includes a pipeline connector 201 and a plurality of cleaning pipelines 202. The end surface of the pipeline connector 201 is drivingly connected to the main shaft 3011. The plurality of cleaning pipelines 202 are respectively connected to a plurality of side surfaces of the pipeline connector 201 and are connected to the communication cavity through the end surface of the pipeline connector 201. By providing a plurality of cleaning pipelines 202 connected to the pipeline connector 201, the cleaning area of ​​the trash rack is effectively expanded, which is conducive to improving the working efficiency of the automatic cleaning device for the trash rack.

[0047] Specifically, Figure 1 and Figure 4 As shown, the end of the pipeline connector 201 close to the main shaft 3011 is the end face of the pipeline connector 201 , and the surface of the pipeline connector 201 perpendicular to the end face is the side face of the pipeline connector 201 .

[0048] In one embodiment, threaded holes are provided on several side surfaces of the pipe connector 201, and the first end of the cleaning pipe 202 has a threaded structure, and the first end of the cleaning pipe 202 is inserted into the threaded hole and threadedly connected to the pipe connector 201. By threading the cleaning pipe 202 and the pipe connector 201, the cleaning pipe 202 itself can rotate around the thread, which is conducive to adjusting the installation angle of the cleaning pipe 202, further expanding the cleaning range of the automatic cleaning device for the trash rack, and improving the cleaning effect of the trash rack.

[0049] Specifically, in this embodiment, the pipeline connector 201 is a five-way connector, which has one connector and four interfaces. The five-way connector has five connected passages inside. The connector corresponding to the first passage is arranged on the end face of the pipeline connector 201 and is transmission-connected to the main shaft 3011 and is connected to the connecting cavity at the same time. The interfaces corresponding to the second passage, the third passage and the fourth passage are all arranged on the side of the pipeline connector 201 and are respectively connected to the four cleaning pipelines 202, that is, the threaded holes are correspondingly opened at the interface positions. Therefore, the high-pressure water flowing out of the connecting cavity can flow into the corresponding cleaning pipeline 202 through the five passages, and be sprayed out from the cleaning pipeline 202 to clean the trash rack.

[0050] Specifically, the joint corresponding to the end surface of the pipe connector 201 is transmission-connected to the main shaft 3011 through the coupling 5, so that the pipe connector 201 and the main shaft 3011 can rotate synchronously and the pipe connector 201 and the main shaft 3011 are tightly sealed.

In the adjustment position, the locking nut 203 is away from the side of the pipeline connector 201 so that the cleaning pipeline 202 can rotate. By setting the locking nut 203, after the installation angle of the cleaning pipeline 202 is adjusted and confirmed, the cleaning pipeline 202 is locked and fixed, so as to prevent the cleaning pipeline 202 from changing its angle at will during operation, thereby affecting the cleaning effect of the trash rack.

[0052] In one embodiment, Figures 1 to 5 As shown, the trash rack automatic cleaning device also includes a nozzle 4, which is connected to the second end of the cleaning pipeline 202. By providing the nozzle 4, the water spraying range can be controlled and adjusted, which is beneficial to improving the cleaning effect of the trash rack.

[0053] When using the automatic cleaning device for the trash rack of the present embodiment, first, the automatic cleaning device for the trash rack is fixed to the trash rack through the connecting hole 30231 on the first fixing plate 3023; then, the cleaning pipeline 202 is rotated to make the nozzle 4 better align with the trash rack, and is locked and fixed with the locking nut 203; finally, the driving motor 301 is started, and the main shaft 3011 of the driving motor 301 drives the pipeline connector 201 to rotate, and the pipeline connector 201 drives the cleaning pipeline 202 to rotate; at the same time, water is supplied to the cleaning pipeline 202 through the water supply structure 1, and the high-pressure water is finally sprayed out through the nozzle 4 to clean the trash rack.
