[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, a pipeline inlet cleaning device includes a plurality of filter rods 11, a rotating rod 2 and a plurality of blades 21.

[0022] A plurality of the filter rods 11 are fixed horizontally at intervals in the inlet of the pipe 1, and the large debris in the sewage pool 3 is blocked by the plurality of filter rods 11; the rotating rod 2 is vertically arranged on one side of the filter rod 11, and the rotating rod 2 passes through the inlet of the pipe 1, wherein the bottom of the rotating rod 2 can be placed at the bottom of the sewage pool 3, or the rotating rod 2 can be rotatably connected to the wall of the pipe 1; the top of the rotating rod 2 extends to the water surface of the sewage pool 3, wherein the rotating rod 2 can be rotatably connected to the wall of the sewage pool to prevent the sewage pipe 1 from being too far away from the water surface, causing the rotating rod 2 to tilt; a plurality of the blades 21 are fixed in parallel and at intervals on the rotating rod 2 in the inlet of the pipe 1, and by rotating the rotating rod 2, the plurality of blades 21 can be rotated accordingly; during the rotation of the rotating rod 2, the plurality of blades 21 respectively pass through the gap between two adjacent filter rods 11, wherein the uppermost blade 21 and the lowermost blade 21 in the inlet of the pipe 1 can respectively pass through the gap between the filter rod 11 and the top and bottom of the inlet of the pipe 1, and the plurality of blades 21 can be rotated to cut debris such as plastic bags blocked by the filter rod 11 to prevent the inlet of the pipe 1 from being blocked;

[0023] A platform can be built on the sewage pool 3, so that the staff can stand on the platform to rotate the rotating rod 2, so as to clean the debris at the entrance of the pipeline 1, avoiding the danger of people going into the water, reducing the labor intensity, and compared with the rotation of the rotating rod 2 controlled by the motor, the motor is easy to be damaged under the sewage pool 3 and is not easy to repair;

[0024] In order to facilitate the installation of the rotating rod 2 , the rotating rod 2 can be divided into two sections, the upper and lower sections, which are connected above the inlet of the pipeline 1 through a flange 4 .

[0025] In this embodiment, the blade 21 is rhombus-shaped; the rotating rod 2 in the entrance of the pipe 1 passes through the middle of the blade 21 in sequence. Since the rotating rod 2 is fixed to the middle of the blade 21, the four sides of the rhombus-shaped blade 21 can cut debris during the rotation of the rotating rod 2.

[0026] In this embodiment, the length of each blade 21 matches the horizontal width of the pipe 1, wherein the top blade 21 and the bottom blade 21 are the shortest and the middle blade 21 is the longest, so that the blade 21 can completely clean up the debris in the entrance of the pipe 1.

[0027] In this embodiment, the rotating rod 2 is arranged between the filter rod 11 and the entrance of the pipe 1. During the rotation of the rotating rod 2, one end of the multiple blades 21 can extend to the outside of the pipe 1. By rotating the rotating rod 2, the blades 21 can clean the debris on the entrance of the pipe 1 to prevent large debris from covering the entrance of the pipe 1.

[0028] In this embodiment, a hand wheel 22 is fixed on the top of the rotating rod 2, and the hand wheel 22 is convenient for a worker to manually rotate the rotating rod 2.

[0029] In this embodiment, a non-contact flow sensor is installed on the pipeline 1, and the sewage flow in the pipeline 1 is detected by the non-contact flow sensor. The flow sensor can transmit the detected flow to a receiving device or control system on the ground by wired or wireless means. The receiving device or control system displays the flow data. When the flow is lower than the threshold, the staff is reminded. The staff turns the rotating rod 2 to clean up the debris in the entrance of the pipeline 1 to make the flow normal. The non-contact flow sensor is preferably an ultrasonic flow sensor, and the threshold is the normal sewage flow in the sewage pipeline 1.

[0030] The use method of the utility model is as follows: during the sewage discharge process, when the staff finds that the flow rate is lower than the threshold value or the timing, the hand wheel 22 is turned to rotate the rotating rod 2, so that each blade 21 is rotated in the inlet of the pipe 1, and the blade 21 passes between two adjacent filter rods 11 to cut and clean the debris blocked by the filter rods 11.
