[0022] according to Figure 1 、 2 As shown in Figures 3 and 4, a cleaning device for a gas pipeline is proposed in this embodiment, comprising a cleaning block 1, a second conical head 4 being provided at one end of the cleaning block 1, a first conical head 2 being provided at the other end of the cleaning block 1, a first jet assembly being provided on the outer side of the second conical head 4, and a second jet assembly being provided on the outer side of the first conical head 2;
[0023] The second conical head 4 is installed at the head of the cleaning block 1, and the first nozzle 3 is installed at the tail of the cleaning block 1. When the cleaning block 1 moves in the pipeline, the first jet component on the outside of the second conical head 4 will flush the blockage in the pipeline and in front of the second conical head 4 and flush the blockage. The second jet component on the outside of the first conical head 2 will flush the pipeline for the second time from behind the second conical head 4. During the flushing process, a forward reverse thrust is applied to the cleaning block 1 to improve the passing rate of the cleaning block 1 in the pipeline.
[0024] A plurality of movable arms 12 are provided on the outside of the cleaning block 1. The movable arms 12 are evenly arranged in the circumferential direction of the axis of the cleaning block 1. The lower ends of the movable arms 12 are hinged to the cleaning block 1. The upper ends of the movable arms 12 are provided with hemispherical sleeves 10. The hemispherical sleeves 10 are fixedly connected to the movable arms 12. A rolling ball 11 is provided on the end of the hemispherical sleeve 10 away from the movable arm 12.

[0025] A spring rod structure is provided between the movable arm 12 and the cleaning block 1 for providing elastic support to the movable arm 12 .
[0026] A spring-loaded rod structure propels each movable arm 12 outward toward the sides of the cleaning block 1. The ball 11 atop each arm 12 contacts the inner wall of the pipe, positioning the cleaning block 1 in the center of the pipe. This ensures smooth movement along the pipe axis, effectively clearing obstructions. The nested design of the ball 11 and hemispherical sleeve 10 not only supports forward and backward movement of the cleaning block 1, but also allows the cleaning block 1, first conical head 2, and second conical head 4 to rotate within the pipe, providing enhanced flexibility.
[0027] It should be further explained that one end of the cleaning block 1 is fixedly connected to one end of the first conical head 2, and the other end of the cleaning block 1 is fixedly connected to one end of the second conical head 4. A push rod 7 is provided at the end of the first conical head 2 away from the cleaning block 1. The push rod 7 is fixedly connected to the first conical head 2, and the push rod 7 is hollow inside.
