It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1: Figure 1-Figure 4 As shown, the utility model provides a municipal water supply pipeline flushing device, including a drill tip 1, a crushing head 2 is fixed on one surface of the drill tip 1, an end of the crushing head 2 away from the drill tip 1 is rotatably connected to a connecting piece 3 through a bearing, a cavity 4 is arranged in the crushing head 2, a flushing hole 5 connected to the cavity 4 is opened in a circumferential array on the surface wall of the crushing head 2, and a self-rotating component 6 is arranged on the connecting piece 3 and the crushing head 2.

[0023] The effect achieved by the entire embodiment 1 is that, under the impact of high-pressure water flow, the self-rotating component 6 can drive the drill tip 1 and the crushing head 2 to rotate automatically, so that the drill tip 1 and the crushing head 2 can break and crush the dirt attached to the inner wall of the pipe. The high-pressure water flow ejected from the flushing hole 5, driven by the rotating crushing head 2, can achieve 360-degree spraying of the high-pressure water flow, that is, the pipe can be flushed in all directions, with a better flushing effect, and shortening the cleaning time of the pipe.

[0024] Example 2: Figure 1-Figure 4As shown, the connecting member 3 includes a water storage chamber 301, one side wall of the water storage chamber 301 is fixedly connected to a high-pressure water pipe connection head 302, and the other side wall of the water storage chamber 301 is fixedly connected to a mounting pipe 303; the flushing hole 5 is inclined upward toward the mounting pipe 303, and the end of the mounting pipe 303 close to the flushing hole 5 is inclined downward toward the flushing hole 5; the self-rotating component 6 includes a bracket 601 fixed to the inner wall of the mounting pipe 303, and the middle part of the bracket 601 rotates through a bearing It is dynamically connected with a rotating rod 602, and fan blades 603 are fixed in a circular array on the surface of the rotating rod 602; fixed blocks 604 are fixed on the surface of the fan blades 603, and the fixed blocks 604 are fixed on the surface of the cavity 4; the bracket 601 is in a "cross" shape, and a circular hole 605 adapted to the rotating rod 602 is opened in the middle of the bracket 601, and the rotating rod 602 is rotatably connected in the circular hole 605 through a bearing; a cutting edge is provided on the surface of the crushing head 2, and a chip removal groove is opened on the surface of the cutting edge.

[0025] The effect achieved by the entire embodiment 2 is that the high-pressure water pipe connecting head 302 is configured to be compatible with the high-pressure pipe, so that the high-pressure water pipe connecting head 302 can achieve a sealed connection with the high-pressure water source. The connection method is an existing well-known technology, so it is not described in detail. The end of the mounting tube 303 close to the flushing hole 5 is inclined downward toward the flushing hole 5 to avoid the thickness of the mounting tube 303 affecting the straight-line range of the high-pressure water flow ejected from the flushing hole 5. The rotating rod 602 in the mounting tube 303 and the bracket 601 can realize the rotation of the fan blades 603 in the mounting tube 303 under the impact of the high-pressure water flow. Under the connection of the fixed block 604, the crushing head 2 and the drill tip 1 can be automatically rotated during use.

[0026] Working principle: When in use, the personnel first connect the high-pressure water pipe connection head 302 with another high-pressure pipe, and then the high-pressure water flow is transported to the connecting piece 3 through the high-pressure pipe and flushed into the cavity 4 through the rotating component 6. The water flow will rush out from the inclined flushing hole 5, and the high-pressure water flow can be sprayed from the rear to drive the drill tip 1 and the crushing head 2 to move forward. At the same time, the high-pressure water flow passing through the rotating component 6 will impact the fan blades 603, and the bracket 601 allows the rotating rod 602 to rotate accordingly in the connecting piece 3. Under the impact of the high-pressure water flow, the fan can be pushed The blades 603 rotate in the mounting tube 303, and the blades 603 and the crushing head 2 are fixed by the fixing block 604. Then, the rotating blades 603 can drive the crushing head 2 to rotate together, so that the drill tip 1 and the crushing head 2 can realize self-rotation under the impact force of the high-pressure water flow, and the blockages in the pipeline can be crushed and separated. At the same time, the water flow ejected from the flushing hole 5 cooperates with the rotating crushing head 2 to realize 360-degree flushing of the inner wall of the pipeline, so that the flushing force of the inner wall of the circular pipeline is consistent. In summary, the problems raised in the above background are solved.
