DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1-2 , is the first embodiment of the present invention, which provides a rotating mechanism, including:

[0028] The accommodating assembly 100 comprises a cylinder 101 with openings at both ends, a first end cover 102 and a second end cover 103 are respectively provided at both ends of the cylinder 101, and a water inlet 104 is provided on the first end cover 102;

[0029] The rotating assembly 200 includes a rotating shaft 201 coaxially rotatably arranged inside the cylinder 101, an impeller 202 is arranged on the rotating shaft 201, one end of the rotating shaft 201 passes through the second end cover 103 and extends to the outside of the cylinder 101, and the end of the rotating shaft 201 extending outside the cylinder 101 is provided with a water outlet 203, and the portion of the rotating shaft 201 located inside the cylinder 101 is provided with at least one connecting port 204 connecting the inside of the cylinder 101 and the water outlet 203.

[0030] The upper rotating mechanism is driven by a high-pressure water source. Specifically, the high-pressure water enters the cylinder 101 from the water inlet 104, and then flows to the other end of the cylinder 101. During the flow of the high-pressure water inside the cylinder 101, it passes through the impeller 202, drives the impeller 202 to rotate, and then drives the rotating shaft 201 inside the impeller 202 to rotate; after passing through the impeller 202, the high-pressure water flows to the other end of the cylinder 101, and then enters the water outlet 203 inside the rotating shaft 201 through the connecting port 204, and is discharged from the water outlet 203.

[0031] Furthermore, the rotating assembly 200 further includes an annular member 205 coaxially fixed to the inner wall of the cylinder 101 , and the impeller 202 is coaxially rotatably disposed inside the annular member 205 .

[0032] The setting of the ring member 205 is used, on the one hand, to support the impeller 202 and the rotating shaft 201, specifically, the outer end of the impeller 202 is rotatably set on the inner wall of the ring member 205; on the other hand, it is used to concentrate the water flow so that the water flow passes through the impeller 202 to better drive the impeller 202 to rotate. Specifically, the ring member 205 is sealed between the outer end of the impeller 202 and the inner wall of the cylinder 101 to prevent the water flow from passing through the gap between the outer end of the impeller 202 and the inner wall of the cylinder 101 to ensure that the water flow passes through the impeller 202. Combined with the high pressure effect of the water flow, the water flow can drive the impeller 202 well.

[0033] Furthermore, the annular member 205 is detachably fixed to the interior of the cylinder 101 by means of screws, and the outer wall of the annular member 205 and the inner wall of the cylinder 101 are sealed and connected.

[0034] The annular member 205 is fixed to the inner wall of the cylinder 101 by screws, and is easy to assemble and disassemble. Specifically, the screws extend from the outer wall of the cylinder 101 to the inner wall of the cylinder 101 and are finally nailed to the annular member 205. The screw position here is also sealed to prevent water leakage.

[0035] Furthermore, the first end cover 102 is detachably mounted on the end of the cylinder 101 by means of screws, and the first end cover 102 and the cylinder 101 are sealed and connected.

[0036] Furthermore, the second end cover 103 is detachably arranged at the end of the cylinder 101 by screws, the second end cover 103 and the cylinder 101 are sealed and connected, a bearing 105 is arranged at the center of the second end cover 103, and the rotating shaft 201 rotates through the second end cover 103 through the bearing 105.

[0037] The first end cover 102 and the second end cover 103 are both detachably connected to the cylinder body 101 by screws, and are easy to assemble and disassemble. The first end cover 102 and the second end cover 103 are both sealedly connected to the cylinder body 101 to prevent water leakage.

[0038] Example 2, reference Figure 1-4 , which is the second embodiment of the present invention, is different from the previous embodiment in that a pipe cleaning device includes an upper rotating mechanism and also includes,

[0039] The brush assembly 300 includes a brush body 301, one end of the brush body 301 is coaxially fixed in the water outlet 203 of the rotating shaft 201, the brush body 301 is a hollow structure, the water outlet 203 is connected to the inside of the brush body 301, the side wall of the brush body 301 is provided with water spray holes 302, and the outer wall of the brush body 301 is provided with bristles 303.

[0040] The brush assembly 300 is fixed to the outer end of the rotating shaft 201. The rotation of the rotating shaft 201 drives the brush assembly 300 to rotate, and then cleaning is performed. Specifically, the water inlet 104 on the first end cover 102 is connected to a high-pressure water source such as a high-pressure pump through a hose. The entire cleaning device is placed in the pipe fitting, and high-pressure water is sent in to drive the rotating shaft 201 to rotate. The rotating shaft 201 drives the brush body 301 to rotate, so that the bristles 303 on the brush body 301 clean the inner wall of the pipe fitting. At the same time, the water after driving the impeller 202 to rotate enters the water outlet 203 through the connecting port 204, then flows into the inside of the brush body 301, and finally is sprayed out from the water spray hole 302 on the side wall of the brush body 301, thereby flushing the inner wall of the pipe fitting and removing impurities brushed off.

[0041] Furthermore, the outer wall of the brush body 301 and the inner wall of the water outlet 203 are sealed and connected, and the brush body 301 and the rotating shaft 201 are fixed by screws.

[0042] The end of the brush body 301 extends into the water outlet 203 and is then fixed by screws. This fixing method is a detachable fixing method, which facilitates the replacement of the brush assembly 300.

[0043] Furthermore, the water spray holes 302 are evenly distributed between adjacent bristles 303 .

[0044] The bristles 303 and the water spray holes 302 are arranged at intervals on the side wall of the brush body 301 so that the water flow can better wash away the impurities brushed off.

[0045] Example 3, reference Figure 1-4, which is the third embodiment of the present invention. Different from the previous embodiment, it also includes a support assembly 400. The support assembly 400 includes a sleeve 401. The side walls of the first end cover 102 and the second end cover 103 are circumferentially provided with multiple sleeves 401. An inner rod 402 is passed through the sleeve 401. One end of the inner rod 402 extends to the outside of the sleeve 401. A spring 403 is provided between the other end of the inner rod 402 and the inside of the sleeve 401.

[0046] Furthermore, a ball 404 is movably provided at one end of the inner rod 402 away from the sleeve 401 .

[0047] The setting of the support component 400 is used to make the entire pipe cleaning device have good applicability to pipes with different inner diameters. Specifically, the support component 400 is a telescopic rod structure that can be extended and retracted radially along the cylinder 101. Through the extension and retraction of the support component 400, the entire cleaning device is supported on the inner wall of the pipe to meet the cleaning needs of pipes with different inner diameters. Of course, for pipes with different inner diameters, brush components 300 with different outer diameters need to be replaced. During cleaning, since the ball 404 is movably arranged at the outer end of the support component 400, the entire cleaning device does not include rolling contact between the bristles 303 and the inner wall of the pipe. By pushing inward or pulling outward the hose connected to the water inlet 104, the entire cleaning device can be moved axially in the pipe, thereby achieving cleaning of the entire inside of the pipe.

[0048] Through the design of the support assembly 400 and the rotating mechanism, the entire cleaning device can rotate and move axially inside the pipe fitting, thereby cleaning the inner wall of the entire pipe fitting. The cleaning is convenient, the labor intensity is low, and the efficiency is high. While cleaning, high-pressure water flushing is carried out to improve the cleaning effect of the inner wall of the pipe fitting, and less impurities remain.
