[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0027] like Figure 1-Figure 3 As shown, a pipe internal cleaning device disclosed in this application includes a supporting main shaft 1. The interior of the supporting main shaft 1 is a hollow structure. The front end of the supporting main shaft 1 is connected to a rotating nozzle 2. The rear end of the supporting main shaft 1 can be connected to a water supply pipe.

[0028] A plurality of lateral support rods 3 are evenly arranged along the circumference of the outer side of the support main shaft 1, and the plurality of lateral support rods 3 are parallel to the support main shaft 1; a first roller 4 is connected to one end of the lateral support rod 3 close to the rotating nozzle 2, and a second roller 5 is connected to the other end of the lateral support rod 3, and the distance between the outermost side of the first roller 4 and the axis of the support main shaft 1 is equal to the distance between the outermost side of the second roller 5 and the axis of the support main shaft 1;

[0029] The lateral support rods 3 are movably connected to the support main shaft 1 through a group of adjustment components 6. A control unit 7 is installed at one end of the support main shaft 1. Multiple groups of adjustment components 6 are connected to the control unit 7. The control unit 7 can synchronously adjust the distance between multiple lateral support rods 3 and the support main shaft 1 through multiple groups of adjustment components 6.

[0030] In the above embodiments, the support spindle 1 of the present application not only provides a mounting base for the multiple lateral support rods 3, but its internal hollow structure can also transport water from the water supply pipe to the rotating nozzle 2 at the end, so that the rotating nozzle 2 can use the water flow to clean the interior of the pipe. The rotating nozzle 2 is a common type of nozzle in reality. When it is in operation, it can use the driving force of the water flow process to achieve the effect of spraying water while rotating. In this way, when the rotating nozzle 2 moves along the interior of the pipe with the support spindle 1, it can efficiently and quickly complete the cleaning work inside the pipe.

[0031] The multiple lateral support rods 3 on the outside of the support main shaft 1 can be adjusted simultaneously by the control unit 7 so that the distance between the multiple lateral support rods 3 and the support main shaft 1 is adapted to the inner diameter of the pipe to be cleaned. That is, when the entire device of the present application enters the pipe to be cleaned, the multiple lateral support rods 3 can make the first roller 4 and the second roller 5 at their respective ends contact the inner wall of the pipe, so that the support main shaft 1 can move forward smoothly along the inner wall of the pipe to be cleaned via the multiple first rollers 4 and the second roller 5, so that the rotating nozzle 2 at its front end can efficiently and evenly complete the cleaning work inside the pipe. Compared with the prior art, the present application reduces the labor intensity of workers when cleaning the pipe and improves the cleaning effect. Moreover, because the distance between the multiple lateral support rods 3 and the support main shaft 1 can be adjusted by the control unit 7, the cleaning device of the present application can be applied to pipes of various specifications in actual use, especially for some small-diameter pipes that are difficult for humans to enter. The present application can adapt well to them.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, the adjustment assembly 6 includes two parallel connecting rods 61, one end of the connecting rod 61 is hinged to the outer wall of the support main shaft 1, and the other end of the connecting rod 61 is hinged to the lateral support rod 3, and one side of the middle position of one of the connecting rods 61 is connected to the control unit 7.

[0033] In the above embodiment, the lateral support rod 3 is connected to the support main shaft 1 via two mutually parallel connecting rods 61, and one end of the connecting rod 61 is hinged to the lateral support rod 3, and the other end of the connecting rod 61 is hinged to the support main shaft 1. In this way, the lateral support rod 3, the support main shaft 1, and the connecting rod 61 can form a four-bar linkage. The control unit 7 can synchronously adjust the distance between the multiple lateral support rods 3 and the support main shaft 1 by synchronously controlling the angle between the connecting rod 61 on one side of the multiple lateral connecting rods 61 and the support main shaft 1. Moreover, during the adjustment process, since both ends of the lateral support rod 3 are simultaneously restricted by the two connecting rods 61, it can be ensured that it always remains parallel to the support main shaft 1 when being adjusted by the control unit 7, so that after adjustment, the first roller 4 and the second roller 5 at its two ends can synchronously contact the inner wall of the pipe.

[0034] Furthermore, if Figure 1 and Figure 2 As shown, the control unit 7 includes a mounting sleeve 71, which is sleeved on the tail of the support spindle 1 and is slidably connected thereto. A plurality of positioning rods 72 are evenly hinged to the outer side of the mounting sleeve 71 along the circumferential direction. The ends of the plurality of positioning rods 72 away from the mounting sleeve 71 are respectively hinged to the middle positions of the plurality of lateral support rods 3 on the adjacent side.

[0035] The end of the mounting sleeve 71 away from the rotary spray head 2 is rotatably connected to the rotating sleeve 73 , and the rotating sleeve 73 is sleeved on the supporting main shaft 1 and the two are threadedly connected.

[0036] In the above embodiment, the number of positioning rods 72 is equal to the number of lateral support rods 3, and a positioning rod 72 is hinged at the position corresponding to each lateral support rod 3 on the mounting sleeve 71. These positioning rods 72 are hinged to the middle position of one of the corresponding connecting rods 61 on the lateral support rod 3 at their corresponding position at one end away from the support main shaft 1. In this way, by pushing the mounting sleeve 71 along the axial direction of the support main shaft 1, the connecting rods 61 to which they are connected can be pushed synchronously through multiple positioning rods 72, so that the angles between these connecting rods 61 and the support main shaft 1 change, thereby achieving the effect of synchronously adjusting the distance between multiple lateral support rods 3 and the support main shaft 1. The outer side of the tail of the support main shaft 1 of the present application is provided with an external thread, and the interior of the rotating sleeve 73 is provided with an internal thread matching it, and one end of the rotating sleeve 73 is rotatably connected to the end of the mounting sleeve 71 away from the rotating nozzle 2 (for example, a bearing can be set between the rotating sleeve 73 and the mounting sleeve 71, and the outer ring of the bearing is fixedly connected to the inner wall of the rotating sleeve 73, and the inner ring of the bearing is fixedly connected to the outer wall of the mounting sleeve 71, so that the rotating sleeve 73 and the mounting sleeve 71 can be rotatably connected through the bearing). In this way, the worker screws the rotating sleeve 73 along the external thread section on the support main shaft 1 to drive the mounting sleeve 71 to move along the axis of the support main shaft 1, thereby synchronously adjusting the distance between the multiple lateral support rods 3 and the support main shaft 1. After adjusting to the appropriate position, stop screwing the rotating sleeve 73 to fix the multiple lateral support rods 3 in the desired position. This structure is not only simple but also very convenient to operate.

[0037] Furthermore, if Figure 1-Figure 3 As shown, the first roller 4 includes an anti-skid wheel 41 , the center of the anti-skid wheel 41 is connected to the output end of a wheel motor 42 , and the housing of the wheel motor 42 is fixedly mounted on the front end of the corresponding lateral support rod 3 through an extension plate 43 .

[0038] In the above embodiment, each first roller 4 of the present application is equipped with an independent wheel motor 42. In this way, the first roller 4 as a whole becomes a driving wheel. During cleaning, multiple first rollers 4 can move the entire device within the pipeline, improving the convenience of use. In addition, the first roller 4 of the present application is located close to the rotating nozzle 2, and the area it contacts will have a lot of mud, water and dirt. In order to prevent the wheel driven by the wheel motor 42 from slipping when it is working, the wheel driven by the wheel motor 42 of the present application is a non-slip wheel 41.

[0039] Furthermore, if Figure 1 and Figure 2As shown, the second roller 5 includes a pin 51, which passes through the tail of one of the lateral support rods 3 and is fixedly connected therebetween. Two guide wheels 52 symmetrical about the lateral support rod 3 are sleeved on the pin 51, and the two guide wheels 52 are both rotatably connected to the pin 51.

[0040] In the above embodiments, since the tail of the support main shaft 1 is connected to the water supply pipe, as the entire device of the present application moves in the pipe, the length of the water supply pipe dragged by its tail will continue to increase, which will also correspondingly increase the load-bearing capacity of the tail of the support main shaft 1. The second roller 5 at the tail of the support main shaft 1 of the present application is composed of two guide wheels 52 strung together by a pin shaft 51, which can effectively improve the load-bearing capacity of the tail of the support main shaft 1 and make its crawling process sufficiently smooth.

[0041] Furthermore, if Figure 1 and Figure 3 As shown, an annular mounting plate 8 is provided on the side of the rotating nozzle 2 close to the second roller 5. The annular mounting plate 8 is fixedly sleeved on the supporting main shaft 1. A plurality of waterproof cameras 9 are evenly arranged on the circumference of the annular mounting plate 8 close to the side of the rotating nozzle 2.

[0042] In the above embodiment, during the process of cleaning the inside of the pipeline, the multiple waterproof cameras 9 are supported on the front end of the main shaft 1 and installed on the annular mounting plate 8 in the above manner, so that the operating worker can observe the cleaning status of the inside of the pipeline in real time to ensure the final cleaning quality.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, a storage battery 10 is fixedly installed in the middle position of the supporting main shaft 1 , and the storage battery 10 is electrically connected to the waterproof camera 9 and the wheel motor 42 on the anti-skid wheel 41 .

[0044] In the above embodiment, the energy storage battery 10 not only ensures that sufficient power is provided to the waterproof camera 9 and the wheel motor 42 on the anti-skid wheel 41 during use, but also installs the energy storage battery 10 with a certain weight in the middle position of the supporting main shaft 1 so that the center of gravity of the entire device is as close to the middle as possible, so as to improve its stability during transportation and use.

[0045] Furthermore, if Figure 1-Figure 3 As shown, there are three lateral support rods 3 and three waterproof cameras 9 .

[0046] In the above embodiment, the monitoring angle of the general camera is between 90° and 120°. Therefore, in order to observe the whole circumference of the inside of the pipeline, at least three waterproof cameras 9 are required. When the support spindle 1 moves along the pipeline, Figure 4 As shown, if a lateral support rod 3 is provided, it is easy to tilt and fall during the movement; Figure 5As shown, if two lateral support rods 3 are provided, and the angle between the two lateral support rods 3 is 180°, most of the weight of the entire device will fall on one of the lateral support rods 3, which will increase the risk of damage to the lateral support rod 3 and make it inconvenient to place it in the pipeline; Figure 6 As shown, if the angle between the two lateral support rods 3 is less than 180°, the device can easily deviate to that side during movement due to the lack of a limit on one side, and the stability is poor. However, when three lateral support rods 3 are evenly spaced around the support main shaft 1 and the angle between adjacent support rods is 120°, the three lateral support rods 3 can not only keep the support main shaft 1 in the center position, but also share most of its weight with at least two lateral support rods 3, thereby reducing the risk of damage to the lateral support rods 3. Therefore, the present application provides at least three lateral support rods 3 around the support main shaft 1.

[0047] The operating principle of this embodiment is as follows: Before use, first check the charge level of the energy storage battery 10 and the status of the rotating nozzle 2. Once everything is normal, the water supply pipe is connected to the rear end of the support spindle 1. The rotating sleeve 73 is rotated according to the inner diameter of the pipe to be cleaned to adjust the distance between each lateral support rod 3 and the support spindle 1 to the pipe to be cleaned. After the device is placed in the pipe, the water supply function of the water supply pipe is activated, and the wheel motors 42 in the multiple first rollers 4 at the front end of the support spindle 1 are activated. Once activated, the multiple wheel motors 42 drive the multiple anti-skid wheels 41 to pull the entire device within the pipe. The water flow from the water supply pipe, which still has a certain pressure, is delivered through the support spindle 1 to the rotating nozzle 2. The water flow's own power causes the rotating nozzle 2 to rotate while spraying water. The operator outside the pipe can use the waterproof camera 9 at the front end of the support spindle 1 to monitor the cleaning status of the pipe in real time and adjust the corresponding parameters according to the specific cleaning situation to ensure the cleaning quality. Compared with the manual method of cleaning pipelines, this application not only reduces the labor intensity of workers and improves cleaning efficiency, but also is adaptable to pipelines of various diameters.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
