[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0022] Example:

[0023] To address the issues of high cost, complex structure, high failure rate, and high maintenance costs associated with current equipment used for cleaning narrow pipes, we propose a simple pipe cleaning support with a minimal structure that can adapt to pipes of different sizes. The specific solution is as follows:

[0024] like Figure 1-3 As shown, this embodiment provides an adjustable simple pipe cleaning support, including a central pipe support 1, a plug cap 2, a front fixing sleeve 3, a front frame 4, a front top sleeve 5, a spring 6, a rear frame 7, and a rear fixing sleeve 8. The plug cap 2, the front fixing sleeve 3, the front frame 4, the front top sleeve 5, the spring 6, the rear frame 7, and the rear fixing sleeve 8 are sequentially fitted onto the outside of the central pipe support 1 from front to back. The plug cap 2 has inclined high-pressure nozzles 201 evenly spaced around its center towards the rear frame 7. In order to allow the high-pressure water flow to turn more smoothly inside the plug cap 2 and be discharged through the high-pressure nozzles, the cavity inside the front end of the plug cap 2 is hemispherical, and the high-pressure nozzles 201 are inclined at an angle of 45-60 degrees.

[0025] Specifically, the front and rear ends of the central pipe frame 1 are threaded. The plug cap 2 and the front fixing sleeve 3 are threadedly assembled at the front end of the central pipe frame 1. The plug cap 2 is used to block the water outlet at the front end of the central pipe frame 1, forcing high-pressure water to spray out from the high-pressure nozzle 201, forming a backward spraying effect, thereby generating forward thrust on the entire device. This allows the plug cap 2 to provide forward thrust for the device while also having the effect of pipe flushing and cleaning. The main function of the front fixing sleeve 3 is to position the front frame 4 and prevent the front frame 4 from detaching from the front end of the central pipe frame 1.

[0026] The rear fixing sleeve 8 is threaded onto the tail end of the central pipe frame 1. The front frame 4 and the rear frame 7 are slidably fitted with the central pipe frame 1. The front top sleeve 5 and the spring 6 are located between the front frame 4 and the rear frame 7. Several support leg assemblies 10 are arranged at equal intervals around the circumference between the front frame 4 and the rear frame 7. Each support leg assembly 10 includes a front cross arm 101 and a rear cross arm 102. The front cross arm 101 and the rear cross arm 102 are the same size and shape. The middle of the front cross arm 101 and the rear cross arm 102 are hinged by a pin 103. Rollers 104 are rotatably installed at the tail ends of the front cross arm 101 and the rear cross arm 102. The front ends of the front cross arm 101 and the rear cross arm 102 are hinged with the corresponding front frame 4 and the rear frame 7. By adjusting the position of the rear fixing sleeve 8 on the central pipe frame 1, the opening and closing degree of the support leg assembly 10 can be adjusted in conjunction with the spring 6 and the front top sleeve 5, so that the device can adapt to pipes of different sizes.

[0027] To facilitate connection with the water supply system, a 360-degree rotatable quick-connect fitting 9 is threaded onto the tail end of the central pipe rack 1. This 360-degree rotatable quick-connect fitting 9 is a female connector, and the operator only needs to plug the male connector installed at the front end of the high-pressure water supply pipe into the 360-degree rotatable quick-connect fitting 9 to complete the water supply connection.

[0028] The entire device has a simple structure, adopts a purely mechanical design, has low manufacturing cost, is durable and has a low failure rate, and is easier to maintain. After connecting the water supply system to the device, the device is placed in the corresponding pipe to be cleaned, the water supply system is started, and high-pressure water is delivered into the device. The operator only needs to pull the device from behind by pulling the water supply pipe or connecting a traction rope to control its forward speed.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
