DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be described in detail below with reference to the accompanying drawings.

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A high-pressure water jet pipe cleaning device, as Figures 1-4 shown, includes a pipe body frame 1. One end of the pipe body frame 1 is connected to a spray head 2, and the other end of the pipe body frame 1 is connected to a connecting hose 3. A plurality of radially telescopic brackets 4 are provided on the pipe body frame 1.

[0025] Specifically, the pipe body frame 1 can convey water for cleaning, and the pipe body frame 1 is made of rigid material. After being installed with the overall device, it can work stably and reliably without deformation. Further, the pipe body frame 1 is preferably made of stainless steel. The spray head 2 can eject high-speed water flow, thereby generating an impact force to remove dirt and attachments from the inner wall of the pipeline. Through the connecting hose 3, it can be easily bent and extended into the pipe, increasing the flexibility and convenience of cleaning. Through the radially telescopic bracket 4, the width of the bracket in the radial direction can be adjusted, so as to match the inner diameter of the pipe, so that the spray head 2 is located in the middle of the pipe, ensuring that the water jet is evenly distributed to all parts of the inner wall of the pipeline, avoiding the occurrence of cleaning dead angles or uneven cleaning. At the same time, the radially telescopic bracket 4 can also support the pipe body frame 1 without manual holding, greatly reducing the labor intensity of the staff.

[0026] As another specific embodiment, a plurality of the radially telescopic brackets 4 are provided, and the plurality of radially telescopic brackets 4 are evenly spaced along the circumferential direction. The stability of supporting the pipe body frame 1 can be increased through a plurality of brackets.

[0027] As another specific embodiment, the radially telescopic bracket 4 includes three. Three points can determine a circle, so the three-point support can provide a very stable support surface in the pipe, effectively preventing tilting and shaking, and ensuring the stability of the structure.

[0028] As another specific embodiment, the radially telescopic bracket 4 includes a first rod 41 and a second rod 42 whose outer ends are hinged. The inner ends of the first rod 41 and the second rod 42 are hinged to the pipe body frame 1, and the inner end of the first rod 41 is slidably hinged to the pipe body frame 1 along the axial direction of the pipe body frame 1. A triangular structure is formed among the first rod 41, the second rod 42 and the pipe body frame 1. By extending or shortening one side of the triangle, the height of the radially telescopic bracket 4 can be changed, so that the outer circumference of the pipe cleaning device can be expanded or reduced to contact the inner wall of the pipe to cooperate with pipes to be cleaned with different pipe diameters. Further, the inner ends and outer ends of the first rod 41 and the second rod 42 refer to the inside and outside along the radial direction.

[0029] As another specific embodiment, a guiding groove 11 extending axially is provided on the pipe body frame 1, and the inner end of the first support rod 41 is slidably disposed in the guiding groove 11. The guiding groove 11 can ensure that the inner end of the first support rod 41 moves axially, prevent deviation or sway in other directions, ensure the accuracy of adjustment, and ensure the structural stability.

[0030] As another specific embodiment, the radially telescopic support 4 further includes a balance support rod 43 arranged axially. The outer ends of the first support rod 41 and the second support rod 42 are also hinged to the middle of the balance support rod 43. A third support rod 44 is also hinged between the balance support rod 43 and the pipe body frame 1. The third support rod 44 is arranged on the side of the second support rod 42 and is parallel to the second support rod 42. The balance support rod 43 can change the single-point contact between the first support rod 41, the second support rod 42 and the pipeline into multi-point contact or line contact, thereby improving the stability of the radially telescopic support 4 and preventing the pigging device from tilting. The third support rod 44 can increase the control points of the balance support rod 43. The third support rod 44 is parallel to the second support rod 42. According to the principle of two points determining a line, it can ensure that the balance support rod 43 is parallel to the axis. Further, the second support rod 42 and the third support rod 44 are connected to the pipe body frame 1 through a rotating support; the first support rod 41 is arranged in the guiding groove 11 through a sliding support.

[0031] As another specific embodiment, a pulley 45 is provided on the radially telescopic support 4. When the pigging device is working, the pulley 45 can reduce the friction between the radially telescopic support 4 and the inside of the pipe, so that the pigging device can move along the axis for cleaning without causing wear to the inner wall of the pipeline, and at the same time can ensure smooth movement. Further, when the radially telescopic support 4 only has the first support rod 41 and the second support rod 42, the pulley 45 is arranged at the hinge of the first support rod 41 and the second support rod 42; when the radially telescopic support 4 further includes a balance support rod 43 and a third support rod 44, the pulley 45 is arranged at the front and rear ends of the balance support rod 43.

[0032] As another specific embodiment, a plurality of nozzles 21 are circumferentially distributed on the spray head 2. The plurality of nozzles 21 can ensure that all parts of the inner wall of the pipeline can be fully cleaned, reduce the cleaning dead angle, and improve the cleaning quality.

[0033] As another specific embodiment, the spray head 2 is rotatably arranged on the pipe body frame 1 in the circumferential direction. Rotating the spray head 2 can perform 360-degree spraying in the pipeline to ensure that every part of the inner wall of the pipeline can be fully cleaned by the high-pressure water jet, so as to achieve an all-round cleaning effect.

[0034] As another specific embodiment, an annular baffle 22 is provided between the nozzle 2 and the pipe support 1. The annular baffle 22 can prevent the high-pressure water jet from recoiling onto the pipe support 1, thereby affecting the stability of the pigging device; at the same time, the baffle can facilitate the docking of the pipe support 1.

[0035] The working process of a high-pressure water jet pigging device provided in this embodiment is as follows:

[0036] Connect the connecting hose 3 to the pipe support 1 through a buckle. Before removing the dirt on the inner wall of the pipeline, measure the inner diameter of the pipeline. At the same time, move the 3 sets of sliding supports to drive the first support rod 41 to extend. The retraction or expansion of the first support rod 41 drives the balance support rod 43 to approach or move away from the pipe support 1, so as to meet the requirements of the pipeline inner diameter, and the removal of residual dirt on the inner walls of different pipe diameters within a certain size range can be realized. The pulley 45 moves from the pipe orifice to the deep part of the pipeline, thereby driving the 3 sets of rotating nozzles 21 to clean the inner wall of the pipeline. High-pressure water enters the interior of the pipe support 1 from the connecting hose 3, and the high-pressure water is sprayed onto the inner wall of the pipeline through the nozzle 21 to clean the dirt on the inner wall of the pipeline.

[0037] This device is easy to use, saves the materials and time for making different pigging devices for different pipe diameters, and avoids the problems that mechanical cleaning is likely to leave residual particles and dirt is not easy to discharge, and chemical cleaning is likely to cause environmental pollution and is costly. It reduces the manual intensity of removing residual dirt on the inner walls of large-diameter long-distance pipelines, and at the same time is easy to carry and convenient to adjust. This device has been well verified in terms of on-site technology, economy and social safety.
