Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a gas-liquid two-phase pulse device for pipeline cleaning. Background Technology

[0002] In existing technologies, pipe cleaning refers to the technical process of removing dirt from the inner surface of pipes using chemical or physical methods, restoring the surface of the pipe material itself, and forming a protective layer to extend the service life of the pipe. It mainly includes various methods such as high-pressure water jet cleaning, mechanical dredging, robot inspection, and winch dredging.

[0003] A search revealed a Chinese patent application with patent number 202320833218.X, which discloses an air-water pulse cleaning device, including a liftable loading base and an air-water pulse nozzle connected to an air-water pulse supply source; the middle part of the nozzle body is hinged to the loading base at a fixed axis, and one end of the nozzle body is provided with a spray nozzle that can swing up and down around the hinge axis; the nozzle body is provided with an upper handle and a lower handle; the upper handle, lower handle, and hinge axis are all connected to the same position along the length of the nozzle body; the other end of the nozzle body is provided with a nozzle tail handle that can be locked to the loading base at multiple angles.

[0004] The aforementioned patent has the following shortcomings: The air-water pulse cleaning device in the above-mentioned apparatus is a technology that is gradually expanding in the field of pipeline cleaning. This device uses an air-water pulse nozzle to spray cleaning media and uses the upper handle, lower handle and hinge shaft to reduce the impact of the reaction force generated by the air-water pulse nozzle. However, it still requires manual control of the spray direction of the air-water pulse nozzle. The pipeline cleaning time is relatively long, and it is relatively laborious to always manually control the spray direction, which is not conducive to the continuous progress of pipeline cleaning work. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas-liquid two-phase pulse device for pipeline cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas-liquid two-phase pulse device for pipeline cleaning, comprising:

[0008] Air-water pulse nozzle, which is used to spray pulsed water to clean pipes, and has a rotating mounting plate at the bottom;

[0009] An electric lifting rod has a lifting connecting plate fixedly installed at the top of its telescopic end. A rotating positioning column is integrally formed at the top of the lifting connecting plate. A rotating sleeve is rotatably sleeved on the outer wall of the rotating positioning column. The rotating sleeve is welded to the lower surface of the rotating mounting plate.

[0010] A retaining ring is fixedly sleeved on the outer wall of the tail end of the air-water pulse nozzle, and a rotating connecting seat two is fixedly connected to the bottom end. A rotating connecting head is rotatably installed inside the rotating connecting seat two. An electric telescopic rod is fixedly connected to one side of the rotating connecting head. A rotating connecting seat one is rotatably installed at the tail end of the electric telescopic rod. The rotating connecting seat one is fixedly connected to the rotating mounting plate.

[0011] As a further improvement of this utility model: two rotating support arms are fixedly connected to the upper surface of the lifting connecting plate, and a mounting bracket is rotatably installed at the top between the two rotating support arms.

[0012] As a further embodiment of this utility model: a fixed upper bracket is fixedly installed on the top of the lower mounting bracket, and the air-water pulse nozzle is fixedly installed between the fixed upper bracket and the lower mounting bracket.

[0013] As a further improvement of this utility model: the tail ends of the fixed upper card seat and the mounting lower card seat are both fixedly connected to limit cards, and multiple buffer springs are fixedly installed at equal intervals on one side of the limit cards, and a buffer pad is fixedly installed on one end of each buffer spring.

[0014] As a further embodiment of this utility model: a positioning connecting plate is provided on the lower surface of the lifting connecting plate, and a plurality of supporting connecting columns are fixedly installed on the lower surface of the positioning connecting plate, and a movable base is fixedly installed at the bottom end of the supporting connecting columns.

[0015] As a further improvement of this utility model: a controller is fixedly installed at the top center of the mobile base, and the electric lifting rod is fixedly installed at one end of the top of the mobile base.

[0016] As a further embodiment of this utility model: a worm gear ring is fixedly sleeved on the outer wall of the rotating sleeve, and a driving worm is meshed with the outer wall of the worm gear ring.

[0017] As a further improvement of this utility model: both ends of the drive worm are rotatably mounted with worm arms, and the worm arms are fixedly mounted on the upper surface of the lifting connecting plate.

[0018] Compared with the prior art, this utility model provides a gas-liquid two-phase pulse device for pipeline cleaning, which has the following beneficial effects:

[0019] This application perfectly combines flexible multi-dimensional positioning and aiming capabilities with a carefully designed rigid support, stable structure, and buffer mechanism, enabling operators to quickly and accurately align the nozzle with the pipeline inlet. It also maintains the stability and positioning accuracy of the entire device when subjected to strong gas-liquid pulse jet recoil force, ensuring efficient and safe pipeline cleaning operations.

[0020] This application involves installing a lower mounting bracket and fixing a limiting plate, a buffer spring, and a buffer pad at the end of the upper mounting bracket, which are then inserted into the nozzle mating groove. This ingenious mechanism acts like a "suspended" system, allowing the nozzle to generate slight elastic movement under the action of jet recoil force. The spring absorbs and dissipates energy, significantly reducing the peak force transmitted to the support structure from the recoil force.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
