[0002] Pipeline is a device used to transport gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be transported by the fluid's own pressure or gravity. Pipeline has a wide range of uses, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial devices.

[0003] After a pipeline has been used for a period of time, a large amount of scale and stains are likely to accumulate on the inner wall of the pipeline. In order to ensure the normal use of the pipeline, the pipeline needs to be cleaned regularly. The existing pipeline cleaning device needs to be placed in the pipeline when in use. Due to the large number of pipeline models and different diameters, it is difficult to ensure that the cleaning device is located exactly in the middle of the pipeline, and the cleaning effect is difficult to guarantee. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that it is difficult to ensure that the pipeline cleaning device is exactly located in the middle of the pipeline and the cleaning effect is difficult to ensure, and proposes an airbag positioning mechanism for pipeline ultrasonic cleaning.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An airbag positioning mechanism for ultrasonic cleaning of pipelines comprises a mounting frame and two symmetrically arranged mounting tubes respectively fixedly connected to the two ends of the mounting frame, wherein the axes of the two mounting tubes are arranged collinearly, and a plurality of circumferentially distributed elastic airbags can be detachably mounted on the two mounting tubes.

[0010] In order to reduce the resistance of the elastic airbag in the cleaning fluid, preferably, the elastic airbag is spherical in shape.

[0011] In order to make the elastic airbag have good elasticity, corrosion resistance and wear resistance, preferably, the elastic airbag is made of fluororubber.

[0012] In order to reduce the friction resistance of the elastic airbag on the pipeline, further, a moving component is provided on the side of the elastic airbag away from the mounting tube, and the moving component is used to reduce the friction resistance of the elastic airbag.

[0013] In order to enable the elastic airbag to move on the inner wall of the pipe through the ball bearings, preferably, the moving component includes a mounting seat fixedly mounted on the outer wall of the elastic airbag, and the ball bearings are mounted on the mounting seat.

[0014] In order to enable the elastic airbags to efficiently support the entire cleaning device, preferably, 3 to 6 elastic airbags are provided on each of the mounting tubes, and the angles between two adjacent elastic airbags are the same.

[0016] Compared with the prior art, the utility model provides an airbag positioning mechanism for pipeline ultrasonic cleaning, which has the following beneficial effects:

[0017] 1. The airbag positioning mechanism for ultrasonic cleaning of pipelines uses an air pump to blow air into the air intake pipe, and all elastic airbags will expand at the same time. When the elastic airbags are pressed against the inner wall of the pipeline, the air supply to the air intake pipe will be stopped. At this time, the ultrasonic transducer will be positioned just in the middle of the pipeline, so that the cleaning device can be conveniently positioned in the middle of the pipeline to ensure the cleaning effect;

[0018] 2. The airbag positioning mechanism for ultrasonic cleaning of pipelines can make the entire cleaning device adapt to pipelines of different diameters through the elastic airbag that can expand and contract freely, making it more flexible to use.

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can conveniently position the cleaning device in the middle of the pipeline to ensure the cleaning effect, and can make the entire cleaning device adapt to pipelines of different diameters, making it more flexible to use.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] Example:

[0028] Reference Figure 1-Figure 4 , an airbag positioning mechanism for ultrasonic cleaning of pipelines, comprising a mounting frame 1 on which an ultrasonic transducer 2 is mounted, the ultrasonic transducer 2 can emit ultrasonic waves through a vibrating head, and also comprising: two symmetrically arranged mounting tubes 3, respectively fixedly connected to the two ends of the mounting frame 1, wherein the axes of the two mounting tubes 3 are arranged in a colinear manner, and a plurality of circumferentially distributed elastic airbags 5 can be detachably mounted on the two mounting tubes 3, the shape of the elastic airbags 5 is spherical, and the number of elastic airbags 5 on each mounting tube 3 is 3-6, and 3 is preferred in the present application, and the angles between two adjacent elastic airbags 5 are the same;

[0029] When in use, the entire cleaning device is placed in the pipeline and filled with cleaning liquid or water, and then the two mounting tubes 3 are blown with air through the air pump. The two mounting tubes 3 will blow air to all the elastic airbags 5 at the same time, and all the elastic airbags 5 will expand at the same time. When the elastic airbags 5 are all pressed against the inner wall of the pipeline, the air supply to the mounting tubes 3 is stopped. At this time, the ultrasonic transducer 2 will be positioned just in the middle of the pipeline, and the cleaning device can be conveniently positioned in the middle of the pipeline to ensure the cleaning effect. Moreover, since the elastic airbag 5 can be elastically expanded and contracted, the entire device can adapt to pipelines of different diameters and is more flexible to use. When taking it out, the mounting tube 3 is made to discharge the gas in the elastic airbag 5, and the elastic airbag 5 is shrunk and reset, and the entire device can be easily taken out.

[0030] An air intake pipe 8 is fixedly connected to the axial end of one of the mounting tubes 3. The air intake pipe 8 is a flexible rubber tube. The two mounting tubes 3 are connected by a connecting tube 10. When in use, the flexible air intake pipe 8 can extend out of the pipeline. When the entire cleaning device needs to be adjusted, the air intake pipe 8 can be pulled or pushed, thereby facilitating the movement of the entire cleaning device. When air is supplied to the mounting tubes 3, air is blown directly into the air intake pipe 8 through an air pump. The air intake pipe 8 will blow air into one of the mounting tubes 3, and the mounting tube 3 will blow air into the other mounting tube 3 through the connecting tube 10. The two mounting tubes 3 will blow air into all the elastic airbags 5 at the same time.

[0031] A connecting tube 4 is fixedly connected to the outer wall of the mounting tube 3, and a short tube 6 connected thereto is fixedly connected to the elastic airbag 5. The end of the short tube 6 is threadedly connected to the end of the connecting tube 4. When the elastic airbag 5 needs to be disassembled, the short tube 6 is rotated to unscrew it from the connecting tube 4, and the disassembly of the elastic airbag 5 can be completed, making the disassembly and replacement of the elastic airbag 5 very convenient and efficient.

[0032] The elastic airbag 5 is made of fluororubber, and the elastic airbag 5 made of fluororubber has good wear resistance, corrosion resistance and elasticity.

[0033] A moving component is provided on the side of the elastic airbag 5 away from the mounting tube 3, and the moving component is used to reduce the friction resistance of the elastic airbag 5. The moving component includes a mounting seat 7 fixedly mounted on the outer wall of the elastic airbag 5, and a ball 9 is mounted on the mounting seat 7. When the entire cleaning device is pushed to move in the pipeline, the elastic airbag 5 can move on the inner wall of the pipeline through the ball 9, thereby preventing the inner wall of the pipeline from directly causing wear to the elastic airbag 5, thereby effectively protecting the elastic airbag 5.

[0034] A mounting plate 11 is fixedly connected to the mounting tube 3, and the mounting tube 3 is fixedly connected to the mounting frame 1 through the mounting plate 11. The mounting plate 11 is fixedly connected to the mounting frame 1 through screws. When the mounting tube 3 needs to be disassembled, the screws on the mounting plate 11 can be unscrewed, thereby facilitating the disassembly and installation of the mounting tube 3.

[0035] When using the airbag positioning mechanism for ultrasonic cleaning of pipelines, the entire cleaning device is placed in the pipeline, and the pipeline is filled with cleaning liquid or water, and then the air inlet pipe 8 is blown by the air pump, and the air inlet pipe 8 will blow air to one of the mounting tubes 3, and the mounting tube 3 will blow air to the other mounting tube 3 through the connecting tube 10, and the two mounting tubes 3 will blow air to all the elastic airbags 5 at the same time, and all the elastic airbags 5 will expand at the same time. When the elastic airbags 5 are all pressed against the inner wall of the pipeline, the air supply to the air inlet pipe 8 is stopped. At this time, the ultrasonic transducer 2 will be positioned just in the middle of the pipeline, and the cleaning device can be conveniently positioned in the middle of the pipeline to ensure the cleaning effect. In addition, since the elastic airbag 5 can be elastically expanded and contracted, the entire device can adapt to pipelines of different diameters and is more flexible to use. When taking it out, the air inlet pipe 8 is made to discharge the gas in the elastic airbag 5, and the elastic airbag 5 is contracted and reset, and the entire device can be easily taken out.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
