Description

Technical Field

[0001] This utility model relates to a pressure pipeline testing device, specifically a boiler pressure pipeline testing device, and belongs to the technical field of pressure pipeline testing. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace. The hot water or steam produced in the boiler can directly provide the heat energy needed for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers and are mainly used for domestic purposes.

[0003] However, existing boiler pressure pipeline detection devices are generally unable to accurately and quickly determine the location of pipeline leaks when detecting pipeline pressure. Locating the leak point takes a lot of time, resulting in long detection times and low detection efficiency. To address these issues, we provide a boiler pressure pipeline detection device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a boiler pressure pipeline detection device, the specific technical solution of which is as follows:

[0005] A boiler pressure pipeline testing device includes a base plate, a side plate connected to the upper surface of the base plate, a motor connected to the outer surface of the side plate, a rotating rod connected to the output shaft end of the motor, one end of the rotating rod rotating through the outer surface of the side plate, a bracket connected to one end of the rotating rod, a hydraulic rod connected to the outer surface of the bracket, a fixing plate connected to one end of the hydraulic rod, a pipeline body disposed on the outer surface of the fixing plate, and a housing connected to the upper surface of the base plate, the interior of the housing being filled with liquid water.

[0006] Preferably, a rubber ring is connected to the outer surface of the pipe body, and a side cover is slidably connected to the outer surface of the pipe body.

[0007] Preferably, the inner wall of the side cover is provided with a circular groove, the outer surface of the rubber ring is slidably connected to the inner wall of the circular groove, one end of the side cover is fixedly connected to a conveying pipe, and one end of the conveying pipe is fixedly connected to a blower.

[0008] Preferably, a second side plate is connected to the upper surface of the base plate, a connecting plate is connected to the outer surface of the second side plate, and a rotating plate is slidably connected to the outer surface of the connecting plate.

[0009] Preferably, the outer surface of the connecting plate is provided with a sliding groove, the outer surface of the rotating plate is connected with a sliding plate, and the outer surface of the sliding plate is slidably connected to the inner wall of the sliding groove.

[0010] Preferably, a bracket two is connected to the outer surface of the rotating plate, a hydraulic rod two is connected to the outer surface of the bracket two, and a fixing plate two is connected to one end of the hydraulic rod two.

[0011] Preferably, there are two side covers, symmetrically distributed at both ends of the pipe body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This boiler pressure pipeline detection device, through the cooperation of side plate 1, motor, bracket 1, hydraulic rod 1, housing, and liquid water, seals both ends of the pipeline body with side covers, and then fixes the pipeline with fixing plate 1 and fixing plate 2. A part of the pipeline body is immersed in water. Air can be blown into the pipeline body by a blower, thereby changing the atmospheric pressure inside the pipeline. If there is a leak point in the part in contact with the liquid water, continuous water bubbles will appear at the leak point. This solves the problem that existing boiler pressure pipeline detection devices cannot accurately and quickly determine the location of pipeline leaks when detecting pipeline pressure, and the search for leak points takes a lot of time, resulting in long detection time and low detection efficiency.

[0014] 2. This boiler pressure pipeline detection device utilizes the cooperation between a motor, support one, side plate two, a fixed plate, and a rotating plate. The output shaft of the motor drives support one to rotate via a rotating rod. Support one drives the pipeline body to rotate, and the pipeline body drives support two to rotate via fixed plate two. The rotating plate rotates on the outer surface of the fixed plate, allowing the pipeline body to rotate one full turn. This allows for the detection of the entire pipeline body. Moreover, the inspection worker only needs to stand nearby and observe the location of the bubbles to quickly determine the location of the leak. If multiple leak points exist, they can be observed simultaneously, achieving the goals of convenient operation and saving time and effort. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1-5 As shown, a boiler pressure pipeline detection device includes a base plate 1, a side plate 2 connected to the upper surface of the base plate 1, a motor 3 connected to the outer surface of the side plate 2, a rotating rod 4 connected to the output shaft end of the motor 3, the output shaft end of the motor 3 drives the rotating rod 4 to rotate, providing power to the rotating rod 4 for convenient operation.

[0023] One end of the rotating rod 4 rotates through the outer surface of the side plate 2. One end of the rotating rod 4 is connected to the bracket 5. The outer surface of the bracket 5 is connected to the hydraulic rod 6. There are two hydraulic rods 6, which are symmetrically distributed. Each hydraulic rod 6 is an independent entity. When fixing the pipe body 8, the switches of the two hydraulic rods 6 are activated at the same time.

[0024] One end of the hydraulic rod 6 is connected to a fixing plate 7. The outer surface of the fixing plate 7 is provided with a pipe body 8. The upper surface of the base plate 1 is connected to a side plate 16. The outer surface of the side plate 16 is connected to a connecting plate 17. The outer surface of the connecting plate 17 is slidably connected to a rotating plate 18. The pipe body 8 drives the bracket 21 to rotate through the fixing plate 23. The rotating plate 18 will rotate on the outer surface of the connecting plate 17.

[0025] The outer surface of the rotating plate 18 is connected to the bracket 21, and the outer surface of the bracket 21 is connected to the hydraulic rod 22. One end of the hydraulic rod 22 is connected to the fixing plate 23. The hydraulic rod 6 and the hydraulic rod 22 are internally equipped with cylinders, pistons, piston rods and seals. The working principle of the hydraulic rod 6 and the hydraulic rod 22 is based on Pascal's law, that is, the pressure applied to a closed liquid will be evenly transmitted to all parts of the liquid. Through this force transmission method, the hydraulic rod 22 can achieve the support and motion control of the external load. The bracket 5 and the bracket 21 are made of stainless steel to prevent rusting when in contact with water.

[0026] The outer surface of the connecting plate 17 is provided with a groove 19, and the outer surface of the rotating plate 18 is connected with a sliding plate 20. The outer surface of the sliding plate 20 is slidably connected to the inner wall of the groove 19. When the rotating plate 18 rotates on the outer surface of the connecting plate 17, the sliding plate 20 will slide inside the groove 19. The arrangement of the sliding plate 20 and the groove 19 can connect the connecting plate 17 and the rotating plate 18 together, so that they can also rotate relative to each other. The inner wall of the groove 19 is coated with lubricating oil to facilitate the sliding between the sliding plate 20 and the groove 19.

[0027] A rubber ring 11 is connected to the outer surface of the pipe body 8, and a side cover 12 is slidably connected to the outer surface of the pipe body 8. When installing the side cover 12, press the side cover 12 firmly onto one end of the pipe body 8 to install the side cover 12.

[0028] The inner wall of the side cover 12 is provided with a circular groove 13. The outer surface of the rubber ring 11 is slidably connected to the inner wall of the circular groove 13. One end of the side cover 12 is fixedly connected to a conveying pipe 14, and one end of the conveying pipe 14 is fixedly connected to a blower 15. The rubber ring 11 can be precisely locked inside the circular groove 13 to seal the side cover 12 and the pipe body 8 and prevent air leakage.

[0029] There are two side covers 12, symmetrically distributed at both ends of the pipe body 8. The side covers 12 are made of hard plastic sheet. There are two circular grooves 13 inside, which correspond to two rubber rings 11. The upper surface of the bottom plate 1 is connected to the box body 9. The box body 9 is made of transparent plastic sheet, which is made of polycarbonate. It has high transparency, with a light transmittance of over 90%, and strong impact resistance. The location of the air bubbles can be clearly seen. Liquid water 10 is placed inside the box body 9.

[0030] The motor 3, hydraulic rod 6, and hydraulic rod 22 in this application are common electrical and hydraulic devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

[0031] In use, the following steps are taken: The pipe body 8 is sealed at both ends using side covers 12. The rubber ring 11 on the outer surface of the pipe body 8 is inserted into the circular groove 13, forming a sealed space with the two side covers 12 and the pipe body 8. One end of the pipe body 8 is then placed between two fixing plates 7. Hydraulic rods 6 are activated, extending one end of each rod. The two fixing plates 7 move closer together, compressing and fixing the pipe body 8. The other end of the pipe body 8 is then fixed using fixing plate 23. After the pipe body 8 is fixed, a portion of it is immersed in water. Air is then blown into the pipe body 8 through the blower 15 and the conveying pipe 14, thereby... By changing the atmospheric pressure inside the pipe body 8, if there is a leak at the part in contact with liquid water 10, continuous water bubbles will appear at the leak point. The output shaft of motor 3 drives bracket 5 to rotate through rotating rod 4. Bracket 5 drives pipe body 8 to rotate through hydraulic rod 6 and fixed plate 7. Pipe body 8 drives bracket 21 to rotate through fixed plate 23. Rotating plate 18 will rotate on the outer surface of connecting plate 17. At this time, sliding plate 20 will slide on the inner wall of sliding groove 19, so that pipe body 8 can rotate one revolution, thereby allowing the entire pipe body 8 to be inspected. If there are multiple leaks, they can also be observed at the same time, achieving the purpose of convenient operation and saving time and effort.
