Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a plastic pipeline sealing inspection device. Background Technology

[0002] Pipeline sealing testing devices are used to inspect the sealing performance of pipe joints, welds, and other components. Through methods such as air pressure testing, water pressure testing, and ultrasonic testing, they identify leaks and ensure safe pipeline transportation. Plastic pipe sealing testing devices are used to test the sealing performance of plastic pipes. These devices are suitable for water supply and drainage, gas transmission, chemical industries, and other fields. They can perform sealing tests on plastic pipes during production, installation, and use, ensuring pipeline safety and preventing leaks that could lead to resource waste, safety accidents, and environmental pollution. They can adapt to different media transportation needs, have a long service life, and low maintenance costs.

[0003] In existing technologies, some plastic pipe sealing detection devices utilize methods such as water pressure testing, air pressure testing, and soap water testing. The water pressure testing method involves injecting water into the pipe and pressurizing it, observing pressure changes and whether there is water leakage on the pipe surface. The air pressure testing method is similar, except that the water is replaced with gas. The soap water testing method involves introducing pressurized gas into the pipe, applying soap water to suspected leak points such as pipe joints, and observing whether bubbles are generated. These methods are widely used in industries such as pipeline engineering, automobile manufacturing, medical devices, and food packaging, and can accurately identify minute leaks, ensuring the safety and stable performance of equipment and products.

[0004] However, in the existing technology, some plastic pipe sealing detection devices rely on manual operation and observation. When detecting plastic pipes of different diameters and wall thicknesses, the clamps need to be changed frequently, which not only prolongs the detection preparation time, but also easily leads to additional leakage points during sealing detection due to clamp disassembly and assembly errors, affecting the accuracy of the detection results. Furthermore, the detection head is difficult to adapt to plastic pipes of different sizes. Therefore, a plastic pipe sealing detection device is proposed to solve the above problems.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of a plastic pipe sealing testing device, comprising a testing equipment body 1. The testing equipment body 1 serves as the core load-bearing component of the entire device, providing a stable operating platform and power support for sealing testing. A gas supply pipe 4 is fixedly connected inside the testing equipment body 1. The gas supply pipe 4 stably delivers the testing gas generated inside the testing equipment body 1 to the plastic pipe to be tested, ensuring sealing and stability during gas transmission. A quick-release mechanism 5 is fixedly connected to the other end of the gas supply pipe 4. The quick-release mechanism 5 enables rapid connection and disassembly between the gas supply pipe 4 and the plastic pipe to be tested, significantly shortening the assembly and disassembly time of the device and improving testing efficiency. A hidden carrying component 6 is provided inside the testing equipment body 1, which does not affect the testing equipment. Under the premise of overall structural stability of the main body 1, the device is provided with a convenient way to carry it, making it easy for operators to move the device. When not in use, it can be stored and hidden to ensure the cleanliness of the device's appearance. The quick-release mechanism 5 includes a docking component 51, which serves as the fixed connection part of the quick-release mechanism 5. It is used to stably connect with the gas supply pipe 4 and provides precise docking guidance and limiting support for the embedded component 52. The docking component 51 is externally fixedly connected to the outside of the gas supply pipe 4 to ensure a firm connection between the docking component 51 and the gas supply pipe 4 without the risk of gas leakage. The embedded component 52 is slidably connected inside the docking component 51. The embedded component 52 can slide flexibly inside the docking component 51 to achieve quick docking with the plastic pipe to be tested. At the same time, through cooperation with the docking component 51, it ensures the sealing effect after connection.

[0026] The docking assembly 51 includes a connecting pipe a511, which provides a smooth channel for the sliding of the embedded assembly 52 and ensures the stability of gas transmission within the pipe. The connecting pipe a511 is externally fixedly connected to the outside of the gas transmission pipe 4. Multiple limiting sliding posts 512 are slidably connected internally to the connecting pipe a511. These limiting sliding posts 512 are evenly distributed along the circumference of the connecting pipe a511, precisely limiting the sliding trajectory of the embedded assembly 52 and preventing displacement during sliding. A limiting ring 515 is externally fixedly connected to the connecting pipe a511, which is used to adjust the sliding sleeve 513. The sliding stroke is limited to prevent the sliding sleeve 513 from sliding excessively under the action of the spring 514, and to ensure the coordination of the actions of each component of the quick release mechanism 5. The external sliding connection of the connecting tube a511 is a sliding sleeve 513. The sliding sleeve 513 can slide flexibly outside the connecting tube a511. Through the sliding action, it pushes the limiting slide column 512 to realize the clamping and loosening of the embedded component 52. The external of the sliding sleeve 513 is provided with a spring 514. The spring 514 can provide a continuous elastic force to the sliding sleeve 513, so that the sliding sleeve 513 remains stable when it is not subjected to external force, and ensures the firmness of the connection between the embedded component 52 and the docking component 51.

[0027] The embedded component 52 includes an embedded tube 521, the outer diameter of which matches the inner diameter of the connecting tube a511, ensuring the sealing and smooth sliding of the embedded tube 521 inside the connecting tube a511. The external part of the embedded tube 521 is slidably connected to the inside of the connecting tube a511. Through precise matching with the connecting tube a511, stable gas transmission and sealing of the connection are achieved. A limiting protrusion 522 is fixedly connected to the external part of the embedded tube 521. The limiting protrusion 522 adopts an annular protrusion structure and works in conjunction with the limiting slide post 512 to further limit the sliding range of the embedded component 52 within the connecting tube a511, while enhancing the connection strength between the two and preventing the embedded component 52 from accidentally falling off during the testing process. A clearance recess is provided inside the embedded tube 521. The groove 523 is designed to match the size of the limiting slide post 512, providing sliding space for the limiting slide post 512. This allows the embedded component 52 to be smoothly inserted into and removed from the docking component 51, ensuring the convenience of the quick-release mechanism 5. A plastic tube connecting pipe 524 is fixedly connected to the outer side of the embedded tube 521. The inner diameter of the plastic tube connecting pipe 524 can be adapted to the outer diameter of the plastic pipe to be tested, enabling a tight connection with plastic pipes of different specifications. A sealing gasket 525 is fixedly connected inside the plastic tube connecting pipe 524. The sealing gasket 525 can fill the gap between the plastic tube connecting pipe 524 and the plastic pipe to be tested, greatly enhancing the sealing of the connection and preventing the test gas from leaking from the gap, thus ensuring the accuracy of the sealing test results.

[0028] The outer side of the sliding sleeve 513 is slidably connected to the outside of the limiting ring 515. The limiting ring 515 prevents the sliding sleeve 513 from detaching from the connecting tube a511 under the elastic force of the spring 514, ensuring the structural integrity of the quick-release mechanism 5. The other end of the spring 514 is fixedly connected to the outside of the connecting tube a511. By fixing both ends to the sliding sleeve 513 and the connecting tube a511 respectively, the spring 514 can stably provide elastic force to the sliding sleeve 513, ensuring the reliable operation of the sliding sleeve 513. The outer side of the limiting protrusion 522 is slidably connected to the outside of multiple limiting slide posts 512. The limiting slide posts 512 and the limiting protrusion 522 are connected to the outside of the limiting protrusion 515. The sliding fit of 22 enables precise guidance of the embedded component 52, preventing the embedded component 52 from rotating or shifting within the connecting tube a511. The external sliding connection of the limiting protrusion 522 is inside the connecting tube a511, further enhancing the sealing between the embedded component 52 and the connecting tube a511 and preventing the detection gas from leaking from the fit gap between the two. The internal sliding connection of the clearance groove 523 is to the external of multiple limiting slide pins 512. When the embedded component 52 is inserted into the docking component 51, the limiting slide pins 512 can slide within the clearance groove 523, reducing the frictional resistance between the two and making the insertion process of the embedded component 52 smoother.

[0029] Reference Figure 1 , Figure 2 and Figure 4The concealed carrying component 6 includes a slide 61, the size of which matches the dimensions of the handle 65 and the fixing plate 64, providing storage space for the handle 65 and the fixing plate 64. This ensures that the components can be completely hidden inside the main body 1 of the detection device when the carrying function is not in use. The exterior of the slide 61 is located inside the main body 1 of the detection device, ensuring the overall aesthetics and structural stability of the device. Magnets 62, made of strong magnetic material, are fixedly connected to both sides inside the slide 61. These magnets can magnetically attract iron blocks 66 to fix the handle 65 in its retracted state. A shaft 63 is rotatably connected inside the slide 61, providing support for the rotation of the fixing plate 64 and the handle 65, ensuring smoothness and stability during rotation. The fixing plate 64 is fixedly connected to the exterior of the shaft 63. The fixing plate 64 is used to connect the shaft 63 and the handle 65, enhancing the connection strength between the handle 65 and the shaft 63. The handle 65 is fixedly connected to the outside of the fixing plate 64. The handle 65 adopts an ergonomic design to facilitate the operator's grip and reduce hand fatigue when carrying the device. Iron blocks 66 are fixedly connected to both sides of the outside of the handle 65. The iron blocks 66 can magnetically attract the magnet 62. When the handle 65 is stored in the slide groove 61, the handle 65 is fixed in the slide groove 61 by the attraction between the iron blocks 66 and the magnet 62, preventing the handle 65 from accidentally popping out during the movement of the device. The outside of the iron blocks 66 is slidably connected to the outside of the magnet 62, ensuring that the iron blocks 66 can smoothly cooperate with the magnet 62 during the rotation, storage and unfolding of the handle 65, without affecting the movement of the parts.

[0030] The front of the main body 1 of the testing equipment is equipped with a data display screen 2. The data display screen 2 is a high-definition LCD screen that can display various data during the testing process in real time, such as the test pressure value, test time, leakage amount, etc., so that the operator can intuitively understand the test situation. Multiple adjustment knobs 3 are fixedly connected to the front of the main body 1 of the testing equipment. The multiple adjustment knobs 3 correspond to different test parameter adjustment functions. The operator can accurately set the test parameters by rotating the adjustment knobs 3 to meet the sealing test requirements of different plastic pipes.

[0031] Working principle: When using the plastic pipe sealing test device, the device is first transported to the test site via the handle 65 of the concealed carrying component 6. If it is not necessary to carry it, the handle 65 can be rotated around the shaft 63 into the slide groove 61. The handle 65 is fixed by the attraction between the iron block 66 and the magnet 62. Then, the operator pulls the sliding sleeve 513 of the quick release mechanism 5, which compresses the spring 514 and slides away from the limiting ring 515. At this time, the limiting slide column 512 moves into the connecting pipe a511 under the push of the sliding sleeve 513. Then, the plastic pipe to be tested is inserted into the plastic pipe connecting pipe 524 embedded in the component 52. The sealing gasket 525 in the plastic pipe connecting pipe 524 fits tightly with the plastic pipe, achieving a preliminary seal.

[0032] Push the embedded tube 521 to insert it into the connecting tube a511. The limiting protrusion 522 on the outside of the embedded tube 521 contacts the limiting slide post 512, while the clearance groove 523 provides sliding space for the limiting slide post 512. After the embedded tube 521 is inserted into place, release the sliding sleeve 513. The spring 514 restores its elastic deformation and pushes the sliding sleeve 513 to slide closer to the limiting ring 515. The sliding sleeve 513 drives the limiting slide post 512 to make tight contact with the limiting protrusion 522, realizing a firm connection between the embedded component 52 and the connecting component 51. Finally, set the detection parameters through the adjustment knob 3 on the front of the main body 1 of the detection equipment and start the detection program. The data during the detection process is displayed in real time on the data display screen 2. The operator judges the sealing performance of the plastic pipe based on the data on the data display screen 2.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
