Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe detection, in particular to a device for detecting damaged parts of PE pipes. Background Art

[0002] PE pipes are steadily developing in China's municipal pipe market, with PE, PP-R, and UPVC all enjoying significant market share. PE pipes, however, are particularly noteworthy for their robust growth. PE pipes are used in a wide range of applications, with water supply and gas pipes being the two largest markets. PE resin is formed by the polymerization of ethylene monomer. Different polymerization conditions, such as pressure and temperature, produce resins of varying densities, resulting in high-density polyethylene (HDPE), medium-density polyethylene (MDPE), and low-density polyethylene (LDPE). When processing different types of PE pipes, different resin grades are selected based on their application, and the requirements for extruders and molds also vary.

[0003] PE pipes inevitably break over extended periods of use. Failure to promptly inspect and repair these leaks not only wastes resources but also results in significant economic losses. However, due to the length of the pipeline, manual inspection of the damaged PE pipes is time-consuming and inefficient. Therefore, a device for detecting PE pipe damage is proposed.

[0023] Figure 1-Figure 5The invention shows a device for detecting damaged parts of PE pipes, which includes a detection vehicle body 1. A symmetrically distributed contraction mechanism 2 is provided on both sides of the detection vehicle body 1. A secondary dynamic roller 3 is provided on the contraction mechanism 2. A mounting plate 4 is provided at one end of the vehicle body 1. A connecting seat 6 is provided on the mounting plate 4. A fixing bolt 5 and a fixing arm 7 are provided on the connecting seat 6. The bottom end of the fixing arm 7 is rotatably connected to the connecting seat 6 through the fixing bolt 5. A rotating arm 8 is provided at the top of the fixed arm 7. A rotating shaft 11 is provided at the bottom end of the rotating arm 8. Active rollers 10 are provided at both ends of the rotating shaft 11. A power mechanism 9 for driving the rotating shaft 11 to rotate is provided on the rotating arm 8.

[0024] like Figure 2 As shown, the function of the retraction mechanism 2 is to ensure that the detection vehicle body 1 does not deflect while traveling in the pipeline, thereby preventing the detection effect from being affected, while also better ensuring the stability of the detection vehicle body 1. The retraction mechanism 2 includes: retraction cylinders 21 provided on both sides of the detection vehicle body 1, springs 22 provided inside the retraction cylinders 21, and retraction rods 23 provided on the retraction cylinders 21. One end of the retraction rod 23 is positioned inside the retraction cylinder 21 and is slidably connected to the retraction cylinder 21. The other end of the retraction rod 23 is fixedly connected to a connecting block 24.

[0025] The secondary roller 23 is connected to the connecting block 24 via a rotation axis.

[0026] In this embodiment, the bottom end of the fixed arm 7 is fixedly connected to the fixing bolt 5, which is rotatably connected to the connecting base 6. The top end of the fixed arm 7 is rotatably connected to the rotating arm 8. When the fixing bolt 5 is rotated, the fixed arm 7 rotates on the connecting base 6 to adjust the horizontal angle of the fixed arm 7. After adjustment, the fixing bolt 5 is secured with a nut to prevent the fixed arm 7 from rotating while the detection vehicle 1 is moving.

[0027] In this embodiment, a telescopic rod 16 is provided on the fixed arm 7, and a slide groove 18 is provided on the bottom surface of the rotatable arm 8. A slider 17 is provided within the slide groove 18. The output end of the telescopic rod 16 is connected to the rotating shaft of the slider 17, and the slider 17 is slidably connected to the slide groove 18. When the telescopic rod 16 pushes the slider 17 to move in the slide groove 18, the rotatable arm 8 also rotates accordingly, and the angle between the rotatable arm 8 and the fixed arm 7 increases. Otherwise, the angle decreases.

[0028] It is particularly important to note that when the telescopic rod 16 pushes the pivot arm 8, the angle between the pivot arm 8 and the fixed arm 7 increases, raising the level of the driving roller 10. When the telescopic rod 16 retracts the pivot arm 8, the angle between the pivot arm 8 and the fixed arm 7 decreases, lowering the level of the driving roller 10. The primary purpose of adjusting the level of the driving roller 10 is to ensure close contact between the driving roller 10 and the pipeline, thereby propelling the inspection vehicle 1 within the pipeline. Similarly, adjusting the angle between the fixed arm 7 and the bottom surface can also adjust the level of the driving roller 10, except that the fixed arm 7 determines the upper and lower limits of the driving roller 10.

[0029] like Figure 3 As shown, the power mechanism 9 is a component that provides power for the active roller 10. The power mechanism 9 includes: a servo motor 91 arranged on the rotating arm 8, a first transmission wheel 93 arranged on the output end of the servo motor 91, a transmission belt 92 arranged on the first transmission wheel 93, and a second transmission wheel 94 arranged on the transmission shaft 11. The first transmission wheel 93 is connected to the second transmission wheel 94 through the transmission belt 92.

[0030] In this embodiment, a first panoramic camera 12 is provided on the upper surface of the inspection vehicle 1, and a second panoramic camera 13 is provided on the lower surface of the inspection vehicle 1. The first panoramic camera 12 and the second panoramic camera 13 can divide the situation inside the pipeline into two perspectives to facilitate observation by the staff.

[0031] In this embodiment, a controller 14 and a power supply 15 are provided inside the detection vehicle body 1 . The power supply 15 , the servo motor 91 , the telescopic rod 16 , the first panoramic camera 12 , and the second panoramic camera 13 are all electrically connected to the controller 14 .

[0032] The working principle of the PE pipe damage detection equipment is as follows:

[0033] During actual use, the active roller 10 is driven to rotate by the power mechanism 9. When the active roller 10 contacts the pipeline, it pushes the inspection vehicle 1 to move within the pipeline. As the inspection vehicle 1 moves within the pipeline, the first panoramic camera 12 and the second panoramic camera 13 on the inspection vehicle 1 record the situation within the pipeline. The video is uploaded to the cloud via the controller 14 for external feedback, allowing staff to observe the real-time situation within the pipeline and determine the location of the damage. At the same time, to reduce friction between the inspection vehicle 1 and the pipeline and enable the inspection vehicle 1 to move more securely within the pipeline, a retraction mechanism 2 is provided on both sides of the inspection vehicle 1. The retraction mechanism 2 is further provided with secondary rollers 3, which allow the inspection vehicle 1 to contact the pipeline through the secondary rollers 3.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
