Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and specifically relates to a ground pipeline leakage detection device. Background Technique

[0002] A pipeline is a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. During the use of pipelines, leakage detection needs to be carried out regularly to reduce the losses caused by pipeline leakage.

[0003] Existing ground pipeline leakage detection equipment usually uses a thermal imager for detection, specifically:

[0004] A thermal imager is a device based on the principle of infrared radiation that can display the heat differences of different objects or different parts of an object. In detecting pipeline leakage, a thermal imager is particularly useful, especially in the following scenarios:

[0005] Detecting hidden leaks: In areas that are difficult to directly observe, such as under walls, floors, or roofs, a thermal imager can detect the heat differences caused by water evaporation, thereby indicating potential leakage locations;

[0006] Quick positioning: Compared with traditional leakage detection methods, a thermal imager can quickly scan pipelines and immediately display possible leakage locations;

[0007] When existing pipeline leakage detection is carried out, due to the long laying distance of common ground pipelines, detection personnel need to use a handheld thermal imager for mobile detection. The following problems will occur during this process, which bring inconvenience to pipeline detection:

[0008] First, when the position of the ground pipeline is relatively low, in order to improve the detection accuracy, detection personnel need to squat down to bring the thermal imaging probe closer to the pipeline for detection. In this way, when the pipeline is long, detection personnel need to keep squatting and moving forward for a long time, which is very easy to get tired and increases the work intensity;

[0009] Second, keeping squatting and moving forward for a long time results in slow movement and low detection efficiency. Therefore, considering the above two problems, we need to propose a ground pipeline leakage detection device. Content of the Utility Model

[0010] The purpose of the utility model is to provide a ground pipeline leakage detection device, which has the advantages of improving the detection effort and efficiency, so as to solve the problems raised in the above background technique.

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-6 , the present invention provides a technical solution: a ground pipeline leakage detection device, including a base 1, a thermal imager 2, and a thermal imaging probe 3 connected to the thermal imager 2 through a wire. A first adjustment component for adjusting the height of the thermal imaging probe 3 is installed on the top of the base 1; the first adjustment component includes a support column 6, the support column 6 is installed on the top of the base 1, a fixing seat 7 is provided on the front surface of the support column 6, and a first fixing block 8 and a second fixing block 9 are respectively installed on both sides of the back surface of the fixing seat 7. The inner sides of the first fixing block 8 and the second fixing block 9 are both slidably attached to the surface of the support column 6. By providing the first fixing block 8 and the second fixing block 9, the fixing seat 7 can be preliminarily limited.

[0034] Furthermore, the surface of the first fixing block 8 is threadedly connected with a first screw 10, a first limiting groove 11 is opened on one side of the support column 6 close to the first screw 10, and one end of the first screw 10 extends into the interior of the first limiting groove 11. A limiting block 12 is installed on one side of the second fixing block 9 close to the support column 6, a second limiting groove 13 is opened on the side of the support column 6 away from the first limiting groove 11, and one end of the limiting block 12 slidably extends into the interior of the second limiting groove 13. A first box body 4 is installed on the top of the first adjustment component, and the thermal imager 2 is installed inside the first box body 4; by providing the first box body 4, the thermal imager 2 can be installed and protected.

[0035] Specifically, a second box body 5 is detachably installed at one end of the second adjusting component away from the base 1, and the thermal imaging probe 3 is installed at one end of the second box body 5 away from the second adjusting component; by moving the fixed seat 7 up and down, the first fixing block 8 and the second fixing block 9 move while the fixed seat 7 moves. By setting the limit block 12, the sliding engagement of the limit block 12 with the second limit groove 13 can further limit the fixed seat 7, enabling it to move up and down along the support column 6. While the fixed seat 7 moves, it can drive the second box body 5 and the thermal imaging probe 3 to move up and down through the second adjusting component, adjusting the height of the thermal imaging probe 3, so that the thermal imaging probe 3 can be closer to the ground pipeline, improving the detection accuracy.

[0036] In addition, after moving to the appropriate height, by rotating the first screw rod 10, the friction between the first screw rod 10 and the first limit groove 11 can limit the fixed seat 7, thereby achieving the purpose of limiting and stabilizing the height of the thermal imaging probe 3.

[0037] Furthermore, a second adjusting component for adjusting the lateral position of the thermal imaging probe 3 is installed inside the first adjusting component. The second adjusting component includes a cross bar 14 that slides through the fixed seat 7. A positioning wheel 15 is installed inside the fixed seat 7. Positioning grooves 16 are provided on both the upper and lower sides of the cross bar 14, and the positioning wheel 15 rolls and fits inside the positioning grooves 16. One end of the cross bar 14 is installed with a handle 18. By setting the positioning grooves 16 and the positioning wheel 15, it is convenient for the user to pull the cross bar 14 through the handle 18 and improve the smoothness during pulling.

[0038] Specifically, a second screw rod 17 is threadedly connected to the front surface of the fixed seat 7, and one end of the second screw rod 17 extends into the fixed seat 7 and fits against the surface of the cross bar 14. A vertical rod 19 is installed at the end of the cross bar 14 away from the handle 18. When the cross bar 14 moves, it will drive the vertical rod 19 to move. When the vertical rod 19 moves, it will drive the second box body 5 and the thermal imaging probe 3 to adjust their lateral positions, further adjusting the position of the thermal imaging probe 3 in cooperation with the first adjusting component, maximizing the detection accuracy of the thermal imaging probe 3 for the pipeline.

[0039] In addition, after the lateral distance adjustment is completed, by rotating the second screw rod 17, the friction generated when the second screw rod 17 contacts the cross bar 14 can position the cross bar 14, thereby achieving the positioning of the thermal imaging probe 3.

[0040] It is worth noting that through the settings of the first adjusting component and the second adjusting component, the position of the thermal imaging probe 3 can also be flexibly adjusted according to the actual laying situation of the ground pipeline, improving the adaptability to the environment.

[0041] Among them, a control lever 25 is installed on the top of the base 1 and on the front side of the first box body 4, and shock-absorbing casters 26 are installed at the bottom of the base 1. During use, the user holds the control lever 25 and moves the device along the path of pipeline laying through the shock-absorbing casters 26. During the movement, the leak detection of the pipeline along the way is carried out by the thermal imaging probe 3. Compared with the traditional manual squat-walking detection method, the load is reduced, it is more labor-saving, and the detection speed and efficiency are also improved.

[0042] This embodiment also provides an installation method for the second box body 5. A square rod 20 is installed on one side of the second box body 5. A lead screw 21 is installed at one end of the square rod 20 away from the second box body 5. A through hole is opened inside the vertical rod 19, and a limiting ring 23 is installed inside the through hole. One end of the square rod 20 slidably penetrates through the limiting ring 23. One end of the lead screw 21 penetrates through the vertical rod 19 through the through hole and is threadedly sleeved with a nut sleeve 24. One end of the nut sleeve 24 fits against the surface of the vertical rod 19.

[0043] By providing the limiting ring 23 and the square rod 20, the lead screw 21 will not rotate randomly when passing through the through hole, so that the second box body 5 and the thermal imaging probe 3 can also be stably positioned.

[0044] Among them, a sleeve 27 is installed on one side of the thermal imager 2. The outer sides of the first box body 4 and the second box body 5 are both threadedly connected with third screws 28. After the third screw 28 passes through the first box body 4 or the second box body 5, it is threadedly connected with the inside of the sleeve 27, so as to fix the thermal imager 2 inside the first box body 4 or the second box body 5 and prevent the thermal imager 2 from falling. It is also convenient to take out the thermal imager 2 from the first box body 4 or the second box body 5.

[0045] It should be noted that during the pipeline detection process, when encountering a narrow corner and the first adjustment component and the second adjustment component interfere with the detection of the thermal imaging probe 3 due to environmental restrictions, the thermal imager 2 inside the first box body 4 can be taken out and then installed inside the second box body 5. Then, by rotating the nut sleeve 24, the nut sleeve 24 is separated from the lead screw 21, and at the same time, the second box body 5 is also removed from the vertical rod 19. The nut sleeve 24 is reinstalled and acts as a handle. In this way, the detector can hold the nut sleeve 24 and only carry the second box body 5, the thermal imaging probe 3 and the thermal imager 2 to carry out the pipeline detection work, which can facilitate the detection in the restricted space and improve the applicability of the device.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
