Description

Technical Field

[0001] This utility model relates to the field of infrastructure technology, and in particular to a non-contact underground pipeline leakage detection device. Background Technology

[0002] Underground pipes are the main means of water supply for urban and rural life and industry. With the development of the national economy and the improvement of people's living standards, the demand for tap water in cities has risen sharply. The supply of tap water is far from meeting the actual needs. At present, the tap water pipes in use are seriously leaking. According to incomplete statistics, the water loss due to management damage accounts for more than 10% of the total water supply, resulting in a loss of billions of tons of precious tap water every year. This waste of water resources and economic loss is huge and has attracted the attention of urban management departments. Therefore, it is an urgent need for the tap water industry to study leak detection methods and advanced leak detection instruments.

[0003] In existing technologies, when detecting leaks in underground pipelines, to avoid the need for excavation, thermal imagers are typically used to image the overall direction and leakage status of the underground pipelines. Existing thermal imagers mainly consist of three modules: a support, a acquisition probe, and an imaging display screen. To facilitate portability, some thermal imagers have a multi-directionally rotatable adjustable storage structure between the support and the imaging display screen. While this method reduces the size of the thermal imager for portability, some models have a dedicated storage box for the display screen that can be folded up for storage. However, most models only fold up. The former cannot guarantee that dust will accumulate inside the storage box during long-term operation, leading to a short circuit risk when the display screen comes into contact with dust after storage. The latter, by directly exposing the space for transportation, significantly increases the risk of short circuits due to dust contact.

[0004] Therefore, a non-contact underground pipeline leakage detection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a non-contact underground pipeline leakage detection device that can solve the problems of dust accumulation and short circuit risk in the traditional storage box outside the display screen of existing thermal imagers, as well as the pollution problem caused by direct exposure during transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-contact underground pipeline leakage detection device, including a thermal imager, wherein a dustproof self-cleaning mechanism is movably connected to the outer side of the thermal imager, and a convenient replacement mechanism is movably connected to the inner side of the dustproof self-cleaning mechanism.

[0007] The dustproof self-cleaning mechanism includes snap-fit ​​sliders fixedly connected to both sides of the thermal imager. A dust cover is slidably connected to the outer side of the snap-fit ​​slider, and an elastic fixing component is movably connected to the inner side of the snap-fit ​​slider. An arc-shaped extrusion strip is fixedly connected to the inner side of the dust cover, and the arc-shaped extrusion strip is located on the outer side of the elastic fixing component. A convenient replacement mechanism is movably connected to the inner side of the dust cover, and a wiping cotton is movably connected to the inner side of the convenient replacement mechanism.

[0008] Preferably, the convenient replacement mechanism includes a mounting groove formed inside the dust cover, and a mounting slot is formed on the front side of the dust cover.

[0009] Preferably, a support plate is inserted into the front side of the mounting slot, and a cleaning cotton is movably connected to the rear side of the support plate, with the cleaning cotton disposed inside the mounting slot.

[0010] Preferably, the top and bottom of the dust cover are fixedly connected to support blocks, the front side of the support block is fixedly connected to a telescopic column, the front side of the telescopic column is fixedly connected to an elastic pressure plate, the elastic pressure plate is disposed on the front side of the support plate, and the outer side of the telescopic column is fixedly connected to a tension spring.

[0011] Preferably, the elastic fixing component includes a travel groove formed inside the snap-fit ​​slider, and a telescopic compression column is fixedly connected to the inside of the travel groove.

[0012] Preferably, an arc-shaped extrusion block is fixedly connected to the outer side of the telescopic extrusion column, the arc-shaped extrusion block is disposed on the outer side of the arc-shaped extrusion strip, and a compression spring is fixedly connected to the outer side of the telescopic extrusion column.

[0013] Preferably, the front side of the support plate and the outer side of the thermal imager are both fixedly connected to a first positioning magnet.

[0014] Preferably, a second positioning magnet is fixedly connected to the inner side of the snap-fit ​​slider and the inner side of the dust cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application addresses the pain points of traditional thermal imager display storage methods by incorporating a dustproof self-cleaning mechanism. By replacing storage boxes and direct exposure with a dust cover, the display screen is prevented from coming into contact with dust, reducing the risk of short circuits. Secondly, the dust cover uses a triple fixation method of sliding, elastic snap-fit, and magnetic attraction, ensuring a stable installation. It can only be pulled out in the reverse direction, providing better dustproof and stability. Finally, the cleaning cotton inside the dust cover can wipe the display screen during disassembly, keeping the screen clean. It is also reusable, reducing cleaning costs and hassle. In this way, it not only protects the display screen but also assists in cleaning, providing a safer and more convenient solution for the use and carrying of thermal imagers for underground pipeline leakage detection.

[0017] 2. This application simplifies the replacement process of the cleaning cotton by setting up a convenient replacement mechanism. First, remove the support plate, tear off the dirty cleaning cotton and replace it with a new one. Then, pull the elastic pressure plate to store force and insert the support plate back into the slot of the dust cover. After releasing, the spring will rebound and lock it tightly. Pulling in the opposite direction will easily remove it. This ensures that the cleaning cotton can be quickly replaced when it is dirty, avoiding screen contamination. The whole process is tool-free and can be done by hand. At the same time, the elastic structure is stable and there is no need to worry about the support plate falling off during use. This maintains the cleaning function of the dust cover and makes the replacement of consumables more convenient and less costly. Attached Figure Description

[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] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A non-contact underground pipeline leakage detection device includes a thermal imager 1, a dustproof self-cleaning mechanism 2 movably connected to the outside of the thermal imager 1, and a convenient replacement mechanism 3 movably connected to the inside of the dustproof self-cleaning mechanism 2.

[0027] The dustproof self-cleaning mechanism 2 includes a snap-fit ​​slider 21 fixedly connected to both sides of the thermal imager 1. A dust cover 22 is slidably connected to the outer side of the snap-fit ​​slider 21. An elastic fixing component 23 is movably connected to the inner side of the snap-fit ​​slider 21. An arc-shaped extrusion strip 24 is fixedly connected to the inner side of the dust cover 22. The arc-shaped extrusion strip 24 is located on the outer side of the elastic fixing component 23. A convenient replacement mechanism 3 is movably connected to the inner side of the dust cover 22. A wiping cotton 25 is movably connected to the inner side of the convenient replacement mechanism 3.

[0028] In this embodiment: When detecting leaks in underground pipes, to avoid digging up the ground, a thermal imager 1 is typically used to image the direction of the underground pipes and the extent of the leak. Current thermal imagers 1 mainly consist of three modules: a support structure, a data acquisition probe, and an imaging display screen. For portability, some thermal imagers 1 have a multi-directionally rotatable adjustable storage structure between the support structure and the imaging display screen, reducing their size through rotation. However, some models use a dedicated storage box to house the rotated display screen, but after prolonged use, dust easily accumulates in the storage box, posing a short-circuit risk to the display screen. Most models, on the other hand, allow the display screen to be transported exposed to the outside environment, thus increasing the risk of dust exposure. The risk of short circuit is even greater. In this case, align the groove inside the dust cover 22 with the snap-fit ​​slider 21 on the outside of the display screen, and then push it inward to slide and install it. The installation is stable by means of sliding connection, elastic snap-fit ​​and magnetic attraction through the elastic fixing component 23. Moreover, it can only be pulled out in reverse for unidirectional disassembly. In this way, the dust cover 22 can replace the traditional storage box and play a role in dust protection for the display screen, isolating external dust. In addition, during the process of unidirectionally pulling out and disassembling the dust cover 22, the cleaning cotton 25 on the dust cover 22 will quickly slide across the surface of the display screen to wipe the surface of the display screen, complete the auxiliary cleaning, and can be reused until most of the dirt is replaced.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the convenient replacement mechanism 3 includes a mounting groove 31 opened inside the dust cover 22, and a mounting slot 32 opened on the front side of the dust cover 22.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a support plate 33 is inserted into the front side of the mounting slot 32, and a cleaning cotton 25 is movably connected to the rear side of the support plate 33. The cleaning cotton 25 is located inside the mounting slot 31.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the top and bottom of the dust cover 22 are fixedly connected to support blocks 34, the front side of the support block 34 is fixedly connected to a telescopic column 35, the front side of the telescopic column 35 is fixedly connected to an elastic pressure plate 36, the elastic pressure plate 36 is set on the front side of the support plate 33, and the outer side of the telescopic column 35 is fixedly connected to a tension spring 37.

[0032] In this embodiment: Before installing the dust cover 22, the support plate 33 on the outside of the dust cover 22 is removed. There is a cleaning cotton 25 on the inside of the support plate 33 for support. If the cleaning cotton 25 is contaminated, it needs to be replaced by plugging or sticking it. Next, the elastic pressure plate 36 located on the outside of the support plate 33 is pulled. In this way, the telescopic column 35 between the elastic pressure plate 36 and the support block 34 and the tension spring 37 on the outside of the telescopic column 35 will be stretched, thereby accumulating elastic potential energy and maintaining this state. The support plate 33 with the cleaning cotton 25 is inserted into the mounting slot 32 on the outside of the dust cover 22. It is necessary to ensure that the cleaning cotton 25 is just inserted into the mounting groove 31 on the outside of the dust cover 22. Then, the pressure on the elastic pressure plate 36 is released. The elastic pressure plate 36 will be pulled back by the rebound action of the telescopic column 35 and its outer tension spring 37, thereby pressing and limiting the support plate 33. This completes the installation. When disassembling, the reverse steps are followed.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the elastic fixing component 23 includes a travel groove 23a formed inside the snap-fit ​​slider 21, and a telescopic compression column 23b is fixedly connected to the inside of the travel groove 23a.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, an arc-shaped extrusion block 23d is fixedly connected to the outer side of the telescopic extrusion column 23b. The arc-shaped extrusion block 23d is located on the outer side of the arc-shaped extrusion strip 24. A compression spring 23c is fixedly connected to the outer side of the telescopic extrusion column 23b.

[0035] In this embodiment: multiple travel grooves 23a are made on the smoother side of the snap-fit ​​slider 21. Each travel groove 23a contains an elastic structure, which is composed of a telescopic extrusion column 23b with a compression spring 23c on the outside supporting the arc-shaped extrusion block 23d. On the other side opposite the arc-shaped extrusion block 23d, that is, on the inner wall of the dust cover 22, an arc-shaped extrusion strip 24 is fixedly connected. This arc-shaped extrusion strip 24 is a long strip structure composed of multiple protrusions. When the dust cover 22 moves along the snap-fit ​​slider... When block 21 slides inward, the arc-shaped extrusion strip 24 on the inner side of dust cover 22 will extrude the arc-shaped extrusion block 23d, causing the arc-shaped extrusion block 23d to retract into the stroke groove 23a, while simultaneously pressing the telescopic extrusion column 23b and the compression spring 23c on its outer side. After the dust cover 22 slides along the locking slider 21 to the end point and completes the sliding connection, the side of the dust cover 22 with the arc-shaped extrusion strip 24 will achieve elastic locking through the thrust generated by the rebound of the arc-shaped extrusion block 23d in the multiple stroke grooves 23a on the inner side of the locking slider 21.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, the front side of the support plate 33 and the outer side of the thermal imager 1 are both fixedly connected to the first positioning magnet 4.

[0037] Specifically, such as Figure 3 As shown, the inner side of the snap-fit ​​slider 21 and the inner side of the dust cover 22 are both fixedly connected with a second positioning magnet 5.

[0038] In this embodiment: the first positioning magnet 4 can be used to attach the entire structure of the dust cover 22 to the back of the display screen for easy carrying, and the second positioning magnet 5 can stabilize the installation of the dust cover 22 on the display screen.

[0039] Working Principle: When detecting leaks in underground pipelines, to avoid the need for excavation, a thermal imager 1 is typically used to thermally image the overall direction and leakage situation of the underground pipeline. Existing thermal imagers 1 mainly consist of three modules: a support frame, a data acquisition probe, and an imaging display screen. To facilitate portability, some thermal imagers 1 have a multi-directionally rotatable adjustable storage structure between the support frame and the imaging display screen. This method reduces the size of the thermal imager 1 for easy portability. Some models have a dedicated storage box for the display screen that folds up for storage, while most only fold up. The former cannot guarantee against dust accumulation inside the storage box during long-term operation, leading to a risk of short circuits due to dust contact with the display screen after storage. The latter... Directly exposing the space for transport significantly increases the risk of short circuits due to dust exposure. Instead of using traditional storage boxes and direct exposure, a snap-fit ​​slider 21 is installed on both sides of the original thermal imager 1 to install a dust cover 22 for normal display screen dust protection. Before installing the dust cover 22, the support plate 33 on the outside of the dust cover 22 is removed first. The contaminated wiping cotton 25 supported on the inside of the support plate 33 is replaced by plugging or sticking it in. Then, the elastic pressure plate 36 located on the outside of the support plate 33 is tightened, causing the telescopic column 35 between the elastic pressure plate 36 and the support block 34 and its outer tension spring 37 to stretch and accumulate elastic potential energy. While maintaining this state, the support plate 33 carrying the wiping cotton 25 is inserted into the dust cover. The cleaning cotton 25 is inserted into the mounting slot 32 on the outside of the dust cover 22, ensuring that it fits snugly into the mounting groove 31 on the outside of the dust cover 22. Then, the pressure on the elastic pressure plate 36 is released, allowing the elastic pressure plate 36 to pull back under the rebound of the telescopic column 35 and its outer tension spring 37, pressing down the limiting support plate 33. This completes the installation, and the dust cover 22 can be disassembled by reversing the operation. After the dust cover 22 and the cleaning cotton 25 are integrated, the inner groove of the dust cover 22 is aligned with the snap-fit ​​slider 21 on the outside of the display screen, and then pushed inward for sliding installation. On the smoother side of the snap-fit ​​slider 21, multiple travel grooves 23a are provided, and within each travel groove 23a, an arc-shaped extrusion block 23d supported by the telescopic extrusion column 23b of the external pressure spring 23c is provided. The dust cover 22 has an elastic structure, and an arc-shaped extrusion strip 24 is fixedly connected to the inner wall of the dust cover 22 on the opposite side of the arc-shaped extrusion block 23d. The arc-shaped extrusion strip 24 is a long strip structure composed of multiple protrusions. When the dust cover 22 slides inward along the locking slider 21, the arc-shaped extrusion strip 24 squeezes the arc-shaped extrusion block 23d into the stroke groove 23a and presses the telescopic extrusion column 23b and the compression spring 23c on its outer side between the arc-shaped extrusion block 23d and the stroke groove 23a. After the dust cover 22 slides to the end point through the locking slider 21 and completes the sliding connection, the side of the dust cover 22 with the arc-shaped extrusion strip 24 is elastically locked by the stroke counter-thrust of the arc-shaped extrusion block 23d inside the multiple stroke grooves 23a evenly distributed inside the locking slider 21.Furthermore, the dust cover 22 and the snap-fit ​​slider 21 are mutually positioned by a second positioning magnet 5 and adhere to each other. In summary, stable installation is achieved through sliding, elastic snap-fit, and magnetic attraction, allowing only reverse pulling for unidirectional disassembly. This replaces the traditional storage box to protect the display screen from external dust. During use, when the dust cover 22 is pulled out unidirectionally, the cleaning cotton 25 quickly slides across the display surface and wipes it for auxiliary cleaning. This cotton can be reused until most of the surface is soiled before replacement. In summary, this optimizes the usage process of the thermal imager 1.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
