Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline inspection technology, and in particular to a thermal pipeline leak location and detection device. Background Technology

[0002] As a crucial component of industrial heating systems, thermal pipelines play a vital role in transmitting high-temperature, high-pressure fluids. Due to aging of pipeline materials, defects during construction and installation, and wear and tear during long-term operation, leaks are inevitable in thermal pipelines. Therefore, regular inspection and maintenance of thermal pipelines, and timely detection and repair of leaks, are key to ensuring the safe and stable operation of the heating system. When leaks occur in underground thermal pipelines, acoustic leak detectors are typically used to locate them. This technology utilizes sound detection to pinpoint the leak, enabling workers to quickly and accurately locate the leak, repair the pipeline promptly, and avoid wasting resources and polluting the environment.

[0003] However, current sound leak detectors typically require one hand to hold the main unit and the other to hold the sound sensor and place it on the ground to detect pipe leaks. Because the detection position needs to be changed frequently during the detection process, the staff has to lift the sound sensor, move it, and then re-place it on the ground. The operation is cumbersome, time-consuming, and labor-intensive, causing a lot of trouble for the location and detection of leaks in thermal pipelines.

[0004] Therefore, it is necessary to develop a leak detection device for thermal pipelines to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a leak location and detection device for thermal pipelines, which effectively overcomes the defects of the prior art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A leak detection device for thermal pipelines includes a movable support, a leak detector, and a drive mechanism. The leak detector is connected to a sound sensor probe via a circuit. The drive mechanism is mounted on the movable support and connected to the sound sensor probe, and is used to drive the sound sensor probe to move downwards to the ground or upwards to be suspended in the air.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the aforementioned drive mechanism includes a vertically extending column, the lower end of which passes through the aforementioned movable support. The aforementioned sound sensing probe is mounted on the lower end of the column, and a handle is provided at the upper end of the column. A spring-loaded component is connected between the aforementioned movable support and the lower end of the aforementioned column. The handle is used to drive the aforementioned column downward under the action of external force, and the spring-loaded component is used to drive the aforementioned column upward back to its original position after the external force is removed.

[0010] Furthermore, the lower end of the aforementioned column is provided with a plurality of vertically extending grooves at intervals along the circumference, and the inner wall of the aforementioned fixed sleeve is provided with guide blocks that are embedded in the aforementioned grooves one by one.

[0011] Furthermore, the aforementioned movable support includes multiple bent support legs, which are distributed circumferentially. The upper ends of the multiple support legs are connected to a fixed sleeve. The lower ends of the support legs are equipped with casters. The lower end of the column passes through the fixed sleeve. The aforementioned rebound component is mounted on the support legs.

[0012] Furthermore, the aforementioned rebound component includes multiple sliders and multiple guide rods. The multiple guide rods are fixed one-to-one to the upper ends of the multiple support feet and distributed around the perimeter of the column. The multiple sliders are fixed at intervals along the circumference to the lower end of the column. Each slider has a through hole adapted to the guide rod and is fitted onto the multiple guide rods one-to-one. A first elastic element is installed between the slider and the upper end of the corresponding support foot.

[0013] Furthermore, it also includes a locking assembly, which comprises a pull rod, a rocker arm, and an L-shaped locking hook. The lower end of the grip is provided with a first hinge seat, and the lower end of the column is provided with a second hinge seat near one of the sliders. One end of the rocker arm is hinged to the first hinge seat, and the upper end of the pull rod is hinged to the other end of the rocker arm. A second elastic element connects the rocker arm and the upper end of the column. The upper end of the locking hook is connected to a laterally extending linkage rod, one end of which is hinged to the second hinge seat, and the lower end of the pull rod is hinged to the upper... The other end of the linkage rod is hinged. One of the sliders has a channel communicating with the through hole at the end away from the column. The upper surface of the guide rod passing through the slider has a hook groove that engages with the hook of the locking hook. The rocker arm has a handle on the side away from the column. The handle is used to drive the rocker arm to swing upward under the action of external force, and to pull the linkage rod to swing through the pull rod, so that the locking hook disengages from the hook groove on the upper part of the guide rod and the channel at one end of the slider, and stretches the second elastic member, so that the column can move downward.

[0014] Furthermore, the leak detector is mounted on a bracket, which is detachably mounted on the upper end of the column.

[0015] Furthermore, the sound sensor probe is provided with a soundproof cover with an open lower end. The sound sensor probe is mounted on the inner top of the soundproof cover. A sealing ring protruding from the lower part of the outer periphery of the soundproof cover is provided. A sound insulation layer is provided on the inner side of the soundproof cover. The top of the soundproof cover is connected and assembled with the drive mechanism.

[0016] Furthermore, the upper end of the aforementioned sound sensing probe is provided with a threaded post, and the inner side of the top of the aforementioned soundproof cover is provided with an internal threaded sleeve, and the aforementioned threaded post and the aforementioned internal threaded sleeve are threadedly connected.

[0017] Furthermore, the aforementioned soundproof cover is horn-shaped.

[0018] The advantages of this invention are: the structure is reasonably designed, the whole device can be moved flexibly, and during testing, it is only necessary to operate the drive component to make the sound sensing probe land, which is relatively convenient to operate.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example: Figure 1 , 2 As shown, the thermal pipeline leak location and detection device of this embodiment includes a movable support 1, a leak detector 2, and a drive mechanism 3. The leak detector 2 is connected to a sound sensor probe 21 via a line. The drive mechanism 3 is mounted on the movable support 1 and connected to the sound sensor probe 21, and is used to drive the sound sensor probe 21 to move downward to the ground or move upward to be suspended in the air.

[0028] In this embodiment, the thermal pipeline leak location and detection device is used by moving the device to a suitable detection position via the movable support 1. Then, the drive mechanism 3 drives the sound sensor probe 21 to the ground, allowing it to detect leaks in underground thermal pipelines. When fluid leaks in a thermal pipeline, turbulence or eddies are generated at the leak point, producing specific sound signals. The sound sensor probe 21 captures these signals and sends them to the leak detector 2 for analysis of signal intensity, frequency, and other characteristics, facilitating the determination of the leak location. After detection, the drive mechanism 3 returns the sound sensor probe 21 to its suspended position. The movable support 1 allows operators to easily move the device to any location for further detection. Compared to traditional detection methods, this significantly reduces labor intensity, saves time and effort, and greatly facilitates the location and detection of leaks in thermal pipelines.

[0029] In this embodiment, the leak detector 2 is an existing instrument, and the model can be adapted according to actual needs, which will not be described in detail here.

[0030] As a preferred implementation method, such as Figure 1 , 2 As shown, the drive mechanism 3 includes a vertically extending column 31, the lower end of which passes through the movable support 1. The sound sensor probe 21 is mounted on the lower end of the column 31. A handle 32 is provided at the upper end of the column 31. A spring-loaded component 4 is connected between the movable support 1 and the lower end of the column 31. The handle 32 is used to drive the column 31 downward under the action of external force, and the spring-loaded component 4 is used to drive the column 31 upward back to its original position after the external force is removed.

[0031] In the above implementation scheme, during use, applying pressure to the column 31 by holding the handle 32 with one hand allows the column 31 to move downwards relative to the movable support 1, enabling the sound sensor probe 21 to be placed against the ground for detecting leaks in underground thermal pipelines. Operation is convenient and labor-saving. After detection, releasing the handle 32 allows the rebound component 4 to move the column 31 back to its original position, leaving the sound sensor probe 21 suspended for future use.

[0032] As a preferred implementation method, such as Figure 3 As shown, the movable support 1 includes a plurality of bent support legs 11, which are distributed circumferentially. The upper ends of the plurality of support legs 11 are connected to a fixed sleeve 12. The lower ends of the support legs 11 are equipped with casters 13. The lower end of the column 31 passes through the fixed sleeve 12. The support legs 11 are equipped with the spring-loaded component 4.

[0033] In the above implementation scheme, the design of the fixing sleeve 12 can restrict the vertical movement of the column 31. Note that the dimensions of the fixing sleeve 12 are the same as those of the column 31, which allows the column 31 to maintain vertical movement to a certain extent. The entire movable support 1 structure is relatively simple in design, provides stable support on the ground, and allows for flexible movement.

[0034] In this embodiment, caster 13 is a universal wheel of the appropriate model.

[0035] In this embodiment, the lower end of the column 31 is provided with a plurality of vertically extending grooves (a in the figure) spaced apart along the circumference. The inner wall of the fixed sleeve 12 is provided with guide blocks that are correspondingly embedded in the grooves. The sliding engagement between the guide blocks and the grooves prevents the column 31 from rotating when it moves downward, thereby ensuring that the column 31 maintains a good vertical state during movement, avoiding tilting and shaking, and allowing the sound sensor probe 21 to effectively contact the ground for monitoring.

[0036] In a preferred embodiment, the rebound component 4 includes multiple sliders 41 and multiple guide rods 42. The guide rods 42 are fixed one-to-one to the upper ends of the multiple support feet 11 and distributed around the perimeter of the column 31. The sliders 41 are fixed at intervals along the circumference to the lower end of the column 31. Each slider 41 has a through hole adapted to the guide rod 42 and is fitted onto the guide rod 42. A first elastic element 43 is installed between the slider 41 and the upper end of the corresponding support foot 11. The lower outer periphery of the column 31 has multiple vertically extending grooves spaced at intervals along its circumference. The ends of the sliders 41 are respectively embedded in the grooves and can move up and down relative to the grooves.

[0037] The ends of the multiple sliders 41 that are close to each other are respectively attached to the surface of the column 31, and the ends of the sliders 41 that are close to each other are respectively provided with fitting protrusions embedded in the grooves.

[0038] In the above implementation scheme, during the process of the column 31 moving downward under pressure, the slider 41 compresses the first elastic member 43 downward. After the monitoring is completed and the external force is removed, the first elastic member 43 rebounds, causing the slider 41 to drive the column 31 to move upward back to its original position. The design is quite ingenious.

[0039] In this embodiment, the first elastic element 43 is a spring sleeved on the outside of the guide rod 42.

[0040] As a preferred implementation method, such as Figure 4 As shown, it also includes a locking assembly 5, which includes a pull rod 51, a rocker arm 52, and an L-shaped locking hook 53. The lower end of the grip 32 is provided with a first hinge seat 321, and the lower end of the column 31 is provided with a second hinge seat 311 near one of the sliders 41. One end of the rocker arm 52 is hinged to the first hinge seat 321, and the upper end of the pull rod 51 is hinged to the other end of the rocker arm 52. A second elastic member 54 is connected between the rocker arm 52 and the upper end of the column 31. The upper end of the locking hook 53 is connected to a laterally extending linkage rod 531. One end of the linkage rod 531 is hinged to the second hinge seat 311, and the lower end of the pull rod 51 is hinged to the linkage rod. The other end of 531 is hinged. One of the sliders 41 is provided with a channel (b in the figure) that communicates with the through hole at the end away from the column 31. The upper surface of the guide rod 42 that passes through the slider 41 is provided with a hook groove (c in the figure) that engages with the hook of the locking hook 53. The rocker arm 52 is provided with a handle 521 on the side away from the column 31. The handle 521 is used to drive the rocker arm 52 to swing upward under the action of external force, and pull the linkage rod 531 to swing through the pull rod 51, so that the locking hook 53 disengages from the hook groove on the upper part of the guide rod 42 and the channel at one end of the slider 41, and stretches the second elastic member 54, so that the column 31 can move downward.

[0041] In the above implementation scheme, when the column 31 is not pressed and the sound sensor probe 21 is suspended, the second elastic member 54 will always apply a pulling and retracting force to the rocker arm 52, the pull rod 51 is in a low position, and at this time, the hook groove is in the position facing the port of the channel, the lower end of the locking hook 53 passes through the port of the channel and is embedded in the hook groove, maintaining this state. At this time, the column 31 will be locked, and even if a pressing force is applied, the column 31 will not move down. This state keeps the sound sensor probe 21 in a suspended state, and during the movement of the operating device, it can avoid the situation where the column 31 is accidentally pressed down and moves downward, causing the sound sensor probe 21 to come into contact with the ground and cause friction.

[0042] In this embodiment, the second elastic element 54 is a spring of a suitable type.

[0043] In this embodiment, the leak detector 2 is mounted on the bracket 22, and the bracket 22 is detachably mounted on the upper end of the column 31.

[0044] As a preferred implementation method, such as Figure 5 As shown, the sound sensor probe 21 is provided with a soundproof cover 6 with an open lower end. The sound sensor probe 21 is mounted on the inner side of the top of the soundproof cover 6. A sealing ring 61 protruding from the lower part of the outer periphery of the soundproof cover 6 is provided. A sound insulation layer (d in the figure refers to sound insulation cotton) is provided on the inner side of the soundproof cover 6. The top of the soundproof cover 6 is connected and assembled with the drive mechanism 3.

[0045] In the above implementation scheme, during detection, the lower end of the soundproof enclosure 6 contacts the ground, creating a relatively sealed and quiet environment. This eliminates the need for the sound sensor probe 21 to contact the ground and minimizes interference from external sounds, resulting in more accurate monitoring results. Simultaneously, the sealing ring 61 is designed to directly contact the ground when the soundproof enclosure 6 is placed on the ground. Under pressure, the sealing ring 61 fits tightly against the ground without gaps, further eliminating noise.

[0046] In this embodiment, the locking component 5 keeps the column 31 in a high position, and can also prevent the sealing ring 61 from being worn due to contact with the ground during the movement of the device.

[0047] In this embodiment, the upper end of the sound sensor probe 21 is provided with a threaded post, and the inner side of the top of the soundproof cover 6 is provided with an internal threaded sleeve (e in the figure), and the threaded post and the internal threaded sleeve are threadedly connected. This design facilitates the assembly and disassembly of the sound sensor probe 21.

[0048] In this embodiment, the soundproof cover 6 is horn-shaped.
