Description

Technical Field

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

[0002] Heating pipelines, including those connecting the heat source to the heating station and those connecting the heating station to the user, are densely packed like capillaries in the human body, forming a complex network. During use, heating pipelines are subjected to wear, high temperatures, corrosion, and other factors. Combined with disturbances during operation, hot water pipelines gradually develop cracks, deformations, and leaks. If no measures are taken, these defects can escalate into accidents such as breakage, leakage, and bursting. Therefore, regular or irregular inspections of heating pipelines are necessary.

[0003] A search revealed a heating pipe network leak location and detection device with application number 202223390495.2, comprising a heating pipe network and a power supply unit; a support frame is provided at the upper outer side of the heating pipe network, and a balance box is provided at the lower left and right sides of the support frame; a moving unit is provided between the upper left and right sides of the support frame inside the support frame along the left-right direction; the support frame is slidably connected to the upper outer side of the heating pipe network through the outer side of the moving unit; a detection unit is provided at the rear side of the support frame; the power supply unit includes a square groove, a solar panel, and a battery.

[0004] However, the aforementioned heating pipeline leak detection device has some shortcomings in its use. The device is relatively fixed, which means it can only be used to detect heating pipelines of one size, making it inconvenient to detect heating pipelines of different sizes. This greatly reduces the practicality and versatility of the device, resulting in poor performance. Therefore, we propose a heating pipeline leak detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by proposing a leak detection device for heating pipelines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leak detection device for heating pipelines includes a frame mounted on top of the heating pipeline. A shield is fixedly connected to the top of the frame, and two photovoltaic panels are fixedly connected to the top of the shield. A battery connected to the photovoltaic panels and a controller with communication function are fixedly connected to the top of the frame. An installation frame and two gantry frames are installed inside the frame. A drive mechanism is installed on the installation frame, and a guide mechanism is installed on the gantry frames. A synchronous adjustment mechanism is provided between the frame, the installation frame, and the two gantry frames. A temperature sensor and a smoke sensor are fixedly connected to the top of the installation frame, and a weight-adding plate is fixedly connected to the bottom of the frame.

[0008] As a preferred embodiment of the present invention, the driving mechanism includes a driving motor fixedly connected to one side of the mounting frame and driving rollers rotatably connected to the inner walls on both sides of the mounting frame. One end of the driving roller is fixedly connected to the output shaft of the driving motor, and an upper anti-slip rubber sleeve is fixedly sleeved on the outer side of the driving roller.

[0009] In a preferred embodiment of this invention, the drive roller is rotatably connected to the inner walls of both sides of the mounting frame via two bearings.

[0010] As a preferred embodiment of this utility model, the guiding mechanism includes multiple rotating shafts rotatably connected to the upper and lower inner walls of the gantry frame, with guide rollers fixedly sleeved on the outer side of each rotating shaft, and a lower anti-slip rubber sleeve fixedly sleeved on the outer side of each guide roller.

[0011] As a preferred embodiment of this invention, multiple lower anti-slip rubber sleeves are respectively movably abutting against both sides of the heating pipe.

[0012] In a preferred embodiment of this utility model, the synchronous adjustment mechanism includes a hydraulic cylinder fixedly connected to the top of the frame, the output shaft of the hydraulic cylinder fixedly connected to the top of the mounting frame, connecting plates fixedly connected to both sides of the mounting frame, a vertical rack fixedly connected to the bottom of the connecting plates, two support plates fixedly connected to both sides of the frame, and a common rotating shaft rotatably connecting the two support plates on the same side, an intermediate gear and two external gears fixedly sleeved on the outer side of the rotating shaft, the intermediate gear meshing with the vertical rack, and two horizontal racks fixedly connected to the outer side of the gantry frame, the two external gears meshing with their respective horizontal racks.

[0013] As a preferred embodiment of this utility model, rectangular openings are provided on both sides of the frame, and the same guide rod is fixedly connected to the upper and lower inner walls of the rectangular openings. The connecting plate is slidably sleeved inside the rectangular openings and slidably sleeved outside the guide rods.

[0014] As a preferred embodiment of this utility model, two through slots are provided on both sides of the frame, and two horizontal racks are slidably sleeved in the corresponding through slots. Two telescopic rods are fixedly connected between the gantry frame and the frame.

[0015] In this utility model, a heating pipeline leakage detection device is described. The frame is placed on the outside of the heating pipeline. The hydraulic cylinder is activated by the controller. The output shaft of the hydraulic cylinder drives the mounting frame to move downward, which in turn drives the two connecting plates and the two vertical racks to move downward. The two vertical racks drive the two intermediate gears and the rotating shaft to move inward. The two rotating shafts drive the four external gears to move inward. The four external gears drive the four horizontal racks and the two gantry frames to move closer to each other. Conversely, when the hydraulic cylinder drives the mounting frame to move upward, it will drive the two gantry frames to move closer to each other. Because the vertical racks and horizontal racks have the same specifications, and the intermediate gears and external gears have the same specifications, the distance the gantry frames move inward is the same as the height of the mounting frame moving downward. Since the heating pipeline is circular, it can be effectively used for circular heating pipelines, and the drive roller and guide roller can abut against the outer surface of the heating pipeline.

[0016] In this utility model, a heating pipeline leakage detection device is provided. By setting up a weight plate, the center of gravity of the frame is lowered, ensuring the stability of the frame when placed on the heating pipeline. The drive motor drives the rotation of the drive roller, and under the guidance of the guide roller, the frame can move on the heating pipeline. During the movement, the temperature sensor and the smoke sensor can detect leaks in the heating pipeline. The information detected by the temperature sensor and the smoke sensor can be transmitted to the background through the communication function on the controller.

[0017] This utility model has a reasonable structural design. Through the synchronous adjustment mechanism, the distance between the gantry and the mounting frame can be adjusted simply by starting the hydraulic cylinder. This allows for the detection of leaks in heating pipes of different sizes, greatly improving the practicality and versatility of the device, and ensuring high reliability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A heating pipeline leak detection device includes a frame 1 installed on top of a heating pipeline 2. A shielding plate 7 is fixedly connected to the top of the frame 1. Two photovoltaic panels 8 are fixedly connected to the top of the shielding plate 7. A battery 11 connected to the photovoltaic panels 8 and a controller 9 with communication function are fixedly connected to the top of the frame 1. An mounting frame 6 and two gantry frames 5 are installed inside the frame 1. A drive mechanism is installed on the mounting frame 6 and a guide mechanism is installed on the gantry frames 5. A synchronous adjustment mechanism 4 is installed between the frame 1, the mounting frame 6 and the two gantry frames 5. A temperature sensor 12 and a smoke sensor 13 are fixedly connected to the top of the mounting frame 6. A weight-adding plate 3 is fixedly connected to the bottom of the frame 1.

[0025] Furthermore, refer to Figures 1-3 The driving mechanism includes a drive motor 10 fixedly connected to one side of the mounting frame 6, and drive rollers 17 rotatably connected to the inner walls on both sides of the mounting frame 6. One end of the drive roller 17 is fixedly connected to the output shaft of the drive motor 10. An upper anti-slip rubber sleeve 16 is fixedly sleeved on the outer side of the drive roller 17. The drive roller 17 is rotatably connected to the inner walls on both sides of the mounting frame 6 through two bearings. The guiding mechanism includes multiple rotating shafts rotatably connected to the upper and lower inner walls of the gantry frame 5. A guide roller 14 is fixedly sleeved on the outer side of the rotating shaft. A lower anti-slip rubber sleeve 15 is fixedly sleeved on the outer side of the guide roller 14. The multiple lower anti-slip rubber sleeves 15 are respectively movably abutting against both sides of the heating pipe 2.

[0026] The above scheme is adopted: by setting the weight plate 3, the center of gravity of the frame 1 is lowered, ensuring the stability of the frame 1 placed on the heating pipe 2. The drive motor 10 drives the drive roller 17 to rotate. Under the guidance of the guide roller 14, the frame 1 can move on the heating pipe 2. During the movement, the temperature sensor 12 and the smoke sensor 13 can detect leaks in the heating pipe 2. The information detected by the temperature sensor 12 and the smoke sensor 13 can be transmitted to the background through the communication function on the controller 9.

[0027] Furthermore, refer to Figures 1-4 The synchronous adjustment mechanism 4 includes a hydraulic cylinder 401 fixedly connected to the top of the frame 1. The output shaft of the hydraulic cylinder 401 is fixedly connected to the top of the mounting frame 6. Connecting plates 404 are fixedly connected to both sides of the mounting frame 6. A vertical rack 405 is fixedly connected to the bottom of the connecting plate 404. Two support plates 408 are fixedly connected to both sides of the frame 1. The same rotating shaft 407 is rotatably connected between the two support plates 408 on the same side. An intermediate gear 411 and two external gears 406 are fixedly sleeved on the outer side of the rotating shaft 407. The intermediate gear 411 meshes with the vertical rack 405. Two horizontal racks 409 are fixedly connected to the outer side of the gantry frame 5. The two external gears 406 mesh with the corresponding horizontal racks 409 respectively.

[0028] Using the above scheme: The frame 1 is placed outside the heating pipe 2. The hydraulic cylinder 401 is activated via the controller 9. The output shaft of the hydraulic cylinder 401 drives the mounting bracket 6 downwards, causing the two connecting plates 404 and the two vertical racks 405 to move downwards. The two vertical racks 405 drive the two intermediate gears 411 and the rotating shaft 407 to move inwards. The two rotating shafts 407 drive the four external gears 406 to move inwards. The four external gears 406 drive the four horizontal racks 409 and the two gantry frames 5. When the hydraulic cylinder 401 moves the mounting bracket 6 upward, it will cause the two gantry frames 5 to move closer to each other. Since the vertical rack 405 and the horizontal rack 409 have the same specifications, and the intermediate gear 411 and the external gear 406 have the same specifications, the distance that the gantry frame 5 moves inward is the same as the height that the mounting bracket 6 moves downward. Since the heating pipe 2 is circular, the circular heating pipe 2 can be used effectively, so that the drive roller 17 and the guide roller 14 can abut against the outer surface of the heating pipe 2.

[0029] Furthermore, rectangular openings 402 are provided on both sides of the frame 1. The same guide rod 403 is fixedly connected to the upper and lower inner walls of the rectangular openings 402. The connecting plate 404 is slidably sleeved in the rectangular openings 402 and slidably sleeved on the outside of the guide rod 403, which facilitates the guidance of the connecting plate 404 and the mounting frame 6, making their lifting root more stable.

[0030] Furthermore, two through slots 410 are provided on both sides of the frame 1, and two horizontal racks 409 are slidably sleeved in the corresponding through slots 410. Two telescopic rods 412 are fixedly connected between the gantry frame 5 and the frame 1, which can guide the gantry frame 5 and the horizontal racks 409 to make their movement more stable.

[0031] In this invention, during use, the frame 1 is placed outside the heating pipe 2. The controller 9 activates the hydraulic cylinder 401. The output shaft of the hydraulic cylinder 401 drives the mounting frame 6 downwards, causing the two connecting plates 404 and two vertical racks 405 to move downwards. The two vertical racks 405 drive the two intermediate gears 411 and the rotating shaft 407 to move inwards. The two rotating shafts 407 drive the four external gears 406 to move inwards. The four external gears 406 drive the four horizontal racks 409 to move closer to each other. Conversely, when the hydraulic cylinder 401 drives the mounting frame 6 upwards, it will cause the two gantry frames 5 to move closer to each other. Because the vertical racks 405 and horizontal racks 409 have the same specifications, and the intermediate gears 411 and external gears 406 have the same specifications, the distance the gantry frames 5 move inwards is related to the distance the mounting frame 6 moves. The downward movement is the same. Since the heating pipe 2 is circular, the circular heating pipe 2 can be effectively used, allowing the drive roller 17 and guide roller 14 to abut against the outer surface of the heating pipe 2. The weight plate 3 lowers the center of gravity of the frame 1, ensuring the stability of the frame 1 on the heating pipe 2. The drive motor 10 drives the drive roller 17 to rotate. Under the guidance of the guide roller 14, the frame 1 can move on the heating pipe 2. During the movement, the temperature sensor 12 and the smoke sensor 13 can detect leaks in the heating pipe 2. The specific detection principle is the same as that in a heating pipe network leak location detection device with patent number CN219571658U. The information detected by the temperature sensor 12 and the smoke sensor 13 can be transmitted to the background through the communication function on the controller 9.
