Description

Technical Field

[0001] This utility model relates to the field of heating pipeline inspection technology, specifically a vehicle-mounted heating pipeline inspection device based on infrared imaging. Background Technology

[0002] Urban heating pipelines are one of the important urban infrastructures. With the rapid development of centralized heating in cities, the scale and diameter of heating pipelines are also increasing. As of the end of 2020, the length of centralized heating pipelines in my country reached 426,000 kilometers. As the operating years of heating pipelines increase year by year, the early-built heating pipelines are aging. In addition, pipeline corrosion, sudden changes in water hammer pressure, and the impact of natural disasters such as earthquakes have led to a year-on-year increase in heating pipeline leakage accidents, resulting in the loss and waste of energy and water resources, and even ground subsidence, seriously affecting urban heating and the safety of people's lives and property.

[0003] For example, the authorized announcement number "CN220120297U" is titled "Intelligent Imaging Heating Pipeline Inspection Device." Inspectors use a handle and wheels to move the riser along the pre-buried route of the heating pipeline. During this movement, a binocular thermal imaging camera on the riser takes real-time thermal images of the pipeline and wirelessly transmits the images to the inspector's mobile smart terminal for display. However, existing technology has certain problems. For instance, traditional manual inspection requires staff to carry a handheld thermal imager on foot, with a single inspection coverage radius of less than 500 meters. In winter, the average daily inspection distance is less than 5 kilometers. Furthermore, the screen size of handheld devices is generally less than 5 inches, making it difficult to detect subtle temperature changes in bumpy environments. Additionally, battery life decreases by up to 40% in cold weather, requiring operators to frequently replace the battery, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing intelligent imaging heating pipeline inspection devices, such as limited single-detection coverage radius of less than 500 meters, low detection range, difficulty in identifying subtle temperature changes due to the generally smaller screen size of handheld devices (less than 5 inches), and short battery life in cold outdoor weather, which burdens operators. Therefore, this invention proposes a vehicle-mounted infrared imaging-based heating pipeline inspection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a vehicle-mounted infrared imaging-based heating pipeline inspection device, including a vehicle-mounted base, an infrared thermoforming module, and an electric controller. The electric controller is fixedly installed on one side of the top of the vehicle-mounted base. The vehicle-mounted base has a vehicle-mounted infrared imaging rotating snap-fit ​​structure on its upper part. The lower end of the infrared thermoforming module has an adjustable handheld structure for the thermal imaging device. The vehicle-mounted base has a spare vehicle-mounted power connection structure on its outer side.

[0007] This feature involves placing the vehicle-mounted base at the front of the driver's cab for easy access by staff. The electric controller can be connected to a remote control device via a circuit, allowing staff to control the motor's start-up using the remote control components.

[0008] Preferably, the vehicle-mounted infrared imaging rotating snap-fit ​​structure includes a support platform and an adhesive layer. The adhesive layer is fixedly connected to the lower end of the vehicle base, the support platform is fixedly installed on the top of the vehicle base, a motor is fixedly installed on the inner side of the support platform, a first gear is fixedly installed on the top of the output shaft of the motor, a second gear is meshed with the side wall of the first gear, a magnetic suction plate is fixedly connected to the top of the second gear, and the second gear is rotatably connected to the inner side of the support platform.

[0009] This setup utilizes a highly adhesive layer, allowing it to adhere firmly to the front of the vehicle's cab. This secures the support platform within the vehicle's interior, facilitating thermal imaging inspections. The infrared thermoforming module can be vertically inserted into the support platform via a lower magnetic shaft. Since both the magnetic shaft and magnetic plate are made of opposite magnetic materials, they are secured through magnetic attraction. When the motor starts, its output shaft drives the first gear to rotate. This first gear, in turn, drives the second gear, which in turn rotates. The second gear, using the top magnetic plate, adjusts the lateral rotation angle of the infrared thermoforming module's front end.

[0010] Preferably, the adjustable handheld structure of the thermal imaging device includes a pole and positioning shafts. The positioning shafts are rotatably connected to both sides of the outer wall of the infrared thermoforming module. The outer sides of the two positioning shafts are rotatably connected to brackets. The lower ends of the two brackets are fixedly connected to the pole. The lower end of the outer wall of the infrared thermoforming module is movably connected to a small electric telescopic rod. A handheld grip is provided on the rear side of the infrared thermoforming module.

[0011] This positioning axis allows the central infrared thermoforming module to rotate back and forth at a certain angle inside the bracket. The rotation angle of the infrared thermoforming module is controlled by the small electric telescopic rod below. Under normal circumstances, the infrared thermoforming module tilts and falls to the front due to its weight. By connecting the power supply and using the small electric telescopic rod, the front of the infrared thermoforming module can be pushed upward to rotate it. The vertical angle can be adjusted within the pitch angle ±25°, so the small electric telescopic rod is sufficient to meet the adjustment requirements within a reasonable range.

[0012] Preferably, an infrared imaging module rotation limiting structure is provided above the support platform. The infrared imaging module rotation limiting structure includes a sleeve and a connecting plate. The sleeve is fixedly installed on the top of the support platform. A roller is rotatably connected to the inner side of the sleeve. A magnetic suction shaft is slidably connected to the outer wall of the roller. A connecting block is fixedly connected to the top of the magnetic suction shaft. A threaded rod is threadedly connected to the top of the connecting block. The connecting plate is fixedly connected to the top of the threaded rod. The top of the connecting plate is fixedly connected to the lower end of the hand grip.

[0013] This feature allows the inner side of the sleeve to use rollers to restrict the rotation of the magnetic shaft, reducing friction on the outer side of the magnetic shaft. The connecting block can be connected to the upper connecting plate via a threaded rod. In other words, the hand grip can directly pull the magnetic shaft upwards and then use the top infrared thermoforming module for hand operation. Alternatively, the connecting plate can be twisted in the opposite direction, and the threaded rod can be used to reverse the connection plate to disassemble it, allowing for hand operation of the lighter infrared thermoforming module.

[0014] Preferably, the backup vehicle power connection structure includes a vehicle battery and a power cord. The other end of the power cord is fixedly connected to the outside of the infrared thermoforming module. A connector is fixedly installed on the other end of the power cord, and the other end of the connector is movably plugged into the vehicle battery.

[0015] This setting allows the power cord to be connected to the infrared thermoforming module, which can then be plugged into the vehicle battery via a connector and powered by the vehicle battery. Therefore, the main body of the device adopts a vehicle power supply system, supporting continuous operation in an environment of 20°C.

[0016] Preferably, an industrial-grade large display screen is electrically connected to the outside of the infrared thermoforming module, a mounting block is fixedly connected to the outer wall of the industrial-grade large display screen, and a control box is fixedly connected to the lower end of the industrial-grade large display screen.

[0017] This industrial-grade large display screen is equipped with an infrared thermoforming module and can detect subtle temperature changes in bumpy environments. The mounting block uses multiple aluminum alloy metal rings, so it can be hung inside the vehicle for convenient use while driving. The control box is the integrated control chip of the display screen, which can transfer the thermal imaging images captured and identified by the infrared thermoforming module to the industrial-grade large display screen for display.

[0018] This utility model proposes a vehicle-mounted infrared imaging-based heating pipeline inspection device, which has the following advantages: the vehicle-mounted mobile detection speed can reach 30km / h, the daily inspection mileage exceeds 100km, it is equipped with a 13-inch industrial-grade large display screen, and it can identify subtle temperature changes in bumpy environments; the power cord can be connected to the infrared thermoforming module, so the infrared thermoforming module can be inserted into the vehicle battery through the connector and powered by the vehicle battery. Therefore, the main body of the device adopts a vehicle-mounted power supply system, which supports continuous operation in an environment of -20℃, and does not require frequent battery replacement by the staff.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] Please see Figure 1-7 In this embodiment, a vehicle-mounted infrared imaging-based heating pipeline inspection device includes a vehicle-mounted base 1, an infrared thermoforming module 2, and an electric controller 3. The electric controller 3 is fixedly installed on one side of the top of the vehicle-mounted base 1. The vehicle-mounted base 1 is placed at the front of the driver's cab of the vehicle for easy use by the staff. The electric controller 3 can be connected to a remote control device via a circuit. The staff can use the remote control component to control the start-up of the motor 42. The vehicle-mounted base 1 is provided with a vehicle-mounted infrared imaging rotating snap-fit ​​structure 4 on the top. The infrared thermoforming module 2 is provided with an adjustable handheld structure 6 for the thermal imaging device at the bottom. The vehicle-mounted base 1 is provided with a spare vehicle-mounted power connection structure 7 on the outside.

[0029] The vehicle-mounted infrared imaging rotating snap-fit ​​structure 4 includes a support platform 41 and an adhesive layer 46. The adhesive layer 46 is fixedly connected to the lower end of the vehicle-mounted base 1. The adhesive layer 46 uses a relatively sticky adhesive layer, so that the adhesive layer 46 can be firmly attached to the front end of the vehicle cab, which can fix the support platform 41 to the front end of the vehicle interior, facilitating thermal imaging inspection. The support platform 41 is fixedly installed on the top of the vehicle-mounted base 1. A motor 42 is fixedly installed on the inner side of the support platform 41. The motor 42 is a servo motor. A first gear 43 is fixedly installed on the top of the output shaft of the motor 42. A second gear 44 is meshed with the side wall of the first gear 43. A magnetic suction plate 45 is fixedly connected to the top of the second gear 44. The infrared thermoforming module 2 can be vertically inserted into the support platform 41 through the lower magnetic suction shaft 52 for fixation. In this way, the magnetic suction shaft 52 and the magnetic suction plate 45 are both magnetic materials with opposite magnetic poles, and the two can be fixed by magnetic attraction. When the motor 42 is started, the output shaft of the motor 42 can drive the first gear 43 to rotate. The first gear 43 can drive the second gear 44 meshed on one side to rotate. The second gear 44 uses the top magnetic suction plate 45 to drive the front end of the infrared thermoforming module 2 to adjust the horizontal rotation angle. The second gear 44 is rotatably connected to the inside of the support platform 41.

[0030] The adjustable handheld structure 6 of the thermal imaging device includes a pole 61 and a positioning shaft 64. The positioning shaft 64 is rotatably connected to both sides of the outer wall of the infrared thermoforming module 2. The positioning shaft 66 allows the infrared thermoforming module 2 in the middle to rotate back and forth at a certain angle on the inner side. In this way, the infrared thermoforming module 2 can rotate inside the bracket 63. The rotation angle of the infrared thermoforming module 2 is controlled by the small electric telescopic rod 62 below. Under normal circumstances, the infrared thermoforming module 2 tilts and falls to the front end due to its weight. When connected to the power supply, the small electric telescopic rod 62 can be used to push the front end of the infrared thermoforming module 2 upward and rotate it. The vertical angle can be adjusted. The vertical angle adjustment range is within ±25° of the pitch angle. Therefore, the small electric telescopic rod 62 is sufficient to meet the adjustment requirements within a reasonable range. The outer sides of the two positioning shafts 64 are rotatably connected to the bracket 63. The lower ends of the two brackets 63 are fixedly connected to the pole 61. The lower end of the outer wall of the infrared thermoforming module 2 is movably connected to the small electric telescopic rod 62. A hand grip 65 is provided on the rear side of the infrared thermoforming module 2.

[0031] An infrared imaging module rotation limiting structure 5 is provided above the support platform 41. The infrared imaging module rotation limiting structure 5 includes a sleeve 51 and a connecting plate 56. The inner side of the sleeve 51 can be restricted to rotate the magnetic suction shaft 52 by using a roller 53 to reduce the friction on the outer side of the magnetic suction shaft 52. The sleeve 51 is fixedly installed on the top of the support platform 41. The inner side of the sleeve 51 is rotatably connected to the roller 53. The outer wall of the roller 53 is slidably connected to the magnetic suction shaft 52. The top of the magnetic suction shaft 52 is fixedly connected to a connecting block 54. The connecting block 54 is connected to a threaded rod 55. It can be connected to the upper connecting plate 56, which means that the hand grip 65 can directly pull the magnetic shaft 52 upward and then hold the infrared thermoforming module 2 at the top for hand operation. Alternatively, the connecting plate 56 can be twisted in the opposite direction, and the connecting plate 56 can be disassembled by reversing the threaded rod 55. The lighter infrared thermoforming module 2 can then be held for hand operation. The upper part of the connecting block 54 is threaded with a threaded rod 55, and the connecting plate 56 is fixedly connected to the top of the threaded rod 55. The top of the connecting plate 56 is fixedly connected to the lower end of the hand grip 65.

[0032] The backup vehicle-mounted power supply structure 7 includes a vehicle-mounted battery 71 and a power cord 73. The other end of the power cord 73 is fixedly connected to the outside of the infrared thermoforming module 2. The power cord 73 can be connected to the infrared thermoforming module 2. In this way, the infrared thermoforming module 2 can be inserted into the vehicle-mounted battery 71 through the connector 72 and powered by the vehicle-mounted battery 71. Therefore, the main body of the device adopts a vehicle-mounted power supply system, which supports continuous operation in an environment of -20℃. The other end of the power cord 73 is fixedly installed with a connector 72, and the other end of the connector 72 is movably inserted into the vehicle-mounted battery 71.

[0033] An industrial-grade large display screen 82 is electrically connected to the outside of the infrared thermoforming module 2. The industrial-grade large display screen 82 is a 13-inch industrial-grade large display screen equipped with the infrared thermoforming module 2. It can identify subtle temperature changes in bumpy environments. A mounting block 83 is fixedly connected to the outer wall of the industrial-grade large display screen 82. The mounting block 83 is made of multiple aluminum alloy metal rings, so the mounting block 83 can be hung inside the vehicle for convenient use while driving. A control box 81 is fixedly connected to the lower end of the industrial-grade large display screen 82. The control box 81 is the integrated control chip of the display screen, which can transfer the thermal imaging image captured and identified by the infrared thermoforming module 2 to the industrial-grade large display screen 82 for display.

[0034] Working principle:

[0035] The vehicle-mounted infrared imaging-based heating pipeline inspection device is fixed to a car, which then travels along roads close to the heating pipeline layout, enabling efficient heating pipeline inspections to be performed while the vehicle is in motion.

[0036] The infrared imaging inspection device adopts a pan-tilt system with a magnetic base and an IP67 protection rating. It is equipped with a pitch angle of ±25° and a horizontal rotation of 350° that can be remotely and electrically adjusted.

[0037] The innovative approach of using a vehicle-mounted mobile inspection platform combined with a separate wireless visual system enables human-machine separation inspection, reducing the burden on inspection personnel.

[0038] Vehicle-mounted infrared imaging-based rotating support assembly for inspecting heating pipelines:

[0039] The adhesive layer 46 is made of a relatively sticky adhesive layer, so that the adhesive layer 46 can be firmly attached to the front end of the vehicle cab, and the support platform 41 can be fixed inside the front end of the vehicle for easy thermal imaging inspection. The infrared thermoforming module 2 can be vertically inserted into the support platform 41 for fixation through the lower magnetic suction shaft 52. In this way, the magnetic suction shaft 52 and the magnetic suction plate 45 are both magnetic materials with opposite magnetic poles, and the two can be fixed by magnetic attraction. When the motor 42 is started, the output shaft of the motor 42 can drive the first gear 43 to rotate. The first gear 43 can drive the second gear 44 meshed on one side to rotate. The second gear 44 uses the top magnetic suction plate 45 to drive the front end of the infrared thermoforming module 2 to adjust the lateral rotation angle.

[0040] Vehicle-mounted infrared imaging vertical flip-type component for inspecting heating pipelines:

[0041] The positioning shaft 46 allows the central infrared thermoforming module 2 to rotate back and forth at a certain angle inside, enabling it to rotate within the bracket 63. The rotation angle of the infrared thermoforming module 2 is controlled by the small electric telescopic rod 62 below. Under normal circumstances, the infrared thermoforming module 2 tilts and falls forward due to its weight. Connecting to a power source and using the small electric telescopic rod 62 pushes the front end of the infrared thermoforming module 2 upward, allowing for vertical angle adjustment. The vertical angle adjustment range is within ±25° of the pitch angle, thus the small electric telescopic rod 62 is sufficient to meet adjustment requirements within a reasonable range.

[0042] The inner side of the sleeve 51 can be restricted to rotate by the roller 53, which reduces the friction on the outer side of the magnetic shaft 52. The connecting block 54 can be connected to the upper connecting plate 56 through the threaded rod 55. In other words, the hand grip 65 can directly pull the magnetic shaft 52 upward and then hold the infrared thermoforming module 2 at the top for hand operation. Alternatively, the connecting plate 56 can be twisted in the opposite direction, and the connecting plate 56 can be disassembled by reversing the threaded rod 55. The lighter infrared thermoforming module 2 can then be held for hand operation.

[0043] The infrared thermoforming module 2 uses a dual-spectrum imaging module, which is a relatively mature existing technology. The infrared thermoforming module 2 integrates a 640×512 resolution uncooled infrared detector with a refresh rate of 30Hz and a 4-megapixel starlight-level visible light camera with 20x optical zoom, which can observe and detect the heat inside the heating pipe.

[0044] The industrial-grade large display screen 82 is a 13-inch industrial-grade large display screen equipped with infrared thermoforming module 2, which can identify subtle temperature changes in bumpy environments. The mounting block 83 uses multiple aluminum alloy metal rings, so the mounting block 83 can be hung inside the vehicle for convenient use while driving. The control box 81 is the integrated control chip of the display screen, which can transfer the thermal imaging image captured and identified by the infrared thermoforming module 2 to the industrial-grade large display screen 82 for display.

[0045] The power cord 73 can be connected to the infrared thermoforming module 2, so that the infrared thermoforming module 2 can be inserted into the vehicle battery 71 through the connector 72 and powered by the vehicle battery 71. Therefore, the main body of the device adopts a vehicle power supply system and supports continuous operation in an environment of -20℃.
