Description

Technical Field

[0001] This utility model relates to the field of locomotive electrical fault monitoring application technology, specifically a thermal imaging equipment installation structure for locomotive electrical fault monitoring. Background Technology

[0002] In existing technologies, locomotive electrical fault monitoring mainly relies on the Fire Protection Monitoring Subsystem (AFDR) within the 6A system. The 6A system is an onboard safety protection system designed for railway locomotives. This system performs real-time monitoring, alarming, and data recording of critical safety-critical components and systems, including the locomotive braking system, fire protection, high-voltage insulation, train power supply, running gear, and video surveillance. It is an integrated, platform-based safety protection system that integrates network transmission, unified solid-state storage, and intelligent human-machine interface interaction. The 6A system consists of six subsystems: Central Processing Platform (CPP), High-Voltage Insulation Detection Subsystem (AGDR), Locomotive Fire Protection Monitoring Subsystem (AFDR), Video Monitoring and Recording Subsystem (AVDR), Train Power Supply Monitoring Subsystem (APDR), Braking Safety Monitoring Subsystem (ABDR), and Running Gear Fault Monitoring Subsystem (ATDR). The Fire Protection Monitoring Subsystem (AFDR) is a subsystem of the 6A protection system and is a complete fire detector system, including fireproof cards (AF) and front-end fire detection equipment. This subsystem typically uses fixed-point detectors (such as smoke and temperature composite probes) to monitor the protected area of ​​the locomotive in real time and upload the status information to the 6A central control platform. Its deployment is relatively sparse, and the installation location often depends on experience, making it difficult to cover all the blind spots inside the electrical cabinet. In particular, the local temperature rise of sub-optimal components (such as electrical connectors and terminals) often cannot be effectively monitored.

[0003] Furthermore, the locomotive operating environment is complex, presenting challenges such as continuous vibration, dust, humidity, and oil contamination. The detectors used in the AFDR subsystem are typically designed with basic anti-vibration, dustproof, and moisture-proof features, making them prone to false alarms or damage under high-intensity vibration conditions, resulting in insufficient environmental adaptability. Additionally, their installation method is relatively fixed, making it difficult to adjust the monitoring angle once installed, leading to inconvenience in maintenance and calibration.

[0004] Therefore, there is an urgent need for a thermal imaging equipment installation structure that can adapt to the complex operating environment of locomotives, enable intensive monitoring, and is easy to maintain. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an installation structure for a thermal imaging device used for monitoring electrical faults in locomotives.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a thermal imaging equipment installation structure for monitoring electrical faults in locomotives, including a clamp bracket, the clamp bracket including a fixed base, a rotating adjustment frame and a flip adjustment plate, the rotating adjustment frame being detachably connected to the fixed base, the circumferential installation position of the rotating adjustment frame relative to the fixed base being adjustable, and the flip adjustment plate being hinged to the rotating adjustment frame. This design allows the connecting cover to be flipped and adjusted, thereby enabling the installed thermal imaging equipment to be rotated and flipped. The flip-up adjustment plate is bolted with a connecting cover that secures the main body of the thermal imaging device. This connecting cover has a single-sided open shell structure, which allows the thermal imaging device to be housed within, providing excellent dust and moisture protection and effectively protecting the delicate components inside. Simultaneously, the connecting cover also manages and protects cables, organizing them internally to prevent exposure and resulting in a neater and more organized installation.

[0007] Preferably, the fixed base includes a fixed base plate and a support cylinder. The back of the fixed base plate is recessed in the middle with an arc-shaped fitting surface that is adapted to the outer wall of the tube structure. The support cylinder is fixedly connected to the front of the fixed base plate. This fitting design allows the fixed base to fit tightly with the preset round tube or frame on the top of the electrical cabinet, increasing the contact area and improving the stability of the fixation.

[0008] Preferably, the base plate has several pairs of fixing holes, each pair of fixing holes is symmetrically distributed on both sides of the arc-shaped mating surface of the base plate, and each pair of fixing holes is fitted with a clamp ring. The fixing base of the clamp bracket is fixed to the pre-set round tube or frame on the top of the locomotive electrical cabinet through the clamp ring. This fixing method is simple and reliable, and at the same time, it makes it easy to install on the locomotive.

[0009] Preferably, the rotating adjustment frame includes a connecting cylinder and a support frame. The support frame has a U-shaped cross-section. The connecting cylinder is fixed to the bottom of the support frame. Both the connecting cylinder and the support cylinder are cylindrical structures. The end of the connecting cylinder away from the support frame is inserted into the support cylinder. Two circumferential positioning bolts are installed between the connecting cylinder and the support cylinder for fixation.

[0010] Preferably, the support cylinder has two symmetrical arc-shaped grooves about its central axis on its circumferential wall. The total arc length of the two arc-shaped grooves is equal to half the circumference of the support cylinder. The connecting cylinder has four locking screw holes radially on its wall. The four locking screw holes are located on the same cross-section and are evenly distributed at 90° intervals along the circumference. Two circumferential positioning bolts are respectively inserted into the two grooves and threaded into two of the locking screw holes. Both circumferential positioning bolts can be slidably adjusted along the grooves and are fixed relative to the connecting cylinder when tightened. By opening two arc-shaped grooves on the support cylinder and four locking screw holes on the connecting cylinder, and relying on two circumferential positioning bolts for fixation, the connecting cylinder can be rotated and adjusted within a 180° range without completely separating the connecting cylinder from the support cylinder. After adjusting to the required angle, the bolts can be tightened to fix it. This convenient operation method greatly reduces the time and effort required for equipment adjustment and improves the efficiency of equipment installation and commissioning.

[0011] Preferably, the flip adjustment plate has an inverted "U" shaped structure, including two side arms and a top wall connecting the two side arms. The two side arms are respectively hinged to the support frame by pins. The axial direction of the pins is limited and fixed by fastening bolts. The connecting cover is fixed to the top wall by bolts. The two side arms of the flip adjustment plate are hinged to the support frame by pins. This connection method not only realizes the flip adjustment function, but also ensures the reliability of the connection.

[0012] The beneficial effects of this utility model are: (1) The present invention describes a thermal imaging device installation structure for monitoring electrical faults in locomotives. This installation structure includes a clamp bracket, wherein a rotating adjustment frame is detachably connected to a fixed base, and the circumferential installation position of the rotating adjustment frame relative to the fixed base is adjustable.

This design allows the connecting cover to be flipped and adjusted, thereby enabling the installed thermal imaging device to be rotated and flipped. In practical applications, the internal structure of the locomotive electrical system is complex, and the electrical components are distributed in various locations. Through this multi-angle adjustment function, the thermal imaging device can flexibly adjust the detection angle to ensure accurate alignment with the electrical components to be monitored, such as electrical connectors, wiring terminals, and other critical parts. This helps improve the accuracy of fault monitoring and avoids blind spots caused by fixed installation angles. Simultaneously, this adjustability provides great convenience during equipment maintenance and calibration. Maintenance personnel can easily adjust the monitoring angle of the thermal imaging device, facilitating cleaning, inspection, and calibration operations without disassembling the entire installation structure, saving maintenance time and effort and improving equipment maintenance efficiency.

[0013] (2) The installation structure for a thermal imaging device for monitoring electrical faults in locomotives described in this utility model includes a connecting cover for mounting the thermal imaging device. The connecting cover is a single-sided open shell structure, which can house the thermal imaging device. In the locomotive operating environment, there are factors such as dust and moisture. The connecting cover can play a good role in dust and moisture prevention, effectively protecting the precision components inside the thermal imaging device and extending the service life of the device. At the same time, the connecting cover can also manage and protect the cables. Without the connecting cover, the cables may be exposed and easily damaged by external forces or worn by locomotive vibrations. It may also lead to messy cables, affecting the cleanliness and aesthetics of the device. The connecting cover can arrange the cables reasonably inside, avoiding cable exposure, making the entire device installation cleaner and more orderly, thereby effectively maintaining the overall environment of the locomotive electrical system and reducing the risk of faults caused by cable problems.

The simple structure makes it easy to install on the locomotive, and can achieve a dense installation layout according to the internal space of the locomotive electrical cabinet and the distribution of electrical components. The thermal imaging equipment of this installation structure, through dense layout and flexible viewing angle adjustment, can achieve more comprehensive and accurate monitoring of the inside of the electrical cabinet, improve the reliability of locomotive electrical fault monitoring, and provide a stronger guarantee for the safe operation of the locomotive.

[0015] (4) The installation structure of the thermal imaging equipment for monitoring electrical faults in locomotives described in this utility model includes a fixed base plate and a support cylinder for the fixing base of the clamp bracket. The back of the fixed base plate has an arc-shaped fitting surface that is adapted to the outer wall of the tube structure.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-6As shown, the installation structure of a thermal imaging device for monitoring electrical faults in locomotives according to this utility model includes a clamp bracket 1. The clamp bracket 1 includes a fixed base 4, a rotating adjustment frame 5, and a flip adjustment plate 6. The rotating adjustment frame 5 is detachably connected to the fixed base 4, and its circumferential installation position relative to the fixed base 4 is adjustable. The flip adjustment plate 6 is hinged to the rotating adjustment frame 5. This design allows the connecting cover 3 to be flipped and adjusted, thereby enabling the installed thermal imaging device to be rotated and flipped. In practical applications, the internal structure of locomotive electrical systems is complex, and the electrical components are distributed in various locations. Through this multi-angle adjustment function, the thermal imaging device can flexibly adjust the detection angle to ensure accurate alignment with the electrical components to be monitored, such as electrical connectors, wiring terminals, and other critical parts. This helps improve the accuracy of fault monitoring and avoids monitoring blind spots caused by a fixed installation angle. At the same time, this adjustability also provides great convenience during equipment maintenance and calibration. Maintenance personnel can easily adjust the thermal imaging device to a suitable position for cleaning, inspection, calibration, and other operations without disassembling the equipment, saving maintenance time and effort and improving equipment maintenance efficiency. In practical applications, the fixed base 4, rotating adjustment frame 5, and flip adjustment plate 6 of the clamp bracket 1 are made of aluminum alloy and the surface is treated with anti-oxidation paint, which has corrosion resistance and rust prevention capabilities. The flip-up adjustment plate 6 is bolted to a connecting cover 3 that secures the main body of the thermal imaging equipment. The connecting cover 3 has a single-sided open shell structure, allowing the thermal imaging equipment to be housed within it. In the locomotive operating environment, dust and moisture are present; the connecting cover 3 provides excellent dust and moisture protection, effectively protecting the precision components inside the thermal imaging equipment and extending its service life. Simultaneously, the connecting cover 3 also manages and protects the cables. Without the connecting cover 3, cables may be exposed, making them susceptible to damage from external forces or wear from locomotive vibrations. This can also result in messy cables, affecting the cleanliness and aesthetics of the equipment. The connecting cover 3 allows for the orderly arrangement of cables internally, preventing exposure and ensuring a neater and more organized installation. This is crucial for maintaining the overall environment of the locomotive's electrical system and reducing the risk of malfunctions caused by cable issues.

[0026] A further improvement in this embodiment is that the fixed base 4 includes a fixed base plate 401 and a support cylinder 403. The fixed base plate 401 has an arc-shaped fitting surface recessed in the center of its back side, which is adapted to the outer wall of the tube structure. The support cylinder 403 is fixedly connected to the front side of the fixed base plate 401. This fitting design allows the fixed base 4 to fit tightly against the pre-set circular tube or frame on the top of the electrical cabinet, increasing the contact area and improving the stability of the fixation. During locomotive operation, it will face various complex road conditions and vibration environments. This structural setting of the fixed base 4 can firmly fix it to the pre-set circular tube or frame on the top of the electrical cabinet, effectively improving the seismic resistance of the entire installation structure. Even under conditions of large locomotive vibration, it can ensure the stable installation of the thermal imaging equipment, preventing the equipment from loosening or shifting due to vibration, thereby ensuring the accuracy of monitoring data and the normal operation of the equipment.

[0027] A further improvement in this embodiment is that the fixed base plate 401 has several pairs of fixing holes 402, each pair of fixing holes 402 being symmetrically distributed on both sides of the arc-shaped contact surface of the fixed base plate 401. Each pair of fixing holes 402 is fitted with a clamping ring 2. The fixing base 4 of the clamping bracket 1 is fixed to the pre-set circular tube or frame on the top of the locomotive electrical cabinet via the clamping ring 2. This fixing method is simple and reliable, and allows for convenient installation on the locomotive. The clamping ring 2 is made of stainless steel, possessing sufficient mechanical strength and corrosion resistance. Through the anti-loosening bolt rotation and tightening design, the installation structure can be firmly locked onto the pre-set circular tube or frame on the top of the electrical cabinet, forming the main load-bearing support point. It connects with the main load-bearing structure of the circular tube / frame inside the cabinet, improving vibration resistance. In practical applications, if the installation location is flat and has mounting holes, the clamping ring 2 is not required; only bolts passing through the fixing holes 402 and mounting holes are needed for fixing. Furthermore, the fixing holes 402 adopt a highly compatible empty hole design, suitable for mounting in most monitoring equipment camera positions.

[0028] A further improvement in this embodiment is that the rotating adjustment frame 5 includes a connecting cylinder 501 and a support frame 503. The support frame 503 has a U-shaped cross-section. The connecting cylinder 501 is fixed to the bottom of the support frame 503. Both the connecting cylinder 501 and the support cylinder 403 are cylindrical structures. The end of the connecting cylinder 501 away from the support frame 503 is inserted into the support cylinder 403. Two circumferential positioning bolts 7 are installed between the connecting cylinder 501 and the support cylinder 403 for fixation.

[0029] A further improvement in this embodiment is that the support cylinder 403 has two symmetrical arc-shaped channels 404 about its central axis on its circumferential wall. The total arc length of the two arc-shaped channels 404 is equal to half the circumference of the support cylinder 403. The connecting cylinder 501 has four locking screw holes 502 radially on its wall. The four locking screw holes 502 are located on the same cross-section and are evenly distributed at 90° intervals along the circumferential direction. Two circumferential positioning bolts 7 are respectively inserted into the two channels 404 and threaded into two of the locking screw holes 502. Both circumferential positioning bolts 7 can slide and adjust along the groove 404 and are fixed relative to the connecting cylinder 501 when tightened. Two arc-shaped grooves 404 are provided on the support cylinder 403, and four locking screw holes 502 are provided on the connecting cylinder 501. The two circumferential positioning bolts 7 provide fixation, allowing the connecting cylinder 501 to rotate and adjust within a 180° range without completely detaching it from the support cylinder 403. Once the desired angle is achieved, the bolts can be tightened to secure it. This convenient operation significantly reduces the time and effort required for equipment adjustment, improving the efficiency of equipment installation and commissioning. This design is particularly advantageous when the equipment requires frequent angle adjustments.

[0030] A further improvement in this embodiment is that the tilting adjustment plate 6 has an inverted "U"-shaped structure, including two side arms and a top wall connecting the two side arms. The two side arms are hinged to the support frame 503 via pins, and the axial direction of the pins is limited and fixed by fastening bolts 8. The connecting cover 3 is fixed to the top wall by bolts. The two side arms of the tilting adjustment plate 6 are hinged to the support frame 503 via the pins. This connection method not only realizes the tilting adjustment function but also ensures the reliability of the connection. The axial direction of the pins is limited and fixed by the fastening bolts 8. This limiting design prevents the pins from shifting during vibration, further enhancing the stability of the connection. This stable connection method allows the tilting adjustment plate 6 to maintain a good working condition during long-term use, reducing the risk of failure caused by loose connections.

[0031] In use, first, secure the thermal imaging device body to the connecting cover 3. Use Phillips head screws to firmly install the thermal imaging device body inside the connecting cover 3. The connecting cover 3 has a single-sided open shell structure, which facilitates the installation and removal of the thermal imaging device body. During installation, ensure the screws are tightened evenly to guarantee the stability of the thermal imaging device body inside the connecting cover 3. The connecting cover 3 not only secures the thermal imaging device but also protects it from damage caused by dust and moisture. It also manages and protects cables, making the entire installation neater and more organized.

[0032] Then, the connecting cover 3 is fixed to the flip-adjustment plate 6 of the clamp bracket 1. Using Phillips head screws, the top wall of the connecting cover 3 is fixedly connected to the top wall of the flip-adjustment plate 6. The flip-adjustment plate 6 has an inverted "U" shape, including two side arms and a top wall connecting the two side arms. This structural design gives the flip-adjustment plate 6 good stability and strength, enabling it to withstand the weight of the thermal imaging equipment and achieve flexible flip-adjustment. The thermal imaging equipment can be flipped and adjusted at multiple angles through the flip-adjustment plate 6, facilitating adjustments to the equipment's orientation according to actual monitoring needs.

[0033] Finally, the clamp bracket 1 is fixed to the main load-bearing structure of the round tube or frame at the top of the locomotive electrical cabinet. The fixing base plate 401 of the fixing base 4 has a recessed arc-shaped contact surface in the center of its back, which adapts to the outer wall of the tube structure. This design allows the fixing base 4 to fit tightly against the pre-set round tube or frame at the top of the electrical cabinet. Several pairs of fixing holes 402 are provided on the fixing base plate 401, each pair of holes 402 being symmetrically distributed on both sides of the arc-shaped contact surface of the fixing base plate 401. A clamp ring 2 passes through each pair of fixing holes 402. The fixing base 4 is securely fixed to the round tube or frame using the clamp rings 2. This fixing method is simple and reliable, ensuring the stability of the clamp bracket 1 during locomotive operation and guaranteeing the normal operation of the thermal imaging equipment even in environments with significant vibration. After installation, the detection angle of the thermal imaging equipment can be further adjusted using the adjustment functions of the rotating adjustment frame 5 and the flip adjustment plate 6, ensuring that the equipment can accurately align with the electrical components to be monitored.
