Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted measuring devices, in particular to a vehicle-mounted measuring device capable of measuring the temperature of entire contact network components without blind spots. Background Art

[0002] With the rapid acceleration of my country's railways and the development of high-speed railways and passenger-dedicated lines, the overhead catenary system (OCS) plays a crucial role in electrified railways. As the core power supply infrastructure of electrified railways, its operational status directly impacts train safety and operational efficiency. Over long-term operation, OCS components (such as contact wires, load-bearing cables, insulators, and clamps) accumulate heat due to current flow, mechanical friction, and environmental changes (such as high temperatures, rain, snow, and contamination). Abnormally high temperatures can lead to thermal aging of equipment, degradation of electrical performance, and even fire. Therefore, comprehensive temperature monitoring of all OCS components is a critical requirement for ensuring safe railway operations.

[0003] The prerequisite for measuring abnormal heating of contact network components is that abnormal heating (heat) occurs when current flows through the contact network. Currently, the main method for measuring abnormal heating of contact network components onboard is to install the device on the operating vehicle. The device runs with the operating vehicle to complete the abnormal heating of the contact network components. Within the same power supply arm, due to different current flows, detection can only be performed when the contact network current flows in a direction different from the direction of vehicle movement. When the contact network current flows in the same direction as the vehicle movement or is blocked by the pantograph, it is difficult to monitor abnormal heating of the contact network, forming a detection blind spot. In addition, when the train is running, dust accumulated on the lens surface may absorb the infrared radiation emitted by the contact network surface, thereby reducing the radiation energy received by the infrared temperature monitor and affecting the measurement results.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle-mounted measuring device that covers the temperature of the entire contact network components without blind spots, so as to solve the problem in the above-mentioned background technology that when the direction of the contact network current flows in the same direction as the direction of movement of the vehicle or is blocked by the pantograph, a detection blind spot will be formed, which makes it inconvenient to monitor abnormal heating of the contact network. The dust accumulated on the surface of the lens may absorb the infrared radiation emitted by the surface of the contact network, affecting the measurement results.

[0007] Preferably, the pantograph is installed in the top area near the middle of the base plate, and the infrared detector is installed in the area between the pantograph and the side end of the top of the base plate. The number of the pantographs and infrared detectors is two groups, and the two groups of pantographs and infrared detectors are symmetrically distributed at the top of the base plate.

[0008] Preferably, the cover is mounted on the outside of the infrared detector, a circular transparent baffle is mounted on the surface of the cover, and a mounting plate is mounted on the surface of the cover.

[0009] Preferably, an arc-shaped groove is provided inside the first adjustment ring, and the scraper surface protrusion slides within the arc-shaped groove inside the first adjustment ring. The number of the scrapers and arc-shaped grooves is six, and they are evenly distributed in a circular shape inside the rotating ring.

[0010] Preferably, the side end of the moving block is rotatably connected to a convex ring, the side end of the convex ring is elastically connected to a pneumatic suction head, and the side surface of the pneumatic suction head close to one end of the cover shell contacts the inner side of the scraper.

[0011] Preferably, the other end of the adjustment plate slides within the second adjustment ring, and the number of the adjustment plates is six groups, which are distributed in a circular shape on the surface of the pneumatic suction head close to one end of the cover.

[0012] Preferably, the pneumatic suction head is installed with a long plate near the surface of one end of the cover shell, and an oil tank is installed on the surface of the long plate. A second piston rod is sliding in a limited position inside the oil tank, and a spherical shaft is connected to the end of the second piston rod. The spherical shaft at the end of the second piston rod slides in a limited position at the bottom end of the long plate at the side end of the second adjustment ring, and a hose is connected between the oil cavity and the oil tank.

[0013] Preferably, the number of the push rods is six groups, and the six groups of push rods are distributed in a circular shape inside the connecting plate. Springs are sleeved on the surfaces of the push rods, and the surface of the resistance ring close to the connecting plate is concave and convex.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention installs an infrared detector on the outside of two pantographs (i.e., behind the current-collecting pantograph). Regardless of whether the current direction is in the same direction or opposite to the locomotive's running direction, the infrared detector will not be affected by the pantograph's obstruction. The locomotive can pass through once to achieve full coverage of abnormal temperature rise detection of contact network components in the operating section. This enables the infrared detector to be unaffected by the pantograph's obstruction and fully cover all components of the contact network, including those areas that are difficult to reach with traditional detection methods, thereby ensuring the comprehensiveness and accuracy of the detection.

[0016] 2. The present invention, through the provision of a rotating cleaning component, can clean the dust accumulated on the surface of the cover when the train is running, thereby preventing the dust from absorbing the infrared radiation emitted by the surface of the contact network and affecting the measurement results. When the train is running at high speed, dust is more likely to accumulate on the surface of the cover. The rotating cleaning component can continuously clean the dust during the operation of the train, ensuring that the infrared detector can still maintain stable performance in a high-speed operation environment, reducing the measurement error caused by dust accumulation, and improving the effect of real-time monitoring of the contact network status.

[0017] 3. The present invention, through the provision of a shaking dust collection assembly, can simultaneously clean the cover dust while the train is running, thus preventing the rotating cleaning assembly from obstructing the infrared detector during operation and affecting the measurement effect. By avoiding obstruction interference, the infrared detector can continuously and stably measure during the train operation. The shaking dust collection assembly, through the dual effects of shaking and dust collection, can more effectively remove dust from the cover surface. Compared with traditional cleaning methods, it can clean dust more thoroughly and reduce dust interference with infrared radiation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-13 The present invention provides a technical solution: a vehicle-mounted measuring device for measuring the temperature of the entire contact network components without blind spots, comprising a base plate 1, a pantograph 2 installed on the top of the base plate 1, an infrared detector 3 installed on the top of the base plate 1, a cover shell 4 installed on the top of the base plate 1, a first adjusting ring 6 provided on the surface of the cover shell 4, a rotating ring 7 rotatably connected to the inner wall of the first adjusting ring 6, a scraper 8 rotatably connected to the inside of the rotating ring 7, a moving block 9 slidingly limited in a slide groove on the surface of the scraper 8, a rotating cleaning component installed on the outer surface of the first adjusting ring 6, a pneumatic suction head 11 provided on the side end of the moving block 9, a shaking dust collection component provided on the end of the pneumatic suction head 11, and a convex plate 13 installed on the surface of the scraper 8; The shaking dust collection assembly includes an oil chamber 121 installed inside the scraper 8, and a first piston rod 122 is limited in sliding inside the oil chamber 121. The pneumatic suction head 11 is rotatably connected to one end of the cover shell 4 with a second adjusting ring 124. A groove is provided near the bottom end of the cover shell 4 with an adjusting plate 125 for limited sliding inside the groove. A connecting plate 128 is installed inside the cover shell 4, and a push rod 129 is limited in sliding inside the connecting plate 128. A resistance ring 1210 is rotatably connected near the inner wall position of the cover 4, and a fourth piston rod 1211 is installed on the inner wall of the cover 4. The protruding end of the fourth piston rod 1211 is limited in sliding in the bottom groove of the back end protrusion of the resistance ring 1210 through a spherical shaft, which can synchronously clean the dust on the cover 4 when the train is running, and can avoid the rotating cleaning assembly from blocking the infrared detector 3 when it is in operation.

[0022] As an embodiment of the present invention, a pantograph 2 is installed in the top of the base plate 1 near the middle area, and an infrared detector 3 is installed in the area between the pantograph 2 and the side end of the top of the base plate 1. The number of pantographs 2 and infrared detectors 3 is two, and the two groups of pantographs 2 and infrared detectors 3 are symmetrically distributed on the top of the base plate 1. The temperature measuring camera is installed on the outside of the two pantographs 2 (i.e., behind the current collecting pantographs 2). Regardless of whether the current direction is in the same direction as or opposite to the locomotive running direction, the temperature measuring camera will not be blocked by the pantograph 2. As an embodiment of the present invention, a cover 4 is mounted on the outside of the infrared detector 3, a circular transparent baffle is mounted on the surface of the cover 4, and a mounting plate 5 is mounted on the surface of the cover 4. The design of the circular transparent baffle can block external dust, thereby preventing external dust from contacting the lens of the infrared thermometer; As an embodiment of the present invention, an arc-shaped chute is provided inside the first adjustment ring 6, and a protrusion on the surface of the scraper 8 slides within the arc-shaped chute inside the first adjustment ring 6. The number of scrapers 8 and arc-shaped chute is six, and they are evenly distributed in a circular shape inside the rotating ring 7. The gear ring can drive the first adjustment ring 6 and the rotating ring 7 to rotate, thereby driving the scraper 8 to clean the surface of the circular transparent baffle; As an embodiment of the present invention, the side end of the moving block 9 is rotatably connected to a convex ring 123, and the side end of the convex ring 123 is elastically connected to a pneumatic suction head 11. The side surface of the pneumatic suction head 11 close to one end of the cover 4 contacts the inner side of the scraper 8. The pneumatic suction head 11 contacts the inner side of the scraper 8 and can absorb the dust removed by the scraper 8, thereby preventing the cleaned dust from being adsorbed again on the surface of the circular transparent baffle. As an embodiment of the present invention, the other end of the adjustment plate 125 is limited and slides inside the second adjustment ring 124. The number of the adjustment plates 125 is six. The six groups of adjustment plates 125 are distributed in a circular shape on the surface of the end of the pneumatic suction head 11 close to the cover 4. The establishment of the adjustment plates 125 can adjust the diameter of the pneumatic suction head 11, thereby improving the suction force of the pneumatic suction head 11 and cleaning the dust in the middle of the circular transparent baffle. When the contact network current flows in the same direction as the direction of vehicle movement or is blocked by the pantograph 2, a detection blind spot will be formed, which makes it inconvenient to monitor abnormal heating of the contact network. The dust accumulated on the lens surface may absorb the infrared radiation emitted by the contact network surface, affecting the measurement results. The specific implementation method is as follows: when working, the controller first drives the rotating ring 7 to rotate inside the first adjusting ring 6 through the first electric push rod 101. When the rotating ring 7 rotates, it drives the scraper 8 to rotate and extend inside the rotating ring 7, and then drives the second electric push rod 101 through the controller. 04 protruding end drives the tooth plate 105 to descend. At this time, the tooth plate 105 descends and drives the gear ring 102 to rotate clockwise on the surface of the cover 4. The clockwise rotation of the gear ring 102 drives the first adjusting ring 6 and the rotating ring 7 to rotate together. The rotation of the rotating ring 7 drives the scraper 8 to rotate on the circular transparent baffle on the surface of the cover 4. Then, when the distance sensor 103 detects that the tooth plate 105 moves downward, it will drive the extended end of the third electric push rod 106 through the controller to drive the moving block 9 to move. When the moving block 9 moves in the slide groove on the surface of the scraper 8, the controller drives the pneumatic suction head 11 Working, it absorbs the dust cleaned by the scraper 8. When the moving block 9 moves on the surface of the scraper 8, when the convex ring 123 contacts the convex plate 13, the convex plate 13 drives the pneumatic suction head 11 to deflect. At this time, the moving block 9 will synchronously squeeze the first piston rod 122, and inject the oil inside the oil cavity 121 into the oil tank 126. The oil inside the oil tank 126 pushes the second piston rod 127 to extend. The output end of the second piston rod 127 drives the second adjusting ring 124 to rotate on the surface of the pneumatic suction head 11 close to the cover 4. The second adjusting ring 1 24 drives the adjustment plate 125 to slide in the slide groove on the surface of the end of the pneumatic suction head 11 close to the cover 4 to adjust the diameter of the pneumatic suction head 11. At this time, the controller drives the extended end of the fourth piston rod 1211 to reciprocate and extend. The extended end of the fourth piston rod 1211 drives the contact ring 1210 to rotate inside the cover 4. The contact ring 1210 contacts the bottom of the push rod 129, driving the end of the push rod 129 to hit the circular transparent baffle on the surface of the cover 4, raising dust on its surface. The raised dust is then absorbed by the deflected pneumatic suction head 11. As an embodiment of the present invention, the pneumatic suction head 11 is provided with a long plate installed on the surface of one end of the cover 4, and an oil tank 126 is installed on the surface of the long plate. A second piston rod 127 is limited and slides inside the oil tank 126, and the end of the second piston rod 127 is connected to a spherical shaft. The spherical shaft at the end of the second piston rod 127 slides within the bottom end of the long plate at the side end of the second adjusting ring 124. A hose is connected between the oil cavity 121 and the oil tank 126. There are six groups of push rods 129, and the six groups of push rods 129 are distributed in a circular shape inside the connecting plate 128. A spring is provided on the surface of the push rod 129, and the surface of the contact ring 1210 close to the connecting plate 128 is concave and convex. The rotation of the contact ring 1210 can drive the push rod 129 to slap the circular transparent baffle, so that dust on the surface of the circular transparent baffle flies, thereby improving the dust adsorption capacity of the pneumatic suction head 11; As an embodiment of the present invention, the rotating cleaning assembly includes a first electric push rod 101 installed at the top of the long plate on the surface of the first adjustment ring 6, and the protruding end of the first electric push rod 101 is limited and slid in the groove at the bottom end of the long plate on the surface of the rotating ring 7 through a spherical shaft, and also includes a gear ring 102 rotating on the surface of the cover 4, and the outer surface of the first adjustment ring 6 rotates inside the gear ring 102. A distance sensor 103 is installed on the surface of the cover 4, and a second electric push rod 104 is installed on the surface of the cover 4. A tooth plate 105 is installed on the protruding end of the second electric push rod 104, and the tooth plate 105 is meshed with the gear ring 102. A third electric push rod 106 is installed inside the scraper 8, and the protruding end of the third electric push rod 106 is connected to the moving block 9. The rotating cleaning assembly can continuously clean dust during the operation of the train, ensuring that the infrared detector 3 can still maintain stable performance in a high-speed operation environment, reducing measurement errors caused by dust accumulation, and improving the effect of real-time monitoring of the contact network status.

[0023] Working principle: During cleaning, the controller first drives the rotating ring 7 to rotate inside the first adjusting ring 6 through the first electric push rod 101. When the rotating ring 7 rotates, the scraper 8 rotates and extends inside the rotating ring 7. Then, the controller drives the extended end of the second electric push rod 104 to drive the gear plate 105 to descend. At this time, the gear plate 105 descends and drives the gear ring 102 to rotate clockwise on the surface of the cover 4. The clockwise rotation of the gear ring 102 drives the first adjusting ring 6 and the rotating ring 7 to rotate together. The rotation of the rotating ring 7 drives the scraper 8 to rotate on the circular transparent baffle on the surface of the cover 4. Then, when the distance sensor 103 detects that the gear plate 105 moves downward, it will drive the extended end of the third electric push rod 106 through the controller to drive the moving block 9 to move. When the moving block 9 moves in the slide groove on the surface of the scraper 8, the controller drives the pneumatic suction head 11 to work to absorb the dust cleaned by the scraper 8. When the moving block 9 moves on the surface of the scraper 8, the convex ring 123 contacts the convex plate 13. When the pneumatic suction head 11 is deflected, the convex plate 13 drives the pneumatic suction head 11 to deflect. At this time, the moving block 9 will synchronously squeeze the first piston rod 122, and the oil in the oil chamber 121 is injected into the oil tank 126. The oil in the oil tank 126 pushes the second piston rod 127 to extend. The output end of the second piston rod 127 drives the second adjusting ring 124 to rotate on the surface of the pneumatic suction head 11 close to the end of the cover 4. The second adjusting ring 124 drives the adjusting plate 125 to slide in the slide groove on the surface of the pneumatic suction head 11 close to the end of the cover 4 to adjust the diameter of the pneumatic suction head 11. At this time, the controller drives the extended end of the fourth piston rod 1211 to reciprocate and telescopic motion. The extended end of the fourth piston rod 1211 drives the contact ring 1210 to rotate inside the cover 4. The contact ring 1210 contacts the bottom of the push rod 129, driving the end of the push rod 129 to slap the circular transparent baffle on the surface of the cover 4, raising dust on its surface, and the raised dust is adsorbed by the deflected pneumatic suction head 11; When the controller drives the extended end of the second electric push rod 104 to move upward, the controller drives the fourth piston rod 1211 to stop operating. At the same time, the controller drives the extended end of the third electric push rod 106 to retract and drive the moving block 9 to reset. When the moving block 9 is reset, the convex plate 13 drives the convex ring 123 to rotate to make the pneumatic suction head 11 return to the center. The first piston rod 122 loses its squeeze under the force of the spring rebound, so that the oil inside the oil tank 126 is injected into the oil cavity 121. At this time, the second piston rod 127 moves downward inside the oil tank 126, which will pull the second adjusting ring 124 to rotate on the surface of one end of the pneumatic suction head 11 close to the cover 4, so that the diameter of the pneumatic suction head 11 changes to its original state. Then the controller drives the extended end of the first electric push rod 101 to retract, so that the swivel 7 rotates inside the first adjusting ring 6, driving the scraper 8 to rotate and recycle inside the swivel 7.
