Description

Technical Field

[0001] The invention relates to the technical field of infrared thermal imaging equipment, and more specifically, to an infrared thermal imaging device for temperature monitoring of electric power equipment. Background Art

[0002] Infrared thermal imaging device is an advanced detection equipment. Its working principle is based on the characteristic that all objects above absolute zero will emit infrared radiation. The infrared detector captures these radiations and converts the received infrared radiation into electrical signals. After signal processing, the imaging system converts them into visible thermal images with different colors representing different temperatures.

[0003] At present, infrared thermal imaging devices have a wide range of applications. For example, in the power industry, infrared thermal imagers can be used to monitor the temperature of related power equipment such as transformers and switch cabinets in operation in real time, and overheating faults can be discovered in time. In the prior art, such as the publication number CN115326209A, a temperature monitoring sensor system and method for power equipment using infrared thermal imaging technology are disclosed, wherein the rotating moving device includes a hot-jointed elbow, an automatic reset mechanism is provided on the surface of the hollow rod, the output end of the driving motor is fixedly connected to a rotating shaft, the surface of the rotating shaft is symmetrically fixedly sleeved with a sixth bevel gear, one end of the connecting column is fixedly connected to a second ring, and the surface of the rotating shaft is symmetrically fixedly connected to a gear lever. The temperature monitoring sensor system and method for power equipment using infrared thermal imaging technology solves the problem that it is impossible to achieve simultaneous movement up, down, left, and right, increases the shooting range of the camera, thereby reducing the blind spot of the viewing angle, and avoids the phenomenon that power equipment at the corner cannot be photographed. In addition, the phenomenon that automatic reset and movement cannot be achieved when moving up, down, left, and right through gears and screws is also impossible.

[0004] However, in the actual power equipment monitoring scenario, when the infrared thermal imaging device is deployed to monitor the back of multiple power equipment at the same time, its lens is facing the back of the power equipment and is installed close to the back of the power equipment based on the monitoring needs. Although the above-mentioned temperature monitoring sensor system has the ability to move at multiple angles and can achieve all-round monitoring of multiple power equipment, it cannot be ignored that since the back of the power equipment is often where the heat dissipation window is located, during the operation of the equipment, the flow of heat dissipation airflow is very likely to cause dust, and these dusts will adhere to the lens end face of the infrared thermal imaging device irregularly, and as time goes by and the dust situation intensifies, when the dust adsorbed on the lens accumulates to a certain extent, it will have a significant negative impact on the monitoring accuracy of the infrared thermal imaging device, thereby interfering with the accurate judgment and monitoring of the operating status of the power equipment.

[0040] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0041] Please refer to Figure 1 to Figure 2, an infrared thermal imaging device for monitoring the temperature of electric equipment, comprising: a thermal imager body 1, a support mechanism 2, a rotation drive mechanism 3 and a maintenance mechanism 4. The support mechanism 2 comprises a support seat 201 and a mounting assembly, wherein the thermal imager body 1 is mounted on the top of the support seat 201, wherein the thermal imager body 1 mainly captures the radiation generated by the electric equipment through an infrared detector, thereby realizing the temperature monitoring of the electric equipment, which belongs to the prior art, so its specific structure and model are not limited here. The bottom of the support seat 201 is rotatably connected to the top surface of the mounting assembly, and the mounting assembly is used to be fixed to a preset installation position, and can be fixed with a fastening bolt. The rotation drive mechanism 3 is arranged on the mounting assembly, and its driving end is connected to the rotating end at the bottom of the support seat 201. The rotation drive mechanism 3 drives the support seat 201 to perform forward and reverse actions according to a preset angle cycle, so that the thermal imager body 1 can regularly inspect the electric equipment at different positions, and the forward and reverse angle range can be selected according to the actual situation, generally within 180 degrees. An adjustment component 7 is also provided at the upper end of the support base 201 , and the adjustment component 7 is used to adjust the tilt angle of the thermal imager body 1 so that the thermal imager body 1 can meet different usage requirements of tilt angles.

[0042] Please refer to Figure 3 The maintenance mechanism 4 includes a rocker arm 402, a contact scraper assembly and a lifting assembly. The contact scraper assembly is slidably arranged on one side of the lens of the thermal imager body 1. The rocker arm 402 is rotatably installed on one side of the thermal imager body 1, and one end thereof is slidably connected with the end of the contact scraper assembly. The lifting assembly is installed on the support seat 201, and its end is hinged to the other end of the rocker arm 402. After the lifting assembly rotates to a preset position following the support seat 201, an upward thrust is generated on the rocker arm 402, so that the contact scraper assembly slides linearly along the end surface of the lens of the thermal imager body 1.

[0043] It should be noted that when the above-mentioned infrared thermal imaging device is in use, under normal conditions, the thermal imager body 1 is in a stationary state, and the temperature of the back of the power equipment is normally monitored by the thermal imager body 1. When it is necessary to inspect the power equipment, please refer to Figure 3As shown, assuming that the preset rotation angle is 120 degrees, at this time, the support base 201 can be driven to rotate in the clockwise direction first by the rotation drive mechanism 3, and the infrared thermal imager and the maintenance mechanism 4 rotate to the right along with the support base 201. After rotating 60 degrees, the support base 201, the thermal imager body 1 and the maintenance mechanism 4 rotate to the left together. Before rotating 120 degrees, the lifting component generates an upward thrust on the swing rod 402, which can drive the swing rod 402 to rotate. The contact scraping component starts to slide downward along the end surface of the lens of the thermal imager body 1 under the driving action of the swing rod 402, and then scrapes off the dust adsorbed on its end surface. After the support base 201 rotates 120 degrees, the contact scraping component just slides to the end of the imager body. At the lower end of the surface, the dust is also scraped off and separated, completing a dust cleaning action. Afterwards, under the continued driving action of the rotating drive mechanism 3, the support seat 201 begins to rotate in the counterclockwise direction, and the contact scraping component synchronously moves up and slides to reset along the end surface of the thermal imager body 1 to perform dust cleaning again. In this way, the automatic cleaning operation of the end surface of the thermal imager body 1 is completed simultaneously during the inspection, realizing the linkage function of the inspection and cleaning of the thermal imager body 1, which will not affect the normal progress of the inspection. The mechanism of regular inspection can also ensure an effective cleaning frequency, solve the problem of the negative impact of dust on the detection accuracy of the end surface of the lens of the thermal imager body 1, so as to realize the accurate judgment and monitoring function of the operating status of the power equipment.

[0044] In addition, in order to avoid the contact scraping component affecting the thermal imager body 1 during dust cleaning, the timing of the lifting component activity should be selected outside the effective monitoring range of the thermal imager body 1. If the preset rotation angle of the thermal imager body 1 is 120 degrees and the effective monitoring range is 100 degrees, the lifting component activity should be after 100 degrees.

[0045] Please refer to Figure 3 to Figure 4 The lifting assembly includes a movable rod 403, a supporting spring 404, a spherical roller 405, a connecting rod 406 and a lifting contact block 407 adapted to the spherical roller 405. The lower end of the movable rod 403 is slidably connected to the support seat 201, and the spherical roller 405 is installed on the bottom end of the movable rod 403. The supporting spring 404 is sleeved on the lower end of the movable rod 403, and its two ends are respectively fixed to the spherical roller 405 and the support seat 201. The two ends of the connecting rod 406 are respectively hinged to the upper end of the movable rod 403 and the end of the rocker rod 402. The lifting contact block 407 is fixedly installed on the top of the support seat 201. The lifting contact block 407 is located on the rolling path of the spherical roller 405. The lifting contact block 407 is an arc plate that drives the groove.

[0046] It should be noted that when the above-mentioned lifting assembly is in use, if it is necessary to adjust the inclination angle of the thermal imager body 1, when the thermal imager body 1 rotates, the rocker arm 402 also moves accordingly, and the connecting rod 406 moves synchronously under the driving action of the rocker arm 402, while the end of the movable rod 403 remains stationary. The movement of the connecting rod 406 is synchronously adapted to the movement of the rocker arm 402, so that the lifting assembly will not affect the adjustment action of the thermal imager body 1. After the adjustment is completed, the thermal imager body 1 can be fixed. When the thermal imager body 1 is rotating for inspection, the movable rod 403 and the spherical roller 405 rotate together with the support seat 201. At this time, the bottom of the spherical roller 405 rolls and contacts the top surface of the support seat 201. When the spherical roller 405 rolls and contacts the lifting contact block 407, the spherical roller 405 begins to roll along the groove of the lifting contact block 407 and is subjected to the upward lifting force of the lifting contact block 407, which can make the movable rod 403 slide upward and squeeze the support spring 404 to contract, and the connecting rod 406 is subjected to the lifting force of the movable rod 403, which can drive the swing rod 402 to rotate, thereby causing the contact scraping assembly to start sliding. In this way, through the coordinated linkage action between the maintenance mechanism 4 and the rotating drive mechanism 3, after the thermal imager body 1 reaches the preset angle, the maintenance mechanism 4 synchronously completes the automatic cleaning operation of its lens end face, and the automatic cleaning can be completed without separately setting a driving source and a control program, which will not increase the power consumption and use cost of the infrared thermal imaging device.

[0047] Please refer to Figure 3 to Figure 4 A shading hood 5 is fixedly installed at one end of the lens of the thermal imager body 1, and the contact scraping component is a contact scraper 401. The contact scraper 401 is arranged at the upper end of the inner side of the shading hood 5. A vertical groove 6 adapted to the end face of the thermal imager body 1 is provided on one side of the shading hood 5. One end of the contact scraper 401 is slidably connected to the inner side of the shading hood 5, and the other end thereof slides through the vertical groove 6 and is slidably connected with the end of the swing rod 402. One side of the contact scraper 401 is in sliding contact with the end face of the lens of the thermal imager body 1, and the side of the contact scraper 401 in contact with the end face of the lens of the thermal imager body 1 can be made of rubber to avoid wear on the end face of the lens.

[0048] Please refer to Figures 5 and 6 The rotating drive mechanism 3 includes a driving motor 301, an active rod 302, a transmission rod 303 and a passive rod 304. The driving motor 301 is fixedly mounted on one side of the mounting assembly. The active rod 302 is connected to the driving end of the driving motor 301. One end of the passive rod 304 is fixed to the rotating end of the support seat 201. The two ends of the transmission rod 303 are hinged to the ends of the passive rod 304 and the active rod 302 respectively.

[0049] It should be noted that when the rotary drive mechanism 3 is in use, the driving end of the driving motor 301 rotates in the clockwise direction, which can drive the active rod 302 to rotate, and then the transmission rod 303 generates a pulling force on the passive rod 304, so that the support seat 201 can start to rotate in the clockwise direction. When the active rod 302, the transmission rod 303 and the passive rod 304 rotate to a straight line position, the support seat 201 rotates to a maximum angle, and the driving motor 301 continues to drive. The transmission rod 303, under the driving action of the active rod 302, begins to generate a thrust on the passive rod 304, thereby driving the support seat 201 to rotate in the counterclockwise direction until the support seat 201 rotates to the maximum angle, and the transmission rod 303 again generates a thrust on the passive rod 304, so that the support seat 201 starts to rotate in the clockwise direction. By continuously rotating the driving motor 301, the support seat 201 can be turned over in a preset angle and perform forward and reverse actions, so that the thermal imager body 1 can inspect the power equipment within the effective range.

[0050] Please refer to Figure 7 Since the installation position of the infrared thermal imaging device is relatively narrow, when it needs to be repaired, it is difficult for the staff to perform the repair operation without moving the power equipment or contacting auxiliary tools. Therefore, in order to facilitate the staff to repair, the present invention continues to optimize the above scheme. The specific scheme is: the installation component includes a sliding base plate 202, a fixed plate 203 and an extension component. The sliding base plate 202 is slidably installed on one side of the fixed plate 203. Both sides of the fixed plate 203 are provided with limiting guide grooves 212. Both sides of the sliding base plate 202 are slidably connected with the limiting guide grooves 212 on the corresponding side through the sliding shaft 213. The extension component includes an extension connecting member and an extension driving member. The two ends of the extension connecting member are respectively slidably connected with the sliding base plate 202 and one side of the fixed plate 203. One end of the extension driving member is connected to the extension connecting member, and the other end thereof is transmission-connected with the driving end of the driving motor 301.

[0051] For details, please refer to Figures 7 to 9The extension drive member includes a transmission gear 204, a first ratchet 205, a second ratchet 206, a matching tooth plate 207 and two ratchet ring bodies 208. The transmission gear 204 is sleeved on the outer side of the driving end of the driving motor 301. A plurality of circumferentially evenly distributed support slides 214 are fixedly installed at the bottom of the transmission gear 204. The top of the fixed plate 203 is provided with an annular groove body 215 adapted to the support slide 214. The bottom end of the support slide 214 slides in cooperation with the annular groove body 215. The first ratchet 205 and the second ratchet 206 are both installed at the driving end of the driving motor 301. One of the ratchet ring bodies 208 is fixedly installed On the inner ring surface of the transmission gear 204, another ratchet ring body 208 is fixedly installed at the bottom of the active rod 302. The serrations of the first ratchet 205 and the second ratchet 206 are distributed in opposite directions. The first ratchet 205 is flush with the transmission gear 204, and its outer side is engaged with the corresponding ratchet ring body 208. The outer side of the second ratchet 206 is engaged with another ratchet ring body 208. The matching tooth plate 207 is fixed to the movable end of the extension connecting piece, and one side of it is meshed with the transmission gear 204. The ratchet ring body 208 includes a circular ring and a plurality of arc-shaped spring pieces fixed on the inner ring surface of the circular ring. The number of serrations on the arc-shaped spring pieces is the same as that on the ratchet.

[0052] Please refer to Figure 10 to Figure 11 The extension connection member includes a driving slider 209 and a connecting rod telescopic body 210. A contraction groove body 211 is provided on one side of the sliding base plate 202. One side of the driving slider 209 is slidably connected to one side of the contraction groove body 211. The connecting rod telescopic body 210 is arranged in the contraction groove body 211. One of the connecting rod ends at one end of the connecting rod telescopic body 210 is slidably connected to one side of the contraction groove body 211, and the other connecting rod end is hinged to one side of the driving slider 209, and the two connecting rod ends at the other end of the connecting rod telescopic body 210 are slidably connected to one side of the fixed plate 203. The connecting rod telescopic body 210 is composed of a plurality of groups of cross-hinged rod bodies that are hinged end to end in sequence.

[0053] It should be noted that when the support mechanism 2 is in use, when the rotary drive mechanism 3 drives the support seat 201 to rotate, the driving end of the drive motor 301 is controlled to rotate clockwise, and the first ratchet 205 and the second ratchet 206 are driven at the same time. Since the rotation direction of the driving end is opposite to the direction in which the second ratchet 206 is allowed to rotate, the pawl ring body 208 has a resistance effect on the second ratchet 206, so that the pawl ring body 208 and the active rod 302 rotate together with the second ratchet 206, and the first ratchet 205 is allowed to rotate. The direction is consistent with the rotation direction of the driving end. When the first ratchet 205 rotates, it generates an extrusion force on the arc-shaped spring piece on the pawl ring body 208, causing the arc-shaped spring piece to shrink. Therefore, the pawl ring body 208 will not have a resistance effect on the first ratchet 205. When the first ratchet 205 rotates, the transmission gear 204 will not rotate accordingly. Therefore, at this time, the rotation drive mechanism 3 can only drive the support seat 201 to rotate. When the infrared thermal imaging device needs to be repaired, it can be adjusted to the extended state, and the driving motor 301 can be controlled to drive the drive motor 301. The first end of the second ratchet 206 rotates counterclockwise. At this time, the second ratchet wheel 206 will not drive the corresponding pawl ring 208 to rotate, but the first ratchet wheel 205 will drive the corresponding pawl ring 208 to rotate together, thereby causing the transmission gear 204 to start rotating. Driven by the transmission gear 204, the toothed plate begins to slide linearly along one side of the contraction groove 211, and generates a thrust on the connecting rod 406 at the end of the connecting rod telescopic body 210, thereby causing the entire connecting rod telescopic body 210 to move and extend. Since the fixing plate 203 is fixed to the installation position, When the connecting rod telescopic body 210 is extended, an outward thrust is generated on the sliding base plate 202, and then the sliding base plate 202 slides linearly along the top surface of the fixed plate 203, and the support seat 201, the thermal imager body 1 and the maintenance mechanism 4 slide outward together until the connecting rod telescopic body 210 is extended to the longest state, and the driving motor 301 stops rotating. At this time, the infrared thermal imaging device is in a fully extended state, making it closer to the staff, making it easier for the staff to perform maintenance operations without moving power equipment or the staff entering a narrow space for operation.

[0054] The mounting assembly provided in the present invention has an automatic extension function. By cooperating with the rotating drive mechanism 3 and controlling the rotation direction of the rotating drive mechanism 3, the thermal imager body 1 can be driven to rotate and extend respectively without adding an additional driving source, thereby reducing the actual power consumption of the infrared thermal imaging device and reducing its use cost.

[0055] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
