Description

Technical Field

[0001] This invention relates to the field of PTZ camera technology, specifically a thermal imaging PTZ camera. Background Technology

[0002] In today's era of rapid technological advancement, the demand for efficient and accurate monitoring equipment is growing in numerous fields such as security monitoring, industrial inspection, and disaster early warning. Thermal imaging PTZ cameras have emerged and play a crucial role in this development. PTZ cameras possess flexible rotation capabilities, allowing for a wide range of horizontal and vertical rotation, greatly expanding the monitoring field of view and enabling comprehensive, blind-spot-free monitoring of target areas. As the monitoring requirements of various industries continue to increase, single-function thermal imaging devices or ordinary PTZ cameras can no longer meet the needs of complex scenarios. The combination of thermal imaging technology and PTZ cameras has led to the creation of the thermal imaging PTZ camera, which retains the advantages of thermal imaging technology... With its precise ability to capture the thermal characteristics of targets and the flexible rotation of the pan-tilt-zoom (PTZ) unit, thermal imaging PTZ cameras can quickly locate and track targets, enabling real-time monitoring of dynamic scenes. In the field of security monitoring, whether it is urban security, border patrol, or perimeter protection of important locations, thermal imaging PTZ cameras can leverage their unique advantages to promptly detect potential threats at night or in adverse weather conditions, ensuring safety. In industrial inspection, they can monitor the operating status of equipment in real time, identifying potential faults in advance through changes in heat distribution, thus preventing equipment damage and production accidents. In disaster early warning, they can quickly detect abnormal heat sources such as fires and leaks, providing strong support for timely response measures.

[0003] Existing thermal imaging PTZ cameras still have some shortcomings. When there are large dust particles or high concentrations of fog in the working environment, traditional equipment lacks an effective active protection and removal mechanism. This causes dust and fog particles to adhere directly to the lens surface, forming a physical shielding layer. This shielding significantly weakens the transmission efficiency of infrared radiation, resulting in blurred thermal images, reduced contrast, and even artifact interference. This seriously affects the thermal imaging camera's ability to accurately capture the temperature distribution of target objects, directly reducing the accuracy and reliability of monitoring data. In addition, regarding dynamic dust removal technology, the dust removal devices in existing equipment are mostly fixed or have a single-direction air outlet structure. They cannot dynamically adjust the airflow direction, intensity, and coverage based on the actual location, distance, and concentration of dust. For close-range dust, traditional dust removal methods can maintain a basic cleaning effect. However, when facing dust clumps at a distance of more than 5 meters, the airflow intensity decreases exponentially due to the airflow diffusion attenuation effect, causing a sharp drop in dust removal efficiency. Especially for dust clumps at a greater distance, traditional dust removal methods are difficult to effectively remove due to the airflow attenuation effect. This leads to frequent fluctuations in image quality when thermal imaging cameras work continuously in harsh environments, affecting the detection results. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal imaging PTZ camera to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thermal imaging PTZ camera, comprising:

[0006] The main fixing plate has a fixed mounting platform on its upper surface, a thermal imaging camera on its upper surface, and an auxiliary testing mechanism on its upper surface.

[0009] Furthermore, one end of the connecting main rod is provided with two connecting support rods, and the ends of the two connecting support rods are provided with elastic protrusions. Both sides of the thermal imaging camera are provided with side connecting grooves that cooperate with the elastic protrusions, and the upper surface of the thermal imaging camera is also provided with a laser detector.

[0010] Furthermore, an internal connecting ring is provided at the end of each of the two connecting rods, and a central collar is fitted on the outer surface of the connecting main rod. Multiple small telescopic motors are provided on the outer surface of the central collar. Each small telescopic motor has a top arc plate at the end of its output shaft. The multiple top arc plates are connected by an elastic connecting section. A connecting shaft seat is provided on the upper surface of each top arc plate. A small connecting rod is provided at the center of the connecting shaft seat. A pressurized jet head is provided at one end of the small connecting rod. A load-bearing ring is provided at one end of the pressurized jet head. A fixed shaft seat is provided on the bottom surface of the pressurized jet head. The bottom surfaces of the multiple fixed shaft seats are all connected to the outer surface of the internal connecting ring.

[0011] Furthermore, a fixing seat is provided on the upper surface of the flip plate, and multiple exhaust fans are provided at the center of the fixing seat. The number of exhaust fans is the same as the number of pressurized jet heads. Each exhaust fan corresponds to one pressurized jet head, and an air supply hose is connected between each corresponding pressurized jet head and the exhaust fan.

[0012] Furthermore, the auxiliary testing mechanism also includes auxiliary components, which include: a fixed base rod, which is disposed on the bottom surface of the central collar; a sliding side post is disposed on both sides of the bottom surface of the fixed base rod; a bottom sliding post is disposed below the fixed base rod; a limiting ring frame is disposed on both sides of the upper end of the bottom sliding post; two sliding side posts are respectively disposed between the two limiting ring frames; a support groove is also provided on the upper surface of the fixed mounting platform; a slidable support slider is disposed inside the support groove; an insertion port for cooperating with the bottom sliding post is provided on the upper surface of the fixed mounting platform; a small groove is also provided on the upper surface of the fixed mounting platform; a small spring rod is disposed inside the small groove; a plug is disposed at one end of the small spring rod; a circular hole is provided on the inner side surface of the small groove to facilitate the insertion and exit of the plug; the circular hole communicates with the support groove; and a circular hole is also provided on the side surface of the support slider that is close to the small spring rod.

[0013] Furthermore, the upper surface of the flip plate is provided with a slidable external protective cover. One end of the external protective cover has multiple air vents. The bottom surface of the external protective cover is provided with an engaging sliding strip located on the bottom surface of the flip plate. The upper surface of the flip plate is provided with a sliding slot to facilitate the connection between the external protective cover and the engaging sliding strip. The bottom surface of the flip plate is provided with a bottom motor, and the output shaft of the bottom motor engages with the center of the engaging sliding strip.

[0014] Furthermore, the bottom surface of the fixed mounting platform is also provided with an adjustment motor, the bottom surface of the adjustment motor is provided with a central fixing column, the bottom surface of the central fixing column is provided with a bottom mounting plate, and both sides of the upper surface of the bottom mounting plate are provided with a limiting base frame that cooperates with the flip plate body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this solution, an air outlet component is installed to achieve efficient and precise air gathering and air jet functions. The starting component uses an electric rotating shaft to drive the flip plate to flip, realizing the dynamic expansion and contraction of the air gathering component. In normal operation, it makes way for the thermal imaging camera without affecting its normal operation. When dust and fog affect the observation, the air gathering component is precisely pushed to the position connected to the thermal imaging camera. In the air gathering component, the small telescopic motor, top arc plate, small connecting rod and other structures work together to adjust the outward expansion and inward contraction of multiple pressurized jet heads according to the position and distance of the dust detected by the laser detector. This precisely controls the jet direction, so that the airflow from multiple pressurized jet heads gathers in the direction of the dust, improving the dust removal effect at a distance. This effectively solves the problem that the thermal imaging camera cannot accurately observe due to dust and fog interference in complex environments, and ensures the stable operation of the thermal imaging camera in various harsh environments.

[0017] 2. In this solution, auxiliary components provide comprehensive support for the normal operation of the air outlet component. The fixed base rod on the bottom of the central collar and its supporting structure effectively bear the weight of the air-gathering component after it is connected to the thermal imaging camera, reducing the burden on the thermal imaging camera during rotation and preventing the excessive weight of the air-gathering component from affecting its angle adjustment. Simultaneously, the innovative combination of the support slider and bottom sliding pile allows the air-gathering component to slide and bear its weight when the thermal imaging camera rotates left and right. When adjusting the angle up and down, the sliding design of the sliding side pile and the limiting ring frame ensures normal adjustment. Furthermore, the external protective cover and engaging sliding strips allow the air-gathering component to retract after the air-gathering component is retracted when a large amount of dust is detected. This creates an air curtain by engaging the pressurized jet nozzle with the air outlet, using a low-power exhaust fan to effectively remove and prevent dust adhesion. This solves the problem of dust around the equipment affecting the thermal imaging camera, comprehensively ensuring the stable operation of the thermal imaging PTZ camera.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1 to 8 A thermal imaging PTZ camera, comprising:

[0029] The main mounting plate 1 serves as the core base of the entire thermal imaging monitoring system. It is made of high-strength aerospace-grade aluminum using a one-piece molding process, ensuring the overall structural stability. A mounting platform 3 is installed on the upper surface of the main mounting plate 1. The mounting platform 3 employs a three-stage shock absorption design, with silicone shock-absorbing pads embedded at the bottom, a honeycomb-shaped aluminum alloy support frame in the middle, and a non-slip carbon fiber plate covering the top, providing an excellent shock-resistant and stable platform for the thermal imaging camera 4. The thermal imaging camera 4 is mounted on the upper surface of the mounting platform 3, secured to it via a quick-release clip structure. Its lens faces the preset observation direction and is equipped with an autofocus module and temperature compensation circuit to maintain image clarity during use. An auxiliary measurement mechanism is also installed on the upper surface of the main mounting plate 1. This mechanism integrates an air outlet component and auxiliary components to ensure and enhance thermal imaging observation capabilities in harsh environments. The air outlet component includes a starting component and a wind-gathering component. The starting component includes a flip plate 2. An electric rotating shaft 13 is provided at the connection between the main fixing plate 1 and the flip plate body 2, located on one side surface of the main fixing plate 1. A top slide 40 is provided on the upper surface of the flip plate body 2, and a limiting fixing plate 45 is provided on the upper surface of the top slide 40. A servo motor 47 is also provided on the upper surface of the top slide 40, and a meshing vertical rod 46 is engaged with the surface of the output shaft of the servo motor 47. A sliding track is provided on the upper surface of the top slide 40 to facilitate the sliding of the meshing vertical rod 46. The main fixing plate 1 and the flip plate body 2... The upper surface of each component is provided with a top sliding groove 44, and the two top sliding grooves 44 are connected. An opening is provided at the center of the limiting fixing plate 45, and a clamping crossbar 48 is provided inside the opening. One end of the clamping crossbar 48 is connected to the upper side surface of the meshing vertical bar 46. Two clamping connecting plates 49 are provided at the end of the clamping crossbar 48 away from the meshing vertical bar 46, thus forming an end effector that can grasp, push and release. A miniature electric shaft is provided at the connection between the clamping connecting plate 49 and the clamping crossbar 48.

[0030] The starting component drives the flip plate 2 to rotate around the main fixed plate 1 via the electric rotating shaft 13, realizing the dynamic unfolding and storage of the air-gathering component. In normal operation, the air-gathering component is located on the upper surface of the flip plate 2, which is arranged at a 90-degree angle to the main fixed plate 1. The bottom surface of the flip plate 2 is in contact with one side surface of the limiting base 6, thus making way for the thermal imaging camera 4 to perform its daily work. During use, the thermal imaging camera 4 observes the outside. When the thermal imaging camera 4 detects dust or fog that causes a decrease in image quality and makes it unable to make accurate observations, the laser detector 42 on the upper surface of the thermal imaging camera 4 receives a control signal from the small controller inside the thermal imaging camera 4 and starts to emit a laser to determine the location of the dust. Then, the small controller drives the electric rotating shaft 13 to rotate the flip plate 2 90 degrees, making it parallel to the main fixed plate 1. Subsequently, the servo motor 47 receives the control signal... After the start of the drive, the output shaft engages with the vertical rod 46, pushing the air-gathering component toward the thermal imaging camera 4. The connection is completed when one side of the vertical rod 46 contacts the side of the limiting plate 45. Then, the two clamping connecting plates 49 at the end of the clamping crossbar 48 flip outwards under the action of the micro-electric shaft, causing them to lose their clamping effect on the air-gathering component. Subsequently, the servo motor 47 reverses its drive, resetting the vertical rod 46 and the clamping crossbar 48 to make room for the air-gathering component. After the air-gathering component finishes its work, the servo motor 47 restarts, bringing the clamping crossbar 48 closer to the air-gathering component and re-clamping it through the two clamping connecting plates 49. The servo motor 47 then reverses its drive again, pulling the air-gathering component back to its original position via the clamping crossbar 48. Finally, the electric rotating shaft 13 starts, causing the flipping plate 2 to flip downwards and reset.

[0031] The air-gathering component achieves airflow directional control through a modular mechanical structure. The air-gathering component includes: a clamping protrusion 36, which is positioned between two clamping connecting plates 49. The upper and lower surfaces of the clamping protrusion 36 are provided with fixing slots 37. The adjacent surfaces of the two clamping connecting plates 49 are each provided with a locking protrusion that mates with the fixing slots 37. The clamping protrusion 36 is made of high-strength aluminum alloy, and its fixing slots 37 on its upper and lower surfaces are trapezoidal, forming a self-locking engagement with the locking protrusions on the inner sides of the clamping connecting plates 49. One end of the clamping protrusion 36 is provided with an end limiting plate 34. One side of the end limiting plate 34... The thermal imaging camera 4 has a locking protrusion 35 on one side surface, and a locking interface that mates with the locking protrusion 35 on one side surface. The end limiting plate 34 has a connecting main rod 33 on the side surface opposite to the clamping protrusion 36. Two connecting support rods 38 are provided at one end of the connecting main rod 33, and elastic protrusions 32 are provided at the ends of the two connecting support rods 38. Side connecting grooves 43 that mate with the elastic protrusions 32 are provided on both sides of the thermal imaging camera 4. The elastic protrusions 32 are covered with wear-resistant rubber, enabling quick engagement and disengagement with the side connecting grooves 43 on both sides of the thermal imaging camera 4. The upper surface of the thermal imaging camera 4 also has... A laser detector 42 is provided. An internal connecting ring 20 is located at the end of each of the two connecting rods 38. A central collar 25 is fitted onto the outer surface of the main connecting rod 33. Multiple small telescopic motors 26 are mounted on the outer surface of the central collar 25. Each small telescopic motor 26 has a top arc plate 23 at the end of its output shaft. The multiple top arc plates 23 are connected by elastic connecting sections 24. A connecting shaft seat 22 is located on the upper surface of each top arc plate 23. A small connecting rod 21 is located at the center of the connecting shaft seat 22. A pressurized jet head 15 is located at one end of the small connecting rod 21. One end is provided with a load-bearing ring 16, which is made of lead alloy material and is used to lower the center of gravity of the system and enhance wind resistance stability. The bottom surface of the pressurized jet head 15 is provided with a fixed shaft seat 31, and the bottom surface of multiple fixed shaft seats 31 is connected to the outer surface of the internal connecting ring 20. The upper surface of the flip plate body 2 is also provided with a fixed seat 18, and multiple exhaust fans 19 are provided at the center of the fixed seat 18. The number of exhaust fans 19 is the same as the number of pressurized jet heads 15. Each exhaust fan 19 corresponds to one pressurized jet head 15, and each corresponding pressurized jet head 15 and exhaust fan 19 are connected by an air supply hose 17.

[0032] When the existing thermal imaging camera 4 is observing, if there is a lot of dust in the environment, the detection accuracy will decrease to a certain extent due to the scattering, absorption, or blocking of infrared radiation by the dust. The air-gathering component realizes intelligent dynamic removal of interference. The air-gathering component is used when the thermal imaging camera 4 cannot make accurate observations due to the presence of a lot of dust and fog in the working environment. When the starting component drives the flip plate 2 to rotate 90 degrees to keep it parallel to the main fixing plate 1, the air-gathering component can be activated. After the clamping crossbar 48 pushes the air-gathering component to the target position of the thermal imaging camera 4, the two elastic protrusions 32 at the ends of the two connecting rods 38 engage with the side connecting grooves 43. Then, the clamping crossbar 48 is flipped by the two clamping connecting plates 49, losing the connection effect with the air-gathering component. At this time, when the thermal imaging camera 4 is rotating and adjusting its angle normally, the air-gathering component can move synchronously with it, so that it can always act on the observation direction of the thermal imaging camera 4. After the air-gathering component is connected to the fixed mounting platform 3, the fixed base Multiple exhaust fans 19 at the center of the 18th position are activated to draw in air from the outside and transmit it through the air delivery hose 17 to the interior of the pressurized jet head 15. The air is then discharged from the outlet of the pressurized jet head 15. At this time, the small signal processor inside the central fixed column 7 drives the small telescopic motor 26 to extend synchronously based on the distance between the dust position detected by the laser detector 42 and the thermal imaging camera 4. When the small telescopic motor 26 extends, it will fix the top arc plate 23 at its end outward and cause the small connecting rod 21 to rotate along the axis connected to the connecting shaft seat 22, and cause the pressurized jet head 15 to rotate along the axis connected to the fixed shaft seat 31. This synchronously adjusts the outward and inward expansion and contraction of the pressurized jet head 15, thereby adjusting the jet direction of each pressurized jet head 15. By adjusting the length of the small telescopic motor 26, the airflow emitted by multiple pressurized jet heads 15 can be concentrated in the direction of the dust, thereby improving the dust removal effect at a distance and ensuring that the observation work of the thermal imaging camera 4 is not affected.

[0033] The auxiliary components are key modules for ensuring stable system operation and functional expansion. These components include: a fixed base rod 27, which is located on the bottom surface of the central collar 25; a sliding side post 28 on each side of the bottom surface of the fixed base rod 27; a bottom sliding post 30 below the fixed base rod 27; and a limiting ring frame 29 on each side of the upper end of the bottom sliding post 30. The two sliding side posts 28 are nested within their respective limiting ring frames 29, forming a sliding structure that allows relative vertical sliding to accommodate the pitch of the thermal imaging camera 4. As the angle changes, the upper surface of the fixed mounting platform 3 is also provided with a support groove 41. A slidable support slider 50 is installed inside the support groove 41. The upper surface of the support slider 50 has an insertion port that mates with the bottom sliding post 30. The upper surface of the fixed mounting platform 3 is also provided with a small groove. A small spring rod 39 is installed inside the small groove. A stopper is provided at one end of the small spring rod 39. A circular hole is provided on the inner side surface of the small groove to facilitate the insertion and removal of the stopper. Under the action of the spring, the stopper at the end of the small spring rod 39 can pass through the circular hole on the side wall of the platform. In its natural state, the slider is inserted into the corresponding hole on the side of the support slider 50, locking it in the initial position of the slide groove. The circular hole communicates with the support slide groove 41. A circular hole is also provided on the side surface of the support slider 50 that is close to the small spring rod 39. A slidable outer protective cover 9 is also provided on the upper surface of the flip plate 2. Multiple air vents 10 are provided at one end of the outer protective cover 9. An engaging sliding strip 12 is provided on the bottom surface of the outer protective cover 9. The engaging sliding strip 12 is located on the bottom surface of the flip plate 2. The upper surface of the flip plate 2 is provided with a feature that facilitates the engagement and sliding of the outer protective cover 9. The sliding slot 14 is connected to the strip 12. The bottom surface of the flip plate 2 is provided with a bottom motor 11. The output shaft of the bottom motor 11 meshes with the center of the meshing sliding strip 12, which can precisely drive the outer protective cover 9 to slide back and forth. The bottom surface of the fixed mounting platform 3 is also provided with an adjustment motor 5. The bottom surface of the adjustment motor 5 is provided with a central fixing column 7. The bottom surface of the central fixing column 7 is provided with a bottom mounting plate 8. Both sides of the upper surface of the bottom mounting plate 8 are provided with a limiting base frame 6 that cooperates with the flip plate 2, which is used to stably support and limit the flip plate 2 when it is stored.

[0034] The auxiliary components provide stability support and extended protection for the entire system. During use, because the air-gathering component is connected to the fixed mounting platform 3, the rotation range of the thermal imaging camera 4 is limited by the air delivery hose 17, allowing it to rotate only 90 degrees to the left and right. To compensate for the limited observation range of the thermal imaging camera 4, after observing one side, to ensure observation of the area behind the equipment, the adjustment motor 5 on its bottom drives the main fixing plate 1 and the flip plate 2 to rotate 180 degrees. When the horizontal rotation range of the camera is limited due to the connection of the air-gathering component, the adjustment motor 5 drives the main fixing plate 1 to rotate 180 degrees, thereby switching the observation field of view to the rear of the equipment and achieving panoramic coverage compensation. Furthermore, after the air-gathering component is connected to the thermal imaging camera 4, to prevent the angle adjustment of the thermal imaging camera 4 from being affected by the excessive weight of the air-gathering component, the weight is supported by the fixed base rod 27 on the bottom surface of the central collar 25, thereby reducing the weight that the thermal imaging camera 4 needs to bear when rotating. When the air-gathering component is not connected to the fixed mounting platform 3, the small spring rod 39 inside the small groove drives the plug to pass through the two circular holes and insert into the inside of the support slider 50 through its internal spring, thereby fixing the position of the support slider 50. When the air-gathering component moves to connect with the fixed mounting platform 3, the bottom sliding post 30 on its bottom surface also slides inside the top sliding groove 44 as the air-gathering component moves, and finally inserts into the support slider 50. Inside block 50, the plug is pushed out from inside the support slider 50. At this time, when the thermal imaging camera 4 rotates left and right, the bottom sliding post 30 slides and follows the support slider 50 inside the support groove 41. The support slider 50 bears the weight of the wind-gathering component. When the thermal imaging camera 4 is adjusted up and down, the two sliding side posts 28 at the end of the fixed bottom rod 27 slide inside the two limiting ring frames 29. This ensures that the weight of the wind-gathering component can be reduced when the thermal imaging camera 4 is adjusted at a normal angle. In addition, the auxiliary component integrates an adaptive air curtain protection function. When the flip plate 2 is flipped and parallel to the main fixed plate 1, the outer protective cover 9 on the surface of the flip plate 2 also moves synchronously with the flip plate 2. Under normal conditions, the engaging sliding strip 12 on the bottom surface of the outer protective cover 9 remains at the position furthest from the main fixed plate 1 inside the sliding slot 14, thus preventing any impact on the normal operation of the thermal imaging camera 4 and the air outlet assembly. When the fixed mounting platform 3 detects a significant amount of dust in the environment surrounding the equipment, after the air-gathering component has finished its use, it is driven to retract and reset via the starting component, thus disconnecting the air-gathering component from the thermal imaging camera 4. At this time, the air-gathering component completely retracts into the outer protective cover 9. Meanwhile, the electric rotating shaft 13 does not drive the flip plate 2 to flip and reset, keeping the flip plate 2 parallel to the main fixed plate 1. Multiple small telescopic motors 26 are driven by a small controller inside the fixed mounting platform 3 to retract synchronously.Multiple pressurized jet nozzles 15 are synchronously expanded outwards, and the air outlets of the multiple pressurized jet nozzles 15 engage with multiple air outlets 10 on the surface of the outer protective cover 9. At this time, the exhaust fan 19 starts at low power, and the airflow forms an annular air curtain around the key parts of the equipment (especially the mirror surface of the thermal imaging camera 4) through the docked pressurized jet nozzles 15 and air outlets 10. This effectively blocks and blows away nearby floating dust, realizing the equipment's active self-cleaning and local environmental maintenance. The bottom motor 11 is started, which allows the outer protective cover 9 to slide inside the sliding slot 14, enabling it to cover the thermal imaging camera 4. This provides a certain degree of protection for the thermal imaging camera 4 in the event of strong light or rain in the working environment.

[0035] The working principle of this invention is:

[0036] The main fixing plate 1 serves as the core base, and a fixing mounting platform 3 is set on its upper surface. It adopts a three-level shock absorption design to provide a stable platform for the thermal imaging camera 4. The thermal imaging camera 4 is fixed to the fixing mounting platform 3 through a quick-release buckle structure. The lens faces the preset direction and is equipped with an autofocus module and a temperature compensation circuit to ensure clear imaging.

[0037] When the thermal imaging camera 4 detects dust or fog that causes a decrease in image quality, the laser detector 42 on its upper surface receives a signal from the miniature controller and is activated. It emits a laser to determine the location of the dust. Subsequently, the miniature controller drives the electric rotating shaft 13 to rotate, rotating the flipping plate 2 to a state parallel to the main fixing plate 1. At this time, the servo motor 47 in the starting component is driven and, through the engagement of the output shaft with the meshing vertical rod 46, pushes the air-gathering component to move toward the thermal imaging camera 4. When the meshing vertical rod 46 contacts the limiting fixing plate 45, it stops, and the air-gathering component completes the connection with the thermal imaging camera 4. Then, the two clamping connecting plates 49 at the end of the clamping crossbar 48 are flipped outward under the action of the miniature electric shaft, losing the clamping effect on the air-gathering component. The servo motor 47 is driven in reverse, driving the meshing vertical rod 46 and the clamping crossbar 48 to reset, making room for the air-gathering component to work.

[0038] In the air-gathering component, the elastic protrusions 32 at the ends of the two connecting rods 38 engage with the side connecting slots 43 on both sides of the thermal imaging camera 4. At this time, the exhaust fan 19 on the fixed base 18 starts, draws air from the outside and transmits it to the pressurized jet head 15 through the air supply hose 17. The airflow is ejected from the air outlet. The small signal processor inside the central fixed column 7 drives the small telescopic motor 26 to extend synchronously according to the dust position and distance detected by the laser detector 42, adjusts the position of the top arc plate 23, makes the pressurized jet head 15 rotate, changes the jet direction, and makes the airflow ejected by multiple pressurized jet heads 15 gather in the direction of dust, thus improving the cleaning effect.

[0039] The auxiliary components provide stability support and extended protection. When the air-gathering component connection restricts the rotation range of the thermal imaging camera 4, the adjustment motor 5 drives the main fixing plate 1 to rotate 180 degrees to achieve panoramic coverage compensation. The fixed bottom rod 27 on the bottom surface of the central collar 25 reduces the weight borne by the thermal imaging camera 4 when it rotates. When the thermal imaging camera 4 rotates left and right, the bottom sliding pile 30 slides and follows the support slider 50 in the support sliding groove 41. When adjusting up and down, the sliding side pile 28 at the end of the fixed bottom rod 27 slides in the limiting ring frame 29. In addition, when there is a lot of dust around the equipment, the air-gathering component retracts into the outer protective cover 9, the small telescopic motor 26 retracts, the air outlet of the pressurized jet head 15 engages with the air outlet 10, and the exhaust fan 19 starts at low power to form an annular air curtain to block and blow away dust. In strong light or rain, the bottom motor 11 drives the outer protective cover 9 to slide and cover the thermal imaging camera 4, which plays a protective role.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
