[0050] In this embodiment, the preset thermal performance analysis algorithm adopts a dynamic thermal balance model; the data analysis unit performs anomaly detection on the data, and when abnormal fluctuations are detected in the data of the heat flow meter 4, temperature and humidity sensor and infrared thermal imaging camera 6, an alarm signal is issued. Specifically, the alarm information is remotely pushed to the monitoring terminal by using a buzzer and LED flashing.
[0051] In this embodiment, the control device includes a remote monitoring terminal. A waterproof wireless transmission module sends the data processed by the central processing module and the operating status information of the control device to the remote monitoring terminal. The remote monitoring terminal can display various data and operating status of the device in real time, and can also send remote control commands to the central processing module to realize remote monitoring and control of the control device.
[0052] Specifically, the terminal integrated data visualization includes heat flux density distribution thermograms, internal and external surface temperature and humidity curves, and equipment status.
[0053] In this embodiment, solar panels are symmetrically arranged on both sides of the main frame beam 20, and a storage battery is installed inside the fixing block 9. The storage battery is electrically connected to the input terminal of the motor 34 and the motor input terminal of the fan 10 through cables.
[0054] Specifically, flexible monocrystalline silicon photovoltaic panels (thickness ≤ 2mm, weight ≤ 3kg / m²) are used to fit the two sides of the main frame beam 20, converting light energy into electrical energy and reducing external dependence.
[0055] To achieve the above effect, a frame 2 is set up, which includes a main frame beam 20. The lower end of the main frame beam 20 is fixedly connected to the upper end of the base frame 1. The beam array of the main frame beam 20 is provided with an auxiliary frame 21. The beam of the main frame beam 20 is provided with mounting holes 22 that are adapted to the auxiliary frame 21.
[0056] Specifically, the main frame beam 20 is made of high-strength aluminum alloy profile with an I-shaped cross section. The spacing between adjacent auxiliary frames 21 is 900mm. Each auxiliary frame 21 is an L-shaped bracket, and its vertical section is fixed to the side of the main frame beam 20 by welding. The auxiliary frame 21 is quickly positioned by positioning pins and mounting holes 22, and is connected by bolts to support the on-site disassembly and maintenance of components such as heat flow meter 4 and adjustment mechanism 3.
[0057] In this embodiment, the adjustment mechanism 3 includes a heat dissipation window 31. A rotating rod 33 is fixedly connected to one side of the heat dissipation window 31. Bearings 32 are rotatably connected to both ends of the rotating rod 33. The outer ring of the bearing 32 is fixedly connected to the inner wall of the mounting hole 22. A motor 34 is embedded in the block of the fixing block 9. The output shaft of the motor 34 is rotatably connected to the beam of the main frame beam 20 through the bearing. A helical gear 35 is fixedly connected to the output shaft of the motor 34. A rotating gimbal 36 is provided at the upper end of the helical gear 35. The rotating part of the rotating gimbal 36 is connected to the infrared thermal imaging camera. The lower end of the head 6 is fixedly connected. The surface of the helical gear 35 is meshed with the second helical gear 37. A first spur gear is provided on one side of the second helical gear 37. One side of the first spur gear is rotatably connected to the beam of the main frame beam 20 through a bearing. The surface of the first spur gear is meshed with a set of spur gears 38. The set of spur gears 38 is a combination of two spur gears. One of the spur gears in the set of spur gears 38 meshes with the surface of the first spur gear. The other spur gear in the set of spur gears 38 meshes with a toothed belt 39. One side of the set of spur gears 38 is fixedly connected to the inner ring of the bearing 32.
[0058] Specifically, when the angle of the heat dissipation window 31 needs to be adjusted, the motor 34 starts, and the output shaft of the motor 34 rotates, driving the helical gear 35, which is fixedly connected to it, to rotate. Since the helical gear 35 meshes with the second helical gear 37, the rotation of the helical gear 35 drives the second helical gear 37 to rotate. The first spur gear, which is set on one side of the second helical gear 37, rotates accordingly. The rotation of the first spur gear transmits power to the spur gear set 38 through meshing with it. The spur gear set 38 consists of two interconnected spur gears, one meshing with the first spur gear and the other meshing with the toothed belt 39. When the spur gear set 38 rotates, the meshing with the toothed belt 39 produces a linear transmission effect. Because one side of the spur gear set 38 is fixedly connected to the inner ring of the bearing 32, and the outer ring of the bearing 32 is fixedly connected to the inner wall of the mounting hole 22, the heat dissipation window... The rotating rod 33, fixedly connected to one side of 31, is rotatably connected to the bearings 32 at both ends. Therefore, the linear transmission of the toothed belt 39 will cause the rotating rod 33 to rotate under the support of the bearings 32, thereby adjusting the angle of the heat dissipation window 31. At the same time, the rotation of the output shaft of the motor 34 will also drive the rotating part of the rotating gimbal 36 to rotate. Since the rotating part of the rotating gimbal 36 is fixedly connected to the lower end of the infrared thermal imaging camera 6, the infrared thermal imaging camera 6 will rotate with the rotating gimbal 36 to adjust its shooting angle, which is convenient for thermal imaging monitoring of different positions. The output shaft of the motor 34 is rotatably connected to the beam of the main frame beam 20 through the bearings, which ensures the stability of the motor 34 during rotation and reduces the generation of vibration and noise. Furthermore, due to the presence of the rotating gimbal 36, the infrared thermal imaging camera 6 can be rotated and adjusted a second time.
[0059] In this embodiment, the edge of the waterproof membrane 5 is provided with a flow guide groove, the opening of the flow guide groove faces the outside of the frame 2, the waterproof membrane 5 is made of polytetrafluoroethylene coated material, and a detachable dust cover is provided at the lens of the infrared thermal imaging camera 6.
[0060] Specifically, the drainage channels on the edge of the waterproof membrane 5 play an important role in drainage. When it rains, rainwater falling on the waterproof membrane 5 will flow along its surface to the drainage channels on the edge. Since the opening of the drainage channels faces the outside of the frame 2, the rainwater will be guided to the outside of the frame 2 and discharged, preventing rainwater from accumulating on the waterproof membrane 5 and thus preventing rainwater from penetrating into the frame 2 and damaging the equipment. The waterproof membrane 5 is made of polytetrafluoroethylene (PTFE) coating material. PTFE has good waterproof, corrosion resistance, and weather resistance. This material can effectively block the erosion of rainwater and resist the damage of chemicals and ultraviolet rays in the external environment, extending the service life of the waterproof membrane 5 and ensuring its long-term stable waterproof performance. The removable dust cover on the lens of the infrared thermal imaging camera 6 can effectively prevent dust and debris from adhering to the lens during daily use. Dust and debris will affect the imaging quality of the infrared thermal imaging camera 6, causing blurry images or interference. When a lot of dust accumulates on the dust cover, staff can easily remove it for cleaning or replacement, thus ensuring that the infrared thermal imaging camera 6 can always perform clear and accurate thermal imaging monitoring.
[0061] 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.
