Description

Technical Field

[0001] This utility model belongs to the field of detection device technology, specifically relating to a detection device that can detect hot spots or microcracks. Background Technology

[0002] Devices for detecting hot spots or microcracks in photovoltaic modules are crucial for the operation and maintenance of photovoltaic power plants and for quality control in module production. Infrared thermal imagers capture the surface temperature distribution of the modules; hot spots generate significant heat due to increased resistance, appearing as high-temperature points in the thermal image.

[0003] A utility model patent with patent authorization announcement number CN218301357U discloses a photovoltaic module hot spot detection device, including a first adjustment mechanism, a second adjustment mechanism, and a detection unit. The first adjustment mechanism includes a first support base, a first guide rail opened on one side wall of the first support base, a first slider slidably disposed in the first guide rail, a first motor disposed on one side wall of the first guide rail, the output end of the first motor being connected to a first screw, and the other end of the first screw passing through the first slider and rotatably connected to the other side wall of the first guide rail. The second adjustment mechanism includes a second support base, one end of which is connected to the first slider. The second adjustment mechanism also includes a second guide rail, a second slider, and a second motor, using the same connection method as the first adjustment mechanism.

[0004] However, existing detection devices for hot spots or microcracks also have certain shortcomings. Although existing detection devices for hot spots or microcracks use infrared detectors to detect hot spots or microcracks in photovoltaic modules, the limited location of the infrared detectors results in poor detection range and efficiency for photovoltaic modules. Summary of the Invention

[0005] The purpose of this invention is to provide a detection device that can detect hot spots or microcracks, which solves the problem that existing detection devices that can detect hot spots or microcracks use infrared detectors to detect hot spots or microcracks in photovoltaic modules, but the limited range and efficiency of the infrared detectors in detecting photovoltaic modules are due to the constraints of the location where the infrared detectors are used.

[0006] To achieve the above objectives, this utility model provides a detection device for detecting hot spots or microcracks, comprising a support shell, a support foot fixedly connected to the lower end of the support shell, a motor fixedly mounted on the front of the support shell, an output shaft of the motor fixedly connected to the support shell, a screw fixedly connected to the output shaft of the motor, the screw being rotatably connected to the support shell, a slider threadedly connected to the outer side of the screw, the slider being slidably connected to the support shell, an oil injection mechanism provided on the slider, a support plate fixedly connected to the right end of the slider, a drive shaft mounted on the inner wall of the support plate via a bearing, a mounting plate fixedly connected to the lower end of the drive shaft, an infrared detector fixedly mounted on the lower end of the mounting plate, a gear fixedly sleeved on the outer side of the drive shaft, and a positioning mechanism jointly provided on the drive shaft and the support plate.

[0007] The principle of this utility model is as follows: the output shaft of motor one is driven to rotate, which in turn drives the screw to rotate. Under the threaded connection, the slider can be driven to slide along the inner wall of the support shell, thereby moving the support plate and then moving the infrared detector head. When the output shaft of motor two drives gear two to rotate, under the meshing relationship, gear one can be driven to rotate, which in turn drives the drive shaft to rotate, thereby driving the infrared detector head to rotate. The position and angle of the infrared detector head can be adjusted to improve the detection range and efficiency of photovoltaic modules.

[0008] When the drive shaft rotates, the pressure from the inner wall of the positioning hole pushes the positioning rod to move, causing the slide plate to slide along the inner wall of the mounting plate, and causing the limit block and limit plate to slide along the surface of the support shell to ensure the stability of the slide plate's movement. This causes the spring to deform, eventually causing the positioning rod to disengage from the positioning hole. Under the action of force, the positioning rod slides along the surface of the drive shaft. When the positioning rod slides into the next positioning hole, the spring returns to its original deformation to push the positioning rod into the positioning hole, thus limiting the drive shaft and preventing the rotational inertia of the drive shaft from causing unnecessary movement of the infrared detector.

[0009] By pulling the end rod upwards, the mounting housing is moved. Under the pressure of the inner wall of the guide hole in the mounting box, the sealing rod can be pushed to slide along the inner wall of the mounting housing, causing the elastic element to deform. Finally, the sealing rod is disengaged from the guide hole. Under the action of the guide tube, the lubricating oil can be guided, so that the lubricating oil comes into contact with the oil suction sleeve, and finally the lubricating oil comes into contact with the screw, thus lubricating the screw and the slider to reduce friction loss and ensure good driving effect of the screw.

[0010] The beneficial effects of this utility model are as follows: This solution, through the setting of the infrared detector head, can be used to detect hot spots, microcracks, etc. in photovoltaic modules. Under the action of the motor and gear, the infrared detector head can be driven to rotate, improving the detection range and efficiency of photovoltaic modules. With the positioning hole, positioning rod, spring and other structures, the drive shaft can be rotated and limited, thereby positioning the infrared detector head. Through the setting of the motor and screw, the slider can be driven to move, thereby displacing the infrared detector head for subsequent detection. Under the movement of the end rod, the desulfurization guide hole of the sealing rod can be opened, and with the action of the guide pipe and oil suction sleeve, the screw can be lubricated to reduce the material wear between the screw and the slider, thereby ensuring a good driving effect of the screw.

[0011] Furthermore, a reinforcing rib is welded to the lower end of the support plate, and the short right-angled side of the reinforcing rib is welded to the slider. By setting the reinforcing rib, the support plate can be reinforced.

[0012] Furthermore, a second motor is fixedly installed on the upper end of the support plate, and a second gear is fixedly sleeved on the outer side of the output shaft of the second motor. The second gear meshes with the first gear, and through the meshing relationship, when the second gear rotates, it can drive the first gear to rotate.

[0013] Furthermore, the oil injection mechanism includes an oil suction sleeve. Both the front and rear ends of the slider are fixedly connected to the oil suction sleeve, which is slidably connected to the screw. An installation box is fixedly connected to the upper end of the slider, and the installation box is slidably connected to the support shell. An end rod is slidably connected to the inner wall of the installation box, and an installation shell is fixedly connected to the surface of the end rod. The installation shell is slidably connected to the installation box. A sealing rod is slidably connected to the inner wall of the installation box, and the sealing rod is slidably connected to the guide hole of the installation box. An elastic element is bonded to the end face of the sealing rod, and the other end of the elastic element is bonded to the installation shell. Through the elastic element and the sealing rod, the guide hole of the installation box can be sealed to ensure the airtightness of the installation box.

[0014] Furthermore, a guide pipe is fixedly connected to the inner wall of the mounting box, and the vertical part of the guide pipe is fixedly connected to the oil suction sleeve. Through the setting of the guide pipe, the lubricating oil can be guided for use.

[0015] Furthermore, the positioning mechanism includes a positioning hole. The surface of the drive shaft has a positioning hole. A slide plate is slidably connected to the inner wall of the support plate. A limit plate is fixedly connected to the upper end of the slide plate. The limit plate is slidably connected to the support plate. Limit blocks are fixedly connected to both the front and rear ends of the slide plate. The limit blocks are slidably connected to the support plate. A spring is welded to the left end of the slide plate. The other end of the spring is welded to the support plate. A positioning rod is fixedly connected to the right end of the slide plate. The positioning rod is slidably connected to the positioning hole. Through the cooperation of the positioning hole and the positioning rod, the drive shaft can be rotated and positioned, thereby positioning the angle of the infrared detector.

[0016] Furthermore, multiple positioning holes are provided, and these multiple positioning holes are arranged in a circular array on the drive shaft. The positioning holes facilitate the engagement with the positioning rod. Attached Figure Description

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, the slider 5 is equipped with an oil injection mechanism 6, which includes an oil suction sleeve 60. The front and rear ends of the slider 5 are fixedly connected to the oil suction sleeve 60, which is slidably connected to the screw 4. The upper end of the slider 5 is fixedly connected to a mounting box 61, which is slidably connected to the support shell 1. A guide pipe 62 is fixedly connected to the inner wall of the mounting box 61, and the vertical part of the guide pipe 62 is fixedly connected to the oil suction sleeve 60. Through the guide pipe 62, lubricating oil can be guided for use. The inner wall of the mounting box 61... An end rod 63 is slidably connected, and a mounting shell 64 is fixedly connected to the surface of the end rod 63. The mounting shell 64 is slidably connected to the mounting box 61. A sealing rod 65 is slidably connected to the inner wall of the mounting box 61. The sealing rod 65 is slidably connected to the guide hole of the mounting box 61. An elastic element 66 is bonded to the end face of the sealing rod 65. The other end of the elastic element 66 is bonded to the mounting shell 64. Through the setting of the elastic element 66 and the sealing rod 65, the guide hole of the mounting box 61 can be sealed to ensure the airtightness of the mounting box 61.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a positioning mechanism 14 is jointly provided on the drive shaft 8 and the support plate 7. The positioning mechanism 14 includes positioning holes 140. Multiple positioning holes 140 are provided on the surface of the drive shaft 8, and the multiple positioning holes 140 are arranged in a circular array on the drive shaft 8. The positioning holes 140 facilitate the engagement with the positioning rod 145. A sliding plate 141 is slidably connected to the inner wall of the support plate 7. A limit plate 142 is fixedly connected to the upper end of the sliding plate 141. The limit plate 142 and the support plate 7 are connected to each other. The sliding connection is provided. Limiting blocks 143 are fixedly connected to both the front and rear ends of the slide plate 141. The limiting blocks 143 are slidably connected to the support plate 7. A spring 144 is welded to the left end of the slide plate 141. The other end of the spring 144 is welded to the support plate 7. A positioning rod 145 is fixedly connected to the right end of the slide plate 141. The positioning rod 145 is slidably connected to the positioning hole 140. Through the cooperation of the positioning hole 140 and the positioning rod 145, the drive shaft 8 can be rotated and positioned, thereby positioning the angle of the infrared detector head 10.

[0029] The specific implementation process of this utility model is as follows: The output shaft of motor 3 is driven to rotate, thereby driving screw 4 to rotate. Under the threaded connection, slider 5 can be driven to slide along the inner wall of support shell 1, thereby driving support plate 7 to move, and then driving infrared detector 10 to move. When motor 212 drives output shaft to drive gear 213 to rotate, under the meshing relationship, gear 11 can be driven to rotate, thereby driving drive shaft 8 to rotate, and then driving infrared detector 10 to rotate. The position, angle, etc. of infrared detector 10 are adjusted to improve the detection range and efficiency of photovoltaic modules.

[0030] When the drive shaft 8 rotates, the positioning rod 145 can be pushed to move under the pressure of the inner wall of the positioning hole 140, so as to drive the slide plate 141 to slide along the inner wall of the mounting plate 9, and drive the limiting block 143 and the limiting plate 142 to slide along the surface of the support shell 1, so as to ensure the stability of the movement of the slide plate 141, causing the spring 144 to deform, and finally causing the positioning rod 145 to disengage from the positioning hole 140. Under the action of force, the positioning rod 145 slides along the surface of the drive shaft 8. When the positioning rod 145 slides into the next positioning hole 140, the spring 144 restores its deformation, so as to push the positioning rod 145 into the positioning hole 140, limit the drive shaft 8, and avoid the problem of unnecessary movement of the infrared detector head 10 caused by the rotational inertia of the drive shaft 8.

[0031] By pulling the end rod 63 upward, the mounting shell 64 is moved. Under the pressure of the inner wall of the guide hole of the mounting box 61, the sealing rod 65 can be pushed to slide along the inner wall of the mounting shell 64, causing the elastic element 66 to deform. Finally, the sealing rod 65 is disengaged from the guide hole. Under the action of the guide tube 62, the lubricating oil can be guided, so that the lubricating oil comes into contact with the oil suction sleeve 60, and finally the lubricating oil comes into contact with the screw 4, so as to lubricate the screw 4 and the slider 5, reduce friction loss, and thus ensure the good driving effect of the screw 4.

[0032] This solution utilizes the infrared detector 10 to detect hot spots and microcracks in photovoltaic modules. The infrared detector 10 is driven to rotate by the motor 12, gear 11, and other components, improving the detection range and efficiency. The positioning hole 140, positioning rod 145, and spring 144 limit the rotation of the drive shaft 8, thus positioning the infrared detector 10. The motor 3, screw 4, and other components drive the slider 5 to move, displacing the infrared detector 10 for subsequent detection. The movement of the end rod 63 opens the desulfurization guide hole of the sealing rod 65. Combined with the guide pipe 62 and oil suction sleeve 60, the screw 4 is lubricated, reducing wear between the screw 4 and slider 5 and ensuring good driving performance of the screw 4.
