Description

Technical Field

[0001] The present invention relates to the technical field of detection and alarm technology, and in particular to a detection and early warning device for a photovoltaic power generation panel. Background Art

[0002] Photovoltaic panels are devices that use the photovoltaic effect to convert sunlight directly into electricity. Because panels receive sunlight for extended periods of time, their surface temperature must be monitored, as temperature has a direct impact on their power generation efficiency. Real-time monitoring of the surface and ambient temperature of PV panels allows for assessment of their power generation efficiency and heat loss, which is crucial for the operation, maintenance, and optimization of PV power plants. Regular detection of leakage anomalies on the panel surface is also essential.

[0003] In the existing technology, when detecting temperature and current anomalies on the surface of photovoltaic panels, it is necessary to directly install and fix the temperature sensor and current detection probe on the surface of the photovoltaic panel. Therefore, the monitoring sensor will also be exposed to sunlight for a long time, which will lead to a high failure rate. In addition, the temperature detection range of a single temperature sensing module is limited, and it is impossible to flexibly detect the temperature at different positions on the surface of the photovoltaic panel or even the bottom area.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] See also Figures 1 to 8 The present invention provides the following technical solutions: a detection and early warning device for photovoltaic panels, comprising a detection and early warning device body and a photovoltaic panel 1, wherein the detection and early warning device body comprises a detection board 2, a driving mechanism 3, a detection component 4 and a leakage detection mechanism 5, wherein the detection board 2 is welded to the end of the photovoltaic panel 1, the driving mechanism 3 is screwed to one end of the detection board 2, a plurality of leakage detection mechanisms 5 are embedded on the surface of the detection board 2, a screw rod 8 is inserted in the driving mechanism 3, the detection component 4 is sleeved on the surface of the screw rod 8, and the detection component 4 is disposed on the surface of the screw rod 8. The device comprises a lifting mechanism 13 and a fitting mechanism 14. The bottom of the lifting mechanism 13 is provided with a threaded sleeve 16, through which the screw rod 8 passes. The top of the lifting mechanism 13 is integrally formed with a back plate 21. One end of the fitting mechanism 14 rests against the inner side of the back plate 21. The fitting mechanism 14 is used to press against the surface of the detection plate 2 or rest against the bottom of the detection plate 2. The bottom of the fitting mechanism 14 is integrally formed with a plug-in piece 30, which is used to pass through the interior of the leakage detection mechanism 5. This photovoltaic panel detection and warning device is used to detect abnormal surface and bottom temperature of photovoltaic panels, as well as whether there is abnormal leakage in the photovoltaic panels.

[0030] When the present invention is installed, the detection plate 2 and the photovoltaic panel to be tested are welded as a whole, and the driving mechanism 3 on the detection plate 2 is used to drive the screw rod 8 to rotate, and the screw rod 8 cooperates with the lifting mechanism 13 to drive the top fitting mechanism 14 to move. When the fitting mechanism 14 moves to the front end of the detection plate 2, it can be supported by the support plate 10 and the inclined plate 11, so that the top area of the detection component 4 moves to the top of the detection plate 2. Therefore, when the detection component 4 is subsequently controlled by the motor 6 to move toward the rear end, it can ensure that the fitting mechanism 14 is on the surface of the detection plate 2 and moves. During this movement process, the temperature of multiple areas on the surface of the photovoltaic panel can be measured with the help of the temperature monitoring module 27, and it can also cooperate with multiple leakage detection mechanisms 5 to detect the leakage status of different areas on the surface of the photovoltaic panel. When it moves to the end of the detection plate 2, the detection component 4 can be automatically controlled to move down to the bottom of the detection plate 2. When the detection component 4 is subsequently pulled forward by the motor 6, the temperature of the bottom area of the detection plate 2 can be detected again.

[0031] In this embodiment, a front end plate 7 and a rear end plate 36 are welded to the two ends of the detection plate 2, and a lifting notch 12 and a lowering notch 35 are provided on the surface of the detection plate 2. A motor 6 is screwed to the outer side of the front end plate 7, and a guide rod 9 is welded between the front end plate 7 and the rear end plate 36. A support plate 10 is integrally formed on the inner wall of the front end plate 7, and an inclined plate 11 is provided at the end of the support plate 10. The lifting notch 12 and the lowering notch 35 have the same size specifications, the guide rod 9 and the screw rod 8 are parallel to each other, and the end of the screw rod 8 is embedded in the inner wall of the rear end plate 36 through a bearing. The surface of the support plate 10 is parallel to the surface of the detection plate 2, and the outer ends of the lifting notch 12 and the lowering notch 35 are both open, and the lifting notch 12 is above the support plate 10. Notch structures are provided at the front and rear ends of the detection board 2. In conjunction with the lifting mechanism 13 in the detection component 4, the lifting and switching process can be automatically completed when the entire detection component 4 moves to the front and rear ends. With the help of this switching structure, it is ensured that the detection component 4 can be quickly and safely lowered completely to the bottom of the detection board 2 at the descending notch 35. At the same time, it can also ensure that the thermal conductive plate 26 can be completely and tightly fitted with the bottom of the detection board 2 when the temperature of the bottom surface of the photovoltaic panel 1 is detected, thereby improving the efficiency and accuracy of temperature detection.

[0032] Specifically, when the detection assembly 4 is at the bottom of the detection plate 2 in the initial state, the motor 6 is started, and the screw rod 8 is rotated in conjunction with the threaded sleeve 16 to pull the lifting mechanism 13 forward until it is pulled to the position of the inclined plate 11. At this time, the first roller 20 under the bottom plate 19 can be pressed on the inclined plate 11 and continue to move along the inclined plate 11, so that the entire bottom plate 19 can be directly pushed upward, and the back plate 21, the top plate 22, the spring rod 23 and the entire bonding mechanism 14 can be driven to move upward at the same time. After the top plate 22 and the bonding plate 24 are moved to the position of the lifting notch 12, the top bonding plate 24 can be continued to move upward under the action of the spring rod 23, and finally the bonding plate 24 is pushed upward from the lifting notch. Since the top plate 22 is always on the outside of the detection plate 2, it will not block the bonding plate 24. Finally, after the bonding plate 24 is moved to the surface of the detection plate 2.

[0033] In this embodiment, the lifting mechanism 13 includes a back plate 21 and a lifting sleeve 15. The top of the back plate 21 is integrally formed with a top plate 22, and the bottom of the back plate 21 is integrally formed with a bottom plate 19. A first roller 20 is inserted into the bottom of the bottom plate 19. A lifting plate 18 is welded to one end of the bottom of the bottom plate 19. The bottom end of the lifting plate 18 is embedded in the interior of the lifting sleeve 15. The bottom end of the lifting sleeve 15 is integrally formed with a threaded sleeve 16 and a guide sleeve 17. The guide rod 9 passes through the interior of the guide sleeve 17. The first roller 20 is used to press against the surface of the support plate 10. The detection assembly 4 is controlled to reciprocate by the driving mechanism 3. The notches at the front and rear ends can automatically position the detection assembly 4 at the top and bottom positions of the photovoltaic panel 1 when moving forward and backward. Therefore, when not performing detection, the detection assembly 4 can be partially hidden with the help of this structure, reducing the probability of damage to the detection sensor due to direct sunlight.

[0034] Specifically, when the fitting mechanism 14 is moving above the detection plate 2, the motor 6 is started to move the entire detection component 4 along the surface of the detection plate 2, so as to achieve the purpose of subsequent detection of the temperature and leakage abnormality on the surface of the detection plate 2, until the detection component 4 is moved to the descending notch 35 at the rear end. At this time, the fitting mechanism 14 loses the support of the detection plate 2 and the support of the bottom support plate 10. Therefore, the lifting plate 18 will be embedded in the interior of the lifting sleeve 15 and will drop to the bottom position of the detection plate 2 again. At this position, the detection component 4 is moved forward by the driving mechanism 3, so that the temperature monitoring module 27, the electrode column 29, the electrode sheet 31 and the wire part connected to the electrode in the detection component 4 can be hidden to avoid long-term high-temperature exposure and achieve the protection effect of part of the detection component 4.

[0035] In this embodiment, the bonding mechanism 14 includes a bonding plate 24 and a spring rod 23. An electrode column 29 is inserted into the bottom of the bonding plate 24, and a plug-in plate 30 is welded to the bottom of the electrode column 29. An electrode sheet 31 is embedded on the surface of the plug-in plate 30. The spring rod 23 is inserted into the surface of the bonding plate 24. The top of the spring rod 23 is welded to the bottom of the top plate 22, and the bottom of the spring rod 23 is welded to the surface of the bottom plate 19. A second roller 28 is inserted into the bottom end of the bonding plate 24, and the second roller 28 is used to press on the surface of the detection plate 2. An extension column 39 is also inserted into the surface of the bonding plate 24. The two ends of the extension column 39 are integrally formed with a heat conducting plate 26. The surface of the extension column 39 is integrally formed with a fixing ring 38. The side of the fixing ring 38 is integrally formed with a heat conducting plate 37. The end of the heat conducting plate 37 is mounted with a temperature monitoring module 27. The leakage detection mechanism 5 includes a baffle 32 and a conductive plate 34. The conductive plate 34 is embedded in the interior of the photovoltaic panel 1. The inner side of the baffle 32 is provided with a plug-in slot 33. The plug-in plate 30 passes through the interior of the plug-in slot 33. The electrode sheet 31 is fitted with the inner wall of the baffle 32. The conductive plate 34 is partially electrically connected to the electrode sheet 31 through the baffle 32. A fitting mechanism 14 is installed on the surface of the detection component 4, and a heat-conducting structure is passed through the edge of the fitting mechanism 14. Therefore, based on the above-mentioned movement of the detection component 4 at the top and bottom of the detection plate 2, the front and back of the entire photovoltaic panel 1 can be provided with temperature detection effects, so that more comprehensive surface temperature data of the photovoltaic panel 1 can be obtained by only using a single temperature monitoring device.

[0036] Specifically, when the bonding mechanism 14 moves along the surface of the detection plate 2, the heat conducting plate 37 at the bottom of the extension column 39 is partially pressed on the surface of the detection plate 2. Therefore, during the movement of the entire bonding mechanism 14, heat can be transferred through the heat conducting plate 26, the extension column 39, and the heat conducting plate 37, and finally the temperature monitoring module 27 is used to achieve the purpose of temperature detection of multiple areas on the surface of the detection plate 2. At the same time, through the movement of the bonding mechanism 14, the bottom plug-in piece 30 is partially embedded in the plug-in slot 33 of the baffle 32, and the electrode piece 31 is bonded to the inner wall of the baffle 32, and finally the conductive plate 34 is cooperated to detect and process the leakage state of the surface of the photovoltaic panel. When the entire detection component 4 is under the detection plate 2, as the driving mechanism 3 pulls the detection component 4, the detection component 4 will eventually be pulled onto the support plate 10. At this time, the bottom plate 19 can be lifted upward with the help of the support plate 10, and the bonding mechanism 14 rises synchronously, and finally the bonding plate 24 is pressed against the bottom of the detection plate 2. At this time, the conductive sheet part at the top of the extension column 39 can be pressed against the bottom of the detection plate 2, and finally the temperature monitoring purpose of the bottom of the detection plate 2 is achieved at this position.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
