Description

TECHNICAL FIELD

[0001] The present application relates to photovoltaic power station equipment monitoring technical field, specifically to a kind of photovoltaic power station equipment energy efficiency dynamic monitoring device. BACKGROUND

[0002] Photovoltaic power station equipment is the equipment using the photovoltaic effect of semiconductor interface and converts light energy into electrical energy directly, in order to dynamically monitor the energy efficiency of photovoltaic power station equipment, infrared thermal imager is usually used.

[0003] The existing infrared thermal imager dynamic monitoring device needs to be exposed to the outside for a long time, so dust will inevitably adhere to the lens, which will cause lens pollution and affect the scanning accuracy, thus misjudgment problems are prone to occur.

[0004] Therefore, the existing infrared thermal imager monitoring device can be self-cleaning, that is, the driving shaft of the motor is used to drive the wiping member to wipe the infrared thermal imager lens, so as to achieve the purpose of cleaning the lens and ensure the scanning accuracy. However, since the driving shaft of the motor drives the wiping member to make circular motion, the lens outside the circular arc cannot be wiped. If the length of the scraping strip is set too long, the above problem can be solved, but the scraping strip is prone to breakage due to wind.

[0005] Therefore, we design a kind of photovoltaic power station equipment energy efficiency dynamic monitoring device to solve the above problems. SUMMARY

[0008] Furthermore, a mounting groove is provided on one side of the first scraper, and one end of the second scraper is slidably inserted into the mounting groove. The end of the reset spring away from the second scraper is fixedly installed on the inner side wall of the mounting groove.

[0009] Furthermore, a telescopic rod is fixedly installed between the inner sidewall of the mounting groove and the second scraper, and the reset spring is movably sleeved on the telescopic rod.

[0010] Furthermore, the first cleaning component is slidably connected in the sliding groove, and two supporting springs are fixedly installed between the first cleaning component and the top wall of the sliding groove. An iron block is provided on the top of the first cleaning component, and an electromagnet is fixedly installed on the top wall of the sliding groove. The magnetic field polarity of the electromagnet is the same as that of the iron block.

[0011] Furthermore, the drive assembly includes a mounting plate, which is fixedly mounted on the front end of the top of the infrared thermal imager. Both the front side of the infrared thermal imager and the front side of the mounting plate are rotatably provided with rotating shafts. The connector is fixedly sleeved on one of the rotating shafts. A transmission roller is fixedly sleeved on the rotating shaft. A belt is tensioned and sleeved on both transmission rollers. A motor is fixedly mounted on the rear side of the mounting plate. The drive shaft of the motor is connected to one end of one of the rotating shafts.

[0012] Furthermore, an adjusting shaft is rotatably provided on the bottom wall of the opening, and a fixing groove is provided on one side of the fixing frame. A motor is fixedly installed in the fixing groove, and the drive shaft of the motor is connected to one end of the adjusting shaft.

[0013] Furthermore, two mounting seats are symmetrically arranged on the top of the support plate, and a drive shaft is arranged between the two mounting seats. The infrared thermal imager is rotatably sleeved on the drive shaft. A gap is left between the support plate and the infrared thermal imager, and an electric push rod is rotatably arranged between them.

[0014] Furthermore, a fixed base is fixedly installed on the top of the support plate, a limiting base is fixedly installed on the bottom of the infrared thermal imager, and the two ends of the electric push rod are respectively rotatably disposed in the fixed base and the limiting base.

[0015] Furthermore, a first pin is provided inside the fixed seat, a second pin is provided inside the limiting seat, and the two ends of the electric push rod are respectively rotatably sleeved on the first pin and the second pin.

[0016] Furthermore, the front side of the infrared thermal imager is provided with a first permanent magnet block and a second permanent magnet block, and the top and bottom of the first scraper are respectively provided with a first iron sheet and a second iron sheet.

When the first scraper rotates back, the iron piece and the permanent magnet strip lose their magnetic attraction, and the return spring can pull the second scraper into the mounting groove, avoiding the problem of the cleaning structure breaking due to wind force due to excessive length.

[0018] Compared with the prior art, the beneficial effects of the present invention are: when the second scraper slides out of the first scraper, the electromagnet can be turned on. Since the magnetic field polarity of the electromagnet is the same as that of the iron block, the electromagnet can generate a repulsive force on the iron block and push the first cleaning component downward until the first cleaning component is flush with the second cleaning component. This can facilitate the guidance of the scraped dust and avoid the problem of dust accumulation.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: by turning on the motor, the drive shaft of the motor can drive the adjustment shaft and the infrared thermal imager to rotate 180°. Then, when the infrared thermal imager rotates to the point where the second iron sheet and the second permanent magnet block are in contact, the dust will slide out of the fixed frame along the second cleaning part and the first cleaning part. This not only makes it convenient to clean the scraped dust, but also prevents the dust from falling on the photovoltaic panel and prevents the dust from adhering to the lens of the infrared thermal imager a second time.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Please see Figures 1-7This invention provides a technical solution: a dynamic energy efficiency monitoring device for photovoltaic power station equipment, comprising a photovoltaic panel 1, a fixing frame 2 fixedly installed on one side of the top of the photovoltaic panel 1, an opening 3 opened in the fixing frame 2, a support plate 4 disposed in the opening 3, an infrared thermal imager 5 disposed on the top of the support plate 4, the infrared thermal imager 5 facing the photovoltaic panel 1, a connector 6 rotatably disposed on one side of the infrared thermal imager 5, a first scraper 7 fixedly installed at one end of the connector 6, a second scraper 8 slidably inserted into one side of the first scraper 7, and a sliding opening at the bottom of the second scraper 8. The first cleaning component 10 is provided in the groove 9 and the bottom of the first scraper 7 is provided with the second cleaning component 11. One end of the first cleaning component 10 is fixedly installed with an iron plate 12, which abuts against one end of the second scraper 8. The first scraper 7 is also provided with a return spring 13, and the other end of the return spring 13 is fixedly connected to the second scraper 8. A permanent magnet strip 14 is fixedly installed on the bottom of one side of the infrared thermal imager 5. The permanent magnet strip 14 is magnetically connected to the iron plate 12. The infrared thermal imager 5 is also provided with a drive assembly for driving the connecting component 6 to rotate. The drive assembly includes a mounting plate 20, which is fixedly mounted on the front end of the top of the infrared thermal imager 5. Rotating shafts 21 are rotatably mounted on both the front side of the infrared thermal imager 5 and the front side of the mounting plate 20. A connector 6 is fixedly sleeved on one of the rotating shafts 21. A transmission roller 22 is fixedly sleeved on the rotating shaft 21, and a belt 23 is tensioned and sleeved on both transmission rollers 22. A motor 24 is fixedly mounted on the rear side of the mounting plate 20, and the drive shaft of the motor 24 is connected to one end of one of the rotating shafts 21. Two mounting seats 28 are symmetrically arranged on the top of the support plate 4. A drive shaft 29 is provided between the support plate 4 and the infrared thermal imager 5, which is rotatably sleeved on the drive shaft 29. A gap is left between the support plate 4 and the infrared thermal imager 5, and an electric push rod 32 is rotatably provided. A fixed seat 30 is fixedly installed on the top of the support plate 4, and a limit seat 31 is fixedly installed on the bottom of the infrared thermal imager 5. The two ends of the electric push rod 32 are respectively rotatably set in the fixed seat 30 and the limit seat 31.

[0026] In practice, by turning on the infrared thermal imager 5 and in conjunction with turning on the electric push rod 32, the drive end of the electric push rod 32 can extend and retract, causing the infrared thermal imager 5 to rotate upward or downward around the transmission shaft 29 as the axis. This allows for adjustment of the optimal angle of the lens on the infrared thermal imager 5 towards the photovoltaic panel 1, thus facilitating the monitoring of the photovoltaic panel 1. When an excessive temperature difference is detected in a certain area of ​​the photovoltaic panel 1, it indicates that there is an abnormal fault in the photovoltaic panel 1, which will affect the working energy efficiency. Subsequently, the electrical signal is remotely sent to the management terminal, realizing the effect of real-time monitoring of the energy efficiency of the photovoltaic panel 1. After prolonged use, the lens of the infrared thermal imager 5 will inevitably accumulate a lot of dust. At this time, the motor 24 is turned on, causing one of the rotating shafts 21 and the transmission roller 22 to rotate. This causes the belt 23 to move, driving the other rotating shaft 21 and the transmission roller 22 to rotate. During this process, the connecting piece 6 will drive the first scraper 7 to rotate clockwise, allowing the second cleaning piece 11 to scrape off the dust on one side of the lens surface of the infrared thermal imager 5. When the first scraper 7 moves above the permanent magnet strip 14, the iron piece 12 will be attracted to the permanent magnet strip 14, and will cause the first cleaning piece 10 and the second scraper 8 to stretch the return spring 13 and slide out of the mounting groove 15. This increases the overall length of the cleaning structure, allowing for thorough cleaning of the lens. When the first scraper 7 rotates back, the iron piece 12 and the permanent magnet strip 14 lose their magnetic attraction, allowing the return spring 13 to pull the second scraper 8 into the mounting groove 15 due to its own tension, thus preventing the cleaning structure from breaking due to wind exposure because it is too long.

[0027] See Figures 1-7 The first scraper 7 has a mounting groove 15 on one side, and one end of the second scraper 8 is slidably inserted into the mounting groove 15. The end of the return spring 13 away from the second scraper 8 is fixedly installed on the inner side wall of the mounting groove 15. This facilitates the sliding installation of the second scraper 8 into the first scraper 7 and avoids motion interference.

[0028] See Figures 1-7 A telescopic rod 16 is also fixedly installed between the inner wall of the mounting groove 15 and the second scraper 8, and a return spring 13 is movably sleeved on the telescopic rod 16. This allows the second scraper 8 to slide only along the telescopic end of the telescopic rod 16, avoiding the problem of movement deviation.

[0029] See Figures 1-7 The first cleaning component 10 is slidably connected in the sliding groove 9. Two support springs 17 are fixedly installed between the first cleaning component 10 and the top wall of the sliding groove 9. An iron block 19 is provided on the top of the first cleaning component 10. An electromagnet 18 is fixedly installed on the top wall of the sliding groove 9. The magnetic field polarity of the electromagnet 18 is the same as that of the iron block 19.

[0030] In specific implementation, based on the above implementation, when the second scraper 8 slides out of the first scraper 7, the electromagnet 18 can be turned on. Since the magnetic field polarity of the electromagnet 18 is the same as that of the iron block 19, the electromagnet 18 can generate a repulsive force on the iron block 19 and push the first cleaning component 10 downward until the first cleaning component 10 is flush with the second cleaning component 11. This can facilitate the guidance of the scraped dust and avoid the problem of dust accumulation.

[0031] See Figures 1-7An adjusting shaft 25 is rotatably installed on the bottom wall of the opening 3. A fixing groove 26 is provided on one side of the fixing frame 2. A motor 27 is fixedly installed in the fixing groove 26. The drive shaft of the motor 27 is connected to one end of the adjusting shaft 25.

[0032] In specific implementation, based on the above implementation, before cleaning the dust, by turning on the motor 27, the drive shaft of the motor 27 can drive the adjustment shaft 25 and the infrared thermal imager 5 to rotate 180°. Then, when the infrared thermal imager 5 rotates to the point where the second iron sheet and the second permanent magnet block 34 are in contact, the dust will slide out of the fixing frame 2 along the second cleaning part 11 and the first cleaning part 10. This not only makes it convenient to clean the scraped dust, but also prevents the dust from falling on the photovoltaic panel 1 and prevents the dust from adhering to the lens of the infrared thermal imager 5 again.

[0033] See Figures 1-7 The front side of the infrared thermal imager 5 is provided with a first permanent magnet block 33 and a second permanent magnet block 34. The top and bottom of the first scraper 7 are respectively provided with a first iron sheet and a second iron sheet. The first permanent magnet block 33 is magnetically connected to the first iron sheet, and the second permanent magnet block 34 is magnetically connected to the second iron sheet.

[0034] In specific implementation, based on the above implementation, before cleaning the dust, by turning on the motor 27, the drive shaft of the motor 27 can drive the adjustment shaft 25 and the infrared thermal imager 5 to rotate 180°. Then, when the infrared thermal imager 5 rotates to the point where the second iron sheet and the second permanent magnet block 34 are in contact, the dust will slide out of the fixing frame 2 along the second cleaning part 11 and the first cleaning part 10. This not only makes it convenient to clean the scraped dust, but also prevents the dust from falling on the photovoltaic panel 1 and prevents the dust from adhering to the lens of the infrared thermal imager 5 again. By setting the first permanent magnet block 33 to magnetically attract the first iron sheet, the first scraper 7 can be limited to avoid the first scraper 7 affecting the operation of the infrared thermal imager 5.

[0035] Working principle: Before use, all electrical appliances on the mounting bracket 2 need to be connected to an external power source, or a battery pack needs to be installed on the mounting bracket 2 in an area that does not obstruct other components. Then, the battery pack is connected to the electrical appliance through a line to supply power to the appliance, thereby ensuring its normal operation. It should be noted that since connecting the electrical appliance to an external power source or setting up a battery pack for power supply is existing technology and is not a problem that needs to be solved in the background technology of this manual, it will not be explained in detail.

[0036] In use, by turning on the infrared thermal imager 5 and simultaneously turning on the electric push rod 32, the drive end of the electric push rod 32 can extend and retract, causing the infrared thermal imager 5 to rotate upward or downward around the transmission shaft 29 as the axis. This allows for adjustment of the optimal angle of the lens on the infrared thermal imager 5 towards the photovoltaic panel 1, facilitating the monitoring of the photovoltaic panel 1. When an excessive temperature difference is detected in a certain area of ​​the photovoltaic panel 1, it indicates that there is an abnormal fault in the photovoltaic panel 1, which will affect the working energy efficiency. Subsequently, the electrical signal is remotely sent to the management terminal, realizing the effect of real-time monitoring of the energy efficiency of the photovoltaic panel 1.

[0037] After prolonged use, the lens of the infrared thermal imager 5 will inevitably accumulate a lot of dust. At this time, the motor 24 is turned on, causing one of the rotating shafts 21 and the transmission roller 22 to rotate. This causes the belt 23 to move, driving the other rotating shaft 21 and the transmission roller 22 to rotate. During this process, the connecting piece 6 will drive the first scraper 7 to rotate clockwise, allowing the second cleaning piece 11 to scrape off the dust on one side of the lens surface of the infrared thermal imager 5. When the first scraper 7 moves above the permanent magnet strip 14, the iron piece 12 will be attracted to the permanent magnet strip 14, and will cause the first cleaning piece 10 and the second scraper 8 to stretch the return spring 13 and slide out of the mounting groove 15. This increases the overall length of the cleaning structure, allowing for thorough cleaning of the lens. When the first scraper 7 rotates back, the iron piece 12 and the permanent magnet strip 14 lose their magnetic attraction, allowing the return spring 13 to pull the second scraper 8 into the mounting groove 15 due to its own tension, thus preventing the cleaning structure from breaking due to wind exposure because it is too long.

[0038] When the second scraper 8 slides out of the first scraper 7, the electromagnet 18 can be activated. Since the magnetic field polarity of the electromagnet 18 is the same as that of the iron block 19, the electromagnet 18 can generate a repulsive force on the iron block 19 and push the first cleaning component 10 downward until the first cleaning component 10 is flush with the second cleaning component 11. This can facilitate the guidance of the scraped dust and avoid the problem of dust accumulation.

[0039] In addition, before cleaning the dust, by turning on the motor 27, the drive shaft of the motor 27 can drive the adjustment shaft 25 and the infrared thermal imager 5 to rotate 180°. Then, when the infrared thermal imager 5 rotates to the point where the second iron sheet and the second permanent magnet block 34 are in contact, the dust will slide out of the fixing frame 2 along the second cleaning part 11 and the first cleaning part 10. This not only makes it convenient to clean the scraped dust, but also prevents the dust from falling on the photovoltaic panel 1 and prevents the dust from adhering to the lens of the infrared thermal imager 5 again.
