A light pollution regulating device for photovoltaic generator sets

Abstract

The present invention discloses a light pollution control device for a photovoltaic power generation set, which relates to the technical field of photovoltaic power generation sets and includes a control device body provided with a light-transmitting plate. A light-transmitting groove is formed at the upper end of the control device body. Two groups of light-transmitting plates are provided and are rotatably arranged at both ends of the light-transmitting groove. Each group of light-transmitting plates is adapted to the light-transmitting groove. The light-transmitting plates are hingedly arranged by an inner plate and an outer plate. The end of the inner plate away from the outer plate is rotatably connected to the end face of the light-transmitting groove via a rotating shaft. The two groups of light-transmitting plates are arranged to rotate alternately. A bracket is provided inside the control device body directly below the rotating shaft. The present invention switches between the two groups of light-transmitting plates, allowing one group of light-transmitting plates to be cleaned while the other group is in use, thereby avoiding interference with the light transmittance of the light-transmitting plates during the cleaning process. When light is irradiated into the control device body, the reflection of light by the internal reflective element increases the temperature inside the control device body, thereby achieving a drying effect on the light-transmitting plates.

Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation sets, in particular to a light pollution regulating device for a photovoltaic power generation set. Background Art

[0002] Solar energy is a renewable energy source, generated by the enormous nuclear energy released by hydrogen-helium fusion within the sun. The vast majority of energy needed by humans comes directly or indirectly from the sun's radiation energy. Plants release oxygen and absorb carbon dioxide through photosynthesis, converting solar energy into chemical energy and storing it in their bodies. Fossil fuels such as coal, oil, and natural gas are also primary energy sources formed through the evolution of ancient plants and animals buried underground over long geological periods. As fossil fuels become increasingly scarce, solar energy has become an important component of human energy and continues to develop. Solar energy can be utilized through photothermal conversion and photovoltaic conversion. Solar power generation is an emerging renewable energy source.

[0003] For example, a light pollution regulating device for a photovoltaic power generation group as disclosed in "CN114448346A" relates to the technical field of photovoltaic power generation devices, and includes a mounting base, an regulating cavity, and a light collecting portion. The regulating cavity is fixedly mounted on one side of the mounting base, and a light collecting portion is provided on one side of the regulating cavity. A light-transmitting member is installed inside the regulating cavity, and the light-transmitting member has an inclined structure, and one side is mounted relative to the inner wall of the regulating cavity. A first regulating portion is fixedly installed inside the regulating cavity. In the above scheme, the lifting member moves to one side of the sliding column through the compression member, and abuts against the sliding column, driving the interior of the sliding column to slide while driving the photovoltaic panel to change position, thereby reducing the water temperature and affecting the photosynthesis of phytoplankton in the water, thereby increasing the concentration of dissolved oxygen in the water body. This scheme does not require the design of a large-scale base frame to affect the environment in the water body, thereby increasing the diversity of the ecological environment in the water body and ensuring the normal natural development of the ecological environment in the water body.

[0004] However, in the prior art, as shown in the above-mentioned patent, sunlight passes through the uppermost light-receiving plate into the interior, and the uppermost light-receiving plate is usually required to have high strength and good light transmittance. In order to ensure the transmittance, the outer surface of the light-receiving plate needs to be cleaned frequently to ensure that the surface is clean and tidy to avoid obstructing the entry of light. Manual cleaning is usually used for cleaning. If the device is set on water, it will not only increase the difficulty of cleaning, but also be dangerous to clean on water. Alternatively, a self-cleaning device may be set outside the device to self-clean the outer surface of the light-receiving plate. However, when it is set outside, it is easy to be exposed to wind and sun, which greatly reduces the service life of the self-cleaning device. In addition, for example, a cleaning brush is set outside. During the washing process, the surface of the light-receiving plate is blocked, and the light-receiving effect is poor. After water cleaning, there is a certain amount of water stains on the surface of the light-receiving plate. In this state, it is easier to be contaminated with dust, making the cleaning effect not very good. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that the cleaning effect of the top light receiving plate is not very good.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a light pollution regulating device for a photovoltaic power generation group, which includes a regulating device body provided with a light-transmitting plate, a light-transmitting groove being opened at the upper end of the regulating device body, two groups of light-transmitting plates being provided and rotatably arranged at both ends of the light-transmitting groove, each group of light-transmitting plates being adapted to the light-transmitting groove, the light-transmitting plates being hingedly arranged by an inner plate and an outer plate, the end of the inner plate away from the outer plate being rotatably connected to the end face of the light-transmitting groove through a rotating shaft, the two groups of light-transmitting plates being staggered and rotatably arranged, a bracket being provided inside the regulating device body just below the rotating shaft, The inner wall of the adjusting device body at both ends of the bracket is symmetrically provided with slide rails, and a cleaning rack is provided in the bracket. The two ends of the cleaning rack are slidably arranged with the slide rails, and the cleaning rack is slidably sleeved on the outside of the light-transmitting plate. A cleaning roller is rotatably provided at the lower inner side of the cleaning rack and a scraper is slidably provided at the upper end. A dust suction groove connected to the outside is provided inside the adjusting device body at one end of the light-transmitting groove, and a spiral blower is provided inside the upper end of the adjusting device body. The dust suction groove is connected to the air inlet end of the spiral blower, and the air outlet end is connected to the outside of the adjusting device body.

[0009] Furthermore, the air inlet end of the spiral blower is provided with a fixed cover, the outer wall of the fixed cover is assembled and connected to the inner wall of the regulating device body, the dust suction groove is connected to the fixed cover through an upper pipe, and a water storage tank is provided at one end below the fixed cover away from the spiral blower, and a water filter pad is provided above the water storage tank. The fixed cover is used to transfer the collected impurities in the fixed cover, and in rainy weather, rainwater can be directly drained into the water storage tank to avoid accumulation and damage to the spiral blower.

[0010] Furthermore, the height of one end of the fixed cover away from the spiral blower is lower than that of the other end, and a rain shield is provided on the inner wall of the fixed cover located at the lower end of the dust suction groove, and the rain shield is arranged at a position facing the spiral blower. The provided rain shield can effectively prevent rainwater from entering the fixed cover from the dust suction groove and dripping to cause a large amount of splashing. The rainwater is buffered by the rain shield and reduces the falling speed, and can drip on the inner wall of the fixed cover as smoothly as possible, thereby effectively avoiding the possibility of rainwater entering the spiral blower. In rainy weather, the spiral blower is not started, and large particles of impurities remain above the water filter pad, and relatively clean rainwater is discharged. In non-rainy weather, when there is no water in the fixed cover, the spiral blower can be started to clean the impurities inside the fixed cover and on the surface of the light-transmitting plate and discharge them to the outside of the regulating device body, and the impurities accumulated on the water filter pad can also be cleaned up.

[0011] Furthermore, a water filter rack is provided on the outside of the regulating device body, a water filter layer is provided in the water filter rack, the lower end of the water storage tank is connected to the top of the water filter rack through a first pipe, the water outlet end of the water filter rack is connected to a water storage cylinder, the output end of the water storage cylinder is connected to the inside of the cleaning rack through a second pipe, and the rainwater after the preliminary filtration can be filtered again through the set water filter rack, and finally discharged into the cleaning rack for cleaning the light-transmitting plate. The water storage cylinder can be used to store more rainwater in rainy weather for use in long-term weather without rain. The specific water storage tank can be transported to the water tank through the pump body.

[0012] Furthermore, a water tank is provided above the interior of the bracket, and a rubber pad is provided above the water tank. The center position of the rubber pad is used to pass the cleaning rack. The two brackets are connected above by a connecting pipe, and the connecting pipe is provided with an overflow pipe connected to the outside. A grid is provided below the interior of the bracket, and a sewage pipe connected to the outside is provided on the end face of the bracket. Water is fed into the water tank through a second pipe. When feeding water, the sewage pipe can be opened first, and dirt is deposited under the grid, which can separate the dirt from the cleaning rack. When water is added, the dirt can be flushed out from the sewage pipe. After the sewage is discharged, the sewage pipe is closed, and water is continued to be fed into the water tank until the overflow pipe overflows. The cleaning rack that is not in use passes through the rubber pad and is stored in the water tank. The rubber pad can prevent the cleaning rack from being directly exposed to sunlight, which may cause the cleaning rack to dry out and be damaged.

[0013] Furthermore, the cleaning frame is arranged in a square structure, and assembly grooves are symmetrically provided on the upper sides of the inside of the cleaning frame. The two scrapers are respectively slidably arranged in the corresponding assembly grooves. A driving mechanism is provided inside the cleaning frame, and the scraper is driven to slide by the driving mechanism. The scraper can be adjusted and retracted in the assembly groove, which facilitates the switching between the cleaning roller and the scraper.

[0014] Furthermore, the driving mechanism includes a first motor, a tooth plate and a long gear. There are two tooth plates, which are respectively arranged on the end faces of the two scrapers and facing each other. The two tooth plates are horizontally offset up and down. The long gear is rotatably arranged at the center position of the end face of the cleaning frame. The long gear is meshed and arranged between the two tooth plates. The long gear is driven to rotate by the first motor, and the long gear is driven to rotate by the first motor, thereby driving the two tooth plates to move in opposite directions synchronously, thereby realizing the synchronous reverse movement of the two scrapers and achieving the synchronous contraction or extension effect.

[0015] Furthermore, sliders are symmetrically provided at both ends of the cleaning rack, the sliders are engaged with the slide rails and are slidably arranged, a first cylinder is provided in the slide rails, and the sliders are driven to slide by the first cylinder.

[0016] Furthermore, the outer plate and the inner plate are driven to rotate by a second motor, and the end face of the rotating shaft is driven to rotate by a third motor. The outer plate and the inner plate are folded by driving the second motor first, and then the inner plate is rotated to the inside of the adjustment device body.

[0017] Furthermore, support plates are symmetrically rotatably provided on both sides of the inner wall of the adjustment device body below the light-transmitting groove. The inner wall of the adjustment device body is rotatably connected to the bottom of the support plate through a second cylinder. In the unfolded state, the top of the support plate is flush with the bottom of the light-transmitting plate. The support plates are provided to support the light-transmitting plate during use to ensure its stability.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention switches between two sets of light-transmitting plates, so that one set of light-transmitting plates can be cleaned while the other set is in use, thereby avoiding interference with the light transmittance of the light-transmitting plates during the cleaning process. When light is irradiated into the interior of the regulating device body, the reflection of the light by the internal reflective element can increase the temperature inside the regulating device body, thereby achieving a drying effect on the light-transmitting plates.

[0020] 2. The present invention can filter the rainwater after preliminary filtration again by setting up a water filter rack, and finally discharge it into the cleaning rack for cleaning the light-transmitting plate. The water storage cylinder can be used to store more rainwater in rainy weather for use in long-term rainless weather. The specific water storage tank can be transported to the water tank through the pump body.

[0021] 3. The present invention allows water to flow into the water tank through a second pipe. When water is introduced, the sewage pipe can be opened first, and dirt is deposited under the grid, which can separate the dirt from the cleaning rack. When water is added, the dirt can be flushed out from the sewage pipe. After the sewage is discharged, the sewage pipe is closed, and water is continued to flow into the water tank until the overflow pipe overflows. When the cleaning rack is not in use, it is stored in the water tank through the rubber pad. The rubber pad can prevent the cleaning rack from being directly exposed to sunlight, which may cause the cleaning rack to dry out and be damaged.

[0022] 4. The rain shield provided in the present invention can effectively prevent rainwater from entering the fixed cover from the dust suction groove and dripping to cause a large amount of splashing. The rainwater is buffered by the rain shield to reduce the falling speed and can drip on the inner wall of the fixed cover as smoothly as possible, thereby effectively avoiding the possibility of rainwater entering the spiral blower. In rainy weather, the spiral blower will not be started, large particles of impurities will remain above the water filter pad, and relatively clean rainwater will be discharged. In non-rainy weather, when there is no water in the fixed cover, the spiral blower can be started to clean the impurities inside the fixed cover and on the surface of the light-transmitting plate and discharge them to the outside of the regulating device body, and the impurities accumulated on the water filter pad can also be cleaned up.

[0038] See also Figures 1-9The present invention provides a technical solution: a light pollution regulating device for a photovoltaic power generation group, comprising a regulating device body 2 provided with a light-transmitting plate 1, a light-transmitting groove 3 being opened at the upper end of the regulating device body 2, two groups of light-transmitting plates 1 being respectively rotatably arranged at both ends of the light-transmitting groove 3, each group of light-transmitting plates 1 being adapted to the light-transmitting groove 3, the light-transmitting plates 1 being hingedly arranged by an inner plate 411 and an outer plate 412, the end of the inner plate 411 away from the outer plate 412 being rotatably connected to the end face of the light-transmitting groove 3 by a rotating shaft 413, the two groups of light-transmitting plates 1 being staggered and rotatably arranged, a bracket 511 being provided inside the regulating device body 2 just below the rotating shaft 413, and the two ends of the bracket 511 being respectively rotatably arranged at both ends of the light-transmitting groove 3 The inner wall of the adjusting device body 2 at the end is symmetrically provided with slide rails 512, and a cleaning frame 513 is provided in the bracket 511. The two ends of the cleaning frame 513 are slidably set with the slide rails 512, and the cleaning frame 513 is slidably sleeved on the outside of the light-transmitting plate 1. A cleaning roller 514 is rotatably provided at the lower inner side of the cleaning frame 513 and a scraper 515 is slidably provided at the upper end. A dust suction groove 516 connected to the outside is provided inside the adjusting device body 2 at one end of the light-transmitting groove 3, and a spiral blower 517 is provided inside the upper end of the adjusting device body 2. The dust suction groove 516 is connected to the air inlet end of the spiral blower 517, and the air outlet end is connected to the outside of the adjusting device body 2.

[0039] like Figures 1-9 As shown, a fixed cover 611 is provided at the air inlet end of the spiral blower 517, and the outer wall of the fixed cover 611 is assembled and connected to the inner wall of the regulating device body 2. The dust suction groove 516 is connected to the fixed cover 611 through the upper tube 612. A water storage tank 613 is provided at the end below the fixed cover 611 away from the spiral blower 517, and a water filter pad 614 is provided above the water storage tank 613. The fixed cover 611 is provided to transfer the collected impurities in the fixed cover 611, and in rainy weather, the rainwater can be directly drained into the water storage tank 613 to avoid accumulation and damage to the spiral blower 517.

[0040] like Figures 1-9 As shown, the height of one end of the fixed cover 611 away from the spiral blower 517 is lower than that of the other end. A rain shield 615 is provided on the inner wall of the fixed cover 611 at the lower end of the dust suction groove 516. The rain shield 615 is provided on the side facing the spiral blower 517. The rain shield 615 can effectively prevent rainwater from entering the fixed cover 611 from the dust suction groove 516 and then dripping to cause a large amount of splashing. The rainwater is buffered by the rain shield 615 and the falling speed is reduced, so that it can drip onto the fixed cover as smoothly as possible. On the inner wall of the fixed cover 611, the possibility of rainwater entering the spiral blower 517 can be effectively avoided. In rainy weather, the spiral blower 517 will not be started, and large particles of impurities will remain on the water filter pad 614, and the relatively clean rainwater will be discharged. In non-rainy weather, when there is no water in the fixed cover 611, the spiral blower 517 can be started to clean the impurities inside the fixed cover 611 and on the surface of the light-transmitting plate 1 and discharge them to the outside of the regulating device body 2, and the impurities accumulated on the water filter pad 614 can also be cleaned away.

[0041] like Figures 1-9 As shown, a water filter rack 711 is provided on the outside of the regulating device body 2, and a water filter layer 712 is provided in the water filter rack 711. The lower end of the water storage tank 613 is connected to the top of the water filter rack 711 through a first pipe 713, and the water outlet end of the water filter rack 711 is connected to a water storage cylinder 714. The output end of the water storage cylinder 714 is connected to the inside of the cleaning rack 513 through a second pipe 715. Through the provided water filter rack 711, the rainwater after the preliminary filtration can be filtered again and finally discharged into the cleaning rack 513 for cleaning the light-transmitting plate 1. The water storage cylinder 714 can be used to store more rainwater in rainy weather for use in long-term rainless weather. The specific water storage tank 613 can be transported to the water tank 811 through the pump body.

[0042] like Figures 1-9 As shown, a water tank 811 is provided above the interior of the bracket 511, and a rubber pad 812 is provided above the water tank 811. The center of the rubber pad 812 is used to pass through the cleaning rack 513. The two brackets 511 are connected to each other through a connecting pipe 813. The connecting pipe 813 is provided with an overflow pipe 814 connected to the outside. A grid 815 is provided below the interior of the bracket 511. A sewage pipe 816 connected to the outside is provided on the end face of the bracket 511. Water is fed into the water tank 811 through the second pipe 715. When the water is discharged, the sewage pipe 816 can be opened first, and the dirt is deposited under the grid 815, which can separate the dirt from the cleaning rack 513. When water is added, the dirt can be flushed out from the sewage pipe 816. After the sewage is discharged, the sewage pipe 816 is closed and water is continued to be supplied to the water tank 811 until the overflow pipe 814 overflows. When the cleaning rack 513 is not in use, it passes through the rubber pad 812 and enters the water tank 811 for storage. The rubber pad 812 can prevent the cleaning rack 513 from being directly exposed to sunlight, which may cause the cleaning rack 513 to dry out and be damaged.

[0043] like Figures 1-9 As shown, the cleaning frame 513 is arranged in a square structure, and assembly grooves 9 are symmetrically provided on the upper sides of the cleaning frame 513. Two scrapers 515 are respectively slidably arranged in the corresponding assembly grooves 9. A driving mechanism is provided inside the cleaning frame 513, and the scraper 515 is driven to slide by the driving mechanism. The scraper 515 can be adjusted and retracted in the assembly groove 9, which facilitates the switching of the cleaning roller 514 and the scraper 515.

[0044] like Figures 1-9As shown, the driving mechanism includes a first motor 101, a tooth plate 102 and a long gear 103. There are two tooth plates 102, which are respectively arranged on the end faces of the two scrapers 515 and facing each other. The two tooth plates 102 are horizontally staggered up and down, and the long gear 103 is rotatably arranged at the center position of the end face of the cleaning frame 513. The long gear 103 is meshed and arranged between the two tooth plates 102. The long gear 103 is driven to rotate by the first motor 101. By driving the first motor 101, the long gear 103 is driven to rotate, and then the two tooth plates 102 are driven to move in opposite directions synchronously, thereby realizing the synchronous reverse movement of the two scrapers 515 and realizing the synchronous contraction or extension effect.

[0045] like Figures 1-9 As shown, sliders 111 are symmetrically provided at both ends of the cleaning frame 513 , and the sliders 111 are engaged with and slidably arranged on the slide rails 512 . A first cylinder 112 is provided in the slide rails 512 , and the sliders 111 are driven to slide by the first cylinder 112 .

[0046] like Figures 1-9 As shown, the outer plate 412 and the inner plate 411 are driven to rotate by the second motor 121, and the end face of the rotating shaft 413 is driven to rotate by the third motor 122. The outer plate 412 and the inner plate 411 are folded by driving the second motor 121 first, and then the inner plate 411 is rotated to the inside of the adjustment device body 2.

[0047] like Figures 1-9 As shown, support plates 132 are symmetrically rotated on both sides of the inner wall of the adjusting device body 2 below the light-transmitting groove 3. The inner wall of the adjusting device body 2 is rotatably connected to the lower part of the support plate 132 through the second cylinder 131. In the unfolded state, the upper part of the support plate 132 is flush with the lower part of the light-transmitting plate 1. The support plate 132 is provided to support the light-transmitting plate 1 during use to ensure its stability.

[0048] Working principle: When cleaning the light-transmitting plate 1 of the regulating device body 2, first drive the spiral blower 517 to discharge the dust, leaves and other impurities on the outer surface of the light-transmitting plate 1 through the dust suction groove 516 and the spiral blower 517 to the outside of the regulating device body 2, so as to achieve preliminary cleaning of the surface of the light-transmitting plate 1, and prevent the particle impurities on the surface of the light-transmitting plate 1 from falling into the inside of the regulating device body 2 when the light-transmitting plate 1 is folded. After the preliminary cleaning, drive and rotate one group of light-transmitting plates 1 to rotate and fold the outer plate 412 toward the inner plate 411, and then rotate the folded inner plate 411 around the rotating shaft 413 to the inside of the regulating device body 2. The folded light-transmitting plate 1 is located directly above the bracket 511, and the other group of light-transmitting plates 1 is unfolded from the other end and placed stably in the light-transmitting groove 3. When cleaning, the cleaning frame 513 moves up and down along the slide rail 512, and the cleaning roller 514 cleans the outer side of the outer plate 412 and the inner plate 411. After cleaning, the scraper 515 on the inner side of the cleaning frame 513 is moved out so that the scraper 515 is close to the surface of the inner plate 411 and the outer plate 412, and moves from top to bottom to clean the water stains on the surface of the light-transmitting plate 1. The cleaned light-transmitting plate 1 is always in the inside of the adjustment device body 2 until the next time the light-transmitting plate 1 is replaced for cleaning. When the light-transmitting plate 1 is in the inside of the adjustment device body 2 for a long time, when light is irradiated into the inside of the adjustment device body 2, the reflection of light by the internal reflector can increase the temperature inside the adjustment device body 2, thereby achieving the drying effect of the light-transmitting plate 1. This process will not hinder the light transmittance of the light-transmitting plate 1.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
