Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation modules for a photovoltaic storage direct-flexible system, and in particular to a photovoltaic power generation module for a photovoltaic storage direct-flexible system. Background Art

[0002] Photovoltaic storage direct-flexible is a comprehensive energy supply system that integrates photovoltaic power generation, energy storage, DC power distribution and flexible power consumption. It achieves friendly interaction with the power grid through source-load interaction and is a form of new building power distribution system.

[0003] In the existing technology, photovoltaic power generation is an important component of the comprehensive energy supply equipment of light storage direct and flexible. Distributed solar photovoltaic power generation panels are usually built in the building area to provide sufficient energy for the entire system.

[0004] However, existing photovoltaic panels usually do not have rainproof function. Most of them provide waterproof performance of photovoltaic panels based on the waterproof performance of the materials of the photovoltaic panels themselves. But after a rainy day, a certain amount of rainwater will still remain on the photovoltaic panels. After being exposed to the sun, the photovoltaic panels are easily corroded, which reduces the service life of the photovoltaic panels. Summary of the invention

[0005] The object of the present invention is to provide a photovoltaic power generation module of a solar-storage direct-flexible system to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a support frame, a support plate is arranged on the top of the support frame, a photovoltaic power generation panel is arranged in the middle of the support plate, and the support frame is provided with clamping grooves on both sides of the photovoltaic power generation panel; and a stepper motor, the stepper motor is arranged on one side of the top of the support plate, the bottom of the stepper motor is connected to a retractable roller, the retractable roller is inserted into the inside of the support plate, and a tarpaulin is sleeved on the retractable roller, and both sides of the tarpaulin are clamped in the clamping grooves.

[0007] Preferably, the stepper motor can drive the retractable roller to rotate forward and reverse, so that the retractable roller retracts and unwinds the first gear sleeved on the retractable roller, so that the first gear covers the photovoltaic power generation panel, or exposes the photovoltaic power generation panel to the outside.

[0008] Preferably, a counterweight block is provided in the middle part of the bottom end of the tarpaulin, which can drive the tarpaulin to be inserted into the first water leakage port opened at the bottom end of the support frame along the inclination angle of the support plate, so as to cover the photovoltaic panel and prevent rainwater from corroding the photovoltaic panel. At the same time, rainwater can flow out from the first water leakage port from the surface of the tarpaulin along the inclination angle of the support plate.

[0009] Preferably, limit blocks are provided on both sides of the lower end of the awning, and the limit blocks are clamped in the clamping grooves on both sides of the support frame. The limit blocks can limit the awning to prevent the two sides of the awning from falling off from the clamping grooves, and at the same time prevent the retractable roller from over-reeling the awning and causing the awning to fall out of the clamping grooves.

[0010] Preferably, the retracting roller is provided with a first gear on both sides of the support plate, a second gear is provided on the outer side of the bottom end of the first gear, and the second gear is connected to the first roller shaft. The retracting roller can drive the first gear to mesh with the second gear and drive the first roller shaft on the second gear to rotate together.

[0011] Preferably, a second roller is provided at the bottom end of the first roller, and absorbent cloth is simultaneously sleeved on the first roller and the second roller. The absorbent cloth is tightly attached to the awning on the inner retractable roller. The absorbent cloth can be transmitted between the first roller and the second roller by the rotation of the first roller to absorb the rainwater remaining on the awning.

[0012] Preferably, two groups of support bars are provided at both ends of the inner side of the absorbent cloth, the support bars are located on both sides of the absorbent cloth, telescopic grooves are opened on the inner side of the support bars, springs are provided in the telescopic grooves, the inner side of the springs are connected to the water squeezing plates, and the springs can drive the water squeezing plates to contract.

[0013] Preferably, the water squeezing plate is tightly attached to the two sides of the absorbent cloth, and the water squeezing plate can fully squeeze the two sides of the absorbent cloth through the tension of the spring to squeeze out the rainwater absorbed by the absorbent cloth, thereby preventing the absorbent cloth from being over-wet, which causes the absorbent cloth to be unable to absorb rainwater on the awning cloth. The support plate is provided with a rain shield ring on the outside of the absorbent cloth, which can block the rainwater squeezed out of the absorbent cloth by the water squeezing plate, thereby preventing the rainwater from flowing onto the photovoltaic power generation panel along the inclination angle of the support plate and corroding the photovoltaic power generation panel. A second water leakage port is provided at the inner bottom of the rain shield ring, and rainwater can flow out of the support plate from the second water leakage port along the rain shield ring.

[0014] Preferably, a third water leakage port is opened in the middle part of the limit block, and the inner side of the top of the third water leakage port passes through the limit block and is parallel to the bottom end of the guide plate. The guide plate can guide rainwater to the third water leakage port opened in the middle, so that the third water leakage port can collect the water remaining on the awning.

[0015] Preferably, the limiting block is provided with a second telescopic groove in the middle of the bottom end of the third water leakage outlet, and a second spring is arranged in the second telescopic groove. The other end of the second spring is connected to a baffle, which can close the third water leakage outlet to prevent rainwater from flowing out. The top of the baffle is connected to an extension rod, which extends from the top of the limiting block. The top of the extension rod is connected to an extrusion block, and the inner wall of the top end can squeeze the extrusion block, so that the extrusion block squeezes the baffle through the extension rod to open the closure of the third water leakage outlet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention proposes a photovoltaic power generation module of a photo-storage direct-flexible system. When it is cloudy and about to rain, the stepper motor controls the retractable roller to reverse, so that the tarpaulin sleeved on the retractable roller is loosened, and the counterweight block in the middle of the bottom of the tarpaulin drives the tarpaulin to descend through gravity, so that the tarpaulin descends into the first water leakage opening opened at the bottom of the support frame. At this time, the tarpaulin completely covers the photovoltaic power generation panel arranged in the middle of the support frame. When it rains, rainwater falls on the tarpaulin and flows out from the first water leakage opening through the inclination angle of the support plate. The two sides of the tarpaulin are clamped in the clamping grooves opened on both sides of the support frame, so that the tarpaulin can completely cover the photovoltaic power generation panel. Limit blocks are arranged on both sides of the bottom end of the tarpaulin, and the limit blocks are clamped in the clamping grooves. The limit blocks limit the tarpaulin to prevent the tarpaulin from falling off from the clamping grooves, resulting in the tarpaulin being unable to cover the photovoltaic power generation panel.

The unwinding roller 9 rewinds and unwinds the first gear 10 sleeved on the rewinding roller 9, so that the first gear 10 covers the photovoltaic panel 3, or exposes the photovoltaic panel 3 to the outside; a counterweight block 6 is provided at the middle of the bottom end of the tarpaulin 5, and the counterweight block 6 can drive the tarpaulin 5 to be inserted into the first water leakage port 7 opened at the bottom end of the support frame 1 along the inclination angle of the support plate 2, so as to cover the photovoltaic panel 3 and prevent rainwater from corroding the photovoltaic panel 3. At the same time, rainwater can flow out from the first water leakage port 7 from the surface of the tarpaulin 5 along the inclination angle of the support plate 2;

[0028] Limiting blocks 11 are arranged on both sides of the lower end of the awning 5, and the limiting blocks 11 are clamped in the clamping grooves 8 on both sides of the support frame 1. The limiting blocks 11 can limit the awning 5 to prevent the two sides of the awning 5 from falling off from the clamping grooves 8, and at the same time prevent the retractable roller 9 from over-reeling the awning 5 and causing the awning 5 to fall out of the clamping grooves 8; the retractable roller 9 is provided with a first gear 10 on both sides of the support plate 2, and a second gear 12 is arranged on the outer side of the bottom end of the first gear 10, and the second gear 12 is connected to the first roller shaft 13, The unwinding roller 9 can drive the first gear 10 so that the first gear 10 meshes with the second gear 12 and drives the first roller 13 on the second gear 12 to rotate together; the bottom end of the first roller 13 is provided with a second roller 14, and the first roller 13 and the second roller 14 are both provided with a water-absorbing cloth 15, and the water-absorbing cloth 15 is closely attached to the tarpaulin 5 on the inner retracting and unwinding roller 9. The water-absorbing cloth 15 can be transmitted between the first roller 13 and the second roller 14 through the rotation of the first roller 13 to absorb the rainwater remaining on the tarpaulin 5;

[0029] Two sets of support bars 18 are provided at both ends of the inner side of the absorbent cloth 15. The support bars 18 are located on both sides of the absorbent cloth 15. A telescopic groove 19 is provided on the inner side of the support bars 18. A spring 20 is provided in the telescopic groove 19. The inner side of the spring 20 is connected to a water squeezing plate 21. The spring 20 can drive the water squeezing plate 21 to shrink. The water squeezing plate 21 is closely attached to both sides of the absorbent cloth 15. The water squeezing plate 21 can fully squeeze the two sides of the absorbent cloth 15 through the tension of the spring 20, squeeze out the rainwater absorbed on the absorbent cloth 15, and prevent the water from being absorbed. The cloth 15 is too wet, so that the absorbent cloth 15 cannot absorb the rainwater on the awning cloth 5; the support plate 2 is provided with a rain shield ring 16 on the outside of the absorbent cloth 15, and the rain shield ring 16 can block the rainwater squeezed from the absorbent cloth 15 by the squeezing plate 21, and prevent the rainwater from flowing along the inclination angle of the support plate 2 to the photovoltaic power generation panel 3 and corroding the photovoltaic power generation panel 3. The inner bottom of the rain shield ring 16 is provided with a second leaking port 17, and the rainwater can flow out of the support plate 2 from the second leaking port 17 along the rain shield ring 16;

[0030] A third water leakage opening 23 is provided in the middle part of the limiting block 11, and the inner side of the top of the third water leakage opening 23 passes through the limiting block 11 and is parallel to the bottom end of the guide plate 22. The guide plate 22 can guide rainwater to the third water leakage opening 23 provided in the middle part of 11, so that the third water leakage opening 23 can collect the rainwater remaining on the awning 5; the limiting block 11 is provided with a second telescopic groove 24 in the middle part of the bottom end of the third water leakage opening 23, and a second spring 25 is arranged in the second telescopic groove 24. The other end of the second spring 25 is connected to a baffle 26, and the baffle 26 can close the third water leakage opening 23 to prevent rainwater from flowing out. The top end of the baffle 26 is connected to an extension rod 27, and the extension rod 27 extends from the top end of the limiting block 11. The top end of the extension rod 27 is connected to an extrusion block 28, and the inner wall of the top end of 8 can squeeze the extrusion block 28, so that the extrusion block 28 squeezes the baffle 26 through the extension rod 27 to open the closure of the third water leakage opening 23.

[0031] In actual use, when it is cloudy and about to rain, the stepper motor 4 controls the retracting and releasing rollers 9 to reverse, so that the tarpaulin 5 sleeved on the retracting and releasing rollers 9 is loosened, and the counterweight block 6 in the middle of the bottom of the tarpaulin 5 drives the tarpaulin 5 to descend through gravity, so that the tarpaulin 5 descends to the first leaking hole 7 opened at the bottom of the support frame 1. At this time, the tarpaulin 5 completely covers the photovoltaic power generation panel 3 set in the middle of the support frame 1. When it rains, rainwater falls on the tarpaulin 5 and flows out from the first leaking hole 7 through the inclination angle of the support plate 2. The two sides of the tarpaulin 5 are clamped in the clamping grooves 8 opened on both sides of the support frame 1, so that the tarpaulin 5 can completely cover the photovoltaic power generation panel 3. Limiting blocks 11 are set on both sides of the bottom end of the tarpaulin 5, and the limiting blocks 11 are clamped in the clamping grooves 8. The limiting blocks 11 limit the tarpaulin 5 to prevent the tarpaulin 5 from falling off from the clamping grooves 8, resulting in the tarpaulin 5 being unable to cover the photovoltaic power generation panel 3;

[0032] When the rain stops and the sky clears, the stepper motor 4 controls the retractable roller 9 to rotate forward, so that the retractable roller 9 reels the awning 5. At the same time, the retractable roller 9 drives the first gear 10 on both sides of the retractable roller 9 to mesh with the second gear 12, so that the second gear 12 drives the first roller shaft 13 to rotate, so that the absorbent cloth 15 on the first roller shaft 13 and the second roller shaft 14 start to transmit, and the absorbent cloth 15 starts to absorb the remaining rainwater on the awning 5 to prevent the awning 5 from being mixed with rainwater when it is retracted, causing the awning 5 to be corroded by rainwater. While the absorbent cloth 15 is rotating, the squeezing plate 21 in the telescopic groove 19 on the inner side of the support bar 18 provided on one side of the absorbent cloth 15 starts to squeeze the absorbent cloth 15 through the tension of the spring 20, and squeezes out the rainwater absorbed on the absorbent cloth 15. The squeezed rainwater flows along the rain shield ring 16 provided on the outer side of the absorbent cloth 15, and then flows out from the second water leakage port 17 along the rain shield ring 16;

[0033] When the tarpaulin 5 is rolled up, rainwater remaining on the tarpaulin 5 may flow downward along the tarpaulin 5. At this time, the guide plate 22 at the bottom of the tarpaulin 5 begins to divert the rainwater, so that the rainwater flows into the third water leakage port 23 opened in the limit block 11 along the inclination angle of the guide plate 22, to prevent the rainwater from flowing from the tarpaulin 5 to the photovoltaic power generation panel 3 when the tarpaulin 5 is rolled up. At the same time, the baffle plate 26 at the bottom of the third water leakage port 23 closes the bottom of the third water leakage port 23 to prevent rainwater from flowing into the holding groove 8 and accumulating in the holding groove 8. The tarpaulin 5 continues to be rolled up. When it is rolled to the top end of the holding groove 8, the top inner wall of the holding groove 8 begins to squeeze the extrusion block 28, so that the extrusion block 28 pushes the baffle 26 through the extension rod 27 to squeeze the second spring 25 in the second telescopic groove 24, and squeezes the baffle 26 into the second telescopic groove 24, opening the closure of the baffle 26. At this time, the bottom of the third leakage port 23 is parallel to the leakage slot 29 opened at the bottom of the top end of the holding groove 8. Rainwater can flow out of the holding groove 8 from the leakage slot 29 through the third leakage port 23, fall onto the rain shield ring 16 inside the top of the support plate 2, and then flow out from the second leakage port 17 at the bottom of the rain shield ring 16.
