Solar panel installation for roof

technical field

The invention belongs to the technical field of photovoltaic modules, and in particular relates to a solar battery panel device for roofing.

Background technique

Facing the challenges brought by global climate change and energy security issues, human beings need to seek renewable energy, and solar energy is a clean and renewable energy. With the reduction of the cost of solar power generation, the photovoltaic industry has entered a new era of global development. At present, photovoltaic new energy power generation is developing rapidly. With the diversity of photovoltaic industry development and the scarcity of available land resources in coastal areas, photovoltaic agricultural greenhouses, photovoltaic animal husbandry greenhouses and household photovoltaic power generation systems are rapidly popularizing. The solar panel is the source of electricity generation, the efficiency of photovoltaic modules to convert solar energy directly determines the power generation efficiency, and the strength of the sun's rays directly determines the amount of power generated by the solar panel. In seasons with high light intensity and long light hours, the power generation is significantly higher; while in weaker light seasons, the power generation will be significantly reduced. Most of the top walls of the existing greenhouses are herringbone-shaped, and the solar panels are fixedly installed on the top walls of the greenhouses, so that there is always a top wall that cannot be irradiated with sunlight in the morning or afternoon. resulting in lower power generation efficiency.

Contents of the invention

The object of the present invention is to provide a solar panel device for roofing, so as to solve the problem of low power generation efficiency.

In order to achieve the above object, the basic solution of the present invention is: a solar panel device for roofing, including a solar panel and a frame, the solar panel is laid in the frame, and the frame includes a first frame and a second frame, the first The frame and the second frame are respectively laid on the two sides of the gable roof, and the first sprockets are provided on both sides of the ends of the first frame and the second frame that are far away from each other; the end of the first frame close to the second frame is provided with The first gear shaft with gear teeth is installed, the second frame is provided with the second gear shaft with gear teeth near the end of the first frame, a rotating shaft is arranged between the first gear shaft and the second gear shaft, and the two ends of the rotating shaft Both are equipped with incomplete gears, and the two incomplete gears mesh with the teeth of the first gear shaft and the second gear shaft respectively, and the teeth of the incomplete gears are located between the teeth of the first gear shaft and the gear teeth of the second gear shaft. Between the teeth, both ends of the rotating shaft are provided with a first transmission gear, the first transmission gear is meshed with a second transmission gear, one side of the second transmission gear is fixedly connected with a second sprocket, the second transmission gear and the second The sprockets are all rotatably connected to the first gear shaft, and the first sprocket and the second sprocket are equipped with chains; the first frame and the second frame are provided with guide rails, and slide rails are connected between the guide rails. On the ridge of the zigzag roof, a reflective structure is slidably connected to the slide rail, and the reflective structure is fixed on the chain.

The working principle of this basic scheme is that when the sun first rises, the sun shines from the east, and only the solar panels in the first frame can directly shine on the sun. Drive the rotating shaft to rotate forward. Since the rotating shaft is provided with an incomplete gear, the second frame is provided with a second gear shaft, and the teeth of the second gear shaft mesh with the incomplete gear, so the forward rotation of the rotating shaft can drive the second gear shaft to reverse Turn, so that the second frame can rotate upwards, so that the solar panel on the second frame can face the sunlight directly. Simultaneously because the incomplete gear only has gear teeth between the gear teeth of the first gear shaft and the gear teeth of the second gear shaft, so when the incomplete gear rotates forward, the incomplete gear will not be in contact with the gear on the first frame. The gear teeth of the shafts mesh so that the first frame remains unaffected. Since the first transmission gear is arranged on the rotating shaft, when the rotating shaft rotates, the first transmission gear will rotate accordingly. The first transmission gear is meshed with a second transmission gear, and one side of the second transmission gear is fixedly connected with a second sprocket, and both the second transmission gear and the second sprocket are rotatably connected to the first gear shaft. Therefore, the rotation of the first transmission gear will drive the rotation of the second transmission gear and the second sprocket, thereby driving the chain to drive on the first sprocket and the second sprocket. Since the reflective structure is fixed on the chain, the chain drive can drive the reflective structure. Sliding on rails and rails. Therefore, when the second frame turns to be on the same plane as the first frame and faces east, the reflective structure will slide from the slide rail to the guide rail, and then slide to the end of the second frame on the guide rail. At noon, the driving shaft is reversed, so that the second frame and the reflective structure return to their original positions. In the afternoon, when the sun shines from the west, only the solar panels in the second frame can get direct sunlight. The drive shaft is reversed to rotate the first frame upwards, and the reflective structure moves toward the end of the first frame, so that the first frame and the second frame are located on the same plane facing west, and the reflective structure is located at the end of the first frame.

The beneficial effect of this basic scheme is that: this scheme arranges an incomplete gear with only the upper half of gear teeth on the rotating shaft, so that when the rotating shaft rotates, the rotating shaft will only drive the first frame or the second frame to rotate upwards. The device can adjust the direction of the solar cell panel according to the direction of the sun, so that the solar cell panel can always face the sunlight, greatly improving the illuminated area and the illuminated time, thereby improving the power generation efficiency and power generation capacity. In this scheme, by setting a reflective structure, the reflective structure can reflect sunlight; since the reflective structure can move with the rotation of the first frame or the second frame, the reflected sunlight can shine on the two solar panels, Therefore, the light intensity is enhanced, the power generation efficiency of the battery panel is improved, the power generation capacity is greatly increased, and it has great practical value and economic benefits.

As a further improvement of this scheme, the reflective structure includes a storage box with an open upper end, and a reel is rotatably connected in the storage box, rotating gears are provided at both ends of the reel, reflective cloth is wound on the reel, and a cover plate is provided on the upper end of the reflective cloth. Both ends of the plate are provided with support rods, which are slidably connected to the containing box, and the support rods are provided with a rack structure meshing with the rotating gear. The advantage is that, as a reflective structure, the reflective cloth has a simple structure, high cost performance, and is easy to roll up. By setting the support rod, the cover plate and the storage box, the support rod will drive the cover plate to move downward when the reel rolls up the reflective cloth. Stores in storage case. It can prevent strong wind or heavy rain from damaging the reflective cloth and improve the service life of the reflective cloth.

As a further improvement of this solution, a cleaning structure is provided at the bottom of the containing box. The advantage is that when the reflective structure slides on the guide rail, the solar panel is cleaned by the cleaning mechanism provided at the bottom of the storage box, so that the surface of the solar panel is cleaner, thereby improving power generation efficiency and power generation.

As a further improvement of this solution, the cleaning structure includes a micro-air pump connected to a number of fan-shaped air nozzles, and the plurality of fan-shaped air nozzles are evenly distributed on the bottom of the containing box. The advantage is that by setting the micro-air pump and the fan-shaped air nozzle, the fan-shaped air nozzle can blow away the dust on the solar panel, improve the power generation efficiency, reduce the manual cleaning frequency of the solar panel, and save manpower.

As a further improvement of this solution, several ventilation holes are provided on the reflective cloth. The advantage is that the reflective cloth can withstand the wind with weak wind force by providing ventilation holes on the reflective cloth, thereby improving the utilization rate of the reflective cloth and prolonging the service life of the reflective cloth.

The first frame 10 is laid on the roof of the "herringbone" roof facing east, and the second frame 9 is laid on the roof of the "herringbone" roof facing west. One end of the first frame 10 near the second frame 9 is provided with a first gear shaft 11, and both ends of the first gear shaft 11 are provided with gear teeth; the end of the second frame 9 near the first frame 10 is provided with a second gear shaft 16. Both ends of the second gear shaft 16 are provided with gear teeth, and the gear teeth of the first gear shaft 11 are directly opposite to the gear teeth of the second gear shaft 16 . Both the first gear shaft 11 and the second gear shaft 16 are rotatably connected to the roof. A rotating shaft 4 is provided between the first gear shaft 11 and the second gear shaft 16 , and only incomplete gears 17 are provided at both ends of the rotating shaft 4 . The incomplete gear 17 meshes with the gear teeth of the first gear shaft 11 and the gear teeth of the second gear shaft 16 at the same time. The gear teeth of the incomplete gear 17 are located between the gear teeth of the first gear shaft 11 and the gear teeth of the second gear shaft 16 , that is, in a natural state, the gear teeth are located in the upper half of the incomplete gear 17 . Both ends of the rotating shaft 4 are provided with a first transmission gear 15 , on which a second transmission gear 13 meshes, and one side of the second transmission gear 13 is fixedly connected with a second sprocket 12 . The second transmission gear 13 and the second sprocket 12 are all rotatably connected on the first gear shaft 11, and the number of teeth of the first transmission gear 15 is several times of the number of teeth of the second transmission gear 13, so that the first transmission gear 15 rotates once , the second transmission gear 13 will rotate several circles. The first frame 10 is provided with a sprocket shaft at the end of one end away from the second frame 9, and the two ends of the sprocket shaft are all rotatably connected with the first sprocket, and the first sprocket is positioned at the outside of the rotating gear; the second frame 9 is far away from the first sprocket. One end of the frame 10 is provided with a sprocket shaft, and both ends of the sprocket shaft are rotatably connected to the second sprocket 12 . The first sprocket and the second sprocket 12 on the same side are all connected with a chain. Both sides of the first frame 10 and the second frame 9 are provided with guide rails 8, and a horizontally arranged slide rail 7 is connected between the guide rail 8 of the first frame 10 and the guide rail 8 of the second frame 9, and the slide rail 7 is located in a herringbone shape. On the ridge of the roof, the slide rail 7 is identical to the guide rail 8. A reflective structure is slidably connected on the slide rail 7 . The reflective structure includes a storage box with an open upper end, and rollers 6 are provided at both ends of the lower part of the storage box, and the rollers 6 are rollingly connected in the slide rail 7 . The inside of the containing box is connected with a reel for rotation, and the reel is wound with a reflective cloth 2, and the reflective cloth 2 is provided with a number of ventilation holes. The upper end of the reflective cloth 2 is provided with a cover plate 1, the two ends of the cover plate 1 are provided with support rods 3, and the support rods 3 are slidably connected to the containing box. The two ends of the spool are provided with rotating gears, and the support bar 3 is provided with a rack meshed with the rotating gears.

The cleaning structure includes a micro-air pump connected with four fan-shaped air nozzles, and the four fan-shaped air nozzles are evenly distributed on the bottom of the containing box.

During specific implementation, the reel is rotated in advance, because the reel is provided with a rotating gear, and the gear is meshed with a rack structure, so the reel rotates, and the rack structure will drive the support rod 3 to move upward. And the support bar 3 is connected with the cover plate 1, and the cover plate 1 is connected with the reflective cloth 2, so the reflective cloth 2 can be unfolded. The sun is just rising, and the sunlight shines from the east. At this time, only the solar panels 5 in the first frame 10 can directly shine on the sunlight. Drive the rotating shaft 4 to rotate forward, because the rotating shaft 4 is provided with an incomplete gear 17, the second frame 9 is provided with a gear shaft, and the gear teeth of the gear shaft mesh with the incomplete gear 17, so the forward rotation of the rotating shaft 4 can drive the gear shaft to reverse Turn, so that the second frame 9 can rotate upwards, so that the solar panel 5 on the second frame 9 can face the sunlight directly. Simultaneously, because the incomplete gear 17 only has gear teeth between the gear teeth of the first gear shaft 11 and the gear teeth of the second gear shaft 16, so when the rotating gear rotates forward, the rotating gear will not contact with the first frame 10. The gear teeth of the upper gear shaft are engaged, so the first frame 10 will not be affected. Since the rotating shaft 4 is provided with the first transmission gear 15, when the rotating shaft 4 rotates, the first transmission gear 15 will rotate together. The first transmission gear 15 is engaged with the second transmission gear 13 , and one side of the second transmission gear 13 is fixedly connected with the second sprocket 12 . Both the second transmission gear 13 and the second sprocket 12 are rotatably connected to the first gear shaft 11 , so the second sprocket 12 will rotate on the first gear shaft 11 when the rotating shaft 4 rotates. Since the number of teeth of the first transmission gear 15 is several times the number of teeth of the second transmission gear 13 , so that the first transmission gear 15 rotates once, the second transmission gear 13 will rotate several times. Thus the chain is driven on the first sprocket and the second sprocket 12 , and since the reflective structure is fixed on the chain, the chain transmission can drive the reflective structure to slide on the guide rail 8 . When the second frame 9 is rotated to be on the same plane as the first frame 10 , the reflective structure will move to the end of the second frame 9 . At the same time, the micro-air pump is turned on, and when the reflective structure slides, the four fan-shaped air nozzles at the bottom of the housing box can blow away the dust on the solar panel 5 . At noon, the drive rotating shaft 4 is reversed, so that the second frame 9 and the reflective structure return to their original positions. In the afternoon, the sun shines from the west, and only the solar panels 5 in the second frame 9 can directly shine on the sun. Drive the rotating shaft 4 to reverse, so that the first frame 10 rotates upwards, and the reflective structure moves toward the end of the first frame 10, so that the first frame 10 and the second frame 9 are located on the same plane, facing west, and the reflective structure is in the first frame 10 outer ends.
