Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panels, and in particular to a building facade decorative photovoltaic panel for generating electricity. Background Technology

[0002] Wall-mounted photovoltaic (PV) panels refer to photovoltaic power generation equipment installed on vertical surfaces such as building walls. They consist of multiple solar cells that convert sunlight into electrical energy. Their main function is to utilize the space on building surfaces to provide power to the building itself or surrounding facilities. They offer advantages such as not occupying additional land, high integration with buildings, and the ability to achieve distributed power generation, making them a crucial technological means to promote building energy conservation and the utilization of renewable energy.

[0003] However, only one photovoltaic panel can be installed in the same location, resulting in low power generation efficiency. Furthermore, the surface of the photovoltaic panel is relatively smooth, which easily generates glare, causing light pollution to pedestrians and significantly impacting their lives. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a building facade decorative photovoltaic panel, which aims to solve the technical problems of low power generation efficiency and easy light pollution of photovoltaic panels in the prior art.

[0005] To achieve the above objectives, this utility model proposes a decorative photovoltaic panel for building facades, comprising a main photovoltaic mounting plate and a secondary photovoltaic mounting plate. Both the main photovoltaic mounting plate and the secondary photovoltaic mounting plate are provided with photovoltaic panels. The secondary photovoltaic mounting plate is movably connected to the main photovoltaic mounting plate through a support component. The secondary photovoltaic mounting plate is also provided with a displacement component. The support assembly includes a telescopic support rod, one end of which is rotatably mounted on the inner wall of the main photovoltaic mounting plate, and the other end is movably mounted on the side end face of the secondary photovoltaic mounting plate. The displacement assembly includes a water collection tank, which is mounted on a rotating shaft via a pull rope. The rotating shaft is rotatably mounted inside the auxiliary photovoltaic mounting plate, and the water collection tank is provided with a flow-slowing hole.

[0006] Preferably, there are two water collection tanks, symmetrically arranged on both sides of the main photovoltaic mounting plate. Rotating wheels are provided on both sides of the main photovoltaic mounting plate, and the pull rope is wound around the wheels.

[0007] Preferably, the water collection tank has an upward-opening hollow interior, the slow-flow hole is the water outlet, the water outlet is opened at the bottom of the side end face of the water collection tank, a connecting plate is fixed on the water collection tank, the connecting plate is located at the water outlet, and a stop block is installed on the connecting plate by a spring. The stop block is a ball and abuts against the water outlet.

[0008] Preferably, the bottom of the main photovoltaic mounting plate is provided with a guide plate and a support block. There are two support blocks located on both sides of the guide plate. The support blocks protrude outward and their upper sides are sloped.

[0009] Preferably, the telescopic support rod has at least two parts, which are nested telescopically arranged. One end of the telescopic support rod abuts against the inclined surface of the support block. The guide plate is arc-shaped. Side grooves are opened on both sides of the auxiliary photovoltaic mounting plate to cooperate with one end of the telescopic support rod. A rotating auxiliary rod is provided on one side edge of the auxiliary photovoltaic mounting plate.

[0010] Preferably, the main photovoltaic mounting plate has a sliding groove inside, the rotating shaft slides in the sliding groove, and notches are also provided on both sides of the bottom of the main photovoltaic mounting plate. The telescopic support rod moves in the notches, and a rotating groove is also provided at the bottom of the notches. One end of the telescopic support rod is fixed with a rotating pin, which cooperates with the rotating groove.

[0011] Preferably, a diversion plate is fixed to the top of the main photovoltaic mounting plate. The diversion plate is convex in the middle and inwardly recessed on both sides, with the inwardly recessed positions of the two sides corresponding to the positions of the water collection tank.

[0012] Compared with the prior art, the beneficial effects of the decorative photovoltaic panel for building facades provided by this utility model are as follows: 1. By setting up the auxiliary photovoltaic mounting plate and the main photovoltaic mounting plate, under normal conditions, the auxiliary photovoltaic mounting plate slides downward under its own weight, causing the telescopic support rod to be pulled out and abut against the support block. This creates a certain angle between the auxiliary photovoltaic mounting plate and the main photovoltaic mounting plate. This not only achieves twice the power generation effect through the photovoltaic panels on the main photovoltaic mounting plate and the auxiliary photovoltaic mounting plate, but also blocks the reflection generated by the smooth surface of the photovoltaic panel, effectively preventing this reflection from shining on pedestrians on the road and causing light pollution.

[0013] 2. By using a water collection tank in conjunction with a diversion plate, rainwater can be collected quickly on rainy days. As the rainwater in the collection tank gradually increases in weight during the collection process, the rotating shaft can be pulled by a rope, thereby moving the secondary photovoltaic installation panel upwards until the secondary photovoltaic installation panel is completely retracted into the main photovoltaic installation panel. This can effectively protect the photovoltaic panels on rainy days, preventing them from being damaged by strong winds. At the same time, during the process of collecting rainwater in the collection tank, the surface of the photovoltaic panels can also be cleaned by the rainwater.

[0014] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0025] See Figure 1-5 This utility model provides a decorative photovoltaic panel for building facades, including a main photovoltaic mounting plate 10 and a secondary photovoltaic mounting plate 20. The main photovoltaic mounting plate 10 is mounted on a wall, and both the main photovoltaic mounting plate 10 and the secondary photovoltaic mounting plate 20 are equipped with photovoltaic panels. The secondary photovoltaic mounting plate 20 is movably connected to the main photovoltaic mounting plate 10 through a support assembly. The secondary photovoltaic mounting plate 20 is also equipped with a displacement assembly. The support assembly includes a telescopic support rod 22, one end of which is rotatably mounted on the inner wall of the main photovoltaic mounting plate 10, and the other end is movably mounted on the side end face of the secondary photovoltaic mounting plate 20.

[0026] The main photovoltaic mounting plate 10 has a guide plate 17 and a support block 16 at its bottom. Two support blocks 16 are located on either side of the guide plate 17, protruding outwards with a sloping upper surface. A telescopic support rod 22 consists of at least two nested telescopic parts, with one end abutting against the sloping surface of the support block 16. The guide plate 17 has an arc surface. Side grooves 21 are provided on both sides of the secondary photovoltaic mounting plate 20, cooperating with one end of the telescopic support rod 22. A rotating auxiliary rod 24 is provided on one edge of the secondary photovoltaic mounting plate 20. During the downward movement of the secondary photovoltaic mounting plate 20, the auxiliary rod 24 cooperates with the guide plate 17 to... The auxiliary photovoltaic mounting plate 20 can be moved diagonally downwards, thus forming a certain tilt angle. Through the arrangement of the auxiliary photovoltaic mounting plate 20 and the main photovoltaic mounting plate 10, under normal conditions, the auxiliary photovoltaic mounting plate 20 slides downwards under its own weight, causing the telescopic support rod 22 to be pulled out and abut against the support block 16. This allows the auxiliary photovoltaic mounting plate 20 and the main photovoltaic mounting plate 10 to form a certain angle. This not only achieves twice the power generation effect through the photovoltaic panels on the main photovoltaic mounting plate 10 and the auxiliary photovoltaic mounting plate 20, but also blocks the reflection generated by the smooth surface of the photovoltaic panel, effectively preventing this reflection from shining on pedestrians on the road and causing light pollution.

[0027] The displacement assembly includes a water collection tank 30, which is mounted on a rotating shaft 35 via a pull rope 31. The rotating shaft 35 is rotatably mounted inside the auxiliary photovoltaic mounting plate 20. The water collection tank 30 is provided with a flow-slowing hole. A diversion plate 11 is fixed on the top of the main photovoltaic mounting plate 10. The diversion plate 11 is convex in the middle and inwardly recessed on both sides. The position of the inward recesses on both sides is consistent with the position of the water collection tank 30. When it rains, rainwater from a large area can drip down along the diversion plate 11 into the water collection tank 30 and be collected by the water collection tank 30.

[0028] Two water collection tanks 30 are provided, symmetrically arranged on both sides of the main photovoltaic mounting plate 10. Rotating wheels 12 are located on both sides of the main photovoltaic mounting plate 10, and a pull rope 31 is wound around the wheels 12. The interior of the water collection tank 30 is a hollow structure with an upward opening. A slow-flow hole serves as the outlet 32. An outlet 32 ​​is also located at the bottom of the side end face of the water collection tank 30. A connecting plate 34 is fixed to the water collection tank 30, positioned at the outlet 32. A stop block 33, a spherical shape, is spring-loaded onto the connecting plate 34 and abuts against the outlet 32. At this point, the stop block 33 does not completely block the outlet 32, keeping it always open. The abutment of the stop block 33 restricts the discharge of rainwater from the water collection tank 30. The speed at which the rainwater is discharged is less than the speed at which it is collected. When the rainfall is small and the rainwater collection speed is less than the discharge speed from the outlet 32, the rainfall is too small to affect the photovoltaic panel. With the water collection tank 30 and the diversion plate 11, rainwater can be collected quickly on rainy days. During the rainwater collection process, the weight in the water collection tank 30 will gradually increase, and the rotating shaft 35 can be pulled by the pull rope 31, thereby moving the auxiliary photovoltaic mounting plate 20 upward until the auxiliary photovoltaic mounting plate 20 is completely retracted into the main photovoltaic mounting plate 10. This can effectively protect the photovoltaic panel on rainy days and prevent it from being damaged by strong winds. At the same time, during the rainwater collection process in the water collection tank 30, the surface of the photovoltaic panel can also be cleaned by the rainwater.

[0029] After the rain stops, the pressure of the rainwater in the water collection tank 30 will push the baffle 33 to compress the spring, slowly draining the water until all the water in the water collection tank 30 is drained. During this process, the weight of the water collection tank 30 gradually decreases. At this time, the weight of the auxiliary photovoltaic mounting plate 20 gradually becomes greater than that of the water collection tank 30, so the water collection tank 30 can be pulled upward by the pull rope 31. At this time, the auxiliary photovoltaic mounting plate 20 will move downward and return to the state before the rain.

[0030] The main photovoltaic mounting plate 10 has a sliding groove 13 inside, and the rotating shaft 35 slides in the sliding groove 13. The main photovoltaic mounting plate 10 also has notches 15 on both sides of the bottom, and the telescopic support rod 22 moves in the notch 15. The bottom of the notch 15 also has a rotating groove 14. One end of the telescopic support rod 22 is fixed with a rotating pin 23, which cooperates with the rotating groove 14.

[0031] Working principle: In use, the main photovoltaic mounting panel 10 can be fixedly installed on the wall. Under its own weight, the auxiliary photovoltaic mounting panel 20 will stretch the telescopic support rod 22, forming an angled extension with the main photovoltaic mounting panel 10. Sunlight shines on the photovoltaic panels on both the main and auxiliary photovoltaic mounting panels 10, achieving double the power generation efficiency. During rainy weather, wind may cause damage. Rainwater can be quickly collected into the water collection tank 30 via the drainage plate 11. During the rainwater collection process, the rainfall washes over the surface of the photovoltaic panels. As the weight of the collected rainwater in the collection tank 30 gradually exceeds that of the secondary photovoltaic mounting plate 20, it will be pulled upwards by the pull rope 31. At this time, the telescopic support rod 22 will gradually retract and rotate upwards until it enters the main photovoltaic mounting plate 10. At this point, the secondary photovoltaic mounting plate 20 is completely inserted into the main photovoltaic mounting plate 10, forming a whole. This can resist a certain amount of strong wind and prevent the main photovoltaic mounting plate 10 from being damaged by strong wind. When the weather clears up, the water in the collection tank 30 will drain out through the outlet 32, causing the weight of the collection tank 30 to gradually decrease. The secondary photovoltaic mounting plate 20 will then return to its natural state and continue to generate electricity.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
