Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic power station, and particularly relates to a photovoltaic power station with adjustable angle. BACKGROUND

[0002] There is a very close relationship between the power generation efficiency of photovoltaic panels and the incident angle of sunlight. When sunlight is incident on the surface of photovoltaic panels at a perpendicular angle, the absorption efficiency of photovoltaic panels for light energy can reach the highest level, because the perpendicular incidence can enable the photovoltaic panels in a unit area to receive the most solar radiation energy. However, if the incident angle of light deviates greatly, the light energy that can be received by the photovoltaic panels will be significantly reduced due to the influence of cosine loss, thereby causing the power generation to decrease obviously. Especially in areas with unstable light conditions, the situation will be more prominent. In these places, by using a photovoltaic tracking system, the changes in the direction and intensity of light can be quickly responded to, and the angle of the photovoltaic panels can be adjusted in time to keep the photovoltaic panels at the best incident angle of sunlight as much as possible, thereby effectively reducing the fluctuation of power generation, improving the overall power generation efficiency and enhancing the stability of the system.

[0003] In the prior art, the photovoltaic power station with adjustable angle needs to be disassembled to complete the angle adjustment because the angle of light irradiation changes over time. However, repeated disassembly can cause the screws of the support to loosen, the connection to wear, thereby shortening the service life of the equipment and increasing the risk of failure. Therefore, it is necessary to provide a photovoltaic power station with adjustable angle. SUMMARY

[0004] In order to make up for the deficiencies of the prior art, the present application provides a photovoltaic power station with adjustable angle.

[0006] The bottom of the connecting plate is fixedly connected with a cross-shaped clamping groove, and the top of the positioning block is fixedly connected to the bottom of the cross-shaped clamping groove.

[0007] The top of the arc block is provided with a limiting groove, and the vertical shaft slides in the limiting groove.

[0008] The bottom of the worm wheel and the circular arc block is fixedly connected with a fixed plate, and the bottom of the fixed plate is fixedly connected with two groups of support assemblies.

[0009] The support assembly comprises a threaded rod, the top of the threaded rod is threadedly sleeved with a first sliding block, the bottom of the threaded rod is threadedly sleeved with a second sliding block, the surface of the first sliding block is hingedly connected with a plurality of load-bearing rods, the surface of the second sliding block is hingedly connected with a plurality of cross plates, and the plurality of cross plates are hingedly connected on one side of the load-bearing rod.

[0010] The end, away from the first sliding block, of the plurality of load-bearing rods is fixedly connected with a load-bearing block, and the surface of the circular arc block is embedded with a plurality of scale lines.

[0011] The bottom of the vertical shaft is fixedly connected with a clamping block, and the clamping block is slidingly connected to the inner wall of the limiting groove.

[0012] The present application has the advantages that: The connecting plate is arranged to provide a mounting position for the solar panel, and the positioning block serves as a connecting base; when the position of the solar panel needs to be adjusted, the rotating block is manually controlled to rotate the worm, and since the worm wheel is fixed to the surface of the fixed plate, the worm can rotate along the arc at the top of the circular arc block during rotation, so that the angle adjustment can be completed without disassembling the photovoltaic panel, and the photovoltaic panel does not need to be repeatedly disassembled, thereby avoiding screw loosening and connection wear and reducing the service life of the equipment.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Figure 1 and Figure 4The bottom of the connecting plate 1 is fixedly connected with a cross-shaped clamping groove 2, and the top of the positioning block 31 is fixedly connected to the bottom of the cross-shaped clamping groove 2. The cross-shaped structure of the cross-shaped clamping groove 2 can provide multi-directional positioning reference, ensure the connection direction of the positioning block 31 and the connecting plate 1 is accurate, avoid the solar panel 5 from being skewed during adjustment due to installation deviation, and ensure the accuracy of angle adjustment.

[0021] With reference to Figure 1 and Figure 4 , the top of the arc block 35 is provided with a limiting groove 38, and the vertical shaft 36 slides in the limiting groove 38. The limiting groove 38 provides stable guidance for the movement of the vertical shaft 36, avoids deviation, jamming or derailment of the vertical shaft 36 during adjustment, ensures that the angle change of the solar panel 5 always conforms to the preset trajectory, accurately aligns the sunlight, and maximizes the light energy absorption efficiency.

[0022] With reference to Figure 1 and Figure 4 , the bottom of the worm gear 34 and the arc block 35 is fixedly connected with a fixed plate 6, and the bottom of the fixed plate 6 is fixedly connected with two groups of support assemblies 4. The fixed plate 6 is arranged to facilitate the connection of the whole device, so as to avoid falling off during use and affecting the subsequent use effect.

[0023] With reference to Figure 1 and Figure 4 , the support assembly 4 comprises a threaded rod 41, the top of the threaded rod 41 is threadedly sleeved with a first sliding block 42, the bottom of the threaded rod 41 is threadedly sleeved with a second sliding block 44, the surface of the first sliding block 42 is hinged with a plurality of load-bearing rods 43, the surface of the second sliding block 44 is hinged with a plurality of cross plates 46, and the plurality of cross plates 46 are hinged on one side of the load-bearing rod 43.

When the first sliding block 42 and the second sliding block 44 approach, the load-bearing rod 43 is stretched outward, and the height of the whole support assembly 4 is increased. When the sliding block moves away, the load-bearing rod 43 is folded inward, and the height of the whole support assembly 4 is reduced. The support assembly 4 can be flexibly adjusted according to the installation terrain or the height requirement of the photovoltaic panel, so as to ensure that the fixed plate 6 and the structure above it are always in a horizontal and stable state.
