Description

A wind-resistant photovoltaic power generation buffer support

Technical Field

The utility model relates to the technical field of photovoltaic installation, in particular to a wind-resistant photovoltaic power generation buffer bracket.

Background Art

Photovoltaic power generation is a clean and renewable energy source. However, due to the lack of effective wind resistance measures, existing photovoltaic power generation equipment will experience severe vibrations in strong wind environments, which not only affects the power generation efficiency but also shortens the service life of the equipment. Therefore, how to improve the wind resistance of photovoltaic power generation equipment has become an urgent problem to be solved.

The prior art (Chinese patent number: CN218352447U) discloses a wind-resistant and high-stability photovoltaic power generation device, which can use a first frame and a second frame to be softly connected through multiple buffers. When the frame is deformed, the buffers are deformed and buffered to reduce the vibration and deformation. At the same time, the damper plays a role of stable support, making the overall wind resistance stronger and more stable. However, in actual use, the strong wind in the external environment is mostly unstable in direction, and the wind force is either large or small. When the wind force is too strong, because its windward surface is fixed, it is impossible to reduce the wind force it bears, which can easily cause damage to the photovoltaic power generation equipment.

A wind-resistant photovoltaic power generation buffer bracket shown in Figure 1 includes two vertical plates 1, the bottom surfaces of the vertical plates 1 are fixedly connected to the ground or other stable installation platforms, the two vertical plates 1 are arranged opposite to each other, a connecting plate 2 is fixedly connected between the two vertical plates 1, and slide grooves 3 and give-way grooves 4 are respectively provided on the sides of the vertical plates 1, and a buffer component is arranged in the give-way groove 4, and a vibration reduction component is transmission-connected at both ends of the buffer component, the vibration reduction component is slidably connected to the slide groove 3, a fixed plate 5 is fixedly connected between the two vibration reduction components, and a plurality of adjustment components for adjusting the angle of the photovoltaic panel 6 are fixedly connected to the top surface of the fixed plate 5, and the photovoltaic panel 6 is fixedly installed on the adjustment component.

The utility model utilizes two vertical plates 1 to stably support a buffer bracket, and utilizes a vibration reduction component to offset the blowing force of strong external wind received by the photovoltaic panel. When the wind force is greater than the offsetting force of the vibration reduction component, the buffer component will be utilized to further consume the energy of the wind, gradually consume the severe wind force, and convert it into green electric energy for utilization.

Furthermore, a plurality of connection holes are provided on the side of the vertical plate 1, through which a plurality of the utility models can be fixedly connected together, thereby improving the overall wind resistance.

As a further optimized solution, as shown in FIG2 , the buffer assembly includes two gears 7, which are meshed and transmission-connected with the vibration reduction assembly. The gear 7 is arranged in the clearance groove 4, and the gear 7 and the clearance groove are clearance-matched to avoid interference with the gear 7. A transmission shaft 8 is fixedly connected to the center of the gear 7, and one end of the transmission shaft 8 is transmission-connected to a generator 9 of a rotor, and the generator 9 is fixedly connected to the top surface of the connecting plate 2.

A further optimized solution, as shown in FIG3 , is that the vibration reduction assembly includes a slide bar 10, the bottom surface of which is provided with a rack meshing with the gear 7 (conventional technology, not shown in the figure), and the side of the slide bar 10 is fixedly connected to the side of the fixed plate 5, and the slide bar 10 is driven by the fixed plate 5 to achieve sliding. The two end surfaces of the slide bar 10 are respectively fixedly connected with springs 11, and the spring 11 is fixedly connected to the end surface of the chute 3. The spring 11 can accumulate wind force and absorb it through the buffer assembly. A limit plate 12 is fixedly connected to the side of the chute 3 away from the connecting plate 2, and the limit plate 12 is slidably connected to the side of the slide bar 10. The limit plate 12 can cooperate with the fixed plate 5 to limit the slide bar 10 in the chute 3 and maintain a sliding connection with the chute 3.

Furthermore, a limiting column 18 is provided at one end of the spring 11, one end of the limiting column 18 is fixedly connected to the end face of the slide groove 3, and the other end of the limiting column 18 is detachably connected to the end face of the slide bar 10. The limiting column 18 can be used to limit the sliding range of the slide bar 10 in the slide groove 3, thereby avoiding excessive compression of the spring 11 due to excessive wind force.

Further optimization scheme, the adjustment component includes a mounting frame, a hydraulic cylinder 15 is hinged in the middle of the mounting frame, and an articulated seat 16 is hinged at one end of the hydraulic cylinder 15. The hydraulic cylinder 15 maintains an angle between 5° and 85° with the top surface of the fixed plate to prevent the adjustment component from getting stuck. The mounting frame and the articulated seat 16 are respectively fixedly connected to the top surface of the fixed plate 5; the top surface of the mounting frame is fixedly connected to the photovoltaic panel 6; one end of the mounting frame is hinged to the fixed plate 5.

Further optimizing the scheme, the mounting frame includes two side bracing plates 13 and a transverse bracing plate 14, the two ends of the transverse bracing plate 14 are respectively fixedly connected to the two side bracing plates 13, the side bracing plates 13 and the transverse bracing plates 14 are respectively fixedly connected to the photovoltaic panels 6, and a hinge groove is provided at the bottom end of the transverse bracing plate 14, and the transverse bracing plate 14 is hinged to the piston rod of the hydraulic cylinder 15 through the hinge groove; one end of the side bracing plate 13 is hinged to the top surface of the fixed plate 5. The hinge seat 16 is arranged away from the place where the side bracing plates 13 and the fixed plate 5 are hinged to each other.

To further optimize the solution, a limit block 17 is arranged between the articulated seat 16 and the cross brace plate 14. A groove matching the side of the hydraulic cylinder 15 is provided on the top surface of the limit block 17. The limit block 17 can limit the angle between the hydraulic cylinder 15 and the fixed plate 5 to prevent the hydraulic cylinder 15 from getting stuck and unable to rise or fall after shrinking to a horizontal state.

The working process of this embodiment is as follows:

The utility model is placed in an area exposed to direct sunlight and fixedly connected to the mounting platform. The hydraulic cylinder 15 is started and the piston rod of the hydraulic cylinder 15 is extended to lift the mounting frame. Since one end of the mounting frame is hinged to the top surface of the fixing plate 5, the other end of the mounting frame will deflect along its hinge, making it easier for the photovoltaic panel 6 fixedly mounted on the mounting frame to be aligned with the sunlight.

When the wind in the external environment becomes stronger, the wind blows onto the photovoltaic panel 6, which will give it a certain lateral force. When the lateral force is greater than the tension of the spring 11, the fixed plate 5 drives the slide bar 10 to slide in the slide groove 3. The sliding of the slide bar 10 will drive the rack and gear 7 to rotate. The rotation of the gear 7 drives the generator 9 to rotate. The generator 9 is electrically connected to an external energy storage device (existing technology, not shown in the drawings), which ultimately consumes the wind energy and converts it into electrical energy storage.

As shown in Figure 4, when the external wind force is too strong or the wind force is not opposite to the photovoltaic panel, in order to prevent the entire vibration reduction assembly and the buffer assembly from moving violently and frequently to cause damage to the entire device, the hydraulic cylinder 15 is started to retract, and the angle between the mounting frame and the fixed plate 5 is reduced to the minimum, thereby maximizing the reduction of the windward surface of the photovoltaic panel 6 and reducing the wind force received by the utility model.

The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
