Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and more specifically, to a photovoltaic support protection device. Background Technology

[0002] Solar photovoltaic (PV) brackets are special brackets designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. They are generally made of aluminum alloy, carbon steel, and stainless steel. The advantages of solar support systems in supporting solar panels go far beyond simple production and installation; solar panels can also be moved flexibly according to sunlight and seasons.

[0003] To mitigate damage from strong lateral winds, existing solar photovoltaic (PV) mounting systems employ push rods. These push rods are automatically activated by sensors during strong winds, causing the PV panels to flip to a horizontal position, thus reducing the pressure from the wind and minimizing damage. However, the sensors and telescopic push rods not only increase the difficulty and workload of daily maintenance but also require additional electrical energy, contradicting the original purpose of using PV panels. Therefore, improvements are necessary. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a photovoltaic support protection device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic support protection device, comprising a photovoltaic panel, a protection adjustment component connected to the back of the photovoltaic panel, a support body fixedly connected to the bottom of the protection adjustment component, the protection adjustment component being connected to a position on the back of the photovoltaic panel that is not at the left or right center, and the protection adjustment component being connected to a position on the back of the photovoltaic panel that is not at the top or bottom center.

[0006] The protective adjustment assembly includes a protective component fixedly connected to the top of the support body. The protective component consists of a connecting sleeve, a positioning ring, a connecting shaft, a connecting rod, a spring, and two upper and lower limiting plates. The connecting sleeve is fixedly connected between the support body and the positioning ring. The connecting shaft is movably sleeved inside the positioning ring. The limiting plates, the connecting rod, and the spring are all installed inside the connecting sleeve. The two limiting plates are fixedly connected to the upper and lower ends of the connecting rod. The two ends of the spring are fixedly connected to the outer surface of the connecting rod and the inner wall of the connecting sleeve, respectively.

[0007] In a preferred embodiment of this invention, the outer diameter of the limiting plate is larger than that of the connecting rod, and the outer diameter of the limiting plate is adapted to the inner diameter of the connecting sleeve.

[0008] In a preferred embodiment of this invention, the inner diameter of the positioning ring is smaller than the outer diameter of the limiting plate, and the outer diameter of the connecting shaft is adapted to the inner diameter of the positioning ring.

[0009] As a preferred embodiment of this utility model, the lower end of the connecting shaft passes through the positioning ring and extends into the interior of the connecting sleeve and is fixedly connected to the top of a limiting plate at the upper end. The upper end of the connecting shaft passes through the positioning ring and is fixedly connected to an adjusting component. A connector is movably installed inside the adjusting component. The upper end of the connector is fixedly connected to the back of the photovoltaic panel. A positioning shaft is fixedly sleeved inside the connector. Both ends of the positioning shaft pass through the connector and are fixedly connected to the adjusting component.

[0010] As a preferred embodiment of this utility model, the adjustment assembly includes a connecting frame fixedly connected to the top of the connecting shaft, and the connecting head and the positioning shaft are both installed inside the connecting frame; adjustment limiting grooves are provided on both the left and right sides of the connecting frame, and an adjustment positioning screw is movably inserted inside the connecting head.

[0011] As a preferred embodiment of this utility model, both ends of the adjusting positioning screw pass through the connector and the adjusting limiting groove and extend to the outside of the connecting frame. One end of the adjusting positioning screw is connected to a nut, and the nut abuts against the outer surface of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Due to the protective components, the photovoltaic panel can swing along the top of the support body with the cooperation of the connecting sleeve and the limiting plate. Since the protective adjustment components are connected to the back of the photovoltaic panel at either the left or right end, the horizontal airflow can make the photovoltaic panel swing on its own. Therefore, when a strong horizontal airflow comes, the photovoltaic panel can be made parallel to it, thereby reducing the pressure of the horizontal airflow on the photovoltaic panel and effectively reducing the degree of damage to the support body.

[0014] 2. Due to the setting of the spring in this utility model, with the cooperation of the connecting rod and the spring, when the photovoltaic panel rotates, the spring can be twisted through the connecting shaft. Under the elastic recovery action, the photovoltaic panel can rotate in the opposite direction and reset itself.

[0015] 3. Due to the design of the connector, the photovoltaic panel can be easily tilted by the operator in conjunction with the connecting frame and the positioning shaft to ensure that it is under good lighting conditions. Furthermore, the adjusting positioning screw and its end nut can be used to fix the connector after the angle adjustment in conjunction with the adjusting limiting groove, thereby keeping the angle of the photovoltaic panel fixed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a photovoltaic support protection device, including a photovoltaic panel 1. A protection adjustment component 3 is connected to the back of the photovoltaic panel 1, and a support body 2 is fixedly connected to the bottom of the protection adjustment component 3. The protection adjustment component 3 is connected to a position on the back of the photovoltaic panel 1 that is not at the left or right center, and to a position on the back of the photovoltaic panel 1 that is not at the top or bottom center. Since the protection adjustment component 3 is connected to either the left or right end of the back of the photovoltaic panel 1, the horizontal airflow can cause the photovoltaic panel 1 to swing on its own. Therefore, when a strong horizontal airflow comes, the photovoltaic panel 1 can be made parallel to it, thereby reducing the pressure of the horizontal airflow on the photovoltaic panel 1 and effectively reducing the degree of damage to the support body 2. Since the connector 33 is connected to a lower position on the back of the photovoltaic panel 1, it has good support for the photovoltaic panel 1.

[0024] The protective adjustment assembly 3 includes a protective assembly 31 fixedly connected to the top of the support body 2. The protective assembly 31 consists of a connecting sleeve 311, a positioning ring 312, a connecting shaft 313, a connecting rod 315, a spring 316, and two upper and lower limiting plates 314. The connecting sleeve 311 is fixedly connected between the support body 2 and the positioning ring 312. The connecting shaft 313 is movably sleeved inside the positioning ring 312. The limiting plates 314, the connecting rod 315, and the spring 316 are all installed inside the connecting sleeve 311. The two limiting plates 314 are fixedly connected to the connecting rod 315. At the top and bottom ends of the connecting rod 315, the two ends of the spring 316 are fixedly connected to the outer surface of the connecting rod 315 and the inner wall of the connecting sleeve 311, respectively. Due to the setting of the protective component 31, the photovoltaic panel 1 can swing along the top of the bracket body 2 with the cooperation of the connecting sleeve 311 and the limiting plate 314. Due to the setting of the spring 316, with the cooperation of the connecting rod 315 and the spring 316, when the photovoltaic panel 1 rotates, the spring 316 can be twisted through the connecting shaft 313. Under its elastic recovery action, the photovoltaic panel 1 can rotate in the opposite direction and reset itself.

[0025] The outer diameter of the limiting plate 314 is larger than that of the connecting rod 315, and the outer diameter of the limiting plate 314 is compatible with the inner diameter of the connecting sleeve 311. Due to the setting of the limiting plate 314, the connecting rod 315 has a good support and positioning effect under the restriction of the connecting sleeve 311, thereby ensuring that the connecting rod 315 will not swing left and right and damage the spring 316.

[0026] The inner diameter of the positioning ring 312 is smaller than the outer diameter of the limiting plate 314, and the outer diameter of the connecting shaft 313 is matched with the inner diameter of the positioning ring 312.

[0027] The lower end of the connecting shaft 313 passes through the positioning ring 312 and extends into the interior of the connecting sleeve 311, and is fixedly connected to the top of a limiting plate 314 at the upper end. The upper end of the connecting shaft 313 passes through the positioning ring 312 and is fixedly connected to an adjusting component 32. A connector 33 is movably installed inside the adjusting component 32. The upper end of the connector 33 is fixedly connected to the back of the photovoltaic panel 1. A positioning shaft 34 is fixedly sleeved inside the connector 33. Both ends of the positioning shaft 34 pass through the connector 33 and are fixedly connected to the adjusting component 32. Due to the setting of the connector 33, with the cooperation of the connecting frame 321 and the positioning shaft 34, it is convenient for the staff to adjust the tilt angle of the photovoltaic panel 1 so that it is under a good lighting angle. Due to the setting of the adjusting positioning screw 323 and its end nut, the connector 33 after the angle adjustment can be fixed with the cooperation of the adjusting limiting groove 322, so that the angle of the photovoltaic panel 1 is kept fixed.

[0028] The adjustment assembly 32 includes a connecting frame 321 fixedly connected to the top of the connecting shaft 313. The connector 33 and the positioning shaft 34 are both installed inside the connecting frame 321. Adjustment limiting grooves 322 are provided on both the left and right sides of the connecting frame 321. An adjustment positioning screw 323 is movably inserted inside the connector 33. Due to the setting of the adjustment limiting grooves 322, the movement of the adjustment positioning screw 323 can be easily adjusted. In turn, with the cooperation of the positioning shaft 34, the adjustment positioning screw 323 can be easily adjusted to lock the connector 33 with the cooperation of the connecting frame 321, thereby fixing the angle of the photovoltaic panel 1.

[0029] Both ends of the adjusting positioning screw 323 pass through the connector 33 and the adjusting limiting groove 322 and extend to the outside of the connecting frame 321. One end of the adjusting positioning screw 323 is connected to a nut, which abuts against the outer surface of the connecting frame 321.

[0030] Working principle and usage process of this utility model:

[0031] Loosen the nut at the end of the adjusting positioning screw 323 by rotating it, which will release the locking between the adjusting positioning screw 323 and the connecting frame 321. At this time, with the cooperation of the positioning shaft 34 and the adjusting limit groove 322, the connecting head 33 can be rotated along the inside of the connecting frame 321, thereby adjusting the angle of the photovoltaic panel 1 so that it can receive sufficient sunlight. Finally, rotate the nut at the end of the adjusting positioning screw 323 in the opposite direction to clamp the adjusting positioning screw 323 with the connecting frame 321, which will fix the angle of the connecting head 33 and the photovoltaic panel 1 connected to its end.

[0032] When the horizontal airflow blows the photovoltaic panel 1, since the connection point between the photovoltaic panel 1 and the protective adjustment component 3 is not located in the middle left and right position on the back of the photovoltaic panel 1, the horizontal airflow can cause the photovoltaic panel 1 to drive the connecting shaft 313 to swing along the top of the protective component 31 under the restriction of the connecting sleeve 311 and the limiting plate 314 until the photovoltaic panel 1 is parallel to the airflow, which can greatly reduce the force of the horizontal airflow on the photovoltaic panel 1, thereby reducing the horizontal pressure on the support body 2.

[0033] When the limiting plate 314 rotates, it can twist the spring spring 316 through the connecting rod 315 with the cooperation of the connecting sleeve 311, thereby increasing its elastic restoring force. When the wind stops, the limiting plate 314 and the connecting rod 315 can rotate in opposite directions under its elastic restoring action, thereby resetting the photovoltaic panel 1.
