Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and particularly relates to a photovoltaic power generation device with good wind resistance performance. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels (modules), controllers, and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device; photovoltaic power generation devices are usually laid in the wild.

[0003] The patent with the patent number CN202021849999.4 discloses a wind and hail resistant photovoltaic power generation device, belonging to the field of photovoltaic power generation, including a base, a rotating frame, a photovoltaic panel, a hydraulic cylinder, a mounting frame, an interception frame, a guide groove, a guide frame, a guide block, and an interception net. The device rotatably installs the photovoltaic panel through the rotating frame on the base. When strong convective weather such as strong wind or thunderstorm occurs, the hydraulic cylinder acts to contract and drive the rotating frame to rotate downward until the photovoltaic panel rotates to a horizontal state. Furthermore, the photovoltaic panel in the horizontal state reduces the area in the horizontal direction and reduces the action of wind force on the photovoltaic panel. When the photovoltaic panel descends, the guide block on the guide frame acts on the interception frame, and then drives the interception frame to descend and finally fall on the upper surface of the photovoltaic panel. Furthermore, the interception net on the interception frame is used to protect the photovoltaic panel to prevent direct impact of hail or other sundries. Although the above photovoltaic power generation device can achieve the purpose of wind resistance, in the actual use process, it is difficult to monitor the wind force situation in the actual situation, and manual monitoring and operation are required, which increases the labor cost. At the same time, power equipment such as hydraulic cylinders need to be installed, which greatly increases the installation and use cost of the equipment and has great limitations.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present invention.

[0032] A photovoltaic power generation device with good wind resistance performance provided in the present invention is referred to Figures 1-7 , including

[0033] A support base 1, which is set in a U shape, and long grooves are opened on the inner walls of its opposite sides; two mounting rods 2 are fixed on both sides of the top of the support base 1;

[0034] A wind power plate 201, which is rotatably connected between the two mounting rods 2; and a wind power opening and closing limiter is arranged on one side of the support base 1; before the wind force reaches the preset threshold, the wind power opening and closing limiter keeps the wind power plate 201 in a fixed state, and when the wind force reaches the preset threshold, the wind power opening and closing limiter allows the wind power plate 201 to start rotating;

[0035] A photovoltaic panel 101, the two ends of which are rotatably connected to the support base 1; a sliding rod 102 is slidably arranged in the two long grooves, first compression springs 100 are arranged between the sliding rod 102 and the inner walls of the long grooves, and a connecting rod 103 is arranged between the sliding rod 102 and the photovoltaic panel 101, and the ends of the two connecting rods 103 are rotatably connected to the photovoltaic panel 101 and the sliding rod 102; and

[0036] Wind-triggered automatic adjustment mechanism, which includes a driven rod 106 and a locking member. The locking member is arranged between the driven rod 106 and the sliding rod 102 for locking the sliding rod 102. The driven rod 106 is slidably connected to the support base 1 through a second compression spring 109, enabling it to displace in the vertical direction. The upper end of the driven rod 106 is provided with a U-shaped rod 110. The two ends of the U-shaped rod 110 are respectively located on both sides of the wind plate 201. When the wind force reaches a preset threshold, the wind plate 201 starts to rotate and presses down the U-shaped rod 110. When the driven rod 106 is triggered to move through the U-shaped rod 110, the locking of the sliding rod 102 by the locking member is released, and then the sliding rod 102 moves backward under the action of the first compression spring 100, so that the photovoltaic panel 101 is laid flat.

[0037] In this embodiment, referring to Figures 1-4 , the support base 1 serves as the basic support of the entire device. The long slots opened on the inner walls of its two sides are for the movement of the sliding rod 102, allowing the photovoltaic panel 101 to be adjusted between different inclination angles to optimize sunlight absorption. Before the wind force reaches the preset threshold, the wind opening and closing limiter keeps the wind plate 201 fixed to prevent it from rotating randomly under low wind force. When the wind force reaches the preset threshold, the limiter allows the wind plate 201 to start rotating to adapt to the wind force change. The wind-triggered automatic adjustment mechanism releases the lock through the interaction of the driven rod 106 and the locking member when the wind force reaches the preset threshold, allowing the sliding rod 102 to move under the action of the first compression spring 100, so that the photovoltaic panel 101 is laid flat, reducing the direct impact of the wind on the photovoltaic panel 101 and improving the stability and safety of the system.

[0038] Therefore, when the wind force of the device reaches the design threshold, the limiter allows the wind plate 201 to rotate. The rotation of the wind plate 201 is transmitted to the driven rod 106 through the U-shaped rod 110, causing the driven rod 106 to displace under the action of the second compression spring 109. The displacement of the driven rod 106 releases the locked state of the sliding rod 102 by the locking member, allowing the sliding rod 102 to move backward under the action of the first compression spring 100. The backward movement of the sliding rod 102 drives the connecting rod 103, and then the photovoltaic panel 101 changes from an inclined state to a horizontal state, which can reduce wind resistance and protect the photovoltaic panel 101 from strong wind damage. The device utilizes the interaction between wind force and springs to achieve automatic adjustment of the photovoltaic panel 101, improving the wind resistance and service life of the entire device. Overall, through the dynamic adjustment and limit protection mechanism, the device significantly improves the stability and durability of the photovoltaic power generation device under strong wind conditions. The device can self-adjust to adapt to different wind speeds, reduce damage caused by wind force, and thus ensure long-term energy output and economy.

[0039] Specifically, referring to Figures 1-2The wind-powered opening and closing limiter includes a slide rail 202, a second rack 203, a second gear 204 and a third compression spring 205. The slide rail 202 is arranged on one side of the support base 1 to provide a sliding path for the second rack 203. The second rack 203 is slidably arranged on the inner side of the slide rail 202. Third compression springs 205 are arranged on both sides of the second rack 203. One end of the third compression spring 205 is fixedly connected to the outer side of the second rack 203, and the other end is fixedly connected to the slide rail 202. The third compression spring 205 is used to enable the second rack 203 to move accordingly when the wind force changes when the wind force reaches a set threshold. The third gear is coaxially fixed to one end of the rotating shaft of the wind plate 201, and the second gear 204 is meshed with the second rack 203 to realize the rotation of the wind plate 201 through gear transmission. When the wind force is relatively small (not reaching the predetermined threshold), the third compression springs 205 on both sides fix the second rack 203 in the initial position. At this time, the second gear 204 meshes with the second rack 203, and the wind board 201 remains fixed. When the wind force gradually increases and reaches the preset threshold, the wind force on the wind board 201 increases and is transmitted to the second gear 204 through the rotating shaft. The increase in wind force overcomes the resistance of the third compression spring 205, pushing the second rack 203 to slide forward in the slide rail 202. In this process, the third compression spring 205 on one side of the second rack 203 is further compressed. As the second rack 203 moves, the second gear 204 starts to rotate. Since the second gear 204 is coaxially fixed with the rotating shaft of the wind plate 201, the wind plate 201 also begins to rotate. After the wind plate 201 rotates to press down the U-shaped rod 110, the U-shaped rod 110 presses down the driven rod 106, causing the driven rod 106 to be displaced under the action of the second compression spring 109. The displacement of the driven rod 106 realizes the release of the locking state of the locking member on the sliding rod 102.

[0040] Reference Figure 5 The two ends of the slide rail 202 are closed, which can ensure that the second rack 203 will not separate from the slide rail 202 during the sliding process, thereby enhancing the stability and reliability of the system.

[0041] Specifically, refer to Figures 5-6, the locking member includes a fixing rod 11, a first rack 104, a first gear 105 and a clamping block 107. The fixing rod 11 is installed on the support base 1, located between the driven rod 106 and the sliding rod 102, and is used to provide support and positioning functions. The first gear 105 is rotatably connected to the fixing rod 11. The first rack 104 is fixed to the middle of the sliding rod 102. The first gear 105 is meshed with the first rack 104. The first rack 104 can be unlocked and locked by the free rotation of the first gear 105 to realize the sliding of the sliding rod 102. The clamping block 107 is fixed to the front side of the bottom end of the driven rod 106 (the lower end of the driven rod 106 is arranged in a U shape), and the clamping block 107 is engaged with the first gear 105 to prevent the first gear 105 from rotating freely. When the wind force does not reach the preset threshold, the driven rod 106 remains stationary, and the clamping block 107 is engaged with the first gear 105 to fix the first gear 105. Since the first gear 105 is meshed with the first rack 104, the first rack 104 is also locked, and the sliding rod 102 cannot move. When the wind force increases to the preset threshold, the wind power plate 201 starts to rotate, and the driven rod 106 moves downward through the U-shaped rod 110. When the driven rod 106 moves downward, the clamping block 107 no longer blocks the first gear 105, and the first gear 105 can rotate freely. Since the first gear 105 is meshed with the first rack 104, the elastic restoring force of the first compression spring 100 is used to drive the displacement of the first rack 104, and the sliding rod 102 moves backward under the action of the first compression spring, driving the photovoltaic panel 101 to be laid flat to protect the photovoltaic panel 101.

[0042] Refer to Figure 5 , on the upper and lower sides of the support plate 10 provided on the support base 1 outside the driven rod 106, a group of circular plate-shaped limit plates 108 are fixedly arranged to ensure the displacement limit of the driven rod 106 in the vertical direction and prevent the driven rod 106 from moving excessively. Through the setting of the limit plates 108, the movement of the driven rod 106 is restricted within a safe range, avoiding mechanical failures or damages caused by excessive movement, improving the stability and reliability of the entire system, reducing wear and fatigue caused by excessive displacement, and thus extending the service life of the equipment.

[0043] Refer to Figure 6 , the clamping block 107 is wedge-shaped. The wedge design enables the clamping block 107 to generate a larger contact area and friction force when engaged with the first gear 105, thereby improving the reliability of locking.

[0044] Specifically, a buffer layer is provided on the outer surface of the wind power plate 201, which helps to reduce the impact force generated when the wind power plate 201 collides with the U-shaped rod 110 during operation; the buffer layer is usually made of soft or elastic materials (such as rubber material), which can absorb energy and reduce the impact force, thereby protecting the wind power plate 201 itself.

[0045] Specifically, the material of the support base 1 is made of a high-strength and corrosion-resistant material, such as (made of steel plate or alloy plate).

[0046] Implementation principle: When encountering severe weather such as strong winds (reaching the set threshold), the strong wind will blow the wind power plate 201 to rotate on the tops of the two sets of mounting rods 2 and blow down the wind power plate 201. Whether the wind power plate 201 is blown forward or backward, it can press on the driven rod 106 and drive the driven rod 106 to slide downward along the support base 1. During this process, the block 107 can be driven to move downward and lose the limiting effect on the first gear 105. Under the action of the first compression spring 100 in the long strip grooves on both sides of the inner wall of the support base 1, the sliding rod 102 is pushed to slide rapidly backward along the long strip groove, thereby driving the connecting rod 103 to move and making the angle of the photovoltaic panel 101 flat, and the photovoltaic panel 101 is retracted inside the support base 1, reducing the impact of strong winds on the photovoltaic panel 101, avoiding the phenomenon that the photovoltaic panel 101 is blown away or damaged by the wind force, and effectively protecting the photovoltaic panel 101 in strong wind weather; when there is no wind or the wind force is small (not reaching the preset threshold), the two sets of third compression springs 205 on both sides inside the slide rail 202 can limit the second rack 203, fix the second rack 203 in the middle area of the slide rail 202, so that the second rack 203 can limit the angle of the second gear 204 and the wind power plate 201, keeping the wind power plate 201 in a vertical state, and thus ensuring the wind monitoring effect of the wind power plate 201.

[0047] The above is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the specification and illustrated content of the present invention should be included in the protection scope of the present invention.
