Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly relates to a distributed photovoltaic power generation device. Background Art

[0002] A distributed photovoltaic power generation panel refers to a system that installs the power generation equipment of a photovoltaic power generation system on the roof, open space or other suitable locations of a user's building and uses solar energy for power generation. This system is usually different from traditional large-scale centralized power stations. Its characteristic is that the power generation devices are distributed in various places and are close to electricity users. The existing photovoltaic power generation device mechanism includes a photovoltaic panel and a bracket. The bracket can be used to fix the mechanism, and the photovoltaic panel is inclined on the bracket to better contact sunlight and absorb solar energy.

[0003] However, in some areas with strong winds, when using a photovoltaic panel, the photovoltaic panel is eroded by the wind for a long time, making the connection points between it and the bracket not firm enough; especially when the photovoltaic panel is affected by the wind from the back, the damage degree of the wind to the photovoltaic panel is more serious. Over time, there is a risk that the photovoltaic panel will be overturned. Summary of the Invention

[0004] The purpose of the present invention is to provide a distributed photovoltaic power generation device to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A distributed photovoltaic power generation device includes a photovoltaic panel. A protective frame is fixedly sleeved outside the photovoltaic panel. A support frame is arranged outside the photovoltaic panel. A support rod is arranged between the support frame and the protective frame. A storage component is arranged outside the support rod; the storage component includes a limit block slidably arranged on the protective frame for limiting and supporting the slider. A slider is rotatably connected to the inside of the support rod near the end. The slider is slidably connected to the protective frame. An elastic member is arranged between the photovoltaic panel and the support frame. The storage component is used to drive the limit block to slide when the photovoltaic panel has a tendency to be overturned by strong wind, so that the photovoltaic panel is flatly stored in the support frame under the action of the elastic member.

[0007] Further, a guide groove is opened on the outer side of the protective frame. The slider slides inside the guide groove. A sliding hole is opened on the guide groove. The limit block slides inside the sliding hole. A sliding damping is also arranged between the limit block and the sliding hole.

[0008] Further, a pulling component is arranged on the storage component. The pulling component includes a pulling plate slidably arranged outside the support rod. A pulling member is fixedly connected to the outer end of the pulling plate. The pulling member is fixedly connected to the limit block. The limit block can be pulled to move by the pulling plate to remove the limit on the slider.

[0009] Furthermore, a buffer member is provided on the support rod. The buffer member includes a hollow rod and a top rod. A buffer plate that slides inside the hollow rod is fixedly connected to the end of the top rod. Buffer air holes are provided on the buffer plate. An activity groove is provided at the outer end of the hollow rod. A linkage block is provided inside the activity groove. Buffer springs are fixedly connected between the two ends of the linkage block and the activity groove respectively. A baffle is fixedly connected to the outer end of the linkage block. The support rod expands and contracts slightly under the action of wind force to achieve energy dissipation.

[0010] Furthermore, the pull plate is fixedly connected to the baffle. When the back of the photovoltaic panel faces the wind, it drives the linkage plate to move downward, and through the pulling member, the limiting block moves downward. Under the action of the elastic member, the photovoltaic panel rotates downward to complete the storage.

[0011] Furthermore, a compression spring is provided between the limiting block and the guide groove. Initially, the photovoltaic panel and the support rod form a 90-degree angle. When the front of the photovoltaic panel faces the wind, the support rod plays a supporting role for the photovoltaic panel. When the back of the photovoltaic panel faces the wind, the compression spring drives the included angle between the photovoltaic panel and the support rod to be greater than 90 degrees, facilitating the smooth rotation of the photovoltaic panel.

[0012] Furthermore, a rotating sleeve is fixedly connected to the end of the photovoltaic panel. A fixed rod is fixedly connected to the inner wall of the support frame. The rotating sleeve is movably sleeved outside the fixed rod. The bottom of the support frame is fixedly installed on the ground or the top surface of the building roof.

[0013] Furthermore, an adsorption member is provided inside the support frame. The adsorption member includes a support plate. A mounting plate is fixedly connected to the bottom surface of the photovoltaic panel. A buffer pad is fixedly connected to the bottom surface of the mounting plate. Magic tapes are provided on the top surface of the support plate and the bottom surface of the buffer pad to adsorb the photovoltaic panel when it is laid flat.

[0014] Furthermore, a rope sleeve rod is fixedly connected to the bottom surface of the support plate. An arc-shaped groove is provided at the outer end of the rope sleeve rod. The photovoltaic panel and the support plate are fixedly connected through an elastic member.

[0015] In the above technical solution, the beneficial effects of the distributed photovoltaic power generation device provided by the present invention are as follows:

[0016] When the wind is against the photovoltaic panel, after the photovoltaic panel is affected by the wind, the ejector rod moves relative to the hollow rod. The ejector rod drives the buffer plate to move and presses the buffer spring, and the external impact force is absorbed through gas pressure and the buffer spring, effectively reducing the damage to the photovoltaic panel. When the wind force is too strong, the buffer plate drives the limiting block to move through the pulling plate and the pulling member. Under the pulling force of the elastic member, the photovoltaic panel rotates downward and is received in the support frame, and the support frame protects it. At the same time, since the photovoltaic panel is in a flat state, the influence of the wind force is greatly weakened, and the wind-receiving area of the entire support frame will also be greatly reduced due to the flat laying of the photovoltaic panel, thereby reducing the damage to the photovoltaic panel caused by strong wind.

[0017] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not intended to limit the present disclosure.

[0018] This application document provides an overview of various implementations or examples of the technology described in the present disclosure, and is not a complete disclosure of the entire scope or all features of the disclosed technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] See also Figures 1-5 A distributed photovoltaic power generation device comprises a photovoltaic panel 1, the outside of which is fixedly sleeved with a protective frame 2, a support frame 3 is arranged on the outside of the photovoltaic panel 1, a support base is installed on the bottom of the support frame 3, a support rod 4 is arranged between the support frame 3 and the protective frame 2, and a storage component 5 is arranged on the outside of the support rod 4; the storage component 5 comprises a limit block 51 slidably arranged on the protective frame 2, which is used to limit and support a slider 55, the internal rotation of the support rod 4 near the end is connected with a slider 55, the slider 55 is slidably connected to the protective frame 2, and an elastic member 52 is arranged between the photovoltaic panel 1 and the support frame 3, and the storage component 5 is used to drive the limit block 51 to slide when the photovoltaic panel 1 is subject to strong wind and tends to be overturned, so that the photovoltaic panel 1 is flatly stored in the support frame 3 under the action of the elastic member 52.

[0032] A guide groove 53 is provided on the outer side of the protective frame 2, and the slider 55 slides inside the guide groove 53. A sliding hole 54 is provided on the guide groove 53. The limit block 51 slides inside the sliding hole 54. A sliding damping is also provided between the limit block 51 and the sliding hole 54. Anti-slip grooves are provided on the outside of the limit block 51, and there is friction between it and the sliding hole 54.

[0033] Specifically, the sliding damper includes a damping block with air holes formed therein. A sliding groove is provided on the sliding hole 54, and the damping block slides inside the sliding groove. By providing the air holes, the kinetic energy brought by the sliding is consumed, enabling it to stop quickly after the pulling force disappears, effectively avoiding continuous sliding under the action of inertia.

[0034] An end of the photovoltaic panel 1 is fixedly connected with a rotating sleeve 10. An inner wall of the support frame 3 is fixedly connected with a fixed rod 11. The rotating sleeve 10 is movably sleeved outside the fixed rod 11. The bottom of the support frame 3 is fixedly installed on the ground or the top surface of the building roof through a support base.

[0035] In this case, for areas with strong winds, the installation location is generally on the building roof where the wind force is relatively large at a high altitude.

[0036] When encountering strong winds, when the wind blows from the back of the photovoltaic panel 1, the strong wind force triggers the movement of the limiting block 51. Under the pulling force of the elastic member 52, the photovoltaic panel 1 can rotate quickly and be in a flat state, being received in the protection frame 2, so that it is no longer affected by the wind force impact, playing a good protective role for the photovoltaic panel 1, with a simple structure and ingenious design.

[0037] In a further embodiment provided by the present invention, a pulling member 6 is provided on the receiving member 5. The pulling member 6 includes a pulling plate 61 slidably disposed outside the support rod 4. An outer end of the pulling plate 61 is fixedly connected with a pulling member 62, and the pulling member 62 is fixedly connected with the limiting block 51. The limiting block 51 can be pulled to move by the pulling plate 61 to remove the limitation on the slider 55.

[0038] Please refer to Figure 6 In a further embodiment provided by the present invention, a buffer member 7 is provided on the support rod 4. The buffer member 7 includes a hollow rod 71 and a top rod 72. An end of the top rod 72 is fixedly connected with a buffer plate 73 slidable inside the hollow rod 71. Buffer air holes are formed in the buffer plate 73. An outer end of the hollow rod 71 is provided with a movable groove 74. A linkage block 75 is provided inside the movable groove 74. Buffer springs 76 are fixedly connected between two ends of the linkage block 75 and the movable groove 74 respectively. An outer end of the linkage block 75 is fixedly connected with a baffle 77. The support rod 4 can slightly expand and contract under the action of wind force to achieve energy dissipation.

[0039] The pulling plate 61 is fixedly connected with the baffle 77. When the back of the photovoltaic panel 1 faces the wind, it drives the linkage plate to move downward, and the limiting block 51 moves downward through the pulling member 62. Under the action of the elastic member 52, the photovoltaic panel 1 rotates downward to complete the receiving.

[0040] Specifically, a bottom of the top rod 72 is movably connected with a rotating shaft, and the rotating shaft is fixedly connected to an inner side surface of the protection frame 2.

[0041] Please refer to Figure 8 Figure 8 , when the wind is a headwind, after the photovoltaic panel 1 is affected by the wind, it pulls the hollow rod 71 to move, causing the ejector rod 72 to move relative to the hollow rod 71. The ejector rod 72 drives the buffer plate 73 to move and presses the buffer spring 76. The external impact force is absorbed through gas pressure and the buffer spring 76, effectively reducing the damage to the photovoltaic panel 1. When the wind force is too large, the buffer plate 73 drives the limit block 51 to move through the pull plate 61 and the pulling member 62. The limit block 51 separates from the slider 55. Without the block of the limit block 51, under the pulling force of the elastic member 52, the photovoltaic panel 1 rotates downward and is received in the support frame 3. The support frame 3 protects it. At the same time, since the photovoltaic panel 1 is in a flat state, the influence of the wind force is greatly weakened, and the windward area of the entire support frame 3 will also be greatly reduced due to the flat laying of the photovoltaic panel 1, thereby reducing the damage of strong wind to the photovoltaic panel 1.

[0042] A compression spring 8 is arranged between the limit block 51 and the guide groove 53. Initially, the photovoltaic panel 1 and the support rod 4 form a 90-degree angle. When the front side of the photovoltaic panel 1 faces the wind, the support rod 4 plays a supporting role for the photovoltaic panel 1. When the back side of the photovoltaic panel 1 faces the wind, the compression spring 8 drives the included angle between the photovoltaic panel 1 and the support rod 4 to be greater than 90 degrees, facilitating the smooth rotation of the photovoltaic panel 1.

[0043] Furthermore, when the front side of the photovoltaic panel 1 faces the wind, the support rod 4 can achieve the best support effect and can be set at a 90-degree included angle. In this way, when the front wind strengthens, the ejector rod 72 moves upward relative to the hollow plate, and the linkage block 75 moves to the end. At this time, the support rod 4 no longer contracts but supports the photovoltaic panel 1. The support force at this angle is the largest. If the angle is greater than 90 degrees, part of the pressure will be converted into the extrusion of the limit block 51, not only reducing the support effect of the device on the photovoltaic panel 1 but also posing a hazard to damaging the device structure.

[0044] Furthermore, when the back side of the photovoltaic panel 1 faces the wind, the support rod 4 cannot support the photovoltaic panel 1. Therefore, the photovoltaic panel 1 needs to be received. When the limit block 51 moves, the compression spring 8 will push the slider 55 to move, making the included angle between the hollow rod 71 and the photovoltaic panel 1 greater than 90 degrees. The best expansion angle is 100 - 120 degrees. At this time, under the elastic force of the elastic member 52, it rotates downward to smoothly complete the rapid reception of the photovoltaic panel 1.

[0045] Please refer to Figure 7 Figure 7 , in the further provided solution of the present invention, an adsorption component 9 is arranged inside the support frame 3. The adsorption component 9 includes a support plate 91. A mounting plate 92 is fixedly connected to the bottom surface of the photovoltaic panel 1, and a buffer pad 93 is fixedly connected to the bottom surface of the mounting plate 92. Magic tapes are arranged on the top surface of the support plate 91 and the bottom surface of the buffer pad 93 to adsorb the photovoltaic panel 1 when it is laid flat through the magic tapes.

[0046] A rope - sleeving rod 12 is fixedly connected to the bottom surface of the support plate 91. An arc - shaped groove is formed at the outer end of the rope - sleeving rod 12. The photovoltaic panel 1 and the support plate 91 are fixedly connected through an elastic member 52.

[0047] By arranging the buffer pad 93, damage to the photovoltaic panel 1 caused by too fast rotation speed can be avoided. The buffer cotton is arranged inside the buffer pad 93, which can effectively reduce the impact force. At the same time, the magic tape adopts the industrial strong - type magic tape, which can bear a tensile force of 5 - 15 kg. At the moment when the magic tape is attached, the photovoltaic panel 1 will be adsorbed inside the support frame 3 and will no longer shake upwards, effectively avoiding the photovoltaic panel 1 hitting the support plate 91 repeatedly under external impact, and further reducing the damage to the photovoltaic panel 1.

[0048] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above - mentioned drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
