[0004] In the aforementioned patent, the photovoltaic panel protection device has anti-slip grooves and slots on the surface of the enclosure frame for sliding adjustment of the position of the protective plate and elastic connecting piece. The protective plate and elastic connecting piece are stretched to protect the photovoltaic panel above, thus providing protection for the photovoltaic panel. However, when encountering physical influences such as strong winds or mechanical impacts, the photovoltaic panel may be damaged, affecting normal use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a protection device for new energy photovoltaic panels, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a new energy photovoltaic panel protection device, comprising: a support frame, the support frame being disposed on the ground; a fixing frame, the fixing frame being fixedly installed on the top of the support frame; a support plate, the support plate being fixedly installed on the inner wall of the fixing frame; a photovoltaic panel, the photovoltaic panel being fixedly installed on the top of the support plate, the photovoltaic panel being a device for directly or indirectly converting solar radiation energy into electrical energy through the photoelectric effect or photochemical effect; a slide rail, the slide rail being fixedly installed on the surface of the fixing frame; a drive motor, the drive motor being slidably installed inside the slide rail; and a fixing rod, the fixing rod being fixedly installed on the surface of the drive motor. The structure includes: a drive motor for reciprocating movement of the fixed rod; a connecting rod fixedly mounted on the surface of the fixed rod; a protective cover rotatably mounted on the surface of the connecting rod for protecting the photovoltaic panel; a limiting plate fixedly mounted on the surface of the connecting rod; a sealing plate fixedly mounted on the surface of the protective cover; and a pulley rotatably mounted on the inner wall of the fixed frame. When the fixed rod moves towards the center of the fixed frame, it drives the connecting rod towards the center of the fixed frame, which in turn drives the protective cover towards the center of the fixed frame. The protective cover, upon reaching the center of the fixed frame, contacts the pulley, which then pushes the protective cover upwards.

[0007] According to the above technical solution, the limiting plate is set below the protective cover, and a torsion spring is set between the protective cover and the connecting rod. When the pulley disengages from the protective cover, the elastic force of the torsion spring will drive the protective cover to reset. The fixing frame is equipped with a protective device to prevent the photovoltaic panel from colliding and a sealing device to seal the protective cover.

[0008] According to the above technical solution, the protective device includes an L-shaped slide rod, a trapezoidal plate, a pressure plate, a fixing plate, and a sealing block. During the movement of the protective cover towards the center of the fixing frame, it contacts the trapezoidal plate, causing the protective cover to push the trapezoidal plate downwards. This downward movement of the trapezoidal plate causes the L-shaped slide rod to move downwards. The L-shaped slide rod is slidably mounted on the inner wall of the fixing frame. The trapezoidal plate is fixedly mounted on the top of the L-shaped slide rod. The pressure plate is fixedly mounted on the surface of the L-shaped slide rod. The fixing plate is fixedly mounted on the surface of the pressure plate. The sealing block is fixedly mounted on the bottom of the fixing plate and the pressure plate.

[0009] According to the above technical solution, a trapezoidal sliding plate is slidably installed on the inner wall of the fixed frame, and an L-shaped sliding plate is fixedly installed on the surface of the trapezoidal sliding plate. When the L-shaped sliding rod moves downward, it will push the trapezoidal sliding plate to move away from the L-shaped sliding rod. When the trapezoidal sliding plate moves away from the L-shaped sliding rod, it will push the L-shaped sliding plate to move away from the L-shaped sliding rod.

[0010] According to the above technical solution, a first spring is provided between the L-shaped slide bar and the fixed frame. When the trapezoidal plate disengages from the protective cover, the elastic force of the first spring will cause the L-shaped slide bar to reset. A second spring is provided between the fixed frame and the trapezoidal slide plate. When the L-shaped slide bar resets, the trapezoidal slide plate will reset under the elastic force of the second spring after losing its compression.

[0011] According to the above technical solution, the sealing device includes a connecting seat, a rotating rod, a sliding frame, and a fixed seat. When the trapezoidal sliding plate moves away from the L-shaped sliding rod, it will cause the connecting seat to move away from the L-shaped sliding rod. When the connecting seat moves away from the L-shaped sliding rod, it will push the rotating rod to rotate upward. The connecting seat is fixedly installed on the surface of the trapezoidal sliding plate. The sliding frame is slidably installed on the inner wall of the fixed frame. The fixed seat is fixedly installed at the bottom of the sliding frame. One end of the rotating rod is rotatably installed on the surface of the connecting seat, and the other end of the rotating rod is rotatably installed on the inner wall of the fixed seat.

[0012] According to the above technical solution, a groove is provided on the inner wall surface of the fixing frame, a rotating plate is rotatably installed on the inner wall of the groove, a sliding plate is slidably installed on the inner wall of the groove, and an L-shaped pull plate is fixedly installed at the bottom of the protective cover. When the rotating plate rotates downward, it will push the sliding plate to move downward. When the sliding plate moves downward, it will pull the L-shaped pull plate downward. When the L-shaped pull plate moves downward, it will pull the protective cover downward.

[0013] According to the above technical solution, a No. 3 spring is provided between the sliding frame and the fixed frame. When the trapezoidal slide plate is reset, the sliding frame will reset under the elastic force of the No. 3 spring when it loses the compression. A No. 2 torsion spring is provided between the groove and the rotating plate. When the sliding frame is reset, the rotating plate will reset under the elastic force of the No. 2 torsion spring when it loses the compression. A No. 4 spring is provided between the groove and the sliding plate. When the rotating plate is reset, the sliding plate will reset under the elastic force of the No. 4 spring when it loses the compression.

[0014] This invention provides a protection device for new energy photovoltaic panels, which has the following beneficial effects: (1) In this invention, the protective cover will contact the pulley when it moves towards the middle of the fixed frame. The pulley will push the protective cover to rotate upward. When the protective cover rotates to a horizontal state, it will cover the fixed frame. The protective cover will cover the fixed frame to prevent the photovoltaic panel from being directly damaged by hail and affecting the normal use of the equipment. At the same time, the horizontal movement of the protective cover will drive the sealing plate to move horizontally. The horizontal movement of the sealing plate towards the middle of the fixed frame will block the gap between the two protective covers, preventing rainwater or sand from entering through the gap between the protective covers, causing water damage to the equipment and affecting normal use.

[0015] (2) In this invention, the photovoltaic panel is limited by the downward movement of the pressure plate to prevent excessive vibration or wind force from affecting the installation of the equipment. At the same time, the downward movement of the pressure plate will drive the fixing plate to move downward, and the downward movement of the fixing plate will drive the sealing block to move downward. The sealing block is stuck between the photovoltaic panels by moving downward. The trapezoidal sliding plate moves away from the L-shaped sliding rod, which will push the L-shaped sliding plate to move away from the L-shaped sliding rod. The L-shaped sliding plate moves away from the L-shaped sliding rod to support the photovoltaic panel and ensure that the photovoltaic panel does not shake.

[0016] (3) The invention seals the protective cover by contacting the sliding frame, preventing rainwater and impurities from entering from all sides through gaps, thus providing protection. At the same time, the upward movement of the sliding frame will push one end of the rotating plate to rotate upward, and the upward rotation of one end of the rotating plate will drive the other end of the rotating plate to rotate downward. The downward movement of the L-shaped pull plate will drive the protective cover to pull downward. By pulling the protective cover downward, the excessive wind force will prevent the protective cover from being lifted up, causing damage to the equipment and affecting normal use.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-4 One embodiment of the present invention is: a new energy photovoltaic panel protection device, comprising: a support frame 1, which is disposed on the ground; a fixing frame 2, which is fixedly installed on the top of the support frame 1; a support plate 3, which is fixedly installed on the inner wall of the fixing frame 2; a photovoltaic panel 4, which is fixedly installed on the top of the support plate 3, and the photovoltaic panel 4 is a device for directly or indirectly converting solar radiation energy into electrical energy through photoelectric effect or photochemical effect; a slide rail 5, which is fixedly installed on the surface of the fixing frame 2; a drive motor 6, which is slidably installed inside the slide rail 5; and a fixing rod 7. The fixed rod 7 is fixedly installed on the surface of the drive motor 6; the drive motor 6 is used to drive the fixed rod 7 to move back and forth. The connecting rod 8 is fixedly installed on the surface of the fixed rod 7. The protective cover 9 is rotatably installed on the surface of the connecting rod 8 and is used to protect the photovoltaic panel 5. The limiting plate 10 is fixedly installed on the surface of the connecting rod 8. The sealing plate 11 is fixedly installed on the surface of the protective cover 9. The pulley 12 is rotatably installed on the inner wall of the fixed frame 2 to prevent rainwater or sand from entering through the gaps between the protective covers 9, which could cause water damage to the equipment and affect normal use.

[0021] The limiting plate 10 is located below the protective cover 9. A torsion spring is provided between the protective cover 9 and the connecting rod 8. When the pulley 12 disengages from the protective cover 9, the elastic force of the torsion spring will cause the protective cover 9 to reset. The fixing frame 2 is equipped with a protective device to prevent the photovoltaic panel 4 from colliding and a sealing device to seal the protective cover 9.

[0022] In this embodiment, during operation: When encountering severe weather such as heavy rain or hail, the drive motor 6 is activated. The drive motor 6 moves towards the center of the fixed frame 2. This movement of the drive motor 6 towards the center of the fixed frame 2 causes the fixed rod 7 to move towards the center of the fixed frame 2. This movement of the fixed rod 7 towards the center of the fixed frame 2 causes the connecting rod 8 to move towards the center of the fixed frame 2. This movement of the connecting rod 8 towards the center of the fixed frame 2 causes the protective cover 9 to move towards the center of the fixed frame 2. As the protective cover 9 moves towards the center of the fixed frame 2, it comes into contact with the pulley 12. The pulley 12 pushes the protective cover 9 to rotate upwards. When the protective cover 9 rotates to a horizontal position, it covers the fixed frame 2, preventing hail from directly damaging the photovoltaic panel 4 and affecting the normal use of the equipment. At the same time, the horizontal movement of the protective cover 9 causes the sealing plate 11 to move horizontally. The horizontal movement of the sealing plate 11 towards the center of the fixed frame 2 blocks the gap between the two protective covers 9, preventing rainwater or sand from entering through the gap between the protective covers 9, which could cause water damage to the equipment and affect its normal use.

[0023] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the protective device includes an L-shaped slide bar 131, a trapezoidal plate 132, a pressure plate 133, a fixing plate 134, and a sealing block 135. The L-shaped slide bar 131 is slidably installed on the inner wall of the fixing frame 2, the trapezoidal plate 132 is fixedly installed on the top of the L-shaped slide bar 131, the pressure plate 133 is fixedly installed on the surface of the L-shaped slide bar 131, the fixing plate 134 is fixedly installed on the surface of the pressure plate 133, and the sealing block 135 is fixedly installed on the bottom of the fixing plate 134 and the pressure plate 133. The downward movement of the pressure plate 133 limits the photovoltaic panel 4 to prevent excessive vibration or wind force from affecting the installation of the equipment.

[0024] A trapezoidal sliding plate 136 is slidably installed on the inner wall of the fixed frame 2. An L-shaped sliding plate 137 is fixedly installed on the surface of the trapezoidal sliding plate 136. When the L-shaped sliding plate 137 moves away from the L-shaped sliding rod 131, it will support the photovoltaic panel 4 and ensure that the photovoltaic panel 4 will not shake.

[0025] A first spring is installed between the L-shaped slide bar 131 and the fixed frame 2. When the trapezoidal plate 132 disengages from the protective cover 9, the elastic force of the first spring will cause the L-shaped slide bar 131 to return to its original position. A second spring is installed between the fixed frame 2 and the trapezoidal slide plate 136. When the L-shaped slide bar 131 returns to its original position, the trapezoidal slide plate 136 will return to its original position under the elastic force of the second spring after it loses its compression.

[0026] The sealing device includes a connecting seat 141, a rotating rod 142, a sliding frame 143, and a fixed seat 144. The connecting seat 141 is fixedly installed on the surface of the trapezoidal sliding plate 136. The sliding frame 143 is slidably installed on the inner wall of the fixed frame 2. The fixed seat 144 is fixedly installed on the bottom of the sliding frame 143. One end of the rotating rod 142 is rotatably installed on the surface of the connecting seat 141, and the other end of the rotating rod 142 is rotatably installed on the inner wall of the fixed seat 144. The sliding frame 143 contacts the protective cover 9 to form a seal, preventing rainwater and impurities from entering from all sides through gaps, thus providing a protective effect.

[0027] The inner wall surface of the fixed frame 2 is provided with a groove, a rotating plate 145 is rotatably installed on the inner wall of the groove, and a sliding plate 146 is slidably installed on the inner wall of the groove. An L-shaped pull plate 147 is fixedly installed at the bottom of the protective cover 9. By pulling the protective cover 9 downward, it is prevented from being lifted by excessive wind force, which would damage the equipment and affect normal use.

[0028] A third spring is provided between the sliding frame 143 and the fixed frame 2. When the trapezoidal slide plate 136 is reset, the sliding frame 143 will be reset under the elastic force of the third spring after the pressure is released. A second torsion spring is provided between the groove and the rotating plate 145. When the sliding frame 143 is reset, the rotating plate 145 will be reset under the elastic force of the second torsion spring after the pressure is released. A fourth spring is provided between the groove and the sliding plate 146. When the rotating plate 145 is reset, the sliding plate 146 will be reset under the elastic force of the fourth spring after the pressure is released.

[0029] In this embodiment, during operation: as the protective cover 9 moves towards the center of the fixing frame 2, it contacts the trapezoidal plate 132. The protective cover 9 pushes the trapezoidal plate 132 downward, which in turn moves the L-shaped slide rod 131 downward. The downward movement of the L-shaped slide rod 131 then moves the pressure plate 133 downward. The downward movement of the pressure plate 133 limits the photovoltaic panel 4, preventing excessive vibration or wind from affecting equipment installation. Simultaneously, the downward movement of the pressure plate 133 moves the fixing plate 134 downward, which in turn moves the sealing block 1. 35 moves downwards, and the sealing block 135 moves downwards and gets stuck between the photovoltaic panels 4. The elasticity of the sealing block 135 protects the photovoltaic panels 4. At the same time, the downward movement of the L-shaped slide bar 131 will push the trapezoidal slide plate 136 to move away from the L-shaped slide bar 131. The movement of the trapezoidal slide plate 136 away from the L-shaped slide bar 131 will push the L-shaped slide plate 137 away from the L-shaped slide bar 131. The movement of the L-shaped slide plate 137 away from the L-shaped slide bar 131 will support the photovoltaic panels 4 and ensure that the photovoltaic panels 4 do not shake.

[0030] The movement of the trapezoidal sliding plate 136 away from the L-shaped sliding rod 131 causes the connecting seat 141 to move away from the L-shaped sliding rod 131. This movement of the connecting seat 141 away from the L-shaped sliding rod 131 pushes the rotating rod 142 to rotate upwards. The upward rotation of the rotating rod 142 pushes the fixed seat 144 to slide upwards. The upward movement of the fixed seat 144 causes the sliding frame 143 to move upwards. The upward movement of the sliding frame 143 brings it into contact with the bottom of the protective cover 9, creating a seal and preventing rainwater and impurities from entering through gaps. The system provides protection from all sides. Simultaneously, the upward movement of the sliding frame 143 pushes one end of the rotating plate 145 to rotate upward. The upward rotation of one end of the rotating plate 145 causes the other end of the rotating plate 145 to rotate downward. The downward rotation of the rotating plate 145 pushes the sliding plate 146 to move downward. The downward movement of the sliding plate 146 pulls the L-shaped pull plate 147 downward. The downward movement of the L-shaped pull plate 147 causes the protective cover 9 to be pulled downward. By pulling the protective cover 9 downward, excessive wind force is prevented from lifting the protective cover 9, which could damage the equipment and affect normal use.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
