[0003] Patent publication number CN217282821U relates to a multifunctional photovoltaic power supply device, including a lifting pole, a mounting frame, and a photovoltaic panel. The mounting frame is mounted on the lifting pole, and the photovoltaic panel is mounted on the mounting frame. An electrical mounting base is mounted on the lifting pole for installing electrical appliances. A control box frame is mounted on the electrical mounting base. The control box frame contains a control box and a battery. The mounting frame is mounted on the control box frame, and the control box contains a controller and a communication module. The mounting frame includes a fixedly connected pan-tilt unit and a bracket. A longitudinal beam is mounted on the bracket, and a crossbeam is mounted on the longitudinal beam. A slot is opened on the crossbeam, and a fixing rod connected to the photovoltaic panel is installed in the slot. This invention addresses the problem that the current photovoltaic panel mounting pole structure is too simple to meet the installation needs of different electrical appliances and different types of photovoltaic panels, and that when a large number of photovoltaic panel power supply devices malfunction, timely maintenance is not possible.

[0004] The aforementioned patent addresses the problem that the current photovoltaic panel installation poles are too simple to meet the installation needs of different electrical appliances and photovoltaic panels, and that it is difficult to repair in time when there are many photovoltaic power supply devices. However, it is difficult to prevent changes in the angle of sunlight on the photovoltaic equipment caused by external force. If the angle of the photovoltaic equipment is deviated due to external force, the incident angle of sunlight will no longer be optimal, thereby reducing the power generation efficiency of the photovoltaic equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic power supply device for a floating offshore wind power monitoring system, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic power supply device for a floating offshore wind power monitoring system, comprising a placement plate and an adjustment device. A battery storage base is fixedly installed at the bottom of the placement plate, and a placement rod is fixedly installed at the top of the battery storage base. The placement rod penetrates the upper and lower walls of the placement plate, and a connecting wire is provided inside the placement rod. The photovoltaic device is connected to the battery storage base via the connecting wire. The adjustment device includes a U-shaped frame, a rotating rod, a placement frame, a photovoltaic device, an adjustment gear, a protective plate, an elastic telescopic rod, a stabilizing hole, and an inclined groove. The adjustment gear is limited by the protective plate and cannot rotate. The inability of the adjustment gear to rotate prevents the rotating rod and the placement frame from rotating. The U-shaped frame... The frame is fixedly installed on the top of the placement rod. The rotating rod rotates through the inner and outer walls of the U-shaped frame. The placement frame is fixedly installed on the circumference of the rotating rod. The photovoltaic device is fixedly installed on the top of the placement frame. The adjusting gear is fixedly installed on the circumference of the rotating rod. The protective plate is slidably installed on the circumference of the placement rod. The elastic telescopic rod is fixedly installed at the bottom of the U-shaped frame. The stabilizing hole is opened on the top of the placement plate. The inclined groove is opened on the top of the placement plate. By adjusting the angle of the photovoltaic device, it can be ensured that the photovoltaic device is always at the optimal receiving angle, increasing the amount of sunlight received. The elastic telescopic rod can effectively avoid interference from external forces, ensuring that the angle of sunlight received by the photovoltaic device will not shift due to changes in external forces, thereby improving power generation efficiency.

[0007] According to the above technical solution, the free end of the elastic telescopic rod contacts the bottom of the protective plate, and a protective spring is provided between the U-shaped frame and the protective plate, which can drive the protective plate to reset.

[0008] According to the above technical solution, the top of the protective plate is set as an arc surface. By setting the top of the protective plate as an arc surface, the protective plate can have a limiting effect on the adjusting gear. The protective plate is in contact with the adjusting gear and the protective plate is in contact with the bottom of the U-shaped frame.

[0009] According to the above technical solution, the inner wall of the stabilizing hole is provided with a load-bearing device to support the placement rod, and the bottom of the placement plate is provided with a protective device. The load-bearing device includes a stabilizing rod, a stabilizing frame, a deceleration frame, a T-shaped plate, a deceleration hole, and a support frame. The T-shaped plate resets to the left to cooperate with the support frame and contact the placement rod, restoring support for the placement rod. The stabilizing rod is fixedly installed on the inner wall of the stabilizing hole, the stabilizing frame is slidably installed on the circumferential surface of the stabilizing rod, the deceleration frame is fixedly installed on the inner wall of the inclined groove, the T-shaped plate is slidably installed on the inner wall of the deceleration frame, the deceleration hole is opened on the right side of the T-shaped plate, and the support frame is fixedly installed on the top of the placement plate. By having the T-shaped plate contact the placement rod and support it, the loosening or instability of the photovoltaic equipment caused by vibration, wind, or other external factors can be reduced, ensuring the normal operation of the photovoltaic equipment. An inspection hole is opened on the circumferential surface of the placement rod, and by having the stabilizing frame disengage from the placement rod, it is convenient to inspect the internal connecting wires of the placement rod.

[0010] According to the above technical solution, a load-bearing rod is fixedly installed on the right side of the T-shaped plate, and a load-bearing plate is fixedly installed on the right side of the load-bearing rod. A limiting plate is slidably installed on the circumferential surface of the load-bearing rod, and a limiting hole is opened on the right side of the limiting plate. Liquid is placed inside the deceleration frame, and the liquid inside the deceleration frame can only move slowly to the right side of the deceleration frame, so that the T-shaped plate can only move slowly to the right. By slowly releasing the support, the stability of the photovoltaic equipment when adjusting the angle of sunlight can be ensured. By quickly restoring the support, the loosening of the photovoltaic equipment caused by vibration, wind or other external factors can be further reduced.

[0011] According to the above technical solution, a first spring is provided between the stabilizing frame and the stabilizing hole. The first spring can drive the stabilizing frame to reset. The top of the stabilizing frame is set as an inclined surface. The bottom of the protective plate contacts the top of the stabilizing frame. The stabilizing frame contacts the T-shaped plate. A second spring is provided between the limiting plate and the load-bearing plate. The second spring can drive the limiting plate to reset. At the same time, the limiting plate is tightly attached to the right side of the T-shaped plate in the initial state.

[0012] According to the above technical solution, the protective device includes a hollow frame, an L-shaped rod, an L-shaped plate, a pressing hole, a power-off button, and a curved rod. After the L-shaped plate disengages from the T-shaped plate, it moves to the left under the elastic force of the return spring. The L-shaped plate moves to the left and contacts the pressing hole, sealing the hollow frame. The hollow frame is fixedly installed at the bottom of the placement plate, the L-shaped rod is fixedly installed at the bottom of the placement plate, and the L-shaped plate is slidably installed on the circumferential surface of the L-shaped rod. The pressing hole is located at the bottom of the hollow frame. The power-off button is fixedly installed at the bottom left side of the L-shaped plate and is electrically connected to the battery holder. The curved rod is fixedly installed at the bottom left side of the L-shaped plate. After adjustment, the L-shaped plate automatically seals the hollow frame, protecting the power-off button from sea salt spray corrosion, thereby improving the long-term reliability of the power-off button. By preventing salt accumulation from hindering the tight contact between the L-shaped plate and the pressing hole, the effectiveness of the sealing performance is ensured, further avoiding seal failure due to salt accumulation.

[0013] According to the above technical solution, a reset spring is provided between the L-shaped plate and the hollow frame. The reset spring can drive the L-shaped plate to reset. The bottom of the L-shaped plate is in contact with the pressing hole, and the L-shaped plate is in contact with the stabilizing frame.

[0014] This invention provides a photovoltaic power supply device for a floating offshore wind power monitoring system. It has the following beneficial effects: (1) The photovoltaic power supply device of the floating offshore wind power monitoring system moves away from the placement rod by the free end of the elastic telescopic rod to break away from the contact with the protective plate and release the limit on the protective plate. The elastic telescopic rod can effectively avoid interference from external forces and ensure that the angle of the photovoltaic equipment receiving light will not be shifted due to changes in external forces, thereby improving the power generation efficiency. The adjustment gear is limited by the protective plate and cannot rotate. The inability of the adjustment gear to rotate makes the rotating rod and the placement frame unable to rotate. The inability of the placement frame to rotate fixes the angle of the photovoltaic equipment receiving light. By adjusting the angle of the photovoltaic equipment, it can be ensured that the photovoltaic equipment is always at the optimal receiving angle, increasing the amount of light received, thereby maximizing light absorption and energy conversion.

[0015] (2) The photovoltaic power supply device of the floating offshore wind power monitoring system can only move slowly to the right through the T-shaped plate, so that the stabilizing frame can only move slowly to the right and disengage from the placement rod. By slowly releasing the support, the stability of the photovoltaic equipment when adjusting the angle of illumination can be ensured, thereby preventing excessive changes in the center of gravity or tilting that could cause imbalance or failure of the photovoltaic equipment. The T-shaped plate can quickly reset to the left, so that the stabilizing frame can quickly reset to the left. The T-shaped plate quickly resets to the left, and the support frame contacts the placement rod and restores the support to the placement rod. By quickly restoring the support, the loosening or instability of the photovoltaic equipment caused by vibration, wind or other external factors can be reduced, and the normal operation of the photovoltaic equipment can be maintained.

[0016] (3) The photovoltaic power supply device of the floating offshore wind power monitoring system moves to the left of the L-shaped plate to reset and contact the pressing hole and seal the hollow frame. After the adjustment is completed, the L-shaped plate automatically seals the hollow frame, which can protect the power-off button from the corrosion of sea salt spray, thereby improving the long-term reliability of the power-off button. The curved rod moves and hits the hollow frame to generate vibration. The vibration of the hollow frame shakes off the salt stains that have accumulated at the bottom. Through vibration, the sealing surface of the hollow frame can be kept clean, preventing the accumulation of salt stains from hindering the tight contact between the L-shaped plate and the pressing hole, thereby ensuring the effectiveness of the sealing performance and further avoiding the sealing failure caused by the accumulation of salt stains.

[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 1-5 One embodiment of the present invention is: a photovoltaic power supply device for a floating offshore wind power monitoring system, including a placement plate 1 and an adjustment device. A battery storage base 2 is fixedly installed at the bottom of the placement plate 1, and a placement rod 3 is fixedly installed at the top of the battery storage base 2. The placement rod 3 penetrates the upper and lower walls of the placement plate 1, and a connecting wire is provided inside the placement rod 3. A photovoltaic device 7 is connected to the battery storage base 2 through the connecting wire. The adjustment device includes a U-shaped frame 4, a rotating rod 5, a placement frame 6, the photovoltaic device 7, an adjusting gear 8, a protective plate 9, an elastic telescopic rod 10, a stabilizing hole 12, and an inclined groove 13. The adjusting gear 8 is limited by the protective plate 9 and cannot rotate. The inability of the adjusting gear 8 to rotate prevents the rotating rod 5 and the placement frame 6 from rotating. The U-shaped frame 4 is fixed. Installed on the top of the placement rod 3, the rotating rod 5 rotates through the inner and outer walls of the U-shaped frame 4. The placement frame 6 is fixedly installed on the circumferential surface of the rotating rod 5. The photovoltaic device 7 is fixedly installed on the top of the placement frame 6. The adjusting gear 8 is fixedly installed on the circumferential surface of the rotating rod 5. The protective plate 9 is slidably installed on the circumferential surface of the placement rod 3. The elastic telescopic rod 10 is fixedly installed on the bottom of the U-shaped frame 4. The stabilizing hole 12 is opened on the top of the placement plate 1. The inclined groove 13 is opened on the top of the placement plate 1. By adjusting the angle of the photovoltaic device 7, it can be ensured that the photovoltaic device 7 is always at the optimal receiving angle, increasing the amount of sunlight received. The elastic telescopic rod 10 can effectively avoid interference from external forces, ensuring that the sunlight receiving angle of the photovoltaic device 7 will not shift due to changes in external forces, thereby improving power generation efficiency.

[0021] The free end of the elastic telescopic rod 10 contacts the bottom of the protective plate 9. A protective spring 11 is provided between the U-shaped frame 4 and the protective plate 9. The protective spring 11 can drive the protective plate 9 to reset.

[0022] The top of the protective plate 9 is set as an arc surface. By setting the top of the protective plate 9 as an arc surface, the protective plate 9 can have a limiting effect on the adjusting gear 8. The protective plate 9 is in contact with the adjusting gear 8 and the bottom of the U-shaped frame 4.

[0023] In this embodiment, when it is necessary to adjust the angle of sunlight received by the photovoltaic device 7, first manually pull the free end of the elastic telescopic rod 10 away from the placement rod 3. The free end of the elastic telescopic rod 10 moves away from the placement rod 3, disengaging from the protective plate 9 and releasing the restriction on the protective plate 9. After the restriction on the protective plate 9 is released, manually pull the protective plate 9 downward. The downward movement of the protective plate 9 pulls on the protective spring 11, causing the protective spring 11 to deform and store force. At the same time, the protective plate 9 moves downward, disengaging from the adjusting gear 8 and releasing the restriction on the adjusting gear 8. After the limit of 8 is released, manually rotate the placement frame 6. The rotation of the placement frame 6 drives the photovoltaic equipment 7 to rotate to adjust the angle of illumination. After the angle of illumination of the photovoltaic equipment 7 is adjusted to a suitable position, release the protective plate 9 so that the protective plate 9 moves upward under the elastic force of the protective spring 11. The protective plate 9 moves upward under the elastic force of the protective spring 11 and contacts the adjusting gear 8 and limits the adjusting gear 8. The adjusting gear 8 cannot rotate due to the limitation of the protective plate 9. The inability of the adjusting gear 8 to rotate prevents the rotating rod 5 and the placement frame 6 from rotating. The inability of the placement frame 6 to rotate fixes the angle of illumination of the photovoltaic equipment 7.

[0024] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, a load-bearing device for supporting the placement rod 3 is provided on the inner wall of the stabilizing hole 12, and a protective device is provided at the bottom of the placement plate 1. The load-bearing device includes a stabilizing rod 141, a stabilizing frame 142, a deceleration frame 143, a T-shaped plate 144, a deceleration hole 145, and a support frame 1410. The T-shaped plate 144 resets to the left to cooperate with the support frame 1410 to contact the placement rod 3 and restore support for the placement rod 3. The stabilizing rod 141 is fixedly installed on the inner wall of the stabilizing hole 12, and the stabilizing frame 142 is slidably installed on the circumferential surface of the stabilizing rod 141. 43 is fixedly installed on the inner wall of the inclined groove 13, T-shaped plate 144 is slidably installed on the inner wall of the deceleration frame 143, deceleration hole 145 is opened on the right side of T-shaped plate 144, support frame 1410 is fixedly installed on the top of the placement plate 1, and the T-shaped plate 144 contacts the placement rod 3 and supports the placement rod 3, which can reduce the loosening or instability of photovoltaic equipment 7 caused by vibration, wind or other external factors, and maintain the subsequent normal operation of photovoltaic equipment 7. The circumferential surface of the placement rod 3 is provided with inspection holes, and the connection wires inside the placement rod 3 can be easily inspected by detaching the stabilizing frame 142 from the contact with the placement rod 3.

[0025] A load-bearing rod 146 is fixedly installed on the right side of the T-shaped plate 144, and a load-bearing plate 147 is fixedly installed on the right side of the load-bearing rod 146. A limiting plate 148 is slidably installed on the circumferential surface of the load-bearing rod 146. A limiting hole 149 is opened on the right side of the limiting plate 148. Liquid is placed inside the deceleration frame 143. The liquid inside the deceleration frame 143 can only move slowly to the right side of the deceleration frame 143, so that the T-shaped plate 144 can only move slowly to the right. By slowly releasing the support, the stability of the photovoltaic equipment 7 when adjusting the angle of sunlight can be ensured. By quickly restoring the support, the loosening of the photovoltaic equipment 7 caused by vibration, wind or other external factors can be further reduced.

[0026] A first spring is provided between the stabilizing frame 142 and the stabilizing hole 12. The first spring can drive the stabilizing frame 142 to reset. The top of the stabilizing frame 142 is set as an inclined surface. The bottom of the protective plate 9 contacts the top of the stabilizing frame 142. The stabilizing frame 142 contacts the T-shaped plate 144. A second spring is provided between the limiting plate 148 and the load-bearing plate 147. The second spring can drive the limiting plate 148 to reset, and at the same time make the limiting plate 148 tightly fit the right side of the T-shaped plate 144 in the initial state.

[0027] The protective device includes a hollow frame 151, an L-shaped rod 152, an L-shaped plate 153, a pressing hole 154, a power-off button 155, and a curved rod 156. After the L-shaped plate 153 disengages from the T-shaped plate 144, it moves to the left under the elastic force of the return spring 157 to reset. The L-shaped plate 153 moves to the left and resets to contact the pressing hole 154, sealing the hollow frame 151. The hollow frame 151 is fixedly installed at the bottom of the placement plate 1, the L-shaped rod 152 is fixedly installed at the bottom of the placement plate 1, and the L-shaped plate 153 slides on the circumferential surface of the L-shaped rod 152. The pressing hole 154 is formed in the hollow frame 151. At the bottom of 51, the power-off button 155 is fixedly installed on the left bottom of the L-shaped plate 153. The power-off button 155 is electrically connected to the battery holder 2. The curved rod 156 is fixedly installed on the left bottom of the L-shaped plate 153. After adjustment, the L-shaped plate 153 automatically seals the hollow frame 151, which can protect the power-off button 155 from sea salt spray corrosion, thereby improving the long-term reliability of the power-off button 155. By preventing salt deposits from hindering the tight contact between the L-shaped plate 153 and the pressing hole 154, the effectiveness of the sealing performance is ensured, and the sealing failure caused by salt deposits is further avoided.

[0028] A reset spring 157 is provided between the L-shaped plate 153 and the hollow frame 151. The L-shaped plate 153 can be reset by the reset spring 157. The bottom of the L-shaped plate 153 contacts the pressing hole 154 and the L-shaped plate 153 contacts the stabilizing frame 142.

[0029] In this embodiment, during operation: the protective plate 9 moves downwards to contact the stabilizing frame 142 and compresses it. The stabilizing frame 142, compressed by the protective plate 9, moves to the right, compressing the first spring. The first spring deforms and stores force under the pressure of the stabilizing frame 142. Simultaneously, the rightward movement of the stabilizing frame 142 drives the T-shaped plate 144 to move, compressing the liquid inside the deceleration frame 143. This creates a negative pressure on the right side of the deceleration frame 143, causing the limiting plate 148 to fit tightly against the right side of the T-shaped plate 144. This tight fit restricts the liquid on the left side of the deceleration frame 143 to move slowly to the right side through the limiting hole 149. This also restricts the T-shaped plate 144 to move slowly to the right, thus stabilizing the frame 14. 2 can only slowly move to the right and disengage from the placement rod 3. When the protective plate 9 moves upward and resets, disengaging from the stabilizing frame 142, the stabilizing frame 142 moves to the left and resets under the force of the first spring. The leftward movement of the stabilizing frame 142 causes the T-shaped plate 144 to move to the left. The leftward movement of the T-shaped plate 144 squeezes the liquid on the left side of the deceleration frame 143. The liquid on the left side of the deceleration frame 143 is squeezed by the T-shaped plate 144, generating negative pressure. The negative pressure on the left side of the deceleration frame 143 causes the limiting plate 148 to disengage. After the limiting plate 148 disengages from the right side of the T-shaped plate 144, the liquid inside the deceleration frame 143 can flow rapidly through the deceleration hole 145. The rapid flow of the liquid inside the deceleration frame 143 through the deceleration hole 145 allows the T-shaped plate 144 to quickly reset to the left. The rapid reset of the T-shaped plate 144 to the left allows the stabilizing frame 142 to quickly reset to the left. The rapid reset of the T-shaped plate 144 to the left cooperates with the support frame 1410 to contact the placement rod 3 and restore support for the placement rod 3.

[0030] The stabilizing frame 142 moves to the right and contacts the T-shaped plate 144, pressing it. The T-shaped plate 144, pressed by the stabilizing frame 142, moves to the right, pulling the return spring 157. The return spring 157 deforms and stores force due to the pull of the T-shaped plate 144. Simultaneously, the T-shaped plate 144 moves to the right, disengaging from the pressing hole 154 and releasing the seal on the hollow frame 151. After the seal on the hollow frame 151 is released, the power-off button 155 is manually pressed to disconnect the power to the battery holder 2. Once the power to the battery holder 2 is off, the power to the battery holder 2 and the light... When the device 7 is undergoing internal maintenance and debugging, when the T-shaped plate 144 moves to the left to reset, the T-shaped plate 144 moves to the left to disengage from the L-shaped plate 153. After the L-shaped plate 153 disengages from the T-shaped plate 144, it moves to the left to reset under the elastic force of the reset spring 157. The L-shaped plate 153 moves to the left to reset and contacts the pressing hole 154, sealing the hollow frame 151. At the same time, the L-shaped plate 153 moves to the left to reset and drives the curved rod 156 to move. The curved rod 156 moves and hits the hollow frame 151 to generate vibration. The vibration of the hollow frame 151 shakes off the salt deposits that have accumulated at the bottom.

[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.
