In the initial state, the adjusting water tank 10 is filled with water, and both ends of the adjusting bracket 3 are installed with one-way locking structures for limiting the one-way sliding of the fixed tensioning cable 6 and the adjusting tensioning cable 7. The one-way locking structure is used to make the fixed weight 9 and the adjusting water tank 10 tension the fixed tensioning cable 6 and the adjusting tensioning cable 7 respectively, and prevent the tensioning cable 6 and the adjusting tensioning cable 7 between the two supporting structures 1 from being loosened under the gravity of the photovoltaic panel 8; A fixed shell 11 is fixedly installed inside the two supporting structures 1, and a limiting ring for limiting the regulating water tank 10 is fixedly installed on the fixed shell 11. The regulating water tank 10 is located inside the limiting ring. The limiting ring is used to prevent the regulating water tank 10 from shaking due to wind. A water outlet tank 12 is fixedly installed inside the fixed shell 11. A water injection hole 13 for injecting water into the regulating water tank 10 is opened on one side of the water outlet tank 12. A water discharge control structure is arranged on the water injection hole 13, and a water outlet structure is arranged at the bottom of the regulating water tank.

[0023] The rotation limiting structure includes a driving shaft 14 rotatably connected to the supporting top plate 2, one end of the windward plate 5 is rotatably connected to one end of the driving shaft 14, and the other end of the driving shaft 14 is fixedly connected to a control cam 15, and a control groove 16 is provided inside the control cam 15, and the control groove 16 is composed of a sliding groove 16-1 and two guide grooves 16-2 provided at both ends of the sliding groove 16-1; A control plate 17 is slidably connected to the lower end of the support top plate 2, and a sliding groove is provided at the lower end of the support top plate 2. The control plate 17 can only slide up and down inside the sliding groove. A control guide shaft 18 matching the control groove 16 is fixedly connected to the side of the control plate 17 close to the control cam 15. A support locking plate 19 is slidably connected to the control plate 17. A support locking spring 20 is installed between the control plate 17 and the support locking plate 19. A self-locking roller 21 is rotatably connected to the support locking plate 19. One end of a support connecting rod 22 is rotatably connected to the adjustment bracket 3, and a support slider 23 is rotatably connected to the other end of the support connecting rod 22. A support self-locking block 24 matching the self-locking roller 21 is fixedly connected to the lower end of the support slider 23. The cross-section of the support self-locking block 24 is set to a right-angled trapezoid. In the initial state, the support locking plate 19 is pushed in the direction close to the support self-locking block 24 under the action of the support locking spring 20; An adjusting self-locking card plate 27 is rotatably connected to the support top plate 2, and a triangular block 28 is fixedly connected to the upper end of the adjusting self-locking card plate 27. A supporting spring 29 is installed between the adjusting self-locking card plate 27 and the support top plate 2. In the initial state, the adjusting self-locking card plate 27 is pushed to maintain a vertical state under the action of the supporting spring 29. A control guide block 30 that cooperates with the adjusting self-locking card plate 27 is fixedly connected to the control plate 17. The cross-section of the control guide block 30 is set to be triangular. An adjusting locking roller 31 that cooperates with the block 28 is rotatably connected to the adjusting bracket 3.

[0024] In the initial state, in a windless environment, the windward plate 5 maintains a vertical state under the action of gravity. At this time, the guide shaft 18 is located inside the sliding groove 16-1, and the control plate 17 is located at the highest point. Under the action of the angle adjustment spring 4, the adjustment bracket 3 is pulled to keep the adjustment bracket 3 and the support top plate 2 in an inclined state. The adjustment bracket 3 pulls the support slider 23 to slide on the support top plate 2 through the support connecting rod 22. After the inclined surface of the support self-locking block 24 contacts the self-locking roller 21, the support self-locking block 24 pushes the self-locking roller 21 downward, and the support locking plate 19 compresses the support locking spring 20 downward until the support self-locking block 24 passes the position of the self-locking roller 21. After the straight edge of the support self-locking block 24 contacts the self-locking roller 21, the self-locking roller 21 limits the support self-locking block 24 to the current position; In a windy environment, the windward plate 5 swings under the action of wind, and the windward plate 5 drives the drive shaft 14 to rotate, and the drive shaft 14 drives the control cam 15 to rotate, so that the guide shaft 18 enters the guide groove 16-2, and pulls the control plate 17 downward through the guide groove 16-2 to slide downward, so that the support locking plate 19 slides downward, and the self-locking roller 21 and the support self-locking block 24 are separated. At this time, under the action of the gravity of the adjusting water tank 10, the adjusting bracket 3 is pulled downward to swing, and the angle adjustment spring 4 is compressed, so that the adjusting bracket 3 and the supporting top plate 2 are fitted together. The photovoltaic panel is in a horizontal state at this time, reducing the windward surface and thus reducing the impact of wind on the photovoltaic panel, thereby realizing protection of the photovoltaic flexible bracket; when the adjusting water tank 10 slides downward to the extreme position, the water inside the adjusting water tank 10 flows out, thereby reducing the gravity of the adjusting water tank 10.

[0025] When the adjustment bracket 3 and the supporting top plate 2 are fitted together, the adjustment locking roller 31 contacts the inclined surface of the block 28, and the block 28 pushes the adjustment self-locking card plate 27 to rotate, thereby compressing the support spring 29, until the adjustment locking roller 31 slides past the block 28, and the adjustment self-locking card plate 27 is pushed back to its original position under the action of the support spring 29, and the straight-faced card column adjustment locking roller 31 of the block 28 restricts the adjustment bracket 3 to the current position through the adjustment locking roller 31; When the wind stops, the windward plate 5 returns to the vertical state under the action of gravity, the guide shaft 18 is located inside the sliding groove 16-1, and the control plate 17 is at the highest point. At this time, the inclined surface of the control guide block 30 is contacted with the adjusting self-locking card plate 27, and then the control guide block 30 pushes the adjusting self-locking card plate 27 to swing, so that the card block 28 and the adjusting locking roller 31 are disengaged, and the adjusting bracket 3 is pulled under the action of the angle adjustment spring 4 to keep the adjusting bracket 3 and the supporting top plate 2 in an inclined state, and the adjusting bracket 3 pulls the empty adjusting water tank 10 upward until the adjusting water tank 10 is pulled to the position of the water injection hole 13, and the water inside the outlet water tank 12 flows into the adjusting water tank 10 through the water injection hole 13.

[0026] An arc-shaped slot is formed on one side of the clamping block 28 close to the self-locking clamping plate, so as to facilitate the fitting of the arc-shaped slot and the adjustment locking roller 31 .

[0027] An air buffer chamber 33 is fixedly connected to the lower end of the support top plate 2. A semicircular air chamber 34 is provided inside the air buffer chamber 33. The drive shaft 14 is rotatably connected inside the air chamber 34. A push plate 36 is fixedly connected to the drive shaft 14. In the initial state, when the windward plate 5 is in a vertical state, the push plate 36 remains vertical, and the push plate 36 is located in the middle of the semicircular air chamber 34. Two air outlets 37 are provided inside the air chamber 34, and the air outlets 37 are respectively provided at both ends of the air chamber 34. When the wind blows, the windward plate 5 rotates, and the windward plate 5 drives the push plate 36 to rotate. When the push plate 36 rotates inside the air chamber 34, the push plate 36 rotates toward one of the air outlets 37, thereby compressing the air inside the air chamber 34. The air inside the air chamber 34 is slowly discharged through this air outlet 37, and the external air slowly enters the air chamber 34 through the other air outlet 37, thereby reducing the swing of the adjustment bracket 3 due to sudden gusts of wind, thereby affecting the working efficiency of the device. When encountering continuous strong winds, the continuous wind force pushes the windward plate 5 to swing to a predetermined position, thereby controlling the swing of the adjustment bracket 3.

[0028] A counterweight block 38 is fixedly connected to the lower end of the windward plate 5 so that the windward plate 5 remains in a vertical state.

[0029] The water outlet structure includes a water outlet hole 39 opened at the bottom of the regulating water tank 10, a sealing plug 40 is slidably connected inside the water outlet hole 39, and a sealing spring 41 is connected between the sealing plug 40 and the regulating water tank 10. In the initial state, the sealing plug 40 is pulled to be located inside the water outlet hole 39 under the action of the sealing spring 41, thereby blocking the water outlet hole 39 to prevent the water inside the regulating water tank 10 from flowing out. A support platform 42 is fixedly installed on the fixed housing 11, and a sealing plug is fixedly connected to the support platform 42. A control water outlet pipe 43 cooperates with 40, and a plurality of drain holes 44 are opened on the control water outlet pipe 43. When the regulating water tank 10 slides downward to the extreme position, the control water outlet pipe 43 is inserted into the water outlet hole 39, so that the sealing plug 40 is pushed upward by the control water outlet pipe 43, so that the sealing plug 40 is pushed out from the water outlet hole 39, and the water inside the regulating water tank 10 flows into the drain hole 44 through the water outlet hole 39 and the control water outlet pipe 43, thereby realizing the draining operation of the regulating water tank 10.

[0030] The water discharge control structure includes a cover plate 45 slidably connected to the fixed housing 11, and a shielding spring 46 is installed between the cover plate 45 and the fixed housing 11. The cover plate 45 is used to shield the water injection hole 13. In the initial state, the shielding spring 46 pushes the cover plate 45 to slide downward until the cover plate 45 shields the water injection hole 13. At this time, the water in the water outlet tank 12 cannot flow out through the water injection hole 13; Both ends of the adjusting tensioning cable 7 are fixedly connected to a supporting shell 47, the adjusting water tank 10 is slidably connected inside the supporting shell 47, a compression spring 48 is installed between the supporting shell 47 and the adjusting water tank 10, in the initial state, the compression spring 48 pushes the adjusting water tank 10 upward, and the upper end of the adjusting water tank 10 is fixedly connected to a pushing matching plate 49 that matches the cover plate 45; During use, when the adjusting bracket 3 rotates upward, the adjusting tensioning cable 7 drives the supporting shell 47 to move upward to the extreme position. At this time, the pushing matching plate 49 on the adjusting water tank 10 pushes the covering plate 45 to slide upward. At this time, water flows into the adjusting water tank 10 through the water injection hole 13. After the water enters the adjusting water tank 10, the gravity of the adjusting water tank 10 increases, thereby compressing the compression spring 48 downward until the shielding spring 46 pushes the covering plate 45 to shield the water injection hole 13 and stops water injection.

[0031] A water tank 50 is fixedly installed at the bottom of the fixed shell 11, and the control water outlet pipe 43 is connected to the inside of the water tank 50 through a pipeline. When the regulating water tank 10 slides downward to the extreme position, the water inside the regulating water tank 10 enters the water tank 50 through the control water outlet pipe 43. The water tank 50 is located below the outlet tank 12. The water tank 50 is connected to the water inlet of the water pump 51 through a pipeline. The water outlet of the water pump 51 is connected to the outlet tank 12 through a pipeline. A water level detection device is installed inside the outlet tank 12. When the water level inside the outlet tank 12 is low, the water pump 51 is started to pump the water inside the water tank 50 into the outlet tank 12, and this cycle is repeated to save water resources.

[0032] The one-way locking structure includes conical holes 52 opened at both ends of the adjusting bracket 3, the end with a smaller diameter of the conical hole 52 is close to the photovoltaic panel 8, and one-way clamping blocks are installed at both ends of the fixed tensioning cable 6 and the adjusting tensioning cable 7. The one-way clamping block is composed of two semi-conical one-way limit blocks 53, and a tensioning spring 54 is connected between the two one-way limit blocks 53. A one-way locking spring 55 is installed between the adjusting bracket 3 and the one-way clamping block. In the initial state, the tensioning spring 54 pushes the two one-way limit blocks 53 in a direction close to each other, thereby pressing the two one-way limit blocks 53 onto the fixed tensioning cable 6 and the adjusting tensioning cable 7, and the one-way locking spring 55 pushes the one-way limit block 53 in a direction close to the conical hole 52; A plurality of inverted teeth 56 with a right-angled triangle cross section are fixedly connected to the inner side of the one-way limit block 53, so as to achieve the compression and fixing of the tensioning cable 6 and the adjustment of the tensioning cable 7; When in use, the one-way limit block 53 is installed on the fixed tensioning cable 6 and the adjusting tensioning cable 7, and the tensioning spring 54 pushes the two one-way limit blocks 53 in the direction of approaching each other, and the one-way locking spring 55 pushes the one-way limit block 53 in the direction of approaching the conical hole 52. The conical surface of the one-way limit block 53 is stuck in the conical hole 52. Under the action of gravity of the photovoltaic panel 8, the two ends of the fixed tensioning cable 6 and the adjusting tensioning cable 7 are pulled in the direction close to the photovoltaic panel 8. At this time, the inverted teeth 56 press the fixed tensioning cable 6 and the adjusting tensioning cable 7, and the fixed tensioning cable 6 and the adjusting tensioning cable 7 are pulled. The movable one-way limit block 53 slides synchronously in the direction close to the tapered hole 52, so that under the action of gravity, the two one-way limit blocks 53 press the fixed tensioning cable 6 and the adjusting tensioning cable 7, thereby fixing the two ends of the fixed tensioning cable 6 and the adjusting tensioning cable 7; when the tension of the fixed tensioning cable 6 and the adjusting tensioning cable 7 is relaxed, the one-way limit block 53 is pulled to slide in the direction away from the tapered hole 52 under the action of the fixed weight 9 and the adjusting water tank 10, and the one-way limit block 53 is pushed to slide in the direction close to the tapered hole 52 by the one-way locking spring 55 until the limit block 53 is pushed into the tapered hole 52.

[0033] When implementing: In the initial state, in a windless environment, the windward plate 5 maintains a vertical state under the action of gravity. At this time, the guide shaft 18 is located inside the sliding groove 16-1, and the control plate 17 is located at the highest point. Under the action of the angle adjustment spring 4, the adjustment bracket 3 is pulled to keep the adjustment bracket 3 and the support top plate 2 in an inclined state. The adjustment bracket 3 pulls the support slider 23 to slide on the support top plate 2 through the support connecting rod 22. After the inclined surface of the support self-locking block 24 contacts the self-locking roller 21, the support self-locking block 24 pushes the self-locking roller 21 downward, and the support locking plate 19 compresses the support locking spring 20 downward until the support self-locking block 24 passes the position of the self-locking roller 21. The straight edge of the support self-locking block 24 contacts the self-locking roller 21, and the self-locking roller 21 limits the support self-locking block 24 to the current position; In a strong wind environment, the windward plate 5 swings under the action of wind force, and the windward plate 5 drives the driving shaft 14 to rotate, and the driving shaft 14 drives the control cam 15 to rotate, so that the guide shaft 18 enters the guide groove 16-2, and the control plate 17 is pulled downward through the guide groove 16-2 to slide downward, so that the support locking plate 19 slides downward, and the self-locking roller 21 and the support self-locking block 24 are separated. At this time, under the action of the gravity of the adjustment water tank 10, the adjustment bracket 3 is pulled downward to swing, and the angle adjustment spring 4 is compressed, so that the adjustment bracket 3 and the support top plate 2 are fitted together. The photovoltaic panel is in a horizontal state at this time, reducing the windward surface and thus reducing the impact of wind force on the photovoltaic panel, thereby realizing protection of the photovoltaic flexible bracket; When the regulating water tank 10 slides downward to the extreme position, the control water outlet pipe 43 is inserted into the water outlet hole 39, so that the sealing plug 40 is pushed upward by the control water outlet pipe 43, so that the sealing plug 40 is pushed out from the water outlet hole 39, and the water inside the regulating water tank 10 flows into the drain hole 44 through the water outlet hole 39 and the control water outlet pipe 43, and then enters into the water storage tank 50, thereby reducing the gravity of the regulating water tank 10.

[0034] When the adjustment bracket 3 and the supporting top plate 2 are fitted together, the adjustment locking roller 31 contacts the inclined surface of the block 28, and the block 28 pushes the adjustment self-locking card plate 27 to rotate, thereby compressing the support spring 29, until the adjustment locking roller 31 slides past the block 28, and the adjustment self-locking card plate 27 is pushed back to its original position under the action of the support spring 29, and the straight-faced card column adjustment locking roller 31 of the block 28 restricts the adjustment bracket 3 to the current position through the adjustment locking roller 31; When the wind stops, the windward plate 5 returns to the vertical state under the action of gravity, the guide shaft 18 is located inside the sliding groove 16-1, and the control plate 17 is located at the highest point. At this time, the inclined surface of the control guide block 30 is contacted with the adjustment self-locking card plate 27, and then the control guide block 30 pushes the adjustment self-locking card plate 27 to swing, so that the card block 28 and the adjustment locking roller 31 are disengaged, and the adjustment bracket 3 is pulled under the action of the angle adjustment spring 4, so that the adjustment bracket 3 and the supporting top plate 2 are kept in an inclined state, and the adjustment bracket 3 pulls the empty adjustment water tank 10 upward; The adjusting tensioning cable 7 drives the supporting shell 47 to move upward to the extreme position. At this time, the pushing matching plate 49 on the adjusting water tank 10 pushes the covering plate 45 to slide upward. At this time, water flows into the adjusting water tank 10 through the water injection hole 13. After the water enters the adjusting water tank 10, the gravity of the adjusting water tank 10 increases, thereby compressing the compression spring 48 downward until the shielding spring 46 pushes the covering plate 45 to shield the water injection hole 13 and then stops water injection.
