DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0015] See also Figure 1-4 As shown in the figure, a photovoltaic bracket that is easy to maintain provided by the present embodiment includes a bracket body 1, a photovoltaic panel 2 is fixedly installed on the top of the bracket body 1, a water pipe 3 is fixedly installed on one side of the outer wall of the bracket body 1, a valve 4 is fixedly installed inside the water pipe 3, a gear 5 is fixedly installed on one end of the valve 4 located outside the water pipe 3, and a water spraying mechanism is provided on the other side of the water pipe 3. A water tank 7 is also movably installed above the bracket body 1, and a rack 6 is fixedly connected to the side of the water tank 7 close to the water pipe 3. The gear 5 matches the rack 6 on the water tank 7. When the water tank 7 descends, the rack 6 can drive the gear 5 to rotate, thereby opening the valve 4 in the water pipe 3, so that water can be sprayed on the photovoltaic panel through the water spraying mechanism to remove dust and debris on the surface of the photovoltaic panel; when the water tank 7 rises, the rack 6 can drive the gear 5 to reverse, thereby closing the valve 4 in the water pipe 3, thereby stopping the water spraying mechanism from spraying water on the photovoltaic panel.

[0016] The inner cavity of the water tank 7 is connected with the water pipe 3 through the regulating pipe 8, and the regulating pipe 8 can be connected to the position below the valve 4 on the water pipe 3. The regulating pipe 8 is used to adjust the water flow entering the water tank 7, and then control the switching cycle of the water spraying mechanism through the valve 4. A sealing member 9 is inserted at the bottom of the water tank 7, and a stop rod is fixedly connected to the position below the water tank 7 on the bracket body 1. When the water pipe 3 injects water into the water tank 7 through the regulating pipe 8, the sealing member 9 closes the water outlet to prevent water from flowing out. When the water in the water tank 7 reaches a certain amount, the water tank 7 drops, and the bottom end of the sealing member 9 is squeezed by the stop rod and lifted up, so that the water in the water tank 7 can flow to the outside through the sealing member 9; the water tank 7 is fixedly connected to the connecting rod 10, and the connecting rod 10 is inserted into the bracket body 1. Inside, a slot is provided on one side of the connecting rod 10 in the bracket body 1, and a triangular stopper 11 is inserted in the slot. The triangular stopper 11 is slidably connected to the inside of the bracket body 1, and a first spring 12 is fixedly installed on one side of the triangular stopper 11, and the first spring 12 is fixedly installed inside the bracket body 1. A second spring 13 is fixedly installed under the connecting rod 10, and the second spring 13 is fixedly installed inside the bracket body 1; when water is filled in the water tank 7, the weight of the water tank 7 and the connecting rod 10 gradually increases, and the inclined surface of the triangular stopper 11 inserted in the connecting rod 10 is gradually stressed and pushes the triangular stopper 11 outward, and at the same time, the first spring 12 begins to shrink. When the triangular stopper 11 is completely separated from the connecting rod 10, the connecting rod 10 drops rapidly.

[0017] Further, refer to Figure 3 As shown, specifically, a third spring 23 is fixedly installed on one side of the limit plate 22, and the third spring 23 is fixedly installed on the outer wall of the water pipe 3. A groove is opened on the outer wall of the limit plate 22, and a triangular block is fixedly installed on the back of the water tank 7, and the groove matches the triangular block;

[0018] When the water tank 7 descends, it will squeeze the limit plate 22, causing the limit plate 22 to squeeze the third spring 23 to contract, and under the push of the third spring 23, the triangular block on the side wall of the water tank 7 will be engaged in the corresponding groove on the limit plate 22, so that the limit plate 22 limits the water tank 7, and then the water inside the water tank 7 is slowly discharged to below a certain weight, the second spring 13 can push the connecting rod 10 to rise, and the rising connecting rod 10 will be limited by the triangular block 11 pushed by the first spring 12 again and push the water tank 7 to rise, the limit plate 22 on the water tank 7 will be pressed open and drive the rack 6 to reverse the gear 5, so that the gear 5 drives the valve 4 to close, and the water pipe 3 is sealed, so that the water spraying mechanism stops flushing the photovoltaic panel 2. In this process, since the water in the water tank 7 is slowly discharged, the water spraying mechanism has enough time to carry out the water spraying operation.

[0019] Furthermore, the water spraying mechanism includes a hose 14 connected to the outer wall of the water pipe 3 , the hose 14 is located above the valve 4 , and the other end of the hose 14 is fixedly connected to a nozzle 15 , which is fixedly installed above the photovoltaic panel 2 .

[0020] It is understandable that, when in use, the water in the water pipe 3 is slowly injected into the water tank 7 through the regulating pipe 8, gradually increasing the weight of the water tank 7. At this time, the inclined surface of the triangular stopper 11 inserted in the connecting rod 10 is gradually stressed and pushes the triangular stopper 11 outward, and at the same time, the first spring 12 begins to shrink. When the weight of the water tank 7 accumulates to a certain extent, the triangular stopper 11 will completely separate from the connecting rod 10 and stop limiting the connecting rod 10, thereby allowing the water tank 7 to drive the connecting rod 10 to drop quickly and squeeze the second spring 13 to shrink. At the same time, the descent of the water tank 7 will drive the rack 6 and the seal 9 to drop.

[0021] When the rack 6 descends, the rack 6 drives the gear 5 to rotate, and then drives the valve 4 to rotate to open the seal of the water pipe 3, so that the water in the water pipe 3 can be discharged into the inside of the hose 14. After passing through the hose 14, the water can be sprayed out from the nozzle 15 and sprayed on the photovoltaic panel 2 to wash away the dust accumulated on the photovoltaic panel 2. In this way, the washing function of the photovoltaic panel 2 can be achieved to prevent the accumulation of dust from affecting the power generation efficiency of the photovoltaic panel 2.

[0022] At the same time, when the seal 9 drops to a certain extent, the bottom of the seal 9 will be squeezed, causing the seal 9 to be in an open state, and the water in the water tank 7 begins to be discharged through the seal 9, and the outflowing water volume is greater than the inflowing water volume.

[0023] When a certain weight of water inside the water tank 7 is discharged, the second spring 13 can push the connecting rod 10 to rise. Once the connecting rod 10 rises to a certain height, the triangular block 11 will start to limit the insertion of the connecting rod 10 again under the thrust of the first spring 12; the rise of the connecting rod 10 will cause the water tank 7 to rise, and the rise of the water tank 7 will drive the rack 6 to reverse the gear 5, so that the gear 5 drives the valve 4 to close and re-seal the water pipe 3, which further causes the nozzle 15 to stop flushing the photovoltaic panel 2.

[0024] It should be noted that in the above-mentioned setting, the key to the water spraying of the water spraying mechanism is that the weight of the water tank 7 can release the limiting effect of the triangular stopper 11, which is positively correlated with the water injection speed of the regulating pipe 8 into the water tank 7. When the water injection speed is faster, the weight of the water tank 7 increases faster, the time to release the limiting effect of the triangular stopper 11 is shorter, and the water spraying interval is shorter; when the water injection speed is slower, the water spraying interval is longer. That is, the above-mentioned setting realizes a photovoltaic bracket that is easy to maintain and can perform periodic water spraying operations on the photovoltaic panels, thereby avoiding dust and debris on the surface of the photovoltaic panels, greatly improving the effective photoelectric conversion time of the photovoltaic panels, and improving the photoelectric conversion efficiency.

[0025] Further, it should be noted that the water flow sprayed by the nozzle 15 can easily wash away the dust on the photovoltaic panel 2, but some stains may still not be washed away and slowly accumulate, which will affect the life of the photovoltaic panel 2 in the long run. Therefore, a cleaning mechanism can also be specifically designed, as shown below:

[0026] It also includes a cleaning mechanism, which includes a fan blade 16 connected inside the water pipe 3, and a reciprocating screw 17 is fixedly connected to one end of the fan blade 16 outside the water pipe 3, a slider 18 is provided on the reciprocating screw 17, and a slide bar 19 is provided on the side of the slider 18 close to the water tank 7, a shell 20 is provided at the bottom of the slide bar 19, the nozzle 15 is provided above the shell 20, and a cleaning member 21 is provided inside the shell 20.

[0027] Specifically, the water pipe 3 is rotatably connected to a fan blade 16 inside, and the fan blade 16 is located below the valve 4. The central axis of the fan blade 16 that passes through the wall of the water pipe 3 is fixedly connected to a reciprocating screw rod 17. A slider 18 is sleeved on the outer wall of the reciprocating screw rod 17. A slide bar 19 is slidably connected to the outer wall of the slider 18. A shell 20 is fixedly connected to the bottom of the slide bar 19. A nozzle 15 is fixedly installed on the shell 20. A cleaning member 21 is fixedly installed inside the shell 20. The cleaning member 21 is arranged on the top of the photovoltaic panel 2, and the cleaning member 21 is slidably connected to the photovoltaic panel 2.

[0028] It is understandable that when the valve 4 is opened to release the seal of the water pipe 3 and allow the water in the water pipe 3 to enter the interior of the hose 14, the water in the water pipe 3 will flow through and drive the fan blade 16 to rotate. The rotation of the fan blade 16 will drive the reciprocating screw 17 to rotate, and the rotation of the reciprocating screw 17 will cause the slider 18 to perform linear reciprocating motion. This reciprocating motion will cause the sliding housing 20 to move back and forth on the surface of the photovoltaic panel 2 through the slide rod 19. Further, the movement of the housing 20 will drive the cleaning member 21 to clean the surface of the photovoltaic panel 2. This helps to remove dust and debris that cannot be washed away by the water flow, thereby preventing these debris from accumulating on the surface of the photovoltaic panel 2 and affecting the power generation performance of the photovoltaic panel 2.

[0029] Furthermore, the outer wall of the reciprocating screw rod 17 is sleeved with a limit plate 22 , and the third spring 23 is sleeved with the outer wall of the reciprocating screw rod 17 .

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
