Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a water surface photovoltaic bracket. Background Art

[0002] Water surface photovoltaic technology is to install photovoltaic panels on the water surface through photovoltaic brackets to form a water surface power station. It can make rational use of land resources. The heat dissipation and mirror reflection of the water surface can increase power generation, reduce water evaporation, inhibit the reproduction of algae in the water and protect water resources.

[0003] Water surface photovoltaic technology usually requires suspending photovoltaic panels and photovoltaic brackets on the water surface. The photovoltaic brackets are formed into a square array, and multiple floats are evenly added to the bottom of the array. Anchors are installed at equal intervals on the bottom of the water around the array. The anchors are connected to the array through steel wire ropes to maintain the stability of the array. After the anchors are installed, a certain amount of steel wire rope needs to be left to ensure the overall rise and fall of the array when the water level fluctuates slightly.

[0004] However, in actual use, due to the periodic changes in the water level of the lake throughout the year, construction workers are required to regularly adjust the length of the wire rope according to the changes in the water level during the dry season or flood season. The operation process is relatively cumbersome. Secondly, large water surfaces are prone to forming waves due to the action of wind. Larger waves may cause some photovoltaic equipment to be flooded by water, causing equipment failure and affecting the use of photovoltaic equipment. For this reason, we propose a water surface photovoltaic bracket. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-9 , the present invention provides a technical solution:

[0032] Example 1:

[0033] A water surface photovoltaic support, comprising:

[0034] Frame 1, multiple mounting racks 2 are installed on the frame 1, multiple mounting racks 2 are fixedly connected to the frame 1, and the top of each mounting rack 2 is fixedly connected to a photovoltaic panel 9. The bottom of the frame 1 is evenly spaced with multiple floats 10, which are fixedly connected to the frame 1. The floats 10 provide buoyancy for the entire frame 1, the mounting racks 2, and the photovoltaic panels 9, allowing them to float on the water, making it easier to use the photovoltaic panels 9;

[0035] Anchor block 3, anchor block 3 is located at the bottom of the water, and sinks to the bottom of the water, providing a stable pulling force to the surface frame 1 through the steel wire rope 11, so that the surface photovoltaic panel 9 can maintain a stable position, thereby facilitating the use of the photovoltaic panel 9;

[0036] The adjusting component 4 is installed on the frame 1. The adjusting component 4 is provided with multiple groups. The multiple groups of adjusting components 4 pull the frame 1 together to facilitate the frame 1 to float stably on the water surface. The adjusting component 4 is connected to the anchor block 3 by a steel wire rope 11. The adjusting component 4 automatically releases or retracts the steel wire rope 11 when the water level rises or falls. The adjusting component 4 can automatically tighten or loosen the steel wire rope 11 according to the change of the water level, thereby ensuring that the frame 1 is tightened by multiple steel wire ropes 11 while keeping the frame 1 from being flooded by water, thereby facilitating the use of the photovoltaic panel 9.

[0037] The adjusting assembly 4 includes a rail 41 installed on the frame 1, the rail 41 is fixedly connected to the frame 1, a sliding frame 42 is provided in the rail 41, the sliding frame 42 is slidably connected to the rail 41, a winding mechanism 5 and a driving mechanism 6 are provided on the sliding frame 42, the driving mechanism 6 drives the winding mechanism 5 to reel and unwind the wire rope 11, a trigger mechanism 7 is provided between the rail 41 and the driving mechanism 6, and the trigger mechanism 7 switches the rotation direction of the driving mechanism 6 when it is squeezed by the driving mechanism 6, and a switching mechanism 8 for limiting the unwinding mechanism is provided on one side of the sliding frame 42.

[0038] The winding mechanism 5 includes a drum 51 installed on the sliding frame 42, and the wire rope 11 is wound on the drum 51. Both sides of the drum 51 are rotatably connected to the sliding frame 42, and one side of the drum 51 is connected to the driving mechanism 6. The drum 51 can wind up the wire rope 11, so that the frame 1 can automatically adjust the tension of the wire rope 11 on the frame 1 according to the water level.

[0039] The driving mechanism 6 includes a motor 61 mounted on the sliding frame 42 . The motor 61 is fixedly connected to the sliding frame 42 . The free end of the output shaft of the motor 61 is fixedly connected to the rotating shaft 52 of the reel 51 .

[0040] The trigger mechanism 7 includes a pressure sensor 1 71 and a pressure sensor 2 72 installed on the track 41. The pressure sensor 1 71 and the pressure sensor 2 72 are both fixedly connected to the track 41, and the pressure sensor 1 71 and the pressure sensor 2 72 are symmetrically distributed about the motor 61. The pressure sensor 1 71 controls the rotation of the motor 61 and causes the reel 51 to unwind. The pressure sensor 2 72 controls the reverse rotation of the motor 61 and causes the reel 51 to rewind. A spring 1 73 is provided between the sliding frame 42 and the track 41. The spring 1 73 is in a stretched state. The stretching force of the spring 1 73 is the same as the tensioning force of the wire rope 11, so that the sliding frame 42 is in a position between the pressure sensor 1 71 and the pressure sensor 2 72, ensuring that the motor 61 is in a non-rotating state when the normal water level does not change, so that the frame 1 can maintain a stable state.

[0041] The switching mechanism 8 includes a latch 81 mounted on the sliding frame 42, and a plurality of sockets 82 that are compatible with the latch 81 are provided on the surface of the reel 51. An electromagnet 83 is fixedly connected to the bottom of the latch 81, and the electromagnet 83 is slidably connected to the sliding frame 42. The bottom of the latch 81 is slidably connected to the sliding frame 42. A spring 2 85 is provided between the electromagnet 83 and the sliding frame 42, and the two ends of the spring 2 85 are fixedly connected to the latch 81 and the sliding frame 42 respectively. An iron block 86 is provided on the sliding frame 42, and the iron block 86 is fixedly connected to the sliding frame 42. When the electromagnet 83 is energized, it is attracted to the surface of the iron block 86.

[0042] A roller 53 is provided on one side of the sliding frame 42 to support the wire rope 11. The roller 53 is rotatably connected to the sliding frame 42. The roller 53 conveniently guides the movement direction of the wire rope 11, reduces the possibility of friction between the wire rope 11 and the frame 1, and extends the service life of the wire rope 11.

[0043] The frame 1 is floated on the water surface by the buoy 10, and the anchor block 3 positions the frame 1 by pulling the wire rope 11. When the water level rises, the wire rope 11 will tighten the drum 51, and the pulling force of the drum 51 will act on the sliding frame 42. After the sliding frame 42 is pulled, it will pull the spring 1 73. The spring 1 73 is stretched, and the sliding frame 42 contacts the pressure sensor 1 71. Multiple pressure sensors 1 71 are simultaneously subjected to pressure. At this time, the electromagnet 83 is attracted to the surface of the iron block 86, the spring 2 85 is stretched, the pin 81 will be separated from the drum 51, and the motor 61 rotates at the same time to drive the drum 51 to release the wire rope 11. When the sliding frame 42 gradually separates from the pressure sensor 1 71 under the action of the spring 1 73, the motor 61 rotates at the same time. 61 stops rotating, the electromagnet 83 loses its magnetic force, the second spring 85 pulls the electromagnet 83 and the latch 81 into the drum 51, the wire rope 11 is extended, and the entire frame 1 rises under the action of the buoy 10, which can ensure that the frame 1 is pulled more stably and that the frame 1 is above the water surface. When the water level drops, the spring 1 73 pulls the sliding frame 42 to fit the second pressure sensor 72, and the electromagnet 83 is energized at the same time. The electromagnet 83 is attracted to the iron block 86 and pulls the second spring 85 at the same time. The motor 61 rotates in the opposite direction, driving the wire rope 11 to tighten until the sliding frame 42 is separated from the second pressure sensor 72, the electromagnet 83 loses its magnetic force, and the second spring 85 drives the electromagnet 83 to be reinserted into the drum 51.

[0044] In the case of small waves, the wire rope 11 does not directly contact the pressure sensor 1 71 and the pressure sensor 2 72 when pulled and moved, and thus the electromagnet 83 and the motor 61 are not activated. Therefore, the spring 1 73 provides a certain margin for the frame 1 in small waves, and small waves are not likely to splash and flow into the photovoltaic panel 9 device, thereby reducing the energy loss caused by the continuous activation of the motor 61 due to frequent adjustments;

[0045] In strong winds and waves that may flood into the photovoltaic panel 9 equipment, the wind and waves are large and the width of the wind and waves is also wide. When the crest of the wind and waves moves to the bottom of the frame 1, the entire frame 1 receives an upward lifting force, and the motor 61 and the electromagnet 83 are started to release the wire rope 11. When the trough of the wind and waves moves to the bottom of the frame 1, the entire frame 1 will drop, and the stability of the frame 1 will decrease, and then the motor 61 and the electromagnet 83 will be started to tighten the wire rope 11, thereby maintaining the stability of the frame 1.

[0046] According to the above embodiment, embodiment 2,

[0047] A sleeve 87 is provided on the outside of the rotating shaft 52, and the sleeve 87 is slidably connected to the rotating shaft 52. A plurality of connecting grooves 88 are provided on the outside of the rotating shaft 52, and a plurality of connecting grooves 89 corresponding to the connecting grooves 88 are provided on the free end of the output shaft of the motor 61. A plurality of protrusions 80 are fixedly connected to the inside of the sleeve 87, and the plurality of protrusions 80 correspond to the connecting grooves 88 one by one. The sleeve 87 is rotatably connected to the latch 81. When there is wind and waves or the water level rises and falls, the electromagnet 83 will directly attract the iron block 86, thereby separating the latch 81 from the reel 51. At the same time, the sleeve 87 is released from the rotating shaft 51. 2 is connected to the output shaft of the motor 61, and then the motor 61 drives the reel 51 to rewind and unwind after it is started. By separating the output shaft of the motor 61 from the rotating shaft 52 of the reel 51, it is ensured that when the switching mechanism 8 is not separated from the rotating shaft 52, the motor 61 will not drive the reel 51 to rotate. When the electromagnet 83 and the iron block 86 are attracted, the sleeve 87 is inserted into the outside of the output shaft of the motor 61 to connect the motor 61 and the reel 51 to each other, so that the motor 61 can transmit a stable output force, reducing the possibility of the motor 61 being limited by the latch 81 when driving the reel 51 to rotate and then burning.

[0048] According to the above embodiment, embodiment three,

[0049] A push ring 12 is fixedly connected to the outside of the output shaft of the motor 61, and a plurality of push rods 13 are fixedly connected to the push ring 12. A knocking rod 14 is rotatably connected to the side of the frame 1, and the end of the knocking rod 14 is fixedly connected to the knocking head 15. The knocking head 15 is fitted with the buoy 10. A spring three 16 is provided between the knocking rod 14 and the frame 1, and the two ends of the spring two 85 are fixedly connected to the frame 1 and the knocking rod 14 respectively. When the wire rope 11 is pulled, that is, when there are wind and waves, the animals and plants in the water will float on the water surface, thereby attracting birds to come for food, and when the wind and waves are large, the birds need a resting place, and the birds are more likely to land on the photovoltaic panel 9 to rest. Then, when there is wind and waves, the wire rope 11 pulls the sliding frame 42 to move, the motor 61 will rotate, and the motor 61 drives the push ring 12 and the push rod 13 to rotate. The push rod 13 will drive the knocking rod 14 to swing, and the knocking rod 14 will knock on the buoy 10, thereby generating sound waves, and the irregular sound waves will disperse Birds, thereby reducing the possibility of bird droppings falling on the photovoltaic panel 9. In addition, since the photovoltaic equipment will generate temperature when working, birds like to build nests between the photovoltaic rack and the frame 1, which may easily lead to insufficient heat dissipation of the photovoltaic equipment and thus damage the photovoltaic equipment. When the water level rises, the habitat of birds is submerged, and it is also easy for them to build nests or rest between the frame 1 and the photovoltaic panel 9, which may easily lead to bird droppings adhering to the surface of the photovoltaic panel 9, causing the photovoltaic panel 9 to malfunction. When the water level drops, aquatic organisms are exposed in shallow water areas, attracting birds to come for food. Birds are likely to rest at the position of the photovoltaic panel 9, and their droppings may easily damage the photovoltaic panel 9. The rise and fall of water levels and wind and waves will cause the knocking rod 14 to rotate, and the knocking rod 14 will generate irregular sound waves to disperse birds, reducing the possibility of bird droppings falling on the photovoltaic panel 9. Birds are dispersed by sound waves and are not easy to build nests between the photovoltaic panel 9 and the frame 1, thereby ensuring the safety of the use of the photovoltaic panel 9.
