Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, in particular to a photovoltaic equipment with adjustable inclination angle. Background Art

[0002] Photovoltaic power generation is a technology that converts sunlight directly into electrical energy through photovoltaic cells. Photovoltaic cells are usually made of semiconductor materials and can generate electric current when they receive sunlight. The efficiency of the photovoltaic system depends on the incident angle of sunlight, which varies with time and season.

[0003] Patent announcement number CN221614885U discloses a photovoltaic device support with adjustable tilt angle, including a support body, an adjustment box fixedly connected to the bottom of the inner side of the support body, a motor fixedly installed on the left side of the inner cavity of the adjustment box, a first rotating rod fixedly connected to the output end of the motor, a main gear fixedly connected to one side of the first rotating rod, a sub-gear engaged with the surface of the main gear, a second rotating rod fixedly connected to the inner cavity of the sub-gear, a supporting plate fixedly connected to the top of the second rotating rod, and an L-shaped plate fixedly connected to the top of the supporting plate. This patent solves the problem that the existing support can adjust the tilt angle but does not have the function of rotation and cannot be adjusted according to the direction of sunlight, which greatly reduces the efficiency of converting solar energy into electrical energy and reduces the practicality of the device through the arrangement of the motor, the first rotating rod, the main gear, the sub-gear, the second rotating rod and the supporting plate.

[0004] However, when the tilt-adjustable photovoltaic equipment is working, the following problems still exist: when the photovoltaic panel is tilting, the motor may malfunction, causing the push rod to stop moving. Under the action of gravity, the photovoltaic panel will quickly flip to a horizontal position. At the same time, the photovoltaic panel will collide with the base frame, causing damage to the photovoltaic panel and affecting its normal use. Summary of the Invention

[0017] (3) In this invention, when the arc plate rotates, the protrusion on the arc plate will contact the switch, so that the motor will drive the roller to roll to clean the dust on the surface of the photovoltaic panel, preventing excessive accumulation of dust on the surface of the photovoltaic panel and affecting the use of the photovoltaic panel.

When the electric push rod device 5 fails, the support plate 301 flips downward quickly to push the hydraulic rod 602 in the hydraulic cylinder 603. The limit block 609 at the bottom of the hydraulic rod 602 will limit the T-shaped block 610, reducing the flow speed of the liquid between the hydraulic cylinder 603 and the oil cylinder 606, thereby slowing down the speed.

[0029] The top of the T-shaped block 610 is set as an inclined surface, and the limit block 609 contacts the top inclined surface of the T-shaped block 610. A spring is set between the left side of the T-shaped block 610 and the inner wall of the hydraulic cylinder 603.

[0031] The top of the triangular rod 304 is set as a slope. When the photovoltaic panel is installed, the top slope of the triangular rod 304 is in contact. A No. 1 spring clip is set between the lower pressure rod 306 and the U-shaped plate 309, and a No. 2 spring clip is set on the left side of the triangular rod 304, so that during the abnormal disassembly process of the photovoltaic panel, the insulating sheet 307 can be separated from the alarm 305 through the No. 2 spring clip.

[0032] The cleaning device includes a motor 701, a roller 702, a nozzle 703, a support plate 704, a conduit 705, a water tank 706, two baffles 707, a baffle tube 708, two U-shaped rods 712, a gear 713, a rack 714, a support frame 715 and a rotating rod 716. The support frame 715 is slidably mounted on the right side of the support plate 301, the motor 701 is fixedly mounted on the top of the support frame 715, the switch 7 is electrically connected to the motor 701, the rotating rod 716 is fixedly mounted on the output end of the motor 701, the gear 713 is fixedly mounted on the circumferential surface of the rotating rod 716, and the rack 714 is fixedly mounted on the Internally, the gear 713 is meshed with the rack 714, the roller 702 is fixedly mounted on the circumferential surface of the rotating rod 716, the nozzle 703 is fixedly mounted in the surface groove of the roller 702, the support plate 704 is fixedly mounted on the left side of the support plate 301, the conduit 705 is fixedly mounted on the top of the support plate 704, the water tank 706 is fixedly mounted on the top of the conduit 705, the two baffle rods 707 are fixedly mounted on the top of the support plate 704, the baffle pipe 708 is fixedly mounted on the bottom of the water tank 706, the two U-shaped rods 712 are fixedly mounted on the top of the support plate 301, and the roller 702 and the conduit 705 are connected through a water pipe.

[0033] The two baffles 707 are fixedly installed on the top of the support plate 704. There is a rotating rod 716 between the two baffles 707. The rotating rod 716 is in contact with the two baffles 707. When the rotating rod 716 moves, it drives the two baffles 707 to slide, so that the two baffles 707 drive the support plate 704 to slide on the left side of the clamping device 3.

[0034] The cleaning device also includes a baffle 709, a curved plate 710 and a square rod 711. The baffle 709 is fixedly mounted on the top of the inner wall of the baffle tube 708. The curved plate 710 is fixedly mounted on the end of the rotating rod 716 close to the water tank 706. The square rod 711 slides through the interior of the baffle tube 708. The square rod 711 is fixedly connected to the curved plate 710. When the rotating rod 712 rotates, the curved plate 710 will intermittently collide with the square rod 711 in the baffle tube 708, causing the baffle 709 to open intermittently. The drum 702 will drive the nozzle 703 inside it to intermittently spray water on the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel.

[0035] One end of the square rod 711 is set to an arc surface, and the square rod 711 contacts the arc surface of the arc plate 710. A No. 3 spring is set between the inner wall of the retaining tube 708 and the baffle 709. There are several protrusions on the surface of the arc plate 6. When the arc plate 6 rotates, the protrusions contact the switch 7. Since the switch 7 is electrically connected to the motor 701, the motor 701 runs when flipping.

[0036] When working: When the electric push rod device 5 is in operation, it will push the flip frame 2 to flip upwards. When the flip frame 2 flips, it will drive the support plate 301 to flip. When the support plate 301 flips, it will drive the photovoltaic panel to flip. When the electric push rod device 5 fails, the photovoltaic panel will flip downwards under the action of gravity. When the photovoltaic panel flips, it will drive the support plate 301 to flip. When the support plate 301 flips, it will drive the flip frame 2 to flip. When the flip frame 2 flips, it will drive the fixed block 601 to move downward. When the fixed block 601 moves downward, it will push the hydraulic rod 602 to move downward. When the hydraulic rod 602 moves downward, it will push the piston plate 604 to When the piston plate 604 moves downward, the liquid in the hydraulic cylinder 603 enters the oil cylinder 606 through the hydraulic pipe. When the liquid enters the oil cylinder 606, it pushes the lower pressure plate 607 to move downward. When the lower pressure plate 607 moves downward, it pushes the spring 608 to move downward. When the piston plate 604 moves downward to a certain position, it drives the limit block 609 to move downward. When the limit block 609 moves, it limits the T-shaped block 610, so that the T-shaped block 610 moves to the right. When the T-shaped block 610 moves to the right, the speed at which the liquid enters the oil cylinder 606 becomes slower and slower, thereby achieving a deceleration effect.

[0037] When installing the photovoltaic panel, put the photovoltaic panel into the support plate 301. The photovoltaic panel will contact the inclined surface of the triangular rod 304 and push the triangular rod 304 to move in the direction of the alarm 305. When the triangular rod 304 moves, it will push the insulating sheet 307 to move. When the insulating sheet 307 moves, it will be inserted into the inside of the alarm 305, so that the alarm 305 cannot sound the alarm. Turn the threaded rod 302 to push the clamping plate 303 to move in the direction of the photovoltaic panel. When the clamping plate 303 moves, it will clamp the photovoltaic panel. When the photovoltaic panel is normally disassembled, push the lower plate downward. The pressure rod 306 and the lower pressure rod 306 will be limited by the limiting rod 308 at the top of the triangular rod 304 when they move downward, so that the insulating sheet 307 cannot be separated from the inside of the alarm 305. During abnormal disassembly, the threaded rod 302 is rotated to move the splint 303 away from the photovoltaic panel. Under the elastic action of the No. 2 spring piece, the insulating sheet 307 will be separated from the alarm 305, thereby causing the alarm 305 to sound an alarm. The installation of the alarm 305 effectively prevents the photovoltaic panels from being stolen, thereby improving the safety of the photovoltaic equipment.

[0038] When the flip frame 2 flips upward, it will drive the fixed block 601 to flip upward. When the fixed block 601 flips, it will drive the arc plate 6 to flip. When the arc plate 6 flips, the protrusion on the arc plate 6 contacts the switch 7. Since the switch 7 is electrically connected to the motor 701, the motor 701 is running. When the motor 701 is running, it drives the rotating rod 716 to rotate. When the rotating rod 716 rotates, it drives the roller 702 to rotate. When the roller 702 rotates, under the action of the gear 713 and the rack 714, the roller 702 will roll on the surface of the photovoltaic panel. When the roller 702 rolls, it will clean the photovoltaic panel. When the rotating rod 716 rotates, it will push the blocking rod 707 to move, and the blocking rod 707 moves When the rotating rod 716 rotates, the supporting plate 704 will be driven to move, and the supporting plate 704 will slide on the left side of the support plate 301 when it moves. When the rotating rod 716 rotates, the curved plate 710 will also be driven to rotate. When the curved plate 710 rotates, it will intermittently contact the square rod 711, and the curved plate 710 will push the square rod 711 to move to the left. When the square rod 711 moves, it will push the baffle 709 to move. When the baffle 709 moves, the water in the water tank 706 will flow between the conduit 705 and the baffle pipe 708, and flow through the water pipe to the nozzle 703 in the drum 702. The nozzle 703 will intermittently spray water on the surface of the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel.
