Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, and in particular to a rooftop photovoltaic panel anti-fall fixing device. Background Technology

[0002] A photovoltaic (PV) panel is a device that converts sunlight into electrical energy. Through the photoelectric effect, it converts light energy into direct current (DC), and is widely used in homes, businesses, and industries to provide clean and renewable energy. PV panels utilize the characteristics of semiconductor interfaces to convert solar radiation into DC electricity through the photoelectric or photochemical effects. This process does not involve mechanical movement or combustion, thus offering significant advantages such as cleanliness, zero pollution, and renewability. The working principle of a PV panel is based on the photoelectric effect. When sunlight shines on the surface of a solar cell, photons interact with electrons in the cell, exciting photogenerated charge carriers—electron-hole pairs. Due to the electric field in the semiconductor, these photogenerated charge carriers with opposite charges are separated by the built-in electric field of the PN junction of the cell. Electrons concentrate on one side, and holes concentrate on the other, resulting in the accumulation of opposite charges on both sides of the PN junction, forming a photogenerated electromotive force. When electrodes are led out at both ends of the cell and a load is connected, a photogenerated current flows through the external circuit, thus obtaining power output and directly converting solar energy into electrical energy.

[0003] Because of their high location and minimal obstructions, rooftops are an ideal location for installing photovoltaic (PV) panels. A Chinese utility model patent (CN221448342U) entitled "PV Panel Connection Structure for Rooftop PV Support" describes a system that uses a PV panel, mounting plate, adjusting cylinder, screw, support shaft, adjusting plate, mounting clamp, and tilt angle adaptation mechanism. This system allows multiple adjusting cylinders to rotate, driving the screw to adjust the height and change the tilt angle of the PV panel. While this application uses adjusting cylinders and screws to adjust the PV panel angle, this adjustment requires manual operation. Furthermore, the two adjusting cylinders and screws on the same side must move synchronously to avoid jamming, making PV panel adjustment inconvenient. Additionally, the lack of a fall protection structure during PV panel installation makes them prone to falling if they become loose, resulting in low safety when PV panels are installed on rooftops.

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] Figures 1 to 6 The diagram shown is a structural schematic of an embodiment of the rooftop photovoltaic panel anti-fall fixing device of this utility model. The rooftop photovoltaic panel anti-fall fixing device includes a photovoltaic panel mounting frame 1 and a photovoltaic panel body 2, wherein the photovoltaic panel body 2 is installed inside the photovoltaic panel mounting frame 1.

[0057] Anti-fall fixing components 3 are provided at the four corners of the photovoltaic panel mounting frame 1. The anti-fall fixing components 3 are used to limit the position of the photovoltaic panel body 2.

[0058] An angle control unit is located below the photovoltaic panel mounting frame 1 and is connected to the top of the roof mounting frame 7. The angle control unit is used to adjust and control the tilt angle of the photovoltaic panel body 2.

[0059] The angle control unit includes a lifting control component 4, a connecting component 5, and a drive control component 6.

The connecting component 5 is connected to the bottom of the photovoltaic panel mounting frame 1, and the drive control component 6 is connected to the top of the roof mounting frame 7.

[0060] In this technical solution, the angle control system can control the angle of the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2, so that the photovoltaic panel body 2 can receive sunlight. The control is manual and the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2 can be adjusted simultaneously on one side, making the angle adjustment of the photovoltaic panel body 2 more flexible and preventing jamming. Furthermore, the anti-fall fixing component 3 can limit the position of the photovoltaic panel body 2 when it becomes loose, preventing the photovoltaic panel body 2 from falling and improving the safety of the photovoltaic panel body 2 when installed on the roof. It also facilitates the installation and use of the photovoltaic panel on the photovoltaic panel body 2.

[0061] The anti-fall fixing component 3 includes a rotating shaft 31, the surface of which is rotatably and through-connected to the photovoltaic panel mounting frame 1;

[0062] The top end of the rotating shaft 31 is connected to a fall arrestor plate 32.

[0063] In this technical solution, the anti-fall fixing component 3 can be used to prevent the photovoltaic panel body 2 from falling.

[0064] The bottom end of the rotating shaft 31 is connected to a fixed gear 33, and a locking rack 34 is provided on the side of the fixed gear 33. When the fixed gear 33 and the locking rack 34 are in contact, they engage.

[0065] One side of the locking rack 34 is connected to one side of the locking fixing plate 35, and the locking fixing plate 35 is detachably connected to the bottom of the photovoltaic panel mounting outer frame 1 by multiple mounting bolts 36.

[0066] In this technical solution, the angles of structures such as the fixed gear 33 and the anti-fall strip plate 32 can be locked using the mounting bolt 36 and the locking rack 34.

[0067] During installation, the rotating shaft 31 can be rotated, thereby driving the anti-fall strip 32 to rotate. When the anti-fall strip 32 is rotated, the photovoltaic panel body 2 is above it.

[0068] Then, the locking plate 35 is fixed to the bottom of the photovoltaic panel mounting frame 1 using the mounting bolts 36. At this time, the locking rack 34 is engaged with the side of the fixing gear 33. The locking rack 34 locks the angle of the fixing gear 33, thereby locking the angle of the rotating shaft 31 and the anti-fall strip 32. The anti-fall strip 32 limits the position of the photovoltaic panel body 2 to prevent the photovoltaic panel mounting frame 1 from falling.

[0069] The lifting control component 4 includes a sliding block 41, and two symmetrically distributed sliding blocks 41 are provided above the roof mounting plate frame 7;

[0070] The top of each of the two sliding blocks 41 is connected to a lifting device 42, and the top of each of the two lifting devices 42 is connected to a synchronous frame 43. The synchronous frame 43 is movably connected to the connecting component 5.

[0071] In this technical solution, the height of the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2 can be adjusted and controlled by the lifting control component 4.

[0072] In use, the lifting devices 42 on both sides can drive the synchronous frame 43 to move in the same direction, thereby driving the connecting component 5, the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2 to move in the same direction, and the height of the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2 and other structures can be adjusted.

[0073] Meanwhile, the lifting devices 42 on both sides can be adjusted independently, thereby cooperating with the drive control component 6 and the connecting component 5 to adjust the angle of the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2, so as to facilitate the photovoltaic power generation operation of the photovoltaic panel body 2.

[0074] The connecting component 5 includes a fixed side plate 51. The bottom of the photovoltaic panel mounting frame 1 is connected to two symmetrically distributed fixed side plates 51, and multiple fixed columns 52 are connected between the fixed side plates 51 on both sides.

[0075] The fixed column 52 has two symmetrically distributed follower plates 53 slidably connected to its surface. The follower plates 53 have two symmetrically distributed central columns 54 at their bottom. Both ends of the central columns 54 are connected to connecting side plates 55. The top of the connecting side plates 55 is connected to the bottom of the follower plates 53.

[0076] The surface of the central column 54 is rotatably connected to the rotating block 56, and the bottom of the rotating block 56 is connected to the top of the follower plate 53.

[0077] In this technical solution, the connecting component 5 allows the photovoltaic panel mounting frame 1 to change its angle as the lifting control component 4 operates.

[0078] The drive control component 6 includes a two-way telescopic device 61, which is connected to the top of the roof mounting frame 7.

[0079] Both output ends of the bidirectional telescopic device 61 are connected to push-pull plates 62, and the top of the push-pull plates 62 is connected to the bottom of the sliding block 41.

[0080] The sliding block 41 is slidably connected to the surface of the support column 63. Both ends of the support column 63 are connected to the support side plate 64. The bottom of the support side plate 64 is connected to the top of the roof mounting frame 7.

[0081] In this technical solution, the position of the lifting control component 4 can be adjusted by the drive control component 6, which facilitates the adjustment of the angles of structures such as the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2.

[0082] Both sides of the push-pull plate 62 are provided with support side plates 64, one of which has a preset opening. The output end of the two-way telescopic device 61 is connected to the support side plate 64 through the preset opening.

[0083] In this technical solution, the support column 63 can be supported by the support side plate 64.

[0084] A plurality of support columns 63 are connected between the two support side plates 64, and the surfaces of the support columns 63 are slidably connected through the support columns 63.

[0085] In this technical solution, the movement trajectory of the sliding block 41 can be limited by the support column 63.

[0086] The cross-section of the synchronization frame 43 is U-shaped, and rotating blocks 56 are connected to both ends of the top of the U-shaped structure.

[0087] In use, the drive control component 6 can drive the support columns 63 on both sides to move. When the support columns 63 move, the sliding block 41 can move in the same direction as the support columns 63. This can drive the sliding block 41, the synchronous frame 43, and the follower plate 53 to move in the same direction. This can adjust the position of the lifting control component 4 on the lifting point of the photovoltaic panel mounting frame 1, so as to adjust the angle of the photovoltaic panel mounting frame 1 and the photovoltaic panel body 2.

[0088] In this technical solution, the synchronous frame 43 enables the two force application points on the same side of the photovoltaic panel mounting frame 1 to operate synchronously.

[0089] The top of the supporting side plate 64 and the bottom of the photovoltaic panel mounting frame 1 are both connected to anti-fall nets 8.

[0090] In this technical solution, the anti-fall net 8 can be used to prevent the photovoltaic panel installation frame 1 from falling.

[0091] The lifting device 42 and the two-way telescopic device 61 are devices with autonomous telescopic functions, such as electric push rod assembly, lifting cylinder assembly, and hydraulic lifting cylinder assembly.
