[0022] See also Figure 1-5The present embodiment provides an intelligent retractable solar bracket, including a bracket body 1, a storage chamber 9, a monitoring system 10 and a slide rail 8. The bracket body 1 includes a plurality of folding frames 2 arranged side by side. The folding frames 2 include a first rotating connection device and two photovoltaic fixing frames 3. The two photovoltaic fixing frames 3 are arranged opposite to each other. The adjacent sides of the two photovoltaic fixing frames 3 in the same folding frame 2 are connected by the first rotating connection device. A second rotating connection device is provided between the two adjacent folding frames 2. The adjacent sides of the photovoltaic fixing frames 3 of the two adjacent folding frames 2 are connected by the second rotating connection device. Telescopic support rods 6 are fixed to the opposite sides of the photovoltaic fixing frames 3. A pulley 7 is fixed to the bottom of the telescopic support rods 6. A solar photovoltaic panel 20 is fixed to the photovoltaic fixing frames 3.

[0023] One end of the bracket body 1 is a fixed end 11, and the other end is a movable end 12. The storage chamber 9 is fixed at the fixed end 11 of the bracket body 1 ( Figure 1 The monitoring system 10 is fixed on the top of the storage room 9. The monitoring system 10 includes an environment monitor and a controller. The electric pulley 71 and the environment monitor are electrically connected to the controller. The environment monitor includes a wind speed monitoring and weather warning module. The weather warning module is connected to the network through a network interface. The storage room 9 protects the folded support body 1 and the solar photovoltaic panel 20. The environment monitor monitors the external environment in real time. When the external environment is threatened by rain or strong wind, the controller controls the electric pulley 71 to move toward the fixed end 11, and the support body 1 shrinks.

[0024] An automatic spray system 91 is provided on the top of the storage chamber 9, and the automatic spray system 91 is electrically connected to the controller. When the solar photovoltaic panel 20 needs to be cleaned, the folding frame 2 is retracted into the storage chamber 9, and the controller turns on the automatic spray system 91 to clean the solar photovoltaic panel 20.

[0025] In this embodiment, the automatic sprinkler system 91 includes a sprinkler head, a water inlet pipe and an electric valve, and the controller is used to control the opening and closing of the electric valve.

[0026] The photovoltaic fixing frame 3 includes a fixed frame 31 and a plurality of reinforcing rods 32. The reinforcing rods 32 connect the two opposite sides of the fixed frame 31. The photovoltaic fixing frame is provided with a mounting buckle 33. The back of the solar photovoltaic panel 20 is engaged with the mounting buckle 33. The reinforcing rods 32 and the fixed frame 31 are fixed to form a grid structure, which improves the rigidity of the photovoltaic fixing frame 3. The mounting buckle 33 facilitates the rapid installation of the solar photovoltaic panel.

[0027] The telescopic support rod 6 of the photovoltaic fixed frame 3 near the fixed end 11 is fixed to the ground, the pulley 7 on the bottom surface of the telescopic support rod 6 of the photovoltaic fixed frame 3 near the movable end 12 is an electric pulley 71, the slide rail 8 is extended in the parallel direction of the folding frame 2, and the pulley 7 is slidably arranged in the slide rail 8. The electric pulley 71 realizes the automatic contraction and extension of the solar bracket, and the pulley 7 slides along the slide rail 8 in an orderly manner.

[0028] In this embodiment, there are two slide rails 8, and a telescopic support rod 6 is fixed on both sides of the bottom edge of each photovoltaic fixing frame 3. When in use, the telescopic support rods 6 on the two slide rails 8 are adjusted to extend to different heights, and the height of the telescopic support rods 6 on the same slide rail 8 is the same. The photovoltaic fixing frame 3 allows the solar photovoltaic panel 20 to be tilted to a corresponding angle after installation, and then the adjustment of the height of the telescopic support rods 6 on both sides of the photovoltaic fixing frame 3 can adjust the tilt angle of the solar photovoltaic panel 20, thereby improving the power generation efficiency.

The top of the connecting columns 34 is fixed with a boss, and the boss is engaged with the side of the slide groove 51. The setting of the connecting plate 5 is conducive to the connection and fixation of two adjacent photovoltaic fixing frames 3, and prevents the hinges 4 from being subjected to too much pulling force on the two sides while rotating the connection, and effectively ensures the service life of the hinges 4.

[0030] The telescopic support rod 6 includes a supporting bottom tube 61 and a connecting rod 62. The bottom end of the connecting rod 62 is sleeved in the supporting bottom tube 61. The top end of the connecting rod 62 is rotatably connected to the photovoltaic fixing frame 3. A plurality of locking holes are provided on the side of the supporting bottom tube 61. Locking screws 63 are provided in the locking holes. The bottom end of the connecting rod 62 is fixed to the supporting bottom tube 61 by the locking screws 63.

[0031] The supporting bottom tube 61 and the connecting rod 62 are sleeved with each other. When extension is required, the connecting rod 62 is lifted upwards for a certain distance and then the locking screw 63 is tightened to fix it. Otherwise, the telescopic supporting rod 6 is retracted.

[0032] In another embodiment, the telescopic support rod 6 can also be replaced by a telescopic cylinder to perform electric control.

[0033] When this embodiment is used:

[0034] When it is needed, the controller controls the electric pulley 71 of the folding frame 2 at the movable end 12 to slide outward along the guide rail, driving all the folding frames 2 of the entire bracket body 1 to unfold, and then the fixed angle of the solar photovoltaic panel 20 is adjusted by telescopic support rod 6.

[0035] When encountering strong winds or the bracket needs to be cleaned, the controller controls the electric pulley 71 to retract inward, and the bracket body 1 is folded and retracted into the storage chamber 9. When cleaning is required, the automatic spray system 91 cleans the bracket.

[0036] In the present invention, the folding and storage of two photovoltaic fixed frames 3 are completed in the same folding frame 2 through a first rotating connection device, and then the two adjacent folding frames 2 are connected by a second rotating connection device. The telescopic support rod 6 at the bottom of the photovoltaic fixed frame 3 can be adjusted in height, thereby adjusting the inclination angle of a single folding frame 2 after unfolding, and then adjusting the installation angle of the photovoltaic panel to adapt to the different incident angles of sunlight at different times, thereby improving the power generation efficiency of the solar photovoltaic panel.
