Detailed Description

The utility model is further described in the following embodiments with reference to the figures, see fig. 1-5:

a push rod driven adjustment bracket, as shown in fig. 1-5, comprising:

a spud member 5 for being arranged on a basic fixture, such as a roof or floor. The fixing pile member 5 is used for supporting the photovoltaic main beam 4 and can place a photovoltaic panel on the photovoltaic main beam 4.

A support sleeve 6 is arranged at the upper end of the fixed pile member 5 and is used for carrying the photovoltaic main beam 4.

The driving member 1 is arranged on the fixed pile member 5, the driving member 1 comprises a swing arm 11, a push rod 12 and a support 13, one end of the push rod 12 is rotatably connected to one end of the swing arm 11, the other end of the push rod 12 is arranged on the support 13, the support 13 is arranged on the upright post 2, the other end of the swing arm 11 is arranged on the photovoltaic main beam 4, and a manual steering wheel or a portable electric tool can be selected as power equipment of the push rod 12 according to customer requirements.

The photovoltaic main beam 4 can be rotated when the driving member 1 is adjusted, so that the angle of the photovoltaic main beam 4 is changed, and the angle of the photovoltaic panel is adjusted.

The support sleeve 6 comprises a connecting seat 23 and a bearing 24. The inside of connecting seat 23 is annular, and bearing 24 sets up in the inside of connecting seat 23, and bearing 24 cover is established on photovoltaic girder 4. Thereby limiting the displacement of the photovoltaic girder 4 while rotating the photovoltaic girder 4 when adjusting the angle of the photovoltaic panel.

The drive member 1 comprises a swing arm 11 and a movable arm assembly 17. One end of the swing arm 11 is a fixed end 113, and the fixed end 113 is locked with the photovoltaic main beam 4. The other end of the swing arm 11 extends outwards to form a stress end 114, and the stress end 114 is used for receiving external driving force. One end of the movable arm assembly 17 is fixed on the fixed pile member 5, and the other end of the movable arm assembly 17 is hinged to the stress end 114 of the swing arm 11. When the stress end 114 is displaced, the fixed end 113 is locked with the photovoltaic main beam 4, and the photovoltaic main beam 4 is limited in the supporting sleeve member 6, so that the fixed end 113 can drive the photovoltaic main beam 4 to rotate, and the function of adjusting the angle of the photovoltaic panel is realized.

As shown in fig. 1-5, the movable arm assembly 17 includes a movable arm assembly outer tube 171, a plurality of pins 14, and a movable arm assembly inner tube 172, the movable arm assembly outer tube 171 and the movable arm assembly inner tube 172 being connected by the pins 14. The movable arm assembly inner tube 172 is movable inside the movable arm assembly outer tube 171, and the pin 14 is used to lock the movable arm assembly outer tube 171 and the movable arm assembly inner tube 172. One end of the movable arm assembly 17 is rotationally connected to one end of the swing arm 11, the other end of the movable arm assembly 17 is arranged on the upright post 2, the movable arm assembly 17 can be freely contracted, the angle of the swing arm 11 can be adjusted, and the use is more convenient.

When the angle of the photovoltaic panel needs to be adjusted, the pin shaft 14 needs to be taken out, so that the movable arm assembly outer tube 171 and the movable arm assembly inner tube 172 can move relatively again, and when the movable arm assembly inner tube 172 moves to the set position, the movable arm assembly outer tube 171 and the movable arm assembly inner tube 172 are locked by using the pin shaft 14 again, so that the movable arm assembly outer tube 171 and the movable arm assembly inner tube 172 can not move relatively any more. Because the angle of the photovoltaic panel needs to be adjusted less frequently each year, the angle to be adjusted is basically fixed, and the pin shaft 4 is used for controlling the distance that the movable arm assembly inner tube 172 can extend out of the movable arm assembly outer tube 171, the adjustment is performed without using extra equipment, and meanwhile, the adjustment is more accurate than on-site measurement, and the adjustment is more convenient for operation and maintenance personnel.

The outer periphery of the pin shaft 14 is sleeved with a shaft sleeve 15, and the shaft sleeve 15 is used for protecting the pin shaft 14 and preventing the pin shaft 14 from being worn and reducing the service life.

As shown in fig. 1 to 5, in the present embodiment, the fixed end 113 of the swing arm 11 is provided with three U-shaped bolts 112, and the U-shaped bolts 112 are used to tighten the shape of the photovoltaic main beam 4,U to match the profile of the photovoltaic main beam 4. When the stress end 114 is displaced, the fixed end 113 and the U-bolt 112 screwed with the fixed end 113 will tend to displace. Similarly, due to the limitation of the shape of the U-shaped bolt 113, the photovoltaic main beam 4 also tends to displace, and the photovoltaic main beam 4 is only driven to rotate because the photovoltaic main beam 4 is penetrated in the supporting sleeve 6 and is limited by the supporting sleeve 6 and cannot displace.

The three U-bolts 112 cooperate to form a tightening region, which is a region between two U-bolts 112 located outside in the longitudinal direction of the photovoltaic main beam 4 with reference to the longitudinal direction. A U-shaped backing plate 111 is arranged inside the tightening region, and the backing plate 111 is used for wrapping the photovoltaic main beam 4. The pressure of the U-shaped bolts 112 directly applied to the photovoltaic main beam 4 can be reduced through the base plates 111, so that excessive abrasion to the photovoltaic main beam 4 caused by the U-shaped bolts 112 when the photovoltaic main beam 4 is driven to rotate is avoided.

The two sides of the pad 111 extend out of the tightening region and form a blocking portion 115, wherein the blocking portion 115 on one side engages the bearing 24. The blocking portion 115 can limit the movement of the U-bolt 112 to tighten one end of the photovoltaic main beam 4, so that the U-bolt 112 cannot be separated from the tightening region. Meanwhile, in the installation process, the blocking part 115 can also play a role in positioning, and is convenient for an installer to position and complete the installation of the bracket.

As shown in fig. 1-5, the bearing 24 comprises two arc-shaped plastic sleeves, the two plastic sleeves are used for folding and holding the photovoltaic main beam 4, a groove which is matched with the photovoltaic main beam 4 is formed in the middle of each plastic sleeve, the photovoltaic main beam 4 can be limited in the connecting seat 23 through the bearing 24, and displacement and vibration of the photovoltaic main beam 4 are reduced.

Meanwhile, as the bearing 24 is composed of two plastic sleeves with the same shape, when one plastic sleeve is damaged, any plastic sleeve with the same kind can be used for replacement and maintenance, so that the maintenance difficulty is greatly reduced, and the cost of replacing parts is also reduced.

A baffle 241 is arranged on one side of the plastic sleeve close to the swing arm, and the outer edge of the baffle 241 protrudes out of the inner annular surface of the connecting seat 23. After the bearing 24 is sleeved on the outer side of the photovoltaic main beam 4, the bearing 24 can be moved on the photovoltaic main beam 4, so that the bearing 24 enters the connecting seat 23. The stopper 241 functions as a positioning for facilitating the fixing of the bearing 24 in the connecting seat 23.

As shown in fig. 1-5, the interior of the plastic sleeve is provided with a grating aperture 242. The grid holes 242 greatly reduce the materials required to fabricate the bearing 24 and reduce the cost of the bearing 24 while ensuring the structural strength of the bearing 24.

As shown in fig. 1 to 5, the fixed pile member 5 includes a base column 3 and a column 2, one end of the column 2 is fixedly mounted on the base column 3, and the other end of the column 2 is formed with a photovoltaic main beam 4.
