Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic bracket angle adjustment equipment, in particular to a dual-axis tracking altitude angle adjustment device. Background Art

[0002] Solar power generation is a renewable energy technology, but the position of the sun changes every moment. Therefore, how to efficiently utilize sunlight is a core issue that must be addressed. Since the position of the sun is constantly changing, the receiving surface must also be constantly oriented to the optimal position, so it is necessary to track the sun. At present, the most common tracking device is driven by an electric push rod. After the motor is reduced by gears or worm gears, it drives a pair of screw nuts to convert the motor's rotational motion into linear motion. The motor's forward and reverse rotation completes the up and down movement of the push rod, thereby achieving angle adjustment of the altitude angle.

[0003] The traditional dual-axis tracking height angle adjustment device adopts several methods such as electric push rod drive, hydraulic push rod drive, and worm gear reducer. These traditional drive methods and traditional installation methods are high in cost, low in precision, and inconvenient in installation and maintenance. They are technical problems that need to be solved urgently in the existing technology. Among them, the most important disadvantage of these traditional methods is the need to purchase relatively expensive drivers and reducers. Therefore, it is difficult for traditional dual-axis tracking height angle adjustment devices to achieve cost reduction and efficiency improvement in this regard. The height angle adjustment device of the utility model adopts an innovative solution that combines a drive rope with a linear drive structure and uses an ordinary motor and reducer drive, which well achieves cost reduction and efficiency improvement in this regard, making the product more competitive in the market.

[0006] The axle up and down groove at two ends embeds respectively in two guide rails up and down of being made up of the groove on the attachment piece, and the tooth on the attachment piece is meshed with tooth on upper sprocket wheel, the lower sprocket.

[0007] Specifically, the fixed mounting plate is used for supporting and thus supporting the installation of the main beam and the driving wheel, and the lower end of the fixed mounting plate is fixedly connected to the driving mounting frame.

[0008] Specifically, an upper transmission wheel, a top wheel 1 and a top wheel 2 are provided in the fixed installation plate. The upper transmission wheel, the top wheel 1 and the top wheel 2 are all rotatably connected in the fixed installation plate, thereby limiting the transmission rope.

[0009] Specifically, the motor drives the screw rod to rotate and connect, and a screw rod movable plate is threadedly connected to the screw rod, and the screw rod movable plate is driven to slide along the shell through the contact of the screw rod movable plate on the screw rod movable plate.

[0010] Specifically, the screw movable plate is fixedly connected to the round rod 1 and the round rod 2, thereby driving the round rod connecting plate 1 and the round rod connecting plate 2 to adjust their positions.

[0011] Specifically, the fixing plate is used to fix the housing and limit the screw movable plate. At the same time, the housing is used to fix the motor. The round rod connecting plate 1 and the round rod connecting plate 2 are connected to the upper limit with a transmission rope.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages and effects:

[0013] Common elevation angle drive devices include worm gear reducers, rack and pinion gears, hydraulic push rods, and electric push rods. These traditional drive methods and traditional installation methods are costly, have low precision, and are inconvenient to install and maintain. They are technical problems that need to be urgently solved in the existing technology. The main disadvantage is that it is necessary to purchase relatively expensive drivers and reducers, so that the traditional dual-axis tracking elevation angle adjustment device is difficult to achieve cost reduction and efficiency improvement in this regard.
