The left and right sides of the seat, the rotating arm is installed on the rotating bearing, and the driving arm driven by the screw that can slide along the front and rear direction of the rotating arm is arranged in the rotating arm, and the vertical arm and the rotating arm are connected by a rotating shaft. The erecting arm is hingedly connected with the driving arm through a connecting rod, the limit mechanism is arranged on the rotating arm between the mounting seat and the rotating shaft, and the hand-operated device is installed at one end of the rotating arm.

A further technical solution of the present invention is: the number of the connecting rods is two, which are respectively located on the left and right sides of the lead screw.

A still further technical solution of the present invention is: the mounting seat is located in the middle of the rotating arm.

A further technical solution of the present invention is: the mounting holes are evenly distributed on the mounting base.

Furthermore, the mounting holes are threaded mounting holes.

Furthermore, the lead screw is perpendicular to the driving arm.

Compared with the prior art, the present invention has the following characteristics: the device for manually controlling the pitch and rotation of photovoltaic panels provided by the present invention drives the lead screw by rotating the hand-operated device, the movement of the lead screw drives the drive arm to move left and right, and the drive arm moves toward the hand-operated The device moves in the direction, and the vertical arm can be raised through the connecting rod. When the vertical arm rises to a suitable angle, stop the hand crank, and the self-locking function of the lead screw can keep the vertical arm at an angle, and rotate in the opposite direction when it is lowered. With the hand-operated device, the vertical arm will fall back under the action of gravity, thereby realizing the pitching characteristics of the photovoltaic panel; in addition, through the rotating bearing, the rotating arm is gently pushed by hand, and the position is locked by the limit mechanism. Adjust the angle between the photovoltaic panel and the sunlight according to the direction of the panel, which is beneficial to improve the power generation efficiency of the solar photovoltaic panel; the device is simple, the cost is low, and it can be installed on a small power station or a cabin car, which is economical and convenient.

The detailed structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

detailed description

As shown in the drawings: a device for manually controlling the pitch and rotation of photovoltaic panels, characterized in that it includes a mounting base 6, a rotating bearing 5, a rotating arm 3, a connecting rod 4, a limit mechanism 2, a vertical arm 7, a hand Shake device 8, rotating bearing 5 is positioned at the left and right sides of mounting base 6, and rotating arm 3 is installed on the rotating bearing 5, and rotating arm 3 is provided with the drive arm 10 driven by lead screw 9 that can slide along rotating arm 3 front and rear directions , the vertical arm 7 is connected to the rotating arm 3 through the rotating shaft 1, the vertical arm 7 is connected to the driving arm 3 through the connecting rod 4, and the limit mechanism 2 is arranged on the rotating arm 3 between the mounting seat 6 and the rotating shaft 1 On, hand-operated device 8 is installed on one end of rotating arm 3.

The number of connecting rods 4 is two, which are respectively located on the left and right sides of the lead screw, which can ensure that the balance stability of the vertical arm 7 is relatively high when pitching.

The mounting base 6 is located in the middle of the rotating arm 3, which ensures the high balance and stability of the entire pitching device; the mounting base 6 is evenly distributed with mounting holes 6-1; the mounting holes 6-1 are threaded mounting holes, which is convenient for the installation of the mounting base 6 .
