DETAILED DESCRIPTION

[0031] like Figure 1-6 As shown, this embodiment includes a mounting base 1, a slide rod 2, a push rod mechanism 3, a photosensor and a controller.

[0032] The mounting base 1 is a rectangular plate structure, and the top surface of the mounting base 1 is used to install the photovoltaic panel 6. In this embodiment, four corner pieces 4 are used to install the photovoltaic panel 6 on the mounting base 1. Specifically, the corner piece 4 is composed of two vertical plates 4a and one horizontal plate 4b arranged perpendicular to each other. The two vertical plates 4a of the corner piece 4 are fixed to the two vertical sides at the corners of the mounting base 1 by bolts. The horizontal plate 4b of the corner piece 4 and the top surface of the mounting base 1 are provided with a gap to accommodate the photovoltaic panel 6, and the four corners of the photovoltaic panel 6 are arranged in the gap to be clamped thereby.

[0033] There are four photosensitive sensors, which are respectively arranged on the horizontal plates 4b of the four corner pieces 4. The photosensitive sensors respectively collect light intensity information at four points and send the information to the controller.

[0034] In this embodiment, a first sliding groove 1 a and a second sliding groove 1 b are provided on the bottom surface of the mounting seat 1 .

[0035] The first slide groove 1a has a major arc section and is in the shape of an elongated strip. The first slide groove 1a is parallel to and close to one side of the mounting seat 1 and also penetrates the mounting seat 1.

[0036] The second slide groove 1b is perpendicular to the first slide groove 1a, that is, the second slide groove 1b is perpendicular to the first slide groove 1a in the sliding direction, and the second slide groove 1b is in the shape of a U. The slide bar 2 is arranged in the second slide groove 1b and can slide back and forth in the second slide groove 1b, that is, the slide bar 2 is parallel to the first slide groove 1a but can slide back and forth along the direction perpendicular to the first slide groove 1a. The slide bar 2 is provided with a third slide groove 2a parallel to the first slide groove 1a, and the cross section of the third slide groove 2a is also in the shape of a major arc. The third slide groove 2a runs through the entire slide bar 2.

[0037] In order to further ensure the smoothness of sliding, a plurality of first rolling grooves 1b1 are arranged on the two side portions of the second slide groove 1b, and the cross section of the first rolling groove 1b1 is a minor arc shape. Second rolling grooves 2a1 corresponding to the first rolling groove 1b1 are arranged at both ends of the slide bar 2, and the cross section of the second rolling groove 2a1 is also a minor arc shape corresponding to the shape of the first rolling groove 1b1. Balls are also included, and the balls are arranged between the first rolling groove 1b1 and the second rolling groove 2a1. In this way, the friction resistance of the slide bar 2 in the second slide groove 1b can be effectively reduced by the rolling of the balls.

[0038] The push rod mechanism 3 of this embodiment adopts an electric push rod. In other embodiments, the push rod mechanism 3 may also adopt a cylinder or a hydraulic cylinder or a connecting rod mechanism. In this embodiment, a base 3a is provided at the bottom end of the electric push rod, and the base 3a can be fixed to the bottom surface by bolts. A ball is provided at the output end of the electric push rod. There are four electric push rods and they are evenly divided into two groups. The ball of one group of electric push rods is just set in the first slide groove 1a and can rotate and slide in the first slide groove 1a. Specifically, the installation method is to slide in from both ends of the first slide groove 1a.

[0039] The ball of the other set of electric push rods is just arranged in the third slide groove 2a and can rotate and slide in the third slide groove 2a. When installing, it also slides into the third slide groove 2a from both ends, and then slides the slide rod 2 into the second slide groove 1b from the opening of the second slide groove 1b.

[0040] The four electric push rods of this embodiment are arranged in parallel and in a rectangular shape. The four electric push rods are controlled by a controller, and the control area controls the pushing lengths of the four electric push rods respectively according to the light intensity information transmitted by the four photosensors.

[0041] Preferably, the two vertical plates 4a of the two corner pieces 4 in this embodiment can block the two ends of the first slide groove 1a and the two sides of the opening end of the second slide groove 1b. Therefore, the corner piece 4 not only plays the role of clamping the photovoltaic panel 6, but also plays the role of preventing the ball from sliding down from the first slide groove 1a and the third slide groove 2a.

[0042] Preferably, the present embodiment is further provided with a soft plug 5, which is arranged at both ends of the first slide groove 1a and the third slide groove 2a. The soft plug 5 can buffer the impact of the ball on the corner piece 4.

[0043] This embodiment also provides a control method, comprising the following steps:

[0044] A1: To level the photovoltaic panel, the controller obtains the initial extension positions of the four push rods as initial data;

[0045] A2: Control the sensor to obtain the output information of four photosensitive sensors;

[0046] A3: Based on the highest light intensity obtained, the controller controls the other three push rods to push and pull. Since the initial extension position information of the four push rods is obtained, the displacement speed of the other three push rods can be deduced through simple calculations when the other three push rods are doing push and pull movements, so as to ensure that the spheres of the four push and pull mechanisms are always on the same plane during the movement.

[0047] A4: When the values ​​detected by the other three photosensitive sensors are the same as or similar to the base point, the controller controls the push rod mechanism to stop moving.

[0048] Preferably, the method further comprises step A5: repeating steps A2-A4 at fixed time intervals.

[0049] The method can be used to most quickly and automatically adjust the angle of the photovoltaic panel 6 .

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
