Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic technology, in particular to a torsion-resistant mechanism of a photovoltaic light-tracking system. Background Art

[0002] Photovoltaic power generation, that is, solar power generation, stands out among a group of clean energies due to its advantage of "being able to generate electricity as long as there is sunlight", making the photovoltaic industry still continuously developing, growing and commercializing.

[0003] In the prior art, a photovoltaic array is generally equipped with a light-tracking system, so that the photovoltaic panel can rotate according to the illumination angle to change its own inclination angle, thereby ensuring that the photovoltaic panel can face the sun for a long time to obtain the maximum power generation efficiency. The light-tracking system usually includes a driving column and a common column, and the top of each column is rotatably fitted with a main shaft; the main shaft is used to install the photovoltaic panel and is driven by a rotary motor installed on the driving column to drive the photovoltaic panel on the main shaft to adjust the angle, so as to achieve the effect of tracking the light.

[0004] Since the torque of the main shaft is mainly provided by the rotary motor on the driving column, the wind resistance stability at positions on both sides far from the driving column is poor. In a strong wind environment, the photovoltaic panels far from the driving column are prone to torsion, causing damage and destruction of the photovoltaic panels. Therefore, the product needs to be frequently overhauled and maintained, seriously affecting the application of the photovoltaic array in some wide, flat and windy environments. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a torsion-resistant mechanism of a photovoltaic light-tracking system, solve the problems existing in the prior art, and improve the wind resistance stability of a photovoltaic array equipped with a light-tracking system.

[0006] To achieve the above purpose, the solution of the utility model is:

[0007] A torsion-resistant mechanism of a photovoltaic light-tracking system includes a support column, a main shaft, a locking swing arm, a spring bolt and a driving device; the main shaft is rotatably fitted on the top of the support column; one end of the locking swing arm is fixedly installed on the circumferential surface of the main shaft, and the other end is provided with a locking hole; both the spring bolt and the driving device are installed on the support column; the bolt of the spring bolt is arranged opposite to the rotation trajectory of the locking hole so as to insert into the locking hole, and the spring of the spring bolt is used to drive its bolt to disengage from the locking hole; when the driving device works, it drives the bolt of the spring bolt to insert into the locking hole adjusted in place.

[0008] A rotating bearing through which the main shaft passes is installed on the top of the support column.

[0009] The locking hole is an elongated hole extending along the radial direction of the main shaft.

[0010] The spring bolt further includes a bracket fixedly installed on the strut, the bolt and the spring are arranged inside the bracket, and the bracket is provided with a through hole for the bolt to movably pass through.

[0011] The driving device is a motor, a push rod or a cylinder that outputs linear reciprocating motion.

[0012] After adopting the above technical solution, the utility model has the following technical effects:

[0013] After being put into application, in windy weather, the rotary motor of the photovoltaic array can be automatically controlled by the control box of the photovoltaic array, or manually controlled by a person to make it work and drive the main shaft to drive the photovoltaic panel to return to a flat state. When the photovoltaic panel returns to a flat state, the locking hole of the locking swing arm is opposite to the bolt of the spring bolt. Then the driving device works to push the bolt to compress the spring and insert the bolt into the locking hole to lock the locking swing arm. By limiting the locking swing arm with the bolt, the torsional resistance between the main shaft and the strut is improved, and the photovoltaic panel is prevented from being damaged due to windy weather.

[0018] In order to further explain the technical solution of the utility model, the utility model will be elaborated in detail below through specific embodiments.

[0019] Refer to Figure 1-2 As shown, the utility model discloses a torsional resistance mechanism of a photovoltaic light - tracking system, including a strut 1, a main shaft 2, a locking swing arm 3, a spring bolt 4 and a driving device 5;

[0020] The strut 1 is fixed to the installation surface of the photovoltaic array (such as positions suitable for installing the photovoltaic array like the ground, roof, rooftop, etc.);

[0021] The main shaft 2 is rotationally fitted at the top of the strut 1 and is used for installing the photovoltaic panel of the photovoltaic array;

[0022] One end of the locking swing arm 3 is fixedly installed on the circumferential surface of the main shaft 2, and the other end is provided with a locking hole 31;

[0023] The spring bolt 4 and the driving device 5 are both installed on the support column 1; the bolt 41 of the spring bolt 4 is arranged opposite to the rotation track of the locking hole 31 so as to penetrate into the locking hole 31, and the spring 42 of the spring bolt 4 is used to drive its bolt 41 to disengage from the locking hole 31;

[0024] When the driving device 5 works, it drives the bolt 41 of the spring bolt 4 to insert into the adjusted locking hole 31.

[0025] Through the above scheme, after the utility model is put into application, in windy weather, the rotary motor of the photovoltaic array can be automatically controlled by the control box of the photovoltaic array, or manually controlled by a person, so that it works and drives the main shaft 2 to drive the photovoltaic panel to return to a horizontal position. When the photovoltaic panel returns to a horizontal position, the locking hole 31 of the locking swing arm 3 is opposite to the bolt 41 of the spring bolt 4. Then the driving device 5 works to push the bolt 41 to compress the spring 42 and make the bolt 41 insert into the locking hole 31 to lock the locking swing arm 3. By limiting the locking swing arm 3 with the bolt 41, the torsional resistance performance between the main shaft 2 and the support column 1 is improved, and the photovoltaic panel is prevented from being damaged due to windy weather.

[0026] The following shows the specific embodiments of the utility model.

[0027] The above support column 1 is a common column of the photovoltaic array, that is, a column without a rotary motor installed, ensuring that the position of the main shaft 2 far from the rotary motor has sufficient torsional resistance performance.

[0028] A rotating bearing 6 for the main shaft 2 to pass through is installed at the top of the above support column 1, which can improve the stability of the main shaft 2.

[0029] The above locking hole 31 is an elongated hole extending along the radial direction of the main shaft 2, so that the locking hole 31 has a certain length, so that the bolt 41 can be inserted into the locking hole 31 more easily, improving the fault tolerance.

[0030] The above spring bolt 4 further includes a bracket 43 fixedly installed on the support column 1. The bolt 41 and the spring 42 are arranged inside the bracket 43, and the bracket 43 is provided with a through hole 431 for the bolt 41 to move through.

[0031] The above driving device 5 is a motor, a push rod or a cylinder capable of outputting linear reciprocating motion.

[0032] The utility model can also cooperate with a wind speed sensor to achieve automation. For example, the working process of the utility model can be:

[0033] (1) The wind speed sensor monitors the wind speed in the environment in real time;

[0034] (2) When the wind speed is greater than the set threshold, the control box starts the rotary motor on the driving column to control the photovoltaic panel to return to a horizontal position;

[0035] (3) The control box activates the driving device 5 on the ordinary column, so that the driving pin 41 compresses the spring 42, passes through the bracket 43 and then inserts into the locking hole 31 of the locking swing arm 3 to keep the photovoltaic panel in a flattened state;

[0036] (4) When the wind speed sensor monitors the end of the strong wind, the control box activates the driving device 5 to make it return, and the spring 42 releases its elastic potential energy to drive the pin 41 out of the locking hole 31;

[0037] (5) The photovoltaic light tracking system continues to operate normally.

[0038] The above embodiments and diagrams do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present invention.
