Description

TECHNICAL FIELD

[0002] A photovoltaic panel is an energy conversion device that converts solar energy into electrical energy to power various devices. Solar photovoltaic panels have a wide range of applications, including but not limited to power supply in the fields of household, commercial and industrial.

[0003] Photovoltaic panels have two installation methods, including fixed installation and tracking installation. The fixed installation angle is fixed and does not adjust the angle to follow the sunlight. The tracking installation adjusts the angle of illumination to follow the sunlight. Compared with fixed installation, tracking installation can improve power generation. The double-axis in tracking installation mainly rotates the azimuth axis to find the azimuth angle of the sun in the sky and rotates the altitude axis to find the best illumination height angle of the sunlight to obtain better electrical energy conversion.

[0004] However, the transmission mechanism (such as gears, bearings and drive motors) of the conventional photovoltaic panel double-axis tracking may significantly increase the wind load when the photovoltaic panel is at the optimal angle under strong wind conditions, causing the transmission components to bear torque and bending moment beyond the design range. Therefore, there is a lack of effective active protection mechanism to deal with sudden strong wind weather. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0027] The present disclosure will be further described in conjunction with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0028] As Figure 1 As Figure 6 shown in the embodiment, a photovoltaic panel dual-axis automatic sunlight tracking optimization device includes a photovoltaic panel 1, a support rod 2, an azimuth axis 3, and a height axis 4. The height axis 4 is installed on the back light side of the photovoltaic panel 1, and the azimuth axis 3 is installed on the upper part of the support rod 2. The device further includes an azimuth limiting disc set, an azimuth sliding assembly, an azimuth rotating rod 5, a gear set, a height limiting rod 6, and an anemometer 7.

[0029] The anemometer 7 is installed on the photovoltaic panel 1. When the anemometer 7 detects that the wind speed reaches the set wind speed interval, the height angle and the azimuth angle are adjusted by controlling the azimuth axis 3 and the height axis 4. The azimuth limiting disc set is coaxially installed on the support rod 2 and the azimuth axis 3. The azimuth sliding assembly is coaxially installed on the support rod 2 and in the azimuth limiting disc set. The azimuth sliding assembly can move up and down on the support rod 2. When the azimuth sliding assembly slides downward, it can be embedded in the azimuth limiting disc set, thereby limiting the rotation of the azimuth axis 3. The azimuth rotating rod 5 is fixedly connected to the azimuth axis 3. The height axis 4 is installed at the top end of the azimuth rotating rod 5. The gear set is coaxially installed on the back light side of the photovoltaic panel 1. The azimuth rotating rod 5 is provided with a limiting through hole. The height limiting rod 6 penetrates through the limiting through hole and can be embedded in the gear set to limit the rotation of the gear set, thereby limiting the rotation of the height axis 4.

[0030] The azimuth sliding assembly includes a sliding disc 101 and a limiting rod 102. The sliding disc 101 is coaxially and slidingly connected to the support rod 2. A plurality of limiting rods 102 are equiangularly and circumferentially arranged on the sliding disc 101, and the limiting rods 102 penetrate through the sliding disc 101.

[0031] As Figures 1 to 3As shown, in this embodiment, to ensure the rotation angle of the azimuth axis 3 can be limited, the azimuth limiting disk assembly includes: limiting disk one 201 and limiting disk two 202. Limiting disk one 201 is coaxially mounted on the azimuth axis 3. Limiting disk one 201 has multiple hollow through holes adapted to the limiting rod 102 arranged on its circumference at equal angles. Limiting disk two 202 is coaxially mounted on the support rod 2. Limiting disk two 202 has multiple hollow through holes adapted to the limiting rod 102 arranged on its circumference at equal angles. The azimuth sliding component is limited by limiting disk one 201. The azimuth sliding component slides up and down between 01 and the second limiting disk 202. Under normal power generation conditions of photovoltaic panel 1, the limiting rod 102 of the azimuth sliding component is only embedded in the hollow through hole of the second limiting disk 202, which does not affect the rotation of the first limiting disk 201 on the azimuth axis 3. However, in strong wind weather, the azimuth axis 3 rotates at an angle with a smaller wind load so that the limiting hole and the limiting rod 102 are aligned. The azimuth sliding component rises and is embedded in the hollow through hole of the first limiting disk 201 and the second limiting disk 202, thereby fixing the rotation angle of the azimuth axis 3.

[0032] like Figures 1 to 6 As shown, in this embodiment, the gear set includes: an arc gear 301, a circular gear 302, and a height angle limiting post. The arc gear 301 is coaxially mounted with the height shaft 4 on the backlight side of the photovoltaic panel 1. The circular gear 302 is mounted on the azimuth rotating rod 5 and meshes with the arc gear 301. The height angle limiting hole 303 is provided on the side of the circular gear 302, and several are arranged in a circle at equal angles. The gear set is freely meshed when the photovoltaic panel 1 is generating electricity normally. In the event of strong winds, one end of the height limiting rod 6 is in the through hole of the azimuth rotating rod 5, and the other end is embedded in the height angle limiting hole 303, thereby fixing the rotation angle of the height shaft 4.

[0033] To ensure better retraction of the height limiting rod 6, an elastic component is also included. This elastic component comprises a first fixed hook 401, a second fixed hook 402, and a spring 403. The first fixed hook 401 is fixedly connected to the azimuth rotating rod 5, and the second fixed hook 402 is fixedly connected to the height limiting rod 6. The spring 403 is connected at both ends to the first fixed hook 401 and the second fixed hook 402, respectively. When the height angle limitation needs to be released, the spring 403 pulls the height limiting rod 6 out of the height angle limiting hole 303. The number of limiting rods 102 and height angle limiting holes 303 can be determined based on factors such as the region, season, and set angle of the photovoltaic power generation installation to ensure optimal protection angle for limiting rotation.

[0034] For the convenience of moving the height limiting rod 6 and the azimuth limiting disc group, further comprising: a base one 501, a driving part one 502, a base two 503 and a driving part two 504, a plurality of base ones 501 are fixedly installed on the support rod 2, the driving part one 502 is installed on each of the base ones 501, and the driving part one 502 is used to push the azimuth sliding assembly to slide up and down, the base two 503 is fixedly installed on the upper end surface of the azimuth shaft 3, the driving part two 504 is installed on the base two 503, and the driving part two 504 is used to push the height limiting rod 6 to be embedded in the gear group, and in the embodiment, the driving part one 502 and the driving part two 504 preferably use push rod motors or air cylinders, and here the push rod motor is taken as an example.

[0035] Working principle: in the photovoltaic power generation process, under normal circumstances, the photovoltaic panel 1 rotates following the movement of sunlight, when encountering strong wind weather, the anemometer 7 is used to detect the wind speed, when reaching the set wind speed interval, the signal is transmitted to the control equipment, the control equipment makes the height shaft 4 and the azimuth shaft 3 of the photovoltaic panel 1 deflect to a smaller angle of wind load. The deflection angle can be set in stages, such as 15° when the wind speed is 15 m / s, 45° when the wind speed is 20 m / s, 60° when the wind speed is 25 m / s, and so on.

[0036] When the azimuth angle deflection is completed, the push rod motor one pushes the azimuth sliding assembly to move upward on the support rod 2, and at the same time, the hollow through hole of the limiting disc one 201 and the limiting disc two 202 is embedded. When the height angle deflection is completed, the push rod motor two pushes the height limiting rod 6 to move to the height angle limiting hole 303, at this time, the azimuth shaft 3 and the height shaft 4 are locked, and the torque and bending moment of the transmission component under strong wind are reduced.

[0037] When the wind speed decreases to the safe wind speed area, the push rod motor one is controlled to retract, the azimuth sliding assembly is lowered, the limiting rod 102 is extracted from the hollow through hole of the limiting disc one 201, the locking state of the azimuth shaft 3 is released, the push rod motor two is controlled to retract, and the spring 403 assembly simultaneously drives the height angle limiting rod to retract in the height angle limiting hole 303, the locking state of the height shaft 4 is released, the photovoltaic panel 1 is reoriented to the sunlight, and normal photovoltaic power generation is realized.

[0038] It should be noted that the above embodiment is only used to illustrate the technical solutions of the present disclosure, not to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, which should be covered in the scope of the claims of the present disclosure.
