Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment and discloses a dual-axis photovoltaic bracket with sun tracking function. Background Art

[0002] The dual-axis photovoltaic support uses advanced control systems and sensors to track the position of the sun in real time. By rotating in both horizontal and vertical directions, that is, tracking the azimuth and altitude of the sun, the photovoltaic panels are always kept within the optimal angle range of sunlight, thereby improving the efficiency of photovoltaic power generation.

[0003] The dual-axis photovoltaic bracket uses sensors to detect the position of the sun and light intensity information. Common sensors include light sensors and position sensors, which provide data support for the control system to accurately control the tracking angle of the photovoltaic panel.

[0004] Of course, in the existing technology, photovoltaic panels are moved at an angle by electric push rods, so that they can track the sun. Since photovoltaic panels are usually installed outdoors in a flat shape, when the outdoor wind is strong, the photovoltaic panels are easily tilted by the wind, which in turn causes the entire photovoltaic panel bracket to easily tilt, causing the upper photovoltaic panel of the dual-axis photovoltaic bracket to easily tilt during the sun tracking process, and thus making the dual-axis photovoltaic bracket unable to increase the stability of the photovoltaic panel when blown by the wind. Summary of the Invention

[0005] In response to the defects in the existing technology, the dual-axis photovoltaic bracket with solar tracking provided by the present invention can increase the stability of the photovoltaic panel during the solar tracking process and avoid the situation where the photovoltaic panel is easily tipped over during the solar tracking process.

[0006] In order to solve the above technical problems, the present invention proposes the following technical solutions: a dual-axis photovoltaic bracket with solar tracking, comprising a base, a main electric push rod is provided on one side of the upper end of the base, the upper end of the main electric push rod is slidably connected to the bracket, the lower end of the bracket is hinged with a hinge at the junction with the base, a bearing passes through one side of the upper end of the bracket, a sleeve is mounted on the outer side of the bearing, one end of the sleeve is swingably connected to a lining plate, one side of the lining plate is swingably connected to a photovoltaic panel, and a sensor is provided on the other side of the upper end of the bracket.

[0007] Furthermore, the base is installed as a whole on the ground, and a control panel is provided on one side of the base. The control panel is connected to the photovoltaic panel circuit through a power line, and the sensor and the main electric push rod are connected to the control panel circuit through wires. The sensor adopts a light sensor.

[0008] Furthermore, the hinge is located in the middle of the lower end of the bracket, and the main electric push rod drives one end of the bracket to tilt and swing in the vertical direction. At this time, the bracket and the photovoltaic panel as a whole tilt and swing in the vertical direction through the hinge.

[0009] Furthermore, the bearing is in the shape of a workpiece when viewed from above, and the bearing is arranged horizontally as a whole. The sleeve slides horizontally on the outside of the bearing, and at the same time, the sleeve swings vertically on the outside of the bearing.

[0010] Furthermore, the photovoltaic panel is connected to the bracket through a lining plate, a sleeve and a bearing, and the photovoltaic panel as a whole tilts and swings in a horizontal direction.

[0011] Furthermore, a side electric push rod is provided at the end of the bracket away from the bearing, a slider is provided at the upper end of the side electric push rod, a track is provided on the side of the photovoltaic panel close to the side electric push rod, the slider is inside the track, and retaining rings are provided on both sides of the track. Shrapnel are embedded on both sides of the slider close to the retaining ring, and the end of the shrapnel away from the slider is slidably connected to a sliding frame.

[0012] Furthermore, the side electric push rod and the main electric push rod are arranged in a vertical direction, and the side electric push rod is connected to the control panel circuit through an electric wire.

[0013] Furthermore, the upper and lower ends of the slider fit into the inside of the track. When the side electric push rod slides upward, the side electric push rod drives the entire track to tilt upward through the slider, thereby facilitating the overall tilt and swing of the photovoltaic panel in the vertical direction.

[0014] Furthermore, a slide groove is passed through both sides of the clamping ring, and the slide groove is arranged in an arc shape with an arc angle of 180°. The sliding frame is located inside the clamping ring, and the clamping ring is arranged vertically inside the track.

[0015] Furthermore, the spring pieces have a thickness of 0.3-0.5 cm, are arranged horizontally inside the track, and are made of a deformable and resilient metal material, such as spring steel.

[0016] Furthermore, when the outdoor wind is strong, the photovoltaic panel as a whole shakes horizontally, the track and the retaining ring at one end of the photovoltaic panel slide horizontally, the slider is in a stationary state, and the lining plate and sleeve at the other end of the photovoltaic panel slide horizontally on the outside of the bearing.

[0017] It can be seen from the above technical solution that the beneficial effects of the present invention are:

[0018] The sensor of the present invention senses the direction of light and transmits the signal to the control panel. The control panel controls the operation of the main electric push rod. The main electric push rod is pushed to one end of the bracket. The bracket as a whole is hinged to the upper end of the base and tilts and swings in the vertical direction. At this time, the bearing, sleeve and liner are driven by the bracket to tilt and swing in the vertical direction, while the sleeve cannot rotate outside the bearing.

[0019] When the outdoor wind is strong, the photovoltaic panel of the present invention shakes horizontally as a whole, the track and the clamping ring at one end of the photovoltaic panel slide horizontally, the slider is in a stationary state, and the liner and sleeve at the other end of the photovoltaic panel slide horizontally on the outside of the bearing. When the sliding arc of the clamping ring is small, the sliding frame is in a stationary state.

[0020] When the sliding arc of the clamping ring is large, the clamping ring slides and is squeezed to one end of the sliding frame, and the sliding frame is squeezed to one end of the spring sheet. The sliding frame and the slider form an extrusion on the spring sheet, and the spring sheet is deformed in the vertical direction. When the deformation arc of the spring sheet reaches the inner wall of the track, the inner wall of the track forms a return extrusion on the spring sheet, and then the spring sheet uses its rebound elasticity to assist the sliding frame and the clamping ring to return, and assist the track and the photovoltaic panel to return, so as to avoid the existing photovoltaic panel from easily tipping over after being blown by wind, increase the stability of the photovoltaic panel when tracking the direction of sunlight, and avoid affecting the overall stability of the photovoltaic panel due to strong outdoor wind.

The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0032] Reference Figure 1-7 A dual-axis photovoltaic bracket with solar tracking includes a base 1, a main electric push rod 101 is provided on one side of the upper end of the base 1, the upper end of the main electric push rod 101 is slidably connected to a bracket 102, a hinge 104 is hinged at the junction of the lower end of the bracket 102 and the base 1, a bearing 2 is passed through one side of the upper end of the bracket 102, a sleeve 201 is sleeved on the outer side of the bearing 2, one end of the sleeve 201 is swingably connected to a lining plate 202, one side of the lining plate 202 is swingably connected to a photovoltaic panel 103, and a sensor 105 is provided on the other side of the upper end of the bracket 102;

[0033] The base 1 is installed on the ground as a whole. A control panel is provided on one side of the base 1. The control panel is connected to the photovoltaic panel 103 circuit via a power line. The sensor 105 and the main electric push rod 101 are both connected to the control panel circuit via wires. The sensor 105 is a light sensor.

[0034] The hinge 104 is located in the middle of the lower end of the bracket 102. The main electric push rod 101 drives one end of the bracket 102 to tilt and swing in the vertical direction. At this time, the bracket 102 and the photovoltaic panel 103 are tilted and swing in the vertical direction as a whole through the hinge 104.

[0035] The bearing 2 is in the shape of a workpiece when viewed from above. The bearing 2 is arranged horizontally as a whole. The sleeve 201 slides horizontally on the outside of the bearing 2. At the same time, the sleeve 201 swings vertically on the outside of the bearing 2. Please refer to the attached manual for details. Figure 3 As shown;

[0036] By providing the lining plate 202 and the sleeve 201, when the end of the photovoltaic panel 103 away from the lining plate 202 is tilted and moved in a vertical direction, the photovoltaic panel 103 can be tilted and swung in a vertical direction through the lining plate 202 and the sleeve 201, thereby facilitating the change of the overall direction of the photovoltaic panel 103;

[0037] The photovoltaic panel 103 is connected to the bracket 102 through the lining plate 202, the sleeve 201 and the bearing 2, and the photovoltaic panel 103 as a whole tilts and swings in the horizontal direction;

[0038] The main electric push rod 101 is pushed to one end of the bracket 102, and the bracket 102 as a whole is tilted and swung vertically at the upper end of the base 1 through the hinge 104, so that the photovoltaic panel 103 can be turned according to the sunlight, thereby achieving the effect of sun tracking;

[0039] Refer to the instruction manual Figure 2-7 In this embodiment, a side electric push rod 3 is provided at the end of the bracket 102 away from the bearing 2, a slider 301 is provided at the upper end of the side electric push rod 3, a track 4 is provided on the side of the photovoltaic panel 103 close to the side electric push rod 3, the slider 301 is located inside the track 4, a retaining ring 4 is provided on both sides of the track 4, and spring pieces 302 are embedded on both sides of the slider 301 close to the retaining ring 4, and the end of the spring piece 302 away from the slider 301 is slidably connected to the sliding frame 303;

[0040] The side electric push rod 3 and the main electric push rod 101 are arranged in a vertical direction, and the side electric push rod 3 is connected to the control panel circuit through an electric wire;

[0041] The upper and lower ends of the slider 301 fit in the inside of the track 4. When the side electric push rod 3 slides upward, the side electric push rod 3 drives the track 4 to tilt upward through the slider 301, thereby facilitating the photovoltaic panel 103 to tilt and swing vertically as a whole.

[0042] When the outdoor wind is strong, the side track 4 of the photovoltaic panel 103 slides horizontally as a whole, and the sleeve 201 at the other end of the photovoltaic panel 103 slides horizontally on the outside of the bearing 2. At this time, the slider 301 is in a stationary state;

[0043] There are slide grooves on both sides of the snap ring 401. The slide grooves are arranged in an arc shape with an arc angle of 180 degrees. The sliding frame 303 is inside the snap ring 401. The snap ring 401 is arranged vertically inside the track 4. Figure 6 As shown;

[0044] The internal sliding groove of the snap ring 401 is arranged in an arc shape. When the snap ring 401 slides in the horizontal direction, the snap ring 401 can drive the sliding frame 303 to slide synchronously, and then the sliding frame 303 can be squeezed to one end of the spring piece 302, and the spring piece 302 is bent and deformed in an arc shape as a whole;

[0045] The spring piece 302 has a thickness of 0.3-0.5 cm and is arranged horizontally inside the track 4. The spring piece 302 is made of a deformable and resilient metal material, such as spring steel.

[0046] When the spring piece 302 is not deformed, the spring piece 302 is arranged in a horizontal direction as a whole. After the spring piece 302 is deformed, the spring piece 302 is bent in a vertical arc shape as a whole.

[0047] When the outdoor wind is strong, the photovoltaic panel 103 as a whole sways horizontally, the track 4 and the retaining ring 401 at one end of the photovoltaic panel 103 slide horizontally, the slider 301 is in a stationary state, and the liner 202 and the sleeve 201 at the other end of the photovoltaic panel 103 slide horizontally on the outside of the bearing 2. When the sliding arc of the retaining ring 401 is small, the sliding frame 303 is in a stationary state;

[0048] When the sliding arc of the snap ring 401 is large, the snap ring 401 slides and is squeezed to one end of the sliding frame 303, and the sliding frame 303 is squeezed to one end of the spring piece 302. The sliding frame 303 and the slider 301 squeeze the spring piece 302, and the spring piece 302 is deformed in the vertical direction. When the spring piece 302 is deformed to the inner wall of the track 4, the inner wall of the track 4 forms a return squeeze on the spring piece 302, and then the spring piece 302 uses its resilience to assist the sliding frame 303 and the snap ring 401 to return to their original position, and assist the track 4 and the photovoltaic panel 103 to return to their original position, thereby preventing the existing photovoltaic panel 103 from easily tipping over after being blown by wind, increasing the stability of the photovoltaic panel 103 when tracking the direction of sunlight, and preventing the overall stability of the photovoltaic panel 103 from being affected by strong outdoor wind.

[0049] Working principle: The sensor 105 senses the direction of light and transmits the signal to the control panel. The control panel controls the operation of the main electric push rod 101. The main electric push rod 101 is pushed to one end of the bracket 102. The bracket 102 as a whole tilts and swings vertically at the upper end of the base 1 through the hinge 104. At this time, the bearing 2, sleeve 201 and liner 202 as a whole are driven by the bracket 102 to tilt and swing vertically, while the sleeve 201 cannot rotate outside the bearing 2.

[0050] When the sensor 105 detects sunlight, the control panel controls the side electric push rod 3 to move upward or downward, and the side electric push rod 3 drives the track 4 to tilt in the vertical direction through the slider 301, and then the track 4 drives the photovoltaic panel 103 to tilt in the vertical direction. The other end of the photovoltaic panel 103 uses the bearing 2 as a fulcrum, and the photovoltaic panel 103 is tilted and swung in the vertical direction at one end of the bearing 2 through the lining plate 202 and the sleeve 201, so that the photovoltaic panel 103 can change its direction according to the direction of sunlight;

[0051] When the wind is strong outdoors, the photovoltaic panel 103 shakes horizontally as a whole, the track 4 and the snap ring 401 at one end of the photovoltaic panel 103 slide horizontally, the slider 301 is in a stationary state, and the liner 202 and the sleeve 201 at the other end of the photovoltaic panel 103 slide horizontally on the outside of the bearing 2. When the sliding arc of the snap ring 401 is small, the sliding frame 303 is in a stationary state. When the sliding arc of the snap ring 401 is large, the snap ring 401 slides and squeezes to one end of the sliding frame 303, and the sliding frame 303 squeezes to one end of the spring piece 302. The sliding frame 303 and the slider 301 squeeze the spring piece 302, and the spring piece 302 is deformed in the vertical direction. When the spring piece 302 is deformed to the inner wall of the track 4, the inner wall of the track 4 squeezes the spring piece 302 to return to its original position, and then the spring piece 302 uses its rebound elasticity to assist the sliding frame 303 and the snap ring 401 to return to their original position, thereby assisting the track 4 and the photovoltaic panel 103 to return to their original position.
