Description

Technical Field

[0002] As the global demand for renewable energy continues to increase, solar photovoltaic technology, as one of the important clean energy sources, has received widespread attention and application. Photovoltaic power generation systems are usually composed of photovoltaic modules, support structures and inverters, among which the design of the support structure has an important impact on the overall performance, stability and cost of the photovoltaic system.

[0029] Embodiment 2, on the basis of embodiment 1, as Figure 1-Figure 2 As shown, the lifting mechanism 2 includes: an electric lifting column 201, the electric lifting column 201 is fixedly installed at the top center of the base plate 1, the top movable end of the electric lifting column 201 is fixedly connected to a horizontal plate 202, the horizontal plate 202 is fixedly connected to a pair of vertical sleeves 203 symmetrically on the left and right, a guide rod 204 is slidably provided in the sleeve 203, the guide rod 204 is slidably connected to the inner wall of the sleeve 203 up and down, the bottom end of the guide rod 204 is fixedly connected to the base plate 1, and a distance sensor 205 is fixedly provided at the bottom end of the horizontal plate 202.

[0032] The working principle and beneficial effects of the above technical solution are as follows: when the photovoltaic panel 606 in the photovoltaic support assembly 6 needs to change its height in response to the angle of sunlight and the site environment, the lifting mechanism 2 starts to work, and the controller 7 controls the electric lifting column 201 to quickly and accurately lift to the specified working height. At the same time, the distance sensor 205 works to record the height distance change between the horizontal plate 202 and the bottom plate 1 in real time, and transmits it to the controller 7, so that the controller 7 can adjust the rising height distance. The guide rod 204 is to prevent the sliding direction of the electric lifting column 201 and limit the horizontal motion pair.

[0034] The pitch angle adjustment mechanism 5 includes: the top of the rotating frame 402 is rotatably connected to the rotating shaft 501 in the front-to-back direction, the front end of the rotating shaft 501 is fixedly connected to the vertical rod 1 502, the bottom end of the vertical rod 1 502 is rotatably connected to the transmission shaft 1 503 along the front-to-back direction, the front end of the transmission shaft 1 503 is fixedly connected to the worm gear 504, the top of the worm gear 504 is meshedly connected to the worm 505 along the front-to-back direction, the worm 505 is rotatably connected to the mounting seat 506, the mounting seat 506 is fixedly connected to the front end of the vertical rod 1 502, the left end of the worm 505 is fixedly connected to the output shaft end of the motor 2 507, the motor 2 507 is electrically connected to the second power supply 508, the second power supply 508 is fixedly connected to the top of the mounting seat 506, the rear end of the transmission shaft 1 503 is fixedly connected to the spur gear 2 509, the spur gear 2 509 is meshedly connected to the semicircular gear ring 2 510, the top of the gear ring 2 510 is fixedly connected to the cross bar 511, and the cross bar 511 is fixedly connected to the left and right sides of the rotating frame 402.

[0035] The working principle and beneficial effects of the above technical solution are as follows: when the azimuth angle of the photovoltaic panel 606 in the horizontal direction needs to be adjusted, the azimuth angle adjustment mechanism 4 starts to work, the controller 7 controls the motor 1 404 to operate, the output shaft of the motor 1 404 increases the torque through the reducer 407 to rotate the spur gear 1 406, and the spur gear 1 406 moves in a circle around the disc track 401 and the center of the gear ring 1 408, so that the horizontal plate 2 403 drives the rotating frame 402 to rotate to the target working azimuth angle at the center of the disc track 401, and finally the motor 1 404 stops running;

[0036] When it is necessary to adjust the up and down pitch angle of the photovoltaic panel 606, the pitch angle adjustment mechanism 5 starts to work, and the controller 7 controls the motor 2 507 to run. The motor 2 507 drives the worm 505 to rotate in the mounting seat 506.

The strip grooves 13 on both sides of the front and rear are slidably hinged to sliding rods 14. The other ends of the sliding rods 14 are hinged to the front and rear walls of the box body 801 on their respective sides. The sliding rod 14 is fixedly connected to a strip groove 2 15. A cross bar 511 is slidably hinged in the strip groove 2 15. The cross bar 511 is fixedly connected to a clamping block 2 18 near the rotating frame 402 side. The clamping block 17 and the clamping block 2 18 are both arc-shaped clamping blocks. The clamping block 17 and the clamping block 2 18 are fixedly connected to a number of rubber blocks 19 near the rotating frame 402 side.

[0040] The slider 10 is symmetrically provided with two groups of anti-reverse sliding mechanisms 20 front and back, and the anti-reverse sliding mechanism 20 on the left front side includes: a plurality of ratchet teeth 21, a plurality of ratchet teeth 21 are fixedly provided at the front end of the left slider 10 along the front and rear direction, an L-shaped bracket 22 is fixedly connected to the rear side of the front wall of the box body 801, a plurality of barbs 23 are hingedly connected on the L-shaped bracket 22 along the left and right directions, the ratchet teeth 21 press the barbs 23 at the corresponding positions, the front ends of the barbs 23 are hingedly connected to a slide bar 24 along the left and right directions, a spring 25 is fixedly connected between the left end of the slide bar 24 and the side wall of the box body 801, the front wall of the box body 801 is provided with left and right sliding cavities 26, an electromagnet 27 is fixedly installed at the left end of the sliding cavity 26, an armature block 28 is connected to the sliding cavity 26 for left and right sliding, a connecting rod 29 is hingedly connected between the armature block 28 and the slide bar 24, and the connecting rod 29 slides left and right and passes through the front wall of the box body 801.

[0041] The working principle and beneficial effects of the above technical solution are as follows: when encountering strong winds and the wind force level is high, in order to prevent the angle adjustment mechanism 3 from stalling and rotating at a horizontal angle due to excessive wind force, the windproof brake stabilization mechanism 8 starts to work, and the controller 7 controls a pair of motors 3 802 on the left and right sides of the box body 1 801 to run synchronously, and the motors 3 802 drive the threaded rods 12 on their respective sides to rotate in the internal threaded tube 11, thereby pushing the sliders 10 and the clamping blocks 17 on the left and right sides to move closer to the center, until the clamping blocks 17 on the left and right sides are tightly attached to the bottom cylindrical surface of the rotating frame 402, and at the same time At the same time, the sliding of the slider 10 causes the sliding rod 14 in the strip groove 13 and the strip groove 2 15 to rotate synchronously around the point of hinge with the side wall of the box body and move closer to the center, that is, the movable end of the sliding rod 14 slides in the strip groove 13 toward the threaded rod 12, and the strip grooves 13 on the left and right sides drive the cross bar 511 and the clamping block 2 18 to move closer to the rotating frame 402, and the clamping block 17 and the several rubber blocks 19 on the clamping block 2 18 increase the friction force, and finally the rotating frame 402 stops rotating and stabilizes the position, and then the motor 3 802 stops working; the anti-reverse sliding mechanism 20 works to To prevent the left and right sliders 10 from sliding in the opposite direction and thus being unable to brake and stabilize the horizontal angle of the rotating frame 402, while the slider 10 slides, the ratchet teeth 21 on the slider 10 and the barbs 23 fit in turn toward the center side. When the slider 10 stops sliding, the spring 25 presses the slide bar 24 toward the center. The slide bar 24 slides in the sliding cavity 26, allowing the barbs 23 to rotate around the contact point with the L-shaped bracket 22. The ratchet teeth 21 are locked by the lever principle, so that the left and right sliders cannot slide in the opposite direction. When the wind force decreases and the angle of the rotating frame 402 needs to be adjusted, The controller 7 controls the operation of the electromagnet, and the electromagnet 27 attracts the armature block 28 and the connecting rod 29 to slide synchronously in the direction away from the center hole 9, and the connecting rod 29 drives the slide bar 24 to slide synchronously in the direction away from the center hole 9, so that the plurality of barbs 23 rotate in the opposite direction and cannot lock the ratchet 21, thereby causing the slider 10 to slide in the opposite direction. The windproof braking stabilizing mechanism 8 is beneficial for the adjustable supporting structure to adapt to windy weather and prevent rotation due to excessive wind force. The anti-reverse sliding mechanism 20 increases the braking stabilizing ability of the windproof braking stabilizing mechanism 8 and can quickly lock the position of the slider 10 after one-way sliding.
