Description

Technical Field

[0001] This utility model relates to a photovoltaic support base, specifically an adjustable photovoltaic support base. Background Technology

[0002] Photovoltaics, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes: stand-alone operation and grid-connected operation. Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel, and need to be installed on a base when using photovoltaic brackets.

[0003] The photovoltaic support base is a fundamental component of the photovoltaic support system, mainly used to stably fix the entire photovoltaic support and solar panels to the ground, roof or other supporting surfaces.

[0004] Currently, adjustable photovoltaic support bases mainly achieve angle adjustment through screw drive and worm gear, gear rack and chain drive, and bolt fixing, thereby adjusting the orientation and angle of the solar panels. However, after adjusting the elevation angle of the solar panels, the overall center of gravity of the photovoltaic support base will be too high. In strong winds, the windward area of ​​the solar panels is large, which can easily generate huge wind loads, potentially causing the support to deform, bolts to break, or even the entire support to overturn.

[0005] After adjusting the orientation and angle of the solar panels, the existing adjustable photovoltaic support base has a relatively high center of gravity. In strong winds, the large windward area of ​​the solar panels can easily generate huge wind loads, which may lead to deformation of the support, bolt breakage, or even complete overturning. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable photovoltaic support base to solve the problem mentioned in the background art that after adjusting the orientation and angle of the solar panel, the overall center of gravity of the photovoltaic support base is too high. In strong winds, the windward area of ​​the solar panel is large, which can easily generate huge wind loads, potentially leading to deformation of the support, bolt breakage, or even the entire structure overturning.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable photovoltaic bracket base includes a base body, a bracket body for mounting photovoltaic panels is rotatably mounted on the top of the base body, a support seat is provided on the top of the base body, a sliding groove is provided on the bracket body, a guide component is provided in the support seat, and an adjustment mechanism for adjusting the angle of the bracket body is provided on the guide component.

[0009] The adjustment mechanism includes a locking component for fixing the angle position of the support body and a wind-triggered mechanism. The wind-triggered mechanism is located on one side of the support body, and a fixing mechanism is provided inside the support base.

[0010] The adjustable photovoltaic bracket base as described above: the guide assembly includes two toothed plates slidably mounted in the support base and a return spring disposed on one side of the toothed plates. Anti-slip pads are provided on both sides of the toothed plates for anti-slip purposes, and square grooves are provided on both sides of the top of the support base.

[0011] The adjustable photovoltaic bracket base as described above: the fixing mechanism includes two mounting blocks respectively fixed to one side of the toothed plate and a beveled locking block slidably mounted on one side of the mounting blocks. The two mounting blocks respectively cooperate with two square grooves. A reset cover plate is slidably mounted on the top of the support base. The reset cover plate is in a pressing fit with the two beveled locking blocks.

[0012] The adjustable photovoltaic bracket base as described above: the locking assembly includes a lifting platform slidably installed in the support base and a drive wheel set disposed on the lifting platform for driving the lifting platform to move up and down in the support base, and a groove is provided in the lifting platform.

[0013] The adjustable photovoltaic support base as described above: the wind triggering mechanism includes a cylinder slidably mounted on the slide groove and a pressing block rotatably mounted on the other end of the cylinder. The pressing block slides on a square frame set on one side of the lifting platform. Two beveled blocks are slidably mounted inside the square frame. The pressing block and the two beveled blocks are in a pressing fit.

[0014] The adjustable photovoltaic support base as described above: a square tube is provided on one side of the two toothed plates, and two beveled blocks are slidably installed on the square tube respectively.

[0015] The adjustable photovoltaic bracket base as described above: the locking assembly further includes a compression spring disposed on the groove and limit blocks disposed on both sides of the compression spring. Both limit blocks are slidably installed in the groove, and the two limit blocks respectively cooperate with two toothed plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] During normal operation, the photovoltaic bracket is rotated by the lifting platform to adjust the elevation angle of the photovoltaic bracket. When the wind speed exceeds the standard, the photovoltaic bracket is subjected to force by the wind-triggered mechanism, which makes the photovoltaic bracket quickly adjust to the flat state. This can effectively reduce the windward area of ​​the photovoltaic panel and the wind direction, reduce the force of the wind on the bracket, and avoid damage to the photovoltaic panel or the bracket structure due to strong wind.

[0018] This utility model also enables the automatic adjustment of the photovoltaic bracket's elevation angle through a lifting platform and locking components, eliminating the need for manual adjustment of the photovoltaic bracket's angle, while also satisfying the advantages of high transmission efficiency and high reliability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figures 1-11 As an embodiment of the present utility model, the adjustable photovoltaic bracket base includes a base body 1, a bracket body 2 for mounting photovoltaic panels is rotatably mounted on the top of the base body 1, a support seat 3 is provided on the top of the base body 1, a sliding groove 10 is provided on the bracket body 2, a guide component and an adjustment mechanism for adjusting the angle of the bracket body 2 are provided in the support seat 3.

[0033] The adjustment mechanism includes a locking component for fixing the angle position of the support body 2 and a wind-triggered mechanism. The wind-triggered mechanism is located on one side of the support body 2, and a fixing mechanism is provided inside the support base 3.

[0034] In this embodiment, during normal operation, the bracket body 2 is rotated by the adjustment mechanism to adjust the elevation angle of the bracket body 2. When the wind speed exceeds the standard, the bracket body 2 is subjected to pressure. At the same time, the bracket body 2 cooperates with the wind triggering mechanism to quickly adjust the photovoltaic bracket to a flat state. This can effectively reduce the windward area of ​​the photovoltaic panel and the wind direction, reduce the force of the wind on the bracket, and avoid damage to the photovoltaic panel or the bracket structure due to strong wind.

[0035] As a further embodiment of this utility model, the guide assembly includes two toothed plates 4 slidably mounted in the support base 3 and a return spring 5 disposed on one side of the toothed plates 4. Anti-slip pads are provided on both sides of the toothed plates 4 for anti-slip purposes, and square grooves 19 are provided on both sides of the top of the support base 3.

[0036] In this embodiment, the two toothed plates 4 are designed symmetrically, and the return spring 5 can elastically reset the two toothed plates 4.

[0037] As a further embodiment of this utility model, the fixing mechanism includes two mounting blocks 7 respectively fixed to one side of the toothed plate 4 and a slanted edge locking block 8 slidably mounted on one side of the mounting blocks 7. The two mounting blocks 7 respectively cooperate with two square grooves 19. A reset cover plate 9 is slidably mounted on the top of the support base 3. The reset cover plate 9 is in a pressing fit with the two slanted edge locking blocks 8.

[0038] In this embodiment, a beveled locking block 8 is slidably mounted on one side of the mounting block 7. A spring for elastically resetting the beveled locking block 8 is provided between the beveled locking block 8 and the mounting block 7. The mounting block 7 is slidably engaged with the square groove 19. By pressing down on the reset cover plate 9, the two beveled locking blocks 8 can be squeezed downwards.

[0039] As a further embodiment of this utility model, the locking assembly includes a lifting platform 15 slidably installed in the support base 3 and a drive wheel set 16 disposed on the lifting platform 15 for driving the lifting platform 15 to move up and down in the support base 3, and the lifting platform 15 is provided with a groove.

[0040] In this embodiment, the support base 3 is provided with a guide column, the lifting platform 15 slides on the guide column, and the lifting platform 15 is provided with a groove.

[0041] As a further embodiment of this utility model, the wind-powered triggering mechanism includes a cylinder 11 slidably mounted on the slide groove 10 and a pressing block 12 rotatably mounted on the other end of the cylinder 11. The pressing block 12 slides on a square frame 13 located on one side of the lifting platform 15. Two angled blocks 14 are slidably mounted inside the square frame 13, and the pressing block 12 and the two angled blocks 14 are in a pressing fit.

[0042] In this embodiment, the cylinder 11 slides on the groove 10 on the side of the bracket body 2, the cylinder 11 is rotatably mounted on the extrusion block 12, the extrusion block 12 is slidably mounted on the square frame 13, and the extrusion block 12 and the two beveled blocks 14 are in an up-and-down extrusion fit.

[0043] As a further embodiment of this utility model, a square tube 6 is provided on one side of the two toothed plates 4, and two oblique blocks 14 are slidably installed on the square tube 6 respectively.

[0044] In this embodiment, the beveled block 14 slides on the square tube 6, and when the beveled block 14 moves, it can drive the toothed plate 4 to move through the square tube 6.

[0045] As a further embodiment of this utility model, the locking assembly also includes a compression spring 17 disposed on the groove and limiting blocks 18 disposed on both sides of the compression spring 17. Both limiting blocks 18 are slidably installed in the groove, and the two limiting blocks 18 respectively cooperate with the two toothed plates 4.

[0046] In this embodiment, when the support body 2 needs to be adjusted, the drive wheel set 16 on the lifting platform 15 rotates up and down on the anti-slip pads on the two toothed plates 4, thereby driving the lifting platform 15 to move upward. At the same time, the two limiting blocks 18 inside it will continuously contact the inner teeth of the toothed plates 4. When the lifting platform 15 moves upward, the inclined sides of the two limiting blocks 18 will fit against the inclined teeth on the inner side of the toothed plates 4. Then, the lifting platform 15 moves upward, causing the two limiting blocks 18 to receive pressure and move inward, compressing the compression spring 17. When the support body 2 is adjusted to a suitable angle, the lifting platform 15 is controlled to stop moving. At this time, the right-angled sides of the two limiting blocks 18 fit against the right-angled sides of the inclined teeth of the toothed plates 4, thereby keeping the lifting platform 15 in the current position, thereby realizing the adjustment of the elevation angle of the support body 2.

[0047] When the wind speed exceeds the limit and the photovoltaic support is subjected to pressure, the wind will cause the support body 2 to rotate backward a certain distance. At this time, the support body 2 will drive the pressing block 12 to move downward through the cylinder 11. The pressing block 12 will then press the two inclined blocks 14 below to both sides, causing the two inclined blocks 14 to slide to both sides. At the same time, the two inclined blocks 14 will drive the two toothed plates 4 to move to both sides, compressing the return spring 5. At this time, the inclined edge locking block 8 on one side of the two toothed plates 4 meets the square groove 19, compressing the inclined edge locking block 8, so that the inclined edge locking block 8 and the mounting block... The end of 7 passes through the square groove 19, and then the spring inside the mounting block 7 immediately pops out to drive the inclined side locking block 8 to reset, thereby fixing the position of the two toothed plates 4 and keeping the two toothed plates 4 in an outward-opening state. At this time, when the toothed plates 4 on both sides of the lifting platform 15 leave, they will immediately lose support, and the lifting platform 15 will quickly descend, thereby driving the photovoltaic bracket to quickly adjust to a flat state. When the weather returns to normal, pressing down the reset cover plate 9 can squeeze the two inclined side locking blocks 8 downward, and then multiple reset springs 5 ​​will drive the two toothed plates 4 to quickly reset, thus returning to the initial state.

[0048] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
