Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and specifically proposes an adjustable photovoltaic support for highways. Background Technology

[0002] In temporary construction scenarios along highways, photovoltaic power generation is used due to its economic efficiency and flexibility. Photovoltaic panels need to be fixed and installed using photovoltaic brackets and their angles adjusted. However, the power consumption for construction along the road is characterized by high frequency of transfer and complex site environment, which puts forward comprehensive requirements for the temporary fixation, environmental adaptability and portability of photovoltaic brackets.

[0003] Currently, photovoltaic support structures used in conjunction with temporary construction generally have limited functionality and are unable to meet the above comprehensive requirements. Specifically, this is reflected in the following aspects:

[0004] 1. Most supports simply use sandbags, stones and other heavy objects to press directly onto the ground, lacking a reinforcement structure that forms an integral part of the support; the counterweights and supports are in contact but actually separated, which cannot effectively resist lateral slippage and upward pull, especially on sloping shoulders or in strong winds, making them prone to slippage, overturning or even collapse.

[0005] 2. The continuous vibrations generated by the frequent operation of large machinery at the construction site will be directly transmitted to the photovoltaic panels, causing the support frame to slip, the connectors to loosen, and even the internal structure of the photovoltaic panels to be damaged due to long-term fatigue stress, which seriously affects the power generation stability and equipment life.

[0006] 3. Photovoltaic panels have a large wind-exposed area, and existing temporary support structures lack a buffering and absorption mechanism for wind loads, making them prone to violent shaking or overall displacement under strong gusts of wind.

[0007] 4. Most existing supports are integral welded rigid fixed structures, which are large in size and cannot be quickly folded into a regular and compact form. Frequent handling causes problems such as inconvenience in moving, transporting and placing, and taking up a lot of transportation space. They are also prone to damage to the support components and collisions with people.

[0008] In summary, existing photovoltaic (PV) brackets used for temporary construction on highways have limited structural functionality and suffer from a significant inability to simultaneously fulfill multiple functions. For instance, increasing their weight to improve placement stability complicates relocation and transportation. While rigid structural designs ensure overall strength, they fail to meet the requirements for portable transport. Therefore, current technology lacks a PV bracket that can achieve a balance between effective temporary fixation, vibration and wind resistance, and convenient storage, while also allowing for flexible switching between use and handling. Summary of the Invention

[0009] To address the aforementioned problems, this invention provides an adjustable photovoltaic support for highways, which solves the problems mentioned in the background section.

[0010] To achieve the above objectives, the present invention employs the following technical solution: an adjustable photovoltaic bracket for highways, comprising a base frame, an anchoring base, a buffer base, a fixed support plate, and an inclined support; the base frame is a rectangular frame with open top and bottom; the anchoring base includes a base plate that is detachably and horizontally installed within the base frame and an anchor rod mechanism assembled at the bottom end of the base plate, the anchor rod mechanism being an expandable structure, capable of being inserted and anchored to the ground when expanded; the buffer base is located above the base plate and is slidably embedded within the base frame for lateral and vertical buffering; the buffer base is provided with a storage mode and a usage mode; the fixed support plate is used to fix and place photovoltaic panels, one end of which is hinged to the top of the buffer base; the inclined support is hinged to the top of the buffer base for tilting and supporting the fixed support plate and adjusting the support angle.

[0011] When the bottom of the buffer base contacts the base plate, it is in storage mode. When the fixed support plate is horizontal, the buffer base, fixed support plate, and diagonal support can be stored together in the base frame. A locking structure is provided between the buffer base and the base frame in the vertical direction. When the buffer base slides up and locks with the base frame through the locking structure, it switches to the use mode. The fixed support plate rises to the outside of the base frame, the buffer base is in a buffer state, and the base frame is divided into a counterweight cavity by the base plate and the buffer base. This cavity is used to fill counterweight material to form an integrated counterweight. After the counterweight material is filled into the counterweight cavity, a support layer is formed between the buffer base and the base plate to provide upper and lower support.

[0012] Preferably, the buffer base includes a support frame that is slidably embedded in the base frame, and a base frame is horizontally arranged above the support frame; the base frame and the support frame are vertically elastically connected; a buffer enclosure is fixed to the inner wall of the base frame, and in the use mode, the buffer enclosure is in elastic contact with the four sides of the base frame; the fixed plate and the diagonal support are both hinged to the top of the base frame.

[0013] Preferably, both the support frame and the base frame have rectangular windows, and an elastic support pad is fixed between the support frame and the base frame, with the pad surrounding the rectangular windows of both the support frame and the base frame.

[0014] Preferably, the anchor bolt mechanism includes multiple horizontally rotatable rotating shafts mounted on the bottom end of the base plate, and multiple anchor bolts are fixed on each rotating shaft; when the anchor bolt mechanism is deployed, the anchor bolts are vertically downward.

[0015] Preferably, the bottom end of the base plate is horizontally slidably mounted with a movable rod that corresponds one-to-one with the flipping shaft, and at least one connecting rod is hinged between the flipping shaft and the corresponding movable rod.

[0016] Preferably, bearing plates are fixed at both ends of the base plate, and a bidirectional lead screw is horizontally rotatably installed between the two bearing plates. Multiple moving rods are divided into two groups of corresponding threaded connections on the two threaded sections of the bidirectional lead screw.

[0017] Preferably, the bottom end of the fixed support plate is fixed with two slide rails that are perpendicular to their hinge axes. The inclined support includes a support frame with one end hinged to the top of the base frame, and the other end of the support frame is hinged with a sliding hinge block that corresponds to and slides with the slide rails.

[0018] Preferably, the slide rail has a plurality of pin holes arranged horizontally along its extension direction, and the sliding hinge block is fixed in place with the pin holes.

[0019] Preferably, both bearing plates are positioned by pin insertion with the base frame.

[0020] Preferably, the base frame has pins at the four corners at its bottom.

[0021] The above technical solution has the following advantages or beneficial effects: 1. The present invention provides an adjustable photovoltaic support for highways. On the one hand, by anchoring the base to the ground and using the base frame to assist in inserting it into the ground, the pull-out resistance between the base and the ground is enhanced. On the other hand, by switching the use mode of the buffer base, the counterweight cavity is filled with counterweight material to form an integrated counterweight with the support, thereby lowering the center of gravity. The filling layer after the counterweight cavity is filled with counterweight material constitutes substantial support between the base plate and the support frame, enhancing the integrated support strength. Therefore, the combination of anchoring and counterweight strengthens the stability of the temporary fixation of the support, fundamentally suppressing slippage and overturning.

[0022] 2. This invention provides an adjustable photovoltaic support for highways. By switching the usage mode of the buffer base to the buffer state, multi-directional and multi-dimensional buffering is achieved through the vertical elastic support composed of damping springs and isolation pads and the lateral elastic support of the buffer barrier. It can block, isolate and weaken ground vibrations, and absorb and weaken the impact of strong winds, providing overall protection for the photovoltaic support and photovoltaic panels.

[0023] 3. This invention provides an adjustable photovoltaic support for highways, with a dual-mode switching buffer base that allows for flexible switching during use and transport. When switched to storage mode, and with the anchor mechanism retracted, the entire structure can be stored inside the base frame. The structure is compact and neat, facilitating handling and transportation, reducing space occupation, and protecting the support structure while also preventing bumps and knocks to people.

[0024] 4. In summary, the adjustable photovoltaic bracket for highways provided by the present invention, through the combination of anchoring, counterweight, multi-dimensional elastic buffering and dual-mode switching, has the integrated multi-functional effects of high stability for temporary use, vibration and wind resistance, and convenient storage and portability. The multi-functional integration takes into account the needs of both use and transportation, making it easier to flexibly switch between the two states. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, an adjustable photovoltaic bracket for highways includes a base frame 1, an anchor base 2, a buffer base 3, a fixed support plate 4, and an inclined support 5. The buffer base 3 and the anchor base 2 are installed vertically inside the base frame 1. One end of the fixed support plate 4 is hinged to the top of the buffer base 3 and is used to fix the photovoltaic panel. The inclined support 5 is hinged to the top of the buffer base 3 and is used to tilt the fixed support plate 4 and adjust the support angle.

[0036] like Figure 1 and Figure 2 As shown, the base frame 1 has a rectangular frame structure that is open at the top and bottom, and can be placed directly on the ground in the temporary construction area next to the highway. The bottom of the base frame 1 is provided with four corners with pins 11. The pins 11 have a chamfered structure at two corners. The base frame 1 can be inserted into the ground through the four pins 11 to enhance the stability of the base frame 1.

[0037] like Figure 2 and Figure 3 As shown, the anchoring base 2 includes a base plate 21, on which two corresponding sides are L-shaped flanged and bent structures, with the two flanged and bent structures facing downwards and symmetrically arranged; bearing plates 22 are welded to the other two corresponding sides of the base plate 21. The base plate 21 contacts the inner wall of the base frame 1 through the flanged and bent structures and the bearing plates 22. Two insertion holes are opened on the bearing plates 22. On the side wall of the base frame 1 that contacts the two bearing plates 22, there are pin holes 12 that correspond one-to-one with the insertion holes on the corresponding bearing plates 22. A pin is inserted between the pin hole 12 and the corresponding insertion hole, so that the base plate 21 can be detachably installed in the base frame 1 through the two bearing plates 22. In order to prevent the pin from disengaging during use, the pin hole 12 is provided with threads, and the pin is provided with a threaded section that engages with the threaded pin hole 12.

[0038] like Figure 2 and Figure 3As shown, an anchor bolt mechanism 23 is assembled at the bottom end of the base plate 21. The anchor bolt mechanism 23 includes a bidirectional lead screw 235 that is horizontally rotatably mounted between two bearing plates 22 via bearings. Two moving rods 233 are threadedly connected to each of the two threaded sections of the bidirectional lead screw 235. The two sets of moving rods 233 are symmetrically arranged about equidistant points between the two bearing plates 22. A stroke hole 211 is opened on the two flanged bending structures corresponding to each moving rod 233. The stroke hole 211 is a horizontally extended hole. The moving rod 233 moves along... Two corresponding stroke holes 211 slide, and the stroke holes 211 are also used to limit the sliding range of the moving rod 233. Each moving rod 233 is hinged with two connecting rods 234, and the other end of the two connecting rods 234 is hinged with a flip shaft 231. The flip shaft 231 is horizontally rotatably installed between the two flanged bending structures. Four anchor rods 232 are sleeved on and welded to the flip shaft 231. The four anchor rods 232 are located between the two connecting rods 234 and are equidistantly distributed. The anchor rods 232 are perpendicular to the flip shaft 231.

[0039] The anchor bolt mechanism 23 is an expandable structure. When not in use, the anchor bolt 232 is in a state close to parallel with the base plate 21, so that the anchor bolt 232 can be basically hidden and stored in the base frame 1 together with the base plate 21, making the structure compact, easy to transfer and transport, and avoiding the tip of the anchor bolt 232, reducing the risk of accidental injury during handling. When temporarily used, the two sets of moving rods 233 can be driven to slide away from each other by rotating the bidirectional screw 235. The moving rods 233 drive the flip shaft 231 to rotate through the connecting rod 234, so that the anchor bolt 232 rotates from the stored state to the vertical state with the flip shaft 231. After unfolding, the anchor bolt 232 is inserted into the ground until the insertion foot 11 is also finally inserted into the ground. The anchor bolt 232 anchors as the main anchor and the insertion foot 11 inserts into the ground as the auxiliary anchor. In order to increase the friction between the anchor bolt 232 and the soil layer to enhance the pull-out resistance, the anchor bolt 232 can be provided with rotating threads, concave and convex points and other structures.

[0040] like Figure 1 , Figure 2 and Figure 4As shown, the buffer base 3 includes a support frame 31 that is slidably embedded in the base frame 1. The support frame 31 has a rectangular frame structure. Spring grooves 311 are distributed around the rectangular window on the support frame 31. A damping spring 32 is vertically welded in each spring groove 311. The top of all the damping springs 32 is horizontally welded to the base frame 33. The base frame 33 has a rectangular frame structure. The side of the base frame 33 is smaller than the side of the support frame 31. The rectangular windows of the base frame 33 and the support frame 31 are the same size and arranged vertically opposite each other. A buffer barrier 35 is fixed to the inner wall of the base frame 1 near the top by screws. The buffer barrier 35 is made of elastic rubber material. The inner wall size of the buffer barrier 35 is slightly smaller than the side wall size of the base frame 33. In the use mode, this ensures that there is effective elastic contact between the buffer barrier 35 and the side walls of the base frame 33. An isolation pad 34 is fixedly installed between the support frame 31 and the base frame 33 by screws. The isolation pad 34 is made of elastic rubber and has a rectangular frame structure, surrounding the rectangular windows of both the support frame 31 and the base frame 33. It should be noted that the selected damping spring 32 has appropriate stiffness, providing reliable support for the base frame 33 based on the support frame 31. The arrangement of the isolation pad 34 further enhances the support stability between the base frame 33 and the support frame 31.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, one end of the fixed support plate 4 is hinged to the top of the base frame 33 via a fixed hinge seat; the upper surface of the fixed support plate 4 can be fitted with existing fixing components for fixing photovoltaic panels, and can also be fixed with bolts to a longitudinally and laterally telescopic fixing frame, which is suitable for fixing photovoltaic panels of different sizes and models; it should be noted that the fixing structure on the fixed support plate 4 for fixing photovoltaic panels is not shown in the attached drawings.

[0042] like Figure 1 , Figure 5 and Figure 6 As shown, the bottom end of the fixed support plate 4 is fixed with two slide rails 41 that are perpendicular to their hinge axes and are bolted together. The two slide rails 41 are arranged close to the two sides of the fixed support plate 4. The slide rails 41 have multiple pin holes that are evenly distributed along their extension direction and are horizontally through. The inclined support 5 includes a support frame 51 that is hinged to the top of the base frame 33 at one end through a fixed hinge seat. The other end of the support frame 51 is hinged to two sliding hinge blocks 52. The sliding hinge blocks 52 and the slide rails 41 are slidably engaged. The sliding hinge blocks 52 have three pin holes that are horizontally through. The pin holes of the sliding hinge blocks 52 and the slide rails 41 are the same size and the spacing is equal. The angle of the inclined support 5 on the fixed support plate 4 can be adjusted by sliding the sliding hinge blocks 52. After adjusting to a suitable angle, the locating pins are inserted into the aligned pin holes of the sliding hinge blocks 52 and the slide rails 41 to fix it.

[0043] The buffer base 3 can slide vertically within the base frame 1 as a whole, and can switch between storage mode and use mode at different height positions; when the bottom end of the support frame 31 contacts the base plate 21, it is in storage mode, and when the fixed support plate 4 is placed in a horizontal position, the buffer base 3, the fixed support plate 4, and the diagonal support 5 can be stored together within the base frame 1, as can be seen in detail. Figure 5 As shown; in the storage mode, when not in use, combined with the retractable design of the anchor mechanism 23, the entire structure can be basically stored in the base frame 1, which is neat and compact, greatly reducing the space occupied during transportation, and is also convenient for handling and stable placement during transportation. It can also avoid the exposed support structure from being bumped, thus achieving storage protection and reducing the risk of collision with people during handling.

[0044] A locking structure is provided between the buffer base 3 and the base frame 1 in the vertical direction. In this embodiment, the locking structure is a pin-and-hole locking mechanism. Three holes are provided on the side wall of the support frame 31 that are adjacent to the two bearing plates 22. Pin holes 12 that correspond to the pin holes are provided on both sides of the base frame 1 and on the corresponding side of the support frame 31. The three pin holes 12 that mate with the support frame 31 and the two pin holes 12 that mate with the bearing plates 22 on the same side wall of the base frame 1 are distributed vertically. The two sets of pin holes 12 have the same size and structure, that is, the matching pins are also the same, which has universal interchangeability so as to facilitate use without difference.

[0045] When placing the bracket, after the bottom anchoring is completed, the buffer base 3 can be slid upwards and locked into the base frame 1 via the locking structure to switch to the usage mode, such as... Figure 6As shown, when at this height, the upper end of the support frame 31 contacts the lower edge of the buffer enclosure 35, and the base frame 33 is in elastic contact with the buffer enclosure 35, and the buffer base 3 is in a buffer state. In the usage mode, the fixed support plate 4 rises to the outside of the base frame 1, and the angle of the inclined support 5 can be adjusted accordingly to fix the inclined support 5 of the fixed support plate 4. At this time, the base frame 1 is divided into a counterweight cavity for filling counterweight materials by the bottom plate 21 and the buffer base 3. In the construction area, materials can be obtained locally, and soil can be dug on-site to fill the counterweight cavity. In order to increase the counterweight, it is preferred to dig out materials such as sand and gravel for use as counterweight. When filling, the counterweight material can pass through the rectangular windows of both the support frame 31 and the base frame 33. At the same time, the isolation pad 34 can prevent the counterweight material such as sand and gravel from entering the gap between the base frame 33 and the support frame 31. By filling the counterweight cavity, an integrated counterweight is formed, which lowers the center of gravity and works in conjunction with the anchor base 2 to further enhance the stability of the support. After the counterweight cavity is filled, a support layer is formed between the support frame 31 and the base plate 21, changing the suspended state of the support frame 31 after locking and strengthening the overall integrity of the upper and lower supports. In addition, the counterweight cavity is located in a relatively sealed frame structure composed of the base plate 21 and the base frame 1. The edges of the base plate 21 can be sealed with sealing strips to improve the sealing of the contact with the base frame 1, so as to avoid leakage of the counterweight material, which is mainly composed of sand and gravel. In outdoor environments, it can effectively prevent or reduce the erosion and loss of the counterweight material by rainwater, maintaining the temporary effectiveness of the counterweight during use. At the same time, the rectangular window of the base frame 33 can be covered by an additional cover plate to further improve the overall sealing of the counterweight cavity. The stability of the temporary fixation of the support is improved by multiple methods such as anchoring and adding counterweight, so as to avoid slippage and tilting. After the counterweight is loaded, the photovoltaic panels can be fixed on the fixed support plate 4. During use, the damping spring 32 and the isolation pad 34 together form a flexible isolation layer, which can effectively attenuate and block the ground vibration during isolation construction from being transmitted further upward through the base frame 1. The damping spring 32 can actively dissipate vibration energy. In addition, combined with the elastic support of the buffer enclosure 35 on the side wall of the base frame 33, it can enhance the wind resistance to strong winds, absorb and weaken the impact of strong winds on the support, reduce fatigue damage to the support structure as a whole, and protect the photovoltaic panels, extending their service life.

[0046] When the construction site needs to be changed, the support can be quickly disassembled and retracted. Specifically, first, loosen the diagonal support 5, adjust the fixed support plate 4 to a horizontal state, then pull out the pin between the base frame 1 and the bearing plate 22, so that the anchor base 2 is separated from the base frame 1. Lift the base frame 1 to quickly remove the filling counterweight material. Then, by repeatedly rotating the bidirectional screw 235 forward and backward, the anchor rod 232 is loosened from the ground, and the anchor base 2 is pulled upward from the ground as a whole. After the anchor rod 232 is retracted, the anchor base 2 is fixed back to the base frame 1. Finally, loosen the pin between the support frame 31 and the base frame 1, and retract the buffer base 3 into the base frame 1. After retraction and deformation, it can be transported and transferred.

[0047] It should be noted that the locating pin and the pivot pin are not shown in the figure.
