Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a photovoltaic support system that can be quickly folded and unfolded. Background Technology

[0002] With the surge in demand for distributed photovoltaic and mobile power generation, the shortcomings of traditional fixed photovoltaic brackets have become increasingly prominent, making it difficult to adapt to the needs of new scenarios.

[0003] Traditional scaffolding systems employ rigid truss structures with fixed, non-compressible volumes, resulting in low space utilization during logistics and significantly increased unit transportation costs, particularly impacting long-distance or large-scale projects. Furthermore, scaffolding installation requires more on-site personnel, involving cumbersome and time-consuming processes, driving up labor costs and extending project construction cycles, leading to poor overall economic efficiency. In addition, the connection between the scaffolding and the concrete pier has drawbacks. The traditional connection method uses pre-embedded bolts, which are convex and easily damaged male heads. This requires precise positioning during construction to avoid affecting subsequent installation; furthermore, the exposed bolt parts are susceptible to damage from impacts and cement slurry contamination, requiring additional protection efforts and further increasing construction difficulty.

[0004] In summary, the problems with traditional fixed photovoltaic (PV) brackets in transportation, installation, and connection can no longer meet the current PV project requirements for high efficiency, low cost, and ease of construction. There is an urgent need for new bracket systems to solve these pain points. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic support system that can be quickly folded and unfolded, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following solution: A photovoltaic support system that can be quickly folded and unfolded includes two sets of corresponding bases, which are connected by a foldable component. Both sets of bases are equipped with support components; The support assembly includes a first support rod, a second support rod, a third support rod, and an inclined beam; The top of the base is provided with a storage groove along its layout direction. The first support rod and the second support rod are arranged obliquely and intersectingly within the storage slot; The inclined bottom end of the first support rod abuts against the end of the storage groove, the inclined bottom end of the second support rod is hinged to the end of the storage groove, and the rod body of the first support rod is hinged to the rod body of the second support rod. The inclined top ends of the first support rod and the inclined top ends of the second support rod are both hinged to the beam body of the inclined beam; The third support rod is vertically inserted into the inside of the storage groove, and the top end of the third support rod is hinged to the beam body of the inclined beam. The two sets of bases are connected to the concrete piers through pre-embedded components.

[0007] Furthermore, the vertical projections of the inclined beam, the first support rod, and the second support rod are arranged sequentially and are all located inside the storage groove.

[0008] Furthermore, the interior of the storage slot is sequentially divided into a first slot, a second slot, and a third slot; The third support rod and the inclined beam can be retracted into the first groove. The first support rod can be retracted into the second groove; The second support rod can be retracted into the third groove.

[0009] Furthermore, the bottom of the inclined beam is provided with an inclined groove; An adjustment plate is hinged to the top of the third support rod; The adjustment plate is inserted inside the inclined groove.

[0010] Furthermore, the foldable component includes two sets of cross-hinged connecting rods, one end of which is fixedly connected to the side wall of one base, and the other end is slidably connected to the side wall of the other base. Of the two sets of connecting rods connected on the same base, one connecting rod is fixedly connected to the base, and the other connecting rod is slidably connected to the base.

[0011] Furthermore, the embedded components include an anchoring base, a universal ball seat, and an internally threaded sleeve; The universal ball seat is fixed to the upper end of the anchor base; The internally threaded sleeve is connected to the universal ball in the universal ball seat.

[0012] Furthermore, the anchoring base has an inverted "T" shaped structure, and barbs are provided on the side wall of the anchoring base.

[0013] Furthermore, a protective cap is fastened to the top of the internally threaded sleeve.

[0014] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows: The photovoltaic bracket provided by this utility model can be quickly folded and stored, significantly reducing its volume and greatly improving the utilization rate of logistics and transportation space, reducing the unit cost of single transportation, and saving storage space. It is especially suitable for projects with high logistics costs or limited space. The photovoltaic bracket is easy to deploy and requires no complex splicing and calibration, which can significantly reduce the number of on-site installation personnel and the difficulty of operation, and greatly shorten the installation and dismantling time. It can also be adapted to multiple scenarios such as distributed photovoltaics, industrial and commercial rooftop photovoltaics, temporary power supply, and mobile power generation, with better disaster resistance and safety, solving the problems of poor adaptability and low construction efficiency of traditional brackets. This utility model adopts a pre-embedded universal leveling internal threaded sleeve structure, which eliminates the need for on-site management precision and greatly reduces the difficulty of construction. The protective cover can prevent cement slurry blockage, and the universal structure can eliminate the additional stress caused by installation misalignment, protect the bolts and concrete structure, and extend the fatigue life of the connection parts.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] Example 1 See Figure 1-4 As shown, this embodiment provides a photovoltaic support system that can be quickly folded and unfolded, including two sets of corresponding bases 1, which are connected by a foldable component 2. Support components 3 are mounted on both sets of bases 1; The two sets of bases 1 are connected to the concrete piers through pre-embedded components 5.

[0020] Specifically, as shown in 1-2, the support assembly 3 includes a first support rod 301, a second support rod 302, a third support rod 303, and an inclined beam 304; A storage groove 4 is provided at the top of the base 1 along its layout direction; The first support rod 301 and the second support rod 302 are obliquely and cross each other in the storage slot 4; The inclined bottom end of the first support rod 301 abuts against the end of the storage groove 4, the inclined bottom end of the second support rod 302 is hinged to the end of the storage groove 4, and the rod body of the first support rod 301 is hinged to the rod body of the second support rod 302. The inclined top ends of the first support rod 301 and the inclined top ends of the second support rod 302 are both hinged to the beam body of the inclined beam 304. The third support rod 303 is vertically inserted into the storage slot 4, and the top of the third support rod 303 is hinged to the beam body of the inclined beam 304. The two sets of bases 1 are connected to the concrete piers through pre-embedded components 5.

[0021] Specifically, the second support rod 302 can rotate around its hinge axis with the storage groove 4, thereby storing the second support rod 302 inside the storage groove 4. Since the first support rod 301 is hinged to the second support rod 302, the first support rod 301 can also be rotated and stored inside the storage groove 4. The inclined beam 304 can be stored in the storage groove 4 along with the storage process of the first support rod 301 and the second support rod 302, and maintain the same horizontal plane as the first support rod 301 and the second support rod 302. The third support rod 303 is pulled out from the storage groove 4 and folded to be parallel to the bottom end of the inclined beam 304, and can be stored in the storage groove 4 along with the inclined beam 304. After storage, the foldable part 2 is folded to bring the two sets of bases 1 closer together and reduce space.

[0022] It should be noted that the vertical projections of the inclined beam 304, the first support rod 301, and the second support rod 302 are arranged sequentially and are all located inside the storage groove 4.

[0023] It should be noted that, as Figure 2As shown, the interior of the storage slot 4 is divided into a first slot 401, a second slot 402, and a third slot 403 in sequence; The third support rod 303 and the inclined beam 304 can be retracted into the first groove 401; The first support rod 301 can be retracted into the second groove 402; The second support rod 302 can be retracted into the third groove 403.

[0024] It should be noted that the first groove 401, the second groove 402 and the third groove 403 are interconnected. The second groove 402 and the third groove 403 have the same depth. The depth of the first groove 401 is greater than the depth of the second groove 402 or the third groove 403, so as to accommodate the third support rod 303 and the inclined beam 304 at the same time.

[0025] Specifically, see Figure 1 As shown, in order to facilitate the support of the inclined beam 304, an inclined groove 305 is provided at the bottom of the inclined beam 304. An adjustment plate 306 is hinged to the top of the third support rod 303; The adjustment plate 306 is inserted inside the inclined groove 305.

[0026] Specifically, by adjusting the cooperation between the plate 306 and the inclined groove 305, it is easier for the third support rod 303 to support the inclined beam 304, and it is also easier to store the third support rod 303.

[0027] Example 2 See Figure 1 As shown, this embodiment provides the specific structure of the foldable component 2 in Embodiment 1. Specifically, the foldable component 2 includes two sets of cross-hinged connecting rods. One end of the connecting rod is fixedly connected to the side wall of one base 1, and the other end is slidably connected to the side wall of another base 1. Of the two sets of connecting rods connected to the same base 1, one connecting rod is fixedly connected to the base 1, and the other connecting rod is slidably connected to the base 1.

[0028] Specifically, the cooperation between the connecting rod and the base 1 can change the included angle between the two connecting rods, thereby achieving folding or extension to change the distance between the two bases 1.

[0029] Example 3 See Figure 3 As shown, this embodiment provides the specific structure of the embedded component 5 in Embodiment 1. Specifically, the embedded component 5 includes an anchoring base 501, a universal ball seat 502, and an internal threaded sleeve 503. The universal ball joint 502 is fixed to the upper end of the anchor base 501; The internal threaded sleeve 503 is connected to the universal ball in the universal ball seat 502.

[0030] It should be noted that the anchoring base 501 has an inverted "T" shaped structure, and barbs 504 are provided on the side wall of the anchoring base 501.

[0031] It should be noted that the top of the internal threaded sleeve 503 is fitted with a protective cap 505. For details, please refer to [link / reference needed]. Figure 4 As shown, the top end of the internal threaded sleeve 503 is provided with a spring buckle 506, and the bottom end of the protective cover 505 is provided with a buckle opening. The spring buckle 506 can be snapped into the buckle opening to achieve connection, and the internal threaded sleeve 503 is also provided with a sealing ring 507.

[0032] Specifically, in practical use, a simple line is laid out on the concrete pier formwork on site, and the entire embedded component 5 is placed directly on the design point on the formwork. Concrete is then poured directly. After curing, the protective cover 505 is easily removed with a pry bar, exposing the clean, universally adjustable internal threaded sleeve 503. A long screw is screwed downwards into the internal threaded sleeve 503 through the base 1. Even if the embedded part is slightly tilted, the downward force of the screw will automatically guide the internal threaded sleeve 503 to drive the universal ball to level itself within the universal ball seat 502, achieving self-adaptive alignment. When the torque reaches the set value, the tension of the screw presses the universal ball head tightly against the universal ball seat 502, and the friction changes it from a "universal" state to a "rigidly fixed" state, forming a firm connection. Furthermore, because the outer surface of the anchor base 501 is covered with barbs 504, it ensures a strong grip with the concrete. The universal ball seat 502 provides a foundation that allows for ±5° angular deflection, which is the core for eliminating verticality errors. The protective cover 505 can completely seal the internal threaded sleeve 503 during pouring to prevent cement slurry from entering. It can be removed by prying it open with a tool during installation to expose the threads.

[0033] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
