Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and specifically relates to a photovoltaic support device. Background Technology

[0002] With the rapid development of technology, the photovoltaic industry is currently experiencing rapid growth. Electronic components and photovoltaic generators are constantly being updated and are becoming more streamlined, driving up the demand for photovoltaic mounting systems. Upstream in the industry, the cost of photovoltaic mounting systems mainly consists of bulk material costs. These are customized steel products, and in terms of production, fixed mounting systems are composed of components such as columns, main beams, purlins, and foundations. The production process involves mechanical design, machining, and galvanizing. Therefore, photovoltaic mounting systems are affected by the cyclical nature of commodity prices. Using natural materials to make photovoltaic mounting systems can effectively solve these problems. The scientific and rational use of natural materials for photovoltaic mounting components can effectively reduce costs and facilitate transportation and installation.

[0003] Traditional photovoltaic (PV) mounting systems are currently expensive, with high labor costs for maintenance. In coastal areas or regions prone to acid rain, the structural strength of these systems is compromised. Furthermore, the PV mounting system industry lacks a comprehensive quality control and assurance system, and manufacturers lack unified production standards, resulting in inconsistent product quality and compromised reliability, ultimately hindering market competitiveness. In addition, PV mounting system manufacturers currently exhibit high homogeneity, lacking their own core technologies and largely relying on imitation, leading to insufficient product innovation. Moreover, some traditional mounting materials (such as galvanized steel) cause significant environmental pollution during production and are non-renewable, failing to meet sustainable development requirements. The recycling and reuse rates of these materials are low, and discarded mounting systems may cause secondary pollution. Some metal mounting systems are heavy, requiring more manpower and machinery for installation, increasing installation difficulty and costs. Material corrosion and aging necessitate regular maintenance and replacement, further increasing operation and maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a photovoltaic support structure made of natural materials. This overcomes the deficiencies of traditional metal supports, and the use of mortise and tenon joints reduces metal costs. The technical solution is as follows:

[0005] A photovoltaic support device includes columns, a foundation sleeve, and an inclined beam; the two ends of the inclined beam are respectively connected to two columns, and a crossbeam is installed on the top of the inclined beam; the columns are connected to concrete pipe piles by bolts, and the concrete pipe piles are sunk into the ground as a foundation.

[0006] Preferably, the inclined beam and the column are connected by triangular connectors and fastened with hexagonal bolts.

[0007] Preferably, a front support and a rear support are provided between the inclined beam and the column. One end of the front support and the rear support are fixed to the inclined beam with a triangular connector, and the other end is connected to the column with a clamp made of bamboo and wood composite material.

[0008] Preferably, the inclined beam is provided with a mortise for a sliding pin, and the crossbeam is provided with a tenon for the sliding pin, the tenon being located inside the mortise of the sliding pin; the tenon on the crossbeam is thicker at the bottom and thinner at the top.

[0009] Preferably, the column comprises multiple columns, each of which is provided with a tenon, a tenon slot, and a tenon slot. The tenons of the wedge tenons are inserted into each other's tenon slots, and then secured by inserting tenons into the tenon slots of the wedge tenons.

[0010] Preferably, the foundation includes prestressed tie rods, cables, and enlarged head anchor bolts; the tie rods, made of virgin bamboo and wood, are connected to the enlarged head anchor bolt foundation and the column by bolts, and the cables are connected between two adjacent concrete pipe piles by bolts.

[0011] Preferably, the cable comprises multiple layers connected by cable clamps.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Using virgin materials overcomes the limitations of metal resources and reduces environmental impact. In regions rich in natural materials, sourcing is easier, reducing the need for complex processing steps. This also reduces the weight of the support structure, lowering installation difficulty and cost. Bamboo's high strength, lightweight, and rapid growth characteristics not only make it environmentally friendly but also allow it to blend seamlessly with the local environment.

[0014] Using mortise and tenon joints instead of traditional bolts, relying on the bamboo and wood themselves for connection reduces the need for metal bolts, screws, and other hardware, thus minimizing metal mining and environmental impact. The mortise and tenon structure is highly durable and less prone to loosening and damage, reducing maintenance and replacement frequency. Furthermore, the tight fit of the mortise and tenon joints effectively distributes and transfers loads, reducing stress concentration and exhibiting good toughness and deformation capacity under dynamic loads such as earthquakes, contributing to improved seismic performance. The ease of installation and disassembly, eliminating the need for exposed bolts and screws, enhances the overall visual appeal of the support structure. Attached Figure Description

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Please refer to Figure 1-5 As shown, a photovoltaic support device includes a column 1, a foundation sleeve 9, and an inclined beam 4; the two ends of the inclined beam 4 are respectively connected to two columns 1, and a crossbeam 5 is installed on the top of the inclined beam 4; the column 1 is connected to a concrete pipe pile 16 by bolts, and the concrete pipe pile 16 is sunk into the ground as a foundation.

[0023] The diagonal beam 4 and the column 1 are connected by triangular connectors 7 and secured with hexagonal bolts. A front support 2 and a rear support 3 are provided between the diagonal beam 4 and the column 1. One end of the front support 2 and the rear support 3 is fixed to the diagonal beam 4 by the triangular connectors 7, and the other end is connected to the column 1 by a clamp 8 made of bamboo and wood composite material. The diagonal beam 4 is provided with mortises 11 for the sliding pin, and the crossbeam 5 is provided with tenons 10 for the sliding pin, the tenons being located within the mortises 11 of the sliding pin; the tenons 10 on the crossbeam 5 are thicker at the bottom and thinner at the top.

[0024] The column 1 includes multiple columns, each of which is provided with a tenon 12 of a wedge tenon, a tenon slot 14 of a wedge tenon, and a tenon slot 15 of a wedge tenon. The tenons 12 of the wedge tenons are inserted into each other's tenon slots 15 of the wedge tenons, and then secured by inserting the tenons 13 of the wedge tenons into the tenon slots 14 of the wedge tenons.

[0025] The photovoltaic support system includes prestressed tie rods, cables, and enlarged head anchor foundations. Tie rods 17, made of virgin bamboo and wood, are connected to the enlarged head anchor foundation 20 and the column 1 by bolts. Cables 18 are bolted between two adjacent concrete pipe piles 16. The cables 18 consist of multiple layers connected by cable clamps.

[0026] Please refer to Figure 1 As shown, a fixed photovoltaic support based on natural materials is described. The process includes first laying a foundation on the ground, then fixing a composite bamboo-wood sleeve 9 to the ground as a pile using concrete pouring. On the ground, the inclined beam 4 and the column 1 are connected using triangular connectors 7 and secured with M12 hex bolts. The assembly is then lifted, and the front and rear columns 1 are placed on the top sleeve 9. A slope measuring instrument is placed on the inclined beam 4, and the height of the front and rear columns 1 is adjusted according to the reading. Bamboo and wood nails are passed through pre-drilled holes to fix the columns 1 and sleeve 9. One end of the front support 2 and the rear support 3 are fixed to the inclined beam 4 using triangular connectors 7, and the other end is connected to the column 1 using a clamp 8 made of bamboo-wood composite material. The crossbeam 5, made of natural bamboo and wood, is lifted above the inclined beam 4, inserted into the pre-drilled mounting holes on the inclined beam 4, and pushed down into place.

[0027] Please refer to Figure 5 As shown, a flexible photovoltaic support system based on natural materials is described. The system involves first sinking prestressed high-strength concrete 16 into the ground as a foundation using static pressure or hammering. A column 1 is then connected to the concrete pipe piles 16 via bolts. Next, tie rods 17 made of native bamboo and wood are connected to the expanded head anchoring foundation 20 and the column 1 via bolts. After a row of concrete pipe piles 16 is installed, cables 18 made of hemp rope are raised into the air and bolted between the pipe piles 16. Several cables are then connected together using cable clamps to form a multi-unit flexible photovoltaic support system.

[0028] Specifically, the high-strength wood-bamboo composite material is made by modifying silica sol with a silane coupling agent, adding bamboo and wood powder modified with a coupling agent (titanium ester coupling agent), ultrasonically treating it, and then hot-pressing it in a molding machine, as shown in the tenon with the mortise on the diagonal beam 4 and the tenon with the mortise on the crossbeam 5. Ammoniacal alkylamine copper is then immersed into the bamboo and wood material under high pressure, and finally, a waterproof surface coating is applied. The original material only undergoes anti-corrosion and waterproofing treatments.

[0029] For details, please refer to Figure 2-3Below the fixed photovoltaic support beam 5, there is a tenon 10 for a sliding pin. The tenon 10 is thicker at the bottom and tapers to a thinner shape at the top via a zigzag segment. On the inclined beam 4, there is a mortise 11 for a sliding pin. The mortise 11 is a square cutout with one side slightly larger and the other side slightly smaller. During installation, the tenon 10 of the beam 5 is aligned with the larger cutout of the mortise 11 of the inclined beam 4, and after installation, it is pushed down to the bottom. Under the action of the support's own weight and the pressure of the photovoltaic panel, they are firmly joined together.

[0030] For details, please refer to Figure 4 The fixed photovoltaic support column 1 can be made into two relatively short columns by using a wedge tenon, which can be tightly joined together to enhance the bending resistance. The column 1 is made by inserting the two tenons 12 of the wedge tenon into each other's mortises 14, and then inserting the wedge 13 into the reserved wedge hole 14 to make it tight and secure.

[0031] Finally, it should be noted that the two types of tenon and mortise structures described in this utility model—the sliding pin and the wedge tenon—are only for the purpose of briefly describing this utility model. They do not imply that only these two structures exist, nor that only tenon and mortise structures can be used. Any tenon and mortise structure can be replaced by a bolt structure, and this should not be construed as a limitation of this utility model. Furthermore, after all tenon and mortise structures are installed and conform to practical requirements, the installation parts can be further glued to prevent human-caused disassembly and damage.
