Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to an anchor type photovoltaic support foundation. Background Art

[0002] Solar energy is a rich and clean renewable energy source, and its photovoltaic power generation technology is highly representative and has become an important development method. In recent years, with the expansion of the scale of photovoltaic power stations, in order to make full use of solar energy resources and solve the problem of reduced flat land resources, the "mountain photovoltaic" model has been proposed. However, the mountainous terrain is complex and the slopes in some areas are large. In order to solve the problem of component installation, some distributed photovoltaic projects have adopted anchor-type photovoltaic bracket foundation structures.

[0003] The traditional anchor-type photovoltaic support foundation design usually adopts a simple combination of anchors and photovoltaic modules. Specifically, the anchor is placed in a pre-prepared hole, and the bonding force of materials such as rocks, mortar or fine stone concrete (structural adhesive) in the hole is used to tightly combine with the anchor to effectively resist the horizontal force, uplift force and column bottom bending moment transmitted from the upper structure. However, mountain photovoltaics are generally agricultural photovoltaics or forest photovoltaics, and use a column fixed support form, so the moment caused by gravity on the photovoltaic module is relatively large, such as the Chinese utility model patent (authorization announcement number: CN214832638U name: An anchor-type photovoltaic support foundation). The above-mentioned traditional anchor-type photovoltaic support foundation is prone to insufficient resistance to bending moments, and at the same time, it cannot withstand the uplift force generated by wind loads, causing problems such as slope sliding and photovoltaic module instability, thereby endangering the safety of the reservoir area, damaging the photovoltaic power generation system and causing economic losses. Utility Model Content

The receiving groove is distributed in a spiral shape, and one end of the receiving groove close to the photovoltaic base extends to the threaded structure, and the steel cable outside the anchor rod body is wound in the receiving groove.

[0010] Preferably, a C-circular plate is fixed on the steel cable, a positioning ball is fixed on the inner wall of the anchor rod body, and the length of the barb extending out of the anchor rod body is controlled by the C-circular plate pressing against the positioning ball.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Under the terrain conditions of mountain slopes, photovoltaic modules will generate torque on the slope due to gravity, and will generate upward pull due to wind loads.

[0026] like Figure 1 , 2 4, an anchor-type photovoltaic support foundation comprises a hollow anchor body 1, a reinforcement plate 2 and a photovoltaic base 3, the anchor body 1 is provided with an anti-slip mechanism, the reinforcement plate 2 is detachably mounted on the end of the anchor body 1 away from the anti-slip mechanism through the photovoltaic base 3, a steel cable 4 penetrating the photovoltaic base is placed in the anchor body 1, a circular plate A 5 is fixed on the steel cable 4, a side support plate 6 is hinged on the circular plate A 5, a rocker 7 is rotatably mounted on the middle of the side support plate 6, a slide groove is opened on the anchor body 1 along its axial centerline direction, and the hinged end of the side support plate 6 and the rocker 7 are far away from the anti-slip mechanism. One end of the side support plate 6 is slidably installed in the slide groove. Under the terrain conditions of mountain slopes, the photovoltaic components will generate a torque on the slope due to the action of gravity, and will generate upward pulling force due to the action of wind load, etc. The bottom of the main anchor rod is designed with an anti-slip mechanism, and through the asymmetric design of the side support plate 6 in the middle of the anchor rod body 1, the unfolded side support plate 6 can interact with the soil, poured mortar, etc. to generate a pre-tightening force, thereby offsetting the torque generated by the photovoltaic component due to its own gravity, thereby increasing the stability of the photovoltaic component.

[0027] In this embodiment, if Figure 2 and 4 As shown, a ball groove 8 is opened on the inner wall of the anchor rod body 1, and the slide groove is connected to the ball groove 8. A limiting ball 9 is fixed on the end of the rocker 7 away from the side support plate 6, and the ball groove 8 is used to lock the limiting ball 9. A limiting frame 10 is fixed on the outer wall of the anchor rod body 1, and the limiting frame 10 is used to support the side support plate 6. When the A circular plate 5 moves driven by the steel cable 4, the limiting ball 9 is against the end of the slide groove and cannot move, so the side support plate 6 can be initially opened. After the initial expansion is achieved, mortar or structural adhesive and other materials are poured between the anchor rod body 1 and the hole. At this time, the rocker 7, under the action of pressure, makes the limiting ball 9 slide close to the side support plate 6, and finally stops moving at the ball groove 8, so that the side support plate 6 is further expanded. The further expanded side support plate 6 resists the impact force of mortar, etc. under the support of the limiting frame 10.

[0028] In this embodiment, if Figure 2 and 3As shown, the anti-slip mechanism includes a barb 11 and a B circular plate 12, the barb 11 is hinged on the B circular plate 12, the B circular plate 12 is fixed on the steel cable 4, a slot 13 is provided on the anchor body 1, the barb 11 is inserted into the slot 13, during the installation process, the steel cable 4 realizes the common expansion of the barb 11 and the side support plate 6, the slot 13 and the limit ball 9 groove 8 realize the position fixation of the barb 11 and the side support, which is easy to operate, is conducive to construction and installation in mountainous areas, and has higher applicability. At the same time, when the barb 11 is retracted into the anchor body 1, since the barb 11 is placed on the B circular plate 12, the barb 11 and the steel cable 4 maintain an angle, and the angle prevents the barb 11 from getting stuck when extending out of the anchor body 1.

[0029] In this embodiment, if Figure 5 and 6 As shown, the anchor body 1 is connected to the photovoltaic base 3 through a threaded structure, and a receiving groove 14 is opened on the outer wall of the reinforcement plate 2. The receiving groove 14 is spirally distributed, and the receiving groove 14 extends to the threaded structure at one end close to the photovoltaic base 3. The steel cable 4 located outside the anchor body 1 is wound in the receiving groove 14. There is a screw hole 18 at the center of the bottom of the photovoltaic base 3, and the length of the thread 17 is greater than the thickness of the reinforcement plate 2. This installation method makes maintenance more convenient, and in the case of component instability, the component can be recycled, thereby increasing economic benefits and reducing the degree of harm.

[0030] In this embodiment, if Figure 1-3 As shown, a C-circular plate 15 is also fixed on the steel cable 4, and a positioning ball 16 is fixed on the inner wall of the anchor body 1. The length of the barb 11 extending out of the anchor body 1 is controlled by the C-circular plate 15 pressing against the positioning ball 16 to avoid excessive stretching of the steel cable 4, which causes the barb 11 to be stuck in the slot 13 and bend, affecting the use of the barb 11.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
