Description

Technical Field

[0001] The utility model is applied to the technical fields of photovoltaic ground piles, greenhouse ground piles and road guardrail ground piles, and particularly relates to a ground pile mechanism. Background Art

[0002] With the international community's emphasis on energy conservation and emission reduction, the rise of emerging industries, the application of solar energy products has become more and more extensive, and the application of photovoltaic power generation has become more common. Existing solar photovoltaic brackets are usually fixed by ground piles or cement piers. Ground piles are more widely used than cement piers because of their convenience. Existing ground piles are all pipe piles with spiral wings. Spiral solar photovoltaic bracket ground piles are generally suitable for deserts, grasslands, tidal flats, Gobi, frozen soil, etc., but their stability is not high, and the top of the ground pile is easily misaligned during installation. For some large solar energy devices, their load performance, stability, anti-subsidence and anti-pullout performance are poor, and there is a lack of effective protection structure, which makes the ground piles easily eroded by rainwater and rusted, affecting their service life.

[0003] There are two types of ground piles in the prior art: the first type is to dig a pit in the ground, fill it with concrete, and pre-set bolts on the concrete pile. After the concrete solidifies, the ground pile is installed on the concrete, and the position and height of the ground pile must be adjusted at the same time; the second type is a spiral ground pile. Although the pile body is screwed into the soil, the peripheral fins do not extend far beyond the main body, and the pull-out force and anti-tilt force are not obvious. In the process of screwing the ground pile into the soil, the soil around the ground pile is easily loosened, thereby reducing the pull-out force and anti-tilt force. However, the production of concrete pile mounting bases is labor-intensive and time-consuming, and is particularly susceptible to the influence of terrain, environment and temperature. For installation environments with harsh terrain, the transportation of materials is relatively troublesome, such as mountainous areas or deserts, where it is not convenient to transport concrete. If spiral piles are used for installation, the requirements for the installation position are high. Once the adjustment fails to meet the design requirements, it needs to be repositioned, which affects the construction schedule and greatly increases the material cost and labor cost. At the same time, it is easy to loosen the soil around the pile body, the wing does not extend far from the body, the soil gripping area is not large, the tilting force and the pulling force are not obvious, and there are requirements for the soil quality, and soft soil cannot be used. For example, the Chinese patent with the publication number CN213296335U discloses a photovoltaic spiral pile, which improves the firmness and stability of the photovoltaic panel by adjusting the number and angle of the upward support arms, and enhances the stability and firmness of the pile by adjusting the number and angle of the downward support arms. However, its installation method is spiral, and during the spiral process, it is easy to loosen the soil around the pile, thereby reducing the pull-out force and the tilting force. In addition, the support arm is prone to rust or loosening after years of wind and rain corrosion, making it difficult to withstand strong winds and rainstorms, and its stability is greatly reduced. Therefore, it is necessary to provide a ground pile mechanism that can increase the grip area, ensure the balance and stability of the ground pile, increase the reverse stop force, and prevent the ground pile from tilting. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a ground pile mechanism which can increase the gripping area, ensure the balance and stability of the ground pile, increase the reverse stop force, and prevent the ground pile from tilting easily.

[0005] The technical solution adopted by the utility model is: the utility model includes a pile body, a cavity is opened inside the pile body, the cavity is provided with anchor wings, positioning pieces and forming pieces, the positioning piece is arranged at the upper end of the forming piece, the anchor wings are positioned and matched with the positioning piece, the bottom end of the anchor wing passes through the positioning piece and is guided and matched with the forming piece, the pile body is opened with a plurality of guide holes, the guide holes are close to the waist of the forming piece, the forming piece is a structure that is narrow at the top and wide at the bottom, when external force applies downward pressure on the top of the anchor wing, the anchor wing passes through the guide hole along the waist of the forming piece and extends to the soil around the pile body.

[0006] It can be seen from the above scheme that the anchor wing extends toward the surrounding soil of the pile body according to the law of external force, and the anchor wing cooperates with the top pressure of the soil to form a claw-shaped structure, thereby increasing the grip area, enhancing the anti-tilting force of the pile body and increasing the pulling force of the pile body, ensuring its stability and firmness. The pile is not easy to tilt and has good compatibility. It is suitable for terrain with harsh environments. At the same time, the soil around the pile is not loosened, which is beneficial to improving the anti-pulling force and tilting force of the pile.

[0008] A preferred solution is that a through hole compatible with the anchor wing is opened on the top of the positioning member, and a first back-stopping mechanism is provided at the lower half of the anchor wing. The first back-stopping mechanism is close to the bottom end of the anchor wing, and the first back-stopping mechanism is a slope structure with a higher top and a lower bottom. When the anchor wing passes through the through hole, the first back-stopping mechanism is positioned and matched with the edge of the through hole.

[0012] A preferred solution is that in the molding structure of the molding, initially, the bottom end of the anchor wing is closely attached to the upper end of the waist surface of the molding.

[0013] A preferred solution is that an opening is provided at the top of the pile body, and a cap is provided at the edge of the opening.

[0024] The pile body 1 is planted with a pile driver. During the planting stage, the anchor wing 2 is hidden in the cavity, and the positioning member 3 positions the anchor wing 2 to prevent the anchor wing 2 from shifting. When the pile body 1 reaches the specified depth, the downward pressure on the pile body 1 is stopped, and the anchor wing 2 is pressed downward. The anchor wing 2 moves downward under the force. Since the forming member 4 is a slope structure that is narrow at the top and wide at the bottom, the anchor wing 2 is guided by the forming member 4 and passes through the forming hole 5 along the waist of the forming member 4, and regularly extends to the soil around the pile body 1 and is inserted into the soil. The anchor wing 2 cooperates with the top pressure of the soil to form a claw-shaped structure, thereby increasing the grip area, enhancing the anti-tilting force of the pile body 1 and increasing the pulling force of the pile body 1. The extension of the anchor wing 2 can not only ensure the balance of the pile, but also increase the reverse stopping force, to ensure that the pile is not easy to tilt when the object above is subjected to external force, thereby ensuring its practicality and stability.

[0025] like Figures 1 to 3 As shown, in this embodiment, a cone head 6 is provided at the bottom of the pile body 1, and the cone head 6 is in a cone shape, and the cone head 6 is a structure that is wide at the top and narrow at the bottom. The pile driver implements the pile planting on the pile body 1. During the pile planting stage, the cone head 6 guides the pile body 1. Under the guidance of the cone head 6, the pile body 1 is easier to insert into the soil without destroying the original solid state of the soil around the pile.

When the anchor wing 2 passes through the through hole 7, the first backstop mechanism 8 is positioned and matched with the edge of the through hole 7. The first backstop mechanism 8 is a protruding structure, and the first backstop mechanism 8 is used to prevent the anchor wing 2 from tilting itself in a natural state, so as to achieve a positioning effect.

[0028] When external force presses down the anchor wing 2, the anchor wing 2 moves downward under the force, and the second stop mechanism 9 passes through the through hole 7. The second stop mechanism 9 is stuck at the edge of the through hole 7 to prevent the anchor wing 2 from retreating after being extended.

[0029] like Figure 2and Figure 5 As shown, in this embodiment, the anchor wing 2 includes a plurality of support bars, and the support bars are metal structures. The metal structure can ensure that the anchor wing 2 is not deformed and bent by the compression of the soil, and can also ensure the stability of the anchor wing 2.

The guide holes 5 are located below the waist of the molded part 4, and the anchor wings 2 extend from the several groups of symmetrically arranged guide holes 5, regularly extend toward the soil around the pile body 1, and insert into the soil. The anchor wings 2 cooperate with the top pressure of the soil to form a claw-shaped structure, increase the grip area, and ensure its three-dimensional stability.

[0031] like Figure 2 and Figure 7 As shown, in this embodiment, the waist surface of the molding 4 is a curved surface structure, and initially, the bottom end of the anchor wing 2 is closely attached to the upper end of the waist surface of the molding 4. The waist surface of the molding 4 guides the extension of the anchor wing 2.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the top of the pile body 1 is provided with an opening, and a cap 10 is provided at the edge of the opening.
