[Patent Description] A kind of solar photovoltaic power generation device

[Technical Field]

The invention relates to a support fixing device, in particular to a ground anchor pile of a solar photovoltaic power generation device.

【Background technique】

As the energy supply is becoming increasingly tense and the environment is deteriorating, solar photovoltaic power generation is expanding as a new energy source. As a supporting structure of photovoltaic power generation system, photovoltaic support system is an important part of photovoltaic power generation system. Solar photovoltaic supports are mostly arranged in large areas. Therefore, in addition to sufficient strength and rigidity, solar photovoltaic supports must have good mountability. As a key component connecting the solar photovoltaic support system to the ground, the spiral pile plays an important role in ensuring the stability and safety of the overall system. However, the spiral piles currently used have shortcomings. First, they are not hard enough. When they hit the ground, they can't drill when they encounter hard objects such as stones, which leads to labor and labor, and another method (digging and pouring cement). It is time-consuming, laborious and not environmentally friendly, which greatly affects the progress of the project and increases the cost. Secondly, the spiral pile has the largest friction between the tip and the ground when drilling into the ground, and the original zinc layer protection also destroys the most, resulting in the whole spiral pile. The pointed part began to rust and corrode.

[Content of the Invention]

The present invention is to solve the above-mentioned deficiencies, and provides a ground anchor pile of a solar photovoltaic power generation device.

The above object of the present invention is achieved by the following technical solution: a ground anchor pile of a solar photovoltaic power generation device, comprising: a cone tube and a drill bit, the cone tube and the drill bit are welded, and the cone tube is provided Spiral piece.

The drill bit has a cone shape and may be a polygonal cone such as a triangular pyramid, a quadrangular pyramid, a pentagon cone or a hexagonal cone, or may be a cone.

The drill bit is provided with a spiral piece, so that the ground anchor pile and the soil are mutually squeezed, which is more powerful and firmer.

The taper tube is made of steel pipe and has a hardness of only 70 degrees Brine. However, the drill bit is made of cast steel and has a hardness of 160 degrees Brine, and the drill bit's ability to drill hard material is greatly improved.

The advantage of the invention compared with the prior art is that the ground anchor pile adopts the way of butt welding of the taper pipe and the drill bit, so that different shapes of drill bits can be selected to adapt to different soil quality, and the flexibility and practicability are strong; Made of cast steel, the hardness is increased, and the anti-rust ability is enhanced, and the service life is greatly extended.

The present invention will be further described in detail below with reference to the accompanying drawings:

As shown in FIG. 1 and 2, a ground anchor pile of a solar photovoltaic power generation device is characterized in that it comprises a cone tube I and a drill bit 2, and the cone tube I and the drill bit 2 are welded, and the cone tube I is provided with Spiral piece 3.

As shown in FIG. 3 to FIG. 7 , the drill bit 2 has a pyramid shape, and may be a polygonal cone such as a triangular pyramid, a quadrangular pyramid, a pentagon cone or a hexagonal cone, or may be a cone. The drill bit 2 can also be provided with a spiral piece 4, so that the ground anchor pile and the soil are mutually squeezed, which is more powerful and firmer.

As shown in Figures 1 and 2, the tapered tube I is made of steel pipe and has a hardness of only 70 degrees Brine, but the drill bit 2 is made of cast steel and has a hardness of 160 degrees Brinell. The ability of hard objects is greatly improved.

As shown in Figures 1 and 2, the tapered pipe I of the spiral pile of the present invention is welded by a Q235B steel pipe and a cast steel drill bit 2, generally having a height of 1200-2000 mm and a diameter of 50-130 mm, which is selected according to different loads and corrosion requirements. Steel pipes of different thicknesses are made into spiral piles according to the hot dip galvanizing specifications of IS01461:1999. That is, the spiral piece 3 and the cone pipe I are integrally formed, without joints, using the MIG welding process, the soil will not be damaged when entering the ground, through the spiral piece The design of 3 makes the ground anchor pile and the soil mutually squeeze each other. The installation end is matched with the special pile driver to design the quick installation hole position, which is easy and quick to install, which saves time and piling cost, reduces the cost of foundation, can be moved at any time, and reduces the environment. The impact of reducing migration costs.

The above is only the embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent flow transformation made by the specification and the drawings of the present invention may be directly or indirectly applied to other related ones.
