Description

Photovoltaic power generation device capable of installing soft ground {PHOTOVOLTAIC POWER GENERATOR WITH SOFTGROUND INSTALLATION}

The present invention relates to a photovoltaic device, and in detail, by installing an elevating rod inside a screw pile, by raising the elevating rod while the screw pile is installed in the ground, and rotating a support pin installed outside the screw pile, It relates to a photovoltaic device capable of installing a soft ground to fix a screw pile in the form of a barb to the ground.

In general, in the case of constructing various architectural structures such as photovoltaic power generation devices or houses, in order to solidify the foundation, foundation work is performed by embedding PHC piles or piles for ground reinforcement such as H-beams in the ground. In addition, the construction of the ground reinforcement pile is a very important construction in constructing buildings and structures.

As a method of constructing the ground reinforcement pile, a pouring construction method and an excavation construction method have been introduced. The former pouring construction method is a method of punching and inserting a pile for ground reinforcement by raising and dropping a hammer of a heavy body using a winding rope installed on the upper part of a leader vertically installed on the crawler driving device, and compression of the compressor. This is a method of placing the pile for reinforcing the ground while raising and then lowering the hammer using air and inserting it into the ground.

In the latter excavation method, the ground is excavated by rotating the screw pile attached to the pile connection to form a pile hole, and then the screw pile is rotated in reverse to remove it from the drilled screw pile hole, and the ground reinforcement pile is placed in the pile hole. This is how to insert.

In addition, recently, instead of removing the screw pile after drilling a screw pile to form a hole and inserting the ground reinforcement pile in its place, a method of using the excavated screw pile in the ground as a ground reinforcement pile is also proposed. Has become.

On the other hand, when excavating screw piles into the ground, there are many differences in excavation time and workability in the ground depending on the shape of the screw piles, so in recent years the need for a shape of a screw pile that can excavate the ground most effectively has emerged. . A typical screw pile is a circular steel pipe with a spiral blade combined.

However, when the screw pile is excavated on a relatively hard ground such as rocky ground, there is a problem that it is difficult to excavate the screw pile because the tip of the circular steel pipe cannot easily penetrate the ground, and it is screwed on soft ground such as arable land or wetland. When the pile is excavated, the screw pile can be easily excavated, but there is a problem in that it is difficult to use the screw pile as a ground reinforcement pile because the support force of the screw pile is not large.

In order to solve this problem, Korean Patent Registration No. 10-0905069 (basic pile of the solar module holder) and No. 10-2002065 (solar power generation device installation screw pile) are disclosed.

The base pile of the solar module holder is fixedly installed on the ground or forest, as shown in FIG. 1, and the module holder 50 supporting the frame structure 20 on which a plurality of solar cell modules 40 are mounted. In the base pile of the solar module holder connected to the lower part and fixed to the forest or ground, horizontal mounting portions 64a and 64b are formed at the upper and lower ends of the body 62 having a predetermined length, respectively, and the horizontal mounting portion Between (64a, 64b), a plurality of support blades 66 are fixed to protrude along the longitudinal direction on the outer circumferential surface, and the base pile 60 is formed, and the mounting hole (H) of the place where the module holder 50 is mounted. After inserting in, it is fixedly installed through burial work.

The screw pile for installing the photovoltaic device includes a circular steel pipe 100 in the shape of a hollow tube vertically erected as shown in FIG. 2; A tip excavation block 200 coupled to a lower end of the circular steel pipe 100 and having an arrowhead-shaped cross-section whose width becomes narrower toward the lower side; A plurality of excavation blades 300 coupled to spirally surround the outer surface of the circular steel pipe 100 and arranged spaced apart in the vertical direction; Disc-shaped upper plate 400 coupled to the upper end of the circular steel pipe 100; Consists of including.

However, such a conventional screw pile increases the support by installing a rotating blade on the outside of the steel pipe, which is the body, and it is difficult to transport due to its relatively large volume, and the blade is deformed or damaged due to a load generated by the blade when inserted. have.

In addition, such a conventional screw pile has a problem in that the ground is disturbed by the blades, and thus the bearing power is relatively lowered.

7 to 10 are explanatory diagrams for explaining the installation process of the photovoltaic device capable of installing a soft ground according to the present invention.

First, the screw pile 10 is coupled to the tip of the equipment such as a hydraulic drill or a perforator using a flange (F).

In a state in which the coupling is completed, the screw pile 10 is inserted vertically into the ground while rotating as shown in FIG. 7.

When the insertion of the screw pile 10 is completed, as shown in FIG. 8, when the fixing cap 13 is separated from the body 11, the coil spring 16 is decompressed and the lifting rod 15 becomes the body ( 11) It rises from the inside.

As the lifting rod 15 is raised, the first inclined jaw 151 and the second inclined jaw 145 of the support pin 14 are in contact, so that the body blade 141 is centered on the hinge axis X by pressure. While rotating, it is maintained in a vertical state by the rubber band 17, and is then spread outward in an inclined state (about 20 to 45°). At this time, when the lifting rod 15 cannot be raised by the force of the coil spring 16 due to the pressure applied from the ground, a tool or equipment is coupled to the auxiliary screw groove of the lifting rod 15 to raise and lower by applying force from the outside. It is also possible to forcibly rotate the support pin 14 by lifting the rod 15.

On the other hand, when the support pin 14 is unfolded in the opposite direction of the insertion direction in the body 11, a force against the external force generated in the vertical upward direction is generated, so that the body 11 can be stably fixed, When the solar module 30 generates a force that rises from the ground, the body 11 stably fixes the module holder 20 so that the body 11 is pulled out and the module holder 20 and the solar module 30 It can prevent damaged wind damage.

By repeating the above process, all the screw piles 10 are inserted into the installation position.

Subsequently, as shown in FIG. 9, the ground into which each screw pile 10 is inserted is constantly dug and then concrete is poured into the space to integrate the concrete block 40 and the screw pile 10.

Thereafter, as shown in FIG. 1, the module holder 20 is connected to the flange F of the screw pile 10 and then the solar module 30 is installed on the module holder 20.
