[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a new power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy.

[0003] When constructing a solar photovoltaic power generation system in a mountainous environment, it is typically necessary to drive multiple ground piles into the ground. These piles are then used to install photovoltaic racks, and finally, to mount solar panels on the racks. These piles are typically screw piles, with a drill bit at one end and spiral blades wrapped around the outer wall. Traditionally, the installation method involves using ground drilling equipment to clamp the end of the pile away from the drill bit and rotate it into the ground.

[0004] However, when driving screw piles in mountainous environments, the surface rock and soil is softer than the deep rock and soil, and the outer diameter of the screw piles is smaller, which makes it easy for the surface rock and soil to have insufficient restraint on the screw piles, resulting in unstable installation of the screw piles.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0018] The embodiment of the present application discloses a screw pile for a mountain photovoltaic support. Referring to Figure 1 、 Figure 2 and Figure 3 , it includes a screw pile body 1. One end of the screw pile body 1 is integrally fixed with a drill bit for drilling into the ground, and the other end of the screw pile body 1 is coaxially welded and fixed with a flange 2. A plurality of through holes 21 are formed in the flange 2, and a positioning column for plugging and cooperating with the through holes 21 is installed on the drilling equipment. One end of the screw pile body 1 close to the drill bit is welded and fixed with a screw blade 11, and a hoop 3 for burying into the surface layer is coaxially sleeved on the end of the screw pile body 1 far from the screw blade 11. A plurality of connecting plates 4 are circumferentially connected between the screw pile body 1 and the hoop 3 around the screw pile body 1, and a filler cavity for backfilling rock and soil is formed between two adjacent connecting plates 4.

[0019] In the embodiment of the present application, construction workers can install the screw pile body 1 on the drilling equipment, and insert the positioning column on the drilling equipment into the through holes 21 of the flange 2, and then start the drilling equipment to rotate and drive the screw pile body 1 into the ground. In order to facilitate driving the hoop 3 into the surface layer, construction workers can dig a pit for accommodating the hoop 3 at the piling position before driving the screw pile body 1. When the screw pile body 1 is driven into the ground, the hoop 3 drills into the pit and is in close contact with the inner side wall of the pit. Since the outer diameter of the hoop 3 is larger than the outer diameter of the screw pile body 1, when driving the screw pile body 1, the hoop 3 can increase the binding force of the surface rock and soil on the screw pile body 1, thereby improving the installation stability of the screw pile body 1. Backfilling the excavated rock and soil into the filler cavity and tamping it can further improve the installation stability of the screw pile body 1.

[0020] Specifically, the connecting plate 4 includes a fixed plate 41 and a moving plate 42 slidably arranged on the fixed plate 41 along the radial direction of the screw pile body 1. The fixed plate 41 is welded to the outer wall of the screw pile body 1. The hoop 3 is circumferentially divided into a plurality of baffles 31, and the plurality of baffles 31 are welded to the moving plate 42 one by one. A first limiting member 5 for restricting the movement of the moving plate 42 relative to itself is installed on the fixed plate 41. The first limiting member 5 includes a first limiting bolt. A groove for accommodating the moving plate 42 is formed at one end of the fixed plate 41 away from the screw pile body 1. A plurality of first threaded holes are formed at intervals on the side wall of the moving plate 42 along its moving direction. A limiting hole communicating with the groove is formed at one end of the side wall of the fixed plate 41 away from the screw pile body 1. The first limiting bolt passes through the limiting hole and is threadedly connected to the first threaded hole.

[0021] In the embodiment of the present application, for areas where the surface soil and rock are relatively soft, the moving plate 42 can be slid to extend the overall length of the connecting plate 4, and the movement of the moving plate 42 can be restricted by the first limiting bolt, thereby increasing the outer diameter of the hoop 3. In this way, it can be ensured that the surface soil and rock can restrain the screw pile body 1, further improving the installation stability of the screw pile body 1.

[0022] In order to improve the overall stability between the plurality of baffles 31, an elastic connecting piece 6 is movably arranged between two adjacent baffles 31. Installation grooves for inserting the connecting piece 6 are provided at both ends of the baffle 31. A second limiting member 7 for restricting the movement of the connecting piece 6 is installed on the baffle 31. The second limiting member 7 includes a second limiting bolt. A second threaded hole communicating with the installation groove is formed on the side wall of the baffle 31. The second limiting bolt is threadedly connected to the second threaded hole and is in movable abutment with the connecting piece 6.

[0023] In the embodiment of the present application, the connecting piece 6 can be made of a metal elastic sheet. When the construction worker slides the moving plate 42 and increases the length of the connecting plate 4, the distance between two adjacent baffles 31 will also expand. Since both ends of the connecting piece 6 are respectively inserted into the corresponding installation grooves, the construction worker can tighten the second limiting bolt to abut against the connecting piece 6, so that the plurality of baffles 31 can form an integral body through the connecting piece 6, further improving the overall stability between the plurality of baffles 31.

[0024] In order to improve the installation stability of the screw pile body 1, a plurality of rotating rods 8 are circumferentially arranged on the outer wall of the flange plate 2. One end of the rotating rod 8 is rotatably arranged on the outer wall of the flange plate 2, and a support plate 81 for fitting the ground surface is rotatably arranged at the other end of the rotating rod 8. A positioning screw 82 for driving into the ground is installed on the support plate 81.

[0025] In the embodiment of the present application, the construction worker can use relevant equipment to rotate the positioning screw 82 into the ground and firmly nail the support plate 81 to the ground surface, thereby further improving the installation stability of the screw pile body 1.

[0026] Further, the screw pile body 1 is a hollow steel pipe, and the inner ring side of the flange 2 is communicated with the inside of the screw pile body 1. An air vent 12 communicated with its own inside is opened on the outer wall of one end of the screw pile body 1 away from the flange 2.

[0027] In the embodiment of the present application, using a hollow steel pipe can reduce the overall weight of the screw pile body 1 so that the screw pile body 1 can be installed on the earth drilling equipment. When it rains, the accumulated water inside the screw pile body 1 can be drained out through the air vent 12.

[0028] In other embodiments of the present application, after the screw pile body 1 is installed, construction workers can fill the inside of the screw pile body 1 with concrete to increase the installation stability of the screw pile body 1.

[0029] The implementation principle of the screw pile for a mountain photovoltaic support in the embodiment of the present application is as follows: Before driving the screw pile body 1, construction workers need to dig a hole at the piling position for accommodating the ferrule 3, and then use the earth drilling equipment to rotate and drive the screw pile body 1 into the ground. When the screw pile body 1 is driven into the ground, the ferrule 3 drills into the hole and is in close contact with the inner side wall of the hole. Since the outer diameter of the ferrule 3 is larger than the outer diameter of the screw pile body 1, when driving the screw pile body 1, the binding force of the surface rock and soil on the screw pile body 1 can be increased through the ferrule 3, thereby improving the installation stability of the screw pile body 1. Backfilling the excavated rock and soil into the filler cavity and tamping it can further improve the installation stability of the screw pile body 1.
