Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a special tool for photovoltaic installation. Background Technology

[0002] Clean energy is gradually becoming an important new energy source globally. Driven by my country's carbon peaking and carbon standard compliance policies, solar photovoltaic power generation has become the main force of clean energy. For many years, the battery module support frame used in solar photovoltaic power stations has been a fixed steel structure support. However, when facing various complex terrains such as mountainous projects, fishery-solar complementary projects, and agricultural-solar complementary projects, the required support column lengths are not uniform due to the varying terrain elevations, which leads to difficulties in material processing and low efficiency. Therefore, adjustable column supports are now used to replace the fixed support materials. The adjustable bracket column has three bundled tube screws near the pipe opening when it leaves the factory, and a limit screw hole is set at the outer tube. During installation, when the column is adjusted to the design elevation, the limit hole is drilled to install the bolt, which strengthens the limit and tightens the bolt. However, the drilling of the column after installation has the following problems: 1. High safety risk: The drilling position of the high-pile photovoltaic bracket column is generally about 2 meters above the ground, which is a high-altitude operation. The drilling must be carried out using an operating platform. The construction work surface is about two meters high, and the terrain is uneven. If the operating platform is not installed firmly, the installed components and tools are easy to fall and injure people. Workers may also be at risk of falling from height due to improper protection and operation. 2. Low work efficiency: Drilling using an operating platform is cumbersome and time-consuming. It takes a lot of time to set up and move the operating platform and for workers to get on and off the operating platform. Each movable bracket needs to be drilled, which increases the workload, increases construction costs, reduces construction efficiency, and increases the labor intensity of workers. Summary of the Invention

[0003] The purpose of this utility model is to address the deficiencies of the existing technology by providing a special tool for opening pre-reserved holes in high-pile photovoltaic support columns. This tool can eliminate the need for setting up an operating platform, improve construction efficiency, reduce construction costs, and also reduce the safety risks of construction operations.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a special tool for opening reserved holes in high-pile photovoltaic support columns, including an impact drill, a long section steel pipe, an electrical switch, a conductive wire, a short section steel pipe, a swing assembly, and a hook. The electrical switch is installed at the bottom of the long section steel pipe. The impact drill is fixedly connected to the top of the long section steel pipe by a clamp. The conductive wire is connected between the impact drill and the electrical switch. The short section steel pipe is connected to the top of the long section steel pipe by a connecting device and extends vertically upward. The swing assembly is perpendicular to the upper end of the short section steel pipe. The overall extension direction of the swing assembly is on the same side as the drill bit of the impact drill. The inner side of the hook is connected to the outer side of the swing assembly. After the outer side of the hook extends outward, it bends horizontally inward to form a hook that can hook the outer sleeve of the photovoltaic support column.

[0005] A further technical solution of this utility model is: the long steel pipe and the connection section of the impact drill are bent sections that are pressed into a flat shape, and a drill rig reinforcing fixing plate is also included. One end of the drill rig reinforcing fixing plate is fixedly connected to one side of the bent section of the long steel pipe, and the other end of the drill rig reinforcing fixing plate extends backward along the surface of the impact drill and is then bent and attached to the rear end face of the impact drill and fixed to the rear end face of the impact drill by screws.

[0006] A further technical solution of this utility model is: the connecting device between the short section steel pipe and the long section steel pipe consists of two connecting steel plates and mating bolts and nuts. One connecting steel plate is connected to the top of the long section steel pipe, and the other connecting steel plate is connected to the bottom of the short section steel pipe. The two connecting steel plates are provided with corresponding connecting holes. The two connecting steel plates are mated and fixed by bolts and nuts.

[0007] A further technical solution of this utility model is as follows: the swing assembly includes an inner swing arm, an outer swing arm, and a spring. The inner swing arm is vertically connected to the upper end of the short section steel pipe, and the outer swing arm is hinged to the outside of the inner swing arm. A nut is fixedly connected to the top of the outer side of the inner swing arm, and a nut is also fixedly connected to the top of the inner side of the outer swing arm. The two ends of the spring are respectively connected to the two nuts. The inner side of the hook head is fixedly connected to the outer swing arm. When the hook head hooks the outer sleeve of the photovoltaic bracket column and pulls the long section steel pipe up and down, the hook head and the outer swing arm can swing up and down relative to the inner swing arm.

[0008] This utility model provides a special tool for drilling pre-reserved holes in high-pile photovoltaic support columns, which has the following advantages: Using this utility model eliminates the need for an operating platform, improving work efficiency and reducing safety risks during construction. During drilling, the hook can catch the outer sleeve of the photovoltaic support column, and the up-and-down movement of the long steel pipe hook and the outer swing arm allows for relative swinging of the inner swing arm, enabling appropriate adjustment of the impact drill's position and effectively ensuring drilling accuracy. Compared to existing construction methods, this utility model also boasts advantages such as simple structure, low manufacturing cost, and wide applicability, greatly improving construction efficiency and reducing worker labor intensity.

Detailed Implementation

[0014] like Figures 1 to 3 As shown, this utility model discloses a special tool for drilling pre-reserved holes in high-pile photovoltaic support columns, including an impact drill 4, a long steel pipe 1, an electric switch 2, a conductive wire 3, a short steel pipe 10, a swing assembly, and a hook 15. The impact drill 4 is a commercially available drill that can be used after charging for a period of time, or it can be connected to an external power source; its structure will not be described in detail here. In this utility model, the direction in which the drill bit 7 extends is defined as the front, and the opposite direction is defined as the rear; the end closest to the central axis of the long steel pipe 1 and the short steel pipe 10 is the inner side, and the end furthest from the central axis of the long steel pipe 1 and the short steel pipe 10 is the outer side.

[0015] like Figure 1 , Figure 2 As shown, an electrician's switch 2 is installed near the bottom of the long steel pipe 1. An impact drill 4 is fixedly connected to the long steel pipe 1 near the top via a clamp 5. A conductive wire 3 connects the impact drill 4 and the electrician's switch 2, and is fixed to the surface of the long steel pipe 1 via the clamp 5. Pressing the electrician's switch 2 turns on the impact drill 4 for drilling operations. The connection section between the long steel pipe 1 and the impact drill 4 is a flattened curved section. Flattening the connection section makes the connection between the long steel pipe 1 and the impact drill 4 more stable. Alternatively, as a variation of this invention, a bent arc-shaped steel plate can be welded to the upper end of the long steel pipe 1, and the top of the arc-shaped steel plate can be connected to the short steel pipe 10 via a connecting device. The special tool of this utility model also includes a drill rig reinforcing and fixing plate 17. One end of the drill rig reinforcing and fixing plate 17 is fixedly connected (i.e. welded) to one side of the bent section of the long steel pipe 1. The other end of the drill rig reinforcing and fixing plate 17 extends backward along the surface of the impact drill 4 and is then bent and attached to the rear end face of the impact drill 4 and fixed to the rear end face of the impact drill 4 by screws 6. The drill rig reinforcing and fixing plate 17 can stably connect the impact drill 4 to the long steel pipe 1.

[0016] like Figure 1 , Figure 2As shown, the short section steel pipe 10 is connected to the top of the long section steel pipe 1 via a connecting device and extends vertically upwards. The connecting device between the short section steel pipe 10 and the long section steel pipe 1 consists of two connecting steel plates 8 and mating bolts and nuts 9. One connecting steel plate 8 is welded to the top of the long section steel pipe 1, and the other connecting steel plate 8 is welded to the bottom of the short section steel pipe 10. The two connecting steel plates 8 have corresponding connecting holes. When the bottom of the short section steel pipe 10 is connected to the top of the long section steel pipe 1, the two connecting steel plates 8 are mated and fixed by bolts and nuts 9. Both the long section steel pipe 1 and the short section steel pipe 10 are galvanized steel pipes with a diameter of 25mm.

[0017] like Figures 1 to 3 As shown, the swing assembly is perpendicular to the upper end of the short steel pipe 10. The overall extension direction of the swing assembly is on the same side as the drill bit 7 of the impact drill 4. The inner side of the hook head 15 is connected to the outer side of the swing assembly. The outer side of the hook head 15 first extends outward and then bends horizontally inward to form a hook that can hook onto the outer sleeve of the photovoltaic support column (not shown in the figure). Figure 3 As shown, the hook 15 is formed by bending a 6mm diameter steel bar. In this embodiment, the swing assembly includes an inner swing arm 16, an outer swing arm 14, and a spring 13. The inner swing arm 16 and the outer swing arm 14 are two thin steel plates or galvanized iron sheets, respectively. The inner swing arm 16 is vertically connected to the upper end of the short steel pipe 10 by welding. The outer swing arm 14 is hinged to the outside of the inner swing arm 16. The outer swing arm 14 can swing up and down relative to the inner swing arm 16 within a certain angle (within a range of 10 degrees) around the hinge axis 11. A nut 12 is fixedly connected to the top of the outer side of the inner swing arm 16, and a nut 12 is also fixedly connected to the top of the inner side of the outer swing arm 14. The two ends of the spring 13 are respectively connected to the two nuts 12. The inner side of the hook head 15 is fixedly connected to the outer swing arm 14 by welding. When the hook head 15 hooks the outer sleeve of the photovoltaic bracket column and pulls the long section steel pipe 1 up and down, the hook head 15 and the outer swing arm 14 can swing up and down relative to the inner swing arm 16. The spring 13 can make the outer swing arm 14 return to its original state after swinging relative to the inner swing arm 16.

[0018] Before use, check that all parts of the tool are properly connected. Once you are sure there are no problems, turn on the impact drill 4 for a test drill. When drilling, first stand the tool upright, hook the fixing hook 15 onto the intended hole position on the outer sleeve of the support column, align the impact drill 4 head 7 with the reserved bolt hole, then turn on the power switch 2 and start the impact drill 4 to drill. After the reserved hole is drilled through, slowly pull out the drill bit 7 and move the impact drill 4 to the next reserved hole to drill.

[0019] The above embodiments are merely preferred embodiments of this utility model. The structure of this utility model is not limited to the forms listed in the above embodiments. Any modifications, equivalent substitutions, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
