Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction, and in particular to a hole cleaning tool for photovoltaic pile foundations. Background Technology

[0002] Photovoltaic (PV) foundations are the infrastructure components used to support and secure solar photovoltaic (PV) panels, typically used in large-scale PV power plants or distributed PV power generation systems. The construction process involves drilling holes in the ground, installing the reinforcing cage, and finally pouring concrete to complete the PV foundation construction.

[0003] However, after the pile hole is drilled, it needs to be cleaned and the depth of the pile hole needs to be accurately measured. If the pile hole depth does not meet the standard, it is necessary to drill again. Currently, the cleaning and secondary drilling processes are usually carried out using cleaning and drilling machinery, which easily leads to hole collapse, affecting construction efficiency and pile quality, and needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hole cleaning tool for photovoltaic pile foundations, which improves construction efficiency and pile quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hole cleaning tool for photovoltaic pile foundations, comprising: The drill rod is set vertically and is used to insert into the pile hole; A spiral drill bit is arranged in a spiral shape at the lower end of the drill rod; The handle is horizontally positioned at the upper end of the drill rod and is for the worker to hold.

[0006] In a preferred embodiment, the present invention can be further configured such that: the drill rod includes multiple rod sections, the rod sections are threadedly connected, and the lowest rod section is threadedly connected to the auger drill bit.

[0007] In a preferred embodiment, the present invention may be further configured to include a support frame that spans the pile hole.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example 1: like Figure 1 As shown, a hole cleaning tool for photovoltaic pile foundation includes a drill rod 1, a spiral drill bit 2, and a handle 3.

[0017] like Figure 1 As shown, the drill rod 1 is vertically positioned and is used to insert into the pile hole. The drill rod 1 includes multiple rod sections 11, which are threaded together.

[0018] like Figure 1 As shown, the auger drill bit 2 is spirally arranged at the lower end of the bottom rod 11 and is threadedly connected to the bottom rod 11. The handle 3 is horizontally arranged at the upper end of the drill rod 1 and is for the worker to hold.

[0019] When it is necessary to clean the pile hole, the rod body 11 can be connected according to the depth of the pile hole to assemble drill rods 1 of different lengths. Then, the auger drill bit 2 is installed at the bottom of the drill rod 1 to complete the assembly of the entire hole cleaning tool.

[0020] Then, drill rod 1 and auger bit 2 are inserted into the pile hole, and handle 3 is used to rotate drill rod 1. At this time, drill rod 1 drives auger bit 2 to rotate synchronously, using auger bit 2 to support the soil. Then, drill rod 1 and auger bit 2 are controlled to move upward to lift the soil and complete the cleaning of the pile hole.

[0021] When secondary drilling of the pile hole is required, the handle 3 can be pressed down and rotated at the same time to drill the pile hole. Then, the soil and debris in the pile hole are cleaned to complete the secondary drilling and hole cleaning.

[0022] Therefore, by setting up a drill rod 1 with a spiral drill bit 2, the rotation of the spiral drill bit 2 can support the soil and debris inside the existing pile hole, while the drilling rod 1 can be used to clean up the soil and debris. Furthermore, the drilling rod 1 can be pressed downwards to perform secondary drilling using the spiral drill bit 2. These two construction processes are relatively convenient, improving construction efficiency, while minimizing disturbance to the soil layer to avoid hole collapse and ensure the quality of the pile.

[0023] Example 2: like Figure 2 , Figure 3 As shown, a hole cleaning tool for photovoltaic pile foundations also includes a support frame 4, which spans across the pile hole. The support frame 4 includes a pair of columns 41 and a crossbeam 42, with the crossbeam 42 horizontally positioned above the pair of columns 41 and through which the crossbeam 42 passes.

[0024] like Figure 2 , Figure 3 As shown, the column 41 includes a vertical rod 43 and a pair of legs 44. The vertical rod 43 is set vertically, and the pair of legs 44 are rotatably connected to the lower end of the vertical rod 43.

[0025] like Figure 2 , Figure 3 As shown, the crossbeam 42 includes a pair of beams 45, and a clamp 46 is provided between the pair of beams 45 to tighten the outer wall of the drill rod 1. One clamp 46 has a hook 47 at its end, and the other clamp 46 has a hole 48 at its end for the hook 47 to pass through.

[0026] When hole cleaning or drilling is required, a pair of clamps 46 can be fastened to the outer wall of the drill rod 1, and the hooks 47 can be passed through the holes 48 to assemble and connect the crossbeam 42 with the drill rod 1. Then, the support frame 4 is placed on the ground, and the legs 44 are turned outward so that the legs 44 support the ground and the entire support frame 4 spans the pile hole.

[0027] Subsequently, during the cleaning and drilling process of drill rod 1, the support frame 4 can be used to support drill rod 1, ensuring that drill rod 1 can move vertically downward stably, thereby achieving vertical cleaning and drilling of the pile hole and ensuring the quality of the pile hole.

[0028] Example 3: like Figure 4 , Figure 5 As shown, a hole cleaning tool for a photovoltaic pile foundation has a collar 5 rotatably connected to a column 41, a frame 6 on the collar 5, and a collection bag 7 located below the auger bit 2 after rotation on the frame 6.

[0029] like Figure 4 , Figure 5 As shown, frame 6 includes a support rod 61, insertion rods 62, and insertion tube 63. The support rod 61 can be a chain or a steel rod, and is bent into a ring shape. The insertion rods 62 are located at both ends of the support rod 61 and are interlocked. The insertion tube 63 is for inserting the interlocked pair of insertion rods 62. The outer wall of the insertion rods 62 is provided with a locking hook 64, and the insertion tube 63 is provided with a locking hole 65 for the locking hook 64 to pass through.

[0030] When cleaning the soil and debris in the pile hole, the support rod 61 can be bent and arranged in a ring shape, and then the collection bag 7 is fixed to the support rod 61. Then, the insertion rods 62 on the support rod 61 are interlocked and inserted into the insertion tube 63. At this time, the insertion rods 62 are fixed by the cooperation of the locking hook 64 and the locking hole 65, thus completing the assembly of the collection bag 7.

[0031] When the drill rod 1 and the auger bit 2 are cleaning and drilling, the control collar 5 rotates so that the collection bag 7 is located outside the column 41. After the soil is lifted, the control collar 5 rotates in the opposite direction so that the collection bag 7 is located below the auger bit 2, so that the soil is loaded into the collection bag 7, realizing the directional collection of soil in the pile hole, protecting the hygiene of the surrounding environment, and the soil can also be taken to the laboratory for testing.

[0032] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
