Description

Technical Field

[0001] This utility model relates to the field of new energy photovoltaic cast-in-place pile foundation technology, and has a hole cleaning device for photovoltaic bracket cast-in-place pile foundation. Background Technology

[0002] With the increasing number of photovoltaic power stations, land resources with good sunshine, flat terrain, and favorable construction conditions are becoming increasingly scarce. Land with less favorable construction conditions, such as agriculture, lakes, and mountains, is gradually becoming the land resources for photovoltaic power station construction, especially in mountainous areas, where construction has been gradually increasing in recent years. Currently, during the pile foundation construction of photovoltaic power plants, the mountainous climate is changeable, with frequent thunderstorms, and the geology is mostly weathered rock and silt layers, which are prone to hole collapse after rain. Traditional electric clay diggers are inconvenient to move in mountainous areas and are prone to over-excavation. Inventing a convenient, simple, and fast manual soil removal tool can improve work efficiency and better control the hole depth. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a hole cleaning device for the foundation of cast-in-place piles for photovoltaic brackets, which overcomes the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hole cleaning device for the foundation of photovoltaic bracket cast-in-place piles, including a horizontal rotating handle, a longitudinal connecting rod and a single-blade drill bit with helical blades. The upper end of the longitudinal connecting rod is fixed to the middle of the horizontal rotating handle and the lower end is connected to the single-blade drill bit. The outer edge of the blade of the single-blade drill bit is provided with an anti-slip guard.

[0005] Optionally, the single-piece drill bit is a single-piece manganese steel drill bit.

[0006] Optionally, the anti-slip edge is an iron wire welded to the edge of the blade of the single drill bit.

[0007] Optionally, it also includes a horizontal connecting rod, with a longitudinal insert at the center of the horizontal connecting rod, and a hole through which the horizontal rotating handle passes. The lower end of the longitudinal insert is inserted into the hole, and the longitudinal insert is slidably connected to the hole.

[0008] Both ends of the horizontal connecting rod extend horizontally outward from both sides of the horizontal rotating handle. Both ends of the horizontal connecting rod are connected to a bent rod. The bent rod is composed of two straight rods connected end to end. One of the straight rods is located on the side of the horizontal rotating handle, and the other straight rod is located below the horizontal rotating handle with its end facing the longitudinal connecting rod. The straight rod below the horizontal rotating handle on the bent rod has an elongated hole. The two ends of the elongated hole extend towards the outer end of the horizontal rotating handle and the longitudinal connecting rod, respectively. A support plate passes through the elongated hole and is slidably connected to the elongated hole. Each end of the straight rod near the elongated hole has a set screw, which limits the position of the support plate.

[0009] The lower end of the support plate extends to the lower end of the single drill bit.

[0010] Optionally, the lower part of the support plate has a V-shaped support frame, which consists of two openable and closable plates connected by hinges.

[0011] Optionally, the end of the straight rod located below the horizontal rotating handle extends obliquely upward.

[0012] Optionally, the bottom surface of the V-shaped support frame is rough.

[0013] Optionally, the blades of the single drill bit have locking interfaces that correspond one-to-one with the support plate, and the support plate can extend into the locking interfaces.

[0020] like Figure 1 As shown, this utility model provides a hole-cleaning device for the foundation of photovoltaic bracket cast-in-place piles, including a horizontal rotating handle 1, a longitudinal connecting rod 2, and a single-blade manganese steel drill bit 3 with helical blades. The upper end of the longitudinal connecting rod 2 is fixed to the middle of the horizontal rotating handle 1, and the lower end is connected to the single-blade manganese steel drill bit 3. An anti-slip guard 3-1 is provided on the outer edge of the blade of the single-blade manganese steel drill bit 3. The anti-slip guard 3-1 is an 8mm iron wire welded to the edge of the blade of the single-blade manganese steel drill bit 3. Both the horizontal rotating handle 1 and the longitudinal connecting rod 2 are made of 6cm steel pipes. The horizontal rotating handle 1 and the longitudinal connecting rod 2 are welded together, and the longitudinal connecting rod 2 is fixed to the single-blade manganese steel drill bit 3 by a pin.

[0021] When in use, manually turn the horizontal rotation handle 1 to drill the single manganese steel drill bit 5 into the soil. Specific Implementation Method Two

[0023] like Figure 2 As shown, this embodiment adds a support structure based on the first specific embodiment to facilitate support for the drill bit during operation and ensure that the force is applied vertically downward. The support structure includes a horizontal connecting rod 5, a longitudinal insert rod 4 at the center of the horizontal connecting rod 5, and an insertion hole through which the horizontal rotating handle passes in the longitudinal connecting rod 2. The lower end of the longitudinal insert rod 4 is inserted into the insertion hole, and the longitudinal insert rod 4 is slidably connected to the insertion hole.

[0024] The two ends of the horizontal connecting rod 5 extend horizontally to both sides of the horizontal rotating handle 1. Both ends of the horizontal connecting rod 5 are connected to a bent rod 6. The bent rod 6 is composed of two straight rods connected end to end. One straight rod is located on the side of the horizontal rotating handle 1, and the other straight rod is located below the horizontal rotating handle 1 with its end facing the longitudinal connecting rod 2. The straight rod below the horizontal rotating handle 1 on the bent rod 6 has an elongated hole 6-1. The two ends of the elongated hole 6-1 extend towards the outer end of the horizontal rotating handle 1 and the longitudinal connecting rod 2, respectively. A support plate 7 passes through the elongated hole 6-1 and is slidably connected to the elongated hole 6-1. The straight rod has a set screw 6-2 near both ends of the elongated hole 6-1. The set screw 6-2 limits the support plate 7.

[0025] The lower end of the support plate 7 extends to the lower end of the single manganese steel drill bit 5.

[0026] When in use, slide the support plate 7 along the long hole 6-1 to a position away from the single manganese steel drill bit 5, and make the lower end of the support plate 7 stand on the soil surface. Then, manually rotate the horizontal rotation handle 1 to make the single manganese steel drill bit 5 drill into the soil. The support plate 7 supports the drill bit and ensures that the direction of the drill bit drilling into the soil remains vertical.

[0027] The lower part of the support plate 7 has a V-shaped support frame 7-1, which consists of two openable plates connected by hinges. When supporting, the plates are opened to form a V-shape, increasing the contact area between the bottom of the support plate and the soil surface, making the support more stable. When storing, the plates can be closed.

[0028] The end of the straight rod located below the horizontal rotating handle 1 extends upward at an angle. When the support plate 7 slides along the elongated hole 6-1 to near the longitudinal connecting rod 2, the support plate 7 can be lifted upward due to the upward angle of the end of the straight rod, thereby detaching it from the soil surface for easy storage.

[0029] The bottom surface of the V-shaped support frame 7-1 is rough.

[0030] The blades of the single-blade manganese steel drill bit 5 have corresponding locking interfaces 3-2 that correspond one-to-one with the support plate 7, allowing the support plate 7 to extend into the locking interfaces 3-2. The locking interface 3-2 and the support plate 7 further facilitate the storage of the device, reduce storage space, and facilitate transportation.

[0031] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
