Specific embodiments:

[0025] Such as Figures 1-4As shown, a photovoltaic bored pile hole cleaning device includes a cylinder 1, and an adjustable cleaning groove 2 is provided at the lower end of the cylinder 1. The cleaning groove 2 is used to clean the debris in the pile hole 3. The two cleaning grooves 2 can extend outward away from the central axis of the cylinder 1 to adapt to pile holes 3 of different diameters and clean them. The cylinder body 1 is sleeved on the supporting mechanism 4. Before the hole cleaning work is carried out, the supporting mechanism 4 is first fixed outside the pile hole 3, and then the cylinder body 1 is sleeved on the supporting mechanism 4 to position and reinforce the cylinder body 1 to improve the overall stability of the device. An adjusting mechanism 5 connected with the cleaning groove 2 is provided on the cylinder body 1, and the adjusting mechanism 5 is used to control and adjust the sliding of the cleaning groove 2. A handle 8 is fixedly connected to the upper end surface of the cylinder body 1. After that, after the lower end of the cylinder body 1 enters the pile hole 3, the cylinder body 1 is rotated by holding the handle 8 to rotate the cleaning groove 2 accordingly, and the debris collapsed to the bottom of the pile hole 3 is cleaned and collected. The two cleaning grooves 2 are moved away from the central axis of the cylinder body 1 by operating the adjusting mechanism 5, so that the side of the cleaning groove 2 away from the cylinder body 1 contacts the inner wall of the pile hole 3, and then the cylinder body 1 is rotated to make the cleaning groove 2 continue to clean and collect the debris collapsed to the bottom of the pile hole 3. Through the rotation cooperation of the adjusting mechanism 5, the cleaning groove 2 and the cylinder body 1, pile holes 3 with different diameters can be cleaned.

[0026] like Figures 1-4 As shown, the cross section of the cleaning groove 2 is fan-shaped and one side wall of the cleaning groove 2 is open, which is used to rotate and clean the collected debris. The upper end surface of the cleaning groove 2 is fixedly connected to a slider 6. The cylinder 1 is hollow inside and a long groove 7 connected to the inside is opened at the lower end. The slider 6 slides in the long groove 7; the adjustment mechanism 5 includes a first rotating rod 51 that is rotatably connected to the cylinder 1 along the length direction of the long groove 7, and a first pulley 52 is fixedly connected to the middle of the first rotating rod 51. The first rotating rod 51 is provided with external threads with opposite patterns on both sides of the first pulley 52. The slider 6 is connected to the cylinder 1 along the length direction of the long groove 7. The adjusting mechanism 5 is threadedly connected to the first rotating rod 51 and the two sliders 6 are located on both sides of the first pulley 52; the adjusting mechanism 5 also includes two parallel vertical plates 53 fixedly connected to the upper end surface of the cylinder 1, the two vertical plates 53 are rotatably connected to the second rotating rod 54, the second rotating rod 54 is fixedly connected to the second pulley 55, the first pulley 52 and the second pulley 55 are connected by a belt 56, the upper end of the cylinder 1 is provided with an opening connected to the interior for the belt 56 to pass through, one end of the second rotating rod 54 passes through the vertical plate 53 and is provided with a turning handle 57. By turning the turning handle 57, the second rotating rod 54 and the second pulley 55 are driven to rotate, and since the first pulley 52 and the second pulley 55 are connected by the belt 56, the first pulley 52 and the first rotating rod 51 rotate accordingly, and the slider 6 can move along the length direction of the long groove 7 under the restriction of the long groove 7, the two sliders 6 move away from each other, and then the two cleaning grooves 2 move away from each other and contact the inner wall of the pile hole 3, so that the cleaning device can adapt to and clean pile holes of different diameters.

[0027] like Figures 1-4As shown, a slope 21 is provided at the lower end of the opening of the cleaning groove 2. When the rotating cylinder 1 rotates, it helps the debris at the bottom of the pile hole 3 to enter the cleaning groove 2. A plurality of cleaning teeth 22 are fixedly connected at equal intervals at the lower end of the opening of the cleaning groove 2. The provision of the cleaning teeth 22 helps the cleaning groove 2 to clean the debris firmly adhered to the pile hole 3.

[0028] As Figures 1-4 shown, the support mechanism 4 includes a positioning ring 41. At least three adjustable support frames 42 are fixedly connected to the positioning ring 41 along the circumferential direction. After the support mechanism 4 is installed, the cylinder 1 is sleeved in the positioning ring 41. A flange 9 is provided on the outer side wall of the upper end of the cylinder 1 to prevent the cylinder 1 from completely passing through the positioning ring 41. By providing the support mechanism 4, the stability of the device during use can be improved.

[0029] As Figures 1-4 shown, the support frame 42 includes a connecting plate 421 fixedly connected to the side wall of the positioning ring 41 and a plug rod 422 sleeved on the connecting plate 421. The plug rod 422 is used to insert into the surrounding ground of the pile hole 3. A plurality of slots 423 are provided at equal intervals along the length direction of the plug rod 422. It also includes a plug board 424 that can be inserted into the slots 423. First, roughly align the center of the positioning ring 41 with the center of the pile hole 3, mark the position corresponding to the through connection of the connecting plate 421 and the plug rod 422, remove the positioning ring 41 and insert the plug rod 422 at the marked position, then connect each connecting plate 421 to each plug rod 422 through connection, insert the plug board 424 through to the adjacent slot 423 below the connecting plate 421 and make at least one end of the plug board 424 located outside the slot 423, so that the upper end surface of the plug board 424 contacts the lower end surface of the connecting plate 421. The plug board 424 supports the connecting plate 421 and can also adjust the position, thereby adjusting the fixed height of the positioning ring 41.

[0030] As Figures 1-4 shown, a conical head 425 is fixedly connected to the lower end of the plug rod 422, which helps the plug rod 422 to insert into the ground. A contact plate 426 is fixedly connected above the connection between the conical head 425 and the plug rod 422. The lower end surface of the contact plate 426 is used to contact the ground to prevent the plug rod 422 from continuously inserting into the ground under the action of external force.

[0031] The working principle of a hole cleaning device for a photovoltaic cast-in-place pile in this embodiment is as follows: During use, first, the support mechanism 4 is positioned and installed. The cylinder body 1 is sleeved in the positioning ring 41, and the lower end of the cylinder body 1 enters the pile hole 3. By rotating the turning handle 57, the cleaning groove 2 contacts the inner wall of the pile hole 3. One worker holds the positioning ring 41 by hand, and another worker pulls out all the plug plates 424. The worker holding the positioning ring 41 slowly lowers the positioning ring 41. During the lowering process, the other worker holds the grip 8 and rotates the cylinder body 1, so that the cleaning groove 2 scrapes off the debris adhered to the inner wall of the pile hole 3 and drops to the bottom of the pile hole 3. After the lower end of the cleaning groove 2 contacts the bottom of the pile hole 3, continue to rotate the cylinder body 1 to clean the debris at the bottom of the pile hole 3 with the cleaning groove 2. Then rotate the adjusting turning handle 57 to make the two cleaning grooves 2 approach each other, and continue to rotate the cylinder body 1 to make the two cleaning grooves 2 continue to clean the debris at the bottom of the pile hole 3. Pull out the cylinder body 1 and clean the debris collected in the cleaning groove 2. Observe the amount of debris at the bottom of the pile hole 3 to judge whether further cleaning is required. If further cleaning is needed, repeat the above steps to clean the pile hole 3. During the cleaning process, the positioning ring 41 and the support frame 42 cooperate to always limit the position of the cylinder body 1, thereby improving the overall stability during cleaning and being able to adapt to pile holes 3 with different diameters. If there is only one worker, after pulling out the plug plate 424, lift the positioning ring 41 to a suitable position, then insert the plug plate 424 into the slot 423 at the suitable position, and then rotate the cylinder body 1 to make the cleaning groove 2 clean the inner wall of the pile hole 3. Repeat this step to scrape off the debris on the inner wall of the pile hole 3, and then clean the bottom of the pile hole 3.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
