[0002] Solar energy, as an inexhaustible and clean energy source, is one of the main alternatives to traditional fossil fuels. Mountainous areas typically have higher altitudes and wider views, allowing them to receive more solar radiation and thus have richer solar energy resources. Building photovoltaic power stations on non-arable and non-ecological mountainous land can achieve efficient use of land resources and increase the economic value of the land.

[0003] Drilled piles are a common type of pile foundation for photovoltaic support systems. Due to the rugged terrain and complex geology of mountainous areas, the construction of photovoltaic support pile foundations in mountainous areas mainly uses lightweight down-the-hole drills and photovoltaic mini-hole drills. However, after drilling, there is often a lot of slag in the pile hole. In order to ensure the quality of the pile foundation pouring, it is necessary to clean the slag in the pile hole. The traditional cleaning method is mostly manual slag removal. However, manual slag removal is time-consuming and labor-intensive, has low cleaning efficiency, is difficult to remove fine particles of slag, and is prone to hole collapse during the cleaning process, thus affecting the quality of the pile foundation construction. Utility Model Content

The bend pipe section is connected to the upper end of the straight pipe section and is set outside the pile hole. The connecting rod is fixedly installed above the bend pipe section, and the operating rod is fixedly installed at the upper end of the connecting rod.

[0007] One end of the control lever is equipped with a handle-type press-type air valve. The air outlet pipe runs through the bend section and is set inside the straight section. The inlet and outlet ends of the handle-type press-type air valve are connected to the air supply pipe and the air outlet pipe, respectively. The air supply pipe is connected to a high-pressure air source.

[0008] In one alternative, the slag outlet of the bend section faces away from the handle-type press valve, and the slag outlet of the bend section is tilted upwards.

[0027] Traditional manual cleaning methods for removing floating slag from the holes of photovoltaic support pile foundations are time-consuming, labor-intensive, inefficient, and difficult to remove fine particles of floating slag. They also pose a risk of hole collapse during the cleaning process, which can affect the quality of pile foundation construction.

[0028] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.

[0029] In some implementations, please refer to Figures 1-2 A device for rapid hole cleaning of photovoltaic support pile foundations in mountainous areas is provided, comprising a slag discharge pipe 1, a connecting rod 2, an operating rod 3, a handle-type press-type air valve 4, an air outlet pipe 5, an air supply pipe 6, and a high-pressure air source 7. The slag discharge pipe 1 includes a straight pipe section 11 and a bent pipe section 12. The straight pipe section 11 is at least partially inserted into the pile hole 10 and extends to the bottom of the pile hole 10. The bent pipe section 12 is connected to the upper end of the straight pipe section 11 and is located outside the pile hole 10. The straight pipe section 11 and the bent pipe section 12 are stainless steel pipes connected by welding. The outer diameter of the straight pipe section 11 matches the inner diameter of the pile hole 10. The connecting rod 2 is fixedly installed above the bent pipe section 12, and the operating rod 3 is fixedly installed on the upper end of the connecting rod 2. A handle-type press-type air valve 4 is installed at one end of the operating rod 3. The air outlet pipe 5 passes through the bent pipe section 12 and is located inside the straight pipe section 11. The inlet and outlet ends of the handle-type press-type air valve 4 are connected to the air supply pipe 6 and the air outlet pipe 5, respectively. The air supply pipe 6 is connected to the high-pressure air source 7.

[0030] In this way, high-pressure air is supplied from the high-pressure air source 7 to the air outlet pipe 5 located inside the straight pipe section 11 of the slag outlet pipe 1 through the air supply pipe 6. This allows the floating slag in the pile hole 10 to be guided and transported out of the pile hole 10 under the action of high-pressure air through the slag outlet pipe 1, so as to achieve rapid and effective cleaning of the floating slag in the pile hole 10. It can effectively clean fine particles of floating slag. The cleaning operation is time-saving and labor-saving, with high cleaning efficiency and good cleaning effect. Moreover, the structure is compact and easy to operate, which is suitable for the mountainous pile foundation construction environment. During the cleaning process, the straight pipe section 11 of the slag outlet pipe 1 can form a support for the pile hole 10, thereby effectively preventing the pile hole 10 from collapsing and helping to ensure the quality of pile foundation construction.

[0031] In some embodiments, the slag outlet of the bend section 12 faces away from the handle-type press-type air valve 4. Thus, by setting the bend section 12 at the upper end of the straight section 11 and ensuring the slag outlet of the bend section 12 faces away from the handle-type press-type air valve 4, the discharged slag can be kept away from the operator and from the pile hole 10, preventing it from falling back down. The slag outlet of the bend section 12 is inclined upwards; specifically, in this embodiment, the slag outlet of the bend section 12 is arranged at a 30° angle to the horizontal plane. This ensures smooth slag discharge while keeping the slag away from the pile hole 10.

[0032] In some embodiments, the length of the straight pipe section 11 is not less than the depth of the pile hole 10. The air outlet pipe 5 is fixedly attached to the inner wall of the straight pipe section 11 on the side opposite to the slag outlet of the curved pipe section 12, so that the blown slag can be smoothly discharged from the slag outlet pipe 1. The position of the air outlet end of the air outlet pipe 5 is slightly higher than the position of the lower end of the straight pipe section 11; specifically, in this embodiment, the air outlet end of the air outlet pipe 5 is located at a position 50mm below the lower end of the straight pipe section 11. In this way, the high-pressure air blown out by the air outlet pipe 5 can effectively spray the slag at the bottom of the pile hole 10, thereby ensuring that the slag can be fully discharged from the slag outlet pipe 1, and the slag cleaning effect is good.

[0033] In some embodiments, the operating lever 3 is a hollow tubular structure with openings at both ends. Specifically, the operating lever 3 is made of a DN30 stainless steel tube 500mm long and 1mm thick. An opening is constructed in the middle of the operating lever 3, through which the air inlet end of the outlet duct 5 passes through the operating lever 3, and the air outlet end of the supply duct 6 passes through the operating lever 3. A handle-type press-button valve 4 is fixedly installed on the operating lever 3 and connected to the outlet duct 5 and the supply duct 6. Thus, by having the air inlet end of the outlet duct 5 and the air outlet end of the supply duct 6 pass through the operating lever 3, the outlet duct 5 and the supply duct 6 can be securely installed, preventing the pipes from tangling with the operating lever 3. Furthermore, it allows the operator to easily control the handle-type press-button valve 4 by holding the operating lever 3, making operation simple and convenient.

[0034] In some embodiments, rubber anti-slip sleeves are fitted at both ends of the operating lever 3 to improve the anti-slip properties of the operating lever 3.

[0035] In some embodiments, a duct coil 8 is also included, which is used to place and retract the air supply pipe 6. In this way, during the cleaning of multiple pile holes 10, the air supply pipe 6 can be retracted and retracted in a timely manner through the duct coil 8. On the one hand, this can effectively prevent the air supply pipe 6 from getting tangled in the construction area. On the other hand, it can effectively prevent the air supply pipe 6 from pushing the discharged scum back into the pile hole 10 during the dragging process.

[0036] In some embodiments, the high-pressure air source 7 is a mobile air compressor. Specifically, the mobile air compressor is a diesel-powered two-wheeled trailer-mounted air compressor with a displacement of 15-20 m³. 3 With a pressure of 10-14 bar per minute, it is suitable for mountainous construction environments, easy to move and transport, and convenient to operate, which helps to improve construction efficiency.

[0037] In some implementations, please refer to Figures 2-3 It also includes a duct connector 9, and an air supply pipe 6 including a fixed section 61 and a movable section 62; the fixed section 61 is connected to the high-pressure air source 7, and the movable section 62 is connected to the handle-type press-type air valve 4. The fixed section 61 and the movable section 62 are detachably connected through the duct connector 9. When it is necessary to clean pile holes 10 of different diameters, a slag discharge pipe 1 of the corresponding diameter is required. However, the slag discharge pipe 1 is fixedly connected to the air outlet pipe 5, which is not convenient for temporary disassembly and replacement. Furthermore, since the connection between the air inlet end of the air outlet pipe 5, the air outlet end of the air supply pipe 6, and the handle-type press-type air valve 4 is set on the operating lever 3, it is not convenient for temporary disassembly and replacement.

[0038] Therefore, in this embodiment, by dividing the air supply pipe 6 into a fixed section 61 and a movable section 62 connected by the air pipe joint 9, the slag discharge pipe 1, connecting rod 2, operating rod 3, handle-type press air valve 4, air outlet pipe 5, and the movable section 62 of the air supply pipe 6 can be formed into a cleaning module that can be disassembled and replaced as a whole. Thus, by using slag discharge pipes 1 of different specifications to pre-assemble a cleaning module that can adapt to different pile hole diameters 10, the cleaning needs of pile holes 10 of different diameters can be met. The cleaning module is easy to disassemble and replace, and the replacement efficiency is high, which is conducive to improving the efficiency of slag removal construction.

[0039] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
