Description

Technical Field

[0001] This utility model relates to the technical field of hole washing devices, specifically a hole washing device for photovoltaic support piles in mountainous areas with strong weathering. Background Technology

[0002] When installing photovoltaic brackets in highly weathered strata, drilling is required. After drilling is completed, hole washing is necessary, which involves cleaning mud, rock cuttings, and other sediment from the cracks in the borehole wall.

[0003] Existing hole washing devices use high-pressure water to flush the borehole wall during use. However, because the diameter of the drilled hole varies, the distance between the hole washing device and the borehole wall changes as the device moves up and down within the hole. When the hole washing device is too close to the borehole wall, the high-pressure water sprayed by the device can easily damage the borehole wall. Therefore, improvements are needed. To address this, those skilled in the art have proposed a hole washing device for photovoltaic support piles in mountainous areas with strong weathering to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a hole-washing device for photovoltaic support piles in mountainous areas with strong weathering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hole-washing device for photovoltaic support piles in strongly weathered mountainous strata includes a fixed block, a conveying pipe rotatably disposed within the fixed block, a turntable installed at one end of the conveying pipe extending out of the fixed block, several ring-shaped fixed plates installed at the bottom of the turntable, fixed rods mounted on the fixed plates, a movable frame slidably disposed on the fixed rods, a spray frame fixedly connected to the movable frame, and several spaced-apart nozzles installed on the spray frame, the spray frame being connected to the conveying pipe via a diversion pipe, and further comprising:

[0007] An adjustment mechanism, which is located inside the turntable, is used to adjust the position of the spray frame;

[0008] A cleaning mechanism, connected to an adjustment mechanism, is used to clean the borehole wall;

[0009] A drive mechanism is provided, which is located inside a fixed block, and is used to drive the conveying pipe to rotate.

[0010] As a further embodiment of this utility model: the adjustment mechanism includes several hydraulic rods arranged in a ring inside the turntable, the hydraulic rods being fixedly connected to a synchronization frame, and the synchronization frame being fixedly connected to a spray frame.

[0011] As a further embodiment of this utility model: the cleaning mechanism includes a rotating shaft rotatably disposed at the end of a hydraulic rod, the rotating shaft being rotatably connected to a connecting frame, the connecting frame being fixedly connected to a scraper, and the scraper being provided with springs connected to the hydraulic rod on both sides of the connecting frame.

[0012] As a further embodiment of this utility model: the driving mechanism includes a motor installed at the bottom of the inner wall of the fixed block, a second gear installed at the driving end of the motor, and a first gear meshing with the second gear installed on the conveying pipe.

[0013] As a further improvement of this utility model, a connector is provided on the fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model connects the connector to an external lifting mechanism and connects the delivery pipe to an external pipeline. The external pipeline delivers water needed to clean the borehole wall. During cleaning, the external lifting mechanism lowers the fixed block into the borehole, and the adjustment mechanism makes the cleaning mechanism contact the borehole wall. As the nozzles on the spray frame rotate and clean the borehole wall, the cleaning mechanism can remove the mud or rock debris washed off the borehole wall. In addition, the position of the spray frame is adjusted during the adjustment of the cleaning mechanism so that the distance between the spray frame and the borehole wall remains unchanged. Therefore, when cleaning at different diameter positions of the borehole wall, the distance between the nozzles on the spray frame and the borehole wall remains unchanged, thus avoiding the damage to the borehole wall caused by the high-pressure water sprayed from the nozzles being too close to the borehole wall.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Please see Figures 1-3 A hole-washing device for photovoltaic support piles in strongly weathered mountainous strata includes a fixed block 1, a connector 2 on the fixed block 1, a conveying pipe 3 rotatably disposed inside the fixed block 1, a turntable 7 installed at one end of the conveying pipe 3 extending out of the fixed block 1, several ring-shaped fixed plates 17 installed at the bottom of the turntable 7, a fixed rod 18 installed on the fixed plate 17, a movable frame 19 slidably disposed on the fixed rod 18, the movable frame 19 being fixedly connected to a spray frame 13, and several spaced nozzles 14 installed on the spray frame 13. The spray frame 13 is connected to the conveying pipe 3 through a diversion pipe 15, and water conveyed by the conveying pipe 3 enters the spray frame 13 through the diversion pipe 15 and then sprays out from the nozzles 14. The device also includes:

[0021] An adjustment mechanism is provided inside the turntable 7 for adjusting the position of the spray frame 13;

[0022] A cleaning mechanism, connected to an adjustment mechanism, is used to clean the borehole wall;

[0023] A drive mechanism is provided inside the fixed block 1 and is used to drive the conveying pipe 3 to rotate.

[0024] By connecting the connector 2 to the external lifting mechanism and connecting the delivery pipe 3 to the external pipeline, the external pipeline delivers the water needed to clean the borehole wall. During cleaning, the external lifting mechanism lowers the fixing block 1 into the borehole, and the adjustment mechanism makes the cleaning mechanism contact the borehole wall. As the nozzle 14 on the spray frame 13 rotates and cleans the borehole wall, the cleaning mechanism can remove the mud or rock debris washed off the borehole wall. In addition, the position of the spray frame 13 is adjusted during the adjustment of the cleaning mechanism so that the distance between the spray frame 13 and the borehole wall remains unchanged. Thus, when cleaning at different diameter positions of the borehole wall, the distance between the nozzle 14 on the spray frame 13 and the borehole wall remains unchanged, thereby avoiding the high-pressure water sprayed from the nozzle 14 being too close to the borehole wall and damaging the borehole wall.

[0025] In one embodiment, the adjustment mechanism includes a plurality of hydraulic rods 8 arranged in a ring within the turntable 7. The hydraulic rods 8 are fixedly connected to a synchronization frame 16, and the synchronization frame 16 is fixedly connected to a spray frame 13.

[0026] It should be noted that several hydraulic rods 8 are synchronized through a controller, so that multiple cleaning mechanisms can move synchronously and the fixing block 1 is located at the center of the drill hole.

[0027] In this embodiment, by activating several hydraulic rods 8 synchronously, multiple cleaning mechanisms can be driven to move and contact the borehole wall. At the same time, the moving frame 19 is driven to move along the fixed rod 18 via the synchronous frame 16, causing the spray frame 13 to move in position. This keeps the distance between the nozzles 14 on the spray frame 13 and the borehole wall unchanged, preventing the nozzles 14 from getting too close to the borehole wall and causing the high-pressure water sprayed out to damage the borehole wall.

[0028] In one embodiment, the cleaning mechanism includes a rotating shaft 9 rotatably disposed at the end of the hydraulic rod 8, the rotating shaft 9 being rotatably connected to a connecting frame 10, the connecting frame 10 being fixedly connected to a scraper 11, and the scraper 11 being provided with springs 12 connected to the hydraulic rod 8 on both sides of the connecting frame 10.

[0029] Under the action of the adjustment mechanism, the scraper 11 will contact the borehole wall. Thus, as the drive mechanism drives the conveying pipe 3 to rotate the turntable 7, the scraper 11 will clean the mud and rock cuttings on the borehole wall. Furthermore, due to the elastic tension of the spring 12, the scraper 11 can rotate around the rotating shaft 9. Therefore, even when the diameter of the borehole changes, the scraper 11 can still contact the borehole wall, resulting in better performance.

[0030] In one embodiment, the driving mechanism includes a motor 6 installed at the bottom of the inner wall of the fixed block 1, a second gear 5 installed at the driving end of the motor 6, and a first gear 4 that meshes with the second gear 5 installed on the conveying pipe 3.

[0031] When in use, the motor 6 is started by the external controller. The first gear 4 and the second gear 5 are meshed, which drive the conveying pipe 3 to rotate, thereby driving the turntable 7 to rotate. This causes the nozzles 14 on the spray frame 13 to also rotate, so that the borehole wall can be rotated and rinsed.

[0032] The working principle of this utility model is as follows: By connecting the connector 2 to the external lifting mechanism and connecting the conveying pipe 3 to the external pipeline, the external pipeline delivers the water required for cleaning the borehole wall to the conveying pipe 3. During cleaning, the fixed block 1 is lowered into the borehole through the external lifting mechanism, and the cleaning mechanism is adjusted to contact the borehole wall. Thus, during the process of the nozzle 14 on the spray frame 13 rotating and cleaning the borehole wall, the cleaning mechanism can clean the mud or rock debris washed off the borehole wall. In addition, the position of the spray frame 13 is also adjusted during the adjustment of the cleaning mechanism so that the distance between the spray frame 13 and the borehole wall remains unchanged. Thus, when cleaning at different diameter positions of the borehole wall, the distance between the nozzle 14 on the spray frame 13 and the borehole wall remains unchanged, thereby avoiding the high-pressure water sprayed from the nozzle 14 being too close to the borehole wall and damaging the borehole wall.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
