However, this type of structural design makes it difficult to flexibly adjust the drilling angle and orientation, resulting in a single adjustment dimension and insufficient flexibility. This makes it difficult to accurately locate the drilling position when constructing in complex terrain, which not only affects the accuracy of pre-drilling but also significantly reduces construction efficiency.

[0042] This invention provides a technical solution: a hole-drilling device for the construction of photovoltaic module support foundations. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 ,include:

A detection component 29 is provided on the outside of the hollow plate 21.

[0045] Activating the electric telescopic rod 22 can push the lifting plate 23 to move along the hollow plate 21, thereby driving the motor 24 to move synchronously. After starting the motor 24, it can drive the drill rod 25 to rotate to realize the pilot hole operation. At the same time, the height and depth of the pilot hole can be adjusted. Activating the first motor 26 can drive the entire hollow plate 21 to rotate, thereby realizing the adjustment of the pilot hole angle. In addition, pushing the rotating cover 5 to rotate along the base plate 1 can further adjust the orientation of the pilot hole of the device.

[0046] Please see Figure 2 , Figure 5 and Figure 7 The replacement mechanism 3 includes a hollow cover 31, which is rotatably connected to the bottom of the lifting plate 23. The top of the drill rod 25 is provided with slots 35 on both the left and right sides. The top of the hollow cover 31 is fixedly connected to the output end of the motor 24. The bottom of the outer side of the hollow cover 31 is rotatably connected to a first rotating ring 32. The inner left and right sides of the first rotating ring 32 are rotatably connected to spring telescopic blocks 33. The rotation of the first rotating ring 32 can push the spring telescopic blocks 33 to move. The outer side of the spring telescopic blocks 33 is rotatably connected to a locking block 34.

The outer side of the hollow cover 31 is provided with a positioning component 36, and the outer side of the base plate 1 is provided with a transport component 37.

[0047] After inserting the top of the drill rod 25 into the hollow cover 31, push the first rotating ring 32 to rotate along the hollow cover 31. The spring telescopic block 33 on the first rotating ring 32 will rotate accordingly. Its telescopic and rotating action can push the locking block 34 to move along the inside of the hollow cover 31, so that the locking block 34 extends out of the hollow cover 31 and engages with the locking groove 35 on the drill rod 25, thereby realizing the quick disassembly and replacement of the drill rod 25.

[0048] Please see Figure 1 , Figure 4 and Figure 8The cleaning mechanism 4 includes a water tank 41. Two water tanks 41 are fixedly connected to the top left and right sides of the rotating cover 5 respectively. A water pump 42 is connected to the bottom of the water tank 41. The output end of the water pump 42 passes through the rotating cover 5 and is connected to a nozzle 43. A second rotating ring 44 is rotatably connected to the inner side of the base plate 1. A brush 45 is fixedly connected inside the second rotating ring 44. When the second rotating ring 44 rotates, it will drive the brush 45 to rotate, thereby cleaning the impurities generated during the drilling. Waste discharge grooves 46 are opened on the front and rear sides of the interior of the base plate 1 and the second rotating ring 44. When multiple waste discharge grooves 46 intersect, they can discharge impurities outside the base plate 1. Multiple push plates 47 are fixedly connected to the top of the second rotating ring 44. A protective component 49 is provided on the top of the water tank 41.

[0049] When the device performs the pilot hole operation, the water pump 42 is started to draw water from the water tank 41 into the nozzle 43. The water jets from the nozzles 43, which are placed diagonally on both sides, first spray onto the surface of the push plate 47. With the help of the thrust, the second rotating ring 44 rotates. During the rotation of the second rotating ring 44, the brush 45 on it works in conjunction with the spray water to clean the impurities generated by the pilot hole. At the same time, as the second rotating ring 44 rotates along the base plate 1, when the waste discharge tank 46 on it intersects, the sewage and impurities can be discharged outside the device.

[0050] Please see Figure 1 , Figure 3 and Figure 6 The angle adjustment assembly 27 includes a second motor 271, which is fixedly connected to the inside left side of the rotating cover 5. The output end of the second motor 271 passes through the rotating cover 5 and is fixedly connected to a bevel gear 272. Starting the second motor 271 can drive the bevel gear 272 to rotate. A bevel gear ring 273 is fixedly connected to the top of the outer side of the base plate 1. The bevel gear 272 and the bevel gear ring 273 are meshed and connected.

[0051] Mounting assembly 28 includes positioning blocks 281. Multiple positioning blocks 281 are fixedly connected to the outer periphery of the base plate 1. Positioning holes 282 are provided on the outer side of the positioning blocks 281. By inserting threaded parts into the positioning holes 282, the device can be easily fixed.

[0052] The detection component 29 includes a pointer 291, which is rotatably connected to the upper right wall of the hollow plate 21. An indicator plate 292 is fixedly connected to the middle right side of the hollow plate 21. When the device is tilted, the current aperture angle of the device can be determined by observing the indicator plate 292 indicated by the pointer 291.

[0053] By starting the second motor 271, the bevel gear 272 can be driven to rotate. At this time, through meshing with the bevel gear ring 273, the rotating cover 5 can be driven to rotate along the base plate 1 and the bevel gear ring 273. By inserting a threaded part into the positioning hole 282 on the positioning block 281, the device can be easily installed and fixed. When the hollow plate 21 rotates, due to the weight, the pointer 291 will rotate along the hollow plate 21 and remain horizontal with the ground. At this time, by observing the reading of the position of the indicator plate 292 indicated by the pointer 291, the tilt and hole angle of the current device can be determined.

[0054] Please see Figure 2 , Figure 7 and Figure 8 The positioning component 36 includes a positioning ring 361, which is slidably connected to the upper outer side of the hollow cover 31. The top of the first rotating ring 32 is provided with multiple positioning grooves 362. The positioning ring 361 engages with the positioning grooves 362, and the engagement of the positioning ring 361 with the positioning grooves 362 can position the first rotating ring 32.

[0055] The handling assembly 37 includes hollow blocks 371, and multiple hollow blocks 371 are fixedly connected to the top periphery of the base plate 1. A handle 372 is rotatably connected to the inner side of the hollow block 371, and the device can be easily handled and stored by holding the handle 372.

[0056] By moving the positioning ring 361 to engage with the corresponding positioning groove 362, the position of the first rotating ring 32 can be limited so as to keep the locking block 34 engaged with the locking groove 35. By holding the handle 372 that can rotate along the hollow block 371, it is easy to move and operate the device.

[0057] Please see Figure 3 , Figure 4 and Figure 8 The protective component 49 includes two movable doors 491, which are respectively installed on the top of the water tank 41. Hinges 492 are fixedly connected to the front and rear sides of the movable doors 491. The movable doors 491 are rotatably connected to the water tank 41 through the hinges 492. The movable doors 491 can be opened and closed through the hinges 492. When closed, they can protect the water tank 41. When opened and closed, they can facilitate the replenishment of water into the water tank 41.

[0058] The cleaning mechanism 4 also includes a connecting ring 48, which is fixedly connected to the middle of the outer side of the second rotating ring 44. The connecting ring 48 is rotatably connected to the base plate 1, and the connecting ring 48 can improve the stability of the rotation of the second rotating ring 44.

[0059] The hinge 492 allows the movable door 491 to be opened and closed to replenish water to the water tank 41, while preventing impurities from entering the water tank 41 when closed. The rotation of the connecting ring 48 and the base plate 1 can improve the stability of the second rotating ring 44 during rotation.

[0060] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 A protective pad is fixedly connected to the bottom of the base plate 1. Multiple protective pads are evenly distributed around the bottom of the base plate 1, and the protective pads cover the area between the positioning blocks 281 at the bottom of the base plate 1. A wear-resistant pad is fixedly connected to the inner side of the slide groove 210 of the hollow plate 21. The wear-resistant pad is set to fit the inner wall of the slide groove 210, and the wear-resistant pad is slidably connected to the outer side of the lifting plate 23.

[0061] The protective pad protects the base plate 1, prevents slipping and reduces wear, and extends the service life of the equipment; the wear-resistant pad reduces friction loss between the lifting plate 23 and the slide 210, ensuring smooth sliding; both the protective pad and the wear-resistant pad are made of wear-resistant polyurethane, which has good toughness and wear resistance, and is suitable for complex construction conditions.

[0062] This solution: By activating the electric telescopic rod 22, it can push the lifting plate 23 to move along the hollow plate 21. At this time, it can drive the motor 24 to move accordingly. After activating the motor 24, it can drive the drill rod 25 to rotate to drill a hole and adjust the height or depth of the hole. Then, the first motor 26 is activated to drive the entire hollow plate 21 to rotate, which can adjust the angle of the hole. At the same time, by pushing the rotating cover 5 to rotate along the base plate 1, the orientation of the hole can be further adjusted.

[0063] Furthermore, by inserting the top of the drill rod 25 into the hollow cover 31, and then pushing the first rotating ring 32 to rotate along the hollow cover 31, the spring telescopic block 33 on the first rotating ring 32 will also rotate with it. The extension and rotation of the spring telescopic block 33 will push the locking block 34 to move. The locking block 34 will move along the inside of the hollow cover 31, so that it extends out of the hollow cover 31 and engages with the locking groove 35 on the drill rod 25. This allows for quick disassembly and replacement of the drill rod 25.

[0064] Finally, during the pre-hole drilling process, the water pump 42 is activated to draw water from the water tank 41 into the nozzle 43. As the nozzles 43, which are placed diagonally on both sides, spray water, the water will first spray onto the surface of the push plate 47, causing it to rotate the second rotating ring 44 through thrust. At this time, as the second rotating ring 44 rotates, the brush 45 on it and the sprayed water can clean the impurities drilled during the pre-hole drilling process. As the second rotating ring 44 rotates along the base plate 1, the waste discharge trough 46 on it intersects with it, discharging the sewage and impurities out of the device.
