DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0026] In remote mining areas, photovoltaic power generation can be used as a supplement or substitute for grid power to provide electricity for mining operations. As an indispensable component of solar photovoltaic power generation systems, photovoltaic brackets are mainly used to support, fix and adjust photovoltaic modules to ensure that the modules are at the best angle to receive sunlight, improve power generation efficiency, and maintain stability and safety under various environmental conditions. Cylindrical steel pipes or aluminum pipes of various diameters and wall thicknesses are commonly used in photovoltaic brackets because they have good strength and stability; photovoltaic bracket drilling is an important part of the construction of photovoltaic module bracket cast-in-place pile foundations. The position of the drilling hole needs to be accurately measured and located during drilling, and the drill rod needs to be kept vertical to the photovoltaic bracket during subsequent drilling. The verticality of the drilling is crucial to ensure the stability and safety of the photovoltaic bracket.

[0027] Existing photovoltaic bracket drilling tools generally include a mounting base, a gripping unit and a drilling unit. The gripping unit is arranged on one side of the mounting base. When drilling, the photovoltaic bracket is fixed and gripped by the gripping unit, and then drilling begins. The gripping unit of the existing photovoltaic bracket drilling tool includes a fixed half-frame connected to one end of the mounting base, and the photovoltaic bracket is gripped and fixed by a half-frame.

[0028] This method of grabbing and fixing the photovoltaic bracket through a half frame cannot ensure that the drill rod is completely perpendicular to the photovoltaic bracket when drilling. When drilling, it mainly relies on the human eye to ensure that the drill rod and the bracket remain perpendicular. This method results in low drilling accuracy.

[0029] The present invention discloses a photovoltaic support drilling tool, such as Figure 1-Figure 2As shown, it includes a mounting seat 1, two groups of gripping units and a vertical ruler 12; wherein the mounting seat 1 is a rectangular structure, and a mounting plate 11 horizontal to the mounting seat 1 is mounted on the surface of the mounting seat 1 through a plurality of first springs 10, and a drilling unit is arranged on the mounting plate 11; the two groups of gripping units are respectively arranged on one side of the mounting seat 1, and the two groups of gripping units are slidably connected to the mounting seat 1 and can slide in the direction of approaching and away from the drilling unit. When the two groups of gripping units slide in the direction of approaching each other, the photovoltaic bracket can be clamped and positioned, and each group of gripping units specifically includes a U-shaped frame 3, a positioning plate 5, and an adjustment plate 6. , joint 7, first adjustment nut 8 and second spring 9, U-shaped frame 3 is arranged on mounting plate 11, positioning plate 5 and adjustment plate 6 are semi-circular plates, the inner wall of positioning plate 5 and adjustment plate 6 has an arc-shaped cross section along the thickness direction, positioning plate 5 is fixed on the inner side of U-shaped frame 3, adjustment plate 6 is slidingly arranged on the lower side of positioning plate 5 and can slide in the direction close to positioning plate 5, joint 7 is arranged between positioning plate 5 and adjustment plate 6 through second spring 9, the outer side of joint 7 contacts the inner side of positioning plate 5 and adjustment plate 6 respectively, and first adjustment nut 8 is vertically arranged between positioning plate 5 and adjustment plate 6. The vertical end of vertical ruler 12 is fixedly connected to the lower side of joint 7, and the horizontal end of vertical ruler 12 is connected to mounting plate 11. After the photovoltaic bracket is clamped by two joints 7, mounting plate 11 can be adjusted to a horizontal state through vertical ruler 12 connected thereto, thereby ensuring that the drilling unit arranged on mounting plate 11 is vertical to the photovoltaic bracket.

[0030] In order to enable each group of gripping units to slide, sliding blocks 2 are respectively provided on both sides of the surface of the mounting seat 1 disclosed in this embodiment. The sliding blocks 2 are slidably connected to the mounting seat 1 and can slide in the direction of approaching and moving away from the drilling unit. The U-shaped frame 3 is arranged on the corresponding sliding block 2, and a sliding groove is provided on the surface of the mounting seat 1. The sliding block 2 can slide freely in the sliding groove.

[0031] When the photovoltaic bracket drilling tool disclosed in the present invention is in use, it first slides in a direction approaching each other through two groups of gripping units. When the two groups of gripping units approach each other, the joints 7 arranged thereon clamp the photovoltaic bracket respectively. When the two joints 7 contact the photovoltaic bracket, the first adjusting nut 8 is adjusted to make the distance between the two joints 7 infinitely shortened, and finally the two joints 7 clamp the bracket. After the two joints 7 clamp the bracket, the bottom surfaces of the two joints 7 are both in a vertical state with the photovoltaic bracket. At this time, the mounting plate 11 can be adjusted to a state horizontal with the bottom surfaces of the joints 7 through two vertical rulers 12. At this time, the mounting plate 11 is maintained in a position perpendicular to the bracket. In this way, the drill rod arranged on the mounting plate 11 can be in a vertical state with the bracket when drilling, thereby ensuring the final drilling accuracy.

[0032] Furthermore, the bottom surface of the positioning plate 5 disclosed in this embodiment is provided with a support plate 13 perpendicular thereto, one end of the second spring 9 is connected to the support plate 13, and the other end of the second spring 9 is connected to the joint 7. Therefore, the second spring 9 can keep the joint 7 in a state where it can slide freely, so when clamping, the joint 7 and the bracket can be clamped according to the actual situation of the photovoltaic bracket.

[0033] Furthermore, if Figure 3-Figure 4 As shown, the drilling unit disclosed in this embodiment includes a drill body 4 slidably arranged on a mounting plate 11, the drill body 4 can slide in a direction approaching and away from the gripping unit, and a mounting sleeve 15 and a drill rod 14 are sequentially arranged on the drill body 4, and a verticality adjustment component for adjusting the verticality of the drill rod 14 is arranged on the outer ring of the drill rod 14. The specific verticality adjustment component includes a fixing ring 16 that passes through the mounting sleeve 15 and is fixedly connected to the mounting sleeve 15. A first positioning ring 17 and a second positioning ring 18 are sequentially arranged on the side of the fixing ring 16 away from the mounting sleeve 15. The first positioning ring 17 and the second positioning ring 18 are both annular structures and are sleeved on the outside of the drill pipe 14. The inner rings of the first positioning ring 17 and the second positioning ring 18 have an arc-shaped cross-section in the thickness direction. A distance is left between the first positioning ring 17 and the second positioning ring 18 and the two are connected by a second adjusting nut 19. An adjusting block 20 is arranged between the inner sides of the first positioning ring 17 and the second positioning ring 18. The adjusting block 20 is annular and is located between the drill pipe 14, the first positioning ring 17 and the second positioning ring 18. The outer wall of the adjusting block 20 is also arc-shaped. The arc surface on the outer side of the adjusting block 20 contacts the arc surface on the inner side of the first positioning ring 17 and the second positioning ring 18 respectively, and the inner side of the adjusting block 20 contacts the drill pipe 14. Therefore, by rotating the second adjusting nut 19, the first positioning ring 17 and the second positioning ring 18 can be made to lean against each other, thereby squeezing the adjusting block 20 to adjust the verticality of the drill rod 14. Specifically, four second adjusting nuts 19 are arranged along the axial direction. If the drill rod 14 is observed to tilt to one side, the second adjusting nut 19 on the opposite side can be adjusted to achieve the purpose of adjusting the verticality of the drill rod 14.

[0034] Furthermore, the surface of the mounting plate 11 disclosed in the present embodiment is provided with a strip groove pointing to the gripping unit, a first screw rod 21 is provided inside the strip groove, a first slider 22 is also provided in the strip groove, the first slider 22 is threadedly connected to the first screw rod 21, and the lower side of the drilling rig body 4 is fixedly connected to the first slider 22; rotating the first screw rod 21 during the drilling process can control the drilling process.

[0035] Furthermore, a second screw 23 corresponding to the sliding block 2 is also provided inside the mounting seat 1, and two sections of threads with different rotation directions are provided on the second screw 23. Two second sliders 24 are slidably provided inside the upper sliding block 2, and the two second sliders 24 are respectively threadedly connected with the two sections of threads with different rotation directions. The lower end of the sliding block 2 passes through the upper surface of the mounting seat 1 and is respectively connected with a corresponding second slider 24. One end of the second screw 23 is rotatably connected with the inner wall of the mounting seat 1, and the other end of the second screw 23 passes through the side wall of the mounting seat 1 and is connected with a knob 25. Therefore, rotating the second screw 23 can clamp or loosen the photovoltaic bracket, so as to facilitate the control of the entire process.

[0036] Furthermore, in order to ensure the drilling accuracy of the photovoltaic bracket, a first pressure sensor is provided on the inner side of the adjustment block 20 disclosed in the present embodiment, and the first pressure sensor is connected to the control system. A second pressure sensor is provided on the inner side of the joint 7, and the second pressure sensor is connected to the control system. In addition, a display screen connected to the first pressure sensor and the second pressure sensor respectively is provided on the mounting base 1. Therefore, when the verticality of the drill rod 14 is adjusted by the adjustment block 20, or when the photovoltaic bracket is clamped by the two joints 7, the clamping process can be monitored by the first pressure sensor and then the second pressure sensor respectively, and the pressure value detected by the pressure sensor can be provided to the operator when it is transmitted to the display screen, so that the drill rod 14 and the joint 7 are kept in a suitable state during the clamping process to avoid the reduction of accuracy caused by excessive clamping force.

[0037] In summary, the present invention provides a photovoltaic bracket drilling tool. When drilling, two groups of gripping units are first slid in the direction of approaching each other. When the two groups of gripping units are close to each other, the joints 7 arranged thereon clamp the photovoltaic bracket respectively. When the two joints 7 are in contact with the photovoltaic bracket, the first adjusting nut 8 is adjusted to make the distance between the two joints 7 infinitely shortened and finally the two joints 7 clamp the bracket. After the two joints 7 clamp the bracket, the bottom surfaces of the two joints 7 are both in a vertical state with the photovoltaic bracket. At this time, the mounting plate 11 can be adjusted to a state horizontal with the bottom surfaces of the joints 7 through two vertical rulers 12. At this time, the mounting plate 11 is maintained at a position vertical to the bracket, so that the drill rod arranged on the mounting plate 11 can be in a state vertical to the bracket when drilling. Before drilling, the state of the drill rod 14 is adjusted by the second adjusting nut 19. After adjustment, the drill rod 14 can be ensured to be vertical to the photovoltaic bracket. Therefore, the present invention can ensure the final drilling accuracy.

[0038] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention belong to the protection scope of the present invention.
