Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket installation technology, specifically a special device for fastening ground bolts of photovoltaic brackets. Background Technology

[0002] In photovoltaic (PV) power generation systems, the stability of the support structure is crucial for the safe operation of PV modules. Currently, PV supports are primarily fixed to the ground or counterweights using anchor bolts to ensure their resistance to wind loads and overturning. However, traditional bolt-fastening methods suffer from significant efficiency bottlenecks and insufficient adaptability.

[0003] First, the installation and removal of the fixing bolts on both sides of the bracket are time-consuming and labor-intensive, especially in the installation and maintenance of large-scale photovoltaic power plants, where this sequential operation mode severely restricts construction efficiency. Second, the bolt hole spacing tolerances of different specifications of bracket pads exist in practical applications, and traditional fastening tools lack effective spacing adjustment mechanisms, resulting in poor tool-bolt compatibility. This not only affects construction quality but may also damage the bolts or tools due to forced installation.

[0004] A special device for fastening ground bolts of photovoltaic brackets is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a dedicated device for fastening ground bolts of photovoltaic brackets, addressing the issues raised in the background art where the fixing bolts on both sides of the bracket need to be disassembled and assembled one by one, resulting in a time-consuming and labor-intensive process. This sequential operation mode severely restricts construction efficiency, especially in the installation and maintenance of large-scale photovoltaic power plants. Secondly, the bolt hole spacing tolerances of different specifications of bracket pads in practical applications, coupled with the lack of effective spacing adjustment mechanisms in traditional fastening tools, lead to poor tool-bolt compatibility. This not only affects construction quality but may also cause damage to bolts or tools due to forced installation.

The fastening assembly includes a mounting shell with a groove on one side. A layered plate is fixedly connected inside the mounting shell. Adjustment grooves are symmetrically provided on both sides of the layered plate. A cylinder is provided inside the adjustment groove. A driven sprocket is fixedly connected to the top of the cylinder. A slot block is fixedly connected to the bottom of the cylinder.

A movable block is slidably connected to the middle of the layered plate. A second adjusting bolt is rotatably connected to one side of the movable block. A miniature tensioning sprocket is rotatably connected to the top of the movable block. A first motor is fixedly connected to one side of the bottom of the layered plate. The driven sprocket, spur sprocket, and miniature tensioning sprocket are externally meshed with the same chain. The bottom of the mounting shell has symmetrically opened clearance openings.

[0007] Preferably, the first adjusting stud is threaded to the side of the mounting housing, the bit is magnetically engaged with the slot block, the bit is snapped into the fixing bolt, and a collar is rotatably connected to the outside of the cylinder, the collar being slidably connected to the adjusting groove.

[0008] Preferably, the output end of the first motor passes through the layered plate and is fixedly connected to a separate steering sprocket.

[0009] Preferably, the second adjusting bolt is threadedly slidably connected to one side of the mounting housing, and the clearance opening is located directly below the bit.

[0010] Preferably, a guide mechanism is symmetrically provided on the top surface of the mounting shell. The guide mechanism includes a fixed shell fixed to the top surface of the mounting shell, a mounting sleeve fixedly connected inside the fixed shell, a movable rod slidably connected to one side of the mounting sleeve, and a first spring fixedly connected inside the mounting sleeve.

[0012] Preferably, the support column is fitted into the groove.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This special device for fastening ground bolts of photovoltaic brackets, through an innovative sprocket synchronous transmission system and spacing adjustment mechanism, achieves efficient synchronous disassembly and assembly of double bolts, adaptive hole spacing, and dynamic chain tensioning. It is also equipped with a modular quick-change bit system, significantly improving operational efficiency and equipment versatility. Its specific details are as follows: 1. The system employs an integrated layered plate cylinder and chain cylinder transmission structure within the mounting housing cylinder. This allows the first motor cylinder to synchronously drive the driven sprocket cylinders on both sides via the steering sprocket cylinder. Torque is then precisely transmitted to the bit cylinder via the cylinder and slot block cylinder, enabling simultaneous disassembly and assembly of the two fixing bolt cylinders. Compared to disassembly using a single electric wrench, this significantly improves disassembly efficiency. Secondly, the first adjusting screw cylinder drives the control ring cylinder, allowing the cylinder to move linearly within the adjusting slot cylinder. This accommodates pad cylinders with different hole spacing specifications. Simultaneously, the second adjusting screw cylinder drives the dynamic tensioning design of the micro-tensioning sprocket cylinder, ensuring the chain cylinder maintains optimal meshing under various working conditions. Finally, the modular bit cylinder quick-change system allows for rapid replacement of different bit sizes via the clearance cylinder. Combined with a magnetic docking structure, tool changeover time is controlled within 5 seconds, greatly enhancing the equipment's versatility.

[0014] 2. The mounting sleeve cylinder inside the fixed shell cylinder and the first spring cylinder form an adaptive pushing mechanism. When the support column cylinder is inserted into the groove cylinder, the spring force pushes the mounting block cylinder through the movable rod cylinder, so that the guide ball cylinder always rolls against the outer wall of the support column, which assists in manual positioning and reduces the time spent on manual alignment.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-7 This utility model provides a technical solution: a special device for fastening ground bolts of photovoltaic brackets, including a fastening component 2, a bracket support 1 in the middle of the fastening component 2, a pad 101 fixedly connected to the bottom of the bracket support 1, a counterweight 103 attached to the bottom surface of the pad 101, and fixing bolts 102 symmetrically installed on both sides of the pad 101, the fixing bolts 102 being threadedly connected to the counterweight 103; during operation, the counterweight 103 enhances the stability of the pad 101 through gravity, and the fixing bolts 102 are screwed into the counterweight 103 to anchor the bracket support 1.

[0019] The fastening assembly 2 includes a mounting shell 201. A groove 202 is provided on one side of the mounting shell 201. A layered plate 203 is fixedly connected inside the mounting shell 201. Adjustment grooves 204 are symmetrically provided on both sides of the layered plate 203. A cylinder 205 is provided inside the adjustment groove 204. A driven sprocket 206 is fixedly connected to the top of the cylinder 205. A slot block 207 is fixedly connected to the bottom of the cylinder 205. A control ring 208 is rotatably connected to the outside of the slot block 207. A first adjusting stud 209 is rotatably connected to one side of the control ring 208. A screwdriver bit 210 is inserted into the bottom of the slot block 207. By rotating the first adjusting stud 209, the control ring 208 is driven, causing the cylinder 205 to slide along the adjustment groove 204, thereby adjusting the spacing of the screwdriver bits 210 on both sides to accommodate fixing bolts 102 with different hole spacings.

[0020] Two pairs of steering sprockets 211 are symmetrically and rotatably mounted on both sides of the layered plate 203. A movable block 212 is slidably connected to the middle of the layered plate 203. A second adjusting bolt 213 is rotatably connected to one side of the movable block 212. A miniature tensioning sprocket 214 is rotatably connected to the top of the movable block 212. A first motor 215 is fixedly connected to one side of the bottom of the layered plate 203. The driven sprocket 206, steering sprocket 211 and miniature tensioning sprocket 214 are externally meshed with the same chain 216. The bottom of the mounting shell 201 is symmetrically provided with clearance openings 217. The first motor 215 synchronously drives the driven sprockets 206 on both sides through the chain 216, driving the bit 210 to rotate to achieve synchronous disassembly and assembly of the two bolts. The second adjusting bolt 213 pushes the movable block 212 to move, so that the miniature tensioning sprocket 214 dynamically tensions the chain 216 to ensure transmission stability.

[0021] The first adjusting stud 209 is threaded to the side of the mounting housing 201. The bit 210 is magnetically engaged with the slot block 207. The bit 210 is snapped into the fixing bolt 102. The cylinder 205 is externally rotatably connected with a collar, which is slidably connected to the adjusting groove 204. The magnetic bit 210 is easy to replace quickly. The sliding fit between the collar and the adjusting groove 204 ensures that the cylinder 205 rotates smoothly during the adjustment process.

[0022] The output end of the first motor 215 passes through the layered plate 203 and is fixedly connected to an independent steering sprocket 211; the motor power is transmitted to the chain 216 through the steering sprocket 211, forming a closed-loop transmission system.

[0023] The second adjusting bolt 213 is threadedly slidably connected to one side of the mounting housing 201, and the clearance opening 217 is located directly below the bit 210; the clearance opening 217 provides operating space for the bit 210, and the threaded sliding of the second adjusting bolt 213 achieves precise tensioning of the chain 216.

[0024] A guide mechanism 3 is symmetrically provided on the top surface of the mounting shell 201. The guide mechanism 3 includes a fixed shell 301 fixed to the top surface of the mounting shell 201. A mounting sleeve 302 is fixedly connected inside the fixed shell 301. A movable rod 303 is slidably connected to one side of the mounting sleeve 302. A first spring 306 is fixedly connected inside the mounting sleeve 302. The guide mechanism 3 pushes the movable rod 303 by the elastic force of the first spring 306, so that the guide ball 305 always fits against the support column 1, and the auxiliary device is installed in position.

[0025] One end of the movable rod 303 extends into the mounting sleeve 302 and is fixedly connected to the first spring 306. The other end of the movable rod 303 is fixedly connected to the mounting block 304. The outer side of the mounting block 304 is rotatably connected to the guide ball 305. The mounting block 304 and the fixed shell 301 are slidably connected through it. The rolling of the guide ball 305 reduces friction and ensures that the device moves smoothly along the support column 1.

[0026] The support column 1 is fitted into the groove 202; the fitting structure between the groove 202 and the support column 1 enables rapid positioning and improves installation accuracy.

[0027] Working principle: Before using this special device for fastening ground bolts of photovoltaic brackets, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 7 As shown, in use, the mounting shell 201 is first inserted into the bottom of the support column 1 through the groove 202. Then, the mounting shell 201 is lowered so that the fixing bolt 102 can be inserted into the mounting shell 201 through the relief hole 217 and mate with the bit 210. Then, the first motor 215 is started so that the steering sprocket 211 drives the driven sprockets 206 on both sides to rotate through the chain 216. The driven sprockets 206 drive the cylinder 205 to rotate, and the bit 210 is driven to rotate through the slot block 207, thereby causing the fixing bolt 102 to rotate, realizing the quick disassembly of the two fixing bolts 102. During the disassembly process, the mounting shell 201 is held and moves upward as the fixing bolt 102 is removed from the pad 101. This device can simultaneously disassemble and assemble the two bolts on the pad 101, avoiding the traditional situation of installing them one by one with an electric wrench, greatly increasing the installation efficiency. When the position of the hole on the standard pad 101 changes due to design reasons, by rotating the first adjusting studs 209 on both sides, the control ring 208 drives the cylinder 205 to move horizontally in the adjusting groove 204, thereby enabling the position of the bit 210 to be finely adjusted, and thus enabling the device to make adaptive adjustments to pads 101 of different specifications. During the adjustment of the driven sprocket 206, the position of the movable block 212 driven by the second adjusting bolt 213 can be changed by rotating the second adjusting bolt 213, thereby allowing the micro tension sprocket 214 to keep the chain 216 taut after adjustment. Depending on the size and style of the fixing bolt 102, the bit 210 can be quickly replaced through the clearance 217; When the support column 1 is inserted into the groove 202, the first spring 306 can push the movable rod 303 to make the guide ball 305 move against the outside of the support column 1. When held by a person and without bias force, it assists the support column 1 to move to the middle of the groove 202, which finally facilitates the insertion of the fixing bolt 102 into the mounting shell 201.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
