Description

Technical Field

[0001] This invention relates to the field of photovoltaic grounding wire fixing technology, and in particular to a photovoltaic module grounding wire installation device. Background Technology

[0002] To avoid potential safety hazards, photovoltaic panels are grounded during installation. The various photovoltaic supports are connected by grounding wires. Currently, most installations use bolts and nuts to fix both ends of the grounding wire to adjacent photovoltaic supports, using the photovoltaic supports as conductors to ground all photovoltaic panels. To improve the installation efficiency of the grounding wire, a photovoltaic module grounding wire installation device is proposed.

[0003] In existing technologies, the typical process for fixing bolts and nuts is as follows: first, the bolt is passed through the loop at the end of the grounding wire, and then the bolt is passed through the reserved hole on the photovoltaic bracket. During this process, the nut is prone to falling off, affecting installation efficiency. In addition, during the installation process, the nut needs to be kept in place while the bolt is rotating, and the bolt needs to be kept in place while the nut is rotating. Therefore, it is essential to provide restraints during the installation process. Usually, construction workers hold the nut directly, which also increases the risk of injury to the construction workers. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] The following is combined with Figures 1 to 5 As shown, an embodiment of the present invention provides a photovoltaic module grounding wire installation device, comprising:

[0052] Two housings 8 are arranged vertically. One housing 8 has a first fixing component at one end, and the other housing 8 has a second fixing component at one end. The first fixing component is used to fix the bolt, and the second fixing component is used to fix the nut.

[0053] Two transmission components are respectively installed in two housings 8, and the two transmission components are used to drive the first fixed component and the second fixed component to rotate.

[0054] Box 1, a power assembly is installed inside the box 1, and the power assembly is connected to two transmission assemblies;

[0055] Two support components are provided on the two side walls of the housing 1 and are connected to the two shells 8. The support components are used to ensure that the two shells 8 always remain parallel.

[0056] Spring 7 is fixed between the two housings 8.

[0057] The bolts and nuts are magnetically secured by the first and second fixing components, respectively. The positioning of the housing 8 ensures that the bolts and nuts will not fall off during installation and can be handled without manual intervention, thereby improving the installation efficiency of the grounding wire. The support component ensures that the two housings 8 remain parallel during movement, thus guaranteeing the installation of the bolts and nuts. In addition, the power component and transmission component enable the bolts and nuts to rotate synchronously and in opposite directions, achieving rapid installation and fixation of the bolts and nuts.

[0058] Specifically, the first fixed component includes:

[0059] The first base 15 is rotatably disposed within one of the housings 8;

[0060] The fixing groove 22 is formed at the bottom of the first base 15, and the fixing groove 22 is adapted to the screw head of the bolt;

[0061] The first magnet 23 is fixed on the inner wall of the top of the fixing groove 22, and the first magnet 23 uses magnetic attraction to fix the screw head of the fixing bolt.

[0062] Specifically, the second fixing component includes:

[0063] The second seat 21 is rotatably disposed within another housing 8;

[0064] A through hole 26 is provided, which extends through the top of the second base 21 and is adapted to a bolt.

[0065] Multiple support plates 24 are fixed on multiple inner walls of the through hole 26, and a second magnet 25 is fixed on the top of each support plate 24.

[0066] The bolt head is placed in the fixing groove 22, and the bolt is fixed to the first base 15 by the action of the first magnet 23. The nut is placed in the through hole 26 of the second base 21, and the nut is fixed to the second base 21 by the support of the support plate 24 and the magnetic attraction of the second magnet 25.

[0067] Specifically, the transmission components include:

[0068] The first transmission wheel 16 and the second transmission wheel 20 are both disposed inside the housing 8;

[0069] A transmission belt 18 is fitted onto the first transmission wheel 16 and the second transmission wheel 20.

[0070] Turntable 19 is rotatably disposed inside housing 8, and second transmission wheel 20 is fixedly sleeved on turntable 19.

[0071] Specifically, one of the first transmission wheels 16 is fixedly sleeved on the first base 15, and the other first transmission wheel 16 is fixedly sleeved on the second base 21.

[0072] Specifically, the power components include:

[0073] Two gears 14 are rotatably mounted on the inner wall of the box 1, and the two gears 14 mesh with each other;

[0074] Motor 13 is fixed to the inner wall of the box 1, and the output shaft of motor 13 is fixed to one of the gears 14;

[0075] Two transmission units are fixed to two gears 14 respectively, and two transmission units are fixed to two turntables 19 respectively.

[0076] When the motor 13 is working, it drives the gear 14 to rotate. When the gear 14 rotates, it drives the two turntables 19 to rotate through the first universal joint 9, sleeve 11, two prisms 10 and the second universal joint 12. During this process, since the two gears 14 are meshed, the two gears 14 rotate in opposite directions, which in turn makes the two turntables 19 rotate in opposite directions. Through the first transmission wheel 16, transmission belt 18 and the second transmission wheel 20, the first seat 15 and the second seat 21 drive the bolts and nuts to rotate in opposite directions.

[0077] Specifically, the transmission unit includes:

[0078] The first universal joint 9 is fixed to the gear 14;

[0079] The second universal joint 12 is fixed to the turntable 19;

[0080] Sleeve 11, with two prisms 10 slidably disposed inside sleeve 11, and the two prisms 10 being fixed to the first universal joint 9 and the second universal joint 12 respectively.

[0081] By utilizing the sliding between the prism 10 and the sleeve 11, as well as the action of the first universal joint 9 and the second universal joint 12, the two housings 8 can still ensure power transmission when they approach or move away from each other.

[0082] Specifically, the supporting components include:

[0083] Shaft 2 is fixed to the side wall of box 1;

[0084] Two connecting rods 3 are rotatably connected to shaft 2, and the two shafts 2 are in an "X" shape. Each connecting rod 3 has a connecting component at both ends, and the connecting components at both ends of each connecting rod 3 are respectively connected to the two housings 8.

[0085] Specifically, the connection components include:

[0086] Two support plates 4 are fixed to the housing 8;

[0087] Guide rod 5, guide rod 5 is fixed between two support plates 4;

[0088] Connecting shaft 6 is slidably connected to guide rod 5, and the ends of connecting shaft 6 and connecting rod 3 are rotatably connected.

[0089] As the two housings 8 approach each other, the sliding between the connecting shaft 6 and the guide rod 5, as well as the rotation of the connecting rod 3 and the shaft 2, ensure that the two housings 8 remain parallel to each other throughout the process.

[0090] Specifically, each housing 8 has a carbon brush 17 fixed inside, and the two carbon brushes 17 respectively abut against the first seat 15 and the second seat 21.

[0091] When the two housings 8 approach each other, they cause the bolt to approach the nut. When the bolt and nut collide, the small circuit is connected through the first seat 15, the second seat 21 and the carbon brush 17. At this time, the current generated by the connection of the above circuit is recognized by the automatic control system. Subsequently, the automatic control system turns on the switch of the motor 13 to improve the automation level of the device and improve the installation efficiency.

[0092] In practical use, the bolt head is placed in the fixing groove 22, and the bolt is fixed to the first base 15 by the action of the first magnet 23. The nut is placed in the through hole 26 of the second base 21, and the nut is fixed to the second base 21 by the support of the support plate 24 and the magnetic attraction of the second magnet 25.

[0093] The metal ring of the grounding wire is passed through the bolt, and then the bolt is passed through the reserved hole on the photovoltaic bracket. Then the worker can hold the two housings 8 and bring the two housings 8 close to each other. During this process, the spring 7 is compressed.

[0094] By sliding between the connecting shaft 6 and the guide rod 5, and by rotating the connecting rod 3 and the shaft 2, the two housings 8 remain parallel as they approach each other.

[0095] When the two housings 8 approach each other, they cause the bolt to approach the nut. When the bolt and nut come into contact, the small circuit is connected through the first seat 15, the second seat 21 and the carbon brush 17. At this time, the current generated by the connection of the above circuit is recognized by the automatic control system. Subsequently, the automatic control system turns on the switch of the motor 13. The automatic control system is existing technology and will not be described in detail here.

[0096] It is worth noting that in the above small loops, such as Figure 6 As shown, the system includes a battery, a resistor, and a current sensor. The principle is as follows: two carbon brushes 17, the battery, the resistor, and the current sensor are connected in series. When the bolt and nut are in contact, it is equivalent to a series circuit, where the two carbon brushes 17 are connected (through the first seat 15, the second seat 21, the bolt, and the nut). After connection, the circuit generates current, which is then used by the current sensor to generate a signal. When the automated control system receives this signal, it switches on the motor 13. The significance of this circuit is that when the tool is completely placed outside the bolt and nut, the circuit is connected, and the motor 13 can be started. Additionally, this application also includes a battery and a controller, which is used to control the entire automation process.

[0097] In the initial state of the device, the two housings are separated, the bolt and nut are not yet in contact, and the circuit between the two carbon brushes is open, with no current flowing in the circuit. When the two housings approach each other and the bolt and nut come into contact, current flows from carbon brush 17 through the first seat 15, the bolt, the nut, the second seat 21, and back to the other carbon brush 17, completing the circuit. The current sensor then detects the current signal and transmits it to the automatic control system, which triggers a relay to connect the working circuit of motor 13, driving the device to begin tightening the nut.

[0098] The significance of the carbon brush 17 design lies in the fact that it uses the physical contact between the bolt and nut as the trigger condition, ensuring that the motor will only start automatically after the device is fully in place and the tool is accurately fitted onto the bolt and nut. This fundamentally avoids idling or operational errors caused by premature rotation, and significantly improves the automation level and operational safety of the device.

[0099] Two transmission units are fixed to two gears 14 respectively, and two transmission units are fixed to two turntables 19 respectively.

[0100] When motor 13 is working, it drives gear 14 to rotate. When gear 14 rotates, it drives two turntables 19 to rotate through the first universal joint 9, sleeve 11, two prisms 10, and second universal joint 12. During this process, because the two gears 14 are meshed, their rotation directions are opposite, which in turn causes the two turntables 19 to rotate in opposite directions. Through the first transmission wheel 16, transmission belt 18, and second transmission wheel 20, the first seat 15 and the second seat 21 drive the bolt and nut to rotate in opposite directions. During this process, because the two gears 14 are meshed, their rotation directions are opposite, which in turn causes the two turntables 19 to rotate in opposite directions. At the same time, by utilizing the sliding between prism 10 and sleeve 11, as well as the action of the first universal joint 9 and the second universal joint 12, power transmission can still be guaranteed when the two housings 8 are approaching or moving away from each other.

[0101] The overall function of the transmission unit is to transmit the rotational power of the motor 13 located in the central housing 1 through a series of intermediate transmission structures to the turntable 19 located in the movable housings 8 on both sides, thereby driving the first seat 15 and the second seat 21 to rotate the bolts and nuts to complete the fastening action.

[0102] The specific transmission path is as follows: The output shaft of motor 13 drives two meshing gears 14 to rotate. Since the two gears mesh directly, their rotation directions are opposite. This design is the fundamental source of the relative reversal between the upper and lower sides. Each gear 14 is connected to a transmission chain. Power is transmitted from gear 14 through the first universal joint 9, the prism 10 (end), and into sleeve 11. Then, it is output from the prism 10 at the other end of sleeve 11 and transmitted to turntable 19 through the second universal joint 12. After turntable 19 rotates, it drives the first seat 15 and the second seat 21 to rotate through the belt drive of the second transmission wheel 20, the transmission belt 18, and the first transmission wheel 16. Since the upper and lower gears rotate in opposite directions, the rotation directions of the two seats are also opposite. The bolt and nut rotate in opposite directions in the same direction, thereby achieving the effect of rapid tightening.

[0103] By incorporating a combination of universal joints, prisms, and sleeves in the transmission chain, the geometric changes during power transmission are resolved. During operation, the two housings 8 continuously move closer to or further away from each other, causing a constant change in the spatial state of the entire transmission shaft. This change manifests in two dimensions: firstly, the deflection of the axis angle—when housing 8 is displaced relative to box 1, the transmission shaft no longer maintains an ideal straight line but instead exhibits a certain angle; secondly, the shortening of the effective length of the transmission shaft—as the two housings approach each other, the transmission shaft connecting the two ends needs to be physically shortened to accommodate the reduced distance.

[0104] Universal joints are specifically designed to address angular deflection issues. They can stably transmit rotational torque from one end to the other even when the drive shaft is at an angle, compensating for angular deviations and ensuring uninterrupted power delivery under various angle conditions. The combination of a prism and a sleeve is specifically designed to handle changes in axial length. The prism has a non-circular, prismatic cross-section, which is inserted into a sleeve with a similarly prismatic inner hole. The two can slide relative to each other, allowing for free axial expansion and contraction, thus changing the effective working length of the drive shaft. Simultaneously, due to the structural characteristics of the prismatic cross-section, the prism cannot rotate relative to the sleeve while sliding, thus allowing for simultaneous torque transmission during expansion and contraction without slippage or loss of force.

[0105] The three components work together: the universal joint is responsible for the angular degree of freedom, the prism plus sleeve is responsible for the axial degree of freedom, and the two degrees of freedom together cover all possible geometric changes of the transmission shaft during the movement of the housing. This ensures that no matter how the housing spacing changes, the power of the motor can be stably, continuously and reliably transmitted to the end effector. This is the core mechanical foundation for the successful completion of the entire automated installation process.

[0106] During the rotation of turntable 19, the first drive wheel 16, the drive belt 18 and the second drive wheel 20 drive the first seat 15 and the second seat 21 to rotate. Since the two turntables 19 rotate in opposite directions, the first seat 15 and the second seat 21 drive the bolts and nuts to rotate, and the bolts and nuts rotate in opposite directions, thus ensuring the installation of the bolts and nuts.

[0107] Subsequently, by continuously holding the housing 8, the bolt and nut can be finally installed. After installation, the staff no longer applies gripping force to the housing 8. Under the action of the spring 7, the two housings 8 are pushed to separate from each other, so that the bolt and nut are removed from the first seat 15 and the second seat 21 respectively, so that the device can be removed for the next installation work.

[0108] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
