Description

Technical Field

[0001] This utility model relates to the field of grounding wire technology, specifically to a grounding wire device and its grounding wire clamp. Background Technology

[0002] A grounding device is a safety protection facility in an electrical system, designed to ensure that in the event of a fault or accident such as lightning strike, current can be quickly discharged through the ground wire, preventing damage to electrical equipment, electric shock accidents, and other safety hazards. The grounding clamp is one of the important components connecting the grounding wire and the grounding device in a grounding system. It ensures a stable and reliable connection of the grounding wire and effectively conducts fault current.

[0003] According to the published information on the grounding wire device and its grounding wire clamp (Publication No.: CN 105226413 B), it includes an upper clamp plate, a lower clamp plate, and clamping components for clamping the upper and lower clamp plates. The upper clamp plate is provided with pin-row holes, and a plurality of pins that can move axially within the pin-row holes are provided in the pin-row holes. The ends of the pins are provided with locking portions to prevent the pins from moving out. During the clamping process, the axially movable pins on the upper clamp plate provided by the present invention are pushed upward by the pressure of the clamped object, while some of the pins that are not pushed remain in a naturally suspended state in the pin-row holes. Due to the radial positioning effect of the pin-row holes, the pins maintain a constant radial position.

[0004] In the aforementioned application, the cooperation between components such as the pin header and the clamp plate makes it difficult to solve the problems of failing to protect the grounding wire and failing to prevent any unnecessary shaking or misalignment of the grounding wire, resulting in the grounding wire getting knotted or tangled inside the junction box, which needs to be improved. Utility Model Content

[0005] This utility model proposes a grounding wire device and its grounding wire clamp, which solves the problems mentioned in the above documents.

[0006] The technical solution of this utility model is as follows: a grounding wire device, including a grounding wire, one end of which is provided with a grounding connector, and a storage and protection component is provided on the outer wall of the grounding wire. The storage and protection component includes a junction box, the top of which is located at the bottom of the grounding wire. A rotating rod is rotatably connected to the inner wall of the junction box, and a motor is fixedly connected to the end of the rotating rod away from the junction box. A gear is passed through the circumference of the motor. A support rod is fixedly connected to the inner wall of the junction box, and a sliding groove is provided at the bottom of the support rod. A slider is slidably connected to the inner wall of the sliding groove, and a rack is fixedly connected to the bottom of the slider. A limit rod is fixedly connected to the bottom of the rack, and a slot is provided on the outer wall of the junction box.

[0007] Furthermore, there are two racks, which are symmetrical to each other along the vertical central axis of the gear. The racks and gears mesh with each other, and the grounding wire is located inside the junction box. The meshing of the racks and gears facilitates the movement of the racks when the gears rotate.

[0008] Furthermore, two slots are provided and are symmetrical to each other along the vertical central axis of the junction box. A switch is provided on the side of the motor, and the grounding wire is located on the displacement trajectory of the limit rod. The switch is designed to facilitate direct control of the motor and is easy to operate.

[0009] Furthermore, there are two support rods and sliders, which are symmetrical to each other along the vertical central axis of the gear. The slot is located on the displacement trajectory of the rack. The design of the support rods and sliders makes it easy to adjust the position of the rack and prevents the rack from moving when it is not needed.

[0010] Furthermore, two slide grooves are provided, which are symmetrical to each other along the vertical central axis of the motor. The rack is located above the grounding wire, and several limiting rods are provided. The opening of the slide grooves facilitates the movement of the rack.

[0011] Furthermore, the junction box is internally equipped with a lubrication and anti-jamming component, which includes a pressing rod. One end of the pressing rod is fixedly connected to one end of the rack. A control box is fixedly connected to the inner wall of the junction box, and a fixing plate is fixedly connected to the inner wall of the control box. A displacement plate is slidably connected to the inner wall of the control box. A push rod is fixedly connected to the side of the displacement plate, and the end of the push rod away from the displacement plate passes through the side of the control box. An oil outlet pipe passes through the top of the control box. A support rod is fixedly connected to the outer wall of the junction box, and an oil tank is fixedly connected to one end of the support rod. An adding pipe passes through the side of the oil tank. A drain pipe passes through the side of the control box, and the end of the drain pipe away from the control box passes through the side of the oil tank. The lubricating oil flows out to lubricate the gears and rack, preventing jamming.

[0012] Furthermore, a contact plate is fixedly connected to the end of the push rod away from the displacement plate. The contact plate is located on the displacement trajectory of the extrusion rod. The design of the contact plate increases the contact surface that the push rod can contact, allowing the extrusion rod to extrude more directly onto the push rod.

[0013] Furthermore, two fixing plates are provided and are symmetrical to each other along the vertical central axis of the control box. A cylindrical rod is fixedly connected to the inner wall of the control box. The end of the cylindrical rod away from the control box passes through the side of the displacement plate. The design of the cylindrical rod restricts the movement trajectory of the displacement plate and prevents the movement trajectory of the displacement plate from deviating.

[0014] Furthermore, a spring is fixedly connected to the inner wall of the control box, and the end of the spring away from the control box is fixedly connected to the side of the displacement plate. The spring is designed so that the displacement plate can automatically reset when it is not compressed.

[0015] The grounding clamp of the grounding device includes a clamp, one end of which is fixedly connected to a handle, and the side of the handle is provided with a pinch handle. There are two pinch handles, which are symmetrical to each other along the vertical central axis of the clamp. The clamp is made of copper, which has good conductivity and corrosion resistance and is suitable for most electrical grounding systems. Copper grounding clamps are widely used in high current grounding requirements.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the interaction between the junction box, rotating rod, gear, rack, and other components inside the protective assembly achieves the function of the limiting rod. This prevents the grounding wire from getting tangled or twisted inside the junction box. If the grounding wire is not effectively fixed, it may come into contact with other components or become entangled, thereby affecting current conduction or causing electrical faults. By controlling the limiting rod, the grounding wire can be kept in an orderly arrangement inside the junction box, ensuring that it is always in a fixed position and avoiding any unnecessary shaking or misalignment. The movement of the limiting rod is automated by driving the gear and rack with a motor. This automated design ensures that the grounding wire is continuously and stably limited, and avoids errors caused by human operation. The motor-driven system is more reliable and consistent than manual operation, reducing the possibility of mechanical failures or operational errors.

[0018] 2. In this utility model, through the cooperation of components such as the extrusion rod, the control box, and the oil outlet pipe inside the lubrication and anti-jamming assembly, the lubricating oil can reduce friction during gear meshing, reduce wear, and ensure the smooth operation of gears and racks, thereby extending the service life of mechanical components and improving work efficiency. The relative movement of the rack causes the displacement plate inside the control box to move, thereby opening the gap between the fixed plates, allowing the lubricating oil to flow from the front layer to the rear layer of the control box, and finally flow out through the oil outlet pipe. This mechanism ensures that the lubricating oil can lubricate the gears and racks in a timely manner when needed, avoiding waste and excessive accumulation of lubricating oil, thereby achieving precise oil quantity control, ensuring smooth rack operation, and preventing jamming of the limit rod movement.

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-3 As shown, this embodiment proposes a grounding wire device and its grounding wire clamp, including a grounding wire 1, a grounding connector 2 at one end of the grounding wire 1, a storage and protection component 3 on the outer wall of the grounding wire 1, the storage and protection component 3 including a junction box 31, the top of the junction box 31 being located at the bottom of the grounding wire 1, a rotating rod 32 being rotatably connected to the inner wall of the junction box 31, a motor 33 being fixedly connected to the end of the rotating rod 32 away from the junction box 31, a gear 35 passing through the circumference of the motor 33, a support rod 36 being fixedly connected to the inner wall of the junction box 31, a sliding groove 37 being opened at the bottom of the support rod 36, a slider 38 being slidably connected to the inner wall of the sliding groove 37, a rack 39 being fixedly connected to the bottom of the slider 38, a limit rod 310 being fixedly connected to the bottom of the rack 39, and a slot 311 being opened on the outer wall of the junction box 31.

[0029] Two racks 39 are provided and are symmetrical to each other along the vertical central axis of the gear 35. The racks 39 and the gear 35 mesh with each other. The grounding wire 1 is located inside the junction box 31. The meshing of the racks 39 and the gear 35 is beneficial to drive the racks 39 to move when the gear 35 rotates.

[0030] Two slots 311 are provided and are symmetrical to each other along the vertical central axis of junction box 31. A switch 34 is provided on the side of motor 33. Grounding wire 1 is located on the displacement trajectory of limit rod 310. The design of switch 34 makes it convenient to directly control motor 33 and facilitates operation.

[0031] There are two support rods 36 and sliders 38, which are symmetrical to each other along the vertical central axis of the gear 35. The slot 311 is located on the displacement trajectory of the rack 39. The design of the support rods 36 and sliders 38 makes it easy to adjust the position of the rack 39 and prevents the rack 39 from moving when it is not needed.

[0032] Two slide grooves 37 are provided and are symmetrical to each other along the vertical central axis of the motor 33. The rack 39 is located above the grounding wire 1. Several limit rods 310 are provided. The opening of the slide grooves 37 facilitates the movement of the rack 39.

[0033] In this embodiment, the grounding wire 1 is located inside the junction box 31 for safekeeping and protection, reducing direct contact with the outside world. The grounding connector 2 and the clamp 6 are exposed through a rectangular slot, without affecting normal use. To prevent the grounding wire 1 from getting tangled or messy inside the junction box 31, a limiting rod 310 is used to limit the grounding wire 1. Pressing the switch 34 starts the motor 33. The rotation of the motor 33 drives the gear 35 to rotate. The gear 35 meshes with the two racks 39. When the motor 33 rotates forward, it drives the gears 35 to rotate. When wheel 35 rotates clockwise, gear 35 drives two racks 39 to move relative to each other. This relative movement of the racks 39 drives several limit rods 310 to rotate clockwise. The limit rods 310 are located on the side of the grounding wire 1. When the limit rods 310 rotate, they rotate onto the grounding wire 1, locking it in place and limiting its movement. This prevents the grounding wire 1 from swaying or becoming disordered inside the junction box 31. The function of the limit rods 310 is to prevent the grounding wire 1 from getting tangled or knotted inside the junction box 31. If the grounding wire 1 is not effectively secured, it may come into contact with other components or become entangled, affecting current conduction or causing electrical faults. The limit rods 310 control the grounding wire 1 to maintain an orderly arrangement inside the junction box 31, ensuring it remains in a fixed position and avoiding any unnecessary shaking or misalignment. The protection and management design of the grounding wire 1 reduces interference from the external environment and lowers the risk of electrical accidents caused by problems with the grounding wire 1. For example, if the grounding wire 1 becomes loose or comes into contact with an external metal object, it may cause safety problems such as leakage or short circuit. Through an effective limit system, the position of the grounding wire 1 is fixed, which helps to prevent this from happening and thus improves the overall safety of the equipment. The movement of the limit rod 310 is automated by the motor 33 driving the gear 35 and rack 39. This automated design can ensure that the grounding wire 1 is continuously and stably limited and can avoid human error. The motor 33 drive system is more reliable and consistent than manual operation, reducing the possibility of mechanical failure or operational error.

[0034] Example 2

[0035] like Figures 3-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes another embodiment. A lubrication and anti-jamming component 4 is provided inside the junction box 31. The lubrication and anti-jamming component 4 includes a pressing rod 41, one end of which is fixedly connected to one end of a rack 39. A control box 42 is fixedly connected to the inner wall of the junction box 31. A fixing plate 43 is fixedly connected to the inner wall of the control box 42. A displacement plate 44 is slidably connected to the inner wall of the control box 42. A push rod 47 is fixedly connected to the side of the displacement plate 44. The end away from the displacement plate 44 passes through the side of the control box 42. The top of the control box 42 has an oil outlet pipe 46. A support rod 411 is fixedly connected to the outer wall of the junction box 31. One end of the support rod 411 is fixedly connected to an oil tank 412. An addition pipe 413 passes through the side of the oil tank 412. A drain pipe 410 passes through the side of the control box 42. The end of the drain pipe 410 away from the control box 42 passes through the side of the oil tank 412. The lubricating oil flows out to lubricate the gear 35 and the rack 39 to prevent jamming.

[0036] The end of the push rod 47 away from the displacement plate 44 is fixedly connected to a contact plate 48. The contact plate 48 is located on the displacement trajectory of the extrusion rod 41. The design of the contact plate 48 increases the contact surface that the push rod 47 can contact, so that the extrusion rod 41 can more directly extrude onto the push rod 47.

[0037] Two fixed plates 43 are provided and are symmetrical to each other along the vertical central axis of the control box 42. A cylindrical rod 45 is fixedly connected to the inner wall of the control box 42. The end of the cylindrical rod 45 away from the control box 42 passes through the side of the displacement plate 44. The design of the cylindrical rod 45 restricts the movement trajectory of the displacement plate 44 and prevents the movement trajectory of the displacement plate 44 from deviating.

[0038] A spring 49 is fixedly connected to the inner wall of the control box 42. The end of the spring 49 away from the control box 42 is fixedly connected to the side of the displacement plate 44. The spring 49 is designed so that the displacement plate 44 can automatically reset when it is not compressed.

[0039] The grounding clamp of the grounding device includes a clamp 6, one end of which is fixedly connected to a handle 5. The side of the handle 5 is provided with a pinch handle 7. There are two pinch handles 7, which are symmetrical about each other along the vertical central axis of the clamp 6. The clamp 6 is made of copper, which has good conductivity and corrosion resistance and is suitable for most electrical grounding systems. Copper grounding clamps are widely used in high current grounding requirements.

[0040] In this embodiment, the rack 39 moves relative to the control box 42. This relative movement causes the pressing rod 41 to move, and the contact plate 48 is located on the movement trajectory of the pressing rod 41. When the pressing rod 41 moves, it presses against the contact plate 48. When the contact plate 48 is pressed, it causes the push rod 47 to move inwards towards the control box 42. This movement of the push rod 47 towards the control box 42 causes the displacement plate 44 to move. The two fixed plates 43 and the displacement plate 44 together control the control box 42. The internal structure is divided into two layers, front and back. The unblocking pipe 410 is located in the front layer inside the metering box 42, so the lubricating oil is initially located in the front layer inside the metering box 42. The oil outlet pipe 46 is located in the rear layer inside the metering box 42, so the lubricating oil cannot flow out initially. When the displacement plate 44 moves, a gap appears between the two fixed plates 43, allowing the lubricating oil in the front layer to flow through the gap to the rear layer of the metering box 42, and then flow out through the oil outlet pipe 46. The oil outlet pipe 46 is located away from the metering box 42. The end is located above gear 35 and rack 39, so when lubricating oil flows out, it can lubricate gear 35 and rack 39. Through the relative movement of gear 35 and rack 39, the lubricating oil inside push rod 47, displacement plate 44 and control box 42 can be driven to flow. This is crucial for the lubrication of gear 35 and rack 39. Lubricating oil can reduce friction when gear 35 meshes, reduce wear, and ensure the smooth operation of gear 35 and rack 39, thereby extending the service life of mechanical components and improving work efficiency. The relative movement of rack 39 causes displacement plate 44 inside control box 42 to move, thereby opening the gap between fixed plates 43, allowing lubricating oil to flow from the front layer to the rear layer of control box 42, and finally flow out through oil outlet pipe 46. This mechanism ensures that lubricating oil can lubricate gear 35 and rack 39 in time when needed, avoiding waste and excessive accumulation of lubricating oil, thereby achieving precise oil quantity control, ensuring smooth operation of rack 39, and preventing the limit rod 310 from jamming.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
