[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 5 As shown, an embodiment of the present invention provides a grounding wire storage device, which includes a frame 10, a take-up drum 20, a driving member 30 and a clamping member 40. The take-up drum 20 is rotatably arranged on the frame 10, the driving member 30 is arranged on the frame 10 and is drivingly connected to the take-up drum 20 to drive the take-up drum 20 to rotate, and the clamping member 40 is movably arranged on the take-up drum 20 along the circumferential direction of the take-up drum 20. The clamping member 40 is used to fix the grounding wire, wherein an anti-retraction structure 50 is arranged between the clamping member 40 and the take-up drum 20 to allow the clamping member 40 to move along the winding direction of the take-up drum 20 and limit the reverse movement of the clamping member 40 along the winding direction of the take-up drum 20.

[0034] The grounding wire storage device provided in this embodiment includes a frame 10, a take-up drum 20, a driving member 30 and a clamping member 40. First, the grounding end of the grounding wire is fixed on the take-up drum 20, and the take-up drum 20 is driven by the driving member to rotate forward, so that the grounding wire is wound on the take-up drum 20 along the winding direction of the take-up drum 20 until the grounding wire is completely wound on the take-up drum 20, and then the clamping member 40 is moved along the winding direction of the take-up drum 20 so that the clamping member 40 is close to the grounding wire. The end of the ground wire is clamped by the clamping member 40, so that the ground wire is neatly stored on the take-up reel 20. Since an anti-retraction structure 50 is provided between the clamping member 40 and the take-up reel 20, when the take-up reel 20 is stored or transported, the anti-retraction structure 50 is utilized to limit the reverse movement of the clamping member 40 along the winding direction of the take-up reel 20, so that the clamping member 40 and the take-up reel 20 fix the grounding end and the end of the ground wire to prevent the ground wire from loosening and falling on the take-up reel 20.

[0035] like Figure 4 and Figure 5 As shown, the anti-backward structure 50 includes a reverse tooth structure 51 , which allows the clamping member 40 to move along the winding direction of the take-up drum 20 , and restricts the clamping member 40 from moving in the reverse direction of the winding direction of the take-up drum 20 .

[0036] like Figure 4 and Figure 5 As shown, the inverted tooth structure 51 includes an inverted gear ring 511 and elastic teeth 512. The inverted gear ring 511 extends along the circumferential direction of the take-up drum 20 and is arranged on the take-up drum 20. The elastic teeth 512 are arranged on the clamping member 40. The elastic teeth 512 have an engaged state and an avoidance state. When the elastic teeth 512 are in the engaged state, the elastic teeth 512 are engaged with the inverted gear ring 511 to limit the reverse movement of the clamping member 40 along the winding direction of the take-up drum 20. When the elastic teeth 512 are in the avoidance state, the elastic teeth 512 move relative to the inverted gear ring 511 along the winding direction of the take-up drum 20 to allow the clamping member 40 to move along the winding direction of the take-up drum 20.

[0037] Among them, after the grounding wire is completely wound on the take-up drum 20, the clamping member 40 is moved along the winding direction of the take-up drum 20, and the inverted gear ring 511 applies a force to the elastic teeth 512 to cause the elastic teeth 512 to elastically deform to switch to an avoidance state. The elastic teeth 512 avoid the inverted gear ring 511, so that the elastic teeth 512 move relative to the inverted gear ring 511 along the winding direction of the take-up drum 20, so that the clamping member 40 is close to the end of the grounding wire, and the end of the grounding wire is clamped by the clamping member 40. When the take-up drum 20 is stored or transported, the elastic teeth 512 are restored to the meshing state with the inverted gear ring 511 to limit the reverse movement of the clamping member 40 along the winding direction of the take-up drum 20.

[0038] like Figure 4 and Figure 5 As shown, the ground wire receiving device further includes a guide structure 60, which includes a guide groove 61 and a slider 62. The guide groove 61 extends along the circumferential direction of the take-up drum 20 and is arranged on the take-up drum 20. The inverted gear ring 511 is arranged on the inner wall of the guide groove 61. The slider 62 is fixedly arranged on the clamping member 40. The slider 62 is movably arranged in the guide groove 61 along the extension direction of the guide groove 61. The elastic teeth 512 extend into the guide groove 61 and can mesh with the inverted gear ring 511. The above-mentioned guide structure 60 is adopted, and the guiding effect of the guide groove 61 on the slider 62 is utilized to facilitate the determination that the moving trajectory of the clamping member 40 relative to the take-up drum 20 extends in the direction of the take-up drum 20, and the matching reliability of the inverted gear ring 511 and the elastic teeth 512 is improved.

[0039] like Figure 5 As shown, the clamping member 40 includes a fixed clamp 41, a movable clamp 42 and a reset member. The fixed clamp 41 is movably arranged on the wire take-up drum 20 along the circumferential direction of the wire take-up drum 20. The movable clamp 42 is hinged to the fixed clamp 41. The clamping member 40 has a clamping state and a released state. When the clamping member 40 is in the clamping state, the clamping end of the fixed clamp 41 abuts against the clamping end of the movable clamp 42. The fixed clamp 41 and the movable clamp 42 are arranged to form a clamping hole. When the clamping member 40 is in the released state, the clamping end of the fixed clamp 41 is separated from the clamping end of the movable clamp 42. The reset member is arranged between the movable clamp 42 and the wire take-up drum 20 to apply a reset force to the movable clamp 42 to reset the clamping member 40 to the clamping state. The clamping member 40 with the above structure is adopted. By operating the movable clamp 42, the movable clamp 42 is made to swing relative to the fixed clamp 41, so that the clamping member 40 is switched to the released state, thereby facilitating the placement of the end clamp of the grounding wire between the fixed clamp 41 and the movable clamp 42. Then the movable clamp 42 is released, and the reset member applies a reset force to the movable clamp 42 to reset the clamping member 40 to the clamping state, so that the clamping member 40 is switched to the clamping state. At this time, the grounding wire is passed through the clamping hole, and the clamping member 40 fixes the end of the grounding wire. The anti-retraction structure 50 is arranged between the fixed clamp 41 and the take-up reel 20 to indirectly limit the reverse retreat of the end of the grounding wire along the winding direction of the take-up reel 20 to prevent the grounding wire from loosening and falling on the take-up reel 20.

[0040] Specifically, the end of the grounding wire has an end clamp, and the clamping member 40 is switched to a clamping state. At this time, the grounding wire is passed through the clamping hole, and the end clamp is clamped at the clamping hole to connect the end of the grounding wire and the clamping member 40. During the transportation and storage of the take-up reel 20, the clamping member 40 is prevented from loosening or falling off, thereby protecting the integrity of the clamping member 40 and avoiding potential safety risks.

[0041] In this embodiment, the elastic teeth 512 and the fixing clip 41 are both disposed on the slider 62 .

[0042] like Figure 2 and Figure 3 As shown, the take-up drum 20 has a rotating shaft 21 extending along its axial direction, and the grounding wire storage device includes a locking fixture 70 arranged on the frame 10, and the locking fixture 70 includes a fixing fixture 71, a locking pin 72 and an elastic member. The fixing fixture 71 is arranged on the frame 10, and the upper end of the fixing fixture 71 is provided with a positioning groove 711 extending along the axial direction of the take-up drum 20, and the rotating shaft 21 can be rotatably extended into the positioning groove 711 around its axis, and the locking pin 72 can be movably arranged on the fixing fixture 71, and the locking pin 72 has a locked state and an unlocked state. When the locking pin 72 is in the locked state, the locking pin 72 closes the notch of the positioning groove 711, and when the locking pin 72 is in the unlocked state, the locking pin 72 opens the notch of the positioning groove 711, and the elastic member is arranged between the locking pin 72 and the fixing fixture 71 to apply a reset force to the locking pin 72 to reset it to the locked state. When the take-up reel 20 is damaged or unsuitable, the lock pin 72 is switched to the unlocked state, the lock pin 72 opens the notch of the positioning slot 711, and the shaft 21 can enter and exit the positioning slot 711, so that the take-up reel 20 can be disassembled relative to the frame 10, so that the take-up reel 20 can be replaced and the storage requirements of grounding wires of different specifications can be met. After the take-up reel 20 is installed in place, the lock pin 72 is released, and the elastic member applies a reset force to the lock pin 72 to reset the lock pin 72 to the locked state, and the lock pin 72 closes the notch of the positioning slot 711, and when the take-up reel 20 rotates, the shaft 21 is prevented from falling out of the positioning slot 711.

[0043] Furthermore, the bottom of the positioning groove 711 is matched with the side wall of the rotating shaft 21 to reduce the resistance during the rotation of the take-up drum 20, facilitate the smooth rotation of the take-up drum 20, and improve the storage efficiency.

[0044] like Figure 3 As shown, the ground wire storage device further includes a lifting member 81, which is disposed on the frame 10 and is drivingly connected to the fixing fixture 71 to drive the locking fixture 70 to drive the take-up reel 20 to rise and fall. When the take-up reel 20 needs to be disassembled, the lifting member 81 is used to drive the locking fixture 70 to drive the take-up reel 20 to descend, so as to reduce the operation height of removing the take-up reel 20 from the frame 10 and reduce the work intensity.

[0045] Specifically, after the take-up drum 20 is installed in place, the lifting member 81 is used to drive the locking fixture 70 to drive the take-up drum 20 to rise until the take-up drum 20 rises to the working height. At this time, the transmission chain 93 is respectively matched with the driving gear 91 and the driven gear 92.

[0046] like Figure 2As shown, the take-up reel 20 includes a core 22, a first side plate 23 and a second side plate 24. The core 22 is rotatably arranged on the frame 10 around its axis. The driving member 30 is drivingly connected to the core 22. The first side plate 23 is arranged at one end of the core 22, and the second side plate 24 is arranged at the other end of the core 22. The outer wall of the core 22, the first side plate 23 and the second side plate 24 are jointly arranged to form a winding area 25.

[0047] The barrel core 22, the first side plate 23 and the second side plate 24 provide a basic structure for the take-up drum 20 to receive the ground wire, which has the following advantages:

[0048] (1) The overall strength and rigidity of the take-up drum 20 are enhanced to prevent the take-up drum 20 from being deformed or damaged by external forces during the process of taking up and transporting the wires, thereby providing a stable support for the ground wire;

[0049] (2) The outer wall of the barrel core 22, the first side plate 23 and the second side plate 24 are used together to enclose a winding area 25, which limits the winding range of the grounding wire and avoids excessive winding or crossing of the grounding wire when winding it, thereby reducing the friction between different parts of the grounding wire and reducing the risk of wear on the insulation layer of the grounding wire, while making the storage process more orderly and beautiful.

[0050] In this embodiment, the take-up drum 20 is made of steel, so that the take-up drum 20 not only has sufficient strength to bear the weight of the grounding wire, but also has good corrosion resistance, can adapt to the complex environment in the substation, and extend the service life of the device.

[0051] In this embodiment, the barrel core 22, the first side plate 23 and the second side plate 24 are detachably connected, so that the wire taking-up reel 20 is composed of the barrel core 22, the first side plate 23 and the second side plate 24 in a modular assembly. When the wire taking-up reel 20 is damaged or needs to adapt to grounding wires of different specifications, the barrel core 22, the first side plate 23 or the second side plate 24 can be easily replaced, thereby improving the flexibility and practicality of the device and reducing maintenance and replacement costs.

[0052] like Figure 2 As shown, a hanging hole 26 is provided on the take-up drum 20. After the take-up drum 20 is finished taking up the wire, the take-up drum 20 is removed from the frame 10, and the hanging hole 26 is used to hang the take-up drum 20, and before the take-up drum 20 takes up the wire, the hanging hole 26 is used to fix the grounding end of the grounding wire.

[0053] Specifically, the grounding end of the grounding wire has a grounding clamp, which is clamped at the hanging hole 26 to connect the grounding end of the grounding wire and the take-up reel 20. During the transportation and storage of the take-up reel 20, the grounding clamp is prevented from loosening or falling off, thereby protecting the integrity of the grounding clamp and avoiding potential safety risks.

[0054] like Figure 1 As shown, the ground wire storage device further includes a handle 82, which is disposed on the wire reel 20, and the middle portion of the handle 82 is disposed above the wire reel 20. After the wire reel 20 is wound up, the wire reel 20 is lifted by the handle 82, so that the wire reel 20 can be removed from the frame 10 and carried, and the wire reel 20 can be placed in the storage cabinet.

[0055] like Figure 1 As shown, the ground wire storage device also includes a driving gear 91, a driven gear 92 and a transmission chain 93. The driving gear 91 is arranged on the frame 10, the driving member 30 is drivingly connected to the driving gear 91, the driven gear 92 is coaxially connected to the take-up drum 20, and the transmission chain 93 is sleeved on the driving gear 91 and the driven gear 92. The driving member 30 drives the driving gear 91 to rotate, and the driving gear 91 drives the driven gear 92 to rotate through the transmission chain 93, thereby driving the take-up drum 20 to rotate to store the ground wire.

[0056] In this embodiment, the driving gear 91, the driven gear 92 and the transmission chain 93 are used to stably, efficiently and flexibly transmit torque between the driving member 30 and the take-up drum 20, thereby solving the high labor intensity problem of manual take-up, improving the efficiency and safety of take-up, and having the following beneficial effects:

[0057] (1) The driving gear 91, the driven gear 92 and the transmission chain 93 can adapt to complex working conditions such as dust, humidity and high temperature, and have good wear and corrosion resistance, and can work stably for a long time in the special environment of the substation;

[0058] (2) The driving gear 91, the driven gear 92 and the transmission chain 93 can efficiently transmit power and have a high transmission efficiency. The transmission chain 93 can withstand a large pulling force and torque, ensuring that the power output by the driving member 30 can be stably and losslessly transmitted to the take-up reel 20, thereby improving the working efficiency and reliability of the entire device;

[0059] (3) By adjusting the size of the driving gear 91 and the driven gear 92 and the length of the transmission chain 93, the transmission ratio can be flexibly changed to adapt to different specifications of the take-up reel 20 and different lengths of ground wires. In addition, the use of the transmission chain 93 is also convenient for maintenance and adjustment of the equipment. The driving gear 91, the driven gear 92 or the transmission chain 93 can be easily replaced as needed;

[0060] (4) The manufacturing cost of the driving gear 91, the driven gear 92 and the transmission chain 93 is relatively low, and they are easy to maintain and do not need to be replaced frequently, so that the grounding wire storage device has good cost-effectiveness in long-term operation.

[0061] Compared with belt drive, the use of the transmission chain 93 for chain drive can provide more precise speed and position control, which helps to accurately control the take-up speed and take-up position, and ensure that the take-up drum 20 neatly stores the ground wire.

[0062] In this embodiment, the driving member 30 includes a driving motor, and the motor shaft of the driving motor is drivingly connected to the take-up drum 20. For the high-voltage grounding wire, due to its large length and weight, the operator needs to spend a lot of physical strength to complete the storage using the double-hook manual storage method in the related art, and the work intensity is particularly high. In this embodiment, the driving motor is used to provide the power required for the rotation of the take-up drum 20, and the grounding wire is stored electrically to reduce the work intensity.

[0063] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
