The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0037] like Figure 1-4 As shown, an embodiment of the present invention provides a portable grounding wire storage rack, including a mobile frame 1 and at least two winding reels 2 fixedly connected to the mobile frame 1, the winding reels 2 are vertically spaced and distributed, and a coaxial winding tube 3 is vertically arranged on the upper side, the lower end of each winding tube 3 is rotatably connected to the corresponding winding reel 2, and the lower end is fixedly connected to a wire clamp 4 for clamping the grounding wire, each winding tube 3 is vertically penetrated with a socket 31, and each winding reel 2 is penetrated with a through hole 211 connected to the socket 31, and the hole-direction projection surface of the through hole 211 includes the projection surface of the socket 31; the portable grounding wire storage rack also includes a rotating rod 5 for inserting the socket 31 of the winding tube 3, and the mobile frame 1 is installed with a rod rack 6 for placing an insulating operating rod.

[0038] The winding drum 2 and the winding tube 3 rotatably connected thereto, and the wire clamp 4 fixedly connected to the winding tube 3 constitute a storage structure for storing the grounding wire, that is, multiple groups of grounding wires can be placed in the corresponding storage structure for storage, so that the transportation operation of multiple groups of grounding wires can be completed simultaneously through the mobile frame 1. Only one operator is required to complete the transportation operation of multiple groups of grounding wires by transporting the mobile frame 1, so as to improve the technical problems in the related technology that when operators transport multiple groups of grounding wires in a dispersed manner, there is inconvenience in transportation and a lot of manpower is consumed. During the transportation operation, , multiple insulating operating rods configured with multiple groups of grounding wires can be synchronously stored and placed in the rod rack 6 on the mobile frame 1 to complete the synchronous transportation operation; during the specific winding operation, one end of the grounding wire can be clamped in the wire clamp 4, and then the end of the rotating rod 5 is inserted from the upper end of the insertion hole 31 of the topmost winding tube 3, until the lower end of the rotating rod 5 reaches the insertion hole 31 of the winding tube 3 to be rotated, and then force is applied to the upper end of the rotating rod 5, so that the rotating rod 5 and the winding tube 3 to be rotated rotate at the same time, until the clamped grounding wire rotates around the rotating winding tube 3 until the winding operation is completed.

[0039] After the rotation is completed, the rotating rod 5 can be placed on the rod frame 6 for storage.

[0040] The mobile frame 1 includes a horizontal frame 11, a vertical frame 12 whose lower end is fixedly connected to one end of the horizontal frame 11, and two universal wheels 13 which are arranged at intervals and fixedly connected to the lower end of the horizontal frame 11. Each winding drum 2 is fixedly connected to the vertical frame 12.

[0041] When in use, the entire ground wire storage rack can be moved by the universal wheels 13. During transportation, especially when the field transportation operation is up and down the mountain, the use of the universal wheels 13 can greatly improve the efficiency of transportation.

[0042] At least two bottom columns 14 are fixed at the lower end of the horizontal frame 11, and each bottom column 14 and each universal wheel 13 are respectively located at both ends of the horizontal frame 11, and the universal wheel 13 is located directly below the vertical frame 12. After the transportation is completed, the entire storage rack can be stably placed on the ground through each bottom column 14 and each universal wheel 13.

[0043] Two shoulder straps 15 are also fixedly connected to the side of the stand 12, so that the storage rack can be carried on the back by the shoulder straps 15, so as to facilitate the power workers to carry the storage rack on the mountain.

[0044] On the basis of the above embodiment, each winding reel 2 includes a winding plate 21, an extension plate 22 and at least three vertically arranged enclosures 23; the winding plate 21 is a circular plate, and a through hole 211 is coaxially opened at the center of the winding plate 21; one end of the extension plate 22 is fixedly connected to the edge end of the winding plate 21, and the other end is fixedly connected to the vertical frame 12, so that the winding plate 21 is fixedly connected to the top of the horizontal frame 11 through the extension plate 22. Each vertically arranged enclosure 23 is circumferentially spaced with the center line of the winding plate 21 as the axis, and the lower end is fixedly connected to the upper edge of the winding plate 21.

[0045] The grounding wire is received and stored by the winding plate 21 , and the grounding wire wound on the winding tube 3 is enclosed by the enclosure plates 23 .

[0046] The bottom winding plate 21 is directly fixedly connected to the horizontal frame 11 , so that the bottom winding plate 21 is stably supported by the horizontal frame 11 .

[0047] A handle is transversely fixed to the upper end of the rotating rod 5 so that the rotating rod 5 can be rotated by the handle.

[0048] On the basis of the above embodiment, the rod frame 6 includes a rod insertion seat 61 installed on the horizontal frame 11 and a rod clamping seat 62 fixedly connected to the upper end of the vertical frame 12; the rod insertion seat 61 is provided with a plurality of slots; the rod clamping seat 62 is located directly above the rod insertion seat 61, and a plurality of clamping slots are provided on one side thereof, and a binding strap is also installed on the side with the clamping slots.

[0049] When the insulating operating rod is transported, the lower end of the insulating operating rod is placed in the slot of the rod insertion seat 61, and the upper end of the insulating operating rod is fixedly connected to the clamping mouth of the clamping rod seat 62 by a binding belt to fix the insulating operating rod.

[0050] like Figure 2-6 As shown, the insertion hole 31 is a polygonal hole, and a rotating block 51 adapted to the insertion hole 31 is fixedly connected to the lower end of the rotating rod 5 .

[0051] When the rotating rod 5 is inserted into the insertion hole 31 of the winding tube 3 to rotate the winding tube 3, the rotating block 51 cooperates with the insertion hole 31, and the rotating rotating rod 5 drives the rotating block 51 to rotate. The outer wall of the rotating block 51 abuts against the hole wall of the insertion hole 31 to realize the rotation of the winding tube 3.

[0052] It should be noted that, when the rotation operation of the winding tube 3 is completed and the rotating rod 5 is pulled out, the adjacent winding tube 3 can be adaptively and synchronously rotated so that the lower end of the rotating rod 5 can be quickly and smoothly rotated into the insertion hole 31 of the adjacent winding tube 3, thereby realizing the pulling out of the rotating rod 5.

[0053] The insertion hole 31 is a polygonal hole, which means that its cross section is polygonal. In the embodiment of the present invention, the insertion hole 31 can be a triangular hole, a square hole, a pentagonal hole, a hexagonal hole, etc.

[0054] The inner walls of both ends of the insertion hole 31 are provided with guide surfaces 311 . The guide surfaces 311 are conical in shape, and the bottom diameter thereof is larger than the diameter of the circumscribed circle of the rotating block 51 .

[0055] When the rotating rod 5 rotates the other winding tubes 3 except the topmost winding tube 3 through the rotating block 51, when the rotating rod 5 and the rotating block 51 are pulled upward or downward away from the winding tube 3, the rotating block 51 can enter the guide surface 311 in the adjacent winding tube 3 and disengage from the rotated winding tube 3. After disengagement, the winding tube 3 entered by the rotating block 51 can be rotated, and at the same time, an upward or downward force is applied to the rotating rod 5 to adjust the relative angle between the rotating rod 5 and the wound tube 3 to ensure that the rotating block 51 smoothly enters the adjacent winding tube 3.

[0056] At the same time, when the rotating block 51 is inserted into the insertion hole 31 of the uppermost winding tube 3, the uppermost guide surface 311 can guide the rotating block 51 so that the rotating block 51 can be smoothly inserted into the insertion hole 31 of the uppermost winding tube 3.

[0057] Specifically, for the upward conical guide surface 311, its bottom diameter is larger than the diameter of the circumscribed circle on the lower side of the rotating block 51, so as to ensure that the moving rotating block 51 can completely enter the guiding surface 311 of the adjacent winding tube 3 upward. For the downward conical guide surface 311, its bottom diameter is larger than the diameter of the circumscribed circle on the upper side of the rotating block 51, so as to ensure that the moving rotating block 51 can completely enter the guiding surface 311 of the adjacent winding tube 3 downward.

[0058] The insertion hole 31 is a regular polygonal hole, and the rotating block 51 is a matching regular polygonal shape, so as to quickly adjust the relative angle between the rotating rod 5 and the winding tube 3, and ensure that the rotating block 51 smoothly and quickly enters the adjacent winding tube 3.

[0059] The insertion hole 31 is a regular polygon hole, which means that its cross section is a regular polygon. In the embodiment of the present invention, the insertion hole 31 can be a regular triangle hole, a square hole, a regular pentagon hole, a regular hexagon hole, etc.

[0060] like Figure 2-6 As shown, the hole wall of the through hole 211 is provided with an annular groove 212, and the corresponding lower end outer wall of the winding tube 3 is fixed with an annular block 32 adapted and rotatably connected to the annular groove 212. The annular block 32 is clamped and installed through the annular groove 212 to ensure that the winding tube 3 is vertically arranged and stably installed relative to the winding drum 2.

[0061] In the embodiment of the present invention, the annular groove 212 may be a stepped groove, a dovetail groove, a U-shaped groove, or the like.

[0062] Moreover, except for the topmost winding tube 3, support rings 33 are fixed to the outer walls of the upper ends of the other winding tubes 3. The upper side of each support ring 33 abuts against the lower side of the winding drum 2 located above it, so that the winding tube 3 fixed to the support ring 33 can form a secondary support for the winding drum 2 through the support ring 33, thereby maintaining the stability of the cantilever structure formed by the winding drum 2.

[0063] like Figure 2-6 As shown, each wire card 4 includes a fixing seat 41 fixedly connected to the corresponding winding tube 3 and a wire pressing rod 42 threadedly connected to the fixing seat 41 . The fixing seat 41 is provided with a wire threading hole 411 , and the lower end of the wire pressing rod 42 extends downward into the wire threading hole 411 .

[0064] When the ground wire is compressed by the wire clamp 4, the end of the ground wire can be inserted into the threading hole 411 so that the end is located under the wire pressing rod 42, and then the wire pressing rod 42 is rotated until the lower end of the wire pressing rod 42 presses the ground wire against the threading hole 411.

[0065] On the basis of the above embodiment, the lower side of the fixing seat 41 and the adjacent winding plate 21 are gap-matched, with a gap of 1-5 mm to prevent friction between the relatively rotating fixing seat 41 and the winding plate 21. When the rotating grounding wire is wound to form a second layer to be accumulated on the top of the first layer, under the action of the line card 4, the gap can be used to guide the grounding wire, so that the grounding wire is quickly and smoothly accumulated on the top of the first layer.

[0066] Each line card 4 further includes a line pressing plate 43 . The middle end of each line pressing plate 43 is rotatably connected to the lower end of the corresponding line pressing rod 42 , and both ends are bent downward to form an arc shape.

[0067] When the grounding wire is compressed by the wire clamp 4, the wire pressing rod 42 is rotated to move the wire pressing plate 43 downward and compress the grounding wire into the wire pressing plate 43. The arc structure of the wire pressing plate 43 is used to limit the grounding wire to ensure the tightening effect of the wire pressing and prevent the grounding wire from being damaged or scattered due to force.

[0068] On the basis of the above embodiment, a flexible layer (not shown in the figure) is bonded and fixed to the lower side of the wire pressing plate 43. The flexible layer can be made of rubber material to form a flexible contact with the ground wire to reduce the possibility of the ground wire being crushed.

[0069] Furthermore, the depth of the arc-shaped opening formed by the flexible layer is smaller than the diameter of the grounding wire, so as to ensure an effective downward pressure on the grounding wire.

[0070] like Figure 2-7As shown, each winding tube 3 is equipped with a wire pressing plate 7, one end of each wire pressing plate 7 is vertically slidably connected to the corresponding winding drum 2, and the other end extends inwardly toward the corresponding winding tube 3.

[0071] When the winding operation of the grounding wire is realized by rotating the winding tube 3 and clamping the wire clamp 4, the grounding wire passes under the wire pressing plate 7. As the winding operation proceeds, the wire reel is pressed down by the gravity of the wire pressing plate 7 to reduce the problem of the grounding wire being messy and entangled with each other.

[0072] A vertical groove 231 is provided on the inner side of one of the enclosures 23 of the winding drum 2. The vertical groove 231 is a stepped groove or a dovetail groove, and one end of the wire pressing plate 7 is adapted and slidably connected to the vertical groove 231, so that the wire pressing plate 7 is limitedly installed on the winding tube 3 through the vertical groove 231 to prevent the two from being separated. When the wire clamp 4 rotates with the winding tube 3, the wire pressing plate 7 and the wire clamp 4 form a relative rotation.

[0073] The vertical groove 231 vertically penetrates the enclosure plate 23 to facilitate the disassembly and assembly of the wire pressing plate.

[0074] A passage is formed between the other end of each wire pressing plate 7 and the corresponding winding tube 3 for the rotating wire clamp 4 to pass through, thereby preventing the wire clamp 4 and the wire pressing plate 7 from colliding with each other.

[0075] Each of the wire pressing plates 7 is slidably connected to a wire clamp 8 , and the upper and lower ends of the wire clamp 8 extend out of the corresponding wire pressing plate 7 and form an opening 81 downward for the ground wire to pass through.

[0076] When the winding operation of the grounding wire is realized by rotating the winding tube 3 and clamping the wire clamp 4, the grounding wire passes through the opening 81 below the wire pressing plate 7, and the grounding wire is guided by the wire clamp 8. At the same time, each time the winding tube 3 is rotated one circle, the wire clamp 8 can slide laterally relative to the wire pressing plate 7, so that the distance between the wire clamp 8 and the winding tube 3 is increased or shortened, so as to ensure that the coiled grounding wire will not be messy and overlapped.

[0077] Among them, the upper end of the wire clamp 8 extends upward from the upper side of the wire pressing plate 7 to form a push-pull part, which is convenient for the operator to hold the push-pull part to move the wire clamp 8 and adjust the guiding direction of the wire clamp 8 to the grounding wire to prevent the grounding wire from being entangled during the winding process, so as to ensure the orderliness of the grounding wire winding.

[0078] Each of the wire pressing plates 7 is provided with a transverse groove 71 through-through in the thickness direction, and a slot wall of the transverse groove 71 is provided with a clamping groove 72 extending in the length direction of the wire pressing plate 7; the middle end of the wire clamp 8 is adapted and slidably connected to the transverse groove 71, and is formed with a clamping block 82 adapted and slidably connected to the clamping groove 72. The wire clamp 8 is clamped and installed through the clamping groove 72, and when a force is applied to the push-pull portion, the wire pressing plate 7 can be driven to move in the vertical direction through the wire clamp 8.

[0079] The transverse groove 71 and the clamping groove 72 both penetrate the other end of the wire pressing plate 7 along the length direction, so as to realize the disassembly and installation of the wire clamp 8.

[0080] Based on the above embodiment, the length of the wire clamp 8 extending downward from the lower end of the wire pressing plate 7 is not greater than the diameter of the grounding wire, so as to form a No. 1 wire pressing opening 83 and a No. 2 wire pressing opening 84 on the lower side of the wire pressing plate 7 and on both sides of the wire clamp 8 respectively.

[0081] When the ground wire is wound from the winding tube 3 toward the edge of the winding plate 21, the layered ground wire is pressed down to the first pressing opening 83 by the other end of the pressing plate 7, which can reduce the situation that the layered ground wire is loose upward.

[0082] When the ground wire is wound from the edge of the winding plate 21 toward the winding tube 3, the layered ground wire is pressed down to the second wire pressing opening 84 by one end of the wire pressing plate 7, which can reduce the situation that the layered ground wire is loose upward.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
