[0050] Embodiment 1

[0051] like Figures 1 to 7 As shown, the power grid with a broken line recovery function of this embodiment includes a mounting frame 100 , a transformer 200 , a plurality of clamping mechanisms 300 , a plurality of winding mechanisms 400 , a plurality of conductive rods 500 and a plurality of conductive wires 610 .

[0052] Wherein, the transformer 200 is installed on the mounting frame 100;

[0053] A plurality of clamping mechanisms 300 are arranged at intervals on the top of the transformer 200 along the X direction. The clamping mechanism 300 includes a first driving component 310 and a clamping portion 320 installed on the top of the transformer 200. The clamping portion 320 is electrically connected to the transformer 200. The first driving component 310 is connected to the clamping portion 320. The first driving component 310 can drive the clamping portion 320 to open or close.

[0054] The winding mechanism 400 corresponds to the clamping mechanism 300 one by one. The plurality of winding mechanisms 400 are located above the transformer 200 and are arranged at intervals along the X direction. The winding mechanism 400 includes a second driving assembly 410 and a roller 420 mounted on the mounting frame 100. The second driving assembly 410 is connected to the roller 420. The axial direction of the roller 420 extends along the X direction.

[0055] The conductive rod 500 is mounted on the mounting frame 100 and is located above the winding mechanism 400. The conductive wire 610 is wound on the roller 420, and one end of the conductive wire 610 is connected to the conductive rod 500, and the other end is selectively connected to the clamping portion 320.

[0056] When the wire 610 is broken, the first driving assembly 310 drives the clamping portion 320 to open to disconnect the wire 610 from the clamping portion 320 , and the second driving assembly 410 drives the roller 420 to wind the wire 610 .

[0057] In this embodiment, the transformer 200 is mounted on the mounting frame 100 and connected to the conductive rod 500 through the wire 610, and the external wiring harness is connected through the conductive rod 500. In the absence of the winding mechanism 400, if the wire 610 is used for a long time and causes fatigue fracture, the broken wire 610 is easy to overlap on the grid and cause a safety hazard of leakage. In the winding mechanism 400 in this embodiment, after the wire 610 is wound on the roller 420, the two ends of the wire 610 are respectively connected to the clamping part 320 connected to the transformer 200 and the conductive rod 500. When the wire 610 is in normal use, the second driving component 410 drives the roller 420 to wind the wire 610, so that the wire 610 remains in a tensioned state; when the wire 610 is broken, the first driving component 310 drives the clamping part 320 to open to disconnect the wire 610 from the clamping part 320, and the second driving component 410 drives the roller 420 to wind the wire 610 to recover the broken wire, thereby avoiding the safety hazard of leakage caused by the broken wire 610 overlapping the grid.

[0058] Further, the mounting frame 100 includes a first substrate 110, a second substrate 120 and a third substrate 130 which are spaced apart from each other from bottom to top, and two columns 140 which penetrate the first substrate 110, the second substrate 120 and the third substrate 130, and the two columns 140 are spaced apart along the X direction, the transformer 200 is mounted on the first substrate 110, and the second driving assembly 410 and the roller 420 are mounted on the second substrate 120; Figure 3 As shown, the power grid frame also includes a plurality of first springs 710 and a plurality of proximity switches 720, the conductive rod 500 includes a conductive rod body 510 and a first limit plate 520 and a second limit plate 530 arranged around the outer periphery of the conductive rod body 510, the conductive rod body 510 passes through the third substrate 130, and a first spring 710 is sleeved on the outer periphery of each conductive rod body 510, the first limit plate 520 is located above the third substrate 130, the proximity switch 720 is installed on the side of the first limit plate 520 facing the third substrate 130, and the second limit plate 530 is located below the third substrate 130, the two ends of the first spring 710 are respectively connected to the third substrate 130 and the second limit plate 530, and the lower end of the conductive rod body 510 is connected to the wire 610.

[0059] The first spring 710 makes the proximity switch 720 at the bottom of the first limit plate 520 always have a tendency to move in a direction away from the third substrate 130, and the second drive assembly 410 can drive the roller 420 to wind the wire 610, and by tensioning the wire 610, the first limit plate 520 and the conductive rod body 510 overcome the force of the first spring 710 and move in a direction close to the third substrate 130, and make the proximity switch 720 installed at the bottom of the first limit plate 520 abut against the third substrate 130. When the wire 610 is broken, the first spring 710 drives the conductive rod 500 to move upward, so that the proximity switch 720 moves upward, and the proximity switch 720 is separated from the third substrate 130, triggering the first drive assembly 310 to drive the clamping part 320 to open and the second drive assembly 410 to drive the roller 420 to wind the broken wire 610.

[0060] The mounting frame 100 of the present embodiment further includes a base 150 , which is fixed to the bottoms of the two upright posts 140 . The base 150 can be fixed to the ground by bolts.

[0061] Furthermore, if Figure 1 As shown, it also includes a third driving assembly 800, which is installed on the column 140 and connected to the second substrate 120. The third substrate 130 is slidably matched with the two columns 140, and the third driving assembly 800 can drive the second substrate 120 to move up and down along the column 140.

[0062] In this embodiment, the third driving assembly 800 drives the second substrate 120 and the second driving assembly 410 and the roller 420 installed on the second substrate 120 to move up and down. When the second driving assembly 410 drives the roller 420 to wind the wire 610, and the two ends of the wire 610 are respectively connected to the conductive rod body 510 and the clamping portion 320, the third driving assembly 800 can assist the second driving assembly 410 to pull down the conductive rod 500, so that the proximity switch 720 at the bottom of the first limiting plate 520 abuts against the third substrate 130.

[0063] Further, the column 140 is provided with first slide grooves 141 on both sides along the Y direction, and the length of the first slide groove 141 extends along the vertical direction. The second substrate 120 is provided with a through hole 121 matched with the column 140, and the hole wall of the through hole 121 is provided with a first slider 122 facing the first slide groove 141. Figure 5 The third driving assembly 800 includes a plurality of first electric push rods 810 , and a first electric push rod 810 is installed on the bottom wall of each first slide slot 141 , and the first electric push rod 810 is connected to the first sliding block 122 .

[0064] In this embodiment, a first slide groove 141 is opened on the outer side of the column 140, and a first electric push rod 810 is installed on the bottom wall of the first slide groove 141. The first electric push rod 810 drives the first slider 122 to drive the entire second substrate 120 and the winding mechanism 400 to move up and down, so as to achieve the abutment between the proximity switch 720 and the third substrate 130.

[0065] The first slider 122 is a cross-shaped structure, which plays a role of limiting, and the structure of the first slide slot 141 matches the shape of the first slider 122. One end of the first slide slot 141 along the vertical direction can be designed as an open structure to facilitate the assembly of the second substrate 120 and the column 140.

[0066] Exemplarily, the second substrate 120 is provided with mounting holes 123 spaced apart along the X direction, and the mounting holes 123 penetrate the second substrate 120 along the vertical direction. Multiple rollers 420 are connected by a fixed shaft 430, and the length of the fixed shaft 430 extends along the Y direction. Both ends of the fixed shaft 430 are rotatably connected to the hole walls of the mounting holes 123. The second driving assembly 410 is at least one group, and each group of the second driving assembly 410 includes a motor 411, a first bevel gear 412 and a second bevel gear 413. The motor 411 is installed on the outer side wall of the mounting hole 123 of the second substrate 120 along the Y direction and is transmission-connected to the first bevel gear 412 through an output shaft, and the length of the output shaft extends along the Y direction. The second bevel gear 413 is fixed on the fixed shaft 430, and the first bevel gear 412 is meshed with the second bevel gear 413. The motor 411 can drive the first bevel gear 412 to drive the second bevel gear 413 to rotate, and the second bevel gear 413 drives the fixed shaft 430 to drive the roller 420 to rotate, thereby realizing the winding operation of the wire 610.

[0067] In this embodiment, a set of second driving components 410 is disposed between every two adjacent rollers 420 to improve the efficiency of the winding operation of the wire 610 .

[0068] Furthermore, two baffles 124 are provided between each two adjacent rollers 420, and the two ends of the two baffles 124 along the Y direction are respectively fixedly connected to the hole wall of the mounting hole 123, and the two baffles 124 are spaced apart along the X direction, and the first bevel gear 412 and the second bevel gear 413 are located between the two baffles 124. Figure 4 As shown, there are three rollers 420 and two groups of second drive assemblies 410. By setting a baffle 124 between two adjacent rollers 420, the installation stability of the fixed shaft 430 and the roller 420 can be improved, and the first bevel gear 412 and the second bevel gear 413 can also be protected.

[0069] Furthermore, the clamping portion 320 includes two clamping jaws 321, and the first driving component 310 includes two groups of second electric push rods 311 installed on the top of the transformer 200, each group of second electric push rods 311 is connected to one of the clamping jaws 321, and the two second electric push rods 311 can drive the clamping jaws 321 to open or close. When the two clamping jaws 321 are closed, a closed-loop structure is formed, and the wire 610 is connected to the closed-loop structure. When the two clamping jaws 321 are opened, the wire 610 is separated from the clamping jaws 321.

[0070] It is understandable that the closed jaws 321 are designed as a closed loop structure, which can facilitate the connection between the wire 610 and the clamping portion 320. When the wire 610 breaks, the first drive assembly 310 drives the two jaws 321 to open, so that the wire 610 automatically detaches from the clamping portion 320.

[0071] In order to further improve the connection stability between the wire 610 and the clamping part 320 in the closed state and the smoothness of the separation of the wire 610 from the clamping part 320 in the open state, the present embodiment further provides a first connection ring 620 and a second connection ring 630. The wire 610 is wound on the drum 420, and one end of the wire 610 is connected to the first connection ring 620, and the other end is connected to the second connection ring 630. The two clamping claws 321 of the clamping part 320 pass through the first connection ring 620 and then close, so that the connection between the first connection ring 620 and the clamping part 320 can be achieved. When the two clamping claws 321 of the clamping part 320 are opened, the first connection ring 620 immediately separates from the gap between the two clamping claws 321. A connection hole is opened at one end of the conductive rod 500 close to the transformer 200, and the second connection ring 630 is connected to the connection hole.

[0072] The winding mechanism 400 of this embodiment is particularly suitable for winding the wire 610 located above the roller 420 after it is broken.

[0073] Furthermore, if Figure 6 and Figure 7 A plurality of first mounting grooves 210 corresponding to the clamping mechanisms 300 are provided at intervals along the X direction on the top of the transformer 200. The length of the first mounting groove 210 extends along the Y direction perpendicular to the X direction. A group of second electric push rods 311 are respectively installed on two opposite groove walls of the first mounting groove 210 along the Y direction. The two clamping claws 321 are located between the two groups of second electric push rods 311.

[0074] In this embodiment, by opening a plurality of first installation grooves 210 corresponding to the clamping mechanisms 300 on the top of the transformer 200, the clamping jaws 321 corresponding to each group of clamping mechanisms 300 can be installed in the first installation grooves 210, and two second electric push rods 311 are respectively installed on two opposite groove walls of the first installation grooves 210, and the two clamping jaws 321 can be driven to move in a direction of approaching or moving away from each other by the second electric push rods 311. The first connecting ring 620 is placed between the two clamping jaws 321, and the two second electric push rods 311 respectively drive the corresponding clamping jaws 321 to move in a direction of approaching each other until they are fully closed, and the first connecting ring 620 is clamped in the closed loop structure formed by the two clamping jaws 321. When the wire 610 is broken, the second electric push rod 311 drives the two clamping jaws 321 to open, the first connecting ring 620 is separated from the two clamping jaws 321, and the second driving assembly 410 drives the roller 420 to wind the wire 610. In this embodiment, a first installation groove 210 is opened on the top of the transformer 200 to facilitate the installation of the clamping mechanism 300 .

[0075] Exemplarily, the two clamping jaws 321 are semi-circular ring structures respectively, and form a circular ring structure when the two are closed.

[0076] The clamping claw 321 is electrically connected to the circuit structure inside the transformer 200 . The circuit connection relationship is a conventional technical means in the art and will not be described in detail.

[0077] In order to further improve the stability of the second electric push rod 311 in pushing the clamping jaw 321 to move along the Y direction and prevent the clamping jaw 321 from being offset and stuck in the first mounting groove 210, this embodiment adds a guide structure for the movement of the clamping jaw 321 along the Y direction, and the guide structure includes a first guide part and a second guide part that slide together with each other.

[0078] Furthermore, the clamping portion 320 also includes a sliding seat 322, a sliding seat 322 is installed at the bottom of each clamping jaw 321, the sliding seat 322 is connected to the second electric push rod 311, a second sliding groove 220 is provided on at least one groove wall of the first mounting groove 210 along the X direction, and a second sliding block 323 is provided on the side wall of the sliding seat 322 along the X direction, and the second sliding groove 220 and the second sliding block 323 are slidably matched.

[0079] When the second electric push rod 311 pushes the clamping jaw 321 to move, the second sliding groove 220 and the second sliding block 323 slide together along the Y direction, which plays a good guiding role for the movement of the clamping jaw 321 along the Y direction.

[0080] Exemplarily, second slide grooves 220 are respectively provided on two opposite groove walls of the first mounting groove 210 along the X direction, and the length of the second slide groove 220 extends along the X direction. The notch of the second slide groove 220 faces the sliding seat 322. Correspondingly, a second slider 323 is protrudingly provided on one side of the sliding seat 322 facing the second slide groove 220. The second slider 323 slides in cooperation with the second slide groove 220. At the same time, the second slider 323 is inserted into the second slide groove 220, which can also limit the movement of the clamping jaw 321 in the vertical direction, thereby improving the movement stability of the clamping jaw 321 along the Y direction.

[0081] Embodiment 2

[0082] This embodiment is basically the same as the above-mentioned embodiment 1, except that a plurality of partition mechanisms 900 are additionally provided.

[0083] like Figures 8 to 10 As shown, along the X direction, two partition mechanisms 900 are provided between each two adjacent clamping mechanisms 300, and the partition mechanism 900 includes two partition portions 910 spaced apart along the X direction, and each partition portion 910 is transmission-connected to a corresponding sliding seat 322 via a set of transmission components 920. When the clamping portion 320 is opened, the clamping portion 320 drives the partition portion 910 to close via the transmission component 920; when the clamping portion 320 is closed, the clamping portion 320 drives the transmission component 920 to drive the partition portion 910 to separate.

[0084] In this embodiment, a partition mechanism 900 is respectively arranged on a side of each clamping mechanism 300 close to another clamping mechanism 300, and the two partition parts 910 of the partition mechanism 900 are respectively connected to the sliding seat 322 of the clamping part 320 of the corresponding clamping mechanism 300 through a transmission assembly 920. The opening or closing of the clamping part 320 can drive the transmission assembly 920 to drive the closing or opening of the two partition parts 910. When the wire 610 is broken, the two clamping claws 321 are opened and the two partition parts 910 are driven to close at the same time. The roller 420 reels the broken wire 610. The closed partition part 910 can improve the operating safety of the maintenance workers and reduce safety hazards such as electric shock. When the wire 610 is normal, the two clamping jaws 321 are closed, and the two partition parts 910 are in a separated state. There is a good ventilation effect between the adjacent clamping parts 320, which can prevent the heat dissipation of the clamping parts 320 and the top of the transformer 200 from being affected by the obstruction of the partition parts 910.

[0085] For example, there are three groups of clamping mechanisms 300. Since each group of clamping mechanisms 300 is provided with a group of partition mechanisms 900 on one side close to another group of clamping mechanisms 300, two groups of partition mechanisms 900 are provided between each two adjacent groups of clamping mechanisms 300. Fig. 9, the clamping mechanism 300 can simultaneously drive the two sets of partition mechanisms 900 on both sides to move; for the other two sets of clamping mechanisms 300, Fig.10 , which can respectively drive a group of partitioning mechanisms 900 located on the side thereof to move. Among the three groups of wires 610 connected to the three groups of clamping mechanisms 300, if any group of wires 610 is broken, the first driving assembly 310 of the corresponding clamping mechanism 300 can be triggered by the separation of the proximity switch 720 and the third substrate 130 to drive the clamping part 320 to open, release the corresponding wire 610, and at the same time drive the corresponding two groups of partitioning parts 910 to close through the clamping part 320 to block the clamping part 320 and the adjacent clamping part 320.

[0086] Furthermore, a plurality of second mounting grooves 230 are provided on the top of the transformer 200, and a second mounting groove 230 is provided between each two adjacent first mounting grooves 210. The second slide groove 220 between two adjacent clamping portions 320 extends along the X direction to the second mounting groove 230 to form a connecting cavity, and the connecting cavity is located between the first mounting groove 210 and the second mounting groove 230, and the first mounting groove 210 is connected with the second mounting groove 230 through the connecting cavity. The transmission assembly 920 includes a first rack 921, a gear 922 and a second rack 923, and the gear 922 is installed at the bottom of the second mounting groove 230. The second slider 323 passes through the connecting cavity and is connected to the first rack 921. The second rack 923 is fixed on the side of the partition portion 910 facing the corresponding clamping portion 320, and the gear 922 is respectively meshed with the first rack 921 and the second rack 923 along its circumferential sides.

[0087] The second slider 323 can move along the length direction (Y direction) of the connecting cavity. The second slider 323 serves as an intermediate connection piece between the sliding seat 322 and the first rack 921. When the two sliding seats 322 move toward each other along the Y direction, the two second sliders 323 are driven to drive the two first racks 921 to move toward each other. At this time, the first rack 921 drives the gear 922 to rotate and drives the second rack 923 to move away from each other along the Y direction, so that the two partition parts 910 are separated. When the two sliding seats 322 move toward each other along the Y direction, the two second sliders 323 are driven to drive the two first racks 921 to move away from each other. At this time, the first rack 921 drives the gear 922 to rotate in the opposite direction and drives the second rack 923 to move toward each other along the Y direction, so that the two partition parts 910 are closed.

[0088] Furthermore, the partition portion 910 includes a partition 911 and a guide assembly 912, the guide assembly 912 is installed in the second installation groove 230, the second rack 923 is fixedly connected to the partition 911, and the guide assembly 912 is connected to the partition 911 to guide the movement of the partition 911 along the Y direction to avoid the two partitions 911 from offset during movement, especially during the closing process. If offset occurs, it will affect the blocking effect between the two clamping portions 320, posing a safety hazard.

[0089] The installation position of the guide assembly 912 in this embodiment is not limited, and it can be installed on one side of the partition 911 along the Y direction, or it can be installed on the bottom of the partition 911.

[0090] Exemplarily, the guide assembly 912 includes a mounting seat 9121, a first guide rod 9122, and a first guide cylinder 9123. The mounting seat 9121 is fixed to the side of the partition 911 facing the second mounting groove 230, the first guide cylinder 9123 is fixed to the groove wall of the second mounting groove 230 along the Y direction, one end of the first guide rod 9122 is fixedly connected to the mounting seat 9121, and the other end is plugged into the first guide cylinder 9123. Of course, in other embodiments, the first guide cylinder 9123 can also be installed on the mounting seat 9121, the first guide rod 9122 is fixed to the groove wall of the second mounting groove 230, and the first guide rod 9122 is inserted into the first guide cylinder 9123 for sliding cooperation, which can also achieve the guidance of the partition 911 along the Y direction.

[0091] Furthermore, the guide assembly 912 further includes a second spring 9124, which is sleeved on the outer periphery of the first guide cylinder 9123, one end of the second spring 9124 is connected to the mounting seat 9121, and the other end is connected to the groove wall of the second mounting groove 230. By sleeved the second spring 9124 on the outer periphery of the first guide cylinder 9123, it is possible to prevent the two partitions 911 from being damaged by hard contact when closing.

[0092] In other embodiments, the guide assembly 912 is installed at the bottom of the partition 911 (not shown in the figure), including a guide rail and a guide groove opened on the guide rail. The length of the guide groove extends along the Y direction. The partition 911 is plugged into the guide groove and can slide along the length direction of the guide groove.
