[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-4This utility model provides a technical solution: a distributed energy storage wiring structure for a DC distribution network, including a mounting plate 1, two interfaces 2 on the mounting plate 1, and a wiring mechanism on the mounting plate 1. The wiring mechanism is provided in two sets, each set including two first fixing plates 301, two second fixing plates 302, and two first springs 304. The first fixing plates 301 are fixedly installed on the front side of the mounting plate 1, and the second fixing plates 302 are fixedly installed on the front side of the mounting plate 1. A first connecting rod 303 is fixedly installed between the first fixing plates 301 and the second fixing plates 302. Several first springs 304 are fixedly installed on the surface of the first connecting rod 303. The other end of 04 is fixedly installed with a first shrink plate 305. The shape of the first shrink plate 305 is set as arc. Multiple first shrink plates 305 are arranged in a ring array around the first connecting rod 303. By setting a wiring mechanism, the user connects the cable to the interface 2 and winds the redundant cable around multiple first shrink plates 305. When an accident occurs and the cable is pulled, the multiple first shrink plates 305 move radially towards the first connecting rod 303. The first spring 304 contracts, so that the cable in the de-redundant state becomes redundant again. The cable is no longer compacted, so that the cable can be pulled outward for a distance, thereby avoiding the occurrence of cable breakage when pulled.

[0027] Reference Figures 1-4 The bottom of the first fixed plate 301 is equipped with a first fixed pulley 306, the top of the second fixed plate 302 is equipped with a second fixed pulley 307, and the side of the first shrink plate 305 away from the spring is equipped with several first protrusions 308. By setting the first fixed pulley 306 and the second fixed pulley 307, friction between the cable and the first fixed plate 301 and the second fixed plate 302 is avoided, and the cable is prevented from being damaged due to friction. The setting of the first protrusions 308 makes the cable more neatly wound on the surface of the first shrink plate 305.

[0028] Reference Figures 1-4 The first fixed plate 301 and the second fixed plate 302 are each provided with a first limiting groove 309 on their opposite sides. The top and bottom of the first shrink plate 305 are each fixedly installed with a first limiting block 310. The first limiting block 310 is slidably sleeved inside the first limiting groove 309. By setting the first limiting block 310 and the first limiting groove 309, the movement direction of the first shrink plate 305 is restricted.

[0029] Reference Figures 1-4A first slide rail 311 and a second slide rail 312 are fixedly mounted on the front side of the mounting plate 1. A third fixing plate 313 and a fourth fixing plate 314 are slidably fitted onto the surfaces of the first slide rail 311 and the second slide rail 312, respectively. A second connecting rod 315 is fixedly mounted between the third fixing plate 313 and the fourth fixing plate 314. Several second springs 316 are fixedly mounted on the surface of the second connecting rod 315. A second contraction plate 317 is fixedly mounted on the other end of the second spring 316. Several second protrusions 318 are mounted on the side of the second contraction plate 317 away from the second spring 316. A return plate 319 is fixedly mounted on the front side of the mounting plate 1. A third spring 320 is installed between the third fixing plate 313 and the fourth fixing plate 314 and the return plate 319. A third fixed pulley 321 is installed at the bottom of the third fixing plate 313, and a fourth fixed pulley 322 is installed at the top of the fourth fixing plate 314. By setting the second shrink plate 317, after the user fixes the cable to the interface 2, the cable is wound around the surface of the upper first shrink plate 305 by the guide of the upper first fixed pulley 306, and then wound around the surface of the second shrink plate 317 by the guide of the upper second fixed pulley 307 and the third fixed pulley 321. After being guided by the fourth fixed pulley 322 and the lower first fixed pulley 306, the cable is wound around the surface of the lower first shrink plate 305, and finally exited through the lower second fixed pulley 307. When the cable is pulled, the first spring 304 and the second spring 316 contract, so that the cable in the de-redundant state becomes redundant again. At the same time, the third spring 320 contracts, and the third fixed plate 313 and the fourth fixed plate 314 drive the second shrink plate 317 to move to the left, thereby further increasing the distance that the cable can be pulled and improving the effect of preventing the cable from breaking.

[0030] Reference Figures 1-4 The third fixing plate 313 and the fourth fixing plate 314 are each provided with a second limiting groove 323 on their opposite sides. The top and bottom of the second shrink plate 317 are each fixedly installed with a second limiting block 324. The second limiting block 324 is slidably sleeved inside the second limiting groove 323. By setting the second limiting block 324 and the second limiting groove 323, the movement direction of the second shrink plate 317 is restricted.

[0031] Reference Figures 1-4The first fixing plate 301 is equipped with an anti-drag mechanism, which includes a fixing rod 401. Several bolts 402 are threaded on the surface of the fixing rod 401. The bolts 402 are distributed along a spiral route on the surface of the fixing rod 401. By setting up the anti-drag mechanism, after the user connects the cable to the interface 2, he rotates the bolts 402 to disengage the bolts 402 from the fixing rod 401, wraps the redundant cable around the surface of the fixing rod 401, and then tightens the bolts 402 so that the nut of the bolts 402 squeezes the cable, thereby fixing the cable from the fixing rod 401 to the interface 2. This prevents the cable from being violently pulled off the interface 2 when the cable is pulled, which would cause damage to the interface 2.

[0032] Specifically, the working process or principle of this DC distribution network distributed energy storage wiring structure is as follows: During use, the user connects the cable to interface 2, rotates bolt 402 to disengage it from fixing rod 401, wraps the redundant cable around the surface of fixing rod 401, and then tightens bolt 402, causing the nut of bolt 402 to press against the cable, thereby fixing the cable from fixing rod 401 to interface 2. Guided by the upper first fixed pulley 306, the cable is wrapped around the surface of the upper first contraction plate 305. Guided by the upper second fixed pulley 307 and third fixed pulley 321, the cable is wrapped around the surface of the second contraction plate 317. Finally, guided by the fourth fixed pulley 322 and the lower first fixed pulley 325… The cable 06 is guided and wound around the surface of the lower first shrink plate 305, and finally discharged through the lower second fixed pulley 307. When an accident occurs that causes the cable to be pulled, the multiple first shrink plates 305 and multiple second shrink plates 317 move radially toward the direction closer to the first connecting rod 303 and the direction closer to the second connecting rod 315, respectively. The first spring 304 and the second spring 316 contract, so that the cable in the de-redundant state becomes redundant again. The cable is no longer compact, so that the cable can be pulled outward a certain distance. At the same time, the third spring 320 contracts, and the third fixed plate 313 and the fourth fixed plate 314 drive the second shrink plate 317 to move to the left, thereby further increasing the distance that the cable can be pulled.
