The turning plate 16 can be turned over by pulling the handle 29, the sliding seat 19 and the mounting plate 22 are pulled by the pull rope 30 to slide outwards in the turning process of the turning plate 16, the sliding seat 19 and the mounting plate 22 slide downwards in the axial direction by taking the limiting rod 18 and the rotary groove 20 as the axial direction when the limiting rod 18 enters the rotary groove 20, so that the first winding support 23 and the second winding support 25 for winding the cable are opened outwards, the pull rope 30 is separated from the turning plate 16 in the turning process of the turning plate 16, the cable can be unwound by rotating the first winding support 23 and the second winding support 25 in the reverse direction, and the first clamping plate 27 and the second clamping plate 28 are loosened under the action of the spring 24 after the unwinding is finished, so that the cable scattered outside the movable opening 14 in the unwinding process can be pulled out by pulling the cable scattered inside the movable opening 14 in the unwinding process.

In the present embodiment, unlike the conventional energy storage system, the cable is exposed to one side of the side plate 13, or is disposed inside the car body. If the cable is exposed on one side of the side plate 13, the external connection of the distribution box is really convenient, but the service life of the cable is obviously shortened. And set up inside the railway carriage or compartment body, need open door plant 4 when external block terminal at every turn. In the present embodiment, however, a great improvement is made to this. That is, the cable can be stored inside the compartment when not in use. And when in use, the coiled cable can be turned outwards to facilitate the wiring operation. As shown in fig. 1 and 2, a movable opening 14 is formed in the side plate 13, and the position of the movable opening 14 is as close as possible to the PCS cabinet 11.

As shown in fig. 3, the two sides of the opening 14 are fixed with edge plates 15, a turning plate 16 is connected between the two edge plates 15 in a turnable way, the edge plates 15 are directly fixed on the side plates 13, and the turning plate 16 can be turned by pulling a handle 29 arranged on the turning plate 16. During the turnover of the flap 16, the slide carriage 19, the mounting plate 22, and the first winding bracket 23 and the second winding bracket 25 can be pulled outwards by the pull rope 30. And the connection relationship of the slide 19 and the cross-slot slide 17 is shown in fig. 4. The cross-shaped groove of the slide rail 17 is penetrated through from both sides in the horizontal direction and from one side upward in the vertical direction, as shown in fig. 4, the rear end of the slide carriage 19 is embedded in the slide rail 17, and a limit rod 18 for limiting the position with the cross-shaped groove in the horizontal direction is provided. When the flap 16 is turned to be approximately horizontal, the slide 19 and the mounting plate 22 can be pulled to the bottom, i.e. the stop lever 18 enters the rotary slot 20, at which point the bottom surface of the slide 19 and the top surface of the slide 17 are already out of contact. Under the action of gravity, the slide carriage 19, the mounting plate 22, and the first winding bracket 23 and the second winding bracket 25 are turned downwards by taking the limiting rod 18 and the rotary groove 20 as axes, so that the first winding bracket 23 and the second winding bracket 25 for winding the cable are opened outwards.

Before this, the midpoint of the cable is clamped by the first clamping plate 27 and the second clamping plate 28 and then wound up along with the rotation of the first winding bracket 23 and the second winding bracket 25. As shown in fig. 5 and 6, the first clamping plate 27 and the second clamping plate 28 can be used for clamping a cable, not shown in the figure, and the rotation after the clamping can synchronously wind cable sections on two sides of the middle point of the cable. When the first winding support 23 and the second winding support 25 are opened outwards, the cable is directly exposed outside, and the cable can be unwound by reversely rotating the first winding support 23 and the second winding support 25. And the first clamping plate 27 and the second clamping plate 28 are loosened under the action of the spring 24 after the unwinding is finished, so that the cables scattered outside the movable opening 14 during the unwinding can be pulled out by pulling the cables scattered inside the movable opening 14 during the unwinding. Because the cable sections at two sides of the middle point of the cable are synchronously wound during winding, one side of the cable scatters on the inner side of the movable opening 14 and the other side of the cable scatters on the outer side of the movable opening 14 during unwinding. And after the first clamping plate 27 and the second clamping plate 28 loosen the cables, the cables can be pulled out and externally connected to the distribution box according to the required length. In this embodiment, the pull cord 30 is also automatically separated from the flap 16 during the turning of the flap 16 so as not to affect the unwinding.
