In actual use, the connecting wires need to be folded and placed in the junction box, which causes the connecting wires to become tangled. This means that time needs to be spent straightening the connecting wires when using them again. Therefore, we propose an intelligent distribution network automation device. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent power distribution network automation device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent power distribution automation device, comprising a working box, with two sets of fixed boxes connected to the inner wall of the working box, each set containing two fixed boxes. A drive shaft is rotatably connected to the inner wall of each fixed box, and a spiral spring is connected to the surface of the drive shaft. One end of the spiral spring is connected to the inner wall of the fixed box. A winding wheel is rotatably connected to the side of the fixed box, and a first ratchet is connected to the side of the winding wheel. A limit rod is rotatably connected between the two first ratchets. Two second ratchets are slidably connected to the surface of the limit rod, and a limit spring is sleeved on the surface of the limit rod. The sides of the two second ratchets are respectively connected to the two ends of the limit spring. The surfaces of the first ratchets mesh with the surfaces of the second ratchets. A cable is wound around the surface of the winding wheel, and one end of the cable is connected to a connector.

[0006] As a further embodiment of this utility model: the inner wall of the work box is provided with a sliding groove, and multiple sets of grid plates are slidably connected in the sliding groove, with each set of grid plates rotatably connected to a connecting shaft.

[0007] As a further embodiment of this utility model: a paddle is connected to the surface of the second ratchet, and the side of the paddle is slidably connected to the inner wall of the work box.

[0008] As a further embodiment of this utility model: one end of the drive shaft passes through the side wall of the fixed box and is connected to the center of the winding wheel.

[0009] As a further embodiment of this invention: the surface of the cable is slidably connected to the inner wall of the work box.

[0010] As a further embodiment of this utility model: the inner wall of the work box is magnetically connected with a dustproof mesh.

[0011] As a further embodiment of this invention, an electric fan is installed inside the work box.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model can precisely control the start and stop of cable winding through a ratchet mechanism. When the cable needs to be extended for use, the ratchet can prevent the winding wheel from winding under the action of the spiral spring, ensuring that the cable is kept in the required tension state. When the cable needs to be wound up after use, the ratchet can be unlocked by operating it, so that the spiral spring drives the winding wheel to wind up the cable, thus achieving precise control of the winding operation.

[0014] 2. By using multiple sets of grid plates, this utility model does not require a large rotation or translation space when opening the door, unlike traditional rigid doors.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 - Appendix Figure 8 This utility model discloses an intelligent power distribution automation device, comprising a working box 1. Two sets of fixed boxes 7 are connected to the inner wall of the working box 1, with two fixed boxes 7 in each set. A drive shaft 16 is rotatably connected to the inner wall of each fixed box 7. A spiral spring 15 is connected to the surface of the drive shaft 16, with one end of the spiral spring 15 connected to the inner wall of the fixed box 7. A winding wheel 12 is rotatably connected to the side of the fixed box 7, and a first ratchet 9 is connected to the side of the winding wheel 12. A limit rod 17 is rotatably connected between the two first ratchet wheels 9, and two sliding connections are made to the surface of the limit rod 17. A second ratchet 10, a limiting spring 11 is sleeved on the surface of the limiting rod 17, the sides of the two second ratchet 10 are respectively connected to the two ends of the limiting spring 11, the surface of the first ratchet 9 meshes with the surface of the second ratchet 10, the surface of the take-up wheel 12 is wound with a cable 13, one end of the cable 13 is connected to a connector 5, one end of the drive shaft 16 passes through the side wall of the fixed box 7 and is connected to the center of the take-up wheel 12, the surface of the cable 13 is slidably connected to the inner wall of the work box 1, the inner wall of the work box 1 is magnetically connected with a dustproof net 4, and an electric fan 8 is installed inside the work box 1.

[0028] In the first embodiment, the inner wall of the work box 1 is provided with a sliding groove 3, and multiple sets of grid plates 2 are slidably connected in the sliding groove 3. Each set of grid plates 2 is rotatably connected to a connecting shaft 14.

[0029] Specifically, when it is necessary to operate the equipment inside the work box 1 or store items, the grid 2 can be slid according to the needs to change the position and combination of the grid 2. During the opening or operation process, the grid 2 will not occupy a large rotation or translation space like a traditional rigid door, and can flexibly adjust the internal space layout of the work box 1 to achieve efficient utilization of the limited internal space of the work box 1.

[0030] In embodiment 2, a lever 6 is connected to the surface of the second ratchet 10, and the side of the lever 6 is slidably connected to the inner wall of the work box 1.

[0031] Specifically, the user can move the second ratchet 10 by using the lever 6, which can control the second ratchet 10 to separate from the first ratchet 9, so that the spiral spring 15 can drive the winding wheel 12 to rotate and retract the cable 13.

[0032] Working principle:

[0033] First, when cable 13 is needed, the user directly pulls connector 5 and cable 13 to move connector 5 to the working position. When cable 13 is pulled, the relative rotation between the second ratchet 10 and the first ratchet 9 can disengage. At this time, the take-up wheel 12 is not restricted by the ratchet mechanism and can freely pull cable 13. When the user releases cable 13, the second ratchet 10 can be locked on the first ratchet 9 under the elastic force of the limit spring 11, preventing the first ratchet 9 from rotating in the opposite direction. After use, the user can use the lever 6 to drive the second ratchet 10 to separate from the first ratchet 9. At this time, the spiral spring 15 releases its elastic force to drive the drive shaft 16 to rotate, thereby driving the take-up wheel 12 to rotate and wind and retract cable 13. When performing power distribution work, the electric fan 8 generates airflow, which promotes airflow inside the working box 1, removes the heat generated by the equipment operation, and plays a role in ventilation and heat dissipation, ensuring that the equipment inside the box operates stably at a suitable temperature. Thus, the entire workflow is completed.

[0034] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on.
