Description

Technical Field

[0001] The utility model relates to the technical field of energy storage management, in particular to an energy storage EMS electric energy management system. Background Art

[0002] At present, energy storage systems have the characteristics of high operating power, high grounding requirements, high isolation and withstand voltage requirements, strong anti-interference ability, and complex wiring. Taking these factors into consideration, energy storage power stations mostly use a three-level architecture battery management system, so the power management system has complex and large amounts of cables.

[0003] In the related art, in order to ensure stable docking of the wiring harness of the battery management system and reduce the failure rate, the cables of the power management system are generally collected and sorted using a cable management rack. Placing the wires in the cable management rack can shield the wires and prevent the wiring harness from loosening.

[0004] However, although this method can organize several wire harnesses, when pulling a wire harness, or when the wire harness needs to be repaired or upgraded, the wire harnesses rub against each other and are difficult to pull smoothly and quickly. Some wires that are in direct contact with the wire management rack may also be scratched. Utility Model Content

[0005] The purpose of the utility model is to provide an energy storage EMS electric energy management system to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: an energy storage EMS electric energy management system, comprising a cabinet, a plurality of brackets are installed on the back of the cabinet, and a concave wheel is installed on the bracket;

[0007] A limiting piece, the right end of which is rotatably connected to the bracket, the limiting piece is arranged in an arc shape, and the limiting piece is located above the concave wheel, and a threading hole is arranged on the surface of the limiting piece;

[0008] The wires can be clamped by the limiting piece and the concave wheel to ensure that the wires can be stuck and prevent the wires from moving freely. Each wire is limited individually to facilitate the arrangement of wires.

[0009] A tension spring is installed on the surface of the bracket, and the upper end of the tension spring is installed with the limiting plate. The tension spring is used to pull the limiting plate down to fit the concave wheel. The use of the tension spring can make the limiting plate have a certain downward pressure, which can clamp the wires and ensure that the wires will not slide freely due to their own weight.

[0010] Furthermore, a connecting seat is installed on the surface of the bracket, and a shell is rotatably connected to the connecting seat. An insertion rod and a sliding seat are slidably connected inside the shell, and both ends of the tension spring are fixedly connected to the insertion rod and the sliding seat respectively. A sliding hole is provided on the surface of the shell, and an extension rod passing through the sliding hole is inserted on the surface of the sliding seat. An adjusting ring is screwed on the surface of the shell, and twisting the adjusting ring can drive the extension rod and the sliding seat to move downward. Pulling the tension spring down on the sliding seat can make the limiting plate better press the wire, ensuring that wires of different thicknesses can be clamped.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The wires are passed through the threading holes on the limit plate between the concave wheel and the limit plate. When the wire harness is pulled, the concave wheel rotates to assist in pulling the wire harness. The resistance to pulling the wire harness is smaller, which is convenient for the wiring harness layout of the EMS power management system and is not easy to damage the wire harness.

[0013] (2) The tension of the tension spring is used to apply tension to the limit plate, so that the limit plate and the concave wheel can clamp the wire harness. When the wire harness is connected to the electrical component, the clamped wire harness will not generate downward tension, ensuring a stable connection between the wire harness and the electrical component, and preventing poor contact, thereby improving the stability of the power management system.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-5 , the utility model provides a technical solution: an energy storage EMS electric energy management system, comprising a cabinet 1, a plurality of brackets 2 are installed on the back of the cabinet 1, and a concave wheel 7 is installed on the bracket 2;

[0023] The cabinet 1 provides support and protection for the hardware used in the power management system. The wiring harnesses used between the various hardware are arranged inside the cabinet 1, and the wiring harnesses entering the cabinet 1 from the outside are wound around the concave wheel 7;

[0024] A limiting piece 8, the right end of which is rotatably connected to the bracket 2, the limiting piece 8 is arranged in an arc shape, and the limiting piece 8 is located above the concave wheel 7, and a threading hole 16 is arranged on the surface of the limiting piece 8, and the arc-shaped limiting piece 8 can cooperate with the concave wheel 7, so as to facilitate the cooperation with the concave wheel 7 to clamp the wiring harness;

[0025] A tension spring 17 is installed on the surface of the bracket 2. The upper end of the tension spring 17 is installed with the limiting plate 8. The tension spring 17 is used to pull down the limiting plate 8 to fit the concave wheel 7. When the tension spring 17 pulls down the limiting plate 8, it applies pressure to the wiring harness, which can prevent the wiring harness from moving downward due to its own weight.

[0026] In this embodiment, if Figure 2 and Figure 3 As shown, a wire inlet 5 and a screw hole 6 are provided on the back of the cabinet 1, and the bracket 2 is connected to the screw hole 6 by screws. The position of the concave wheel 7 matches the wire inlet 5, which can ensure that the wire harness passes through the wire inlet 5 smoothly after being wrapped around the concave wheel 7, thereby facilitating the connection between the wire harness and the hardware.

[0027] In this embodiment, if Figure 3 and Figure 4 As shown, a wheel frame 4 is fixedly connected to the bracket 2, and the concave wheel 7 is rotatably connected to the wheel frame 4. The wheel frame 4 ensures that the concave wheel 7 is below the limiting piece 8, thereby realizing the rotatable connection between the concave wheel 7 and the bracket 2.

[0028] In this embodiment, if Figure 3 and Figure 5As shown, a connecting seat 14 is installed on the surface of the bracket 2, and a sleeve 11 is rotatably connected to the connecting seat 14. An insertion rod 12 and a sliding seat 9 are slidably connected inside the sleeve 11. The two ends of the tension spring 17 are fixedly connected to the insertion rod 12 and the sliding seat 9 respectively. After the tension spring 17 is fixedly connected to the insertion rod 12, it is ensured that the tension spring 17 can smoothly pull the insertion rod 12 downward. A sliding hole 15 is provided on the surface of the sleeve 11, and an extension rod 18 penetrating the sliding hole 15 is inserted on the surface of the sliding seat 9. An adjusting ring 13 is screwed on the surface of the sleeve 11. When the adjusting ring 13 is screwed, the downward movement of the adjusting ring 13 can drive the sliding seat 9 to move downward through the extension rod 18, so that the sliding seat 9 can pull down the tension spring 17, and adjust the tension applied by the tension spring 17 on the limiting piece 8.

[0029] In this embodiment, if Figure 3 As shown, a hinge seat 3 is connected to the right side of the surface of the bracket 2, and a sleeve joint 10 is rotatably connected to the hinge seat 3. The sleeve joint 10 is fixedly connected to the limiting plate 8 to achieve a rotatable connection between the limiting plates 8.

[0030] Specifically, when in use, after the bracket 2 is connected to the cabinet 1, the wire is inserted into the wire threading hole 16, and then the wire is passed between the concave wheel 7 and the limit plate 8, and then the wire enters the cabinet 1 through the wire inlet 5. The concave wheel 7 of the corresponding height can be selected according to the height of the wire. When the wire is pulled, the concave wheel 7 reduces the resistance of pulling the wire by rotating, which can ensure that the pulling of the wire is not easily disturbed by foreign objects;

[0031] The adjusting ring 13 limits the upward movement of the slide 9 through the extension rod 18, ensuring that the tension spring 17 will not drive the slide 9 to move upward, so that the tension spring 17 can smoothly pull down the insertion rod 12, and the insertion rod 12 drives the limiting plate 8 to press the concave wheel 7, so that the wire is stuck by the concave wheel 7 and the limiting plate 8, ensuring that the wire will not fall, improving the stability of the connection between the wire and the hardware, and ensuring the stability of the long-term operation of the power management system.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
