Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and more specifically, particularly relates to an electric energy storage device for a power distribution cabinet. Background Art

[0002] In the field of power equipment technology, especially in the operation of civil air defense distribution cabinets, it is crucial to keep the distribution cabinets powered on continuously to ensure the normal operation of civil air defense facilities. To achieve this goal, energy storage cabinets are widely used as an effective power supply for distribution cabinets. They integrate energy storage devices and power management systems, aiming to efficiently store electrical energy and release it stably when needed, ensuring continuous and reliable power supply to the distribution cabinets.

[0003] In the prior art, for example, a storage power station cabinet disclosed in Chinese patent CN208226660U mainly includes a cabinet, a rotating solar panel assembly, a battery pack, a photovoltaic charge controller, a charge regulator, an output terminal and a discharge regulator. The energy storage cabinet makes full use of both city electricity and solar energy, optimizes the lighting conditions through the automatic rotation of the solar panel, enhances the efficiency of solar energy utilization, and is equipped with corresponding protection measures to prevent external impact and remove debris. The overall design is both environmentally friendly and energy-saving.

[0004] However, although existing energy storage cabinets have made breakthroughs in energy management and environmental protection performance, there are still obvious safety hazards in practical applications, especially in complex outdoor environments. The main manifestation is: since a large amount of electrical energy is stored inside the energy storage cabinet, once a person accidentally approaches it, especially when he is unconscious or does not take appropriate protective measures, there is a high risk of electric shock. In addition, complex external environmental factors, such as slippery floors, severe weather conditions, etc., may cause people to accidentally contact the energy storage cabinet, further increasing the possibility of electric shock accidents. Such safety hazards not only threaten the safety of personnel, but may also cause equipment short-circuit failures, affect the safe and stable operation of the distribution cabinet and energy storage cabinet, and reduce the reliability of the overall power system.

[0005] In view of the above problems, it is urgent to develop a new type of energy storage device, which can not only effectively solve the risk of electric shock in energy storage cabinets in complex environments and improve the safety protection level of personnel, but also ensure the rapid power-off protection of equipment under abnormal conditions, thereby ensuring the safe and stable operation of the distribution cabinet system. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an electric energy storage device for a distribution cabinet to solve the problem raised in the above background technology that since a large amount of electric energy is stored inside the electric cabinet, there is a great risk of electric shock when a person accidentally approaches the energy storage cabinet. Therefore, when used in a complex external environment, it is not conducive to the safe and stable operation of the equipment and has great safety hazards.

[0007] The purpose and effect of the electric energy storage device for a power distribution cabinet of the utility model are achieved by the following specific technical means:

[0008] An electric energy storage device for a power distribution cabinet, characterized by comprising:

[0009] The bottom plate adopts a rectangular plate structure; four groups of cylindrical support rods are fixed on the top of the bottom plate in a rectangular array, and springs are sleeved on the outside of the support rods; an energy storage cabinet is fixed in the middle of the top of the bottom plate, and an emergency switch is set on the rear side of the energy storage cabinet;

[0010] The induction sliding plate is a rectangular plate structure, which is slidably arranged on four sets of support rods, and a rectangular through-slot structure for the energy storage cabinet to pass through is opened in the middle of the top;

[0011] The fixed rod is a rectangular rod structure and is fixed on the top of the induction sliding plate;

[0012] The slide rail is fixed on the top of the fixed rod, and a switch control rod with an L-shaped rod structure is slidably arranged on the top of the slide rail.

[0013] Furthermore, a group of connecting rods with a cylindrical structure are fixedly arranged on the top of the three groups of support rods; a protective limit fence with a rectangular frame structure is slidably arranged on the outside of the three groups of connecting rods; a first screw is rotatably arranged on the top of one group of support rods; and the protective limit fence is provided with a through-type screw hole structure which is threadably connected to the first screw.

[0014] Furthermore, a through-type screw hole structure is provided at the lower part of the switch control rod; a second screw rod is rotatably arranged at the inner side of the slide rail, and the second screw rod is connected to the switch control rod through threaded matching.

[0015] Furthermore, a first electromagnet is fixedly disposed on the top of the bottom plate; and a second electromagnet corresponding to the position of the first electromagnet is fixedly disposed on the bottom of the inductive sliding plate.

[0016] The utility model has the following beneficial effects:

[0017] Real-time electric shock protection: When a person accidentally approaches and steps on the induction sliding plate, the sliding plate is forced to move downward, and the switch control rod is driven down through the fixed rod and the slide rail, triggering the emergency switch to quickly cut off the power supply of the energy storage cabinet. This instant power-off mechanism effectively avoids electric shock accidents caused by direct or indirect contact with the energy storage cabinet, significantly improving the level of personnel safety protection.

[0018] Leakage emergency response: The device has a built-in electromagnet system. When leakage occurs, the magnetic attraction between the first and second electromagnets causes the induction sliding plate to move down, triggering the switch control rod again to close the emergency switch, achieving double protection. This automated emergency response mechanism can quickly cut off power in the event of leakage, minimize accidents, and further improve the safety of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0028] As attached Figure 1 To Attachment Figure 6 As shown:

[0029] The utility model provides an energy storage device for a power distribution cabinet, comprising a base plate 1, a support rod 101, a spring, an induction sliding plate 2, a fixing rod 203, a slide rail 204, a switch control rod 205, a connecting rod 102, a protective limit fence 103, a first screw rod 104, a first electromagnet 105, an energy storage cabinet 201, an emergency switch 202, a second screw rod 206 and a second electromagnet 207.

[0030] Bottom plate and support rods: The bottom plate 1 adopts a rectangular plate structure, and four groups of cylindrical support rods 101 are fixedly arranged in a rectangular array at the four corners of its top. A spring is sleeved on the outside of each support rod 101 to provide elastic support for the induction sliding plate 2.

[0031] Inductive sliding plate and fixed rod: The inductive sliding plate 2 is a rectangular plate structure, which is slidably arranged on four sets of support rods 101. A rectangular through-slot structure for the energy storage cabinet 201 to pass through is provided in the middle of the top of the sliding plate. The fixed rod 203 of the rectangular rod structure is fixed on the top of the inductive sliding plate 2, providing an installation foundation for the slide rail 204.

[0032] Slide rail and switch control rod: The slide rail 204 is fixed on the top of the fixed rod 203, and the switch control rod 205 of the L-shaped rod structure is slidably arranged on the top of the slide rail 204. When the induction sliding plate 2 is pressed down due to the approach of a person, the switch control rod 205 is driven downward by the fixed rod 203 to trigger the emergency switch 202, thereby realizing the power-off protection of the energy storage cabinet 201.

[0033] Connecting rod and protective limit fence: A cylindrical connecting rod 102 is fixed on the top of the three groups of support rods 101, and a protective limit fence 103 of a rectangular frame structure is slidably arranged on the outside of the connecting rod 102. The protective limit fence 103 is threadedly matched with a first screw rod 104 rotatably arranged on the top of a group of support rods 101 through a through-type screw hole structure on the top. By rotating the first screw rod 104, the position of the protective limit fence 103 on the connecting rod 102 can be adjusted to achieve isolation protection around the energy storage cabinet 201, and the protection height can be adjusted according to actual needs.

[0034] Electromagnet system: A first electromagnet 105 is fixed on the top of the bottom plate 1, and a second electromagnet 207 is fixed at the corresponding position on the bottom of the inductive sliding plate 2. When leakage occurs in the device, current flows through the bottom plate 1 and the inductive sliding plate 2, causing the two sets of electromagnets to generate magnetism, attracting the inductive sliding plate 2 to approach the bottom plate 1, and at the same time triggering the switch control rod 205 to close the emergency switch 202, adding an additional leakage protection measure.

[0035] Energy storage cabinet and emergency switch: The energy storage cabinet 201 is fixedly arranged in the middle of the top of the bottom plate 1, and an emergency switch 202 is arranged at the rear side of the energy storage cabinet 201, which is used to quickly cut off the power supply in abnormal situations. A through-type screw hole structure is provided at the lower part of the switch control rod 205, and a second screw rod 206 is rotatably arranged inside the slide rail 204, and the second screw rod 206 is connected to the switch control rod 205 through threaded matching. By rotating the second screw rod 206, the position of the switch control rod 205 in the slide rail 204 can be adjusted to accommodate emergency switches 202 of different models or positions.

[0036] The specific steps are as follows:

[0037] Installation: Place the base plate 1 in the use area of ​​the energy storage cabinet 201 and fix the energy storage cabinet 201 on the base plate 1. According to actual safety requirements, adjust the relative position of the switch control rod 205 and the emergency switch 202 by rotating the second screw rod 206 to ensure that the two can effectively contact each other.

[0038] Turn on the protection mode: according to the use environment and safety requirements, rotate the first screw 104 and adjust the protection limit fence 103 to a suitable height to build a physical isolation barrier around the energy storage cabinet 201.

[0039] Electric shock protection and equipment power off: When a person accidentally approaches and steps on the induction sliding plate 2, the sliding plate is forced to move downward, driving the switch control rod 205 to descend through the fixed rod 203, triggering the emergency switch 202, and quickly cutting off the power supply of the energy storage cabinet 201 to prevent electric shock accidents.

[0040] Emergency treatment of leakage: When leakage occurs in the device, the magnetic attraction generated between the first electromagnet 105 and the second electromagnet 207 causes the induction sliding plate 2 to approach the bottom plate 1, triggering the switch control rod 205 again to close the emergency switch 202, thereby achieving double protection and effectively reducing the safety risks in the case of leakage.

[0041] In summary, the implementation mode of the utility model describes in detail an energy storage device for a distribution cabinet, which successfully solves the risk of electric shock when people accidentally approach the energy storage cabinet, the risk of equipment short circuit, and the safety of use in complex environments through a unique structural design and intelligent linkage mechanism, thereby improving the safety and practicality of the distribution cabinet system.
