Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for energy storage converters, and in particular to a structure for preventing electric shock during maintenance of energy storage converters. Background Technology

[0002] In the closed-loop operation of a new energy storage system, the energy storage converter (PCS) is the core energy conversion hub connecting the energy storage battery with the power grid or load. Its operational stability and reliability directly determine the energy conversion efficiency, safety boundary, and service life of the entire energy storage system. It plays an irreplaceable key role in ensuring the continuous output of clean power and smoothing grid fluctuations.

[0003] Currently, the electric shock prevention measures for energy storage converter maintenance on the market are relatively simple, mostly relying on traditional electrical isolation methods, such as disconnecting the main power switch. However, in actual operation, even if the main power is disconnected, the capacitors, inductors and other components inside the converter will still store a large amount of charge, and maintenance personnel will still face the risk of electric shock when touching the relevant parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a maintenance electric shock protection structure for energy storage converters. When the residual charge is detected to drop to a safe threshold, the protection components automatically unlock, allowing maintenance personnel to carry out subsequent maintenance work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a maintenance anti-electric shock structure for an energy storage converter, comprising a device body and a cabinet door. The cabinet door is hinged to the front of the device body, and two protective components are provided on the back of the cabinet door. Each protective component includes a telescopic rod installed inside the cabinet door, a spring sleeved on the outer wall of the telescopic rod, and a movable block connected to the telescopic end of the telescopic rod. A slider, a connecting plate, and a plug are respectively connected to the movable block. An insertion hole is provided inside the device body, and the plug is adapted to the insertion hole.

[0006] As a further technical solution of this utility model, an electric push rod is installed inside the main body of the device. The output end of the electric push rod is connected to the outer wall of the connecting plate. A sliding groove adapted to the slider is opened inside the cabinet door. Two charge detection modules are installed on the back of the cabinet door. The charge detection modules cooperate with the protective components.

[0007] As a further technical solution of this utility model, a heat dissipation box is installed on the outer wall of the main body of the device, and a fan and two fixed brackets are installed inside the heat dissipation box. Dustproof nets are slidably connected inside the two fixed brackets.

[0008] As a further technical solution of this utility model, the main body of the device is provided with multiple heat dissipation holes, and a supplementary light is installed inside the main body of the device.

[0009] As a further technical solution of this utility model, a warning light is installed on the main body of the device, and an observation window is installed on the front of the cabinet door.

[0010] As a further technical solution of this utility model, four threaded cylinders are installed on the bottom surface of the main body of the device, and each threaded cylinder is threaded with a support leg inside.

[0011] As a further technical solution of this utility model, a controller is installed on the front of the cabinet door, and the controller is electrically connected to the electric push rod, the charge detection module, the fan, the supplementary light and the warning light respectively.

[0012] This utility model provides a structure for preventing electric shock during maintenance of an energy storage converter, which has the following advantages compared with the prior art:

[0013] This design presents an anti-electric shock structure for energy storage converter maintenance. Through the cooperation of a charge detection module and a protective component, the electric push rod will only drive the protective component to unlock when the residual charge drops to a safe threshold. Combined with the physical locking of the plug and socket, this creates a rigid constraint that prevents the door from opening if the threshold is not met, eliminating the risk of electric shock due to misoperation. The automatic unlocking and locking functions driven by the electric push rod, combined with the stable movement guided by the slider and groove, eliminate the need for manual operation of the mechanical structure. This simplifies the pre-maintenance preparation process, avoids the risk of human misjudgment, and improves operational convenience. At the same time, the combination of spring and telescopic rod in the protective component can buffer impact force and reduce component wear. The independent installation of the charge detection module and the protective component also facilitates separate inspection and replacement in the future, effectively extending the service life of the structure, reducing maintenance costs, and ensuring reliable operation under long-term high-frequency use. This comprehensively meets the safety and practical needs of energy storage converter maintenance scenarios. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for an anti-electric shock structure during the maintenance of an energy storage converter: it includes a main body 1 and a cabinet door 2. The main body 1 serves as the core load-bearing component of the entire converter, providing an installation foundation for internal electrical components, protective components 3, heat dissipation structures, etc. Simultaneously, by opening a socket 6 and cooperating with a plug rod 306, the cabinet door 2 is locked and positioned, forming a basic framework for safety protection. The cabinet door 2 is hinged to the front of the main body 1. Two protective components 3 are provided on the back of the cabinet door 2. The protective components 3 include a telescopic rod 301 installed inside the cabinet door 2, where the telescopic rod 301 serves as a guide for the telescopic movement of the movable block 303, restricting the movement of the movable block 303. The movable block 303 can only move in a straight line to ensure that the insertion rod 306 can be accurately aligned and inserted into the insertion hole 6, avoiding locking failure due to deviation. The outer wall of the telescopic rod 301 is fitted with a spring 302. The telescopic end of the telescopic rod 301 is connected to a movable block 303. The movable block 303 is connected to a slider 304, a connecting plate 305 and an insertion rod 306 respectively. The device body 1 has an insertion hole 6 inside. The insertion rod 306 is adapted to the insertion hole 6. The insertion hole 6 and the insertion rod 306 are adapted in size to provide an insertion positioning point for the insertion rod 306. This is the key matching structure to realize the physical locking of the cabinet door 2, ensuring that the cabinet door 2 can be stably fixed after the insertion rod 306 is inserted.

[0021] An electric push rod 307 is installed inside the main body 1 of the device. The output end of the electric push rod 307 is connected to the outer wall of the connecting plate 305. The cabinet door 2 has a sliding groove 4 that matches the slider 304. The cooperation between the slider 304 and the sliding groove 4 further restricts the movement trajectory of the movable block 303, preventing it from shaking or getting stuck during extension and retraction, and ensuring the docking accuracy of the plug rod 306 and the plug hole 6. Two charge detection modules 5 are installed on the back of the cabinet door 2. The charge detection modules 5 cooperate with the protective component 3. The charge detection modules 5 use existing technology to detect the residual charge inside the main body 1 of the device and provide real-time feedback on whether the charge has dropped to the safe threshold. When the charge exceeds the standard, the electric push rod 307 is prohibited from moving, keeping the protective component 3 locked. When the charge meets the standard, the electric push rod 307 is allowed to start, providing the unlocking of the protective component 3, thus avoiding the risk of electric shock from the source.

[0022] A heat sink 7 is installed on the outer wall of the main body 1. Inside the heat sink 7, a fan 8 and two mounting brackets 9 are installed. When the fan 8 is turned on, it can accelerate the airflow and exhaust the heat generated inside the main body 1 by the operation of the components through the heat dissipation holes 11, forming a cycle of air intake-heat dissipation-exhaust. Dustproof nets 10 are slidably connected inside the two mounting brackets 9. The dustproof nets 10 can filter dust, lint and other impurities in the air and prevent them from entering the interior of the main body 1 with the airflow, thus avoiding problems such as reduced insulation performance and obstructed heat dissipation caused by dust adhering to the surface of electrical components.

[0023] The device body 1 has multiple heat dissipation holes 11 inside, a supplementary light 12 is installed inside the device body 1, a warning light 13 is installed on the device body 1, an observation window 14 is installed on the front of the cabinet door 2, four threaded cylinders 15 are installed on the bottom of the device body 1, and a support leg 16 is threaded inside each threaded cylinder 15. A controller 17 is installed on the front of the cabinet door 2. The controller 17 is electrically connected to the electric push rod 307, the charge detection module 5, the fan 8, the supplementary light 12 and the warning light 13 respectively.

[0024] The working principle of this utility model is as follows: When maintenance is required, the main power supply is first disconnected, and then a command is initiated through the controller 17 on the front of the cabinet door 2. The two charge detection modules 5 on the back of the cabinet door 2 are immediately activated to detect the residual charge of the internal components of the device body 1 and transmit the data to the controller 17 in real time. If the charge has not dropped to the safety threshold, the controller 17 prohibits the electric push rod 307 from moving, and the protective component 3 remains locked: the spring 302 on the outer wall of the telescopic rod 301 extends naturally, the movable block 303 drives the insertion rod 306 to insert into the insertion hole 6 of the device body 1, and the slider 304 is stably positioned in the slide groove 4, physically locking the cabinet door 2; at the same time, the controller 17 triggers the warning light 13 to light up, indicating that operation is prohibited. If the charge reaches the standard, the controller 17 instructs... When the electric push rod 307 is activated, its output end pushes the connecting plate 305, causing the movable block 303 to slide along the slide groove 4, simultaneously stretching the telescopic rod 301 and the spring 302, causing the insertion rod 306 to disengage from the insertion hole 6 to complete the unlocking. The warning light 13 goes out to indicate that the door can be opened. After the cabinet door 2 is opened, if the light is insufficient, the supplementary light 12 inside the main body 1 is turned on by the controller 17. During operation or maintenance, the fan 8 inside the heat dissipation box 7 works with the multiple heat dissipation holes 11 of the main body 1 to dissipate heat. The dustproof net 10 filters impurities and is easy to clean through the sliding structure of the fixing frame 9. The four threaded cylinders 15 on the bottom of the main body 1 work with the support legs 16 to adjust the height and ensure stability. Maintenance personnel can also make a preliminary observation of the internal situation through the observation window 14 to improve operational safety.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
