Technical Field

[0001] This utility model relates to a low-voltage electricity safety real-scene model demonstration system, belonging to the technical field of power safety demonstration equipment. Background Technology

[0002] With the deployment of distributed energy equipment such as photovoltaic power generation, charging piles, and electric vehicles, electrical safety issues in low-voltage power consumption scenarios are becoming increasingly prominent. Training is needed for relevant technical personnel and users to improve their ability to identify and respond to electrical risks throughout the entire process of photovoltaic, charging pile, and electric vehicle usage.

[0003] Existing training methods mainly include: using PowerPoint presentations or 2D animations for demonstrations; using 3D modeling software; and using partial physical models. These methods have certain drawbacks: relying solely on theory lacks a sense of real-world application, making it difficult to visualize abstract concepts such as power transmission, fault arcing, and fire spread; software simulations can only display device animations but lack visually representable data; static physical models are typically single devices or partial demonstrations, unable to reproduce the fault chaining and propagation process between multiple devices in a short time; and there are certain dangers involved in demonstrating partial physical models.

[0004] Therefore, it is necessary to design a low-voltage electricity safety real-world model demonstration system to solve the problems of traditional training methods that cannot clearly demonstrate simulated phenomena, cannot intuitively display data, and that physical simulations pose certain dangers.

[0029] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Example 1

[0031] like Figure 1 As shown, a low-voltage electrical safety real-scene model demonstration system includes a model 1, a simulation unit, an alarm device, and an escape route guidance system 31. The simulation unit, alarm device, and escape route guidance system 31 are installed on the model 1.

[0032] In this embodiment, the simulation unit includes a photovoltaic panel module 21, a charging pile module 22, an electric vehicle module 23, and a fault simulation unit. The fault simulation unit includes an atomizer and LED lights. The atomizer can generate smoke, the LED lights can simulate dynamic flames, and the simulation unit can simulate fault disasters. An alarm device is connected to the photovoltaic panel module 21, the charging pile module 22, and the electric vehicle module 23, and the alarm device can issue an alarm. The escape route guidance system 31 includes embedded LED light strips, which are set on the surface of the model 1.

[0033] Reference Figure 1 Model 1 is a scaled-down simulation stage made of ABS, plaster, and metal foil.

[0034] Model 1 is a rectangular support platform. The outer shell is made of ABS injection molded parts and plaster components, with metal foil partially applied to the roof to simulate the reflective effect of a photovoltaic roof. The platform features a 1:10 scale miniature landscape of roads, parking spaces, and residential areas. The platform contains internal wiring space, cable trays, and module mounting positions. Cable trays are cut into the road and wall sections of the platform surface to embed escape guidance light strips 31.

[0035] The photovoltaic module 21 consists of several rectangular miniature photovoltaic units mounted on adjustable-angle triangular brackets. Each unit has terminals, a temperature sensor, and a low-power heating element on its back to simulate localized overheating during fault demonstrations. The photovoltaic module also reports its status on the control bus using a Modbus address. The photovoltaic module is connected to the control board via a low-voltage DC bus; simulated or actual measurement data from the temperature sensor is uploaded to the PLC.

[0036] The charging pile module 22 includes several charging positions, each equipped with a miniature charging pile exterior, a low-voltage electrical interface, and a measurement sensor. The measurement sensor can monitor current and voltage. Each pile is internally equipped with a controllable relay and a fault trigger interface, capable of simulating input voltage fluctuations and internal overloads. The charging pile module 22 is fixed to the model 1 via a magnetic interface; in this embodiment, a magnetic interface is used for fixation. It also connects to the internal bus and Modbus of the model 1 via connectors, enabling rapid electrical and communication connections.

[0037] The electric vehicle module 23 uses a scaled-down physical vehicle model. A simulated battery compartment is located beneath the vehicle body, containing a small, low-power heating element, a micro-atomizer, and an expandable thin-film bulge structure to simulate battery bulging. In this embodiment, the control board can issue control commands to operate the electric vehicle module 23. The electric vehicle module 23 is fixed to the surface of the model 1 via a magnetic interface. The output of the charging pile module 22 can be connected to the electric vehicle module 23, and its operation can be controlled individually or in groups via a Modbus cable.

[0038] The fault simulation unit is set inside model 1. The fault simulation unit includes an atomizer and LED lights. During the simulated fire step, the atomizer can exhaust the flames through the ventilation holes set on the surface of model 1. The LED lights are set at the bottom of photovoltaic panel module 21, charging pile module 22, and electric vehicle module 23. The LED lights can be used in conjunction with the atomizer to improve the visual realism and can simulate the effect of flickering flames.

[0039] In this embodiment, several sensors are arranged in the photovoltaic panel module 21, the charging pile module 22, and the electric vehicle module 23. The sensors can monitor the temperature, current, and smoke between the various devices and transmit the monitored data to the control board.

[0040] A control board is installed on the outside of Model 1, and a PLC is installed inside the control board. The PLC can control the simulation unit, and the control board can display the simulation curves of the simulation unit. In this embodiment, the PLC acts as the control unit of the entire device, capable of reading sensor data monitored by each module and sending instructions to each module to drive the alarm device and escape route guidance system 31. The control board is equipped with multiple buttons, which can control the demonstration system to operate in automatic, random, and manual modes. An emergency stop button is also provided in this embodiment. The control board can display simulated data curves such as temperature, current, voltage, and smoke concentration, and can achieve three-dimensional linkage between faults, phenomena, and data.

[0041] The alarm device includes a speaker and communicates with the photovoltaic module 21, charging pile module 22, electric vehicle module 23, and control board via a Modbus bus. The PLC triggers alarms such as voice prompts and flashing lights based on sensor data or execution methods.

[0042] The escape route guidance system 31 uses embedded LED light strips, which are embedded along roads and walls and cover diffuser strips. The LEDs have a lifespan of more than 50,000 hours and the LED light strips meet the IP65 protection rating. The control board can illuminate different colors and directions of light according to the location of the fault, such as green to indicate a safe passage and red to indicate a prohibited area, so as to dynamically guide the evacuation route.

[0043] In this embodiment, the photovoltaic panel module 21, charging pile module 22, and electric vehicle module 23 are all connected to model 1 via magnetic interfaces, allowing for quick disassembly and replacement. The demonstration system as a whole adopts a DC 24V voltage protection circuit. The simulation unit completes the simulation within 15 minutes, ensuring that the equipment will not overheat due to continuous operation.

[0044] In this embodiment, the specific demonstration process is as follows:

[0045] 1. Install Model 1 in the demonstration area, ensuring that Model 1 is level. Fix the photovoltaic panel module 21 to one end of Model 1. Set the charging pile module 22 on the side of the photovoltaic panel module 21. Install the electric vehicle module 23 in the corresponding position of the charging pile module 22 and fix it.

[0046] 2. Install the escape route guidance system 31 by embedding LED light strips into the surface of model 1.

[0047] 3. Set a control plate on the outside of model 1, and fix the control plate to the side of model 1.

[0048] 4. With the power off, connect the DC 24V power supply to the interior of Model 1. Connect the photovoltaic panel module 21, charging pile module 22, electric vehicle module 23, control board, and other components to the power supply. All modules are connected via a Modbus bus.

[0049] 5. Check that all devices are properly wired.

[0050] 6. Demonstrate according to requirements, with demonstration effects including: automatic execution, random triggering, and manual triggering. When the automatic execution mode is running, the control panel can display the status of each module. Specifically:

[0051] In photovoltaic module 21, dust accumulation on the photovoltaic panel causes localized overheating and reduced efficiency, leading to fluctuations in the input voltage of the charging pile and eventually a fire.

[0052] In the charging pile module 22, when the photovoltaic panel module 21 catches fire, it will cause the simulated input voltage of the charging pile 22 to fluctuate. In this embodiment, the charging pile module 22 is equipped with an indicator light, which can indicate the status of the charging pile.

[0053] When the charging pile input fluctuates, the electric vehicle model 23 enters an overcharge simulation. The control board first illuminates the battery indicator light of the electric vehicle model 23, then activates the atomizer and bulging structure, triggering the LED lights to simulate a flame effect accompanied by a voice alarm. This specifically demonstrates the effect of battery bulging and smoke. After one electric vehicle model 23 simulates a fire, adjacent electric vehicle models 23 will perform the same process after a certain period of time, creating the effect of the fire spreading to nearby vehicles.

[0054] The escape route guidance system 31 can mark the road markings on the surface of Model 1, using green for safe parts and red for dangerous parts.

[0055] After the demonstration, the control board stops the operation of each device and records the operation process of each module during the demonstration. The control board can display the simulated temperature of each device during the simulated fire, achieving three-dimensional linkage of fault, phenomenon, and data.

[0056] The entire demonstration lasted no more than 15 minutes.

[0057] The demonstration can start from any step.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
