Technical Field

[0001] This utility model relates to a training device, and more particularly to a distributed photovoltaic real fire training device, belonging to the field of fire protection training technology. Background Technology

[0002] With the increasing global demand for clean energy and the accelerated pace of energy transition, distributed photovoltaic (PV) power generation, as an efficient, environmentally friendly, and renewable energy utilization method, has experienced rapid development. However, while distributed PV systems offer numerous advantages, they also pose significant fire safety hazards. Distributed PV systems typically consist of a large number of photovoltaic panels, inverters, cables, and other electrical equipment. During long-term operation, these devices may experience fires due to factors such as equipment aging, quality issues, improper installation, electrical faults, and lightning strikes. Due to the unique and complex nature of distributed photovoltaic fires, firefighters face many challenges and risks in actual firefighting and rescue operations that differ from traditional fires, such as working with live photovoltaic panels, firefighting operations under shading, and handling power outages of electrical equipment. Training equipment is required for these tasks.

[0003] However, traditional fire training often fails to provide realistic distributed photovoltaic fire scenarios and corresponding training equipment. Firefighters find it difficult to conduct targeted training and drills in simulated combat environments, which may lead to a lack of practical experience in actual fire fighting and rescue operations, making it difficult for them to carry out fire fighting operations skillfully and safely. Utility Model Content

[0004] The purpose of this invention is to provide a distributed photovoltaic real fire training device to solve the problems mentioned in the background art, such as the lack of real distributed photovoltaic fire scenarios and equipment in traditional fire training, the difficulty for firefighters to receive targeted training, and the inability to perform safe rescues skillfully due to insufficient experience during actual fire fighting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distributed photovoltaic live-fire training device, including a support, a support plate fixedly mounted on the top of the support, a photovoltaic panel fastened to the top of the support plate via a mounting bracket, a smart ammeter mounted on one side of the support, a fire extinguishing and light-shielding blanket mounted above the support plate, a square frame fixedly mounted on the surface of the fire extinguishing and light-shielding blanket, a box fixedly mounted at the bottom of the support plate, a rotating rod rotatably mounted on the top of the box, vertical plates fixedly mounted at both ends of the rotating rod, horizontal plates fixed to the square frame fixedly mounted at the top of the two vertical plates, a gear fixedly mounted in the middle of the rotating rod, an adjustment component for adjusting the gear below the gear, and a storage battery mounted on one side of the smart ammeter.

[0006] As a preferred technical solution of this utility model, the card holder and the support plate are fixedly connected, the square frame and the horizontal plate are fixedly connected by several bolts, and the fire extinguishing and light-shielding blanket is attached to the surface of the photovoltaic panel.

[0007] As a preferred embodiment of this utility model, a placement box is fixedly provided at the bottom of the support, and a flamethrower is placed inside the placement box.

[0008] In a preferred embodiment of this invention, the photovoltaic panel and the smart ammeter are electrically connected by a wire, a mounting base is provided below the smart ammeter, and the battery is fixedly connected to the mounting base.

[0009] As a preferred embodiment of the present invention, the adjusting component includes a rack plate, which is disposed below the gear, and the gear and the rack plate are meshed together. A limiting plate is fixedly provided on one side of the top of the rack plate.

[0010] As a preferred technical solution of this utility model, an electric telescopic column is fixedly provided on one side of the bottom of the inner wall of the box. The telescopic rod of the electric telescopic column is fixedly connected to one side of the rack plate. The electric telescopic column is electrically connected to the electric telescopic column switch on the surface of the battery through a second wire.

[0011] As a preferred embodiment of this utility model, a guide plate is fixedly provided at the bottom end of the rack plate, and a guide groove is provided at the bottom end of the inner wall of the box to guide and cooperate with the guide plate.

[0012] As a preferred embodiment of this utility model, the surface of the battery is provided with a charging port, and the charging port is electrically connected to the battery.

[0013] Compared with related technologies, the distributed photovoltaic live-fire training device provided by this utility model has the following beneficial effects: 1. The adjustable components drive the gears to rotate, which in turn rotates the lever. Combined with the vertical and horizontal plates, this allows for adjustment of the position of the fire-extinguishing shading blanket. By observing the shading and opening of the photovoltaic panels with the blanket, the reading on the smart ammeter can be monitored. This facilitates firefighter training, enabling them to clearly understand the impact of different covering operations on the photovoltaic panel's electrical state and master safe and efficient fire-fighting and rescue procedures. The fire-extinguishing shading blanket is used to cover the photovoltaic panels. Since the photovoltaic panels will not generate current when covered, but will continue to generate current when exposed to light, covering them with the blanket cuts off the light source, thus achieving a power outage and ensuring the safety of firefighters during firefighting.

[0014] 2. The device is equipped with a current detection device, which can detect and display the current status of the photovoltaic panel before and after it is covered in real time and accurately. Firefighters can observe the data displayed by the current detection device to intuitively understand the current changes of the photovoltaic panel under different conditions, gain a deeper understanding of the intrinsic relationship between shading and power outage, and thus better grasp the principle of distributed photovoltaic fire extinguishing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6This utility model provides a distributed photovoltaic real fire training device, including a support 1, a support plate 2 fixedly mounted on the top of the support 1, a photovoltaic panel 4 clamped to the top of the support plate 2 via a clamping seat 3, and a smart ammeter 5 mounted on one side of the support 1. The smart ammeter 5 is an intelligent measuring device integrating current detection, signal processing, data analysis, and display communication functions. Its core principle is to convert the current signal into a measurable electrical signal through a sensor, and then perform digital processing and intelligent algorithm analysis to achieve high-precision, multi-functional current measurement. The smart ammeter 5 can monitor the current status of the photovoltaic system, facilitating data observation by trainees. A fire extinguishing and light-shielding blanket 6 is mounted above the support plate 2. The fire extinguishing and light-shielding blanket 6 can play a role in extinguishing fires and shading light during simulated fires, improving the safety and realism of the training. It enables firefighters to clearly understand the impact of different covering operations on the energized state of the photovoltaic panel 4, thereby mastering safe and efficient fire extinguishing and rescue procedures. A square frame 7 is fixedly mounted on the surface of the fire extinguishing and light-shielding blanket 6, which provides fire extinguishing and light-shielding functions. The light blanket 6 is supported and fixed; the fire extinguishing light blanket 6 is used to cover the photovoltaic panel 4. Since the photovoltaic panel 4 will not generate current after being covered, it will continue to generate current when there is light. By covering the light blanket, the light source of the photovoltaic panel 4 is cut off, thereby achieving the power outage effect and ensuring the safety of firefighters during the fire extinguishing process; a box 8 is fixed at the bottom of the support plate 2, and a rotating rod 9 is rotatably mounted on the top of the box 8. Vertical plates 10 are fixed at both ends of the rotating rod 9. Horizontal plates 11, which are fixed to the square frame 7, are fixed at the top of the two vertical plates 10. A gear 12 is fixed in the middle of the rotating rod 9. An adjustment component 13 for adjusting the gear 12 is located below the gear 12. The adjustment component 13 can drive the gear 12 to rotate, thereby driving the rotating rod 9 to rotate simultaneously. Combined with the vertical plates 10 and the horizontal plates 11, the position of the fire extinguishing light blanket 6 can be flexibly adjusted to meet the needs of different training scenarios; a storage battery 14 is located on one side of the smart ammeter 5, which can provide power support for the device.

[0019] The adjusting assembly 13 includes a rack plate 1301, which is positioned below the gear 12. The gear 12 meshes with the rack plate 1301. A limiting plate 1302 is fixedly provided on one side of the top of the rack plate 1301. An electric telescopic column 1303 is fixedly provided on one side of the bottom of the inner wall of the housing 8. The telescopic rod of the electric telescopic column 1303 is fixedly connected to one side of the rack plate 1301. The electric telescopic column 1303 is electrically connected to the electric telescopic column switch on the surface of the battery 14 via a second wire 16. A guide plate 1304 is fixedly provided at the bottom of the rack plate 1301. A guide groove that guides and cooperates with the guide plate 1304 is opened at the bottom of the inner wall of the housing 8. Through the adjusting assembly 13, the extension and retraction of the telescopic rod of the electric telescopic column 1303 provides power for the movement of the rack plate 1301. The rack plate 1301 meshes with the gear 12, and the movement of the rack plate 1301 drives the gear 12 to rotate, thereby rotating the rotating rod 9. In conjunction with the vertical plate 10 and the horizontal plate 11, the position of the fire extinguishing light-shielding blanket 6 can be adjusted. By shading and opening the photovoltaic panel 4 with the fire extinguishing light-shielding blanket 6, the reading on the surface of the smart ammeter 5 can be observed, which facilitates fire training for firefighters. The limit plate 1302 can limit the movement range of the rack plate 1301. It is also connected to the electric telescopic column switch of the battery 14 through the second wire 16, which allows trainees to easily control the adjustment process. The guide plate 1304 at the bottom of the rack plate 1301 cooperates with the guide groove at the bottom of the inner wall of the box 8 to ensure the stability of the rack plate 1301 during movement and play a limiting and guiding role.

[0020] The photovoltaic panel 4 and the smart ammeter 5 are electrically connected via wire 15. A mounting base 17 is provided below the smart ammeter 5, and the battery 14 is fixedly connected to the mounting base 17. The electrical connection between the photovoltaic panel 4 and the smart ammeter 5 via wire 15 enables the current generated by the photovoltaic panel 4 to be accurately transmitted to the smart ammeter 5. Trainees can intuitively read the current data and clearly understand the power generation of the photovoltaic system. The mounting base 17 below the smart ammeter 5 provides a supporting position for it.

[0021] The surface of the battery 14 is provided with a charging port, which is electrically connected to the battery 14. The charging port on the surface of the battery 14 is electrically connected to the battery 14, which facilitates charging when the battery 14 is low in power, and ensures that the battery 14 can continuously provide power support to the various components of the device.

[0022] A placement box 18 is fixedly provided at the bottom of the support 1, and a flame gun 19 is placed inside the placement box 18. By placing the flame gun 19 inside the placement box 18, the flame gun 19 has a fixed storage position, which is convenient for use during training to flame the surface of the photovoltaic panel 4.

[0023] The bracket 3 is fixedly connected to the support plate 2, and the square frame 7 is fixedly connected to the horizontal plate 11 by several bolts. The fire extinguishing light-shielding blanket 6 is attached to the surface of the photovoltaic panel 4. The fixed connection between the bracket 3 and the support plate 2 ensures the stability of the bracket 3. The fixed connection between the square frame 7 and the horizontal plate 11 by several bolts ensures that the fire extinguishing light-shielding blanket 6 can be firmly connected to the horizontal plate 11, ensuring that the fire extinguishing light-shielding blanket 6 will not fall off during the adjustment process. At the same time, it is convenient to disassemble and replace the fire extinguishing light-shielding blanket 6 after use, which is convenient for the next training. The fire extinguishing light-shielding blanket 6 is attached to the surface of the photovoltaic panel 4, which can more effectively play the role of fire extinguishing and light shading when simulating fire, improving the realism of the training and the fire extinguishing and light shading effect, and ensuring the smooth progress of the training.

[0024] When using the device, place it in a suitable work location, then check the battery 14 to ensure that electrical components such as the electric telescopic column 1303 and the smart ammeter 5 are working properly. At this time, the fire extinguishing and light-shielding blanket 6 is in the initial open state (i.e., not covering the photovoltaic panel 4). The photovoltaic panel 4 generates current under sunlight, and the display screen of the smart ammeter 5 shows the current value in real time. Next, the trainee takes out the flame gun 19 from the placement box 18 (for safety, the lit flame gun 19 can be placed on the photovoltaic panel 4 using a bracket). After ignition, the flame gun 19 is used to spray fire onto the surface of the photovoltaic panel 4 to simulate a fire scene of distributed photovoltaic modules. By observing the reading on the surface of the smart ammeter 5, the trainee can understand the current situation of the photovoltaic panel 4 under the simulated fire, intuitively read the current data, and clearly understand the power generation of the photovoltaic system. Next, the trainees operate the electric telescopic column switch on the surface of the battery 14 to control the extension of the electric telescopic column 1303. This causes the rack plate 1301 to move horizontally under the constraint of the guide plate 1304 and the guide groove, driving the gear 12 to rotate. The rotating rod 9 rotates synchronously and pushes the fire extinguishing shading blanket 6 towards the photovoltaic panel 4 through the vertical plate 10 and the horizontal plate 11. As the shading blanket gradually covers the photovoltaic panel 4, the current value displayed by the smart ammeter 5 decreases linearly with the increase of the area of ​​light blocking. When the fire extinguishing shading blanket 6 completely covers the photovoltaic panel 4, the current value drops to its original value. The trainees can observe the intuitive effect of "shading off the power" and understand the core principle of cutting off the power supply to the photovoltaic panel 4 before extinguishing the fire. Then repeat the above operation, operate the electric telescopic column switch to retract the telescopic rod, the rack plate 1301 moves in the opposite direction to drive the gear 12 to rotate counterclockwise, the fire extinguishing light-shielding blanket 6 returns to the open state, the photovoltaic panel 4 receives light and generates electricity again, the smart ammeter 5 restores the initial current display, the device can repeat the above operation, allowing multiple trainees to take turns to practice, and strengthen their understanding of the relationship between different degrees of shading and current changes. After the final training, reset the fire extinguishing light-shielding blanket 6 to the open position, disassemble and replace the photovoltaic panel 4 that is locked to the bracket 3, then remove the bolts, disassemble the frame 7 and the fire extinguishing light-shielding blanket 6, and reinstall the fire extinguishing light-shielding blanket 6 using the bolts; finally, regularly add lubricating oil to the meshing parts of the gear 12 and rack plate 1301 and the mating parts of the guide plate 1304 and the guide groove to reduce friction and ensure smooth movement and rotation; check whether the telescopic rod of the electric telescopic column 1303 is stuck, and if so, find out the cause and deal with it in time; regularly check whether the wire 15 and wire 2 16 are damaged or aged, and replace them in time if they are found to prevent safety hazards such as leakage and short circuit; check whether the smart ammeter 5 is working properly, and perform regular maintenance on each equipment part.
