Description

Technical Field

[0001] This invention relates to a fire truck, specifically a mini fire truck that can self-store energy and regulate temperature, and integrates multiple functions such as fire sprinkler, dust suppression, disinfection, and ground washing, belonging to the technical field of fire emergency rescue equipment. Background Technology

[0002] Currently, common fire trucks on the market include off-road fire trucks, dry powder fire trucks, and water fire trucks. These fire trucks have the advantages of strong firefighting capabilities, large fire-fighting area, and wide fire-fighting range. However, they also have disadvantages such as high investment costs, high maintenance costs, bulky nature, poor mobility and timeliness. More seriously, they cannot reach many places, making it difficult to control initial fires in a timely and effective manner. Furthermore, they require professional firefighters to operate them. To strengthen fire emergency management, this year the State Council issued the "Opinions on Strengthening Grassroots Firefighting Work" (State Council Office Document

[2026] No. 6), which clearly requires firefighting forces to be deployed to lower levels. Each township should establish an integrated emergency fire station, and villages (communities) should have portable fire-fighting emergency equipment such as mini fire trucks to strengthen the initial response to disasters. It also requires old residential areas, urban villages, and rural areas to supplement their fire-fighting equipment and water sources, emphasizing that this should be completed within two years. All of these require mobile and flexible mini fire trucks. While existing mini fire trucks have achieved their goals of being compact, flexible, and capable of navigating old streets and alleys, they still suffer from several problems: ① Limited functionality and neglected maintenance. They are often idle under normal circumstances and may never be used, even for their entire lives. Failure to refuel or recharge them in time can lead to serious consequences in emergencies. ② Weak firefighting capabilities. They carry limited water, have a small extinguishing range, and lack mobile, portable fire extinguishers or other efficient and lightweight equipment, making them ineffective at fighting fires in high-rise buildings and blind spots. ③ In cold weather, the liquid in the fire water tank and the water pump pipes are prone to freezing, easily causing damage and cracking. ④ Fire pumps use traditional gasoline engines, which are difficult to start, especially in winter, and require specialized training. They are also difficult to use immediately in emergencies, failing to meet the requirements of early detection and extinguishing small fires. In light of the current state of fire-fighting facilities and national policy requirements, as a company specializing in the production and research of fire-fighting equipment, we believe it is necessary to conduct a comprehensive and multifunctional redesign of existing mini fire trucks. Summary of the Invention

[0003] This invention proposes a multi-functional mini fire truck, equipped with an automatic energy storage and temperature regulation device, and additionally equipped with multiple throwable liquid fire extinguishers and electric backpack water fire extinguishers, improving self-maintenance and fire extinguishing capabilities; fine water mist nozzles are added to the roof and nozzles are added to the rear of the vehicle, increasing the function of post-disaster environmental remediation, expanding the scope of application, and solving the problem of traditional mini fire trucks being idle.

[0004] To achieve the above objectives, the present invention proposes the following technical solution: a multi-functional mini fire truck, comprising: a driver's cab, a cargo box, a fire piping system, and an electrical control cabinet; a fire alarm light is installed on the roof of the driver's cab, and a battery is installed inside the driver's cab; the battery provides power to the fire truck, driving the fire truck to operate; characterized in that: The vehicle compartment is equipped with a water tank, an electrical control cabinet, and a fire-fighting equipment room; The water tank is located at the front of the vehicle body, the electrical control cabinet is located at the rear of the water tank, and the spare space at the rear of the vehicle body is used as a fire-fighting equipment room; The outer top surface of the vehicle body is equipped with a solar power generation panel, and spray pipes are installed on three sides, with multiple fine water mist nozzles sequentially installed on the spray pipes; The rear bottom edge of the vehicle body is equipped with a nozzle pipe, and the nozzle pipe is equipped with multiple nozzles that spray downwards and backwards. A lifting and rotating rod is installed at the connection between the driver's cab and the cargo box, and an emergency lighting lamp is installed at the upper end of the rod. The water tank is an insulated water tank. A fire-fighting agent tank is installed inside the lid at the top of the tank. A solenoid valve is installed at the bottom of the fire-fighting agent tank to control the flow of the agent into the water tank below. The bottom of the water tank is filled with fire-fighting water. A nuclear magnetic pump is installed at the bottom of the tank. A water level display and a temperature sensor are installed inside the water tank. The external water supply selects whether to supply water to the water tank based on the value of the water level display. An inlet is set on the front side wall of the water tank and an outlet is set on the rear side wall. The external water supply supplies water to the water tank through the inlet. The nuclear magnetic pump draws water from the water tank into the outlet. A three-way solenoid control valve is installed at the outlet to control the water discharged from the outlet to enter the circulating water pipe or the fire sprinkler main pipe. The water entering the circulating water pipe returns to the water tank for internal circulation. The other end of the fire sprinkler main pipe is equipped with a three-way connection. One way is connected to the high-pressure water pipe interface, the second way is connected to the sprinkler pipe, and the third way is connected to the nozzle pipe. Each of the second and third ways is equipped with a switch valve. An intelligent control box is installed in the electrical control room; The fire equipment room is equipped with fire hooks, folding stretchers, insulated pliers, demolition tools, and a first-aid kit on one side, and a high-pressure water hose reel on the other side. On the other side of the fire equipment room, vests equipped with multiple throwable liquid fire extinguishers and multiple electric backpack water fire extinguishers are installed. The solar power panel, intelligent control box, storage battery, temperature sensor, nuclear magnetic pump, solenoid valve, three-way solenoid control valve, emergency lighting and motor in the drive device are electrically connected. The solar panels store electrical energy into a battery via an intelligent control box. The intelligent control box controls the power supply from the storage battery to the temperature sensor, nuclear magnetic pump, solenoid valve, three-way solenoid control valve, emergency lighting, and motor in the drive device; The intelligent control box controls the nuclear magnetic pump to perform internal circulation based on the value measured by the temperature sensor. The heat energy generated by the nuclear magnetic pump and the kinetic energy of the circulating water regulate the water temperature in the water tank. The high-pressure water pipe interface is equipped with a plug. When the fire sprinkler main pipe supplies water to the fine water mist nozzle or the nozzle, the plug blocks the interface. When the fire sprinkler main pipe stops supplying water to the sprinkler pipe or nozzle, the plug is opened to drain the water in the pipe connected to it. During fire extinguishing, the high-pressure water pipe reel interface is engaged with the high-pressure water pipe interface.

[0005] Furthermore, the fine water mist nozzle is positioned outward from the vehicle body, with an angle of 45º to 60º between it and the roof surface.

[0006] Preferably, 3 to 5 electric backpack water extinguishers are provided.

[0007] Preferably, there are 4 to 6 nozzles, and the angle between the nozzles and the ground is 30° to 45°.

[0008] This invention utilizes solar energy to achieve perpetual self-charging of the battery, avoiding the drawback of not being able to recharge it in a timely manner. A high-pressure nuclear magnetic pump and internal water circulation are used to regulate the water temperature within the tank, overcoming the problem of fire-fighting water freezing in low-temperature environments. Multiple fine water mist nozzles are installed at three side openings on the top of the vehicle body, and several fan-shaped nozzles are installed at the bottom edge of the rear of the vehicle body, increasing the fire truck's functions of decontamination, dust suppression, spraying, and road washing. An electrically powered backpack-type water extinguisher and a fire-fighting vest filled with multiple throwable fire extinguishers are installed at the rear of the vehicle body, greatly improving the fire-fighting capabilities of the mini fire truck.

[0009] This invention has the advantages of being lightweight and flexible, having a fast response speed, multiple functions, simple operation, and high fire extinguishing efficiency. Attached Figure Description
