[0002] Traditional municipal engineering vehicles typically have limited functionality. Water trucks are primarily used for road cleaning and greening spraying, mist cannons for dust suppression and disinfection, fire trucks for firefighting and rescue, and power supply vehicles for temporary power and emergency lighting. These single-function vehicles struggle to meet the diverse needs of common urban maintenance and emergency response scenarios, often requiring multiple vehicles with different functions to work together to address complex and changing applications. Due to the social security and public service nature of these vehicles, a certain number must be procured and deployed to serve cities, streets, and communities, resulting in high overall procurement and deployment costs. Furthermore, some municipal engineering vehicles are used infrequently, leading to wasted routine maintenance costs. They are also frequently parked, resulting in malfunctions and battery failures that prevent them from starting, increasing rescue costs and time. Delayed dispatch can also hinder rescue efforts, leading to greater losses and waste. Therefore, developing a multi-functional municipal engineering rescue vehicle is urgently needed.

[0031] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] See attached document Figure 1 With appendix Figure 2 A multi-functional municipal engineering rescue vehicle includes a vehicle chassis 1, a driver's cab, a cargo box 2, a pumping system 3, an electrical system 4, and a liquid storage device 5;

[0033] Overall structural layout:

[0034] The driver's cab is fixed to the front of the upper part of the vehicle chassis 1, providing driving power and control for the entire vehicle. The cargo box 2, serving as the carrier of the core functional modules, is fixed to the rear beam of the vehicle chassis 1, ensuring the overall structural stability and driving safety. Roller shutters are provided on the sides and rear of the cargo box 2, and these shutters are slidably connected to the frame of the cargo box 2. During transportation and storage, the roller shutters on both sides and the rear of the cargo box are closed, effectively protecting the internal components; during rescue operations, the roller shutters can be quickly opened for easy access to tools and equipment inside the cargo box. The top of the cargo box 2 is sealed and cannot be opened. Reflective warning signs are provided on both sides of the cargo box 2, significantly improving the warning effect at night or in low-visibility environments, ensuring operational safety.

[0035] The main components of the pumping system 3, the power system 4, and the liquid storage device 5 are all located inside the carriage 2, forming the core operational device for achieving multi-functional rescue operations in this invention. Specifically, the front water tank 5-1 and the rear water tank 5-2 are connected together and located at the front of the carriage 2; both are stainless steel tanks. The front water tank 5-1 and the rear water tank 5-2 are selectively supplied to the pumping system 3 via a valve pipeline switching system 5-3 (typically including a three-way valve and connecting pipelines). The first interface of this switching system 5-3 is connected to the front water tank 5-1, the second interface is connected to the rear water tank 5-2, and the third interface is connected to the inlet of the high-pressure water pump 3-1, enabling flexible selection of the two liquid sources.

[0036] Working principle of pumping system:

[0037] In one embodiment, the pumping system 3 includes a high-pressure water pump 3-1, a hose reel 3-2, a high-pressure water gun 3-3, and an atomizing spray head 3-4. The high-pressure water pump 3-1, as the core power component of the system, has its inlet connected to the liquid storage device 5 via a valve pipeline switching system 5-3. The high-pressure water pump 3-1 has two outlets: one outlet is connected to the high-pressure water gun 3-3 via a first pipeline, and the other outlet is connected to the atomizing spray head 3-4 via a second pipeline. Both the first and second pipelines are equipped with control valves to control the fluid delivery path for different operating modes. The hose reel 3-2 winds the water delivery hose of the high-pressure water gun 3-3, facilitating the storage and long-distance extension of the high-pressure water gun 3-3.

[0038] This system achieves multiple functions through the coordinated operation of its components:

[0039] Greening spraying mode: The high-pressure water pump 3-1 draws clean water from the pre-water tank 5-1 (usually for water storage), pressurizes it and delivers it to the high-pressure water gun 3-3; the operator switches the nozzle of the high-pressure water gun 3-3 to the spraying mode, and the high-pressure water flow spreads out to form a fan shape for efficient greening spraying.

[0040] Firefighting and Rescue Mode: The system switches to the post-water tank 5-2 (usually storing high-efficiency extinguishing agent, but can also store clean water if necessary) via valve pipeline switching system 5-3 as the water source. High-efficiency extinguishing agent (or clean water if necessary) is drawn by high-pressure water pump 3-1, pressurized, and delivered to high-pressure water gun 3-3. The operator switches the nozzle of high-pressure water gun 3-3 to water jet mode, concentrating the high-pressure water flow into a powerful jet to effectively suppress and extinguish early-stage fires. When the high-efficiency extinguishing agent is exhausted and continuous firefighting is needed, or when post-fire cleanup is required, the system switches back to the pre-water tank 5-1 via valve pipeline switching system 5-3.

[0041] Atomization dust suppression mode: The high-pressure water pump 3-1 draws clean water from the pre-water tank 5-1, pressurizes it and delivers it to the atomizing spray head 3-4; the high-pressure water flow forms extremely fine atomized water droplets in the atomizing spray head 3-4 and sprays them out, effectively achieving dust suppression and air purification.

[0042] Electricity and auxiliary energy systems:

[0043] In one embodiment, the power system 4 includes:

[0044] Generator set 4-1: Fixed inside the carriage 2, it is the core of the system. It converts the chemical energy of fuel into electrical energy through the work of the internal combustion engine, providing emergency power for the whole vehicle and the outside.

[0045] Electric air compressor 4-2: Located inside the carriage 2, it is powered by generator set 4-1 to generate compressed air; the compressed air can provide air source for pneumatic demolition and rescue tools through the output interface, meeting the diverse operational needs in rescue.

[0046] The right-side distribution cabinet 4-3 and the left-side distribution cabinet 4-4 are symmetrically arranged on both sides of the interior of carriage 2. Their core function is to regulate the voltage, distribute the power, and control the overall power system of the electrical energy generated by the generator, ensuring that the output electrical energy is stable and reliable (such as stable voltage and frequency), and to distribute the electrical energy to different functional electrical loads after centralized management, so as to facilitate load group control, fault isolation and flexible expansion.

[0047] Lighting warning lights 4-5: Installed on the top of the cab, they provide necessary lighting for the work site during municipal engineering rescue operations, and at the same time emit strong light warning signals to improve work safety.

[0048] The connection is as follows: the output terminals of generator set 4-1 are electrically connected to the right-side distribution cabinet 4-3 and the left-side distribution cabinet 4-4, respectively. The power output terminals of the right-side distribution cabinet 4-3 and the left-side distribution cabinet 4-4 are connected to the electric air compressor 4-2 and the lighting warning light 4-5. Furthermore, through the provided branch power supply interfaces, power support can be provided to external loads (such as emergency lighting devices, maintenance equipment, etc.). The generator set 4-1 configured in the vehicle can provide emergency power for electric devices, lighting devices, etc., while the air compressor 4-2 can provide air supply for pneumatic tools and pneumatic devices. With the demolition and rescue tools built into the vehicle compartment, combined with the aforementioned power and air supply, this vehicle can effectively assist in completing various tasks such as demolition, cutting, and repair during emergency rescue operations.

[0049] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
