Description

Technical Field

[0001] This application relates to the field of fire trucks, and particularly relates to a multi-functional fire truck for extinguishing fires. Background Art

[0002] With the development of society, as an important piece of equipment for emergency rescue, fire trucks play a crucial role in scenarios such as fire fighting and disaster site handling. They are mainly used for extinguishing fires, providing water source support, and on-site environmental treatment, and are important infrastructure for ensuring public safety.

[0003] However, the existing fire trucks have relatively single functions and usually only have a single function of extinguishing fires or supplying water. When facing complex rescue scenarios, such as road pollution and air dust in a fire scene, it is necessary to deploy multiple vehicles with different functions to cooperate. This not only increases the dispatching cost but also may delay the best rescue opportunity due to untimely equipment switching.

[0004] The technical problem to be solved by this application is to provide a multi-functional fire truck with cleaning, fog-making, and fire extinguishing functions. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of this application is to provide a multi-functional fire truck that can achieve functions such as road cleaning, environmental fog-making and dust reduction, and multi-angle fire extinguishing, improving rescue efficiency and reducing equipment investment costs.

[0006] The technical solution adopted by this application is as follows: A multi-functional fire truck includes a vehicle body. A carriage is fixedly installed at the rear end of the vehicle body. Rolling doors and swing doors are movably installed on both sides of the carriage. A shared water tank and a shared water pump for the three functions are installed inside the carriage. The output end of the shared water tank for the three functions is connected to the input end of the shared water pump for the three functions by a water pipe; A cleaning mechanism is fixedly installed at the front end of the bottom of the vehicle body, a fog cannon is fixedly installed at the rear end of the top of the vehicle body, and a fire extinguishing mechanism is fixedly installed at the front end of the top of the vehicle body; The cleaning mechanism, the fog cannon, and the fire extinguishing mechanism are all connected to the output end of the shared water pump for the three functions by water pipes.

[0007] The shared water tank for the three functions supplies water to the cleaning mechanism, the fog cannon, and the fire extinguishing mechanism through the shared water pump for the three functions, realizing water source sharing among different functional modules. By switching the working states of different mechanisms, cleaning, fog-making, or fire extinguishing operations can be completed.

[0008] In some embodiments, the cleaning mechanism includes a water outlet block and a first nozzle. The water outlet block is fixedly installed at the front end of the bottom of the vehicle body. There are multiple first nozzles fixedly connected to the bottom of the water outlet block. The input end of the water outlet block is connected to the output end of the shared water pump for the three functions by a water pipe. By spraying water through multiple first nozzles, a large area of the road surface can be covered, achieving the effect of efficiently cleaning dust and debris on the road surface.

[0009] In some embodiments, the fog cannon includes a first mounting frame, a fog barrel, a fan, an annular water outlet pipe, and a second nozzle. There are two first mounting frames fixedly connected to the rear end of the top of the vehicle body. The fog barrel is movably installed between the two first mounting frames. The fan is fixedly installed inside the fog barrel. The annular water outlet pipe is fixedly installed inside the fog barrel. The annular water outlet pipe is located at the blowing end of the fan. There are multiple second nozzles fixedly connected to the outer wall of the annular water outlet pipe in a ring shape. The input end of the annular water outlet pipe is connected to the output end of the common water pump through a water pipe. The fan promotes air flow, drives the diffusion of the water mist sprayed by the second nozzles, and achieves the effect of large-area fog making and dust reduction, improving the air quality on site.

[0010] In some embodiments, the fire extinguishing mechanism includes a turntable, a mounting cover, and a water gun. The turntable is movably installed at the front end of the top of the vehicle body. The mounting cover is movably installed on the top of the turntable. The water gun is fixedly installed inside the mounting cover. The input end of the water gun is connected to the output end of the common water pump through a water pipe. By rotating the turntable to adjust the horizontal angle of the water gun and the mounting cover to adjust the pitching angle of the water gun, the effect of flexibly aiming at the fire source position is achieved.

[0011] In some embodiments, a worm and a worm gear are movably installed on the top of the vehicle body. The worm and the worm gear are meshed with each other. A connecting shaft is fixedly connected between the top of the worm gear and the bottom of the turntable. A first driving motor is fixedly installed on the top of the vehicle body. One end of the worm is fixedly installed at the output end of the first driving motor. The first driving motor drives the worm to rotate, and drives the turntable to rotate through the worm and worm gear transmission structure, achieving the effect of the horizontal rotation of the fire extinguishing mechanism.

[0012] In some embodiments, a second driving motor is fixedly installed at the bottom of the turntable. A lead screw is fixedly installed at the output end of the second driving motor. The lead screw movably penetrates through the turntable and extends to the top of the turntable. One end of the mounting cover away from the water gun is fixedly connected with a connecting rod. An expansion rod is slidably installed inside the connecting rod. A moving sleeve is threadedly sleeved on the outer wall of the lead screw. One end of the expansion rod away from the connecting rod is movably connected with the moving sleeve. The second driving motor drives the lead screw to rotate, and the moving sleeve moves up and down along the lead screw. The expansion rod pushes the mounting cover to swing in a pitching manner, achieving the effect of adjusting the vertical angle of the water gun.

[0013] In some embodiments, two second mounting frames are fixedly connected to the top of the turntable. The mounting cover is movably installed between the two turntables. A limiting block is fixedly connected to the outer wall of the expansion rod. A limiting groove is formed in the inner wall of the connecting rod. The limiting block is located inside the limiting groove. The limiting block and the limiting groove cooperate to limit the sliding track of the expansion rod, ensuring the stability of the mounting cover during pitching adjustment.

[0014] In some embodiments, two mounting blocks are fixedly installed at the front end of the top of the vehicle body. A plurality of rollers are movably installed inside the mounting blocks. The outer wall of the roller is in contact with the bottom of the turntable. A baffle is fixedly connected to the outer wall of the rear mounting block. The roller supports the rotation of the turntable, reducing the frictional resistance. The baffle restricts the excessive rotation of the turntable, preventing the wires of the second driving motor from being wound and damaged.

[0015] In some embodiments, a slide rail is fixedly installed at the bottom of the inner wall of the rolling shutter door. The three-way common water pump is fixedly installed on the top of the slide rail. The slide rail facilitates the installation and disassembly of the three-way common water pump, improving the convenience of maintenance.

[0016] The beneficial effects of the present application are as follows:

[0017] 1. By setting up a cleaning mechanism, when in use, after the three-way common water pump pumps water from the three-way common water tank, it conveys high-pressure water flow to the water outlet block through a water pipe and sprays it in a fan shape through a plurality of nozzles one at the bottom. When the vehicle is moving, the water flow can wash away dust, oil stains and sundries on the road surface, and cooperate with the moving track of the vehicle to achieve cleaning. It can reduce the accumulation of pollutants at the fire scene or rescue passage, avoid secondary pollution, and at the same time provide a safe passage environment for subsequent rescue vehicles.

[0018] 2. By setting up a fog cannon, when in use, the three-way common water pump conveys water to the annular water outlet pipe, and fine water mist is sprayed out through the nozzles two distributed annularly. At the same time, the fan rotates at a high speed to generate a strong air flow, pushing the water mist to spread far away, realizing cooling and smoke reduction at the fire scene and suppressing the diffusion of dust, improving the sight and breathing environment of rescue personnel, and is especially suitable for the preliminary environmental control of high-risk scenes such as chemical fires.

[0019] 3. By setting up a fire extinguishing mechanism, when in use, the first driving motor drives the worm to rotate. Through the worm and worm gear transmission structure, the turntable rotates, driving the installation cover and the water gun to adjust the direction. Then the second driving motor drives the screw rod to rotate, and the moving sleeve moves up and down along the screw rod. The telescopic rod is used to push the installation cover to swing up and down, so as to adjust the spraying angle, realizing that it is not necessary for manual climbing and adjustment, and can be remotely controlled to quickly aim at high-rise buildings, corner fire sources or large-area fire points, and cooperate with the high-pressure water flow to achieve accurate fire extinguishing, shortening the rescue time and reducing the personnel risk.
