The water tank 301 is fixed on one side of the cleaning vehicle body 1. One end of the water pump 302 is connected to the water tank 301, and the other end of the water pump 302 is connected to the lower end of the water pipe 303. The nozzle 304 is arranged on the upper side of the cleaning vehicle body 1, the nozzle 304 is connected to the upper end of the water pipe 303, and a plurality of nozzles 305 are provided on the nozzle 304.

[0031] A controller 5 is fixedly connected to one side of the water tank 301, and the controller 5 is connected to the fire warning mechanism 2 and the water pump 302. In this embodiment, the nozzle 304 is horizontally arranged at the rear side and the left and right sides of the cleaning vehicle body 1, and a valve is provided at the bend of the nozzle 304. The valve can control the operation of some nozzles 305 to ensure that limited water resources are effectively used.

[0032] Although the grain depot cleaning vehicle with fire-fighting function can extinguish fires by relying on the water in the water tank 301, it is only used to extinguish preliminary fires, and the main fire extinguishing still relies on the fire hydrants in the grain depot to extinguish fires.

[0033] See also Figure 4 The fire warning mechanism 2 includes an oblong ring-shaped mounting frame 201, on which two electric sliding seats 202 are slidably connected, a smoke alarm 203 is fixedly connected to the upper surface of one electric sliding seat 202, and a camera 204 is fixedly connected to the upper surface of the other electric sliding seat 202. The signals of the smoke alarm 203 and the camera 204 are transmitted to the controller 5 by wireless means.

[0034] The camera 204 is not necessary, and can also be detected by relying on the smoke alarm 203. The camera 204 can also be replaced by a temperature sensor, and the temperature sensor and the smoke alarm 203 are fixed on an electric slide seat 202 respectively.

[0035] The upper surface of the cleaning vehicle body 1 is fixedly connected with a plurality of lifting units 205, and the telescopic end of each lifting unit 205 is fixedly connected with the bottom surface of the mounting frame 201, which can further improve the detection range of the smoke alarm 202.

A roller 208 is provided on one side of the electric sliding seat 202, and the roller 208 contacts the bottom of the limit slot 206 on one side of the mounting frame 201. A motor (not shown in the figure) is provided on one side of the electric sliding seat 202, and the motor is connected to the roller 208. The motor drives the roller 208 to rotate, thereby driving the entire electric sliding seat 202 to move on the mounting frame 201. A battery for powering the motor, the smoke alarm 203 and the camera 204 is provided in the electric sliding seat 202.

[0037] See also Figure 6-8 The cleaning brush 4 includes a fixed disk 401 and a plurality of brush filaments arranged on the circumference of the fixed disk; the brush filaments include an upper brush filament 402, a middle brush filament 403 and a lower brush filament 404, the lengths of the upper brush filament 402 and the lower brush filament 404 are the same, and the lengths of the upper brush filament 402 and the lower brush filament 404 are greater than the lengths of the middle brush filament 403.

[0038] The upper brush filaments 402 and the lower brush filaments 404 are made of carbon fiber, and the middle brush filaments 403 are made of nylon. The upper brush filaments 402 and the lower brush filaments 404 made of carbon fiber provide good rigidity, and the middle brush filaments 403 made of nylon have good toughness. The combination of the upper brush filaments 402, the middle brush filaments 403 and the lower brush filaments 404 can further reduce the bouncing of grains and the generation of dust compared to a brush made of steel wire, and reduce the dust generated during the cleaning process. Compared with a brush made of pure nylon, it has better strength, more thorough cleaning, and longer service life.

[0039] When in use, the staff drives the sweeper, or the sweeper uses unmanned driving technology to travel on the planned route, the electric sliding seat 202 continuously slides along the mounting frame 201, the smoke alarm 203 issues a smoke warning for the existing fire, and the camera 204 transmits photos of the scene in real time. When it is detected that there may be a fire, the controller 5 controls the alarm light 6 to issue a work warning. The controller 5 transmits the smoke signal transmitted by the smoke alarm 203 to the main control room, and decides whether to start the fire extinguishing device 3 according to the smoke situation.

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
