Description

Technical Field

[0001] The utility model relates to a truck box body with a fire extinguishing function, belonging to the technical field of truck boxes. Background Art

[0002] Freight vehicles, generally referred to as trucks or trucks, include dump trucks, tractor trucks, off-road trucks for off-road and roadless areas, and various vehicles built for special needs. Refers to vehicles that are mainly used to transport goods, and sometimes also refers to vehicles that can tow other vehicles, belonging to the category of commercial vehicles. Generally, they can be divided into heavy and light according to the weight of the vehicle. Most trucks use diesel engines as their power source, but some light trucks use gasoline, LPG or natural gas.

[0003] In the prior art, the cargo box of a truck generally does not have an automatic fire extinguishing function. When the box accidentally catches fire, it is often impossible to extinguish the fire quickly, thereby causing greater economic losses, and even causing casualties in severe cases. Utility Model Content

[0004] The purpose of the utility model is to provide a truck box with a fire extinguishing function. A water tank and a water pump are arranged above the box, and a smoke sensor is provided in the water tank. When a fire occurs accidentally in the box, the smoke sensor can start the water pump and the solenoid valve through a single-chip microcomputer after detecting the smoke. Water can be sprayed into the box to extinguish the fire. At the same time, carbon dioxide can be used to dilute the oxygen content in the box, thereby reducing the fire and quickly extinguishing the fire, reducing economic losses, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A truck box with a fire extinguishing function comprises a box, a box door is provided on one side of the box, a baffle is provided on the upper side of the box, a water tank is connected to one side of the baffle, a water inlet pipe is provided on the upper side of the water tank, a water outlet pipe is provided on the lower side of the water tank, one end of the water outlet pipe is connected to a water pump, one end of the water pump is connected to a pressure water pipe, the bottom of the pressure water pipe extends to the interior of the box and is connected to a water collecting tank, a plurality of spray nozzles are provided below the water collecting tank, a pressure tank is provided on one side of the interior of the box, and a smoke sensor is provided on the side adjacent to the pressure tank.

[0007] Furthermore, the water inlet pipe is L-shaped, and a threaded connector is provided at one end of the water inlet pipe.

[0008] Furthermore, the water collecting tank is in an inverted trapezoidal shape, the length of the water collecting tank is the same as the internal width of the tank body, and the spray nozzles are evenly arranged on the lower surface of the water collecting tank.

[0009] Furthermore, fixed support plates are provided on both sides of the pressure tank, the pressure tank and the fixed support plates are fixedly connected to the upper inner wall of the box body, and the gas medium inside the pressure tank is carbon dioxide.

[0010] Furthermore, an air guide pipe is connected to the bottom of the pressure tank, an electromagnetic valve is connected to the air guide pipe, the bottom of the air guide pipe is connected to an air collecting plate, and the bottom of the air collecting plate is connected to an air outlet pipe.

[0011] Furthermore, a single chip microcomputer is embedded in the inner wall of the box, the output end of the smoke sensor is electrically connected to the input end of the single chip microcomputer through a wire, and the output end of the single chip microcomputer is electrically connected to the water pump and the input end of the solenoid valve through a wire.

[0012] Furthermore, the bottom of the box body is provided with drainage holes, and the drainage holes are provided with two groups and are symmetrically arranged on both sides below the box body.

[0013] The beneficial effects of the utility model are:

[0014] 1. A water tank and a water pump are arranged above the box body, and a water collecting tank is arranged inside the box body. The water collecting tank can spray water into the box body through a spray nozzle. When a fire accidentally breaks out in the box body, the smoke sensor can detect the smoke in the box body. When the single-chip microcomputer receives the information from the smoke sensor, the single-chip microcomputer can send a command to start the water pump. The water pump guides the water in the water tank into the water collecting tank through a pressure water pipe. Finally, the water in the water collecting tank is sprayed out from each spray nozzle to extinguish the fire inside the box body.

[0015] 2. By setting a pressure tank inside the box, the gas in the pressure tank is carbon dioxide. When a fire occurs in the box, the microcontroller sends a command to start the water pump and at the same time sends a command to open the solenoid valve, so that the carbon dioxide in the pressure tank can be sprayed into the box through the air guide pipe, the air collecting plate and the air outlet pipe. When the carbon dioxide enters the box, it can dilute the oxygen content in the box, thereby reducing the fire and quickly extinguishing the fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A truck box with a fire extinguishing function comprises a box 1, a box door 2 is provided on one side of the box 1, a baffle 3 is provided on the upper side of the box 1, a water tank 4 is connected to one side of the baffle 3, a water inlet pipe 5 is provided on the upper side of the water tank 4, a water outlet pipe 6 is provided on the lower side of the water tank 4, one end of the water outlet pipe 6 is connected to a water pump 7, one end of the water pump 7 is connected to a pressure water pipe 8, the bottom of the pressure water pipe 8 extends to the interior of the box 1 and is connected to a water collecting tank 9, a plurality of spray nozzles 10 are provided below the water collecting tank 9, a pressure tank 11 is provided on one side of the interior of the box 1, and a smoke sensor 12 is provided on the adjacent side of the pressure tank 11.

[0025] Specifically, the water inlet pipe 5 is L-shaped, and a threaded connector is provided at one end of the water inlet pipe 5. The water collecting tank 9 is in an inverted trapezoidal shape. The length of the water collecting tank 9 is the same as the internal width of the box body 1. The spray nozzle 10 is evenly arranged on the lower surface of the water collecting tank 9. The water in the water collecting tank 9 can be sprayed into the box body 1 through the spray nozzle 10, which is convenient for extinguishing the fire point in the box body 1.

[0026] Specifically, fixed support plates 13 are provided on both sides of the pressure tank 11, and the pressure tank 11 and the fixed support plates 13 are fixedly connected to the upper inner wall of the box body 1. The gas medium inside the pressure tank 11 is carbon dioxide, and an air guide pipe 14 is connected to the bottom of the pressure tank 11, and an electromagnetic valve 15 is connected to the air guide pipe 14. The bottom of the air guide pipe 14 is connected to the air collecting plate 16, and the bottom of the air collecting plate 16 is connected to the air outlet pipe 17. The carbon dioxide in the pressure tank 11 can dilute the oxygen content in the box body 1 after being introduced into the box body 1, thereby reducing the fire and quickly extinguishing the fire.

[0027] Specifically, a single-chip computer 18 is embedded in the inner wall of the box body 1, the output end of the smoke sensor 12 is electrically connected to the input end of the single-chip computer 18 through a wire, and the output end of the single-chip computer 18 is electrically connected to the water pump 7 and the input end of the solenoid valve 15 through a wire. The single-chip computer 18 can control the operation of the water pump 7 and the solenoid valve 15, so that the box body 1 can automatically extinguish the fire when a fire occurs in the box body 1.
