Description

Technical Field

[0001] The present application relates to the technical field of fire extinguishing devices, and in particular to an AGV charging fire prevention and extinguishing device. Background Art

[0002] AGV is the abbreviation of automatic guided vehicle, which is widely used in the warehousing and logistics industry to transport and convey items.

[0003] Currently, AGVs on the market are usually powered by lithium batteries, which have certain battery life limitations and need to be charged after reaching the battery life limit. AGVs are usually charged together, and lithium batteries may also have the risk of combustion and explosion after long-term use. Therefore, when a large number of AGVs are charged together, when an accident occurs in one AGV, it will affect the surrounding AGVs that are being charged together, which can easily lead to chain reactions.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to prevent surrounding cars from catching fire when one car catches fire, the present application provides an AGV charging fire prevention and extinguishing device.

[0006] The present application provides an AGV charging fire prevention and extinguishing device, which adopts the following technical solution:

[0007] An AGV charging fire prevention and extinguishing device comprises a base, a vertically movable fire cover and a driving assembly for driving the fire cover to move vertically, wherein the fire cover is arranged above a trolley, and a make way groove for the trolley to connect to a charging pile for charging is arranged on a side wall of the fire cover, and the driving assembly drives the fire cover to rise so that a gap is formed between the bottom of the fire cover and the ground for the trolley to enter and exit; the fire cover is lowered to cover the trolley located at the charging position.

[0008] By adopting the above technical solution, when the fireproof cover moves downward, the connection between the trolley and the charging pile will not hinder the downward movement of the fireproof cover, so that the fireproof cover can abut against the ground after moving downward.

[0009] Optionally: Several automatic fire extinguishing devices are arranged on the side of the base away from the fireproof cover, the detection end and nozzle of one automatic fire extinguishing device are arranged on the side of the base close to the vehicle, and the detection end and nozzle of another automatic fire extinguishing device are arranged on the side of the base close to the charging pile.

[0010] By adopting the above technical solution, after the car catches fire, the automatic fire extinguishing device can spray fire extinguishing materials toward the car, thereby extinguishing the fire of the car, and can also extinguish the fire of the charging pile when the charging pile catches fire.

[0011] Optionally, the driving assembly includes a driving member arranged on a base, the driving member is arranged vertically, and a free end of the driving member is connected to the fireproof cover.

[0012] By adopting the above technical solution, when the trolley catches fire, the driving member works directly to drive the fireproof cover downward.

[0013] Optionally: the driving assembly includes a driving member arranged on a base and a connecting rope connected to a free end of the driving member, the driving member is arranged horizontally, and one end of the connecting rope away from the driving member is connected to the fireproof cover.

[0014] By adopting the above technical solution, when the trolley catches fire, the driving member no longer applies an upward force to the connecting rope, so that the fireproof cover can move downward under the action of gravity, making the movement faster.

[0015] Optionally: a guide wheel is provided on the base, and one end of the connecting rope away from the driving member passes over the top of the guide wheel and is connected to the fireproof cover.

[0016] By adopting the above technical solution, when the connecting rope moves relative to the base, the connecting rope is unlikely to directly rub against the base, thereby reducing the wear of the connecting rope and the base.

[0017] Optionally: a connecting wheel is arranged on the inner wall of the fireproof cover, and the end of the connecting rope away from the driving member passes around the connecting wheel and is connected to the base.

[0018] By adopting the above technical solution, the fireproof cover is set as a movable pulley structure, so that when the driving member restricts the downward movement of the fireproof cover, the downward force applied by the fireproof cover to the driving member can be reduced, thereby reducing the load on the driving member.

[0019] Optional: An extension piece is provided on the side of the base close to the trolley, the driving piece and the guide wheel are both provided on the extension piece, the connecting wheel is provided on the inner wall of the fireproof cover away from the base, and one end of the connecting rope away from the driving piece passes around the connecting wheel and is fixed to the extension piece.

[0020] By adopting the above technical solution, an upward force is applied to the fireproof cover away from the sliding position between the fireproof cover and the base, so that the fireproof cover can remain stable when the fireproof cover remains in a suspended state.

[0021] Optionally: A fire-fighting pipe is also provided on the base, and two water inlets of the fire-fighting pipe are provided and are respectively located on both sides of the charging pile, and the water spray outlet of the fire-fighting pipe is provided below the fireproof cover and faces the charging car, and a one-way valve that conducts toward the inside of the fire-fighting pipe is provided at the water inlet of the fire-fighting pipe.

[0022] By adopting the above technical solution, in the case of re-ignition of the car, the fire of the car can be directly extinguished without opening the fireproof cover by connecting the external water pipe to the fire-fighting pipe.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a fireproof cover that can move vertically, the burning car can be covered in case of fire, so that the burning car will not affect the surrounding cars;

[0025] 2. By setting up an automatic fire extinguishing device, the fire of the burning car can be extinguished directly after it is covered. During the process of extinguishing the fire in the car, the fire extinguishing material is not likely to affect the surrounding cars. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses an AGV charging fire prevention and extinguishing device, embodiment 1, as Figure 1 and Figure 2As shown, it includes a base 1, a fireproof cover 2 that can move vertically, and a driving assembly 3 that drives the fireproof cover 2 to move vertically. In this embodiment, the fireproof cover 2 is slidably connected to the side wall of the base 1 through two vertically arranged sliding rail pairs. Other methods can also be used, such as setting a bracket on the ground, and the fireproof cover 2 is slidably connected to the bracket. The base 1 is set on the ground and is located between the trolley and the charging pile. The lower end of the side wall of the base 1 close to the protective cover is penetrated with a connection port 11. The trolley can be connected to the charging pile through the connection port 11. The side wall of the base 1 close to the charging pile is also provided with a placement groove 12. The placement groove 12 penetrates the upper and lower end surfaces of the base 1, and the charging pile is located in the placement groove 12. The fireproof cover 2 is set with a lower opening. The fireproof cover 2 can move vertically and set the trolley cover below the fireproof cover 2, so that when the trolley burns, the fireproof cover 2 can be used to separate the burning trolley from the surrounding trolleys, so that the burning trolley is not easy to affect the surrounding trolleys.

[0033] like Figure 3 As shown, since there is a connecting structure between the car and the charging pile, and the fireproof cover 2 needs to be in contact with the ground during the blocking process, a clearance groove 21 is provided on the side wall of the fireproof cover 2 close to the base 1. The clearance groove 21 penetrates the upper and lower end surfaces of the fireproof cover 2, so that the fireproof cover 2 will not be hindered in the process of moving downward, so that the fireproof cover 2 can directly cover the entire car inside.

[0034] like Figure 2 and Figure 3 As shown, two automatic fire extinguishing devices 4 are also arranged inside the base 1. The automatic fire extinguishing devices 4 are respectively arranged on both sides of the placement groove 12. In this embodiment, the automatic fire extinguishing device 4 includes a fire extinguisher, a fire extinguishing driver for driving the handle of the fire extinguisher to rotate, a control unit for controlling the operation of the fire extinguishing driver, a temperature detector 41 and a smoke detector 42 for detection. The temperature detector 41, the smoke detector 42 and the fire extinguishing driver are all electrically connected to the control unit. The fire extinguishing driver can select a linear motion power device to drive the handle of the fire extinguisher to rotate. A horizontally arranged extension piece 13 is fixed on the base 1 by bolts. The extension piece 13 is arranged in the fireproof cover 2, wherein the nozzle of the automatic fire extinguishing device 4 located on one side, the temperature detector 41 and the smoke detector 42 are all arranged below the extension piece 13, so that the fire extinguishing material in the fire extinguisher can be sprayed toward the trolley after the trolley is detected to be burning. The nozzle, temperature detector 41 and smoke detector 42 of the automatic fire extinguishing device 4 on the other side are arranged in the placement groove 21 and face the charging pile, so that the fire extinguishing material can be sprayed toward the charging pile when a combustion chamber is generated in the charging pile.

[0035] The extension 13 is also provided with a driving assembly 3 for driving the fireproof cover 2 to move vertically. The driving assembly 3 includes a driving member 31 provided on the extension 13 and a connecting rope 32 connected to the free end of the driving member 31. The connecting rope 32 is made of a steel wire rope in this embodiment. The driving member 31 is arranged horizontally and can adopt various linear motion structures. In this embodiment, an electric push cylinder is selected. The cylinder body of the electric push cylinder is fixed to the extension 13 with bolts, and the push rod of the electric push cylinder is arranged on the side away from the base 1. The driving member 31 is electrically connected to the control units on the two automatic fire extinguishing devices 4. A guide wheel 33 is installed at one end of the extension 13 away from the base 1, and a connecting wheel 34 is installed on the inner wall of the fireproof cover 2 away from the base 1. One end of the steel wire rope is fixed to the push rod of the driving member 31, and the other end of the steel wire rope passes around the upper end of the guide wheel 33 and the connecting wheel 34 and is fixed to the extension 13, so that the fireproof cover 2 can be driven to move vertically during the movement of the push rod of the electric push cylinder.

[0036] Since fire extinguishers usually spray fire extinguishing materials once, and the batteries on the trolley may reignite, a fire-fighting pipe 5 is also provided on the base 1. Two water inlets 51 of the fire-fighting pipe 5 are respectively located on the two side walls of the base 1 adjacent to the fireproof cover 2. The water outlet of the fire-fighting pipe 5 is provided below the extension 13 and toward the trolley. A one-way valve is provided at the water inlet 51 of the fire-fighting pipe 5, which is connected to the inside of the fire-fighting pipe 5. After the trolley reignites, the water pipe can be directly connected to the water inlet 51 of the fire-fighting pipe 5, so as to spray water toward the re-ignited trolley.

[0037] The implementation principle of this embodiment is: after the trolley catches fire, the smoke detector 42 and the temperature detector 41 of the automatic fire extinguishing device 4 detect smoke and temperature changes, and then the control unit receives the signal and controls the fire extinguishing driver to work, so that the fire extinguisher sprays fire extinguishing substances toward the trolley. At the same time, the control unit also controls the driving member 31 to work, so that the driving member 31 drives the connecting rope 32 to move in a direction away from the base 1, so that the fireproof cover 2 moves downward under the action of gravity and covers the trolley.

[0038] Example 2: Figure 4 As shown, the difference from Example 1 is that the driving component 3 only includes a driving member 31, and the driving member 31 is vertically arranged. The driving member 31 can directly select a linear motion mechanism. The driving member 31 is connected to the control units of the two automatic fire extinguishing devices 4. One end of the driving member 31 is connected to the extension member 13, and the free end of the driving member 31 is connected to the fireproof cover 2, thereby driving the fireproof cover 2 to move vertically. When the driving member 31 selects an electric push cylinder, the free end of the driving member 31 is the piston rod of the electric push cylinder. When the driving member 31 selects a motor-driven lead screw slider structure, the free end of the driving member 31 is a slider. In this embodiment, the driving member 31 selects a motor-driven lead screw slider structure.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
