Description

Technical Field

[0001] The utility model relates to the technical field of fuel dispensers, in particular to an automatic fire-extinguishing fuel dispenser. Background Art

[0002] With the development of the petrochemical industry and the sharp increase in the number of cars, gas stations are becoming increasingly important in our daily lives. However, the potential safety hazards in the refueling process cannot be ignored, especially the fire risk in the refueling area. Many refueling machine fire accidents in the past have warned us that the safety protection mechanism of traditional refueling equipment still needs to be strengthened and improved.

[0003] Most of the gas stations on the market are currently equipped with basic safety measures, such as explosion-proof devices, electrostatic release facilities, and refueling operating procedures. However, when a fire breaks out, they often rely on manual or fixed fire-fighting facilities in the station to extinguish the fire. The response speed and fire-fighting efficiency may be delayed, and the fire source cannot be extinguished immediately and effectively. This is especially true when the fire is unattended or operated at night.

[0004] Therefore, some automatic fire extinguishing refueling machines have appeared on the market, such as a new type of fully automatic intelligent refueling machine dry powder fire extinguishing device with patent number CN211611386U. When a fire occurs, the fire detector 5 simultaneously detects two fire signals, smoke and temperature, around the refueling machine and transmits them to the fire alarm controller 6. The fire alarm controller 6 issues an instruction to start the solenoid valve 22 and turn on the sound and light alarm 67 to sound an alarm according to the received fire signal. After the solenoid valve 22 is activated, the needle 221 pierces the diaphragm 216 downward, and the piston 212 moves upward until the container valve 21 is fully opened to connect the dry powder inlet 2111 and the dry powder outlet 2112, and the high-pressure gas in the dry powder storage tank 7 sends out the ultra-fine dry powder fire extinguishing agent 71. The ultra-fine dry powder fire extinguishing agent 71 is sprayed onto the refueling machine through the suction pipe 23, the container valve 21, the pipeline 3, and the nozzle 4 in sequence, realizing fully automatic intelligent fire extinguishing.

[0005] However, the nozzle on the dry powder fire extinguishing device of the refueling machine does not have the function of adjusting the angle, that is, the spraying angle of the nozzle is fixed. Therefore, it has certain limitations when spraying the fire extinguishing agent, and cannot be sprayed accurately on the fire source. In view of this technical problem, the present application makes improvements. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 3As shown, the utility model discloses an automatic fire extinguishing fuel dispenser, including a fuel dispenser body 1, on which nozzle mounting frames 21 are arranged around the top of the fuel dispenser body 1, and a plurality of nozzles 3 are fixedly mounted on the nozzle mounting frames 21, and these nozzles 3 can be connected to the fire extinguishing agent storage tank through a hose, and controlled to open by an electric control valve, and the electric control valve is detected and controlled by a fire detector. Since the fire extinguishing agent storage tank, the electric control valve, and the fire detector are all existing technologies, whether they are the existing technologies mentioned in the background technology or have been widely implemented and applied in existing fire extinguishing fuel dispensers, they will not be described in detail. Among them, the nozzle mounting frame 21 is rotatably connected to the top of the fuel dispenser body 1, and a nozzle angle adjustment mechanism for driving the nozzle mounting frame 21 to rotate is provided on the top of the fuel dispenser body 1. It should be noted that the control of the nozzle angle adjustment mechanism can be automatically controlled by the ignition point detected by the fire detector, or can be manually controlled according to the ignition point. The utility model can drive the nozzle mounting frame 21 to rotate through the nozzle angle adjustment mechanism, thereby changing the angle of the nozzle 3, so that the fire extinguishing agent sprayed from the nozzle 3 can be accurately sprayed onto the fire source, thereby better extinguishing the fire.

[0024] The specific structure of the nozzle mounting bracket 21 rotatably connected to the top of the fuel dispenser body 1 is that a driving rod 21 is fixedly connected to the middle of each nozzle mounting bracket 21, and an articulated seat 11 is fixedly connected to the top of the fuel dispenser body 1 in the middle of four sides, and the driving rod 21 is rotatably connected to the articulated seat 11. In addition, a stabilizing rod 22 is fixedly connected to both ends of each nozzle mounting bracket 21, and second articulated seats 12 corresponding to the stabilizing rod 22 are provided on four sides of the top of the fuel dispenser body 1, and the stabilizing rod 22 is rotatably connected to the second articulated seat 12. This structure enables the nozzle mounting bracket 21 to be stably rotatably set on the top of the fuel dispenser body 1.

[0025] Specifically, the nozzle angle adjustment mechanism includes a sliding push mechanism, a sliding rod 4 and a linkage rod 5. A sliding rod 4 is provided corresponding to each driving rod 21. The sliding rod 4 is slidably provided on the top of the fuel dispenser body 1. A linkage rod 5 is provided corresponding to each sliding rod 4 and the driving rod 21. The two ends of the linkage rod 5 are hinged to the sliding rod 4 and the driving rod 21 respectively. The sliding push mechanism is used to control the sliding rod 4 to move closer to or away from the corresponding driving rod 21. When the sliding rod 4 is controlled to move, the driving rod 21 can be driven to rotate through the linkage rod 5, thereby rotating the nozzle mounting bracket 21, so that the angle of the nozzle 3 changes.

[0026] Among them, a limit sleeve 13 is provided on each sliding rod 4 at the top of the fuel dispenser body 1, and the limit sleeve 13 is fixed on the top of the fuel dispenser body 1. The sliding rod 4 can only slide under the restriction of the limit sleeve 13. This structure is conducive to ensuring the stability of the sliding rod 4 when sliding.

[0027] More specifically, the sliding push mechanism includes a central cone 6 and a spring 7, wherein the spring 7 is provided on both sides of each sliding rod 4, a first spring plate 41 is fixedly connected to the sliding rod 4, a second spring plate 14 is fixedly connected to both sides of each sliding rod 4 at the top of the tanker body 1, the spring 7 is held between the first spring plate 41 and the second spring plate 14, the central cone 6 is located between all the sliding rods 4, the sliding rod 4 is in contact with the surface of the central cone 6, a mounting frame 15 is fixedly connected to the top of the tanker body 1 above the central cone 6, an electric cylinder 8 is fixedly connected to the mounting frame 15, and the electric cylinder 8 is connected to the central cone 6. The central cone 6 can be controlled to move up and down by the electric cylinder 8, and in this process, due to the action of the spring 7, the sliding rod 4 will always keep in contact with the central cone 6, so the up and down movement of the central cone 6 can make the sliding rod 4 slide horizontally.

[0028] In order to make the contact between the sliding rod 4 and the central cone 6 smoother, the sliding rod 4 includes a roller 42 that abuts against the central cone 6 .

[0029] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
