Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and more specifically, to a structure of an automatic fire-extinguishing system for a fuel dispenser. Background Art

[0002] A fuel dispenser at a gas station, also known as a fuel pump, is a machine used to refuel vehicles. It is usually installed at a gas station to add fuel to vehicles such as cars and motorcycles. The fuel nozzle is the main component of the fuel dispenser and is used to inject fuel into the vehicle fuel tank. The meter is used to display the fuel quantity being refueled, so as to facilitate the operator to control the fuel quantity. The solenoid valve is responsible for controlling the on-off of the fuel pipeline to achieve the operations of refueling and stopping. The pump is used to pump fuel out of the oil tank and inject it into the vehicle fuel tank through the fuel nozzle.

[0003] During this refueling process, it is very easy due to some improper behaviors of the driver, such as abnormal starting with the vehicle not separated from the fuel nozzle, the driver smoking, etc., resulting in damage to the fuel dispenser or causing a fire at the refueling area. When a fire breaks out at the fuel dispenser, generally, a small fire extinguisher or a large push-type fire extinguisher is used for preliminary fire extinguishing, waiting for the arrival of fire rescue. And during this preliminary fire extinguishing stage, the faster the staff extinguishes the fire, the more secure the gas station can be ensured. However, for the existing gas station fire extinguishing, the staff needs to carry the fire extinguisher for fire extinguishing. At this time, a large fire has already covered the flammable leaked gasoline, making it difficult to extinguish the fire.

[0004] The Chinese utility model patent with the patent name "A Fire Extinguishing Device for a Fuel Dispenser" and the publication number CN218890086U has been publicly disclosed. This patent includes a fire extinguishing cabinet. One side of the fire extinguishing cabinet is provided with a cabinet door. Inside the fire extinguishing cabinet, there is a fire extinguishing agent storage bottle with a bottle mouth. A container valve is arranged on the bottle mouth of the fire extinguishing agent storage bottle. An electromagnetic valve is arranged on the container valve. A delivery pipe for delivering the fire extinguishing agent is arranged on the container valve. One end of the delivery pipe is provided with a spraying assembly. This device can quickly extinguish the fire, with a fast reaction speed and high fire extinguishing efficiency. The fire extinguishing agent storage bottle can provide a sufficient amount of fire extinguishing agent for fire extinguishing.

[0005] Although this device can directly extinguish the fire on the fuel dispenser without the need for the staff to carry the fire extinguisher, it still requires manual detection of the fire and manual control of the fire extinguishing. The fire extinguishing reaction time is still relatively slow, and its fire extinguishing range is fixed, and the fire extinguishing effect and applicability for different environments are not high. Summary of the Utility Model

[0006] The purpose of this application is to provide a structure of an automatic fire-extinguishing system for a fuel dispenser, which solves the technical problems of automatic fire extinguishing of the fuel dispenser and enclosed fire extinguishing for different fire extinguishing ranges.

[0014] Preferably, the top frame includes a rectangular frame. A connecting column is erected in the middle of the rectangular frame. The length direction of the connecting column is the left - right direction of the fuel dispenser. A flame sensor and a sprinkler are arranged on the connecting column, and the flame sensor and the sprinkler are vertically corresponding to the position of the fuel dispenser.

[0015] Preferably, the angle adjustment plate member includes an angle plate. The angle plate is rotatably arranged on the two side frame pipes of the rectangular frame, on both sides of the front and rear positions of the fuel dispenser. Threaded holes are penetrated through the angle plate, perpendicular to the plate surface of the angle plate. Bolts are thread - matched with the threaded holes. One end of the bolt penetrates through the angle plate and abuts against the frame pipe.

[0016] Preferably, a plurality of detection components are further arranged on the top frame. The detection components are arranged along the front and rear positions of the fuel dispenser and are in one - to - one correspondence with the positions of the sprinklers on the top frame.

[0020] The technical solution of the present application has at least the following advantages and beneficial effects:

[0021] In the present utility model, the flame sensor is used to detect the position of the fuel dispenser itself and the refueling vehicles on both sides in front of and behind the fuel dispenser. The fire response speed is fast, the detection range is wide, and the fire extinguishing range is also wide.

[0022] In the present utility model, the height of the top frame is adjusted by the telescopic vertical rod structure that can be adjusted up and down, so as to adjust the height of the flame sensor and the sprinkler head. The angles of the flame sensor and the sprinkler head can also be changed, so as to maintain an accurate measurement range interval at different heights; thus, flame detection is carried out on the main vehicles in different environments (such as a gas station next to a construction operation environment, a large construction vehicle is the main vehicle of the gas station; while in a gas station in the city, a small car is the main vehicle of the gas station), so that the device can adjust the detection range of the flame sensor and the spraying pressure of the sprinkler head accordingly.

[0023] In the present utility model, when extinguishing a fire, the flame sensor and the sprinkler head above the fuel dispenser and above the refueling positions on both sides in front of and behind the fuel dispenser are used to spray the fire extinguishing agent on the fuel dispenser and the side where the fire breaks out. Thus, a closed space is formed by the fire extinguishing agent at the fire site to isolate the external air environment, so that the flame on the gasoline can be quickly extinguished.

[0033] Embodiment

[0034] Please refer to Figures 1-5 , the present invention provides an automatic fire extinguishing system structure for the fuel dispenser 2, which is arranged in the gas station platform 1 to extinguish the sudden fire of the fuel dispenser 2 in the gas station platform 1, and includes a control box 3, a telescopic vertical rod structure 4, a top frame 5, a flame sensor 6, a sprinkler head 7, and an angle adjustment plate part 8.

[0035] Further, a control box 3 is provided on one side of the fuel dispenser 2 inside the gas station platform 1, which is responsible for storing fire extinguishing materials and manually controlling the fire extinguishing function of the entire device.

[0036] The control box 3 includes a fire extinguishing tank 302. The fire extinguishing agent is contained in the fire extinguishing tank 302 and can be ejected through a valve nozzle. One end of the fire extinguishing agent pipeline 303 is connected to the nozzle of the fire extinguishing tank 302, and the other end of the fire extinguishing agent pipeline 303 is connected to the sprinkler head 7. The sprinkler head 7 is arranged on the top frame 5 and is located above the fuel dispenser 2. When extinguishing a fire, the valve nozzle of the fire extinguishing tank 302 is opened, and the fire extinguishing agent is ejected from the sprinkler head 7 to extinguish the fire for the fuel dispenser 2 below and its surrounding area.

[0037] A telescopic vertical rod structure 4 that can be vertically displaced is provided on the control box 3. The top of the telescopic vertical rod structure 4 is provided with a top frame 5. The height of the top frame 5 can be adjusted through the telescopic vertical rod structure 4, so as to adjust the fire extinguishing range for the fuel dispenser 2 below.

[0038] A flame sensor 6 and a sprinkler head 7 are provided in the middle of the top frame 5 to detect the occurrence of a fire and spray the fire extinguishing agent to extinguish the fire for the fuel dispenser 2 body directly below it.

[0039] At both ends of the top frame 5 corresponding to the front and rear vehicle refueling positions of the fuel dispenser 2, angle adjusting plate members 8 that can rotate correspondingly are respectively provided. The rotation direction of the angle adjusting plate members 8 is along the front and rear vehicle refueling position direction of the fuel dispenser 2. Flame sensors 6 and sprinkler heads 7 are also provided on the angle adjusting plate members 8 to detect the occurrence of a fire and spray the fire extinguishing agent to extinguish the fire for the front and rear vehicle refueling positions of the fuel dispenser 2 body.

[0040] Among them, the rotation of the angle adjusting plate member 8 can change the detection angle of the flame sensor 6, so that when the top frame 5 is vertically displaced, the angle of the flame sensor 6 can be correspondingly adjusted, thereby adjusting to the optimal flame detection angle.

[0041] It should be noted that the flame sensor 6 specifically consists of a smoke detector, a temperature detector, and a flame detector in this embodiment.

[0042] Among them, the smoke detector discovers a fire by detecting the smoke particles generated during a fire.

[0043] The temperature detector discovers a fire by detecting the temperature change during a fire.

[0044] The flame detector discovers a fire by detecting the red and ultraviolet light waves emitted by the flame during a fire.

[0045] Multiple detectors are used to quickly detect and respond to the fire accidents occurring at the fuel dispenser 2, so as to increase the response speed of fire extinguishing and improve the fire extinguishing efficiency. The principles and structures of various detectors mentioned above are common knowledge mastered by those skilled in the art, so they are not specifically described in the specification.

[0046] In this embodiment, the control box 3 further includes a box body 301, a button 304, and a buzzer alarm 305.

[0047] Specifically, the box body 301 is composed of explosion-proof plate parts to prevent damage to the control box 3 and the malfunction of the device's fire extinguishing effect when the external fuel dispenser 2 catches fire or even explodes.

[0048] Inside the box body 301 are a fire extinguishing tank 302, various electrical equipment and circuits, and the explosion-proof box body 301 provides protection for them.

[0049] A buzzer alarm 305 and a switch are installed on the top of the box body 301.

[0050] The buzzer alarm 305 is connected to the signal line of the flame sensor 6. When the flame sensor 6 detects a fire, it will transmit the detection signal to the buzzer alarm 305, and the buzzer alarm 305 is triggered to emit a beeping sound, giving a timely warning of the fire to the staff, enabling the staff to react in a shorter time for fire extinguishing or evacuation.

[0051] The fire extinguishing tank 302 is composed of a gas storage tank and an electric control valve. The air pressure in the gas storage tank is relatively high, and fire extinguishing agent is stored inside. The outlet of the fire extinguishing tank 302 is closed by the electric control valve, and the electric control valve is controlled to open and close by an electric signal.

[0052] The button 304 includes an emergency stop button 304 and a start button 304.

[0053] The electric control valve of the fire extinguishing tank 302 is also connected to the signal line of the flame sensor 6. When an external flame signal is detected, it will directly control the electric control valve to open for spraying the fire extinguishing agent; and if the connection line between the flame sensor 6 and the electric control valve is damaged and the electric control valve cannot receive the electric signal to open, at this time, the start button 304 can be manually pressed to manually control the electric control valve to open for fire extinguishing.

[0054] The emergency stop button 304 is directly connected to the main circuit switch of the device. When a malfunction occurs in the device, such as continuous alarm or spraying of fire extinguishing agent under normal circumstances, at this time, the emergency stop button 304 can be manually pressed to cut off the circuit of the entire device.

[0055] In this embodiment, the telescopic vertical rod structure 4 includes a groove plate 401, a vertical pipe 402, and a fixed slot hole 403.

[0056] Specifically, a vertical chute is provided in the channel plate 401, and a vertical pipe 402 is slidably arranged in the vertical chute. The top of the vertical pipe 402 is connected to the top frame 5. The vertical pipe 402 can slide up and down in the vertical chute to control the height of the top frame 5.

[0057] A plurality of fixing slots 403 penetrate through the channel plate 401. The fixing slots 403 are vertically arranged on the channel plate 401. When the vertical position of the vertical pipe 402 is adjusted, a bolt abuts against the vertical rod through the fixing slot 403 to fix the vertical rod at the current height position.

[0058] In this embodiment, the top frame 5 includes a rectangular frame 501, a connecting column 502, a cylindrical column 503, and a cross beam 504.

[0059] Two connecting columns 502 are installed in the middle of the rectangular frame 501. The length direction of the connecting column 502 is the left - right direction of the fuel dispenser 2. Spraying heads 7 are arranged on the connecting column 502. There is a certain distance between the two connecting columns 502, and the two connecting columns 502 are connected by a cross beam 504. A flame sensor 6 is fixed on the cross beam 504. Both the flame sensor 6 and the spraying head 7 are vertically corresponding to the position of the fuel dispenser 2.

[0060] The sensing head of the flame sensor 6 on the cross beam 504 faces the fuel dispenser 2. When the fuel dispenser 2 catches fire by itself, the spraying head 7 on the connecting column 502 will start spraying the fire extinguishing agent. Among them, the spraying heads 7 of the two connecting columns 502 are respectively located at the front and rear refueling positions of the fuel dispenser 2. When spraying the fire extinguishing agent, the fire extinguishing agent will cover the fuel dispenser 2 and its front and rear refueling positions, so as to enclose the space where the entire fuel dispenser 2 is located with the fire extinguishing agent, thereby quickly cutting off the connection between the flame and the external air environment and achieving rapid fire extinguishing.

[0061] It should be noted that the vertical pipe 402 and each pipe frame in the top frame 5 are all hollow pipes. The lines and the fire extinguishing agent pipeline 303 can be arranged through the hollow pipelines of each pipe frame, which can provide a certain degree of protection for them.

[0062] In this embodiment, the angle - adjusting plate member 8 includes an angle plate 801 and a fixing screw hole 802.

[0063] Specifically, the angle plate 801 is rotatably arranged on the hollow frame pipes (the frame pipes here are circular pipes) on both sides of the rectangular frame 501, respectively located on both sides of the front and rear positions of the fuel dispenser 2. A threaded hole penetrates through the angle plate 801, perpendicular to the plate surface of the angle plate 801. A bolt is thread - matched with the threaded hole. One end of the bolt passes through the angle plate 801 and abuts against the frame pipe. When rotating the angle plate 801, loosen the bolt so that one end of the bolt does not abut against and fix the frame pipe, and then the angle plate 801 can rotate on the frame pipe.

[0064] A flame sensor 6 and a sprinkler head 7 are provided on the angle plate 801. The fire extinguishing agent pipeline 303 connected to the sprinkler head 7 passes through the angle plate 801 and the frame pipe. There is a cut groove on the frame pipe. When the sprinkler head 7 rotates following the angle plate 801, the fire extinguishing agent pipeline 303 connected to the sprinkler head 7 moves in the cut groove and will not be interfered with.

[0065] Normally, the flame sensor 6 and the sprinkler head 7 on the angle plate 801 face the outside of the fuel dispenser 2, cooperating with the detection range of the flame sensor 6 in the middle of the top frame 5 to cover the fuel dispenser 2 itself, as well as the position of the refueling vehicle at the refueling positions in front of and behind the fuel dispenser 2. When a fire breaks out in the fuel dispenser 2 or in the refueling vehicle, this device can detect the entire fire range and quickly spray the fire extinguishing agent to extinguish the fire.

[0066] When the device is matched with different gas stations, different detection ranges are adjusted according to the main refueling vehicles here. Therefore, it is necessary to adjust the height of the top frame 5 and then adjust the angle of the flame sensor 6 on the angle adjustment plate member 8 to adjust the flame detection range.

[0067] Preferably, when a fire breaks out at the refueling position on one side of the fuel dispenser 2, the sprinkler heads 7 on the angle adjustment plate member 8 on that side and the sprinkler head 7 in the middle of the top frame 5 will spray the fire extinguishing agent to cover both the fuel dispenser 2 and the refueling position outside the fuel dispenser 2 with the fire extinguishing agent, completely covering the refueling position on that side in the sealed space formed by the fire extinguishing agent to isolate the external air environment and achieve rapid fire extinguishing.

[0068] Please refer to Figure 6 , in this embodiment, a plurality of detection components 9 are further provided on the top frame 5. The detection components 9 are arranged along the front and rear positions of the fuel dispenser 2 and correspond to the positions of the sprinkler heads 7 on the top frame 5 one by one.

[0069] The detection component 9 includes a sheet metal 901, a sensor 902, and an alarm lamp 903.

[0070] Specifically, the sheet metal 901 is fixed on the rectangular frame 501. A sensor 902 is provided at the lower part of the sheet metal 901. The sensor 902 is located below the sprinkler head 7. An alarm lamp 903 is provided at the upper part of the sheet metal 901. The signal line of the sensor 902 is connected to the alarm lamp 903.

[0071] The sensor 902 is set as a laser sensor 902 for detecting whether the fire extinguishing agent is sprayed out at the sprinkler head 7. When no fire extinguishing agent is sprayed out, the sensor 902 will send an undetected signal. If the device has started the fire extinguishing program at this time, the signal of the sensor 902 will be transmitted to the alarm lamp 903, and the alarm lamp 903 will receive the signal and flash the light to remind the staff that no fire extinguishing agent is sprayed out here, so that the staff can make a timely response.

[0072] So far, the embodiments of the present utility model have been described in detail. To avoid obscuring the concept of the present utility model, some details well known in the art are not described.
