Description

Technical Field

[0001] This utility model relates to the field of fire fighting technology at automobile refueling and gas filling stations, and more specifically, to a telescopic insulating fire extinguishing device for a refueling and gas filling station canopy. Background Technology

[0002] Gas stations are specialized locations that provide fuel replenishment services for motor vehicles. They are mainly divided into two categories: gas stations and CNG stations. The canopy of a gas station is one of the most important architectural structures within the station. It is usually the roof above the vehicle refueling and CNG filling area and has functions such as sun and rain protection, brand identification, and safety protection. It is an iconic component of the gas station.

[0003] In the event of a fire in the canopy area, due to height restrictions, conventional fire extinguishers may struggle to effectively cover the ignition point, leading to an inability to control the initial fire in a timely manner and potentially causing wider damage. Currently, while the dry powder fire extinguishers equipped at the station can handle general fires, their limited spray distance makes it difficult to reach high-altitude fire sources, affecting emergency response efficiency. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a telescopic insulating fire extinguishing device for the canopy of a gas station, which has the advantage of extending the fire extinguishing distance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic insulating fire extinguishing device for a gas station canopy, comprising pipes and a wheeled dry powder fire extinguisher outlet pipe. The pipes consist of four sections. The top three sections are made of carbon fiber composite material, and the fourth section is made of glass fiber composite material. The four sections are connected in a nested telescopic manner. A slanted tee is threaded at the bottom of each pipe, and an insulating tube is threaded at the other end of the slanted tee. The insulating tube is made of the same material as the fourth section of pipe. A spray nozzle is threaded at the top of the first section of pipe, and a quick-connect system is provided at the input end of the slanted tee.

[0006] As a preferred technical solution of this utility model, the quick connection system includes a lever-type quick connector male with a threaded installation on the input end of the oblique tee, and the lever-type quick connector male is connected to the powder outlet pipe of the wheeled dry powder fire extinguisher through a lever-type quick connector female.

[0007] As a preferred technical solution of this utility model, a sealing ring is movably sleeved between the outer edge of the powder outlet pipe of the wheeled dry powder fire extinguisher and the bottom of the female head of the lever-type quick connector, and the sealing ring is tightly fitted with the outer edge of the powder outlet pipe of the wheeled dry powder fire extinguisher and the inner wall of the female head of the lever-type quick connector.

[0008] As a preferred technical solution of this utility model, each section of the pipe is connected to each other by a pressure-type quick connector, and the spray nozzle is the same as the powder outlet pipe of the wheeled dry powder fire extinguisher.

[0009] As a preferred technical solution of this utility model, both the male and female plugs of the lever-type quick connector are made of stainless steel, and the powder outlet pipe of the trolley-type dry powder fire extinguisher is a funnel-shaped aluminum cast nozzle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through a telescopic extension rod system, increases the vertical spray height of dry powder fire extinguishers from less than five meters to over ten meters, and extends the horizontal distance from seven meters to twelve meters, effectively covering high-altitude fire sources under the canopy of gas stations; the lightweight design of carbon fiber and glass fiber composite materials ensures flexible operation, and the nested structure enables rapid deployment and stable fixation, solving the problem of blind spots caused by the height limitation of traditional fire extinguishers, significantly shortening the response time of initial fires and reducing losses.

[0012] 2. This utility model adopts an insulating design. The fourth and fifth pipe sections and the oblique tee connection part are all made of glass fiber composite material to block current conduction and prevent operators from being electrocuted when fighting electrical fires. At the same time, the sealing design at the lower end of the oblique tee avoids waste of dry powder, and the sealing ring ensures the airtightness of the connection and improves the utilization rate of extinguishing agent. These designs not only expand the fire fighting scenarios, but also enhance operational safety and meet the protection needs of the high-risk environment of gas stations. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides a telescopic insulating fire extinguishing device for a gas station canopy, including a pipe 1 and a wheeled dry powder fire extinguisher outlet pipe 7. The pipe 1 has four sections. The top three sections of the pipe 1 are made of carbon fiber composite material, and the fourth section of the pipe 1 is made of glass fiber composite material. The four sections of the pipe 1 are connected by a nested telescopic connection. A slanted tee 3 is threaded at the bottom end of the pipe 1, and an insulating pipe 5 is threaded at the other end of the slanted tee 3. The insulating pipe 5 is made of the same material as the fourth section of the pipe 1. A spray nozzle 2 is threaded at the top end of the first section of the pipe 1, and a quick connection system 4 is provided at the input end of the slanted tee 3.

[0021] Each section of pipe 1 is connected to the others by a lever-type quick connector 6. The nozzle 2 is the same as the powder outlet pipe 7 of the wheeled dry powder fire extinguisher. Both the male and female plugs of the lever-type quick connector 41 and 42 are made of stainless steel. The powder outlet pipe 7 of the wheeled dry powder fire extinguisher is a flared aluminum cast nozzle.

[0022] Insert the powder outlet pipe 7 of the wheeled dry powder fire extinguisher into the female end of the lever-type quick connector 42, ensuring a seal using the outer edge of the nozzle and the sealing ring 43. Then connect the male end 41 of the lever-type quick connector to the bevel of the angled tee 3 to complete the quick assembly of the fire extinguisher and the telescopic rod. Unfold the nested pipe 1 and tighten it section by section using the lever-type quick connector 6. Adjust the length according to the height or distance of the fire source, with a maximum extension of over 8.5 meters. Aim at the fire source under the canopy and activate the fire extinguisher. The dry powder is delivered to the nozzle 2 through the angled tee 3 and pipe 1. The operator should hold the insulating pipe 5 and the fourth section of pipe 1 to avoid electric shock. After extinguishing the fire, loosen the quick connector, separate the fire extinguisher from the telescopic rod, retract the pipe, and seal the lower end of the angled tee for easy storage.

[0023] This device, through a telescopic extension rod system, increases the vertical spray height of dry powder fire extinguishers from less than five meters to over ten meters, and extends the horizontal distance from seven meters to twelve meters, effectively covering high-altitude fire sources under the canopy of gas stations. The lightweight design of carbon fiber and glass fiber composite materials ensures flexible operation, and the nested structure enables rapid deployment and stable fixation, solving the problem of blind spots caused by the height limitation of traditional fire extinguishers, significantly shortening the response time for initial fires and reducing losses.

[0024] The quick connection system 4 includes a lever-type quick connector male 41 threaded onto the input end of the oblique tee 3, and the lever-type quick connector male 41 is connected to the powder outlet pipe 7 of the wheeled dry powder fire extinguisher via a lever-type quick connector female 42.

[0025] The device features an insulated design, with the fourth and fifth pipe sections and the oblique tee connection using fiberglass composite materials to block current conduction and prevent electric shock to operators when fighting electrical fires. At the same time, the sealing design at the lower end of the oblique tee avoids waste of dry powder, and the sealing ring ensures the airtightness of the connection, improving the utilization rate of the extinguishing agent. These designs not only expand the fire extinguishing scenarios but also enhance operational safety, meeting the protection requirements of the high-risk environment of gas stations.

[0026] Among them, a sealing ring 43 is movably sleeved between the outer edge of the powder outlet pipe 7 of the wheeled dry powder fire extinguisher and the bottom of the lever-type quick connector female head 42. The sealing ring 43 is tightly fitted with the outer edge of the powder outlet pipe 7 of the wheeled dry powder fire extinguisher and the inner wall of the lever-type quick connector female head 42.

[0027] The sealing ring 43 improves the sealing performance between the powder outlet pipe 7 of the wheeled dry powder fire extinguisher and the female end of the lever-type quick connector 42, effectively preventing dry powder leakage and waste.

[0028] Working principle and usage process of this utility model:

[0029] Insert the powder outlet pipe 7 of the wheeled dry powder fire extinguisher into the female end of the lever-type quick connector 42, ensuring a seal using the outer edge of the nozzle and the sealing ring 43. Then connect the male end 41 of the lever-type quick connector to the bevel of the angled tee 3 to complete the quick assembly of the fire extinguisher and the telescopic rod. Unfold the nested pipe 1 and tighten it section by section using the lever-type quick connector 6. Adjust the length according to the height or distance of the fire source, with a maximum extension of over 8.5 meters. Aim at the fire source under the canopy and activate the fire extinguisher. The dry powder is delivered to the nozzle 2 through the angled tee 3 and pipe 1. The operator should hold the insulating pipe 5 and the fourth section of pipe 1 to avoid electric shock. After extinguishing the fire, loosen the quick connector, separate the fire extinguisher from the telescopic rod, retract the pipe, and seal the lower end of the angled tee for easy storage.
