Description

Technical Field

[0001] The invention relates to a fire-fighting technical device for self-cooling and fire-proofing of petroleum storage tanks and gas storage tanks, which is widely applicable to various cylindrical, spherical and long tank bodies such as oil storage tanks and gas storage tanks. Background Art

[0002] When all oil storage tanks and gas tanks in the world encounter fires, dozens of large fire trucks are used to put out the fires. Large fire trucks specially designed for oil storage tanks are also used. This is time-consuming, labor-intensive, and ineffective, resulting in huge losses. Summary of the invention

[0003] The present invention provides a fire-fighting automation intelligent device for fully automatic intelligent cooling and fire prevention of petroleum storage tanks and gas storage tanks, which is fast and efficient and can save time, money and time.

[0004] This technology is to install a layer of 13 water cap on the top of the oil storage tank and gas storage tank to cover the top of the tank body, and the outlet of the tank top cover is inside the water cap. When the water cap is filled with water, the top of the oil storage tank and gas storage tank will naturally cool down to close to the water temperature.

[0005] There are 1 water supply pipe, 20 water level indicators, 7 water cap openings on the top of the water cap, 9 water cap opening covers on the top of the water cap openings, which are usually opened about 40 degrees and have 24 water pipe connection openings. In the middle of the outer part of the tank body, there are 16 water waist rings designed, which are close to the outside of the tank body. The height of the water waist ring is about 40% of the height of the tank body. The distance inside the water waist ring is 10 cm to 15 cm, and water is filled inside. Keep the temperature of the tank body from rising. The 18 water pipes on the water waist ring are connected to the water body that runs through the water cap and the water waist ring.

[0006] When a fire occurs inside the tank, the sensor installed on the water cap cover will automatically instruct the external 11 motor to rotate.

[0007] When the water cap cover plate is turned on, the water cap cover plate is covered on the water cap cover plate, cutting off the external oxygen from entering the tank, the fire in the tank is extinguished naturally, and the external fire source cannot enter the tank. When the temperature of the water cap cover plate is less than 120 degrees, the motor is rotating to tighten the rope to position, and the water cap cover plate is opened about 40 degrees.

[0008] When an external fire occurs and the temperature is higher than 70 degrees, the sensor instructs the micro motor to rotate. The push rod on the micro motor forcibly pushes 21 main motor power off card to close the main motor power, turn on the main power, and the main motor starts to continue to supply water.

[0009] The water flows out from the 7-water cap and flows down to the tank body, lowering the tank body temperature and keeping the tank body temperature low. The water delivery pipe is 30-50 cm in diameter, ensuring that enough water flows to the tank body to ensure that the tank body does not heat up.

[0010] When the outside temperature is below 70 degrees, the push rod on the micro motor automatically retreats, the main motor power shut-off card 21 is reset, the micro motor stops rotating, and is controlled by the floating connection 22 to operate normally.

[0011] The water cap and water waist ring are filled with water, and the external temperature of the tank is close to the water temperature, slightly lower than the natural temperature, maintaining a normal fire prevention state. External facilities such as power lines and electromechanical equipment are wrapped with asbestos cloth for fire prevention, and the outside is protected with stainless steel pipes or steel plates to prevent sun and rain.

[0012] The fully automatic intelligent fire prevention and intelligent fire extinguishing firefighting device for oil storage and gas tanks consists of a water cap on the top of the tank body, a water waist ring surrounding the middle of the tank body, and the water cap and water waist ring are filled with water. The sensor automatically turns on the intelligent fire prevention device; when an external fire source strikes, the intelligent fire prevention device automatically starts, and a large amount of water is sprayed from the water cap mouth to the outside of the tank body to reduce the tank body temperature, and the tank body is safe and fire-proof; if abnormal combustion occurs in the tank body, the water cap mouth cover automatically closes the cover plate, seals the tank body to isolate oxygen, and extinguishes the burning fire in the tank body to ensure the safety of the oil tank and gas tank; when the external temperature is normally kept below 70, the device enters the normal fire prevention state; this technology is suitable for fire prevention and fire extinguishing of various cylindrical, spherical and long tanks such as oil tanks and gas tanks, and is widely used in intelligent fire prevention and fire extinguishing devices for several oil tanks and gas tanks or oil tanks and gas tanks in large areas.
