Description

Technical Field

[0001] This utility model relates to the field of LNG storage and distribution station safety early warning technology, and in particular to an LNG storage and distribution station safety early warning device. Background Technology

[0002] LNG (liquefied natural gas) storage and distribution stations are crucial nodes in the natural gas supply chain, undertaking important functions such as LNG storage, transshipment, and refueling. Their safe operation is directly related to the safety of the surrounding environment, personnel, and property. Due to the flammable and explosive nature of LNG, and the presence of large amounts of flammable gas within storage and distribution stations, even a small ignition source can trigger a serious safety accident. Smoking by personnel is one of the most dangerous hazards. Despite strict no-smoking regulations in the daily operation of LNG storage and distribution stations, there is still a possibility that personnel may take the risk and smoke. If a hot spark from a cigarette butt comes into contact with leaked flammable gas, it can easily ignite and explode, causing incalculable losses.

[0003] Therefore, it is necessary to design a safety early warning device for LNG storage and distribution stations that can detect when people are smoking and promptly spray water to extinguish the smoke, preventing the ignition of flammable gases by fire sources. Utility Model Content

[0004] To overcome the drawback of LNG storage and distribution stations where personnel may carelessly smoke during daily operations, and where the high-temperature sparks from cigarette butts could easily ignite or explode leaked flammable gases, causing incalculable losses, this invention provides a safety early warning device for LNG storage and distribution stations that can detect personnel smoking and promptly spray water to extinguish the smoke, preventing the ignition of flammable gases.

[0005] The technical solution of this utility model is: a safety early warning device for an LNG storage and distribution station, comprising a mobile vehicle, a temperature detector, a gas detector, a lifting platform, a rotating platform, a base, a monitoring camera, an alarm, a first motor, a first electric telescopic rod, a water spray assembly, and a drive assembly. A temperature detector is connected to the front right side of the mobile vehicle, and a gas detector is connected to the front left side of the mobile vehicle. Two first electric telescopic rods are connected inside the mobile vehicle. A lifting platform is connected between the telescopic ends of the first electric telescopic rods. A rotating platform is rotatably connected to the lifting platform. A base is connected to the upper part of the rotating platform. A first motor is connected to the left side of the base. The first motor and the first electric telescopic rods are electrically connected to a processor via a control module. A rotating shaft is provided on the output shaft of the first motor, and a monitoring camera is connected to the rotating shaft. An alarm is connected to the upper left side of the base. A water spray assembly is provided at the front of the mobile vehicle to promptly spray water to extinguish smoke when personnel are smoking. A drive assembly is provided under the lifting platform to drive the rotating platform to rotate.

[0006] Furthermore, a knob is threaded on the front left side of the mobile vehicle.

[0007] Furthermore, the water spray assembly includes a support rod, a water gun, a second electric telescopic rod, a connecting rod, a connecting block, and a hose. The support rod is connected to the front of the upper part of the mobile vehicle, and the connecting block is rotatably connected to the upper part of the support rod. The water gun is connected to the front of the connecting block. The second electric telescopic rod is connected to the inner side of the upper part of the support rod. The second electric telescopic rod and the processor are electrically connected through a control module. The connecting rod is connected to the telescopic end of the second electric telescopic rod, and the connecting rod contacts and engages with the connecting block. A hose connects the mobile vehicle and the water gun.

[0008] Furthermore, it also includes a protective cover, which is connected to the upper part of the rotating platform.

[0009] Furthermore, the protective shield is made of transparent material.

[0010] Furthermore, it also includes a drive assembly, which includes a second motor and a support frame. The support frame is connected to the lower middle part of the lifting platform, and the second motor is connected to the support frame. The second motor and the processor are electrically connected through a control module, and the output shaft of the second motor is connected to the rotating platform.

[0011] The beneficial effects are as follows: 1. When the present invention detects that someone is smoking, it activates the second electric telescopic rod, drives the connecting rod to move left and right, and pushes the connecting block to swing left and right, so that the water in the mobile vehicle is sprayed out from the water gun through the hose to extinguish the smoke. This achieves the effect of timely spraying water to extinguish the smoke when someone is smoking, and prevents the fire source from igniting flammable gas.

[0012] 2. This utility model uses a lifting platform to move upwards, adjusting the height of the surveillance camera. Then, the second motor on the support frame is started, driving the rotating platform to rotate and adjusting the horizontal angle of the surveillance camera. Subsequently, the first motor is started, driving the rotating shaft to rotate, causing the surveillance camera to rotate. This achieves the effect of conveniently adjusting the angle and height of the camera, facilitating all-round monitoring. Attached Figure Description

The mobile vehicle 1 has a threaded knob on its front left side for easy water adjustment. The temperature detector 2 is connected to the front right side of the mobile vehicle 1, and the gas detector 3 is connected to the front left side. Two first electric telescopic rods 13 are connected inside the mobile vehicle 1, with their telescopic ends connected... A lifting platform 6 is connected, and a rotating platform 7 is rotatably connected to the lifting platform 6. A protective cover 8 is connected to the upper side of the rotating platform 7. The protective cover 8 is made of transparent material. A base 9 is connected to the upper side of the rotating platform 7. A first motor 12 is connected to the left side of the base 9. The first motor 12 and the first electric telescopic rod 13 are electrically connected to the processor through a control module. A rotating shaft is provided on the output shaft of the first motor 12. A monitoring camera 10 is connected to the rotating shaft. An alarm 11 is connected to the upper left side of the base 9. A water spray assembly is provided at the front of the mobile vehicle 1. A drive assembly is provided on the lower side of the lifting platform 6.

[0021] like Figure 1 and Figure 5 As shown, the water spray assembly includes a support rod 4, a water gun 5, a second electric telescopic rod 16, a connecting rod 17, a connecting block 18, and a hose 19. The support rod 4 is connected to the upper front side of the mobile vehicle 1. The connecting block 18 is rotatably connected to the upper part of the support rod 4. The water gun 5 is connected to the front side of the connecting block 18. The second electric telescopic rod 16 is connected to the upper inner side of the support rod 4.
