Anti-leaking bottle carrying device

Abstract

The invention discloses an anti-leaking bottle carrying device. The anti-leaking bottle carrying device is characterized by comprising an exhaust port, a gathering groove, a detecting head, an upper sealing plate, a support plate, a tension belt, a mounting base, a frame, a lower sealing plate and a secondary beam assembly, wherein the device is provided with the lower sealing plate and the secondary beam assembly at the bottom of the frame; the frame is mounted on a vehicle chassis through the lower sealing plate and the secondary beam assembly; the support plate for supporting a gas bottle and the mounting base are arranged in the frame; the tension belt is mounted on the mounting base, and can fix the gas bottle, positioned on the mounting base, in the mounting base without shaking; the upper sealing plate is arranged at the upper end of the frame, and is tightly connected with a peripheral protecting plate to form a protective cover; the upper sealing plate at the top is provided with the gathering groove upwards projected; the exhaust port is formed in the top of the gathering groove, and can exhaust gas leaked in the protective cover; and a combustible gas detecting head is arranged in the gathering groove, and is connected with an alarm during working. The anti-leaking bottle carrying device has the advantages of simple structure, reasonable design, capability of timely discovering the gas leaking problem and improvement of the use safety.

[0002] At present, liquefied natural gas has the characteristics of large calorific value and high performance. In recent years, it has been listed as the preferred fuel by many countries. It is currently used on vehicles to load liquefied natural gas cylinders. Vehicle-mounted safety gas cylinder frames, including double-layered gas cylinders for loading gas cylinders The frame is provided with a sealing plate and a sub-beam assembly at the bottom of the double-layer frame, and the double-layer frame is installed on the chassis of the vehicle through the sealing plate and the sub-beam assembly, and a support frame for supporting the gas cylinder is arranged in the double-layer frame. A tension belt is installed on the support frame, and the tension belt can fix the gas cylinder on the support frame in the support frame without shaking. The main shortcoming of the vehicle-mounted safety gas cylinder frame of the above-mentioned structural form is that during use, the double-layer The outlet of the gas cylinder placed in the frame needs to be sealed and connected with multiple pipelines and multiple hydraulic components. In the entire double-layer frame, there are at least dozens of sealing joints for connecting various pipelines and hydraulic components. In the process of use, there will inevitably be air leakage at the sealed joints. If there is an air leakage, the leaked gas and gasified natural gas will diffuse into the atmosphere in all directions, which is a potential danger, especially when the car is running. Liquefied natural gas tends to form self-detonating air masses in the atmosphere, which may cause combustion
