Problems solved by technology

However, the layout, fixation, safety protection, maintenance, and space layout of CNG gas storage tanks are very difficult to load on the chassis of commercial vehicles. Other similar products often lack protection, or the protection is single, which cannot guarantee the normal operation and effective collision of gas cylinders. ;Cylinder external connection method, because the layout space of the whole vehicle is limited, when the gas cylinder side is placed on the right side of the girder, due to the running process of the vehicle, it is inevitable to be bumped and impacted by fatigue damage

Abstract

The invention discloses a semi-enclosed CNG protection device which is mounted on a vehicle frame and used for protecting a CNG cylinder and comprises fixing supports arranged at two ends of the CNG cylinder, and a protection combined plate is arranged between the fixing supports and semi-surrounds the wall of the CNG cylinder. The protection combined plate comprises a splicing plate and splicingbent plates arranged at the two ends of the splicing plate, the splicing plate half surrounds the cylindrical tank wall of the CNG cylinder tank body, and the splicing bent plates are installed between the splicing plate and the fixing supports; a bent reinforcing plate is arranged on the outer walls of the fixing supports, and a CNG outlet stop valve assembly and a CNG tail end socket screw are arranged on the bent reinforcing plate at the two ends of the CNG cylinder respectively. A novel connecting structure is adopted, the connecting function is guaranteed, effective strength is achieved,arrangement is reasonable, the process is simple, and the two sides are in bolted connection with the side edges and the bottom edge of the automobile frame. The structure is novel, and the practicability is high.

Description

technical field [0001] The invention relates to an installation protection structure of a CNG vehicle, in particular to a half-pack type CNG protection device. Background technique [0002] The CNG model is a new strategic model, which is different from the traditional fuel-driven and lithium battery electric drive. This CNG model uses natural gas as the fuel for the engine, which is consistent with the national clean energy strategy goal. It has no pollution, is safe and reliable, and is easy to operate. Features to meet the requirements of the vehicle. [0003] In order to meet the national environmental protection requirements and reduce the tail gas pollution caused by the use of commercial vehicles to the environment, from the perspective of national and social responsibility, vigorously develop models with CNG (compressed natural gas) as vehicle fuel. However, the layout, fixation, safety protection, maintenance, and space layout of CNG gas storage tanks are very diff...
