The invention discloses a fatigue fracture protection device for a vehicle gas cylinder. The fatigue fracture protection device comprises a body, wherein the body comprises an end cover I (1) close to an opening of the gas cylinder, and an end cover II (2) close to a bottom end socket of the gas cylinder; a flange I of the end cover I (1) is connected with a flange II on the end cover II (2) through a long bolt (3) and a primary buffer device (4); a sensor which is connected with a fire extinguisher control system is arranged on the primary buffer device (4); a shock absorbing material (5) is arranged between the combined surfaces of the end cover I (1) and the end cover II (2) and two ends of the gas cylinder; secondary buffer devices which are connected with a compartment are arranged on the outer sides of two ends of the body; and each secondary buffer device comprises a front buffer device (6) close to the opening of the gas cylinder and a rear buffer device (7) close to the bottom of the gas cylinder. The fatigue fracture protection device has the beneficial effects that by virtue of the primary buffer device, the secondary buffer devices, the shock absorbing material and high-tenacity connecting bots, fracture impact to the gas cylinder is effectively relieved; friction of a belt buckle is prevented; and automatic starting of the fire extinguishing system is realized.
Description
Technical field
The present invention relates to gas combustion automobile, be specifically related to a kind of fatigue fracture protective equipment of vehicle gas cylinder.
Background technique
Promote the strategy of economic development that gas combustion automobile not only meets development of the West Regions, western gas east is sent, and effectively can alleviate the dual-pressure of energy shortage and pollution of atmosphere.But, because vehicle gas cylinder security incident takes place frequently, seriously hinder the promotion and application of vehicle gas cylinder.According to both domestic and external about vehicle gas cylinder declaration of an accident, except except accidental impact or under being exposed to serious ignition condition, gas cylinder lost efficacy, all vehicle gas cylinders in use lost efficacy almost all occur in inflation or after inflation, and the gas cylinder proportion especially just having rushed gas is maximum.Find through research, gas cylinder fills repeatedly, the pressures cycle of venting makes fatigue crack grow up and by gas cylinder barrel, if form longitudinal localized cracks, leaking before breaking in the middle part of cylindrical shell, harmfulness is less, but needs to prevent naked light from contacting; If form the overall crackle of hoop, transverse breakage will occur, its harmfulness is equal to blast, because the generation of accident often has no omen, once occur to produce catastrophic consequence; In addition, owing to installing the long-term friction of bracelet, also can damage winding layer of fibers, thus reduce the intensity of gas cylinder.At present, sedan-chair vehicle gas cylinder is mainly limited to taxi trade, once gas cylinder safely problem is protected, removes the common people to the worry of gas cylinder safely, adds that national policy is fostered, and the rise of oil price, and the market demand in combustion gas car future will be doubled and redoubled.
Summary of the invention
For current vehicle gas cylinder shortcoming, the invention provides a kind of fatigue fracture protective equipment of novel vehicle gas cylinder.
To achieve these goals, the measure taked of the present invention:

Be provided with the connecting rod be connected with the eccentric wheel be hinged on support in the middle of the baffle plate of rear buffering device, eccentric wheel is provided with handle, and the stent outer near handle is provided with handle lever.
Be rectangular flange with end cap one, the flange one of end cap two integralization structure, flange two respectively.
The wall thickness of end cap one and end cap two thinnest part is not less than the twice of gas cylinder end socket average wall thickness.
First-level buffer device adopts hydraulic rod or spring.
The quantity of first-level buffer device and stay bolt is all no less than four.
The material of end cap one, end cap two and stay bolt is low carbon steel.
The material of absorbing filler is rubber.
Beneficial effect of the present invention: by adopting two-stage damping device, absorbing filler and high tenacity attachment bolt, effectively alleviates gas cylinder fracture and impacts, prevent bracelet friction, realize automatically starting suppression system.
