[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 In this embodiment of the present invention, an LNG storage tank valve operation box assembly includes: an operation box 1, including a box body 101; a safety airbag 2, including a storage box 201, the storage box 201 being fixedly installed on the top of the box body 101, the storage box 201 being folded inside to store the airbag 202; and a gas generator 3, the gas generator 3 being embedded in the top of the box body 101.

[0033] Specifically, the container 101 is fixedly installed at the rear of the tank truck, and the pipeline, valve and other systems are integrated and installed inside the container 101 for protection. When the rear of the tank truck collides during its operation, the gas generator 3 is triggered to quickly generate a large amount of nitrogen gas, which is filled into the airbag 202, causing the airbag 202 to inflate and pop out from the storage box 201. This completely encloses the pipeline and valve system inside the container 101, providing protection for the valve system and buffering the operation, reducing the probability of gas leakage due to pipeline rupture.

[0034] Example 1

[0035] like Figure 1 As shown, in this embodiment, a ground wire 102 is fixedly connected to the bottom of the box 101 by bolts, and the ground wire 102 is connected to the ground wire system of the tank truck; a door 104 is hinged to the two sides of the opening of the box 101 by a reinforced hinge 103, and a sealing strip is fixedly attached to all four sides of the door 104; a locking rod 105 is rotatably installed on the front surface of the door 104, and a rod latch 106 is fixedly installed on the upper and lower sides of the opening of the box 101; a handle 107 is fixedly installed in the middle of the locking rod 105; and a handle latch 108 that is engaged with the handle 107 is fixedly installed on the front surface of the door 104.

[0036] In this embodiment, sealing strips are attached to all four sides of each door 104 to ensure a sealing effect, prevent rainwater from entering, and also isolate the pipe or valve system inside the housing 101 in case of accidental leakage, providing temporary protection.

[0037] like Figures 2-3 As shown, in this embodiment, a protective groove 203 is provided at the bottom of the airbag 202.

[0038] In practice, the inflated airbag 202 is designed as a box structure to ensure that the pipes and valve system are wrapped in the protective groove 203 when it is deployed. When it expands, if it encounters a pipe connected to the tank, the airbag 202 can also wrap the pipe directly to provide protection through its own flexibility.

[0039] Example 2

[0040] Based on Embodiment 1, in order to supplement the specific method of the gas generator 3 generating gas to deploy the airbag 202, which was not mentioned in Embodiment 1.

[0041] like Figures 2-4 As shown, in this embodiment, the gas generator 3 includes: four mounting base plates 301, which are embedded in the four corners of the top of the housing 101; a power transmission branch line 302, which is embedded in the top of the housing 101; a power transmission bus 303, which is embedded in the top of the housing 101, with its lower end fixedly connected to one end of the power transmission branch line 302, and the other end of the power transmission bus 303 connected to the airbag triggering system of the tank truck; a housing 304, which is fixedly installed at the bottom of the mounting base plate 301; a filter 305, which is embedded in the interlayer of the housing 304; an igniter 306, which is embedded at the bottom of the mounting base plate 301 and fixedly connected to one end of the power transmission branch line 302; a sodium azide 307, which is housed inside the housing 304; and a combustion chamber 308, which is located in the middle of the sodium azide 307.

[0042] In practice, when the collision sensor of the tank truck senses a collision, it sends an electrical signal to the igniter 306 through the power transmission bus 303 and the power transmission branch line 302, igniting the sodium azide 307. Through the combustion reaction 2NaN3→2Na+3N2↑, a large amount of ammonia gas is generated, which inflates the airbag 202.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
