Description

Technical Field

[0001] The utility model specifically relates to a vehicle-mounted liquefied gas device with high safety. Background Art

[0002] LPG usually refers to liquefied petroleum gas, also known as propane or butane. This gas can be liquefied under appropriate pressure for use in vehicles. LPG is an alternative energy source to gasoline or diesel, which can reduce dependence on traditional fuels and reduce negative impacts on the environment.

[0003] When existing on-vehicle liquefied gas is being transported, if a major collision occurs, the gas tank will be squeezed and deformed, resulting in a reduction in the internal space, but the volume of the liquefied gas inside remains unchanged, causing the internal pressure of the gas tank to increase and the tank body to rupture, with the risk of liquefied gas leakage. Severe liquefied gas leakage will cause an explosion, and the safety is low. For this reason, we propose a highly safe on-vehicle liquefied gas device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: a highly safe vehicle-mounted liquefied gas device, comprising:

[0024] A vehicle body 1, wherein the lower surface of the vehicle body 1 is provided with moving wheels 2;

[0025] A connecting assembly 3 is detachably mounted on the vehicle body 1, and a gas storage tank 4 for storing liquefied gas is provided on the connecting assembly 3;

[0026] The gas storage tank 4 includes a gas storage cavity 401, a reserved cavity 402 and a partition 403. The partition 403 is fixed to the lower inner end of the gas storage tank 4 to separate the inner side of the gas storage tank 4 into the gas storage cavity 401 and the reserved cavity 402. When the gas storage tank 4 is squeezed and deformed by collision, the internal space is reduced, but the volume of the liquefied gas stored in the gas storage cavity 401 remains unchanged, resulting in an increase in the internal pressure of the gas storage cavity 401 and causing the gas storage tank 4 to rupture. The device can introduce the stored liquefied gas into the reserved cavity 402 to relieve the pressure inside the gas storage cavity 401. The inside of the reserved cavity 402 is preferably in a vacuum state, so as to better absorb the liquefied gas into the reserved cavity 402.

[0027] The pressure relief component is arranged at one end of the gas storage tank 4 to introduce the liquefied gas inside the gas storage chamber 401 into the reserved chamber 402 during pressure relief, so as to facilitate pressure relief to the inside of the reserved chamber 402 when the pressure inside the gas storage chamber 401 increases.

[0028] In this embodiment, preferably, a broken groove 404 is provided on the partition 403, and the broken groove 404 is annular, so that the partition 403 can be broken better through the broken groove 404, so as to achieve a better pressure relief effect when a large pressure occurs in the air storage chamber 401.

[0029] In this embodiment, preferably, the pressure relief assembly includes a connecting pipe 501 and a pressure relief valve 502. The connecting pipe 501 is fixed to one end of the gas storage tank 4 to connect the gas storage chamber 401 with the inside of the reserved chamber 402, and a pressure relief valve 502 is installed on the connecting pipe 501 to conduct the pressure inside the reserved chamber 402, so as to facilitate pressure relief to the inside of the reserved chamber 402.

[0030] In this embodiment, preferably, a discharge pipe 6 is provided at one end of the gas storage tank 4, and the discharge pipe 6 is connected to the inside of the reserved chamber 402, so as to discharge the liquefied gas inside the reserved chamber 402 to the outside after pressure relief.

[0031] In this embodiment, preferably, the connecting assembly 3 includes a connecting base 301, a support block 302 and a lifting ring 303. The connecting base 301 is fixed with a support block 302 that matches the gas tank 4. The lifting ring 303 is fixed to the edge of the upper surface of the connecting base 301, so as to facilitate lifting the gas tank 4 from the vehicle body 1 for inspection and maintenance.

[0032] In this embodiment, preferably, the connecting base 301 is rectangular, and the connecting base 301 is fixed to the vehicle body 1 by bolts, which is convenient for disassembly and maintenance, and avoids the gas tank 4 being fixed to the vehicle body 1, resulting in inconvenience in later separation and affecting the separate maintenance effect of the gas tank 4.

[0033] In this embodiment, preferably, a gas storage port 405 is provided on the gas storage tank 4 , and a sealing cover is provided on the top of the gas storage port 405 .

[0034] The working principle and use process of the utility model are as follows: during use, once an external object comes into contact with and collides with the gas storage tank 4, causing the gas storage tank 4 to be squeezed and deformed, the space inside the larger gas storage chamber 401 will be squeezed and become smaller, resulting in an increase in the pressure inside the gas storage chamber 401. At this time, the pressure relief valve 502 is turned on under a relatively high pressure, so that the liquefied gas inside the gas storage chamber 401 flows into the inside of the reserved chamber 402 through the connecting pipe 501, so as to reduce the pressure inside the gas storage chamber 401 and reduce the risk of rupture. The storage of liquefied gas through the reserved chamber 402 can also reduce the leakage of liquefied gas to the outside of the gas storage tank 4 and the impact on the surrounding environment. Furthermore, when the pressure inside the gas storage chamber 401 is extremely high, the broken groove 404 will be damaged, so that the reserved chamber 402 is directly connected to the gas storage chamber 401, so as to relieve the pressure inside the gas storage chamber 401 and improve safety.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
