[0029] The leakage prevention mechanism 3 comprises a sealing assembly and a warning assembly. The sealing assembly comprises a sealing ring 31 fixedly connected to the inner walls of the liquid discharge pipe one 21 and the liquid discharge pipe two 22. The liquid discharge pipe one 21 and the liquid discharge pipe two 22 are both provided with a sliding groove two 32. The inner bottom wall of the two sliding groove two 32 is fixedly connected with a plurality of extension rods 33. The extension rods 33 are all sleeved with a spring two 34. The extension rods 33 are fixedly connected with two extrusion plates 35 at the end away from the inner bottom wall of the corresponding sliding groove two 32. The two extrusion plates 35 extend to the outside of the corresponding sliding groove two 32 and are in sliding connection with the corresponding sliding groove two 32. The inner wall of the liquid discharge pipe one 21 is fixedly connected with a plurality of connecting blocks 36. The connecting blocks 36 are fixedly connected with a sliding rod 37 between the corresponding two connecting blocks 36. The sliding rod 37 is sleeved with a spring three 38. The sliding rod 37 is slidingly connected with a buffer plate 39. The warning assembly comprises a leakage collection groove 310 arranged at the bottom of the connecting seat 1. The bottom of the connecting seat 1 is fixedly connected with a liquid guide box 311. The inner wall of the liquid guide box 311 is fixedly connected with a liquid leakage detection plate 312. The bottom of the liquid guide box 311 is fixedly connected with a liquid leakage pipe 313. The outer wall of the liquid leakage pipe 313 is fixedly connected with a valve 314. The top of the connecting seat 1 is fixedly connected with two solar panels 315. The top of the connecting seat 1 is fixedly connected with an alarm 316. The leakage prevention mechanism 3 ensures good sealing connection between the two liquid discharge pipes, reduces the risk of liquefied natural gas leakage, ensures the stability of the pressure in the liquid discharge pipe, reduces the leakage of liquefied natural gas, and at the same time reduces the loss of energy, improves the energy utilization efficiency, and reduces the operating cost. When the internal pressure of the liquid discharge pipe changes, the spring two 34 can push the support plate by compression or expansion, so that the sealing ring 31 always maintains close contact with the connecting part to ensure that the sealing performance is not affected by pressure fluctuation, effectively preventing leakage. At the same time, the buffer plate 39 can play a buffering role to reduce the damage of instantaneous impact force to the pipeline. The elasticity of the spring 38 can further disperse and absorb the impact force to protect the integrity of the pipeline and help reduce the risk of cracks or leakage of the pipeline due to pressure surge.

[0030] One specific application of the embodiment is: loosen the bolt 28, rotate the liquid discharge pipe one 21 and the liquid discharge pipe two 22, and when the liquid discharge pipe one 21 and the liquid discharge pipe two 22 rotate, the inner wall of the connecting seat 1 exerts a pressing force on the spherical positioning bead 25, and as the liquid discharge pipe one 21 and the liquid discharge pipe two 22 rotate, the pressing force increases, thereby causing the spherical positioning bead 25 to retract into the sliding groove one 23, and when the spherical positioning bead 25 retracts into the sliding groove one 23, the spring one 24 is retracted, thereby causing the spherical positioning bead 25 to disengage from the spherical positioning groove 26, so that the liquid discharge pipe one 21 and the liquid discharge pipe two 22 can be disassembled, thereby facilitating the disassembly and installation of the liquid discharge pipe one 21 and the liquid discharge pipe two 22, so that when the liquid discharge pipe one 21 and the liquid discharge pipe two 22 malfunction, they can be easily disassembled for repair or replacement, and the interior of the liquid discharge pipe can be easily cleaned to remove accumulated impurities and deposits, thereby maintaining the smoothness and cleanliness of the pipeline and preventing the accumulation of impurities and deposits from increasing the internal pressure of the pipeline, thereby causing the liquid to be discharged.

[0031] The connection between the liquid discharge pipe one 21 and the liquid discharge pipe two 22 is sealed by the sealing ring 31 to prevent liquid leakage of the liquid natural gas, and when the two sealing rings 31 come into contact with each other, they will exert a force on each other, and under the elastic action of the spring two 34, the spring two 34 will drive the telescopic rod 33 to stretch, and when the telescopic rod 33 stretches, it will drive the pressing plate 35 to move, thereby exerting a supporting force on the corresponding sealing ring 31 through the pressing plate 35, thereby increasing the contact area between the two sealing rings 31 and further enhancing the sealing effect of the sealing ring 31 to reduce the possibility of leakage. When liquid natural gas enters the liquid discharge pipe two 22 from the liquid discharge pipe one 21, the pressure generated by the liquid natural gas in the pipeline acts on the buffer plate 39, causing the buffer plate 39 to move on the slide rod 37, and when the buffer plate 39 moves, it drives the spring three 38 to contract, thereby dispersing and buffering the impact force received by the buffer plate 39 through the spring three 38, thereby reducing the impact of the liquid natural gas on the pipeline wall, thereby reducing the risk of cracks or leaks in the pipeline due to sudden pressure changes. When there is a leak of liquid natural gas, the leaked liquid natural gas will fall into the liquid leakage detection plate 312 in the liquid guide tank 311 through the leakage collection groove 310, and when the liquid leakage detection plate 312 detects the leaked liquid natural gas, it will cause the alarm 316 to sound an alarm, and the solar panel 315 will provide continuous power to the alarm 316. Connect the leakage pipe 313 to the collection device and open the valve 314 to collect the leaked liquid natural gas for centralized treatment.
