[0001] This utility model relates to the field of safety protection technology for liquefied petroleum gas containers, and in particular to a liquefied petroleum gas container. Background Technology

[0002] Liquefied petroleum gas tank containers are efficient, flexible, and safe mobile pressure vessels that perfectly combine the advantages of multimodal transport with the safety design of pressure vessels, making them an indispensable part of modern energy and chemical logistics.

[0003] The existing LPG container loading and unloading system uses high-pressure hoses to connect to the tank truck. The system's protection function cannot be fully utilized. The hoses may be damaged, leading to LPG leakage. At the same time, the container may be damaged by collisions due to bumps during transportation, which cannot effectively protect the LPG container.

[0004] Therefore, we propose a liquefied petroleum gas container to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a liquefied petroleum gas container.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A liquefied petroleum gas (LPG) container includes a container body with a connecting valve at its left end. A transmission device is mounted on the container body, comprising a mounting box fixedly connected to the left end of the container body. A baffle is fixedly connected to the left end of the container body, and a rotating shaft is rotatably connected to the front end of the baffle. The front end of the rotating shaft rotatably passes through the mounting box and extends outside the mounting box. A worm gear is sleeved on the rotating shaft, and the worm gear meshes with a worm wheel. A first threaded rod is fixedly connected to the upper end of the worm wheel, and the upper end of the first threaded rod is threadedly connected to the inner wall of the mounting box. A first bevel gear is sleeved on the first threaded rod, and the first bevel gear meshes with a transmission rod. A second bevel gear meshes with the end of the transmission rod away from the first bevel gear, and a second threaded rod is fixedly connected to the end of the second bevel gear away from the transmission rod. The end of the second threaded rod away from the second bevel gear is rotatably connected to the left end of the container body. A sliding rod is threadedly connected to the second threaded rod. A sleeve is slidably connected to the outer wall of the connecting valve, and the rear end of the sliding rod is fixedly connected to the sleeve.

[0007] Preferably, an air inflator is fixedly connected to the left end of the container body, a piston plate is slidably connected inside the air inflator, an L-shaped rod is threadedly connected to the first threaded rod, and the upper end of the L-shaped rod is fixedly connected to the piston plate.

[0008] Preferably, a protective cover is fixedly installed on the container body, a protective cavity is fixedly connected to the inner wall of the protective cover, an air supply pipe is fixedly connected to the front end of the air inflator, and the end of the air supply pipe away from the air inflator is connected to the protective cavity.

[0009] Preferably, the protective cavity is made of rubber material, meaning that the volume of the protective cavity gradually increases as air is injected, allowing the outer wall of the protective cavity to fit tightly against the container body.

[0010] Preferably, a rotating handle is fixedly connected to the end of the rotating shaft away from the mounting box, and the rotating handle is provided with anti-slip ridges.

[0011] Preferably, the two ends of the transmission rod are respectively fixedly connected with bevel gears that match the first bevel gear and the second bevel gear.

[0012] Compared with existing technologies, the advantages of this device are: When injecting liquefied petroleum gas (LPG), the operator can operate the rotating handle to drive the worm gear and worm wheel to rotate, which in turn causes the first threaded rod and the first bevel gear to rotate, driving the transmission rod and the second threaded rod to rotate. This causes the slide rod to move the sleeve forward, covering the connecting valve and the high-pressure hose, preventing damage to the high-pressure hose during LPG injection and thus preventing LPG leakage.

[0013] After the injection is complete, the staff reverses the rotation of the handle to reset the slide bar and sleeve. At this time, the L-shaped rod on the first threaded rod moves upward and drives the piston plate to move upward to compress the air in the inflation box. The air enters the protective cavity through the air supply pipe and gradually expands the protective cavity, eventually fitting tightly against the container body to prevent the container body from being damaged by collision during transportation.
