[0002] Water transportation is an important support for international trade and an important pillar of my country's economic development. It is of great significance to promote regional economic development. With the rapid development of my country's water transport container business in recent years, the number and scale of dangerous goods containers in ports and the volume of operations have continued to increase, and the safety risks faced have also continued to increase.

[0003] Dangerous goods can be solid, liquid or gas, or they can be corrosive materials or daily necessities such as perfume. Tank containers are suitable for transporting various types of dangerous goods. A square frame is set on the outside of the tank for easy stacking.

The bottom support frame 102 is fixedly connected to the protection frame 3. The protection tube 101 is fixedly connected to the bottom support frame 102. A fixing ring 104 is fixedly connected to the outside of the protection tube 101. The fixing ring 104 is fixedly connected to the bottom support frame 102. The side protection assembly is used to protect and limit the side of the tank body 1. The side protection assembly includes a protection plate 201 and an elastic limiting piece 202. The protection plate 201 is fixedly connected to the protection frame 3. The protection plate 201 is located on both sides of the tank body 1.

[0064] In order to reduce the leakage of dangerous goods in the tank body 1, a leak-proof component is also included. The leak-proof component is used to protect the discharge pipe 2 from leakage. The leak-proof component includes a protective cover 501. The protective cover 501 is fixedly connected to the outside of the discharge pipe 2. The protective cover 501 is connected to the connecting port. A sealing ring 502 is fixedly connected to the inner wall of the connecting port. The sealing ring 502 is in contact with the outer wall of the external connecting pipe. The sizes of the connecting port and the external connecting pipe are adapted. The external connecting pipe is extended from the connecting port into the interior of the protective tube 101. The external connecting pipe and the discharge pipe 2 are connected through a threaded port. The external connecting pipe and the connecting port are sealed by the sealing ring 502 to reduce the leakage of dangerous goods in the tank body 1. At the same time, the protective cover 501 and the inner wall of the protective tube 101 are tightly attached to the external connecting pipe and the discharge pipe 2 to further reduce the leakage of dangerous goods.

A locking screw hole matching the locking screw 604 is provided on the fixed plate 602, and the locking screw 604 is in contact with the protective frame 3. In order to connect two adjacent connecting plates 601, a reinforcing plate 605 is also included. The connecting plate 601 01 is threadedly connected with connecting bolts, and two through holes are provided on the reinforcement plate 605 for the connecting bolts to pass through. The fixed plate 602 and the movable plate 603 are placed on the side close to the two adjacent protective frames 3, so that the connecting plate 601 and the fixed plate 602 are close to the protective frame 3, and the locking screw 604 is tightened to drive the movable plate 603 to move, and the movable plate 603 and the protective frame 3 are tightly attached, and the protective frame 3 is clamped together with the fixed plate 602 and the connecting plate 601, and the locking screw 604 is close to the inner side of the protective frame 3, and the protective frame 3 is connected in cooperation with the fixed plate 602, the connecting plate 601 and the movable plate 603 to ensure the stability between the two adjacent protective frames 3.

Specifically, make the fixed plate 602 and the connecting plate 601 close to the protection frames 3 at the connection, turn the locking screw 604 to make the movable plate 603 close to the protection frame 3, the movable plate 603 and the fixed plate 602 clamp the two adjacent protection frames 3, and at the same time cooperate with the connecting plate 601 and the locking screw 604 to limit the protection frame 3, and connect the two adjacent protection frames 3. When stacking containers upwards, the lifting equipment aligns the upper protection frame 3 with the lower protection frame 3. The limiting rod 701 at the bottom enters the limiting hole of the upper protection frame 3 under the action of the compression spring 702 to ensure the stability of the protection frame 3. The elastic limiting piece 202, the buffer spring 303, the buffer rod 304 and the compression block 302 limit and buffer the protection tube 101. At the same time, the protection tube 101 protects the tank body 1. After transporting to the appropriate position, loosen the locking screw 604 to make the movable plate 603 away from the fixed plate 602, remove the connecting parts from the protection frame 3, and use the lifting equipment to lift the stacked containers and transport them. When the dangerous goods inside need to be discharged, open the opening and closing plate 401, insert the external connecting pipe into the interior of the protection tube 101 and connect it to the discharge pipe 2, and the sealing ring 502 and the protective cover 501 seal the connection to discharge the dangerous goods.
