When the clamping needs to be released, the L-shaped rod, the limiting wheel, the rotating shaft, the hollow cylinder, the spiral groove, the brake block and the clamping rod are rotated to release the clamping.

[0007] According to the above technical solution, hydraulic oil is arranged inside the support rod, a slot is arranged at the bottom of the piston block, and the fixed column is slidably installed on the bottom of the inner wall of the aluminum alloy plate. When the No. 1 spring drives the fixed column to reset, because the slot is small, the reflux speed of the hydraulic oil will be slowed down, so the reset speed of the piston block will be slowed down. The slower the reset speed of the piston block, the slower the reset speed of the No. 1 spring, thereby achieving a buffering effect.

[0008] According to the above technical solution, a spiral groove is provided on the circumferential surface of the hollow cylinder, and the spiral groove is threadedly connected to the rotating shaft. The rotating shaft moves rightward through the spiral groove of the hollow cylinder, and a No. 1 torsion spring is provided between the L-shaped block and the hollow block.

The spring sheet is arranged on the circumferential surface of the fixed rod, the connecting button is fixedly installed on the left side of the protective plate, and the round rod is fixedly penetrated through the inner and outer walls of the storage rack, and the impact force is absorbed after initial shock absorption by the spring sheet.

One side of the connecting rod is rotatably installed on the inner wall of the connecting button, the sliding button is slidably installed on the circumferential surface of the round rod, and the No. 3 spring is arranged between the sliding buttons on both sides. The movement of the connecting button drives the movement of the connecting rod, and the movement of the connecting rod causes the sliding button to move forward. The movement of the sliding button will compress the No. 3 spring, and the impact force generated by the collision of the protective plate is absorbed by simultaneously compressing the No. 3 spring through the sliding buttons on both sides.

At this time, the hollow frame is released and drives the fixed end of the telescopic rod to rotate downward, and at the same time, force is applied through the counterweight block, the fixed end of the telescopic rod moves to drive the resistance rod to move, and the movement of the counterweight block causes the free end of the telescopic rod to extend.

[0012] According to the above technical solution, the supporting device also includes a counterweight, a brake button, a Y-shaped rod and a resisting rod. The counterweight is fixedly mounted on the free end of the telescopic rod, the brake button is rotatably mounted on the free end of the telescopic rod, one side of the Y-shaped rod is transmission-mounted on the inner wall of the fixed plate, the other side of the Y-shaped rod is fixedly mounted on the surface of the brake button, and the resisting rod is fixedly mounted on the fixed end of the telescopic rod.

At this time, the resisting rod loses its resistance to the disc and moves along the disc.

[0013] According to the above technical solution, the supporting device also includes a No. 5 spring, a disc, a suction cup and a hollow frame. The disc is rotatably installed on the inner wall of the brake button, the No. 5 spring is arranged between the Y-shaped rod and the disc, the suction cup is arranged on the right side of the disc, and the hollow frame is fixedly installed on the fixed end of the telescopic rod. At this time, the resisting rod loses its resistance to the disc and moves along the disc. The movement of the Y-shaped rod causes the No. 5 spring in the stretched state to contract, which drives the disc to rotate. The rotation of the disc drives the suction cup to rotate until it gradually contacts the ground, so as to achieve support for the protective plate when it is hit.

[0014] A method for using an insulation structure of a cargo hold of a specialty chemical carrier comprises the following steps: Step 1: Use stainless steel plates, calcium silicate plates, rock wool, polyurethane foam and aluminum alloy plates to construct the cabin. These materials are used to achieve the purpose of heat insulation. Chemicals are loaded on the shelf and moved in the cabin through fixed columns. When placing chemicals, they are positioned and placed through positioning blocks and clamped by clamping rods. Step 2: When the guard plate is hit, the spring sheet is used to perform preliminary shock absorption and absorb the impact force, and the connecting rod drives the sliding button to compress the No. 3 spring to absorb the impact force of the large-area impact; Step three: When the protective plate is hit, the hollow frame is freed from the restriction of the plug-in block by moving the trigger block, and then the fixed end of the telescopic rod is rotated downward in cooperation with the counterweight block. At this time, the free end of the telescopic rod is extended under the influence of gravity, and the extended free end of the telescopic rod cooperates with the disc and the No. 5 spring to make the disc gradually contact with the ground, and finally the suction cup is driven by the disc to contact with the ground, and the suction force of the suction cup is used to support the storage rack in the event that it may tilt after being hit.

[0015] The present invention provides a cargo hold insulation structure and method for a specialty chemical ship, which has the following beneficial effects: (1) The invention, through the setting of the placement device, adopts stainless steel plate, calcium silicate plate, rock wool, polyurethane foam and aluminum alloy plate to realize the structure of the cabin. The purpose of heat insulation is achieved by these materials, which can prevent the influence of temperature fluctuation on chemicals and keep them at a suitable storage temperature, thereby extending their validity period and stability. Chemicals can be placed on the shelf. By placing the chemicals on the inner wall of the positioning block, the chemicals are clamped by the clamping rod in conjunction with the No. 2 spring to prevent chemical leakage caused by the uneven ups and downs of the ship when it is traveling on the water. When it is necessary to release the clamp, the clamp is released by rotating the L-shaped rod, the limit wheel, the rotating shaft, the hollow cylinder, the spiral groove, the brake block and the clamping rod. Quickly releasing the clamp can reduce the operating time of the crew and improve work efficiency. This is particularly important in the busy loading and unloading process. The outer wall of the shelf is protected from collision by the protective plate.

[0016] (2) This invention, through the setting of the protective device, when the protective plate is hit, the protective plate slides along the fixed rod and drives the connecting button to move, and also drives the trigger block to move. At this time, the protective plate will contact the spring sheet, and the spring sheet will perform initial shock absorption and then absorb the impact force. The connecting button moves to cooperate with the connecting rod, the sliding button and the No. 3 spring to absorb the impact force generated by the impact on the protective plate. If the chemical rack is hit, the container may be damaged, causing chemical leakage. The anti-collision protection can effectively reduce the risk caused by the impact, reduce leakage incidents, and protect the environment and personnel safety.

[0017] (3) The invention, through the setting of the support device, realizes the support of the protective plate when it is hit by the trigger block in conjunction with the plug block, hollow frame, telescopic rod, counterweight block, resisting rod, brake button, Y-shaped rod, disc, No. 5 spring and suction cup to prevent the storage rack from tilting. When the support device is recovered, the fixed end of the telescopic rod is reset to cooperate with the hollow frame, plug block and No. 4 spring to complete the recovery of the support device. When the support is not needed, the support device can be retracted to save storage space and improve the use efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The purpose of thermal insulation in the cabin is achieved in the above manner. The bottom plate 10 is moved by the fixed column 11, and the movement of the bottom plate 10 drives the rack 13 to move. Chemicals can be placed on the rack 13, and by placing the chemicals on the inner wall of the positioning block 14, the outer wall of the chemicals will The inclined surface of the clamping rod 19 contacts with the clamping rod 19, so that the clamping rod 19 moves to the right and compresses the No. 2 spring 110 at the same time, and the No. 2 spring 110 is reset to drive the clamping rod 19 to clamp the chemicals to prevent chemical leakage due to the uneven ups and downs of the ship when it is traveling on the water.

At this time, the protective plate 116 will contact the spring sheet 21, and the spring sheet 21 performs preliminary shock absorption and then absorbs the impact force. The movement of the connecting button 22 drives the movement of the connecting rod 23, and the movement of the connecting rod 23 causes the sliding button 25 to move forward. The movement of the sliding button 25 compresses the No. 3 spring 26.

If the chemical rack is hit, the container may be damaged, causing chemical leakage. The anti-collision protection can effectively reduce the risk caused by the impact, reduce leakage incidents, and protect the environment and personnel safety. The movement of the trigger block 27 and the contact with the plug block 32 drive the plug block 32 to move. The plug block 32 moves and will leave the hollow frame 311. At this time, the hollow frame 311 is released and drives the fixed end of the telescopic rod 33 to rotate downward. At the same time, the counterweight block 34 is used to apply force. The fixed end of the telescopic rod 33 moves and drives the resisting rod 37 to move. The movement of the counterweight block 34 causes the free end of the telescopic rod 33 to extend. The extension of the free end of the telescopic rod 33 drives the brake button 35 to move. The movement of the brake button 35 drives the Y-shaped rod 36 to move. At this time, the resisting rod 37 loses its resistance to the disc 39 and moves along the disc 39. The movement of the Y-shaped rod 36 causes the stretched No. 5 spring 38 to contract, that is, drives the disc 39 to rotate. The rotation of the disc 39 drives the suction cup 310 to rotate until it gradually contacts the ground. The protective plate 116 is supported when it is hit to prevent the rack 13 from tilting. When the support device is recovered, the fixed end of the telescopic rod 33 is reset, and the free end of the telescopic rod 33 is reset. The suction cup 310 is reset by the fifth spring 38. The fixed end of the telescopic rod 33 moves to drive the hollow frame 311 to move. When the hollow frame 311 moves, its outer wall will contact the inclined surface of the plug block 32, so that the plug block 32 moves to the left and compresses the fourth spring. When the hollow frame 311 and the plug block 32 are in the same horizontal plane, the fourth spring drives the plug block 32 to reset. At this time, the plug block 32 will be inserted into the inner wall of the hollow frame 311. At this time, the hollow frame 311 cannot move downward, that is, the recovery of the support device is completed. When the support is not needed, the support device can be retracted to save storage space and improve the use efficiency. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principles and spirit of the present invention.
