[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that have properties such as toxicity, corrosion, explosion, combustion, and combustion-supporting properties, and are harmful to the human body, facilities, and the environment.

[0003] Natural gas is generally stored in gas tanks, which are then placed in warehouses specifically for hazardous chemicals. Existing hazardous chemical gas tanks are generally placed directly in warehouses. Since gas tanks are generally made of stainless steel, for coastal cities, there are a large number of sodium, magnesium and chloride ions in seawater, which can easily react electrochemically with iron and cause corrosion to stainless steel. When the paint on the surface of the gas tank is damaged, the tank body will be directly exposed to the outside, causing the tank body to be corroded by seawater moisture. Rust on the tank body can easily cause cracks, posing a risk of natural gas leakage.

[0004] Therefore, it is urgent to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, the utility model is a protective device for storing hazardous chemicals, including a base 1, a support component and a moisture-proof component. A plurality of receiving grooves 103 are provided on the inner cavity of the base 1. The number of the receiving grooves 103 corresponds to the number of the moisture-proof components. The receiving grooves can store the moisture-proof components, thereby reducing the overall volume of the device. Figure 5 A moisture-proof component is arranged in the receiving groove, and the moisture-proof component includes a connecting plate 101, a moving plate 102, a rotating block 4, a moisture-proof plate 5, a rotating shaft 6, a gear 7 and a rotating plate 8. The moving plate 102 is slidably connected in the receiving groove, that is, the moving plate 102 can slide back and forth along the receiving groove 103. The tail of the receiving groove 103 is provided with a step surface 104, and the step surface 104 is used to prevent the moving plate 102 from sliding out of the receiving groove 103. Figure 2 As shown, one end of the movable plate 102 is fixedly connected to a relatively arranged connecting plate 101, and a rotating shaft 6 passing through the connecting plate 101 is rotatably connected in the connecting plate 101. A gear 7 is fixedly connected to the surface of the rotating shaft 6, and a rotating connecting piece 403 is fixedly connected to the surface of the rotating shaft 6. One end of the rotating connecting piece 403 is fixedly connected to a rotating block 4. Multiple rotating blocks 4 are rotated into a vertical state to prevent the natural gas storage tank from tilting and falling from the base 1. A placement groove 402 is opened on one side surface of the rotating block 4, and a moisture-proof board 5 is placed in the placement groove 402. The moisture-proof board is a gypsum board, and the gypsum board has moisture-proof properties, so that the surface of the natural gas storage tank can be prevented from getting damp. At the same time, when the gypsum board is deformed after absorbing moisture for a long time, the staff can take out the gypsum board and replace it.

[0027] like Figure 3 and Figure 6As shown, a rotating groove 401 is provided at one end of the rotating block 4, and a rotating plate 8 is rotatably connected in the rotating groove 401. The rotating shaft 801 of the rotating plate 8 is passed through the rotating groove 401. The rotating block 4 and the rotating plate 8 are magnetically attracted to each other, so as to prevent the rotating block 4 from being affected by the rotation of the rotating plate 8 when the rotating block 4 rotates, that is, in the initial state, the rotating plate 8 and the moisture-proof plate 5 are respectively located on two opposite sides of the rotating block 4. One end of two rotating plates 8 is provided with a plug-in groove 802, and one end of another rotating plate 8 is fixedly connected with a plug-in column 801 plugged into the plug-in groove 802. The plug-in column 801 is plugged into the plug-in groove 802, and the rotating block 4 is fixed by the rotating plate 8, so that the rotating block 4 remains in a vertical state.

[0028] like Figure 4 As shown, a support assembly is provided at the top of the base 1, and the support assembly includes a support plate 2, a rotating ring 201, a telescopic rod 9 and a spring 10. The support plate 2 is provided above the base 1. The support plate 2 is used to place a storage tank storing natural gas, so as to prevent the bottom of the natural gas storage tank from directly contacting the ground. The bottom end of the support plate 2 is rotatably connected to the rotating ring 201, and the top of the base 1 is fixedly connected to the telescopic rod 9 fixedly connected to the rotating ring 201. The support plate 2 is rotatably connected to the rotating ring 201, so that the support plate 2 can rotate. A spring 10 is fixedly connected between the base 1 and the rotating ring 201, and the spring 10 is wound around the surface of the telescopic rod 9. A rack 3 meshing with the gear 7 is fixedly connected to the surface of the support plate 2, and the rack 3 is L-shaped. The support plate 2 drives the rack 3 to move downward and drives the gear 7, the rotating block 4 and the moisture-proof plate 5 to rotate, so as to moisture-proof the natural gas storage tank.

[0029] The utility model can prevent the surface of the natural gas storage tank from being damp, thereby preventing the natural gas storage tank from rusting and cracking, and further preventing the natural gas stored in the gas storage tank from leaking.

[0030] When the utility model is used: first, the device is placed in a warehouse storing hazardous chemicals. When natural gas needs to be stored, the staff first lifts the gas tank storing the natural gas with a crane, and lifts the natural gas tank above the support plate 2 in the device. Then the staff places the natural gas tank on the support plate 2. The natural gas tank presses down the support plate 2 by its own weight. The support plate 2 moves downward to drive multiple racks 3 to move downward. The racks 3 move downward to drive the gears 7 to rotate. The gears 7 drive the rotating shaft 6 to rotate. The rotating shaft 6 rotates and drives the rotating block 4, the gypsum board 5 and the rotating plate 8 to rotate through the rotating connector 803, so that the rotating block 4, the gypsum board 5 and the rotating plate 8 are turned from a horizontal state to a vertical state.

[0031] Then the staff rotates the multiple rotating plates 8, rotating the rotating plates 8 from a vertical state to a horizontal state, and connects and fixes the multiple rotating plates 8 through the plug-in columns 801 and the plug-in grooves 802, and at the same time limits and fixes the multiple rotating blocks 4 and the moisture-proof plates 5, so that the moisture-proof plates 5 can protect the natural gas storage tank from moisture. The above device prevents the surface of the natural gas storage tank from getting damp, thereby preventing the natural gas storage tank from rusting and cracking, and further preventing the natural gas stored in the tank from leaking.

[0032] When the device is not needed, the staff first rotates and resets the multiple rotating plates 8, and then uses a crane to take away the natural gas storage tank. At this time, the support plate 2 is reset under the action of the spring 10 and the telescopic rod 9, and drives the multiple racks 3 to reset and move upward. The upward movement of the rack 3 drives the gear 7 to rotate in the opposite direction, thereby driving the rotating shaft 6 and the rotating connecting piece 403 and the rotating block 4 to rotate and reset, and drives the moisture-proof plate 5 and the rotating plate 8 to reset, so that the rotating block 4 is turned from a vertical state to a horizontal state, and then the staff rotates the support plate 2 to separate the rack 3 from the gear 7, and then the staff pushes the rotating block 4, and pushes the rotating block 4, the gypsum board 5 and the rotating plate 8 to the accommodating groove 103 inside the base 1, as shown in FIG. Figure 7 shown.
