DETAILED DESCRIPTION

[0026] See also Figure 1-4

[0027] Embodiment 1: A chemical safety detection device comprises a chemical storage tank 1, a support base 2 is arranged at the bottom of the chemical storage tank 1, an injection port 3 is arranged at the side of the chemical storage tank 1, and a chemical safety detection component 4 for safety detection is arranged at the top of the chemical storage tank 1.

[0028] The chemical safety detection component 4 includes an air pressure connecting plug 401 inserted at the top of the chemical storage tank body 1, and a pushing piston block 402 is slidably inserted in the air pressure connecting plug 401. A resistance connecting rod 403 is vertically arranged at the top of the pushing piston block 402. The top of the resistance connecting rod 403 passes through the top of the air pressure connecting plug 401. A resistance spring 404 is sleeved on the resistance connecting rod 403. One end of the resistance spring 404 is connected to the inner wall of the air pressure connecting plug 401, and the other end of the resistance spring 404 is connected to the pushing piston block 402. The top of the resistance connecting rod 403 is provided with a top connecting block 405.

[0029] A top connecting frame 406 is provided at the top of the air pressure connecting plug 401, an alarm 407 is installed on the top connecting frame 406, a trigger switch 408 is installed at the bottom of the alarm 407, an air leakage hole 409 is opened on the side of the air pressure connecting plug 401, an air intake storage bin 410 is provided on the side of the air leakage hole 409, the air intake storage bin 410 is connected to the air leakage hole 409 through a side connecting pipe 411, the top of the air intake storage bin 410 is connected to an air pressure safety detector 412, the side of the air intake storage bin 410 is connected to an exhaust pipe 413, and a valve 414 is installed on the exhaust pipe 413.

[0030] Embodiment 2: The difference between this embodiment and embodiment 1 is that a sealing gasket is provided at the joint between the air pressure connecting plug 401 and the chemical storage tank body 1 .

[0031] This prevents the gas pressure connecting plug 401 and the chemical storage tank 1 from leaking easily after long-term use.

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that the air leakage hole 409 is located at the upper part of the pushing piston block 402 .

[0033] When the air pressure inside the chemical storage tank 1 increases, it can enter the air pressure connecting plug 401 to push the pushing piston block 402, so that after the pushing piston block 402 moves up, the high-pressure gas will enter the air intake storage bin 410 through the air leakage hole 409.

[0034] Embodiment 4: The difference between this embodiment and embodiment 1 is that the bottom ends of the air intake storage bins 410 are connected via a connecting rod.

[0035] The air intake storage bin 410 is installed more stably on the side of the air pressure connecting plug 401 .

[0036] In this embodiment, since chemical products are often stored in tanks during transportation, the air pressure in the tanks needs to be strictly tested before transportation. However, most existing chemical storage tank air pressure detection devices only perform detection before departure. During transportation, if high temperatures are encountered, the air pressure in the tank will rise sharply. If there is no corresponding detection device, the user cannot make a reasonable judgment on the air pressure status in the tank in time, which poses a major safety hazard.

[0037] In summary, in specific implementation, when the user transports the chemical materials stored in the chemical storage tank 1 in the hot summer, when the gas inside the chemical storage tank 1 is pressurized due to the hot weather, the gas with increased pressure will enter the bottom of the gas pressure connecting plug 401, and as the air pressure increases, the gas will resist the pushing piston block 402, and a resisting connecting rod 403 is provided at the top of the pushing piston block 402, and a resisting spring 404 is sleeved on the resisting connecting rod 403, and the rebound force of the resisting spring 404 can push the piston block 402 to resist elastically.

[0038] When the air pressure inside the chemical storage tank 1 continues to rise, the air pressure resistance force is greater than the rebound resistance force of the resistance spring 404, and the pushing piston block 402 will move upward in the air pressure connecting plug 401. When the resistance connecting rod 403 is pushed upward by the pushing piston block 402, the top connecting block 405 at the top of the resistance connecting rod 403 will resist the trigger switch 408 at the bottom of the alarm 407, thereby triggering the alarm 407 to provide a safety warning to the driver during transportation. As the pushing piston block 402 moves upward, the gas entering the air pressure connecting plug 401 will enter the air intake storage bin 410 through the air vent hole 409.

[0039] The air intake storage bin 410 is connected to an air pressure safety detector 412, which can perform safety detection on the air pressure in the chemical storage tank 1 in real time, thereby facilitating the user to judge the air pressure in the chemical storage tank 1 and take effective relief measures. A valve 414 is installed on the exhaust pipe 413 on the side of the air intake storage bin 410. The user can release the continuously rising air pressure gas in the chemical storage tank 1 by opening the valve 414, so as to prevent the air pressure in the chemical storage tank 1 from continuously rising and causing great harm to the tank.
