[0028] Reference Figure 1-6This utility model embodiment of the online monitoring device for chemical storage tanks includes: a storage tank 1, a corrosion simulation tube 2, a liquid detection device 4, and a pressure regulating device 9. The side wall of the storage tank 1 is fixedly connected to the outer wall of the corrosion simulation tube 2. A flange 3 is fixedly connected to the right end of the corrosion simulation tube 2. The liquid detection device 4 is fixedly connected to the right surface of the flange 3 for monitoring whether liquid flows in. A float ball 25 is installed inside the liquid detection device 4 to drive the switch shaft 26 to move together. The switch shaft 26 is fixedly connected to the upper end of the float ball 25 as a switch for the alarm 6. It can push the metal spring 31 to connect the disconnected circuit in the detection circuit 5. A fixing plate 27 is fixedly connected to the inner side wall of the liquid detection device 4 so that the switch shaft 26 can only move up and down. The detection circuit 5 is fixedly connected to the upper end of the liquid detection device 4. It is normally in the disconnected state. When it is connected, the alarm 6 works. The alarm 6 is fixedly connected to the upper end of the detection circuit 5. When liquid enters, it will sound an alarm to remind relevant personnel.

[0029] A tank cover 8 is fixedly connected to the upper end of the storage tank 1. A pressure regulating device 9 is fixedly connected to the upper surface of the tank cover 8 to regulate and maintain the air pressure inside and outside the storage tank 1. A baffle 10 is fixedly connected to the left side wall of the pressure regulating device 9 to prevent rainwater or impurities from entering the first breather valve 16. A second breather valve 11 is fixedly connected to the right side wall of the pressure regulating device 9. When the air pressure inside the storage tank 1 is lower than the external air pressure to a certain value, the second breather valve 11 operates. A valve disc 22 is slidably connected to the inner wall of the second breather valve 11. A second spring 23 is fixedly connected to the upper surface of the second breather valve 22. When the external air pressure of the storage tank 1 is greater than the internal air pressure and exceeds a certain value, the second breather valve 22 will be pushed open by the external air pressure. Subsequently, the internal air pressure will increase. After reaching a certain value, the second breather valve 22 will close due to the elastic force of the second spring 23. A second breather hole 20 is opened on the left side wall of the second breather valve 11. The inner surface of the pressure regulating device 9 is fixedly connected to the second breather valve 11. An electric telescopic rod 15 is connected to push the valve disc 18. A breather valve 16 is fixedly connected to the inner surface of the air pressure regulating device 9. When the air pressure inside the storage tank 1 is greater than the external air pressure to a certain value, the breather valve 16 works. The valve disc 18 is slidably connected to the inner wall of the breather valve 16. A spring 19 is fixedly connected to the upper surface of the valve disc 18. When the air pressure inside the storage tank 1 is greater than the external air pressure and exceeds a certain value, the valve disc 18 will be pushed open by the internal air pressure. Subsequently, the internal air pressure will decrease. After reaching a certain value, the valve disc 18 will close due to the elastic force of the spring 19. A breather hole 17 is opened on the left side wall of the breather valve 16. An integrated sensor 12 is fixedly connected to the lower surface of the tank cover 8. The integrated sensor 12 is equipped with a temperature sensor 13 and a pressure sensor 14. The temperature sensor 13 senses the temperature information inside the storage tank 1, and the pressure sensor 14 senses the air pressure inside the storage tank 1.

[0030] A network module 7 is fixedly connected to the side wall of storage tank 1. The network module 7 supports 4G, 5G, and WiFi. The alarm 6, integrated sensor 12, and electric telescopic rod 15 are all connected to the network through the network module 7. The network module 7 is connected to a smart device 29. The smart device 29 can view the information of the alarm 6 and integrated sensor 12 through the network module 7. The smart device 29 can control the electric telescopic rod 15 through the network module 7. The bottom of storage tank 1 is designed to be arc-shaped to facilitate cleaning of storage tank 1. A valve 30 is provided at the bottom of storage tank 1. Opening the valve 30 allows the wastewater from cleaning to flow away. A second hole 24 is opened in the middle of the connection between the air pressure regulating device 9 and the tank cover 8, connecting the inside of the air pressure regulating device 9 and the inside of storage tank 1. A first hole 21 is opened on the right side wall of the air pressure regulating device 9, which is connected to the second breathing hole 20, allowing air to flow when the second breathing valve 11 is working. The baffle 10 has a hollow cavity inside and is connected to the first breathing hole 17. Block 10 has a hole at the bottom to communicate with the outside air, allowing air to flow when the breathing valve 16 is working. The outer wall of the switch shaft 26 is slidably connected to the middle of the fixed plate 27. A metal spring 31 is fixedly connected to the inner wall of the detection circuit 5. The metal spring 31 controls the operation of the alarm 6. When the metal spring 31 does not contact the disconnect circuit in the detection circuit 5, the alarm 6 does not work. When the metal spring 31 is pushed by the switch shaft 26 to contact the disconnect circuit in the detection circuit 5, the disconnect circuit is connected and the alarm 6 works. The wall thickness of the corrosion simulation tube 2 is the design corrosion allowance of the storage tank 1. In this way, when the corrosion simulation tube 2 is corroded and perforated, the storage tank 1 is still in a safe wall thickness state. The float 25 is made of plastic and has an internal cavity to facilitate buoyancy. The left side wall of the liquid detection device 4 has a hole 3 28. The hole 3 28 is connected to the corrosion simulation tube 2 through the hole in the middle of the flange 3, allowing liquid to enter the liquid detection device 4 from the corrosion simulation tube 2.

[0031] Working principle: When the corrosion simulation tube 2 is perforated by liquid corrosion, liquid from storage tank 1 flows into the corrosion simulation tube 2. The liquid then flows through the hole in the middle of flange 3 into liquid detection device 4. Due to the liquid inflow, float 25 rises, and switch shaft 26 moves upward. Switch shaft 26 then pushes metal spring 31 upward, connecting detection circuit 5. Alarm 6 starts working and sounds an alarm. At the same time, through network module 7, smart device 29 also receives a reminder that the corrosion simulation tube 2 has been perforated by liquid corrosion, indicating that the designed corrosion margin of storage tank 1 has been reached. This allows staff to make immediate plans for maintenance or replacement of storage tank 1, preventing corrosion leaks. Integrated sensor 12 can monitor the temperature and air pressure information inside storage tank 1 in real time. The network module 7 can be used to view the situation on the smart device 29. When the internal air pressure of the storage tank 1 is greater than the external air pressure and exceeds a certain value, the valve disc 18 will be opened by the internal air pressure. Subsequently, the internal air pressure will decrease. After reaching a certain value, the valve disc 18 will close due to the elastic force of the spring 19. When the external air pressure of the storage tank 1 is greater than the internal air pressure and exceeds a certain value, the valve disc 22 will be opened by the external air pressure. Subsequently, the internal air pressure will increase. After reaching a certain value, the valve disc 22 will close due to the elastic force of the spring 23. This can achieve a certain degree of automatic adjustment of the air pressure balance inside and outside the storage tank 1. The electric telescopic rod 15 can also be remotely controlled on the smart device 29 through the network module 7. When the electric telescopic rod 15 is working, it can open the valve disc 18 to achieve the air pressure balance inside and outside the storage tank 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
