Description

Technical Field

[0001] The utility model belongs to the technical field of tank area leakage regulation, in particular to an automatic interlocking device for irrigation area leakage. Background Art

[0002] Safety and environmental protection are extremely important in the daily operation and management of oil tank farms. In the traditional sewage system of oil tank farms, there are usually two systems: one is used to discharge rainwater, and the rainwater generated by rain is directly discharged into the rainwater system through the rainwater pipes on the ground; the other is used to discharge sewage containing oil pollution, and the oily sewage generated after cleaning the inside of the oil tank is discharged into the sewage system through the sewage pipes;

[0003] However, these two systems often operate independently. When an oil tank leaks, the leaked medium will flow to the ground and be directly discharged into the rainwater system through the rainwater pipe on the ground, causing environmental pollution and increased subsequent treatment costs. Therefore, there is an urgent need for a device that can automatically switch the rainwater drainage system to the sewage oil and water drainage system when a leak occurs in the tank area to prevent pollutants from flowing into the rainwater system, thereby protecting the environment and ensuring safety. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic interlocking device for irrigation area leakage comprises a protection frame, a first pipe is connected through the left side surface of the protection frame, a liquid level sensor is connected through the upper surface of the first pipe, a diversion mechanism is arranged at the left end of the first pipe, a fixed plate is installed at the left end of the upper surface of the protection frame, a fixing bolt is movably connected through the left end of the upper surface of the fixing plate, and an online viscosity sensor is installed at the right end of the upper surface of the fixing plate; cleaning mechanisms are arranged on the upper and lower side surfaces of the fixing plate between the fixing bolt and the online viscosity sensor.

[0007] Furthermore, the diversion mechanism includes a second pipeline, a first valve is installed at the rear end of the second pipeline, a second valve is installed at the front end of the second pipeline, and a third pipeline is installed at the left ends of the first valve and the second valve.

[0008] Furthermore, the cleaning mechanism includes a driving mechanism, a threaded rod is installed at the output end of the driving mechanism, the lower end of the threaded rod is rotatably connected to a stopper, and the external thread of the threaded rod is connected to a lifting block, the interior of the lifting block is located on the right side of the threaded rod and is movably connected to a sliding rod, and a connecting rod is installed at the right end of the lifting block, a connecting ring is installed at the right end of the connecting rod, and a cleaning ring is installed inside the connecting ring.

[0009] Furthermore, the lower end of the fixing bolt is threadedly connected to the inside of the protection frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a liquid level sensor and an online viscosity sensor. When the liquid level sensor detects that the fluid is almost full and the online viscosity sensor detects that the fluid viscosity is less than the target value, it is judged as rainwater, and the rainwater in the protection frame is discharged into the rainwater system. When the online viscosity sensor detects that the fluid viscosity is greater than the target value, it is judged as a medium leaking from the tank body, and the leaked medium in the protection frame is discharged into the sewage system, which effectively avoids the leakage of the medium in the tank area from flowing into the rainwater system to cause pollution.

[0024] The protection frame 1 is constructed outside the oil tank 21 in the tank area, and is preferably cast with cement;

[0025] The first valve 6 and the second valve 7 are preferably electric valves;

[0026] The liquid level sensor 3 is used to detect the liquid level height inside the first pipe 2; the online viscosity sensor 11 is used to detect the fluid viscosity, which is set with a target value; when the liquid level sensor 3 detects that the fluid inside the first pipe 2 is almost full, and the detection value of the online viscosity sensor 11 is less than the target value, it is rainwater, the first valve 6 is opened, the second valve 7 is closed, and the rainwater accumulated in the protection frame 1 is discharged to the rainwater system; when the detection value is greater than the target value, it is the medium leaking from the oil tank 21, the first valve 6 is closed, the second valve 7 is opened, and the leaked medium accumulated in the protection frame 1 is discharged to the sewage system;

[0027] The liquid level sensor, the first valve 6, the second valve 7, and the online viscosity sensor 11 are all electrically connected to the external control system for automatic operation.

[0028] exist Figure 3 and Figure 4 Middle: A cleaning mechanism 12 is arranged between the fixing bolt 10 and the online viscosity sensor 11 on the upper and lower surfaces of the fixing plate 9. The cleaning mechanism 12 includes a driving mechanism 13. The driving mechanism 13 is installed on the upper surface of the fixing plate 9. A threaded rod 14 is installed on the output end of the driving mechanism 13. A stopper 15 is rotatably connected to the lower end of the threaded rod 14. A lifting block 16 is threadedly connected to the outer surface of the threaded rod 14. The interior of the lifting block 16 is located on the right side of the threaded rod 14 and is movably connected with a sliding rod 17.

At this time, the liquid level sensor 3 detects that the fluid in the first pipe 2 is almost full, and the online viscosity sensor 11 detects that the viscosity of the fluid is greater than the target value, the system determines that it is the medium leaking from the oil tank 21, the first valve 6 is closed, and the second valve 7 is opened, and the leaked medium accumulated in the protection frame 1 is discharged into the sewage system, thereby avoiding the leakage of the medium discharged into the rainwater system to cause pollution; the driving mechanism 13 is started once at a certain interval, driving the threaded rod 14 to rotate, so that the lifting block 16 threadedly connected to the threaded rod 14 is lifted and lowered, thereby driving the cleaning ring 20 to clean the detection end of the online viscosity sensor 11.
