Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage tanks, in particular to a chemical storage tank safety detection device. Background Art

[0002] Storage tanks are widely used as a type of equipment for storing media in the petroleum and chemical industries. However, during use, storage tanks are more susceptible to electrochemical corrosion, and the degree of corrosion is more serious than that of the tank wall. Sometimes, corrosion perforation may occur, resulting in oil leakage. The tank bottom is not easy to inspect and repair, and it is also a part that is prone to corrosion. When the bottom plate is welded, the anti-corrosion coating near the weld is often burned, which increases the severity of corrosion. In addition to the parts near the weld that are more susceptible to corrosion, the surrounding parts of the tank body are also susceptible to corrosion. If the surrounding areas of the tank body are not well sealed with asphalt, rainwater or dripping water left along the pipe wall can easily invade the surrounding parts of the tank bottom, forming favorable corrosion conditions. From a practical point of view, the corrosion of the bottom plate of the tank is the most common and the most serious, so a safety monitoring device for chemical storage tanks is needed.

[0003] The prior art has the following shortcomings: Application No. 202010979040.0 in the prior art proposes a chemical storage tank corrosion safety detection device, including a first shell, a second shell, a third shell, a driving device, an acoustic sensor and a controller. The driving device includes a connecting cylinder, a water pump installed in the connecting cylinder, an output pipe connected to the connecting cylinder, and a rotating device for rotating the connecting cylinder. The rotating device includes a first motor, a first gear connected to the output shaft of the first motor, and a second gear connected to the first gear. A first connecting part is connected to the second gear. A support frame is provided on the connecting cylinder, and an adjustment rod is threadedly connected to the support frame. A second connecting part is provided at one end of the adjusting rod, and the first connecting part can be embedded and fixed in the second connecting part. The present invention can analyze, judge and detect the intensity and distribution of corrosion on the bottom and side walls of the storage tank. The detection does not require opening the tank, the downtime is short, and the detection is more convenient and efficient.

[0004] When the above-mentioned device is in use, gas is injected into the first shell to make the detection device float. The water pump sucks the liquid in the storage tank and then sprays it from the output pipe to form a reverse thrust, adjusts the moving direction of the detection device, and receives signals from acoustic sensors in different directions. The detection of the storage tank requires an additional direction adjustment mechanism to perform a comprehensive detection. When it is necessary to detect the positions of storage tanks in different directions and at different heights, multiple adjustments are required, which is time-consuming, labor-intensive, and inconvenient to operate. At the same time, the direction of the detection device is adjusted by sucking the liquid in the storage tank through the water pump and then spraying it from the output pipe to form a reverse thrust. Since the entire device is attached to the tank body, there is inertia during the process of adjusting the direction of the device, and the adjustment accuracy of the device angle is low.
