High-frequency oscillating wave capacitance method oil leakage detection and alarm device

Abstract

The invention discloses a high-frequency oscillating wave capacitance method oil leakage detection and alarm device comprising a water tank, a detector and a converter. The water tank is arranged at the low position of the tank field of an oil storage tank. The detector is arranged on the water surface. The signal output end of the detector is connected with the signal input end of the converter through a cable. The power supply end of the detector is connected with a power supply through the converter. The detector comprises a shell and a detection circuit arranged in the shell. An electrode is arranged on the detection circuit. The upper end of the electrode is connected in series with the detection circuit, and the lower end is arranged under the water surface. The converter comprises a shell and a conversion circuit arranged in the shell. The input end of the conversion circuit is connected with the output end of the detection circuit. The output end of the conversion circuit is connected with an alerter. The phenomenon of oil leakage can be accurately detected in real time and alarming can be performed so as to be safe and reliable.

Description

technical field [0001] The invention relates to the technical field of oil leakage alarms, in particular to a high-frequency oscillatory wave capacitance method oil leakage detection and alarm device. Background technique [0002] During the use of the oil storage tank, if the welding process of the oil storage tank is not up to standard, there is a risk of oil leakage in the oil storage tank. The leaked oil not only pollutes the environment, but also easily causes fire accidents, which is harmful to personal and property safety. cause huge losses. [0003] Existing oil sealing devices are generally inspected by personnel on a regular basis, but manual inspection will inevitably have loopholes, which not only increases the workload of the staff, but also has poor inspection results, especially the traces of oil storage tanks cannot be found in time Leakage phenomenon. At the same time, regular inspections also have time loopholes, and leakage accidents that occur during th...

[0002] During the use of the oil storage tank, if the welding process of the oil storage tank is not up to standard, there is a risk of oil leakage in the oil storage tank. The leaked oil not only pollutes the environment, but also easily causes fire accidents, which is harmful to personal and property safety. cause huge losses

[0003] Existing oil sealing devices are generally inspected by personnel on a regular basis, but manual inspection will inevitably have loopholes, which not only increases the workload of the staff, but also has poor inspection results, especially the traces of oil storage tanks cannot be found in time Leakage phenomenon

At the same time, regular inspections also have time loopholes, and leakage accidents that occur during the inspection cycle cannot be discovered in time

[0004] At present, the detection of oil storage tanks generally adopts ultrasonic detection technology. This detection method has high detection accuracy, but the price is also surprisingly high, which is completely unsuitable for the current application requirements of our country.
