The digital oil field construction concept is proposed since 1999, a plurality of oil fields are formed in a certain scale, but some remote oil wells are not covered by 4G and 3G signals, but the short message and telephone communication functions of the area where the oil well is located can be normally used. In addition, crude oil in a remote oil well does not directly enter an oil pipeline, but is directly stored in an oil storage tank beside the oil well, so that the crude oil level needs to be detected in advance in an artificial oil measuring mode when oil is needed to be transported, the process is complex, and potential safety hazards are large. Therefore, it is necessary to reasonably utilize the short message and telephone communication functions of the region where the oil well is located to carry out intelligent digital management on the oil well.
Fig. 1 is a schematic structural diagram of a liquid level monitoring device for an oil storage tank provided by an embodiment of the present invention. As shown in fig. 1, the oil storage tank liquid level monitoring apparatus includes: the liquid level transmitter 1, the short message alarm 2 and the contactor 3. The liquid level transmitter 1 is located on a pipeline communicated with the oil storage tank 5, the short message alarm 2 is provided with an analog input port and a switching value output port, the analog input port is electrically connected with the liquid level transmitter 1, the input port of the contactor 3 is electrically connected with the switching value output port, and the output port of the contactor 3 is electrically connected with a control circuit of the oil pumping unit of the oil storage tank 5.

In the embodiment, the short message alarm is a remote data acquisition and control terminal device based on a single chip microcomputer and a GSM wireless communication technology, comprises a multi-way switching value, an analog input function and a switching value output function, and can drive the contactor 3; the built-in GSM module can communicate with the GSM terminal.
In the embodiment of the utility model, the oil storage tank liquid level monitoring device detects the crude oil liquid level height in the oil storage tank through the liquid level transmitter, and inputs the detected result into the short message alarm through the analog input port, and the short message alarm is internally provided with the communication module, and the detected result of the liquid level transmitter can be sent to technical personnel in the form of short messages through the communication module, thereby needing no manual oil measurement, avoiding the potential safety hazard, reducing the frequency of manual well patrol and reducing the well patrol cost; meanwhile, the liquid level monitoring device of the oil storage tank is also electrically connected with the input port of the contactor and the switching value output port of the short message alarm, and the output port of the contactor is electrically connected with the control circuit of the pumping unit of the oil storage tank, so that when crude oil in the oil storage tank overflows, the control circuit of the pumping unit of the oil storage tank can be disconnected through the contactor, the pumping unit stops pumping oil to avoid the fact that the crude oil is full, and safety is improved.
In this embodiment, the level transmitter is a transmitter that is mounted directly on a pipe or vessel, for example, the level transmitter may be mounted on a pipe 500mm from the bottom of the storage tank. Because the isolation diaphragm is directly contacted with the liquid medium, the positive pressure side is not required to be led out by a pressure guide pipe, the height of the current liquid is calculated by the pressure change of a densimeter of the liquid according to the pressure sensing principle, and the liquid level of the medium with high temperature, high viscosity, easy crystallization, easy precipitation, strong corrosion and the like can be measured. In this embodiment, the liquid level transmitter may convert the calculated current liquid height into a 4 to 20mA direct current signal and output the signal to the analog input port, and the short message alarm 2 may convert the direct current signal into a liquid level height after acquiring the signal, and send the height to a technician through a GSM module by a short message.
Optionally, the liquid level transmitter 1 and the contactor 3 are both electrically connected with the short message alarm 2 by a shielding signal wire 4. As shown in fig. 2, the shielding signal line 4 includes a signal conductor 41 and a shielding layer 42 covering the signal conductor 41, the shielding signal line 4 is formed by covering a shielding layer 41 outside the signal conductor 41 to achieve an anti-interference effect, the shielding layer 41 is a braided copper mesh or copper foil (aluminum), and the shielding layer 41 needs to be grounded when in use, so that an external interference signal is guided into the ground by the shielding layer, thereby preventing the interference signal from entering an inner conductor to be dried and simultaneously reducing the loss of a transmission signal.

The proximity switch 6 is used as a sensor, has the characteristics of reliable action, stable performance, long service life, strong anti-interference capability and the like, can be in a hot standby relation with the contactor 3, and improves the reliability of the oil storage tank liquid level monitoring device.

Optionally, the outer surface of the hollow block 7 has a corrosion resistant coating. Illustratively, the anti-corrosive coating may be an electrostatic conductive coating layer, such as conductive carbon black and toner, conductive mica compound powder. The hollow block 7 is coated with the anticorrosive coating, so that the requirements of oil resistance, chemical medium resistance, corrosion resistance and static conduction of the hollow block can be met, and the safe use of the hollow block is ensured.
In some possible implementations, the contactor 3 and the proximity switch 6 are connected in series on the control circuit of the pumping unit of the storage tank 5. When the contactor 3 is connected with the proximity switch 6 in series, the oil pumping unit can stop working as long as any one of the contactor 3 and the proximity switch 6 is operated to disconnect the control circuit, namely, the proximity switch 6 and the contactor 3 are in a hot standby relation with each other, and the reliability of the oil storage tank liquid level monitoring device is improved.
