Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

Since field equipment such as an oil well is low in safety because it is located remotely and unattended, it is necessary to provide field equipment with an antitheft device to prevent a thief from wantonly stealing it.

Taking an oil well as an example, a remote pumping unit oil well of the oil field is far away from a crude oil gathering and transporting pipe network, crude oil produced in the oil well is generally temporarily stored in an oil storage tank, and when the crude oil stored in the oil storage tank reaches a certain amount (which can be measured by the unit of height), the oil pipe can be pulled to a united station by an oil storage tank truck for crude oil treatment. In addition, an oil outlet oil filling riser (hereinafter, referred to as oil filling riser) and an oil filling riser gate are generally connected outside the oil storage tank, and the oil stored in the oil storage tank can flow out through the oil filling riser by controlling the oil filling riser gate, so that the oil extraction is completed.

Based on above structure, refer to fig. 1, can set up the chain at present and twine on oil filling riser and oil filling riser gate to lock the chain through the tapered end, thereby reach protection oil filling riser gate, avoid stealing the oil molecule and steal oil from the oil storage tank through the oil filling riser gate, tapered end and chain constitute prior art's anti-theft device. However, with the structure shown in fig. 1, the oil stealing molecules can still destroy the lock head by some bad means and open the crane pipe gate to steal oil. The phenomenon of oil theft not only causes serious loss to national property, but also pollutes the environment.

The embodiment of the utility model provides the anti-theft alarm device which is simple in structure, convenient to install and capable of effectively and reliably realizing anti-theft. When the oil-stealing prevention device is applied to an oil well, the phenomenon that oil-stealing molecules illegally steal oil can be effectively avoided, and certain guarantee is brought to national economic and social benefits. The following embodiments of the present invention will be described with reference to the case where the anti-theft alarm device is applied to an oil well.

Fig. 2 is a schematic structural diagram of an anti-theft alarm device according to an embodiment of the present invention. If the anti-theft alarm device is applied to an oil well for anti-theft, the distance between the anti-theft alarm device and the oil well can be smaller than the distance threshold value, namely the anti-theft alarm device is arranged close to the oil well. If the anti-theft alarm device is applied to other field equipment, the anti-theft alarm device is arranged close to the field equipment in the same way. As shown in fig. 2, the burglar alarm arrangement may comprise: power supply 10, monitoring circuit 20, control circuit 30, and remote alarm circuit 40.

Wherein, the power source 10 can be connected with the monitoring circuit 20, the control circuit 30 and the remote alarm circuit 40 respectively. The power supply 10 may be used to power the monitoring circuitry 20, the control circuitry 30 and the remote alarm circuitry 40.

For example, power supply 10 may be connected to a utility power source and provide power to the connected structure (including monitoring circuitry 20, control circuitry 30, and remote alarm circuitry 40) under the control of electrical signals provided by the utility power source.

The monitoring circuit 20 may also be connected to a control circuit 30. The monitoring circuit 20 may be adapted to send a drive signal to the control circuit 30 when an obstacle is detected.

Optionally, the monitoring circuit 20 may have an obstacle monitoring function, such as infrared monitoring, photoelectric monitoring, and the like. In this way, the monitoring circuit 20 can reliably monitor the obstacle through the obstacle monitoring function provided therein, and send a driving signal to the control circuit 30 in time when the obstacle is monitored. Alternatively, the monitoring circuit 20 may determine that an obstacle is present when its circuit structure is damaged, and send a driving signal to the control circuit 30 in time. Furthermore, when applied to an oil well, the barrier may be referred to as oil-stealing molecules.

The control circuit 30 may also be connected to a remote alarm circuit 40. The remote alarm circuit 40 may also be used to establish a communication connection with a terminal. The control circuit 30 may be configured to control the remote alarm circuit 40 to send alarm information to the terminal based on the driving signal.

Optionally, a software program for controlling the remote alarm circuit 40 to send alarm information to the terminal may be pre-embedded in the control circuit 30. The remote alarm circuit 40 may be embedded with a global system for mobile communications (GSM) card, and the remote alarm circuit 40 may establish a remote communication connection with a terminal to which a user (e.g., a person on duty managing an oil well, or a police officer) belongs through the GSM card.

When the control circuit 30 receives the driving signal sent by the monitoring circuit 20, it can control the remote alarm circuit 40 to send alarm information to the terminal by scanning the internal software program. When the alarm information is used for oil well theft prevention, the alarm information can be used for indicating that a user to which the terminal belongs has oil stealing molecules and taking measures to capture in time.

In summary, the embodiment of the present invention provides an anti-theft alarm device, which includes a monitoring circuit, a control circuit and a remote alarm circuit. Because the monitoring circuit can drive the control circuit to control the remote alarm circuit to send alarm information to the terminal when monitoring the obstacle, the remote monitoring of the oil well located at a remote place can be realized, so that a user (such as an operator on duty) to which the terminal belongs can timely catch a thief in the oil well based on the received alarm information, and the anti-theft reliability is improved.

Optionally, in the embodiment of the present invention, the remote alarm circuit 40 may be a global positioning system GPS alarm. For example, the remote alarm circuit 40 may be of the type: TR 130.

Optionally, fig. 3 is a schematic structural diagram of another burglar alarm provided in the embodiment of the present invention. As shown in fig. 3, the burglar alarm arrangement may further comprise: a field alarm circuit 50.

Wherein the power supply 10 may also be connected to the field alarm circuit 50. The power supply 10 may also be used to power the field alarm circuit 50.

The control circuit 30 may also be connected to a field alarm circuit 50. The control circuit 30 may also be configured to control the on-site alarm circuit 50 to send out an alarm message after controlling the remote alarm circuit 40 to send an alarm message target duration to the terminal based on the driving signal.

Optionally, a software program for controlling the field alarm circuit 50 to send out a warning message may be pre-embedded in the control circuit 30, and the software program may include information of the target duration. For example, the target time period may be half an hour, i.e., 30 minutes. Thus, in the embodiment of the present invention, when receiving the driving signal, the control circuit 30 may control the remote alarm circuit 40 to send alarm information to the terminal by scanning the internal software program, and then control the on-site alarm circuit 50 to send out an alarm message at the interval target duration.

Optionally, the on-site alarm circuit 50 may be a voice alarm, such as a set of dc 24 volt (V) voice alarms, model 125 db. Accordingly, the warning message may be a voice warning message. For example, the content of the voice warning message may be: "you have been surrounded by police officers". By further providing the on-site alarm circuit 50, the antitheft reliability can be further ensured.

Of course, the on-site alarm circuit 50 may also be a circuit device capable of sending out warning information, such as a light alarm, an audible and visual alarm, and the like, which is not limited in the embodiment of the present invention.

Optionally, in the embodiment of the present invention, the control circuit 30 may be a programmable logic module. Such as programmable logic modules, model FX1N-10 MR. Thus, as can be seen in connection with the still another burglar alarm arrangement shown in fig. 4, the control circuit 30 may comprise at least: an input terminal X0, a ground terminal 0V, a first output terminal Y0, a second output terminal Y1, and a common terminal COM 0.

Optionally, with continued reference to fig. 4, the monitoring circuit 20 may include: at least one opposed photoelectric switch 201, each opposed photoelectric switch 201 may include an optical transmitter and an optical receiver.

For example, referring to fig. 4 and 5, still another burglar alarm is shown, each of which shows two opposed photoelectric switches 201. And as can be seen with reference to fig. 5, a correlation-type photoelectric switch 201 may include: an optical transmitter 2011_1 and an optical receiver 2012_ 1; another opposed-type photoelectric switch 201 may include: an optical transmitter 2011_2 and an optical receiver 2012_ 2.

Referring to fig. 4 again, the first output terminal ON1 of each correlation photoelectric switch 201 may be connected to the input terminal X0 of the control circuit 30, and the second output terminal COM1 of each correlation photoelectric switch 201 may be connected to the ground terminal 0V of the control circuit 30. Each of the opposed-type photoelectric switches 201 may be configured to determine that an obstacle is present when the light emitted from the light emitter 2011 to the light receiver 2012 is blocked, and to send a driving signal to the control circuit 30 through the first output terminal ON1 and the second output terminal COM 1. That is, the correlation photoelectric switch 201 may have an obstacle monitoring function. Of course, the correlation photoelectric switch 201 may determine that an obstacle is present when it is damaged.

Alternatively, for each correlation photoelectric switch 201, the first output terminal ON1 and the second output terminal COM1 thereof may be referred to as a normally-ON point, and a relay switch may be connected between the two terminals. When the bijective photoelectric switch 201 is operating normally, the relay switch between the first output terminal ON1 and the second output terminal COM1 may be in a closed state, that is, the normally open points ON1 and COM1 of the bijective photoelectric switch 201 may be closed. When the bijective photoelectric switch 201 detects an obstacle, the relay switch between the first output terminal ON1 and the second output terminal COM1 thereof may be in an open state, that is, the normally open points ON1 and COM1 of the bijective photoelectric switch 201 may be open. In this way, the driving signal received by the control circuit 30 may be the connection state of the normally open point ON1 and COM1 of the correlation photoelectric switch 201.

Alternatively, with reference to fig. 1 and 5, an anti-theft lock 00 may be provided on a crane pipe gate of a storage tank connected outside an oil well, and the anti-theft lock 00 may refer to the structure shown in fig. 1. In the embodiment of the present invention, in each correlation photoelectric switch 201, the optical transmitter and the optical receiver may be oppositely disposed on two sides of the anti-theft lock 00.

Since the oil thief generally needs to steal oil by destroying the anti-theft lock 00, it can be known from the principle of monitoring an obstacle by the correlation photoelectric switch 201 described in the above embodiment that the light emitter and the light receiver are oppositely disposed on both sides of the anti-theft lock 00, and when the oil thief destroys the anti-theft lock 00, the light emitted by the light emitter is naturally shielded. Further, the opposite-emitting photoelectric switch 201 can reliably detect the obstacle.

For example, referring to fig. 5, two opposed photoelectric switches 201 are shown, in which the optical transmitters 2011_1 and 2011_2 are located on the same side and are disposed opposite to each other, and the optical receivers 2012_1 and 2012_2 are located on the same side and are disposed opposite to each other. Thus, the light rays emitted by the light emitters 2011_1 and 2011_2 of the two correlation photoelectric switches 201 can intersect at the same target point P1, and the target point P1 can also be referred to as a correlation beam focus.

Alternatively, the target point P1 may be spaced less than a spacing threshold from the riser gate of the well. In this way, the reliability of monitoring the obstacle by the correlation photoelectric switch 201 can be further ensured. For example, the spacing may refer to a vertical spacing, and the spacing threshold may be about 10 centimeters or so. If the distance threshold is 10 cm, the vertical distance between the target point P1 and the crane pipe gate is 10 cm.

Optionally, the type of the correlation photoelectric switch 201 may be GDK-50. Wherein, GDK refers to model identification, and 50 refers to the straight-line distance between the optical transmitter and the optical receiver being 50 meters.

In addition, the two opposite-emitting photoelectric switches 201 can be diagonally installed on a well site fence with the height of 3 meters, so that the obstacle can be reliably monitored while the obstacle is prevented from being found by an oil thief.

With continued reference to fig. 4, the ground terminal 0V of the control circuit 30 may also be connected to the negative output terminal (-) of the power supply 10, and the common terminal of the control circuit 30 may be connected to the positive output terminal (+) of the power supply 10. Further, referring to fig. 4, the input side of the control circuit 30 also has a positive electrode power supply terminal 24V, and the positive electrode power supply terminal 24V is also connected to the positive electrode output terminal (+) of the power supply 10.

The first output terminal Y0 of the control circuit 30 may be connected to the positive power supply terminal (+) of the remote alarm circuit 40, and the second output terminal Y1 of the control circuit 30 may be connected to the positive power supply terminal (+) of the field alarm circuit 50. The negative power terminal (-) of the remote alarm circuit 40 and the negative power terminal (-) of the on-site alarm circuit 50 may both be connected to the negative output terminal (-) of the power supply 10.

In combination with the above connection manner, in the embodiment of the present invention, the control circuit 30 may be configured to control the positive power source terminal (+) and the negative power source terminal (-) of the remote alarm circuit 40 to be disconnected based on the received driving signal. Accordingly, the remote alarm circuit 40 is disconnected from the power supply 10, that is, the power supply 10 stops supplying power to the remote alarm circuit 40, and thus, the alarm information may include power-off information. In addition, the control circuit 30 may be configured to control the positive power terminal (+) and the negative power terminal (-) of the field alarm circuit 50 to establish a connection after a target time period based on the received driving signal. Accordingly, the on-site alarm circuit 50 can establish a reliable connection with the power supply 10 and issue an alarm message upon activation of the power supply 10.

It can also be determined based on the above description that when no obstacle is detected, the remote alarm circuit 40 establishes a normal connection with the power supply 10, and the power supply 10 supplies power to the remote alarm circuit 40. And the site alarm circuit 50 is not connected to the power supply 10, the power supply 10 does not supply power to the site alarm circuit 50.

With reference to the structures shown in fig. 4 and 5, taking the target time duration as 30 minutes, the remote alarm circuit 40 as the GPS alarm shown in fig. 4, and the on-site alarm circuit 50 as the voice alarm shown in fig. 4 as an example, the operation principle of the burglar alarm device according to the embodiment of the present invention is described as follows:

in the absence of oil theft, for each correlation photoelectric switch 201, the first output terminal ON1 and the second output terminal COM1, i.e., the normally open points ON1 and COM1, may be in a closed state. When oil stealing molecules destroy the anti-theft lock 00 installed at the loading arm gate, the opposite light column of the opposite photoelectric switch 201 is shielded, and the normally open point ON1 and COM1 of the opposite photoelectric switch 201 are disconnected. Alternatively, when the oil-stealing molecule destroys the correlation photoelectric switch 201, the normally open point ON1 and COM1 of the correlation photoelectric switch 201 will be opened. Further, the input terminal X0 and the ground terminal 0V of the control circuit 10 lose the closed signal input, that is, the input terminal X0 and the ground terminal 0V of the control circuit 10 are disconnected, it can be understood that the digital signal 0 is input to both the input terminal X0 and the ground terminal 0V, and the driving signal sent to the radial photoelectric switch 201 is 0. Accordingly, the control circuit 10 may start to cyclically scan the built-in software program to disconnect the first output terminal Y0 from the common terminal COM0 and then connect the second output terminal Y1 to the common terminal COM0 after the target duration. As is clear from the description of the above embodiment, the positive power supply terminal (+) and the negative power supply terminal (-) of the remote alarm circuit 40 are disconnected, and the power supply 10 stops supplying power to the remote alarm circuit 40. And then half an hour later, the positive power supply terminal (+) and the negative power supply terminal (-) of the on-site alarm circuit 50 are connected, and the power supply 10 starts to supply power to the on-site alarm circuit 50. This can be such that: firstly, the remote alarm circuit 40 remotely sends power-off alarm information to the connected terminal, and the user of the terminal can gather the police power gripping time to capture oil stealing molecules based on the received power-off alarm information. Second, half an hour after the alarm is sent, the on-site alarm circuit 50 starts to send a voice alarm. Therefore, the oil stealing molecules can be reliably caught, and the anti-theft reliability is ensured.

Optionally, in the embodiment of the present invention, the power supply 10 may be a dc switching power supply. For example, the model number of the power supply 10 may be: s-25-24. That is, the power supply 10 can provide a direct current 24V electrical signal to the connected circuitry.

Optionally, referring to fig. 4, the power supply 10 may be connected to the commercial power through the live line L and the neutral line N. The positive power supply terminal (+) of each of the corresponding pair of the photoelectric switches 201 is connected to the positive output terminal (+) of the power supply 10, and the negative power supply terminal (-) of each of the corresponding pair of the photoelectric switches 201 is connected to the negative output terminal (-) of the power supply 10.

Based on the records of the embodiments, the anti-theft alarm device provided by the embodiment of the utility model has the advantages of simple structure and convenience in installation, and is suitable for drawing oil storage tanks and crane pipe gates of outdoor unattended remote oil pumping units and oil wells of various oil systems. And the purpose of guarding against self-stealing can be achieved, so that users (such as public security guard personnel) can capture oil stealing molecules in time, national property is effectively protected, and certain economic benefit and social benefit are achieved.

In embodiments of the present invention, the terms "first", "second", third "and" fourth "are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "at least one" may mean one or more than one.

The utility model is not to be considered as limited to the particular embodiments shown and described, but is to be understood that various modifications, equivalents, improvements and the like can be made without departing from the spirit and scope of the utility model.
