Description

Technical Field

[0001] The utility model relates to the technical field of oil field on-site control, in particular to an oil pumping well angle tilt automatic stop device. Background Art

[0002] During the production and operation of oil fields, the screws and connecting accessories of the middle shaft, tail shaft, connecting rod and base of the pumping unit may break off due to human factors or the equipment itself during long-term operation, which may lead to the pumping unit flipping over, resulting in a large loss of crude oil production, increasing production costs, and also increasing safety hazards for the staff. In the existing technology, in order to deal with the breakage and flipping accidents of production equipment, the staff only rely on the equipment to check and find the abnormal situation during the inspection work and shut down the production equipment and perform subsequent maintenance work. However, since the manual inspection method cannot be carried out all the time, the efficiency of relying solely on manual inspection of the flipping equipment is low, especially at night or in severe weather such as heavy fog, rain and snow. The inspection work increases further. Moreover, since the inspection work is periodic and the inspection time is fixed, it is impossible to handle and maintain the accident equipment in time in the event of a sudden breakage of production equipment, resulting in the expansion of the accident, and further increase in work costs and production waste. Therefore, in response to the above shortcomings, a pumping unit well angle tilt automatic stop device is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, the present invention provides an automatic stop device for tilting an oil pumping unit, comprising an angle measuring device and a power control device. The angle measuring device is typically mounted on an operating device and monitors the tilt angle of the mounting location in real time during operation. Since the travel and tilt angle range of each moving component of the oil pumping unit are fixed during operation, measuring the tilt angle of the unit itself can be used to determine whether the unit is operating normally. The power control device is used to control the power supply to the operating device. When the operating state of the device is not within the normal range or when the power control device receives remote control, it will cut off the power supply to the operating device, shutting it down.

[0024] The angle measurement device includes a device protection box 4, which is mounted on the surface of the pumping unit's traverse and moves with the operation of the pumping unit. The device protection box 4, as the main body of the angle measurement device, primarily serves to install, manufacture, and protect the device. After the other components of the angle measurement device are installed in the device protection box 4, the installation location of the device protection box 4 becomes the installation and operating location of the angle measurement device. During the operation of the pumping unit, the top of the pumping unit's traverse is connected to the pumping unit's walking beam and periodically swings left and right with the movement of the walking beam. During this swinging process, since the pumping unit's operating state generally does not change, the swing amplitude of the pumping unit's traverse is fixed during normal operation. Mounting the device protection box 4 on the pumping unit's traverse reduces measurement difficulty. If the pumping unit flips due to factors such as bolt or accessory breakage or damage, the walking beam, under the influence of its own inertia and gravity, will flip beyond the normal operating angle, causing the pumping unit's traverse to move beyond its normal operating angle range. At this time, the angle measurement device will record the data collected that exceeds the operating range.

[0025] The device protection box 4 houses an angle sensor 2 and a signal transmitter 5. The output of the angle sensor 2 is connected to the output of the signal transmitter 5. Once the angle sensor 2 is installed in its working position with the device protection box 4, it can measure the tilt angle of the pumping well transom in real time and transmit the measurement results to the signal transmitter 5, which then transmits them to the power control device and the main control system.

[0026] It should be noted that the angle sensor 2 is equipped with a data processing module. This module processes the angle information measured by the angle sensor 2 and transmits the processed signal to the signal transmitter 5. The data processing system processes the angle information measured by the angle sensor 2. Typically, the normal operating angle of the pumping unit's lateral barge is input into the data processing module before installation. After the angle sensor 2 measures the data, the data processing module compares the measured data with the pre-input angle range. If the measured angle is within the normal operating angle range, the device is operating normally. In this case, the data processing module controls the angle sensor 2 to not transmit a signal to the signal transmitter 5. If the data processing module compares the angle sensor 2's measurement result with the normal operating angle range and the measurement result is not within the normal operating angle range, it indicates that the pumping unit's lateral barge and the pumping unit are operating in a fault state. The data processing module transmits the angle sensor 2's measurement result to the signal transmitter 5, which then transmits the fault information to the power supply control device. The data processing module analyzes and filters the angle sensor 2's measurement results and only transmits a signal when the device fails, reducing the workload of the signal transmitter 5 and extending the device's service life.

[0027] In the present invention, the power control device includes a switch control module 1, which is installed in a ground distribution box. The output end of the switch control module 1 is connected to the power switch in the ground distribution box. Upon receiving a control signal, the switch control module 1 can immediately cut off the power switch in the ground distribution box to power off the running equipment. In order to achieve signal transmission between the switch control module 1 and the angle sensor 2, a signal receiver is provided in the switch control module 1. The signal receiver cooperates with the signal transmitter 5 to transmit data. The switch control module 1 shuts down the power in the ground distribution box according to the received signal. The switch control module 1 cooperates with the angle measuring device to measure the operating angle of the device through the angle sensor 2 as soon as a device fault occurs and transmit the fault data to the switch control module 1 via the signal transmitter 5. The switch control module 1 then shuts down the faulty equipment. The fast response speed allows for timely shutdown of equipment with operating faults, preventing equipment accidents from escalating while reducing production losses and improving the safety of the device.

[0028] Among them, the power control device is provided with an alarm device, and the alarm device is connected to the switch control module 1, and sends an alarm signal after the switch control module 1 is actuated. The alarm device sends an alarm signal to the staff at the same time as the switch control module 1 cuts off the power to the faulty equipment, reminding the staff to handle and repair the faulty equipment in time. Normally, the alarm signal includes sound signal, light signal and electronic signal. The alarm device is provided with a speaker and a warning light, which are used to send light signal and sound signal respectively for warning. When there are staff patrolling around, the staff patrolling around can be notified in the first time to handle the accident. In addition, the alarm device is also provided with a wireless signal transmission device connected to the on-site Internet of Things, which sends the alarm electronic signal to the main control terminal in the control room to remind the staff in the main control terminal to respond in time. In order to ensure the normal operation of the alarm device, a separate DC power supply is usually provided in the on-site power distribution cabinet to power the alarm device.

[0029] It should be noted that a reset switch 3 is provided between the switch control module 1 and the power supply in the distribution box. The reset switch 3 plays a protective role between the switch control module 1 and the power supply of the distribution box. After the switch control module 1 cuts off the power supply of the distribution box, the reset switch 3 acts synchronously to keep the power supply of the distribution box in the disconnected state. At this time, even if the power supply of the distribution box is closed, the power supply cannot be restored. Only after resetting the reset switch 3 can the power supply be restored to prevent the occurrence of accidental touch. Normally, the reset switch 3 is a relay, and the switch control module 1 and the power supply of the distribution box are connected to the two ends of a group of normally open contacts of the reset switch 3 of the relay. When the distribution box stops supplying power, the relay loses power and the normally open contacts are separated. At this time, if you want to restore the power supply, you need to close the reset switch first, otherwise the normally open contacts are always in the disconnected state and the power supply cannot be restored, thereby playing a role in preventing accidental touches, and avoiding further expansion of the accident caused by accidentally restoring the power supply during work.

[0030] like Figure 1 As shown, the device protection box 4 is equipped with a power supply module 7, which is connected to the angle sensor 2 and the signal transmitter 5. This power supply module 7 provides power to the angle sensor 2 and the signal transmitter 5 within the device protection box. Typically, a separate DC power supply is required within the on-site power distribution cabinet to ensure that the power supply module 7 can continue to function even after the switch control module 1 shuts off the power within the distribution cabinet. The power supply for the power supply module 7 can share the same DC power supply as the alarm device within the distribution cabinet.

[0031] The outer surface of the device protection box 4 is provided with a solar panel, which is connected to the power supply module 7. The solar panel can convert solar energy into electrical energy during operation. The solar panel inputs the converted electrical energy into the power supply module 7 to provide a power source for the power supply module 7. In this case, the power supply module 7 does not need to be connected to the power supply in the distribution box to provide power for components such as the angle sensor 2 and signal transmitter 5 in the angle measuring device, thereby reducing the wiring work and workload during the device installation process.

[0032] It should be noted that the device protection box 4 is of magnetic type, including a main body and an opening and closing cover, and a magnet 6 is provided on the inner surface edge of the cover. The device protection box 4 is mainly used to protect the angle sensor 2 and the signal transmitter 5 installed therein, and prevent the external dust, rainwater and other debris from contacting the angle sensor 2 and the signal transmitter 5 during operation, causing the device to malfunction. Normally, the main body and the cover are connected by two hinges to achieve an opening and closing connection between the cover and the main body. The main body is generally made of metal material. When the cover is buckled with the main body, the magnet on the inside of the cover absorbs the main body under the action of its own magnetism, thereby fixing the cover on the main body to improve the airtightness of the device protection box 4.

[0033] During actual operation, the normal operating angle range of the pumping unit varies depending on the operating conditions of the unit. When the operating conditions of the unit change, the normal operating angle range stored in the data processing module needs to be modified. Generally, the data processing module can be connected to a field control terminal, and the normal operating angle in the data processing module can be modified through the field control terminal after the operating conditions are modified.

[0034] Combine Figures 1 to 3 The following is a detailed description of the steps when this pumping well angle tilt automatic stop device works:

[0035] Step 1: Input the normal operating angle range into the data processing module according to the actual working status, and install the angle measuring device on the surface of the pumping well transom after assembling it according to the device structure.

[0036] Step 2: Start the pumping unit and monitor its operating angle in real time using the angle measurement device. As the pumping unit's horizontal barge periodically swings left and right as the unit operates, the angle measurement device synchronizes with the horizontal barge. The internal angle sensor measures its own angle in real time and sends the results to the data processing module.

[0037] Step 3: The data processing module processes the received data and sends a fault signal to the signal transmitter when the pumping unit fails. During this process, the data processing module continuously compares the received data with the pre-entered angle range. When the measured angle is within the pre-entered range, it indicates that the pumping unit is operating normally. When the pumping unit fails, it will cause a rollover accident. At this time, the pumping unit's walking beam drives the pumping unit well cross-ship out of the normal working position, causing the pumping unit well cross-ship's working angle to exceed the normal working range. At this time, the data processing module compares the data outside the working range and sends it to the signal transmitter, which then sends it to the power control device.

[0038] Step 4: After receiving the control signal from the signal transmitter, the power control device turns off the power switch in the ground distribution cabinet to cut off the power supply to the oil pump. At the same time, the alarm device sends an alarm signal to the surrounding area and the control room for warning.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
