Description

Technical Field

[0001] This invention relates to the field of oil well system technology, and in particular to an oil well system with a remote-controlled anti-theft valve for uncontrolled blocks in overseas oil fields. Background Technology

[0002] In existing technologies, oil wells are susceptible to loss of control over production areas, making it impossible to guarantee the normal operation and maintenance of oil well equipment. This could lead to a series of safety hazards, such as crude oil leaks causing pollution to the local environment. Furthermore, companies struggle to rationally plan the extraction and utilization of resources, resulting in resource waste.

[0003] Therefore, it is urgent to develop an oil well system with remote-controlled anti-theft valves for out-of-control blocks in overseas oil fields. This system would allow for remote control of critical oil well equipment even in the event of a well malfunction, reducing resource waste, ensuring equipment safety, and mitigating potential environmental hazards. Summary of the Invention

[0004] To address the aforementioned technical problems, embodiments of the present invention provide an oil well system with a remote-controlled anti-theft valve for uncontrolled blocks in overseas oil fields, enabling remote control of key oil well equipment.

[0005] To achieve the above objectives, embodiments of the present invention provide an oil well system with a remotely controlled anti-theft valve for uncontrolled blocks in overseas oil fields, comprising: Control module; A wireless communication module, which is connected to the control module; A remote terminal, which is capable of issuing remote control commands and transmitting them to the control module via the wireless communication module; The valve, which is a solenoid valve, is installed at the wellhead of the oil well and is electrically connected to the control module for remote control of its start and stop. A monitoring and early warning unit is used to collect status data at the oil well site and is electrically connected to the control module. An anti-theft protection assembly, comprising a housing structure that encloses the wireless communication module, the control module, the monitoring and early warning unit, and the valve.

[0007] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, wherein the monitoring and early warning unit includes: A vibration alarm, which is electrically connected to the control module, is used to collect vibration data at the oil well site and generate an alarm signal when the vibration data exceeds a preset vibration threshold. The pressure monitoring component includes a wellhead pressure sensor and a downhole casing pressure sensor. The wellhead pressure sensor is installed at the wellhead valve to collect wellhead pressure data, and the downhole casing pressure sensor is installed inside the downhole casing to collect downhole pressure data. Both the wellhead pressure sensor and the downhole casing pressure sensor are electrically connected to the control module.

[0008] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field. The anti-theft protection assembly further includes an anti-blast structure connected between the bottom of the valve and the wellhead. The anti-blast structure includes: A ring body, the ring body being connected to the bottom of the valve, having a channel communicating with the bottom of the valve; A sealing plate, which is slidably disposed on the ring body and has a closed state and an open state; A first elastic element, one end of which acts on the sealing plate to provide a force for the sealing plate to be in a closed state; A vibratory breaking plate is disposed on the ring body. The sealing plate has a breaking part that abuts against the vibratory breaking plate and restricts the sealing plate to an open state. After the vibratory breaking plate and the breaking part vibrate, the vibratory breaking plate can be broken, thereby changing the sealing plate from an open state to a closed state.

[0009] For example, at least one embodiment of this disclosure provides an oil well system with a remote-controlled anti-theft valve for an uncontrolled block in an overseas oil field, wherein the sealing plates are two symmetrically arranged, and the two sealing plates together block the channel.

[0010] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, which further includes a locking assembly for locking one end of the two sealing plates that are close together. The locking assembly includes: A socket and a plug are respectively disposed on the two sealing plates, and the plug is used to be inserted into the socket; The locking groove is formed on the inner wall of the socket and is perpendicular to the socket. The locking block is slidably disposed on the plug and the sliding direction is perpendicular to the plug, and is used to lock in the locking groove.

[0011] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, wherein the interlocking assembly further includes: The second elastic element has one end acting on the locking block and the other end acting on the plug, and is used to provide a force for the locking block to be engaged in the locking groove.

[0012] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field. The locking block has a first chamfer at one end near the insertion hole, and the insertion hole has a second chamfer. Both the first and second chamfers are used to guide the locking block to slide.

[0013] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, which further includes a power storage component. The power storage component is used for storing power in the first elastic element, including: A sliding member is slidably disposed on one side of the first elastic member and abuts against the other end of the first elastic member; A first pawl is slidably disposed on the slider; The first ratchet is disposed on the ring body, and the first pawl can be engaged on the first ratchet, so that the sliding member can only move towards the first elastic member after vibration; A third elastic element, one end of which acts on the first pawl and the other end of which acts on the sliding element, provides a force for the first pawl to engage with the first ratchet.

[0014] For example, at least one embodiment of this disclosure provides an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, which further includes an anti-opening component. The anti-opening component is used to prevent the sealing plate from changing from a closed state to an open state, including: The second pawl is slidably disposed on the sealing plate; The second ratchet is disposed on the ring body, and the second pawl can be engaged on the second ratchet, so that the sealing plate can only move in the direction of becoming closed. The fourth elastic element has one end acting on the second pawl and the other end acting on the sealing plate, providing a force for the second pawl to engage with the second ratchet.

[0023] Please see Figures 1-2 This invention illustrates an oil well system with a remotely controlled anti-theft valve for an uncontrolled block in an overseas oil field, according to an embodiment of the present invention. The system includes a control module 100, a wireless communication module 200, a remote terminal 300, a valve 400, a monitoring and early warning unit 500, and an anti-theft protection assembly 600. The control module 100 is connected to the valve 400, and the wireless communication module 200 is also connected to the control module 100. The remote terminal 300 can issue remote control commands, which are transmitted to the control module 100 via the wireless communication module 200. The valve 400 is a solenoid valve installed at the wellhead and electrically connected to the control module 100 for remote control of its start and stop. The monitoring and early warning unit 500 is used to collect status data from the oil well site and is electrically connected to the control module 100. The anti-theft protection assembly 600 includes a housing structure 601 that encloses the wireless communication module 200, the control module 100, the monitoring and early warning unit 500, and the valve 400. It may also include a pumping unit or a downhole blowout preventer 700, which is electrically connected to the control module 100 for remote control to start and stop.

[0024] The monitoring and early warning unit 500 includes a vibration alarm 510 and a pressure monitoring component 520. The vibration alarm 510 is electrically connected to the control module 100 and is used to collect vibration data at the oil well site. When the vibration data exceeds a preset vibration threshold, an alarm signal is generated. The pressure monitoring component 520 includes a wellhead pressure sensor 521 and a downhole casing pressure sensor 522. The wellhead pressure sensor 521 is installed at the wellhead valve and is used to collect wellhead pressure data. The downhole casing pressure sensor 522 is installed inside the downhole casing and is used to collect downhole pressure data. Both the wellhead pressure sensor 521 and the downhole casing pressure sensor 522 are electrically connected to the control module 100.

[0025] For example, the control module 100 uses a microcontroller chip as its core, such as an ARM series microcontroller. Around the core chip, a power management circuit is designed to ensure a stable and reliable power supply for the control module 100. The communication interface circuit is used to exchange data with the wireless communication module 200, the monitoring and early warning unit 500, the valve 400, the pumping unit, or the downhole blowout preventer 700. The storage circuit is used to store the system's configuration parameters, historical data, and control programs.

[0026] The control module 100 is responsible for coordinating the operation of various components. It receives remote control commands from the wireless communication module 200 and controls the start / stop of valves 400, pumping units, or downhole blowout preventers 700 accordingly. Simultaneously, it collects real-time well site status data from the monitoring and early warning unit 500, such as vibration data and wellhead and downhole pressure data, and analyzes and processes this data. When abnormal data is detected, the control module 100 judges according to preset rules, triggers the corresponding alarm mechanism, and sends the alarm information to the remote terminal 300 via the wireless communication module 200. Furthermore, the control module 100 is also responsible for configuring and managing various system parameters to ensure stable system operation.

[0027] The wireless communication module 200 uses an industrial-grade wireless communication module suitable for the harsh environment of oil wells, such as a module supporting 4G / 5G network communication, to ensure stable and high-speed data transmission in remote oilfield areas. The module integrates an antenna, RF transceiver circuitry, and baseband processing circuitry. The antenna employs a high-gain, anti-interference design, enabling effective signal reception and transmission in complex electromagnetic environments. The RF transceiver circuitry is responsible for converting baseband signals into RF signals for transmission and converting received RF signals back into baseband signals for processing. The baseband processing circuitry performs encoding, decoding, modulation, and demodulation operations on the baseband signals to achieve data interaction with the control module 100.

[0028] The wireless communication module 200 establishes a data bridge between the remote terminal 300 and the control module 100. It receives remote control commands from the remote terminal 300 and accurately transmits them to the control module 100. Simultaneously, it transmits real-time data from the control module 100, such as the well valve opening / closing status, on-site vibration data, wellhead and downhole pressure data, and alarm information, to the remote terminal 300, enabling real-time monitoring and remote control of the oil well site.

[0029] The remote terminal 300 consists of a remote management platform and a mobile phone terminal. The remote management platform is typically deployed in the oil company's data center or cloud server, employing high-performance server hardware and professional monitoring and management software. The server hardware possesses powerful computing and storage capabilities, capable of processing large amounts of oil well data and providing services to multiple users. The monitoring and management software features a user-friendly visual interface, intuitively displaying oil well valve opening and closing status, on-site vibration data, wellhead and downhole pressure data, alarm information, etc., through charts and graphs. The software also has access control functionality, with different levels of users having different operating permissions to ensure system security. The mobile phone terminal is an application developed based on a smartphone platform, synchronizing data with the remote management platform via the network. The mobile application also has a visual interface, allowing oil company managers and technicians to monitor and control oil wells anytime, anywhere.

[0030] The Remote Terminal 300 provides oil company personnel with a convenient means of remote monitoring and control. Staff can view the operational status of oil wells in real time through a remote management platform or mobile terminal. When an anomaly is detected, they can promptly issue remote control commands for valve opening / closing and linkage equipment control through a visual display interface, enabling remote operation of the oil well. Simultaneously, the Remote Terminal 300 can store, query, and analyze historical data, providing data support for corporate decision-making, helping companies better manage oil well production, and reduce risks.

[0031] Valve 400 employs a solenoid valve, with its body made of high-strength, corrosion-resistant alloy materials such as stainless steel or Hastelloy to withstand the harsh working environment of the oil wellhead. The internal solenoid coil is encapsulated in high-temperature resistant, moisture-proof insulating material to ensure it will not be damaged by high temperatures or humidity during long-term operation. The valve core is manufactured using precision machining, providing excellent sealing and reliability, and accurately controlling the flow of oil. Valve 400 connects securely to the wellhead pipeline to prevent leakage.

[0032] Valve 400, as an actuator in the oil well system, is used for remote control of its start and stop. When control module 100 receives an opening command from remote terminal 300, control module 100 energizes the solenoid coil of valve 400. The electromagnetic force drives the valve core to open, allowing crude oil to flow out of the well smoothly. Conversely, when a closing command is received, control module 100 cuts off the power to the solenoid coil, and the valve core closes under the action of spring force or gravity, preventing crude oil from flowing out. This enables remote control of oil well production and effectively prevents the plundering of resources in uncontrolled blocks of overseas oil fields.

[0033] The vibration alarm 510 uses an accelerometer as its core detection element, enabling sensitive detection of minute vibrations at the oil well site. The accelerometer is securely mounted on a structure near the wellhead using a dedicated mounting bracket, ensuring accurate acquisition of vibration data. Based on the accelerometer, a signal amplification circuit, a filtering circuit, and a microprocessor circuit are designed. The signal amplification circuit amplifies the weak electrical signal output from the accelerometer, the filtering circuit removes noise interference from the signal, and the microprocessor circuit analyzes and judges the processed signal. When the vibration data exceeds a preset vibration threshold, the microprocessor circuit generates an alarm signal and sends it to the control module 100 via an electrical connection. The housing of the vibration alarm 510 is made of high-strength, waterproof, and dustproof materials to withstand the harsh environmental conditions at the oil well site.

[0034] The vibration alarm 510 collects vibration data from the oil well site in real time. When abnormal vibration is detected, such as unauthorized dismantling of wellhead equipment or an earthquake, the vibration data will exceed the preset vibration threshold. At this time, the vibration alarm 510 generates an alarm signal and sends it to the control module 100. After receiving the alarm signal, the control module 100, on the one hand, sends the alarm information to the remote terminal 300 through the wireless communication module 200 to notify relevant personnel to handle the situation in a timely manner; on the other hand, the control module 100 can take corresponding measures according to preset rules, such as closing the valve 400 to prevent equipment damage and resource loss.

[0035] The wellhead pressure sensor 521 employs a pressure-sensitive element, such as a piezoresistive pressure sensor, to accurately measure the pressure at the wellhead valve. The pressure-sensitive element is encapsulated in a robust stainless steel housing with a mounting interface adapted to the wellhead valve, allowing for installation at the valve via threaded or flanged connections. The sensor integrates a signal conditioning circuit that amplifies, filters, and linearizes the electrical signal output from the pressure-sensitive element before transmitting the processed pressure data to the control module 100 via an electrical connection. The wellhead pressure sensor 521 features high accuracy, high reliability, and excellent anti-interference capabilities, enabling stable operation in the complex environment of an oil wellhead.

[0036] The downhole casing pressure sensor 522 is designed for installation inside the downhole casing to monitor downhole pressure data in real time. It features a high-pressure and corrosion-resistant design, capable of withstanding the harsh downhole working environment. The sensor's pressure detection section utilizes a high-performance pressure-sensitive chip, sealed within a pressure- and corrosion-resistant housing using a special encapsulation process. The housing has a mounting structure compatible with the casing for easy installation and fixation. The downhole casing pressure sensor 522 also integrates signal conditioning circuitry, processing the pressure signal before transmitting the pressure data to the control module 100 via cable. The high-precision measurement of the downhole casing pressure sensor 522 provides crucial data support for oil well production management, helping operators understand downhole pressure changes and promptly identify potential problems.

[0037] The pressure monitoring component 520 collects wellhead pressure data and downhole pressure data through the wellhead pressure sensor 521 and the downhole casing pressure sensor 522, respectively, and transmits these data to the control module 100 in real time. The control module 100 analyzes and processes the pressure data. When abnormal pressure data occurs, such as excessively high or low wellhead pressure or sudden changes in downhole pressure, the control module 100 determines that there may be a production failure or safety hazard in the oil well. It then sends an alarm message to the remote terminal 300 through the wireless communication module 200 to remind the staff to take timely measures to ensure the safe and stable production of the oil well.

[0038] The housing structure 601 of the anti-theft protection assembly 600 is made of high-strength alloy steel or carbon fiber composite material. The housing structure 601 tightly encloses the core electrical components and valve actuators of the device, including the wireless communication module 200, control module 100, monitoring and early warning unit 500, and valve 400. The various parts of the housing are fixed together using special connection methods, such as high-strength bolts, with anti-disassembly sealing structures at the joints to prevent unauthorized personnel from damaging or replacing internal components by removing the bolts. Warning signs can be placed on the surface of the housing to indicate that the device is protected and unauthorized disassembly is prohibited. Simultaneously, anti-theft alarm devices, such as microswitches or infrared sensors, can be installed inside the housing. When the housing is illegally opened, an alarm signal is triggered, and the alarm information is sent to the remote terminal 300 via the control module 100 and wireless communication module 200.

[0039] The Anti-theft Protection Assembly 600 provides reliable physical protection for the core components of oil well systems. It prevents unauthorized disassembly, damage, and replacement of equipment, protecting the integrity and safety of the system. Even in uncontrolled blocks of overseas oil fields, facing malicious acts from partners, the Anti-theft Protection Assembly 600 can, to a certain extent, prevent damage and theft of critical equipment, ensuring the normal operation of the oil well system and reducing economic losses for oil companies.

[0040] For non-flowing wells, there is usually a pumping unit. The pumping unit can be remotely started and stopped through the control module 100 according to different well requirements. At the same time, some sensors, such as current sensors and temperature sensors, can be installed on the pumping unit to monitor the operating status of the pumping unit and transmit the data to the control module 100.

[0041] Downhole blowout preventers (BOPs) typically employ gate-type BOPs or annular BOPs. Taking a gate-type BOP as an example, it mainly consists of a housing, gate, seals, and a hydraulic control system. The housing is installed between the wellhead and the downhole casing, while the gate is located inside the housing. The hydraulic control system controls the opening and closing of the gate. When the downhole pressure abnormally increases, potentially leading to a blowout, the hydraulic control system drives the gate to close, sealing the annular space between the wellhead and the casing to prevent the ejection of fluids such as oil, gas, and water. The downhole BOP is remotely controlled to start and stop via a control module 100 and is equipped with monitoring devices such as pressure sensors to monitor downhole pressure in real time and transmit the data to the control module 100.

[0042] The pumping unit is electrically connected to the control module 100 and can be remotely controlled to start and stop. When the remote terminal 300 sends a start command, the control module 100 controls the power equipment of the pumping unit to start, and the pumping unit begins to work, extracting crude oil from the well. By remotely controlling the start and stop of the pumping unit, the pumping operation can be flexibly adjusted according to factors such as the production status of the oil well and market demand, thereby improving production efficiency. At the same time, in uncontrolled blocks of overseas oil fields, it can prevent the unreasonable exploitation of resources.

[0043] For flowing wells, the downhole blowout preventer is electrically connected to the control module 100 and can be remotely controlled to start and stop. When the monitoring and early warning unit 500 detects an abnormal increase in downhole pressure, indicating a possible blowout, the control module 100 promptly issues instructions according to preset rules to activate the downhole blowout preventer, close the gate or annular seal, prevent a blowout, ensure the safety of oil well equipment and personnel, and reduce potential environmental hazards.

[0044] After the oil well system is installed and commissioned, all components enter normal working condition. The control module 100 collects real-time oil well site status data from the monitoring and early warning unit 500, including vibration data collected by the vibration alarm 510, wellhead pressure data collected by the wellhead pressure sensor 521, and downhole pressure data collected by the downhole casing pressure sensor 522.

[0045] The wireless communication module 200 maintains a connection with the remote terminal 300, transmitting in real-time data collected by the control module 100, such as the opening and closing status of oil well valves, on-site vibration data, and wellhead and downhole pressure data, to the remote terminal 300. The remote terminal 300's visual display interface shows this data in real time, allowing oil company personnel to easily monitor the well's operational status.

[0046] Valve 400 is in normal opening and closing control state. According to the needs of oil well production, the staff issues valve opening and closing commands through remote terminal 300. Wireless communication module 200 transmits the commands to control module 100. Control module 100 controls the opening or closing of valve 400 according to the commands to realize the control of oil well production.

[0047] For non-flowing wells, the pumping unit is started and stopped by the control module 100 according to the instructions issued by the remote terminal 300 to carry out normal pumping operations; for flowing wells, the downhole blowout preventer is in standby mode, monitoring the downhole pressure in real time and preparing to deal with possible blowout accidents.

[0048] When the vibration alarm 510 detects that the vibration data at the oil well site exceeds the preset vibration threshold, such as when someone illegally dismantles the wellhead equipment, the vibration alarm 510 generates an alarm signal and sends it to the control module 100. Upon receiving the alarm signal, the control module 100, on the one hand, sends the alarm information to the remote terminal 300 via the wireless communication module 200, and an alarm prompt pops up on the visual display interface of the remote terminal 300 to notify relevant personnel to handle the situation promptly; on the other hand, the control module 100 can immediately close the valve 400 according to preset rules to prevent equipment damage and resource loss. Simultaneously, the control module 100 can also activate corresponding protective measures of the pumping unit or the downhole blowout preventer 700, such as stopping the pumping unit or preparing to activate the downhole blowout preventer.

[0049] When abnormalities occur in the wellhead pressure data collected by the wellhead pressure sensor 521 or the downhole pressure data collected by the downhole casing pressure sensor 522, such as excessively high or low wellhead pressure or sudden changes in downhole pressure, the control module 100 determines that there may be a production failure or safety hazard in the oil well. The control module 100 sends alarm information to the remote terminal 300 via the wireless communication module 200, highlighting the abnormal pressure data and alarm prompts on the visual display interface of the remote terminal 300. Based on the alarm information and real-time data, the operator issues corresponding commands through the remote terminal 300, such as adjusting valve opening, starting or stopping the pumping unit, or the downhole blowout preventer. The control module 100 receives and executes these commands to ensure the safe and stable production of the oil well.

[0050] Oil company staff can view real-time operating status data of oil wells through a visual display interface on a remote terminal 300. When remote control of the oil well is required, such as adjusting the oil production, starting or stopping the pumping unit, or the downhole blowout preventer, staff can input the corresponding remote control commands on the remote terminal 300.

[0051] The remote terminal 300 sends remote control commands to the wireless communication module 200 via the network. After receiving the commands, the wireless communication module 200 transmits them to the control module 100.

[0052] The control module 100 parses and verifies the received remote control commands to ensure their legality and accuracy. Upon successful verification, the control module 100 controls the valve 400, pumping unit, or downhole blowout preventer 700 to perform the corresponding operations. Simultaneously, the control module 100 feeds back the command execution results to the remote terminal 300 via the wireless communication module 200. The remote terminal 300's visual display interface updates the well equipment status in real time, allowing personnel to confirm the success of the operation.

[0053] By remotely controlling valve 400 through remote terminal 300, wireless communication module 200 and control module 100, oil companies can quickly shut off wellhead valves in uncontrolled blocks of overseas oil fields, effectively preventing the forced plunder of oil and gas resources, reducing resource losses and safeguarding the legitimate rights and interests of the company.

[0054] The pumping unit or downhole blowout preventer 700 is electrically connected to the control module 100 and can be remotely controlled to start and stop, enabling enterprises to have comprehensive management and control over oil well production equipment. For example, in the event of a loss of control, the pumping unit operation can be stopped in time to prevent the unreasonable exploitation of resources; when a blowout is possible in a flowing well, the downhole blowout preventer can be remotely activated to ensure the safety of the oil well and further protect oil and gas resources.

[0055] The vibration alarm 510 in the monitoring and early warning unit 500 monitors the vibration data of the oil well site in real time, and the pressure monitoring component 520 collects the pressure data at the wellhead and downhole in real time. Once an abnormality occurs, it can generate an alarm signal in a timely manner, which is transmitted to the remote terminal 300 through the control module 100 and the wireless communication module 200, notifying the staff to take measures to prevent safety accidents, such as preventing safety hazards caused by illegal disassembly of equipment, and accidents such as blowouts caused by abnormal pressure.

[0056] The anti-theft protection assembly 600 adopts a high-strength, damage-resistant shell structure 601, which tightly covers key equipment to prevent the device from being illegally disassembled, damaged, or replaced. It provides physical protection for the safety and stability of the oil well system, ensuring that the equipment can operate normally in complex and dangerous overseas environments and reducing safety risks.

[0057] Both the remote management platform and mobile terminal of the Remote Terminal 300 are equipped with visual display interfaces, which display the real-time status of oil well valves, on-site vibration data, wellhead and downhole pressure data, alarm information, etc. Staff can monitor the oil well's operating status anytime, anywhere through these terminals and issue remote control commands for valve opening / closing and linkage equipment control, achieving efficient oil well management and saving manpower and time costs.

[0058] This oil well system is compatible with the wellheads of normal production wells, long-term shutdown wells, flowing wells, and experimental wells in oil fields. Regardless of the production status or type of the oil well, the system can effectively control valves remotely, protect assets, and manage the risk of loss of control. This improves the system's versatility and applicability, and facilitates unified management of various types of oil wells by enterprises.

[0059] In some examples, please refer to Figures 2-4 The anti-theft protection assembly 600 also includes an anti-blast structure 610, which is connected between the bottom of the valve 400 and the wellhead. The anti-blast structure 610 includes a ring body 611, a sealing plate 612, a first elastic element 613, and a vibration-breaking plate 614. The ring body 611 is connected to the bottom of the valve 400 and has a channel 6111 that communicates with the bottom of the valve body. The sealing plate 612 is slidably disposed on the ring body 611 and has a closed state and an open state. An elastic element 613 acts on one end of a sealing plate 612, providing a force to keep the sealing plate 612 in a closed state. A vibrating shattering plate 614 is disposed on the ring body 611. The sealing plate 612 has a breaking part 6121, which abuts against the vibrating shattering plate 614 and restricts the sealing plate 612 to an open state. After the vibrating shattering plate 614 and the breaking part 6121 vibrate, the vibrating shattering plate 614 can be broken, thereby changing the sealing plate 612 from an open state to a closed state.

[0060] For example, the ring body 611 is circular in shape and is integrally formed at the bottom of the valve 400. The channel 6111 runs through the axial direction of the ring body 611 and is circular in shape. It is connected to the oil outlet at the bottom of the valve body to ensure that the oil flow can pass smoothly.

[0061] The ring body 611, as the basic support component of the anti-riot structure 610, not only provides installation positions for the sealing plate 612, the first elastic element 613, and the vibration fracture plate 614, but also connects the valve 400 to the wellhead, ensuring the normal delivery path of the oil flow. At the same time, its high-strength structural design can withstand a certain degree of external violent impact, protecting internal components from damage.

[0062] The sealing plate 612 is made of metal, such as stainless steel, which has good corrosion resistance and mechanical strength. The shape of the sealing plate 612 matches the channel 6111 of the ring body 611, and is also circular, with its size slightly larger than the opening of the channel 6111 to ensure complete blockage of oil flow in the closed state. One side of the sealing plate 612 is provided with a groove that matches the slide rail on the ring body 611, allowing the sealing plate 612 to slide laterally on the ring body 611. A breaking part 6121 is located on the side of the sealing plate 612 near the vibrating breaking plate 614. The breaking part 6121 can be a protruding sharp corner or edge structure, and its material hardness is higher than that of the vibrating breaking plate 614, so that it can effectively break the vibrating breaking plate 614 during vibration.

[0063] The sealing plate 612 functions to close and open the channel 6111 through sliding. Under normal use, the sealing plate 612 is in the open state under the constraint of the vibrating shattering plate 614, allowing oil flow through the channel 6111. In the event of violent disassembly, after the vibrating shattering plate 614 breaks, the sealing plate 612 quickly slides to the closed state under the action of the first elastic element 613, blocking the oil flow and preventing leakage of oil and gas resources during illegal disassembly. Simultaneously, it prevents unauthorized personnel from continuing to operate the valve 400, thus serving as an anti-theft control measure.

[0064] The first elastic element 613 is a compression spring, with one end fixed to a fixed seat on the ring 611 and the other end acting on the side of the sealing plate 612. The compression deformation of the spring provides a continuous thrust to the sealing plate 612. To ensure the stability of the spring during operation, a guide rod can be installed inside the spring. One end of the guide rod is fixed to the fixed seat, and the other end passes through the side of the sealing plate 612 to prevent the spring from tilting or shifting during compression and extension.

[0065] The first elastic element 613 is the power source for the automatic closing of the sealing plate 612. Under normal conditions, although the spring is compressed, the sealing plate 612 remains open due to the restriction of the vibrating shattering plate 614 on the sealing plate 612. When the vibrating shattering plate 614 breaks, the spring releases its elastic force, pushing the sealing plate 612 to slide rapidly, closing the channel 6111 and achieving the functions of preventing tampering and stopping oil flow. At the same time, the elasticity of the first elastic element 613 can also buffer the impact force generated by the rapid sliding of the sealing plate 612 to a certain extent, protecting the sealing plate 612 and the ring 611 from damage.

[0066] The vibratory crushing plate 614 is made of glass or a similar brittle material, such as ceramic plate. Its shape is adapted to the pre-reserved installation position on the ring body 611, and is generally circular or square. The thickness of the vibratory crushing plate 614 is selected according to actual needs. It must be able to withstand a certain amount of external force during normal use to block the breaking part 6121 of the sealing plate 612, and also be easy to break when subjected to vibration caused by violent disassembly. The vibratory crushing plate 614 is fixed to the ring body 611 by a special installation structure, such as by adhesive, snap-fit, or bolt fixing. However, it must be ensured that it can break smoothly during vibration, and that the crushing effect is not affected by overly tight fixing.

[0067] Under normal circumstances, the vibrating breaker plate 614 restricts the position of the sealing plate 612, keeping it open and ensuring normal oil flow. However, when subjected to violent dismantling, such as when unauthorized personnel use tools to strike or vibrate the valve 400, the vibrating breaker plate 614 and the breaking part 6121 will vibrate. Due to the brittle nature of its material, the vibrating breaker plate 614 will break, thereby releasing the restriction on the sealing plate 612. This triggers the sealing plate 612 to close the channel 6111 under the action of the first elastic element 613, achieving the anti-tampering function.

[0068] During normal operation of the oil well system, the sealing plate 612, blocked by the vibratory fracture plate 614, overcomes the elastic force of the first elastic element 613 and remains in the open position. Oil flows out from the bottom of the valve 400, passes through the channel 6111 of the ring body 611, and is smoothly delivered to the subsequent pipeline. The first elastic element 613 is in a compressed state, and the vibratory fracture plate 614 is firmly fixed on the ring body 611, abutting against the breaking part 6121 of the sealing plate 612, maintaining the open position of the sealing plate 612, and ensuring normal oil production from the oil well.

[0069] When unauthorized personnel forcibly dismantle valve 400, such as by striking valve 400 with tools or attempting to forcibly remove ring 611, it will cause vibration of the entire anti-riot structure 610.

[0070] The vibration is transmitted to the breaking part 6121 of the vibratory breaking plate 614 and the sealing plate 612. Since the vibratory breaking plate 614 is made of glass or a similar brittle material, under the action of vibration, the vibratory breaking plate 614 will gradually develop cracks and eventually break.

[0071] After the vibrating shattering plate 614 breaks, the restriction on the sealing plate 612 is released, and the first elastic element 613 releases the stored elastic potential energy, pushing the sealing plate 612 to slide rapidly along the slide rail on the ring body 611, thus closing the channel 6111.

[0072] After sealing the channel 6111 with plate 612, the continued delivery of oil flow was stopped, and at the same time, it prevented unauthorized personnel from directly operating valve 400, effectively preventing the leakage of oil and gas resources and illegal mining, and achieving the function of preventing riot control.

[0073] When subjected to violent dismantling, the anti-riot structure 610 can automatically trigger the sealing plate 612 to close the channel 6111, actively blocking the oil flow and preventing oil and gas resources from being plundered during illegal dismantling. Compared with traditional passive protection methods, it enhances the protection capability of oil well resources.

[0074] After the sealing plate 612 is closed, it not only blocks the oil flow, but also seals the bottom of valve 400, making it difficult for unauthorized personnel to continue operating the valve. This further improves the anti-theft and control effect and protects the legitimate rights and interests of oil companies in uncontrolled blocks of overseas oil fields.

[0075] In cases where violent disassembly may damage the valve and cause oil and gas leaks, the anti-riot disassembly structure 610 can quickly seal the passage 6111, effectively preventing oil and gas leaks, reducing the risk of safety accidents such as fires and explosions caused by oil and gas leaks, and ensuring the safety of personnel and equipment at the oil well site.

[0076] Dual protection of physical and functional aspects: Combining the high-strength, damage-resistant shell structure 601 of the anti-theft protection assembly 600 with the anti-explosion structure 610, the oil well system is provided with more comprehensive security from both physical protection and functional blocking levels, enhancing the system's reliability in complex and dangerous environments.

[0077] The components of the explosion-proof structure 610 are relatively simple, using common materials and mature mechanical structures, making it easy to manufacture, install, and maintain. This simple yet effective design allows the structure to be easily adapted to various types of valves 400 and wellheads, improving the versatility and adaptability of the entire oil well system.

[0078] The 610 anti-riot structure does not affect the normal production process of the oil well under normal working conditions. It provides protection in a non-invasive manner, ensuring the production efficiency of the oil well while being ready to deal with possible violent dismantling situations, thus achieving a good balance between production and protection.

[0079] In some examples, two symmetrically arranged sealing plates 612 together block the channel 6111. A locking assembly 620 is also included, which locks the two sealing plates 612 at their closest points. The locking assembly 620 includes a socket 621, a plug 622, a locking groove 623, a locking block 624, and a second elastic member 625. The socket 621 and plug 622 are respectively disposed on the two sealing plates 612, and the plug 622 is inserted into the socket 621. The locking groove 623 is formed on the inner wall of the socket 621 and is perpendicular to the socket 621. The locking block 624 is slidably disposed on the plug, with its sliding direction perpendicular to the plug 622, and is used to engage within the locking groove 623. One end of the second elastic member 625 acts on the locking block 624, and the other end acts on the plug 622, providing force for the locking block 624 to engage within the locking groove 623. The locking block 624 has a first chamfer 6241 at the end near the socket 621, and the socket 621 has a second chamfer 6211. Both the first chamfer 6241 and the second chamfer 6211 are used to guide the locking block 624 to slide.

[0080] For example, two sealing plates 612 are symmetrically arranged, which together completely block the channel 6111 when closed. Each sealing plate 612 has a groove on one side that matches the slide rail on the ring 611, allowing the sealing plate 612 to slide laterally on the ring 611. The breaking part 6121 is also provided on the side of the sealing plate 612 near the vibrating breaking plate 614.

[0081] The two symmetrically arranged sealing plates 612 provide better sealing and stability when closing the channel 6111 compared to a single sealing plate. Under normal operating conditions, the two sealing plates 612 remain open under the constraint of the vibratory fracture plate 614, allowing oil to flow through the channel 6111. When the vibratory fracture plate 614 breaks, the two sealing plates 612 simultaneously slide towards the center of the channel 6111 under the action of the first elastic element 613, jointly sealing the channel 6111, effectively preventing oil flow and improving the reliability of the anti-explosive structure 610.

[0082] The locking assembly 620 has a socket 621 and a plug 622, which are respectively located at opposite ends of the two sealing plates 612. The socket 621 is a cylinder with a certain depth, and its inner diameter matches the outer diameter of the plug 622 to ensure that the plug 622 can be tightly inserted. The plug 622 corresponds to the socket 621 in shape and is cylindrical, with its length slightly less than the depth of the socket 621 to ensure that there is some room for movement after insertion.

[0083] The socket 621 and the plug 622 constitute the basic connection structure of the locking assembly 620. When the two sealing plates 612 slide toward the center of the channel 6111 under the action of the first elastic member 613, the plug 622 is inserted into the socket 621, initially realizing the connection between the two sealing plates 612, and providing a foundation for the subsequent locking structure.

[0084] A locking groove 623 is formed on the inner wall of the socket 621 and is perpendicular to the socket 621. A locking block 624 is slidably disposed on the plug 622, and its sliding direction is perpendicular to the axial direction of the plug 622.

[0085] When the plug 622 is inserted into the socket 621, the locking block 624, under the action of the second elastic element 625, slides into the locking groove 623 and engages therein, thereby firmly locking the two sealing plates 612 together. This locking structure can prevent the two sealing plates 612 from separating under oil flow pressure or external vibration, ensuring that the channel 6111 is always in a closed state, further enhancing the reliability of the anti-tamper structure 610.

[0086] The second elastic element 625 is a compression spring, ensuring sufficient force to keep the locking block 624 firmly locked in the locking groove 623. One end of the spring is fixed to the mounting base on the plug 622, and the other end acts on the side of the locking block 624, providing a continuous thrust to the locking block 624 through the compression deformation of the spring.

[0087] The second elastic element 625 provides a continuous clamping force to the locking block 624, which is key to the reliable locking of the locking assembly 620. After the plug 622 is inserted into the socket 621, the second elastic element 625 pushes the locking block 624 to quickly engage with the locking groove 623, forming a strong locking structure. This ensures the connection between the locking block 624 and the locking groove 623, preventing the two sealing plates 612 from separating. Even if unauthorized personnel want to break the locking connection of the sealing plates 612, it will be difficult for them to do so.

[0088] The locking block 624 has a first chamfer 6241 at the end near the insertion hole 621, and a second chamfer 6211 at the entrance of the insertion hole 621. The specific angles are designed according to the actual situation to ensure a good fit between the two. The chamfer design aims to guide the locking block 624 to slide smoothly during insertion and reduce insertion resistance.

[0089] The first chamfer 6241 and the second chamfer 6211 serve to guide and direct the plug 622 as it is inserted into the socket 621. When the plug 622 approaches the socket 621, the first chamfer 6241 and the second chamfer 6211 cooperate to guide the locking block 624 smoothly into the locking groove 623, avoiding locking failure due to insertion angle deviation or excessive resistance, thus improving the ease of operation and reliability of the locking assembly 620.

[0090] When the vibratory break plate 614 breaks under the vibration caused by violent disassembly, the first elastic element 613 releases its elastic potential energy, pushing the two symmetrically arranged sealing plates 612 to slide along the slide rail on the ring body 611 towards the center of the channel 6111. As the sealing plates 612 slide, the plugs 622 located at opposite ends of the two sealing plates 612 gradually approach the sockets 621. When the plugs 622 are aligned with the sockets 621, the plugs 622 begin to insert into the sockets 621, achieving the initial connection between the two sealing plates 612.

[0091] During the process of inserting the plug 622 into the socket 621, the locking block 624 slides towards the locking groove 623 under the elastic force of the second elastic member 625.

[0092] Guided by the first chamfer 6241 and the second chamfer 6211, the locking block 624 smoothly engages in the locking groove 623. At this time, the second elastic element 625 is in a compressed state, continuously providing elastic force, which keeps the locking block 624 tightly engaged in the locking groove 623, firmly locking the two sealing plates 612 together, ensuring that the channel 6111 is reliably blocked and preventing unauthorized operation.

[0093] Due to the function of the locking assembly 620, the two sealing plates 612 are always tightly connected, the channel 6111 remains closed and cannot be opened or used. The clamping force continuously provided by the second elastic element 625 ensures that the locking block 624 and the locking groove 623 maintain a tight fit, effectively resisting the damage to the connection of the sealing plates 612 by various external forces, and ensuring the long-term stable operation of the anti-explosive structure 610.

[0094] The locking assembly 620 securely connects two symmetrically arranged sealing plates 612 together through the synergistic action of the socket 621, plug 622, locking groove 623, locking block 624, and second elastic element 625. This robust connection effectively prevents the sealing plates 612 from separating due to external forces during violent dismantling or complex oil well conditions, ensuring that the channel 6111 remains closed at all times, further enhancing the ability of the anti-riot structure 610 to prevent oil and gas leaks and illegal operations.

[0095] The continuous clamping force provided by the second elastic element 625, along with the guiding effect of the first chamfer 6241 and the second chamfer 6211, makes the locking process of the locking assembly 620 more reliable and smooth. Even in emergency situations, such as rapid forced disassembly causing the sealing plate 612 to slide and connect quickly, the locking assembly 620 can ensure that the two sealing plates 612 are quickly and firmly locked together, improving the reliability of the tamper-proof structure 610 under various complex conditions.

[0096] During actual operation of the oil well, the locking assembly 620 can maintain a tight connection between the two sealing plates 612, ensuring the normal operation of the anti-explosion structure 610 and guaranteeing the safe and stable operation of the oil well.

[0097] The design of the first chamfer 6241 and the second chamfer 6211 makes the process of inserting the plug 622 into the socket 621 and the locking block 624 into the locking groove 623 smoother, reducing operational resistance and difficulty. This optimized operational performance not only ensures the smooth connection of the sealing plate 612 when the anti-explosion structure 610 is working normally, but also facilitates the disassembly and installation of the sealing plate 612 by staff during maintenance and repair, improving work efficiency.

[0098] The design of the locking assembly 620 ensures that the two sealing plates 612 can be quickly connected and locked after the vibration-damped plate 614 breaks. This rapid response capability enables the blast-resistant structure 610 to react to violent dismantling in the shortest possible time, promptly sealing the passage 6111, effectively preventing oil and gas leaks and illegal operations, and improving the emergency response performance of the blast-resistant structure 610.

[0099] In some examples, a power storage component 630 is also included. The power storage component 630 is used to store power for the first elastic member 613. It includes a slider 631, a first pawl 632, a first ratchet 633, and a third elastic member 634. The slider 631 is slidably disposed on one side of the first elastic member 613 and abuts against the other end of the first elastic member 613. The first pawl 632 is slidably disposed on the slider 631. The first ratchet 633 is disposed on the ring body 611. The first pawl 632 can be locked on the first ratchet 633, so that the slider 631 can only move towards the first elastic member 613 after vibration. One end of the third elastic member 634 acts on the first pawl 632 and the other end acts on the slider 631, providing the force for the first pawl 632 to lock on the first ratchet 633.

[0100] For example, the slider 631 is designed as a cuboid, with a groove on one side that matches the slide rail on the ring 611. Through this groove, the slider 631 can slide on the ring 611 in a direction parallel to the axis of the first elastic member 613. The end of the slider 631 that contacts the first elastic member 613 is designed as a plane or a structure that matches the shape of the end of the first elastic member 613, ensuring that force can be effectively transmitted between the two.

[0101] The sliding member 631 plays a role in transmitting force and storing energy in the energy storage assembly 630. When subjected to external vibration, the sliding member 631 slides on the ring 611, compressing the first elastic member 613 and causing the first elastic member 613 to store elastic potential energy. At the same time, due to the cooperation of the first pawl 632 and the first ratchet 633, the sliding member 631 can only move towards the first elastic member 613, thereby ensuring that the first elastic member 613 can continuously store force, providing a stronger sealing force for the sealing plate 612 when needed.

[0102] The first pawl 632 is made of high-strength metal, such as hardened alloy steel, to enhance its wear resistance and toughness. The first pawl 632 is shaped such that one end has a locking tooth that matches the ratchet teeth of the first pawl 633, and the other end is a connecting end for abutting against the third elastic element 634. The shape and size of the locking tooth correspond to the ratchet teeth of the first pawl 633 to ensure a tight engagement.

[0103] The first pawl 632 is a component that enables the unidirectional movement of the slider 631. When the slider 631 is vibrated and slides towards the first elastic member 613, the first pawl 632 moves together with the slider 631, and its teeth slide along the ratchet teeth of the first ratchet 633. When the slider 631 is subjected to a reverse force or stops sliding, under the action of the third elastic member 634, the teeth of the first pawl 632 are tightly engaged on the ratchet teeth of the first ratchet 633, preventing the slider 631 from moving in the opposite direction, thereby ensuring the stored force of the first elastic member 613, so that it can provide sufficient elasticity to the sealing plate 612 to close the channel 6111 when needed.

[0104] The first ratchet 633 is long and narrow, and its length is determined according to the maximum sliding stroke of the slider 631. A series of ratchet teeth are evenly distributed on the surface of the first ratchet 633. The ratchet teeth are right-angled triangles or trapezoids. The first ratchet 633 is vertically fixed to the ring 611 by bolts or welding to ensure that it is firmly installed and will not loosen during use.

[0105] The first ratchet 633 provides a one-way anti-reverse support structure for the first pawl 632. Cooperating with the first pawl 632, it ensures that the sliding member 631 can only move towards the first elastic member 613, allowing the first elastic member 613 to continuously store energy. Even under conditions such as violent disassembly, if the sliding member 631 is subjected to a large external impact, the tight engagement of the first ratchet 633 and the first pawl 632 can prevent the sliding member 631 from moving in the opposite direction, ensuring that the energy stored in the first elastic member 613 is not lost, and providing reliable power support for the closing of the sealing plate 612.

[0106] The third elastic element 634 is a compression spring, selected based on the actual installation space and required elastic force, to ensure sufficient force to tightly engage the first pawl 632 with the first ratchet 633. One end of the spring is fixed to the mounting base on the sliding element 631, and the other end acts on the connecting end of the first pawl 632, providing a continuous clamping force to the first pawl 632 through the compression deformation of the spring.

[0107] The third elastic element 634 provides a continuous clamping force to the first pawl 632, which is crucial for ensuring the unidirectional movement of the slider 631 and the continuous storage of force by the first elastic element 613. During the movement of the slider 631, the third elastic element 634 is in a certain compressed state, but it does not affect the sliding of the first pawl 632 on the first ratchet 633. When the slider 631 stops moving or is subjected to a reverse force, the third elastic element 634 releases its elasticity, pushing the teeth of the first pawl 632 to tightly engage between the teeth of the first ratchet 633, forming a reliable anti-reverse force to ensure that the slider 631 will not move in the opposite direction and to maintain the stored force state of the first elastic element 613.

[0108] When the wellhead of the oil well is subjected to violent dismantling or other reasons that cause vibration, the vibration is transmitted to the sliding member 631, causing it to slide along the slide rail on the ring body 611 toward the direction of the first elastic member 613.

[0109] During the sliding process, the slider 631 compresses the first elastic element 613, causing it to store elastic potential energy. Simultaneously, the first pawl 632 moves along with the slider 631, its teeth sliding upwards along the ratchet teeth of the first pawl 633. At this time, the third elastic element 634 is in a compressed state, but the elastic force it provides does not hinder the sliding of the first pawl 632.

[0110] As the slider 631 continues to slide, the first elastic element 613 is continuously compressed, and the stored elastic potential energy gradually increases.

[0111] When the slider 631 stops sliding or is subjected to a reverse force, the third elastic element 634 releases its compressive elastic force, pushing the teeth of the first pawl 632 to quickly engage with the teeth of the first ratchet 633. The tight engagement between the first pawl 632 and the first ratchet 633 forms a one-way anti-reverse structure, effectively preventing the slider 631 from moving in the opposite direction, thereby ensuring that the elastic potential energy stored in the first elastic element 613 is not lost due to the reverse movement of the slider 631.

[0112] When unauthorized personnel continue to cause damage, the third elastic element 634 accumulates more and more force, exceeding the bearing capacity of the vibrating shattering plate 614. The breaking part 6121 will then break the vibrating shattering plate 614. After the vibrating shattering plate 614 breaks, the sealing plate 612 loses its restraint. Under the action of the elastic potential energy stored in the first elastic element 613, the first elastic element 613 extends, pushing the sealing plate 612 to slide and close the channel 6111.

[0113] The energy storage assembly 630, through the coordinated action of the sliding member 631, the first pawl 632, the first ratchet 633, and the third elastic member 634, enables the first elastic member 613 to continuously store energy during the vibration generated by violent disassembly. Compared to ordinary elastic member settings, this ensures that the breaking part 6121 can break the vibration fracture plate 614 when subjected to violent damage, and that the vibration fracture plate 614 will not break during normal use.

[0114] The one-way anti-reverse structure composed of the first pawl 632 and the first ratchet 633, along with the continuous clamping force provided by the third elastic element 634, ensures that the energy stored in the first elastic element 613 is not lost due to external interference. This allows the first elastic element 613 to be gradually compressed tighter, resulting in a gradual increase in the elastic force on the breaking part 6121, thus improving the reliability of the anti-riot dismantling structure 610 under complex and violent dismantling conditions.

[0115] During forced dismantling, irregular vibrations may occur. The power storage component 630 can adapt to this complex vibration environment. Regardless of the direction or frequency of the vibration, the first elastic element 613 can continuously store power through the sliding of the sliding member 631 and the cooperation of the first pawl 632 and the first ratchet 633. This adaptability to complex vibration environments improves the stability of the entire oil well system when subjected to violent damage, ensuring the normal operation of the anti-forced dismantling function.

[0116] By controlling the energy storage of the first elastic element 613 through the energy storage component 630, the performance of the anti-blast demolition structure 610 is optimized, making it better adaptable to various situations. The energy storage component 630 works well in conjunction with other parts of the anti-blast demolition structure 610, such as the sealing plate 612 and the vibration fracture plate 614. Without changing the basic working principle of the original anti-blast demolition structure, it enhances its stability under normal use and ensures that the sealing plate 612 can be closed when subjected to violent damage, further improving the function of the anti-blast demolition structure 610 and enhancing the overall performance of the entire oil well system.

[0117] In some examples, an anti-opening component 640 is also included to prevent the sealing plate 612 from changing from a closed state to an open state. The anti-opening component 640 includes a second pawl 641, a second ratchet 642, and a fourth elastic member 643. The second pawl 641 is slidably disposed on the sealing plate 612, and the second ratchet 642 is disposed on the ring body 611. The second pawl 641 can be engaged with the second ratchet 642, so that the sealing plate 612 can only move in the direction of becoming closed. One end of the fourth elastic member 643 acts on the second pawl 641, and the other end acts on the sealing plate 612, providing the force for the second pawl 641 to engage with the second ratchet 642.

[0118] For example, the second pawl 641 is also made of high-strength alloy steel and is shaped like a right triangle. The hypotenuse is heat-treated to increase its hardness, thereby enhancing its engagement with the second ratchet 642. The second pawl 641 is slidably mounted on the sealing plate 612 via a groove. The length of the groove is slightly longer than the length of the right-angled side of the second pawl 641 to ensure that the second pawl 641 can slide flexibly within a certain range.

[0119] The second ratchet 642 is fixedly mounted on the ring 611, which surrounds the junction of the oil well pipe and the sealing plate 612, serving as a connection and positioning element. The second ratchet 642 is composed of multiple serrated segments, the angle and spacing of which match the bevel of the second pawl 641. The height of the serrations is moderate, ensuring that the second pawl 641 can be stably engaged without generating excessive resistance during the closing of the sealing plate 612.

[0120] The fourth elastic element 643 is a spring, which can provide sufficient clamping force without affecting the normal sliding of the second pawl 641 due to excessive elasticity. One end of the spring abuts against the second pawl 641 near the bottom, and the other end abuts against a specially reserved mounting hole on the sealing plate 612. In this way, the second pawl 641 is provided with a continuous force in the direction of the second ratchet 642.

[0121] The anti-opening component 640 is designed to prevent criminals from damaging the sealing plate 612 through violence or other means, thereby stealing crude oil. Utilizing the one-way locking characteristic of the second pawl 641 and the second ratchet 642, once the sealing plate 612 is in a closed state, it can only move in the direction of further closing and cannot be easily opened. This design, based on the one-way locking principle of a mechanical structure, requires no additional energy support, has high reliability and stability, and can function continuously.

[0122] During the movement of the sealing plate 612, the second pawl 641 is subjected to the elastic force of the fourth elastic element 643, and always remains in contact with the second ratchet 642. Due to the serrated structure of the second ratchet 642, when the second pawl 641 encounters the inclined edge of the serration, it will slide upward along the inclined edge under the action of the elastic force. After sliding past the top of the serration, it will quickly fall into the slot of the next serration under the action of the elastic force, thereby achieving the closing and locking of the sealing plate 612.

[0123] Once the sealing plate 612 is fully closed, if any criminal attempts to open it, the reverse movement of the sealing plate 612 will cause the second pawl 641 to engage tightly with the groove of the second pawl 642. Due to the special shape of the saw teeth, the second pawl 641 cannot easily disengage from the groove, thus preventing the sealing plate 612 from changing from a closed state to an open state, effectively protecting the crude oil in the oil well from being stolen.

[0124] The anti-theft component 640 significantly enhances the anti-theft capability of the oil well system. Even if criminals attempt to break the sealing plate 612, it will be difficult for them to breach the locking structure of the second pawl 641 and the second pawl 642, providing reliable physical protection for the oil well.

[0125] The anti-theft component 640 is based on a simple mechanical principle and does not rely on complex electronic equipment or external power sources. This reduces the risk of the anti-theft function failing due to electronic equipment failure or power interruption, and improves the stability and reliability of the entire oil well system.
