Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The existing control devices for vehicle-mounted wellhead devices are all placed in explosion-proof boxes to protect the devices inside. However, in the existing vehicle-mounted explosion-proof boxes, the control position occupied by the control devices inside the explosion-proof boxes is large, so the size of the explosion-proof boxes used is large. In actual applications, it is more troublesome to operate, and the control devices inside the boxes are all electronic control devices with poor shock resistance.

A dual power conversion switch 5, a DC voltage regulator 4 and a wireless communication board 3 are installed on the first plate 2. At the same time, the box cover 1 has good sealing performance, and the connection between the box cover 1 and the box body 7 has good air tightness, which can ensure the safety of the electronic equipment inside the box body 7 in the oil well environment.

[0035] Box body 7: Box body 7 is the main structure of the entire control box and is made of explosion-proof material. It can withstand certain external impacts and pressures and protect internal electronic equipment from damage. A second plate 10 is installed inside the box body 7, and communication equipment, PLC controller 6, algorithm controller 9 and signal terminals 12 are installed on the second plate 10.

[0036] Dual power conversion switch 5: used to automatically or manually switch between the main power supply and the backup power supply to ensure that when either power supply fails, the other power supply can still provide continuous power, thereby improving the reliability and stability of the system.

[0037] DC voltage stabilizer 4: Converts input AC power or unstable DC power into stable DC output, provides a stable power supply environment for the electronic equipment in the control box, and prevents voltage fluctuations from causing damage to the equipment.

[0038] Communication equipment 8: including wired or wireless communication modules, used to realize communication between the control box and the remote monitoring center or other related equipment, transmit real-time data and instructions, and facilitate remote monitoring and management.

[0039] PLC controller 6: responsible for receiving sensor input signals, executing preset control logic, and outputting control signals to the actuator.

[0040] Wireless communication board 3: Provides additional wireless communication capabilities, supports wireless protocols such as Wi-Fi, Bluetooth, Zigbee, etc., enhances the communication flexibility and coverage of the control box, and facilitates data transmission and remote control in complex environments.

[0041] Signal terminal 12: used to connect external sensors, actuators and other equipment, introduce external signals into the control box for processing, or output control signals to external equipment to achieve signal transmission and execution of control instructions.

[0042] Algorithm controller 9: used to perform data processing, pattern recognition, predictive control, etc., to improve the intelligence level of the control system, optimize the control strategy, and improve control accuracy and efficiency.

[0043] Shock-absorbing component 14: The shock-absorbing component 14 is installed outside the box 7 to reduce the impact of vibration of the vehicle-mounted wellhead device on the electronic equipment in the control box during movement, ensure that the equipment can still operate stably under complex road conditions, and protect the safety of the electronic equipment inside the control box.

[0044] Among them, two shock-absorbing components 14 are respectively installed at the upper and lower ends of the outside of the box body 7, and the shock-absorbing components 14 include a vibration isolator 17, a first connecting plate 16, a second connecting plate 18 and a connecting bolt member 15. The first connecting plate 16 is installed on the outside of the box body 7. The upper end of the vibration isolator 17 is connected to the first connecting plate 16 through the connecting bolt member 15, and the lower end of the vibration isolator 17 is connected to the second connecting plate 18 through the connecting bolt member 15. The second connecting plate 18 is used to connect to the vehicle-mounted wellhead device. The vibration can be effectively reduced by the shock absorber, and the connection method of the first connecting plate 16 and the box body 7 is an integrated molding setting, which means that the connection method of the first connecting plate 16 and the box body 7 is a non-detachable connection, such as welding or an integrated casting molding setting, which is not specifically limited here.

[0045] In actual application, the main power supply supplies power to the entire control box through the dual power supply conversion switch 5. When the main power supply fails, it automatically switches to the backup power supply to ensure uninterrupted power supply. The DC voltage regulator 4 converts the input power into stable DC power to provide stable working voltage for each electronic device. The external sensor transmits the collected signal to the control box through the signal terminal 12. The PLC controller 6 and the algorithm controller 9 receive these signals, execute the corresponding control logic and algorithm calculation, and generate control instructions. The PLC controller 6 outputs the control instructions to the external actuators, such as pumps, valves, etc., through the signal terminal 12 to realize the automatic control of the wellhead device. The communication device 8 and the wireless communication board 3 are responsible for transmitting real-time data and control status to the remote monitoring center, and receiving instructions from the monitoring center to realize remote monitoring and management.

[0046] Furthermore, the box body 7 is made of explosion-proof material, and different components are integrated on the box cover 1 and the box body 7 through plates, and are placed in a superimposed manner, that is, one part is placed on the box cover 1 and the other part is placed inside the box body 7, so that all components can be avoided from being installed inside the box body 7, which can effectively save space inside the box body 7. The shock-absorbing component 14 effectively reduces the impact of vibration on the equipment during vehicle driving, and improves the stability and reliability of the control box.

[0047] Optionally, a accommodating space is provided on the box cover 1, and the first plate 2 is installed in the accommodating space through a supporting rail; the DC voltage regulator 4, the dual power conversion switch 5 and the wireless communication board 3 are all arranged on the first plate 2, the DC voltage regulator 4 is arranged on one side of the dual power conversion switch 5, and the wireless communication board 3 is installed above the DC voltage regulator 4.

[0048] In the embodiment of the present application, a storage space is provided on the box cover 1, and the storage space provides a safe and stable installation environment for the first plate 2 and the equipment thereon.

And the storage space is sealed by the box cover 1 to prevent the erosion of the internal equipment by external environmental factors, such as dust, moisture, corrosive gas, etc.

[0049] Among them, the first plate 2 is installed in the accommodating space of the box cover 1 through the supporting rail. This installation method not only ensures the stability of the first plate 2, but also facilitates disassembly and maintenance when necessary. The DC regulator 4, dual power conversion switch 5 and wireless communication board 3 are integrated on the first plate 2.

[0050] Through the above layout design, the first plate 2 and the components thereon are all installed in the accommodation space of the box cover 1. This design not only ensures the stability and safety of each component, but also facilitates subsequent maintenance and upgrading. When a component fails or needs to be updated, the component can be removed and replaced separately without large-scale disassembly and reinstallation of the entire control box, which not only saves maintenance time and cost, but also improves the efficiency of maintenance work.

[0051] Optionally, a housing is provided on the box body 7, the second plate 10 is installed in the housing through a support rail, and a power supply and a connection cable are placed between the lower end of the second plate 10 and the housing. The signal terminal 12 is provided below the communication device, the algorithm controller 9 is provided on one side of the communication device, and the PLC controller 6 is provided at the upper end of the communication device.

[0052] In an embodiment of the present application, an accommodating portion is provided inside the box body 7 for installing the second panel 10 and the equipment thereon. The accommodating portion usually has precise size and shape to ensure that the second panel 10 can be securely installed therein and provides sufficient space for power supply, connecting cables, etc.

[0053] The second board 10 is installed in the receiving portion of the box 7 through the support rail, thereby ensuring the stability of the second board 10 and facilitating subsequent maintenance and upgrading. In addition, the communication equipment, PLC controller 6, algorithm controller 9 and signal terminal 12 are all installed on the second board 10.

When a component needs to be repaired or replaced, the component can be removed and replaced separately without large-scale disassembly and reinstallation of the entire control box. This design greatly saves maintenance time and cost and improves the efficiency of maintenance work.

[0056] Therefore, by integrating different components on the box cover 1 and the box body 7 through plates, and adopting a stacking method, it is avoided that all components are installed inside the box body 7, which can effectively save the space inside the box body 7. In addition, by providing a shock-absorbing component 14, when the explosion-proof box body 7 vibrates, the vibration of the control equipment inside the explosion-proof box body 7 can be reduced or avoided, thereby effectively protecting the electronic control equipment inside the explosion-proof box body 7.
