Description

Technical Field

[0001] This invention belongs to the field of oilfield well workover technology, and specifically relates to a visual operation information wireless transmission device, system and operation method. Background Technology

[0002] In the tense atmosphere of well workover operations, the derrick operators on the second-level platform play a crucial role, especially during the core process of tripping in and out of the drill string. Their every action directly impacts the safety and efficiency of the operation. Derrick operators need to possess a high degree of focus and coordination to cope with complex and ever-changing working environments.

[0003] During tripping operations, derrick operators typically need to perform multiple tasks simultaneously. One of these tasks is to steadily hold the heavy tubing with one hand, ensuring it doesn't sway or fall off during descent. This requires extremely high levels of strength control and balance skills. Meanwhile, the other hand grips a signal bar, using a series of pre-set hand gestures or light signals to communicate in real-time with the driller below, indicating critical information such as the drilling speed and stopping position.

[0004] However, in actual operations, the roar of machinery, the spraying of drilling fluid, and the chatter of surrounding workers create a chaotic working environment. In this environment, even if the derrick operator waves the signal baton with all their might and gives clear hand gestures, it is sometimes difficult to ensure that the signal is accurately transmitted to the driller. Especially during emergency or complex operations, ambiguous or delayed signals can easily lead to misunderstandings by the driller, resulting in operational errors such as sudden acceleration, deceleration, or inaccurate stopping of the drilling tools. This can not only damage equipment but also cause personal injury, posing a serious safety hazard.

[0005] In addition, frequent communication breakdowns and misunderstandings can directly affect the overall progress of the work, leading to slower work speed and increased costs and time consumption. Summary of the Invention

[0006] The purpose of this invention is to provide a visual operation information wireless transmission device, system and operation method to solve the problems of unclear signal transmission, misleading the driller, and potential safety hazards and slow operation speed caused by the noise of the work site during the tripping operation of the second-level platform derrickman in well workover operations.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A visual operation information wireless transmission device includes a display, an extension component, a reset component, a fixing component, a magnifying glass, and a signal receiving module. Mounting plates are fixedly mounted on the top and bottom of the display. The reset component and the extension component are mounted on the mounting plates, and a fixing component is positioned between the reset component and the extension component to limit the extension component's movement. The magnifying glass is located at the end of the extension component. The signal receiving module is located inside the display and is used to receive command signals for display on the display.

[0008] Furthermore, the extension assembly includes an extension groove and an extension rod, with the extension rod slidably disposed inside the extension groove, and a magnifying glass fixedly connected to one end of the extension rod.

[0009] Furthermore, there are four extension slots, all of which are located on the surface of the display. The four extension slots are set on the surface of the mounting plate, and a mounting bracket is fixedly installed on the surface of the magnifying glass. One end of each of the four extension rods is fixedly connected to one side of the mounting bracket.

[0010] Furthermore, the reset assembly includes a reset groove, a reset spring, and a reset handle. The reset spring is disposed inside the reset groove, and the reset handle is slidably disposed inside the reset groove, with the reset handle located inside the reset spring.

[0011] Furthermore, the fixing component includes fixing holes and fixing pins, with the fixing pins connecting to the reset handle, and several fixing holes evenly arranged on the extension rod.

[0012] Furthermore, a rotating assembly is provided on one side of the display. The rotating assembly includes a servo motor, a rotating block, and a rotating rod. The output end of the servo motor is connected to the rotating rod via a coupling, and a rotating block is provided on the rotating rod. The rotating rod is a threaded rod, and the rotating block is a threaded block adapted to the rotating rod. When the servo motor starts, the rotating rod rotates, causing the rotating block to move on the rotating rod. A sliding assembly is provided on the other side of the display. The sliding assembly includes a sliding rod and a sliding block, and a sliding block is slidably connected to the sliding rod.

[0013] Furthermore, a cleaning plate is provided between the bottom of the rotating block and the top of the sliding block, and the rotating block drives the cleaning plate to move; a telescopic rod is fixedly connected to one side of both the rotating block and the sliding block, which is used to drive the cleaning plate connected to the telescopic rod to extend to one side when the magnifying glass moves to one side. The bottom of one telescopic rod and the top of the other telescopic rod are fixedly connected to the top and bottom of two other cleaning plates, respectively. The other two cleaning plates are located on both sides of the magnifying glass and are used to scrape off the dust attached to the surface of the magnifying glass.

[0014] Furthermore, a cleaning cotton is fixedly connected to one side of the cleaning plate. The cleaning cotton is used to adhere to the surface of the magnifying glass and the display area of ​​the monitor.

[0015] Secondly, the present invention provides a visual operation information wireless transmission system, including a visual operation information wireless transmission device and a remote controller. The remote controller is provided with a remote control module and a signal transmission module for sending instructions to the visual operation information wireless transmission device and displaying them on a display screen.

[0016] Thirdly, the present invention provides an operation method for a visual operation information wireless transmission device, comprising: Commands are sent via remote control to display on the monitor and issue warnings. Pulling the reset handle moves the fixing pin inside the fixing hole while squeezing the reset spring inside the reset groove, causing the fixing pin to separate from the fixing hole. Move the magnifying glass to one side, which in turn moves the extension rod to one side inside the extension groove. After the magnifying glass moves to the predetermined position, release the reset handle. The reset spring pushes the fixing pin inside the reset groove into the fixing hole to limit the extension rod, thereby adjusting the position of the magnifying glass and magnifying the key parts on the display.

[0017] Compared with the prior art, the present invention has the following technical effects: This invention creatively integrates wireless remote control and signal transmission technologies to construct a highly efficient and precise wireless transmission system for visual operation information. The system aims to ensure that every instruction issued by the derrick operator is accurately transmitted to the driller through stable wireless signal transmission, thereby avoiding signal mistransmission or omission caused by factors such as on-site noise and obstructed vision, and greatly improving communication efficiency and safety at the work site.

[0018] The core of this invention lies in its comprehensive and detailed instruction system. The remote control module is meticulously designed with a variety of operational instructions, including lifting, lowering, stopping, checking for normal operation, and warning of danger. These instructions cover the key aspects of well workover operations, ensuring the driller can clearly grasp the progress of the operation and potential risks. When the derrickman inputs instructions through the remote control module, the signal transmitting module quickly transmits the instructions wirelessly, and the signal receiving module accurately captures these instructions and instantly transmits them to the display module for intuitive presentation. This process not only achieves rapid instruction transmission but also ensures the accuracy and completeness of the instructions, allowing the driller to clearly understand the next operational requirements.

[0019] To further enhance the system's practicality and convenience, this invention also incorporates innovative designs such as an extension component, a reset component, and a fixing component. The extension component allows users to adjust the display's viewing angle and magnification according to actual needs, ensuring the driller can clearly see instructions even from a distance. This is especially important for small text, which becomes even clearer with the magnification of the magnifying glass. The reset component provides a quick way to restore the display to its initial state, facilitating rapid cleanup of the work area after instructions have been transmitted. The fixing component ensures the display's stability during operation, effectively preventing displacement or detachment due to accidental collisions or vibrations, further guaranteeing the system's reliability and safety.

[0020] Furthermore, this invention fully considers the cleaning and maintenance of the equipment. A cleaning plate is added to the rotating assembly, and it is equipped with soft and highly absorbent cleaning cotton. This design allows users to easily clean the surfaces of the magnifying glass and display without affecting normal operation, effectively removing dust and dirt, ensuring the clarity of the display and the long service life of the equipment.

[0021] In summary, the visual operation information wireless transmission system provided by this invention, with its high efficiency, safety, and reliability, builds a solid bridge for communication between derrickmen and drillers on the second-level platform during well workover operations. It not only solves many problems existing in traditional communication methods but also improves the overall system performance and user experience through a series of innovative designs. Therefore, this invention has significant practical application value and broad prospects for promotion, and is expected to play an important role in future well workover operations.

[0049] The output of the remote control module is connected to the input of the signal transmitting module, the output of the signal transmitting module is connected to the input of the signal receiving module, and the output of the signal receiving module is connected to the input of the display module.

[0050] Thus, after the command is transmitted via the remote control module, the signal transmitting module transmits the signal, which is then received by the signal receiving module and finally displayed by the display module.

[0051] This technical solution proposes a visual operation information wireless transmission system, which integrates a visual operation information wireless transmission device and a remote control, and realizes the rapid and accurate transmission and display of instructions through wireless transmission. The system employs wireless transmission, enabling command transfer between the remote control and the visual operation information wireless transmission device without the need for a physical connection, greatly improving operational convenience and flexibility.

Furthermore, due to its wireless transmission method, the system boasts strong scalability, allowing for the addition of more commands or functions to meet specific needs.

[0056] By interacting with the display via the remote control, operators can more intuitively understand the current operating status and command requirements, enhancing the interactivity and controllability of the operation. This interactivity helps improve the operator's attention and focus, reducing the occurrence of operational errors.

[0057] In summary, the proposed visual operation information wireless transmission system offers several advantages, including convenient wireless transmission, diverse and clear instructions, real-time display and alarm functions, improved work efficiency, ease of maintenance and expansion, and enhanced operator interactivity. These benefits are significant for improving operational safety, reliability, and efficiency.

[0058] In Example 4, during use, the reset handle 43 is pulled to one side, thereby causing the fixing pin 52 to move to one side inside the fixing hole 51. At the same time, the fixing pin 52 moves to one side inside the reset groove 41 and squeezes the reset spring 42. After the fixing pin 52 separates from the fixing hole 51.

[0059] Move the magnifying glass 9 to one side, thereby causing the extension rod 32 to move to one side inside the extension groove 31. When the magnifying glass 9 is moved to the appropriate position, release the reset handle 43.
