Description

Technical Field

[0001] The utility model relates to the fields of mining engineering and safety communication, and particularly relates to a wellbore wireless bridge network transmission device. Background Art

[0002] Coal mine shaft survey is an important link in coal mine production, mainly used to obtain key information such as underground geological structure, resource reserves, gas content, and mine safety conditions. Through the survey, detailed data support can be provided for coal mine exploitation, ensuring the safety and efficiency of mining activities. With the increase in mine depth and the expansion of mining scale, it is particularly important to transmit underground data in real time and accurately. This can not only help managers promptly grasp the underground situation but also provide reliable emergency decision-making information in case of emergencies. Therefore, communication and data transmission equipment in the wellbore plays an important role in coal mine shaft survey. The existing wellbore wireless bridge network transmission system mainly consists of functional modules such as a mine flameproof and intrinsically safe camera, a mine flameproof and intrinsically safe uninterruptible power supply, a wireless bridge transmission device, lighting equipment, a car house hard disk storage and display device, etc. By installing a mine flameproof and intrinsically safe camera and an uninterruptible power supply on the vertical shaft cage, real-time acquisition of images of the vertical shaft wall can be achieved during the up and down movement of the cage, and the images are transmitted to the wireless bridge receiver on the wellhead tower through the transmitting end of the wireless bridge, and then transmitted to the monitoring room through the receiving end bridge, so as to realize functions such as acquisition, storage, and playback of images of the shaft wall, cable, and steel wire rope, thus achieving the purpose of replacing maintenance personnel to enter the well and perform maintenance with the cage, reducing the labor intensity of workers, and at the same time improving the efficiency and safety of maintenance.

[0003] The existing wireless bridge network transmission device establishes a stable communication link between the ground and the underground through radio frequency signals to achieve real-time transmission of underground data. The working principle of this device is to transmit monitoring data, images, audio signals, etc. underground to the ground monitoring center through a wireless bridge, without the need to lay a complex wired network, thus greatly reducing the installation cost and construction time. Among them, video acquisition relies on a mine flameproof and intrinsically safe camera, and the power supply is provided by a mine flameproof and intrinsically safe uninterruptible power supply. The camera uses a high-performance video acquisition and processing device, which can achieve high-definition acquisition and processing of video images within a certain moving speed. Finally, the video image transmission is realized through the transmitting end of the wireless bridge installed on the cage and the receiving end installed on the wellbore tower for wireless data transmission. After the image data is transmitted to the wireless bridge receiver on the wellbore tower, it is then connected to the ground industrial Ethernet through an Ethernet twisted pair, and finally transmitted to the monitoring room for real-time viewing and storage of images.

[0004] However, in existing wireless bridge network transmission devices, the equipped cameras are usually fixed at specific positions and cannot be flexibly adjusted in shooting angles after installation. Although this design of fixed cameras simplifies the installation process, due to the complex terrain and limited space in the mine, the monitoring field of view often cannot cover key areas, resulting in the emergence of monitoring blind spots and the inability to comprehensively monitor the underground operation conditions.

[0025] Refer to Figure 1 and Figure 4, a camera 17 is slidably connected inside a protective cover 6.

A rotary knob 21 is rotatably connected to the outer wall of the fixed ring 20. The rotary knob 21 can be rotated by the fixed ring 20 inside the protective cover 6. A limiting ring 22 is fixedly connected to the inside of the rotary knob 21. A sliding ring 23 is fixedly connected to the outer wall of the fixed ring 20.

[0026] Working principle: When the angle of the camera 17 needs to be adjusted, the cylinder 14 cooperates with the bushing 15 to push the connecting seat 16 to drive the protective sleeve 6 to rotate around the sliding shaft 3, so that the protective sleeve 6 can drive the camera 17 to rotate together, thereby adjusting the survey angle of the camera 17. At the same time, when the protective sleeve 6 rotates, it can drive the sliding sleeve 10 and the damping sleeve 8 to slide on the outer wall of the damping rod 7. Since the inside of the damping sleeve 8 is in a vacuum state and the limiting spring 9 is connected between the damping sleeve 8 and the damping rod 7, the damping sleeve 8 can slowly slide on the surface of the damping rod 7, thereby reducing the jitter of the camera 17 during adjustment, making the adjustment process smoother, so as to achieve the effect of adjusting the angle of the camera 17, ensuring the comprehensiveness of the survey. At the same time, the camera 17 can also be stabilized, improving the practicability of the device, expanding the scope of use of the device, and ensuring that the image data can be transmitted to the receiving end of the wireless bridge on the wellbore tower and then access the ground industrial Ethernet through the Ethernet twisted pair, and finally transmitted to the monitoring room for real-time viewing and storage of the images. When the camera 17 needs to be disassembled separately, by rotating the knob 21 and cooperating with the limiting ring 22 to drive the sliding rod 25 to slide in the groove inside the limiting ring 22, the sliding rod 25 can drive the clamping plate 24 to slide inside the sliding ring 23, and at the same time compress the return spring 26 until the clamping plate 24 completely slides out of the inside of the mounting ring 18, and then the camera 17 can be slid out of the protective sleeve 6. The return spring 26 can reset the clamping plate 24 afterwards, so as to achieve the effect of quickly disassembling the camera 17 separately, facilitating the maintenance of the camera 17, improving the convenience of the device, and extending the service life of the device.
