Description

Technical Field

[0001] This utility model belongs to the field of underwater borehole detection, specifically relating to a borehole image detection cabin for use in a water-covered environment. Background Technology

[0002] In geological exploration, the detection of the internal structure of boreholes is crucial. However, many boreholes face complex environments with high humidity and large amounts of water accumulation, posing numerous challenges to detection equipment. Traditional detection equipment is insufficient in terms of waterproofing, easily leading to short circuits or corrosion due to water intrusion, resulting in equipment damage and data loss. Simultaneously, existing equipment is susceptible to water flow disturbances during underwater operations, resulting in poor image quality, low data transmission efficiency, and an inability to accurately reflect the true situation inside the borehole. Furthermore, underwater data transmission and power supply face significant difficulties. As geological exploration advances into deeper and more complex water-covered borehole scenarios, the shortcomings of traditional equipment in terms of waterproofing, disturbance resistance, functional integration, and data transmission stability become increasingly apparent, failing to meet the demands for high precision, high efficiency, and high reliability. Therefore, developing a borehole detection device for water-covered environments with long-lasting reliable waterproof sealing, stable internal support, and efficient data transmission has become a key direction for addressing current industry pain points and promoting the upgrading of geological exploration technology.

[0016] The following will refer to the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0017] like Figures 1-3 A borehole image detection cabin for use in a water-covered environment includes a transparent shell 10, an upper base 9, a lower base 17, a traction main cable 11, a camera 16, an electric guide rail 13, and a lifting device.

[0018] The top of the transparent housing 10 is sealed to the upper base 9, and its bottom is sealed to the lower base 17. The electric guide rail 13 is vertically arranged inside the transparent housing 10, and the camera 16 is mounted on the slider of the electric guide rail 13. The camera 16 is connected to the camera connecting cable 12, and the electric guide rail 13 is connected to the guide rail connecting cable. The camera connecting cable 12 and the guide rail connecting cable are respectively connected to the traction main cable 11 through the splitter 20. The traction main cable 11 passes through the top of the upper base 9 and is connected to the lifting device.

[0019] Specifically, the borehole image detection chamber of this invention is designed to penetrate deep into a water-bearing borehole and capture image information of the borehole wall 1 inside the borehole using a camera 16, thereby achieving high-definition visual detection of borehole wall defects. The electric guide rail 13 drives the camera 16 to move up and down within the transparent housing 10, allowing for fine-tuning of the camera 16's height to capture images of the borehole wall 1 at different locations. The lifting device controls the raising and lowering of the detection chamber via a traction main cable 11, which also functions as the traction main cable for the entire detection chamber. Multiple cables are twisted together inside the main cable for power supply and communication. The borehole wall 1 images captured by the camera 16 are transmitted to an external receiving device via the camera connecting cable 12, the splitter 20, and the traction main cable 11. The movement of the electric guide rail 13 receives external control signals through the guide rail connecting cable, the splitter 20, and the traction main cable 11.

[0020] It should be noted that the splitter 20 involved in this utility model is existing technology, capable of twisting multiple cables into one, such as the camera connection cable 12 and the guide rail connection cable. Both cables pass through the splitter 20 and are fixed, twisted within the traction main cable 11, and then combined into a complete cable through the outer cable sleeve of the traction main cable 11. The outer cable sleeve of the traction main cable 11 can be made of steel wire rubber cable sleeve, possessing high strength and high sealing characteristics, suitable for traction and underwater operations.

[0021] The transparent outer shell 10 of this invention features a sealed structure that effectively adapts to submerged environments, protecting the normal operation of internal electronic components. The electric guide rail 13 moves the camera 16 up and down, expanding the longitudinal range of image acquisition. Multiple cables are combined into a main traction cable 11 via a splitter 20, simplifying the wiring structure. Simultaneously, the main traction cable 11 serves multiple functions, including power supply, signal transmission, and traction, enhancing the device's integration and reliability. The design of outputting images and data to the ground via cable avoids interference from the underwater environment.

[0022] Alternatively, a power supply can be configured inside the probe cabin to power various electronic components, or the power lines of each electronic component can be led out through the main traction cable 11.

[0023] Furthermore, the bottom of the upper base 9 and the top of the lower base 17 are both inserted into the transparent outer shell 10. A first sealing layer 22 is provided between the bottom of the upper base 9 and the transparent outer shell 10, and a second sealing layer 18 is provided between the top of the lower base 17 and the transparent outer shell 10.

[0024] The first and second sealing layers are existing technologies, such as rubber gaskets or O-rings. The upper base 9 and the lower base 17 can be connected to the transparent outer shell 10 by bolts.

[0025] Furthermore, it also includes a hollow main shaft 14, the top and bottom of which are rotatably connected to an upper base 9 and a lower base 17, respectively; cameras 16 are provided on both sides of the main shaft 14; a cavity is provided inside the lower base 17, and a motor 21 is installed in the cavity. The output end of the motor 21 is connected to the main shaft 14 to drive the main shaft 14 to rotate; the motor connection cable 15 of the motor 21 passes through the main shaft 14 and is connected to the splitter 20. The splitter 20 twists the motor connection cable 15, the camera connection cable 12, and the guide rail connection cable into the traction main cable 11.

[0026] The motor 21 can be connected to the main shaft 14 via a gear set to achieve the rotation of the main shaft 14. During detection, the motor 21 starts and drives the main shaft 14 to rotate around its own axis. The main shaft 14 drives the cameras 16 on both sides to rotate synchronously. During the rotation, the cameras 16 collect circumferential images of the hole wall. The start, stop and speed of the motor 21 receive external control signals through the motor connection cable 15, the splitter 20 and the traction main cable 11.

[0027] In addition, the cameras 16 are wide-angle cameras, preferably two of which are symmetrically distributed on both sides of the main shaft 14. The rotation angle of the main shaft 14 is less than 180°, for example, in the range of 0°-90°, and the motor 21 rotates reciprocally without continuous rotation to avoid tangling of the camera connecting cables 12. The wide-angle view of the two cameras 16 is used to completely capture the hole wall 1. This design can avoid tangling of the two camera connecting cables 12. The camera connecting cables 12 are preferably spiral elastic cables with a certain tensile capacity, which can be appropriately lengthened or shortened as the cameras 16 move up and down and the main shaft 14 rotates.

[0028] Furthermore, the lifting device includes a frame 1, a traction motor 2, a pulley mechanism 3, and a rotating drum 4;

[0029] The rotating drum 4 is rotatably mounted on the frame 1. The traction motor 2 is connected to the rotating drum 4 through the pulley mechanism 3 to drive the rotating drum 4 to rotate. The traction main cable 11 is wound around the rotating drum 4 multiple times. One end of the traction main cable 11 is fixedly connected to the upper base 9, and the other end of the traction main cable 11 is connected to the control device 5.

[0030] The pulley mechanism 3 is existing technology, including pulleys and a belt, which enables the rotation of the rotating drum 4. The rotating drum 4 converts its rotational motion into the linear motion of the traction main cable 11 by winding or releasing the cable, thereby achieving the raising and lowering of the probe cabin. The control device 5 transmits control signals and image signals to various electronic components via the traction main cable 11. The control device 5 is existing technology, such as a computer or control box, used to receive image information and send control signals. The power supply configured inside the probe cabin can be connected to an external power supply via the traction main cable 11. The external power supply is installed inside the rotating drum 4 to provide power. Alternatively, a battery can be directly configured inside the probe cabin to power the various electronic components, in which case the traction main cable 11 only transmits signals and data, not electricity.

[0031] The connection between the control device 5 and the traction main cable 11 is preferably a wireless connection. The end of the traction main cable 11 can be connected to a corresponding wireless module, such as a wireless transceiver, to realize wireless communication with the control device 5. The wireless module is fixedly installed on the rotating drum 4.

[0032] Furthermore, the top of the upper base 9 is fixedly connected to the bearing seat 7, the top of the bearing seat 7 is fixedly connected to the cable retainer 6, and the main traction cable 11 passes through and is fixedly connected to the cable retainer 6.

[0033] The cable retainer 6 enhances the connection strength between the main traction cable 11 and the detection cabin, effectively preventing the main traction cable 11 from loosening or falling off during traction. The cable retainer 6 serves a load-bearing function and is based on existing technology, such as cable clips, clamps, flange rings, and clamping devices.

[0034] Furthermore, a counterweight 19 is fixedly connected to the bottom of the lower base 17; multiple spring telescopic rods 8 are respectively provided on the side of the bearing seat 7 and the side of the counterweight 19, and the ends of the spring telescopic rods 8 are rotatably connected to rollers, which are used to contact the hole wall.

[0035] The spring-loaded telescopic rod 8 is existing technology and includes a sleeve, a telescopic rod, and a built-in spring. The elastic force of the built-in spring provides an outward thrust to the telescopic rod, causing the roller to fit tightly against the borehole wall 1, forming radial support for the probe cabin. The gravity of the counterweight 19 lowers the center of gravity of the probe cabin.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
