Among them, the sonde assembly 2 includes a mounting pipe 21, a measuring pipe 22 and a spare pipe 23. The mounting pipe 21 is arranged on the support body 1. One end of the mounting pipe 21 is connected to the power supply assembly 4, and the other end of the mounting pipe 21 is detachably connected to the measuring pipe 22. The measuring pipe 22 includes at least two pipe bodies 221 connected end to end, and two adjacent pipe bodies 221 are detachably connected. The spare pipe 23 can be detachably arranged between the mounting pipe 21 and the measuring pipe 22 to extend the length of the sonde assembly 2; the functional assembly 3 includes a lighting device 31, a distance sensor 32 and a camera device 33, and the functional assembly 3 is arranged at one end of the measuring pipe 22 away from the mounting pipe 21.

[0037] For the logging sonde proposed by the present utility model, the support body 1 provides a stable supporting effect for the entire logging sonde, facilitating the operator to place and construct; the mounting pipe 21 and the measuring pipe 22 are detachably connected for easy disassembly, installation and transportation. The mounting pipe 21 is connected to the power supply assembly 4 to realize the power supply process for the functional assembly 3; through the coordinated cooperation of the measuring pipe 22 and the spare pipe 23, during the actual measurement of the borehole, if it is found that the length of the measuring pipe 22 is insufficient, without replacing the measuring pipe 22, by installing the spare pipe 23 between the mounting pipe 21 and the measuring pipe 22, the extension effect of the sonde assembly 2 can be achieved, effectively solving the problem in the prior art that when the sonde length is insufficient, only the sonde can be replaced, resulting in low work efficiency, and improving the flexibility and adaptability of the logging sonde; in addition, the setting of the lighting device 31 in the functional assembly 3 can improve the unclear light in the borehole, enabling the operator to more clearly understand the internal environment of the borehole and providing better visual conditions for the measurement work.

By setting the functional assembly 3, the practicability and functionality of the logging sonde are improved.

[0038] The specific structure and functions of the logging sonde will be described below.

[0039] See Figure 2 , in the sonde assembly 2, the measuring pipe 22 is composed of at least two pipe bodies 221, and the multiple pipe bodies 221 are interconnected and coaxially arranged. Among them, regarding the number of the pipe bodies 221, for the convenience of description, two pipe bodies 221 are taken as an example below. In other embodiments, it can be three, four, etc., which are not limited herein.

[0040] Regarding the connection method of the two pipe bodies 221, in this embodiment, among two adjacent pipe bodies 221, an extension pipe 222 is fixedly connected to the end of one of the pipe bodies 221. Thread lines are provided on the outer periphery of the extension pipe 222, and the other pipe body 221 is threadedly connected to the extension pipe 222. By providing the extension pipe 222 and the threaded connection, it has good fastening performance, can withstand a certain amount of tensile force and torque, ensures the stability of the connection between adjacent pipe bodies 221, and reduces errors and faults caused by the loosening of the pipe bodies 221 during the measurement process. In other embodiments, the connection between two adjacent pipe bodies 221 can also be a snap connection, a pin connection, etc., which are not limited herein.

[0041] During the installation process, a seam is formed between the two pipe bodies 221 after the threaded connection. To improve the sealing performance inside the pipe body 221, a sealing pipe 223 is sleeved at the seam of two adjacent pipe bodies 221. The setting of the sealing pipe 223 can improve the sealing performance of the pipe body 221, effectively prevent impurities such as dust and liquid in the drilling hole from entering the inside of the pipe body 221, protect the internal measuring elements and circuits, and ensure the accuracy and reliability of the measurement.

[0042] See Figure 3 , one end of the measuring pipe 22 is connected to the installation pipe 21, and a functional component 3 is provided at the end of the measuring pipe 22 away from the installation pipe 21. To facilitate the installation of the functional component 3, a carrying pipe 25 is fixedly connected to the outer periphery of the pipe body 221 at the tail of the measuring pipe 22. A plurality of connecting pieces 26 are provided on the carrying pipe 25, and the connecting pieces 26 are arranged at intervals along the circumferential direction of the carrying pipe 25. The lighting device 31, the distance sensor 32, and the imaging device 33 are respectively arranged on the plurality of connecting pieces 26. Through the setting of the carrying pipe 25 and the connecting pieces 26, the lighting device 31, the distance sensor 32, and the imaging device 33 can have clear and fixed installation positions, avoiding the layout chaos and instability that may be caused by random installation on the measuring pipe 22, thereby improving the reliability and stability of the overall device. The plurality of connecting pieces 26 are arranged at intervals along the circumferential direction of the carrying pipe 25, which can ensure that the lighting device 31 realizes omnidirectional lighting without lighting dead angles, and the distance sensor 32 and the imaging device 33 can also obtain information from different angles, so as to more comprehensively and accurately reflect the situation inside the drilling hole.

[0043] It can be understood that the above-mentioned lighting device 31, distance sensor 32, and imaging device 33 are all selected from existing devices in the art, and their working principles and specific structures are not elaborated herein.

[0044] Specifically, four connecting pieces 26 are provided. The four connecting pieces 26 are arranged at intervals along the circumferential direction of the bearing pipe 25, and the included angle between two adjacent connecting pieces 26 is 90 degrees. Two lighting devices 31 are provided, and one lighting device 31 is provided on each of the two opposite connecting pieces 26, so as to improve the lighting effect of the functional component 3. Distance sensors 32 and imaging devices 33 are respectively provided on the remaining two connecting pieces 26.

[0045] Specifically, a protective plate 24 is provided at one end of the measuring pipe 22 away from the mounting pipe 21. The protective plate 24 can block rock debris, flowing mud, etc. that may fall in the drill hole, reducing the risk of damage to the functional component 3 and extending its service life. Secondly, the protective plate 24 can reduce the interference of external factors on the lighting device 31, the distance sensor 32 and the imaging device 33, thereby improving the reliability and accuracy of the measurement data. Moreover, the protective plate 24 provides certain structural reinforcement for the end of the measuring pipe 22, enhancing the impact resistance of the end of the measuring pipe 22 and making the entire logging sonde more durable in a complex drill hole environment.

[0046] Regarding the specific structure of the support body 1, refer to Figure 4 , in order to facilitate the cooperation between the mounting pipe 21 and the support body 1, a mounting hole 11 is formed through the support body 1. A limiting block 27 is provided at one end of the mounting pipe 21, and the other end of the mounting pipe 21 can pass through the mounting hole 11 and be clamped with the mounting hole 11. This structural design makes the connection between the mounting pipe 21 and the support body 1 simple and stable. The clamping method is quick to operate and can complete the installation of the mounting pipe 21 in a short time, improving the assembly efficiency. Secondly, the limiting block 27 provided at one end of the mounting pipe 21 can effectively prevent the mounting pipe 21 from being inserted into the mounting hole 11 excessively, ensuring the accuracy and consistency of the installation position, and thus guaranteeing the structural stability and reliability of the entire logging sonde.

[0047] Specifically, in order to facilitate the storage of the spare pipe 23, a spare hole 12 is provided on the support body 1, and the spare pipe 23 is detachably clamped in the spare hole 12. When the measuring pipe 22 needs to be lengthened, the spare pipe 23 is withdrawn from the spare hole 12 and installed between the two pipe bodies 221. When the measuring pipe 22 does not need to be lengthened, the spare pipe 23 can be clamped in the spare hole 12, which is convenient for quickly taking out and installing the spare pipe 23 when it is needed, improving the work efficiency.

[0048] It can be understood that, in order to ensure the smooth cooperation between the spare pipe 23 and the measuring pipe 22, a threaded groove is formed through the center of the spare pipe 23, so that one end of the spare pipe 23 can be threadedly connected to the mounting pipe 21, and an extension pipe 222 is also provided at the other end of the spare pipe 23, so that the spare pipe 23 can be threadedly connected to the pipe body 221 of the measuring pipe 22 through the extension pipe 222.

[0049] Moreover, in this embodiment, two spare pipes 23 are provided. The two spare pipes 23 can be threadedly connected to each other, so that one or two spare pipes 23 can be adaptively selected and installed between the installation pipe 21 and the measuring pipe 22 according to the required extended length of the measuring pipe 22, improving the flexibility and adaptability of the probe assembly 2.

[0050] It can be understood that the lengths of the two spare pipes 23 can be the same or different, and can be adjusted adaptively according to actual needs. In other embodiments, three, four or more spare pipes 23 can also be provided, which are not limited herein.

[0051] Furthermore, in order to improve the stability and strength of the logging probe, an anti-collision pad 14 is provided on the side wall of the support body 1, and / or a friction pad 15 is provided at the bottom of the support body 1. Providing the anti-collision pad 14 on the side wall of the support body 1 can effectively reduce or avoid the damage caused by the collision of the logging probe with other objects during use, transportation or storage, prolong the service life of the logging probe, and reduce the maintenance cost. Secondly, providing the friction pad 15 at the bottom of the support body 1 can increase the friction between the support body 1 and the contact surface, improve the stability of the logging probe when placed, and reduce the measurement error or accidental damage caused by sliding or displacement. Especially on an uneven surface, the friction pad 15 can better ensure the stable placement of the logging probe.

[0052] It can be understood that for the anti-collision pad 14 and the friction pad 15, one or more of materials such as rubber pads, silica gel pads, and frosted pads can be selected, which will not be elaborated herein.

[0053] To further improve the practicality and convenience of the functional component 3, a positioning groove 13 is opened at the top of the support body 1. A display screen 44 is provided in the positioning groove 13, and the display screen 44 is electrically connected to the functional component 3. The design of the positioning groove 13 provides a fixed and safe installation position for the display screen 44, reducing the risk of damage to the display screen 44 due to external collision or vibration, and ensuring the stable operation of the display screen 44. Integrating the display screen 44 on the support body 1 makes the operation of the entire logging probe more integrated and convenient. The operator can directly observe the display screen 44 while operating the logging probe without being distracted to check other devices, improving the safety and smoothness of the work.

[0054] See Figure 5, since the functional component 3 requires electricity to maintain its stable operation, one end of the installation pipe 21 is connected to the power supply component 4 to supply electricity to each device of the functional component 3. Regarding the power supply component 4, specifically, the power supply component 4 includes a connection line 41, a sealing block 42, a connector 43, and a power supply device. One end of the connection line 41 is connected to the sealing block 42, the other end of the connection line 41 is connected to the connector 43, the sealing block 42 is connected to one end of the installation pipe 21, and the connector 43 is connected to the power supply device. The setting of the sealing block 42 effectively prevents impurities such as dust and moisture from entering the interior through the connection between the connection line 41 and the installation pipe 21, protects the stability and safety of the power connection, avoids the occurrence of faults such as short circuits, and extends the service life of the power supply component 4. The connection line 41 plays a role in transmitting electricity. One end of it is connected to the sealing block 42, and the other end is connected to the connector 43. This connection method ensures the stable and reliable transmission of electricity, reduces power loss, and improves energy utilization efficiency. The connection between the connector 43 and the power supply device is simple and convenient, facilitating the quick replacement or connection of different power supply devices when needed, and increasing the flexibility and convenience of use.

[0055] It can be understood that existing devices such as storage batteries and generators can be selected as the power supply device, as long as they can provide electricity, and no further limitations are made here.
