[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 1 As shown, a borehole multi-parameter information acquisition probe includes an external display controller 1 and a probe housing 3. Inside the probe housing 3, along the length of the probe housing 3, a rock temperature acquisition system 4, a water sample extraction system 6, and a fracture information acquisition system 7 are arranged sequentially.

[0035] The probe housing 3 houses a central control module 11. An external display controller 1 is connected to and controls the central control module 11 via an external cable 2. The central control module 11 is connected to and controls the rock temperature acquisition system 4, the water sample extraction system 6, and the fracture information acquisition system 7 via an internal cable 8. Information is transmitted through the external cable 2 and the internal cable 8. On the one hand, the required data can be obtained more timely and accurately. On the other hand, the depth of the probe can be determined by using the meter-level markings on the surface of the external cable 2.

[0036] The rock temperature acquisition system 4 includes several rock temperature sensors arranged in a ring. The probe housing 3 has a detection window 3.4 corresponding to the rock temperature sensor. The rock temperature sensor includes an infrared receiver 4.2, a rubber sleeve 4.1, a buzzer 4.4, a battery 4.3, and a main control board 4.5. The main control board 4.5 is fixed inside the probe housing 3. The infrared receiver 4.2, the battery 4.3, and the buzzer 4.4 are sequentially connected to the main control board 4.5. The rubber sleeve 4.1 surrounds the infrared receiver 4.2 and is connected to the side of the main control board 4.5, and is nested in the detection window 3.4.

[0037] The water sample extraction system 6 includes a water storage tank 6.1 and a motor 6.6 connected and fixed inside the probe housing 3. One end of the water storage tank 6.1 near the rock temperature acquisition system 4 is connected to a water guide pipe 6.8. The other end of the water guide pipe 6.8 passes through the rock temperature acquisition system 4 and is connected to a sampling tube 9. A sealing plate 10 is provided between the sampling tube 9 and the rock temperature acquisition system 4. A piston 6.2 is provided inside the water storage tank 6.1. The motor 6.6 controls the reciprocating movement of the piston 6.2 inside the water storage tank 6.1 through a drive mechanism. The sealing plate 10 can prevent water seepage into the rock temperature acquisition system 4. On the other hand, the sealing plate 10 and the end of the probe housing 3 cooperate to form a cavity 5.9, which facilitates water storage and is beneficial for water extraction by the sampling tube 9.

[0038] The crack information acquisition system 7 includes a main board 7.1 and several infrared camera devices. Several camera windows 3.1 for installing infrared camera devices are arranged around the probe housing 3. The main board 7.1 is installed on the end plate 3.2 of the probe housing 3 and is connected to control the infrared camera devices.

[0039] The probe housing 3 is also equipped with a guide wheel device 5, which facilitates the movement of the probe rod in the borehole and provides protection for the probe housing 3.

[0040] Furthermore, the guide wheel device 5 includes a partition plate 5.2, a limiting plate 5.1, and a guide wheel assembly. The partition plate 5.2 and the limiting plate 5.1 are connected to form an S-shaped structure, which, together with the probe housing 3, forms two cavities 5.9. The guide wheel assembly is connected and placed inside the cavity 5.9. The probe housing 3 is provided with a movable groove 3.3 corresponding to the guide wheel assembly.

[0041] Furthermore, to ensure that the guide wheel device 5 has a good buffering effect and can better adapt to drilling holes of different sizes, the guide wheel assembly includes a guide rail 5.8, a push rod 5.6, a rocker arm 5.5, a spring 5.3, a slider 5.7, and a guide wheel 5.4. The guide rail 5.8 is fixed on the partition plate 5.2, the slider 5.7 is slidably connected to the guide rail 5.8, the push rod 5.6 is rotatably connected to the slider 5.7, and the other end of the push rod 5.6 is rotatably connected to the middle of the rocker arm 5.5. One end of the rocker arm 5.5 is rotatably connected to the partition plate 5.2, and the other end is rotatably connected to the guide wheel 5.4 in the movable groove 3.3. One end of the spring 5.3 is connected to the slider 5.7, and the other end is fixed to the partition plate 5.2 away from the rocker arm 5.5.

[0042] When the probe moves inside the borehole, under normal conditions, spring 5.3 compresses slider 5.7, which in turn moves one end of push rod 5.6, increasing its inclination. Simultaneously, the other end of push rod 5.6 pulls rocker arm 5.5, which is connected to push rod 5.6, increasing its inclination. This causes guide wheel 5.4, connected to the end of rocker arm 5.5, to extend outward. When guide wheel 5.4 is compressed by the rock mass inside the borehole, it retracts inward, reducing the inclination of rocker arm 5.5 and pulling push rod 5.6 to reduce its inclination. Finally, push rod 5.6 compresses and pushes slider 5.7 to move on guide rail 5.8, compressing spring 5.3.

[0043] The presence of guide wheel 5.4 can effectively reduce the impact of rock mass on the probe rod and ensure the stability of the probe rod when it is lowered to the detection position.

[0044] Furthermore, the guide wheel device 5 is provided in two sets, respectively located between the rock temperature acquisition system 4 and the water sample extraction system 6, and between the water sample extraction system 6 and the fracture information acquisition system 7. The two sets of guide wheel devices 5 are preferably distributed on different vertical planes, so that all guide wheels 5.4 can contact more surfaces of the borehole wall and maintain the stability of the probe rod in the borehole.

[0045] To achieve reciprocating drive control of piston 6.2, preferably, the drive mechanism includes a drive rod 6.3 located at the end of piston 6.2 away from rock temperature acquisition system 4. The other end of drive rod 6.3 is connected to a sliding sleeve 6.7. A threaded rod 6.5 is threadedly fitted inside the sliding sleeve 6.7. The end of the threaded rod 6.5 is connected to the power output end of motor 6.6. The probe housing 3 is provided with several discs 6.4 that limit and support the threaded rod 6.5 and drive rod 6.3. The motor 6.6 provides driving force to rotate the threaded rod 6.5, thereby enabling the sliding sleeve 6.7 to reciprocate on the threaded rod 6.5, which in turn drives the drive rod 6.3 to drive piston 6.2 to reciprocate within water storage tank 6.1, forming a sampling action.

[0046] Furthermore, the infrared camera device includes an infrared camera 7.2, and a tempered glass 7.3 is embedded in the camera window 3.1 on the outside of the infrared camera 7.2.

[0047] Furthermore, the central control module 11 is fixed on the end plate 3.2. The end plate 3.2 is provided with a cable interface 12 for connecting the central control module 11. The end of the cable interface 12 located outside the end plate 3.2 is used to connect an external cable 2.

[0048] Furthermore, the external display controller 1 is equipped with a screen touch module 1.1, an instruction sending module 1.3, and a data receiving module 1.2. Instructions are issued using the screen touch module 1.1, the instruction sending module 1.3, and the data receiving module 1.2, and then sent to each system through the central control module 11 to complete the detection and acquisition function and obtain the required parameter data.

[0049] In practical use, the present invention is as follows: one end of the external cable 2 is connected to the cable interface 12, and the other end is connected to the external display controller 1. Then, the probe is inserted into the borehole. After the probe reaches the target position, the external display controller 1 sends a command to the central control module 11 through the external cable 2. The central control module 11 sends a command to the rock temperature acquisition system 4, the water sample extraction system 6, and the crack information acquisition system 7 through the internal cable 8. Each system starts to work to collect information, extract water, and feed back the acquired data to the central control module 11 through the internal cable 8. Then, the central control module 11 feeds back the data to the external display controller 1 through the external cable 2, thereby completing the data acquisition work in one go.
