Description

Technical Field

[0001] The present invention relates to the technical field of geophysical detection, in particular to a geological drilling physical detection device. Background Art

[0002] Geological borehole physical detection equipment is a type of equipment specifically designed to obtain subsurface geological information. It uses various physical methods and techniques to detect and analyze the properties of underground rock formations. A resistivity logging tool is a geophysical exploration device that assesses formation characteristics by measuring the resistivity of rocks and ores in a borehole. Its core principle is to supply power to the rock formation and measure the potential difference, calculating the apparent resistivity and subsequently analyzing parameters such as geological structure, porosity, and permeability.

[0003] Existing resistivity logging tools typically consist of electrodes, a probe, a winch, and a main unit. During logging, the electrodes are inserted into the ground, the probe is lowered into the well using a winch, and a cable connects the electrodes and probe to the main unit. The probe records the resistivity data of the rock formation, which is then processed and transmitted to the main unit for analysis. The main unit calculates the resistivity based on the data collected by the probe and the known rock formation properties, and generates a related geological profile. This data allows geological engineers to conduct in-depth analysis of the underground rock structure, porosity, permeability, and other physical properties, further understanding groundwater levels, mineral distribution, and oil and gas reservoirs.

[0004] For example, in the prior art, the patent with authorization announcement number CN212479202U discloses a resistivity logging instrument, comprising a base, a cavity formed therein, a bracket fixedly connected to the inner upper wall of the base, a motor fixedly connected to the side wall of the bracket, a drive wheel fixedly connected to the output shaft of the motor, a support block fixedly connected to the upper surface of the base, a first transmission wheel rotatably connected to the side wall of the support block, a support plate fixedly connected to the side wall of the base, a second transmission wheel rotatably connected to the side wall of the support plate, a wiring harness jointly connected to the drive wheel, the first transmission wheel, and the second transmission wheel, and four roller racks fixedly connected to the lower surface of the base, two roller racks jointly fixedly connected to a load-bearing shaft. The above-mentioned device prevents the wiring harness from being exposed and affecting the appearance by providing a cavity, reduces safety hazards, and prevents the resistivity logging instrument from slipping during operation and affecting the test results by providing a piston rod.

[0005] However, the above-mentioned resistivity logging tool still has certain defects when used:

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figures 1 to 7A geological drilling physical detection device includes a resistivity logging instrument host 1 and a box cover 2, a control panel 3 and a display screen 4 connected to the resistivity logging instrument host 1. A rainproof film 5 is fixedly connected to one side of the box cover 2. Two symmetrically arranged fixed plates 7 are fixedly connected to the bottom end of the rainproof film 5. A plurality of connecting magnetic blocks 8 are fixedly connected to each fixed plate 7. A plurality of fixed magnetic blocks 9 corresponding to the positions of the connecting magnetic blocks 8 are fixedly connected to the surface of the resistivity logging instrument host 1. A rain curtain 6 is fixedly connected to the bottom of the rainproof film 5. A back film 11 is fixedly connected between the inner bottom of the rainproof film 5. A wire groove 12 is provided on the surface of the back film 11. An observation plate 13 is fixedly connected to the middle of the rainproof film 5. The ends of the two fixed plates 7 are fixedly connected to clamping blocks 10, and the positions of the two clamping blocks 10 correspond.

[0039] The geological drilling physical detection device of the present invention can pull the fixing plate 7 to pull out the rainproof film 5 from the inside of the box cover 2 when it rains, and use the clamping block 10 to splice the two fixing plates 7 together, and then adsorb the connecting magnetic block 8 on the fixing plate 7 and the fixing magnetic block 9 to fix the fixing plate 7. At this time, the rainproof film 5 is stretched into an inclined state, and the rain curtain 6 and the back film 11 are also unfolded. The user passes the cable through the cable groove 12 to connect with other equipment; the multi-layer flexible protective cover formed by the rainproof film 5, the rain curtain 6 and the back film 11 can fully cover the cable interface and surface gaps of the resistivity logging instrument host 1 to prevent rainwater from seeping through the joints, ensuring that the equipment can still work normally under adverse weather conditions; The adsorption design of the connecting magnetic block 8 and the fixing magnetic block 9 not only ensures the stability of the rainproof film 5, but also facilitates disassembly and reuse. Even in scenarios of frequent use, it can maintain a good fixing effect and extend the service life of the equipment; an iron plate or a magnetic plate is embedded in the box cover 2, so that when the rainproof film 5 is not needed, the rainproof film 5 and other components can be fixed by adsorbing the fixing plate 7 to prevent them from being scattered outside, ensuring the overall neatness and portability of the equipment; the snap-in block 10 can connect the two fixing plates 7 together to form a more stable fixing structure, which helps to maintain the stability of the rainproof film 5 and effectively prevent the rainproof film 5 from collapsing in the middle or warping at the edges during use, ensuring that it always remains flat and stable.

[0040] As a preferred technical solution of the present invention, a power supply module 15 and a temperature sensor 16 are fixedly connected to one side of the box cover 2, and a heating coil 14 is fixedly connected to the inner side of the rainproof film 5. The power supply module 15, the temperature sensor 16 and the heating coil 14 are electrically connected.

[0041] Specifically, the heating coil 14 is installed on the inner side of the rainproof film 5, and the heating function can be activated when necessary to prevent water vapor from condensing inside the rainproof film 5 and on the observation plate 13, so that the user can always maintain a clear field of vision, which is crucial for real-time monitoring of data changes and quick decision-making. Preventing water vapor condensation can also reduce the risk of corrosion and other damage to the equipment due to moisture intrusion, thereby extending the overall service life of the equipment; the temperature sensor 16 is used to monitor the temperature changes inside and outside the equipment in real time. When it is detected that the temperature difference may cause water vapor condensation, the system can automatically start the heating coil 14 for heating to prevent water vapor condensation from occurring.

[0042] As a preferred technical solution of the present invention, the outer wall of the rainproof film 5 is fixedly connected to a connecting block 17, which is located above the observation plate 13. A winding groove 18 is provided in the connecting block 17, and a rotating shaft 19 is rotatably connected in the winding groove 18. A cleaning cloth 20 is sleeved on the outer wall of the rotating shaft 19, and one end of the cleaning cloth 20 passes through the connecting block 17 and is fixedly connected to a positioning rod 21. A fixed groove 23 is provided at one end of the connecting block 17, and one end of the rotating shaft 19 passes through the fixed groove 23 and is fixedly connected to a coil spring 24, and the other end of the coil spring 24 is fixedly connected to the inner wall of the fixed groove 23.

[0043] Specifically, before using the observation plate 13, the user can pull out the cleaning cloth 20 to wipe the surface of the observation plate 13, thereby ensuring the clarity and visibility of the observation plate 13, so that the user can observe the detection data; when the user pulls the positioning rod 21 to pull out the cleaning cloth 20, the rotating shaft 19 will rotate and stretch the coil spring 24. After releasing the positioning rod 21, the elastic force of the coil spring 24 will cause the rotating shaft 19 to rotate in the opposite direction, thereby automatically retracting the cleaning cloth 20 into the winding slot 18. Through the action of the coil spring 24, the cleaning cloth 20 can be automatically rolled back into the winding slot 18 after use, without the need for manual operation, which simplifies the user's operating steps and improves the convenience of use.

[0044] As a preferred technical solution of the present invention, a mounting groove 25 corresponding to the position of the control panel 3 is opened in the main unit 1 of the resistivity logging instrument, and a rotating rod 26 is fixedly connected to the middle of both sides of the control panel 3. The rotating rod 26 is rotatably connected to the inner wall of the mounting groove 25. An operating groove 27 corresponding to the position of the control panel 3 is opened on the front side of the main unit 1 of the resistivity logging instrument, and a baffle 28 is rotatably connected to the top of the operating groove 27, and a limiting component is connected to the bottom of the operating groove 27.

[0045] Specifically, when using the resistivity logging instrument host 1, when parameters need to be adjusted, the user presses the front side of the control panel 3 and rotates the control panel 3 around the rotating rod 26. Then the user opens the baffle 28 and fixes the control panel 3. The user can then put his hand into the operating slot 27 and press the button to adjust the parameters, which makes it convenient for the user to adjust the parameters. The user can use the control panel 3 without removing the rainproof film 5, thereby maintaining the overall waterproof performance of the equipment, effectively preventing rain or other moisture from entering the interior of the equipment, and reducing the risk of failure caused by moisture; at the same time, the tilt of the control panel 3 will drive the display screen 4 thereon to tilt, so that the display screen 4 and the observation panel 13 remain parallel, ensuring that the user can obtain the best viewing angle, facilitating viewing and analysis of data, and improving the user experience.

[0046] As a preferred technical solution of the present invention, the limiting assembly includes an insert rod 30 and a push rod 32. Two movable grooves 29 are provided in the operating groove 27. The two movable grooves 29 are slidably connected with the insert rod 30. A push rod 32 is fixedly connected between the two insert rods 30. A sliding groove 31 corresponding to the position of the push rod 32 is provided on the bottom surface of the operating groove 27, and two slots 33 corresponding to the position of the insert rod 30 are provided at the bottom of the control panel 3.

[0047] Specifically, after the control panel 3 is rotated, the user pushes the push rod 32 to drive the two insertion rods 30 to be inserted into the slots 33, thereby fixing the control panel 3 and preventing the control panel 3 from rotating or shaking when the user operates the control panel 3, thereby enhancing the stability of the control panel 3 and reducing the risk of misoperation.

[0048] As a preferred technical solution of the present invention, a sliding groove 34 is provided on one side of the surface of the resistivity logging instrument main unit 1, and a connecting plate 35 is slidably connected in the sliding groove 34.

The outer wall of the moving rod 36 is in contact with the bottom surface of the control plate 3. A pressure spring 40 is fixedly connected to the upper part of the connecting plate 35. The bottom end of the pressure spring 40 is fixedly connected to the surface of the resistivity logging instrument main unit 1. A positioning block 38 is fixedly connected to the top of the connecting plate 35, and a positioning groove 39 corresponding to the position of the positioning block 38 is provided on the surface of one of the fixed plates 7.

[0049] Specifically, during the rotation of the control panel 3, the bottom of the control panel 3 will squeeze the moving rod 36, driving the moving rod 36 to move downward, and then pulling the connecting plate 35 and the positioning block 38 downward, so that the positioning block 38 is inserted into the positioning groove 39, thereby providing further fixation for the fixed plate 7; when the control panel 3 is reset, the pressure spring 40 will push the connecting plate 35 to rise, thereby canceling the fixation of the fixed plate 7; through this arrangement, it is ensured that the fixed plate 7 will not accidentally loosen or shift during use, further enhancing the stability of the rainproof film 5 during use. The linkage design between the moving rod 36 and the connecting plate 35 allows the entire process to be completed automatically without the need for additional manual operation. The user only needs to rotate the control panel 3 to automatically lock the position of the fixed plate 7.

[0051] Specifically, after the control panel 3 has completed its rotation, the drive assembly will push the movable plate 43 and the display screen 4 to slide along the slide bar 42, causing the display screen 4 to slide out from the surface of the control panel 3 and approach the observation panel 13, thereby further facilitating the user to observe the readings on the display screen 4 and improving the accuracy and efficiency of data reading.

[0052] As a preferred technical solution of the present invention, the driving assembly includes a connecting rod 45, a secondary piston 46, a connecting pipe 47, a liquid storage pipe 48, a main piston 49, a pressure rod 50, a return spring 51 and a liquid guide pipe 52.

[0053] Specifically, when the control panel 3 is pressed down, the bottom of the control panel 3 will squeeze the pressure rod 50, and the pressure rod 50 will push the main piston 49 downward, thereby pressing the hydraulic oil in the reservoir tube 48 from the guide tube 52 into the connecting tube 47, and the hydraulic oil will then push the secondary piston 46 to move, and the secondary piston 46 will push the connecting plate 35 and the display screen 4 to move through the connecting rod 45, so that the display screen 4 pops up, which is convenient for the user to observe; when the control panel 3 is reset, under the pressure of the reset spring 51, the main piston 49 rises, and the hydraulic oil is re-sucked into the reservoir tube 48 through the guide tube 52, and the hydraulic oil in the connecting tube 47 is sucked back into the reservoir tube 48, and the secondary piston 46 then descends, driving the connecting rod 45 and the movable plate 43 back to their original position, thereby resetting the display screen 4; the hydraulic drive system ensures that the sliding process of the display screen 4 is smooth and impact-free, avoiding wear and noise problems of the mechanical structure.

[0054] As a preferred technical solution of the present invention, a pull ring 22 is fixedly connected to the middle of the positioning rod 21.

[0055] Specifically, the pull ring 22 is fixed at the middle of the positioning rod 21, providing a more convenient gripping point for the user.
