Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of geological exploration, in particular to a geological exploration data acquisition device and method. BACKGROUND

[0002] Geological exploration plays an indispensable role in many fields by comprehensively using geological mapping, geophysical exploration, geochemical prospecting, drilling and other technical means to conduct in-depth investigation and research on geological elements such as rocks, soils and minerals of the earth. In the field of energy and resource development, geological exploration can accurately locate the buried position, reserve scale and distribution rule of oil, natural gas, coal, metal and non-metallic mineral resources, and provide scientific basis for mine exploitation and oil and gas field development, thereby ensuring national energy and resource security.

[0003] However, during drilling, some devices need to be taken out by the staff one by one for sampling, which wastes a lot of time. In addition, if the sampling structure is set inside the drill rod and used for a long time, it needs to be repaired, which is quite inconvenient to disassemble. SUMMARY

[0004] The present application aims to solve the problem of the lack of protective measures between the baffle and the shell in the prior art, and proposes a geological exploration data acquisition device and method.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A geological exploration data acquisition device and method, comprising a base, a stand column fixedly connected above the base, a threaded rod rotationally connected to the stand column, an adapter frame threadedly connected to the threaded rod, a drill rod rotationally connected to the adapter frame, a sampling mechanism arranged inside the drill rod, the sampling mechanism comprising a side cavity arranged inside the drill rod, the side cavity being used for placing a sampling box, the sampling box having a spring fixedly connected to one end thereof, a magnetic plate arranged at an opening of the sampling box, a rotating disc rotationally connected inside the sampling box, the rotating disc being eccentrically provided with a rotating block, an annular strip rotationally connected inside the sampling box, the annular strip having a fan-shaped gear fixedly connected to one end thereof away from the rotating block, the fan-shaped gear being meshingly connected with a rack rod, the rotating disc being transmissionally connected with a belt, the belt being transmissionally connected with a stand rod at one end thereof away from the rotating disc, the stand rod being fixedly connected with a first bevel gear above the stand rod, the first bevel gear being meshingly connected with a second bevel gear, the second bevel gear being fixedly connected with a wheel-side gear at one end thereof away from the first bevel gear, the wheel-side gear being meshingly connected with a rack plate.

[0006] The above-mentioned technical scheme further comprises: The sampling box is internally fixedly connected with a clasp ring, the clasp ring is slidably connected with a rack rod, and a hole for sampling is arranged on one side of the sampling box close to the rack plate.

[0007] The sampling box is internally fixedly connected with a third motor, the output end of the third motor is fixedly connected with a box gear, the box gear is meshingly connected with a clasp plate, and the clasp plate is slidably connected with the sampling box.

[0008] The first motor is fixedly connected to the upper portion of the stand, and the output end of the first motor is fixedly connected with a threaded rod.

[0009] The second motor is fixedly connected to the end of the adapter frame away from the threaded rod, the output end of the second motor is fixedly connected with a drill rod, and the drill rod is internally provided with a plurality of sampling mechanisms.

[0010] The connection structure of the adapter frame, the second motor and the drill rod enables the first motor to drive the adapter frame to move through the threaded rod, and simultaneously drive the second motor and the drill rod to accurately adjust the drilling position and depth. The second motor directly drives the drill rod to rotate, ensuring efficient transmission of drilling power and meeting the drilling needs of different hardness geological layers. The drill rod is internally provided with a plurality of sampling mechanisms, supporting continuous sampling of multiple layers and multiple points on the same drilling path, further improving the comprehensiveness and diversity of sample collection compared with a single sampling mechanism, reducing repeated drilling operations, and significantly improving exploration efficiency and data richness.

[0011] The control panel is fixedly connected to the upper portion of the base.

[0012] The control panel integrates the control functions of various components of the device, and the operator can conveniently control the operation of the first motor, the second motor, the third motor and the like through the control panel, to accurately control a series of operations such as drilling, sampling, component installation and disassembly. This centralized control method not only simplifies the operation process and reduces the operation complexity, but also reduces the frequent manual intervention of various components of the device, improves the accuracy and stability of the operation, and facilitates the operator to monitor the running state of the device in real time, adjust the exploration parameters in time, and ensure the safe and efficient exploration work.

[0013] The base is provided with a roller for movement.

[0014] The roller design at the bottom of the base endows the device with good mobility, enabling the geological exploration data acquisition device to easily transfer between different exploration sites and adapt to complex and diverse terrain environments, such as mountains, plains, grasslands, etc. Compared with traditional fixed or difficult-to-move exploration devices, this design greatly improves the flexibility and applicability of the device, reduces the consumption of manpower and material resources during device transportation, saves exploration preparation time, enables exploration personnel to quickly reach the target exploration area and carry out data collection work, and effectively improves the overall efficiency of exploration work.

[0015] The sampling box is slidably connected with the rack plate.

[0016] The sliding connection structure of the sampling box and the rack plate enables the rack plate to stably perform linear reciprocating motion under the drive of the turntable, thereby accurately controlling the opening and closing of the side sampling holes of the sampling box. During the sampling process, this structure ensures the continuity and sealing of the sampling operation. When the sampling tube is inserted into the soil for sampling, the rack plate can timely open the holes. After sampling is completed, the holes can be quickly closed, effectively preventing external soil and impurities from entering the inside of the sampling box, avoiding contamination of the sample, ensuring the purity of the collected sample and the accuracy of the data, and providing a reliable basis for subsequent geological analysis.

[0017] The present application has the following advantages: 1. In the present application, the built-in automatic sampling mechanism can realize multiple stratified sampling in a single drilling process. By controlling the forward and reverse rotation of the turntable, the sampling tube is accurately inserted and recovered, and the opening and closing mechanism is timely closed to avoid mixing of different layer soils. Compared with the traditional single sampling, drilling and collection mode, frequent drilling is not required, which significantly shortens the exploration time and improves the operation continuity and overall efficiency.

[0018] 2. The device adopts a quick-release structure of spring pre-tightening combined with a buckle plate, and the installation and disassembly of the sampling box can be quickly completed by driving the gear in the box through the third motor. When the sampling structure fails, the main drilling rod does not need to be disassembled, and a single person can quickly replace or repair the sampling box, effectively solving the complex disassembly problem of traditional devices, greatly reducing the equipment downtime, reducing maintenance cost and work intensity, and ensuring the smooth progress of exploration work.

[0030] In one embodiment, for the above-mentioned base 1, the base 1 is provided with a roller for movement at the bottom.

[0031] In the embodiment, the roller design at the bottom of the base 1 gives the device good mobility, so that the geological exploration data acquisition device can be easily transferred between different exploration sites to adapt to complex and diverse terrain environments such as mountains, plains and grasslands. Compared with traditional fixed or difficult to move exploration equipment, this design greatly improves the flexibility and applicability of the device, reduces the consumption of manpower and material resources during the transportation of the device, saves the preparation time for exploration, and enables the exploration personnel to quickly reach the target exploration area to carry out data acquisition work, effectively improving the overall efficiency of the exploration work.

[0032] In one embodiment, for the above-mentioned sampling box 10, the sampling box 10 is slidably connected with the rack plate 27.

[0033] In this embodiment, the sliding connection structure of the sampling box 10 and the rack plate 27 enables the rack plate 27 to stably perform linear reciprocating motion under the driving of the rotating disc 20, thereby accurately controlling the opening and closing of the side sampling holes of the sampling box 10, and ensuring the continuity and sealing of the sampling operation during the sampling process. When the sampling tube is inserted into the soil for sampling, the rack plate 27 can timely open the holes, and after the sampling is completed, the holes can be quickly closed, effectively preventing the external soil and impurities from entering the inside of the sampling box 10, avoiding the pollution of the sample, ensuring the purity of the collected sample and the accuracy of the data, and providing a reliable basis for subsequent geological analysis.

[0034] The working principle of the geological exploration data acquisition equipment in the present application is as follows: first, the base 1 is moved to a suitable position for geological exploration, and after reaching the specified position, the control panel 8 is controlled to perform exploration sampling. First, the first motor 3 is controlled to rotate, and then the second motor 6 is controlled to rotate. The output end of the second motor 6 drives the drill rod 7 to rotate to drill the soil, and the output end of the first motor 3 drives the threaded rod 4 to rotate. The threaded rod 4 rotates to drive the adapter frame 5 to move downward, thereby further driving the second motor 6 to move downward. Then, after drilling to a certain depth of the soil, the sampling mechanism is controlled. The sampling mechanism includes a rotating disc 20 arranged inside the sampling box 10. The rotating disc 20 is controlled to rotate to make the rotating block 21 reciprocate in the groove of the annular strip 19. One end of the annular strip 19 is fixedly connected to the inside of the sampling box 10, so the annular strip 19 reciprocates at the end close to the sector gear 18. The sector gear 18 is fixedly connected to the annular strip 19. The sector gear 18 is engaged with the rack rod 17 during the rotation of the rotating disc 20, so that the rack rod 17 slides in the clasp 16. One end of the rack rod 17 is provided with a sampling tube. When the rotating disc 20 continues to rotate, the sampling tube at one end of the rack rod 17 penetrates the sampling box 10 and the drill rod 7 to insert into the soil at the depth. During the reverse rotation of the rotating disc 20, the rotating block 21 slides in the annular strip 19 again, so that one end of the annular strip 19 swings again, and then the sector gear 18 is reversely engaged with the rack rod 17, so that the sampler at one end of the rack rod 17 is retracted into the inside of the sampling box 10. In addition, when the rotating disc 20 rotates forward, the belt 22 drives the vertical rod 23 to rotate, the vertical rod 23 rotates to drive the first bevel gear 24 and the second bevel gear 25 to engage, thereby driving the wheel side gear 26 to rotate to engage with the rack plate 27, thereby opening the hole of the sampler. When the rotating disc 20 reversely rotates, the belt 22 reversely drives the vertical rod 23 to rotate, the vertical rod 23 reversely drives the first bevel gear 24 and the second bevel gear 25 to engage, thereby reversely engaging the wheel side gear 26 with the rack plate 27 to block the hole on the side of the sampling box 10 to prevent the soil drilled by the drill rod 7 from entering the inside of the sampling box 10 to affect the accuracy of the subsequent data.

[0035] It is worth mentioning that when the sampling box 10 needs to be installed, the sampling box 10 is pushed by hand to extrude the spring 11, so that the spring 11 accumulates elastic potential energy, then the third motor 15 is controlled to rotate to drive the inner gear 14 to rotate to mesh with the buckle plate 13, further make the buckle plate 13 slide out from the inside of the sampling box 10 and insert into the inside of the drill rod 7, when it needs to be disassembled, the third motor 15 is controlled to rotate reversely to make the inner gear 14 rotate reversely, finally the buckle plate 13 completely enters into the inside of the drill rod 7, at this time the spring 11 releases the elastic potential energy to make the sampling box 10 pop out from the inside of the drill rod 7.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
