Description

Technical Field

[0001] The present invention relates to the technical field of geological surveying and mapping equipment, and particularly relates to an auxiliary device for environmental geological surveying and mapping. Background Art

[0002] In environmental geological surveying and mapping work, staff often need to carry out data collection, sample analysis, mapping and other work under complex and diverse terrain and environmental conditions. Traditional geological exploration and surveying auxiliary equipment has played an important role in long-term geological work. However, with the development of geological exploration work towards deeper, wider and more complex directions, and the continuous improvement of requirements for exploration accuracy, efficiency and environmental protection, some defects have gradually emerged, mainly reflected in the following aspects:

[0003] In terms of technical performance, the accuracy and resolution are limited. Many traditional devices are difficult to meet the high-precision requirements of modern geological exploration in terms of measurement accuracy and resolution. For example, the parameter acquisition is single. Traditional devices often can only acquire one type or a few types of geological parameters. For instance, conventional drilling equipment is mainly used to obtain core samples, focusing on understanding the lithology, stratification, etc. of rocks, and has limited ability to obtain other important parameters such as the geophysical properties and geochemical characteristics of rocks. This makes it difficult for geological workers to comprehensively and comprehensively analyze geological conditions and increases the difficulty of overall understanding of geological bodies.

[0004] Insufficient deep exploration ability: With the expansion of geological exploration to the deep part, traditional devices face many challenges in deep exploration. For example, the exploration depth and accuracy of deep strata are greatly reduced. Although drilling equipment can directly obtain deep cores, the drilling depth is limited, and the cost is high and the efficiency is low, making it difficult to meet the needs of large-scale deep geological exploration.

[0005] In terms of work efficiency, the data collection speed is slow. The data collection process of some traditional geological exploration equipment is relatively cumbersome and time-consuming. For example, some early field geological data collection equipment requires manual operation to record data, which is not only inefficient but also prone to human errors. In large-scale geological mapping work, relying on traditional manual observation and recording methods, it takes a lot of time and manpower to complete the investigation of a region.

[0006] Lag in data processing and analysis: Due to the single and backward functions of traditional devices, the data collected by them often requires a lot of manual processing and analysis in the later stage in the laboratory. This process is not only time-consuming and laborious, but also due to the limitations of data processing methods and tools, it may not be possible to extract valuable information from a large amount of data in a timely and effective manner. For example, for a large amount of data obtained from geological physical exploration, traditional manual drawing and simple data analysis methods are difficult to quickly and accurately identify abnormal features and geological laws, delaying the progress of the exploration work. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an environmental geological surveying and mapping auxiliary device to solve the problems in the prior art of environmental geological surveying and mapping, such as relatively single survey information, insufficient sampling data, and large workload of manual recording, which can significantly improve the overall level of environmental geological surveying and mapping work.

[0011] Furthermore, both ends of each arm section are coaxially provided with a positioning column and a socket. The positioning columns of the two connected arm sections are inserted into the sockets, and the cross section of the positioning columns is rectangular.

[0012] Furthermore, the bottom of the limiting boss also has the positioning column.

[0013] Furthermore, a number of cleaning rings are provided at the bottom end of the auxiliary support. Each cleaning ring is penetrated by a drill arm, and the inner wall of the cleaning ring has ejection holes for ejecting clear water or compressed air to clean the drill cuttings adhering to the drill arm.

[0014] Furthermore, the driving wheel is a circular toothed disc, and the driven wheel is a cylindrical gear. The cylindrical gear and the circular toothed disc are meshed and driven by a number of speed-changing gears. The speed-changing gears, the circular toothed disc and the cylindrical gear are all rotatably installed inside the auxiliary support.

[0015] Furthermore, both the driving wheel and the driven wheel are worm wheels, and the driving wheel is larger than the driven wheel. A number of worm shafts arranged in an annular array are meshed outside the driving wheel. The worm shafts are rotatably installed inside the auxiliary support. A first telescopic column is coaxially fixed to the end of the worm shaft, and a section of worm segment is coaxially fixed to the end of the first telescopic column. The driven gear is rotatably installed inside a bearing seat, and the bearing seat is fixed to the end of the second telescopic column.

Only one motor is required for sampling at multiple sample points, and the motor itself does not need to move down along with the drill pipe when driving the drill pipe to rotate like traditional exploration sampling equipment, which leads to great limitations and difficult operation in the installation height of the motor. Axial pressure can be applied by means of screw drive with trapezoidal threads. The hydraulic telescopic rod can be used to straighten the drill arm and maintain stability, and a low-pressure oil cylinder can be adopted, which is safer. In other words, the present invention greatly improves the work efficiency, realizes multi-point synchronous sampling, flexibly adjusts the size of the centralized sampling area, greatly shortens the cycle of the surveying and mapping work, and improves the work efficiency and sampling accuracy.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0035] The present invention provides a technical solution: an auxiliary device for environmental geological surveying and mapping, mainly including the following parts:

[0036] First, there is a multi-functional detection module, specifically including a high-precision positioning sub-module: adopting the combined technology of an advanced satellite positioning system (GNSS) and an inertial navigation system (INS), even in areas where satellite signals are blocked, accurate position information can be continuously provided through the inertial navigation system, ensuring a positioning accuracy at the centimeter level. At the same time, a high-precision barometer is equipped to measure the altitude in real time, further improving the accuracy of three-dimensional positioning. This detection module also has a ground-penetrating radar sub-module with a high-resolution ground-penetrating radar that can transmit and receive electromagnetic waves to detect geological structures and target objects at different depths underground. By analyzing the reflected waves, information such as stratigraphic layering, underground cavities, and rock distribution can be clearly identified, and the detection depth can reach dozens of meters. At the same time, a spectral analysis sub-module is also equipped, integrating a hyperspectral imager that can perform multi-band spectral scanning on ground targets; by analyzing the reflection characteristics of different substances in specific spectral bands, rock types, soil components, and vegetation coverage can be quickly and accurately identified, providing rich geochemical information for geological mapping.

[0037] Secondly, a sample collection module is provided, combined with Figure 1 As shown, its specific structure is as follows: It includes a drill arm 2. The drill arm 2 is made of high-strength lightweight materials as the sampling arm. Multiple sampling tools, such as core bits and soil samplers, are equipped at the end of the drill arm 2 and can be replaced according to different sampling requirements. In addition, an automatic depth following device of this module mainly includes a hydraulic telescopic rod 4 and a pressing plate 5 fixed to the telescopic end of the hydraulic telescopic rod 4. A limiting boss 6 is rotatably installed at the bottom of the pressing plate 5. The bottom of this limiting boss 6 is axially slidably inserted into the groove at the top of the drill arm 2. Moreover, under the action of the hydraulic telescopic rod, the limiting boss 6 can automatically move axially downward together with the drill arm 2. That is, the limiting boss 6 of this embodiment is driven by the hydraulic telescopic rod 4, so that this limiting boss 6 can follow the top of the drill arm 2 without separation. In order to maintain the stability of its vertical installation when replacing the drill arm 2 or extending the drill arm 2, and avoid the upper part from swinging during drilling. With such a design, the sampling depth can be automatically adjusted according to geological conditions to ensure accurate samples are collected at different depths. At the same time, a pressure sensor can also be set on the arm section between the drill arm 2 and the core drill 3 used as the drill bit, etc., to monitor the sampling resistance in real time during the sampling process and avoid damage to the sampling tool due to excessive force.

[0038] Thirdly, in this embodiment, a sample storage and identification system is also specifically provided. The collected samples are automatically placed into sample storage boxes with electronic tags. The electronic tags record detailed information such as the collection location, depth, and time of the samples, facilitating subsequent sample management and analysis.

[0039] In addition, in this embodiment, there is an auxiliary support 1 used as a carrier, such as Figure 1, the center of the auxiliary support 1 is used to install the drilling drive system, and a number of vertically arranged drill arms 2 are rotatably installed on the auxiliary support 1. All the drill arms 2 are annularly arrayed outside the drilling drive system to perform synchronous drilling on a given area at one time, and more comprehensively and accurately obtain geological exploration samples. Of course, if necessary, some of these drill arms 2 in this embodiment can be removed, which does not affect the sampling of the remaining drill arms 2.

[0040] In this embodiment, as Figure 1 , its drilling drive system includes a motor 8, a driving wheel 9, and a driven wheel 10 that surrounds and meshes with the driving wheel 9. The driven wheel 10 is rotatably installed on the auxiliary support 1, and the driving wheel 9 drives all the driven wheels 10 to rotate synchronously. Specifically, as Figure 1 , this drill arm 2 includes a number of arm segments 201 connected in series with each other. Each arm segment 201 is a lead screw that axially slides through the driven gear, that is, the drill arm 2 is composed of a number of lead screws connected in series, so as to achieve the effect of adjustable length. During drilling, it can be gradually added. When specifically manufactured, a lead screw with a trapezoidal thread can be preferably used. In addition, as Figure 1 , a transmission groove 20101 also needs to be opened on the surface of the lead screw along the length direction. This transmission groove 20101 is in sliding fit with a guiding key fixed to the inner wall of the shaft hole of the driven gear. That is, when the driven gear rotates self - rotatably, the guiding key drives the lead screw to rotate, and the threads on two mutually inserted arm segments 201 are connected to each other, that is, the threads can be smoothly connected and transitioned to form a continuously meshing thread pair. Based on the above structural design, a threaded seat sleeve 26 through which the arm segment 201 is thread - fitted must also be fixed on the support seat. The threaded seat sleeve 26 mainly combines the functions of the above - mentioned guiding key and the transmission groove 20101 to drive the drill arm 2 to move downward, so that the drill arm 2 axially drills to the corresponding depth for sampling.

[0041] In this embodiment, as Figure 1 shown, at both ends of each arm segment 201, there are a positioning post 7 and a receiving slot coaxially. The positioning post 7 of two adjacent arm segments 201 is inserted into the receiving slot, and the cross - section of the positioning post 7 is rectangular. When specifically manufactured, the positioning post 7 can also be provided at the bottom of the limiting boss 6 to control the stability of the top - most arm segment 201.

[0042] In order to clean the drill cuttings on the drill arm 2 when the drill arm 2 withdraws from drilling, as Figure 1 shown, a number of cleaning rings 12 are also provided at the bottom end of the auxiliary support 1. These cleaning rings 12 are all connected to a water pump or an air compressor. Each cleaning ring 12 is freely penetrated by a drill arm 2 correspondingly, and as Figure 8As shown, the inner wall of the cleaning ring 12 is provided with injection holes for injecting clean water or compressed air to clean the drill cuttings adhered to the drill arm 2. When necessary, a protective liquid such as lubricating oil or antirust oil can be added to the clean water.

[0043] In this embodiment, there are mainly two implementation methods for the transmission design of the driving gear and the driven gear:

[0044] The first design: As Figure 1 - Figure 2 shown, the driving wheel 9 is a circular tooth disc 9a, and the driven wheel 10 is a cylindrical gear 10a, that is, both are circular gear structures. In order to expand the dispersion area of the drill arm 2, or better change the speed, as Figure 2 shown, the cylindrical gear 10a and the circular tooth disc 9a are meshed and driven by a plurality of speed-changing gears 11, and the speed-changing gears 11, the circular tooth disc 9a, and the cylindrical gear 10a can be rotatably installed inside the auxiliary support 1.

[0045] The second design: Its purpose is to flexibly adjust the site distribution of sampling. Specifically, as Figure 3 shown, both the driving wheel 9 and the driven wheel 10 are worm wheels, and the driving wheel 9 is larger than the driven wheel 10, that is, the driving wheel 9 is the main worm wheel 9b and the driven wheel 10 is the secondary worm wheel 10b at this time. A plurality of worm shafts 15 arranged in an annular array are meshed on the outside of the main worm wheel 9b. The worm shafts 15 are rotatably installed inside or outside the auxiliary support 1. A first telescopic column 16 is coaxially fixed to the end of the worm shaft 15, and a section of worm segment 18 is coaxially fixed to the end of the first telescopic column 16. Referring also to Figure 7 , the secondary worm wheel 10b is rotatably installed in the bearing seat 19, and the bearing seat 19 is fixed to the end of the second telescopic column 17. The second telescopic column 17 is fixedly installed on the auxiliary support 1. It is also necessary to keep the second telescopic column 17 in each pair of telescopic columns parallel to the first telescopic column 16, and the two telescopic columns move synchronously in a telescopic manner. In this way, the worm segment 18 installed on the first telescopic column 16 and the secondary worm wheel 10b installed on the second telescopic column 17 can always be kept meshed, and can be adjusted to any position to flexibly adjust the size of the sampling area and the interval between sampling points.

[0046] In this embodiment, as Figure 4As shown, each of the two telescopic columns includes an outer sleeve 20 and an inner inserted column 21. A number of annularly-arrayed guiding grooves 24 are provided on the inner wall of the outer sleeve 20, and a number of guiding sliders 22 are fixed on the side wall of the inner inserted column 21. The guiding sliders 22 and the guiding grooves 24 are in one-to-one sliding fit. A strip-shaped threaded hole 25 is provided on the pipe wall of the outer sleeve 20. After the locking bolt 23 passes through the strip-shaped threaded hole 25, it is fastened in the guiding slider 22 and the inner inserted column 21, thereby locking and fixing them. In use, when adjusting the size of the sampling area, the inner inserted columns 21 of each can be pulled out by the same length. Scale lines can be drawn on the inner inserted columns 21. Or in practice, due to the meshing effect of the worm and worm gear, the pulled-out lengths of the inner inserted columns 21 of the two telescopic columns will also adaptively remain consistent to a certain extent.

[0047] Specifically in the installation, as Figure 7 shown, the outer sleeve 20 of the second telescopic column 17 of this embodiment is of an L-shaped structure. One end is arranged perpendicular to the end face of the auxiliary support 1, and the other end is fixed with a bearing seat 19. Specifically, a pair of bearing seats 19 can be provided to install two bearings. To adapt to the movement design of the diamond drill arm 2, as Figure 6 shown, there is a strip-shaped through hole 101 penetrating the upper and lower end faces on the auxiliary support 1. The strip-shaped through hole 101 allows the bearing seat 19 and the driven gear to move, so that when the drill arm 2 can flexibly change its position, it can still be rotatably installed. Finally, to facilitate the load-bearing capacity and stability of the entire device during installation and drilling, as Figure 1 shown, at the bottom edge of the auxiliary support 1, there is a blind pin foot 13 protruding downward respectively. The hydraulic cylinder of the hydraulic telescopic rod 4 is installed inside the blind pin foot 13, and an adjustment base 14 is fixed at the bottom end of the blind pin foot 13 to support the auxiliary support 1 and firmly install this device. This surveying and mapping auxiliary device adopts the above-mentioned drill arm 2 drive structure, and can perform synchronous sampling with only one high-power motor 8 for sampling, avoiding the deficiency that multiple motors 8 are required for multiple sampling points when the traditional motor 8 is directly connected to the drill arm 2 for drilling. Moreover, in order to keep the drill arm 2 drilling, it is not necessary to vertically move the motor 8 together as in the existing equipment, and thus it is extremely convenient for the installation and wiring of the motor 8.

[0048] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side", "the other side", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0049] In addition, terms such as "identical" do not require the components to be absolutely identical, but rather there can be minor differences. The term "vertical" merely means that the positional relationship between components is more vertical relative to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
