Description
Technical Field
[0001] This application relates to the field of electrical resistivity tomography, and in particular to a novel multifunctional electrical resistivity tomography instrument for deep mineral exploration. Background Technology
[0002] Electrical resistivity tomography (E tomography) instruments, also known as geophysical electrical resistivity spectrometers, are essential tools in the field of geophysical exploration. They play a crucial role in numerous areas, including geological surveys, resource exploration, and engineering surveys. With prolonged mining, shallow mineral resources are gradually depleting. To ensure a continuous supply of mineral resources, mining development has begun to extend to deeper levels. In this context, the new multi-functional electrical resistivity tomography instrument for deep exploration has come into play. Its powerful deep-penetration capabilities allow it to detect depths of several thousand meters. By comprehensively applying various electrical resistivity principles, it can accurately identify potential deep ore bodies, helping exploration personnel achieve breakthroughs in deep mineral exploration. For example, in some large mines with a long history of mining, this instrument has successfully discovered hidden metallic ore bodies deep within, providing new resource reserves for the sustainable development of the mines.
[0003] A search revealed Chinese Patent Publication No. CN217820903U, which discloses a novel multifunctional electrical resistivity tomography (OT tomography) instrument for deep mineral exploration. The instrument includes an OTI body. A cover plate is rotatably connected to one side of the OTI body via a first rotating shaft. A display screen is fixedly embedded in the inner wall of the cover plate. Rotating plates are fixedly mounted on both sides of the OTI body adjacent to the cover plate. Each rotating plate has a second rotating shaft, through which a height adjustment plate is rotatably connected. The bottom of each height adjustment plate has a hollow adjustment column, within which an adjustment rod slides. Universal wheels are located at the four corners of the bottom of the OTI body. The height adjustment plate is concave, with two adjustment columns on each side, each integrally formed with the height adjustment plate on that side. Multiple adjustment buttons are spaced apart on the upper surface of the OTI body, and a keyboard is located adjacent to these buttons. This invention is highly practical.
[0004] The aforementioned patent mentions the following beneficial effects: "By adjusting the support rod to support the main body of the electrical resistivity meter, it is easy to isolate the main body when there is water on the floor, making operation simple, convenient, quick, and time-saving; in narrow areas, the main body of the electrical resistivity meter can be directly placed on the floor and dragged by the casters, avoiding the drawback of the traditional method of directly sliding and rubbing the main body of the electrical resistivity meter on the ground, which can easily cause damage to the main body." Although the above solution avoids the drawback of the traditional method of directly sliding and rubbing the main body of the electrical resistivity meter on the ground, in the existing technology, electrical resistivity meters are often used in field scenarios such as geological exploration and engineering testing. The working environment generally contains particulate matter such as sand, rock fragments, and pollen, which easily adhere to the screen surface. The screens of some electrical resistivity meters are difficult to clean. Dust particles adhere to the screen surface or in the gaps, which can block pixels, resulting in blurry display content and uneven brightness, affecting the accuracy of the data read by the operator (such as measurement values, waveform curves, etc.). Therefore, a new type of multifunctional electrical resistivity meter for deep mining exploration is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a novel multifunctional electrical resistivity tomography instrument for deep mineral exploration, which aims to improve the problem of dust accumulation on the screen of some existing electrical resistivity tomography instruments, where dust particles adhere to the screen surface or crevices.

[0013] Through the above technical solution, the miniature fan generates suction as a power source. The connecting pipe connects the dust collection box to the input end of the miniature fan. After the dust collection box collects dust, it is sucked into the miniature fan through the connecting pipe and then transported through the dust outlet pipe, forming a continuous channel from dust collection to transmission, thus maintaining a clean environment inside the electrochemical analyzer.
[0014] Preferably, a collection box is detachably connected to the outside of the dust outlet pipe, and two positioning bolts are threadedly connected to both the front and rear sides of the collection box. A filter screen is fixedly connected to the left side of the collection box.
[0015] Through the above technical solution, the dust discharge pipe is connected to the collection box, which facilitates the discharge and storage of dust; the positioning bolts fix the collection box, which is convenient for disassembly and cleaning; the filter screen prevents dust from escaping, ensures the collection effect, avoids secondary pollution, and protects components such as the fan, ensuring that the collection mechanism works continuously and effectively, so that the dust is properly treated.
[0016] Preferably, the cover plate has square openings on both the left and right sides inside, and telescopic dustproof plates are fixedly connected to the upper and lower sides inside the square openings. The adjacent sides of the two telescopic dustproof plates are fixedly connected to the upper and lower sides of the sliding guide frame.
[0017] Through the above technical solution, the square opening on the cover provides a movement track for the sliding guide frame. The telescopic dustproof plates on the upper and lower sides inside are connected to the sliding guide frame and extend and retract synchronously when the frame slides. This not only does not affect its normal movement, but also effectively prevents dust from entering the inside of the electrophysiology instrument. While achieving screen dust removal, it also ensures the cleanliness of the inside of the equipment and improves the dustproof capability of the equipment.
[0018] Preferably, the outer side of the sliding guide frame is slidably connected to the inner wall of the square opening, and the rear side of the soft brush is in contact with the front side of the screen;
[0019] Through the above technical solution, the sliding guide frame slides on the inner wall of the square opening, driving the soft brush to closely adhere to the screen surface, thereby achieving a comprehensive cleaning of the screen; at the same time, the frame is slidably connected inside the cover plate to ensure stable movement, enabling the soft brush to accurately and smoothly remove screen dust, maintain clear screen display, and provide good data display conditions for exploration work.
[0020] Preferably, the motor is externally fixedly connected to the inside of the cover plate, and the rear side of the dust collection box is fixedly connected to the outside of the sliding guide frame;
[0021] With the above technical solution, the motor is fixed inside the cover plate, saving space and facilitating power transmission; the dust collection box is fixed outside the sliding guide frame, and collects dust in real time as the frame moves, so that dust removal and dust collection are carried out simultaneously. The components are tightly connected, reducing the risk of dust falling and contaminating the environment, improving the overall cleaning efficiency, and ensuring the stable operation of the electrochemical analyzer.
[0022] Preferably, the external sliding guide frame is slidably connected to the inside of the cover plate, and the external positioning bolt is detachably connected to the inside of the electrical resistivity meter body;
[0023] Through the above technical solution, the sliding guide frame slides stably inside the cover plate, ensuring the normal operation of the dust removal function; the positioning bolts can detachably connect the collection box and the main body of the electrical resistivity meter, which not only ensures that the collection box is fixed and stable, but also facilitates disassembly and cleaning. This allows the equipment to have efficient dust removal and dust collection functions, while also facilitating later maintenance and extending the service life of the equipment.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. In this utility model, the rotating plate is driven by a motor to rotate, which drives the fixed rod to move in the inner cavity of the sliding guide frame, so that the sliding guide frame slides up and down in the square opening. The soft brush on the inner wall of its front side continuously wipes the screen surface, which realizes the dust removal of the screen of the electrical resistivity meter. This ensures that the operator can accurately capture data changes and reduce engineering hazards or resource misjudgments caused by blurry display.
[0026] 2. In this utility model, the miniature fan draws air out of the dust collection box through the connecting pipe to create negative pressure. The dust collection box sucks in the dust wiped by the soft brush. The air and dust enter the collection box through the dust outlet pipe after passing through the miniature fan. The filter screen blocks the dust, and the purified air is discharged. This achieves the collection of dust and avoids secondary pollution, thereby directly reducing the probability of dust adhering to the screen, buttons, heat dissipation holes and other parts, and reducing the risk of equipment failure.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.
[0033] Example: A novel multifunctional electrical resistivity tomography instrument for deep mineral exploration, with reference to... Figure 1 It includes an electrical resistivity meter body 1, a fixing block 2 installed on the rear side of the electrical resistivity meter body 1, a dust removal mechanism 3 installed inside the fixing block 2, and a collection mechanism 4 installed on the top of the electrical resistivity meter body 1.
[0034] Reference Figures 1 to 3The dust removal mechanism 3 includes a motor 31, which converts electrical energy into mechanical energy to drive the rotating plate 32 to rotate, thereby driving the entire dust removal assembly to work and realize the automatic dust removal function of the electrical resistivity meter screen 15, reducing the frequency of manual cleaning and improving work efficiency. The motor 31 is externally fixedly connected to the inside of the fixed block 2. The driving end of the motor 31 is fixedly connected to the rotating plate 32. The front side of the rotating plate 32 is fixedly connected to the fixed rod 33. One end of the fixed rod 33 is connected to the rotating plate 32, and the other end is set in the sliding guide frame 34, which plays the role of connection and transmission. The circular motion of the rotating plate 32 is converted into the linear reciprocating motion of the sliding guide frame 34, ensuring that the soft brush 36 can effectively cover the surface of the screen 15 for dust removal. The sliding guide frame 34 is provided on the outside of the fixed rod 33. The sliding guide frame 34 provides a mounting carrier for the soft brush 36 and slides stably in a straight line along the square opening 37 under the drive of the fixed rod 33, ensuring that the soft brush 36 can accurately and smoothly clean the dust on the surface of the screen 15. The sliding guide frame 34 has an inner cavity 35. Multiple soft brushes 36 are fixedly connected to the front inner wall of the sliding guide frame 34. Through their soft bristles, they can gently and effectively remove dust and stains from the surface of the screen 15, avoiding dust from affecting the display effect of the screen 15 and ensuring that the operator can accurately read the data of the electrical instrument.
[0035] Specifically, in the dust removal mechanism 3, the motor 31 converts electrical energy into mechanical energy to drive the rotating plate 32. The fixed rod 33 converts the circular motion into the linear reciprocating motion of the sliding guide frame 34. The sliding guide frame 34 drives the soft brush 36 to slide smoothly on the surface of the screen 15, using the soft bristles to gently remove dust and dirt. At the same time, the inner cavity 35 of the sliding guide frame 34 ensures smooth movement of the components, realizing automatic and efficient dust removal of the screen 15 of the electrical resistivity meter, reducing the amount of manual cleaning work, ensuring the screen 15 is clear, and enabling operators to read data in real time and accurately, providing good equipment display conditions for the smooth development of deep mining exploration work.
[0036] The outer side of the sliding guide frame 34 is slidably connected to the inner wall of the square opening 37. The rear side of the soft brush 36 is in contact with the front side of the screen 15. The inner left and right sides of the cover plate 14 are provided with square openings 37. The upper and lower sides of the inner side of the square opening 37 are fixedly connected with telescopic dustproof plates 38. The telescopic dustproof plates 38 can extend and retract during the sliding of the sliding guide frame 34, which can prevent dust from entering the inside of the electrophysiology instrument without hindering the normal movement of the sliding guide frame 34, thus playing a good dustproof and sealing role. The adjacent sides of the two telescopic dustproof plates 38 are fixedly connected to the upper and lower sides of the sliding guide frame 34. The outer side of the motor 31 is fixedly connected to the inside of the cover plate 14, and the outer side of the sliding guide frame 34 is slidably connected to the inside of the cover plate 14.
[0037] Specifically, the sliding guide frame 34 slides along the inner wall of the square opening 37, driving the soft brush 36 to clean dust from the surface of the screen 15, ensuring that the screen 15 clearly displays data. The square opening 37 on the cover plate 14 provides a movement track for the sliding guide frame 34. At the same time, the telescopic dustproof plate 38 inside is connected to the upper and lower sides of the sliding guide frame 34 and extends and retracts synchronously during the sliding process. This not only does not hinder the normal movement of the sliding guide frame 34, but also effectively prevents dust from entering the interior of the electrical resistivity meter. Together with the motor 31 driving the entire dust removal assembly, it realizes the dual functions of automatic dust removal of the screen 15 of the electrical resistivity meter and dust prevention inside the equipment, ensuring the stable operation of the electrical resistivity meter and accurate data reading.
[0038] Reference Figure 1 The top of the electrical resistivity meter body 1 is fixedly connected to a keyboard 11. Through the keyboard 11, the operator can input various commands and set parameters to realize the function control and operation of the electrical resistivity meter, and conveniently and quickly complete the acquisition and processing of exploration data. The electrical resistivity meter body 1 is equipped with multiple adjustment buttons 12. The adjustment buttons 12 are used to finely adjust the various functions and parameters of the electrical resistivity meter. Operators can adjust parameters such as measurement accuracy and detection depth by adjusting button 12 according to different exploration needs, making the electrical resistivity meter adaptable to complex and ever-changing exploration environments. A rotating shaft 13 is fixedly connected to the top rear side of the electrical resistivity meter body 1. Through the rotating shaft 13, the cover plate 14 can rotate around it to realize the opening and closing protection of the screen 15 and keyboard 11. When the electrical resistivity meter is not in use, the cover plate 14 can be closed to prevent dust and debris from entering and protect the equipment. The cover plate 14 is fixedly connected to the outside of the rotating shaft 13. The cover plate 14 can protect the screen 15 and keyboard 11. It can be opened when the electrical resistivity meter is in use for convenient operation; when not in use, it can be closed to prevent dust, water stains, etc. from damaging the screen 15 and keyboard 11 and extend the service life of the equipment. The screen 15 is fixedly connected to the front side of the cover plate 14. The screen 15 is used to display various data, images and operation interfaces in real time during the exploration process, so that operators can intuitively understand the working status and measurement results of the electrical resistivity meter and provide clear data display for mineral exploration.
[0039] Specifically, the keyboard 11 on the top of the electrical resistivity meter body 1 provides operators with a convenient channel for command input and parameter setting, enabling rapid control of the electrical resistivity meter's functions and efficient acquisition and processing of exploration data. The internal adjustment buttons 12 allow for fine-tuning of various functional parameters to meet the personalized needs of different exploration environments, enhancing the adaptability of the electrical resistivity meter. The rotating shaft 13 on the rear top, in conjunction with the cover plate 14, opens when the electrical resistivity meter is in use for easy operation and closes when not in use, forming a protective barrier against dust and water damage, protecting the screen 15 and keyboard 11. The screen 15 displays various data and the operating interface in real time, intuitively presenting the working status and measurement results of the electrical resistivity meter. The coordinated operation of all components not only achieves convenient operation, functional flexibility, and environmental adaptability of the electrical resistivity meter, but also ensures stable operation of the equipment through protective design.
[0040] Reference Figure 1 , Figure 2 and Figure 4 The collection mechanism 4 includes a miniature fan 41. The bottom of the miniature fan 41 is fixedly connected to the top inner wall of the body 1 of the electrical resistivity meter. The input end of the miniature fan 41 is fixedly connected to a connecting pipe 42. The other end of the connecting pipe 42 is fixedly connected to a dust collection box 43. One end of the connecting pipe 42 is connected to the input end of the miniature fan 41, and the other end is connected to the dust collection box 43. It is used to transport dust and other impurities and acts as a pipeline connection to ensure that dust can be smoothly sucked into the miniature fan 41 from the dust collection box 43, thus ensuring the continuity of the operation of the collection mechanism 4. The rear side of the dust collection box 43 is fixedly connected to the outside of the sliding guide frame 34. The rear side of the dust collection box 43 is fixed to the outside of the sliding guide frame 34 and is used to collect the dust swept down by the soft brush 36. During the movement of the sliding guide frame 34, the dust collection box 43 follows its movement, promptly sucking in dust to prevent it from falling back onto the screen 15 or contaminating the inside of the electrophysiological instrument. The output end of the miniature fan 41 is fixedly connected to the dust outlet pipe 44, and the outside of the dust outlet pipe 44 is detachably connected to the collection box 45. The miniature fan 41 generates suction to draw dust and other impurities from the dust collection box 43 through the connecting pipe 42 and discharges them through the dust outlet pipe 44 to the collection box 45, thereby achieving dust collection and treatment and keeping the working environment clean. Two positioning bolts 46 are threadedly connected to both the front and rear sides of the collection box 45. The positioning bolts 46 are threadedly connected to the front and rear sides of the collection box 45 and the inside of the electrophysiological instrument body 1, serving to fix the collection box 45. By tightening or loosening the positioning bolts 46, the collection box 45 can be installed and disassembled, making it convenient to clean and maintain the collection box 45. A filter screen 47 is fixedly connected to the left side of the collection box 45. The external part of the positioning bolts 46 is detachably connected to the inside of the electrical resistivity meter body 1. The filter screen 47 can filter dust and other impurities, preventing them from escaping from the left side of the collection box 45, ensuring that the dust is effectively collected in the collection box 45, avoiding secondary pollution, and also protecting components such as the miniature fan 41 from dust damage.
[0041] Specifically, the collection mechanism 4 uses a micro fan 41 to provide suction, which draws in the dust collected by the dust collection box 43 and cleaned by the soft brush 36 through the connecting pipe 42. The dust is then discharged into the collection box 45 through the dust outlet pipe 44. The filter screen 47 prevents dust from escaping, and the positioning bolts 46 facilitate the disassembly and cleaning of the collection box 45. The dust collection box 43 moves synchronously with the sliding guide frame 34, collecting dust in real time and avoiding secondary pollution. This achieves efficient collection, centralized processing, and convenient cleaning of dust during the dust removal process of the electrical resistivity meter screen 15, keeping the inside of the equipment clean, protecting key components such as the fan, extending the service life of the equipment, and ensuring the stable operation of the electrical resistivity meter in the harsh environment of deep mining exploration.
[0042] Working principle: The main body 1 of the electrical resistivity meter is used to realize various functions of deep exploration. The keyboard 11 and adjustment buttons 12 can be used to operate the instrument and set parameters. The cover plate 14 rotates around the rotating shaft 13. After opening, the screen 15 displays relevant data and information.
[0043] When dust accumulates on the surface of the screen 15, the dust removal mechanism 3 is activated. The motor 31 drives the rotating plate 32 to rotate, and the rotating plate 32 drives the fixed rod 33 to move in the inner cavity 35 of the sliding guide frame 34, so that the sliding guide frame 34 slides up and down in the square opening 37. The soft brush 36 on its front inner wall continuously wipes the surface of the screen 15 to remove dust.
[0044] At the same time, the collection mechanism 4 works in concert. The micro fan 41 draws air out of the dust collection box 43 through the connecting pipe 42 to form a negative pressure. The dust collection box 43 sucks in the dust wiped off by the soft brush 36. The air and dust enter the collection box 45 through the dust outlet pipe 44 after passing through the micro fan 41. The filter screen 47 blocks the dust, and the purified air is discharged. The positioning bolt 46 can fix the collection box 45, which is convenient for disassembly and cleaning of dust.
