Description

Technical Field

[0001] This utility model belongs to the technical field of geological exploration equipment, specifically relating to a geophysical instrument for geological exploration. Background Technology

[0002] Geological exploration refers to investigation and research work carried out within a certain area, with the main purpose of finding and evaluating mineral resources and studying geological structures and conditions.

[0003] During geological exploration, operators use high-density electrical resistivity tomography (EDT) instruments to detect electrical differences in underground geological bodies, thereby inferring their spatial distribution, morphology, and properties. By arranging a series of electrodes on the ground to supply power to the underground, an artificial electric field is created. The potential difference between different electrodes is measured, the apparent resistivity value is calculated, and an image of the underground resistivity distribution is plotted. Using this data and image, EDT instruments can identify potential ore body distribution areas in mineral geological exploration. Therefore, EDT instruments are also a type of geophysical instrument used in geological exploration. However, after using EDT instruments in relatively humid environments, some of the moisture in the environment will be trapped inside the sealed enclosure due to the closed lid. This moisture will then corrode the internal components, affecting their lifespan.

[0004] Therefore, this utility model provides a geophysical instrument for geological exploration to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a geophysical instrument for geological exploration, which aims to solve the problem that, in the existing high-density electrical resistivity tomography instrument, after use in a relatively humid environment, some of the moisture in the environment is trapped inside the box due to the closed sealing cover. This moisture will then corrode the internal components of the box, thereby affecting the service life of the internal components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geophysical instrument for geological exploration, comprising a housing, a geophysical instrument main unit embedded in the inner surface of the housing, a sealing cover hinged to the top surface of the geophysical instrument main unit, a through groove formed at the center of the top surface of the sealing cover, a mounting block connected to the bottom surface of the sealing cover outside the through groove, a placement groove formed on the front surface of the mounting block, a dehumidifying filter element slidably placed inside the placement groove, positioning blocks symmetrically connected to one end surface on both sides of the dehumidifying filter element, one end of the positioning block extending into the positioning groove, the positioning groove symmetrically formed on the front surface of the mounting block, a protrusion connected to the bottom surface of the sealing cover outside the through groove, a baffle hinged to the bottom surface of the protrusion, and a first magnetic block embedded on one side surface of the baffle.

[0007] In a preferred embodiment of the geophysical instrument for geological exploration according to this utility model, the positioning block is connected to the mounting block by means of a positioning groove.

[0008] As a preferred embodiment of the geophysical instrument for geological exploration according to this utility model, butterfly bolts are connected through both sides of the mounting block, and one end of the butterfly bolt is connected through a limiting hole. The limiting hole is opened through one side of the positioning block, and the butterfly bolt is threadedly connected to the mounting block through the limiting hole.

[0009] As a preferred embodiment of the geophysical instrument for geological exploration according to this utility model, a first sealing ring is connected around the outer surface of the front end of the dehumidifying filter element, and one end of the first sealing ring is engaged in the interior of the slot, which is located on the inner surface of the front end of the placement groove.

[0010] As a preferred embodiment of the geophysical instrument for geological exploration according to this utility model, one end surface of the first magnetic block can contact the second magnetic block, the second magnetic block is connected to one side surface of the protrusion, the other end surface of the first magnetic block can contact the third magnetic block, and the third magnetic block is connected to the bottom surface of one side of the sealed box cover.

[0011] As a preferred embodiment of the geophysical instrument for geological exploration according to this utility model, a second sealing ring is connected to the end surface of the baffle facing the sealing box cover, and the sealing box cover is snapped into the interior of the sealing groove, which is opened on the bottom surface of the protrusion.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the interplay of a through-slot, mounting block, dehumidifying filter element, positioning block, butterfly bolt, and first sealing ring. After the geophysical instrument's main unit is used and the sealed box cover is closed, the dehumidifying filter element will adsorb the air sealed inside the box through the through-slot, thus removing moisture from the air. This ensures the dryness of the internal environment of the box, prevents moisture from corroding the internal components, and ensures the service life of the internal components.

[0014] This invention utilizes the cooperation of a protrusion, a baffle, and a second sealing ring. When the sealed box cover is opened on the box body, the baffle on the protrusion can be rotated, causing the first and second magnetic blocks on the baffle to attract each other. At this time, the position of the baffle will be fixed on the protrusion, and the second sealing ring on the baffle will engage with the sealing groove, forming a relatively sealed space inside the protrusion. This prevents external air from continuously contacting the dehumidifying filter element through the groove, thereby ensuring the service life of the dehumidifying filter element.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5The present invention provides the following technical solution: a geophysical instrument for geological exploration, comprising a housing 1, a geophysical instrument host 2 embedded in the inner surface of the housing 1, a sealing cover 3 hinged to the top surface of the geophysical instrument host 2, a through groove 4 opened in the middle of the top surface of the sealing cover 3, a mounting block 5 connected to the bottom surface of the sealing cover 3 outside the through groove 4, a placement groove 6 opened in the front surface of the mounting block 5, a dehumidifying filter element 7 slidably placed inside the placement groove 6, a positioning block 8 symmetrically connected to one end surface on both sides of the dehumidifying filter element 7, one end of the positioning block 8 extending into the positioning groove 9, the positioning groove 9 symmetrically opened on the front surface of the mounting block 5, a protrusion 14 connected to the bottom surface of the sealing cover 3 outside the through groove 4, a baffle 15 hinged to the bottom surface of the protrusion 14, and a first magnetic block 16 embedded in one side surface of the baffle 15.

[0024] Preferably, the positioning block 8 is slidably connected to the mounting block 5 via the positioning groove 9.

[0025] In actual use, the positioning block 8 can slide in the positioning groove 9 on the mounting block 5. When the dehumidifying filter element 7 is slid into the placement groove 6, the positioning block 8 will also slide into the positioning groove 9. When the dehumidifying filter element 7 is slid out of the placement groove 6, the positioning block 8 will also slide out of the positioning groove 9.

[0026] Preferably, butterfly bolts 10 are connected through both sides of the mounting block 5, and one end of the butterfly bolt 10 is connected through a limiting hole 11. The limiting hole 11 is opened through one side of the positioning block 8, and the butterfly bolt 10 is threadedly connected to the mounting block 5 through the limiting hole 11.

[0027] In practical use, when the dehumidifying filter element 7 is slidably placed into the placement groove 6, the positioning block 8 on the dehumidifying filter element 7 will also slide into the positioning groove 9 on the mounting block 5. At this time, the butterfly bolt 10 is screwed into the mounting block 5 through the limiting hole 11 on the positioning block 8, so that the position of the positioning block 8 is fixed in the positioning groove 9, and the position of the dehumidifying filter element 7 is also fixed in the placement groove 6 on the mounting block 5. When the butterfly bolt 10 is unscrewed and the dehumidifying filter element 7 is pulled, the positioning block 8 can be separated from the positioning groove 9, and the dehumidifying filter element 7 can also be slidably separated from the placement groove 6, so that the operator can maintain and replace the dehumidifying filter element 7.

[0028] Preferably, a first sealing ring 12 is connected around the outer surface of the front end of the dehumidifying filter element 7, and one end of the first sealing ring 12 is engaged in the interior of the slot 13, which is located on the inner surface of the front end of the placement slot 6.

[0029] In practical use, when the dehumidifying filter element 7 is slidably placed into the placement groove 6 on the mounting block 5, the first sealing ring 12 on the dehumidifying filter element 7 will move to the position of the slot 13, so that the first sealing ring 12 is elastically engaged in the slot 13, thereby improving the sealing between the dehumidifying filter element 7 and the mounting block 5 and preventing external air from entering the placement groove 6 through the gap between the dehumidifying filter element 7 and the mounting block 5.

[0030] Preferably, one end surface of the first magnetic block 16 can contact the second magnetic block 17, the second magnetic block 17 is connected to one side surface of the protrusion 14, the other end surface of the first magnetic block 16 can contact the third magnetic block 18, and the third magnetic block 18 is connected to the bottom surface of one side of the sealing box cover 3.

[0031] In practical use, the second magnetic block 17 and the third magnetic block 18 are matched with the first magnetic block 16. When the baffle 15 rotates on the protrusion 14 and the baffle 15 contacts the protrusion 14, the first magnetic block 16 on the baffle 15 will be attracted together with the second magnetic block 17, fixing the position of the baffle 15 on the protrusion 14. Then, if the baffle 15 is rotated 180 degrees in the opposite direction, the first magnetic block 16 on the baffle 15 will be attracted together with the third magnetic block 18, fixing the position of the baffle 15 on the sealing cover 3. At this time, the baffle 15 no longer blocks the protrusion 14, and the through groove 4 on the inner side of the protrusion 14 can be exposed. At this time, the dehumidifying filter element 7 can adsorb the moisture inside the box 1 through the through groove 4.

[0032] Preferably, a second sealing ring 19 is connected to one end surface of the baffle 15 facing the sealing box cover 3, and the sealing box cover 3 is snapped into the interior of the sealing groove 20, which is opened on the bottom surface of the protrusion 14.

[0033] In practical use, when the baffle 15 is fixed on the protrusion 14, the second sealing ring 19 on the baffle 15 will move and engage in the sealing groove 20, thereby improving the sealing between the baffle 15 and the protrusion 14, so that the baffle 15 and the protrusion 14 can block the through groove 4, forming a relatively sealed space inside the protrusion 14, preventing external air from passing through the protrusion 14 and contacting the dehumidification filter element 7 through the through groove 4.

[0034] It should be noted that the housing 1, the geophysical instrument main unit 2, and the sealing cover 3 constitute a high-density electrical resistivity meter. The high-density electrical resistivity meter model is YDG64. The housing 1 and the sealing cover 3 are connected by a snap fastener, so that the sealing cover 3 can be closed and fixed on the housing 1. The sealing cover 3 is provided with a sealing ring that can be engaged into the corresponding slot on the housing 1. When the sealing cover 3 is closed on the housing 1, a relatively sealed space is also formed inside the housing 1. The first sealing ring 12 and the second sealing ring 19 are both made of rubber. The dehumidification filter element 7 can be customized to the required shape and size for use. The position of the through groove 4 is connected to the position of the internal space of the mounting block 5.

[0035] Working principle: When using this geophysical exploration instrument, the main unit 2 of the instrument is carried to the designated location for geological exploration via the housing 1. The sealed cover 3 on the housing 1 is opened, and then the baffle 15 is rotated on the protrusion 14, causing the first magnetic block 16 and the third magnetic block 18 on the baffle 15 to separate. After the baffle 15 is rotated, the first magnetic block 16 and the second magnetic block 17 can be attracted together. At this time, the baffle 15 can be fixed on the protrusion 14. At the same time, the second sealing ring 19 on the baffle 15 will also move and engage with the sealing groove 20, so that the protrusion 14 is fixed. The part forms a relatively sealed space, which prevents external air from passing through the protrusion 14 and continuously contacting the dehumidifying filter element 7 through the through groove 4, thereby ensuring the service life of the dehumidifying filter element 7. Then, the copper electrodes are driven into the ground at equal intervals according to the designed survey line to a certain depth, and then the electrodes are connected using a multi-core cable. At this time, the other end of the multi-core cable is connected to the corresponding socket on the geophysical instrument host 2. Then, according to the geological conditions, exploration depth and instrument performance, the operating parameters such as measurement range, sampling frequency, and power supply voltage are set on the geophysical instrument host 2. After the parameters are set, the geophysical instrument host 2 can be started. The geophysical instrument main unit 2 supplies power to the underground through electrodes, forming an artificial electric field and measuring the potential difference between different electrodes to calculate the apparent resistivity value, thereby drawing an image of the underground resistivity distribution. Operators then analyze this image using specialized inversion processing software, combining it with geological data and exploration objectives to identify potential geological anomalies, such as ore bodies, water-bearing structures, and fault fracture zones. After the geophysical instrument main unit 2 has finished use, the baffle 15 is moved again, causing it to rotate on the protrusion 14, so that the first... When the first magnetic block 16 and the second magnetic block 17 are separated, the first magnetic block 16 and the third magnetic block 18 can be attracted together by rotating the baffle 15. At this time, the baffle 15 is in the open state on the protrusion 14, exposing the through groove 4. After the operator closes the sealing cover 3 on the box 1, the dehumidifying filter element 7 will adsorb the air sealed inside the box 1 through the through groove 4, so that the moisture in the air is adsorbed away, thereby ensuring the dryness of the internal environment of the box 1, preventing moisture from corroding the internal components of the box 1, and ensuring the service life of the internal components of the box 1.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
