Description

Technical Field

[0001] This utility model relates to the field of mineral exploration instruments, and in particular to a portable rapid detection instrument for geological structures in coal mines. Background Technology

[0002] In coal mining operations, accurate detection of geological structures is crucial for ensuring safe production and improving mining efficiency. Electromagnetic methods, as an important geophysical exploration technique, utilize the difference in electrical conductivity and magnetic permeability of ores, employing the principle of electromagnetic induction for mineral exploration, and have been widely applied in the field of coal mine geological structure detection.

[0003] Authorization announcement number CN216619111U discloses a portable prospecting instrument, relating to the field of prospecting instruments. It includes a main body, with a fixing ring fixedly installed on the inner wall and at the top edge of the main body. An adjustment mechanism is provided inside the main body and below the fixing ring. The instrument can be unfolded from its protective device for detection during use. However, it has shortcomings in practical applications. Due to the complex environment of underground coal mines, various metal pipes, cables, and supports are widely distributed. When the probe is unfolded and exposed, the instrument's electromagnetic signals are easily interfered with by surrounding metal objects, causing electromagnetic signal superposition and interference, severely affecting the accuracy of the signal and distorting the detection data. It cannot accurately reflect the true shape, location, and scale of geological structures, leading to deviations or even errors in the detection results.

[0004] Therefore, there is an urgent need to develop a portable instrument that can effectively avoid probe exposure and reduce interference from surrounding metal objects, thereby enabling rapid and accurate detection of coal mine geological structures. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the aforementioned portable rapid detection instrument for coal mine geological structures, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable rapid coal mine geological structure detector, including a protective box with an open bottom;

[0008] The mounting frame, located inside the protective box, consists of two vertical flanges and a web connecting the two flanges, and the mounting frame can slide vertically to the outside of the opening;

[0009] The main body of the prospecting instrument is mounted through the web plate, with its probe pointing vertically downwards;

[0010] A pair of cover plates are hinged to the opposite side walls of the protective box, which can close the opening on the protective box when closed.

[0011] Inner lining plate, located on the inner side wall of the cover plate;

[0012] Multiple connecting rods are hinged between the web and the corresponding inner lining plate;

[0013] When the two cover plates are unfolded to be parallel to the side wall of the protective box, the connecting rod is controlled by its rotation to pull the mounting frame down, and the two flanges of the mounting frame and the pair of cover plates form a rectangular shielding cavity that encloses the probe of the prospecting instrument.

[0014] In a preferred embodiment of the portable rapid coal mine geological structure detector of this utility model, when the cover plate is unfolded to be parallel to the side wall of the protective box, the bottom of the web plate is attached to the top of the two inner lining plates, thereby sealing the top of the shielding cavity.

[0015] As a preferred embodiment of the portable coal mine geological structure rapid detection instrument of this utility model, when the cover plate is unfolded to be parallel to the side wall of the protective box, the bottom surface of the two flanges of the mounting frame is coplanar with the bottom surface of the cover plate.

[0016] In a preferred embodiment of the portable rapid coal mine geological structure detector of this utility model, when the cover plate is unfolded to be parallel to the side wall of the protective box, a heat dissipation zone is formed between the top of the detector body and the inner top wall of the protective box.

[0017] As a preferred embodiment of the portable coal mine geological structure rapid detection instrument of this utility model, when the cover plate is unfolded to be parallel to the side wall of the protective box, the relative positions of the two are locked by the first latch.

[0018] As a preferred embodiment of the portable coal mine geological structure rapid detection instrument of this utility model, when the cover plate is closed to seal the opening of the protective box, the relative positions of the two are locked by the second latch.

[0019] The beneficial effects of this utility model are as follows: The protective case can store the prospecting instrument, making it easy to carry and preventing damage from collisions during transportation. Simultaneously, the mounting frame, which extends synchronously with the rotating cover, allows the prospecting instrument to be lowered outside the protective case. Furthermore, the shielding cavity between the mounting frame and the cover reduces interference from surrounding metal objects, thereby improving detection accuracy and accurately reflecting the true shape, location, and scale of geological structures.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0030] Reference Figures 1-4 As one embodiment of this utility model, a portable rapid coal mine geological structure detector is provided, which includes a protective case 1 with an open bottom, serving as the main outer shell of the detector and providing installation space and protection for other internal components. It can protect internal components such as the detector body 3 from damage caused by external factors such as impacts and dust.

[0031] Mounting bracket 2, located inside protective case 1, consists of two vertical flanges and a web connecting the two flanges, forming an "H" shape. The two flanges are attached to the inner wall of protective case 1. Mounting bracket 2 can slide vertically to the outside of the opening. During operation, it can move the prospecting instrument body 3 to a suitable detection position, improving the accuracy and convenience of detection. When stored, it can store the prospecting instrument body 3 inside protective case 1, enhancing the portability and protection of the instrument.

[0032] The main body 3 of the prospecting instrument is installed through the web plate. It is the core component of the entire detector and is used to transmit and receive electromagnetic signals. By analyzing the electromagnetic signals, it can detect the geological structure of the coal mine. Its probe is vertically downward to ensure accurate detection of the geological conditions below.

[0033] A pair of cover plates 4 are hinged to the opposite side walls of the protective box 1, and when they are closed, they can close the opening on the protective box 1; the inner lining plate 41 is provided on the inner side wall of the cover plate 4.

[0034] Multiple connecting rods 5 are hinged between the web plate and the corresponding inner lining plate 41, realizing the linkage between the cover plate 4 and the mounting frame 2. This makes the switching between the working and storage states of the instrument more automated and convenient, eliminating the need for manual operation of the lifting and lowering of the mounting frame 2, thus improving the efficiency and convenience of instrument operation.

[0035] When the two cover plates 4 are unfolded to be parallel to the side wall of the protective box 1, the connecting rod 5 is rotated to pull the mounting frame 2 down, so that the bottom surface of the two side flanges of the mounting frame 2 is coplanar with the bottom surface of the cover plate 4, which facilitates its stable ground contact and improves placement stability. The two side flanges of the mounting frame 2 and the pair of cover plates 4 form a rectangular shielding cavity that encloses the probe of the prospector body 3. The bottom of the web plate is attached to the top of the two inner lining plates 41, so that the top of the shielding cavity is sealed. The rectangular shielding cavity can reduce the interference of surrounding metal objects on the prospector body 3, thereby improving the detection accuracy and accurately reflecting the true shape, location and scale of the geological structure.

[0036] Conductive materials (such as copper mesh) can be embedded in the outer sides of the flanges on both sides of the mounting bracket 2 and the pair of cover plates 4, and a grounding effect can be formed after contact with the ground to absorb external electromagnetic interference.

[0037] In addition, when the cover plate 4 is unfolded to be parallel to the side wall of the protective box 1, a heat dissipation area is formed between the top of the prospector body 3 and the inner top wall of the protective box 1. It should be noted that in order to make the whole device easy to carry, the internal design of the protective box 1 is relatively compact, and the gap between the prospector body 3 and other electrical components is small. By lowering the prospector body 3 by a certain distance, the gap between it and other electrical components can be increased, thereby facilitating the internal fan (not shown in the figure) to dissipate heat, avoiding the problem of electrical components being too concentrated and heat dissipation efficiency, and ensuring the stable operation of the prospector body 3.

[0038] When the cover plate 4 is unfolded to be parallel to the side wall of the protective box 1, the relative positions of the two are locked by the first latch 6a; when the cover plate 4 is closed to seal the opening of the protective box 1, the relative positions of the two are locked by the second latch 6b; the first latch 6a and the second latch 6b ensure the stability and reliability of the instrument under different working conditions, prevent the accuracy of the detection work from being affected by the change of the position of the cover plate 4 or cause damage to the internal components, and further improve the safety and service life of the instrument.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
