Description

Technical Field

[0001] This utility model relates to the field of geological exploration, specifically a protective device for a downhole transient electromagnetic instrument. Background Technology

[0002] Transient electromagnetic instruments can detect geological anomalies in coal mines, such as faults, fracture zones, collapse columns, water-filled karst caves, and karst development areas. By analyzing the electrical characteristics of these geological structures, their spatial distribution and water content can be revealed, thus providing important information for safe production in mines. Therefore, this instrument is quite precise and valuable, and must be protected against drops, impacts, water, and static electricity.

[0003] However, transient electromagnetic instruments face extremely harsh working environments during downhole geophysical exploration operations. The confined space underground makes the instruments susceptible to collisions and scratches from surrounding rocks and tools. For example, during tunnel excavation, the instrument unit may be scratched by contact with protruding rock sections, damaging the casing and consequently affecting the normal operation of internal precision circuits and sensors.

[0004] Meanwhile, the underground environment is humid with high air humidity, and a large amount of water vapor is diffused in the air. This moisture can easily enter the instrument through gaps and interfaces, causing problems such as short circuits and component corrosion. In addition, the complex electromagnetic environment underground can generate static electricity. The accumulation of static electricity may interfere with the instrument's data transmission and processing, leading to deviations in measurement results.

[0005] Currently, most instruments lack protective casings and have extremely limited protective capabilities, failing to fully and effectively protect downhole geophysical exploration instruments. This affects the normal operation of downhole geophysical exploration instruments and reduces their service life. Therefore, it is necessary to take necessary protective measures for the instruments. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a protective device for a downhole transient electromagnetic instrument. The device has a novel design and reasonable structure, including an integrally formed wear-resistant layer and an anti-static layer, which comprehensively improves the protection capability of the downhole transient electromagnetic instrument host and ensures that the instrument host operates stably and reliably in harsh downhole environments.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model includes a housing that corresponds to the shape of the instrument host and is disposed on the outer periphery of the instrument host. The housing includes an integrally formed wear-resistant layer and an antistatic layer. The antistatic layer is disposed inside the wear-resistant layer. The housing is made of a composite silicone material, which includes a silicone material for forming the wear-resistant layer and an antistatic silicone material for forming the antistatic layer.

[0009] A further improvement of this utility model is that the housing includes a carrier and an upper cover disposed above the carrier and movably connected to the carrier.

[0010] A further improvement of this utility model is that the carrier and the top cover are connected together by a waterproof zipper.

[0011] A further improvement of this utility model is that a sealing plug is provided on the carrier at the location corresponding to the instrument interface, and the sealing plug is made of silicone material.

[0012] A further improvement of this utility model is that a base is provided below the carrier, and the thickness of the base is greater than the thickness of the side wall of the carrier.

[0013] A further improvement of this utility model is that a storage bag is provided on the side of the carrier.

[0014] A further improvement of this utility model is that the housing is provided with reflective strips.

[0015] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0016] This utility model features a simple structure and novel design. The one-piece molded housing, composed of a wear-resistant layer and an anti-static layer, not only provides necessary physical and anti-static protection for the downhole transient electromagnetic instrument host, but also, due to its seamless silicone structure, offers a degree of waterproof and dustproof protection, achieving a high protection rating of at least IP67. This significantly enhances the instrument host's adaptability to harsh environments, ensuring the normal operation of the downhole geophysical instrument, guaranteeing work progress, and extending the instrument host's service life. Attached Figure Description

[0017] Figure 1 This is a three-dimensional structural schematic diagram of the present invention;

[0018] Figure 2 This is a cross-sectional structural diagram of the shell of this utility model.

[0019] The components include: 1. Shell; 1-1. Wear-resistant layer; 1-2. Antistatic layer; 2. Storage bag; 3. Top cover; 4. Waterproof zipper; 5. Sealing plug; 6. Carrier; 7. Reflective strip; 8. Base. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to embodiments:

[0021] A protective device for a downhole transient electromagnetic instrument, such as Figure 1-2As shown, it includes a housing 1 that corresponds to the shape of the main instrument unit and is disposed on the outer periphery of the main instrument unit. The housing 1 is made of composite silicone material and provides effective protection for the instrument inside the housing 1. It is precisely designed according to the size and shape of the downhole transient electromagnetic instrument main unit to ensure that the housing 1 fits perfectly with the main instrument unit without affecting the operation and use of the instrument. At the same time, various interfaces, buttons, displays, and other positions for the instrument are reserved on the housing 1 for convenient user operation. These reserved positions are also waterproofed and sealed, ensuring both normal use of the instrument and a good sealing effect, truly achieving waterproof and dustproof performance.

[0022] First, a high-precision mold is fabricated based on the size and shape of the instrument's main unit. The prepared silicone material is injected into the outer cavity of the mold and cured at high temperature to form a wear-resistant layer 1-1. Then, antistatic silicone material is injected into the inner cavity of the mold, completing the preparation of the antistatic layer 1-2 of the shell 1. Figure 2 As shown, the housing 1 includes an integrally formed wear-resistant layer 1-1 and an antistatic layer 1-2. The antistatic layer 1-2 is disposed inside the wear-resistant layer 1-1. The wear-resistant layer 1-1 is made of silicone material, specifically solid silicone, which has excellent wear resistance and can maintain material stability for a long time in harsh environments. This wear-resistant layer 1-1 can resist external scratches and impacts, effectively resisting scratches from sharp objects and reducing wear. When the instrument is subjected to impact, the wear-resistant layer 1-1 made of silicone material can absorb energy, disperse the impact force, and reduce the impact on the main unit of the instrument. Therefore, the wear-resistant layer 1-1 enhances the hardness and wear resistance of the protective shell surface, resisting the wear of the protective shell by sand, rocks, etc. in the underground environment.

[0023] The inner antistatic layer 1-2 is tightly fitted to the instrument main unit, possessing excellent insulation properties. This prevents electromagnetic interference and avoids safety accidents caused by leakage. It provides stable support and protection, preventing the protective shell from sliding or shaking on the instrument. The antistatic layer 1-2 is made of antistatic silicone material, specifically a high-resilience solid silicone material with high resilience and stable antistatic effect. The antistatic layer 1-2 effectively avoids electrostatic interference, ensuring the accuracy of data transmission and processing, and improving the stability of instrument operation.

[0024] like Figure 1As shown, the housing 1 includes a support body 6 and an upper cover 3 movably connected to the support body 6, located above it. The support body 6 and the upper cover 3 are connected together by a waterproof zipper 4. The upper cover 3 and the waterproof zipper 4 ensure that the instrument main unit can be easily placed into or removed from the housing 1. The waterproof zipper 4 ensures that the support body 6 and the upper cover 3 form a closed housing 1. This provides physical and electrostatic protection for the downhole transient electromagnetic instrument main unit. The seamless silicone integrated structure of the housing 1 provides a certain degree of waterproofing and dustproofing for the instrument main unit, comprehensively improving its adaptability to harsh environments.

[0025] After the housing 1 is formed, a sealing plug 5 corresponding to the instrument interface is installed. The sealing plug 5 is set on the carrier 6 at the position corresponding to the instrument interface, and the sealing plug 5 is made of silicone material. The sealing plug 5 is customized according to the shape and size of the instrument interface, and a waterproof coating is applied to the edge of the sealing plug 5. Then, the sealing plug 5 is installed at the instrument interface, ensuring that the sealing plug 5 can flexibly retract and pop out, and that the sealing plug 5 seals and blocks the instrument interface when not in use, achieving good waterproof and dustproof functions.

[0026] like Figure 1 As shown, a base 8 is provided below the support body 6. The thickness of the base 8 is greater than the thickness of the side wall of the support body 6 to ensure that the base 8 can bear the weight of the instrument host.

[0027] The side of the carrier 6 is provided with a storage bag 2, which is used to store small tools commonly used in underground operations, such as flashlights and spare batteries. The housing 1 is provided with a reflective strip 7, which makes it easy to be spotted during underground operations and prevents loss.

[0028] The housing 1 is provided with heat dissipation vents at locations corresponding to the core components inside the instrument. The heat dissipation vents facilitate the timely dissipation of heat generated during the operation of the instrument host. When the instrument host is finished, the heat dissipation vents are sealed to ensure that the instrument host is waterproof and dustproof.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are by no means intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description; it is impossible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
