Description

Technical Field

[0001] This utility model relates to the field of combined antenna technology, specifically a combined airtight antenna for underground 4G and GPS. Background Technology

[0002] As is well known, in underground operations, mobile or fixed observation devices are typically installed underground to collect information about the underground work scene in real time and transmit it to the surface via transceivers. This allows people to understand the underground work situation in a timely manner. 4G antennas can support high-definition voice calls, video monitoring, and real-time transmission of sensor data, enabling two-way communication between the ground and the underground. GPS antennas can receive BeiDou / GPS satellite signals to provide initial position references for underground equipment.

[0003] For example, the utility model patent with application publication number CN221080365U, application publication date June 4, 2024, and title "A Flat Panel Antenna for Use in Mines" has a specific structure including a base plate, on which a wiring board, a transceiver unit capable of receiving signals in different frequency bands, and several cable positioning components are provided. Each of the cable positioning components can fix a cable, and each of the cables can pass through the base plate and be electrically connected to a transceiver unit or a wiring board. The base plate is covered with an insulating shell.

[0004] The shortcoming of the existing technology is that, by passing the cable through the mounting ring through the insulating shell to make an electrical connection with the internal oscillator assembly, the mounting ring can only limit and fix the cable axially and radially. However, the underground environment is relatively humid, and external moisture can easily enter the insulating shell from the mounting ring along the surface of the cable, thereby causing short circuit damage inside the shell. Utility Model Content

[0005] The purpose of this invention is to provide a combined airtight antenna for 4G and GPS in wells, in order to overcome the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a downhole 4G and GPS dual-in-one airtight combination antenna, including a housing, a GPS antenna and a 4G antenna, and a screw sleeve rod fixedly disposed on the housing. The GPS antenna and the 4G antenna pass through the screw sleeve rod and are electrically connected to the housing. A rubber column that wraps around the GPS antenna and the 4G antenna is fixedly disposed inside the screw sleeve rod.

[0007] As a further description of the above technical solution: it also includes a first sealing ring, a second sealing ring, and a nut, wherein the diameter of the first sealing ring is larger than that of the second sealing ring, the nut is threaded onto the threaded sleeve rod and presses the first sealing ring and the second sealing ring onto the housing, and the first sealing ring is located between the second sealing ring and the nut.

[0008] As a further description of the above technical solution: the housing has an inner groove coaxial with the screw rod, and the outer ring side of the inner groove is an inner slope surface.

[0009] As a further description of the above technical solution: the inner groove is provided with an annular protrusion that is aligned with the inner ring side of the second sealing ring.

[0010] As a further description of the above technical solution: a ring groove is provided on the first side of the first sealing ring, which is aligned with the outer ring of the second sealing ring.

[0011] As a further description of the above technical solution: the first side of the nut is provided with an indentation groove facing the first sealing ring.

[0012] As a further description of the above technical solution: the threaded rod is made of stainless steel.

[0013] As a further description of the above technical solution: the nut is made of stainless steel.

[0014] As a further description of the above technical solution: the first sealing ring is made of perfluoroether rubber.

[0015] As a further description of the above technical solution: the second sealing ring is made of perfluoroether rubber.

[0016] In the above technical solution, the present invention provides an airtight combination antenna for 4G and GPS in wells. It uses a rubber column inside the screw sleeve to wrap the two antennas to seal and wrap the inside of the screw sleeve, thereby improving the sealing line between the inside of the screw sleeve and the antenna, preventing external moisture from entering the inside of the housing along the inside of the screw sleeve and the surface of the antenna, and improving the protection of the circuit inside the housing.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figure 1 and Figure 2 As shown, this embodiment improves the connection between the housing 1 and the antenna based on the original antenna. Specifically, a threaded rod 2 for the antenna to pass through is added to the housing 1, through which the GPS antenna 31 and the 4G antenna 32 extend into the housing 1. A rubber post 4 is set inside the threaded rod 2 to seal and wrap the two antennas, thereby improving the sealing line between the inside of the threaded rod 2 and the antenna, preventing external moisture from entering the inside of the housing 1 along the inside of the threaded rod 2 and the antenna surface, and improving the protection of the circuit inside the housing 1.

[0028] Specifically, a GPS module and a 4G module are provided inside the housing 1. The GPS antenna 31 and the 4G antenna 32 are electrically connected to the GPS module and the 4G module, respectively. The GPS module and the 4G module are common technical knowledge known to those skilled in the art, and will not be described in detail here.

[0029] In the above technical solution, the inner side of the screw sleeve rod 2 is sealed and wrapped with glue pillars 4 that wrap the two antennas, thereby improving the sealing line between the inner side of the screw sleeve rod 2 and the antenna, preventing external moisture from entering the inner side of the housing 1 along the inner side of the screw sleeve rod 2 and the antenna surface, and improving the protection of the circuit inside the housing 1.

[0030] Example 2

[0031] Combination Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides an additional sealing structure based on embodiment one. Specifically, the first sealing ring 5 and the second sealing ring 6 are pressed onto the housing 1 by the nut 7. This further seals and protects the connection between the housing 1 and the threaded rod 2 by the first sealing ring 5 and the second sealing ring 6. The diameter of the first sealing ring 5 is larger than that of the second sealing ring 6. When the nut 7 presses the first sealing ring 5, the outer ring side of the first sealing ring 5 deforms and approaches the surface of the housing 1, thus allowing the first sealing ring 5 to be located outside the second sealing ring 6 and form a protective shield. At this time, the first sealing ring 5 and the second sealing ring 6 achieve double-layer sealing protection for the connection between the housing 1 and the threaded rod 2.

[0032] Example 3

[0033] Combination Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further improves the housing 1 based on embodiment 2 by creating an inner groove 11 on the housing 1. When the nut 7 presses the first sealing ring 5 and the second sealing ring 6 onto the threaded rod 2, the first sealing ring 5 is pressed into the inner groove 11, and the outer side of the second sealing ring 6 is deformed and extended into the inner groove 11 by the pressure of the nut 7, so that the outer side of the second sealing ring 6 abuts against the inner slope surface 13 of the inner groove 11. At this time, the first sealing ring 5 presses and seals the inner groove 11, so that the inner groove 11 forms a sealed buffer space on the outer side of the connection between the threaded rod 2 and the housing 1, thereby further preventing external moisture from entering the inner side of the housing 1 and improving the protection of the antenna module inside the housing 1.

[0034] Example 4

[0035] Combination Figure 2 and Figure 4 As shown, this embodiment further improves the housing 1 based on embodiment 3. Specifically, an annular protrusion 12 is provided in the inner groove 11. When the nut 7 presses the first sealing ring 5 and the second sealing ring 6 onto the threaded sleeve rod 2, the annular protrusion 12 will also squeeze the inner ring side of the second sealing ring 6. This causes the annular protrusion 12 to apply deformation pressure to the inner ring side of the first sealing ring 5 and the second sealing ring 6, thereby allowing the inner ring side of the second sealing ring 6 to deform and extend into the threaded connection between the nut 7 and the threaded sleeve rod 2. This further locks and reinforces the already locked nut 7, improving the fixing stability of the nut 7 on the first sealing ring 5 and the second sealing ring 6.

[0036] Example 5

[0037] Combination Figure 3 and Figure 4As shown, this embodiment further improves the housing 1 based on embodiment four. Specifically, an annular groove 51 is provided on the side of the first sealing ring 5 facing the nut 7. When the nut 7 presses and fixes the first sealing ring 5 and the second sealing ring 6, the presence of the annular groove 51 facilitates the deformation of the outer ring side of the first sealing ring 5 towards the housing 1 side, thereby improving the sealing stability of the first sealing ring 5 on the inner groove 11.

[0038] Specifically, such as Figure 3 As shown, the side of the first sealing ring 5 facing the nut 7 is the first side.

[0039] Example 6

[0040] Combination Figure 3 and Figure 4 As shown, this embodiment further improves the nut 7 based on embodiment five. Specifically, an inner groove 71 is formed on the side of the nut 7 near the first sealing ring 5. When the nut 7 is used to press and fix the first sealing ring 5 and the second sealing ring 6, the inner ring side of the first sealing ring 5 can deform and enter the inner groove 71, thereby improving the fixing stability between the nut 7 and the first sealing ring 5. This also facilitates the first sealing ring 5 to deform and extend into the connection between the nut 7 and the threaded rod 2 to further lock and reinforce the nut 7.

[0041] Specifically, the side of the nut 7 facing the first sealing ring 5 is the first side.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
