[0009] Preferably, the mounting assembly includes an insertion seat fixedly connected to the side end of the air inlet box. A blocking plate is slidably connected to the inner wall of the insertion seat. The side end of the blocking plate is in close contact with and abuts against the mounting frame. The mounting assembly can block the mounting frame and the drying box, thereby enhancing the sealing effect.

[0010] Preferably, a rubber pad is fixedly connected to the inner side wall of the insertion seat. The rubber pad is in interference fit with the blocking plate, which can prevent the blocking plate from easily coming off.

[0011] Preferably, a dovetail chute is formed at the side end of the mounting frame. A first dovetail slider is fixedly connected to the side end of the blocking plate.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4 shown, a data transceiver device for downhole sensors includes: a mounting box 1, a transmission circuit board 2 fixedly connected to the inner wall of the mounting box 1, and a chassis 3 disposed below the mounting box 1; a drying mechanism 4 for drying the air entering the mounting box 1 is disposed on one side of the mounting box 1; a buffer damping assembly 5 for buffering and damping during placement is disposed below the mounting box 1; wherein, the drying mechanism 4 includes a contact adsorption assembly 401 disposed on one side of the mounting box 1, and a mounting assembly 402 is disposed on one side of the contact adsorption assembly 401. When the device is used, it can be connected and installed through the chassis 3, information can be transmitted and received through the transmission circuit board 2, and the connecting wire harness of the transmission circuit board 2 extends out from the lower side of the mounting box 1 and extends out through the clearance of the chassis 3, which is convenient for installation. The air entering the mounting box 1 can be dried through the drying mechanism 4, and the impact received by the transmission circuit board 2 can be buffered and shock-absorbed through the buffer damping assembly 5, so that the service life of the transmission circuit board 2 is longer. The transmission circuit board 2 can receive the data obtained by the downhole sensors. For those skilled in the art, the transmission circuit board 2 is a prior art and will not be elaborated here.

[0024] AsFigure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the contact adsorption component 401 includes an air inlet box 4011 fixedly connected to the ventilation opening of the installation box 1. An installation frame 4012 is slidably connected to the inner wall of the air inlet box 4011. A drying box 4013 is fixedly connected to the inner wall of the installation frame 4012. When air enters the installation box 1 through the ventilation opening of the installation box 1, the air contacts the drying box 4013 at this time for moisture absorption and drying, so that the moisture content of the air contacting the transmission circuit board 2 inside the installation box 1 is reduced, preventing the transmission circuit board 2 from being damaged by contacting moisture. There are two drying boxes 4013 and they are parallel to each other. The connection openings of the drying boxes 4013 and the installation frame 4012 are arranged staggeredly. When air enters the installation frame 4012, due to the arrangement of the drying boxes 4013 at this time, the air turns and flows in the installation frame 4012, greatly increasing the absorption time and contact area of the drying boxes 4013, and increasing the moisture absorption and drying effect. Rubber drying balls can be placed inside the air inlet box 4011 to absorb moisture.

[0025] As Figure 3 and Figure 4As shown, the installation component 402 includes an insertion seat 4021 fixedly connected to the side end of the air inlet box 4011. A blocking plate 4026 is slidably connected to the inner wall of the insertion seat 4021. The side end of the blocking plate 4026 is in fit and abutment with the installation frame 4012. After the installation frame 4012 is installed, it is likely to become detached. At this time, the blocking plate 4026 blocks the installation frame 4012, making it difficult for the installation frame 4012 to enter the blocking plate 4026 and become detached, which is more stable. A rubber pad 4025 is fixedly connected to the inner side wall of the insertion seat 4021. The rubber pad 4025 is in interference fit with the blocking plate 4026. Through the interference connection between the rubber pad 4025 and the blocking plate 4026, a damping effect can be formed to prevent the fit and abutment of the blocking plate 4026 from becoming detached. A dovetail chute 4023 is formed at the side end of the installation frame 4012. A first dovetail slider 4022 is fixedly connected to the side end of the blocking plate 4026. The dovetail chute 4023 is in sliding fit with the first dovetail slider 4022. When the blocking plate 4026 slides on one side of the installation frame 4012, the installation frame 4012 is likely to shake, affecting the sealing effect. Through the sliding fit between the dovetail chute 4023 and the first dovetail slider 4022, the installation frame 4012 is not likely to shake and is more stable. A second dovetail slider 4024 is fixedly connected to the lower end of the blocking plate 4026. The second dovetail slider 4024 is in sliding fit with the inner wall of the dovetail chute 4023. It is not easy to extract the installation frame 4012 from the air inlet box 4011, and the replacement is relatively troublesome. By sliding the second dovetail slider 4024 into the dovetail chute 4023, the blocking plate 4026 can be pulled at this time to extract and replace the installation frame 4012, which is more convenient. Springs 501 and damping telescopic rods 502 are fixedly connected to the lower end of the installation box 1. The lower ends of the springs 501 and the damping telescopic rods 502 are both fixedly connected to the chassis 3. A shielding cover 503 is fixedly connected to the lower end of the installation box 1. The shielding cover 503 is in fit with the surface of the chassis 3. When the surface of the installation box 1 is impacted, the spring 501 is compressed at this time to absorb the impact force. The damping telescopic rod 502 can damp the spring 501 to prevent the spring 501 from shaking due to rapid compression and relaxation.

[0026] When the utility model is in use, when air enters the installation box 1 through the ventilation opening of the air installation box 1, the air contacts the drying box 4013 at this time for moisture absorption and drying, so that the moisture content of the air inside the installation box 1 in contact with the transmission circuit board 2 is reduced, preventing the transmission circuit board 2 from being damaged by contacting moisture. When the installation frame 4012 is installed, it is likely to become detached. At this time, the blocking plate 4026 is inserted into the insertion seat 4021 to block the installation frame 4012, so that it is not easy for the installation frame 4012 to become detached when it enters the blocking plate 4026, making it more stable. When disassembling, the blocking plate 4026 is pulled out, and then the second dovetail slider 4024 is inserted into the dovetail chute 4023 to pull the blocking plate 4026, and the installation frame 4012 can be pulled out for replacement, which is more convenient. When the surface of the installation box 1 is impacted, the spring 501 is compressed at this time to absorb the impact force. The damping telescopic rod 502 can damp the spring 501 to prevent the spring 501 from shaking due to rapid compression and relaxation. At this time, the internal transmission circuit board 2 is protected by this device, reducing the damage of the transmission circuit board 2 in the underground environment and increasing the service life.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
