[0025] like Figure 1 As shown in the illustration, a downhole gas monitoring terminal 10, according to a partially exemplary embodiment, includes a top cover 11, a bottom cover 12, an antenna 13, and a methane sensor 15. The top cover 11 and the bottom cover 12 are detachably and sealed together to form a cavity housing electronic components. The antenna 13 is detachably connected to the top cover 11 and / or the bottom cover 12, and electrically connected to the electronic components covered by the top cover 11 and the bottom cover 12. The methane sensor 15 penetrates the bottom cover 12 and is electrically connected to the electronic components covered by the top cover 11 and the bottom cover 12. Thus, the detachable antenna electrically connected to the top cover and / or the bottom cover greatly expands the applicable scenarios of the monitoring terminal, making it particularly suitable for use in downhole environments where installation space is complex and signal transmission is inconvenient. This effectively solves the problem of traditional gas monitoring terminals having fixed and non-adjustable antenna positions, requiring installation only at the top and not allowing optimization according to actual signal requirements, thus greatly expanding the operational possibilities of the monitoring terminal.

[0026] Optionally, the top cover 11 and the bottom cover 12 are made of cast aluminum, a corrosion-resistant material, thus possessing good corrosion resistance. Preferably, the outer surfaces of the top cover 11 and the bottom cover 12 are treated with a baked enamel finish, thereby further improving the waterproof performance of the top cover and the bottom cover, enabling the internal cavity constructed by the top cover and the bottom cover to be completely isolated from the external environment, thereby ensuring that the entire monitoring terminal can continue to operate normally under immersion conditions.

[0027] Optionally, such as Figure 1 andFigure 2 As shown, the top cover 11 and the bottom cover 12 are bolted together and are configured to move together. The top cover 11 includes a top cover housing 111, a groove 112, and at least one first antenna interface 113. The groove 112 is located on the top surface of the top cover housing 111 and extends vertically. The first antenna interface 113 penetrates the top surface of the top cover housing 111 and electrically connects to the electronic components covered by the top cover housing 111. Preferably, the first antenna interfaces 113 are spaced apart on the bottom surface of the groove 113. Therefore, by creating a groove on the top surface of the top cover housing 111, forming a break from the top surface of the top cover housing 111, and placing the first antenna interfaces 113 on the bottom surface of the groove 113, protection of the first antenna interfaces 113 is ensured, and interference with the first antenna interfaces 113 is avoided when fixing them through the top surface of the top cover housing 111. Furthermore, in order to facilitate the convenient installation of the monitoring terminal 10, at least one mounting hole 114 is also machined on the top cover housing 111, and the mounting holes 114 are spaced apart along the length direction of the top cover housing 111.

[0028] Optionally, the bottom cover 12 includes a bottom cover housing 121 and at least one second antenna interface 122. The second antenna interface 122 penetrates the bottom cover housing 121 and is electrically connected to the electronic components covered by the bottom cover 12. Thus, by providing at least one second antenna interface on the bottom cover, different installation positions are provided for antenna connection, ensuring that the monitoring terminal can easily install the antenna. This improves the overall installation flexibility of the monitoring terminal while ensuring its communication capabilities.

[0029] In the embodiments of this application, such as Figure 2 As shown, to achieve accurate monitoring of the downhole water level, a water immersion sensor 14 is also included, penetrating the bottom cover 12 and electrically connected to the electronic components covered by the top cover 11 and the bottom cover 12. Thus, the water immersion sensor can accurately acquire the downhole liquid level in real time, solving the problem that existing monitoring equipment cannot provide accurate liquid level information and is inadequate in applications requiring detailed liquid level data. This greatly expands the effectiveness, reliability, and applicability of the monitoring terminal's data collection.

[0030] In conclusion, the monitoring terminal provided by the utility model has the advantages that the top cover and the bottom cover are made of corrosion-resistant cast aluminum material, so that good corrosion resistance is achieved, the outer surfaces of the top cover and the bottom cover are subjected to paint baking treatment, so that the waterproof performance of the top cover and the bottom cover is further improved, the internal cavity formed by the top cover and the bottom cover can be completely isolated from the external environment, so that the entire monitoring terminal can continuously work normally in a water immersion state; at least one second antenna interface is arranged on the bottom cover, so that different mounting positions are provided for the connection of the antenna, so that the monitoring terminal can conveniently install the antenna, so that the installation flexibility of the entire monitoring terminal is improved under the premise of ensuring the communication capability of the monitoring terminal; the water immersion sensor can accurately acquire the liquid level height in real time, so that the problem that the existing monitoring equipment cannot provide accurate liquid level height information is solved, the effectiveness, reliability and applicability of data collection of the monitoring terminal are greatly improved in application occasions where detailed liquid level data is required.
