Description

A hydrological terminal device

technical field

The utility model relates to the technical field of data acquisition equipment, in particular to a hydrological terminal device.

Background technique

Similar products currently on the market mainly use non-sealed structures, or box-type structures that are fastened with screws. The non-sealed structure is not conducive to moisture-proof and dust-proof, and the screw-fastened box-type structure is not conducive to manual opening operation. In view of the above problems, we have specially introduced a hydrological terminal device, which solves the problem of moisture and dust resistance through a sealed structure; it is convenient for manual opening operation by rotating the upper cover.

Utility model content

In view of the above problems, the utility model aims to provide a hydrological terminal device.

In order to achieve this technical purpose, the solution of this utility model is: a hydrological terminal device, including a circuit board, an upper cover base, an upper cover cap, a lower shell, a mounting piece, a GSM antenna connector, a copper column, a GSM antenna, 7 Core aviation plug, 8-core aviation plug, 10-core aviation plug, the base of the upper cover is provided with a round hole, the round hole is provided with an internal thread, the upper cap is provided with an external thread, and the upper cap is screwed on the circle through the thread. In the hole, the base of the upper cover is fixedly connected to the lower case by screws, and the bottom of the lower case is fixedly connected to the mounting plate by screws, and the circuit board and copper pillars are respectively installed inside the lower case, wherein the circuit board is fixed on the copper pillars by screws, The GSM antenna connector is connected to the side of the lower shell, the top of the GSM antenna connector is connected to the GSM antenna, and the GSM antenna connector is respectively equipped with a 7-pin aviation plug, an 8-pin aviation plug and a 10-pin aviation plug.

Preferably, sealing strips are installed at the connection between the base of the upper cover and the upper cap, and the connection between the base of the upper cover and the lower shell, and all joints are led out through waterproof aviation plugs to prevent moisture and dust.

The hydrological terminal device of the utility model is moisture-proof and can work in a humidity environment of 95% RH; and the opening time is within 10 seconds, which has obvious advantages and certain practical value.
