Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the description of the specific embodiments is intended for purposes of illustration only and is not intended to limit the scope of the present disclosure.

As shown in FIG. 1, the wireless remote water meter comprises a base meter 1, an electronic module 2, a base meter cover 3 and a clamping structure.

As shown in fig. 5, the electronic module includes a module case 4, a main board 5, a sensor 6, a battery 7, and a protective cover 12. As shown in fig. 9, the module box is internally provided with an upper bin 4-1 and a lower bin 4-2 which are arranged up and down, the upper bin and the lower bin are separated by a partition board 4.1, a through hole 4.2 is arranged on the partition board, and a sealing plug (omitted in the drawing) seals the through hole. The main board, the sensor and the protective cover are arranged in the upper bin, the battery is arranged in the lower bin, and the battery is electrically connected with the main board through a wire (omitted in the figure) penetrating through the sealing plug. As shown in fig. 9, the upper bin is further provided with a side bin 4-3 protruding sideways, which side bin extends above the base surface cover. The sensor is arranged in the side bin, and the sensor is encapsulated in the side bin through pouring sealant.

The main board is encapsulated in the upper bin through pouring sealant. The upper bin is also provided with a protective cover, the protective cover is positioned above the main board and the sensor, the protective cover is fixed in the upper bin through the matching of the positioning groove 4.3 and the positioning block 12.4, the positioning groove is arranged on the inner wall of the upper bin, and the positioning block is arranged on the side face of the protective cover. The protective cover is also encapsulated in the upper bin through pouring sealant, and the pouring sealant and the protective cover form double-layer protection, so that the sealing performance of the main board and the sensor is ensured.
