Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0020] Such as Figure 6 , Figure 7 As shown, the liquid-sealed electronic direct-reading water meter includes a counting mechanism with a dial, a photoelectric module and a liquid-sealed character wheel box, and an impeller metering mechanism with upper and lower clamping plates.

[0021] The impeller metering mechanism includes the impeller 3, the impeller box 2, the gear train 7, the gear box 4, the upper splint 10, and the lower splint 5. The upper end of the impeller shaft is installed on the lower splint 5, so that the space of the water meter can be fully and rationally used, see Figure 6 , There is a filter screen 1 under the impeller box 2.

[0022] Such as figure 2 , Figure 6 , Figure 7 As shown, the counting mechanism includes a photoelectric module 11, a character wheel box 12, a dial 13, a pointer 14, a watch glass 15, a four-eight cone set 9,...

Abstract

A liquid sealed electronic direct reading water meter comprises a dial, a photovoltaic module, a counting mechanism of a liquid sealed character wheel box, and an impeller measuring mechanism with upper and lower splints; the photovoltaic module is arranged above the liquid sealed character wheel box and separated from the character wheel by a partition board with interval grooves on both sides; a photovoltaic panel of the photovoltaic module at the upper part and the character wheel at the lower part are respectively positioned at both sides of the partition board and are corresponding to each other; and the corresponding positions on the photovoltaic module corresponding to the figures on the character wheel are provided with openings or are transparent. The liquid sealed electronic direct reading water meter has the advantages of effectively protecting the photovoltaic module and overcoming the disadvantage that the original structure needs to use special glue layer to seal the photovoltaic module, under the premise of ensuring a clear reading; besides, the production of the water meter is simpler, so that the production efficiency can be improved and the production cost is reduced; at the same time, the lead wire of the photovoltaic module can be directly and easily educed out, and has lower sealing requirements. Only a simple sealing at the lead wire position can easily and rapidly solve the sealing problem of the entire photovoltaic module space.

Description

Technical field [0001] The invention relates to a water meter, in particular to a water meter capable of transmitting data remotely. Background technique [0002] The liquid-sealed electronic direct-reading water meter is a water meter that can read directly and remotely. It generally includes a counting mechanism and an impeller measuring mechanism. The counting mechanism includes a fully liquid-sealed water meter word wheel box and a photoelectric module. A character wheel is arranged in the wheel box, a photoelectric module is arranged in the electronic module box, a mark is arranged on the edge of the character wheel, and a photoelectric sensor is arranged on the photoelectric module. The photoelectric sensor senses the mark signal on the character wheel and passes the signal through The transmission line is output to the outside. The electronic module box is placed under the character wheel box. The character wheel window is open. The dial and the character wheel are immerse...
