Description

Sealed variable box for water meter

Technical Field

The utility model belongs to the technical field of the water gauge manufacturing technology and specifically relates to indicate a sealed variable case for water gauge.

Background

The water meter is an instrument for measuring water flow, and the traditional water meter drives the pointer to rotate by the rotation of the impeller through the impact of water flow on the impeller blade in the water meter, so that the effect of measuring the water flow is achieved. The intelligent valve-controlled water meter is a new-type water meter which utilizes modern microelectronic technique and modern sensing technique to measure water consumption and make water consumption data transmission and settlement transaction. When the user uses water, the water quantity acquisition device starts to acquire the water quantity and converts the water quantity into a required electronic signal to be supplied to the microcomputer module for metering. The motor and the transmission gear set of the existing intelligent valve-controlled water meter are both designed in a sealing box, only one layer of sealing is provided, once the water leaks and is affected with damp, the motor is easy to be short-circuited and burnt out, and the valve-controlled water meter is caused to lose efficacy, which is often caused in the environment with much rainwater in the south.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a sealed variable case for water gauge makes the motor be in a relatively independent space through the three-layer seal, can effectively avoid the motor because of the condition that wets arouses the short circuit or burn out. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

A sealed variable box for a water meter comprises a sealed box, wherein the sealed box comprises a sealed bottom cover and a sealed top cover, a first transmission gear set is arranged in the sealing bottom cover, the first transmission gear set is connected with a sector gear, the sector gear is provided with a shaft hole, the sector gear is sleeved on the valve rod through the shaft hole, switch buttons are arranged on two sides of the sector gear, a second sealing box is arranged above the sealing bottom cover and comprises a lower bottom plate, a sealing ring and an upper cover plate, the lower bottom plate is provided with a second transmission gear set which is connected with the first transmission gear set through a transmission gear shaft, the upper cover plate is provided with a motor fixing seat and a sealing ring, the motor fixing seat is provided with a motor, the end of the motor shaft is connected with a second transmission gear set, a motor accommodating cavity is formed in the sealing top cover, and the motor accommodating cavity is tightly matched with the sealing ring.

Furthermore, a plurality of hollow support columns are arranged below the lower bottom plate, and the hollow support columns are sleeved on a shaft of the transmission gear set.

(III) advantageous effects

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a three-layer seal makes the motor be in a relatively independent space, can effectively avoid the motor to arouse the condition of short circuit or burning out because of weing.
