Description
Technical field
The present invention is specifically related to a kind of new type ultrasonic water meter.
Background technology
Current bigbore ultrasonic water meter instead of the widespread use that mechanical water meter obtains people, but the function of existing ultrasonic water meter is more single, the needs of people can not be met, such as, people usually with during water without controlled, waste water resource, and existing ultrasonic water meter does not have water amount alarm function, people's water consumption can not be reminded in time.The display screen of existing ultrasonic water meter is monochromatic LED display screen, and expressive ability is limited, can not show measured value intuitively, and if rather dark, do not see the numerical value on display screen, can to checking that the staff of water meter makes troubles.
In addition, because the size of ultrasonic transducer is comparatively large, and the diameter of the intake-outlet of small diameter watermeter is less, and the application of small diameter watermeter is restricted, and ultrasonic type small diameter watermeter exists very large error on the minimum flow velocity of measurement.
Summary of the invention
The object of the invention is to overcome the problem that ultrasonic water meter function in prior art is more single and use small diameter watermeter to be restricted.
For this reason, the invention provides a kind of new type ultrasonic water meter, comprise watch shell and LCDs, watch shell is provided with water inlet and water delivering orifice, it is characterized in that: described LCDs is chromatic liquid crystal screen, spherical expansion chamber first and spherical expansion chamber second is provided with in described watch shell, the bottom of spherical expansion chamber first and spherical expansion chamber second is respectively equipped with ultrasonic reflections column first and ultrasonic reflections column second, described ultrasonic reflections column first and ultrasonic reflections column second top are respectively equipped with a catoptron first and catoptron second, the top that each catoptron is corresponding is provided with ultrasonic transducer, single-chip microcomputer is provided with in described watch shell, single-chip microcomputer respectively with ultrasonic transducer, the hummer be embedded in watch shell connects, single-chip microcomputer is connected with chromatic liquid crystal screen by the chromatic liquid crystal screen driving circuit be arranged in housing, the surrounding of described chromatic liquid crystal screen is provided with LED.
Described LED has four, is embedded in the chromatic liquid crystal screen left and right sides respectively between two, and four LED parallel connections are connected with the internal battery of ultrasonic water meter by being arranged on the switch on the upside of LCDs afterwards.
The angle of the minute surface of reflecting optics that described ultrasound wave column first and ultrasound wave column second top are arranged respectively and the axis of ultrasonic reflections column is 45 °, and two reflecting optics in opposite directions.
One end of described watch shell water inlet is provided with by-pass valve control, and described by-pass valve control is connected with valve numerical-control motor, and described valve numerical-control motor is connected with single-chip microcomputer.
Described spherical expansion chamber first and the diameter of spherical expansion chamber second are 1.6 times of water inlet or water delivering orifice diameter.
Beneficial effect of the present invention: compared with prior art, the present invention has set up water amount alarm function, can remind people's water consumption in time, avoid waste water resource.In addition, have employed chromatic liquid crystal screen, make the display of measured value more directly perceived, around colorful display screen, be provided with LED, for checking that the staff of water meter provides conveniently under rather dark.By arranging spherical expansion chamber, the mode of built-in ultrasonic transducer and ultrasonic reflections column makes small diameter watermeter be applied, and reduces the turbulent flow impact near ultrasonic reflections column, reduce the generation of eddy current, improve the stability of measurement with accurate, structure is simple, and cost is lower.
Below with reference to accompanying drawing, the present invention is described in further details.
