Abstract
A current meter with a signal generator consists of an airscrew, a meter body, the signal generator and an empennage. The meter body is a support of a main body, the front end of the meter body is provided with the airscrew, and the mid position of the meter body is provided with a locating support hole; the front of the locating support hole is provided with a hollow barrel cover of the signal generator. In the direction that the aircrew meets the current, the current impacts the aircrew to rotate, and the aircrew drives a rotation axis to rotate, the number of revolution of the rotation axle is transmitted to the signal generator through a transmission device in the meter body. The empennage is positioned at the end of the meter body to ensure the aircrew to keep meeting the current, under the impact of the current. The adoption of the utility model simplifies the sampling of current. Moreover, behind the aircrew, the signal generator arranged in the shell of the meter body emits radio signal, which avoids the trouble caused by a connecting line, ensures the sampling of the signal to be more reliable and increases the speed of the sampling of the signal greatly.
Description
Technical field: the utility model relates to the water conservancy project instrument, relates in particular to a kind of current meter that contains signal generator.
Background technology: the cup-type current meter of prior art and propeller current meter, all be that flow velocity with current is converted into revolution, be sent to the signal generator that is arranged on the fish lead with wired form again, be sent to receiving device by signal generator with wired or wireless form again, get the flow velocity of water outlet as calculated.Be arranged on signal generator and bad fixing on the fish lead, be easy to come off; Add signal generator on the fish lead and can increase the volume of the equipment entry of testing the speed, increase resistance to water-flow, pasture and water easy to hang; The transmission line interface is many, easy break-down; Especially the current meter flow measurement speed of prior art is slow, can not satisfy the needs of the anti-danger of flood fighting.
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of current meter that contains signal generator is provided, signal generator is assembled in the rear portion of screw propeller with the form of integrated circuit, in the housing of current meter instrument body, the flow velocity signal of current is sent on the bank receiving device with the form of wireless transmission.
Summary of the invention: a kind of current meter that contains signal generator described in the utility model, including screw propeller, instrument body, signal generator and empennage forms, said instrument body is a kind of body supports part that contains the current meter of signal generator described in the utility model, said screw propeller is arranged on the front end of instrument body, the centre position of instrument body is provided with the positioning supports hole, can the instrument body be arranged on the support member with the form of lower support, the also form that can support with hanging oneself, penetrate in the supported hole with support pin, hang liter with steel cable, below again with fish lead counterweight and location.On one's body the instrument of front, positioning supports hole, be provided with the round barrel shape signal generator housing of hollow.Meet direction with screw propeller to current, the rotation of water impact screw propeller, the rotation of propeller-driven turning axle, the revolution of turning axle is delivered to signal generator by the gearing in the instrument body.Said signal generator is arranged in the signal generator housing at instrument body middle part, the rotation of water impact screw propeller, and per 1 circle, 5 circles, 10 circles or 20 circles are a switch unit.Said empennage is arranged on the end of instrument body, under the impact of current, guarantees that screw propeller is in the state of the stream that meets water all the time.Said signal generator, radio signal generator that is sealed in the instrument body central enclosure just matches with on the bank radio signal receiving apparatus.Enclose as a revolution signal that switch unit sent by per 1 circle, 5 circles, 10 circles or 20 by signal generator, receive and computing, be easy to just can obtain the flow velocity and the flow of water through receiving trap.Can be in the use according to streamflow regime, the switch unit of setting signal generator.
Use a kind of current meter technology that contains signal generator described in the utility model, on existing fish lead, no longer mount signal generation apparatus, reduced the impulsive force of current, made the sampling work simplification of current to fish lead.And in the back of screw propeller, signalization generator in the housing of instrument body adopts the radio signal emission, has avoided the puzzlement of connecting line, makes that the sampling work of signal is more reliable, and the sample rate of signal also can be greatly improved.
