Abstract

The utility model discloses a gate level meter with a large range. The utility model is composed of a measuring tube, a circuit board, a magnetic ring and dry reed tubes; the magnetic ring is sheathed on the measuring tube, the magnetic ring is fixedly and directly connected with a lock gate, and the dry reed tubes are uniformly distributed on the measuring tube; the circuit board is a resistance voltage divider which is in multi-stage serial connection and is composed of equivalent resistors which are connected in series, and each contact point is connected with one dry reed tube. When the lock gate is opened, the dry reed tubes is made by the magnetic ring which is sheathed on the measuring tube under the action of magnetic force of the magnetic ring to switch on a switch, a circuit obtains a voltage division value which is converted by the circuit, and thus the displacement of the lock gate can be read. Therefore, the utility model has the characteristics of simple circuit and exact measurement.

Description

A kind of wide range gate level meter

The utility model relates to a kind of wide range gate level meter.

At present, traditional gate level meter is to drive a scrambler or potentiometer with a rotating disk, measures with one of wire rope and is fixed on the gate upper end; The other end hangs a weight, the pulling steel wire drives and rotates when gate moves up and down, the code-disc of servo-actuated has write down the displacement of gate, this structure have action component easy to wear, skid, influence the life-span, to the environmental requirement height, scrambler is output as set of pulses amount complicated circuit such as need decode, transmission range is limited, can produce error code and cumulative errors in measurement, when range is big, error is big.

The purpose of this utility model is to provide a kind of non-cpntact measurement, full waterproof, attonity parts, circuit is simple, accuracy of measurement is high wide range gate level meter.

For achieving the above object, wide range gate level meter of the present utility model is made up of measuring tube, wiring board, magnet ring, tongue tube, and measuring tube is fixed on the gate slot, and magnet ring is set on the measuring tube, between magnet ring and the gate for fixedlying connected; Tongue tube is evenly distributed on the measuring tube; Wiring board is the resitstance voltage divider of a plural serial stage, and voltage divider is in series with substitutional resistance, and connects a tongue tube on each contact.

After adopting such structure, owing to be to fixedly connected between the collar and the gate, when gate is opened, magnet ring moves on measuring tube, tongue tube in the measuring tube is subjected to magneticaction and connects, and obtains the partial pressure value on this tongue tube from circuit, thus the displacement of accurately reading this gate.

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is a scheme of installation of the present utility model,

Fig. 3 is circuit theory diagrams of the present utility model.

Be made up of measuring tube 1, wiring board 2, magnet ring 3, tongue tube 4 as Fig. 1, Fig. 2, wide range gate level meter of the present utility model shown in Figure 3, measuring tube 1 is fixed on the gate slot 6, and magnet ring 3 is set on the measuring tube 1, between magnet ring 3 and the gate 7 for fixedlying connected; Tongue tube 4 is evenly distributed on the measuring tube 1; Wiring board 2 is resitstance voltage dividers of a plural serial stage, and voltage divider is in series with substitutional resistance 5, and connects a tongue tube 4 on each contact; The gap that tongue tube 4 on the measuring tube 1 is write between the tongue tube 4 is 10 millimeters.During measurement, when gate 7 opens to certain position, magnet ring 3 just is parked in a certain position on the measuring tube 1, tongue tube 4 in magnet ring 3 these positions is subjected to magneticaction to connect switch, makes to obtain a certain partial pressure value on the circuit board, by the conversion of circuit, thereby read the displacement of gate 7, make wide range gate level meter of the present utility model have circuit simple, measure accurately, be a kind of non-cpntact measurement, and full waterproof gate level meter.
