Abstract
The utility model discloses a be applied to lock gate's aperture appearance, including installing on gate hydraulic cylinder laser object distance sensor, installing laser target plate, treater and display on the gate piston rod, laser object distance sensor with the central point of laser target plate is on same straight line, laser object distance sensor with the treater is connected, the treater with the display is connected. The utility model has the advantages that adopting the laser object distance to measure and replacing mechanical transmission mechanism to measure, the structure is more simple, easy to maintain, and the cost only be former half, laser object distance measuring range is long, the precision is high, and does not receive external environment's interference, and stability is high, and life also has and improves by a wide margin.
Description
Technical field
This utility model belongs to gate control field, and in particular to a kind of aperture instrument.
Background technology
Lock gate is opened standard in place and is reacted with aperture, measures typically using opening self-detective instrument.Gatage
Instrument is divided into principle：The automatic take-up formula of spring, the automatic take-up formula of gravity, direct displacement measurement formula and coaxially connected formula.
The existing opening self-detective instrument of ship lock, generally using spring automatic take-up (steel wire rope) formula, which is mainly by two parts group
Into a part is encoder section, and a part is spring case part.During measurement, measuring cable is wrapped on spring case axle, while using
Shaft coupling is coupled with encoder, makes encoder and measured axis synchronous axial system, by the rotation that the translating rotation of measured axis is encoder axle
Turn, survey cable and move with gate and pull out, retracted by spring force, the change for surveying cable reflects the open degree of gate, encoder output
Corresponding gatage numerical value.
This mechanical aperture instrument, because surveying cable length limitation, aperture instrument range is inadequate；Because spring life is limited, spring
Mechanism is easily aging；Cable (steel wire rope) easily winding, abrasion are surveyed, cable is surveyed affected by environment larger.Spring case maintenance is big, maintenance cost
Height, and ship lock high frequency time switch gate is not suitable with, spring case, lining rope service life are short.
Therefore need a kind of simple structure, it is easy to safeguard, the high aperture instrument of certainty of measurement.
Utility model content
Utility model purpose：For the problems referred to above, it is long that the purpose of this utility model is to provide a kind of range, stability it is high and
Aperture instrument easy to maintain.
Technical scheme：A kind of aperture instrument for being applied to lock gate, including installed in laser object distance on gate hydraulic jack
Sensor, the laser target plate on gate piston rod, processor and display, the laser object distance sensor with it is described
Laser target plate is centrally located on same straight line, and the laser object distance sensor is connected with the processor, the processor with
The display connection.
Cable connection can be adopted between laser object distance sensor and processor, it would however also be possible to employ the mode of communication connects.
Processor adopts PLC processor.
Beneficial effect：Compared with prior art, the utility model has the advantages that replacing machinery to pass using the measurement of laser object distance
Motivation structure is measured, and structure is more simple, it is easy to safeguard, and cost is only former half；The range length of laser object distance measurement, essence
Degree is high, and is not disturbed by external environment, and stability is high, and service life is also greatly improved.
Description of the drawings
Fig. 1 is this utility model structural representation (adopts between laser object distance sensor and PLC processor and electrically connect)；
Fig. 2 is this utility model structural representation (using communication connection between laser object distance sensor and PLC processor).
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, further elucidate this utility model, it should be understood that these embodiments are only used for
Illustrate this utility model rather than limit scope of the present utility model, after this utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.
A kind of as shown in drawings, aperture instrument for being applied to lock gate, including laser object distance sensor 1, laser target plate 2,
PLC processor 3 and display 4.Laser object distance sensor 1 is arranged on the hydraulic jack 5 of gate, and laser target plate 2 is arranged on
On the piston rod 6 of gate, both keep center on the same line.With the change of displacement between the two, corresponding position is produced
Move value signal.
Can be by cable connection, to transmit a signal to PLC process between laser object distance sensor 1 and PLC processor 3
Device process；As shown in Figure 2, it is also possible to connect the forms such as transmission signal, such as wifi, bluetooth by way of communication, to realize nothing
Line communicates, remotely control.PLC processor 3 is connected with display 4, the displacement value signal after process is shown over the display, i.e.,
For opening value.
Principle of the present utility model is：The generally keying of gate, is entering using the power of motor by actuating device
Capable.Theoretically, (motor-oil pump-hydraulic jack-gate or motor-deceleration on the whole link from motor to gate
Machine-worm gear-endless screw-gate) any one moving component, can reflect the change of the open degree of gate.Select hydraulic jack
Laser object distance device is installed with piston rod, is conducive to installation, and do not affect the position of shutter motion, be optimum selection.
During gate opening/closing, the piston rod 6 in hydraulic jack 5 promotes gate, and its motion makes laser target plate 2 pass with laser object distance
The distance between sensor 1 produces change.Laser sensor 1 exports gate displacement value signal in real time, is transferred to PLC processor 3 and enters
Row is processed, then the aperture of gate is drawn by conversion, is shown on display 4.
This utility model, mechanical transmission, structure are more simple, convenient for installation and maintenance, and are difficult by extraneous ring
The interference in border, reliable and stable, measurement distance, precision are greatly improved, and the efficiency of navigation has been effectively ensured.
