Description
Technical field
The present invention relates to a kind of lock level monitoring system, and in particular to a kind of lock level monitoring system based on grating measuring.
Background technology
Gate level meter is the common detecting instrument of water conservancy industry, and what is mainly applied at present is cable formula, is moved by the switch of flashboard
Make the folding and unfolding of drive hawser, so as to drive rotary encoder to rotate, obtain lock position data.Such gate level meter installation is complicated, wheel
Son, which skids, causes data inaccurate, and hawser can be made to wave so as to influence the detection of lock position when external wind is big.Along with the row of gate
Cheng great, the accuracy of detection of lock position is inadequate, result in lock position bigger error.The accuracy of gate level meter have impact on the nurse to water resource
The wastage of ability and water resource.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of precision height, the prison of the lock position based on grating measuring being easily installed
Examining system.
In order to solve the above technical problems, the technical scheme is that：A kind of lock level monitoring system based on grating measuring,
Its innovative point is：Including screw mandrel, mounting bracket, nut, grating scale and display instrument；The screw mandrel is horizontally set on deceleration
On case output shaft and it is located at reduction gearbox output shaft end；The mounting bracket is by horizon bar A, vertical bar B and horizon bar C groups
Into；End face is connected with horizon bar A right-hand members at the top of the vertical bar B, and its bottom end face is connected with horizon bar C left ends；The grating
Chi is fixedly connected on horizon bar A and be arranged in parallel with leading screw；The horizon bar C is fixedly connected on reduction box casing；It is described
Nut is arranged on screw mandrel.
Further, the grating scale specification is 50 lines/1mm, the specification of 50 lines/1mm grating scale resolution ratio.
Further, also there is A/D modular converters between the grating scale and display instrument.
The advantage of the invention is that：
（1）The big stroke of flashboard is converted into the small-range that leading screw tightens up a screw, is easy to detect；In view of use environment and peace
Holding position, lock level monitoring system is arranged on by gearbox, equipment is concentrated and is easy to safeguard；
（2）It is small using high-precision grating scale error；
（3）For grating scale by A/D modular converters, the signal for exporting 4-20mA shows detection to display instrument, is also other
System reserves standard interface.
Brief description of the drawings
Fig. 1 is a kind of lock level monitoring system overall schematic based on grating measuring of the present invention.
Fig. 2 is a kind of lock level monitoring system detail view based on grating measuring of the present invention.
Embodiment
As shown in figure 1, the invention discloses a kind of lock level monitoring system based on grating measuring, including screw mandrel 14, installation
Support 13, nut 15, grating scale 11 and display instrument 12；Screw mandrel 14, which is horizontally set on the output shaft of reduction box 2 and is located at, to be subtracted
Fast case 2 exports shaft end, is rotated with output shaft synchronous；Mounting bracket 13 is made up of horizon bar A, vertical bar B and horizon bar C；
End face is connected with horizon bar A right-hand members at the top of vertical bar B, and its bottom end face is connected with horizon bar C left ends；Grating scale 11 is fixedly connected
It is be arranged in parallel on horizon bar A and with leading screw 14；Horizon bar C is fixedly connected on the housing of reduction box 2；Nut 15 is arranged on screw mandrel
On 14, the revolute pair of screw mandrel 14 is changed into the prismatic pair that nut 15 moves linearly；The reductor of general control gate 3 is exported from lock
The standard-sized sheet of door 3 turns left the right side to fully closed about 200, intends 300 turns, the height 10m of gate 3 calculating, the pitch 0.5-1MM of leading screw 14, nut 15
Mobile position probably brings great convenience in 15-30cm, this length to the use of grating scale 11；The specification of grating scale 11
For 50 lines/1mm, 50 lines/1mm grating scales are the specification of resolution ratio, and precision can reach 0.02mm, for lock position can be accurate
To 0.33cm；Also there is A/D modular converters, grating scale 11 passes through A/D moduluss of conversion between the grating scale 11 and display instrument 12
Block, the signal for exporting 4-20mA detect to display instrument 12, moreover it is possible to provide standard signal to equipment such as PLC, LCU.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
