Abstract
The utility model provides a stay wire displacement sensor for underwater use. In a stainless steel housing, a cable wire (4) in a wire angle converter passes through the stainless steel housing (1) and is horizontally wound on a reel (2). A shaft extension end of the reel is connected with a reaction spring (3) which controls a telescoping tension of the cable wire, and the other end is provided with a magnet (5). An angle sensor (7) is fixed on an insulation plate (11) through a bracket (10). A rotation shaft of the angle sensor is provided with a magnet (8). The rotation shaft and the magnet are packed in a stainless steel combined housing (6), and the stainless steel combined housing is connected with a wire angle converter housing (1). A waterproof cable (9) for outputting an electric signal by the sealed angle sensor is introduced out. A wire outlet is fixed by a sealing chuck (12). Therefore linear displacement through pulling the cable wire is realized for causing a magnetic shaft of the reel to simultaneously rotate for reeling the wire. Through magnetic force coupling, the magnetic shaft of the angle is pulled for rotating simultaneously. The linear displacement of the cable wire is converted to an angle sensor signal and is output from the cable conductor. The electrical measurement for the linear displacement is realized through calibration.
Description
1. technical field
The utility model relates to a kind of backguy displacement transducer of using under water, especially can be operated in the backguy displacement transducer of 100 meters of the depth of waters.
2. background technology
Present known backguy displacement transducer, its principle are straight-line displacement to be converted to angle measure, and line angle converter and measuring angular transducer that it is used by spiral are formed, and connect by shaft joint between the two.Hole on the backguy steel wire penetrating sensor housing is connected spiral with the reel in the housing, and the spiral angle is measured by angular transducer, and spiral length is represented the backguy elongation, can obtain by reel diameter and spiral angle calculation.The measurement of angle sensor generally adopts multiturn potentiometer or rotary encoder, but, these electron device water proofing properties are poor, the backguy displacement transducer is in water the time, outside water can enter in the angular transducer by through wires hole, cause electric fault, therefore, this backguy displacement transducer can not use in water.
3. utility model content
In order to overcome the shortcoming that angular transducer can not use in the existing backguy displacement transducer in water, the utility model at first adopts all-sealed structure to angular transducer, makes it have water-proof function, can use in water.Simultaneously, shaft joint connected mode that need not be traditional, and adopt magnetic couplings connecting shaft mode to connect line angle converter and angular transducer, realize the two is carried out seal isolation.
The utility model solves its technical scheme: the parts that the backguy displacement transducer are separated into line angle converter and 2 seal isolation of measurement of angle device, the line angle converter is made up of wire rope, reel, bearing, magnet and reaction spring, is encapsulated in the Stainless Steel housing.The measurement of angle device is made up of angular transducer, support, magnet, signal cable and is sealed in another Stainless Steel housing.Backguy steel wire penetrating line angle converter Stainless Steel housing, flat on reel, reel rotation spiral angle and backguy elongation have exact linear relation.The reel of line angle converter is that twin shaft is stretched, and an end of axle is equipped with a magnet, other end dress reaction spring.The measurement of angle device is by angular transducer, support, and magnet, signal cable are formed, and are sealed in another Stainless Steel Shell.Another magnet is housed in the angular transducer rotating shaft, and the angular transducer output voltage signal connects with water-proof cable draws outside the housing, and cable outlet is fixed on the measurement of angle device housing with sealed cartridge.Because the measurement of angle device seals, when placing water, electronic unit such as angular transducer and water are isolated fully, have guaranteed the sensor reliably working.
By a terminal pad butt joint of line angle converter and measurement of angle device is integral, makes magnet on the two turning axle on same axis, form magnetic force coupling connecting shaft mechanism.During the flexible generation of backguy wire rope displacement, line angle converter rotation spiral is by magnet suction on the axle, the rotating shaft of pulling angular transducer is rotated synchronously, the line angle converter anglec of rotation, promptly the backguy telescopic displacement is converted to the angular transducer anglec of rotation and carries out electric measurement.Can calculate the backguy displacement according to the flexible long linear relationship of backguy with measurement of angle voltage.
The beneficial effects of the utility model are, this backguy displacement transducer can be measured under water, and the mounting points degree of depth can reach 100 meters.
4. description of drawings
Below in conjunction with accompanying drawing the utility model embodiment is further specified:
Among Fig. 1: 1. line angle converter shell, 2. reel, 3. reaction spring, 4. wire rope backguy, 5. magnet, 6. measurement of angle device housing, 7. angular transducer, 8. magnet, 9. cable, 10. angular transducer support, 11. terminal pads, 12. welding connectors, 13. bearings.
5. embodiment
In Fig. 1, Stainless Steel silk rope (4) passes Stainless Steel housing (1) and puts down on reel (2), and reel is that twin shaft is stretched, and supports rotation by two bearings (13), and the end that twin shaft is stretched is connected with reaction spring (3),
The other end is equipped with magnet (5), and above construction packages is formed the line angle converter in Stainless Steel housing (1).Angular transducer (7) is installed in earlier on the support (10), and then be fixed on the terminal pad (11), magnet (8) is installed on the angular transducer turning axle, cable (9) outlet of angular transducer output signal, wire hole is fixing with welding connector (12), and above sealing structure is formed the measurement of angle device in Stainless Steel housing (6).By terminal pad (11). line angle converter shell (1) and measurement of angle device housing (6) are connected into one use the backguy displacement transducer under water
Thereby realize: the flexible generation of backguy wire rope displacement, make reel rotation spiral, magnet rotates simultaneously on the spiral wheel shaft, close by the magnetic force lotus root that magnet rotates synchronously on the pulling angular transducer axle, angular transducer is converted to the angle voltage signal with the wire rope straight-line displacement and exports from cable, because angle voltage signal and backguy telescopic displacement have exact linear relation, through calibrated and calculated, can obtain backguy wire rope telescopic displacement value.
