Specific embodiment
A kind of position sensor, including pull ring 16, line outlet 17, wirerope 18, reel 5, inner spring box 3, outer spring
Box 2, shell 4, bottom plate 6, transmission shaft 7, signal transmission device 11；It further include connecting plate 9, shield 10, water-stop socket 12, watertight
Seal cable 13, the first drive assembly 14, the second drive assembly 15, seal cavity 8；8 side of seal cavity is fixedly connected with
Connecting plate 9, the other side are fixedly connected with bottom plate 6；Shield 10 is fixedly connected on the connecting plate 9, signal transmission device 11 is solid
Fixed to be arranged in shield 10 and connect through connecting plate 9 with the first drive assembly 14,11 other end of signal transmission device runs through water
Seal socket 12 is connect with Water-tight seal electric cable 13, and 6 other side of bottom plate is fixedly connected with shell 4, reel 5 and transmission shaft 7
It is fixed；One end that wirerope 18 is fixed on reel 5 is wrapped in wirerope 18 on reel 5, and 18 other end of wirerope passes through
Line outlet 17 is fixedly connected with pull ring 16, and 7 one end of transmission shaft is connect with plane scroll spring 1, the other end and the second drive assembly
15 connections, transmission shaft 7 are connect by bearing with bottom plate 6 and shell 4 respectively.
Preferably, inner spring box 3 is fixed on shell 4 by screw, and outer spring box 2 is fixed on inner spring box 3 by screw
Outer wall, 2 part shell wall of outer spring box are socketed on inner spring box 3.
Preferably, the sealing ring of water-stop socket 12 is elastic material, and inner core is glass capsulation.
Preferably, first drive assembly 14 and the second drive assembly 15 are magnet assembly, can make second in this way
15 side of drive assembly is completely enclosed, and water inlet when preventing work ensure that the reliably working of sensor.
Preferably, 13 inner core of Water-tight seal electric cable uses glass capsulation
Wirerope one end is fixed on pull ring, the other end pass through line outlet be fixed on reel, wirerope-winding around
In line wheel, for pull ring by pulling the wirerope on reel to generate movement, reel pulls the steel for being wrapped in it by pull ring
The movement of cord and generate rotation, the rotation of reel drives the rotation of transmission shaft by fixed screw, transmission shaft one end with
Plane scroll spring connection, the other end are connected by shaft coupling with signal transmission device, and device signal is passed through explosion-proof by signal wire
Connector is sent out.It is transferred out so pull ring pulls the variation of the mobile generation of wirerope that can be converted into signal.Pull ring mobile one
After set a distance, the power of reel is acted on by plane scroll spring, is returned to initial position.Thus complete a measurement position
The process of shifting.
