Rope is wrapped on reel, and steel wire rope free end passes through line outlet, and end is arranged pull head, shell and bottom plate and passes through sealing first
Circle sealing, spring case and shell are sealed by sealing element, and signal transmission device and bottom plate are sealed by second seal, the sealing
Sealing ring can be used in part, and signal wire is connect with signal transmission device by seal nipple；The bottom plate is provided with seal groove, the shell
Sealed step corresponding with seal groove is arranged in body, and the height of sealed step is less than the depth of seal groove, and sealing ring is placed in seal groove.
Further to improve, the seal groove shaped main body is circular ring shape and is arranged along bottom edge.
Further to improve, the spring of the spring case uses plane scroll spring.
Further to improve, spring case is fixed with casing bolts, and shell is fixed with bed bolt, bottom plate and signal transmission device
Bolt is fixed.
Further to improve, reel is set on the exposed transmission axle of signal transmission device and is fixed by fixing bolt.
The utility model provides a kind of underwater sensor, has following the utility model has the advantages that being passed through by shell and bottom plate
Sealing ring sealing, spring case and shell are sealed by first seal, and signal transmission device and bottom plate are sealed by second seal,
Signal wire is connect with signal transmission device by seal nipple, and bottom plate is provided with seal groove, and the shell setting is corresponding with seal groove
Sealed step, the height of sealed step is less than the depth of seal groove, and sealing ring is placed in seal groove, prevents water entering signal from transmitting
Device makes the utility model adapt to shallow water underwater working environment, adapts within underwater 5 meters of depths.

Specific embodiment
As shown, a kind of use sensor, including shell 1, bottom plate 2, spring case 3, signal transmission device 4, spring case under water
3, shell 1, bottom plate 2, signal transmission device 4 are successively mutually fixed, and reel 5 is arranged in shell 1, and the fixation of reel 5 is set in signal
On the exposed transmission axle of transmitter 4,4 outer surface of signal transmission device is coated with sealant, and reel 5 is set in signal transmission device 4
It is fixed on exposed transmission bearing and by fixing bolt；, the spring in spring case 3 uses plane scroll spring 31；Shell 1 is arranged
Line outlet 11, wirerope 6 are wrapped on reel 5, and 6 free end of wirerope passes through line outlet 11, and pull head 61, shell is arranged in end
Body 1 is sealed with bottom plate 2 by sealing ring 71, and spring case 3 is sealed with shell 1 by first seal 72, signal transmission device 4 and bottom
Plate is sealed by second seal 73, and signal wire 75 is connect with signal transmission device by seal nipple 74；Spring case 3 and shell 1
Bolt is fixed, and shell 1 is fixed with 2 bolt of bottom plate, and bottom plate 2 is fixed with 4 bolt of signal transmission device.
The bottom plate 2 is provided with seal groove 81, and 81 shaped main body of seal groove is circular ring shape and sets along 2 edge of bottom plate
It sets, sealed step 82 corresponding with seal groove 81 is arranged in the shell 1, and the height of sealed step 82 is less than the depth of seal groove 81
Degree, sealing ring 71 are placed in seal groove 81.
Wirerope one end is fixed on pull head, the other end pass through line outlet be fixed on reel, wirerope-winding around
In line wheel, for pull head 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 the further signal transmission device of rotation of reel, reel one end and plane scroll
Spring connection, the other end are connected by fixing screws with signal transmission device, and device signal is sent by signal wire across seal nipple
Out.Pull head pulls the variation of the mobile generation of wirerope that can be converted into signal and transfers out.After pull head moves a certain distance, lead to
The power that plane scroll spring acts on reel is crossed, initial position is returned to.Thus complete the process of a measurement displacement.
