Description
Technical field
The present invention relates to underwater cable protection device, more particularly to a kind of underwater mechanism for installing of sensor.
Background technology
Underwater cable is that ocean underwater optical cable, cable and various ocean underwater installations and marine dragging system etc. provide water
The services such as lower communication, electric power and pulling force.The reliability of underwater cable is directly determined under ocean underwater optical cable, cable, ocean water
The security and validity of equipment, marine dragging system and anchoring system.Cable in use, due to stress in seawater
（Underwater Pressure, hydro-flow thrust, different kind organism and object touch）Complexity, operating mode are severe, it is easy to which the bending for producing cable is beaten
Knot, fatigue wear, it is therefore desirable to the information such as working condition and shape to underwater cable is monitored in real time, relatively more at present
Way is in its surface mount foil gauge or multi-axial sensor etc.（Foil gauge or multi-axial sensor are referred to as cable state below
Detection sensor）, the information transfer for then being detected cable state detection sensor by communication module is to computer, then leads to
Cross digital simulation and go out the information such as cable real-time geometric.Existing cable state detection sensor is easily produced in actual use
Raw situations such as intaking, damage by pressure, damaging.
The content of the invention

Monitoring driving mechanism 6 includes sound generating mechanism 61, control unit 62, first pressure sensor 63, second pressure sensing
Device 64 and the flexible layer 65 being wrapped in outside shell.The surface distributed of flexible layer 65 has triggering pin 67.Shape between flexible layer 65 and shell 7
Into cavity 66.The full hydraulic oil of filling in cavity 66.First pressure sensor 63 is arranged in cavity 66.Second pressure sensor 64
It is arranged in shell 7.Sound generating mechanism 61 and control unit 62 are all disposed within shell.First pressure sensor 63, second pressure
Sensor 64 and sound generating mechanism 61 are electrically connected to same control unit 62.
Referring to Fig. 2, sound generating mechanism 61 includes drive mechanism 611, whistle 612 and what is set gradually first determine stripper plate
613rd, the first air bag 614, dynamic stripper plate 615, the second air bag 616 and second determine stripper plate 617.Drive mechanism 611 includes being oriented to
Bar 6111, screw mandrel 6112 and motor 6113.Guide rod 6111 determines stripper plate 613 and second along first and determines stripper plate 617
Distribution arrangement extends.One end of guide rod 6111 determine that stripper plate 613 is fixed together, the other end second determines stripper plate together with first
617 are fixed on and cut.Guide rod 6111 is located on dynamic stripper plate 615.Screw mandrel 6112 is parallel with guide rod 6111.Screw mandrel 6112
One end be rotatably connected on by bearing first determine on stripper plate 613, the other end is rotatably connected on second by bearing and determines stripper plate
Linked together on 617 and with the power output shaft of motor 6113.Screw mandrel 6112 is threaded on dynamic stripper plate 615.
Motor 6113 is stepper motor.First air bag 614, which is fixed on first, to be determined on stripper plate 613.First air bag 614 is provided with first
Enter outlet nozzle 6141.First enters outlet nozzle 6141 is sealed connected together with the entrance point of whistle 612.Second air bag 616 is the same as the

Referring to Fig. 1 and Fig. 2, in use, underwater cable passes through shell through threading opening 74, threading opening seals with cable main body 1
Link together.Cable state detection sensor is installed to the part that underwater cable is located in shell, Ran Hou through pouring orifice 71
The oil that refuels is indicated in shell, is oiled lid 711 in closure.
As the pressure of interior intracavitary with the pressure in shell is when normal, the pressure that first pressure sensor detects subtracts
To remove the difference A obtained by the pressure that second sensor detects be zero therefore the preset value B of timed unit is 0 when designing, therefore A-B=
0, control unit does not start the sounding of sound generating mechanism 61.When have external force extruding avoid fish bait and hit or the impact of current or
When extruding of the weight of shell 7 etc. causes the pressure rising in inner chamber 66, now A-B ＞ 0, control unit make the sounding of sound generating mechanism 61
And fish are expelled.If A-B is more than 0 for continuous more than one minute, expression causes the increased power source of chamber pressure to be to lead to
Cross that sound drives away is also that non-animal such as fish is signified, then carries out sounding and drive do not have effect then, and now control unit 62 makes
Sound generating mechanism 61 stops sounding and is revised as preset value B to stop what sound generating mechanism sounding moment first pressure sensor detected
Pressure subtracts the difference A obtained by the pressure that second sensor detects.If the pressure that modification more than can produce interior intracavitary improves
For preset value B can be more than the phenomenon of difference A instantaneous value caused by the impact of burst, then after external force disappearance, the phenomenon
Produced in the presence of the phenomenon that is unable to be found when can cause to have fish to damage shell 7, thus this control unit further just like
Lower functional module, i.e., if it find that the pressure that first pressure sensor detects is subtracted obtained by the pressure that second sensor detects
Difference A when being less than preset value B, preset value B is adjusted to detect equal to the moment first pressure sensor by control unit 62
Pressure subtract difference A obtained by the pressure that second sensor detects.
The process of the sounding of sound generating mechanism 61 is during control unit：Motor 6113 is made forward and reverse reciprocating motion, drive
The rotating of 6113 drive screw of motor 6112, the driving of screw mandrel 6,112 615 left reciprocating motion of dynamic stripper plate, dynamic stripper plate 615 extrude
First air bag 614 and the second air bag 616 so that air-flow flows by whistle 612 between the first air bag and the second air bag, air-flow
By causing whistle sounding to produce sound during whistle 612.
The setting for triggering pin 67 causes the effect of isolation fish.
