Description
Technical field
The invention belongs to the marine technology field, relate to a kind of underwater miniature conduction draw ring, is a kind of submerged cable conduction draw ring, can on an extra large cable, be connected in series a plurality of these draw rings.
Background technology
Real time implementation, networking, informationization are progressively moved towards in current oceanographic observation and monitoring.Adopted from holding subsurface buoy storage sensor image data reclaims the subsurface buoy obtaining information again to appointed place by boats and ships mode in the past and can not meet growing national marine cause.And real time implementation, informationalized prerequisite are in real time a large amount of reliable and stable transmission of data, this transmission means is easy on land realize, but particularly becomes extremely difficult under water marine.The depth of water is darker, and hydraulic pressure is larger, and every dark 10 meters increase an atmospheric pressure, and the corrosion strength of seawater, biological attachment etc. all cause great impact to underwater instrument equipment.
Thereby the employings such as current oceanographic survey, marine monitoring and observation, far-reaching extra large scientific investigation is still self-tolerant storage, regularly recovery; Perhaps subsurface buoy is combined with buoy, and data are by the mode of acoustics MODEM transmission.For a long time, sensing data under water and observation signal are all from capacitance type, to be stored in instrument, because if by cable or in fill out Kevlar fiber cable connect water surface float, in generally fracture in two weeks to 3 month of cable under ocean current and tidal action, the consequence that causes data to transmit.The little speed of signal bandwidth is low by underwater sound communication, to transmit data, and electroacoustic low conversion rate and serious interference etc. cause the mass data can't real-time Transmission.
Underwater conductive sliding ring of the prior art, by outside framework oil seal and the sealing of O circle, to completely cut off seawater on the basis of electric slip ring, this mode can play a role in several meters scopes under water, but the increase along with the depth of water, O circle and outside framework oil seal can produce great enclasping force to the seal shaft place, finally cause slip ring to rotate.The rotation that secondly current all underwater conductive sliding rings do not support to bear certain pulling force (tens kg are to hundreds of kg).And submerged cable transmission data must be born certain pulling force, pulling force is often at least more than 100kg, and some even needs the pulling force of ton.So current underwater conductive sliding ring is only applicable to shallow water without the application in the pulling force situation, there is no actual application prospect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of underwater miniature conduction draw ring, avoid in ocean cable to be subject to action of ocean current when long-term transmission data and twisted off.Adopt the present invention can effectively solve the problem that pulling force torsion that extra large cable causes in ocean current trend and underwater installation motion can't discharge voluntarily, under the prerequisite that guarantees data communication, the torsion that cable is subject to can make draw ring freely rotate, discharge the torsion in hawser, and then can ensure the transmission of the long time stability of data.Torsion in water discharges very easily by cable in the present invention, does not affect the transfer of data of the signal of telecommunication simultaneously.Application the present invention real-time Data Transmission under water can not need more than 1 year to safeguard for a long time.Its technical scheme is as follows:
A kind of underwater miniature conduction draw ring, comprise housing, described housing upper end connecting stator fixed body and conduction stator, the conduction stator is fixed on stator fixed body middle part by hold-down nut, the wire of stator is connected with watertight connector and is fixed on stator fixed body upper end, upper draw ring and connector are fixed on stator fixed body upper end by screw thread, the middle part of described housing is provided with radial thrust bearing, lower radial thrust bearing, upper radial thrust bearing, lower radial thrust bearing is coordinated with rotation axis by adjusting nut and stop washer, electric rotors is fastened on the rotation axis lower end by multicore cable and weather proof receptacle, lower draw ring and lower connector are fixed on the rotation axis lower end by screw thread, the bottom of housing is provided with the pressure balance seal device, the inside of housing is provided with pouring orifice and exhaust outlet, housing top is by O type circle static seal.
Further preferably, described housing is a cylinder, adopts 316L stainless steel or titanium alloy material.
Further preferably, described pressure balance seal device is three layers.
Compared with prior art, beneficial effect of the present invention:
1. the present invention adopts the high accuracy radial thrust bearing, can play drawing-resistant function, is characterized in rotating flexibly, and resistance is little.
2. the present invention adopts the pressure balance seal device, its effect: can effectively stop seawater to enter enclosure interior, can when rotating, guarantee the balance of housing external and internal pressure again.
3. technical solution of the present invention adopts weather proof receptacle to make the use of this draw ring more safe and reliable and convenient, and use procedure can separately be fixed pulling force and power cables.
4. of the present invention compact to design small and exquisite, the resistance be subject under hydrodynamic environment and the net buoyancy that need to additionally provide are little, are convenient to on-the-spot the installation and construction, require low, widely applicable to extra large cable.
The accompanying drawing explanation
Fig. 1 is the structural representation of underwater miniature conduction draw ring of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate technical scheme of the present invention.
With reference to Fig. 1, a kind of underwater miniature conduction draw ring, comprise housing 6, and described housing 6 is a cylinder, adopts 316L stainless steel or titanium alloy material.Described housing 6 upper end connecting stator fixed bodies 5 and conduction stator 7, conduction stator 7 is fixed on stator fixed body 5 middle parts by hold-down nut 8, the wire of stator is connected with watertight connector 3 and is fixed on stator fixed body 5 upper ends, upper draw ring 1 is fixed on stator fixed body 5 upper ends with connector 2 by screw thread, can play the effect of connection cable and wire.
The middle part of described housing 6 is provided with radial thrust bearing 13, lower radial thrust bearing 14, upper radial thrust bearing 13, lower radial thrust bearing 14 are coordinated with rotation axis 16 by adjusting nut 11 and stop washer 12, free to rotate when bearing external broach 100kg-1000kg, electric rotors 10 is fastened on rotation axis 16 lower ends by multicore cable 15 and weather proof receptacle 19, lower draw ring 21 is fixed on rotation axis 16 lower ends with lower connector 20 by screw thread, can play the effect of connection cable and wire.
