Description
Technical field
The present invention relates to the subaqueous survey instrument, specifically a kind of rotatable watertight contactor.
Background technology
In ocean expedition, in river, river, lake, the pool hydrologic survey, need obtain the related parameter that has of the hydrology by the observation of the subaqueous survey instrument of multiple function.Under many circumstances, measuring instrument must hang in the water or on seat and other carrier and use, owing to flowed to the influence that variation or carrier move, measuring instrument usually will be with flow to changing or carrier moves and rotates, influenced by it, the cable of connection instrument is owing to the rotation of instrument produces wrapping phenomena, and this cable winding problem that causes owing to the instrument rotation will directly influence the certainty of measurement of instrument, and weight person causes cable breakage that instrument can't be worked.
The subaqueous survey instrument rotates under water and causes that the winding of cable never has good solution; The similar device that can see (generally claiming slip ring) major part is used in the road on the ground at present, partly mostly adopts the contact seal mode of sealing ring or sealing ring with underwater similar device, and frictional force is big, and the subaqueous survey instrument of inapplicable rotation uses.
Summary of the invention
It is unimpeded but also prevent to produce the rotatable watertight contactor that cable twines because the subaqueous survey instrument rotates to the purpose of this invention is to provide a kind of power supply of not only having guaranteed the subaqueous survey instrument and measuring-signal.
For addressing the above problem, the technical solution used in the present invention is:
The present invention has following advantage:
1. not having cable winding problem produces.When upper cable was rotated with measuring instrument, subjacent cable did not rotate when the present invention used.
2. fail safe is good.The present invention is a kind of device that the subaqueous survey instrument is connected with cable that is used for; Utilize the siphonage principle, thereby critical component brush and electricity ring are in the protection of transformer oil body all the time.
3. certainty of measurement height.The present invention adopts the contactless rotation water-stop under rotary state, thereby makes the rotation of device more flexible, and frictional force is littler, has improved the certainty of measurement of rotating measuring instrument under water greatly
4. use depth of water scope big.Earlier be full of oil body in device before the present invention uses, thereby accomplish that oil body and the outer water body of device in the device is in inside and outside equipressure all the time in the course of work under water, in principle, this device can be operated in any depth of water.
5. raising service behaviour.The present invention is for both guaranteeing measuring instrument operate as normal under water, can guarantee that again instrument freely rotates, reliable in order to guarantee brush with contacting of electricity ring, the present invention can adopt the way of contact of double brush, four contacts, and on the material therefor of brush and electricity ring, carry out optimized choice, thereby can improve the contact reliability of contact greatly, the service behaviour of contactor is improved.
