Description
Technical field
The invention belongs to underwater power device field, for the equipment of underwater operation provides the power supply of safety and stability, assurance equipment normally moves.
Background technology
Along with being surging forward of Undersea Scientific Expedition and Underwater resources development activities, underwater installation is also more and more advanced, and most underwater installation all needs the supply of power supply, and underwater power source becomes the key component of the normal work of assurance equipment.Existing under-water DC power supply architecture is complicated and expensive.Many times, directly select battery pack good seal, battery pack is placed in sealing cabin, select the circuit of waterproof.General sealing cabin is formed by rubber, plastics, fiber or metal material manufacture.Due to the intensification of under-water DC power supply along with working water level, the hydraulic pressure that sealing cabin periphery is subject to also increases thereupon, and sealing cabin is carried out to crimp, even damaged, thereby causes the danger of electric leakage, and personal safety as well as the property safety is produced and threatened.Existing under-water DC power supply exists the defect that does not tolerate hydraulic pressure.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, a kind of under-water DC power supply is provided, it tolerates hydraulic pressure, and cost performance is high, for underwater installation provides, continues sufficient stable electric current.
The technical scheme that realizes the object of the invention is: the DC power supply of this underwater operation, and comprise sealing cabin and be placed on the dc-battery group in sealing cabin, in sealing cabin, be filled with filling liquid.
Wherein, the filling liquid in sealing cabin body is transformer oil.
Preferably, in sealing cabin outside, scribble radiating and cooling coating.
Preferably, inside and outside sealing cabin, be equipped with radiating fin.
Preferably, radiating fin is processed as cylindrical or strip.
Preferably, on radiating fin, be processed with small through hole.
The present invention compares with existing under-water DC power supply, the invention has the beneficial effects as follows:
Because the sealing cabin inside dc-battery group is housed is filled with filling liquid, thereby water pressure resistance more.At deep water place, sealing cabin still can keep internal and external pressure balance, the not yielding breakage of protection sealing cabin.
Further, because filling liquid is chosen as transformer oil, transformer oil has the effect of radiating insulating, avoids dc-battery group to make moist and corroded in air.
Further, owing to being equipped with radiating fin inside and outside the top cover labyrinth of capsul and cylinder top, when being placed in the power supply operation of capsul inside, produce heat, hot-fluid rises, radiating fin absorbs after heat, and with the form of convection current, by dissipation of heat, thereby under-water DC power supply heat sinking performance of the present invention is good.
Further, owing to being processed with small through hole on radiating fin, increase the surface area of radiating fin, thereby accelerated heat radiation.
Further, owing to scribbling radiating and cooling coating in sealing cabin outside, thereby under-water DC power source integral of the present invention heat radiation evenly.
Further, due to dc-battery group mainly by alkaline battery, diode and fuse string and connect and compose, at every batteries parallel diode, at every Battery pack series diode, positive pole in battery pack is connected in series fuse, thereby effectively prevents the appearance of inverse current impulse and short circuit phenomenon.
Test shows, this invention can be the DC power supply that underwater installation provides safety and stability, guarantees that it normally moves.
