Abstract
The utility model provides a balanced scuba of inside and outside pressure. The utility model relates to a scuba technique specifically is a technique and device of utilizing inside atmospheric pressure to resist outside water pressure. The utility model provides a scuba, take inside and outside balanceing of pressure and offset the squeezing action that the scuba shell received, help reducing the design and manufacture cost of scuba shell. The technical scheme main points that adopt are: the outside water pressure and inside atmospheric pressure of scuba are measured through the pressure comparator, if outside water pressure is greater than inside atmospheric pressure, it increases the inside gas of scuba then to open air filler valve to improve the inside atmospheric pressure of scuba, if outside water pressure is lighter than inside atmospheric pressure, then through the inside gas of drain tap release scuba to reduce the inside atmospheric pressure of scuba.

Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, submersible has shell 100.With shell 100 for border, being that submersible is outside beyond this shell, is that submersible is inner within this shell; Shell 100 is sealings, under the state of non-breakage, the Leakage Gas of submersible inside can either be stoped outside to submersible, the water permeation of submersible outside also can be stoped inner to submersible.
Submersible is provided with gas cylinder 300, charging valve 400 and drain tap 500.Gas cylinder 300 storage has high pressure gas, and gas cylinder 300 is connected with the gas access of charging valve 400, and the gas vent of charging valve 400 is then communicated in the space of submersible inside.The gas access of drain tap 500 is communicated in the space of submersible inside, and the gas vent of drain tap 500 is then communicated in the space of submersible outside.
Submersible is provided with pressure comparator 200.This pressure comparator can measure the pressure difference of submersible outside and submersible inside; If the hydraulic pressure of submersible outside is powerful in the gas pressure intensity of submersible inside, and exceeded set threshold value, then output a control signal to drain tap 500 and make it to close, output a control signal to charging valve 400 and make it to open, thus it is inner to improve the gas pressure intensity of submersible inside the high pressure gas in gas cylinder to be filled with submersible; If the hydraulic pressure of submersible outside is less than by force the gas pressure intensity of submersible inside, and exceeded set threshold value, then output a control signal to drain tap 500 and make it to open, output a control signal to charging valve 400 and make it to close, thus the gas of submersible inside externally being discharged the gas pressure intensity reducing submersible inside; If the pressure difference of submersible external water pressure by force and between submersible internal gas pressure does not exceed set threshold value, then by closing charging valve and drain tap, the air pressure of submersible inside is remained unchanged.
Like this, along with the increase of submersible submerged depth, submersible external water pressure is by corresponding increasing; Pressure comparator controls the on off state of drain tap and charging valve, and air pressure rises by inflating gas cylinder to make submersible inner space; The air pressure risen offsets the outside hydraulic pressure increased to the squeezing action of shell.Otherwise when submersible is in propradation, pressure comparator also can correspondingly control drain tap and charging valve, makes the air release of submersible inner space and reduces air pressure.By this balance dynamically maintaining pressure inside and outside submersible, the shell of submersible just can be avoided to cause breakage due to the reason of hydraulic pressure, shell also just can be made not need special bearing capacity, thus reduce the design and manufacture cost of shell.
Above-described embodiment, the one of the detailed description of the invention of just carrying out according to the technical solution of the utility model; The usual property change carried out within the scope of technical solutions of the utility model and replacement all should be included in protection domain of the present utility model.
