Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and not restrictive, and that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like, as used herein, refer to orientations or positional relationships based on those illustrated in the drawings, and are used merely to facilitate describing the invention and to simplify the description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not intended to be limiting. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in the figure, for the deep sea diving suit life support system, a pneumatic hydraulic control panel 1 is provided, and oxygen is transmitted from a main oxygen bottle 21 to a main pressure regulator 4 through a pressure switch and an oxygen supply switch 39 which are positioned in the pneumatic hydraulic control panel by using a conduit through a main oxygen stop valve 23 and a main oxygen regulating valve 24, so that the pressure inside the diving suit is regulated, and the normal operation of each system loop is ensured. The oxygen delivered from the main oxygen cylinder 21 is delivered to the injector 11 by a conduit and then delivered to a hose in the helmet by the injector for supplying oxygen.
The emergency oxygen control valve 38 is also a part of the pneumatic hydraulic control panel 1, when the emergency oxygen control valve is opened, a part of the oxygen delivered from the emergency oxygen cylinder 10 directly enters the hose with the air outlet in the helmet through the conduit, and the other part of the oxygen enters the injector 11 through the conduit and is delivered into the helmet by the injector to complete oxygen supply. When the emergency oxygen cylinder is lack of oxygen, the self-generating oxygen part is triggered to operate, and at the moment, water in the small soft water tank 45 flows into the oxygen making tank 44 with the oxidant through the stop valve beside the soft water tank, so that oxygen is generated and supplied through the same loop of the emergency oxygen.
The emergency oxygen control valve 38 and the pressure switch and oxygen supply switch 39 may be activated simultaneously to increase the oxygen flow. In addition, the emergency oxygen control valve is automatically activated when the pressure inside the diving suit is below a critical value of 20 kPa. The emergency oxygen control valve is used for controlling the on-off of the emergency oxygen loop, the emergency oxygen stop valve controls the on-off of the emergency oxygen supplement when the emergency oxygen is supplemented, when the emergency oxygen loop runs, the emergency oxygen stop valve is automatically controlled to be opened through a program after the emergency oxygen control valve is opened, and when the emergency oxygen control valve is disconnected, the emergency oxygen stop valve is simultaneously disconnected.
The main oxygen part can be recharged through a main oxygen connector 25, the pressure sensor 22 can monitor the actual pressure data of the oxygen cylinder, the data can be displayed on a display, the downstream of the oxygen cylinder is controlled to be switched on and off by an oxygen stop valve 23, and an oxygen regulating valve downstream of the oxygen stop valve is used for introducing oxygen. The emergency oxygen section also performs the same operations as the main oxygen section to accomplish oxygenation. In addition, the raw material replacement in the small soft water tank 45 and the oxygen production tank 44 with the oxide can be performed in the autogenous oxygen generation part through the connector.
When the pressure switch and oxygen supply switch 39 are activated, the ventilation line is activated and the air is passed through the fan module 40 via the ventilation line to the contaminated air treatment tank 20 where the carbon dioxide and odors from the air are absorbed as gaseous waste. The treated gas is treated by the heat treatment device 15 to change moisture in the gas into water condensate, and the water condensate is separated by the moisture separator 14 and is input into the heat treatment device 15 to be used as a cooling liquid. The gas passing through the moisture separator contains a part of oxygen to be fed again into the ejector 11. This extends the length of oxygen usage. The oxygen ventilation pipeline and the ventilation pipeline are connected with the ejector 11, so that on one hand, oxygen in the ventilation pipeline can be reused; on the other hand, when a problem occurs with the ventilation line fan module 40, the ejector 11 may be used as a backup ventilation power device. At this time, the oxygen supply system supplies oxygen into the ejector at a large flow rate, and discharges the oxygen through the relevant control device. The exhaust gases can carry away carbon dioxide and harmful gases, as well as heat and remove moisture.
When the water supply control valve 32 is opened, the water in the soft water tank 8 is introduced into the thermal processor 15 through the water supply adjusting valve 18 and the water supply filter 16 by the pressure inside the wetsuit, ensuring the normal operation of the thermal processor 15.
When the temperature control valve 31 is opened, the condensed water in the heat processor 15 is transported to the condensation clothes 7 through the condensed water processor 43 with the bubble separator and the main and auxiliary pump 42, then a part of the condensed water is directly returned to the condensed water processor 43 with the bubble separator through the temperature control valve, and a part of the condensed water is returned to the heat processor 15 through the condensed water meter 19, thereby realizing the circulation of the condensation cooling loop. In the process of the condensation cooling loop, the condensed water can take away heat generated in the body through the whole body, so as to ensure the temperature in the diving suit. At the same time, the ambient heat and the equipment heat are also removed by entering the heat treatment device 15 through the condensation cooling loop.
The main oxygen bottle pressure sensor is mainly used for detecting pressure data in the main oxygen bottle in real time, and the data can be displayed on a display screen.
The main pressure regulator (4) and the auxiliary pressure regulator (5) are mainly used for regulating the pressure in the diving suit so as to ensure the normal operation of each system and loop.
The ventilation gas flow sensor (6) is arranged at a hose between the deep sea diving suit helmets and controls the gas circulation rate.
The fan module (40) is comprised of two fans, each fan being driven by a sealed motor, the second fan being automatically activated when the first fan is deactivated. In special cases, two fans may be used simultaneously to increase the gas flow.
The polluted gas treatment tank (20) is used for treating the gas in the ventilation pipeline. The polluted gas treatment tank (20) mainly comprises three main parts: lithium hydroxide absorbs carbon dioxide, activated carbon absorbs odors and other gaseous waste, and a particulate filter absorbs particles to prevent lithium hydroxide dust from entering the ventilation duct.
The condensed water processor (43) with the bubble separator is mainly used for processing the condensed water flowing out of the heat processor (15), and the bubble separation in the condensed water is carried out by utilizing the centrifugal principle, so that the operation efficiency of the condensation cooling loop is improved.
The main pump and the auxiliary pump (42) are mainly used for improving the separation of condensed water, and the main pump and the auxiliary pump are connected in series, so that when the main pump is blocked by bubbles, the water pump can not work normally, and the auxiliary pump can replace the main pump to work continuously.
The heat treatment device (15) mainly comprises a heat exchanger and a heat sublimator. The heat exchanger is mainly used for condensing part of water provided by the water supply loop to generate condensed water with adjustable temperature. The heat sublimator is mainly used for treating water vapor condensate generated after moisture in a ventilation pipeline is condensed by the heat processor (15), treating the water vapor condensate by the moisture separator (14), and then conveying the treated water vapor condensate to the heat processor (15) for reutilization.
Furthermore, about 1.2kg of available gaseous oxygen is stored in the main oxygen bottle, the storage pressure is 30MPa, the contained oxygen can supply oxygen for about one hour at the flow rate of 1.5/h, and supply oxygen for about one and a half hours at the flow rate of 1.1/h. The main oxygen part is connected with the main oxygen loop through a connector. The main oxygen loop can generate three branches after being connected through a main oxygen pipeline: one part of the pressure is directly passed through the check valve (28) and the flow limiting valve (17) and the main and auxiliary pressure regulators (5) to enter the main and auxiliary pressure regulators (5) so as to regulate the pressure in the garment; another part will enter the injector (11) through the one-way valve (28) through the main oxygen circuit regulating valve and the one-way valve (28) finally through the oxygen ventilation pipe; the last part will pass the non-return valve (28) and directly enter the injector (11). The injector (11) is used for delivering the input oxygen into the helmet through a hose with an air outlet positioned in the helmet to provide the oxygen required by the staff.
Further, the emergency oxygen loop comprises an emergency oxygen portion and a self-generated oxygen portion. The emergency oxygen comprises an oxygen cylinder and an oxygen component which are the same as the main oxygen part, and the oxygen content of the emergency oxygen is supplied for at least about 30 minutes under the flow rate of 2/h, so that the sufficient oxygen supply of personnel in emergency is ensured. In addition, when the emergency oxygen part is about to be exhausted, the self-generating oxygen part can be automatically started, a certain amount of oxygen is generated by the self-generating oxygen part through the reaction of water and oxide, and the oxygen amount can be maintained to be 1.5/h and supplied for about 15 minutes. A part of the emergency oxygen loop is directly conveyed into the helmet through the emergency oxygen pipeline, and a part of the emergency oxygen loop enters the ejector (11) through the one-way valve (28) and the like and is finally conveyed into the helmet so as to complete oxygen supply for workers.
