Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the application, and the terms "upper," "lower," "inner," "outer," "top/bottom," etc. indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate describing the invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the invention. 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 life support system of the deep sea diving suit of the present invention, a pneumatic hydraulic control panel 1 is provided, and oxygen is delivered from a main oxygen bottle 21 to a main pressure regulator 4 through a main oxygen stop valve 23 and a main oxygen regulating valve 24 by using a conduit through a pressure switch and an oxygen supply switch 39 located therein, so as to regulate the pressure inside the diving suit and ensure the normal operation of each system loop. Oxygen supplied through the main oxygen cylinder 21 is supplied to the injector 11 by a conduit and supplied by the injector to a hose in the helmet for oxygen supply.
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 oxygen conveyed from the emergency oxygen bottle 10 directly enters a hose with an air outlet in the helmet through a conduit, and the other part of oxygen enters the injector 11 through the conduit and is conveyed into the helmet by the injector to complete oxygen supply. When the oxygen in the emergency oxygen bottle is insufficient, the operation of the self-generating oxygen part is triggered, and at this time, water in the small soft water tank 45 flows into the oxygen generating tank 44 with the oxidant through the stop valve beside the soft water tank, so that oxygen is generated, and oxygen is 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 wetsuit is below the threshold value of 20 kPa. The emergency oxygen control valve is used for controlling the opening and closing of the emergency oxygen loop, the emergency oxygen stop valve is used for controlling the on-off of the emergency oxygen supplement when the emergency oxygen is supplemented, when the emergency oxygen loop is operated, the opening of the emergency oxygen stop valve is automatically controlled through a program after the emergency oxygen control valve is opened, and when the emergency oxygen control valve is opened, the emergency oxygen stop valve is simultaneously opened.
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 bottle, the data can be displayed on a display, the on-off of the oxygen bottle is controlled by an oxygen stop valve 23 at the downstream of the oxygen bottle, and oxygen is introduced by an oxygen regulating valve at the downstream of the oxygen stop valve. The emergency oxygen section also performs the same as the main oxygen section to complete oxygenation. In addition, the raw material in the small soft water tank 45 and the oxygen generating tank 44 with oxide can be replaced by a connector in the self-oxygen generating portion.
When the pressure switch and the oxygen supply switch 39 are activated, the ventilation line is activated, and the gas is passed through the fan module 40 via the ventilation line to the contaminated gas treatment tank 20, after which the carbon dioxide and the bad smell in the gas are absorbed as gaseous waste. The treated gas is treated by the heat processor 15 to change moisture in the gas into hydraulic gas, and then is separated by the moisture separator 14 and is input into the heat processor 15 to be used as cooling liquid. The oxygen in the gas-containing portion passing through the moisture separator is fed again into the ejector 11. This prolongs the duration of use of oxygen. The oxygen ventilation pipe and the ventilation pipe are connected with the ejector 11, so that on one hand, the oxygen in the ventilation pipe can be reused; on the other hand, when a problem occurs in the ventilation line fan module 40, the ejector 11 may be used as a spare ventilation power device. In this case, the oxygen supply system supplies oxygen into the injector at a large flow rate, and the oxygen is discharged through the associated control device. The vented gases can carry away carbon dioxide and hazardous gases, as well as carry away heat and remove moisture.
When the water supply control valve 32 is opened, water in the soft water tank 8 passes through the water supply regulating valve 18 and the water supply filter 16 to enter the heat processor 15 under the pressure effect in the diving suit, so that the normal operation of the heat processor 15 is ensured.
When the temperature control valve 31 is opened, condensed water from the heat processor 15 is transported into the condensation suit 7 through the condensed water processor 43 with the bubble separator and the main pump 42, and then part of the condensed water is directly returned into the condensed water processor 43 with the bubble separator through the temperature control valve, and part of the condensed water is returned into the heat processor 15 through the condensed water meter 19, so that the circulation of the condensed cooling loop is realized. In the condensation cooling loop process, the condensed water can take away heat generated in the body through the whole body, so that the temperature in the diving suit is ensured. At the same time, the ambient heat and the equipment heat also enter the heat processor 15 for removal 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 each loop.
The ventilation gas flow sensor (6) is arranged at a hose between the helmets of the deep sea diving suit and used for controlling the gas circulation rate.
The fan module (40) is composed of two fans, each fan is driven by a sealed motor, and when the first fan is not active, the second fan is automatically started. 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 of component devices: the lithium hydroxide absorbs carbon dioxide, activated carbon absorbs odors and other gaseous waste, and the particle 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 condensed water flowing out of the heat processor (15), and the centrifugal principle is utilized for separating bubbles in the condensed water, so that the operation efficiency of the condensation cooling loop is improved.
The main pump (42) is mainly used for improving 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 auxiliary pump can replace the main pump to continue to work when the water pump cannot work normally.
The heat processor (15) mainly comprises a heat exchanger and a component device of the 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 mainly processes the moisture in the ventilating duct, condenses by the heat processor (15), and then produces vapor condensate which is processed by the moisture separator (14) and then is conveyed to the heat processor (15) for reuse.
Further, about 1.2kg of available gaseous oxygen is stored in the main oxygen bottle, the storage pressure is 30MPa, and the oxygen contained in the main oxygen bottle can be supplied with oxygen at a flow rate of 1.5/h for about one hour and at a flow rate of 1.1/h for about one half hour. The main oxygen portion is connected to the main oxygen circuit by a connector. The main oxygen loop is connected through a main oxygen pipeline to generate three branches: a part of the pressure can directly pass through the one-way 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; the other part of the oxygen enters the injector (11) through the check valve (28) through the main oxygen loop regulating valve and the check valve (28) finally through the oxygen ventilation pipeline; the last part passes through the one-way valve (28) and then directly enters the ejector (11). The injector (11) conveys the input oxygen into the helmet through a hose with an air outlet positioned in the helmet, and provides oxygen required by staff.
Further, the emergency oxygen circuit includes an emergency oxygen portion and a self-generating oxygen portion. The emergency oxygen comprises an oxygen bottle and an oxygen assembly which are the same as the main oxygen part, and the oxygen content of the emergency oxygen is supplied for at least 30 minutes at the flow of 2/h, so that the oxygen supply is sufficient under the emergency condition of personnel. In addition, when the emergency oxygen part is about to be exhausted, the self-generating oxygen part can be automatically started, and certain oxygen is generated by the self-generating oxygen part through the reaction of water and oxide, and the oxygen amount can be maintained to supply oxygen for about 15 minutes at the flow rate of 1.5/h. The emergency oxygen loop is partially directly conveyed into the helmet through the emergency oxygen pipeline, and partially enters the ejector (11) through the one-way valve (28) and the like and finally is conveyed into the helmet so as to complete oxygen supply for staff.
Furthermore, a proper amount of condensate is stored in the heat processor (15), and flows through the whole body through the condensate processor with the bubble separator and the main pump (42) and the auxiliary pump through the condensation clothes (7) and the condensation pipeline, so that heat exchange is carried out to take away superfluous heat of the body, and the human body feels comfortable. The condensed water circulates in the condensed water loop so as to keep the effect of continuous cooling.
Further, the ventilation circuit is driven by a fan to cause air to flow over the body surface to carry away perspiration and heat. When the gas passes through the polluted gas treatment tank (20) during the circulation in the loop, the waste gas can be cleaned, and the carbon dioxide content can be controlled, so as to achieve the aim of pollution control. In addition, after the moisture in the ventilation pipeline passes through the heat processor (15) and the moisture separator (14), the collected moisture is conveyed to the heat processor (15) for use.
Further, a group of carbon dioxide sensors are arranged between the oxygen ventilation pipeline and the ventilation pipeline, so that the concentration of carbon dioxide in the garment can be detected in real time and displayed on a display screen.
The main oxygen loop, the ventilation loop, the water supply loop, the condensation cooling loop and the emergency oxygen loop not only meet the oxygen supply, ventilation, heat preservation and cooling required by the life support system of the diving suit, but also are provided with some emergency measures to ensure the life health of a user through a standby scheme when a certain loop has a problem.
The life support system not only designs a main oxygen loop but also designs an emergency oxygen loop to ensure the oxygen supply safety of a user. When the main oxygen loop is in a problem, the emergency oxygen loop is adopted for supplying oxygen, and the self-generating oxygen part is designed, so that the oxygen supply time is greatly prolonged on one hand, and on the other hand, when the emergency oxygen part is in a problem, the self-generating oxygen part can be used for supplying oxygen. And three guarantees are provided in the aspect of oxygen supply, so that the oxygen supply safety coefficient of a user is greatly improved.
The ejector (11) designed by the life support system is connected with a main oxygen loop, an emergency oxygen loop and a ventilation loop. Thus, the pressure in the garment can be maintained at reduced pressure, and the carbon dioxide is maintained at an allowable level by purging the garment with pure oxygen when a problem occurs in the contaminated gas treatment tank (20). When the fan module (40) has a problem, a large flow of oxygen can be supplied to the ejector (11), and the ejector kinetic energy generated when the ejector (11) is supplied with a large amount of oxygen is utilized to drive the gas in the ventilation loop to flow. And further can take away carbon dioxide and harmful gases in the gas, and take away heat and a small amount of moisture.
Residual gas in the oxygen supply circuit can be vented by opening the vent valve 34 when the wetsuit is not in use. While the invention has been described with respect to certain preferred embodiments, it will be apparent to those skilled in the art that various changes and substitutions can be made herein without departing from the scope of the invention as defined by the appended claims.
