Description

Technical Field

[0001] The present invention relates to the technical field of underwater lifesaving equipment, and in particular to an air temperature and humidity regulating system for an underwater lifesaving cabin that actively changes a ventilation structure and a regulating method thereof. Background Art

[0002] In the vast field of deep-sea operations and emergency rescue, underwater lifeboats play a vital role. They are not only a shelter for the lives of people in distress, but also a key equipment to ensure their safety while waiting for rescue. The stability of the air temperature and humidity inside them is directly related to the survival safety of the occupants.

[0003] Most traditional underwater lifeboats use a fixed ventilation structure, supplemented by an air-conditioning system to regulate the temperature and humidity inside the cabin. These structures have many defects, such as: the conventional single-duct design results in a limited contact area with the cabin wall, making it impossible to quickly reduce the temperature and humidity inside the cabin in a high-temperature and high-humidity environment; the reliance on a continuously running air-conditioning system not only increases the energy consumption of the lifeboat, but also, under long-term waiting conditions, this high-energy consumption mode will seriously weaken the equipment's endurance, bringing unnecessary risks to the rescue operation; when the external seawater temperature drops sharply, the fixed ventilation structure often cannot effectively isolate the external low temperature, but is prone to forming a cold bridge effect, causing the cabin temperature to drop sharply, further exacerbating the harshness of the crew's living environment. Summary of the Invention

[0004] The purpose of the present invention is to provide an underwater lifeboat air temperature and humidity control system and a control method thereof that actively changes the ventilation structure, and effectively solve the contradiction between ventilation efficiency and energy consumption control through an adjustable multi-duct system and a dynamic control method.

[0005] To achieve the above object, the technical solution provided by the present invention is:

[0006] An underwater lifeboat air temperature and humidity control system for actively changing ventilation structure, characterized by comprising: an underwater lifeboat wall, a ventilation duct, a movable ventilation baffle and a fan;

[0007] The underwater lifeboat bulkhead includes an outer underwater lifeboat bulkhead and an inner underwater lifeboat bulkhead. A ventilation cavity is formed between the outer underwater lifeboat bulkhead and the inner underwater lifeboat bulkhead. The ventilation cavity is divided into a plurality of ventilation ducts.

[0008] The interior of the underwater lifeboat is within the bulkhead, and an array of vents is provided on the bulkhead to connect the ventilation duct with the interior of the underwater lifeboat. The fan provides air to the interior of the lifeboat, and the interior of the lifeboat and the ventilation duct together form a circulating airflow path.

[0009] The movable ventilation baffle can move on the inner bulkhead of the underwater life-saving cabin, and as the position of the movable ventilation baffle changes, it can gradually block the ventilation ducts on the inner bulkhead of the underwater life-saving cabin step by step.

[0010] To optimize the above technical solution, the specific limitations adopted also include:

[0011] A plurality of groups of parallel ventilation partitions are arranged between the outer bulkhead and the inner bulkhead of the underwater life-saving cabin, and ventilation ducts are formed between adjacent ventilation partitions.

[0012] A ventilation baffle storage cabin is installed on the bulkhead of the underwater life-saving cabin, and the movable ventilation baffle is arranged in the ventilation baffle storage cabin and slides out of the ventilation baffle storage cabin when opened.

[0013] Furthermore, the movable ventilation baffle includes a left ventilation baffle and a right ventilation baffle, and the left ventilation baffle and the right ventilation baffle can slide independently to the left and right respectively to cover the inner bulkhead of the underwater life-saving cabin on the left side and / or the right side.

[0014] Furthermore, there are two ventilation baffle storage cabins, which are respectively used to store the left ventilation baffle and the right ventilation baffle; the ventilation baffle storage cabins are located above the internal space of the life-saving cabin; guide rails are provided in the ventilation baffle storage cabins, and the movable ventilation baffle is embedded on the guide rails through sliders.

[0015] Furthermore, fixing grooves for positioning the movable ventilation baffle are provided on the inner bulkhead of the underwater life-saving cabin, and fixing pins that can be installed in the fixing grooves are provided at the ends of the movable ventilation baffle for positioning the movable ventilation baffle to form a stepped ventilation opening degree array.

[0016] A fan partition is installed in the internal space of the life-saving cabin, the fan is installed outside the fan partition, and an air outlet connecting the fan is provided on the fan partition.

[0017] A life-saving cabin floor is installed in the internal space of the life-saving cabin, and the inner bulkhead and ventilation ducts of the underwater life-saving cabin are arranged above the life-saving cabin floor.

[0018] The present invention also provides a method for adjusting the air temperature and humidity of an underwater life-saving cabin with an actively changed ventilation structure, including the following steps:

[0019] Real-time monitor the air temperature and humidity parameters in the life-saving cabin;

[0020] Based on the real-time monitored air temperature and humidity parameters, select a ventilation mode according to the preset temperature and humidity thresholds, and the ventilation mode includes the following:

[0021] Adjust the shielding surface of the inner bulkhead of the underwater life-saving cabin on the left side and / or the right side by adjusting the position of the movable ventilation baffle to change the effective ventilation area, and at the same time, dynamically adjust the fan speed to match the current ventilation demand, forming a circulating air flow path between the internal space of the life-saving cabin and the ventilation duct to achieve directional heat exchange.

[0022] Furthermore, the ventilation mode sets three levels of temperature and humidity control intervals, corresponding to different adjustment schemes for the position of the movable ventilation baffle:

[0023] When the temperature exceeds 35°C and the humidity > 70%, start the maximum ventilation mode, retract all the movable ventilation baffles, and run the fan at full speed to enhance heat exchange;

[0024] When the temperature is in the range of 25 - 35°C, enable the adaptive adjustment mode, cover part of the ventilation openings on the inner bulkhead of the underwater life-saving cabin with the movable ventilation baffle, and run the fan at medium speed;

[0025] When the temperature < 25°C, switch to the heat preservation mode, cover all the ventilation openings on the inner bulkhead of the underwater life-saving cabin with the movable ventilation baffle, and stop the fan.

[0026] Furthermore, the present invention also has an emergency manual operation implementation. When the power is interrupted, the gradient extension amounts of the left and right ventilation baffles can be manually adjusted to change the ventilation volume to achieve the adjustment of the air temperature and humidity in the life-saving cabin.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] Through the design of the fixed slot of the movable ventilation baffle and the gradient opening array, the present invention can achieve step-by-step adjustment from fully opening the ventilation opening to fully closing the ventilation opening to form a heat preservation layer, covering all temperature and humidity conditions; by using the coordinated control of the fan and the ventilation duct, compared with the traditional air conditioning system, it makes full use of the structural cooling characteristics and is more energy-saving.

[0029] The present invention can select different temperature adjustment modes according to different usage situations, and has stronger applicability. Description of the Drawings

[0038] The present invention provides an air temperature and humidity regulation system and method for an underwater life - saving capsule with an actively changed ventilation structure, as Figures 1 to 3 shown.

[0039] In one embodiment of the present invention, an air temperature and humidity regulation system for an underwater life - saving capsule with an actively changed ventilation structure is proposed, including: an underwater life - saving capsule wall, a ventilation air duct 6, a movable ventilation baffle, and a fan 14;

[0040] The underwater life - saving capsule wall includes the outer - side outer cabin wall 1 of the underwater life - saving capsule and the inner - side inner cabin wall 2 of the underwater life - saving capsule. A ventilation cavity is formed between the outer cabin wall 1 and the inner cabin wall 2 of the underwater life - saving capsule, and the ventilation cavity is divided into several ventilation air ducts 6;

[0041] Inside the inner cabin wall 2 of the underwater life - saving capsule is the internal space of the life - saving capsule. A ventilation opening 7 for connecting the ventilation air duct 6 and the internal space of the life - saving capsule is provided on the inner cabin wall 2 of the underwater life - saving capsule; the fan 14 provides blowing for the internal space of the life - saving capsule, and the internal space of the life - saving capsule and the ventilation air duct 6 together form a circulating air flow path;

[0042] The movable ventilation baffle can move on the inner bulkhead 2 of the underwater life-saving cabin, and as the movable ventilation baffle 10 / 11 moves to different positions, it can gradually block the ventilation ducts 6 on the inner bulkhead of the underwater life-saving cabin in a stepped manner.

[0043] In some embodiments, the ventilation cavity between the outer bulkhead 1 and the inner bulkhead 2 of the underwater life-saving cabin is an annular cavity with a spacing of not less than 50 mm.

[0044] A plurality of groups of parallel ventilation partitions 5 are arranged between the outer bulkhead 1 and the inner bulkhead 2 of the underwater life-saving cabin, and ventilation ducts 6 are formed between adjacent ventilation partitions 5.

[0045] In some embodiments, a ventilation baffle storage cabin 9 is installed on the underwater life-saving cabin bulkhead, and the movable ventilation baffle is arranged in the ventilation baffle storage cabin 9 and slides out from the ventilation baffle storage cabin 9 when opened.

[0046] The movable ventilation baffle includes a left ventilation baffle 10 and a right ventilation baffle 11. The left ventilation baffle 10 and the right ventilation baffle 11 can slide independently to the left and right respectively to cover the inner bulkhead of the underwater life-saving cabin on the left side and / or the right side.

[0047] In some embodiments, there are two ventilation baffle storage cabins 9, which are respectively used to store the left ventilation baffle and the right ventilation baffle; the ventilation baffle storage cabins are located above the internal space of the life-saving cabin; guide rails are provided in the ventilation baffle storage cabins, and the movable ventilation baffle is embedded on the guide rails through sliders.

[0048] In some embodiments, the left ventilation baffle 10 and the right ventilation baffle 11 are made of multi-layer composite heat insulation materials and have a sliding guide rail structure; the driving device of the movable ventilation baffle can be any one of an electric push rod, a pneumatic actuator or a shape memory alloy driver.

[0049] Fixing grooves 8 for positioning the movable ventilation baffle are provided on the inner bulkhead of the underwater life-saving cabin.

[0052] In another embodiment, the present invention proposes a method for adjusting the air temperature and humidity in an underwater life-saving cabin with an actively changed ventilation structure, comprising the following steps:

[0053] Real-time monitor the air temperature and humidity parameters inside the life-saving cabin;

[0054] Based on the real-time monitored air temperature and humidity parameters, select a ventilation mode according to the preset temperature and humidity thresholds. The ventilation mode includes the following:

[0055] Adjust the shielding surface of the inner cabin wall of the underwater life-saving cabin on the left side and / or the right side by adjusting the position of the movable ventilation baffle, so as to change the effective ventilation area, and at the same time dynamically adjust the fan speed according to the current ventilation demand, form a circulating air flow path between the internal space of the life-saving cabin and the ventilation air duct, and achieve directional heat exchange.

The movable ventilation baffles cover some of the ventilation openings on the inner cabin wall of the underwater life-saving cabin, and the fan 14 runs at medium speed; in this mode, the left ventilation baffle 10 and the right ventilation baffle 11 partially extend and are positioned by fixed pins, forming an array of ventilation opening degrees with a gradient decrease, and realizing adjustable partition heat exchange;

[0059] When the temperature < 25°C, switch to the heat preservation mode. The movable ventilation baffles cover all the ventilation openings on the inner cabin wall of the underwater life-saving cabin, and the fan 14 stops working; in this mode, the left ventilation baffle 10 and the right ventilation baffle 11 are fully unfolded and cover all ventilation openings 7, and a static air heat preservation layer is formed in the ventilation air duct 6.

[0060] Among them, the ventilation mode can be controlled by an adjustment system. The adjustment system includes a central controller and temperature and humidity sensors installed at the top, middle, and bottom of the life-saving cabin respectively. The adjustment system is connected to the driving device of the movable ventilation baffle and the fan; the central controller automatically controls the telescopic amount of the baffle according to the data of the temperature and humidity sensors; further, the central controller can dynamically adjust the opening degree ratio of the ventilation opening through intelligent algorithms such as PID.

[0061] In some embodiments, the fan is a variable-frequency fan, equipped with a variable-frequency speed regulation device and an air volume sensor.

[0062] In some embodiments, the present invention also has an emergency manual operation mode. When the power is interrupted, the gradient extension amounts of the left and right ventilation baffles can be manually adjusted to change the ventilation volume and achieve the air temperature and humidity in the rescue cabin.

[0063] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention.
