Description

A kind of plant cultivation equipment that is arranged in the manned spacecraft

Technical field

The utility model relates to a kind of equipment that increases oxygen content, minimizing carbon dioxide content in for a long time manned spacecraft for spacefarer's accommodation.

Background technology

Current, the oxygen concentration of air is designed to 30% mostly in the manned spacecraft, and remaining 70% is nitrogen.Report according to the study, when airborne oxygen concentration 18% to 30% the time, ought to satisfy the spacefarer and keep healthy physiological requirements.But, must control simultaneously gas concentration lwevel below 1%.Because when carbon dioxide in air reaches 2%～10%, the people is had a headache, elevation of blood pressure, heavy then cause people stupor, in addition dead.The space is narrow and small in the spacecraft, gas concentration lwevel very easily takes place exceed standard.For this reason, current manned spacecraft mostly in the air cleaning of life-support systems and oxygen supply facility Mining remove carbonic acid gas with the peroxide of lithium hydroxide or alkalinous metal or, then handled with the method for chemistry or physics again with solid amine molecular sieve collection carbonic acid gas.Alkaline metal salt that these class methods produce and spacefarer's excreta and various life, work rubbish all can pollute space capsule.So, eliminate carbonic acid gas with physics, chemical method, from environmental angle, real non-very wise move.And the photosynthesis of plant in process of growth can absorbing carbon dioxide, produces oxygen, just the needs of manned spacecraft internal environment.Therefore, at the equipment that the manned spacecraft internal equipment can be cultivated plant, realizing that plant inhales carbon system oxygen, is the desirable approach that solves purification of space capsule Carbon Dioxide in Air and oxygen supply problem.

The utility model content

The purpose of this utility model provides a kind of being installed in the long-term manned spacecraft, is used for the equipment of cultivated plant.

A kind of technical scheme that is arranged at the plant cultivation equipment in the manned spacecraft of the utility model is: it totally is basket shape, and its structure comprises net basket, waterproof membrane, plant culture matrix layer and water supply piping.Wherein, net the framework that basket constitutes the utility model plant cultivation equipment, use wire rod or lathwood with certain rigidity to make, that nets basket is network structure with the bottom all around, opening suitable for reading.The net basket totally can be box-shaped, circle pier shape or bucket shape.The mesh aperture of net basket wall is 2～30mm.Wherein, the large-meshed net basket of aperture 20～30mm is suitable for cultivating evergreen turf or general greenhouse vegetables and fruits flowers and trees, and the fine-structure mesh basket of aperture 2～4mm is suitable for cultivating the duckweed algae.

Attach waterproof membrane at net basket inwall.The film that waterproof membrane is to use impermeable material to make.

In the formed space of waterproof membrane inwall the plant culture matrix layer is set, laying or accumulation are suitable for the matrix of plant growing.

Lay the water supply piping in plant culture matrix, feed pipe is fastened the water source of holding with in the manned spacecraft and is connected, and the water pipe section that is positioned at plant culture matrix is provided with osculum.

As optimization, the utility model also is provided with the reinforcement frame, combines with the net basket, with the rigidity of reinforcing mat basket.The rigidity of reinforcement frame is higher than the net basket.The simplest and easy effective reinforcement frame is and suitable for reading the adapting of net basket, with the close carriage that attaches in net basket edge suitable for reading.The reinforcement frame can also as be netted the assembling of basket skeleton: the reinforcement frame has suitable for reading, with the attaching suitable for reading of net basket; The reinforcement frame has end opening, combines with net basket bottom periphery; Between the suitable for reading and end opening of reinforcement frame column is set, the reinforcement frame that is arranged at box-shaped and bucket shape net basket is provided with column at four jiaos, the reinforcement frame that is arranged at round pier shape net basket around 2-5 column is set.

The use of reinforcement frame can be received the effect of two aspects: the one, and the rigidity of raising entire equipment; The 2nd, can reduce the rigidity of making the employed material of net basket, reduce the quality of material therefor, might alleviate the weight of entire equipment on the whole.

As optimization, the net formula cover layer that adds suitable for reading that the utility model also opens wide at net basket to prevent that plant culture matrix and water body are elegant under weightlessness, also is limited in plant growing in the basket simultaneously.

In manned spacecraft, use the vigorous plant of the utility model plant cultivation equipment cultivation photosynthesis, utilize the normal illumination of spacefarer's accommodation, or utilize the daylight that to collect, perhaps be that the energy is the ad hoc illumination of plant of being cultivated with solar energy, absorbing carbon dioxide in growing process, discharge oxygen, replace existing physico-chemical process to a certain extent, subtract carbon oxygenation problem in the solution space capsule.

On the basis of the utility model plant cultivation equipment, by integrating equipment such as existing waste water reclamation, carbohydrate processing, biological degradation, supply of electric power in the spacecraft, realize spacefarer's excreta, defecation thing and various life, the biologically digesting of work rubbish, then realize the optimum reversible reaction of biological cycle regenerative in the space capsule, the final astroplankton chain that forms solves the space capsule environmental issue.
