Description
Technical field
This utility model relates to the apparatus for demonstrating of ocean natural phenomena, refers in particular to the apparatus for demonstrating of a kind of seawater salinity and ocean current relation.
Background technology
Ocean occupies 70.8% that earth surface is long-pending, immeasurable natural resources is contained in ocean, such as the biology in sea water, chemical element, energy and the heat of storage produced by wave, tide and seawater movement, strand and abyssalbenthic mineral resources etc., in marine resources development early strategic plan written into most strands countries, but, the premise that can utilize and develop ocean is that marine environment carries out deep understanding and enough talents reserves, therefore the teaching and universal become focus of ocean knowledge.
Ocean current is also known as ocean current, in ocean in addition to the tidal motion caused by power to lead tide, sea water is along the extensive flowing of certain approach, ocean current plays important role to weather and the ecological balance of the earth, ocean current follows certain route and moves again and again, its scale then to go out greatly thousands of times compared with the huge Jiang great Chuan of land, sea water flowing can promote turbine generation, green energy resource is carried for people, the ocean current energy of China is the abundantest, and the theoretical mean power along ocean current is 1.4 hundred million kilowatts.The factor causing ocean current to move can be wind, it can also be the inhomogeneities of the density of sea water distribution that hot salt effect causes, the former shows as acting on the wind-stress on sea, the latter shows as the horizontal gas pressure gradient power in sea water, the ocean current that wherein salt effect is formed is referred to as density current, and the difference of different waters seawater salinity can make density of sea water produce difference, thus causes the difference of sea level fluctuations, between two marine sites that density of sea water is different, just create the inclination on sea, cause the flowing of sea water.
While ocean carries abundant natural resources, also contain all danger, vast majority of people can not witness these natural wonders the most personally, therefore to demonstrate out intuitively by seawater salinity and ocean current relation, it is easy to the understanding ocean current phenomenon of people's intuitive, the present inventor works out the apparatus for demonstrating of a kind of seawater salinity and ocean current relation especially, and this case thus produces.
Utility model content
The purpose of this utility model is the apparatus for demonstrating providing a kind of seawater salinity with ocean current relation, its simple in construction, seawater salinity and ocean current is formed relation and demonstrates out intuitively, make ocean current knowledge-transference embody, visualize, should be readily appreciated that.
To achieve these goals, the technical solution of the utility model is as follows:
Seawater salinity and the apparatus for demonstrating of ocean current relation, including the first tank, the second tank, upper communicating pipe and lower communicating tube；Described first tank fills coloured saline solution of high concentration, second tank fills the colourless saline solution of colourless deionized water or low concentration, first tank upper end is connected by described upper communicating pipe with the second tank upper end, first tank lower end is connected by lower communicating tube with the second tank lower end, and described first tank and the second tank are made by transparent material.
Described upper communicating pipe and lower communicating tube are respectively provided with water valve.
Described upper Diameter of connecting pipe is less than lower communicating tube caliber.
It is respectively provided with a Density Measuring Instrument in described first tank and the second tank.
After using such scheme, utility model works principle is as follows: load coloured saline solution (simulation high density marine site) of high concentration in the first tank, second tank loads the colourless saline solution (simulation low-density marine site) of colourless deionized water or low concentration, the solution of the first tank upper end is by flowing into the second tank upper end (simulation density current) upper communicating pipe, the solution/water of the second tank flows into the first tank lower end by lower communicating tube from lower end, realize flow and supplement (simulated sea bottom backflow/undercurrent), by the flowing of colored solutions, observer can pass through the first tank and the second tank sees the process that density current is formed intuitively.
The beneficial effects of the utility model are: this utility model simple in construction, easy to operate, demonstrate out intuitively by the forming process of density current, ocean knowledge is made to teach materialization, visualization, can be applied in education and instruction as teaching aid, it is simple to student understands, the efficient teaching method for subjects such as oceans provides support, can also be applied in the ocean knowledge universal education place such as aquarium, science and technology center, it is easy to masses accept and understand ocean current phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label declaration
First tank 1, the coloured saline solution of high concentration 11, the second tank 2, colourless deionized water or the colourless saline solution of low concentration 21, upper communicating pipe 3, lower communicating tube 4, water valve 5, Density Measuring Instrument 6.
Detailed description of the invention
As it is shown in figure 1, the seawater salinity of this utility model announcement and the apparatus for demonstrating of ocean current relation, including first tank the 1, second tank 2, upper communicating pipe 3 and lower communicating tube 4；Described first tank 1 fills coloured saline solution 11 of high concentration, second tank 2 fills the colourless saline solution 21 of colourless deionized water or low concentration, first tank 1 upper end is connected by described upper communicating pipe 3 with the second tank 2 upper end, first tank 1 lower end is connected by lower communicating tube 4 with the second tank 2 lower end, and described first tank 1 is made by transparent material with the second tank 2.
This utility model presentation process is as follows: the coloured saline solution 11(loading high concentration in the first tank 1 simulates high density marine site), second tank 2 loads the colourless saline solution 21(of colourless deionized water or low concentration and simulates low-density marine site), the solution of the first tank 1 upper end is by flowing into the second tank 2 upper end (simulation density current) upper communicating pipe 3, the solution/water of the second tank 2 flows into the first tank 1 lower end from lower end by lower communicating tube 4, realize flow and supplement (simulated sea bottom backflow/undercurrent), by the flowing of colored solutions, observer can pass through the first tank 1 and the second tank 2 sees the process that density current is formed intuitively.
In the present embodiment, it is respectively provided with a water valve 5 in described upper communicating pipe 3 on lower communicating tube 4, by water valve 5 switch upper communicating pipe 3 and lower communicating tube 4, controls the flowing of solution/water, to control the progress of density current presentation process.Wherein, described upper communicating pipe 3 caliber is less than lower communicating tube 4 caliber.
In order to demonstrate out the change of solution density in the first tank 1 and the second tank 2 further, in described first tank 1 and the second tank 2, it is respectively provided with a Density Measuring Instrument 6.
This utility model simple in construction, easy to operate, just demonstrate out intuitively by the forming process of density current merely with two tanks and communicating pipe, ocean knowledge is made to teach materialization, visualization, can be applicable in education and instruction, it is simple to student understands, the efficient teaching method for subjects such as oceans provides support, can also be applied in the ocean knowledge universal education place such as aquarium, science and technology center, it is easy to masses accept and understand ocean current phenomenon.
These are only specific embodiment of the utility model, not the restriction to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, each fall within the protection domain of this case.
