Abstract
The utility model provides an experimental apparatus capable of realizing ups and downs of a submarine in the water by air controlling and water feeding and discharging by push-and-pull of a piston. The submarine experiment demonstrator includes a submarine shell, an air control cabin, a piston, a push-pull rod, a handle, counter weight metal strips, and a seal door. The submarine experiment demonstrator is characterized in that the sealed submarine model shell is made of transparent plastic, the top is provided with a closed sealed door for increasing or decreasing counter weight metal strips to adjust the weight of the submarine experiment demonstrator, the bottom is provided with the cylindrical air control cabin, the piston is arranged in the cabin, and when the piston is in the center of the air control cabin, the buoyancy of the submarine in the water is equal to the weight of the submarine. The push-pull rod in the air control cabin is connected with the piston, the push-pull rod is provided with the handle, and the handle is controlled to pull the piston to control water in the cabin. When much water and small amount of air exist in the air control cabin, the weight of the submarine increases and the submarine sinks, and when small amount of water and much air exist in the air control cabin, the submarine ascents.
Description
Technical field
The submarine experiment demonstrator relates to a kind of air and controls storehouse, piston push-and-pull water inlet draining, realizes submarine rises and falls in water experimental provision, belongs to physics subject---the teaching aid in the experiment teaching instrument of school science, learning aid.
Background technology
The submarine experiment demonstrator that deposit in existing teaching material and school instrument room is all not have the container of sealing to make submarine with one, air is not set controls storehouse, but with a long flexible pipe, syringe and submarine are coupled together, during experiment, air in syringe is pressed into the submarine the inside makes the submarine floating, then air is extracted out submarine is sunk.The sink-float principle of the submarine in this and reality has very large difference, there are a lot of doubtful points, submarine should be hermetic, the inside can not intake, submarine is provided with air bin, and after air bin is filled water, submarine sinks, submarine floating after the water of discharge air bin, rather than people outside is pressed into air after submarine and makes the submarine floating by a pipe, and the air of extracting the submarine the inside out sinks submarine.
Summary of the invention
the utility model submarine experiment demonstrator, provide a kind of air to control, piston push-and-pull water inlet draining, realize submarine rises and falls in water experimental provision, comprise the submarine shell, air is controlled storehouse, piston, pull bar, handle, the counterweight bonding jumper, hermatic door, it is characterized in that: the Submarines model shell of the sealing that transparent plastic is made, top is provided with the hermatic door of a sealing, be used for adding the counterweight bonding jumper, bottom is provided with columniform air and controls storehouse, be provided with piston in storehouse, the counterweight bonding jumper lies in the submarine inner bottom part, when piston is positioned at center, air control storehouse, make submarine is subject in water buoyancy equal the deadweight of submarine, push away, draw piston, submarine rises and falls up and down in water.Air is controlled pull bar in storehouse and is connected with piston, and pull bar is provided with handle, and control crank pulls piston to control the water yield in storehouse back and forth, and air is controlled the many little airs of the water yield in storehouse, conduct oneself with dignity increase and sinking of submarine, in air control storehouse the water yield less air float at most.
Description of drawings
Accompanying drawing 1 is submarine experiment demonstrator installation drawing.By sequence number: 1. Submarines model shell, 2. air is controlled storehouse, 3. piston, 4. pull bar, 5. handle, 6. counterweight bonding jumper, 7. hermatic door.
Embodiment
the submarine experiment demonstrator provides a kind of air to control storehouse, piston push-and-pull water inlet draining, realize submarine rises and falls in water experimental provision, comprise the submarine shell, air is controlled storehouse, piston, pull bar, handle, the counterweight bonding jumper, hermatic door, it is characterized in that: the Submarines model shell (1) of the sealing that transparent plastic is made, be provided with the hermatic door (7) of a sealing, bottom is provided with columniform air and controls storehouse (2), be provided with piston (3) in storehouse, the counterweight bonding jumper is used for the ratio of balance submarine suffered buoyancy and submarine deadweight in water, the buoyancy that is subject to greatly as the Submarines model volume is many, should add the counterweight bonding jumper, make the deadweight of submarine is subject in water buoyancy and submarine about equally.Air is controlled pull bar (4) in storehouse and is connected with piston, and pull bar is provided with handle (5), control crank, pull back and forth the water yield in piston control storehouse, piston all is advanced to the end, air is pressed in submarine, air is controlled the water yield in storehouse and is increased, the submarine deadweight increases, the deadweight of submarine is sunk greater than the buoyancy that is subject to, and piston is pulled on the submarine limit, and air is controlled discharge reduction in storehouse, the deadweight of submarine reduces, and the deadweight of submarine is floated less than suffered buoyancy.
Claims (1)
1. submarine experiment demonstrator, provide a kind of air to control, piston push-and-pull water inlet draining, realize submarine rises and falls in water experimental provision, comprise the Submarines model shell, air is controlled storehouse, piston, pull bar, the counterweight bonding jumper, it is characterized in that: the Submarines model shell of sealing, bottom is provided with columniform air and controls storehouse, be provided with piston in storehouse, in storehouse, pull bar is connected with piston, the counterweight bonding jumper lies in the submarine inner bottom part, when piston is positioned at center, air control storehouse, make submarine is subject in water buoyancy equal the deadweight of submarine, push away, draw piston, submarine rises and falls up and down in water.
