Description

A kind of submarine simulator

Technical field

The utility model is related to buoyancy demonstration equipment innovative technology field, especially a kind of submarine simulators.

Background technology

Submarine is a kind of submariner naval vessels using law of buoyancy, has water tank in shell, when needing to rise, is utilized Water in water tank is discharged high pressure gas, and buoyancy is made to be more than gravity, and submarine rises at this time, when needing dive, extracts high pressure out Gas makes the water in water tank increase, and buoyancy is made to be less than gravity, at this time submarine dive.Student is to the rising of submarine and dive Principle is very interested, but is demonstrated without suitable teaching aid, and existing frequently-used includes following several：1. closing bath bottle One unit of plastic of interior placement and counterweight, extrusion bottle make unit of plastic rising or dive；2. it is arranged on frame using plastic film, By whole submerged, the degree of plastic film indent is observed.In addition to this there are other several experiments, but there is demonstration effect Fruit is intuitive, the unsatisfied problem of student.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, providing can be inflated or air-breathing carrys out simulated diving Ship rises or the intuitive a kind of submarine simulator of dive process and demonstrating effect.

The technical scheme adopted by the utility model is that：

A kind of submarine simulator, it is characterised in that：Including transparent water tank, vial, it is evacuated pump-up device and counterweight, Filling clear water in water tank, filling air and fluid and bottle mouth position bottle stopper beyond the Great Wall, are embedded in tracheae and water pipe on bottle stopper in vial, Tracheae stretches into the end in vial and is inverted into water after bottom of bottle, vial bottleneck lifting counterweight, and the tracheae passes through Pump-up device is evacuated described in pipeline connection, the water pipe stretches into the end in vial and is located at inverted vial inner fluid liquid level Top, water pipe makes the inside and outside connection of vial, and the pumping pump-up device by the extraction of the air in vial or can be squeezed into, air Clear water enters from water pipe in vial when extraction, and clear water is from outside water pipe discharge vial when air is squeezed into.

Moreover, the inverted vial upper end connects the suspension hook of a spring scale, spring scale upper end connection by suspender belt The fixture of one crossbeam one end, the crossbeam other end connect a sliding sleeve, which is sleeved on a holder, which is mounted on On substrate.

The advantages of the utility model and good effect are：

In the utility model, vial is swum in by the way that counterweight is inverted in the water of water tank, due to depositing for the air in bottle Water cannot be introduced into bottle, and when extracting air out, pressure reduces in bottle, and water enters from water pipe in bottle, and vial integrally weighs at this time Amount becomes larger, and can gradually sink, and when vial is fully immersed in water and when gravity is identical as buoyancy, vial can be suspended in water Different depth at, when squeezing into air, pressure becomes larger in bottle, water from water pipe discharge bottle outside, at this time vial overall weight become It is small, it can be gradually increasing, when the substantially the entirety of discharge of water, vial swims in the water surface, and fluid is in addition also filled in bottle, the oil Liquid color is deeper, can serve to indicate that water enter number, the above process makes student be observed that the effect of empty gas and water makes glass Glass bottle rises or the process of dive, very intuitive.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is that air is extracted out in the vial of Fig. 1, the schematic diagram that water enters.

Specific implementation mode

With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model , the scope of protection of the utility model cannot be limited with following embodiments.

A kind of submarine simulator, as shown in Figure 1, 2, the innovation of the utility model are：Including transparent water tank 10, glass Glass bottle 13, pumping pump-up device and counterweight 16, water tank is interior to fill clear water 11, and air and fluid 14 and bottleneck 17 are filled in vial Locate bottle stopper 18 beyond the Great Wall, is embedded in tracheae 12 on bottle stopper and water pipe 19, tracheae stretch into the end in vial close to bottom of bottle, vial Bottleneck is inverted into after lifting counterweight by hoist cable 20 in water, and tracheae is connected to pumping pump-up device by pipeline 15, and water pipe stretches into End in vial is located at the top of inverted vial inner fluid liquid level, and water pipe makes the inside and outside connection of vial, pumping inflate Air in vial can be extracted out or squeezed by device, and clear water enters from water pipe in vial when air is extracted out, when air is squeezed into Clear water is from outside water pipe discharge vial.

In the present embodiment, inverted vial upper end connects the suspension hook 8 of a spring scale 7, the spring scale upper end by suspender belt 9 The fixture 5 of 4 one end of a crossbeam is connected by connecting rope 6, which connects a sliding sleeve 2, which is sleeved on one On holder 3, a jackscrew 1 for fixing is arranged in sliding sleeve, and holder is installed on the base plate (21, and water tank is also disposed on substrate.

Vial is swum in by the way that counterweight is inverted in the water of water tank, and due to the presence of the air in bottle, water cannot be introduced into In bottle, fluid can use the heavier oil of color, be used to indicate into the water in bottle number.

When the utility model is demonstrated：

1. when extracting air out, pressure reduces in bottle, and water enters from water pipe in bottle, and vial overall weight becomes larger at this time, Can gradually it sink；

2. continuing to extract air out, when vial is fully immersed in water and when gravity is identical as buoyancy, vial can hang It floats at the different depth of water；

3. when squeezing into air, pressure becomes larger in bottle, and water is from outside water pipe discharge bottle, and vial overall weight becomes smaller at this time, It can be gradually increasing；

The above process makes student be observed that the effect of empty gas and water makes the process of vial rising or dive, very Intuitively.
