Description

A kind of ocean current teaching demonstration device
Technical field
The utility model is related to a kind of teaching aid, more particularly to a kind of ocean current teaching demonstration device.
Background technology
Ocean current is also known as in ocean current, ocean in addition to the tidal motion as caused by power to lead tide, big rule of the seawater along certain approach Mould flows.Air motion and wind band near the ground are ocean water body main movement power, different according to Crack cause, and ocean current can be divided into Wind current, density current, compensation stream three types, among geographical teaching, teacher explanation ocean current forming process with influence because When plain, because no teaching aid can only word picture, it is impossible to intuitively see very much, waste time and energy.
Utility model content
Technical problem to be solved in the utility model is:A kind of ocean current teaching demonstration device is provided, tradition explanation is solved Indigestibility, the problem of not directly perceived not vivid.
The technical scheme that the utility model is used by solution the problem of set forth above is:
A kind of ocean current teaching demonstration device, including demonstration box 1, ball float 2, baffle plate 3, blower fan 4, heater 5, the and of densitometer 6 Set in thermometer 7, demonstration box 1 and baffle plate 3 is set in the middle of several ball floats 2, demonstration box 1, the left upper part of demonstration box 1 sets blower fan 4, the left end bottom of demonstration box 1 sets heater 5, and the both sides of baffle plate 3 are respectively provided with thermometer 7 and densitometer 6, thermometer 7 and densitometer 6 On the front inner wall for being arranged at demonstration box 1.
Filling salting liquid, salting liquid simulated seawater in described demonstration box 1.
Described demonstration box 1 is glass box, the concrete condition in convenient observation demonstration box.
The described middle part of demonstration box 1 sets the seal groove 8 being engaged with baffle plate 3, and baffle plate 3 is arranged on by seal groove 8 and drilled Show in case 1, baffle plate can control salting liquid motion, the anti-baffle plate both sides salting liquid mixing of seal groove.
The described upper end of baffle plate 3 sets draw ring 9, facilitates the dismounting of baffle plate.
Described ball float 2 is made up of the different material of density, can be suspended in the different height in salting liquid.
Described ball float 2 is colored ball float.
Operation principle of the present utility model:When simulating wind current, the baffle plate in the middle of demonstration box is taken out, blower fan, observation is opened The mobility status of each layer ball float in salting liquid;When simulating density current, heater is opened, is higher than the salting liquid temperature on the left of baffle plate The temperature of salting liquid, the variable density of viewing hood both sides salting liquid on the right side of baffle plate, take out each layer in baffle plate, observation salting liquid and float The mobility status of ball;During analog compensation stream, the salting liquid of baffle plate side is taken out, simulated caused by wind or other reasonses Sea-level drop, takes out the mobility status of each layer ball float in baffle plate, observation salting liquid.
The beneficial effects of the utility model are:1st, it is simple in construction, it is easy to operate;2nd, image is demonstrated, increases learning interest, Strengthen memory;3rd, teacher's explanation is easy, saves the time;4th, ball float more intuitively watches the mobility status of simulated seawater.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- demonstration boxs, 2- ball floats, 3- baffle plates, 4- blower fans, 5- heaters, 6- densitometers, 7- thermometers, 8- sealings Groove, 9- draw rings.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
Reference picture 1, a kind of ocean current teaching demonstration device described in present embodiment, including demonstration box 1, ball float 2, gear Set in plate 3, blower fan 4, heater 5, densitometer 6 and thermometer 7, demonstration box 1 and gear is set in the middle of several ball floats 2, demonstration box 1 Plate 3, the left upper part of demonstration box 1 sets blower fan 4, and the left end bottom of demonstration box 1 sets heater 5, and the both sides of baffle plate 3 are respectively provided with thermometer 7 and densitometer 6, thermometer 7 and densitometer 6 are arranged on the front inner wall of demonstration box 1.
Filling salting liquid, salting liquid simulated seawater in described demonstration box 1.
Described demonstration box 1 is glass box, the concrete condition in convenient observation demonstration box.
The described middle part of demonstration box 1 sets the seal groove 8 being engaged with baffle plate 3, and baffle plate 3 is arranged on by seal groove 8 and drilled Show in case 1, baffle plate can control salting liquid motion, the anti-baffle plate both sides salting liquid mixing of seal groove.
The described upper end of baffle plate 3 sets draw ring 9, facilitates the dismounting of baffle plate.
Described ball float 2 is made up of the different material of density, can be suspended in the different height in salting liquid.
The operation principle of present embodiment:When simulating wind current, the baffle plate in the middle of demonstration box is taken out, blower fan is opened, Observe the mobility status of each layer ball float in salting liquid;When simulating density current, heater is opened, makes the salting liquid temperature on the left of baffle plate Higher than the temperature of salting liquid on the right side of baffle plate, the variable density of viewing hood both sides salting liquid is taken out each in baffle plate, observation salting liquid The mobility status of layer ball float;During analog compensation stream, the salting liquid of baffle plate side is taken out, simulation is made because of wind or other reasonses Into Sea-level drop, take out baffle plate, the mobility status of each layer ball float in observation salting liquid.
The beneficial effect of present embodiment is:1st, it is simple in construction, it is easy to operate;2nd, image, increase study are demonstrated Interest, strengthens memory;3rd, teacher's explanation is easy, saves the time;4th, ball float more intuitively watches the mobility status of simulated seawater.
Specific embodiment of the utility model is not constituted to limitation of the present utility model, every to use phase of the present utility model Like structure and change, in protection domain of the present utility model.
