Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to a simulated water tank for demonstrating the flow of ocean currents. Background Art

[0002] Ocean currents, also known as ocean surface currents, refer to the regular horizontal flow of seawater with a relatively stable speed along a certain direction. They are large-scale non-periodic movements from one sea area horizontally or vertically to another sea area. They are the main form of movement of seawater. Ocean currents are distributed in low, medium and high latitudes. Three ocean current patterns are deduced from the planetary wind system theory, namely the equatorial circulation, subtropical circulation and subpolar circulation. Ocean currents can be divided into three categories according to their causes: friction currents, gradient currents and tidal currents. Gradient currents are gravity-pressure gradient currents, including oblique currents, density currents and supplementary currents. Ocean currents can also be divided into warm currents and cold currents according to the temperature of the flowing seawater. Warm currents are warmer than the water temperature in the sea area they flow through, and cold currents are colder than the water temperature in the sea area they flow through. In geography teaching, when teachers explain the formation process and influencing factors of ocean currents, they can only describe them verbally without teaching aids, and cannot see them intuitively, so it takes time and effort to understand them. Therefore, it is very necessary to design a simulated water tank that is practical and can be demonstrated intuitively to demonstrate the flow of ocean currents. Utility Model Content

[0010] According to the above technical solution, the outer wall surface of the circular sealing cover is flush with the outer wall surface of the transparent observation window, and screw grooves are evenly distributed around the circumference of the circular sealing cover.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model is provided with an ocean current simulation box, and geography teachers can simulate the flow of ocean currents through the ocean current simulation box during geography teaching, and demonstrate to students; the interior of the ocean current simulation box is a closed environment, and the sealed isolation plate separates it into a pair of identical ocean current simulation areas, and the sealed isolation plate can be conveniently withdrawn to simulate the flow of ocean currents; the interior is filled with salt solutions, and the salt solutions can be appropriately added and reduced according to the simulation of the ocean currents, and the liquid is respectively inletted and outletted through the liquid inlet pipe and the liquid outlet pipe, and the inclined surface is used to control the flow of ocean currents.

The flow of seawater caused by this can be simulated by using components such as ventilation fans, barometers, exhaust pipes, and vacuum pumps. The density flow is caused by the uneven density distribution and tilted sea surface due to different seawater temperatures and salinities. The density flow can be simulated by using components such as densitometers, liquid inlet pipes, liquid outlet pipes, and heating pipes. The flow of the internal floating ball can be clearly observed through the transparent observation window, which helps students better understand the flow of ocean currents. More intuitive and clear observations make it easier for students to learn and understand ocean currents. The sealing isolation plate can be pulled out by the plate, and the handle plate is placed in the embedded groove, which can increase the flatness and aesthetics of the upper end surface of the ocean current simulation box. The elastic force of the spring can make the arc-shaped clamping joint at one end of the movable block installed in the corresponding arc-shaped clamping groove, and the stability of the handle plate is reinforced to prevent the sealing isolation plate from shaking and causing unstable isolation during the ocean current simulation process. The ocean current simulation box can be stably supported by the supporting legs, which is convenient for the demonstration of ocean current flow. After the demonstration, a control device is installed outside, and the cylinder can be controlled by the control device, and then the universal wheel can be controlled to rise and fall, which is convenient for the displacement and storage of the ocean current simulation box.
