Problems solved by technology
[0004] 1. The traditional ocean current simulation method is relatively simple, which cannot make students have a deep impression on it, making students not fully aware of ocean currents
[0005] 2. The traditional ocean current simulation cannot move and express it freely, and the whole device cannot be moved easily, resulting in certain invariance

The invention discloses an ocean current simulating device for geography teaching. The device comprises a bracket and an iron plate. The outer wall of bottom of the bracket is provided with roller through bolts. One end of top of the bracket is provided with a bearing which is welded. The other end of the bearing is provided with a supporting rod which is welded. One end, which is far from the bearing, of the supporting rod is welded on one side of the iron plate. A map is adhered to one side of the iron plate. An ocean current simulating structure is adhered to the map side. A body is packaged in the iron plate. According to the ocean current simulating device, the position of a specific ocean current in the map can be vividly represented through the simulating structure where the iron plate clings to the map, thereby realizing vividness and convenient memory, and realizing deep impression of the student to the ocean current. Because arrangement of the bearing, the body comprises theiron plate and the map can be freely turned, thereby increasing utilization rate. The bottom of the bracket is provided with rollers, thereby facilitating device movement. Because of arrangement of apencil box and an object placing box, storing of objects and pens is facilitated, thereby facilitating popularization.
Description
technical field [0001] The invention relates to the technical field of geography teaching, in particular to an ocean current simulation device for geography teaching. Background technique [0002] Ocean current, also known as ocean current, refers to the large-scale flow of sea water along a certain path in addition to the tidal movement caused by tidal force in the ocean. The main driving force of the movement of ocean currents is wind, and it can also be the inhomogeneity of seawater density distribution caused by thermal-salinity effect. The former is expressed as the wind stress acting on the sea surface, and the latter is expressed as the horizontal pressure gradient force in seawater. Coupled with the effect of the geostrophic deflection force, the seawater has both horizontal flow and vertical flow. The prevailing wind is the main driving force of wind and sea currents. Due to the blocking and friction between the coast and the seabed, the performance of ocean curr...
