Description

artificial satellite model

technical field

The utility model relates to the field of popular science education, in particular to an artificial satellite model.

Background technique

With the use of various satellites, more and more people are curious about the structure and operation of satellites. Artificial satellites are one of the exhibits in the space exploration exhibition area of the Science and Technology Museum.

Chinese patent CN206224887U discloses a science teaching aid for Beidou navigation satellite assembling model. However, the real artificial satellite is suspended in space, and it is difficult for any directly connected artificial satellite model to simulate the real suspended satellite state, which increases the difficulty of children's cognition of the way satellites work.

Utility model content

The purpose of the present invention is to provide an artificial satellite model that can be suspended.

In order to achieve the above purpose, the technical scheme adopted by the present invention is as follows: an artificial satellite model, comprising a model body arranged above the base, the model body and the base form a magnetic levitation support, the base is embedded with a ring-shaped permanent magnet, and the model body is A permanent magnet block is embedded in the lower part, and the lower surface of the permanent magnet block has different magnetic poles from the upper surface of the permanent magnet.

In the above scheme, supporting the artificial satellite model by means of magnetic levitation can more intuitively display the actual working status of the satellite, which is beneficial for visitors to understand the working principle of the satellite. The artificial satellite model in this application can be used as a display in a science and technology museum or as a toy souvenir for children to learn and display.

Detailed ways

An artificial satellite model includes a model body 20 arranged above the base 10, the model body 20 and the base 10 form a magnetic suspension support, the base 10 is embedded with a ring-shaped permanent magnet 11, and the lower part of the model body 20 is embedded with a permanent magnet block, The lower surface of the permanent magnet block has different magnetic poles from the upper surface of the permanent magnet 11 , and the inner circle of the permanent magnet 11 is provided with an electromagnetic coil 12 or a permanent magnet structure whose upper surface magnetic pole is different from that of the permanent magnet 11 .

In the above scheme, supporting the artificial satellite model by means of magnetic levitation can more intuitively display the actual working status of the satellite, which is beneficial for visitors to understand the working principle of the satellite. The artificial satellite model in this application can be used as a display in a science and technology museum or as a toy souvenir for children to learn and display. The principle of magnetic levitation in this application is that the electromagnetic coil 12 and the permanent magnet block repel and support the model body 20 to overcome gravity, while the permanent magnet 11 attracts the permanent magnet block to pull the circumferential direction of the model body 20, preventing the repulsive force from driving the model body 20 to overturn and overturn. .

The electromagnetic coil 12 has a current that changes in magnitude in a floating manner. The size of the repulsive force is changed by changing the magnitude of the current, so as to realize the up and down movement of the model body 20, and the floating current will cause the model body 20 to float up and down, making the model more attractive and more effective for children's science education. Purpose.

A permanent magnet 11 and an electromagnetic coil 12 are arranged in the box cavity of the lower seat body 13 of the base 10 , and a cover plate 14 that is detachably matched with the box mouth of the lower seat body 13 is arranged. The internal permanent magnet 11 and the electromagnetic coil 12 can be directly exposed through disassembly and assembly, so that the principle of the magnetic levitation structure can be easily shown to children. The use of a transparent material for the cover plate 14 in the present application can also achieve the same purpose.

Four electromagnetic coils 12 are arranged around the axis of the annular permanent magnet 11 . Four can generate four repulsive forces, and by changing the magnitude of the current in each coil, a slight difference in the magnitude of the repulsive force can be achieved, so that the model body 20 is tilted to a certain extent to simulate a real artificial satellite with a tilted attitude.

The model body 20 and the base 10 are made of insulating materials. It prevents the model body 20 and the base 10 from cutting the magnetic field lines to cause current to interfere with the device itself.

The solar panel model 21 on the model body 20 forms a detachable fit with the model body 20 . Since the present application can be sold as a toy souvenir, it needs to be packaged. The model body 20 containing the solar panel model 21 is bulky and the solar panel model 21 is at risk of being broken, so it needs to be packaged in a disassembled manner.

The root edge of the solar panel model 21 is a reverse wedge bar 211 structure, and the reverse wedge bar 211 of the solar panel model 21 and the reverse wedge groove 22 on the model body 20 form a plug fit. The solar panel model 21 installation structure similar to building blocks can improve the playability of the artificial satellite model and enhance children's hands-on ability.
