Black hole knowledge-related interactive experience device

Technical Field

The application relates to the technical field of popular science exhibits, in particular to a black hole knowledge-related interactive experience device.

Background

The science and technology center (short for science and technology center) is a public welfare science popularization education institution taking exhibition and education as main functions. The method mainly aims to stimulate scientific interest and enlighten scientific ideas by means of conventional and short-term exhibition, participation, experience and interactivity of exhibits and auxiliary exhibition means and to carry out science popularization education on the public; other science popularization education, scientific and technological transmission and scientific and cultural communication activities can be held.

The black hole is a celestial body with strong attraction and cannot escape even light. By "black" it is meant that it is like a hole in the universe, and once any material has fallen in, it "seems" to be unable to escape. According to a broad theory of relativity, when passing through a large density of celestial bodies, the space is bent, and the light is deviated from the original direction. Around the black hole, the deformation of the space is very large, one part of light can fall into the black hole and disappear, and the other part of light can bypass the black hole through the bent space and reach the earth, which is one of the reasons why the human can observe the existence of the black hole.

According to the observation of universe, there are many, if not many, black holes in the universe, and when celestial bodies in the universe or aircrafts emitted by human beings arrive near a certain black hole, if the distance and the speed of the celestial bodies or aircrafts do not reach a certain degree, the celestial bodies in the universe can be phagocytosed by the black holes, and actually, the black holes can be used for phagocytosing various celestial bodies in the universe at any time. After the aerospace technology of human beings is developed to a certain degree, the launched spacecraft can meet the threat of the black hole and how to avoid being phagocytosed by the black hole becomes a major subject to be researched by astronauts.

According to the current technical level, there are no two methods for escaping from the black hole, one is that the spacecraft has enough speed; secondly, the spacecraft is far away from the black hole as far as possible, so that the spacecraft is prevented from being phagocytized by the black hole. In the design of popular science exhibits, how to vividly and intuitively show the principle that an aircraft launched by a human is not phagocytized by a black hole and shows the principle of escaping from the black hole, the current common method is that a participant clicks and browses on a multimedia touch screen, and most browsed contents appear in a directly stated virtual animation mode, but the interactive mode of the display mode is boring, cannot actually participate or select the escaping process, lacks interestingness, is not easy to attract the participant, and is not beneficial to popular science propagation of related knowledge.

In practical applications, the interactive experience device of the present application may be arranged in a set, or may be arranged in multiple sets, such as those shown in fig. 2 to 5: the exhibition stand 6 is octagonal as a whole, and three sets of small ball launching mechanisms 2 are arranged on three adjacent surfaces of the octahedron and can be operated by three participants at the same time. Six funnel-shaped through holes are formed in the octahedral plate body to serve as a black hole plate 1, and grooves are formed in five surfaces except three adjacent surfaces provided with the small ball launching mechanisms 2 to serve as five safety grooves 3. Except that the safe groove, the small ball recovery and homing mechanism 4 is arranged below the exhibition stand 6, and other facilities are arranged on the table surface of the exhibition stand 6.

The size and the mutual distance of the black holes determine the difficulty level of the game, and after multiple times of entity simulation operation, the diameter of the black holes is 40mm, and the distance between the black holes is 200-300mm, so that the difficulty in the game process can be ensured, and the operation can be completed. The small ball is used for simulating a spacecraft launched from the earth, the launching angle and the launching speed of the small ball determine whether the small ball can bypass a black hole to reach an opposite safety groove, the small ball cannot be too heavy and too light, a certain mass and a certain volume are required, the small ball can bounce even bypass the black hole to fly if the small ball is too light, and the small ball cannot reach a certain speed if the small ball is too heavy and can fall into the black hole, so that the purpose of escaping the black hole is not realized. Through repeated experiments, the diameter of the small ball is determined to be 16mm, and the small ball is made of engineering plastics, so that the weight of the small ball is guaranteed, the quality of the small ball is guaranteed, and the purpose of repeated use can be achieved.

During the game, three participants participate in turn, each person has three balls to launch, each launching position all has a transmission signal pilot lamp, the lamp lights this participant and launches, the participant can be according to the distribution condition of black hole on the mesa, the flight direction and the flight speed of selecting launching velocity and direction and controlling the bobble through adjusting bobble launching mechanism 2 oneself, make it to walk around the black hole as far as possible, fall into opposite safety slot 3, realize escaping from the purpose of black hole, the display screen has corresponding score. For example, if the small ball falls into the safety groove 3, the ball is considered to successfully escape from the black hole, and then the score is obtained, wherein twenty minutes of each ball can be obtained, the maximum score can be 60, and if the small ball falls into the black hole, the small ball is phagocytized by the black hole and is not scored. Of course, 1-3 persons may operate independently at the same time, or more than 2 persons may compete to score more than one.

Example 2 Small ball launching mechanism 2

Referring to fig. 6 to 9, in the present application, the ball launching mechanism 2 includes a launching conduit 23 disposed horizontally, a spring ejector 22 disposed inside the launching conduit 23 at one side, a handle 21 disposed at the outer end of the spring ejector 22 and outside the launching conduit 23, and a supporting tube 24 disposed vertically at the bottom of the launching conduit 23; the launching conduit 23 is capable of rotating within a certain angular range in the horizontal plane relative to the supporting tube 24, and the launching position of the ball is arranged in front of the inner end of the spring ejection member 22.
