In this embodiment, referring to fig. 1, the spiral track is involute-shaped.
In this embodiment, referring to fig. 1, the drum has side plates 102 on both sides, which are transparent.
In this embodiment, referring to fig. 1, the outside of the side plate 102 also has a removable opaque cover plate.
In this embodiment, referring to fig. 3, the magnetic climbing device 7 includes a pulley 707 and a driving wheel 709, on which a belt 710 is sleeved, and a magnet 713 is fixedly disposed on the belt 710, where the magnet 713 attracts the iron ball and drives the iron ball to move upwards.
In this embodiment, referring to fig. 3, the lower ends of the car a and car B have baffles.
In this embodiment, the iron ball is a hollow structure, and the weight of the iron ball is adjusted by different substances filled inside.
The principles of the present invention are described below:
as shown in fig. 3, two hanger rails span the towers at both ends of the "ravines". A. And B, the two lift cars are respectively hung on the two hanging rails through pulleys and can freely slide along the hanging rails. The towers are also respectively provided with a pulley block. A cable straddles the pulley blocks at both ends and is connected with the car. The direction of movement of the two cars of A, B is reversed due to the pulley blocks. The right side of the figure is the direction of entry of the small ball, and the entry track is a three-way junction. The crossing is provided with a three-way gate, and the functions of the gate are as follows: the ball rolled from the previous link can only enter one of the intersections, and after entering, the gate is closed and the gate of the other intersection is opened. Through the ferrous ball of the three-way door and along one of the rails into the car. The front and back of the car are open, but the front end is provided with a stop block, and the small ball is stopped in the car by the stop block. Because the right tower frame is higher than the left side, the balance of the whole pulley block is destroyed after the small ball enters the car, and the car where the small ball is located moves forwards. After reaching the left end, the car collides with the rail to stop moving. While the inner ball continues to roll forward from the track due to inertia over the stop. While the other car is pulled back to the right, waiting for the next ball … … to push in this manner, and so on.
Referring to fig. 4, this structure uses the principle of elastic collision. As shown in fig. 4, a plurality of iron balls, such as A, B, C, are arranged on the downhill track, and are stationary due to the small stop blocks. The ball D rolled at a certain speed from the previous step collides with the ball C elastically, and energy is exchanged, and the energy is transferred to the ball a through the ball B. Because the balls are of equal mass, ball a then attains a speed equal to ball D, and impacts the stop. While pellet D loses energy at zero velocity as pellet C, B. But because they are on a slope, they are stationary only briefly and eventually roll together slowly to the stop position. Due to the smaller energy, it is eventually stopped by the stop, stopping until the ball a hits the ball D after a cycle. This situation is much like queuing waiting vehicles.
Referring to fig. 1, the left and right sides of the drum are two organic glass discs with a circular hole in the middle. A long plastic sheet bent into a spiral shape connects the two wafers together. Referring to fig. 1, a ball is placed on a spiral track in a central hole 101, and when the gradient is proper, the ball drives a roller to roll upwards along the slope. This is because the height of the iron balls is continuously lowered during the forward rolling of the drum. Although the position of the drum is increasing, the center of gravity of the system of drum and iron balls is decreasing due to the relatively heavy iron balls. That is, the gravitational potential energy of the object system is decreasing during the ascending of the drum. According to the energy principle in mechanics, the object has a tendency to change from a high-energy state to a low-energy state, so that the roller with the iron balls can roll upwards along a slope.
The magnetic climbing device is shown in fig. 3, and a belt conveyer is arranged below a section of inclined plane. The belt conveying device consists of a driving wheel, a belt pulley, a belt and a motor unit, and the belt continuously runs in the direction shown in the figure under the driving of the motor unit. A small magnet is fixed outside the belt. The magnet is driven by the belt to periodically pass through the lower part of the inclined plane. As shown in the figure, the iron ball rolls from the previous link along the downhill track and stops at the lowest point. When the magnets on the belt pass through the belt, the balls roll upwards along the inclined plane under the attraction of the magnets. When the ball rolls over the highest point, the magnet turns down the pulley, at which point the ball loses attraction and continues to roll forward along the return track on a slight downhill slope.
Each link in the device comprises a typical physical principle, so that the device is also suitable for demonstration teaching in physical classes. And the school bus can be provided with a physical special lecture for extracurricular activities. In addition, the device can automatically and circularly demonstrate and can be set in an attempt
Embodiment two:
the difference from the first embodiment is that: the side plates at two sides of the roller are made of materials with adjustable transparency.
According to the invention, the energy storage lifting section lifts the energy storage, and the energy release section releases the energy in a falling way, so that the energy storage lifting section can always reciprocate without stopping; the physical principles such as conversion between potential energy and kinetic energy can be better represented in a fun way, and the effect of automatic teaching demonstration is better; the curiosity of people is easy to be aroused, and the people are taught in the lively activities; the design of the roller and the spiral track inside the roller is ingenious, and the transparent side plate and the opaque cover plate are arranged on the roller, so that the teaching demonstration effect is improved; the structure is simple, and the design of the car is ingenious; by utilizing the inertia of the iron spheres, the iron spheres are set to have equal mass, so that the function of queuing in sequence is realized, and the design is ingenious.
The foregoing is a preferred embodiment of the present invention, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed invention.
