Technical Field
[0001] This utility model relates to the field of physical principle demonstration and popular science, specifically to a comprehensive demonstration device of the steepest curve and Archimedes' spiral principle. Background Technology
[0002] Science popularization is a fundamental project for the development of national science and technology, bearing the important mission of cultivating an environment conducive to innovation, strengthening the foundation of talent, and building social consensus. The methods of science popularization are constantly innovating with the times. From traditional science books, lectures, and documentaries to offline science exhibitions and science education training, diversified channels are building an ecosystem of "comprehensive science popularization." Among these, physical science installations, as concrete and experiential carriers of science popularization, have irreplaceable value.
[0003] Currently, the construction of basic education facilities in my country is booming, but science education installations targeting physics and chemistry have not received much attention. A major reason for this is the relatively lagging development of outdoor science installations themselves; there are no readily available products, preventing them from entering the construction phase. Therefore, developing outdoor physics-related science installations is of great significance for improving the public's physics knowledge and strengthening science education. Utility Model Content
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A comprehensive demonstration device integrating the principles of the brachistochrone curve and the Archimedes' spiral includes a support body, a curve feature channel, an Archimedes' spiral device, a lower guide groove, a lower collection cavity, a demonstration ball, and a transparent shell. The supporting body shown has a reset guide groove and a stable support body. One end of the curved feature channel is supported on the supporting body and communicates with the reset guide groove, while the other end communicates with the lower guide groove. The lower guide groove and the lower collection cavity are both installed at the bottom of the device and are interconnected. The Archimedes' spiral device has an upper opening and a lower opening. One end of the Archimedes' spiral device is supported on the supporting body. The supporting body also has an upper collection cavity and a stable support body. The upper opening of the Archimedes' spiral device is located above the upper collection cavity, and the upper collection cavity communicates with the reset guide groove. One end of the Archimedes' spiral device is located at the lower collection cavity, and the lower opening of the Archimedes' spiral device communicates with the collection cavity. The reset guide groove and the lower guide groove are inclined, and the upper collection cavity and the lower collection cavity have an inclination or slope. The number of curved feature channels is one or more, wherein the trajectory of at least one curved feature channel conforms to the steepest curve.
[0006] Optional features include multiple curve feature channels. Specifically, three curve feature channels can be set, including convex curve, straight line, and concave curve.
[0007] Preferably, it also includes a small ball baffle, which is disposed at the entrance of the curved feature channel.
[0008] Preferably, a small ball baffle is provided at the entrance of each curve feature channel, and each small ball baffle performs an action through a baffle actuation component.
[0009] It also includes a reset guide groove isolation plate, which is disposed on the reset guide groove.
[0010] Optionally, one or more demo balls can be set.
[0011] Optionally, the baffle actuator can be a linkage mechanism or other linkage mechanism. By operating the baffle actuator, the opening or closing action of the small ball baffle corresponding to each curve feature channel can be realized.
[0012] The reset guide groove is inclined to one side of the curved feature channel; the upper collection cavity has an inclination that causes the demonstration ball to roll toward the reset guide groove; the lower guide groove is inclined to one side of the lower collection cavity.
[0013] Optionally, the reset guide groove can be any guide groove with an angle.
[0014] The lower guide groove causes the demonstration ball to roll towards the lower collection cavity, towards the side of the lower opening of the Archimedes' screw device. After rolling out of the curved feature channel outlet, the demonstration ball rolls along the lower guide groove towards the lower collection cavity until it reaches the lower opening of the Archimedes' screw device. By rotating the operating handle of the Archimedes' screw device, the demonstration ball at the lower opening of the Archimedes' screw device is moved upwards, exiting through the upper opening of the Archimedes' screw device into the upper collection cavity, rolling to the reset guide groove, and then rolling to the entrance of the curved feature channel, ready for the next demonstration.
[0015] Preferably, the main body of the Archimedes screw device is supported by a stable support body, which can improve the stability of the device; the operating handle of the Archimedes screw device can be set separately or as a whole.
[0016] By setting up a stable support structure, the overall volume of the support body is reduced while the stability of the device is improved.
[0017] When the operating handles of the Archimedes screw device are set separately, the operation of each Archimedes screw device can be controlled independently, and multiple people can operate each Archimedes screw device simultaneously, increasing the participation of multiple people in the demonstration device.
[0018] When set up as a single unit, each Archimedean spiral can be controlled to rotate together. This allows for simultaneous operation by a single person, controlling multiple Archimedean spirals to reset the demonstration ball. Specifically, a gear transmission system is used, where one gear drives multiple gears fixed to each Archimedean spiral.
[0019] Preferably, it also includes an automatic photo and video recording module, including a camera, display screen, sensing system, shooting system, and storage system.
[0020] Optionally, the demonstrator can activate the automatic photo and video recording module by registering as a user. Sensors are installed on the ball baffle and the upper collection chamber. When the ball baffle is detected to be open, the photo and video recording module is activated to automatically record the experiment. When the demonstration ball falls onto the upper collection chamber, the recording system stops operating, and the recorded demonstration video is automatically stored in the storage system. The demonstrator can download the demonstration video to their own portable terminal device.
[0021] Preferably, it also includes a module for demonstrating the principles, including a display screen and an operating system.
[0022] Optionally, the demonstration principle explanation module stores videos explaining the brachistochrone curve and the Archimedes' spiral principle. Demonstrators can choose to watch the principle explanation videos before or after the demonstration to gain a deeper understanding of the brachistochrone curve and the Archimedes' spiral principle in conjunction with the demonstration process.
[0023] Optionally, the demonstrator can also call the automatic photo and video recording module to record their understanding of the brachistochrone curve and the Archimedes' spiral principle, and store it in the demonstration principle explanation module for other demonstrators to refer to, thus enhancing the interactivity of the demonstration device.
[0024] The beneficial effects of this invention are as follows: The integrated demonstration device for the brachistochrone curve and Archimedean spiral principle is simple to operate and can comprehensively demonstrate the brachistochrone curve and Archimedean spiral principle, simultaneously displaying the brachistochrone curve of multiple curve feature channels. This invention cleverly combines the demonstration of the brachistochrone curve and Archimedean spiral principle, using an Archimedean spiral device to reset the demonstration ball upwards, thus solving the problem of ball reset while demonstrating the Archimedean spiral principle. Utilizing the inclined surface, after the ball is moved by the Archimedean spiral device, it can return to the initial position of the brachistochrone curve demonstration. This invention can achieve cyclical demonstrations of the brachistochrone curve and Archimedean spiral principle, is reusable, and has strong practicality. Attached Figure Description
