Technical Field
[0001] This utility model relates to the field of auxiliary equipment for physical experiments, specifically an intelligent projectile motion experimental device. Background Technology
[0002] Projectile motion refers to the motion of a projectile thrown horizontally with a certain initial velocity. It can be regarded as the combined motion of uniform linear motion in the horizontal direction and free fall in the vertical direction. In order to improve the accuracy of observation and recording of the trajectory and landing point of projectile motion, multiple projectile experiments need to be conducted in the same environment.
[0003] In current projectile motion experiments, it is still necessary to manually measure the flight time and landing distance of the projectile, and operators need to read and record the data in real time. In practice, this can easily lead to large experimental errors and low efficiency.
[0004] To address the aforementioned issues, we have made improvements and proposed an intelligent projectile motion experimental device. Utility Model Content

[0012] The beneficial effects of this invention are as follows: This intelligent projectile motion experimental device uses a movable projectile track, a data acquisition unit, and scale lines to conduct experiments on projectile data at different heights.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0018] Example: Figure 1-2As shown, an intelligent projectile motion experimental device includes a base 1, a projectile track 4, and a projectile 6. A fixed rod 2 is connected to the upper part of the base 1. The projectile track 4 is located outside the fixed rod 2. A photoelectric gate sensor 5 is provided at the bottom of the projectile track 4. A horizontal frame 3 is installed on the side of the base 1. A data acquisition device 7 is slidably installed on the horizontal frame 3. A contact sensor is installed inside the data acquisition device 7.
[0019] The fixed rod 2 and the horizontal frame 3 are respectively fixedly connected to the base 1 by bolts. The two sides of the horizontal frame 3 are respectively provided with slide rails 13. The bottom of the data acquisition device 7 is fixedly installed with a connector 15. The distance between the data acquisition device 7 and the fixed rod 2 is adjusted according to the different heights of the projectile track 4 so that the projectile 6 can fall onto the data acquisition device 7 after the projectile motion.
[0020] A knob 16 is threaded onto the outer surface of the connector 15, and a slider 17 is provided on the inner surface of the connector 15. The knob 16 and the slider 17 are coaxially fixedly connected, and the slider 17 is slidably connected to the inner surface of the slide rail 13. The slider 17 is in contact with the inner surface of the slide rail 13. The slider 17 remains stable when the knob 16 is rotated. When it is necessary to move the data acquisition device 7, the knob 16 is turned to increase the distance between the two sliders 17. After adjusting the data acquisition device 7 to the required position, the knob 16 is turned in the opposite direction to make the slider 17 fit tightly against the inner side of the slide rail 13, thus maintaining the stability of the data acquisition device 7 during the experiment.
[0021] A side guard 12 is installed on the upper edge of the data acquisition unit 7. A rubber pad 8 is installed on the top of the data acquisition unit 7. The contact sensor is located below the rubber pad 8. A high-performance lithium battery and a Bluetooth module are installed inside the data acquisition unit 7. A display screen 9 for operation and digital display is installed on the side of the data acquisition unit 7. The display screen 9 is a 2.3-inch TFT display screen. After the projectile 6 is launched from the end of the projectile track 4, it falls onto the upper part of the data acquisition unit 7. The contact sensor under the rubber pad 8 collects the landing point data and displays it on the display screen 9. The data acquisition unit uses a USB Type-C data cable to connect to a computer to transmit data. At the same time, the Bluetooth module transmits the data to an external computer for collection and analysis. The horizontal displacement and fall time of the projectile 6 during the projectile motion are calculated and statistically analyzed in conjunction with the data recorded by the photoelectric gate sensor 5.
[0022] The outer surface of the projectile track 4 is slidably connected to the outer surface of the fixed rod 2, and the inner surface of the projectile track 4 is equipped with bolts for limiting movement. The photoelectric door sensor 5 is fixedly connected to the projectile track 4. The projectile 6 is placed inside the projectile track 4. When the projectile 6 is placed on the top of the projectile track 4, the projectile 6 will slide off the projectile track 4 under the action of gravity.
[0023] The side surfaces of the fixed rod 2 and the horizontal frame 3 are provided with scale lines 11. The bottom of the base 1 and the horizontal frame 3 are respectively fixedly connected to the stabilizing frame 10, and the bottom of the stabilizing frame 10 is threadedly connected to several adjusting feet 14.
[0024] Working principle: In use, the projectile 6 is placed on top of the projectile track 4. The projectile 6 will slide off the projectile track 4 under the action of gravity. The distance between the data acquisition device 7 and the fixed rod 2 is adjusted according to the height of the projectile track 4 so that the projectile 6 can land on the data acquisition device 7 after the projectile motion. After being thrown from the end of the projectile track 4, the projectile 6 lands on the top of the data acquisition device 7. The contact sensor under the rubber pad 8 collects the landing point data and displays it on the display screen 9. The data acquisition device is connected to a computer via a USB Type-C data cable to transmit data. At the same time, the Bluetooth module transmits the data to an external computer for collection and analysis. The data recorded by the photoelectric gate sensor 5 is used to calculate and statistically analyze the horizontal displacement and fall time of the projectile 6 during the projectile motion.
