Description

Technical Field

[0001] This invention belongs to the technical field of gravity experiment simulation equipment, and specifically relates to a physical gravity experiment simulation platform for teaching demonstration. Background Technology

[0002] Projectile motion is the most common gravity experiment in teaching demonstrations. However, due to the high speed of projectile motion, students find it difficult to accurately understand the actual projectile process, and they are even less able to use this information for subsequent analysis and calculation. Therefore, a simulation platform is needed to accurately analyze and record the projectile process, thereby ensuring the effectiveness of the teaching demonstration. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a physical gravity experiment simulation platform for teaching demonstrations, thereby resolving the issues raised in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a physical gravity experiment simulation platform for teaching demonstration, comprising a horizontal indicator plate and a vertical indicator plate. Two sets of vertical rods are connected to the side of the horizontal indicator plate away from the vertical indicator plate. Each vertical rod is slidably connected to a first sliding sleeve. A first horizontal plate is connected between the two sets of first sliding sleeves. A first high-speed camera is mounted in the middle of the first horizontal plate, facing the vertical indicator plate. Horizontal rods are connected to both sides of the top of the vertical indicator plate. The two sets of horizontal rods are connected to the vertical rods via a crossbar. Second sliding sleeves are slidably connected to each horizontal rod. A second horizontal plate is connected between the two sets of second sliding sleeves. A second high-speed camera is mounted on the second horizontal plate, facing the horizontal indicator plate. A slider is slidably connected to each horizontal rod. Two sets of auxiliary rods are connected below the slider. Sleeves are slidably connected to each set of auxiliary rods. A support cylinder is hinged between the two sets of sleeves. A shot blasting mechanism for blasting metal shot is installed inside the support cylinder.

[0005] By adopting the above technical solution, in actual use, the shot blasting mechanism can shoot out metal balls, which can be recorded by the first high-speed camera, thus facilitating the understanding of the trajectory of the oblique projectile motion of the metal balls and providing assistance for subsequent calculation and analysis; the shooting and recording by the second high-speed camera can record the trajectory of the metal balls in the horizontal direction, which also provides assistance for subsequent analysis and calculation.

[0006] Preferably, an inclined guide plate is provided above the horizontal indicator plate, and the guide plate is inclined toward the shot blasting mechanism.

[0007] By adopting the above technical solution, the guide plate can simulate the movement of a slope during use, and the second high-speed camera can capture and record the data, which is convenient for subsequent analysis.

[0008] Preferably, a support plate is installed at the lower part of the horizontal indicator plate, the support plate is provided with an inclined groove with the opening facing upward, and the horizontal indicator plate is provided with an opening corresponding to the inclined groove.

[0009] By adopting the above technical solution, when the metal pellets are released, they will hit the guide plate and move into the inclined groove through the guide plate, thus facilitating the collection of the metal pellets.

[0010] Preferably, the shot blasting mechanism includes a square cylinder connected to the inner wall of a support cylinder. A first sliding plug is slidably connected inside the square cylinder. One side of the first sliding plug is connected to an insert plate. An externally threaded tube is slidably connected to the outer side of the insert plate. A rotating plate is rotatably connected to the end of the square cylinder away from the first sliding plug. The externally threaded tube passes through the rotating plate and is threadedly connected to the rotating plate. A handle is connected to the side of the rotating plate. A spring is provided between the first sliding plug and the rotating plate. One end of the spring is connected to the first sliding plug, and the other end of the spring is fixedly connected to the inner wall of the square cylinder. A movable pin is movably connected to one side of the externally threaded tube. The movable pin passes through the insert plate and locks the insert plate.

[0011] By adopting the above technical solution, during use, the external threaded tube can be moved by turning the handle, thereby pulling the first piston plate to move and compress the spring. After removing the movable pin, it can be unlocked. Driven by the spring, the first piston plate moves quickly to impact the metal shot located in the square cylinder, thus realizing the shot blasting operation.

[0012] Preferably, a guide tube is provided above the horizontal indicator plate, the lower side of the guide tube is connected to the inclined groove, the upper part of the guide tube is connected to an inclined material guide tube, one side of the square cylinder is connected to the lower end of the material guide tube through a material guide hose, the material guide hose passes through the slider, and a first magnet corresponding to one end of the material guide hose is installed on the inner side of the square cylinder.

[0013] A vertical transport tube is connected to the side of the guide tube. A third sliding plug is slidably connected inside the transport tube. A second magnet is connected to the upper part of the third sliding plug. A sliding cavity is provided on the inner side of the support plate. The sliding cavity is connected to the lower end of the transport tube. A second sliding plug is installed inside the sliding cavity. A hydraulic telescopic rod is connected to the side of the second sliding plug away from the transport tube.

[0014] The side wall of the square cylinder is connected to a liquid guide tube. Liquid is stored between the first sliding plug and the rotating plate. The liquid guide tube is connected to the liquid. Liquid is filled between the second sliding plug and the third sliding plug.

[0015] By adopting the above technical solution, when the handle is turned to move the first sliding plug, the liquid on one side of the first sliding plug is compressed, causing the liquid to enter the hydraulic telescopic rod in the sliding cavity. The extension of the first hydraulic telescopic rod pushes the second sliding plug to move, thereby squeezing the liquid in the sliding cavity into the transport pipe. As a result, the third sliding plug in the transport pipe moves upward, driving the second magnet upward. The second magnet in the transport pipe attracts the metal shot located at the bottom of the guide tube. Under the attraction and movement of the second magnet, the metal shot rolls upward in the guide tube. After the metal shot moves to the top of the guide tube, the second magnet and the metal shot detach from the attraction. The metal shot then re-enters the shot blasting mechanism through the guide tube and guide hose, facilitating subsequent shot blasting operations. The first magnet is positioned to stabilize the metal shot after it enters the square cylinder, preventing it from falling out of the square cylinder.

[0016] Preferably, the inner side of the guide tube is provided with an inclined baffle, the lower end of the baffle is hinged to the inner wall of the guide tube, and the lower end of the baffle corresponds to the upper end of the guide tube.

[0017] By adopting the above technical solution, after the metal shot moves upward through the guide tube and passes the baffle, the baffle can automatically fall back by gravity, and the metal shot will not fall back to the bottom of the guide tube. At the same time, the metal shot can also easily roll through the baffle into the feed tube, and then into the feed hose and into the shot blasting mechanism.

[0018] Preferably, the inner wall of the guide tube is provided with cleaning bristles.

[0019] By adopting the above technical solution, when the metal pellets in the guide tube are attracted by the second magnet and roll upward, the cleaning bristles are used to clean the metal pellets.

[0020] Preferably, the support cylinder is connected to the sleeve via a damping shaft.

[0021] By adopting the above technical solution, the support cylinder can be easily adjusted at a specific angle, thereby controlling the shot blasting direction of the shot blasting mechanism.

[0022] Preferably, the lower end of the guide plate is hinged to the horizontal indicator plate via a damping hinge.

[0023] By adopting the above technical solution, the guide plate can be easily adjusted to a specific angle to meet actual usage requirements and facilitate the simulation of slope movement.

[0024] Preferably, the transport tube is transparent and has scale lines on its outer surface.

[0025] By adopting the above scheme, the movement position of the third sliding plug inside the transport pipe can be observed intuitively, and the compression of the spring can be quickly understood, thereby better controlling the shot blasting force of the shot blasting mechanism.

[0026] The technical effects and advantages of this invention are as follows:

[0027] This invention uses a shot blasting mechanism to launch metal balls, which can be recorded by a first high-speed camera to facilitate understanding of the trajectory of the metal balls' oblique projectile motion, thus aiding in subsequent calculations and analyses. The second high-speed camera can also record the trajectory of the metal balls in the horizontal direction, further assisting in subsequent analysis and calculations.

[0028] 2. This invention can move the external threaded tube by turning the handle, thereby pulling the first piston plate to move and compress the spring. It can be unlocked after removing the movable pin. Driven by the spring, the first piston plate moves quickly to impact the metal shot located in the square cylinder, thus realizing the shot blasting operation.

[0029] 3. When the handle is turned and the first sliding plug is moved, the liquid on one side of the first sliding plug is compressed, causing the liquid to enter the hydraulic telescopic rod in the sliding cavity. The extension of the first hydraulic telescopic rod pushes the second sliding plug to move, thereby squeezing the liquid in the sliding cavity into the transport pipe. As a result, the third sliding plug in the transport pipe moves upward, and drives the second magnet to move upward. The second magnet in the transport pipe attracts the metal shot located at the bottom of the guide tube. Under the attraction and movement of the second magnet, the metal shot rolls upward in the guide tube. After the metal shot moves to the top of the guide tube, the second magnet and the metal shot detach from the attraction. The metal shot will then enter the shot blasting mechanism again through the guide tube and guide hose, thus facilitating subsequent shot blasting operations.

[0030] 4. After the metal shot moves upward through the guide tube and passes the baffle, the baffle can automatically fall back by gravity, and the metal shot will not fall back to the bottom of the guide tube. At the same time, the metal shot can easily roll through the baffle into the feed tube, and then into the feed hose and into the shot blasting mechanism.

[0031] 5. As the metal pellets inside the guide tube are attracted by the second magnet and roll upwards, the cleaning bristles are used to clean the metal pellets.

[0032] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

[0045] When in use, the metal pellets will hit the guide plate 16 after being ejected, and then move into the inclined groove 18 through the guide plate 16, thus facilitating the collection of the metal pellets.

[0046] As one embodiment of the present invention, such as Figure 1 , 2As shown, the present invention also includes the shot blasting mechanism 15 comprising a square cylinder 20, the square cylinder 20 being connected to the inner wall of the support cylinder 19, a first sliding plug 21 being slidably connected inside the square cylinder 20, an insert plate 22 being connected to one side of the first sliding plug 21, an external threaded tube 23 being slidably connected to the outer side of the insert plate 22, a rotating plate 24 being rotatably connected to one end of the square cylinder 20 away from the first sliding plug 21, the external threaded tube 23 passing through the rotating plate 24 and being threadedly connected to the rotating plate 24, a handle 25 being connected to the side of the rotating plate 24; a spring 26 being provided between the first sliding plug 21 and the rotating plate 24, one end of the spring 26 being connected to the first sliding plug 21, the other end of the spring 26 being fixedly connected to the inner wall of the square cylinder 20, a movable pin 27 being movably connected to one side of the external threaded tube 23, the movable pin 27 passing through the insert plate 22 to lock the insert plate 22.

[0047] In use, the external threaded tube 23 can be moved by turning the handle 25, thereby pulling the first piston plate to move and compress the spring 26. It can be unlocked after removing the movable pin 27. Driven by the spring 26, the first piston plate moves quickly to impact the metal shot located in the square tube 20, thus realizing the shot blasting operation.

[0048] As one embodiment of the present invention, such as Figure 1 , 2 As shown in Figures 3 and 4, the present invention also includes a guide tube 28 above the horizontal indicator plate 1. The lower side of the guide tube 28 is connected to the inclined groove 18. The upper part of the guide tube 28 is connected to an inclined guide tube 29. One side of the square cylinder 20 is connected to the lower end of the guide tube 29 through a guide hose 30. The guide hose 30 passes through the slider 12. A first magnet 31 corresponding to one end of the guide hose 30 is installed on the inner side of the square cylinder 20.

[0049] A vertical transport pipe 39 is connected to the side of the guide tube 28. A third sliding plug 36 is slidably connected inside the transport pipe 39.

The liquid guide tube 38 is in communication with the liquid. Liquid is filled between the second sliding plug 34 and the third sliding plug 36.

[0051] During use, when the handle 25 is turned to move the first sliding plug 21, the liquid on one side of the first sliding plug 21 is compressed, causing the liquid to enter the hydraulic telescopic rod 35 in the sliding cavity 33. The extension of the first hydraulic telescopic rod 35 pushes the second sliding plug 34 to move, thereby squeezing the liquid in the sliding cavity 33 into the transport pipe 39. As a result, the third sliding plug 36 in the transport pipe 39 moves upward, driving the second magnet 37 to move upward. The second magnet 37 in the transport pipe 39 attracts the metal shot located at the bottom of the guide pipe 28. Under the attraction and movement of the second magnet 37, the metal shot rolls upward in the guide pipe 28.

[0053] During use, after the metal shot moves upward through the guide tube 28 and passes the baffle 32, the baffle 32 can automatically fall back by gravity, and the metal shot will not fall back to the bottom of the guide tube 28. At the same time, the metal shot can easily roll through the baffle 32 into the feed tube 29, and then into the feed hose 30 and into the shot blasting mechanism 15.

[0054] As an embodiment of the present invention, as shown in the figure, the present invention also includes cleaning bristles on the inner wall of the guide tube 28.

[0055] During use, as the metal pellets inside the guide tube 28 are attracted by the second magnet 37 and roll upwards, the cleaning bristles are used to clean the metal pellets.

[0056] As one embodiment of the present invention, as shown in the figure, the present invention also includes the support cylinder 19 being connected to the sleeve 14 via a damping shaft.

[0057] During use, the support cylinder 19 can be easily adjusted to a specific angle, thereby controlling the shot blasting direction of the shot blasting mechanism 15.

[0058] As an embodiment of the present invention, the present invention further includes the lower end of the guide plate 16 being hinged to the horizontal indicator plate 1 via a damping hinge.

[0059] During use, the guide plate 16 can be easily adjusted to a specific angle to meet actual usage requirements and facilitate the simulation of slope movement.
