Description

Technical Field

[0001] This invention relates to the field of Coriolis inertial force experimental equipment, and in particular to a rotating base for Coriolis inertial force experiments. Background Technology

[0002] Coriolis inertial force is a virtual force experienced by an object when it moves in a rotating reference frame. Its principle is abstract and difficult to demonstrate intuitively, so experimental setups play an important role in teaching and scientific research.

[0003] In existing technologies, traditional equipment often relies on manual rotation speed adjustment, resulting in poor speed stability and low precision, making it difficult to accurately measure the magnitude of the Coriolis force under different rotational conditions. Adjusting the level of the rotating platform depends on simple tools such as shims, which is cumbersome and lacks precision, easily introducing additional errors due to tilting and affecting the accuracy of experimental data. Furthermore, the equipment is difficult to move, mostly fixed to the experimental platform, and cannot flexibly adapt to the needs of different teaching or research scenarios. These problems make existing equipment unable to meet the requirements of high-precision, multi-condition Coriolis inertial force experiments, hindering in-depth research on the principles of Coriolis force and the effectiveness of practical teaching.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figures 1-3 The present invention provides a rotating base for Coriolis inertial force experiments, comprising:

[0041] Base 1, with several lifting leg assemblies installed at the bottom of base 1, and pulley assemblies installed at the fixed ends of the lifting leg assemblies; base 1 has a triangular structure with a diameter of 1500mm;

[0042] The column assembly is mounted on the base 1;

[0043] Slewing support 2 is rotatably connected to the top of the column assembly;

[0044] Top plate 3 is fixedly installed on slewing support 2. Top plate 3 is used to install Coriolis inertial force testing module; in this embodiment, the size of top plate 3 is 350mm*300mm*30mm.

[0045] The drive mechanism is mounted on the column assembly and is used to drive the slewing bearing 2 to rotate.

[0046] The control system is mounted on the base 1, and the drive mechanism is electrically connected to the control system.

[0047] With this configuration, the present invention achieves a rotatable connection between the column assembly and the top plate 3 through the rotary support 2. Combined with the stable output of the drive mechanism, it can ensure that the top plate 3 runs smoothly during rotation, reduce shaking or jamming, achieve stable rotation of the Coriolis inertial force testing module, meet the experimental requirements under different rotational angular velocities, and greatly improve the reliability of experimental data.

[0048] The invention features a height-adjustable lifting leg assembly that allows for quick calibration of the top plate's level, avoiding additional errors caused by platform tilt and simplifying the pre-experiment debugging process. The pulley assembly at the bottom of the lifting leg assembly enables the equipment to be moved easily, breaking the limitations of fixed installation in traditional equipment. It allows for flexible switching of experimental sites according to teaching or research needs, improving the equipment's versatility and ease of operation.

[0049] This invention achieves automated experimental operation by controlling the start, stop and speed of the drive mechanism through the control system, reducing errors caused by manual intervention and improving experimental efficiency; the top plate 3 serves as the mounting carrier for the Coriolis inertial force testing module, and its structural design is universal, adaptable to different types of testing modules, and meets diverse Coriolis inertial force experimental needs.

[0050] The scheme has been further optimized, and the drive mechanism includes:

[0051] The drive assembly is mounted on the column assembly and is electrically connected to the control system.

[0052] Drive gear 4 is mounted on the output shaft of the drive assembly;

[0053] Gear ring 5 is fixedly installed on the outer wall of the rotary support 2, and gear ring 5 meshes with drive gear 4 for transmission.

[0054] The scheme is further optimized. The drive component includes a drive motor 6 that is electrically connected to the control system. The drive motor 6 is mounted on the column assembly via a motor mount, and the drive gear 4 is mounted on the output shaft of the drive motor 6.

[0055] The control system starts the drive motor 6, which in turn drives the drive gear 4 to rotate. The drive gear 4, through meshing with the gear ring 5, transmits power to the slewing support 2, causing it to rotate around the top of the column assembly. This, in turn, drives the top plate 3 and the Coriolis inertia force testing module to rotate synchronously. This gear meshing transmission method ensures the stability and precision of power transmission, allowing for precise control of the slewing support 2's rotational speed according to changes in the drive assembly's output. The drive motor 6 provides a stable torque output, and with the pulse signal control of the control system, it enables stepless speed adjustment, meeting the precise requirements of different experiments for rotational angular velocity and providing stable and controllable rotational power for the experiments.

[0056] The design has been further optimized, and the lifting outrigger assembly includes:

[0057] Connecting seat 7 is fixedly installed on the bottom of base 1;

[0058] Sleeve 8 is rotatably connected to connecting seat 7. The bottom of sleeve 8 is open, and an operation window 9 is opened on the side wall of sleeve 8. The pulley assembly is fixedly installed on the outer side wall of sleeve 8.

[0059] The outrigger body 10 is slidably connected to the inner wall of the sleeve 8.

[0060] Screw 11, the top of screw 11 is rotatably connected to connecting seat 7, and the bottom is threadedly connected to support leg body 10;

[0061] The handle 12 is fixedly installed on the outer wall of the screw 11;

[0062] During adjustment, the handle 12 is rotated through the operation window 9, causing the screw 11 to rotate. The screw 11 engages with the threaded connection between itself and the support leg body 10, allowing the support leg body 10 to slide up and down along the sleeve 8, thus adjusting the height of the base 1. When moving the equipment, the support leg body 10 moves upward so that the pulley assembly contacts the ground; when fixing, the support leg body 10 moves downward until it contacts the ground, suspending the pulley assembly in the air to ensure equipment stability. This structure achieves fine-tuning of height through threaded transmission, ensuring accurate level calibration of the top plate 3.

[0063] The design is further optimized by including a cover 13 fixedly mounted on the outer wall of the sleeve 8, with a traveling wheel 14 rotatably connected to the bottom of the cover 13. The cover 13 protects the traveling wheel 14, preventing debris from getting tangled and affecting its rotation. When the lifting leg assembly is adjusted so that the traveling wheel 14 contacts the ground, pushing the base 1 allows the entire device to move via the rolling of the traveling wheel 14, reducing the difficulty of movement, enabling the device to flexibly switch experimental sites, and improving ease of use.

[0064] The scheme is further optimized. The column assembly includes a column body 15 and a slewing support fixing flange plate 16. The bottom of the column body 15 is fixedly installed on the base 1, and the slewing support fixing flange plate 16 is fixedly installed on the top of the column body 15. The drive motor 6 is installed on the slewing support fixing flange plate 16 through a motor mount, and the slewing support 2 is rotatably connected to the slewing support fixing flange plate 16.

[0065] The design is further optimized so that there are three wheels 14 and three outriggers 10. The triangular distribution provides stability, and the three outriggers 10 ensure that the base 1 is placed stably and avoids shaking. When the three wheels 14 are in contact with the ground, the equipment is not easy to tip over during movement. This design balances the flexibility of equipment movement with the stability of placement, and adapts to the usage needs of different ground environments.

[0066] In a further optimized design, the length of the slewing support fixing flange plate 16 is 300mm to 500mm, preferably 420mm in this embodiment; the width of the slewing support fixing flange plate 16 is 200mm to 400mm, preferably 300mm in this embodiment; and the length of the slewing support fixing flange plate 16 is 20mm to 40mm, preferably 30mm in this embodiment.

[0067] Further optimization of the design: the column body 15 is hollow inside, and the length of the column body 15 is 400mm to 600mm, preferably 505mm in this embodiment; the hollow structure reduces the weight of the column body 15, reduces the load-bearing pressure on the base 1, and facilitates internal wiring, making the equipment layout neater.
