Description

Technical Field

[0001] The invention belongs to the field of electrical and electronic technology, and specifically relates to an electrical and electronic training platform for school students. Background Art

[0002] Electronic and electrical engineering technology is an engineering technology that studies the generation, transmission, conversion, control, detection and application of electric energy, including analysis methods of DC circuits and AC circuits, such as Ohm's law and Kirchhoff's law. This is the foundation of electrical engineering technology, used to analyze and solve various problems in circuits, involving the working principle, structure, performance of various motors (such as DC motors, asynchronous motors, etc.) and the principle and application of transformers. Motors are important equipment for converting electrical energy into mechanical energy and are widely used in industrial production and daily life. They cover power generation, transmission, distribution and power consumption, including the planning, design, operation and management of power systems. Power systems are important infrastructure for the normal operation of modern society, including the use of electrical control components such as relays, contactors, PLCs and the design of control systems, which are used to realize the automatic control of production equipment and process flows. The electrical and electronic training platform is a student training platform that can train students on basic electronic and electrical skills, basic motor control circuit installation, debugging and maintenance, and through basic operating skills and circuit production and debugging, enable students to master the production and debugging of electronic products, be familiar with the selection and testing of commonly used electronic devices, and master circuit assembly process skills.

[0003] Chinese patent document CN214955582U discloses a training platform for electrical and electronic teaching, including a workbench, a support block is fixedly installed on the top of the left end of the workbench, a receiving plate is fixedly installed on the top of the right end of the workbench, a cross bar is fixedly connected to the right side of the rear end of the support block, a slider is movably connected to the outside of the cross bar, a connecting plate is fixedly connected to the front of the slider, and a hook plate is placed on the upper end of the support block.

A first training panel 3 and a second training panel 4 are provided in parallel above the drive box 2, and a training module 5 is provided on each of the first training panel 3 and the second training panel 4.

[0028] The first training panel 3 and the second training panel 4 can be set with different training modules 5 according to actual needs, wherein the training module 5 includes a power module, a button indicator module, a hanging box module, an electrical module and a peripheral installation module. The training module 5 is mainly used for power supply and automation control equipment, actuators and practical applications of electrical engineering. The purpose is to enhance students' understanding and mastery of automation and electrical engineering, strengthen hands-on operation ability, combine theory with practice, eliminate the disconnection between modern industry and theoretical knowledge, and cultivate students' professional and technical capabilities in equipment cognition, system combination design, automation control, equipment installation and wiring, parameter setting and debugging, combination circuit control, operation and maintenance, etc. The first training panel 3 and the second training panel 4 can be raised and lowered. When the first training panel 3 rises to the top of the training platform 1, the second training panel 4 descends and hides under the training platform 1; when the second training panel 4 rises to the top of the training platform 1, the first training panel 3 descends and hides under the training platform 1, so that the training platform 1 can conveniently display the training module 5 required for demonstration.

[0029] like Figure 6 As shown, a first opening 6 and a second opening 7 are provided on the top surface of the driving box 2, and a U-shaped rigid chain 8 is provided inside the driving box 2. One end of the rigid chain 8 passes through the first opening 6 and is connected to the first training panel 3, and the other end of the rigid chain 8 passes through the second opening 7 and is connected to the second training panel 4. The rigid chain 8 is equipped with a driving mechanism, and the driving mechanism is used to drive the rigid chain 8 to reciprocate so that the first training panel 3 and the second training panel 4 can be lifted and lowered in opposite directions. The rigid chain 8 has a first end and a second end, and the first end is provided with a first joint 22, and the second end is provided with a second joint 23. The first end of the rigid chain 8 is connected to the first training panel 3 through the first joint 22, and the second end of the rigid chain 8 is connected to the second training panel 4 through the second joint 23. When the driving mechanism drives the rigid chain 8 to move in one direction, the first end of the rigid chain 8 rises and the second end of the rigid chain 8 drops.

Through such a design, teachers and students can use one of the training panels, such as the first training panel 3, to demonstrate and practice the control circuit. When the control circuit practice on the first training panel 3 is completed, the first training panel 3 is driven downward by the rigid chain 8, and the second training panel 4 is moved upward at the same time. The second training panel 4 that has not been demonstrated can be raised to the top of the training platform 1 for teachers and students to demonstrate and practice, so that the training platform 1 can timely change the demonstrated training content, and is convenient for adjustment and transformation according to the training content, and has high practicality.
