Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering teaching equipment, and particularly relates to an adjustable comprehensive practical training and assessment platform for electrical teaching. Background Art

[0002] Modern electrical comprehensive practical training and assessment platforms and electrician comprehensive skill training devices mainly undertake practical training teaching tasks such as in-class experiments, course designs, and graduation designs for relevant professional courses such as electrical automation technology, industrial robot technology, applied electronics technology, mobile communication technology, mechatronics technology, automotive electronics technology, and building electrical engineering technology. They can be used as classrooms for "teaching, learning, and doing" integrated teaching tasks. Through electrician skill training on the modern electrical comprehensive practical training and assessment platform, students can be intensively trained in the use of common electrician tools, common instruments and meters, lighting and general power wiring, the installation and use of common motors and electrical equipment, and electrician safety operations. This can improve students' practical operation skills in electrical control, residential electricity use, AC and DC motor systems, etc. Subsequently, students can obtain relevant professional certificates such as electrician certificates, electrical engineer certificates, electrical equipment installer certificates, instrument worker certificates, and electrical inspector certificates to better meet the talent requirements of the positions.

[0003] Existing electrical comprehensive practical training and assessment platforms mainly consist of multifunctional mesh board training platforms, power supply devices, etc. During training, various components, devices, and parts selected can be conveniently installed on the mesh board, which is convenient and flexible. Teachers can select different components, devices, and parts according to the needs of teaching and training to conduct practical training for different course modules and different projects. However, the current electrical comprehensive practical training and assessment platforms generally can only complete the examinations and practical operations of electricians. In addition to electrician skills, students or trainees also need to study courses on analog and digital electronics and sensors. Therefore, multiple external circuit boxes need to be used. Different circuit boxes and the training platform are used separately and cannot be centralized, occupying a relatively large amount of space, wasting students' learning time, affecting learning efficiency, and easily leading to the loss of components. For this reason, an adjustable comprehensive practical training and assessment platform for electrical teaching is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the current electrical comprehensive practical training and assessment platforms generally can only complete the examinations and practical operations of electricians. In addition to electrician skills, students or trainees also need to study courses on analog and digital electronics and sensors. Therefore, multiple external circuit boxes need to be used.

The two waste cabinets located at the same place are symmetrically distributed on both sides of the idle slot. Folding slots are opened on both sides of the training platform, and anti-drop cabinets are rotatably installed inside the folding slots. Multiple anti-drop cabinets are respectively located on the top of the idle slots, and two elastic cloths are fixedly installed between the anti-drop cabinets and the inner walls of the folding slots.

[0015] Furthermore, a horizontally arranged limiting groove is opened on the inner wall of the outer flip cover, and limiting hooks are fixedly installed at both ends of the inner part of the limiting groove, and the same limiting elastic rope is sleeved on the two limiting hooks.

[0016] Furthermore, an elastic contact switch is arranged on an inner wall of the temporary parking room on a side away from the component box.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a training integrated component, so that trainees can stand up the mesh plate and lean it against one side of the outer flap to complete the assessment content of various electrician training. After that, the mesh plate can be folded up and pushed into the temporary parking room. At this time, the circuit experiment box will be lifted to the top, and the trainees can complete the assessment content of different analog and digital electrical sensor courses, thereby realizing the centralized training and assessment of electricians and analog electronics, saving training space and time, and improving the efficiency of learning and assessment.

[0019] 2. By setting up the component box and the circuit experiment box, the present invention enables the training personnel to conduct unified electrical engineering training through the component box and the perforated board, and can also carry out different training contents separately on the same training platform. At the same time, each circuit experiment box can be uniformly allocated and replaced, enabling the training personnel to uniformly carry out the same or different courses such as digital electronics and sensors, so that the training assessment platform can meet the flexible course arrangement requirements;

[0020] 3. By setting up the protection component, at the end of the course, the inner flip plate and the outer flip cover can be reset and retracted, and the outer flip cover is limited by the spring lock and the lock plate, so that the training platform is in a storage state, thereby protecting various precision components inside the receiving groove, and at the same time facilitating the storage and transportation of the entire training assessment platform;

[0021] 4. By setting up the waste cabinet, when the training personnel are sitting on both sides of the training platform respectively, the waste cabinets on both sides can be pulled out in turn, and the anti-falling cabinet can be pulled out from the folding groove to collect waste materials, consumables, etc. generated during the training. At the same time, if the training personnel accidentally drop small electrical components out of the training platform, the components will fall into the anti-falling cabinet or the shock-absorbing pad for collection, effectively preventing the components from directly falling on the ground, which is inconvenient for recovery or even loss;

[0022] 5. By setting up the shock-absorbing pad, the components falling inside the waste cabinet and the anti-falling cabinet will be buffered by the shock-absorbing pad on the inner walls of the waste cabinet and the anti-falling cabinet, preventing the components from directly making rigid contact with the inner walls of the waste cabinet and the anti-falling cabinet, thus causing damage to the components;

[0023] 6. By setting up the camera, when the outer flip cover is erected, the camera will face the side where the perforated board and the training personnel are located, so that the camera can shoot the training process of the training personnel, and the operations of the training personnel can be photographed throughout the process, which is convenient for subsequent teaching personnel and the training personnel themselves to watch, facilitating assessment scoring and the training personnel's own summary;

[0024] 7. By setting up the positioning slide bar, after the inner flip plate and the outer flip cover are erected, the positioning slide bars inside the two inner chutes on both sides can be slid and inserted into the two positioning slots on one side of the outer flip cover respectively, so that the outer flip cover and the two inner flip plates are fixed together, effectively preventing the outer flip cover and the inner flip plate from suddenly falling, and at the same time enabling each training personnel to be in a relatively enclosed space during the training process, reducing external interference;

[0025] 8. By setting up the support plate, after the training personnel erect the perforated board, the support plate can be pulled out towards the outside according to their own needs, so that the rubber folding frame stretches itself, adjusting the pulling distance of the support plate, and the support plate supports the perforated board, thereby realizing the adjustment of the flipping angle of the perforated board, and facilitating the training personnel to obtain a better component installation angle;

[0026] 9. The present invention sets a limiting elastic cord, so that before the mesh plate is turned over and leaned against one side of the outer flip cover, the limiting elastic cord can be pre-removed from the limiting groove, and then the limiting elastic cord is hung on one of the limiting hooks, so that the limiting elastic cord passes through one side of the mesh plate and is hung on the limiting hook at the other end, and the limiting elastic cord limits the mesh plate, effectively preventing the components on the mesh plate from being caught by the hands or clothes of the training personnel and driving the mesh plate to suddenly turn over and fall.

[0027] 10. The present invention sets an elastic contact switch, so that during the process of switching training contents, the component box needs to be pushed into the temporary parking room. When the component box touches the elastic contact switch, the control circuit is connected, and at this time, the lifting electric push rod can drive the circuit experiment box to lift, so that the circuit experiment box can only rise when the hanging slide plate is retracted in place, effectively preventing the circuit experiment box from colliding and squeezing with the corners of the hanging slide plate.

[0043] The training integration components are used to provide equipment required for electrical training and analog electronics courses for students at the same time, such as Figure 5 , Figure 6 As shown, the training integration component includes a T-shaped receiving box 2 fixedly installed inside the receiving groove. A training room 201, a temporary parking room 202, and a power room 203 that communicate with each other are arranged inside the T-shaped receiving box 2. The temporary parking room 202 is located on one side of the training room 201, and the power room 203 is located at the bottom of the training room 201. In this embodiment, a plurality of T-shaped receiving boxes 2 are symmetrically distributed in two rows inside the training platform 1, and the temporary parking rooms 202 are all arranged on the side where the two rows of T-shaped receiving boxes 2 are close to each other. Inside the training room 201, a component box 3 and a circuit experiment box 4 are arranged in sequence from top to bottom. A mesh plate 5 is rotatably installed on the top of the component box 3. Long sliding grooves that communicate with each other are opened on both sides of the training room 201 and the temporary parking room 202. Suspension sliding plates 6 adapted to the long sliding grooves are fixedly installed on both sides of the component box 3. A support frame 7 is fixedly installed inside the power room 203. A vertically arranged lifting electric push rod 8 is fixedly installed on the top of the support frame 7. The telescopic end of the lifting electric push rod 8 extends into the training room 201 and is fixedly installed with a lifting frame 9. The circuit experiment box 4 is fixedly installed on the top of the lifting frame 9. In this embodiment, the circuit experiment box 4 and the lifting frame 9 are detachably connected by means of plugging, screwing, etc.;

[0044] A protection component for closing the receiving groove is arranged on the top of each receiving groove, such as Figure 3 As shown, the protection component includes two inner turning plates 10 respectively rotatably installed on both sides of the top of the receiving groove. The two inner turning plates 10 are symmetrically distributed. An outer turning cover 11 is rotatably installed on one side of the top of the receiving groove. Both inner turning plates 10 are located at the bottom of the outer turning cover 11. A spring lock 12 is fixedly installed on the top of the training platform 1, such as Figure 7 As shown, a lock plate 13 adapted to the spring lock 12 is fixedly installed on one side of the top of the outer turning cover 11. In this embodiment, a plurality of embedded magnetic attraction strips can be arranged on the top of the training platform 1 for adsorbing and positioning the outer turning cover 11 and the inner turning plates 10 after they are turned up, so as to realize temporary fixation and prevent the outer turning cover 11 and the inner turning plates 10 from suddenly falling down;

[0045] Such as Figure 3As shown in the figure, an in - built socket 14 is fixedly installed at the top of the accommodation groove. In this embodiment, the in - built socket 14 is connected to a 12 / 15V or AC 17 / 24V power supply and can be switched uniformly to meet the dual - power requirements of the training. On both sides of the training platform 1, a plurality of evenly - distributed idle grooves 101 are provided. The positions of the plurality of idle grooves 101 correspond to the positions of the plurality of T - shaped accommodation boxes 2 respectively. In this embodiment, the accommodation grooves are respectively used for installing the inner grooves of the T - shaped accommodation boxes 2 and the outer grooves for storing the inner flaps 10 and the outer covers 11. The in - built socket 14 is installed inside the outer groove. The two inner flaps 10 cover the top of the mesh plate 5, and the outer cover 11 covers the tops of the inner flaps 10 and the in - built socket 14. As Figure 1 shown, a programming computer 15 is placed on the top of the training platform 1, and a storage cabinet 16 is arranged on one side of the training platform 1; specifically, when the adjustable electrical teaching comprehensive training and assessment platform is in use, first press each spring lock 12 to release its locking of the outer cover 11 with the lock plate 13, then turn up the outer covers 11 and the inner flaps 10 on both sides in sequence to open the accommodation grooves in sequence, then take out the programming computer 15 from the storage cabinet 16 and connect the power supply. By setting the training integration components, the training personnel can set up the mesh plate 5 and lean it against one side of the outer cover 11, then take out various components from the lower component box 3, install the corresponding components on the mesh plate 5 according to the training content, then wire and test, or connect to the PLC and perform programming tests on the programming computer 15 beside in sequence, so as to complete the assessment content of various electrical engineering training items. After that, the mesh plate 5 can be put away and pushed into the temporary parking room 202. At this time, the lifting electric push rod 8 inside the power room 203 will drive the circuit experiment box 4 to lift upwards through the lifting frame 9 until the circuit experiment box 4 reaches the top of the training room 201. The training personnel can open the circuit experiment box 4 and complete the assessment content of different analog and digital electronic sensor courses, realizing the centralized training and assessment of electrical engineering and analog electronics, saving training space and time, and improving the efficiency of learning and assessment. By setting the component box 3 and the circuit experiment box 4, the training personnel can conduct unified electrical engineering training through the component box 3 and the mesh plate 5, and can also carry out different training contents on the same training platform 1 respectively. At the same time, each circuit experiment box 4 can be uniformly allocated and replaced, enabling the training personnel to uniformly conduct the same or different digital electronics, sensor and other courses, so that the training and assessment platform can meet the flexible curriculum arrangement requirements. By setting the protection components, at the end of the course, the inner flaps 10 and the outer covers 11 can be reset and put away, and the outer cover 11 can be limited by the spring lock 12 and the lock plate 13 to make the training platform 1 in a storage state, thereby protecting various precision components inside the accommodation groove, and at the same time facilitating the storage and transportation of the entire training and assessment platform.

[0046] As Figure 3As shown, a plurality of cabinet slots are provided on both sides of the training platform 1, and waste cabinets 17 are slidably installed inside the cabinet slots. Two waste cabinets 17 located at the same place are symmetrically distributed on both sides of the idle slot 101. A folding slot is provided on both sides of the training platform 1, and anti-drop cabinets 18 are rotatably installed inside the folding slots. The plurality of anti-drop cabinets 18 are respectively located on the top of the idle slot 101, as shown in FIG. Figure 4 As shown, two elastic cloths 19 are fixedly installed between the anti-drop cabinet 18 and the inner wall of the folding groove, and multiple sliding latches 20 are slidably installed on both sides of the training platform 1. The three sliding latches 20 located at the same place correspond to the positions of the anti-drop cabinet 18 and the two waste cabinets 17 respectively, and the inner walls of the cabinet grooves are provided with yield grooves 102; specifically, by arranging the waste cabinets 17, when the trainees sit on both sides of the training platform 1 respectively, the waste cabinets 17 on both sides can be pulled out in turn, and the anti-drop cabinet 18 can be pulled out from the folding groove to store waste materials, consumables, etc. generated during the training process. At the same time, if the trainees accidentally drop small electrical components out of the training platform 1, the components will fall into the anti-drop cabinet 18 or the shock-absorbing pad 21 for storage, which effectively prevents the components from falling directly to the ground and being inconvenient to be recovered, or even lost.

[0047] like Figure 4 As shown, shock-absorbing pads 21 are fixedly installed on the inner walls of the waste cabinet 17 and the anti-drop cabinet 18; specifically, by providing the shock-absorbing pads 21, the components dropped into the waste cabinet 17 and the anti-drop cabinet 18 will be cushioned by the shock-absorbing pads 21 on the inner walls of the waste cabinet 17 and the anti-drop cabinet 18, preventing the components from directly and rigidly contacting the inner walls of the waste cabinet 17 and the anti-drop cabinet 18, thereby causing damage to the components.

[0048] like Figure 7 As shown, a camera 22 is fixedly mounted on the top of the outer flip cover 11 away from the lock plate 13. Figure 9 As shown, the side walls of the inner flap 10 are provided with avoidance grooves 1001 adapted to the camera 22; specifically, by arranging the camera 22, when the outer flap 11 is erected, the camera 22 will face the side where the mesh plate 5 and the trainee are located, so that the camera 22 can shoot the training process of the trainee, so that the trainee's operation can be fully photographed, which is convenient for subsequent teaching staff and trainees to watch by themselves, and convenient for assessment scoring and the trainee's own summary.

[0049] like Figure 9 As shown, the inner wall of the inner flap 10 is provided with an inner slide groove 1002, and a positioning slide rod 23 is slidably installed inside the inner slide groove 1002. Figure 7As shown in the figure, two positioning slots 1101 adapted to the positioning slide rods 23 are provided on the inner wall of the outer flip cover 11, and a limiting magnetic attraction block 24 is fixedly installed on one side of the inner chute 1002 away from the positioning slide rod 23. Specifically, by setting the positioning slide rods 23, after the inner flip plate 10 and the outer flip cover 11 are erected, the positioning slide rods 23 inside the two inner chutes 1002 can be slid and inserted into the two positioning slots 1101 on one side of the outer flip cover 11 respectively, so that the outer flip cover 11 and the two inner flip plates 10 are fixed to each other, effectively preventing the outer flip cover 11 and the inner flip plate 10 from suddenly falling, and at the same time, each training person can be in a relatively enclosed space during the training process, reducing external interference.

[0050] As Figure 7 shown in the figure, a support groove 1102 is provided on the inner wall of the outer flip cover 11, a rubber folding frame 25 is fixedly installed inside the support groove 1102, and a support plate 26 is fixedly installed on one side of the rubber folding frame 25. Specifically, by setting the support plate 26, after the training person erects the mesh plate 5, the support plate 26 can be pulled out towards the outside according to his own needs, so that the rubber folding frame 25 stretches itself, adjusts the pulling-out distance of the support plate 26, and makes the support plate 26 support the mesh plate 5, thereby realizing the adjustment of the flipping angle of the mesh plate 5 and facilitating the training person to obtain a better component installation angle.

[0051] As Figure 7 shown in the figure, a horizontally arranged limiting groove 1103 is provided on the inner wall of the outer flip cover 11. As Figure 8 shown in the figure, limiting hooks 27 are fixedly installed at both ends inside the limiting groove 1103, and the same limiting elastic cord 28 is sleeved on the two limiting hooks 27. Specifically, by setting the limiting elastic cord 28, before the mesh plate 5 is flipped and leaned against one side of the outer flip cover 11, the limiting elastic cord 28 can be pre-removed from the limiting groove 1103, and then the limiting elastic cord 28 is hung on one of the limiting hooks 27, so that the limiting elastic cord 28 passes through one side of the mesh plate 5 and is hung on the limiting hook 27 at the other end, so that the limiting elastic cord 28 limits the mesh plate 5, effectively preventing the components on the mesh plate 5 from being caught by the hands or clothes of the training person and driving the mesh plate 5 to suddenly flip and fall.

[0052] As Figure 6As shown in the figure, an elastic contact switch 29 is provided on the inner wall of the side of the temporary parking room 202 away from the component box 3. In this embodiment, the elastic contact switch 29 is electrically connected to the lifting electric push rod 8 through a control circuit. Specifically, by setting the elastic contact switch 29, during the process of switching from electrical engineering training to analog electronics courses, it is necessary to push the component box 3 into the temporary parking room 202. When the component box 3 contacts the elastic contact switch 29, the control circuit is connected, and at this time, the lifting electric push rod 8 can drive the circuit experiment box 4 to lift, so that the circuit experiment box 4 can only rise when the hanging slide plate 6 is retracted in place, effectively preventing the circuit experiment box 4 from colliding and squeezing with the corners of the hanging slide plate 6.

[0053] In summary: Before use: First, press each spring lock 12 to release its locking of the outer flip cover 11 with the lock plate 13, then turn up each outer flip cover 11 and the inner flip plates 10 on both sides in sequence, slide the positioning slide rods 23 inside the inner chute 1002 on both sides, and insert them into the two positioning slots 1101 on one side of the outer flip cover 11 respectively, so that the outer flip cover 11 and the two inner flip plates 10 are fixed to each other, effectively preventing the outer flip cover 11 and the inner flip plates 10 from suddenly falling. At this time, the accommodation grooves are opened in sequence, then take out the programming computer 15 from the storage cabinet 16 and connect the power supply. When the training personnel sit on both sides of the training platform 1 respectively, the waste material cabinets 17 on both sides can be pulled out in sequence, and the anti-falling cabinet 18 can be pulled out from the folding groove;

[0054] Electrical engineering training: The training personnel pre-take out the limit elastic cord 28 from the limit groove 1103, hang the limit elastic cord 28 on one of the limit hooks 27. The training personnel can set up the mesh plate 5 and lean it against one side of the outer flip cover 11, and can pull out the support plate 26 outward according to their own needs, so that the rubber folding frame 25 stretches itself, adjust the pulling distance of the support plate 26, so that the support plate 26 supports the mesh plate 5, thereby realizing the adjustment of the flipping angle of the mesh plate 5. Then make the limit elastic cord 28 pass through one side of the mesh plate 5 and hang it on the limit hook 27 at the other end, so that the limit elastic cord 28 limits the mesh plate 5. After that, various components can be taken out from the component box 3 below, and the corresponding components can be installed on the mesh plate 5 according to the training content, then wire and test, or connect the PLC, and perform programming tests on the programming computer 15 beside in sequence, so as to complete the assessment content of various electrical engineering training;

[0055] Analog electronics courses: Put away the mesh plate 5 and push it into the temporary parking room 202. When the component box 3 contacts the elastic contact switch 29, the control circuit is connected. At this time, the lifting electric push rod 8 inside the power room 203 will drive the circuit experiment box 4 to lift upward through the lifting frame 9 until the circuit experiment box 4 reaches the top of the training room 201. The training personnel can open the circuit experiment box 4 and complete the assessment content of different analog and digital electronics sensor courses;
