Abstract
Description
Technical Field
[0001] The invention relates to the field of electrical engineering technology, in particular to an electrician skill training platform. Background Art
[0002] Practical training is an important part of cultivating students' professional ability, especially for higher vocational education of electrical and near-electrical majors. Electrical training is the key way for students to master professional skills, and the electrical skills training table is the main equipment for electrical training. At present, there are a large number of complete sets of electrical training devices used in teaching, with complete functions, but they are all developed and designed around certain textbooks or related knowledge points, which is contrary to the integrated training and cultivation of "basic skills for the profession". There are the following shortcomings:
[0003] (1) Electrical control training table. It is developed around factory electrical control technology. Students can use it for circuit assembly training. However, the structure adopts a "hanging box" and "plug-in" structure. All control electrical appliances that do not require hands-on operation are enclosed in the hanging box. During the training, the circuit connection is completed by simply plugging the wire with a special plug into the jack. The training of "basic skills" of electrical workers such as wire insulation stripping and installation is ignored during the operation. The structure and operation process of the enclosed electrical appliances cannot be seen, and students do not even have any perceptual understanding of the electrical appliances. The motors supporting the equipment are placed on the table, and the rotating parts such as couplings have no mechanical protection, which is poor in safety. The maintenance of the equipment still needs to be completed by the manufacturer's after-sales service or professionals. Students do not get the training opportunity to check and troubleshoot actual equipment. In addition, the equipment is expensive.
[0004] (2) Electrician skill training platform. It is developed around the basic operation technology of electricians. The structure generally adopts a mesh and plate structure. During the training, students first install various electrical components on the device and then complete the wiring of the actual circuit. The device can generally only complete the assembly of simple circuits. Some do not have matching motors, and the actual operation of the circuit cannot be verified in time. Even if there are matching motors, the motors still need to be placed on the table for direct wiring. After power is supplied, all the wiring posts are exposed live parts, which poses a great risk of electrical and mechanical injuries. In addition, each training on the device will damage a large number of electrical appliances, which is unimaginable for beginners, greatly increasing the investment in training consumables.
[0005] The above two types of equipment correspond to two independent teaching links of the major, each only serves its own teaching content, and does not take into account the objective law that "the growth of skills requires repeated practice and gradual progress". They are both non-integrated and incomplete training equipment. Summary of the invention
[0006] In order to solve the above technical problems, the present invention proposes an electrician skill training platform with low cost, safe operation and high working transparency.
[0007] The present invention adopts the following technical solution:
[0008] An electrician skill training table comprises a base plate, a frame, a table top and a top plate. The frame is placed on the base plate, the top plate is installed on the top of the frame, the table top is installed horizontally on the front side of the frame, a motor and a speed relay are arranged on the base plate, a front mounting plate, a middle mounting plate and a rear mounting plate are vertically installed on the frame, a terminal row is arranged on the front mounting plate, non-manually operated electrical components are arranged on the rear mounting plate, an operation panel is arranged on the table top, and electrical components that need to be manually operated and adjusted are arranged on the operation panel.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The training cost is low, the training function is comprehensive, and the versatility is strong. The traditional training device has a single function, and this training table can freely combine various electrical components according to the needs of the circuit; the skill exercises are in line with the actual production. This training table can perform wiring exercises that are exactly the same as the actual production in any training, so that students can thoroughly master the basic operations of electricians during school; the circuit work is highly transparent. During the training, students can easily adjust the action parameters of the electrical appliances, can intuitively see the suction and release action process of the electrical appliances, and can also perform wiring exercises in accordance with the wiring of this training table to simplify the process of knowing the wiring rules; it is easy to maintain, all parts and wires of this training table are visible and can be touched. When a fault occurs, the teacher can easily guide students to perform various searches, measurements, repairs and replacements of electrical components; the operation is safe, and this training table is equipped with a leakage protection device. All electrical appliances that need to be operated and adjusted are reliably isolated from the live parts with insulating plates to ensure the safety of students during operation.

[0012] The frame is provided with a front bracket and a rear bracket, the front bracket is provided with front mounting plates at equal intervals, the rear bracket is provided with rear mounting plates at equal intervals, and an intermediate mounting plate is provided between the front bracket and the rear bracket.

DETAILED DESCRIPTION
[0025] The present invention is further described above in conjunction with the accompanying drawings and specific embodiments.
[0026] An electrician skill training platform, composed of a bottom plate 1, a frame 3, a table top 4, and a top plate 11. The frame 3 is an open structure. The bottom of the frame 3 is fixed to the bottom plate 1. A front bracket 301 and a rear bracket 302 are arranged on the frame 3. The tops of the front bracket 301 and the rear bracket 302 are fixed to the bottom surface of the top plate 11. There are two front brackets 301 and two rear brackets 302, respectively. The front bracket 301 and the rear bracket 302 are respectively placed at the left and right ends of the frame 3; a vertically arranged front mounting plate 7 (such as Figure 1 As shown), three front mounting plates 7 are arranged at equal intervals from top to bottom, each front mounting plate 7 is provided with two terminal rows 12, and an electrical graphic symbol 13 is provided between two rows of terminal rows 12 on the same front mounting plate 7.
[0027] A vertically arranged rear mounting plate 8 (such as Figure 1 As shown), three rear mounting plates 8 are arranged at equal intervals from top to bottom, and each front mounting plate 7 is provided with electrical components 9 for non-manual adjustment and operation of fuses, contactors, thermal relays, intermediate relays, control transformers and rectifier devices.
[0028] The frame 3 is provided with an intermediate mounting plate 5, which is vertically arranged between the front mounting plate 7 and the rear mounting plate 8 (such as Figure 1 As shown), the middle mounting plate 5 is provided with electrical components 9 such as an incoming leakage circuit breaker, a circuit master switch and a time relay that are not manually adjusted and operated.
[0029] The lower part of the front bracket 301 is provided with an operation panel 15, on which are mounted electrical components 14 that need to be manually adjusted and operated, such as control buttons, lighting switches, travel switches, leakage circuit breakers, circuit master switches and time relays; a table 4 (such as Figure 1 as shown).
[0030] A speed relay 2 and a motor 16 are installed on the base plate 1 below the frame 3. The motor 16 includes various motors such as a winding motor and a squirrel cage induction motor. A transparent protective plate cover is provided on the outside of each motor 16. The transparent protective plate cover is used for mechanical safety protection during the rotation of the motor 16. A universal wheel 17 is provided on the four corners of the bottom of the base plate 1.
[0031] The content of electrician training can be simply divided into four categories: understanding of electrical components; wiring exercises of simple circuits; assembly of complex circuits; and troubleshooting.
[0032] like Figure 1 , 2 As shown in , 3, and 5, the rear mounting plate 8 is installed with the commonly used non-manually adjusted and operated electrical components 9 in the practical training content, mainly including electrical components such as fuses, contactors, thermal relays, intermediate relays, control transformers and rectifiers of different specifications, the middle mounting plate 5 is installed with the incoming line leakage circuit breaker, transfer switch and time relay and other non-manually adjusted and operated electrical components 9, and the front mounting plate 7 is installed with various terminal blocks 12 and electrical graphic symbols 13; as shown in Figure 3 As shown, the operating panel 15 is equipped with electrical components 14 that need to be manually adjusted and operated, such as control buttons, lighting switches and travel switches, and the manual operation and adjustment parts of the leakage circuit breaker, the main power switch and the time relay are isolated from the live parts behind.
[0033] like Figure 1As shown, this training table has an open frame structure. The motor 16, electrical components and terminal leads 18 of the electrical components installed on the frame 3 can be directly seen around this training table. During the training, under the guidance of the teacher, students observe and identify various control electrical appliances at close range, learn the layout of electrical components, installation and fixing methods, and the routing rules of soft and hard wires. Through simple wiring, they can observe the power-on action and rotation process of equipment such as contactors, intermediate relays and motors 16.
[0034] When a fault occurs on the training platform, the teacher can directly guide the students so that the students can clearly find the fault point on the terminal block 12, and then find the corresponding electrical appliance along the terminal lead 18 and replace it.
[0035] The spacing between the middle mounting plate 5 of the training bench and the front mounting plate 7 and the rear mounting plate 8 is sufficient to ensure that common tools can be used to take out and put in, assemble and disassemble electrical components, making the maintenance of the equipment simple, convenient and time-saving, which not only improves the training efficiency but also cultivates students' fault detection and troubleshooting capabilities.
[0036] like Figure 1 , 2 As shown in , 5, the left and right sides of the training table are respectively provided with electrical components and terminal blocks 12 corresponding to the electrical components. When conducting simple training content, one training table can be practiced by two students at the same time; when conducting common factory control circuit assembly and design training, students can independently select control electrical appliances according to the circuit requirements of the training, and connect them to the corresponding terminal blocks 12; when conducting more complex circuit training such as machine tools, all the electrical components on the training table can be arbitrarily combined (such as Figure 5 As shown in the figure, there is no need to equip different training equipment for different trainings, thus reducing the investment in equipment.
[0037] In various practical wiring exercises, students directly connect the wires on the terminal block 12 of the front mounting plate 7, which prevents students from touching high-cost electrical components, eliminates the possibility of electrical components being damaged, and reduces the cost of practical training.
[0038] This training table adopts a simple frame structure and does not require complicated equipment for production and processing. General factories and even students can complete the production and manufacture of the training table during fitter training and electrician training, which greatly reduces the investment in teaching equipment.
[0039] like Figure 1 , 2As shown in Figures 3 and 4, the training bench installs electrical components with exposed terminal posts on the rear mounting plate 8 and the middle mounting plate 5 respectively. After the terminal protection cover is installed on the terminal block 12 of the front mounting plate 7, there is no exposed conductor that can be directly touched on the surface of the training bench; main circuit switches are provided on the left and right sides of the operating panel 15, and a main line leakage circuit breaker is also provided on the operating panel 15.
[0040] The front and rear mounting plates, the middle mounting plate 5 and the table top 4 of the training platform are respectively made of insulating plates with mechanical strength and high-voltage gas insulation strength to prevent students from being electrocuted by electrical appliances during the training process.
[0041] The above are only specific implementation methods of the present utility model, but the protection of the present invention is not limited to this. All equivalent transformations or replacements of the technical features of the technical solution that can be thought of by technicians in this technical field are covered within the protection scope of the present invention.
