Description

Technical Field

[0001] This utility model relates to the field of electrical technology application technology, and more specifically, to a training and assessment device for electrical equipment installers. Background Technology

[0002] Against the backdrop of rapid development in the electrical industry, the practical skills of electrical equipment installers are directly related to the safe operation of electrical systems. Traditional training models rely on theoretical teaching and lack real-world scenario operation, leading to problems such as wiring errors and non-standard processes in key aspects such as wiring and component installation. Existing practical training and assessment devices have limited functions, only capable of basic circuit connections and simple tests, unable to simulate complex faults such as aging electrical components, short circuits, and open circuits, making it difficult to cultivate trainees' ability to handle real-world working conditions. In addition, the assessment process is highly subjective, focusing on results while neglecting core elements such as operational standardization and safety, resulting in a disconnect between trainees' actual operational skills and assessment scores. Furthermore, with the popularization of intelligent and automated technologies, existing devices have failed to integrate new technologies such as PLC control and frequency converter debugging, failing to meet the industry's training needs for multi-skilled personnel.

[0003] Therefore, there is an urgent need for a training device that can simulate real working conditions, support multiple fault scenarios, integrate new technologies, and have objective assessment functions, in order to solve the technical problems of insufficient flexibility, unscientific assessment standards, and low resource utilization in traditional training.

This invention utilizes a zoned design and a fault line extraction port to enable multi-scenario operation and fault simulation, thereby improving the efficiency of practical training.

[0005] To achieve the above objectives, this utility model provides an electrical equipment installation worker training and assessment device, including an integrated training and assessment platform. The integrated training and assessment platform is divided into a front operation area, a rear wiring area, and an under-table storage area. The front operation area, the rear wiring area, and the under-table storage area are functionally independent but cooperate with each other. The front operation area includes a modular panel and a herringbone cable tray, the rear wiring area includes a cable tray, and the under-table storage area includes a rotatable cable reel.

[0006] Furthermore, the modular panel is provided with standardized mounting holes for installing air switches, DC power supplies, cable outlets, analog panels, PLCs, isolators, intermediate relays, buttons, indicator lights, thermal relays, contactors, frequency converters, and terminals. The modular panel can quickly build different types of electrical control systems by combining different electrical components.

[0007] Furthermore, the modular panel integrates an electrical control system, a local operation unit, a remote operation interface, and an external terminal block. The local operation unit includes buttons, the remote operation interface includes a PLC and a simulation screen, and the external terminal block is used to realize external wiring linkage between the control system and the operating system.

[0008] Furthermore, the fishbone cable channel is fixedly installed on the surface of the modular panel, and the fishbone cable channel is provided with a fault cable extraction port.

[0009] Furthermore, the cable tray is fixed to the back of the panel of the rear wiring area, and the cable tray adopts an open trough structure or a mesh structure.

[0010] Furthermore, the rotatable cable reel is installed at the footrest position in the storage area under the table. Different specifications of cables are pre-wound in the rotatable cable reel. One end of the cable is fixed to the rotatable cable reel, and the other end can be pulled out to the front operating area for use. The rotatable cable reel is equipped with length markings so that students can pull out the cable as needed.

[0011] Furthermore, the rotatable cable reel achieves cable recycling through rotation. The rotatable cable reel is used in conjunction with the cable tray.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0027] like Figures 1 to 2 As shown, this utility model provides an electrical equipment installation worker training and assessment device, including an integrated training and assessment platform. The integrated training and assessment platform is divided into a front operation area 1, a rear wiring area 2, and an under-table storage area 3. The front operation area 1, the rear wiring area 2, and the under-table storage area 3 are functionally independent but cooperate with each other. The front operation area 1 includes a modular panel 124 and a herringbone cable tray 123. The rear wiring area 2 includes a cable tray 211. The under-table storage area 3 includes a rotatable cable reel 311.

[0028] By simulating real production scenarios through functional zoning design, the system restores the linkage scenario of "control-operation-wiring" and improves the adaptability of trainees to practical operation. The cable tray 211 and the rotatable cable reel 311 are used together to improve the standardization of wiring operations and resource utilization, and solve the problems of insufficient flexibility and scenario disconnect of traditional training devices.

[0029] Furthermore, the modular panel 124 is fixedly mounted on the table 4 via the control board 5. The modular panel 124 is provided with standardized mounting holes for installing air switches 111, DC power supplies 112, cable outlets 113, simulation panels 114, PLCs 115, isolators 116, intermediate relays 117, buttons 118, indicator lights 119, thermal relays 120, contactors 121, frequency converters 122, and terminal blocks. The modular panel 124 allows for the rapid construction of different types of electrical control systems by combining different electrical components. The modular design meets the needs of different training content, enhancing the flexibility and adaptability of the device. The standardized mounting holes simplify the component installation process, shorten training preparation time, and improve training efficiency.

[0030] Furthermore, the modular panel is equipped with an electronic timer and an operation step recorder to automatically record wiring time and operation steps; the legs of table 4 are equipped with casters for easy movement.

[0031] Furthermore, the modular panel 124 integrates an electrical control system, a local operation unit, a remote operation interface, and an external terminal block 125. The local operation unit includes a button 118, the remote operation interface includes a PLC 115 and a simulation screen 114, and the external terminal block 125 is used to realize external wiring linkage between the control system and the operating system. The electrical control system includes manual motor control and automatic centralized control. By combining local and remote operation, the trainee's adaptability to complex operation scenarios is improved.

[0032] Furthermore, the fishbone cable tray 123 is fixedly installed on the surface of the modular panel 124. The fishbone cable tray 123 is used to organize the connecting wires and avoid messy wiring. The fishbone cable tray 123 is provided with several fault wire extraction ports. The fault wire extraction ports are used to insert preset fault wires to simulate fault points such as short circuits and open circuits. The fault wire extraction ports support quick setting and restoration of fault points, simplifying the fault assessment process and improving assessment efficiency.

[0033] Furthermore, the cable tray 211 is fixed to the back of the panel of the rear wiring area 2. The cable tray 211 adopts an open trough structure or a mesh structure. The cable tray 211 is used to simulate the cable laying path in the industrial field. Trainees need to lay and fix cables in the cable tray 211 and complete the connection at both ends, which improves the trainees' cable laying and routing planning ability. In addition, the open or mesh structure makes it easy to observe the wiring operation and strengthens the standardized training.

[0034] Furthermore, the rotatable cable reel 311 is installed at the footrest position in the storage area 3 under the table. Different specifications of cables are pre-wound in the rotatable cable reel 311. One end of the cable is fixed to the rotatable cable reel 311, and the other end can be pulled out to the front operation area 1 for use. The rotatable cable reel 311 is equipped with length markings so that trainees can pull out cables as needed. The rotatable cable reel 311 pre-wound cables of various specifications, reducing redundant configurations and saving resources. The length markings and the rotatable retraction function improve the efficiency of cable extraction and storage and keep the device tidy.

[0035] Furthermore, the rotatable cable reel 311 achieves cable recycling through rotation. The rotatable cable reel 311 is used in conjunction with the cable tray 211. The cable tray 211 is provided with a detachable fixing buckle. The fixing buckle is used to fix the laid cable and realize the quick reset of the wiring area. The cooperative design of the rotatable cable reel 311 and the fixing buckle realizes the quick reset of the wiring area, meets the requirements of high-intensity and fast-paced assessment, and the detachable fixing buckle facilitates cable fixing and adjustment, improving the convenience of operation.

[0036] Implementation process of this device:

[0037] Operators install electrical components in the front operating area 1 of the training and assessment platform through the standardized mounting holes on the modular panel 124, build the target electrical control system, and connect the wires neatly through the herringbone cable tray 123.

[0038] During the assessment, judges randomly insert pre-set fault lines through the fault line extraction port, and trainees must troubleshoot and repair the faults within a specified time. Simultaneously, trainees lay cables according to the drawings in the cable tray 211 in the rear wiring area, complete the terminal head fabrication, and extract cables as needed through the rotatable cable reel 311 in the under-table storage area. The reel's length markings ensure accurate retrieval.

[0039] The electronic timer 126 and operation step recorder 127 on the front operation area panel automatically record the wiring time and fault handling data, and the referee can evaluate the wiring standardization in real time through the observation window.

[0040] After the assessment, the rotatable cable reel 311 rotates in the opposite direction to recycle the cable, and the fixing clip assists in quickly resetting the wiring area, achieving efficient reuse and multiple rounds of continuous assessment.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
