Description

The utility model relates to the field of educational technology, in particular, to stands for laboratory work in schools, secondary specialized and higher educational institutions in the disciplines: general physics, electrical and magnetic circuits, theoretical foundations of electrical engineering, electroautomatics.

A well-known laboratory bench for electrical engineering (RF patent No. 53056, IPC G09B 25/00, 04/27/2006), made in a portable case, containing a composing field with passive and active elements, electronic components and measuring instruments, a composing field is made of sheet insulating material with the front coating contains metal socket contacts and drawings of electrical elements and circuit diagrams, fortified from the inside of the type-setting field.

The disadvantages of the laboratory stand are: the limited number of laboratory work performed, the inability to use this stand for demonstration and laboratory work in a large audience, the structural complexity and high cost, the need for miniature units and devices. The lack of proper remote control by the teacher does not allow the prompt implementation of the educational process.

A well-known multifunctional laboratory bench simulating automatic process control systems (RF patent No. 84158, MKPO 14-02, 01/16/2013) is characterized by a bench body and a base, four wheels on the base, a horizontal work surface in the form of a tabletop, and the presence of a base on both sides shelves, the original background image on the vertical front surface, the presence on the vertical front surface of a rectangular metal perforated panel, the location of the function tional elements on the vertical front and back vertical surfaces, the presence of functional elements disposed on the vertical front and back vertical surfaces, and the presence of emergency stop button panel placed therein to electrical machines.

The disadvantage of the analogue is the bulkiness of the structure, due to the large overall dimensions, as well as a small number of possible works.

A training table in electrical engineering is known (RF patent No. 85725, IPC G09B 23/18, 08/10/2009), which is a table to which two vertical racks are attached to the tabletop, to which, in turn, perforated panels are attached, which are necessary to fix the necessary devices for laboratory work. The table also contains a set of simulators of electrical equipment, a set of wires, a power supply.

The disadvantage of this design are: the large overall dimensions of the table, the inconvenience of working, the need for each laboratory work to change perforated panels, disassemble the old one and collect a new circuit, which takes a lot of time.

The closest to the proposed utility model is a training and laboratory stand (RF patent No. 140456, IPC G09B 23/18, 05/10/2014) containing a functional generator equipped with a frequency counter, a power source, measuring instruments and an indication and control panel made in a modular scheme of two or more cases attached to each other by easily removable mechanical connections, providing, inter alia, the electrical connection of the mating bodies, one of the cases being an independent device, and the rest of the case - self-contained modules with an agreed set of elements studied electrical and electronic circuits, and measuring devices.

The disadvantage of this stand is the need to attach the housings to each other to ensure their mechanical and electrical connection, which leads to the bulkiness of the entire structure and limits the training and demonstration capabilities of the laboratory stand.

The objective of this utility model is to expand the functionality of the training and laboratory module, increase the effectiveness of training and the convenience of the teacher while increasing the range of training equipment, quickly replaced in the learning process.

The technical result is the ability to install in the training and laboratory module required for upcoming laboratory work removable panels and their connection with each other in any combination and in any sequence.

The problem is solved, and the technical result is achieved by the fact that in the training and laboratory module containing the frame with legs and handles, a power source, mounted on removable panels elements of the studied electrical and electronic circuits, which are equipped with connectors for assembling electrical circuits of the training and laboratory module, measuring instruments, according to a utility model, removable panels are made of the same size and a set of wires is made with plugs at the ends of each wire with the possibility of placing removable panels front and rear side of the module as well as in any combination and in any order.

The essence of the utility model is illustrated by drawings and photographs.

FIG. 2 - Wire with plugs at the ends.

FIG. 3 - Side view.

In FIG. 4 presents a General view of the educational laboratory module.

In FIG. 5 is a front view.

In FIG. 6 shows a removable panel for the study of RCDs.

In FIG. 7 shows a removable panel for studying three-phase circuits.

In FIG. 8 shows a removable panel - power supply.

The training and laboratory module includes removable panels 1 (Fig. 1), with the necessary number of equipment simulators and socket contacts installed on them, necessary for collecting the electrical circuit using wires 2 with 3 plugs at the ends (Fig. 2). The panels are attached by means of four blind nuts 4 (Fig. 1, Fig. 3), which are screwed onto the studs located in the corners, according to the dimensions of the removable panel. On the upper part there are handles 5 (Fig. 4) for transportation. At the bottom of the training and laboratory module are legs 6 (Fig. 6, Fig. 7, Fig. 8), providing a stable position and protection from various damage to the surfaces on which the module is located. The utility model can be installed on any horizontal surface (table, shelf, object table, school desk).

The training and laboratory module works as follows:

The removable panels 1 (Fig. 6, Fig. 7, Fig. 8) are attached by means of four blind nuts 4, which are screwed onto the studs (not shown in the drawing). The possibility of transportation is provided by handles 5 (Fig. 1, Fig. 3, Fig. 4, Fig. 5) located on the top of the module. By means of legs 6 (Fig. 1, Fig. 3) they provide a stable position and protection against various damage to the surfaces on which the module is located. The training and laboratory module is connected to the mains using an electric wire with an electric plug at the end (Fig. 2). In advance, on the necessary removable panels 1 (Fig. 6, Fig. 7, Fig. 8), the electric circuit specified by the teacher is assembled using wires 2, with plugs 3 at the ends, and all missing devices are also connected using wires 2.

So, the claimed utility model allows you to expand the functionality of the training and laboratory module, increase the effectiveness of training and the convenience of the teacher while increasing the range of training equipment, quickly replaced in the learning process. In addition, it is possible to install detachable panels and connect them to each other in the training and laboratory module required for the upcoming laboratory work in a predetermined combination and in the given sequence required for laboratory work. Preset combinations and sequences can be any.
