Disadvantages: the complexity of the design of the installation and the low level of automation of the fueling process.

Known station for refueling fire extinguishers with carbon dioxide according to CN patent for the invention No. 103032672A, PMK F17C 13/00, publ. 04/10/2013, the prototype.

This station contains containing scales, containing, in turn, a flat rectangular platform.

Disadvantage: difficult installation of cylinders and fire extinguishers on the weighing platform due to the need to lift heavy cylinders and fire extinguishers to a considerable height.

The task of creating a utility model: facilitating the installation of cylinders and fire extinguishers on a weighing platform.

The technical result of the claimed technical solution is to facilitate the installation of cylinders and fire extinguishers on the weighing platform.

The solution to this problem was achieved in a carbon dioxide filling station, which contains a scale, which in turn contains a flat rectangular platform, the platform being low-profile and having a “P” -shaped protruding around the periphery, the protruding border is formed by two parallel shrouds and rear ledge.

The carbon dioxide filling station may include a filling line with a valve and a control system, and the control system is electronic and contains a control panel and load cells mounted on the beams of the scales.

Beams can have two adjusting supports. Beams can be covered with casings. The cradles of the beam can be fixed on the casing. Lodges can be made in the form of segments. The control unit can be made with indicators and control buttons and connected by cables to the network and load cells. The control unit can be made in the form of a parallelepiped with indicators and control buttons and is connected by cables to the network and load cells.

The essence of the utility model is illustrated in FIG. 1-6, where:

- in FIG. 1 shows a diagram of the station,

- in FIG. 2 shows the platform of the scales,

- in FIG. 3 shows the control unit,

- in FIG. 4 shows a beam with a load cell,

- in FIG. 5 shows a refueling control circuit,

- in FIG. 6 shows a diagram of the management of refueling cylinders.

The proposed station is intended for refueling cylinders (or fire extinguishers) 1 (Fig. 1) with natural gas along line 2 containing valve 3. Valve 3 is made remotely controlled. In line 2, a pump with an electric motor 4 is installed.

The basis of the filling station for refueling carbon dioxide cylinders are scales 5, containing a platform 6 of a flat rectangular shape (Fig. 2). Platform 6 is made low profile, i.e. has the lowest possible height. The platform 6 has a protruding edging 7 "P" -shaped around the periphery. The protruding edging 7 is formed by two parallel casings 8 and a rear ledge 9. The cradles 10 are fixed on the casings 8 (Fig. 2). Lodgements 10 may be in the form of a circular arc. Inside the casings 8 (in Fig. 4, the casing 8 is not shown), beams 11 are mounted on which load cells 12 are fixed (Fig. 4). Two adjustable supports 13 are attached to each beam 11 (Figs. 1 and 4).

The implementation of the platform 6 low profile and the use of the protruding edging 7 "P" -shaped shape facilitates the installation of the cylinder 1 on the scales 5.

The carbon dioxide filling station comprises a control unit 14 having a front panel 15 on which three control buttons are located (Fig. 3)

Stop button 16, additional functions: zeroing, taring, output,

Start button 17, additional functions: zeroing and increasing the dose,

Dose Reduction button 18.

Also on the front panel 15 are placed (Fig. 3) a digital indicator 19 and signal lamps "Dose" 20 and a LED "Pressure" 21. On the left on the front panel 15 there is a circuit breaker 22 with three switches 23.

A power cord 24 and cables 25 are connected to the control unit 14 (Fig. 1). The control channel 26 connects the control unit 14 to the remote-controlled valve 3.

In FIG. 5 shows the electrical circuit for monitoring and indicating the refueling process. It contains a power cord 24 connected to a transformer 27, to the output of which wires 28 and 29 are connected for supplying a digital indicator 19 and a dose LED 20 and a pressure LED 21. Digital indicator 19 and LEDs 20 and 21 are connected to wire 28 through normally open contacts 30, 31 and 32 of the respective relays.

In FIG. 6 shows a control diagram for refueling a cylinder 1. It contains, connected by electrical connections 33 and 34 to a transformer 27 of the ADC 35 (analog-to-digital converter) with a microprocessor 36, which is connected via a communication channel 37 to a relay 38, whose normally open contact 39 is installed in the electrical communication circuit 33 connected to a remote-controlled valve 3.

STATION WORK

The station operates as follows (Fig. 1-6). The power cord 24 of the control unit 14 is included in the electrical network. Turn on the circuit breaker 22. Zero the readings of the digital indicator 19 with the Stop button 16.

Install the cylinder 1 on the platform 6, determine its weight and begin to charge. Set the required dose with the Stop button 16, which has additional functions, and hold it until the value of the desired carbon dioxide dose flashes on the digital indicator 19.

Press the “Start” button 17, after which the “Dose” LED will light up.

After reaching the set dose of refueling, the electric motor 4 of the pump (Fig. 1) turns off automatically.

Application of the utility model allowed:

- to provide automation of the process of filling cylinders and fire extinguishers with carbon dioxide,

- facilitate the installation of cylinders and fire extinguishers on the weighing platform,

- to simplify the maintenance of the platform: its cleaning of foreign debris and moisture.

- eliminate refilling of cylinders and fire extinguishers,

- increase the accuracy of dosage and control of the filling.
