Description

The in-house fire extinguishing device is intended for manual use as the primary means of extinguishing emerging fires at an early stage before the arrival of a specialized fire fighting unit. The device is connected to the cold water pipeline in residential and industrial premises.

A device is known for the in-house fire extinguishing of the PDA-Pulse, a patent for a utility model No. 32701.

The known device, comprising a housing formed by upper, lower, side and rear stacks, a door, a door opening and turning mechanism, has a flexible pipe spraying nozzles, a fitting secured in one of the holes made in the upper, lower and side walls.

The disadvantage of the device described above is the lack of controlled water supply to the flexible pipe and controlled water shutdown.

The objective of the proposed utility model should be to provide a visual inspection of the supply mechanism (shut off the supply) of water into the flexible pipe of the device while simultaneously generating electrical signals to the external circuits of the fire automatics (signaling).

The fulfillment of the goal allows controlling the duty and operating status of the feeder (shut-off unit) on site and remotely, for example, in the duty fire station.

This goal is achieved by creating an internal fire extinguishing device comprising a housing formed by upper, lower, side and rear walls, a door, a door opening and turning mechanism, a flexible pipe with a spray nozzle at the exit end, according to the utility model, a faucet is installed at the inlet end of the flexible pipe , which is equipped with a knob to control the position of the handle of the crane.

The crane with a knob for controlling the position of the crane handle has a control knob with two platforms (flags) spaced apart, with the ability to switch one pad of only one of the two sensors to control the position of the handle (operating or standby status of the crane), while the sensors are installed in the electrical box, which it is fixed by means of a bracket on the crane; the box has two electrical pressure seals and an internal board with two electrical connectors.

Each position control sensor is made in the form of an optocoupler relay with “dry contacts”, while the electrical outputs of the “dry contacts” relay are connected via the first pressure input, the electrical contacts of the LEDs are connected via the second pressure input to the power supply.

Both sensors for controlling the position of the handle in the form of inductive contactless or in the form of contact limit switches are possible.

The proposed design of the input end of the flexible hose with a crane mounted on the end with a knob for controlling the position of the handle allows you to visually monitor the condition of the crane by the position of the handle relative to the longitudinal axis of the crane, automatically transmit information about the position of the handle by means of sensors controlling the position of the handle.

The utility model is illustrated by drawings.

FIG. 1 shows a general view of an internal apartment fire extinguishing device; FIG. 2 shows a general view of the control knob position control unit; FIG. 3 shows an electrical circuit diagram of the valve handle position control unit.

The in-house fire extinguishing device has a body 1 formed by upper, lower, side and rear stacks, a door, a door opening and turning mechanism, a flexible pipe 2 mounted on the rotary drum 3, a crane 4 with a knob for controlling the position of the handle 5 mounted on inlet 6 to the flexible the pipeline spraying the nozzle (or barrel) 7 at the exit 8 of the flexible pipe, while the crane has a control knob 9 with two sites 10 and 11, each site being designed to shut off the photosensitive window of one of the two optics The sensor controls the position of the handle of the crane 12 or 13, which are installed in the box 14. The sensors have “dry contact” terminals, connection to which can be made through a pressure seal 15 and connector 16, and the connection to the corresponding LEDs of the sensors can be made through connector 17 and hermovod 18, and the connectors are installed in the box 14, the sealed inlets 15, 16 - on the side walls of the box, the box is installed by means of the bracket 19 on the crane 4.

The closed position of the crane is characterized by the transverse position of the handle 9 of the crane 4 relative to the axis of the crane, while the platform 11 overlaps the photosensitive window of the sensor 13; when the crane is open, the handle is located along the axis of the crane, while the pad 10 overlaps the photosensitive window of the sensor 12.

The overlap of one of the two photosensitive sensor windows triggers the corresponding “dry contact” of the sensor; tripping signals from sensors can be transmitted via external fire automatics circuits, which are connected via connectors 16, 17 and pressure seals 15, 18.

Based on the above, it can be argued that the proposed construction of a crane with a valve handle position monitoring unit provides or turns off the water supply to the flexible pipeline with simultaneous generation of electrical information signals and transmission of these signals through external fire automatics (signaling) circuits.
