Disconnector-announcer (options)

The technical solution relates to fire fighting equipment, namely, to a fire alarm.

The prior art thermally activated disconnector according to p. RF No. 2183488, taken as a prototype. The thermally activated disconnector consists of two brackets with two legs. The tensile force acting on the brackets is symmetrically decomposed as a parallelogram of forces and disconnects both brackets in an emergency. The brackets are held in a fixed position by a thermally disconnecting element, preferably made in the form of a glass ampoule. The latter is held mainly perpendicular to the direction of extension between two opposite legs of both brackets. The other two legs of each bracket that do not support or do not hold the glass ampoule are connected to the ampoule holding leg of the other bracket with a geometric closure against the direction of extension, preferably with hooks. This connection with a geometric closure in case of emergency is disconnected as a result of the destruction of the glass ampoule. This design of the disconnector increases the reliability of its operation in an emergency.

A disadvantage of the known technical solution is the inability to monitor from the control panel whether the device has worked or not, and to disconnect in case of emergency situations.

The objective of the proposed utility model is such an improvement of the device that it fulfills the function of a notification in accordance with the requirements of fire tactics and makes it possible to remotely disconnect from a fire station. disconnect the mechanical lock of the cable induction device

of the deluge valve and ensure the transfer of the fire notification to the fire station, and also, in the event of an emergency, the disconnector-detector must disconnect the mechanical lock of the cable inducement device of the deluge valve under the influence of an electric signal supplied from the fire station.

The problem is solved by the claimed variants of the utility model. One of the options is characterized in that the disconnector detector contains two oppositely spaced mechanically interconnected staples that are subjected to tensile forces and between which a glass bulb filled with a heat-sensitive liquid is held perpendicular to the direction of stretching; said brackets are made in the form of half rings, with one of the ends of each half ring narrowed and bent inward parallel to the axis of tension, then bent to the outside, and at the other end of each half ring there is a window, while in a fixed position each narrowed and bent to the outside side of one a half-ring enters the window of another half-ring, each half-ring being held along the axis of tension by an earring having holes for connection with the half-ring and a tensile element and a L or T-shaped protrusion; additionally there is a board, on one side of which a hole is made, and on the opposite side there is a groove closed by an electrically conductive jumper into which the aforementioned Г- or Т-shaped protrusions of the corresponding earrings are inserted, while the terminal has an alarm loop device and a terminal block forming a serial electric circuit . Additionally, a thermal relay can be installed on the board parallel to the terminal device of the alarm loop.

Another solution to the problem posed is a detector-disconnector, which contains two oppositely spaced mechanically interconnected staples, which are subjected to tensile forces and between which are perpendicular

2 the direction of stretching is kept glass bulb filled

thermosensitive fluid; said brackets are made in the form of half rings, with one of the ends of each half ring narrowed and bent inward parallel to the axis of tension, then bent to the outside, and at the other end of each half ring there is a window, while in a fixed position each narrowed and bent to the outside side of one the half-ring enters the window of the other half-ring, each half-ring being held along the axis of tension by the earring, I have it; there are openings for connecting it to the half-ring and the tensile element and a L or T-shaped protrusion; additionally there is a board, on one side of which a hole is made, and on the opposite side, a groove closed by an electrical conductive jumper is made, into which the aforementioned Г- or Т-shaped protrusions of the corresponding earrings are inserted, while the terminal has an alarm loop device and a terminal block forming a serial electrical circuit, in addition, an additional heater and another terminal block are installed, forming another sequential electrical circuit. Additionally, in this embodiment, a thermal relay can be installed that is connected in parallel with the terminal device of the alarm loop.

3 FIG. 4 is a circuit diagram of an embodiment of a detector disconnector shown in FIG. 2.

The disconnector-detector (options, Fig. 1, 2) contains two identical brackets 1, between which a glass flask 2 is held in a known manner, each bracket 1 is made in the form of a half ring, while the end A of the half ring is narrowed and bent inward parallel to the tension axis, then bent to the outside, and at the opposite end of the half-ring there is a window 3, into which the portion of the end A of the other half-ring bent into the outer side enters. Each bracket 1 is held along the tension axis by an earring 4, which is available; it has a hole 5 for connecting with a half ring, a hole 6 for connecting with a pull ring; it has an element (not shown) and a L or T-shaped protrusion 7. Additionally there is a side plate 8, having a hole 9 on one side and a groove 10 on the opposite side, closed by an electrically conductive jumper 11. A hole 9 and a groove 10 are located along the tension axis of the device. The electrical jumper 11 is a contact connected in a known manner to an alarm loop terminal device 12 and a terminal strip 13 mounted on the board 8 and forms a serial electric circuit with them.

In the embodiment of FIG. 2, on the board 8, in addition, an electric heater 15 is installed, made, for example, in the form of an ohmic resistance, and another terminal block 16, forming another serial electrical circuit.

Additionally, in both versions (Fig. 1, 2), a thermal relay 14 can be installed on the board 8 parallel to the terminal device 12 of the alarm loop.

The embodiment of the detector disconnector shown in FIG. 1, works as follows. When the ambient temperature rises, the glass bulb 2 filled with a thermosensitive liquid heats up and, having reached the response temperature, collapses, the ends A of brackets 1 made in the form of half rings under tensile forces exerted by the tensile element (for example, a cable inducing device),

exit the windows 3, the half rings diverge in opposite directions, the Shaped protrusion 7 of the corresponding earring 4, leaving the groove 10, tears the conductive jumper 11, which is a contact (SQ1), connected in a known manner to the terminal device 12, and a notification of the operation of the cable inducement device through the terminal strip 13 enters the alarm loop.

The embodiment of the detector disconnector shown in FIG. 2, works similarly to the above, but thanks to the presence of an electric heater and another terminal block forming another serial electrical circuit, it is possible to control the disconnection of the device from the fire station. In this case, the electric signal supplied from the post enters through the terminal 16 to the heater 15, which heats the glass flask 2, causing its destruction. After such a forced destruction of the flask 2, the device is disconnected and a notification is received in the alarm loop as described above.
