Abstract
The invention relates to a fire hydrant burglar alarm device capable of alarming in time, which adopts function characteristics of a fire hydrant automatic fire alarm system as follows: firstly, an alarm signal line is broken at the front end of a handle button of a fire hydrant, a travel switch and a power-off delay reset switch are connected in series, the travel switch is installed on a door frame of a fire hydrant box, when a box door is opened, the power-off delay reset switch works, and when the power-off delay reset switch works, a handle button line is disconnected, i.e. the fire hydrant burglar alarm device alarms; secondly, the handle button line of the fire hydrant is connected in parallel with temperature and smoke fire detectors with addresses, an alarm signal line is disconnected, the travel switch is connected in series and installed on the door frame of the fire hydrant box, and when the box door is opened, the travel switch works to disconnect the alarm signal line, i.e. the fire hydrant burglar alarm device alarms; or thirdly, the heat fire detector with the address is connected in parallel with the handle button line of the fire hydrant, a temperature sensing thermal resistor in the heat fire detector is replaced by the travel switch, the travel switch is installed on the door frame of the fire hydrant box, and when the door is opened, the travel switch switches on the heat fire detector, i.e. the fire hydrant burglar alarm device alarms.
Description
Affiliated technical field
Fire prevention field under the present invention.
Background technology
In residential quarters, hydrant is stolen, and while causing fire, fire fighting device can not drop into fire extinguishing, and the hydrant fire extinguishing system generally can not normally be used, and is difficult to for these years solve.Because of hydrant be arranged in buildings distribute very wide, the Property Management of residence difficulty is large, hydrant assembly hydraulic giant, water band, aluminium connect and buckles, copper bolt core etc. opened chamber door and is easy to stolenly, and it is antitheft to lock at chamber door in some community, and when fire is arranged, hydrant can't come into operation.
Summary of the invention
Three of fire hydrant burglar alarm device designs of the present invention solve real row:
1. the present invention utilizes the functional characteristic of hydrant automatic fire alarm system, and when fire alarm is arranged, in fire hydrant box, hand push button starts fire pump and reports to the police, and when fire-fighting manual pull station circuit disconnects, the automatic fire control alarm host machine shows address fault.Disconnect a travel switch of series connection and a special time-delay reset switch at the moving alarm linkage wire of fire-extinguishing box Internal handle, when the chamber door travel switch on-delay switch motion that is opened reports to the police.
2. heat fire detector is in automatic fire alarm system, and when fire is arranged, heat detection thermistor resistance raises and changes with temperature, and when prevention reaches certain value, circuit turn-on sends the address fire alarm.Utilize this functional characteristic to install a temperature sensing fire alarm detector additional in fire hydrant box, the thermistor in heat detector is replaced with to a travel switch, when the chamber door travel switch that is opened is connected heat detector and reported to the police immediately.
3. heat detector or smoke detector are in automatic fire alarm system, fault alarm when circuit disconnects, utilize this function to install a heat detector or smoke detector, travel switch of series connection additional in fire hydrant box, when the hydrant chamber door is opened, travel switch disconnects and reporting to the police.
Embodiment
1. the present invention enters interlock hand push button wire negative pole one termination in fire hydrant box the common port of stroke switch, and the normally closed point of the other end of travel switch is connected with the power cathode contact of time-delay reset switch.The anodal disconnection of hydrant hand push button signal wire, the electric wire two ends connect respectively other two wires of delay switch.When the fire hydrant chamber door is closed, travel switch disconnects, and the time-delay reset switch quits work.When the hydrant chamber door is opened, travel switch is connected, the delay switch action disconnects hand push button signal line positive pole, now alarm host machine shows that address fault or hydrant chamber door are opened, reach the theft protection purpose, now time-delay reset switch time delay automatically reset after 30 seconds, and the fire automatic alarm control system recovers normal operation.This invention theft protection alarm is not limited by producer's product or brand, install and simply do not need technological debugging, time-delay reset switch power acquisition does not need separately to establish power supply with fire-fighting automatic alarm direct current signal power supply in one, does not disturb alerting signal, in off-position, does not work at ordinary times.When the hydrant come into operation is installed additional to the theft protection warning device, because of fire hydrant box doorframe inner structure difference, at the fire hydrant box doorframe, travel switch fixing metal web joint is installed, note the contact angle of travel switch and hydrant chamber door, when closing the hydrant chamber door, travel switch should move off delay reset switch power supply.While finishing when reporting to the police, the fire protection warning main frame should reset in time.
2. the present invention is arranged on heat fire detector in fire hydrant box, heat detector warning wire and hand push button circuit are connected in parallel, thermistor in heat detector is changed to travel switch, travel switch is arranged on fire hydrant box doorframe limit, hydrant chamber door shutoff stroke switch disconnects at ordinary times, open travel switch connection heat detector when the hydrant chamber door and report to the police, can find in time to steal hydrant.This invention heat detector must be same producer product or identical with alarm host machine signal transmission agreement, and other products can not be general.Simple heat detector is installed in above invention only needs the address detail programming, and heat detector is in the warning armed state at ordinary times.When the hydrant come into operation is installed additional to the theft protection warning device, when the fire hydrant box doorframe is installed fixed journey system switch metallic interconnect, note travel switch and hydrant chamber door contact angle, when closing the hydrant chamber door, travel switch should disconnect, and makes heat detector in the alarm condition of awaiting orders.After finishing when reporting to the police, the fire protection warning main frame should reset in time.
3. the present invention is arranged on temperature-sensitive or smoke fire detector in fire hydrant box, two wires of temperature-sensitive or smoke detector are connected in parallel in the hand push button alarm circuit, between the line of hand push button and temperature-sensitive or smoke fire detector, disconnect a wherein wire, the travel switch series connection is arranged on the fire hydrant box doorframe in the line, Door for fire hydrant shutoff stroke switch connection at ordinary times, temperature-sensitive or smoke fire detector are in the alarm condition of awaiting orders, when the hydrant chamber door is opened, travel switch action fire detector line is disconnected warning, can find in time to steal hydrant.This invention heat fire detector must be same producer product or identical with alarm host machine signal transmission agreement with automatic fire alarm system, and other products can not be general.Fire detector needs the address detail programming after installing, when the fire hydrant box doorframe is installed travel switch, closing hydrant chamber door limit switch contact should connect with temperature-sensitive or smoke fire detector circuit, fire detector is in the warning armed state, and finishing the fire protection warning main frame when reporting to the police should reset in time.
