Abstract
The utility model relates to a new fire danger alarm conducting wire which can detect fire danger. Copper cored plastic conducting wires with are small sections with a length of 20 cm to 100 cm are welded by fusible alloy to form a conducting wire. The welding points which are sealed by fusible insulating material are called fusible joints. The melting temperature of the fire danger alarm conducting wire has various standards and each standard is selected according to requirements. A plurality of fusible joints are distributed on each conducting wire. Both ends of the conducting wire are connected with a broken type alarm connector and a common pole. When fire danger happens, the fusible joints are broken because the outside temperature is raised. Audible and visual alarm is sent out by the electronic alarm. An automatic fire extinguisher can also be started up by the intermediate relay. The utility model has rapid alarm and low equipment cost.
Description
The utility model relates to a kind of new fire warning wire, the particularly a kind of many fusing points formula fire warning wire that can find out fire.Environment temperature rises to temperature control specification selected in 60 ℃～190 ℃ scopes during fire, can make electronic alarm the acousto-optic fire occur and report to the police, and also can start various automatic fire extinguishers by auxiliary reclay.
The fire warning wire of existing Britain development is to adopt bridge-type resistance temperature-sensitive principle, and environment temperature raises when fire, and changes the resistance in the warning wire.The variation of this resistance value is very small, must calculate micro-changes in resistance by electronic calculator, just can make alarm equipment alarm, this system architecture complexity, installation cost height.
The purpose of this utility model provides a kind of new many fusing points formula fire warning wire, and this warning wire is to adopt a copper-cored plastic wire, is cut into a lot of segments, welds (weld is at meltable joint) with fusible alloy again.Lead two termination disconnecting-type electronic alarms.Environment temperature raises when fire, meltable joint fusing, and the lead automatic cutout, circuit is obstructed, makes the disconnecting-type electronic alarm send fire and reports to the police.This lead is applicable to the electric fireproof engineering, can with cable, the parallel installation of various power lead, when electric wiring raises because of overload, short circuit temperature, can trigger the warning wire system alarm.This lead also can be applicable to occasions such as room, warehouse, open-air stockpile, and the control point is intensive, can report to the police rapidly, and simple structure, installation cost is cheap, small investment.
Task of the present utility model is finished in the following manner: by copper core cable in plastics; be cut into 20～100 centimetres of grades and need the segment of length specification; each segment copper-cored plastic wire one section one section ground of fusible alloy with the temperature of fusion specification of selecting in 60 ℃～190 ℃ scopes is welded;, anticreep in fusible alloy pad outside with protection solder joint alloy anticorrosion with meltable insulating material coating sealing.Its pad is meltable joint.The lead that is welded into like this, many fusing points formula fire warning wire.Two of this lead terminates on the binding post and utility pole of disconnecting-type electronic alarm, when fire takes place, environment temperature raises, make a nearest meltable joint fusing disconnection on many fusing points formula fire warning wire, effect by the disconnecting-type electronic alarm, send the acousto-optic fire and report to the police, also can start various automatic fire extinguishers by auxiliary reclay.The length specification (being the distance of meltable internode) that the copper-cored plastic wire of many fusing points formula fire warning wire is cut into segment is 20～100 centimetres etc., and its specification can be determined as required.The temperature of fusion of the fusible alloy of the meltable joint of this lead has various different sizes, and the temperature of fusion of the meltable insulating material of its coated sealing in outside is a little less than the fusible alloy temperature, so that fusible alloy can in time melt.The meltable joint warning of this lead temperature of fusion specification is selected as required.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1, the many fusing points that the utility model proposes formula fire warning wire structural drawing.
Fig. 2, the many fusing points that the utility model proposes formula fire warning wire connects figure with the disconnecting-type electronic alarm.
The lead of forming by copper core (1) and ambroin (2), be cut into 20-100 centimetre of grade and need the segment of length specification, with reference to Fig. 1, copper core (1) with each segment copper-cored plastic wire, fusible alloy (3) with the temperature of fusion specification of selecting in 60 ℃～190 ℃ scopes welds, the outside at fusible alloy pad (3) seals with meltable insulating material (4) coating, and this pad is meltable joint (5), and the lead that is welded into like this is many fusing points formula fire warning wire.Every many fusing point formula fire warning wire shown in Figure 2 (6), (7), (8) ... two ends are connected on the binding post a of disconnecting-type electronic alarm (10), f respectively; B, g; C, h; On, this lead (6), (7), (8) ... the centre be connected on by common wire (9) on the earthing pole n of disconnecting-type electronic alarm, this lead (6), (7), (8) ..., each is being controlled
#1,
#4;
#2,
#5;
#3
#6; Warehouse or room etc.Environment temperature raise when fire took place, make many fusing points formula fire warning wire (6), (7), (8) ... going up any one meltable joint (5) fusing disconnects, this lead and shared lead (9) are opened circuit, by the effect of disconnecting-type electronic alarm (10), send acousto-optic fire alarm signal.The distance of the meltable joint (5) of many fusing points fire warning wire has specification such as 20-100 centimetre, can select as required.The temperature of fusion that meltable joint (5) is gone up fusible alloy (3) has specifications such as 60 ℃～190 ℃.The temperature of fusion of the meltable insulating material of sealing (4) that the outside is coated is a little less than the fusible alloy temperature, so that fusible alloy can in time melt warning.The temperature of fusion specification of meltable joint is selected as required.
Claims (4)
1, a kind of copper-cored plastic wire that is cut into segment, by meltable joint (5) copper-cored plastic wire of each segment is welded into many fusing points formula fire warning wire, it is characterized in that of fusible alloy (3) welding of the copper core (1) of copper-cored plastic wire, seal with meltable insulating material (4) coating in the outside of fusible alloy (3) by selected temperature of fusion in the meltable joint (5).
2,, it is characterized in that fusible alloy (3) and meltable insulating material (4) form meltable joint (5) by the said many fusing points formula of claim 1 fire warning wire.
3, by claim 1,2 said many fusing points formula fire warning wires, the temperature of fusion specification that it is characterized in that the fusible alloy (3) in the meltable joint (5) is 60 ℃～190 ℃, selects as required.
