Description

Double-temperature composite sensing fire detector

Technical field

The present invention is mainly concerned with fire detection equipment field in the fire control equipment, refers in particular to a kind of double-temperature composite sensing fire detector.

Background technology

In the existing fire detection equipment, generally can only survey the gas flow temperature in testee or the space singlely, when temperature surpasses setting value, send fire signal.But in present complex apparatus or space, the hidden danger of fire is existing might to be the fire hazard that internal fault causes, the danger that also has outside fire to cause.When internal fault causes fire hazard, generally show as shell temperature in advance and raise; When outside fire took place, heat was generally come by convection current or radiation delivery, and shell temperature rises very slow relatively, surveys difficulty.Such as equipment such as transformer, oil tank or cables, its device interior heating accident shows that mainly shell temperature raises, in case surpass the temperature range that can bear, so all might cause very big loss.Therefore, how can simultaneously testee body surface and air outside temperature be surveyed simultaneously, it is a problem of needing solution badly, and existing way generally is to adopt the method for arranging the different detectors of two-way, and its shortcoming is: complex structure, cost height, installation bother, safeguard inconvenience etc.

Summary of the invention

The problem to be solved in the present invention just is: at the technical matters that prior art exists, the invention provides a kind of simple in structure, volume is little, with low cost, easy for installation, the double-temperature composite sensing fire detector that can survey testee body surface and external air temperature simultaneously.

For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of double-temperature composite sensing fire detector, it is characterized in that: it comprises door, housing and guard shield box, be provided with a mandrel in the housing, be arranged with compression spring on the mandrel, one end of mandrel contacts with door, the other end is positioned at the guard shield box and is provided with touch panel, be equiped with in the guard shield box and be used for the binding post that cooperates with touch panel, the top and bottom of door and housing are located respectively, and symmetry offers through hole, be provided with in the through hole and be used for lower carriage and upper bracket that door and housing are kept in touch, one end of lower carriage and upper bracket is hook-shaped and links to each other with door, offer on the other end and being inserted with the fusing pin and the pin-and-hole of fusing pin down respectively, last fusing pin and fusing down sell respectively be installed in housing on last heat collecting sheet link to each other with following heat collecting sheet.

The described fusing-off temperature of going up fusing pin and following fusing pin material therefor can be identical or inequality.

Described housing one end contacts with door, and the other end extends in the guard shield box, is fixed on the guard shield box by bracing frame and set nut.

Also can further be equiped with the reinforcement plug in the described mandrel.

Compared with prior art, advantage of the present invention just is:

1, double-temperature composite sensing fire detector of the present invention, simple in structure, volume is little, with low cost, easy for installation, after the installation, can survey testee body surface and external air temperature simultaneously, thereby improve the overall security of warning device;

2, double-temperature composite sensing fire detector of the present invention, the fusing-off temperature of the last fusing pin and the pin material therefor that fuses down can be set respectively according to actual needs, can be identical, also can be inequality, so just can be according to surveying needs, different temperature alarming scopes is set neatly, has guaranteed detector sensitivity, improved its overall security.

Embodiment

Below with reference to the drawings and specific embodiments the present invention is described in further details.

As depicted in figs. 1 and 2, a kind of double-temperature composite sensing fire detector of the present invention, it comprises door 1, housing 2 and guard shield box 15, be provided with a mandrel 8 in the housing 2, be arranged with compression spring 7 on the mandrel 8, one end of mandrel 8 contacts with door 1, and the other end is positioned at guard shield box 15 and is provided with touch panel 13, and touch panel 13 is fixed on the mandrel 8 by screw 14.For intensity and serviceable life and the stability that improves mandrel 8, also can further be equiped with in the mandrel 8 and strengthen plug 11.Being equiped with first binding post 12 that is used for cooperating with touch panel 13 and second binding post, 20, the first binding posts 12 in the guard shield box 15 is installed on the mount pad 16 with second binding post 20 and links to each other with warning device.In the present embodiment, housing 2 one ends contact with door 1, and the other end extends in the guard shield box 15, are fixed on the guard shield box 15 by bracing frame 9 and set nut 10, fuse with guard shield box 15, keep the stationarity of single unit system.The top and bottom of door 1 and housing 2 are located respectively, and symmetry offers through hole 17, be provided with in the through hole 17 and be used for lower carriage 3 and upper bracket 18 that door 1 and housing 2 are kept in touch, one end of lower carriage 3 and upper bracket 18 is hook-shaped and links to each other with door 1, offer pin-and-hole on the other end, being inserted with fusing pin 5 and fusing pin 4 down in the pin-and-hole respectively, last fusing pin 5 and fusing down sell 4 respectively be installed in housing 2 on last heat collecting sheet 19 link to each other with following heat collecting sheet 6.Wherein, the fusing-off temperature of the last fusing pin 5 and pin 4 material therefors that fuse down can be set respectively according to actual needs, can be identical, also can be inequality, and in specific embodiment, the fusing pin also can be used replacements such as temperature-sensitive glass envelope simultaneously.

Principle of work: being installed on the equipment such as transformer, oil tank or cable with detector of the present invention is example, in normal operation, utilize lower carriage 3 and upper bracket 18 to hook door 1, door 1 is contacted with housing 2 and mandrel 8, it is fixing with the pin 4 that fuses down to use fusing pin 5 then, at this moment, mandrel 8 contracts in guard shield box 15 under the effect of door 1 thrust, compression spring 7 on the mandrel 8 is in impaction state, touch panel 13 on mandrel 8 other ends makes fire alarm installation be in off-state away from first binding post 12 and second binding post 20.

Heat collecting sheet 6 directly contacted with the body surface of transformer, oil tank or cable under following fusing pin 4 passed through, the induction shell temperature.When shell temperature reaches and surpass setting value, (reach when 4 fusing-off temperature is sold in fusing down), following fusing pin 4 fusing, lower carriage 3 and mandrel 8 eject forward under the restoring force effect of compression spring 7, make with mandrel 8 on touch panel 13 move forward, contact with second binding post 20 with first binding post 12, connect fire alarm installation, send fire alarm signal.

Last fusing pin 5 is by the airborne thermal current of last heat collecting sheet 19 inductions, when airborne hot stream temperature reaches and surpasses setting value (when reaching the fusing-off temperature of fusing pin 5), last fusing pin 5 fusing, upper bracket 18 and mandrel 8 are ejecting forward under the effect of compression spring 7 restoring forces, the touch panel 13 that is connected with mandrel 8 is moved forward, contact with second binding post 20 with first binding post 12, connect fire alarm installation, send fire alarm signal.At this moment, can be as required, the fusing-off temperature of last fusing pin 5 can be different with the fusing-off temperature of the pin 4 that fuses down.
