Abstract
The utility model discloses an automatic fire fighting alarm which is characterized in that a shell (1) is arranged on the utility model, a break back contact (7) is arranged on the shell and is connected with the circuit of the alarm, corresponding to the break back contact (7), a moving contact (6) is arranged and is fixed on the end of a driving rod (8), an offset spring (3) is sleeved on the driving rod (8) in the interior of the shell (1), a memory spring (4) is sleeved the end of the driving rod (8)the exterior of the shell (1), the bottom of the memory spring (4) is connected with an adjusting nut (5) arranged on the driving rod (8). The utility model has the advantages of few parts, simple structure, stable performance and high sensitivity, and traditional sensitive components are replaced by the alloy with shape memory.
Description
Technical field:
The utility model relates to a kind of alarm, especially a kind of high sensitivity, responds fire-fighting autoalarm rapidly.
Background technology:
The critical component of fire protection warning device is a fire detector, and its sensitivity and response speed are to judge the important indicator of alarm quality.Fire detector commonly used at present mainly contains temp sensing type and feels two kinds of cigarette formulas.The senser of heat detector adopts bimetal leaf or low-melting alloy usually, and wherein the movable stroke of bimetal leaf is little, can only do two dimensional motion, and response speed is slower.Low-melting alloy then is disposable use, and cost performance is lower.Smoke detector is to utilize the light-proofness of smog to detect the concentration of smog, structure more complicated, cost height.
Summary of the invention:
The utility model provides a kind of knot enough simple at the deficiencies in the prior art, can use the temp sensing type fire-alarm of dependable performance repeatedly.
Technical solution of the present utility model is: a kind of fire-fighting autoalarm, it is characterized in that: be provided with housing 1, it is provided with fixed contact 7, fixed contact 7 is connected with warning circuit, and with the fixed contact 7 corresponding moving contacts 6 that are provided with, moving contact 6 is fixed on drive rod 8 ends, on the drive rod 8 of housing 1 inside, be with bias spring 3, be with memory spring 4 on the drive rod 8 of housing 1 outside, the bottom of memory spring 4 and adjusting nut 5 join, and adjusting nut 5 is arranged on drive rod 8 bottoms.
Be fixedly connected with spring leaf 2 with described drive rod 8, it is arranged on the below of fixed contact 7.
It is few to the utlity model has parts, simple in structure, stable performance, advantages such as sensitivity height.Adopt marmem to substitute traditional senser, its principle is that memory alloy element extends automatically when ambient temperature has reached the memorial alloy rated temperature, promotes drive rod and moves, and makes the normally opened contact closure, and circuit is connected, and sends alarm signal.When ambient temperature was lower than phase transition temperature, memory alloy element shrank, and the contact is disconnected, and stopped to report to the police, thereby reached the purpose that constant temperature is reported to the police.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, a kind of fire-fighting autoalarm, it is characterized in that: be provided with housing 1, it is provided with fixed contact 7, and fixed contact 7 is connected with warning circuit, with the fixed contact 7 corresponding moving contacts 6 that are provided with, moving contact 6 is fixed on the drive rod 8, is with bias spring 3 on the drive rod 8 of housing 1 inside, is with memory spring 4 on the drive rod 8 of housing 1 outside, the bottom of memory spring 4 and adjusting nut 5 join, and adjusting nut 5 is arranged on drive rod 8 ends.
Be fixedly connected with spring leaf 2 with described drive rod 8, it is arranged on the below of fixed contact 7.When the power on acting on spring leaf 2 reached critical force, spring leaf 2 is upset rapidly, accelerated quiet, moving contact in conjunction with speed, the formation quick-acting mechanism.
During work, alarm being placed test environment, the current circuit that is made of battery, electric bell, moving contact 6 and fixed contact 7 is set, is normally opened contact at ordinary times, and circuit is open circuit, does not report to the police.In case (as 70 ℃) memory spring 4 was subjected to thermal stretching when ambient temperature reached rated temperature, overcame the bias force of bias spring 3, promote drive rod 8 ends and move down, make the normally opened contact closure, circuit is connected, and sends alarm signal.When temperature was lower than design temperature, memory spring 4 shrank, and the contact disconnects, and stopped to report to the police, and so repeatedly, realized the constant temperature warning, reusable up to ten thousand times.
Claims (2)
1. fire-fighting autoalarm, it is characterized in that: be provided with housing (1), it is provided with fixed contact (7), fixed contact (7) is connected with warning circuit, the corresponding moving contact (6) that is provided with fixed contact (7), moving contact (6) is fixed on drive rod (8) end, on the inner drive rod (8) of housing (1), be with bias spring (3), on the outside drive rod (8) of housing (1), be with memory spring (4), the bottom of memory spring (4) and adjusting nut (5) join, and adjusting nut (5) is arranged on drive rod (8) bottom.
