Abstract
The utility model discloses an automatic alarm fire extinguisher, comprising a container for holding a fire extinguisher body, a fire extinguisher nozzle on the upper part of the container and a distance piece for controlling the opening and closing of the fire extinguisher nozzle. The automatic alarm fire extinguisher is characterized by also being provided with a shape memory alloy spring, a piezoelectric ceramic piece and an alarm, wherein the distance piece is installed in the fire extinguisher nozzle in a left and right sliding manner, when the distance piece is completely located in the fire extinguisher nozzle, the distance piece forms a sealed space with the fire extinguisher nozzle and the container, one of the left and right ends of the distance piece is connected with the shape memory alloy spring while the other end of the distance piece is connected with the piezoelectric ceramic piece, and the piezoelectric ceramic piece is serially connected with the alarm. The automatic alarm fire extinguisher disclosed by the utility model is simple in structure, has a reusable property and is capable of quickly monitoring fire, automatically entering a fire extinguishment state and sending an alarm in time to quickly carry out fire extinguishment work so as to effectively reduce the loss.
Description
Technical field
The utility model belongs to fire-fighting equipment field, relates to a kind of automatic alarm fire-extinguisher, is specifically related to a kind of automatic alarm fire-extinguisher based on marmem and piezoelectric ceramics.
Background technology
Warehouse is the place with fire disaster hidden danger, in warehouse, stores has inflammability mostly, Warehouse Fire has easy generation, the difficulty that easily spreads, puts out a fire to save life and property, lose the features such as large, during breaking out of fire, fire spreading is fast, cause firefighter to have little time to enter scene of fire, in warehouse, fire-fighting equipment can not get effective use, causes serious economic loss; According to statistics, Warehouse Fire generating capacity accounts for 10 left and right of annual fire generation total amount.
Fire extinguisher practical in fire-fighting at present has various ways, common are manually and automatic two large classes.Conventionally Automatic Fire Extinguisher adopts the structure of warning system and fire extinguishing system separate type, with low-melting alloy, seals nozzle, and when metal molten, extinguishing chemical sprays automatically, realizes fire extinguishing; Another additional a set of warning circuit with temperature-sensitive element, realizes automatic alarm.But there is complex structure, not compact, high in cost of production problem in this equipment.
Some technical schemes have been there are at present, solved to a certain extent above-mentioned technical problem, for example application number is: the automatic alarm fire-extinguisher > > that 200420030397.0 utility model patent < < memory drives, adopt exactly the memory effect of memorial alloy, reach automatic alarm fire-extinguishing function concurrently, but this scheme also has the following disadvantages:
(1) also there is complex structure in this scheme, problem with high costs;
(2) this scheme can not be reused, and causes the wasting of resources.
So, on market, in the urgent need to a kind of simple in structure, automatic alarm fire-extinguisher that can reuse, can monitor rapidly the condition of a fire, automatically enter fire extinguishing state, and give the alarm in time, impel carrying out rapidly of fire-fighting work, effectively reduce the loss.
Summary of the invention
This use is novel in order to solve above-mentioned technical problem, has proposed a kind of simple in structure, automatic alarm fire-extinguisher that can reuse.
The technical scheme that the utility model adopts is: a kind of automatic alarm fire-extinguisher, the container that comprises splendid attire fire extinguisher, be arranged on the fire extinguisher spout on described container top, control the partition of fire extinguisher spout switch, it is characterized in that: described automatic alarm fire-extinguisher is also provided with shape memory alloy spring, piezoelectric ceramic piece and alarm, described partition can be arranged in described fire extinguisher spout slidingly, when described partition is positioned at described fire extinguisher spout completely, with described fire extinguisher spout, container forms confined space, described one end, two ends, partition left and right is connected with described shape memory alloy spring, the other end is connected with described piezoelectric ceramic piece, described piezoelectric ceramic piece and described alarm are connected in series.
As preferably, described shape memory alloy spring is also provided with installation, and described shape memory alloy spring is arranged in described mounting cylinder, and one end is fixed on described mounting cylinder inwall.
As preferably, the memorial alloy that described shape memory alloy spring is selected is that TiNi is that marmem, copper base system marmem or iron-based are marmem, the recovery temperature of different marmems is different, for different places, can take different shapes memorial alloy, thereby reach best fire fighting effect, this has also increased this and has used novel range of application.
With respect to prior art, the utility model is a kind of simple in structure, automatic alarm fire-extinguisher that can reuse, and can monitor rapidly the condition of a fire, automatically enters fire extinguishing state, and gives the alarm in time, impels carrying out rapidly of fire-fighting work, effectively reduces the loss.
Accompanying drawing explanation
Fig. 1: the section of structure of the utility model embodiment.
The specific embodiment
Below with reference to specific embodiments and the drawings, the utility model is further elaborated.
Ask for an interview Fig. 1, the technical scheme that the utility model adopts is: a kind of automatic alarm fire-extinguisher, the container 1 that comprises splendid attire fire extinguisher, be arranged on the fire extinguisher spout 2 on container 1 top, control the partition 3 of fire extinguisher spout 2 switches, shape memory alloy spring 4, piezoelectric ceramic piece 5, the mounting cylinder 7 of alarm 6 and shape memory alloy spring 4, partition 3 can be arranged in fire extinguisher spout 2 slidingly, when partition 3 is positioned at fire extinguisher spout 2 completely, with fire extinguisher spout 2, container 1 forms confined space, partition 3 one end, two ends, left and right are connected with shape memory alloy spring 4, the other end is connected with piezoelectric ceramic piece 5, shape memory alloy spring 4 is arranged in mounting cylinder 7, one end is fixed on mounting cylinder 7 inwalls, piezoelectric ceramic piece 5 is connected in series with alarm 6.
The memorial alloy that the shape memory alloy spring 4 of the present embodiment can be selected is that TiNi is that marmem, copper base system marmem or iron-based are marmem, the recovery temperature of different marmems is different, for different places, can take different shapes memorial alloy, thereby reach best fire fighting effect, this has also increased this and has used novel range of application.
The utility model can be arranged on each place needing, warehouse for example, when warehouse breaking out of fire, environment temperature rises rapidly, while meeting or exceeding the recovery temperature of marmem, there is deformation in shape memory alloy spring 4, stretch elongatedly, partition 3 is pushed open, the interior extinguishing chemical of container 1 relies on the ejection of tank internal pressure, spray to comburant, realize fire-extinguishing function concurrently.At shape memory alloy spring 4, push a flash of switch open, partition 3 is exerted pressure to piezoelectric ceramic piece 5, and generation current excites alarm 6 to give the alarm, and impels administrative staff to take fire fighting measure.When the condition of a fire is removed, environment temperature declines gradually, and when temperature is during lower than the recovery temperature of marmem, shape memory alloy spring 4 can shorten chaps, and partition 3 is retracted to normal position, and fire extinguisher quits work.This measure can reduce the use of extinguishing chemical and realize the automation of fire-extinguisher cock.
These are only preferred embodiment of the present utility model; be not intended to limit protection domain of the present utility model; therefore, all any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
