Abstract

The utility model relates to a liquefied gas leakage alarm, which mainly consists of an air balloon (1), a shell (2), a drag switch (3), a green indicator light (4), a red indicator light (5), a sound speaker (6) and a power plate (7), wherein, the green indicator light (4), the red indicator light (5) and the sound speaker (6) are arranged on the shell(2). The green indicator light is on when a switch (31) dragged by the air balloon is contacted with the contact b, and the red indicator light is on when the switch (31) is contacted with the contact a, and the sound speaker (6) synchronously make alarming sound to alarm. The utility model has the advantages of simple structure, low cost, and simple use, maintenance and repairing.

Description

The gas leak alarm

Technical field

Warning device when the utility model relates to a kind of gas leak refers to when gas leak the change with balloon sensing room air density especially, thereby drags the gas leak alarm of the switch activated caution light of small portable harmony sound.

Background technology

Liquefied gas has brought energy to the mankind, has enriched people's life, but on the other hand, also can bring on a disaster to people, the misfortune that the leakage of liquefied gas brings to people, people still have vigilance, all kinds of preventive measure and warning device are also a lot, structure more complicated all in general, cost is higher, and that how to design is simple in structure, cost is lower, maintenance and repair are also fairly simple, and this is that people look forward to, especially the listing of this class alarm is being expected in the suburb in small and medium-sized cities and city especially.

Summary of the invention

According to background technology, it is sensing element at indoor arrangement balloon that the purpose of this utility model is to provide a kind of, the indoor atmospheric density that changes owing to the leakage of liquefied gas of sensing, cause the suffered buoyancy of balloon to increase, thereby drag the switch activated warning lamp of small portable and the gas leak alarm of caution sound.

To achieve these goals, the utility model is realized according to following technical scheme:

A kind of gas leak alarm, mainly by balloon (1), housing (2) drags switch (3), green indicating lamp (4), red led (5), loudspeaker (6), power panel (7) is formed, wherein: on housing (2) outside surface, green indicating lamp (4) is installed, red led (5), portion is equipped with and drags switch (3), loudspeaker (6) within it; The switch (31) that drags switch (3) is enclosed within on the guide pillar (33), can drag switch (31) by balloon (1) slides up and down along guide pillar (32), switch (31) extreme position that makes progress when sliding can contact with a contact on the contact frame (34), extreme position can contact with the b contact downwards, is set with spring (33) on guide pillar (32).

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, the utility model adopts balloon to be sensing element, and is simple in structure, is quick on the draw, and switch activated air density values is adjusted by the pre compressed magnitude of spring, and is easy to use, safety;

2, the utility model adopts warning lamp and loudspeaker to send the dual warning of caution language that sets in advance, and has improved the fiduciary level of reporting to the police;

3, the utility model is simple in structure, and is light, and cost is low, and working service is repaired simple and easy.

Description of drawings

Fig. 1 is the utility model general structure front elevational schematic

Fig. 2 is the A-A cross-sectional schematic of the utility model Fig. 1

Among the figure: 1-balloon, 2-housing, 21-external power switch, 22-battery supply case, 23-battery power switch, 3-drags switch, 31-switch, 32-guide pillar, 33-spring, 34-contact frame, the 35-wiring board, 4-green indicating lamp, 5-red led, 6-loudspeaker, 7-power panel

Embodiment

By illustrated in figures 1 and 2, the utility model is mainly by balloon 1, and housing 2 drags switch 3, green indicating lamp 4, red led 5, loudspeaker 6, power panel 7 is formed, wherein, on housing 2 outside surfaces, green indicating lamp 4 is installed, red led 5, portion is equipped with and drags switch 3, loudspeaker 6 within it; The switch 31 that drags switch 3 is enclosed within on the guide pillar 33, can drag switch 31 by balloon 1 slides up and down along guide pillar 32, switch 31 extreme position that makes progress when sliding can contact with a contact on the contact frame 34, and downward extreme position can contact with the b contact, is set with spring 33 on guide pillar 32.

As seen from the figure, if during the indoor liquefied gas that does not have to leak, switch 31 of the present utility model contacts with contact b by deadweight, it is bright that this moment, circuit was connected green indicating lamp 4, this is the information of safety, in case it is indoor when liquefied gas is arranged, the density of air just changes, balloon 1 suffered buoyancy has just increased, and is enough to drag switch 31 and upwards slides along guide pillar 32, contacts disengagement with b is ordered, green light extinguishes, switch 31 contacts with a contact, and at this moment bright the and loudspeaker 6 of red led 5 sends caution sound, alarm equipment alarm.

As can be known, on the frame of contact, be installed with wiring board 35, the language memory chip is housed on it, can realize storage caution language.

External power switch 21 also is installed on housing 2, and power panel 7 is convenient to connect electricity and is used, if during short of electricity or other reasons do not have the dispatch from foreign news agency supply, can use the battery of installing in the battery supply casees of installing in the housing 2 22, open battery power switch 23 and can use.

Know that again how many times are the leakage rate of indoor liquefied gas reach and can start alarm, can adjust the pre compressed magnitude of spring 33 in advance and determine.

Claims
