Abstract

The utility model discloses an over-standard-concentration coal gas exhaust system which comprises an indoor carbon monoxide gas detector, a wireless transmitter and at least one wireless receiver. The carbon monoxide gas detector is used for monitoring the coal gas concentration inside a room, and when the coal gas concentration in the room is higher than the preset value, the carbon monoxide gas detector sends signals to the wireless transmitter. The wireless transmitter is used for sending induction signals to the wireless receiver in each room. The wireless transmitter is electrically connected respectively with an exhaust fan and an alarm device, and when the wireless receiver receives induction signals sent by the wireless transmitter, the wireless receiver sends out control signals to control the exhaust fan to exhaust the air and the alarm device to send alarms. The exhaust system monitors the concentration of carbon monoxide generated by the burning coal in the room, and once the concentration excesses the safety standard, the alarm device and the exhaust system can be started through the wireless transmitter and the receiver to alarm the relevant persons and to exhaust toxic gas to the outside, thereby ensuring the life safety of the people.

Description

The gas concentration gas extraction system that exceeds standard

Technical field

The utility model relates to the gas concentration gas extraction system that exceeds standard.

Background technology

In the many places of China, winter, people's general custom was closed door and window burning stove, a heatable brick bed that the make a fire heating of household, had the danger of carbon monoxide (coal gas), also often poisoned because of concentration over-standard.In these carbon monoxide (coal gas) poisoner, existing inhabitation one-storey house (building) also has the city dweller with the outskirts of a town resident and the nonlocal civilian worker of coal stove for heating, and do not know seize how many people's life because of gas poisoning takes place every year.Coal-fired carbon heating in winter, gas poisoning hidden danger is big, and this is minimum general knowledge.But if some safe facilities can be arranged, the generation of tragedy still is avoidable.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of gas concentration gas extraction system that exceeds standard is provided.

For realizing above purpose, utility model has been taked following technical scheme: a kind of gas concentration gas extraction system that exceeds standard, include and be arranged at indoor carbon monoxide gas bulk detector, transmitting set, at least one wireless receiver, the carbon monoxide gas bulk detector, it is used to monitor indoor gas concentration, and when indoor gas concentration surpasses preset value, this carbon monoxide gas bulk detector sends signal to transmitting set; Transmitting set, it is electrically connected with the carbon monoxide gas bulk detector, and the wireless receiver that is used in being arranged on each room sends induced signal; Wireless receiver, it is electrically connected with scavenger fan, alarm respectively, and when this wireless receiver received the induced signal that described transmitting set sends, wireless receiver sent control signal, the exhaust and the alarm equipment alarm of control scavenger fan.

The utility model compared with prior art, has following advantage: utilize carbon monoxide (coal gas) sensor, constantly monitor carbon monoxide (coal gas) concentration that indoor coal burning carbon produces, in case surpass safety standard, promptly start alarm device and gas extraction system by wireless transmission and receiving system, the caution relevant personnel also discharge toxic gas outdoor simultaneously, guarantee life security.

Description of drawings

Fig. 1 is the utility model system block diagram.

The specific embodiment

Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.

Embodiment:

See also shown in Figure 1, a kind of gas concentration gas extraction system that exceeds standard, include and be arranged at indoor carbon monoxide gas bulk detector, transmitting set, four wireless receivers, it is separately positioned in four rooms, the carbon monoxide gas bulk detector, and it is used to monitor indoor gas concentration, when indoor gas concentration surpasses preset value, this carbon monoxide gas bulk detector sends signal to transmitting set; Transmitting set, it is electrically connected with the carbon monoxide gas bulk detector, and the wireless receiver that is used in being arranged on each room sends induced signal; Wireless receiver, it is electrically connected with scavenger fan, alarm respectively, and when this wireless receiver received the induced signal that described transmitting set sends, wireless receiver sent control signal, the exhaust and the alarm equipment alarm of control scavenger fan.

In the present embodiment, this carbon monoxide gas bulk detector adopts has very high sensitivity and good selective gas sensor to carbon monoxide, can be applied to the carbon monoxide sniffer of family, environment/the be suitable for detection of carbon monoxide, coal gas etc.

Be specially: power lights: green light, light after the energising, extinguish during warning; Alarm lamp: red light, light during warning, extinguish when stopping to report to the police; Connect power supply, after green light lighted or glimmered 3 minutes, alarm began operate as normal; When the gas that is detected reached alarm point, alarm began to report to the police, and green light extinguishes, alarm lamp lights, buzzer sends " B, B, B ... " chimes of doom, when the concentration of the gas that detects drops to alarm point when following, alarm then stop to report to the police (carbon monoxide is reported to the police delay function); Present embodiment has increased connection exhaust fan function, and when alarm equipment alarm, the exhaust fan that has connected begins to start, and gets rid of pernicious gas automatically; Can also increase connection manipulator or magnetic valve function, when alarm equipment alarm, manipulator that has connected or magnetic valve can be closed gas valve automatically, thereby cut off harmful source of the gas.

Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
