The suction type smoke detection technology is an important technology for fire prevention among large road maintenance mechanical equipment machinery, and is mainly characterized in that the smoke feeling is changed from passive to active, and whether smoke and fire appear in the equipment can be quickly perceived through the suction of fixed-point smoke.

Existing suction type smoke detectors typically include only a smoke collector and a detector host in communication via a hose. The smoke collector is arranged at a designated fire monitoring point, and negative pressure is generated by a negative pressure fan in the detector main machine, so that negative pressure is formed inside the smoke collector. When smoke is generated due to the occurrence or imminent occurrence of fire at the fire monitoring point, the smoke is sucked into the smoke collector due to negative pressure, and then flows into the detector host after passing through the smoke collector. When smoke is sensed to enter by a smoke sensing unit in the detector host, an alarm can be immediately sent out and indicated by an alarm indicator lamp.

However, the current smoke flow speed in the smoke collector is too slow, so that the alarm is delayed, the fire of a smoke detection point between machines cannot be timely alarmed, and the safety is not high enough.

Based on the problems, the utility model provides the high Wen Daoliu suction-type smoke detector, the smoke entering the smoke collector is guided by adding the guide rod, so that the flow speed of the smoke in the smoke collector is improved, the response speed of smoke sense is greatly improved, the fire alarm of a smoke detection point is more timely and effective, the requirements of large and medium-sized railway maintenance machinery on fire monitoring among machinery can be met, and meanwhile, the smoke detector is simple and reliable, stable in operation and long in service life.

The following detailed description of specific embodiments of the utility model refers to the accompanying drawings.

Referring to fig. 1, the present utility model provides a high Wen Daoliu inhalation-resistant smoke detector comprising: a smoke collector 100 having a plurality of suction ports 110 formed on a side wall thereof, configured to collect smoke of fire monitoring points; at least one deflector rod 200 located within the smoke collector 100 configured to direct smoke out of the smoke collector 100; a detector main body 300, which is communicated with the smoke collector 100, is configured to suck the smoke flowing out of the smoke collector 100 and give out a fire alarm.

Specifically, referring to fig. 2, the smoke collector 100 is of a hollow structure, one end of the smoke collector is closed, the other end of the smoke collector is open, and the open end holds smoke to flow out of the smoke collector 100. The side wall of the smoke collector 100 is provided with a plurality of suction holes for sucking smoke of fire monitoring points. In this embodiment, the smoke collector 100 has a hollow cylindrical structure.

In actual use, the smoke detector 100 is located remotely from the detector main body 300, so that the smoke detector 100 and the detector main body 300 may be connected by some means, such as a hose, which may be in communication with each other. In this embodiment, the smoke collector 100 is in communication with the detector host 300 via a hose 400, one end of the hose 400 is in communication with the smoke collector 100, and the other end is in communication with the detector host 300.

The plurality of flow guide rods 200 may be provided, and the plurality of flow guide rods 200 may be disposed in the smoke collector 100 in parallel, or may be disposed in the smoke collector 100 after being sequentially connected; the number and the manner of the specific arrangement of the guide rods 200 may be determined according to the actual situation, and are not limited herein. Referring to fig. 2, in this embodiment, only one guide bar 200 is provided.

In one aspect, when the cross-sectional area in the smoke collector 100 is fixed, the cross-sectional area through which smoke actually flows can be reduced by adding the flow guide rod 200, and when the negative pressure applied by the negative pressure device in the detector main unit 300 is fixed, the smaller the cross-sectional area through which smoke actually flows, the faster the flow speed of the smoke in the smoke collector 100 is, so that the smoke can flow into the detector main unit 300 communicated with the smoke collector 100 more quickly. When smoke is sensed by smoke sensing unit 342 in detector host 300, an alarm is immediately raised and indicated by an alarm indicator light. Thus, by using the deflector rod 200, the smoke can reach the detector host 300 faster and more quickly, the response speed is faster, the alarm time is shorter, the fire detection speed is faster, and the safety is higher.

On the other hand, the flow guide rod 200 may serve as a flow guide for smoke entering the smoke collector 100, and may guide the smoke more quickly along the flow guide rod 200 into the detector main unit 300.

In addition, the setting of guide bar 200 for dust or impurity granule in the smog can adhere to on guide bar 200, and then makes the volume of adhering to dust and granule on the smog collector 100 inner wall significantly reduced, can reduce the frequency that smog collector 100 changed, prolongs the life of smog collector 100.

Further, the smoke collector 100, the guide rod 200 and the hose 400 are made of high-temperature-resistant metal materials, so that the smoke collector is suitable for long-term operation in a high-temperature environment, has long service life, does not need frequent replacement of equipment, and has higher cost performance.

In specific implementation, the smoke collector 100 is installed at a designated fire monitoring point, and negative pressure is generated by the negative pressure fan 341 in the detector main unit 300, so that negative pressure is formed in the smoke collector 100, and then gas at the monitoring point is sucked. If smoke is present, it is quickly sucked into the smoke collector 100 and is sent into the detector main body 300 through the deflector rod 200 and the hose 400. The smoke collector 100 is installed inside the machinery room and is made of a high-temperature-resistant metal material.

The deflector rod 200 is installed in the smoke collector 100, and serves to increase the gas flow rate and speed up the gas reaching the detector main body 300. The guide bar 200 is made of a high-temperature-resistant metal material.

The detector main body 300 receives the smoke collected by the smoke collector 100 through the hose 400, and if the smoke reaches the smoke sensing unit 342 in the detector main body 300, the detector main body 300 gives a fire alarm. The smoke detector host 300 itself has a function of monitoring whether the smoke sensing unit 342 and the negative pressure fan 341 are operating normally, and provides an alarm. The smoke detector host 300 is mounted outside the machinery space.
