CN-224231101-U - Aircraft cabin temperature sensor pipeline cleaning device

Abstract

The utility model discloses a pipeline cleaning device for a temperature sensor of an aircraft cabin, which belongs to a special pipeline cleaning tool and comprises a supporting seat, wherein the supporting seat is used for being installed on an air outlet corresponding to the temperature sensor, a filter bag is sleeved on the supporting seat, the device further comprises a combined pipeline, the combined pipeline is used for being respectively communicated with an air inlet of the temperature sensor and an external air source, and the external air source is used for conveying air from the air inlet of the temperature sensor through the combined pipeline. The air inlet through outside pressurized gas by temperature sensor gets into, blows out the dust and the impurity of deposit in the pipeline to collecting in the filter bag by the gas outlet, and then need not to dismantle luggage rack and temperature sensor pipeline and can clear up its inside impurity, avoids the pipeline to block up and influences its temperature acquisition in the passenger cabin to showing the efficiency that has promoted temperature sensor clearance, reducing the time cost that the airline maintenance spent.

Description

Aircraft cabin temperature sensor pipeline cleaning device Technical Field The utility model relates to a special pipeline cleaning tool, in particular to a pipeline cleaning device for an aircraft cabin temperature sensor. Background The temperature sensor of the aircraft cabin is generally designed behind the luggage rack, dust and impurities are easy to deposit on an inner pipeline of the temperature sensor in the use process, so that the sensor pipeline is blocked, the acquisition of the cabin temperature by the sensor is affected, and the temperature of the air cabin is unstable after the aircraft takes off and suddenly heated due to the fact that the temperature sensing of the cabin temperature sensor is not obvious. To the aforesaid problem, if need thoroughly clean cabin sensor pipeline, need dismantle the luggage rack at first, then tear open the sensor pipeline, reuse dust catcher clean, such mode pollutes the cabin easily, and is difficult to clean up, and whole process time cost is too high simultaneously, and the airline maintenance can't accomplish. It is therefore necessary to study a special cleaning device for the internal piping of the aforementioned cabin temperature sensor. Disclosure of utility model One of the purposes of the present utility model is to provide a cleaning device for a pipeline of an aircraft cabin temperature sensor, so as to solve the technical problems of complicated operation, long time consumption, easy pollution to the cabin and the like in the prior art, which are caused by detaching the pipeline of the cabin temperature sensor to clean dust and impurities. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides an aircraft cabin temperature sensor pipeline cleaning device which comprises a supporting seat, wherein the supporting seat is used for being installed on an air outlet corresponding to a temperature sensor, a filter bag is sleeved on the supporting seat, the device further comprises a combined pipeline, the combined pipeline is used for being respectively communicated with an air inlet of the temperature sensor and an external air source, the external air source is used for conveying air through the combined pipeline from the air inlet of the temperature sensor, and the air is discharged from the air outlet after passing through a pipeline of the temperature sensor. Preferably, the support seat is arranged on a luggage rack of an aircraft cabin, and the filter bag covers an air outlet of the temperature sensor. The combined pipeline comprises a first pipe body and a second pipe body, wherein the first pipe body is used for being communicated with an air inlet of the temperature sensor, the first pipe body is also communicated with the second pipe body, and the second pipe body is communicated with the external air source. The further technical scheme is that the first pipe body and the second pipe body, the air inlet of the first pipe body and the temperature sensor, and the connecting part between the second pipe body and the external air source are fixedly connected through the clamping bolt. Compared with the prior art, the utility model has the beneficial effects that the air inlet of the cabin temperature sensor is connected with an external air source through the combined pipeline, the filter bag is arranged at the air outlet of the temperature sensor through the supporting seat, and then the external pressurized air can enter from the air inlet of the temperature sensor, so that dust and impurities deposited in the pipeline are blown out from the air outlet to the filter bag for collection, further, the impurities in the pipeline can be cleaned without disassembling the luggage rack and the temperature sensor pipeline, the pipeline blockage is avoided, the temperature acquisition in the cabin is influenced, the cleaning efficiency of the temperature sensor is obviously improved, and the time cost for maintaining the air route is reduced.
