Description

Technical Field

[0001] This utility model relates to a special pipeline cleaning tool, and more specifically, this utility model mainly relates to a cleaning device for aircraft cabin temperature sensor pipelines. Background Technology

[0002] Aircraft cabin temperature sensors are typically located behind overhead bins. During use, dust and impurities easily accumulate in the internal tubing of these sensors, causing blockages and affecting their ability to accurately capture cabin temperatures. This results in unstable cabin temperatures after takeoff, fluctuating between hot and cold. To address this issue, thoroughly cleaning the sensor tubing requires disassembling the overhead bins, removing the tubing, and then cleaning with a vacuum cleaner. This method easily contaminates the cabin, is difficult to clean thoroughly, and is time-consuming, making it impractical for line maintenance. Therefore, it is necessary to research a dedicated cleaning device for the internal tubing of these cabin temperature sensors. Utility Model Content

[0003] One of the objectives of this invention is to address the aforementioned shortcomings by providing an aircraft cabin temperature sensor pipeline cleaning device. This device aims to solve the technical problems in the prior art, which require disassembling the cabin temperature sensor pipeline to clean dust and impurities. Such procedures are not only complex and time-consuming, but also prone to contaminating the cabin.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The present invention provides a cleaning device for the pipeline of an aircraft cabin temperature sensor, including a support base for mounting on the air outlet corresponding to the temperature sensor, and a filter bag fitted on the support base; the device also includes a combined pipeline for connecting to the air inlet of the temperature sensor and an external air source respectively, the external air source for supplying gas through the combined pipeline from the air inlet of the temperature sensor, and the gas being discharged from the air outlet after passing through the pipeline of the temperature sensor.

[0006] As a preferred embodiment, a further technical solution is that the support is installed on the overhead luggage rack in the aircraft cabin, and the filter bag covers the air outlet of the temperature sensor.

[0007] A further technical solution is: the combined pipeline includes a first pipe body and a second pipe body, the first pipe body is used to connect to the air inlet of the temperature sensor, the first pipe body is also connected to the second pipe body, and the second pipe body is connected to the external air source.

[0008] A further technical solution is that the first tube and the second tube, the connection between the first tube and the air inlet of the temperature sensor, and the connection between the second tube and the external air source are all fixedly connected by bolts.

[0009] Compared with the prior art, one of the beneficial effects of this utility model is that by connecting the air inlet of the cabin temperature sensor to an external air source through a combined pipeline, and then installing a filter bag at the air outlet of the temperature sensor through a support, external pressurized gas can enter through the air inlet of the temperature sensor, blowing the dust and impurities deposited in the pipeline out of the air outlet and collecting them in the filter bag. Thus, the impurities inside the sensor can be cleaned without disassembling the overhead luggage rack and the temperature sensor pipeline, avoiding pipeline blockage that affects its temperature acquisition in the cabin, and significantly improving the efficiency of temperature sensor cleaning, reducing the time cost spent on line maintenance.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] refer to Figure 1 As shown, one embodiment of this utility model is a cleaning device for the temperature sensor pipeline in an aircraft cabin. It includes a collection unit and an air supply unit. The collection unit includes a support 1, which is used to install on the air outlet corresponding to the temperature sensor. A filter bag 2 is fitted on the support 1. Correspondingly, the air supply unit includes a combined pipe 3, which is used to connect to the air inlet of the temperature sensor and an external air source, respectively. This allows the external air source to deliver gas through the combined pipe 3 from the air inlet of the temperature sensor. The gas passes through the pipeline of the temperature sensor and is discharged from the air outlet. This causes dust, impurities, and other blockages in the temperature sensor pipeline to be blown out by the airflow and enter the filter bag 2 through the air outlet, achieving the technical purpose of cleaning the temperature sensor without disassembling it.

[0015] In this embodiment, the air inlet of the cabin temperature sensor is connected to an external air source through a combined pipe 3, and a filter bag 2 is installed at the air outlet of the temperature sensor through a support. Pressurized gas from outside can enter through the air inlet of the temperature sensor and blow the dust and impurities deposited in the pipeline out through the air outlet to the filter bag 2 for collection. This allows for the cleaning of impurities inside the sensor without disassembling the overhead luggage rack and the temperature sensor pipeline, avoiding pipeline blockage that could affect temperature acquisition in the cabin. It also significantly improves the efficiency of temperature sensor cleaning and reduces the time cost of line maintenance.

[0016] Furthermore, for ease of use, the support base 1 can be detachably installed on the overhead luggage rack in the aircraft cabin via hooks 5, and the filter bag 2 can cover the air outlet of the temperature sensor to prevent blockages in the temperature sensor pipeline from being blown out and scattered in the cabin. On the other hand, for easy connection to an external air source, the aforementioned combined pipeline 3 is preferably configured as a first pipe body 31 and a second pipe body 32. The first pipe body 31 is a flexible hose with a reducer, which facilitates connection to the air inlet of the temperature sensor pipeline, which is also a flexible hose connector. The second pipe body 32 is a rigid pipe for supplying air to the external air source, which is connected to the aforementioned flexible hose with a reducer. To ensure the stability of the connection between the pipe bodies, a clamp 4 can be used to fix the connection between the first pipe body 31 and the second pipe body 32, the connection between the first pipe body 31 and the air inlet of the temperature sensor, and the connection between the second pipe body 32 and the external air source.

[0017] refer to Figure 1 and Figure 2 As shown, in a preferred embodiment of this utility model, during line maintenance, the flexible hose of the combined pipeline is directly connected to the air inlet of the aircraft cabin temperature sensor, while the rigid pipe is connected to an external air source such as a nitrogen cylinder filling pipe, a portable air pump filling pipe, or a manual air pump pipe. Then, a support base 1 is installed on the aircraft overhead luggage rack, and a filter bag 2 is installed on the support base 1, ensuring that the filter bag 2 completely covers the aforementioned air inlet and its surrounding area. After installation, gas is injected into the air inlet of the temperature sensor through the combined pipeline 3 using an external air source. The pipeline is cleared using a pressure not exceeding 55 PSI, and blockages and dust are blown into the collection filter bag by the pressure, effectively resolving pipeline blockage without contaminating the cabin. The special tools are then removed, and the aircraft is restored to its initial state. After the pipeline is cleared, the pressure inside is normal, the cabin temperature sensor can detect temperature normally, and the cabin temperature is adjustable and stable.

[0018] This invention enables airlines to reduce costs and increase efficiency. The specialized tools can unclog pipes without disassembling them and without causing cabin contamination. They are compatible with common air supply connectors, ensuring quick and efficient resolution of such malfunctions. Furthermore, the devices facilitate management and mitigate risks. Labeled and managed in the tool room, these specialized tools are specifically designed for handling blocked cabin temperature sensor pipes, preventing loss and ensuring that tools are not mistakenly or randomly used. This plays a crucial role in standardizing operations.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.
