[0029] See attached Figure 1 The embodiment of the present application provides an aircraft deicing and anti-icing liquid sampling device, including a liquid collecting tank 1 and a liquid hopper 2. The liquid collecting tank 1 is divided into a waste liquid bin 101 and a sampling bin. The waste liquid bin 101 is used to collect the deicing and anti-icing liquid sprayed 15 seconds before the anti-icing vehicle, and the sampling bin is used to collect the deicing and anti-icing liquid sprayed 15 seconds after the anti-icing vehicle. The outer wall of the liquid collecting tank 1 is respectively provided with a drain pipe connected to the waste liquid bin 101 and a sampling pipe connected to the sampling bin. In particular, the waste liquid bin 101 is in a "convex" structure and is located in the sampling bin, so that the bin wall of the waste liquid bin 101 is close to the side wall of the liquid collecting tank 1, which is convenient for setting the drain pipe. At the same time, a waste liquid inlet 105 is provided on the top side of the waste liquid bin 101, and a sample liquid inlet 106 is provided on the top side of the sampling bin. The waste liquid inlet 105 and the sample liquid inlet 106 are located on the same side but on concentric circles of different diameters.

[0030] like Figure 1 and Figure 2 As shown, a liquid hopper 2 is rotatably provided on the top of the liquid collecting box 1. In order to realize the autonomous rotation of the liquid hopper 2, a motor 7 is provided on the top of the liquid collecting box 1. The output end of the motor 7 is fixedly connected to the bottom center of the liquid hopper 2. In order to protect the motor 7, a protective cover is provided outside the motor 7.

[0031] In the above, the liquid hopper 2 is centrally provided with a partition 203, which divides the liquid hopper 2 into a first hopper body 201 and a second hopper body 202. The first hopper body 201 and the second hopper body 202 are not blocked on the side of the partition 203, so that the anti-icing vehicle can spray the deicing and anti-icing liquid into the liquid hopper 2. Of course, the first hopper body 201 and the second hopper body 202 are integrally formed with a panel higher than the bottom of the hopper on the side of the partition 203 to prevent the deicing and anti-icing liquid from overflowing. At the same time, the bottom of the first hopper body 201 is provided with a waste liquid outlet 204, and the bottom of the second hopper body 202 is provided with a sample liquid outlet 205. The waste liquid outlet 204 is provided with a first liquid inlet pipe 3, which introduces the waste liquid from the waste liquid inlet 105 into the waste liquid bin 101. The sample liquid outlet 205 is provided with a second liquid inlet pipe 4, which introduces the sample liquid from the sample liquid inlet 106 into the sample liquid bin 102.

[0032] It can be imagined that during the rotation of the liquid hopper 2, the first liquid inlet pipe 3 and the second liquid inlet pipe 4 will rotate synchronously with the liquid hopper 2. Since the first liquid inlet pipe 3 and the second liquid inlet pipe 4 are introduced into the waste liquid inlet 105 and the sample liquid inlet 106, in order to avoid the first liquid inlet pipe 3 and the second liquid inlet pipe 4 being restricted by the waste liquid inlet 105 and the sample liquid inlet 106 and affecting the rotation of the hopper, see Figure 2 and Figure 3As shown, the first liquid inlet pipe 3 and the second liquid inlet pipe 4 are elastic telescopic pipes, and the first liquid inlet pipe 3 and the second liquid inlet pipe 4 can be extended and shortened during the rotation of the liquid hopper 2. Specifically, the elastic telescopic pipe includes an outer sleeve 340, an inner bellows 341 and a spring 343. Among them, the outer sleeve 340 is vertically arranged at the waste liquid outlet 204 and the sample liquid outlet 205 respectively, and a first annular boss 344 is arranged on the outer wall of the outer sleeve 340 near the bottom of the tube; the inner bellows 341 is vertically arranged at the waste liquid outlet 204 and the sample liquid outlet 205 respectively and is located in the outer sleeve 340, coaxial with the outer sleeve 340 and a gap is left between each other to facilitate the extension and contraction of the inner bellows 341 in the outer sleeve 340, and a hard conical joint 342 extending out of the outer sleeve 340 is arranged at the end of the inner bellows 341, and the hard conical joint 342 is correspondingly connected to the waste liquid inlet 105 and the sample liquid inlet 106, and a second annular boss 345 is arranged on the outer wall of the hard conical joint 342; the spring 343 is sleeved on the outer sleeve 340, and the two ends of the spring 343 are fixedly connected to the first annular boss 344 and the second annular boss 345 respectively. It is conceivable that, since the first liquid inlet tube 3 and the second liquid inlet tube 4 are located on opposite sides, and the first liquid inlet tube 3 is located in the waste liquid inlet in the initial state, when the liquid hopper 2 rotates under the drive of the motor 7, the conical joint is subjected to force to compress the spring 343, and is brought out of the waste liquid inlet 105 under the compression of the spring 343, while the second liquid inlet tube 4 rotates with the liquid hopper 2 and reaches the sample liquid inlet 106, and the spring 343 bounces the hard joint into the sample liquid inlet 106, thereby completing the liquid inlet switching of the first liquid inlet tube 3 and the second liquid inlet tube 4. It is conceivable that the provision of the hard conical joint 342 facilitates the first liquid inlet tube 3 and the liquid inlet tube to enter and exit the waste liquid inlet 105 and the sample liquid inlet 106.

[0033] In a preferred embodiment, in order to guide the steering of the first liquid inlet pipe 3 and the second liquid inlet pipe 4, see Figure 1 As shown, the top of the liquid collecting box 1 is respectively provided with a first semicircular guide groove 5 and a second semicircular guide groove 6 for sliding of the first liquid inlet pipe 3 and the second liquid inlet pipe 4. When the motor 7 rotates, the first liquid inlet pipe 3 and the second liquid inlet pipe 4 move along the first semicircular guide groove 5 and the second semicircular guide groove 6.

[0034] Based on the above content, the present application provides an aircraft deicing and anti-icing fluid sampling device, and the method of use is:

[0035] First, the first bucket 201 is facing the side of the de-icing vehicle. At this time, the first liquid inlet pipe 3 is connected to the waste liquid inlet 105, and the second liquid inlet pipe 4 is located on the opposite side of the first liquid inlet pipe 3 and is not connected to the sample liquid inlet 106. The first bucket 201 and the second bucket 202 are separated by the partition 203. The de-icing vehicle sprays deicing and anti-icing liquid into the first bucket 201 for 15 seconds. The sprayed deicing and anti-icing liquid is a waste liquid that cannot be used for detection. It enters the waste liquid bin 101 from the first liquid inlet pipe 3 through the waste liquid inlet 105.

[0036] After 15 seconds of spraying, the control motor 7 rotates to drive the liquid hopper 2 to rotate 180 degrees. During the rotation of the liquid hopper 2, the first liquid inlet pipe 3 is compressed as the liquid hopper 2 rotates, and the conical joint where it is located is subjected to force to compress the spring 343, and is brought out of the waste liquid inlet 105 under the compression of the spring 343, while the second liquid inlet pipe 4 rotates with the liquid hopper 2 to reach the sample liquid inlet 106. At this time, the spring 343 where the second liquid inlet pipe 4 is located is reset from the compressed state to drive the conical joint where it is located to enter the sample liquid inlet 106, thereby introducing the deicing and anti-icing liquid sprayed after 15 seconds into the sample liquid tank 102, and stopping after the preset spraying time. At this time, the waste liquid in the waste liquid tank 101 can be discharged through the drain pipe, and samples can be taken from the sample liquid tank 102 for inspection through the sample tube.

[0037] Of course, in the above process, in order to reduce the splashing of the deicing and anti-icing fluid caused by the impact of the partition 203 during the spraying process, as shown in FIG. Figure 1 and Figure 2 As shown, sponges 206 may be optionally provided on both sides of the partition 203 to alleviate the impact of spraying deicing and anti-icing liquid on the partition 203 and reduce liquid splashing.

[0038] In summary, an aircraft de-icing and anti-icing fluid sampling device provided in an embodiment of the present application is designed to centrally design two containers for collecting waste liquid and collecting sample liquid in a liquid collecting tank 1, and to respectively introduce the waste liquid and sample liquid into the corresponding waste liquid bin 101 and sample liquid bin 102 by providing a rotatable liquid hopper 2 on the top of the liquid collecting tank 1, so that one liquid collecting tank 1 can complete the collection of waste liquid and sample liquid, which greatly facilitates the use of detection personnel.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
