Description

Technical Field

[0001] This utility model relates to an exhaust inspection device, specifically an exhaust inspection device for an aircraft cockpit canopy system refueling system, belonging to the field of aviation repair. Background Technology

[0002] In engineering applications, dissolved air in liquids is generally considered not to affect the bulk modulus of hydraulic fluid or its quality. However, if dissolved gas precipitates from the fluid due to localized low pressure, forming bubbles, or if air is introduced during fluid filling, or if poor sealing of components allows air to be drawn in during operation, these will form free gas in the fluid, causing serious impacts and damage to the hydraulic system and components. Furthermore, air entering the hydraulic system reduces the system's transmission stiffness, leading to decreased transmission efficiency and unstable pressure.

[0003] Currently, the method involves visually inspecting the oil flowing from the drain port during system refueling and venting to check for air bubbles. If no visible air bubbles are found, it is assumed that there is no free gas in the system. However, this method is heavily influenced by subjective judgment and cannot effectively verify whether the gas inside the system has been effectively vented. Utility Model Content

[0006] A refueling and exhaust inspection device for an aircraft cockpit canopy system includes a housing. Multiple connectors for pipe installation are installed on the lower side wall of the housing. The two ends of the connectors are located inside and outside the housing, respectively. A transparent observation tube is connected to the end of the connector located inside the housing. The observation tube is designed to be open at both ends.

[0007] Optionally, the observation tube is made of transparent glass, and one end of the observation tube is fitted onto the outside of one end of the connector and fixed by adhesive silicone.

[0008] Optionally, a plug is threaded to the end of the connector located outside the housing, and the plug is shaped like a hexagonal nut.

[0009] Optionally, the end of the plug furthest from the connector is connected to a connecting pin, and an anti-detachment rope is attached to the outside of the connecting pin. The other end of the anti-detachment rope is connected to the outer wall of the connector.

[0011] Optionally, a pad is connected to the bottom of the handle, and both ends of the pad are connected to the side wall or lid of the box by screws.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-3 As shown, an aircraft cockpit canopy system refueling and exhaust inspection device includes a housing 4. Multiple connectors 7 for pipe installation are installed on the lower side wall of the housing 4. The two ends of the connectors 7 are located inside and outside the housing 4, respectively. A transparent observation tube 6 is connected to the end of the connector 7 located inside the housing 4, and the observation tube 6 is open at both ends. The housing 4 is made of stainless steel, and the connectors 7 are welded and fixed to the housing 4.

[0022] Specifically, the observation tube 6 is made of transparent glass, specifically high-borosilicate glass with high transparency, facilitating subsequent observation of the oil flowing inside. One end of the observation tube 6 is fitted onto the outside of one end of the connector 7 and secured with silicone adhesive. The silicone adhesive bonding method is simpler and more efficient, reducing the impact that the observation tube 6 may suffer during use.

[0023] Specifically, a plug 8 is threadedly connected to the end of the connector 7 located outside the housing 4. The plug 8 is hexagonal in shape. The plug 8 seals the end of the connector 7. When the connector 7 is not in use, the plug 8 is threaded onto the connector 7, preventing external impurities from entering the interior of the connector 7 and ensuring its normal operation. When the connector 7 needs to be connected to the drain pipe of the aircraft's drain port, the plug 8 can be unscrewed to remove it.

[0024] Specifically, the end of the cap 8 furthest from the connector 7 is connected to a connecting pin, and an anti-detachment rope 9 is attached to the outside of the connecting pin. The other end of the anti-detachment rope 9 is connected to the outer wall of the connector 7. After the cap 8 is unscrewed from the connector 7, it is not easy to lose due to the restriction of the anti-detachment rope 9.

[0025] Specifically, a matching lid 5 is installed on the top of the container 4, and handles 1 are connected to the top of the lid 5 and the upper sides of both sides of the container 4. The handles 1 facilitate lifting the lid 5 and allow workers to move the container 4 using the handles 1, making it easier to apply force to the container 4. The lid 5 is fitted onto the top of the container 4.

[0026] Specifically, a pad 3 is connected to the bottom of the handle 1, and both ends of the pad 3 are connected to the side wall of the box 4 or the box cover 5 by screws 2.

[0027] When checking whether the internal gas of the canopy system has been effectively vented, first remove the cap 8, pull the cover 5 upwards and remove it from the top of the housing 4. Connect the aircraft drain port to the threaded end of the connector 7 via the process hose. The aircraft fuel flows through the process hose and connector 7 into the observation tube 6, and finally into the storage compartment inside the housing 4. The aircraft fuel is a light red and transparent color, and bubbles in the observation tube 6 can be observed through the fuel from the top of the housing 4. When there is gas in the aircraft fuel, numerous small bubbles will aggregate into larger bubbles as they pass through the observation tube 6, making bubble observation easier. The bursting of bubbles after they rise to the surface can also help determine whether there are bubbles in the aircraft fuel, and thus the extent of gas venting within the system. The presence of bubbles indicates that the internal gas has not been fully vented. After the aircraft fuel has been drained to the point where the fuel level in the housing 4 exceeds the top of the observation tube 6, the presence of gas in the fuel can be determined by observing whether bubbles emerge from the outlet of the observation tube 6. The generation of bubbles indicates that the internal gas has not been fully vented.

[0028] After inspection, disconnect the process hose from connector 7. The aircraft oil inside the housing 4 will drain out through connector 7 and can be stored in the pre-designated container. If the residual oil inside the housing 4 cannot drain through connector 7, hold the handles 1 on both sides to lift the housing 4 and pour out the residual oil from the top of the housing 4. Finally, after cleaning the inside of the housing 4, close the lid 5 to prevent dust.
