[0002] When the temperature is too low in winter, ice will accumulate on the surface of the aircraft wings. If the aircraft is flying in clouds containing cold water droplets, water vapor condenses on the aircraft wings, which will destroy the aerodynamic structure and affect flight safety. Therefore, in winter, de-icing fluid will be sprayed on the fuselage before the aircraft takes off, which means that an aircraft de-icing vehicle is needed to cooperate with the staff to carry out de-icing.

[0003] The authorization announcement number is CN215475820U, and the name is a fine-tuning device for the operating cabin of an aircraft de-icing vehicle.

The operator works in the external environment for a long time and is easily eroded by cold wind, which affects the de-icing efficiency. Secondly, the sleeve 21 is not equipped with a positioning mechanism to fix the de-icing gun. When spraying at multiple angles, it will be subjected to a large impact force, and it requires more physical strength to operate the de-icing gun. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 6 The present invention provides an aircraft de-icing vehicle with an enclosed de-icing compartment, comprising a vehicle body 1 and a drive arm 2 connected to the vehicle body 1. The end of the drive arm 2 is connected to a compartment 3, and the front end of the compartment 3 is connected to an observation window 5 and a support frame 6. The compartment 3 adopts an enclosed design to reduce the impact of the external environment on the operator, who can observe the external environment through the observation window 5. A door 4 is hinged on the side of the compartment 3. Opening the door 4 allows entry into the compartment 3, facilitating spraying operations. A fixed frame 9 is provided in the support frame 6, and the support frame 6 and the fixed frame 9 are connected by a movable mechanism. The fixed frame 9 is connected to a limiting mechanism for limiting the de-icing gun 7. The limiting mechanism includes multiple springs 16, multiple limiting blocks 18, multiple pressing blocks 17, a pressing ring 10, and multiple connecting grooves 11. The connecting groove 11 matches the connecting head 20 connected to the outside of the de-icing gun 7. The spring 16 is used to drive the limiting block 18 to move toward the direction close to the de-icing gun 7, the pressing ring 10 is used to drive the pressing block 17 to move, and the pressing block 17 is used to drive the limiting block 18 to rise and fall.

[0022] The movable mechanism includes a ball seat 12, a sphere 13, and a support column 14. Ball seat 12 is connected to the bottom of fixed frame 9, and sphere 13 is slidably connected to ball seat 12. Both ends of support column 14 are connected to support frame 6 and sphere 13. Support column 14 provides support for fixed frame 9 and de-icing gun 7, allowing the de-icing gun 7 to move at multiple angles, simultaneously driving the movement of fixed frame 9. Ball 13 slides within ball seat 12, thereby expanding the spraying range and improving de-icing efficiency.

[0023] A rubber pad 8 is connected between the support frame 6 and the fixed frame 9. The rubber pad 8 is elastic, which not only facilitates the movement of the fixed frame 9 and the de-icing gun 7, but also serves the purpose of isolation, preventing external de-icing liquid from entering the cabin 3 through the gap between the support frame 6 and the fixed frame 9.

[0024] The limiting mechanism also includes multiple pressing posts 15, multiple inclined slots 19, and multiple inclined surfaces 21. The two ends of the pressing posts 15 are connected to the pressing ring 10 and the pressing block 17. The pressing block 17 is slidably connected to the inclined slots 19. The inclined slots 19 are provided on the side of the limiting block 18, and the inclined surfaces 21 are provided at the end of the limiting block 18. There can be three pressing posts 15, and correspondingly, there are three connecting slots 11 and three limiting blocks 18. When installing the de-icing gun 7, align the connecting head 20 with the connecting groove 11, and apply a thrust to the de-icing gun 7 to make the connecting head 20 slide in the connecting groove 11. The connecting head 20 slides relative to the inclined surface 21, which can drive the limit block 18 to move upward, and the spring 16 is gradually compressed until the connecting head 20 rests on the inner side of the connecting groove 11. The compressed spring 16 drives the limit block 18 to move back, so that the limit block 18 is connected to the back side of the connecting head 20. Combined with the use of the connecting groove 11, the de-icing gun 7 can be limited and fixed, thereby improving the stability of the connection between the de-icing gun 7 and the fixing frame 9, and is safe and reliable to use.

[0025] The inclined surface 21 is a smooth surface, which can reduce the friction between the inclined surface 21 and the connector 20 .

[0026] The pressing post 15 is slidably connected to the fixing frame 9 to improve the stability of the movement of the pressing post 15 .

[0027] A guide groove is provided in the fixing frame 9 , and the limit block 18 is slidably connected to the guide groove, so that the limit block 18 moves stably.

[0028] The spring 16 is located in the guide groove, and both ends of the spring 16 are connected to the fixing frame 9 and the limit block 18 .

[0029] Working principle: Open the cabin door 4, and the personnel enter the cabin body 3. The operator swings the de-icing gun 7 to spray, which is convenient for cleaning the ice and snow on the surface of the aircraft. The cabin body 3 is a closed design, which reduces the impact of the external environment on the operator, and then the operator can understand the external spraying situation through the observation window 5. When installing the de-icing gun 7, the connector 20 is docked with the connecting groove 11, and a thrust is applied to the de-icing gun 7, so that the connector 20 and the inclined surface 21 slide relative to each other, which can lift the limit block 18 and the spring 16 is gradually compressed until the connector 20 is connected to the innermost part of the connecting groove 11. The compressed spring 16 drives the limit block 18 to move back, so that the limit block 18 is connected to the back of the connector 20, thereby limiting and fixing the de-icing gun 7, and achieving high installation efficiency. When the spraying is completed and the de-icing gun 7 needs to be disassembled, a thrust is applied to the pressing ring 10, and the three pressing columns 15 move synchronously, thereby driving the pressing block 17 to slide in the inclined groove 19, and the limit block 18 can be driven to move upward until the limit block 18 is separated from the connecting head 20, thereby loosening the connecting head 20, thereby facilitating the removal of the de-icing gun 7 from the fixing frame 9, which is highly efficient.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
