Description

Technical Field

[0001] This utility model relates to the field of self-priming device technology, specifically a self-priming device for an aircraft de-icing vehicle. Background Technology

[0002] A de-icing truck is a specialized vehicle used for removing ice and snow, primarily for de-icing aircraft and roads. Aircraft de-icing trucks use pressurized, heated de-icing fluid to de-ic the aircraft's icy areas or the entire aircraft. They can also perform cleaning and maintenance. After the ice is removed from the aircraft surface, it melts into water, requiring wastewater recycling. This wastewater can be drawn into a treatment tank using a self-priming device on the de-icing truck. However, traditional self-priming devices are often difficult to adjust in position. When wastewater needs to be absorbed from different locations, the de-icing truck's position must be adjusted, making it inconvenient to use. To address this issue, a self-priming device for aircraft de-icing trucks is proposed.

[0003] The suction nozzle structure of a self-priming negative pressure dust removal cleaning vehicle disclosed in authorization announcement number CN207244531U includes a suction nozzle body, which has a large cavity and a small cavity that are interconnected. A row-type roller brush is provided in the large cavity; a spiral roller brush is provided in the small cavity; an intake port is provided on the bottom surface of the suction nozzle body corresponding to the large cavity; the lower part of the outer edge of the row-type roller brush protrudes from the intake port; an outlet port is provided on the suction nozzle body corresponding to one end of the spiral roller brush in the small cavity; a driving device is provided on the suction nozzle body, which is connected to the roller shafts of the row-type roller brush and the spiral roller brush respectively; guide wheels are provided on the front and rear sides of the suction nozzle body respectively.

[0004] Although it not only expands the cleaning area and can effectively clean the corners of the road, it can also clean up the dust, floating objects and other garbage on the road and square; it can directly sweep the particles attached to the ground or in the crevices into the small cavity and convey them to one end for discharge through the spiral roller brush, so that the cleaned ground is clean and thorough.

[0005] However, it has not solved the problem that existing self-priming devices are not conducive to convenient bidirectional movement and adjustment of the suction position during use, nor to simultaneous reciprocating oscillation suction of sewage at multiple positions, which affects the efficiency and effectiveness of sewage suction and treatment. Utility Model Content

[0006] The purpose of this invention is to provide a self-priming device for an aircraft de-icing vehicle, in order to solve the problems mentioned in the background art, such as the inconvenience of bidirectional movement and adjustment of the suction position of the self-priming device, the disadvantage of multi-position synchronous reciprocating oscillating suction of sewage, and the impact on the efficiency and effectiveness of sewage suction and treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-priming device for an aircraft de-icing vehicle, comprising an integrated frame and a bidirectional lead screw. The bidirectional lead screw is movably installed inside the integrated frame.

[0025] Please see Figure 1-5 This utility model provides an embodiment of a self-priming device for an aircraft de-icing vehicle, comprising an integrated frame 1 and a bidirectional lead screw 15. The bidirectional lead screw 15 is movably installed inside the integrated frame 1. A drive motor 14 is provided on the side wall of the integrated frame 1, which serves as a power drive. The output end of the drive motor 14 is connected to the bidirectional lead screw 15. Two sets of threaded sleeves 2 are fitted on the surface of the bidirectional lead screw 15, and the threaded sleeves 2 are threadedly connected to the bidirectional lead screw 15. A connecting plate 3 is installed on the side wall of each threaded sleeve 2. A connecting pipe 5 is installed at the bottom end of each connecting plate 3. A left corrugated hose 16 is installed at one end of each connecting pipe 5, and a right corrugated hose 13 is installed at the other end of each connecting pipe 5. An axial flow fan 8 is provided inside each connecting pipe 5. A power box 4 is installed at the top end of each connecting pipe 5. A power mechanism 7 is provided inside each power box 4, and the power output end of the power mechanism 7 is connected to the axial flow fan 8. A drive frame 6 is installed at the bottom end of each connecting pipe 5.

[0026] Install the integrated frame 1 on the de-icing truck, and connect the left corrugated hose 16 to the collection box of the de-icing truck. When it is necessary to absorb and treat the sewage generated on the ground due to de-icing, turn on the power mechanism 7 inside the power box 4. The power mechanism 7 drives the axial flow fan 8 to rotate, and the axial flow fan 8 provides suction to the inside of the right corrugated hose 13. Place the right corrugated hose 13 at the sewage position, so that the sewage is absorbed into the collection box of the de-icing truck through the right corrugated hose 13, connecting pipe 5 and left corrugated hose 16. At the same time, the drive motor 14 can be turned on. The machine 14 drives the bidirectional lead screw 15 to rotate. With the bidirectional lead screw 15 and the threaded sleeve 2 connected by threads, the bidirectional lead screw 15 drives the two sets of threaded sleeves 2 to move in the same direction or opposite directions. The threaded sleeves 2 drive the two sets of connecting pipes 5 and right corrugated hoses 13 to move away from each other or closer to each other, thereby adjusting the absorption position of the two sets of right corrugated hoses 13. This facilitates the suction of sewage from different positions, thereby improving the efficiency of sewage suction. It realizes convenient bidirectional movement adjustment of the suction position, which facilitates simultaneous suction of sewage at multiple positions and improves the efficiency of sewage suction treatment.

[0027] Servo motors 17 are installed on the outer wall of the drive frame 6. The servo motors 17 serve as power drives, and worm gears 18 are installed at the output ends of the servo motors 17. Worm wheels 19 are movably installed inside the drive frame 6 on one side of the worm gear 18, and the worm wheels 19 mesh with the worm gear 18. A long linkage arm 20 is movably installed at the eccentric position at the top of the worm wheel 19, and a short linkage arm 21 is movably installed at the end of the long linkage arm 20 away from the worm wheel 19.

[0028] A swing shaft 22 is fixedly installed at the end of the short linkage arm 21 away from the long linkage arm 20. The swing shaft 22 extends to the outside of the drive frame 6 and is movably connected to the drive frame 6. A swing arm 9 is installed at the bottom of the swing shaft 22. A telescopic arm 11 is provided inside the swing arm 9, and the telescopic arm 11 is slidably connected to the swing arm 9.

[0029] The top of each swing arm 9 is equipped with a positioning bolt 10, and the positioning bolt 10 extends through the swing arm 9 to the surface of the telescopic arm 11. The end of the telescopic arm 11 away from the swing arm 9 is provided with an adjusting arm 12, and the adjusting arm 12 is connected to the right corrugated hose 13.

[0030] When the two sets of right corrugated hoses 13 are at their farthest distance, loosen the positioning bolt 10, pull the adjusting arm 12, and the adjusting arm 12 drives the telescopic arm 11 to slide inside the swing arm 9. The adjusting arm 12 drives the right corrugated hose 13 to move to the optimal suction position. Then, tighten the positioning bolt 10, turn on the servo motor 17, and the servo motor 17 drives the worm gear 18 to rotate. Under the mutual meshing of the worm gear 18 and the worm wheel 19, the worm gear 18 drives the worm wheel 19 to rotate, and the worm wheel 19 drives the long linkage arm 20 to swing back and forth. The long linkage arm 20 drives the short linkage arm 21 to swing back and forth. The short linkage arm 21 drives the swing arm 9, the telescopic arm 11, the adjusting arm 12, and the right corrugated hose 13 to swing back and forth through the swing shaft 22. At the same time, in conjunction with the de-icing truck, the de-icing truck drives the right corrugated hose 13 to perform a traveling reciprocating swing to suck up sewage, which increases the suction range and improves the sewage suction and treatment effect.

[0031] Working Principle: The integrated frame 1 is installed on the de-icing truck. The left corrugated hose 16 is connected to the collection box of the de-icing truck. When it is necessary to absorb and treat the sewage generated by de-icing on the ground, the power mechanism 7 inside the power box 4 is opened. The power mechanism 7 drives the axial flow fan 8 to rotate, and the axial flow fan 8 provides suction to the right corrugated hose 13. The right corrugated hose 13 is placed at the sewage position, so that the sewage is absorbed into the collection box of the de-icing truck through the right corrugated hose 13, connecting pipe 5, and left corrugated hose 16. The drive motor 14 drives the bidirectional screw 15 to rotate, and the bidirectional screw 15 drives the two sets of threaded sleeves 2 to move in the same direction or opposite directions. The threaded sleeves 2 drive the two sets of connecting pipes 5 and right corrugated hose 13 to move away from or towards each other, thereby adjusting the absorption position of the two sets of right corrugated hoses 13 to facilitate the suction of sewage from different positions, thereby improving the efficiency of sewage treatment. To improve water suction efficiency, when the two sets of right corrugated hoses 13 are furthest apart, loosen the positioning bolt 10, pull the adjusting arm 12, and the adjusting arm 12 drives the telescopic arm 11 to slide inside the swing arm 9. The adjusting arm 12 then drives the right corrugated hose 13 to move to the optimal suction position. After that, tighten the positioning bolt 10, and the servo motor 17 drives the worm gear 18 to rotate. The worm gear 18 drives the worm wheel 19 to rotate, and the worm wheel 19 drives the long linkage arm 20 to swing back and forth. The long linkage arm 20 drives the short linkage arm 21 to swing back and forth. The short linkage arm 21 drives the swing arm 9, telescopic arm 11, adjusting arm 12, and right corrugated hose 13 to swing back and forth through the swing shaft 22. At the same time, in conjunction with the de-icing truck, the de-icing truck drives the right corrugated hose 13 to perform a traveling reciprocating swing to suction sewage. The above is the complete usage of the self-priming device of the aircraft de-icing truck.
