DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-6 The present invention is described in further detail.

[0024] The embodiment of the present invention discloses a ground well joint tray. Figure 1 The ground well connector pallet includes a pallet body 1, which is installed to the side of the aircraft refueling truck. The pallet body 1 is used to place the ground well connector 2. The pallet body 1 is movably provided with a folding cylinder 3 that can be stretched or contracted. Specifically, the folding cylinder 3 adopts a folding corrugated cover, and the folding cylinder 3 is retracted in the vertical direction. The ground well connector 2 is located in the folding cylinder 3, and the interlocking system on the pallet body 1 for self-locking the ground well connector 2 is also located in the folding cylinder 3, thereby not affecting the self-locking of the ground well connector 2.

[0025] Reference Figure 1A bracket 4 is fixed on the pallet body 1. The bracket 4 includes a first support plate 41 and a second support plate 42. The first support plate 41 and the second support plate 42 are both fixed on the pallet body 1. The ground well joint 2 and the folding cylinder 3 are both located between the first support plate 41 and the second support plate 42. Specifically, the arrangement direction of the first support plate 41 and the second support plate 42 is parallel to the length direction of the aircraft refueling truck. The first support plate 41 is located on the side of the second support plate 42 close to the forward direction of the aircraft refueling truck. A cover plate 5 is hinged on the upper end of the first support plate 41. The hinge axis of the cover plate 5 is arranged in the horizontal direction. Specifically, the hinge axis of the cover plate 5 is perpendicular to the arrangement direction of the first support plate 41 and the second support plate 42. A rotating rod 7 is fixedly penetrated on the cover plate 5. The rotating rod 7 rotates on the first support plate 41. The cover plate 5 is rotatably connected to the first support plate 41 through the rotating rod 7. The side of the cover plate 5 away from the first support plate 41 is used to cooperate with the second support plate 42. The cover plate 5 is located above the folding cylinder 3 and is used to cover the folding cylinder 3 to protect the ground-well joint 2. A transmission member 6 is provided on the cover plate 5, and the transmission member 6 is used to drive the folding cylinder 3 to extend and unfold upward when the cover plate 5 rotates toward the direction close to the ground-well joint 2 on the tray body 1.

[0026] After the ground well connector 2 is placed on the tray body 1, the cover plate 5 is rotated in the direction close to the ground well connector 2. During the rotation of the cover plate 5, the folding cylinder 3 is driven to extend and unfold upward through the transmission member 6, so that the folding cylinder 3 gradually rises to cover the ground well connector 2 until the cover plate 5 is rotated to cooperate with the second support plate 42, and the upper end of the folding cylinder 3 is covered by the cover plate 5, thereby completely covering the ground well connector 2, so that during the operation of the aircraft refueling truck, rain, snow and ground mud and sand are not easy to splash into the gap of the ground well connector 2, which helps to ensure the connection and sealing effect of the ground well connector 2 when the aircraft is refueling.

[0027] When the ground well connector 2 needs to be taken out for use, the cover plate 5 is rotated in the direction away from the ground well connector 2. During the rotation of the cover plate 5, the folding cylinder 3 is retracted downward under the action of gravity, gradually exposing the ground well connector 2, and the cover plate 5 naturally falls down under gravity. Then the operator can take the ground well connector 2 out of the tray body 1.

[0028] Reference Figure 1 and Figure 2In order to facilitate the cover plate 5 to rotate in the direction close to the ground well joint 2 on the tray body 1, the folding cylinder 3 is driven to extend and unfold upward, the transmission member 6 includes a drum 61 and a pull rope 62, the drum 61 is coaxially fixedly sleeved on the rotating rod 7, and two drums 61 are provided, the two drums 61 are located at both ends of the rotating rod 7, the drum 61 is located above the folding cylinder 3, the pull rope 62 corresponds to the drum 61 one by one, one end of the pull rope 62 is wound around the corresponding drum 61, and the other end is fixed to the upper end of the folding cylinder 3. When the cover plate 5 rotates in the direction close to the ground well joint 2 on the tray body 1, the drum 61 rotates to reel in the corresponding pull rope 62. Specifically, the diameter of the drum 61 can be set according to the height of the ground well joint 2, so that when the cover plate 5 rotates from the side of the first support plate 41 away from the second support plate 42 to cooperate with the second support plate 42, the drum 61 can pull the folding cylinder 3 up to the upper end of the ground well joint 2 by reeling in the pull rope 62.

[0029] When the cover plate 5 rotates toward the direction approaching the ground well joint 2 on the pallet body 1, the reel 61 rotates to reel in the corresponding pull rope 62. At this time, the pull rope 62 gradually pulls the upper end of the folding cylinder 3, thereby driving the folding cylinder 3 to gradually rise until the cover plate 5 cooperates with the second support plate 42, and the folding cylinder 3 covers the ground well joint 2, thereby helping to protect the ground well joint 2 through the cooperation between the folding cylinder 3 and the cover plate 5; when the cover plate 5 rotates toward the direction away from the ground well joint 2 on the pallet body 1, the reel 61 rotates to unwind the pull rope 62. At this time, the pulling force of the pull rope 62 on the folding cylinder 3 is reduced, and the folding cylinder 3 is retracted downward under the action of its own gravity, exposing the ground well joint 2, thereby facilitating the removal of the ground well joint 2 from the pallet body 1.

[0030] Reference Figure 1 and Figure 2 A receiving groove 26 is formed on the second support plate 42 , and the receiving groove 26 is used to receive the cover plate 5 . When the cover plate 5 rotates to a horizontal state directly above the folding tube 3 , the cover plate 5 overlaps the receiving groove 26 .

[0031] Reference Figure 3 and Figure 4 The cover plate 5 is provided with a locking member for fixing the cover plate 5 and the second support plate 42 relatively. In order to facilitate the relative fixing of the cover plate 5 and the second support plate 42, the locking member includes a locking tongue 8, which is slidably penetrated on the side of the cover plate 5 away from the rotating rod 7, and the sliding direction of the locking tongue 8 is parallel to the plane where the cover plate 5 is located. Furthermore, the sliding direction of the locking tongue 8 is perpendicular to the rotation axis of the rotating rod 7. An operating rod 25 is fixed on the locking tongue 8, and the operating rod 25 slides through the side of the cover plate 5 away from the ground well joint 2. A bar hole (not marked in the figure) for the operating rod 25 to slide is opened on the cover plate 5. By toggling the operating rod 25, the locking tongue 8 can be adjusted to slide, and the receiving groove 26 (refer to Figure 1) A locking groove 9 for plugging with the locking tongue 8 is opened on the side wall. When the cover plate 5 is rotated to a horizontal state directly above the ground well joint 2, the cover plate 5 overlaps the receiving groove 26, and the locking tongue 8 is aligned with the locking groove 9.

[0032] When it is necessary to relatively fix the cover plate 5 and the second support plate 42, the operating rod 25 is slid toward the direction close to the locking groove 9, so that the operating rod 25 drives the locking tongue 8 to move into the locking groove 9, thereby limiting the rotation of the cover plate 5, so that the cover plate 5 is not prone to bounce when the aircraft refueling truck is bumpy; when it is necessary to open the cover plate 5, the operating rod 25 is slid toward the direction away from the locking groove 9, so that the locking tongue 8 is disengaged from the locking groove 9, and the cover plate 5 can be rotated toward the direction away from the ground well connector 2, so that the ground well connector 2 is convenient to be taken out.

[0033] Reference Figure 3 and Figure 4 In order to reduce the number of operating steps for the operator, a first magnet 15 is fixed to the bottom wall of the lock slot 9, and a second magnet 16 is fixed to the end of the lock tongue 8 away from the cover plate 5, and the first magnet 15 is used to be adsorbed and matched with the second magnet 16. When the cover plate 5 rotates to the receiving groove 26 and the lock tongue 8 is aligned with the lock slot 9, under the adsorption effect of the first magnet 15 and the second magnet 16, the first magnet 15 drives the lock tongue 8 to move into the lock slot 9 until the first magnet 15 and the second magnet 16 are adsorbed and matched, without the need for manual sliding of the operating rod 25, and the lock tongue 8 is not prone to abnormal sliding during the operation of the aircraft refueling truck.

[0034] Reference Figure 3 and Figure 4 A groove 27 is provided on one side of the cover plate 5 close to the ground well joint 2, and a sliding block 10 is slidably arranged in the groove 27. The sliding direction of the sliding block 10 is parallel to the plane where the cover plate 5 is located. In order to prevent the sliding block 10 from being separated from the groove 27, the sliding block 10 is a T-shaped, dovetail-shaped, etc., which is not limited here. An adjustment component is provided on the cover plate 5, and the adjustment component is used to adjust the sliding block 10 to slide toward or away from the interface on the ground well joint 2. A mounting plate 11 is provided on the sliding block 10, and the length direction of the mounting plate 11 is used to be perpendicular to the plane where the cover plate 5 is located. Specifically, the sliding direction of the sliding block 10 is perpendicular to the arrangement direction of the first support plate 41 and the second support plate 42. When the ground well connector 2 is placed on the tray body 1, the interface of the ground well connector 2 is perpendicular to the arrangement direction of the first support plate 41 and the second support plate 42. On the one hand, it is convenient to remove the ground well connector 2, and on the other hand, it makes it difficult for the mounting plate 11 to interfere with the first support plate 41 and the second support plate 42 during the rotation of the cover plate 5.

[0035] Reference Figure 3 and Figure 4The ground-well joint 2 is placed on the tray body 1. When the cover plate 5 is locked with the second support plate 42, the ground-well joint 2 is located on the side of the mounting plate 11 close to the center of the cover plate 5. A connecting tube 12 is rotatably provided on the side of the mounting plate 11 close to the ground-well joint 2. The rotation axis of the connecting tube 12 is parallel to the sliding direction of the sliding block 10.

[0036] Reference Figure 4 and Figure 5 The connecting tube 12 is a structure with one end sealed and the other end open. The opening of the connecting tube 12 faces the side away from the mounting plate 11. The connecting tube 12 is used to align with the interface on the ground-well joint 2. The connecting tube 12 is provided with a rotating part for driving the connecting tube 12 to rotate. The connecting tube 12 is provided with a cleaning part for cleaning the interface on the ground-well joint 2.

[0037] When the cover plate 5 rotates toward the direction close to the ground-well joint 2, the sliding block 10 on the cover plate 5 is located on the side away from the ground-well joint 2 under the action of the adjusting component, so that when the cover plate 5 is rotated to cooperate with the receiving groove 26, the mounting plate 11 and the connecting tube 12 on the mounting plate 11 will not interfere with the ground-well joint 2, thereby avoiding potential damage to the ground-well joint 2; when the cover plate 5 is overlapped on the receiving groove 26, the sliding block 10 is adjusted by the adjusting component to drive the mounting plate 11 and the connecting tube 12 to approach the ground-well joint 2, so that the cleaning piece on the connecting tube 12 is abutted and aligned with the interface of the ground-well joint 2, and then the connecting tube 12 is driven to rotate by the rotating piece, which helps the cleaning piece to rotate and clean the interface of the ground-well joint 2, thereby improving the comprehensiveness of the cleaning, and the cleaning piece directly acts on the interface, thereby effectively solving the cleaning problem of the interface on the ground-well joint 2.

[0038] Reference Figure 4 In order to facilitate the adjustment of the sliding block 10 to slide in the direction close to or away from the ground well joint 2, the adjustment component includes a pulling spring 13 and a connecting piece. The pulling spring 13 is located inside the cover plate 5. The extension direction of the pulling spring 13 is parallel to the sliding direction of the sliding block 10. The pulling spring 13 is located on the side of the sliding block 10 away from the center of the cover plate 5. One end of the pulling spring 13 is fixed on the inner wall of the cover plate 5, and the other end is fixed on the side of the sliding block 10 away from the center of the cover plate 5. The pulling spring 13 is used to pull the sliding block 10 to move in the direction away from the ground well joint 2. In the embodiment of the present invention, two pulling springs 13 are provided. The connecting piece is provided on the locking tongue 8, and the connecting piece is used to drive the sliding block 10 to move in the direction close to the ground well joint 2 when the locking tongue 8 slides in the direction away from the cover plate 5.

[0039] Reference Figure 3 and Figure 4In order to facilitate the sliding of the sliding block 10, a guide pulley 28 is fixed at a position near the center of the cover plate 5, and the connecting rope 14 between the sliding block 10 and the locking tongue 8 is slidably overlapped on the guide pulley 28. When the locking tongue 8 slides in the direction away from the cover plate 5, the connecting rope 14 pulls the sliding block 10 to move in the direction close to the ground well joint 2. The adsorption force between the first magnet 15 and the second magnet 16 is greater than the sum of the elastic forces of the two pulling springs 13. When the pulling spring 13 is in a natural state, the connecting rope 14 is in a tensioned state.

[0040] When the first magnet 15 and the second magnet 16 are disengaged, the sliding block 10 is located at the initial position under the action of the pulling spring 13, that is, the position away from the ground-well joint 2, so that during the rotation of the cover plate 5 toward the ground-well joint 2, the mounting plate 11 and the connecting tube 12 on the mounting plate 11 will not interfere with the ground-well joint 2, thereby avoiding potential damage to the ground-well joint 2. When the locking tongue 8 is aligned with the locking groove 9, the first magnet 15 attracts the second magnet 16 to drive the locking tongue 8 to move toward the locking groove 9, and the locking tongue 8 pulls the sliding block 10 to move toward the ground-well joint 2 through the connecting rope 14, so as to facilitate the cleaning piece on the mounting plate 11 to abut against the interface on the ground-well joint 2.

[0041] Reference Figure 4 and Figure 5 In order to facilitate driving the connecting tube 12 to rotate, the rotating part includes an air inlet pipe 17, a first air transfer pipe 18, a second air transfer pipe 19 and a fan blade 20. The air inlet pipe 17 is arranged on the cover plate 5. The air inlet pipe 17 has an air inlet end and an air outlet end. Specifically, the air inlet pipe 17 includes a fixed pipe 171 and a rotating pipe 172. The fixed pipe 171 is fixedly penetrated on a side of the cover plate 5 away from the sliding block 10. The fixed pipe 171 is located at the center of the cover plate 5. The rotating pipe 172 is connected to the fixed pipe 171. The rotating pipe 172 is L-shaped. The end of the rotating pipe 172 away from the fixed pipe 171 is the air inlet end, and the end of the fixed pipe 171 away from the rotating pipe 172 is the air outlet end. When the cover plate 5 is overlapped with the receiving groove 26, the air inlet end is arranged in the horizontal direction and the air inlet end is aligned with the forward direction of the aircraft refueling truck, so that during the forward movement of the aircraft refueling truck, the rotating pipe 172 can effectively capture the airflow generated during driving.

[0042] Reference Figure 4 and Figure 5The first air transmission pipe 18 is fixedly embedded in the cover plate 5, the length direction of the first air transmission pipe 18 is parallel to the sliding direction of the sliding block 10, the first air transmission pipe 18 is located between the fixed pipe 171 and the sliding block 10, the air outlet end of the fixed pipe 171 is connected to the first air transmission pipe 18, the second air transmission pipe 19 is slidably sleeved on one end of the first air transmission pipe 18 close to the sliding block 10, the first air transmission pipe 18 is connected to the second air transmission pipe 19, the sliding direction of the second air transmission pipe 19 is parallel to the sliding direction of the sliding block 10, and the second air transmission pipe 19 is away from the first air transmission pipe 1 One end of 8 is penetrated on the sliding block 10, and a cavity 21 is provided on the sliding block 10 and the mounting plate 11, the second air transmission pipe 19 is connected with the cavity 21 in the sliding block 10 through a branch pipe 35, the cavity 21 in the sliding block 10 is connected with the cavity 21 on the mounting plate 11 through the branch pipe 35, and an air inlet cavity 29 is provided on the side of the connecting tube 12 close to the mounting plate 11, and the air inlet cavity 29 is connected with the cavity 21 on the mounting plate 11, and the fan blade 20 is coaxially fixed in the air inlet cavity 29 of the connecting tube 12, and the fan blade 20 is aligned with the cavity 21 on the mounting plate 11.

[0043] The airflow generated during the operation of the aircraft refueling truck enters the rotating tube 172 and the fixed tube 171 through the air inlet end on the rotating tube 172, and then enters the cavity 21 in the sliding block 10 through the first air transmission tube 18 and the second air transmission tube 19. Then the airflow enters the cavity 21 in the mounting plate 11 through the branch pipe 35. The airflow continuously entering the mounting plate 11 drives the fan blades 20 to rotate, and the fan blades 20 drive the connecting tube 12 to rotate, so that the connecting tube 12 drives the cleaning piece to rotate to clean the interface of the ground well joint 2.

[0044] Reference Figure 4 and Figure 5 In order to facilitate cleaning of the interface of the ground-well joint 2, the cleaning piece includes bristles 22 arranged on the connecting tube 12, and the bristles 22 are long soft hairs. An air outlet hole 23 is opened on the side of the connecting tube 12 close to the ground-well joint 2. The air outlet hole 23 is connected with the air inlet cavity 29 on the connecting tube 12, so that the air outlet hole 23 is connected with the cavity 21 inside the mounting plate 11. Furthermore, the air outlet hole 23 is a small hole, and the number of the air outlet holes 23 can be set as needed.

[0045] During the rotation of the connecting tube 12, the connecting tube 12 drives the bristles 22 to brush the interface of the ground-well joint 2, and the bristles 22 can directly contact and remove the dirt at the interface of the ground-well joint 2; at the same time, the airflow blown out of the air outlet 23 can immediately take away the loosened dust and impurities, preventing these dirt from being deposited at the interface again. In addition, the airflow can also penetrate into the small gaps that the bristles 22 cannot directly contact, further improving the cleaning effect.

[0046] Reference Figure 4The rotating tube 172 is rotatably connected to the fixed tube 171, and the rotation axis of the rotating tube 172 is perpendicular to the plane where the cover plate 5 is located. The rotating tube 172 is provided with a wind vane 24, and the wind vane 24 is located on the side of the rotating tube 172 away from the air inlet end. The wind vane 24 can drive the rotating tube 172 to rotate under the action of wind force, so that the air inlet end of the rotating tube 172 is always aligned with the direction of the wind, thereby ensuring the stability of the overall structure of the air inlet tube 17 and realizing the flexible adjustment of the air inlet direction in windy weather.

[0047] Reference Figure 1 and Figure 4 A pressing elastic ball 30 is slidably provided on one side of the cover plate 5 close to the sliding block 10. The sliding direction of the pressing elastic ball 30 is perpendicular to the rotation axis of the rotating rod 7. The pressing elastic ball 30 and the cover plate 5 are slidably connected through the cooperation of the guide block and the guide groove, so that the pressing elastic ball 30 will not be separated from the cover plate 5. The pressing elastic ball 30 is used to abut against the curved neck of the grounding well joint 2. A reset member for resetting the pressing elastic ball 30 is provided on the cover plate 5.

[0048] Reference Figure 1 and Figure 4 In order to facilitate the reset of the pressing elastic ball 30, the reset member includes a reset spring 31. The extending direction of the reset spring 31 is parallel to the sliding direction of the pressing elastic ball 30. One end of the reset spring 31 is fixed on the cover plate 5, and the other end is fixed on the pressing elastic ball 30. When the reset spring 31 is in a natural state, the pressing elastic ball 30 is located at a position on the cover plate 5 aligned with the bent neck of the well joint 2; when the reset spring 31 is in a natural state, the guide block abuts against the side of the guide groove close to the rotating rod 7, so that the pressing elastic ball 30 will no longer move toward the direction close to the rotating rod 7.

[0049] When the cover plate 5 is rotated toward the direction close to the ground well connector 2 to cooperate with the receiving groove 26, the return spring 31 is in a natural state, so that the pressing elastic ball 30 is pressed tightly against the bent neck of the ground well connector 2, thereby preventing the ground well connector 2 from bouncing up due to bumps during the operation of the aircraft refueling truck.

[0050] Reference Figure 4 and Figure 5 The mounting plate 11 is hinged on the sliding block 10, the hinge axis of the mounting plate 11 is perpendicular to the sliding direction of the sliding block 10, the hinge axis of the mounting plate 11 is parallel to the plane where the cover plate 5 is located, the branch pipe 35 is a retractable bellows, and a hinge rod 32 is passed through the mounting plate 11, and the hinge rod 32 rotates on the sliding block 10. A driving member is provided on the hinge rod 32, and the driving member is used to drive the mounting plate 11 to rotate and reset.

[0051] Reference Figure 4 and Figure 5In order to facilitate the rotation and reset of the mounting plate 11, the driving member includes a torsion spring 33 mounted on the hinge rod 32, one end of the torsion spring 33 is fixed on the sliding block 10, and the other end is fixed on the mounting plate 11. When the torsion spring 33 is in a natural state, the length direction of the mounting plate 11 is perpendicular to the plane where the cover plate 5 is located.

[0052] Reference Figure 4 and Figure 6 A transmission rope 34 is fixed between the pressing elastic ball 30 and the mounting plate 11, and a guide ring is fixed on a side of the cover plate 5 close to the ground well joint 2. The guide ring is located between the pressing elastic ball 30 and the sliding block 10. The transmission rope 34 between the pressing elastic ball 30 and the mounting plate 11 slides through the guide ring. When the reset spring 31 and the torsion spring 33 are both in the natural state, the transmission rope 34 is in a tensioned state.

[0053] When the cover plate 5 rotates toward the direction close to the ground well connector 2 to cooperate with the receiving groove 26, under the action of the return spring 31 and the torsion spring 33, the elastic ball 30 is pressed to align with the curved neck of the ground well connector 2, and the mounting plate 11 is perpendicular to the plane where the cover plate 5 is located, so that the cleaning piece on the connecting tube 12 can clean the interface position of the ground well connector 2.

[0054] When the cover plate 5 rotates in a direction away from the ground well joint 2, so that the angle between the side of the cover plate 5 close to the air inlet pipe 17 and the side of the first support plate 41 away from the second support plate 42 is less than 90 degrees, the cover plate 5 rotates downward, so that the pressing elastic ball 30 moves in a direction away from the rotating rod 7 under the action of its own gravity, stretching the reset spring 31, and the pressing elastic ball 30 pulls the mounting plate 11 to rotate in a direction close to the cover plate 5 through the transmission rope 34, so that the connecting tube 12 on the mounting plate 11 is buckled on the cover plate 5, thereby helping to protect the bristles 22 on the connecting tube 12 and the air outlet 23, keeping the bristles 22 clean and the air outlet 23 not easily blocked. When the cover plate 5 rotates to a vertical state toward the direction close to the ground well joint 2, the elastic ball 30 is pressed to gradually move toward the direction close to the rotating rod 7 under the action of its own gravity, so that the reset spring 31 returns to a natural state, and the tension of the elastic ball 30 on the transmission rope 34 is reduced. The mounting plate 11 rotates toward the direction away from the cover plate 5 under the action of the torsion spring 33 to reset, so that the mounting plate 11 returns to the plane perpendicular to the cover plate 5.

[0055] The implementation principle of the embodiment of the present invention is as follows: after the ground well connector 2 is placed on the tray body 1, the interface on the ground well connector 2 is oriented perpendicular to the arrangement direction of the first support plate 41 and the second support plate 42 and aligned with the side where the mounting plate 11 is located, and then the cover plate 5 is rotated in the direction close to the ground well connector 2. During the rotation of the cover plate 5, the reel 61 is driven to rotate by the rotating rod 7, so that the reel 61 reels up the corresponding pull rope 62, and the pull rope 62 gradually pulls the folding cylinder 3 to extend and unfold upward. At the same time, under the action of the reset spring 31 and the torsion spring 33, the elastic ball 30 is pressed to gradually move in the direction of the rotating rod 7, and the mounting plate 11 is rotated in the direction away from the cover plate 5. Since the first magnet 15 and the second magnet 16 are in a disengaged state at this time, the sliding block 10 is located away from the ground well connector 2 under the action of the pulling spring 13.

[0056] When the cover plate 5 is rotated to a vertical state above the first support plate 41, the elastic ball 30 and the mounting plate 11 are fully reset, and then the cover plate 5 continues to rotate in the direction close to the ground well connector 2 until the cover plate 5 rotates and overlaps the receiving groove 26. At this time, the folding cylinder 3 rises to cover the ground well connector 2, and the cover plate 5 covers the upper end of the folding cylinder 3, and the locking tongue 8 is aligned with the locking groove 9. The elastic ball 30 is pressed tightly on the curved neck of the ground well connector 2, and then the first magnet 15 in the locking groove 9 absorbs the second magnet 16 on the locking tongue 8, so that the first magnet 15 and the second magnet 16 are absorbed and matched, and the locking tongue 8 is inserted into the locking groove 9 to complete the locking of the cover plate 5. The ground well connector 2 can be completely covered by the folding cylinder 3 and the cover plate 5, so that during the operation of the aircraft refueling truck, rain, snow and ground mud and sand are not easy to splash into the gap of the ground well connector 2, which helps to ensure the connection and sealing effect of the ground well connector 2 when the aircraft is refueled.

[0057] In the process of the lock tongue 8 moving toward the direction close to the lock groove 9, the lock tongue 8 pulls the sliding block 10 to move toward the direction close to the ground well joint 2 through the connecting rope 14, so that the bristles 22 on the connecting tube 12 abut against the interface of the ground well joint 2; when the aircraft refueling truck is running, the generated airflow first causes the weather vane 24 to be located on the leeward side of the rotating tube 172, so that the airflow enters the rotating tube 172 and the fixed tube 171 through the air inlet end on the rotating tube 172, and then enters the cavity 21 in the sliding block 10 through the first air transmission tube 18 and the second air transmission tube 19, and then the airflow enters the cavity 21 in the mounting plate 11 through the branch pipe 35. The airflow continuously entering the mounting plate 11 drives the fan blade 20 to rotate, and the fan blade 20 drives the connecting tube 12 to rotate, so that the connecting tube 12 drives the bristles 22 to rotate to clean the interface of the ground well joint 2. At the same time, the airflow blown out of the air outlet 23 can immediately take away the dust and impurities loosened by the brush, so as to realize the double cleaning of the interface of the ground well joint 2.

[0058] When it is necessary to take out the ground well connector 2 for use, the operating rod 25 is slid in the direction away from the second support plate 42, and the operating rod 25 drives the locking tongue 8 away from the locking groove 9, so that the tension of the locking tongue 8 on the connecting rope 14 is reduced, and the sliding block 10 drives the mounting plate 11 and the connecting tube 12 away from the ground well connector 2 under the tension of the pulling spring 13, so that the bristles 22 on the connecting tube 12 are separated from the ground well connector 2, and then the cover plate 5 is rotated in the direction away from the ground well connector 2. During the rotation of the cover plate 5, the rotating rod 7 drives the winding drum 61 to rotate and unwind the pull rope 62. At this time, the tension of the pull rope 62 on the folding tube 3 is reduced, and the folding tube 3 is retracted downward under the action of its own gravity, gradually exposing the ground well connector 2, thereby facilitating the operator to take the ground well connector 2 out of the tray body 1.

[0059] When the cover plate 5 rotates under the action of gravity to an angle less than 90 degrees with the side of the first support plate 41 away from the second support plate 42, the elastic ball 30 is pressed to move in the direction away from the rotating rod 7 under the action of its own gravity. The elastic ball 30 pulls the mounting plate 11 to rotate toward the direction close to the cover plate 5 through the transmission rope 34, so that the connecting tube 12 on the mounting plate 11 is buckled on the cover plate 5, thereby helping to protect the bristles 22 and the air outlet 23 on the connecting tube 12.

[0060] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
