[0002] Aircraft are susceptible to corrosion due to prolonged exposure to harsh environments. Regularly applying anti-corrosion coatings to the wheel wells is a crucial measure for maintaining the structural integrity of aircraft. Traditional manual spraying methods suffer from low efficiency, uneven application, and high health risks to operators. While some auxiliary tools exist in current technologies, they still have limitations such as complex operation, insufficient spraying precision, and room for improvement in environmental performance. Utility Model Content

[0011] The beneficial effects of this utility model are:

[0012] In this invention, through the arrangement of a preservative storage tank, a spray nozzle, and a preservative delivery mechanism, a delivery pump draws the preservative from the storage tank into a delivery pipe, which then enters the spray nozzle. During spraying, the operator can hold the flexible hose 14 to spray the aircraft wheel wells and adjust the spraying position. The position of the adjustment device can be adjusted to regulate the spraying area, resulting in a more uniform spraying of the aircraft wheel wells. The heat pipe heats the air, and the fan blows hot air towards the spraying position, allowing for post-spray drying of the sprayed area and accelerating the drying of the preservative.

[0013] In this invention, the height adjustment mechanism, baffle, and purification mechanism are designed to allow the height adjustment screw to rotate when the motor rotates. This rotation of the screw then moves the nut on the screw, allowing the device to be adjusted to a suitable spraying height for easier spraying. The baffle blocks the spread of the preservative from the operator's side, slowing down the spread of the preservative. The exhaust fan draws the spread preservative into the purification filter through the exhaust pipe for purification. The purified air is then discharged through the exhaust pipe, protecting the environment and the health of the operators. Attached Figure Description

[0022] The preservative to be sprayed is added to the preservative storage tank 3 through the addition pipe 13. The amount of preservative added can be observed through the liquid level bar on the preservative storage tank 3. The device is moved and its direction of movement is adjusted, and the device is pushed into the bottom of the aircraft wheel well. The height adjustment mechanism 10 can be used to adjust the device to a suitable spraying height for convenient spraying. The preservative delivery mechanism 6 can draw the preservative from the preservative storage tank 3 to the nozzle 5, and spray it upwards onto the aircraft wheel well through the nozzle 5. During spraying, the operator can... Holding the flexible hose 14, spray the aircraft wheel wells and adjust the spraying position. The position of the adjustment device can be adjusted to adjust the spraying area, making the operation relatively convenient and the spraying of the aircraft wheel wells relatively uniform. The heat drying mechanism 8 can blow hot air to the spraying position and heat dry the sprayed position after spraying to accelerate the drying of the preservative. During spraying, the baffle 4 can block the spread of the preservative on the operator's side and slow down the spread of the preservative. The purification mechanism 9 can purify the air to protect the environment and the health of the operators.

[0023] In this embodiment of the utility model, specifically, the preservative delivery mechanism 6 includes a delivery pump 61 fixedly installed on the top of the preservative storage tank 3. A pumping pipe 62 is fixedly installed at the inlet end of the delivery pump 61, and the pumping pipe 62 is located inside the preservative storage tank 3. A delivery pipe 63 is fixedly installed at the outlet end of the delivery pump 61, and the other end of the delivery pipe 63 is connected to the nozzle 5 through a holding hose 14.

[0024] To achieve the application of the preservative, the delivery pump 61 draws the preservative from the preservative storage tank 3 into the delivery pipe 63 through the delivery pipe 62, and then through the delivery pipe 63 and the holding hose 14 into the nozzle 5. The preservative is then sprayed upwards onto the aircraft wheel wells through the nozzle 5. During spraying, the operator can hold the holding hose 14 to spray the aircraft wheel wells and adjust the spraying position, making the operation convenient and the spraying of the aircraft wheel wells relatively uniform.

[0025] In this embodiment of the utility model, specifically, the heating mechanism 8 includes a heat pipe 81 fixedly installed at the lower end of the heating box 7 and a support plate 82 horizontally installed at the upper end of the heating box 7. A fan 83 is fixedly installed on the support plate 82, and the direction of the fan 83 is vertically upward.

[0026] To heat the sprayed preservative and accelerate its drying process, heat pipe 81 heats the air, and fan 83 blows hot air towards the spraying position, thus heating the sprayed area and accelerating the drying of the preservative.

[0027] In this embodiment of the utility model, specifically, the purification mechanism 9 includes a purification filter element 91 fixedly installed at the bottom of the lifting plate 2. The air inlet end of the purification filter element 91 is connected to the air outlet of the exhaust fan 93. The exhaust pipe 92 is fixed on the baffle 4 in the vertical direction. The air inlet of the exhaust fan 93 is connected to the lower end of the exhaust pipe 92. An exhaust pipe 94 is fixedly installed at the air outlet end of the purification filter element 91.

[0028] To reduce the absorption of airborne preservatives by operators, a vertically installed baffle 4 is used during spraying to block the preservative from spreading to the operator's side, slowing down its diffusion. An exhaust fan 93 draws the diffused preservative through an exhaust pipe 92 into a purification filter 91 for purification. The purified air is then discharged through an exhaust pipe 94, protecting the environment and the health of the operators.

[0029] In this embodiment of the utility model, specifically, the height adjustment mechanism 10 includes a nut 101 fixedly installed on the lifting plate 2, a height adjustment screw 102 rotatably installed on the support plate 1 in the vertical direction, an adjustment motor 103 fixedly installed at the bottom of the support plate 1, the height adjustment screw 102 and the output end of the adjustment motor 103 being coaxially connected, and the nut 101 and the height adjustment screw 102 being threadedly connected.

[0030] To adjust the spraying height of the device, the rotation of the adjusting motor 103 will drive the height adjusting screw 102 to rotate. The rotation of the height adjusting screw 102 will drive the nut 101 to move on the height adjusting screw 102, thereby adjusting the device to a suitable spraying height for convenient spraying.

[0031] In this embodiment of the utility model, a guide rod 104 is fixedly installed on the support plate 1 along the vertical direction, and the lifting plate 2 is slidably installed on the guide rod 104.

[0032] In order to guide the movement of the lifting plate 2, the guide rod 104 can guide the movement of the lifting plate 2, so that the lifting plate 2 can only move up and down along the guide rod 104.

[0033] In this embodiment of the utility model, a push handle 11 is fixedly installed on the support plate 1, a caster wheel 12 is provided at the bottom of the support plate 1, and an addition tube 13 is connected to the upper end of the preservative storage tank 3.

[0034] To facilitate adjusting the position of the device, grasp the push handle 11 and push the device; the casters 12 roll and rotate on the ground to move the device and adjust the direction of movement.

[0035] Working principle: During use, the preservative to be sprayed is added to the preservative storage tank 3 through the addition tube 13. The amount of preservative added can be observed through the level bar on the preservative storage tank 3. Then, hold the push handle 11 and push the device; the casters 12 roll and rotate on the ground, allowing the device to move and its direction of movement to be adjusted. Push the device into the bottom of the aircraft wheel well. Then, start the adjustment motor 103. The rotation of the adjustment motor 103 will drive the height adjustment screw 102 to rotate. The guide rod 104 guides the movement of the lifting plate 2, ensuring that the lifting plate 2 can only move up and down along the guide rod 104, thus adjusting the height. Rotating the height adjustment screw 102 will cause the nut 101 to move on the height adjustment screw 102, which can adjust the device to a suitable spraying height to facilitate spraying. When spraying, the delivery pump 61 is started. The delivery pump 61 will draw the preservative in the preservative storage tank 3 into the delivery pipe 63 through the delivery pipe 62, and then into the nozzle 5 through the delivery pipe 63. The nozzle 5 will then spray the preservative upwards onto the aircraft wheel well. When spraying, the operator can hold the holding hose 14 to spray the aircraft wheel well and adjust the spraying position. The position of the device can be adjusted and the spraying area can be adjusted to ensure that the spraying of the aircraft wheel well is relatively uniform. Heat pipe 81 heats the air, and fan 83 blows hot air toward the spraying position, which can heat the sprayed position after spraying to accelerate the drying of the preservative. During spraying, baffle 4 can block the preservative from spreading to the operator's side and slow down the spread of the preservative. Exhaust fan 93 will draw the spread preservative into the purification filter 91 through exhaust pipe 92 for purification. The purified air will be discharged through exhaust pipe 94 to protect the environment and the health of the operator.
