[0012] The advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model of a spray-type aircraft cleaning vehicle consists of a bottom vehicle body, a middle lifting mechanism, and a top spraying device. The bottom vehicle body provides support for the entire vehicle. The middle lifting mechanism can lift the top spraying device to a position above the aircraft surface. The top spraying device adopts an extendable large-area spraying structure, and the entire spraying device can rotate around its lower center, enabling large-area spray cleaning of the aircraft surface. Combined with the directional rotation of the middle lifting mechanism around the lower rotating support, it can achieve rapid spray cleaning of the entire aircraft surface, greatly improving cleaning efficiency.

[0014] 2. The central lifting mechanism of this utility model adopts a combination structure of a bottom support, a main arm, and a secondary arm. The bottom support connects to the bottom vehicle body and adjusts the orientation of the central lifting mechanism. The main arm connects to the bottom support and adjusts and controls the lifting height. The main arm connects to the secondary arm and adjusts and controls the relative distance between the spray-type aircraft cleaning vehicle and the aircraft, as well as the direction of the spray water. Specifically, when cleaning the top of the aircraft, the secondary arm can be adjusted to a near-horizontal position, at which point the spray water direction is nearly vertical, which can better cover the top of the aircraft. When cleaning the sides of the aircraft, the secondary arm can be tilted upwards, so that the spray water direction is set at an angle. With the spray-type aircraft cleaning vehicle moving around the aircraft, the sides of the aircraft can be tilted in all directions, achieving a better cleaning effect while saving water.

[0015] 3. This utility model of spray-type aircraft cleaning vehicle does not require people to stand at a high altitude to work. They only need to stand on the ground to make grooves in the cleaning vehicle, which ensures the safety of the operation and reduces the labor intensity of cleaning. Attached Figure Description

[0021] The structure of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0022] Please see the following: A spray-type aircraft cleaning vehicle. Figures 1-5 The invention features a bottom body section 1, a middle lifting mechanism 2, and a top spraying device 3.

[0023] The bottom vehicle body can be a self-driving vehicle structure with a power source, or a vehicle structure without a power source that requires traction from other equipment. In this utility model, to simplify the vehicle structure, the bottom vehicle body adopts a vehicle structure without a power source. Specifically, the bottom vehicle body includes a frame 1.1, two wheels 1.2, and four ground support cylinders 1.3. A traction bracket 1.5 is provided at the center of the front end of the vehicle body. The four ground support cylinders are vertically fixed to the four corners of the frame with the cylinder rods facing in the same direction. Foot pads 1.4 for contacting the bottom surface are fixed to the ends of the cylinder rods. The two wheels are mounted on the left and right sides of the middle of the lower end of the vehicle body via axles. When the spray-type aircraft cleaning vehicle does not need to be moved, the cylinder rods of the four ground support cylinders extend downwards and contact the ground through the foot pads. At this time, the two traveling wheels are off the ground. When the spray-type aircraft cleaning vehicle needs to be moved, the cylinder rods of the four ground support cylinders retract, the two wheels contact the ground, and the traction bracket is connected to the traction equipment. The movement of the traction equipment drives the spray-type aircraft cleaning vehicle to move.

[0024] The central lifting mechanism is used to raise the top spraying device to a position above the surface of the aircraft to be cleaned. In this invention, the central lifting mechanism includes a bottom support 2.2, a main boom 2.5, and a secondary boom 2.7. The bottom support is connected to the upper support beam of the bottom vehicle body via a lower slewing support 2.1 and is driven by a lower hydraulic rotary motor (not shown in the drawings), enabling ±180° rotation. One end of the main boom is hinged to the upper end of the bottom support via a lower pin. A lower drive cylinder 2.3 is connected between the lower side of the bottom support near the lower end and the outer side of the main boom, driving the main boom to rotate around the center of the lower pin, thus raising and lowering the main boom. The other end of the main boom is hinged to one end of the secondary boom via an upper pin. An upper drive cylinder 2.6 is connected between the inner side of the main boom near its other end and the lower side of the secondary boom near that end, driving the secondary boom to rotate around the center of the upper pin, thus raising and lowering the secondary boom. Both the main boom and the auxiliary boom adopt a multi-section telescopic boom structure, referencing the telescopic boom structure of existing construction machinery. Multiple sheaves 2.4 are installed on both sides of the first section of the main boom and both sides of the first section of the auxiliary boom. Cable tray clamps (U-shaped frames, not shown in the attached drawings) are fixed to both sides of the tail end of each section of the main boom and each auxiliary boom section, used to guide and transport oil, electricity, and water pipelines upwards.

[0025] The top spraying device is connected to the end of the auxiliary arm via an upper slewing support 3.11 and is driven by an upper hydraulic rotary motor (not shown in the attached diagram), enabling it to rotate ±180°. The top spraying device employs a multi-section retractable spray template assembly structure. Preferably, a four-section structure is used, including a middle left spray template 3.2, a middle right spray template 3.6, a left left spray membrane plate 3.1, a right right spray membrane plate 3.10, a template mounting frame, and two retraction drive cylinders 3.5. All four spray template sections have an internally enclosed water chamber and a bottom densely packed spray heads. A water inlet is provided on the side of each spray template section, connected to a delivery pipeline. The template mounting frame consists of an upper horizontal frame 3.3, a left side frame 3.2, and a right side frame 3.9. The upper horizontal frame is positioned above the end of the final section of the auxiliary arm, and its lower middle section is connected to the end of the final section of the auxiliary arm via an upper slewing support. The middle left and middle right spray templates are fixed to the lower end of the upper horizontal frame, with a spraying length of 1.2m. One end of the left side frame and one end of the right side frame are hinged to the left and right ends of the upper horizontal frame via left and right pins, respectively. Two retraction drive cylinders are positioned above the upper horizontal frame with their cylinder ends close together. The cylinder ends of the two retraction drive cylinders are hinged to the upper ends of two supports fixed to the upper end of the upper horizontal frame via their respective pins. Specifically, the cylinder rod end of the left retraction drive cylinder is hinged to one end of the left pull rod and one end of the left support rod via a pin. The other end of the left pull rod is hinged to a connecting seat fixed to the left side frame via a pin, and the other end of the left support rod is rotatably connected to the left pin. The cylinder rod end of the right-side retraction drive cylinder is hinged to one end of the right pull rod 3.8 and one end of the right support rod 3.7 via a pin. The other end of the right pull rod is hinged to the connecting seat fixed on the right side frame via a pin. The other end of the right support rod is rotatably connected to the right pin. The spraying operation length of the aforementioned left and right section spray membrane plates is 1.4m.

[0026] Using this top-mounted spraying device, during aircraft spraying operations, the cylinder rods of the two retractable drive cylinders retract, driving the left spray membrane plate to rotate around the left pivot center and the right spray membrane plate around the right pivot center. This rotates the left and right spray membrane plates to a position on the same plane as the middle left and middle right spray templates. The overall spraying length can reach 4 meters, enabling large-area spraying operations. During the spraying operation on the aircraft surface, the orientation of the top spraying device can be adjusted by the upper hydraulic rotary motor, and the orientation of the middle lifting mechanism can be adjusted by the lower hydraulic rotary motor. Combined with the adjustment of the upper and lower drive cylinders and the extension length of the auxiliary arm, different parts of the aircraft can be sprayed and cleaned, improving cleaning efficiency, reducing labor intensity, and achieving better cleaning results.

[0027] When cleaning is not required, the middle lifting mechanism can be folded back using the upper and lower drive cylinders. At the same time, the cylinder rods of the two retraction drive cylinders extend to flip the left and right spray film plates downwards, thereby reducing the storage space of the spray aircraft cleaning vehicle.

[0028] In this invention, all drive cylinders are hydraulic cylinders, and all drive cylinders, the upper hydraulic rotary motor, and the lower hydraulic rotary motor are uniformly controlled by the same hydraulic pump station and proportional solenoid valve. The hydraulic control system is not shown in the accompanying drawings.

[0029] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
