Description

Technical Field

[0001] The utility model relates to the technical field of aviation fuel tank cleaning, in particular to an ultrasonic high-efficiency cleaning device for aviation fuel tanks. Background Technique

[0002] Aviation fuel tanks are indispensable equipment in the general aviation field and are used to store important materials such as aviation fuel. Since aviation fuel has extremely high requirements for quality assurance measures, it is particularly important to regularly clean and maintain the fuel tanks. The ultrasonic high-efficiency cleaning device has become the preferred technology for cleaning aviation fuel tanks due to its remarkable cleaning effect and environmental protection characteristics. Ultrasonic cleaning utilizes the cavitation effect, acceleration effect, and rectilinear flow effect of ultrasonic waves in liquids to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off to achieve the cleaning purpose. In the currently used ultrasonic cleaning machines, the cavitation effect and rectilinear flow effect are more applied. Crude oil is relatively viscous, so it is not easy to clean the oil tanks storing crude oil, and ultrasonic waves need to be used for cleaning. However, there are certain defects in the existing ultrasonic cleaning devices. The existing cleaning devices often only have the function of cleaning and cannot adsorb the residual crude oil washed down. Often, the washed-down residues are directly poured away, resulting in a certain waste.

[0003] The prior art patent CN216323817U discloses an ultrasonic high-efficiency cleaning device for crude oil tanks, including an oil tank and a mounting cover. The lower surface of the oil tank is fixedly installed with support columns. One side of the lower surface of the oil tank is provided with an oil outlet. The lower surface of the mounting cover is fixedly installed with a cylinder. The lower surface of the cylinder is fixedly installed with a protective cover. The lower surface of the protective cover is fixedly installed with a collection bin. The outer surface of the collection bin is provided with a notch.

The lower end of the rotating column is fixedly installed with a body. The outer surface of the rotating column is fixedly installed with a mounting rack. This prior art makes the cleaning device have a recycling function. The residual crude oil washed down can be adsorbed on the surface of the adsorption net. After the cleaning is completed, the adsorption net can be directly disassembled, and then the adsorbed crude oil can be collected, which is practical.

[0004] However, in the above prior art, the adsorption net is clamped in the mounting rack. Due to the clamping method, it is extremely easy for the adsorption net to fall out during the rotation of the mounting rack, thereby affecting the cleaning effect. Content of the Utility Model

Detailed implementation mode

[0020] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0021] Please refer to Figures 1 to 6 , the present invention provides an ultrasonic high - efficiency cleaning device for aviation fuel storage tanks, including an installation cover 1 and a plurality of fixing mechanisms. The inner top of the installation cover 1 is provided with a cylinder 2, the output end of the cylinder 2 is provided with a motor 3, the output end of the motor 3 is provided with a rotating column 4, the outside of the rotating column 4 is provided with a plurality of mounting frames 5, the mounting frames 5 are internally clamped with an adsorption net 6, and the ultrasonic body 7 is arranged below the rotating column 4. By clamping the adsorption net 6 inside the mounting frame 5 and placing the device above the oil tank, the output end of the cylinder 2 partially extends into the oil tank. The cylinder 2 can adjust the height of the plurality of mounting frames 5, and the ultrasonic body 7 will operate to emit ultrasonic waves to clean the oil tank. Then the motor 3 will drive the rotating column 4 to rotate, and the adsorption net 6 will adsorb the residues for collection.

[0022] For this specific embodiment, a plurality of the fixing mechanisms are respectively arranged on the corresponding mounting frame 5. The fixing mechanism includes a plurality of rectangular rods 8 and a fixing frame 9. One end of the rectangular rod 8 is provided with an anti - detachment block 10, and the other end of the rectangular rod 8 is provided with a bottom plate 11. A spring 12 is sleeved on the rectangular rod 8. A holding frame 13 is arranged on the fixing frame 9. Rectangular grooves 14 are provided at the four bottom corners of the fixing frame. A plurality of the rectangular rods 8 are respectively slidably connected to the mounting frame 5 and are located in the corresponding rectangular grooves 14. And the spring 12 abuts between the mounting frame 5 and the bottom plate 11. The fixing frame 9 is engaged with the mounting frame 5 and is located inside the mounting frame 5. And the holding frame 13 abuts against the adsorption net 6. The anti - detachment block 10 abuts against the fixing frame 9 and is located at the bottom corner of the fixing frame 9. The adsorption net 6 is secondarily fixed by the fixing frame 9. The situation that the fixing frame 9 comes off can be prevented by the arrangement of the rectangular rod 8 and the anti - detachment block 10. Finally, the spring 12 plays a role in pulling the rectangular rod 8, thereby effectively improving the stability when the adsorption net 6 is fixed, so as to avoid reducing the cleaning effect.

[0023] Wherein, the fixing mechanism further includes a plurality of anti - slip pads 15. A plurality of the anti - slip pads 15 are respectively adhered to the corresponding bottom plates 11 and are located at one end of the bottom plate 11 away from the rectangular rod 8. The anti - slip pads 15 can facilitate the pushing of the rectangular rod 8, thereby preventing the situation of slipping when the rectangular rod 8 is pressed.

[0024] Secondly, a T - shaped block 16 is arranged on one side of the mounting frame 5. A plurality of T - shaped grooves 17 are provided on the outer side of the rotating column 4. The T - shaped block 16 is slidably connected to the rotating column 4 and is located in the corresponding T - shaped groove 17. The arrangement of the T - shaped block 16 can facilitate the disassembly of the mounting frame 5, thereby facilitating the timely replacement of the damaged mounting frame 5 subsequently.

[0025] Thirdly, a screw rod 18 is arranged above the ultrasonic wave body 7. A threaded groove 19 is provided below the rotating column 4. And the screw rod 18 is in threaded connection with the rotating column 4 and is located in the threaded groove 19. The arrangement of the screw rod 18 and the threaded groove 19 can facilitate the quick disassembly and assembly of the ultrasonic wave body 7. At the same time, it also plays a role in limiting the mounting frame 5 to prevent the T - shaped block 16 from sliding out of the T - shaped groove 17.

[0026] In addition, the ultrasonic high-efficiency cleaning device for aviation fuel storage tanks further includes a fixing ring 20 and a plurality of electric push rods 21. The output end of the electric push rod 21 is provided with an arc-shaped seat 22. The fixing ring 20 is fixedly connected to the corresponding electric push rod 21 and sleeved on the plurality of electric push rods 21. The plurality of electric push rods 21 are respectively fixedly connected to the mounting cover 1 and located above the mounting cover 1. Moreover, the output end of the electric push rod 21 penetrates through the mounting cover 1. By means of the electric push rod 21, it is convenient to adjust the height of the device on the oil tank, so that the adsorption net 6 can be adjusted to a position that the cylinder 2 cannot reach, thereby improving the cleaning range.

[0027] When installing the adsorption net 6 using the present utility model, by pressing two of the rectangular rods 8, the rectangular rods 8 move the anti-detachment block 10 away from the mounting bracket 5. Then, the adsorption net 6 and the fixing frame 9 are placed together between two corresponding rectangular rods 8 and slide into the space between the other two rectangular rods 8. At the same time, press the other two rectangular rods 8 to move the adsorption net 6 and the fixing frame 9 between the plurality of rectangular rods 8. At this time, the adsorption net 6 and the fixing frame 9 are engaged within the mounting bracket 5. Finally, release the rectangular rods 8, and the rectangular rods 8 are reset under the action of the spring 12, so that the anti-detachment block 10 abuts against the fixing frame 9, thereby preventing the adsorption net 6 from falling out. In this way, the technical problem that the adsorption net 6 is engaged within the mounting bracket 5 and is extremely likely to fall out during the rotation of the mounting bracket 5 due to the engagement method, thus affecting the cleaning effect, is solved.

[0028] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of rights of the present utility model. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
