Description

Technical Field

[0001] This utility model belongs to the field of cleaning device technology, and in particular relates to an oil removal and cleaning device for aerospace parts. Background Technology

[0002] In the aerospace field, the cleanliness of piping systems is directly related to flight safety and equipment reliability. These systems mainly include fuel system piping, hydraulic system piping, cooling system piping, oxygen system piping, and propellant delivery piping.

[0003] Accumulated deposits or oil stains in pipelines reduce pipeline efficiency and increase usage risks. Existing cleaning methods for long straight pipelines use high-pressure spraying or pulse cleaning, but the cleaning fluid tends to form laminar flow in long straight pipelines, resulting in insufficient turbulence and ineffective flushing of deposits. In addition, some pipelines have weld seams, where deposits tend to remain in uneven areas, affecting the cleaning quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to clean the attachments on long straight pipes, increase the comprehensiveness of the cleaning of the inner wall of the pipe, and improve the cleaning quality of the inner wall of the pipe.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an aerospace component degreasing and cleaning device, comprising a support pipe, a support assembly, a sealing mechanism, and a nozzle. The support assembly is fixedly connected to one end of the support end. The sealing mechanism is located on the outer wall of the support pipe and close to the support assembly. The nozzle penetrates the outer wall of the support pipe and is connected to the support pipe. The other end of the support pipe is provided with an mounting plate. A liquid inlet assembly is provided inside the support pipe to supply cleaning fluid to the nozzle.

[0006] Furthermore, the support assembly includes a first airbag and an air pump. The first airbag is fixedly connected to the end of the support tube away from the mounting plate. The air pump is fixedly connected to the mounting plate, and the air outlet of the air pump is connected to the internal pipeline of the support tube. The outer circumference of the first airbag is hinged with a support wheel.

[0007] Furthermore, the sealing mechanism includes a second airbag, which is fixedly connected to the outer wall of the support tube near the end of the first airbag, and a connecting tube connects the second airbag and the first airbag.

[0008] Furthermore, the second airbag has through holes on its outer circumference, the through holes being arranged in a ring at uniform intervals, and rubber valves being provided inside the through holes. A scraper is fixedly connected to the outer circumference of the second airbag, the scraper being symmetrically distributed with left and right offsets, and the scraper is made of silicone material.

[0009] Furthermore, the liquid inlet assembly includes a connecting box, a liquid inlet pipe, and a water pump. The connecting box is fixedly connected to the liquid inlet end of the nozzle and located inside the support pipe. The water pump is fixedly connected to the mounting plate, and the liquid inlet pipe connects the output end of the water pump to the connecting box.

[0010] Furthermore, the diameter of the first airbag is smaller than the diameter of the second airbag.

[0011] After adopting the above structure, the beneficial effects of this utility model are as follows: For cleaning long straight pipe parts used in various pipeline systems of aerospace, a support pipe of appropriate length is inserted, and a support component moves at the front end to support and keep the support pipe coaxial with the pipe, supplying air to the inside of the first airbag to make it expand, and the support wheel on the outer circumference moves against the inner wall of the pipe.

[0012] The water pump is connected to the external cleaning fluid at the input end and is delivered to each nozzle through the inlet pipe. The nozzle sprays the cleaning fluid outward from the front end of the support pipe, so that the cleaning fluid impacts the inner wall of the pipe radially.

[0013] At the same time, after the first airbag inflates, gas enters the second airbag, causing the second airbag to inflate, blocking the pipe and preventing the cleaning fluid from flowing back. Gas is also ejected through the through-hole on the outer circumference of the second airbag, acting on the inner wall of the pipe and blowing the front end of the cleaning fluid, causing it to flow through the gap between the first airbag and the pipe, thus increasing the cleaning quality.

[0020] like Figure 1-4 As shown, an aerospace component degreasing and cleaning device includes a support pipe 1, a support assembly 2, a sealing mechanism 3, and a nozzle 4. The support assembly 2 is fixedly connected to one end of the support pipe. The sealing mechanism 3 is located on the outer wall of the support pipe 1 and close to the support assembly 2. The nozzle 4 penetrates the outer wall of the support pipe 1 and is connected to the support pipe 1. The other end of the support pipe 1 is provided with an mounting plate 5. A liquid inlet assembly 6 is provided inside the support pipe 1 to supply cleaning fluid to the nozzle 4. The support assembly 2 is at the front end of the support pipe 1 and extends into the pipe. Through the expansion of the support assembly 2 and the sealing mechanism 3, the support pipe 1 and the pipe are made nearly coaxial. At the same time, the sealing mechanism 3 seals the pipe on the rear side of the support assembly 2 to prevent the cleaning fluid from flowing back. The liquid inlet assembly 6 draws external cleaning fluid and delivers it to the nozzle 4. The nozzle 4 radially impacts the inner wall of the pipe to achieve pipe cleaning.

[0021] like Figure 2 and Figure 4 As shown, in order to provide cleaning fluid to the nozzle 4, the liquid inlet assembly 6 includes a connecting box 15, a liquid inlet pipe 16 and a water pump 17. The connecting box (15) is fixedly connected to the liquid inlet end of the nozzle 4 and is located inside the support pipe 1. The water pump 17 is fixedly connected to the mounting plate 5. The liquid inlet pipe 16 connects the output end of the water pump 17 and the connecting box 15. The water pump 17 draws external cleaning fluid, delivers it to the connecting box 15 through the liquid inlet pipe 16, and then passes it into each nozzle 4 through the connecting box 15 to realize the spraying of cleaning fluid.

[0022] like Figure 2-4 As shown, in order to improve the coaxiality of the support tube 1 and the pipeline, the support assembly 2 includes a first airbag 7 and an air pump 8. The first airbag 7 is fixedly connected to the end of the support tube 1 away from the mounting plate 5. The air pump 8 is fixedly connected to the mounting plate 5, and the air outlet of the air pump 8 is connected to the internal pipeline of the support tube 1. The outer circumference of the first airbag 7 is hinged with a support wheel 9. The air pump 8 draws in external air and delivers gas to the first airbag 7 at the front end through the support tube 1, causing the first airbag 7 to expand and increase in diameter. The support wheel 9 preferentially contacts the inner wall of the pipeline, which facilitates the movement of the first airbag 7 at the front end.

[0023] like Figure 1-4As shown, in order to enable the cleaning fluid to move in the feed direction of the device within the pipeline while preventing backflow of the cleaning fluid, the sealing mechanism 3 includes a second airbag 10. The second airbag 10 is fixedly connected to the outer wall of the support pipe 1 near the end of the first airbag 7. A connecting pipe 11 connects the second airbag 10 and the first airbag 7. The diameter of the first airbag 7 is smaller than the diameter of the second airbag 10. The second airbag 10 is connected to the first airbag 7 through the connecting pipe 11. After the gas enters the second airbag 10 through the first airbag 7, the second airbag 10 expands and contacts the inner wall of the pipeline first, thus sealing the cleaning fluid and preventing backflow.

[0024] The second airbag 10 has through holes 12 on its outer circumference. The through holes 12 are arranged in a ring with uniform intervals. A rubber valve 13 is provided inside the through holes 12. A scraper 14 is fixedly connected to the outer circumference of the second airbag 10. The scraper 14 is symmetrically distributed with left and right staggered arrangement. The scraper 14 is made of silicone. After the second airbag 10 is inflated, the gas expands the rubber valve 13 on its outer circumference and sprays out through the through holes 12. It acts on the inner wall of the pipe and works with the scraper 14 to contact the inner wall of the pipe, assisting in cleaning the inner wall of the pipe and scraping off the cleaning fluid. At the same time, the gas enters between the first airbag 7 and the second airbag 10, pushing the cleaning fluid forward and causing the cleaning fluid to flow out between the outer circumference of the first airbag 7 and the inner wall of the pipe, increasing the flow rate of the cleaning fluid and improving the cleaning effect at the front end.

[0025] In actual use, the operator takes the support tube 1, inserts the front support mechanism into the pipe, and drives the air pump 8 to deliver gas into the first airbag 7. The first airbag 7 expands and its diameter increases. The support wheel 9 contacts the inner wall of the pipe first, which facilitates the movement of the first airbag 7 at the front end. At the same time, the gas in the first airbag 7 enters the second airbag 10 through the connecting pipe 11, causing the second airbag 10 to expand. The first airbag 7 and the second airbag 10 provide support for the support tube 1, so that the support tube 1 and the pipe remain coaxial.

[0026] During cleaning, the water pump 17 draws external cleaning fluid and delivers it to the connecting box 15 through the inlet pipe 16. The fluid is then introduced into each nozzle 4 through the connecting box 15 to achieve spraying and rinsing of the cleaning fluid.

[0027] Simultaneously, after the second airbag 10 inflates, it contacts the inner wall of the pipe before the first airbag 7, sealing the cleaning fluid and preventing backflow. Gas expands the rubber valve 13 on the outer circumference of the second airbag 10, and gas is ejected through the through hole 12, acting on the inner wall of the pipe. It works in conjunction with the scraper 14 to contact the inner wall of the pipe, assisting in cleaning the inner wall of the pipe and scraping off the cleaning fluid. At the same time, gas enters between the first airbag 7 and the second airbag 10, pushing the cleaning fluid forward, so that the cleaning fluid flows out between the outer circumference of the first airbag 7 and the inner wall of the pipe, increasing the flow rate of the cleaning fluid and improving the cleaning effect at the front end.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
