Description

Technical Field

[0001] The utility model belongs to the technical field of UAV engine cleaning, and particularly relates to an adjustable air pressure blocker assembly. Background Technique

[0002] After the UAV engine runs for a period of time, carbon deposits will be generated in the combustion chamber. The carbon deposits will not only reduce the combustion efficiency of the fuel, resulting in increased fuel consumption, but also may adsorb fuel molecules, resulting in a decrease in power. Therefore, it is necessary to remove carbon deposits in the combustion chamber through a cleaning liquid and a pulse carbon remover.

[0003] Currently, when adjusting the air pressure in the combustion chamber through a cleaning liquid and a pulse carbon remover in cooperation with a blocker for carbon deposit cleaning in the combustion chamber, generally, the cleaning liquid is directly added into the combustion chamber, and the pulse carbon remover is started to work. The pulse carbon remover generates a high-pressure pulse air flow through a high-pressure air pulse generator and injects it into the components of the engine. Through the cooperation of the cleaning liquid and the high-pressure pulse air flow, the carbon deposits are separated, loosened, and shed through the impact force and vibration, thereby completing the cleaning. However, when cleaning the carbon deposits in the combustion chamber, since the cleaning liquid is directly added into the combustion chamber, after the carbon deposits in the combustion chamber are cleaned, due to the heavy weight of the engine, it is not convenient to pour out the cleaning liquid from the combustion chamber, so that the cleaning liquid is likely to remain in the combustion chamber, affecting the normal operation of the engine in the later stage. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable air pressure blocker assembly to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an adjustable air pressure blocker assembly, comprising:

[0006] An aluminum plate, a rubber plug is provided at the bottom of the aluminum plate, a washing pipe interface is provided at the top of the aluminum plate, and a long pipe is connected to the bottom of the washing pipe interface. One end of the long pipe penetrates through the aluminum plate and the rubber plug and is screwed with a wing nut through an external thread on the surface, so that the rubber plug is fixed to the bottom of the aluminum plate;

[0007] An exhaust pipe, the bottom of the rubber plug is inserted into the top of the exhaust pipe, and two sets of tightening clips are provided at the connection between the exhaust pipe and the rubber plug, and the two sets of tightening clips are screwed together through a tightening nut, so that the connection between the exhaust pipe and the rubber plug is fixed by tightening between the two sets of tightening clips.

[0008] Preferably, two sets of U-shaped screws are provided on the surface of the aluminum plate, and one end of the U-shaped screws is located at the bottom of the connection between the two sets of tightening clips.

[0009] Preferably, a U-shaped nut is threadedly connected to one end of the U-shaped screw located at the top of the aluminum plate.

[0010] Preferably, a cleaning pipe is connected to the surface of the pipe washing interface.

[0011] Preferably, a connecting pipe slidably penetrates through the surface of one set of tightening clamps, and the other end of the connecting pipe is connected to the exhaust pipe.

[0012] Preferably, soft pads are provided at the joints of the two sets of tightening clamps and the exhaust pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: First, the device is fixed on the exhaust pipe of the UAV engine through U-shaped screws and tightening clamps. This fixing method is simple and reliable, which can ensure that the device will not loosen or fall off during the cleaning process. Then, the cleaning pipe is connected to the cleaning liquid output pipeline, so that the cleaning liquid flows into the long pipe through the cleaning pipe, and then flows into the exhaust pipe through the long pipe. Finally, it flows into the combustion chamber through the exhaust pipe, inputting sufficient air pressure into the combustion chamber. By adjusting the air pressure, users can accurately control the magnitude of the input air pressure according to different cleaning requirements and engine conditions, ensuring that during the cleaning process, the cleaning liquid can flow through the combustion chamber of the engine at an appropriate pressure to achieve the best cleaning effect. When sufficient air pressure is input, the air pressure will push the cleaning liquid to flow inside the combustion chamber of the engine. The cleaning liquid enters from the combustion chamber of the engine and, under the action of the air pressure, passes through various parts of the engine. After circulating once, it dissolves and carries away dirt such as carbon deposits. Since the connecting pipe is connected to the pipeline of the combustion chamber, the cleaning liquid can only be discharged from the connecting pipe and leak out from the exhaust pipe, thus realizing the cleaning process. And the air pressure push avoids the residue of the cleaning liquid in the combustion chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] An aluminum plate 1, a rubber plug 2 is provided at the bottom of the aluminum plate 1, a washing pipe interface 3 is provided at the top of the aluminum plate 1, and a long pipe 4 is connected to the bottom of the washing pipe interface 3. One end of the long pipe 4 penetrates through the aluminum plate 1 and the rubber plug 2 and is screwed to a butterfly nut 5 through an external thread on the surface, so that the rubber plug 2 is fixed to the bottom of the aluminum plate 1;

[0021] An exhaust pipe 6, the bottom of the rubber plug 2 is inserted into the top of the exhaust pipe 6, and two sets of tightening clips 7 are provided at the connection between the exhaust pipe 6 and the rubber plug 2, and the two sets of tightening clips 7 are screwed together through a tightening nut 8, so that the connection between the two sets of tightening clips 7 is tightened to fix the connection between the exhaust pipe 6 and the rubber plug 2.

[0022] Two sets of U-shaped screws 9 are provided on the surface of the aluminum plate 1, and one end of the U-shaped screws 9 is located at the bottom of the connection between the two sets of tightening clips 7. The end of the U-shaped screws 9 located at the top of the aluminum plate 1 is threadedly connected to a U-shaped nut 10. By screwing the U-shaped nut 10, the end of the U-shaped screws 9 located at the bottom of the connection between the two sets of tightening clips 7 can tighten the tightening clips 7, strengthening the firmness of the connection between the rubber plug 2 and the exhaust pipe 6 and preventing liquid leakage.

[0023] A cleaning pipe 11 is connected to the surface of the washing pipe interface 3, and cleaning liquid can be injected into the long pipe 4 through the cleaning pipe 11.

[0025] Soft pads 13 are provided at the connection between the two sets of tightening clips 7 and the exhaust pipe 6, and the soft pads 13 protect the contact places between the tightening clips 7 and the exhaust pipe 6, avoiding abrasion of the exhaust pipe 6 when the tightening clips 7 clamp the exhaust pipe 6.

[0026] The adjustable air pressure blocker assembly first fixes the device on the exhaust pipe 6 of the UAV engine through the U-shaped screw 9 and the tightening clamp 7. This fixing method is simple and reliable, which can ensure that the device will not loosen or fall off during the cleaning process. Then, connect the cleaning pipe 11 to the cleaning liquid output pipeline, so that the cleaning liquid flows into the long pipe 4 through the cleaning pipe 11, and then flows into the exhaust pipe 6 through the long pipe 4. Finally, it flows into the combustion chamber through the exhaust pipe 6, inputting sufficient air pressure into the combustion chamber. By adjusting the air pressure, users can accurately control the magnitude of the input air pressure according to different cleaning requirements and engine conditions, ensuring that during the cleaning process, the cleaning liquid can flow through the combustion chamber of the engine at an appropriate pressure to achieve the best cleaning effect. When sufficient air pressure is input, the air pressure will push the cleaning liquid to flow inside the combustion chamber of the engine. The cleaning liquid enters from the combustion chamber of the engine and, under the action of the air pressure, passes through various parts of the engine. After circulating once, it dissolves and carries away dirt such as carbon deposits. Since the connecting pipe 12 is connected to the pipeline of the combustion chamber, the cleaning liquid can only be discharged from the connecting pipe 12 and leak out from the exhaust pipe 6, thus realizing the cleaning process. The air pressure push avoids the residue of the cleaning liquid in the combustion chamber.
