[0040] Reference Figure 8 , the first adjustment component includes a threaded rod 28 rotatably connected to the top of the water outlet shell 25, the outer wall of the threaded rod 28 is threadedly connected with a lifting plate 29, the bottom of the lifting plate 29 is fixedly connected with a baffle 30 slidably inserted in the water outlet shell 25, and the partition 26 is provided with a through opening 31, and the baffle 30 is inserted in part of the through opening 31; when it is necessary to make the scattering component adapt to engine blades of different sizes, the threaded rod 28 is rotated, the threaded rod 28 drives the lifting plate 29 to move, and the lifting plate 29 drives the baffle 30 to move in the vertical direction, so that the baffle 30 moves in the through opening 31 of the partition 26, and the baffle 30 can increase or decrease the number of water outlet areas 27 from which the cleaning agent can be sprayed. If the number of water outlet areas 27 from which the cleaning agent can be sprayed is increased, the spraying range of the water outlet shell 25 is increased, and if the number of water outlet areas 27 from which the cleaning agent can be sprayed is reduced, the spraying range of the water outlet shell 25 is reduced.

[0041] Reference Figure 7 and Fig. 9, the second adjustment component includes a hose 37 fixed to one end of the water spray pipe 3, one end of the hose 37 is fixed to a hard tube 36, the outer wall of the hard tube 36 is slidably connected to a moving ring 35, a rotating block 34 is fixed to the moving ring 35, a vertical rod 32 is fixed to the lifting plate 29, a U-shaped seat 33 is fixed to the top of the vertical rod 32, and the U-shaped seat 33 is rotatably connected to the rotating block 34 through a rotating shaft; when it is necessary to adjust the angle of the nozzle 4 to adapt to engine blades of different sizes, if the engine blade size is large, the rotating threaded rod 28 drives the lifting plate 29 to move upward, which can increase the spraying range of the scattering component on the one hand, the lifting plate 29 drives the U-shaped seat 33 to move upward through the vertical rod 32, and the U-shaped seat 33 drives the hard tube 36 and the nozzle 4 to rotate upward through the rotating block 34 and the moving ring 35, so that the angle between the nozzle 4 and the horizontal plane is increased, and if the engine blade size is small, the threaded rod 28 can be rotated in the opposite direction to achieve the purpose of adjusting the angle of the nozzle 4 according to the engine blade size.

[0042] Reference Fig. 9 One end of the hard tube 36 is rotatably connected to a rotating head 38, and the nozzle 4 is mounted on the rotating head 38. The center line of the rotating head 38 is on the same line as the center line of the hard tube 36, and the center line of the nozzle 4 is not on the same line as the rotating head 38. A fixing rod 39 is fixedly connected to the inner wall of the rotating head 38, and a rotating shaft 40 is fixedly connected to the fixing rod 39. A plurality of fan blades 41 are fixedly connected to the outer wall of the rotating shaft 40. In the process of the cleaning agent passing through the hard tube 36, the cleaning agent can drive the fan blades 41 to rotate, and the fan blades 41 drive the rotating shaft 40 to rotate. The rotating shaft 40 drives the rotating head 38 to rotate through the fixing rod 39. The rotation of the rotating head 38 can drive the nozzle 4 to rotate. Since the center line of the nozzle 4 is not on the same line as the rotating head 38, the rotation of the nozzle 4 can increase its spraying range, which is beneficial to the cleaning of the engine blades.

[0043] Working principle: when in use, move the device body 1 to the engine to be cleaned, extend the water spray pipe 3 and the mounting plate 2 into the engine, make the cleaning component act on the bottom inner wall of the engine, make the nozzle 4 face the root of the engine blades, start the water pump to spray the cleaning agent to the engine blades through the water spray pipe 3 and the nozzle 4, and spray the engine blades as a whole through the scattering component. The scattering range of the scattering component can be adjusted through the first adjustment component so that the scattering component can adapt to engine blades of different sizes. The angle of the nozzle 4 can be adjusted through the second adjustment component so that the nozzle 4 can adapt to blade roots of different heights. During the spraying of the cleaning agent, part of the cleaning agent will fall onto the bottom inner wall of the engine. The cleaning component can cooperate with the fallen cleaning agent to contact and clean the bottom inner wall of the engine, and clean the dirt and carbon deposits deposited on the bottom inner wall of the engine.

[0044] When it is necessary to clean the dirt and carbon deposits deposited on the inner wall of the bottom of the engine, the motor 5 is started, and the motor 5 drives the rotating column 6 and the conveyor belt 7 to run. The conveyor belt 7 can drive the sponge block 9 and the brush bundle 10 to move through the flat plate 8. The sponge block 9 can absorb the fallen cleaning agent and transport the cleaning agent out of the engine to prevent the cleaning agent from being deposited on the inner wall of the bottom of the engine. The brush bundle 10 can cooperate with the fallen cleaning agent to clean the bottom of the engine and clean the deposited dirt and carbon deposits out of the engine.

[0045] When the conveyor belt 7 drives the brush bundle 10 to move through the flat plate 8, the brush bundle 10 drives the connecting plate 12 and the top column 13 to move, so that the top column 13 moves on the surface of the wave block 14. During the movement of the top column 13, the wave block 14 can drive the connecting plate 12 to move back and forth through the concave area 1401 and the convex area 1402, and the connecting plate 12 can drive the row of brush bundles 10 to move back and forth. The reciprocating movement of the brush bundle 10 can clean the inner wall of the bottom of the engine;

[0046] During the movement of the sponge block 9, the sponge block 9 will contact the pressure roller 19 when passing through it, and the pressure roller 19 can squeeze the sponge block 9. The spring 18 provides squeezing force, and the cleaning agent in the sponge block 9 will be squeezed out. The brush bundle 10 will also contact the pressure roller 19 when passing through it. The pressure roller 19 can bend the brush bundle 10, and the impurities and dirt retained in the brush bundle 10 will fall out. The cleaning agent squeezed out of the sponge block 9 by the pressure roller 19 will fall onto the brush bundle 10 below, and the cleaning agent can rinse the brush bundle 10.

[0047] When the conveyor belt 7 drives the brush bundle 10 to move through the flat plate 8, the fixed column 22 corresponding to the brush bundle 10 will contact the arc plate 21. The fixed column 22 continues to move to press the arc plate 21. The arc plate 21 drives the U-shaped plate 17 to move through the fixed plate 20. The spring 18 is compressed, and the U-shaped plate 17 drives the pressure roller 19 to move. When the fixed column 22 passes through the arc plate 21, the pressure roller 19 suddenly resets under the action of the spring 18. The pressure roller 19 can impact the brush bundle 10 and make the brush gap between the brush bundles 10 larger, which is conducive to the impurities and dirt in the brush bundle 10 falling out. By setting the annular groove 23, the brushes of the brush bundle 10 can enter the annular groove 23 to remove the impurities attached to the brushes.

[0048] When the cleaning agent passes through the water spray pipe 3, the cleaning agent can enter the water outlet housing 25 through the connecting pipe 24. The cleaning agent entering the water outlet housing 25 will be diverted to each water outlet area 27 by the partition 26. The cleaning agent is sprayed out from multiple water outlet areas 27, and the sprayed cleaning agent is evenly sprayed onto the engine blades in a scattered state.

[0049] When it is necessary to adapt the scattering assembly to engine blades of different sizes, the threaded rod 28 is rotated, the threaded rod 28 drives the lifting plate 29 to move, and the lifting plate 29 drives the baffle 30 to move in the vertical direction, so that the baffle 30 moves in the opening 31 of the partition 26. The baffle 30 can increase or decrease the number of water outlet areas 27 from which the cleaning agent can be sprayed. If the number of water outlet areas 27 from which the cleaning agent can be sprayed is increased, the spraying range of the water outlet shell 25 is increased. If the number of water outlet areas 27 from which the cleaning agent can be sprayed is reduced, the spraying range of the water outlet shell 25 is reduced.

[0050] When the angle of the nozzle 4 needs to be adjusted to adapt to engine blades of different sizes, if the engine blade is large, the threaded rod 28 is rotated to drive the lifting plate 29 to move upward, which can increase the spraying range of the scattering component. The lifting plate 29 drives the U-shaped seat 33 to move upward through the vertical rod 32, and the U-shaped seat 33 drives the hard tube 36 and the nozzle 4 to rotate upward through the rotating block 34 and the moving ring 35, so that the angle between the nozzle 4 and the horizontal plane is increased. If the engine blade is small, the threaded rod 28 can be rotated in the opposite direction to achieve the purpose of adjusting the angle of the nozzle 4 according to the size of the engine blade;

[0051] When the cleaning agent passes through the hard tube 36, the cleaning agent can drive the fan blades 41 to rotate, the fan blades 41 can drive the rotating shaft 40 to rotate, the rotating shaft 40 can drive the rotating head 38 to rotate through the fixed rod 39, and the rotation of the rotating head 38 can drive the nozzle 4 to rotate. Since the center line of the nozzle 4 is not on the same line as the rotating head 38, the rotation of the nozzle 4 can increase its spraying range, which is beneficial to the cleaning of the engine blades.
