An inclined groove 25 is provided at the bottom of the driving seat 24 near the side of the housing 1, and a triangular block 26 is fixed to the top of the bracket 39, and the triangular block 26 is located below the inclined groove 25;

[0045] A contraction mechanism 12, the contraction mechanism 12 is used for contracting the connecting rope 36;

[0046] When cleaning the bottom of the ship, the water flow drives the blades 41 to rotate the circular tube 9, and the circular tube 9 drives the crushing ball 37 to rotate through the connecting rope 36, so as to break the shells of the shellfish attached to the bottom of the ship. After breaking, the moving bracket 39 makes the outer shell 1 close to the hull. During the movement of the bracket 39, the triangular block 26 squeezes the driving seat 24 so that the retracting mechanism 12 drives the connecting rope 36 to retract, and the crushing ball 37 fits the surface of the circular tube 9. At this time, the cleaning member 11 contacts the bottom of the ship, and the cleaning member 11 is used to clean the broken shellfish.

[0047] like Figure 2 As shown, in this embodiment, the driving assembly 23 also includes a tension spring 27, and protrusions 43 are fixed on both sides of the driving seat 24. The tension spring 27 is fixed between the protrusion 43 and the outer shell 1. When the driving seat 24 moves toward the outer shell 1, the tension spring 27 can stably pull the driving seat 24 to move, thereby preventing the driving seat 24 from getting stuck.

[0048] like Figure 2 As shown, in this embodiment, a positioning rod 28 is movably inserted into the protrusion 43, the positioning rod 28 is fixed to the surface of the housing 1, and the tension spring 27 is sleeved on the surface of the positioning rod 28. The positioning rod 28 guides the driving seat 24 to make the driving seat 24 more stable during movement.

[0049] like Fig.10 As shown, in this embodiment, a crushing convex ring 38 is fixed on the surface of the crushing ball 37. The crushing convex ring 38 can reduce the area of ​​contact with the object, thereby increasing the impact force between the crushing ball 37 and the shell, and crushing is faster and more thorough. Secondly, the crushing convex ring 38 can help the crushing ball 37 to better disperse the impact force and improve the durability of the crushing ball 37.

[0050] like Figure 2 and Fig.11 As shown, in this embodiment, vertical plates 29 are fixed to the ends of the shell 1, horizontal plates 30 are fixed to the bottom of the vertical plates 29, and plug plates 33 are movably penetrated on the top of the horizontal plates 30. The plug plates 33 are fixed to the top of the bracket 39. A positioning hole 1 31 and a positioning hole 2 32 are opened on the vertical plate 29. The positioning hole 1 31 is located below the positioning hole 2 32. A positioning bolt 34 is threadedly connected to the side of the vertical plate 29. When the positioning bolt 34 is inserted into the positioning hole 1 31, the crushing ball 37 cleans the bottom of the ship. When the positioning bolt 34 is inserted into the positioning hole 2 32, the cleaning member 11 cleans the bottom of the ship. The end of the positioning bolt 34 is hemispherical, and the spherical surface guides the positioning bolt 34, so that the positioning bolt 34 is convenient for inserting into the positioning hole 1 31 and the positioning hole 2 32. The inner walls of the positioning hole 1 31 and the positioning hole 2 32 are both hemispherical.

[0051] like Figure 3 As shown, in this embodiment, the cleaning member 11 is a steel wire bristle, which has a harder structure, a better cleaning effect on dirt, and is more wear-resistant.

[0052] like Figure 7 As shown, in this embodiment, the retraction mechanism 12 includes a plurality of slide rails 15 fixed on the rotating shaft 8, and sliders 19 are slidably connected to the plurality of slide rails 15. A connecting plate 20 is fixed on the top of the slider 19. A connecting rope 36 movably passes through the round tube 9 and is fixed on the surface of the connecting plate 20. A plurality of guide rods 22 movably pass through the surface of the connecting plate 20, and the plurality of guide rods 22 are fixed in the round tube 9. A plurality of springs 21 are fixed between the connecting plate 20 and the round tube 9, and the springs 21 are sleeved on the surfaces of the guide rods 22. By setting the guide rods 22, when the connecting plate 20 is moving, the guide rods 22 can guide the connecting plate 20, so that the connecting plate 20 is more stable during movement. When the connecting plate 20 needs to retract inward, the elastic force of the springs 21 can drive the connecting plate 20 to retract, thereby further improving the stability of the connecting plate 20 during movement.

[0053] like Figure 7 As shown, in this embodiment, the slide rail 15 is composed of a vertical portion 16, an inclined portion 18 and a vertical portion 2 17 in sequence. The length of the vertical portion 2 17 is greater than that of the vertical portion 16. The slider 19 is slidably connected to the surface of the inclined portion 18. The fixed sleeve on the rotating shaft 8 is sleeved with a guide sleeve 13. The surface of the guide sleeve 13 is provided with a guide surface 14. The guide surface 14 has the same inclination angle as the inclined portion 18. The bottom of the slider 19 is provided with an inclined surface, and the inclination angle of the inclined surface is the same as that of the guide surface 14. The inclined surface at the bottom of the slider 19 is against the surface of the guide surface 14. The slider 19 can slide on the slide rail 15. When the slider 19 slides upward, the slider 19 can drive the connecting plate 20 to expand outward, and at the same time, the crushing ball 37 moves outward. When the slider 19 slides downward, the slider 19 can drive the connecting plate 20 to shrink inward, so that the crushing ball 37 fits the surface of the circular tube 9.

[0054] like Figure 1 As shown, in this embodiment, a handle 1 2 and a handle 2 3 are fixed to the surface of the housing 1. The double handles allow the left hand and the right hand to grasp the handle 1 2 and the handle 2 3 respectively, which is more stable during use.

The bending portion 14 can guide the dirt after cleaning to prevent the dirt from splashing onto the user, thereby protecting the user. Secondly, the bending portion 25 is more prominent than the bending portion 4. When the bending portion 25 is attached to the bottom of the ship, there is still a gap between the bending portion 4 and the bottom of the ship. After the bending portion 25 is attached to the bottom of the ship, the moisture and residual dirt after cleaning the bottom of the ship can be cleaned off, thereby improving the cleaning ability.

[0056] Working principle: connected to the water inlet 6 through the water delivery pipe, when cleaning the shellfish on the bottom of the ship, hold the handle 1 2 and the handle 2 3, and fit the outer shell 1 to the bottom of the ship through the positioning wheel 40 on the bracket 39, and then start the high-pressure water pump. The high-pressure water of the high-pressure water pump enters the water inlet 6 from the water delivery pipe and enters the circular tube 9. After the high-pressure water contacts the blade 41, it will drive the blade 41 to rotate. The rotation of the blade 41 will drive the circular tube 9 to rotate through the connecting rod 42. After the circular tube 9 rotates, it will drive the connecting rope 36 on the surface of the circular tube 9 to rotate. The connecting rope 36 will drive the crushing ball 37 and the crushing convex ring 38 on the surface of the crushing ball 37 to rotate. The shellfish shells are crushed by the rotating crushing ball 37 and the crushing convex ring 38.

[0057] After crushing, the positioning bolt 34 is moved out of the positioning hole 1 31, and the housing 1 is pressed downward. The fixing bolt is moved from the positioning hole 1 31 to the positioning hole 2 32, and the fixing bolt is inserted into the positioning hole 2 32. At the same time, the bracket 39 moves upward. During the upward movement of the bracket 39, the bracket 39 will drive the triangular block 26 to move upward, and the inclined surface of the triangular block 26 will abut against the inclined groove 25. During the upward movement of the triangular block 26, the inclined groove 25 slides downward along the inclined surface of the triangular block 26. During the sliding, the drive seat 24 moves away from the housing 1, and the drive seat 24 will drive the shaft 8 to move outward. During the upward movement of the shaft 8, the shaft 8 drives the slide rail 15 The slider 19 will slide downward on the inclined portion 18 and the guide surface 14 of the guide sleeve 13, and the slider 19 will drive the connecting plate 20 to shrink toward the center of the circular tube 9. The connecting plate 20 will drive the connecting rope 36 to shrink inward until the crushing ball 37 is retracted to the surface of the circular tube 9. At this time, the cleaning member 11 is in contact with the bottom of the ship. Then the high-pressure water pump is started again to drive the cleaning member 11 to clean the bottom of the ship through the circular tube 9. Secondly, the outer shell 1 after adjustment is in motion, and the bending portion 25 of the outer shell 1 is attached to the bottom of the ship. The moisture on the bottom of the ship can be scraped off through the bending portion 25, and the residual dirt can also be scraped off to improve the cleaning effect.

[0058] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
