[0020] For further information, see Figure 2 A hinge assembly 5 is arranged between the shell 1 and the aluminum tube 2. The hinge assembly 5 includes a lower cover 52 welded to the top of the shell 1. A lower hemispherical groove 521 is arranged in the lower cover 52. A lower slide groove 522 is arranged on the inner side of the lower hemispherical groove 521 in a vertical direction. The upper side of the lower hemispherical groove 521 is connected to the upper hemispherical groove 511. An upper slide groove 512 is arranged on the inner side of the upper hemispherical groove 511 in a vertical direction. The ends of the upper slide groove 512 and the lower slide groove 522 overlap. The upper hemispherical groove 511 is arranged in the upper cover 51. The upper cover 51 and the lower cover 52 are fixedly connected by bolts. A ball joint 21 is provided at the lower end of the aluminum tube 2, and the ball joint 21 is rotatably provided in the lower hemispherical groove 521 and the upper hemispherical groove 511. A slide bar 22 is provided on the side of the ball joint 21, and the slide bar 22 slides in the upper slide groove 512 and the lower slide groove 522. Through the provision of the hinge assembly 5, the angle between the shell 1 and the aluminum tube 2 can be adjusted arbitrarily, so that the grille 4 at the lower end of the shell 1 can be adjusted at an angle arbitrarily to adapt to the changes in the ground at the bottom of the warehouse, and the grille 4 is kept parallel to the ground at the bottom of the warehouse, so as to facilitate the suction of water when there is relatively little water. Through the sliding of the slide bar 22 in the upper slide groove 512 and the lower slide groove 522, the aluminum tube 2 and the hinge assembly 5 can be relatively fixed in the circumferential direction, and the hinge assembly 5 is prevented from rotating along the axis of the aluminum tube 2.

[0021] For further information, see Figure 3-Figure 5 The center of the upper side of the grille 4 is rotatably connected to a rotating disk 42, which is coaxially fixedly connected to a scraper rod 44, which is arranged at the lower side of the grille 4; the rotating disk 42 is axially evenly distributed with a plurality of spokes 421, and a slope 422 is arranged at the lower side of the spokes 421. When the water flows through the grille 4 during operation, the water flows will impact the slope 422, pushing the rotating disk 42 to rotate, and the rotating disk 42 drives the scraper rod 44 to rotate, scraping the lower surface of the grille 4 to prevent the through holes of the grille 4 from being blocked by debris.

[0022] For further information, see Figure 3-Figure 7 , gear teeth are arranged on the outer periphery of the rotating disk 42, the rotating disk 42 is meshed and connected with the upper pinion 43 through the gear teeth, the upper pinion 43 is coaxially fixedly connected with the lower pinion 66, a fixed sleeve 431 is rotatably sleeved between the lower pinion 66 and the upper pinion 43, and the fixed sleeve 431 is fixedly arranged on the lower surface of the grille 4; The lower pinion 66 meshes with the gear ring 65, and the gear ring 65 is disposed in the moving assembly 6. The turntable 42 drives the gear ring 65 to rotate by driving the lower pinion 66 and the upper pinion 43 to rotate, thereby driving the moving assembly 6 to turn or move horizontally.

[0023] For further information, see Figure 5-Figure 11The moving assembly 6 includes an annular shell 63, a gear ring 65 is rotatably arranged inside the annular shell 63, a circular flange is arranged on the inner ring of the annular shell 63, a fixing ring 64 is rotatably arranged on the inner side of the circular flange, and the fixing ring 64 is bolted to the lower side of the grille 4; the annular shell 63 is rotatably arranged on the lower side of the grille 4 through the fixing ring 64, so that the annular shell 63 can rotate relative to the grille 4, thereby realizing the rotation direction of the moving assembly 6.

[0024] A left driving assembly 61 and a right driving assembly 62 are symmetrically arranged at the left and right ends of the annular shell 63. A left wheel 612 is rotatably arranged on the side of the left driving assembly 61 away from the right driving assembly 62, and a right wheel 622 is rotatably arranged on the right driving assembly 62 away from the left driving assembly 61. The left driving assembly 61 drives the left wheel 612 to rotate, and the right driving assembly 62 drives the right wheel 622 to rotate. The left wheel 612 and the right wheel 622 rotate at the same speed and in the same direction, thereby driving the grille 4 to move its position, thereby realizing the suction of water at different positions of the bilge bottom, and preventing the bilge bottom water from being uncleanly sucked out.

[0025] For further information, see Figure 8 The left driving assembly 61 includes a left outer shell 611, which is welded to the outer side of the ring shell 63. A left cylindrical gear 613 is vertically rotatably arranged in the left outer shell 611. The left cylindrical gear 613 is meshedly connected to the outer side of the gear ring 65. When the gear ring 65 rotates, the gear ring 65 drives the left cylindrical gear 613 to rotate. The lower side of the left cylindrical gear 613 is coaxially fixedly connected to a bevel gear 1 614. The bevel gear 1 614 is rotatably arranged at the bottom of the left outer shell 611. The bevel gear 1 614 is meshedly connected to a bevel gear 2 615. The bevel gear 2 615 is rotatably connected to the side of the left outer shell 611, and the bevel gear 2 615 is coaxially fixedly connected to the left wheel 612 on the outer side of the left outer shell 611. The left cylindrical gear 613 is driven to rotate by the gear ring 65, and the left cylindrical gear 613 drives the bevel gear 1 614, the bevel gear 2 615 and the left wheel 612 to rotate in turn. The left wheel 612 rotates and cooperates with the right wheel 622 to rotate, thereby driving the grille 4 to move its position and sucking water from different positions on the bottom of the cabin.

[0026] For further information, see Fig. 9 and Fig.10The right driving assembly 62 includes a right housing 621, which is welded to the outer side of the ring housing 63. A bottom sleeve 623 is fixedly arranged at the bottom of the right housing 621. A right cylindrical gear 624 is rotatably connected inside the bottom sleeve 623. The right cylindrical gear 624 is meshedly connected to the outer side of the gear ring 65. The upper side of the right cylindrical gear 624 is coaxially fixedly connected to a bevel gear 3 625. The bevel gear 3 625 is meshedly connected to a bevel gear 4 626. The bevel gear 4 626 is rotatably connected to the inner side wall of the right housing 621. The bevel gear 4 626 is coaxially fixedly connected to a right wheel 622 arranged on the outer side of the right housing 621. The right cylindrical gear 624 is driven to rotate by the gear ring 65. The right cylindrical gear 624 drives the bevel gear 3 625, the bevel gear 4 626 and the right wheel 622 to rotate in turn. The right wheel 622 cooperates with the left wheel 612 to drive the grille 4 to move.

[0027] For further information, see Figure 5 and Fig.11 The front and rear ends of the lower side of the ring shell 63 are bolted to the support assembly 7, and the support assembly 7 includes a mounting seat 71. A ball 72 is rotatably set at the end of the mounting seat 71. Through the setting of the two support assemblies 7, the grille 4 can be supported to prevent the grille 4 from tilting. At the same time, the setting of the ball 72 enables the support assembly 7 to move and turn with the grille.

[0028] Working principle: place the grille 4 on the bottom of the cabin, and then start suction. As the water and air at the bottom of the grille 4 are sucked away, the pressure on the lower side of the grille 4 is reduced, and the grille 4 will be squeezed to the bottom of the cabin by the pressure on the upper side; the left wheel 612, the right wheel 622 and the two supporting components 7 on the lower side of the grille 4 can support the grille 4, so that a moving gap is maintained between the grille 4 and the bottom of the cabin, and at the same time, the grille 4 and the bottom of the cabin are kept parallel to each other. When encountering the inclined bottom surface of the bottom of the cabin, the grille 4 tilts along with the inclined bottom surface of the bottom of the cabin. At this time, the hinge component 5 can ensure that the grille 4 and the aluminum tube 2 can be adjusted at any angle, thereby facilitating the tilting movement of the grille 4.

[0029] When suction is performed, the water flow will impact the inclined surface 422 of the rotating disk 42, thereby driving the rotating disk 42 to rotate continuously, and the rotating disk 42 in turn drives the upper pinion 43 and the lower pinion 66 to rotate, and the lower pinion 66 drives the gear ring 65 to rotate continuously.

[0030] When the gear ring 65 rotates continuously, when the ring shell 63 does not rotate relative to the grille 4, the gear ring 65 will transmit power to the left drive assembly 61 and the right drive assembly 62, thereby driving the left wheel 612 and the right wheel 622 to rotate in the same direction and speed. The left wheel 612 and the right wheel 622 will drive the grille to move, thereby sucking water from different positions on the bottom of the cabin.

[0031] When the grille 4 is blocked by debris, the grille 4 no longer moves, the left wheel 612 and the right wheel 622 no longer rotate, and the left cylindrical gear 613 and the right cylindrical gear 624 no longer rotate. Since the left cylindrical gear 613 and the right cylindrical gear 624 are arranged on the ring shell 63, the gear ring 65 no longer rotates relative to the ring shell 63. The gear ring 65 and the ring shell 63 are equivalent to being arranged as one piece. At this time, the gear ring 65 will drive the ring shell 63 to rotate at the same speed, and the ring shell 63 rotates relative to the grille 4. At this time, the ring shell 63 drives the left wheel 612 and the right wheel 622 to rotate relative to the grille 4, thereby realizing the steering of the left wheel 612 and the right wheel 622, thereby realizing the change of the moving direction of the grille 4.

[0032] The annular shell 63 can automatically turn according to the obstruction of debris on the bottom of the cabin, thereby realizing the automatic obstacle avoidance function, so that it can automatically move along the direction where there are the least debris on the ground of the bottom of the cabin, that is, the direction with the least resistance. Due to the effect of gravity, water usually remains between the debris, that is, on the line with the least resistance, so that the grille 4 can move along the water distribution line, thereby sucking out the water in the bottom of the cabin, preventing the situation where a small amount of water cannot contact the grille and cannot be sucked out due to the obstruction of debris when there is little water.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
