Description

Technical Field

[0001] The present invention relates to the technical field of ships, and specifically to a bilge water suction port for a yacht. Background Art

[0002] Currently, all ships are equipped with bilge drainage devices to facilitate the extraction and drainage of water in watertight compartments. The bilge of a ship is at the bottommost part of the ship and usually accumulates engine oil stains and sundries, which can cause blockage of the drainage pipes. Especially in the case of less water volume, and due to the obstruction of sundries and oil stains, the water loses fluidity, and it is difficult for the drainage pipes to drain all the water.

[0003] Especially for the bilge structure of the workboat of a yacht, the space is narrow. Generally, the bilge water suction port device cannot be installed at the bottommost part of the compartment, resulting in the bilge water in the compartment not being completely drained. The bilge water accumulates in the compartment for a long time, which will affect the hull life in the long run, thus reducing the service life of the overall ship or causing additional maintenance costs.

[0004] Therefore, a bilge water suction port for a yacht is needed to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems, providing a bilge water suction port for a yacht.

The fixed sleeve is fixedly arranged on the lower surface of the grille;

[0011] The lower pinion gear meshes with the toothed ring, and the toothed ring is arranged inside the moving component.

[0012] Furthermore, the moving component includes an annular housing. The toothed ring is rotatably arranged inside the annular housing. A circular flange is arranged on the inner circle of the annular housing, and a fixed ring is rotatably arranged inside the circular flange. The fixed ring is bolted to the lower side of the grille.

[0035] The present invention will be specifically described below with reference to the accompanying drawings, as Figures 1-11As shown, a yacht bilge water suction port includes a grille 4 with multiple through-holes 41 evenly distributed throughout. A housing 1 is welded to the upper end of the grille 4, and a movable assembly 6 is provided at the lower end. The housing 1 is a hollow hemispherical shell, and the upper end of the housing 1 is connected to an aluminum tube 2, which has a flange 3 provided at its upper end. The grille 4 filters and blocks impurities, preventing them from entering and clogging the aluminum tube 2. If a large amount of debris is drawn into the suction port, the flange 3 can be removed to clean it. Regular inspection and cleaning of the suction port ensures proper system operation.

[0036] For further information, see Figure 2 A hinge assembly 5 is provided 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 provided in the lower cover 52. A lower slide groove 522 is provided 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 provided 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 coincide with each other. The upper hemispherical groove 511 is provided in the upper cover 51. The upper cover 51 and the lower cover 52 are fixedly connected by bolts.

[0037] A ball joint 21 is provided at the lower end of the aluminum tube 2, rotatably mounted within 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, sliding within the upper and lower grooves 512 and 522. The hinge assembly 5 allows for arbitrary adjustment of the angle between the shell 1 and the aluminum tube 2, allowing the grille 4 at the lower end of the shell 1 to adjust its angle to accommodate variations in the floor surface of the silo, maintaining the grille 4 parallel to the silo floor and facilitating water extraction when the water level is low. The slide bar 22 slides within the upper and lower grooves 512 and 522, securing the aluminum tube 2 and the hinge assembly 5 relative to each other circumferentially, preventing the hinge assembly 5 from rotating about the axis of the aluminum tube 2.

[0038] For further information, see Figures 3-5 The center of the upper side of the grille 4 is rotatably connected to a turntable 42, which is coaxially fixedly connected to a scraper 44, located on the lower side of the grille 4. A plurality of spokes 421 are evenly distributed axially on the turntable 42, and a sloped surface 422 is provided on the lower side of the spokes 421. During operation, when water flows through the grille 4, the water impacts the sloped surface 422, pushing the turntable 42 to rotate. The turntable 42 drives the scraper 44 to rotate, scraping the lower surface of the grille 4 to prevent the through-holes of the grille 4 from being clogged by debris.

[0039] For further information, see Figures 3-7 , gear teeth are provided on the outer periphery of the turntable 42, the turntable 42 is meshed with the upper pinion 43 through the gear teeth, the upper pinion 43 is coaxially fixedly connected to the lower pinion 66, and a fixed sleeve 431 is rotatably sleeved between the lower pinion 66 and the upper pinion 43, and the fixed sleeve 431 is fixedly provided on the lower surface of the grille 4;

[0040] The lower pinion gear 66 meshes with the gear ring 65, and the gear ring 65 is arranged inside the moving component 6. The turntable 42 drives the lower pinion gear 66 and the upper pinion gear 43 to rotate, thereby driving the gear ring 65 to rotate, and then driving the moving component 6 to turn or move horizontally.

[0041] Further, referring to Figures 5-11 , the moving component 6 includes an annular shell 63. The 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, and a fixed ring 64 is rotatably arranged on the inner side of the circular flange. The fixed ring 64 is bolted to the lower side of the grille 4; by rotatably arranging the annular shell 63 on the lower side of the grille 4 through the fixed ring 64, the annular shell 63 rotates relative to the grille 4, realizing the rotational direction of the moving component 6.

[0042] The left driving component 61 and the right driving component 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 component 61 away from the right driving component 62, and a right wheel 622 is rotatably arranged on the side of the right driving component 62 away from the left driving component 61. By driving the left wheel 612 to rotate through the left driving component 61 and driving the right wheel 622 to rotate through the right driving component, 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, realizing the suction of water at different positions at the bottom of the bin and preventing the situation that the bilge water cannot be sucked clean.

[0043] Further, referring to Figure 8 , the left driving component 61 includes a left outer shell 611. The left outer shell 611 is welded to the outer side of the annular shell 63. A left cylindrical gear 613 is vertically rotatably arranged inside the left outer shell 611. The left cylindrical gear 613 is meshed and connected to the outer side of the gear ring 65. When the gear ring 65 rotates, the gear ring 65 will drive the left cylindrical gear 613 to rotate. A first bevel gear 614 is coaxially fixed to the lower side of the left cylindrical gear 613. The first bevel gear 614 is rotatably arranged at the bottom of the left outer shell 611. The first bevel gear 614 is meshed and connected to a second bevel gear 615. The second bevel gear 615 is rotatably connected to the side of the left outer shell 611, and the second bevel gear 615 is coaxially fixed to the left wheel 612 on the outer side of the left outer shell 611. By driving the left cylindrical gear 613 to rotate through the gear ring 65, the left cylindrical gear 613 drives the first bevel gear 614, the second bevel gear 615 and the left wheel 612 to rotate in sequence. The left wheel 612 rotates, and cooperates with the rotation of the right wheel 622, thereby driving the grille 4 to move its position and sucking the water at different positions at the bottom of the bin.

[0044] Further, referring to Figure 9 and Figure 10, the right drive assembly 62 includes a right housing 621 welded to the outer side of the ring housing 63. A bottom sleeve 623 is fixedly provided 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 meshed and connected to the outer side of the toothed ring 65. A third bevel gear 625 is coaxially and fixedly connected to the upper side of the right cylindrical gear 624. The third bevel gear 625 is meshed and connected to a fourth bevel gear 626. The fourth bevel gear 626 is rotatably connected to the inner side wall of the right housing 621. The fourth bevel gear 626 is coaxially and fixedly connected to a right wheel 622 arranged on the outer side of the right housing 621. The toothed ring 65 drives the right cylindrical gear 624 to rotate. The right cylindrical gear 624 drives the third bevel gear 625, the fourth bevel gear 626 and the right wheel 622 to rotate in sequence. The right wheel 622 cooperates with the left wheel 612 to drive the grille 4 to move its position.

[0045] Further, referring to Figure 5 and Figure 11 , both the front and rear ends of the lower side of the ring housing 63 are bolted with support assemblies 7. The support assembly 7 includes a mounting seat 71. A rolling ball 72 is rotatably arranged at the end of the mounting seat 71. Through the arrangement of the two support assemblies 7, the grille 4 can be supported to prevent the grille 4 from tilting. At the same time, the arrangement of the rolling ball 72 enables the support assembly 7 to follow the grille to move its position and turn.

[0046] Working principle: Place the grille 4 at the bottom of the cabin, and then start suction. Since the water and air at the bottom of the grille 4 are pumped away, the pressure below the grille 4 decreases, and the grille  4 will be squeezed against the bottom of the cabin by the pressure above; the left wheel 612, the right wheel 622 and the two support assemblies 7 below 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 cabin bottom, the grille 4 tilts along with the inclined bottom surface of the cabin bottom. At this time, the hinge assembly 5 can ensure any angle adjustment between the grille 4 and the aluminum pipe 2, so as to facilitate the inclined movement of the grille 4.

[0047] During suction, the water flow will impact the inclined surface 422 of the turntable 42, thereby driving the turntable 42 to rotate continuously. The turntable 42 drives the upper pinion 43 and the lower pinion 66 to rotate in sequence. The lower pinion 66 drives the toothed ring 65 to rotate continuously.

[0048] When the toothed ring 65 rotates continuously, when the ring housing 63 does not rotate relative to the grille 4, at this time, the toothed ring 65 will transmit the 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 at the same speed. The left wheel 612 and the right wheel 622 will drive the grille to move its position, so as to suck the water at different positions of the cabin bottom.

[0049] When the grille 4 is blocked by sundries, 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 housing 63, the toothed ring 65 no longer rotates relative to the ring housing 63 at this time. The toothed ring 65 and the ring housing 63 are equivalent to being integrally arranged. At this time, the toothed ring 65 will drive the ring housing 63 to rotate at the same speed. The ring housing 63 rotates relative to the grille 4. At this time, the ring housing 63 drives the left wheel 612 and the right wheel 622 to rotate relative to the grille 4, so as to realize the steering of the left wheel 612 and the right wheel 622, and thus realize the change of the moving direction of the grille 4.

[0050] The ring housing 63 can automatically turn according to the blocking situation of sundries at the bottom of the cabin, so as to realize the automatic obstacle avoidance function, and can automatically move along the direction with the least sundries on the bottom surface of the cabin, that is, the direction with the least resistance. Due to the action of gravity, water usually remains between the sundries, that is, on the line with the least resistance. Thus, the grille 4 can move along the line where the water is distributed, so as to suck the water at the bottom of the cabin clean, preventing the situation that in the case of less water, due to the blocking of sundries, a small amount of water cannot contact the grille and cannot be sucked clean.
