Description

Technical Field

[0001] The utility model relates to the technical field of floating cleaning boats, in particular to an auxiliary device for cleaning objects entangled in a propeller of a floating cleaning boat. Background Art

[0002] At present, most floating cleaning boats use propeller propulsion, which is favored by surface floating cleaning operators because of its flexible steering and high propulsion efficiency. However, the propeller has a major disadvantage, that is, while the propeller rotates for propulsion, its high-speed rotation causes some linear water plants and floating objects to be entangled on the rotating shaft. When the entanglement reaches a certain amount, the propeller speed will be reduced. In severe cases, the entanglement may even cause the propeller to be unable to rotate. At this time, the operator needs to go into the water to clean up. The difficulty of cleaning is affected by factors such as the depth of the operating water area and whether it is silted, which brings great difficulties to the cleaning work. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, the utility model provides a technical solution: an auxiliary device for cleaning entanglements on a propeller of a floating cleaning boat, comprising a hanger 1 hung on the side of the boat, a ladder frame 2 vertically fixedly connected to the bottom of the hanger 1, and a support frame 3 horizontally fixedly connected to the bottom of the ladder frame 2. The hanger 1, the ladder frame 2 and the support frame 3 are all welded steel pipe structures, which are easy to manufacture;

[0027] The pylon 1 comprises two U-shaped frames 101 suspended on the ship's side, a connecting longitudinal rod 102 fixedly connected longitudinally to the inside of the U-shaped frames 101, and a connecting crossbar 103 fixedly connected transversely between the two U-shaped frames 101 and the two connecting longitudinal rods 102. The ladder frame 2 is fixedly connected to the middle of the connecting longitudinal rod 102 near the front end.

[0028] One side of the ladder frame 2 is horizontally fixedly connected to a positioning rod 4, and the other side of the ladder frame 2 is movably connected to a guardrail 6 at a corresponding position through a universal joint 5. The guardrail 6 is U-shaped, and a protective soft cover 9 is sleeved on the surface of the guardrail 6. The universal joint 5 includes a horizontal collar 501 rotatably connected to the surface of the vertical rod of the ladder frame 2. The outside of the horizontal collar 501 is horizontally fixedly connected to a connecting shaft 502, and the surface of the connecting shaft 502 is rotatably connected to a vertical collar 503. One end of the guardrail 6 is fixedly connected to the vertical collar 503;

[0029] The end of the guardrail 6 is fixedly connected to a spring lock 7, which is movably sleeved on the surface of the positioning rod 4. The spring lock 7 includes a U-shaped buckle 701 fixedly connected to the end of the guardrail 6, the U-shaped buckle 701 opening facing the positioning rod 4 and sleeved on the surface of the positioning rod 4. The upper end of the U-shaped buckle 701 is movably hinged to a locking rod 704 in a slot 703 provided in the lower end through a torsion spring shaft 702.

[0030] A protective net 8 is fixedly connected to the upper surface of the support frame 3, and the lower end of the ladder frame 2 is fixedly connected to the upper surface of the support frame 3 near the rear end. The surfaces of the hanger 1, ladder frame 2 and support frame 3 are all covered with protective covers 10 at positions corresponding to the ship's side, and diagonal braces 11 are provided between the front and back sides of the lower end of the ladder frame 2 and the support frame 3.

[0031] Working principle:

[0032] By pushing the upper end of the locking rod 704 to avoid blocking the positioning rod 4, the spring lock buckle 7 can be removed from the positioning rod 4, the protective railing 6 can be flipped open around the universal joint 5, the propeller can be flipped upward to move it out of the water, and the hanger 1 can be hung on the side of the ship near the propeller. The operator goes down to the support frame 3 through the ladder frame 2, stands, squats or sits on the support frame 3, flips the protective railing 6 around the universal joint 5 to close the protective railing 6, and the positioning rod 4 squeezes the locking rod 704 to rotate around the torsion spring shaft 702 to make way. After the U-shaped buckle 701 is stuck to the outside of the positioning rod 4, the torsion spring shaft 702 drives the locking rod 704 to reset and get stuck in the slot 703, so that the spring lock buckle 7 is stuck on the positioning rod 4. The operator can free his hands through the protection of the protective railing 6, and the operator can clean the propeller without going into the water, which greatly facilitates the cleaning work.
