DETAILED DESCRIPTION

[0021] The content of the utility model will be further described in detail in combination with specific examples:

[0022] For example, Figure 1 And Figure 2As shown, the cleaning vessel includes a hull 11, with a tipping bucket 12 at the front end of the hull 11. The tipping bucket 12 is rotatably connected to the hull 11 via a tipping device 13 and is used for cleaning waterways. A drive unit is provided at the stern end of the hull 11, which includes a propeller 2 for driving the hull 11 and a steering assembly 3.

[0023] The steering assembly 3 includes a rudder mechanism 31 and a rudder drive mechanism 32. For example... Figure 3 As shown, the servo drive mechanism 32 includes a steering seat 321 and a pair of hydraulic actuators 322. The steering seat 321 is a horizontal quadrilateral structure, and its middle part is coaxially fixed with the servo mechanism 31, while its two ends are respectively hinged to a pair of hydraulic actuators 322. The end of any hydraulic actuator 322 away from the steering seat 321 is hinged to a fixed frame 323 mounted on the deck, so that the pair of hydraulic actuators 322 can drive the steering seat 321 to swing the servo mechanism 31 by alternating actions.

[0024] In this embodiment, in order to save deck area, the fixing frame 323 is located on the right side of the steering seat 321, so that a pair of hydraulic actuators 322 are arranged in a direction perpendicular to the length of the hull 11.

[0025] like Figure 4 As shown, the rudder mechanism 31 includes a rudder shaft 311 arranged vertically, with a rudder blade 312 fixed on the rudder shaft 311, and the plane of the rudder blade 312 being parallel to the axis of the rudder shaft 311. A bearing is fitted at the top of the rudder shaft 311 and extends through the hull 11. The steering seat 321 is rotatably mounted on the top of the rudder shaft 311. This allows the rotation of the steering seat 321 to drive the rudder shaft 311 to swing the rudder blade 312, thereby controlling the ship's steering.

[0026] In this embodiment, the projection of the rudder blade 312 on the horizontal plane is streamlined, which reduces the ship's sailing resistance. A bracket 313 is also fixed to the bottom of the stern of the hull 11, and the bottom of the rudder shaft 311 is rotatably connected to the bracket 313 to enhance the strength of the rudder shaft 311 and prevent the rudder shaft 311 from deforming.

[0027] A clearing hole 4 is provided at the stern of the hull 11. The clearing hole 4 extends vertically through the hull 11, with its top end connecting to the deck and its bottom end corresponding to the propeller 2, allowing the crew on deck to clear obstacles entangled in the propeller 2 through the clearing hole 4. Furthermore, on the deck at the stern of the hull 11, mooring equipment 5 is symmetrically arranged relative to the rudder shaft 311. Specifically, the mooring equipment 5 includes mooring bollards and mooring lines wound around them.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
