However, the ship consumes a large amount of fuel in the process of sailing, and NO generated by burning the fuelx、SOxAnd CO2Gas and PM2.5 pollutants further increase the burden on the environment. Therefore, how to reduce the ship tail gas pollution is an important problem to be solved urgently today.
Wind energy is favored as a clean, pollution-free renewable energy source for ships. The ship sails on the sea, the sea level is open, and the offshore wind energy resources are abundant, so that the ship has great advantage of boosting by using wind energy. The application of wind energy on the ship is beneficial to reducing the consumption of fossil fuel by the ship, thereby reducing the environmental pollution and realizing the energy conservation and emission reduction of the ship.
Based on this, chinese patent No. CN 106938693B discloses a circular truncated cone-shaped sail device using magnus effect, chinese patent No. CN 112849381 a discloses a sail device and ocean cargo vessel, and chinese patent No. CN 112124547 a discloses an airfoil-shaped sail, which can provide good propulsion for ships, and thus, the application of wind energy to ships is realized. However, the sails of the above patent occupy a large amount of deck space, and are difficult to be applied to small and medium-sized ocean vessels such as some grocery ships, small flexible bulk freighters and the like because: the small and medium-sized ocean vessels have small size and limited deck space, and when a vessel cargo handling machine or similar equipment is installed, the remaining deck space is not enough for installing sails with larger size, such as a rotary tube sail, an airfoil sail and the like. In addition, the wing-shaped sail needs to be continuously adjusted in the windward state according to the ship course and the wind direction so as to generate forward propelling force for the ship, a special sail revolving system needs to be arranged, and a mast needs to be arranged for hanging the sail, so that the structure of the sail boosting device becomes complicated, and the cost investment of the device is increased.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and examples.
A wind-assisted vessel loader, as shown in figures 1, 2 and 3, the device comprising: the device comprises a winding drum 1, a rotating shaft 2, a sail 3, an L-shaped support rod 4, a pulley 5, a traction rope 6 and a rotation system 7.
The invention reasonably utilizes the original ship cargo plane of the small and medium-sized ocean-going ship to realize the fusion of the sail 3 and the ship cargo plane, and as shown in figure 1, the sea wind is utilized to provide extra propulsive force for the sailing ship. Because the ship cargo aircraft is provided with the rotation system and has higher height, a new rotation mechanism and a mast are not needed to be additionally arranged for the sail 3, and the cost of the device is reduced. The device is arranged on two ship cargo cranes, when in use, the two cargo cranes rotate towards the port and the starboard respectively, and the wind sails 3 are unfolded at the port and the starboard respectively, so that the effective recovery area of the device for wind energy can be increased, and the stability of a sailing ship is ensured.
As shown in figures 2 and 3, one side boom rod of the ship cargo lifter boom is replaced by a winding drum 1, the winding drum 1 and a transverse reinforcing rod of the boom are rigidly fixed and can not rotate, and the winding drum 1 has a certain thickness so as to ensure the structural strength of the ship cargo lifter during cargo loading and unloading. The shaft 2 is provided in the reel 1, and as shown in fig. 3, the shaft 2 is rotatable within the reel 1. The sail 3 is in a rolling curtain type design, is connected with the rotating shaft 2 in the winding drum, and is folded and unfolded through the rotation of the rotating shaft 2. The sail 3 is in a triangular shape, and does not deform obviously under the action of wind force when in use, so that the conversion of wind energy to mechanical energy of the ship is realized to the maximum extent, and the propulsive force is improved. L type bracing piece 4 locates the top of the lifting column of boats and ships cargo aircraft, upwards extends by the lifting column and forms certain height, is equipped with a pulley 5 on the 4 topmost horizon bars of L type bracing piece. The haulage rope 6 is the device that is used for pulling sail 3, and haulage rope 6 one end is connected with sail 3, and the other end is located in reel 1, and the rise of sail 3 is realized by the pulling force effect of haulage rope 6. The top end of the traction rope 6 is matched with the pulley 5, and the direction of force on the traction rope 6 is changed under the action of the pulley 5. The turning system 7 is combined with the original turning system of the ship cargo plane and used for adjusting the turning direction of the sail to adapt to the change of the wind direction. As shown in fig. 4, when the sail 3 is furled, the sail is furled in the reel 1 under the rotation of the rotating shaft 1.
The relationship between the ship heading and the wind direction is shown in FIG. 5: and when the angle formed by the rotation from the ship sailing direction to the wind direction along the anticlockwise direction is theta, the ship is judged to have wind coming from the stern direction when the theta is in the range of 0 degrees, 60 degrees, U [300 degrees and 360 degrees ], and the ship sails downwind. At the moment, the device can generate larger forward propelling force by utilizing the wind direction in the area, and the using effect of the device is good.
When the stern direction is windy, namely theta is equal to [0 ], 60 DEG ] and U [300 DEG, 360 DEG ], the ship cargo plane rotates towards the port and the starboard of the ship respectively, and simultaneously the sail 3 rises under the action of the tension of the hauling rope 6, as shown in figure 6. Because the wind direction can change relative to the ship when the ship sails, the windward state of the sail 3 can be adjusted by utilizing the rotation of the ship cargo aircraft rotating system 7, and the effective utilization of wind energy is improved.
As shown in fig. 7, when the stern direction of the ship is windy and the wind direction forms a certain angle with the ship sailing, the sail 3 is always perpendicular to the wind direction under the rotation of the cargo-handling machine rotating system 7, and at this time, the sail 3 will generate an additional propelling force component F along the sailing direction1And a side force component F in the width direction of the ship2And the boosting of the sail is realized.
As shown in fig. 8, when wind comes in a direction other than the stern direction, the sail 3 is retracted into the drum 1 by the rotation of the rotating shaft 2, the ship loader is returned to the original position, and the device does not generate an extra wind receiving area, so that extra sailing resistance is not generated when the ship sails. As shown in fig. 9, when the ship passes through the bridge water area, the L-shaped support rods 4 can be retracted to ensure that the ship can pass through safely.
The device is applied to ships with limited deck space, such as a grocery ship, a small flexible bulk cargo ship, a multipurpose ship and the like, which are provided with the ship cargo lift, the integration of the sail and the ship cargo lift is realized, the problem of mounting the sail on small and medium-sized ocean ships with limited deck space resources is solved, and the device has strong practical significance. The embodiment only introduces the working principles of the two ship cargo lifts designed by the invention, and more ship cargo lifts can be arranged along the ship length direction of the ship under the condition that the normal work of the ship cargo lifts is not influenced actually, and the ship cargo lifts can provide additional propelling force for the ship, so that the boosting effect is improved.
The above description is only a preferred embodiment of the present invention, but is not limited by the above embodiments, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
