Problems solved by technology

[0002] During the sailing process of the ship, the wind direction and course are constantly changing, and the sail angle needs to be adjusted in time to maximize the propulsion power of the sail; moreover, when a ship with sails encounters a lower bridge, the height of the sail surface needs to be lowered. When it is large, it is necessary to furl the sails in order to avoid excessive lateral forces affecting the stability of the ship. When docking at the port, the sails must be furled to maintain stability, etc. All these factors require the sails to have a flexible attitude angle control device. The structure of the adjustment device is relatively complicated, and the adjustment of the sail rotation angle is not convenient enough

Embodiment 1

[0051] Since the sail 1 is affected by the light and the wind direction at the same time when the ship is sailing, the device for adjusting the angle of the sail in the present invention can mainly realize the conversion of the sail 1 at any angle in three-dimensional space, so that the ship can obtain the maximum propulsion However, during the voyage of the ship, the angle of sunlight and the direction of the wind are constantly changing, so the sail needs to be rotated continuously so that the rotation and tilt angle of the sail 1 can be obtained in a timely and accurate manner. Adjustment, which requires precise calculation of the best rotation and tilt angle of the sail, and effective control of the hydraulic rod 4 and the slewing mechanism 3 through the controller, so as to achieve the adjustment of the desired sail angle in the actual situation effect in order to obtain the best comprehensive utilization of energy.

[0052] Therefore, it is necessary to accurately calcul...

Embodiment 2

[0092] In this embodiment, a set of specific parameters for applying the device for adjusting the angle of the sail to each component in practice is given, and the structure and adjustment method of the device for adjusting the angle of the sail in this embodiment are the same as those in the embodiment All are consistent, but it should be noted that the parameters in this embodiment are not unique, and in other embodiments, appropriate parameters can be selected.

Abstract

The invention provides a device for adjusting a sail angle. The device for adjusting the sail angle comprises a sail, a first base, a swing mechanism and a hydraulic rod, the sail is connected to the first base, the two ends of the hydraulic rod are respectively connected with the sail and the first base, the swing mechanism comprises a first gear device, a drive shaft and a second gear device, the first base is connected with the first gear device, and the first gear device and the second gear device are connected through the drive shaft. The device for adjusting the sail angle is simple in structure, can make the sail angle of a ship change more flexibly, so that the propulsion power of the sail to the ship is improved. A method for adjusting the sailing angle comprises the steps that the second gear device transmits power to the first gear device through the drive shaft, and the first gear device drives the first base to rotate, so that the sail achieves rotation of 360 degrees in the vertical direction. The sailing is driven by the hydraulic rod to complete tilt of 0-90 degrees, the method can complete adjusting of the sail angle of the ship, and the process is simple.

Description

technical field [0001] The invention relates to a device and an adjusting method for adjusting the angle of a sail. Background technique [0002] During the sailing process of the ship, the wind direction and course are constantly changing, and the sail angle needs to be adjusted in time to maximize the propulsion power of the sail; moreover, when a ship with sails encounters a lower bridge, the height of the sail surface needs to be lowered. When it is large, it is necessary to furl the sails in order to avoid excessive lateral forces affecting the stability of the ship. When docking at the port, the sails must be furled to maintain stability, etc. All these factors require the sails to have a flexible attitude angle control device. The device structure of adjustment is comparatively complicated, and the adjustment of sail rotation angle is not convenient enough. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of th...
