technical field

The invention relates to the technical field of sails, in particular to a grid type sail that can intelligently control the tightening direction.

Background technique

The sail is the earliest power tool used on ships in history. With the advancement of science, sails are being replaced by some better performance internal combustion engines and other power devices, but due to the outbreak of the oil crisis and the rise in oil prices, the use of sails as auxiliary power to assist ships has become a hot issue. For sails, due to other influencing factors such as height limit, weight limit and wind resistance, traditional sails have little room for adjustment in these aspects, especially wind resistance, which cannot be controlled, so traditional sails often fail to achieve the desired effect.

The advantage of the boat's endurance. Announcement No. CN109649619A "Well Girder Sail Surface Frame Structure", the sail surface includes a middle sail surface located in the middle, the second end and the third end connected above and below the middle sail surface, connected to the middle sail surface The fourth end and the fifth end on the left and right sides of the sail surface; a plurality of first lateral support structures and a plurality of first vertical support structures are arranged inside the middle sail surface. Strength requirements under combined action of gravity and inertial loads with optimized weight.

The existing technology mainly controls the sail on one side, that is, the sail only bulges to one side during the sailing process of the ship, and the angle and force of the sail are controlled by changing the skeleton structure or the shape of the sail surface on one side of the sail. Purpose. However, when the wind direction changes suddenly, if the bulge direction of the sail is not changed in time, it will have an adverse effect on the navigation of the ship.

As shown in FIG. 1 and FIG. 2 , this embodiment discloses a grid-type sail that can intelligently control the tightening direction, including a side frame, a sail body, a flexible strut, a control valve, a sensor and a rotating shaft. The body 2 is connected to the inner side of the side frame 1, and the two sides of the side frame are provided with several flexible struts 3 symmetrically arranged, the flexible struts and the edge frame form a diamond-shaped grille, and the center of the sail body is provided with The control valve 4 is provided with several rotating shafts 6 that are connected to it symmetrically, the end of the strut is connected to the side and its corresponding rotating shaft, and a number of wind pressure sensors 5 are arranged at different positions on the surface of the sail, and each wind pressure sensor is real-time. A signal is passed to the control valve. The selected wind pressure sensor can transmit the external signal to the control valve according to the basic sensing function, thereby realizing intelligent control. Specifically, when the wind direction and the running direction of the ship are in the same direction, the sail is regulated to tighten the sail in the opposite direction, so as to ensure that the angle of the wind blowing the sail is consistent with the running direction of the ship. If the wind is in the opposite direction of the boat, keep the sails taut in the opposite direction of the boat to ensure the wind does not blow the sails. When the angle of the wind forms a certain angle with the ship, the angle of tightening and opening of the sail is regulated according to the wind direction and the direction of the ship. The support rod selected in this embodiment has a good degree of flexibility and is not easily broken when bent.

As shown in FIG. 3 , the longitudinal section of the control valve in this embodiment is circular, and the side frame is rhombus. For structural stability and easy control of the sail angle, there are 8 flexible struts on one side, which are respectively connected to The vertices of the rhombus, the midpoints of each side, and the rotating shafts are evenly distributed on the circumference of the control valve.

The flexible strut is closely connected with the sail surface through the fixing ring, and plays the role of supporting the side frame and controlling the deformation angle of the sail.

In order to ensure that the internal force of the strut does not exceed its allowable strength range, as a preferred embodiment, a force sensor 7 for measuring the connecting force is provided at the connection between the flexible strut and the edge frame. Once the connecting force is too large, the locking stops. Through the above method, the deployment angle of the sail can be realized. Since the above processes can realize self-perception control, intelligent autonomous control of sails can be realized according to the set parameters, which can be used on unmanned ships.
