Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
As shown in fig. 1 and 2, an energy saving breakwater with adjustable angle comprises a lower wall plate 20 fixed on a deck 10, and an upper wall plate 30 hinged to an upper end of the lower wall plate 20. The upper and lower panels are connected by a hinge 15.
The front end face of the lower wall plate is an end face facing the bow, and the rear end face of the lower wall plate is an end face facing the stern.
The front end surface of the upper wall plate 30 and the front end surface of the lower wall plate 20 are both flat surfaces. The lower wall panel 20 is perpendicular to the deck 10.
The rear end face of the lower wall plate 20 is fixedly provided with a first reinforcing beam 21, and the first reinforcing beam 21 is connected with the lower wall plate 20 in a welding manner. The second reinforcing beam 22 is fixedly arranged on the rear end surface of the upper wall plate 30. The second stiffening webs 22 are welded to the upper panel 30.
The upper end of the first reinforcing truss 21 is distributed obliquely downward from the upper end of the upper panel; the angle between the upper end of the first stiffening web 21 and the lower wall panel 20 is acute.
The lower end portions of the second reinforcing girders 22 are distributed obliquely upward from the lower end portion of the upper wall panel; the angle between the lower end of the second stiffening web 22 and the upper panel 30 is acute.
The energy-saving breakwater with adjustable angle further comprises a telescopic mechanism which can enable the upper wall plate to rotate around the top of the lower wall plate, and in the embodiment, the telescopic mechanism is a hydraulic oil cylinder 40. The two ends of the telescopic mechanism are hinged to the rear end face of the lower panel 20 and the second reinforcing beam 22, respectively.
The rear end face of the lower wall plate 20 is fixedly provided with a first ear plate 11; the second reinforcing truss 22 is fixedly connected with a second lug plate 12, and the bottom of the hydraulic oil cylinder 40 is hinged to the first lug plate; the piston of the hydraulic cylinder 40 is hinged to the second ear plate 12.
The rear end face of the upper wall plate 30 and the rear end face of the lower wall plate 20 are fixedly provided with transverse reinforcing ribs 31.
The top of the upper wall plate 30 is fixedly provided with a top plate 32 which is transversely distributed. The top plate 32 extends from the upper end of the upper wall plate to the rear of the upper wall plate. The upper end of the second reinforcing beam 22 is fixed to the top plate 32.
The breakwater is arranged on a first floor deck of a ship, and the upper wall plate and the lower wall plate can be positioned on the same plane under the action of the hydraulic oil cylinder, as shown in figure 2. The upper panel may also be inclined towards the stern under the influence of hydraulic rams, as shown in figure 3. The inclination angle of the upper wall plate can be adjusted according to the marine environment and the navigational speed.
When the wave on the bow is larger due to severe sea conditions and the wave on the bow is larger, the upper wall plate is propped by the hydraulic oil cylinder, the upper wall plate is not inclined, and the upper wall plate and the lower wall plate are positioned on the same plane, so that the waves can be blocked within the total height range of the lower wall plate and the upper wall plate, and equipment or goods behind the wave blocking plate can be protected within the maximum range.
When the upper wall plate inclines towards the stern, the air resistance of the breakwater is obviously reduced, and the principle is as follows:
calculation formula of air resistance Fw is 1/16 × a × Cw × V2Where Fw is the air resistance, Cw is the wind resistance coefficient, A is the wind area, and V is the velocity. When the upper wall plate inclines towards the stern direction, A (wind receiving area) is obviously reduced, and the upper wall plate plays a role of a wind deflector, so that Cw (wind resistance coefficient) is obviously reduced. The air resistance is obviously reduced at the moment according to the calculation formula of the air resistance.
When the bow is small in upwave, the lower wall plate can block the wave, and at the moment, the upper wall plate is inclined towards the stern direction through the hydraulic oil cylinder. At the moment, the lower wall plate plays a role in wave blocking, and the upper wall plate plays a role in an air deflector. The wind area of the whole wave blocking plate is reduced, the appearance of the wave blocking plate is closer to the streamline, when the wave blocking plate passes through air, the air can better flow to the tail part, the air flow separation is reduced, the vacuum area is reduced, the pressure difference resistance is reduced, and the energy consumption of a ship is saved.
The breakwater of the invention has the following advantages:
1. the upper wall plate can incline towards the stern, so that the wind area of the front surface of the wave board can be reduced, and the air resistance is reduced.
2. The inclination angle of the upper wall plate can be adjusted according to the wave-up condition of the bow of the ship, so that the wave-blocking and resistance-reducing functions are exerted to the maximum.
3. After the upper wall plate is inclined towards the stern, the shape of the breakwater is close to streamline, and when the breakwater passes through air, the air can better flow to the tail part, so that the air flow separation is reduced, the vacuum area is reduced, the pressure difference resistance is reduced, and the energy consumption of the ship is saved.
The invention can play a role of wave blocking and can guide airflow to pass through the wave blocking plate more smoothly according to different marine environments and navigation speeds, thereby obtaining higher aerodynamic performance, reducing driving resistance and saving energy consumption.
