Description
Technical Field
The invention belongs to the technical field of ships, and particularly relates to a self-adaptive combination device for large-scale commercial ship sails and multi-turbine power generation.
Background
With the general improvement of the pollution problem of ships in the international range, the energy conservation and emission reduction of the ships become one of the hot spots of the current shipping industry research. The conventional large commercial ship needs to burn fuel oil for power supply during sailing, and NO generated by burning the fuel oilx、SOxAnd CO2Gas and PM2.5 pollutants further increase the burden on the environment. Currently, the use of wind energy on ships is favored, not only because wind energy is a clean and pollution-free renewable energy source, but also because most of the marine sea levels of large commercial ships are open, the wind energy resources are very abundant. The application of the wind energy on the ship can reduce the use of fossil fuel, relieve the energy crisis, reduce the environmental pollution and realize the energy conservation and emission reduction of the ship.
Based on this, chinese patent No. CN 212386673U discloses a bulk cargo ship boosted by wind energy, which realizes wind energy boosting, but the wind capturing device is fixed in orientation, and when the wind direction changes and forms an included angle with the device, the utilization rate of the device to wind energy is very low; and when the ship sails against the wind, the wind power capture device can generate certain resistance, and thrust generated by wind power is not enough to make up for extra resistance generated by the installation device, so that the ship is not paid. Chinese patent No. CN 201296368Y discloses a wind power generation system, which uses a single generator to capture wind energy for power generation, and compared with a plurality of wind power generators (wind turbines), the system has the advantages of small effective recovery area of wind energy, low utilization rate of wind energy, and poor power generation effect. Chinese patent No. CN 106536923 a discloses a multi-turbine wind power generation platform for offshore application, which recovers wind energy by using multiple turbines, but this method can only be installed at fixed points, and cannot be applied to a sailing ship to generate energy to reduce the emission of the ship. Chinese patent No. CN 109667720 a discloses a device for switching between marine wind power boosting and wind power generation, which performs wind power boosting when a ship sails, and generates power by using wind power when the ship stops sailing, thereby greatly improving the utilization rate of wind power. However, the device can only use the wind energy boosting mode alone when sailing, and cannot generate electricity, and the device inevitably generates resistance when sailing against the wind, so that extra fuel consumption is generated.
The sail is used as an ancient ship power device and has important application in various small and medium-sized ships so far. The maximum power source of the sailing boat is the Bernoulli effect, and when the boat sails in the downwind, the pressure generated by the impact of the wind on the sail is mainly used for pushing the boat to advance; when the ship is in a side-to-side wind, due to the arc design of the wind sail, when the airflow passes through the sail, the airflow in front of the sail needs to take a longer distance to be converged with the airflow behind the sail, so that the airflow in front of and behind the sail can generate different flow rates, the flow rate of the airflow in front of the sail is higher, according to Bernoulli' principle, the flow rate of the air is higher, the pressure is lower, the pressure behind the sail is stronger than the pressure in front of the sail, and the pressure difference can generate forward thrust on the ship; when sailing against the wind, the ship course and the wind direction form a certain included angle, and the ship sails along a zigzag route, so that the problem that the sail cannot utilize the against wind is solved. The large-scale merchant ship can realize the common propulsion of fuel and sail, and the sail can provide partial propulsive force for the boats and ships, saves the consumption of fuel. However, when sailing against the wind, the large-scale merchant ship cannot adopt the zigzag sailing to realize the sail boosting, because: the large merchant ship has a large direct contact area with seawater due to large size and total load capacity, so that seawater generates very large resistance on a ship body, the relatively small thrust of the propulsion of the sail can only be used as auxiliary propulsive force of the ship and cannot be used as a main propulsive force source of the large ship, if the large merchant ship sails along a zigzag path, although the sail can be used for boosting, the length of a flight line of the ship is greatly increased, fuel consumption is increased, and the fuel consumption which can be saved by using the propulsion of the sail is far less than the extra fuel consumption of the ship due to the increase of the course, so that the extra fuel consumption is not paid. Therefore, although sail boosting can bring great benefits when a large commercial ship sails downwind, sail boosting is not feasible too much when the large commercial ship sails upwind.
Based on the above, if the wind energy utilization device can be provided in a large commercial ship, the device can not only fully recover a large amount of wind energy around the sailing ship and self-adaptively adjust the windward state according to the wind direction, but also overcome the phenomenon that the wind energy utilization device is not paid back because of extra sailing resistance generated by being installed on the ship when the ship sails against the wind, and the wind energy utilization device has better practical application significance for the large commercial ship to utilize the wind energy.

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.
An adaptive combination device of a large-scale merchant sail and multi-turbine power generation, as shown in fig. 1, 2, 3, 4, 5 and 6, the device comprises: the wind power generation device comprises a base 1, a base top cover 2, a hydraulic motor 3, a sail rotating shaft 4, a sail bottom plate 5, a sail support 6, a sail 7, a fan support 8, a wind turbine 9, a wind direction sensor 10, an upper hinged support 11, a lower hinged support 12, a hydraulic oil cylinder 13, a buckle 14 and a clamping seat 15.
As shown in fig. 1 and 2, the device of the invention fixes the base 1 on the deck at the bow position, and one end of the base top cover 2 is connected with the base 1 through a rotating shaft, so that the base top cover 2 can be turned around the rotating shaft at one side. The hydraulic motor 3 is installed inside the base 1 and is a power source capable of rotating, a transmission shaft of the hydraulic motor 3 is coaxially matched with a sail rotating shaft 4 on the base top cover 2, and the sail rotating shaft 4 can rotate by means of transmission of the hydraulic motor 3. The sail bottom plate 5 is rigidly fixed on the sail rotating shaft 4 and can rotate together with the sail rotating shaft 4. The sail support 6 and the fan support 8 are fixed on the sail bottom plate 5, the sail 7 is lifted or retracted by utilizing the guiding effect of the vertical rods of the sail support 6, the sail 7 is fixed by the sail support 6 when lifted, the sail 7 forms a cambered surface, and the sail 7 is placed on the sail bottom plate 5 when retracted. The power generation part consists of dozens of wind turbines 9 and is uniformly fixed on the fan bracket 8 according to a certain distance. The wind direction sensor 10 is installed on the top of the sail support 6 and used for detecting the wind direction. Two hydraulic oil cylinders 13 are arranged and are positioned inside the base 1.
Fig. 3 shows the sail 7 of the device of the invention in a raised state, and the spatial structure of the sail support 6 is shown in fig. 4. The sail 7 rises from the sail bottom plate 5 along the vertical rods of the sail support 6, and under the action of the bent rods transversely arranged on the sail support 6, the sail 7 is supported towards the sailing direction of the ship to form a cambered surface, so that the sail can generate forward thrust by utilizing the Bernoulli effect.
As shown in fig. 5 and 6, the base top cover 2 is turned around a rotating shaft at one side, the hydraulic cylinder 13 is installed in the base 1 and is a power source which can be laid down to the stern, and two ends of the hydraulic cylinder 13 are respectively connected with the upper hinged support 11 on the base top cover 2 and the lower hinged support 12 inside the base 1. When the device is in use, the buckle 14 on the top cover 2 of the base is buckled with the clamping seat 15 on the base 1, so that the stability of the device is ensured; under the condition that the wind direction is not favorable for the use of the device, the buckle 14 is disengaged from the clamping seat 15, and the device disclosed by the invention can lie down towards the stern at 90 degrees under the thrust action of the hydraulic oil cylinder 13.
The relationship between the ship heading and the wind direction is shown in FIG. 7: setting the angle rotated from the ship sailing direction along the anticlockwise direction to the wind direction as theta, and judging that the ship is windy in the bow direction and sails against the wind when the theta is equal to 0 degrees, 45 degrees, U [315 degrees and 360 degrees ]; when theta is belonged to (45 degrees, 135 degrees, and U (225 degrees, 315 degrees), judging that the ship is in a side direction; when θ ∈ [135 °, 225 ° ], it is determined that the stern direction is coming wind.
When the stern direction winds, the wind power generation part of the device is used for generating power, and the sail 7 is in a retracted state and is not used. As shown in fig. 8, when the wind directly behind the ship, i.e., θ, reaches 180 °, the wind turbine 9 is perpendicular to the wind direction, so that the utilization rate of the wind energy is improved and the power generation effect of the device is improved. As shown in fig. 9, when θ e is 135 °, 180 ° or θ e is 180 °, 225 °, the wind direction sensor 10 collects wind direction information and transmits the wind direction information to the control system in the form of a signal, and the control system controls the hydraulic motor 3 to drive the sail rotating shaft 4 to rotate according to the received signal, so that the device of the present invention can rotate in a self-adaptive manner to the wind direction, and ensures that the wind turbine 9 can be perpendicular to the wind direction when wind comes at any angle in the stern direction, thereby maximally utilizing the wind energy and achieving an ideal power generation effect.
As shown in fig. 10 and 11, when θ ∈ (45 °, 135 °) ∈ (225 °, 315 °), that is, when the ship is facing the wind, the power generation portion forms an angle with the wind direction, the utilization rate of the wind energy by the device is low, and the power generation effect is poor. However, the device of the invention can lift the sail 7 when the ship is in a lateral wind direction, and utilizes the sail 7 to realize ship assistance to replace wind power generation. The wind direction sensor 10 transmits collected wind direction information to the control system, the control system controls the hydraulic motor 3 to drive the sail rotating shaft 4 to rotate, a plane formed on the rear side of the sail 7 is parallel to the wind direction, and the cambered surface of the sail 7 is arranged on one side of the bow. According to the bernoulli principle, the larger the flow velocity of the gas is, the smaller the pressure is, when the gas flow passes through the sail 7, the longer the distance the gas flow in front of the sail 7 takes to join with the gas flow behind the sail 7, so that the flow velocity of the gas flow in front of the sail 7 is large, the pressure is small, the flow velocity of the gas flow behind the sail 7 is small, the pressure is strong, and the pressure difference is generated between the front and the back of the sail 7. The pressure difference between the front and the back of the sail 7 can generate the combination along the normal direction of the cambered surfaceForce FPressure ofThe resultant force generates a forward decomposition force F in the direction of the length of the ship, which is in accordance with the direction of the ship's courseDriving forceAnd a sideward decomposing force F in the width direction of the shipSide forceForward force of decomposition FDriving forceThe ship is pushed to advance, and the boosting of the sail is realized.
As shown in fig. 12 and 13, when θ e [0 °, 45 ° ] [315 °, 360 ° ] is that the ship sails against the wind, the large-scale merchant ship is not suitable for sailing along the zigzag path, the wind sail 7 has little use value for boosting, and the device can lie down at 90 ° to the stern in order to eliminate the extra resistance brought by the device when the ship sails. The buckle 14 on the base top cover 2 is separated from the clamping seat 15 on the base 1, and the base top cover 2 drives the device to lie down towards the stern under the thrust action of the hydraulic oil cylinder 13, so that the device can not generate extra navigation resistance when being installed on a large commercial ship.
In conclusion, the device disclosed by the invention is applied to a large-scale navigation commercial ship, can be self-adaptive to the wind direction, and realizes the maximum utilization of wind energy. As shown in fig. 14, when there is a wind in the stern direction, electricity is generated by the wind turbine 9; when the ship is in a lateral wind, the sail 7 is used for assisting the ship; when wind blows in the direction of the bow, the device can lie down to the stern under the action of the hydraulic oil cylinder 13, and no additional sailing resistance is generated. The device can utilize the wind energy in the range of 270 degrees on both sides of the ship body and the stern, only the wind energy in the range of 90 degrees on the bow is not utilized, and the utilization range of the wind energy is very large, so the device has higher practical application value.
The wind power generation device captures wind energy to generate power, and the higher the height of the wind turbine 9 from the sea level is, the richer the wind energy resources are, and the better the power generation effect is. However, when the wind turbine generator is applied to a large-sized sailing merchant ship, the installation height of the wind turbine 9 is limited and the installation position is not too high in order to ensure the stability and the safety of the ship in the sailing process. Therefore, the device of the invention adopts the multiple wind turbines 9 to generate electricity, and the power generation effect of the device 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.
