Description

Technical Field

[0001] This invention belongs to the field of sail design and construction, and specifically relates to a bladeless sail device. Background Technology

[0002] Against the backdrop of green shipbuilding and energy conservation and emission reduction, wind-powered propulsion devices have become the mainstream wind-powered propulsion equipment, providing clean energy auxiliary power for ships. However, traditional airfoil blades have large areas and weights, resulting in a large workload for maintenance. The weight of the blades increases fuel consumption, and the wind energy utilization rate is low, which are the problems that this invention aims to solve.

[0003] A bladeless sail device suitable for marine applications is proposed, which significantly reduces the area of ​​the sail blades, reduces maintenance workload, improves wind energy utilization, and assists ships in propulsion. Summary of the Invention

[0004] To solve the above problems, this invention proposes a bladeless sail device, the technical solution of which is as follows:

[0005] A bladeless sail device includes a jetting device fixed above the main deck via a base. The base wall is composed of multiple regular hexagons, forming a honeycomb-like base wall. The jetting device has an annular main body, which is vertically arranged. The middle section of the annular main body is straight, and the two ends are arc-shaped sections. The annular main body is composed of an inner shell and an outer shell, which are connected by a connecting plate to form a hollow cavity. The inner side of the connecting plate is inclined towards the center to form an inclined surface with an inclination degree of 16°. A 1mm wide air outlet is opened on the surface of the connecting plate. An air inlet is provided at the bottom of the annular main body, and a top air outlet is provided at the top.

[0006] A centrifugal pump is fixed at the center inside the base. A rotating impeller is installed on the top of the centrifugal pump. A silencer is fixed above the centrifugal pump. The silencer has a silencer cavity. A drain pipe is connected to the center of the silencer cavity. The top of the drain pipe is connected to the air outlet. The silencer cavity is located on the top of the base. Its diameter is the same as the diameter of the base. An inner flange is fixed on the top of the silencer cavity. An outer flange is fixed on the bottom of the injection device. The inner flange and the outer flange are matched.

[0007] A gearbox is installed on the upper surface of the outer flange, and a gear shaft extends downward from the gearbox. The gear shaft penetrates the outer flange and extends into the inner flange. A gear is fixed at the bottom of the gear shaft, and a rack is installed on the inner surface of the inner flange. The gear meshes with the rack.

[0008] An input pump and control module are fixed to the upper surface of the outer flange, connected via hydraulic lines. The control module is supported on the outer flange by a bracket and connected to an output pump via hydraulic lines. The output pump is connected to the transmission shaft. The input pump and control module are connected via hydraulic lines, and the control module and output pump are connected via two hydraulic lines. The output pump's center is connected to a gear via a shaft, and the gear meshes with the inner flange for power transmission. The glycerin injection port is located on the side of the sliding bearing and is for lubrication of a round steel column.

[0009] Driven by the impeller of a centrifugal pump, air enters the base through the honeycomb-shaped base wall and is pressurized to 15-20 times its normal pressure. This pressurization pushes the air to the top drain pipe, through the air inlet into the hollow inner cavity, and out through the air outlet and top outlet. The outer wall of the cylindrical base has hexagonal honeycomb-shaped air inlets connected to the inner cavity. Driven by the impeller of the motor-driven centrifugal pump, air enters the inner cavity through these inlets and is pressurized to 15-20 times its normal pressure. This pressurization pushes the air to the top silencer, through the drain pipe, and into the injection device through a 3mm air inlet. The high-pressure air rises within the inner cavity and exits through a 1mm air outlet along the flow direction. The air outlet creates a pressure difference, driving airflow and propelling the ship forward.

[0010] Furthermore, in the aforementioned bladeless sail device, a conical reinforcing fixing plate is provided between the bottom of the jet device and the outer flange.

[0011] Furthermore, the aforementioned bladeless sail device has a reinforcing ring welded around the base on the lower surface of the main deck, with the reinforcing ring aligned with the base.

[0012] Furthermore, in the aforementioned bladeless sail device, the diameter of the air inlet is 3mm.

[0013] Furthermore, in the aforementioned bladeless sail device, a centrifugal pump is fixed on the main deck inside the base, and the centrifugal pump contains a first motor that drives the pump.

[0014] Furthermore, in the aforementioned bladeless sail device, the input pump is connected to a second motor.

[0015] This invention significantly reduces the area of ​​traditional sail blades, effectively lowering the workload of sail maintenance and reducing weight, thus lowering fuel consumption. The narrowed outlet design, with a width of 1m combined with a 16° inclined connecting plate, generates maximum airflow. The bladeless sail increases wind power by 15-20 times compared to traditional sails, improving propulsion. The bladeless sail can rotate horizontally to receive maximum wind force.

[0016] The design incorporates hexagonal honeycomb-shaped air inlets to increase air intake, and the control system allows for easy stopping during rotation.

[0017] The hydraulic valve remote control system ensures that the rotation speed, direction, start and stop are controllable, can ensure low-speed rotation of the equipment, and allows time for personnel to react in case of emergency. It avoids the safety hazard of personnel being hit by objects when the equipment is running. The design of this invention uses sliding bearings to cleverly solve the contradiction between the turning motion of the bladeless sail device and the dynamic and static requirements of the relative stillness of the main deck surface.

Detailed Implementation

[0024] The invention will be further described with reference to the accompanying drawings.

[0025] A bladeless sail device, such as Figure 1 , 2 As shown, the spraying device is fixed above the main deck via a base. A reinforcing ring is welded around the base on the lower surface of the main deck, aligning with the base. The base wall is composed of multiple regular hexagons, forming a honeycomb structure. The spraying device has an annular main body, vertically positioned with a straight section in the middle and curved sections at both ends. The annular main body consists of an inner shell and an outer shell, connected by a connecting plate. The inner and outer shells form a hollow cavity. The inner side of the connecting plate is inclined towards the center, forming an inclined surface with an inclination angle of 16°. A 1mm wide air outlet is opened on the surface of the connecting plate. A 3mm diameter air inlet is located at the bottom of the annular main body, and a top air outlet is located at the top.

[0026] A centrifugal pump is fixed at the center of the base, and the pump is mounted on the main deck inside the base. The centrifugal pump contains a first motor and is driven by the first motor. A rotating impeller is installed on the top of the centrifugal pump, and a silencer is fixed above the pump. The silencer has a silencer cavity, and a drain pipe is connected to the center of the silencer cavity. The top of the drain pipe is connected to the air outlet. The silencer cavity is located on the top of the base, and its diameter is the same as the diameter of the base. An inner flange is fixed to the top of the silencer cavity, and an outer flange is fixed to the bottom of the injection device. A conical reinforcing fixing plate is installed between the bottom of the injection device and the outer flange, and the inner flange and the outer flange are fitted together.

[0027] A gearbox is installed on the upper surface of the outer flange, and a gear shift shaft extends downward from the gearbox. The gear shift shaft penetrates the outer flange and extends into the inner flange. Figure 3 As shown, a gear is fixed at the bottom of the gearbox, and a rack is provided on the inner surface of the inner flange, with the gear meshing with the rack teeth.

[0028] Driven by the impeller of a centrifugal pump, air enters the base through the honeycomb-shaped base wall and is pressurized to 15-20 times its normal pressure. It is then pushed to the top drain pipe, enters the hollow inner cavity through the air inlet, and exits from the air outlet and the top air outlet. The outer wall of the cylindrical base has hexagonal honeycomb-shaped air inlets that communicate with the inner cavity. Driven by the impeller of a motor-driven centrifugal pump, air enters the inner cavity through the air inlets and is pressurized to 15-20 times its normal pressure. It is then pushed to the top silencer and enters the injection device through the drain pipe and a 3mm air inlet. The high-pressure air rises within the inner cavity and exits from the 1mm air outlet along the flow direction. The air outlet creates a pressure difference, driving airflow and propelling the ship forward.

[0029] An input pump and control module are fixed to the upper surface of the outer flange, connected via hydraulic lines. The control module is supported on the outer flange by a bracket and connected to an output pump via hydraulic lines. The output pump is connected to the transmission shaft. The input pump and control module are connected via hydraulic lines, and the control module and output pump are connected via two hydraulic lines. The output pump's center is connected to a gear via a shaft, and the gear meshes with the inner flange for power transmission. The glycerin injection port is located on the side of the sliding bearing and is lubricated by a round steel column. A second motor is connected to the input pump.

[0030] The cylindrical base has hexagonal honeycomb-shaped air inlets on its outer wall, which communicate with the inner cavity of the base. Air, driven by the impeller of a motor-driven centrifugal pump, enters the inner cavity through the air inlets and is pressurized to 15-20 times its normal pressure. This pressurized air is then pushed to the silencer at the top, and through a guide pipe, it enters the injection device via a 3mm narrow slit. The high-pressure air rises within the inner cavity and is discharged from a 1mm outlet along the guide direction. Figure 5 The air outlet creates a pressure difference, which drives airflow and propels the ship forward.
