Background technique

Wave energy is the most abundant type of clean energy contained in ocean energy. The specific form of wave energy is the huge forward thrust and upward buoyancy. With the human desire for and exploration of clean energy, the research on wave energy utilization technology has also made great progress, and a large number of research results have been obtained. These results are mainly used in the field of power generation. At present, the wave energy collection devices that have been completed or disclosed are mainly divided into two types: shore-based and floating. The shore-based wave energy acquisition device is greatly affected by the coastal terrain and ocean tides, and the construction and maintenance costs are high, which is not suitable for large-scale promotion. Because the floating wave energy acquisition device is not affected by the coastal terrain, and can be directly put into the target sea area after being manufactured on land, it has a strong adaptability to the working environment and low construction and maintenance costs, which has become the main research and development direction at present. The types of more mature floating wave energy collection devices are mainly air turbine type, wave raft type, wave pendulum type, oscillating float type, nod duck type, etc., because the nod duck type has horizontal thrust that absorbs waves simultaneously and upwards. The characteristics of buoyancy are high energy collection efficiency, while the wave energy collection method of other types of devices mainly absorbs the unidirectional force of wave energy, and the collection efficiency is low. The disadvantage of the nod duck is that most of its mechanical structure is located in the absorber and is below the horizontal level. The design requirements for the strength and airtightness of the absorber structure are very strict, it is difficult to adapt to the impact of large waves, and it is easy to form seawater infiltration. Leakage, causing damage. Because of the nodding duck-like structure, it has a high initial energy collection efficiency for the wave, but as the wave advances to the end, the angle between the duck's wavefront and the horizontal plane gradually increases, absorbing the upward buoyancy of the wave. The active surface of the device gradually decreases, which gradually reduces the collection efficiency of the device, so that the nod duck collection device has the disadvantage of high collection efficiency of low-energy waves, but low collection efficiency of high-energy waves. At present, a floating eagle-type wave energy power generation device with the characteristics of a semi-submersible ship has emerged. Chinese invention patent: CN102661231A. This invention discloses a new floating eagle-type wave energy power generation device with the characteristics of a semi-submersible ship.

The gate-shaped support arm together with the eagle-head wave-absorbing floating body can rotate around the first hinge. L-shaped underwater appendages are installed at both ends of the boat-shaped underwater appendage. The body is connected to the boat-shaped underwater appendage through a second hinge. The L-shaped underwater appendage can rotate around the second hinge. The main floating body is installed directly above the boat-shaped underwater appendage and below the eagle-head type absorbing floating body. The lower appendage is provided with a buoyancy compartment and an equipment compartment, and a buoyancy adjustment cabin is provided at the middle of both sides of the upper end of the ship's underwater appendage deck. The absorbing floating body of the invention is developed from a nodding duck type device, and the wave front of the absorbing floating body is improved. However, in order to increase the collection efficiency of high-energy waves, a gate-shaped support arm is added to the lower part of the absorbing floating body, thereby increasing In order to keep the floating rotation radius of the absorbing floating body, in order to keep the whole device stable during work, the volume of its underwater appendage is correspondingly increased, which makes the overall device expensive.

The advantages and benefits are:

1. The design of the device is based on the floating type, so that the entire device can be manufactured on land. After the completion of the device, it is placed in the target sea area and directly enters the working state without being affected by the tide and the coastal terrain. Compared with the shore-based type, Save costs and easy to promote.

The "nodding duck" type wave-absorbing surface The wave front of the floating body tends to stand upright under the impetus of the wave, and the area receiving the upward buoyancy of the wave gradually decreases. The wave-lifting front of the "climbing tail" tends to be horizontal under the impetus of the wave, and the area receiving the upward buoyancy of the wave gradually increases. The motion state of the "clipping tail" absorbing floating body is more suitable for absorbing the energy generated by the wave in the process of converting thrust to buoyancy, so the energy absorption efficiency of the "clipping tail" absorbing floating body is higher than that of the "nodding duck" type Wave-absorbing floating body.

4. In the case of the same area of the wave front, the working rotation radius of the "clipping tail" absorbing floating body is smaller than the "eagle type" absorbing floating body that is similar to the "nodding duck" type of motion, that is, the "clipping tail" The absorbing floating body does not need to adopt the gate-shaped bracket adopted by the "eagle-type" absorbing floating body to increase the absorption efficiency of high-energy waves. In order to maintain the stable state of the overall device in operation, the volume of the appendage required by the "clipping tail" wave absorbing float is smaller than the volume of the appendage required by the "eagle" wave absorbing float under the same wave conditions.

5. In the design scheme of the device, a wave-lifting plate is designed in the lower part of the wave-absorbing floating body, so that the wave-fronting surface of the wave-absorbing floating body, the attached bodies (or partitions) on both sides and the wave-fronting surface of the wave-lifting plate A close-closed space is formed in the direction, which makes the device achieve high wave energy collection efficiency.

6. The side attachments that provide the main buoyancy in this device are distributed on both sides of the absorber, and multiple absorber floats can be designed in the middle to collect wave energy at the same time. You only need to add the corresponding support frame and buoyancy compartment on the device. Provide sufficient buoyancy to support more absorbers for work. The design of this device has high cost performance and is conducive to industrialization.

A wave-lifting plate 5 is provided on the lower surface of the claw-type wave-absorbing floating body 1, and both sides of the wave-lifting plate 5 are respectively connected to the ship-type side attachments 3, and the front part between the pair of ship-type side attachments 3 is A front support frame 6 and a rear support frame 7 are fixedly connected to the rear part, respectively, and a door-type bracket 8 is also connected between the pair of ship-shaped side attachments 3, and the lower ends of the pillars of the door-shaped bracket 8 are fixedly connected to each other. To the top of the boat-shaped side appendage 3. A hydraulic cylinder 10 and a piston rod 11 matched with the hydraulic cylinder 10 are provided between the upper cross beam of the gate-shaped bracket 8 and the flat rear surface of the tilted-wave absorbing floating body 1. The upper end of the hydraulic cylinder 10 is hinged on the crossbeam of the gate-shaped bracket 8, and the lower end of the piston rod 11 is hinged to the flat rear surface 1.2 of the tilted-wave absorbing floating body 1, which is a hollow shell structure.

In order to facilitate the wave-absorbing absorbing floating body to absorb wave energy, a preferred embodiment of the present invention is that the wave-absorbing absorbing floating body includes a curved front wave front 1.1, a flat rear 1.2, a curved bottom 1.3, and a fan shape. The two side surfaces 1.4 and the arc-shaped upper end surface 1.5, of which the 1/3 to 1/2 of the arc-shaped front wave front surface 1.1 are set above the water surface and have a bending radius greater than that below the water surface, said arc-shaped bottom surface 1.3 and the arc-shaped upper end 1.5 are both arc-shaped surfaces with the center line of the transmission shaft 2 as the center, and the flat-shaped rear surface 1.2 is above the water surface.

Preferably, the arc-shaped forward wave front 1.1 is an arc surface that is recessed from the middle to the inside of the claw-shaped wave-absorbing buoyant body 1 and has a gradual bending radius. Under the condition that the seawater is static, this The tangent plane of the arc surface at the intersection with the horizontal plane forms an angle of 45 ° with the horizontal plane, and in the process that the front wave front of the arc surface gradually rises upward and backward, all the tangent planes at the intersections with the horizontal plane are formed. Form an included angle of 45 ° with the horizontal plane, all the way to the lowest end of the arc-shaped frontal wavefront.

In order to facilitate the wave-absorbing absorbing floating body to absorb wave energy, a further preferred embodiment of the present invention is that the wave rising plate 5 is divided into the upper section 5.1 of the wave rising plate and the lower section of the wave rising plate according to the line shape of the wave wave side view. 5.2 The upper part of the wave-front of the rising wave plate 5.1 is a circular arc surface with the center line of the transmission shaft 2 as the center. This circular arc surface is raised in a circular arc shape from the downward direction of the tail-shaped absorber 1 to the rear. The radius of the arc surface is greater than the radius of the arc surface of the arc-shaped bottom surface 1.3. The lower section 5.2 of the rising wave facing surface is the upper section 5.1 of the rising wave facing surface. The bottom section is the front-bottom direction from the inside of the ship-shaped side appendage to the upper back. It is gradually raised to the inclined plane at the lower part of the tail-cushioning wave-absorbing floating body 1, the arc surface 5.1 and the lower section 5.2 of the wave-fronting surface are tangent at the lower side of the tail-closing wave-absorbing floating body 1 and connected as a whole.

In order to avoid the transitional swing of the tail-cushion-type absorbing floating body 1, a further preferred embodiment of the present invention is that the height of the upper section 5.1 of the wave-lifting wave front is lower than that of the wave-closing-type absorbing floating body 1.1 lower end which floats backward. At the limit working height, the gap between the upper end 5.1 of the upper side of the wave front of the lower attachment plate and the limit working height floating backwards at the bottom end 1.1 of the wave front absorbing floating body is the wave overflow 9.

In order to minimize the energy loss caused by the waves passing through the gap between the wave-lifting plate 5 and the tail-cushion-type absorbing floating body 1, a further preferred embodiment of the present invention further has a curved bottom surface of the tail-cushion-type absorbing floating body 1. The gap between 1.3 and the arcuate surface of the upper section 5.1 of the wave-front surface is 1mm ~ 5mm, and the gap between the fan-shaped wave-absorbing buoyant body's two sides and the pair of ship-shaped side attachments is 1mm ~ 5mm.

In order to facilitate the adjustment of the height of the overall device floating on the water surface and maintain stability, a further preferred embodiment of the present invention is that the floating bodies of the pair of boat-shaped side attachments 3 are arranged in the forward and backward directions respectively, and are arranged side by side on the Both sides of the tail-type absorbing floating body 1. A pair of ship-side attachments 3 are divided into upper and lower parts, the upper part is the ship-side attachment equipment compartment 3.1, and the lower part is the ship-side attachment buoyancy compartment 3.2. The buoyancy chamber 3.2 is semi-submerged in seawater, and the front and rear ends protrude from the front and rear ends of the equipment compartment 3.1 below. Multiple air chambers are distributed in the front and rear directions in the buoyancy chamber 3.2. The upper part of the air chamber is equipped with an intake pipe and an exhaust pipe. Install water inlet and drain pipes.

In order to facilitate the conversion of wave energy into electrical energy or pressure energy through transmission mechanisms of different structures, a further preferred technical solution of the present invention is that the transmission shaft 2 is connected to an energy conversion device through a transmission gear 14, and the energy conversion device It is provided in the upper part above the water surface of the ship-shaped side attachment 3.

The front view of the tilted-type absorbing floating body 1 is square, the side view is small in the front upper part, and the rear part is large, similar to the shape of an eagle head, and the overall structure is a hollow closed cabin. The lower part of the tail-absorbing absorbing floating body 1 is partially floating in the water, and is driven by waves to swing around the centerline of the transmission shaft 2 as an arc. The main function is to absorb the mechanical energy generated by the wave surge.

In addition to part of the buoyant body of the ship-shaped side attachment 3, the equipment compartment 3.1 provides space for the energy conversion system, control system and other auxiliary equipment of the device, in addition to providing partial buoyancy. The upper half of the equipment compartment floats above the water level. The main function of the buoyancy module 3.2 is to provide buoyancy and adjust the overall device. The length of the front and rear protruding parts of the buoyancy tank 3.2 should meet the conditions to keep the overall device stable under the surge of waves and avoid longitudinal shake of the entire device.

The height of the rising surface of the wave-fronted wave-absorbing buoyant body 1 at the top of the wave front 1.1 is not lower than the height of the wave under the maximum rated operating state of the device.

The main body front support frame 6 and the main body rear support frame 7 are composed of a plurality of sets of brackets. The main function is to connect a pair of boat-shaped side attachments 3 to form a solid and stable structure for the overall device and provide support points for auxiliary devices. The arrangement of the main body front support frame 6 and the main body rear support frame 7 must not affect the normal operation of the tilted tail type absorbing floating body 1.

The main function of the gate-shaped bracket 8 is to provide an upper fulcrum for the hydraulic cylinder 10. The role of the hydraulic cylinder 10 is to convert the mechanical energy of the wave surge into hydraulic energy through the up and down swing of the rear and lower wave absorber 1. Since the lower part of the rear end of the wave-absorbing type absorbing floating body 1 is semi-floating on the water surface, and has a certain mass itself, the efficiency of using the bidirectional hydraulic cylinder will be higher.

The arc-shaped design of the wave-fronted wave-absorbing surface 1.1 on the front side of the tilted-type wave-absorbing floating body 1 is an arc-shaped curved surface that is recessed from the top to the inside of the wave-typed wave-absorbing floating body 1 in the middle. This curved surface enables the angle of the wave's force on the tail-cushioning absorbing floating body 1 to be maintained during the swinging of the tail-closing absorbing floating body 1 upward and downward when the wave pushes the tail-closing absorbing floating body 1 under the rated working state. In optimal condition.

The optimal height of the uppermost end of the curved bottom surface 1.3 is flush with the water surface under static conditions. The curved surface enables the tilted-wave absorber 1 to swing around the transmission shaft 2 without causing the rear seawater to generate wave resistance for the swing of the tilted-wave absorber 1, which can improve the device's absorption efficiency of wave energy. .

The wave-lifting plate 5 is designed to achieve sufficient strength so that it can withstand the impact of waves. The front and bottom of the wave-lifting plate 5 are firmly connected to the adjacent front support frame 6 of the main body, and the rear and bottom are connected firmly to the main back support frame 7 through a link. The clearance between the two sides of the tilted-wave absorbing floating body 1 and the inside of the boat-shaped side attachment 3 and the clearance between the rear lower part of the tilted-wave absorbing floating body 1 and the lower plate 5 of the main body must be achieved under the condition that no friction occurs with each other The smallest, 1mm ~ 5mm, is used to reduce the energy loss caused by waves passing through the gap.

In order to improve the performance-price ratio of the overall device, this embodiment further designs and installs a plurality of tail-shaped wave-absorbing buoys 1 between a pair of ship-shaped side attachments 3, and the tail-wave-type absorbing floats 1 are separated by a partition 12 . The partition plate 12 is an upright plate-like structure, which is arranged forward and backward. The front and rear ends of the partition plate 12 are fixedly connected to the main body front support frame 6 and the main body rear support frame 7, respectively. The left and right sides of the partition plate 12 are perpendicular to the wave plate 5. , And the bottom is fixedly connected to the rising plate 5. The upper part of the partition plate 12 is above the water surface, and the upper plane is parallel to the water surface. The left and right widths of the upper plane need to meet the needs for installing the bearing support 4 and the door-shaped bracket 8. The bottom of the gate-shaped bracket 8 is installed on the top of the partition plate 12 to form a stable structure. The front upper part of the tilted-wave absorber 1 is installed on the top of the partition plate 12 through the transmission shaft 2 and the bearings and bearing supports 4 on both sides. The function of the partition plate 12 is to provide a fulcrum for each of the tail-closing wave absorbing bodies 1 and related components, and to separate each of the tail-closing wave absorbing bodies 1 so that the wave energy does not spread to both sides and avoid mutual interference waves. The partition plate 12 is designed as a hollow enclosed cabin, which can provide partial buoyancy for the overall device.

A buoyancy tank 13 can be added to the lower part of the wave lift plate 5. The buoyancy compartment 13 is arranged horizontally on the left and right sides, and is a hollow and enclosed cabin body, and the two sides are respectively connected with a pair of ship-shaped side attachments 3. The lower part and the rear part of the buoyancy tank 13 are connected and fixed to the main body front support frame 6 and the main body back support frame 7 by connecting rods. The cartridge 13 may be divided into a plurality of buoyant air chambers, upper chamber intake pipe installation, an exhaust pipe, a lower mounting inlet, drain, for adjusting the size of buoyancy. The buoyancy tank 13 can be connected to the wave plate 5 and designed as a whole. Function: Provide partial buoyancy for the whole device.

The anchoring system 15 connects a pair of ship-shaped side appendages 3 to the sea floor, and the whole device is fixed on the sea level fixed in the direction of the front side of the wave toward the wave front. The anchoring system can use the existing technology, and will not be described here.

The hydraulic energy storage, conversion and control system is arranged in a pair of ship-shaped side appendages 3, and is connected to the hydraulic cylinder 10 through a hydraulic pipeline, and the hydraulic energy collected by the hydraulic cylinder 10 is utilized. The hydraulic energy storage, conversion and control system, and various utilization methods related to hydraulic energy can be implemented by those skilled in the art using existing technology, which will not be described here.
