Description

The present invention mainly relates to a rotor blade with a shroud used for flight of an aircraft, a part of a large blower, etc., or a wind power generator using a peripheral speed, a metal, ceramic, cermet, etc. having a thickness of 0.01 mm to 5 mm. A ribbon or thin strip of fiber or synthetic resin (hereinafter referred to as “thin strip”) or a rubber or silicone strip of 0.1 to 50 mm in thickness, including any overlap, can be selected. If a circular strip, rotating duct, or shroud is formed by laminating thin strips by performing at least two rounds, and the thickness in the radial direction is made of metal, ceramic, cermet, fiber, or synthetic resin, 2 mm In the case of metal, ceramic, cermet, fiber, synthetic resin, rubber, or silicon An annular, rotation duct and the shroud, characterized in that without a vertical plate portion that relates to instruments and Preparation for creating it.

The rotor blades with shrouds described in Patent Literature 3, Patent Literature 4, Patent Literature 5, and Patent Literature 6 generate torque at the blade tip that serves as a driving force for rotating the rotor blade, and are described in Patent Literature 2. A wind turbine generator that electromagnetically uses a peripheral speed has permanent magnets that generate a magnetic field disposed on the outer periphery of an annulus or a rotating duct, and a power generation coil disposed on the inner periphery of a shroud that surrounds the periphery. Inductive current is generated from the relative speed of the power to generate electricity. Therefore, in any case, the larger the diameter, the more efficiently torque generation and power generation can be performed.

The wind turbine generator mechanically utilizing the peripheral speed of Patent Document 1 has a diameter much smaller than the diameter of the ring on the side surface and the outer periphery of the ring that connects the blade tips of the wind turbine blades and rotates together with the blades. Since the ring and the tire are brought into contact with each other and the circumferential speed of the ring is mechanically taken out as a driving force for rotating the generator to generate electric power, even in Patent Document 1, a ring with a larger diameter can generate power more efficiently.

The ring used in Patent Document 1, the ring used in Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, and Patent Document 6, the rotating duct, and the shroud are made of materials that are relatively easily available. In the case of making only a very simple process, a ring, a rotating duct, and a shroud can be created by cutting a portion of the seam steel pipe into a ring. For example, if the material is steel, carbon steel, alloy steel, or stainless steel with a thickness of about 4 mm to about 26 mm, a maximum diameter of about 660 mm is readily available. Some are about 2.7m. Therefore, if it is a spiral seam pipe made of steel having a thickness of about 4 mm to about 26 mm, the ring, rotary duct, or shroud used in Patent Document 1 to Patent Document 6 can be obtained by carrying out a mild process after cutting the ring. When the diameter is about 2.7 m or less, it can be produced relatively easily.

In addition, an annular ring, a rotating duct, or a shroud having a diameter exceeding about 2.7 m, for example, when a seam tube having a diameter of 26 mm and a diameter of 660 mm is extended while being processed to a thickness of 4 mm by cold rolling or hot rolling. In the case of up to about 4.3m in diameter, it is possible to obtain a circular ring, a rotating duct or a shroud up to about 8.6m in diameter when processed up to 2mm thick, and with a wall thickness of 26mm and a diameter of 2.7m When a spiral seam tube is stretched to a thickness of 4 mm by cold rolling or hot rolling, it is up to a diameter of about 18 m. When it is stretched to a thickness of 2 mm, it is a ring or rotating duct up to a diameter of about 35 m. And shrouds can be created.

Since the seam pipe is created by welding one place around the circumference of the pipe, welded parts that have almost no problems when using the seam pipe as a pipe with a long length can be cut into rings and the length is longer than the diameter. When shortened, the welded part forms a weak point that easily shears depending on the load. In this case, if the material of the seam pipe is the same kind of metal such as steel, carbon steel, alloy steel, stainless steel, etc., prepare multiple cut seam pipes for cold rolling or hot rolling. If the welding parts are laminated so that they do not overlap by using the difference in expansion coefficient due to different temperatures, the risk of the welding parts shearing due to the load can be reduced, and at the same time, the thickness of the thickened parts by the lamination Can be further rolled to increase the diameter of the ring, rotating duct, and shroud. If such a method is used, assuming that a spiral seam pipe having a wall thickness of 26 mm and a spiral seam pipe having a diameter of 2.7 m is made of four layers, if the roll can be rolled up to a thickness of 4 mm ideally only in the circumferential direction, When rolling up to a diameter of about 70 m and a wall thickness of 2 mm, an annulus, rotating duct or shroud up to a diameter of about 140 m can be created.

Furthermore, when creating a large-diameter ring, rotating duct, or shroud, prepare a thin plate with the required width from the beginning, weld one circumferential point, and shape it by rolling. Large circular rings, rotating ducts, and shrouds can be created with no limit in size. However, when laminating to eliminate the weakness of the welded part, steel, carbon steel can be used as materials for rings, rotating ducts and shrouds because of the degree of expansion and contraction due to temperature and the presence of physical properties that can be rolled. It will be limited to the same kind of metal such as alloy steel and stainless steel, and non-ferrous metal such as copper and titanium, and other materials such as ceramic, cermet, fiber, synthetic resin, rubber and silicon It was extremely difficult to use objects having different characteristics from the above. Furthermore, in the case of rolling as well, the rolling device when actually used for metal is a ring rolling device equipped with a mechanism capable of rolling only in the circumferential direction while minimizing the protrusion in the direction parallel to the rotation axis. Alternatively, instead of allowing protrusion in the direction parallel to the rotation axis during rolling, rolling is performed using a material with a thickness and width that allows the protrusion to be cut, and the protrusion is cut off and shaped at the end of rolling. It is necessary to be a ring rolling device provided with a device. In the former case, it is complicated and expensive, and in the latter case, extra man-hours and waste of materials are generated.

Japanese Patent Application No. 2007-027443 Japanese Patent Application No. 2006-343765 Patent No. 3946755 Patent No. 3793545 Japanese Patent No. 36777748 Japanese Patent No. 3595988 Japan Science and Technology Agency, “Successfully developed ultra-high-precision laser rangefinder that measures at high speed (within 10 microns error even when measuring 10 km)”, [online], [May 8, 2007 search], Japan Science and Technology Agency No. 334, September 7, 2006, Internet <http: // www. jst. go. jp / pr / info / info334 / index. html>

When creating circular rings, rotating ducts, and shrouds for use with rotor blades with shrouds and peripheral speed wind power generators for flight, even with a diameter of up to about 2.7 m, for example, a spiral seam tube can be cut into rings. Since it can be created, cost effectiveness (cost performance) was good. However, if it has a diameter of about 2.7 m or more, there are problems in processing in a rolling machine, problems in which the material is limited to a material that can be rolled, and so on. It is not easy to select and create an annulus, rotating duct or shroud. Therefore, any material including metal, ceramic, cermet, fiber, synthetic resin, rubber, and silicon can be used regardless of whether the diameter exceeds about 2.7 m, and even a few hundreds or even 1,000 m. It is a problem to easily create a ring, a rotating duct, and a shroud having a desired strength.

In the present invention, a metal, ceramic, cermet, fiber, or synthetic resin having a thickness of 0.01 to 5 mm is used in the production of a ring, a rotating duct, or a shroud used for a rotor blade with a shroud for flight or a wind power generator using a peripheral speed. A thin strip of 0.1mm to 50mm thick rubber or silicon, and a huge winding wheel (hereinafter referred to as "giant winding wheel" or "giant spinning wheel composition") to wind this thin strip If the thickness in the radial direction is made of metal, ceramic, cermet, fiber, or synthetic resin, the metal or ceramic Or cermet, fiber, synthetic resin, rubber, silicon, etc., the diameter is 2. Even if it is a big thing of more than m, or even a huge thing of several hundred meters or more than 1,000m and several kilometers, using an arbitrary material, a ring, a rotating duct or a shroud with sufficient strength can be used. Can be easily created.

When thin strips are stacked to form an annulus, a rotating duct, or a shroud as in the present invention, three effects are obtained. The first is to eliminate the weaknesses of the welds seen in conventional seam pipes in the longitudinal plate part that circulates on the circumference approximately parallel to the rotation axis of the ring, rotating duct, or shroud. For example, in the case of an annulus, a rotating duct or a shroud made by rolling and shaping a conventional 4 mm thick 2.7 m seam steel pipe into a ring, a depth of 4 mm is formed at a part of the circumference. It has the weak point of a welded part. However, in the present invention, a thin strip of the same material of 0.1 mm is continuously laminated around the giant winding wheel for 40 turns, and the entire circumference between the thin strips is joined by adhesion or pressure bonding, or at least the start point and the end point are joined. When joining and shaping to a 4mm thick 2.7m ring, rotating duct or shroud, there is virtually no welded part, so seamless pipes that are only in extremely small diameter pipes were cut into rings. It will have the same strength as the case. Also, even if it is made by laminating and winding different metals, ceramics, cermets, fibers, synthetic resins, rubber, or silicon with a thickness of 0.1 mm for each turn, if they are placed so that the so-called welded parts do not overlap The depth equivalent to the welded portion is 1/40 compared to an annular ring, a rotating duct or a shroud made from a conventional seam tube, so that it is much stronger against stress from a direction parallel to the rotating direction. . The second is that a ring, a rotating duct, and a shroud can be created by laminating optimum materials by arbitrarily selecting and combining materials that can be formed into thin strips. For example, in the case where the materials of the thin strips that have been rotated 40 times are all the same type of metal, the thin strips can be brought into close contact with each other by pressure welding or pressure bonding such as welding, welding, or rolling. In addition, even if the thin strips that have been rotated 40 times are different metals or ceramics, the thin strips can be closely adhered to each other by either bonding using an adhesive, welding, welding, welding including pressure welding or crimping. This makes it easy to create an annulus, rotating duct, and shroud that can withstand large stresses from the direction parallel to the rotation axis while making the most of the characteristics of the material while reducing the weight. It becomes. Thirdly, as long as there is a lot of space on the manufacturing site, it is possible to easily create a ring, a rotating duct or a shroud having a large diameter of several kilometers, as well as a large diameter of several hundred meters. is there. In particular, when a rotor blade with a shroud having a diameter exceeding 1 km can be produced when the aircraft is used for flight, it is remarkably used because there is no stall speed instead of a normally used lift blade with a stall speed. Since a drag blade that can generate lift even at a low rotational speed can be used for the rotor blade, it is possible to realize an aircraft that uses energy more efficiently.

The present invention relates to a rotating blade with a shroud to be used for flight, an annular ring (10) or a rotating duct (used for a wind power generator that uses a peripheral speed of a windmill electromagnetically or mechanically to generate power). 20) and shroud (30), as shown in FIGS. 1 to 6A, the main part of the ring (10), the rotating duct (20) and the shroud (30) is formed. The aim is to find out how strongly and easily the vertical plate part (130) can be made.

There are roughly three things to prepare for practicing the present invention. The first is a thin strip in the form of a strip of metal, ceramic, cermet, fiber, synthetic resin, rubber or silicon, which is the material of the ring (10), rotating duct (20) or shroud (30) ( 100). If the material is metal, ceramic, cermet, fiber, or synthetic resin, the thin strip (100) is selected from 0.01 mm to 5 mm thick, and 0 for rubber or silicon. Prepare by selecting from 1mm to 50mm thick. The second is a giant winding wheel (200). The giant winding wheel (200) has a donut-like shape with an outer peripheral portion having a diameter of about 2.7 m or more, and in some cases, the diameter is as large as several kilometers. Usually, the donut-shaped part is divided into parts that become a part of eight or more giant winding wheels (hereinafter referred to as “giant winding wheel parts” or “giant spinning wheel potions”) and combined as necessary. Used as a huge winding car (200). Therefore, for example, when the giant winding wheel (200) having a diameter of 3 m is equally divided into eight, the length in the direction of forming the circumference of the giant winding wheel part (210) is about 1 m, The plan view is similar to the shape of the paper part that was stuck to catch the wind with a Japanese fan. In addition, when a giant winding wheel part (210) having a circumferential length of about 1 m is used for a giant winding wheel (200) having a diameter of 3 km, 9,424 giant winding wheel parts (210) are used. In the case of a giant windmill part (210) having a length of about 0.5 m, 18,848 giant windmill parts (210) are used. For the material of the giant winding car part (210), select a single material from steel, carbon steel, alloy steel, stainless steel, non-ferrous metals such as copper and titanium, ceramic or cermet, or combine multiple materials create. The third is a working environment in which the temperature and humidity can be adjusted. In the case of a huge winding car (200) with a diameter of about 3 m, the air conditioning equipment that does not matter so much, but when the diameter of the huge winding car (200) reaches several kilometers, the temperature of all the areas covering these It is almost impossible to keep the humidity constant, and the use of energy is not efficient. Therefore, the working environment is usually covered with a greenhouse (900) found in greenhouse cultivation. The greenhouse (900) may have a double structure or a triple structure as necessary.

The giant winding wheel (200) described as the second to be prepared is made of metal, ceramic or cermet, and is circular and the outer diameter exceeds about 2.7m. It is a donut-shaped shape extending several kilometers. Therefore, since the whole has a large volume and weight, at least about 8 parts are used in combination with those produced as a giant winding wheel part (210) that becomes a part of an arc having a length of 1 m or 50 cm.

The giant winding wheel part (210) has a front side that constitutes the outer periphery of the arc of the giant winding wheel (200) and a back side that constitutes the inner circumference, and the front side includes an annular ring (10) and a rotating duct (20 ) And the shroud (30), a substantially flat surface parallel to the rotation axis is formed. However, depending on the shape of the annular ring (10), rotating duct (20), or shroud (30) to be created, the outer peripheral portion may form a convex surface in a direction away from the center of rotation, or conversely, a concave surface. .

The front side of the giant winding part (210) is flat and nothing, but there is a giant winding on the back side, upper side and lower side other than the front side, the side of the adjacent giant winding part (210) side, or inside the cross section. A connecting device (220) for connecting the car parts (210) to form a giant winding car (200), a support hole ((211), (212)) for holding the giant winding car (200), For holding the tongue piece for fixing the starting point end point tongue piece (120) for fixing the starting point, the end point / starting point of the middle position of the thin strip (100) to be wound, and the end point at the end of winding, to the giant winding wheel part (210) Used to measure the change in diameter of the giant winding wheel (200) with the light wave / laser range finder (800) when the strip (100) is wound around the bolt hole (213) and the giant winding wheel (200). Light wave / laser reflector ( It is equipped with a 30).

The connecting device (220) connects adjacent giant-wound wheel components (210) to each other, and has at least one each in the side surface direction of each giant-wound wheel component (210). The surfaces of the giant windmill parts (210) connected to each other by the coupling device (220) are usually flat surfaces parallel to the diametrical direction, but the adjacent giant windmill parts (210) are fitted to each other. A combination of convex and concave or other shapes may be used as long as they can be brought into close contact with each other. The connecting device (220) includes a bolt (221) and a nut (222), and the connecting device (220) can be tightly connected by the action of the nut (222). It is also possible.

The prepared first sheet strip (100) is wound around the second prepared giant winding wheel (200), but the giant winding wheel (front side) (210) is usually smooth and smooth. If it is a plane, the starting point of winding of the thin strip (100) cannot be fixed. Therefore, a starting point end point tongue piece (120) having a tongue piece paste margin part (124) for joining the starting point of the thin strip (100) is prepared, and this starting point end point tongue piece (120) is used as a giant winding wheel part. (210) The tongue piece holding bolt hole (213) is fixed to the giant winding wheel (200), and the starting point of the thin strip (100) is joined to the tongue piece adhesive margin (124) of the starting point end point tongue piece (120). Then start winding. For the start / end tongue piece (120), after winding the thin strip (100) around the giant winding wheel (200), the joint portion is removed and pulled out, or only the portion protruding from the thin strip (100) is cut out and shaped. And finished product. There are two types of start point / end tongues (120), one single type start point / end tongue (121) and two sets of start point / end tongues (122). Mainly used when using the same type of strip strip (100) from the start point to the end point without changing the strip strip (100) for each turn, the latter changing the type of strip strip (100) every few turns Mainly used when doing.

The thin strip (100) with the starting point fixed to the giant winding wheel (200) circulates around the outer periphery of the giant winding wheel (200) while being adjusted by the tension controller (300) that can adjust the strength of winding. A plate portion (130) is formed to constitute an annulus (10), a rotating duct (20), and a shroud (30). At this time, in order to increase the strength of the wound thin strip (100), the entire region or places between the thin strips (100) are joined. For joining, joining with an adhesive, welding, welding, pressure welding, or pressure bonding is used. Explosive pressure welding (explosion) using a clay explosive (740) can also be used as the pressure welding method.

The material of the strip strip (100) can be selected from metal, non-metal, ceramic, cermet, fiber, synthetic resin, rubber and silicon according to the purpose, and usually a strip strip without mesh (no mesh) Although it is (101), if necessary, weight reduction can be achieved by using a thin strip (with mesh) (102) having a mesh in several layers around the circuit.

The winding work performed by preparing the thin strip (100) described as the first and the giant winding wheel (200) described as the second can also be performed by placing each material directly on the ground. is there. However, work such as tightening and separation of the giant winding wheel (200), work of winding the rolled strip (100), and rotating duct (20) and shroud (30) using the shaping roller (400) It is desirable that the working environment is a certain height from the ground in the shaping work to be performed. Therefore, the roll-shaped sheet strip (100) is installed on a sheet strip roll base (500) having a ground height that matches the height of the person's back, and the giant winding car (200) is also a person's back. It is installed and used on a column device (600) having a ground height that matches the height of the ground.

Usually, the strut device (600) can travel on the outer periphery of the strut device, for example, on a rail, using a fixed strut device (fixing method) (610) that can be finely corrected but cannot be moved greatly. The movable thin strip roll base (movable method) (510) is used. In this case, when preparing a plurality of types of sheet strips (100), a plurality of sheet strip roll stands (movable systems) (510) can be arranged on the rail. This method can be configured even when the diameter of the giant winding wheel (200) is several kilometers.

When the diameter of the giant winding wheel (200) is up to about several hundreds of meters, the roll-shaped sheet strip (100) is used as a sheet strip roll base (fixed method) (520), and the giant winding wheel (200) It is also possible to use a column device (movable method) (620).

The diameter of the giant winding wheel (200) is tightened as the wrapping around the thin strip (100) is advanced, and usually decreases. The degree of diameter reduction is determined by measuring the change in the distance to the lightwave / laser reflector (230) attached to the giant winding car part (back side) (210b). The distance is measured by placing a light wave / laser distance measuring device (800) in the center of the giant winding wheel (200) and transmitting / receiving the laser, or sending the light wave or laser to the light wave / laser reflector (230). Measure by guiding with optical cable (820), or place a precision distance measuring device (for short distance) (830), which is a small transmitter / receiver of multiple light / lasers, in close proximity to the light wave / laser reflector (230). Set and send / receive and measure. Based on the result, it is calculated by a computer, the rotation angle of the nut (222) of the coupling device (220) is determined, and a wrench, spanner, etc. are used to normally perform forced separation and correct distortion, etc. Depending on the special situation, it is tight. Further, when the work is carried out without the forced separation by the nut (222) of the coupling device (220) when the sheet strip (100) is circulated, the ring (10), the rotating duct (20), the shroud, When the creation work of (30) is finished, even if the giant winding wheel (200) is removed from the ring (10), the rotating duct (20), or the shroud (30) of the creation, Since (200) is tightened and cannot be removed, the nut (222) of the coupling device (220) is finely formed in the work of making the ring (10), the rotating duct (20), and the shroud (30). The correction work is particularly important.

The thin and long strip (100) expands and contracts depending on temperature and humidity conditions. Therefore, the work wound around the giant winding wheel (200) requires an environment in which the temperature and humidity are constant and the incidence of sunlight is not changed. When creating an annulus (10), rotating duct (20), or shroud (30) having a diameter of several kilometers, it is difficult to prepare these environments by constructing a normal building. Therefore, the environment of constant temperature and humidity to be prepared as the third uses a greenhouse (900) used in greenhouse cultivation or the like. The greenhouse (900) may have a double structure, a triple structure, or a structure having more than one structure in view of the correlation with the external environment.

5 and 6 show a rotor blade with a shroud that has a diameter of more than 2.7 m for flight, and FIGS. 1, 2, 3, and 4 have a diameter of more than 2.7 m for wind power generation. Wind turbines that use peripheral speeds, and in each of the rings, rotating ducts, and shrouds that are used in each, a strip of metal, ceramic, cermet, fiber, or synthetic resin having a thickness of 0.01 mm to 5 mm, 0 .Rubber or silicon sheet strips with thicknesses from 1 mm to 50 mm are selected arbitrarily, including duplication, and at least two rounds are made to form a stack of sheet strips to form a ring, rotating duct or shroud If the thickness is made of metal, ceramic, cermet, fiber or synthetic resin, the thickness is 2 mm or more. Metal, ceramic, cermet, fiber, synthetic resin, rubber or silicon If made of is approximately embodiment of the annular or rotational ducts and shrouds, characterized in that parallel to the no a vertical plate portion formed around the upper circumference to the rotary shaft having a lamination thickness of not less than 4 mm.

10, 11, 12, and 13 have a front side and a back side, and the front side has an arcuate shape and is adjacent to a connecting device having bolts and nuts for connecting and arranging a large number. 2 or more in total at both ends in the direction to be connected, and by connecting adjacent items together and arranging the total number, a donut-shaped circumference having a diameter of about 2.7 m or more is formed as a whole. It is an Example of a huge winding wheel part characterized by becoming a huge winding wheel for winding 1 sheet strip.

7, 8, and 9 show a giant winding wheel for winding the thin strip of Example 1 having a diameter of about 2.7 m or more in which giant winding parts of adjacent parts of Example 2 are connected by a connecting device. This is an example.

15, 16, 17, 18, 19, 20, 20, 21, 22, 23, 24, 25, 26, 27, and 28 are the strips of Example 1. FIG. The step of fixing the starting point to the giant winding wheel of the third embodiment, the step of winding the sheet strip with the starting point fixed to the giant winding wheel around the giant winding wheel two or more times, and the entire region between the sheet strips to be wound are joined. Implementation of a method of creating an annulus, a rotating duct or a shroud, including the step of fixing between the strips, either by joining points or joining only the start and end points It is an example. Although only explosive pressure welding (explosive welding) is shown as an example of the joining between the thin strips, other methods, for example, joining techniques using a synthetic resin adhesive or spot welding are well known. Illustration is omitted.

When a circular ring, a rotating duct, or a shroud is made by winding a thin strip of the present invention around a giant winding wheel two or more times and creating a vertical plate portion that is the main part of the circular ring, rotating duct, or shroud, Compared with the method of making an annulus, a rotating duct, or a shroud by welding or rolling, the strength of the vertical plate can be dramatically increased, and an extremely large diameter can be easily made. Therefore, a rotating blade with a shroud that can generate torque efficiently with a larger diameter, and a wind power generator that uses a peripheral speed that can generate power more efficiently with a larger diameter can be equipped with a ring or rotating duct or shroud of the desired size. Since it can be created and provided at low cost, energy can be used effectively.
