Description

Apparatus and installation method for tidal current and water power generation structure {A TIDAL CURRENT GENERATOR}

The present invention relates to an algae and a water flow generating structure device and a method for installing the aberration generator to enable the algae and water flow generation. More specifically, the propeller rotates according to the current and the current for the power generation of the current and the current will be installed a structure that can operate the water turbine generator. To this end, a barge equipped with a drilling machine for digging up to the rock bottom of the sea bottom or river bottom is fixed to the sea or river water, and then the excavation hole is formed in the sea bottom or river bottom, and the hollow casing is inserted into the inside and the hollow. After inserting and installing the reinforcement bundle inside the casing, the grouting material is injected from the lower part through the trempipe to cure to form a cylindrical support to which the aberration generator can be mounted. The cylindrical support is a 2 to 4 type generator. It is to be configured in various ways depending on the mounting form.

Algae power is generated by installing a water turbine with propeller on the seabed where the algae flows rapidly and then rotating the water generator by the force of the current. In particular, tidal power generation is an energy source that can be developed at any time regardless of climate change or season and is the only renewable energy source that can predict the amount of renewable energy. However, due to the complex technology of converting tidal energy, designing and constructing a structure, and applying and operating a power generation system, research has only recently started in advanced countries such as the US, Germany and Norway. South Korea also succeeded in installing the core structure of the world's largest test algae power plant in Uldulm, Jeonnam. The structure of the installed algae power plant consists of a huge structure weighing more than 1,000 tons, including the height of the upper house, reaching a height of 48m.

On the other hand, in the case of using algae, if the air density in the standard state (20 ℃, 1 atm, 75% relative humidity) is about 1.2, the density of water is about 830 times greater than the air density. Propellers have the advantage of being smaller in size. However, when using wind, the wind speed is usually around 10-20m / sec, while the speed of birds is about 2-5m / sec in Korea.

In addition, in the case of propellers using algae generally, the width of the blade is configured to be smaller than the wind power. There are various reasons, but there was a difficulty in constructing the structure of the propeller installed in the water, and in order to install such a large propeller, the structure installed in the water must also be enlarged. Therefore, difficulties due to the increase in the facility cost of the structure exist. There was no.

Moreover, in order to install such a large structure, it is necessary to install a foundation structure on the bottom of the sea or to form a large foundation structure made on the ground by dropping it on the bottom of the sea. There was a high concern that could adversely affect the marine environment ecosystem due to marine pollution.

On the other hand, if the algae propeller is large in size, even if the algae velocity is low, it is possible to obtain the effect that it is possible to secure a technology capable of rotating a generator which is converted at a high speed using an accelerator using a low speed propeller rotation. It has the advantage of being.

Therefore, it was necessary to develop a structure for tidal current generation, which can install a large propeller for large algae, while significantly lowering the cost of the structure.

In other words, if the depth from the water surface to the bottom of the sea is 40m and the difference between tidal currents is 6m, the algae can reach 34m and the braid length on one side of the propeller can be 15 meters or more. Will be.

In particular, the propeller can be enlarged, so that the contact area of the water flow can be greatly enlarged, so that even if the direction of the tide changes, even if the direction of the tide changes through the rotational speed of a similar propeller, a certain amount of power can be secured at all times. It became.

This effect can be equally applied to rivers or rivers in which water flow rates are generally formed quickly, and it can be understood as a technology that can solve a problem of difficulty in installing a structure in a region where the water flow speed is fast and deep.

The present invention will now be described in detail with reference to the accompanying drawings.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view illustrating a form in which a hollow casing 7 is inserted while forming an excavation hole 3 by using a drill 1 mounted on a barge 2. In order to determine the position of the excavation hole (3) for inserting and installing the first hollow casing (7), the bottom of the sea floor (6) so that the barge (2) can be fixed without shaking the barge (2) even in the flow of rapid tidal currents or streams of rivers. Or anchored to the bottom of the river (9) was to be fixed to the barge (2) by the chain (10). Of course, when installed on the sea is the direction of the bird is reversed, it is necessary to fix the anchor 9 and the chain 10 to the barge 2 in both directions.

Of course, in the case of rivers or rivers, a temporary work platform (not shown) may be installed instead of a barge (2), and a drilling machine (1) may be installed on the upper part thereof, and then the same may be operated. Should be included together.

When the position of the barge 2 is fixed by the anchor 3 and the chain 10 is installed by lowering the hollow casing (7) to the bottom of the seabed (6) using the drilling machine (1). At this time, the hollow casing (7) is generally used in the size of the nominal diameter 150A ~ 350A, and if necessary, can be equipped with a diameter of 1,000mm or more, and 6m length is the length of one pipe in the standard through welding work It is installed while connecting.

Zinc plating was applied to the inner and outer surfaces of the hollow casing 7 to prevent corrosion by salt components contained in seawater. Of course, a separate anticorrosion coating may also be implemented.

When the hollow casing (7) touches the sea bottom (6) and the installation is completed, the hollow casing (7) is fixed to the drilling machine (1), and then the excavation bit (4) for drilling the rock layer is hollowed using the rod (8). The casing (7) is lowered to the bottom of the seabed (6) and then the drilling machine (1) is operated to excavate.

At this time, the drilling machine (1) has a built-in compressor for producing high pressure compressed air, or a high pressure hose (not shown) is connected to a compressor (not shown) separately installed on the barge 2 to supply a large amount of compressed air produced at high pressure. I could receive it. As the excavation bit 4 is excavated deep into the rock line by the supply of compressed air and the operation of the drilling machine 1, the crushed rock powder is discharged to the outside through the inside of the hollow casing 7.

When the excavation hole 3 having a depth of 5 to 15 m is generally formed, the hollow casing 7 may be inserted into the excavation hole 3 by pressing the hollow casing 7 using the load of the drilling machine 1. have. At this time, the drilling device 1 and the hollow casing 7 are taken to be inserted in the vertical direction using a vertical level meter (not shown).

In the process of excavation using the drilling machine (1), and then inserting the hollow casing (7) into the pre-excavated excavation hole (3), the bottom of the sea (2) is formed of a hard rock without being made of a pearl layer, a compacted sand layer, or a weathered rock layer If it is, the insertion of the hollow casing 7 into the excavated excavation hole (3) itself may be difficult to proceed with the subsequent process. If there is such a concern, install a large diameter hollow casing (7) first, excavate with a large excavation bit (4), then raise the large excavation bit (4) again, and then install the small diameter hollow casing (7). Inserted into the excavated one-stage excavation hole (3) and to form a small diameter excavation hole (3) in two stages using a small diameter excavation bit (4).

The workbench 11 installed on the barge 2 has a fixing bracket 13 installed as shown in FIGS. 2 and 3, and a pinhole is installed on the barge 2 and the workbench 11 and fixed with a fixing pin 14. To make it possible. The worktable 11 has a recessed groove portion 17 so that the hollow casing 7 can be inserted therein, and a lower portion of the worktable 11 has a reinforcing table 16 and a pedestal 15 fixed to the barge 2. By enabling the reinforcement (11), there was no inconvenience for workers to proceed to work on the barge (2) and the work table (11).

When the subsequent processes such as the insertion and grouting of the hollow casing 7 are completed, the fixing pin 14 can be pulled out and the work table 11 can be separated, and the barge 2 can be separated and moved from the hollow casing 7. . Of course, the workbench 11 may be combined to separate or separate separate barges (not shown) that can be separated to obtain the same effect.

When the excavation is completed to the rock line to complete the excavation hole (3), as shown in Figure 5 on the barge (2), it is installed by inserting the reinforcement bundle 30 into the hollow casing (7) and the reinforcement bundle (30) The bottom of the to allow the bottom 20 of the excavation hole (3) can be reached.

The reinforcement bundle 30 coincides with the center of the hollow casing 7 and the center of the reinforcement bundle 30 during the insertion process so that the reinforcement bundle 30 is in the hollow casing 7 and the reinforcement bundle at any depth of the hollow casing 7. The outer side of the (30) was to be installed in the rebar bundle 30 at a certain distance so that the central disk 34 at all times to maintain a constant interval. The center disc 34 is made of tin plate or synthetic resin, and the reinforcing groove 33 and the trempipe groove 35 are configured to insert the reinforcing bar 30 as shown in FIG. 7 and the center reinforcing hole 36. Incision 39 was configured to insert the reinforcement bundle 30 in the center.

The fixing of the central disc 34 and the reinforcing bar bundle 30 can be conveniently and simply fixed by fixing using wires or the like.

On the other hand, unlike the inside of the hollow casing (7) in the process of inserting the reinforcement bundle 30 into the excavation hole (3), the excavation hole wall inside the excavation hole (3) is heavily formed or curved, or Some depressions may be formed so that the end of the reinforcement bundle 30 may be caught by such a portion, which may make it difficult to insert itself. In order to solve this problem, the tip cap 32 (see FIG. 5) was configured at the bottom of the rebar bundle 30. The tip cap 32 surrounds the rebar bundle 30 so that the tip portion is formed in a hemispherical shape of an ellipsoid so that insertion can be completed without a hang.

The tip cap 32 is to be made of casting or made of synthetic resin and to be made strong against impact. Collecting all the reinforcing bar 30 so that the end can be fixed to the answer cap 32, of course, the fixing method is a welding method or a screw, or a method of manufacturing by integrally gathering the whole reinforcing bar (30) molded into a single piece Can be used.

Of course, instead of the reinforcing bundle 30, a variety of structures, such as a file connected to the H-beams or flat iron that can fit inside the hollow casing (7) can be used, all of which will be referred to collectively as the reinforcing bundle (30) The parts may have a difference in degree, but a part configured to have a conical or hemispherical shape or the like by chamfering the corners so that there is no catching phenomenon when inserted is to be understood as the same configuration having the same purpose as the tip cap 32.

Inside the hollow casing (7) so that the grouting material that can make up the concrete such as ready-mix concrete from the bottom of the excavation hole 20, the tremi pipe 21 together with the reinforcing bundle (30) can be inserted and installed It was. Tremi pipe 21 is to be configured using a steel pipe pipe to secure the strength of the high-density polyethylene (PE) pipe or reinforced concrete.

Of course, in order to increase the convenience of work in the insertion process by connecting a rope (not shown) to the tip cap 32 or the rebar bundle 30, using a winding machine (not shown) installed on the barge 2 or While inserting it was also possible to adjust the insertion speed of the reinforcement bundle (30).

After inserting the hollow casing (7) and the excavation excavation of the excavation hole (3) to the rock line is completed, when the insertion of the reinforcing bundle (30) and tremi pipe (21) is completed, the mixed concrete, cement and mortar The grouting material is filled up from the bottom of the excavation hole 20 through the tremi pipe 21. In this case, the hollow pipe 7 is filled with sea water when working under the sea level 5, and fresh water is filled when the work is made at the bottom of the river or river.

The ready-mixed concrete or grouting material injected through the grouting pump (not shown) or the ready-mixed concrete truck (not shown) carried on the barge 2 is filled up from the bottom of the excavation hole 20 through the tremi pipe 21 and hollowed out. Sea water or fresh water that was initially filled in the excavation hole (3) and the hollow casing (7) while filling the casing (7) is pushed out to the outside through the hollow casing (7) to be discharged and the excavation hole (3) The interior and the inside of the hollow casing 7 is filled with a grouting material together with the reinforcing bundle 30 to be grouted 22 through the curing process to achieve strength.

In order to allow the injected grouting material to cure and cure in a short time, the hardening cement or quickening agent may be mixed and poured into the grouting material.

On the other hand, in the case of the cylindrical casing according to the flow of algae or water flow on the outer circumferential surface of the hollow casing (7), a flow resistance occurs in the front end and a vortex phenomenon occurs in the rear end, and as a result, it can affect the rotational force of the propeller of the water turbine generator. The wired rail portion 160 (see FIGS. 22 and 23) whose cross section is a streamlined or isosceles triangle is connected to the front and rear sides of the outer surface of the cylindrical support 70 to be described later from the top to the bottom. .

As shown in FIG. 6, when the grouting 22 is completed inside the hollow casing 7, the button-shaped cylindrical support 70 is completed. As such, when the rigid cylindrical support 70 is completed together with the hollow casing 7 as the reinforced concrete body by the reinforcement bundle 30 and the grouting 22 to the bottom of the rock bottom 6, the cylindrical support 70 itself is The barge (2) can be in charge of the function to be firmly fixed so that the position does not change even on a fast current or water stream.

The installation method of the structure for tidal current and water power generation, which allows the installation of a propeller and a generator to enable tidal power generation on the underwater floor according to the present invention,

(See Fig. 20) to make the cylindrical support 70 to be made in the process of installing so that the algae and the water flow structure for power generation can be completed.

As shown in Figure 11, the platform base 73 is usually installed to install a fixed bolt 74 to concrete to a certain standard using a jig plate (not shown) to fix the platform 81 and only the bolt head comes out Although it is configured, the overall shape may be regarded as referring to all components configured to cover the top of the cylindrical support 70 like a cap and to install a platform or a light by machining a female thread or welding.

The cylindrical support body 70 of the one-type configuration configured as described above can be configured by installing the cylindrical support 70 in two-part form at regular intervals or in a three-type or four-type form due to difficulty in installing a large-sized aquatic generator. It was. 14 shows an example of a three mold, FIG. 15 shows an example of a two mold, and FIG. 16 shows an example of a four mold.

It was to be made of a step of installing the aberration generator 61 between the cylindrical support 70 and the cylindrical support (70).

At this time, an expansion pipe 86 (see FIG. 12) is installed at an upper end of the third guide pipe 71c inserted into and inserted into the third hollow casing 71c through an underwater camera (not shown) in the barge 2. The third hollow casing 71c to be inserted and installed is accurately inserted into the third guide pipe 71c through the expansion part 86. As a result, the first, second, and third guide pipes 71a, 71b and 71c have the effect of being able to be inserted in the correct position by the gap support 72a, 72b.

Of course, even in this case, by mixing the hard cement or the fast curing material with the grouting material such as ready-mixed concrete, the process to greatly shorten the curing curing time can be divided into separate methods.

Further, the third and fourth hollow casings 7c and 7d are formed on the outer circumferences of the first and second hollow casings 7a and 7b of the cylindrical support 70 inserted and fixed to the sea bottom 6. The third and fourth guide pipes 71c and 71d for installation are connected to the first and second guide pipes 71a and 71b at regular intervals by the spacer holders 72a and 72b, respectively. A step of inserting and installing;

It was to be made of a step of installing the aberration generator 61 between the cylindrical support 70 and the cylindrical support (70).

Of course, even in this case, by mixing the hard cement or a fast cement with a grouting material such as ready-mixed concrete, it is possible to separate the processes to greatly reduce the curing curing time can be carried out in a separate method. The algae power generation structure composed of the four-cylindrical cylindrical support 70 configured as described above has various shapes such as rectangular or square, trapezoidal shape, and a separate coupling for mounting the aberration generator 61 for easy coupling and separation. Configure the device.

Of course, in case of constructing a tidal power generation complex by installing a continuous four-stage tidal current generating structure, a sufficient separation distance between the four-stage tidal power generating structure and the four-stage tidal current generating structure is considered in consideration of the width of the propeller 63 of the aberration generator 61. It can be installed with.

Through this method it is possible to form a continuous cylindrical support 70 as shown in Figures 14 to 16 it is possible to build a tidal power generation structure that can constitute a tidal power generation complex.

As another embodiment in which the cylindrical support 70 is installed using the barge 2 on which the drilling machine 1 is loaded,

The barge 2 is fixed at the position where the cylindrical support 70 is to be installed using the anchor 9 and the chain 10.

The barge 2 may be installed by arranging two drilling machines 1 in the opposite direction as shown in FIG. 8 or by turning a position on the barge ship 2 using a single drilling machine 1. At this time, the barge (2) width "A" was to be configured as the interval between the two columnar cylindrical support (70). When the two molds are continuously formed or composed of three or four molds, as shown in FIG. 9, the cylindrical support 70a is moved while maintaining a constant interval from the position of "I" to the position of "II". After fixing the barge 2 using the 70b, the drilling holes 3 are formed while inserting and installing the perforated casings 7c and 7d.

Of course, even in this case, by mixing the hard cement or the fast curing material with a grouting material such as ready-mixed concrete, the process that can greatly shorten the curing curing time can be divided into separate methods.

The tidal current generating structure including the two columnar cylindrical support member 70 configured as described above constitutes the first cylindrical support member 70a and the second cylindrical support member 70b in a horizontal direction formed in a direction perpendicular to the current direction as shown in FIG. It may also take the form of operating by mounting the aberration generator 61, and as shown in Figure 23 constitutes the first cylindrical support (70a) and the second cylindrical support (70b) in the direction of the column in the same direction as the tide direction In the meantime, it may take the form of operating by mounting the aberration generator 61.

In addition, the tidal current generator structure consisting of a four-cylindrical cylindrical support 70 takes the overall form of a rectangular or square, trapezoidal shape, etc., and a separate coupling for easy mounting and separation of the aberration generator 61 Configure the device.

Of course, in case of constructing a tidal power generation complex by installing a continuous four-tank tidal power generation structure, considering the width of the propeller 69 of the aberration generator 61, a sufficient separation distance between the four- tidal tidal power generation structure and the four-temporal tidal power generation structure is sufficient. It can be installed with.

Through this method it is possible to form a continuous cylindrical support 70 as shown in Figures 14 to 16 it is possible to build a tidal power generation structure that can constitute a tidal power generation complex.

For correct alignment of each cylindrical support body 70 formed, before and after the barge 2, the anchor 9 and the chain 10 are installed to release or pull the chain, and at regular intervals and distance in the form of a checkerboard Installation of the support 70 was made.

As shown in Figure 18 and 19, the upper end of the cylindrical support 70 is coupled to the reinforcement 80 to both sides in the form of a Y-shaped and the same height as the top surface of the platform base 73, the platform base 73b, 73c, respectively To be formed to raise the pratt groove 81 on the top to be fixed using a fixing bolt 74 and the nut 82. The platform 81 is provided with a cover plate 83 between the surfaces fixed to the upper portion of the cylindrical support 70, respectively, so as not to obstruct the lifting of the aberration generator 61 or the propeller 69.

In order to prevent disturbance of rotation of the propeller 69 by disturbing the flow of algae according to the size of the guide pipe 71, the fixed pipe 76, and the aberration generator 61 installed in the cylindrical support 70. They can be located inside the inner rotating surface of the blade. That is, the connecting rod 88 is formed in the portion occupied by the aberration generator body so as not to be affected by the algae flow.

The aberration generator 61 is installed in the form of a housing in which an accelerator gear (not shown) and a generator (not shown) are built therein, and generally takes the form of a general tidal current generator.

As shown in FIG. 20, the lifting ring 64 and the chain or rope 62 are installed to lift or install the aberration generator 61 above the aberration generator 61. The aberration generator 61 is to fix the generator support 67 to the second sliding ring (65b) configured to slide through the cylindrical support (70) and to fix the aberration generator (61) there. In order to withstand the load of the aberration generator 61, the generator support 67 was used to support the aberration generator 61 by using a support bracket 68.

The shaft 63 withdrawn from the aberration generator 61 is generally applied with a mechanical seal (not shown) to prevent leakage, and the propeller 69 is fixed to the front end of the shaft 63. The propeller 69 is configured to have the same braid angle on the front and rear sides so that the propeller 69 rotational force can be obtained even if the flow direction is formed in either the front or the rear direction.

The first sliding ring 65a is inserted into the cylindrical support 70 on the side opposite to the cylindrical support 70 on which the aberration generator 61 is fixed, and is slidably installed, and has the same axis center as the shaft 63. The sleeve housing 56 is fixedly installed at the position.

A shock absorbing spring 58 is installed inside the sleeve housing 56, and a piston part 55 is formed therein. The piston unit 55 is assembled so that the propeller shaft 54 is fixed to the bearing 52 and rotated while being inserted into the sleeve housing 56 while pressing the shock absorbing spring 58. In order to help prevent displacement of the shaft in this connection process, the first sliding ring (65a) was configured to support the load by configuring the support bracket 140 at the bottom.

The piston part 55 processes the key groove 91 in the upper and lower positions to prevent the accompanying rotation according to the rotational force of the propeller shaft 54 and inserts the sleeve key 92 in the sleeve housing 56 by inserting it. It was made.

The structure in which the shock absorbing spring 58 is installed in the sleeve housing 56 generally has an internal shape similar to that of a spring shock absorber (not shown), and when the cylindrical support 70 is composed of two to four cylinders, The first and second sliding rings 65a and 65b have elasticity even when the distance between the supports 70 is out of the tolerance range so that the up and down driving is performed on the cylindrical support 70 so that there is no obstacle.

Of course, the cylindrical support 70 is immersed in sea water for a long time and various methods and devices for removing it to solve the difficulties caused by corrosion or the closing of the driving area due to the growth and growth of seaweeds, mussels, oysters and seabed habitats However, the first and second sliding rings 65a and 65b may be provided with removal blades (not shown) on the outer peripheries of the upper and lower sides, respectively, so that these reproductive organisms are naturally removed during vertical movement. It can also be turned off.

As another method, the sleeve housing 56 having two shafts having the guide rails 111 installed on the outer circumference of the cylindrical support 70 and attached with rollers 112a and 112b rotated on both sides of the guide rails 111 is provided. To construct. Of course, the roller (112a), 112b (top) and the bottom of the blade (not shown) that can remove the living organisms is effective to attach and operate.

As another method, as shown in Figs. 26 and 27, the cylindrical support 70 is inwardly recessed 166 so as to surround and rotate the outer diameter of the cylindrical support 70 inwardly in which the aberration generator 61 is installed. By installing a roller 163 having a configuration to be able to drive up and down.

The roller 163 is supported by the rotating shaft 171 installed on the frame 170, and one axis of the frame 170 is a propeller shaft 54 installed on the generator support 67 or the opposite side of the aberration generator 61. Is supported by the bearing 52.

Naturally, such a vertical drive structure can be applied to the cylindrical support body 70 supporting the aberration generator 61 and can be operated in the same manner.

As an example of constructing a water wheel generator provided with a water wheel type propeller of a watermill type,

As shown in FIG. 17, FIG. 24, and FIG. 25, the cylindrical support body 70 is comprised by three-type or four-type.

Between the cylindrical support 70, the blade-shaped propeller 130 is extended to the shaft 136 to both sides to be coupled to the subsidiary body 131. The one side spherical body (131a) is a shaft bearing (not shown) is built so that the blade-shaped propeller 130 is prevented when rotating, the gear box 133 and the aberration generator (61) inside the opposing side spherical body (131b) Will be built in. Of course, the aberration generator 131 is installed on the top of the aberration generator and gear transmission, the type of propulsion by transmitting the rotational force of the blade-type propeller 130 using a belt pulley is also included in the meaning of the aberration generator 61 Should be considered.

On the other hand, on the outer periphery of the cylindrical support body 70 in contact with the subsidiary body 131, a sliding pipe body 135 is installed to enable vertical driving. The hemispherical cover portion 138 is configured on the upper portions of the spherical bodies 131a and 131b so as to cover the upper portion of the blade-shaped floppler 130 in order to prevent rotation disturbance due to sea wind or waves or rain.

In the present invention configured as described above, even if fluctuations in the sea level 5 due to the difference between tides occur, one wing of the propeller-type propeller 130 is always locked to the direction of the tidal flow at a constant depth so that the rotational force of the aberration generator 61 is maintained. It can be secured.

Of course, the outline of the up and down drive device can be applied to a variety of methods as in Example 2 described above.

In addition, the propeller 69 coupled to the aberration generator 61 in the various embodiments is not only a general propeller having a blade, but also any type of tidal current or water flow such as a transverse horizontal axis water turbine which is developed and applied. It should be considered as a generic term for a form that can be rotated by.

In addition, as in the blade propeller 130, the aberration generator 61 and the propeller 69 are not integrally coupled, but a separate gearbox 133 is configured and various power transmissions such as a drive chain, a rope, and a V belt are performed. It should be understood that the rotational force of the propellers 69 through the device collectively refers to all structures capable of rotating the aberration generator. That is, the aberration generator 61 may be configured to install a wheel (not shown) on the propeller 69 installed in the water and to drive a generator (not shown) installed on the platform 81 using a drive chain. .

In addition, the aberration generator 61 is provided with a brake (not shown) to stop the operation of the propeller 69 until a constant flow rate is formed in order to solve the rotational instability of the propeller 69 during conditioning. The brake can be applied to a method of forcibly pressing the brake pad to the disc-shaped wheel or operating it by using an electromagnet like a normal automobile brake.

On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And, it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood as
