Description

Vibration-type generator installed on an exterior wall

The following embodiments relate to a vibration generator installed on an outer wall.

In a large city where high-rise buildings are dense, when the wind blows against the buildings, a very strong wind blows between the buildings. Or, the wind blowing from above hits a high-rise building and descends directly to the ground. This wind is called building wind or building wind. In Korea, this phenomenon is particularly confirmed in Seoul, where high-rise buildings such as banks, department stores, and hotels are concentrated. Such building winds cause unexpected gusts of wind on the ground, causing inconvenience to life.

Various methods exist as countermeasures to reduce such damage from the building style. First, there are cases in which designs are designed to minimize the building style from the building layout planning stage. For example, the NFC Super Tower building in Japan has all three floors in the middle of the building as wind bleeds to guide the descending strong wind in this direction. However, this method can be applied in the planning stage of a building, but there are difficulties in applying it to an already built building.

In addition, it is possible to obtain an effect of weakening the building wind while generating power by installing a wind power generator using the building wind in a building. However, when the wind power generator is installed in a building, there is a problem in that the appearance is not good and noise is generated.

On the other hand, in the case of a vibration-type eco-friendly generator using a fluid disclosed in Republic of Korea Patent Publication No. 10-1806312 (2017.12.01), it has an easy structure for miniaturization and has installation flexibility that can be efficiently placed in any space, By using a simple vibration-type power generation method, the resistance area with the fluid is small, the durability of the product is high, and the production cost is low, so it has advantages suitable for the power generation method using the building style described above.

However, there is a need for a solution to obtain the power generation effect and the weakening of the building wind without reducing the appearance of the already built building as much as possible. Therefore, there is a need to develop a vibration-type generator that can be installed in a building while having high power generation efficiency.

In particular, in a residential area where apartments or high-rise officetels are densely populated, the wind load due to the building wind is significant.

With reference to the drawings, the vibration generator 1 installed on the outer wall will be described.

Referring to Figure 1, the vibration generator 1 installed on the outer wall, the inlet (2b) and the outlet (2c) are formed, the tunnel (2a) through which the fluid flows is formed in the block 2 and the block (2) It is configured to include a power generation unit 10 that is generated by the fluid flowing inside the tunnel (2a). Here, the inlet (2b) and the outlet (2c) are divided for convenience of description, and according to the flow of the fluid, the fluid may be introduced into the outlet (2c) and the fluid may be discharged through the inlet (2b).

The block (2) is formed integrally with the outer wall of the building or formed as a separate entity from the outer wall of the building to be attached to the outer wall.

For example, as shown in FIGS. 1 to 2B , the block 2 may be formed by directly constructing the tunnels 2a, 3a, and 4a on the outer wall of the building.

As shown in FIG. 1 , an inlet 2b and an outlet 2c may be formed by constructing a tunnel 2a to penetrate an outer wall orthogonal to each other such as a corner in a building. Alternatively, as shown in FIG. 2A , the inlet 3b and the outlet 3c may be formed by constructing the tunnel 3a to penetrate the surfaces opposite to each other in the building. Alternatively, as shown in FIG. 2b , the tunnel 4a may be constructed so that both the inlet 4b and the outlet 4c are located on one surface of the building.

In addition, the shape of the tunnels 2a, 3a, and 4a is not limited by the drawings, and may be formed in substantially various shapes.

On the other hand, the block 5 may be formed as a separate entity from the outer wall of the building. Referring to FIG. 3 , a tunnel 5a is formed in the block 5 formed as a separate entity from the outer wall of the building. In this case, the block 5 formed as a separate entity protrudes from the outer wall of the building, thereby preventing the fluid flowing along the outer wall of the building from flowing in the inner direction of the tunnel 5a and passing through the inlet 5b, and allowing the fluid to pass through the tunnel. It can be introduced into (5a) to flow toward the outlet (5c). The block 5 formed as a separate entity is not limited to the shape of the drawing and can be substantially changed in various ways in consideration of the surrounding environment. Here, the block 5 formed as a separate entity may be installed on the exterior wall of the building, or may be formed integrally with the exterior wall of the building to protrude from the exterior wall of the building.

The housing 90 may be formed so as to be insertable into the tunnels 2a, 3a, 4a, 5a of the blocks 2, 3, 4, 5. Referring to Figure 4, the housing 90 is formed in a shape that can be inserted into the tunnel (2a, 3a, 4a, 5a) of the block (2, 3, 4, 5), the block (2, 3, 4, 5) ) of the tunnel (2a, 3a, 4a, 5a) is formed to enable insertion and separation.

The housing 90 has a housing inlet 90a and a housing outlet 90b formed therein, a power generation unit 10 is installed therein, and a contact type electric circuit terminal 91 for supplying power to the power generation unit 10 . is provided The contact-type electrical circuit terminal 91 is formed in a portion in which the housing 90 and the inner surfaces of the tunnels 2a, 3a, 4a, and 5a are in contact, and is provided to transmit power generated from the power generation unit 10 to the outside. do. Alternatively, a configuration in which the contact type electric circuit terminal 91 is omitted is also possible.

According to the present embodiment, since the power generation unit 10 is installed inside the housing 90 , when maintenance of the power generation unit 10 is required, the housing 90 can be separated, so maintenance is convenient. The shape of the housing 90 is not limited to the drawings, and may be substantially variously changed in consideration of the surrounding environment.

Power generation unit 10 is a fluid flowing inside the tunnels (2a, 3a, 4a, 5a) of the blocks (2, 3, 4, 5) and blocks (2, 3, 4, 5) in which the tunnels in which the fluid flows are formed. It is a vibration-type generator that generates electricity using

Referring to FIG. 5 , the power generation unit 10 includes a fixed panel 110 , a magnetic body 120 , a motion panel 130 , a power generation loop 140 , and a rotation shaft 150 . Here, the magnetic body 120 is provided on the fixed panel 110 or the exercise panel 130 , and the power generation loop 140 is provided at a position corresponding to the magnetic body 120 . For example, as shown in FIG. 5 , when the magnetic material 120 is provided on the fixed panel 110 , the power generation loop 140 is provided on the exercise panel 130 spaced apart from the fixed panel 110 by a predetermined interval. Conversely, a form in which the magnetic body 120 is provided on the exercise panel 130 and the power generation loop 140 is provided on the fixed panel 110 is also possible. In the following description, the magnetic body 120 is provided on the fixed panel 110 and the power generation loop 140 is provided on the exercise panel 130 based on the description, and the opposite case will be omitted.

Referring to FIG. 6 , the exercise panel 130 includes a power generation loop 140 , a power generation coil 141 , a rotation shaft 150 , a communication hole 151 , a rotation groove 152 and an elastic member 160 in more detail. is comprised of

The fixed panel 110 and the exercise panel 130 are spaced apart from each other by a predetermined distance. For example, at least one fixing panel 110 is provided, and is spaced apart from the exercise panel 130 by a predetermined distance and disposed to face each other. For example, the fixed panel 110 may be provided as one and may be disposed to be spaced apart from the exercise panel 130 by a predetermined distance. The distance between the fixed panel 110 and the exercise panel 130 may be arranged to be parallel to each other in terms of high power generation performance in consideration of the magnetic flux density between the magnetic body 120 and the power generation loop 140 to be described later.

The fixing panel 110 is preferably formed of a rigid material so that the position of the magnetic body 120 does not change due to the influence of wind. However, this is only an example, and it is also possible for the fixing panel 110 to be formed of an elastic material.

At least one magnetic body 120 is provided on the fixing panel 110 . For example, as shown in FIG. 6 , the magnetic body 120 is inserted and disposed on the side surface of the fixing panel 110 .

The magnetic body 120 may be provided to protrude to the outside of the fixed panel 110, but if the magnetic body 120 is provided to protrude, it is possible to limit the rotation angle of the exercise panel 130 to be described later, so that the fixed panel ( 110) is preferably inserted into the inside. However, this is only an example, and the magnetic body 120 forms a predetermined interval in a row or a plurality of columns in the longitudinal direction of the fixing panel 110 , and a plurality of magnetic bodies 120 may be provided.

The magnetic body 120 may be any means having magnetism. For example, the magnetic body 120 may be a permanent magnet or an electromagnet. It is preferable that the magnetic body 120 is a permanent magnet, which can simplify the design and does not require a separate power to be applied. When the magnetic material 120 is provided as an electromagnet, power must be applied to the fixed panel 110 , so that the structure of the fixed panel 110 may be complicated and power consumption may occur.

The power generation loop 140 is provided on the exercise panel 130 , and is provided at a position corresponding to the magnetic body 120 of the fixed panel 110 . Here, the meaning that the power generation loop 140 and the magnetic body 120 correspond means that when the movement panel 130 rotates, the magnetic flux lines of the magnetic body 120 face each other so that the power generation loop 140 can enter the inside. .

The power generation loop 140 has a closed curve shape formed by winding the power generation coil 141 . The power generation loop 140 includes a negative power generation terminal 141a and a positive power generation terminal 141b which are formed by withdrawing the power generation coil 141 from a starting point and an end point of the power generation loop 140, respectively.

The negative power generation terminal 141a and the positive power generation terminal 141b are connected to a power generation circuit (not shown) to convert the AC current generated by the power generation unit 10 into a DC current to be connected to an electronic device such as a battery to supply current. have. In addition, the power generation unit 10 is directly connected to the electronic device without converting the AC current to the DC current, it is also possible to supply the AC current.

The rotation shaft 150 has an outer peripheral surface of one side opened to form a communication hole 151 communicating the inner space of the rotation shaft 150 . For example, the rotary shaft 150 has a communication hole 151 formed therein, so that the power generation coil 141 , that is, the negative power generation terminal 141a and the positive power generation terminal 141b is connected to the rotary shaft 150 through the communication hole 151 . It may be drawn out to one end of the rotation shaft 150 through the outer circumferential surface of the or may be drawn out to both ends, respectively. The communication hole 151 may be opened in a sectoral shape so that the power generation coil 141 may rotate together when the movement panel 130 rotates. Through the communication hole 151 , the power generation coil 141 does not undergo plastic deformation due to rotation in the rotation shaft 150 portion, so that the lifespan of the power generation unit 10 can be increased.

The rotation shaft 150 may be formed with a rotation groove 152 . For example, the outer peripheral surface of the rotation shaft 150 may be formed with a rotation groove 152 concavely formed to have an inner diameter smaller than the outer diameter of the rotation shaft 150 .

A protrusion 132 may be formed on the inner peripheral surface of the rotation hole 131 to have a smaller diameter than the inner diameter of the rotation hole 131 . The protrusion 132 is disposed to be inserted into the rotation groove 152 . For example, the outer diameter of the rotation shaft 150 has a smaller diameter than the inner diameter of the rotation hole 131 , and when the rotation shaft 150 is disposed in the rotation hole 131 , the protrusion 132 is formed in the rotation groove 152 . By being placed in contact with the rotation shaft 150 and the rotation hole 131, only a portion of the contact can reduce the frictional force. A lubricant is applied to the contact surface of the rotating groove 152 and the protrusion 132 to reduce frictional force.

However, this is only an example, and it may be possible that the rotation groove 152 is formed in the rotation hole 131 and the protrusion 132 is formed in the rotation shaft 150 . Meanwhile, at least one elastic member 160 is disposed in a space spaced apart from the rotation shaft 150 and the rotation hole 131 to connect the rotation shaft 150 and the rotation hole 131 to each other. For example, the rotation shaft 150 is connected to the rotation hole 131 by at least one or more elastic members 160 provided in the rotation hole.

The elastic member 160 may have a restoring force, and when the movement panel 130 is rotated about the rotation shaft 150, it may be a spring, rubber, etc. that is tensioned or compressed and then restored to its original shape. When the exercise panel 130 rotates in one direction, the elastic member 160 may increase vibration efficiency by applying a restoring force that rotates it in the other direction. In other words, the elastic member 160 may increase the vibration efficiency of the exercise panel 130 by applying a restoring force to the exercise panel 130 rotated at a predetermined angle to rotate in the opposite direction. In addition, during rotation, it may be possible to apply an appropriate restoring force so that the movement panel 130 does not touch the fixed panel 110 .

The fixed panel 110 and the exercise panel 130 may be freely arranged, but the movement panel 130 is arranged to secure a rotational space. In other words, the distance between each fixed panel 110 and the exercise panel 130 may be appropriately changed according to the rotation angle of the exercise panel 130 .

The fixing panel 110 may have a flat plate shape. The fixing panel 110 may be provided in the form of a bulkhead by being fixed to an installation place.

Referring to FIG. 7A , the fixing panel 110 is fixedly installed inside the tunnel 2a, and a plurality of fixing panels 110 are arranged in parallel to the wall surface of the tunnel 2a along a row. In addition, the plurality of fixing panels 110 may be arranged in one row or in two or more rows inside the tunnel 2a.

Here, the magnetic material 120 is provided on the wall surface of the tunnel 2a as well at a position opposite to the power generation loop 140 of the exercise panel 130, so that the wall surface of the tunnel 2a can serve as the fixed panel 110. have.

Alternatively, the fixing panel 110 may be installed not parallel to the wall surface of the tunnel 2a. For example, as shown in FIGS. 7B to 7C , the fixing panels 111 and 112 may be inclined to have a predetermined angle with respect to the wall surface of the tunnel 2a. In addition, as shown in FIG. 7B, all of the fixing panels 111 are installed to be spaced apart from the wall, or as shown in FIG. 7C, some of the fixing panels 112 are spaced apart from the wall, and some are connected to the wall. It may be installed as much as possible. However, this is only an example, and the fixing panels 111 and 112 may be arranged in various shapes to control the flow of fluid and increase power generation efficiency.

Also, referring to FIG. 7D , a groove 2d into which the rotation shaft 150 of the exercise panel 130 is inserted is formed in the tunnel 2a. The groove (2d) is formed in the floor and ceiling of the tunnel (2a), the rotation shaft 150 is formed with a diameter of a size that can be inserted. In addition, the rotation shaft 150 is configured to be extendable in the axial direction, and can be fixed to the groove 2d by increasing the length in the axial direction when the movement panel 130 is to be arranged in a plurality of layers. By providing the groove 2d, when a failure occurs in the movement panel 130, the rotation shaft 150 may be removed to repair or replace the movement panel 130.

Meanwhile, a piezoelectric element (not shown) and a thermoelectric element (not shown) may be provided inside the fixed panel 110 and the tunnel 2a. The piezoelectric element converts impact energy generated when a fluid contacts the wall surface of the fixed panel 110 and the tunnel 2a into electrical energy to enable power generation, either one or both sides of the wall surface of the fixed panel 110 and the tunnel 2a. can be provided in In addition, the thermoelectric element may generate an electromotive force due to a temperature difference between the fixed panel 110 and the fluid in contact with the inner surface of the tunnel 2a.

Referring to FIG. 8 , the power generation unit 10 may include a plurality of fixed panels 110 and a plurality of movement panels 130 . The fixed panel 110 and the exercise panel 130 may be alternately disposed at the same interval or at various different intervals. Also, the plurality of fixing panels 110 and the movement panels 130 may be disposed along a plurality of columns. Here, the plurality of fixed panels 110 and the plurality of movement panels 130 may be disposed on the same straight line along one row or disposed to be shifted from each other. In addition, the plurality of fixed panels 110 and the plurality of movement panels 130 may be arranged in a plurality of layers in the vertical direction.

According to the present embodiment, it is possible to increase the amount of power generation by arranging the plurality of fixed panels 110 and the plurality of motion panels 130 in a plurality of rows and a plurality of layers.

Alternatively, referring to FIG. 9 , as illustrated in FIG. 4 , the power generation unit 10 is installed inside the housing 90 , and a plurality of fixed panels 110 and a plurality of motion panels 130 may be installed. have. In addition, a vibration absorbing member 920 may be further provided between the housing 90 and the tunnel 2a.

The vibration absorbing member 920 is formed of an elastic material to prevent vibration from being transmitted. The vibration absorbing member 920 is disposed around the outer surface of the housing 90, for example, is disposed on the bottom.

Alternatively, the vibration absorbing member 920 may be disposed not only on the bottom surface of the housing 90 , but also on the periphery of other surfaces other than the surface corresponding to the inlet 2b and the outlet 2c of the tunnel 2a.

Referring to FIG. 10 , the blocks 2 , 3 , 4 , and 5 may be provided with a fluid guide plate 20 for guiding the fluid to the inlet around the inlet.

The fluid guide plate 20 is formed to protrude from the inlet (2b, 3b, 4b, 5b) at a predetermined distance from the periphery. For example, the fluid guide plate 20 has a flange shape having a predetermined height, is formed in a portion along the circumference of the inlets 2b, 3b, 4b, 5b, and the fluid flows through the inlets 2b, 3b, 4b, 5b. A part has an open shape so that it can flow to the The fluid guide plate 20 serves to guide the fluid flowing near the wall surfaces of the inlets 2b, 3b, 4b, and 5b to flow into the inlets 2b, 3b, 4b, and 5b.

In addition, although not shown in the drawings, a piezoelectric element (not shown) may be provided on the surface of the fluid guide plate 20 . The piezoelectric element can generate electricity by converting the impact energy generated when the fluid contacts the surface of the fluid guide plate 20 into electrical energy. The piezoelectric element can be any means capable of generating electricity by impact, such as a piezoelectric material and a capacitor capable of simulating the piezoelectric effect.

The shape of the fluid guide plate 20 is not limited to the drawings, and it can be installed by changing the fluid flow environment in consideration of the fluid flow environment.

In addition, the fluid guide plate 20 may serve as the fluid guide plate 20 by utilizing a protruding portion of the outer wall of the building rather than an entity formed separately from the outer wall of the building.

In addition, the inlet (2b, 3b, 4b, 5b) may be provided with a sieve 30 for preventing the inflow of contaminants. The sieve 30 is installed at the inlets 2b, 3b, 4b, and 5b to block foreign substances contained in the fluid from flowing into the tunnels 2a, 3a, 4a, 5a, thereby reducing power generation efficiency due to the inflow of foreign substances and failure of the power generation unit 10 can be prevented.

A mechanism for reducing the energy of the fluid through the vibration generator 1 installed on the outer wall will be described with reference to FIGS. 11A and 11B .

Referring to FIG. 11A , a tunnel 2a is formed in a vertical direction in the block 2 protruding from the outer wall of the building. The tunnel 2a descends in a vertical direction from the inlet 2b and is curved toward the outer wall of the building to form an outlet 2c. A plurality of fixing panels 110 are installed inside the tunnel 2a. A movement panel 130 is disposed between the fixed panels 110 . In this case, the positions of the fixed panel 110 and the exercise panel 130 may be arranged at a position with high power generation efficiency according to the flow of the fluid. A downdraft (F ₁ ) is formed on the outer wall of the building formed in this way, and the downdraft (F ₁ ) is dispersed into an air flow (F ₂ ) flowing into the tunnel and an air flow (F ₃ ) flowing along the outer wall without entering the tunnel. . The airflow F ₂ introduced into the tunnel is reduced in energy while passing through the vibration generator installed inside the tunnel, and the weakened airflow F ₂₁ flows out to the outlet 2c of the tunnel. The weakened airflow (F ₂₁ ) does not enter the tunnel and forms a vortex (F ₄ ) while meeting the airflow (F ₃ ) flowing along the outer wall. As such, the downdraft F ₁ is dispersed in two by the tunnel 2a, the energy is reduced by the power generation unit 10, and the vortex F ₄ is formed as the first downdraft F ₁ The energy of ) is weakened, and damage caused by the downdraft (F ₁ ) can be prevented.

Here, not only the downdraft but also the updraft may have an effect of weakening energy through the above-described process.

Referring to FIG. 11B , a tunnel 2a is formed to pass through the outer walls orthogonal to each other, such as the corners of the outer wall of the building. 11A , a plurality of fixed panels 110 and movement panels 130 are disposed inside the tunnel 2a. The fluid that collides with the outer wall of the building flows along the outer wall of the building to form a separation airflow (F ₅ ), and takes the form of winding around the outer wall of the building. The separation air flow F ₅ is dispersed into an air flow F ₆ introduced into the tunnel and an air flow F ₇ flowing along the outer wall without entering the tunnel, as in FIG. 11A . In addition, the energy of the airflow F ₆ introduced into the tunnel is reduced while passing through the vibration generator installed inside the tunnel, and the weakened airflow F ₆₁ flows out to the outlet 2c of the tunnel. The weakened airflow (F ₆₁ ) does not enter the tunnel and forms a vortex (F ₈ ) while meeting the airflow (F ₇ ) flowing along the outer wall. In this way, the separation air flow F ₅ is divided into two by the tunnel 2a, the energy is reduced by the power generation unit 10, and the vortex F ₈ is formed as the first separation air flow F ₅ The energy of ) is weakened, and damage caused by the separation airflow (F ₅ ) can be prevented.

Here, even when the direction of the wind is opposite, it may have an effect of weakening the energy through the above-described process.

According to the present embodiments, the vibration-type generator 1 installed on the outer wall has a simple structure with the minimum configuration required for power generation, and is easy to miniaturize, so it can be flexibly installed without restrictions on the shape and place of space.

In addition, the vibration generator 1 installed on the outer wall is installed in a structure optimized to reduce the wind pressure of the building wind, so that damage caused by the building wind which occurs frequently in the city center can be reduced.

In addition, the vibration generator 1 installed on the outer wall can additionally obtain an eco-friendly power generation effect by converting the wind energy of the building wind into electric energy.

In addition, the vibration-type generator 1 installed on the outer wall has a simple power generation method, so the critical wind speed and flow speed for generator operation are relatively low, so electricity can be produced even with a small flow of fluid, and electricity production is possible without malfunction even at a high flow rate. It is possible.
