Description

In-phase power generation system {GENERATOR SYSTEM ON ROAD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation system that generates power using the mechanical energy of a traveling vehicle.

Speed bumps are installed on the road to secure vehicle driving safety or to protect pedestrians for various purposes.

In general, the purpose of installing the speed bumps is to prevent the speeding of vehicles by installing them in residential or child protection areas to prevent noise and human accidents caused by speeding vehicles. In addition, ascon is stacked on slopes, downhills, and hills, which are points of accidents, and speed bumps are installed to effectively reduce vehicle speed.

If the speed bump is installed on the road, in order to pass the speed bump, the vehicle must perform deceleration and operation, which causes waste of energy. However, since the safety effect and the pedestrian protection effect according to the overspeed prevention of the vehicle have priority over the energy saving, installation of the overspeed bumps is inevitable.

On the other hand, since the weight of the vehicle passing through the speed bumps is considerable, when power generation is performed using the speed bumps, it is possible to recover a considerable amount of energy wasted due to the presence of the speed bumps.

Accordingly, the invention as described in the Korean Utility Model Publication No. 1993-3686 and the Korean Patent Publication No. 2004-0051448 has been proposed several times in order to perform power generation using the speed bumps.

However, the inventions proposed to date do not overcome the following problems.

The first problem is an increase in the manufacturing cost of the speed bumps due to the complicated structure.

The second problem is that as the mechanical energy by the vehicle is applied intermittently, the power generation efficiency is lowered.

The third problem is that the energy used for power generation is smaller than other commercial power generation devices, and the power generation efficiency is lowered.

The last problem is that, in the case of the proposal in which the speed bumps to generate power are buried in the road, the lower part of the road must be dug, so installation and maintenance are difficult.

The present invention devised to solve the above problems, an object of the present invention is to provide an overspeed bump-type phase-generating power generation system with low manufacturing cost.

In addition, another object of the present invention is to provide an overspeed bump-type phase-generating power generation system capable of increasing power generation efficiency.

In addition, another object of the present invention is to provide an overspeed bump-type phase-generating power generation system that is easy to install and release.

In accordance with an aspect of the present invention, a power generation system according to an aspect of the present invention includes a direction switching elastic body that converts a force in a vertical direction by a weight of a vehicle into a horizontal force and provides a restoring force of a speed bump; An air compression unit for compressing air by using a horizontal force of the direction change elastic body; An air tank for accumulating air pressure; An air pressure injection unit for injecting air pressure by air compressed by the air compression unit into the air tank; And a generator for generating electricity by driving with the air pressure accumulated in the air tank.

By implementing the in-phase power generation system of the present invention according to the above configuration, it is possible to reduce the manufacturing cost of the speed bump-type in-phase power generation system, and to advance the practical use.

Or the island-based power generation system of this invention has the advantage which can raise power generation efficiency.

Or the island-based power generation system of this invention has the advantage that it is easy to install and remove.

Vehicles passing through the speed bumps apply a force in the direction of gravity to the speed bumps, and the in-phase power generation system according to the spirit of the present invention intends to perform power generation using the force in the direction of gravity.

By the way, since the mechanical structure that receives the force in the gravity direction as it is, should have a sufficient magnitude in the downward direction, the present invention proposes a structure for converting the force in the gravity direction in a direction parallel to the road. Here, the direction parallel to the road is preferably a direction perpendicular to the vehicle traveling direction, in order to transmit the force in the direction that the vehicle does not travel.

On the other hand, the speed bumps constituting the vehicle energy receiving device of the in-vehicle power generation system according to the spirit of the present invention needs a structure that is deformed by the gravity of the vehicle and gives an elastic force to restore to the original state when the vehicle passes.

If both the structure for changing the direction of the force and the elastic force provision structure is provided, it is obvious that the manufacturing cost of the speed bumps is greatly increased, which will be a major obstacle to practical use.

The present invention proposes a structure for inexpensively implementing the structure for changing the direction of the force and the elastic force applying structure as a single structure.

1A and 1B illustrate one embodiment of a reversible elastomer that can be used in the in-phase power generation system of the present invention.

The illustrated reversible elastic body 1001 cuts a predetermined area of a rectangular plate made of an elastic material into parallel horizontal lines, and then bends the belt-shaped structure formed according to the cut in a manner of alternating up and down directions. It is a kind of leaf spring. That is, it is a corrugated leaf spring having a plurality of arcuate structures 1101 and 1201 in the vertical direction of the leaf spring. Although the illustrated 1101 and 1201 structures are close to triangles, the semicircle, triangle, and sinusoidal shapes will be collectively referred to as arches.

The reversible elastic body 1001 receives a force applied in an up-down direction PV to the center point PP of each of the arcuate structures of the plurality of arcuate structures 1101 and 1201.

In the illustrated direction change elastic body 1001, when a force is applied in the PV direction, the length is extended in the PH direction, and when the force applied in the PV direction is removed, the portion extended in the PH direction by its own elasticity is original. Return to position

More specifically, the direction change elastic body 1001 in which one end HA is fixed converts the PV direction force into a force in the PH direction, and when it is not fixed, the direction change elastic body 1001 converts the PV direction force into PD1. And forces in the PD2 direction.

As illustrated, when the wheel of the vehicle is located on the upper surface of the speed bump, the speed bump is flatly deformed by the weight of the vehicle. In the deformation, the upper surface of the speed bumps is moved downward, thereby compressing the direction change elastic body in the speed bumps downward, and the center rod connected to the direction change elastic body protrudes outward from the road. The protruding center rod may transfer mechanical energy to the outside of the speed bump.

As the vehicle moves, when the wheel of the vehicle located on the upper surface of the speed bump is removed, the center rod is restored to the original shape of the speed bump, which is flatly deformed by the elastic force of the reversing elastic body, and protrudes to the outside. Returns to its original position.

As a result, each time the vehicle passes the upper surface of the speed bump, the center rod is reciprocated.

2A and 2B show another embodiment of the reversible elastic body that can be used in the in-phase power generation system of the present invention.

The illustrated turning elastic body 1002 cuts a predetermined area of a rectangular plate made of an elastic material into parallel horizontal lines, and then overlaps the structure 1102 that bends upwards a band-shaped structure formed according to the cutting. (1702, 1802) is a kind of leaf spring alternately implemented. That is, a corrugated leaf spring having a plurality of upward arcuate structures.

There is a difference. The bearing is generally located on the contact surface with the inner shaft of the roller 1403.

By the roller 1403 and the bearing, the friction between the direction switching elastic body 1003 and the case of the speed bumps therein can be reduced.

One end HA of the reversible elastic body 1005 is fixed, and the other end thereof may be provided with an air pump or a center rod 1505 for driving the power transmission means.

Since the connecting structure of the cover plate 2405 and the lower plate 2205 of the speed bumps 2005 shown in FIG. 7A is similar to that of FIG. 7A, detailed description thereof will be omitted.

In the illustrated speed bumps 2005, a direction change elastic body 1004 is mounted to extend in the driving direction of the vehicle. As a result, the force applied in the up and down direction along the progress of the vehicle is converted into the force in the traveling direction of the vehicle by the direction switching elastic body 1004.

In addition, one end 119 of the hydraulic transmission pipe 120 may be positioned as a power transmission means in the speed bumps 2005 shown. This is to transfer the force in the driving direction of the vehicle by the direction switching elastic body 1004 to a place suitable for installing the air pump.

In the illustrated case, there is a disadvantage in that the structure of the speed bump is complicated, but the efficiency of receiving the mechanical energy is high, and there is an advantage in that the durability of the outer case of the speed bump and the reversible elastic body inside is increased.

10 illustrates an in-phase power generation system using a speed bump according to an embodiment of the present invention.

The illustrated power generation system includes a direction switching elastic body that converts a force in a vertical direction due to the weight of the vehicle into a horizontal force and imparts a restoring force of the speed bumps 110; An air pump 140 as an air compression unit that compresses air by using a horizontal force of the direction change elastic body; An air tank 160 for accumulating air pressure; An injection nozzle (164) for injecting air compressed by the air compression means into the air tank as an air pressure injection unit for injecting the air pressure by the air pump 160 into the air tank; And it may include a generator 190 for generating electricity by driving with the air pressure accumulated in the air tank 160. A hydraulic transmission pipe 120 may be further included as a power transmission unit for transmitting a horizontal force of the reversible elastic body to the air pump 140.

The illustrated speed bump 110 may include an outer frame including the direction change elastic body and the direction change elastic body therein and forming an outer shape of the speed bump. In addition, the outer frame may include a cover plate forming a protruding surface to the top of the road and pressurizing the elastic body for the direction change in the vertical direction, and a shielding film for preventing foreign matter from flowing into the inside.

Here, the direction switching elastic body may have a leaf spring structure of a shape that is unfolded by the vertical force, that is, the structure shown in Figs. 1A to 9.

The illustrated air pump 140 reciprocates the piston 144 by receiving a force for expanding the direction change elastic body by the weight of the vehicle, and the air compressed by the piston 144 is the air tank ( 160). For convenience of management, when the air pump 160 is positioned at a point away from the speed bump 110, a hydraulic transmission pipe 120 may be used as shown.

The piston 144 compresses air by the force determined by the elastic body for direction change by the weight of the vehicle, and performs the reciprocating motion to return to the original position by the elastic force of the direction elastic body. A check valve type intake valve 148 may be provided to suck air to be compressed by the air pump 140.

The air compressed by the piston 144 is introduced into the air tank via the spray nozzle 164 shown. The injection nozzle 164 is provided with a check valve 168 as a blocking structure so that the introduced air does not leak in the reverse direction.

It is preferable that the cross-sectional area perpendicular to the air compression direction of the piston 144 has a structure that is much larger than the cross-sectional area perpendicular to the air injection direction of the end of the injection nozzle 164. (At least the cross-sectional area of the piston 144. 4 times or more than the cross-sectional area of the said injection nozzle 164 is suitable.)

Accordingly, the air pump 140 may introduce air into the air tank 160 having an internal air pressure higher than the pressure pushing the piston 144 of the air pump 140. This is because the compression of the piston 144 of the air pump 140 is possible because of the large area, while the volume of air compressed and passed through the nozzle 164 is small and has a high pressure.

The air pump 140 of the structure has the advantage that the structure is very simple to reduce the manufacturing cost.

An air motor 180 may be provided between the generator 190 and the air tank 160 to rotate the compressed air inside the air tank 160. In addition, an air valve 170 may be provided between the air tank 160 and the air motor 180 to release / regulate the compressed air in the air tank 160.

In another embodiment, the battery 190 may further include a rechargeable battery (not shown) for storing electricity generated from the generator 190.

In another embodiment, as the air pump 140, a rotary compressor used for a vacuum pump or the like may be applied. Alternatively, other air pumps or vacuum pumps may be applied. When using a rotary air pump such as the rotary compressor, there is a disadvantage in that the structure is complicated, but there is an advantage that can accumulate a higher air pressure in the air tank.

FIG. 11A illustrates another embodiment of the air pump drive structure applicable to the on-grid power generation system of FIG. 10.

The illustrated air pump drive structure includes a speed bump 110 having an elastic body for changing direction; Air pump 140; And a universal coupling (joint) 4201 as a power transmission means for transmitting the force of the turning elastic body to the air pump. The illustrated air pump drive structure has a very simple structure, but when it has a simpler structure, the universal coupling (joint) 4201 is omitted, and the reversible elastic body and the air pump 140 are simple rod-shaped objects. ) Can be connected.

FIG. 11B illustrates another embodiment of the air pump drive structure applicable to the on-grid power generation system of FIG. 10.

The illustrated speed bump 110 'converts the force due to the weight of the vehicle into a direction extending to both ends of the direction switching elastic body. The force exerted on both ends of the resilient elastic body is a rotary air pump via the three-port hydraulic transmission pipe 4302, the universal coupling (joint) 4201, the crank arm 4512, and the crank 4502. Drive (4802).

FIG. 11C illustrates another embodiment of the air pump drive structure applicable to the on-grid power generation system of FIG. 10.

The illustrated speed bump 110 converts a force due to the weight of the vehicle into a force for extending the right side of the elastic body for direction change. The force exerted by the resilient body for change of direction is converted into rotational force via the hydraulic transmission pipe 120, the universal coupling (joint) 4203, the crank arm 4513, and the crank 4503. The rotational force is converted to an appropriate rotational speed by the transmission 4603 to drive the rotary air pump 4803.

That is, the illustrated air pump drive structure includes a transmission 4603 as a transmission for adjusting the transmission ratio between the rotary air pump 4803 and the directional elastic body. In the figure, the hydraulic transmission pipe 120, the universal coupling (joint) 4203, the crank arm 4513, the crank 4503, and the transmission 4603 constitute a power transmission unit.

When the transmission 4603 is used, the transmission ratio for driving the rotary air pump 4803 can be set differently according to the air pressure in the air tank, thereby increasing energy storage efficiency. Here, the air tank may be provided with an air pressure sensor for measuring the air pressure therein.

That is, when the air pressure inside the air tank is low, the rotation speed of the rotary air pump 4803 is increased per one reciprocation of the directional elastic body, and when the air pressure inside the air tank is high, the direction change The rotation speed of the rotary air pump 4803 can be controlled less per one round trip of the elastic body.

In another implementation, a transmission may be provided in the power transmission unit for the reciprocating air pump of FIG. 10.

12A illustrates another embodiment of a generator drive structure in the on-grid power generation system of FIG. 10.

In the illustrated structure, a transmission 6401 is provided between the air motor 6201 and the generator 190. This is because the pressure of the compressed air ejected from the air tank 160 fluctuates with time, so that the direct connection between the air motor 6201 and the generator 190 prevents the power generation efficiency of the generator 190 from dropping. . That is, the transmission 6401 may be set to a transmission ratio suitable for power generation according to the pressure of the air tank 160.

FIG. 12B illustrates another embodiment of a generator drive structure in the on-grid power generation system of FIG. 10.

In the implementation shown in FIG. 12B, the air tank may have a double cylinder structure. That is, in this case, the air tank includes an input tank 7101 that receives air from the air pump, and an output tank 7201 for outputting internal air to the air motor 180. A valve or a check valve can be provided between the output tanks 7201. The valve or check valve will be referred to as an intermediate valve 7301.

While accumulating air pressure, the intermediate valve 7301 is kept open, and the internal air pressure of the input tank 7101 and the output tank 7201 are the same. When the internal air pressure accumulated in the output tank 7201 exceeds the reference value for generation, the intermediate valve 7301 is closed, and then the power generation valve 170 is opened to allow the internal air to flow out to the air motor 180. Accordingly, even when the power generation valve 170 is opened, the input tank 7101 may be kept in a closed state to continuously accumulate air introduced from the air pump. Thereafter, when the power generation ends, the intermediate valve 7301 may be opened after closing the power generation valve 170.

It should be noted that the above embodiment is for the purpose of illustration and not for the purpose of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
