Description

Trash removal machine with thermoelectric power generation function

The present invention relates to a vibration damper having a thermoelectric power generation function, and more particularly, to a vibration damper having a thermoelectric power generation function capable of generating electricity using thermal energy of sunlight incident on the vibration damper.

A water channel is generally used as a passage for water to flow, and it is exposed to the ground and becomes a passage through which floating matter such as various plants and garbage are washed away together with water. Floating objects moving through the waterway can block the waterway and cause water to overflow or cause the collapse of facilities such as embankments. In order to remove these floating matter, a vibration damper is usually used.

A vibration damper is a device that is installed in waterways provided in sewage treatment plants, drainage pumping stations, small-scale power plants, and other industrial sewage treatment plants to collect various floating materials that obstruct the flow of water. Vibrators operate in special situations, such as heavy rain, to remove floating matter that has floated through waterways, and some are submerged in water, while others are always exposed above the water. In particular, most of the parts exposed above the water are exposed to sunlight, and the surface temperature sometimes rises very high, such as in summer.

Such a vibration damper is not a device normally used, but operates in the rainy season or in a heavy rain situation when a lot of floating matter is washed down through a waterway. That is, as it operates less than a few times a year, a major accident may occur if the operation is not performed properly at a time when the operation is suddenly necessary. For example, when power is temporarily cut off due to a flood, etc., floating objects in a waterway cannot be removed, so problems such as flooding or collapse of an embankment may occur.

1 and 2, the vibration damper 1 having a thermoelectric power generation function according to the present invention is a device for filtering floating matter flowing in the water channel 10 out of the water channel 10, and when not in use, the thermoelectric generator 200 ) to generate and store electricity. The vibration damper 1 with thermoelectric power generation function is installed in a waterway, so the temperature on the front side that is always exposed to sunlight rises very high during the day, and the rear side that is covered by the device is always in the shade, so the temperature is low. The vibration damper 1 according to the present invention generates electricity by using the temperature difference between the front and rear surfaces to reduce power consumption and can be used as power in an emergency or as idle power. In addition, the thermoelectric generator 200 may store the generated electricity in the battery part 300 , so that even if the instantaneous amount of power generated by the thermoelectric generator 200 is not large, it can be sufficiently utilized as emergency power. For example, considering that the period in which the vibration damper 1 operates is usually several times a year or less, even if the amount of charge is small, if the battery unit 300 is charged over several months, the power demand can be sufficiently met, and the amount of charge If this certain amount is maintained, power may be supplied to other power consuming places (eg, street lights, surveillance cameras, etc.) around the vibration damper 1 . Furthermore, the thermoelectric power generation unit 200 is capable of small-scale and independent power generation using thermal energy, and it can be used as a combined power source together with other power sources, so it is a very useful power generation technology, and the vibration suppressor 1 can be used on a large scale. The installed facility may serve as a small power plant. In particular, the thermoelectric power generation unit 200 can generate eco-friendly power without the generation of carbon dioxide, so the potential for future power generation is very high. Hereinafter, each configuration of the vibration damper 1 having a thermoelectric power generation function will be described in detail.

The vibration damper 1 having the thermoelectric power generation function of the present invention is configured as follows. The vibration damper 1 having a thermoelectric power generation function overlaps with the entrance of the water channel and includes a screen 120 with a gap 122 through which water passes and a blocking part for blocking floating objects floating in the water flow, and extends from the top of the screen 120. A plate-shaped apron 115 having a guide surface 116 for guiding floating objects rising along the screen 120, and a frame 110 that fixes the screen 120 and the apron 115 and is supported on the wall surface of the waterway (110) And, a chain driving unit 130 installed in the frame 110 and continuously rotating in one direction along the circumference of the frame 110 , and one end is coupled to the chain driving unit 130 and continuously moves together with the chain driving unit 130 . And a rake 160 that kicks up floating objects caught on the front of the screen 120 and raises it to the top of the apron 115 through the screen 120, and a motor driving unit 140 that rotates and drives the chain driving unit 130, and a motor driving unit ( 140), the battery unit 300 for supplying power, and the guide surface 116 and the opposite side of the apron 115 in contact with the back 117 of the apron 115 using the temperature of the apron 115 to generate electricity to the battery unit It includes a thermoelectric power generation unit 200 to be stored in (300).

The frame 110 is an external support structure having an outer surface fixed to the water channel 10 to support the screen 120 and the apron 115 on the inner surface. The lower end of the frame 110 is submerged in the water channel 10 , and the upper end is exposed as the upper end of the water channel 10 . The frame 110 may have a pair of frames 110 of the same shape facing each other, and the outer surfaces may be in close contact with the wall surface of the water channel 10 , respectively. A screen 120 and an apron 115 are interposed between the pair of frames 110 , and the screen 120 is coupled to the lower end of the frame 110 to block floating objects flowing in the water channel 10 .

The screen 120 overlaps the water channel 10, and a gap 122 through which water can pass is formed, so that water flows but only floating matter can be selectively blocked. The screen 120 is composed of a plurality of screen bars 121 forming a blocking film, and a gap 122 that is a spaced apart space exists between each screen bar 121 . The screen 120 completely overlaps one section of the water channel 10 and is fixed to be inclined with the bottom surface of the water channel 10 .

The screen bar 121 serves as a blocking bar for filtering floating matter, and the gap 122 formed between the screen bars 121 becomes a space through which water passes. The screen bar 121 is vertically arranged with the bottom surface of the water channel 10 , and there is a gap 122 between each screen bar 121 , so that only floating matter can be filtered without blocking the flow of water. In addition, the lower surface of the screen 120 is spaced apart from the bottom of the water channel 10, the potential screen 123 for blocking the spaced space may be installed. The potential screen 123 is configured such that a plurality of screen bars 121 are spaced apart from each other in the same manner as the screen 120 , and thus may perform the same function as the screen 20 . In addition, an apron 115 for guiding the float transferred to the upper end of the screen 120 is positioned at the upper end of the screen 120 .

The apron 115 is a plate-shaped member extending from the upper end of the screen 120 and guiding the floating object rising along the front surface of the screen 120 . The apron 115 has a guide surface 116 formed on its front surface to guide the transported float. The apron 115 is spaced apart from the upper end of the water channel and is exposed to the outside without being submerged in water, unlike the screen 120 , and is exposed to sunlight as it is and is heated to a high temperature during the day. The apron 115 is usually made of a metal material and the heat incident on the guide surface 116 is easily transferred to the rear surface portion 117 . In particular, the apron 115 is formed to be inclined with the ground so that the front side is easily exposed to sunlight, but the rear side is mainly formed of a shade zone and the sunlight does not enter it well, so a temperature difference is inevitable on both sides. Accordingly, it is possible to produce electricity by attaching the thermoelectric generator 200 to the rear portion 117 . The structure of the thermoelectric generator 200 will be described in detail later.

The apron 115 and the screen 120 constitute a large-area body portion of the vibration damper 1 having a thermoelectric power generation function. The area portions of the apron 115 and the screen 120 are formed to face the water channel 10 , and both ends are fixed to the frame 110 . That is, the screen 120 and the apron 115 are inclinedly fixed structures, and the float filtered by the screen bar 121 of the inclinedly fixed structure is taken out of the water channel 10 by the moving rake 160. .

The rake 160 functions to remove the floating matter caught on the screen 120 . The rake 160 rises in the longitudinal direction from the front of the screen 120 and transports the float caught on the screen 120 to the rear of the apron 115 through the guide surface 116 of the apron 115 . The rake 160 mainly rotates in one direction and rises along the guide surface 116 from the front of the screen 120 , and may descend at the rear of the apron 115 . At this time, the rake 160 can move along the inclined screen 120 and the apron 115 to more stably transport the float.

In addition, in a situation where the rake 160 cannot proceed due to a floating object caught between the screen 20 and the rake 160 or between the apron 115 and the rake 160, temporarily rotate the rake 160 in the reverse direction to After removing the jammed floating object, normal operation can be resumed in the forward direction. That is, the rake 160 may be rotated in both directions depending on the situation.

Both ends of the rake 160 are coupled to the chain driving unit 130 to rotate together. The rake 160 may be fixed to the chain driving unit 130 or coupled to be detachably attached. The cross-section of the screen 120 side of the rake 160 may have a flat shape and be formed perpendicular to the screen bar 121 . The outer surface of the rake 160 may have a curved shape to more effectively filter out floating matter. In the present specification, the rake 160 may have a triangular protruding shape to more efficiently filter the float. The shape of the rake 160 is not limited thereto, and various modifications are possible as needed.

On the other hand, the chain driving unit 130 serves to transmit power to the rake 160 . The chain driving unit 130 is coupled to the rake 160 on the inside of the frame 110 to continuously rotate together indefinitely. The chain driving unit 130 rotates along the circumference of the frame 110 and reciprocates between the upper and lower sides of the frame 110 . A pair of driving gears 145 formed parallel to and spaced apart from the frame 110 are positioned at both ends inside the frame 110 . Both ends of the chain driving unit 130 are engaged with the driving gear 145 and driven according to the rotation of the driving gear 145 .

The chain driving unit 130 rotates infinitely in one direction together with the rotation of the driving gear 145 engaged with both ends. The driving gears 145 respectively formed on the pair of frames 110 may be connected to a driving shaft (not shown) to rotate at the same speed. The driving gear 145 rotates while being inserted into the empty space between each node of the chain driving unit 130 like a sprocket. The chain driving unit 130 is engaged with the driving gear 145 positioned at the upper end and the lower end of the frame 110 , and rotates, and rotates at the same speed as the rotating speed of the driving gear 145 . The driving gear 145 at the upper end of the frame 110 may be connected to the power transmission shaft 146 to receive power. The driving gear 145 may be connected to the power transmission gear 142 via the power transmission shaft 146 .

The power transmission gear 142 receives power generated from the motor driving unit 140 through the power transmission chain 143 , and transmits it to the driving gear 145 connected to the power transmission shaft 146 . That is, the driving gear 145 and the power transmission gear 142 may be double gears sharing the same shaft. The opposite side of the power transmission gear 142 may be connected to the gear unit 150 .

The gear unit 150 is to allow the rake 160 to be operated manually, and is installed on the deck 400 so that the operator can easily access it. The gear unit 150 is connected to the power transmission gear 142 to separately transmit power even when power is not transmitted from the motor driving unit 140 . For example, even if the power is cut off and the motor driving unit 140 stops operating, the manager may go up to the deck 400 and rotate the handle unit 151 to manually operate the chain driving unit 130 . In addition, the gear unit 150 may include a reverse rotation limiting device capable of rotating in only one direction, such as a ratchet.

One side of the gear unit 150 is connected to the power transmission gear 142 and a handle unit 151 is attached to the opposite side thereof. The gear unit 150 may drive the rake 160 by transmitting a force that a person manually pulls the handle unit 151 to the power transmission gear 142 . The gear unit 150 may be connected to the power transmission gear 142 and the gear shaft 147 , and may transmit the rotation of the gear unit 150 to the power transmission gear 142 . The gear unit 150 may be driven by the handle unit 151 , and the handle unit 151 may have a shape extending from the center of the gear unit 150 . Since the end of the handle unit 151 is far from the center of the gear unit 150, when manually operated, the end of the handle unit 151 is pulled and a large power can be transmitted with a small force using the principle of a lever. In addition, since the gear unit 150 has a structure that can rotate in only one direction, when the handle unit 151 is pulled in a predetermined direction, it automatically returns to its original position and can be driven by repeating the process of pulling it again in a predetermined direction. The reverse rotation limiting device prevents the gear from rotating in reverse when a person operates the gear unit 150 using the handle unit 151 so that the chain driving unit 130 can rotate constantly in one direction. That is, the rake 160 can be rotated in one direction to constantly pick up the floating material from the water channel 10 . Due to the reverse rotation limiting device, the handle portion 151 moves only within a certain angle and takes up little space, so it can be installed in a narrow space.

On the other hand, the conveyor belt 180 is installed on the ground at the top of the waterway, it can receive and transport the float filtered by the rake (160). The float moves along the conveyor belt 180 and is sent to a space where it can be disposed of or reused. The conveyor belt 180 may rotate the upper roller 181 and the lower roller 182 in the same direction, and the drive belt 185 in contact with the upper surface of each may rotate in one direction. Conveyor belt 180 may be installed at a position where the rake 160 rotates to change direction and a falling floating object is seated. The conveyor belt 180 may have a plurality of upper rollers 181 formed therein in order to receive such floating matter well. The configuration or operation of the conveyor belt 180 is not limited thereto, and it can be modified into various shapes capable of transporting floating objects. In addition, the conveyor belt 180 may have a structure in which the upper end is covered with the deck 400 , except for a section in which the float is seated from the rake 160 . That is, the deck 400 is positioned at the upper end of the conveyor belt 180 to protect the transport section of the conveyor belt 180 .

The deck 400 is installed in parallel on the upper part of the waterway to function as a foothold for the operator, and may also function as a shade film to block sunlight incident on the rear surface of the apron 115 . The deck 400 is installed parallel to the upper end of the apron 115 , and thus a shade film can be formed at the lower end of the deck 400 . That is, the deck 400 can form a shade film on the rear of the apron 115 to maintain a low temperature.

On the other hand, the thermoelectric generator 200 is attached to the rear portion 117 of the apron 115 to produce electricity using the temperature difference between the front and rear. As shown in FIG. 2 , the thermoelectric generator 200 may be installed in close contact with the back surface of the inclined apron 115 . The thermoelectric generator 200 may be formed by arranging a plurality of thermoelectric elements 210 side by side, and a heat sink 220 having a cooling function may be attached to the rear surface of each thermoelectric element 210 . That is, the apron 115 to which the thermoelectric element 210 is attached is always heated by receiving sunlight to maintain a high temperature state, and a heat sink 220 is attached to the back of the thermoelectric element 210 to maintain a cooling state. . In addition, the deck 400 is located at the rear of the apron 115, and the apron 115 is also formed to be inclined to block sunlight incident on the thermoelectric element 210 or the heat sink 220 side to maintain a lower temperature. .

The thermoelectric generator 200 may be connected to the battery unit 300 to store electricity produced in the battery unit 300 . The thermoelectric generator 200 stores power in the battery unit 300 in preparation for an emergency situation in which the motor driving unit 140 is stopped, and in an emergency situation, the motor driving unit 140 receives electricity from the battery unit 300 . can make it work again. In addition, when the battery unit 300 stores more than the reference electricity used for emergency power, the battery unit 300 may provide extra electricity to other nearby devices. For example, the battery unit 300 may provide electricity to a nearby street lamp or a conveyor belt 180 that is always used.

Hereinafter, the structure and principle of the thermoelectric generator will be described in more detail with reference to FIGS. 3 and 6 .

Figure 3 is a rear perspective view of the apron of Figure 1, Figure 4 is a view schematically showing the function of the thermoelectric generator of Figure 3, Figure 5 is a rear perspective view of the apron in which the thermoelectric generator according to another embodiment of the present invention is installed, 6 is a rear perspective view of an apron installed with a thermoelectric generator according to another embodiment of the present invention.

Referring to FIGS. 3 and 4 , the thermoelectric generator 200 is located on the rear surface 117 of the apron 115 , and generates electricity using the temperature difference between the front and rear sides of the apron 115 . The thermoelectric generator 200 includes a thermoelectric element 210 and a heat sink 220 attached to the thermoelectric element 210 , and may generate electricity using a temperature difference between the front and rear surfaces of the thermoelectric element 210 .

The thermoelectric element 210 includes a high-temperature portion 211 attached to the rear surface 117 of the apron 115 and a low-temperature portion 212 to which a heat sink 220 is attached from the opposite side to emit heat. The high temperature part 211 is in close contact with the apron 115 having thermal energy by sunlight to maintain a high temperature. The low temperature part 212 is spaced apart from the rear part 117 of the apron 115 and is located at the rear of the apron 115 , and a heat sink 220 is attached thereto to maintain a low temperature. In particular, the low-temperature part 212 can maintain a lower temperature by being shielded from sunlight by the structure of the apron 115 having an inclination and the deck 400 as well as the heat sink 220 . In addition, both ends of the thermoelectric generator 200 are surrounded by the frame 110 so that light from both sides can also be blocked, and accordingly, the rear surface of the apron 115 can always maintain a low temperature as a shaded area. Furthermore, the thermoelectric generator 200 is a structure accommodated inside the frame 110 , and has a structure capable of producing electricity without interference with the operation of the chain driving unit 130 and the rake 160 .

As shown in FIG. 3 , the thermoelectric generator 200 according to the present invention is configured with a plurality of thermoelectric elements 210 to store electricity generated by each of the thermoelectric elements 210 at once. One side of the plurality of thermoelectric elements 210 is attached to the rear portion 117 of the apron 115 , and a heat sink 220 is attached to the other side, respectively. In addition, the plurality of thermoelectric elements 210 may be arranged side by side or randomly, and the arrangement method may be variously modified according to the rear structure of the apron 115 .

Referring to FIG. 5 , a thermoelectric generator 200 - 1 according to another exemplary embodiment of the present invention may be configured as a single thermoelectric element 210 - 1 . The single thermoelectric element 210 may be formed in a size large enough to cover the rear surface of the apron 115 . The heat sink 220 - 2 attached to the single thermoelectric element 210 - 1 may also have a single large shape. Also, referring to FIG. 6 , the thermoelectric generator 200 - 2 according to another embodiment of the present invention may be divided into two thermoelectric elements 210 - 2 and disposed. That is, referring to FIGS. 3, 5 and 6 , the thermoelectric elements 210 , 210 - 1 , and 210 - 2 and the heat sink 220 constituting the thermoelectric generators 200 , 200 - 1 and 200 - 2 , 220-1 and 220-2) can be variously modified in size, shape, or number.

Hereinafter, an operation process of the vibration damper having a thermoelectric power generation function will be described in more detail with reference to FIGS. 7 and 9 .

7 is a view showing the normal operation of the vibration damper with thermoelectric power generation function of FIG. 1 , FIG. 8 is a view showing that the vibration damper with thermoelectric generation function of FIG. 1 is cut off, and FIG. 9 is the vibration damper with thermoelectric generation function of FIG. of emergency operation.

Referring to FIG. 7 , in the normal operation process of the vibration damper 1 having a thermoelectric power generation function, the thermoelectric power generation unit 200 continuously stores electricity in the battery unit 300 , and at the same time the rake 160 rotates in a clockwise direction. It can be rotated to filter the floating matter (20). The rake 160 may transfer the floating material 20 flowing in with water flowing in front of the screen 120 to the conveyor belt 180 . In addition, when there is not much water flowing in the water channel 10 and the water level is low, for example, in the case of FIG. 7 , the rake 160 may rotate slowly. Alternatively, when the water in the water channel 10 stops without flowing, the rake 160 may also stop. That is, the rotational speed of the rake 160 may be adjusted according to the amount of water flowing in the water channel 10 to maintain a stable state of the water channel 10 .

Referring to FIG. 8 , when a natural disaster such as a large-scale blackout or flood occurs, the vibration damper 1 having a thermoelectric power generation function may stop driving because electricity is cut off. When the external power of the vibration damper 1 having a thermoelectric power generation function is cut off, the motor driving unit 140 stops operation and the rake 160 stops. If the rake 160 stops and does not rotate, the floating material cannot be filtered and is accumulated in front of the screen 120 . Although water continues to flow in the water channel 10 in front of the screen 20 , the water does not pass smoothly through the screen 20 due to the floating matter accumulated on the front surface of the screen 20 , and the flow rate is lowered. If this state continues, the amount of water flowing in from the front of the screen 20 is greater than the amount of water that can pass through the screen 20, and eventually the water level in front of the screen 120 increases, and the floating matter 20 continues to accumulate. .

Referring to FIG. 9 , in a state in which the external power is cut off, the vibration damper 1 having a thermoelectric power generation function may perform emergency driving with electricity stored in the battery unit 300 . That is, the battery unit 300 may provide power to the motor driving unit 140 , and accordingly, the motor driving unit 140 may operate the rake 160 again to filter out floating matter. The electricity stored in the battery unit 300 may be less than the amount of electricity received from the existing power source, and accordingly, the rotational speed of the rake 160 may be down-regulated to perform minimal driving with a small amount of electricity. For example, in normal operation, the rotation speed of 5 m per minute can be reduced to about 0.5 m per minute and can be driven. In this emergency, if the rake 160 is slowly driven by the thermoelectric generator 200 to filter the floating material 20, the screen 120 is not blocked and the flow of water can be maintained. After that, when the power cut-off problem is solved and the power is turned on, stable operation at normal speed is possible.

When the handle portion 151 is manually operated, the rake 160 is manually rotated and the floating material 20 is filtered. The handle portion 151 is designed to be driven in only one direction like a ratchet structure, so there is no need to worry about the rake 160 rotating in the reverse direction. When the floating matter 20 in front of the screen 120 is filtered to some extent by manual manipulation, the flow of water flowing in the water channel 10 is restored and the water level in the front and rear of the screen 120 can be similar. The water level may be increased by the water accumulated in front of the screen 20 .
