The present invention relates to a vibration damper, and more particularly, to a vibration damper that facilitates the cleaning work of deposited dust or dirt on a locked part by raising the damper to a predetermined height so as to escape to the outside of a waterway.

Generally, the damper is installed on various waterways such as drainage pumping station, water supply water intake system, sewage treatment plant, and related water supply system, and removes the impurities contained in the water by pulling it up to the upper part of the waterway.

The damper is installed between the guide rail and the guide rail on both sides of the frame, and is installed at an angle to the floor surface to filter out the dirt that flows along with the water stream. A disposable screen provided at a lower front end of the screen for filtering contaminants passing between the screen and the bottom surface and a rake rake provided at both the left and right ends of the screen for removing contaminants between the screen and the disposable screen do.

When such a damper is installed in the water channel and is not operated, the lower portion of the damper is continuously immersed in the water, so that there is a problem that the lower portion of the damper is damaged or broken by a small obstacle which is not lifted by the soil loss settled in the water channel.

In the case of repairs or replacement of parts due to problems such as screens or chains of the damper, it is necessary to prevent water in the waterway and replace it at the lower part, so that the production cost is increased due to construction and maintenance and there is a problem in working efficiency.

Since the damper is mounted directly on the wall surface of the pumping station and the repair channel, the angle of the screen can not be moved, and the water channel can not be separated from the water, which makes maintenance work difficult.

In order to solve such problems, it is an object of the present invention to provide a vibration damper for raising a vibration damper to a predetermined height so as to escape to the outside of a waterway, thereby facilitating the cleaning work of the dirt and the dirt.

According to an aspect of the present invention, there is provided a vibration damper comprising: a main screen having a plurality of diaphragms disposed between guide rails provided on both sides of a frame to filter contaminants flowing along with water streams; And a driving motor for driving the rake, the vibration damper comprising:

A hydraulic cylinder is installed at the rear of the frame or at the upper end of the frame so that the frame attached with the main screen and the dislocation screen are lifted at a predetermined height, and the rake is formed in a straight line shape and its end portion is curved at a certain angle .

According to the above-described structure, the damper is lifted up to a predetermined height to be released to the outside of the waterway, thereby facilitating the cleaning work of the deposited soil or the dirt in the locked area.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

FIG. 1 is a perspective view showing the construction of a vibration damper according to a first embodiment of the present invention, FIG. 2 is an enlarged view of an area A in the vibration damper according to the first embodiment of the present invention, FIG. 4 is an enlarged view of a region C in the vibration damper according to the first embodiment of the present invention. FIG.

The vibration damper 100 according to the first embodiment of the present invention includes a frame 110 installed at the entrance of a water channel structure, a guide rail 114 installed on both sides of the frame 110, A main screen 120 installed at a lower portion of the main screen 120 and provided at a lower portion of the vibration damper 100 for filtering contaminants or foreign matter, And a rake type rake 140 that moves along the dislocation screen 130 and the main screen 120 to remove contaminants or foreign matter caught on the main screen 120. [

The frame 110 is installed at the entrance of the waterway structure to support the main screen 120 and the rake rake 140.

The frame 110 includes a lifting chain 123 which is formed at an upper portion of the frame 110 so as to be bent backward and installed inside.

The frame 110 is elongated vertically and has an upper portion bent backward and two portions disposed opposite to each other, and a main screen 120 is installed therebetween.

A lifting chain 123 is installed inside the frame 110 and is circulated therein and a driving motor 124 is installed at one end of one of the two frames 110, .

In order to smoothly operate the lifting chain 123, the upper and lower ends of the frame 110 are preferably curved.

An apron 125 is provided at the upper end of the frame 110 to block water from entering the portion except for the main screen 120 and to prevent the lifted suspended matter from falling into the water channel.

The apron 125 is provided for guiding rearward the rake rake 140 filtered by the obstacle 20 to collect the contaminants 20 and is formed to extend from the upper end of the main screen 120 to the upper side in a plate- And an inclined surface 125a is formed at the lower end.

The main screen 120 is installed between the frame 110, that is, between the guide rails 114, and a plurality of blades 122 are vertically arranged and connected in parallel vertically, as shown in FIG. 3, It filters out the impurities that come off.

Displacement screen 130 is installed at the lower front end of main screen 120 to filter contaminants 20 passing between the bottom surfaces of the channels.

The rake rake 140 includes a plurality of rakes passing between the blades 122 as a device for removing the contaminants 20 caught by the main screen 120 and the electric potential screen 130, So as to stably support the impurities caught by the rake rake 140.

The rake rake 140 is connected to the lifting chain 123 and moves along the frame 110.

The lifting chain 123 is for continuously rotating the rake rake 140, and is mounted on both side guide rails 114 so as to be rotatable in one direction.

The rake rake 140 moves in such a manner that the rake rake 140 rises from the front side with respect to the frame 110 and descends from the rear side to circulate.

The rake rake 140 transports the contaminants filtered by the dislocation screen 130 and the main screen 120 in one direction.

The driving motor 124 transmits a driving force to a rotating shaft of a sprocket (not shown) rotated by engaging with the lifting chain 123. The conveyor 126 transports the impurities, which have fallen behind the apron 125, And is installed at the rear lower side of the apron 125. [

The rake rake 140 coupled to the lifting chain 123 is lifted from the front surface of the main screen 120 on the plurality of blades 122 of the main screen 120 and moved downward And is guided by the rail 114.

3 and 4, the rake rake 140 according to the first embodiment of the present invention is configured such that when the bottom of the main screen 120 is turned, all of the inner side surface 132 of the disconnection screen 130 The rake rake 140 is positioned within the turning radius of the turning radius.

The dislocation screen 130 of the present invention is formed in a curved shape bent at a certain angle and formed in the shape of a curve having the same shape as the radius of curvature so that the entire shape and the inner side surface 132 coincide with the radius of curvature of the rake rake 140, And a step portion 131 having a predetermined length in the horizontal direction.

Accordingly, the shape of the rake rake 140 is formed to correspond to the shape of the inner side surface 132 of the dislocation screen 130, so that the end 142 is curved at a certain angle, unlike the conventional rake.

The reason why the inner surface 132 of the dislocation screen 130 coincides with the radius of curvature of the rake rake 140 is that the rake rake 140 is formed as close as possible to the radius of curvature turning, In order to remove a rectangular area that the rake-shaped rake 140 can not reach.

The shape of the end portion 142 of the rake rake 140 is formed to correspond to the shape of the inner surface of the disposing screen 130 so that the radius of rotation of the rake rake 140 corresponds to the entire inner surface of the potential screen 130 Area.

FIG. 5 is a view showing a moving member for moving a potential screen of a vibration damper according to a second embodiment of the present invention, FIG. 6 is a front view of a moving member for moving a dislocation screen according to a second embodiment of the present invention, And FIG. 7 is a side cross-sectional view showing the configuration of the vibration damper of the second embodiment of the present invention.

5 to 7, the vibration damper 100 according to the second embodiment of the present invention includes a frame 110 installed on both sides of a water channel wall and a main screen 120 And a rake surface rake 140 that is rotated in an endless track along the guide grooves of the main frame 110. A discrete screen 130 spaced apart from the main screen 120 by a predetermined distance is disposed at a front lower portion of the damper 100, And is configured to sweep up the contaminants 20 caught by the main screen 120 and the electric potential screen 130 while the rake rake 140 of the vibration damper 100 is being transported.

The vibration damper 100 according to the second embodiment of the present invention has a structure in which a moving member 150 for moving forward and rearward of a disconnection screen 130 installed at a front lower part is coupled to a dislocation screen 130.

The dislocation screen 130 is spaced apart from the main screen 120 at a lower front end of the main screen 120.

A connection shaft 156 in the form of a bar in the horizontal direction is coupled to one side of the lower surface of the dislocation screen 130.

A body 154 is formed at both ends of the connection shaft 156 and a roller 155 is coupled to the inside of the body 154 so as to be rotatable forward and backward with respect to the connection shaft 156.

A spring 156a is inserted into the outer surfaces of both ends of the connection shaft 156 to allow elastic force between the body 154 and the connection shaft 156 when the body 154 is moved.

On the lower surface of the body 154, a sliding rail 157 coupled to the roller 155 is installed.

In other words, the sliding rails 157 are installed between the first fixing bracket 151 and the second fixing bracket 152 at regular intervals in the longitudinal direction on both sides of the front lower part of the main screen 120.

The body 154 is mounted on the sliding rail 157 and is moved back and forth along the sliding rail 157 by the roller 155.

Accordingly, as the body 154 is moved back and forth, the connection shaft 156 and the electric potential screen 130 connected to the body in the horizontal direction are also moved back and forth.

The first fixing bracket 151 and the second fixing bracket 152 serve as stoppers for the moving member 150 for moving the electric potential screen 130.

A spring member 153 is connected to the body 154 between the second fixing bracket 152 and the second fixing bracket 152.

In this way, the electric potential screen 130 of the vibration damper 100 is not fixed, but flows elastically in accordance with the speed and water pressure of the water flow.

For example, when the obstacle 20 is pushed and the dislocation screen 130 is caught, the water pressure of the water flow is increased by blocking a part of the water flow of the obstacle 20, And the water pressure of the water current is lowered. By this water pressure lowering, the electric potential screen 130 moves to the main screen 120 side.

For example, when the rotating rake rake 140 is lifted and removed by the obstacle 20, it is moved in a direction away from the main screen 120 side again.

FIG. 8 is a side sectional view showing the configuration of a vibration damper of a third embodiment of the present invention, and FIG. 9 is a perspective view showing the configuration of a vibration damper of the fourth embodiment of the present invention.

As shown in FIG. 8, the third embodiment additionally includes a damper lifting part 160 in the construction of the second embodiment.

The vibration damper 100 according to the third embodiment of the present invention is connected to the drive decelerator 163 and the drive motor 124 via the chain 164 and the chain 164 is coupled to the drive sprocket (not shown) .

The driving motor 124 transmits a driving force to a rotating shaft of a sprocket (not shown) rotated by engaging with the lifting chain 123 and drives the rake rake 140 connected to the lifting chain 123 to rotate the main screen 120 ) And the dislocation screen (130).

The tilting cylinder 162 is constructed such that the first hinge pin 161 is coupled to the first hinge pin 161a and the second hinge pin 165 is coupled to the second hinge pin 165a coupled to the vibration damper 100 .

The damper lifting unit 160 drives the tilting cylinder 162 to drive the damper 100 at a predetermined interval so that the drive reducer 163 is driven and the chain 164 connected to the drive reducer 163 is driven And is lifted away from the vibration damper 100.

Although the damper lifting part 160 of the present invention is illustrated as being coupled to the damper 100 of the second embodiment, it is not limited thereto and may be coupled to the damper 100 of the first embodiment.

In addition, a hydraulic cylinder may be installed on the rear surface of the frame 110 to further smooth the vertical movement of the vibration damper 100.

9, the fourth embodiment is different from the second embodiment in that a plurality of pinion gears 128 and a drive motor 129 for driving the pinion gears 128 are integrally provided at predetermined intervals on the rear surface of the frame 110, The pinion gear 128 of the pinion gear 128 rotates in engagement with the rack gear 127 on a fixed frame having a length corresponding to the frame 110. [

The pinion gear 128 and the rack gear 127 are engaged with each other by the drive motor 129 so that the frame 110 is vertically moved in the vertical direction.

When the drive motor 129 is operated in the forward direction, the rack gear 127 of the fixed frame and the pinion gear 128 are engaged with each other in the clockwise direction, thereby rotating the frame 110 vertically.

When the drive motor 129 is operated in the reverse direction, the rack gear 127 of the fixed frame and the pinion gear 128 are engaged with each other in the counterclockwise direction, and the frame 110 is vertically moved in the downward direction.

11 is a view showing a configuration of a dislocation screen according to a fourth embodiment of the present invention, and Fig. 12 is a sectional view of the dislocation screen according to the fifth embodiment of the present invention. Fig. Fig.

As shown in FIG. 10, the third embodiment additionally includes a distance sensing sensor module 170 installed at a predetermined distance from the moving direction of the electric potential screen 130 in the configuration of the second embodiment.

In other words, when the dislocation screen 130 and the body 154 move in a direction toward the main screen 120 due to a rise in the water pressure or a rise in the flow speed of the water, the displacement of the dislocation screen 130 and the body 154 The distance sensing sensor module 170 which is spaced apart from the sensor 170 senses a reduced distance when the distance between the potential screen 130 or the body 154 and the sensor 170 is reduced to a preset distance range.

The detection bar 130 is horizontally disposed on the upper side of the main screen 120 and the sensing bar 133 is disposed on the upper side of the dislocation screen 130. The distance sensor module 170 is disposed in a direction in which the potential screen 130 approaches the main screen 120 When the distance between the sensing bar 133 and the sensor 170 is reduced to a predetermined distance range, the distance is detected.

Here, the distance sensor module 170 is installed on the inner surface of the frame 110 at the same height as the sensing bar 133 described above.

The distance sensor module 170 converts the sensed information into an electrical signal and transmits the electrical signal to a control box (not shown) for controlling the rotation of the driving motor 124.

The distance sensor module 170 includes a rubber O-ring 172 and a rubber O-ring 172 for stably fixing the infrared ray guide 171 into which the thermo-filament sensor 173 is inserted and the thermo-filament sensor 173 inserted into the infrared- A fixing pipe 175 is used and a printed circuit board 176 is screwed on the rear surface of the infrared ray guide 171.

The thermopile sensor 173 is mounted on the printed circuit board 176 and electrically connected to the thermopile sensor 173, and a condenser lens 174 for condensing the infrared rays is installed at the front end. The thermopile sensor 173 is an infrared heat sensor mainly used for non-contact measurement of a stationary object, as generally known.

The distance detection sensor module 170 detects the movement of the main screen 120 toward the distance sensor module 170 within a predetermined distance as the potential screen 130 and the body 154 rise in water pressure, Converts it into an electrical signal and sends it to a control box that controls the rotation of the drive motor 124, which allows the control box to start or speed up the rotation of the drive motor 124.

When the water pressure of the dislocation screen 130 and the body 154 weakens and the main screen 120 moves away from the distance sensor module 170 by a predetermined distance or more, the distance sensor module 170 outputs an off signal to the control box And turns off the drive motor 124. [

The vibration damper 100 operates the drive motor 124 when the detection signal for starting the rotation operation of the drive motor 124 is received from the distance detection sensor module 170 and drives the drive motor 124 And the drive motor 124 is not operated when the detection signal is not received, thereby preventing unnecessary power wastage, thereby reducing power consumption and maintenance cost.

For example, the distance sensor module 170 may be constructed by configuring an infrared ray receiver with a predetermined distance from the infrared ray transmitter, and further, Any configuration and apparatus can be used.

As shown in Fig. 11, the fourth embodiment is similar to the second embodiment except that the structure of the second embodiment includes a body 184, 187, a sensor 182, a moving member 183, 180).

The body 184 and the body 187 are formed in a block shape by a member forming the outer shape of the object sensing part 180 and a receiving part 185 penetrating from one side to the other side is formed at the central part.

The accommodating portion 185 is provided with a moving member 183 in a cylindrical through hole and the moving member 183 has a pair of protruded contact portions 181 formed at the front end thereof and a sensor portion It is inserted and fixed.

The sensor unit (not shown) is provided with a connection wire 188 for transmitting electrical and control signals to the proximity sensor.

The elastic member 186 is located in the receiving portion 185 so as to surround one side of the moving member 183.

The elastic member 186 is inserted into the receiving portion 185 so that one side of the elastic member 186 is engaged with the receiving portion 185.

The movable member 183 can move in the longitudinal direction while elastically compressing the elastic member 186 or receiving the elastic restoring force of the elastic member 186 in the accommodating portion 185. [

The connection wire 188 of the object sensing unit 180 is electrically connected to a control box for converting the contact information into an electric signal and controlling the rotation of the driving motor 124.

The dislocation screen 130 and the body 154 are moved in the direction toward the main screen 120 side due to a rise in the water pressure or a rise in the speed of the water flow, The sensor unit (not shown) senses a touch signal when it contacts the contact unit 181 of the sensing unit 180 and slides.

The disposition screen 130 is formed such that the sensing bar 133 is formed horizontally on the upper side of the main screen 120 and the sensing bar 133 is moved in the direction of approaching the dislocation screen 130 to the main screen 120 side When the distance between the sensing bar 133 and the object sensing unit 180 is reduced to a preset distance range, the distance is reduced.

Here, the object sensing unit 180 is installed on the inner surface of the frame 110 at the same height as the sensing bar 133 described above.

The control box controls the drive motor 124 when the contact signal is received from the object detection unit 180 and does not operate the drive motor 124 when the contact signal is not received from the object detection unit 180 .

12, the fifth embodiment is similar to the second embodiment in that the load sensor unit 190 is a load cell type and includes a push button 192 which is in close contact with the lower surface of the sliding rail 157, A deformation rod 194 connected to the lower surface of the button 192 and adapted to detect a load of the electric potential screen 130 to which the deformation gauge for converting the deformation along the outer surface into electrical resistance is pressed against the pressing button 192, And a body case 196 to which the deforming rod 194 is fixed so as to deform the outer surface of the deforming rod 194 by a load applied to the button 192 side.

A strain gauge (not shown) refers to a strain gauge applied to a load cell, which normally transforms the strain of the outer surface of the strain rod 194 into a change in electrical resistance.

The deforming rod 194 transmits the signal to the control box which controls the rotation of the driving motor 124 when the displacing screen 130 is moved toward the main screen 120 due to the pressure rise.

When the displacement screen 130 moves in a direction toward the main screen 120 due to the pressure of the water pressure and the speed of the water flow, the control box controls the degree of the load of the electric potential screen 130 from the load sensor unit 190, Signal, and controls the rotation of the driving motor 124.

The control box activates the drive motor 124 when the load signal corresponding to the weight of the potential screen 130 is received from the load sensor unit 190. When the load signal is not received from the load sensor unit 190, (124) is not operated.
