1 to 7, a rotary damper 10 according to an embodiment of the present invention collects contaminants flowing along water flowing in a river or a river channel. The rotary damper 10 includes a body 20, a main screen 30, a rake 100, and a reverse rotation operation unit 200.

The body 20 forms an outer shape of the rotary damper 10 and is installed inside the flow path block 2. [ The flow path block 2 is a dam provided along both sides of the waterway.

Particularly, the body 20 is installed so as to be spaced from the bottom surface of the water channel or the bottom surface of the flow path block 2 by a predetermined distance. This is to prevent the sub rake 130 of the rake 100, which is installed to be infinitely rotated inside the body 20, from being caught or interfered with the bottom surface of the river.

In addition, the body 20 serves to connect or support the main screen 30, the rake 100, and the like.

The body 20 can be deformed into various shapes, which are shown in a generally box-like shape for convenience. Of course, the body 20 can be made of various materials.

The main screen 30 is provided at an inner lower portion of the body 20 to filter contaminants flowing therethrough. The main screen 30 is formed so as to allow water (wastewater) to pass therethrough and to filter contaminants. Of course, the main screen 30 is made of various materials and is connected to the body 20 in various ways such as welding.

In particular, the main screen 30 includes a transverse bar 32 that restrains the barrel 32 and the barrel 32 disposed side by side.

The vertical bars 32 are arranged in a direction perpendicular to the transport direction of the rake 100. Thus, the main rake 120 of the rake 100 is moved along the adjacent vertical bars 120. Of course, the vertical bar 32 can be deformed into various shapes.

In addition, the transverse bar 34 serves to maintain the distance between the vertical bars 32 by connecting and restraining the vertical bar 32 with each other.

At this time, the transverse bar 34 connects the lower side as much as possible in the thickness direction of the vertical bar 32 so that the main rake 120 can be moved while inserted between the vertical bars 32.

Both sides of each of the transverse bars 34 are fixedly connected to the body 20 so that the main screen 30 can be fixed to the body 20.

The rake 100 is provided on the body 20 in an endless rotation along the axial direction, and serves to remove the contaminants stuck in the main screen 30. [

Particularly, the rake 100 moves from the lower front to the upper side of the main screen 30 and is connected to the body 20 so as to rotate along the elliptical trajectory with respect to the main screen 30 in an endless track manner.

For example, the sprocket wheel 22 is rotatably mounted on the body 20 so as to face both the upper side and the lower side or the upper side, the body 20 is provided with the chain 24 on both sides along the axial direction, Each of the chains 24 is infinitely rotated by the sprocket wheel 22. The rake 100 is connected to the chain 24 on both sides.

At least one of the pair of sprocket wheels 22 facing the left and right direction of the body 20 is forcibly rotated by the operation motor 26. Therefore, the chain 24 and the rake 100 rotate infinitely in the order of the front lower portion, the front upper portion, the rear upper portion and the rear lower portion of the main screen 30 in order.

That is, the rake 100 rotates in an up-and-down direction on the main screen 30 by the chain 24 in an endless track manner and serves to remove the obstacles stuck in the main screen 30.

The rake 100 may include a frame 110, a main rake 120, and a sub-rake 130.

The frame 110 is connected to the corresponding chain 24 on both sides. At this time, the frame 110 may be connected to the chain 24 in various ways such as a pin coupling. Further, the frame 110 can be deformed into various shapes.

The main rake 120 together with the frame 110 moves upward in the lower portion of the front side of the main screen 30 and scrape up the obstacles inserted between the vertical bars 32 of the main screen 30 And is spaced apart from the frame 110 by an interval set along the axial direction. In addition, the main rake 120 is made separately from the frame 110 so as not to be constrained to each other.

Accordingly, a plurality of main rake 120 are provided.

At this time, the main rake 120 has a length that does not strike the transverse bar 34. Of course, the main rake 120 can be modified into various shapes.

In addition, each of the plurality of main rake members 120 should be assembled so as to be supported so as not to fall in a lateral direction between the lid 140 and the frame 110 bound together.

Thus, each of the main rake 120 is recessed at the lower side so as to be seated on one side of the frame 110 on a one-to-one basis. That is, since the lower seating groove 122 receives a portion of the frame 110, the corresponding portion of the main rake 120 corresponding to the inner side surface of the lower seating groove 122 increases the contact area with the frame 110 So that the main rake 120 is stably installed in the frame 110.

In addition, the frame 110 is recessed to fit the main rake 120 along the axial direction to position the main rake 120. That is, the main rake 120 is easily positioned by being inserted one-to-one into the recessed grooves 112, and is supported inside the recessed grooves 112 so as not to fall in the lateral direction. At this time, the concave grooves 112 may be formed to be depressed in the center direction from both edges with respect to the central axis corresponding to the axial direction of the frame 110, or may be recessed in the center direction from either one of the edges.

Particularly, a portion where the lower seating groove 122 of the main rake 120 is formed is to be mounted in the concave groove 112 of the frame 110.

In addition, the main rake 120 is formed with an upper seating groove 124 on the upper side to accommodate the edge of the lid 140.

The upper seating groove 124 is formed on the upper side of the main rake 120 so as to be deeper than the thickness of the lid 140.

The sub rake 130 is formed in each of the main rake 120 in the axial direction so as to scrape off the contaminants deposited on the bottom of the stream and the contaminants caught on the auxiliary screen 50.

In addition, the sub-rake 130 may be integrated with the main rake 120. Thus, the sub-rake 130 can move with the frame 110 from the lower rear side to the rear upper side of the auxiliary screen 50, thereby stably scraping the obstacles hanging on the lower front side of the auxiliary screen 50.

At this time, the length of the sub raker 130 is not limited.

The lid 140 is coupled to the frame 110 in a state of being in contact with the upper side of the main rake 120 and the sub rake 130 supported by the frame 110 so that the main rake 120 and the sub rake 130 It maintains alignment and fixes.

At this time, the lid 140 is detachably restrained to the frame 110 by the fastening member 142. Here, the fastening member 142 is a mechanical fastening element such as a bolt.

Accordingly, since only the main rake 120 and the sub-rake 130 that are damaged or deformed among the plurality of main rake 120 can be replaced, the maintenance cost of the rake 100 is reduced.

Particularly, the lid 140 is formed by extending a bending portion 144 which is bent on both sides or one side along the axial direction and extends between the bending portions 144 to support both sides of each of the main rake 120 Thereby forming a groove 145.

When the main rake 120 scrapes the obstacles on the main screen 30 and the sub rake 130 scrapes the obstacles on the auxiliary screen 50, ) To the worksite. In this case, the workplace is contaminated.

Thus, the body 20 is provided with an apron 40 for preventing the descent of river water and contaminants that are moved upward by the rake 100. That is, both sides of the apron 40 are fixed by bolting, welding, or the like to the inner surface of the upper portion of the opposed body 20.

Accordingly, the contaminants and the river water that are caught by the main rake 120 and the sub rake 130 are dropped to the set position or fall down along the apron 40 to the river.

Of course, the material and the shape of the apron 40 are not limited.

The cover 140 is coupled to the frame 110 in a state of being in contact with the upper side of the main rake 120 supported by the frame 110 so that each of the main rake 120, It plays a role of fixing.

At this time, the lid 140 is detachably restrained to the frame 110 by the fastening member 142. Here, the fastening member 142 is a mechanical fastening element such as a bolt.

Further, the obstacle caught by the rake 100 moves downward along the body 20 and falls down at the time of descending to change the direction. Therefore, a collection box (not shown) is provided at the corresponding position. A collection box (not shown) serves to accommodate falling objects.

Meanwhile, the main rake 120 has a remover 150 at an end or an edge thereof. Since the remover 150 is disposed over the widest range between the vertical bars 32, the remover 150 serves to pull out elongated contaminants or foreign substances such as vinyl or wires sandwiched between the vertical bars 32. At this time, since the vertical bar 32 is connected to the transverse bar 34 and restrained, the remover 150 is made of a resin material so that a predetermined deformation can be generated when the transverse bar 34 hits the transverse bar 34. Of course, the remover 150 can be modified into a variety of materials and various shapes.

In particular, since the remover 150 is moved in contact with or close to the neighboring vertical bar 32, the area of contact between the remover 150 and an elongated obstacle hung on the main screen 30 is increased, so that the contaminant can be scraped Can be removed. At this time, the remover 150 may be rough or uneven so as to prevent the collection failure due to slippage in a state where the long, light or light impurities are in contact with each other.

The remover 150 is coupled to the main rake 120 by a binding member 152 to be detachable from the main rake 120 when breakage or deformation occurs. Here, the binding member 152 is a bolt or a screw.

 On the other hand, an auxiliary screen 50 may be provided on the bottom of the river. Particularly, the auxiliary screen 50 is disposed on the front side of the body 20 or the main screen 30 with respect to the flow direction of the river water, and serves to filter off the contaminants flowing out to the lower side of the main screen 30.

That is, the auxiliary screen 50 is fixed to the bottom surface of the flow path block and functions to filter the obstacles to pass between the lower side of the body 20 and the bottom surface of the flow path block.

In particular, the auxiliary screen 50 may include a base member 52, an auxiliary screen member 54 and a revolving tube member 56.

The base member 52 can be formed in a plate shape fixed to the bottom surface of the flow path block and serves to support the auxiliary screen member 54.

The auxiliary screen member 54 is connected to the base member 52 so as to extend upwardly to filter the contaminants to be passed to the lower side of the main screen 30. At this time, the auxiliary screen member 54 can be formed in various shapes, and the main rake 120 of the rake 100 can remove the contaminants trapped in the auxiliary screen member 54.

On the other hand, the auxiliary screen member 54 is rotatable with respect to the base member 52 by one connecting pipe member 56. That is, the auxiliary screen member 54 extends from the peripheral surface of the rotary pipe member 56, respectively, and the rotary pipe member 56 is rotatably connected to the base member 52 in the circumferential direction.

The auxiliary screen member 54 can be returned to the initial position when the pushing force of the sub rake 130 is removed after the auxiliary screen member 54 is rotated in the forward direction by the pushing force of the sub rake 130. This is because, when the auxiliary screen member 54 rotates in all directions, a gap is widely formed between the main screen 30 and the front side of the main screen 30, and the contaminants flow out through the screen.

The auxiliary screen member 54 is rotatably connected to the base member 210 by the rotary pipe member 56 and is supported on the floor surface of the channel block so as to be rotated in accordance with whether the rake 100 is pushed or not. The member 60 is connected.

That is, one side of the tension member (60) is rotatably provided on the bottom surface of the channel block, and the other side of the tension member (60) elastically supports the auxiliary screen member (54).

Thus, the auxiliary screen member 54 is brought into a standing state before the external force is applied and after the external force is removed by the supporting force of the tension member 60.

When the sub-rake 130 pushes the auxiliary screen member 54, the tension member 60 is compressed to generate an elastic restoring force. Here, the tension member 60 may be variously applied to a shock absorber or a coil spring.

Particularly, the number of the tension members 60 can be varied depending on the number and size of the auxiliary rakoe members 54.

The auxiliary screen member 54 is returned to its original position by the action of the elastic restoring force of the tension member 60 after the rake 100 is moved after the auxiliary screen member 54 is bent by the pushing force of the rake 100 moved in the forward direction. At this time, as the auxiliary screen member 54 is rotatable, the auxiliary screen member 54 and the main screen 30 can be disposed as close as possible. Particularly, the auxiliary screen member 54 returned to the home position is disposed adjacent to the main screen 30, so that the contaminants flow into the space between the main screen 30 and the auxiliary screen member 54, Leakage is prevented as much as possible.

When the rake 100 is moved in the reverse direction opposite to the forward direction in which the rake 100 scraped the obstacle caught on the main screen 30, the backward turning operation unit 200 is operated by turning the auxiliary screen 50 to the sub- 130 (interference) between the input signal and the output signal.

Here, the reverse rotation operation unit 200 includes a link bar 210 and an operation member 220.

The link bar 210 is connected to the rotary pipe member 56 or the auxiliary screen member 54.

The operation member 220 is installed on the upper side or the bank of the flow path block 2 and is linearly reciprocated to force the rotary pipe member 56 to rotate by pushing or pulling the link bar 210. For the sake of convenience, it is assumed that the operating member 220 is a cylinder.

The link bar 210 is connected to the first link 21 and is fixed to the circumferential surface of the rotary pipe member 56. The first link 212 extends from the operating member 220 toward the bottom of the river, And a second link 214 connected thereto.

When the operating member 220 pushes the first link 212 in the downward direction, the first link 212 pushes the second link 214 toward the lower side while pushing one side of the second linked link 214, And pulls it to the rear side along the direction. As a result, the other side of the second link 214 rotates the rotary pipe member 56 in one direction. Therefore, the rotary pipe member 56 is rotated in one direction, so that the distance between the auxiliary screen member 54 and the main screen 30 is further widened.

Conversely, when the operating member 220 pulls the first link 212 to the initial position, the first link 212 pulls the second link 214 in the axial direction while pulling one side of the second link 214 to the initial position To the front side. As a result, the other side of the second link 214 rotates the rotary pipe member 56 in the other direction. Thus, the revolving pipe member 56 is rotated in the other direction, and the auxiliary screen member 54 is returned to maintain the distance from the main screen 30 to the initial state.

Of course, the link bar 210 is variously applicable.

On the other hand, the body 20 forms a guide rail 21 on the inner side facing the chain 24 to accommodate the chain 24.

The chain 24 has a wall member 28 that is higher than the height of the guide rail 21 in order to block the entry of foreign matter into the guide rail 21.

That is, the guide rail 21 is formed to cover the whole or a part of the inner side surface of the body 20 to receive the chain 24, and the chain 24 includes a pair of side wall members 28 for blocking the open side of the guide rail 21, .

As a result, foreign matter does not flow into the open side of the guide rail 21 due to the rear wall member 28, so that the resistance due to the movement of the chain 24 does not significantly increase.

Of course, the rear wall member 28 may be formed in various shapes and may be fixedly installed in various ways at various positions of the chain 24.

In other words, the body 20 and the guide rail 21 are formed so that the inside facing to receive the chain 24 to which the frame 110 of the rake is connected is opened. At this time, when the contaminant is to be introduced into the chain 24 through the open side of the body 20 and the guide rail 21, the rear wall member 28 prevents the entry of the contaminants.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
