Typically, a rotary vibration isolator is a main frame (1), a drive sprocket (2), a chain (3) as a basic configuration. ), and a vibration suppression unit 4.

The main frame 1 is a frame of a vibration damper, and is installed in a waterway 10 of various repair facilities including a river in a form intersecting with a water current in a vertical direction.

In order to install a vibration damper, concrete walls are usually formed on both sides of the waterway 10, and the main frame 1 is installed between them, and the water flowing along the waterway 10 passes through it and flows in with it to solve various problems. Filters out possible impurities.

In the present invention, similarly, a plurality of diaphragms 111 are formed in the vertical direction at a set interval as in a conventional vibration damper to block impurities, and sweep the impurities through a rake 41 that moves up and down the front of the Removal and transfer work is done.

In addition, the main frame 1 may be formed to reach the bottom of the channel so as to cover the entire channel, but it is difficult to configure the main frame 1 to the bottom of the channel. In order to open the water channel by lifting (1) upward, a separate auxiliary screen 12 installed on the bottom of the water channel is generally installed below the main frame 1.

In addition, guide rails 13 are formed on both sides of the main frame 1 to prevent separation of the vibration suppression unit 4 and to induce movement so that the vibration suppression unit 4 continuously rotates in the vertical direction.

That is, guide rails 13 in the vertical direction are formed on both sides of the main frame 1, and each guide rail 13 forms an annular shape such as a conveyor and moves along the guide rail 13, and the driving sprocket at the top A chain (3) rotating through (2) is installed.

The chain (3) is a known power transmission means in which links are continuously connected in the form of sharing a link with through holes formed at both ends and a pin installed to support through the two links in a state in which one through hole overlaps to be.

Since this chain 3 is a well-known configuration, some are omitted in the accompanying drawings to facilitate identification of other major configurations.

A drive shaft 14 is installed on the upper side of the main frame 1 in a lateral direction, and a drive sprocket 2 is installed at both ends of the drive shaft 14 to rotate while the chain 3 is wound. .

The driving sprocket (2) is a circular tooth, and protrusions (21) and support grooves (22) are alternately formed toward the outer periphery, and the protrusions (21) are rotated in a form that is inserted between the pins of the chain (3). As a result, the chain 3 rotates.

At this time, at the bottom of the guide rail 13, the guide rail 13 is configured with a curved surface or a driven sprocket that rotates without power for smooth rotation of the chain, and the driving sprocket (2) is located above the main frame (1). ) Is provided with a drive motor 30 that is mechanically connected to the drive shaft 14 for rotation.

The vibration suppression unit 4 crosses the front surface of the main frame 1 and has both ends coupled to the chains 3 on both sides, respectively, and has a protrusion inserted between the diaphragms 111 so that the main screen 11 It includes a rake 41 for sweeping up contaminants filtered on the front side, and continuously rotates the front of the main screen 11 from the lower side to the upper side through the rotation of the chain 3.

After the rake 41 is transferred to the upper side of the main frame 1 by removing impurities on the front of the main screen, it rotates along the driving sprocket 2 and rotates the rear side of the main screen 11 from the top to the bottom. .

In addition, contaminants caught by the rake 41 and transported upward are buckets provided on the lower side by their own weight as the chain 3 coupled to the vibration suppression unit 4 rotates downward along the driving sprocket 2 The impurities that are dropped to (20) and collected in this way are transported through means such as conveyors and disposed of.

3 is a side cross-sectional view showing the main screen structure of a conventional vibration damper.

As mentioned above, in a conventional vibration isolator, the main screen consists of a plurality of partitions formed vertically at a set interval, and a fixed frame for firmly fixing these plurality of partitions to the main frame frame corresponding to the height of the vibration isolator is provided. Are connected to the rear side. Such a fixed frame is typically composed of an H-beam crossing the main screen left and right so as to have sufficient strength for elements such as hydraulic pressure.

However, in the case of the conventional fixed frame of this structure, it acts as a factor that creates resistance to the water flow passing between the partitions, reducing the flow velocity, causing congestion of small impurities, and in addition to this phenomenon, it is easy to catch the impurities passing between the partitions. As a structure, there was a problem of accumulating impurities of various types and sizes, such as straw, twigs, and fine trees, being caught between the partitions and the fixed frame supporting the partitions.

4 is a side cross-sectional view showing a main screen structure according to an embodiment of the present invention, and FIG. 5 is a partial perspective view showing a shape of a fixing frame according to an embodiment of the present invention.

As a core structure of the present invention for solving the problems of the conventional main screen structure mentioned above, the fixing frame 113 that is in contact with and supports the rear surface of the plurality of partition plates 111 formed in the vertical direction at a set interval is side The center of the cross section has a shape that protrudes forward, and the upper and lower sides are inclined rearward from the protruding middle part, and the flow of water is guided to the upper and lower sides, reducing resistance and flow rate drop, while allowing small impurities to flow easily. do.

In addition, the fixing frame 113 and the diaphragm 111 are integrated, so that the rear side of the diaphragm 111 is partially inserted into the front of the fixing frame 113 so as to prevent impurities from being pinched therebetween. A plurality of insertion portions 114 are formed to have a.

The fixed frame 113 may be configured in various forms, but the present invention proposes two methods as a preferred embodiment.

First, in the first embodiment, the fixing frame is provided with a connecting plate 116 vertically connecting a pair of parallel plates 115 formed in a vertical direction as shown in FIGS. Consists of

At this time, the parallel plate located in the front has a first bent part 118 with a cross section protruding to the center, and a second bent part protruding so that the upper and lower ends are horizontally respectively rearward around the first bent part 118 (119) is formed to direct the water flow upward and downward. Similarly, in the first bent part 118, an insertion part 114 into which the rear side of the diaphragm 111 can be partially inserted is formed at the same distance as the diaphragm 111, so that the diaphragm 111 and the fixing frame 113 The combination of

6 is a side cross-sectional view showing a main screen structure according to a second embodiment of the present invention, and FIG. 7 is a partial perspective view showing a shape of a fixing frame according to a second embodiment of the present invention.

In addition, the second embodiment of the present invention is similar in that the flow of water is divided up and down through the first bent portion 118 and the second bent portion 119 of the same shape, but a separate bent member 117 is provided. do.

Specifically, in the second embodiment of the present invention, the fixing frame 113 is provided with a connecting plate 116 vertically connecting a pair of parallel plates 115 formed in a horizontal direction, so that the cross section is in the form of'工'. Is composed. That is, the above-mentioned conventional or fixed frame of the first embodiment is rotated by 90 degrees.

At this time, the bending member 117 is coupled to the front of the fixing frame, and the bending member 117 is specifically projected so that the first bent portion 118 with a center protruding toward the front and the upper and lower ends are respectively horizontal to the rear. The second bent portion 119 is formed, and the upper and lower ends of the bending member 117 are coupled to the upper connection plate and the lower connection plate, respectively. The bending member 117 and the fixing frame 113 may be coupled through a bolt (B) or the like, and the head of the bolt (B) may be depressed toward the bending member 117 to reduce water resistance.

8 is a cross-sectional view showing the shape of a diaphragm according to a third embodiment of the present invention.

In general, the diaphragm of the vibration isolator screen is constructed using a straight iron plate, and the spacing is generally the same before and after. In this form, if the size of the impurities pushed in is similar to the spacing between the diaphragms, the impurities (T) enter between the diaphragms, and a change in the posture of the impurities or when the size of the impurities is large, a jamming phenomenon occurs. It is pinched by force, which not only resists the flow of water, but also promotes the stagnation and accumulation of foreign substances flowing thereafter.

In order to prevent such a phenomenon, in the present invention, protrusions 112 protruding left and right to have a streamlined cross section are formed at the front end of the diaphragm 111 constituting the main screen 11 to partially narrow the gap.

This is a structure that substantially reduces the entrance side of the gap between the diaphragms 111, and primarily limits the size of the impurities flowing into the space between the diaphragms 111 so that the impurities are better filtered through the main screen 11 And, as mentioned above, even if an impurity having a size similar to the distance between the diaphragms 111 enters between the diaphragms, the gap capable of flowing between the diaphragms 111 is secured, so that it can be easily separated without pinching. In the third embodiment of the present invention, the protrusion 112 is integrated with the diaphragm 111 to be manufactured.

9 is a cross-sectional view showing the shape of a diaphragm according to the fourth embodiment of the present invention, and its practical form and function are the same as those of the third embodiment. However, in the third embodiment, the protrusion is formed when the diaphragm is manufactured, but in the fourth embodiment, a separate member serving as the protrusion in the third embodiment can be coupled to a general diaphragm without a protrusion as in the prior art. And the protrusion with a'C' shape at the rear end can be inserted into the front end of the diaphragm and combined through bolts (B) at the top and bottom of the diaphragm to prevent separation.

10 is a side cross-sectional view showing the structure of a rake according to the fifth embodiment of the present invention.

It is possible to drastically reduce the phenomenon that impurities are caught on the fixing frame while greatly reducing the resistance through the fixing frame 113 as in the first and second embodiments mentioned above, but as various types of foreign substances such as tree branches and various wastes flow in. The possibility that they get caught in the fixed frame 113 cannot be excluded at all.

To prevent this, a scraper 42 is installed in the selected vibration suppression unit among a plurality of vibration suppression units 4 that protrude rearward so as to contact the front surface of the fixing frame 113 to sweep away foreign substances caught in the fixing frame 113 Can be.

The scraper 42 is a metal bar that sweeps up and removes foreign substances caught in the fixing frame 113, and is hinged to the rear of the rake 41 so as to rotate in the vertical direction, but is in a state perpendicular to the transport direction of the rake 41 It is configured to contact the front surface of the fixed frame 113, that is, the portion of the first bent portion 118, and maintains a state perpendicular to the transport direction of the rake 41 through an elastic means such as a spring. (41) is raised and the scraper 42 is in contact with the fixed frame 113 and after some rotation to the lower side, it is preferable to be configured to return to the original position.

The rights of the present invention are not limited to the embodiments described above, but are defined by what is described in the claims, and that a person having ordinary knowledge in the field of the present invention can make various modifications and adaptations within the scope of the rights described in the claims. It is self-evident.
