The vibration damper of the present invention has a simple operation in which the strength of removing impurities by the rake unit It is adjusted according to the site, and in particular, by using a single sensing unit, the overload generated by the plurality of rake units is integrated and managed, and the overload pattern is detected to improve the accuracy according to the emergency stop. 20), consisting of a rake portion 30 and the tension member 40 as the main components.

First, the screen 10 according to the present invention is supported by the frame 12 installed in the waterway and provided to filter out impurities. The frame 12 is installed opposite to each other on the water channel wall, and the screen 10 is supported by the frame. In the screen 10, a plurality of screen blades are arranged vertically (vertical) to filter out impurities that float down the waterway, and the filtered impurities are collected by a rake to be described later, loaded on a conveyor belt or bucket, and transferred to a treatment plant. do.

The support arm 20 according to the present invention is a member for stably supporting the rake part 30 to be described below, which is installed long in the horizontal direction so as to traverse the screen 10.

Both ends of the support arm (20) are connected to a pair of chains (22) and provided in plural so as to orbital movement with the chain (22), and the chain (22) is a rail provided on the pair of frames (12) And the sprocket is connected to the orbital motion, and any one sprocket is connected to the motor to transmit the driving force.

The rake unit 30 according to the present invention is arranged to be perpendicular to the screen 10 between the screens 10 and is configured to lift the impurities caught on the screen 10 upward.

More specifically, as shown in the enlargement of FIG. 1, the rake part 30 has a shaft pipe formed on the bottom surface and is fitted to the horizontal shaft 31 to rotate around the horizontal shaft 31 on the support arm 20, and at one end A rake blade 32 inserted between the screens 10 to remove impurities, and a hopper 34 exposed to the outside of the screen 10 to transport impurities caught in the screen 10 at the other end to the collected sieve are provided. .

Accordingly, the rake part 30 moves upward from the bottom of the screen 10 by the chain 22, and the rake blade 32 removes impurities collected in the screen 10, and the rake blade 32 The impurities removed by this move along the upper surface of the rake unit 30 and are collected in the hopper 34. At this time, the hopper 34 is bent upward at the end of the rake part 30 so that the impurities collected in the hopper 34 are not separated again.

The tension member 40 according to the present invention is installed to connect the support arm 20 and the rake part 30, and after the rake part 30 is caught by an impurity and rotated by an overload, the original position, that is, the screen 10 ) To return to the vertical state. Here, the rake part 30 is maintained in a horizontal state by the tension member 40.

3 is a sequence diagram showing the action of the rake portion and the tension member of the present invention, as shown, the tension member 40 is coupled to the rake portion 30 by a hinge 42a to enable a pivotal movement. The sleeve 42 and one end is coupled to the support arm 20 by a hinge 44a, and the other end is inserted through the sleeve 42, and the adjustment rod 44 to which the adjustment nut 45 is fastened. , Consisting of an elastic body 46 installed between the sleeve 42 and the adjustment nut 45.

Due to the above-described configuration, the sleeve 42 coupled to the rake part 30 rises while riding the control rod 44 when the rake part 30 is caught by an impurity and rotates due to an overload, and the elastic body 46 is compressed. When the overload applied to the rake part 30 is released, the elastic body 46 quickly returns to the original position of the rake part 30 by compression force.

Meanwhile, by varying the position of the adjustment nut 45 screwed to the end of the adjustment rod 44, the compressive strength of the elastic body 46 may be adjusted. Accordingly, the strength of removing impurities by the rake part 30 is customized to the site by a simple operation of adjusting the adjustment nut 45 of the tension member 40, that is, hard impurities including stones are the mainstream. The compressive strength of the elastic body 46 is relatively weakly controlled in the waterway, and the elastic body 46 is relatively strongly adjusted in the waterway where soft impurities including plant stems are the mainstream, preventing damage to the rake part 30 and removing impurities. Try to improve.

The vibration damper provided in the present invention is characterized in that a sensing unit 50 for detecting an overload of the rake unit 30 is configured.

One end is connected to (52a), the other end is connected to the frame (12), a rod rod (54c) provided to maintain the tension of the wire 52 by an elastic body (54b), and the wire is installed on the frame (12) (52) It consists of a sensor 54d that detects the movement of the rod rod 54c due to an increase in tension.

In this way, by using the sensing unit 50 of a simple structure installed on the upper frame 12, the overload generated by the plurality of rake units 30 can be integrated and managed, so that the failure rate is low and other maintenance costs are required for long-term operation. Greatly reduced.

Hereinafter, the operation of the vibration isolator will be described with reference to FIG. 4 showing an enlarged operation of the rake portion of the vibration damper.

When the rake part 30 is caught by an impurity and rotated due to an overload, the sensing piece 56 connected to the horizontal shaft 31 rotates together as shown in FIG. 4 to press the wire 52, and at this time, the wire 52 is pulled. The rod rod 54c of the sensor module 54 is moved linearly as much as the length of the loss, and touches the sensor 54d.

In addition, the signal touching the sensor 54d is detected by the control unit 58 as an overload of the rake unit 30 and stored in the memory and transmitted to the server (central control room, manager terminal, etc.) through the communication module to replace the screen 10, It triggers an alarm so that follow-up actions, including cleaning, can be quickly performed. On the other hand, the control unit 58 may be configured to execute an emergency stop mode in which the operation of removing impurities by the rake unit 30 is stopped when an overload of the rake unit 30 is detected.

In addition, the control unit 58 detects an overload pattern of the rake unit 30 detected through the sensor module 54. Here, the overload pattern of the rake unit 30 refers to a detection signal for detecting an overload of the rake unit 30 at a constant time period under the condition that the chain 22 is orbital at a constant speed.

And, when the number of times the overload pattern value of the rake unit 30 is repeated reaches the set value in the control unit 58, it is determined that impurities are stuck on the screen 10, and the emergency stop and emergency stop conditions of the rake unit 30 are sent to the server. It is provided to send out.

Accordingly, even if the control unit 58 receives the overload detection signal of the rake unit 30 once, it does not stop and repeats several times until the set value is reached in the control unit 58, and soft impurities including fruits and soil are caught. In addition to removing it, the rake unit 30 prevents an emergency stop malfunction due to a single impact, and when the number of repetitions set in the control unit 58 is exceeded, it is determined as a hard impurity such as a stone, and the rake unit 30 emergency stop and emergency As the stop situation is transmitted to the server, it is possible to prevent a decrease in the efficiency of removing impurities due to unnecessary stopping of the rake unit 30.
