Description

Screen type of rotary vibration damper {Rotary type Screen apparatus}

The present invention relates to a facility installed on the sea to protect the algae power plant, and more specifically, to a facility for protecting the algae power generation facilities from collisions or sticking of floating contaminants having various volumes and masses in the sea where fast algae flows.

The present invention relates to a screen device of a rotary vibration damper that is installed to remove a float in front of an algae power generation facility.

In general, tidal power generation is similar to hydroelectric power generation by generating tidal dams within the tidal tidal flats to block seawater distribution and using water level differences inside and outside the dams caused by tidal tidal currents.

However, tidal power generation uses the water level difference inside and outside the dam (embankment), so there is a problem in that it is necessary to form a seawall and entail environmental effects.

In order to improve the shortcomings of tidal power generation, recent attempts have been made to generate power using algae, which is evaluated as an environment-friendly power generation method than tidal power generation.

Algae power generation is considered to be more environmentally friendly than tidal power generation, because it is installed without dams and is installed directly in the waterway where strong flow rates are generated by algae.

On the other hand, algae power generation facilities are installed on the sea near the land and floating garbage such as horse waste, nets, buoys, etc. from household wastes such as home appliances and wood, etc. Since the inflow of is expected, it is necessary to install a protection facility to protect the power generation facilities of the power plant to remove the suspended solids continuously.

These floats can be divided into cases that can give a big impact on the equipment and cases that can be stuck or wound on the equipment to reduce the performance of the equipment, in order to block and remove the inflow into the power generation equipment. A device, commonly called a vibration damper, is installed at the inlet of a power generation facility through which algae flows.

Generally, the vibration damper is installed in the drainage pump station, water supply intake, related water channel, sewage treatment plant and dam in the lower part of the water surface to filter and remove the floating material moving with the water through the screen. A rotary damper device of typical construction is disclosed.

6 and 7, the vibration damper main body (1) is installed to be inclined almost at right angles to the water flow as shown in FIGS. 6 and 7 and filters the suspended matter of the water stream with the screen (11) formed on the front surface (1). ), A rolling chain 2 which is continuously and repeatedly moved by the driving force of the driving motor 13 along the guide rails 12 formed on both sides of the vibration damping base body 1, and the rolling chain 2 at regular intervals. A plurality of rakes 2 installed to be connected to each other and moving together with the rolling chain 2 to lift and remove the floating material caught in the screen 11 while moving upward from the bottom surface under water to the top, and the vibration damper; And a discharge conveyor (4) installed on the upper rear side of the main body (1) to receive the suspended matter lifted and dropped by the rake (2) and discharge it to the outside of the apparatus. The rolling chain 2 is configured to circulate along an annular trajectory by the guide rail 12 of the damping basic body 1, and the rolling chain 2 meshes with the driving sprocket 14 to drive the sprocket 14. The driving sprocket 14 is configured to be rotated by the driving force of the driving motor 13, so that a plurality of rakes 2 connected to the rolling chain 2 are rolled chain 2. And along with the vibration damping base (1) is to lift the float while being configured to discharge to the outside through the conveyor (4).

Here, as shown in detail in FIG. 8, the screen device 10 is provided such that the screen blades 11 having a long vertical length are arranged side by side at regular intervals, and the screen blades 11 are arranged side by side. In order to retain the back surface thereof, a plurality of support plates 20 and 30 are bolted through welding or other members at regular intervals up and down.

Accordingly, through the open space between the adjacent screen blade 11 and the screen blade 11, the flow of water flows out by the suction pressure of the pump operated at the rear of the apparatus, and the various kinds of water flowing along the flow of the water flow. Among the floats, the floats larger than the interval between the screen blades 11 are lifted up by the rake 2 which is caught by the screen device 10 and are discharged to the outside.

However, since the screen device 10 has a long length in the vertical direction and a wide width to be installed, the support device 20 or 30 is required to support the heavy load, such as a large tree or an abandoned refrigerator. There is a possibility that the screen unit 10 may be distorted when they flow and collide with water flow, and the screen unit 10 may be distorted. When the screen unit is distorted, the gap between the screen blades 11 is narrowed or is deformed in a curved path. May be impossible to move. In view of this, the support plates 20 and 30 have to be made large in order to enhance the strength of the screen device.

However, such a screen device does not have a big problem when installed in a simple drainage channel where only floating matters are important. However, in the case of a tidal power plant or a large drainage pump station that needs to drain a large amount of water promptly during heavy rains, a support plate may be used. Larger formation can cause big problems.

That is, in the algae power plant, the maintenance of the rapid flow rate of the algae is very important for the power generation efficiency, but when the support plates 20 and 30 are large or installed, they act as a resistance to the flow of the algae, thereby lowering the flow rate, thereby reducing the power generation efficiency. In addition, in the case of the drainage pumping station, water must be drained quickly in order to avoid flood or flooding damage due to intensive rainfall, but at this time, the support plate 20 and 30 causes the flow rate and flow rate to drop so that the drainage is delayed. There is a risk of flood damage.

As such, in the case of tidal power generation, the vibration damper device is required to be very large, and thus it is difficult to meet the required strength and low resistance with the simple plate-shaped support plates 20 and 30, which should be reflected in the design of the screen device. The main point is to increase the supporting strength so as to function as a strength reinforcing member and at the same time reduce the water flow resistance.

Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide a screen device for a rotary vibration damper having a large support strength without disturbing the flow of algae.

The screen device for rotary vibration damper according to an embodiment of the present invention for achieving the above object is installed so that the screen blades of the long thin plate is arranged up and down side by side at a predetermined interval, the screen blades side by side spacing In the screen device to maintain a plurality of stages of the support plate is fixed to the front of the vibration damper at regular intervals up and down on the rear side of the back to maintain the filter to remove and remove the floating flow along the flow of algae, wherein A plurality of distribution holes for allowing the passage of algae is formed in the portions of the support plates exposed to the passage through the flow path between the screen blades.

In addition, according to the present invention, the support plate is characterized in that it is selected from flat plate, U-shape, L-shape, H-shape, square pipe, round pipe, I-shape.

In addition, according to the present invention, the support plate is selected from a four-pipe, U-shaped, H-type, characterized in that the distribution holes are formed through the front and rear vertical walls of the support plate.

In addition, according to the present invention, a hollow guide pipe is fitted and welded to the distribution hole penetrating the front and rear vertical walls of the support plate so that the algae is guided to flow backward through the hollow guide pipe.

According to the present invention, the screen blades are fixed and supported by using a strength reinforcing member having a wide top and bottom width or a very large cross section coefficient, so that it can be used for removing algae power and a large capacity drainage pump station with high flow rate. It is possible to form a hole to allow the passage of algae in the support plate to prevent the fall of the flow rate as much as possible is useful for improving the generation efficiency of the algae generator installed in the rear of the vibration damper and preventing flooding. In particular, quadruple pipes, which have been the most reliable in their support strength but have not been used for tidal power generation due to their high resistance to flow rates, can be used as strength reinforcing members by adopting tide through holes. Silver can be completely eliminated by the application of the guide pipe, which is particularly useful as a facility for algae power generation because it has a strength and prevents a drop in flow rate.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
