Abstract

The present invention relates to a vertical multi-level sluice, the sluice produced in multiple stages depending on the depth? In order to prevent damage caused by strong winds, to effectively utilize the function of the water gate, and to facilitate installation and repair, the water gate manufactured to a certain standard can block the flow of algae at a predetermined height in the water gate groove installed in the piers. Minimizes the effects of strong winds by opening and closing vertically using power tied with wires or threaded shafts, and lifting the upright water gate, which is closed when opening the water gate, with the water chin to be stacked under the water tower. It controls the amount of water passing through the opening height, protects the aberration from high waves, and also uses it as a water barrier wall when reinforcing work between piers.

Description

Multi-step Floodgate for full stream

The present invention relates to a multi-level sluice that is installed in a deep water channel. More specifically, a plurality of sluices manufactured to a certain standard are bound in multiple stages according to the depth, and the lower sluice is composed of a wire or a screw shaft. It is a multi-level gate that closes in sequence in the order in which it is closed with the device, and the gates attached to each gate are raised under the hydro tower when it is fully opened by lifting the closed gate.

In tidal power generation, sluices have a variety of functions and roles, including installation and lifting of aberrations, generator utilization rates to maintain average power generation, control of generation and free fall, additional intake and drainage, and protection of aberrations from waves. In addition, the water gate is used as a water barrier means for drainage so as to attach the guide plate of the wing aberration and when installing the midway connecting the aberration base and the pier in the underwater installation method of the piers omitting the water barrier.

When a floodgate is built on a levee to control the floodwater level in the river, the floodwater can be adjusted from the bottom to the highest level according to the inflow from the upstream, so the floodwater is controlled and the water is stored in large quantities.

In order to achieve the above function, the water gate must be opened and closed vertically from the bottom to the water in the depth of water, so the water tower must be raised by the height when the water gate is opened.

However, the height of several tens of meters must be made with a single gate and it is difficult to withstand the water pressure, but when the gate is too high, the gate may be broken by strong winds or the power plant structure may collapse.

Therefore, when the gate is completely closed and opened up to the bottom, a multi-level gate is needed to ensure that the top of the gate does not rise more than 10-15 meters above the surface.

Therefore, it is intended to prevent damage caused by strong winds, to fully function, and to be easy to install and repair by installing a plurality of sluices made to a certain standard in multiple stages according to the water depth so as not to rise more than 10-15 m when fully opened.

In order to achieve the above object, depending on the depth of the water gate according to the depth to each of the lower height to each independent height to make a plurality of sluice grooves 88 in the pier 65, casing, and manufactured to a certain standard to make both sides (兩 面) Finishing with panels and attaching the pulleys to the four corners to reduce friction and inserting a plurality of sluice gates 85 attached to the top and bottom or slugging head 96 at the top or bottom of the sluice tower 81 The power unit and the lower gate 85 are bound with a wire or threaded shaft to open and close.

Each gate (85) is divided into a sluice gate (88) with a septum to make an independent track, or binds to the gate (85) next to the hydrological holder 101, depending on the direction of water flow Prevent gaps between hydrologic gates.

Between the sluice groove 88 and the sluice holder 101 and on the sluice gate? Attaching a gasket (gasket) at the bottom to block the leakage, reinforce the skeleton to withstand the water pressure depending on the closing depth, light weight when opening and closing the foam urethane between the hydrologic skeleton.

If the buoyancy is large enough to allow the water gate to float on the water, the vertical screw-shaft 27a, which is fixed to the lock tower and the fixing nut 115a attached to the lower gate 85, respectively, is fixed to the gate tower and the base of the gate. 106 to slowly open and close the water gate (85).

Multiple water gates can be installed in multiple stages to block waterways regardless of depth, and only partially open the water to control the amount of passage.When fully opened, all the multi-level gates gather under the water tower to avoid the damage of strong winds and withstand strong waves. have.

With reference to the drawings will be described in detail with respect to the multi-stage sluice according to a preferred embodiment of the present invention.

As shown in FIG. 1, the sluice groove 88 is cascaded to the pier 65 so as to descend to the depth at which the sluice 85 is closed step by step as shown in FIG. 1. The sluice groove 88 is divided into a chin (gravity) for each sluice as shown in FIG. 1 or binds to the sluice next to the sluice holder 101 as shown in FIG. 2.

The former has the advantage that the hydraulic pressure rises and falls along the magnetic track for each gate regardless of which pressure is applied, but if the gate groove 88 is not made of steel, the gap between the upper and lower gates can be increased due to the thickness of the jaw, and the latter can have a large amount of leakage. Although the gap is small, the amount of leakage is small, but the top gate is pulled out due to water pressure depending on the direction of water flow.

Attach one to the top or the bottom of each of the sluice (96) at the top or bottom of each gate (85) or attached to the top and bottom of the sluice (85) located in the middle as shown in FIG. When it stops and opens, the lower sluice 96 pushes up the immediate hydrology so that all the hydrology 85 gathers under the hydrostation tower 81.

The deeper the water, the higher the water pressure, so the water gate (85) located at the bottom strengthens the hydrologic skeleton and closes both sides with panels to prevent water leakage between the skeletons. A rubber gasket is attached to the side, and the inside of the water gate 85 is filled with foamed urethane or sealed to lighten the weight by buoyancy and increase the rust prevention effect of the water skeleton. In particular, when the water gate is used frequently, such as tidal power plants, the pulleys are attached to the four corners of the water gate because the friction between the water gate and the gate and the water gate and the gate of the gate 88 may not be severe and the opening and closing operation may not be smooth.

The device for opening and closing the gate is a gate passing through the gate between the two multi-stage pulleys respectively fixed to the gate and the lower gate, or through the nut 115 secured to the lower gate 85 as shown in Figure 4 and the hydrologic base The water type 85 is opened and closed by rotating a screw-type vertical shaft 27a having a driving unit fixed to 37a with a reduction motor. The latter is advantageous when the water gate is buoyant enough to float on the surface of the water.

Assemble the next hydrology by assembling the hydrologic foundation (37a) made of reinforced concrete, the lower hydrology (85), and the screw shaft to fit into the hydrology groove (88). Insert it down into the sluice groove 88 to the depth that can be assembled and assemble it to the last sluice.

When draining to work inside both gates, a waterproof curtain can be installed on the gate to completely prevent leakage and flooding.
