Description

Gate built-in type aqueduct for tidal power embankment}

The present invention relates to a waterway installed in tidal power generators to connect the outer sea and George, and a water gate is installed inside the waterway, and the upper surface of the waterway before the watergate is curved, so that the cross section of the waterway is gradually increased. By forming a channel upper structure to be enlarged, it is possible to form a hydrology chamber in which the water gate is accommodated inside the upper structure.

In addition, the lower part of the hydrology room was provided with a blocking door that closes the hydrology room after the receipt of the hydrology door so that the normal waterway function can be ensured even during the inspection and repair work of the hydrology door.

Tidal power generation is a kind of artificial sea reservoir, which is a kind of artificial sea reservoir by building a dike on the coast where tidal tides are remarkable. It refers to the method of generating water by driving aberration in the process of draining from George to the open sea when the open sea is low.

In the aberration drive by seawater flow between George and the open sea, the method of operating the aberration when the inflow of the seawater into the George and the drainage to the open sea is called the double flow type, and the method of operating the aberration only in either the inflow or the drainage is called the single flow type. The operation of the aberration at the inflow during the inflow type is called the fall-off type.

In tidal power generation using such a dike, it is common to install a parabolic waterway for the additional discharge or inflow in the dike, in addition to the dike, in which the aberration is driven, an example of which is shown in FIG. It is.

FIG. 1 is a typical Venturi channel, which is installed across the seawall 50 and has a minimum channel cross-section at the installation site of the channel 10 on the end of the channel.

That is, the cross section of the channel from the inlet to the water gate 10 installation point in the drawing is reduced, and the water channel cross section is expanded again after passing the water gate 10 installation point.

When the conditions such as roughness and extension are the same, the water supply capacity of the channel can be said to be proportional to the cross-sectional area of the channel. It can be said to be advantageous.

Therefore, in order to secure the maximum water passing capacity of the waterway crossing the water repellent 50, it is advantageous to install a straight water channel as large as possible without a change in the cross-sectional cross-sectional area, but the size and stability of the water repellent 50, as well as increase in construction cost Because of the constraints, the appropriate size of the channel can be determined by considering the required water carrying capacity and other conditions.

As can be seen through FIG. 3, a cut-out part 25 is formed at the bottom of the hydrology chamber 23 inside the upper structure 20 to allow the gate 10 to enter and exit through the entrance part 25. In addition, since the storage space of the water gate 10 can be secured by forming the upper structure 20 by curving the bottom of the water channel in a plane, the water gate 10 is opened inside the water chamber 23 when the water gate 10 is opened. The upper slab 21 can be completely accommodated, and thus, the upper slab 21 can be smoothly formed without installing the watchtower structure exposed to the upper slab 21.

On the other hand, FIG. 4 is a configuration in which the hoisting chamber 22 is not formed at the upper side of the hydrological chamber 23, but at the side, so that the required upper and lower widths of the upper structure 20 are reduced. And it is to be able to expand the scale of the sluice (10).

That is, the winch chamber 22 is configured to be adjacent to the hydrologic chamber 23 inside the upper structure 20, and as shown in FIGS. 5 and 6, the hydrologic chamber 23 and the winch chamber 22 are disposed on the upper structure 20.

Such a shape and installation method of the index member 29 are the present invention. Since the matter can be selected by a person of ordinary skill in the art it does not limit the scope of the claims.

In addition, a support protrusion 24 protruding toward the sluice 10 is formed at one side or both walls of the sluice chamber 23 to effectively resist external forces and moments formed by water flow or water pressure when the sluice 10 is opened or closed. It is configured to, the principle of operation is shown in FIG.

That is, as shown in FIG. 7, the moment around the entrance 25 may be acted upon by the water flow passing through the waterway or the hydrostatic pressure difference between the upstream and downstream at the beginning or the end of the water gate 10. By forming the support protrusions 24 in the thread 23, effective coping is possible.

As in the elliptic enlargement of FIG. 6, a support roller 26 is installed at the tip of the support protrusion 24 to ensure smooth operation of the water gate 10 that is being opened and closed.

FIG. 8 illustrates a cantilever-type structure in a wall between the hydrologic chamber 23 and the hoisting chamber 22 in the present invention to which the hydrological chamber 23 side hoisting chamber 22 and the pulley 32 are applied. And by installing a pulley 32 to enable a more solid installation of the pulley 32, and connects both ends of the wire rope 33 to the upper gate of the hydrology chamber 23 and the winch 31, respectively, and wire rope ( By connecting the top of the water gate 10 to the movable pulley 34 coupled to 33) to reduce the required output of the winch 31 for driving the water gate (10).

Meanwhile, FIG. 9 illustrates a state in which a water channel is closed and a work space is secured for inspection and repair of the water gate 10 in a conventional venturi-type waterway. As illustrated, a crane is generally used at a starting point and an end point of the waterway. By combining the stoplog (41), which is a temporary floodgate (10), etc., water flow is blocked.

However, such a conventional water gate 10 check method requires not only additional equipment such as a crane and a stop log 41, but also requires serious closure of the waterway since the waterway must be completely closed during operation.

In the present invention, as shown in Figures 10 to 14, the above-mentioned problems of the conventional waterway was solved at once by installing a blocking door 60 that can close the hydrologic chamber 23 when the hydrological chamber 10 is stored.

First, FIG. 10 illustrates a waterway structure for installing the blocking door 60 according to the present invention. As shown in the drawing, the lower portion of the water gate room 23 is partially expanded to provide an installation space for the blocking door 60 and related accessories. Secure.

12 and 14, the bottom surface of the blocking door 60 is attached to the pressing index portion 62 surrounding the entrance portion 25 as a means for securing watertightness when closing the blocking door 60, this pressing Since the exponent part 62 is made of an elastic body such as rubber having a large friction coefficient, it may cause a failure in the smooth operation of the blocking door 60 when contacting the bottom surface of the support frame 70 or the sluice chamber 23.

Therefore, the transfer roller 61 is installed in front of the blocking door 60 so that the pressing index 62 is spaced apart from the floor when the blocking door 60 is moved, and crossing the entrance 25 of the blocking door 60. When this is completed, the feed roller 61 descends to the curved portion 71 recessed downward, and the pressing index portion 62 is in contact with the surface of the support frame 70.

Subsequently, by operating the winch 31, the water gate 10 is lowered, and when the lower end of the water gate 10 contacts the blocking door 60, the lifting door of the winch 31 is released to block the door by the weight of the water gate 10. By making the 60 and the support frame 70 adhere to each other, a high watertight state by the crimp index portion 62 can be achieved.

Meanwhile, FIG. 15 is an embodiment in which the upper structure 20 is configured as an exposed type without forming a compartment therein, thereby effectively coping with a negative pressure without filling the compartment with soil or the like. .

In the embodiment of FIG. 15, the drain 27 is formed at the inner bottom of the upper structure 20 so that water introduced into the upper structure 20 may be discharged when the water level is lowered.
