Description

Water gate apparatus using buoyancy and load

The present invention relates to a sluice gate device using buoyancy and a load, and more particularly, to provide a sluice gate device that is installed in a river, dam, or canal and uses buoyancy and the load of an opening and closing door according to the rise and fall of the water level to provide good sealing and maintenance And it relates to a water gate device using buoyancy and load, which is easy to maintain and maintain.

In general, a sluice gate is installed at a drain at the downstream end of a dam, estuary, or drainage ditch, and in the event of a flood, when the external water level rises further and the external water flows back into the district, the sluice gate is closed to prevent the inflow of external water and when the internal water level rises It is used for waterproofing by opening a sluice gate. For example, it is installed on an embankment built on the coast where the difference between the tide and ebb and flow is severe, such as rising sea level, and is mainly used to drain the water inside the reclaimed land to the sea at low tide.

In addition, when weirs are built across rivers, waterways, and canals, there is a difference in water level between the upper and lower reaches of the weirs, so a device to adjust the water level is required to allow ships to pass through. This is a sluice gate and can be classified into two types.

One is to install a sluice gate in one place of the waterway connecting the two water areas, and to install it at the entrance of the dock for wharf. This sluice gate opens the lockate at high tide to allow ships to enter and exit the dock, and closes the lockgate at low tide to unload the ship. It is used to unload cargo, and is installed in many ports in northwestern Europe, including London and Hamburg, including Incheon in Korea.

The other is a type with two lock gates and a lock chamber for accommodating ships between them, which can be seen in sluice canals. Since this mechanism needs to adjust the water level in the chamber every time the ship passes, a water supply and drainage device is required in the canal.

A lockate is commonly used as a mitergate with two doors open on both sides and no limit on the height of the ship passing through. Since the height of the gate increases, various proposals have been made in the past. For example, it has been studied to increase the height of the lock gate without increasing the height of the lock gate by installing a lift tower to raise the lock gate, which has a high construction cost and a limitation in the height of the passing ship.

Since the 1970s, Korea has been constructing large-scale drainage sluice gates, including Asan Lake, Sapgyo Lake, and Yeongsan Lake, in large-scale agricultural comprehensive development projects. It consists of 8 single gates, and each gate weighs 480 tons, which is much larger than the 320 tons of Japan's mid-sea reclamation or hexagonal water gates, which are known to be the largest in the Orient.

The maximum flood control capacity of this drainage sluice is 10,837㎥ per second, and in case of flood, 5,600 tons of flood per second is drained into the sea to prevent flooding and control the water level of the freshwater lake.

In addition, Yeongsanho has a tongseonmun (通船門) installed next to this drainage gate for the first time in Korea to allow ships to enter and exit the lake, allowing 30-ton ships to freely enter and exit regardless of the difference in water level.

However, in the conventional drainage gate, there is always a risk that the drainage gate does not go up at all or stops midway, and when it does not descend while it is raised, as well as when the drainage gate automatically descends and closes, causing serious disruptions in water drainage or accidents. I had. In addition, since the power transmission parts are connected and installed underwater or exposed to the outside, they are frequently damaged, so frequent inspections are required. There was a problem that maintenance was very difficult and impractical.

In the above, the drainage sluice gate has a large overall size and a very heavy weight, so it is very important to operate and seal well, to be convenient in repair and maintenance, and to reduce maintenance costs.

The body frame 110 includes an inlet 111 disposed so that water is introduced to the front; a discharge port 112 arranged to discharge water at the rear; A fixed flange 113 protruding along the square rim around the outlet 112 and fixedly installed with the culvert 10 and the anchor bolt B of the passage; a communication port 115 installed at a predetermined inclination angle on a passage communicating the inlet 111 and the outlet 112; It may be configured to include a hinge connecting portion 117 installed at equal intervals at the upper end of the communication hole 115 to connect and couple the opening and closing door 120 to the hinge shaft 117a.

Here, the fixing flange 113 may be formed on both the inlet and outlet sides installed in the culvert, and the shape is not necessarily limited.

In addition, the body frame 110 is a part that serves as a gate to prevent the back flow of external water, and is installed inclined toward the internal water side so that it can be quickly closed using water pressure when the internal water level rises. In addition, it is possible to use carbon steel and stainless steel for mechanical structures with high rigidity and durability that are not unreasonable for hydraulic support, bending deformation, damage by floating debris, and corrosion of contaminated water.

Here, the concave-convex reinforcement groove portion 125c enables the role of a reinforcing rib in response to the water pressure through the concave-convex groove, and serves to disperse in response to the hydrostatic pressure of sewage or waves colliding with the opening and closing door 120. can In addition, it is possible to provide a structure capable of maintaining self-reinforcing force that protects the opening and closing door from being distorted to some extent when a floating object and a large tree branch are pushed and collided with each other. This is a simplification of the structure that fundamentally prevents flood damage, and it is operated unmanned and unpowered to reduce power costs, reduce operating costs due to increased operating efficiency, and prevent failure of floodgates due to automatic operation in advance.

In addition, a through hole 125d is further formed on one side of the vertical end 125a, and the transfer line 131 of the pump 130 is connected to the through hole 125d and extends to a certain section of the water storage space. It can be formed and configured to supply external water.

5 is an exemplary view showing another embodiment of FIG. 4, wherein the buoyancy member 125 is sealed on all slopes and has a water storage space therein, and each unit body 125-1 (125) is formed in a certain longitudinal direction. -2) (125-3).

In addition, each of the unit bodies 125-1, 125-2, and 125-3 is welded and fixed to the opening and closing plate 121, and a bolt B1 and a nut fixed to the opening and closing plate 121 are between the unit bodies. It can be configured by combining the reinforcing bushing 126 that is fixedly fastened to (B2).

Preferably, each of the unit bodies 125-1, 125-2, and 125-3 is rounded (R) as its height and width gradually decrease from the middle body to both sides of the body. This is to have the ability to respond to hydrostatic pressure.

At this time, the reinforcing bushing 126 not only reinforces the self-reinforcing force of the buoyancy material, but also reinforces durability in response to the hydrostatic pressure pushed by the shape of each unit body and the shape of the valley between the reinforcing bushing, The water gate is opened from the bottom to the top by the self-load of the opening and closing door, and it can also serve as a guide passage that allows floating objects and large branches to be discharged naturally, quickly and smoothly.

Here, each unit body of the buoyancy member 125 may also be connected to each other through a transfer line (not shown) of a pump to supplement or discharge water therein.

On the other hand, a latch protruding from about the center of one side of the opening and closing door 120 to temporarily fix the raised buoyancy material 125 by being caught in the rotation ring 140 formed in the culvert or body frame 110 ( 127) can be configured to further form. At this time, one or more latches can be installed, and the shape is not necessarily limited as long as the groove structure is sufficient.

The pump 130 is connected to the inner side of the buoyancy member 125 and the transfer line 131 at the top of one side of the body frame 110, and pumps water into the inner space of the buoyancy member 125 to introduce and discharge water. As installed to do so, the inflow and outflow of water can be opened and closed by a separate check valve (not shown). Here, the pump can operate the pump to turn on/off the check valve by a control device (not shown) to inflow or discharge water, which can be possible by the control of the control device, and the configuration of the control device is general A control system connected to the check valve is used, and a detailed description thereof will be omitted.

Depending on the water level temporarily introduced and discharged from the pump 130 to the buoyancy material, the buoyancy in the state in which water is discharged from the opening and closing door and the gravity due to the load in the state in which water is introduced into the communication port of the body frame 110 ( 115) can be configured to open and close.

On the other hand, a rotating ring part 140 that rotates the hinge shaft 141 in the form of a ring is formed on the upper side of one side of the culvert or body frame 110, and the latch 127 of the opening and closing door 120 is raised upward , It can be configured to temporarily fix the buoyancy material 125 raised by being caught on the rotating ring part 140. At this time, the rotating ring portion may be installed so as to be rotatable by elastically rotatable or power control with a spring structure inside in the form of rotating the hinge axis.

8 is an exemplary view showing a state before and after operation showing that a buoyancy member is installed on the bottom surface as another embodiment of the sluice gate device using a buoyancy load according to the present invention. For the same structure below, the above structure description is followed.

Referring to FIG. 8, the opening and closing door 210 rotating on the hinge axis in the communication port 115 of the body frame 110 is rotatably installed inside the body frame 110 to move the communication port 115 horizontally. An opening and closing plate 211 for opening and closing; a pair of left and right blocking plates 213 installed on both side surfaces of the opening and closing plates 211 to block the inner wall of the communication hole of the body frame 110; Arranged in a box shape on the front side of the opening and closing plate 211 to configure a buoyancy material 215 in which sewage is temporarily stored, and the buoyancy material 215 is installed at the lower end of the opening and closing plate 211, and the pump In (130), the transfer line 131 may be vertically disposed and installed in association with the buoyancy member 215. At this time, the transfer line 131 of the pump 130 is installed vertically and can be connected to the inside of the buoyancy member 215 from the lower end.

In addition, a latch protruding from about the center of one side of the opening and closing door 120 to temporarily fix the raised buoyancy material 215 by being caught by the rotation ring 140 formed on the culvert or body frame 110 ( 219) can be configured to further form. At this time, one or more latches may be installed.

By installing the buoyancy material 215 at the lower end of the opening and closing plate 211 in this opening and closing door structure, it can be used and installed in a water gate or lock gate through which ships move.

Hereinafter, the effect of the sluice gate device using buoyancy and load according to the present invention will be described. The following description follows the above structural description.

On one side of the body frame 110 connected to the sluice culvert where the inlet 111 through which external water flows in and the outlet 112 through which internal water is discharged are disposed at the rear, and the outlet 112 of the body frame 110 The hinge portion is rotatably coupled to include an opening and closing door 120 that opens and closes the outlet of the body frame 110, and the opening and closing door 120 pumps water through the transfer line to the inside of the buoyancy material 125 Alternatively, it is introduced and discharged to the outside to open and close the outlet 112 of the body frame 110 with gravity according to the load in the state in which the water is introduced and the buoyancy in the state in which the water is discharged to the buoyancy material of the opening and closing door according to the water level.

On the other hand, when the buoyancy material descends due to the gravity of the state in which water is introduced into the buoyancy material 125 by pumping, the water gate is closed, so that flooding is prevented by the buoyancy of the buoyancy material by pumping as an initial response in the event of backflow, and the opening and closing door 120 As the water gate closes from top to bottom with its own gravity, floating objects and large tree branches can be induced and discharged naturally quickly and smoothly.

In addition, due to the simplified structure, it is operated unmanned and without power, reducing power costs, reducing operating costs due to improved operation efficiency, preventing flood gate failure due to automatic operation, and preventing flooding by prompt initial response in the event of a natural disaster, as well as pumping operation The buoyancy of the buoyant material and the gravity operation according to the load enable smooth and accurate opening and closing operations.

Existing lifting-type floodgates are limited in scale due to limitations in lifting the door. Drainage performance can be improved through smooth operation, since transported materials are caught in culverts, which reduces drainage efficiency and sluice gates do not close completely, resulting in backflow problems.

In addition, by applying a buoyant material to enable automatic opening and closing using buoyancy, it is operated in real time when the external water level rises to ensure efficient drainage, and it can be opened and closed in real time even when the external water level goes down, so the drainage is excellent. Depending on the change in flow rate, approximately 3% to 10% more is secured, enabling efficient drainage.

In addition, the opening and closing of the water gate to prevent backflow due to the rise in the external water level is made with a structure and function that facilitates quick and accurate response to various environments. Do.

In addition, when the external water level starts to rise, the operator closes the water gate by operating the power source and the lifting device, and when the external water level begins to descend, the water gate is opened for smooth drainage of domestic water. However, it is difficult to predict the rise and fall of the external water level depending on the characteristics of the water level, and it is difficult to operate the opening and closing. By opening and closing the floodgates using buoyancy by pumping without a separate power source or device without predicting the regional characteristics and water level of rainfall, it is possible to operate conveniently without time and space restrictions.

In addition, the sluice gate device of the present invention opens and closes the sluice gate using buoyancy without a separate power source and opening and closing device, so it does not require electricity usage fees, operator wages, and maintenance costs of the lifting device of the existing lifting type sluice gate. ㆍThe facility has been developed and economical improvement is possible by applying materials with excellent durability.

In addition, the sluice device is installed in a place to prevent the backflow of external water and the exclusion of domestic water, and it is also installed on salty seashores, drainage gates in industrial complexes with a lot of chemical components in factory wastewater, steep slopes where the river bed is gravel, and drainage gates in mountain streams. As such, sluice gates installed in these environments are vulnerable to corrosion problems caused by salt and chemical components, durability problems against impact forces caused by floating debris and rolling stones at the bottom of the river, etc., but stainless steel, which is superior in durability to conventional steel, was used, The vulnerability to chemistry and corrosion has been solved. Stainless steel (STS 304, STS 316, etc.), which is the material used this time, is a product with improved durability by preventing corrosion in the metal structure due to the characteristics of stainless steel. In addition, the backflow blocking packing to secure watertightness is made of N.B.R (Ncrylo Vitrile Butadine Rubber), a typical oil-resistant synthetic rubber with higher durability and chemical resistance than general rubber. This excellent material was used that can be easily processed into any shape.

Although the present invention has been shown and described with preferred embodiments as described above, it is not limited to the above embodiments, and to those skilled in the art within the scope of not departing from the spirit of the present invention Of course, various modifications and variations are possible within the technical spirit of the present invention and the equivalent scope of the claims to be described below.
