に注意して調整を怠らないようにしなければならない。First, in normal times, the purpose of operation is to store fresh water in the river channel, and at the lowest spring tide when only fresh water is flowing into the river 3, the small doors 10 and 10' are closed, and the small doors 9 and 9' are closed. Open it and make the water level of water surface 4, 4' the same as the water level of sea 7,
If the connection between the bridge 21 and the rods 22, 22' is adjusted to position the top of the door 1 slightly higher than the water line of the floats 15, 15', the seawater will be dammed up by the weir 1 and flowed into the river 3. Similarly, the river water is also dammed up by Door 1 and is stored at the mouth of the river without flowing out to Sea 7. When the tide begins to rise, the sea 7
As the water level rises, the top of door 1 also rises, but in this case, the rising speed of the water level of river 3 due to storage of river water is slower than the rising speed of the water level of sea 7, so the water level of river 3 becomes lower than the water level of sea 7, door 1 becomes heavier by the lower water level of river 3, and the load is applied to floats 15, 15', causing floats 15, 15' to sink by that amount, so the depth of this sinking is At first, the top of door 1 was made slightly higher than the water line of floats 15 and 15'.
Since seawater will enter the river 3, care must be taken to ensure that the top of the door 1 is not lower than the water line of the floats 15, 15'.

したものである。When the tide reaches its peak, the top of door 1 rises to the same height as the sea level at peak tide, but as the tide moves from peak tide to ebb, the rising water level 4,4' Since the water level will also drop, to avoid this, by closing the small doors 9 and 9' and closing all the small doors, the water level 4 and 4 at the highest tide will be lowered.
The top of the door 1 is also positioned at the same height as the water level of the water surfaces 4 and 4'. This completes the first stage of operation. Next, as the days passed, the water level of river 3 rose,
When the predetermined limit water level is reached, the small door 10
, 10' are opened to make the water level of the water surface 4, 4' the same as the water level of the river 3, and the height of the top of the door 1 is lowered by an appropriate depth to allow the river water to overflow, and the water level of the river is lowered. It must be ensured that the water level does not exceed the limit water level. Furthermore, Figures 2 to 4 illustrate a state in which the water level of the river 3 has reached the water limit level, the sea water level is lower than the river water level, and the discharge of river water is about to begin.

述べる。Furthermore, in the event that there is a risk of flooding, immediately open the small doors 10, 10' and open the small doors 9, 9' to bring the water level of the water surface 4, 4' to the same level as the water level of the sea 7. However, the top of the door 1 must be located at the same height as the water line of the floats 15, 15'. In this case, the top of door 1 will always be at the same height as the water level of sea 7, so door 1 will always close the area from the river bed 5 to the water level of sea 7, and
In addition to preventing seawater from flowing backwards in the direction of River 3,
Floodwaters flowing down can overflow the weir and be dissipated into the sea by simply encountering air resistance without colliding with the backflow of seawater, so the loss of potential energy and kinetic energy is extremely small, promoting the flow of floodwaters into the sea. Therefore, from a flood control perspective, this is the best operation method, so we must continue in this state until the danger of flooding has passed.Next, the above operation method is a multi-purpose, fine-grained operation method, A labor-saving operation method that takes advantage of the greatest advantage of this embodiment will be described.

い。This operation method works when river water is always flowing at a high flow rate.
Movable weirs installed at the mouths of rivers that flow into the sea, where there is a large tidal difference, have the purpose of preventing seawater from entering the river, preventing the salinization of river water, and promoting the outflow of river water to the sea. This is an extremely labor-saving device that aims to achieve only two purposes: flood control and flood control, and the operation is completed with just one operation, and all that is left to do is maintenance and inspection, and the device continues to work automatically. be. That is, close the small doors 10, 10',
Open the small doors 9, 9' to make the water level of the water surface 4, 4' the same as the water level of the sea 7, adjust the connection between the bridge 21 and the rods 22, 22', and attach the top of the door 1 to the float 15, If the weir is located at the height of the 15' water line, then the manual operation of the weir is over, and from now on, if the sea level rises or falls, the water level at water surface 4,4' will rise or fall in the same way as the sea water level. Float 15 floating on
, 15' are raised and lowered in the same way, and turret 2 connected to this
0, 20', bridge 21, bars 22, 22', and the top of door 1 rise and fall in exactly the same direction and height as floats 15, 15', so the water level of sea 7 and the water line of floats 15, 15' and The top of the door 1 will always be on the same horizontal line. Therefore, since the door 1 always closes the area from the riverbed 5 to the water level of the sea 7, it has the effect of completely preventing seawater from entering the river 3 and preventing saltification of the river water in terms of water utilization. Instead, it prevents the backflow of seawater from the sea 7 to the river 3, and the river's original flowing water does not collide with the seawater backflow, but only receives air resistance, overflows the weir and dissipates into the sea. It also has a remarkable effect on flood control by promoting the flow of water.

る。Conventionally, in this type of movable weir, the bridge 21 was installed at a low location, so when the floats 15, 15' were lowered, the frames 2, 2' separating the river 3 and the water surface 4, 4' The bridge 21 has no choice but to cut into the river 3, the guide groove and the water surface. 4,
There were various constraints such as the need for special measures to prevent the movement of water between float 15' and
, 15' are lowered to their lowest positions, the bridge 21 remains in the air, so it is no longer subject to the above restrictions.
Regardless of the shape, it can be made into a sturdy and inexpensive device. Furthermore, in the conventional type, the rollers provided on the floats 15 and 15' are all single-stage, and their only function is to reduce longitudinal and lateral vibrations in the direction of the flow of the river 3, as well as frictional resistance during lifting. This function was maintained by fixing the connection between the left and right floats 15, 15' and the bridge 21 and balancing the buoyancy forces received by both floats 15, 15'. The rollers in the two upper and lower stages move up and down between the vertical doorstops of the guide grooves provided on both sides, ensuring the ability to move up and down in the vertical direction. , the floats 15, 15' only need to be able to receive buoyancy sufficient to raise and lower the series of devices, and there is an effect that the floats 15, 15' can be made smaller.

的を達することができる。In short, when closing a weir, the weir is closed and opened from the bottom to the top by keeping the bottom or the bottom of the door or a series of doors in close contact with the bottom of the water surface and raising and lowering the top. As long as the door can be opened from the top to the bottom, any door can be used to achieve the goal.

The purpose can be achieved even if it is installed anywhere on the water surface, such as between moats and moats, or between moats. Furthermore, if they are installed in several locations and linked together to collectively adjust the movement of water, the effect will be even greater.

きる。The first embodiment relates to a small river in which a large number of doors are installed, while the second embodiment relates to a large river in which a large number of doors must be arranged horizontally. In the case of a large river, the frames 2, 2, which have the same width as the weir pillar 29, the same direction as the weir pillar 29, the same size and the same shape, are used as the weir pillar 2.
Floats 15 of the same size and shape are attached to the weir pillars 29 on the upstream and downstream sides of the frame bodies 2, 2.
For example, if a bridge 21 is installed between the downstream turret 20 and the downstream turret 20' adjacent to the left and the door 1 is placed under it, then Upstream turret 2
By arranging the doors 1 alternately, such as by placing a bridge 21 between the bridge 21 and the bridge 21 and positioning the doors 1 under the bridge 21, a weir with the same operating method and effects as the first embodiment can be provided. can do.

This system prevents the backflow of river water and the upstream flow of river water driven by seawater, and promotes the outflow of river water to the sea by allowing the original river water to flow over seawater and backflow water. If the purpose is narrowed down to two purposes: flood control and water control, use the existing bridge piers, connect the frame 2 to either the downstream or upstream side, and float the float there. If this is the case, the foundation work cost will be lower and only one frame and one float will be required for each pier, so the weir can be installed at a cheaper price.

を提供せんとするものである。Two examples have been described in detail above, one for a small river and one for a large river.
In a movable weir, the top of the weir is raised and lowered so that when the weir is closed, it closes from the bottom to the top, and when the weir is opened, it opens from the top to the bottom. To provide a movable weir that can raise and lower the top of a door in conjunction with the raising and lowering of a floating body.

この場合，浮体の昇降というのは，陸地に対する関係に
於て昇降するという意味である。In this case, raising and lowering the floating body means raising and lowering it in relation to the land.

いまこの発明の特色についての理解を容昜にするために
，水面は昇降することなく静止していて，逆に陸地の方
が昇降すると仮定した場合には。Now, in order to clearly understand the features of this invention, let us assume that the water surface remains stationary without rising or falling, and conversely, the land surface rises and falls.

陸地のうち堤防の部分は高いので常に海の水位よりも上
にあるが，河道の部分は低くなつているので，陸地が下
つたときにはそこから海水が河川に侵入してくるので，
之を防ぐため河道に堰を設けて堰の頂部が常に海の水位
と同じくなるように堰の頂部を昇降させ続けて行けば，
陸地には海水は１滴も侵入しない訳であり，一方陸地が
水面より浮上しているときには，扉の頂部を常に海の水
位と同じ高さになるように降昇させて行けば，陸地が海
面より下つて排水できない時に陸地にたまつた水を 排水する時間的余祐は十分にあるように思われる。The part of the land that is the embankment is so high that it is always above the water level of the sea, but the part of the river channel is low, so when the land goes down, seawater intrudes into the river from there.
To prevent this, if we build a weir on the river channel and keep raising and lowering the top of the weir so that the top of the weir is always at the same level as the sea water level,
Not a single drop of seawater enters the land, but on the other hand, when the land is above the water surface, if you lower the top of the door so that it is always at the same height as the sea water level, the land will rise. There seems to be enough time to drain the water that has accumulated on land when it cannot be drained below sea level.

考えを現実に戻した場合，フロート１５，１５′の吃水
線に扉１の頂部の高さを一致させておくということは前
述の仮定の場合に於て堰の頂部を海の水位に常に一致す
るように昇降させ続けることに相当する。仮定の場合に

，この発明の堰の場合には，海との関係に於て不動の関
係をたもつている間に，陸地に対する関係に於ては自動
的に堰の頂部が昇降することとなり極めて省力的である
。Returning to reality, keeping the height of the top of door 1 consistent with the water line of floats 15 and 15' means that in the above assumption, the top of the weir is always aligned with the sea level. This corresponds to continuously raising and lowering the vehicle. In the hypothetical case, the top of the weir would have to be raised and lowered manually, but in the case of the weir of this invention, while maintaining an immovable relationship with the sea, In relation to the land, the top of the weir automatically moves up and down, which is extremely labor-saving.

更に貯水目的を加味してきめこまかく水の移動を調整し
ようとするときには，橋２１に対する棒２２，２２′の

宜に調整することかできて極めて効果的である。Furthermore, when attempting to finely adjust the movement of water in consideration of the purpose of water storage, the flow rate, etc. of the water flow can be adjusted as appropriate by adjusting the height of the rods 22, 22' relative to the bridge 21. It is extremely effective.
