Abstract

PURPOSE:To perform automatic fall of a bagform weir, by a method wherein a weir stands upright, a water level on the upper stream side is raised, and when a water level in a float chamber is raised to a given level, arms are rotated to open an exhaust valve. CONSTITUTION:By feeding fluid, such as air, a weir 1 stands upright, a water level on the upper stream side is raised to a storage water level L2, a water level in a float chamber 9 becomes equal to the storage water level L2, and an exhaust valve 7 is forced into a closed state. When a water level on the upper stream side is raised, a water level in a float chamber 9theta is raised, a hopper 21 is lowered, and arms 8a, 8b, and 8c are rotated to open the exhaust valve 7. Fluid in the bagform weir 1 is drained from an opening 6a through a feed air pipe 5, an exhaust pipe 6, and the exhaust valve 7, the weir 1 is started to fall, and a water level on the upper stream side is lowered. This, when overflow water is increased to a fall water level, enables reliable fall of the weir.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides six rubber bag weirs for the purpose of taking water from rivers, lakes, etc. for water supply, industrial water, agricultural water, public water, etc. during floods. , relates to an automatic lodging device for automatically lodging.

(Prior art) Conventionally, this frame was equipped with +? J is a method in which river water is injected into a container as the flood level rises, and the exhaust valve is opened by the weight of the container, and the exhaust valve is opened by the buoyancy generated in the float as the flood level rises. There was one that opened in one go.

(The point that the invention is trying to solve) However, in both types, the rubber bag-shaped weir is self-contained! l! After it collapses, there is no mechanism to automatically close the exhaust valve, so flooding may occur in the control room built inside the embankment, and the floodwaters will cross the embankment from within the slick river and enter the embankment. It was necessary to install 114 water conduit pipes.

However, if the water conduit that guides the floodwaters becomes clogged due to sediment, etc., there are problems such as the Gomutaibō weir lying in its place, and a large amount of civil engineering costs are required to install this water conduit. It also requires management of Cape Shugenga. Furthermore, in both types, river water that had not been injected into the container was removed every time the rubber bag-like weir automatically collapsed, and a reset operation such as setting a 70-ton stopper was required.

It is a lick that solves the above-mentioned intercondylar point in 1111, and the intercondyle occurs due to being blocked by earth and sand, etc.・4
By turning the water W into the shade, the operation hand r111 & fff (
After one night, the reset operation is only required to raise the bag-like weir, and moreover, the construction work can be reduced to 7'1. .

(11-(Yellow f;/Means for Solving)) In order to achieve the above object of the present invention, in a bag-like weir installed by cutting a river into pieces, air blowing is installed on the bag-like weir, etc. An exhaust pipe opened to the atmosphere, both having an exhaust valve, is connected to the river between the float chamber and the real chamber, which are separated by a bulkhead. The float chamber communicates with the upstream side of the bag-shaped weir, and the hopper chamber communicates with the downstream side of the bag-shaped weir. A hopper ff having a drainage hole in a corner located in the hopper chamber is connected to the arm of No. 1;
The second arm has a Z float located inside the float chamber. A weight is connected to the third arm, and the bulkhead mJ is a bag-shaped weir σ) (I).

The tuna water supply pipe is installed so that water can be injected into the river water inside the float chamber. In case the lower boiling water level rises, the river water in the float room is injected into the hopper No. 11 through the water supply pipe, and as the hopper descends, the exhaust valve is closed. It is characterized by opening, discharging the sealed weir, and lowering the bag-shaped weir by +11.

Q by making 141W of Kizu T and 1 valve 7
; :rX: By releasing the sealed fluid in the weir 1 through the exhaust pipe 6, the weir 1 can be collapsed.

The intrusion resistant body is equipped with 7 exhaust valves that open and close automatically as shown below.

On the slope of the bank of the river, as shown in Figure 2, the water surface of the river upstream of the weir is placed on the river surface of compartment 8 where compartment 8 is installed. An inlet hole 12 is provided. The compartment is divided by eight partition walls 10 into a float chamber 9 on the downstream fill and a hopper chamber 11 on the d1 side.

The base of the water supply pipe 13 is in contact with the partition wall + (l F + dimension) so as to inject water into the hopper 21 arranged in the hopper room 11.The center of the base of the water supply pipe 13 is at the subsurface water level L1 of the weir. The height of the bulkhead 1 is higher than the water level L1.

In order to drain the indoor water from the hopper chamber 11 to the downstream of the weir, connect the -@ of the drain pipe 15 to the 7-t which opens at a level slightly higher than the river bed 11, and connect the -@ of the drain pipe 15 with the other end of the dam. It is installed so that it opens onto the downstream bank slope.

Inside, on the stand of the partition wall 10, a q-sized exhaust valve 7 is arranged in the middle of the exhaust '6, and the main shaft 16 connected to the valve M of the exhaust valve 7 has three arms 18a. .

1δb and 18c are fixed. arranged in a vertical line t
Arm 1) Ia, Ihh connection material 19.211
k via the hopper 21. A float η is attached to each. Try connecting the weight 17 to the arm 18c of A3.

Water is injected into the top of hopper 2 from water supply pipe 13, and the water is poured into river B.
A large drainage hole 14 is provided to drain water. ◇ Drainage (pipe 6f and open end 6a are opened above the slope of the river bank and at a light level high position. Therefore, there is no intrusion of water from the open end 6a.

Further, as the connecting member 19.21J, a material such as a wire that can be bent freely is used.

13! The operation of the present invention will be explained below. When the weir 1 is erected to the state shown in Fig. 3 by sending a fluid such as air, the upstream water level rises to the reservoir water level L2.
/-0 In this state, the upstream water intrudes into the float chamber 9σ at iQ manhole 12, so the water level in the float chamber 9! -j is equal to the storage level L2. Then, the float B stops sagging, and no tension is applied to the lumber during storage. ...Is there tension in 1 binding material 2 + 1? Even if this happens, the weight 17 and the hollow 21 have a balance of σ and moment of 7, so the wandering valve 7 remains closed and the
Haru.

When the water level reaches the upper reaches, the weaving begins. When the water level of the overflow water increases and reaches the overflow level L1 as shown in FIG. The hopper 21 is gradually filled with river water due to the difference between the amount of water flowing in from the water supply pipe and the amount of water discharged from the discharge hole 14. When it reaches the bottom, it descends to the hopper 2, as shown in Fig. 5. This descent causes the arms 8a, 8h, and 8c to rotate counterclockwise, opening the exhaust valve 7. The fluid drain φ trachea 5, the exhaust/ρ 6, and the drain valve 7 are passed through the opening 6 of the mushroom 6.
It will be discharged. As a result, the bag-shaped weir 11- starts to bow down, and the water level in the soil does not decrease. , assumes the lowered position, during which the exhaust valve 7
Continue to diverge (Figure 46). Water injection into the water supply pipe 13 has stopped due to the drop in the upper critical water level, so the hopper 21
The river water in the hopper chamber 11 is only discharged, and during the 0th period when the drainage is finally completed, the river water in the hopper chamber 11 is discharged downstream through the drainage g15. Furthermore, when the water is opened, the water fh''t in the float chamber 9 also falls as the water level falls, and when it falls to the water level, as shown in FIG. 7, the connection member connected to the float η is Therefore, when the water level rises further, the rotational keyment due to the weight of the float n acts on the main shaft 16, gradually closing the 7 exhaust valves◇And at this 1 tM, the fluid in the eel-shaped weir 1 flows through the exhaust pipe 6. 1. Analyze and drain completely.

After that, as the water level in the float chamber 9 decreases, the float 2
2mo lowers, float n and weight 17 years old 17N clockwise l! l! 1. No movement, water level rises to 1. Reached s-
Since the weight 17 rotates from the center position 1k to the float chamber 9 side, close the exhaust valve (turn 8).
.

When fluid is sealed in the bag-like weir 1 in the state of Asahi sH through the air supply pipe 5 by means of an air blower system, the bag-like weir rises and water can be retained in the upstream part (Fig. 9).

When the water remains, the water level in the first float chamber 9 rises, and the float thorn floats to the surface.

If the height of the weir 1 is set to the height shown in Fig. 43, the operation described above will be accomplished.

(What's the point?) Since the present invention consists of breaking the precepts of old age, most of the construction of the structure can be done by laying a bag-shaped weir and installing it near the Nenkari riverbank, so that 11 It is possible to install water pipes without having to worry about it, and furthermore, once the bag-like weir is erected, if the water level reaches 1-1, the cap-like weir will be reliably turned into 1-down.
