Description

[Technical Field]

[0001] A device that guides the water flow of a river to make effective use of the river. [Background technology]

[0002] The devices that guide the flow of the river are not usually visible, but sometimes you can see large construction machines digging the riverbed. Strangely enough, there is no flowing water in the center of the river. This technology changes this and guides the flow of the river, directing the water flow to the center of the river. I couldn't find any documents about river flow guide devices, but I heard that in some regions during the Sengoku period, triangular levees were used to protect rice fields and farmland, but I don't know the details. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-221376 Summary of the Invention [Problem to be solved by the invention]

[0004] When observing the flow of water in the middle or downstream of a first or second class river, you will find that the water does not flow through the center of the river, but rather flows in a winding pattern from side to side. This device guides the flow of river water to the center of the river, solidifying and deepening the river bottom and adjusting the width of the flowing water.

[0005] Using a river flow guide device, it is possible to guide the flow of water to the center of the river, protecting breakwaters and structures, and to reduce the force of the water flow, concentrating and spreading the water flow in the center of the river, thereby making it possible to use the river more effectively.

[0006] If you look at maps or aerial photographs of Japan's rivers, you can see that the water flowing through them undulates greatly, and that there is a deep riverbed around the occasional large rock, and that there are solid bedrock and large rocks at the head of the current. Looking a little more closely, you can see that at the end of the rough rapids there are bedrock and large rocks, and around them is a deep riverbed, where there are a collection of large and small rocks on the riverbed but little sand or gravel, and in front of the bedrock and large rocks there is a pool with a deep riverbed, and the bottom of the pool is filled with large and small rocks, and a little downstream there is gravel and sand, which makes the riverbed shallower and widens the water flow, and a little further downstream there is a collection of gravel and sand, and you can see that the collection of sand forms the riverbed.

[0007] People who like Ayu fishing say that you should bring stones with you when fishing for Ayu.The logic behind this is that in places where there are a lot of large and small stones gathered together, fresh moss grows due to changes in the water flow, and you can catch a lot of Ayu that come to eat this moss. Even at fishing spots like this, if you go there for many years, the large and small stones change, and the surrounding riverbed becomes deeper as the water current changes, so the large and small stones are shaped like the bottom of a pot and the area around them is deep.When you look at the riverbed through a box-shaped glass, you can see that there is no gravel or sand, but that the riverbed is solidified with large and small stones, and the riverbed on both sides is deep.When you look at the larger stones, you can see that their bottoms are shaped like the bottom of a pot.When I tried to draw a diagram by imitating this, I came up with the shape shown in Figure 2. If you look more closely, you will see that gravel and sand have accumulated downstream of the larger stones, but if you look in a different area, you will see that there is no gravel or sand accumulated, but there are smaller stones downstream of the larger stones, and the riverbed on both sides is deep. If you copy these two and draw them on a blueprint, you will get a shape like the one shown in Figure 6, and if you connect or link these, it may be possible to guide the water flow in the river.

[0008] To carry out the above, if a device like the one shown in Figure 6 is devised and installed in a river, it may be possible to narrow or widen the width of the river flow.In this case, rather than using a single river flow guide device, if several river flow guide devices are connected together and installed downstream, it may be possible to guide the river flow to the center of the river.Also, if tick pots and block balls are connected alternately and installed separately, it may be possible to soften the flowing force of the river water flow and narrow or widen the width of the water flow.Furthermore, if they are installed alternately with concrete blocks on the coast, iron-loving organisms such as seaweed and shellfish will gather and grow, which may prevent tide burn and fix artificial structures.

[0009] The piles of the river flow guide device are driven firmly into the riverbed deep, and the top part has a function that can be used as a base for an observation measuring instrument, a vertical wind turbine, etc., and a tick pot is connected or joined to the end of a chain or wire extending from the pile, so that the piles stop the tick pot and block balls from being washed downstream even if the river water flow becomes large.

[0010] The chick pot is connected or linked to the end of a chain or wire extending from a stake, and the chick pot has a tip claw, a pot-shaped bottom plate, and hooks with joints at the front and back of the upper part, and is made of reinforced concrete blocks, and when the flow of river water increases, the up / down and left / right movement is transmitted to the tip claw to deepen the river bottom.

[0011] The tip claws attached to the front of the tick pot are usually stuck into the riverbed, and when the river water flow becomes strong, the movement of the tick pot may have the function of moving large and small stones on the riverbed downstream, deepening the riverbed.

[0012] The pot-shaped bottom plate is a plate attached to the bottom of the tick pot, and it is required to protect the tick pot from stones and gravel, and to have the function of sliding up and down on the stones in a small round shape to deepen the river bottom.

[0013] The jointed hooks attached to the front and rear of the upper part of the tick pot are devices for connecting or linking chains or wires, the jointed hook at the front is connected to a stake by a chain or wire, and the jointed hook at the back is connected to a block ball by a chain or wire, and these devices eliminate twisting distortion that occurs when the tick pot moves up and down and left and right and the block ball rolls.

[0014] The chains or wires connecting the stakes, tick pots and block balls must be strong and able to withstand the seasons for a long period of time. The length varies depending on the river, but the spacing must be such that the tick pots and block balls can move up and down and left and right.

[0015] The plates on both sides of the tick pot are designed to prevent the tick pot from being damaged even if large or small stones or gravel hit it during floods.

[0016] A river flow guidance device is ineffective when used alone, so by installing several tick pots and block balls downstream, the river bottom is deepened and the amount of water flowing into the river is guided to the center of the river, and by installing it in a clever way, it can also change rising water currents into gentler currents. [Means for solving the problem]

[0017] In order to guide the water flow of a river to the center, a river flow guide device can be used to gather the flow of river water to the center and create gentle rapids, using natural forces and the function of dispersing the flowing force during occasional floods.This can be achieved by effectively using a river flow guide device in the river.

[0018] The purpose of installing river flow guide devices is to guide meandering river water flow toward the center of the river by installing several river flow guide devices downstream, which will change the flow of the river water in a few years; and to change rough rapids into gentle rapids, by installing river flow guide devices in a clever way, the river water flow will change in a few years, the flow of the water will widen, and gentle rapids will be created.

[0019] The river flow guidance device is composed of a chain or wire that connects to the pile, a tick pot, and a block ball.The pile is a device that is installed at the front of the river flow guidance device and is a strong pile that will not be damaged even if the river water flow becomes large, and the front part is equipped with the function of installing observation equipment and a vertical wind turbine.

[0020] A chickpot is a device that is connected or joined to a chain or wire extending from a stake, and is shaped like a chick.When the river water flow becomes large, the chickpot moves up and down and left and right on large and small stones, deepening the river bottom.The chickpot is a device that has the function of stopping it from rolling.

[0021] The block ball is a block ball device that has a ball-like shape and is connected or joined to a chain or wire extending from the tick pot, and when the river current becomes large, it moves up and down and left and right on the stones and rolls, deepening the river bottom, causing gravel and sand that tend to accumulate behind the tick pot to flow downstream, and sinking large and small stones that did not flow down to the river bottom.

[0022] The tick pot and the block ball are connected or linked by a chain or wire, and move; the tick pot moves up and down and left and right, and the block ball rolls, dispersing and weakening the force of the river water flow and deepening the river bottom; when the tick pot and the block ball are used together, the device has the function of deepening the river bottom on both sides and guiding the widening water current. [Effects of the Invention]

[0023] 1. The water flowing in the river can be collected in the center of the river. 2. An imaginary illustration of a riverbed that protects a breakwater by selecting stones, gravel, and sand that flow into the river and dividing it into slightly larger stones in the center of the river, then gravel and sand. 3. By adjusting the distance between structures, it is possible to create blocks of stone or gravel on the riverbed between the structures, which may naturally create an island. 4. The riverbed can be used as a park. 5. A water level sensor or a vertical wind turbine can be installed on the upper part of the tip pile. 6. There is a possibility that it may protect organisms migrating upstream. 7. If they are installed on the coast, iron-loving seaweed and shellfish may gather there and prevent seaweed burn and help to fix artificial structures. [Brief explanation of the drawings]

[0025] When viewed on a map or from above the bridge piers, the water flowing in the river meanders downstream. Looking more closely, we can see that there are bedrock and large stones at the end of the rough rapids, and around them is a deep riverbed caused by the river current, deepening the riverbed.

[0026] This natural phenomenon can be used to direct the water flowing into the river as a device to protect breakwaters and bridge pier foundations by using the force of the river's flow to direct the water flow towards the center of the river. To direct the water flow towards the center of the river, the river flow directing device can be installed facing downstream. The water flow that flows into the river due to occasional flooding can be changed by the river flow directing device, and large and small stones can be selected by the change in the river water flow, and the riverbed can be deepened by the movement of the river flow directing device. The riverbed can also be deepened by the up and down and left and right movement of the tick pot, and the up and down and left and right movement of the block balls can be used to move the gravel and sand that tend to accumulate behind the tick pot downstream, and large and small stones that did not flow downstream can be settled in the river, creating a stable riverbed.

[0027] The strong piles are piles that do not allow the river flow guide device to be washed downstream, and are equipped with hooks at the top that can be used to attach a water meter or a vertical windmill, and chains or wires. The chain or wire connecting the stakes of the river flow guide device should be adjustable in length, and the distance between the stakes or wires and the tick pots and block balls will vary depending on the river, but as a guideline, it should be determined by the shape of the gravel masses.

[0028] The river flow guidance device is shaped as shown in Figures 2 and 3, and is attached or connected to a chain or wire facing downstream. The water flow changes on both sides, deepening the river bottom, and by maintaining this depth for a long period of time, it is possible to guide the river water flow.

[0029] The pot bottom plate attached to the bottom of the Chick Pot has a rounded bottom similar to that of a pot kettle, and is designed to move up and down and left and right over large and small stones.It is a pot bottom plate attached to the bottom of the Chick Pot to prevent the Chick Pot from being damaged even if large and small stones come into contact with it.

[0030] The chain or wire is designed so that when gravel and sand on the riverbed are washed downstream, the large and small stones supporting the tick pots and block balls become unstable and move to the left or right, deepening the riverbed; the length of the chain or wire determines whether this depth or width is narrowed or widened.
