In other words, through the side wall (2) (2 ') and the adobe block (B) as the bottom surface (1) on both sides, the drip wall (10) for storing the temporary water and the air through which some water flows downstream This waterway hole 12 is formed. This adobe block (B) is always open to the water flow in the flood season and used to store the temporary water even in the dry season, this is a certain amount of water is filled in the adobe block (B) by the drip wall (10) and then again It is equipped to flow.

To this end, it is provided with an airway control mechanism 15 to open and close the waterway hole 12, the through-hole of the drip wall 10, the airway control mechanism 15 is a hydrological control unit 20 to directly open and close the waterway hole (12) ) Was provided. The water gate control unit 20 is provided to determine the opening degree of the waterway hole 12 according to the opening and closing degree of the opening control plate 22 rotated by the rotating shaft 21 fixed to one side of the drip wall (10). .

In particular, the fish control mechanism 15 is to be movable up and down along the wall surface of the drip wall 10, floating in water to form the floating portion 30 to be linked up or down depending on the height of the water up and down It is equipped with. The floating part 30 may be easily formed of a light material such as a styropole, and may be provided with a metal material so that the outside thereof is not destroyed by a force of strongly pushed water.

In addition, a metal material may be provided as an external body so that the air is filled inside and sealed.

Further, the portion facing the drip wall 10 to facilitate the rising and falling can be formed in a flat surface, and also to rise and fall by a predetermined height, and floating body portion 30 so as not to be separated from the drip wall (10). It may be provided with a floating body bracket (35) to guide the movement of. The float portion bracket 35 has a "c" shape to be fixed to the drip wall 10, and the engaging projections 32 on both sides of the float portion 30 in the space between the inner space and the drip wall 10. It may be provided to be fitted so as to be raised and lowered.

Thus, the floating portion along the drip wall 10 by the high and low of the water contained in the side wall (2) (2 '), the bottom surface 1 and the drip wall 10 on both sides of the adobe block (B). 30 is raised or lowered, whereby the open control plate 22 of the hydrologic control unit 20 which is connected to the floating body portion 30 and the rope 31 is rotated around the rotating shaft 21 In the end, the waterway hole 12 is to be opened and closed. The open control plate 22 is preferably provided with a metal material or a synthetic resin material (plastic material) of weight, and may be used by pouring concrete and curing.

In particular, the airway control mechanism 15 of the present invention block (B) may be provided with a water gate control unit 20 as one open control plate 22 for one waterway hole (12).

In addition, as shown in the accompanying drawings, with respect to one of the waterway hole 12, it may be provided with a hydrological control unit 20 as the two opening control plate 22 which is rotated to open on both sides.

That is, the opening control plates 22 and 22 'of the hydrologic control unit 20 are provided in pairs on both sides, so that the water flow hole 220 is formed in the part facing the waterway hole 12. . And it is provided with the opening and closing plate 221, 221 'is a plate-shaped body coupled to be rotatable with respect to the opening control plate (22, 22') to control the amount of water flowing into the water flow hole (220). In addition, the front ends of the respective opening and closing plates 221 and 221 'are connected to the ropes 31 and 31' so that the front ends of the opening and closing plates 221 and 221 'are opened or closed to both sides. .

Accordingly, the opening and closing plates 221 and 221 'have upper and lower surfaces surrounded by a triangular plate, and a central plate of the opening and closing plates 221 and 221' connected to the ropes 31 and 31 'has a wide plate shape. In the form, the opening control plate 22, 22 'and the portion that is coupled to the hinge is opened to each other and coupled to each other, the front end of both opening and closing plate 221, 221' is in contact with each other in a closed state Is installed. When water flows down from the upstream, the water splits to both sides at the contact portion in front of the opening and closing plates 221 and 221 '.

As the float portion 30 rises, the opening and closing plates 221 and 221 'on both sides rotate about the folding and the like, and the front flows outward to both sides, so that the water flows through the opening control plates 22 and 22'. Water flows into the ball 220. As the water flowing in the water flow hole 220 is further increased, the opening and closing plates 221 and 221 ′ of both sides are pushed outwards, and the water flowing through the water flow hole 220 eventually opens and closes the opening and closing plate 221. 221 'is pushed to both sides and the opening control plates 22 and 22' are rotated about each of the pivot shafts 21 and 21 'by the force of the current.

That is, since the opening control plates 22 and 22 'are generally installed with heavy weights, the buoyancy force of the floating part 30 may not rotate the opening control plates 22 and 22', but the water flow hole ( 220 and the opening control plates 22 and 22 'are also rotated outwardly by pushing the center plates of the opening and closing plates 221 and 221' outwards by the strong force of the water flowing through the water hole 220 and the water hole 12. The waterway hole 12 is to be opened.

The opening control plate 22, 22 'may be further provided with an open side fluid 222 to the upper side. By the opening part fluid 222 is provided to facilitate the rise of the open control plate (22, 22 ').

Referring to the operation of the present invention Adobe block (B) provided as described with reference to Figure 4a to 4h as follows.

That is, the fish control mechanism 15, which is the leek body portion 30 and the hydrologic control portion 20, is installed on the drip wall 10 of the adobe block B, in particular the hydrological control portion 20 is a waterway hole 12 Installed in the waterway hole 12 to be opened and closed. And the floating portion 30 was to be installed to the top of the waterway hole 12 and the hydrologic control unit 20.

Thus, as shown in Figure 4a, when the height of the initial water is lower than the hydrologic control portion 20, the floating portion 30 is located below the floating portion bracket 35, and also the open control plate of the hydrological control portion 20 (22) and 22 'are also in the closed state.

Since water does not flow downstream, water is gradually filled by the drip wall 10 in the adobe block B, and as a result, the water level is filled with the upper part of the float part 30 as shown in FIG. 30 rises due to the buoyancy of the water. The ropes 31 and 31 ′ connected to one side of the floating body 30 are pulled and tensioned, and thus the front ends of the opening and closing plates 221 and 221 ′ of the open control plates 22 and 22 ′ connected to the other ends. It will work to spread to both sides.

Accordingly, as shown in FIG. 4C, the front of the opening and closing plates 221 and 221 ′ is opened, and water flows through the water flow hole 220, which is a space between the two opening control plates 22 and 22 ′, and gradually the water flow hole. As the amount of water flowing through the 220 and the waterway hole 12 increases, both sides of the opening and closing plates 221 and 221 'are pushed outward, thereby eventually pushing the opening and closing plates 221 and 221' outward. The force pushes the open control plates 22 and 22 'to which the opening and closing plates 221 and 221' are fixed outward. Thus, the open control plate 22, 22 'is rotated about each of the pivot shafts 21, 21', and also the open floating part integrally coupled to the upper part of the open control plate 22, 22 '. 222 is easily rotated upward.

That is, the waterway hole 12 is opened due to the opening of the opening control plates 22 and 22 'which are rotated to both sides as shown in FIG. 4D, so that the water contained in the drip wall 10 flows downstream.

If water gradually flows downstream through the waterway hole 12, and the water level is maintained between the floating body portion 30 and the hydrologic control portion 20 as shown in FIG. 4E, the floating body portion 30 may have a floating body portion. Located under the bracket 35, the tension of the ropes 31 and 31 'is released, but the opening control plates 22 and 22' are floated on the water by the buoyancy of the open floating portion 222 coupled together. In this state, the waterway hole 12 is kept open without being rotated downward. Thus, the water contained continuously flows downstream.

And as the surface height gradually lowers as shown in FIG. 4F, the opening control plates 22 and 22 ′ also gradually descend to the lower side according to the height of the open floating portion 222 by buoyancy of water.

Eventually, when the water level is positioned below the open floating portion 222 as in FIG. 4G, the opening adjusting plates 22 and 22 ′ are rotated about the pivot shafts 21 and 21 ′ and closed. As shown in FIG. 4H, the opening and closing plates 221 and 221 ′ that are rotatably coupled to the opening control plates 22 and 22 ′ are also closed to abut the front ends thereof, through the waterway hole 12 and the water flow hole 220. Water will not flow.

Accordingly, when the waterway hole 12 and the water flow hole 220 are closed by the opening control plates 22 and 22 'and the opening and closing plates 221 and 221', the drip wall 10 of the adobe block B is again. ) And the water is accumulated, and when the water is filled in a certain amount, the water flows again according to the flow in FIGS. 4A and 4B to 4H, and the process is repeated again.

Thus, a certain amount of water is filled with respect to the drip wall 10 of the adobe block B and the flow is repeated again.

The fish control mechanism portion 15 is coupled to the waterway hole 12 is provided with a through member 40 is formed through the water passage through-hole 41, the opening control plate 22, 22 ' The rotating shafts 21 and 21 ′ may be provided to be fixed to one side of the upper portion of the through member 40. As shown in FIG. 10, the through member 40 has protrusions for coupling to both sides of the upper and lower sides, and a channel through-hole 41 is formed in the center, and is coupled to the channel 12 of the drip wall 10. The amount of water flowing can be reduced by flowing the amount of water flowing into the channel 12 through the channel through hole 41. In this case, when the amount of water flowing like a floodwater is large, the waterway through-hole 41 is installed in a state of being removed, but when the through member 40 is coupled to the waterway hole 12, such as a dry season, the waterway through-hole 41 only. Because water flows, the amount of water flowing can be controlled to reduce the amount of water flowing.

Such a through member 40 may be provided such that the hydrologic control unit 20 of the fish control mechanism unit 15 as shown in FIGS. 8 and 9. As such, when the hydrological control unit 20 of the fish control unit 15 is coupled to the penetrating member 40, it is preferable to use it at the time of dry season or where the amount of water flow is small. On the other hand, when there is a large flow of water or a large amount of flow of water, such as a flood, it is preferable to use the water gate control unit 20 directly coupled to the drip wall 10 without the through member 40.

The installation of the penetrating member 40 to adjust the amount of water discharged through the waterway hole 12 formed in the drip wall 10 of the adobe block B as described above is the appearance of the penetrating member 40 and the penetrating member. It should be provided so that the shape of the waterway hole 12 to which 40 is coupled is matched. In the case of forming the drip wall 10 of the adobe block (B), in particular, to be cured by concrete material, when the formwork for the drip wall 10 to install the through member 40 prepared in advance It is preferable to cure the drip wall 10. Thus, when the through member 40 is coupled after the drip wall 10 is completed, the through member 40 and the water hole 12 coincide without gap, so that the amount of water discharged through the water hole 12 is good. It is adjustable.

The adobe block B provided as described above may be provided as a single drip wall 10 in a channel extending along a long side to temporarily block water flowing into the channel so that a predetermined amount of water flows. Therefore, there is always a certain amount of water flowing through the channel.

In addition, as shown in FIGS. 5 to 9, the adobe block B may be manufactured in a block form with a predetermined size and a predetermined length of the side wall. In this way, a plurality of block-type adobe blocks (B) are connected to the downstream from the upstream continuously to be installed. Each of the adobe block (B) may be provided such that the control mechanism unit 15 is coupled to the waterway hole 12 formed in the drip wall 10 as shown in FIG.

Thus, after a certain amount of water is contained in the upstream side block B, and then flows to the next side block B at a time by the fish control mechanism 15, the downstream side block B is obtained again. Previously, the hydrologic control unit 20 of the fish control mechanism unit 15 was in a closed state, and was provided to temporarily send the water to the downstream side due to an increase in the amount of water, and eventually, a plurality of fish blocks (from the upstream to the downstream side) B) It is provided to send a lot of water in order at a time in this order.

When a plurality of adobe blocks (B) is installed in the waterway formed to be inclined to this, as shown in Figs. 6 and 7 to be coupled to a plurality of inclined from the upstream to downstream, the downstream side provided with a drip wall (10) Extending downwards to the bottom is provided with a coupling protrusion protruding.

(6), and the air control mechanism (15) provided with the opening control plate (22, 22 ') on the drip wall (10') of the drop block (4). Thus, the water discharged downstream downstream through the fish control mechanism 15 of the drop block 4, which is the upstream side of the block formed with the engaging protrusion 5, is the fish control mechanism portion of the next drop block 4 'downstream. The water is stored in 15). At this time, since the fresh water block 6 is formed at the same height as the bottom surface of the downstream free fall block 4 ', the water flowing down from the free fall block 4 on the upstream side and the fresh side block 6 on the downstream side Water is accumulated in the next drop block 4 '. In the bottom of the drip wall of the fresh water block 6, a small number of small holes 61 are formed so that water flows to the next drop block 4 'with a small amount of flow.

In this way, the airflow control mechanism of the upstream drop block 4 is opened when the height of the water in the block increases, and the water is discharged downstream, and when the water surface is lowered again, the water control unit 20 of the airflow control mechanism is closed. Discharge is stopped. As such, when the water level of the upstream free fall block 4 is lowered and the discharge is stopped, the working garden body 51 provided in the upstream free fall block 4 is also pulled downward, and the working garden body 51 and the interlocking rope ( 52, the hydrologic control unit 20 of the fish control device of the downstream drop block 4 'which is connected to the open side is opened so that the water contained therein is discharged downstream.

Thus, while water is contained in the upstream adobe block B, the downstream adobe block B stops discharging, and when the upstream adobe block B is discharged, the water level is lowered and the water is automatically downstream. It is provided so that the interlocking operation is made so that the water of the side block (B) is discharged.

Therefore, without having to look at the operating time of the control mechanism of the adobe block (B) is provided so that the water gate is automatically opened and closed.
