Description

ROTARY OPENING-CLOSING TYPE WATER RESERVOIR DEBRIS BARRIER}

The present invention is installed in a valley or river with a large gradient of rivers with a risk of landslides, and prevents the outflow of sediment, and relates to a low-water discharge dam for low sand and water storage.

In general, dams are barriers constructed across streams, valleys, rivers, or estuaries to restrict and manage water flow, and are divided into various types according to their installation purpose, flow control method, materials, design structure and shape, and height. . Among them, if the dam is classified according to the purpose, it can be classified into a reservoir dam, an intake dam, and a four-sided dam.

Reservoir dams are large enough that the inflow from the upstream does not significantly affect the amount of water used, and is used for various purposes such as irrigation, water supply, industrial water, power supply, flood control, fish farming, etc. do. The height of the dam is relatively high, and the dam is often referred to as a reservoir dam.

Intake dams were created to store water at the point of intake for the purpose of watering in rivers, such as water intakes from hydroelectric power plants.Sambang dams are used to prevent large amounts of spilled soils and rocks or driftwood flowing from the mountain area along with the flow of the rivers. It is a low dam installed upstream of the river.

In particular, the four sides dams are installed upstream of the valley where there is a risk of landslides or driftwood and rocks, which prevents the rapid loss of soil and rocks during the peak season. The four-sided dams installed for preventing floods such as mountain valleys also have various types according to their purpose and shape, that is, the slit four-sided dams, buttress four-sided dams, low sands and low-sided water dams.

Buttless four dams have the same function as slit four dams in that they are installed upstream to prevent the loss of driftwood and rocks, but in general, buttless four dams filter driftwood, and slit four dams are the main function. On the other hand, the low sand and low water dams are designed to prevent the outflow of soil during the feng shui season, and to be installed on the downstream side of other four dams.

As shown in FIG. 1, the conventional low water dam has a left dam shoulder 11 and a right dam shoulder 12 symmetrically installed at both sides of the left and right sides, and the left dam shoulder 11 and the right dam shoulder 12. Watertight passage (10) installed between the opposite sides to handle the low sand and water storage, and the concrete on the bottom surface of the downstream side of the left and right dam shoulders (11) (12) and the waterproof passages (12), It comprises a water cushion 20 to receive when the water stored from the upstream side falls beyond the waterproof path 10 to the downstream side.

On the other hand, in the case of the low-water discharge dam with the water cushion 20 as described above to prevent the outflow of soil, and the low sand and water storage function is secured, but the height of the waterproof path 10 is high, the fish can not go upstream from downstream. Therefore, there is a fatal problem that the upstream fish and the downstream fish movement is blocked and the underwater ecosystem is cut off. In order to overcome the problem of disconnection of the underwater ecosystem, as shown in FIG. 2, a water-repellent dam having a slope 30 integrally provided downstream of the waterproof path 10 has appeared. That is, the downstream fish is to be able to move upstream through the waterproof path 10 by riding the inclined surface 31 of the inclined portion (30).

In Korea, in the spring, autumn, and winter, there is no water in the dry season, whereas in summer, the water is plentiful. However, during the summer feng shui season, the water is abundant, so it becomes rainy during heavy rains and floods when the water overflows. Therefore, it temporarily blocks the flow of water flowing from the upstream to the downstream, which causes a sudden earth and sand outflow occurring during the feng shui season through the reservoir.

However, in the case of the conventional general water repellent dam, the waterproof passage 10 is integrally fixed between the left and right dam shoulders 11 and 12, as shown in FIGS. 1 and 2, and functions only in summer feng shui during the year. On the other hand, more time, in the dry season, can only be ugly structures blocking upstream and downstream.

That is, the problem of the conventional water-reserved dam in the prior art, as described above, is responsible only for the feng shui season, and in the dry season it can only be a ugly structure that blocks the upstream and downstream, secondly, during the feng shui season even if it rains during the dry season Unlike the flow of water upstream and downstream, it is impossible to communicate with the fish upstream and downstream at all, and the cleaning work that must be removed because the soil is continuously accumulated in the upstream side of the third waterproofing passage 10 as time goes by and flows downstream. This is necessary separately.

The object of the present invention devised to solve the above problems is not only to perform the low and low water function during the flooding period, but also during a sudden flood, as well as to communicate the fish up and down by communicating the upstream and downstream in the dry season It is to provide a revolving switchgear water-saving dam that does not require separate soil removal work by freeing and allowing the soil accumulated in a sudden flood to flow downstream along with the drainage of water.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments with reference to the accompanying drawings.

In order to achieve the above object, the rotationally-opening water-saving dam in accordance with the present invention is installed symmetrically on both the left and right sides, and a left dam shoulder and a right dam formed with a flow channel so that water flows from the upstream to the downstream between the vertical surfaces facing each other. Between the shoulder and the left and the left shoulder and the right shoulder shoulder is installed to be rotated in a horizontal or vertical direction with respect to the flow channel through the rotation axis, when the horizontal passage parallel to the flow channel and the flow path is opened And, if it is built in the vertical direction based on the flow channel comprises a waterproof road block for closing the flow channel.

In addition, the waterproof low block is formed on the upper side with respect to the rotation axis, the upper weight is made larger than the lower portion to rotate in the horizontal direction by its own weight to look upstream and the lower portion relative to the rotation axis A lower tank which is formed and receives water into a hollow interior, and is formed to protrude on an upper surface of the lower tank based on a state in which the lower tank is laid down in a horizontal direction so as to communicate with an interior of the lower tank; When the water flows through the flow path above the lower tank includes a water hole that is opened so that the water is guided into the lower tank, when the water is received into the lower tank than the upper weight The upper weight is rotated in the vertical direction with respect to the flow channel while the weight of the lower tank is greater do.

The flow channel may include a flooring material having a stepped surface formed to be stepped upstream in an upstream direction on the floor surface, and the lower tank may include a step of the flooring material when the upper weight rotates in a vertical direction based on the flow path. It is characterized in that the rotation is limited by contact with the vehicle surface.

In addition, the upper weight, the horizontal rotation limiting member protruding on the surface facing upstream on the basis of the vertical standing state, the horizontal rotation limitation when the upper weight rotates in the horizontal direction relative to the flow channel The member is in contact with the upper surface of the flooring is characterized in that the rotation is limited.

The rotary switchgear water-saving dam in accordance with the present invention, through the rotational switchgear waterproof road block installed between the left and right dam shoulders not only can perform the low water and water storage during the flooding period, but also during sudden flooding, by communicating upstream and downstream in the dry season It is free to communicate fish up and down, and it is very practical all around because there is no need for separate soil removal work by allowing the sediment accumulated during sudden flooding to flow along the downstream side.

In particular, the waterproof low block is installed between the left and right dam shoulders with the upper weight on the upper side and the lower tank on the lower side, while the weight of the upper weight is made larger and rotates horizontally due to the weight of the upper weight The flow channel is opened, and during the water-season, the lower tank is filled with water through the water hole, and the weight of the lower tank is increased, so that the upper weight is vertically rotated to mechanically manufacture the flow path.

Accordingly, when the waterproofing block is laid in the horizontal direction, that is, during the dry season, the flow channel is opened to freely communicate the fish up and down, and the water flows downstream to discharge the soil as well. In the erected direction, that is, during the water-season period, the runoff can be closed to perform the low sand and water storage functions so as to prevent the outflow of the soil with a sudden flow of water in the downstream direction.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the rotational switchgear type low water dam in accordance with the present invention.

Rotational open and close water-saving dam according to the present invention includes a left dam shoulder 110, the right dam shoulder 120, the flow channel 200, the rotating shaft 300 and the waterproof low block 400 as shown in Figure 3 to 10 It is done by A bottom member 210 is installed on the bottom surface of the water flow passage 200, and the waterproof low block 400 includes an upper weight 410, a lower tank 420, and a water hole 430.

The left dam shoulder 110 and the right dam shoulder 120 are installed symmetrically to both the left and right sides in a valley or landslide with severe loss of soil as shown in FIGS. 3 to 6. The concrete dam is a gravity dam, and is mainly applied to four-side dams for the purpose of low sand and water storage, such as the rotationally-opening water-saving dam of the present invention. However, the concrete dam is not limited to construction materials such as environmentally friendly soil dams, gabion dams and mixed stacking dams. At this time, the flow channel 200 is formed between the left and right dam shoulders 110 and 120 so that water flows from the upstream to the downstream between the vertical surfaces facing each other. The flow channel 200 is a path through which water flows as its name, and the water flowing from the upstream to the downstream blocked by the left and right dam shoulders 110 and 120 is the flow channel 200 between the left and right dam shoulders 110 and 120. Flows through).

3 to 6, the waterproof low block 400 is horizontally or vertically based on the water flow path 200 through the rotation shaft 300 between the left dam shoulder 110 and the right dam shoulder 120. It is rotatably installed in the direction. At this time, when the waterproof road block 400 is laid horizontally parallel to the flow channel 200 as shown in Figs. 3 and 4, the flow path 200 is opened, and the waterproof road block 400 is shown in FIG. As shown in 5 and 6 is closed in the vertical direction with respect to the flow channel 200 in the vertical direction.

When the waterproof low block 400 is erected in the vertical direction, the height of the waterproof low block 400 is formed to be slightly lower than the left and right dam shoulders 110 and 120 as shown in FIGS. 5 and 6, and the flow channel 200 is closed. It is configured to flow downstream only through the waterproof road block 400 lower than the left and right dam shoulders 110 and 120 as the water is stored in the state. If the waterproof low block 400 is formed at the same height as the left and right dam shoulders 110 and 120, the water flowing over the left and right dam shoulders 110 and 120 erodes the left and right shore surfaces. Only through the water will flow. On the contrary, when the waterproof low block 400 is laid down in the horizontal direction, the flow channel 200 is opened as shown in FIGS. 3 and 4, wherein water flows through the flow channel 200 opened upstream and downstream. I can go.

The opening and closing operation of the oil channel 200 by rotating in the horizontal direction or the vertical direction with respect to the water channel 200 of the waterproof road block 400 should be able to be automatically operated by distinguishing the time of the water and the dry season. For example, when the water is abundant, such as in the feng shui season, the water flow path 200 is closed by the vertical rotation of the above-described waterproof road block 400 to prevent the sudden outflow of water by the flow of water to the downstream, In case of lack of water as in the case, the flow path 200 is opened by the horizontal rotation of the waterproofing block 400 to smooth the communication between up and down fishes, and the sediment accumulated during the feng shui season flows slowly with the flow of water downstream. To make it possible.

Through the mechanical coupling relationship between the left and right dam shoulders 110 and 120 and the flow channel 200 of the above-mentioned waterproof low block 400, the waterproof road block to automatically open and close the flow channel 200 at the time of the high and low seasons. Look at the detailed configuration of 400.

The waterproof low block 400 is formed on the upper side of the rotating shaft 300 as shown in Figures 7 to 10, the weight of the upper portion is made larger than the lower portion is rotated in the horizontal direction by its own weight to look upstream Based on a state in which the upper weight 410, the lower tank 420 is formed on the lower side relative to the rotating shaft 300, the water is received into the hollow inside, and the lower tank 420 lying in the horizontal direction It is formed to protrude on the upper surface of the lower tank 420 communicates with the inside of the lower tank 420, the water flows upward from the upstream of the lower tank 420 through the flow channel 200 from the upstream to the downstream In this case, it includes a water hole 430 opened to guide water into the lower tank 420. In this case, when water is received into the lower tank 420, the weight of the lower tank 420 in which water is accommodated is greater than the upper weight 410, and the upper weight 410 is based on the flow channel 200. ) Rotates in the vertical direction.

That is, the waterproof low block 400 is horizontally laid down on the flow channel 200 as shown in FIGS. 4 and 7 when water does not flow from the upstream to the downstream, as in the dry season, or when the water flows in a small amount. State, and the flow passage 200 is open to allow water to flow from upstream to downstream. On the other hand, even during the dry season, when a large amount of water flows from the upstream to the downstream, such as during a sudden flood or particularly during the period of flooding, as shown in FIG. 8, the watertight passage block 400 flows over the waterproof passage block 400 in a state of lying down. I will go. Accordingly, the water flowing upward of the lower tank 420 is received into the hollow interior of the lower tank 420 through the water hole 430. As the amount of water contained in the lower tank 420 increases, the weight of the lower tank 420 and the weight of the received water are combined to exceed the weight of the upper weight 410, and the upper weight 410 is illustrated in FIG. 9. Rotate vertically. However, the moment that the weight of the lower tank 420 and the received water rotates the upper weight 410 completely vertically is not necessary. Because, even if the water contained in the lower tank 420 rotates the upper weight 410 to some extent in the vertical direction, the upper weight by the force in the downstream direction according to the flow of water flowing from the upstream to the downstream as shown in FIG. This is because 410 can be rotated in a completely vertical direction. As the upper weight 410 is completely rotated in the vertical direction, the water flow passage 200 is closed, and the waterproof road block 400 is capable of performing low and low water storage even during a sudden flood.

On the other hand, there is a need for a configuration capable of maintaining a horizontal state and a vertical state during the horizontal rotation and vertical rotation of the water flow path 200 of the waterproof road block 400. To this end, as shown in Figures 3 to 10 to form a horizontal rotation limiting member 411 of the stepped surface 211 and the upper weight 410 formed on the bottom member 210 of the flow channel 200.

The water flow path 200 includes a flooring material 210 having a stepped surface 211 formed on the bottom surface in an upstream direction, and the lower tank 420 has the upper weight based on the water flow path 200. When the 410 rotates in the vertical direction, the contact is caught by the stepped surface 211 of the flooring 210 so that rotation is limited. That is, as shown in FIGS. 6 and 10, when the upper weight 410 rotates in the vertical direction, the lower tank 420 comes into contact with the stepped surface 211 of the flooring material 210 and is caught, thereby waterproofing the block ( The vertical rotation of the 400 is limited to maintain the vertical state.

On the contrary, the upper weight 410 includes a horizontal rotation limiting member 411 protruding on a surface facing upstream with respect to the vertical state, and the upper weight 410 is based on the flow channel 200. When rotating in the horizontal direction, the horizontal rotation limiting member 411 is in contact with the upper surface of the bottom member 200 is limited to the rotation. That is, when the upper weight 410 rotates in the horizontal direction, as shown in FIGS. 4 and 7, the horizontal rotation limiting member 411 in which the upper weight 410 protrudes is in contact with the upper surface of the flooring material 210. Therefore, the horizontal rotation of the waterproof low block 400 is limited to maintain a horizontal state.

As described above, the rotationally open / closed water-repellent dam according to the present invention may perform the low-loss and water-storage functions through the water-opening / waterproof flood block 400 installed between the left and right dam shoulders 110 and 120 even during sudden flooding. In addition, during the dry season, it is possible to communicate upstream and downstream to freely communicate fish between upstream and downstream, and to allow the sediment accumulated during sudden flooding to flow downstream along with water draining, thus eliminating the need for separate soil removal. .

In particular, the waterproof lower block 400 is installed between the left and right dam shoulders 110 and 120 with an upper weight 410 on the upper side and a lower tank 420 on the lower side, while the upper weight 410 is installed. ) To make the weight larger and rotates in the horizontal direction by the weight of the upper weight 410 to open the water flow path 200, and when the feng shui season, the water through the water hole 430 in the lower tank 420. As the weight of the lower tank 420 is increased while filling, the upper weight 410 is rotated in the vertical direction to naturally produce the mechanical flow path to close the water flow path 200.

Accordingly, when the waterproof low block 400 is laid in the horizontal direction, that is, during the dry season, the flow channel 200 is opened to freely communicate the fish up and down, and the water flows downstream so that the soil may be discharged together. On the contrary, when the waterproof road block 400 is erected in the vertical direction, that is, during the water-sealing period, the water flow passage 200 may be closed to perform low sand and water storage functions to prevent the soil leakage with the rapid flow of water in the downstream direction.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
