Description

Guide water supplying device for fish road

The present invention relates to a device for supplying a manned water for supplying a fish manned water to the fishery when the fishery is installed in repair facilities such as dams or beams installed in rivers or rivers.

More specifically, even when there is a lack of water in a repair facility or when there is water, even when there is not good water quality (temperature, turbidity, etc.) of the manned water from the upstream, the manned water of the estuary can always supply high quality manned water to the fish. It relates to a supply device.

In general, fishing facilities such as dams and beams installed in rivers or rivers are installed.

In other words, according to related laws and regulations such as the Water Resources Protection Ordinance, when installing hydraulic structures that block rivers, the mandatory fishery is mandatory for the preservation of ecosystem and the smooth movement of fish.

However, most of these dams and beams cannot be installed because of lack of river water, and even if they are installed, the time to operate the fish is not only a dry season but also overlaps with the period of heavy water use. In most cases, it is not running.

However, in the case of dams, if it is impossible to install fish, it is not necessary to install fishes by installing habitats such as artificial spawning grounds instead of fish.

If you look at the technical problems associated with water,

(1) Since the dam is small and there is not much water storage, it is impossible to send extra water to the fishery,

(2) Even though water can always be sent like a power generation dam, fish are not attracted because the water temperature is low due to taking deep water and discharging it into power generation water.

(3) Even if the surface water is taken out and discharged to the stream maintenance water, the water in the reservoir rises later than the stream, so that fish do not collect in the fishery.

(4) Fish are not attracted to fish due to rapid water quality difference between water flowing out of the fishery and river water.

In more detail in relation to the above (1), it is difficult to send extra water to fish because the dam is usually used for agricultural water because of its small capacity.

In other words, if a dam with a 2m-wide cascade is installed, the amount of fish needed to maintain it should be at least 0.1㎥ / s, which requires about 800,000㎥ of water for three months from April to June. do.

However, during this period, it is difficult to send water to the fishery because it is a dry season and there is almost no inflow.

In Korea, out of 17,913 pre-built agricultural reservoirs (2001 Annual Statistics on Agricultural Production Base Maintenance), 15,915 reservoirs with less than 1 million m3 of effective reservoirs accounted for 89% of the total, and more than 10 million reservoirs had 37 It is just a point.

If fish oil maintenance is at least 800,000㎥ for three months, 89% of the agricultural reservoirs in Korea are low enough for fishery water, and less than 10 million㎥ is 99.8%, so 99.8% of agricultural water dams in Korea cannot install fishes because of insufficient water. It is true.

It is difficult to operate the island because the water demand drops from April to June due to the concentration of water over 10 million ㎥, the remaining 0.2%.

In relation to paragraph (2), even if there is water to be discharged, such as multi-purpose dams or power generation dams, most dams take in deep water and generate power, so that the water temperature is low (not suitable for attracting fish). Releasing the water causes the fish to gather to the side where the water is not released.

Moreover, in the case of large dams, the deep water maintains about 13 ℃, which is similar to the average temperature in the region annually, so it is warmer than river water in winter, but in spring, the water rises above about 20 ℃, while the discharge water maintains about 13 ℃. The fish avoids this.

According to Dissipation (1967), the activity of river fish such as sweetfish, carp, trout, and salmon is directly proportional to the water temperature. Especially, the eel responds very sensitively to the change of 0.5 ℃, and the water temperature is gathered up.

In addition, the small water phase of anadromous fish such as sweetfish and eel usually starts when the temperature of the river water is higher than that of the sea, so the low water temperature of the river is inadequate for the movement of fish.

Regarding paragraphs (3) and (4), in the case of large dams, even if the surface water is taken out and discharged into the fishery manned water, the water in the large reservoir will rise later than the shallow river water, so that the fish will not collect in the fishery. Inappropriate as drinking water.

In addition, when the surface water of the dam or reservoir is used as fishery water, the cost of pumping the surface water is high, and this also has a disadvantage that the temperature problem cannot be fundamentally solved.

The present invention has been devised to solve these problems, and its technical task is to pump the river water downstream of the dam and supply it to the fishery, thereby reducing the effects of water scarcity, water temperature, and water quality, and reducing the effects of water damage on all types of fish. It is to provide fisherman's manned feeder that can be installed and operated.

※ Explanation of code for main part of drawing

10 dam 20 river

30: degree 40: waterway

50: pump 60: pick up tank

In order to achieve the above object, the present invention forms a waterway between a stream downstream of a dam and an inlet of an estuary or a catchment tank, installs a pump in the waterway, pumps the river water with a pump, and discharges it as a manned water at the outlet of the eido. To do so.

In this way, the present invention solves the water shortage by pumping the river water downstream of the dam by pumping the fish, and the fish can be attracted by reducing the influence on the small injuries resulting from the difference between the water temperature and the water quality.

In addition, it can be installed and operated effectively in all types of fish, and has the advantage of excellent fish attraction effect at low cost.

In addition, since the deep water or surface water in the dam is not used, the stream water discharged downstream of the dam is pumped and supplied to the fishery, so that the water temperature and water quality are suitable to be used as the inducement of the fish, which causes the fish to gather toward the fishery.

When described in more detail based on the drawing of the attached embodiment of the present invention the supply device as follows.

1 and 2 are a schematic side cross-sectional view and a plan view of the water supply, and Figs. 3 and 4 show a schematic side cross-sectional view and a plan view of the operated feeder.

As illustrated, in the case of a waterway type such as a stepped manner, a water channel 40 is formed between the stream 20 downstream of the dam 10 and the outlet of the fishery 30, and the pump 50 is installed in the water channel to provide the river water. After pumping with the pump 50, it is discharged to the outlet of the fishery 30.

In the case of the operation type, it refers to an operation type fishery in the form of an elevator or a traction type fish tank 60, the fish tank 60 is pulled up and poured into an upstream dam, in this case, the upper side of the tank 60 By installing a water channel 40 provided with a pump 50 between the lower side and pumping the river water with the pump 50 to discharge to the upper side of the water tank (60).

In the case of the channel, the manure water is pumped from the stream 20 having high water temperature and discharged near the outlet of the fishery 30 so that the river water always has high water temperature.

At this time, the discharge position of the pumped water may be discharged to the outlet of the fishery 30 in the case of a staircase or a channel, and the Borland type is discharged to the lower pool.

In the case of the operation type, the fish are collected in the sump tank 60 such as an elevator or a traction type, the tank is pulled up, and poured into an upstream dam, so that the river water is discharged into the manned water supply tank 70 above the sump tank 60. Just do it.

By pumping a single 20 kW pump 50 to a beam of about 1 m head through the above apparatus, a flow rate of approximately 0.1 m 3 can be sent to a stepped fishery 30 having a width of 2 m at a flow rate of 0.5 m depth of 10 cm.

At this time, the power consumption is 480 ㎾ / h per day, and the rate is about 1000 won when using agricultural electricity, so even if the water pump is operated for three months, it is possible to operate the airway 30 if the electricity rate is about 100,000 won. have.

As described above, the present invention pumps river water upside down and supplies it to the fishery, so that the fish can be effectively operated by installing the fishery in the dam, which is small in size, such as agricultural water dams, and which lacks water.

In addition, where a lot of water is discharged, such as a hydroelectric power plant, where water is cold and fish are not attracted, the water for the power plant can be used as repellent water, and the hot water river water can be discharged to the fishery to attract fish to the fishery.

And when the fish can not be installed in the outlet of the river maintenance water in the topography, the fish can be installed in a position completely different from the drainage path and can be injured in the epoch.

In addition, when the manned water is supplied by the present invention, there is no additional water, and thus, the existing dam may be installed in all existing dams.
