Technical field

The present invention relates to a kind of Fishway block.More specifically, the present invention relates to be installed in the Fishway block on dam, embankment or the reservoir, thus the speed of the current that are used to slow down and make fish swim across dam, waterfall, culvert and other obstructions can easily to move to upstream or downstream.

Background technology

Usually, fish pass need be installed in transverse structure on the transversary as dam or horizontal dam of river, brook, streams or other water channels.According to Korea S's fishery conservation method, fish pass need to be installed with the protection ecosystem, and in the time of the transversary that makes up across river or streams, to be allowed the fish migration, with reference to inland fishery method implementing regulations, it relates to forbids that fish pass stops.

Simple in structure according to traditional fish pass that the fishery conservation method is installed, it is installed on dam or the horizontal dam to allow water to flow to the downstream by dam or horizontal dam.

Summary of the invention

The tradition fish pass is simple in structure, allows water to flow to the downstream by the barrier structure as dam or horizontal dam from the upstream in river.Therefore, although a kind of possibility be when water-head excessive or water-head is very little and under the situation that water velocity is too high fish can not move to the upstream along traditional fish pass.

Therefore, the fish residence point that can install on dam as the fish spawning pond substitutes fish pass.Yet, rainy season water level can increase suddenly and surpass safety level, make the water of thousands of tons drain from dam, cause fish is occupied the breaking-up of point.In a word, because relevant technology barrier, traditional fish pass is ineffective.

In order to realize top purpose, according to an aspect of the present invention, provide a kind of Fishway block, comprising: base plate; Be installed in the described base plate sidewall paneling on the side separately in parallel with each other; And being arranged on a plurality of demarcation strips on the described base plate, each described demarcation strip extends to another sidewall paneling from one of described sidewall paneling, and each demarcation strip has the limbers; Wherein, the position of the described limbers of each demarcation strip forms zigzag, and the size near the described limbers that near the size of the described limbers that forms the corresponding demarcation strip lower end forms less than the upper end at corresponding demarcation strip slows down in order to the flow velocity that will introduce the water in the compartment that forms between each adjacent separator plates.

According to a further aspect in the invention, provide a kind of Fishway block, comprising: base plate; Be installed in the described base plate sidewall paneling on the side separately in parallel with each other; And being arranged on a plurality of demarcation strips on the described base plate, each described demarcation strip extends to another sidewall paneling from one of described sidewall paneling, and each demarcation strip has the limbers; Wherein, form zigzag, make that the current of introducing in the described compartment that forms between the described demarcation strip are slowed down, and water compiles and is stored in the described compartment that forms between the described demarcation strip in the position of vertical direction and the above limbers of horizontal direction.

In accordance with a further aspect of the present invention, provide a kind of Fishway block, comprising: base plate; Be installed in the described base plate sidewall paneling on the side separately in parallel with each other; And being arranged on a plurality of demarcation strips on the described base plate, each described demarcation strip extends to another sidewall paneling from one of described sidewall paneling, and each demarcation strip has the limbers; Wherein, described demarcation strip has fish pass size Control mechanism, is used to adjust the size of limbers, each limbers be allow fish pass through and upstream with the passage of downstream migration.

At first, Fishway block comprises transverse to the river and has one or more demarcation strips of limbers separately that the limbers of demarcation strip is immersed in the water, makes that the water velocity in the water channel slows down.As a result, also can easily upstream move even have the fish of weak swimming ability by this Fishway block with the downstream.

The second, described Fishway block comprises base plate, sidewall paneling and demarcation strip, since very heavy, so they can prepare separately, make described Fishway block can easily assemble, dismantle and under disassembly status, transport.

The 3rd, the described Fishway block current that can slow down, and reduce the water yield that flows through fish pass, because the position of the limbers on the demarcation strip is different with size.And described Fishway block can reduce the loss of retaining in the reservoir.

The 4th, described Fishway block comprises fish pass size Control mechanism, is used to adjust the size of fish pass, the size of limbers on the demarcation strip just, and fish can upstream move with the downstream by the limbers; And level controling mechanism, be used for being adjusted at the water level of the water that the compartment that forms between the adjacent separately demarcation strip stores, even the size by adjusting the limbers of demarcation strip separately and adjust the water level that is stored in the water in the described compartment, make that very a spot of water is introduced in the described compartment, also can remain on the water level of the water of storing in the compartment that forms between the adjacent separately demarcation strip.Therefore, described Fishway block can dynamically adapting environment change the water velocity in river, and keeps fish pass always open, even the discharge that flows into Fishway block seldom.

The 5th, described Fishway block further comprises the place ahead that is arranged in the foremost demarcation strip or is arranged in current deceleration part between the adjacent separator plates, flow into water velocity in the described Fishway block in order to main reduction, even can allow the weak fish of swimming ability easily to pass through by this.

The 6th, described Fishway block is included in sidewall paneling, demarcation strip and the lip-deep heater of current deceleration part, is used to prevent winter or at the cold district water freezing, prevents that by this described Fishway block is by bursting by freezing.

Can be clear by top description, Fishway block according to the present invention has following advantage.

At first, the position of the limbers on the adjacent separator plates changes, and that is to say, the height of the position of limbers has zigzag and arranges.And current deceleration part is between demarcation strip the place ahead, foremost and demarcation strip.By these structures, water velocity significantly reduces, because water flows after water temporarily stores between the adjacent separator plates in the compartment, even make the weak fish of swimming ability also can upstream move with the downstream.

The second, when water overflow along near the upper end that is formed with the demarcation strip of limbers the demarcation strip lower end, the water that is stored in the downstream part intermittently landed, and produces bubble by this.The result provides sufficient oxygen for the biology in the water, and set up microorganism can survival environment.

The 3rd, because demarcation strip and sidewall paneling have draw ring separately, therefore described Fishway block is installed easily.And adjacent Fishway block makes described Fishway block to install easily and securely to be fixed on the installation surface by the bolton combination.

The 4th, under the situation that sidewall paneling and demarcation strip are prepared respectively to install then, described Fishway block is easily from the haulage truck loading and unloading, and can effectively transport.And owing to can locally replace, the maintenance of Fishway block is easy.

According to the principal character of Fishway block of the present invention is to keep water velocity constant and slow down, and upstream moves with the downstream to allow the fish a little less than the swimming ability.

And, because described Fishway block has the heater of the selection part that covers sidewall paneling, demarcation strip and current deceleration part, prevented because the Fishway block bursting by freezing that causes at cold snap or cold district water freezing.

Below, will the mounting method of above-mentioned Fishway block be described.

With reference to figure 5, pipe 26 is installed in 25 belows, horizontal dam, is lower than the lowest water level in the reservoir, and one or more Fishway block 10 is attached to an end of the pipe 26 on the downstream on horizontal dam 25.In this case, the element task that Fishway block 10 is installed is to finish on the inclined-plane on the horizontal dam in downstream.Yet if horizontal dam is made by concrete, so extra element task not necessarily.

Then with reference to figure 6, rope 30 passes the draw ring 19 of

demarcation strip

15a, 15b and 15c, and rope by crane 31 pull-ups promoting

demarcation strip

15a, 15b and 15c, on the inclined-plane in order to the downstream that

demarcation strip

15a, 15b and 15c is installed to horizontal dam 25.In this case, two or more Fishway blocks 10 are contacted, and make water (flow) direction identical with the length direction of Fishway block 10.

Some Fishway blocks 10 can be transported to the job location and pile up in stack region.Because Fishway block 10 is very heavy, therefore be difficult to use manpower transportation Fishway block 10.Therefore, Fishway block 10 is transported to the infield by the jumbo as the crane from piling up the place, installs then.

The Fishway block 10 of An Zhuaning is bonded to each other in some way in the above described manner, that is, be arranged on the demarcation strip 15a of end of sidewall paneling 14a in

first Fishway block

10 and 14b and 15c any depression 21 and another projection 22 engagements of the demarcation strip 15a of second Fishway block 10 and 15c.When the projection 22 of demarcation strip 15c was inserted the depression 21 of demarcation strip 15a, limbers 16a and 16c and through hole 23 alignd in a straight line.

After Fishway block 10 connected, the bolt 24 that is used as linkage was inserted into the through hole 23 that passes

demarcation strip

15a and 15c and keeps the tight of Fishway block 10 to be connected, and made Fishway block 10 combine and integral body of picture.More fastening if desired connection can provide anchor at the base plate 13 of Fishway block 10 or the bottom of

sidewall paneling

14a and 14b.

After Fishway block 10 was installed, the pipe 26 that is installed in the lowest water level below in the reservoir was opened to allow water to flow to the downstream by managing 26.At this moment, the drainability of pipe 26 is equal to or greater than the drainability of limbers 16a and 16c.The drainability of pipe 26 is controlled, the feasible upper end that can flow through demarcation strip 15a from the water of managing 26 dischargings.

After Fishway block 10 was installed, if water flows to the downstream by managing 26 upstream sides from horizontal dam 25, water was stored in the compartment that forms between

adjacent separator plates

15a, 15b and the 15c.As a result, water is crossed

limbers

16a, 16b and 16c with low-speed flow.Therefore, because Fishway block 10, the fish in downstream can be moved to the upstream along the water channel on inclined-plane.

Especially, though

demarcation strip

15a, 15b that the fish with weak swimming ability also can be by

Fishway block

10 and 15c downstream and upstream migration.

With reference to figure 5, Fishway block 10 is installed on the inclined-plane on horizontal dam 25, and height and the horizontal level of limbers 16a, the 16b of separately

demarcation strip

15a, 15b and 15c and 16c differ from one another.That is to say that limbers 16a, 16b and 16c are with Z-shaped layout.The position of the limbers 16b of intermediate section dividing plate 15b and size is lower than and less than

other limberss

16a and 16c, but be arranged in intermediate section dividing plate 15b rear side demarcation strip 15c limbers 16c the position and size is higher than and greater than position and the size of the limbers 16b of demarcation strip 15b.That is to say that limbers 16b and 16c form ladder.

Therefore, under the limbers of demarcation strip 15a 16a is immersed in state in the water, from the water of managing 26 dischargings can be only limbers 16b by demarcation strip 15b flow to the downstream.That is to say that the water that flows to the downstream by limbers 16b temporarily is separated plate 15b to be stopped, forms and refluxes, be temporarily stored by this, and the limbers 16b by demarcation strip 15b flows to the downstream then.

Limbers 16c is arranged on the position that is higher than limbers 16b.Therefore, be stored in the compartment between demarcation strip 15b and the 15c if flow out the water of limbers 16b, limbers 16b is immersed in the water, makes current slow down.The difference of the water level of the water of storing in the water level of the water of storing in the compartment of hydraulic pressure basis between

demarcation strip

15a and 15b and the downstream compartment between

demarcation strip

15b and 15c produces.The influence of hydraulic pressure water velocity.Therefore, along with hydraulic pressure reduces, water velocity slows down.

Therefore, because a spot of water flows through the limbers 16b of demarcation strip 15b, it is similar to be stored in water in the upstream side compartment between demarcation strip 15a and the 15b water interior with being stored in downstream compartment between demarcation strip 15b and the 15c.At this moment, owing to flow through the water of upstream side limbers 16a more than the water that flows through limbers, downstream 16b, water level between demarcation strip 15b and the 15c in the compartment causes the water overflow to cross demarcation strip 15b owing to excessive water increases, and the water of overflow is introduced in the compartment between demarcation strip 15b and the 15c by this.

According to above-mentioned operating principle, because water is stored and is blocked in the compartment between

demarcation strip

15a, 15b and the 15c, and the speed that flows through the water of

limbers

16a, 16b and 16c significantly reduces, and also can upstream move with the downstream through

limbers

16a, 16b and 16c by horizontal dam 15 even have the fish of weak swimming ability.

In the superincumbent description, Fishway block 10 is realized as finished product.Yet Fishway block 10 can be used as individual component and realizes, comprises base plate 14,

sidewall paneling

14a and 14b and

demarcation strip

15a, 15b and 15c.The element of Fishway block 10 is transported to the infield respectively, and uses crane assembling and installation.Because Fishway block 10 is prepared under the state that is divided into base plate 14,

sidewall paneling

14a and 14b and

demarcation strip

15a, 15b and 15c, the weight of Fishway block 10 also is separated, and therefore compares easier loading, transportation and unloading Fishway block 10 with the Fishway block 10 of handling integral body.

demarcation strip

15a, 15b and 15c and

sidewall paneling

14a and 14b all has vertically profiling.With reference to figure 8, the upper end of each

demarcation strip

15a, 15b and 15c is crooked in one direction, have a projection 28 by this, this projection is upstream outstanding, with when Fishway block 10 is installed on the relatively gentle slope with

demarcation strip

15a, 15b and 15c between the water level maximization of retaining in the compartment.

According to Fig. 7 and embodiment shown in Figure 8, even the horizontal dam that Fishway block is mounted thereon has relatively gentle slope, be stored in the water yield in the compartment between

adjacent separator plates

15a, 15b and the 15c also owing to vertically disposed

demarcation strip

15a, 15b and 15c and be positioned at separately that the projection 28 of the upper end of

demarcation strip

15a, 15b and 15c maximizes.By this structure, the operating effect and the advantage of Fishway block 10 have strengthened.

Fishway block 100 comprises current deceleration part 300, is arranged in top demarcation strip 151 fronts or the compartment between adjacent separator plates 151 and 152,152 and 153 or 153 and 154.Current deceleration part 300 can at first slow down the current that enter demarcation strip 151,152,153 and 154, and current deceleration part 300 is preferably configured as stairstepping, and arranges against water (flow) direction.

Another embodiment according to the present invention, with reference to Figure 16, the water of Heng Ba upstream mainly slows down by colliding with the current deceleration part that is installed in top demarcation strip 151 the place aheads, and the limbers 161 on the demarcation strip 151 is immersed in the water then.After limbers 161 was immersed in the water, water only flow in the compartment between

demarcation strip

151 and 152 downstream by limbers 161.Flow to the water of

demarcation strip

152 and 301 collisions of current deceleration part, the temporary transient backflow, and be stored in then in the compartment between

demarcation strip

151 and 152, make water velocity slow down rapidly, and water flow through the limbers 162 of demarcation strip 152 towards demarcation strip 153.

In this case, because limbers 163 is arranged on the position higher than the upper end of demarcation strip 152 or limbers 162, along with flowing through limbers 162 and water towards demarcation strip 153, water is stored in the compartment between

demarcation strip

152 and 153, limbers 162 is immersed in the water after a time, causes water velocity to slow down.That is to say that owing to the hydraulic pressure that the water-head corresponding to the water in the compartment between the water in the compartment between

demarcation strip

151 and 152 and

demarcation strip

152 and 153 produces, the current that flow through limbers 162 slow down.In this case, because greater than the water yield that flows out this compartment by the limbers 162 of demarcation strip 152, water yield official post gets the increase of the water level in the compartment between

demarcation strip

152 and 153 by the water yield in the compartment between the limbers 161 introducing demarcation strips 151 and 152 of demarcation strip 151.

In this case, if introduce between the

demarcation strip

151 and 152 in the compartment and between

demarcation strip

152 and 253 water yield in the compartment very little, limbers 162 and 163 can not be immersed in the water so, makes fish pass not form.In this case, the fish pass size Control mechanism and the level controling mechanism that are installed on sub-demarcation strip 251,252,253 and 254 are controlled, make a large amount of water be stored in the compartment between adjacent separator plates 251,252,252 and 254, make limbers 161,162,163 and 164 be immersed in the water fully, and a small amount of as far as possible water flow through limbers 161,162,163 and 164.

The operation of fish pass size Control mechanism will be described below.At first, be installed in first and

second bevel gears

264 and 276 rotations on the top of limbers 161,162,163 and 164, make the first and second vertical stand-up

spares

263 and 274 of first and second sluice 262 and 267 move up and down, adjust the size of limbers 161,162,163 and 164.As mentioned above, because it is very little to introduce the water yield of Fishway block, first and

second sluice

262 and 274 are progressively closed limbers 161,162,163 and 164, make demarcation strip 251,252,253 and 254 limbers 161,162,163 reduce relative with 164 size.

That is to say that because limbers 161,162,163 and 164 parts close, and the water yield of stream is very little downstream, so water is stored in the compartment between the adjacent separator plates 151 and 152,152 and 153 and 153 and 154.As a result, limbers 161,162,163 and 164 is immersed in the water fully.In this case, even water collects in the compartment between

demarcation strip

152 and 153, limbers 161 that also might demarcation strip 151 not exclusively under water.Therefore, the height of

demarcation strip

252 and 254

water channel groove

255 and 256 bottom is controlled by using level controling mechanism, makes the limbers 161 of demarcation strip 151 be immersed in the water fully.

The class of operation of the operation of level controling mechanism and fish pass size Control mechanism seemingly, difference is that the height of the bottom of

water channel groove

255 and 256 is adjusted by moving up and down the 3rd sluice 273, rather than moves first and second sluice.

As mentioned above, the size of limbers 161,162,163 that might be by adjusting demarcation strip 251,252,253 and 254 and 164 size and

water channel groove

255 and 256 is immersed in the

limbers

161 and 163 of

demarcation strip

251 and 253 in the water, the limbers 161,162,163 and 164 of demarcation strip 251,252,253 and 254 all can be immersed in the water by this.

Therefore, because the water yield of compartment between the demarcation strips 251 and 252 is flowed out less than the water yield of introducing compartment between the demarcation strips 251 and 152 by the limbers 161 of demarcation strip 251 in the limbers 162 by demarcation strip 252, so the water yield of compiling in the water yield of compiling in the compartment between

demarcation strip

152 and 153 and the compartment between

demarcation strip

253 and 254 is identical.And, because the water yield of limbers 161 that flows through demarcation strip 251 is greater than the water yield of the limbers 162 of flowing through demarcation strip 252, the difference of the water yield has increased the water level in the compartment between the

demarcation strip

151 and 152, be stored in water in this compartment by this finally by the water channel groove 255 that the is formed at demarcation strip 252 upper ends demarcation strip 152 that overflow, and be introduced in the compartment between

demarcation strip

152 and 153.

By means of above-mentioned Fishway block operating principle, because water compiles and is stored in the compartment between the adjacent separator plates 151 and 152,152 and 153 and 153 and 154, the current in the limbers 161,162,163 and 164 of demarcation strip 251,252,253 separately and 254 greatly slow down.Therefore, also can upstream move even have the fish of weak swimming ability, especially by limbers 161,162,163 and 164 by Fishway block with the downstream.

Figure 17 shows the Fishway block according to one embodiment of the present invention.With reference to Figure 17, flake heater covers current deceleration part 301,302,303 and 304 partially or entirely, demarcation strip 251,252,253 and 254 and

sidewall paneling

141 and 142, in order to preventing the Fishway block bursting by freezing, in water freezing, can cause the bursting by freezing of Fishway block in winter or at cold district.The carbon fiber heaters that heater is preferably made in some way, be that ultrafine carbon fiber, protofibre are plain and high-purity chemical combination ceramic powders is mixed, mixture uses the directional profile technology to be processed to the thick or thinner special thin slice of 1mm, and pair of electrodes forms and be coated with insulation materials on thin slice.

By heater, when winter or the lasting cold of cold district weather, water can not freeze in Fishway block, makes that Fishway block can be by bursting by freezing in severe cold weather.

As mentioned above, the bottom level of the water channel groove that the size of the limbers on the demarcation strip and the upper end of demarcation strip form is adjusted, and makes current suitably slow down.And the distance between the demarcation strip also can be adjusted, and makes current suitably slow down.Moreover the height that is arranged on the current deceleration part between the demarcation strip can be adjusted with the current that slow down.

In the superincumbent description, Fishway block is installed on the inclined-plane in downstream on horizontal dam.Yet,, also can realize same operation and effect even Fishway block is installed in the brook with flat and torrent and the side in river valley.
