Description

Technical Field

[0001] Embodiments of the present invention relate to a fish collection device for fishway surveys that can be adjusted in size according to the intervals of fishways, is easy to carry, causes no damage to the collected fish, and facilitates the collection of fish. Background Art

[0002] Fishways are installed on artificial structures such as dams and weirs built in rivers to facilitate the movement of fish.

[0003] Fishways that meet the functions in the fishways are easy to model and degrade fish, and the fish can move easily without any damage.

[0004] At this time, whether the installation of the fish is in place can be evaluated by collecting the fish described in detail using a fish collection device.

[0005] That is, through the fish collection device, the number and species of the captured fish and whether they are damaged can be confirmed, so as to measure whether the installed fish meets the functions.

[0006] However, existing fish collection devices for fish surveys have the following disadvantages:

[0007] First, existing fish collection devices have a fixed size and are difficult to install even if the intervals are different.

[0008] Moreover, existing fish collection devices are large in volume and difficult to carry.

[0009] In addition, existing fish collection devices are difficult to collect fish due to their narrow entrances, and there is a problem that the fish are easily damaged during the process of taking out the fish.

[0010] Moreover, existing fish collection devices with zippers need to be removed every time when confirming the fish to identify the species of fish.

[0011] In addition, existing fish collection devices are installed at the lower end of the fish island exit. The individuals that are finally successfully modeled by the fish island are not captured. For the degraded fish, it is impossible to be sure to specifically use the installed fish island, so there is a problem that the result accuracy decreases.

Figure 7 is schematically represented Figure 5 The concave part plan view of the induction net adjustment unit of.

[0062] As Figure 1 shown, according to an example of the present invention, the fish collection device 100 for fishway investigation can be set to a number corresponding to 10 fishway exits.

[0063] That is to say, as shown in this embodiment, if there are 2 exits of the fish island, they can be respectively installed in the exits 10 of each fish island, but not limited to this. If there is 1 exit of the fish island, one can be installed corresponding to the exit of the fish island.

[0064] At this time, the fish collection device 100 for fish island investigation in this embodiment is installed at the fish island exit 10, and the width of the front frame forming the fish inflow entrance can be adjusted and set according to the interval of the fish island exit 10, so it is applicable to fish islands with various exits.

[0065] More specifically, if referring again to Figure 2, according to an embodiment of the present invention, the fish collection device 100 for fishway investigation can be disassembled to correspond to the interval G between the fishway exit 10 and the exit 10, and the first and second front frames 111 and 112 with adjustable overall length in a video - viewing manner and each unit of the first and second front frames 111 and 112, together with the first, second, second frames 111, second frames, form the space of the second, second, second frames 112, second frames and second frames 111, second frames 112. A fish inlet 130a is connected to the second side frame 122, and it may include a collection bucket 130 forming a fish collection space S2 flowing into the manned space S1 and a flow channel net 140 located between the first and second side frames 121 and 122, guiding the fish flowing into the manned space S1 to the side of the fish inlet 130a of the collection bucket 130.

[0066] Among them, as Figures 3 to 5 shown, each of the front frames 111 and 112 and each of the side frames 121 and 122 may include vertical frames 112, 112c, 122c connecting upper frames 111a, 112a, 121b, 122b and end frames 111, 112, 112, 112, 112c of upper frames 111a, 112a, 121a, 122a, 111b, 112b, 121b, 121b.

[0067] That is to say, the upper frame 111a, lower frame 111b and vertical frame 111c of the first front frame 111, and the upper frame 112a, lower frame 112b and vertical frame 112c of the second front frame 112 are overall square - shaped, and can form the entrance part where fish initially flow into the fish attraction space S1.

[0068] Moreover, the upper frame 121a, lower frame 121b and vertical frame 121c of the first side frame 121 are also overall square - shaped with the vertical frame 111c of the first front frame 111, and can form a part of the fish attraction space S1.

[0069] At this time, on one side of the square formed by the first side frame 121, the diversion net 140 can be connected and installed or an individual net frame 145 can be installed separately.

[0070] In addition, the upper frame 122a, lower frame 122b and vertical frame 122c of the second side frame 122 are also overall square - shaped with the vertical frame 112c of the second front frame 112, and can form the other side part of the fish attraction space S1.

[0071] At this time, a separate net 125 can be formed on the other side of the quadrilateral formed by the second side frames 122, and an opening 125a connected to the fish inlet 130a of the collection bucket foot 130 can be formed on the net 125.

[0072] In this regard, the fish attracted to the attraction space S1 can move through the opening 125a connected to the fish inlet 130a into the collection space S2 inside the collection bucket foot 130 for collection.

[0073] In addition, the first and second front frames 111 and 112 can be installed by adjusting and integrating the lengths in a mutually visual manner according to the spacing G at the fish island exit 10.

[0074] For example, when the upper and lower frames 111a and 111b of the first front frame 111 are partially inserted inside the upper and lower frames 112a and 112b of the second front frame 112, they can be extracted and inserted outside or inside the upper and lower frames 112a and 112b of the second front frame 112.

[0075] In this regard, according to the spacing G at the fish island exit part 10, based on the upper and lower frames 112a and 112b of the second front frame 112, the lengths of the upper and lower frames 111a and 111b of the first front frame 111 can be extended or shortened, and the first and second front frames 112 can be provided on the wall surfaces of the two side walls of the fish island exit part 10 with different spacings, that is, the two side complements ( Figure 1 ).

[0076] At this time, the upper and lower frames 111a and 111b of the first front frame 111 are inserted into the upper and lower frames 112a and 112b of the second front frame 112, and the overlapping parts may respectively be provided with locking units 150 for restricting or releasing relative movement. Of course, it is not limited to this, and the locking unit 150 may be provided only in any one of the upper and lower frames 111a and 111b of the first front frame 111 and the upper frame 112a or the lower frame 112b of the second front frame 112 that overlaps with it.

[0077] In this embodiment, as an example of the locking unit 150, at the overlapping parts of the upper and lower frames 111a and 111b of the first front frame 111 and the upper and lower frames 112a and 112b of the second front frame 112, a plurality of fixing holes (not shown) are respectively formed to move along the length direction.

[0078] In this regard, according to the spacing G at the fish passage exit 10, with the upper and lower frames 112a, 112b of the second front frame 112 as a reference, move the upper and lower frames 111a, 111b of the first front frame 111. After adjusting the integrated length, overlap one or more of the upper and lower frames 111a, 111b of the first front frame 111 and the upper and lower frames 112a, 112a of the second front frame 112, and form a fixed fixing class 151 on multiple fixed parts of the upper and lower frames 112a, 112a, 112b of the second front frame 112. By restricting the relative movement between the front frames 111, 112, the first and second front frames 111, 112 can be fixed. When disassembling, remove the fixing screw 151, and then completely remove the upper and lower frames 111a, 111b of the first front frame 111 from the upper and lower frames 112a, 112b of the second front frame 112, so as to realize the relative movement between the first front frame 111 and the second frame 112. They can be separated from each other.

[0079] In addition, as Figure 6 shown, on the outside of the vertical frame of any one of the front frames, for example, the vertical frame 112c of the second front frame 112, the vertical frame 112c and the side-by-side adjustment frame 112d can be equipped. A fine adjustment unit 160 is equipped between the vertical frame 112c and the adjustment frame 112d, and the spacing between the vertical frame 112c and the adjustment frame 112d can be finely adjusted.

[0080] At this time, the fine adjustment unit 160 can be configured between the vertical frame 112c and the adjustment frame 112d, and can be unfolded or folded into multiple frames in a Java manner with respect to each other.

[0081] That is to say, the upper and lower ends of both sides of the multiple frames are alternately located on the vertical frame 112c and the adjustment frame 112d, and can be unfolded or folded with respect to each other based on the rotation axis overlapping in the center, and the spacing between the vertical frame 112c and the adjustment frame 112d can be finely adjusted.

[0082] Therefore, for the fish collection device 100 for fishway investigation in this embodiment, corresponding to the spacing at the fishway exit 10, after adjusting the integrated length between the first and second front frames 111, 112, by finely adjusting the spacing between the vertical frame 112c and the adjustment frame 112d, the spacing at the fishway exit 10 can be more accurately fitted for installation.

[0083] In addition, if further referring to Figure 7, in this embodiment, the fish collection device 100 for fishway investigation may include a guiding net 170 disposed in the vertical frame 122c of the second side frame, which is the vertical frame of the side frame having the collection barrel feet 130, for adjusting the deployment area of the guiding net 140 by expanding or winding the guiding net 140 according to the integrated lengths of the first and second front frames 111 and 112.

[0084] At this time, the guiding net adjustment unit 170 may include a rotating roller 171 around which the end of the guiding net 140 can be wound, a gear 172 whose end of the rotating shaft of the rotating roller 171 can rotate together with the rotating roller 171, and a rotating handle 173 and a rotation restricting or fixing member 174 of the gear 172 provided for restricting or releasing the rotation operation of the gear 172.

[0085] At this time, the rotating roller 171 may be located inside the vertical frame 122c of the second side frame 122, and the rotating roller 171 itself may also replace the vertical frame 122c.

[0086] Moreover, one end of the rotating shaft of the rotating roller 171 protrudes outside the upper frame 122a of the second side frame 122, and the striking of the rotating shaft of the rotating roller 171 can rotate on the lower frame 122b of the second side frame 122.

[0087] In this regard, the gear 172 may be connected to one end of the rotating shaft of the rotating roller 171 from the outside of the upper frame 122a of the second side frame 122, and rotate the rotating roller 171 forward and backward together with the gear 172 according to the forward and reverse rotation of the rotating handle 173, so as to expand or wind the guiding net 140.

[0088] At this time, the fixing member 174 may be in the form of a latch that can rotate on the side of the gear 172 outside the upper frame 122a of the second side frame 122. Therefore, a section of the fixing member 174 may be caught or released by the gear 172, so as to maintain the deployed state of the guiding net 140, or the guiding net 140 can be converted to the rotating state of the traction net 171.

[0089] In addition, the length formed by the second side frame 122, which is the side frame connected to the collection cylinder 130, is greater than that of the other side frame, i.e., the first side frame 121. The guiding net 140 between the second side frame 122 and the first side frame 121 may be in the form of a wall facing the fish inlet 130a.

[0090] Therefore, the fish attracted into the attracting space S1 can be naturally guided to the side of the fish inlet 130a by the attracting net 140, so that the fish in the collecting bucket 130 can be collected more easily.

[0091] Among them, the collecting bucket 130 may include a first collecting bucket 131 connected to the fish inlet 130a and into which the fish flowing in through the fish inlet 130a are first collected, and a second collecting bucket 132 that is connected to the first collecting bucket 131 but can be temporarily opened for connection. After the fish collected in the first collecting bucket 131 flow in, the second collecting bucket 132 finally becomes the container for the fish.

[0092] At this time, the striking part of the second collecting cylinder 132 can be completed with a structure tied with a knot.

[0093] In this regard, when the span portion of the second collecting bucket leg 132 is tied, by only lifting the second collecting bucket leg 132, the simply collected fish can be confirmed, and the fish easily collected by untying the knot of the span portion of the second collecting bucket leg 132 can be collected and investigated without disassembling or removing the fish collecting device 100.

[0094] In addition, although not described in detail, an automatic monitoring device can also be installed to detect the fish entering the collecting bucket 130 through the fish inlet 130a, making it possible to detect the inflow of fish and count the number of individuals.

[0095] Some representative embodiments of the present invention have been described in detail above. However, those with ordinary knowledge in the technical field to which the present invention pertains will understand that the embodiments can be variously modified without exceeding the scope of the present invention.
