Abstract

The utility model relates to a rotating self-oriented fishing cage, belonging to a fishing cage. The utility model is characterized in that the rotating self-oriented fishing cage is provided with upper and lower to net hoops. An upright post is installed between the upper and the lower net hoops. The central positions of the upper and the lower net hoops are respectively provided with an upper shaft sleeve and a lower shaft sleeve. A penetrating central shaft is penetrated in the upper and the lower shaft sleeves. The lower end of the central shaft is connected with a base. The side walls of the rotating self-oriented fishing cage are provided with a fish inlet port on a down stream end, and the inner part of the fish inlet is concave inward. The side walls of the rotating self-oriented fishing cage are respectively provided an inverted beard mouth, and the back part of the inverted beard mouths are connected with inverted beard. Both side of a fish inlet port inside the rotating self-oriented fishing cage are respectively provided with a stream sheet plate. The rotating self-oriented fishing cage has simple structure, low cost, large fishing amount. The direction of the fish inlet port is always in consistent with the direction of water stream, so the effect on catching fish in down stream is good.

Description

Rotation is from directed fishpot

The utility model relates to a kind of fishpot, particularly rotatable fishpot.

At present, people are in the river, when river, lake, reservoir fishing, generally all use traditional fishing net, promptly adopt sticking net, trawlnet, because above-mentioned waters Zhong Keng, ditch are many, be subjected to the mud in the waters, the influence of stone riprap or pot barrier such as shape and complex-terrain uses traditional fishing's netting gear to be difficult to a large amount of upper, middle and lower layer fish that catch, and gets a fright owing to leak the fish that catches, easy damaged, influence the normal growth of upper, middle and lower layer fish, influenced fish crop, and adopted traditional fishing's netting gear, labour intensity is big, needs the operation of tens people ability; Because the waters water (flow) direction constantly changes, netting gear can't adapt to, so be difficult to catch fish downstream.

The purpose of this utility model be a kind of influence that is not subjected to any complex water areas will be provided, can Sui the time and the rotation that is consistent of water (flow) direction from directed fishpot.

The purpose of this utility model is to realize like this, this fishpot has upper and lower two net circles, between upper and lower net circle column is installed, the home position of upper and lower net circle has upper and lower axle sleeve, is installed with a central shaft that runs through in the upper and lower axle sleeve, the central shaft lower end is connected with base, on the sidewall of fishpot, have and hold fish inlet downstream, hold the fish inlet indent downstream, the palpus mouth is arranged down on the sidewall of fishpot, fall must mouthful after be connected with down palpus, in cage, respectively there is a flow plate fish inlet both sides.

In the such scheme, because this fishpot is a cylinder, there is axle sleeve in the center of circle at cylinder two ends, is installed with central shaft in the axle sleeve, so, can rotate freely; Because the flow plate is installed in cage, thus this fishpot can Sui the time according to the direction of current, adjust the direction of fishpot fish inlet and current, itself and water (flow) direction are consistent, reach the purpose of this utility model.This fishpot is simple in structure, and cost is low, and is easy to use, and fishing is many, and remarkable in economical benefits does not influence the normal growth of fish, and its fish inlet direction always keeps consistent with water (flow) direction, and fish is effective downstream so catch, and is not subjected to waters, the restriction of water surface size.

Be described further in conjunction with the embodiments with reference to the accompanying drawings below.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Embodiment: between the online circle 1 of fishpot and the off line circle 7 column 8 is installed, on the three-dimensional shape that this fishpot forms, is sewed with the net sheet.In online circle 1 and following circle 7 circles that surround, the supporting of one " greatly " font is arranged respectively, the home position that in " greatly " font supporting junction, center is upper and lower net circle has upper and lower axle sleeve 2, be installed with a central shaft that runs through 6 in the upper and lower axle sleeve 2, central shaft 6 lower ends are connected with base 5, and base is " ten " font.On the net sidewall of " greatly " font bottom female parts, have and hold fish inlet downstream, have one fall must mouthfuls 4 in the fish inlet of the end downstream lower end of indent, respectively having one on the net sidewall of, upper end left and right at " greatly " font, fall must mouthfuls 4, all fall all to be connected with one after must mouthfuls 4, and fall must 9, in cage, hold the fish inlet both sides that one flow plate 3 is respectively arranged downstream, flow plate 3 is vertically mounted between the upper and lower net circle.

Claims

1, a kind of rotation is characterized in that from directed fishpot: this fishpot has upper and lower two net circles, between upper and lower net circle column is installed.The home position of upper and lower net circle has upper and lower axle sleeve, be installed with a central shaft that runs through in the upper and lower axle sleeve, the central shaft lower end is connected with base, on the sidewall of fishpot, have and hold fish inlet downstream, hold the fish inlet indent downstream, on the sidewall of fishpot, have down must mouthful, fall must mouthful after be connected with down palpus, in cage, respectively there is a flow plate fish inlet both sides.

2, rotation according to claim 1 is from directed fishpot, it is characterized in that: in described online circle and the circle that following corral becomes the supporting of one " greatly " font is arranged respectively, supporting the junction, center at " greatly " font is that the home position of upper and lower net circle has upper and lower axle sleeve.

3, rotation according to claim 1 is characterized in that from directed fishpot: describedly fall must mouth to be arranged on that " greatly " font is left and right, on the net sidewall of upper end.
