Abstract
A device for catching fish by water flow comprises a working platform. A submerged pump is mounted on the working platform, a water outlet of the submerged pump is connected with a hose, the other end of the hose is connected with a trident pipe after being subjected to gradient diameter-expansion treatment, the other two ends of the trident pipe are connected with a flared water outlet and a fish collecting box respectively, and a porous rectifier is arranged at the joint of the trident pipe and the hose. The device for catching the fish by the water flow has the advantages that the device is designed according to rheotropism of the fish and generates fond flow velocity adapting to physiological living habits of the fish to lure the fish to enter the fish collecting box, so that fish luring and trapping effects are good, and reuse rate is high; the device can be used for the fishing industry and is capable of remarkably reducing fishing strength, energy consumption, improving fishing efficiency and causing no damage to the caught fish, low in requirements on target water area environment conditions and high in stability and safety.
Description
Technical field
The invention belongs to attracting technical field, be specifically related to a kind of device utilizing immersible pump to produce current fish.
Background technology
In rivers,lakes and seas, carry out traditional fishery fish for, mainly taking manually casts net fishes for, and this traditional fishing style also exists a lot of deficiency: 1, labor intensive is too large, and efficiency is low, causes high cost; The netting gear of 2, fishing for easily is damaged by barrier, and recycling rate of waterused is too low, along with the rise netting gear of price is more and more expensive, also causes high cost; 3, for the waters having ecological, environmental protective requirement, easily water area ecological environment is upset; 4, this fishing style easily causes the fish kills of fishing for disembarkation; 5, traditional fishing style is subject to Changes in weather impact, and strong wind and heavy rain weather can not operation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of device utilizing current to fish, easy to operate, has both been applicable to water field of big area fishery and has also been applicable to fish pond and fishes for, and can ensure to fish for the fresh and alive of fish, to improve economic worth; Also can be used as and lure the experimental provision of fish gathering to use.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of device utilizing current to fish, comprise workbench, this workbench is provided with immersible pump, the delivery port of immersible pump is connected with flexible pipe, the other end of flexible pipe is by connecting Y-pipe after the expanding process of gradual change, and the other two ends of described Y-pipe connect horn-like delivery port and fish-collecting box respectively; The junction of described Y-pipe and flexible pipe is provided with porous rectifier.
Described gradual change pipeline is used for modification stability fluidised form, and porous rectifier employing minor-diameter rigid pipe is bonding side by side to be formed.
Described fish-collecting box and Y-pipe junction are provided with rotary switch, escape for preventing catching fish.
Described fish-collecting box has bent passage, and is provided with the flap extended to fish-collecting box inside in passage both sides.Fish-collecting box is used for collecting catches fish, and inner bent passage and flap prevent the fish caught from escaping, and the afterbody of fish-collecting box arranges and can unload case lid, to facilitate the fish taken away and catch.The afterbody of fish-collecting box arranges detachable case lid, to facilitate the fish taken away and catch.
Described immersible pump connects power supply, and control immersible pump by frequency modulator go out water speed.Be adjusted to the hobby flow velocity of fish by the current that immersible pump is produced, carry out induction fishing.Described power supply is used for electric energy and exports, and can adopt distance type mobile direct-current power source or AC power.
Described horn-like delivery port comprises straight length and oared segrne pii, and described oared segrne pii is used for divergent flow, and described oared segrne pii and straight length junction extend to straight length inside, escapes to prevent the fish caught.
The edge of described workbench is provided with multiple hoist cable fixing holes, the immersible pump of this device, flexible pipe, Y-pipe, horn-like delivery port and fish-collecting box are integrated into an entirety by workbench, then can put it into convenient operation under water by rope by rope.
The present invention designs according to the properties of flow that becomes of fish, the hobby flow velocity utilizing device to produce adaptation fish physiological life habit lures that fish enter fish-collecting box into, effectively accomplish that attracting fishing result is good, recycling rate of waterused is high, may be used for fishery to fish for, significantly can alleviate catching intensity, reduce energy consumption, improve catching rate, fish not damaged of catching, and low to target waters requirement for environmental conditions, there is good stability and safety.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is using state schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention includes workbench 1, this workbench is provided with immersible pump 2, the delivery port of immersible pump is connected with flexible pipe 3, the other end of flexible pipe 3 is by connecting Y-pipe 4 after the expanding process of gradual change, and the other two ends of described Y-pipe connect horn-like delivery port 5 and fish-collecting box 6 respectively; Described Y-pipe 4 is provided with porous rectifier 7 with the junction of flexible pipe 3; Described fish-collecting box 6 is provided with rotary switch 8 with Y-pipe 4 junction; Described fish-collecting box 6 has bent passage, and is provided with the flap 9 extended to fish-collecting box inside in passage both sides; Described immersible pump connects power supply 10, and control immersible pump by frequency modulator 11 go out water speed; Described horn-like delivery port comprises straight length and oared segrne pii, and described oared segrne pii and straight length junction extend to straight length inside; The edge of described workbench is provided with multiple hoist cable fixing holes 12.
When using of the present invention, concrete implementation step is as follows:
One, device has been assembled, and made switch 8 be in opening;
Two, frequency modulator 11 is set to fish hobby flow velocity correspondence position, and is connected with hoist cable fixing hole 12 by rope, by device entirety by being steadily positioned over the appropriate depth in target waters;
Three, power-on, immersible pump 2 is started working, and current flow out through immersible pump entrance → submersible pump outlet → flexible pipe → gradual change pipeline section → Y-pipe → horn-like delivery port order;
Four, as shown in Figure 2, wherein solid arrow is water (flow) direction, and dotted arrow is the swimming direction of fish, and because fish have the characteristic of stream, it is by the peripheral waters → horn-like delivery port → Y-pipe → fish-collecting box of device;
