Field of Invention
The present invention relates a fishing device, and more particularly to fishing device for silver carp (Hypophthalmichthys molitrix).
Description of Related Arts
Conventional fishing methods which are commonly used for silver carp fishing includes fishhooks fishing, fishing by small fishing nets and seine fishing using a seine or dragnet. However, in waters with relatively high density of silver carp, the use of fishhooks and small fishing nets for fishing has the drawbacks of low fish catch and large manpower requirement, which is not suitable for large scale fishing. When seine fishing is used, the fish being caught may escape into the water easily and classification fishing for silver carp cannot be achieved. Hence, the fishing efficiency is affected. In short, the work efficiency is low and the manpower is wasted.
In order to solve the problems of silver carp fishing in waters with relatively high density of silver carp in common fishing methods, which are: low fish catch and large manpower requirement which is not suitable for large scale fishing in fishing with fishhooks and small fishing nets, and failure to provide classification fishing for silver carp which in turn resulted in low fishing efficiency, low work efficiency and wasting of manpower in seine fishing, an object of the present invention is to provide a fishing device for silver carp which can resolve the above problems.
Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.
According to the present invention, the foregoing and other objects and advantages are attained by the followings:
A fishing device, which includes a tow boat, a noise generator, a Catamaran boat plate, a collection net assembly, a Catamaran, two rigid tow bars and a plurality of bent tubes. The collection net assembly includes an inlet net frame, a collection net, a rectangular outlet door and two blocking nets. The Catamaran boat plate is a bent plate. The blocking net comprises a triangular net frame and a net unit fittingly provided on the net frame. The inlet net frame comprises a cylindrical body defining two end openings at two ends and an inlet net unit surrounding the cylindrical body. The collection net comprises a cylindrical body defining two end openings at two ends and a collection net unit surrounding the cylindrical body. The right end of the inlet net frame is connected through the left end of the collection net. The rectangular outlet door is mounted to the right end of the collection net. The bottom of the rectangular outlet door is hinged to arrange on the bottom end opening on the right end of the collection net. The top of the rectangular outlet door is arranged on an open end of the rectangular frame of the collection net. A net unit for the rectangular outlet door is fittingly provided for the rectangular outlet door. The two blocking nets are vertically and fixedly mounted on the left end of the inlet net frame. The Catamaran boat plate is fixedly mounted on the Catamaran. The Catamaran boat plate has a front portion upwardly projected perpendicularly along a forward direction of the ship body of the Catamaran. The bent plate of the Catamaran boat plate has a front end fixedly mounted on the bow of the Catamaran and a rear end fixedly mounted on the stern of the Catamaran. The plurality of bent tubes is arranged in parallel and are fixedly mounted on top of the top side of the Catamaran. The two blocking nets, the inlet net frame and the collection net are mounted on the plurality of bent tubes sequentially from left to right direction. The left side of the bow of the Catamaran is connected to the tow boat. The stern of the tow boat is hinged with the two rigid tow bars respectively. The two rigid tow bars are connected to the two hulls of the Catamaran respectively. The noise generator is fixedly mounted on the tow boat.
The advantageous effects according to the present invention are:
(a) the present invention is targeted on fishing in waters with relatively high density of silver carp. Through the tow boat 1 and the noise generator 6, a great noise level is generated. When the tow boat is moving, the silver carps will be frightened and swimming around the water surface. When the fish jumps out of the water or swims around the water surface, through the plurality of bent tubes 10 in the bow of the Catamaran 4, the fish is guided through the bent tubes 10 to slide inside the collection net assembly 3. Thus a large number of fishes is collected and the fishing efficiency is greatly increased.
(b) the collection net assembly 3 includes two mounting brackets 15. When the fish catch quantities in the collection net assembly 3 is relatively high, a crane can be used to hook onto the mounting brackets 15 to move the collection net assembly 3 to the fish loading zone. Then, the rectangular outlet door 11 is open and the fish is loaded to a designated zone, which greatly increase the fishing efficiency while a high survival rate of fish catch can be ensured.
(c) the present invention does not require the use of mesh or screen or its maintenance. Thus the cost is saved while the work efficiency of silver carp fishing is increased.
(d) the present invention can save a lot of manpower and lower the labor requirement.
(e) the present invention is simple in structure, convenience in operation and has high efficiency. In addition, no damages to the fish catch is caused by the present invention such that the survival of fish catch can be ensured and the resources utility rate is increased.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

Work Principle
The operation of the fishing device for silver carp according to the present invention is illustrated is follows: The fishing device is dragged into the water. The bent tubes 10 at the front end of the Catamaran 4 is extended to below the water surface. When fishing, start the tow boat 1 and the Catamaran 4 respectively. Drive the tow boat 1 and the Catamaran 4 at the same speed and at the same time turn on the noise generator 6 on the tow boat 1. When the tow boat 1 and the noise generator 6 generates noise to the fish around the tow boat 1, the fish around the tow boat 1 will tend to swim in the water surface or jumping out of the water. After the tow boat 1 moves forward, the net opening of the collection net assembly 3 on the Catamaran 4 moving behind the tow boat 1 will be in a corresponding position to collect the fish around the water surface or the fish jumping out of the water. When the fishes are collected, the two mounting brackets 15 are hooked and lifted by a crane and the collection net assembly 3 is moved to a fish loading zone. Then the rectangular outlet door 11 of the collection net assembly 3 is open and the fish catch is loaded. After loading the fish catch, the collection net assembly 3 is moved back to the Catamaran boat plate 2 and the two positioning shafts 13 are positioned on the two U-shaped hooks 12. Then, the fishing device can be used for fishing again repeatedly and the object of the present invention is achieved.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
