Abstract
The invention relates to a fishing tackle, in particular to a vertical curved cutwater board, which comprises a baffle board, an upper scupper board, a lower scupper board, a connection board and a netting gear connection board. The cutwater board is characterized in that the baffle board is arc-shaped, the straight edge of the baffle board is connected with the connection board through a U-shaped connection piece and the arc edge of the baffle board is connected with the arc shaped upper and lower scupper boards. The surface area of the lower baffle board is larger than that of the upper baffle board. The included angle between the baffle board and the upper and the lower scupper boards is larger than 90 DEG. The cutwater board is designed from a viewpoint of hydrodynamics, which changes the surface structure and shape of the cutwater board, increases the water flow impulsive force of the cutwater board and fully achieves the horizontal expansion of the netting gear and the multi-layer fishing. The cutwater board has the advantages of high expansion capacity, great stability without tending to side turning, easy operation, long service life, good application effect and, etc.
Description
Technical field:
The present invention relates to fishing device, specifically a kind of vertical type curved face water diversion plate.
Background technology:
As everyone knows, trawlnet is the widest instrument of fishing for that uses in the marine fishing, traditional trawlnet divides two trawlnet tools and otter-trawl tool, two trawlnet tools are two manropes that pulled trawlnet by two towboats respectively, two trawlnet mouths are opened fishes for, its deficiency be must two towboats operation simultaneously, energy utilization rate low etc., branch water plate is the vitals in the otter-trawl operation process, its effect is by seawater and the impulsive force that divides the formation of water plate surface, network interface is effectively opened, amass thereby improve the sea of sweeping of dredging the order otter-trawl, increase fishery output.
Present branch water plate is to be respectively equipped with water fender and following water fender on the straight plate shape of homalographic in rectangular dividing plate both sides, dividing plate is connected with connecting plate through the U-shaped connector, connecting plate is provided with the hole that is connected with fishing boat, last water fender and the following water fender back side outside is respectively equipped with the netting gear connecting plate of the usefulness that is connected with fishing net, the netting gear connecting plate is provided with connecting hole, this minute water plate can only be applicable to that (size of mesh is 100-1 to little mesh, 000 millimeter) otter-trawl, and can only be adapted to the bottom trawling, application surface is narrower; Specifications and models are single; Profile mainly contains ellipse and rectangle, and surface structure design is comparatively simple; The impulsive force that is produced is less relatively; Various for model, as to need complex job thin order (size of mesh is 1,000-30,000 millimeter) otter-trawl exists significant limitation in the use, and these limitation have directly influenced the fishing efficiency of thin order otter-trawl and applied.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, improve existing design, change the surface texture that divides the water plate, strengthen the impulsive force that divides the water plate, provide that a kind of expanding ability is big, the vertical type curved face water diversion plate of good stability from the angle of hydrodynamics.
The present invention can reach by following measure:
A kind of vertical type curved face water diversion plate, comprise dividing plate, water fender, connecting plate and netting gear connecting plate, it is characterized in that dividing plate is circular arc, the straight flange of dividing plate is connected with connecting plate through the U-shaped connector, the arc limit of dividing plate is connected with following water fender with curved last water fender, the surface area of following water fender is greater than the surface area of last water fender, and the angle between dividing plate and last water fender, following water fender is greater than 90 °.
The present invention can be provided with reinforcement in the middle part of last water fender and following water fender, and reinforcement is provided with hoisting ring, to increase intensity of the present invention, improves impact resistance, makes things convenient for the loading and unloading of mechanization of the present invention.
The present invention can be provided with Weight plate on perform water plate and following water fender, generally be located at down the downside of water fender, carries out work to regulate the present invention at different water layers, enlarges the scope of application of the present invention.
The present invention can also be respectively equipped with the adjusting support on water fender and the connecting plate down, and two regulate support is connected through drag-line, with the angle between control connection plate and following water fender, makes the present invention be in good working order all the time.
The present invention can the Xia Fenshui plate and on divide the dual-side of water plate to be respectively equipped with fin, fin forms water stream channel, makes the water (flow) direction of the passage of flowing through reach side flow backward, to increase side force, dredges the open needs of order traw mouth to adapt to.
The present invention changes the surface texture and the shape of dividing the water plate from the angle design of hydrodynamics, strengthens the impulsive force that divides the water plate, realizes the horizontal expansion of netting gear, also can become the water layer operation, and it is big to have expanding ability; Be difficult for rollover, good stability; Advantages such as simple to operate and long service life, result of use are good.
