摘要： The invention has a curved board. The curved board is formed into a shape that curves in a curving direction corresponding to an expanding direction of a net opening in a towing state, from a front-side end section that is a front side in a towing direction in the towing state towards a rear-side end section that is a rear side in the towing direction in the towing state. At least one of a projecting structure having a projecting surface, a top board, and a bottom board is formed in the curved board.

摘要： A net-mouth inclined trawl-net apparatus includes a substantially rectangular frame and a trawl net attached to the frame. The trawl net is formed of an upper net, a lower net, and a pair of side nets, and the trawl net has a shape formed of a body part of a quadrangular trapezoid shape. Each of the side nets attached to the frame has a longer side and a shorter side as an upper side and a lower side, and a side of each side net defining a net-mouth edge defines a side-net front edge inclination angle relative to a bottom side of an isosceles trapezoid having the shorter side of the side net as a side of the isosceles trapezoid, so that the frame autonomously maintains an inclination angle relative to the vertical axis due to a flow resistance and a lift acting on the net.
摘要翻译：网嘴斜拖网设备包括大致矩形的框架和连接到框架的拖网。拖网由上网，下网和一对侧网构成，拖网具有由四边形梯形形状的主体部分形成的形状。连接到框架的每个侧网具有较长的侧面和较短的侧面作为上侧和下侧，并且每个侧网的限定网嘴边缘的一侧限定了相对于...的侧网前边缘倾斜角度具有作为等腰梯形侧面的侧网的较短侧的等腰梯形的底侧，由此由于流动阻力和作用在网上的升力，框架自主地保持相对于垂直轴线的倾斜角度。

摘要： There is provided a trawl-net collecting apparatus of net-mouth inclination maintainable type capable of autonomously maintaining a posture thereof. The present invention is a trawl-net collecting apparatus of net-mouth inclination maintainable type in which a trawl net is attached to a substantially rectangular cylindrical frame, the trawl net being formed of an upper net, a lower net, and a pair of side nets, and the trawl net having a shape formed of a body part of a quadrangular trapezoid shape and a cod-end part connected to an end of the quadrangular trapezoidal body part, wherein each of the side nets attached to the frame has a longer side and a shorter side as an upper side and a lower side, and a side defining a net-mouth edge defines a side-net front edge inclination angle (γ), which satisfies a relationship represented by the following expression (1), relative to a bottom side of an isosceles trapezoid having the shorter side as a shorter leg, so that the frame autonomously maintains an inclination angle (β) due to a resistance and a lift of a water flow against the net.
