Abstract
A diving device used in a sampling mesh relates to a diving device for a marine life sampling mesh, and aims to solve the technical problems through providing a diving device for a mesopelagic sampling mesh. The utility model adopts the technical scheme that a framework, a steel plate and drag plates are included, and is characterized in that the framework of the diving device adopts stainless steel tubes with a diameter of 25mm through welding, and the tube wall thickness is 1mm; the stainless steel plate is welded on the impacted face of the framework to serve as a flow guiding plate; the flow guiding plate is formed by two wing-shaped plates arched in the middle, the included angle between the two wing-shaped plates is 150 degrees; the two wing-shaped plates and the horizontal plane form an attack angle of 20 degrees; and two triangular drag plates are hinged at two ends of each wing-shaped plate. The utility model is suitable for the marine life sampling mesh.
Description
Technical field
The utility model relates to the following submersible device that sea life sampling net is used.
Technical background
At present, when marine fishery resources was investigated, employing sampling net was taked the biological sample in the ocean.The general mode that increases gravity (sinker) that adopts of sampling net is sunk netting gear.But the mode that increases gravity can make the weight of whole top netting gear rise.Also can have to increase greatly heavy power because the sinking acting force is little or unclasp the longer guiding principle length of draging in the local operation of the anxious depth of water of stream.Waste activity duration and increase operation easier.
The utility model content
The utility model technical issues that need to address provide a kind of dive device with Yu Haiyang middle level sampling net.
The technical solution of the utility model is made up of framework, steel plate, towing plate, the framework that it is characterized in that the dive device adopts diameter 25mm stainless-steel tube to be welded, pipe thickness 1mm, at framework fluoran stream surface soldering stainless steel plate as fair water fin, the airfoil plate that fair water fin is arched upward by 2 centres is formed, angle between the both wings is 150 degree, and forms the 20 degree angles of attack with surface level, two blocks of leg-of-mutton towing plates of airfoil plate two ends hinge.
Characteristics of the present utility model are in light weight, dive is stable, can stall, and can play compared with traditional sinker and to shorten the effect of draging guiding principle, particularly in the place that The water is deep and the current fast netting gear being sunk to needs the degree of depth of operation, and the change of towing speed, flow velocity is less to the influence of its depth of implements.
Description of drawings
What Fig. 1 represented is the structural representation of dive device.
What Fig. 2 represented is the framework synoptic diagram of dive device.
Embodiment
The utility model is taked the span total length of both wings and the equal in length of the lower end of sampling net.The framework 3 (Fig. 1) of dive device adopts diameter 25mm stainless-steel tube to be welded, and more than the pipe thickness 1mm, its effect is a bracing means, makes it reach intensity, and supports that fair water fin forms required angle (see figure 2).As fair water fin 1 (Fig. 1), current and fair water fin face form certain angle of attack at framework fluoran stream surface 21 (Fig. 2) soldering stainless steel plate, potentiality under producing under the effect of current.Fair water fin is made up of 2 blocks of intermediate projections airfoil plates, and the angle between the both wings is 150 degree, and forms the 20 degree angles of attack (upper counterangle) with surface level.The length breadth ratio of every block of airfoil plate is 6, and the fluoran stream surface bending curvature of airfoil plate is 15%, adopts hinge type to connect equilateral triangle towing plate 2 (Fig. 1) at the two ends of both wings, and the towing plate thickness is 4 millimeters, and the centre is a lightening hole.Towing plate base equates that with the wide of airfoil fair water fin the towing hole 4 (Fig. 1) of 12 millimeters of three diameters is made a call on towing plate top, so that the coupling yoke guiding principle and the adjustment angle of attack produce the dive acting force under the angle of attack of design.
Claims (2)
1. dive device of net that is used to take a sample, form by framework, steel plate, towing plate, the framework that it is characterized in that the dive device adopts diameter 25mm stainless-steel tube to be welded, pipe thickness 1mm, as fair water fin, the airfoil plate that fair water fin is arched upward by 2 centres is formed at framework fluoran stream surface soldering stainless steel plate, and the angle between the both wings is 150 degree, and form the 20 degree angles of attack with surface level, the airfoil plate two ends two blocks of leg-of-mutton towing plates that are hinged.
2. the dive device of a kind of net that is used to take a sample according to claim 1, the length breadth ratio that it is characterized in that every block of airfoil plate is 6, the fluoran stream surface bending curvature of airfoil plate is 15%.
