Description

Technical Field

[0001] This invention relates to a float, and more specifically to a float that is better adapted to use in water flow environments. Background Technology

[0002] A spherical float is a common type of hollow float. It is widely used in trawls, fixed set nets, and fixed gillnets. In trawls, its function is to maintain the vertical extension of the net opening together with the sinker (bottom line, sinker line, etc.). In set nets, one type has the float attached to the netting at the opening, serving the same function as a trawl float; another type has the float connected to the gillnet by a rope, floating on the surface and marking the position of the gillnet in the water (facilitating hauling in and out of the net, and retrieving the catch). In gillnets, it prevents the net from collapsing to the seabed under the impact of ocean currents, thus affecting the fishing results. In addition, it can be used as other buoys as needed, such as for positioning set net stakes (or anchors).

[0003] The drawback of spherical floats (including other cylindrical floats) is that when impacted by water flow, the lower half facing the current (about 1 / 4 of the spherical surface) is below the water surface and generates upward buoyancy, while the upper half facing the current is above the water surface and is impacted by the water flow, generating downward pressure. This causes the buoyancy of the spherical float to be partially or even completely canceled out, affecting its performance in flowing water environments. Summary of the Invention

[0004] The purpose of this invention is to provide a float that can utilize the impact of water flow to increase the upward force of the float, making it better suited for use in water flow environments and effectively solving the problem of water flow impact offsetting the buoyancy of the float.

[0005] The technical solution of this invention is:

[0006] A float includes a lower float and an upper float, wherein the upper float is a conical float with an outer diameter that gradually increases from bottom to top, and a plurality of lifting plates are provided on the outer side of the upper float, which are arranged sequentially from bottom to top. Each lifting plate has one or more lifting holes that penetrate the upper and lower surfaces of the lifting plate, and the cross-sectional area of ​​the lifting holes gradually decreases from bottom to top. In actual use, the lower part of the float in this design is underwater, while the upper part is above the water surface. When the upper part, facing the current, is impacted by the water flow, the water flows upward along the outer side of the conical float. Upon encountering the lifting plates, the upward-flowing water flows upward along the lifting holes (the horizontally flowing water enters from the spaces between the lifting plates and flows upward along the outer side of the conical float after encountering it). According to the principles of fluid mechanics, the water flowing from the large inlet and the small outlet generates a vertically upward lift (equivalent to buoyancy). This utilizes the impact of the water flow to increase the upward lift of the float, enabling it to better adapt to use in flowing water environments. This effectively solves the problem of water flow impact offsetting the buoyancy of the float and affecting its performance in flowing water environments.

[0007] Preferably, the lifting plate is annular and coaxially distributed with the upper float. Several lifting holes are provided on the same lifting plate, and these holes are evenly distributed around the circumference of the lifting plate. In this way, when the float is impacted by water flow from all directions, it can generate vertically upward lift (equivalent to buoyancy). This utilizes the impact of water flow to increase the upward lift of the float, making it better suited for use in flowing water environments. This effectively solves the problem of water flow impact offsetting the buoyancy of the float and affecting its performance in flowing water.

[0008] Preferably, the lifting plates are distributed in several layers from bottom to top. Each layer consists of several lifting plates evenly distributed around the upper float, and each lifting plate has a lifting hole. In this way, when the float is impacted by water flow from all directions, it can generate vertical upward lift (equivalent to buoyancy). This utilizes the impact of water flow to increase the upward lift of the float, making it better suited for use in flowing water environments. This effectively solves the problem of water flow impact offsetting the buoyancy of the float and affecting its performance in flowing water environments.

[0009] Preferably, in the circumferential direction of the upper floating body, the lifting plates in any two adjacent layers of lifting plates are staggered.

[0010] Preferably, both the lower and upper floats are hollow structures, and the lower and upper floats are manufactured separately, but are connected as one unit.

[0011] Preferably, the upper float and the lifting plate are integrally molded.

[0012] Preferably, the upper float and the lifting plate are manufactured separately, with the lifting plate fixed to the outer surface of the upper float.

[0013] Preferably, the lifting plates extend radially along the upper float, and the length of each lifting plate extending radially along the upper float increases and then decreases from bottom to top.

[0014] Preferably, the lower float is hemispherical.

[0015] Preferably, the bottom outer side of the lower float is provided with a connector, and the connector has a rope hole. In this way, when the float is used on trawl nets, fixed gillnets, fixed barbed wire, and other netting, the float can be installed on the net by passing a connecting rope through the rope hole.

[0016] The beneficial effects of this invention are:

[0017] In actual use, the lower float is underwater and the upper float is above the water surface. When the upper float facing the current is impacted by the water flow, the water will flow upward along the outer side of the conical float. After encountering the lifting plate, the upward-flowing water will flow upward along the lifting hole. According to the principles of fluid mechanics, the water flowing from the large opening to the small opening will generate a vertical upward lift (equivalent to buoyancy). Thus, the impact of the water flow is used to increase the upward lift of the float, making it better adaptable to use in water flow environments. This effectively solves the problem of the water flow impact offsetting the buoyancy of the float and affecting the performance of the float in water flow environments. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a float includes a lower float 1 and an upper float 2, wherein the upper float 2 is a conical float with an outer diameter that gradually increases from bottom to top. Several lifting plates 3 are arranged sequentially from bottom to top on the outer surface of the upper float 2. Each lifting plate has one or more lifting holes 4. The lifting holes penetrate the upper and lower surfaces of the lifting plates, and the cross-sectional area of ​​the lifting holes gradually decreases from bottom to top.

[0030] In actual use, the lower float of this embodiment is underwater, and the upper float is above the water surface. When the upper float facing the current is impacted by the water flow, the water will flow upward along the outer side of the conical float (the horizontally flowing water flows in from the space between the lifting plates, and after encountering the conical float, the water will flow upward along the outer side of the conical float). The upward flowing water will flow upward along the lifting holes after encountering the lifting plates. According to the principles of fluid mechanics, the water flowing from the large opening to the small opening will generate a vertically upward lift (equivalent to buoyancy). Thus, the water flow impact is used to increase the upward lift of the float, making it better adaptable to use in a water flow environment. This effectively solves the problem that the water flow impact cancels out the buoyancy of the float, affecting the float's performance in a water flow environment.

[0031] In this embodiment, the center of gravity of the float is distributed on the lower floating body, so that when the float is floating on the water surface, the lower floating body is in the water and the upper floating body is above the water surface.

[0032] In this embodiment, the tilt angle of the conical float is 30-60 degrees, for example, the tilt angle of the conical float is 30 degrees, 45 degrees, or 60 degrees.

[0033] In one embodiment of this invention, both the lower and upper floats are hollow structures, and the lower and upper floats are manufactured separately, but are also connected as one unit.

[0034] In another embodiment of this invention, the upper float and the lifting plate are integrally formed. Both the lower float and the upper float are hollow structures.

[0035] The upper float and the lifting plate are manufactured separately. The lifting plate is fixed to the outer surface of the upper float, for example, by welding or bonding. Of course, the upper float and the lifting plate can also be molded as a single piece, for example, by injection molding.

[0036] like Figure 1As shown, the lower floating body is hemispherical. Figure 2 As shown, the lower floating body is cylindrical.

[0037] The lower part of the float has a connector 5 on its outer bottom surface, and the connector has a rope hole. In this way, when the float is used on trawl nets, fixed gillnets, fixed barbed wire, and other nets, the float can be installed on the net by passing a connecting rope through the rope hole.

[0038] The lifting plates extend radially along the upper float. The length of each lifting plate, distributed sequentially from bottom to top, extending radially along the upper float first increases and then decreases.

[0039] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that...

[0040] like Figure 3 As shown, the lifting plate 3 is annular and coaxially distributed with the upper float. Several lifting holes 4 are provided on the same lifting plate, and these holes are evenly distributed around the circumference of the lifting plate. In this way, when the float is impacted by water flow from all directions, it can generate vertically upward lift (equivalent to buoyancy), thereby utilizing the water flow impact to increase the float's upward lift. This allows it to better adapt to use in flowing water environments and effectively solves the problem of water flow impact offsetting the buoyancy of the float, affecting its performance in flowing water environments.

[0041] In this specific embodiment, the remaining structure is the same as in the specific embodiment, except that...

[0042] like Figure 4 As shown, the lifting plates are distributed in several layers from bottom to top. Each layer consists of several lifting plates 3 evenly distributed around the upper float, with each lifting plate having a lifting hole 4. In this way, when the float is impacted by water flow from all directions, it can generate vertically upward lift (equivalent to buoyancy), thereby utilizing the water flow impact to increase the float's upward lift. This allows it to better adapt to use in flowing water environments, effectively solving the problem of water flow impact offsetting the float's buoyancy and affecting its performance in flowing water conditions.

[0043] In one embodiment of this invention, the lifting plates in the upper and lower layers of lifting plates are staggered in any adjacent arrangement along the circumference of the upper floating body.

[0044] In another embodiment of this invention, the lifting plates in any two adjacent layers of lifting plates are arranged facing each other in the circumferential direction of the upper floating body.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
