One washes net dish under water
Technical field
The present invention relates to the net washing device for fish culture net cage, be specifically related to one and wash net dish under water.
Background technology
In recent years, due to the destruction of the marine eco-environment and the pollution of cage culture self, make net cage very easily accompanying by some fouling organisms, not only cause the shortening in etting life-span, and bring great negative effect to management, cultivation.Make water exchange capacity inside and outside net cage reduce on the one hand, breeding environment is deteriorated, and have impact on growth rate and the survival rate of cultivation fish body, and easily brings out disease; On the other hand, etting resistance increases considerably, and exacerbates the drift of etting under action of ocean current, and while causing cultivation volume significantly to reduce, the friction between etting also can cause the mechanical damage of cultivation object.Therefore, need to remove any fouling organism be attached on net cage in time.
At present, solution to the problems described above is the cleaning operation carrying out aufwuch when artificial replacing etting, but the etting being covered with fouling organism brings very large difficulty to draping operation, not only needs to drop into more manpower, and draping process also has scratch to a certain degree to cultivation fish body.Such as: the etting that girth is 40m, high 6m, lateral area are about 200m2 was placed in seawater after three months, and the etting gross weight after aufwuch can reach 1 ton.When manually changing etting and cleaning operation under existence conditions, there is following shortcoming: labour intensity is large, the operating time is long, Personal Safety is poor, and abraded largely because net cage draping overlong time causes cultivation fish to be known from experience.
Summary of the invention

Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1 to Figure 3, the present invention washes net dish under water and comprises circular outer bearer bar 14, and the top of described circular outer bearer bar 14 is fixed with some annular grids 6 by radial after-poppet 5; Particularly; radial after-poppet 5 is L-shaped; a support arm of this L shape after-poppet 5 is by the inwall riveted of screw and circular outer bearer bar 14; another support arm of this L shape after-poppet 5 radially extends to the top center of circular outer bearer bar 14, and is fixedly connected with the flange 4 being located at circular outer bearer bar 14 top center.
Described flange 4 is connected with neatly ring 1, and neatly ring 1 inside is provided with axial central through hole 2; Neatly ring 1 side is provided with the radial high-pressure conduit axle 3 be communicated with axial central through hole 2, and described high-pressure conduit axle 3 center is provided with water stream channel; In order to connect the delivery port of high-pressure pump.
The bottom of described neatly ring 1 is provided with Connection Block 7, and described Connection Block 7 can rotate around described neatly ring 1; Described Connection Block 7 is connected with some radially-arranged manifolds 10; Described manifold 10 communicates with the axial central through hole 2 of neatly ring 1, as a part for water stream channel; The end of described manifold 10 is provided with nozzle Connection Block 11, and nozzle Connection Block 11 is provided with the high pressure nozzle 12 be communicated with manifold 10, as the jet of water under high pressure; The plane that high pressure nozzle 12 and each manifold 10 form has certain angle.
The back side of described manifold 10 is also provided with radial direction and turns up blade 9, and the blade 9 that turns up is fixed on Connection Block 7 by connecting rod 8.Preferably, the length of blade 9 of turning up is consistent with the length of manifold 10.Turn up blade 9 in order to produce certain thrust to offset the reaction force of high pressure nozzle 12.
Workflow of the present invention is as follows: the delivery port of high-pressure water pipe is connected on high-pressure conduit axle 3, the water stream channel of water under high pressure through high-pressure conduit axle 3 center that high-pressure hydraulic pump produces enters to the axial central through hole 2 of neatly ring 1 inside, thus flow to manifold 10, the oblique ejection of final arrival high pressure nozzle 12, produce cavity jet, the reaction force acts of cavity jet, in manifold 10, causes the High Rotation Speed of manifold 10, thus expands cleaning area; The High Rotation Speed of manifold 10 drives the radial direction at its back side to turn up blade 9 High Rotation Speed, the radial direction blade 9 that turns up produces reverse flow thrust when rotated, cause in etting cleaning process, manifold 10, high pressure nozzle 12 are attached to etting surface, keep in touch state always.
The outer wall of described circular outer bearer bar 14 is provided with link such as draw-gear such as suspension ring 17 grade.In use, draw-gear link is installed traction element such as pull rope/bar, utilize traction element the present invention to be washed after water put into by net dish and lift, in the process of lift, the present invention washes the work of net dish and cleans etting.
As improvement, bottom described Connection Block 7, connect a front apron 15 by a self-lubricating back shaft 13, for the rotation of manifold 10, the blade 9 that turns up provides axial holding power.The gap sprayed for water under high pressure is left between described front apron 15 and circular outer bearer bar 14.
The present invention realizes the cleaning to etting by some manifolds and blade rotation, compared with the mode of operation of rotating with traditional whole high-pressure chamber, significantly reduces construction weight, adds the simplicity manufacturing and install, component module, be more convenient for part exchanging and maintenance.In addition, the blade that turns up is arranged along manifold radial direction, larger water suction area can be produced, enough large thrust can be produced under lower rotating speed during blade rotation of turning up, can reduce the pressure loss like this, improve cleansing power, reduce energy dissipation, the running of the slow-speed of revolution simultaneously can improve life-span, the raising safety in utilization of rotatable parts.
Above-described embodiment, just in order to technical conceive of the present invention and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The change of every equivalence done by the essence of content of the present invention or modification, all should be encompassed in protection scope of the present invention.
