Problems solved by technology

At the same time, during the rotation process of the diversion turntable, the overall cleaning equipment performs translational or curved motion. Therefore, when the rotation speed of the diversion turntable is too slow, there is no high-speed jet action on the mesh surface in the area where the cleaning equipment passes, resulting in incomplete removal of fouling organisms on the mesh surface. ; When the rotation speed of the diversion turntable is too fast, the fouling organisms on the mesh surface do not reach enough high-pressure jet action time, resulting in poor removal effect of fouling organisms

Embodiment 1

[0050] Such as Figure 1 to Figure 4 As shown, what the present invention discloses is a kind of diversion turntable of deep-water net cage net clothing cleaning equipment, has the turntable body 1 of disc shape; It is characterized in that:

[0051] The circular front 1-1 of the turntable body 1 is provided with n sets of water outlet groups, n≥3, and each of the water outlet groups includes m water outlets 1b arranged at intervals along its extension line 1-1a, m ≥2; the extension lines 1-1a of each group of water outlet groups are evenly spaced around the axis of the turntable body 1, and each of the extension lines 1-1a is the radius of the circular front 1-1 ; The m water outlets 1b of the water outlet groups in each group are respectively located on the m concentric circles 1-1b of different radii of the circular front 1-1;

[0052] The water outlet 1b is a connection port capable of installing a high-pressure nozzle 2 or a plug 3, and the water spray direction of the h...

Embodiment approach

[0062] Each of the water outlet groups is symmetrically provided with m reverse water outlets (not shown in the figure) corresponding to the m water outlets 1b contained therein along its extension line 1-1a.

[0063] Therefore, by choosing to install the high-pressure nozzle 2 on the water outlet 1b or the reverse water outlet, the forward or reverse rotation of the diverting turntable can be controlled.

Embodiment 3

[0065] The present invention also discloses a step-by-step speed adjustment method, which is suitable for the diversion turntable of the deep-water cage net clothes cleaning equipment described in Embodiment 1 or Embodiment 2;

[0066] include:

[0067] Step 1. When cleaning the net clothes of the deep-water net cage, the water inlet 1a of the diversion turntable is rotatably installed to the high-pressure water supply port of the net clothes cleaning equipment of the deep-water net cage through the hollow rotating shaft; One end is fixedly connected with the diversion turntable, and the other end is rotatably matched with the high-pressure water supply port of the deep-water cage net clothes cleaning equipment, and the high-pressure water supply port of the deep-water net cage net clothes cleaning equipment is connected to the diversion turntable through a hollow shaft The water inlet 1a.

[0068] Step 2. Set the target stable rotational speed Ω of the diverter turntable, th...

Abstract

The invention discloses a flow dividing rotary disc for cleaning equipment of net clothing in deep water net cage and a graded rotation speed regulating method thereof. From the first step to the third step, the flow dividing rotary disc can be stably auto-rotated under rotation speed being close to stable rotation speed omega of a predetermined target, the phenomenon that graded rotation speed control of the flow dividing rotary disc can be achieved more accurately under the condition of constant high-pressure water-supply water pressure and no need of additional auxiliary speed regulation mechanism is realized, and thus, appropriate target stable rotation speed omega can be set based on net cage culturing fouling organism attachment types of the net clothing required to be cleaned in the deep water net cage, the best rotation speed of the flow dividing rotary disc is configured when the net clothing is cleaned, and improvement of the cleaning efficiency of the net clothing in the deep water net cage and the removal ratios of the fouling organisms is realized. According to the flow dividing rotary disc disclosed by the invention, the flow dividing rotary disc is stably auto-rotated under rotation speed being close to stable rotation speed omega of the predetermined target while the rotation smoothness of the flow dividing rotary disc can be ensured at the same time, and the cleaning efficiency of the net clothing in the deep water net cage and the removal ratios of the fouling organisms are improved.

Description

technical field [0001] The invention relates to net clothes cleaning equipment for deep-water net cages, in particular to a diverting turntable and a method for adjusting the graded rotation speed of the net clothes cleaning equipment for deep-water net cages. Background technique [0002] Deep-water cage culture is the main way of domestic marine fish culture. The accumulation of fouling organisms in the nets of deep-water cages blocks the mesh, hinders the exchange of water bodies inside and outside the deep-water cages, and in severe cases induces the growth of bacteria, damages water quality, and even causes large-scale death of cultured organisms. At the same time, according to different sea areas and differences in sea area topography, there are great differences in the types, distribution characteristics, and laws of the distribution of net fouling organisms. Shellfish are mainly shellfish. The deep-water cage culture area in Yangjiang, Guangdong is dominated by soil...
