Problems solved by technology

The filter screen used for collection in aquaculture, due to long-term use, causes underwater bacteria, algae, plants and parasites to adhere to the filter screen, so that the filter screen holes are blocked, thus affecting the normal use of the filter screen
[0003] Cage aquaculture in aquaculture has always been a popular industry. Feces and residual bait produced during moderate aquaculture in flowing water areas will not cause water pollution in aquaculture waters under the action of water flow, but in limited water areas When cage culture is carried out in waters with poor flow and exchange capacity, a large amount of garbage such as feces and unused scattered fish feed is discharged into the water freely. Biological and Aquatic Ecology
The collection device in the prior art generally imports the sewage into the shore, and adopts engineering measures such as sewage treatment methods, so that the investment is large, the cost is high, and there is secondary water pollution.

Embodiment 1

[0041] Embodiment 1 A double-winged grid mechanism 10 for aquaculture

[0042] Such as Figure 1 to Figure 3 As shown, the present embodiment includes a net curtain 1 and a double-winged net fixed on the net curtain 1, and the net curtain 1 and the double-winged net form a soft floating structure with a self-cleaning function. The self-purification referred to here refers to the structure that depends on the fluctuation of water flow to make the dirt attached to the double-fin net slide down, so that the double-fin net can achieve its own clean structure. Net curtain 1 adopts the filter screen that is not less than 80 orders, can permeable. The net curtain 1 is arranged obliquely, that is, in a non-horizontal state. In other words, the net curtain 1 has a projected area on a vertical plane. N layers of double-fin nets are arranged along the height direction of the net curtain 1, and each layer of double-fin nets includes main wing nets 2 extending along the x-axis direction ...

Embodiment 2

[0045] Embodiment 2 A kind of underwater cage dirt collection device

[0046] Such as Figure 4 to Figure 8 As shown, in this embodiment, the irreversible self-cleaning collection net bag is stabilized underwater by the collection mechanism and the fixing mechanism, and the collection net bag is moved, tightened, and released by the ejection mechanism. The irreversibility referred to here is to make the feces, residual bait and other garbage attached to the collection mechanism unable to flow upwards, thereby avoiding overflow.

[0047] 1. Collection agencies

[0048] Collection mechanism is used for collecting the rubbish that net cage 9 breeds and produces. The collection mechanism takes the collection net bag as the main structure, and the collection net bag includes a bottom pocket and two side stops 11 .

[0049] (1) Collection mesh bag

[0050] The collection mesh bag is an integral structure with an opening at the top, so that the garbage in the net box 9 falls down...

Abstract

The invention discloses a double-wing net rack mechanism for aquaculture and an underwater net cage fish manure waste collection device. The double-wing net rack mechanism for aquaculture comprises anet curtain and double-wing nets, and each double-wing net comprises a main wing net and an assistant wing net. The underwater net cage fish manure waste collection device comprises a bottom bag and two side baffles fixed to the side face of the bottom bag to define a collection net bag with an opening in the top, and the bottom bag is formed by the double-wing net rack mechanism for aquaculture.The double-wing nets can be self-cleaned under the fluctuation action of water flow, and underwater bacteria and algae and parasites are prevented from adhering to the double-wing nets. The double-wing net rack mechanism for aquaculture and the underwater net cage fish manure waste collection device are suitable being used in for lakes, rivers, ponds and other water areas with smooth water flow for collecting manure, residual bait and other wastes in cage culture.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a double-fin net frame mechanism for aquaculture and a fish excrement garbage collection device for underwater net cages. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. Generally, it includes the whole process of growing aquatic products from seedlings under artificial breeding management, and in a broad sense, it can also include the proliferation of aquatic resources. The filter screen used for collection in aquaculture, due to long-term use, causes underwater bacteria, algae and parasites to adhere to the filter screen, so that the filter screen holes are blocked, thereby affecting the normal use of the filter screen. [0003] Cage aquaculture in aquaculture has always been a popular industry. Feces and residual bait produced during moderate aquacultur...
