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...
