Embodiment 1

[0024] Embodiment one, see figure 1 , a self-closing type breeding box, including a net cage 1, a floating box 2 and a closing rod 3.

[0025] Net cage 1 comprises support frame 11 and the culture net 12 of upper end opening. The support frame 11 is a square ring when viewed from above. The front and rear sides of the support frame 11 are provided with sliding holes 13 extending along the left and right directions.

[0026] There are four floating tanks 2. The floating tank 2 is a closed structure. Four buoyant tanks 2 are connected at the four corners of support frame 11.

[0027] Closing bar 3 has a pair and is parallel. The closing rod 3 extends along the front-to-back direction. The front and rear ends of the closing rod 3 are pierced and slidably connected in the sliding hole 13 . The left and right sides of the upper end of the breeding net 12 are correspondingly fixed on two closing rods 3 . One of the pair of closing rods 3 is provided with a locking block 31 ,...

Embodiment 2

[0033] Embodiment two, see Figure 4 The difference with the first embodiment is that it also includes a power coupling mechanism 5, a generator 6, a storage battery 61 and a water electrolyzer 7 connected in sequence. A wave-dissipating wall 15 is provided on the support frame 11 . Oxygen produced by the water electrolysis cell 7 is collected in an oxygen tank 71 . The air outlet of oxygen tank 71 is connected together with the air inlet of air pump 73. The gas outlet of air pump 73 is connected together with the inlet end of oxygen pipe 74. The outlet end of oxygen pipe 74 is inserted in the net cage 1. The hydrogen produced by the water electrolyzer 7 is collected in a hydrogen tank 72 . Hydrogen tank 72 is connected together with gas lamp 9 by hydrogen pipe 91. Gas lamp 9 is positioned at the top of net box 1.

[0034] The wave-dissipating wall 15 is arranged obliquely. On the wave-facing side of the wave-dissipating wall 15 are provided several wave-resistant strip...

Embodiment 3

[0041] Embodiment three, see Figure 7 , The difference with the second embodiment is: there is only one floating tank 2 and it surrounds the culture net 1 around. A closing rod (that is, the closing rod on the right side in the figure) is fixed on the support frame 11 in a pair of closing rods 3 .

[0042] An annular cavity 16 is provided on the support frame 11 . The annular cavity 16 is provided with a water inlet 161 . The water inlet 161 is located on the inner peripheral surface of the annular cavity 161 . The submerged depth detection rod 443 of the support frame and the second float 444 are located in the annular cavity 16 . It can prevent wave interference and cause malfunction. Obviously, the same effect can also be achieved in the case of Embodiment 1 in combination with the solution described in this paragraph.

Abstract

The invention relates to aquaculture equipment, in particular to a self-closing culture cage comprising a net cage and a buoyant box. The net cage comprises a support connected to the buoyant box and a culture net with an open upper end. The open end of the culture net is provided with a pair of closing bars connected with the support. At least one of the closing bars is slidably connected with the support and is provided with a closing bar shifting mechanism. The closing bar shifting mechanism comprises a closing rope with one end connected to the corresponding closing bar, a weight connected to the other end of the closing rope, and a weight balance mechanism; the weight balance mechanism comprises a hanging bar hooked to the closing rope and a first float connected to the hanging bar; the first float locates in the buoyant box; a locking block and a locking channel fitting each other are arranged between transverse bars in a pair. The self-closing culture cage has the advantages that when the buoyant box with water coming in sinks, the opening of the buoyant box can automatically close; the problem that aquatic products cultivated in the culture net escape likely when the existing culture cage submerges in water.

Description

technical field [0001] The invention relates to an aquaculture device, in particular to a self-closing aquaculture box. Background technique [0002] Aquaculture boxes refer to boxes used to raise aquatic products (such as sea cucumbers, fish, shrimp, etc.). According to the needs of breeding, there are structural forms such as suspended on the level and submerged in water. In Chinese patent No. 2012202716008, the authorized announcement date is January 13, 2013, and a kind of aquaculture box is disclosed in the patent document titled "sea cucumber breeding box". Existing floating aquaculture box is made of net cage and floating box, and net cage is made of support frame and the culture net of upper end opening, and the open end of culture net is fixed on the support frame, and support frame floats on the water surface through the float box. When the aquaculture net in the existing aquaculture box is submerged in water due to water inflow into the buoyancy box, the mes...
