Description

Technical Field

[0001] The utility model relates to the field of cage aquaculture, in particular to a floating structure for cage aquaculture. Background Art

[0002] Cage aquaculture generally uses multiple floating boxes / pontoons, which are surrounded by corresponding structures, and corresponding net bags are set around and on the bottom of these floating boxes. During use, the pontoons may be damaged due to aging or collision with sharp objects in the water. In this way, water will flow back into them and cause them to sink. However, since the multiple pontoons are connected together, when one of them is damaged and water enters, the other pontoons can provide some support, making the sinking less obvious and difficult to observe. To this end, we designed a floating structure for cage aquaculture. Utility Model Content

[0003] In order to solve the technical problem that when one of the buoys is damaged and water enters, the other buoys can provide a certain support to it so that its sinking is not particularly obvious, the utility model provides a floating structure for cage aquaculture.

[0004] The utility model adopts the following technical solutions: a floating structure for cage aquaculture, comprising a plurality of floating boxes, the plurality of floating boxes are distributed in a field-shaped structure, and the plurality of floating boxes are connected to a connecting net plate by ropes;

[0005] The interior of the floating box is hollow and designed to form a suspension cavity. A circular hole is opened in the middle of the upper surface of the floating box. A sleeve is integrally formed in the circular hole, and the sleeve extends into the interior of the suspension cavity. A lifting tube is provided inside the sleeve for sliding up and down. The bottom end of the lifting tube is connected to a suspension part, and the bottom of the suspension part is in contact with the bottom end of the interior of the suspension cavity.

[0006] As a further improvement of the above scheme, the connecting mesh plate includes a rectangular frame fixed above the floating box, and the upper and lower surfaces of the rectangular frame are covered with a layer of wire mesh, and the wire mesh is provided with meshes. The structural status of the floating box below can be observed through the mesh, and then it can be determined whether the floating box is damaged and needs to be replaced.

[0007] As a further improvement of the above scheme, the horizontal structure on the top of the floating box is provided with a horizontal part, and the outer surface of the floating box is provided with a plurality of equally spaced reinforcement parts, which are arranged horizontally above the reinforcement parts. The arrangement of the reinforcement parts increases the overall strength of the floating cavity, and the reinforcement parts are used to be connected and fixed to the rectangular frame above, so that there is a certain space between the top of the floating box and the lower surface of the rectangular frame, which is convenient for the up and down movement of the lifting pipe, and further facilitates the observation of whether the floating box is damaged and needs to be replaced.

[0008] As a further improvement of the above-mentioned solution, a screw hole is provided on the right side of the upper surface of the floating box, the screw hole is connected to the inside of the suspension chamber, and a sealing cover is screwed onto the screw hole, the upper end of the seal is not higher than the upper surface of the reinforcement part, and water can be added to or pumped out of the floating box through the screw hole, thereby facilitating the partial sinking of the floating box into the water, and facilitating the installation and replacement of the floating box.

[0009] As a further improvement of the above solution, the suspension part includes a disc arranged inside the suspension cavity, an expansion airbag is connected below the disc, a connecting port is provided above the disc, the lifting tube cavity is aligned with the connecting port, and gas can be filled into the suspension part through the lifting tube and the connecting port, thereby inflating the expansion airbag to facilitate subsequent observation.

[0010] As a further improvement of the above-mentioned solution, when the suspended part contacts the inner wall of the suspension chamber, a sealing plug is installed at the top end of the lifting tube, and the distance between the top end of the sealing plug and the top of the floating box is no greater than the distance between the bottom end of the sleeve and the upper surface of the suspended part. When the suspended part floats upward, the top end of the lifting tube can extend above the floating box, thereby facilitating observation of whether the inside of the floating box is damaged or leaking.

[0011] As a further improvement of the above solution, a piston is provided on the outer ring surface of the lifting tube, and the outer ring surface of the piston is sealed and slidably connected to the inner wall of the sleeve, thereby improving the sealing effect and preventing external water from entering the suspension chamber.

[0012] As a further improvement of the above solution, when the suspension portion contacts the inner wall of the suspension chamber, the distance between the upper surface of the piston and the top end of the sleeve is greater than the distance between the bottom end of the sleeve and the upper surface of the suspension portion. When the suspension portion moves upward, the piston will not extend out of the sleeve, thereby improving the sealing effect.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a floating part that can move up and down inside the floating box. When the floating box breaks, the water entering the floating part can make the floating part float up, and the sealing plug can be placed outside, which is easy to observe and check whether it is broken and needs to be replaced.

[0015] 2. By setting multiple reinforcement parts on the outside of the floating box, the reinforcement parts are connected to the connecting mesh plate, and the screw holes and sealing covers are set together, so that the floating box can sink inward or float upward, thereby facilitating subsequent disassembly and installation.

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figure 1-Figure 5 A cage aquaculture floating structure of this embodiment includes a plurality of floating boxes 2, which are distributed in a field-shaped structure, and a connecting net plate 1 is connected above the plurality of floating boxes 2 by ropes;

[0026] The interior of the floating box 2 is hollow and forms a suspension chamber 25. A circular hole is opened in the middle of the upper surface of the floating box 2. A sleeve tube 23 is integrally formed in the circular hole, and the sleeve tube 23 extends into the interior of the suspension chamber 25. A lifting tube 4 is provided inside the sleeve tube 23 to slide up and down. The bottom end of the lifting tube 4 is connected to the suspension part 3, and the bottom of the suspension part 3 is in contact with the bottom end of the interior of the suspension chamber 25.

[0027] The connecting mesh plate 1 includes a rectangular frame 12 fixed above the floating box 2, and a layer of steel mesh 11 is laid on the upper and lower surfaces of the rectangular frame 12. The steel mesh 11 is provided with meshes, through which the structural status of the floating box 2 below can be observed, and then it can be determined whether the floating box 2 is damaged and needs to be replaced.

[0028] The horizontal structure on the top of the floating box 2 is provided with a horizontal portion 24, and the outer surface of the floating box 2 is provided with a plurality of equally spaced reinforcement portions 21, which are arranged horizontally above the reinforcement portion 21. The arrangement of the reinforcement portion 21 increases the overall strength of the floating chamber, and the reinforcement portion 21 is used to be connected and fixed to the rectangular frame 12 above, so that there is a certain space between the upper part of the floating box 2 and the lower surface of the rectangular frame 12, which is convenient for the up and down movement of the lifting pipe 4, and further facilitates the observation of whether the floating box 2 is damaged and needs to be replaced.

[0029] A screw hole is provided on the right side of the upper surface of the floating box 2, which is connected to the inside of the suspension chamber 25, and a sealing cover 22 is screwed onto the screw hole. The upper end of the seal is not higher than the upper surface of the reinforcement part 21. Water can be added to or extracted from the inside of the floating box 2 through the screw hole, thereby facilitating the partial sinking of the floating box 2 into the water, and facilitating the installation and replacement of the floating box 2.

[0030] The suspension portion 3 includes a disc 31 arranged inside the suspension chamber 25, with an expansion airbag 32 connected to the bottom of the disc 31, and a connecting port 33 provided above the disc 31. The cavity of the lifting tube 4 is aligned with the connecting port 33. Gas can be filled into the suspension portion 3 through the lifting tube 4 and the connecting port 33, thereby inflating the expansion airbag 32 to facilitate subsequent observation.

[0031] When the suspended part 3 contacts the inner wall of the suspended cavity 25, a sealing plug 41 is installed at the top of the lifting pipe 4, and the distance between the top of the sealing plug 41 and the top of the floating box 2 is not greater than the distance between the bottom end of the sleeve 23 and the upper surface of the suspended part 3. When the suspended part 3 floats upward, the top of the lifting pipe 4 can extend above the floating box 2, making it easier to observe whether the inside of the floating box 2 is damaged or leaking.

[0032] A piston is provided on the outer surface of the lifting tube 4 , and the outer surface of the piston is sealed and slidably connected to the inner wall of the sleeve tube 23 , thereby improving the sealing effect and preventing external water from entering the suspension chamber 25 .

[0033] When the suspension part 3 contacts the inner wall of the suspension chamber 25, the distance between the upper surface of the piston and the top of the sleeve 23 is greater than the distance between the bottom end of the sleeve 23 and the upper surface of the suspension part 3. When the suspension part 3 moves upward, the piston will not extend out of the sleeve 23, thereby improving the sealing effect.

[0034] The implementation principle of a cage aquaculture floating structure in the embodiment of the present application is: in actual use, multiple floating boxes 2 and connecting net plates 1 are connected as follows: Figure 1 As shown, the nets are distributed and placed on the water, and the space formed by the connecting net plates 1 is also provided with fishing nets for aquaculture;

[0035] If the flotation box 2 is damaged and leaks water inside, the flotation chamber 25 of the flotation box 2 is provided with a flotation portion 3, and the lower end of the flotation portion 3 is provided with an inflatable airbag 32. The inflatable airbag 32 will float up, thereby causing the lifting tube 4 to be pushed upward as a whole. At this time, when a person standing on the connecting mesh plate 1 walks, he can see the top of the protruding lifting tube 4 (the sealing plug 41 is provided with a bright color different from the flotation box 2 for identification), so as to determine whether the interior is broken or leaking. After that, the person can remove the flotation box 2 from the side.

[0036] When replacing a new floatation box 2, first fill a certain amount of water into the suspension chamber 25 through the screw hole so that the floatation box 2 can be partially submerged in the water. Then, the floatation box 2 can be placed under the connecting mesh plate 1, and the water inside can be pumped out to make the floatation box 2 float. After that, it can be connected and fixed to the connecting mesh plate 1 with a rope.

[0037] By providing a floating portion 3 that can move up and down inside the floating box 2, when the floating box 2 is broken, the water entering the inside can make the floating portion 3 float up, and the sealing plug 41 is placed outside, which is easy to observe and check whether it is broken and needs to be replaced;

[0038] By setting multiple reinforcement parts 21 on the outside of the floating box 2, the reinforcement parts 21 are connected to the connecting mesh plate 1, and the screw holes and sealing covers 22 are set together, so that the floating box 2 can sink inward or float upward, thereby facilitating subsequent disassembly and installation.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
