[0055] Next, the technical solutions of this solution will be further described through specific implementation modes in conjunction with the accompanying drawings.

[0056] A towed floating box device, comprising: a box body 11, a combined ear plate 12, a cable plate 13 and a cross cable bollard 14;

[0057] The combined ear plate 12, the cable plate 13 and the cross cable bollard 14 are respectively installed on the box body 11; the box body 11 is used for carrying the net cage 4; the combined ear plate 12 is arranged on the upper surface and / or side surface of the box body 11; the combined ear plate 12 is provided with a combined hole 123, and the combined hole 123 is used for installing fasteners to connect the combined ear plate 12 to the net cage 4 and / or the combined ear plate 12 of another towed floating box device;

[0058] The cable plate 13 is arranged close to the cross cable bollard 14; the cable hole 18 is horizontally aligned with the cross cable bollard 14; the cable plate 13 is provided with a cable hole 18; the cable hole 18 is used for passing through a first cable 5 and a second cable 6; one end of the first cable 5 is used for connecting the net cage 4, and the other end is used for connecting an auxiliary ship 8; one end of the second cable 6 is used for connecting the cross cable bollard 14, and the other end is used for connecting the auxiliary ship 8.

[0059] This solution provides a towed floating box device, which can meet five operation modes: docking and fixing between the wharf and the net cage, towing of the box body-net cage combination, adjusting the position of the box body in shallow sea, driving piles for the box body and pulling out piles for the net cage, and towing back after the box bodies are combined. It has the advantages of simple structure, low cost, convenient operation and reusable, and solves the problem of large water resistance caused by the existence of the net in the wet towing process of the existing net cage.

[0060] Specifically, the towed floating box device can drive the net cage 4 to move, and the combined ear plate 12 in the box body 11 is provided with a combined hole 123; when it is necessary to connect between two box bodies 11 or between the box body 11 and the net cage 4, only need to lock the combined hole 123 with fasteners; the fasteners are well-known mechanisms, such as bolts, or bolts and nuts. The bolt passes through two combined holes 123 and is fixed by nuts. The combined ear plate 12 can be arranged at any position of the box body 11. More preferably, the combined ear plate 12 is arranged at the upper surface of the box body 11 and both end faces of the length side surface; for example Figure 1, the box body 11 is composed of long boards and square boards. The square boards are respectively arranged at both ends of the long board, and a clamping notch 191 is formed between the long board and the square board; the combined ear plate 12 is arranged on the side surface and the upper surface of the square board; when the box body 11 and the net cage 4 are combined into one, only need to install fasteners in the combination holes 123 of the combined ear plate 12, and fix the combined ear plate 12 to the net cage 4 by the fasteners, so that the box body 11 and the net cage 4 are detachably connected. After the net cage 4 and the box body 11 are fixed, the box body 11 provides fixed positions for the first cable 5 and the second cable 6 to ensure the stable connection between the net cage 4, the box body 11 and the auxiliary ship 8. One end of the first cable 5 is connected to the top of the net cage 4, and the other end is connected to the auxiliary ship 8; one end of the second cable 6 is connected to the cross bollard 14, and the other end is connected to the auxiliary ship 8; the first cable 5 and the second cable 6 pass through the cable holes 18, and the cable holes 18 limit the first cable 5 and the second cable 6. One end of the first cable 5 and the second cable 6 are respectively connected to different objects, which can ensure that when the auxiliary ship 8 fixes its position, the traction force is concentrated on the cable plate 13; at the same time, the first cable 5 and the second cable 6 are respectively limited to different positions, and the two are in independent positions, and there will be no influence when the cables move relative to each other, improving the stability of navigation.

[0061] Preferably, a plurality of support plates 15 are arranged in the box body 11, and an empty cabin 17 is formed between adjacent support plates 15; the support plates 15 are provided with reinforcing ribs 16; the reinforcing ribs 16 are provided with reinforcing surfaces 161 located in different planes, and one reinforcing rib 16 connects different support plates 15 through different reinforcing surfaces 161.

[0062] As Figure 11 , a plurality of support plates 15 are arranged in the box body 11, and an empty cabin 17 structure is formed between the support plates 15. This empty cabin 17 structure can be used to store water to cooperate with the first inclination sensor 2 and the second inclination sensor 3 to absorb and drain water during use, thereby improving the efficiency and reliability of towing. Since water will impact the support plates 15, in this solution, reinforcing ribs 16 are provided at the support plates 15, and the reinforcing ribs 16 are provided with reinforcing surfaces 161 in different aspects; when each reinforcing surface 161 in a different direction is respectively connected to support plates 15 at different positions, the reinforcing ribs 16 can fix a plurality of reinforcing surfaces 161 at the same time, thereby improving the fixing ability between the support plates 15 and preventing the support plates 15 from deforming.

[0063] Preferably, manholes 162 are provided on the surface of the box body 11 and / or the surface of the support plates 15, which is convenient for subsequent installation, maintenance of the box body 11 and local drainage of the box body.

[0064] Preferably, it further includes: a first inclination sensor 2;

[0065] The first inclination sensor 2 is symmetrically installed on the box body 11 respectively; the first inclination sensor 2 is communicatively connected to the tugboat 7, and the first inclination sensor 2 is used to measure the inclination angle α of the box body 11 on the width side and / or the length side; for the two symmetrically distributed first inclination sensors 2, α1 + α2 ∈ [0 - △α, 0 + △α], otherwise the towage is stopped and / or the connection relationship between the box body 11 and the cage 4 is checked; where △α is the allowable error.

[0066] In this solution, the first inclination sensor 2 controls the drainage and water absorption operations inside the box body 11; where the box body 11 can be arranged at the bottom or both sides of the cage 4 as needed, that is, the box body 11 can be single or multiple, as long as the first inclination sensors 2 are arranged in pairs; for example Figure 2 In, the first inclination sensors 2 on the upper and lower sides respectively correspond to the box bodies at different positions, and this pair of first inclination sensors 2 only need to measure the inclination angle α of the width side and / or the length side of the side where they are located. During the operation of the towage floating box device, the paired first inclination sensors 2 will relatively measure the inclination angle α of the width side or the length side of the position where they are located; when the box body 11 and the cage 4 are stably connected, under the action of waves, the box body 11 undergoes pitching on the width side or the length side; such as Figure 7 , the W axis represents the axis of pitching of the box body 11 on the width side; such as Figure 8 , the L axis represents the axis of pitching of the box body 11 on the length side; there is the following relationship between the inclination angle α1 measured by the first inclination sensor 2 on one side and the inclination angle α2 measured by the first inclination sensor 2 on the other side, that is, α1 + α2 ∈ [0 - △α, 0 + △α]; if α1 + α2 does not belong to the above interval, the tugboat is driven to stop the towage and check the connection relationship between the floating box and the cage 4. Thus, the first inclination sensor 2 can ensure that the cage 4 always maintains a balanced state during the towage process.

[0067] More preferably, the first inclination sensor 2 is set with a safety angle β and a calculation error △β; when |α| ≥ β - △β, the first inclination sensor 2 controls the side of the box body 11 with a measured angle greater than 0 to continuously suck in ballast water; the first inclination sensor 2 also controls the side of the box body 11 with a measured angle less than 0 to continuously discharge ballast water.

[0068] Such as Figure 2 , the towage floating box device of this solution is provided with an empty cabin 17, which can be used to store water, and controls the inclination angle α of the box body 11 on the width side and / or the length side by sucking in and discharging water; in the initial state, the first inclination sensor 2 pre-sets the safety angle β and the calculation error △β, which represents the safety angle of the box body 11; such as Figure 2The state when the tugboat is actually towing the cage, the arrow direction is the towing direction, the two sides of a single cage are connected to the box body, and the first inclination sensor 2 between the two sides of the box body is symmetrically arranged; Figure 7 or Figure 8 , if the tilt angle |α1| measured by the first tilt sensor 2 on one side is ≥β-△β, if α1>0, the box body 11 is in a tilted state on that side; at this time, the first tilt sensor 2 is communicatively connected or electrically connected to the pump body, and the seawater is sucked into the empty chamber 17 through the pump body. Under the weight of the seawater, the tilt angle |α1| on that side decreases, so that |α1|<β-△β, thereby realizing the tilt angle adjustment of the box body 11. At the same time, if the corresponding tilt angle |α2| on the other side is ≥β-△β, α2<0, the first tilt sensor 2 on that side can be used to control the corresponding pump body to discharge water, ensuring that |α2|<β-△β, and finally ensuring that the cage 4 always maintains a balanced state during the towing process.

[0069] Preferably, it also includes: a second inclination sensor 3;

[0070] The second inclination sensor 3 is arranged on the box body 11 and is located at one end away from the moving direction; the second inclination sensor 3 is used to measure the offset angle A of the lateral offset of the box body 11; the second inclination sensor 3 is provided with a safety angle γ and an error △γ; when the offset angle |A| of one side ≥γ-△γ, the second inclination sensor 3 controls the side of the box body 11 with a offset angle greater than 0 to continuously inhale ballast water, and also controls the side of the box body 11 with a offset angle less than 0 to continuously discharge ballast water.

[0071] like Figure 9 In addition to the pitching on the width side or the length side, the box 11 will also roll, and the R axis is the roll direction (inward toward the paper surface). During the towing of the box 11, the left arrow is the towing direction. The moving front end of the box 11 is connected to the cable, and the moving rear end is provided with a second inclination sensor 3; when the second inclination sensor 3 detects that the moving rear end has rolled, the second inclination sensor 3 detects the offset angle A of the moving rear end. If the clockwise and counterclockwise roll angles of the offset angle A are too large, their absolute values ​​will be ≥γ-△γ; at this time, the pump bodies at the front and rear positions of the box 11 will correspondingly suck in or discharge seawater into the empty compartment 17, thereby keeping the offset angle A of the front and rear ends of the moving direction adjusted to a normal position, and finally ensuring that the cage 4 always maintains a balanced state during the towing process.

[0072] Preferably, the combined ear plate 12 comprises: an ear seat 121 and a triangular plate 122;

[0073] The ear seat 121 is vertically fixed to the box body 11 and is close to the edge of the box body 11; the ear seat 121 is provided with the combination hole 123; a plurality of the triangular plates 122 are fixed to the ear seat 121, one side of the triangular plate 122 is connected to the ear seat 121, and one side of the triangular plate 122 is connected to the box body 11.

[0074] When the ear seat 121 is vertically fixed and close to the edge of the box body 11, when the box body 11 is combined with another box body 11 (or the net cage 4), it is convenient for assembly. Just directly pass the fastener through the combination hole 123, and then the two box bodies 11 can be fixedly combined through the fastener, or the box body 11 can be fixed to the net cage 4, which is convenient for assembly. In addition, one side of the triangular plate 122 is fixed to the ear seat 121, and the other side is fixed to the box body 11, which can improve the fixing force of the ear seat 121 on the box body 11. The structure in which a plurality of triangular plates 122 are simultaneously connected to the same ear seat 121 can effectively further improve this fixing force.

[0075] Preferably, the box body 11 is provided with a clamping notch 191 for accommodating the net cage 4; the box body 11 is respectively provided with reinforcing openings 192 at both ends of the clamping notch 191; the reinforcing openings 192 are used for fixing the pile feet 42 of the net cage 4;

[0076] The reinforcing opening 192 is provided with an arc surface 193 and a spaced surface 194; the reinforcing opening 192 transitions to the inner side wall of the clamping notch 191 through the arc surface 193; the reinforcing opening 192 transitions to the bottom wall of the clamping notch 191 through the spaced surface 194;

[0077] One end of the reinforcing opening 192 contacts the pile foot 42 through the arc surface 193, and the spaced surface 194 at the other end forms a spaced gap 195 with the pile foot 42.

[0078] The clamping notch 191 can provide a space to accommodate the net cage 4 and limit the pile feet 42 on both sides of the net cage 4 to the reinforcing openings 192; in this solution, as Figure 6 and Figure 9 , the reinforcing opening 192 contacts the pile foot 42 of the net cage 4 through the arc surface 193, can surround the pile foot 42, and prevent the net cage 4 from separating from the box body 11 during towing; and the spaced gaps 195 at both ends can prevent collision with the surface of the pile foot 42 during transportation, especially when the pile foot 42 of this solution is also provided with a rack 43; at the same time, the spaced gap 195 can also be used to optimize the stress concentration phenomenon during towing.

[0079] A lifting type net cage device, comprising: a net cage 4, the above-mentioned towing floating box device 1, the first cable 5, the second cable 6 and the auxiliary ship 8;

[0080] The cage 4 includes: a main cage 41 and a pile leg 42; the pile leg 42 is vertically movably installed on the main cage 41; the main cage 41 is connected to the pile leg 42;

[0081] The first cable 5 and the second cable 6 respectively pass through the cable holes 18;
