Description

Technical Field

[0001] The invention belongs to the technical field of marine ship machinery, and in particular relates to a breeding platform structure transformed from a waste ship and a balance monitoring method thereof. Background Art

[0002] At present, the cost of building a new marine aquaculture platform is extremely high. There are cases in the prior art of converting the oil tanks of old oil tankers into marine organism aquaculture tanks, but the large old oil tankers required are expensive and difficult to obtain, and marine organisms can only be cultured in small and closed cabins, which is not conducive to water changes to increase the oxygen content of aquaculture water and remove feces. At the same time, there are a large number of small and medium-sized old ships on the market, which have low purchase costs and maintain normal buoyancy and stability as well as some power performance, including mooring systems. However, the prior art does not transform them into fishery aquaculture platforms due to their small volume.

[0003] At the same time, traditional multi-body breeding platforms are often built using rigid structures such as steel frames. The rigid connection method needs to resist various bending moments, so it has high strength requirements and the construction and installation costs are relatively high.

[0004] Therefore, there is a need for a fish farming platform structure that can use low-cost elastic ropes to connect multiple easily available low-cost small ships together by converting old ships, and ensure its stability and balance under various sea conditions, so as to reduce the construction and installation costs of the fish farming platform. Summary of the invention

[0005] The purpose of the present invention is to provide a breeding platform structure for renovating old ships, which has low construction and installation cost, can be used in a variety of old ships, and has strong stability and balance.

[0006] In order to solve the technical problems existing in the prior art, the present invention adopts the following technical scheme: comprising three old ships, the sterns of the three old ships are connected in pairs using first buoyant elastic ropes, and the bows of the three old ships are all outside the closed area surrounded by the first elastic ropes and the sterns; the bow of each of the old ships is provided with an anchor chain, one end of the anchor chain is provided with an anchor, and the fixed points of the three anchors on the bottom of the water are not collinear; the fishing net is connected to the hull of the old ship or the anchor chain, so as to enclose the breeding space for the marine organisms.

[0007] As a further solution of the present invention: the fishing net is a net bag-like structure with an open upper end and a larger upper portion and a smaller lower portion; the upper open end of the net bag-like structure is fixedly connected to the hull of the ship, and the lower portion of the net bag-like structure is connected to the anchor chain.

[0008] As a further solution of the present invention: a floating body is fixed in the middle of the side of the fishing net.

[0009] As a further solution of the present invention: each of the old ships is provided with a winch, the output end of the winch is connected to the upper end of the traction rope, the lower end of the traction rope is connected to the guide ring, and the anchor chain passes through the guide ring; the lower end of the guide ring is connected to a counterweight through a second elastic rope, and a fixing piece is provided at the lower edge of the fishing net, and the fixing piece is fixed to the traction rope.

[0010] As a further solution of the present invention: the counterweight is placed on the seabed.

[0011] As a further solution of the present invention: a buoyancy airbag and an annular blade are arranged on the counterweight, an air leakage port is opened on the buoyancy airbag, and the second elastic rope passes through the annular blade.

[0012] As a further solution of the present invention: a tension sensor is installed on the first elastic rope. When the tension sensor detects that the tension of the first elastic rope is less than a threshold value, it is determined that the balance of the breeding platform structure is unqualified and the forward thrusters of the three old ships are started to tighten the first elastic rope.

[0013] The present invention reasonably utilizes old ships, connects and combines three ships by using a first elastic rope to enclose a culture platform structure, and simultaneously utilizes anchor chains and anchors of the ships to complete the mooring and fixing of the culture platform structure and the fishing net, thereby reducing construction costs.

[0014] The present invention preferably selects a combination of three ships from among a variety of combinations of the number of old ships. This combination allows three anchoring points to be formed on the seabed even if a simple old ship with only a single anchor is used, thereby ensuring the strength of the anchoring. At the same time, it can ensure that when severe weather at sea comes, as long as the propeller of the old ship is started to keep the first elastic rope in a stretched and straight state, the overall structure of the aquaculture ship can remain stable and no collision will occur between the old ships.

[0015] The present invention fixes a float in the middle of the side of the fishing net. Since the side of the fishing net is inclined, the buoyancy of the float can pull the side of the fishing net upward and tighten the fishing net, thereby expanding the volume of the marine organism breeding space.

[0016] The invention provides a triangular clamping plate which is gradually enlarged from top to bottom on the anchor chain and cooperates with guide rings of different sizes to adjust the bottom height of the fishing net.

[0017] The present invention uses a winch and a traction rope in conjunction with a buoyancy airbag to slowly lower the counterweight along the anchor chain, thereby installing the counterweight and the fishing net, thereby being able to accurately locate the position of the counterweight and reducing damage to the anchor chain and the fishing net during the installation process.

[0018] The second elastic rope can be stretched to allow the weight to be placed on the seabed at different seabed depths, and when the ship is affected by wind and waves and the guide ring moves slightly, the second elastic rope can be stretched to provide a buffer to prevent the weight from being dragged by the guide ring and causing dislocation. When the fishing net needs to be collected, the second elastic rope can be cut by the annular blade under the pull of the winch. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings: Please see attached Figure 1 A culture platform structure transformed from waste ships comprises: three old ships 1, namely old ship 1-1, old ship 1-2 and old ship 1-3, the sterns of which are connected in pairs by first elastic ropes 2 with buoyancy, and the bows of the three old ships 1 are all outside the closed area surrounded by the first elastic ropes 2 and the sterns, and each old ship 1 is provided with an anchor chain 3 at the bow, and an anchor 4 is provided at one end of the anchor chain 3, and the fixed points of the three anchors 4 on the bottom of the water are not collinear; a fishing net 5, which is connected to the hull of the old ship 1 or the anchor chain 3, so as to enclose a culture space for marine organisms.

[0023] The fishing net 5 is a net bag-like structure with an upper end opening, which is small at the top and large at the bottom. The upper open end is fixedly connected to the hull of the old ship 1, and the lower end is connected to the anchor chain 3. A floating body 6 is fixed in the middle of the side of the fishing net 5. Since the fishing net 5 is a net bag-like structure with a small upper part and a large lower part, the side of the fishing net 5 is inclined. Therefore, the buoyancy of the floating body 6 can pull the side of the fishing net 5 upward, so that the fishing net 5 bulges upward, thereby expanding the volume of the marine organism breeding space, and at the same time, the fishing net 5 can be tightened to keep its shape stable and avoid frequent deformation under the action of the ocean current.

[0024] See attached Figure 1 , 2Each old ship 1 is provided with a winch 13, the output end of the winch 13 is connected to the upper end of the traction rope 8, the lower end of the traction rope 8 is connected to the guide ring 9, and the anchor chain 3 passes through the guide ring 9; the lower end of the guide ring 9 is connected to the counterweight 11 through the second elastic rope 10, so as to fix the lower end of the fishing net on the seabed and increase the friction between the structure and the seabed. Due to the rugged seabed terrain, the second elastic rope 10 is appropriately stretched under the influence of the gravity of the counterweight 11, so that the counterweight 11 can be placed on the seabed to adapt to different seabed depths; a fixing member 7 is provided at the lower edge of the fishing net 5, and the fixing member 7 is fixed to the traction rope 8.

[0025] The counterweight 11 is provided with a buoyancy airbag 12 , and an air leakage port is opened on the buoyancy airbag 12 . The buoyancy brought by the buoyancy airbag 12 can slow down the descending speed of the counterweight 11 along the anchor chain 3 , thereby protecting the anchor chain 3 and the fishing net 5 .

[0026] A plurality of triangular clamps 14 are provided on the anchor chain 3, and the triangular clamps 14 gradually increase in size from top to bottom. In the process of the guide ring 9 moving from top to bottom along the anchor chain 3, it can pass through the triangular clamps 14 whose width is smaller than the inner circle diameter, and finally stop at the position of the triangular clamps 14 whose width is larger than the inner circle diameter. By changing the size of the guide ring 9, it can stop at different positions of the triangular clamps 14, so as to adjust the bottom height of the fishing net 5 to adapt to different water depths. Since the bottom edge of the triangular clamps 14 is hinged to the anchor chain 3 so that the triangular clamps 14 can rotate around the anchor chain 3, when the guide ring 9 slides along the anchor chain 3, the triangular clamps 14 can rotate into the circle of the guide ring 9, so that the guide ring 9 can slide smoothly along the bottom edge of the triangular clamps 14 and the anchor chain 3.

[0027] In normal operation, due to the tension of the anchor chain 3, the three old ships 1 tend to move away from each other. The tightened first elastic rope 2 connects the three old ships 1 together to prevent the three old ships 1 from moving away from each other, thereby maintaining the balance between the three old ships 1. However, when there are strong winds and waves, the old ships 1 may move closer to each other due to the wind and wave loads, thereby breaking the balance state and even colliding. A tension sensor is installed on the first elastic rope 2. When the tension sensor detects that the tension of the first elastic rope 2 is less than the threshold, it means that the two adjacent old ships 1 tend to move closer to each other, and the balance of the aquaculture platform structure is judged to be unqualified; otherwise, the balance of the aquaculture platform structure is judged to be qualified.

[0028] When the balance of the aquaculture platform structure is unqualified, the propellers of the three old ships 1 are started to move the three old ships 1 away from each other, and the first elastic rope 2 is tightened to return to a balanced state.

[0029] The reason why the number of old ships set in the present invention is 3 is that: 1. Since it is difficult to limit the floating body to rotate around the anchor with a single anchor structure and it is difficult to limit the floating body to swing left and right with a double anchor structure, the anchors of three old ships can provide at least three anchoring points, which greatly improves the stability of the structure compared with the single anchor point and double anchor point structures. 2. When the number of old ships connected to each other is greater than 3, it may happen that all the first elastic ropes 2 are tightened but the relative positions of the old ships change or even collide, thereby damaging the old ships or fishing nets. However, the simple structure formed by connecting three old ships only needs to ensure that all the first elastic ropes 2 are in a tight state due to the stability of the triangle, so that the relative positions of the three old ships remain unchanged and will not collide with each other.

[0030] The installation and use method of the present invention is as follows: three old ships are driven to the corresponding waters respectively, and anchored and fixed at the anchoring points, and the sterns of the three old ships are connected in pairs by a first elastic rope. The upper end of the fishing net is fixed to the hull of the three old ships, and the lower end is fixed to the traction rope through a fixing piece. The end of the traction rope is connected to the guide ring, and the anchor chain is passed through the guide ring. The lower end of the guide ring is connected to a counterweight through a second elastic rope. At this time, the buoyancy airbag is filled with gas, and the buoyancy generated lifts the counterweight on the water surface. As the gas in the buoyancy airbag slowly leaks from the air leakage port, the buoyancy generated gradually decreases and approaches zero. In this process, the counterweight is driven by gravity to slowly sink to the seabed along the anchor chain together with the guide ring, thereby driving the lower end of the fishing net to be pulled into the seabed, and then the fishing net is unfolded. The ship can be used for work by operators and hatching young fish.

[0031] When the fish in the fishing net are mature, the winch is started to pull the traction rope upward, thereby driving the guide ring to move upward along the anchor chain, so that the fishing net is pulled to the water surface for catching the farmed fish. In this process, the second elastic rope is pulled by the guide ring and tilted to touch the annular blade, thereby cutting the second elastic rope and separating the weight from the guide ring, making it easier to lift the guide ring.

[0032] The above examples are only used to illustrate the present invention, wherein the directions, structures, materials and connection methods of the components may be changed. Any equivalent transformations and improvements based on the technology of the present invention should not be excluded from the protection scope of the present invention.
