Description

Technical Field

[0001] The present invention relates to the technical field of fishery aquaculture, and specifically relates to a foldable floating marine fishery aquaculture platform. Background Art

[0002] A marine fishery aquaculture platform is a facility used for fishery aquaculture in a marine environment. Among them, the foldable floating marine fishery aquaculture platform usually adopts a modular design and consists of multiple foldable units. These units are connected to each other through connection methods such as hinges and joints. When being transported and stored, they can be folded into a compact shape for easy transportation and storage. After arriving at the aquaculture site, they can be quickly unfolded and assembled into a complete aquaculture platform;

[0003] For example, the prior art with the application number CN201910540401.9 relates to a foldable floating marine fishery aquaculture platform, which includes a superstructure and a platform main body. The platform main body is a polygonal structure composed of various rods. The upper part of the vertical column is connected to the superstructure, the lower part of the vertical column penetrates through the control float box and is connected to the lower float box. Multiple groups of struts and connecting rods are evenly distributed around the vertical column. Both ends of the connecting rod are respectively hinged to the top of the control float box and the middle part of the strut. One end of the strut is hinged to the upper part of the platform lower float box, and the other end is connected to the superstructure through a cable. The strut in the form of a folding rod has a fixed angle, and the netting is connected between the adjacent struts along the circumference;

[0004] Through actual use of the above prior art, it is known that it mainly makes the connecting rod and the strut expand by pushing the control float box downward, and finally unfolds the netting. However, in use, the structure in which the netting unfolds like an umbrella will be affected by external forces such as wind and waves in the marine environment, resulting in shaking and a large inclination angle, causing fish to gather on one side and squeeze each other, and causing damage to the aquaculture equipment and fish. Therefore, according to the actual use situation, the above prior art is improved. Summary of the Invention

[0005] In view of the above problems, the present invention aims to provide a foldable floating marine fishery aquaculture platform.

[0006] To achieve the technical purpose, the solution of the present invention is: a foldable floating marine fishery aquaculture platform, including a vertical rod. A rain cloth is arranged on the periphery of the vertical rod, and L-shaped support rods and connecting rods are hinged between the inner side of the rain cloth and the vertical rod for folding the rain cloth. At least three groups of counterweight members are arranged on the periphery of the rain cloth. Each group of counterweight members includes a steel wire rope, a floating cylinder and a counterweight block. The upper end of the steel wire rope is fixed to the outer surface of the rain cloth, the lower end of the steel wire rope is fixed to the floating cylinder, and a counterweight block is arranged inside the floating cylinder.

[0007] Preferably, a pushing block is slidably arranged on the periphery of the vertical rod, a base is fixed at the lower end of the vertical rod, and the lower surface of the base is fixed to the bottom wall of the tarpaulin by rivets; at least six cloth sleeves are integrally arranged on the inner wall of the tarpaulin, and an L-shaped support rod is inserted through each cloth sleeve. One end of each L-shaped support rod is hinged through a pin rod base, and a connecting rod is hinged between the upper surface of each L-shaped support rod and the periphery of the pushing block through a pin rod; a blocking block is sleeved on the periphery of the vertical rod, the lower surface of the blocking block is fixed to the upper surface of the base, and the upper end of the blocking block abuts against the lower end of the pushing block.

[0008] Preferably, at least six threaded cylinders are integrally arranged on the outer surface of the tarpaulin, and a fixing block is integrally arranged between each threaded cylinder and the outer surface of the tarpaulin. A steel wire rope is arranged in the threaded cylinder in a threaded manner.

[0009] Preferably, the lower end of the steel wire rope is tied to the upper end of the floating cylinder through a pull ring, and an annular groove is arranged in the floating cylinder.

[0010] Preferably, a counterweight block is slidably arranged in the annular groove. The counterweight block is arc-shaped, and a screw rod is arranged in the floating cylinder in a threaded manner. One end of each screw rod abuts against the outer side of the counterweight block.

[0011] Preferably, at least six drain holes are arranged in the tarpaulin, and a drainage member is arranged in each drain hole. The drainage member includes an elastically arranged sealing cover, and the inner side of each sealing cover abuts against the outer edge of the drain hole.

[0012] Preferably, a sealing ring is inlaid on the inner side of the sealing cover, and the inner side of the sealing ring abuts against the outer edge of the drain hole.

[0013] Preferably, a baffle is adhered to the inner wall of the drain hole, and a round rod passes through the baffle. One end of the round rod is integrally arranged with the inner side of the sealing cover, and a spring is sleeved on the periphery of the round rod. A spring is fixed between the inner side of the sealing cover and the outer side of the baffle.

[0014] Preferably, through holes are annularly arranged in the baffle, and a limiting block is integrally arranged at one end of the round rod;

[0015] Beneficial effects:

[0016] 1. Three groups of counterweights are added to the periphery of the rain cloth of this device. In each group of counterweights, the floating barrels all pull the periphery of the rain cloth through steel wires. At the same time, counterweight blocks can be detachably arranged in each floating barrel, and the steel wires play a role in restraint and connection. When the rain cloth has a tendency to shake or tilt under the action of external forces such as wind and waves, the steel wire will transmit the force to the floating barrel and the counterweight block. Due to its own weight and inertia, the counterweight block will resist the shaking and tilting of the rain cloth, and the movement range of the rain cloth is restricted through the restraint of the steel wire, so that it remains within a small shaking and tilting angle. In this way, in the marine environment, when external forces such as wind and waves try to push the rain cloth to make it shake or tilt, the rain cloth is less likely to be pushed by the wind and waves, so as to maintain a relatively stable state, and it can avoid large tilts of the rain cloth and the situation of fish aggregating and squeezing each other.

[0017] 2. In addition, when it rains or for other reasons, the water level inside the rain cloth rises and enters the drain hole, the water exerts pressure on the elastic sealing cover, causing it to drive the round rod to move outwards and pull the spring at the same time, and the sealing cover is separated from the drain hole, thus realizing automatic drainage. This can avoid excessive water accumulation inside the rain cloth, prevent the rain cloth from sinking or being damaged due to excessive water weight, and at the same time can also maintain a relatively stable water level inside the rain cloth, providing a suitable living space for fish.

[0018] 3. In the initial stage of aquaculture, there may be fewer fish and lighter weights placed inside the rain cloth. At this time, lighter counterweight blocks can be used to keep the device in an appropriate floating state. As the fish grow and their weights increase, in order to maintain balance, heavier counterweight blocks can be replaced to adapt to aquaculture environments of different weights.

[0027] The following further elaborates on the invention of the present application in conjunction with the attached drawings and specific embodiments. For a clear and complete description of the technical solution, the following embodiments are selected for illustration; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the scope of protection of the present invention.

[0029] As Figures 1 to 7 shown, the embodiment of the present invention provides a foldable floating marine fishery breeding platform, including a vertical pole 1. A tarpaulin 2 is arranged on the periphery of the vertical pole 1, and an L-shaped support rod 3 and a connecting rod 4 are hinged between the inner side of the tarpaulin 2 and the vertical pole 1 for folding the tarpaulin 2. At least three groups of counterweight members 7 are arranged on the periphery of the tarpaulin 2; each group of counterweight members 7 includes a steel wire rope 71, a floating cylinder 72 and a counterweight block 73. The upper end of the steel wire rope 71 is fixed to the outer surface of the tarpaulin 2, and the lower end of the steel wire rope 71 is fixed to the floating cylinder 72. A counterweight block 73 is arranged inside the floating cylinder 72. Anticorrosion coatings can be arranged on the inner and outer surfaces of the tarpaulin 2 and the outer surfaces of the L-shaped support rod 3 and the connecting rod 4;

[0030] The anti-corrosion coating can be an epoxy coating, which has good adhesion and can firmly adhere to the metal surface; it has strong chemical corrosion resistance and has good resistance to seawater, salt spray, etc.; it has excellent mechanical properties, with a certain hardness and toughness, and can effectively protect the substrate material. It is widely used for the surface protection of steel structures such as ships and offshore platforms; it can also be a polyurethane coating with excellent weather resistance, which can be exposed to the marine environment for a long time without obvious aging and discoloration; it has good water resistance and can effectively prevent the penetration of seawater; it has good flexibility and can adapt to the deformation of the substrate material in the marine environment. It is commonly used for the protection of offshore wind power equipment, port facilities, etc.; and it can be a zinc-rich coating containing a large amount of zinc powder. Zinc has a more active chemical property than iron and can preferentially sacrifice itself to protect the substrate metal in the seawater environment; it has good electrical conductivity and can form effective cathodic protection; it has good adhesion to the steel surface. It is one of the commonly used anti-corrosion coatings for marine steel structures, such as the hull of a ship, marine pipelines, etc.;

[0031] Reference Figure 1 and Figure 2 A push block 10 is slidably arranged on the periphery of the vertical rod 1. A base 11 is fixed at the lower end of the vertical rod 1. The lower surface of the base 11 is fixed to the bottom wall of the tarpaulin 2 by rivets; at least six cloth sleeves 9 are integrally arranged on the inner wall of the tarpaulin 2. An L-shaped support rod 3 is inserted into each cloth sleeve 9, which can separate the tarpaulin 2 from the L-shaped support rod 3 for easy drying and maintenance. One end of each L-shaped support rod 3 is hinged to the base 11 through a pin rod. A connecting rod 4 is hinged between the upper surface of each L-shaped support rod 3 and the periphery of the push block 10 through a pin rod; A stop block 12 is sleeved on the periphery of the vertical rod 1. The lower surface of the stop block 12 is fixed to the upper surface of the base 11, and the upper end of the stop block 12 abuts against the lower end of the push block 10 to limit the push block 10.

[0032] At least six threaded cylinders 76 are integrally arranged on the outer surface of the tarpaulin 2, and a fixing block 8 is integrally arranged between each threaded cylinder 76 and the outer surface of the tarpaulin 2. A steel wire rope 71 is threadedly arranged in the threaded cylinder 76 for easy replacement. The lower end of the steel wire rope 71 is tied to the upper end of the floating cylinder 72 through a pull ring. An annular groove 75 is arranged in the floating cylinder 72. A counterweight block 73 can be slidably arranged in the annular groove 75 and the counterweight block 73 can be added. The counterweight block 73 is arc-shaped. A screw rod 74 is threadedly arranged in the floating cylinder 72. One end of each screw rod 74 abuts against the outside of the counterweight block 73 to ensure the stability of the counterweight block 73. Each floating cylinder 72 can hold up to four counterweight blocks 73;

[0033] The buoy 72 is made of high-density polyethylene (HDPE), which has excellent chemical corrosion resistance, can resist the erosion of seawater, salt spray, acids and alkalis, etc., has a long service life, and reduces the maintenance and replacement costs caused by corrosion. The buoy 72 made of this material has high toughness and impact resistance, can withstand the impact of external forces such as wind waves and water currents in the marine environment, and is not easily broken or damaged. The density of HDPE is relatively low, and it can provide greater buoyancy under the same volume, which can effectively support the weight of the rain cloth 2 and the aquaculture facilities. The HDPE material itself is non-toxic and will not pollute the marine environment and aquaculture organisms, meeting the environmental protection requirements;

[0034] The counterweight 73 is made of concrete, with relatively low cost, easy-to-obtain raw materials and simple manufacturing process. It has a relatively large density and can provide a large weight in a relatively small volume, effectively increasing the stability of the aquaculture platform. It has good durability and can resist the erosion of seawater and the influence of the marine environment; at the same time, the weight of the counterweight 73 depends on multiple factors, such as the scale of the aquaculture platform, the size and shape of the rain cloth 2, the number and specifications of the buoys 72, the marine environmental conditions, etc. Generally speaking, the weight of a single counterweight 73 may be between dozens of kilograms and several tons. For example, the counterweight 73 of a small aquaculture platform may weigh 50-100 kilograms each, while the counterweight 73 of a large aquaculture platform may reach 1-2 tons or even heavier, and can be selected according to the actual situation.

[0035] At least six drainage holes 6 are provided in the rain cloth 2, and a drainage member 5 is provided in each drainage hole 6. The drainage member 5 includes an elastically arranged sealing cover 52, and the inner side of each sealing cover 52 abuts against the outer edge of the drainage hole 6. A sealing ring 54 is inlaid on the inner side of the sealing cover 52, and the inner side of the sealing ring 54 abuts against the outer edge of the drainage hole 6. A baffle 51 is adhered to the inner wall of the drainage hole 6, and a round rod 55 passes through the baffle 51. One end of the round rod 55 is integrally provided with the inner side of the sealing cover 52, a spring 56 is sleeved around the round rod 55, and the spring 56 is fixed between the inner side of the sealing cover 52 and the outer side of the baffle 51. A through hole 53 is annularly arranged in the baffle 51, and the diameter of the through hole 53 is smaller than that of the fry, which can block the fry and prevent the loss of fry; a limiting block 57 is integrally provided at one end of the round rod 55.

[0036] Working principle: During the use of this device, first push the push block 10 downward to make the connecting rod 4 push the L-shaped support rod 3 to expand and drive the rain cloth 2 to unfold, and then it can be placed on the water surface for use; three groups of counterweight members 7 are added to the periphery of the rain cloth 2 of this device. In each group of counterweight members 7, the buoy 72 pulls the periphery of the rain cloth 2 through the steel wire rope 71, and at the same time, a counterweight 73 can be detachably arranged in each buoy 72;

[0037] During the use of the tarpaulin 2, the counterweight 73 increases the overall weight of the tarpaulin 2 and the buoy 72 system, enabling the tarpaulin 2 to have stronger stability. By arranging the counterweight 73 inside the buoy 72, the buoy 72 itself has a certain buoyancy, which can make the tarpaulin 2 float on the water surface. The weight of the counterweight 73 generates a downward pulling force on the buoy 72. When the buoyancy of the buoy 72 balances with the gravity of the counterweight 73, the tarpaulin 2 can float stably on the water surface. Under the action of wind and waves, this balance plays a buffering and stabilizing role. At the same time, the buoy 72 is fixed to the periphery of the unfolded tarpaulin 2 through the steel wire rope 71, and the steel wire rope 71 plays a role of restraint and connection. When the tarpaulin 2 has a tendency to shake or tilt under the action of external forces such as wind and waves, the steel wire rope 71 will transmit the force to the buoy 72 and the counterweight 73. Due to its own weight and inertia, the counterweight 73 will resist the shaking and tilting of the tarpaulin 2, and limit the movement range of the tarpaulin 2 through the restraint of the steel wire rope 71, keeping it within a small shaking and tilting angle. In this way, in the marine environment, when external forces such as wind and waves attempt to push the tarpaulin 2 to make it shake or tilt, the tarpaulin 2 is less likely to be pushed by the wind and waves, thus maintaining a relatively stable state, and avoiding large tilts of the tarpaulin 2 and the situation of fish gathering and squeezing each other.

[0038] In addition, when it rains or for other reasons, the water level inside the tarpaulin 2 rises and enters the drain hole 6. The water presses on the elastic sealing cover 52, causing it to drive the round rod 55 to move outwards and pull the spring 56 at the same time. The sealing cover 52 separates from the drain hole 6, thus realizing automatic drainage. This can prevent excessive water accumulation inside the tarpaulin 2, prevent the tarpaulin 2 from sinking or being damaged due to excessive water weight, and at the same time maintain a relatively stable water level inside the tarpaulin 2, providing a suitable living space for fish. After the water level inside the tarpaulin 2 is lower than the drain hole 6, the sealing cover 52 will be automatically reset under the pulling force of the spring 56 and press tightly against the drain hole 6 for sealing.

[0039] In the initial stage of aquaculture, there may be fewer and lighter fish placed inside the tarpaulin 2. At this time, a lighter counterweight 73 can be used to keep the device in an appropriate floating state. As the fish grow and their weight increases, in order to maintain balance, the screw 74 can be turned to loosen the original counterweight 73 and replace it with a heavier counterweight 73 to adapt to the aquaculture environment with different weights of fisheries.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention should be included within the protection scope of the technical solution of the present invention.
