Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and relates to a fry transfer device for a deep-sea aquaculture vessel, in particular to an elastic lifting bag for automatically dumping fry into a cabin of a aquaculture vessel. Background Art

[0002] Deep-sea waters have significant advantages such as rich fishery resources, high-quality water sources, suitable water temperature and being away from land-based pollution and diseases. They have excellent conditions for large-scale marine aquaculture and logistics processing and supply, and are a new space for the development of modern aquaculture and marine economy.

[0003] Aquaculture vessels are one of the core equipment for developing deep-sea aquaculture projects. They can penetrate deep sea areas that ordinary aquaculture cages cannot reach, and have high economic and social value. The applicant currently operates the world's first 100,000-ton fully enclosed large-scale cruising aquaculture vessel, which is currently the world's largest, most functional, practical and reliable deep-sea aquaculture equipment. The aquaculture vessel is equipped with several large aquaculture cabins in the shape of a "wide-mouth bottle" with an octagonal cross-section. It exchanges water with external seawater through a circulating water pump. The aquaculture water depth of each aquaculture cabin can reach 15 meters, and the number of adult fish raised can reach more than 100 tons. Using aquaculture vessels for fish farming can greatly increase fish production.

[0004] As an important form of aquaculture in modern marine fisheries, aquaculture in the cabin of aquaculture vessels is based on creating a suitable growth environment for marine organisms through swimming operations. During the aquaculture process, the fry need to be transferred to the aquaculture vessel for breeding. Traditional fry transportation usually uses a double-hook crane and a lifting bag to lift the live fish with water. The top of the lifting bag is connected to a main rope, and the bottom is connected to a secondary rope. The main rope and the secondary rope are respectively connected to the two hooks of the double-hook crane. After the lifting bag enters the water, the lifting bag is flipped by operating the secondary rope, thereby dumping the fry from the lifting bag into the aquaculture cabin. However, due to the limitations of the aquaculture vessel's own usage scenario environment, it is not possible to install and use a double-hook crane, and can only use a single-hook crane for operation. The secondary rope can only be pulled manually during operation, which is labor-intensive and poses a great safety hazard. In addition, the force cannot be effectively controlled during manual operation, and the secondary rope can easily damage the bottom of the lifting bag. Utility Model Content

[0005] In response to the deficiencies of the above-mentioned existing technologies, the utility model provides an automatic dumping elastic lifting bag for fish fry entering the cabin of a breeding ship. By optimizing the structure of the auxiliary rope, the scene environment of the breeding ship is effectively utilized, manual participation is reduced, and the simplified operation of transferring fish fry into the cabin is realized.

[0006] An automatic dumping elastic sling bag for fry to enter the cabin of an aquaculture workboat according to the present utility model includes a sling bag and a main towing rope connected to the top of the sling bag, and further includes a secondary rope. One end of the secondary rope is connected to the bottom of the sling bag, and the other end is matched with a buckle at the hatch of the aquaculture cabin. The secondary rope includes a secondary cable and an elastic rope segment connected end to end.

[0007] The present utility model utilizes the physical property of the elastic rope segment to stretch and contract itself, and according to the change in the weight of the material in the sling bag, realizes the flipping movement of the bottom of the sling bag, and further realizes the entry of fry into the cabin.

[0008] As a preferred solution, the elastic rope segment includes a plurality of elastic rubber hoses connected in parallel to form an elastic rubber hose group.

[0009] As a preferred solution, the elastic rope segment further includes transition cables respectively connected to the head and tail ends of the elastic rubber hose group. Due to the physical properties of the elastic rubber hose itself, it is difficult to achieve a tying effect, and the connection between the elastic rubber hose group and other components is realized through the transition cables.

[0010] In specific implementation, the present utility model can adopt the following two technical solutions:

[0011] The first solution is that one of the transition cables of the elastic rope segment is connected to the bottom of the sling bag, and the other transition cable is connected to one end of the secondary cable. The other end of the secondary cable is matched with a buckle at the hatch of the aquaculture cabin. As a preferred solution, the other end of the secondary cable is matched with the buckle at the hatch of the aquaculture cabin through a knot. As a preferred solution, the secondary rope further includes an auxiliary cable. One end of the auxiliary cable is connected to the bottom of the sling bag, and the other end is connected to the secondary cable. The length of the auxiliary cable is longer than the maximum stretched length of the elastic rope segment.

[0012] The second solution is that one of the transition cables of the elastic rope segment is matched with a buckle at the hatch of the aquaculture cabin, and the other transition cable is connected to one end of the secondary cable. The other end of the secondary cable is connected to the bottom of the sling bag. As a preferred solution, one of the transition cables of the elastic rope segment is matched with the buckle at the hatch of the aquaculture cabin through a knot. As a preferred solution, the secondary rope further includes an auxiliary cable. One end of the auxiliary cable is matched with a buckle at the hatch of the aquaculture cabin, and the other end is connected to the secondary cable. The length of the auxiliary cable is longer than the maximum stretched length of the elastic rope segment. As a preferred solution, one end of the auxiliary cable is matched with the buckle at the hatch of the aquaculture cabin through a knot.

[0013] When the utility model is in use, a single-hook crane is used to lift a hanging bag, which is loaded with fry from a live fish transport ship with water, and then lifted to the top of the hatch of the breeding cabin of the breeding ship. The suspended end of the auxiliary rope is manually matched with the buckle of the hatch of the breeding cabin, and then the hook is continuously lowered to drive the hanging bag to move downward. During this process, the elastic rope segment is stretched. When the hanging bag falls into the water, under the action of buoyancy and the inflow of part of the fry and water into the breeding cabin, the elastic rope segment begins to contract and drives the bottom of the hanging bag to flip over, further pulling the hanging bag out of the water, and all the fry in the hanging bag smoothly enter the breeding cabin.

[0014] The advantages of the utility model are:

[0015] (1) The auxiliary rope cooperates with the buckle of the hatch of the breeding cabin, and utilizes the physical properties of the elastic rope segment itself, which stretches and contracts. According to the weight change of the material in the bag, the bottom of the bag is flipped, and the fry are further put into the cabin. The whole process is simpler and faster to operate, which can effectively reduce the risk of fish injury, and the human participation is low, which is conducive to safe operation.

[0016] (2) With the help of the elastic rope segment, the auxiliary rope can achieve slow force during the falling process of the bag, reduce the impact force on the bottom of the bag, extend the use time and reduce costs.

[0017] (3) This device can be applied to various platforms involving the lifting of live fish with water, and its promotion and use in the industry is of great significance. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] Embodiment 1:

[0031] Such as Figure 1 、 Figure 4 and Figure 5As shown in the figure, an automatic dumping elastic sling bag for fry to enter the culture ship's cabin includes a sling bag 4 and a main towing rope 5 connected to the top of the sling bag 4. It also includes a secondary rope 6. One end of the secondary rope 6 is connected to the bottom of the sling bag 4, and the other end is matched with a buckle 7 at the hatch 3 of the culture cabin. The secondary rope 6 includes a secondary cable 61 and an elastic rope segment connected end to end.

[0032] The buckle 7 is a component used to cooperate with the hatch cover at the hatch 3 of the culture cabin. In this regard, the applicant does not make any limitations. For other components at the hatch 3 of the culture cabin that can play a role in limiting and fixing the secondary rope 6, they are all within the scope of protection of this patent.

[0033] In this embodiment, by utilizing the physical property of the elastic rope segment to stretch and contract itself, according to the weight change of the materials in the sling bag 4, the flipping movement of the bottom of the sling bag 4 is realized, and further the fry enter the culture cabin 1.

[0034] As an implementation manner, the elastic rope segment includes a plurality of elastic rubber hoses connected in parallel to form an elastic rubber hose group 62. The following standards can be referred to in the design of this embodiment:

[0035] (1) After wetting the sling bag 4 with seawater, weigh it and its weight is 40 kg.

[0036] (2) According to the tensile force value of the elastic rubber hose stretching multiple and the distance from the hatch 3 of the culture cabin to the water surface, design a suitable stretching length of the elastic rubber hose group 62.

[0037] According to the selected elastic rubber hose, the tensile force value of the single-strand elastic rubber hose stretching multiple is measured as follows:

[0038] Drawing ratio 1 2 3 4 5 6 Weight (kg) 0.0 1.8 3.5 5.0 6.6 8.5

[0039] By combining multiple elastic rubber hoses in parallel, increase the elasticity of the elastic rubber hose group 62 to be greater than 40 kg.

[0040] According to the on-site experiment, the stretching multiple of the elastic rubber hose group 62 should not exceed 3 times. If it stretches too long, the overall length of the secondary rope 6 will be shorter, which is not convenient for workers to match the secondary rope 6 with the buckle 7 at the hatch 3 of the culture cabin.

[0041] If the stretching multiple of the elastic rubber hose group 62 is set at 2 times or less, the combined number of strands of the elastic rubber hose group 62 will increase exponentially. On the one hand, the use cost will increase, and on the other hand, the risk of the elastic rubber hose group 62 breaking will also increase.

[0042] Considering the above conditions and meeting the requirement that the secondary rope 6 is convenient to cooperate with the buckle 7 at the hatch 3 of the culture cabin, set the stretching multiple of the elastic rubber hose group 62 to 3 times, and the natural length of the elastic rubber hose group 62 is set to 60 cm.

[0043] (3) Considering that the suspended bag 4 is affected by water resistance in the breeding tank 1, through on-site experiments, it is found that when the combined number of strands of the elastic rubber hose group 62 is 26 strands, that is, the elastic force is 91 kg, the speed at which the suspended bag is pulled out of the water surface by the elastic rubber hose group 62 is just appropriate.

[0044] As an implementation manner, the elastic rope segment further includes transition cables 63 respectively connected to the head and tail ends of the elastic rubber hose group 62. Due to the physical characteristics of the elastic rubber hose itself, it is difficult to achieve the tying function. The connection between the elastic rubber hose group 62 and other components is realized through the transition cables 63.

[0045] As an implementation manner, one of the transition cables 63 of the elastic rope segment is connected to the bottom of the suspended bag 4, and the other transition cable 63 is connected to one end of the auxiliary cable 61. The other end of the auxiliary cable 61 is matched with the buckle 7 of the breeding tank hatch 3 through a knot 8.

[0046] As an implementation manner, the auxiliary rope 6 further includes an auxiliary cable 64. One end of the auxiliary cable 64 is connected to the bottom of the suspended bag 4, and the other end is connected to the auxiliary cable 61. The length of the auxiliary cable 64 is longer than the length of the elastic rope segment when it is stretched to the maximum. When the elastic rope segment accidentally breaks and is separated from the connected components, the auxiliary cable 64 can ensure that the bottom of the suspended bag 4 is always pulled by the auxiliary rope 6, avoiding safety accidents.

[0047] When this embodiment is in use, as Figure 1 shown, use a single-hook crane 2 to lift the suspended bag 4 to load fry with water from a live fish transport ship, and then lift it above the hatch 3 of the breeding tank of the breeding ship. Manually match the suspended end of the auxiliary rope 6 with the buckle 7 of the breeding tank hatch 3; as Figure 2 shown, the hook continues to lower and drives the suspended bag 4 to move downward until it contacts the water surface. During this process, the elastic rope segment is stretched; as Figure 3 shown, when the suspended bag 4 falls into the water, under the action of buoyancy and the fact that some fry and water start to flow into the breeding tank 1, the elastic rope segment starts to contract and drives the bottom of the suspended bag 4 to flip, further pulling the suspended bag 4 out of the water surface, and all the fry in the suspended bag 4 smoothly enter the breeding tank 1.

[0048] Embodiment 2:

[0049] As Figure 6 and Figure 7 shown, compared with Embodiment 1 in this embodiment, the positions of the auxiliary cable 61 and the elastic rope segment in the auxiliary rope 6 have changed, and the rest is the same as Embodiment 1. Specifically as follows:

[0050] One of the transition cables 63 of the elastic rope segment is matched with the buckle 7 of the breeding tank hatch 3 through a knot 8, and the other transition cable 63 is connected to one end of the auxiliary cable 61. The other end of the auxiliary cable 61 is connected to the bottom of the suspended bag 4.

[0051] As an implementation manner, the secondary rope 6 further includes an auxiliary cable 64. One end of the auxiliary cable 64 is matched with the buckle 7 of the hatch 3 of the cultivation cabin through a knot 8, and the other end is connected to the secondary cable 61. The length of the auxiliary cable 64 is longer than the length when the elastic rope segment is stretched to the maximum. When the elastic rope segment accidentally breaks and is separated from the connected component, the auxiliary cable 64 can ensure that the bottom of the hanging bag 4 is always pulled by the secondary rope 6, avoiding safety accidents.

[0052] The above is a detailed introduction of the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
