Description

Culture floating body assembly and culture floating body system

Technical Field

The invention relates to a fry breeding structure, in particular to a breeding floating body assembly and a breeding floating body system which float on the water surface, can move and drag and can adjust fry breeding space according to requirements.

Background

The fry culture net cage is a culture net cage which can be used in relatively deep water (usually the depth is more than 20 meters), and is culture equipment which is rapidly developed in the last decade. The net cage structure system and the fishes cultivated by the net cage structure system can be kept safe and innocent even under severe sea conditions by applying high and new technologies such as computers, new materials, pneumatics, corrosion resistance, pollution damage resistance (attachments), ultraviolet resistance (aging resistance) and the like. The method has the advantages that a plurality of countries gradually open, support and encourage deep-water culture, and the implementation of the encouraging policy has important significance for expanding culture water areas and sea areas, relieving environmental pressure, protecting and adjusting marine culture variety structures and promoting scientific deep-water culture. In the last two decades, the large-scale deep-water cage culture represented by Norway has been rapidly and continuously developed all over the world, has achieved remarkable results, and is considered to be the most successful model of the current seawater culture.

In the past, fishermen mostly utilize primary lakes such as lakes and reservoirs to perform fixed-net-cage fishery culture, which not only destroys the ecological environment of primary water, but also causes pollution to water quality by feed, fish feces and the like. Moreover, the arrangement of large-scale net cages also hinders the flow force of water, causes serious negative oxidation water quality, and increases the high risk of eutrophication of lakes and reservoirs. In addition, the traditional aquaculture net cage is fixed in structure and huge in equipment body, so that the traditional aquaculture net cage is not convenient to move to avoid typhoons, hurricanes or cold currents of attack at low temperature, and the space volume (required for survival activities of fishes) in the aquaculture tank cannot be changed when the survival space is insufficient after the fry grows gradually; only by manual method, the partial grown fish can be moved by fishing, and one part of the fish is cut into another aquaculture net cage. This approach is very slow and labor intensive.

Detailed Description

Referring to fig. 1, fig. 1 is a schematic perspective view of a floating body assembly for cultivation according to the present invention when a lifting tank assembly is lowered. As shown in fig. 1, a cultivation float assembly 10 includes a body structure 17, two first buoyancy members 11 and a lift tank assembly 15. The body structure 17 may be a plate, block, boat, dock …, or other structure of varying shapes. The first buoyancy element 11 is fixed on the body structure 17, and may be a buoy, a hollow cylinder, a wood-wood structure, or a ship-shaped dock-shaped structure. The lifter assembly 15 comprises four lifter bars 154, two fixing portions 156 and a bottom frame structure 155, wherein the lifter bars 154 are located at the periphery of the body structure 17 or the first buoyant member 11, and the bottom frame structure 155 is connected below the four lifter bars 154; in a preferred embodiment, a through hole 174 may be formed in the body structure 17 or the first buoyancy element 11, and the lifting rod 154 is located in the through hole 174 and can move up and down and backwards; the four through holes 174 are provided in the embodiment of the present disclosure, the four lifting rods 154 are respectively inserted through the four through holes 174, the fixing portion 156 is located above the through holes 174, each fixing portion 156 is connected to the upper end of the two lifting rods 154, so that the two lifting rods 154 can lift and fall together, and the lifting rods 154 can be prevented from falling down into the water. In addition, an anti-slip pad may be further disposed in the through hole 174 to abut against the lifting rod 154, and the anti-slip pad is preferably made of rubber or plastic, so that the lifting rod 154 can be prevented from sliding up and down arbitrarily due to the frictional resistance of the anti-slip pad.

Referring to fig. 2A to 2B, fig. 2A to 2B are a perspective view and a side view of the floating body assembly for cultivation according to the present invention when a barrier net is hung. As shown in fig. 2A-2B, at least one blocking net 30 may be disposed around the periphery of the lift chute assembly 15, the upper periphery of the blocking net 30 is connected to and fixed to the main body structure 17 or the first buoyant member 11, and the lower periphery of the blocking net 30 is connected to and fixed to the bottom frame structure 155 or supported and supported by the bottom frame structure 155. In this way, the blocking net 30 is detachably attached or abutted to the four lifting rods 154, so that the four lifting rods 154 support or assist in fixing the blocking net 30, and the bottom frame structure 155, the body structure 17 or the first buoyancy element 11 also limit the space above and below the blocking net 30, so that a moving space for survival and stocking of fish fry can be formed, the fish fry cannot escape, and the fish is prevented from leaving the space surrounded and formed by the blocking net 30.

Referring to fig. 2C, fig. 2C is a schematic view illustrating the installation and combination of the elevator chute assembly and the barrier net. As shown in fig. 2C, the bottom frame structure 155 supports and supports the blocking net 30 upwards, and when the lifting chute assembly 15 and the lifting rods 154 lift the fry and fish shoal in the blocking net 30 upwards, the bottom frame structure 155 has enough supporting force to pull all the shoal out of the water.

Referring to fig. 3, fig. 3 is a schematic view illustrating another installation and combination of the elevator car assembly and the barrier net. In other embodiments, as shown in fig. 3, the bottom frame structure 155 can be a rectangular frame structure (a plate without support in the middle), so that the barrier net 30 sinks down to protrude downward from the bottom frame structure 155. The advantage of this structure is that the barrier net 30 can be extended downwards, increasing the volume and space for the survival activity of the shoal.

Referring to fig. 4A-4B, fig. 4A-4B are schematic perspective and side views of the buoyant hull assembly of the present invention during the ascent of the elevator assembly. As shown in fig. 4A-4B, the lift rod 154 and the lift-sink assembly 15 can be relatively displaced with respect to the body structure 17 or the first buoyancy element 11, i.e., the lift rod 154 and the lift-sink assembly 15 can be raised and lowered as required. When the lift rod 154 or the lift tank assembly 15 rises to the top, as shown in fig. 4B, the lowest end of the lift tank assembly 15 or the lift rod 154 (e.g., the bottom frame structure 155 of this embodiment) can be located near the horizontal plane to allow the entire farm float assembly 10 to move about (move to other rivers, lakes, or fish ponds with temperature control devices) to avoid typhoons, hurricanes, or cold weather; in this way, the lifting and lowering tank assembly 15 is lifted to move the whole culture float assembly 10, so that the advantage of reducing the moving resistance (because the force-bearing area facing the water flow is reduced) can be achieved. Of course, another advantage is that the oxygen content in the water is also reduced over a long period of time in the same location, leading to an increase in the mortality rate of the fish; therefore, the whole structure of the aquaculture floating body assembly 10 is moved, so that fresh aquaculture water with high oxygen content can be brought to fish schools in the blocking net 30, and the health of the fish schools is facilitated. In brief, the culture floating body assembly 10 can adjust the culture space for fish school life, and can also move the whole ship to replace the culture place, thereby saving the time-consuming and labor-consuming work of artificial fish school fishing, net passing, fish school transportation and the like, therefore, the invention also has the effect of a 'live fish transport ship', and is very ideal. In addition, the lifting trough assembly 15 is lifted, so that fish fries and fish schools are close to the water surface, fishes can be conveniently caught by fishermen or can be enjoyed by visitors and fished, the purposes of sightseeing culture and teaching are achieved, and economic benefits can be increased.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating the ascending and descending control of the lift rod of the lift chute assembly. As shown in fig. 5, the lift-and-lower assembly 15 further includes or is provided with at least one gear 157, and the gear 157 abuts against the side of the lift rod 154, so that the rotation of the gear 157 can be used to control the up-and-down movement of the lift rod 154 or the lift-and-lower assembly 15.

Referring to fig. 6A, fig. 6A is a schematic view of another embodiment of the buoyant hull assembly of the present invention. As shown in fig. 6A, a propulsion motor 31, a camera 32 and a solar panel 33 are further disposed around the body structure 17 or the first buoyancy element 11. The propulsion motor 31 can be used to propel the floating assembly 10 to move on the water surface, and the camera 32 is used to monitor the size and activity of the fry and fish school in the blocking net 30. The solar panel 33 is used for absorbing sunlight and supplying power to the camera 32 or the propulsion motor 31, and the solar energy can be used for saving energy and reducing fuel consumption, so that the solar energy has the effect of environmental protection. In a preferred embodiment, the propulsion motor 31 is a hybrid type of oil-electric hybrid, which can receive the electric energy output by the solar panel 33, and can also use petrochemical or alcohol, or alkane fuels as the driving energy.

Referring to fig. 6B to 6C, fig. 6B to 6C are another control schematic diagrams for ascending and descending of the elevator assembly. As shown in fig. 6B, the cultivation float assembly 10 further includes at least one second buoyancy element 12, and the second buoyancy element 12 is disposed and connected to the lowest end of the lifting rod 154. Wherein, the second buoyancy element 12 has a cavity 125 therein, and the culture float assembly 10 further includes an inflation/deflation pipeline 16, and the inflation/deflation pipeline 16 is connected or communicated to the cavity 125 of the second buoyancy element 12. In this way, the electric power generated by the solar panel 33 is used to drive an air pump (not shown), so as to drive air into the cavity 125 of the second buoyancy element 12 through the air charging and discharging pipe 16. When the air in the cavity 125 of the second buoyancy element 12 increases, the buoyancy of the second buoyancy element increases, which drives the lifting rod 154 and the lifting tank assembly 15 to move upward. Thus, the lowermost end of the riser assembly 15 or the riser 154 can be positioned near the water level (see FIG. 4B) to facilitate fish capture by fishermen or to allow the entire aquaculture float assembly 10 to be moved about to avoid typhoons, hurricanes, cold weather. In addition, if a little more fish fry is desired to be cultivated, the air in the cavity 125 can be pumped out through the air charging and discharging pipeline 16, or water or liquid can be charged into the cavity 125, so that the air in the second buoyancy element 12 can be reduced, the buoyancy can be reduced, and the lifting rod 154 and the lifting trough assembly 15 can be sunk and moved downwards. Thus, the space in the blocking net 30 is increased, and the volume of the moving space of the fry and the shoal is increased. Thus, the present invention can automatically raise and lower the lifting rod 154 and the lifting trough assembly 15 by the power control of the solar panel 33 or the battery, so as to achieve the technical effect of automatically changing the living space of fish school and fry. In a further embodiment, at least one drainage structure 126 may be disposed at the lowest depression of the second buoyancy element 12 or the cavity 125, and the drainage structure 126 is used for draining and discharging air or liquid in the cavity 125 to assist in controlling the buoyancy of the second buoyancy element 12 or the lift tank assembly 15. The drainage structure 126 may be a pressure relief valve, a vent hole, a drain hole, a flap-type or washer-type through hole …, or other different types. Thus, the buoyancy of the second buoyancy element 12 or the lift tank assembly 15 can be controlled by mechanical means, which is more versatile and easier.

In other embodiments, as shown in fig. 6C, the lift rod 154 is a hollow rod, and the lift rod 154 is connected or connected to the cavity 125 of the second buoyancy element 12; that is, the two air inflation and deflation pipes 16 are respectively communicated and connected with the upper parts of the two lifting rods 154 at the front and the rear of the cultivation floating body assembly 10. In this way, the two air inflation/deflation pipes 16 can also be inflated, evacuated, and filled with water, so that liquid or air can enter and exit the cavity 125 of the second buoyancy element 12 through the interior of the lifting rod 154, thereby achieving the aforementioned "controlling the lifting and lowering of the lifting and lowering assembly 15". Of course, the inflation/deflation tube 16 can also be directly disposed in the lifting rod 154 (fig. 6C does not show this embodiment), so as to indirectly communicate with the cavity 125.

Referring to fig. 7A, fig. 7A is a schematic view of another embodiment of the floating body assembly for cultivation according to the present invention. As shown in fig. 7A, the body structure 17 is further provided with a transparent plate 175 and a closing plate 176, the transparent plate 175 is located at the periphery of the lifting rod 154 or the blocking net 30, and the closing plate 176 is pivoted on the transparent plate 175 and can be opened or closed. Therefore, visitors and fishermen can stand on the transparent plate 175 to enjoy fish or fishing, thereby promoting sightseeing and breeding and increasing economic benefits. Here, the pivot shaft 177 of the closing plate 176 shown in the present embodiment is provided at the middle section of the body structure 17, but in practice, the position and direction of the pivot shaft 177 may be arbitrarily changed depending on the actual space usage on the actual body structure 17.

Referring to fig. 7B, fig. 7B is a schematic structural view of a transparent plate and a closed plate of another embodiment of the floating body assembly for cultivation according to the present invention. As shown in fig. 7B, the closing plate 176 can also be disposed adjacent to the upper periphery of the transparent plate 175, and the closing plate 176 is disposed parallel to the closing plate 176, which can guide the movement of the closing plate 176 by means of a rail or a track groove (not shown) to achieve the opening/closing function. The main body structure 17 may further have a recessed or recessed accommodating structure 178, and when the closing plate 176 moves left and right to open and close, the closing plate 176 may enter the accommodating structure 178 to engage or engage with the accommodating structure 178. Therefore, visitors and fishermen can stand on the transparent plate 175 or the closed plate 176 to enjoy fish or fishing, thereby having the sightseeing effect.

Referring to fig. 8 to 9, fig. 8 to 9 are schematic diagrams illustrating an assembly of the culture float assembly of the present invention into a culture float system. As shown in fig. 8 to 9, a plurality of culture float assemblies 10 can be combined transversely or longitudinally to assemble a culture float system 90; the combination mode is that a plurality of body structures 17 are arranged and connected transversely or longitudinally, and a plurality of cultivation floating body assemblies 10 are connected in a mode of binding ropes, hooks, connecting locks … … and the like. Therefore, a plurality of culture floating body assemblies 10 can be connected into a group, and the situation that the culture floating body assemblies are scattered along with wave fluctuation and difficult to manage is avoided; when the movable type solar energy heat collector needs to be moved to avoid typhoons, hurricanes and low-temperature cold flows, the movable type solar energy heat collector can be moved at one time, and the operation time is saved.

Therefore, the culture floating body assembly 10 or the culture floating body system 90 can move the whole structure of the culture floating body assembly 10 or the culture floating body system 90 at any time to avoid typhoons, hurricanes or low-temperature cold flows and provide the survival rate of the fry; the device can also be used for monitoring the growth conditions of fishes and fry and the volume of the fishes, and then changing the culture space of the fish school life in an automatic control mode; the breeding floating body assembly 10 or the breeding floating body system 90 can be provided for visitors to enjoy fish and fishing, sightseeing breeding is promoted, education is good, and economic benefits are increased. Of course, most importantly, the culture float assembly 10 or the culture float system 90 can increase the culture space volume as the fish grows and becomes larger, so as to be required by the fish growth activities. Therefore, the invention has multiple advantages, is very convenient and has economic benefit.
