Technical Field

[0001] This invention relates to the field of deep-sea fishing equipment technology, and in particular to a live fish transport vessel. Background Technology

[0002] Currently, deep-sea fishing is mainly carried out by deep-sea fishing vessels. Traditional deep-sea fishing vessels have a long operating cycle, which means that the fish caught need to be transported frozen. This not only affects the freshness of the fish and reduces the quality of the fish, but also makes it very inconvenient and time-consuming to handle large quantities of frozen fish, and can damage the surface of the fish. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an improved live fish transport vessel in order to solve the problems existing in the background art. The problem is that the traditional deep-sea fishing vessel has a long operation cycle, which requires the fish caught to be transported frozen. This not only affects the freshness of the fish and reduces the quality of the fish, but also makes it very inconvenient to handle the large amount of frozen fish, which is time-consuming and laborious, and causes damage to the surface of the fish.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a live fish transport vessel, including a transport vessel body, an electric winch lift, a first drive motor, a second drive motor and an electric air pump.

The top surface of the arc-shaped guide cover and the bottom surface of the side sewage trough are both provided with longitudinal assembly holes for the movable assembly of the longitudinal spiral conveying rod. The first drive motor is fixedly installed on the upper end of the arc-shaped guide cover by bolts. The lower end shaft of the first drive motor is axially fixedly connected to the top end of the longitudinal bolt conveying rod.

[0008] An internal transmission chamber is provided on the inner side of the internal assembly blind hole. A bottom transmission gear is sleeved and fixed on the lateral assembly shaft of the transverse spiral conveyor rod inside the internal transmission chamber. A top transmission gear is fixedly sleeved on the outer shaft of the second drive motor. The bottom transmission gear and the top transmission gear are connected by a transmission chain.

[0009] The inner bottom surface of the internal grid plate has a left-position assembly control groove on the left side and a right-position flip sealing groove on the right side.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] Figure 1 , Figure 2 and Figure 5The live fish transport vessel shown includes a transport vessel body 1, an electric winch lift 2, a first drive motor 3, a second drive motor 4, and an electric air pump 55. The transport vessel body 1 has an internal water storage chamber 5 for storing live fish. The internal water storage chamber 5 is equipped with a bottom lifting frame 7 with a bottom buoyancy airbag 6. The bottom surface of the internal water storage chamber 5 has a bottom drain trough 9 with a built-in transverse spiral conveying rod 8 at the bottom angle. The inner side of the internal water storage chamber 5 has a lateral drain trough 11 with a built-in longitudinal spiral conveying rod 10 at the lateral angle.

[0023] Example 1: A longitudinal sealing plate for closure is bolted to the opening on the outer side of the side drain trough 11 located within the internal water storage chamber 5. Openings are only provided at the top and bottom drain trough 9 connection points; the top opening is for discharge, and the bottom opening is for feed. An electric winch lift 2 drives the bottom lifting frame 7 to rise and fall.

[0024] Example 2: When the bottom lifting frame 7 is at the top, people can stand on the top to operate, and then the electric winch lift 2 drives the lifting to clean the internal water storage chamber 5.

[0025] like Figure 3 and Figure 4 As shown, in order to improve lifting stability and reduce lifting resistance, the inner side of the internal water storage chamber 5 has an arc-shaped lateral guide rail 12, and the outer side of the bottom lifting frame 7 is provided with an arc-shaped lateral sliding groove 13 that cooperates with the arc-shaped lateral guide rail 12. The bottom lifting frame 7 is fixedly equipped with an internal grid plate 14 for easy drainage, and a magnetically controlled sealing cover is movably installed on the inner side of the internal grid plate 14.

[0026] The magnetically controlled sealing cover is used to close the drain outlet during descent to reduce the descent pull, improve the stability of descent, and prevent excessive pulling force caused by too fast descent, which would increase the power consumption of the electric winch lift 2. It also facilitates the drainage of dirt from the bottom. During lifting, the drain outlet is opened to reduce the lifting resistance.

[0027] Furthermore, to facilitate bottom assembly, a first lateral mounting bracket for the movable assembly of the transverse spiral conveyor rod 8 is fixed on the inner side of the bottom sludge trough 9 at the connecting end of the lateral sludge trough 11. An internal assembly blind hole for the movable assembly of the transverse spiral conveyor rod 8 is provided on the inner side of the bottom sludge trough 9. Furthermore, to facilitate movable assembly and top-guided slag discharge, an arc-shaped guide cover 16 is fixedly connected to the upper end of the transport vessel body 1 at the upper opening of the lateral sludge trough 11. Longitudinal guides for the movable assembly of the longitudinal spiral conveyor rod 10 are provided on both the inner top surface of the arc-shaped guide cover 16 and the inner bottom surface of the lateral sludge trough 11. To the assembly hole, the first drive motor 3 is fixedly mounted on the upper end of the arc-shaped guide cover 16 by bolts. The lower end shaft of the first drive motor 3 is axially fixedly connected to the top end of the longitudinal bolt conveying rod 10. Furthermore, in order to cooperate with the lateral transmission adjustment, an internal transmission chamber 17 is provided on the inner side of the internal assembly blind hole. A bottom transmission gear 18 is sleeved and fixed on the lateral assembly shaft of the transverse spiral conveying rod 8 inside the internal transmission chamber 17. A top transmission gear 19 is fixedly sleeved on the outer shaft of the second drive motor 4. The bottom transmission gear 18 and the top transmission gear 19 are connected by a transmission chain 20.

[0028] Furthermore, in order to cooperate with electromagnetic control, a left-positioned assembly control groove 21 is provided on the left side of the inner bottom surface of the inner grid plate 14, and a right-positioned flip sealing groove 22 is provided on the right side of the inner bottom surface of the inner grid plate 14. The magnetically controlled sealing cover includes an inner flip plate 23 that is movably assembled in the left-positioned assembly control groove 21 via a lateral movable bracket, an outer closing plate 24 fixed on the outer side of the inner flip plate 23, a magnetically controlled spring 25 fixed on the inner top surface of the inner flip plate 23 and the left-positioned assembly control groove, and an electromagnet 26 for controlling the magnetically controlled spring 25.

[0029] Example: The electromagnet 26 drives the magnetic control spring 25 to contract, thereby causing the inner flip plate 23 to flip upward, and the outer closing plate 24 to flip and insert into the inner grid plate 14 to close the opening, so that the bottom lifting frame 7, the inner grid plate 14 and the outer closing plate 24 form a flat slope.

[0030] Furthermore, to facilitate bottom drainage, the upper surfaces of the bottom lifting frame 7, the internal grating plate 14, and the external closing plate 24 form a drainage slope that gradually decreases in height from the periphery to the bottom drainage trough 9. Furthermore, to facilitate assembly and hoisting, the upper end of the transport ship body 1 is fixedly connected to the top guide rod 28 with built-in guide wheels 27 at the upper opening of the internal water storage chamber 5. The upper surface of the bottom lifting frame 7 is provided with an internal threaded fixing screw hole for the built-in assembly bolt 29 inside the arc-shaped lateral sliding groove 13. The bottom lifting ring 30 moves through the assembly bolt 29.

[0031] Furthermore, in order to facilitate the attraction and gathering of fish and to facilitate the side-pour discharge, the upper surface of the internal grid plate 14 is provided with a top fixing mounting groove for the built-in fish warning light 31.

[0032] Furthermore, in order to cooperate with external inflation and deflation, a bottom limiting plate 32 is fixedly connected to the lower end of the arc-shaped side guide rail 12, and a bottom air inlet pipe 33 is fixedly connected to the upper surface of the bottom limiting plate 32. A bottom mounting hole 34 communicating with the inside of the buoyancy airbag 6 is opened on the lower surface of the bottom lifting frame 7. An electromagnetic air valve 35 is installed inside the bottom mounting hole 34. An electric air pump 55 is fixedly installed on the upper end of the arc-shaped side guide rail 12 by bolts. An internal air supply pipe 36 for connecting the air outlet of the electric air pump 55 and the bottom air inlet pipe 33 is installed inside the arc-shaped side guide rail 12.

[0033] Example: The electric air pump 55 inflates the bottom air inlet pipe 33 through the internal air supply pipe 36. The bottom air inlet pipe 33 is inserted into the bottom mounting hole 34. Then, the solenoid valve 35 is squeezed to control the solenoid valve 35 to start, and the gas is introduced into the buoyancy airbag 6 to assist in lifting the bottom lifting frame 7. When descending, the solenoid valve 35 is activated, the buoyancy airbag 6 receives pressure and exhausts gas outward to reduce the descent resistance. Alternatively, the top exhaust pipe 33 can be set to cooperate with the electric air pump 55 to quickly evacuate and remove air.

[0034] The live fish transport vessel of this invention features an internal water storage chamber 5 for storing live fish. Direct seawater storage enhances the freshness and quality of the caught seafood, extends the fishing cycle, and reduces fishing costs. Within the internal water storage chamber 5, a bottom drainage trough 9 with a built-in transverse spiral conveyor rod 8 and a side drainage trough 11 with a built-in longitudinal spiral conveyor rod 10 are installed. The inclined bottom layout automatically removes sediment from the bottom, ensuring the cleanliness of the internal water chamber 5, maintaining water quality, and extending the survival time of the seafood. A bottom lifting frame 7, controlled by an electric winch elevator 2, is installed inside the internal water storage chamber 5. This facilitates the movement and control of the seafood within the chamber, simplifying loading, unloading, and adjustment, reducing operational difficulty, and saving time and effort. A buoyancy airbag 6 and a magnetically controlled sealing cover are installed at the lower end of the bottom lifting frame 7. These reduce the lifting resistance of the electric winch elevator 2 during lifting and lowering, thereby reducing energy consumption, extending the elevator's service life, and significantly improving safety.

[0035] Example 2: Operational status of live fish transport vessel: (1) Empty cargo at port (2) Departure with empty cargo a) Open cycle b) Closed loop (3) Fish loading operations in fish farms a) Open cycle b) Closed loop (4) Sailing with fish a) Open cycle b) Closed loop (5) Unloading fish at port a) Open cycle b) Closed loop 3) This vessel can also be equipped with a live fish container system, which has many functions and high requirements. It is necessary to carefully study and master the system in conjunction with the equipment data and ship specifications.

[0036] System Introduction: (6) Fish loading and unloading system There are two situations regarding storing fish: a) Fish containing water b) Fish without water packaging Fish unloading situation c) Unloading fish with water-containing compressed air d) Unloading fish with water using a fish-driving board (7) Seawater separation system during fish loading; a) Achieved through the internal grid plate 14 b) Fish can be loaded only into the fish hold. (8) Fish-driving board system: a) Approximately three longitudinal rails are arranged on the internal grating 14 via guide rails. b) Used to herd fish to one place during unloading. (9) Water circulation system: a) When cleaning the fish's skin (fish lice), hydrogen peroxide is added. The dirty water needs to be replaced with clean seawater within approximately 10 minutes. The fish lice are collected at the filter and then discharged after processing.

[0037] b) During normal navigation, in a closed-loop system, the seawater typically needs to be oxygenated and replaced about 3 times per hour.

[0038] c) During closed-loop circulation, seawater in the fish tank is drawn into the filter, then undergoes a CO2 removal process, followed by an oxygenation process, and then enters the fish tank through the bottom and rear inlets.

[0039] d) In open circulation, the old water will be filtered, CO2+UV disinfected and then discharged overboard.

[0040] (10) CO2 removal system: a) When fish produce a significant amount of CO2 in the fish tank, even though they are no longer fed, some secretions will still accumulate, gradually polluting the water. In this case, filtration and CO2 removal procedures are necessary.

[0041] b) CO2 filtration and removal compartments are located on the main deck, two on each side.

[0042] c) This compartment is designed with an open top and supported by pillars at the bottom. It is not included in the gross tonnage.

[0043] (11) Cooling system: a) To maintain the water temperature in the fish hold at a suitable low temperature to prevent fish from becoming more active and suffering greater losses due to increased temperature, this vessel is equipped with two refrigeration systems, each with a refrigeration capacity of approximately 1120KW.

[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
