Description
Technical Field
[0001] This invention relates to the field of marine vessel technology, and more particularly to a vessel-to-shore fish transport device and method. Background Technology
[0002] In traditional fishing operations, transferring the fish from the hold of a fishing boat to shore after it docks is a laborious and time-consuming task.
[0003] Common transfer methods usually involve manual handling, mechanical hoisting, or conveyor belt transport. These methods are characterized by high labor intensity, low efficiency, and easy damage to fish. During mechanical hoisting, fish accumulate in the net, causing crushing damage, and require secondary handling to get them ashore. Basic conveying equipment is difficult to adapt to large height differences, and fish suffer from dehydration, friction, and damage during transport, failing to meet higher actual transfer requirements. Therefore, improvements are necessary. Summary of the Invention
[0004] This invention provides a fish ship-to-shore transport device and method that can effectively improve the efficiency of fish transfer from ship hold to ship-to-shore, greatly reduce manual intervention and labor intensity, reduce damage to fish during the transfer process, adapt to different working environments, and meet higher practical transfer needs. It solves the technical problems of existing fish transfer methods that are relatively simple, involve high labor intensity and low efficiency, are prone to damage to fish, and whose basic transfer equipment cannot adapt to the height difference between the ship and the shore, and still suffer from fish damage during the transfer process, thus failing to meet higher practical transfer needs.
[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: a fish boat-to-shore transport device and method, comprising a hull moored at the shore, a fish-receiving bucket placed on the shore, a mounting base provided in the cabin of the hull, and a transport pipe provided on the mounting base. The transport pipe is formed by an L-shaped connection between a vertically extending lifting pipe and a horizontally extending fish-transporting pipe, and the lifting pipe communicates with the internal channels of the fish-transporting pipe. A lifting device extending to the bottom of the cabin is provided in the lifting pipe, which lifts the fish in the cabin to the top and transports them from the fish-transporting pipe to the fish-receiving bucket. The present invention connects the spatial difference between the bottom of the cabin and the fish-receiving bucket on the shore through the transport pipe. The L-shaped transport pipe, in conjunction with the lifting device, can lift the fish and seawater in the cabin to the top and transport the fish from the fish-transporting pipe to the fish-receiving bucket, which can greatly improve the efficiency of fish transport, reduce the workload of manual operation, and reduce the squeezing and damage to the fish during the transport process.
[0006] Preferably, the lifting device includes a lifting chain installed inside the lifting pipe, driven by a lifting motor at the top. Several fish-lifting plates are spaced apart on the lifting chain, each with a fish-lifting cavity. The side wall of the fish-lifting plate closest to the conveying pipe is open, and the open side is close to the inner wall of the conveying pipe during operation. The lifting chain allows for continuous heavy-duty operation, and the fish-lifting cavity of the fish-lifting plate can hold a certain amount of fish and water at a time, resulting in high lifting efficiency. The open structure on the side prevents fish from leaking out during lifting and ensures that fish can be discharged from the side opening when the lifting reaches the top.
[0007] Preferably, the bottom of the fish-lifting cavity is slightly inclined, with the inclination trend decreasing towards the side closer to the fish conveying pipe and gradually flattening out at the end. Fish tend to concentrate at the bottom of the fish-lifting cavity of the lifting plate, and the inclined structure allows the fish to slide out more smoothly when tilted, reducing impact and jamming.
[0008] Preferably, the lifting device further includes a baffle rotatably mounted on top of the lifting pipe. The baffle hangs vertically at the turning point of the lifting chain. When the fish-lifting plate reaches the top and begins to tilt, the baffle guides all the fish into the inlet of the fish conveying pipe. The baffle is mounted on top of the lifting pipe via a pivot and works with the fish-lifting plate to guide the fish into the conveying pipe. It can reciprocate and reset in conjunction with the fish-lifting plate without affecting its operation. This effectively prevents fish from splashing or falling back into the lower part of the lifting pipe during tilting, ensuring the directionality and integrity of the conveying process and improving conveying efficiency.
[0009] Preferably, the bottom of the lifting pipe is connected to two extension plates, and the top of the lifting pipe and the extension plates are equipped with two rotating shafts. Each rotating shaft is equipped with a lifting gear, which meshes with the inner side of the lifting chain. The lifting chain can be driven to rotate in a closed loop by the lifting motor, the rotating shafts, and the lifting gears.
[0010] Preferably, the lifting device further includes several airbags spaced apart at the top of the fish transport pipe. The airbags supply gas via air pipes extending to the hull. Adjacent airbags are connected by air supply pipes, and the airbags are sealed at the top of the fish transport pipe via three-way or double-way bases. The compressed air-filled airbags provide buoyancy, partially offsetting the weight of the pipe and the fish / water, reducing the load on the mounting base, and preventing the entire fish transport pipe from sinking due to gravity, thus ensuring overall stability during transport. The three-way and double-way bases connect two airbags, air pipes, and air supply pipes, ensuring a seal and allowing for simultaneous inflation or deflation of two airbags. Inflation of the airbags can be achieved using an air pump pre-placed on the ship.
[0011] Preferably, the fish transport pipeline has a water inlet at the top, and seawater can be introduced into the pipeline through a water pipe and a water pump connected to the inlet. A water pump is installed on the ship, and seawater is connected to the inlet via a water pipe. The pump pumps the seawater into the fish transport pipeline, continuously flushing it and effectively preventing fish from accumulating inside. By utilizing the existing seawater in the working environment for flushing, there is no need for a separate power water source, achieving on-site material utilization.
[0012] Preferably, the mounting base is either a fixed base or a rotating base, with the conveying pipeline fixedly or rotatably mounted on the hull. Different types of mounting bases can be selected according to requirements. Rotary mounting bases achieve rotation through gear meshing and motor drive, allowing adjustment of the overall angle and position of the conveying pipeline.
[0013] Preferably, the fish transport pipe is either a straight-through pipe or a telescopic pipe. Different structures of fish transport pipes can be selected according to different actual needs. When the fish transport pipe is a straight-through pipe, a rotating mounting base is selected accordingly, so that the overall angle and position of the transport pipe can be adjusted as needed. If the fish transport pipe is telescopic, a fixed mounting base can be selected. The fish transport pipe can be extended and retracted to save space and can be stored on its own.
[0014] As a preferred method, before operation, the vessel is brought ashore so that the outlet of the fish transport pipe connects to the fish receiving bucket. A pre-installed air pump on board then pumps hydrogen or helium into the air bladder. During transport, a lifting motor drives a lifting chain to rotate counter-clockwise. As the chain rotates, a fish-lifting plate simultaneously stores the fish and seawater stored in the hold within the lifting chamber. The plate lifts the fish upwards, and when it reaches its highest point, it gradually tilts. Combined with a baffle, this ensures the fish are smoothly transferred into the fish transport pipe. Simultaneously, seawater is injected into the pipe from the inlet, continuously flushing it and preventing fish from remaining inside.
[0015] Therefore, the fish ship-to-shore transport device and method of the present invention have the following advantages: they can effectively improve the efficiency of fish transfer from the ship's hold to the shore, greatly reduce manual intervention and labor intensity, reduce damage to fish during the transfer process, adapt to different working environments, and meet higher actual transfer requirements.

Detailed Implementation
[0025] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0026] Example 1: like Figure 1 and 2 As shown, a fish boat-to-shore transport device and method includes a boat hull 1 moored at the shore, a fish-catching bucket 2 placed at the shore, and a fixed mounting base 3 installed in the cabin of the boat hull 1, on which a transport pipe is installed.
[0027] The conveying pipeline is formed by the vertically extending lifting pipe 4 and the horizontally extending fish conveying pipe 5 connected in an "L" shape. The fish conveying pipe 5 is an adjustable-length telescopic pipe. The inner pipe of the fish conveying pipe 5 can slide and extend within the outer pipe. The lifting pipe 4 is connected to the internal channel of the fish conveying pipe 5.
[0028] The top of the fish transport pipe 5 is provided with a water inlet 6. Seawater can be introduced into the fish transport pipe 5 through a water pipe connected to the water inlet 6 and a water pump placed on the hull 1.
[0029] The lifting pipe 4 is equipped with a lifting device that extends downward to the bottom of the cabin. The lifting device lifts the fish in the cabin to the top and transports them from the fish transport pipe 5 to the fish receiving bucket 2.
[0030] The lifting device includes a lifting chain 7 installed inside the lifting pipe 4, which is driven by a lifting motor 8 at the top; several fish lifting plates 9 are installed at intervals on the lifting chain 7.
[0031] Two extension plates 10 are connected and installed at the bottom of the lifting pipe 4. Two rotating shafts 21 are installed at the top of the lifting pipe 4 and on the extension plates 10. Each rotating shaft 21 is equipped with a lifting gear 11. The lifting gear 11 meshes with the inner side of the lifting chain 7. The lifting chain 7 is driven to rotate by the lifting motor 8, the rotating shaft 21, and the lifting gear 11.
[0032] Each fish-lifting plate 9 has a fish-lifting cavity 12, and the side wall of the fish-lifting plate 9 closest to the conveying pipe is an open structure. During operation, the open side of the fish-lifting plate 9 is close to the inner wall of the conveying pipe.
[0033] The bottom of the fish lifting chamber 12 has a slight sloping trend, which is downward towards the side closer to the fish conveying pipe 5, and gradually becomes flat at the end.
[0034] The lifting device also includes a baffle 13 that is rotatably installed on the top of the lifting pipe 4. The baffle 13 is vertically positioned at the turning point of the lifting chain 7. When the fish lifting plate 9 reaches the top and begins to tilt, the baffle 13 is used to guide all the fish into the inlet of the fish conveying pipe 5.
[0035] The lifting device also includes two airbags 14 spaced apart on the top of the fish transport pipe 5. The two airbags 14 are sealed on the outer and inner pipes of the fish transport pipe 5 respectively through a three-way base 15 and a double-way base 16. The airbags 14 deliver gas through an air pipe 17 extending to the hull 1, and adjacent airbags 14 are connected by an air pipe 18.
[0036] Before starting work, bring the hull 1 to shore, pull out the inner layer of the fish transport pipe 5, connect the outlet of the fish transport pipe 5 to the fish receiving bucket 2, and use the pre-placed air pump on the ship to transport hydrogen or helium into the air bag 14, and adjust the angle of the fish transport pipe 5 so that it tilts slightly downward.
[0037] On board, staff used water pumps and pipes to pump nearby seawater from inlet 6 into fish transport pipe 5, continuously flushing the pipe.
[0038] During transport, the lifting motor 8 drives the lifting chain 7 to rotate counterclockwise continuously. As the lifting chain 7 rotates, the fish lifting plate 9 stores the fish and seawater stored in the hold in the fish lifting chamber 12 at the same time. The fish lifting plate 9 lifts the fish upwards. When the fish lifting plate 9 moves to the top, it will gradually tilt. With the help of the baffle 13, it can ensure that the fish poured out can smoothly enter the fish transport pipe 5. With the seawater constantly flushing the fish transport pipe 5, the fish in the pipe will not be stuck in the fish transport pipe 5.
[0039] After the work is completed, the fish transport pipe 5 can be retracted and the gas in the airbag 14 can be released, allowing for normal navigation.
[0040] Example 2: like Figure 3 and 4 As shown in Figures 5, 6, 7, and 8, a fish boat-to-shore transport device and method includes a hull 1 moored at the shore, with a fish-catching bucket 2 placed on it; a rotary mounting base 3 is installed in the cabin of the hull 1, and a drive gear 19 and a drive motor 20 that mesh with the rotary mounting base 3 are installed on the hull 1, and a transport pipe is installed on the mounting base 3.
[0041] The conveying pipeline is formed by the vertically extending lifting pipeline 4 and the horizontally extending fish conveying pipeline 5 connected in an "L" shape. The fish conveying pipeline 5 is a straight pipeline, and the lifting pipeline 4 is connected to the internal channel of the fish conveying pipeline 5.
[0042] The top of the fish transport pipe 5 is provided with a water inlet 6. Seawater can be introduced into the fish transport pipe 5 through a water pipe connected to the water inlet 6 and a water pump placed on the hull 1.
[0043] The lifting pipe 4 is equipped with a lifting device that extends downward to the bottom of the cabin. The lifting device lifts the fish in the cabin to the top and transports them from the fish transport pipe 5 to the fish receiving bucket 2.
[0044] The lifting device includes a lifting chain 7 installed inside the lifting pipe 4, which is driven by a lifting motor 8 at the top; several fish lifting plates 9 are installed at intervals on the lifting chain 7.
[0045] Two extension plates 10 are connected and installed at the bottom of the lifting pipe 4. Two rotating shafts 21 are installed at the top of the lifting pipe 4 and on the extension plates 10. Each rotating shaft 21 is equipped with a lifting gear 11. The lifting gear 11 meshes with the inner side of the lifting chain 7. The lifting chain 7 is driven to rotate by the lifting motor 8, the rotating shaft 21, and the lifting gear 11.
[0046] Each fish-lifting plate 9 has a fish-lifting cavity 12, and the side wall of the fish-lifting plate 9 closest to the conveying pipe is an open structure. During operation, the open side of the fish-lifting plate 9 is close to the inner wall of the conveying pipe.
[0047] The bottom of the fish lifting chamber 12 has a slight sloping trend, which is downward towards the side closer to the fish conveying pipe 5, and gradually becomes flat at the end.
[0048] The lifting device also includes a baffle 13 that is rotatably installed on the top of the lifting pipe 4. The baffle 13 is vertically positioned at the turning point of the lifting chain 7. When the fish lifting plate 9 reaches the top and begins to tilt, the baffle 13 is used to guide all the fish into the inlet of the fish conveying pipe 5.
[0049] The lifting device also includes two airbags 14 spaced apart on the top of the fish transport pipe 5. The two airbags 14 are sealed on the outer and inner pipes of the fish transport pipe 5 respectively through a three-way base 15 and a double-way base 16. The airbags 14 deliver gas through an air pipe 17 extending to the hull 1, and adjacent airbags 14 are connected by an air pipe 18.
[0050] Before starting work, the boat 1 is brought ashore. The drive motor 20 and drive gear 19 are used to rotate the conveying pipe so that the outlet of the fish conveying pipe 5 is connected to the fish receiving bucket 2. At this time, the conveying pipe is perpendicular to the boat 1. The staff on the boat use a pre-placed air pump to deliver hydrogen or helium into the air bag 14 and adjust the angle of the fish conveying pipe 5 so that it tilts slightly downward.
[0051] On board, staff used water pumps and pipes to pump nearby seawater from inlet 6 into fish transport pipe 5, continuously flushing the pipe.
[0052] During transport, the lifting motor 8 drives the lifting chain 7 to rotate counterclockwise continuously. As the lifting chain 7 rotates, the fish lifting plate 9 stores the fish and seawater stored in the hold in the fish lifting chamber 12 at the same time. The fish lifting plate 9 lifts the fish upwards. When the fish lifting plate 9 moves to the top, it will gradually tilt. With the help of the baffle 13, it can ensure that the fish poured out can smoothly enter the fish transport pipe 5. With the seawater constantly flushing the fish transport pipe 5, the fish in the pipe will not be stuck in the fish transport pipe 5.
[0053] After the work is completed, the motor on the control hull 1 can be reversed to restore the delivery pipe to a parallel state with the hull 1, and the gas in the airbag 14 can be released, allowing normal navigation.
