Description

Technical Field

[0001] The invention relates to the technical field of grouper breeding, and in particular to a device for keeping grouper alive during land and sea transportation. Background Art

[0002] Deep-sea cage farming of grouper is a farming model with high economic value. Its main operation method is to raise grouper fry on land to a certain size and then transfer them to deep-sea cages via land and sea. How to ensure the survival rate of live fish during land and sea transportation is a problem that needs to be solved. The survival rate not only refers to whether the grouper is alive after the transportation, but also needs to try to reduce the stress of the grouper during transportation.

[0003] To ensure the smooth transfer of live fish from land to the fish holds of live fish vessels, at least the following safeguards must be met. First, ensure adequate movement space for the fry during transport, ensuring they are not squeezed but can move freely. This also reduces the impact of surges during transport, thereby minimizing damage to the fish. Second, maintain sufficient dissolved oxygen in the water. Third, maintain relative stability during the loading and unloading of grouper. Fourth, after the live fish transporter arrives at the dock, slowly inject seawater into the breeding container to allow the grouper to gradually acclimate to the seawater temperature and water quality.

[0004] In order to meet the above-mentioned land-sea transportation needs of grouper, it is necessary to design a land-sea transportation device for grouper according to the needs to ensure the survival rate of grouper during the land-sea transportation process. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for keeping grouper alive during land-sea transport, so as to solve the problems described in the background technology.

[0006] The technical solution of the present invention is achieved as follows:

[0007] The invention relates to a device for keeping grouper alive during land and sea transportation, comprising a carriage and a transit circulation oxygenation component arranged in the carriage, and further comprising a plurality of slide rails and a plurality of water pipe brackets arranged in the carriage, the slide rails extending in the front-rear direction of the carriage, a fish carrying component being fixedly and detachably slidably connected to the slide rails, a water supply pipe and a return pipe being provided on the water pipe brackets, a plurality of branch pipes being provided on the water supply pipes, a flow valve being provided on the branch pipes of the water supply pipes, the water supply pipes and the return pipes being connected to the transit circulation oxygenation component, the fish carrying component comprising a bottom plate fixedly and detachably slidably connected to the slide rails, two square pipes extending in the front-rear direction and parallel to each other being provided at the lower end of the bottom plate, a rectangular placement frame being provided at the upper end of the bottom plate, a plurality of water tank groups being provided in the rectangular placement frame, a restriction cage being further provided at the upper end of the bottom plate for covering and fixing the plurality of water tank groups, the water tank group comprising a bottom box, a middle box, a top box and a box cover stacked in sequence from bottom to top;

[0008] The bottom box, middle box and top box all include a rectangular box body with an open upper end, the interior of the box body is provided with at least three spaced-apart perforated partitions, the bottoms of the perforated partitions are fixedly mounted on the inner bottom wall of the box body, thereby dividing the interior of the box body into multiple fish storage compartments, the tops of the side walls of the box body are also jointly upwardly provided with flanges, thereby surrounding and connecting to form an inner convex ring, the top of the inner convex ring is downwardly provided with an annular groove, the annular groove is provided with an elastic sealing ring with the top higher than the annular groove, the bottom of the box body also protrudes downwardly to form an outer convex ring, the box bodies of the top box and the middle box are also fixed with an overflow pipe that penetrates the bottom of the box body, the middle and upper ends of the side walls of the top box are also penetrated with a top water inlet pipe, the middle and upper ends of the side walls of the bottom box are also penetrated with a bottom drainage pipe, the top water inlet pipe is connected to the branch pipe of the water supply pipe, and the bottom drainage pipe is connected to the branch pipe of the return pipe;

[0009] When the two boxes are stacked up and down, the outer convex ring of the upper box is sleeved on the outer convex ring of the lower box, the outer wall of the inner convex ring slides and fits with the inner wall of the outer convex ring, the bottom of the upper box presses the sealing ring of the lower box, and the box cover is arranged on the top of the top box. Under the action of the restriction cage, the bottom of the box cover and the sealing ring of the top box are sealed;

[0010] A plurality of water tank groups are arranged closely to form a rectangular stacking body, the top water inlet pipe and the bottom drainage pipe are both arranged on the side wall of the stacking body, and the bottom of the side wall of the stacking body is fitted against the inner wall of the rectangular placement frame.

[0011] When using this solution, before packing, aquaculture water is first poured into the box. Groupers are then placed into the fish compartments within the box, one grouper per compartment. The bottom box is then placed within a rectangular frame on the baseboard, filling the entire frame. The rectangular frame restricts movement of the bottom box on the baseboard. The middle boxes are then stacked one on top of the bottom boxes, followed by the top box on top of the middle box. The box lids are then installed, ensuring that the top water inlet pipe of the top box and the bottom drain pipe of the bottom box are placed on the same side. A restraining cage is then used to constrain the stack of boxes, confining them to the baseboard and preventing them from spreading due to the swaying of the vehicle during transportation. This also allows the box lids to remain firmly pressed against the top boxes.

[0012] By arranging the outer convex ring and the inner convex ring, the boxes are easier to position when stacked, and can also effectively prevent the boxes from falling out. The weight of the boxes themselves is used to compress the sealing ring to achieve the function of preventing water leakage.

[0013] Once the fish carrier is installed, a forklift is inserted through the square tubes and lifted into the transport vehicle's compartment, ensuring smooth loading and unloading. Once inside, the carrier is aligned with the slide rails, connecting them to the rails. The slide rails push the carrier to the bottom of the rails. After multiple carriers are loaded, they are secured to prevent them from sliding due to the vehicle's movement. Upon arrival at the port, the carrier can be smoothly removed using a forklift and transported the short distance to the live fish vessel. The stacked boxes can also be quickly removed and easily handled, facilitating the rapid loading and unloading of the grouper into the vessel's fish hold. The entire loading and unloading process remains relatively stable, minimizing stress for the grouper.

[0014] After all the fish-carrying parts are loaded, connect the branch pipe of the water supply pipe to the top water inlet pipe, connect the branch pipe of the return pipe to the bottom drainage pipe, and then start the transfer circulation oxygenation component.

[0015] Water is supplied to the water supply pipe through the transfer circulation aeration component. The water enters the top box after the flow rate is limited by the flow valve. After the water in the top box increases, it enters the lower middle box through the overflow pipe. Through the transmission of the overflow pipe, the water body is transferred to the bottom box, and flows into the return pipe through the bottom drainage pipe, and then flows back to the transfer circulation aeration component through the return pipe for water oxygenation. The oxygenated water body then enters the water tank group to increase the dissolved oxygen content in the water body of the tank body, so as to maintain sufficient dissolved oxygen content in the water body.

[0016] By installing perforated partitions, the box is divided into multiple fish compartments, allowing groupers to occupy separate spaces. The compartments not only provide the groupers with adequate room to move around, preventing them from being squeezed by other groupers in the box, but also reduce surge impact during transportation, thereby minimizing damage to the fish. The perforated partitions also facilitate water exchange within the box, ensuring fluidity.

[0017] After the transport vehicle is transported to the port, the seawater is introduced into the transit circulation oxygenation component and slowly injected. Through the overflow water exchange method of the water tank group, the seawater and the aquaculture water in the original tank are slowly replaced, which can effectively and slowly allow the grouper to adapt to the temperature and water quality of the seawater and reduce the stress of the grouper.

[0018] By using the above scheme, the survival rate of grouper during land-sea transportation can be effectively improved.

[0019] A further technical solution is that the transfer circulation oxygenation component includes a controller, a water level sensor, a drainage box, a first water pump, a transfer box, a second water pump and an air pump. The side wall of the drainage box is penetrated by a first water inlet pipe with the same number as the return water pipe. The height of the first water inlet pipe is lower than the height of the return water pipe. The bottom of the side wall of the drainage box is also penetrated by a first drain pipe. The first drain pipe is provided with a valve. The water inlet of the first water pump is connected to the bottom of the side wall of the drainage box through a first pumping pipe. The water outlet of the first water pump is connected to the top of the side wall of the transfer box through a first outlet pipe. The water level sensor is arranged inside the drainage box and is higher than the connection between the first pumping pipe and the drainage box. A partition is vertically provided in the transfer box to separate the interior of the transfer box into an aeration bin and an overflow bin. The partition The bottom and both sides are sealed with the inner wall of the transfer box respectively, and the top of the partition extends upward to the upper and middle end of the transfer box. An aeration component is provided at the bottom of the aeration bin, and the aeration component is connected to the air pump provided outside the transfer box. The water inlet of the second water pump is connected to the bottom of the side wall of the overflow bin through a second pumping pipe, and the water outlet of the second water pump is connected to a second water outlet pipe, and the second water outlet pipe is connected to a multi-way joint. The number of water outlet ends of the multi-way joint is the same as the number of water supply pipes, and the water supply pipe is connected to the water outlet end of the multi-way structure in a one-to-one correspondence. A second water inlet pipe and a drain pipe are also respectively penetrated at the upper and middle end of the side wall of the overflow bin, and valves are provided on the second water inlet pipe and the drain pipe. The water level sensor, the first water pump, the second water pump and the air pump are all electrically connected to the controller.

[0020] When using the above solution, first pour an appropriate amount of aquaculture water into the transfer tank, and then start the second water pump through the controller. The second water pump pumps out the aquaculture water in the overflow bin and inputs it into each water supply pipe through the multi-way joint. The water in the water tank group is finally discharged from the bottom drainage pipe of the bottom box through the overflow, and flows back to the drainage tank through the return pipe. When the water level sensor detects the water level information, the first water pump starts to pump the water in the drainage tank into the aeration bin. The air pump starts to aerate and oxygenate the water in the aeration bin through the aeration component. The oxygenated water overflows through the partition into the overflow bin for the second water pump to extract.

[0021] By setting up overflow tanks and aeration tanks, the water body can be adequately aerated before being extracted, ensuring the oxygenation effect of the water body.

[0022] When seawater needs to be replaced, the valve on the first drain pipe is opened, the first water pump is turned off, the second water inlet pipe is connected to the pump that extracts seawater, and the drain pipe is connected to the outside of the vehicle. The external seawater is pumped into the overflow tank, and the second water pump pumps the seawater into the water tank assembly to replace the aquaculture water. The water discharged from the aquaculture water enters the drain tank and is discharged through the first drain pipe. The installation of the drain pipe effectively prevents the excessive input of seawater and acts as a drainage device.

[0023] A further technical solution is that when two adjacent upper and lower boxes with overflow pipes are stacked, the positions of the two overflow pipes are set opposite to each other. When the number of boxes in the water tank group is odd, an extension pipe is also provided in the box body of the bottom box, one end of the extension pipe is connected to the bottom drainage pipe, and the other end of the extension pipe extends in a direction away from the bottom drainage pipe to the middle and rear end of the box.

[0024] When using the above solution, the overflow pipes arranged in opposite directions can fully exchange the water in the box. By arranging the extension pipe, the water in the bottom box can be fully exchanged when the number of boxes is an odd number.

[0025] A further technical solution is that the water pipe bracket includes two vertical rods arranged at intervals, which are fixed to the bottom of the carriage. Two horizontal rods are respectively connected between the two vertical rods. The two horizontal rods are arranged at intervals up and down. The water supply pipe is fixed on the upper horizontal rod, and the return pipe is fixed on the lower horizontal rod. The height of the return pipe is not higher than the height of the bottom drainage pipe.

[0026] A further technical solution is that each set of slide rails includes two wheel rails with a 'U'-shaped cross-section, the two wheel rails are arranged parallel to each other and spaced apart, four wheels are fixed to the bottom of the base plate, the four wheels are arranged at the four corners of a virtual rectangle, the four wheels are respectively connected in pairs to the two wheel rails of each set of slide rails in a rolling manner, and the wheel rails are detachably clamped with a positioning clamp, each set of water pipe brackets includes two water pipe brackets, the two water pipe brackets in each group are respectively arranged on both sides of the two wheel rails of each group, and the positioning clamps are used to support the base plate.

[0027] When using this solution, the U-shaped track effectively complements the wheel, providing both guidance and restraint. After loading, multiple fish carriers are secured together by the counter-attachment of the bottom plates. Finally, positioning clamps at both ends of the track provide a clamping force, making installation and removal easy.

[0028] A further technical solution is that the positioning clamp includes an inverted 'U' shaped clamping block, a side wall of the clamping block is threaded with a third bolt, and after the clamping block is embedded in the wheel rail, it is tightened against the wheel rail by the third bolt.

[0029] When using the above solution, after the 'U'-shaped clamping block is embedded in the wheel rail, it is clamped by tightening the third bolt.

[0030] A further technical solution is that the restriction cage includes four rectangular guardrail frames, the bottoms of the four rectangular guardrail frames are hinged to the upper end surface of the base plate by hinges, and the four rectangular guardrail frames together form a rectangular cage body. The two adjacent rectangular guardrail frames are detachably fixedly connected by connecting parts, the side walls of the stacking body are fitted against the rectangular guardrail frames, and the top of the cage body is also detachably installed with a pressure rod that can be adjusted up and down, and the box cover on the top of the stacking body is against the pressure rod.

[0031] When using the above solution, after the stacked body is placed, the four rectangular guardrail frames are combined and fixed with connectors to effectively restrict the box body and prevent it from moving. The box cover is pressed tightly by the pressure rod to complete the sealing of the top box.

[0032] A further technical solution is that a plug ring is provided on the top of the rectangular guardrail frame, and the pressure rod is slidably inserted into the plug rings of the rectangular guardrail frame on two opposite sides. The top of the rectangular guardrail frame is also screwed downward with a first bolt, and the bottom of the first bolt is against the top of the pressure rod.

[0033] When using the above solution, after the pressure rod is passed through the two inserting rings, the first bolt is screwed downward, and the first bolt applies force to the pressure rod downward, so that the pressure rod presses the box cover tightly.

[0034] A further technical solution is that quick connectors are provided on the pipe openings of the top water inlet pipe and the bottom drainage pipe.

[0035] When using the above solution, the quick connector facilitates connection.

[0036] A further technical solution is that the plurality of fish storage bins are rectangular parallelepiped bins arranged side by side.

[0037] The beneficial effects of the present invention are:

[0038] 1. Reasonable box design: Stable stacking: The outer and inner convex rings ensure stable stacking and prevent the boxes from falling out. A restraining cage restrains the stacked items to prevent them from spreading during transport and ensures the box lid is tightly pressed. Leak-proof and sealed: The weight of the box compresses the sealing ring to prevent water leaks. Partitioned and damage-resistant: Perforated partitions separate the box into multiple fish compartments, providing appropriate space for grouper to move around and avoid squeezing each other, reducing surge impact and minimizing fish damage. It also facilitates water exchange and ensures water flow.

[0039] 2. Convenient loading and unloading: Smooth loading and unloading: After the fish-carrying components are installed, they are lifted by a forklift through the square tubes for smooth loading and unloading. Secure and secure: After entering the carriage, the fish-carrying components connect to the slide rails and can be pushed to the bottom. After loading multiple components, they are secured to prevent sliding during operation. Efficient unloading and loading: Upon arrival at the port, the fish-carrying components are smoothly removed by forklift and transported over short distances to the live fish vessel. Stacking the containers allows for quick removal and handling, facilitating the rapid introduction of grouper into the live fish vessel's fish hold. The entire loading and unloading process is stable, reducing stress on the grouper.

[0040] 3. Improved water circulation system: Circulating oxygenation: The transit circulating oxygenation component forms a circulation through the water supply pipe, top water pipe, overflow pipe, bottom drainage pipe and return pipe to oxygenate the water in the box and maintain sufficient dissolved oxygen.

[0041] 4. Water quality replacement: After being transported to the port, seawater can be slowly introduced into the transit circulation oxygenation component. Through the overflow water exchange method of the water tank group, the seawater and the original breeding water are slowly replaced, allowing the grouper to adapt to the seawater temperature and water quality and reduce stress.

[0042] 5. Scientific water treatment process: Aeration and oxygenation: Set up overflow tank and aeration tank, the second water pump draws aquaculture water from the overflow tank to the water supply pipe, the water in the water tank group is discharged from the bottom drain pipe and returned to the drainage tank through the return pipe. After the water level sensor detects the water level, the first water pump draws the drainage tank water into the aeration tank, and the air pump adds oxygen through the aeration component. After oxygenation, the water overflows to the overflow tank for the second water pump to draw, ensuring the oxygenation effect of the water body.

[0043] 6. Controllable seawater replacement: When replacing seawater, open the first drain pipe valve, close the first water pump, connect the second water inlet pipe and the drain pipe, pump the external seawater into the overflow tank, and the second water pump pumps the seawater out to the water tank group to replace the aquaculture water. The water discharged from the drainage tank is discharged through the first drain pipe. The drain pipe can prevent the seawater from being input too quickly and play a role in drainage.

[0044] 7. Sufficient water exchange: Overflow pipes arranged in opposite directions allow sufficient water exchange in the box. Extension pipes can be set to allow sufficient water exchange in the bottom box when the number of boxes is odd. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the selection and installation of wheels are technical means that are already proficient in the prior art. Therefore, the connection structure diagram between the wheels and the base plate 29 is not provided in the accompanying drawings. However, this should not constitute insufficient disclosure of the technical solution. Those skilled in the art can fully realize the installation of the wheels and the base plate 29 based on the existing technology and the description of this disclosure.
