Description

Technical Field

[0001] This utility model relates to the field of aquaculture vessels, and more particularly to a water quality control device for a sea-accessible aquaculture vessel. Background Technology

[0002] Aquaculture vessels are a new type of fishery platform that utilizes marine engineering equipment and aquaculture technology to carry out industrialized and large-scale fishery production in deep seas.

[0003] In related technologies, such as Chinese Patent No. CN217717714U, a water quality control system for the fish hold of an aquaculture vessel is disclosed, which includes a host computer, a switch, a signal acquisition box, multiple water quality monitoring sensors, a seawater exchange pump, a seawater exchange frequency converter, and an oxygen supply device.

[0004] Regarding the aforementioned technologies, the inventors believe that as the breeding time increases, the water quality deteriorates due to the continuous accumulation of organic matter such as fish excrement and leftover feed in the breeding tank. The method of emptying the seawater in the breeding tank and then refilling it takes too long and requires the fish to be removed in advance, which is too inefficient. Utility Model Content

[0005] In order to improve the efficiency of water exchange in the cabin, this utility model provides a water quality control device for a sea-access aquaculture vessel.

[0006] This utility model provides a water quality control device for a sea-access aquaculture vessel, which adopts the following technical solution: A water quality control device for a sea-access aquaculture vessel includes a pumping pipe for pumping water, a filter screen for filtering impurities in the water, a locking device for locking the filter screen, and an isolation cover fitted onto the pumping pipe for isolating fish. A fixing pipe is embedded in the inner wall of the pumping pipe, and the fixing pipe is fitted to the inner wall of the pumping pipe. The filter screen is fixedly connected to the fixing pipe, and the locking device fixes the fixing pipe in the pumping pipe.

[0007] By adopting the above technical solution, water is pumped out of the aquaculture vessel through a water pumping pipe and filtered through a filter screen. The filtered water is then transported back into the aquaculture vessel for reuse, thereby controlling the water quality of the aquaculture vessel and realizing internal circulation and purification of the water body. In addition, the isolation cover can prevent fish from being sucked into the water pumping pipe.

[0008] Optionally, the locking device includes a locking block for locking the fixed pipe, an operating rod for operating the locking block, and a limiting rod for limiting the locking block; the locking block is slidably connected to the water pipe and passes through the fixed pipe, the operating rod is fixedly connected to the locking block and one end of the operating rod extends out of the water pipe, and the limiting rod is fixedly connected inside the water pipe. When the locking block locks the fixed pipe, one end of the locking block abuts against the limiting rod.

[0009] By adopting the above technical solution, when it is necessary to use a water pumping pipe for water pumping, the fixed pipe is embedded in the water pumping pipe and the locking block passes through the fixed pipe and abuts against the limiting rod, thereby completing the quick locking of the fixed pipe, so that the filter screen remains stable when subjected to water flow impact, ensuring the stability and reliability of the filtration process.

[0010] Optionally, the locking device further includes a sliding rod and a first compression spring located between the limiting rod and the locking block. One end of the sliding rod is hinged to the limiting rod, and the other end of the sliding rod is slidably connected to the locking block. The first compression spring drives the locking block and the operating rod to slide away from the limiting rod. When the sliding rod slides to the end of the locking block near the operating rod, the locking block locks the fixed tube. When the sliding rod slides to the end of the locking block away from the operating rod, the locking block releases the lock on the fixed tube.

[0011] By adopting the above technical solution, the sliding rod slides to different positions within the locking block to switch whether the locking block locks the fixed pipe, and the self-locking function is achieved through the restoring force of the first compression spring, preventing accidental release of the lock due to water flow vibration or pressure, thus enhancing safety.

[0012] Optionally, a hinge post is provided between the sliding rod and the limiting rod, and the hinge post and the sliding rod are hinged; a sliding post is provided between the locking block and the sliding rod, the sliding post and the locking block are slidably connected, and the locking block has a sliding groove for the sliding post to slide in.

[0013] By adopting the above technical solution, the hinged column ensures that the sliding rod can rotate smoothly around the limiting rod. The cooperation between the sliding column and the sliding groove provides the sliding rod with a precise movement trajectory, ensuring the stability of the locking block during linear movement and making the entire locking and unlocking action more stable.

[0014] Optionally, a rubber sleeve is fitted on the operating rod, and a fixing plate is fixedly connected to one end of the rubber sleeve. The fixing plate is threadedly connected to the outer wall of the water pumping pipe.

[0015] By adopting the above technical solution, the rubber sleeve is tightly fitted onto the part of the operating rod that protrudes from the water pumping pipe, forming an effective waterproof sealing layer that can prevent external water from seeping into the equipment through the gap between the operating rod and the water pumping pipe wall.

[0016] Optionally, a locking ring is provided on the water pumping pipe. When the isolation cover is fitted onto the water pumping pipe, the locking ring passes through the isolation cover to lock it.

[0017] By adopting the above technical solution, the locking ring provides a reliable fixing point for the isolation cover, ensuring that the isolation cover can be stably installed on the water pipe and will not shift or fall off due to water flow or fish impact, thus guaranteeing its effectiveness in isolating fish.

[0018] Optionally, the isolation cover is provided with a locking rod that passes through the locking ring. One end of the locking rod that passes through the isolation cover is provided with a limiting piece. The locking ring is provided with a groove for the limiting piece to be inserted. When the limiting piece passes through the locking ring, the locking rod is rotated to insert the limiting piece into the groove.

[0019] By adopting the above technical solution, when installing the isolation cover, simply align the limiting piece at the end of the locking rod with the hole of the locking ring and insert it, then rotate it at a certain angle so that the limiting piece is locked into the groove to complete the fixation. The operation is very simple and quick, making it convenient for the installation and disassembly of the isolation cover.

[0020] Optionally, a pressing piece is provided at one end of the locking rod extending out of the isolation cover, and a second compression spring is sleeved on the locking rod, with the isolation cover and the pressing piece respectively fixedly connected at both ends of the second compression spring.

[0021] By adopting the above technical solution, the elastic force of the second compression spring continuously acts on the pressing plate, thereby maintaining the tight fit between the limiting plate and the groove, avoiding self-loosening due to vibration. When disassembly is required, pressing the pressing plate overcomes the spring force, and the locking rod can be easily rotated to unlock.

[0022] Optionally, a rubber ring is provided on the outer wall of the water pumping pipe, and a sealing groove is provided on the isolation cover for the rubber ring to be embedded.

[0023] By adopting the above technical solution, the rubber ring and the sealing groove form a sealing structure, which can effectively prevent water from leaking from the gap between the isolation cover and the water pumping pipe, ensuring that all water to be treated must be filtered through the filter screen, thereby improving the water treatment effect and the working efficiency of the equipment.

[0024] Optionally, the isolation cover is provided with a number of isolation rods for isolating fish and supplying water inflow, and an isolation ball is provided at the end of the isolation rod away from the filter screen.

[0025] By adopting the above technical solution, the isolation bar forms a grid that allows water to flow through, while effectively preventing fish from approaching the water inlet. The isolation ball on the isolation bar can prevent fish from being sucked onto the grid by the water inlet pipe and causing obstruction.

[0026] In summary, this utility model has at least one of the following beneficial technical effects: Through the combined design of pumping pipes, fixed pipes and filter screens, the water in the aquaculture boat's cabin is efficiently circulated, filtered and reused, greatly improving water exchange efficiency and water resource utilization. By designing a locking device with a self-locking function, the installation stability of the filter screen is ensured under the impact of high-speed water flow, and it is easy to install and remove, and convenient for maintenance and cleaning. The design of the isolation cover effectively prevents fish from being sucked in while ensuring normal water flow, thus improving safety. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This utility model discloses a water quality control device for a sea-access aquaculture vessel.

[0031] Reference Figure 1 and Figure 2A water quality control device for a sea-going aquaculture vessel includes a water pumping pipe 1, a filter screen 2 installed in the water pumping pipe 1, a locking device 3 for locking the filter screen 2, and an isolation cover 4. The water pumping pipe 1 is placed inside the hull 5 to pump water out of the hull 5, filters out impurities using the filter screen 2, and then recirculates the filtered water back into the hull 5. A water pump connected to the water pumping pipe 1 pumps water out of the hull 5 and stores it in a bucket outside the hull 5, then pours the water from the bucket back into the hull 5. The isolation cover 4 is fitted over the water pumping pipe 1 to prevent fish from being sucked into the water pumping pipe 1.

[0032] Reference Figure 1 and Figure 2 An isolation rod 41 is installed at one end of the isolation cover 4, and an isolation ball 42 is installed at the end of the isolation rod 41 away from the filter screen 2. The isolation cover 4, the isolation rod 41, and the isolation ball 42 are integrally injection molded. The isolation balls 42 are evenly distributed on the isolation rod 41. When the water pumping pipe 1 starts pumping water, the isolation rod 41 and the isolation ball 42 can cooperate with each other to prevent fish from being sucked into the water pumping pipe 1, while allowing water to flow normally.

[0033] Reference Figure 1 and Figure 2 The filter screen 2 is ultrasonically welded to the fixed pipe 11. The fixed pipe 11 has a clearance groove 112 for the clearance locking device 3. When the water pumping pipe 1 is needed, the filter screen 2 can be installed by embedding the fixed pipe 11 into the water pumping pipe 1 so that the water can be filtered by the filter screen 2 when it is pumped into the water pumping pipe 1.

[0034] Reference Figure 3 and Figure 4 The locking device 3 includes a locking block 31, an operating rod 32, a limiting rod 33, a sliding rod 34, and a first compression spring 35. The limiting rod 33 is fixedly welded to the inner wall of the pumping pipe 1. A sliding hole is opened in the pumping pipe 1 for the locking block 31 and the operating rod 32 to slide. The operating rod 32 is welded to one end of the locking block 31 to control the sliding of the locking block 31. A through hole 111 is opened on the fixed pipe 11 for the locking block 31 to pass through. When the operating rod 32 is controlled to slide the locking block 31 into the through hole 111, the locking block 31 locks the fixed pipe 11.

[0035] Reference Figure 3 and Figure 4The locking block 31 has a sliding groove 311, and a sliding column 342 is slidably connected within the sliding groove 311. The sliding column 342 is welded to the sliding rod 34. A hinge column 341 is welded to the limiting rod 33, and the hinge column 341 is hinged to the sliding rod 34. A first compression spring 35 is welded between the locking block 31 and the limiting rod 33 and always drives the locking block 31 to move away from the limiting rod 33. The sliding groove 311 includes a locking part 312, an unlocking part 313, and a sliding part 314. When the water pipe 1 and the filter screen 2 need to be used, the sliding column 342 is slid into the locking part 312 within the sliding groove 311 by pressing the operating rod 32, thereby locking the fixed pipe 11 and ensuring that the filter screen 2 works normally in the water pipe 1 without loosening. When the filter screen 2 needs to be disassembled for cleaning or maintenance, the sliding column 342 can be moved in the sliding groove 311 to the unlocking part 313 by pressing the operating lever 32, thereby unlocking the fixed pipe 11 and removing the fixed pipe 11 from the water pipe 1.

[0036] Reference Figure 3 and Figure 4 The operating lever 32 is fitted with a rubber sleeve 321, and a fixing piece 322 is integrally provided at the end of the rubber sleeve 321 near the water pumping pipe 1. A threaded groove is opened on the water pumping pipe 1, and the fixing piece 322 is threadedly connected to the threaded groove, so that the water in the cabin 5 will not seep into the water pumping pipe 1 through the locking device 3, so as to ensure that the water recycled in the water pumping pipe 1 is filtered water.

[0037] Reference Figure 4 and Figure 5 A locking ring 12 is welded onto the water pump pipe 1. When the isolation cover 4 is fitted onto the water pump pipe 1, the locking ring 12 is embedded into the isolation cover 4. A second compression spring 46 is welded onto the outer wall of the isolation cover 4. A pressing plate 45 is welded to one end of the second compression spring 46. A locking rod 43 is welded to the end of the pressing plate 45 near the isolation cover 4. A limit plate 44 is integrally provided at the end of the locking rod 43 away from the pressing plate 45.

[0038] Reference Figure 4 and Figure 5 Both the isolation cover 4 and the locking ring 12 have through holes 48 for the locking rod 43 to slide. The isolation cover 4 also has a rotating groove 49 for the limiting piece 44 to pass through and rotate. The locking ring 12 also has a groove 121 for the limiting piece 44 to be embedded at the end away from the pressing piece 45. When the isolation cover 4 is fitted onto the water pipe 1, the locking rod 43 can be passed through the isolation cover 4 and the locking ring 12 in sequence and enter the rotating groove 49 by pressing the pressing piece 45. After the pressing piece 45 is rotated and released, the limiting piece 44 will automatically embed into the groove 121 under the action of the second compression spring 46, thereby completing the locking between the isolation cover 4 and the locking ring 12.

[0039] Reference Figure 4 and Figure 5A rubber ring 13 is welded onto the water pump pipe 1, and a sealing groove 47 is opened on the isolation cover 4 for the rubber ring 13 to be inserted. When the isolation cover 4 is fitted onto the water pump pipe 1, the rubber ring 13 is inserted into the sealing groove 47 to seal the isolation cover 4 and prevent the infiltration of unfiltered water.

[0040] The implementation principle of the water quality control equipment for a sea-crossing aquaculture vessel according to this utility model embodiment is as follows: a fixed pipe 11 with a filter screen 2 is embedded into a water pumping pipe 1 and locked by a locking device 3. The water pumping pipe 1 draws water from the cabin 5 into the water pumping pipe 1, while the fish are isolated outside by an isolation cover 4. After the water flows into the water pumping pipe 1, it is filtered by the filter screen 2, and solid impurities are removed. The filtered water is reused and flows back into the cabin 5, thereby achieving efficient internal circulation and purification of the water.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
