Abstract
Description
Technical Field
[0001] This utility model relates to the fields of aquaculture and marine engineering, specifically proposing a special device for drawing seawater from the deep sea for use on aquaculture vessels. Background Technology
[0002] With the continuous development of large-scale deep-sea aquaculture facilities technology, especially with the increasing application of aquaculture workboats in the deep-sea aquaculture industry, the industry is showing multiple development directions, such as optimizing ship design, increasing the volume of aquaculture water on workboats, improving automation and aquaculture efficiency, and reducing aquaculture costs.
[0003] Existing deep-sea aquaculture vessels typically employ a closed-hull structure. Water is drawn into the hull through an inlet at the bottom, then pumped into the hull before being supplied to the various aquaculture tanks. Since cold-water fish farming requires water from deeper waters, one or more pipes need to be extended 30-40 meters below sea level. This places high technical standards on the efficiency of lowering and retrieving these pipes from the hull, including requirements for convenient and quick deployment and retrieval, ensuring the pipes do not extend beyond the ship's side during navigation, and ensuring efficient, economical, and durable operations. Currently, the equipment configuration of aquaculture vessels has not effectively addressed these issues.
[0004] In view of the above, this patent application is hereby filed. Utility Model Content
[0005] The water intake device on the hull of the aquaculture vessel described in this utility model aims to solve the problems existing in the prior art by proposing a dedicated water intake mechanism on the side of the hull based on the water pump system of the aquaculture vessel. This enables timely water intake and release operations, allowing the water to be fully retracted inside the hull and above the deck during navigation, and to be completely lowered when deep seawater needs to be drawn.
[0006] To achieve the above design objectives, the aquaculture vessel's side water intake device includes a bracket installed on the deck, with two sets of rotating arms movably connected to the bracket and a set of water inlet pipes connected to the side water inlet. The two sets of rotating arms are respectively driven and connected to a first lifting plate and a second lifting plate. A sliding sleeve is suspended and connected to the first lifting plate. A lifting mechanism for raising and lowering the water inlet pipe is provided between the first lifting plate, the second lifting plate and the bracket.
[0007] Furthermore, several slipways are provided on the hull of the aquaculture vessel, and a hull water inlet is provided at the vertical bottom of each slipway; the slipway has a concave annular groove with a semi-circular bottom; the hull water inlet is connected to the vessel's water pump system to draw water from the external sea area into the interior of each cabin.
[0008] Furthermore, the bracket includes a first mounting base and a second mounting base for connecting the two sets of rotating arms, and a third hole.
[0009] Furthermore, the first lifting plate includes a first plate, on which several pairs of first pins for axially connecting the rotating arm are provided, several fourth holes are provided, and two sets of concave sliding grooves are provided vertically at the bottom of the first plate, with a first pin horizontally provided in at least one set of sliding grooves.
[0010] Furthermore, the second lifting plate includes a second plate, on which several pairs of second pins for axially connecting the rotating arm and a fifth hole are provided.
[0011] Furthermore, the sliding sleeve includes a sliding sleeve body with a hollow cylindrical structure, and a vertically distributed sliding plate is fixedly connected to the water inlet formed by the opening at the side end of the sliding sleeve body. An annular sealing groove is provided on the outside of the water inlet. An array of first pull cables is suspended at the top of the sliding sleeve body and the sliding plate. The sliding plate can be inserted into the sliding groove and slide back and forth vertically.
[0012] Furthermore, the swing arm includes several pairs of bent rods, the bottom of each bent rod being hinged to the bracket and its top being hinged to the first or second lifting plate.
[0013] Furthermore, the water inlet pipe has a rotating ring fixedly connected to its inner end opening via a bent flange, and the pressure plate is fixedly connected to the sliding sleeve from one side via bolts. The rotating ring is clamped between the pressure plate and the sliding sleeve and can rotate axially. The airbag is nested and connected inside the sealing groove.
[0014] Furthermore, the hoisting mechanism includes at least one first electric hoist fixedly installed on the first hoisting plate and at least one second electric hoist installed on the second hoisting plate. Multiple sets of first cables of the sliding sleeve are wound around the first electric hoist through the fourth hole. One end of at least one set of second cables is suspended from the water inlet pipe through a cable fixing ring fixedly sleeved on the water inlet pipe, and the other end is wound around the second electric hoist through the fifth hole of the second hoisting plate.
[0015] Furthermore, the two sets of rotating arms are connected to the pick-and-place transmission mechanism, which includes a third pin fixedly connected to one set of rotating arms and a fourth pin fixedly connected to the other set of rotating arms. A first hydraulic cylinder is mounted on a bracket on one side of the third pin, and its output end is hinged to the third pin through a first piston.

[0036] Example 1, such as Figure 1 As shown in the figure, a water intake device for the side of a deep-sea aquaculture vessel is designed to provide water for aquaculture of various types of fish in the deep-sea environment, making full use of the natural wild water environment of the deep sea to carry out the entire aquaculture process from fry to harvest.
[0037] Several slipways 103 and a set of aquaculture vessel side water intake devices are provided on the hull 102 of the aquaculture vessel 100. Each slipway 103 has a hull water inlet 104 at its vertical bottom, which is usually located below sea level. The slipway 103 has a concave annular groove with a semi-circular bottom. Therefore, a flat plate component fitted into the groove can only slide in from its top opening and slide back and forth along the vertical direction of the slipway 103, but cannot be dislodged from it. The hull water inlet 104 is connected to the vessel's water intake pump system to draw water from the external sea area into the various cabins.
[0038] Each set of aquaculture boats' side water intake devices includes a bracket 120 installed on the deck 101. Two sets of swing arms 160 and a set of water inlet pipes 170 connected to the side water inlet 104 are movably connected to the bracket 120. The two sets of swing arms 160 are respectively driven and connected to a first lifting plate 130 and a second lifting plate 150. A sliding sleeve 140 is suspended and connected on the first lifting plate 130. A lifting mechanism for raising and lowering the water inlet pipe 170 is provided between the first lifting plate 130, the second lifting plate 150 and the bracket 120.
[0039] The bracket 120 includes a first mounting base 121 and a second mounting base 122 for connecting two sets of rotating arms 160, and a third hole 123 for hinged steering transmission mechanism.
[0040] The first lifting plate 130 includes a first plate 131, on which several pairs of first pins 132 for axially connecting the rotating arm 160 are provided, several fourth holes 133, and two sets of concave sliding grooves 134 are vertically provided at the bottom of the first plate 131, in which a first pin 132 is horizontally provided.
[0041] The second lifting plate 150 includes a second plate 151, on which several pairs of second pins 152 for axially connecting the rotating arm 160 and a fifth hole 153 are provided.
[0042] The sliding sleeve 140 includes a hollow cylindrical sliding sleeve body 141. A vertically distributed sliding plate 142 is fixedly connected to the water inlet 143 formed by the opening at the side end of the sliding sleeve body 141. An annular sealing groove 144 is provided on the outside of the water inlet 143. An array of first pull cables 145 are suspended on the top of the sliding sleeve body 141 and the sliding plate 142. The sliding plate 142 can be inserted into the sliding groove 134 and slide back and forth vertically.
[0043] The swing arm 160 includes several pairs of bent rods, the bottom of each bent rod is hinged to the bracket 120 (specifically the first mounting seat 121 and the second mounting seat 122), and its top is hinged to the first lifting plate 130 (specifically the first pin 132) or the second lifting plate 150 (specifically the second pin 152).
[0044] The water inlet pipe 170 has a rotating ring 171 fixedly connected to its inner end opening via a bent flange. The pressure plate 172 is fixedly connected to the sliding sleeve 140 (specifically the sliding sleeve body 141) from one side via bolts. The rotating ring 171 is clamped between the pressure plate 172 and the sliding sleeve 140 and can rotate axially. The airbag 173 is nested inside the sealing groove 144. When the airbag 173 is inflated, it can make the water inlet 143 of the sliding sleeve 140 and the water inlet 104 on the ship's side airtight. When the airbag 173 is deflated, the water inlet 143 and the water inlet 104 on the ship's side loosen and release the airtightness.
[0045] The hoisting mechanism includes at least one first electric hoist 161 fixedly installed on the first hoisting plate 130 (specifically the first plate 131) and at least one second electric hoist 162 installed on the second hoisting plate 150 (specifically the second plate 151). Multiple sets of first cables 145 of the sliding sleeve 140 are wound around the first electric hoist 161 through the fourth hole 133. One end of at least one set of second cables 146 is suspended from the water inlet pipe 170 through a cable fixing ring 147 fixedly sleeved on the water inlet pipe 170, and the other end is wound around the second electric hoist 162 through the fifth hole 153 of the second hoisting plate 150.
[0046] To enable the two sets of rotating arms 160 to perform pick-up and drop-off operations, the two sets of rotating arms 160 can be connected to a pick-up and drop-off transmission mechanism. This pick-up and drop-off transmission mechanism includes a third pin 184 fixedly connected to one set of rotating arms 160 and a fourth pin 185 fixedly connected to the other set of rotating arms 160. A first hydraulic cylinder 180 is mounted on a bracket 120 on one side of the third pin 184, and its output end is hinged to the third pin 183 via a first piston 181. Driven by the first hydraulic cylinder 180, the first piston 181 moves and drives the first lifting plate 130 to move horizontally via the rotating arms 160.
[0047] The second hydraulic cylinder 182 is mounted on the bracket 120 on one side of the fourth pin 185, and its output end is hinged to the fourth pin 184 via the second piston 183. Driven by the second hydraulic cylinder 182, the second piston 183 moves and drives the second lifting plate 150 to move horizontally via the rotating arm 160.
[0048] Based on the structural design of the above-mentioned water intake device on the side of the aquaculture vessel, it is possible to achieve the following for the water intake and release operations:
[0049] 1) Collapsed state;
[0050] The first electric hoist 161 and the second electric hoist 162 respectively hoist the sliding sleeve 140 and the water inlet pipe 170 to the deck 101 of the aquaculture vessel 100. The sliding plate 142 fits into the sliding groove 134 to increase stability. The first hydraulic cylinder 180 and the second hydraulic cylinder 182 actuate to move both sets of rotating arms 160 to the centerline of the vessel. Figure 1 In the Y direction, all mechanisms of the water intake device are located inside the hull 102, which complies with shipbuilding industry regulations.
[0051] 2) Half-lowered state;
[0052] The action of the first hydraulic cylinder 180 and the second hydraulic cylinder 182 causes both sets of rotating arms 160 to move to the center line of the boat. Figure 1In the opposite direction of the Y direction, the first electric hoist 161 and the second electric hoist 162 respectively lift the sliding sleeve 140 and the water inlet pipe 170 and move them downward until the sliding plate 142 is aligned and embedded in the sliding track 103. When the water inlet 143 is coaxial with the water inlet 104 on the side of the ship, the first electric hoist 161 stops.
[0053] 3) Fully lowered state;
[0054] The airbag 173 inflates to seal the sliding sleeve 140 and the hull inlet 104, and then the second electric hoist 162 continues to release the line until the inlet pipe 170 moves downward to the set depth below the required sea level.
[0055] It should be noted that the second cable 146 can both adjust the water intake depth of the inlet pipe 170 and resist the impact of the water flow on the inlet pipe 170, because during aquaculture, the workboat is moored at a single point and the water flow is from the bow to the stern.
[0056] In summary, the embodiments shown in the accompanying drawings are merely preferred solutions for achieving the objectives of this utility model. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this utility model. Other structural features derived therefrom should also fall within the scope of the solutions described in this utility model.
