Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a multi-purpose shellfish seedling breeding system. Background Technology

[0002] Traditional shellfish seedling cultivation systems employ a single-layer, floor-mounted model, which fails to fully utilize the space within the temperature-controlled chamber where the system is located. Furthermore, the water flow in traditional pearl mussel and other shellfish seedling cultivation devices is a linear, point-to-point flow. Without human intervention to replenish nutrients, the water flows directly to the outlet, resulting in seedlings in the four corners and most of the pond not receiving fresh nutrients. This can lead to localized nutrient deficiencies, causing some seedlings to develop poorly, vary in size, and be inconsistent in specifications. Additionally, the water level in traditional shellfish seedling cultivation devices is not adjustable, limiting their functionality to the cultivation of seedlings. Moreover, the shellfish seedling cultivation season is short, generally from March to June, leaving the devices idle at other times, resulting in low utilization rates. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide a multi-purpose shellfish seedling system that can make full use of the effective thermal energy space in the constant temperature room where it is located, avoiding the problem of insufficient local nutrient supply, which leads to poor development, inconsistent size, and inconsistent specifications of some seedlings. It has more diversified functions and improves utilization rate and economic benefits.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-4As shown, this embodiment provides a multi-purpose shellfish seedling cultivation system 100, including a seedling support, a water supply device, a water recycling device, and multiple shellfish seedling devices 9. The seedling support has multiple receiving layers arranged sequentially from bottom to top, and each receiving layer includes at least one receiving unit. The shellfish seedling device 9 includes a box body, a water level regulating mechanism, and multiple baffles. The upper end of the box body is an open structure, and the multiple baffles are arranged alternately from left to right in the box body, forming a meandering flow channel in the box body. A drain outlet 913 corresponding to the outlet position of the meandering flow channel is provided on the front side of the box body. The water level regulating mechanism is used to adjust the water level in the box body by being located at the drain outlet 913, thereby enabling the shellfish seedling device 9 to be used for shellfish seedling cultivation or the cultivation of other aquatic products. Each tank is used to slide horizontally into a housing unit. The water supply device is used to supply water to the inlet of each meandering flow channel. The water recovery device is used to recover the water discharged from each drain outlet 913 and transport it to the water supply device. The water circulation in the tank is achieved through the cooperation of the water recovery device and the water supply device.

[0027] The multi-purpose shellfish seedling system 100 in this embodiment adopts a multi-layer seedling mode, making full use of the effective thermal space within the constant temperature chamber where the multi-purpose shellfish seedling system 100 is located. Under the premise of achieving the same seedling production, it achieves energy saving and emission reduction compared to the single-layer seedling mode. The shellfish seedling device 9 has a meandering flow channel, in which water flows throughout the entire tank and is then discharged through the drain outlet 913. This ensures that the seedlings in each area of ​​the tank can absorb fresh nutrients, avoiding problems such as insufficient local nutrient supply, which could lead to poor development, inconsistent size, and uneven specifications of some seedlings. This results in the production of high-quality shellfish seedlings with uniform specifications and good development.

[0028] During use, the water level adjustment mechanism can be used to maintain a low water level in the tank to meet the needs of shellfish seedling cultivation. During the non-seedling season, the water level can be raised to meet the needs of other aquatic product cultivation. Specifically, a batch of short-growing-cycle aquatic products, such as snails, shrimp, and tropical fish, can be cultivated in the tank. The water level adjustment mechanism allows the shellfish seedling cultivation device 9 in this embodiment to achieve shellfish seedling cultivation and the cultivation of other aquatic products at different times, realizing the dual-purpose nature of the shellfish seedling cultivation device 9, making its functions more diversified, avoiding idleness, improving the utilization rate of the shellfish seedling cultivation device 9, and increasing economic benefits.

[0029] The seedling support includes multiple vertical supports 1 and multiple multi-layer support mechanisms. The vertical supports 1 are arranged sequentially from left to right and are parallel to each other. A multi-layer support mechanism is set between any two adjacent vertical supports 1. Each multi-layer support mechanism includes multiple support components arranged sequentially from bottom to top. Each support component includes a horizontal support, two side supports 4 and two sliding support tubes 8. The periphery of the horizontal support is connected to the two vertical supports 1. The lower part of the two side supports 4 is connected to the two sides of the upper part of the two horizontal supports, and the upper part of the two side supports 4 is connected to the two vertical supports 1. A sliding support tube 8 extending from front to back is set on the side of the upper part of each side support 4 closest to the other side support 4. Each support component and the two adjacent vertical supports 1 form a housing unit. The two sides of the box are used to slide on the two sliding support tubes 8 of each support component. The horizontal support of each support component is used to support one box.

[0030] In this embodiment, each sliding support tube 8 is connected to the side bracket 4 through multiple connecting components arranged sequentially from front to back. The connecting components include an inclined connecting rod 7 and two horizontal connecting rods 6. The top of the sliding support tube 8 is flush with the top of the side bracket 4. Both ends of each horizontal connecting rod 6 are connected to the top of the sliding support tube 8 and the top of the side bracket 4, respectively. The two horizontal connecting rods 6 converge at one point on the sliding support tube 8. The upper end of the inclined connecting rod 7 is connected to the sliding support tube 8, and the lower end is connected to the side bracket 4. The inclined connecting rod 7 is located in the lower part between the two horizontal connecting rods 6.

[0031] By setting multiple connecting components, and in each connecting component, the inclined connecting rod 7 and the two horizontal connecting rods 6 cooperate to make the sliding support tube 8 firmly installed on the side bracket 4.

[0032] In this embodiment, each accommodating layer includes multiple accommodating units arranged sequentially along the horizontal direction. Specifically, the support components located at the same horizontal position in the multiple multi-layer support mechanisms are located in the same accommodating layer.

[0033] In this specific embodiment, the seedling support includes three vertical supports 1 and two multi-layer support mechanisms, each of which includes four support components arranged sequentially from bottom to top.

[0034] In order to limit the rear end of the box, each support component also includes a rear stop bracket 5.

[0035] Each horizontal support has a receiving component 20 at its front, and each receiving component 20 is used to hold a record card. The record card is used to record the identity information of the corresponding shellfish in the shellfish seedling device 9. In this embodiment, the record card records the identity information of the color-series mussel seedlings in the shellfish seedling device 9, which facilitates the overall orderly and partitioned management of the large color gene bank.

[0036] In this embodiment, the horizontal support includes a rectangular frame 2 and support rails 3 arranged sequentially from left to right in the rectangular frame 2. The periphery of the rectangular frame 2 is connected to two vertical supports 1. The multiple support rails 3 are parallel to each other and extend from front to back to support the box.

[0037] Specifically, the receiving component 20 is disposed at the front of the rectangular frame 2. In this embodiment, the receiving component 20 is a transparent receiving shell that is open at the top and closed at the bottom.

[0038] In this specific embodiment, the vertical support 1, the horizontal support, the side support 4, the rear support 5, the connecting components, and the sliding support tube 8 are all made of steel.

[0039] To ensure the stability of the entire seedling support frame, a horizontal support block 21 is installed at the bottom of the vertical support 1.

[0040] The water recycling device includes a thermostatic tank 12, a pumping mechanism, a recycling pipe 11, and multiple water collection tanks 10. Each of the multiple horizontal supports on the same floor has a water collection tank 10 below it to receive water discharged from the drain outlet 913. Each water collection tank 10 is installed at the front of multiple vertical supports 1. One end of the water collection tank 10 is closed, and the other end is connected to the recycling pipe 11. In this embodiment, the water collection tank 10 is inclined downwards from the end furthest from the recycling pipe 11 to the end closest to the recycling pipe 11, facilitating the flow of water from the water collection tank 10 into the recycling pipe 11. The recycling pipe 11 is connected to the thermostatic tank 12, and the pumping mechanism is used to transport the water in the thermostatic tank 12 to the water supply device.

[0041] The thermostatic tank 12 in this embodiment can maintain a constant temperature of the water inside and can be used to raise fish, thereby making full use of the thermostatic tank 12. Specifically, the fish raised is yellow catfish.

[0042] Specifically, the pumping mechanism includes a booster pump 13 and a pumping pipe 14. The booster pump 13 is installed in the constant temperature tank 12, and the two ends of the pumping pipe 14 are connected to the booster pump 13 and the water supply device, respectively.

[0043] The water supply device includes an elevated support 15 and an elevated water storage tank 16 located on the upper part of the elevated support 15. A pumping mechanism is used to transport water from the constant temperature tank 12 to the elevated water storage tank 16. In this embodiment, the end of the pumping pipe 14 away from the lift pump 13 is connected to the top of the elevated water storage tank 16. A controllable water inlet component is provided above the inlet of each meandering flow channel. Each controllable water inlet component is connected to the elevated water storage tank 16 through a main water inlet pipe 18. The bottom of the elevated water storage tank 16 is set at a height higher than the height of the uppermost controllable water inlet component, so that the water in the elevated water storage tank 16 can flow to each controllable water inlet component under the action of gravity.

[0044] In this embodiment, the controllable water inlet component is a faucet 19. Each faucet 19 is installed above a rear support bracket 5 and above the inlet of a meandering flow channel. Each faucet 19 is connected to the main water inlet pipe 18 through a branch water inlet pipe. The main water inlet pipe 18 is connected to the lower part of one side of the high-level water storage tank 16.

[0045] The water supply device also includes a float switch 17 and a controller. The float switch 17 is installed in the high-level water storage tank 16, and both the float switch 17 and the pumping mechanism are connected to the controller. In this embodiment, the lift pump 13 is connected to the controller.

[0046] The float switch 17 is used to monitor the water level in the high-level water storage tank 16. When the water level in the high-level water storage tank 16 reaches the minimum set value, the controller controls the pumping mechanism to start pumping water into the high-level water storage tank 16; when the water level in the high-level water storage tank 16 reaches the maximum set value, the controller controls the pumping mechanism to shut down.

[0047] like Figure 3 As shown, the shellfish seedling device 9 also includes two support plates 94, which are respectively set on the left and right sides of the box. The lower part of the support plate 94 is provided with an arc-shaped groove 95 that matches the structure of the sliding support tube 8 along its own length direction. A pull ring 919 is provided on the outside of the side of the box where the drain outlet 913 is provided.

[0048] By setting an arc-shaped groove 95, the two support plates 94 can be slidably installed on the two sliding support tubes 8 of the seedling support. Furthermore, by setting a pull ring 919 on the outside of the box, it is easy to manually pull the box to slide on the sliding support tube 8, so as to facilitate inspection, management and seedling collection.

[0049] To facilitate seedling collection, each baffle in this embodiment is detachably mounted on the box. The detachable design of the baffles allows for easy removal of the baffles after the seedlings mature, enabling the use of a large, dense net to scoop out shellfish seedlings approximately 1 cm in size from inside the box.

[0050] The upper parts of both the front and rear sides of the enclosure are provided with slots for installing baffles. The slots on the upper front side of the enclosure and the slots on the upper rear side of the enclosure are staggered, and one end of each baffle is used to snap into a slot.

[0051] In this specific embodiment, a slot for installing a baffle plate is provided on the upper part of both the front and rear sides of the housing, and the two slots are staggered.

[0052] like Figure 4 As shown, the slot includes a strip groove and a connecting groove disposed inside the strip groove and perpendicular to each other. The connecting groove penetrates the inner wall of the box. The baffle includes a strip plate 97 and a water flow baffle 96 disposed perpendicularly on one side of the strip plate 97. The strip plate 97 is used to insert into the strip groove, and the end of the water flow baffle 96 near the strip plate 97 is used to insert into the connecting groove. The water flow baffle 96 can contact the bottom of the box.

[0053] The shellfish seedling device 9 also includes a top limiting mechanism. The two ends of the top limiting mechanism are respectively set on two support plates 94 and are used to press on the upper part of multiple water flow baffles 96, so that the water flow baffles 96 contact the bottom of the box, preventing the water flow baffles 96 from floating up under the buoyancy of the water, and preventing water from passing under the water flow baffles 96 and losing the water circulation function.

[0054] The top limiting mechanism includes a pressure strip 98 and two limiting components. A positioning plate 99 is provided on the upper part of both ends of the pressure strip 98. A groove for pressing the pressure strip 98 is provided on the upper part of each flow baffle 96. The two positioning plates 99 are respectively used to be placed on the upper part of the two support plates 94. The two limiting components are respectively set on the upper part of the two support plates 94. Each limiting component is used to limit one positioning plate 99.

[0055] The limiting assembly includes a fixing block and a pressure plate 912. The fixing block and pressure plate 912 are located on both sides of the positioning plate 99. The fixing block includes a vertical plate 910 fixed on the support plate 94 and a horizontal plate 911 set on one side of the top of the vertical plate 910. The pressure plate 912 is rotatably installed on the support plate 94 via a pivot. The pressure plate 912 can rotate to the top of the positioning plate 99, and its upper and lower sides can be tightly fitted with the horizontal plate 911 and the positioning plate 99 respectively, thereby limiting the positioning plate 99. By limiting the two positioning plates 99, the top of the pressure strip 98 is limited, so that the pressure strip 98 can be firmly pressed onto the upper part of the multiple water flow baffles 96.

[0056] In this embodiment, the multiple water flow baffles 96 are parallel to each other, and all of the multiple water flow baffles 96 are perpendicular to the pressure strip 98.

[0057] To facilitate the installation of the water level adjustment mechanism, the drain outlet 913 extends through the top of the housing, and slots 914 are provided on the two inner sides opposite to the drain outlet 913, into which the water level adjustment mechanism is inserted.

[0058] The water level regulating mechanism includes a water level regulating insert plate 915 and a water level regulating spare insert plate 916. The water level regulating insert plate 915 and the water level regulating spare insert plate 916 have different heights. The slot 914 is used to insert either the water level regulating insert plate 915 or the water level regulating spare insert plate 916. The height of the water level regulating spare insert plate 916 is greater than the height of the water level regulating insert plate 915.

[0059] The water level regulating plate 915 is used to ensure that the water level in the tank meets the needs of shellfish seedlings, and the water level regulating spare plate 916 is used to ensure that the water level in the tank meets the needs of other aquatic products besides shellfish seedlings.

[0060] In this specific embodiment, multiple water level regulating backup plates 916 are provided, and the heights of the water level regulating plates 915 and the multiple water level regulating backup plates 916 are all different.

[0061] In this embodiment, the vertical distance between any two adjacent horizontal supports is 90cm, and the height of the box is between 50cm and 80cm. Since the water level required for pearl mussel seedling breeding is about 20cm, while the breeding of other aquatic products generally requires a water level of more than 50cm, the function of the water level adjustment spare plate 916 is designed to adjust the water level for different breeding species. This makes the shellfish seedling breeding device 9 in this embodiment have multiple uses, improves the applicability of the device, and thus can give full play to the utilization value of the shellfish seedling breeding device 9.

[0062] To guide the water discharged from drain outlet 913, a guide plate corresponding to the position of drain outlet 913 is installed on the outside of the tank. The end of the guide plate away from drain outlet 913 is located above the water collection tank 10. The guide plate includes a guide bottom plate 917 and two guide side plates 918. One end of the guide bottom plate 917 and one end of the two guide side plates 918 are fixed to the outside of the tank. The guide bottom plate 917 corresponds to the bottom position of drain outlet 913, and the two guide side plates 918 correspond to the two sides of drain outlet 913 respectively. The bottom of the two guide side plates 918 is connected to the two sides of the upper part of the guide bottom plate 917 respectively.

[0063] In order to facilitate the outflow of water from the drain outlet 913, the guide plate 917 is inclined downward from one end connected to the box to the other end away from the box.

[0064] In this embodiment, the box is a rectangular box with an open top, including a base plate 91 and two parallel first side plates 92 and two parallel second side plates 93 disposed on the base plate 91. The front and rear ends of one first side plate 92 are respectively connected to one end of the two second side plates 93, and the front and rear ends of the other first side plate 92 are respectively connected to the other ends of the two second side plates 93. Each support plate 94 is disposed on the upper part of the outer side of one first side plate 92. The upper part of each of the two second side plates 93 is provided with a slot, and the strip groove in the slot extends along the length direction of the second side plate 93. The connecting groove in the slot penetrates the inner wall of the second side plate 93. The drain outlet 913 is disposed on the front second side plate 93 and penetrates the upper end of the second side plate 93. One end of the flow guide bottom plate 917 and one end of the two flow guide side plates 918 are fixed to the outside of the front second side plate 93. The pull ring 919 is disposed on the outside of the front second side plate 93. Specifically, there are two pull rings 919.

[0065] In this specific embodiment, the housing and the two support plates 94 are an integral structure and are made of plastic. The baffle plate, pressure strip 98, and positioning plate 99 are all made of plastic.

[0066] The specific usage process is as follows: First, the shellfish seedling device 9 is processed. Specifically, each baffle plate is inserted into a slot, and the pressure strip 98 is inserted into the groove of each baffle plate. Each pressure plate 912 is rotated to be above a positioning plate 99, so that its upper and lower sides can be tightly fitted with the horizontal plate 911 and the positioning plate 99 respectively, thereby limiting the two positioning plates 99 and the pressure strip 98. Water level adjustment plates 915 are inserted into the two slots 914 of the drain outlet 913. Bottom mud is laid at the bottom of the tank, and shellfish seedlings are placed in it.

[0067] Each shellfish seedling device 9 is placed on top of a support assembly. Two support plates 94 on both sides of the box are slidably installed on two sliding support pipes 8, and a horizontal bracket supports the box. The inlet of the meandering flow channel is located below a faucet 19, and the guide plate is located above a water collection tank 10. When the faucets 19 are turned on, the water in each box flows in the meandering flow channel and is finally discharged into the water collection tank 10 through the drain outlet 913 and the guide plate. After that, it enters the constant temperature tank 12 through the recovery pipe 11. When the float switch 17 detects that the water level in the high-level water storage tank 16 has reached the minimum set value, the controller controls the lift pump 13 to start pumping water into the high-level water storage tank 16; when the float switch 17 detects that the water level in the high-level water storage tank 16 has reached the maximum set value, the controller controls the lift pump 13 to shut down.

[0068] When it is time to collect the seedlings, turn off all the water taps 19, pull the box outward, move the pressure plate 912 so that it is no longer pressed on the positioning plate 99, remove the pressure strip 98, and then continue to remove the baffle plates. Use a large mesh net to scoop out shellfish seedlings of about 1 cm in size from inside the box.
