Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a shellfish seedling raising system and a water temperature control device thereof. Background Art

[0002] Artificial shellfish seed cultivation is a key technology for increasing aquaculture species and restoring wild shellfish resources. However, the effectiveness of this technology is constrained by various environmental factors, with water temperature regulation being particularly critical. Research has shown significant differences in the reproductive cycles of different shellfish species. For example, the ideal artificial breeding period for the high-crowned scaly mussel and the unbalanced scaly mussel is January to March, while the plicatilis clams have dual reproductive peaks in spring and autumn (October-November and March-April). This diverse reproductive period leads to a year-round demand for seed production, posing significant challenges to the stability, accuracy, and environmental adaptability of water temperature control systems. Furthermore, efficient automated feeding to ensure the normal development of shellfish seed is crucial during the feeding process.

[0003] The invention patent application with publication number CN120167370A discloses a multi-purpose shellfish seedling breeding device, which relates to the field of aquaculture technology, including 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 staggered in the box body from left to right, so that a circuitous flow channel is formed in the box body. A drain outlet corresponding to the outlet position of the circuitous flow channel is provided on the box body, and the water level regulating mechanism is used to be arranged at the drain outlet to realize the adjustment of the water level in the box body.

[0004] It is found in the above-mentioned prior art that since the feed is generally in the form of floating algae and granular feed, these feeds will continue to float with the flow of aquaculture water. At the same time, the wave-making pump continuously exerts force on the surface of the aquaculture water, thereby forming artificial water waves. Although it is to simulate the seawater environment to promote the feeding of shellfish seedlings, the wave-making process will continue to affect the area where the feed flows, thereby affecting the feeding amount of shellfish seedlings, and then affecting the normal growth progress of shellfish seedlings. In addition, due to the influence of the environment, the heat in the aquaculture water is easily lost, and it is impossible to maintain a constant temperature.

[0005] Therefore, it is necessary to solve the above problems through a shellfish seedling raising system and a water temperature control device thereof. Summary of the Invention

The positions of the plurality of filter mesh holes on the second filter plate and the plurality of filter mesh holes on the first filter plate are staggered with each other.

[0012] Preferably, a feed bin for shellfish seedlings is provided on one side of the support frame, and a solenoid valve is provided at the bottom of the feed bin, and the solenoid valve is used to control the feed in the feed bin to feed the feed into the seedling chamber.

[0013] The present invention also provides a water temperature control device, including the shellfish seedling breeding system and breeding component described in the above technical solution, the breeding component includes a seedling breeding tray, and buoyancy chambers are provided on the left and right sides of the seedling breeding tray through a limiting frame, and the buoyancy chambers are used to provide buoyancy for the seedling breeding tray, and a wave-making pump is provided at the bottom of the seedling breeding tray through a mounting frame, and the seedling breeding tray is arranged inside the shellfish seedling breeding system.

[0014] Preferably, a first push rod is provided inside the two buoyancy chambers, and a piston push plate is provided at the output end of each of the two first push rods, and the outer surface of the piston push plate is in close contact with the inner wall of the buoyancy chamber; The two first push rods can drive the piston push plate to move along the interior of the buoyancy chamber, and as the two piston push plates move, the interior of the buoyancy chamber can be placed in a negative pressure state, and the aquaculture water in the seedling chamber can be absorbed into the interior of the buoyancy chamber.

[0017] 2. The present invention achieves water temperature balance through a spoiler structure, while also having efficient cleaning and anti-blocking functions. During water temperature regulation, the drive motor drives the rotating ring and spoiler blades to rotate, allowing the heat released by the heating component to diffuse evenly with the water flow, solving the problem of local uneven water temperature. During cleaning, the spoiler blades are controlled by strain gauge feedback, and the drive motor rotates forward and backward to scrape away excrement from the bottom of the chamber. A 45° deflection of the blades can enhance the cutting force, and the water pump is started synchronously to discharge the waste. In terms of anti-blocking, the double filter plates block the upward movement of impurities when they are fitted together. The high-speed rotation of the blades can crush large particles of foreign matter, and the downward movement of the filter plates squeezes the water flow, preventing blockage in the drain pipe and ensuring stable operation of the system.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] The present invention provides Figures 1 to 7A shellfish seedling raising system is shown, which includes a seedling raising bin assembly 1, and the seedling raising bin assembly 1 includes a seedling raising base 102, a seedling raising chamber 101 and a breeding assembly 2. The top of the seedling raising base 102 is connected to the bottom of the seedling raising chamber 101, and the seedling raising base 102 is used to support the bottom of the seedling raising chamber 101, so that the seedling raising chamber 101 will not have the risk of deviation and tipping during artificial breeding. Secondly, a drainage system is provided at the bottom of the seedling raising chamber 101, and the drainage system includes a drainage pipe 103, the end of the drainage pipe 103 is connected to the interior of the seedling raising chamber 101, and the drainage pipe 103 is connected to the interior of the seedling raising chamber 101. 3 is connected with a water pump 104 device, and a support base is provided at the bottom of the water pump 104, which can support the bottom of the water pump 104 device. Secondly, the other end of the water pump 104 is connected with a connecting pipe 105, and the end of the connecting pipe 105 close to the water pump 104 device is connected to the end of the drain pipe 103 away from the seedling chamber 101. The water pump 104 device can pump out the water in the seedling chamber 101 through the drain pipe 103 and use the mutual cooperation of the drain pipe 103 and the connecting pipe 105 to pump it out to the outside, thereby replacing the aquaculture water inside the seedling chamber 101.

[0023] A support frame 107 is fixedly provided on the outer surface of the seedling raising chamber 101, and a water pipe 108 is provided inside the support frame 107. The upper end of the water pipe 108 is located above the seedling raising chamber 101. Secondly, the bottom end of the water pipe 108 passes through the interior of the support frame 107 and is arranged on the outer surface of the support frame 107. The water pipe 108 is interconnected with the external liquid injection equipment, and can inject external water into the interior of the seedling raising chamber 101 through the water pipe 108 to inject aquaculture water, thereby realizing water injection and shellfish seedling cultivation. In addition, the water pipe 108 cooperates with the external liquid injection equipment to realize water injection into the seedling raising chamber 101, and the drainage pipe 103 is used to cooperate with the water pump 104 equipment and the connecting pipe 105 to realize the water in the seedling raising chamber 101 to be pumped out to the outside, so as to circulate the water in the seedling raising chamber 101 to ensure the healthy water quality during the shellfish seedling cultivation process.

[0024] A feed bin 109 for shellfish seedlings is provided on one side of the support frame 107, and a solenoid valve (not shown in the figure) is provided at the bottom of the feed bin 109. The solenoid valve is used to control the feed in the feed bin 109 to feed the inside of the seedling chamber 101, thereby achieving the purpose of automatically feeding feed during the shellfish seedling cultivation process.

[0025] The water temperature control device includes a breeding component 2, which includes a seedling tray 201. The seedling tray 201 has a plurality of filter holes on its inner wall. The diameter of the filter holes on the seedling tray 201 is smaller than that of the shellfish seedlings. This can prevent the shellfish seedlings from escaping from the filter holes on the seedling tray 201 to the outside. Secondly, two buoyancy chambers 203 are provided on the left and right sides of the seedling tray 201 through a limiting frame 202. The two buoyancy chambers 203 are symmetrically arranged on the left and right sides of the seedling tray 201. The two buoyancy chambers 203 can provide buoyancy to the seedling tray 201, so that the seedling tray 201 can float inside the seedling chamber 101.

[0026] A first push rod 204 is provided inside the two buoyancy chambers 203, and a piston push plate 208 is provided at the output end of the two first push rods 204. The outer surface of the piston push plate 208 is tightly fitted with the inner wall of the buoyancy chamber 203. The outer surface of the first push rod 204 is provided with a waterproof structure. The two first push rods 204 can drive the piston push plate 208 to move along the inside of the buoyancy chamber 203, and as the two piston push plates 208 move, the inside of the buoyancy chamber 203 can be placed in a negative pressure state, and the aquaculture water in the seedling chamber 101 can be absorbed into the inside of the buoyancy chamber 203, thereby achieving the purpose of adjusting the floating height of the seedling tray 201.

[0027] A mounting frame 205 is provided at the bottom of the seedling tray 201, and a wave-making pump 206 is provided on the inner side of the mounting frame 205. The wave-making pump 206 can drive the aquaculture water in the seedling chamber 101 to flow rapidly, thereby achieving the purpose of artificial wave creation, and further making the water flow, which is conducive to shellfish feeding. Secondly, a water temperature sensor is provided at the bottom of the wave-making pump 206. The water temperature sensor is always in contact with the aquaculture water inside the seedling chamber 101 and collects and detects the temperature data of the aquaculture water in the seedling chamber 101 in real time.

[0028] A driving motor 110 is provided at the bottom of the seedling raising chamber 101, and a drain pipe 103 is located on one side of the driving motor 110. When the drain pipe 103 cooperates with the water pump 104 and the connecting pipe 105 to discharge the aquaculture water in the seedling raising chamber 101 to the outside, it will not be affected by the driving motor 110 and the spoiler blades 121. A heating component is provided on the inner wall of the seedling raising chamber 101, and the heating component is specifically a common heating tube. After power is turned on, the aquaculture water inside the seedling raising chamber 101 is heated through the heating tube to ensure that the water temperature is always at a suitable aquaculture temperature during the shellfish seedling raising process.

[0029] When in use, first use the water pipe 108 in conjunction with the external liquid injection device to inject the aquaculture water required for aquaculture and seedlings into the seedling chamber 101, then place the seedling tray 201 containing shellfish seedlings inside the seedling chamber 101, and use the first push rods 204 in the two buoyancy chambers 203 to contract, so that negative pressure is generated inside the two buoyancy chambers 203 and the aquaculture water in the seedling chamber 101 is sucked into the buoyancy chamber 203 by relying on the water inlet at the end of the buoyancy chamber 203 away from the first push rod 204. After the inside is filled, the buoyancy adjustment purpose of the seedling tray 201 is achieved, and then the wave-making pump 206 set at the bottom of the seedling tray 201 through the mounting frame 205 is turned on, and the aquaculture water in the seedling chamber 101 is controlled to flow. First, it is to simulate the living environment of shellfish seedlings in seawater to ensure that the shellfish seedlings reduce rejection reactions during the cultivation process, and secondly, it is convenient for the shellfish seedlings to eat. At this time, the temperature sensor 207 at the bottom of the wave-making pump 206 is used to detect and collect the water temperature data in the seedling chamber 101 in real time.

[0030] If the temperature sensor 207 detects that the water temperature in the seedling chamber 101 is lower than the temperature threshold suitable for shellfish seedling cultivation, the heating tube on the inner wall of the seedling chamber 101 is immediately turned on to heat the aquaculture water inside the seedling chamber 101, thereby avoiding the shellfish seedlings from being unable to adapt to the water temperature of the aquaculture water due to the water temperature being too low, which may lead to unexpected situations.

[0031] Secondly, a feed bin 109 containing shellfish seedlings is set on one side of the support frame 107, and a solenoid valve is provided at the bottom of the feed bin 109. The solenoid valve is used to control the feed in the feed bin 109 to feed the feed into the seedling chamber 101, thereby achieving the purpose of automatically feeding feed during the shellfish seedling cultivation process, thereby saving additional human resources and achieving automated breeding effects.

[0032] When the specified time is reached, the solenoid valve is energized and in the open state, and the feed in the feed bin 109 on one side of the support frame 107 will be quickly put into the seedling chamber 101 through the solenoid valve. Most of the feed put in is in the form of floating algae or particles. The feed put in will continue to float on the surface of the aquaculture water in the seedling chamber 101, and the shellfish seedlings in the seedling tray 201 can eat normally to ensure normal growth.

[0033] Since the feed is generally in the form of floating algae and granular feed, these feeds will continue to float with the flow of aquaculture water. At the same time, the wave-making pump 206 at the bottom of the seedling tray 201 continuously applies force to the surface of the aquaculture water, thereby forming artificial water waves, which will continuously affect the area where the feed flows, thereby affecting the feeding effect of the shellfish seedlings. Therefore, the first push rod 204 in the buoyancy chamber 203 is used to drive the piston push plate 208 to move inside the buoyancy chamber 203, so as to adjust the buoyancy of the seedling tray 201, so that the four sides of the seedling tray 201 float toward the water surface in the seedling chamber 101, and the four sides of the seedling tray 201 are used to surround the feed bin 109 put into the seedling chamber, so as to avoid the process of the wave-making pump 206 making the water flow, so that the bait cannot be put into the feeding range of the shellfish seedlings, so as to ensure that the shellfish seedlings can eat evenly and normally.

[0034] Example 2

[0035] According to the temperature sensor 207 in Example 1, the water temperature data is monitored in real time, and the heating tube in the heating component is turned on according to the water temperature data to heat the aquaculture water in the seedling chamber 101, thereby raising the overall temperature of the aquaculture water until it meets the survival temperature that the shellfish seedlings can adapt to. However, during the heating process, the heating tube will first heat the aquaculture water within the range of the inner wall of the seedling chamber 101, so the heating efficiency is low, and it is impossible to uniformly and quickly heat the entire aquaculture in the seedling chamber 101. Therefore, this solution proposes Example 2, and the specific adjustment plan is as follows: A second push rod 112 is provided on both sides of the inner wall of the seedling chamber 101 through two fixed blocks 111, and a waterproof structure is provided on the surface of the multiple second push rods 112, and the two fixed blocks 111 are symmetrically distributed on the left and right sides of the inner wall of the seedling chamber 101, and the two second push rods 112 are symmetrically arranged on the left and right sides of the seedling chamber 101, and the output end of each second push rod 112 is arranged on the top of the first filter plate 113, and the two second push rods 112 are symmetrically arranged on the left and right sides of the first filter plate 113, respectively. The first filter plate 113 is located inside the seedling chamber 101, and a second filter plate 114 is provided at the bottom of the first filter plate 113, and a telescopic push rod 115 is provided at the bottom of the second filter plate 114, and a magnetic block is provided at the end of the telescopic push rod 115 away from the second filter plate 114.

[0036] Secondly, an electromagnet 116 that is adapted to the magnetic block is provided at the end of the telescopic push rod 115 near the second filter plate 114. The telescopic push rod 115 is fixedly arranged on one side of the inner wall of the seedling chamber 101, and the telescopic push rod 115 is located below the second filter plate 114. The electromagnet 116 can generate magnetic force on the magnetic block and drive the telescopic push rod 115 to contract, so that the distance between the first filter plate 113 and the second filter plate 114 is reduced until the bottom of the first filter plate 113 and the top of the second filter plate 114 are tightly fitted with each other. The electromagnet 116 is provided with a built-in power supply, and the power supply circuit is provided with an insulating layer, so that it can work independently underwater without leakage.

[0037] When the temperature sensor 207 detects that the temperature of the aquaculture water is lower than the temperature suitable for the survival of shellfish seedlings, the heating component is turned on and the power is supplied through the heating tube to heat the aquaculture water in the seedling chamber 101. In this process, the rotating ring 117 is driven to rotate by the driving motor 110, so that the rotation of the rotating ring 117 drives the multiple driving rods 118 and the spoiler blades 121 to rotate in the bottom area of ​​the seedling chamber 101, and the multiple spoiler blades 121 are used to generate turbulence for the aquaculture water at the bottom of the seedling chamber 101, and then the second push rods 112 on the left and right sides of the inner wall of the seedling chamber 101 are controlled to drive the first filter plate 113 and the second filter plate 114 to do reciprocating movement inside the seedling chamber 101. The first filter plate 113 and the second filter plate 114 move upward and downward, thereby driving the aquaculture water in the nursery chamber 101 to move in the longitudinal direction and cause turbulence, thereby promoting the efficiency of the heating tube in transferring heat to the aquaculture water in the nursery chamber 101, and making the aquaculture water in the nursery chamber 101 evenly heated. At the same time, when the temperature reaches the specified range, the driving rod 118 and the turbulence blade 121 are still kept in the working state, which can continuously generate a turbulence state for the aquaculture water, so as to ensure that after the temperature is lost due to the influence of the environment, the heating tube and the turbulence can quickly replenish the lost temperature, thereby achieving a constant temperature effect of the aquaculture water, so as to ensure that the shellfish seedlings are always in a suitable growth environment.

[0038] Example 3

[0039] According to Example 2, it is found that during the long-term shellfish seedling cultivation process, the shellfish seedlings will discharge a large amount of excrement, and precipitate at the bottom of the inner wall of the seedling chamber 101 or adhere to the surface of the inner wall of the seedling chamber 101. If it is not cleaned for a long time, the degree of pollution of the aquaculture water will be accelerated, and a large number of shellfish seedlings will die. Therefore, this solution proposes Example 3, which is specifically as follows: A rotating ring 117 is provided at the output end of the drive motor 110, and a drive rod 118 is provided on the outer surface of the rotating ring 117. A spoiler blade 121 is provided at the end of the drive rod 118 away from the drive motor 110, and the spoiler blade 121 can be deflected along the axis of the drive rod 118, and a micro motor 122 is provided at the end of the spoiler blade 121 close to the drive rod 118. The micro motor 122 is arranged inside the drive rod 118, and a waterproof structure is provided on the outer surface of the micro motor 122 (not shown in the figure) to ensure that the micro motor 122 will not have the risk of short circuit or leakage during operation. Secondly, the power supply method of the micro motor 122 is a built-in battery installation method, so that it can be independently fixed inside the seedling chamber 101 without external power supply. Secondly, when the micro motor 122 is started, it can drive the spoiler blade 121 to deflect along the axis of the drive rod 118, and the micro motor 122 is located inside the drive rod 118 near the spoiler blade 121.

[0040] In addition, a plurality of filter mesh holes are provided on the surface of the first filter plate 113, and the shape of the plurality of filter mesh holes is set to be "D" shape. Secondly, a plurality of filter mesh holes are provided on the surface of the second filter plate 114, and the shape of the plurality of filter mesh holes on the second filter plate 114 is set to be inverted "D" shape. The positions of the plurality of filter mesh holes on the second filter plate 114 and the plurality of filter mesh holes on the first filter plate 113 are staggered with each other. When the first filter plate 113 and the second filter plate 114 control the telescopic push rod 115 to retract through the electromagnet 116, the first filter plate 113 and the second filter plate 114 are attached to each other, and the aquaculture water in the seedling chamber 101 will be divided into two by the first filter plate 113 and the second filter plate 114, and the water above the first filter plate 113 cannot pass through the first filter plate 113 and the second filter plate 114 to enter the area below the second filter plate 114.

[0041] At least three drive rods 118, micro motors 122 and spoiler blades 121 are provided, and each drive rod 118, micro motor 122 and spoiler blade 121 is distributed in a circular array on the outer surface of the rotating ring 117. A strain gauge is provided on the surface of one spoiler blade 121. The detection range of the strain gauge covers the surface of the spoiler blade 121. The strain gauge cooperates with the pressure sensor to detect the pressure data exerted on the spoiler blade 121 during the rotation process. The pressure sensor is provided inside the spoiler blade 121 (not shown in the figure). A reset torsion spring 123 is provided on the outer side of the drive rod 118. The reset torsion spring 123 is fixed at one end away from the drive rod 118. The outer surface of the rotating ring 117 is fixedly arranged, and the reset torsion spring 123 is used to reset the driving rod 118 and the spoiler blade 121. The surface of the rotating ring 117 is provided with a third push rod 106, and the output end of the third push rod 106 is provided with a limiting pressure plate 119. The middle area of ​​the limiting pressure plate 119 is movably arranged on the outer surface of the guide rod 120, and the bottom end of the guide rod 120 is fixedly connected to the output end of the driving motor 110. In the initial state, the bottom of the limiting pressure plate 119 and the outer surface of the plurality of driving rods 118 are used to apply a limiting force, so that the spoiler blade 121 is always in contact with the inner wall surface of the bottom of the seedling chamber 101. The specific adjustment steps are as follows: During the heating process, the driving motor 110 is used to drive the rotating ring 117 to rotate at the bottom of the seedling chamber 101, which will drive multiple driving rods 118 and the spoiler blades 121 to rotate along the bottom of the seedling chamber 101 and cause turbulence to the aquaculture water in the bottom area of ​​the seedling chamber 101. Then, the movement state of the first filter plate 113 and the second filter plate 114 is coordinated to realize the auxiliary heating tube after starting and cooperating with the aquaculture water in the turbulent state, so as to achieve a uniform heating state of the aquaculture water as a whole. Secondly, the spoiler blades 121 move along the bottom surface of the inner wall of the aquaculture chamber. During the process, the strain gauge is used to detect the bottom surface of the inner wall of the seedling chamber 101. If the strain gauge is combined with the pressure sensor to detect that the spoiler blade 121 has a higher pressure data during the movement, it is judged that there is foreign matter adhering or sticking here. At this time, the drive motor 110 is immediately controlled to rotate back and forth. In this way, the drive rod 118 and the spoiler blade 121 can be used to frequently scrape and clean the foreign matter adhering to the surface of the bottom of the inner wall of the seedling chamber 101, and then the strain gauge is used again to cooperate with the pressure sensor to detect the foreign matter adhering to the bottom surface of the inner wall of the seedling chamber 101.

[0042] If there is still pressure data, it means that there is still foreign matter adhering or excrement. At this time, the third push rod 106 is controlled to extend and drive the limit pressure plate 119 to move along the outer surface of the guide rod 120 toward the end of the guide rod 120 away from the drive motor 110, so that the limit pressure plate 119 no longer applies a limiting force to the outer surface of the drive rod 118. In this way, the drive rod 118 and the spoiler blade 121 will move closer to the axis of the drive motor 110 through the force of the reset torsion spring 123, turning on the micro motor. The machine 122 rotates along the axis of the driving rod 118, and drives the spoiler blade 121 to deflect at the end of the driving rod 118, so that the spoiler blade 121 is close to the bottom surface of the inner wall of the seedling chamber 101 at a 45° angle, and the spoiler blade 121 is always in contact with the inner wall surface close to the bottom of the seedling chamber 101, which can enhance the cutting force of the spoiler blade 121 on the bottom inner wall surface of the seedling chamber 101, thereby further enhancing the cleaning effect of adhesions or excrement of shellfish seedlings.

[0043] At the same time, when the driving motor 110 drives the driving rod 118 and the spoiler blade 121 to rotate through the rotating ring 117, in order to prevent the cleaned adhered foreign matter or excrement of the shellfish seedlings from contacting the upper shellfish seedlings and causing bacterial infection, it is necessary to control the electromagnet 116 on the second filter plate 114 to generate magnetic force on the magnetic block at the bottom of the telescopic push rod 115 before cleaning, so that the telescopic push rod 115 is extended, which can drive the second filter plate 114 to move in the direction of the first filter plate 113, and then control the second push rod 112 to extend and drive the first filter plate 113 to move in the direction of the second filter plate , and make the surface of the first filter plate 113 facing the second filter plate 114 fit together with it. Since the first filter plate 113 and the second filter plate 114 are both provided with a plurality of "D"-shaped filter mesh holes and their positions are staggered, when the first filter plate 113 and the second filter plate 114 are in a state of mutual fit, the aquaculture water in the bottom area of ​​the seedling chamber 101 and the cleaned adhered foreign matter or excrement of the shellfish seedlings cannot pass through the first filter plate 113 and the second filter plate 114 into the upper area of ​​the seedling chamber 101, thereby avoiding the cleaned excrement and foreign matter impurities from contaminating the shellfish seedlings and causing property losses.

[0044] In addition, during the cleaning process, the water pump 104 is always kept in the open state, and the connecting pipe 105 and the drain pipe 103 are used to quickly discharge the aquaculture water mixed with the cleaned foreign matter and shellfish excrement at the bottom of the seedling chamber 101 to the outside. Then, during the drainage process, the water pipe 108 is used to continuously inject fresh aquaculture water into the interior of the seedling chamber 101, so as to achieve fast and efficient water replacement, and at the same time avoid the dirty aquaculture water from contacting with shellfish seedlings, resulting in property loss. Therefore, after the adhering excrement and the generated biofilm are cleaned by the spoiler blade 121, the first filter plate 113 and the second filter plate 114 are used to clean the adhering excrement and the generated biofilm. The two filter plates 114 overlap with each other to form a sealed area, so that the turbid aquaculture water below cannot enter the upper area of ​​the seedling chamber 101. Then, the sewage containing excrement and impurities is pumped out to the outside by the water pump 104, and then the water pipe 108 is used to inject water into the interior of the seedling chamber 101, thereby achieving the purpose of replacing the aquaculture water. During the water change process, the first filter plate 113 and the second filter plate 114 are gradually separated, so that the water in the upper area can also be replaced. If the drainage speed is higher than the water inlet speed, the seedling tray 201 can temporarily float on the surface of the first filter plate 113, which can avoid direct contact between the seedling tray 201 and the sewage.

[0045] When the water pump 104 equipment cooperates with the connecting pipe 105 and the drain pipe 103 to form a blockage during the drainage process, the third push rod 106 is controlled to push the limit pressure plate 119 to the top position of the guide rod 120, so that the driving rod 118 will be driven by the return torsion spring 123 to drive the spoiler blade 121 to move closer to the axial direction of the guide rod 120. At this time, one side of the spoiler blade 121 no longer contacts the inner wall surface of the bottom of the seedling chamber 101, and the micro motor 122 is controlled to drive the spoiler blade 121 to rotate continuously along the end axis of the driving rod 118, and cooperate with the driving motor 110 to drive the rotating ring 117 to rotate and drive multiple driving rods 118 and the spoiler blade 121 to rotate. The filter element 113 is rotated to separate and crush larger foreign matter and impurities at the bottom of the inner wall of the seedling raising chamber 101, and at the same time, the second push rod 112 is controlled to drive the first filter plate 113 to move in the direction of the second filter plate 114, and at the same time, the electromagnet 116 on the telescopic push rod 115 is controlled to generate magnetic attraction with the magnetic block, so that the telescopic push rod 115 will contract, so that the first filter plate 113 and the second filter plate 114 can always remain in contact with each other and move synchronously in the direction of the drive motor 110. Since the first filter plate 113 and the second filter plate 114 always remain in contact with each other, pressure is applied to the connection between the drain pipe 103 and the seedling raising chamber 101, thereby further preventing blockage inside the drain pipe 103.
