[0028] Example 1: As Figures 1 to 7As shown in the figure, the rapid separation device for juvenile shrimp used in the present application includes a housing 10, a partition housing 20, a separation plate 30, a driving component 40, a water circulation mechanism 50, a plurality of soft hair bundles 60, a power component and a control unit.

[0029] The upper end of the housing 10 is open, and a growth lamp assembly 12 is provided at the top of the housing 10.

[0030] It should be noted that the growth lamp assembly 12 includes a growth lamp and related components, which are used to provide a living environment for juvenile shrimp. The growth lamp assembly 12 is a prior art and will not be elaborated here.

[0031] An oxygen supply component 13 is provided inside the housing 10.

[0032] It should be noted that the oxygen supply component 13 is used to supply oxygen to juvenile shrimp. The oxygen supply component 13 is a prior art and will not be elaborated here.

[0033] A collection pipe 11 is connected to the bottom of the housing 10. A switch valve may be provided on the collection pipe 11, and the collection pipe 11 is located below the separation plate 30.

[0034] The partition housing 20 is arranged inside the housing 10 through a plurality of brackets 21. One end of the bracket 21 is connected to the outer wall of the partition housing 20, and the other end of the bracket 21 is connected to the housing 10.

[0035] It should be noted that the plurality of brackets 21 can be 2, 3, 4, 5, 6 brackets 21, etc. The specific number is selected according to actual needs and will not be elaborated here.

[0036] The partition housing 20 is a hollow outer shell with openings at both the upper and lower ends, and a placement table 22 is arranged inside the partition housing 20.

[0037] There is a gap between the outer wall of the partition housing 20 and the inner wall of the housing 10 for juvenile shrimp to swim through. The size of this gap is selected according to actual needs and will not be elaborated here.

[0038] It should be noted that breeding shrimp can be placed on the placement table 22.

[0039] The separation plate 30 is rotatably arranged inside the housing 10, and the separation plate 30 is located below the partition housing 20.

[0040] It should be noted that there is a height difference between the bottom surface of the partition housing 20 and the top surface of the separation plate 30, so that juvenile shrimp can swim away from between the partition housing 20 and the separation plate 30. The specific value of this height difference is selected according to actual needs and will not be elaborated here.

[0041] The driving component 40 is arranged on the inner bottom surface of the housing 10, and the driving shaft of the driving component 40 is connected to the separation plate 30.

[0042] Among them, the driving component 40 can be a rotating motor.

[0043] It should be noted that the separation plate 30 can be rotatably arranged inside the housing 10 through a slide rail.

[0044] The water circulation mechanism 50 is installed on the outer wall of the housing 10. The water inlet of the water circulation mechanism 50 is communicated with the inside of the housing 10, and the water inlet of the water circulation mechanism 50 is located below the separation plate 30.

[0045] An isolation cover 51 is arranged on the water inlet of the water circulation mechanism 50 to prevent juvenile shrimps from being sucked into the water circulation mechanism 50.

[0046] The water outlet of the water circulation mechanism 50 is communicated with the inside of the housing 10. A water outlet pipe 52 is connected to the water outlet of the water circulation mechanism 50, and one end of the water outlet pipe 52 away from the water circulation mechanism 50 extends to the upper end opening of the partition housing 20.

[0047] It should be noted that the water circulation mechanism 50 is used to pump the water below the separation plate 30 into the partition housing 20. A filtering and purifying structure can also be arranged inside the water circulation mechanism 50. The water circulation mechanism 50 is a prior art and will not be described in detail here.

[0048] Furthermore, as Figure 2 shown, a plurality of separation holes 31 are formed in the separation plate 30.

[0049] It should be noted that the plurality of separation holes 31 can be 55, 56, 57, 58, 59 separation holes 31, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0050] It should be noted that the juvenile shrimps can swim to below the separation plate 30 through the separation holes 31. The specific aperture of the separation holes 31 is selected according to actual needs and will not be described in detail here.

[0051] Furthermore, as Figure 2 shown, a plurality of soft hair bundles 60 are arranged on the separation plate 30.

[0052] It should be noted that the plurality of soft hair bundles 60 can be 30, 31, 32, 33, 34 soft hair bundles 60, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0053] It should be noted that each soft hair bundle 60 is composed of a plurality of soft hairs. The soft hair bundles 60 can provide a place for the juvenile shrimps to play and hide, improving the survival rate of the juvenile shrimps.

[0054] It should be noted that the length of the soft hair bundles 60 is selected according to actual needs and will not be described in detail here.

[0055] The power component is used to supply energy for the operation of the device, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of each component of the device, preferably a programmable logic controller; both are prior arts and will not be elaborated here.

[0056] It can be understood that the water circulation mechanism 50 is used to realize the circulating flow of water. Through the settings of the water inlet and outlet, an up-and-down circulating water flow is formed. At the same time, the circulating water can promote the swimming and separation of juvenile shrimps; through the separation holes 31 on the separation plate 30 and the rotational action of the driving component 40, the separation of juvenile shrimps from broodstock shrimps is realized. The juvenile shrimps swim to the lower part of the separation plate 30 through the separation holes 31, while the broodstock shrimps remain in the separation shell 20; components such as the soft hair bundles 60 and the separation shell 20 in the device provide a good growth environment for the juvenile shrimps, which helps to improve their survival rate.

[0057] When the juvenile shrimp rapid separation device in the embodiment of the present application actually operates, the steps are as follows:

[0058] S1: Place the broodstock shrimps on the placement table 22 of the separation shell 20, and turn on the growth lamp assembly 12 and the oxygen supply assembly 13 to provide a suitable living environment for the juvenile shrimps;

[0059] S2: Start the water circulation mechanism 50, pump the water below the separation plate 30 into the separation shell 20, and spray the water into the upper opening of the separation shell 20 through the water outlet pipe 52 to form a water circulation;

[0060] S3: As the water circulation proceeds, the juvenile shrimps swim in the separation shell 20 and swim to the lower part of the separation plate 30 through the separation holes 31 on the separation plate 30; at the same time, the driving component 40 drives the separation plate 30 to rotate slowly, further promoting the separation of the juvenile shrimps;

[0061] S4: After the juvenile shrimps swim to the lower part of the separation plate 30, the juvenile shrimps can be collected through the collection pipe 11, and the on-off valve on the collection pipe 11 can be opened or closed as needed; in addition, the juvenile shrimps in the housing 10 can also be fished with a fishing net.

[0062] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0063] 1. Through the water circulation and the rotational action of the separation plate 30, the rapid separation of juvenile shrimps from broodstock shrimps is realized, and the separation efficiency is improved;

[0064] 2. Components such as the soft hair bundles 60 and the isolation cover 51 in the device effectively prevent the juvenile shrimps from being injured during the separation process;

[0065] 3. By providing a suitable living environment and good growth conditions, the survival rate of the juvenile shrimps is improved.

[0066] Embodiment 2: In the above embodiment, if there are a large number of juvenile shrimps, the efficiency of simply relying on the juvenile shrimps to separate by swimming is too low and takes a long time; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0067] like Figure 3 As shown, a spiral plate 32 is disposed on the top surface of the separation plate 30 , and the spiral plate 32 is distributed in a spiral from the center to the edge of the separation plate 30 , and the partition shell 20 and the spiral plate 32 are staggered.

[0068] It should be noted that the bottom surface of the partition shell 20 is not lower than the top surface of the spiral plate 32 .

[0069] It should be noted that the number of turns and the pitch of the spiral plate 32 are selected according to actual needs and will not be described in detail here.

[0070] Further, such as Figure 3 As shown, the plurality of separation holes 31 on the separation plate 30 are distributed in a spiral shape along the spiral plate 32 .

[0071] Further, such as Figure 3 As shown, the plurality of soft hair bundles 60 on the separation plate 30 are distributed in a spiral shape along the spiral plate 32 .

[0072] It should be noted that the spiral plate 32 , the separation hole 31 and the soft hair bundle 60 are staggered.

[0073] It should be noted that in this embodiment, the rotation direction of the separation plate 30 is the same as the spiral direction of the spiral plate 32 from outside to inside (both are clockwise or counterclockwise).

[0074] It can be understood that when the water circulation mechanism 50 is working, the water flows through the spiral plate 32 to form a spiral flow. This flow mode not only increases the disturbance of the water flow, but also helps to guide the juvenile shrimp out of the partition shell 20; the rotation of the spiral plate 32 and the spiral flow of the water make it easier for the juvenile shrimp to be guided to the outside of the partition shell 20 during the swimming process, and the separation holes 31 on the separation plate 30 are also distributed along the spiral plate 32, further promoting the separation and swimming of the juvenile shrimp; the spiral distribution of the soft hair bundles 60 provides more places for the juvenile shrimp to play and hide, which helps to improve their survival rate and growth rate; the staggered setting between the spiral plate 32, the separation holes 31 and the soft hair bundles 60 avoids mutual interference and collision, and protects the safety of the juvenile shrimp.

[0075] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0076] 1. The arrangement of the spiral plate 32 and the formation of the spiral flow make it easier for the juvenile shrimp to separate from the separation shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface, thereby improving the separation efficiency;

[0077] 2. The spiral distribution of the soft hair bundles 60 provides more ecological niches and hiding places for juvenile shrimps, helps to construct a more diverse ecological environment, and improves the survival rate and growth rate of juvenile shrimps.

[0078] 3. The number of turns, pitch of the spiral plate 32, the separation holes 31, and the number of soft hair bundles 60 can all be adjusted according to actual needs, enabling the device to adapt to the shrimp farming requirements of different scales and conditions.

[0079] Embodiment 3: After long-term use, the soft hair bundles 60 in the above embodiments may be bent or the like, which is not conducive to the activities of juvenile shrimps such as hiding and affects the activity level of juvenile shrimps. The embodiment of the present application is optimized on the basis of the above embodiments.

[0080] As Figure 1 、 Figure 4 and Figure 5 shown, the juvenile shrimp rapid separation device for shrimp farming in the embodiment of the present application further includes an electromagnet assembly 80 and a plurality of bottom blocks 70, and the bottom blocks 70 are the same in number as and correspond one-to-one with the soft hair bundles 60.

[0081] A plurality of soft hair pores 33 are formed on the separation plate 30, and the soft hair pores 33 are the same in number as and correspond one-to-one with the soft hair bundles 60.

[0082] The soft hair bundles 60 slide through the soft hair pores 33, and the bottom ends of the soft hair bundles 60 are arranged on the bottom blocks 70.

[0083] The bottom blocks 70 are located below the separation plate 30, and a tension spring 71 is arranged between the bottom blocks 70 and the separation plate 30.

[0084] The material of the bottom blocks 70 is ferromagnetic metal.

[0085] Among them, the material of the bottom blocks 70 is iron.

[0086] It should be noted that the soft hair bundles 60 pass through the tension spring 71.

[0087] As Figure 1 shown, the electromagnet assembly 80 is arranged on the inner bottom surface of the housing 10, and the electromagnet assembly 80 is located below the gap between the outer wall of the partition housing 20 and the inner wall of the housing 10.

[0088] It can be understood that when the driving component 40 drives the separation plate 30 to rotate and the electromagnet assembly 80 is energized, the bottom block 70 moves with the separation plate 30, and the electromagnet assembly 80 generates a magnetic attraction to the bottom block 70 moved above it, so that the bottom block 70 drives the soft hair bundle 60 to move downward; by controlling the current size and direction of the electromagnet assembly 80, the strength and direction of the magnetic force can be adjusted, thereby achieving precise control of the lifting and lowering of the soft hair bundle 60; when the bottom block 70 leaves the magnetic force range of the electromagnet assembly 80, the bottom block 70 automatically resets and rises under the pulling force of the tension spring 71, driving the soft hair bundle 60 back to its original position to ensure that the soft hair bundle 60 can maintain a stable posture when not affected by external forces.

[0089] By periodically raising and lowering the soft hair bundle 60, the juvenile shrimps near the soft hair bundle 60 can be driven away, so that the juvenile shrimps can more easily break away from the partition shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface, while making room for the juvenile shrimps behind; during the process of raising and lowering the soft hair bundle 60, the soft hair bundle 60 can be smoothed and some dirt on the soft hair bundle 60 can be removed.

[0090] It should be noted that the magnetic force of the electromagnet assembly 80 is controlled according to actual needs and will not be described in detail here.

[0091] It should be noted that when the bottom block 70 drives the soft hair bundle 60 to move downward, the maximum downward movement height is smaller than the length of the soft hair bundle 60 , so that the soft hair bundle 60 will not escape from the soft hair hole 33 .

[0092] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0093] 1. By adjusting the height of the soft hair bundle 60, a more suitable habitat can be provided for the young shrimps, thereby increasing their activity. At the same time, the soft hair bundle 60 also provides a place for more young shrimps to hide and rest, thereby helping to increase their survival rate and growth rate.

[0094] 2. By periodically raising and lowering the soft hair bundle 60, the young shrimps near the soft hair bundle 60 can be driven away to make room for the young shrimps behind, and at the same time, the young shrimps can more easily escape from the separation shell 20 and swim to the bottom of the separation plate 30 or the liquid surface, thereby improving the separation efficiency;

[0095] 3. The soft hair bundle 60 can be straightened during the lifting process and can also play a certain cleaning role.

[0096] Embodiment 4: In the above embodiment, if there is a lot of dirt on the soft hair bundle 60, it is not possible to effectively remove the dirt by just lifting and lowering. The embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0097] like Figure 6 and Figure 7As shown, an annular sleeve 90 is also provided between the bottom block 70 and the separation plate 30, and the tension spring 71 is located inside the annular sleeve 90.

[0098] The annular sleeve 90 is of a tubular structure. The top end of the annular sleeve 90 is sealingly connected to the separation plate 30, and the bottom end of the annular sleeve 90 is sealingly connected to the bottom block 70.

[0099] Among them, the material of the annular sleeve 90 can be rubber.

[0100] The height of the annular sleeve 90 is not greater than the length of the soft hair bundle 60, so that the soft hair bundle 60 will not come out of the soft hair pores 33.

[0101] It should be noted that the height direction of the annular sleeve 90 is the same as the length direction of the soft hair bundle 60.

[0102] A one-way valve 72 is provided inside the bottom block 70, and the water below the bottom block 70 can flow into the annular sleeve 90 through the one-way valve 72.

[0103] It can be understood that during the downward movement of the bottom block 70, the water below will enter the annular sleeve 90 through the one-way valve 72. During the upward movement of the bottom block 70, part of the water in the annular sleeve 90 is ejected through the soft hair pores 33, which can better drive the juvenile shrimps, increase their activity level, make it easier for the juvenile shrimps to break away from the partition shell 20, and swim below the separation plate 30 or to the liquid surface. Additionally, the ejected water flow can wash away some of the dirt on the soft hair bundle 60, playing a certain cleaning role.

[0104] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages:

[0105] 1. The setting of the annular sleeve 90 effectively extends the service life of the tension spring 71 and the soft hair bundle 60, reduces the replacement cost, and at the same time better fixes and protects the tension spring 71, enhancing the stability and reliability of the device;

[0106] 2. By adjusting the electromagnet assembly 80 and the one-way valve 72, the height of the soft hair bundle 60 can be more precisely controlled, providing more suitable habitat and growth conditions for the juvenile shrimps;

[0107] 3. The water flow ejected during the lifting and lowering of the bottom block 70 can better drive the juvenile shrimps, increase their activity level, make it easier for the juvenile shrimps to break away from the partition shell 20, and swim below the separation plate 30 or to the liquid surface;

[0108] 4. The water flow ejected during the lifting and lowering of the bottom block 70 can play a certain cleaning role on the soft hair bundle 60, providing more suitable habitat and growth conditions for the juvenile shrimps.

[0109] In summary, the present application achieves the technical effects of being able to effectively separate juvenile shrimps from broodstock shrimps, reducing the separation time, and improving the survival rate of juvenile shrimps.

[0110] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
