Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a wild breeding device for swimming crabs. Background Art

[0002] Swimming crab (Panthera tricolor) is one of the important aquatic products in my country. It is deeply loved by the public because of its delicious meat and rich nutrition. However, with the serious decline of the resources of swimming crab (Panthera tricolor), swimming crab (Panthera tricolor) has now become the main species for reproduction and release along the coast of my country. In this context, it is particularly important to domesticate swimming crab (Panthera tricolor). By simulating the living conditions in the natural environment, crabs originally raised in an artificial environment can gradually adapt to survival in the wild before release, which can improve environmental adaptability and survival ability. This process can provide new ideas and methods for the protection and development and utilization of the germplasm resources of swimming crab (Panthera tricolor).

[0003] To solve the above technical problems, crabs need to be wild-bred to facilitate their subsequent breeding or survival. In the prior art, for example, Korean patent KR1020230125472A discloses a circulating filtration high-density aquaculture module containing a functional aquaculture tank. The invention realizes a high-density aquaculture habitat through a functional aquaculture tank, and achieves a heat preservation effect by using a refrigerated container shell, so that thermal efficiency can be achieved with only a ready-made low-capacity heat exchanger, and the biological filter tank can be effectively recycled. It is a high-processing circulating filtration aquaculture container module that realizes an independent ecosystem through unitization, miniaturization, standardization, miniaturization and configuration, and is installed in a container, but the device has a large room for improvement in how to wild biological habits. Summary of the invention

[0004] The purpose of the present invention is to provide a wild breeding device for swimming crabs, which can simulate the living environment of wild breeding crabs. The simulation device can continue the simulation for a long time and the simulation situation is accurate. In this way, the swimming crabs that have undergone simulated survival can adapt to the wild environment more quickly and improve their survival rate after being released.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: a wild breeding device for swimming crabs, comprising a first matrix capable of accommodating biological activities, the first matrix having an inlet plate for feeding a medium into the interior, and the first matrix having a guide plate capable of swinging up and down, the guide plate being arranged in the outflow direction of the inlet plate.

[0006] The inlet plate is connected to the external water pump, and the multi-mode water inlet is realized by controlling the inlet mode of the inlet plate. The specific modes are: continuous water discharge drop by drop, uninterrupted strong and powerful water discharge, continuous and small water flow discharge, and water flow forming a water column. The oxygen content in the water is increased during the water discharge process. By inletting water at a variety of flow rates, the oxygen content inside the first matrix is ​​changed to simulate the top flow movement of the swimming crab. A guide plate is further arranged on one side of the inlet plate. The guide plate can automatically adjust the swing angle according to demand, and the swing of the guide plate can also be controlled in conjunction with the water inlet of the inlet plate. The swinging guide plate can change the direction of the water flowing into the inlet plate, and the angle of the swimming crab facing the incoming water flow will change, which can increase the amount of exercise of the swimming crab and train the crab's movement speed in the water to make it wild. More importantly, the cooperation of the guide plate and the inlet plate can form water inflow at different angles inside the first matrix, which can avoid the accumulation of dirt inside the first matrix and promote the movement of the internal dirt to facilitate collection and discharge.

[0007] According to one embodiment of the present invention, a wave-pushing plate is provided in the first substrate, and the wave-pushing plate is arranged opposite to the inlet plate and the guide plate. The arrangement of the wave-pushing plate is used to control the wave flow inside the first substrate, simulate the water waves in the wild, and make the crabs adapt to the wild environment. In addition, the wave-pushing plate is arranged separately from the inlet plate to avoid working interference between the two.

[0008] According to one embodiment of the present invention, the upper part of the first base is connected to two parallel first plates through a first tube, a first rod is connected between the first plates, a second plate that can slide relative to the first rod is provided on the first rod, a first hydraulic rod is connected to the second plate, and a chain is connected to the second plate. The dragging friction of the iron chain connected to the sliding second plate in the water flow is used to simulate the predation state of the swimming crab's natural enemy, improve the swimming crab's anti-predation alert avoidance ability, and increase the survival rate of the swimming crab after being released into the wild.

[0009] According to one embodiment of the present invention, the bottom of the guide plate is hinged to the first base, the bottom surface of the guide plate is connected to a second hydraulic rod hinged thereto, a slider is provided at the bottom of the second hydraulic rod, a slide rail is provided below the slider, and the sliding direction of the slider is consistent with the inflow direction of the inflow plate.

The swing plate provided can control the height range of the liquid flow water layer guided by the guide plate. For example, the water flow formed by the guide plate flows on the surface of the first matrix, and the swing plate provided can reduce the probability of the water body flowing downward in the first matrix, so as to achieve precise control of the water inlet height, simulate water inlet at different height layers, and the swing plate can swing according to the impact force of the water body, which can help to remove sediments around the swing plate and the second hydraulic rod and drive crabs around them away.

[0011] According to one embodiment of the present invention, a collecting piece is provided at the bottom of the first substrate, and the collecting piece has a collecting sleeve nested with the first substrate. The bottom of the collecting sleeve passes through the first substrate and is connected to a second collecting tube, and the diameter of the upper end of the collecting sleeve is greater than the diameter of the lower end thereof. A mounting ring connected to the outer end of the collecting sleeve is provided, and the mounting ring is fixedly connected to the first substrate. The collecting piece is provided at the bottom of the first substrate to collect waste generated by aquaculture inside the first substrate, and an external pump body provides suction force to the second collecting tube, thereby forming a suction force in the collecting piece to suck the waste, and the upper and lower end diameters of the collecting sleeve are improved and designed to prevent organisms from being sucked into the second collecting tube, thereby ensuring the quality of aquaculture water inside the first substrate and preventing the death of organisms or damage to their limbs. In addition, the suction method can simulate the situation where crabs encounter predators at the bottom of the water area, and train crabs to respond to predators.

[0012] According to one embodiment of the present invention, a first ring body is placed inside the collecting sleeve, the first ring body is connected to at least two elastic plates at the bottom, the inner side of the first ring body is provided with a second ring body coaxial with the first ring body and having a gap therebetween, the inner side of the second ring body is provided with a third ring body coaxial with the first ring body and having a gap therebetween, the first ring body, the second ring body and the third ring body are connected by connecting rods or elastic rods, and the inner space of the collecting sleeve can be filled by arranging the first ring body, the second ring body and the third ring body at intervals, so as to avoid or prevent crabs from being sucked into the collecting sleeve due to the difficulty in resisting the suction force, The first ring body, the second ring body and the third ring body are arranged separately to help divide the sucked dirt, which can speed up the sewage discharge and avoid the problem of dirt blockage. The setting of the elastic plate makes it convenient to take out the first ring body, the second ring body and the third ring body, and the elastic deformation of the elastic plate can also be used to loosen the dirt collected in the collection sleeve. More importantly, the first ring body, the second ring body and the third ring body can separate the suction force and suction direction of the second collection tube, prevent or avoid excessive suction force at a local position, and achieve the effect of controlling the suction range and suction force.

[0013] According to one embodiment of the present invention, a lamp body is provided above the first substrate to provide lighting, simulating day and night in a natural environment so that crabs can develop normal work and rest habits. Of course, the illumination intensity of the lamp body can also be changed to simulate the lighting of ships traveling on the water.

[0014] According to one embodiment of the present invention, a first partition is provided in the first substrate, and the first partition can separate the internal space of the first substrate into a first space for accommodating biological activities and a second space for placing items. The first partition can be provided to separate the internal space of the first substrate, so as to divide the breeding space and the equipment placement space, and a reciprocating motor or a wave maker is placed in the equipment placement space, and a box cover is provided above the placement space to cover the top of the placement space to prevent water from entering.

[0015] According to one embodiment of the present invention, the first matrix has a second matrix built in, the second matrix has a space that can accommodate the entry and exit of organisms, and the first matrix is ​​also provided with a third matrix, which can block the flow of fluid. The second matrix and the third matrix can be formed by concrete casting, and the second matrix and the third matrix both have a space that can accommodate the entry and exit of organisms, especially a space for accommodating the entry and exit of swimming crabs. In this way, spatial heterogeneity is used to simulate the multi-reef environment of the seabed in the wild, providing a hiding place for swimming crabs, so that swimming crabs can adapt to the wild environment more quickly after being released, and by arranging the second matrix and the third matrix inside the first matrix, it is possible to use the two to interfere with the water body inside the first matrix, especially to interfere with the water flow passing through the second matrix and the third matrix, so as to simulate the change of the water flow interference outside the swimming crab hiding space in the natural environment, so that the swimming crabs can adapt as soon as possible and reduce their stress response. In addition, the second substrate and the third substrate are arranged inside the first substrate to interfere with the flow of water at the bottom of the first substrate, which is conducive to the accumulation of sediment at the bottom of the first substrate and helps the sediment to be collected by the collector to keep the water in the first substrate clean.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the oxygen content inside the first matrix is ​​changed by inletting water at a variety of flow rates to simulate the top flow movement of the swimming crab; a guide plate is further arranged on one side of the inlet plate; the guide plate can automatically adjust the swing angle according to demand, and the swing of the guide plate can also be controlled in conjunction with the inlet of the inlet plate, so that the swinging guide plate can change the direction of the water body flowing into the inlet plate, and the angle of the swimming crab facing the inlet water flow will change, which can increase the amount of exercise of the swimming crab and train the crab's movement speed in the water to make it wild; more importantly, through the cooperation of the guide plate and the inlet plate, water can be inletted at different angles into the first matrix, which can avoid the accumulation of dirt inside the first matrix and promote the movement of the internal dirt to facilitate collection and discharge.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] Embodiment 1 like Figure 1-Figure 8 As shown, the wild breeding device for swimming crabs three tubers includes a first matrix 10 that can accommodate biological activities. The first matrix 10 has an inlet plate 40 for feeding the medium into the interior. The first matrix 10 has a guide plate 50 that can swing up and down. The guide plate 50 is arranged in the outflow direction of the inlet plate 40.

[0023] The inlet plate 40 is connected to an external water pump, and multi-mode water inlet is achieved by controlling the inlet mode of the inlet plate 40, and the specific modes are: continuous water discharge drop by drop, uninterrupted strong and powerful water discharge, continuous and fine water flow discharge, and water flow forming a water column. The oxygen content in the water is increased during the water discharge process. By inletting water at a variety of flow rates, the oxygen content inside the first matrix 10 is changed to simulate the top flow movement of the swimming crab. Further, a guide plate 50 is provided on one side of the inlet plate 40. The guide plate 50 can automatically adjust the swing angle according to demand, and can also cooperate with the inlet water of the inlet plate 40 to control the swing of the guide plate 50. The swinging guide plate 50 can change the direction of the water flowing into the inlet plate 40, and the angle of the swimming crab facing the incoming water flow will change, which can increase the amount of exercise of the swimming crab and train the crab's movement speed in the water to make it wild. More importantly, the cooperation of the guide plate 50 and the inlet plate 40 can form water inflow at different angles inside the first matrix 10, which can avoid the accumulation of dirt inside the first matrix 10 and promote the movement of the internal dirt to facilitate collection and discharge.

[0024] The first substrate 10 has a wave-pushing plate 20 disposed in opposition to the inlet plate 40 and the guide plate 50. The wave-pushing plate 20 is used to control the wave flow inside the first substrate 10, simulate the water waves in the wild, and make the crabs adapt to the wild environment. In addition, the wave-pushing plate 20 is disposed separately from the inlet plate 40 to avoid interference between the two in their work.

[0025] The upper part of the first base 10 is connected to two parallel first plates 30 through the first tube 13, the first plates 30 are connected with a first rod 31, the first rod 31 is provided with a second plate 32 that can slide relative to the first rod 31, the second plate 32 is connected with a first hydraulic rod 33, and the second plate 32 is connected with a chain. The dragging friction of the iron chain connected to the sliding second plate 32 in the water flow is used to simulate the predation state of the swimming crab's natural enemy, improve the swimming crab's anti-predation alert avoidance ability, and increase the survival rate of the swimming crab after being released into the wild.

[0026] The bottom of the guide plate 50 is hinged to the first base 10, and the bottom surface of the guide plate 50 is connected to a second hydraulic rod 51 hinged thereto, a slider 53 is provided at the bottom of the second hydraulic rod 51, and a slide rail 54 is provided below the slider 53, and the sliding direction of the slider 53 is consistent with the inflow direction of the inflow plate 40. The second hydraulic rod 51 can control the tilt angle range of the guide plate 50 connected to the upper part by sliding.

[0027] The telescopic rod part of the second hydraulic rod 51 is provided with a connecting block that can be synchronously telescoped therewith, and a swinging plate 52 that can tilt and swing is hinged on one side of the bottom of the second hydraulic rod 51, and the end of the swinging plate 52 is connected to the connecting block through an elastic member. The swinging plate 52 can control the height range of the liquid flowing water layer guided by the guide plate 50. For example, the water flow formed by the guide plate 50 flows on the surface of the first matrix 10. The swinging plate 52 can reduce the probability of the water body flowing downward into the first matrix 10, so as to achieve precise control of the water inlet height and simulate water inlet at different height layers. The swinging plate 52 can swing according to the impact force of the water body, which helps to remove the sediment around the swinging plate 52 and the second hydraulic rod 51 and drive the crabs around them away.

[0028] A collecting member 60 is provided at the bottom of the first substrate 10. The collecting member 60 has a collecting sleeve 62 nested with the first substrate 10. The bottom of the collecting sleeve 62 passes through the first substrate 10 and is connected to a second collecting tube 61. The diameter of the upper end of the collecting sleeve 62 is greater than the diameter of the lower end. A mounting ring 63 connected to the collecting sleeve 62 is provided at the outer end, and the mounting ring 63 is fixed to the first substrate 10. The collecting member 60 is provided at the bottom of the first substrate 10 to collect the waste generated by the aquaculture inside the first substrate 10. The external pump body provides suction force to the second collecting tube 61, and then forms a suction force in the collecting member 60 to suck the waste. The upper and lower diameters of the collecting sleeve 62 are improved and designed to prevent the organisms from being sucked into the second collecting tube 61. In this way, the aquaculture water quality inside the first substrate 10 is ensured and the death or damage of the limbs of the organisms is prevented. In addition, the suction method can simulate the situation where crabs encounter predators at the bottom of the water area, and train the crabs to respond to predators.

[0029] A first ring body 65 is placed inside the collecting sleeve 62. The first ring body 65 is connected to at least two elastic plates 64 at the bottom. A second ring body 66 coaxial with the first ring body 65 and having a gap therebetween is provided inside the first ring body 65. A third ring body 67 coaxial with the second ring body 66 and having a gap therebetween is provided inside the second ring body 66. The first ring body 65, the second ring body 66 and the third ring body 67 are connected by connecting rods or elastic rods. The first ring body 65, the second ring body 66 and the third ring body 67 are arranged at intervals to fill the internal space of the collecting sleeve 62, thereby avoiding or preventing crabs from being sucked into the collecting sleeve 62 and being unable to resist the suction force and crawling out of the collecting sleeve 62. The first ring body 65, the second ring body 66 and the third ring body 67 arranged at intervals are helpful to divide the sucked dirt, which can speed up the sewage discharge and avoid the problem of sewage discharge blockage. The setting of the elastic plate 64 is convenient for taking out the first ring body 65, the second ring body 66 and the third ring body 67, and the elastic deformation of the elastic plate 64 can also be used to loosen the dirt collected in the collection sleeve 62. More importantly, the first ring body 65, the second ring body 66 and the third ring body 67 can separate the suction force and suction direction of the second collection tube 61, prevent or avoid excessive suction force at a local position, thereby achieving the effect of controlling the suction range and suction force.

[0030] A lamp body 16 is provided above the first substrate 10 for providing lighting to simulate the day and night in the natural environment so that crabs can develop normal work and rest habits. Of course, the illumination intensity of the lamp body 16 can also be changed to simulate the lighting of ships traveling on the water.

[0031] A first partition 12 is provided in the first substrate 10, and the first partition 12 can separate the internal space of the first substrate 10 into a first space for accommodating biological activities and a second space for placing items. The first partition 12 can be provided to separate the internal space of the first substrate 10, so as to divide the breeding space and the equipment placement space, and the reciprocating motor or wave maker is placed in the equipment placement space. Of course, a box cover 11 is provided above the placement space to cover the top of the placement space to prevent water from entering.

[0032] The first substrate 10 has a second substrate 14 built in, and the second substrate 14 has a space that can accommodate the entry and exit of organisms. The first substrate 10 also has a third substrate 15 inside, and the third substrate 15 can block the flow of fluid. The second substrate 14 and the third substrate 15 can be formed by concrete casting. The second substrate 14 and the third substrate 15 can have a space that can accommodate the entry and exit of organisms, especially a space for accommodating the entry and exit of swimming crabs. In this way, spatial heterogeneity is used to simulate the multi-reef environment of the seabed in the wild, providing a hiding place for swimming crabs, so that swimming crabs can adapt to the wild environment more quickly after being released, and by arranging the second substrate 14 and the third substrate 15 inside the first substrate 10, the two can be used to interfere with the water body inside the first substrate 10, especially to interfere with the water flow passing through the second substrate 14 and the third substrate 15, so as to simulate the water flow outside the hiding space of swimming crabs in the natural environment, causing interference to form changes, so that swimming crabs can adapt as soon as possible and reduce their stress response. In addition, the second substrate 14 and the third substrate 15 are arranged inside the first substrate 10 to disturb the flow of water at the bottom of the first substrate 10, which is beneficial to disturb the bottom sediment in the first substrate 10 and helps to promote the sediment to be collected by the collecting member 60 to keep the water quality in the first substrate 10 clean.

[0033] Embodiment 2: See attached Figure 4-Figure 7 As shown, this embodiment is further developed on the basis of the solution of embodiment 1, in which an aeration assembly 70 is provided on the side of the inlet plate 41, and the aeration assembly 70 has a first mounting plate 71 fixed to the side wall of the first substrate 10, a second mounting plate 73 is provided at the bottom of the first mounting plate 71, and at least two aeration columns 72 are arranged above the second mounting plate 73, the aeration column 72 is a columnar structure, hollow inside, and aeration holes are evenly distributed on the surface of the aeration column 72, an aeration pipe 76 is connected to one side of the second mounting plate 73, and the second mounting plate 73 has a channel connected to the aeration column 72, and the channel is connected to the aeration pipe 76, so that the gas input by the aeration pipe 76 can enter the aeration house 72 through the channel. A plurality of aeration columns 72 are provided to aerate the interior of the first substrate 10 to ensure the oxygen content of the aquaculture water and prevent the crabs from dying of lack of oxygen during the wilding period. An aeration pipe 76 is connected to an external aeration pump to achieve uninterrupted aeration or aeration based on the oxygen content detection result inside the first substrate 10. An oxygen content sensor is provided in the first substrate 10. This is a prior art and will not be elaborated on here.

[0034] A guide member 75 is provided inside the aeration column 72. The guide member 75 has a guide base ring 752 with an annular structure. The center of gravity of the guide base ring 752 is connected to a rotating shaft 753 through a connecting rod. The rotating shaft 753 can rotate. Guide blades 751 are arranged around the rotating shaft 753. An extension block 754 is provided on the outer side of the guide base ring 752.

[0035] The method of arranging the guide member 75 inside the aeration column 72 is used to achieve different ranges of discharge of the aeration airflow from each aeration column 72, so as to avoid uneven distribution of oxygen content in aeration at the same height area. Specifically, the upward impact height range of the airflow flowing upward from the bottom of the aeration column 72 is controlled by the rotation of the guide member's rotating shaft 753 and the guide blade 751, so that most of the airflow is discharged from the aeration holes of the aeration column 72 below the guide member 75, and part of the airflow is discharged from the side aeration holes of the aeration column 72 above the guide member 75 after passing through the rotating shaft 753 and the guide blade 751, so as to avoid uneven distribution of oxygen content in aeration at the same height area. In addition, the method of arranging the extension block 754 on the outside of the guide base ring 752 can avoid or reduce the possibility of deformation of the aeration column 72 due to excessive collision frequency between the guide base ring 752 and the inner wall of the aeration column 72.

[0036] A check piece 74 is provided at the connection between the channel of the second mounting plate 73 and the aeration column 72. The check piece 74 includes a first sleeve 742 which is interference fit or overfit with the channel. The bottom of the first sleeve 742 has a threaded connection with the aeration pipe 76. A plurality of spaced and coaxial rubber blocks 745 are provided in the first sleeve 742. A rubber column 744 is provided at the center of the first sleeve 742. The center of the rubber column 744 has a channel connecting the two ends of the first sleeve 742, and the inlet end of the channel has a conical surface. The outlet end of the channel has a ring sleeve 743, and the ring sleeve 743 also has a sealing plate which can block the channel, and the sealing plate can swing.

[0037] The sealing plate on the ring sleeve 743 of the anti-return member 74 can prevent the water in the aeration column 72 from flowing out in the opposite direction, and the rubber column 744 can deform its channel according to the aeration airflow pressure and the deformable characteristic of the rubber column 744 during aeration, thereby changing the corresponding air outlet flow rate and concentrating the airflow to be discharged upward to interact with the guide member 75, which has an impact and extrapolation effect on impurities that may exist in the aeration column 72, thereby prompting the impurities to be discharged from the aeration column 72.

[0038] The outlet end of the first sleeve 742 is connected to a first cover 741 . The first cover 741 can restrict the rubber block 745 inside the first sleeve 742 . The first sleeve 742 has a ball 746 in contact with the rubber block 745 .

[0039] The design of the ball 746 can make the rubber block 745 produce corresponding rotational motion, thereby preventing the rubber block 745 from deforming too much and squeezing the inner wall of the first sleeve 742 excessively, causing deformation of the first sleeve 742 or excessive deformation of the rubber block 745 .
