Description

Technical Field

[0001] This invention relates to the field of aquaculture, specifically to a non-destructive transfer device and method for ribbonfish. Background Technology

[0002] Ribbonfish, also known as hairtail, oil ribbonfish, and toothed ribbonfish, is a ferocious fish with a wide distribution, fast growth, and high yield. It is an important marine economic fish species in my country with huge market demand. However, due to long-term overfishing, ribbonfish resources have declined. Therefore, the live capture and damage-free transportation of wild ribbonfish juveniles are important prerequisites for carrying out artificial domestication and breeding.

[0003] Traditional methods of transferring live fish into ponds typically involve manual labor, where the fish are transported from the aquaculture tank to a designated location and then scooped out with a net and placed into the pond. However, ribbonfish are highly stress-prone fish, highly sensitive to their environment, and exhibit strong stress responses, easily triggering behaviors such as self-harm and collisions. Therefore, traditional transfer methods are not only time-consuming and labor-intensive, but also inefficient, and can easily cause stress, damage the fry, and result in low survival rates after being placed in the pond. This approach is not suitable for highly stress-prone fish.

[0004] Furthermore, to improve the efficiency of live fish transfer and reduce labor intensity, some inventors have designed automatic fish fry transfer devices. For example, patent application number CN202311053709, entitled "A Fully Automatic Rapid Transport System for Fish Fry Entering the Hold of an Aquaculture Vessel," uses hydraulic cylinders and lifting plates to control the raising of the fish storage tank, while simultaneously using a tipping mechanism to dump the fish into the pond. Although this device can ensure the speed of fish release, it cannot guarantee that all fish can be successfully dumped onto the slide rail, and the dumping method is not suitable for highly stressful fish, easily causing stress, damaging the fry, and resulting in a low survival rate after entering the pond. Summary of the Invention

[0005] The purpose of this invention is to provide a non-destructive transport device and method for ribbonfish that is not only easy to operate, but also reduces stress, effectively avoids mechanical damage to fish fry during transport, and improves the survival rate of fish fry after they are introduced into the pond.

[0006] The technical solution of this invention is:

[0007] A device for the non-destructive transfer of ribbonfish, comprising:

[0008] Transfer cart;

[0009] The temporary holding box is mounted on a transport trolley. The upper side wall of the temporary holding box has a fish outlet, and the fish outlet has an openable sealing cap.

[0010] An air bag and an inflating device, the air bag is located in the temporary rearing box and fixed on the inner bottom surface of the temporary rearing box, the air bag is provided with an inflating port, and the inflating device is communicated with the inflating port through an inflating pipeline. The specific use of the present application is as follows,

[0011] The live fish non-damage transfer device is moved to a designated position by a transfer trolley, and the fish outlet is opened; then, the pool entry slide rail is connected, the pool entry slide rail is distributed in an inclined manner, the upper end of the pool entry slide rail is connected with the fish outlet, and the lower end of the pool entry slide rail is connected with the fish tank; then, the inflating device is started, air is filled into the air bag, the air bag is inflated, the water in the temporary rearing box and the juvenile fish are lifted together, when the water in the temporary rearing box reaches the fish outlet position, the water in the temporary rearing box and the juvenile fish are unloaded into the fish tank through the fish outlet and the pool entry slide rail. Since the live fish non-damage transfer device adopts the air bag inflation mode to lift the water body and the juvenile fish, the juvenile fish spontaneously flows with the water in the temporary rearing box through the fish outlet and the pool entry slide rail and is unloaded into the fish tank, so that the stress level can be reduced, mechanical damage caused by the juvenile fish in the transfer process can be effectively avoided, and the survival rate of the juvenile fish after entering the fish tank can be improved. On the other hand, during the process of starting the inflating device, filling air into the air bag, and inflating the air bag, the operator can also adjust the inflation rate of the air bag according to the performance of the juvenile fish in the box, so as to further control and reduce the stress behavior of the juvenile fish and improve the survival rate of the juvenile fish after entering the fish tank. Therefore, compared with the live fish transfer method in the prior art, the transfer method using the live fish non-damage transfer device has the advantages of convenient operation, high transfer rate, reduced stress level, effectively avoiding mechanical damage of the juvenile fish in the transfer process, and improved survival rate of the juvenile fish after entering the fish tank.

[0012] As preferred, the linkage valve body is further connected to the inflation pipeline to control the opening and closing of the inflation pipeline, and the linkage valve body is linked to the sealing cover and closed when the sealing cover is closed, and opened when the sealing cover is opened. In the process of transporting the device, the sealing cover on the fish outlet is removed and the fish outlet is opened before the air bag is inflated and the air bag is inflated. However, in actual operation, the operator may forget to open the sealing cover and directly open the inflation device to inflate the air bag, causing the water in the temporary tank to overflow through the upper port of the temporary tank instead of flowing out through the fish outlet, causing serious stress behavior of the juvenile ribbonfish, causing self-injury, impact and other behaviors, and even causing the juvenile ribbonfish to escape from the temporary tank. In order to solve this problem, the present application provides a linkage valve body on the inflation pipeline, which is linked to the sealing cover. When the sealing cover is closed, the linkage valve body is closed; when the sealing cover is opened, the linkage valve body is opened; in this way, without affecting the normal use of the device, the problem of the operator forgetting to open the sealing cover and directly opening the inflation device to inflate the air bag, causing the water in the temporary tank to overflow through the upper port of the temporary tank instead of flowing out through the fish outlet, causing serious stress behavior of the juvenile ribbonfish, causing self-injury, impact and other behaviors, and even causing the juvenile ribbonfish to escape from the temporary tank.

[0013] As preferred, the linkage valve body comprises:

[0014] A valve cavity is provided with a piston, and the piston is connected to a piston rod;

[0016] A linkage rod is connected to the piston rod;

[0017] When the sealing cover is closed, the linkage rod abuts against the sealing cover, the piston is located between the front and rear interfaces, and the linkage rod restricts the movement of the piston to the rear interface. In this way, after the sealing cover is closed, the linkage rod is linked to the sealing cover to drive the piston to move between the front and rear interfaces, and the linkage rod restricts the movement of the piston to the rear interface, thereby closing the linkage valve body. At this time, even if the inflation device is opened, the gas cannot enter the air bag through the inflation pipeline, thereby preventing the air bag from inflating. When the sealing cover is opened, the movement of the piston is not restricted by the linkage rod, so that after the inflation device is opened, the gas enters the valve cavity through the front pipeline and the front interface, then pushes the piston to move to the rear interface, and makes the front interface and the rear interface communicate, thereby making the gas enter the air bag through the rear pipeline, thereby inflating the air bag, without affecting the normal use of the device.

[0018] As preferred, a limiting block is arranged on the inner wall of the valve cavity, the limiting block is located between the front interface and the rear interface, and the piston and the rear interface are located on the same side of the limiting block. In this way, the piston can be prevented from moving to the front interface side of the valve cavity and passing through the front interface, so that the front interface is located between the piston and the rear interface, and the normal work of the linkage valve body is affected.

[0019] As preferred, an upper frame is further included, the upper frame is matched with the inner cavity of the temporary breeding box body and can move up and down along the inner cavity of the temporary breeding box body, the upper frame is located above the air bag, and the upper frame is fixedly connected with the top of the air bag. In this way, during the inflation of the air bag, the upper frame will move upwards along the inner cavity of the temporary breeding box body, and the air bag is shaped through the upper frame, so as to prevent the air bag from being clamped with the side wall of the box during inflation, and further to avoid the situation that the ribbon fish larvae are clamped in the gap.

[0020] As preferred, a lower frame is further included, the lower frame is connected at the bottom of the air bag, and the lower frame is fixedly connected with the inner bottom surface of the temporary breeding box body. In this way, the air bag can be fixed on the inner bottom surface of the temporary breeding box body through the lower frame, so as to facilitate the installation and disassembly of the air bag.

[0021] As preferred, the fish outlet is formed by extending the side wall of the temporary breeding box body outward. In this way, when the in-pool slide rail is connected, it is beneficial to connect the fish outlet at the upper end of the in-pool slide rail.

[0022] As preferred, the fish outlet is formed by extending the side wall of the temporary breeding box body outward. In this way, when the in-pool slide rail is connected, it is beneficial to connect the fish outlet at the upper end of the in-pool slide rail.

[0023] As preferred, the top of the temporary breeding box body is provided with a detachably connected box cover. In this way, it is convenient to put the ribbon fish larvae and water into the temporary breeding box body.

[0024] As preferred, the inflation device is arranged on the transfer trolley outside the temporary breeding box body.

[0028] Third, open the inflator, inflate the air bag, and make the air bag expand, so as to lift the water and the juvenile fish in the temporary cultivation box, and when the water in the temporary cultivation box reaches the fish outlet position, the water and the juvenile fish in the temporary cultivation box are unloaded into the fish pool through the fish outlet and the pool entry slide. Since the juvenile fish transfer method using the juvenile fish non-damage transfer device adopts the air bag expansion mode to lift the water body and the juvenile fish, the juvenile fish spontaneously flows out of the fish outlet and the pool entry slide together with the water in the temporary cultivation box, so that the stress level can be reduced, mechanical damage caused by the juvenile fish during the transfer process can be effectively avoided, and the survival rate of the juvenile fish after entering the pool can be improved. On the other hand, during the process of opening the inflator, inflating the air bag, and making the air bag expand, the operator can also adjust the air bag expansion rate according to the performance of the juvenile fish in the box, so as to further control and reduce the stress behavior of the juvenile fish and improve the survival rate of the juvenile fish after entering the pool.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0044] Specific Implementation Example 1, such as Figure 1 As shown, a non-destructive transfer device for ribbonfish includes a transfer trolley 1, a temporary holding box 2, an airbag 3, and an inflation device 4. The temporary holding box 2 is mounted on the transfer trolley 1. A fish outlet 6 is located on the upper part of the side wall of the temporary holding box 2. An openable sealing cover 7 is provided on the fish outlet 6. The sealing cover 7 is used to seal the fish outlet 6. The airbag 3 is located inside the temporary holding box 2 and fixed to the inner bottom surface of the temporary holding box 2. An inflation port is provided on the airbag 3. The inflation device 4 is connected to the inflation port through an inflation pipe. The inflation device 4 is an air pump or a blower.

[0045] The specific use of the ribbonfish non-destructive transfer device in this embodiment is as follows.

[0046] A non-destructive ribbonfish transfer device is moved to a designated location using a transfer trolley 1, and the fish outlet 6 is opened. Next, an inlet rail is connected; the inlet rail is inclined, with its upper end connected to the fish outlet 6 and its lower end connected to the rearing pond. Then, the inflation device 4 is activated, inflating the air bladder 3, which lifts the water and ribbonfish fry from the temporary holding tank 2. Once the water in the temporary holding tank 2 reaches the fish outlet 6, the water and ribbonfish fry are discharged into the fish pond through the fish outlet 6 and the inlet rail. Because this non-destructive ribbonfish transfer device uses the inflation of the air bladder 3 to lift the water and ribbonfish fry, allowing the fry to spontaneously flow with the water in the temporary holding tank 2 through the fish outlet 6 and the inlet rail into the fish pond, stress levels are reduced, mechanical damage to the fry during transfer is effectively avoided, and the survival rate of the fry after they enter the pond is improved. On the other hand, during the inflation process of the airbag 3, which is inflated by activating the inflation device 4, the operator can adjust the inflation rate of the airbag 3 based on the behavior of the juvenile ribbonfish in the tank. This further controls and reduces stress behavior in the ribbonfish, improving the survival rate of the fry after they are introduced into the pond. Therefore, compared with existing methods of transferring live fish into the pond, the method using this non-destructive ribbonfish transfer device is convenient to operate, can quickly transfer juvenile ribbonfish to the pond, has a high transfer rate, reduces stress, effectively avoids mechanical damage to the fry during transfer, and improves the survival rate of the fry after they are introduced into the pond.

[0047] In a second embodiment, as shown in the drawings, a device for non-destructive transportation of ribbonfish larvae includes a transportation trolley 1, a temporary breeding box 2, an air bag 3 and an air filling device 4. The temporary breeding box 2 is arranged on the transportation trolley 1. The temporary breeding box 2 is provided with a fish outlet 6 at the upper part of the side wall. The fish outlet 6 is provided with an openable sealing cover 7. The sealing cover 7 is used to seal the fish outlet 6. In this embodiment, one side of the sealing cover 7 is hinged to the left side or right side of the fish outlet 6, and the sealing cover 7 is connected to the fish outlet 6 by buckling. Of course, the sealing cover 7 can also be screwed onto the fish outlet 6, or the sealing cover 7 can be directly buckled onto the fish outlet 6. Figure 1

[0048] The air bag 3 is located in the temporary breeding box 2 and is fixed to the inner bottom surface of the temporary breeding box 2. The air bag 3 is provided with an air filling port. The air filling device 4 is in communication with the air filling port through an air filling pipeline. In this embodiment, the air filling device 4 is arranged on the transportation trolley 1 outside the temporary breeding box 2. The air filling device 4 is a gas pump or a blower.

[0049] Specifically, the temporary breeding box 2 is open at the top. The top of the temporary breeding box 2 is provided with a detachable box cover 5. In this way, it is convenient to put ribbonfish larvae and water into the temporary breeding box 2. In this embodiment, the air bag 3 is also provided with an exhaust valve, which is located outside the temporary breeding box 2, and the gas in the air bag 3 is released through the exhaust valve.

[0050] Further, the fish outlet 6 extends outwardly from the side wall of the temporary breeding box 2 to form a fish outlet pipe 6.1, and the sealing cover 7 is arranged at the end of the fish outlet pipe 6.1. In this way, when connected to the pool slide rail, it is beneficial to connect the fish outlet 6 to the upper end of the pool slide rail.

[0051] Further, the fish outlet pipe 6.1 and the side wall of the temporary breeding box 2 are connected by a circular arc transition. In this way, during the transportation of ribbonfish larvae into the pool, when the ribbonfish larvae pass through the fish outlet pipe 6.1, the mechanical damage to the surface of the ribbonfish larvae can be further reduced.

[0052] Further, the device for non-destructive transportation of ribbonfish larvae also includes an upper frame, which matches the inner cavity of the temporary breeding box 2 and can move up and down along the inner cavity of the temporary breeding box 2. The upper frame is located above the air bag 3, and the upper frame is fixedly connected to the top of the air bag 3. In this way, during the expansion of the air bag 3, the upper frame will move upward along the inner cavity of the temporary breeding box 2, and the air bag 3 will be shaped by the upper frame, preventing the air bag 3 from being pinched by the side wall of the box when it expands, thereby avoiding the situation that the ribbonfish larvae are stuck in the gap.

[0053] ​Further, the band fish non-damage transfer device further comprises a lower frame. The lower frame is connected at the bottom of the air bag 3, and the lower frame is fixedly connected with the inner bottom surface of the temporary breeding box 2. In the embodiment, the lower frame is connected with the inner bottom surface of the temporary breeding box 2 through bolts. In this way, the air bag 3 can be fixed on the inner bottom surface of the temporary breeding box 2 through the lower frame, so as to facilitate the installation and disassembly of the air bag 3.

[0054] The specific use of the band fish non-damage transfer device in the embodiment is as follows,

[0055] The band fish non-damage transfer device is moved to a designated position by the transfer trolley 1, and the fish outlet 6 is opened; then, the pool entry slide rail is connected, the pool entry slide rail is distributed in an inclined manner, the upper end of the pool entry slide rail is connected with the fish outlet 6, and the lower end of the pool entry slide rail is connected with the fish tank; then, the air charging device 4 is opened, air is charged into the air bag 3, the air bag 3 is inflated, and the water and the band fish fry in the temporary breeding box 2 are lifted together, when the water in the temporary breeding box 2 reaches the position of the fish outlet 6, the water and the band fish fry in the temporary breeding box 2 are unloaded into the fish tank through the fish outlet 6 and the pool entry slide rail. Since the band fish non-damage transfer device adopts the air bag 3 inflation mode to lift the water and the band fish fry, the band fish fry spontaneously flows with the water in the temporary breeding box 2 through the fish outlet 6 and the pool entry slide rail and is unloaded into the fish tank, so that the stress level can be reduced, mechanical damage of the fry in the transfer process can be effectively avoided, and the survival rate of the fry after entering the tank can be improved. On the other hand, during the process of opening the air charging device 4, charging air into the air bag 3, and inflating the air bag 3, the operator can also adjust the inflation rate of the air bag 3 according to the performance of the band fish fry in the box, so as to further control and reduce the stress behavior of the band fish, and improve the survival rate of the fry after entering the tank. It can be seen that, compared with the live fish transfer method in the prior art, the transfer method using the band fish non-damage transfer device of the present application has the advantages of convenient operation, high transfer rate, reduced stress level, effectively avoiding mechanical damage of the fry in the transfer process, and improved survival rate of the fry after entering the tank.

[0056] Specifically, as shown in Figure 2 , Figure 3 the band fish non-damage transfer device comprises a transfer trolley 1, a temporary breeding box 2, an air bag 3, an air charging device 4, and a linkage valve body 9. The temporary breeding box 2 is arranged on the transfer trolley 1. The side wall of the temporary breeding box 2 is provided with a fish outlet 6 at the upper portion. Specifically, the temporary breeding box 2 is provided with an open top. The top of the temporary breeding box 2 is provided with a detachably connected box cover 5. In this way, the band fish fry and water can be conveniently put into the temporary breeding box 2.

[0057] The fish outlet 6 extends outward from the side wall of the temporary breeding box 2 to form a fish outlet pipe 6.1. The fish outlet 6 is provided with an openable sealing cover 7, and specifically, the sealing cover 7 is arranged at the end portion of the fish outlet pipe 6.1. In this way, when the pool entry slide rail is connected, it is beneficial to connect the upper end of the pool entry slide rail with the fish outlet 6.

[0058] The sealing cover 7 is used to seal the fish outlet 6. In this embodiment, one side of the sealing cover 7 is hinged on the left side or the right side of the fish outlet 6.1, and the sealing cover 7 is connected with the fish outlet 6.1 by buckling. Of course, the sealing cover 7 can also be screwed on the fish outlet 6.1, or the sealing cover 7 is directly buckled on the fish outlet 6.1.

[0059] The air bag 3 is located in the temporary breeding tank 2 and is fixed on the inner bottom surface of the temporary breeding tank 2. The air bag 3 is provided with an inflation port. The inflation device 4 is in communication with the inflation port through an inflation pipeline. In this embodiment, the inflation device 4 is arranged on the transfer trolley 1 outside the temporary breeding tank 2. The inflation device 4 is a gas pump or a blower.

[0060] The linkage valve body 9 is connected to the inflation pipeline to control the opening and closing of the inflation pipeline. The linkage valve body 9 is linked with the sealing cover 7. When the sealing cover 7 is closed, the linkage valve body 9 is closed. When the sealing cover 7 is opened, the linkage valve body 9 is opened.

[0061] The specific use of the one kind of band fish non-damage transfer device in this embodiment is as follows,

[0062] The one kind of band fish non-damage transfer device is moved to the designated position by the transfer trolley 1, and the fish outlet 6 is opened; then, the pool entry slide rail is connected, the pool entry slide rail is distributed in an inclined manner, the upper end of the pool entry slide rail is connected with the fish outlet 6, and the lower end of the pool entry slide rail is connected with the fish tank; then, the inflation device 4 is started, the air bag 3 is inflated, and the air bag 3 is expanded, so that the water in the temporary breeding tank 2 and the band fish fry are lifted together, when the water in the temporary breeding tank 2 reaches the position of the fish outlet 6, the water in the temporary breeding tank 2 and the band fish fry are unloaded into the fish tank through the fish outlet 6 and the pool entry slide rail. Since the one kind of band fish non-damage transfer device adopts the expansion of the air bag 3 to lift the water body and the band fish fry, the band fish fry spontaneously flows through the fish outlet 6 and the pool entry slide rail together with the water in the temporary breeding tank 2 and is unloaded into the fish tank, so that the stress level can be reduced, mechanical damage caused by the fish fry in the transfer process can be effectively avoided, and the survival rate of the fish fry after entering the tank can be improved. On the other hand, during the process of starting the inflation device 4, inflating the air bag 3, and expanding the air bag 3, the operator can also adjust the expansion rate of the air bag 3 according to the performance of the band fish fry in the tank, so as to further control and reduce the stress behavior of the band fish and improve the survival rate of the fish fry after entering the tank. It can be seen that, compared with the existing art of live fish transfer into the tank, the transfer method using the one kind of band fish non-damage transfer device has the advantages of convenient operation, high transfer rate, reduced stress level, effectively avoiding mechanical damage caused by the fish fry in the transfer process, and improved survival rate of the fish fry after entering the tank.

[0063] In the process of the device for non-destructive transportation of ribbonfish transporting, the sealing cover 7 on the fish outlet 6 needs to be disassembled and the fish outlet 6 needs to be opened before the air bag 3 is inflated and expanded. However, in the actual operation process, the operator may forget to open the sealing cover 7 and directly open the inflation device 4 to expand the air bag 3, so that the water in the temporary breeding box 2 cannot flow out through the fish outlet 6 when reaching the position of the fish outlet 6, but overflow through the upper port of the temporary breeding box 2, causing serious stress behavior of the ribbonfish larvae, causing self-injury, impact and other behaviors, and even causing the ribbonfish larvae to escape from the temporary breeding box 2. In order to solve this problem, the embodiment sets a linkage valve body 9 on the inflation pipeline, which is linked with the sealing cover 7. When the sealing cover 7 is closed, the linkage valve body 9 is closed; when the sealing cover 7 is opened, the linkage valve body 9 is opened; in this way, without affecting the normal use of the device for non-destructive transportation of ribbonfish, the problem that the operator forgets to open the sealing cover 7 and directly opens the inflation device 4 to expand the air bag 3, so that the water in the temporary breeding box 2 cannot flow out through the fish outlet 6 when reaching the position of the fish outlet 6, but overflow through the upper port of the temporary breeding box 2, causing serious stress behavior of the ribbonfish larvae, causing self-injury, impact and other behaviors, and even causing the ribbonfish larvae to escape from the temporary breeding box 2 can be avoided.

[0064] Specifically, the linkage valve body 9 is fixed on the outer side of the temporary culture box body 2 through a mounting bracket. The linkage valve body 9 comprises a valve cavity, a front interface 9.1 and a rear interface 9.2 which are in communication with the valve cavity, and a linkage rod 9.5. The inflation pipeline 8 comprises a front pipeline 8.1 connecting the inflation device 4 and the front interface 9.1, and a rear pipeline 8.2 connecting the inflation port and the rear interface 9.2. A piston 9.3 is arranged in the valve cavity in a sliding sealing connection. The piston 9.3 is connected with a piston rod 9.4. The piston rod 9.4 penetrates through one end of the valve cavity and extends to the outside of the linkage valve body 9, and the piston rod 9.4 is in sealing connection with the linkage valve body 9 through a sealing ring. The linkage rod 9.5 is parallel to the piston rod 9.4. The linkage rod 9.5 is connected with the piston rod 9.4 through a connecting piece. The linkage rod 9.5 is connected with the piston rod 9.4. The linkage rod 9.5 faces the sealing cover 7. In the process of closing the sealing cover 7, the sealing cover 7 will abut against the linkage rod 9.5 and drive the piston rod 9.4 and the piston 9.3 to move in the direction of the front interface 9.1. When the sealing cover 7 is closed, the linkage rod 9.5 abuts against the sealing cover 7, the piston 9.3 is located between the front and rear interfaces 9.2, and the linkage rod 9.5 limits the movement of the piston 9.3 in the direction of the rear interface 9.2. In this way, after the sealing cover 7 is closed, since the piston 9.3 moves to between the front and rear interfaces 9.2 and the movement of the piston 9.3 in the direction of the rear interface 9.2 is limited by the linkage rod 9.5, the linkage valve body 9 is closed, at this time, even if the inflation device 4 is turned on, the gas cannot enter the air bag 3 through the inflation pipeline, so as to avoid the expansion of the air bag 3. When the sealing cover 7 is opened, since the movement of the piston 9.3 is not limited by the linkage rod 9.5, after the inflation device 4 is turned on, the gas enters the valve cavity through the front pipeline and the front interface 9.1, then drives the piston 9.3 to move in the direction of the rear interface 9.2, and makes the front interface 9.1 communicate with the rear interface 9.2, so as to make the gas enter the air bag 3 through the rear pipeline, so as to make the air bag 3 expand, which does not affect the normal use of the live bandfish non-damaging transportation device.

[0065] In the embodiment, the linkage valve body 9 is located above the fish outlet 6, so that when the pool entry slide rail is connected, the pool entry slide rail can be prevented from interfering with the linkage valve body 9, which is beneficial to the connection of the upper end of the pool entry slide rail with the fish outlet 6. Of course, it should be noted that the linkage valve body 9 can also be located below or on the left and right sides of the fish outlet 6.

[0066] In the embodiment, the air bag 3 is further provided with an exhaust valve which is located outside the temporary culture box body 2 and releases the gas in the air bag 3 through the exhaust valve.

[0067] Further, as shown in FIG. 1, the live bandfish non-damaging transportation device further comprises a pool entry slide rail 5 which is connected with the fish outlet 6 and is used to guide the live bandfish to enter the pool. Figure 3As shown, a limiting block 9.6 is arranged on the inner wall of the valve cavity, the limiting block is located between the front interface 9.1 and the rear interface 9.2, and the piston 9.3 and the rear interface 9.2 are located on the same side of the limiting block. In this way, the piston 9.3 can be prevented from moving to the side of the front interface 9.1 of the valve cavity and passing through the front interface 9.1, so that the front interface 9.1 is located between the piston 9.3 and the rear interface 9.2, and the normal work of the linkage valve body 9 is affected.

[0068] Further, as shown in the drawings, Figure 2 As shown, the fish outlet 6.1 and the side wall of the temporary breeding box 2 are connected through a circular arc transition. In this way, during the process of transporting the seaperd larvae into the pool, when the seaperd larvae pass through the fish outlet 6.1, the mechanical damage to the body surface of the seaperd larvae can be further reduced.

[0072] A transportation method into the pool using a seaperd non-damage transportation device, in turn, includes the following steps,

[0073] First, move a seaperd non-damage transportation device to a designated position by a transportation trolley 1; then, open the sealing cover 7.

[0074] Second, connect the pool entry slide rail. The pool entry slide rail is distributed in an inclined manner, the upper end of the pool entry slide rail is connected with the fish outlet 6, and the lower end of the pool entry slide rail is connected with the breeding pool. The inner wall surface of the pool entry slide rail is covered with velvet.

[0075] Third, open the inflator 4, inflate the air bag 3, make the air bag 3 expand, so as to lift the water and the juvenile fish in the temporary breeding tank 2 together, when the water in the temporary breeding tank 2 reaches the fish outlet 6, the water and the juvenile fish in the temporary breeding tank 2 are unloaded into the fish tank through the fish outlet 6 and the pool slide. Specifically, in the process of expanding the air bag 3 to lift the water and the juvenile fish in the temporary breeding tank 2 together, the operator can also observe the performance of the juvenile fish in the temporary breeding tank 2 to adjust the expansion rate of the air bag 3, so as to further control and reduce the stress behavior of the juvenile fish and improve the survival rate of the juvenile fish after entering the pool. Since the fish transporting device of the present application uses the air bag 3 to lift the water and the juvenile fish, the juvenile fish can spontaneously flow with the water in the temporary breeding tank 2 through the fish outlet 6 and the pool slide, thereby reducing the stress level, effectively avoiding mechanical damage to the juvenile fish during transportation, and improving the survival rate of the juvenile fish after entering the pool. On the other hand, in the process of opening the inflator 4, inflating the air bag 3, and expanding the air bag 3, the operator can also adjust the expansion rate of the air bag 3 according to the performance of the juvenile fish in the tank, thereby further controlling and reducing the stress behavior of the juvenile fish and improving the survival rate of the juvenile fish after entering the pool. Therefore, compared with the existing fish transporting method, the fish transporting device of the present application has the advantages of convenient operation, high transporting speed, low stress level, effectively avoiding mechanical damage to the juvenile fish during transportation, and improving the survival rate of the juvenile fish after entering the pool.

[0076] The above is only a preferred embodiment of the present application, not any limitation on the present application, any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application are still within the protection scope of the technical solution of the present application.
