Technical Field

[0001] The present invention belongs to the technical field of artificial fish stocking, specifically an artificial fish stocking device for fry stocking. Background Art

[0002] Artificial fish stocking is to directly release or transfer the eggs, larvae or adults of fishery organisms into natural waters such as the ocean, tidal flats, rivers, lakes, and reservoirs by artificial methods to restore or increase the population quantity and improve and optimize the community structure of the water area.

[0003] A patent of Chinese Patent Application CN216722697U discloses an aquaculture artificial fish stocking device. The key points of its technical solution are as follows: It includes a box body with an open upper part. A fry stocking pipe is provided at the lower part of one side of the box body. A step is formed along the opening of the box body. A fixed beam is provided on the side of the step away from the fry stocking pipe. A water return device for lifting the water in the stocking water area into the box body is provided on the fixed beam. A filter water and oxygen increasing device that can be freely taken and placed is provided on the side of the step close to the fry stocking pipe. This technology can transfer a large number of fry at one time. After being transferred to the stocking boat, it can flexibly conduct quantitative fry stocking on a large water area. During the stocking process, through the water return device and the filter water and oxygen increasing device, the water in the stocking water area can be filtered, oxygenated and sent into the box body to improve the adaptability and survival rate of the fry to the stocking water area and improve the effect of artificial fish stocking.

[0004] Although the above technology can transfer a large number of fry at one time and can flexibly conduct quantitative fry stocking on a large water area after being transferred to the stocking boat, since the fry are uniformly stored in the box body, when the required stocking quantity is less than the storage quantity in the box body each time, as the fry are living bodies, they will swim in the box body, resulting in uneven stocking quantity each time and affecting the stocking quality.

Detailed implementation mode

[0040] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0041] As Figures 1 to 9 shown, the fry releasing and putting device of the present invention includes a storage part, a discharging mechanism, a control mechanism, a disinfection mechanism and an oxygen supply mechanism.

[0042] The storage part includes an accommodation box 1, a partition plate 3 and a material guiding plate 2. The partition plate 3 is fixedly installed on the inner wall of the accommodation box 1. The accommodation box 1 is used to connect with the hull. The material guiding plate 2 is inclinedly installed on the side wall of the partition plate 3. Among them, a plurality of partition plates 3 are provided. The inner cavity of the accommodation box 1 is divided into a plurality of independent chambers for storing fry by the plurality of partition plates 3 and the material guiding plate 2.

[0043] When releasing fry, a certain amount of fry is put into an independent chamber, and the fry in the independent chamber is completely discharged each time of putting, so as to control the number of fry put into the target water area. In addition, when different types of fry need to be put into the target water area, before putting the fry into the chambers separated by the partition plates 3, first, according to the quantity to be put, different types of fry are put into the same chamber, and when putting, the fry in the corresponding chamber is completely put, so as to achieve accurate proportional putting of fry in the target water area.

[0044] The discharging mechanism includes a discharge port 16 and a closing gate plate 11. The discharge port 16 is opened on the outer wall of the accommodation box 1 and is located at the lowest end of the material guiding plate 2. When releasing fry, the fry is discharged through the discharge port 16 into the target water area.

[0045] The closing gate plate 11 is slidably installed on the outer wall of the accommodation box 1 and is used to close the discharge port 16. During the process of transporting fry, the closing gate plate 11 closes the discharge port 16. When putting, the closing gate plate 11 is slid to expose the discharge port 16 so as to facilitate the discharge of fry.

[0046] When releasing fry, in order to facilitate the fry to adapt to the water environment of the target water area, the control mechanism is used to extract the water resources of the release water area and discharge them into the inner cavity of the accommodation box 1. By extracting the water body of the target release water area into the accommodation box 1, the "water passing" of the fry is realized, so as to facilitate the fry to adapt to the water environment of the target water area and improve the survival rate after release.

[0047] The disinfection mechanism includes a storage box 14 and a control pump 21. The storage box 14 is fixedly installed on the inner wall of the accommodation box 1 and is located at the bottom of the guide plate 2. The input end of the control pump 21 is communicated with the inner cavity of the storage box 14. Among them, the storage box 14 is used to store a mixture of potassium permanganate and water as the disinfectant.

[0048] The control pump 21 conveys the disinfectant liquid in the inner cavity of the storage box 14 to the inner cavity of the accommodation box 1. The control pump 21 extracts the disinfectant in the storage box 14 into the accommodation box 1 to realize the disinfection of the fry, thereby preventing the fry from wound infection and further improving the survival rate of fry release.

[0049] In addition, a discharge pipe for discharging the disinfectant is arranged on the outer wall of the storage box 14 to facilitate the discharge of the disinfectant.

[0050] When disinfecting the fry, it is necessary to stop pumping water from the target water area into the interior of the accommodation box 1. The oxygen supply mechanism includes an oxygen supply pump 13, an air delivery pipe 6 and an exhaust pipe 9. The oxygen supply mechanism supplies oxygen to the water body in the accommodation box 1 during disinfection to prevent the fry from dying of hypoxia.

[0051] The oxygen supply pump 13 passes oxygen into the liquid level in the inner cavity of the storage box 14 through the air delivery pipe 6. The oxygen inside the storage box 14 is discharged into the interior of the accommodation box 1 through the exhaust pipe 9. The oxygen supply pump 13 extracts air into the storage box 14, mixes it with the disinfectant and then discharges it into the accommodation box 1, so as to disinfect the air discharged into the accommodation box 1. At the same time, by discharging air into the liquid in the storage box 14, the disinfectant can be stirred and mixed to keep the disinfectant uniform and improve the disinfection effect.

[0052] The control mechanism includes a transfer pump 4, a three-way pipe 5 and a water injection pipe 7. The transfer pump 4 is fixedly installed on the outer wall of the accommodation box 1. The water injection pipe 7 is fixedly installed on the upper end surface of the accommodation box 1, and a nozzle is arranged at the bottom of the water injection pipe 7. The number of nozzles corresponds to the chambers separated by the partition plate 3 to facilitate water injection into different chambers.

[0053] One end of the three-way pipe 5 is connected to the input end of the transfer pump 4, and a solenoid valve is arranged in the three-way pipe 5. The other end of the three-way pipe 5 extends into the water body of the target water area, and the remaining end is located inside the accommodation box 1.

[0054] When filling the inside of the accommodation box 1 with water, the input end of the transfer pump 4 is controlled to extend into the target water area through the three-way pipe 5. During disinfection, the input end of the transfer pump 4 is connected to the inner cavity of the accommodation box 1 through the three-way pipe 5, so as to control the circulating flow of the water body inside the accommodation box 1 through the transfer pump 4.

[0055] As a preferred embodiment of the present invention, a transfer cylinder 19 is fixedly installed on the upper end surface of the material guiding plate 2, and a cavity is arranged inside the transfer cylinder 19.

[0056] The inner cavity of the transfer cylinder 19 is connected to the output end of the control pump 21. A medicine discharging hole 20 is opened on the upper end surface of the transfer cylinder 19. After the control pump 21 extracts the disinfectant inside the storage box 14, it is injected into the inner cavity of the transfer cylinder 19, and then discharged into the inside of the accommodation box 1 through the medicine discharging hole 20.

[0057] An installation shaft 15 is rotatably installed on the upper end surface of the transfer cylinder 19. A guide vane 18 is fixedly installed on the radial outer wall of the installation shaft 15. When the disinfectant is discharged from the medicine discharging hole 20, the water flow impacts the guide vane 18 to control the rotation of the installation shaft 15, so as to realize the stirring of the disinfectant inside the accommodation box 1, so that the fry can be evenly contacted with the disinfectant.

[0058] A flexible strip 17 is fixedly installed at the axial end of the installation shaft 15. When the installation shaft 15 rotates, the flexible strip 17 rotates synchronously. By rotating the flexible strip 17, the fry are driven to swim. When the fry are frightened and swim, the water body inside the accommodation box 1 is disturbed, further improving the mixing efficiency of the disinfectant inside the accommodation box 1, so that the fry can fully contact with the disinfectant.

[0059] One end of the air delivery pipe 6 extends into the inner cavity of the storage box 14, and a shunt pipe 23 is fixedly installed, wherein the shunt pipe 23 is always located below the liquid level inside the storage box 14.

[0060] Exhaust holes 36 are opened on the outer wall of the shunt pipe 23, and a plurality of exhaust holes 36 are evenly arranged along the outer wall of the shunt pipe 23. When the oxygen supply pump 13 inputs air into the shunt pipe 23 through the air delivery pipe 6, the air is discharged through the exhaust holes 36, realizing the mixing of the external air and the disinfectant, and at the same time disturbing the water body inside the storage box 14, so as to facilitate the stirring of the disinfectant.

[0061] A sliding plug 35 is elastically installed on the inner wall of the shunt pipe 23. The outer wall of the sliding plug 35 is in sealing fit with the inside of the shunt pipe 23, and a spring connected to the shunt pipe 23 is arranged on the outer wall of the sliding plug 35. After the sliding plug 35 is slid and adjusted, the elastic force of the spring is used to control the sliding plug 35 to reset.

[0062] When injecting gas into the inside of the shunt tube 23, as the air pressure inside the shunt tube 23 increases, the sliding plug 35 slides. An installation rod 38 is fixedly installed at one axial end of the sliding plug 35, and a sealing ring 37 for blocking the exhaust holes 36 is fixedly installed on the outer wall of the installation rod 38. The number of the sealing rings 37 is the same as the number of the exhaust holes 36. When the sliding plug 35 slides, the sealing ring 37 is driven to move synchronously through the installation rod 38, so as to exhaust air from multiple exhaust holes 36 synchronously, realizing uniform exhaust at different positions inside the storage tank 14.

[0063] As a preferred embodiment of the present invention, the exhaust pipe 9 is a U-shaped pipe. The highest position of the exhaust pipe 9 is not lower than the liquid level inside the accommodating tank 1, and an electronic valve is arranged at any position on the inner wall of the exhaust pipe 9 to prevent the liquid inside the accommodating tank 1 from flowing back into the inner cavity of the storage tank 14.

[0064] A bearing plate 12 is fixedly installed on the outer wall of the accommodating tank 1. A control cylinder 10 is fixedly installed on the upper end surface of the bearing plate 12. The control cylinder 10 is a common electric telescopic rod. The movable end of the control cylinder 10 penetrates through the bearing plate 12 and is fixedly connected to the outer wall of the closing gate plate 11. The closing gate plate 11 is controlled to slide through the control cylinder 10 to control the closing and conduction of the discharge port 16.

[0065] A support frame 24 is fixedly installed on the inner wall of the storage tank 14. A transmission shaft 27 is rotatably installed on the inner wall of the support frame 24. The support frame 24 provides an installation and support position for the transmission shaft 27.

[0066] A spoiler 28 is fixedly installed on the radial outer wall of the transmission shaft 27. There are multiple spoilers 28, and the multiple spoilers 28 are uniformly arranged in a ring along the axis of the transmission shaft 27. Rotating the transmission shaft 27 disturbs the water body inside the storage tank 14 through the spoiler 28, so as to facilitate the full dissolution of the solid medicine in the storage tank 14.

[0067] An installation cylinder 25 is fixedly installed on the upper end surface of the support frame 24. One axial end of the transmission shaft 27 extends into the inner cavity of the installation cylinder 25 and is connected to the installation cylinder 25 through an elastic member. The elastic member is a common torsion spring. One end of the torsion spring is connected to the transmission shaft 27, and the other end is connected to the inner wall of the installation cylinder 25. After rotating the transmission shaft 27, the transmission shaft 27 is controlled to reset through the elastic force of the torsion spring.

[0068] A traction rope 26 is fixedly connected to the radial outer wall of the transmission shaft 27. One end of the traction rope 26 extends to the outer wall of the installation cylinder 25. The traction rope 26 is wound around the outer wall of the transmission shaft 27. Pulling the traction rope 26 reciprocally and cooperating with the elastic force of the torsion spring, the transmission shaft 27 is controlled to rotate reciprocally, thereby controlling the spoiler 28 to rotate and realizing the stirring and dissolution of the solid disinfectant in the storage tank 14.

[0069] A guide cylinder 8 is fixedly installed on the upper end face of the storage box 14. The inner cavity of the guide cylinder 8 is communicated with the inner cavity of the storage box 14. A sealing plug 22 is elastically installed in the inner cavity of the guide cylinder 8. The inner and outer walls of the sealing plug 22 are hermetically attached to the inner wall of the guide cylinder 8, and the upper end of the sealing plug 22 is connected to the inner wall of the guide cylinder 8 through a spring. When the air pressure inside the storage box 14 increases, the sealing plug 22 slides upward. When the air pressure inside the storage box 14 decreases, the spring pushes the sealing plug 22 to reset.

[0070] When the oxygen supply pump 13 injects gas into the storage box 14, the electronic valve on the inner wall of the exhaust pipe 9 closes. At this time, the sealing plug 22 slides upward, and then the electronic valve opens. The air inside the storage box 14 is discharged through the exhaust pipe 9, and the sealing plug 22 is reset by the elastic force. By the reciprocating switch of the electronic valve, the reciprocating sliding of the sealing plug 22 is controlled.

[0071] One end of the traction rope 26 away from the transmission shaft 27 is fixedly connected to the bottom surface of the sealing plug 22. When the sealing plug 22 reciprocates, the rotation of the transmission shaft 27 is controlled through the cooperation of the traction rope 26 and the torsion spring, realizing the stirring and mixing of the disinfectant.

[0072] A driving wheel 31 is fixedly installed at the axial end of the transmission shaft 27. A driven wheel 33 meshing with the driving wheel 31 is rotatably installed on the inner wall of the installation cylinder 25. When the transmission shaft 27 rotates, the driven wheel 33 is driven to rotate by the driving wheel 31. A reciprocating screw 34 is fixedly installed at the bottom of the driven wheel 33, and the rotation of the driven wheel 33 drives the reciprocating screw 34 to rotate.

[0073] A guide ring 29 is sleeved on the outer wall of the transmission shaft 27. A threading hole 32 for the traction rope 26 to pass through is formed on the outer wall of the guide ring 29. By sliding the guide ring 29, the position where the transmission shaft 27 winds the traction rope 26 is adjusted.

[0074] A guide plate 30 is fixedly installed on the outer wall of the guide ring 29. The reciprocating screw 34 penetrates through the guide plate 30 and is connected through a reciprocating thread. During the rotation of the transmission shaft 27, the reciprocating screw 34 rotates synchronously, thereby controlling the synchronous reciprocating sliding of the guide plate 30 and the guide ring 29, and further enabling the traction rope 26 to be evenly wound around the outer wall of the transmission shaft 27, maintaining the stability of the operation.
