DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 9 As shown, the device for releasing fish fry for proliferation in the present invention comprises a storage unit, a discharge mechanism, a control mechanism, a disinfection mechanism and an oxygen supply mechanism.

[0023] The storage part includes a containing box 1, a partition plate 3 and a material guide plate 2, wherein the partition plate 3 is fixedly mounted on the inner wall of the containing box 1, the containing box 1 is used to be connected to the hull, and the material guide plate 2 is obliquely mounted on the side wall of the partition plate 3, wherein a plurality of partition plates 3 are provided, and the inner cavity of the containing box 1 is divided into a plurality of independent chambers for storing fry by the plurality of partition plates 3 and the material guide plates 2.

[0024] When releasing the fry, a fixed amount of fry is put into an independent chamber, and the fry in the independent chamber is completely discharged each time, so as to control the number of fry released in the target waters. In addition, if different types of fry need to be released in the target waters, before the fry are placed in the chamber separated by the partition plate 3, firstly, according to the number of fry to be released, the different types of fry are placed in the same chamber, and when releasing, the fry in the corresponding chamber is completely released, so as to achieve the accurate release of fry in proportion in the target waters.

[0025] The discharge mechanism includes a discharge port 16 and a closed gate 11 . The discharge port 16 is opened on the outer wall of the containing box 1 and is located at the lowest end of the guide plate 2 . When the fry are released, the fry are discharged to the target water area through the discharge port 16 .

[0026] The closing gate 11 is slidably mounted on the outer wall of the containing box 1 and is used to close the discharge port 16. During the transportation of the fry, the closing gate 11 closes the discharge port 16. When the fry are released, the sliding closing gate 11 exposes the discharge port 16 to facilitate the discharge of the fry.

[0027] In order to facilitate the fish fry to adapt to the water environment of the target water area when they are released, the control mechanism is used to extract water resources from the release water area and discharge them into the inner cavity of the containing box 1. By extracting water from the target water area into the containing box 1, the fish fry can be "transferred through water" to facilitate the fish fry to adapt to the water environment of the target water area and improve the survival rate after release.

[0028] The disinfection mechanism includes a storage box 14 and a control pump 21. The storage box 14 is fixedly mounted on the inner wall of the accommodating box 1 and is located at the bottom of the guide plate 2. The input end of the control pump 21 is connected to the inner cavity of the storage box 14. The storage box 14 is used to store a disinfectant selected from a mixture of potassium permanganate and water.

[0029] The disinfectant in the inner cavity of the storage box 14 is transported to the inner cavity of the containing box 1 by controlling the pump 21, and the disinfectant in the storage box 14 is extracted into the containing box 1 by controlling the pump 21, so as to disinfect the fry, thereby preventing infection of the fry wounds and further improving the survival rate of the released fry.

[0030] In addition, a delivery pipe for delivering disinfectant is provided on the outer wall of the storage box 14 to facilitate delivery of the disinfectant.

[0031] When disinfecting the fry, it is necessary to stop pumping water from the target water area into the interior of the containing box 1. The oxygen supply mechanism includes an oxygen supply pump 13, an air supply pipe 6 and an exhaust pipe 9. The oxygen supply mechanism supplies oxygen to the water in the containing box 1 during disinfection to prevent the fry from dying due to lack of oxygen.

[0032] The oxygen supply pump 13 passes oxygen into the inner cavity of the storage box 14 below the liquid level through the air supply pipe 6, and the oxygen inside the storage box 14 is discharged into the interior of the containing box 1 through the exhaust pipe 9. The oxygen supply pump 13 draws air into the storage box 14, and mixes it with the disinfectant and then discharges it into the containing box 1, thereby disinfecting the air discharged into the containing box 1. At the same time, by discharging air into the liquid inside the storage box 14, the disinfectant can be stirred and mixed, thereby keeping the disinfectant uniform and improving the disinfection effect.

[0033] 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 containing box 1, the water injection pipe 7 is fixedly installed on the upper end surface of the containing box 1, and a nozzle is arranged at the bottom of the water injection pipe 7. The number of the nozzles corresponds to the chambers separated by the partition plate 3, so as to facilitate the injection of water into different chambers.

[0034] 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 inside the three-way pipe 5 , wherein 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 containing box 1 .

[0035] When water is injected into the interior of the containing box 1, 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 containing box 1 through the three-way pipe 5, so as to control the circulation flow of the water inside the containing box 1 through the transfer pump 4.

[0036] As a preferred embodiment of the present invention, a transfer tube 19 is fixedly mounted on the upper end surface of the material guide plate 2 , and a cavity is provided inside the transfer tube 19 .

[0037] The inner cavity of the adapter tube 19 is connected to the output end of the control pump 21. A discharge hole 20 is provided on the upper end surface of the adapter tube 19. The control pump 21 extracts the disinfectant inside the storage box 14 and injects it into the inner cavity of the adapter tube 19, and then discharges it into the interior of the storage box 1 through the discharge hole 20.

[0038] The upper end surface of the adapter cylinder 19 is rotatably mounted with a mounting shaft 15, and the radial outer wall of the mounting shaft 15 is fixedly mounted with a guide vane 18. When the disinfectant is discharged from the discharge hole 20, the water flow impacts the guide vane 18 to control the rotation of the mounting shaft 15, thereby achieving stirring of the disinfectant inside the containing box 1, so that the fry can be evenly contacted with the disinfectant.

[0039] A flexible strip 17 is fixedly installed on the axial end of the mounting shaft 15. When the mounting shaft 15 rotates, the flexible strip 17 rotates synchronously. The rotation of the flexible strip 17 drives the fry to swim. When the fry are frightened and swim, the flow of water inside the containing box 1 is disturbed, further improving the mixing efficiency of the disinfectant inside the containing box 1, so that the fry can fully contact with the disinfectant.

[0040] One end of the gas delivery pipe 6 extends to the inner cavity of the storage box 14 and is fixedly installed with a shunt pipe 23 , wherein the shunt pipe 23 is located below the liquid level in the inner cavity of the storage box 14 in real time.

[0041] The outer wall of the shunt pipe 23 is provided with exhaust holes 36, 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 supply pipe 6, the air is discharged through the exhaust holes 36 to achieve mixing of external air and disinfectant, while disturbing the water body inside the storage box 14 to facilitate the stirring of the disinfectant.

[0042] A sliding plug 35 is elastically installed on the inner wall of the shunt tube 23, and the outer wall of the sliding plug 35 is in sealing fit with the inside of the shunt tube 23. A spring connected to the shunt tube 23 is arranged on the outer wall of the sliding plug 35. After the sliding plug 35 is slidably adjusted, the sliding plug 35 is reset by controlling the elastic force of the spring.

[0043] When gas is injected into the shunt pipe 23, as the gas pressure inside the shunt pipe 23 increases, the sliding plug 35 slides, and a mounting rod 38 is fixedly installed on one axial end of the sliding plug 35, and a sealing ring 37 for sealing the exhaust holes 36 is fixedly installed on the outer wall of the mounting rod 38, wherein the number of the sealing rings 37 is consistent with the number of the exhaust holes 36. When the sliding plug 35 slides, the sealing rings 37 are driven to move synchronously by the mounting rod 38, so that multiple exhaust holes 36 are exhausted synchronously, thereby achieving uniform exhaust at different positions inside the storage box 14.

[0044] 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 in the inner cavity of the containing box 1, and an electronic valve is provided at any position of the inner wall of the exhaust pipe 9 to prevent the liquid inside the containing box 1 from flowing back to the inner cavity of the storage box 14.

[0045] A load-bearing plate 12 is fixedly mounted on the outer wall of the accommodating box 1, and a control cylinder 10 is fixedly mounted on the upper end surface of the load-bearing plate 12. The control cylinder 10 is a common electric telescopic rod. The movable end of the control cylinder 10 passes through the load-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 by the control cylinder 10 to control the closing and conduction of the discharge port 16.

[0046] A support frame 24 is fixedly mounted on the inner wall of the storage box 14 , and a transmission shaft 27 is rotatably mounted on the inner wall of the support frame 24 . The support frame 24 provides a mounting and supporting position for the transmission shaft 27 .

[0047] A spoiler 28 is fixedly installed on the radial outer wall of the transmission shaft 27. There are multiple spoilers 28, which are evenly arranged in a ring shape along the axis of the transmission shaft 27. Rotating the transmission shaft 27 disturbs the water inside the storage box 14 through the spoilers 28 to facilitate the full dissolution of the solid medicine in the storage box 14.

[0048] A mounting tube 25 is fixedly mounted on the upper end surface of the support frame 24. One axial end of the transmission shaft 27 extends to the inner cavity of the mounting tube 25 and is connected to the mounting tube 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 mounting tube 25. After the transmission shaft 27 is rotated, the elastic force of the torsion spring is used to control the transmission shaft 27 to reset.

[0049] A traction rope 26 is fixedly connected to the radial outer wall of the transmission shaft 27, and one end of the traction rope 26 extends to the outer wall of the mounting tube 25. The traction rope 26 is wound around the outer wall of the transmission shaft 27. The traction rope 26 is pulled back and forth in cooperation with the elastic force of the torsion spring to control the reciprocating rotation of the transmission shaft 27, thereby controlling the rotation of the spoiler 28 to achieve stirring and dissolution of the solid disinfectant in the storage box 14.

[0050] A guide cylinder 8 is fixedly installed on the upper end surface 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 closing plug 22 is elastically installed in the inner cavity of the guide cylinder 8. The inner and outer walls of the closing plug 22 are sealed with the inner wall of the guide cylinder 8, and the upper end of the closing plug 22 is connected to the inner wall of the guide cylinder 8 by a spring. When the air pressure inside the storage box 14 increases, the closing plug 22 slides upward. When the air pressure inside the storage box 14 decreases, the closing plug 22 is pushed to return to its original position by the spring.

[0051] When the oxygen supply pump 13 injects air into the storage box 14, the electronic valve on the inner wall of the exhaust pipe 9 is closed. 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. The sealing plug 22 is reset by the elastic force, and the reciprocating switch of the electronic valve is used to control the reciprocating sliding of the sealing plug 22.

[0052] One end of the traction rope 26 away from the transmission shaft 27 is fixedly connected to the bottom surface of the closing plug 22. When the closing plug 22 slides back and forth, the traction rope 26 cooperates with the torsion spring to control the rotation of the transmission shaft 27 to achieve stirring and mixing of the disinfectant.

[0053] A driving wheel 31 is fixedly installed at the axial end of the transmission shaft 27, and a driven wheel 33 meshing with the driving wheel 31 is rotatably installed on the inner wall of the mounting cylinder 25. When the transmission shaft 27 rotates, the driven wheel 31 drives the driven wheel 33 to rotate. 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.

[0054] A guide ring 29 is sleeved on the outer wall of the transmission shaft 27 . A threading hole 32 is opened on the outer wall of the guide ring 29 for the traction rope 26 to pass through. The position of the transmission shaft 27 winding the traction rope 26 can be adjusted by sliding the guide ring 29 .

[0055] A guide plate 30 is fixedly installed on the outer wall of the guide ring 29, and a reciprocating screw 34 passes through the guide plate 30 and is connected by 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, thereby making the traction rope 26 evenly wound around the outer wall of the transmission shaft 27 to maintain the stability of operation.
