Description

Technical Field

[0001] The invention relates to the technical field of fish fry breeding, in particular to a fish fry temporary breeding system which is convenient for putting in. Background Art

[0002] When the fry are released into the natural environment for breeding, they need to be placed in a breeding box for temporary breeding. When the fry grow to a specified size, they can be released into the natural environment for breeding, which will greatly increase the survival rate of the fry. Therefore, a fry temporary breeding system is needed to temporarily breed the fry.

[0003] Authorization announcement number CN114190322B discloses a temporary fish fry rearing system, relating to the field of fish fry breeding, including a temporary holding pond and a net cage for being placed in the temporary holding pond, wherein both ends of the bottom surface of the net cage in the length direction are fixedly connected to mounting rods, both ends of the mounting rods in the length direction are plugged with connecting rods, and the ends of the connecting rods away from the mounting rods are fixedly connected to rollers, the temporary holding pond is provided with a track for sliding the rollers, and the net cage is provided with a driving assembly for driving the connecting rods to slide, and the connecting rods slide to disengage from the track. This application has the effect of facilitating the placement of the net cage in the temporary holding pond, but when the net cage is placed into the temporary holding pond, the net cage falls directly from the top of the temporary holding pond to the water surface, and the vibration when the net cage falls can easily cause the death of the fry. When the net cage enters the temporary holding pond, it needs to be placed on the top of the temporary holding pond by a lifting device.

For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0048] See also Figure 1 and Figure 2 The present invention provides an embodiment: a temporary fish fry rearing system that is convenient for release, comprising: a breeding box 100, at least three breeding pools are provided at equal distances on the top of the breeding box 100, each breeding pool is equipped with an oxygen pipe 200, a release mechanism 300 is installed on the top of the breeding box 100, a net cage 400 is provided on the release mechanism 300, the release mechanism 300 can place the net cage 400 into the breeding pool by hoisting, and the release mechanism 300 includes a moving component, a release component, a limiting component, and a bearing component;

[0049] It should be noted that when the cage 400 is placed on the placing component, the bearing component is used to support its bottom during placement. After the cage 400 is placed, the placing component works and rises onto the moving component. At this time, the moving component works to drive the cage 400 to move in the breeding tank 100. When the cage 400 moves to the top of the designated breeding pond, the placing component can work to place the cage 400 into the breeding pond. When the cage 400 is inside the breeding pond, the oxygen pipe 200 can work to supply oxygen to the fry.

[0050] As Figure 1-Figure 3 shown, the moving component includes a moving trolley 310, a pulley block 311 and a slide rail 314. The moving trolley 310 is arranged on the top of the breeding tank 100. The moving trolley 310 is in a "U" shape with an opening facing left. Two groups of pulley blocks 311 are symmetrically installed at the bottom right side of the moving trolley 310. The pulley block 311 can move horizontally along the upper surface of the slide rail 314, and the slide rail 314 is fixedly installed on the top of the breeding tank 100;

[0051] It can be imagined that when the pulley block 311 works, it can travel horizontally on the slide rail 314. When the pulley block 311 travels horizontally, it can drive the moving trolley 310 to move. When the moving trolley 310 moves, it can move the cage 400 to a designated position.

[0052] As Figure 1 and Figure 3 shown, the placing component includes a placing frame 320, a lifting ring 321, a winding disc 323 and a lifting rope 324. The placing frame 320 is movable inside the moving trolley 310. At least four lifting rings 321 are symmetrically and fixedly installed on the front and rear sides of the placing frame 320 through assembly grooves. A lifting rope 324 is connected to each of the four lifting rings 321. The other end of the lifting rope 324 is connected to the winding disc 323. Rotating the winding disc 323 can wind and unwind the lifting rope 324. The winding and unwinding of the lifting rope 324 can lift and lower the placing frame 320 through the lifting ring 321;

[0053] It is worth noting that when in use, the net cage 400 can be placed on the delivery rack 320. After the net cage 400 is placed, the reel 323 can be rotated to reel in the hanging rope 324. When the hanging rope 324 is reeled in, the delivery rack 320 and the net cage 400 can be lifted through the lifting ring 321. When the delivery rack 320 and the net cage 400 are lifted to the inside of the mobile trolley 310, the parts can be moved from the opening of the mobile trolley 310 to the inside of the mobile trolley 310. When the net cage 400 is moved to the designated position, the mobile trolley 310 drives the net cage 400 to move to the top of the designated breeding pond. At this time, the reel 323 can be rotated to release the hanging rope 324. When the hanging rope 324 is released, the net cage 400 on the delivery rack 320 can be placed to the designated position in the breeding pond through the lifting ring 321.

[0054] like Figure 1-Figure 3 As shown, the moving assembly also includes a connecting plate 312 and an auxiliary wheel 313. The two ends of the rotating rollers of the two pulley sets 311 are rotatably mounted with connecting plates 312. The side of the connecting plate 312 close to the slide rail 314 rotates the auxiliary wheel 313. The rotating pulley set 311 can drive the auxiliary wheel 313 to slide horizontally at the top of the groove on the side of the slide rail 314 through the connecting plate 312.

[0055] It can be understood that when the pulley group 311 travels on the slide rail 314, it can drive the connecting plates 312 at both ends to move. When the connecting plates 312 move, they can drive the auxiliary wheels 313 to move. When the auxiliary wheels 313 move, they can slide horizontally at the top of the side groove of the slide rail 314, thereby forming a state in which the pulley group 311 and the auxiliary wheels 313 clamp the slide rail 314, and then the delivery rack 320 can make the mobile trolley 310 more stable when lifting the net cage 400.

[0056] like Figure 3 The cam 326 is connected to the cam 327 by a screw thread, and the cam 327 is connected to the cam 327 by a screw thread.

[0057] When the cam 325 is in the unlocked position, the guide frame 327 is locked and the upper and lower ends of the guide frame 327 are locked.

[0058] like Figures 1-4 As shown, the delivery assembly also includes a docking rod 328, a docking groove 329 and a placement platform 3210. The delivery rack 320 is fixedly installed with a docking rod 328 on one side of the opening of the mobile trolley 310. The end of the docking rod 328 is provided with a T-shaped slider that matches the docking groove 329. The docking groove 329 is opened on one side of the breeding tank 100. When the delivery rack 320 is lowered, it can drive the T-shaped slider at the end of the docking rod 328 to move vertically in the docking groove 329. The placement platforms 3210 are symmetrically installed on the four inner walls of the breeding tank 100. The upper surface of the placement platform 3210 is provided with an arc plate for limiting the position of the cage. The distance between the two corresponding arc plates is the same as the length and width of the cage 400.

[0059] It should be noted that the mobile trolley 310 can drive the delivery rack 320 to move to the designated position on the top of the breeding pond. At this time, the delivery rack 320 will drive the T-shaped slider on the docking rod 328 to move to the top of the docking groove 329. When the delivery rack 320 descends, it can drive the T-shaped slider at the end of the docking rod 328 to slide in the docking groove 329. When the T-shaped slider slides in the docking groove 329, the delivery rack 320 and the cage 400 can be stabilized. When the T-shaped slider slides to the bottom of the docking groove 329, the cage 400 can be placed on the placement table 3210. The placement table 3210 is provided with an arc plate to guide the cage 400, so that the cage 400 can be accurately placed at the designated position on the placement table 3210, and the distance between the arc plates is the same as the length and width of the cage 400, so that the arc plates can limit the left and right and front and back of the cage 400.

[0060] like Figure 1 、 Figure 4 and Figure 6The cam 346 is fixedly mounted on the bottom of the fixing plate 344, and the second sliding plate 346 is slidably connected to the bottom of the fixing plate 344. The cam 346 is fixedly mounted on the bottom of the fixing plate 344, and the second sliding plate 346 is slidably connected to the bottom of the fixing plate 344. The cam 346 is fixedly mounted on the bottom of the fixing plate 344, and the second sliding plate 346 is slidably connected to the bottom of the fixing plate 341. The cam 346 is fixedly mounted on the bottom of the fixing plate 344, and the second sliding plate 346 is slidably connected to the bottom of the fixing plate 341. The cam 346 is driven by the second sliding plate 346 to move horizontally on the bottom of the fixing plate 341.

[0061] It is conceivable that the bottom of the net box 400 is placed on the upper surface of the bearing block 340. Since the weight of the net box 400 itself presses the bearing block 340 downward, the bearing block 340 can move vertically in the installation groove 341 when being squeezed. When the bearing block 340 moves, it can drive the fixing plate 344 at the bottom to squeeze the elastic member. At the same time, the fixing plate 344 can drive the first slide plate 345 to move vertically in the installation groove 341 through the elastic member on the side.

[0062] When the supporting block 340 is squeezed, it can move horizontally into the installation groove 341. When the supporting block 340 moves horizontally, it can drive the fixing plate 344 to squeeze the elastic parts on the side. When the fixing plate 344 squeezes the elastic parts on the side, it can drive the second slide plate 346 to move horizontally in the installation groove 341 through the elastic parts at the bottom.

[0063] like Figure 1 、 Figure 4 and Figure 6 As shown, the bearing assembly also includes an extrusion groove 342, an extrusion rod 343 and a slot 347. The side of the bearing block 340 is penetrated by an extrusion groove 342, and one side of the extrusion groove 342 is provided with an inclined surface. The interior of the delivery rack 320 is movably connected to the extrusion rod 343 through the assembly groove. One end of the extrusion rod 343 is installed with a driving part that can push the extrusion rod 343 to move horizontally in the assembly groove of the delivery rack 320. When the extrusion rod 343 moves horizontally, the inclined surface of the extrusion groove 342 can be squeezed by the push rod on the side, so that the bearing block 340 moves horizontally in the installation groove 341. Both sides of the cage 400 close to the bearing block 340 are provided with slots 347 that match the bearing block 340.

[0064] It is worth noting that when the driving unit is working, it can push the squeezing rod 343 to slide in the assembly groove of the delivery rack 320. When the squeezing rod 343 slides, it can drive the side push rod to slide in the squeezing groove 342. When the push rod slides, it can squeeze the inclined surface of the squeezing groove 342. When the inclined surface of the squeezing groove 342 is squeezed, it can drive the bearing block 340 to move horizontally into the installation groove 341. When the bearing block 340 moves into the installation groove 341, it will separate from the bottom of the net box 400. At this time, the net box 400 will fall onto the placement table 3210.

[0065] When the cage 400 falls onto the placement table 3210, it will drive the slot 347 opened on the side to move to the corresponding position of the supporting block 340. When the cage 400 needs to be taken out of the breeding pond, the delivery rack 320 will move to the opening position of the mobile trolley 310. The delivery rack 320 moves downward and can be sleeved on the outer surface of the cage 400. At the same time, the delivery rack 320 will drive the supporting block 340 located inside the installation groove 341 to move to the side of the slot 347. At this time, the push rod will move out of the extrusion groove 342, and the supporting block 340 can be inserted into the interior of the slot 347 through the elastic force of the elastic part, and the cage 400 can be taken out of the breeding pond by the rising of the delivery rack 320.

[0066] like Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the limiting assembly includes a guide block 330, a strip guide groove 331 and an annular guide groove 332. The surfaces of the two winding discs 323 close to the inner side of the mobile trolley 310 are fixedly mounted with guide blocks 330. The surfaces of the guide blocks 330 are provided with positioning holes. The inner side of the operating groove 322 is provided with a strip guide groove 331. Both ends of the strip guide groove 331 are provided with annular guide grooves 332. The guide blocks 330 can move horizontally in the strip guide groove 331 and slide in an annular guide groove 332.

[0067] It can be understood that when the guide block 330 is located inside the strip guide groove 331, the screw rod 326 rotates clockwise to drive the internal threaded sleeve 325 and the winding disk 323 to move horizontally in the operating groove 322, and the winding disk 323 drives the guide block 330 to slide horizontally in the strip guide groove 331. When the guide block 330 slides to the inside of the annular guide groove 332 near the opening of the moving trolley 310, the internal threaded sleeve 325 is in an unrestricted state. At this time, the screw rod 326 continues to rotate clockwise to drive the internal threaded sleeve 325 and the winding disk 323 to rotate. When the winding disk 323 rotates, the delivery rack 320 can be lowered to the designated position to receive the net box 400.

[0068] After the net box 400 is received, the screw rod 326 rotates counterclockwise to drive the winding disc 323 to lift the delivery rack 320. When the delivery rack 320 is lifted to the specified position, the winding disc 323 can be restricted. At the same time, the winding disc 323 drives the guide block 330 to rotate to the end of the strip guide groove 331. Since the winding disc 323 is in a restricted state, the screw rod 326 rotates in the opposite direction to drive the internal threaded sleeve 325 and the winding disc 323 to move horizontally toward the inside of the movable trolley 310. When the winding disc 323 moves horizontally, it drives the guide block 330 to slide into the inside of the annular guide groove 332 at the other end of the strip guide groove 331.

[0069] The guide block 330 is located in the annular guide groove 332, so that the winding disk 323 is in an unrestricted state. At this time, the screw rod 326 rotates clockwise to drive the internal threaded sleeve 325 and the winding disk 323 to rotate to place the cage 400 on the delivery rack 320 into the interior of the breeding pond. After the cage 400 is placed, the screw rod 326 rotates counterclockwise again to lift the delivery rack 320 through the winding disk 323.

[0070] like Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the limiting assembly also includes a movable plate 333, a positioning rod 334 and a first magnet 335. The movable plate 333 is movably installed inside the movable trolley 310 through the assembly slot. The movable plate 333 and the assembly slot of the movable trolley 310 are connected by an elastic member. Both ends of the movable plate 333 are fixedly installed with positioning rods 334 that match the positioning holes of the guide block 330. One end of the positioning rod 334 passes through the assembly slot of the movable trolley 310 and is connected to the inside of the annular guide groove 332 at the end of the operating slot 322. The movable plate 333 moves horizontally in the assembly slot of the movable trolley 310 to drive the positioning rod 334 to be inserted into the positioning hole of the guide block 330 for limiting the position. A first magnet 335 is fixedly installed in the middle of the movable plate 333, and one end of the first magnet 335 passes through the assembly slot of the movable trolley 310.

[0071] It should be noted that after the cage 400 is placed inside the breeding tank, the rotation of the winding disk 323 will drive the delivery rack 320 to move upward. When the delivery rack 320 moves to the designated position, the winding disk 323 will also drive the side guide block 330 to rotate to the position of the end of the strip guide groove 331. When the delivery rack 320 moves to the designated position, it will drive the second magnet 337 to move to a position close to the first magnet 335. At this time, the mutual attraction between the second magnet 337 and the first magnet 335 will make the first magnet 335 close to the second magnet 337, and the first magnet 335 will move to the designated position. When the trolley 310 is moved, the movable plate 333 can be driven to slide in the assembly groove of the movable trolley 310. When the movable plate 333 slides, the elastic part can be squeezed. When the movable plate 333 slides, the positioning rods 334 at both ends will be driven to move. When the positioning rods 334 move, they can be inserted into the positioning holes of the guide blocks 330. When the positioning rods 334 are inserted into the positioning holes of the guide blocks 330, the winding disc 323 can be restricted. After the winding disc 323 is restricted, the screw rod 326 rotates clockwise to drive the winding disc 323 and the delivery rack 320 to move horizontally toward the opening direction of the movable trolley 310.

[0072] like Figure 1 、 Figure 3-Figure 6 As shown, the limiting assembly also includes a movable frame 336 and a second magnet 337. The movable frame 336 is movably installed on the interior of the delivery frame 320 near the first magnet 335 through the assembly slot. The movable frame 336 is connected to the assembly slot of the delivery frame 320 by an elastic member. The two ends of the movable frame 336 pass through the assembly slot of the delivery frame 320 and are connected to the upper part of the installation slot 341. The movable frame 336 has an inclined surface. The second magnet 337 is fixedly installed on the center of the movable frame 336 near the first magnet 335. The second magnet 337 is magnetically connected to the first magnet 335.

[0073] It should be noted that when the net cage 400 is placed inside the delivery rack 320, it presses the supporting block 340 downward. When the supporting block 340 is squeezed to a specified position, it separates from the end of the movable rack 336. At this time, the movable rack 336 and the second magnet 337 can be reset by the elastic member. When the movable rack 336 is reset, the inclined surface of the end thereof is inserted into the interior of the mounting groove 341.

[0074] When the cage 400 falls into the breeding pond, the supporting block 340 can be reset through the elastic part at the bottom. When the supporting block 340 is reset, it can squeeze the inclined surface of the end of the movable frame 336. When the end of the movable frame 336 is squeezed, it can slide in the assembly groove of the delivery frame 320. When the movable frame 336 slides, it can stretch the elastic part and at the same time drive the second magnet 337 to approach the outside of the delivery frame 320.

[0075] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
