Description

Technical Field

[0001] The present invention relates to the technical field of shrimp and crab farming, and particularly relates to a shrimp and crab growth monitoring device. Background Art

[0002] Shrimps and crabs are important aquaculture objects. The success of shrimp and crab farming depends to a large extent on whether suitable farming conditions are provided. This requires reasonable control of the shrimp and crab farming environment to maintain suitable farming conditions. For the control of the shrimp and crab farming environment, it is necessary to rely on a shrimp and crab growth monitoring device for real-time monitoring.

[0003] Shrimp and crab growth monitoring devices are important tools in modern aquaculture to improve production efficiency and ensure the healthy growth of farmed organisms. These devices can monitor water environment parameters and the growth status of shrimps and crabs in real time, helping farmers adjust management measures in a timely manner.

[0004] The existing shrimp and crab growth monitoring device is a buoy-type monitoring device. A variety of water quality monitoring sensors are installed in this buoy-type monitoring device. These water quality monitoring sensors are only distributed at the center of the bottom of the buoy-type monitoring device. However, shrimps and crabs generally live at the bottom of the pond. Although the water quality monitoring sensors on the water surface can monitor the water quality environment of the pond surface in real time, there are certain differences in water quality between the pond surface and the bottom. It is impossible to ensure whether the water quality at the bottom of the pond meets the survival requirements of shrimps and crabs. Moreover, with the change of seasons, the water depth of the shrimp and crab farming pond needs to be adjusted. After the pond depth continues to deepen, the monitoring accuracy will gradually decline. At the same time, the existing buoy-type monitoring device has floating properties and generally needs to be fixed by ropes. When using ropes for fixation, some embedded columns need to be installed, and a relatively long length of rope is required to reach the embedded columns on the pond bank, so the fixation is rather troublesome and not convenient to use.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0034] Refer to Figure 1 , a shrimp and crab growth monitoring device, including a buoy body 1. The buoy body 1 is in a gyro shape and has a perforation at its center. The buoy body 1 is a cavity body. A monitoring mechanism 4 for monitoring the water quality of the shrimp and crab growth pond is arranged in the central perforation of the buoy body 1. A fixing mechanism 2 for fixing the buoy body 1 in the shrimp and crab growth pond is arranged on the circumference of the buoy body 1.

[0035] Refer to Figure 1 , Figure 2 and Figure 3 , the monitoring mechanism 4 includes an anti-collision basket 45 slidably arranged in the central perforation of the buoy body 1. An adjustment component 41 for adjusting the height of the anti-collision basket 45 is jointly arranged on the upper side of the buoy body 1 and in the central perforation. Water inlet slits are formed on the side wall and the bottom wall of the anti-collision basket 45. A circular mounting plate 43 is arranged on the upper side of the anti-collision basket 45. A plurality of mounting holes are equidistantly arranged in a circle on the mounting plate 43. A rod-shaped water quality monitoring sensor 44 (the types of water quality monitoring sensors 44 used include pH sensors, dissolved oxygen sensors, ammonia nitrogen sensors, temperature sensors, and nitrate and nitrite sensors) is placed in each mounting hole. A clamping component 46 for fixing the water quality monitoring sensor 44 is arranged on the upper side of the mounting hole.

[0036] During specific operation, the anti-collision basket 45 provides external protection for various water quality monitoring sensors 44, preventing the water quality monitoring sensors 44 from directly contacting the bottom of the pond and affecting the monitoring effect.

[0037] Refer to Figure 1 、 Figure 4 and Figure 5 The fixing mechanism 2 includes a plurality of arms 11 circumferentially and equidistantly fixedly connected to the periphery of the buoy body 1. An activity hole is formed at the outer end of the arm 11, and a vertically distributed pillar 21 is inserted into the activity hole. A tooth rail 211 is fixedly connected to a side wall of the pillar 21 close to the central axis of the buoy body 1. A first gear 22 is meshed with the tooth rail 211. A pin shaft 23 is fixedly connected to the center of the first gear 22. Both ends of the pin shaft 23 are rotatably connected to a support plate 24, and the lower end of the support plate 24 is fixedly connected to the arm 11. A linkage assembly 26 for controlling the synchronous rotation of each pin shaft 23 is commonly provided on each arm 11. The lower end of the pillar 21 is provided with a head 25 that is hollow inside and in the shape of a top. A secondary compensation component 251 is commonly provided on the head 25 and the pillar 21. A forked component 252 is arranged inside the head 25.

[0038] During specific operation, the linkage assembly 26 controls the rotation of each pin shaft 23 to drive each first gear 22 to control the lifting of each pillar 21 respectively. Each pillar 21 drives each head 25 to lift uniformly, so that each pillar 21 cooperates to automatically fix the buoy body 1, ensuring the fixing stability of the buoy body 1.

[0039] By using the monitoring mechanism 4 and the fixing mechanism 2 in cooperation, the water quality of the shrimp and crab growth pond can be monitored stably and accurately.

[0040] Refer to Figure 1 and Figure 2 The adjustment assembly 41 includes a vertical frame 413 symmetrically fixedly connected to the upper end of the buoy body 1. A lead screw 412 is rotatably connected inside one vertical frame 413, and a guide rod 415 is fixedly connected inside the other vertical frame 413. The upper end of the lead screw 412 extends to the outside of the corresponding vertical frame 413 and is fixedly connected to the output end of the second motor 411. The second motor 411 is fixedly connected to the upper end of the corresponding vertical frame 413. A moving frame 414 extending upward and passing through the through hole is fixedly connected to the upper side of the anti-collision basket 45 at the positions corresponding to the guide rod 415 and the lead screw 412. One moving frame 414 is slidably connected to the vertical frame 413, and the other moving frame 414 is threadedly connected to the lead screw 412.

[0041] During specific operation, the second motor 411 controls the rotation of the lead screw 412. The lead screw 412 controls the moving frame 414 to drive the anti-collision basket 45 to lift along the guide rod 415, so as to control the monitoring probe of the water quality monitoring sensor 44 to dive to different depths, ensuring that the monitoring range of the water quality monitoring sensor 44 is within the shrimp and crab growth environment.

[0042] Refer to Figure 3 , the clamping assembly 46 includes a plurality of fixed rings 464 fixedly connected to the mounting plate 43. The fixed rings 464 are distributed corresponding to the mounting holes one by one. A movable rod 462 extending radially thereof is symmetrically and slidably penetrated through the wall of the fixed ring 464. One end of the movable rod 462 close to the central axis of the fixed ring 464 is fixedly connected with a clamping piece 461. A compression spring 463 is sleeved on a section of the movable rod 462 between the clamping piece 461 and the inner wall of the fixed ring 464. A limiting plate is fixedly connected to the end of the movable rod 462 far from the central axis of the fixed ring 464.

[0043] During specific operation, when the rod-shaped water quality monitoring sensor 44 is inserted into the mounting hole, the clamping piece 461 is controlled by the compression spring 463 to press against the water quality monitoring sensor 44, so as to realize the rapid installation of the water quality monitoring sensor 44.

[0044] Refer to Figure 2 , a waterproof cover 42 is placed on the upper side of the mounting plate 43. A plurality of protrusions are fixedly connected to the peripheries of the mounting plate 43 and the waterproof cover 42 at equal circumferential intervals one by one. Two corresponding protrusions of the mounting plate 43 and the waterproof cover 42 are fixedly connected to the anti-collision basket 45 by bolts. A wire releasing hole is provided at the center of the upper wall of the waterproof cover 42. The wiring of a plurality of water quality monitoring sensors 44 extends to the outside of the waterproof cover 42 through the wire releasing hole and is electrically connected to an external sensor signal receiving system.

[0045] During specific operation, the waterproof cover 42 is used to protect the water quality monitoring sensor 44 from being immersed in water. The monitoring information of each water quality monitoring sensor 44 is transmitted to the sensor signal receiving system through the wiring. The sensor signal receiving system digitizes and visually displays the monitoring information. The wiring of the water quality monitoring sensor 44 uses a spring-shaped wiring to adapt to the depth adjustment of the water quality monitoring sensor 44.

[0046] Refer to Figure 4 and Figure 7, the linkage assembly 26 includes worm gears 261 fixedly connected to the respective pin shafts 23. A worm 262 is meshed and connected to the position of the worm gear 261 close to the central axis of the buoy body 1. The worm 262 is rotatably connected in a mounting frame 263. The mounting frame 263 is fixedly connected to the support arm 11. The lower end of the worm 262 penetrates through the support arm 11 and is fixedly connected to a second gear 266. The second gears 266 are jointly meshed and connected to an external gear ring 2651. The external gear ring 2651 is integrally and fixedly connected to the outer ring of the rotating ring 265. An internal gear ring 2652 is also integrally and fixedly connected to the inner ring of the rotating ring 265. The rotating ring 265 is rotatably connected to the lower side of each support arm 11 through a keyway structure. A third gear 267 is arranged on the lower side of a group of support arms 11. The third gear 267 is meshed and connected to the internal gear ring 2652. The center of the third gear 267 is fixedly connected to the output end of a first motor 264. The first motor 264 is fixedly connected to the upper side of the corresponding support arm 11.

[0047] During specific operation, the first motor 264 is controlled to drive the third gear 267 to rotate. The third gear 267 drives the rotating ring 265 to rotate. The rotation of the rotating ring 265 controls the synchronous rotation of the second gears 266. The second gears 266 drive the worm 262 to control the rotation of the worm gear 261. The worm gear 261 drives the pin shaft 23 to rotate, so as to synchronously rotate the pin shafts 23.

[0048] Refer to Figure 4 and Figure 8 , the secondary compensation component 251 includes a movable column 2513 slidably penetrating through the center of each support column 21. The upper end of the movable column 2513 is fixedly connected to the output end of an electric push rod 2511. The electric push rod 2511 is fixedly connected to the upper end of the support column 21 through a bracket 2512. The abutting head 25 is slidably connected to the lower end of the movable column 2513.

[0049] During specific operation, the electric push rod 2511 is controlled to slide the movable column 2513 in the support column 21. The movable column 2513 drives the abutting head 25 to perform fine height adjustment, so as to adapt to the height fluctuation of the pool bottom.

[0050] Refer to Figure 1 、 Figure 4 and Figure 5, the forked component 252 includes a number of fork branches 2525 that are circumferentially and equidistantly slid through the conical wall of the abutting head 25. A connecting rod 2524 is fixedly connected to the inner end of the fork branch 2525. The lower end of the movable column 2513 extends into the abutting head 25 and is fixedly connected to a frustum block 2522. A number of limiting inclined guide grooves 2523 are formed on the side wall of the frustum block 2522, and the limiting inclined guide grooves 2523 are distributed in one-to-one correspondence with the connecting rod 2524. A ball head is arranged at one end of the connecting rod 2524 close to the frustum block 2522, and the ball head is slidably and limit-connected in the limiting inclined guide groove 2523. A tension spring 2521 is sleeved on the movable column 2513 between the frustum block 2522 and the upper wall of the abutting head 25. The upper end of the tension spring 2521 is fixedly connected to the upper wall of the abutting head 25, and the lower end of the tension spring 2521 is fixedly connected to the frustum block 2522.

[0051] During specific operation, when the movable column 2513 drives the abutting head 25 to contact the bottom of the pool, the abutting head 25 stops moving under the force, and the movable column 2513 continues to move downward to drive the tension spring 2521 to stretch. While the movable column 2513 moves downward, it controls the connecting rod 2524 through the limiting inclined guide groove 2523 of the frustum block 2522 to drive the fork branches 2525 to extend outwards from the abutting head 25 until the lower end of the frustum block 2522 abuts against the inner wall of the abutting head 25. The abutting head 25 will follow the movable column 2513 to move downward and insert into the bottom of the pool. The fork branches 2525 and the abutting head 25 cooperate to support the column 21 in a multi-point manner, improving the installation perpendicularity and stability of the column 21. When the movable column 2513 moves upward, the tension spring 2521 retracts, and the movable column 2513 will pull the frustum block 2522 upward. Through the limiting inclined guide groove 2523 of the frustum block 2522, the connecting rod 2524 is controlled to drive the fork branches 2525 to retract towards the inside of the abutting head 25, so that the column 21 loses the support of the fork branches 2525, facilitating the removal of the abutting head 25. After the tension spring 2521 returns to its initial state, the movable column 2513 drives the abutting head 25 to be pulled out from the bottom of the pool through the tension spring 2521. The tension spring 2521 can make the connection between the abutting head 25 and the movable column 2513 elastic, and can buffer the force on the column 21 when the buoy body 1 is subjected to force fluctuations.

[0052] Refer to Figure 4 , limiting T-grooves 212 are formed on the two side walls of the column 21 that are symmetrically distributed. T-shaped blocks are fixedly connected to the inner wall of the movable hole corresponding to the two limiting T-grooves 212 of the column 21, and the T-shaped blocks are connected in cooperation with the limiting T-grooves 212.

[0053] During specific operation, the limiting T-groove 212 and the T-shaped block cooperate to guide the lifting of the column 21.

[0054] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 6, an energy storage mechanism 3 for supplying energy to the monitoring mechanism 4 and the fixing mechanism 2 is further provided on the upper side of the buoy body 1. The energy storage mechanism 3 includes a ring frame 32 fixedly connected to the upper side of the buoy body 1. The ring frame 32 and the buoy body 1 are coaxial. A plurality of photovoltaic panels 33 are fixedly connected to the periphery of the ring frame 32 at equal intervals in the circumferential direction; the plurality of photovoltaic panels 33 are electrically connected to the energy storage power supply 31, and the energy storage power supply 31 is also electrically connected to a controller (the controller is not shown in the figure). The controller is also electrically connected to a first motor 264, a second motor 411, and an electric push rod 2511. The energy storage power supply 31 is fixedly connected inside the ring frame 32.

[0055] During specific operation, the photovoltaic panels 33 convert light energy into electrical energy and store it in the energy storage power supply 31, and the energy storage power supply 31 supplies energy for the operation of the first motor 264, the second motor 411, and the electric push rod 2511 through the controller.

[0056] When in use:

[0057] S1: The whole monitoring device is placed into the breeding pond of shrimps and crabs. The buoy body 1 has a large buoyancy, and the whole monitoring device floats on the water surface. The monitoring device is moved to a suitable monitoring point by an external force. The photovoltaic panels 33 convert light energy into electrical energy and store it in the energy storage power supply 31, and the energy storage power supply 31 supplies energy for the operation of the first motor 264, the second motor 411, and the electric push rod 2511 through the controller.

[0058] S2: The first motor 264 is used to control the rotation of the third gear 267. The third gear 267 drives the rotation of the rotating ring 265. The rotation of the rotating ring 265 controls the synchronous rotation of each second gear 266. The second gear 266 drives the worm 262 to control the rotation of the worm gear 261. The worm gear 261 drives the rotation of the pin shaft 23, so that the pin shafts 23 rotate synchronously. The rotation of each pin shaft 23 drives each first gear 22 to control the descent of each support column 21 respectively. Each support column 21 drives each abutting head 25 to move downward uniformly towards the bottom of the pond. When any one of the abutting heads 25 touches the bottom of the pond, the unified downward movement of the abutting heads 25 is stopped. Then, the electric push rod 2511 corresponding to the abutting head 25 that does not touch the bottom of the pond is used to control the sliding of the movable column 2513 connected to the abutting head 25 in the support column 21, and the movable column drives the abutting head 25 to perform height fine-tuning respectively, so as to adapt to the height undulation change of the bottom of the pond. When the movable column 2513 drives the abutting head 25 to touch the bottom of the pond, the abutting head 25 stops moving under the force, and the movable column 2513 continues to move downward to drive the tension spring 2521 to stretch. At the same time, when the movable column 2513 moves downward, the limiting inclined guide groove 2523 of the frustum block 2522 controls the connecting rod 2524 to drive the fork 2525 to extend outwards from the abutting head 25 until the lower end of the frustum block 2522 abuts against the inner wall of the abutting head 25.
