Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a shrimp and crab feeding device for photovoltaic pond aquaculture. Background Technology

[0002] Photovoltaic pond aquaculture is a highly efficient utilization model that combines photovoltaic power generation and aquaculture, achieving a synergistic effect of power generation and aquaculture within the same space. However, the installation of photovoltaic panels typically requires support from pillars, which are densely distributed across the pond surface. These pillars serve both to fix the photovoltaic panels and to provide the necessary load-bearing structure for the photovoltaic system. In this aquaculture model, the presence of the photovoltaic panels and pillars can obstruct the feeding devices for shrimp and crabs during actual operation, resulting in uneven distribution of feed across the pond surface and affecting the normal feeding of shrimp and crabs.

[0003] Existing feeding devices typically employ mechanical rotary spraying or fixed-point dispensing methods, lacking design specific to the structural characteristics of photovoltaic ponds. These devices cannot effectively avoid the pillars during feeding, causing feed to be blocked and concentrated in certain areas, affecting feed utilization efficiency and potentially causing localized water pollution. Furthermore, in complex water conditions with unevenly distributed pillars, traditional devices have limited feeding range, are prone to collisions with pillars, and their position is easily obstructed by pillars when traveling to distant areas, making effective control difficult and failing to meet the needs of modern photovoltaic pond aquaculture.

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 10 The image shows a shrimp and crab feeding device for photovoltaic pond aquaculture, comprising: a base frame 1; a drive module 2, which is centrally fixed below the base frame 1; a feeding module 3, which is fixedly fixed above the base frame 1 relative to the drive module 2; a guide module 4, of which two sets are symmetrically arranged on the front and rear sides of the base frame 1; the guide module 4 is equipped with a clamping unit 41 capable of clamping a support column 72; a correction module 5, of which two sets are symmetrically arranged on the left and right sides of the base frame 1; the correction ends of the two sets of correction modules 5 are respectively radially oriented towards the left and right sides of the base frame 1; and a monitoring module 6, of which two sets are vertically fixed on the two sets of correction modules 5, and the detection ends of the two sets of monitoring modules 6 are respectively radially oriented towards the left and right sides of the base frame 1.

[0039] The photovoltaic module 7 consists of multiple sets of photovoltaic panels 71 arranged in a rectangular array and support columns 72 for supporting the multiple sets of photovoltaic panels 71.

[0040] When the feeding module 3 needs to be driven to feed material in a straight line between multiple sets of support columns 72 arranged in a rectangular array, the feeding module 3 is first placed on the water surface to be fed. Then, the drive module 2 is activated, driving the base frame to move along the preset feeding path in coordination with the feeding module 3, thereby gradually completing the feeding process. To ensure that the feeding device always moves along the correct path during the feeding process, the monitoring module 6 tracks the direction of travel of the feeding module 3 in real time while the base frame 1 moves forward. If the direction of travel of the feeding module 3 deviates, the monitoring module 6 can immediately provide feedback to the correction module 5, which will initiate a correction action to correct the path of the feeding module 3, ensuring that the feeding module 3 always moves smoothly along the predetermined feeding path until the feeding task is completed.

[0041] When the feeding module 3 needs to feed in an S-shape along multiple sets of support columns 72, it is first placed on the water surface to be fed, and the drive module 2 is activated to move the feeding module 3 toward the support columns 72. When the feeding module 3 approaches the support column 72, the drive module 2 simultaneously activates two sets of guide modules 4, namely the first guide module and the second guide module. The clamping unit 41 in the first guide module first clamps and fixes the support column 72. At this time, the feeding module 3 is advanced forward by the drive module 2 and rotates to feed around the support column 72 fixed by the clamping unit 41. As the feeding module 3 continues to rotate, the clamping unit 41 in the second guide module will contact the adjacent support column 72 and begin to clamp the support column 72. At this time, the clamping unit 41 in the first guide module releases, and the feeding module 3 continues to rotate to feed around the support column 72 clamped by the second guide module. By repeating this process, the feeding module 3 successfully completes the feeding along an S-shaped path between the support columns 72 until the feed for the entire area is fed.

[0042] The feeding module 3 can flexibly avoid and adapt to the arrangement of multiple sets of support columns 72, ensuring the accuracy and stability of the feeding path. Especially when feeding in an S-shaped bend, the feeding module 3 can smoothly turn between multiple support columns 72, ensuring uniform feeding in each area and avoiding obstruction by the support columns 72 during the feeding process. In addition, the real-time monitoring and automatic correction functions effectively improve feeding efficiency and accuracy, reduce the need for manual intervention, optimize the automation level of the feeding operation, and thus improve feed utilization.

[0043] See Figure 8 As shown: The drive module 2 includes a connecting frame 21, a floating ring 22, a fixed base 23, a servo motor 24, and a drive propeller 25; the floating ring 22 is centrally fixedly disposed below the base frame 1 via the connecting frame 21; the servo motor 24 is centrally fixedly disposed below the base frame 1 via the fixed base 23 and located inside the floating ring 22; the drive propeller 25 is fixedly disposed at the drive end of the servo motor 24, and the drive propeller 25 is used to drive the base frame 1 to move.

[0044] The main function of the floating ring 22 is to provide sufficient buoyancy for the base frame 1 to ensure its stability on the water surface. When it is necessary to drive the base frame 1 to move in a predetermined direction, the external power supply is first connected to the system to start the servo motor 24. The servo motor 24, through a synchronous drive mechanism, links the movement of the drive propeller 25 to ensure that the drive propeller 25 can automatically adjust to a suitable driving attitude according to the actual transmission requirements. In this way, the drive propeller 25 can precisely adjust its angle during operation to ensure that the base frame 1 moves stably and smoothly along the preset feeding trajectory on the water surface. In addition, the adjustment action of the drive propeller 25 can be flexibly adjusted according to the movement path requirements of the base frame 1, thereby providing precise guidance and ensuring that the feeding module 3 completes the feeding task according to the set path.

[0045] The floating ring 22 provides continuous buoyancy support to the base frame 1, ensuring its balance on the water surface and preventing tilting or instability due to insufficient buoyancy. The coordinated operation of the servo motor 24 and the drive propeller 25 allows the feeding module 3 to flexibly adjust its direction of movement and precisely control the forward trajectory of the base frame 1. This solves the problems of driving accuracy and stability of the feeding module 3 on the water surface, ensuring smooth feeding operations.

[0046] See Figure 10 As shown: The guide module 4 further includes a linear drive unit 42 capable of driving the clamping unit 41 radially closer to or further away from the base frame 1; the linear drive unit 42 is horizontally fixed on the base frame 1 via an adjustment seat and is located close to the edge of the base frame 1; the clamping unit 41 is horizontally fixed on the drive end of the linear drive unit 42 and is arranged perpendicular to the drive end of the linear drive unit 42.

[0047] When the clamping module needs to be driven radially closer to or further away from the support column 72 to enable the feeding module 3 to perform S-shaped feeding around the support column, an external power supply is first connected to drive the linear drive unit 42 to start working. The output shaft of the linear drive unit 42 begins to extend, simultaneously driving the clamping unit 41 to move, causing the clamping end of the clamping unit 41 to open and gradually approach the support column 72, accurately aligning with the support column 72 during the extension process. When the clamping unit 41 approaches the support column 72 to a suitable position, the clamping unit 41 is driven further to retract its clamping end, thereby firmly fixing the support column 72 within the clamping unit 41, ensuring that the support column 72 remains in a stable position during the feeding process. Subsequently, the clamping module, through alternating actions, cooperates with the first guide module and the second guide module to effectively achieve the gradual clamping and release of the support column 72. Combined with the S-shaped feeding action, this ensures that the feeding module 3 can accurately bypass the support column 72 and successfully complete the feeding task.

[0048] By precisely controlling the coordinated operation of the linear drive unit 42 and the clamping unit 41, the clamping module can accurately control the clamping action and posture during operation, thereby achieving stable clamping and release of the support column 72. Through this control method, the feeding module 3 can smoothly bypass the support column 72 on an S-shaped path, avoiding problems such as feeding difficulties or deviation from the path caused by obstruction from the support column 72. This design improves the flexibility and accuracy of the feeding module 3, effectively ensuring the stability and continuity of the feeding process, reducing mechanical jamming and operational errors, and optimizing the overall efficiency and feeding quality of the feeding system.

[0049] See Figure 9 As shown: The linear drive unit 42 includes a fixed sleeve rod 421, a telescopic rod 422, an extension plate 423, and an electric push rod 424; the fixed sleeve rod 421 is horizontally fixed on the base frame 1 and is located near the edge of the base frame 1; the telescopic rod 422 is slidably disposed within the fixed sleeve rod 421; the electric push rod 424 is parallel to and fixedly disposed on the fixed sleeve rod 421 along the long side direction, and the driving end of the electric push rod 424 is fixedly connected to the extension plate 423 which is vertically disposed at the front end of the telescopic rod 422.

[0050] The clamping unit 41 is horizontally fixed at the front end of the telescopic rod 422.

[0051] When it is necessary to move the clamping unit 41 horizontally closer to or further away from the base frame 1, an external power supply is first connected to start the electric push rod 424. The output shaft of the electric push rod 424 begins to extend, and the extension of its output shaft synchronously drives the movement of the telescopic rod 422. Guided by the fixed sleeve rod 421, the telescopic rod 422 extends radially along a predetermined path. As the telescopic rod 422 extends, the clamping unit 41, which is fixedly installed at the front end of the telescopic rod 422, also moves radially synchronously, achieving precise control of the clamping unit 41. This process, through the linkage between the electric push rod 424 and the telescopic rod 422, allows the clamping unit 41 to flexibly move closer to or further away from the base frame 1 in the horizontal plane, thereby accurately performing clamping and releasing actions and ensuring smooth operation and precision of the mechanical system.

[0052] See Figure 7 and Figure 9As shown: The clamping unit 41 includes a guide seat 411, a bidirectional lead screw 412, a servo motor 413, a first clamping arm 414, and a second clamping arm 415; the guide seat 411 is horizontally fixedly mounted vertically at the front end of the linear drive unit 42; the bidirectional lead screw 412 is rotatably mounted inside the guide seat 411; the servo motor 413 is fixedly mounted at one end of the guide seat 411 and its output shaft is connected to the bidirectional lead screw 412; the first clamping arm 414 and the second clamping arm 415 are symmetrically slidably mounted inside the guide seat 411, and the connecting ends of the first clamping arm 414 and the second clamping arm 415 are respectively connected to the bidirectional lead screw 412 and are respectively located near the two ends of the guide seat 411.

[0053] The second clamping arm 415 and the first clamping arm 414 have the same structure.

[0054] In the non-clamping state, the first clamping arm 414 and the second clamping arm 415, driven by the bidirectional lead screw 412, are located at opposite ends of the guide seat 411, and are in an open position ready for clamping operation. At this time, due to the action of the bidirectional lead screw 412, the first clamping arm 414 and the second clamping arm 415, guided by their respective threaded ends, can move away from each other along a predetermined track, ensuring the stability and precise positioning of the clamping unit 41. During feeding operations, when the clamping unit 41 moves to both sides of the support column 72 via the linear drive unit 42, ready to clamp, an external power supply is first connected to drive the servo motor 413. The servo motor 413 drives the bidirectional lead screw 412 to rotate via its output shaft. The rotation of the bidirectional lead screw 412 synchronously drives the two threaded ends to move the first clamping arm 414 and the second clamping arm 415 closer together or further apart. At this time, the first and second clamping arms 415 precisely control their relative positions according to the rotation of the bidirectional lead screw 412, ultimately clamping the support column 72. Through this process, the clamping unit 41 can accurately and stably clamp the support column 72 when needed, ensuring the reliability and stability of the feeding module 3 in complex operating environments.

[0055] See Figure 9As shown: The first clamping arm 414 consists of a connecting part 4141, a limiting part 4142, and a rotating part 4143 embedded in the limiting part 4142, which are fixedly connected in sequence; the connecting part 4141 is slidably disposed in the guide seat 411, and a threaded hole for the bidirectional lead screw 412 to pass through is provided on the surface of the connecting part 4141; the limiting part 4142 is fixedly disposed at the front end of the connecting part 4141, and the limiting part 4142 is V-shaped with its included angle being a right angle; multiple sets of rotating parts 4143 are provided, and multiple sets of rotating parts 4143 are equidistantly embedded in the inner side of the limiting part 4142 along the long side direction of the limiting part 4142.

[0056] When the first clamping arm 414 and the second clamping arm 415 approach each other under the drive of the bidirectional lead screw 412 and the servo motor 413, and complete the clamping operation on the support column 72, the clamping unit 41 not only achieves precise clamping of the support column 72, but also ensures the stability of the support column 72 under the limiting action of multiple sets of rotating parts 4143. The design of this limiting part 4142 ensures that the support column 72 still has axial freedom after being clamped, thereby allowing the support column 72 to rotate circumferentially around its axis. To ensure the accuracy and adaptability of the limiting action, the limiting part 4142 is designed with a V-shaped structure. This structure can not only effectively adapt to support columns 72 of different diameters, but also ensure the accuracy of the limiting action when the support column 72 rotates through the tight fit between the contact surface and the support column 72, avoiding problems such as insecure or unstable clamping caused by differences in the size of the support column 72. The V-shaped limiting design effectively improves the versatility and adaptability of the device, enabling the feeding module 3 to work stably on various support columns 72 of different specifications, ensuring stability and safety during operation.

[0057] See Figure 9 As shown: The rotating part 4143 is a rotating roller.

[0058] By incorporating the rotating part 4143, when the first clamping arm 414 and the second clamping arm 415 clamp the support column 72 respectively, the coordinated action of the rotating roller and the clamping arms allows the support column 72 to have axial rotation freedom while being clamped. Specifically, in this process, the rotating roller allows the support column 72 to rotate around its axis while being fixed by the clamping unit 41. This design not only ensures effective clamping of the support column 72 but also avoids the limitation of the support column 72 being unable to rotate due to excessive clamping. When the drive frame 1 moves forward, the frame 1 can rotate freely along the axis of the support column 72, thereby ensuring the smooth rotation of the frame 1 and flexible feeding operation.

[0059] See Figures 1 to 10 As shown: The feeding module 3 is a pneumatic feeder.

[0060] The feeding module 3 is a pneumatic feeder, which uses pneumatic principles to drive the feed delivery. This pneumatic feeder uses airflow pressure to send feed from the storage bin into the water through pneumatic components such as cylinders and valves, and achieves precise feeding by controlling the size and direction of the airflow. The feeding module 3 is existing technology and will not be described in detail here. Other feeders can also be used to achieve uniform feed distribution.

[0061] See Figure 6 As shown: The correction module 5 includes a mounting frame 51, a self-priming pump 52, and a nozzle 53; the self-priming pump 52 is fixedly mounted horizontally on the base frame 1 via the mounting frame 51 and is located near the edge of the base frame 1; the nozzle 53 is vertically mounted on the mounting frame 51 and is located near the bottom of the mounting frame 51; the nozzle 53 and the self-priming pump 52 are connected by a transmission pipeline.

[0062] When the base frame 1 moves forward under the drive of the drive module 2, if it deviates to the left or right, the correction module will immediately initiate the corresponding correction operation upon receiving the deviation correction signal. Specifically, if the base frame 1 deviates to the right, the correction module on the left will initiate the corresponding correction action. First, it will drive the self-priming pump 52 to extract water, which will be transported to the nozzle 53 through the pipeline system. The water jet from the nozzle 53 will apply a counter-thrust force to the base frame 1, generating a torque opposite to the direction of the base frame 1's deviation, thereby effectively correcting the deviation of the base frame 1 and ensuring that the base frame 1 moves accurately along the predetermined trajectory. Conversely, when the base frame 1 deviates to the left, the correction module on the right will perform the same correction process, applying a corresponding counter-thrust force by adjusting the spray direction and water flow rate of the nozzle 53 to ensure that the base frame 1 returns to the correct travel path.

[0063] See Figure 4 As shown, the monitoring module 6 includes a first ranging sensor 61 and a second ranging sensor 62; the first ranging sensor 61 and the second ranging sensor 62 are respectively vertically and centrally disposed on the left and right sides of the base frame 1, and the first ranging sensor 61 and the second ranging sensor 62 are respectively disposed close to the left and right edges of the base frame 1.

[0064] When the feeding device performs a linear feeding operation between the two rows of support columns 72, the distance between the base frame 1 and the support columns 72 can be monitored in real time by the first distance sensor 61 and the second distance sensor 62 respectively installed on the left and right sides of the base frame 1. These distance sensors intermittently detect the distance between the support columns 72 and the base frame 1 on both sides and provide real-time feedback data to determine whether the base frame 1 has deviated from the predetermined forward path. When the forward path of the base frame 1 deviates, the system can quickly identify it and issue an alarm or trigger corrective measures in a timely manner to ensure that the feeding device can travel along the correct path and avoid feeding errors or obstacles caused by deviation.

[0065] This invention not only enables precise avoidance of columns but also allows for alternating feeding around the columns.

[0066] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
