Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a shrimp and crab feeding device for photovoltaic pond farming. Background Art

[0002] Photovoltaic pond aquaculture is a highly efficient model that combines photovoltaic power generation with aquaculture, achieving synergistic effects of power generation and aquaculture within the same space. However, the installation of photovoltaic panels typically requires support from columns. These columns are densely distributed across the pond surface, serving both to secure the panels and provide the necessary load-bearing structure for the system. In this aquaculture model, the presence of the panels and columns can hinder the operation of shrimp and crab feeding systems. This can result in uneven distribution of feed across the pond surface, impacting the normal feeding of shrimp and crabs.

[0003] Existing feeding devices typically utilize mechanical rotary spraying or fixed-point delivery, lacking designs tailored to the structural characteristics of photovoltaic ponds. These devices are unable to effectively avoid pillars during feeding, resulting in feed being blocked and concentrated in certain areas. This not only affects feed utilization efficiency but can also cause localized water pollution. Furthermore, in complex waters with unevenly distributed pillars, traditional devices have a limited feeding range and are prone to collisions with pillars. Furthermore, when the feeding device reaches distant areas, it is easily blocked by pillars, making it difficult to effectively control the feeding device and unable to meet the needs of modern photovoltaic pond aquaculture.

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

[0038] See also Figures 1 to 10 As shown: A shrimp and crab feeding device for photovoltaic pond farming, comprising: a base frame 1; a driving module 2, the driving module 2 is centrally fixedly arranged below the base frame 1; a feeding module 3, the feeding module 3 is fixedly arranged above the base frame 1 relative to the driving module 2; a guiding module 4, the guiding module 4 is provided with two groups, and the two groups of guiding modules 4 are symmetrically arranged on the front and back sides of the base frame 1; the guiding module 4 is provided with a clamping unit 41 capable of clamping the support column 72; a correction module 5, the correction module 5 is provided with two groups, and the two groups of correction modules 5 are symmetrically arranged on the left and right sides of the base frame 1; the correction ends of the two groups of correction modules 5 are respectively arranged radially toward the left and right sides of the base frame 1; a monitoring module 6, the monitoring module 6 is provided with two groups, and the two groups of monitoring modules 6 are respectively vertically fixed on the two groups of correction modules 5, and the detection ends of the two groups of monitoring modules 6 are respectively arranged radially toward the left and right sides of the base frame 1.

[0039] The photovoltaic module 7 is composed of a plurality of photovoltaic panels 71 arranged in a rectangular array and support columns 72 for supporting the plurality of photovoltaic panels 71 .

[0040] When it is necessary to drive the feeding module 3 to feed in a straight line between the multiple groups of support columns 72 arranged in a rectangular array, the feeding module 3 is first placed on the water surface to be fed, and then the driving module 2 is started to drive the frame to cooperate with the feeding module 3 to move along the preset feeding path, 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 forward direction of the feeding module 3 deviates, the monitoring module 6 can immediately feedback to the correction module 5, start the correction action, and correct the path of the feeding module 3 to ensure that the feeding module 3 always moves smoothly along the predetermined feeding path until the feeding task is completed.

[0041] To allow the feeding module 3 to perform an S-shaped, meandering feeding along multiple groups of support columns 72, the feeding module 3 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 columns 72, the drive module 2 simultaneously activates the two groups of guide modules 4: the first guide module 4 and the second guide module 4. The clamping unit 41 in the first guide module 4 first clamps and secures the support columns 72. At this point, the feeding module 3 is propelled forward by the drive module 2 and performs a rotational feeding operation, with the support columns 72 secured by the clamping unit 41 as the center. As the feeding module 3 continues to rotate, the clamping unit 41 in the second guide module 4 contacts and begins to clamp the adjacent support column 72. At this point, the clamping unit 41 in the first guide module 4 releases, and the feeding module 3 continues to rotate and feed, with the support column 72 clamped by the second guide module 4 as the center. By repeating the operation in this way, the feeding module 3 successfully completes the feeding along the S-shaped path between the support columns 72 until the feeding of the feed in the entire area is completed.

[0042] The feeding module 3 flexibly avoids and adapts to the arrangement of multiple support columns 72, ensuring a precise and stable feeding path. Especially during S-shaped feeding, the feeding module 3 smoothly pivots between the multiple support columns 72, ensuring uniform feeding in each area and preventing obstruction by the support columns 72 during feeding. Furthermore, the real-time monitoring and automatic correction features effectively improve feeding efficiency and accuracy, reduce the need for manual intervention, optimize the automation level of feeding operations, and thus increase feed utilization.

[0043] See also Figure 8 As shown: the driving module 2 includes a connecting frame 21, a floating ring 22, a fixing seat 23, a steering gear 24 and a driving paddle 25; the floating ring 22 is fixedly arranged in the center below the base frame 1 through the connecting frame 21; the steering gear 24 is fixedly arranged in the center below the base frame 1 and is located in the floating ring 22 through the fixing seat 23; the driving paddle 25 is fixedly arranged at the driving end of the steering gear 24, and the driving paddle 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 1 to ensure the stability of the base 1 on the water surface. When it is necessary to drive the base 1 to move in a predetermined direction, first connect the external power supply to the system to drive the servo 24 to start working. The servo 24 uses a synchronous drive mechanism to link the action of the drive paddle 25 to ensure that the drive paddle 25 can automatically adjust to the appropriate driving posture according to the actual transmission requirements. In this way, the drive paddle 25 can accurately adjust the angle during operation to ensure that the base 1 moves stably and smoothly along the preset feeding trajectory on the water surface. In addition, the adjustment action of the drive paddle 25 can be flexibly adjusted according to the movement path requirements of the base 1, thereby providing precise guidance to ensure that the feeding module 3 completes the feeding task according to the set path.

[0045] The floating ring 22 provides continuous buoyancy support for the base frame 1, ensuring its balance on the water surface and preventing tilting or instability caused by insufficient buoyancy. The coordinated operation of the servo 24 and the drive paddle 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 driving accuracy and stability issues of the feeding module 3 on the water surface, ensuring smooth feeding operations.

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

[0047] When the clamping module needs to be driven radially toward or away from the support column 72 to enable the feeding module 3 to perform an S-shaped feeding operation, the external power supply is first connected and the linear drive unit 42 is activated. The output shaft of the linear drive unit 42 begins to extend, simultaneously driving the clamping unit 41. The clamping end of the clamping unit 41 opens and gradually approaches the support column 72, precisely aligning with the support column 72 during the extension process. When the clamping unit 41 reaches the desired position near the support column 72, the clamping unit 41 is further driven, causing its clamping end to retract, firmly securing the support column 72 within the clamping unit 41 and ensuring that the support column 72 remains securely positioned throughout the feeding process. Subsequently, the clamping module, through alternating motions, cooperates with the first and second guide modules 4, 4 to effectively and gradually clamp and release the support column 72, facilitating the S-shaped feeding operation and ensuring that the feeding module 3 can precisely bypass the support column 72 and successfully complete the feeding operation.

[0048] By precisely controlling the coordinated operation of the linear drive unit 42 and the clamping unit 41, the clamping module accurately controls its gripping motion and posture during operation, thereby achieving stable grip and release of the support column 72. This control method allows the feeding module 3 to smoothly circumvent the support column 72 along an S-shaped path, avoiding problems such as feeding interruptions or deviations from the feeding path caused by obstruction by the support column 72. This design enhances the flexibility and accuracy of the feeding module 3, effectively ensuring stability and continuity during the feeding process, reducing mechanical jamming and operational errors, and optimizing the efficiency and feeding quality of the entire feeding system.

[0049] See also 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 fixedly arranged on the base frame 1 in a horizontal state and is arranged close to the edge of the base frame 1; the telescopic rod 422 is slidably arranged in the fixed sleeve rod 421; the electric push rod 424 is fixedly arranged on the fixed sleeve rod 421 in parallel along the long side direction of the fixed sleeve rod 421, and the driving end of the electric push rod 424 is fixedly connected to the extension plate 423 vertically arranged 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 drive the clamping unit 41 horizontally toward or away from the base frame 1, first connect the external power supply and drive the electric push rod 424 to start, 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. Under the guidance of 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 fixed at the front end of the telescopic rod 422 also moves radially synchronously to achieve precise control of the clamping unit 41. This process is achieved through the linkage cooperation of the electric push rod 424 and the telescopic rod 422, so that the clamping unit 41 can flexibly approach or move away from the base frame 1 in the horizontal plane, thereby accurately performing the clamping and releasing actions, ensuring the smooth operation and precision of the mechanical system.

[0052] See also Figure 7 and Figure 9As shown: the clamping unit 41 includes a guide seat 411, a bidirectional screw rod 412, a servo motor 413, a first clamping arm 414 and a second clamping arm 415; the guide seat 411 is fixedly arranged in a horizontal state at the front end of the linear drive unit 42; the bidirectional screw rod 412 is rotatably arranged in the guide seat 411; the servo motor 413 is fixedly arranged at one end of the guide seat 411 and its output shaft is transmission connected to the bidirectional screw rod 412; the first clamping arm 414 and the second clamping arm 415 are symmetrically slidingly arranged in the guide seat 411, and the connecting ends of the first clamping arm 414 and the second clamping arm 415 are respectively transmission connected to the bidirectional screw rod 412 and are respectively arranged close to 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 and second clamping arms 414, 415 are positioned at opposite ends of the guide base 411, driven by the bidirectional screw 412. The first and second clamping arms 414, 415 are in an open position, ready for clamping. At this point, guided by their respective threaded ends, the bidirectional screw 412 allows the first and second clamping arms 414, 415 to move away from each other along a predetermined path, ensuring the stability and precise positioning of the clamping unit 41. During feeding operations, when the clamping unit 41 is moved to either side of the support column 72 via the linear drive unit 42, ready for clamping, an external power source is first connected to activate the servo motor 413, which then rotates the bidirectional screw 412 via its output shaft. The rotation of the bidirectional screw 412 synchronously drives the two threaded ends, respectively, to move the first and second clamping arms 414, 415 toward or away from each other. At this time, the first and second clamping arms 415 precisely control their relative positions according to the rotation of the bidirectional screw rod 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 also Figure 9As shown: the first clamping arm 414 is composed 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 set in the guide seat 411, and a threaded hole for the bidirectional screw rod 412 to pass through is opened on the surface of the connecting part 4141; the limiting part 4142 is fixedly set at the front end of the limiting part 4142, and the connecting part 4141 is V-shaped and its included angle is right angled; the rotating part 4143 is provided with multiple groups, and the multiple groups of rotating parts 4143 are embedded and installed on the inner side of the limiting part 4142 at equal distances 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 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, under the limiting action of the multiple sets of rotating parts 4143, can ensure the stability of the support column 72. 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 part, the limiting part 4142 is designed as a V-shaped structure. This structure not only effectively adapts to support columns 72 of different diameters, but also ensures the accuracy of the limiting action when the support column 72 rotates through the close fit of the contact surface with the support column 72, avoiding the problem of loose or unstable clamping due to the size difference of the support column 72. The V-shaped limit design effectively improves the versatility and adaptability of the device, allowing the feeding module 3 to work stably on support columns 72 of various specifications, ensuring stability and safety during operation.

[0057] See also Figure 9 As shown: the rotating portion 4143 is a rotating roller.

[0058] By providing the rotating portion 4143, it is possible to achieve that when the first clamping arm 414 and the second clamping arm 415 respectively clamp the support column 72, the coordinated action of the rotating roller and the clamping arm enables the support column 72 to have the freedom of axial rotation while being clamped. Specifically, in this process, the provision of the rotating roller enables the support column 72 to rotate around its axis while being fixed by the clamping unit 41. This design not only ensures the effective clamping of the support column 72, but also avoids the restriction that the support column 72 cannot rotate due to excessive clamping. When the base frame 1 is driven forward, the base frame 1 can rotate freely based on the axis of the support column 72, thereby ensuring the smooth rotation of the base frame 1 and flexible feeding operation.

[0059] See also Figures 1 to 10 As shown: the feeding module 3 is a pneumatic feeding machine.

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

[0061] See also 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 arranged on the base frame 1 in a horizontal state through the mounting frame 51 and is arranged close to the edge of the base frame 1; the nozzle 53 is arranged vertically on the mounting frame 51 and is arranged close to the bottom of the mounting frame 51; the nozzle 53 and the self-priming pump 52 are connected through a transmission pipeline.

[0062] When the base frame 1 moves forward under the drive of the driving module 2, if there is a left or right deviation, the correction module will immediately start the corresponding correction operation after receiving the deviation correction signal. Specifically, if the base frame 1 deviates to the right, the correction module on the left will start the corresponding correction action, first driving the self-priming pump 52 to extract water, and the extracted water is transported to the nozzle 53 through the pipeline system. The water flow sprayed from the nozzle 53 will apply a reverse thrust to the base frame 1, generating a torque opposite to the deviation direction of the base frame 1, thereby effectively correcting the deviation state 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 the corresponding reverse thrust by adjusting the spray direction and water flow of the nozzle 53 to ensure that the base frame 1 returns to the correct driving path.

[0063] See also Figure 4 As shown: It is characterized in that 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 arranged in a vertical state 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 arranged close to the left and right edges of the base frame 1.

[0064] When the feeding device performs a linear feeding operation between two rows of support columns 72, the first and second distance measuring sensors 61, 62, located on the left and right sides of the base frame 1, monitor the distance between the base frame 1 and the support columns 72 in real time. These distance measuring sensors intermittently detect the distance between the support columns 72 and the base frame 1, providing real-time feedback to determine whether the base frame 1 has deviated from its intended path. If the base frame 1's path deviates, the system quickly identifies this and issues an alarm or triggers corrective measures, ensuring the feeding device remains on track and preventing feeding errors or interruptions caused by deviations.

[0065] The present invention can not only accurately avoid the upright posts but also utilize the upright posts for surrounding alternating feeding.
