Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, and more specifically to an automatic sludge suction machine for aquaculture ponds. Background Technology
[0002] With rapid social development, my country's marine aquaculture industry, including the large yellow croaker industry, is facing new challenges. Changes in the nearshore marine environment, an aging workforce, and market demand for higher-quality seafood are all placing higher demands on traditional large yellow croaker seedling and aquaculture. On the other hand, the continuous innovation of new equipment such as drones and robots, and the transformation and application of automation and intelligence in various industries, especially in the increasing number of successful demonstrations in planting, animal husbandry, and other agricultural fields, are bringing new opportunities for mechanized and digital development to the fisheries industry. The industrialized breeding technology for large yellow croaker is also entering a window of opportunity for iterative upgrades.
[0003] Traditional fisheries are mostly located along coastlines, and large yellow croaker hatcheries are generally situated in remote coastal areas with inconvenient transportation and communication. This makes them less attractive to young people, resulting in a serious aging workforce and difficulties in promoting new equipment and technologies. Furthermore, the production facilities of each hatchery are limited by water and site conditions, built according to the terrain, lacking unified standards, which also hinders the application and promotion of equipment. Currently, there is also a limited market for equipment specifically designed for marine environments, and the significant differences in application scenarios have all contributed to the slow development of mechanization and intelligentization in large yellow croaker breeding.
[0004] Currently, seedling farms have a large number of breeding ponds. After a period of breeding, the sludge at the bottom of the breeding ponds needs to be treated, otherwise it will affect the water quality environment. At present, most seedling farms clean the breeding ponds manually after draining the water. This method is labor-intensive, has a low level of mechanization and intelligence, and is not conducive to the scale and expansion of the industry. Moreover, with the decrease in the number of employees and the aging population, this low-value labor needs to be replaced by automated equipment. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the present invention provides an automatic sludge suction machine for aquaculture ponds, which can automatically collect and clean the sludge at the bottom of the pond without emptying the pond, thus reducing the intensity of manual labor.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic sludge suction machine for aquaculture ponds, comprising: device body; Several wheels are located at the bottom of the device body to provide power for the device to move and to allow the bottom of the device body to be suspended above the bottom of the aquaculture pond. The sludge suction mechanism includes a sludge suction port located at the bottom of the device body, a sludge collection chamber located inside, and a drain outlet located at the top. The sludge suction port faces the bottom of the pool and is used to suck up sediment. The sludge collection chamber is used to collect the sludge. The drain outlet is used to discharge the sucked-up pool water back into the pool. A water pump connects the suction port and the drainage port, providing the power for water flow. The steering mechanism includes sensing components located on four sides of the device body, and control components electrically connected to and controlling the rotation direction of the traveling wheels.
[0007] The present invention is further configured such that: the sludge suction mechanism includes a filter cylinder, the filter cylinder includes a sludge inlet section and a water outlet section, the sludge inlet section is located on one side of the sludge suction port, the water outlet section is located on one side of the drain outlet, and the area between the sludge inlet section and the water outlet section of the filter cylinder forms a sludge collection chamber.
[0008] The present invention is further configured such that: a conical hole with a larger outer diameter and a smaller inner diameter is provided on the peripheral wall of the filter cylinder, and the conical hole forms the inlet section.
[0009] The present invention is further configured such that: one end of the filter cylinder is provided with a filter screen that traps dirt and supplies water, and the other end is open, with the filter screen forming a water outlet section.
[0010] The present invention is further configured such that: a drive motor is provided inside the device body, and the drive motor drives the filter cylinder to rotate.
[0011] The invention is further configured such that: the device body is provided with an installation cavity, the installation cavity is provided with a detachable scraper, the scraper extends into the filter cylinder, and is used to scrape off the dirt remaining inside the inlet section and the outlet section.

[0013] The present invention is further configured such that: the sensing component includes a protruding collision portion with a streamlined outer surface, and a pressure sensor is disposed within the collision portion.
[0014] The invention is further configured such that: four traveling wheels are provided and located at the four corners; the traveling wheels are configured as spherical structures; two traveling wheels diagonally distributed at the four corners have the same direction of rotation; a power wheel is provided above the traveling wheels to abut and cooperate with the surface of the traveling wheels to transmit power; and the control component is electrically connected to the power source of the power wheel.
[0015] The present invention is further configured such that: there are two power wheels, which are located on both sides of the center line of the walking wheel and clamp the walking wheel, and the end face of the power wheel that abuts against the walking wheel has friction texture.
[0016] In summary, the present invention has the following beneficial effects: This invention features an automated sludge suction machine that moves automatically across the bottom of the pond via its wheels. During movement, the suction mechanism automatically removes sludge and deposits it in the collection chamber. A steering mechanism is triggered when the machine hits the side wall of the pond, and after adjusting its direction, the suction machine continues to move. This process repeats, achieving automated cleaning of the entire bottom of the pond and significantly reducing manual labor intensity.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] This embodiment discloses an automatic sludge suction machine for aquaculture ponds, such as... Figure 1-7 As shown, it includes: The device body 1 is used to support and install various components. At the same time, the joints of the device body 1 are all sealed to ensure that water will not enter the interior through the gaps and damage the internal circuits, motors and other electronic components.
[0028] Several wheels 2 are located at the bottom of the device body 1 to provide power for the device to move and to allow the bottom of the device body 1 to be suspended from the bottom of the aquaculture pond. The gap formed after the suspension allows the dirt at the bottom and the water around the perimeter to enter from the side, which is convenient for subsequent sludge suction.
[0029] The suction mechanism 3 includes a suction port 31 located at the bottom of the device body 1, a collection chamber 32 located inside, and a drain port 33 located at the top. The suction port 31 faces the bottom of the pool and is used to suck up the sediment. The suction port 31 has a funnel-shaped structure, which provides a larger suction range. The collection chamber 32 is used to collect the sediment. The drain port 33 is used to discharge the sucked pool water back into the pool. The drain port 33 is equipped with a cover with grid holes on the side, so that the water is discharged from the side when draining. The resistance of the grid structure reduces the impact force when the water is discharged. This can avoid excessive stirring of the water and prevent the sediment at the bottom of the pool from being stirred up by the water. The sediment can be relatively stably settled at the bottom of the pool and sucked up by the suction port 31. A water pump, connecting the suction port 31 and the discharge port 33, provides the power for water flow; The steering mechanism includes sensing components located on the four sides of the device body 1, and a control component electrically connected to and controlling the rotation direction of the traveling wheels 2.
[0030] Furthermore, refer to Figure 2-3 The suction mechanism 3 includes a filter cylinder 35, which comprises a sludge inlet section 351 and a water outlet section 352. The sludge inlet section 351 is located on one side of the suction port 31, and the water outlet section 352 is located on the other side of the drain port 33. The area between the sludge inlet section 351 and the water outlet section 352 of the filter cylinder 35 forms a sludge collection chamber 32. Through the above structure, water carrying sludge enters the filter cylinder 35 from the sludge inlet section 351, and then the water is discharged from the water outlet section 352, while the sludge is retained in the sludge collection chamber 32.
[0031] As a further preferred embodiment, the filter cartridge 35 has conical holes on its peripheral wall, wider on the outside and narrower on the inside, forming an inlet section 351. The conical holes allow water carrying impurities to enter more easily through the larger holes, but because the inner holes are smaller, the trapped impurities are more difficult to discharge, thus preventing impurities from returning to the aquaculture pond from the inlet section 351. As a further preferred embodiment, one end of the filter cartridge 35 is provided with a filter screen that traps dirt and allows water to pass through, while the other end is open, with the filter screen forming a water outlet section 352. The filter screen allows water to pass through but traps most of the dirt, thereby achieving dirt filtration and collection. The open end of the filter cartridge facilitates cleaning of the internal dirt after suction is complete.
[0032] Furthermore, refer to Figure 3 The device body 1 is equipped with a drive motor 5, which drives the filter cylinder 35 to rotate. A gear set 11 is provided on the output shaft of the drive motor 5 and the outer circumferential surface of the filter cylinder 35. The drive motor 5 drives the filter cylinder 35 to rotate through the meshing transmission of the gear set 11. Furthermore, the device body 1 is provided with an installation cavity 9, which contains a detachable scraper 321. The scraper 321 extends into the filter cylinder 35 to scrape off residual dirt inside the inlet section 351 and the outlet section 352. (Refer to...) Figure 1-2 A cover plate 10 is provided on the side of the main body 1 of the device. Opening the cover plate 10 connects to the internal mounting cavity 9. A slot structure is provided above the mounting cavity 9, and a locking block is provided on the scraper 321. The locking block and the slot are detachably connected by sliding engagement. Thus, by rotating the filter cylinder 35, the scraper 321 can scrape off the dirt attached to the mesh of the filter screen and the inner surface of the conical holes, thereby ensuring that the sucked water and dirt can flow smoothly without clogging. At the same time, the drive motor 5 is controlled by the control system. In a simple case, the filter cylinder 35 can be periodically cleaned by rotating it at a timed interval. In a better case, a flow rate sensor can be used to monitor the water volume and flow rate at the suction port and the drain port. When a significant drop occurs, it indicates that there may be a blockage inside. At this time, the drive motor 5 can be controlled to rotate the filter cylinder 35 to prevent clogging.
[0033] Further, as a preferred option, refer to Figure 3-4The scraper 321 is designed with an L-shaped structure and has an inclined structure 6. The L-shaped scraper can scrape away dirt from the inlet section 351 and outlet section 352 as the filter cylinder 35 rotates. The inclined structure 6 collects dirt during the final cleaning, facilitating manual removal of the dirt from the filter cylinder. Specifically, after cleaning the aquaculture pond, the vacuum cleaner is removed. Residual water inside the vacuum mechanism flows out from the bottom suction port. The cover 10 is opened manually, and the filter cylinder 35 is rotated several times using a manually controllable button. This scrapes off the dirt remaining on the inner surface, causing it to fall onto the inclined structure 6. The operator then removes the scraper 321 from the filter cylinder 35, cleans up the fallen dirt, and reinstalls the scraper to complete the cleaning process. Therefore, the scraper of this invention has two functions: firstly, it prevents dirt from clogging the filter screen and other parts for extended periods during the operation of the vacuum cleaner. Secondly, after the sludge is sucked up, the scraper scrapes the sludge onto the inclined structure 6, making it easier for manual cleaning.
[0034] Furthermore, the sensing component includes a protruding, streamlined collision part 8, within which a pressure sensor is installed. This streamlined structure of the collision part 8 reduces water resistance, preventing the internal pressure sensor from being triggered by water resistance when the moving speed increases. When the collision part 8 impacts the wall of the aquaculture pond, the internal pressure sensor is triggered, informing the control component that the edge of the pond has been reached, thus initiating a turning action according to the pre-set program. Specifically, the aquaculture pond is a square pond. The vacuum cleaner starts from one corner, linearly vacuuming along the length of the square structure. After impacting the other side of the pond wall, the turning mechanism moves the vacuum cleaner a short distance in the width direction (equivalent to the width of the vacuum cleaner itself). Then, the vacuum cleaner continues along the length direction back to the other side, forming a reciprocating cleaning path, cleaning the pond bottom section by section until the cleaning is complete.
[0035] Furthermore, refer to Figure 5 The traveling wheels 2 are arranged in four corner positions. Two traveling wheels 2 arranged diagonally at the corners have the same direction of rotation, such as... Figure 5As indicated by the arrows next to the central traveling wheels 2, one set of diagonal traveling wheels drives the device body 1 to move along the length of the aquaculture pond, while another set of diagonal traveling wheels drives the device body 1 to move along the width of the aquaculture pond. The two sets of diagonal traveling wheels are independently controlled to move the vacuum cleaner. The advantage of this diagonal distribution is that it provides good support and ensures that the path remains straight during movement. In this embodiment, choosing different rotation directions of the traveling wheels 2 to drive the device body 1 ensures that the orientation of the device body 1 does not change when the vacuum cleaner moves in various directions. This ensures that the waterproof cable 12 supplying power to the vacuum cleaner always extends and shortens in one direction, preventing rotation and tangling issues.
[0036] Reference Figure 7 The walking wheel 2 is designed as a spherical structure because of the working method of the walking wheel in this application. When the vacuum cleaner needs to move along... Figure 7 When the device body 1 moves in the direction indicated by the arrow, a set of diagonally opposite walking wheels 2a rotates to drive the device body 1; while the other set of walking wheels 2b does not rotate at this time. Therefore, the spherical structure allows the flowing water and dirt to flow away smoothly from both sides of the spherical walking wheels 2b. If it were a traditional cylindrical wheel or track structure, the side of the wheel would obstruct the water and dirt, causing blockage on the side and affecting long-term operation.
[0037] Furthermore, refer to Figure 6 A power wheel 21 is positioned above the traveling wheel 2, abutting against its surface to transmit power. A control component is electrically connected to a power source 22 of the power wheel 21. Preferably, two power wheels 21 are provided, located on either side of the centerline of the traveling wheel 2 and clamping it. The end faces of the power wheels 21 that abut against the traveling wheel 2 have friction textures. With this structure, the power wheels 21 drive the spherical traveling wheel 2 to achieve rotation. Thus, the rotation shaft of the power source 22 and the power wheels 21 can all be housed internally, facilitating sealing. This arrangement also allows for further adjustment of the power wheel's position using components such as servos. By changing the position and rotation direction of the power wheels 21, the spherical traveling wheel 2 can achieve different rotation directions, thus leveraging the omnidirectional rotation capability of the spherical traveling wheel 2 for greater flexibility in practical applications. For example, in… Figure 6A servo motor is installed between the two drive wheels 21, which can control the drive wheels 21 and the power source 22 to rotate 90 degrees. When the servo motor is stationary, the rotation of the drive wheels drives the traveling wheels to rotate in a direction perpendicular to the drawing. When the servo motor rotates 90 degrees, the rotation of the drive wheels drives the traveling wheels to rotate in a direction parallel to the drawing. With all four traveling wheels having this structure, the mobility of the entire vacuum cleaner is greatly improved. This means that it can move not only using a reciprocating covering path, but also a spiral covering path if the aquaculture pond is circular.
[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
