Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to an automatic collection, filtration and recycling device for uneaten feed and feces in pond aquaculture. Background Technology

[0002] In aquaculture, the accumulation of uneaten feed and feces is one of the key issues restricting aquaculture efficiency. During the aquaculture process, uneaten feed and feces excreted by farmed organisms continue to accumulate at the bottom of the pond. This not only consumes a large amount of dissolved oxygen in the water, but also produces harmful substances such as ammonia nitrogen and nitrite through microbial decomposition, leading to water quality deterioration and pH imbalance, creating an aquatic environment unfavorable to the survival of farmed organisms. At the same time, the accumulated organic matter provides a breeding ground for harmful microorganisms such as Vibrio and mold, which can easily lead to the spread of diseases, increase the morbidity and mortality of farmed organisms, and directly affect the yield and quality of aquaculture.

[0003] Currently, the main methods for collecting and cleaning uneaten feed and feces in pond aquaculture include manual dredging, drainage flushing, and mobile suction pumps. Chinese patent (application number 202522006843.9) discloses a device for collecting uneaten feed and feces from the bottom of aquaculture ponds. This device includes a rectangular aquaculture pond, a moving component, an uneaten feed and feces suction component, a linkage support component, and a collection and filtration component. This design uses an electric telescopic rod and a drive screw to move the mounting base in two orthogonal directions, thereby causing the suction pump and fan-shaped suction head to move at the bottom of the aquaculture pond, allowing for targeted suction of uneaten feed and feces. The suctioned uneaten feed and feces are transported to a collection pond through a discharge pipe and hose, where they are collected and filtered through multiple layers of filters. This device achieves a certain degree of mechanized suction and cleaning of uneaten feed and feces from the pond bottom.

[0004] However, the aforementioned existing technologies still have the following shortcomings: Firstly, the device can only perform point-to-point suction of uneaten feed and feces at the bottom of the aquaculture pond, and the cleaning method is relatively simple. It cannot effectively scrape and scrub off uneaten feed and feces that are attached to the bottom and walls of the pond, so the cleaning effect is limited. Secondly, the device relies on a negative pressure suction method of extraction pump to operate, which makes it difficult to effectively absorb residual bait and feces that have been deposited for a long time and have become stuck and hardened, resulting in incomplete cleaning. Third, the device can only clean the bottom of the pond and cannot clean the pond walls at the same time. The inner walls of the aquaculture pond will also be covered with uneaten feed and feces, which will pollute the water quality in the long run. Therefore, an automatic collection, filtration and recycling device for uneaten feed and feces in pond aquaculture is needed to improve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic collection, filtration and recycling device for uneaten feed and feces in pond aquaculture, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic collection, filtration, and recycling device for uneaten feed and feces in pond aquaculture includes: The pool has a drain outlet at the bottom.

[0007] A fixed frame is installed across the water tank.

[0008] The drive unit is mounted on the fixed frame.

[0009] A connecting unit is connected to the output end of the driving unit and rotates relative to the water tank under the drive of the driving unit.

[0010] A pool bottom cleaning unit is located at the bottom of the connecting unit and cleans the inner bottom wall of the pool as the connecting unit rotates.

[0011] A pool wall cleaning unit is disposed on the connecting unit and is provided with cleaning components for cleaning the inner wall of the pool.

[0012] A collection unit, connected to the sewage outlet, is used to discharge and filter out and recycle residual bait and feces.

[0013] The drive unit synchronously drives the pool bottom cleaning unit and the pool wall cleaning unit through the connection unit.

[0014] As a preferred embodiment of the present invention, the driving unit includes a fixed circular plate fixed to the bottom of the fixed frame, a rotating ring rotatably disposed on the outer wall of the fixed circular plate, a driving motor disposed on the top of the fixed circular plate, and a driving shaft fixedly connected to the output end of the driving motor. After the driving shaft passes through the fixed circular plate, a connecting base plate is fixedly connected to its bottom, and the driving shaft is fixedly connected to the connecting unit through the connecting base plate. When the driving motor works, it drives the driving shaft to rotate, and the driving shaft transmits power to the connecting unit through the connecting base plate, thereby driving the entire cleaning device to rotate around the center of the water tank.

[0015] As a preferred embodiment of the present invention, the connecting unit includes a fixed disc fixedly connected to the bottom of the connecting base plate and two strip rods symmetrically arranged on both sides of the fixed disc and extending horizontally. Multiple connecting blocks are fixedly connected between the two strip rods to enhance the structural strength and overall stability of the strip rods. An L-shaped rod is fixedly provided at the end of each strip rod, and an auxiliary wheel is rotatably provided at the bottom of the L-shaped rod to roll in cooperation with the top edge of the pool. The auxiliary wheel rolls along the top edge of the pool, providing stable support and rotational guidance for the entire connecting unit and the cleaning units installed on it.

[0016] As a preferred embodiment of the present invention, the pool bottom cleaning unit includes a reinforcing rod fixed to the bottom of one of the linear rods, an L-shaped support plate fixed to the bottom of the reinforcing rod, and a first scraper fixed to the bottom of the L-shaped support plate. The reinforcing rod is vertically arranged, the L-shaped support plate is horizontally arranged, and the bottom of the first scraper is inclined and in contact with the inner bottom wall of the pool, for scraping off residual bait and feces deposited on the inner bottom wall of the pool when rotating with the connecting unit.

[0017] As a preferred embodiment of the present invention, the pool bottom cleaning unit further includes multiple connecting shafts rotatably mounted on the horizontal surface of the L-shaped support plate, and brush discs correspondingly fixed to the bottom of each connecting shaft. The multiple brush discs are arranged at an angle, and the bristles at the bottom of each brush disc are in contact with the inner bottom wall of the pool. The top of each connecting shaft passes sequentially upward through a connecting block and is fixedly connected to a first bevel gear. The first bevel gear is driven by the pool wall cleaning unit to rotate, thereby causing the brush discs to rotate and perform a rotating scrubbing of the inner bottom wall of the pool, achieving a secondary fine cleaning after scraping.

[0018] As a preferred embodiment of the present invention, the pool wall cleaning unit includes a fixed ring fixed to the top of the connecting base plate, a rotating ring rotatably disposed on the top of the fixed ring, and a hollow tube disposed inside the fixed ring. The side wall of the rotating ring has a through hole. The upper end of the hollow tube is fixedly connected to the bottom of the fixed ring. The hollow tube is clearance-fitted with a drive shaft, allowing the drive shaft to rotate freely inside the hollow tube. A first bevel gear is interference-fitted to the outer wall of the hollow tube. A drive rod is rotatably mounted on the through hole of the side wall of the rotating ring. A second bevel gear is fixed to one end of the drive rod that extends into the fixed ring. The second bevel gear meshes with the first bevel gear. When the rotating ring revolves around the center of the pool with the connecting unit, the second bevel gear moves along the edge of the first bevel gear, thereby causing the drive rod to rotate. The end of the drive rod that extends out of the rotating ring is connected to a cleaning component to transmit power to the cleaning component and drive its operation. The outer wall of the housing is fixedly connected to the rotating ring, so that the internal mechanism of the cleaning component can operate while revolving with the rotating ring.

[0019] The drive rod is also fitted with multiple second bevel gears, which correspond one-to-one with the first bevel gears and mesh with each other. When the drive rod rotates, the meshing transmission between the second bevel gears and the first bevel gears drives the connecting shaft to rotate, thereby driving the brush disc to rotate.

[0020] As a preferred embodiment of the present invention, the cleaning component includes a housing and a reciprocating drive mechanism disposed inside the housing. The housing has an installation cavity inside, and a movable groove communicating with the installation cavity is opened at the bottom of the housing. The bottom of the housing also has two openings communicating with the installation cavity. The two openings are symmetrically arranged about the movable groove for installing an internal gear assembly. An extension shell is provided at the top of the housing, and the extension shell has an inner cavity communicating with the installation cavity.

[0021] The reciprocating drive mechanism includes a driving gear, a driven gear meshing with the driving gear, and a half-gear coaxially fixedly mounted with the driven gear, as well as a rack slidably fitted inside the movable slot. Specifically, the driving gear is fixedly connected to one end of the drive rod that passes through the mounting cavity. Fixed shafts are rotatably connected to both sides of the inner wall of the mounting cavity, and each fixed shaft has a driven gear and a half-gear respectively with an interference fit, meaning the driven gear and half-gear are coaxially mounted and rotate synchronously. The two driven gears mesh with the two sides of the driving gear, causing them to rotate in opposite directions. The rack is slidably mounted in the movable slot, with teeth on both sides. The two half-gears are located on both sides of the rack and intermittently mesh with it. Driven by the driven gear, the two half-gears rotate synchronously in opposite directions. When the toothed portion of one half-gear meshes with the rack, the toothless portion of the other half-gear disengages from the rack, thus enabling the two half-gears to alternately drive the rack to reciprocate up and down within the movable slot. When the rack moves upward, its tip can extend into the inner cavity of the extension shell, which limits the movement of the rack and prevents dust.

[0022] As a preferred embodiment of the present invention, a connecting frame is fixedly connected to the bottom end of the rack that protrudes from the movable groove. Brush plates are fixedly installed at both ends of the bottom of the connecting frame. The bristles on the sidewalls of each brush plate are in contact with the inner wall of the pool. The side of the housing near the inner wall of the pool is arc-shaped, and a second scraper is fixed on the outer sidewall of this side. The second scraper is in contact with the inner wall of the pool. When the housing revolves around the circumference of the pool, the second scraper first scrapes off the residual bait and feces adhering to the inner wall of the pool. Then, the brush plates move up and down reciprocally under the drive of the rack to scrub the inner wall of the pool, achieving secondary fine cleaning.

[0023] As a preferred embodiment of the present invention, a mounting rod is fixed to the outer wall of the housing, and a first protective shell is provided on the mounting rod. The first protective shell is an "L"-shaped plate. Two first protective shells are symmetrically arranged on both sides of the mounting rod and cooperate to cover the mounting rod, so as to protect the drive rod and the second bevel gear and other transmission components from water splash and debris interference. One end of the mounting rod is fixedly connected to the rotating ring, so that the housing rotates synchronously with the rotating ring. A collar is fixed to the bottom of the mounting rod. The collar is clearance-fitted with the drive rod to provide rotational support for the drive rod and ensure the stable operation of the drive rod during its rotation and revolution.

[0024] As a preferred embodiment of the present invention, one end of the strip rod is fixedly connected to the outer wall of the housing by bolts, thereby realizing the fixed connection between the connecting unit and the pool wall cleaning unit, so that the two can rotate synchronously.

[0025] As a preferred embodiment of the present invention, a second protective shell is fixed to the top of the fixing frame. The second protective shell covers the outside of the drive motor and provides waterproof, dustproof and sun protection for the drive motor, thereby extending the service life of the drive motor.

[0026] Compared with the prior art, the beneficial effects of the present invention are: This invention drives the connecting unit to rotate via a drive unit, simultaneously driving the bottom cleaning unit and the wall cleaning unit to work. This allows for dual cleaning of the bottom and walls of the pond in one operation, greatly improving the automation and efficiency of pond cleaning and effectively reducing manual labor intensity. The first scraper of the bottom cleaning unit removes residual feed and feces deposited on the bottom of the pond, and the rotating brush achieves dual cleaning in conjunction with the brush plate. While the cleaning components of the wall cleaning unit revolve, the brush plate moves up and down via a reciprocating mechanism to scrub the walls. At the same time, the second scraper scrapes the walls before the brush plate, forming a dual cleaning guarantee for a more thorough cleaning effect.

[0027] This invention utilizes a clever mechanical transmission design to achieve the simultaneous driving of multiple cleaning actions by a single drive source through the conversion between revolution and rotation. Specifically, as the drive rod revolves with the rotating ring, it achieves rotation through the meshing of a second bevel gear and a fixed first bevel gear. This rotational motion drives the rack to reciprocate through the cooperation of the driving gear and the driven gear, causing the brush plate to scrub the pool wall up and down. On the other hand, it drives the brush disc to rotate and scrub the pool bottom through the meshing of the second bevel gear and the first bevel gear, thus facilitating subsequent discharge and collection operations.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] To facilitate understanding of the present invention, a more comprehensive description of the invention will be given below with reference to the accompanying drawings, and several embodiments of the invention will be provided. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the invention will be more thorough and complete.

[0032] For examples, please refer to Figure 1-10 The present invention provides a technical solution: An automatic collection, filtration and recycling device for uneaten feed and feces in pond aquaculture includes a water tank 1 pre-buried in the ground. The water tank 1 has a circular structure and a conical bottom surface inside. The conical bottom surface facilitates the accumulation of sediments towards the center of the bottom under the action of gravity. A sewage outlet is provided at the lowest point of the bottom of the water tank 1, and the sewage outlet is connected to the collection unit 9 through a pipeline.

[0033] A fixed frame 2 is installed across the water tank 1. The two ends of the fixed frame 2 are fixed to the outer walls of opposite sides of the water tank 1. The crossbeam of the fixed frame 2 is located directly above the center of the water tank 1. A drive unit 3 is installed at the center of the fixed frame 2. The output end of the drive unit 3 is connected to a connection unit 4.

[0034] Specifically, the drive unit 3 includes a fixed circular plate 31 fixed to the bottom of the crossbeam of the fixed frame 2. The fixed circular plate 31 is a disc-shaped structure with a central shaft hole. The outer wall of the fixed circular plate 31 is rotatably connected to a rotating ring 32 via a bearing. The rotating ring 32 can rotate freely on the outer wall of the fixed circular plate 31. A drive motor 33 is fixedly installed on the top of the fixed circular plate 31. The output end of the drive motor 33 is fixedly connected to a drive shaft 34. The drive shaft 34 passes through the central shaft hole of the fixed circular plate 31 and extends downward. A connecting base plate 35 is fixedly connected to the bottom end of the drive shaft 34. The connecting base plate 35 is a horizontal circular plate. The drive shaft 34 is fixedly connected to the center of the connecting base plate 35. When the drive motor 33 is working, the drive shaft 34 drives the connecting base plate 35 to rotate around its axis.

[0035] The connecting unit 4 includes a fixed disk 42 that is fixedly connected to the bottom of the connecting base plate 35. The fixed disk 42 is a disk-shaped structure, and its center is fixedly connected to the center of the connecting base plate 35. Two horizontally arranged strip rods 41 are symmetrically fixedly connected to both sides of the fixed disk 42. The two strip rods 41 are parallel to each other and extend outward along the radial direction of the fixed disk 42. Multiple spaced connecting blocks 45 are fixedly connected between the two strip rods 41. The connecting blocks 45 are used to enhance the connection strength between the two strip rods 41 and ensure the structural stability and rigidity of the entire connecting unit 4 during rotation. Each strip rod 41 is fixedly connected to an L-shaped rod 43 at its end. The L-shaped rod 43 has an "L" shaped bending structure. Its vertical part is fixedly connected to the strip rod 41, and its horizontal part extends towards the edge of the pool 1. An auxiliary wheel 44 is rotatably installed at the bottom of the horizontal part of the L-shaped rod 43 through a rotating shaft. The wheel surface of the auxiliary wheel 44 contacts the edge of the top of the pool 1 and can roll along it. The auxiliary wheel 44 plays a supporting and guiding role when the entire connecting unit 4 rotates, ensuring that the connecting unit 4 rotates smoothly around the center of the pool 1.

[0036] One of the strip rods 41 has a bottom cleaning unit 5 fixedly connected to its bottom. The bottom cleaning unit 5 includes a reinforcing rod 51 fixed to the bottom of the strip rod 41. The reinforcing rod 51 is a vertically arranged rod, the upper end of which is fixedly connected to the strip rod 41. An L-shaped support plate 52 is fixedly connected to the bottom of the reinforcing rod 51. The L-shaped support plate 52 is an inverted "L" shaped bent plate. A first scraper 53 is fixedly connected to the bottom of the L-shaped support plate 52. The bottom of the first scraper 53 is inclined, and this inclined surface is in contact with the conical inner bottom wall of the pool 1. When the strip rod 41 drives the bottom cleaning unit 5 to rotate around the center of the pool 1, the inclined bottom surface of the first scraper 53 scrapes away the residual bait and feces deposited on the inner bottom wall of the pool 1, causing the sediment to detach from the bottom of the pool.

[0037] A connecting shaft 54 ​​is rotatably mounted on the horizontal surface of the L-shaped support plate 52 via bearings. Multiple connecting shafts 54 can be provided, and they are arranged at intervals along the extension direction of the L-shaped support plate 52. A brush disc 55 is fixedly connected to the bottom of each connecting shaft 54. The disc surface of each brush disc 55 matches the taper of the inner bottom wall of the water tank 1 and is arranged at an angle. The bristles at the bottom of the brush disc 55 are in contact with the inner bottom wall of the water tank 1. The top of each connecting shaft 54 ​​passes upward through the corresponding connecting block 45 and is fixedly connected to a first bevel gear 56. The first bevel gear 56 is used for transmission connection with the pool wall cleaning unit 6 to obtain rotational power.

[0038] The pool wall cleaning unit 6 includes a fixed ring 61 fixed to the top of the connecting base plate 35. The fixed ring 61 has a circular structure, and its center line coincides with the axis of the drive shaft 34. A rotating ring 62 is rotatably connected to the top of the fixed ring 61 via a bearing. The rotating ring 62 has a circular structure and a through hole on its side wall. The rotating ring 62 and the fixed ring 61 are concentrically arranged and can rotate relative to each other.

[0039] A hollow tube 63 is disposed at the center of the fixed ring 61. The hollow tube 63 is a tubular structure, and its upper end is fixedly connected to the bottom of the fixed circular plate 31. The hollow tube 63 is sleeved on the outside of the drive shaft 34 and is clearance-fitted with the drive shaft 34, allowing the drive shaft 34 to rotate freely inside the hollow tube 63 without contact. A first bevel gear 64 is fixedly mounted on the lower part of the outer wall of the hollow tube 63 by an interference fit. The axis of the first bevel gear 64 coincides with the axis of the hollow tube 63, meaning that the first bevel gear 64 is fixed in place.

[0040] A drive rod 66 is rotatably mounted on the through hole of the side wall of the rotating ring 62 via a bearing. The drive rod 66 is arranged in the horizontal direction. One end of the drive rod 66 extends into the interior of the fixed ring 61 and is fixedly connected to the second bevel gear 65. The tooth surfaces of the second bevel gear 65 and the first bevel gear 64 mesh with each other. The other end of the drive rod 66 passes through the rotating ring 62 and extends in the direction of the connecting unit 4.

[0041] One end of the drive rod 66, extending out of the rotating ring 62, is connected to a cleaning assembly 67. The cleaning assembly 67 has a housing 671, inside which a reciprocating drive mechanism is installed. A mounting rod 68 is fixedly connected to the outer wall of the housing 671 near the rotating ring 32, and the other end of the mounting rod 68 is fixedly connected to the rotating ring 32, so that the housing 671 rotates synchronously with the rotating ring 32, that is, the housing 671 revolves around the center of the water tank 1 with the connecting unit 4. A collar 681 is fixedly connected to the bottom of the mounting rod 68. The collar 681 is fitted around the outside of the drive rod 66 and has a clearance fit with the drive rod 66. The collar 681 provides rotational support for the drive rod 66, ensuring the stability of the drive rod 66 during rotation.

[0042] Multiple second bevel gears 69 are fixedly mounted on the outer wall of the drive rod 66 by interference fit. The number and position of the second bevel gears 69 correspond one-to-one with the first bevel gears 56 in the pool bottom cleaning unit 5. Each second bevel gear 69 meshes with its corresponding first bevel gear 56. When the drive rod 66 rotates, the meshing transmission between the second bevel gears 69 and the first bevel gears 56 drives the connecting shaft 54 ​​to rotate, thereby driving the brush disc 55 to rotate.

[0043] The housing 671 of the cleaning component 67 has an internal mounting cavity 6711. A movable groove 6712 communicating with the mounting cavity 6711 is formed at the bottom of the housing 671; the movable groove 6712 is a vertically extending slot. Two openings 6713 communicating with the mounting cavity 6711 are also formed at the bottom of the housing 671. The two openings 6713 are located on either side of the movable groove 6712 and are symmetrically arranged about the groove. An extension shell 672 is fixedly connected to the top of the housing 671. The extension shell 672 has an internal cavity communicating with the mounting cavity 6711 and is located directly above the movable groove 6712.

[0044] A driving gear 673 is fixedly connected to one end of a driving rod 66 penetrating into a mounting cavity 6711, a fixed shaft is rotatably connected to each of two sides of an inner wall of the mounting cavity 6711, the two fixed shafts are respectively rotatably mounted on front and rear side walls of a housing 671 through bearings, a driven gear 674 and a half gear 675 are respectively mounted on each fixed shaft through interference fit, and the driven gear 674 and the half gear 675 are coaxially arranged and rotate synchronously. The two driven gears 674 are respectively meshed with two sides of the driving gear 673, and when the driving gear 673 rotates, the two driven gears 674 reversely rotate synchronously. A rack 676 is slidably mounted in a movable groove 6712, teeth are arranged on both sides of the rack 676, the two half gears 675 are respectively located on two sides of the rack 676, and both the two half gears 675 are intermittently meshed with the teeth on two sides of the rack 676. Specifically, when a toothed part of the half gear 675 on one side is meshed with the rack 676, the rack 676 is pushed to move upward or downward, and at this time, a non-toothed part of the half gear 675 on the other side is disengaged from the rack 676; as the half gear 675 continues to rotate, the toothed part of the half gear 675 on the current side is disengaged from meshing, and the toothed part of the half gear 675 on the other side enters meshing to push the rack 676 to move reversely. Through alternate driving of the two half gears 675, continuous up-and-down reciprocating movement of the rack 676 in the movable groove 6712 is realized. When the rack 676 moves upward, the top end of the rack extends into an inner cavity of an extension housing 672, and the extension housing 672 plays a role in limiting movement of the rack 676 and preventing dust.

[0045] A connecting frame 677 is fixedly connected to the bottom end of the rack 676 penetrating out of the movable groove 6712, and the connecting frame 677 is a U-shaped or 冂-shaped frame structure. Brush plates 678 are respectively fixedly arranged at two ends of the bottom of the connecting frame 677, each brush plate 678 is of a plate-shaped structure, bristles are planted on a side surface of the brush plate facing the inner side wall of the water tank 1, and the bristles are in contact with the inner side wall of the water tank 1. One side of the housing 671 close to the inner side wall of the water tank 1 is arranged into an arc structure so as to better fit the radian of the inner side wall of the water tank 1, a second scraper 679 is fixedly mounted on an outer side wall of the housing 671 on the side, and a scraping edge of the second scraper 679 is in contact with the inner side wall of the water tank 1.

[0046] One end of a strip-shaped rod 41 close to a tank wall cleaning unit 6 is fixedly connected to an outer side wall of the housing 671 through a bolt, so that a connecting unit 4 and a cleaning assembly 67 form a rigid connection, and the two move synchronously in the circumferential direction of the water tank 1.

[0047] First protection shells 7 are symmetrically fixed on two sides of a mounting rod 68, each first protection shell 7 is an L-shaped bent plate, the two first protection shells 7 are relatively buckled from two sides, and are cooperatively covered outside the mounting rod 68, covering and protecting transmission components such as the mounting rod 68, the exposed part of the driving rod 66, a second bevel gear 69 and a first bevel gear 56 inside, so as to prevent water splashing and foreign matter intrusion from affecting normal operation of the transmission components.

[0048] The top of the mounting bracket 2 is fixed with a second protective shell 8. The second protective shell 8 is a box structure that covers the outside of the drive motor 33 and provides waterproof, dustproof and sun protection for the drive motor 33.

[0049] The collection unit 9 is connected to the sewage outlet at the bottom of the pool 1 via a pipeline. It is used to automatically discharge the cleaned residual feed and feces from the pool 1 and filter and recycle them. Specifically, the collection unit 9 includes a suction pump, a filter screen box, and a collection container connected in sequence via a pipeline. The suction pump, filter screen box, and collection container are all conventional existing equipment in the fields of aquaculture and water treatment. Their specific structure and selection can be directly determined by those skilled in the art based on the actual aquaculture scale and treatment volume, and will not be described in detail here.

[0050] The workflow of this invention is as follows: Start the drive motor 33. The output end of the drive motor 33 drives the drive shaft 34 to rotate. The drive shaft 34 drives the fixed disk 42 to rotate through the connecting base plate 35. The fixed disk 42 drives the two strip rods 41 to make circular motion around the center of the water tank 1. The auxiliary wheel 44 at the end of the strip rod 41 rolls along the edge of the top of the water tank 1, providing stable support and guidance for the entire rotating part.

[0051] When the bar rod 41 rotates, it drives the bottom cleaning unit 5 to move synchronously. The reinforcing rod 51 fixed to the bottom of the bar rod 41 drives the L-shaped support plate 52 to rotate around the center of the pool 1. The first scraper 53 at the bottom of the L-shaped support plate 52 moves with it and scrapes away the residual bait and feces deposited on the bottom wall of the pool 1, so that the sediment is removed from the bottom of the pool.

[0052] Meanwhile, the bar rod 41 is fixedly connected to the housing 671 by bolts, driving the cleaning assembly 67 to revolve synchronously around the center of the pool 1. Since the drive rod 66 is installed on the rotating ring 62 at the top of the fixed ring 61 through the rotating ring 62, and the fixed ring 61 is fixed on the connecting base plate 35, the second bevel gear 65 at the end of the drive rod 66 is in constant mesh with the first bevel gear 64 fixed on the hollow tube 63. When the rotating ring 62 revolves with the bar rod 41, the second bevel gear 65 moves along the edge of the first bevel gear 64. Since the first bevel gear 64 is fixed, the second bevel gear 65 rotates during the movement, thereby driving the drive rod 66 to rotate around its own axis.

[0053] The rotation of drive lever 66 generates power output in two directions: Firstly, the end of the drive rod 66 that penetrates into the housing 671 of the cleaning assembly 67 drives the drive gear 673 to rotate. The drive gear 673 drives the two driven gears 674 meshing with it on both sides to rotate synchronously in opposite directions. The two driven gears 674 respectively drive the coaxial half gears 675 to rotate synchronously in opposite directions. The two half gears 675 alternately mesh with the teeth on both sides of the rack 676, driving the rack 676 to continuously move up and down in the movable groove 6712. The rack 676 drives the brush plate 678 to move up and down through the connecting frame 677. The bristles on the side wall of the brush plate 678 scrub the inner side wall of the pool 1, removing residual bait and feces adhering to the pool wall. Meanwhile, during the revolution of the housing 671, the second scraper 679 fixed on the outer wall of the housing 671 first passes through the inner wall of the pool 1 and scrapes the pool wall once. Then the bristles of the brush 678 brush the same area a second time, forming a dual cleaning mode of scraping first and then brushing, which greatly improves the cleaning effect of the pool wall.

[0054] Secondly, as the drive rod 66 rotates, it drives the second bevel gear 69, which is interference-fitted with it, to rotate. The second bevel gear 69 meshes with the first bevel gear 56, transmitting power to the connecting shaft 54. The connecting shaft 54 ​​drives the brush disc 55 at the bottom to rotate, and the bristles at the bottom of the brush disc 55 rotate and scrub the bottom wall of the pool 1. In this way, the first scraper 53 first scrapes the bottom of the pool, and then the bristles of the brush disc 55 scrub the same area a second time, forming a dual cleaning mode of scraping followed by brushing, which effectively improves the cleaning effect of the pool bottom.

[0055] During the above process, the drive unit 3, through the connecting unit 4, simultaneously drives the bottom cleaning unit 5 and the wall cleaning unit 6 to perform a comprehensive and continuous cleaning operation on the inner bottom and inner side walls of the pool 1. The cleaned-off uneaten food and feces are carried by the water flow to the conical bottom surface of the pool 1 and finally discharged from the pool 1 through the sewage outlet. The collection unit 9 sucks up, separates solids and liquids, and filters and recycles the discharged water containing uneaten food and feces, realizing the resource utilization of uneaten food and feces.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
