[0002] In factory farming, water quality is one of the most basic environmental factors in fish farming and one of the main factors affecting fish growth. Various factors in the water will affect the growth and health of fish. In addition, changes in water quality will also affect the appetite and activity of fish. Therefore, keeping the water clean and stable is the key to fish farming.

[0003] In order to keep the water clean in modern aquaculture, the fish pond side box filter is cleaned regularly. The traditional cleaning method uses a handheld tool or a high-pressure water gun to clean the dirt in the fish pond side box filter. This operation is time-consuming and laborious, and the cleaning is not thorough, and it is easy to damage the fish pond side box filter. There are some existing fish pond side box filter cleaning devices, which use a motor-driven belt to drive the cleaning device to automatically clean the filter. However, since the belt is immersed in water for a long time, it is easy to deform the belt and cause slipping, resulting in poor cleaning effect. Summary of the invention

[0004] The purpose of the present invention is to provide a novel automatic cleaning device for fish pond side boxes, which can automatically clean the fish pond side boxes, and has high cleaning efficiency and good cleaning effect.

The two synchronous wheels are respectively mounted on the lower ends of the two transverse sliding rods, and the synchronous belt is arranged around the motor, the tensioning mechanism, the two upper pulleys, the two synchronous wheels, and the two sliding bearings. After the synchronous belt passes through the motor and the tensioning mechanism, it is first sleeved downward through the two upper pulleys, then sleeved downward through the two synchronous wheels, and then upward through the two bearings to form a closed loop; the brush fixing mechanism includes two independent sliding mounting blocks and a belt clamp, the sliding mounting block is slidably mounted on the longitudinal sliding rod, and a raised mounting platform is provided on each sliding mounting block, the belt clamp is mounted on the mounting platform, the belt clamp clamps the synchronous belt, and the brush module is mounted on the two sliding mounting blocks.

[0006] Furthermore, the mounting frame is an inverted T-shaped structure, the mounting frame extends toward the inner side of the cleaning frame, and the sliding bearing is mounted on the mounting frame so that the sliding bearing and the upper pulley are staggered to form a certain interval.

[0008] Furthermore, the sliding mounting block has the same structure as the first mounting block, and also has a mounting groove and a through groove arranged in the vertical direction. The longitudinal sliding rod passes through the through groove so that the sliding mounting block is connected to the longitudinal sliding rod, and the sliding mounting block can move on the longitudinal sliding rod.

[0009] Furthermore, the installation grooves of the two sliding installation blocks are arranged opposite to each other, and a connecting rod is inserted between the two installation grooves.

[0010] Furthermore, the belt clamp includes a toothed clamp block and a flat clamp block, the toothed clamp block is fixed on the mounting table, the toothed clamp block is provided with serrations, the size of the serrations matches the serrations of the synchronous belt, the synchronous belt passes between the toothed clamp block and the flat clamp block, the teeth of the toothed clamp block are connected to the synchronous belt to achieve a stable connection effect, and the flat clamp block is fixed to the toothed clamp block by bolts.

[0013] A novel cleaning method for a fish pond side box automatic cleaning device comprises the following steps: 1. The motor starts. When the motor rotates forward, the first and fourth synchronous belts move downward, and the second and third synchronous belts move upward. At this time, the sliding mounting block drives the brush to move downward. When the sliding mounting block drops to the lower sensor position, the lower sensor sends a signal to the motor, the motor stops and rotates in the reverse direction, and the brush drops to the bottom position. 2. When the motor rotates in the reverse direction, the first synchronous belt and the fourth synchronous belt move upward, and the second synchronous belt and the third synchronous belt move downward.

A driving wheel 211 is installed at the driving end of the motor 21, and the synchronous belt 25 is sleeved on the driving wheel 211. The driving wheel 211 is provided with a tooth shape, and the tooth shape is meshed with the tooth shape of the inner circumference of the synchronous belt 25. The driving wheel 211 is used to drive the synchronous belt 25 to rotate; the tensioning mechanism 5 includes a first guide wheel 51, a tensioning wheel 52, an adjusting rod 53 and an adjusting block 54, the first guide wheel 51 is installed on the first mounting hole 151, and the first guide wheel 51 is located at the lower left of the driving wheel 211, one end of the adjusting rod 53 is installed on the second mounting hole 152 through a rotating shaft, and the adjusting rod 53 can rotate with the rotating shaft as the axis, and the adjusting block 54 is installed on the third mounting hole 153, and the adjusting block 54 is upwardly curved The arc-shaped block structure has an arc-shaped slide groove 541 in the middle. The other end of the adjusting rod 53 is movably installed in the slide groove 541 through a rotating shaft and is fixed at different positions in the slide groove 541 by bolts. One end of the adjusting rod 53 can rotate around the rotating shaft, and the other end can be fixed at any position in the slide groove 541 by a locking mechanism such as bolts. The tensioning wheel 52 is installed at one end of the adjusting rod 53 located in the slide groove 541. The tensioning wheel 52 can move in the slide groove 541 with the adjusting rod 53. The synchronous belt 25 passes through the first guide wheel 51, the driving wheel 211 and the tensioning wheel 52 respectively. By adjusting the position of the tensioning wheel 52, when the tensioning wheel 52 moves downward, the distance between the tensioning wheel 52 and the driving wheel 211 increases, and the synchronous belt 25 is tightened, thereby achieving the function of adjusting the tension of the synchronous belt 25.

[0019] The two upper pulleys 22 are respectively mounted on the two second mounting blocks 112, and the upper pulley 22 can rotate in both directions. A mounting frame 114 is provided on the second mounting block 112, and the mounting frame 114 is an inverted T-shaped structure. The mounting frame 114 extends toward the inner side of the cleaning frame 1, and the sliding bearing 24 is mounted on the mounting frame 114, so that the sliding bearing 24 and the upper pulley 22 are staggered to form a certain interval. The two synchronous wheels 23 are respectively mounted on the lower ends of the two transverse sliding rods 11, and the size of the synchronous wheels 23 is consistent with that of the upper pulley 22. The synchronous belt 25 is arranged around the motor 21, the tensioning mechanism 5, the two upper pulleys 22, the two synchronous wheels 23, and the two sliding bearings 24. After the synchronous belt 25 passes through the motor 21 and the tensioning mechanism 5, it is first sleeved downward through the two upper pulleys 22, then sleeved downward through the two synchronous wheels 23, and then passed upward The two bearings 24 form a closed loop. When the motor 21 rotates, it can drive the synchronous belt 25 to rotate between the tensioning mechanism 5, the upper pulley 22, the synchronous wheel 23 and the sliding bearing 24. To further illustrate the motion trajectory of the synchronous belt 25, the synchronous belt 25 between the two upper pulleys 22 and the two synchronous wheels 23 is marked as the first synchronous belt 251 and the second synchronous belt 252, respectively, and the synchronous belt 25 between the two synchronous wheels 23 and the two sliding bearings 24 is marked as the third synchronous belt 253 and the fourth synchronous belt 254, respectively. When the motor 21 rotates forward, the first synchronous belt 251 and the fourth synchronous belt 254 both move upward, and the second synchronous belt 252 and the third synchronous belt 253 move downward; conversely, when the motor 21 rotates reversely, the first synchronous belt 251 and the fourth synchronous belt 254 both move downward, and the second synchronous belt 252 and the third synchronous belt 253 both move upward.

[0020] The brush fixing mechanism 3 is used to install the brush module 4. The brush fixing mechanism 3 includes two independent sliding mounting blocks 31 and a belt clip 32. Figure 7The cam 312 is a block 314 of the embodiment of the present invention, and the ... The serrations of the synchronous belt 25 match, and the synchronous belt 25 passes between the tooth clamp block 321 and the flat clamp block 322. The tooth clamp block 321 is toothed on the synchronous belt 25 to achieve a stable connection effect. The flat clamp block 322 is fixed to the tooth clamp block 321 by bolts, so that the synchronous belt 25 is fixed to the belt clamp 32. The firmness of the connection between the belt clamp 32 and the synchronous belt 25 can be ensured by the bolt connection. Since there is only one synchronous belt 25 and one motor 21, in order to realize the synchronous up and down movement of the two sliding mounting blocks 31, one sliding mounting block 31 is installed on the second synchronous belt 252, and the other sliding mounting block 31 is installed on the third synchronous belt 253, and the two sliding mounting blocks 31 are installed at the same height. When the motor 21 rotates, since the second synchronous belt 252 and the third synchronous belt 253 are in the same direction and move synchronously, the two sliding mounting blocks 31 can realize synchronous movement, and the brush module 4 can also move up and down under the drive of the two sliding mounting blocks 31.

[0021] In order to realize the automatic reciprocation of the motor 21, Figure 1 As shown, an upper sensor 33 and a lower sensor 34 are provided in the cleaning frame 1, wherein the upper sensor 33 is installed at the upper end of the inner wall of the side box 10, and the lower sensor 34 is installed at the lower end of the inner wall of the side box 10. The upper sensor 33 and the lower sensor 34 are arranged at the maximum stroke of the sliding mounting block 31, and the upper sensor 33 and the lower sensor 34 are both electrically connected to the motor 21. When the sliding mounting block 31 reaches the position of the upper sensor 33, the upper sensor 33 sends a signal to the motor 21, and the motor 21 rotates in the reverse direction. When the sliding mounting block 31 reaches the position of the lower sensor 34, the lower sensor 34 sends a signal to the motor 21, and the motor 21 moves in the reverse direction again, and so on.

[0022] The brush module 4 includes two connecting plates 41 and a brush 42. The connecting plate 41 is installed on the sliding mounting block 31. A mounting groove is provided at the front end of the connecting plate 41. The brush 42 is installed on the mounting groove. The brush 42 is used to clean the filter screen of the side box. Since the entire brush module 4 is installed on the sliding mounting block 31, and the sliding mounting block 31 is fixed on the synchronous belt 25, when the synchronous belt 25 moves up and down, it can drive the brush 42 to move up and down. The brush 42 and the filter screen generate friction to remove dirt adhering to the filter screen. The dirt is discharged into the sewage pool or discharged along the water flow, thereby realizing the cleaning of the filter screen of the side box.

[0023] The method of use of the present invention is as follows: 1. The motor 21 is started. When the motor 21 rotates forward, the first synchronous belt 251 and the fourth synchronous belt 254 move downward, and the second synchronous belt 252 and the third synchronous belt 253 move upward. At this time, the sliding mounting block 31 drives the brush 42 to move downward. When the sliding mounting block 31 drops to the position of the lower sensor 34, the lower sensor 34 sends a signal to the motor 21, and the motor 21 stops and rotates in the reverse direction. At this time, the brush 42 drops to the bottom position; 2. When the motor 21 rotates in the reverse direction, the first synchronous belt 251 and the fourth synchronous belt 254 move upward, and the second synchronous belt 252 and the third synchronous belt 253 move downward. At this time, the sliding mounting block 31 drives the brush 42 to move upward. When the sliding mounting block 31 rises to the position of the lower sensor 34, the upper sensor 33 sends a signal to the motor 21, and the motor 21 stops and rotates in the reverse direction. At this time, the brush 42 rises to the topmost position, and so on. The brush 42 and the filter screen generate friction to remove the dirt adhering to the filter screen, and the dirt is discharged into the sewage pool or discharged along the water flow, thereby realizing the cleaning of the filter screen of the opposite box; 3. When the synchronous belt 25 becomes loose, adjust the position of the adjusting rod 53 in the slide groove 541 downward and fix it, so that the distance between the tensioning wheel 52 and the driving wheel 211 increases, the synchronous belt 25 is tightened, and the tension of the synchronous belt 25 increases, ensuring that the synchronous belt 25 can drive the brush module 4 to operate normally.

[0024] The present invention has a simple structure and a reasonable design. A reciprocating module is arranged to control a brush module to automatically clean the filter screen of the fish pond side box. The present invention has a high degree of automation and a good cleaning effect. It can replace manual cleaning, which can not only free up manpower and improve efficiency, but also prevent the occurrence of potential risks. At the same time, a tensioning mechanism is used to timely adjust the tension of the synchronous belt to ensure the cleaning effect. The equipment generates almost no noise during operation and does not cause large splashes, which can greatly reduce the damage to fish caused by improper cleaning.

[0025] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.

The novel automatic cleaning device for the side box of a fish pond according to claim 1 is characterized in that: An upper sensor (33) and a lower sensor (34) are arranged in the cleaning frame (1), wherein the upper sensor (33) is mounted on the upper end of the inner wall of the side box (10), and the lower sensor (34) is mounted on the lower end of the inner wall of the side box (10). The upper sensor (33) and the lower sensor (34) are arranged at the maximum stroke of the sliding mounting block (31), and the upper sensor (33) and the lower sensor (34) are both electrically connected to the motor (21).

9. A cleaning method of the novel automatic cleaning device for the side box of a fish pond according to any one of claims 1 to 8, characterized in that: The following steps are involved: (1) The motor (21) is started. When the motor (21) rotates in the forward direction, the first synchronous belt (251) and the fourth synchronous belt (254) move downward, and the second synchronous belt (252) and the third synchronous belt (253) move upward. At this time, the sliding mounting block (31) drives the brush (42) to move downward. When the sliding mounting block (31) descends to the position of the lower sensor (34), the lower sensor (34) sends a signal to the motor (21), and the motor (21) stops and rotates in the reverse direction. At this time, the brush (42) descends to the bottom position; (2) When the motor (21) rotates in the reverse direction, the first synchronous belt (251) and the fourth synchronous belt (254) move upward, and the second synchronous belt (252) and the third synchronous belt (253) move downward. At this time, the sliding mounting block (31) drives the brush (42) to move upward. When the sliding mounting block (31) rises to the position of the lower sensor (34), the upper sensor (33) sends a signal to the motor (21), and the motor (21) stops and rotates in the reverse direction. At this time, the brush (42) rises to the topmost position. In this way, the brush (42) and the filter screen generate friction to remove dirt adhering to the filter screen. The dirt is discharged into the sewage pool or discharged along the water flow, thereby cleaning the filter screen of the opposite box; (3) When the synchronous belt (25) becomes loose, the tensioning mechanism can be adjusted to adjust the tension of the synchronous belt (25). The tensioning mechanism (5) comprises a first guide wheel (51), a tensioning wheel (52), an adjusting rod (53) and an adjusting block (54). The first guide wheel (51), the adjusting rod (53) and the adjusting block (54) are all mounted on the mounting seat (15). The first guide wheel (51) is located at the lower left of the driving wheel (211). One end of the adjusting rod (53) is mounted on the mounting seat (15) via a rotating shaft. The adjusting rod (53) can rotate around the rotating shaft. The adjusting block (54) is an upwardly curved block structure. A curved sliding groove (541) is provided in the middle. The other end of the adjusting rod (53) is connected to the mounting seat (15) via a rotating shaft. The rotating shaft is movably installed in the slide groove (541) and is fixed at different positions in the slide groove (541) by bolts. One end of the adjusting rod (53) can rotate with the rotating shaft as the axis, and the other end can be fixed at any position in the slide groove (541) by a locking mechanism such as a bolt. The tensioning wheel (52) is installed at one end of the adjusting rod (53) located in the slide groove (541). The tensioning wheel (52) can move in the slide groove (541) along with the adjusting rod (53). When adjusting, the position of the adjusting rod (53) in the slide groove (541) is adjusted downward and fixed, so that the distance between the tensioning wheel (52) and the driving wheel (211) increases, the synchronous belt (25) is tightened, and the tension of the synchronous belt (25) increases, thereby ensuring that the synchronous belt (25) can drive the brush module (4) to operate normally.
