Description

Technical Field

[0001] This invention belongs to the technical field of capture net storage devices, and particularly relates to a capture net anti-knotting storage device. Background Technology

[0002] The net storage device is a specialized storage tool designed for fishing nets, insect nets, and other net-like tools. It aims to solve problems associated with traditional storage methods, such as tangling, large space occupation, and inconvenience in carrying. The core design of the net storage device is based on a modular structure and easy operation. Through mechanical transmission, folding structures, or magnetic fixing technologies, it enables the rapid deployment and compact storage of nets.

[0003] For example, an existing fishing net storage rack with publication number CN112913795B specifically discloses a second connecting rod whose first end is connected to the second end of the first connecting rod, a fourth support rod whose first end is vertically connected to the first connecting rod, a fifth support rod whose first end is located inside the cavity of the fourth support rod, a sixth support rod located directly above the fourth support rod, a second support rod whose first end is located inside the cavity of the first support rod, a third support rod sleeved onto the second end of the second support rod, a third connecting rod whose first end is fixedly connected to the second end of the sixth support rod, and a fifth connecting rod slidably connected to the second end of the fifth support rod. This invention has a reasonable design and simple structure. Sliding the second and third support rods allows adjustment of the height of the third and fourth connecting rods, and also allows for the sliding of the sixth connecting rod.

[0004] Existing net retrieval devices often experience net tangling within the storage chamber. This tangling requires manual untying of each knot, which can be problematic, especially in emergency situations (such as rapid fishing or scientific sampling), potentially leading to target escape or data loss due to delays. For instance, when fishermen are working at night, every minute spent untying the net could cause them to miss the optimal fishing window. Therefore, designing an anti-tangling net retrieval device is essential to address these issues. Summary of the Invention

[0005] This invention provides a device for preventing knotting and storing capture nets, aiming to solve the problem that capture nets tend to get knotted inside the storage cavity of current capture net storage devices, causing delays and wasting time.

[0006] The present invention is implemented as follows: a device for preventing knotting and storing a capture net includes a base, on which multiple vertical plates are arranged at equal intervals. Each vertical plate is provided with a storage mechanism for storing the capture net. The storage mechanism includes a rotating shaft rotatably mounted on the vertical plate, and a storage rod is fixedly installed at one end of the rotating shaft. The annular ring above the capture net passes through the storage rod.

[0007] A limiting plate is fixedly installed at one end of the storage rod, and a gathering mechanism is provided at the upper end of the storage rod. The gathering mechanism is used to gather the capture nets together. The gathering mechanism includes a spline sleeve rotatably installed on a vertical plate. An inner spline groove is provided inside the spline sleeve. A turntable is fixedly installed at one end of the spline sleeve. The turntable is rotatably installed on the vertical plate. An outer spline shaft is inserted into one end of the spline sleeve. The outer spline shaft is slidably installed on the spline sleeve and the two are spline-fitted. A push plate is fixedly installed at one end of the outer spline shaft. A through hole is opened on the push plate. The through hole matches the shape of the storage rod.

[0008] As a preferred embodiment, the collecting mechanism further includes a connecting plate mounted on the external spline shaft. The connecting plate is rotatably mounted on the external spline shaft, and the external spline shaft passes through the connecting plate. A linear motor is fixedly mounted on the vertical plate, and a connecting piece is fixedly mounted on the movable block of the linear motor. The connecting piece is fixedly connected to the connecting plate.

[0009] As a preferred embodiment, a reciprocating swing mechanism is installed on the vertical plate, and the reciprocating swing mechanism is connected to multiple storage rods. The reciprocating swing mechanism is used to drive the storage rods to rotate back and forth.

[0010] As a preferred embodiment, the reciprocating oscillating mechanism includes a coil spring, which is sleeved on the outside of the rotating shaft. The inner and outer ends of the coil spring are respectively fixedly connected to the rotating shaft and the vertical plate. A driven wheel is fixedly installed at the other end of the rotating shaft. A transmission shaft is rotatably installed on each of the vertical plates. An incomplete gear is fixedly installed on the transmission shaft. A pulley is fixedly installed at the end of each transmission shaft. A synchronous belt is installed between the multiple pulleys, and the multiple pulleys are driven by the synchronous belt. A servo motor is fixedly installed on the vertical plate, and the output shaft of the servo motor is fixedly connected to one of the pulleys.

[0011] As a preferred embodiment, a tensioning block is provided on one side of the vertical plate, the tensioning block presses on the synchronous belt and makes the synchronous belt fit tightly against the pulley, a guide rod is fixedly installed on the tensioning block, and two elastic strips are fixedly connected between the tensioning block and the vertical plate.

[0012] As a preferred embodiment, each of the storage rods is provided with two spaced support plates. The support plates are configured as continuous bends and are used to place the capture net and perform drying treatment. The base is provided with several evenly distributed permeable grooves. The base is hollow inside and open at both ends. The permeable grooves are connected to the hollow cavity inside the base.

[0013] As a preferred embodiment, the storage rod is hollow inside, and a number of evenly distributed ventilation holes are opened on the surface of the storage rod. The storage rod is connected to the exhaust pipe of an external air pump.

[0014] As a preferred embodiment, the base is provided with a protective pad at the bottom.

[0015] As a preferred embodiment, a shaking mechanism is provided on the side of the support plate, which is used to impact the support plate and cause the capture net on the support plate to shake.

[0016] As a preferred embodiment, the shaking mechanism includes a guide frame fixedly connected to the base, a movable seat slidably mounted on the guide frame, a spring telescopic rod mounted on the movable seat, a top block mounted on the movable end of the spring telescopic rod, the top block contacting the support plate, a lead screw mounted on the movable seat, and a stepper motor fixedly mounted on the guide frame, with the output shaft of the stepper motor fixedly connected to the lead screw.

[0017] Compared with related technologies, the anti-knotting and storage device for the capture net provided by the present invention has the following beneficial effects: 1. By rotating the turntable fixedly connected to the spline sleeve, the spline sleeve can be driven to rotate. Due to the spline fit between the outer spline shaft and the spline sleeve, the outer spline shaft will rotate synchronously, thereby driving the push plate to rotate. This allows the capture net to be concentrated at a suitable angle, effectively preventing the capture net from tangling in the storage cavity. This solves the problem of delays and wasted time caused by tangled capture nets, improves overall work efficiency, and enables related operations to be performed more smoothly and promptly.

[0018] 2. By passing the ring above the capture net through the rotatable storage rod, rotating the storage rod allows the capture net to be neatly wound around it, initially completing the storage operation and facilitating subsequent processing. A linear motor drives the external spline shaft to slide, which in turn moves the push plate fixed to one end of the external spline shaft towards the storage rod, gathering the capture net stored on the storage rod to one side for a more compact storage. By passing the ring above the capture net through the storage rod and rotating the rod, the capture net is wound around it, completing the initial storage. The operation is simple and allows for quick initiation of the storage process.

[0019] 3. By starting the linear motor, the external spline shaft slides within the spline sleeve via the connecting parts and connecting plate, causing the push plate to move towards the storage rod. This gathers the capture net stored on the storage rod, making the capture net more compact and orderly, reducing clutter. Rotating the turntable drives the spline sleeve to rotate, which in turn causes the external spline shaft and push plate to rotate synchronously, gathering the capture net from a suitable angle. This effectively prevents the capture net from tangling, avoiding delays and wasted time due to tangling, and improving storage efficiency.

[0020] 4. By starting the servo motor, in conjunction with the pulley and synchronous belt drive, the incomplete gear on the drive shaft rotates, realizing the reciprocating rotation of the collection rod. This reciprocating rotation makes the capture net collect more evenly, further reducing the possibility of knotting, and at the same time, it causes the capture net to swing, allowing impurities on the capture net to fall off quickly, reducing the cleaning burden.

[0021] 5. The reciprocating rotation of the storage rod causes the capture net to swing, using the force generated by the swing to quickly remove impurities from the net, eliminating the need for frequent manual cleaning, reducing the workload and improving cleaning efficiency. The storage rod is hollow inside with ventilation holes on its surface, connecting to the exhaust pipe of an external air pump. When the air pump is working, air is blown out through the ventilation holes. The base has a water-permeable groove with openings at both ends, facilitating water drainage. These two features work together to accelerate airflow and moisture removal around the capture net, speeding up its drying process.

[0022] 6. The stepper motor drives the lead screw to rotate, and the movable seat moves along the lead screw on the guide frame. The spring telescopic rod on the movable seat drives the top block to hit the support plate, causing the support plate to vibrate. This, in turn, causes the catching net placed on the support plate to shake, accelerating moisture loss and further improving drying efficiency. Attached Figure Description

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] A preferred embodiment of the anti-knotting storage device for the capture net provided by the present invention is as follows: Figures 1 to 7 As shown: A device for preventing knotting and storing a capture net includes a base 1, on which a plurality of equally spaced vertical plates 2 are provided. Each vertical plate 2 is provided with a storage mechanism for storing the capture net. The storage mechanism includes a rotating shaft 3 rotatably mounted on the vertical plate 2. A storage rod 4 is fixedly installed at one end of the rotating shaft 3, and the annular ring above the capture net passes through the storage rod 4.

[0028] A limiting plate 5 is fixedly installed at one end of the storage rod 4. A gathering mechanism is provided at the upper end of the storage rod 4. The gathering mechanism is used to gather the capture nets together. The gathering mechanism includes a spline sleeve 6 that is rotatably installed on the vertical plate 2. The spline sleeve 6 has an inner spline groove. A turntable 7 is fixedly installed at one end of the spline sleeve 6. The turntable 7 is rotatably installed on the vertical plate 2. An outer spline shaft 8 is inserted into one end of the spline sleeve 6. The outer spline shaft 8 is slidably installed on the spline sleeve 6 and the two are splinedly engaged. A push plate 9 is fixedly installed at one end of the outer spline shaft 8. A through hole 10 is opened on the push plate 9. The through hole 10 matches the shape of the storage rod 4.

[0029] The gathering mechanism also includes a connecting plate 11 mounted on the external splined shaft 8. The connecting plate 11 is rotatably mounted on the external splined shaft 8, and the external splined shaft 8 passes through the connecting plate 11. A linear motor 12 is fixedly mounted on the vertical plate 2, and a connector 13 is fixedly mounted on the movable block of the linear motor 12. The connector 13 is fixedly connected to the connecting plate 11. The gathering mechanism is used to gather the capture nets on the collection rod 4 together.

[0030] The ring above the capture net is passed through the storage rod 4. Since the storage rod 4 is rotatably mounted on the vertical plate 2 via the pivot 3, when storing the capture net, the storage rod 4 can be rotated to make the capture net wrap around the storage rod 4 more neatly, thus initially completing the storage operation of the capture net.

[0031] When the linear motor 12 starts, its movable block drives the connecting piece 13 to move. Since the connecting piece 13 is fixedly connected to the connecting plate 11 and the connecting plate 11 is installed on the external spline shaft 8, it will drive the external spline shaft 8 to slide inside the spline sleeve 6.

[0032] A push plate 9 is fixedly installed at one end of the external spline shaft 8. The through hole 10 on the push plate 9 matches the shape of the storage rod 4. As the external spline shaft 8 slides, the push plate 9 will move towards the storage rod 4, gathering the capture net stored on the storage rod 4 to one side.

[0033] Meanwhile, the spline sleeve 6 is rotatably mounted on the vertical plate 2 and a turntable 7 is fixedly mounted on one end. During the movement of the push plate 9, if it is necessary to adjust the angle to better collect the capture net, the spline sleeve 6 can be rotated by rotating the turntable 7. Since the outer spline shaft 8 is splined with the spline sleeve 6, the outer spline shaft 8 will rotate synchronously with the rotation of the spline sleeve 6, thereby driving the push plate 9 to rotate. This allows the push plate 9 to concentrate the capture net together at a suitable angle, avoiding the capture net from getting tangled in the storage cavity. This solves the problem of delays and wasted time caused by the capture net getting tangled.

[0034] In a further preferred embodiment of the present invention: A reciprocating swing mechanism is installed on the vertical plate 2. The reciprocating swing mechanism is connected to multiple storage rods 4 and is used to drive the storage rods 4 to rotate back and forth. The reciprocating swing mechanism includes a coil spring 14, which is sleeved on the outside of the rotating shaft 3. The inner and outer ends of the coil spring 14 are fixedly connected to the rotating shaft 3 and the vertical plate 2, respectively. A driven wheel 15 is fixedly installed on the other end of the rotating shaft 3. A transmission shaft 16 is rotatably installed on each of the vertical plates 2. An incomplete gear 17 is fixedly installed on the transmission shaft 16. A pulley 18 is fixedly installed at the end of each transmission shaft 16. A synchronous belt 19 is installed between the multiple pulleys 18, and the multiple pulleys 18 are driven by the synchronous belt 19. A servo motor 23 is fixedly installed on the vertical plate 2, and the output shaft of the servo motor 23 is fixedly connected to one of the pulleys 18. A tensioning block 20 is provided on one side of the vertical plate 2. The tensioning block 20 presses on the synchronous belt 19 and makes the synchronous belt 19 fit tightly against the pulley 18. A guide rod 21 is fixedly installed on the tensioning block 20. Two elastic strips 22 are fixedly connected between the tensioning block 20 and the vertical plate 2.

[0035] Below each of the storage rods 4 are two spaced-apart support plates 24. These support plates 24 are continuously bent and are used to hold the capture net and allow it to dry. The base 1 has several evenly distributed permeable grooves 25. The base 1 is hollow inside and open at both ends, with the permeable grooves 25 communicating with the internal cavity of the base 1. The storage rod 4 is also hollow inside, with several evenly distributed air holes on its surface. The storage rod 4 is connected to the exhaust pipe of an external air pump. A protective pad is provided at the bottom of the base 1. This protective pad serves to absorb shock and prevent slippage, protecting the stability of the device during placement and use, and reducing damage caused by vibration or sliding.

[0036] A shaking mechanism is provided on the side of the support plate 24. The shaking mechanism is used to impact the support plate 24 and cause the capture net on the support plate 24 to shake. The shaking mechanism includes a guide frame 26 fixedly connected to the base 1. A movable seat 27 is slidably mounted on the guide frame 26. A spring telescopic rod 28 is mounted on the movable seat 27. A top block 29 is mounted on the movable end of the spring telescopic rod 28. The top block 29 contacts the support plate 24. A lead screw 30 is mounted on the movable seat 27. A stepper motor 31 is fixedly mounted on the guide frame 26. The output shaft of the stepper motor 31 is fixedly connected to the lead screw 30.

[0037] The ring above the capture net is passed through the storage rod 4. By rotating the storage rod 4, the capture net is initially collected by wrapping it around the rod. The linear motor 12 is started, and through the connecting piece 13 and the connecting plate 11, it drives the outer spline shaft 8 to slide inside the spline sleeve 6. The push plate 9 then moves towards the storage rod 4, gathering the capture net collected on the rod 4. The rotating turntable 7 drives the spline sleeve 6 to rotate, and the outer spline shaft 8 and the push plate 9 rotate synchronously, gathering the capture net at a suitable angle to prevent tangling.

[0038] The servo motor 23 starts, and its output shaft drives the connected pulley 18 to rotate. Through the synchronous belt 19, multiple pulleys 18 rotate synchronously, which in turn drives the transmission shaft 16 to rotate. The incomplete gear 17 on the transmission shaft 16 rotates accordingly. When the incomplete gear 17 meshes with the driven wheel 15, it drives the rotating shaft 3 to rotate, and the coil spring 14 is coiled up. When the incomplete gear 17 disengages from the driven wheel 15, the coil spring 14 releases its elastic potential energy, driving the rotating shaft 3 to rotate in the opposite direction. This cycle repeats, realizing the reciprocating rotation of the collecting rod 4, making the capture net collect more evenly and further reducing the possibility of knotting. At the same time, by driving the capture net to swing, impurities on the capture net are quickly removed from the capture net, reducing the workload of cleaning.

[0039] The tension block 20, under the action of the elastic strip 22, presses against the synchronous belt 19, ensuring that the synchronous belt 19 fits tightly against the pulley 18, thus guaranteeing the stability and reliability of the transmission. The guide rod 21 provides guidance for the movement of the tension block 20.

[0040] A continuously bent support plate 24 is installed below the storage rod 4, and the capture net is placed on the support plate 24. A water-permeable groove 25 is formed on the base 1, and the interior is hollow with openings at both ends. The storage rod 4 is hollow inside and has air vents on its surface, connecting to the exhaust pipe of an external air pump. When the air pump operates, air is blown out through the air vents of the storage rod 4, while the water-permeable groove 25 of the base 1 facilitates water drainage, accelerating the drying of the capture net.

[0041] Stepper motor 31 starts, and its output shaft drives lead screw 30 to rotate. Movable seat 27 moves along lead screw 30 on guide frame 26. Impact vibration: Spring telescopic rod 28 on movable seat 27 drives top block 29 to contact and impact support plate 24, causing support plate 24 to vibrate, which in turn causes the catching net placed on support plate 24 to shake, accelerating moisture loss and improving drying efficiency.

[0042] By rotating the turntable 7, which is fixedly connected to the spline sleeve 6, the spline sleeve 6 can be rotated. Since the outer spline shaft 8 is splined with the spline sleeve 6, the outer spline shaft 8 will rotate synchronously, thereby driving the push plate 9 to rotate. This allows the capture net to be concentrated at a suitable angle, effectively preventing the capture net from tangling in the storage cavity. This solves the problem of delays and wasted time caused by tangled capture nets, improves overall work efficiency, and makes related operations smoother and more timely.

[0043] By passing the ring above the capture net through the rotatable storage rod 4, rotating the storage rod 4 allows the capture net to be neatly wound around it, initially completing the storage operation and facilitating subsequent processing. The linear motor 12 drives the external spline shaft 8 to slide, which in turn moves the push plate 9 fixed to one end of the external spline shaft 8 towards the storage rod 4, gathering the capture net stored on the storage rod 4 to one side for a more compact storage. By passing the ring above the capture net through the storage rod 4 and rotating the storage rod 4, the capture net can be wound around it, completing the initial storage. The operation is simple and allows for a quick start to the storage process.

[0044] By starting the linear motor 12, the external spline shaft 8 is driven to slide inside the spline sleeve 6 via the connector 13 and the connecting plate 11, causing the push plate 9 to move towards the storage rod 4, thus gathering the capture net stored on the storage rod 4, making the capture net more compact and orderly, and reducing clutter.

[0045] By rotating the turntable 7, the spline sleeve 6 is driven to rotate, which in turn causes the outer spline shaft 8 and the push plate 9 to rotate synchronously. This allows the capture net to be collected from a suitable angle, effectively preventing the capture net from getting tangled and avoiding delays and wasted time due to tangling, thus improving storage efficiency.

[0046] By activating the servo motor, which works in conjunction with pulley 18 and synchronous belt 19, the incomplete gear 17 on the transmission shaft 16 rotates, thus achieving the reciprocating rotation of the collection rod 4. This reciprocating rotation makes the capture net collect more evenly, further reducing the possibility of tangling, while also causing the capture net to swing, allowing impurities on the net to fall off quickly and reducing the cleaning burden.

[0047] The reciprocating rotation of the storage rod 4 causes the capture net to swing, using the force generated by the swing to quickly remove impurities from the net, eliminating the need for frequent manual cleaning, reducing the workload and improving cleaning efficiency. The storage rod 4 is hollow inside with ventilation holes on its surface, connecting to the exhaust pipe of an external air pump. When the air pump is working, air is blown out through the ventilation holes. The base 1 has a water-permeable groove 25, which is hollow inside with openings at both ends, facilitating water drainage. These two features work together to accelerate airflow and water removal around the capture net, speeding up its drying process.

[0048] The stepper motor 31 starts and drives the lead screw 30 to rotate. The movable seat 27 moves along the lead screw 30 on the guide frame 26. The spring telescopic rod 28 on the movable seat 27 drives the top block 29 to hit the support plate 24, causing the support plate 24 to vibrate. This causes the net placed on the support plate 24 to shake, accelerating moisture loss and further improving drying efficiency.
