Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a bass farming and harvesting device. Background Technology

[0002] Currently, Chinese patent application number 202411933353.7 discloses a freshwater aquaculture fishing device, including support seats installed on both sides of a pond embankment. A pair of support seats on each side of the embankment are grouped together, with a pulley bolted to each. The pulleys on each group of support seats are connected by a rubber belt for transmission. The pulleys are driven by a trawl drive mechanism. The inner side of the rubber belt has a locking block, and the pulleys have locking grooves. The locking block can be detachably locked into the locking groove. Several mounting rings are machined on the outer surface of the rubber belt, and the trawl mechanism is suspended between two parallel groups of support seats. This invention solves the problems of low efficiency and poor automation in traditional freshwater aquaculture fishing, the inability to cover large areas of ponds, and the fixed placement of net cages, making it difficult to capture all fish in the pond at once. Existing patents, when used, only adjust the trawl depth through the length of the trawl rings, lacking precise positioning and anti-sway structures, easily leading to trawl deviation and uneven depth.

[0003] Because the bottom of aquaculture ponds is often uneven (containing silt, pits, rocks, etc.), the weights (such as lead weights) at the bottom of traditional nets are rigid or semi-rigid structures, making it difficult to completely conform to complex terrain and easily creating gaps between the net bottom and the pond bottom. This causes some fish (especially bottom-dwelling fish) to escape from the bottom of the net, resulting in yield losses; and in some large, flat aquaculture ponds, where the nets are cast directly into the pond, some fish escape from the sides of the nets, resulting in poor catch efficiency.

[0004] Existing mechanical fishing equipment is mostly passive interception, with fixed net shapes. When stationary, the nets have a large open area, easily disturbing schools of fish; when moving, they cannot dynamically adjust their shape according to water flow to optimize the trapping effect. Summary of the Invention

[0005] Therefore, in view of the above problems, the present invention proposes a bass farming and harvesting device to solve the above technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes an aquaculture pond located on a embankment, with rails installed on both sides of the pond, a drive assembly installed at one end of each rail, and a fishing device installed on the rails. A guide structure is symmetrically installed on the inner wall of the pond. The fishing device includes a movable drag plate installed on the rails, a support seat installed on the upper surface of the movable drag plate, a rotating seat installed on the surface of the support seat, a support plate connecting the rotating seats installed on the two rails, and a hook below the support plate suspending a fishing net. The fishing net is connected to the support plate via the hook and is fixedly connected with a buoy. The fishing net includes a net frame, with collars provided on both sides of the net frame at positions corresponding to the guide structure. The collars are slidably engaged with the guide structure. A graded fishing net is installed inside the net frame, and a gravity sand bar is provided at the bottom of the net frame. A silicone skirt is installed on the lower surface of the gravity sand bar. The graded fishing net includes a primary net with a No. 1 fish inlet at the front end. An escape-prevention fishing net is sewn along the edge of the No. 1 fish inlet on its inner side. A secondary net is sewn to the rear end of the primary net. The edges of the secondary net are sewn with rolled edges. A shaped frame is evenly sewn onto the surface of the secondary net. A second fish inlet is opened on the common surface of the secondary net and the primary net. An escape-prevention channel is sewn onto the inner side of the second fish inlet of the secondary net.

[0007] Furthermore, it also includes a removable anti-jump guard that can be detachably installed on the support plate. The anti-jump guard includes a mounting plate and a retractable arc-shaped protective net connected to the front surface of the mounting plate. The mounting plate and the support plate are fitted together and fixedly connected by bolts. The inner side of the arc-shaped protective net is sewn with anti-scratch fleece.

[0008] Furthermore, the edge-sealing anti-escape fishing net has a ring structure, with its open end sewn to the No. 1 fish inlet, and the other end having an open through-hole structure to allow the bass to enter the first-level net; a closing rope is sewn at the position where the edge-sealing anti-escape fishing net is sewn to the No. 1 fish inlet, and the free end of the closing rope extends through the No. 1 fish inlet to the embankment. The end of the anti-escape fishing net furthest from the No. 1 fish inlet has a silicone sand ball sewn to the upper part and a float sewn to the lower part, with the silicone sand ball and the float symmetrically distributed.

[0009] Furthermore, the rolled edges are sewn onto the top netting, bottom netting, and side netting of the secondary netting. The rolled edges are made of flexible tubing and have internal weights to ensure the secondary netting hangs naturally and maintains a stable net shape.

[0010] Furthermore, the shaping frame is a magnetic structure, and adjacent shaping frames are attracted by opposite magnetic poles. When the secondary net is stationary, it is in a contracted state due to the magnetic attraction between two adjacent shaping frames. When the fishing device moves, the magnetic attraction is overcome by the impact of the water flow, and the secondary net automatically unfolds.

[0011] Furthermore, the secondary mesh is also equipped with a flexible LED light-attracting light strip, which is configured to emit a blue-green spectrum with a wavelength between 480nm and 520nm. The light-attracting light strip has a constant light mode and a pulse flashing mode. The frequency of the pulse flashing mode is adjustable between 0.5Hz and 2Hz, which is used to simulate biological movement to induce the predatory instinct of bass. The light intensity of the light-inducing light strip can be steplessly adjusted between 300 lux and 1500 lux, and is configured to be linked with the state of the shaping frame: when the secondary mesh is in a contracted state, the light intensity is below 50 lux or emits red light; when the secondary mesh is in an unfolded state, it automatically switches to a pulse flashing mode with a blue-green spectrum.

[0012] Furthermore, the mesh size of the primary mesh is larger than that of the secondary mesh.

[0013] Furthermore, the silicone skirt is made of a flexible and wear-resistant material. When the fishing net is placed in the aquaculture pond, the silicone skirt flexibly fits the bottom of the pond. The silicone skirt has a segmented structure and is flexibly connected.

[0014] Furthermore, the mounting positions of the rotating seat and the support seat are provided with 0-90° angle adjustment seats; the support plates connecting adjacent rotating seats are rotatably connected by a rotating shaft.

[0015] Furthermore, the guide structure includes an electric push rod, a telescopic rod connected to the vertical end of the electric push rod, and a guide rod installed perpendicularly to the telescopic rod at equal intervals. The guide rod passes through a collar, and the two are fitted together in a sliding fit. The guide rod is a telescopic structure, and its extension and retraction are adapted to the width of the aquaculture pond, which can be flexibly adjusted according to the size of the aquaculture pond.

[0016] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: This invention achieves automated reciprocating motion of the fishing device through the cooperation of track bars, drive components and moving trolleys, thereby reducing the intensity of manual labor and improving the efficiency and continuity of fishing operations.

[0017] The retractable, curved protective netting with scratch-resistant fabric effectively prevents bass from jumping and escaping, providing cushioning protection to prevent head injuries and scale loss. Segmented silicone skirts at the bottom of the net frame allow it to flexibly conform to the uneven pond bottom, preventing fish from escaping due to improper fit. Furthermore, the net frame is connected to the inner wall of the pond with guide rods, ensuring the sides of the net remain firmly against the pond wall, eliminating lateral escape loopholes. The symmetrical distribution of floats and sand balls keeps the fish inlet naturally and vertically open in the water, reducing congestion and friction among the fish.

[0018] By using a combination of primary and secondary netting, with a unidirectional funnel-shaped escape-proof channel on their common surface, the automatic separation of bass of different sizes is achieved. This reduces the tedious manual secondary sorting process after traditional fishing, significantly shortens the time the fish are out of the water, and reduces stress and mortality caused by repeated handling.

[0019] Utilizing the principle of attraction between opposite poles of adjacent magnetic shaping frames, the net automatically switches between a "folded" and "deployed" state without the need for additional motors or hydraulic drives, relying solely on the impact force of the water flow during movement. When stationary, it folds up to reduce resistance and visibility, while when in operation, it deploys to maximize the fishing space. The structure is simple, reliable, and consumes very little energy. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1

[0022] refer to Figure 1 - Figure 4 as well as Figure 7 This embodiment provides a bass farming and harvesting device, which includes a farming pond 2 built on a embankment 1. In order to realize automated reciprocating motion, parallel rails 3 are installed on both sides of the farming pond 2. A drive component 4 is installed at one end of the rails 3. In this embodiment, the drive component 4 is preferably a servo motor or a variable frequency motor with a reduction mechanism. Its output end is connected to the harvesting device 5 through a chain, gear or wire rope to provide stable and adjustable traction power. A fishing device 5 is installed on the track bar 3. A guide structure 6 is symmetrically installed on the inner wall of the aquaculture pond 2. The fishing device 5 includes a movable drag plate 51 installed on the track bar 3. A support seat 52 is installed on the upper surface of the movable drag plate 51. A rotating seat 53 is installed on the surface of the support seat 52. A support plate 54 is connected between the rotating seats 53 installed on the two track bars 3. A hook is set below the support plate 54 and a fishing net 55 is suspended. The fishing net 55 is connected to the support plate 54 through the hook and is fixedly connected with a buoy 56. The buoy 56 is used to balance the gravity. The installation position of the rotating seat 53 and the support seat 52 is provided with a 0-90° angle adjustment seat. The support plate 54 connected between adjacent rotating seats 53 is rotatably connected by a rotating shaft 541. The support plate 54 can be rotated by the rotating shaft 541, so that the support plate 54 can adapt to the track height difference caused by different terrain, or adjust the tilt angle of the net during the net lifting operation to prevent jamming. The fishing net 55 includes a net frame 551. Loops 552 are provided on both sides of the net frame 551 at positions corresponding to the guide structure 6. The loops 552 slide with the guide structure 6. A graded fishing net 553 is installed inside the net frame 551. A gravity sand bar 554 is provided at the bottom of the net frame 551. A silicone skirt 555 is installed on the lower surface of the gravity sand bar 554. The graded fishing net 553 includes a primary net 5531. The primary net 5531 has a first fish inlet 5532 at its front end. An escape-prevention fishing net 5533 is sewn along the edge of the first fish inlet 5532 facing inwards. A secondary net 5534 is sewn to the rear end of the primary net 5531. A rolled edge 5535 is sewn along the edge of the secondary net 5534. A shaped frame 5536 is evenly sewn onto the surface of the secondary net 5534. A second fish inlet 5537 is located on the shared surface of the secondary net 5534 and the primary net 5531. An escape-prevention channel 5538 is sewn onto the side of the second fish inlet 5537 facing inwards from the secondary net 5534. The escape-prevention channel 5538 is funnel-shaped, narrower at the inside and wider at the outside.

[0023] The edge-sealing anti-escape fishing net 5533 has a ring structure. Its open end is sewn to the No. 1 fish inlet 5532, and the other end is an open through structure to allow the bass to enter the first-level net 5531. At the position where the edge-sealing anti-escape fishing net 5533 is sewn to the No. 1 fish inlet 5532, a closing rope b is sewn on. The free end of the closing rope b passes through the No. 1 fish inlet 5532 and extends to the embankment 1. When the fishing is over and the net needs to be lifted, the operators on the shore pull the closing rope b to tighten the entrance and completely seal the net to prevent the fish from escaping. The end of the edge-sealing anti-escape fishing net 5533 away from the No. 1 fish inlet 5532 has a silicone sand ball 5533b sewn on its upper part (to provide downward gravity) and a float 5533a sewn on its lower part (to provide upward buoyancy). The silicone sand ball 5533b and the float 5533a are symmetrically distributed, and the torque balance is used to make the inlet open naturally and vertically in the water, avoiding the distortion of the net opening.

[0024] The rolled edge 5535 is sewn onto the top netting, bottom netting, and side netting of the secondary netting 5534. The rolled edge 5535 has a flexible tube structure and a weight a inside, so that the secondary netting 5534 hangs naturally and the net shape is stable.

[0025] The mesh size of the primary net (5531) is larger than that of the secondary net (5534). Through this tiered netting system, during operation, the bass are induced to enter the primary net (5531) through the first inlet (5532). Smaller bass can pass through the larger mesh of the primary net (5531) and enter the secondary net (5534) through the escape-prevention channel (5538), where they cannot swim back out. Larger bass, however, are trapped within the primary net (5531). This allows for simultaneous harvesting and grading.

[0026] The silicone skirt 555 is made of flexible and wear-resistant material. When the fishing net 55 is placed in the aquaculture pond 2, the silicone skirt 555 flexibly fits the bottom of the aquaculture pond 2. The silicone skirt 555 is arranged in a segmented structure and is flexibly connected. The adjacent segments of the silicone skirt 555 are connected by flexible hinges or highly elastic materials.

[0027] When the net sinks to the bottom of pond 2, the segmented silicone skirt 555 can flexibly adapt to the uneven terrain of the pond bottom (such as silt pits, rocks, etc.) like a multi-legged animal, achieving a flexible and tight fit with the pond bottom. This not only effectively seals the bottom gaps and prevents the bass from escaping from the bottom of the net, but also avoids damage to the fish scales or the anti-seepage membrane of the pond bottom due to the flexibility and wear resistance of the silicone material.

[0028] In the above structure, the drive component 4 can be selected according to the actual situation; in the above structure, a 0-90° angle adjustment seat is provided at the connection between the rotating seat 53 and the support seat 52, which can adopt a worm gear locking structure or a ratchet positioning structure. This rotating adjustment seat is existing technology, so the internal details are not shown in the attached drawings, allowing the operator to adjust the support structure to a specific tilt angle according to the operational requirements; in the above structure, the number of buoys 56 can be increased or decreased according to the actual application. The buoys 56 are installed with hooks in conjunction with the fishing net 55 and the support plate 54; in the above structure, the support seat 52 can be set as an electric telescopic rod that moves upward; in the above structure, the rolled edge 5535 can be a PVC pipe, and the sinker a can be lead pellets or iron chains, which can be selected according to the actual situation. Example 2

[0029] Based on Example 1, the dynamic response capability of the net was further optimized, and an intelligent light-attracting structure based on the visual physiological characteristics of bass was introduced, referencing... Figure 7 The surface of the secondary net 5534 is uniformly stitched with magnetic shaping frames 5536. The shaping frames 5536 are magnetic structures, and adjacent shaping frames 5536 are attracted by opposite magnetic poles. When the secondary net 5534 is stationary, it is in a contracted state due to the magnetic attraction between two adjacent shaping frames 5536. When the fishing device 5 moves, the magnetic attraction force is overcome by the impact of the water flow, and the secondary net 5534 automatically unfolds to form the maximum fishing space.

[0030] Meanwhile, the secondary mesh 5534 is also equipped with a flexible LED light-attracting light strip, which is configured to emit a blue-green spectrum with a wavelength between 480nm and 520nm; The light-attracting light strip has a constant light mode and a pulse flashing mode. The frequency of the pulse flashing mode is adjustable between 0.5Hz and 2Hz, which is used to simulate biological movement to induce the predatory instinct of bass. The light intensity of the light-inducing light strip can be steplessly adjusted between 300 lux and 1500 lux, and is configured to be linked with the state of the shaping frame 5536: when the secondary mesh 5534 is in a retracted state, the light intensity is lower than 50 lux or emits red light; when the secondary mesh 5534 is in an unfolded state, it automatically switches to the pulse flashing mode of the blue-green spectrum.

[0031] The light-guided LED strip in the above structure is controlled by a terminal system located on the embankment. Example 3

[0032] Based on implementation one, and referring to Figure 7 The support plate 54 is detachably equipped with an anti-jumping guard 7, which includes a mounting plate 71 and a retractable arc-shaped protective net 72 connected to the front surface of the mounting plate 71. The mounting plate 71 and the support plate 54 are fitted together and fixedly connected by bolts. The inner side of the arc-shaped protective net 72 is sewn with anti-scratch velvet, which covers the entire fishing net 55 to prevent the bass from jumping out and escaping, as well as from being damaged by collision.

[0033] Bass are prone to jumping when startled. When the fish jump and collide with the protective net, the scratch-resistant fabric provides effective cushioning protection, preventing scales from falling off, head injuries, or spinal damage, thus maximizing the integrity and survival rate of the fish. At the same time, the curved structure effectively blocks the fish from jumping out of the net. Example 4

[0034] Based on Example 1, and referring to Figure 5 The guide structure 6 includes an electric push rod 61, a telescopic rod 62 connected to the vertical end of the electric push rod 61, and a guide rod 63 installed vertically at equal intervals with the telescopic rod 62. The guide rod 63 passes through the collar 552, and the two are fitted together in a sliding fit. The guide rod 63 is a telescopic structure, and its telescopic length is adapted to the width of the aquaculture pond 2, which can be flexibly adjusted according to the size of the aquaculture pond.

[0035] Specifically, in this embodiment, the electric push rod 61 can also be a structure capable of electric extension and retraction, such as a lead screw, with a telescopic rod 62 connected to its vertical end. The height of the telescopic rod 62 can be adjusted by the electric push rod 61, and the extension length of the guide rod 63 can be adjusted manually or automatically to ensure that its total span is precisely matched with the actual width of the aquaculture pond 2.

[0036] The aforementioned electric push rod 61 can be telescopically configured according to the actual application.

[0037] The guide rod 63 passes through the loops 552 on both sides of the fishing net 55, and the two slide with a clearance fit. This ensures that when fishing, the side of the fishing net 55 is always in close contact with the inner wall of the pond, eliminating lateral gaps and completely preventing bass from escaping from the side net.

[0038] In summary, when this device is in operation, as described in the above embodiments: First, adjust the guide rod 63 and the angle of the support frame according to the pond width; after starting, the net retracts under magnetic force, and the light dims (silent); as the device moves, the water flow opens the net, and the light simultaneously switches to blue-green pulse light (attracting), and the bass enter and are graded; after reaching the endpoint and stopping, the net magnetically attracts and wraps the fish, the closing rope is tightened, and the fish are lifted for unloading. The entire process achieves efficient, low-loss, and automated graded fishing.

[0039] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
