Description

Technical Field

[0001] This utility model relates to the field of sturgeon farming cage technology, and in particular to a height-adjustable sturgeon farming cage. Background Technology

[0002] Cage aquaculture is a highly intensive aquaculture method that applies pond intensive culture technology to a large body of water with superior environmental conditions to achieve high yields. It can make full use of water and food organisms. Sturgeon is a fish with relatively demanding living environment requirements. Its growth is affected by a variety of factors such as water temperature, water quality, and water flow. In traditional sturgeon farming, cages are mostly used for cultivation.

[0003] In existing sturgeon farming cages, most cages are placed directly in the water, and the bottom of the cage cannot be raised or lowered. This makes it difficult to operate the cages when harvesting sturgeon or cleaning them, increasing labor intensity and costs. Therefore, a height-adjustable sturgeon farming cage is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a liftable sturgeon farming net cage. By setting up a dual-head servo motor, a rotating shaft, a winding reel, and a steel wire rope, two mounting plates can be driven upwards. The two mounting plates will drive the lower frame upwards, thereby causing the sturgeon inside the net cage to float upwards under the influence of the lower frame. This further facilitates the retrieval of the sturgeon inside the net cage. After retrieval, it is also convenient to clean the inside of the net cage, providing advantages such as easy sturgeon retrieval.

[0006] (II) Technical Solution

[0007] This utility model provides a liftable sturgeon farming net cage, including an upper frame and a lower frame below the upper frame. Netting is provided between the upper frame and the lower frame, as well as inside the lower frame. A lifting mechanism is provided at the top of the upper frame.

[0008] The lifting mechanism includes two L-shaped rods fixedly installed on the back of the upper frame. A top plate is fixedly installed on the top of the two L-shaped rods. A dual-head servo motor is fixedly installed on the top of the top plate. Support plates are fixedly installed on both sides of the top of the top plate. A rotating shaft is connected to each of the two output shafts of the dual-head servo motor via a coupling. The opposite ends of the two rotating shafts are rotatably connected to the opposite sides of the two support plates. A winding reel is fixedly installed on the outer side of each of the two rotating shafts. Two sets of guide components are provided on the top of the upper frame. Mounting plates are fixedly installed on the left and right sides of the lower frame. Steel wire ropes are wound on the outer side of each of the two winding reels. The two steel wire ropes are respectively connected to the top of the two mounting plates via the two sets of guide components.

[0009] Preferably, both sets of guide components include an L-shaped plate, two ear plates, and two guide rollers. The two L-shaped plates are fixedly installed on the top of the upper frame and are symmetrically distributed. The two ear plates are fixedly installed on the inner top wall of the L-shaped plate. The two guide rollers are rotatably connected between opposite sides of the two ear plates on the same side. The wire rope is located between the two guide rollers on the same side.

[0010] Preferably, the outer side of the upper frame is provided with multiple sets of buoyancy mechanisms, which are evenly distributed, and the bottom four corners of the lower frame are provided with counterweight mechanisms.

[0011] Preferably, the buoyancy mechanism includes a mounting ring fixedly installed on the outside of the upper frame, and a floating bucket is detachably connected inside the mounting ring.

[0012] Preferably, the counterweight mechanism includes a connecting rope fixedly installed at the bottom of the lower frame, and a counterweight block is detachably connected to the bottom of the connecting rope.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] This liftable sturgeon farming cage uses a dual-head servo motor, a rotating shaft, a winding reel, and steel wire rope to drive two mounting plates upwards. These mounting plates then drive the lower frame upwards, causing the sturgeon inside the cage to float upwards. This makes it easier to retrieve the sturgeon from the cage and also facilitates cleaning the inside of the cage after retrieval. Attached Figure Description

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4 As shown, the present invention proposes a liftable sturgeon farming net cage, which includes an upper frame 1, a lower frame 2 below the upper frame 1, a net 3 between the upper frame 1 and the lower frame 2 and inside the lower frame 2, and a lifting mechanism 4 at the top of the upper frame 1.

[0024] In this invention, a net cage is formed by an upper frame 1, a lower frame 2, and a net 3. Sturgeon can be raised inside the net cage. The lower frame 2 can be moved upward by a lifting mechanism 4. The net 3 is made of a flexible material with appropriately sized mesh openings, which ensures that the sturgeon can move normally inside the net cage while preventing them from escaping, and allows for free water exchange. As the lower frame 2 moves upward, the net 3 bends and folds without affecting the movement of the lower frame 2. The upward movement of the lower frame 2 allows the sturgeon inside the net cage to swim upward with it, making it easy to catch the sturgeon inside the net cage. After the catch is completed, it is also easy to clean the net cage.

[0025] In an optional embodiment, the lifting mechanism 4 includes two L-shaped rods 41 fixedly installed on the back of the upper frame 1. A top plate 42 is fixedly installed on the top of the two L-shaped rods 41. A dual-head servo motor 43 is fixedly installed on the top of the top plate 42. Support plates 44 are fixedly installed on both sides of the top of the top plate 42. A rotating shaft 45 is connected to the two output shafts of the dual-head servo motor 43 through a coupling. The opposite ends of the two rotating shafts 45 are rotatably connected to the opposite sides of the two support plates 44 respectively. A winding reel 46 is fixedly installed on the outer side of the two rotating shafts 45. Two sets of guide components 47 are provided on the top of the upper frame 1. Mounting plates 48 are fixedly installed on the left and right sides of the lower frame 2. Steel wire ropes 49 are wound on the outer side of the two winding reels 46 respectively. The two steel wire ropes 49 are connected to the top of the two mounting plates 48 through the two sets of guide components 47 respectively.

[0026] It should be noted that when the dual-head servo motor 43 is started, the two output shafts of the dual-head servo motor 43 will drive the two rotating shafts 45 to rotate, the two rotating shafts 45 will drive the two winding reels 46 to rotate, and the two winding reels 46 will drive the two wire ropes 49 to wind up, so that the two wire ropes 49 can pull the two mounting plates 48 respectively, thereby causing the two mounting plates 48 to move upward. The two mounting plates 48 will drive the lower frame 2 to move upward, thereby causing the sturgeon inside the net cage to float upward, making it easier to catch the sturgeon. When the two wire ropes 49 are wound up, the two sets of guide components 47 can guide the two wire ropes 49 respectively, ensuring that the two wire ropes 49 can drive the lower frame 2 to rise and fall in the vertical direction as much as possible.

[0027] In an optional embodiment, both sets of guide components 47 include an L-shaped plate 471, two ear plates 472, and two guide rollers 473. The two L-shaped plates 471 are fixedly installed on the top of the upper frame 1 and are symmetrically distributed. The two ear plates 472 are fixedly installed on the inner top wall of the L-shaped plate 471. The two guide rollers 473 are rotatably connected between the opposite sides of the two ear plates 472 on the same side. The wire rope 49 is located between the two guide rollers 473 on the same side.

[0028] It should be noted that the two guide rollers 473 can be installed through the L-shaped plate 471 and the two ear plates 472. The two guide rollers 473 can guide and support the wire rope 49, ensuring that the wire rope 49 can be stably wound up, and also ensuring that the wire rope 49 is always above the mounting plate 48 when it is wound up. This ensures that the mounting plate 48 can move in the vertical direction as much as possible when the wire rope 49 is wound up, and further ensures that the lower frame 2 can move in the vertical direction as much as possible.

[0029] In an optional embodiment, multiple sets of buoyancy mechanisms 5 are provided on the outer side of the upper frame 1, and the multiple sets of buoyancy mechanisms 5 are evenly distributed. Counterweight mechanisms 6 are provided at the four bottom corners of the lower frame 2.

[0030] It should be noted that multiple buoyancy mechanisms 5 can make the net cage float on the water surface, while the counterweight mechanism 6 can ensure that the net cage is as vertical as possible after being put into the water, and also prevent the net cage from swaying significantly due to the waves.

[0031] In an optional embodiment, the buoyancy mechanism 5 includes a mounting ring 51 fixedly installed on the outside of the upper frame 1, and a float 52 is detachably connected inside the mounting ring 51.

[0032] It should be noted that the float 52 can be installed on the outside of the upper frame 1 by means of the installation ring 51. After the net cage is placed in the water, the upper frame 1 floats on the water surface by means of the buoyancy of the float 52 and the water. Feed can be added into the net cage and sturgeon can be caught through the upper frame 1.

[0033] In an optional embodiment, the counterweight mechanism 6 includes a connecting rope 61 fixedly installed at the bottom of the lower frame 2, and a counterweight block 62 is detachably connected to the bottom of the connecting rope 61.

[0034] It should be noted that the lower frame 2 can be reinforced by connecting rope 61 and counterweight 62. Under the gravity of counterweight 62, the net cage can be kept as vertical as possible in the water.

[0035] In addition, when the sturgeon is caught and the lower frame 2 needs to move downward, the dual-head servo motor 43 is started in reverse, so that the wire rope 49 is unfolded. At this time, the lower frame 2 can move downward stably under the gravity of the counterweight 62.

[0036] In an optional embodiment, a battery and a controller are also provided on the top of the top plate 42. The battery supplies power to the dual-head servo motor 43 and the controller, while the controller can control the dual-head servo motor 43.

[0037] Working principle:

[0038] When using this liftable sturgeon farming net cage, the dual-head servo motor 43 is activated. The two output shafts of the dual-head servo motor 43 drive the two rotating shafts 45 to rotate, which in turn drive the two winding reels 46 to rotate. The two winding reels 46 then drive the two wire ropes 49 to wind up. Under the guidance and support of the two guide rollers 473, the two wire ropes 49 pull the two mounting plates 48 upward. The two mounting plates 48 then drive the lower frame 2 upward, causing the sturgeon inside the net cage to float upward, making it easier to catch the sturgeon. After catching, it also facilitates cleaning the inside of the net cage.

[0039] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
