Description

Technical Field

[0001] This utility model belongs to the field of ecological aquaculture technology, specifically relating to a wetland ecological aquaculture device. Background Technology

[0002] Wetlands are a unique ecosystem on Earth, possessing characteristics of both land and water, and serving as a special ecological transition zone formed by the interaction of land and water. Wetlands are diverse in type, including marshes, peatlands, mudflats, shallow water areas along rivers and lakes, and artificial wetlands. These wetland ecosystems play a vital role in regulating climate, conserving water resources, purifying water quality, and maintaining biodiversity. Wetland ecological aquaculture is a sustainable aquaculture model that utilizes the natural resources and ecological functions of wetlands. It involves the rational use of wetland water bodies, soil, and biological communities to conduct activities such as aquaculture and the cultivation of aquatic plants. The aim is to achieve a win-win situation of ecological balance and economic benefits through the utilization of wetland resources. This aquaculture model not only produces green and environmentally friendly agricultural products but also promotes the protection and restoration of wetland ecosystems.

[0003] In the field of wetland ecological aquaculture, existing technologies have some shortcomings. Traditional aquaculture devices lack effective adaptability to seasonal changes in wetland water levels. For example, during the dry season, when water levels are low, the devices cannot fully utilize water resources, resulting in limited plant growth. During the flood season, when water levels rise sharply, the soil and plants inside the devices are easily washed away, leading to aquaculture failure. In addition, existing wetland aquaculture devices are relatively simple in structural design and lack effective protection and regulation functions, failing to meet the diverse needs of wetland ecological aquaculture. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a wetland ecological aquaculture device with reasonable structural design and multiple functions. It can effectively adapt to changes in wetland water level, protect aquaculture plants and soil, improve the stability and success rate of wetland ecological aquaculture, and has high practical value.

[0005] The solution adopted by this utility model to solve its technical problem is: a wetland ecological aquaculture device, including an aquaculture net cage and an outer frame assembly. The aquaculture net cage is a rectangular structure, and support guide columns are fixed longitudinally at the four rectangular corners of the aquaculture net cage. The outer frame assembly is longitudinally movably fitted on the outside of the aquaculture net cage. The outer frame assembly includes an upper frame, a lower frame, and a middle water-blocking part. The upper frame and the lower frame are rectangular structures and are symmetrically and movably fitted on the outside of the aquaculture net cage. The middle water-blocking part is connected between the upper frame and the lower frame. A middle water-blocking part is provided on each side of the outer frame assembly to provide a water-blocking effect between the upper frame and the lower frame. A driving mechanism is provided between the aquaculture net cage and the outer frame assembly to drive the upper frame and the lower frame to move relative to each other. The middle water-blocking part can unfold or retract following the movement of the upper frame and the lower frame.

[0006] Furthermore, the driving mechanism includes a waterproof box installed on the outside of the aquaculture net cage. A bidirectional hydraulic cylinder is installed inside the waterproof box. A push seat is symmetrically and horizontally slidably fitted on the outside of the aquaculture net cage. Two symmetrical telescopic rods of the bidirectional hydraulic cylinder pass through the waterproof box, extend horizontally outward, and connect to the push seat on the same side. The push seat is hinged to the inner wall of the upper frame and the lower frame respectively through symmetrically arranged push rods. The push rods are V-shaped and hinged between the upper frame, the lower frame, and the push seat.

[0007] Furthermore, the intermediate water-blocking part includes a torsion shaft rotatably mounted between the upper frame and the lower frame, with a waterproof curtain wound around the torsion shaft. The two ends of the waterproof curtain are respectively connected between the upper frame and the lower frame. After the waterproof curtain is unfolded, it forms a complete water-blocking surface with the upper frame and the lower frame.

[0008] Furthermore, guide sleeves are provided at the four rectangular corners of the upper and lower frames. The upper and lower frames are longitudinally slidably mounted on the support guide post through the guide sleeves, and the two ends of the torsion shaft are rotatably mounted on the guide sleeves on the corresponding sides.

[0009] Furthermore, the top and bottom support surfaces of the support guide column are both higher than the aquaculture cage, and the support guide column supports and lifts the aquaculture cage.

[0010] Furthermore, multiple ground cones are arranged longitudinally at the bottom of the lower frame.

[0011] Furthermore, a water-absorbing support is placed at the bottom of the aquaculture cage, and a grid plate is fixed inside the aquaculture cage near the top.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention effectively addresses the shortcomings of existing wetland aquaculture devices by incorporating an outer frame assembly, a drive mechanism, and a central water-blocking section.

[0014] Firstly, the upper and lower frames of the outer frame assembly can move relative to each other, and in conjunction with the unfolding and retracting of the middle water-blocking part, the aquaculture device can be flexibly adjusted according to changes in wetland water level. During the dry season, the outer frame assembly is located in the middle position, which does not obstruct water from entering the bottom and sides of the aquaculture net cage. During the flood season, the outer frame assembly moves to form a water-blocking space to prevent excessive water from destroying plants and soil.

[0015] Secondly, the drive mechanism adopts a combination of a two-way hydraulic cylinder, a pusher and a push rod, which can precisely control the movement of the upper and lower frames and ensure smooth unfolding and rewinding of the middle water-blocking part;

[0016] Thirdly, the design of the torsion shaft and waterproof curtain in the middle water-blocking section utilizes the torsion and automatic reset function of the torsion shaft to achieve flexible unfolding and retraction of the waterproof curtain, forming an effective water-blocking structure.

[0017] Fourth, the support columns lift up the aquaculture cages, which not only increases the range of movement of the upper and lower frames, but also ensures that there is a gap between the bottom of the aquaculture cages and the wetland soil during the dry season, which is conducive to water intake.

[0018] Fifth, a ground cone is installed at the bottom of the lower frame, which is inserted into the deep strata of the wetland during the flood season to enhance the stability of the aquaculture cage. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution for a wetland ecological aquaculture device: Example

[0025] according to Figure 1 and Figure 2As shown, a wetland ecological aquaculture device includes an aquaculture cage 1 and an outer frame assembly 2. The aquaculture cage 1 is a rectangular mesh structure with an opening at the top, and water permeability at the sides and bottom. Supporting guide posts 3 are longitudinally fixed at the four rectangular corners of the aquaculture cage 1. The outer frame assembly 2 is longitudinally movably fitted onto the outside of the aquaculture cage 1. During the dry season, the outer frame assembly 2 is located in the middle of the aquaculture cage 1, without affecting the water permeability at the bottom and sides of the aquaculture cage 1. Specifically, the outer frame assembly 2 includes an upper frame 21, a lower frame 22, and a middle water-blocking part 23. The upper frame 21 and the lower frame 22 are rectangular structures and are symmetrically and movably fitted onto the aquaculture cage 1. On the outside of the cage 1, guide sleeves 24 are provided at the four rectangular corners of the upper frame 21 and the lower frame 22. The upper frame 21 and the lower frame 22 are longitudinally slidably fitted onto the support guide post 3 through the guide sleeves 24. A middle water-blocking part 23 is connected between the upper frame 21 and the lower frame 22, and a middle water-blocking part 23 is provided on each side of the outer frame group 2 to provide a water-blocking effect between the upper frame 21 and the lower frame 22. A drive mechanism 4 is provided between the aquaculture cage 1 and the outer frame group 2 to drive the upper frame 21 and the lower frame 22 to move relative to each other. The middle water-blocking part 23 can unfold or retract following the movement of the upper frame 21 and the lower frame 22.

[0026] The intermediate water-blocking part 23 includes a torque shaft 231 rotatably mounted between the upper frame 21 and the lower frame 22. Both ends of the torque shaft 231 are rotatably mounted on guide sleeves 24 on corresponding sides. The torque shaft 231 has torsional and automatic reset functions via an internal spring. A waterproof curtain 232 is wound around the torque shaft 231. Both ends of the waterproof curtain 232 are connected between the upper frame 21 and the lower frame 22. When the upper frame 21 and the lower frame 22 move in opposite directions, causing the waterproof curtain 232 to unfold, the waterproof curtain 232 and the upper frame 21 and lower frame 22 on the same side... The frame 22 forms a complete water-blocking surface, and the upper frame 21, lower frame 22 and waterproof curtain 232 on all four sides can be enclosed to form a complete shielding space, covering the aquaculture net cage 1 inside. In this way, when there is a lot of water during the flood season, the aquaculture net cage 1 is surrounded and water will no longer enter directly through the sides. The aquaculture net cage 1 can only enter water through the bottom. Since there is enough water during the flood season, water can be provided for the aquatic plants by relying solely on water entering from the bottom, thereby preventing the plants from being drowned by excessive water during the flood season, and also preventing the planting soil inside the aquaculture net cage 1 from being washed away by the water flow.

[0027] There are two sets of drive mechanisms 4, which are symmetrically arranged on both sides of the aquaculture cage 1. The drive mechanism 4 includes a waterproof box 41 installed on the outer wall of the aquaculture cage 1. A bidirectional hydraulic cylinder 42 is installed inside the waterproof box 41. The two telescopic output rods of the bidirectional hydraulic cylinder 42 can extend and retract synchronously and symmetrically. A horizontal guide groove is opened on the outer wall of the aquaculture cage 1. A push seat 43 is horizontally and symmetrically slidably fitted in the guide groove on the outer side of the aquaculture cage 1. The two telescopic rods of the bidirectional hydraulic cylinder 42 pass through the waterproof box 41 and extend horizontally outward and are connected to the push seat 43 on the same side. The push seat 43 is hinged to the inner wall of the upper frame 21 and the lower frame 22 respectively through symmetrically arranged push rods 44. The two sets of push rods 44 cooperate to form a V-shaped structure, and the two ends of the push rods 44 are respectively hinged between the upper frame 21 / lower frame 22 and the push seat 43. When the bidirectional hydraulic cylinder 42 extends, it pushes the push seat 43 to move outward. The push seat 43 drives the push rod 44 to move. With the cooperation of the push rod 44, the upper frame 21 and the lower frame 22 can be controlled to move in opposite directions.

[0028] The top and bottom support surfaces of the support column 3 are both higher than those of the aquaculture cage 1. When the aquaculture cage 1 is placed in the wetland, the support column 3 can support and lift the aquaculture cage 1. The purpose of this setting is, on the one hand, to increase the range of movement of the upper frame 21 and the lower frame 22, so that the upper frame 21 and the lower frame 22 can move further up or down under the guidance of the support column 3, thereby increasing the area of ​​the outer frame group 2 that covers the aquaculture cage 1. On the other hand, it can lift the aquaculture cage 1 so that when the water is dry, the support column 3 is supported on the soil, and a certain gap is left between the soil of the wetland and the bottom of the aquaculture cage 1, so that water can smoothly enter the aquaculture cage 1 to provide sufficient water for the aquatic plants.

[0029] During wetland aquaculture, a water-absorbing support 6, such as an absorbent sponge, can be placed at the bottom of the aquaculture cage 1. The water-absorbing support 6 serves two purposes: firstly, it supports the planting soil within the aquaculture cage 1 and isolates the soil from the wetland mud, preventing microorganisms and bacteria in the wetland from directly contacting the roots of the aquatic plants and causing rapid root rot; secondly, during the flood season, the water-absorbing support 6 prevents large water flows from washing away the planting soil directly from the bottom of the aquaculture cage 1. Thirdly, the absorbent sponge provides excellent water absorption and conduction between the soil and the wetland water source. A grid plate 5 is fixed near the top inside the aquaculture cage 1. The grid plate 5 assists in supporting the roots and stems of the aquatic plants, allowing them to grow upright.

[0030] In practical use, this utility model of a wetland ecological aquaculture device involves placing an aquaculture cage 1 and the aquatic plants planted within it into the wetland. The aquaculture cage 1 is supported by support guide columns 3. When the wetland is in a dry season, the outer frame assembly 2 is positioned in the middle of the aquaculture cage 1, allowing water to enter through the bottom and sides, providing ample water for plant growth. When the wetland is in a flood season, the water level rises. At this time, the bidirectional hydraulic cylinder 42 can be extended, pushing the push rod 44 through the push seat 43. Under the push of the push rod 44, the upper frame 21 and the lower frame 22 move in opposite directions. After the upper frame 21 moves upward, it is higher than the top of the aquaculture cage 1. 21. The top height of the aquaculture cage 1 is further increased, and the lower frame 22 moves downwards to be lower than the bottom of the aquaculture cage 1, thus enclosing the bottom of the aquaculture cage 1. At the same time, the upper frame 21 and the lower frame 22 can pull the waterproof curtain 232 to unfold during the reverse movement. Through the cooperation of the waterproof curtain 232, the upper frame 21 and the lower frame 22, a complete water-blocking space is formed on the outside of the aquaculture cage 1 to prevent the increased water volume during the flood season from destroying the soil and plants inside the aquaculture cage 1. After the flood season ends, the outer frame group 2 is reset again, and the waterproof curtain 232 is rolled up through the automatic reset function of the torsion shaft 231, and the aquaculture cage 1 returns to normal aquaculture water supply status. Example

[0031] Based on Example 1, the similarities between this example and Example 1 will not be repeated here. The differences are as follows: Figure 1-3 As shown, in order to further improve the stability of the aquaculture cage 1 during the wetland flood season, multiple ground cones 7 are arranged longitudinally at the bottom of the lower frame 22. When the drive mechanism 4 controls the upper frame 21 and the lower frame 22 to move in opposite directions, the lower frame 22 moves downward, and the ground cones 7 at the bottom of the lower frame 22 can be pushed and inserted into the deeper layers of the wetland to reinforce the aquaculture cage 1, thereby improving the stability of the aquaculture cage 1 during the wetland flood season and preventing the aquaculture cage 1 from being washed away by the large water flow during the flood season.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
