TECHNICAL FIELD

[0001] The present application relates to the technical field of livestock breeding, in particular to a wetland ecological reef structure for promoting the proliferation of benthic organisms. BACKGROUND

[0002] Benthic organisms refer to a group of organisms living on the bottom of a water body, including shellfish, snails, benthic crustaceans, annelids and benthic fish, etc. Such organisms are not only an important part of the aquatic ecosystem, but also the core economic species in artificial breeding. Their growth, development, reproduction and survival state are highly dependent on stable water environment and suitable habitat. As a key structure for simulating natural water bottom ecology, reef is a core supporting facility for benthic organism breeding. In artificial breeding, such as artificial wetland ponds, shallow sea breeding areas, inland pond breeding bases, etc., in order to improve breeding efficiency and yield, artificial reefs are generally used to replace natural water bottom environment to realize the intensive breeding of benthic organisms. Although the water level of such breeding places is generally controllable and moderate in depth, the water level fluctuation is difficult to avoid due to the influence of natural environment and human operation. For example, rainfall weather will cause the water level to rise for a short time, evaporation or water exchange operation will cause the water level to drop, and the coastal breeding area will also be affected by the tide and appear periodic water level changes. When the water level rises, the reef is in a long-term high-pressure and low-oxygen environment at the bottom, and some benthic organisms that rely on the reef are prone to have phenomena such as decreased activity, reduced feeding, and slow growth, and even mass death due to oxygen deficiency in severe cases. When the water level drops, the reef is exposed or in shallow water, and the organisms are easily affected by external environmental stimuli such as sudden temperature change and ultraviolet radiation, and the lack of feed in shallow water will lead to a decrease in survival rate and a decline in quality of the organisms. In view of this, a wetland ecological reef structure for promoting the proliferation of benthic organisms is proposed. SUMMARY

[0003] In view of the above shortcomings of the prior art, the present application provides a wetland ecological reef structure for promoting the proliferation of benthic organisms, which can effectively solve the problem that the water level fluctuation caused by the influence of natural environment and human operation in the artificial breeding of the prior art will lead to problems such as high pressure and low oxygen, exposure and sun exposure, sudden temperature change or lack of feed in the environment of the fixed reef, thereby affecting the survival and growth of benthic organisms.

[0004] To achieve the above purpose, the present application is realized by the following technical scheme: The present application provides a wetland ecological reef structure for promoting the proliferation of benthic organisms, comprising a main unit, comprising a reef body, comprising, a support unit comprising a water platform arranged above the reef body and a support assembly arranged below the water platform for supporting and fixing the water platform; The lifting unit includes a control box mounted on a platform above the water, a fixing mechanism mounted on the control box for fixing the reef body, a lifting mechanism mounted on the control box for adjusting the height of the reef body in conjunction with the fixing mechanism, and a traction mechanism mounted on the control box. The traction mechanism is used to drive the lifting mechanism to move axially while the lifting mechanism is adjusting the height of the reef body. The main unit also includes a flow guiding component installed on the reef body, which is used to reduce water flow resistance during the height adjustment of the reef body.

[0005] Furthermore, the fixing mechanism includes a fixing sleeve fixedly connected to the top of the reef body, a hook sleeved on the inner wall of the fixing sleeve, and a wire rope fixedly connected to the top of the hook for connection with the lifting mechanism.

[0006] Furthermore, the lifting mechanism includes a fixed shaft fixedly connected to the inner wall of the control box, and a traction wheel for pulling the wire rope is rotatably connected to the surface of the fixed shaft.

[0007] Furthermore, the lifting mechanism also includes a fixed frame located inside the control box for connection with the traction mechanism. Two sets of winding rollers are rotatably connected to the inner wall of the fixed frame, and the ends of the wire ropes away from the hooks are fixedly connected to the surfaces of the two sets of winding rollers.

[0008] Furthermore, each of the two sets of take-up rollers is fixedly connected to a gear at one end, the two sets of gears mesh with each other on their radial sides that are close to each other, and the two sets of gears are rotatably connected to the inner wall of the fixed frame on the side away from the axial direction of the take-up rollers.

[0009] Furthermore, a motor is provided on the side of the two sets of gears away from the take-up roller. One side of the motor is fixedly connected to one side of the fixed frame, and the motor is fixedly connected to the axial side of any one of the two sets of gears through the output shaft.

[0010] Furthermore, the traction mechanism includes a traction frame fixedly connected to the inner wall of the control box, a guide groove is provided on the top of the traction frame, a slider is slidably connected to the inner wall of the guide groove, and the top of the slider is fixedly connected to the bottom of the fixed frame.

[0011] Furthermore, a lead screw is rotatably connected to the inner wall of the traction frame, one end of the lead screw rotates through the traction frame, and a threaded sleeve is threadedly connected to the surface of the lead screw, with the top of the threaded sleeve fixedly connected to the bottom of the fixed frame.

[0012] Furthermore, a second motor is fixedly connected to one side of the traction frame, and the second motor is fixedly connected to the end of the lead screw passing through the traction frame via an output shaft.

[0013] Furthermore, the flow guiding component includes conical holes at both the top and bottom of the reef body, with a flow guiding wing plate disposed between the two sets of conical holes, and both sides of the flow guiding wing plate being fixedly connected to the inner wall of the reef body.

[0014] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention, by setting up a height-adjustable reef structure and dynamically adjusting the depth of the reef in accordance with water level changes, effectively adapts to water level fluctuations caused by factors such as rainfall, evaporation, and water exchange in artificial aquaculture sites. It avoids the inability of fixed reefs to adjust their position according to environmental changes, and achieves an adaptive match between key environmental parameters such as water pressure and oxygen content and the survival needs of benthic organisms, ensuring that the organisms are always in the optimal growth environment, and can effectively improve the survival rate and growth efficiency of the organisms. The self-locking characteristic of the motor reduction structure enables the reef to be stably locked at any height, avoiding accidental raising or lowering due to factors such as water flow impact and its own weight. Furthermore, the flow guiding component optimizes the hydrodynamic performance of the reef, guiding the water flow smoothly during the raising and lowering process, significantly reducing water flow resistance, and preventing organisms from falling off due to violent shaking. This ensures the stability and safety of organisms during the raising and lowering process. At the same time, the suspended installation structure allows the reef to produce moderate shaking in a stable state, accelerating the water circulation around the reef and the water renewal inside the pores, improving dissolved oxygen supply, optimizing food distribution, inhibiting the attachment of harmful organisms, and further promoting the metabolism and growth of benthic organisms.

In the state of height adjustment, the lifting mechanism 303 is driven to move axially. The main unit 100 also includes a flow guide component 102 set on the reef body 101. The flow guide component 102 is used to reduce water flow resistance during the height adjustment of the reef body 101. The reef body 101 is made of bio-friendly composite concrete and has a rectangular structure. It has multiple channels reserved inside for benthic organisms to attach and inhabit. The support unit 200 serves as the installation foundation of the overall structure. The water platform 201 is made of stainless steel frame and anti-corrosion wood board splicing. The support component 202 uses multiple sets of stainless steel round pipes. The length of each pipe is determined according to the actual water depth. The bottom is fixed to the bottom of the water by concrete anchor base. The top is fixed to the four corners of the water platform 201 by welding to ensure the levelness and stability of the water platform 201. Specifically, refer to Figures 2 to 4 The fixing mechanism 302 includes a fixing sleeve 3023 fixedly connected to the top of the reef body 101. A hook 3022 is sleeved on the inner wall of the fixing sleeve 3023. A steel wire rope 3021 for connecting to the lifting mechanism 303 is fixedly connected to the top of the hook 3022. The lifting mechanism 303 includes a fixing shaft 3031 fixedly connected to the inner wall of the control box 301. A traction wheel 3032 for pulling the steel wire rope 3021 is rotatably connected to the surface of the fixing shaft 3031. An installation hole is reserved at the center of the top of the reef body 101. The fixing sleeve 3023 is a cylindrical sleeve made of stainless steel. The bottom is fixedly connected to the mounting hole at the top of the reef body 101 by welding. The weld is treated with anti-corrosion coating to prevent underwater corrosion. The hook 3022 is forged from high-strength alloy steel. The lower part is adapted to fit into the inner wall of the fixing sleeve 3023. The hook 3022 and the fixing sleeve 3023 are positioned by a locking pin to ensure reliable connection and prevent falling off. The top of the hook 3022 is fixedly connected to the wire rope 3021 by a wire rope clamp. The wire rope 3021 is made of galvanized anti-corrosion wire rope 3021 to ensure that it can bear the weight of the reef body 101. It should be noted that the fixed shaft 3031 is made of stainless steel and is fixed to the side wall inside the control box 301 by bolts at both ends. The axis of the fixed shaft 3031 is set horizontally. The traction wheel 3032 is a pulley structure with a groove width that matches the diameter of the wire rope 3021. The traction wheel 3032 is rotatably connected to the surface of the fixed shaft 3031 through bearings, ensuring that the traction wheel 3032 rotates flexibly and with low friction. The wire rope 3021 passes around the groove of the traction wheel 3032 to realize the transmission of force and the conversion of direction, guiding the wire rope 3021 to be smoothly connected to the take-up roller 3035. Specifically, refer to Figure 4 and Figure 5The lifting mechanism 303 also includes a fixed frame 3033 disposed inside the control box 301 for connection with the traction mechanism 304. Two sets of take-up rollers 3035 are rotatably connected to the inner wall of the fixed frame 3033. The ends of wire ropes 3021 away from hooks 3022 are fixedly connected to the surfaces of both sets of take-up rollers 3035. Gears 3036 are fixedly connected to one end of each set of take-up rollers 3035. The radially proximal sides of the two sets of gears 3036 are meshed with each other. The axial side of the two sets of gears 3036 away from the take-up rollers 3035 is rotatably connected to the inner wall of the fixed frame 3033. A motor 3034 is disposed on the side of the two sets of gears 3036 away from the take-up rollers 3035. One side of the motor 3034 is fixedly connected to one side of the fixed frame 3033. The motor 3034 is fixedly connected to any one set of gears 3036 via an output shaft. On the axial side of 036; the fixing frame 3033 is a welded stainless steel frame structure. The inner wall of the fixing frame 3033 is reserved with bearing mounting holes for mounting the take-up roller 3035. Both sets of take-up rollers 3035 are made of stainless steel and are rotatably connected to the inner wall of the fixing frame 3033 through bearings. The two sets of take-up rollers 3035 are arranged in parallel. The end of the wire rope 3021 away from the hook 3022 is fixed to the surface of the take-up roller 3035 through the wire rope 3021 fixing clamp. During the winding process, the wire rope 3021 is ensured to be neatly arranged to avoid jamming caused by overlapping winding. Gears 3036 are fixedly connected to the same end of both sets of take-up rollers 3035. The gears 3036 are spur gears 3036, made of alloy structural steel, and are heat-treated to enhance wear resistance. The radial sides of the two sets of gears 3036 that are close to each other mesh with each other. It should be noted that the first motor 3034 is a stepper motor with an IP68 waterproof rating. It is fixedly installed on the side of the fixed frame 3033 through the motor bracket. The output shaft of the first motor 3034 is fixedly connected to the axial side of either of the two sets of gears 3036 through a coupling. During operation, the first motor 3034 drives the connected gear 3036 to rotate. Through the meshing transmission of the gears 3036, the other set of gears 3036 is driven to rotate in the opposite direction, thereby realizing the synchronous reverse rotation of the two sets of winding rollers 3035, completing the winding or unwinding of the wire rope 3021, and finally driving the reef body 101 to achieve the rising or falling action. Specifically, refer to Figure 4 and Figure 6The traction mechanism 304 includes a traction frame 3041 fixedly connected to the inner wall of the control box 301. A guide groove 3045 is provided on the top of the traction frame 3041. A slider 3046 is slidably connected to the inner wall of the guide groove 3045. The top of the slider 3046 is fixedly connected to the bottom of the fixed frame 3033. A lead screw 3043 is rotatably connected to the inner wall of the traction frame 3041. One end of the lead screw 3043 rotates through the traction frame 3041. A threaded sleeve 3044 is threaded onto the surface of the lead screw 3043. The top of the threaded sleeve 3044 is fixedly connected to the bottom of the fixed frame 3033. A second motor 3042 is fixedly connected to one side of the traction frame 3041. The second motor 3042 is fixedly connected to the lead screw 3041 via an output shaft. Rod 3043 passes through one end of traction frame 3041; traction frame 3041 is a stainless steel welded frame, which is fixedly installed on the inner bottom wall of control box 301 by bolts; the top of slider 3046 is fixedly connected to the bottom of fixed frame 3033 of lifting mechanism 303 by bolts; the surface of screw 3043 is heat treated and coated with anti-rust coating; screw 3043 is rotatably connected to the inner wall of traction frame 3041 by bearing; the bearing is a double thrust ball bearing, which can withstand axial force; the internal thread of threaded sleeve 3044 is precisely matched with the thread of screw 3043; the top of threaded sleeve 3044 is fixedly connected to the bottom of fixed frame 3033 of lifting mechanism 303 by bolts. It should be noted that motor 3042 is a servo motor with an IP68 waterproof rating. It is fixedly installed on one side of the traction frame 3041 by a motor bracket. The output shaft of motor 3042 is fixedly connected to one end of lead screw 3043 through the traction frame 3041 via a coupling. During operation, motor 3042 drives lead screw 3043 to rotate. Through the thread transmission between lead screw 3043 and threaded sleeve 3044, the rotational motion of motor 3042 is converted into the horizontal linear motion of threaded sleeve 3044, which in turn drives fixed frame 3033 and lifting mechanism 303 installed on it to move axially along the length direction of guide groove 3045. Specifically, refer to Figure 2 and Figure 3The flow guiding component 102 includes conical holes 1021 at both the top and bottom of the reef body 101. A flow guiding wing plate 1022 is disposed between the two sets of conical holes 1021. Both sides of the flow guiding wing plate 1022 are fixedly connected to the inner wall of the reef body 101. Conical holes 1021 are provided at both the top and bottom of the reef body 101. The larger end of the top conical hole 1021 faces upward and the smaller end faces downward, while the larger end of the bottom conical hole 1021 faces downward and the smaller end faces upward. The top and bottom conical holes 1021 are symmetrically arranged along the axis of the reef body 101. The flow guiding wing plate 1022 is an arc-shaped plate made of stainless steel. The flow guiding wing plate 1022 is disposed at the two sets of conical holes corresponding to the top and bottom. Between 1021, the two sides of the guide vane 1022 are fixedly connected to the inner wall of the reef body 101 by welding. The weld is polished smooth to avoid forming water flow resistance points. When the reef body 101 rises or falls under the drive of the lifting mechanism 303, the water flow will enter through the large end of the top conical hole 1021, be dispersed by the arc-shaped surface of the guide vane 1022 to further reduce water flow resistance, and flow out from the large end of the bottom conical hole 1021 to form a smooth guide channel. This effectively reduces the impact resistance of the water flow on the reef body 101, making the lifting and lowering of the reef body 101 more stable, and at the same time reducing the impact of water flow disturbance on the organisms attached to the surface of the reef body 101.

[0021] The working principle of this invention: In artificial aquaculture sites, such as artificial wetland aquaculture ponds and shallow sea aquaculture areas, although the water level is not high overall, it is often affected by environmental factors such as rainfall, water exchange, evaporation, and tides, which leads to differences in pressure and oxygen content at different depths of the water. When the water level of the aquaculture site rises, the water depth increases, the pressure at the bottom increases, and the vertical stratification of the water intensifies. The oxygen content at the bottom is prone to decrease, especially in summer when the temperature is high or the aquaculture density is high, the decomposition of organic matter at the bottom consumes oxygen faster. At this time, if the reef body 101 remains at its original depth for a long time, the attached benthic organisms, such as shellfish, snails, and benthic crustaceans, will experience a decline in vitality, slow growth, or even death due to excessive pressure and insufficient oxygen. At this time, the reef body 101 can be driven to rise by the lifting unit 300, which can move the reef body 101 to a water layer with moderate pressure and more oxygen content to meet the needs of biological respiration and metabolism. When the water level in the aquaculture site drops, the suitable living area in the upper layer of the original water body moves down with the water level. If the reef body 101 maintains its original height, it may be partially exposed to the air or located in a shallow water area, causing the organisms to be exposed to the sun and dehydrated. In addition, the water temperature in the shallow water area fluctuates greatly and the feed particles are easily lost. At this time, the reef body 101 is driven to descend by the lifting unit 300, so that it moves down to a suitable depth in sync with the water level, ensuring that the organisms are always in a stable water environment that is completely submerged, while adapting to the pressure and oxygen content conditions of the shallow water area. The motor 3034 serves as the power source and is equipped with a worm gear reduction mechanism, which reduces the output speed and increases the torque to meet the power requirements for the smooth lifting and lowering of the reef body 101. Furthermore, through the self-locking characteristics of the reduction mechanism, the worm gear reduction structure enables the reef body 101 to be locked at any height. After the motor 3034 starts, it drives the gear 3036 connected to it to rotate through the output shaft. Since the two sets of gears 3036 mesh with each other, they drive the other set of gears 3036 to rotate synchronously in the opposite direction. The two sets of gears 3036 drive the corresponding take-up rollers 3035 to rotate synchronously in the opposite direction. When the take-up rollers 3035 rotate in the forward direction, they wind the wire rope 3021 onto the surface of the roller. After the wire rope 3021 changes the direction of force through the traction wheel 3032, it pulls the hook 3022 and the fixed sleeve 3023, and finally drives the reef body 101 to rise. Conversely, when the take-up rollers 3035 rotate in the reverse direction, the wire rope 3021 is slowly released, and the reef body 101 descends smoothly under its own gravity. Once the reef body 101 is adjusted to the target height, the motor 3034 stops working, and the equipped reduction mechanism immediately activates the self-locking function to prevent the winding roller 3035 from rotating in the opposite direction, thereby preventing the wire rope 3021 from loosening and ensuring that the reef body 101 remains stably at the set height, and will not rise or fall unexpectedly due to water flow impact, its own weight, or other factors. The support component 202 of the support unit 200 is fixed to the bottom of the water by a concrete anchor base, providing stable support for the water platform 201 and indirectly ensuring the overall stability of the lifting unit 300 and the reef body 101. Furthermore, during lifting or lowering, motor 3042 can be started simultaneously to drive screw 3043 to rotate. Through the threaded transmission between threaded sleeve 3044 and screw 3043, the rotational motion is converted into horizontal linear motion of fixed frame 3033. The slider 3046 at the bottom of fixed frame 3033 slides along guide groove 3045 of traction frame 3041 to adjust the position of winding roller 3035, preventing wire rope 3021 from tangling or misaligning, which would affect the stability of reef body 101 during lifting or lowering. Furthermore, during the raising and lowering of the reef body 101, the water flow enters through the conical hole 1021 at the top of the reef body 101 with the large end facing upwards. After being guided and dispersed by the arc-shaped guide wing plate 1022, it flows out from the conical hole 1021 at the bottom with the large end facing downwards, forming a smooth guide channel. This effectively reduces the impact resistance of the water flow on the reef body 101, avoids the reef body 101 shaking violently during the raising and lowering process, which could cause attached organisms to fall off, and ensures that the raising and lowering action is stable and controllable. Meanwhile, when the reef body 101 is suspended by the steel wire rope 3021 and its height is stabilized, it will also sway slightly due to the impact of the water flow. This slight swaying will cause the water around the reef body 101 to form a local circulation, which will accelerate the water renewal between the surface and the internal pores of the reef, bring the surface water with high oxygen content into the pores of the reef, and at the same time discharge the waste products such as carbon dioxide and ammonia nitrogen produced by biological metabolism in the pores, providing sufficient oxygen supply for organisms and promoting metabolism and growth.
