Description

Technical Field

[0001] This utility model relates to the field of aquaculture purification technology, specifically a purification device for the co-culture of blood clam and laver in eutrophic waters. Background Technology

[0002] Blood clams are bivalve mollusks that inhabit the bottom of water bodies, while laver is a large red algae that grows in the upper layers of water. By cultivating blood clams and laver in the same aquatic environment, and utilizing their different ecological niches and physiological characteristics, a synergistic ecological aquaculture system of blood clams and laver can be constructed, realizing the recycling of nutrients. This aquaculture method can effectively reduce the degree of eutrophication of water bodies, improve water quality, increase aquaculture profits, and reduce aquaculture costs, and therefore has attracted much attention from the market.

[0003] In existing technologies, when conducting co-cultivation of blood clams and laver, a purification device is required to adsorb nitrogen and phosphorus from the water. However, if the water flow is slow or stagnant, the device's adsorption of excessive nitrogen and phosphorus will be ineffective, thus affecting the purification effect. To overcome these shortcomings, existing technology (Chinese patent application number 202322880568.4, application date 2023-10-24) provides a purification device for eutrophication of water bodies, which incorporates a stirring mechanism and is powered by a power source. The rotating parts rotate, which in turn drives the stirring blades to rotate. The stirring blades agitate the water, creating water flow. This improves the efficiency of the biological packing material in the biological packing box in adsorbing nutrients such as nitrogen and phosphorus, thereby enhancing the purification efficiency. However, in actual operation, stirring can easily disturb the excrement of blood clams that has settled at the bottom of the aquaculture pond, leading to accelerated eutrophication of the water body. This is not conducive to reducing excessive nitrogen and phosphorus. Furthermore, existing aquaculture ponds are not suitable for evenly distributing feed, resulting in uneven distribution of blood clams and thus limiting the material cycling efficiency of blood clams and laver.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a blood clam-laden seaweed co-culture purification device for eutrophic waters that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a purification device for the co-cultivation of blood cockles and laver in eutrophic waters, in order to solve the problems mentioned in the background art, which are that stirring can easily disturb the blood cockle excrement that has settled at the bottom of the cultivation pond, leading to accelerated eutrophication of the water body and hindering the reduction of excessive nitrogen, phosphorus and other substances. In addition, existing cultivation ponds are not convenient for evenly distributing feed, resulting in uneven distribution of blood cockles, which limits the material recycling efficiency of blood cockles and laver.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a purification device for the co-cultivation of blood clam and laver in eutrophic waters, comprising a cultivation pond, wherein a biological purification box is fixedly installed inside the cultivation pond via an upper fixed frame, and a stirring mechanism is rotatably arranged on both sides of the biological purification box; a settling mechanism is provided inside the cultivation pond, the settling mechanism including a lower fixed frame fixedly connected to the bottom of the cultivation pond, the lower fixed frame having a cross structure, and the four areas formed by the lower fixed frame and the inner wall of the cultivation pond are all covered with a settling net, and the two ends of the settling net are respectively fixedly connected to a first end plate and a second end plate, the first end plate being snapped into the lower fixed frame. The inner side of the second end plate is fixedly tied to the top of the second end plate with a first pull rope. The end of the first pull rope passes through the lower fixed frame and the upper fixed frame to the outside of both sides of the aquaculture pool. The top of the second end plate is fixedly tied to a second pull rope, and the end of the second pull rope also extends to the outside of both ends of the aquaculture pool. The ends of the first pull rope and the second pull rope are fixedly connected to limit rings. The outer wall of the aquaculture pool is provided with limit components to fix the limit rings. The stirring mechanism is driven to rotate by a dual-shaft motor installed on the upper fixed frame. The top of the aquaculture pool is provided with a feeding mechanism to evenly distribute the feed so that the blood clams are evenly distributed, thereby improving the material recycling efficiency of the blood clams and laver.

[0007] Preferably, guide rods are fixedly connected between the inner walls at both ends of the aquaculture pond, and four sinking fishing nets pass around the corresponding guide rods from the bottom.

[0008] Preferably, the inner walls on both sides of the aquaculture pond are provided with limiting grooves, and the first end plate is limited to slide inside the limiting grooves.

[0009] Preferably, the top of the aquaculture pond is fixedly connected with multiple rings, and the first pull rope and the second pull rope both pass through the inner side of the rings.

[0010] Preferably, the limiting component includes a mounting plate fixedly connected to the outer wall of the aquaculture pond, an insert rod slidably connected to the inner side of the mounting plate, and the end of the insert rod passes through the limiting ring and is inserted into the interior of the aquaculture pond. A spring is fixedly connected between the insert rod and the mounting plate.

[0011] Preferably, the feeding mechanism includes a conveyor rail fixedly mounted on the top of the aquaculture pond by multiple support plates, a feeding hopper fixedly connected to the top output shaft of the dual-axis motor, and a feeding hopper with evenly distributed perforations formed on it. The conveyor rail is inclined downwards and its bottom end is suspended above the feeding hopper.

[0012] Preferably, an n-shaped fixing rod is fixedly connected to the conveying rail, and the bottom end of the fixing rod rotates around the bottom center of the throwing hopper, and multiple sets of evenly arranged loose pieces are formed on the fixing rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This purification device for the co-cultivation of blood clams and laver in eutrophic waters, by setting up a sedimentation component and utilizing the pulling of the rope and the fixing effect of the limiting component on the limiting ring, can stably cover the bottom of the cultivation pond with four sedimentation nets. This effectively prevents the excrement settled at the bottom of the pond from being stirred up by the stirring mechanism, thus preventing the water from accelerating eutrophication. This is beneficial for reducing excessive nitrogen, phosphorus and other substances. At the same time, by setting up a feeding mechanism... The feed can be evenly distributed so that the blood clams are evenly distributed, thereby improving the material recycling efficiency of blood clams and seaweed. The specific contents are as follows: (1) By setting up a settling component, the first pull rope, the second pull rope and the limiting component can fix the limiting ring, so that the four settling fishing nets can be stably wrapped around the bottom of the aquaculture pond. This can effectively prevent the blood clam excrement that has settled at the bottom of the pond from being stirred up by the stirring mechanism, which would accelerate the eutrophication of the water body, thus facilitating the reduction of excessive nitrogen, phosphorus and other substances.

[0014] After the stirring mechanism is used up, the limiting component can release the limiting ring of the first pull rope, and then pull the four second pull ropes outward to lift the corresponding sinking fishing net upward. The limiting component can then fix the limiting ring of the second pull rope, allowing organisms such as blood clams at the bottom of the aquaculture pond to be exposed, so that they can work together with seaweed and other organisms on the surface of the pond to carry out normal ecological cycles.

[0015] By setting a limiting component, and using a spring to push the insert rod through the limiting ring and stably insert it into the aquaculture pond, the limiting ring can be fixed and limited to ensure the pulling effect of the first or second pull rope on the sinking fishing net.

[0016] By setting up the feeding mechanism, feed can be fed into the feeding hopper via the conveyor rail. The dual-shaft motor starts and drives the feeding hopper to rotate, so that the feed is thrown outward through the hole by centrifugal force, thus achieving uniform feeding. In addition, the setting of the fixing rod and loosening plate can stir and break up the coagulated feed, making it easier to throw out through the hole, thereby further improving the uniformity of feed feeding.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: a purification device for the co-culture of blood clams and laver in eutrophic waters, comprising a culture pond 1, a biological purification box 3 fixedly installed inside the culture pond 1 via an upper fixed frame 2, and a stirring mechanism 4 rotatably installed on both sides of the biological purification box 3; a settling mechanism is provided inside the culture pond 1, the settling mechanism including a lower fixed frame 6 fixedly connected to the bottom of the culture pond 1, the lower fixed frame 6 having a cross structure, and the four areas formed by the lower fixed frame 6 and the inner wall of the culture pond 1 are all covered with a settling net 7, and the two ends of the settling net 7 are respectively fixed. The first end plate 8 and the second end plate 9 are connected. The first end plate 8 is snapped into the inner side of the lower fixed frame 6, and a first pull rope 11 is fixedly tied to its top end. The end of the first pull rope 11 passes through the lower fixed frame 6 and the upper fixed frame 2 in sequence to the outside of both sides of the breeding pond 1. A second pull rope 12 is fixedly tied to the top end of the second end plate 9, and the end of the second pull rope 12 also extends to the outside of both ends of the breeding pond 1. Limiting rings 13 are fixedly connected to the ends of both the first pull rope 11 and the second pull rope 12. A limiting component is provided on the outer wall of the breeding pond 1 to correspondingly fix the limiting rings 13.

[0021] By setting up a sedimentation component, when the stirring mechanism 4 stirs the water inside the aquaculture pond 1 to enhance the adsorption and purification effect of the biological purification box 3, the pulling of the first pull rope 11 and the second pull rope 12, along with the fixing effect of the limiting component on the limiting ring 13, allows the four sedimentation nets 7 to be stably wrapped around the bottom of the aquaculture pond 1. This effectively prevents the excrement of organisms such as blood clams that have settled at the bottom of the pond from being stirred up by the stirring mechanism 4, which would accelerate the eutrophication of the water. This is beneficial for reducing excessive nitrogen, phosphorus, and other substances. After the stirring mechanism 4 is used, the limiting component can be released from the limiting ring 13 of the first pull rope 11. Then, the four second pull ropes 12 can be pulled outward to lift the corresponding sedimentation nets 7 upward. The limiting component can then fix the limiting ring 13 of the second pull rope 12, allowing organisms such as blood clams at the bottom of the aquaculture pond 1 to be exposed and work together with seaweed and other organisms on the surface of the pond to carry out normal ecological cycles.

[0022] Specifically, the limiting component includes an installation plate 14 fixedly connected to the outer wall of the aquaculture pond 1. An insertion rod 15 is slidably connected to the inner side of the installation plate 14, and the end of the insertion rod 15 passes through the limiting ring 13 and is inserted into the interior of the aquaculture pond 1. A spring 16 is fixedly connected between the insertion rod 15 and the installation plate 14. By setting the limiting component, the spring 16 pushes the insertion rod 15 to pass through the limiting ring 13 and stably insert it into the aquaculture pond 1, so as to fix and limit the limiting ring 13, thereby ensuring the pulling effect of the first pull rope 11 or the second pull rope 12 on the sinking fishing net 7.

[0023] Furthermore, guide rods 10 are fixedly connected between the inner walls at both ends of the aquaculture pond 1, and four sinking fishing nets 7 pass around the corresponding guide rods 10 from the bottom. With the setting of the guide rods 10, when the second pull rope 12 is pulled to lift the sinking fishing nets 7, the sinking fishing nets 7 can be kept vertically attached to the wall, preventing the sinking fishing nets 7 from being randomly flipped over and causing the excrement at the bottom of the pond to be disturbed and turned up. In addition, limit grooves are opened on both sides of the inner walls of the aquaculture pond 1, and the first end plate 8 is limited to slide inside the limit groove. With the setting of the limit groove, when the first pull rope 11 is pulled to cover the sinking fishing nets 7 again at the bottom of the aquaculture pond 1, the first end plate 8 can be accurately locked into the interior of the lower fixed frame 6.

[0024] In addition, multiple rings are fixedly connected to the top of the breeding pond 1, and the first pull rope 11 and the second pull rope 12 pass through the inner side of the rings to restrict and guide the ropes when they are pulled, which is convenient and saves effort.

[0025] Example 2: Based on Example 1, the stirring mechanism 4 is driven to rotate by the dual-shaft motor 5 installed on the upper fixed frame 2. The top of the breeding pond 1 is equipped with a feeding mechanism to evenly distribute the feed so that the blood clams are evenly distributed, thereby improving the material recycling efficiency of the blood clams and laver.

[0026] Specifically, the feeding mechanism includes a conveyor rail 18 fixedly mounted on the top of the aquaculture pond 1 by multiple support plates 17. The top output shaft of the dual-shaft motor 5 is fixedly connected to a feeding hopper 19, and the feeding hopper 19 has evenly distributed perforations. The conveyor rail 18 is inclined downwards, and its bottom end is suspended above the feeding hopper 19. With the setting of the feeding mechanism, when feeding, the feed can be sprinkled on the conveyor rail 18 at the edge of the aquaculture pond 1. The feed continues to slide down the inclined conveyor rail 18 and falls into the interior of the feeding hopper 19. At the same time, the dual-shaft motor 5 starts and drives the feeding hopper 19 to rotate. The feed inside the feeding hopper 19 is thrown outwards through the perforations due to centrifugal force, thereby achieving uniform feeding.

[0027] Furthermore, an n-shaped fixed rod 20 is fixedly connected to the conveyor rail 18, and the bottom end of the fixed rod 20 rotates to the center of the bottom end of the throwing hopper 19. The fixed rod 20 is formed with multiple sets of evenly arranged loose pieces 21. When the throwing hopper 19 rotates, the fixed rod 20 and loose pieces 21, which are in a stationary state, can stir the feed that is rotating synchronously in the throwing hopper 19 to break up the coagulated feed and make it easier for it to be thrown out of the hole, thereby further improving the uniformity of feed throwing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
