Description

Technical Field

[0001] This utility model relates to the field of seaweed cultivation technology, and in particular to a seaweed cultivation device. Background Technology

[0002] Seaweed cultivation is the process of artificially controlling environmental conditions, such as light, temperature, and water quality, to promote seaweed growth. Common seaweed cultivation methods include open pond cultivation and closed photobioreactor cultivation. Seaweed not only absorbs carbon dioxide and releases oxygen through photosynthesis, but it can also be used in many fields such as food, cosmetics, and medicine. Seaweed cultivation requires specialized equipment.

[0003] Traditional open pond culture involves cultivating seaweed on a large scale in raceway ponds, which are typically located in sunny areas to maximize the use of natural light. The water temperature and quality in the ponds are mainly controlled by the natural environment, requiring no complex facilities or extensive human intervention, resulting in relatively low operating costs. The seaweed absorbs carbon dioxide and releases oxygen through photosynthesis in the ponds, promoting its growth. Because the area above the raceway pool is completely open, the seaweed is easily disturbed by external factors during cultivation, with pollutant intrusion being particularly serious. Pollutant intrusion can not only lead to water quality deterioration but also affect the growth process of seaweed, inhibit photosynthesis, and even cause seaweed death or reduced yield. Utility Model Content

[0004] Therefore, it is necessary to provide an algae cultivation device to address the problem of algae cultivation in raceway pools being easily invaded by pollutants.

[0005] A seaweed cultivation device includes: a raceway pool and a partition disposed at the center of the bottom wall of the raceway pool, wherein the raceway pool is provided with paddles; The protective mechanism includes a hinged plate disposed above the runway pool, a drive block disposed below the hinged plate, and an air intake assembly disposed on one side of the runway pool.

[0006] In one embodiment, the drive block is slidably connected to the inner wall of the partition, a positioning rod is fixedly connected to the top of the drive block, and the hinge plate is hinged to the positioning rod.

[0007] In one embodiment, the partition is provided with a reciprocating lead screw and a servo motor. The servo motor is fixedly connected to the inner wall of one end of the partition, the drive end of the servo motor is fixedly connected to one end of the reciprocating lead screw, and the other end of the reciprocating lead screw is rotatably connected to the inner wall of the partition.

[0008] In one embodiment, the surface of the reciprocating screw is provided with a moving block, the top of the moving block is semi-circular, and the driving block is a trapezoid with curved sides. The moving block and the driving block are used in conjunction.

[0009] In one embodiment, the air intake assembly includes a housing, which is double-layered, with an air intake pipe and an air pump disposed on the lower layer of the housing, and the air pump being connected to the air intake pipe.

[0010] In one embodiment, the lower end of the outer casing is provided with an opening, and a louver is provided at the opening, the louver being inclined downwards.

[0011] In one embodiment, the end of the air intake pipe away from the air pump is connected to the upper layer of the outer shell, and a plurality of ventilation holes are provided between the upper layer of the outer shell and the runway pool, and the upper layer of the outer shell and the runway pool are connected through the ventilation holes.

[0012] In one embodiment, a controller is provided on the side of the runway pool away from the air intake assembly, and the propeller, servo motor and air pump are all electrically connected to the controller.

[0013] Beneficial effects

[0014] By periodically opening and closing hinged plates and movable blocks above the raceway pool, effective gas exchange can be achieved while avoiding interference from external pollutants. Each time the hinged plates expand, they enhance gas flow within the pool, promoting photosynthesis; when closed, they act as a shield, reducing pollutant intrusion, stabilizing water quality, and improving the stability of the algae growth environment, while also reducing the negative impacts of air pollution. By continuously injecting air into the runway pool through an air pump and air intake pipe, the carbon dioxide required for algae photosynthesis is increased, as well as the gas concentration in the runway pool. When the corresponding hinge plate is opened, air and oxygen rush out from the opening of the hinge plate, thereby reducing the probability of air pollutants entering the runway pool.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This invention describes the seaweed cultivation equipment.

[0020] In one embodiment, an algae cultivation device includes: a raceway pool 100 and a partition 200 disposed at the center of the bottom wall of the raceway pool 100, and a paddle 110 disposed inside the raceway pool 100. The protective mechanism 300 includes a hinge plate 310 disposed above the runway pool 100, a drive block 320 disposed below the hinge plate 310, and an air intake assembly 340 disposed on one side of the runway pool 100.

[0021] The specific operating procedure for this device is as follows: Before using the racetrack pool 100, the inside of the racetrack pool 100 needs to be thoroughly cleaned and disinfected to eliminate potential contaminants. After the pool is cleaned, the prepared culture medium is injected into the interior of the raceway pool 100 to provide the necessary elements for algal growth. Algal inoculation involves introducing highly active algal strains into the culture medium. Driven by blade 110, the water circulation is promoted to achieve uniform cell suspension, and the algal cells are forced to be alternately exposed to the light and dark areas, which optimizes photosynthetic efficiency and avoids light damage, carbon dioxide dissolution and oxygen escape.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, the drive block 320 is slidably connected to the inner wall of the partition 200, and a positioning rod is fixedly connected to the top of the drive block 320. The hinge plate 310 is hinged to the positioning rod. A reciprocating screw 330 and a servo motor 332 are disposed inside the partition 200. The servo motor 332 is fixedly connected to the inner wall of one end of the partition 200, and the drive end of the servo motor 332 is fixedly connected to one end of the reciprocating screw 330. The other end of the reciprocating screw 330 is rotatably connected to the inner wall of the partition 200. A moving block 331 is disposed on the surface of the reciprocating screw 330. The top of the moving block 331 is semi-circular. The drive block 320 is a trapezoid with curved sides. The moving block 331 and the drive block 320 are used in conjunction. The air intake assembly 340 includes a housing 341, which is double-layered. The lower layer of the housing 341 is provided with an air intake pipe 342 and an air pump 343, which is connected to the air intake pipe 342. An opening is provided at one end of the lower layer of the outer casing 341, and a louver 345 is provided at the opening, with the louver 345 tilted downwards. The end of the air inlet pipe 342 away from the air pump 343 is connected to the upper layer of the outer casing 341. Multiple ventilation holes 344 are provided between the upper layer of the outer casing 341 and the runway pool 100, and the upper layer of the outer casing 341 and the runway pool 100 are connected through the ventilation holes 344.

[0023] In this embodiment, the raceway pool 100 is generally elliptical in shape, with a rectangular middle section and semicircular ends. The upper surface and sides of both ends of the raceway pool 100 are provided with glass, and glass is also provided between every two hinge plates 310. The hinge plates 310 are made of stainless steel and are opaque. Therefore, when algae move to the ends of the raceway pool 100, they are exposed to light. When they move to the middle, they alternate between the light and dark areas, thereby optimizing photosynthetic efficiency. The hinge plate 310 consists of two telescopic plates that are hinged to each other under the action of a positioning rod. One end of the telescopic plate is hinged to the two side surfaces of the raceway pool 100, and the other ends of the two telescopic plates are hinged to the positioning rod. When the movable block moves below the drive block 320, the inclined surface of the movable block will push the drive block 320 upward along the inclined surface of the drive block 320. As the drive block 320 moves upward, it will drive the positioning rod upward, thereby pulling the hinge end of the hinge plate 310 upward and unfolding it, forming a triangular area above the runway pool 100 for exchanging gas with the outside. As the movable block continues to move, since the bottom end of the drive block 320 is flat, the corresponding hinge plate 310 will remain open for a period of time. When the movable block moves to the other side, the side of the drive block 320 will slowly slide downward along the top surface of the movable block, thereby causing the hinge plate 310 to slowly close. Then another hinge plate 310 will open, and so on, so that most areas in the runway pool 100 can be directly circulated with air, reducing the probability of excessively high local oxygen concentration. It should be noted that this device reduces the problem of the runway pool 100 being exposed to the outside world and contaminated by pollutants by setting an openable hinged plate 310 at the top of the runway pool 100. This device achieves a balance by reducing the area of ​​the algae receiving light above the runway pool 100 and increasing the area of ​​the runway pool 100 receiving light from the sides. Furthermore, algae need to be cultivated in an environment with alternating light and dark conditions, and the concentration of air entering the runway pool 100 can be adjusted by regulating the power of the air pump 343. Therefore, the protective mechanism 300 of this device will not have a negative impact on the growth and development of algae.

[0024] like Figure 1 and Figure 2 As shown, a controller is provided on the side of the runway pool 100 away from the air intake assembly 340, and the blades 110, servo motor 332 and air pump 343 are all electrically connected to the controller.

[0025] In this embodiment, the controller is located on the side away from the air intake assembly 340. Next to the controller, a drive motor is provided to drive the blade 110. The drive motor increases the output torque to the blade 110 through a reducer. At the same time, the controller can program and control the servo motor 332, the drive motor and the air pump 343.

[0026] Working principle: The algae continuously photosynthesize in the raceway pool 100, while the paddle 110 drives the water in the raceway pool 100 to circulate between the raceway pool 100 and the baffle 200, so that the algae cells continue to flow in the water and prevent them from settling and accumulating at the bottom; then the servo motor 332 and the air pump 343 are started by the controller. The servo motor 332 drives the reciprocating screw 330 to rotate through the coupling, thereby driving the movable block to reciprocate inside the partition 200. When the movable block moves to the bottom of the drive block 320, it will push the drive block 320 to move upward, thereby driving the corresponding hinge plate 310 to unfold. When the hinge plate 310 unfolds, the oxygen inside the runway pool 100 and the air supplied into the runway pool 100 by the air intake component 340 will rush out through the gap between the connecting plate and the runway pool 100, forming an airflow. This allows the gas inside the runway pool 100 to exchange with the outside world while reducing the probability of external pollutants entering the runway pool 100. When the air pump 343 is started, it draws outside air into the lower layer of the outer shell 341 through the inlet and injects the air into the air intake pipe 342. At the same time, the air entering the outer shell 341 is filtered by the louvers 345. The air enters the upper layer of the outer shell 341 through the air intake pipe 342, increasing the air concentration in the upper layer of the outer shell 341. The air is then forced into the interior of the raceway pool 100 through the vent 344 by pressure, providing carbon dioxide for the photosynthesis of algae.

[0027] Note: The reciprocating screw 330 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 330 causes the side of the helical groove to push the slider placed in the helical groove to perform axial reciprocating motion.

[0028] It should be noted that the blade 110, reciprocating screw 330, servo motor 332 and air pump 343 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 332 and air pump 343 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
