[0001] This utility model belongs to the field of floating bed technology for aquaculture, and specifically relates to a floating bed for algae cultivation. Background Technology
[0002] Currently, there are various forms of aquaculture floating beds, which are usually set up to float naturally or fixed on the water surface. The floating beds can float with the rise and fall of the water level. Ecological floating beds can reduce water pollution through the adsorption and absorption of plant roots. Algae are divided into surface algae and underwater algae, and surface algae and underwater algae have different requirements for the planting environment.
[0003] In the prior art, Chinese patent with publication number CN222786643U discloses an adjustable-depth algae cultivation floating bed. This prior art is set up in paddy fields, and the water flow in the paddy fields can easily cause the prior art to sway or move, which is not convenient for cultivation management. Utility Model Content
[0004] To address the shortcomings of the existing technology, the present invention aims to provide an algae cultivation floating bed. This algae cultivation floating bed is equipped with a structure for fixing the position of the floating plate, which can prevent the floating plate from moving in the paddy field and can adjust the position of the floating plate in the water according to the needs of use, thereby meeting the planting needs of surface algae and underwater algae.
[0005] The technical solution adopted by this type of floating bed for algae cultivation to solve its technical problems is as follows:
[0006] An algae cultivation floating bed is provided, including a floating plate with evenly distributed cultivation troughs on the top surface of the floating plate. The bottom surface of the cultivation troughs is open and a filter screen is fixedly installed. Mounting rings are fixedly installed on the front and rear sides of the floating plate, and a vertical shaft passes through the mounting rings. A mounting plate is fixedly installed at the lower end of the vertical shaft. A pin is fixedly installed on the bottom surface of the mounting plate. An adjustment device for limiting the position of the mounting rings is provided on the vertical shaft.
[0007] Furthermore, the vertical axis has a multi-segment structure, consisting of multiple connecting shafts that are connected by a connecting structure.
[0008] Furthermore, the connection structure includes a threaded post, which is fixedly installed at the lower end of the connecting shaft. Both ends of the connecting shaft are provided with threaded holes, which are threadedly engaged with the threaded post.
[0009] Furthermore, sealing rings are fixedly installed on the lower end face of the connecting shaft.
[0010] Furthermore, the adjustment device includes an adjustment screw and a movable tube. The upper end of the movable tube is sealed. The upper end of the adjustment screw is fixedly connected to the top surface of the inner wall of the movable tube. The inner wall of the movable tube slides in fit with the outer wall of the vertical shaft. The upper end face of the vertical shaft has a threaded hole that is threaded in fit with the adjustment screw.
[0011] Furthermore, a washer is fixedly installed at the lower end of the movable tube.
[0012] Furthermore, the outer periphery of the movable tube is fixedly fitted with anti-slip texture.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model illustrates a floating bed for algae cultivation. It is used for algae cultivation in paddy fields. First, the user inserts pins into the paddy field to fix the vertical shaft using the mounting plate. Second, the user aligns the mounting ring with the vertical shaft, allowing the shaft to pass through the ring. After releasing the floating plate, it floats under the influence of water, allowing the user to plant algae in the cultivation tank. Third, the user adjusts the position of the mounting ring using an adjustment device, thereby adjusting the depth of the floating plate in the water. This design is suitable for both surface and underwater algae cultivation. In addition to meeting the needs of algae cultivation, users can stack the floating plates to cultivate surface algae in the uppermost trough and underwater algae in the troughs of the other floating plates located below the water surface. The floating plates can be aligned sequentially, which also prevents underwater algae from escaping from the troughs. Compared with the prior art, this utility model has a structure for fixing the position of the floating plates, which can prevent the floating plates from moving in the paddy field. Furthermore, the position of the floating plates in the water can be adjusted according to the needs of use, thereby meeting the cultivation needs of both surface and underwater algae.
[0015] 2. The algae cultivation floating bed of this utility model allows users to adjust and control the height of the vertical axis according to the water depth, making it more convenient to use.
[0016] 3. The algae cultivation floating bed of this utility model can be connected sequentially according to the usage requirements by screwing the threaded post into the threaded hole of the corresponding connecting shaft. The threaded connection has a simple structure, and the threaded post is located in the threaded hole, which prevents water from entering the thread and avoids rusting.
[0017] 4. In the example of this utility model, an algae cultivation floating bed has a sealing ring that can increase the sealing between the connecting shafts and further prevent water from entering the connection of the connecting shafts.
[0018] 5. In an example of this utility model, an algae cultivation floating bed is provided. When the adjusting screw is screwed into the threaded hole, it can drive the movable tube to move up and down. The bottom surface of the movable tube can contact the top surface of the mounting ring, thereby limiting the top surface of the floating plate and controlling the position of the floating plate.
[0019] 6. In the algae cultivation floating bed of this utility model, the pad ring can prevent the lower end of the movable tube from making hard contact with the top surface of the mounting ring, thereby reducing the wear caused by friction.
[0020] 7. In this utility model example, an algae cultivation floating bed has anti-slip textures that increase the friction between the user's hand and the outer periphery of the moving tube, thus preventing slippage. Attached Figure Description
