Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture floating bed technology, specifically a floating bed for aquatic plant cultivation. Background Technology
[0002] Ecological floating beds are a type of artificial floating island designed for eutrophic water. They utilize ecological engineering principles to reduce the levels of COD, nitrogen, and phosphorus in the water. They are mainly composed of aquatic plants, employing soilless cultivation techniques and using polymer materials as carriers and substrates. By leveraging interspecies symbiotic relationships and making full use of the ecological niches and nutrient niches in the water, they establish highly efficient artificial ecosystems to reduce the pollution load in water bodies.
[0003] Traditional floating beds for aquatic plant cultivation suffer from the following problems during use: most existing floating beds cannot flexibly adjust their suspension depth according to the growth needs of different aquatic plants and changes in the aquatic environment. Different aquatic plants have different requirements for light, temperature, nutrients, and other conditions during their growth, and the environmental conditions vary at different depths of the water. Therefore, a new type of floating bed for aquatic plant cultivation is proposed to address these issues. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a floating bed for aquatic plant cultivation.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The floating bed for aquatic plant cultivation according to this utility model includes a floating bed body, several placement platforms are rotatably installed on the floating bed body, and a cultivation cylinder is set in the placement platform through a clamping assembly. An adjustment assembly is provided on the floating platform body, and the adjustment assembly includes a pair of sliding grooves fixedly installed on the floating platform body. A slide frame is slidably installed in the sliding grooves, and buoyancy plates are fixedly installed at both ends of the slide frame. A dual-axis motor is fixedly installed on the floating bed body, and a threaded rod is fixedly installed on the output shaft of the dual-axis motor located at the top. The threaded rod passes through the slide frame and is threadedly connected to it. When the threaded rod rotates, it drives the buoyancy plates on the slide frame to submerge or leave the water body, thereby changing the buoyancy force on the floating bed body and changing the depth of the floating bed body.
[0006] Furthermore, the adjustment assembly also includes a pair of movable slots on the main body of the floating bed, in which toothed plates are slidably installed. Several toothed grooves that mesh with the toothed plates are provided on the placement platform. One end of a connecting rope is fixedly installed on the slide, and the other end of the connecting rope passes around the crossbar and is fixedly connected to the toothed plates. When the slide and the connecting rope work together to drive the toothed plates to move, the toothed plates can drive the placement platform and the aquaculture tank to rotate, preventing the roots of aquatic plants from growing into the riverbed and keeping the roots suspended in the upper layer of the water, so that they can preferentially contact the eutrophic surface water.
[0007] Furthermore, a boss is fixedly installed on the main body of the floating bed, and a spring is fixedly installed on the boss, with the other end of the spring fixedly connected to the toothed plate.
[0008] Furthermore, a flexible lever is fixedly installed on the lower output shaft of the dual-axis motor, and the flexible lever is located below the aquaculture tank.
[0009] Furthermore, the clamping assembly includes a movable channel formed within the placement platform, a clamping rod slidably mounted within the movable channel, a rubber pad provided on the placement platform, and the upper end of the clamping rod contacting the rubber pad.
[0010] Furthermore, the dual-axis motor is provided with a motor protective shell.
[0011] The advantages of this utility model are:
[0012] 1. The dual-axis motor drives the threaded rod to rotate, which in turn moves the slide and the buoyancy plate up and down. By changing the volume of the buoyancy plate submerged in the water, the suspension depth of the floating bed body is adjusted. When the slide moves, the toothed plate is pulled by the connecting rope. The toothed plate meshes with the tooth groove of the placement platform, which drives the aquaculture cylinder to rotate. The spring maintains the meshing stability. The rotation of the aquaculture cylinder makes the roots evenly distributed and prevents them from sinking into the riverbed.
[0013] 2. The rubber pad and clamping rod of the clamping assembly of this utility model cooperate to use the weight of the breeding tube itself to firmly clamp itself, while also achieving the effect of convenient replacement of the breeding tube. Attached Figure Description

[0021] 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 scope of protection of the present utility model.
[0022] Please see Figure 1-5 As shown, a floating bed for aquatic plant cultivation includes a main body 1. Several placement platforms 2 are rotatably mounted on the main body 1. Aquaculture cylinders 6 are disposed within each placement platform 2 via clamping components 5. An adjusting component 3 is provided on the main body of the floating platform. The adjusting component 3 includes a pair of sliding grooves 302 fixedly mounted on the main body of the floating platform. A sliding frame 303 is slidably mounted within each sliding groove 302. Buoyancy plates 304 are fixedly mounted at both ends of each sliding frame 303. A dual-axis motor 301 is fixedly mounted on the main body 1. A threaded rod 305 is fixedly mounted on the upper output shaft of the dual-axis motor 301. The threaded rod 305 passes through and is threadedly connected to the sliding frame 303. When the threaded rod 305 rotates, it causes the sliding frame 303 to float upwards. The buoyancy plate 304 submerges or leaves the water, changing the buoyancy of the floating bed body 1 and thus altering its depth. After the dual-shaft motor 301 starts, the upper output shaft drives the threaded rod 305 to rotate. The threaded rod 305 is threadedly connected to the slide 303, causing the slide 303 to slide up and down along the slide groove 302. The buoyancy plates 304 at both ends of the slide 303 move with the slide 303. When the buoyancy plate 304 is submerged in the water, the volume of water displaced increases, increasing the buoyancy of the floating bed body 1, causing it to float. Conversely, when the buoyancy plate 304 leaves the water, the buoyancy decreases, and the floating bed body 1 sinks. By adjusting the depth of the floating bed body 1, the aquatic plants in the aquaculture tank 6 can adapt to different water layers and temperature conditions, improving their growth efficiency.
[0023] The adjustment assembly 3 also includes a pair of movable grooves 306 formed on the floating bed body 1. A toothed plate 307 is slidably installed in the movable grooves 306. The placement platform 2 has a plurality of toothed grooves 308 that mesh with the toothed plate 307. One end of a connecting rope 309 is fixedly installed on the slide 303. The other end of the connecting rope 309 passes around the crossbar and is fixedly connected to the toothed plate 307. When the slide 303 and the connecting rope 309 work together to drive the toothed plate 307 to move, the toothed plate 307 can drive the placement platform 2 and the aquaculture tank 6 to rotate, preventing the roots of aquatic plants from growing into the riverbed and keeping the roots suspended in the upper layer of the water body, so that they can preferentially contact the eutrophic surface water. When the slide 303 moves up and down, the connecting rope 309 pulls the toothed plate 307 to slide in the movable grooves 306. The toothed plate 307 meshes with the toothed grooves 308 on the placement platform 2. Therefore, the movement of the toothed plate 307 will drive the placement platform 2 and the aquaculture tank 6 to rotate. Spring 311 is used to provide a reset pull to ensure that toothed plate 307 and toothed groove 308 are always engaged. The rotation of aquatic plant tube 6 can make the roots of aquatic plants evenly contact the water body, avoid the roots from growing excessively towards the riverbed, and at the same time allow the roots to preferentially contact the eutrophic surface water to promote nutrient absorption.
[0024] A boss 310 is fixedly installed on the main body 1 of the floating bed, and a spring 311 is fixedly installed on the boss 310. The other end of the spring 311 is fixedly connected to the toothed plate 307. When the slide 303 pulls the toothed plate 307 to move through the connecting rope 309, the spring 311 is stretched or compressed. When the slide 303 stops moving, the restoring force of the spring 311 keeps the toothed plate 307 in a meshing state with the tooth groove 308, preventing the placement platform 2 from rotating at will. The setting of the spring 311 enhances the stability of the meshing between the toothed plate 307 and the tooth groove 308, ensuring that the position of the placement platform 2 is fixed after rotation adjustment, and avoiding adjustment failure due to water flow impact and other factors.
[0025] A flexible lever 312 is fixedly installed on the lower output shaft of the dual-axis motor 301. The flexible lever 312 is located below the culture tube 6. The lower output shaft of the dual-axis motor drives the flexible lever 312 to rotate. When the flexible lever 312 is located below the culture tube 6, it can gently move the water and the bottom of the culture tube 6. The water flow disturbance can prevent impurities from accumulating at the bottom of the culture tube 6. At the same time, the slight shaking of the culture tube 6 promotes water exchange around the roots, avoids root hypoxia, and improves the quality of the plant growth environment.
[0026] The clamping assembly 5 includes a movable channel 51 opened in the placement platform 2. A clamping rod 52 is slidably installed in the movable channel 51. A rubber pad 53 is provided on the placement platform 2. The upper end of the clamping rod 52 contacts the rubber pad 53. After the breeding tank 6 is placed in the placement platform 2, its own weight drives the clamping rod 52 to move in the movable channel 51 until the clamping rod 52 abuts against the breeding tank 6 itself. At this time, the clamping rod 52 is embedded in the rubber pad 53. When the breeding tank 6 leaves the placement platform 2, the rubber pad 53 can quickly drive the clamping rod 52 to return to its original position. Thus, the breeding tank 6 is quickly installed and removed by its own weight, while ensuring that the breeding tank 6 is stable and does not shake during the movement of the floating bed.
[0027] The dual-axis motor 301 is provided with a motor protective shell 4, which encloses the dual-axis motor 301 to prevent water, mud, and other substances from entering the motor, thus protecting the motor's normal operation, extending its service life, and improving the reliability of the floating bed in a humid water environment.
[0028] Working principle: The output shaft of the dual-axis motor 301 drives the threaded rod 305 to rotate, which in turn moves the slide 303 and the buoyancy plate 304 up and down. By changing the volume of the buoyancy plate 304 submerged in the water, the suspension depth of the main body 1 of the floating bed is adjusted. When the slide 303 moves, it pulls the toothed plate 307 through the connecting rope 309. The toothed plate 307 meshes with the toothed groove 308 of the placement platform 2, which drives the aquaculture cylinder 6 to rotate. The spring 311 maintains the stability of the meshing. The rotation of the aquaculture cylinder 6 makes the roots evenly distributed and prevents them from getting stuck in the riverbed. The flexible lever 312 stirs the water to promote oxygen supply and nutrient absorption of the roots. The rubber pad 53 of the clamping component 5 and the clamping rod 52 cooperate to firmly clamp the aquaculture cylinder 6 and facilitate replacement. The motor protective shell 4 ensures the safe operation of the dual-axis motor 301 in the underwater environment. Through the coordinated work of multiple components, the floating bed can dynamically adjust the depth and the posture of the aquaculture cylinder 6, optimize the root growth environment of aquatic plants, improve the anti-interference ability and aquaculture efficiency, and is suitable for plant cultivation in different water environments.
