Description

A floating bed frame for a submerged plant planting device Technical Field

[0001] This utility model relates to the field of aquatic ecological restoration, and more specifically, to a floating bed frame for a submerged plant planting device, which is particularly suitable for the ecological restoration of shallow lakes. Background Technology

[0002] Submerged plants play a crucial role in lake ecosystems because they absorb nutrients, secrete allelochemicals to inhibit algal growth and reproduction, and provide diverse habitats for other aquatic organisms. Furthermore, submerged plants are not only the main primary producers in shallow lake ecosystems but also important biological measures for controlling pollution loads and improving water quality. Particularly in shallow lake ecosystems, submerged plants play a key role in the reversal of algal-dominated turbid water stability to grass-dominated clear water stability. Restoring submerged vegetation is a crucial link in rebuilding a healthy aquatic ecosystem, maintaining good water quality and rich biodiversity in shallow lakes.

[0003] In real-world environments, the growth of submerged plants is limited by environmental factors such as water depth, temperature, pH, light intensity, and turbidity. Among these, underwater effective light intensity is considered one of the most important factors affecting the growth and distribution of submerged plants, and insufficient underwater light is a direct cause of their demise. Water depth and turbidity are two main reasons why changes in underwater light intensity can weaken underwater effective light intensity. In water, light attenuation depends on wavelength and light quality, both of which vary with water depth. As water depth increases, the ratio of red to far-red light increases, leading to morphological changes in submerged plants. Simultaneously, submerged plants are typically shade-loving plants; excessive light inhibits photosynthesis, affecting their normal growth and development. Different submerged plants have different water level tolerances, and the amplitude, frequency, timing, duration, and rate of change of water level all influence aquatic vegetation. Ecological floating bed technology, as an in-situ remediation and control technology for eutrophic water bodies, has been widely researched and applied. Ecological floating beds are generally planted with submerged plants. However, existing floating beds for planting submerged plants have certain shortcomings. For example, Chinese utility model patent CN211080122U discloses a protective device for planting submerged plants on river and lake banks, including an outer fixing frame. The bottom of the outer fixing frame has two fixedly connected posts on both sides. A first support rod is fixedly connected to the center of the top of the inner cavity of the outer fixing frame, and a second support rod is fixedly connected to the center of the left side of the inner cavity of the outer fixing frame. The inner cavity of the fixed frame is equipped with a planting trough. Fixed rods are fixedly connected to the four corners of the inner cavity of the planting trough. A fixed ring is fixedly connected to the end of each fixed rod away from the outer fixed frame. A soil-sealing groove is opened in the inner cavity of the fixed ring. A potting soil cover net is fixedly connected to the inner cavity of the potting soil cover net. An elastic tightening ring is fixedly connected to the inner cavity of the elastic tightening ring. A tightening groove is fixedly connected to the inner cavity of the elastic tightening ring. A rigid fixing ring is fixedly connected to the bottom of the fixed ring. A hollow groove is opened in the inner cavity of the rigid fixing ring. A cultivation net is fixedly connected to the bottom of the rigid fixing ring. A potting soil filling groove is opened in the inner cavity of the cultivation net. The connection between the floating bed frame and the floating bed is a single-layer structure, which is easily affected by wind and waves, leading to detachment. It lacks an adaptive design for the growth of submerged plants. Furthermore, the structure of the floating bed frame is complex, resulting in poor fixation to the floating bed. Under the continuous action of wind, waves, or water flow, the floating bed is prone to movement or deformation, causing it to detach from the frame, affecting the structural stability of the planting device. Additionally, the manufacturing cost is high, and its practicality is limited. Summary of the Invention

[0004] This utility model aims to overcome at least one of the defects (deficiencies) of the prior art and provides a floating bed frame for a submerged plant planting device. It solves the problems of poor fixation between the floating bed and the frame, the floating bed moving or deforming under the continuous action of wind and waves, thus detaching from the frame and affecting the structural stability of the planting device, as well as the problems of complex structure, high manufacturing cost, and poor practicality.

[0005] The technical solution adopted by this utility model is a floating bed frame for a submerged plant planting device, including a first frame, a second frame and multiple support rods. The first frame and the second frame are both quadrilateral structures, with a certain vertical distance between them, and the first frame is set above the second frame. The support rods are arc-shaped and are set between the first frame and the second frame, with one end connected to the first frame and the other end connected to the second frame.

[0006] The device is fixed to a floating bed, which is typically a quadrilateral structure with curved inner or outer surfaces. Therefore, the floating bed frame is also quadrilateral. This frame consists of a first frame and a second frame, both made of metal. Curved support rods are positioned between the first and second frames, forming a groove-like structure. The radius of curvature of the support rods is 1.2 to 1.5 times the thickness of the floating bed. A certain vertical distance must be maintained between the first and second frames, the distance depending on the thickness of the floating bed. In use, the frame is installed on the inner or outer surface of the floating bed, engaging the inner or outer surface within the groove. After engagement, the first frame is positioned on the upper surface of the floating bed, and the second frame on the lower surface. This is then secured with ropes for a more robust fixation and increased strength of the double-layer structure. The entire device is constructed from a quadrilateral frame structure and several curved steel pipes. Its simple structure, low manufacturing cost, and high practicality allow for mass production as needed.

[0007] Furthermore, the support rods set on the four sides of the quadrilateral protrude to the opposite side, and the support rods set at the four corners protrude to the opposite corner.

[0008] By setting the support rods on the four sides of the quadrilateral to protrude towards the opposite side, and setting the support rods at the four corners to protrude towards the opposite corner, the opening of the groove faces outward. This allows the frame to be placed on the inner side of the floating bed. Compared with placing the frame on the outer side of the floating bed, this arrangement can save materials and reduce the weight of the frame.

[0009] Furthermore, the area enclosed by the first frame is larger than the area enclosed by the second frame.

[0010] The area enclosed by the second frame is set relatively small to facilitate the installation of the skeleton. After the skeleton is manufactured, it is placed on the floating bed. Under its own weight or by applying a certain pressure, the skeleton can be installed inside the floating bed. After installation, the first frame needs to be located on the upper side of the floating bed to prevent the skeleton from sliding down. Therefore, the area enclosed by the first frame needs to be set relatively large.

[0011] Furthermore, the ratio of the area enclosed by the first frame to the area enclosed by the second frame is 1:0.98 to 0.96.

[0012] After the skeleton is installed, the first frame and the second frame should fit as close as possible to the inner side of the floating bed. If the second frame is too small, the arc formed by it and the first frame will not fit the inner side of the floating bed. Therefore, the ratio of the area enclosed by the first frame to the area enclosed by the second frame is set to 1:0.98 to 0.96.

[0013] Furthermore, the distance between two adjacent support rods is 0.8 to 1.2 m.

[0014] In use, the floating bed provides upward support to the first frame, preventing it from sliding down. The planting buckets, used for submerged plants, are suspended on the second frame, exerting a downward pulling force. The support rods positioned between the first and second frames must be strong enough to withstand this pulling force to prevent damage to the frame. While maintaining structural strength, the distance between adjacent support rods cannot be too large; otherwise, the weight of the planting buckets might bend the second frame. Conversely, if the distance between adjacent support rods is too small or the number of rods is too high, it will increase the frame's weight. Therefore, the distance between adjacent support rods is set between 0.8 and 1.2 meters.

[0015] Furthermore, multiple first floats are provided on the second frame, and the multiple first floats are evenly distributed on the second frame.

[0016] The second frame is located below the first frame. During use, the planting bucket is suspended from the second frame. This lowers the stress point of the entire frame, resulting in greater structural stability. However, the downward pull of the planting bucket on the second frame could potentially pull it below the water surface, making it inconvenient to operate the planting bucket during observation. By installing multiple first floats on the second frame, the buoyancy of these floats can be used to keep the second frame above the water surface. The first floats are evenly distributed on the second frame to ensure balanced stress distribution. Preferably, the distance between two adjacent first floats is 0.7–1.3 m.

[0017] Furthermore, multiple limiting rods are provided on the four sides of the first frame. One end of each limiting rod is connected to the first frame, and the other end extends toward the arc-shaped opening of the support rod. The other end of each limiting rod is provided with a downward hook.

[0018] The arc-shaped opening of the support rod points in the direction of the float's installation. After the frame is installed on the float, it is securely tied with nylon ropes. However, because the float is constantly moved by wind, waves, and currents, the nylon ropes will loosen over time, causing the distance between the float and the frame to increase or even detach. A limiting rod is installed on the first frame, extending from above the float to the other side. This limits the float, preventing it from increasing the distance between itself and the frame or detaching. Furthermore, the limiting rod also prevents the frame from sliding down. The length of the limiting rod is 1 / 3 to 1 / 2 of the width of the float.

[0019] Furthermore, the limiting rod is located above the support rod, and the horizontal distance between it and the nearest support rod is no more than 5cm.

[0020] The limiting rod is above the first frame and applies an upward force to the first frame, while the support rod is below the first frame and applies a downward force to the first frame. Setting the horizontal distance between the limiting rod and the support rod close together can ensure the stability of the first frame and prevent the first frame from being bent.

[0021] Furthermore, the second frame is provided with crisscrossing pull ropes between opposite sides. These pull ropes are flexible and are evenly distributed to form a mesh structure.

[0022] The floating bed is typically made of flexible material and expands outwards due to wind, waves, and currents, causing the central parts of the four sides of the frame structure to expand outwards as well. Interlocking guy ropes are installed between opposite sides of the second frame to prevent the frame and floating bed from expanding outwards, providing a stabilizing effect. When observing submerged plants, small boats need to approach the floating bed, inevitably resulting in contact with it. Using flexible guy ropes provides impact resistance, preventing damage to the floating bed from collisions with the small boat. The guy ropes are made of nylon or polyethylene with a tensile strength ≥500N.

[0023] Furthermore, the unit grid area of ​​the mesh structure is 1.5–3.5 m². 2 Furthermore, a second float is provided at the intersection of the pull ropes.

[0024] Some submerged plants may have vines. A rope can be used for the vines to climb, creating a downward pull on the rope. A first buoy can be attached to the rope, and its buoyancy can create an upward force on the rope. Since climbing vines may block sunlight, the area of ​​each grid cell should not be too small to prevent the vines from blocking sunlight and thus affecting the growth of the submerged plants.

[0025] Compared with existing technologies, the advantages of this invention are as follows: The skeleton is designed with a double-layer structure, increasing its own strength while making its connection with the floating bed more secure. The skeleton includes a first frame, a second frame, and support rods. The support rods are arc-shaped, with their curvature matching the inner or outer surface of the floating bed, forming a concave groove structure with the first and second frames. When connected to the floating bed, the inner or outer surface of the floating bed is located within the groove, resulting in tighter contact with the skeleton. A certain vertical distance is maintained between the first and second frames. After installation, the first frame is located on the upper side of the floating bed, and the second frame is located on the lower side, allowing for locking and securing the skeleton to the floating bed more firmly. Furthermore, the support rods on the four sides of the quadrilateral protrude towards opposite sides, and the support rods at the four corners protrude diagonally, causing the groove openings to face outwards. This allows the skeleton to be positioned on the inner surface of the floating bed, saving material and reducing the skeleton's weight. Setting the second frame slightly smaller than the first frame facilitates the installation of the framework. During installation, simply place the framework on the floating bed; the framework will be installed under its own weight or by applying downward pressure. After installation, the first frame, second frame, and support rods will all be tightly fitted against the inner surface of the floating bed. In use, the planting container is suspended from the second frame. The framework's lower stress point makes the structure more stable. To ensure the second frame remains above the water surface for easy operation of the planting container, multiple first buoys are also installed on it. The floating bed is typically made of flexible material, and its center may expand outwards due to waves or currents. Therefore, multiple crisscrossing ropes are installed between opposite sides of the second frame, forming a mesh structure. This prevents the floating bed from expanding outwards and also provides a climbing surface for some submerged plant vines. To prevent vines from blocking sunlight and to avoid pulling the ropes into the water, each grid unit has an area of ​​1.5–3.5 m². 2 A second buoy is placed at the intersection of the guy ropes. When observing submerged plants, a small boat needs to approach the floating bed, inevitably resulting in contact with it. Making the guy ropes flexible helps to resist impact and prevent damage to the floating bed from collisions. The arc-shaped support rod design significantly improves resistance to wind and waves by dispersing stress. This device has a simple structure, is easy to construct, has low manufacturing costs, and is highly practical, allowing for mass production as needed. Attached Figure Description

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0035] As shown in Figures 1 to 3, a floating bed frame for a submerged plant planting device includes a first frame 1, a second frame 2, and multiple support rods 3. Both the first frame 1 and the second frame 2 are square frame structures. The side length of the first frame 1 is 4m, and the side length of the second frame 2 is 3.92m. They are separated by a certain vertical distance H, and the first frame 1 is positioned above the second frame 2. The area S1 enclosed by the first frame 1 is larger than the area S2 enclosed by the second frame 2. As shown in Figures 5 and 7, the floating bed 5 is a quadrilateral structure with an upper side, a lower side, an inner side, and an outer side. The distance between the upper and lower sides is the thickness H1 of the floating bed, and the distance between the inner and outer sides is the width B of the floating bed. Both the inner and outer sides are arc-shaped.

[0036] During installation, first align the floating bed frame with the inner side of the floating bed 5, then apply downward pressure to the floating bed frame to move it downwards, thereby making it fit against the support rod 3 and the inner side of the floating bed 5. Because the first frame 1 is relatively large, when the floating bed frame moves downwards to a certain extent, the floating bed 5 prevents the frame from moving further downwards.

[0037] The support rod 3 is arc-shaped, with its curvature matching the curvature of the inner surface of the floating bed 5. It is positioned between the first frame 1 and the second frame 2, with one end connected to the first frame 1 and the other end connected to the second frame 2. The radius R of the support rod 3 is 1.2 to 1.5 times the thickness H1 of the floating bed 5 to distribute stress and improve its resistance to wind and waves. The support rods 3 positioned on the four sides of the first frame 1 and the second frame 2 protrude towards the opposite side, while the support rods 3 positioned at the four corners protrude diagonally to ensure better contact with the inner surface of the floating bed 5. The distance L between two adjacent support rods 3 is 1 meter.

[0038] As shown in Figure 1, to ensure that the second frame 2 remains above the water surface, multiple first buoys 21 are installed on the second frame 2. These first buoys 21 are evenly distributed on the second frame 2, with a spacing L3 between adjacent first buoys 21 of 0.7–1.3 m. To prevent the outward expansion of the floating bed 5 from exerting an outward pulling force on the frame, multiple crisscrossing tension ropes 22 are evenly arranged between opposite sides of the second frame 2. The tension ropes 22 are made of nylon or polyethylene and have a tensile strength of not less than 500 N. The multiple tension ropes 22 form a mesh structure, with each unit grid area S3 of 1.5–3.5 m². 2 Furthermore, a second float 23 is provided at the intersection of the mesh structure.

[0039] As shown in Figures 1 and 3, multiple limiting rods 4 are also provided on the first frame 1. One end of each limiting rod 4 is connected to the first frame 1, and the other end extends outward with a downward hook at its end. The limiting rod 4 is positioned above the support rod 3, with a horizontal distance L1 between it and the support rod 3 not exceeding 5 cm, as shown in Figure 4. Preferably, the limiting rod 4 is positioned directly above the support rod 3. The length L2 of the limiting rod 4 is 1 / 3 to 1 / 2 of the width B of the floating bed.

[0040] As shown in Figures 5 and 6, the floating bed frame is installed on the inner side of the floating bed 5 during use and fixed to the floating bed with nylon ropes 51. The planting bucket 6 is connected to the second frame. After installation, the first frame 1 is located on the upper side of the floating bed 5, and the second frame 2 is located on the lower side of the floating bed 5. The first frame 1, the second frame 2, and the support rod 3 are all attached to the inner side of the floating bed 5, and the limiting rod 4 is attached to the upper side of the floating bed 5, with its hook located on the outer side of the floating bed 5. The vertical distance H between the first frame 1 and the second frame 2 is set according to the thickness H1 of the floating bed 5. Preferably, the ratio of the vertical distance H between the first frame 1 and the second frame 2 to the thickness H1 of the floating bed is 0.7 to 0.9:1. Compared with the traditional single-layer frame, the fixing strength of this utility model is increased by 30%.

[0041] As shown in Figure 8, fixing rods 7 are installed at four angles of the floating bed frame. One end of the fixing rod 7 is inserted into the riverbed at the bottom of the water, and the other end protrudes above the water surface. The fixing rods 7 are connected to the floating bed frame using fixing ropes 71. The fixing ropes 71 are flexible ropes, thereby fixing the floating bed 5 and the frame in the horizontal direction and allowing the floating bed 5 to rise or fall with the water level.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model.
