Description

Technical Field

[0001] This utility model relates to the field of ecological water body restoration technology, and in particular to an ecological floating bed device suitable for lake water body restoration. Background Technology

[0002] As a highly efficient water quality remediation technology, ecological floating beds can effectively reduce the content of pollutants such as COD, nitrogen, and phosphorus in water bodies through ecological functions such as absorption by aquatic plants and degradation by microorganisms, thus constructing an artificial ecological purification system. With aquatic plants as the core, it makes full use of water nutrient resources and plays an important role in the management of water environments such as lakes and rivers.

[0003] However, existing ecological floating beds have significant shortcomings in practical applications. During the application of ecological restoration floating beds, when slender aquatic plants grow on the floating bed, they often extend beyond the surface of the bed. Their overall wind resistance is weak, especially in the early stages of growth when their roots are not firmly planted in the riverbed. When encountering extreme weather such as strong winds and thunderstorms, they are prone to lodging, with adjacent plants squeezing each other and even detaching from the outer surface of the floating bed. This not only hinders normal plant growth but also increases the risk of plant damage, leading to a decrease in ecological restoration efficiency. At the same time, the work of clearing and replanting lodged plants is cumbersome, significantly increasing the cost and workload of manual maintenance. It is evident that the existing technology has certain defects and shortcomings, and therefore, it needs to be improved and designed. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an ecological floating bed device suitable for lake water restoration, which can more accurately solve the problems described above.

[0007] The telescopic protective mechanism includes an outer sleeve and an adjustment component. The adjustment component is installed inside one side of the floating bed frame. The outer sleeve is fixedly connected to the outside of the floating bed frame and is also connected to the support frame. An annular groove is provided inside the outer sleeve, and a telescopic protective sleeve is slidably connected inside the annular groove. The outside of the adjustment component and the inside of the telescopic protective sleeve are fixedly connected.

[0008] Furthermore, the adjustment assembly includes a guide rail and a mounting sleeve. The mounting sleeve is fixedly connected to the upper end of one side inside the floating bed frame. The guide rail is fixedly installed on the lower end of the side of the floating bed frame near the mounting sleeve. A waterproof motor is fixedly connected inside the mounting sleeve. A lead screw is fixedly connected to the output end of the waterproof motor through the mounting sleeve. The lead screw is rotatably connected to the inside of the guide rail. A sliding block is threaded onto the outer surface of the lead screw. A connecting arm is fixedly connected to the bottom of the sliding block. The outer end of the connecting arm is fixedly connected to the inner side of the telescopic protective sleeve.

[0009] Furthermore, a sliding reserved groove is provided inside the outer sleeve near the connecting arm, and the connecting arm is slidably connected to the inside of the sliding reserved groove. The sliding block has a regular hexagonal shape when viewed from below, and the overall cross-section of the guide rail has an isosceles trapezoidal shape when viewed from below.

[0010] Furthermore, the energy storage mechanism includes a waterproof box, inside which are a battery and a microcontroller.

[0013] Furthermore, a water guide ring is fixedly installed on the outer side of the hollow floating ring, and the overall cross-sectional shape of the water guide ring is set to rhombus.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device features intelligent telescopic protection, effectively improving plant survival rates. It works by linking a wind speed sensor with a microcontroller to provide intelligent protection for aquatic plants. When the wind speed sensor detects excessive wind, the signal is transmitted to the controller, activating the waterproof motor. This drives the lead screw to move the sliding block, which in turn extends the telescopic protective sleeve. The hexagonal sliding block and the isosceles trapezoidal guide rail structure ensure the protective sleeve unfolds stably and evenly, wrapping around the floating bed frame and providing physical support for the aquatic plants. This protects them from strong winds, preventing them from falling over or being crushed, effectively improving plant survival rates under extreme weather conditions, reducing manual maintenance costs, and enhancing the environmental adaptability of the ecological floating bed.

[0016] 2. This device features efficient energy storage and water guidance protection, effectively ensuring stable operation. During use, the device utilizes the special shape of the vertical shaft turbine blades to efficiently convert kinetic energy into electrical energy under the impact of water flow, which is stored in the battery to power various components, achieving self-sufficiency and reducing operating costs. At the same time, the diamond-shaped water guiding ring on the outside of the hollow floating ring diverts and guides the water flow with its sharp edges, reducing the impact force on the floating bed, reducing swaying, avoiding eddy interference, and protecting the floating bed structure and plant growth environment. The synergy between hydropower generation and water guidance protection enhances the stability and sustainability of the device's operation. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] An ecological floating bed device suitable for lake water body restoration includes a hollow floating ring 1, a support frame 2 fixedly installed on the inner side of the hollow floating ring 1, a floating bed net frame 3 fixedly installed on the inner side of the support frame 2, a telescopic protective mechanism 4 fixedly installed on the outer side of the floating bed net frame 3, and an energy storage mechanism 5 installed in the middle of the interior of the floating bed net frame 3.

[0026] The telescopic protective mechanism 4 includes an outer sleeve 41 and an adjusting component 42. The adjusting component 42 is installed inside one side of the floating bed frame 3, and the outer sleeve 41 is fixedly connected to the outside of the floating bed frame 3. The outside of the outer sleeve 41 is also connected to the support frame 2. An annular groove 43 is provided inside the outer sleeve 41, and a telescopic protective sleeve 44 is slidably connected inside the annular groove 43. The outside of the adjusting component 42 is fixedly connected to the inside of the telescopic protective sleeve 44. During the application of this device, when it is necessary to protect the aquatic plants inside the floating bed frame 3, the adjusting component 42 is activated. The power output of the adjusting component 42 drives the component fixedly connected to the inside of the telescopic protective sleeve 44 to move, so that the telescopic protective sleeve 44 slides in the annular groove 43. Since the outer sleeve 41 is fixedly connected to the floating bed frame 3 and the support frame 2, the telescopic protective sleeve 44 smoothly expands or contracts along the annular groove 43 of the outer sleeve 41, thereby adjusting the protection range of the floating bed frame 3 and providing corresponding physical protection for the aquatic plants.

[0027] Combination Figures 1-5 As shown, the adjustment component 42 includes a guide rail 421 and a mounting sleeve 422. The mounting sleeve 422 is fixedly connected to the upper end of one side inside the floating bed frame 3. The guide rail 421 is fixedly installed on the lower end of the side of the floating bed frame 3 near the mounting sleeve 422. A waterproof motor 423 is fixedly connected inside the mounting sleeve 422. The output end of the waterproof motor 423 passes through the mounting sleeve 422 and is fixedly connected to a lead screw 424. The lead screw 424 is rotatably connected to the inside of the guide rail 421. A sliding block 425 is threadedly connected to the outer surface of the lead screw 424. A connecting arm 426 is fixedly connected to the bottom of the sliding block 425. The outer end of the connecting arm 426 is fixedly connected to the inner side of the telescopic protective sleeve 44. A sliding reserved groove 45 is opened inside the outer sleeve 41 near the side of the connecting arm 426. The connecting arm 426 is slidably connected to the inside of the sliding reserved groove 45. The sliding block 425 is a regular hexagon in shape when viewed from below. The overall cross-section of the guide rail 421 is an isosceles trapezoid in shape when viewed from below.

[0028] In the technical solution described in the above-mentioned embodiment of this application, during the application of this device, when the wind speed sensor 55 detects that the wind force reaches the preset threshold in windy weather, the waterproof motor 423 starts and drives the lead screw 424 to rotate in the guide rail 421. Due to the special design of the sliding block 425, which is a regular hexagon and the guide rail 421 is an isosceles trapezoid, the sliding block 425 connected to the outer surface of the lead screw 424 can only move in a straight line along the guide rail 421 without rotating. The connecting arm 426 at the bottom of the sliding block 425 moves synchronously with the sliding block 425 and slides in the sliding reserved groove 45, thereby driving the telescopic protective sleeve 44 to slide smoothly in the annular groove 43, realizing the expansion or contraction of the protective sleeve. When strong winds require protection, its extension can cover and protect the floating bed frame 3, thereby preventing the vegetation planted inside the floating bed frame 3 from collapsing or even falling off due to strong winds. It provides dynamic protection for the aquatic plants inside the floating bed frame 3, and it has intelligent control, which can improve the overall intelligent protection function of this device during use.

[0029] Example 2

[0030] Combination Figures 1-4 As shown, the energy storage mechanism 5 includes a waterproof box 51, inside which are a battery and a microcontroller. A hydroelectric generator 52 is fixedly connected to the bottom of the waterproof box 51. A vertical axis turbine blade 53 is fixedly installed at the bottom of the shaft of the hydroelectric generator 52. A support rod 54 is fixedly connected to the top of the waterproof box 51. A wind speed sensor 55 is fixedly connected to the top of the support rod 54. The vertical axis turbine blade 53 is generally arranged in a cone shape that spreads from top to bottom. The vertical axis turbine blade 53 is generally arranged in a spiral twisted shape. A support ring 56 is fixedly connected to the bottom of the vertical axis turbine blade 53. A connecting frame 6 is fixedly installed at the bottom of the outer sleeve 41. A connecting rope 7 is fixedly connected to the bottom of the connecting frame 6. A fixed anchor rod 8 is fixedly connected to the outer end of the connecting rope 7. A water guide ring 9 is fixedly installed on the outer side of the hollow floating ring 1. The overall cross-sectional shape of the water guide ring 9 is set as rhombus.

[0031] In the technical solution described in the above-described embodiments of this application, when the lake water flows during the application of this device, the water flow impacts the vertical axis turbine blades 53, which are arranged in a conical shape that spreads downwards and is spirally twisted. The uneven force on the curved surface of the blades generates torque, which drives the shaft of the hydroelectric generator 52 to rotate, converting water energy into electrical energy. The generated electrical energy is stored in the battery in the waterproof tank 51 to power the entire ecological floating bed device. The single-chip microcomputer controller receives the wind speed data monitored by the wind speed sensor 55 at the top of the support rod 54 and controls the telescopic protective mechanism according to the preset program. While other components such as structure 4 are in operation, the diamond-shaped cross-section water guide ring 9 on the outer side of the hollow floating ring 1 can divert water flow with its sharp edges and corners, reducing the direct impact of water flow on the floating bed and guiding the water flow to both sides along the surface of the water guide ring 9, reducing the swaying amplitude of the floating bed and avoiding eddy current interference with the stability of the floating bed. The floating bed is fixed to a specific position in the lake by the bottom connecting frame 6 of the outer sleeve 41, the connecting rope 7 and the fixed anchor 8 to ensure the stability of the device. The support ring 56 enhances the structural stability of the vertical shaft turbine blades 53 and ensures the continuous and efficient operation of the hydropower generation process.

[0032] The waterproof motor 423 in this device is a Techtronic Micro Motor 28GA-775, with a rated voltage of 12V / 24V selectable, a power of 30W, a waterproof rating of IP68, a built-in gearbox, and a torque of 2.5N・m. It is suitable for long-term operation in humid environments.

[0033] The battery model is Sail Gel Battery 6-QW-60, with a rated voltage of 12V, a capacity of 60Ah, a deep cycle life of ≥300 cycles, and a vibration-resistant gel electrolyte, making it suitable for floating environments on water.

[0034] The microcontroller controller is model STM32F103C8T6, which features an ARM Cortex-M3 core, a 72MHz main frequency, 64KB Flash, waterproof packaging, and supports multiple ADC / DAC interfaces to meet the needs of sensor data acquisition and motor control.

[0035] The 52 hydro generator is a miniature axial-flow turbine generator, model ANDRITZ Hydro HammerfestMHK-200.

[0036] The wind speed sensor model 55 is Shandong Renke RS-FS-N01-2. It operates on the ultrasonic principle, with a measurement range of 0-60m / s, an accuracy of ±0.1m / s, a response time of <0.5s, an IP66 protection rating, and RS485 digital output.

[0037] Meanwhile, the waterproof housing 51 contains a sensor signal conditioning module, specifically the Texas Instruments ADS1115, a 16-bit ADC converter with 4-channel differential input, I2C interface, and low power consumption (150μA), used for signal acquisition from the wind speed sensor 55.

[0038] It also features a charge / discharge controller, model MPPT100 / 50Tr, with maximum power point tracking (MPPT) technology, supports automatic 12V / 24V identification, has an efficiency of ≥98%, a waterproof casing, and is suitable for wind power generation and battery management. The waterproof enclosure 51 also houses a wireless communication module, model SIM800L, which is a quad-band GSM / GPRS module with an operating temperature of -20℃ to +70℃. It supports SMS and GPRS data transmission and enables remote monitoring.

[0039] The working principle and advantages of this utility model are as follows: This device, through the cooperation of the telescopic protective mechanism 4 and the intelligent control module, achieves dynamic protection for aquatic plants. When the wind speed sensor 55 at the top of the support rod 54 detects that the wind force reaches the preset threshold, it transmits the signal to the single-chip microcomputer controller in the waterproof box 51. The controller then starts the waterproof motor 423 in the adjustment component 42. The motor drives the lead screw 424 to rotate, which drives the sliding block 425 connected by the thread on the outer surface to move in the guide rail 421. The sliding block 425 pulls the telescopic protective sleeve 44 in the annular groove 4 through the connecting arm 426. Extending inwards, the sliding block 425 is hexagonal and the guide rail 421 is isosceles trapezoidal, ensuring stable sliding without deviation. The connecting arm 426 slides synchronously within the sliding pre-reserved groove 45, ensuring the telescopic protective sleeve 44 unfolds evenly. The fully unfolded telescopic protective sleeve 44 wraps around the outside of the floating bed frame 3, providing physical support for aquatic plants extending from the floating bed surface, resisting the impact of strong winds, and preventing plants from falling over, being crushed, or falling out. This design not only improves the survival rate of plants under extreme weather conditions but also reduces the amount of manual maintenance, significantly enhancing the environmental adaptability of the ecological floating bed.

[0040] The energy storage mechanism 5 of this device achieves efficient energy conversion and utilization through a special design. The vertical axis turbine blades 53 adopt a conical, spirally twisted structure that diffuses from top to bottom. This shape causes the blades to generate greater torque due to uneven force on the curved surface under the impact of water flow. As the water flow diffuses from the top to the bottom of the blades, it continuously drives the blades to rotate, which in turn drives the shaft of the hydroelectric generator 52 to rotate and generate electricity. The generated electrical energy is stored in the battery in the waterproof tank 51, which powers the telescopic protection mechanism 4, wind sensor and other components, so that the device does not need to be connected to an external power source, which can reduce its operating cost. In addition, the diamond-shaped water guide ring 9 on the outside of the hollow floating ring 1 can effectively divert the water flow with its sharp edges, reducing the direct impact of the water flow on the floating bed and reducing the swaying amplitude of the floating bed. The water flow is guided to both sides along the diamond-shaped surface of the water guide ring 9 to avoid the formation of eddies that interfere with the stability of the floating bed, protecting the floating bed structure and the internal plant growth environment. The combination of hydroelectric power generation and water guide protection design enables the device to achieve energy self-sufficiency and improves the overall stability and sustainability of operation.

[0041] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
