Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lake water treatment technology, and in particular relates to a device for the remediation of pollutants in urban lakes. Background Technology
[0002] In today's rapid urbanization process, urban lakes are facing unprecedented environmental pressure. Large amounts of untreated sewage are being discharged into these lakes, polluting the water bodies and severely squeezing the living space of aquatic organisms. As a result, lakes are facing a severe situation where large numbers of fish die and the aquatic ecosystem is on the verge of collapse.
[0003] However, traditional physical remediation methods, such as mechanical dredging, while able to remove pollutants accumulated on the lakebed in the short term, have limitations such as high cost, potential for secondary pollution, and ineffectiveness against dissolved pollutants. During mechanical dredging, the resuspension of bottom sediment not only increases water turbidity but may also release previously deposited pollutants back into the water, exacerbating water quality deterioration. Chemical methods, such as adding chemical agents, can rapidly reduce pollutant concentrations, but excessive or improper use can disrupt the aquatic ecological balance, harm aquatic life, and hinder long-term ecological restoration.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0022] This utility model embodiment provides a device for remediating pollutants in urban lakes, such as... Figure 1-4 As shown, the urban lake water pollutant remediation device includes: a shell 2 that can be placed in the urban lake water, with floats 1 symmetrically fixedly installed on the bottom of the shell 2; an assembly frame 3 symmetrically arranged on the shell 2 and with adjustable height; a placement frame 4 fixed on the assembly frame 3, with a planting basket 5 for planting water purification plants on the placement frame 4; and an adjustment mechanism set inside the shell 2 for controlling the raising and lowering of the assembly frame 3.
[0023] In this embodiment, the shell 2 serves as the main frame of the entire repair device, providing a mounting base and protection for other components. It houses and protects the internal adjustment mechanism, ensuring stable cooperation among the components. The presence of the float 1 is crucial; on the one hand, it utilizes the principle of buoyancy to allow the entire device to float steadily on the surface of the urban lake. The height-adjustable feature of the mounting frame 3 is a significant advantage. As the water-purifying plants grow, their requirements for light and dissolved oxygen in the water vary at different stages. For example, during the seedling stage, a shallower water depth may be needed to obtain sufficient light and avoid excessive water flow; during the vigorous growth stage, a deeper water depth may be necessary to obtain richer aquatic nutrients. The assembly rack 3 can precisely adjust its height according to these needs, ensuring that the water-purifying plants in the planting basket 5 are always in the most suitable growth environment, maximizing their water purification efficiency. The placement rack 4, which is fixed on the assembly rack 3, is equipped with the planting basket 5 for planting water-purifying plants. The placement rack 4 plays a connecting role, stably supporting the planting basket 5 and ensuring the stability of the planting layout of the water-purifying plants. The water-purifying plants in the planting basket 5 gently and continuously absorb nutrients such as nitrogen and phosphorus, as well as some organic pollutants in the water through their natural growth and metabolism. The purification process is green and environmentally friendly, and will not cause additional burden on the aquatic ecology, which is conducive to the long-term stable restoration of the inland lake ecology.
[0024] In a further preferred embodiment of this utility model, the adjusting mechanism includes: a mounting bracket 6 fixedly installed inside the housing 2, on which a mounting shell 7 is fixedly installed; a screw 8 rotatably installed inside the mounting shell 7, the screw 8 threaded through the mounting bracket 3; a motor 9 fixedly installed inside the mounting bracket 6 for driving the screw 8 to rotate, the output shaft of the motor 9 being fixedly connected to the screw 8 via a coupling; and a guide rod 10 fixedly installed inside the mounting shell 7, the guide rod 10 passing through the mounting bracket 3 for limiting and guiding its movement.
[0025] In this embodiment, the mounting frame 6 serves as the basic support structure of the entire adjustment mechanism, firmly fixed inside the housing 2. The screw 8 is one of the core driving components for raising and lowering the assembly frame 3. When the motor 9 drives it to rotate, the rotational motion of the screw 8 can be precisely converted into the linear raising and lowering motion of the assembly frame 3 using the principle of screw drive. The motor 9 starts and drives the screw 8 to rotate, raising the height of the assembly frame 3, allowing the water-purifying plants in the planting basket 5 to receive more light. When water temperature changes affect the dissolved oxygen distribution in the water, the motor 9 can adjust the water depth of the assembly frame 3 as needed, creating the best growth conditions for the water-purifying plants and realizing the intelligent operation of the device. The guide rod 10 plays an indispensable auxiliary and protective role in the adjustment mechanism. When the screw 8 drives the assembly frame 3 to rise and fall, the guide rod 10 provides a stable linear motion trajectory for the assembly frame 3, preventing the assembly frame 3 from shifting or shaking due to the torque generated by the rotation of the screw 8 or external interference.
[0026] In a further preferred embodiment of the present invention, the placement rack 4 is provided with a through groove for placing the planting basket 5, and a limiting plate 11 for fixing the planting basket 5 is fixedly installed on the placement rack 4 by bolts 12.
[0027] In this embodiment, the design of the channel is ingenious, providing a precise placement position for the planting basket 5. On one hand, compared to randomly placed planting baskets, the channel defines the position of the planting basket 5, ensuring that it will not easily shift or shake during device operation, even when faced with external forces such as lake waves. This significantly improves stability compared to traditional planting carriers without precise positioning structures. For example, in windy weather, when the lake water fluctuates violently, without the channel for fixation, the planting baskets 5 might collide and scatter, affecting the growth of the water-purifying plants. The channel effectively avoids such problems, ensuring the orderly purification of the water by the water-purifying plants. The limiting plate 11, together with the bolts 12, further strengthens the fixing effect on the planting basket 5.
[0028] In a further preferred embodiment of the present invention, the front end and the rear end of the housing 2 are symmetrically fixedly installed with connecting groove blocks 13, and the groove blocks 13 are provided with assembly holes.
[0029] In this embodiment, the layout of the recessed blocks 13 has multiple practical values. In terms of expanding the purification scale, it breaks the limitations of a single device's purification capacity. When facing large-area polluted urban lakes, the various remediation devices are no longer isolated. With the help of the recessed blocks 13, they can be assembled like a collage. Figure 1 Multiple devices are tightly connected to form a continuous "purification defense line." For example, near the lake's inlet, pollutants flow in in concentrated amounts. Connecting multiple devices allows for centralized and continuous purification of the large influx of wastewater, greatly improving overall purification efficiency—something traditional single-unit remediation devices cannot achieve. Considering the practical convenience of deployment and management, the recessed block 13 also plays a crucial role. When transporting the device to the designated location on the lake surface, the lifting equipment can precisely hook onto the recessed block 13, achieving stable and accurate deployment, reducing the risk of device damage due to placement deviations and the difficulty of subsequent adjustments.
[0030] In a further preferred embodiment of the present invention, a positioning plate 14 is fixedly installed on the housing 2, and the positioning plate 14 is provided with mounting holes for assembling ropes to fix the housing 2.
[0031] In this embodiment, the positioning plate 14 provides strong assurance for the positioning and fixation of the entire device in the lake. Compared with the absence of a dedicated positioning structure, it provides a dedicated and stable attachment point for subsequent rope connections. In the complex and ever-changing lake environment, external forces such as wind, waves, and water currents constantly act on the device. Without the positioning plate 14, the ropes may drift randomly due to a lack of reliable fixation or insecure fixation, making it impossible to accurately position the device in the area most in need of purification, thus affecting the purification effect.
[0032] In a further preferred embodiment of the present invention, support columns 17 are symmetrically fixedly installed inside the housing 2, and a sunshade shell 18 for sunshade and rain protection is assembled at the top of the support columns 17.
[0033] In this embodiment, the support column 17 provides a solid support structure for the entire device, and the shielding shell 18 can provide shade and rain protection, preventing a large amount of rainwater from entering the shell 2.
[0034] In a further preferred embodiment of the present invention, a solar panel 16 is provided on the shielding shell 18, and a battery power supply box 15 adapted to the solar panel 16 is provided inside the shell 2.
[0035] In this embodiment, the solar panel 16 is innovatively designed, fully utilizing the natural advantages of the open, unobstructed, and abundant sunlight resources surrounding the urban lake. Compared to traditional restoration devices that rely solely on external mains power, the solar panel 16 opens up a new path for self-sufficient power supply. During daily operation, whether driving the motor 9 in the adjustment mechanism to precisely adjust the height of the assembly frame 3 to meet the needs of different growth stages of the water-purifying plants, or continuously powering various environmental monitoring sensors to ensure real-time collection of data such as light and water temperature, providing a basis for the intelligent operation of the device, the solar panel 16 can stably output electrical energy, greatly reducing dependence on the external power grid and lowering long-term operating costs.
[0036] In a further preferred embodiment of the present invention, a lighting lamp for illumination is provided on the top of the shielding shell 18, and a detachable inspection plate is assembled on the mounting shell 7 by screws.
[0037] In this embodiment, the installation of lighting greatly facilitates nighttime maintenance and monitoring of the urban lake; the design of the inspection plate provides a convenient channel for daily maintenance and troubleshooting of the device. Compared with the enclosed mounting shell 7, when problems occur in the adjustment mechanism, such as screw 8 jamming or motor 9 overheating, requiring maintenance, staff only need to unscrew the screws and remove the inspection plate to directly access the internal components, quickly locate the root cause of the problem, and repair or replace parts.
[0038] In summary, the shell 2 provides support and protection for each component, while the float 1 ensures stable buoyancy of the device. The assembly frame 3 flexibly adjusts its height according to the different growth stages of the water-purifying plants, working in conjunction with the placement frame 4 and the planting basket 5 to allow the water-purifying plants to grow in a suitable environment, efficiently purifying the water in a green way and maintaining the ecology of the inner lake. In the adjustment mechanism, the mounting frame 6 stabilizes the foundation, and the screw 8, driven by the motor 9, precisely converts the motion form to raise and lower the assembly frame 3. The guide rod 10 assists in ensuring stable operation, realizing intelligent control and ensuring the growth conditions of the water-purifying plants. The through groove of the placement frame 4 precisely positions the planting basket 5, and the limit plate 11 and bolts 12 reinforce it, enhancing the stability of the device under complex lake conditions and allowing the water-purifying plants to continue purifying without external interference.
