TECHNICAL FIELD

[0001] The present application belongs to the technical field of cleaning and purifying, and particularly relates to a water area floating object cleaning and water quality purifying device. BACKGROUND

[0002] Lake eutrophication is a typical water ecological problem caused by excessive input of exogenous nutrients such as nitrogen and phosphorus. Its characteristic performance is the transition of water body from oligotrophic state to eutrophic state, which further leads to abnormal proliferation of algae, sharp reduction of water transparency and sharp drop of dissolved oxygen content, and finally causes degradation of water ecological system function and imbalance of structure. Although the formation mechanism of blue-green algae bloom has been deeply analyzed by the academic circle, the current treatment of most eutrophic water bodies is still limited to end-point emergency disposal, and it is difficult to achieve long-term ecological restoration. Especially in the outbreak period of water bloom, how to build an emergency treatment system with timeliness and sustainability is still a difficult point to be broken through in the field of environmental engineering. The current emergency disposal technologies for blue-green algae bloom mainly include physical, chemical and biological methods: physical methods such as aeration flow generation can inhibit the aggregation of algae by disturbing the water body; chemical methods can achieve rapid algae inhibition by adding algicides, but there is a risk of secondary pollution; biological methods rely on microbial metabolism to digest pollutants, but are significantly restricted by environmental conditions. Although the above methods have their own characteristics, they all have the problems of limited applicability of single technology, strong ecological disturbance and high treatment cost. Therefore, based on the formation mechanism of blue-green algae bloom, combined with multiple parameters such as hydrodynamic characteristics, environmental carrying capacity and ecological risk threshold, an integrated emergency treatment scheme of multi-technology coupling is constructed, so a water area floating object cleaning and water quality purifying device which is simple to operate, high in working efficiency, green, environmentally friendly, saves manpower and material resources and is easy to maintain is needed.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] Example 1 The invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1 As shown, this invention provides an emergency algae removal and purification device based on visual recognition, integrating surface debris cleaning, water quality monitoring, and purification functions. It is suitable for the treatment of eutrophic waters such as lakes and rivers. It includes: Waste collection module 35 is used to identify and collect floating debris on the water surface; Water filtration module 36 is used to adsorb pollutants in water and purify water quality; Power module 38 drives the movement and navigation of the water surface debris cleaning and water purification device; The device's energy module supplies power to all modules; The intelligent control system coordinates the control of the waste collection module, water filtration module, power module, and energy module of the device. The intelligent control system uses visual recognition technology to locate floating objects and links the power module to achieve precise garbage collection. At the same time, it dynamically adjusts the water filtration module based on water quality monitoring data.

[0031] like Figure 2 and 3 As shown, the waste collection module 35 is a key component for cleaning floating debris on the water surface, working closely with the visual recognition system, power module, and main control system. This module includes a conveyor belt power system driven by a stepper motor 11. The motor shaft 47 rotates, which in turn drives the conveyor belt 32, causing the conveyor belt 41 to rotate and enabling the waste collection conveyor belt 12 to operate normally. The conveyor belt surface is equipped with anti-slip ridges and conveyor belt baffles 40 to enhance waste adhesion and create directional flow channels. Camera brackets 34 are installed on both sides of the device, each carrying a camera 4. A large visual recognition model 5 (based on the YOLOv4 algorithm) identifies the coordinates of floating debris in real time. The intelligent control system (microcontroller 3) uses this coordinate data to intelligently adjust the differential speed of the propeller 14 via the propeller motor shaft 24, driving the entire device to precisely approach the target waste. When the device reaches the waste area, the conveyor belt 41 starts, effectively transporting the waste into the waste collection bin 18. The design of the conveyor belt skirt 39 and conveyor belt baffle 40 can effectively reduce the rebound of garbage caused by water flow impact and significantly improve collection efficiency.

[0032] The water filtration module 36 is the core component for water purification, working in conjunction with the water pump, detection probe, and main control system. For example... Figure 4 As shown, the module consists of a water filtration tank 10, a composite filter element, and a conductivity meter 7. The water filtration tank 10 features a cleverly designed three-layer staggered filter structure: a coarse filter layer 27 intercepts large particles; a zeolite layer 28 (modified zeolite, ion exchange capacity 170 mg / g) adsorbs ammonia nitrogen through ion exchange; and a biochar layer 29 (MgO-modified biochar, particle size 1-2 mm) removes phosphates through physical adsorption and chemical bonding. The three filter layers are separated by filter screens 22. A water pump 17, controlled by a pump power regulator 43, draws water in through the pump inlet 20 and discharges it through the outlet 19 to the filter tank inlet 48, allowing the water to enter the filtration system for purification. The purified water is then discharged through the filter tank outlet 15. To prevent excessive water pressure, a seepage hole 33 is provided at the bottom of the filter tank, through which purified water can also be discharged. The conductivity meter 7 monitors the water conductivity in real time and transmits the data to the intelligent control system (microcontroller 3) via data cable 16. The intelligent control system correlates ammonia nitrogen concentration using a linear model. Once the detected value exceeds a preset threshold, it automatically switches to enhanced filtration mode and optimizes the ratio of zeolite to biochar to ensure water purification efficiency. The filter box door 50 features a detachable design, greatly facilitating filter replacement and maintenance.

[0033] The power module 38 is responsible for the device's motion and precise navigation, working in conjunction with the intelligent control system, BeiDou positioning system, and camera. Power primarily comes from symmetrically arranged propellers 14, whose blades 26 are connected to the motor 13 via the propeller shaft 25. The intelligent control system (microcontroller 3, STM32H7 dual-core architecture) receives real-time positioning data from BeiDou satellites 23 and camera 4 via signal receiver 6, and uses a Kalman filter algorithm to correct trajectory deviations, thereby precisely controlling the differential steering of propellers 14 (response time < 0.2s), achieving precise navigation and automatic obstacle avoidance (safe distance 20cm). Navigation data is transmitted back to the user terminal via signal transmission antenna 42, enabling remote monitoring and operation.

[0034] like Figure 5 and 6 As shown, the energy module provides continuous and stable power support for the entire device and is closely linked to the light sensor, battery, and intelligent control system. This module mainly includes a photovoltaic panel 1 and a battery 2. The photovoltaic panel 1 intelligently maintains a 30° tilt angle via an angle adjustment shaft 44 to maximize solar radiation reception, charging the battery 2 on sunny days. On cloudy or rainy days, the system automatically switches to energy storage mode, powered by the battery 2. The battery 2 (rated voltage 11.1V, capacity 12Ah) provides continuous power to the device. When the battery level drops below 10%, the power alarm light 45 triggers an alarm, and the device autonomously plans and returns to its initial position for charging via the BeiDou positioning system, ensuring long-term operation and ease of recovery. Furthermore, data from the light sensor 46 assists in energy management and optimizes charging and discharging strategies.

[0035] like Figure 7 As shown, the intelligent control system uses a single-chip microcomputer 3 as the main control core to realize intelligent management and coordination of various modules. The intelligent control system integrates a WiFi communication module 8 and Bluetooth 49, enabling real-time data interaction with a mobile app 9. Users can conveniently view water quality data (conductivity, ammonia nitrogen concentration), control device operating mode (automatic / manual), monitor power consumption, and locate the device in real time through the app 9. The water quality data collected by the detection probe 31 is transmitted to the single-chip microcomputer 3 via data cable 16, while the relay 30 precisely controls the start and stop of the water pump switch 21 and motors (such as stepper motor 11 and motor 13) according to the instructions of the intelligent control system. This series of data transmission and control mechanisms forms a closed-loop control of "detection-processing-feedback", ensuring the efficient, accurate, and intelligent operation of the device.

[0036] Overall operation process of the device After the device is started, the intelligent control system first activates the large visual recognition model 5 and camera 4 to scan and identify floating debris on the water surface. The intelligent control system (microcontroller 3) then plans the optimal cleaning path in conjunction with the Beidou positioning system 6. Subsequently, the power module 38 drives the propeller 14 to precisely propel the device to the target area. Once arrived, the conveyor belt 41 in the waste collection module 35 starts to effectively collect the floating debris into the waste collection bin 18. At the same time, the water pump 17 in the water filtration module 36 starts to work, drawing water into the filtration tank 10, where it is purified through layers of composite filters before being discharged. During this process, the conductivity meter 7 provides real-time feedback of water quality data to the intelligent control system (microcontroller 3), which dynamically adjusts the water purification strategy based on the data to ensure the purification effect. The device's energy module automatically switches the power supply modes of the photovoltaic panel 1 and the battery 2 based on the data from the light sensor 46, ensuring that the device can operate stably around the clock, achieving seamless integration and efficient collaboration between floating debris cleaning and water purification.

[0037] It should be understood that any parts not described in detail in this specification belong to the prior art.

[0038] It should be understood that the above description of the preferred embodiments is quite detailed, but it should not be considered as a limitation on the scope of protection of this invention. It is neither necessary nor possible to exhaustively describe all possible implementations. Those skilled in the art, under the guidance of this invention, can make substitutions or modifications without departing from the scope of protection of this invention, and all such substitutions or modifications fall within the scope of protection of this invention.
