Description

Technical Field

[0001] This invention belongs to the field of river water quality treatment technology, specifically relating to a water quality improver dosing device and its working method. Background Technology

[0002] Water quality improvers used in river water treatment primarily work through physical, chemical, or biological processes to inhibit algae growth, remove pollutants, reduce eutrophication, improve transparency and dissolved oxygen, thereby restoring the ecological balance of the water body. Common water quality improvers include phosphorus removal agents, such as polyaluminum chloride (PAC) and iron salts (FeCl3), used to settle phosphates in water; flocculants, such as polyacrylamide (PAM), which promote the settling of suspended particles and algae; oxidants, such as persulfate and ozone tablets, which increase dissolved oxygen and degrade organic matter; microbial preparations containing nitrifying bacteria, denitrifying bacteria, and Bacillus subtilis, used for the biotransformation of nitrogen and phosphorus; and enzyme preparations, which accelerate the degradation of organic matter.

[0003] Common methods for administering water quality improvers include: spreading, targeted application, slow-release device application, and combined aeration application. Spreading is suitable for powder or granular improvers. The improver is evenly spread on the water surface manually or mechanically, relying on natural diffusion and settling. Targeted application is suitable for tablets and blocks, applied at river pollution sources or slow-flowing areas to create localized, highly effective treatment zones. Slow-release device application uses slow-release devices (such as ecological floating islands, net bags, and ceramic carriers) to slowly release the improver, resulting in a longer duration of action. Combined aeration application is suitable for water bodies requiring simultaneous oxygenation, using aeration equipment in conjunction with the addition of microorganisms or oxidants to accelerate water quality recovery.

[0004] The following problems exist with the current water quality improvement agents and urgently need to be addressed:

[0005] 1. Due to the influence of wind and water flow, the distribution of the pesticide is uneven, resulting in excessively high concentrations in some areas and ineffectiveness in others. There is a possibility that the pesticide may drift away with the water flow, leading to low utilization. High concentration areas may cause poisoning of fish and shrimp or instantaneous death of algae, resulting in oxygen depletion.

[0006] 2. Its effective range is limited, only showing results around the application point and failing to cover the entire river channel. Multiple repeated deployments are required, increasing labor and material costs.

[0007] 3. The agent release rate is low, making it unable to quickly treat acute pollution. It requires long-term maintenance and replenishment, increasing subsequent management costs. Long-term use also makes it susceptible to being covered by aquatic plants and sediment, reducing its effectiveness. Summary of the Invention

[0008] To address the aforementioned shortcomings of existing technologies, this invention aims to solve the problems of uneven distribution, short-lived effects, susceptibility to secondary pollution, low agent release rate, high labor costs, and difficulty in sustaining water quality improvement effects by existing water quality improver application methods. The purpose of this invention is to provide a water quality improver application device and its operating method, which combines autonomous navigation, photovoltaic power supply, uniform agent mixing, and spray application functions, and is suitable for ecological restoration and water quality improvement of still or slow-flowing water bodies such as urban rivers, lakes, and reservoirs.

[0009] The present invention adopts the following technical solution: a water quality improver dosing device, comprising:

[0010] The hull is a pontoon structure, welded from steel, with internal reinforcing ribs.

[0011] The propulsion unit, mounted at the stern of the hull, provides power to move the device in the water.

[0012] The photovoltaic modules, with their photovoltaic panels mounted on adjustable brackets above the hull, project downwards to shade the hull. Battery banks are installed on the hull to store the electrical energy converted from the photovoltaic modules. The photovoltaic modules provide clean energy to the system while also providing shade, preventing damage from sunlight and rain. The battery banks power the propulsion system, control box, stirring device, and jetting mechanism.

[0013] The control box, electrically connected to the propulsion unit, battery pack, nozzle, propellant tank, and mixing cylinder, is used to control the operation of the device, including navigation direction, dosage, mixing speed, and spray pattern. It is equipped with a wireless transceiver module for easy path planning, data transmission, and remote control.

[0014] The medicine tank stores powdered water quality improvers, which are then conveyed to the mixing cylinder via a vacuum feeder. By mixing the powdered water quality improvers with cleaned river water, the number of fillings can be reduced, extending the working time.

[0015] The water intake port, located at the bottom of the hull, serves as a channel for river water to enter. A filter screen is installed in the intake port to prevent water tanks, fish, shrimp, and other debris from entering the intake pipe. A filter is also installed on the hull, and the intake pipe connects the filter to the mixing cylinder. The hull rests on the river water, maintaining a water level within the intake port. The hull protects the intake pipe while also conserving its length, preventing damage from bends or collisions when the pipe is positioned on the side of the hull.

[0016] The mixing drum is equipped with a motor-driven agitator to stir and mix the water quality improvement powder and purified river water in the tank.

[0017] The spray nozzle is equipped with multiple horizontally arranged nozzles or spray holes. It is connected to the mixing cylinder via a pump and a solenoid valve to evenly spray the mixed medicine into the water body.

[0018] According to another embodiment of the invention or any of the foregoing embodiments, the launching device wherein the hull is a platform structure, and the interior is divided into multiple independent chambers by steel plates, so that even if some chambers are damaged and flooded, the remaining chambers can still function normally, reducing the probability of sinking.

[0020] According to another embodiment of the invention or any of the foregoing embodiments, the dispensing device has two or more medicine tanks, which are switched by a solenoid valve. Having multiple medicine tanks allows for longer continuous operation, reducing the frequency of refilling medicine powder at shore.

[0021] According to another embodiment of the invention or any of the foregoing embodiments, the dispensing device further includes a water quality monitoring module, comprising a detection chamber and a water quality sensor, which takes a sample from the water intake hole and draws it into the detection chamber; it detects the main water quality parameters of the river water in real time through a dissolved oxygen sensor, a pH sensor, a turbidity sensor, and an ammonia nitrogen / total phosphorus ion selective electrode; it is connected to a control box to transmit the detection data to the control system in real time, and can be stored or transmitted remotely to make a decision on whether to increase the number of dispensing times.

[0022] According to another embodiment of the invention or any of the foregoing embodiments, the delivery device is wherein the nozzle is horizontally installed at the front or rear of the hull, the nozzle is the same length as the hull, and the inclination angle of the nozzle or spray hole on the nozzle to the horizontal plane is adjustable.

[0023] According to another embodiment of the invention or any of the foregoing embodiments, the battery pack is provided with a charging interface. In addition to generating electricity through photovoltaic modules, it can also be charged ashore when power supply is insufficient or needed.

[0024] According to another embodiment of the invention or any of the foregoing embodiments, the launching device further includes a bollard with a cable installed to facilitate stable mooring of the device after it reaches the shore.

[0025] The beneficial effects of this invention are:

[0026] 1.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 , 4As shown, the present invention adopts the following technical solution: a water quality improver dispensing device, comprising a hull 1, which is a pontoon structure welded from steel and reinforced internally. The hull 1 can be a platform structure, internally divided into multiple independent chambers by steel plates, allowing the remaining chambers to continue functioning normally even after some chambers are damaged and flooded, reducing the probability of sinking. It also includes bollards 11, equipped with cables, to facilitate stable mooring of the device after it reaches the shore.

[0038] like Figure 2 , 3 As shown, the thruster 2 is installed at the rear of the hull 1 to provide power and enable the device to move in the water. There are two thrusters 2, arranged symmetrically.

[0039] like Figure 2 , 3 As shown, the photovoltaic module 3, with its photovoltaic panels mounted above the hull 1 via an adjustable bracket 301, projects downwards to shade the hull 1. A battery pack 4 is installed on the hull 1 to store the electrical energy converted by the photovoltaic module 3. The photovoltaic module 3 provides clean energy to the device while also providing shade to prevent sun exposure and rain. The battery pack 4 powers the propeller 2, control box 5, stirring device, and jetting mechanism. An electric telescopic rod is installed at the bottom of the adjustable bracket 301, which monitors the conversion efficiency of the photovoltaic module 3 during extension and retraction to ensure the photovoltaic panels reach the optimal tilt angle. In one example, the battery pack 4 is equipped with a charging interface. Besides generating electricity through the photovoltaic module 3, it can also be charged ashore when power supply is insufficient or needed.

[0040] like Figure 4 , 5 As shown, the control box 5 is electrically connected to the thruster 2, battery pack 4, nozzle 10, medicine tank 6, and mixing cylinder 8. It is used to control the operation of the device, including navigation direction, dosage, mixing speed, and spray mode. It is equipped with a wireless transceiver module for easy path planning, data transmission, and remote control.

[0041] like Figure 5 , 6 As shown, the medicine tank 6 is used to store powdered water quality improver, which is conveyed to the mixing cylinder 8 via a vacuum feeder. The powdered water quality improver, by being mixed with cleaned river water, reduces the number of times the powder needs to be filled, allowing for longer operation. There are two or more medicine tanks 6, switched via solenoid valves. Having multiple medicine tanks 6 allows for longer continuous operation without stopping the machine, reducing the frequency of refilling the powder at the shore.

[0042] like Figure 6As shown, the water intake hole 9 is located at the bottom of the hull 1, serving as a channel for river water to enter. A filter screen is installed in the water intake hole 9 to prevent water tanks, fish, shrimp, and other debris from entering the water intake pipe. A filter 7 is installed on the hull 1, and the water intake pipe connects the filter 7 to the mixing cylinder 8. The hull 1 rests on the river water, and the river water in the water intake hole 9 is kept at the water level. The hull 1 protects the water intake pipe while also saving pipe length and preventing damage from bends or collisions when the pipe is located on the side of the hull 1.

[0043] like Figure 5 , 6 As shown, the mixing cylinder 8 is equipped with a motor-driven agitator to stir and mix the water quality improvement powder and purified river water in the medicine tank 6.

[0044] like Figure 4 , 5 As shown, the nozzle 10 is equipped with multiple horizontally arranged nozzles or spray holes. It is connected to the mixing cylinder 8 via a pump and a solenoid valve to evenly spray the mixed medicine into the water. The nozzle 10 is horizontally installed at the front or rear of the hull 1. The nozzle 10 is the same length as the hull 1, and the tilt angle of the nozzles or spray holes on the nozzle 10 relative to the horizontal plane is adjustable.

[0045] One example also includes a water quality monitoring module, comprising a detection chamber and water quality sensors. Samples are taken from the water intake hole 9 and drawn into the detection chamber. The main water quality parameters of the river water are detected in real time through dissolved oxygen sensors, pH sensors, turbidity sensors, and ammonia nitrogen / total phosphorus ion selective electrodes. The module is connected to the control box 5 to transmit the detection data to the control system in real time, and can be stored or transmitted remotely to make decisions on whether to increase the number of injections.

[0046] Accordingly, a method for operating a water quality improver dosing device is provided, comprising the following steps:

[0047] The first step is to place the device in the target water body and fix it by the bollard 11 or use the thruster 2 to achieve positioning;

[0048] The second step is that photovoltaic module 3 collects solar energy, which is then stored in battery pack 4 to power the entire system.

[0049] The third step is to determine the amount of pesticide to be sprayed per unit of water body based on the water quality test results, and adjust the parameters of navigation speed and pesticide content.

[0050] The fourth step is to draw river water through the water intake hole 9, filter impurities through the filter 7, and then enter the mixing cylinder 8.

[0051] Fifth step: Control box 5 controls the medicine tank 6 to add a specified volume of water quality improver into the mixing cylinder 8, and mixes it thoroughly with the purified river water to form a uniform solution;

[0052] The sixth step involves evenly spraying the liquid into the river channel through nozzle 10, with multiple nozzles achieving multi-point diffusion to ensure rapid distribution of the improver.

[0053] Step 7: The propeller 2 drive unit moves along the planned route to deliver the payload continuously or in sections, thereby increasing the coverage.

[0054] Step 8: After the application is completed and the mixture has fully blended, multiple sampling points are set up along the application path. The water quality is monitored by the water quality monitoring module, and the river water monitoring module collects river water samples from the application area periodically or in real time to monitor changes in water quality parameters before and after application. The data is transmitted to control box 5 for analysis by the application optimization control unit. When the water quality improvement effect is insufficient or the application is excessive, the system automatically adjusts the dosage and spraying frequency. At the same time, the water quality improvement results can be uploaded to a remote platform for regulatory authorities or maintenance personnel to evaluate the treatment effect.

[0055] Working principle of the invention:

[0056] In recent years, rivers, lakes, and other natural or artificial water bodies have generally suffered from eutrophication, blackening and odorization, and excessive pollution loads, with frequent occurrences of algal blooms, insufficient dissolved oxygen, and excessive ammonia nitrogen. In order to quickly improve water quality, inhibit the growth of harmful algae, and increase dissolved oxygen levels, water quality improvers (such as phosphorus removal agents, compound microbial preparations, flocculants, and oxidants) are often used in engineering treatment.

[0057] The existing methods of application are mainly manual, with some mechanical devices using fixed-point application, resulting in low application efficiency and slow drug effectiveness. The water quality improver is not fully mixed with the river water, leading to uneven diffusion. There is a lack of multi-point uniform spraying, resulting in insufficient application coverage. Furthermore, the application is not mobile enough to flexibly adapt to the different water treatment needs.

[0058] The water quality improver dispensing device of the present invention uses a hull 1 as a floating platform, enabling it to float on the surface of rivers or lakes and carry the necessary equipment. A propeller 2 located at the rear of the device provides power, allowing for flexible movement or fixed-point positioning in the water. A photovoltaic module 3 is installed on the top of the hull 1, and its angle is adjusted via an adjustable bracket 301 to improve the utilization rate of solar energy. The photovoltaic module 3 converts solar energy into electrical energy, which is stored in a battery pack 4, thereby powering the propeller 2, control box 5, water pump, stirring device, and spraying system, forming an energy self-sufficiency mode.

[0059] During the deployment process, the device draws river water through the water intake hole 9 at the bottom of the hull 1. The water first enters the filter 7 for preliminary purification to remove silt and suspended impurities, ensuring the stability of the subsequent mixing and spraying process. The purified river water is then sent to the mixing cylinder 8. Under the instruction of the control box 5, the water quality improver in the medicine tank 6 is quantitatively added to the mixing cylinder 8 and thoroughly mixed with the river water to form a uniform concentration of the solution.

[0060] The mixed solution is sprayed into the water through the nozzle 10 system. The nozzles 10 are arranged on both sides and the stern of the hull 1, and are equipped with multiple spray nozzles. The solution is rapidly diffused by the kinetic energy of the spray and the natural flow of the water, achieving uniform distribution and effectively improving the efficiency of the water quality improver.

[0061] The device also includes a river water detection module, which extracts surrounding river water through a sampling unit and uses a water quality sensor array to monitor key indicators such as dissolved oxygen, pH, turbidity, ammonia nitrogen, and total phosphorus in real time. The detection results are sent to control box 5 via a data transmission unit, where they are analyzed by the dosing optimization control unit. When the detection results indicate insufficient or excessive dosing, the system automatically adjusts the dosing rate, mixing intensity, and spraying frequency, thereby achieving closed-loop control of "dosing—detection—feedback—optimization".

[0062] This invention achieves uniform, efficient, and intelligent dosing of water quality improvers through a process of "water intake—filtration—mixing—spraying—detection—feedback". It not only solves the defects of uneven and inefficient existing dosing methods, but also realizes green, intelligent, and quantifiable water environment management through energy self-sufficiency and water quality monitoring modules.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments are merely illustrative of the technical concept and characteristics of the present invention, intended to enable those skilled in the art to understand and implement the invention, and should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
