Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment and aquaculture equipment, and more specifically, it relates to a tracking-type integrated water quality management system. Background Technology

[0002] Current river water treatment mainly relies on technologies such as aeration, chemical dosing, and bioremediation, but these generally suffer from high energy consumption and operating costs. For example, aeration equipment (such as blowers and flow promoters) typically requires 1.5–5 kW of power, and continuous operation results in electricity costs accounting for over 40% of the total treatment cost; chemical dosing systems rely on high-power stirring pumps (≥1.5 kW) and frequent opening and closing of solenoid valves, which not only increases energy consumption but also causes secondary pollution due to uneven chemical settling; biofilm reactors require continuous oxygen supply and circulating water flow, resulting in energy consumption as high as 3–8 kWh / m³. 3 Existing water treatment systems rely on municipal electricity, which is energy-intensive. Therefore, solar panel power technology has emerged as a solution.

[0003] A search revealed Chinese patent application publication number CN106342744A, published on January 25, 2017, which discloses a mobile solar-powered oxygenation system and method. The oxygenation system includes a buoyancy support mechanism, a solar power supply mechanism, a power mechanism, an oxygenation mechanism, a lifting mechanism, and a control mechanism. The control mechanism includes a central controller and a dissolved oxygen sensor, an ultrasonic ranging module, a GPS navigation module, and an inertial navigation module, all electrically connected to the central controller. Based on feedback from the ultrasonic ranging module, GPS navigation module, and inertial navigation module, the central controller controls the rotation speed of two drive motors to achieve mobile oxygenation and automatic berthing. The electrical energy generated by the solar power supply mechanism is stored in a battery and used to power the oxygenation mechanism, power mechanism, and control mechanism. The solar power supply mechanism includes a solar panel, a telescopic rod, and a column. The column is mounted on a support plate, with a support frame hinged to its top. The solar panel is mounted on this support frame. The telescopic rod is hinged to the lower middle part of the column, with its other end hinged to the support frame. This system can change the horizontal tilt angle of the solar panel by adjusting the length of the telescopic rod, making it as perpendicular to the direction of sunlight as possible, thus achieving a higher photoelectric conversion efficiency. Secondly, the column can rotate relative to the support plate, so that when the support plate rotates, the solar panel can be controlled to always face the direction of sunlight. However, this system requires manual control of the solar panel's orientation towards sunlight, and the hinged design with the telescopic rod makes the structure for controlling the rotation of the solar panel too complex, and the hinge is prone to damage.

[0004] Therefore, how to achieve the structural stability of a tracking-based integrated water quality management system is an urgent problem to be solved. Summary of the Invention

The support cylinder has at least one connecting member fixed to it, and the connecting member is hinged to the solar panel. The rotating shaft is rotatably connected inside the support cylinder, with a first connecting rod connected to an eccentric position at each end of the shaft. The other end of each first connecting rod is connected to a second connecting rod, which is connected to the solar panel. The first and second connecting rods are hinged. In operation, the connecting member serves as a support point for the solar panel. When the rotating shaft rotates, the first connecting rod pushes the second connecting rod, causing the solar panel to swing along the support point.

[0015] In one possible implementation of this utility model, a support base is provided on the back surface of the solar panel, a support node is provided on the side of the support base, the support node is hinged to the connector, and the second connecting rod is fixedly connected to the support base.

[0016] In one possible embodiment of this utility model, the rotating shaft is connected inside the support cylinder via a bearing.

[0017] In one possible embodiment of this utility model, the oxygenation unit is connected to several air pipes, which extend into the water body, and a section of the air pipe extending into the water body is fixed with an air stone, which is wrapped with a grid packing.

[0018] In one possible embodiment of this utility model, a spring is installed inside the trachea, with one end of the spring connected to the oxygenation unit above the base and the other end connected to the air stone.

[0019] As one possible embodiment of this utility model, the water quality monitoring unit further includes a chlorophyll a meter;

[0020] An ultraviolet (UV) irradiation unit is installed at the bottom of the base and / or the bottom of the float. The UV irradiation unit includes a transparent waterproof container and a UV lamp, with the UV lamp placed inside the transparent waterproof container.

[0021] As one possible embodiment of this utility model, the water quality monitoring unit further includes an online ammonia nitrogen detector;

[0022] It also includes a microbial agent dispensing unit, which is installed on the base. The bottom of the microbial agent dispensing unit is connected to a microbial agent dispensing pipe, which extends into the water body. A solenoid valve is installed on the microbial agent dispensing pipe to control whether the substance in the microbial agent dispensing pipe is introduced into the water body and to control the flow rate of the substance in the pipe into the water body.

[0023] As one possible implementation of this utility model, it also includes an Internet of Things (IoT) monitoring unit located on the base. The IoT monitoring unit is electrically connected to the water quality monitoring unit, the oxygenation unit, the ultraviolet light unit, and the solenoid valve, and is used to monitor the water quality and control the operation of the oxygenation unit, the ultraviolet light unit, and the solenoid valve.

[0024] As one possible embodiment of this utility model, it also includes a waterproof enclosure, which houses a controller, energy storage device, oxygenation unit, microbial agent dispensing unit, and Internet of Things monitoring unit; a support rod is installed outside the waterproof enclosure, and a photosensitive sensor receiver is installed at the end of the support rod.

[0025] 3. Beneficial effects

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] (1) In the system of this utility model, the photosensitive sensor detects the direction of high light intensity and drives the solar panel to face this direction, making the most of solar energy, significantly improving the energy conversion efficiency of the solar panel, reducing energy waste, greatly increasing the storage capacity of electrical energy, providing power for the long-term operation of the system, eliminating the need for an external power source, reducing dependence on mains power, especially suitable for areas without grid coverage, with low long-term operating costs, achieving energy saving and environmental protection;

[0028] (2) The system of this utility model uses a drive mechanism to drive the solar panel to swing to a position with strong light intensity. The drive mechanism uses at least one connector to act on the solar panel as a support point, and works with the first connecting rod to push it eccentrically, changing the angle between the first connecting rod and the second connecting rod to form the swing temperature of the solar panel. The structure of the drive mechanism is simple and stable, which improves the service life of the system, saves costs, and further realizes energy saving and environmental protection.

[0029] (3) In the system of this utility model, the water quality monitoring unit integrates a dissolved oxygen meter, a chlorophyll a meter, and an online ammonia nitrogen meter to realize real-time detection of dissolved oxygen concentration, chlorophyll a concentration, and ammonia nitrogen concentration in the water. At the same time, based on the monitoring data, the closed-loop control system can dynamically adjust the oxygenation amount and provide early warnings for chlorophyll a and ammonia nitrogen concentrations according to the actual dissolved oxygen concentration in the water. It can indirectly reduce the chlorophyll a concentration by controlling low-intensity ultraviolet light to inhibit algae growth. The ammonia nitrogen warning can be used to promptly add water purification bacteria to prevent water quality deterioration. This achieves the function of water quality management. At the same time, the Internet of Things monitoring unit supports remote monitoring and fault early warning, which improves the intelligent management level of the system.

[0030] (4) In the system of this utility model, the air stone connected to the oxygenation unit is wrapped with a grid packing. The grid-air stone synergistic structure not only prevents the air stone from clogging, but also forms a biofilm carrier, which helps to degrade organic pollutants in the water, thereby ensuring a stable oxygenation effect and achieving stable oxygenation efficiency.

[0031] (5) The system of this utility model is easy to maintain. The components of each unit can be quickly disassembled and replaced, which reduces the difficulty and cost of maintenance. Attached Figure Description

[0037] Traditional equipment has only a single function of oxygenation or water quality testing. The equipment relies on mains power or fixed solar panels, which has high energy consumption and low light utilization rate. Long-term maintenance of water bodies requires the combined operation of multiple different devices, which can easily lead to energy waste or time delays, resulting in water quality deterioration.

[0038] The present invention will now be described in conjunction with specific embodiments and accompanying drawings.

[0039] Example 1

[0040] like Figure 1 The illustration shows a tracking-type integrated water quality management system, including a support unit 1, a power supply unit, a water quality monitoring unit 3, and an oxygenation unit 4. The support unit 1 floats on the water surface and is used to fix and support the power supply unit, water quality monitoring unit 3, and oxygenation unit 4. The power supply unit efficiently utilizes solar energy and converts it into electrical energy to power the system's electrical equipment. The water quality monitoring unit 3 detects water quality data, such as dissolved oxygen content, and determines whether to use the oxygenation unit 4 to supply oxygen to the water based on the detection data. For system safety, this embodiment includes a waterproof enclosure 8 to isolate the electrical components on the support unit 1 from the water, reducing the risk of equipment damage.

[0041] Specifically, the support unit 1 includes a base 11 and a float 12 disposed at the bottom of the base 11 or penetrating the base 11; the float 12 floats on the water, so that the base 11 is located above the water surface, and serves to support the equipment of each unit of the system.

[0042] The power supply unit, mounted on the base 11, includes several solar panels 21, a transmission mechanism 22, a controller 23, a photosensitive sensor receiver 24, and an energy storage device 25. The base 11 is arranged with as many solar panels 21 as possible around its perimeter to absorb solar energy. The photosensitive sensor receiver 24 is mounted outside the waterproof housing 8 via a support rod to sense the intensity and direction of sunlight and send signals to the controller 23. The controller 23 drives the transmission mechanism 22 to rotate, causing each solar panel 21 to swing towards a direction with high sunlight intensity, adjusting it in real time to follow the sun's direction. Each solar panel 21 converts solar energy into electrical energy, which is stored in the energy storage device 25 as the system's power source. For example, it drives the aeration unit 4 to aerate the water, and the air diffuses into the water through the air pipe 41 to the air stone 42, supplying oxygen to the water.

[0043] In this embodiment, the photosensitive sensor receiver 24 is a commercially available illuminance meter, and the controller 23 can be any device that can realize the function of this embodiment using existing technology, such as the solar brushless controller described in the patent publication number CN107834913B. The energy storage device 25 is a battery with a capacity of 800AH and an output voltage of 220V, which supports the system to operate for 72 hours under continuous cloudy and rainy conditions.

[0044] It is important to note that the transmission mechanism 22, being a vulnerable structure, directly affects the rotational stability and lifespan of the solar panel 21. Figure 2 As shown, the transmission mechanism 22 in this embodiment includes a support cylinder 221, a connecting member 222, a rotating shaft 223, a first connecting rod 224, and a second connecting rod 225. At least one connecting member 222 is fixed to the support cylinder 221. In this embodiment, for stable connection, a pair of connecting plates are symmetrically arranged on the support cylinder 221 as connecting members 222. The connecting members 222 are hinged to the solar panel 21 and fixedly welded to the support cylinder 221. The rotating shaft 223 is connected to the inner wall of the support cylinder 221 via ball bearings. The power driving the rotating shaft 223 to rotate comes from a motor. In this embodiment, a stepper motor is used for the rotating shaft 223. One of its advantages is precise positioning, eliminating the need for encoder feedback. The rotor angle is directly controlled by controlling the number of pulses, such as 1.8° or 0.9° per pulse, achieving a positioning accuracy of ±0.05°. The first connecting rod 224 is connected to the eccentric positions at both ends of the rotating shaft 223. During the rotation of the rotating shaft 223, the first connecting rod 224 is driven to move forward and backward. The other end of the first connecting rod 224 is connected to the second connecting rod 225, allowing the angle between the first connecting rod 224 and the second connecting rod 225 to change. The second connecting rod 225 is connected to the solar panel 21, wherein the first connecting rod 224 and the second connecting rod 225 are hinged. In the working state, the connecting member 222 acts on the solar panel 21 to form a support area. When the rotating shaft 223 rotates, the first connecting rod 224 pushes the second connecting rod 225, causing the solar panel 21 to swing along this support area.

[0045] To further increase the stability of the connection between the transmission mechanism 22 and the solar panel 21, a support base 211 is provided on the back surface of the solar panel 21, a support node 212 is provided on the side of the support base 211, the support node 212 is hinged to the connector 222, and the second connecting rod 225 is fixedly connected to the support base 211.

[0046] The water quality monitoring unit 3 includes one or more of the following: a dissolved oxygen meter, a chlorophyll a meter, and an online ammonia nitrogen meter. Each detection probe penetrates the base 11 and extends into the water body. In this embodiment, the water quality monitoring unit 3 is equipped with a dissolved oxygen meter, a chlorophyll a meter, and an online ammonia nitrogen meter. The dissolved oxygen meter has a measurement range of 0-20 mg / L, the chlorophyll a meter has a measurement range of 0-500 μg / L, and the online ammonia nitrogen meter has a measurement range of 0-20 mg / L. It measures the dissolved oxygen concentration, chlorophyll a concentration, and ammonia nitrogen concentration in the water body in real time. Based on the detection results: the dissolved oxygen in the water body is increased through the oxygenation unit 4; the chlorophyll a concentration is indirectly reduced by controlling low-intensity ultraviolet light irradiation through the ultraviolet light unit 5 to inhibit algae growth; and water purification bacteria are promptly added through the bacterial agent dosing unit 6 to prevent water quality deterioration. Specifically:

[0047] The oxygenation unit 4 uses an oxygenation pump and is connected to multiple air pipes 41. Each air pipe 41 extends into the water, and an air stone 42 is fixed to the end of each air pipe 41 that extends into the water. The air stone 42 is wrapped with a grid packing material 43, the pore size of which is ≤1cm. This grid-air stone synergistic structure not only prevents the air stone from clogging but also forms a biofilm carrier, which helps degrade organic pollutants in the water, thus ensuring a stable oxygenation effect and achieving stable oxygenation efficiency. To prevent the multiple air pipes 41 from tangling, each air pipe 41 is equipped with a spring for support. One end of the spring is connected to the oxygenation unit 4 above the base 11, and the other end is connected to the air stone 42.

[0048] The ultraviolet irradiation unit 5 uses a 13W, 50Hz-60Hz low-intensity LED ultraviolet lamp to avoid the oxidation byproducts such as hydroxyl radicals that may be generated by high-intensity ultraviolet irradiation. It is installed in a transparent waterproof container at the bottom of the base 11 and / or the bottom of the float 12 to irradiate the water with ultraviolet light.

[0049] The microbial agent dispensing unit 6 is installed on the base 11. The bottom of the microbial agent dispensing unit 6 is connected to the microbial agent dispensing pipe 61, which extends into the water. A solenoid valve 611 is installed on the microbial agent dispensing pipe 61 to control whether the substance in the microbial agent dispensing pipe 61 is introduced into the water and to control the flow rate of the substance in the pipe into the water.

[0050] For ease of monitoring, this embodiment also includes an Internet of Things (IoT) monitoring unit 7, such as the IoT monitoring device disclosed in CN113691593B, which is mounted on the base 11. The IoT monitoring unit 7 is electrically connected to the water quality monitoring unit 3, the oxygenation unit 4, the ultraviolet light unit 5, and the solenoid valve 611 to monitor the water quality and control the operation of the oxygenation unit 4, the ultraviolet light unit 5, and the solenoid valve 611.

[0051] In this embodiment of a tracking-type integrated water quality management system, on a sunny day, after the system is started, the horizontally placed solar panel 21 relies on the photosensitive sensor receiver 24 to detect that the initial light intensity has increased to 2000 lux, and transmits the signal to the controller 23, which instructs the rotating shaft 223 to rotate 20° in one direction to drive the solar panel 21 to rotate with the sun's position. During the process, the light intensity is continuously fed back, and the position of the solar panel 21 is constantly adjusted to ensure maximum efficiency in utilizing solar energy.

[0052] like Figure 3 As shown, the water quality monitoring unit 3 monitors water temperature, dissolved oxygen, chlorophyll a, and ammonia nitrogen concentration online and feeds this information back to the controller 23. Based on the set dissolved oxygen value, the controller activates or deactivates the aeration unit 4. When the water temperature exceeds the set limits of 20℃ and the chlorophyll a value exceeds 40μg / L, the ultraviolet light unit 5 is activated to inhibit algae growth. When the ammonia nitrogen concentration exceeds 3mg / L, the IoT monitoring unit 7 sends a warning message to the staff. The staff then add bacteria to the bacterial agent dosing unit 6, and the controller 23 controls the solenoid valve 611 to slowly release the ammonia nitrogen purification bacterial agent through the dosing pipe.

[0053] The microbial agent dispensing unit 6 has an agent inlet at the top and is connected to an agent dispensing pipe 61 at the bottom. After the water quality monitoring unit 3 detects that the ammonia nitrogen level in the water exceeds the standard, it issues a warning to the staff via the IoT monitoring unit 7. After the staff dispenses the microbial agent, the controller 23 opens the solenoid valve 611 based on the liquid level signal from the microbial agent dispensing unit, and the agent dispensing pipe 61 slowly releases the microbial agent into the water. When the liquid level signal reaches 0.01m, the controller 23 closes the solenoid valve 611 and sends a signal to the staff via the IoT monitoring unit 7. The IoT monitoring unit 7 is used to remotely monitor the device's operating status, dissolved oxygen concentration, chlorophyll a concentration, ammonia nitrogen concentration, and other data, and generates monthly and annual reports.

[0054] The above description is illustrative of the present invention and its embodiments. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
