Detailed Implementation

[0018] The present invention will be further described below.

[0019] This utility model provides a solar water treatment device, mainly used for sewage treatment in remote areas. It includes a shell 1 with a left chamber 11 and a right chamber 12. The left chamber 11 contains a filtration unit 3, and the right chamber 12 contains a disinfection and sterilization unit 4. The filtration unit 3 and the disinfection and sterilization unit 4 are connected by a pipe 14. A water pump 2, connected to the filtration unit 3, is located outside the shell 1 for water inlet. An outlet 16, connected to the right chamber 12, is located at the bottom of the shell 1. The filtration unit 3 includes a filter layer 31, a fiber layer 32, and an ultrafiltration membrane layer 33 arranged sequentially from top to bottom. The water pump 2 is connected to the filter layer 31 via the pipe 14. The disinfection and sterilization unit 4 includes an ultraviolet lamp 41 installed on the inner wall of the right chamber 12 and a dispensing device 42 for adding silica photocatalyst powder installed beside the ultraviolet lamp 41. Multiple sets of ultraviolet lamps 41 and dispensing devices 42 are installed on the inner wall of the right chamber 12. The top of the shell 1 is... A photovoltaic panel assembly 5 is electrically connected to the water pump 2 and the disinfection and sterilization unit 4. The photovoltaic panel assembly 5 includes a solar photovoltaic panel 51 and a battery assembly 52. ​​The solar photovoltaic panel 51 is provided with a bracket 51 connected to the top of the housing 1. The battery assembly 52 is electrically connected to the solar photovoltaic panel 51. The photovoltaic panel assembly 5 is also electrically connected to a control unit 6. The control unit 6 includes a data acquisition module and a control module. The data acquisition module includes a sensor assembly 611 set at the water outlet 16 for monitoring water quality and a display 612 set on the outside of the housing 1. The display 612 is signal-connected to the sensor assembly 611. The control module includes a controller A621 for adjusting the flow rate of the water pump 2, a controller B622 for adjusting the intensity of the ultraviolet lamp 41, and a controller C623 for controlling the amount of silica photocatalyst powder dispensed by the dispenser 42. The controllers A621, B622, and C623 are electrically connected to the display 612.

[0020] like Figures 1-4As shown, the solar water treatment device includes a housing 1, which is divided into a left chamber 11 and a right chamber 12 by a partition 13. A filtration unit 3 is installed in the left chamber 11, and a disinfection and sterilization unit 4 is installed in the right chamber 12. Water to be treated enters from the left chamber 11, passes through the filtration unit 3 and the disinfection and sterilization unit 4, and exits from the right chamber 12, thus achieving water treatment. The filtration unit 3 has three layers of filtration, including a filter layer 31, a fiber layer 32, and an ultrafiltration membrane layer 33 arranged from top to bottom. The filter layer 31 serves as a preliminary filter to remove larger particles; the fiber layer 32 adsorbs odors, organic pollutants, and some heavy metal ions in the water; and the ultrafiltration membrane layer 33 removes bacteria, viruses, and small suspended solids. This three-layer composite filter design significantly improves the filtration effect and filter life, and allows for filter replacement to adapt to different water qualities. The disinfection and sterilization unit 4 includes an ultraviolet lamp 41 installed on the inner wall of the right chamber 12 and a dispenser 42 for dispensing silica photocatalyst powder installed on the side of the ultraviolet lamp 41. Multiple sets of ultraviolet lamps 41 and dispensers 42 are installed on the inner wall of the right chamber 12. Water treated by the left chamber 11 flows into the right chamber 12. The ultraviolet lamps 41 on the side wall of the right chamber 12 emit light, and the silica photocatalyst powder is released through the dispenser 42 and comes into contact with the water. Through photocatalytic reaction, it decomposes harmful substances in the water, achieving the effect of disinfection and sterilization. The dispenser 42 uses an existing stepper motor to drive a screw feeder with an accuracy of ±0.1g / time. The dispensing amount is controlled by a controller C623, adjustable from 0.1-0.5g / L. The storage compartment of the dispenser 42 is located on the side wall of the right chamber 12 and adopts a moisture-proof and sealed design. The dual synergistic disinfection mechanism is more thorough than a single method and reduces chemical residues. The structure is compact, easy to carry outdoors, and quick to assemble and disassemble. A photovoltaic panel assembly 5 is installed on the top of the housing 1. This photovoltaic panel assembly 5 is electrically connected to the water pump 2 and the disinfection and sterilization unit 4, and supplies power to the ultraviolet lamp 41 and the silica photocatalyst dispenser 42 in the water pump 2 and the disinfection and sterilization unit 4. The photovoltaic panel assembly 5 includes a solar photovoltaic panel 51 and a battery assembly 52. ​​The solar photovoltaic panel 51 converts solar energy into electrical energy and stores it in the battery assembly 52. ​​The battery assembly 52 then supplies the power to the components in the solar water treatment device that require power. To facilitate the installation of the solar photovoltaic panel 51, a bracket 51 for installing the solar photovoltaic panel 51 is provided on the top of the housing 1. When the device is running, the solar photovoltaic panel 51 converts solar energy into electrical energy and stores it in the battery assembly 52, providing continuous power support for the water treatment device. This ensures that the device can operate efficiently and stably, providing a clean drinking water solution for remote areas. When the power is sufficient, it is stored for backup. When the power is insufficient, core functions, such as ultraviolet disinfection, are prioritized.The photovoltaic panel assembly 5 is also electrically connected to a control unit 6. The control unit 6 includes a data acquisition module and a control module. The data acquisition module includes a sensor assembly 611 located at the water outlet 16 for monitoring water quality and a display 612 located on the outside of the housing 1. The display 612 is signal-connected to the sensor assembly 611. The control module includes a controller A621 for adjusting the flow rate of the water pump 2, a controller B622 for adjusting the intensity of the ultraviolet lamp 41, and a controller C623 for controlling the amount of silica photocatalyst powder dispensed by the dispenser 42. Controllers A621, B622, and C623 are electrically connected to the display 612. The sensor assembly 611 in the data acquisition module detects the water quality in real time, determining the quality of the water treated by the solar water treatment system. Whether the water quality after treatment by the device meets the usage requirements, when the water turbidity is ≤1 NTU, pH value is 6.5 < 8.5 and microbial content is ≤100 CFU / mL, the water quality meets the standards and can be discharged into the storage tank through the outlet 16; otherwise, the water quality does not meet the standards. The sensor component 611 of the data acquisition module transmits signals to the display 612, and the display 612 sends instructions to the controllers A621, B622 and C623 to regulate the flow rate of the water pump 2, the intensity of the ultraviolet lamp 41 and the amount of silica photocatalyst powder, so as to adjust the water treatment mode according to different water quality conditions. This makes the solar water treatment device suitable for remote areas or environments lacking power supply, and can dynamically adjust the treatment method according to the water quality to achieve efficient treatment.

[0021] To ensure that the water treated by the solar water treatment device meets the usage conditions, the sensor assembly 611 includes a sensor A6111 for detecting water turbidity, a sensor B6112 for detecting water pH, and a sensor C6113 for detecting water microbial content.

[0022] The aforementioned sensor A6111 is a turbidity sensor used to detect the turbidity of the water; sensor B6112 is a pH sensor used to detect the pH of the water; and sensor C6113 is a microbial sensor used to detect the microbial content in the water. When the water turbidity is ≤1 NTU, pH is 6.5 < 8.5, and the microbial content is ≤100 CFU / mL, the water quality meets the standards and can be discharged into the storage tank through outlet 16. When the water quality does not meet the standards, such as when the turbidity is >1 NTU, sensor A6111 will transmit a signal to the display. Device 612 sends commands to controller A621 via display 612. Controller A621 accelerates the water supply of pump 2, i.e., increases the water flow rate. When pH < 6.5 or pH > 8.5, and microorganisms > 100 CFU / mL, sensors B6112 and C6113 transmit signals to display 612. Display 612 then sends commands to controllers B622 and C623. Controller B622 adjusts the intensity of ultraviolet lamp 41, and controller C623 adjusts the amount of silica photocatalyst powder dispensed by dispenser 42. A UV254 sensor can also be added to detect the concentration of organic matter in the water. When the concentration of organic matter in the water is > 2abs / cm, the amount of silica photocatalyst powder dispensed is increased. A flow sensor can also be added to detect the water flow rate and dynamically adjust the frequency of silica photocatalyst powder dispensing, such as dispensing 0.05g of silica photocatalyst powder per second at a flow rate of 3L / min.

[0023] To ensure that the solar photovoltaic panel 51 always faces the sun, maximizes solar energy absorption, and improves power generation efficiency, such as Figure 2 As shown, the photovoltaic panel assembly 5 also includes a light-tracking system. The light-tracking system includes a wheel 53 fixed to the bottom of the support 51, a control main board 54 mounted on the side wall of the support 51, and a solar radiation sensor 55 mounted on the top of the housing 1. The wheel 53 is rotatably mounted on the top of the housing 1 to drive the support 51 to rotate. The solar radiation sensor 55 is electrically connected to the control main board 54, and the control main board 54 is electrically connected to the wheel 53 to control its rotation. The solar radiation sensor 55 receives the sunlight intensity and feeds the signal back to the control main board 54, which then drives the wheel 53 to rotate, thereby causing the solar photovoltaic panel 51 to rotate according to the sun's position, ensuring that the solar photovoltaic panel 51 always faces the sun. Specifically, the solar radiation sensor 55 is located at the center of the back of the solar photovoltaic panel 51 and is used to monitor the sunlight intensity received by the photovoltaic panel in real time, ensuring that the photovoltaic panel is at the optimal angle to maximize solar energy absorption. When the light intensity is <200W / m², the system can be adjusted accordingly. 2A power-saving mode is triggered at certain times. As a preferred embodiment, the aforementioned solar tracking system also includes photosensors located at the four corners of the solar photovoltaic panel 51. These sensors are electrically connected to the control motherboard 54. The solar azimuth / altitude angle deviation is calculated with an accuracy of ±0.5° by comparing the X / Y axes of the four light intensity signals. Specifically, the connection between the solar tracking system and the solar photovoltaic panel 51 employs both mechanical transmission and electrical connection. Specifically, a stepper motor is connected to the drive shaft via a reduction gearbox with a reduction ratio of 1:10. The drive shaft is fixed to the photovoltaic panel bracket 51 using flange bolts. The control motherboard 54 outputs a PWM signal to control the motor speed, with a specific adjustment range of 0-50 rpm, thereby controlling the rotation angle of the solar photovoltaic panel 51. This allows the solar water treatment device to automatically adjust the angle of the solar photovoltaic panel 51 according to changes in the sun's position, reducing manual intervention and saving energy consumption. In addition, the automatic tracking system of the solar photovoltaic panel 51 has a compact structure, is easy to install and maintain, and is particularly suitable for use in remote areas or environments lacking power supply. The power generation efficiency of the solar photovoltaic panel 51 with tracking system is 20%-30% higher than that of the fixed solar photovoltaic panel 51, and it can still provide stable power supply in low light environments.

[0024] To further ensure the filtration effect of filter unit 3 and effectively remove impurities in the water, the filter layer 31 is made of polypropylene fiber, the carbon fiber layer 32 is made of activated carbon fiber, and the ultrafiltration membrane layer 33 is made of polyethersulfone ultrafiltration membrane. Filter layer 31, made of polypropylene fiber material, has a filtration accuracy of 50 micrometers and is used to remove larger particles. Compared to traditional single-layer filters, polypropylene fiber has higher mechanical strength and corrosion resistance, and a longer service life. The carbon fiber layer 32 uses activated carbon fiber with a high specific surface area to adsorb odors, organic pollutants, and some heavy metal ions in the water. Compared to ordinary activated carbon, activated carbon fiber has a larger adsorption capacity and a faster adsorption rate. The ultrafiltration membrane layer 33 uses a polyethersulfone (PES) ultrafiltration membrane with a filtration accuracy of 0.01 micrometers and is used to remove bacteria, viruses, and small suspended solids. Compared to traditional microfiltration membranes, ultrafiltration membranes have higher filtration accuracy and a longer service life.

[0025] To ensure the normal operation of the battery assembly 52, and to save space in the entire solar water treatment unit, such as Figure 1 , Figure 2 As shown, the battery assembly 52 is disposed inside the housing 1, and a battery protection box 521 is provided on the outside of the battery assembly 52. ​​By providing the battery protection box 521, the battery assembly 52 is separated from the liquid, preventing the liquid from seeping into the battery assembly 52 and ensuring the safe operation of the battery assembly 52.

[0026] When the volume of water to be processed is small, pump 2 is used to pump water, but it consumes a lot of electricity. To solve this problem, such as... Figure 1 As shown, the top of the housing 1 is also provided with a second water inlet 15, which is connected to the filter layer 31 through a pipe 14. By directly opening the second water inlet 15 on the top of the housing 1 and connecting the second water inlet 15 to the filter layer 31 through the pipe 14, the operator can directly pour water in from the second water inlet 15, saving power consumption.

[0027] To prevent substandard water from flowing into the storage tank through outlet 16, such as Figure 1 As shown, the solar water treatment device also includes a reflux control unit 7, which includes a three-way solenoid valve 71. The inlet of the three-way solenoid valve 71 is connected to the outlet 16. The first outlet of the three-way solenoid valve 71 is connected to a reflux solenoid valve 72 for controlling the reflux of substandard water. A reflux pipe 722 is connected to the reflux solenoid valve 722, and a reflux pump 721 is installed on the reflux pipe 722. The other end of the reflux pipe 722 is connected to the filter unit 3. The second outlet of the three-way solenoid valve 71 is connected to an outlet solenoid valve 73 for controlling the discharge of compliant water. An outlet pipe 731 is connected to the outlet solenoid valve 73. The reflux solenoid valve 72 and the outlet solenoid valve 73 are electrically connected to a controller D74, which is electrically connected to a display 612. The water quality is monitored by a data acquisition module located at the outlet 16. The data acquisition module for water quality monitoring includes sensors A6111, B6112, and C6113. It monitors key parameters of the treated water in real time. When any sensor detects a value exceeding the safe range, such as turbidity > 1 NTU, microorganisms > 100 CFU / mL, or pH < 6.5 or pH > 8.5, the sensor sends a signal to the display 612. The display 612 then sends a command to the controller D74, which closes the outlet solenoid valve 73 and opens the return solenoid valve 72 and return pump 721. The water flows back into the housing 1 and is further treated by the filtration unit 3 and disinfection unit 4 until the water quality meets the standards. Then, the sensor sends a signal back to the display 612, which in turn sends a command to the controller D74. The controller D74 closes the return solenoid valve 72 and return pump 721 and opens the outlet solenoid valve 73, allowing the water to flow into the storage tank for use.
