Description

Technical Field

[0001] The patent of this invention relates to the technical field of garden landscape water purification and intelligent environmental protection equipment, specifically to a water purification device that integrates photocatalytic degradation, intelligent control, interactive system and landscape aesthetic design. Background Art

[0002] Landscape water bodies are an important part of urban ecosystems, but they are susceptible to the intrusion of surface runoff pollutants (such as nitrogen, phosphorus, organic impurities, and microorganisms), leading to eutrophication, algae growth, and water quality deterioration. Traditional purification technologies have the following limitations: Physical / biological methods are inefficient: sand filtration and artificial wetlands require large areas, have long treatment cycles, and are difficult to degrade insoluble organic pollutants; conventional photocatalytic technology has poor applicability: existing photocatalytic water purification equipment mostly uses fixed reactors or nanopowder catalysts, which have strong dependence on ultraviolet light sources, easy catalyst loss, and poor compatibility with landscapes; lack of intelligence: the lack of an adaptive control system that integrates water quality, light, and water flow, making it impossible to dynamically adjust parameters such as light intensity and hydraulic retention time according to pollutant concentrations.

[0003] In response to the above problems, the present invention proposes an intelligent interactive garden landscape piezoelectric photocatalytic water purification device, the innovation of which lies in the integrated circulation system design of "solar energy supply - intelligent regulation - collaborative purification - ecological reuse": a bionic structure (rock shape) is used to build in a photocatalytic module to achieve the unity of efficient degradation and landscape aesthetics; a wide-spectrum responsive catalytic particle material is selected to convert light energy into electrical energy through solar cell components, driving LED light sources to activate the electronic transition of piezoelectric photocatalytic materials, reducing external energy supply requirements; the interactive system monitors the environment and interacts with users in real time through infrared sensing; the intelligent controller dynamically adjusts the light source intensity, aeration frequency and water circulation to ensure purification efficiency; after multi-stage filtration and photocatalytic degradation, the sewage is secondary purified by the ecological components and reused for greening irrigation, ultimately achieving the goal of water resource regeneration and technological ecological integration. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a landscape water treatment device with piezoelectric-photocatalytic synergistic efficiency and intelligent regulation. It enhances the photocatalytic activity by stimulating the piezoelectric effect through mechanical stress, and combines multi-stage filtration and aeration optimization to achieve efficient and energy-saving water purification.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] This invention provides an intelligent interactive landscape piezoelectric photocatalytic water purification device. This device, centered around a photocatalytic reaction wall, integrates solar cell modules, an ecologically designed ornamental pond, an intelligent control system, and an interactive system to achieve wastewater purification and ecological recycling. Residential sewage is pumped into a water storage tank via a sewage pipe connected to a control box. After pretreatment through a filter screen, it enters a reaction tank. Piezoelectric photocatalytic particles within the tank activate the photocatalytic reaction under the illumination of a solar-powered LED light array. Simultaneously, a bottom aeration head array supplies oxygen through aeration tubes using a micro-air pump. Combined with the mechanical energy of the water flow, this stimulates the piezoelectric effect, resulting in a "light-electricity-gas" synergistic degradation of pollutants. The intelligent control system includes a water quality sensor module, a soil sensor, an intelligent controller, and a control box, which dynamically adjusts the photocatalytic intensity, aeration frequency, and water circulation path. Purified water flows through a drainage trough with a built-in ceramic filter for secondary filtration before flowing vertically into the ecological pond, where it is guided through seepage pipes to the root systems of green plants.

[0007] The interactive system includes a translucent LED matrix on the wall, an infrared sensor array, a backend management system, and a pressure-sensitive power-generating floor. A data visualization engine transforms water quality parameters into dynamic display effects. Pressure-sensitive power-generating flooring is laid around the pool. When users step on it, the piezoelectric effect converts electricity into power, which in real time powers the light strips and screen projections on the translucent LED matrix. The higher the frequency of stepping, the more pronounced the dynamic effects of the translucent LED matrix. The translucent LED matrix displays the "current power generation" and "tons of water saved from cumulative power generation" in real time, visualizing the purification process. Simultaneously, the screen interface displays "pedaling energy visualization," generating virtual water ripples as users step on them. Energy values ​​can be "fed" to virtual water droplets to unlock educational animations.

[0008] Furthermore, the LED light strips embedded in the pressure-sensing power generation floor 25 will light up the water flow trajectory as the footsteps move, forming a ground-wall linkage with the water flow light strips on the wall, simulating the visual narrative of "footsteps driving water circulation".

[0009] Furthermore, when the user approaches the wall 20, the camera recognizes actions such as waving and pointing, and automatically starts the screen effect - virtual water droplets "splash" from the stepping point on the floor to the wall. The purification data can be viewed by clicking the virtual button through gesture control.

[0010] Furthermore, during the day, the solar cell assembly 17 charges the battery pack 19 , and at night the battery pack provides electricity to the LED light source 5 , providing a light source for the piezoelectric photocatalytic particles.

[0011] Furthermore, the piezoelectric photocatalytic particles 7 are of a core-shell structure, the core can be made of piezoelectric materials such as strontium titanate, and the shell can be made of photocatalytic materials such as zinc ferrite.

[0012] Furthermore, the LED lamp array 4 is composed of dual-band lamp tubes with wavelengths of 365nm and 420nm arranged alternately.

[0013] Furthermore, the purification process of the photocatalytic reaction wall 2 is based on the "light-electricity-gas" synergistic mechanism, specifically including: the LED light array 5 activates the piezoelectric photocatalytic particles 7 to generate photogenerated electron-hole pairs, generating hydroxyl radicals to degrade pollutants; the mechanical energy of the water flow drives the deformation of the piezoelectric material to generate an auxiliary electric field, accelerating the efficiency of the photocatalytic reaction; the aeration head array 26 supplies oxygen to the bottom of the reaction tank 12 through the micro air pump 15 to enhance the oxidation reaction.

[0014] Furthermore, the control method of the intelligent control system includes: the water quality sensor module 16 monitors the COD and pH parameters of the reaction tank 12 in real time and feeds back to the intelligent controller 18; the intelligent controller 18 dynamically adjusts the light intensity of the LED light array 5, the aeration frequency of the micro air pump 15 and the pumping rate of the water pump 8 according to the water quality data; the soil sensor 22 monitors the humidity of the green wall of the ecological ornamental pool 1, and links the LED matrix 20 to display the ecological index.

[0015] Furthermore, the device uses recycled materials to construct the ecological ornamental pool 1 and the photocatalytic reaction wall 2 shell, and realizes zero external power supply for the entire system through solar cell components 17 and maintenance-free colloidal batteries 19.

[0016] Furthermore, the sewage is transported to the water storage tank 10 through the pump 8, and enters the reaction tank 12 after pre-treatment through the filter screen 11; the piezoelectric photocatalytic particles 7 are driven by the LED light source to activate the photocatalytic reaction, and the piezoelectric effect generated by the aeration oxygen supply and the mechanical energy of the water flow is combined to synergistically degrade pollutants; the purified water flows into the ecological ornamental water pool 1 after secondary filtration through the ceramic filter element 14, and the humidity of the green wall is monitored by the soil sensor 22 and the reuse path is regulated; the intelligent controller 18 optimizes the photocatalytic intensity and aeration frequency based on water quality data, and realizes public interaction through the LED matrix 20 and the AR interface.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0020] The working principle of this patented invention is based on a "light-electricity-gas" synergistic purification mechanism and intelligent energy regulation: solar cell modules convert light energy into electrical energy, driving LED light sources to activate electronic transitions in piezoelectric photocatalytic materials, generating hydroxyl radicals that efficiently degrade pollutants. Simultaneously, the mechanical energy of the water flow stimulates the piezoelectric effect to form an auxiliary electric field, and the oxygen supply from the aeration system is superimposed to enhance the oxidation reaction, achieving multi-path synergistic decomposition of pollutants. The interactive system monitors the environment and interacts with users in real time through infrared sensing. The intelligent controller dynamically adjusts the light source intensity, aeration frequency, and water circulation to ensure purification efficiency. After multi-stage filtration and photocatalytic degradation, the sewage is purified again by ecological components and reused for green irrigation, forming an integrated circulation system of "solar energy supply - intelligent regulation - synergistic purification - ecological reuse", ultimately achieving the goal of integrating water resource regeneration with scientific and technological ecology.

[0021] refer to Figure 1 The present invention provides an intelligent interactive landscape piezoelectric photocatalytic water purification device. Centered around an ecologically ornamental water pond 1, the device integrates a solar cell module 17, a photocatalytic reaction wall 2, an intelligent control system 18, and an interactive system to achieve wastewater purification and ecological recycling. The sewage inlet pipe 24, connected to a control box 3, is pumped into a water storage tank 10 by a pump 8. The sewage is pre-treated by a filter screen 11 before entering a reaction tank 12. Piezoelectric photocatalytic particles 7 within the tank activate the photocatalytic reaction under the illumination of a solar-powered LED array 5. Simultaneously, a bottom aeration head array 26 supplies oxygen through aeration tubes 6 via a micro-air pump 15. Combined with the mechanical energy of the water flow, the piezoelectric effect is stimulated, resulting in a "light-electricity-gas" synergistic degradation of pollutants. The purified water flows through a drainage trough 13 with a built-in ceramic filter element 14 for secondary filtration before flowing vertically into the ecologically ornamental water pond 1. A soil sensor 22 monitors humidity in real time and interacts with a translucent LED wall 20 to display an ecological index.

[0022] The interactive system uses an infrared sensor array 21 to capture user gestures, triggering a translucent wall-mounted LED matrix 20 to display water quality data. The water quality sensor module 16 converts parameters like COD and pH into dynamic particle effects via an intelligent controller 18, projecting them onto the translucent wall-mounted LED matrix 20, creating visual feedback such as blue water quality. Pressure-sensitive power generation flooring 25 is installed around the pool. When users step on it, the piezoelectric effect converts electricity into power, which powers the light strips and screen projections on the translucent wall-mounted LED matrix 20 in real time. The higher the frequency of stepping, the more pronounced the dynamic effects on the translucent wall-mounted LED matrix 20. The translucent wall-mounted LED matrix 20 displays "current power generation" and "accumulated tons of water saved from power generation" in real time, visualizing the purification process. The entire system is powered by solar energy 17 and the pressure-sensitive power generation flooring 25, which stores energy in maintenance-free colloidal batteries 19. Combined with an ecologically designed, ornamental pool 1 constructed from recycled materials and a greening reuse pipeline connected to the outlet pipe 23, the system ultimately achieves a technologically integrated cycle of wastewater purification, landscape creation, and public education.
