Description

Technical Field

[0001] The utility model relates to the field of photovoltaic technology, and more specifically, particularly to a solar power generation platform for water purification on water. Background Art

[0002] Freshwater shortage has become an increasingly important issue in the context of sustainable development. The continued growth of the global population, rapid urbanization trends, over-allocation of water resources, and the impact of climate change have exacerbated the severity of freshwater shortages. Many research efforts have been devoted to developing efficient, sustainable, cost-effective, and environmentally friendly technologies to increase water supply from sources such as seawater, polluted water, and atmospheric moisture, including membrane filtration, ultraviolet irradiation, oxidation processes, ion exchange, and thermal distillation. However, these technologies are costly to implement and difficult to be widely used. Solar thermal distillation is a technology with historical origins dating back to ancient Greece that simulates the natural water cycle and heat energy transfer, converting solar radiation into heat to produce water vapor, which is then condensed to produce clean water. However, due to the limited absorption of sunlight by water, the efficiency of natural solar evaporation is very low.

[0003] At present, solar panels have great advantages in the use of solar energy. As a device that utilizes solar energy resources, solar panels have great advantages and application potential in the field of clean energy. By absorbing sunlight, the device that converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect is a promising new power source. Traditional ground solar panels require a large area of ​​land for installation and a large amount of water for cleaning and maintenance.

[0004] Therefore, it is of great significance to make full use of solar energy and combine photovoltaic technology with solar thermal distillation to meet the needs of drinking water and electricity at the same time. Utility Model Content

[0025] Please refer to Figure 1 and Figure 2 The utility model provides a solar power generation platform for water purification on water, comprising a photovoltaic cell 1, a distillation device 2 and a stabilizing platform 3 arranged in sequence from top to bottom;

[0026] The photovoltaic cell 1 includes a solar panel 11, a storage battery 12 and a power transmission line 13, and the solar panel 11 and the storage battery 12 are connected via the power transmission line 13;

[0027] The distillation device 2 includes a water treatment box 21, a fiber membrane 22, a float 23, a water outlet pipe 24 and a water inlet valve 25; the fiber membrane 22 is arranged in the water treatment box 21, and divides the interior of the water treatment box 21 into a distillation chamber 211 and a water inlet chamber 212; a water inlet 213 is arranged on the side of the water inlet chamber 212, and the water inlet valve 25 is arranged on the water inlet 213 and is used to control the opening or closing of the water inlet 213; the float 23 is arranged in the water inlet chamber 212, and a linkage rod 26 is arranged on the float 23 and connected to the water inlet valve 25 through the linkage rod 26; a water outlet is arranged on the side of the distillation chamber 211, and the water outlet pipe 24 is connected to the water outlet;

[0028] The stable platform 3 can float on the water surface and is used to support the distillation device 2 and the photovoltaic cell 1 .

[0029] In an embodiment of the utility model, the solar panel 11 is used to absorb solar energy. The generated electricity can be transmitted to the power consumption place through a long line, and can also be used to charge the battery 12 through the transmission line 13, so that the battery 12 stores energy, so that the battery 12 can provide energy for the operation of the electronic components on the entire device.

[0030] The main body of the distillation device 2 is a water treatment box 21, and the interior of the water treatment box is divided into two parts, the lower part, by a fiber membrane 22, wherein the lower part has a larger space for external environmental water to enter, and the upper part has a smaller space for storing the clean water produced by condensation after distillation. The fiber membrane 22 in this embodiment has a unique dual function, selectively allowing water vapor to pass through and preventing the penetration of liquid water, so that the clean water produced after distillation will not fall through the fiber membrane 22, and it can also prevent the lower environmental water from entering the upper distillation chamber 211.

[0031] In order to prevent the entire device from sinking due to excessive inflow of ambient water into the water inlet chamber 212, a float 23 is provided inside the water inlet chamber 212 in this embodiment, and a linkage rod 26 is provided on the float 23 to connect with the water inlet valve 25. When ambient water flows in, buoyancy is generated to lift the float 23, and the linkage rod 26 drives the water inlet valve 25 to close to stop water inflow. Conversely, when the water inside the water inlet chamber 212 evaporates to a certain amount, the float 23 falls, and the linkage rod 26 drives the water inlet valve 25 to open to allow external water to flow in.

[0032] The working process of the utility model is as follows: the whole device is placed on the water surface, lake surface or sea surface. Due to the influence of gravity, the stable platform 3 is submerged in the water surface, and water continuously flows into the water inlet chamber 212, so that the float 23 in the water inlet chamber 212 is continuously raised by buoyancy. When the water volume in the water inlet chamber 212 reaches a certain level, the float 23 completely floats up, and the linkage rod 26 drives the water inlet valve 25 to close, thereby stopping the water inlet. The upper solar panel 11 can absorb solar energy, output or store electricity in the battery 12, so that the entire water inlet chamber 212 is heated, accelerating the evaporation of water. Water vapor continuously evaporates through the limiting membrane and condenses into liquid clean water in the distillation chamber 211, and the liquid clean water cannot pass through the fiber membrane 22 and flow back to the water inlet chamber 212. When the liquid clean water accumulates to a certain amount, it flows out through the outlet pipe 24 to achieve the water purification function.

[0033] Preferably, an auxiliary heating device is also included, and the auxiliary heating device includes a heating control module and a heating film 4; the heating film 4 is arranged on the inner wall of the water inlet chamber 212, and the heating control module, the heating film 4 and the storage battery 12 form a closed loop. Through the above structural design, the heating film 4 is respectively attached to the upper part of the cavity wall around the inside of the water inlet chamber 212, which can make full use of the electricity generated by the photovoltaic cell 1 to heat the ambient water and accelerate the generation of water vapor, which can improve the user experience when water is urgently needed.

[0034] Preferably, the heating film 4 is a metal mesh transparent film made of a copper metal mesh, and the metal mesh transparent film is attached to the inner wall of the water inlet cavity 212 by gluing. In this embodiment, the metal mesh transparent film made of a copper metal mesh has the advantage of low square resistance, can quickly generate heat and heat the ambient water, and improve the distillation efficiency.

[0035] Preferably, a light sensor is provided at the light-transmitting part of the stabilizing platform 3, and the light sensor is connected to the input end of the heating control module, and the light sensor is used to detect the intensity of sunlight. In this embodiment, a light sensor is provided to detect the intensity of sunlight, and the heating control module controls the opening or closing of the heating film 4 according to the detection signal of the light sensor. Once it is cloudy, when the heat that can be conducted by the photovoltaic cell 1 is insufficient, the storage battery 12 directly conducts the heating film 4 on the four walls of the water inlet chamber 212, so that the entire water inlet chamber 212 is heated, accelerating the evaporation of water.

[0036] Preferably, the fiber membrane 22 can be provided in multiple layers, and the multiple layers of fiber membranes 22 are provided in parallel with each other. Through the above structural design, when there is a higher need for water purification, multiple layers of distillation structures can be superimposed, that is, multiple layers of fiber membranes 22 are provided to improve the efficiency of distilled water.

[0037] Preferably, the fiber membrane 22 is a Janus membrane with a double-layer composite structure, and the Janus membrane includes a hydrophilic layer and a hydrophobic layer. In this embodiment, a Janus (double-sided anisotropic) membrane is prepared based on electrospinning technology. The membrane has a unique dual function, the hydrophilic layer promotes water diffusion through capillary action driven by capillaries, selectively allows water vapor to pass through, and the hydrophobic layer can prevent liquid water from penetrating.

[0038] Preferably, a storage chamber is provided inside the stabilizing platform 3, and the storage chamber is an openable sealed structure; the storage chamber is used to install circuits and electronic components. Most of the stabilizing platform 3 is immersed in water to facilitate water flow into the chamber. At the same time, circuits or related sensors and other electronic components can be installed on the surface or inside.

[0039] Preferably, a tip-over alarm device is also included, and the tip-over alarm device includes a tip-over sensor, a single-chip microcomputer module and a warning light; the tip-over sensor and the single-chip microcomputer module are respectively arranged in the stable platform 3, and the warning light is arranged at the bottom of the stable platform 3, and the tip-over sensor, the single-chip microcomputer module and the warning light form a closed loop. By detecting the spatial movement angle of the entire device in real time, when the device tips over, the tip-over sensor can effectively detect it and send the detected signal to the single-chip microcomputer module, and the single-chip microcomputer module drives the warning light to work. Since the warning light is installed at the bottom of the stable platform 3, once the stable platform 3 tips over, the flashing light alarm issued by the warning light is easier to be detected, which helps the surrounding personnel to find abnormal conditions of the equipment in time.

[0040] Preferably, the tipping sensor is a gyroscope sensor.
