Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a solar-powered water purification device. Background Technology

[0002] When water is supplied for use, there are often many impurities on its surface. If it is directly transported and used, it may cause many unnecessary problems. It needs to be monitored and purified before it can be used normally. Therefore, a water quality monitoring and purification device is needed.

[0003] An existing water quality monitoring and purification device (announcement number: CN219764725U) has at least the following drawbacks: When the filter screen becomes clogged during use, it is necessary to manually disassemble and clean the filter screen. At the same time, when the activated carbon filter screen becomes saturated or aged after long-term use, although the water quality tester can detect it in time, the detected water is difficult to recirculate and process, resulting in the water being discharged after the activated carbon filter screen is replaced, which causes a waste of resources. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solar-powered water purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solar-powered water purification device includes a water purification tank. A solar panel is mounted on the top surface of the water purification tank, and a battery is fixed to the rear side of the tank. An MPPT controller is electrically connected between the solar panel and the battery. The water purification tank contains a purification assembly, including a fine-mesh filter and an activated carbon filter slidably disposed inside the tank, with the fine-mesh filter positioned above the activated carbon filter. A water quality monitor is fixed through the front side of the water purification tank. A first solenoid valve is fixedly connected to the left side of the tank near the bottom, and a second solenoid valve is fixedly connected to the top surface of the tank. A water inlet pipe is fixedly connected to the top surface of the second solenoid valve. An electromagnetic flow valve is fixedly connected to one side of the first solenoid valve. A water pump is installed on the front side of the water purification tank, and a flat nozzle is located below the fine-mesh filter.

[0007] As a further embodiment of this utility model, the rear end of the fine-pore filter screen is inclined downwards, a lead screw is rotatably connected inside the water purification tank, a drive motor is fixed to the front side of the water purification tank, the output shaft of the drive motor is fixed to the front end of the lead screw, the flat nozzle is threadedly connected to the outer wall of the lead screw, the top surface of the flat nozzle abuts against the bottom surface of the fine-pore filter screen, the water pump's suction pipe is connected and fixed to the front side of the water purification tank near the bottom surface, the water pump's delivery pipe passes through the front side of the water purification tank and is connected and fixed to the flat nozzle, and a sewage discharge box is installed at the rear side of the water purification tank corresponding to the position of the fine-pore filter screen, and a sealing cover is detachably installed on the bottom surface of the sewage discharge box.

[0008] As a further embodiment of this utility model, an electric push rod is fixed to the rear side of the water purification tank, and a baffle is fixed to one end of the telescopic rod of the electric push rod. The baffle is slidably set to the top surface of the sewage tank.

[0009] As a further embodiment of this utility model, both the fine-pore filter screen and the activated carbon filter screen are fixed with mounting plates on their left sides, and the mounting plates are detachably installed on the left side of the water purification tank by bolts.

[0010] As a further embodiment of this utility model, a limiting rod is fixed inside the water purification tank, the flat nozzle is slidably disposed on the outer wall of the limiting rod, and positioning blocks are fixed on the inner wall of the water purification tank at the top and bottom right sides of the fine pore filter and the activated carbon filter.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a water quality monitor and an electromagnetic flow valve, the purified water can be monitored in real time. When the electromagnetic flow valve detects that the outflow rate has reached the set value, the first and second electromagnetic valves close simultaneously, leaving the water inside the water purification tank. The water is then pumped out of the tank and sprayed through a flat nozzle onto the fine-mesh filter to clean it. This allows the impurities clogging the filter to be discharged into the wastewater tank, achieving rapid cleaning of the filter and ensuring the normal operation of the water purification process. If the water quality monitor detects that the water quality is substandard, the activated carbon filter is replaced after the water is left in the tank. The water is then pumped back to the activated carbon filter for further purification until the water meets the required quality standards before being discharged, thus avoiding water waste.

[0022] like Figures 1-4 As shown, a solar-powered water purification device includes a water purification tank 1. A solar panel 101 is mounted on the top surface of the water purification tank 1, and a battery 102 is fixed to the rear side of the water purification tank 1. An MPPT controller is electrically connected between the solar panel 101 and the battery 102. A purification assembly is installed inside the water purification tank 1, including a fine-pore filter 2 and an activated carbon filter 201 slidably disposed inside the water purification tank 1. The fine-pore filter 2 is located within the activated carbon filter 201. Above the carbon filter 201, a water quality monitor 202 is fixedly installed through the front side of the water purification tank 1. A first solenoid valve 203 is fixedly connected to the left side of the water purification tank 1 near the bottom. A second solenoid valve 204 is fixedly connected to the top surface of the water purification tank 1. A water inlet pipe is fixedly connected to the top surface of the second solenoid valve 204. An electromagnetic flow valve 205 is fixedly connected to one side of the first solenoid valve 203. A water pump 206 is installed on the front side of the water purification tank 1. A flat nozzle 207 is installed below the fine mesh filter 2.

[0023] like Figures 2-4As shown, in this embodiment, the rear end of the fine-mesh filter 2 is inclined downwards. A lead screw 3 is rotatably connected inside the water purification tank 1. A drive motor 301 is fixed to the front side of the water purification tank 1. The output shaft of the drive motor 301 is fixed to the front end of the lead screw 3. A flat nozzle 207 is threadedly connected to the outer wall of the lead screw 3. The top surface of the flat nozzle 207 abuts against the bottom surface of the fine-mesh filter 2. The water pump 206's pumping pipe is fixedly connected to the front side of the water purification tank 1 near the bottom surface. The water pump 206's delivery pipe passes through the front side of the water purification tank 1 and is fixedly connected to the flat nozzle 207. A drain tank 302 is installed on the rear side of the water purification tank 1, corresponding to the position of the fine-mesh filter 2. A sealing cover is detachably installed on the bottom of the drain tank 302. By opening the first solenoid valve 203 and the second solenoid valve 204, water is discharged from the inlet pipe into the water purification tank 1. The water is then filtered and purified through the fine-mesh filter 2 and the activated carbon filter 201 before being discharged through the second solenoid valve 204. During this process, the water quality monitor 202 and the solenoid flow valve 205 monitor the water flow and quality in real time. When the solenoid flow valve 205 detects that the outflow rate has reached the set value, the first solenoid valve 203 and the second solenoid valve 204... The second solenoid valve 204 is simultaneously closed, allowing water to remain inside the water purification tank 1. Then, the water pump 206 is activated to draw water from the water purification tank 1 and spray it through the flat nozzle 207 onto the fine-mesh filter 2. The flat nozzle 207 moves along the bottom surface of the fine-mesh filter 2, causing impurities clogging the filter 2 to be flushed out by the water sprayed from the flat nozzle 207. This water then flows through the inclined surface of the fine-mesh filter 2 into the drain tank 302, achieving rapid cleaning of the fine-mesh filter 2 and ensuring the normal operation of the water purification process. Afterwards, the first solenoid valve 203 and the second solenoid valve 204 can be opened. The second solenoid valve 204 continues the water purification operation. When the water quality monitor 202 detects that the water quality is unqualified, the first solenoid valve 203 and the second solenoid valve 204 are closed simultaneously, allowing the water to remain inside the water purification tank 1. Then, the activated carbon filter 201 is removed and replaced. The water remaining inside the water purification tank 1 can then be drawn out and moved back above the activated carbon filter 201 for re-purification until the water quality monitor 202 detects that the water quality is qualified. After that, the first solenoid valve 203 and the second solenoid valve 204 can be opened to continue the water purification operation, thus avoiding the waste of water resources.

[0024] like Figures 2-4 As shown in this embodiment, an electric push rod 4 is fixed to the rear side of the water purification tank 1. A baffle 401 is fixed to one end of the telescopic rod of the electric push rod 4. The baffle 401 is slidably set to the top surface of the sewage tank 302. The opening and closing of the baffle 401 can be controlled by the electric push rod 4. The baffle 401 can be opened when cleaning the fine pore filter screen 2 and closed when purifying water to prevent water from being discharged from the water purification tank 1.

[0025] like Figures 2-4As shown in this embodiment, both the fine pore filter 2 and the activated carbon filter 201 are fixed with mounting plates 5 on their left sides. The mounting plates 5 are detachably installed on the left side of the water purification tank 1 by bolts. By setting the mounting plates 5 to be detachably installed on the water purification tank 1 by bolts, it is convenient to disassemble and replace the fine pore filter 2 and the activated carbon filter 201.

[0026] like Figures 2-4 As shown in this embodiment, a limiting rod 6 is fixed inside the water purification tank 1, and the flat nozzle 207 is slidably disposed on the outer wall of the limiting rod 6. Positioning blocks 601 are fixed on the inner wall of the water purification tank 1 at the top and bottom right sides of the fine pore filter 2 and the activated carbon filter 201. The limiting rod 6 can limit the movement of the flat nozzle 207, and the positioning blocks 601 can position the fine pore filter 2 and the activated carbon filter 201 during installation.

[0027] like Figures 2-4 As shown in this embodiment, a PLC controller is fixed to the front of the water purification tank 1. The battery 102, water quality monitor 202, first solenoid valve 203, second solenoid valve 204, solenoid flow valve 205, water pump 206, drive motor 301, and electric push rod 4 are all electrically connected to the PLC controller. By setting the PLC controller, it is convenient to read the values ​​of the water quality monitor 202 and the solenoid flow valve 205 in real time and automatically open and close the first solenoid valve 203, the second solenoid valve 204, the water pump 206, the drive motor 301, and the electric push rod 4.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when purifying water, by opening the first solenoid valve 203 and the second solenoid valve 204, water is discharged from the inlet pipe into the water purification tank 1. The water is then filtered and purified through the fine-mesh filter 2 and the activated carbon filter 201 before being discharged from the second solenoid valve 204. During this process, the water quality monitor 202 and the solenoid flow valve 205 monitor the water flow and water quality in real time. When the solenoid flow valve 205 detects that the outflow rate reaches the set value, the PLC controller reads the signal from the solenoid flow valve 205, causing the first solenoid valve 203 and the second solenoid valve 204 to close simultaneously, leaving the water inside the water purification tank 1. Then, the water pump 206 is started to draw the water remaining inside the water purification tank 1 and sprays it onto the fine-mesh filter 2 through the flat nozzle 207. At this time, the drive motor 301 is started to rotate the lead screw 3. The flat nozzle 207 and the lead screw 3 are connected by a thread on their outer wall. The flat nozzle 207 moves to the bottom of the fine pore filter 2. At this time, the electric push rod 4 is activated to open the baffle 401. Then, the impurities blocked on the fine pore filter 2 are flushed out by the water sprayed from the flat nozzle 207 and flow into the sewage tank 302 through the inclined surface of the fine pore filter 2, realizing the rapid cleaning of the fine pore filter 2 and ensuring the normal operation of water purification. Then, the first solenoid valve 203 and the second solenoid valve 204 can be opened to continue the water purification operation. When the water quality monitor 202 detects that the water quality is not up to standard, the first solenoid valve 203 and the second solenoid valve 204 are closed at the same time, so that the water is left inside the water purification tank 1. Then, the mounting plate 5 and the activated carbon filter 201 are removed and replaced. Then, the water left inside the water purification tank 1 can be drawn out and moved back above the activated carbon filter 201 for re-purification until the water quality monitor 202 detects that the water quality is up to standard. Then, the first solenoid valve 203 and the second solenoid valve 204 can be opened to continue the water purification operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
