Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater recycling, in particular to a garden rainwater recycling device. Background Art
[0002] Rainwater refers to the water droplets formed by the condensation of water vapor in the atmosphere when it is cold, and then the water that falls from the clouds to the ground. This is part of the water cycle on Earth. Rainwater is a precious natural resource, and recycling rainwater can save fresh water resources. Especially in arid areas or areas with tight water resources, rainwater recycling devices can reduce the pressure on local water resources. Using rainwater to irrigate gardens can reduce dependence on municipal water supply, thereby reducing energy consumption and carbon dioxide emissions. Compared with extracting and treating tap water from water plants, using rainwater for irrigation is more energy-saving and environmentally friendly.
[0003] The existing garden rainwater recycling device uses a recycling mechanism to recycle rainwater when in use. The falling rainwater flows into the liquid collecting bucket and flows downwardly into the guide sleeve along the liquid collecting bucket. The rainwater in the guide sleeve continues to flow downwardly into the filter sleeve. When the rainwater passes through the filter screen in the filter sleeve, larger debris in the rainwater is blocked, and the blocked debris gathers at the bottom of the filter screen with a conical structure to prevent the debris from clogging the filter screen. The rainwater passing through the filter sleeve will flush the disinfection plate, and the sodium hypochlorite powder in the disinfection plate will gradually dissolve in the flushed rainwater. The sodium hypochlorite powder dissolves in the rainwater to form hypochlorous acid, which kills bacteria in the rainwater. The sterilized rainwater will pass through the adsorption plate again, and the adsorption plate will absorb smaller debris in the rainwater. The rainwater after passing through the adsorption plate will flow into the water storage tank through the connecting pipe for storage, thereby solving the problem that the existing rainwater recycling device cannot disinfect rainwater when collecting, resulting in bacteria breeding in the collected rainwater and inconvenience in reuse.
[0004] However, when using this method, the filter plate cannot be cleaned. If the filter plate is not cleaned for a long time, a large amount of impurities, dirt and microorganisms will accumulate on its surface, causing the pores of the filter plate to be blocked and the filtration efficiency to be reduced. This will affect the function of the rainwater recycling device, making it unable to effectively remove impurities and pollutants in the rainwater. Uncleaned filter plates will accumulate bacteria, algae and other microorganisms, which will degrade organic matter and produce odors, causing the quality of the stored rainwater to deteriorate. If there are harmful substances accumulated on the surface of the filter plate, pollutants in the rainwater will re-enter the system, increasing the risk of water pollution. Utility Model Content

[0025] After the hydraulic cylinder 16 is started, its output end will push the movable plate 17 to move, and the movement of the movable plate 17 will drive the filter plate 18 to move together, so that the filter plate 18 is gradually moved out of the inside of the recycling box 1. During the movement of the filter plate 18, the slider 19 slides on the outside of the slide rod 20, which plays a guiding and stabilizing role. This design not only ensures the smooth movement of the filter plate 18, but also effectively prevents the filter plate 18 from being offset or damaged during the movement. When the filter plate 18 is completely moved out of the recycling box 1, the staff can easily clean and replace the filter plate 18. After cleaning, put the filter plate 18 back to its original position.
[0026] Reference Figure 2 , Figure 3 and Figure 4 The left part of the recovery box 1 is fixedly connected to a protection box 4, the interior of the protection box 4 is fixedly connected to a motor 5, the output end of the motor 5 is fixedly connected to a rotating shaft 6, the outside of the rotating shaft 6 is fixedly connected to a disc 7, the outside of the disc 7 is fixedly connected to a stirring blade 8, the upper part of the recovery box 1 is fixedly connected to a liquid collecting bucket 2, the bottom of the recovery box 1 is fixedly connected to a water outlet pipe 9, the inner left part of the recovery box 1 is fixedly connected to a fixed cover 10, the interior of the fixed cover 10 is provided with a water outlet 11, and multiple stirring blades 8 are rotatably connected to the interior of the fixed cover 10, the inner left part of the recovery box 1 is fixedly connected to a guide plate 12, the interior of the baffle 21 is provided with a through groove, the interior of the recovery box 1 is fixedly connected to a liquid inlet pipe 13, and the outside of the liquid inlet pipe 13 is provided with a control valve 14.
[0027] The rainwater enters the fixed cover 10 inside the recovery box 1 through the liquid collecting hopper 2. The liquid collecting hopper 2 ensures that the rainwater can flow in unimpeded and avoids splashing or leakage that may occur during the inflow process. The motor 5 is started, and the motor 5 transmits power to the rotating shaft 6 through the output end, thereby driving it to rotate. As the rotating shaft 6 rotates, the disc 7 connected thereto also starts to rotate. The disc 7 allows the stirring blades 8 thereon to be evenly distributed around the disc 7. In this way, when the disc 7 rotates, the stirring blades 8 can stir the rainwater in all directions. In the process of stirring the rainwater by the stirring blades 8, the stirring blades 8 are controlled to stir the rainwater in all directions. When the control valve 14 is opened, the chemical disinfectant is accurately added to the interior of the fixed cover 10 through the liquid inlet pipe 13, so that the stirring blade 8 can evenly mix the disinfectant into the rainwater while stirring the rainwater, and the disinfected rainwater is smoothly discharged through the outlet 11. The guide plate 12 is designed with multiple grooves inside. These grooves not only increase the contact area of the rainwater, but also effectively guide the flow of rainwater, so that the rainwater is more evenly distributed on the upper part of the filter plate 18. Under the guidance of the guide plate 12, the rainwater is transported to the upper part of the filter plate 18 through the through groove, and the rainwater inside the recovery box 1 can be discharged outward through the outlet pipe 9.
[0028] Working principle: First, rainwater enters the fixed cover 10 inside the recovery box 1 through the liquid collecting hopper 2, and the motor 5 is started. The output end of the motor 5 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the disc 7 to rotate, and the rotation of the disc 7 drives the stirring blade 8 to rotate. At the same time, the control valve 14 is opened, and the chemical disinfectant is added to the inside of the fixed cover 10 through the liquid inlet pipe 13. The stirring blade 8 stirs the rainwater and the disinfectant, thereby achieving effective stirring of the rainwater and the disinfectant, increasing the contact time between the disinfectant and the microorganisms in the water, ensuring that the disinfectant is evenly distributed in the rainwater, and making the disinfection effect more thorough. The disinfected rainwater is discharged downward through the outlet 11, and a plurality of grooves are provided inside the guide plate 12. Under the action of the guide plate 12, rainwater is transported to the upper part of the filter plate 18 through the through groove for filtration. When the filter plate 18 is used, the hydraulic cylinder 16 is started, and the output end of the hydraulic cylinder 16 pushes the movable plate 17 to move. The movement of the movable plate 17 drives the filter plate 18 to move. The movement of the filter plate 18 drives the slider 19 to slide on the outside of the slide rod 20. Under the action of the slider 19, the filter plate 18 is moved out from the inside of the recovery box 1, and the rainwater inside the recovery box 1 can be discharged outward through the outlet pipe 9, thereby effectively cleaning the filter plate 18, removing impurities, sediments and dirt accumulated on the filter plate 18, ensuring that the filter plate 18 maintains a high-efficiency filtering capacity, ensuring smooth water flow, and improving water filtering and collection efficiency.
