Description

Technical Field

[0001] This utility model belongs to the field of water resource reuse technology, specifically, it relates to an integrated device for inverted umbrella-shaped sunshade and rainwater collection and reuse. Background Technology

[0002] With the acceleration of urbanization, the contradiction between water scarcity and the demand for outdoor sunshade is becoming increasingly prominent. On the one hand, urban outdoor recreational areas (such as community squares, park trails, and school activity areas) often need to be equipped with sunshade facilities. Traditional sunshades and umbrella-shaped structures only have the function of sunshade, which is limited and does not make full use of space and natural resources.

[0003] Meanwhile, the separate deployment of traditional sunshade devices and rainwater harvesting systems not only increases construction and maintenance costs but also wastes limited outdoor space, making it difficult to meet the needs of communities, parks, campuses, and other scenarios for multifunctional and integrated facilities.

[0004] Patent document CN214282566U discloses a municipal garden water storage and irrigation system, which includes a water tank and a collection device. The water tank is located on the ground and has an opening at its upper end. The collection device includes a support rod assembly for the water tank and a collection umbrella installed at the upper end of the support rod assembly. The collection umbrella includes a ring that slides and fits onto the support rod assembly and various sets of frames. Each set of frames is covered with an umbrella surface. Several sets of drainage holes are opened at the lower end of the umbrella surface. Each set of umbrella surfaces is in the shape of an inverted umbrella. A cylinder is installed at the upper end of the support rod assembly. The cylinder includes a cylinder body and a push rod. The push rod extends vertically downward along the support rod assembly, and its lower end is fixedly connected to the ring. Green plants are planted on the ground, and a water pump with its lower end connected to the water tank is installed on the ground. A water pipe is installed at the outlet of the water pump and faces the green plants.

[0005] However, existing rainwater harvesting systems, such as those in patent document CN214282566U, mostly focus only on collection. They suffer from incomplete sediment separation, imprecise filtration and grading, and insufficient adaptability in disinfection processes. They lack the water purification capabilities of large-scale water treatment plants, resulting in collected rainwater that can only be used for the most basic water needs and cannot be used for domestic purposes. This leads to low rainwater reuse rates and difficulty in ensuring water quality. To enable the collected rainwater to be used for domestic purposes and to allow for the wider application of non-large-scale water treatment systems, this invention designs an integrated device for inverted umbrella-shaped shading and rainwater collection and reuse, thus solving the aforementioned problems.

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] like Figure 1 As shown, an integrated device for inverted umbrella-shaped sunshade and rainwater collection and reuse includes: a water collection structure 1, a sediment separation structure 2, and a filtration structure 4. The water collection structure 1 includes a water collection umbrella 11. The water collection umbrella 11 is installed above the ground, with its top edge extending upwards to form a curved water collection trough 6. A connecting opening is located at the lowest point of the water collection trough 6, and a sediment separation structure 2 is connected below this opening. The sediment separation structure 2 has a sand discharge port at its bottom and a drain outlet on its side wall. The drain outlet extends to one side and connects to a filtration structure 4. The filtration structure 4 consists of at least three interconnected water tanks, each containing a sand filter or activated carbon filter. The water tank at the end of the filtration structure 4 furthest from the sediment separation structure 2 is connected to a disinfection structure. The disinfection structure includes ultraviolet disinfection or chemical disinfection.

[0022] The working principle of this application is as follows: the large canopy of the water collection umbrella 11 provides shade and a space for people to move around. It expands the water collection area while guiding water flow. The connection point is located at the lowest point to ensure smooth water collection without residue. The sediment separation structure 2, through its zoned design of sand discharge and drainage outlets, efficiently separates sediment first, reducing the load on subsequent filtration and extending the service life of the filter media. The filtration structure 4 adopts a multi-pool staged design, combined with a sand filter and an activated carbon filter, purifying impurities and odors in the water layer by layer for a more thorough purification effect. The disinfection structure offers both ultraviolet and chemical disinfection options to adapt to different water quality needs and ensure safe effluent. It boasts the advantages of efficient water purification and rainwater reuse.

[0023] Specifically, the sediment separation structure 2 includes a cyclone sedimentation tank 21, an impeller, a stirring motor, a sand pump 22, and a sand-water separator. The cyclone sedimentation tank 21 is funnel-shaped, wider at the top and narrower at the bottom. The impeller is rotatably connected inside the cyclone sedimentation tank 21 to drive sand particles in the water to sink along the inner wall of the cyclone sedimentation tank 21. The stirring motor is fixed to the cyclone sedimentation tank 21, and its output shaft is coaxially fixed to the impeller. The sand pump 22 is connected to the sand discharge port, and a sand collection device 3 is connected to the rear end of the sand pump 22. The sand-water separator is housed in the sand collection device 3. The sand pump 22 is used to extract the sand-water mixture from the bottom of the sedimentation tank and transport it under high pressure to the sand-water separator.

[0024] The water collection structure 1 also includes a water collection pipe 12, which is fixed and connected to the connection port. The water collection pipe 12 extends downward and is fixed and connected to the vortex sedimentation tank 21. At least two guide channels 7 are provided on the surface of the water collection trough 6 along the radial direction of the water collection umbrella 11. The guide channels 7 are tilted at the same angle as the umbrella surface, so that rainwater can be collected into the rainwater collection pipe 12 under the action of gravity.

[0025] In one embodiment, the water collection pipe 12 is made of corrosion-resistant PVC pipe.

[0026] In one embodiment, the surface of the guide channel 7 is smoothed to reduce the resistance to rainwater flow and ensure that rainwater can flow into the water collection pipe 12 quickly and smoothly.

[0027] In one embodiment, rainwater is transported from the collection pipe 12 to the vortex grit chamber 21. When the water volume reaches a certain level, the sediment separation structure 2 is activated, and the vortex grit chamber 21 serves as a rainwater storage unit. The material of the vortex grit chamber 21 must have good sealing and corrosion resistance to prevent rainwater leakage and deterioration. A simple filtration device is installed at the connection between the vortex grit chamber 21 and the collection pipe 12 to initially filter out larger impurity particles in the rainwater.

[0028] The filtration structure 4 includes a first settling tank 41, a second settling tank 42, and a third settling tank 43. The drain outlet, the first settling tank 41, the second settling tank 42, and the third settling tank 43 are sequentially connected. Each settling tank is filled with filter media, with the pore size decreasing progressively. The third settling tank 43 contains at least one of a sand filter and an activated carbon filter. The sand filter uses layers of sand of different particle sizes to filter rainwater, removing suspended particles and colloids from the water. The activated carbon filter primarily adsorbs organic matter, odors, and some heavy metal ions from the water, improving the quality of the rainwater.

[0029] In one embodiment, if the rainwater is used for purposes requiring high water quality, such as domestic miscellaneous water use (car washing, toilet flushing, etc.), disinfection treatment is required. The disinfection structure includes a disinfection tank connected to the rear of the third settling tank 43. The disinfection tank is equipped with an ultraviolet disinfection device or a chemical disinfectant. Ultraviolet disinfection destroys the structure of microorganisms through ultraviolet irradiation, achieving sterilization; chemical disinfection uses disinfectants such as chlorine and chlorine dioxide to disinfect the rainwater.

[0030] A water pump 8 is installed inside the disinfection pool. The water pump 8 draws rainwater from the storage tank for non-potable purposes such as watering surrounding flowers and plants and washing the ground, thereby realizing the recycling of water resources and saving water resources.

[0031] The devices can be installed in community leisure plazas, children's playgrounds, and other locations, providing residents with shaded and cool places while collecting rainwater for watering the community's green plants, thus reducing water costs for property management. Placed along lakeside paths or near pavilions in parks, they provide shade for visitors while collecting rainwater for irrigating surrounding flowers and lawns, aligning with the park's ecological and environmentally friendly design philosophy. Installed in school playground rest areas and open-air reading corners, they create comfortable outdoor activity spaces for teachers and students, and utilize collected rainwater to maintain the campus's green landscape, serving as a valuable educational demonstration and allowing students to directly experience the practical application of water resource recycling.
