Description

Technical Field

[0001] This utility model relates to the field of greening irrigation technology, and in particular to a water storage device for greening irrigation. Background Technology

[0002] Green space irrigation water storage refers to a technical system that uses artificial facilities to store natural precipitation or reclaimed water for green space irrigation during non-rainy seasons. It has the dual functions of water resource regulation and ecological maintenance. It collects and stores rainwater, surface runoff or reclaimed water through facilities such as reservoirs, water storage ponds, and weirs, and supplies water to green spaces as needed during dry seasons, solving the problem of mismatch between the water demand period of plants and natural precipitation.

[0003] Traditional irrigation water storage devices generally adopt open water tanks or underground cellar structures, relying on natural rainfall or artificial water replenishment, which leads to water loss. Especially in arid areas, the water storage efficiency is low. Irrigation is achieved through water pipelines and solenoid valves. Open water tanks evaporate too much water on sunny days, and underground cellars are prone to accumulating impurities, requiring manual cleaning. Moreover, water tanks exposed for a long time are prone to aging and cracking, increasing maintenance costs and reducing the overall water storage effect. Utility Model Content

[0004] In order to overcome the problems of traditional irrigation water storage devices, such as excessive water evaporation in open water tanks on sunny days, easy accumulation of impurities in underground cellars requiring manual cleaning, and the tendency of water tanks to age and crack due to long-term exposure, which increases maintenance costs, this utility model provides a water storage device for greening irrigation.

[0005] The technical solution is as follows: a water storage device for greening irrigation, including a water storage tank for storing natural precipitation, a cover plate for protecting the internal water liquid is fastened to the water storage tank, a flexible water storage component for flexibly adjusting and receiving rainwater is installed at the center of the bottom of the cover plate, and drainage pipes for conveying water flow are fixed to all four sides of the water storage tank.

[0006] Furthermore, several sets of rigid reinforcing strips are installed around the four sides of the water tank. The outer side of the rigid reinforcing strips is covered with an anti-corrosion coating. An insulated base is fixed to the bottom of the water tank, and a filter element is fixed to the center inside the water tank.

[0007] Furthermore, the filter element has several sets of filter holes arranged in a circumferential direction, a central compartment is formed in the center of the filter element, and a partition plate extending to the corner of the inner side of the water tank is installed on the outside of the filter element. A partition compartment is formed between the two sets of partition plates, and an installation sleeve is installed on the top of the partition compartment.

[0008] Furthermore, mounting bolts are fixed at all four corners of the top of the cover plate, a water flow channel is opened in the center of the cover plate, a central plate is installed in the center of the water flow channel, a base plate is fixed to the bottom of the central plate, a water flow ring plate is fixed to the outer perimeter of the base plate, and several sets of mounting slots are opened circumferentially on the water flow ring plate, an extension frame is formed between two sets of mounting slots, and a filter plate is installed inside the mounting slot.

[0009] Furthermore, a rotating disk is installed at the center of the central disk, a rotator is installed at the center of the rotating disk, a lithium battery pack is connected to the center of the rotator, and several sets of brush holders are fixedly connected to the outer end of the rotating disk in a circumferential manner. Several sets of mounting holes are linearly opened on the brush holders. The lithium battery pack drives the rotating disk to rotate the brush holders.

[0010] Furthermore, several sets of inclined spray plates are distributed and installed on the central plate. A pressure pump is installed at the center of the spray plate. A control battery pack is connected to the center of the pressure pump. A DC motor and a frequency converter are provided between the control battery pack and the pressure pump. Several sets of spray holes are distributed on the spray plate. An ejector is installed inside the spray hole. A water lifting pipe is connected to the bottom of the pressure pump.

[0011] Furthermore, the flexible water storage component includes a flexible inner tank layer, on which several sets of flexible skeletons are circumferentially separated. A pressure sensing ball is connected to the outer end of the flexible skeleton, and a pressure sensor is installed inside the pressure sensing ball. Several sets of water flow channels are circumferentially opened on the inner side of the flexible inner tank layer, and the inner side of the water flow channels is coated with a waterproof coating. A push rod is connected to the outer end of the pressure sensing ball, and a hydraulic cylinder is connected to one end of the push rod. A fixing plate that is fixed to the cover plate is snapped into the bottom of the hydraulic cylinder. The hydraulic cylinder drives the push rod to cause the flexible inner tank layer to open and close.

[0012] Furthermore, a sealing ring is connected between the drain pipe and the water storage tank, and a valve module is installed on the drain pipe.

[0013] The beneficial effects are: This utility model forms a double-layer protective structure through the cover plate and the flexible water storage component.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 - Figure 5 As shown, the water storage device for greening irrigation includes a water storage tank 1 for storing natural precipitation. A cover plate 2 for protecting the internal water is fastened to the water storage tank 1. A flexible water storage component 3 for flexibly adjusting and receiving rainwater is installed at the bottom center of the cover plate 2. Drainage pipes 4 for conveying water flow are fixed to all four sides of the water storage tank 1.

[0023] Please see Figure 2 - Figure 4 In this embodiment, several sets of rigid reinforcing strips 101 are distributed and installed on all four sides of the water storage tank 1. The outer side of the rigid reinforcing strips 101 is covered with an anti-corrosion coating. A heat-insulating base 102 is fixed to the bottom of the water storage tank 1. A filter element 103 is fixed to the center inside the water storage tank 1. Several sets of filter holes 104 are circumferentially opened on the filter element 103 (the filter element 103 is sintered stainless steel 316L (pore diameter 0.5mm) and is detachable, with a titanium dioxide photocatalytic coating on the surface for antibacterial purposes). A central chamber 107 is opened in the center of the filter element 103. A partition plate extending to the corner of the inner side of the water storage tank 1 is installed on the outer side of the filter element 103. A partition chamber 105 is formed between two sets of partition plates. An installation sleeve 106 is installed on the top of the partition chamber 105.

[0024] Please see Figure 3 - Figure 4 In this embodiment, mounting bolts 201 are fixedly connected to all four corners of the top of the cover plate 2. A water flow channel 302 is opened in the center of the cover plate 2. A central plate 202 is installed in the center of the water flow channel 302. A base plate 206 is fixedly connected to the bottom of the central plate 202. A water flow ring plate 203 is fixedly connected to the periphery of the base plate 206. Several sets of mounting grooves 204 are circumferentially opened on the water flow ring plate 203. An extension frame 207 is formed between two sets of mounting grooves 204. A water filter plate 205 is provided inside the mounting groove 204. A rotating disk 215 is installed in the center of the central plate 202. A rotator is installed in the center of the rotating disk 215. (Rotator encoder Omron E6B2-CWZ6C2000P / R) The rotation angle of the brush holder 213 is precisely controlled (error < 0.5°). A lithium battery pack 212 is connected to the center of the rotator. Several sets of brush holders 213 are fixedly connected to the outer end of the rotating disk 215. Several sets of mounting holes 214 are linearly opened on the brush holders 213. The lithium battery pack 212 drives the rotator to start running and drive the brush holders 213 inside the rotating disk 215 to rotate.

[0025] Please see Figure 4 - Figure 5 In this embodiment, several sets of inclined spray plates 208 are distributed and installed on the central disk 202. A pressure pump 210 is installed at the center of the spray plate 208. A control battery pack is connected to the center of the pressure pump 210. A DC motor and a frequency converter are provided between the control battery pack and the pressure pump 210. Several sets of spray holes 211 are distributed on the spray plate 208. An ejector is provided inside the spray hole 211. A water lifting pipe 209 is connected to the bottom of the pressure pump 210. The flexible water storage component 3 includes a flexible inner layer 308 (EPDM rubber + polyester reinforcement layer, 2mm thickness, weather resistance temperature -40℃~120℃). Several sets of flexible skeletons 301 are circumferentially separated on the flexible inner layer 308. A pressure sensing ball 304 is connected to the outer end of the flexible skeleton 301. A pressure sensor (Honeywell) is provided inside the pressure sensing ball 304. The 26PC series pressure sensor features silicone encapsulation, IP68 waterproof rating, and a range of 0-10 kPa. Several sets of water channels 302 are circumferentially formed on the inner side of the flexible inner layer 308. A waterproof coating 303 is applied to the inner side of each water channel 302. A push rod 305 is connected to the outer end of the pressure sensing ball 304. One end of the push rod 305 is connected to a hydraulic cylinder 307. A fixing plate 306, which is fixed to the cover plate 2, is snapped into the bottom of the hydraulic cylinder 307. The hydraulic cylinder 307 drives the push rod 305 to open and close the flexible inner layer 308. The hydraulic cylinder 307 is connected to the cover plate 2 via the fixing plate 306. A flexible frame 301 is hinged to the end of the push rod 305. When the inner layer contracts, it forms folds (fold depth ≥ 30 mm) to ensure complete coverage of the water surface. A sealing ring 402 connects the drain pipe 4 to the water tank 1, and a valve module 401 is installed on the drain pipe 4.

[0026] Rainwater flows into the central disc 202 through the water channel 302 at the top of the cover plate 2. After the filter plate 205 (material: 304 stainless steel perforated mesh, 2mm aperture) filters out large particles of impurities, the water flows into the flexible inner layer 308 along the water flow ring plate 203. The pressure sensing ball 304 monitors the water volume through a built-in sensor. When the liquid level reaches the threshold, the hydraulic cylinder 307 drives the push rod 305 to unfold the flexible frame 301, so that the flexible inner layer 308 (material: TPU coated nylon cloth) is fully opened to form a funnel-shaped collection surface.

[0027] When rainwater passes through the separator 105 on the outer layer of filter element 103, impurities are intercepted by the partition plate and settle to the bottom of the tank; clean water enters the central chamber 107 through filter holes 104 to complete primary filtration.

[0028] After receiving instructions from the PLC control cabinet, the control battery pack supplies power to the DC motor and frequency converter, activating its pressure pump 210 to draw water from the central chamber 107. The water flows through the water lifting pipe 209 into the spray plate 208. The pressure pump 210, controlled by frequency converter, achieves pressure regulation from 0-0.5MPa. The sprayer (model: SUD15-01) atomizes and sprays the water. The lithium battery pack 212 powers the rotary device, causing it to rotate and drive the brush holder 213 inside the rotating disk 215 to rotate. Synchronously, the rotating disk 215 drives the spray plate 208 to rotate (speed 0-5r / min), achieving 360° uniform self-cleaning and irrigation.
