Description

Technical Field

[0001] This utility model relates to the field of flower box and container technology, specifically a time-delaying ecological flower box. Background Technology

[0002] With the impact of global weather changes, the drainage capacity of some regions and cities is no longer compatible with the unpredictable rainfall. Municipal roads are an important source of rainwater for urban drainage. Excessive, rapid, and prolonged rainfall can overload road drainage systems, leading to rapid water accumulation and flooding, which greatly affects the normal operation of the city, citizens' travel, and safety hazards.

[0003] With the popularization and application of sponge cities, the use of multiple methods such as "retention, storage, infiltration, purification, utilization, and drainage" to achieve multi-level runoff rainwater control has become an important approach to urban rainwater drainage control. In order to meet the needs of cities to drain water quickly and avoid or delay water accumulation, existing roads, parks, communities and other areas that need to be planted can be improved by modifying the structure of flower boxes to regulate and delay the entry of rainwater into the drainage system and prevent a certain amount of rainfall from entering the ground too early and too quickly, thereby reducing drainage pressure.

[0004] In view of the above problems, this utility model designs a time-delay ecological flower box that can effectively regulate and control rainfall. It not only effectively utilizes rainfall as a water source for plants, but also purifies the quality of rainwater. Furthermore, it can control the discharge rhythm to reduce the pressure on urban drainage. The entire device itself does not require manual intervention and makes a positive contribution to improving urban drainage quality, regulating urban flooding, beautifying the environment, and purifying the air. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a time-delayed ecological flower box that can effectively regulate and control rainfall. It not only effectively utilizes rainfall as a water source for plants but also purifies the quality of rainwater. Furthermore, it can control the discharge rhythm to reduce the pressure on urban drainage. The entire device itself requires no manual intervention and makes a positive contribution to improving urban drainage quality, regulating urban flooding, beautifying the environment, and purifying the air.

[0006] To achieve the above objectives, this utility model provides a regulating and delaying ecological flower box, including a regulating water tank and a base below it. A green plant box and a filter media box are installed above the regulating water tank. A filter plate is installed inside the filter media box, and a lower water tank is located below the filter plate. A slow-release water collection hopper is installed inside the lower water tank. A slow-release delay pressure spring is installed at the bottom of the slow-release water collection hopper, and the slow-release delay pressure spring is connected to a delay connecting rod. A slow-release delay flow restrictor is installed on the narrow side below the slow-release water collection hopper. An outer barrel is installed inside the regulating water tank and below the lower water tank. An inner barrel of the same height is installed inside the outer barrel. A slow-release drainage float is installed around the outer barrel. An overflow filter screen is installed on the outer wall of the outer barrel, at the top but not reaching the bottom of the lower water tank. A pressure needle is installed on the inner side of the slow-release drainage float. The lower part of the outer side of the release and drainage float is provided with a slow-release intercepting drainage hole. One end of the slow-release drainage hose is connected to the slow-release intercepting drainage hole, and the other end of the slow-release drainage hose is connected to the inner tank. The float is started by a water pipe located inside the storage tank and outside the outer tank. The bottom of the float is connected to the float starter plate, and the top of the float is connected to the filter cap located at the bottom of the lower tank. The bottom of the delay linkage is connected to the delay stop cone valve plate. The bottom of the inner tank is provided with a drainage cone port. An overflow drain is provided between the bottom of the inner tank and the bottom of the outer tank. A rainwater drain is provided below the outer tank. A float plate is provided on the base and inside the outer tank. The float plate is connected to the stop valve plate through a valve plate linkage supported by a bracket. A drain port extending into the base is connected below the stop valve plate.

[0007] A water storage layer for plants is installed at the bottom of the plant planting box.

[0008] Several capillary water supply columns are installed inside the plant water storage layer.

[0009] The capillary water supply column extends into the interior of the planter box.

[0010] Several limiting outlets are installed between adjacent capillary water supply columns and on the regulating water tank.

[0011] The top of the side wall of the plant water storage layer is equipped with water passage holes.

[0012] The water passage is connected to the lower water tank.

[0013] The slow-release water collection hopper has a conical structure that is wider at the top and narrower at the bottom.

[0014] The planter box is filled with an ecological medium.

[0015] The delayed-closing cone valve plate has a trapezoidal structure that is wider at the top and narrower at the bottom. The upper width of the delayed-closing cone valve plate is greater than the opening width formed by the bottom of the drain cone.

[0016] Compared with existing technologies, this invention utilizes a slow-release water collection hopper, a delay linkage, and a slow-release delay pressure spring to seal the bottom of the inner tank for water storage, based on varying rainfall amounts and durations. This prevents rainwater from being directly discharged and putting pressure on roads and drainage systems. Subsequently, as the water level rises due to continuous rainfall, the slow-release drainage float is raised to close the drain outlet at the bottom of the storage tank, further increasing the storage capacity of the tank and reducing rainwater discharge pressure. Furthermore, as the water level rises, a plant-based water storage layer can be used for partial water storage, further enhancing the delayed water storage effect.

[0017] When the rainwater volume exceeds the maximum storage capacity, the system initiates initial drainage through the overflow filter. Subsequently, the slow-release delay flow limiter begins drainage at a set flow rate. This flow rate setting can be achieved through threaded openings in the flow limiter or ball valves, and the system can rapidly discharge rainwater based on whether the rainfall has stopped and the external drainage pressure. During this process, the storage tank also helps to settle impurities in the rainwater, ensuring that the rainwater discharged through the slow-release drainage hose is clean, thus avoiding pressure on the external drainage system. Furthermore, the water in the plant water storage layer, under the action of the limiting drain outlet, can retain some rainwater to replenish the moisture of the plants in the green planting box. Therefore, this invention can greatly improve the function of delayed rainfall storage, significantly reduce the pressure on the external drainage system, and achieve automatic storage and drainage without manual intervention. It also has the functions of purifying rainwater and replenishing vegetation moisture, meeting the design elements of a sponge city and providing effective, scientific, and environmentally friendly benefits for urban flood control.

[0033] The planter box 3 is filled with ecological medium 3-1.

[0034] The delayed-closing cone valve plate 7-1 has a trapezoidal structure that is wider at the top and narrower at the bottom. The upper width of the delayed-closing cone valve plate 7-1 is greater than the opening width formed by the bottom of the drain cone port 7-2.

[0035] Working principle:

[0036] This utility model requires minimal adjustment during use. When rain falls above the flower box, the rainwater flows along the downpipe or directly into the open filter media box 5. After being buffered and filtered by the filter plate 5-1, it flows into the cone-shaped slow-release water collection hopper 5-2 below. As the rainwater continues to flow in, the water level inside the slow-release water collection hopper 5-2 rises and the weight gradually increases. Under the action of gravity, the slow-release delay bearing spring 5-6 is compressed and moves downward, simultaneously driving the connected delay connecting rod 5-7 and the connected delay stop cone valve plate 7-1 to move downward at the same time, until the delay stop cone valve plate 7-1 contacts the drain cone port 7-2 and closes the bottom outlet of the inner tank 7.

[0037] As external rainfall continues, the water level in the slow-release water collection hopper 5-2 rises further and flows out from its top, then into the lower water tank 5-8. A small amount of rainwater first flows from the bottom through the filter cap 5-4, then into the float box start-up water pipe 5-5, and then into the float box start-up plate 10. After the water level inside the float box start-up plate 10 rises, the slow-release drainage float box 8 is driven to float up by buoyancy. In the initial state, the pressure needle 8-3 connected to the slow-release drainage float box 8 is in contact with the float block pressure plate 11 below, and the weight of the slow-release drainage float box 8 presses down on the float block pressure plate 11. The downward pressure of the float block pressure plate 11, through the combined action of the valve plate connecting rod 12 and the bracket 12-1, lifts the water stop valve plate 13 and the drain outlet 13-1. When the buoyancy exceeds the weight of the slow-release drainage float box 8, the pressure needle 8-3 connected to the slow-release drainage float box 8 rises along with it. After the pressure needle 8-3 rises and detaches from the float plate 11, the stop valve plate 13 falls and closes the drain outlet 13-1, simultaneously driving the valve plate connecting rod 12 and the float plate 11 to reset. Since the float plate 11 also has a certain buoyancy, when the water level inside the regulating tank 1 rises, the upward buoyancy of the float plate 11, combined with the valve plate connecting rod 12, increases the downward pressure on the stop valve plate 13, thus closing the drain outlet 13-1 more forcefully.

[0038] If the rainfall continues, the water level in the lower water tank 5-8 will continue to rise. Once it reaches a certain level, the water will flow into the plant water storage layer 4 through the water outlet 4-3. The plant water storage layer 4 is equipped with two limiting water outlets 4-2. The top of the limiting water outlets 4-2 is higher than the bottom of the plant water storage layer 4 but lower than the bottom of the green plant box 3, so that some rainwater is stored in the plant water storage layer 4.

[0039] When the water level in the plant water storage layer 4 rises above the top of the limit drain outlet 4-2, it flows into the regulating water tank 1 below. As the water level in the regulating water tank 1 rises, the slow-release drainage float 8 rises with the water level due to buoyancy. The slow-release drainage float 8 drives the slow-release drainage hose 9 connected to it to rise. One end of the slow-release drainage hose 9 is connected to the inner tank 7, and the other end is connected to the slow-release intercepting drainage hole 8-2. The slow-release intercepting drainage hole 8-2 is in the float box start plate 10. Therefore, the slow-release intercepting drainage hole 8-2 can discharge rainwater in the float box start plate 10 to the inner tank 7 to a certain extent through the slow-release drainage hose 9. At the same time, the weight of the slow-release drainage hose 9 and the internal rainwater increases the weight of the slow-release drainage float 8, which is more conducive to the pressure needle 8-3 applying pressure to the float plate 11.

[0040] Furthermore, as the water level in the regulating water tank 1 rises, when it reaches the overflow filter screen 8-1, the incoming rainwater will flow along the overflow filter screen 8-1 into the partition between the inner tank 7 and the outer tank 6 (the inner tank 7 has a smaller diameter than the outer tank 6, forming a partition). Since the bottom of the inner tank 7 and the outer tank 6 are provided with overflow drain outlets 6-1, the overflow rainwater entering through the overflow filter screen 8-1 flows through the partition between the inner tank 7 and the outer tank 6, and then flows through the overflow drain outlet 6-1 to the rainwater drain outlet 6-2 before being discharged.

[0041] The bottom of the slow-release water collection hopper 5-2 is also equipped with a slow-release delay flow limiter 5-3. The slow-release delay flow limiter 5-3 can be set with a flow rate. After the rainfall ends, the water level in the lower water tank 5-8 drops, and the slow-release delay flow limiter 5-3 starts to drain water according to the set flow rate. As time goes by, the rainwater inside the slow-release water collection hopper 5-2 drops and the weight decreases. Under the action of the elastic force, the slow-release delay bearing spring 5-6 pushes the slow-release water collection hopper 5-2 to rise. At the same time, it drives the delay connecting rod 5-7 and the delay stop cone valve plate 7-1 connected to it to rise, opening the lower drainage cone port 7-2 of the inner tank 7. At this time, the rainwater inside the regulating water tank 1 begins to flow into the slow-release drainage hose 9 through the slow-release intercepting drainage hole 8-2 set at the lower part of the slow-release drainage float box 8. Then, it flows into the inner tank 7 through the slow-release drainage hose 9 and is discharged through the rainwater outlet 6-2 at the lower part of the inner tank 7. Impurities in the rainwater inside the regulating water tank 1 settle to the bottom, while clean rainwater is discharged through the slow-release intercepting drainage hole 8-2.

[0042] As the water level in the regulating water tank 1 continues to drop, the slow-release drainage float 8 descends along with the slow-release drainage hose 9. When the pressure needle 8-3 on the slow-release drainage float 8 descends and hits the float plate 11, the float plate 11 is pressed down by gravity, causing the valve plate connecting rod 12 and the stop valve plate 13 connected to it to move upward, opening the drain outlet 13-1. Rainwater containing impurities at the bottom of the regulating water tank 1 is discharged from the drain outlet 13-1.

[0043] Landscape plants can be planted in the green plant planting box 3. The green plant planting box 3 is filled with ecological medium 3-1. The bottom of the green plant planting box 3 is equipped with a capillary water supply column 4-1, which is placed inside the ecological medium 3-1 and in the plant water storage layer 4. The capillary water supply column 4-1 has a water absorption function, maintains the humidity of the ecological medium 3-1, and provides water to the landscape plants planted in the green plant planting box 3.
