Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting in gardens, and more particularly to a rainwater harvesting device for use in landscape gardens. Background Technology

[0002] With the acceleration of urbanization and the impact of climate change, the effective collection and utilization of rainwater is increasingly becoming an important issue in landscaping and urban management. In landscape design, the application of rainwater harvesting devices can provide plants with necessary water sources, improving the ecological value and sustainability of the garden. However, existing rainwater harvesting devices have some shortcomings in their design and application.

[0003] First, many rainwater harvesting systems have relatively small storage tanks to meet aesthetic requirements. While this design allows for some integration with the surrounding environment, it limits their ability to collect and store rainwater, making them ill-suited for handling large rainfall volumes. Furthermore, existing underground rainwater harvesting systems are susceptible to contamination during operation. Due to the lack of effective filtration systems, soil, leaves, and other debris can flow into the storage tank with rainwater, causing water pollution. This not only affects the quality of the collected water but may also hinder subsequent reuse and increase the workload of equipment maintenance and cleaning.

[0004] Furthermore, the open design of rainwater harvesting systems' storage tanks often leads to continuous evaporation of water when rainfall stops. Especially in hot weather, the water level in the tank decreases rapidly, resulting in resource waste and reduced water use efficiency. Without effective preventative measures, this becomes one of the drawbacks of rainwater harvesting systems during dry seasons. In cases of heavy rainfall, if the storage tank cannot drain effectively, it may overflow, causing damage or even leakage, impacting the soil and surrounding environment. Therefore, the load-bearing capacity and overflow management mechanisms must be fully considered when designing rainwater harvesting systems. Utility Model Content

[0005] The purpose of this utility model is to provide a rainwater harvesting device for landscape gardens, in order to solve the problems of buried rainwater harvesting devices in the background art being easily contaminated, rainwater harvesting devices being prone to evaporation when exposed to the sun, and the lack of drainage function leading to device damage in the event of excessive water such as heavy rainfall.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rainwater collection device for landscape gardens, comprising a water storage tank, an inlet at the top of the water storage tank, a buoyancy drainage device inside the water storage tank, and an emergency drainage outlet at the bottom of the water storage tank.

[0007] As a preferred embodiment of this utility model, the water inlet includes a filter screen, a water collection basin is provided below the filter screen, a return spring is provided below the water collection basin, a bracket is provided below the return spring, a storage box is provided between the bracket and the return spring, and several overflow holes are provided at the bottom of the storage box.

[0008] As a preferred embodiment of this invention, a sealing ring is provided between the water collection basin and the water storage tank.

[0009] As a preferred embodiment of this utility model, the buoyancy drainage device includes a drain pipe, one end of which extends to the outside of the water storage tank. A water pump is installed on the drain pipe, and a pull controller is installed above the water pump. A floating rope is connected to the pull controller, and a floating ball is connected to one end of the floating rope.

[0010] As a preferred embodiment of this utility model, the water storage tank is provided with a water supply pipe inside, one end of which extends to the outside of the water storage tank, and a water pump is provided on the water supply pipe.

[0011] As a preferred embodiment of this utility model, the emergency drain outlet includes a conical funnel, an emergency drain pipe is provided at the bottom of the conical funnel, a conical plug is provided on the emergency drain pipe, a pull rope is connected to the top of the conical plug, a floating block is provided on the pull rope, the pull rope extends upward to the outside of the top of the water storage tank, and a pull ring is provided at the other end of the pull rope.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. Through the cooperation of the water collection basin and the return spring, the water collection basin descends during rainfall, causing the inlet to open and collect rainwater. After the rainfall stops, the water on the water collection basin evaporates, and the return spring causes the water collection basin to return to its original position. The sealing ring fits in place to achieve a sealing effect and prevent water loss.

[0013] 2. By using the floating ball to pull the floating rope when the water level rises, the water pump can be activated to drain water when the water level is too high, preventing excessive water from damaging the water storage tank.

[0014] 3. The emergency drain at the bottom can be activated by pulling the ring to open the emergency drain in case of emergency. The floating block on the pull rope can expose more of the pull rope when the water level is high, allowing the operator to judge the water level by observing the exposed pull rope.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] This utility model provides a technical solution: a rainwater harvesting device for use in landscape gardens, such as... Figure 1 As shown, it includes a water storage tank 1, a water inlet 2 at the top of the water storage tank 1, a buoyancy drainage device inside the water storage tank 1, and an emergency drain outlet 3 at the bottom of the water storage tank 1.

[0019] like Figure 1-4 As shown, the water inlet 2 includes a filter screen 201, a water collection basin 202 is provided below the filter screen 201, a return spring 203 is provided below the water collection basin 202, a bracket 204 is provided below the return spring 203, a storage box 205 is provided between the bracket 204 and the return spring 203, and several overflow holes 206 are provided at the bottom of the storage box 205.

[0020] like Figure 1-4 As shown, a sealing ring 207 is provided between the water basin 202 and the water storage tank 1. The sealing ring 207 is an adsorbent material. When absorbing water, the sealing ring 207 expands and loses its adsorption force. When dry, the sealing ring 207 loses moisture and shrinks, generating adsorption force. When exposed to sunlight, the sealing ring 207 seals the water inlet 2. When it rains, the raindrops wet the sealing ring 207, making it easier to open as it loses its adsorption force.

[0021] like Figure 4 As shown, the buoyancy drainage device includes a drain pipe 5, one end of which extends to the outside of the water storage tank 1. A water pump 6 is installed on the drain pipe 5, and a pull controller 601 is installed above the water pump 6. A floating rope 602 is connected to the pull controller 601, and a floating ball 603 is connected to one end of the floating rope 602.

[0022] like Figure 4 As shown, a water supply pipe 7 is provided inside the water storage tank 1. One end of the water supply pipe 7 extends to the outside of the water storage tank 1, and a water pump 8 is provided on the water supply pipe 7.

[0023] like Figure 2 , Figure 4 As shown, the emergency drain outlet 3 includes a conical funnel 301, an emergency drain pipe 302 at the bottom of the conical funnel 301, a conical plug 303 on the emergency drain pipe 302, the conical plug 303 and the conical funnel 301 are identical in shape and fit together, a pull rope 304 is connected to the top of the conical plug 303, a floating block 305 is provided on the pull rope 304, the pull rope 304 extends upward to the outside of the top of the water storage tank 1, and a pull ring 306 is provided at the other end of the pull rope 304. When the water level is high, the floating block 305 can make more of the pull rope 304 exposed, and the operator can judge the water level by the exposed pull rope 304.

[0024] In practice, this device will be buried underground in the garden, with only the inlet 2 remaining on the surface, minimizing the impact of deploying rainwater collection devices on the garden's aesthetic environment. When it rains, rainwater is filtered through the filter screen 201 and enters the collection basin 202. As the water volume increases, the weight of the collection basin 202 increases, causing it to compress the return spring 203. The collection basin 202 moves downwards, and the sealing ring 207, wetted by rainwater, loses its absorbency, creating an opening. The inlet 2 opens, and rainwater flows into the storage tank 1. When the rain stops, as the water volume decreases, the weight of the collection basin 202 decreases, causing the return spring 203 to move the collection basin 202 upwards. The sealing ring 207, due to moisture evaporation and contraction, closes the inlet 2, preventing moisture evaporation. When excessive rainfall occurs, water tank 1 is about to overflow. Due to the buoyancy of the water in tank 1, the floating ball 603 rises, causing the floating rope 602 to pull the controller 601, activating water pump 6. Water pump 6 then discharges water through the drain pipe 5 into the garden lake. When the water level drops due to drainage, the floating ball 603 follows the water level, the controller 601 stops pulling, and water pump 6 stops working, controlling the water level. When water is needed, water pump 8 is activated, pumping water through the water supply pipe 7 into the water-using equipment. When equipment maintenance or cleaning of water tank 1 is required to prevent algae or mold growth, the operator pulls the pull ring 306. The pull ring 306 pulls the pull rope 304, raising the conical plug 303. At this time, all the water in water tank 1 will drain into the sewer through the bottom emergency drain pipe 302. The floating block 305 on the pull rope 304 can keep a portion of the pull rope 304 outside the water tank 1 according to the water level of the water tank 1. The operator can judge the water level by the pull rope 304 extending outside the water tank 1.

[0025] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
