Description

Technical Field

[0001] This utility model relates to the field of rainwater recycling technology, specifically to a rainwater collection and irrigation device for gardens. Background Technology

[0002] In landscaping facilities, a large proportion of water is wasted due to irrigation of plants and green spaces. Watering plants is usually done by pumping water, and when the output is large, the excess water is wasted, which is not conducive to water conservation. At the same time, gardens do not have the ability to store water. After a large amount of rainwater falls to the ground, it collects into streams and drains out, and quickly seeps into the ground, making it unusable for watering garden trees.

[0003] In the prior art, patent document CN205946783U discloses a rainwater harvesting and irrigation device for gardens. In this solution, rainwater flows to both sides of the ridges, facilitating rainwater collection and storage. Irrigation of trees is achieved through water pumps and irrigation nozzles. This solution primarily relies on rainwater collection ponds for rainwater collection. However, this solution requires constructing drainage ditches and setting up ridges on the green slopes, increasing the steps involved in garden construction and affecting aesthetics.

[0004] Patent document CN207244713U discloses an urban rainwater harvesting and irrigation device. It features seepage holes in the walls of irrigation and drainage ditches and intercepting valves at the bottom. When there is excessive rainwater, it can drain into the sewer system through the irrigation and drainage ditches. When there is excessive rainwater in the upper soil layer, it can seep into the irrigation and drainage ditches through the seepage holes, thereby reducing excess moisture in the upper soil layer and preventing root rot in plants. Rainwater in the irrigation and drainage ditches is limited by the height of the intercepting valves; rainwater below the valve height is accumulated. When the soil moisture drops below the valve height, the accumulated rainwater can seep into permeable gabions through the seepage holes, irrigating the plants and promoting their growth. However, after rainwater is intercepted between the two intercepting valves, the water between them connects to the soil through the seepage holes and permeable gabions. This causes the plant roots in the soil to be soaked in water for extended periods, making them prone to root rot.

[0005] Patent document CN213848055U discloses a rainwater irrigation device for highways. Rainwater enters a rainwater collection tank and then a sedimentation tank, where impurities settle. The water is then conveyed to a drain pipe via a screw conveyor and discharged. The clean water in the sedimentation tank flows through a second pipe into a storage tank, improving the cleanliness of the rainwater entering the irrigation system. This technical solution relies on a screw conveyor and a motor to clean the settled sediment in order to ensure rainwater cleanliness, resulting in high overall equipment costs. Utility Model Content

[0006] The main purpose of this utility model is to provide a garden rainwater collection and irrigation device that allows rainwater to be collected after sedimentation, making it convenient to clean the sedimented soil.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: A rainwater harvesting and irrigation device for gardens includes a collection component embedded in a strip between a road and the lower end of a green slope. The collection component includes a collection trough, the height of the trough near the green slope being greater than the height of the lower end of the green slope, and the height of the trough near the road being greater than the height of the road surface. A filter component is installed in the upper end of the collection trough, and a guide plate is fixed to the lower part of the filter component. A lower plate is placed in the lower end of the collection trough, and an overflow plate is fixed to the upper part of the lower plate. The end of the lower plate facing the road is adjacent to the road-facing side of the collection trough. The inner walls of the overflow plate and the inner wall of the collection tank near the green slope form a clear water chamber, and the inner wall of the overflow plate and the inner wall of the collection tank near the road form a sedimentation chamber. Rainwater passing through the filter components above the clear water chamber enters the sedimentation chamber for sedimentation under the guidance of the guide plate. A water storage tank is pre-buried in the green slope. The clear water chamber and the water storage tank are connected by an inlet pipe. A submersible pump is installed in the water storage tank. An outlet pipe is installed at the outlet end of the submersible pump. The upper end of the outlet pipe passes through the water storage tank and is connected to the spraying components on the green slope.

[0008] Specifically, a fixing plate and a baffle are fixed on the inner wall of the collection trough near the green slope. The baffle is located above the fixing plate, and the filter plate is located in the collection trough above the baffle. The baffle blocks the end of the filter plate facing the green slope. Multiple support rods are fixed on the lower end of the filter plate near the road. One end of the support rod is fixedly connected to the lower end of the filter plate, and the other end of the support rod is inserted into the opening of the fixing plate. The insertion and cooperation between the support rod and the fixing plate can support the end of the filter plate facing the road. The end of the filter plate facing the road contacts the inner wall of the collection trough near the road. The support rod passes through the guide plate and is fixedly connected to the guide plate.

[0009] Specifically, the support rod includes an inclined part and a vertical part. The upper end of the inclined part is fixedly connected to the lower end of the filter plate near the road, and the lower end of the inclined part is fixedly connected to the upper end of the vertical part. The vertical part passes through an opening on the fixed plate.

[0010] Specifically, the end of the guide plate facing the road is tilted downwards, the end of the guide plate facing the green slope is flush with the end of the baffle facing the road, and the end of the guide plate facing the green slope is located above the fixed plate.

[0011] Specifically, the water storage tank is a brick-built tank with a waterproof layer on the inner wall.

[0012] Specifically, a support rod is fixed on the overflow plate. The support rod is perpendicular to the overflow plate. One end of the support rod contacts the inner wall of the collection tank on the side closer to the road, and the other end of the support rod contacts the inner wall of the collection tank on the side closer to the green slope.

[0013] Specifically, an inlet hole is provided on the side wall of the collection tank near the road. The lower end of the inlet hole is flush with the road surface, and a filter screen is fixed inside the inlet hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the coordinated design of the guide plate and overflow plate, the guide plate directs the rainwater flow in a specific direction. After entering the collection trough, the rainwater automatically flows into the sedimentation chamber for settling, ensuring high cleanliness of the collected rainwater. The height setting of the collection trough (higher than the lower end of the slope on the side near the green slope, and higher than the road surface on the side near the road) effectively intercepts rainwater, achieving initial sedimentation and reducing the inflow of impurities such as silt into subsequent systems. The filter plate blocks large debris, and the filter screen in the inlet hole specifically filters suspended matter such as leaves in the rainwater from the road, preventing pipe blockage. After the rainwater settles in the sedimentation chamber, the upper layer of clear water automatically flows into the clear water chamber through the overflow plate. The rainwater in the clear water chamber enters the storage tank for storage, ensuring stable water quality suitable for irrigation.

[0015] 2. The filter plate, support rods, and guide plate can be moved vertically upwards as a whole, simplifying the cleaning process of settled soil. When the lower plate and overflow plate are removed, most of the sediment is carried away, while the inner wall of the collection tank near the road is unobstructed, making it easy to scrape off residual soil with tools. The support rods position the overflow plate and lower plate, and the support rods, fixing plates, and baffles work together to support the filter plate without hindering disassembly, reducing maintenance difficulty and labor costs.

[0016] 3. After collection, rainwater is directly stored in a pre-buried water storage tank. Automated irrigation is achieved through submersible pumps and sprinkler systems, effectively utilizing rainwater resources and reducing reliance on external water sources. The end caps of the water storage tanks are detachable and fixed, facilitating pump maintenance and sediment removal, thus improving the long-term reliability of the system.

[0017] 4. The overflow plate and the lower plate are in close contact with the inner wall of the collection tank through the support rods to ensure the stability of the device under the impact of rainwater; the baffle and the fixing plate support the filter plate to prevent displacement or deformation, and the inclined and vertical parts of the support rods optimize the stress distribution.

[0018] 5. The entire device is embedded between roads and green slopes, making full use of the terrain. The inlet design also takes into account the road drainage function, enhancing the practicality and adaptability of the device in the garden environment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figures 1-5 As shown, a rainwater harvesting and irrigation device for gardens includes a collection component 7 embedded between the lower end of a road 1 and a green slope 2.

[0027] The collection component 7 includes a collection tank 701, a filter component is provided in the upper part of the collection tank 701, and a guide plate 709 is fixed in the lower part of the filter component.

[0028] A lower plate 702 is placed inside the lower end of the collection tank 701. An overflow plate 703 is fixed to the upper end of the lower plate 702. The end of the lower plate 702 facing the road 1 contacts the inner wall of the collection tank 701 on the side close to the road 1. A clear water chamber is formed between the overflow plate 703 and the inner wall of the collection tank 701 on the side close to the green slope 2. A sedimentation chamber is formed between the overflow plate 703 and the inner wall of the collection tank 701 on the side close to the road 1. Rainwater passing through the filter component above the clear water chamber enters the sedimentation chamber for sedimentation under the guidance of the guide plate 709.

[0029] A support rod 704 is fixed on the overflow plate 703. The support rod 704 is perpendicular to the overflow plate 703. One end of the support rod 704 contacts the inner wall of the collection tank 701 near the road 1, and the other end of the support rod 704 contacts the inner wall of the collection tank 701 near the green slope 2. By setting the support rod 704, the overflow plate 703 and the lower plate 702 can be positioned within the collection tank 701.

[0030] A water storage tank 3 is pre-embedded within the green slope 2. The clear water chamber is connected to the water storage tank 3 via an inlet pipe 8. A submersible pump 5 is installed inside the water storage tank 3, and an outlet pipe 6 is installed at the outlet end of the submersible pump 5. The upper end of the outlet pipe 6 passes through the water storage tank 3 and connects to the spraying components on the green slope 2. The water storage tank 3 is a brick-built water tank, and the inner wall of the water storage tank 3 is equipped with a waterproof layer. An end cap 4 is detachably and fixedly connected to the upper end of the water storage tank 3.

[0031] A fixing plate 705 and a baffle 706 are fixed on the inner wall of the collection tank 701 on the side near the green slope 2, with the baffle 706 located above the fixing plate 705.

[0032] The filter plate 707 is located in the collection trough 701 above the baffle 706. The baffle 706 blocks the end of the filter plate 707 facing the green slope 2. Multiple support rods 708 are fixed to the lower end of the filter plate 707 near the road 1. One end of the support rod 708 is fixedly connected to the lower end of the filter plate 707, and the other end of the support rod 708 is inserted into the opening of the fixing plate 705. The insertion and cooperation between the support rod 708 and the fixing plate 705 can support the end of the filter plate 707 facing the road 1. The end of the filter plate 707 facing the road 1 is in contact with the inner wall of the collection trough 701 near the road 1.

[0033] The support rod 708 passes through the guide plate 709, and the support rod 708 is fixedly connected to the guide plate 709.

[0034] The support rod 708 includes an inclined part 7081 and a vertical part 7082. The upper end of the inclined part 7081 is fixedly connected to the lower end of the filter plate 707 on the side near the road 1. The lower end of the inclined part 7081 is fixedly connected to the upper end of the vertical part 7082. The vertical part 7082 passes through the opening on the fixing plate 705.

[0035] The guide plate 709 is tilted downward at the end facing the road 1, and the end of the guide plate 709 facing the green slope 2 is flush with the end of the baffle 706 facing the road 1. The end of the guide plate 709 facing the green slope 2 is located above the fixed plate 705.

[0036] During rainfall, rainwater from the green slope 2 enters the collection tank 701 through the filter plate 707. Rainwater passing through the filter plate 707 above the clear water chamber is guided by the guide plate 709 and enters the sedimentation chamber for sedimentation. Rainwater passing through the filter plate 707 above the sedimentation chamber directly enters the sedimentation chamber for sedimentation. After sedimentation in the sedimentation chamber, the upper layer of rainwater enters the clear water chamber through the upper end of the overflow plate 703. The rainwater in the clear water chamber enters the storage tank 3 through the inlet pipe 8.

[0037] When it is necessary to use the rainwater in the water storage tank 3 to irrigate the plants on the green slope 2, the submersible pump 5 is started. The submersible pump 5 outputs the rainwater in the water storage tank 3 through the outlet pipe 6 to the spraying assembly and sprays it out, thereby realizing the use of the rainwater in the water storage tank 3 to irrigate the plants on the green slope 2.

[0038] When it is necessary to clean the sediment in the settling chamber, the filter plate 707 is pulled vertically upwards. The filter plate 707 drives the support rod 708 and the guide plate 709 to move upwards. Since the end of the guide plate 709 facing the green slope 2 is flush with the end of the baffle 706 facing the road 1, and the end of the guide plate 709 facing the green slope 2 is above the fixed plate 705, the baffle 706 will not obstruct the upward movement of the guide plate 709 when the support rod 708 and the guide plate 709 move upwards. During the vertical upward movement of the filter plate 707, the support rod 708, and the guide plate 709, the vertical part 7082 of the support rod 708 retracts upwards from the opening in the fixed plate 705.

[0039] Then, the overflow plate 703, support rod 704 and lower plate 702 are pulled vertically upward, so that the lower plate 702 remains in contact with the inner wall of the collection tank 701 on the side near the road 1 during the upward movement, and the lower plate 702 can carry out most of the sediment in the sedimentation chamber during the upward movement.

[0040] When it is necessary to clean the residual soil in the collection trough 701, since there are no obstructions on the inner wall of the collection trough 701 on the side close to the road 1, it is convenient to use tools to contact the inner wall of the collection trough 701 on the side close to the road 1 and scrape out the residual soil in the collection trough 701.

[0041] The guide plate, support rod 708 and guide plate 709 are moved out of the collection tank 701 as a whole to facilitate the cleaning of the soil in the collection tank 701.

[0042] Example 2: Based on Example 1, referring to... Figures 1-5 As shown, the height of the collection trough 701 on the side closer to the green slope 2 is greater than the height of the lower end of the green slope 2, and the height of the collection trough 701 on the side closer to the road 1 is greater than the height of the road surface of the road 1.

[0043] An inlet hole 710 is provided on the side wall of the collection tank 701 near the road 1. The lower end of the inlet hole 710 is flush with the road surface of the road 1, and a filter screen 711 is fixed inside the inlet hole 710.

[0044] As rainwater flows from the green slope 2 into the collection trough 701, the side wall of the collection trough 701 near the green slope 2 can block the rainwater, allowing the rainwater flowing down from the green slope 2 to undergo initial sedimentation after being intercepted.

[0045] Rainwater on road 1 can be blocked by the side wall of the collection tank 701 near road 1. When the rainwater on road 1 passes through the inlet 710, it can be filtered by the filter screen 711. By setting the inlet 710 and the filter screen 711, when draining water from road 1, impurities such as leaves can be prevented from entering the collection tank 701, further ensuring the cleanliness of the collected rainwater.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
