Description

Technical Field

[0001] This utility model relates to the field of urban green space, and in particular to a soil aeration and drainage device for urban green space. Background Technology

[0002] Soil permeability, the ability of soil to allow free flow of air and water, is a crucial indicator of soil health. However, urban green spaces commonly suffer from soil compaction, which leads to poor permeability. Prolonged oxygen deficiency can cause decreased root vitality and even death. Current soil aeration and drainage devices are typically complex and costly, making them unsuitable for widespread adoption. While some simpler devices can improve soil permeability, they often overlook the fact that rainwater can seep into the soil along the outer wall of the device, resulting in excessive soil moisture and waterlogging. Furthermore, after heavy rainfall, water accumulates near the plants, making drainage difficult and leading to prolonged waterlogging and oxygen deficiency, ultimately causing root death. Therefore, we propose a soil aeration and drainage device for urban green spaces to address these issues.

[0003] Chinese patent document CN 216492360 U describes a drainage and aeration device for trees suitable for water-rich and rainy soils. This device includes a drainage and aeration pipe and a water collector. The lower end of the drainage and aeration pipe has a set of four symmetrically arranged 5mm diameter aeration holes. The drainage and aeration pipe is placed at an angle. The water collector consists of a rot-resistant wooden handle, a stainless steel rod, and a polyethylene container. While this device can improve soil aeration and promptly remove waterlogging from tree roots, it overlooks the small aeration hole area, which may not meet the plant's aeration needs, and the risk of clogging. Although the drainage and aeration pipe is placed at an angle, it cannot prevent rainwater from entering the soil through the outer wall of the pipe. Therefore, this device has shortcomings and needs improvement. Utility Model Content

[0004] This utility model provides a soil aeration and drainage device for urban green spaces, which solves the problem that after a large amount of rainfall, rainwater can enter the soil along the outer wall of the rainwater device, resulting in excessively high soil moisture content and waterlogging of plants; at the same time, a large amount of water is difficult to drain, and prolonged waterlogging and lack of oxygen can lead to root death.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an urban green space soil aeration and drainage device, including a drainage pipe, a pipe cover at the top of the drainage pipe, a drainage cover on the pipe cover, a water accumulation ring at the bottom of the drainage pipe, a detachable connecting rod on the drainage cover, a connector at one end of the connecting rod, and a rain shield on the drainage pipe.

[0006] In the preferred embodiment, the drain pipe has a hollow structure, multiple vent holes are provided on the drain pipe, a screen is provided on the vent holes, the rain shield rests against the ground, and the top of the drain pipe has a downward-sloping water outlet vent.

[0007] In the preferred embodiment, the rain shield is tilted relative to the drain pipe, and the central axis of the drain pipe is tilted relative to the plant.

[0008] In a preferred embodiment, the pipe cover includes a cover body that rests against the drain pipe, and the cover body is provided with a handle and a threaded hole.

[0009] In a preferred embodiment, the drain cover is provided with a second handle and an external thread, the external thread is connected to a threaded hole, and the bottom of the drain cover is provided with a second threaded hole.

[0010] In a preferred embodiment, the water accumulation ring includes a ring body with a notch on one side, the notch being located on the side of the water outlet vent of the drain pipe.

[0011] In the preferred embodiment, the water accumulation ring is provided with two support pillars, each with a hollow horizontal column. A sliding column is provided on the horizontal column, which rests against the horizontal column. A spring is provided between the horizontal column and the sliding column.

[0012] In a preferred embodiment, the bottom of the connector is provided with arc-shaped grooves on both sides, a platform is provided on the top of the arc-shaped grooves, a second arc-shaped groove is provided on the top of the platform, the outer wall of the connector is provided with an outer sliding wall, the second arc-shaped groove is connected to the outer sliding wall, and a rotating shaft is provided on the top of the connector.

[0013] In the preferred embodiment, one end of the connecting rod is provided with a second external thread, one end of the connecting rod is connected to the second threaded hole of the drain cover, and the other end of the connecting rod is rotatably connected to the rotating shaft.

[0014] The beneficial effects of this invention are as follows: When it rains, the rain shield of the drainage pipe extends outwards, acting as a barrier to block rainwater and allowing it to slowly flow onto the surrounding soil. This prevents rainwater from entering the soil through the outer wall of the rainproof device, thus avoiding excessive soil moisture and preventing waterlogging of the plants. The drainage pipe is equipped with downward-sloping venting holes and multiple ventilation holes to allow air circulation between the plant roots and the outside environment, preventing root death due to lack of oxygen. The downward-sloping venting holes also prevent rainwater from entering the drainage pipe through them.

[0015] When heavy rainfall causes waterlogging near the plant, the vents in the drainage pipe guide the water into the pipe, where it slowly collects in a water-collecting ring at the bottom. Opening the drain cover allows the connecting rod to connect the cover and the connector. Inserting the rod and connector into the drainage pipe allows the connector to connect with the water-collecting ring. Lifting the rod raises the ring, carrying the water with it. When the ring reaches the vent, the water flows out through the opening, draining the water. After drainage, the water-collecting ring, under gravity, reaches the bottom of the drainage pipe. Pressing the rod again disconnects it from the connector. Removing the rod and reinstalling the drain cover completes the drainage process, preventing large amounts of water from accumulating and causing root death due to prolonged waterlogging and oxygen deficiency. This method has significant potential for wider application. Attached Figure Description

Detailed Implementation

[0026] Example 1:

[0027] like Figure 1-8 The urban green space soil aeration and drainage device includes a drainage pipe 1, a pipe cover 2 at the top of the drainage pipe 1, a drainage cover 3 on the pipe cover 2, a water collection ring 4 at the bottom of the drainage pipe 1, a detachable connecting rod 6 on the drainage cover 3, a connector 5 at one end of the connecting rod 6, and a rain shield 103 on the drainage pipe 1. With this structure, when it rains, the rain shield 103 of the drainage pipe 1 extends outwards, acting as a barrier to block rainwater, allowing the rainwater on the drainage pipe 1 to slowly flow onto the surrounding soil. This prevents rainwater from entering the soil through the outer wall of the rain protection device, thus avoiding excessive soil moisture and preventing waterlogging of plants. The drain pipe 1 is provided with a downward-sloping water outlet vent 102, and multiple vents 101 are provided on the drain pipe 1 to allow air circulation between the plant roots and the outside environment, so as to prevent the plant roots from dying due to lack of oxygen. At the same time, the downward-sloping water outlet vent 102 can also prevent rainwater from entering the drain pipe 1 through the water outlet vent 102.

[0028] When heavy rainfall causes water accumulation near the plant, the vent 101 of the drain pipe 1 guides the accumulated water into the drain pipe 1, where it slowly gathers into the water-collecting ring 4 at the bottom of the drain pipe 1. The drain cover 3 on the pipe cover 2 is opened, allowing the connecting rod 6 to connect the drain cover 3 and the connector 5. The connecting rod 6 and connector 5 are then inserted into the drain pipe 1, connecting the connector 5 to the water-collecting ring 4. The connecting rod 6 is then lifted, causing the water-collecting ring 4 to rise, carrying the accumulated water with it. When the water-collecting ring 4 reaches the water outlet vent 102, the water on the water-collecting ring 4 flows out through the notch 402, thus draining water from the entire structure. After the accumulated water is drained, the water ring 4 reaches the bottom of the drain pipe 1 due to gravity. Press the connecting rod 6 again to disconnect the connecting rod 6 from the connecting piece 5. Pull out the pressing connecting rod 6, install the drain cover 3, and the whole device drains, thus avoiding the phenomenon that a large amount of water is difficult to drain and that long-term water accumulation and lack of oxygen will lead to root death.

[0029] In the preferred embodiment, the drain pipe 1 has a hollow structure and multiple ventilation holes 101. Each ventilation hole 101 has a screen, and a rain shield 103 rests against the ground. The top of the drain pipe 1 has a downward-sloping water outlet ventilation hole 102. This structure, with the downward-sloping water outlet ventilation hole 102 and multiple ventilation holes 101, allows air circulation between the plant roots and the outside environment, preventing root death due to oxygen deficiency. Simultaneously, the downward-sloping water outlet ventilation hole 102 also prevents rainwater from entering the drain pipe 1 through it.

[0030] Even when there is no rainfall, the water outlet vent 102 can still serve the purpose of air circulation.

[0031] In the preferred embodiment, the rain shield 103 is inclined relative to the drain pipe 1, and the central axis of the drain pipe 1 is placed at an angle relative to the plant. With this structure, when it rains, the rain shield 103 extends a portion of the drain pipe 1, acting as a barrier to block rainwater, allowing the rainwater on the drain pipe 1 to slowly flow onto the surrounding soil. This prevents rainwater from entering the soil through the outer wall of the rainproof device, thus avoiding excessive soil moisture and preventing waterlogging of the plant.

[0032] In a preferred embodiment, the pipe cover 2 includes a cover body 201 that abuts against the drain pipe 1. The cover body 201 is provided with a handle 202 and a threaded hole 203. With this structure, the drain cover 3 can be opened from the pipe cover 2 so that the connecting rod 6 and the connector 5 can be inserted into the threaded hole 203 to connect the connector 5 to the water collection ring 4.

[0033] In a preferred embodiment, the drain cover 3 is provided with a second handle 301 and an external thread 303, the external thread 303 being connected to a threaded hole 203, and the bottom of the drain cover 3 being provided with a second threaded hole 302. With this structure, the second threaded hole 302 is connected to one end of the connecting rod 6, allowing the connecting rod 6 to be installed and removed from the drain cover 3.

[0034] In a preferred embodiment, the water-collecting ring 4 includes a ring body 401, with a notch 402 on one side of the ring body 401, located on the side of the water outlet vent 102 of the drain pipe 1. With this structure, the ring wall of the ring body 401 can collect accumulated water.

[0035] In a preferred embodiment, the water-collecting ring 4 is provided with two support pillars 403, each with a hollow horizontal column 404. A sliding column 405 is mounted on the horizontal column 404, and the sliding column 405 rests against the horizontal column 404. A spring is provided between the horizontal column 404 and the sliding column 405. With this structure, when the connecting piece 5 and the water-collecting ring 4 are first connected, the connecting rod 6 is pressed down, causing the sliding column 405 to slide relative to the horizontal column 404, allowing the two sliding columns 405 to slide across the arc-shaped groove 501 and rest against the platform 502. When the connecting rod 6 is pulled, it is lifted, causing the connecting piece 5 to lift the water-collecting ring 4.

[0036] In a preferred embodiment, the connector 5 has arc-shaped grooves 501 on both sides of its bottom, a platform 502 on the top of the arc-shaped grooves 501, a second arc-shaped groove 503 on the top of the platform 502, an outer sliding wall 504 on the outer wall of the connector 5, the second arc-shaped groove 503 communicating with the outer sliding wall 504, and a rotating shaft 505 on the top of the connector 5. With this structure, the bottom of the connector 5 is spherical. When the connector 5 needs to be separated from the water-collecting ring 4, the connecting rod 6 is pressed down again, causing the sliding column 405 to pass through the second arc-shaped groove 503 and reach the outer sliding wall 504 of the connector 5. After pulling the connecting rod 6, the connector 5 rotates relative to the connecting rod 6, and the connector 5 disengages from the water-collecting ring 4.

[0037] In the preferred embodiment, one end of the connecting rod 6 is provided with a second external thread, and one end of the connecting rod 6 is connected to the second threaded hole 302 of the drain cover 3. The other end of the connecting rod 6 is rotatably connected to the rotating shaft 505. With this structure, the connecting rod 6 is rotatably connected to the rotating shaft 505, and a torsion spring is provided between the connecting rod 6 and the rotating shaft 505.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
