Description

Technical Field

[0001] This application belongs to the field of lawn drainage technology, and in particular relates to a lawn base drainage structure. Background Technology

[0002] A lawn is a densely planted area of ​​perennial, low-growing herbaceous plants that is established or maintained by human hands to serve a greening and beautifying purpose. When constructing a lawn, drainage structures need to be installed in advance to prevent the lawn from becoming unusable due to water accumulation during rainy weather. Drainage structures are required during the lawn drainage process.

[0003] The existing utility model with authorization announcement number CN217998328U discloses a slopeless lawn drainage structure, including an outer drainage sleeve, a baffle plate fixedly installed on the inner diameter surface of the outer drainage sleeve, an inner drainage sleeve provided inside the outer drainage sleeve, and an inner support seat fixedly installed inside the inner drainage sleeve.

[0004] Using the above technical solution, the inner and outer drainage sleeves can be quickly connected, and the cover plate and inner drainage sleeve can be quickly connected via positioning rods and positioning holes. The outer and lower drainage sleeves can be quickly installed, making overall installation convenient and operation simple. Water flows into the inner drainage sleeve through drainage channel one on the cover plate, passes through drainage channel two inside the inner drainage sleeve, and enters the outer drainage sleeve. The outer drainage sleeve can then transmit the water flow to the main pipe through the lower drainage sleeve and lower drainage pipe. During the drainage process, drainage channel one and drainage channel two provide two barriers, effectively preventing foreign objects from entering the main pipe. The design is reasonable and easy to use. However, while the above technical solution can drain rainwater from the lawn promptly during light rainfall, it cannot effectively drain large amounts of rainwater during heavy rainfall due to the unchanged drainage efficiency, leading to water accumulation on the lawn and affecting its usability.

[0005] Therefore, we propose a lawn base drainage structure to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem that existing technologies cannot drain large amounts of rainwater in a timely manner, and to propose a drainage structure for lawn base layers.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A lawn base drainage structure includes a lawn base body, a filter baffle is installed inside the lawn base body, a drainage pipe is fixedly connected to the inner wall of the lawn base body, a snap-fit ​​ring is fixedly connected to the inner wall of the filter baffle, a connecting hose is slidably connected inside the snap-fit ​​ring, the bottom end of the connecting hose passes through the filter baffle and the drainage pipe in sequence and extends into the interior of the drainage pipe, an extension hose is fixedly connected to the bottom end of the connecting hose, the extension hose is slidably connected to the interior of the drainage pipe, a buoyancy ball is fixedly connected to the outer surface of the connecting hose, the outer surface of the buoyancy ball is in contact with the upper surface of the filter baffle, and an atmospheric connection pipe is fixedly connected to the top end of the connecting hose.

[0009] By incorporating a drainage pipe, a connecting hose, an extension hose, a buoyancy ball, and an atmospheric connection pipe, the connecting hose slides within a snap ring, and the extension hose slides within the drainage pipe inside the main body of the turf base. During heavy rainfall, the buoyancy ball floats on the water surface due to its buoyancy. The atmospheric connection pipe, fixed to the buoyancy ball, connects to the connecting hose, allowing the extension hose to also connect to the atmosphere within the drainage pipe, thus accelerating the drainage of the turf base drainage structure.

[0010] Preferably, the upper surface of the lawn base layer is provided with a snap-fit ​​groove, and the outer surface of the filter baffle is fixedly connected with an installation frame, which is snapped into the inside of the snap-fit ​​groove.

[0011] With the addition of a snap-fit ​​groove and mounting bracket, the snap-fit ​​groove on the main body of the lawn base allows the mounting bracket to be snapped into it, thus enabling the filter baffle to be securely installed at the water inlet of the drainage structure of the main body of the lawn base.

[0012] Preferably, the inner bottom wall of the snap-fit ​​groove is provided with two sets of positioning holes, and the bottom surface of the mounting bracket is fixedly connected with two sets of positioning posts, each set of positioning posts being snapped into the inside of the positioning hole.

[0013] By providing positioning holes and positioning posts, the mounting bracket can be positioned in the snap-fit ​​groove by the positioning posts being snapped into the positioning holes, thus ensuring stable installation of the filter baffle.

[0014] Preferably, the inner bottom wall of the snap-fit ​​groove is provided with a connecting groove, and the inner wall of the lawn base body is provided with two drainage channels, each of which is connected to the connecting groove.

[0015] By incorporating connecting channels and drainage channels within the main body of the turf base, the drainage pipes can be supplemented to facilitate drainage, thereby improving the drainage rate of the turf base drainage structure.

[0016] Preferably, the inner bottom wall of the connecting groove is provided with a drainage groove and a sliding hole, both of which are connected to a drainage pipe, and the connecting hose is slidably connected inside the sliding hole.

[0017] By incorporating drainage channels and sliding holes, the drainage channels connect to drainage pipes, facilitating the drainage of water from the lawn substrate. The sliding holes allow the connecting hoses to slide, enabling the drainage pipes to connect to the atmosphere.

[0018] Preferably, a filter screen is snapped into the inside of the drainage trough, and a retaining ring is fixedly connected to the upper surface of the filter screen, with the bottom surface of the retaining ring in contact with the inner bottom wall of the connecting trough.

[0019] By incorporating a filter screen and a retaining ring, the filter screen is used to filter the passing water, and the retaining ring securely holds the filter screen inside the drain trough.

[0020] Preferably, the retaining ring has two rotating rods rotatably connected inside, and the ends of the two rotating rods that are close to each other are fixedly connected to a pull handle.

[0021] The filter screen is equipped with a rotating rod and a pull handle. By manually holding the pull handle, the rotating rod can be easily rotated within the retaining ring, and the pull handle can be used to pull the filter screen.

[0022] Preferably, a limiting filter frame is provided above the filter screen, the bottom surface of the limiting filter frame is in contact with the upper surface of the retaining ring, and the upper surface of the limiting filter frame is fixedly connected to the bottom surface of the filter baffle.

[0023] By setting up a limiting filter frame, the limiting filter frame, which is fixed to the bottom surface of the filter baffle, is used to squeeze the retaining ring, so that the filter screen can be firmly stuck inside the drainage channel to filter rainwater. The limiting filter frame can also pre-filter the passing water.

[0024] In summary, the technical effects and advantages of this application are as follows: This lawn base drainage structure, through the combination of a lawn base body, a filter baffle, a snap ring, and a connecting hose, utilizes the filter baffle within the lawn base body to allow the connecting hose to slide within the snap ring fixed inside the filter baffle. This facilitates the use of the structure connecting both ends of the connecting hose, enabling the drainage structure within the lawn base body to connect with the outside atmosphere, thereby improving the drainage rate of the drainage structure. Furthermore, the combination of the lawn base body, drainage pipe, extension hose, buoyancy ball, and atmospheric connection pipe allows the connecting hose to slide within the snap ring, and the extension hose to slide within the drainage pipe within the lawn base body. When rainfall is heavy, the buoyancy of the buoyancy ball allows it to carry the connecting hose and extension hose along with it. The atmospheric connection pipe fixed to the buoyancy ball connects to the connecting hose, enabling the extension hose to also connect with the atmosphere within the drainage pipe, thus accelerating the drainage of the lawn base drainage structure.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Reference Figure 1-2A lawn base drainage structure includes a lawn base body 1, a filter baffle 5 is provided inside the lawn base body 1, a snap-fit ​​groove 8 is provided on the upper surface of the lawn base body 1, and an installation frame 4 is fixedly connected to the outer surface of the filter baffle 5. The installation frame 4 is snapped into the inside of the snap-fit ​​groove 8. By utilizing the snap-fit ​​groove 8 on the lawn base body 1, the installation frame 4 can be snapped into its inside, thereby enabling the filter baffle 5 to be stably installed at the water inlet of the drainage structure of the lawn base body 1.

[0032] Reference Figure 2-3 The inner bottom wall of the snap-fit ​​groove 8 is provided with two sets of positioning holes 9. The bottom surface of the mounting bracket 4 is fixedly connected with two sets of positioning posts 13. Each set of positioning posts 13 is snapped into the inside of the positioning hole 9. By snapping the positioning posts 13 into the inside of the positioning hole 9, the mounting bracket 4 can be installed into the snap-fit ​​groove 8 for positioning, thereby stably installing the filter baffle 5.

[0033] Reference Figure 1-2 The inner wall of the lawn base body 1 is fixedly connected to a drainage pipe 2. The inner bottom wall of the snap-fit ​​groove 8 is provided with a connecting groove 10. The inner wall of the lawn base body 1 has two drainage troughs 3, each of which is connected to the connecting groove 10. By using the connecting groove 10 and the two drainage troughs 3 in the lawn base body 1, the drainage pipe 2 can be assisted in drainage, thereby improving the drainage rate of the lawn base drainage structure.

[0034] Reference Figure 1-3 A snap-fit ​​ring 15 is fixedly connected to the inner wall of the filter baffle 5. A connecting hose 16 is slidably connected inside the snap-fit ​​ring 15. The bottom end of the connecting hose 16 passes through the filter baffle 5 and the drainage pipe 2 and extends into the interior of the drainage pipe 2. A drainage groove 11 and a sliding hole 12 are respectively opened on the inner bottom wall of the connecting groove 10. Both the drainage groove 11 and the sliding hole 12 are connected to the drainage pipe 2. The connecting hose 16 is slidably connected inside the sliding hole 12. The drainage groove 11 is used to connect with the drainage pipe 2 to facilitate the drainage of water on the lawn base layer. The sliding hole 12 facilitates the sliding of the connecting hose 16 to facilitate the connection between the drainage pipe 2 and the atmosphere.

[0035] Reference Figure 3-4 The bottom end of the connecting hose 16 is fixedly connected to the extension hose 17, which is slidably connected to the inside of the drain pipe 2. A filter screen 18 is snapped into the inside of the drain trough 11. A retaining ring 19 is fixedly connected to the upper surface of the filter screen 18. The bottom surface of the retaining ring 19 is in contact with the inner bottom wall of the connecting trough 10. The filter screen 18 is used to filter the passing water, and the retaining ring 19 is used to make the filter screen 18 firmly snapped into the inside of the drain trough 11.

[0036] Reference Figure 4The retaining ring 19 has two rotating rods 20 inside. The two rotating rods 20 are fixedly connected to a pull handle 21 at their close ends. By manually holding the pull handle 21, the rotating rods 20 can be easily rotated inside the retaining ring 19, and the filter screen 18 can be easily pulled by using the pull handle 21.

[0037] Reference Figure 1-3 A buoyancy ball 6 is fixedly connected to the outer surface of the connecting hose 16. The outer surface of the buoyancy ball 6 is in contact with the upper surface of the filter baffle 5. An atmospheric connecting pipe 7 is fixedly connected to the top of the connecting hose 16. A limiting filter frame 14 is provided above the filter screen 18. The bottom surface of the limiting filter frame 14 is in contact with the upper surface of the retaining ring 19. The upper surface of the limiting filter frame 14 is fixedly connected to the bottom surface of the filter baffle 5. The limiting filter frame 14 fixed to the bottom surface of the filter baffle 5 is used to squeeze the retaining ring 19, so that the filter screen 18 can be firmly stuck inside the drainage trough 11 to filter rainwater. The limiting filter frame 14 can also pre-filter the passing water.

[0038] Working Principle: When using this lawn base drainage structure, first, manually pull the handle 21 to engage the filter screen 18 into the drainage channel 11, and make the bottom surface of the retaining ring 19 contact the inner bottom wall of the connecting channel 10. Then, manually engage the mounting bracket 4 into the snap-fit ​​groove 8 on the lawn base body 1, simultaneously engaging the positioning post 13 into the positioning hole 9 to position the mounting bracket 4 in the snap-fit ​​groove 8. The limiting filter bracket 14 fixed to the bottom surface of the mounting bracket 4 can then compress the retaining ring 19 in the connecting channel 10. This allows the drain, composed of the filter screen 18, retaining ring 19, limiting filter bracket 14, mounting bracket 4, and filter baffle 5, to filter rainwater entering the drainage pipe 2 and drainage culvert 3. When the lawn base experiences heavy rainfall, the drainage structure... If the drainage rate remains constant, a large amount of rainwater will accumulate on the lawn substrate, affecting its usability. The accumulated water will cause the buoyancy ball 6 to float on the surface. Since the buoyancy ball 6, along with the connecting hose 16, slides within the locking ring 15, and the connecting hose 16 and extension hose 17 are made of flexible material, and the drainage pipe 2 and extension hose 17 are slightly inclined upwards, pulling the connecting hose 16 will simultaneously pull the extension hose 17 to slide within the drainage pipe 2. This allows the connecting hose 16 and extension hose 17 to connect with the atmospheric connection pipe 7, which in turn connects to the atmosphere, thus connecting the drainage pipe 2 to the atmosphere. This prevents negative pressure within the drainage pipe 2, facilitating smooth drainage and accelerating the drainage rate of the drainage structure, thereby reducing the problem of water accumulation on the lawn substrate.
