Description

Technical Field

[0001] This utility model relates to the field of green roof technology, and in particular to an embedded drainage channel for a green roof. Background Technology

[0002] Green roof technology is a comprehensive technical system that combines engineering waterproofing, roof greening, and energy-saving insulation. It achieves the purpose of greening and beautifying the urban environment by laying soil and planting plants on the roof of a building. In the design and construction of green roofs, the setting of drainage channels is a crucial part.

[0003] However, in existing green roof drainage channels, soil particles are easily carried into the channels during drainage due to water erosion, leading to blockages. This is especially true during periods of heavy rainfall when the water flow is faster and soil erosion is more severe. This not only affects drainage efficiency but can also damage the channel structure. Soil erosion can also cause uneven planting layer thickness, affecting plant growth and the overall aesthetic appeal. Furthermore, when a green roof is subjected to stress, such as from people or equipment, the drainage channels and their supporting structures experience significant impact. Existing drainage channel designs often lack effective shock absorption measures, making the channels prone to deformation or damage under stress, thus affecting their drainage performance and lifespan. In addition, the lack of shock absorption measures may also threaten the overall structural safety of the building. Therefore, an embedded drainage channel for green roofs is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing green roof drainage systems. During drainage, soil particles are easily carried into the drainage channels due to water flow, leading to blockages, especially during periods of heavy rainfall when the water flow is faster and soil erosion is more severe. This not only affects drainage efficiency but can also damage the drainage channel structure. Soil erosion can also cause uneven planting layer thickness, affecting plant growth and the overall aesthetic appeal. Furthermore, when a green roof is subjected to stress, such as from people or equipment, the drainage channel and its supporting structure experience significant impact. Existing drainage channel designs often lack effective shock absorption measures, making the channels prone to deformation or damage under stress, thus affecting drainage performance and service life. Moreover, the lack of shock absorption measures can also threaten the overall structural safety of the building. Therefore, this invention proposes an embedded drainage channel for large green roofs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large roofing embedded drainage trough for planting, comprising a base, an outer frame and an inner frame. The outer frame is slidably connected to the inner walls on both sides of the base. A first elastic block is fixedly arranged between the bottom inner wall of the base and the bottom of the outer frame. The inner frame is arranged inside the outer frame. Absorbent isolation layers are arranged between the inner walls on both sides of the outer frame and both sides of the inner frame. A top cover is arranged on the top of the outer frame. A plurality of grooves are formed in the top of the outer frame, and buckles for connecting the top cover are arranged in the grooves.

[0007] In a possible design, the buckle comprises a connecting block. The connecting block is in a "C" shape. Rotating shafts are fixedly connected to both sides of the buckle, and the two rotating shafts are respectively rotatably connected to the inner walls on both sides of the groove. Through grooves and engaging grooves penetrating through are respectively formed in the top and bottom of the connecting block. Two second elastic blocks are fixedly connected to the bottom of the connecting block, and the two second elastic blocks are symmetrically distributed on both sides of the engaging groove.

[0008] In a possible design, a plurality of clamping blocks are fixedly connected to the bottom of the top cover. An inclined surface is formed on one side of the bottom of the clamping block, and a clamping groove is formed in the bottom of one side of the clamping block. The bottom of the clamping block sequentially penetrates through the through groove and the engaging groove, and the clamping block is clamped and connected to the bottom of the connecting block through the clamping groove.

[0009] In a possible design, a plurality of through limiting grooves are formed in both sides of the base. A plurality of extension shafts are fixedly connected to both sides of the outer frame, and the extension shafts penetrate through the corresponding limiting grooves.

[0010] In a possible design, a plurality of first drainage holes are formed in both sides of the outer frame, and a plurality of second drainage holes are formed in both sides of the inner frame. The second drainage holes and the first drainage holes are arranged in a staggered manner.

[0011] In a possible design, two symmetrical limiting blocks are fixedly connected to the bottom of the top cover. The mutually remote sides of the two limiting blocks respectively contact the inner walls on both sides of the inner frame. Sealing gaskets one are fixedly connected to both sides of the bottom of the top cover, and the bottoms of the sealing gaskets one contact the top of the outer frame. Sealing gaskets two are fixedly connected to the bottoms of the limiting blocks, and the sealing gaskets two contact the top of the inner frame.

[0012] Working Principle: In this application, when planting on a green roof, an installation groove is first opened on the roof. The drainage trough is then placed within the groove, ensuring the top of the roof is higher than the bottom of the first drainage hole. Soil is then filled in, and planting begins. After planting, excess water in the soil is absorbed by the water-absorbing isolation layer through the first drainage hole, and then drains into the inner frame through the second drainage hole before flowing out. The soil, due to the staggered arrangement of the first and second drainage holes and the obstruction of the water-absorbing isolation layer, is not lost with the water. Simultaneously, an elastic block is installed between the base and the outer frame to cushion some of the pressure on the top of the drainage trough, preventing damage. Furthermore, this drainage trough adopts a modular design, allowing for easy assembly and disassembly of all components. When a component is damaged, simply push inwards... Press the connecting block located inside the drainage channel to rotate it inward along the pivot axis to release the locking block and remove the top cover. During installation, simply insert the limiting block between the inner walls on both sides of the outer frame and let the bottom of the locking block pass through the through groove. Then, the inclined surface at the bottom of the locking block will push the top of the locking groove, causing the connecting block to rotate inward to allow the locking block to continue to be inserted. By squeezing the second elastic block, the second elastic block is energized. When the bottom of the locking block disengages from the locking groove, the second elastic block will push the connecting block to rotate under the elastic force, and the bottom of the connecting block will lock into the locking groove on one side of the locking block. At the same time, during the installation process, the first and second sealing gaskets will also be squeezed. After the installation is completed, the first and second sealing gaskets will seal the bottom of the top cover to the top of the outer frame and the top of the inner frame, respectively, to prevent soil from entering.

[0013] Beneficial effects: In this utility model, the embedded drainage channel for a green roof can achieve effective shock absorption through the sliding connection between the outer frame and the base and the setting of the elastic block. When the top of the green roof is subjected to force, such as when people move or equipment is placed, the outer frame can slide inside the base and absorb and disperse the impact force through the elastic block, thereby preventing the drainage channel from deforming or being damaged due to excessive force, improving the service life and drainage performance of the drainage channel, and also enhancing the overall structural safety of the building.

[0014] In this utility model, the embedded drainage trough for a large rooftop planting area, through the staggered arrangement of the water-absorbing isolation layer, drainage hole one, and drainage hole two, can achieve the effect of preventing soil loss and avoiding clogging of the drainage trough. Excess water in the planting soil can be absorbed by the water-absorbing isolation layer through drainage hole one and then discharged through drainage hole two. Soil particles will not be lost with the water due to the staggered arrangement of drainage hole one and drainage hole two and the obstruction of the water-absorbing isolation layer, thus ensuring the unobstructed flow of the drainage trough, while also maintaining the thickness of the planting layer and the growth environment of the plants.

[0015] In this utility model, the embedded drainage channel for a large roof with a planting structure features a snap-fit ​​connection between the top cover and the outer frame, which facilitates easy assembly and disassembly. When it is necessary to repair or replace the drainage channel components, simply press the connecting block inward to release the snap-fit, and the top cover can be easily removed. During installation, simply insert the limiting block between the inner walls on both sides of the outer frame and let the snap-fit ​​pass through the through slot and the snap-fit ​​slot. The snap-fit ​​will be automatically engaged by the elastic force of the second elastic block. At the same time, the first and second sealing gaskets will be compressed and achieve a sealing effect, thereby simplifying the assembly and disassembly process of the drainage channel and improving work efficiency.

[0016] In this invention, the sliding connection between the outer frame and the base, along with the inclusion of elastic block one, effectively reduces shock. When the roof of the green roof is subjected to stress, such as during personnel movement or equipment placement, the outer frame can slide within the base, and the elastic block one absorbs and disperses the impact force. This prevents the drainage trough from deforming or being damaged due to excessive stress, improving its service life and drainage performance. It also enhances the overall structural safety of the building. The staggered arrangement of the water-absorbing isolation layer, drainage hole one, and drainage hole two prevents soil loss and drainage trough blockage. Excess water in the planting soil is absorbed by the water-absorbing isolation layer through drainage hole one and then discharged through drainage hole two. Soil particles are discharged through drainage holes one and two. The staggered design of the second water hole and the blocking effect of the water-absorbing isolation layer prevent water loss, ensuring unobstructed drainage of the drainage channel. This also maintains the thickness of the planting layer and the plant's growth environment. The snap-fit ​​connection between the top cover and the outer frame facilitates easy assembly and disassembly. When repairing or replacing the drainage channel components, simply press the connecting block inward to release the snap-fit, allowing the top cover to be easily removed. During installation, simply insert the limiting block between the inner walls of both sides of the outer frame, allowing the snap-fit ​​to pass through the through groove and the snap-fit ​​groove. The elastic force of the second elastic block automatically snaps the snap-fit, while the first and second sealing gaskets are compressed, achieving a sealing effect. This simplifies the assembly and disassembly process of the drainage channel and improves work efficiency. Attached Figure Description
