Description

Technical Field

[0001] This invention relates to the field of municipal landscaping engineering technology, and in particular to a landscaping drainage system. Background Technology

[0002] Landscape greening is the creation of a beautiful natural environment and recreational space by using engineering technology and artistic means in a certain area, through modifying the terrain (or further building mountains, stacking stones, and managing water), planting trees and flowers, constructing buildings, and arranging garden paths. In the process of landscape greening, transplanting is mostly used to directly plant established trees and flowers into the garden, which facilitates the rapid presentation of greening effects.

[0003] Garden plants require watering during routine maintenance, typically through natural rainwater or manual sprinkling. However, garden green areas often experience waterlogging during heavy rains. Traditional drainage systems have the following drawbacks: 1. Drainage outlets are easily clogged by fallen leaves, requiring frequent manual cleaning; 2. Direct discharge of rainwater wastes irrigation resources; 3. Incomplete separation of impurities leads to siltation and reduced drainage efficiency; 4. Lack of intelligent diversion mechanisms, failing to simultaneously address drainage and water storage needs. While existing technologies incorporate filters or water tanks, they fail to systematically solve the problems of clogging, purification, and coordinated irrigation. Summary of the Invention

[0004] This invention discloses a drainage system for landscaping, which improves upon existing structures and shortcomings to provide a better practical drainage system.

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

The livestock guide channel body has a preset slope along its length. A rotating filter assembly is installed at an angle at the inlet end of the livestock guide channel, with its axis forming an acute angle with the bottom plane of the channel. A conical debris collector is coaxially connected to the end of the rotating filter assembly. A sedimentation chamber body is connected to the outlet end of the livestock guide channel body, with a sliding rail-type sludge collection drawer embedded at its bottom. An ecological water storage tank body is connected to the sedimentation chamber body through an intelligent diverter. A biological partition is vertically fixed inside the ecological water storage tank body. An anti-backflow overflow pipe is provided at the top of the ecological water storage tank body, and an irrigation coupler is connected to its bottom.

[0007] In some embodiments, the main body of the diversion and storage channel includes an inverted trapezoidal channel body, with a flow-guiding groove formed at the junction of its side wall and the channel bottom; a fiber-reinforced mesh is laid at the bottom of the channel body, a filter layer is covered on the fiber-reinforced mesh, a purification layer is provided above the filter layer, and capillary irrigation branch pipes are embedded on both side walls of the channel body.

[0008] In some embodiments, the capillary irrigation branch includes a pipe body with radially arranged micropores on its wall and hydrophilic fiber channels extending axially along the pipe body, wherein hydrophilic fiber bundles are embedded in the hydrophilic fiber channels.

[0009] In some embodiments, the rotating filter cartridge assembly includes a cylinder with its feed end protruding beyond the inlet plane of the main body of the storage channel and having filter holes circumferentially formed; the edges of the filter holes are provided with cutting edge structures, the inner wall of the cylinder is provided with variable pitch spiral blades, and the cylinder is connected to a magnetic levitation shaft system, the magnetic levitation shaft system including a permanent magnet rotor and a stator coil.

[0010] In some embodiments, the intelligent diverter includes a diverting cavity with its pointed wedge end pointing towards the main outlet of the settling chamber; a buoyancy slider is provided on the top of the wedge-shaped diverting cavity; the bottom plate of the buoyancy slider is connected to a double-position baffle, which rotatably shields the water storage passage or the sewage discharge passage.

[0011] In some embodiments, the slide rail type sludge collection drawer includes a drawer frame with roller sets on both sides that cooperate with guide rails at the bottom of the settling chamber body; a mesh structure is installed on the drawer frame, and a magnetic film is sputtered onto its surface; a piezoelectric vibrator is provided at the bottom of the mesh structure.

[0012] In some embodiments, the bio-partition comprises: a partition body having honeycomb pores arrayed on its top, and a photocatalytic coating loaded on the pore walls;

[0013] And a biological packing basket suspended at the bottom of the partition body, the basket being filled with slow-release microbial carriers.

[0014] In some embodiments, the irrigation coupler includes a coupling body, which is arranged vertically along the axis and has an inlet flange connected to the top, an irrigation flange connected to the bottom, and an aeration flange connected to the side wall.

[0015] The inlet flange is connected to the inlet end of the main irrigation pipe, and the main irrigation pipe extends through the irrigation flange to the underground pipe network; the aeration flange is fixedly connected to the jet oxygenation branch pipe, and the end of the jet oxygenation branch pipe is provided with a Venturi nozzle that extends into the middle of the main body of the ecological water storage tank; the main irrigation pipe is spatially orthogonal to the jet oxygenation branch pipe at 90° in the inner cavity of the coupling body; a first solenoid valve is provided on the main irrigation pipe near the inlet flange, and a second solenoid valve is provided on the jet oxygenation branch pipe near the Venturi nozzle; a control circuit board is fixedly installed on the outer wall of the coupling body.

[0018] The inverted trapezoidal cross-section and flow-guiding grooves of the main body of the drainage channel guide water flow towards the center, where it is combined with the cutting edge structure of the rotating filter assembly to cut debris. Variable-pitch spiral blades then push the impurities into a conical debris collector, completely resolving clogging issues. The sedimentation chamber utilizes the magnetic adsorption and vibration functions of the sliding-rail sludge collection drawer to efficiently trap metal and sediment. An intelligent diverter automatically switches between drainage and storage modes based on water volume. The biological baffle of the ecological water storage tank uses the photocatalytic effect of honeycomb pores and the biodegradation of microbial carriers to purify the water. The irrigation coupler, through a dual-path orthogonal design, simultaneously supplies oxygen to the underground capillary network and the water body, ultimately achieving the resource utilization of rainwater.

Detailed Implementation

[0028] The technical solutions of 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. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] Reference Figures 1 to 8In a preferred embodiment, a landscaping drainage system includes a livestock guide channel body 100, which has an inverted trapezoidal cross-section and a sunken bottom. The channel body of the livestock guide channel body 100 has a preset slope along its length. A rotating filter cylinder assembly 200 is installed at an angle at the inlet end of the livestock guide channel 100, with its axis forming an acute angle with the bottom plane of the channel. A conical debris collector 300 is coaxially connected to the end of the rotating filter cylinder assembly 200. A settling chamber body 400 is connected to the outlet end of the livestock guide channel body 100, and a sliding rail type sludge collection drawer 410 is embedded in its bottom. An ecological water storage tank body 600 is connected to the settling chamber body 400 through an intelligent diverter 500. A biological partition 610 is vertically fixed inside the ecological water storage tank body 600. An anti-backflow overflow pipe 700 is provided on the top of the ecological water storage tank body 600, and an irrigation coupler 800 is connected to its bottom.

[0030] In some embodiments, the main body 100 of the channel includes an inverted trapezoidal channel body 101, with a flow-guiding groove formed at the junction of its side wall and the bottom of the channel; a fiber-reinforced mesh 120 is laid at the bottom of the channel body 101, a filter layer 130 is covered on the fiber-reinforced mesh 120, a purification layer 140 is provided above the filter layer 130, and capillary irrigation branch pipes 150 are embedded on both sides of the channel body 101.

[0031] See also Figure 2 In some embodiments, the capillary irrigation branch pipe 150 includes a pipe body with radially arranged micropores 151 on its wall and hydrophilic fiber channels 152 extending axially along the pipe body. Hydrophilic fiber bundles 153 are embedded in the hydrophilic fiber channels 152. In some embodiments, the hydrophilic fiber bundles 153 include a carbon fiber core 153a and a hydrogel layer 153b covering the carbon fiber core 153a.

[0032] Specifically, in some embodiments, the upper width of the inverted trapezoidal cross-section of the main body 100 is 1.8-2.2 times the lower width, and the sidewall inclination angle is 60°±5°. It is integrally formed from precast reinforced concrete or high-density polyethylene (HDPE) and embedded below the surface of the green belt, with the top flush with the ground. The inverted trapezoidal cross-section accelerates water flow convergence, and the sunken design avoids surface protrusion. The guide groove is a continuous V-shaped trench with a depth of 1 / 10 of the channel depth. The guide groove guides debris to accumulate towards the center, preventing siltation on the channel wall. The fiber-reinforced mesh 120 is a rectangular mesh structure made of basalt fiber woven mesh. It is laid flat at the bottom of the main body 100, with its upper surface flush with the bottom of the guide groove. It disperses the impact force of the water flow and prevents the bottom filter layer from being eroded and displaced. The filter layer 130 is a continuous layer with a thickness of 150-200 mm, made of volcanic rock filter media with a particle size of 5-20 mm. It is used to intercept suspended particles, and its porous structure promotes the attachment of microorganisms to form a biofilm. The purification layer 140 is a uniform layer with a thickness of 80-100 mm, made of a composite filter media of granular activated carbon (70%) and zeolite (30%). It is used to adsorb soluble pollutants such as oils and heavy metals, and zeolite ion exchange reduces water hardness. The capillary irrigation branch pipe 150 is a straight pipe with a length matching the canal length. It is horizontally embedded in the middle of both side walls of the canal body 101. The micropores 151 are used to allow seepage water to directly replenish the plant roots, and the hydrophilic fiber bundles 153 transport water to the green belt above through capillary action.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, the rotating filter cartridge assembly 200 includes a cylinder 210, the feed end of which protrudes from the inlet plane of the main body 100 of the storage channel, and a filter hole 211 is provided circumferentially; the filter hole 211 is provided with a cutting edge structure 212 at its edge, and a variable pitch spiral blade 220 is provided on the inner wall of the cylinder 210. The cylinder 210 is connected to a magnetic levitation shaft system, which includes a permanent magnet rotor 231 and a stator coil.

[0034] Specifically, the cylinder 210 is a frustum-shaped cylinder that obliquely penetrates the inlet end of the main body 100 of the storage channel. The feed end protrudes from the channel body 101. One end is connected to the pre-embedded part on the side wall of the storage channel through a flange, and the other end is sleeved with the interface of the conical debris collector 300. The inverted conical structure accelerates the water flow. The filter hole 211 is a hexagonal structure, which increases the flow area by 35% compared with the traditional round hole. The cutting edge structure 212 cuts entangled debris. Furthermore, the cutting edge structure 212 is a triangular pyramidal cutting edge. The front cutting edge forms an acute angle of 15°±2° with the normal of the outer surface of the cylinder 210, and the rear cutting edge forms an obtuse angle of 60°±5° with the inner wall of the cylinder 210. The variable-pitch spiral blade is a continuous helical surface with serrated protrusions on the edge, embedded in the inner wall of the cylinder 210. The inlet pitch P1 = 80±5mm and the outlet pitch P2 = 40±3mm. The decreasing pitch design enhances the axial propulsion force of impurities. The sharp angle design of the front cutting face efficiently cuts entangled fibrous debris (such as grass leaves and plastic bags); the obtuse angle structure of the rear cutting face prevents impurities from getting stuck at the root of the blade. The permanent magnet rotor 231 of the magnetic levitation shaft system is a neodymium iron boron permanent magnet ring, whose outer diameter is interference-fitted with the cylinder 210. The stator coil is wound with copper wire and has a silicon steel sheet laminated iron core. The magnetic levitation shaft system also includes a displacement sensor installed on the permanent magnet rotor 231. The permanent magnet rotor 231 is heat-sleeved and fixed to the journals at both ends of the cylinder 210. The stator coil is encapsulated in a waterproof cavity on the side wall of the guide channel. The displacement sensor adjusts the electromagnetic force in real time to resist water flow impact and vibration. Compared with traditional bearings, this magnetic levitation shaft system can eliminate the risk of debris getting stuck.

[0035] See also Figure 4 In some embodiments, the slide rail type sludge collection drawer 410 includes a drawer frame 414, on both sides of which roller sets 415 are provided and cooperate with the guide rail 416 at the bottom of the settling chamber body 400; a mesh plate structure 417 is installed on the drawer frame 414, and a magnetic thin film 412 is sputtered on its surface; a piezoelectric vibrator 413 is provided at the bottom of the mesh plate structure 417.

[0036] Specifically, the settling chamber body 400 is a rectangular box with a shaped bottom groove to accelerate impurity settling. It is installed directly below the outlet of the main body 100 of the diversion channel and is molded from fiberglass (FRP) using flange alignment. The fiberglass material is resistant to acid and alkali corrosion and adapts to changes in rainwater composition. The guide rail 416 is a C-shaped channel steel rail, laid along the sloping sides of the V-shaped bottom groove of the settling chamber. Nylon slips are embedded in the rail to reduce the coefficient of friction. The guide rail 416 is used to guide the precise pulling out of the sliding sludge collection drawer 410, and the nylon slips are used to achieve silent operation. The drawer frame 414 is a rectangular stainless steel square tube welded frame with an outer dimension matching the guide rail 416. The roller assembly 415 is a double-row nylon roller, set on both sides of the roller drawer frame 414, with two sets on each side, and cooperates with the groove of the guide rail 416. The mesh structure 417 is a corrugated perforated plate that fits into the limiting groove of the drawer frame 414, and is sealed with silicone strips around it to prevent leakage and increase the filtration area.

[0037] See also Figure 5 In some embodiments, the intelligent diverter 500 includes a diverting cavity 511, the pointed wedge end of which points to the outlet of the settling chamber body 400; the top of the wedge-shaped diverting cavity 511 is provided with a buoyancy slider 520; the bottom plate of the buoyancy slider 520 is connected to a double-position baffle 530, which rotatably shields the water storage passage 540 or the sewage discharge passage 550.

[0038] Specifically, the intelligent diverter 500 includes a diverting cavity 511, which is installed via a flange between the outlet of the settling chamber body 400 and the inlet of the ecological water storage tank body 600. Inside, a buoyancy slider 520 is installed. This buoyancy slider 520 is connected to a dual-position baffle 530 via a linkage mechanism, so that the lifting and lowering motion of the buoyancy slider 520 is converted into the rotational switching action of the dual-position baffle 530, thereby realizing the automatic switching between the water storage passage 540 and the sewage discharge passage 550. The linkage mechanism connects the long arm end of the L-shaped swing arm 522 through the hinge shaft 523 at the bottom of the buoyancy slider 520. The short arm end of the swing arm is connected to the adjustable connecting rod 521 through the ball joint. The end of the adjustable connecting rod 521 is threaded to the rotating arm 531 of the double-position baffle 530, which converts the vertical lifting motion of the buoyancy slider 520 into the 90° rotation switching action of the double-position baffle 530, realizing the passive automatic control of the water storage passage 540 and the sewage discharge passage 550. The buoyancy slider 520 is a cylindrical float made of closed-cell foamed polyethylene, embedded in the top groove of the diversion cavity 511. When the water level rises, buoyancy is generated, pushing the connecting rod 521 downwards. The dual-position baffle 530 is a fan-shaped stainless steel plate hinged at the intersection of the diversion channels in the diversion cavity 511. When the buoyancy slider 520 moves downwards, the dual-position baffle 530 blocks the sewage discharge passage 550; when the buoyancy slider 520 rises, the dual-position baffle 530 switches to blocking the water storage passage 540. The water storage passage 540 leads to the main body of the ecological water storage tank 600, opening during low flow periods to allow rainwater to be introduced into the storage tank for purification. The sewage discharge passage 550 is directly connected to the municipal drainage network, automatically opening during heavy rain to directly discharge excess rainwater and prevent flooding.

[0039] See also Figure 6 In some embodiments, the biological partition 610 includes: a partition body having honeycomb pores 611 arrayed on its top, and a photocatalytic coating 612 loaded on the pore walls;

[0040] And a biological packing basket 613 suspended at the bottom of the partition body, which is filled with a slow-release microbial carrier 614.

[0041] Specifically, the main body 600 of the ecological water storage tank is a vertical cylindrical tank, formed by rolling and welding stainless steel, and fixed to a concrete foundation with anchor bolts. Its lower side wall connects to the water storage passage 540 of the intelligent diverter 500, an irrigation coupler 800 is installed at the bottom, and an anti-backflow overflow pipe 700 is installed at the top. A biological baffle 610 fixed inside the tank divides the water storage area into a primary sedimentation zone 620 and a secondary clear water zone 630, achieving step-by-step purification of rainwater. The outer edge of the biological baffle 610 is fixed to a protrusion on the inner wall of the tank with clamps. The biological packing basket 613 is a rectangular hollow basket, suspended from the bottom of the baffle body by stainless steel hooks. Honeycomb holes 611 are used to increase the flow area. The photocatalytic coating 612 degrades organic matter under ultraviolet light. The biological packing basket 613 carries a microbial carrier 614 for biological purification. Furthermore, the honeycomb pores 611 are arranged in a regular hexagonal array with an open area ratio ≥65%. The pore walls are roughened by sandblasting before being loaded with a photocatalytic coating 612. This photocatalytic coating 612 is formed by curing a titanium dioxide-graphene composite sol at 150℃, with a thickness of 10-15μm. It covers all pore wall surfaces and functions to excite strong oxidizing free radicals under natural light, decomposing organic pollutants in rainwater, achieving a COD removal rate ≥40%. The microbial carrier 614 is porous ceramic granules, filling 80% of the basket volume. The ceramic granule carrier has a huge specific surface area (≥800m²). 2 / m 3 It promotes microbial attachment and decomposes nitrogen and phosphorus pollutants in rainwater, with a total nitrogen removal rate of ≥35%. During operation, rainwater enters the primary sedimentation zone 620 through the water storage channel 540, where suspended solids settle naturally. As the water flows through the honeycomb holes 611, the photocatalytic coating 612 decomposes dissolved organic matter. The water flows through the biological packing basket 613, where the microbial carrier 614 degrades nitrogen and phosphorus pollutants. The purified water is stored in the secondary clear water zone 630 and then output through the irrigation coupler 800.

[0042] like Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the irrigation coupler 800 includes a coupling body 801, which is arranged vertically along the axis and has an inlet flange 802 connected to the top, an irrigation flange 803 connected to the bottom, and an aeration flange 804 connected to the side wall.

[0043] The inlet flange 802 is connected to the inlet end of the main irrigation pipe 810, and the main irrigation pipe 810 extends through the irrigation flange 803 to the underground pipe network; the aeration flange 804 is fixedly connected to the jet oxygenation branch pipe 820, and the end of the jet oxygenation branch pipe 820 is provided with a Venturi nozzle 821 that extends into the middle of the ecological water storage tank body 600; the main irrigation pipe 810 is spatially orthogonal to the jet oxygenation branch pipe 820 at 90° in the inner cavity of the coupling body 801; a first solenoid valve 831 is provided on the main irrigation pipe 810 near the inlet flange 802, and a second solenoid valve 832 is provided on the jet oxygenation branch pipe 820 near the Venturi nozzle 821; a control circuit board is fixedly installed on the outer wall of the coupling body 801.

[0044] Specifically, the coupling body 801 is a cylindrical stainless steel casting, vertically installed at the bottom outlet of the ecological water storage tank body 600. Its top has an inlet flange 802 connecting to the water outlet of the storage tank, and its bottom has an irrigation flange 803 connecting to the underground pipe network. An aeration flange 804 is welded at a 45° angle to the side wall. The three flanges are spatially orthogonally distributed, forming a dual-channel fluid distribution core. The main irrigation pipe 810 is a straight-through stainless steel pipe, vertically penetrating the coupling body 801, connected to the inlet flange 802 at the top and the irrigation flange 803 at the bottom. The jet aeration branch pipe 820 is an L-shaped copper pipe, with its long arm horizontally connected to the aeration flange 804 and its short arm extending vertically into the ecological water storage tank body 600. The Venturi nozzle 821 is threadedly connected to the end of the jet aeration branch pipe 820, utilizing the water flow velocity to generate negative pressure at the throat, drawing in air to form a gas-water mixed jet. The first solenoid valve 831 is a normally closed direct-acting solenoid valve, located directly below the inlet flange 802, and is used to control the on / off state of the main irrigation system. The second solenoid valve 832 is a normally open angle seat valve, located near the Venturi nozzle 821, and is used to adjust the aeration intensity. The control circuit board is a waterproof housing, bolted to the outer wall of the coupling body 801, and connected to both the first solenoid valve 831 and the second solenoid valve 832. It is used to receive humidity signals and coordinate the switching between irrigation and aeration modes.

[0045] Working principle:

[0046] Before starting work: Empty the impurities from the sliding rail type sludge collection drawer 410, and check whether the water level in the main body of the ecological water storage tank 600 is lower than the inlet of the anti-backflow overflow pipe 700. Confirm that the magnetic levitation shaft system of the rotating filter cartridge assembly 200 is powered on and performs a normal self-test, and that the first solenoid valve 831 and the second solenoid valve 832 of the irrigation coupler 800 are in the closed state.

[0047] During operation: Rainwater flows into the main body 100 of the diversion and storage channel, and converges towards the center through the diversion groove; the water flow impacts the rotating filter cartridge assembly 200, driving the cylinder 210 to rotate, the cutting edge structure 212 cuts entangled debris, and the variable pitch spiral blade 220 pushes the impurities axially into the conical debris collector 300; the pre-filtered water flows into the main body 400 of the settling chamber, where the magnetic mesh plate 417 adsorbs metallic impurities, and the piezoelectric vibrator 413 prevents silt from caking. The intelligent diverter 500 automatically controls the flow according to the water volume: at low flow rates, the water storage passage 540 is opened, and the water flows into the main body 600 of the ecological water storage tank; at high flow rates, it switches to the sewage discharge passage 550, and excess rainwater is discharged into the municipal pipe network; the water entering the water storage tank passes through the biological partition 610: the honeycomb holes 611 intercept suspended solids, the photocatalytic coating 612 decomposes organic matter, and the microbial carrier 614 degrades nitrogen and phosphorus pollutants. When the first solenoid valve 831 of the irrigation coupler 800 is opened, clean water is transported to the underground capillary network through the main irrigation pipe 810, and the hydrophilic fiber bundle 153 slowly releases the water to the plant roots; when the second solenoid valve 832 is activated, the Venturi nozzle 821 of the jet oxygenation branch pipe 820 injects air into the water storage tank to increase the dissolved oxygen content of the water.

[0048] After work: Regularly remove the sliding rail sludge collection tray 410 to clean the adsorbed impurities; check the activity of the microbial carrier 614 in the biological packing basket 613 and replenish the bacterial agent as needed; after the rainy season, empty the water storage tank and close the water storage passage of the intelligent diverter 500.
