Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting technology, and more specifically to a permeable rockery base with a rainwater harvesting system. Background Technology

[0002] The rainwater harvesting system is deeply integrated into the rockery structure, with water channels and filter layers embedded in the stone crevices. After purification, the rainwater is stored in a reservoir at the base of the rockery. Combined with a modular planting pit design, drought-resistant and barren-tolerant native rock-growing plants are selected to construct an ecological cycle system of "rainwater harvesting-purification-irrigation," thereby enhancing the ecological service functions of the rockery landscape.

[0003] Artificial rockeries can be constructed either within a pond or on the ground. If built within a pond, rainwater can be collected during the rainy season and pumped to the rockery to irrigate drought-resistant plants. If built on the ground, however, irrigation relies solely on tap water. The quality of tap water is incompatible with the natural growth needs of plants; residual free chlorine (Cl2) and hypochlorous acid (HClO) can easily cause plants to yellow and die. Furthermore, collecting rainwater during heavy rains not only provides a large supply of clean water but also alleviates drainage pressure on irrigation canals, significantly conserving water resources.

[0004] Therefore, it is necessary to design a permeable rockery base with a rainwater collection system that can collect rainwater on the ground. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a permeable rockery base with a rainwater harvesting system, capable of collecting rainwater on the ground.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a permeable rockery base with a rainwater collection system, including a cement floor and a water tank. A ring-shaped waterway, a sewer, and a water storage tank are provided on the cement floor. The ring-shaped waterway is connected to the water storage tank through an internal waterway and to the sewer through an external waterway. An edge cement slab is provided at the bottom of the rockery, which covers the top of the water storage tank and is fixedly connected to the cement floor. The edge cement slab is in contact with the bottom of the water storage tank through a steel reinforcement frame. Multiple internal waterways near the front of the rockery are provided with an internal flow gate 1, and multiple internal waterways near the back of the rockery are provided with an internal flow gate 2. Sewer gates are provided in multiple external waterways. A lower groove is provided at the bottom of the water storage tank, and a water pump draws water from the lower groove into the water tank.

[0007] Preferably, the inner flow gate includes a gate plate, a rotating rod, a float block, two side plates, and a filter screen. The two side plates are fitted together on both sides of the inner flow channel. The tail end of the rotating rod is rotatably connected to the inner flow channel, and the head end of the rotating rod is rotatably connected to the float block. The gate plate is vertically slidably installed between the two side plates. A sliding post is provided on the side of the gate plate, which is inserted into the rotating rod. An oblong hole is provided on the rotating rod for the sliding post to slide. A pad block is fixedly provided at the bottom of the float block to contact the bottom of the annular waterway. A lower sealing plate is provided on the side of the gate plate. The upper and lower sealing plates are used to seal the gap between the gate plate and the bottom of the side plate. The upper sealing plate is used to seal the gap between the gate plate and the top of the side plate. When the pad block contacts the bottom of the inner waterway, the bottom of the upper sealing plate contacts the rotating rod, and the top of the lower sealing plate contacts the rotating rod. The filter screen is fixedly installed between the two side plates. The filter screen is used to filter the gap between the gate plate and the inner waterway after the gate plate is lifted up. In rainy weather, the sewer gate is closed. Through the buoyancy of the floating block, the inner waterway gate 1 and the inner waterway gate 2 are opened.

[0008] Preferably, a sealing cover is provided between the two side plates for sealing.

[0009] Preferably, the lower sealing plate is provided with a slider on its side, and the inner sides of the two side plates are provided with a strip groove for the slider to slide vertically.

[0010] Preferably, a tail plate is fixedly provided at the tail of the two side plates, a filter screen is fixedly provided on one side of the tail plate, and an outward flange is provided at the head of the side plate.

[0011] Preferably, the second inland flow gate has the same structure as the first inland flow gate. The second inland flow gate includes a gate plate, a cover plate that can slide vertically in the middle of the gate plate, a clearance groove for vertical sliding of the cover plate, a water passage hole 1 on the cover plate, and a water passage hole 2 penetrating the gate plate. When the water passage hole 1 contacts the bottom of the clearance groove, the water passage hole 1 and the water passage hole 2 are connected. The second gate also includes a downward pressure rod, which is rotatably mounted on the side plate of the second inland flow gate via a rotating seat. A sliding column 2 is fixedly installed on the top of the cover plate. One end of the downward pressure rod is slidably connected to the sliding column 2. The downward pressure rod has an oblong sliding hole for sliding of the sliding column 2. The other end of the downward pressure rod is located directly above the gate plate. When the gate plate of the inland flow gate is pulled upward, it drives the downward pressure rod to press downward. Preferably, the cover plate has a retaining strip on its side, and the gate plate has a strip groove for the retaining strip to slide vertically.

[0012] Preferably, the sewer gate includes an electric push rod, the gate plate is fixedly connected to the output end of the electric push rod, and the electric push rod is fixedly installed on the cement ground by a mounting bracket.

[0013] Preferably, a seepage hole is provided at the bottom of the lower groove, and the seepage hole is connected to the mud.

[0014] Preferably, plastic turf is laid on the top of the cement cover and on the cement slabs along the edges.

[0015] The beneficial effects of this invention are as follows: a permeable rockery base with a rainwater harvesting system can collect rainwater on the ground and filter it during heavy rain. It will not absorb rainwater containing large amounts of dirt during light rain or the initial stages of a heavy downpour.

[0016] Since multiple inflow gates (gate 1 and gate 2) need to be designed and opened using buoyancy, there is no need to design electrical control components or install piping, which saves on the cost of inflow gates 1 and 2 and avoids the risk of electric shock due to damaged wiring in rainy weather. Furthermore, because there is no wiring, inflow gates 1 and 2 are easier to remove for maintenance and cleaning. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments based on the embodiments of the present invention obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: This invention provides a permeable rockery base with a rainwater harvesting system, such as... Figure 1-14As shown, the structure includes a cement floor 1 and a water tank 7. A circular waterway 1a, a sewer 1b, and a water storage tank 1c are provided on the cement floor 1. The circular waterway 1a is connected to the water storage tank 1c via an internal waterway 1d, and the circular waterway 1a is connected to the sewer 1b via an external waterway 1e. A perimeter cement slab 3a is provided at the bottom of the artificial hill 3, covering the top of the water storage tank 1c and fixedly connected to the cement floor 1. Cement slab 3a contacts the bottom of reservoir 1c via steel reinforcement frame 3b. Multiple internal waterways 1d near the front of the artificial hill 3 are equipped with internal flow gates 1-4, and multiple internal waterways 1d near the back of the artificial hill 3 are equipped with internal flow gates 2-5. Multiple external waterways 1e are equipped with sewer gates 6. A recessed groove 1c1 is located at the bottom of reservoir 1c, and water tank 7 is pumped into the water tank 7 by a water pump 8. Internal flow gates 2-5 have a similar overall structure to internal flow gates 1-4, but with a difference: when sewer gates 6 are fully open, internal flow gates 2-5 are in an unfiltered open state, allowing water to be introduced into reservoir 1c more quickly. Furthermore, the sewer gates 6 are located on the back of the artificial hill 3, with no protruding structure on the front, making it more aesthetically pleasing. Cement covers 2 are installed on the annular waterway 1a, sewer 1b, internal waterways 1d, and external waterways 1e.

[0035] During light rain, the sewer gate 6 is open, while the inflow gate 1 4 and the inflow gate 2 5 are closed. At this time, less rainwater enters the annular waterway 1a, and most of it carries dirt from the mountain. This type of rainwater is not suitable for storage or irrigation.

[0036] During heavy rain, the sewer gate 6 is closed, while the inner flow gates 4 and 5 are open. With abundant rainfall, the rainwater, by closing the sewer gate 6, does not flow into the sewer 1b but instead flows along the inner flow channel 1d to the reservoir 1c. The water pump 8 then pumps the rainwater from the lower groove 1c1 into the water tank 7 for storage. When irrigation is needed, the rainwater in the water tank 7 can be pumped out to irrigate the plants. Furthermore, the water tank 7 is connected to a tap water pipe, allowing for water replenishment during periods of drought in autumn and winter. A sliding door is located on the back of the artificial hill 3 for easy access for maintenance and cleaning.

[0037] It should be noted that each internal flow gate 5 and the sewer gate 6 form a group of structures, and the spacing between each group of structures is determined according to the mountain structure. Figure 4 The spacing in the diagram is only to indicate the possibility of multiple structures.

[0038] Because the initial rainwater carries a lot of dirt during heavy rain, this dirt cannot directly enter the reservoir 1c; at the same time, there are many internal flow gates 1-4 and 2-5, making electrical control impossible. Therefore, it is necessary to simultaneously open internal flow gates 1-4 and 2-5 when the sewer gate 6 is closed. For this purpose, internal flow gate 1-4 includes a gate plate 4a, a rotating rod 4b, a float block 4c, two side plates 4d, and a filter screen 4f. The two side plates 4d are fitted together on both sides of the internal flow channel 1d. The tail end of the rotating rod 4b is rotatably connected to the internal flow channel 1d, and the head end of the rotating rod 4b is rotatably connected to the float block 4c. The gate plate 4a is vertically slidable between the two side plates 4d. A sliding post 4a4 is provided on the side of the gate plate 4a, which is inserted into the rotating rod 4b. The rotating rod 4b has a waist-shaped hole for the sliding post 4a4 to slide through. Figure 9 The oblong hole can be seen, and because the width of the oblong hole is small, it can meet the movement requirements of the sliding column 4a4. The bottom of the floating block 4c is fixedly provided with a pad 4c1 that contacts the bottom of the annular waterway 1a. The side of the gate 4a is provided with a lower sealing plate 4a1 and an upper sealing plate 4a2. The lower sealing plate 4a1 is used to seal the gap between the bottom of the gate 4a and the side plate 4d, and the upper sealing plate 4a2 is used to seal the gap between the top of the gate 4a and the side plate 4d. When the pad 4c1 contacts the bottom of the inner waterway 1d, the bottom of the upper sealing plate 4a2 contacts the rotating rod 4b, and the top of the lower sealing plate 4a1 contacts the rotating rod 4b. The filter screen 4f is fixedly installed between the two side plates 4d. The filter screen 4f is used to filter the gap X between the gate 4a and the inner waterway 1d after the gate 4a is raised. During heavy rain, the sewer gate 6 is closed. The buoyancy of the floating block 4c opens the inner flow gates 4 and 5. During light rain, the floating block 4c is raised by the pad block 4c1, and the sewer gate 6 is open, preventing rainwater from lifting the floating block 4c. However, during heavy rain, although the sewer gate 6 remains open initially, the raised floating block 4c by the pad block 4c1 prevents the gate plate 4a from being lifted by rainwater, thus preventing rainwater from flowing into the reservoir 1c along the inner flow channel 1d and preventing dirt from entering the reservoir 1c.

[0039] After half an hour of continuous rainfall, the sewer gate 6 is closed. At this time, the rainwater will push the floating block 4c upward along the M1 direction, which in turn will drive the rotating rod 4b to rotate along the S direction; the rotating rod 4b drives the gate plate 4a to slide upward through the sliding column 4a4, so that a gap X is formed at the top of the gate plate 4a. Before the rotating rod 4b rotates, the sealing effect of the lower sealing plate 4a1 and the upper sealing plate 4a2 can prevent rainwater from flowing directly into the water storage tank 1c through the gap between the gate plate 4a and the side plate 4d.

[0040] After the sewer gate 6 is closed, the buoyancy of the floating block 4c can open the inner flow gate 4. The inner flow gate 5 opens using the same principle, so multiple inner flow gates 4 and 5 can be set. When the floating block 4c floats upward, its top contacts the cement cover plate 2, achieving overall leveling and limiting of the floating block 4c.

[0041] A sealing cover plate 4j is provided between the two side plates 4d for sealing. Since there is a gap between the upper sealing plate 4a2 and the edge cement plate 3a, the gap can be sealed by the sealing cover plate 4j.

[0042] A slider 4a3 is provided on the side of the lower sealing plate 4a1, and a strip groove 4d1 is provided on the inner side of the two side plates 4d for the slider 4a3 to slide vertically. Through the action of the gate plate 4a, when the slider 4a3 slides vertically upward, it can be guided by the strip groove 4d1 to ensure that the gate plate 4a can slide vertically.

[0043] Tail plates 4e are fixedly installed at the rear of the two side plates 4d, and a second filter screen 4h is fixedly installed on one side of the tail plate 4e. Secondary filtration is performed by the second filter screen 4h to ensure the cleanliness of the water entering the water storage tank 1c. The front end of the side plate 4d is provided with an outward-facing flange 4k. The flange 4k limits the position of the side plate 4d, allowing it to be quickly pulled upwards when cleaning the first filter screen 4f and the second filter screen 4h is required.

[0044] When the annular waterway 1a is overflowing, the sewer gate 6 must be opened to prevent water from overflowing from the top of the cement cover 2. Simultaneously, the inner flow gate 2 5 is switched to unfiltered mode, allowing water to flow more quickly into the reservoir 1c. For this purpose, the inner flow gate 2 5 has the same structure as the inner flow gate 1 4. The inner flow gate 2 5 includes a gate plate 2 5a, with a vertically sliding cover plate 5a1 in the middle. The gate plate 2 5a has a clearance groove for vertical sliding of the cover plate 5a1. The cover plate 5a1 has a water passage hole 1 5a2, and the gate plate 2 5a has a water passage hole 2 5a3 penetrating through it. When the water passage hole 1 5a2 contacts the bottom of the clearance groove, the water passage hole 1 5a2 and the water passage hole 2 5a3 are connected. The gate 5a also includes a pressing rod 5c, which is rotatably mounted on the side plate of the inner flow gate 5 via a rotating seat 5b. A sliding column 5d is fixedly installed on the top of the cover plate 5a1. One end of the pressing rod 5c is slidably connected to the sliding column 5d. The pressing rod 5c has an oblong sliding hole for the sliding column 5d to slide. The other end of the pressing rod 5c is located directly above the gate 6a. When the gate 6a of the lower channel gate 6 is pulled upward, it drives the pressing rod 5c to press downward.

[0045] A retaining strip 5a4 is provided on the side of the cover plate 5a1, and a strip-shaped groove 5a5 is provided on the gate plate 5a for the retaining strip 5a4 to slide vertically. Through the cooperation of the retaining strip 5a4 and the strip-shaped groove 5a5, the cover plate 5a1 can be slidably connected to the gate plate 5a. Figure 12 As shown, when the sluice gate 6a is closed, the downward pressure rod 5c is pulled by gravity, causing the top of the locking strip 5a4 to contact the top of the second strip groove 5a5. At this time, the cover plate 5a1 and the second sluice gate 5a are misaligned, and the first water passage hole 5a2 and the second water passage hole 5a3 cannot communicate, so water cannot flow between them. At the same time, the floating block 4c is driven by buoyancy to move the second sluice gate 5a upward, at which time the first filter screen 4f can allow water to flow through.

[0046] When the annular waterway 1a overflows, the sewer gate 6 needs to be opened. As the gate 6a moves upward to open, it pushes the downward pressure rod 5c to rotate along the rotating seat 5b, thus pressing down on the cover plate 5a1. During this movement, the retaining strip 5a4 contacts the bottom of the second strip chute 5a5 and continues to push downward, causing the cover plate 5a1 to push the second gate 5a downward, closing the filter screen 4f. Simultaneously, because the retaining strip 5a4 contacts the bottom of the second strip chute 5a5, the first water passage hole 5a2 and the second water passage hole 5a3 are connected, allowing rainwater to flow through them. This means the internal flow gate 5 switches to an unfiltered mode, allowing water to enter the reservoir 1c more quickly. By opening the sewer gate 6 and switching the internal flow gate 5 to an unfiltered mode, the liquid level in the annular waterway 1a can be quickly reduced.

[0047] It should be noted that the internal flow gate 25 can switch to the unfiltered mode, partly because the mountain has been washed for a long time and the rainwater does not carry much dirt; at the same time, when the annular waterway 1a is full, the dirt content in the water is also low, so it can switch to this mode.

[0048] The sewer gate 6 includes an electric push rod 6c. A sluice gate 6a is fixedly connected to the output end of the electric push rod 6c. The electric push rod 6c is fixedly installed on the cement ground 1 via a mounting bracket 6b. By controlling the operation of the electric push rod 6c, it can pull the sluice gate 6a upward, allowing rainwater from the annular waterway 1a to enter the sewer 1b along the outflow channel 1e.

[0049] A seepage hole 1c2 is provided at the bottom of the lower groove 1c1, and the seepage hole 1c2 is connected to the mud. Through the function of the seepage hole 1c2, when a small amount of rainwater accumulates at the bottom of the lower groove 1c1, the rainwater can seep downwards along the lower groove 1c1, thereby preventing the interior of the artificial mountain 3 from becoming too damp.

[0050] Plastic turf is laid on the top of the cement cover 2 and on the cement slab 3a along the edge. The plastic turf can be used to filter out large pieces of garbage such as branches and plastic bags.

[0051] In use, the permeable rockery base with rainwater collection system allows rainwater to infiltrate into the annular waterway 1a, and after being filtered by filter screen 4f and filter screen 4h, it flows into the reservoir 1c. During light rain, the sewer gate 6 is open, and because the rainfall is small, it cannot lift the floating block 4c upwards, so the inflow gate 4 and inflow gate 5 remain closed. During heavy rain, the sewer gate 6 is closed, and because the rainfall is large, the rainwater lifts the floating block 4c upwards, and the inflow gate 4 and inflow gate 5 open accordingly, allowing the rainwater to flow into the reservoir 1c. When the rainwater overflows from the reservoir 1c, the sewer gate 6 opens, and at the same time, the inflow gate 5 switches to the unfiltered mode.

[0052] Therefore, a permeable artificial mountain base with a rainwater harvesting system needs to be designed to collect rainwater from the ground and filter it during heavy rain. It should not absorb rainwater containing large amounts of dirt during light rain or the initial stages of a downpour.

[0053] Since multiple internal flow gates (1-4 and 2-5) need to be designed and use a buoyancy-based opening method, there is no need to design electrical control components or install pipeline wiring, which saves on the cost of internal flow gates 1-4 and 2-5, and avoids the risk of electric shock due to damage to the wiring caused by rain. In addition, because there is no wiring, internal flow gates 1-4 and 2-5 are easier to remove for maintenance and cleaning.

[0054] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
