Technical Field

[0001] The utility model relates to the technical field of planting pools, in particular to a technology for collecting and utilizing rainwater in planting pools. Background Art

[0002] Planting pools are artificial structures used in urban greening and gardening. They are used to grow plants and provide the basic space required for plant growth. They are widely used in road greening, squares, parks, commercial centers and other occasions.

[0003] The existing planting pools make use of rainwater in a relatively simple way. After the rainwater enters the planting pool, except for a part being absorbed by the soil in the planting pool, most of the rainwater directly penetrates into the ground, replenishing groundwater resources and reducing surface runoff.

[0004] The design objectives of this utility model are:

[0005] The first goal is to extend the soil moisture retention time in the planting pool, thereby improving rainwater utilization and reducing irrigation water consumption, irrigation frequency and irrigation costs.

[0006] The secondary goal is to filter rainwater and improve the quality of water supplied to the soil in the planter ponds.

[0007] To achieve the above objectives, the specific design ideas of the utility model are as follows:

[0008] 1. Provide water storage for the planting pool, prolong the time for rainwater to replenish moisture for the soil in the planting pool, so that most of the rainwater can be used by plants. Through structural design, the stored rainwater can evenly penetrate into the soil of the planting pool.

[0009] 2. Provide filtering function for the planting pool, thereby preventing leaves, paper and other debris from entering, improving water quality and reducing the impact of harmful substances on plants.

[0010] 3. Through structural design, the ability to slowly release rainwater into the soil of the planting pool is further improved, the soil of the planting pool is kept moist for a longer period of time after precipitation, and the number of irrigation times and the amount of water used for irrigation are reduced. Utility Model Content

[0011] The utility model aims to provide a uniformly infiltrated water-storing planting pool, which has a water-storing function and the stored rainwater can infiltrate the soil of the planting pool relatively uniformly.

[0012] To achieve the above-mentioned purpose, the utility model provides a uniformly infiltrated water storage planting pool, including a box body, a planting cavity with an open top in the middle of the box body, and is characterized in that: the bottom wall of the planting cavity is made of permeable material, the bottom wall of the planting cavity is higher than the inner wall of the box body, and a water seepage cavity is formed between the two; an annular cavity is provided between the outer wall of the planting cavity and the inner wall of the box body, a steel grate plate is provided on the top of the annular cavity, and a pebble layer is laid on the grate plate; the horizontal cross-sections of the pebble layer and the grate plate are both annular in shape matching the annular cavity; the inner end of the grate plate is fixedly connected to the outer wall of the planting cavity, the outer end of the grate plate is fixedly connected to the inner wall of the box body, and the bottom of the annular cavity is connected to the water seepage cavity.

[0013] A lower supporting orifice plate is horizontally arranged at the middle and lower part of the annular cavity in the vertical direction, a filter material layer is laid on the lower supporting orifice plate, an upper supporting orifice plate is arranged above the filter material layer, and a fine sand and gravel layer is laid on the upper supporting orifice plate;

[0014] The lower supporting orifice plate and the upper supporting orifice plate are both fixedly connected inwardly to the outer wall of the planting cavity and are both fixedly connected outwardly to the inner wall of the box body; the fine sand and gravel layer and the grate plate form a primary filtering and settling chamber, and the annular cavity below the lower supporting orifice plate forms a secondary filtering and settling chamber.

[0015] A hydrogel bead layer is arranged at the bottom of the secondary filtering sedimentation chamber.

[0016] The bottom of the box body is surrounded by a ring-shaped retaining groove on the outside, and the top of the retaining groove is provided with a water-permeable and breathable plate. The side wall of the secondary filtration and sedimentation chamber is provided with a water hole connected to the retaining groove. The water hole is located at the top of the secondary filtration and sedimentation chamber and is provided with multiple holes; the bottom of the side wall of the secondary filtration and sedimentation chamber is provided with a micro-pressure one-way valve, which is used to allow the water in the retaining groove to flow unidirectionally into the secondary filtration and sedimentation chamber.

[0017] The utility model has the following advantages:

[0018] With the structure of the utility model, the annular cavity surrounding the planting cavity is used to store rainwater, and the stored rainwater can enter the water seepage cavity evenly along the circumferential direction, and then penetrate upward from the water seepage cavity through the bottom wall of the planting cavity to the soil of the planting pool. The water seepage effect on the horizontal cross section of the soil of the planting pool is uniform, so the soil of the planting pool is evenly hydrated, which is more conducive to plant absorption and growth. By providing a water storage function, the utility model prolongs the time for rainwater to replenish moisture for the soil of the planting pool, reduces the number of irrigations and the amount of water used for irrigation, saves water resources and reduces irrigation costs.

[0019] The upper supporting perforated plate, the lower supporting perforated plate, the fine sand and gravel layer and the filter material layer constitute the middle structure, which divides the annular cavity into a primary filtering sedimentation cavity and a secondary filtering sedimentation cavity, providing two filtering sedimentation processes. On the basis of intercepting larger impurities by the pebble layer, finer impurities and harmful chemicals are filtered through the fine sand and gravel layer and the filter material layer, thereby further purifying the water quality.

[0020] Hydrogel beads are spheres made of hydrogel materials, which have the characteristics of high water absorption and excellent adsorption capacity. They can absorb pollutants such as heavy metal ions in water and significantly improve water quality. The hydrogel bead layer can not only absorb pollutants to improve the purification effect, but also regulate the amount of water, extend the time of water supply to the soil of the planting pool, keep the soil of the planting pool moist, and reduce the amount of water used for irrigation and the number of irrigation times.

[0021] The retaining groove provides additional water storage, further extending the time that the soil in the planting cavity is kept moist, reducing the number of watering times and the amount of water used for watering.

[0022] In summary, the utility model intercepts larger impurities, such as leaves, paper, larger mud and other solid impurities, through the pebble layer, to prevent these impurities from entering the primary filtering and settling chamber of the annular cavity. A primary settling process occurs in the primary filtering and settling chamber. Then, smaller particles and suspended matter in the water are filtered through the fine sand and stone layer to further purify the water quality, and a secondary settling process occurs, reducing the impact of harmful substances on the stored water and plants, which not only makes more full use of rainwater but also is more conducive to the growth of plants in the planting pool. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the main cross-sectional structure of the utility model;

[0024] Figure 2 It is a top view of the utility model. DETAILED DESCRIPTION

[0025] like Figure 1 and Figure 2 As shown, the utility model discloses a uniformly infiltrated water storage planting pool, comprising a box body 1, a planting cavity 2 with an open top is arranged in the middle of the box body 1, the horizontal cross section of the planting cavity 2 can be circular or square, the bottom wall of the planting cavity 2 is made of a water-permeable material, the bottom wall of the planting cavity 2 is higher than the inner wall of the box body 1, and a water seepage cavity 3 is formed between the two;

[0026] The direction pointing to the center of the implant cavity 2 is considered inward, and the opposite direction is considered outward.

[0027] There is an annular cavity (which can be a circular annular cavity or a square annular cavity) between the outer wall of the planting cavity 2 and the inner wall of the box body 1, and a steel grate plate 4 is provided on the top of the annular cavity, and a pebble layer 5 is laid on the grate plate 4; the horizontal cross-sections of the pebble layer 5 and the grate plate 4 are both annular in shape matching the annular cavity; the inner end of the grate plate 4 is fixedly connected to the outer wall of the planting cavity 2, and the outer end of the grate plate 4 is fixedly connected to the inner wall of the box body 1, and the bottom of the annular cavity is connected to the water seepage cavity 3. Figure 1 The pebble layer 5 with a straight section line in the middle represents a vertical section of the pebble layer 5. Figure 1The other part of the middle cobblestone layer 5 (the part of the cobblestone layer 5 represented by the irregular circle) is the uncut inclined surface of the cobblestone layer 5. The cobblestone layer is arranged to be high outside and low inside and is used to guide water to the planting cavity 2. The bottom wall of the planting cavity 2 is preferably made of permeable concrete or permeable bricks.

[0028] With the structure of the utility model, the annular cavity surrounding the planting cavity 2 is used to store rainwater, and the stored rainwater can enter the water seepage cavity 3 evenly along the circumferential direction, and then penetrate upward from the water seepage cavity 3 through the bottom wall of the planting cavity 2 to the soil of the planting pool. The water seepage effect on the horizontal cross section of the soil of the planting pool is uniform, so the soil of the planting pool is evenly hydrated, which is more conducive to plant absorption and growth. By providing a water storage function, the utility model prolongs the time for rainwater to replenish moisture for the soil of the planting pool, reduces the number of irrigations and the amount of water used for irrigation, saves water resources and reduces irrigation costs.

[0029] A lower supporting orifice plate 6 is horizontally arranged at the middle and lower part of the annular cavity in the vertical direction, a filter material layer 7 (the filter material layer 7 adopts an activated carbon filter layer or an anthracite filter layer) is laid on the lower supporting orifice plate 6, an upper supporting orifice plate 8 is arranged above the filter material layer 7, and a fine sand and gravel layer 9 is laid on the upper supporting orifice plate 8;

[0030] The lower supporting orifice plate 6 and the upper supporting orifice plate 8 are both fixedly connected inwardly to the outer wall of the planting cavity 2 and are both fixedly connected outwardly to the inner wall of the box body 1; the fine sand and gravel layer 9 and the grate plate 4 form a primary filtering and settling chamber 10, and the annular cavity below the lower supporting orifice plate 6 forms a secondary filtering and settling chamber 11.

[0031] The upper supporting orifice plate 8 and the lower supporting orifice plate 6 are preferably made of ceramsite (ie, ceramsite plates), which have both good filtering and supporting effects.

[0032] The upper supporting perforated plate 8, the lower supporting perforated plate 6, the fine sand and gravel layer 9 and the filter material layer 7 constitute an intermediate structure, which divides the annular cavity into a primary filtering and settling chamber 10 and a secondary filtering and settling chamber 11, providing two filtering and settling processes. On the basis of intercepting larger impurities by the pebble layer 5, finer impurities and harmful chemicals are filtered through the fine sand and gravel layer 9 and the filter material layer 7, thereby further purifying the water quality.

[0033] A hydrogel bead layer 12 is provided at the bottom of the secondary filtration sedimentation chamber 11. The hydrogel beads are spheres made of hydrogel materials, and have the characteristics of high water absorption and excellent adsorption capacity. They can adsorb pollutants such as heavy metal ions in water, and significantly improve the water quality. The hydrogel bead layer 12 can not only adsorb pollutants to improve the purification effect, but also regulate the amount of water, prolong the time of supplying water to the soil of the planting pool and keeping the soil of the planting pool moist, and reduce the amount of water used for irrigation and the number of irrigation times. Specifically, during rainfall, the hydrogel bead layer 12 absorbs a large amount of water. After the water in the secondary filtration sedimentation chamber 11 is used up, the water is gradually released in the process of gradual drying and infiltrated into the planting pool through the water infiltration chamber 3, thereby extending the time of keeping the soil of the planting pool moist through the slow release effect.

[0034] The bottom of the box body 1 is surrounded by a ring-shaped enclosure groove 13, and the top of the enclosure groove 13 has a water-permeable and air-permeable plate 14. The side wall of the secondary filtration and sedimentation chamber 11 is provided with a water hole 15 connected to the enclosure groove 13. The water hole 15 is located at the top of the secondary filtration and sedimentation chamber 11 and is provided with multiple holes; Figure 1 In the embodiment, a plurality of water holes 15 are arranged at intervals in front and behind the horizontal position where the water hole 15 is located, but Figure 1 There is only one water hole 15 on both sides. Figure 1 vertical section.

[0035] A micro-pressure one-way valve 16 is provided at the bottom of the side wall of the secondary filtration and sedimentation chamber 11, and the micro-pressure one-way valve 16 is used to allow the water in the enclosure 13 to flow unidirectionally into the secondary filtration and sedimentation chamber 11. The enclosure 13 provides an additional water storage function, further prolonging the time for keeping the soil of the planting chamber 2 moist, and reducing the number of irrigations and the amount of water used for irrigation.

[0036] The pebble layer 5 is exposed on the ground, so there may be leaves, discarded paper and even plastic sheets on it. The pebble layer 5 can block these debris and is difficult to be blocked by these debris, so it is very suitable as the top filter material of the utility model. In use, rainwater falls on the pebble layer 5, passes through the grate plate 4, the primary filtration sedimentation chamber 10, the fine sand and stone layer 9 and the filter material layer 7 downward into the secondary filtration sedimentation chamber 11, passes through the hydrogel bead layer 12 and enters the water seepage chamber 3, and then penetrates upward from the water seepage chamber 3 through the bottom wall of the planting chamber 2 (permeable concrete or permeable brick) and enters the soil of the planting chamber 2 to supply water to the plants.

[0037] When it rains, when the water in the secondary filtration sedimentation chamber 11 is full, the water after two stages of filtration will overflow into the retaining groove 13 through the water hole 15 and be stored in the retaining groove 13. In this process, the water level in the secondary filtration sedimentation chamber 11 is higher than the water level in the retaining groove 13, so the micro-pressure one-way valve 16 is in a closed state, preventing the secondary filtration sedimentation chamber 11 from supplying water to the water storage tank before it is full of water.

[0038] After the rain, when the water in the secondary filtration and sedimentation chamber 11 is gradually used up, the pressure on both sides of the micro-pressure one-way valve 16 is reversed, and the water pressure on one side of the retaining groove 13 is greater than the water pressure on one side of the secondary filtration and sedimentation chamber 11. Therefore, the micro-pressure one-way valve 16 is turned on, allowing the water in the retaining groove 13 to enter the secondary filtration and sedimentation chamber 11, thereby using the water in the retaining groove 13 to continue to supply water to the soil of the planting chamber 2.

Although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
