Description

Technical Field

[0001] The utility model relates to the technical field of sponge cities, in particular to a sponge ball for storing water in a sponge city and a water storage device thereof. Background Art

[0002] A sponge city refers to a city that can act like a sponge, storing rainwater on rainy days and using the stored rainwater for irrigation in dry climates.

[0003] At present, the rainwater storage devices of sponge cities generally include a storage pit dug into the ground, which is then filled with gravel so that the rainwater will be stored in the gaps between the gravel.

[0004] Since gravel is solid, it can only store about 150 liters of rainwater per cubic meter, which is a relatively small storage capacity. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a sponge ball for sponge city water storage and a water storage device thereof.

[0006] The utility model provides a sponge ball for sponge city water storage, comprising a spherical ball body;

[0007] The material of the sphere is plastic;

[0008] The sphere is provided with a plurality of through holes;

[0009] The through holes are parallel to each other and independent of each other;

[0010] The volume of the through hole accounts for more than 50% of the volume of the sphere.

[0011] The beneficial effects of the utility model are: 1. The arrangement of the through holes enables rainwater to be stored not only between the spheres but also in the through holes, thereby increasing the storage capacity of rainwater; 2. The structure of the through holes is used to increase the structural strength of the spheres; 3. Compared with gravel, the spheres are lighter and easier to transport; 4. The spheres are made of recycled plastic (polyolefin), which is recycled from waste streams, which is not only low-cost but also achieves plastic reuse, thereby achieving the effect of protecting the environment; 5. It can be reused and preserved permanently.

[0012] The specific structure of the through hole is as follows: the through hole includes a central hole coaxial with the sphere, and three layers of through holes are arranged outside the central hole, the through holes in the outermost layer are set as outer holes, the through holes in the middle layer are set as middle holes, and the through holes in the inner layer are set as inner holes; the outer holes, middle holes and inner holes are all arranged rotationally symmetrically. This not only achieves the effect of uniform strength distribution of the sphere, but also allows more through holes to be arranged, and more water output.

[0013] Furthermore, the outer hole, the middle hole and the inner hole are all in a fan-shaped shape; the volume of the through hole accounts for more than 90% of the volume of the sphere. This arrangement can increase the area of ​​the outer hole, the middle hole and the inner hole, and improve the volume of the sphere.

[0014] The outer hole is close to the outer wall of the sphere, and has low strength, which can easily lead to the breakage of the sphere. Based on this, a further improvement is that a raised reinforcement ring is provided at the center of the hole wall of the outer hole.

[0015] In order to further improve the structural strength of the sphere, specifically: a reinforcing rib is provided at one end of the central hole; and both ends of the reinforcing rib are connected to the inner wall of the central hole.

[0016] The utility model also provides a sponge city water storage device, including a water storage tank, in which a sponge ball for sponge city water storage is filled. Since the ball is spherical, has a straight shape, a stable structure, and can roll, the shape of the water storage tank is relatively low, and the water storage tank can be stably and automatically filled during filling, and a large hollow space is not likely to appear.

[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-5 As shown, the utility model discloses a sponge ball for urban sponge water storage, comprising a spherical ball 1, the material of which is recycled plastic.

[0028] The sphere 1 is integrally injection molded and is provided with a plurality of through holes, which are parallel to each other and independent of each other, so that the volume of the through holes accounts for more than 50% of the volume of the sphere 1. The specific structure of the through hole is as follows: the through hole includes a central hole 2 coaxial with the sphere 1, and three layers of through holes are arranged outside the central hole 2, the outermost layer of through holes is set as an outer hole 3, the middle layer of through holes is set as a middle hole 4, and the inner layer of through holes is set as an inner hole 5; the outer hole 3, the middle hole 4 and the inner hole 5 are all arranged rotationally symmetrically. In this way, not only can the effect of uniform strength distribution of the sphere 1 be achieved, but also more through holes can be arranged, and the water output is also greater.

[0029] The outer hole 3, the middle hole 4 and the inner hole 5 are all in a fan-shaped shape; the volume of the through hole accounts for more than 90% of the volume of the sphere 1. This arrangement can increase the end area of ​​the outer hole 3, the middle hole 4 and the inner hole 5, and improve the volume of the sphere 1.

[0030] A raised reinforcing ring 6 is provided at the center of the hole wall of the outer hole 3. A reinforcing rib 7 is provided at one end of the center hole 2; both ends of the reinforcing rib 7 are connected to the inner wall of the center hole 2. In this embodiment, the reinforcing rib 7 is in a "cross" shape. The above-mentioned settings are used to improve the structural strength of the sphere 1 and avoid cracking.

[0031] The beneficial effects of the utility model are: 1. The arrangement of the through holes enables rainwater to be stored not only between the spheres 1 but also in the through holes, thereby increasing the storage capacity of rainwater; 2. The structure of the through holes is used to increase the structural strength of the sphere 1; 3. Compared with gravel, the sphere 1 is lighter and easier to transport; 4. The sphere 1 is made of recycled plastic (polyolefin), which is recycled from the waste stream, which is not only low-cost but also realizes the reuse of plastic, thereby achieving the effect of protecting the environment; 5. It can be reused and permanently preserved.
