Description

Technical Field

[0001] The utility model belongs to the technical field of drainage structures, and in particular relates to a concealed drainage structure of a sponge city ecological waterscape. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city."

[0003] Cities can be like sponges, with good resilience in adapting to environmental changes and responding to natural disasters. The internationally common term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water will be released and utilized, allowing rainwater to migrate freely in the city.

[0004] However, the existing sponge city ecological waterscape drainage structure is not concealed enough, and is directly exposed, which reduces safety and makes the overall viewing experience poor. Utility Model Content

[0005] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a concealed drainage structure for sponge city ecological waterscape.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A concealed drainage structure of a sponge city ecological waterscape, comprising a drainage pipe body;

[0008] The upper edge of the drainage pipe body is provided with a folded edge for limiting position;

[0009] The bottom of the drainage pipe body is connected to the support rod through a strip plate, a drainage channel is formed between the strip plate and the inner wall of the drainage pipe body, and the upper end of the support rod protrudes upward from the pipe opening of the drainage pipe body;

[0010] The top of the support rod is connected to a flower pot, the bottom surface of the flower pot is higher than the folded edge, and an annular water inlet is formed between the bottom surface of the flower pot and the top surface of the folded edge.

[0011] It is further defined that a filter screen is installed at the water inlet. With such a structural design, the filter screen can filter out large-sized impurities at the water inlet to prevent them from entering the drainage pipe body and causing blockage.

[0012] It is further defined that the filter screen is provided with a fine-mesh screen, a plurality of support bars located on the upper edge of the fine-mesh screen, and a width edge connected to the plurality of support bars, and large filter holes are formed between the support bars. With such a structural design, the fine-mesh screen can filter and block debris, while the large filter holes on the top can improve the permeability and assist the water flow to drain quickly. The above structure takes into account both filtering performance and permeability.

[0013] It is further defined that a first rounded corner with a smooth transition is provided at the inner corner of the folded edge and the drainage pipe body, and a second rounded corner with a smooth transition is provided at the outer edge of the bottom of the flower pot. With such a structural design, the first rounded corner increases the expansion degree of the pipe mouth of the drainage pipe body, which is beneficial to the downward discharge of water, and the second rounded corner can increase the expansion angle of the water inlet, thereby facilitating the entry of water.

[0014] It is further defined that an observation tube is provided at the bottom of the inner surface of the flower pot, and the lumen of the observation tube penetrates the bottom of the flower pot. With such a structural design, during subsequent inspections, the staff can directly see through the observation tube whether blockage occurs inside the drainage pipe body without having to move the concealed drainage structure as a whole.

[0015] It is further defined that the bottom surface of the outer edge of the flower pot is provided with an annular bottom buckle with a hemispherical cross-section. Such a structural design makes it easy for the staff to grasp and apply force with their fingers when the concealed drainage structure needs to be moved or transferred.

[0016] The beneficial effects of the utility model are as follows: the drainage pipe body is directly inserted into the drain outlet from top to bottom, the outwardly expanded folded edge limits the insertion depth of the drainage pipe body, the flowerpot on the drainage pipe body is used to plant plants and fill with soil, thereby increasing the downward weight and ensuring the stability of the drainage pipe body in the drain outlet, and the top of the drainage pipe body is concealed by the flowerpot, which has stronger concealment and meets the application scenarios of ecological waterscape; when draining, water flows into the drainage pipe body from the annular water inlet between the bottom surface of the flowerpot and the top surface of the folded edge. Since the top is covered by the flowerpot, the water inlet cannot be directly found from the outside, so it has strong concealment and higher viewing interest. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-4 As shown, a concealed drainage structure of a sponge city ecological waterscape of the utility model includes a drainage pipe body 1;

[0032] The upper edge of the drainage pipe body 1 is provided with a folded edge 11 for limiting position;

[0033] The bottom of the drainage pipe body 1 is connected to the support rod 3 through the strip plate 2, and a drainage passage 6 is formed between the strip plate 2 and the inner wall of the drainage pipe body 1. The upper end of the support rod 3 protrudes upward from the pipe opening of the drainage pipe body 1;

[0034] The top of the support rod 3 is connected to the flower pot 4 , the bottom surface of the flower pot 4 is higher than the folded edge 11 , and an annular water inlet 7 is formed between the bottom surface of the flower pot 4 and the top surface of the folded edge 11 .

[0035] In this embodiment:

[0036] The drainage pipe body 1 is directly inserted into the drain outlet from top to bottom, and the outwardly expanded folded edge 11 limits the insertion depth of the drainage pipe body 1. The flowerpot 4 on the drainage pipe body 1 is planted with plants and filled with soil, thereby increasing the downward weight and ensuring the stability of the drainage pipe body 1 in the drain outlet. The top of the drainage pipe body 1 is concealed by the flowerpot 4, which is more concealed and meets the application scenario of ecological waterscape.

[0037] When draining, water flows into the drainage pipe body 1 from the annular water inlet 7 between the bottom surface of the flower pot 4 and the top surface of the folded edge 11. Since the water inlet 7 is covered by the flower pot 4 above, it cannot be directly found from the outside, so it is highly concealed and more interesting to watch.

[0038] Preferably, a filter screen 5 is installed at the water inlet 7. With this structural design, the filter screen 5 can filter out large-sized impurities at the water inlet 7 to prevent them from entering the drainage pipe body 1 and causing blockage. In fact, other filter structures can also be considered according to specific circumstances.

[0039] Preferably, the filter 5 is provided with a fine mesh 51, a plurality of support bars 52 located on the upper edge of the fine mesh 51, and a width edge 53 connected to the plurality of support bars 52, and a large filter hole 54 is formed between the support bars 52. With such a structural design, the fine mesh 51 can filter and block debris, while the large filter holes 54 above play a role in improving the permeability and assisting the rapid drainage of water. The above structure takes into account both the filtering performance and the permeability. In fact, other structural shapes of the filter 5 can also be considered according to specific circumstances.

[0040] Preferably, a first rounded corner with a smooth transition is provided at the inner corner of the folded edge 11 and the drainage pipe body 1, and a second rounded corner with a smooth transition is provided at the outer edge of the bottom of the flower pot 4. With such a structural design, the first rounded corner increases the expansion of the pipe opening of the drainage pipe body 1, which is beneficial for the downward flow of water, and the second rounded corner can increase the expansion angle of the water inlet 7, thereby facilitating the entry of water. In fact, other structural shapes that increase the expansion can also be considered according to specific circumstances.

[0041] Preferably, an observation tube 41 is provided at the bottom of the inner surface of the flower pot 4, and the lumen of the observation tube 41 penetrates the bottom of the flower pot 4. With this structural design, during the subsequent inspection, the staff can directly see whether the drainage pipe body 1 is blocked through the observation tube 41 without having to move the concealed drainage structure as a whole. In fact, other observation structures can also be considered according to specific circumstances.

[0042] Preferably, the outer bottom surface of the flower pot 4 is provided with a hemispherical annular bottom buckle 42, such a structural design makes it easy for the staff to grasp and apply force with their fingers when the concealed drainage structure needs to be moved. In fact, other gripping structures can also be considered according to specific circumstances.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
