Description

Technical Field

[0001] The utility model relates to the field of urban planning and ecological environment engineering, and specifically refers to a sunken green space in an ecological sponge park. Background Technique

[0002] A sponge city means that the city can be like a sponge and has good "elasticity" in aspects such as adapting to environmental changes and coping with natural disasters. Its main feature is that it can absorb water, store water, infiltrate water, and purify water during rainfall, and release and utilize the stored water when needed, so as to effectively cope with urban waterlogging and water resource shortage problems. In recent years, with the acceleration of the urbanization process, the concept of sponge city has been gradually applied to urban planning and construction. Especially in park renovation projects, this concept has been widely adopted to create a number of "sponge bodies" that can absorb water, store water, infiltrate water, and purify water, namely the so-called sponge parks. Due to the large floor area, diverse terrains, and rich landscape designs of park green spaces, they naturally have a strong infiltration ability and thus become the most effective "green sponges", playing an important role in regulating the urban water cycle.

[0003] However, although sponge parks can effectively absorb and infiltrate water on rainy days, during non-rainfall periods, the absorbed rainwater will gradually infiltrate into the ground or be lost through evaporation, and it is difficult to store it for a long time and reuse it. This phenomenon of water loss makes the park unable to fully play its "sponge" function during the dry season or when water is needed, thus affecting its sustainable water resource management ability. Therefore, how to better store water after rainwater absorption and improve the utilization efficiency of water resources has become a key technical problem in the construction of sponge parks.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the front and rear associated objects.

[0030] Such as Figure 1 And Figure 2As shown in the figure, the sunken green space of the ecological sponge park of the present utility model includes a grass layer 1, a soil layer 2, a gravel layer 3, a water storage cavity 4 arranged in sequence, and a switch structure 5 located on the water storage cavity 4. The water storage cavity 4 is buried inside the gravel layer 3, and its upper surface is a concave structure that gradually sinks towards the center, forming a recess 41. Part of the gravel in the gravel layer 3 accumulates in the recess 41, and the switch structure 5 is installed at the lowest point of the recess 41 to achieve automatic control of rainwater collection.

[0031] The grass layer 1 covers the ground surface, and below it are the soil layer 2 and the gravel layer 3 in sequence. The gravel layer 3, the soil layer 2, and the grass layer 1 are in a sunken structure along with the recess 41, and the water storage cavity 4 is buried in the gravel layer 3. The grass layer 1 is used to absorb and preliminarily filter rainwater, while the soil layer 2 further filters and purifies the infiltrated rainwater. The gravel layer 3 is located below the soil layer 2, and its main function is to further filter rainwater.

[0032] After the rainwater is filtered layer by layer through the grass layer 1, the soil layer 2, and the gravel layer 3, it finally converges on the upper surface of the recess 41. The design of the water storage cavity 4 enables the rainwater to gradually concentrate at the recess 41, so as to effectively collect and store the rainwater and prevent its loss.

[0033] The switch structure 5 is arranged at the lowest point of the recess 41 and is used to control the flow rate of rainwater entering the water storage cavity 4. Specifically, when the rainwater volume in the recess 41 reaches a certain height, the switch structure 5 automatically opens to allow the rainwater to flow into the water storage cavity 4 for storage.

[0034] First, after the rainwater penetrates through the grass layer 1, it is preliminarily filtered and adsorbed by the soil layer 2. This step can remove large particle impurities and some pollutants. Then, the rainwater continues to infiltrate into the gravel layer 3, where the gravel layer further filters the remaining impurities and quickly guides the rainwater to the recess 41 of the water storage cavity 4 through its high permeability. As the rainfall increases, the recess 41 on the upper surface of the water storage cavity 4 is gradually filled with rainwater, and the switch structure 5 automatically opens to introduce the rainwater into the water storage cavity 4 for storage. The rainwater enters the interior of the water storage cavity 4 through the switch structure 5. When the rainwater collection is completed, the switch structure 5 automatically closes, and the water storage cavity 4 stores the rainwater to facilitate coping with the urban water shortage problem. It effectively avoids the problem that rainwater in traditional sunken green spaces is easily lost through infiltration or evaporation. This design ensures the long-term storage of rainwater and is convenient for secondary utilization during dry or water-scarce periods, improving the utilization efficiency of water resources. Among them, the soil layer 2 is composed of soil rich in organic matter and with good particle structure, and the gravel layer 3 is composed of high-permeability materials such as coarse sand and crushed stones.

[0035] As Figures 2 to 7, the switch structure 5 includes a housing 51, a floating block 52, a mounting pipe body 53, a connecting rod 54, a driving member 55, a connecting shaft 56 and a plugging block 57; the housing 51 is connected to the recessed portion 41, the lower side of the housing 51 is open, the upper side of the housing 51 is provided with a top plate 511, and a partition plate 512 is arranged inside the housing 51. The partition plate 512 divides the interior of the housing 51 into an upper cavity 513 and a lower cavity 514. The number of the mounting pipe bodies 53 is at least two; the mounting pipe bodies 53 are inclined and arranged in the lower cavity 514, and the two mounting pipe bodies 53 are symmetrically arranged. Four strip-shaped protrusions 531 are arranged inside the mounting pipe body 53, the connecting rod 54 is arranged between the four strip-shaped protrusions 531, and a sliding space for the connecting rod 54 to slide is formed between the four strip-shaped protrusions 531. The driving member 55 is fixedly connected to the floating block 52 through a connecting pipe 58. The floating block 52 is arranged in the upper cavity 513, the driving member 55 is arranged in the lower cavity 514, and the connecting pipe 58 passes through the partition plate 512 and is slidably connected to the partition plate 512. Among them, a hole for the connecting pipe 58 to pass through is opened on the partition plate 512, and an annular sealing ring (not marked in the figure) is arranged in the hole. The sealing ring is used for sealing, so that the connecting pipe 58 and the partition plate 512 form a slidable sealed connection. A driving groove 551 is arranged on the driving member 55. The connecting shaft 56 is connected to the connecting rod 54, the connecting shaft 56 extends into the driving groove 551 and is slidably connected to the driving groove 551. The plugging block 57 is connected to one end of the connecting rod 54 away from the connecting shaft 56. The plugging block 57 is used for sealing the mounting pipe body 53, and a water inlet hole 515 is opened on the side wall of the upper cavity 513.

[0036] The driving member 55 includes a lifting plate 552, a connecting column 553 and a driving part 554; the lifting plate 552 is fixedly connected to the lower end of the connecting pipe 58, the connecting column 553 is fixedly connected to the lower surface of the lifting plate 552, the driving part 554 is connected to the lower end of the connecting column 553, the driving part 554 is inclined, and the driving groove 551 is arranged on the driving part 554.

[0037] Among them, the number of the installation tubes 53 is six, with three in each group, and the two groups of installation tubes 53 are symmetric to each other. The number of the connecting rods 54 is six, with three in each group. The connecting rods 54 are respectively arranged in the installation tubes 53. A blocking block 57 is connected to one end of each connecting rod 54 away from the driving member 55. The number of the connecting shafts 56 is two, and each connecting shaft 56 is respectively installed with a connecting rod 54. The number of the driving grooves 551 is four, with two in each group, and each group of driving grooves 551 is symmetric to each other. The two connecting shafts 56 respectively extend into the driving grooves 551. In the initial state, the driving member 55 is located at a low position, and the side of the blocking block 57 close to the inside of the housing 51 contacts the strip-shaped protrusion 531 to block the installation tube 53. When rainwater penetrates and the amount of rainwater reaches a certain level, the rainwater enters the upper cavity 513 through the water inlet hole 515. Subsequently, the floating block 52 moves upward under the buoyancy of the water. The floating block 52 drives the driving member 55 to move upward through the connecting pipe 58. Specifically, the connecting pipe 58 drives the lifting plate 552 to move upward, and the lifting plate 552 drives the driving part 554 to move upward through the connecting column 553. The driving groove 551 of the driving part 554 drives the connecting shaft 56 to move. Since the driving groove 551 is in an inclined state, when driving the two connecting shafts 56 to move upward, they also move away from each other. The connecting shaft 56 drives the connecting rod 54 to extend out of the installation tube 53, and the connecting rod 54 drives the blocking block 57 to extend out of the installation tube 53, and the blocking block 57 cancels the blocking of the installation tube 53. Subsequently, the rainwater located in the gravel layer 3 will enter the lower cavity 514 of the housing 51, and then enter the inside of the water storage cavity 4. When the rainwater gradually enters the water storage cavity 4, the water level in the gravel layer 3 drops, and then the floating block 52 also moves downward, and the driving member 55 moves downward accordingly. Finally, the driving groove 551 drives the connecting rod 54 to reset through the connecting shaft 56, and finally the blocking block 57 resets to continue blocking the installation tube 53, thereby realizing the closing of the water storage cavity 4 and storing the rainwater.

[0038] Through the change in the buoyancy of the floating block 52, when the rainwater accumulates to a certain liquid level height, the driving member 55 can automatically drive the connecting rod 54 and the blocking block 57 to cancel the blocking of the installation tube 53, realizing the timely collection of rainwater and avoiding water loss. At the same time, when the rainwater liquid level drops to a certain level, the floating block 52 drops with the water level and drives the driving member 55 and the connecting rod 54 to reset, and the blocking block 57 re-blocks the installation tube 53, thereby automatically closing the water storage cavity 4 and avoiding unnecessary water loss. The automatic opening and closing function ensures that rainwater only enters the water storage cavity 4 when the set water level is reached, and will not penetrate or evaporate and be lost through the gravel layer 3 during non-essential periods. This mechanism maximizes the utilization of rainwater resources. Especially in the dry season or when water is needed, the rainwater in the water storage cavity 4 can be retained for a long time and utilized when needed, thereby improving the efficiency of water resource management. Through the pure mechanical linkage of the floating block 52, the driving member 55, the connecting rod 54 and the blocking block 57, no external power supply or pneumatic equipment is required, and the reliability is high.

[0039] Specifically, the sunken green space of the ecological sponge park further includes a water intake pipe 6, and the water intake pipe 6 passes through the top plate 511, the floating block 52, the connecting pipe 58 and the driving member 55; the lower end of the water intake pipe 6 extends into the water storage cavity 4. The water intake pipe 6 extends into the interior of the water storage cavity 4 to facilitate connecting a pump 7 to pump out the water in the water storage cavity 4. At the same time, the floating block 52, the connecting pipe 58 and the driving member 55 are slidably connected to the water intake pipe 6, and the water intake pipe 6 plays a guiding role in the movement of the floating block 52, the connecting pipe 58 and the driving member 55 to ensure the stable operation of the floating block 52, the connecting pipe 58 and the driving member 55. Moreover, a sealing ring (not marked in the figure) is provided on the inner wall of the connecting pipe 58, so that the connecting pipe 58 and the water intake pipe 6 form a slidable sealed connection.

[0040] Specifically, one end of the water intake pipe 6 away from the water storage cavity 4 is connected to a pump 7, and the output end of the pump 7 is connected to a spraying mechanism 8. When the pump 7 is started, the water in the water storage cavity 4 is pumped out and then sprayed through the spraying mechanism 8, which is used to irrigate the turf layer 1 when there is no rain.

[0041] Specifically, the spraying mechanism 8 includes a first water delivery pipe 81, a second water delivery pipe 82 and a nozzle 83; the first water delivery pipe 81 is connected to the output end of the pump 7, the second water delivery pipe 82 is rotatably connected to the first water delivery pipe 81 through a connector 84, the nozzle 83 is connected to the second water delivery pipe 82, and the second water delivery pipe 82 is a bent pipe. The pump 7 pumps water into the first water delivery pipe 81. After passing through the first water delivery pipe 81, the water enters the second water delivery pipe 82. The water passes through the second water delivery pipe 82 and enters the nozzle 83 and is sprayed out by the nozzle 83. The second water delivery pipe 82 is rotatably connected to the first water delivery pipe 81 through the connector 84, which is convenient for adjusting the angle of the second water delivery pipe 82.

[0042] As Figure 8 shown, specifically, the sunken green space of the ecological sponge park further includes a driving mechanism 9, and the driving mechanism 9 is used to drive the second water delivery pipe 82 to rotate. The driving mechanism 9 includes a motor 91, a driving gear 92 and a driven gear 93. The output end of the motor 91 is connected to the driving gear 92, and the second water delivery pipe 82 passes through the driven gear 93 and is fixedly connected to the driven gear 93; the driving gear 92 and the driven gear 93 are meshed. When the motor 91 is started, the output end of the motor 91 drives the driving gear 92 to rotate. The driving gear 92 drives the driven gear 93 to rotate. The driven gear 93 drives the second water delivery pipe 82 to rotate. The second water delivery pipe 82 drives the nozzle 83 to rotate, and the rotation of the nozzle 83 will irrigate the surrounding turf in a circular range.

[0043] Specifically, the driving mechanism 9 further includes a protective housing 94, and the protective housing 94 is disposed outside the motor 91, the driving gear 92, and the driven gear 93. The protective housing 94 is used to protect the internal structure thereof.

[0044] The above specific embodiments do not constitute a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
