Description

Technical Field

[0001] The utility model relates to a water-saving and energy-saving green space irrigation system for sponge cities, specifically a water-saving and energy-saving green space irrigation system for sponge cities, belonging to the technical field of green space irrigation. Background Technique

[0002] A sponge city is an urban rainwater management strategy based on the concepts of natural accumulation, natural infiltration, and natural purification. By simulating the water absorption, water storage, water infiltration, and water purification functions of nature, it aims to solve the dual problems of urban waterlogging and water resource shortage, and then improve the urban ecological environment. Sponge cities will set up green spaces to temporarily store rainwater, use plants to adsorb and degrade pollutants to improve water quality, and then release or infiltrate it into the ground. And irrigation systems will be set up on the green spaces to irrigate the green spaces.

[0003] A water-saving and energy-saving green space irrigation system for sponge cities disclosed in Chinese Patent Publication No. CN220383855U can be assembled at the green space and semi-buried in the green space. When irrigating the green space, it can be connected to the water outlet pipe of the sprinkler truck for water supply. After the water enters the pipeline of the green space irrigation system, it can be guided and sprayed out, and is blocked by the corresponding baffle to flow outside for irrigating the green space, so that the sprinkler truck does not need to drive along the road to irrigate the green space, realizing water saving and energy saving when the sprinkler truck irrigates the green space and meeting the green space irrigation requirements of sponge cities.

[0004] However, in the process of implementing the technical solution of the above patent, the irrigation holes may be blocked by sundries such as soil or plants in the green space when not in use. In the green space irrigation of sponge cities, in order to avoid the energy consumption caused by using a sprinkler truck and the waste of water resources when the sprinkler truck sprinkles water outside the green space, people will realize water-saving and energy-saving irrigation through pre-buried pipelines. However, the irrigation holes of the existing pipelines are directly exposed, and the exposed irrigation holes are easily blocked by sundries such as soil, plants, and garbage, resulting in some irrigation holes being unable to discharge water and affecting the irrigation effect of the green space. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water-saving and energy-saving green space irrigation system for sponge cities to solve the problem that the irrigation holes on the pipeline in the prior art are in an exposed state and are easily blocked by sundries such as soil or plants in the green space when not in use.

[0010] Preferably, one end of the irrigation pipe is fixedly connected with an external thread pipe, and the other end of the irrigation pipe is fixedly connected with a connecting pipe. An internal thread pipe is sleeved on the outer surface of the connecting pipe. Both the L-shaped pipe and the external thread pipe are adapted to the internal thread pipe. Screwing the internal thread pipe onto the external thread pipe can realize the connection of multiple irrigation pipes, and screwing the internal thread pipe onto the L-shaped pipe can realize the connection of the irrigation pipe and the L-shaped pipe.

[0011] Preferably, a burying seat is fixedly connected to the outer surface of the irrigation pipe. The burying seat can be buried under the soil of the sponge city green space, thereby ensuring the stability of the irrigation pipe.

[0012] Furthermore, a plugging head is arranged outside the L-shaped pipe. The external thread pipe is adapted to the plugging head.

[0028] An embodiment of the present utility model provides a water-saving and energy-saving green space irrigation system for sponge cities.

[0029] Please refer with emphasis to Figure 1 and Figure 2, including an L-shaped pipe 1, the top end of the L-shaped pipe 1 is fixedly connected with an extension hose 2, and a water receiving head is arranged on the extension hose 2. Through the water receiving head, the extension hose 2 can be connected to an external sprinkler or other water supply equipment.

[0030] Please refer particularly to Figure 1 、 Figure 3 and Figure 4 , a plurality of irrigation components 3 are arranged outside the L-shaped pipe 1. The irrigation component 3 includes an irrigation pipe 31 and a foam floating board 32. The number of irrigation pipes 31 is set according to the size of the green space in the sponge city. Six irrigation holes 33 are formed on the outer surface of the irrigation pipe 31. Two symmetrically arranged arc-shaped baffles 34 are hinged on the outer surface of the irrigation pipe 31. The arc-shaped baffles 34 are adapted to the irrigation holes 33. By injecting water into the extension hose 2, the water will sprinkle out from the irrigation holes 33 after passing through the extension hose 2, the L-shaped pipe 1 and the irrigation pipe 31, so as to irrigate the green space in the sponge city. Compared with the irrigation by a sprinkler, it can avoid water from spilling outside the green space and also reduce the energy consumption of the sprinkler, having the advantages of water saving and energy saving.

[0031] Three connecting rods 35 are hinged on one side surface of each of the two arc-shaped baffles 34 close to the irrigation pipe 31. The connecting rods 35 are adapted to the irrigation holes 33. One ends of the plurality of connecting rods 35 far from the arc-shaped baffles 34 are all hinged on the outer surface of the foam floating board 32. When water is injected into the irrigation pipe 31, the foam floating board 32 will rise due to buoyancy and push the arc-shaped baffles 34 to unfold through the connecting rods 35. When there is no water in the irrigation pipe 31, the foam floating board 32 and the arc-shaped baffles 34 will fall due to their own gravity, closing the arc-shaped baffles 34.

[0032] Two symmetrically arranged sliding pipes 36 are fixedly connected to the outer surface of the foam floating board 32. Two guide rods 37 are fixedly connected to the inner wall of the irrigation pipe 31. The two sliding pipes 36 are respectively slidably connected to the outer surfaces of the two guide rods 37. The sliding pipes 36 and the guide rods 37 play a guiding role for the movement of the foam floating board 32.

[0033] One end of the irrigation pipe 31 is fixedly connected with an external thread pipe 310, and the other end of the irrigation pipe 31 is fixedly connected with a connecting pipe 38. An internal thread pipe 39 is sleeved on the outer surface of the connecting pipe 38. Both the L-shaped pipe 1 and the external thread pipe 310 are adapted to the internal thread pipe 39. Screwing the internal thread pipe 39 onto the external thread pipe 310 can realize the connection of multiple irrigation pipes 31, and screwing the internal thread pipe 39 onto the L-shaped pipe 1 can realize the connection of the irrigation pipe 31 and the L-shaped pipe 1.

[0034] A burying seat 311 is fixedly connected to the outer surface of the irrigation pipe 31. The burying seat 311 can be buried under the soil of the green space in the sponge city, thus ensuring the stability of the irrigation pipe 31.

[0035] Please refer particularly to Figure 1 andFigure 2 An end plug 5 is provided outside the L-shaped pipe 1. The external threaded pipe 310 is adapted to the end plug 5, and the end plug 5 can be screwed onto the external threaded pipe 310 of the irrigation pipe 31 that is farthest from the L-shaped pipe 1, so as to realize the plugging of the irrigation pipe 31.

[0036] Please refer particularly to Figure 1 and Figure 5 A protection assembly 4 is provided outside the L-shaped pipe 1. The protection assembly 4 includes a protection box 41. The L-shaped pipe 1 passes through the protection box 41 and is fixedly connected to the protection box 41. A sealing plate 42 is hinged on the upper surface of the protection box 41. When the sealing plate 42 is closed, it can protect the extension hose 2 in the protection box 41.

[0037] A fixed frame 43 is fixedly connected to the upper surface of the protection box 41 described above. A sliding block 44 is slidably connected to the inner wall of the fixed frame 43. An inclined surface is provided on the sliding block 44. When the sealing plate 42 is closed, the sealing plate 42 will push the sliding block 44 to move towards the inside of the fixed frame 43 through the inclined surface of the sliding block 44.

[0038] Three springs 45 are fixedly connected to the outer surface of the sliding block 44. One end of the three springs 45 far from the sliding block 44 is fixedly connected to the inner wall of the fixed frame 43. When the sealing plate 42 is closed, the sliding block 44 can block the sealing plate 42 to prevent the sealing plate 42 from being blown open by the wind.

[0039] Working principle: According to the size of the green space in the sponge city, multiple irrigation pipes 31 are connected. When connecting, the internal threaded pipe 39 of the first irrigation pipe 31 is screwed onto the L-shaped pipe 1, so that the connecting pipe 38, the irrigation pipe 31 and the L-shaped pipe 1 are connected. Then, the internal threaded pipe 39 of the next irrigation pipe 31 is sequentially screwed onto the external threaded pipe 310 of the previous irrigation pipe 31 to connect multiple irrigation pipes 31. Then, the plug 5 is tightened onto the external threaded pipe 310 of the last irrigation pipe 31, and the bottom of the protection box 41 and the buried seat 311 are buried in the soil of the green space. When irrigation is required, the extension hose 2 is taken out and connected to an external sprinkler or other water supply equipment. By injecting water into the extension hose 2, after the water is sequentially injected into the extension hose 2, the L-shaped pipe 1 and the irrigation pipe 31, the foam floating plate 32 will rise due to buoyancy, and the arc-shaped baffle 34 will be pushed by the connecting rod 35 to unfold to expose the irrigation holes 33, and the water will be sprinkled out from the irrigation holes 33 to irrigate the green space. When the water injection stops, under the action of its own gravity, the foam floating plate 32 and the arc-shaped baffle 34 will fall, and the arc-shaped baffle 34 will block the irrigation holes 33. At the same time, after the extension hose 2 is placed in the protection box 41, the sealing plate 42 is closed. The sealing plate 42 will push the sliding block 44 to move into the fixed frame 43 through the inclined surface of the sliding block 44 and compress the spring 45. When the sealing plate 42 is closed, under the elastic force of the spring 45, the sliding block 44 is pushed to reset and block the sealing plate 42. This system can close the arc-shaped baffle 34 and block the irrigation holes 33 when irrigation is not required, avoiding the exposure of the irrigation holes 33 and being blocked by dirt and other sundries.
