Description

Technical Field

[0001] The utility model relates to a water-saving irrigation system, in particular to a water-saving irrigation system based on a sponge city, belonging to the technical field of sponge cities. Background Technique

[0002] A sponge city is a new generation of urban rainwater management concept, which means that the city has good elasticity in adapting to environmental changes and coping with natural disasters brought by rainwater. The existing methods for realizing an ecological sponge city are relatively single, and usually there are water storage devices, water purification devices and drainage devices underground.

[0003] Urban greening plants need to be irrigated according to their growth needs. In practice, the main method is to use a sprinkler truck for spraying. This method can only moisten the soil surface layer, and most of the water is evaporated or flows away, which is not conducive to water resource conservation. And when the pipeline is buried in the soil, the holes of the pipeline are easily blocked. For this reason, we provide a water-saving irrigation system based on a sponge city.

[0007] Specifically, a guide block is fixed on the side of the rotating shell away from the fixed shell, and a guide plate slidably connected with the guide block is fixed on the side surface of the water outlet pipe. The rotating shell can be limited and guided through the guide plate and the guide block.

[0008] Specifically, a water guiding column is fixed to the inner wall of the rotating shell. The water guiding column is arranged at the first water outlet hole. The arrangement of the water guiding column can guide the water discharged from the water outlet pipe.

[0009] Furthermore, a sealing gasket is fixed to the second water outlet hole. The outer contour of the sealing gasket is annular. The arrangement of the sealing gasket can improve the sealing effect.

[0010] Specifically, a guiding rod is fixed to the inner wall of the mounting shell. The guiding rod penetrates through the sliding block and is slidably connected to the sliding block. The arrangement of the guiding rod can guide and limit the sliding block.

The outer contour of the sealing gasket 8 is annular. Setting the sealing gasket 8 can improve the sealing effect and avoid the situation of poor sealing.

[0026] Please pay special attention to Figure 3 and Figure 4, a drainage mechanism 2 is provided on the water outlet pipe 5. The drainage mechanism 2 includes a fixed shell 201 fixed to the side of the water outlet pipe 5. A motor 202 is fixed to the inner wall of the fixed shell 201. The output end of the motor 202 is fixed with a gear 203. The start of the motor 202 can drive the gear 203 to rotate. A rotating shell 205 is rotatably connected to the side of the water outlet pipe 5. A first water outlet hole 2051 penetrating the rotating shell 205 is provided on the side of the rotating shell 205. A guide block 2053 is fixed to the side of the rotating shell 205 away from the fixed shell 201. A guide plate 2052 slidably connected to the guide block 2053 is fixed to the side of the water outlet pipe 5. The rotating shell 205 can be limited and guided through the guide plate 2052 and the guide block 2053. A water guide column 211 is fixed to the inner wall of the rotating shell 205. The water guide column 211 is arranged at the first water outlet hole 2051. The inner diameter of the first water outlet hole 2051 is equal to the inner diameter of the water guide column 211, so that the water flow can be discharged more smoothly from the first water outlet hole 2051 and the water guide column 211. The water guide column 211 can guide the water discharged from the water outlet pipe 5. A tooth ring 204 meshing with the gear 203 is fixed to the side of the rotating shell 205 close to the fixed shell 201. The rotation of the gear 203 will drive the tooth ring 204 to rotate. The tooth ring 204 will drive the rotating shell 205 to rotate on the side of the water outlet pipe 5. While the rotating shell 205 rotates, it will also drive the guide plate 2052 to rotate on the guide block 2053.

[0027] Please refer particularly to Figure 5 and Figure 6 , an installation shell 206 is fixed to the inner wall of the rotating shell 205. A compression spring 207 is fixed in the installation shell 206. The other end of the compression spring 207 is fixed with a slider 208. When the through hole 210 contacts the side of the water outlet pipe 5, the compression spring 207 is in a compressed state. A guide rod 2081 is fixed to the inner wall of the installation shell 206. The guide rod 2081 penetrates the slider 208 and is slidably connected to the slider 208. The slider 208 will slide on the guide rod 2081 while moving. The guide rod 2081 can guide and limit the slider 208. A sealing ball 209 is fixed to the other side of the slider 208. The outer diameter of the sealing ball 209 is larger than the inner diameter of the second water outlet hole 6. Thus, the second water outlet hole 6 can be blocked by the sealing ball 209. A through hole 210 is provided on one side of the connection between the rotating shell 205 and the water outlet pipe 5. The diameter of the through hole 210 is larger than the diameter of the sealing ball 209. The sealing ball 209 can slide in the through hole 210.

[0028] Working principle: by burying the water outlet pipe 5 in the soil, starting the water pump 3 to pump the water stored in the water tank 1 into the water outlet pipe 5 through the connecting pipe 4, and then the water flows through the second water outlet hole 6, the first water outlet hole 2051, and the water guide column 211 to discharge the water to supply water to the soil, moisten the inner layer of the soil, and effectively prevent the water from evaporating or flowing away. When it is not necessary to supply water to the soil, start the motor 202, and the motor 202 will drive the gear ring 204 to rotate through the gear 203. The cooperation can drive the rotating shell 205 to rotate on the side of the water outlet pipe 5, and then the rotating shell 205 drives the installation shell 206 to move the sealing ball 209 to the second water outlet hole 6. Under the elastic force generated by the deformation of the compression spring 207, the sealing ball 209 is pressed against by the slider 208, and the sealing ball 209 is fixed at the second water outlet hole 6. The second water outlet hole 6 is blocked by the sealing ball 209 to prevent the second water outlet hole 6 on the water outlet pipe 5 from being blocked, so that the water outlet pipe 5 buried in the soil can drain water stably to achieve the purpose of saving water.
