Now the flowers and plants in the park need to be watered frequently for maintenance, and there are many ways to water and irrigate flowers and plants. Generally, sprinkler irrigation is used for irrigation. In order to reduce labor intensity, pipes and nozzles can be pre-buried in the soil at the lower end of the area that needs irrigation, and water is introduced into the pipes and sprayed out from the nozzles to achieve the purpose of sprinkler irrigation of flowers and plants.

[0020] like Figures 1 to 12As shown, an irrigation device for landscaping engineering described in an embodiment of the present invention comprises a base 1, a side wall of the base 1 is fixedly connected with a pre-buried pipe 13, an end of the pre-buried pipe 13 is fixedly connected with a water tank 14, a first outer tube 11 is rotatably mounted at the top center of the base 1, a second outer tube 12 is movably mounted inside the first outer tube 11, a nozzle 121 is arranged on the outer wall of the upper end of the second outer tube 12, a power isolation device 2 is slidably mounted inside the first outer tube 11, the power isolation device 2 is used to drive the second outer tube 12 to rotate and drain the inside of the first outer tube 11; the power isolation device 2 comprises: a first limit plate 21 slidably mounted on the inner wall of the first outer tube 11, a transmission assembly 22 is slidably arranged inside the first limit plate 21, an isolation assembly 25 is arranged at the bottom end of the transmission assembly 22; a trigger assembly 23 is rotatably mounted on the top of the isolation assembly 25, the trigger assembly 23 is used to adjust the isolation assembly 25 and the The isolation component 25 is limited, a first circular plate 24 is fixedly installed on the top of the transmission component 22, a first fixed column 241 is fixedly installed on the outer wall of the first circular plate 24, and the end of the first fixed column 241 is fixedly installed on the bottom end of the second outer tube 12, the rotation of the isolation component 25 drives the transmission component 22 to slide inside the first limiting plate 21, the movement of the transmission component 22 drives the first circular plate 24 to rotate, and the rotation of the first circular plate 24 drives the second outer tube 12 to rotate; when the isolation component 25 is raised or lowered, the isolation component 25 can be converted into a piston mechanism for draining the interior of the first outer tube 11, a switching device 4 is provided inside the base 1, and the switching device 4 is used to connect the embedded pipeline 13 with the interior of the first outer tube 11, and connect the outside of the first outer tube 11, and a drainage device 3 is provided on the top of the second outer tube 12, and the drainage device 3 is used to discharge the water inside the second outer tube 12 after use.

[0021] It should be noted that this device can be used for watering flowers and plants on both sides of the road. The water tank 14, the embedded pipe 13 and the base 1 are embedded in the soil as a whole, and at the same time, the second outer tube 12 can be fully extended to water the flowers and plants. At this time, the water tank 14 is started, and the water tank 14 transports the water flow to the inside of the base 1 through the embedded pipe 13. The lower end of the base 1 is provided with a switching device 4. When the water tank 14 is not started, no water pressure is generated. At this time, the switching device 4 makes the first outer tube 11 connected to the outside world, and the second outer tube 12 is at the bottom of the first outer tube 11. , the pre-buried pipe 13 and the first outer pipe 11 are in a disconnected state. When water pressure is generated, the switching device 4 is lifted up, and the switching device 4 makes the pre-buried pipe 13 connected to the inside of the first outer pipe 11, and the first outer pipe 11 is disconnected from the outside. Therefore, water flows into the inside of the first outer pipe 11, and the water flow lifts the isolation component 25. At this time, the upper and lower ends of the isolation component 25 are in an isolated state, and the water flow drives the power isolation device 2 to rise as a whole. During the rising process of the power isolation device 2, the second outer pipe 12 is driven to rise. When the second outer pipe 12 rises to the top, as shown in FIG. Figures 3 to 8 As shown, the trigger assembly 23 contacts the inner wall of the top end of the first outer tube 11, so that the isolation assembly 25 is deformed, and a fan blade plate 253 is provided on the isolation assembly 25, so that the fan blade plate 253 is tilted, and the water flows into the interior of the second outer tube 12 through the tilted gap of the fan blade plate 253. While the water flows, the isolation assembly 25 is driven to rotate, and the rotation of the isolation assembly 25 drives the transmission assembly 22 to move, and the movement of the transmission assembly 22 drives the first circular plate 24 to rotate (the angle of rotation of the first circular plate 24 driven by the transmission assembly 22 is less than 180°), and the outer wall of the first circular plate 24 is connected to the first fixing column 241 The first fixing column 241 is connected to the second outer tube 12, thereby driving the second outer tube 12 to rotate, so as to achieve the effect of driving the second outer tube 12 to rotate at the same time during the sprinkling process. When the interior of the second outer tube 12 is full of water, water is sprayed from the nozzle 121 at the upper end of the second outer tube 12, and the rotation angle of the second outer tube 12 is less than 180°, so that the water flow will not be sprayed onto the road surface during the sprinkling process, thereby achieving the effect of sprinkling. After the sprinkling is completed, the water tank 14 is closed, and the second outer tube 12 is pressed to make the second outer tube 12 descend. Under the action of the trigger component 23, the fan blade 253 is reset (such as Figure 3 and Figure 4As shown, the isolation assembly 25 and the first outer tube 11 become piston-like devices), so that multiple fan blades 253 are in the same horizontal plane. At this time, the power isolation device 2 descends to drive the isolation assembly 25 to descend, and the fan blades 253 squeeze the water inside the first outer tube 11 downward. When the water tank 14 is closed, no water pressure is generated. Therefore, under the action of the switching device 4, the interior of the first outer tube 11 is not connected to the embedded pipeline 13, so that the interior of the first outer tube 11 is connected to the outside world. Then, under the action of the isolation assembly 25, the residual water in the first outer tube 11 can be discharged from the interior of the first outer tube 11, and a drainage device 3 is provided at the top of the second outer tube 12. The drainage device 3 discharges the residual water in the second outer tube 12 from the interior of the second outer tube 12 through a siphon action, so as to prevent the low temperature from causing residual water in the first outer tube 11 and the second outer tube 12, causing freezing and damage to the first outer tube 11 and the second outer tube 12, and the irrigation work is completed.

[0022] like Figures 4 to 7 As shown, a second slide groove 211 is provided inside the first limit plate 21, and the transmission assembly 22 includes: a first protrusion 223 slidably installed inside the first limit plate 21, a rectangular slider 221 is fixedly installed on the end of the first protrusion 223, an internal slide groove 222 is provided inside the rectangular slider 221, a first slider 225 and a second slider 227 are slidably installed inside the internal slide groove 222, a first rotating wall 224 is rotatably installed on the top of the first slider 225, the first rotating wall 224 is fixedly installed on the bottom end of the first circular plate 24, a second rotating wall 226 is rotatably installed on the bottom end of the second slider 227, a first cylinder 228 is fixedly installed on the bottom end of the second rotating wall 226, and the lower end of the first cylinder 228 is connected to the isolation assembly 25.

[0023] It should be noted that, considering the need to disclose the movement process of the transmission component 22, when the isolation component 25 drives the first cylinder 228 to rotate, the trigger component 23 makes the first cylinder 228 and the first circular plate 24 be at the same center of the circle, and the rotation of the first cylinder 228 drives the second rotating wall 226 to rotate around the center of the first cylinder 228. A second slider 227 is provided at the end of the second rotating wall 226. During the rotation of the second rotating wall 226, the second slider 227 is driven to move, and the second slider 227 slides inside the internal slide groove 222 on the rectangular slider 221. The movement of the second slider 227 can drive the rectangular slider 221 to slide inside the second slide groove 211 on the first limit plate 21, so that the rectangular slider 221 moves along the second slide groove 211 moves in the length direction, and the internal sliding groove 222 is provided with a first slider 225, the first slider 225 is connected to the first rotating wall 224, and the first circular plate 24 and the first cylinder 228 are always at the same center of a circle, so when the rectangular slider 221 moves along the length direction of the second sliding groove 211, it drives the first rotating wall 224 to rotate around the center of the first circular plate 24, and the length of the second rotating wall 226 is less than the length of the first rotating wall 224, so when the second rotating wall 226 rotates around the center of the first cylinder 228, the rotation angle of the first rotating wall 224 will not exceed 180°, so when driving the first circular plate 24 to rotate, it will not exceed 180°, and at the same time, it also prevents the problem of the first rotating wall 224 getting stuck during the rotation process.

[0024] like Figures 8 to 9 As shown, a cylindrical groove 229 is provided on the outer wall of the lower end of the first cylinder 228, and a first tooth 2291 is fixedly installed on the inner side wall of the cylindrical groove 229. The isolation component 25 includes: a third-party rectangular block 251 slidably installed on the outer wall of the lower end of the first cylinder 228, and a plurality of third cylinders 252 are rotatably installed inside the third-party rectangular block 251. A second tooth 254 is fixedly installed on the outer wall of the end of the third cylinder 252 close to the center of the first cylinder 228, and the second tooth 254 is meshed with the first tooth 2291. A fan blade plate 253 is fixedly installed on the end of the third cylinder 252 away from the center of the first cylinder 228. The fan blade plates 253 are arranged in a circular array on the outer wall of the third-party rectangular block 251, and the fan blade plate 253 is in the shape of a circular plate when it is in a horizontal plane.

[0025] It should be noted that, considering the need to disclose the problem of rotation adjustment of the isolation component 25, when the power isolation device 2 moves as a whole to the inner top of the first outer tube 11, the trigger component 23 is squeezed by the inner wall of the top of the first outer tube 11, and the squeezed trigger component 23 drives the third rectangular block 251 to move downward, and the third rectangular block 251 drives the third cylinder 252 and the blade plate 253 to move vertically downward along the length direction of the first cylinder 228. During the movement, the end of the third cylinder 252 is provided with a second tooth 254. , the second tooth 254 meshes with the first tooth 2291, and the blade plate 253 tilts, thereby adjusting the angle of the blade plate 253. When the water flows through the blade plate 253, it can drive the blade plate 253 to rotate, thereby achieving the purpose of rotating the first circular plate 24. When the trigger component 23 is reset, the third rectangular block 251 moves upward, thereby driving the second tooth 254 at the end of the third cylinder 252 to mesh with the first tooth 2291, thereby adjusting the angle of the blade plate 253, so that the blade plate 253 as a whole is restored to the state as shown in the figure. Figure 6 When the isolation assembly 25 moves downward as a whole, the plane surrounded by the four isolation assemblies 25 can squeeze out the water inside the first outer tube 11, thereby achieving the effect of emptying the first outer tube 11.

[0026] like Figures 8 to 9 As shown, the trigger assembly 23 includes: a lifting rod 231 rotatably mounted on the top of the third rectangular block 251, a lifting column 232 is fixedly mounted on the end of the lifting rod 231, a limiting circular groove 212 is provided on the first limiting plate 21, the lifting column 232 passes through the interior of the limiting circular groove 212, a second spring 233 is fixedly mounted on the top of the limiting circular groove 212, a top plate 234 is fixedly mounted on the top of the lifting column 232, and the end of the second spring 233 is fixedly connected to the bottom end of the top plate 234.

[0027] It should be noted that when the top of the top plate 234 contacts the inner wall of the top end of the first outer tube 11, the isolation assembly 25 will not rotate. Under the squeeze of water pressure, the first limit plate 21 and the transmission assembly 22 continue to move upward, thereby driving the first cylinder 228 to move upward continuously, and the isolation assembly 25 descends under the action of the trigger assembly 23, thereby achieving the purpose of adjusting the fan blade 253. The distance between the two top plates 234 is greater than the diameter of the first outer tube 11, which prevents the trigger assembly 23 from affecting the second outer tube 12 when it contacts the inner wall of the top end of the first outer tube 11.

[0028] like Figures 4 to 5As shown, the bottom side wall of the second outer tube 12 is provided with an edge protrusion 122, and the edge protrusion 122 is located inside the first outer tube 11. The top of the edge protrusion 122 is fixedly installed with a first spring 123, and the top of the first spring 123 is fixedly connected to the top inner wall of the first outer tube 11.

[0029] It should be noted that the edge protrusion 122 and the first spring 123 can ensure that when no water flows inside the first outer tube 11 and the second outer tube 12 , the second outer tube 12 is completely inside the first outer tube 11 due to the edge protrusion 122 and the first spring 123 .

[0030] like Fig.10 and Fig.12 As shown, a water trough 17 is provided inside the base 1, a switching device 4 is provided inside the base 1, the interior of the water trough 17 is connected to the switching device 4, and the switching device 4 includes: a T-block 44 slidably installed inside the water trough 17, a water flow trough 45 is provided inside the T-block 44, the upper end outer wall of the T-block 44 is connected to the pipe connecting port 15, a limiting connection block 41 is fixedly installed on the inner wall of the lower end of the first outer tube 11, a blocking cylinder 42 is fixedly installed on the bottom end of the limiting connection block 41, a third spring 43 is provided on the outer wall of the blocking cylinder 42, the center of the blocking cylinder 42 is concentric with the center of the water flow trough 45, and the diameter of the blocking cylinder 42 is the same as the diameter of the water flow trough 45.

[0031] It should be noted that the water flows into the interior of the pipe connection port 15 through the pre-buried pipe 13, contacts the outer wall of the T-block 44 through the pipe connection port 15, and lifts the T-block 44 under the action of water pressure, and then flows from the interior of the base 1 into the interior of the first outer tube 11, and a bottom stop block 111 is fixedly installed on the inner wall of the lower end of the first outer tube 11, and the bottom stop block 111 is used to block the power isolation device 2, prevent the bottom end of the power isolation device 2 from contacting the top of the limit connection block 41, thereby affecting the normal operation of the power isolation device 2 and the switching device 4. In use, a limiting connection block 41 is provided at the lower end of the first outer tube 11, and a blocking cylinder 42 is provided at the end of the limiting connection block 41, and the diameter of the blocking cylinder 42 is the same as the diameter of the water flow groove 45. Therefore, when the T-block 44 is subjected to an increase in water pressure, the interior of the first outer tube 11 is connected with the pre-buried pipe 13 to achieve the effect of water inlet and irrigation; when the T-block 44 is lowered by the action of the third spring 43, the water flow groove 45 is connected with the water trough 17, so that the first outer tube 11 is connected with the outside world, thereby achieving the effect of draining the interior of the first outer tube 11.

[0032] like Figures 10 to 12As shown, a siphon connection groove 16 is provided inside the base 1, and the siphon connection groove 16 is connected to the lower end of the water-passing groove 17, and the top of the siphon connection groove 16 is connected to the drainage device 3, and the drainage device 3 includes: a first fixed pipe 31 fixedly installed on the top of the base 1, the first fixed pipe 31 is located directly above the siphon connection groove 16, a second pipe 32 is slidably installed on the outer wall of the first fixed pipe 31, and a top connecting block 33 is fixedly installed on the top of the second pipe 32, a pipe connecting groove 331 is provided inside the top connecting block 33, and a third pipe 34 is fixedly installed on the end of the top connecting block 33, the pipe connecting groove 331 is used to connect the second pipe 32 and the third pipe 34, and a bottom water discharge block 35 is provided at the bottom end of the third pipe 34, and the top of the bottom water discharge block 35 is fixedly connected to the top of the first circular plate 24.

[0033] It should be noted that the height of the siphon connection groove 16 is always lower than the second outer tube 12, and the siphon connection groove 16 and the first fixed pipe 31 as well as the second pipe 32 and the third pipe 34 are kept in a connected state. When the first outer tube 11 rises and starts to take in water, the second outer tube 12 also rises, but there is no water inside the second outer tube 12, then the bottom water discharge block 35 and the third pipe 34 are in a sealed state, and at this time there is no water inside the third pipe 34. When the inside of the second outer tube 12 is filled with water, the second outer tube 12 drives the second pipe 32 and the first fixed pipe 31 to descend, and the lower end of the first fixed pipe 31 is provided with a bottom protrusion 35. 11, when the second pipe 32 falls to the bottom, the bottom water discharge block 35 continues to fall, so that the second outer pipe 12 is connected with the inside of the third pipe 34. At this time, under the action of the water pressure inside the second outer pipe 12, the water flow will quickly enter the inside of the third pipe 34 from the water discharge port 351, forming a siphon effect. The upper end of the second outer pipe 12 is provided with a nozzle 121. When the water inside the second outer pipe 12 drops, the inside of the second outer pipe 12 will not generate negative pressure. Then, the water inside the second outer pipe 12 will all flow out under the siphon effect until there is no water flow inside the third pipe 34, thereby achieving the effect of emptying the water flow inside the second outer pipe 12.

[0034] like Fig.11 As shown, a limiting protrusion 341 is fixedly installed on the inner wall of the bottom end of the third pipe 34, and a bottom water discharge block 35 is slidably installed on the inner wall of the limiting protrusion 341. The top of the bottom water discharge block 35 is provided with a protrusion to limit the third pipe 34, and the outer wall of the bottom water discharge block 35 is provided with a water discharge port 351.

[0035] It should be noted that the drain port 351 on the bottom drain block 35 cooperates with the third pipe 34 so that when the second outer tube 12 is completely filled with water, there is no water inside the third pipe 34. When the second outer tube 12 drops to the bottom, the third pipe 34 and the bottom drain block 35 cooperate to form a siphon effect, thereby sucking out the water inside the second outer tube 12.

[0036] like Fig.12 As shown, the outer wall of the first fixed pipe 31 is provided with a bottom protrusion 311 , and when the second outer tube 12 is at the bottom end inside the first outer tube 11 , the bottom protrusion 311 enables the drain port 351 to communicate with the inner wall of the second outer tube 12 .

[0037] It should be noted that the outer wall of the first fixed pipe 31 is provided with a bottom protrusion 311 , and when the second outer tube 12 is at the bottom end inside the first outer tube 11 , the bottom protrusion 311 enables the drain port 351 to communicate with the inner wall of the second outer tube 12 .

[0038] like Figures 4 to 5 As shown, the diameter of the edge protrusion 122 is smaller than the length of the lifting rod 231 , so as to protect the top plate 234 from touching the edge protrusion 122 during use.

[0039] It should be noted that the diameter of the edge protrusion 122 is smaller than the length of the lifting rod 231 , so as to protect the top plate 234 from touching the edge protrusion 122 during use.

[0040] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
