Description

[0002] Urban management refers to a systematic project that uses a variety of means and mechanisms to plan, organize, direct, coordinate and serve various urban activities. It aims to build an orderly, harmonious and livable urban environment to support the sustainable development of the city and the high-quality life of residents. Modern urban management is multi-dimensional, multi-structural and multi-level. Its complexity and professional division of labor require managers to have comprehensive coordination capabilities. The core of urban management is the management of urban infrastructure, public service facilities and social public affairs. As an important part of urban infrastructure, the effective management of greening is crucial to improving the urban ecological environment and the quality of life of residents.

[0003] Urban greening requires irrigation devices, not only to ensure the normal growth of plants, improve irrigation efficiency, and save water resources, but also to protect the urban ecological environment, enhance the urban landscape, and promote technological and management progress.

[0004] Existing irrigation devices usually use manual irrigation or fixed sprinkler nozzles for irrigation, which results in the inability to adjust the spraying range according to the width and height of the roadside greening when irrigating the roadside greening, resulting in water being sprayed outside the greening, resulting in a waste of water resources. While spraying, the water will also splash onto people passing by on the non-motorized vehicle lane, which has certain limitations. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1 Reference Figures 1 to 11 , which is the first embodiment of the present invention, provides a method for using a greening irrigation device based on urban management. Through the method for using a greening irrigation device based on urban management, the height and width of the spray irrigation can be adjusted according to the height and width of the green vegetation, while reducing the range of water splashing onto the non-motorized vehicle lane.

[0038] The height of the water tank 102 is adjusted according to the height of the green vegetation through the hydraulic rod 201 inside the height adjustment mechanism 200, so that the water tank 102 drives the water injection pipe 105 to adjust the spraying height of the nozzle; The inclination of the water injection pipe 105 is adjusted according to the width of the green vegetation through the width adjustment component 308 inside the width adjustment mechanism 300, so that the water injection pipe 105 can adapt to the width of the green vegetation for spraying after being tilted; When the water injection pipe 105 sprays through the spray head 106, the blowing assembly 303 is driven to operate, so that the blowing assembly 303 blows air downward, thereby reducing the range of the spray head 106 spraying toward the non-motorized vehicle lane.

[0039] The height adjustment mechanism 200 can adjust the height of the water injection pipe 105 to adapt to green vegetation of different heights for spraying irrigation, and can also adjust the content of liquid fertilizer according to green vegetation of different heights.

[0040] The width adjustment mechanism 300 can adjust the inclination of the water injection pipe 105 through the width adjustment component 308, so that the water injection pipe 105 can adapt to green vegetation of different widths for spraying irrigation after adjustment, and the detection component 310 can be used to avoid collision between the water injection pipe 105 and trees on the green vegetation.

[0041] The blowing assembly 303 can be started while the water injection pipe 105 is spraying and irrigating the green vegetation, so that the blowing assembly 303 can reduce the spraying range of the spray head 106 on the non-motorized vehicle lane.

[0042] Example 2 Reference Figures 1 to 3 , which is the second embodiment of the present invention, provides a greening irrigation device based on urban management. Through the height adjustment mechanism 200, the height of the spraying irrigation is adjusted according to the height of the greening vegetation, and the content of the liquid fertilizer is adjusted according to the height of different greening vegetation.

[0043] The height adjustment mechanism 200 includes a hydraulic rod 201, which is fixedly connected to the four corners of the top of the mobile frame 101, the top of the hydraulic rod 201 is fixedly connected to the bottom of the water tank 102, the top of the mobile frame 101 is fixedly connected to a sliding rod 202, the top of the sliding rod 202 penetrates to the top of the water tank 102, the top of the sliding rod 202 is fixedly connected to the bottom of the fertilizer tank 103, an installation groove 203 is opened on the left side of the top of the water tank 102, a water supply pipe 204 is fixedly installed inside the installation groove 203, the water supply pipe 204 is fixedly connected to the output end of the water pump 104, and the left and right sides of the top of the water supply pipe 204 are fixedly connected to a fertilizer adjustment component 205.

[0044] The fertilizer adjustment component 205 includes a one-way solenoid valve 205a, the top of which is fixedly connected to a mounting ring 205b, the top of which is fixedly connected to a fixed telescopic hose 205c, an adjustment discharge port 205d is provided on the left side of the bottom of the inner wall of the fertilizer box 103, two adjustment discharge ports 205d are provided, an adjustment block 205e is movably connected inside the adjustment discharge port 205d, a connecting frame 205f is fixedly connected inside the mounting ring 205b, and the top of the connecting frame 205f is fixedly connected to the bottom of the adjustment block 205e.

[0045] Specifically, after the hydraulic rod 201 on the mobile frame 101 is started, it can adjust the height of the water tank 102, so that the water tank 102 can move up and down on the surface of the sliding rod 202, so that the sliding rod 202 can support the fertilizer box 103 and ensure the stability of the water tank 102 when it moves up and down. At the same time, as the water tank 102 moves, the adjustment block 205e at the top of the adjustment discharge port 205d will be driven to move, so that the adjustment block 205e will adjust the displacement of the adjustment discharge port 205d when it moves up and down inside the adjustment discharge port 205d, so that the water injection pipe 105 can adjust the amount of liquid fertilizer flowing through the adjustment discharge port 205d when facing green vegetation of different heights.

[0046] Furthermore, when the height of the water injection pipe 105 needs to be adjusted, the hydraulic rod 201 on the mobile frame 101 is started, so that after the hydraulic rod 201 is started, it will drive the water tank 102 to move up and down on the surface of the sliding rod 202, so that the water tank 102 can drive the fixed pipe 302 to move up and down through the fixed frame 301, so that the fixed frame 301 can drive the mounting frame 305 to move through the movable frame 306 and the internal fixing pin 307, so that the mounting frame 305 can drive the water injection pipe 105 to adjust its height.

[0047] During the height adjustment of the water tank 102, the water supply pipe 204 inside the installation groove 203 will be driven to move up and down, so that the water supply pipe 204 will drive the one-way solenoid valve 205a to move during the up and down movement, so that the one-way solenoid valve 205a can drive the installation ring 205b to move after the movement, so that the installation ring 205b can drive the adjustment block 205e to move inside the adjustment discharge port 205d through the internal connecting frame 205f after the movement, so that the adjustment block 205e can adjust the size of the adjustment discharge port 205d, and at the same time, the fixed telescopic hose 205c can ensure that the adjustment discharge port 205d is always connected with the installation ring 205b.

[0059] In addition, the infrared sensor 310b on the mounting plate 310a will detect in real time whether there are obstacles or trees in front of the water injection pipe 105, so that the infrared sensor 310b can transmit the signal to the programmable data signal controller 310c as soon as the tree or obstacle is detected, so that the programmable data signal controller 310c can start the motor 308a as soon as possible, so that the motor 308a can drive the water injection pipe 105 to rotate and fold as soon as possible after it is started again, so that the rotating and folded water injection pipe 105 can avoid collision with obstacles or trees.

[0060] Furthermore, the reset tension spring 309b inside the reset cylinder 309a can drive the fixed disk 309c to reset through its own tension, so that the water injection pipe 105 can be reset to the first rotation adjustment angle after being folded twice.

[0061] After the water injection pipe 105 rotates 90 degrees, the plastic pipe 311c will contact the adjustment plate 311b on the positioning frame 311a, so that the plastic pipe 311c in contact with the adjustment plate 311b can change the spraying direction of the sprinkler head 106, so that the water injection pipe 105 can still spray the green vegetation after driving the sprinkler head 106 to rotate 90 degrees.

During the rotation of the mounting frame 305, the reset pull rope 309d is pulled. As the reset pull rope 309d is pulled, the fixed plate 309c is driven to move inside the reset cylinder 309a, so that the fixed plate 309c can drive the reset tension spring 309b to stretch, so that when the winding rope 308e releases the traction on the mounting frame 305, the reset tension spring 309b inside the reset cylinder 309a can drive the fixed plate 309c to reset through its own tension, so that the fixed plate 309c can drive the mounting frame 305 to reset through the reset pull rope 309d. After the height and width adjustment are completed, the water pump 104 is started to allow the water pump 104 to pump the stored water. The irrigation water in the water tank 102 is injected into the water supply pipe 204, so that the water in the water supply pipe 204 is injected into the fixed pipe 302 through the connecting pipe 303b, and the water in the fixed pipe 302 enters the water injection pipe 105 through the connecting telescopic hose 403, so that the water in the water injection pipe 105 can be injected into the sprinkler head 106 through the plastic pipe 311c for spraying. At the same time, the water flow will carry the liquid fertilizer out when passing through the water supply pipe 204, and the water flow in the water supply pipe 204 will be injected into the fixed pipe 302 through the connecting pipe 303b, so that the transmission blade 303d will rotate, so that the transmission blade 303d can drive the sealing rotating ring 303a to rotate through the transmission frame 303c after the rotation of the transmission blade 303d, so that the sealing rotating ring 303a can rotate. After the rotation of 03a, the tooth 303e can be driven to rotate, and the tooth 303e can be driven to rotate by the transmission gear 303g, and the transmission gear 303g can be driven to rotate by the first transmission rod 303f, and the first transmission rod 303f can be driven to rotate by the universal transmission shaft 303h, and the universal transmission shaft 303h can drive the transmission sleeve 303j to rotate through the sliding transmission rod 303i, and the transmission sleeve 303j can be driven to rotate by the second transmission rod 303k, and the second transmission rod 303k can be driven to rotate by the transmission bevel gear 303q inside the bellows 303l, and the transmission bevel gear 303q can be driven to rotate by the bevel gear rod 303m inside the bellows 303l.The rotation of the bevel gear rod 303m can drive the driven bevel gear 303o inside the movable plate 303n to rotate, and the rotation of the driven bevel gear 303o can drive the fan 303p to rotate, so that the fan 303p can blow air downward after rotating, so that the airflow blown out from the bellows 303l can change the splashing trajectory of the irrigation water splashing outside, thereby reducing the splashing range of the irrigation water to the non-motorized vehicle lane. When the water injection pipe 105 encounters a tree during the mobile spraying of the vegetation greening, the red on the mounting plate 310a The external sensor 310b will detect it immediately, and transmit the signal to the programmable data signal controller 310c, so that the programmable data signal controller 310c can restart the motor 308a, so that the motor 308a can drive the worm 308b to rotate after restarting, so that the worm 308b can drive the worm wheel 308c supported by the support shaft 308f-1 and the support frame 308f-2 to rotate after the rotation of the worm wheel 308c. The winding drum 308d supported by the support frame 308f-2 rotates, so that the winding drum 308d can drive the winding rope 308e to be wound after the rotation, and the winding rope 308e can drive the mounting frame 305 to rotate again, so that the mounting frame 305 can drive the water injection pipe 105 to be folded 90 degrees, so that the folded water injection pipe 105 can avoid the trees on the green vegetation, and at the same time, the folded water injection pipe 105 can drive the sprinkler head 106 to move through the plastic pipe 311c, so that the plastic The material tube 311c will contact the adjustment plate 311b on the positioning frame 311a, so that the adjustment plate 311b can change the direction of the sprinkler head 106 at the bottom of the plastic tube 311c, so that the sprinkler head 106 faces the green vegetation, so that the water injection pipe 105 can still irrigate the green vegetation after being folded 90 degrees. After the set time, the programmable data signal controller 310c starts the motor 308a again, so that the motor 308a can reset the water injection pipe 105 to the position triggered by the infrared sensor 310b after starting.

[0063] It should be noted that the material of the plastic tube 311c is high-density polyethylene. Due to the characteristics of its molecular structure, the high-density polyethylene HDPE tube has certain elasticity and toughness. When it is deformed by external force, it can recover to its original state through its own material properties.

[0064] At the same time, the reset time of the water injection pipe 105 after the second rotation can be manually changed and adjusted through the programmable data signal controller 310c.

[0065] The remaining structure is the same as that of Example 2.

[0066] Example 4 Reference Figures 1 to 11, which is the fourth embodiment of the present invention, is different from the third embodiment in that: a greening irrigation device based on urban management.

[0067] Before irrigating the green vegetation, liquid fertilizer is first injected into the fertilizer box 103, and irrigation water is injected into the water tank 102 at the same time. Then, the hydraulic rod 201 on the mobile frame 101 is activated according to the height of the green vegetation, so that the hydraulic rod 201 can drive the water tank 102 to move after being activated. As the water tank 102 moves, the water supply pipe 204 in the installation groove 203 is driven to move downward. As the water supply pipe 204 moves downward, the one-way solenoid valve 205a is driven to move downward, so that the one-way solenoid valve 205a can pass through the installation ring 2 after moving downward. 05b drives the fixed telescopic hose 205c to move downward, so that the mounting ring 205b can drive the adjusting block 205e to move downward inside the adjusting discharge port 205d through the connecting frame 205f, so that the movement of the adjusting block 205e inside the adjusting discharge port 205d can gradually reduce the amount of liquid fertilizer passing through the adjusting discharge port 205d, and open the one-way solenoid valve 205a when it is necessary to spray the green vegetation, so that the content of liquid fertilizer can also be changed when the spray head 106 at the bottom of the water injection pipe 105 sprays the lower green vegetation.

[0068] When the width of the green vegetation needs to be adjusted, the motor 308a is started, so that the motor 308a can drive the worm 308b to rotate after starting, and the worm 308b can drive the worm wheel 308c supported by the support shaft 308f-1 and the support frame 308f-2 to rotate after the worm wheel 308c rotates, and as the worm wheel 308c rotates, the winding disk 308d supported by the support shaft 308f-1 and the support frame 308f-2 can be driven to rotate, and the winding disk 308d can drive the winding rope 308e to be wound after the winding rope 308e is wound, and as the winding rope 308e is wound, the mounting frame 305 (proportional) can be driven to rotate, and the mounting frame 305 rotates with the cooperation of the movable frame 306 and the fixed pin 307, so that the mounting frame 305 drives the water injection pipe 105 to rotate, so that the rotated water injection pipe 105 can adapt to the width of the green vegetation, and the reset pull rope 309d will be pulled during the rotation of the mounting frame 305.

[0069] As the reset rope 309d is pulled, the fixed disk 309c will be driven to move inside the reset cylinder 309a, so that the fixed disk 309c can drive the reset spring 309b to stretch, so that when the winding rope 308e releases the traction on the mounting frame 305, the reset spring 309b inside the reset cylinder 309a can drive the fixed disk 309c to reset through its own tension, so that the fixed disk 309c can drive the mounting frame 305 to reset through the reset rope 309d.

[0070] After the height and width are adjusted, the water pump 104 is started, and the water pump 104 injects the irrigation water in the water tank 102 into the water supply pipe 204, and the water in the water supply pipe 204 is injected into the fixed pipe 302 through the connecting pipe 303b, and the water in the fixed pipe 302 enters the water injection pipe 105 through the connecting telescopic hose 403, and the water in the water injection pipe 105 can be injected into the sprinkler head 106 through the plastic pipe 311c for spraying. When the water flow in the water supply pipe 204 is injected into the fixed pipe 302 through the connecting pipe 303b, the driving blade 303d is driven to rotate, so that the driving blade 303d can drive the sealing rotating ring 303a to rotate through the transmission frame 303c, and the sealing rotating ring 303a can drive the teeth 303e to rotate after the rotation of the teeth 303e, and the transmission gear 303g can be driven to rotate after the rotation of the teeth 303e, so that the transmission gear 303g can be driven to rotate. After the first transmission rod 303f rotates, the first transmission rod 303f rotates and the universal transmission shaft 303h rotates, so that the universal transmission shaft 303h drives the transmission sleeve 303j to rotate through the sliding transmission rod 303i, so that the transmission sleeve 303j rotates and the second transmission rod 303k rotates, so that the second transmission rod 303k rotates and the transmission bevel gear 303q inside the bellows 303l rotates, so that the transmission bevel gear 303q rotates. After the rotation, the bevel gear rod 303m inside the bellows 303l can be driven to rotate, so that the bevel gear rod 303m can drive the driven bevel gear 303o inside the movable plate 303n to rotate, and the rotation of the driven bevel gear 303o can drive the fan 303p to rotate, so that the fan 303p can blow the air downward after the rotation, so that the airflow blown out from the bellows 303l can change the splashing trajectory of the irrigation water splashing on the outside, thereby reducing the splashing range of the irrigation water to the non-motorized vehicle lane.

[0071] When the water injection pipe 105 encounters a tree during the mobile spraying of vegetation greening, the infrared sensor 310b on the mounting plate 310a will detect it immediately, thereby transmitting the signal to the programmable data signal controller 310c, so that the programmable data signal controller 310c can start the motor 308a again, so that the motor 308a can drive the worm 308b to rotate after it is started again, and the worm 308b can drive the worm wheel 308c supported by the support shaft 308f-1 and the support frame 308f-2 to rotate after the rotation of the worm wheel 308c, and the rotation of the winding disk 308d supported by the support shaft 308f-1 and the support frame 308f-2 can drive the winding disk 308d to rotate, and the winding rope 308e can be wound up after the winding rope 308e is wound up. The roll can drive the mounting frame 305 to rotate again, so that the mounting frame 305 can drive the water injection pipe 105 to fold 90 degrees, so that the 90-degree folded water injection pipe 105 can avoid the trees on the green vegetation, and at the same time, the 90-degree folded water injection pipe 105 can drive the spray head 106 to move through the plastic pipe 311c, so that the plastic pipe 311c will contact the adjustment plate 311b on the positioning frame 311a, so that the adjustment plate 311b can change the direction of the spray head 106 at the bottom of the plastic pipe 311c, so that the spray head 106 is directed toward the green vegetation, so that the water injection pipe 105 can still spray and irrigate the green vegetation after being folded 90 degrees (start the motor 308a again after the set time, so that after the motor 308a is started, the water injection pipe 105 can be reset to the position triggered by the infrared sensor 310b).

[0072] In summary, the height of the spray irrigation is adjusted by the height adjustment mechanism 200 to adapt to the height of different green vegetation for irrigation. At the same time, the width of the spray irrigation is adjusted by the width adjustment mechanism 300 to adapt to the width of different green vegetation for irrigation.
