Description

Technical Field

[0001] This application relates to the field of municipal greening irrigation technology, and in particular to an automated municipal greening irrigation system. Background Technology

[0002] Green belts are strips of landscaping, usually located in the middle or on both sides of roads. They consist of troughs, shrubs, trees, and other greenery, and are used to separate traffic, beautify the city, and relieve visual fatigue.

[0003] Green belts require regular watering. The common method is to use water trucks, which requires workers to drive to designated watering locations, making it time-consuming and energy-intensive. Alternatively, watering systems can be installed within the green belt for periodic watering. These systems typically include multiple nozzles arranged at intervals along the length of the green belt. When activated, each nozzle sprays water in its surroundings. Because each nozzle's spray area is circular, there is overlap between adjacent nozzles, resulting in more water being sprayed in these overlapping areas. Conversely, less water is sprayed at the edges of the sprayed areas, leading to uneven watering throughout the green belt. Summary of the Invention

[0004] To improve the uniformity of irrigation for green belts, this application provides an automated municipal greening irrigation system.

[0005] The automated municipal greening irrigation system provided in this application adopts the following technical solution:

[0006] An automated municipal greening irrigation system includes a first telescopic rod, a second telescopic rod, a support rod, a movable sprinkler head, and a water replenishment mechanism. Both the first and second telescopic rods are vertically arranged. One end of the support rod is hinged to the first telescopic rod, and the other end is hinged to the second telescopic rod. The support rod is a round rod and is telescopic. The movable sprinkler head has a connecting portion, through which a sliding cavity is formed for the support rod to pass. The water replenishment mechanism includes a water storage tank, a water supply pipe, and a pump. The water storage tank stores water, and both ends of the water supply pipe are connected to the water storage tank and the movable sprinkler head, respectively. A pump is installed in the water supply pipe to deliver water from the water storage tank to the movable nozzle. A first motor is installed at the upper end of the first telescopic rod, and a first take-up roller is fixedly connected to the output end of the first motor. The first take-up roller is connected to a pull rope and is used for winding the pull rope. The other end of the pull rope is connected to the upper end of the second telescopic rod. A guide is installed at the top of the movable nozzle, and the guide has a guide hole for the pull rope to pass through. The central axis of the guide hole is parallel to the central axis of the support rod and is located in different vertical planes.

[0007] By adopting the above technical solution, it is assumed that the initial position of the movable nozzle is located near the first telescopic rod on the support rod. When watering the green belt, the upper end of the first telescopic rod is raised, causing the support rod to tilt. Under its own weight, the movable nozzle slides along the support rod towards the position of the second telescopic rod. At the same time, the first motor is started, which drives the winding roller to rotate periodically in both directions, thereby causing the pull rope to tension and relax periodically. When the pull rope is fully relaxed, the movable nozzle waters the part of the green belt below it. When the pull rope is tensioned, the movable nozzle swings relative to the support rod, watering both sides of the green belt. This allows the movable nozzle to swing while moving linearly back and forth along the length of the green belt, forming a more uniform watering effect on all areas of the green belt and improving the uniformity of watering.

[0008] Optionally, the inner wall of the sliding cavity is rotatably connected with a plurality of balls, which abut against the periphery of the support rod.

[0009] By adopting the above technical solution, rolling friction is generated between the cavity wall of the sliding cavity and the support rod by the ball bearings. This reduces the wear between the cavity wall of the sliding cavity and the support rod, and improves the smoothness of the sliding of the movable nozzle relative to the support rod.

[0010] Optionally, the water replenishment mechanism further includes a first mating component; the first mating component includes a first water replenishment pipe, a sealing airbag, and an energy storage airbag; the movable nozzle has a water cavity, the first water replenishment pipe is disposed on the side wall of the movable nozzle, and the lumen of the first water replenishment pipe is connected to the water cavity; the bottom of the movable nozzle has a plurality of spray nozzles, and the spray nozzles are connected to the water cavity; the energy storage airbag is connected to the upper cavity wall of the water cavity, and there is a gap between the energy storage airbag and the lower cavity wall of the water cavity, and the energy storage airbag is filled with nitrogen; a connector is connected to the lower surface of the energy storage airbag, and the connector passes through the spray nozzle and is connected to the sealing airbag; multiple sealing airbags are provided, and multiple sealing airbags correspond one-to-one with multiple spray nozzles; multiple connectors are provided, and multiple connectors are connected to multiple sealing airbags. The sealing airbags correspond one-to-one; the water supply pipe includes a rigid support pipe, a flexible extension pipe, and a rigid second water supply pipe. The support pipe is used to communicate with the water storage tank, the extension pipe is connected to the end of the support pipe away from the water storage tank, and the second water supply pipe is connected to the end of the extension pipe away from the support pipe; a connecting rod is fixedly connected to the support rod, and the end of the connecting rod away from the support rod is fixedly connected to the second water supply pipe. The central axis of the second water supply pipe is parallel to the central axis of the support rod, and the central axis of the first water supply pipe is collinear with the central axis of the second water supply pipe. The inner diameter of the second water supply pipe is larger than the outer diameter of the first water supply pipe; a third one-way valve is provided in the first water supply pipe, which is used to prevent liquid and gas in the water cavity from flowing from the first water supply pipe to the outside.

[0011] By adopting the above technical solution, when the movable nozzle moves to the end of the support rod, the first water supply pipe connected to the movable nozzle is inserted into the second water supply pipe. At this time, the delivery pump is started, and the delivery pump delivers irrigation water from the storage tank to the water chamber. As the irrigation water enters the water chamber, it compresses the energy storage airbag. The surface of the energy storage airbag facing the nozzle moves upward, simultaneously driving the sealing airbag upward. Several sealing airbags seal several nozzles, allowing the irrigation water entering the water chamber to continue compressing the energy storage airbag in the water chamber. After the delivery pump is turned off, the energy storage airbag gradually returns to its shape. During the return process, it pushes the sealing airbag away from the nozzle, releasing the sealing airbag from the nozzle, and simultaneously pressurizing the irrigation water in the water chamber, pushing the pressurized irrigation water out of the nozzle.

[0012] Optionally, the water replenishment mechanism further includes a second mating component, which includes a storage airbag and a sealing airbag. The storage airbag is disposed on the inner wall of the support tube. The sealing airbag is annularly arranged and disposed on the inner wall of the second water replenishment tube. The outer ring surface of the sealing airbag is connected to the inner wall of the second water replenishment tube, and the inner ring surface of the sealing airbag is used to abut against the outer wall of the first water replenishment tube. The storage airbag is provided with a connecting tube, one end of which is connected to the inner cavity of the storage airbag, and the other end of which is connected to the inner cavity of the sealing airbag.

[0013] By adopting the above technical solution, after the first water supply pipe is inserted into the second water supply pipe, the delivery pump is started. The delivery pump delivers the irrigation water in the water storage tank to the water chamber through the support pipe, extension pipe, and second water supply pipe. During the flow of irrigation water, the gas stored in the storage air bladder is squeezed into the sealing air bladder, so that the inner ring surface of the sealing air bladder is tightly pressed against the outer wall of the first water supply pipe, forming a seal at the interface of the first and second water supply pipes, reducing the possibility of irrigation water spraying out from the second water supply pipe. At the same time, a friction connection is established between the first and second water supply pipes to prevent the movable nozzle from moving along the support rod under water pressure.

[0014] Optionally, the storage airbag is arranged in a ring shape, and the inner ring of the storage airbag is used for water flow.

[0015] By adopting the above technical solution, the irrigation water not only exerts a squeezing force on the wall of the support pipe in the storage airbag during the flow process, but also generates a squeezing force along the length of the support pipe. This allows the gas in the storage airbag to be squeezed into the sealing airbag more quickly, so that the sealing airbag can come into contact with the first water supply pipe more quickly.

[0016] Optionally, the connector has a first ventilation chamber inside, one end of which is connected to the inner cavity of the energy storage airbag, and the other end is connected to the inner cavity of the sealing airbag.

[0017] By adopting the above technical solution, during the process of water entering the water chamber, the water squeezes the sealing airbag, and the gas in the sealing airbag enters the blocking airbag through the first venting chamber, so that the blocking airbag can be tightly pressed against the inner wall of the water nozzle, thereby enhancing the blocking effect of the blocking airbag on the water nozzle.

[0018] Optionally, the guide member has a second venting chamber inside, one end of which communicates with the water chamber, and the other end penetrates the cavity wall of the guide hole; a movable rod is provided in the second venting chamber, and a sealing plate is fixed around the periphery of the movable rod. Along the direction from the cavity wall of the second venting chamber to the side wall of the movable rod, the distance between the surface of the sealing plate near the movable nozzle and the movable nozzle gradually increases; there is a gap between the edge of the sealing plate and the cavity wall of the second venting chamber, and the sum of the radius of the sealing plate and the radius of the movable rod is greater than the radius of the second venting chamber; the end of the movable rod away from the movable nozzle is used for the pull rope to abut; an elastic rope is connected to the end of the movable rod away from the movable nozzle, and when the pull rope is in a taut state, the elastic rope is in a stretched state.

[0019] By adopting the above technical solution, during the tensioning of the pull rope, the pull rope drives the movable rod to move closer to the movable nozzle, and the elastic rope is stretched at the same time; while when the pull rope is in a slack state, the elastic rope restores its deformation, and during the restoration process, it drives the movable rod to move away from the movable nozzle.

[0020] When the movable rod is moved away from the movable nozzle, outside air enters the water chamber through the gap between the edge of the sealing plate and the wall of the second vent chamber. When the movable rod is moved closer to the movable nozzle, the sealing plate unfolds under the impact of the gas in the water chamber, and its edge abuts against the inner wall of the second vent chamber, forming a seal on the water chamber at the position of the second vent chamber. This pressurizes the irrigation water in the water chamber, causing the irrigation water to be sprayed out at a certain pressure at the nozzle position. This supplements the pressurization of the irrigation water by the supplementary air bag, improving the uniformity of irrigation.

[0021] Optionally, a plurality of guide plates are fixed around the periphery of the movable rod, the outer ring surface of the guide plates abutting against the cavity wall of the second ventilation chamber, and the plurality of guide plates are arranged at intervals along the length direction of the movable rod.

[0022] By adopting the above technical solution, multiple contact points are established between the cavity walls of the second ventilation chamber of the movable rod using guide plates, thereby improving the stability of the movable rod sliding relative to the second ventilation chamber.

[0023] Optionally, the end of the movable rod away from the movable nozzle has a through-hole for the pull rope to pass through.

[0024] By adopting the above technical solution, the contact stability between the traction rope and the movable rod is ensured, and the traction rope and the movable rod are prevented from detaching from each other.

[0025] Optionally, a first one-way valve is provided in the second venting chamber. The first one-way valve is located between the movable nozzle and the sealing plate. The first one-way valve is used to prevent gas and liquid in the water chamber from flowing into the second venting chamber.

[0026] By adopting the above technical solution, the gas in the air chamber will not flow back into the second vent chamber regardless of the speed at which the movable rod returns to its original position, thus ensuring that the movable rod has a relatively stable pressure effect on the water being poured into the water chamber.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When watering the green belt, one end of the support rod is raised by the first or second telescopic rod, so that the movable nozzle can slide along the support rod under its own weight. At the same time, the periodic tension and relaxation of the pull rope drives the movable nozzle to swing, forming a more uniform watering in various areas of the green belt and improving the uniformity of watering the green belt.

[0029] 2. By setting up an energy storage airbag in the water cavity, and connecting multiple sealing airbags to the energy storage airbag, and making the inner cavity of the energy storage airbag connected to the inner cavity of the sealing airbag, during the process of replenishing water to the water cavity, the water entering the water cavity squeezes the energy storage airbag, compressing the gas in the energy storage airbag, and at the same time, pushing some of the gas into the sealing airbag to seal the water nozzle; after the water replenishment is completed, the energy storage airbag gradually expands, pressurizing and squeezing out the irrigation water in the water cavity;

[0030] 3. By opening a second venting chamber in the movable nozzle, a movable rod is slidably installed in the second venting chamber, and a sealing plate is installed on the side wall of the movable rod. The movable rod is periodically moved away from and towards the movable nozzle by the pull rope, thereby using the sealing plate to pressurize the gas and irrigation water in the water chamber, so that the irrigation water is pressurized and sprayed out.

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] This application discloses an automated municipal greening irrigation system.

[0043] Example 1

[0044] Reference Figure 1 An automated municipal greening irrigation system includes a first telescopic pole 1, a second telescopic pole 2, a support pole 3, a movable sprinkler head 4, and a water replenishment mechanism 5.

[0045] Both the first telescopic rod 1 and the second telescopic rod 2 are vertically installed, and both are electrically operated telescopic rods. One end of the support rod 3 is hinged to the upper end of the first telescopic rod 1, and the other end is hinged to the upper end of the second telescopic rod 2.

[0046] Reference Figure 2 The support rod 3 is a round rod. The support tube 3 includes a first rod 32 and a second rod 33. One end of the first rod 32 is connected to the first telescopic rod 1, and the other end has a plug hole 34. One end of the second rod 33 is connected to the second telescopic rod 2, and the other end has an integrally formed plug part 35. The plug part 35 is plugged into the plug hole 34 to realize the sliding connection between the first rod 32 and the second rod 33, thereby realizing the telescopic movement of the support rod 3.

[0047] Reference Figure 1 and Figure 3 A first motor 11 is fixed to the upper part of the first telescopic rod 1. A first take-up roller 12 is fixed to the output end of the first motor 11. The first take-up roller 12 is connected to a pull rope 6 and is used for winding the pull rope 6. A second motor 21 is fixed to the upper part of the second telescopic rod 2. A second take-up roller 22 is fixed to the output end of the second motor 21. The end of the pull rope 6 away from the first take-up roller 12 is fixedly connected to the second take-up roller 22.

[0048] Reference Figure 4 and Figure 5 The top of the movable nozzle 4 is connected to a guide member 41, and the guide member 41 has a guide hole 411 through which the pull rope 6 is passed. The central axis of the guide hole 411 is parallel to the central axis of the support rod 3 and is located in a different vertical plane.

[0049] Assume the initial position of the movable nozzle 4 is located at the end of the support rod 3 near the first telescopic rod 1 (or at the end of the support rod 3 near the second telescopic rod 2). When watering the green belt, raise the first telescopic rod 1, causing the support rod 3 to tilt, and the movable nozzle 4 slides along the support rod 3 towards the second telescopic rod 2 under its own weight. Simultaneously with the start of the sliding motion, the first motor 11 and the second motor 21 are activated. The first motor 11 and the second motor 21 drive the first take-up roller 12 and the second take-up roller 22 to rotate periodically in the forward and reverse directions, thereby causing the pull rope 6 to periodically tighten and loosen. The pull rope 6 drives the guide member 41 to swing around the central axis of the support rod 3, thereby causing the movable nozzle 4 to swing during the movement, ensuring that the movable nozzle 4 waters both sides of the green belt. The period of tightening and loosening of the pull rope 6 can be controlled by controlling the rotation speed of the first take-up roller 12 and the second take-up roller 22, thereby controlling the width range of watering by the movable nozzle 4 (when the period is shorter, the swing speed is faster and the width range of watering is larger; when the period is longer, the swing speed is correspondingly smaller and the width range of watering is also smaller).

[0050] It is understood that in other embodiments, only the first motor 11 or only the second motor 21 may be provided, as long as the movable nozzle 4 can be driven to swing by the tension and relaxation of the pull rope 6.

[0051] In this embodiment, a plurality of ball bearings 422 are rolledly connected to the inner wall of the sliding cavity 421. The ball bearings 422 abut against the periphery of the support rod 3, increasing the smoothness of the movement of the movable nozzle 4 relative to the support rod 3.

[0052] Furthermore, in this embodiment, the guide member 41 is threadedly connected to the movable nozzle 4, so that the guide member 41 and the movable nozzle 4 are detachably connected. On the one hand, it is convenient to remove the movable nozzle 4 for maintenance and repair, and on the other hand, the guide member 41 with guide holes 411 opened at different positions can be replaced to control the swing amplitude of the movable nozzle 4.

[0053] The movable nozzle 4 has a connecting part 42 and a spraying part 43, and a sliding cavity 421 is formed through the connecting part 42. The spraying part 43 has a water cavity 432 for storing water and a plurality of spray nozzles 431 for spraying water, and the plurality of spray nozzles 431 are all connected to the water cavity 432.

[0054] Reference Figure 1 and Figure 4 The water supply mechanism 5 includes a water storage tank 51, a water delivery pipe 52, a delivery pump 53, a first mating component 54, and a second mating component 55. The water storage tank 51 is used to store irrigation water. One end of the water delivery pipe 52 is connected to the inner cavity of the water storage tank 51, and the other end is used to connect to the water chamber 432 of the movable nozzle 4. The delivery pump 53 is installed on the water delivery pipe 52 and is used to deliver irrigation water from the water storage tank 51 to the water chamber 432.

[0055] Reference Figure 1 and Figure 6 The water supply pipe 52 includes a rigid support pipe 521, a flexible extension pipe 522, and a rigid second water supply pipe 523. The support pipe 521 is used to communicate with the water storage tank 51, and the delivery pump 53 is installed on the support pipe 521. The extension pipe 522 is connected to the end of the support pipe 521 away from the water storage tank 51 and is spirally wound around the second telescopic rod 2. One end of the second water supply pipe 523 is connected to the end of the extension pipe 522 away from the support pipe 521.

[0056] Reference Figure 4 The support rod 3 is fixedly connected to the connecting rod 31. The end of the connecting rod 31 away from the support rod 3 is fixedly connected to the second water supply pipe 523. The central axis of the connecting rod 31 is perpendicular to the central axis of the support rod 3, and the central axis of the second water supply pipe 523 is parallel to the central axis of the support rod 3.

[0057] The first mating assembly 54 includes a first water supply pipe 541, a sealing airbag 542, and an energy storage airbag 543. The first water supply pipe 541 is disposed on the side wall of the movable nozzle 4, and the cavity of the first water supply pipe 541 is connected to the water cavity 432 of the movable nozzle 4. The central axis of the first water supply pipe 541 is parallel to the central axis of the support rod 3. The central axis of the first water supply pipe 541 is collinear with the central axis of the second water supply pipe 523. The outer diameter of the first water supply pipe 541 is smaller than the inner diameter of the second water supply pipe 523, so that when the movable nozzle 4 slides to the end of the support rod 3 near the second telescopic rod 2, it can be inserted into the second water supply pipe 523.

[0058] Reference Figure 7 A third check valve 544 is installed in the first water supply pipe 541. The third check valve 544 is used to prevent water flow and gas in the water chamber 432 from flowing out of the water chamber 432 to the outside.

[0059] Reference Figure 4 The energy storage bladder 543 is filled with nitrogen. One side of the energy storage bladder 543 is bonded and fixed to the upper wall of the water cavity 432, and the other side is positioned opposite to and spaced from the lower wall of the water cavity 432. A connector 545 is fixed to the surface of the energy storage bladder 543 facing the lower wall of the water cavity 432. The end of the connector 545 away from the energy storage bladder 543 passes through the water nozzle 431 and connects to the sealing bladder 542. Several connectors 545 are provided, and each of the several connectors 545 corresponds to one of the several water nozzles 431. Several sealing bladders 542 are provided, and each of the several sealing bladders 542 corresponds to one of the several connectors 545.

[0060] The connector 545 has a first venting chamber 546 inside. One end of the first venting chamber 546 is connected to the inner cavity of the energy storage bladder 543, and the other end is connected to the inner cavity of the sealing bladder 542. When the energy storage bladder 543 is compressed, the energy storage bladder 543 moves the connector 545 towards the upper cavity wall of the water cavity 432, and forces a portion of the nitrogen gas in the energy storage bladder 543 into the sealing bladder 542, thereby causing the sealing bladder 542 to press tightly against the edge of the water nozzle 431, thus sealing the water nozzle 431.

[0061] Reference Figure 8 The second mating component 55 includes a storage airbag 551 and a sealing airbag 552. The storage airbag 551 is arranged in a ring shape. The outer ring surface of the storage airbag 551 is connected to the inner wall of the support tube 521, and the inner ring is used for water flow. The sealing airbag 552 is arranged in a ring shape. The outer ring surface of the sealing airbag 552 is connected to the inner wall of the second water supply tube 523, and the inner ring surface is used to abut against the outer wall of the first water supply tube 541.

[0062] The storage airbag 551 is provided with a connecting pipe 553, one end of which is connected to the inner cavity of the storage airbag 551, and the other end is connected to the inner cavity of the sealing airbag 552. After the delivery pump 53 is turned on, water flows out from the water storage tank 51 and flows through the support pipe 521, the extension pipe 522, and the second water supply pipe 523 in sequence. When flowing through the support pipe 521, pressure is applied to the storage airbag 551, so that the gas in the storage airbag 551 enters the sealing airbag 552 through the connecting pipe 553, thereby causing the inner ring surface of the sealing airbag 552 to abut against the outer wall of the first water supply pipe 541, achieving a seal at the connection position between the first water supply pipe 541 and the second water supply pipe 523.

[0063] It is understandable that multiple connecting pipes 553 are provided, and the multiple connecting pipes 553 are arranged at intervals around the central axis of the storage air bladder 551 to ensure the flow rate of gas from the storage air bladder 551 into the sealing air bladder 552.

[0064] Furthermore, a second one-way valve 554 is provided at the end of the second water supply pipe 523 furthest from the extension pipe 522. The second one-way valve 554 is used to prevent external debris from entering the water supply pipe 52. It is understood that the second one-way valve 554 has a through hole (not shown in the figure) for the connecting pipe 553 to pass through. The wall of the through hole extends through the periphery of the second one-way valve 554, and the diameter of the through hole should be larger than the outer diameter of the connecting pipe 553 to prevent excessive pulling on the connecting pipe 553 when the second one-way valve 554 is activated.

[0065] Back Figure 1 It is understandable that the water replenishment mechanism 5 is provided in two sets, which are respectively located at the positions of the first telescopic rod 1 and the second telescopic rod 2, so that water can be replenished to the movable nozzle 4 at both ends of the support rod 3. The two extension pipes 522 corresponding to the two sets of water replenishment mechanisms 5 are respectively wound around the first telescopic rod 1 and the second telescopic rod 2.

[0066] It is understandable that the two sets of water replenishment mechanisms 5 can share the same water storage tank 51.

[0067] In this embodiment, the water storage tank 51 includes a tank body 511 and a filter plate 512. The top of the water storage tank 51 is open to form a water inlet 513 for collecting rainwater. The filter plate 512 is disposed on the top of the water storage tank 51 to support the soil while filtering the rainwater entering the water storage tank 51.

[0068] The water storage tank 51 is equipped with a water inlet 514. When the water in the water storage tank 51 is insufficient, water can be manually added through the water inlet 514.

[0069] The first telescopic rod 1, the second telescopic rod 2, the first motor 11, the second motor 21, and the delivery pump 53 are all electrically connected to the control terminal. A humidity detector is buried in the soil and is electrically connected to the control terminal. The humidity detector sends the soil humidity information to the control terminal, which then controls the start and stop of the first telescopic rod 1, the second telescopic rod 2, the first motor 11, the second motor 21, and the delivery pump 53 based on the humidity information.

[0070] The implementation principle of Example 1 is as follows: Taking the initial position of the movable nozzle 4 as an example, where the support rod 3 is close to the first telescopic rod 1, the first water supply pipe 541 is inserted into the second water supply pipe 523. The delivery pump 53 is started, and the delivery pump 53 delivers water from the water storage tank 51 to the water chamber 432 through the support pipe 521, extension pipe 522, second water supply pipe 523 and first water supply pipe 541. During the delivery process, the storage air bladder 551 is squeezed, causing the gas in the storage air bladder 551 to flow into the sealing air bladder 552, thereby causing the inner ring surface of the sealing air bladder 552 to press tightly against the outer wall of the first water supply pipe 541.

[0071] At the same time, water flows into the water chamber 432, squeezing the energy storage bladder 543 in the water chamber 432. On the one hand, it compresses the volume of the gas in the energy storage bladder 543, and on the other hand, it causes a part of the gas in the energy storage bladder 543 to flow into the sealing bladder 542. As the energy storage bladder 543 is compressed, it drives the sealing bladder 542 to come into contact with the water nozzle 431, thus sealing the water nozzle 431.

[0072] When watering the green belt, the first telescopic rod 1 is extended first, causing the upper end of the first telescopic rod 1 to move the support rod 3 upwards near the end of the first telescopic rod 1, thus tilting the support rod 3. This allows the movable nozzle 4 to slide towards the second telescopic rod 2 under its own weight. Simultaneously, the first motor 11 and the second motor 21 are started, driving the first take-up roller 12 and the second take-up roller 22 to rotate periodically in the forward and reverse directions, respectively. This causes the pull rope 6 to tension and relax periodically, and then, through the cooperation of the pull rope 6 and the guide member 41, the movable nozzle 4 swings periodically around the central axis of the support rod 3.

[0073] As the active nozzle 4 slides, the gas in the energy storage bladder 543 causes the energy storage bladder 543 to gradually recover its shape, pressurizing the gas in the water chamber 432 to spray water, thus achieving irrigation.

[0074] Example 2

[0075] Reference Figure 9 The difference between this embodiment and Embodiment 1 is that the structure of the guide member 41 is different. When the movable nozzle 4 is only subjected to its own weight and the supporting force of the support rod 3, that is, when the pull rope 6 is in a slack state, the pull rope 6 is arched.

[0076] In this embodiment, a second ventilation cavity 412 is provided inside the guide member 41. One end of the second ventilation cavity 412 extends to the connecting part 42 and communicates with the water cavity 432, and the other end penetrates the cavity wall of the guide hole 41.

[0077] A movable rod 44 is provided in the second venting cavity 412, and the movable rod 44 can slide along the length of the second venting cavity 412. A sealing sheet 441 made of silicone is fixed to the periphery of the movable rod 44. Along the direction from the cavity wall of the second venting cavity 412 to the side wall of the movable rod 44, the distance between the surface of the sealing sheet 441 near the movable nozzle 4 and the movable nozzle 4 gradually increases, that is, the sealing sheet 441 has an inverted bowl-shaped structure. There is a gap between the edge of the sealing sheet 441 and the cavity wall of the second venting cavity 412, and the sum of the radius of the sealing sheet 441 and the radius of the movable rod 44 is greater than the radius of the second venting cavity 412. When the movable rod 44 is moved away from the movable nozzle 4, outside air enters the water chamber 432 through the gap between the edge of the sealing plate 441 and the cavity wall of the second vent 412. When the movable rod 44 is moved closer to the movable nozzle 4, under the impact of the gas in the water chamber 432, the sealing plate 441 unfolds and its edge abuts against the inner wall of the second vent 412, forming a seal on the water chamber 432 at the position of the second vent 412, thereby pressurizing the irrigation water in the water chamber 432, so that the irrigation water is sprayed out at a certain pressure at the position of the spray nozzle 431, which supplements the pressurization of the irrigation water by the supplementary air bag and improves the uniformity of irrigation.

[0078] In this embodiment, the specific structure and method of sliding the drive rod 44 relative to the second ventilation chamber 412 are as follows: an elastic rope 45 is connected to the end of the drive rod 44 away from the movable nozzle 4. When the elastic rope 45 is at its original length, the pull rope 6 is in a slack state; when the pull rope 6 is in a taut state, the elastic rope 45 is in a stretched state. That is, during the process of the pull rope 6 from slack to taut, the pull rope 6 drives the movable nozzle 4 to swing on one hand, and applies force to the drive rod 44 on the other hand, causing the drive rod 44 to move towards the movable nozzle 4. The elastic rope 45 is pulled, and the moving sealing plate 441 pressurizes the air in the water chamber 432. During the process of the pull rope 6 from taut to slack, the resisting force of the pull rope 6 on the drive rod 44 is removed, the elastic rope 45 returns to its deformation, and drives the drive rod 44 to move away from the movable nozzle 4.

[0079] It is understood that in other embodiments, the movable rod 44 may also be driven to slide relative to the second vent chamber 412 by means of a cylinder or other driving component.

[0080] In this embodiment, the end of the movable rod 44 away from the movable nozzle 4 is provided with a through cavity 442. The through cavity 442 is used for the pull rope 6 to pass through, so as to ensure the contact stability between the pull rope 6 and the movable rod 44 and prevent the pull rope 6 from separating from the movable rod 44.

[0081] In other embodiments, a lobster clip may be provided at the end of the movable rod 44 away from the movable nozzle 4, and the pull rope 6 may be threaded through the lobster clip to facilitate separation of the movable rod 44 from the pull rope 6 without disassembling the pull rope 6. In this case, a passage opening is also provided on the side wall of the guide member 41, which penetrates the cavity wall of the guide hole 41 and is used for the pull rope 6 to pass through, so that the guide member 41 and the pull rope 6 can be separated without disassembling the pull rope 6.

[0082] Furthermore, a first one-way valve 413 is provided in the second venting chamber 412. The first one-way valve 413 is located between the movable nozzle 4 and the sealing plate 441. The first one-way valve 413 is used to prevent gas and liquid in the water chamber 432 from flowing into the second venting chamber 412. This ensures that no matter what speed the movable rod 44 returns to its original position, the gas in the water chamber 432 will not flow back into the second venting chamber 412.

[0083] Furthermore, multiple guide plates 414 are fixed around the periphery of the movable rod 44. The outer ring surface of the guide plates 414 abuts against the cavity wall of the second venting cavity 412. The multiple guide plates 414 are arranged at intervals along the length of the movable rod 44. This establishes multiple contact points between the movable rod 44 and the cavity wall of the second venting cavity 412, thereby improving the stability of the movable rod 44 sliding relative to the second venting cavity 412.

[0084] The implementation principle of Example 2 is as follows: During the movement of the movable nozzle 4 along the support rod 3, the first motor 11 and the second motor 21 drive the pull rope 6 to periodically loosen and tighten, thereby driving the movable nozzle 4 to swing around the central axis of the support rod 3. During the tensioning process of the pull rope 6, the pull rope 6 drives the movable rod 44 to move closer to the movable nozzle 4, and drives the elastic rope 45 to stretch. The sealing plate 441 pressurizes the gas in the water cavity 432, and in turn pressurizes the irrigation water in the water cavity 432, so that the irrigation water is sprayed out at the nozzle 431 at a high speed. During the relaxation process of the pull rope 6, the pull rope 6 no longer applies a force to the movable rod 44 pointing towards the movable nozzle 4. The movable rod 44 moves away from the movable nozzle 4 under the elastic force of the elastic rope 45. Outside air enters the water cavity 432 from between the edge of the sealing plate 441 and the cavity wall of the second vent 412 to replenish the gas in the water cavity 432, which is convenient for the next pressurization.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
