Description

Technical Field

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

[0002] A green belt is a strip of land for greening, usually located in the middle or on both sides of the road. It is composed of green plants such as chutes, bushes, and trees. It is used to separate traffic, beautify the city, and relieve visual fatigue.

[0003] Green belts need to be watered regularly. The commonly used watering method is to use a sprinkler truck for regular watering. This method requires staff to drive to the designated watering location for watering, which is time-consuming and energy-consuming. In addition, a watering mechanism can be set up in the green belt and opened regularly for watering. This watering mechanism usually includes multiple nozzles, and the multiple nozzles are arranged at intervals along the length of the green belt. After turning on the nozzle, each nozzle sprays water around itself. Since the spraying range of each nozzle is circular, the watering range between adjacent nozzles has a certain overlapping area, and the overlapping area has a large amount of watering; at the edge of the watering range, the watering amount is relatively small, which leads to uneven watering at various positions of the green belt. Summary of the invention

[0004] In order to improve the uniformity of watering the green belt, the present application provides an automated municipal greening irrigation system.

[0006] By adopting the above technical solution, it is assumed that the initial position of the movable sprinkler is located at the position of the support rod close to the first telescopic rod. When watering the green belt, the upper end of the first telescopic rod is lifted to make the support rod in an inclined state, and the movable sprinkler slides along the support rod to the position of the second telescopic rod under the action of its own gravity; at the same time, the first motor is started, and the first motor is used to drive the winding roller to rotate forward and reverse periodically, thereby driving the pulling rope to be periodically tightened and relaxed. When the pulling rope is completely relaxed, the movable sprinkler waters the part of the green belt below itself, and when the pulling rope is tightened, the movable sprinkler swings relative to the support rod to water the positions on both sides of the green belt, so that the movable sprinkler swings while moving linearly back and forth along the length direction of the green belt, forming a more uniform irrigation for each area of ​​the green belt, thereby improving the uniformity of watering the green belt.

[0007] Optionally, a plurality of balls are rollingly connected to the inner wall of the sliding cavity, and the balls abut against the peripheral side of the support rod.

[0008] By adopting the above technical solution, rolling friction is formed between the cavity wall of the sliding cavity and the support rod by using balls, which on the one hand reduces the wear of the cavity wall of the sliding cavity and the support rod, and on the other hand improves the smoothness of the sliding of the movable nozzle relative to the support rod.

[0009] Optionally, the water replenishment mechanism also includes a first matching component; the first matching component includes a first water replenishment pipe, a blocking airbag and an energy storage airbag; the movable nozzle has a water cavity, the first water replenishment pipe is arranged on the side wall of the movable nozzle, and the tube cavity of the first water replenishment pipe is connected to the water cavity; the bottom of the movable nozzle has a plurality of water spray outlets, and the water spray outlets 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; the lower surface of the energy storage airbag is connected to a connecting piece, and the connecting piece passes through the water spray outlet and is connected to the blocking airbag; a plurality of blocking airbags are provided, and a plurality of the blocking airbags correspond to a plurality of the water spray outlets one by one, and a plurality of connecting pieces are provided, and a plurality of the connecting pieces are connected to a plurality of The blocking airbags correspond one to one; the water delivery 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 tank, the extension pipe is connected to the end of the support pipe away from the water tank, and the second water supply pipe is connected to the end of the extension pipe away from the support pipe; the support rod is fixedly connected with a connecting 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, the central axis of the first water supply pipe is collinear with the central axis of the second water supply pipe, and 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 arranged in the first water supply pipe, and the third one-way valve is used to prevent the liquid and gas in the water cavity from flowing from the first water supply pipe to the outside.

[0010] 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, and the delivery pump is started at this time, and the delivery pump delivers the irrigation water in the water tank to the water cavity. The irrigation water compresses the energy storage airbag while entering the water cavity, and the surface of the energy storage airbag facing the water outlet moves upward, and at the same time drives the blocking airbag to move upward, and several water outlets are blocked by several blocking airbags respectively, so that the irrigation water entering the water cavity can continue to compress the energy storage airbag in the water cavity. After the delivery pump is turned off, the energy storage airbag gradually restores its shape, and during the restoration process, it pushes the blocking airbag to move away from the water outlet, releases the blocking of the water outlet by the blocking airbag, and at the same time pressurizes the irrigation water in the water cavity, and pressurizes the irrigation water out of the water outlet.

[0011] Optionally, the water replenishment mechanism also includes a second mating component, the second mating component includes a storage air bag and a sealing air bag, the storage air bag is arranged on the inner wall of the support tube; the sealing air bag is arranged in a ring shape, the sealing air bag is arranged on the inner wall of the second water replenishment tube, the outer ring surface of the sealing air bag is connected to the inner wall of the second water replenishment tube, and the inner ring surface of the sealing air bag is used to abut against the outer wall of the first water replenishment tube; the storage air bag is provided with a connecting tube, one end of the connecting tube is connected to the inner cavity of the storage air bag, and the other end is connected to the inner cavity of the sealing air bag.

[0012] 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, and the delivery pump delivers the irrigation water in the water tank to the water cavity through the support pipe, the extension pipe and the second water supply pipe. During the flow of the irrigation water, the gas stored in the storage airbag is squeezed into the sealing airbag, so that the inner ring surface of the sealing airbag is tightly against the outer wall of the first water supply pipe, forming a seal at the interface between the first water supply pipe and the second water supply pipe, reducing the possibility of irrigation water spraying out of the second water supply pipe, and also establishing a friction connection between the first water supply pipe and the second water supply pipe to prevent the movable sprinkler from moving along the support rod under the action of water pressure.

[0013] Optionally, the storage airbag is arranged in a ring shape, and the inner ring of the storage airbag is used for water flow to pass through.

[0014] By adopting the above technical solution, the irrigation water not only generates an extrusion pressure on the storage air bag directed toward the tube wall of the support tube during the flow process, but also generates an extrusion pressure along the length direction of the support tube, which can squeeze the gas in the storage air bag into the sealing air bag more quickly, so that the sealing air bag can abut against the first water supply tube more quickly.

[0015] Optionally, a first ventilation cavity is provided inside the connecting member, one end of the first ventilation cavity is connected to the inner cavity of the energy storage airbag, and the other end of the first ventilation cavity is connected to the inner cavity of the blocking airbag.

[0016] By adopting the above technical solution, when the irrigation water enters the water cavity, the irrigation water squeezes the sealing airbag, and the gas in the sealing airbag enters the blocking airbag through the first ventilation cavity, so that the blocking airbag can be tightly against the inner wall of the water spray port, thereby enhancing the blocking effect of the blocking airbag on the water spray port.

[0017] Optionally, a second ventilation cavity is opened inside the guide member, one end of the second ventilation cavity is connected to the water cavity, and the other end passes through the cavity wall of the guide hole; a movable rod is arranged in the second ventilation cavity, a sealing sheet is fixed on the circumference of the movable rod, and along the direction from the cavity wall of the second ventilation cavity to the side wall of the movable rod, the distance between the surface of the sealing sheet close to the movable nozzle and the movable nozzle gradually increases; there is a gap between the edge of the sealing sheet and the cavity wall of the second ventilation cavity, and the sum of the radius of the sealing sheet and the radius of the movable rod is larger than the radius of the second ventilation cavity; the end of the movable rod away from the movable nozzle is used for the pull rope to abut against; the end of the movable rod away from the movable nozzle is connected with an elastic rope, and when the pull rope is in a straight state, the elastic rope is in a stretched state.

[0018] By adopting the above technical solution, in the process of tightening the pulling rope, the pulling rope drives the movable rod to move in the direction close to the movable nozzle, and the elastic rope is stretched at the same time; when the pulling rope is in a relaxed state, the elastic rope restores its deformation, and drives the movable rod to move in the direction away from the movable nozzle during the recovery process.

[0019] When the movable rod is moved in the direction away from the movable nozzle, outside air enters the water cavity from the gap between the edge of the sealing sheet and the cavity wall of the second ventilation cavity; when the movable rod is moved in the direction close to the movable nozzle, under the impact of the gas in the water cavity, the sealing sheet unfolds and the edge abuts against the inner wall of the second ventilation cavity, forming a seal for the water cavity at the position of the second ventilation cavity, thereby applying pressure to the irrigation water in the water cavity, so that the irrigation water is sprayed out at a certain pressure at the position of the water spray port, which supplements the pressure applied to the irrigation water by the supplementary air bag and improves the uniformity of irrigation.

[0020] Optionally, a plurality of guide plates are fixed to the peripheral side of the movable rod, the outer ring surface of the guide plates abuts against the cavity wall of the second ventilation cavity, and the plurality of guide plates are arranged at intervals along the length direction of the movable rod.

[0021] By adopting the above technical solution, a plurality of contact points are established between the cavity walls of the second ventilation cavity of the movable rod by using the guide piece, thereby improving the sliding stability of the movable rod relative to the second ventilation cavity.

[0022] Optionally, a penetration cavity is formed at the end of the movable rod away from the movable nozzle, and the penetration cavity is used for passing the pulling rope.

[0023] By adopting the above technical solution, the abutment stability between the pulling rope and the movable rod is ensured, and the pulling rope and the movable rod are prevented from being separated from each other.

[0024] Optionally, a first one-way valve is provided in the second ventilation cavity, and the first one-way valve is located between the movable nozzle and the sealing sheet, and the first one-way valve is used to prevent the gas and liquid in the water cavity from flowing into the second ventilation cavity.

[0025] By adopting the above technical solution, no matter how fast the movable rod returns to its original position, the gas in the air cavity will not flow back into the second ventilation cavity, ensuring that the movable rod has a relatively stable pressure effect on the irrigation water in the water cavity.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When watering the green belt, one end of the support rod is raised by the first telescopic rod or the second telescopic rod, so that the movable sprinkler can slide along the support rod under the action of its own gravity, and at the same time, the periodic tension and relaxation of the pulling rope is used to drive the movable sprinkler to swing, so that each area of ​​the green belt is watered more evenly, thereby improving the uniformity of watering the green belt; 2. An energy storage airbag is arranged in the water cavity, a plurality of blocking airbags are connected to the energy storage airbag, and the inner cavity of the energy storage airbag is communicated with the inner cavity of the blocking airbag.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-9 This application is described in further detail.

[0038] The embodiment of the present application discloses an automated municipal greening irrigation system.

[0039] Example 1 Reference Figure 1 An automated municipal greening irrigation system includes a first telescopic rod 1, a second telescopic rod 2, a support rod 3, a movable sprinkler 4 and a water replenishment mechanism 5.

[0040] The first telescopic rod 1 and the second telescopic rod 2 are both vertically arranged, and both the first telescopic rod 1 and the second telescopic rod 2 are electric 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.

[0041] 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 is provided with a plug hole 34. One end of the second rod 33 is connected to the second telescopic rod 2, and the other end is integrally formed with a plug portion 35. The plug portion 35 is plugged and matched with the plug hole 34 to achieve a sliding connection between the first rod 32 and the second rod 33, thereby achieving the telescopic support rod 3.

[0042] Reference Figure 1 and Figure 3 A first motor 11 is fixed to the upper part of the first telescopic rod 1, and a first winding roller 12 is fixedly connected to the output end of the first motor 11. The first winding roller 12 is connected to the traction rope 6, and the first winding roller 12 is used for winding the traction rope 6. A second motor 21 is fixed to the upper part of the second telescopic rod 2, and a second winding roller 22 is fixedly connected to the output end of the second motor 21. The end of the traction rope 6 away from the first winding roller 12 is fixedly connected to the second winding roller 22.

[0043] Reference Figure 4 and Figure 5 The top of the movable nozzle 4 is connected with a guide member 41, and the guide member 41 is penetrated with a guide hole 411 for passing the pulling rope 6. The central axis of the guide hole 411 is parallel to the central axis of the support rod 3 and is located in different vertical planes.

[0044] Assume that the initial position of the movable sprinkler 4 is located at one end of the support rod 3 close to the first telescopic rod 1 (it can also be located at one end of the support rod 3 close to the second telescopic rod 2). When watering the green belt, the first telescopic rod 1 is raised to tilt the support rod 3, and the movable sprinkler 4 slides along the support rod 3 toward the second telescopic rod 2 under the action of its own gravity. The first motor 11 and the second motor 21 are started at the same time when sliding begins, and the first motor 11 and the second motor 21 are used to drive the first winding roller 12 and the second winding roller 22 to rotate forward and reverse periodically respectively, thereby driving the pulling rope 6 to be periodically tightened and relaxed, and the pulling rope 6 drives the guide member 41 to swing around the central axis of the support rod 3, thereby driving the movable sprinkler 4 to swing during the movement, so as to ensure that the movable sprinkler 4 irrigates both sides of the green belt. The tensioning and relaxing cycle of the pulling rope 6 can be controlled by controlling the rotation speed of the first winding roller 12 and the second winding roller 22, thereby controlling the width range of irrigation of the movable sprinkler 4 (when the cycle is short, the swinging speed is fast and the width range of irrigation is large; when the cycle is long, the swinging speed is correspondingly small and the width range of irrigation is also small).

[0045] It is understandable 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 pulling rope 6 .

[0046] In this embodiment, a plurality of balls 422 are rollingly connected to the inner wall of the sliding cavity 421 , and the balls 422 abut against the peripheral side of the support rod 3 , thereby increasing the smoothness of the movement of the movable nozzle 4 relative to the support rod 3 .

[0047] Furthermore, in the present embodiment, the guide member 41 is threadedly connected to the movable nozzle 4 so that the guide member 41 and the movable nozzle 4 can be detachably connected. On the one hand, it is convenient to remove the movable nozzle 4 for maintenance and overhaul; on the other hand, the guide member 41 with the guide hole 411 at different positions can also be replaced to control the swing amplitude of the movable nozzle 4.

[0048] The movable nozzle 4 has a connecting portion 42 and a spraying portion 43, and the sliding cavity 421 is opened through the connecting portion 42. The spraying portion 43 has a water cavity 432 for storing water and a plurality of water spraying ports 431 for spraying water, and the plurality of water spraying ports 431 are all connected to the water cavity 432.

[0049] Reference Figure 1 and Figure 4 The water replenishment mechanism 5 includes a water tank 51, a water pipe 52, a delivery pump 53, a first matching component 54 and a second matching component 55. The water tank 51 is used to store irrigation water. One end of the water pipe 52 is connected to the inner cavity of the water tank 51, and the other end is used to communicate with the water cavity 432 of the movable sprinkler 4. The delivery pump 53 is installed on the water pipe 52, and the delivery pump 53 is used to deliver the irrigation water in the water tank 51 to the water cavity 432.

[0050] Reference Figure 1 and Figure 6 The water delivery 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 arranged on the support pipe 521. The extension pipe 522 is connected to one end of the support pipe 521 away from the water storage tank 51 and spirally wound around the second telescopic rod 2. One end of the second water supply pipe 523 is connected to one end of the extension pipe 522 away from the support pipe 521.

[0051] Reference Figure 4 The support rod 3 is fixedly connected to a connecting rod 31, and one 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.

[0052] The first matching component 54 includes a first water supply pipe 541, a blocking airbag 542 and an energy storage airbag 543. The first water supply pipe 541 is arranged on the side wall of the movable sprinkler 4, the tube cavity of the first water supply pipe 541 is connected with the water cavity 432 of the movable sprinkler 4, and 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, and 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 the movable sprinkler 4 can be inserted into the second water supply pipe 523 when it slides to the end of the support rod 3 close to the second telescopic rod 2.

[0053] Reference Figure 7 A third one-way valve 544 is installed in the first water supply pipe 541, and the third one-way valve 544 is used to prevent the water flow and gas in the water cavity 432 from leaving the water cavity 432 to the outside.

[0054] Reference Figure 4 , the energy storage airbag 543 is filled with nitrogen. One side of the energy storage airbag 543 is bonded and fixed to the upper wall of the water cavity 432, and the other side is arranged opposite to the lower wall of the water cavity 432 and has a gap. A connector 545 is fixed to the surface of the energy storage airbag 543 facing the lower wall of the water cavity 432, and one end of the connector 545 away from the energy storage airbag 543 passes through the water outlet 431 and is connected to the blocking airbag 542. There are a plurality of connectors 545, and the plurality of connectors 545 correspond to the plurality of water outlets 431. There are a plurality of blocking airbags 542, and the plurality of blocking airbags 542 correspond to the plurality of connectors 545.

[0055] The connecting member 545 has a first vent cavity 546 formed therein, one end of the first vent cavity 546 is connected to the inner cavity of the energy storage airbag 543, and the other end is connected to the inner cavity of the blocking airbag 542. When the energy storage airbag 543 is compressed, the energy storage airbag 543 drives the connecting member 545 to move toward the upper cavity wall of the water cavity 432, and presses a portion of the nitrogen in the energy storage airbag 543 into the blocking airbag 542, thereby driving the blocking airbag 542 to press against the edge of the water spout 431, thereby blocking the water spout 431.

[0056] Reference Figure 8 The second matching component 55 includes a storage airbag 551 and a sealing airbag 552. The storage airbag 551 is arranged in an annular 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 to pass through. The sealing airbag 552 is arranged in an annular shape. The outer ring surface of the sealing airbag 552 is connected to the inner wall of the second water supply pipe 523, and the inner ring surface is used to abut against the outer wall of the first water supply pipe 541.

[0057] 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 of 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, the water applies pressure to the storage airbag 551, so that the gas in the storage airbag 551 enters the sealing airbag 552 through the connecting pipe 553, so that the inner ring surface of the sealing airbag 552 abuts against the outer wall of the first water supply pipe 541, so as to achieve sealing at the connection position between the first water supply pipe 541 and the second water supply pipe 523.

[0058] It can be understood that there are multiple connecting tubes 553 , and the multiple connecting tubes 553 are arranged at intervals around the central axis of the storage airbag 551 to ensure the flow rate of gas flowing from the storage airbag 551 into the sealing airbag 552 .

[0059] Furthermore, a second one-way valve 554 is provided at the end of the second water supply pipe 523 away from the extension pipe 522, and the second one-way valve 554 is used to prevent external debris from entering the water delivery pipe 52. It can be understood that the second one-way valve 554 is provided with a through hole (not shown in the figure) for the connecting pipe 553 to pass through, and the hole wall of the through hole passes through the circumference of the second one-way valve 554, and the hole diameter of the through hole should be larger than the outer diameter of the connecting pipe 553, so as to prevent the second one-way valve 554 from causing excessive pulling on the connecting pipe 553 when it is activated.

[0060] Back to Figure 1 It can be understood that two groups of water replenishment mechanisms 5 are provided, and the two groups of water replenishment mechanisms 5 are respectively provided at the positions of the first telescopic rod 1 and the second telescopic rod 2, so that the movable nozzle 4 can be replenished with water at both ends of the support rod 3. The two extension pipes 522 corresponding to the two groups of water replenishment mechanisms 5 are respectively wound around the first telescopic rod 1 and the second telescopic rod 2.

[0061] It is understandable that the two groups of water replenishment mechanisms 5 can share the same water storage tank 51 .

[0062] In this embodiment, the water tank 51 includes a box body 511 and a filter plate 512. The top of the water tank 51 is open to form a water collection port 513 for collecting rainwater. The filter plate 512 is arranged on the top of the water tank 51 to support the soil and filter the rainwater entering the water tank 51.

[0063] The water storage tank 51 is provided with a water filling port 514 , and when the amount of water in the water storage tank 51 is insufficient, water is artificially replenished through the water filling port 514 .

[0064] 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, which is electrically connected to the control terminal and sends the soil humidity information to the control terminal. The control terminal 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 according to the humidity information.

[0065] The implementation principle of Example 1 is as follows: the initial position of the movable nozzle 4 is located at the position of the support rod 3 close to the first telescopic rod 1. At this time, the first water supply pipe 541 is inserted into the second water supply pipe 523, and the delivery pump 53 is started. The delivery pump 53 delivers the water in the water tank 51 to the water cavity 432 through the support pipe 521, the extension pipe 522, the second water supply pipe 523 and the first water supply pipe 541. During the delivery process, the storage airbag 551 is squeezed, so that the gas in the storage airbag 551 flows into the sealing airbag 552, and then the inner ring surface of the sealing airbag 552 is tightly against the outer wall of the first water supply pipe 541.

[0066] At the same time, water flows into the water cavity 432, squeezing the energy storage airbag 543 in the water cavity 432. On the one hand, the volume of the gas in the energy storage airbag 543 is compressed, and on the other hand, a part of the gas in the energy storage airbag 543 flows into the blocking airbag 542. When the energy storage airbag 543 is compressed, it drives the blocking airbag 542 to abut against the water outlet 431, thereby blocking the water outlet 431.

[0067] When watering the green belt, first extend the first telescopic rod 1, so that the upper end of the first telescopic rod 1 drives the support rod 3 to move up near the end of the first telescopic rod 1, so that the support rod 3 is tilted, so that the movable sprinkler 4 can slide toward the direction of the second telescopic rod 2 under the action of its own gravity. At the same time, start the first motor 11 and the second motor 21, and use the first motor 11 and the second motor 21 to drive the first winding roller 12 and the second winding roller 22 to rotate forward and reverse periodically, thereby driving the pull rope 6 to be periodically tightened and relaxed, and then through the cooperation of the pull rope 6 and the guide member 41, drive the movable sprinkler 4 to swing periodically with the central axis of the support rod 3 as the axis.

[0068] While the movable nozzle 4 slides, the gas in the energy storage airbag 543 drives the energy storage airbag 543 to gradually restore its deformation, pressurizes the gas in the water cavity 432 to spray water, and realizes irrigation.

[0069] Example 2 Reference Fig. 9 The difference between this embodiment and the first embodiment is that the structure of the guide member 41 is different. When the movable spray head 4 is only subjected to its own gravity and the support force of the support rod 3, that is, when the pulling rope 6 is in a relaxed state, the pulling rope 6 is in an arched shape.

[0070] In this embodiment, a second ventilation cavity 412 is defined inside the guide member 41 , one end of the second ventilation cavity 412 extends to the connecting portion 42 and communicates with the water cavity 432 , and the other end passes through the cavity wall of the guide hole 41 .

[0071] A movable rod 44 is provided in the second ventilation cavity 412, and the movable rod 44 can slide along the length direction of the second ventilation cavity 412. A sealing sheet 441 made of silicone is fixed to the peripheral side of the movable rod 44, and along the direction from the cavity wall of the second ventilation cavity 412 to the side wall of the movable rod 44, the distance between the surface of the sealing sheet 441 close to the movable nozzle 4 and the movable nozzle 4 gradually increases, that is, the sealing sheet 441 is an inverted bowl-shaped structure. There is a gap between the edge of the sealing sheet 441 and the cavity wall of the second ventilation 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 ventilation cavity 412. When the movable rod 44 is moved in the direction away from the movable sprinkler 4, outside air enters into the water cavity 432 from the gap between the edge of the sealing sheet 441 and the cavity wall of the second ventilation cavity 412; when the movable rod 44 is moved in the direction close to the movable sprinkler 4, under the impact of the gas in the water cavity 432, the sealing sheet 441 is unfolded and the edge abuts against the inner wall of the second ventilation cavity 412, forming a seal for the water cavity 432 at the position of the second ventilation cavity 412, thereby applying pressure to the irrigation water in the water cavity 432, so that the irrigation water is sprayed out at a certain pressure at the position of the water spray port 431, which supplements the pressure applied to the irrigation water by the supplementary air bag and improves the uniformity of irrigation.

[0072] In this embodiment, the specific structure and method of driving the movable rod 44 to slide relative to the second ventilation cavity 412 are as follows: the end of the movable rod 44 away from the movable nozzle 4 is connected with an elastic rope 45, when the elastic rope 45 is at its original length, the pulling rope 6 is in a relaxed state, and when the pulling rope 6 is in a stretched state, the elastic rope 45 is in a stretched state. That is, in the process of the pulling rope 6 from being relaxed to being stretched, the pulling rope 6 drives the movable nozzle 4 to swing on the one hand, and exerts force on the movable rod 44 on the other hand, so that the movable rod 44 moves in a direction close to the movable nozzle 4, the elastic rope 45 is pulled, and the moving sealing sheet 441 pressurizes the air in the water cavity 432; in the process of the pulling rope 6 from being stretched to being relaxed, the contact force of the pulling rope 6 on the movable rod 44 is removed, the elastic rope 45 recovers its deformation, and drives the movable rod 44 to move in a direction away from the movable nozzle 4.

[0073] It is understandable that, in other embodiments, the movable rod 44 may be driven to slide relative to the second ventilation cavity 412 by providing a cylinder or other driving member.

[0074] In this embodiment, a through cavity 442 is formed at the end of the movable rod 4 away from the movable nozzle 4. The through cavity 442 is used for the pulling rope 6 to pass through, so as to ensure the abutment stability between the pulling rope 6 and the movable rod 44 and prevent the pulling rope 6 and the movable rod 44 from detaching from each other.

[0075] In other embodiments, a lobster clasp may be provided at the end of the movable rod 44 away from the movable nozzle 4, and the pulling rope 6 is passed through the lobster clasp, so that the movable rod 44 and the pulling rope 6 can be separated from each other without removing the pulling rope 6. In this case, a through hole is also provided on the side wall of the guide member 41, and the through hole penetrates the cavity wall of the guide hole 41, and the through hole is used for the pulling rope 6 to pass through, so that the guide member 41 and the pulling rope 6 can be separated from each other without removing the pulling rope 6.

[0076] Furthermore, a first one-way valve 413 is provided in the second ventilation cavity 412, and the first one-way valve 413 is located between the movable nozzle 4 and the sealing sheet 441. The first one-way valve 413 is used to prevent the gas and liquid in the water cavity 432 from flowing into the second ventilation cavity 412. Therefore, no matter how fast the movable rod 44 returns to its original position, the gas in the water cavity 432 will not flow back into the second ventilation cavity 412.

[0077] Furthermore, a plurality of guide pieces 414 are fixed to the peripheral side of the movable rod 44, and the outer ring surface of the guide piece 414 abuts against the cavity wall of the second ventilation cavity 412, and the plurality of guide pieces 414 are arranged at intervals along the length direction of the movable rod 44. The guide pieces 414 are used to establish a plurality of abutment points between the cavity wall of the second ventilation cavity 412 of the movable rod 44, thereby improving the sliding stability of the movable rod 44 relative to the second ventilation cavity 412.

[0078] The implementation principle of Example 2 is: when the movable nozzle 4 moves along the support rod 3, the first motor 11 and the second motor 21 are used to drive the pulling rope 6 to relax and tighten periodically, thereby driving the movable nozzle 4 to swing around the central axis of the support rod 3. In the process of tensioning the pulling rope 6, the pulling rope 6 drives the movable rod 44 to move toward the movable sprinkler 4, and drives the elastic rope 45 to stretch, and uses the sealing sheet 441 to pressurize the gas in the water cavity 432, and then pressurizes the irrigation water in the water cavity 432, so that the irrigation water is sprayed out at a higher speed at the water spray port 431; in the process of the pulling rope 6 recovering relaxation, the pulling rope 6 no longer applies a force directed to the movable sprinkler 4 on the movable rod 44, and the movable rod 44 moves in the direction away from the movable sprinkler 4 under the elastic force of the elastic rope 45, and the outside air enters the water cavity 432 from between the edge of the sealing sheet 441 and the cavity wall of the second ventilation cavity 412 to replenish the gas in the water cavity 432, so as to facilitate the next pressure application.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
