Description

Technical Field

[0001] This invention relates to the field of garden irrigation, and more specifically to a water-saving irrigation device for garden greening. Background Technology

[0002] Because gardens are large, several irrigation devices are usually installed. These devices are equipped with sprinklers that rotate during irrigation to irrigate the vegetation within their range. To conserve water, the locations of these irrigation devices are designed and planned to ensure that all vegetation and lawns in the garden are irrigated while minimizing water waste.

[0003] However, due to the large area of ​​the garden, and the fact that most of the area consists of low trees and lawns, making it quite open, and the strong winds within the garden, the water sprayed from the sprinklers will move with the wind before landing on the vegetation and lawns during irrigation. The irrigated area will shift a certain distance in the direction of the wind. Since there are many paths for residents to walk on within the garden, when the wind blows from the lawn towards the paths, some of the water sprayed from the sprinklers of the irrigation devices located near the paths will be blown onto the paths with the wind. Nowadays, garden paths are generally paved with materials such as gravel or cement asphalt, which makes it difficult for water to penetrate into the soil and provide it to the vegetation and lawns for absorption, resulting in a waste of irrigation water. Summary of the Invention

[0004] The purpose of this invention is to provide a water-saving irrigation device for landscaping, solving the following technical problems: How to avoid water waste caused by the irrigation area shifting due to wind during irrigation.

[0005] The objective of this invention can be achieved through the following technical solutions: A water-saving irrigation device for landscaping includes a support pipe and an inlet pipe installed inside the support pipe. A first mounting plate is fixedly installed at the upper end of the support pipe; the upper end of the water inlet pipe passes through the first mounting plate; a rotating pipe is rotatably installed on the first mounting plate; the lower end of the rotating pipe is connected to the water inlet pipe; and a plurality of nozzles are installed on the rotating pipe. The first mounting plate is provided with a drive assembly; the drive assembly is used to drive the rotating tube to rotate. A rotating plate is rotatably mounted above the rotating tube; a wind direction rod is fixedly connected above the rotating plate; a wind direction plate is fixedly connected to one side of the wind direction rod; an adjustment assembly is provided below the wind direction plate; the adjustment assembly is used to adjust the spray angle of the nozzle below the wind direction plate according to the wind intensity. As a further embodiment of the present invention: nozzle mounting plates are rotatably provided on both sides of the nozzle; the nozzle mounting plates are fixedly connected to the rotating tube; the rotating tube is connected to one end of the nozzle via a flexible hose. As a further embodiment of the present invention: the adjustment assembly includes two second mounting plates disposed below the wind vane, a connecting rod disposed between the two second mounting plates, a sliding plate slidably disposed on the connecting rod, a second spring disposed between one of the second mounting plates and the sliding plate, an extension rod fixedly disposed below the sliding plate, and a guide rod fixedly disposed below the extension rod; The second mounting plate is located at the end of the wind vane away from the wind vane rod; As a further embodiment of the present invention: one end of the second spring is fixedly connected to the second mounting plate near the wind vane, and the other end of the second spring is fixedly connected to the sliding plate; As a further aspect of the present invention: the middle part of the sliding plate protrudes towards the side away from the wind vane; As a further aspect of the present invention: the connecting rod is a square rod, and the sliding plate has a through hole in the middle for sliding with the connecting rod; As a further aspect of the present invention: the wind vane has a cavity; a cylinder is fixedly connected inside the wind vane cavity; a lifting plate is slidably arranged inside the rotating tube; the output end of the cylinder is fixedly connected to the lifting plate; an annular plate is fixedly connected below the lifting plate; the annular plate is in contact with the inner wall of the rotating tube. As a further embodiment of the present invention: a sampling unit is provided on the second mounting plate; the sampling unit is used to obtain sampling data, and the cylinder is connected to the sampling unit; As a further embodiment of the present invention: the driving assembly includes a motor fixedly disposed below the first mounting plate, a gear rotatably disposed above the first mounting plate, and a gear ring fixedly disposed below the rotating tube; The output end of the motor passes through the first mounting plate and is fixedly connected to the gear, which meshes with the gear ring.

[0006] The beneficial effects of this invention are: (1) In order to avoid water waste caused by the displacement of the irrigation area under the action of wind during irrigation; when the wind blows, the side of the wind vane away from the wind vane moves with the wind to the leeward side of the wind vane under the action of the wind, and the wind vane is parallel to the wind direction; during the movement, the wind vane drives the wind vane and the rotating plate to rotate, and by starting the drive component, the drive component drives the rotating tube to rotate; so that several nozzles rotate with the rotating tube; when the nozzle rotates to one side of the wind vane, the water sprayed by the nozzle blows further away with the wind, and the adjustment component adjusts the spray angle of the nozzle according to the wind intensity, so that the water sprayed by the nozzle remains within the original irrigation range under the action of wind of different intensities, and does not exceed the original irrigation range, and does not spray onto nearby paths, causing water waste; (2) In order to adjust the pitch angle of the nozzle according to the wind intensity, when the wind blows, the wind vane rotates to be parallel to the wind direction; as the wind intensity gradually increases, the force of the wind on the sliding plate gradually increases, and the sliding plate, along with the extension rod, gradually moves along the connecting rod to the end away from the wind vane. Since the end of the nozzle away from the wind vane is inclined; as the nozzle rotates to the bottom of the sliding plate, the guide rod gradually presses the inclined end of the nozzle downward, making the spray angle of the nozzle smaller, so that the spray range is the same as the original spray range under the action of the wind. When the wind intensity is greater, the sliding plate slides a greater distance, and the spray angle of the nozzle rotated to the bottom of the sliding plate is smaller; when the wind intensity is less, the sliding plate slides a smaller distance, and the spray angle of the nozzle rotated to the bottom of the sliding plate gradually approaches the original spray angle, so that the spray angle of the nozzle changes in real time according to the wind intensity; so that the water sprayed by the nozzle is still sprayed within the original irrigation range under the action of wind of different intensities, and will not exceed the original irrigation range, and will not spray onto nearby paths, causing water waste. (3) In order to adjust the position of the ring plate in real time according to the wind intensity, the sampling unit obtains the distance between the sliding plate and the sampling unit, the processing unit processes the distance to determine the distance the cylinder output end moves, and the processing unit controls the cylinder output end to drive the ring plate to move the corresponding distance, so as to adjust the position of the ring plate in real time according to the wind intensity, so that when the nozzle 5 rotates to the windward side of the wind vane 9, it maintains the original irrigation range, so that the vegetation or lawn within the irrigation range can be irrigated.

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] Please see Figures 1-2 As shown, the present invention is a water-saving irrigation device for landscaping, including a support pipe 1 and an inlet pipe 2 disposed inside the support pipe 1; The upper end of the support pipe 1 is fixedly provided with a first mounting plate 3; the upper end of the water inlet pipe 2 passes through the first mounting plate 3; a rotating pipe 4 is rotatably provided on the first mounting plate 3; the lower end of the rotating pipe 4 is connected to the water inlet pipe 2; and a plurality of nozzles 5 are provided on the rotating pipe 4. The first mounting plate 3 is provided with a drive assembly 6; the drive assembly 6 is used to drive the rotating tube 4 to rotate. A rotating plate 7 is rotatably mounted above the rotating tube 4; a wind direction rod 8 is fixedly connected above the rotating plate 7; a wind direction plate 9 is fixedly connected to one side of the wind direction rod 8; an adjustment component 10 is provided below the wind direction plate 9; the adjustment component 10 is used to adjust the spray angle of the nozzle 5 below the wind direction plate 9 according to the wind intensity. To avoid water waste caused by the irrigation area shifting due to wind during irrigation, when the wind blows, the wind vane 9 moves from the side away from the wind vane 8 to the leeward side of the wind vane 8, and the wind vane 9 is parallel to the wind direction. During the movement, the wind vane 9 drives the wind vane 8 and the rotating plate 7 to rotate. By activating the drive assembly 6, the drive assembly 6 drives the rotating tube 4 to rotate, causing several nozzles 5 to rotate with the rotating tube 4. When the nozzles 5 rotate to one side of the wind vane 9, the water sprayed by the nozzles 5 is blown further away by the wind. The adjustment assembly 10 adjusts the spray angle of the nozzles 5 according to the wind intensity, so that the water sprayed by the nozzles 5 remains within the original irrigation range under the action of wind of different intensities, and does not exceed the original irrigation range or spray onto nearby paths, thus avoiding water waste. As one embodiment of the present invention, please refer to Figures 1-2 As shown, nozzle mounting plates 11 are rotatably mounted on both sides of the nozzle 5; the nozzle mounting plates 11 are fixedly connected to the rotating tube 4; the rotating tube 4 is connected to one end of the nozzle 5 via a flexible hose. To facilitate adjustment of the spray angle of the nozzle 5, one end of the nozzle 5 is connected to the rotating tube 4 via a flexible hose. The nozzle 5 is supported by a first spring and a nozzle mounting plate 11. One end of the first spring is fixedly connected to the nozzle 5, and the other end of the first spring is fixedly connected to the rotating tube 4. When the nozzle 5 rotates to below the adjusting assembly 10, the adjusting assembly 10 moves the end of the nozzle 5 away from the rotating tube 4 downward, the first spring is compressed, the spray angle of the nozzle 5 decreases, and the spray range of water decreases. When the nozzle 5 moves out from below the adjusting assembly 10, the first spring drives the end of the nozzle 5 away from the rotating tube 4 back to the initial position, and the nozzle 5 maintains its original spray angle. Please see Figures 3-4 As shown, the adjustment assembly 10 includes two second mounting plates 101 disposed below the wind vane 9, a connecting rod 102 disposed between the two second mounting plates 101, a sliding plate 103 slidably disposed on the connecting rod 102, a second spring 104 disposed between one of the second mounting plates 101 and the sliding plate 103, an extension rod 105 fixedly disposed below the sliding plate 103, and a guide rod 106 fixedly disposed below the extension rod 105. The second mounting plate 101 is located at the end of the wind vane 9 away from the wind vane rod 8; the connecting rod 102 is a square rod, and the middle of the sliding plate 103 has a through hole for sliding with the connecting rod 102; the middle of the sliding plate 103 protrudes to the side away from the wind vane rod 8; one end of the second spring 104 is fixedly connected to the second mounting plate 101 near the wind vane rod 8, and the other end of the second spring 104 is fixedly connected to the sliding plate 103; To adjust the pitch angle of the nozzle 5 according to the wind intensity, when the wind blows, the wind vane 9 rotates to be parallel to the wind direction; when the wind is light, the sliding plate 103 is located at the end of the connecting rod 102 near the wind vane 8, and the second spring 104 is in its natural state. As the wind intensity gradually increases, the force exerted by the wind on the sliding plate 103 gradually increases. Since the connecting rod 102 is parallel to the wind vane 9, the connecting rod 102 is always parallel to the wind direction, and the direction of the force exerted by the wind on the sliding plate 103 is along the connecting rod 102 away from the wind vane 8. On one side; as the wind intensity gradually increases, the force exerted by the wind on the sliding plate 103 gradually increases, and the sliding plate 103 gradually moves along the connecting rod 102 towards the end away from the wind direction rod 8, gradually stretching the second spring 104. The sliding plate 103, along with the extension rod 105, moves towards the end away from the wind direction rod 8. Since the end of the nozzle 5 away from the wind direction rod 8 is inclined; as the nozzle 5 rotates to below the sliding plate 103, the guide rod 106 gradually presses the inclined end of the nozzle 5 downward, making the spray angle of the nozzle 5 smaller. This ensures that the spray range remains the same as the original spray range under the influence of wind. The stronger the wind, the greater the sliding distance of the sliding plate 103, and the smaller the spray angle of the nozzle 5 below the sliding plate 103. Conversely, the weaker the wind, the smaller the sliding distance of the sliding plate 103, and the spray angle of the nozzle 5 below the sliding plate 103 gradually approaches the original spray angle. This allows the spray angle of the nozzle 5 to change in real time according to the wind intensity, ensuring that the water sprayed from the nozzle 5 remains within the original spray range even under wind conditions of varying intensities. Within the irrigation range, the water will not exceed the original irrigation range and will not spray onto nearby paths, thus avoiding water waste. The sliding plate 103 protrudes from the middle to the side away from the wind direction rod 8, allowing the wind to gather in the middle of the sliding plate 103, which facilitates the wind pushing the sliding plate 103 away from the wind direction rod 8. By setting the connecting rod 102 as a square rod, the sliding plate 103 will not rotate when moving on the connecting rod 102, keeping the extension rod 105 and the guide rod 106 directly below the sliding plate 103. Please see Figure 6 As shown, the drive assembly 6 includes a motor 61 fixedly disposed below the first mounting plate 3, a gear 62 rotatably disposed above the first mounting plate 3, and a gear ring 63 fixedly disposed below the rotating tube 4. The output end of the motor 61 passes through the first mounting plate 3 and is fixedly connected to the gear 62, which meshes with the gear ring 63. To drive the rotating tube 4 to rotate, the motor 61 is started. The output end of the motor 61 drives the gear 62 to rotate. The gear 62 drives the rotating tube 4 to rotate on the first mounting plate 3 through the gear ring 63. This allows the nozzle 5 to rotate on the first mounting plate 3 to irrigate the vegetation and lawn in the garden. Please see Figure 3 and Figure 5As shown, the wind vane 8 has a cavity inside; a cylinder 12 is fixedly connected inside the cavity of the wind vane 8; a lifting plate 13 is slidably arranged inside the rotating tube 4; the output end of the cylinder 12 is fixedly connected to the lifting plate 13; an annular plate 14 is fixedly connected below the lifting plate 13; the annular plate 14 is in contact with the inner wall of the rotating tube 4. When the nozzle 5 rotates to the windward side of the wind vane 9, the water sprayed from the nozzle 5 has a reduced range due to the wind, resulting in some vegetation or lawn not being irrigated. By activating the cylinder 12, the output end of the cylinder 12 drives the lifting plate 13 and the annular plate 14 to move downward. Since the bottom of the two ends of the annular plate 14 are at different horizontal heights, the horizontal height below the wind vane 9 is higher than the horizontal height at the other end. Therefore, when the annular plate 14 moves downward, and the nozzle 5 rotates to the windward side of the wind vane 9, the annular plate 14 blocks part of the channel connecting the rotating pipe 4 and the nozzle 5. With the same flow rate, the channel becomes smaller, the pressure in the channel increases, and the flow rate becomes faster, which increases the pressure of the liquid sprayed by the nozzle 5 and increases the range. This allows the nozzle 5 to maintain its original irrigation range when it rotates to the windward side of the wind vane 9, ensuring that the vegetation or lawn within the irrigation range can be irrigated. A sampling unit is provided on one of the second mounting plates 101; the sampling unit is used to acquire sampling data, and the cylinder 12 is connected to the sampling unit. To adjust the position of the annular plate 14 in real time according to the wind intensity, a sampling unit is placed on the second mounting plate 101 away from the wind vane 8 to obtain the distance between the sliding plate 103 and the sampling unit. Specifically, the sampling unit can be an infrared rangefinder. The sampling unit sends the real-time distance to the processing unit. Since the distance between the sampling unit and the sliding plate 103 reflects the wind intensity, the processing unit calculates the distance the output end of the cylinder 12 moves. The processing unit then controls the output end of the cylinder 12 to move the annular plate 14 by the corresponding distance, thus achieving real-time adjustment based on wind intensity. The position of the annular plate 14 is adjusted by the wind speed. When the wind intensity is greater, the distance between the annular plate 14 and the wind direction rod 8 is greater, so that when the nozzle 5 rotates to the windward side of the wind direction plate 9, the area of ​​the channel connecting the rotating pipe 4 and the nozzle 5 blocked by the annular plate 14 is larger. With the same flow rate, the narrower the channel that can flow, the greater the pressure in the channel, the faster the flow rate, and the longer the range. When the wind intensity is greater, the distance between the annular plate 14 and the wind direction rod 8 is closer, so that when the nozzle 5 rotates to the windward side of the wind direction plate 9, the area of ​​the channel connecting the rotating pipe 4 and the nozzle 5 blocked by the annular plate 14 is smaller, the lower the pressure in the channel, the slower the flow rate, and the shorter the range.

[0012] Working principle of the invention: When the wind blows, the wind vane 9, under the influence of the wind, moves from the side away from the wind vane 8 to the leeward side of the wind vane 8, and the wind vane 9 is parallel to the wind direction. During the movement, the wind vane 9 drives the wind vane 8 and the rotating plate 7 to rotate. By starting the motor 61, the output end of the motor 61 drives the gear 62 to rotate. The gear 62 drives the rotating tube 4 to rotate on the first mounting plate 3 through the gear ring 63, causing several nozzles 5 to rotate with the rotating tube 4. When the wind is light, the sliding plate 103 is located at the end of the connecting rod 102 near the wind vane 8, and the second spring 104 is in its natural state. As the wind intensity gradually increases, the force of the wind on the sliding plate 103 gradually increases. Since the connecting rod 102 is parallel to the wind vane 9, the connecting rod 102 is always parallel to the wind direction. Parallel, the direction of the force exerted by the wind on the sliding plate 103 is along the connecting rod 102 towards the side away from the wind direction rod 8; as the wind intensity gradually increases, the force exerted by the wind on the sliding plate 103 gradually increases, and the sliding plate 103 gradually moves along the connecting rod 102 towards the end away from the wind direction rod 8, gradually stretching the second spring 104. The sliding plate 103, along with the extension rod 105, moves towards the end away from the wind direction rod 8. Since the end of the nozzle 5 away from the wind direction rod 8 is inclined; as the nozzle 5 rotates to below the sliding plate 103, the guide rod 106 gradually presses the inclined end of the nozzle 5 downward, making the spray angle of the nozzle 5 smaller, so that the spray range is the same as the original spray range under the action of the wind. When the wind intensity is greater, the sliding plate 103 slides... The greater the distance, the smaller the spray angle of the nozzle 5 below the sliding plate 103; the weaker the wind, the shorter the sliding distance of the sliding plate 103, and the spray angle of the nozzle 5 below the sliding plate 103 gradually approaches the original spray angle, so that the spray angle of the nozzle 5 changes in real time according to the wind intensity; so that the water sprayed by the nozzle 5 remains within the original irrigation range under the action of wind of different intensities, without exceeding the original irrigation range, and without spraying onto nearby paths, thus avoiding water waste; by protruding from the middle of the sliding plate 103 away from the wind direction rod 8, the wind gathers in the middle of the sliding plate 103, making it easier for the wind to push the sliding plate 103 away from the wind direction rod 8; by setting the connecting rod 102... The rod is set to a square shape so that the sliding plate 103 does not rotate when it moves on the connecting rod 102, and the extension rod 105 and the guide rod 106 are kept directly below the sliding plate 103. When the nozzle 5 rotates to the windward side of the wind vane 9, the water sprayed by the nozzle 5 has a reduced range due to the wind, so some vegetation or lawn is not irrigated. The distance between the sliding plate 103 and the sampling unit is obtained through the sampling unit. Since the distance between the sampling unit and the sliding plate 103 can reflect the wind intensity, the processing unit processes the distance to determine the distance the output end of the cylinder 12 moves. The processing unit then controls the output end of the cylinder 12 to drive the annular plate 14 to move the corresponding distance, so as to realize the real-time adjustment of the position of the annular plate 14 according to the wind intensity.By activating cylinder 12, the output end of cylinder 12 drives the lifting plate 13 and the annular plate 14 to move downwards. Because the bottom levels of the two ends of the annular plate 14 are different—the level below the wind vane 9 is higher than the level at the other end—when the annular plate 14 moves downwards, and the nozzle 5 rotates to the windward side of the wind vane 9, the annular plate 14 blocks part of the channel connecting the rotating pipe 4 and the nozzle 5. With the flow rate the same, the channel narrows, the pressure within the channel increases, and the flow velocity increases, causing the liquid pressure sprayed by the nozzle 5 to increase and the range to increase. This allows the nozzle 5 to maintain its original irrigation range when it rotates to the windward side of the wind vane 9, ensuring that the vegetation or lawn within the irrigation range is irrigated.
