Description

Technical Field

[0001] This invention belongs to the field of greening irrigation technology, and in particular relates to a water-saving irrigation device for landscaping construction. Background Technology

[0002] In the construction and subsequent maintenance of landscaping, sprinkler irrigation is widely used in various green spaces, flower beds, roadside green belts, and landscape areas due to its advantages such as uniform coverage, high degree of automation, and convenient construction and maintenance. Currently, conventional sprinkler systems mostly adopt a fixed nozzle structure, where the spray angle, coverage area, and spray direction are locked after installation and debugging, forming a static sprinkler mode. Under windless or light wind conditions, such devices can basically meet irrigation needs.

[0003] However, landscaping construction sites are mostly open or semi-open environments, making wind interference difficult to avoid. Especially around high-rise buildings, in windy areas, or during seasonal strong winds, the airflow's carrying effect on the sprinkler water is significant. Fixed sprinkler systems cannot dynamically adjust the spray direction and pitch angle, causing lateral or longitudinal drift in the actual spray trajectory. A large amount of irrigation water is scattered into non-target areas, resulting in serious water waste, reduced irrigation efficiency, and uneven irrigation within the target planting area—some areas are water-scarce, while others are overly wet, affecting plant survival rates and growth uniformity. Furthermore, construction sites often require precise irrigation based on soil moisture differences among different plant species and planting modules. Existing fixed systems lack the ability to adjust the spray volume and angle as needed, further exacerbating the ineffective waste of water resources.

[0004] Therefore, developing a water-saving irrigation device that can dynamically adjust the spraying posture according to wind direction and soil moisture is of great significance for improving the efficiency of water resource utilization in landscaping construction. Summary of the Invention

[0005] The purpose of this invention is to provide a water-saving irrigation device for landscaping construction, which aims to solve the problem that the spray position of existing sprinkler devices is not adjustable, and that there is a high-altitude wind effect, resulting in water waste.

[0006] This invention is implemented as follows: a water-saving irrigation device for landscaping construction includes two parallel base plates and a roof fixed to the two base plates by bolts. It also includes: movable bases mounted on the top of each of the two base plates, and concave telescopic frames. The two movable bases move along the length of the two base plates via a walking assembly. A motor is fixed to each of the two movable bases. Both ends of the concave telescopic frame are rotatably connected to the movable bases, and the rotating end of the motor is connected to the rotation center of the concave telescopic frame. A main pipe is located on the top of the concave telescopic frame, one end of which is connected to a water pump via a hose. A nozzle structure is fixed to the side of the concave telescopic frame away from the main pipe. The nozzle structure includes multiple concave rotating frames hinged to the side of the concave telescopic frame away from the main pipe, and these multiple rotating frames are evenly arranged along the length of the concave telescopic frame. Sprayer housings are fixed to the multiple rotating frames. Multiple spray holes are provided at one end of each sprayer housing, and the other end of each sprayer housing is connected to the main pipe via a hose. An angle control assembly for synchronously rotating the multiple sprayer housings is provided on the concave mounting frame.

[0007] A further technical solution includes a concave telescopic frame comprising a concave mounting frame, with rotating rods slidably connected to both ends of the concave mounting frame, and telescopic drive components fixed to both ends of the concave mounting frame. The telescopic ends of the two telescopic drive components are respectively connected to the two rotating rods. The ends of the two rotating rods are rotatably connected to two movable bases, and the rotating ends of the two motors are respectively connected to the rotation centers of the two rotating rods. The main pipe is fixed to the top of the concave mounting frame, and multiple concave rotating frames are hinged to the end of the concave mounting frame away from the main pipe. The multiple concave rotating frames are evenly arranged along the length direction of the concave mounting frame.

[0008] In a further technical solution, the walking component includes a guide rail and a rack fixed on the top of the base plate, the movable base is slidably connected to the guide rail, a second motor is fixed on the movable base, a first gear is fixed on the rotating end of the second motor, and the first gear meshes with the rack.

[0009] In a further technical solution, the angle control component includes a drive plate disposed on the side of the concave mounting bracket near the nozzle housing. The drive plate is slidably disposed along the length direction of the concave mounting bracket. The drive plate is provided with multiple elongated holes. Multiple nozzle housings are each fixedly provided with a transmission slide shaft on the side near the drive plate. The multiple transmission slide shafts are respectively slidably connected in the multiple elongated holes. A telescopic drive component two is fixedly disposed on the concave mounting bracket. The telescopic end of the telescopic drive component two is connected to the drive plate.

[0010] A further technical solution is that a storage shell is fixedly provided at one end of the base plate, and a storage groove is provided on the side of the storage shell away from the base plate, and a cleaning brush is fixedly provided in the storage groove.

[0011] In a further technical solution, the nozzle structure also includes multiple internal rotating housings rotatably connected along their axes within the nozzle housings. Each of the multiple internal rotating housings has multiple notches at one end near the spray hole, and each of the multiple concave rotating frames is provided with a rotating component for driving the internal rotating housing to rotate.

[0012] In a further technical solution, the rotating assembly includes an external gear ring embedded and fixed on the side wall of the internal rotating housing, a clearance groove is provided on the nozzle housing, a motor three is fixed on the nozzle housing, and a gear two is connected to the rotating end of the motor three. The gear two meshes with the external gear ring through the clearance groove.

[0013] A further technical solution also includes a spray control system for adjusting the spray volume and spray angle of the nozzle housing. The spray control system includes:

[0014] The data acquisition module is used to acquire soil moisture, wind speed in the X-axis direction, and wind speed in the Y-axis direction;

[0015] The sprinkler flow module constructs an irrigation flow adjustment model based on soil moisture, outputs the overlap area between the target avoidance groove and the spray hole, and adjusts the current internal rotating shell angle.

[0016] The sprinkler angle adjustment module constructs an irrigation angle adjustment model based on the wind speed in the X-axis and Y-axis directions, outputs the target irrigation angle, and adjusts the current irrigation angle to the target irrigation angle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Dual-axis wind deflection adjustment reduces drift loss. The concave telescopic frame is rotated as a whole by a motor, so that the spray direction of the nozzle forms an angle with the wind direction, which cancels the lateral interference of the wind force in the X-axis. Multiple concave rotating frames are adjusted synchronously by the angle control component to change the pitch angle of the nozzle, suppress the longitudinal deviation of the wind force in the Y-axis, correct the wind-induced spray trajectory deviation, ensure that the irrigation liquid accurately covers the target area, and reduce drift loss.

[0019] 2. Adjust the spray flow rate of the corresponding garden plants according to the soil moisture of different modules, and adjust the spray flow rate of the nozzle housing;

[0020] 3. When not in operation, the device is folded horizontally and stored in the housing to isolate it from external pollution. When the nozzle retracts, the cleaning brush automatically scrapes the spray holes (in conjunction with the swinging of the concave rotating frame) to prevent clogging, reduce maintenance frequency, and extend the service life of the nozzle.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, an embodiment of the present invention provides a water-saving irrigation device for landscaping construction, comprising two parallel base plates 101, a roof fixed to the two base plates 101 by bolts, characterized in that it further comprises: movable bases 102 respectively provided on the top of the two base plates 101, and concave telescopic frames, the two movable bases 102 being movable along the length direction of the two base plates 101 by a walking assembly 2; motors 104 are fixedly mounted on the two movable bases 102, the two ends of the concave telescopic frames are rotatably connected to the movable bases 102, and the rotating end of the motors 104 is connected to the rotation center of the concave telescopic frames; a main pipe 107 is provided on the top of the concave telescopic frames, the... One end of the main pipe 107 is connected to the water pump via a flexible hose. A nozzle structure 3 is fixedly mounted on the side of the concave telescopic frame away from the main pipe 107. The nozzle structure 3 includes multiple concave rotating frames 301 hinged to the end of the concave telescopic frame away from the main pipe 107. The multiple concave rotating frames 301 are evenly arranged along the length of the concave telescopic frame. A nozzle housing 302 is fixedly mounted on the multiple concave rotating frames 301. One end of each of the multiple nozzle housings 302 is provided with multiple spray holes 303. The other end of each of the multiple nozzle housings 302 is connected to the main pipe 107 via a flexible hose. An angle control component 5 is provided on the concave mounting bracket 105 for driving the multiple nozzle housings 302 to rotate synchronously.

[0035] In this embodiment of the invention, during use, the water pump supplies spray liquid into the main pipe 107 through a hose. The spray liquid in the main pipe 107 enters the nozzle housing 302 through the hose and is then sprayed onto the garden plants from the spray hole 303. The walking component 2 drives the concave telescopic frame to move along the length of the two base plates 101, thereby causing the concave telescopic frame to drive the nozzle housing 302 to move along the length of the two base plates 101, thus spraying the garden plants at different locations.

[0036] When the wind blows along the length of the base plate 101 (i.e., in the X-axis wind direction), the spray liquid emitted from the nozzle housing 302 will deviate from the spraying position due to the influence of the X-axis wind direction. At this time, the motor 104 drives the concave telescopic frame to rotate, and the concave telescopic frame drives the nozzle housing 302 to rotate, so that the spraying direction of the nozzle housing 302 forms an angle with the wind direction (e.g., Figure 8 As shown), the spraying state of the nozzle housing 302 is adjusted to correct the spraying position; when the wind blows along the width direction of the base plate 101 (i.e., the Y-axis wind direction), the spraying liquid sprayed from the nozzle housing 302 will also deviate from the spraying position due to the influence of the Y-axis wind direction. At this time, the angle control component 5 drives multiple concave rotating frames 301 to rotate synchronously, and the multiple concave rotating frames 301 drive multiple nozzle housings 302 to rotate synchronously, so that the spraying direction of the nozzle housing 302 forms an angle with the wind direction (e.g., Figure 9 As shown in the figure, the spraying state of the nozzle housing 302 is adjusted and the spraying position is corrected, thereby reducing the waste of irrigation liquid and thus saving water.

[0037] When irrigating garden plants, the height of the concave telescopic frame is adjusted according to the height of the plants, thereby adjusting the spray height. The spray height is also adjusted according to the different growth stages of the plants, thus preventing water loss due to a fixed spray height and achieving water conservation. However, if the height of the concave telescopic frame is too low, causing the spray from the nozzle housing 302 to fail to cover the plants (e.g.), the spray will be insufficient. Figure 10 As shown, the angle control component 5 can drive multiple concave rotating frames 301 to reciprocate synchronously, and the multiple concave rotating frames 301 drive multiple nozzle housings 302 to reciprocate synchronously, thereby increasing the spraying range of the nozzle housings 302.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, in a preferred embodiment of the present invention, the concave telescopic frame includes a concave mounting frame 105. Rotating rods 103 are slidably connected to both ends of the concave mounting frame 105. Telescopic driving members 106 are fixed to both ends of the concave mounting frame 105. The telescopic ends of the two telescopic driving members 106 are respectively connected to the two rotating rods 103. The ends of the two rotating rods 103 are rotatably connected to two movable bases 102. The rotating ends of the two motors 104 are respectively connected to... Two rotating rods 103 are connected at their rotation centers. The main pipe 107 is fixed on the top of the concave mounting bracket 105. Multiple concave rotating brackets 301 are hinged to the end of the concave mounting bracket 105 away from the main pipe 107. The multiple concave rotating brackets 301 are evenly arranged along the length of the concave mounting bracket 105. A storage shell 601 is fixed at one end of the base plate 101. A storage groove 602 is provided on the side of the storage shell 601 away from the base plate 101. A cleaning brush is fixed in the storage groove 602.

[0039] In this embodiment of the invention, the telescopic drive component 106 can be an electric telescopic rod. When adjusting the spray height, the telescopic drive component 106 extends and retracts, causing the concave mounting bracket 105 to move on the rotating rod 103, thereby adjusting the total height of the rotating rod 103 and the concave mounting bracket 105, and thus adjusting the spray height of the nozzle housing 302. After the irrigation of the garden plants is completed, the rotating rod 103 and the concave mounting bracket 105 move to the bottom plate 101 near one end of the receiving housing 601. At this time, the telescopic drive component 106 is in an extended state, and the motor 104 drives the rotating rod 103 and the concave mounting bracket 105 to rotate to a horizontal state. The telescopic drive component 106 retracts, and the telescopic drive component 106 drives the concave mounting bracket 105 towards the receiving slot 602. The concave mounting bracket 105 moves the nozzle housing 302 into the storage slot 602. The concave mounting bracket 105 closes the open end of the side wall of the storage slot 602, thereby storing the nozzle housing 302 and preventing external impurities from adhering to it. When the nozzle housing 302 enters the storage slot 602, its end rests against the cleaning brush. The angle control component 5 drives multiple concave rotating brackets 301 to swing back and forth synchronously. The multiple concave rotating brackets 301 drive multiple nozzle housings 302 to swing back and forth synchronously, thereby moving the nozzle housing 302 on the cleaning brush. The cleaning brush wipes the nozzle housing 302 and cleans one end of the spray hole 303 of the nozzle housing 302, preventing external impurities from solidifying and clogging the spray hole 303.

[0040] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, the walking component 2 includes a guide rail 201 and a rack 202 fixedly mounted on the top of the base plate 101. The movable base 102 is slidably connected to the guide rail 201. A second motor 203 is fixedly mounted on the movable base 102. A first gear 204 is fixedly mounted on the rotating end of the second motor 203. The first gear 204 meshes with the rack 202. A protective cover 205 is fixedly mounted on the top of the base plate 101. The guide rail 201, rack 202, second motor 203 and first gear 204 are all disposed inside the protective cover 205. The protective cover 205 has a long notch along its length to avoid the movable base 102.

[0041] In this embodiment of the invention, when the rotating rod 103 and the concave mounting bracket 105 need to move, the motor 203 drives the gear 204 to rotate. The gear 204 rotates relative to the rack 202, and the rack 202 pushes the rotating gear 204 to move. Under the guidance of the guide rail 201, the gear 204 drives the movable base 102 to move. The movable base 102 drives the rotating rod 103 to move. The rotating rod 103 drives the concave mounting bracket 105 to move. The concave mounting bracket 105 drives the main pipe 107 and the nozzle housing 302 to move, thereby adjusting the spray position of the nozzle housing 302.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the angle control component 5 includes a drive plate 501 disposed on the side of the concave mounting bracket 105 near the nozzle housing 302. The drive plate 501 is slidably disposed along the length direction of the concave mounting bracket 105. The drive plate 501 is provided with a plurality of elongated holes 502. A plurality of the nozzle housings 302 are fixedly provided with a transmission slide shaft 503 on the side near the drive plate 501. The plurality of transmission slide shafts 503 are slidably connected in the plurality of elongated holes 502 respectively. A telescopic drive component 2 504 is fixedly disposed on the concave mounting bracket 105. The telescopic end of the telescopic drive component 2 504 is connected to the drive plate 501.

[0043] In this embodiment of the invention, the second telescopic drive component 504 can be an electric telescopic rod. When adjusting the spray angle of the nozzle housing 302 in the Y-axis direction, the second telescopic drive component 504 extends and retracts. The second telescopic drive component 504 drives the drive plate 501 to move along the length direction of the concave mounting bracket 105. The drive plate 501 pushes the nozzle housing 302 to rotate through the elongated hole 502 and the transmission slide shaft 503. When the nozzle housing 302 rotates, the transmission slide shaft 503 moves within the elongated hole 502. When the second telescopic drive component 504 reciprocates, the nozzle housing 302 can swing back and forth.

[0044] like Figure 5 and Figure 6As shown, in a preferred embodiment of the present invention, the nozzle structure 3 further includes multiple internal rotating housings 304 rotatably connected along their axes within multiple nozzle housings 302. Multiple notches 305 are provided at one end of each internal rotating housing 304 near the spray hole 303. Rotating components 4 for driving the internal rotating housings 304 to rotate are provided on each of the multiple concave rotating frames 301. The rotating component 4 includes an external gear ring 401 embedded and fixed on the side wall of the internal rotating housing 304. A clearance groove 402 is provided on the nozzle housing 302. A motor 403 is fixed on the nozzle housing 302. A gear 404 is connected to the rotating end of the motor 403. The gear 404 meshes with the external gear ring 401 through the clearance groove 402.

[0045] In this embodiment of the invention, garden greening is generally planted in a modular manner using planting trays. Due to differences in location and wind exposure, the soil moisture varies between different modules, meaning the water requirements of the plants in different modules differ. Therefore, it is necessary to adjust the spraying of the garden greening in the corresponding modules, i.e., to adjust the spraying volume of the nozzle housing 302. During garden greening spraying, the spraying liquid in the main pipe 107 enters the inner rotating housing 304 through the hose and nozzle housing 302. The spraying liquid in the inner rotating housing 304 flows from the clearance groove 402 and the spray... When the spray nozzle 303 sprays out and the spray volume of the nozzle housing 302 is adjusted, the motor 3 403 drives the gear 2 404 to rotate, the gear 2 404 drives the outer gear ring 401 to rotate, and the outer gear ring 401 drives the inner rotating housing 304 to rotate. When the inner rotating housing 304 rotates, the clearance groove 402 at the bottom of the inner rotating housing 304 overlaps with the spray nozzle 303 of the nozzle housing 302. The overlapping spray nozzle 303 is the effective spray nozzle. The spray volume of the nozzle housing 302 is adjusted by adjusting the number of effective spray nozzles.

[0046] In a preferred embodiment of the present invention, a spray control system is further included for adjusting the spray volume and spray angle of the nozzle housing 302. The spray control system includes:

[0047] The data acquisition module is used to acquire soil moisture, wind speed in the X-axis direction, and wind speed in the Y-axis direction;

[0048] The sprinkler flow module constructs an irrigation flow adjustment model based on soil moisture, outputs the overlap area between the target avoidance groove and the spray hole, and adjusts the current internal rotating shell angle of 304.

[0049] The sprinkler angle adjustment module constructs an irrigation angle adjustment model based on the wind speed in the X-axis and Y-axis directions, outputs the target irrigation angle, and adjusts the current irrigation angle to the target irrigation angle.

[0050] Among them, soil moisture can be detected and acquired by installing moisture sensors in the soil of different modules, and wind speed in the X-axis direction and wind speed in the Y-axis direction can be detected and acquired by installing ultrasonic wind speed and direction sensors on the concave mounting bracket 105.

[0051] The irrigation flow regulation model is as follows:

[0052]

[0053] in, To avoid the overlap between the clearance groove 402 and the spray hole 303, the overlap area between the clearance groove 402 and the spray hole 303 is adjusted by rotating the motor 403. The overlapping area between the target clearance groove 402 and the spray hole 303. Target soil moisture, Current soil moisture This is the minimum soil moisture threshold.

[0054] The irrigation angle adjustment model is as follows:

[0055]

[0056]

[0057] in, The irrigation angle along the X-axis of the nozzle housing 302 is specifically adjusted by rotating the motor 104. The irrigation angle along the Y-axis of the nozzle housing 302 is specifically adjusted by the telescopic drive component 504. Wind speed along the X-axis. Wind speed along the Y-axis Let be the initial velocity of the water ejected from the nozzle. This is the current pitch angle.

[0058] Derivation of the formula for the irrigation angle adjustment model

[0059] 1. Ideal exercise in calm weather

[0060] After the water droplet is ejected from the nozzle, its horizontal velocity component is: The initial velocity in the vertical direction is Assume the nozzle installation height is... Time it takes for water droplets to fall to the ground Determined by the following formula (taking the positive root):

[0061]

[0062] Under windless conditions, the horizontal displacement of the water droplet is: .

[0063] 2. Drifting in the wind

[0064] When horizontal wind speed exists When the direction is opposite to the direction of the initial horizontal velocity of the nozzle, the actual horizontal displacement of the water droplet is:

[0065]

[0066] To ensure the landing point is the same as in windless conditions (i.e., displacement is zero), the following must be satisfied:

[0067]

[0068] This requires changing the horizontal velocity component of the nozzle, which is actually achieved by deflecting the nozzle's horizontal direction. Let's assume the nozzle deflection angle against the wind. The effective horizontal velocity component is (approximately) When smaller However, a more precise approach is to consider the horizontal velocity vector synthesis.

[0069] 3. Derivation of Vector Compensation

[0070] Let the angle between the nozzle's horizontal inward pointing direction and the headwind direction be... The horizontal headwind velocity component provided by the nozzle is (when When I was very young To completely counteract the wind speed, the following is required:

[0071]

[0072] Therefore:

[0073]

[0074] when When it is smaller (usually less than 30°). (Radian measure), therefore:

[0075]

[0076] The use of arctan instead of a direct approximation is to maintain high accuracy when the angle is large, and the output value of the arctan function is naturally limited to (−90°, 90°), which conforms to physical reality.

[0077] 4. Obtain the final formula

[0078] Decompose wind speed into and , respectively corresponding to horizontal rotation angle and pitch angle Compensation amount:

[0079]
