[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1:

[0039] Reference Figure 1-15A water-saving sprinkler system for garden construction and maintenance includes a sprinkler box 2 and sprinkler heads 3. A rainwater collection device 4 is located at the top of the sprinkler box 2, and a self-cleaning device 5 is located inside the sprinkler box 2. A filter plate 401 is located on the top surface of the sprinkler box 2. The filter plate 401 consists of a fixed plate 503 and multiple rotating cylinders 504. Multiple through holes 519 are equidistantly arranged on the rotating cylinders 504. A cleaning brush 501 is located above the filter plate 401. A rotating shaft 505 is located at one end of each rotating cylinder 504. Gear disks 506 are connected to the rotating shafts 505, and a conveyor belt 507 is located outside the gear disks 506. A drive motor 509 is connected to the end of one rotating shaft 505 furthest from the rotating cylinder 504. A gear disk 506 is located in the middle. A connecting rod 510 is connected to the gear. A rotating gear 511 is provided at the end of the connecting rod 510 away from the gear disk 506. A connecting gear 512 is provided on one side of the rotating gear 511. A connecting rod 513 is provided between the rotating gear 511 and the connecting gear 512. A half gear 514 is connected between the two connecting rods 513. A driving gear 515 is provided between the bottom ends of the two half gears 514. A gear plate 516 is provided at the bottom end of the driving gear 515. A sludge treatment interception cavity 6 is provided at the bottom end of the rotating cylinder 504. The sludge treatment interception cavity 6 is U-shaped. Through holes 601 are provided on both sides of the sludge treatment interception cavity 6. A support plate 517 is provided between two adjacent sludge treatment interception cavities 6. An anti-blocking rod 518 is provided near the through hole 601 on the support plate 517. One end of the support plate 517 is connected to the gear plate 516.

[0040] The through hole 519 is cylindrical and passes through the rotating drum 504 from top to bottom. The two sides of the rotating drum 504 are fitted with the fixed plate 503. The rotating gear 511 meshes with the connecting gear 512, the half gear 514 meshes with the drive gear 515, and the drive gear 515 meshes with the gear plate 516. A limiting rod 508 is provided between two adjacent gear discs 506. The limiting rod 508 is set in the shape of a "door". The two sides of the limiting rod 508 are locked on the outside of the conveyor belt 507. The conveyor belt 507 is wavy in shape. The inside of the conveyor belt 507 meshes with the gear disc 506.

[0041] The bottom end of the sludge treatment interception chamber 6 is provided with multiple filter holes 602 at equal intervals. The bottom end of the sludge treatment interception chamber 6 and inside the spray box 2 is provided with a detachable placement plate 416. The detachable placement plate 416 is provided with a replaceable filter sponge 415.

[0042] In this embodiment, it should be noted that the sprinkler box 2 is placed in the municipal drainage pipe 1 on one side of the garden vegetation planning area, and the bottom of the sprinkler box 2 is not exposed, making the garden planning more aesthetically pleasing.

[0043] When in use, the sprinkler box 2 is placed into the municipal drainage pipe 1. The drainage board at the top of the municipal drainage pipe 1 is cut according to the size of the sprinkler box 2. The sprinkler head 3 is aimed at the planned area of ​​garden vegetation. During irrigation, the sprinkler head 3 draws water from inside the sprinkler box 2 and sprays it onto the planned area of ​​garden vegetation to achieve irrigation.

[0044] A humidity sensor is installed at the top of the spray box 2. In non-rainy weather, the cover cloth 410 and the folding protective plate 502 at the top of the spray box 2 are opened to cover the filter plate 401 at the top of the spray box 2. This prevents external leaves, branches or debris from clogging the filter plate 401, and also covers the spray box 2 to reduce the evaporation of water inside the spray box 2, thus saving water to a certain extent.

[0045] During rainy weather, the humidity sensor detects high air humidity. At this time, the cover cloth 410 and the folding protective plate 502 are folded to expose the filter plate 401. Rainwater enters the spray box 2 through the filter plate 401. Since the top of the spray box 2 is flush with the municipal drainage pipe 1, rainwater can be collected during rainy weather. The rainwater can then be pumped out for irrigation, achieving water-saving effect.

[0046] When the filter plate 401 is exposed, rainwater falls through the through hole 519 at the top of the rotating drum 504, passes through the sludge treatment interception chamber 6, and falls through the through holes 601 and filter holes 502 at the bottom and sides of the sludge treatment interception chamber 6 for the first interception and filtration, which intercepts and processes larger impurities. Then, it passes through the replaceable filter sponge 415 for further filtration of impurities such as mud and sand, making the rainwater collected at the bottom of the spray box 2 relatively clean, avoiding the accumulation of impurities at the bottom of the spray box 2, and also reducing the risk of clogging when the spray head 3 is spraying.

[0047] Since the top of the spray box 2 is flush with the municipal drainage pipe 1, during rainy weather, it is inevitable that mud and sand will accumulate at the through hole 519 of the filter plate 401, which can easily cause blockage. Therefore, during rainy weather, the drive motor 509 on one side inside the spray box 2 is driven back and forth according to the set program by the PLC controller of model "S7-1200". When the drive motor 509 rotates, it drives the connected rotating shaft 505 and gear disk 506 to rotate, which in turn drives the conveyor belt 507 meshing with the outer side of the gear disk 506 to rotate. Due to the limiting rod 508, the contact surface between the conveyor belt 507 and other gear disks 506 is increased, realizing the synchronous rotation of multiple other gear disks 506, which in turn drives multiple rotating drums 506 to rotate 180° synchronously and flip.

[0048] The silt accumulates at the top of the through hole 519. As the rotating drum 506 rotates, the silt will be located at the bottom of the through hole 519. Due to its own weight and the continuous scouring of external rainwater, the silt falls into the silt treatment interception chamber 6. The rainwater remaining in the silt falls downward through the filter hole 602, and the rest of the rainwater flows into the bottom through the two side through holes 601. Due to the splashing of rainwater, some silt will block the two side through holes 601. Therefore, a synchronous drive section is added at the position of the gear disk 506.

[0049] When the drive motor 509 drives multiple gear disks 506 to rotate, the connecting rod 510 connected to one of the gear disks 506 rotates synchronously with the transmission gear 511. The connecting gear 512 meshing with one side of the transmission gear 511 rotates in the opposite direction to the transmission gear 511, thereby driving the two half gears 514 connected to the transmission gear 511 and the connecting gear 512 to rotate in the opposite direction.

[0050] like Figure 12 , Figure 14-15 As shown, the tooth marks of the two half gears 514 alternately mesh with the gear plate 516, thus driving the gear plate 516 to move back and forth. The support plate 517 connected to the gear plate 516 moves back and forth, so the anti-blocking rod 518 set on the support plate 517 will insert into and pull out of the through hole 601 to clear the mud and sand at the position of the through hole 601 and avoid blockage.

[0051] After the rain stops, the cover cloth 410 and the folded protective plate 502 are unfolded. At this time, the cleaning brush 501 located on one side of the folded protective plate 502 brushes the impurities remaining on the top of the filter plate 401.

[0052] like Figure 2 As shown, when the cleaning brush 501 approaches the collection chamber 704, the push rod 7 is inserted into the pre-drilled hole on the spray box 2. The push rod 7 presses the moving rods 702 on both sides of the folding plate 703, and the spring is compressed. At this time, the folding plate 703 is compressed, and impurities are pushed into the collection chamber 704 by the cleaning brush 501 and accumulate. The water stains remaining in the impurities flow into the municipal drainage pipe 1 through the flow holes 705 on both sides. The staff cleans the impurities stored in the collection chamber 704 regularly.

[0053] Example 2:

[0054] Unlike Example 1, referring to Figure 1-8This embodiment further includes the following: the rainwater collection device 4 includes a filter plate 401, uprights 402, a folding advertising board 403, a crossbar 404, a moving groove 405, a lead screw 406, a moving block 407, a threaded block 408, a folding rod 409, a shielding cloth 410, a bevel gear set 411, a drive shaft 412, a dual-output shaft motor 413, and an upright plate 414. The spray head 3 is located on the side of the spray box 2 away from the filter plate 401. Uprights 402 are provided at the top of the spray box 2 and on both the front and rear sides of the filter plate 401. A crossbar 404 is provided between the tops of the two uprights 402 on the same side. A moving groove 405 is provided on the opposite side of the two crossbars 404. A lead screw 406 is provided inside the moving groove 405. 6. Two lead screws 406 are provided with bevel gear sets 411 at the ends away from the spray head 3. The two bevel gear sets 411 are connected to a drive shaft 412 on the opposite side. The drive shaft 412 is connected to a dual-output shaft motor 413 at the end away from the bevel gear set 411. The spray box 2 is provided with a vertical plate 414 at the position of the dual-output shaft motor 413. A folding advertising board 403 is provided between two adjacent vertical rods 402 on the same side. Threaded blocks 408 are provided on the two lead screws 406. Multiple movable blocks 407 are provided on the opposite side of the two crossbars 404. Folding rods 409 are connected to the threaded blocks 408 and the movable blocks 407. A shielding cloth 410 is provided at the top of the folding rod 409. The length of the shielding cloth 410 is greater than the length of the filter plate 401.

[0055] A folding protective plate 502 is provided on the side of the cleaning brush 501 away from the spray head 3.

[0056] A push rod 7 is provided at the bottom of the upright 402 near the spray head 3. A collection chamber 704 is provided at one end of the filter plate 401 in the spray box 2. A folding plate 703 is provided at the top of the collection chamber 704. A moving rod 702 is provided at the bottom of the folding plate 703 near the push rod 7. A spring 706 is provided on the side of the moving rod 702 away from the push rod 7. Flow holes 705 are provided on both sides of the collection chamber 704 in the spray box 2.

[0057] In this embodiment, it should be noted that the unfolding and folding of the shielding cloth 410 is achieved by driving the internal dual-axis motor 413. When the dual-axis motor 413 starts, it drives the transmission shafts 412 on both sides to rotate, which in turn drives the bevel gear set 411 at the end of the transmission shaft 412 to rotate, thereby rotating the lead screw 406 connected to the bevel gear set 411. The threaded block 408 connected to the lead screw 406 moves in the moving groove 405, driving the folding rod 409 to collect and unfold, thereby realizing the folding and unfolding of the shielding cloth 410. At the same time, when the folding rod 409 unfolds, the two uprights 402 connected to the threaded block 408 move synchronously to drive the folding advertising board 403 to unfold. According to the theme of the garden, environmental protection slogans or patterns related to the theme of the garden can be painted on the folding advertising board 403, so that when the folding advertising board 403 is unfolded in non-rainy weather, the sprinkler box 2 becomes a garden landscape, increasing its aesthetics.

[0058] The 406 lead screw is an industrial-grade 316 stainless steel lead screw, suitable for outdoor rain and humid environments, preventing rust after long-term use.

[0059] The drive motor 509 is a "42BYGH48-1.8° stepper motor", the dual-output shaft motor 413 is a "37GB-555 DC geared motor", and the rotary motor 307 is a "25GA-370 DC geared motor".

[0060] All motors should be selected with an IP54 or higher protection rating. For outdoor use, additional waterproof connectors should be installed at the motor wiring terminals to prevent rainwater ingress. A uniform 12V / 24V DC power supply should be used, along with a waterproof power adapter, to ensure outdoor electrical safety. Stepper motors should be paired with corresponding drivers, while DC motors should be connected to the PLC via relays or motor drive modules (such as L298N) to achieve automated control. If used in gardens in coastal areas, due to the high salt and fog environment, stainless steel casing motors or additional anti-corrosion coatings should be selected to improve corrosion resistance.
