Description

Technical Field

[0001] This utility model relates to the field of greening maintenance technology, and in particular to a water-saving micro-irrigation device for greening maintenance. Background Technology

[0002] Green space maintenance, encompassing watering, pruning, weeding, pesticide application, and replanting after the completion of green space construction, is a simple yet essential and crucial task. Poor maintenance can prevent the preservation of costly landscaped gardens, leading to rapid grassland degradation, tree death, and overgrown weeds. Currently, some green areas have water pipes with several drainage holes for irrigation. However, these existing pipes are prone to clogging with soil and gravel, affecting irrigation efficiency.

[0003] Chinese utility model patent CN216088077U discloses a water-saving multifunctional micro-irrigation system, including a water tank and a water pump. The water pump has a connecting pipe on its side, a water pipe at the lower end of the connecting pipe, and an outlet pipe on its side. The outlet pipe has a number of through holes arranged in a linear array. The outlet pipe has a protective sleeve on its outer surface. The outlet pipe and the protective sleeve are fitted together and are movably connected. The right end of the protective sleeve has a positioning ring on its outer surface and is fixedly connected. The fixing ring has a positioning groove on its inner side. The positioning ring and the positioning groove are fitted together and are movably connected. When irrigation is not required, the protective sleeve can seal the through holes to prevent mud and sand from entering and clogging them.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Before pouring, the above-mentioned device requires workers to move the protective sleeve to ensure that the No. 1 through hole is not blocked; after pouring, workers need to move the protective sleeve to block the No. 1 through hole, which is inconvenient to operate. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a water-saving micro-irrigation device for greening maintenance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water-saving micro-irrigation device for greening maintenance, comprising an installation pipe, a connecting plate at one end of the installation pipe, a connection port on the connecting plate, the connection port being connected to an external water source, an installation plate on the side of the installation pipe away from the connecting plate, a through hole in the middle of the installation plate, a protective pipe at the sliding hole of the installation plate, a plurality of first through holes spaced apart on the protective pipe, a water outlet pipe slidably disposed inside the protective pipe, a second through hole spaced apart on the water outlet pipe, an installation ring at one end of the water outlet pipe inside the installation pipe, an annular groove on the outer wall of the installation ring, a rubber sealing ring disposed inside the annular groove, the rubber sealing ring abutting against the inner wall of the installation pipe, and a compression spring sleeved on the body of the water outlet pipe between the installation plate and the installation ring.

[0007] By adopting the above technical solution, an installation pipe, installation plate, protective pipe, installation ring, and compression spring are installed. In the initial state, the compression spring pushes the installation ring and the outlet pipe with its elastic force, causing the second through hole and the first through hole to separate. At this time, the protective pipe blocks the second through hole, preventing mud and sand from entering the outlet pipe through the second through hole or remaining in the second through hole, thus affecting the water output. During irrigation, the external water source is activated, and the external water source enters the installation pipe through the connection port. Under the action of water pressure, the installation ring and the outlet pipe are pushed to move, making the second through hole and the first through hole concentric, allowing water to flow out through the second through hole and the first through hole to irrigate the surrounding greenery. When the installation ring moves, the compression spring is compressed. When the external water source is turned off, the compression spring loses its restraint and pushes the installation ring and the outlet pipe back to their original positions under the action of its elastic force, and the first through hole and the second through hole are misaligned. The protection of the second through hole is automatically opened and closed according to the external water source, reducing the need for manual operation and making it more convenient. Furthermore, water can only flow out through the second and first through holes, resulting in less water consumption and saving water resources.

[0008] Furthermore, two stops are provided circumferentially at intervals inside the mounting tube.

[0009] By adopting the above technical solution, two blocks are circumferentially spaced inside the installation tube. In the initial state, the blocks are in contact with the installation ring, thus restricting the position of the installation ring.

[0010] Furthermore, the stop block is provided with a sliding hole, the length direction of which is consistent with the length direction of the water outlet pipe, and a sliding rod is slidably disposed in the sliding hole, the sliding rod being connected to the side of the mounting ring away from the water outlet pipe.

[0011] By adopting the above technical solution, sliding holes and sliding rods are set to restrict the installation ring and water outlet pipe, so that they can only slide and cannot rotate, thus preventing the first through hole and the second through hole from being misaligned in the circumferential direction, which would cause the first through hole and the second through hole to become out of concentricity after the water outlet pipe slides.

[0012] Furthermore, a baffle is provided at the end of the slide rod away from the mounting ring.

[0013] By adopting the above technical solution, a baffle is set at the end of the slide rod away from the mounting ring. The movement of the water outlet pipe and the mounting ring drives the slide rod to move. When the baffle contacts the stop block, the water outlet pipe cannot continue to slide outward, thus limiting the sliding distance of the water outlet pipe and ensuring that the second through hole and the first through hole can be concentric.

[0014] Furthermore, the distance between two adjacent first through holes is the same as the distance between two adjacent second through holes.

[0015] By adopting the above technical solution, the distance between two adjacent first through holes is set to be consistent with the distance between two adjacent second through holes, ensuring that after the water outlet pipe is moved, each first through hole and its corresponding second through hole can be concentric.

[0016] Furthermore, the diameter of the first through hole is larger than the diameter of the second through hole.

[0017] By adopting the above technical solution, the diameter of the first through hole is set to be larger than the diameter of the second through hole. The larger diameter of the first through hole avoids clogging by sand and gravel.

[0018] Furthermore, the inner wall of the protective pipe is provided with a first mounting groove corresponding to the first through hole, and a first rubber ring is provided in the first mounting groove, which abuts against the outer wall of the water outlet pipe.

[0019] By adopting the above technical solution, a first mounting groove and a first rubber ring are set up so that when external sand and gravel are in the first through hole, they cannot enter the gap between the protective pipe and the water outlet pipe.

[0020] Furthermore, a second mounting groove is provided on the outer wall of the water outlet pipe corresponding to the second through hole, and a second rubber ring is provided in the second mounting groove, which abuts against the inner wall of the protective pipe.

[0021] By adopting the above technical solution, a second mounting groove and a second rubber ring are provided to prevent water from entering the gap between the protective pipe and the outlet pipe.

[0022] Furthermore, the diameter of the through hole is consistent with the inner diameter of the protective tube.

[0023] Furthermore, a base is provided at the bottom of the mounting tube, and four ground nails are provided at the bottom of the base, arranged in a rectangular array.

[0024] By adopting the above technical solution, the ground nails are driven into the soil to fix the position of the base and the mounting pipe.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. This application includes an installation pipe, installation plate, protective pipe, installation ring, and compression spring. In the initial state, the compression spring, through its elastic force, pushes the installation ring and the outlet pipe, causing the second through hole and the first through hole to separate. At this time, the protective pipe blocks the second through hole, preventing mud and sand from entering the outlet pipe through the second through hole or remaining in the second through hole, thus affecting the water output. During irrigation, an external water source is activated, and the external water source enters the installation pipe through the connection port. Under water pressure, the installation ring and the outlet pipe are pushed and moved, making the second through hole and the first through hole concentric, allowing water to flow out through the second through hole and the first through hole to irrigate the surrounding greenery. When the installation ring moves, the compression spring is compressed. When the external water source is turned off, the compression spring loses its restraint and, under its elastic force, pushes the installation ring and the outlet pipe back to their original positions, causing the first and second through holes to separate. The protection of the second through hole is achieved by automatically opening and closing according to the external water source, reducing operator intervention and making it more convenient. Furthermore, water can only flow out through the second and first through holes, resulting in less water consumption and saving water resources.

[0027] 2. In this application, sliding holes and sliding rods are provided to restrict the installation ring and water outlet pipe, so that they can only slide and cannot rotate, thereby preventing the first through hole and the second through hole from being misaligned in the circumferential direction, which would cause the first through hole and the second through hole to become out of concentricity after the water outlet pipe slides.

[0028] 3. In this application, a baffle is provided at the end of the slide rod away from the mounting ring. When the water outlet pipe and the mounting ring move, the slide rod moves. When the baffle contacts the stop block, the water outlet pipe cannot continue to slide outward, thus limiting the sliding distance of the water outlet pipe and ensuring that the second through hole and the first through hole can be concentric.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] like Figure 1-4As shown in the embodiment of this application, a water-saving micro-irrigation device for greening maintenance is disclosed, including an installation pipe 10, an installation plate 13, an installation ring 32, and a compression spring 35. A connecting plate 11 is provided at one end of the installation pipe 10, and a connection port 12 is provided on the connecting plate 11. The connection port 12 is connected to an external water source, which can be a tap water pipe and its internal water flow, or water pumped out by a water pump outlet pipe 30. The installation plate 13 is located on the side of the installation pipe 10 away from the connecting plate 11. A through hole 14 is provided in the middle of the installation plate 13. A protective pipe 20 is provided at the sliding hole 41 on the installation plate 13, and the end of the protective pipe 20 away from the installation pipe 10 is closed. The diameter of the through hole 14 is the same as the inner diameter of the protective pipe 20. A plurality of first through holes 21 are spaced apart on the protective pipe 20. A water outlet pipe 30 is slidably disposed inside the protective pipe 20, and the end of the water outlet pipe 30 away from the installation pipe 10 is closed. A second through hole 31 is spaced apart on the outlet pipe 30. An installation ring 32 is positioned at one end of the outlet pipe 30 inside the installation pipe 10. The installation ring 32, installation pipe 10, protective pipe 20, and outlet pipe 30 are all concentric. An annular groove 33 is formed on the outer wall of the installation ring 32, and a rubber sealing ring 34 is installed within the annular groove 33. The rubber sealing ring 34 abuts against the inner wall of the installation pipe 10. A compression spring 35 is fitted onto the outlet pipe 30 between the installation plate 13 and the installation ring 32. One end of the compression spring 35 is connected to the installation plate 13, and the other end is connected to the installation ring 32. In the initial state, the compression spring 35 pushes the installation ring 32 and the outlet pipe 30 through its elastic force, causing the second through hole 31 and the first through hole 21 to separate. At this time, the protective pipe 20 blocks the second through hole 31, preventing sediment from entering the outlet pipe 30 through the second through hole 31 or remaining in the second through hole 31, thus affecting the water output effect of the second through hole 31. During irrigation, an external water source is activated, and water enters the installation pipe 10 through the connection port 12. Under water pressure, the installation ring 32 and the outlet pipe 30 are pushed and moved, causing the second through hole 31 and the first through hole 21 to become concentric, allowing water to flow out through the second through hole 31 and the first through hole 21 to irrigate the surrounding greenery. When the installation ring 32 moves, the compression spring 35 is compressed. When the external water source is turned off, the compression spring 35 loses its restraint and pushes the installation ring 32 and the outlet pipe 30 back to their original positions under the action of elasticity, and the first through hole 21 and the second through hole 31 are misaligned. The protection of the second through hole 31 is achieved by automatically opening and closing according to the external water source, reducing the need for manual operation and making it more convenient. Moreover, water can only flow out through the second through hole 31 and the first through hole 21, resulting in less water consumption and saving water resources.

[0036] Specifically, two stops 40 are spaced apart circumferentially inside the installation pipe 10. In the initial state, the stops 40 are in contact with the installation ring 32, restricting the position of the installation ring 32. A sliding hole 41 is provided on the stops 40, and the length direction of the sliding hole 41 is consistent with the length direction of the water outlet pipe 30. A sliding rod 42 is slidably arranged in the sliding hole 41. The sliding rod 42 is connected to the side of the installation ring 32 away from the water outlet pipe 30. The sliding rod 42 restricts the installation ring 32 and the water outlet pipe 30, so that they can only slide and cannot rotate, to prevent the first through hole 21 and the second through hole 31 from being misaligned in the circumferential direction, which would cause the first through hole 21 and the second through hole 31 to become out of concentricity after the water outlet pipe 30 slides. A baffle plate 43 is provided at the end of the slide rod 42 away from the mounting ring 32. When the water outlet pipe 30 and the mounting ring 32 move, the slide rod 42 moves. When the baffle plate 43 contacts the stop block 40, the water outlet pipe 30 cannot continue to slide outward, thus limiting the sliding distance of the water outlet pipe 30 and ensuring that the second through hole 31 and the first through hole 21 can be concentric.

[0037] During setup, the distance between two adjacent first through holes 21 is consistent with the distance between two adjacent second through holes 31, ensuring that each first through hole 21 and its corresponding second through hole 31 are concentric after the water outlet pipe 30 is moved. The diameter of the first through hole 21 is larger than the diameter of the second through hole 31. The larger diameter of the first through hole 21 prevents sand and gravel from clogging it. The thin wall of the protective pipe 20 results in a shorter hole depth for the first through hole 21, further preventing sand and gravel clogging. Furthermore, due to the shorter hole depth and larger diameter of the first through hole 21, sand and gravel are difficult to get stuck inside, and when water exits from the second through hole 31, they can be easily flushed away.

[0038] In the specific configuration, a first mounting groove 22 is formed on the inner wall of the protective pipe 20 corresponding to the first through hole 21. A first rubber ring 23 is installed in the first mounting groove 22, and the first rubber ring 23 abuts against the outer wall of the outlet pipe 30, so that when external sand and gravel are in the first through hole 21, they cannot enter the gap between the protective pipe 20 and the outlet pipe 30. A second mounting groove 36 is formed on the outer wall of the outlet pipe 30 corresponding to the second through hole 31. A second rubber ring 37 is installed in the second mounting groove 36, and the second rubber ring 37 abuts against the inner wall of the protective pipe 20, preventing water from flowing into the gap between the protective pipe 20 and the outlet pipe 30.

[0039] The bottom of the mounting tube 10 is provided with a base 15, and the bottom of the base 15 is provided with four ground nails 16. The four ground nails 16 are arranged in a rectangular array and are driven into the soil to fix the position of the base 15 and the mounting tube 10.

[0040] The operating principle of the water-saving micro-irrigation device for greening maintenance in this embodiment is as follows: During irrigation, an external water source is activated, and the external water source enters the installation pipe 10 through the connection port 12. Under water pressure, the installation ring 32 and the outlet pipe 30 are pushed to move. The sliding hole 41 and the sliding rod 42 restrict the installation ring 32 and the outlet pipe 30 to slide until the baffle 43 contacts the stop block 40, and the outlet pipe 30 is restricted. At this time, the second through hole 31 and the first through hole 21 are concentric, and the water flow can be rushed out through the second through hole 31 and the first through hole 21 to irrigate the surrounding greenery. When the installation ring 32 moves, the compression spring 35 is compressed. When the external water source is turned off, the compression spring 35 loses its restriction and pushes the installation ring 32 and the outlet pipe 30 to reset under the action of elasticity. The first through hole 21 and the second through hole 31 are misaligned, and the protective pipe 20 blocks the second through hole 31. The protection of the second through hole 31 is automatically opened and closed according to the external water source, reducing the operation of staff and making it more convenient.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
