Description

Technical Field

[0001] This invention belongs to the field of landscaping irrigation, specifically a water-saving irrigation device for landscaping projects. Background Technology

[0002] Garden irrigation is a technical measure to replenish the soil moisture needed for the growth of garden plants, thereby improving their growing conditions. It utilizes manual or mechanical methods in various forms of irrigation to replenish the soil moisture in garden green spaces and meet the water requirements of the plants.

[0003] Chinese invention patent CN113678713B discloses a water-saving sprinkler irrigation device for landscaping projects, including a sprinkler head and a connecting device. The connecting device is installed at the input end of the sprinkler head to connect it to a water pipe. When the sprinkler head is working, the connecting device adjusts the height of the sprinkler head according to the ground level. In this water-saving sprinkler irrigation device, when the sprinkler head is working, a drive mechanism causes a rotating pipe to move upward within the connecting pipe, thereby raising the sprinkler head. The drive mechanism adjusts the height of the sprinkler head according to the opening degree of a baffle, which is related to the ground level, thus automatically adjusting the sprinkler head height based on the ground level.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: existing irrigation devices typically have a single height adjustment function, but do not have the function of automatically adjusting the nozzle flow rate according to the ambient temperature; and the spraying range of the nozzle is limited by the pipe length.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a water-saving irrigation device for landscaping projects. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a water-saving irrigation device for landscaping projects, which solves the problems that existing irrigation devices typically have only a single height adjustment function but do not have the function of automatically adjusting the nozzle flow rate according to the ambient temperature; and the spraying range of the nozzle is limited by the pipe length.

[0007] A water-saving irrigation device for landscaping projects includes a buried pipe with several flexible hoses arranged in a circular array at its port. A conduit is installed at one end of each flexible hose, and several fixing brackets are also provided at the port of the buried pipe. The conduit is hinged to the fixing brackets, and an extension pipe is slidably connected inside the conduit. An atomizing pipe is installed at one end of the extension pipe, and a flow regulating component is installed on the inner wall of the atomizing pipe. An angle regulating component is installed on the periphery of the conduit. The flow regulating component includes a regulating pipe installed on the inner wall of the atomizing pipe, a regulating groove formed on the inner wall of the atomizing pipe, a push ring fixed to the periphery of the regulating pipe and sliding within the regulating groove, a water guide groove formed on the periphery of the regulating pipe port, a heat-conducting layer disposed on the outer walls of the extension pipe and the atomizing pipe, and a memory metal rod connecting the regulating groove and the push ring.

[0008] By adopting the above scheme, external water is introduced into the buried pipe through the pump body, then into the conduit through the flexible hose, and sprayed out through the extension pipe and the atomizing pipe. By setting an angle adjustment component, the angle of multiple sets of conduits can be adjusted simultaneously to change the irrigation range and increase the irrigation area. The flow adjustment component senses the ambient temperature, and the temperature is transmitted to the memory metal rod, causing the position of the adjustment pipe to change, which in turn changes the opening of the water channel, thereby changing the irrigation water flow. In cold and humid weather, the memory metal rod is shortened, reducing the water flow in the adjustment pipe, thus reducing the irrigation water flow and ensuring stable irrigation for greening while saving water resources. In hot weather, the rate of water evaporation from greening is accelerated, leading to greater water shortage. The memory metal rod elongates when heated, increasing the water flow in the adjustment pipe, increasing the irrigation volume, and preventing water shortage for greening plants in high-temperature environments.

[0009] Preferably, a water outlet is provided at the port of the atomizing tube, the water guide groove is connected to the water outlet, and an atomizing head is installed at one end of the atomizing tube.

[0010] Preferably, the angle adjustment component includes a sealing frame installed on the inner wall of the buried pipe, a micro motor installed in the sealing frame, a support frame fixed to the surface of the buried pipe and located at a symmetrical position to the center of multiple sets of conduits, a lead screw installed at the output end of the micro motor and located in the support frame, a slider threaded to the periphery of the lead screw, and a connecting rod connecting the side wall of the slider and the conduit.

[0011] Preferably, the inner wall of the support frame is provided with a lifting groove, the slider slides in the lifting groove, each side wall of the slider is connected to a first connecting frame, the position of the first connecting frame is adapted to the guide tube, the periphery of the guide tube is rigidly connected to a second connecting frame, and a hinged connecting rod is connected between the first connecting frame and the second connecting frame.

[0012] Preferably, the peripheral side of the catheter is further equipped with an extension assembly for adjusting the length of the extension tube. The extension assembly includes an electric push rod installed on the peripheral side of the catheter and a connecting plate connected to the telescopic end of the electric push rod and the peripheral side of the extension tube.

[0013] By adopting the above solution, the irrigation range can be further changed by extending the component to change the extension pipe's telescopic distance, making it easier to irrigate green plants over a larger area.

[0014] Preferably, one end of the support frame is fixedly connected to a limiting ring, and the limiting ring has several connecting grooves on its circumferential side, with the position of the extension tube matching the connecting grooves.

[0015] Preferably, a support rod is fixedly connected to the side of the limiting ring, and an atomizing impact plate is installed at one end of the support rod, with the atomizing impact plate located above the limiting ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention senses the ambient temperature through a flow regulation component. The temperature is transmitted to the memory metal rod, causing a change in the position of the regulating pipe and thus altering the opening of the water channel, thereby changing the irrigation water flow rate. In cold and humid weather, the memory metal rod shortens, reducing the water flow rate in the regulating pipe and thus reducing the irrigation water flow, ensuring stable irrigation for greenery while saving water resources. In hot weather, the rate of water evaporation from greenery increases, leading to greater water shortage. The memory metal rod elongates when heated, increasing the water flow rate in the regulating pipe and improving irrigation output, preventing water shortage in greenery under high temperatures. This device allows for rapid adaptation to ambient temperature, consistently using a water flow rate appropriate to the ambient temperature during irrigation, thereby achieving water-saving irrigation.

[0018] 2. This invention can simultaneously adjust the angles of multiple sets of conduits through the angle adjustment component, thereby changing the irrigation range and increasing the irrigation area; through the flow adjustment component, the ambient temperature is sensed and the temperature is conducted to the memory metal rod, causing the position of the adjustment pipe to change, which in turn changes the opening degree of the water channel, thereby changing the irrigation water flow rate.

[0019] 3. This invention changes the extension distance of the extension tube by extending the component, thereby changing the irrigation range and facilitating flexible irrigation of green plants over a larger area. Attached Figure Description

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] Example 1: As shown in the attached document Figure 1 To be continued Figure 7 As shown: This invention provides a water-saving irrigation device for landscaping projects, including a buried pipe 1. Several flexible hoses 2 are connected to the ends of the buried pipe 1 in a circular array. A conduit 3 is installed at one end of each flexible hose 2. Several fixing brackets 4 are also provided at the ends of the buried pipe 1. The conduit 3 is hinged to the fixing brackets 4. An extension pipe 5 is slidably connected inside the conduit 3. An atomizing pipe 16 is installed at one end of the extension pipe 5. A flow regulating component is installed on the inner wall of the atomizing pipe 16. An angle regulating component is installed on the periphery of the conduit 3.

[0031] The flow regulation assembly includes a regulating tube 18 installed on the inner wall of the atomizing tube 16, a regulating groove 17 opened on the inner wall of the atomizing tube 16, a push ring 19 fixed to the periphery of the regulating tube 18 and sliding in the regulating groove 17, a water guide groove 23 opened on the periphery of the port of the regulating tube 18, a heat-conducting layer 21 provided on the outer wall of the extension tube 5 and the atomizing tube 16, and a memory metal rod 20 connecting the regulating groove 17 and the push ring 19.

[0032] A water outlet 22 is provided at the end of the atomizing tube 16, and a water guide groove 23 is connected to the water outlet 22. An atomizing head 24 is installed at one end of the atomizing tube 16. An angle adjustment component is installed on the inner wall of the buried pipe 1, including a sealing frame 12, a micro motor 13 installed in the sealing frame 12, a support frame 11 fixed to the surface of the buried pipe 1 and located at the center symmetrical position of multiple sets of conduits 3, a lead screw 14 installed at the output end of the micro motor 13 and located in the support frame 11, a slider 15 threaded on the periphery of the lead screw 14, and a connecting rod 27 connecting the side wall of the slider 15 and the conduit 3. A lifting groove 1101 is opened on the inner wall of the support frame 11, and the slider 15 slides in the lifting groove 1101. Each side wall of the slider 15 is connected to a first connecting frame 1501. The position of the first connecting frame 1501 is adapted to the conduit 3. A second connecting frame 301 is rigidly connected to the periphery of the conduit 3. The connecting rod 27 is hinged between the first connecting frame 1501 and the second connecting frame 301.

[0033] One end of the support frame 11 is fixedly connected to a limiting ring 10. Several connecting grooves 25 are opened on the side of the limiting ring 10. The position of the extension tube 5 is adapted to the connecting grooves 25. A support rod 8 is fixedly connected to the side of the limiting ring 10. An atomizing impact plate 9 is installed at one end of the support rod 8. The atomizing impact plate 9 is located above the limiting ring 10.

[0034] As shown above, external water is introduced into the buried pipe 1 through the pump body, then into the conduit 3 through the hose 2, and sprayed out through the extension pipe 5 and the atomizing pipe 16. The heat-conducting layer 21 of the extension pipe 5 and the atomizing pipe 16 can quickly absorb external heat, and the shape memory metal rod 20 can be stably heated. The shape memory metal rod 20 has a temperature sensing function and is supported by a nickel-titanium alloy. The shape memory metal rod 20 senses the ambient temperature through the heat-conducting layer 21. When heated, the shape memory metal rod 20 elongates, and the regulating pipe 18 is raised through the push ring 19. The cross-section of the opening of the water guide trough 23 and the outlet 22 is increased, thereby increasing the water flow rate. The water is then atomized by the atomizing head 24. In cold and humid weather, the shape memory metal rod 20 is shortened, and the water flow rate of the regulating pipe 18 is reduced, thereby reducing the irrigation water flow rate. This ensures stable irrigation for greening while saving water resources. By adopting the above method, the device can quickly adapt to the ambient temperature and always use a water flow rate that is suitable for the ambient temperature during irrigation, thereby achieving the function of water-saving irrigation.

[0035] The angle adjustment component allows for simultaneous adjustment of the angles of multiple sets of conduits 3. Controlling the micro motor 13 drives the lead screw 14 to rotate. The lead screw 14 engages with the slider 15 via a threaded connection, causing the slider 15 to rise and fall stably. The rise and fall of the slider 15, via the first connecting frame 1501, displaces the connecting rod 27. The connecting rod 27, in conjunction with the second connecting frame 301, changes the angle of the conduit 3, thus altering the irrigation range of the irrigation device. Figure 5It can be seen that the spraying angle of the conduit 3 changes after the angle is changed, thereby increasing the irrigation range; and the angle adjustment component is installed in conjunction with the conduit 3, making the overall structure of the device compact, with a volume roughly the same as that of conventional buried irrigation pipes; while keeping the volume unchanged, the irrigation efficiency and flexibility are greatly improved.

[0036] Example 2: As shown in the attached document Figure 1 To be continued Figure 7 As shown: This embodiment is basically the same as the previous embodiment, except that an extension component for adjusting the length of the extension tube 5 is also installed on the side of the conduit 3. The extension component includes an electric push rod 6 installed on the side of the conduit 3 and a connecting plate 7 connected to the telescopic end of the electric push rod 6 and the side of the extension tube 5.

[0037] As can be seen from the above, by controlling the operation of the electric push rod 6, the electric push rod 6 drives the extension pipe 5 to extend and retract through the connecting plate 7, thereby further changing the irrigation range.
