Description

Technical Field

[0001] The invention belongs to the technical field of gardening and municipal engineering, and in particular relates to a gardening and greening water supply device. Background Art

[0002] In order to beautify the environment and improve air quality, the green plant coverage area in cities is gradually increasing. Among them, laying lawns is a common greening method in cities. In addition to beautifying the environment and purifying the air, lawns can also be used as a place for residents to play, and are greening facilities with strong application effects.

[0003] In order to ensure that residents have a good platform for activities, staff are required to regularly maintain the lawn to ensure that the grass grows well. Watering and irrigation is a basic practice in daily lawn maintenance. Currently, there are three main ways of watering and irrigation: One is that the staff uses a handheld hose nozzle to water the lawn. This method requires a lot of labor for the staff, and often causes uneven watering, resulting in different degrees of lush growth in different parts of the grass; the second is to install multiple range sprinkler nozzles on the lawn, and the staff only needs to turn on the corresponding controller to use the nozzle for automatic sprinkler irrigation. This method requires less labor for the staff than the first manual method, but has the disadvantage of poor uniformity, and the working radius of a nozzle is fixed; the third is to use drip irrigation, which requires the installation of drip tubes over a large area and is more expensive.

[0004] Therefore, the above problems need to be solved urgently. Summary of the invention

[0005] Purpose of the invention: In order to overcome the above shortcomings, the present invention provides a landscaping water supply device with a simple structure and reasonable design. The spray pipe can be moved up and down and adjusted with the water flow, the spray head can rotate with the water flow, and the angle of the nozzle can be adjusted, so that the spraying range is larger and the spraying is more uniform.

[0006] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides a gardening water supply device, including a water supply pipe, a connecting pipe, a lifting pipe, a lifting device, a spray pipe and a nozzle, wherein the connecting pipe is connected to the water supply pipe, the lifting pipe and the lifting device are arranged inside the connecting pipe, the lifting device is arranged at the bottom of the connecting pipe, one end of the lifting pipe is connected to the lifting device, and the other end is connected to the spray pipe, and the other end of the spray pipe is equipped with a nozzle; The spray head comprises a connecting sleeve, a rotating sleeve, an angle adjusting member and a nozzle. The bottom of the connecting sleeve is connected to the spray pipe, and the upper part is rotatably connected to the rotating sleeve. The angle adjusting member is arranged on both sides of the rotating sleeve, and the nozzle is arranged at the end of the angle adjusting member.

[0007] The lifting device can move the spray pipe up and down to change the spray radius of the water flow. The rotating sleeve on the nozzle can rotate around the connecting sleeve to increase the centrifugal force of the water flow, expand the spray radius and spray more evenly. The angle of the nozzle can be adjusted by the angle adjustment part, further expanding the working range of the nozzle.

[0008] Furthermore, the connecting sleeve is embedded in the rotating sleeve and connected through a shaft sleeve. A rotating shaft is provided in the center of the rotating sleeve, and blades are spirally provided on the rotating shaft. When water flows into the rotating sleeve from the connecting sleeve, the water flows on the spiral blades to rotate the rotating shaft, thereby rotating the rotating sleeve and the angle adjustment member, without the need to install an external power device.

[0009] The angle adjustment member includes an oblique tube and an adjustment tube. One end of the oblique tube is connected to the rotating sleeve, and the other end is movably connected to the adjustment tube. A nozzle is arranged at the end of the adjustment tube. The adjustment tube also includes a hose. The hose is connected to the inner cavity of the rotating sleeve. The other end of the hose passes through the oblique tube and the adjustment tube and is connected to the nozzle. After the water flows through the spiral blades and rises to the top of the connecting sleeve, it enters the hoses on both sides and finally sprays out through the nozzle. Manually moving the adjustment tube can adjust its relative angle with the oblique tube to adjust the angle of the nozzle.

[0010] Furthermore, the lifting device includes a screw rod, a screw sleeve, and a bearing. The bottom of the screw rod is arranged on the bearing. The bearing is arranged on the bottom of the connecting pipe through a mounting block. The screw sleeve is arranged at the bottom of the lifting pipe and connected to the upper part of the screw rod. The screw rod is provided with a water wheel blade. After the water flows into the connecting pipe, it flushes the water wheel blade and drives the screw rod to rotate around the bearing. The screw sleeve moves up and down under the action of the screw rod, thereby driving the lifting pipe and the spray pipe on the upper part thereof to move up and down.

[0011] Furthermore, water inlets are symmetrically arranged on the side of the lifting pipe, and electromagnetic valves are arranged at the water inlets. Water flows into the cavity between the connecting pipe and the lifting pipe, and enters the interior of the lifting pipe through the water inlet. The on-off of the electromagnetic valves on both sides is controlled to control the water inlet on the left or right side, and the water flow speed on both sides is changed to change the rotation direction of the water wheel blades, so that the lifting pipe can reciprocate.

[0012] Furthermore, a first sealing ring is sleeved at the bottom of the spray pipe, and the first sealing ring is located in the connecting pipe and contacts the top of the connecting sleeve. A through hole for the spray pipe to pass through is opened at the top of the connecting pipe, and a second sealing ring is arranged in the through hole. The first sealing ring and the second sealing ring ensure the sealing performance and ensure that there is enough water pressure to drive the water wheel blades.

[0013] Furthermore, an internal thread is provided at the bottom of the connecting sleeve, the connecting sleeve is connected to the spray pipe via the internal thread, and a third sealing ring is embedded on the internal thread. The third sealing ring enhances the sealing between the spray pipe and the connecting sleeve, prevents water leakage between the connecting sleeve and the spray pipe, and also prevents the water pressure from decreasing and causing the rotating sleeve to be unable to rotate.

[0014] Furthermore, a connection block is provided on the adjusting pipe, a threaded hole is provided on the inclined pipe, and the inclined pipe and the adjusting pipe are connected by bolts passing through the connection block and the threaded hole. After loosening the bolts, the staff can rotate the adjusting pipe to a suitable angle and then tighten the bolts to achieve the angle adjustment of the nozzle.

[0015] It can be seen from the above technical solution that the present invention has the following beneficial effects: 1. The present invention provides a gardening water supply device, which has a simple structure. Water flows through a water supply pipe and enters a connecting pipe. Under the action of the water flow, the water wheel blades rotate, and a screw rod coaxially arranged therewith starts to rotate around a bearing. The rotation of the screw rod acts on a screw sleeve, causing the screw sleeve to start to move linearly up and down, thereby causing a lifting pipe and a spray pipe and a mechanism above the lifting pipe to move linearly up and down, changing the spray height of the water flow and thereby increasing its working radius.

[0016] 2. In the present invention, after the water flows into the nozzle, the blades rotate under the action of the water flow and drive the rotating shaft to rotate. The rotating shaft drives the rotating sleeve to rotate around the connecting sleeve, and the angle adjustment member and the nozzle on the upper part rotate synchronously, so that the spraying is more uniform and the range is larger. At the same time, the angle of the nozzle can be adjusted by the adjusting tube, which further broadens the working range of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] like Figure 1 As shown, a gardening water supply device comprises a water supply pipe 1, a connecting pipe 2, a lifting pipe 3, a lifting device 4, a spray pipe 5 and a nozzle 6, wherein the connecting pipe 2 is connected to the water supply pipe 1, the lifting pipe 3 and the lifting device 4 are arranged inside the connecting pipe 2, the lifting device 4 is arranged at the bottom of the connecting pipe 2, one end of the lifting pipe 3 is connected to the lifting device 4, and the other end is connected to the spray pipe 5, and the other end of the spray pipe 5 is installed with a nozzle 6; like Figure 2 As shown, the spray head 6 includes a connecting sleeve 61, a rotating sleeve 62, an angle adjustment member 63 and a nozzle 64. The bottom of the connecting sleeve 61 is connected to the spray pipe 5, and the upper part is rotatably connected to the rotating sleeve 62. The angle adjustment member 63 is arranged on both sides of the rotating sleeve 62, and the nozzle 64 is arranged at the end of the angle adjustment member 63.

[0021] The connecting sleeve 61 is embedded in the rotating sleeve 62 and connected via a shaft sleeve. A rotating shaft 621 is disposed in the center of the rotating sleeve 62, and blades 622 are spirally disposed on the rotating shaft 621. The angle adjustment member 63 includes an oblique tube 631 and an adjustment tube 632. One end of the oblique tube 631 is connected to the rotating sleeve 62, and the other end is movably connected to the adjustment tube 632. The end of the adjustment tube 632 is provided with a nozzle 64, and also includes a hose 633. The hose 633 is communicated with the inner cavity of the rotating sleeve 62, and the other end of the hose 633 passes through the oblique tube 631 and the adjustment tube 632 and is connected to the nozzle 64. The nozzle 64 and the adjustment tube 632 can be connected by threads, and the nozzle 64 can be selected from atomizing nozzles, straight nozzles, etc. according to the usage scenario.

[0022] like Figure 1 As shown, the lifting device 4 includes a screw rod 41, a threaded sleeve 42, and a bearing 43. The bottom of the screw rod 41 is arranged on the bearing 43, and the bearing 43 is arranged at the bottom of the connecting pipe 2 through a mounting block. The threaded sleeve 42 is arranged at the bottom of the lifting pipe 3 and connected to the upper part of the screw rod 41. The screw rod 41 is provided with a water wheel blade 44.

[0023] In a further optimized solution, water inlets are symmetrically arranged on the side of the lifting pipe 3, and a solenoid valve 31 is arranged at the water inlet. If the solenoid valve 31 on the right is closed, water flows into the lifting pipe 3 from the water inlet on the left, and the water flow speed on the left side between the lifting pipe 3 and the connecting pipe 2 is much greater than that on the right side. At this time, the water flow mainly flushes the left side of the water wheel blade 44 to make it rotate counterclockwise, and the screw sleeve 42 rises, that is, the spray pipe 5 rises, and vice versa, the spray pipe 5 can be lowered. At the same time, the switching frequency of the solenoid valves 31 on the left and right sides can be set to control the frequency of the spray pipe 5 moving up and down.

[0024] Please refer again Figure 1 A first sealing ring 51 is sleeved on the bottom of the spray pipe 5 , and the first sealing ring 51 is located in the connecting pipe 2 and contacts the top of the connecting sleeve 2 .

[0025] In addition, a through hole is provided at the top of the connecting pipe 2 for the spray pipe 5 to pass through, and a second sealing ring 21 is provided in the through hole. In order to prevent the spray pipe 5 from moving unsmoothly, a sleeve can be installed in the through hole and sealed, and the stress of the spray pipe 5 rotating slightly following the screw sleeve 42 can be released, thereby improving the service life.

[0026] like Figure 2 As shown, an internal thread 611 is provided at the bottom of the connecting sleeve 61 , and the connecting sleeve 61 is connected to the spray pipe 5 via the internal thread 611 . A third sealing ring 612 is embedded on the internal thread 611 .

[0027] like Figure 3 As shown, a connection block is provided on the adjusting tube 632 , and a threaded hole is provided on the inclined tube 631 . The inclined tube 631 and the adjusting tube 632 are connected by bolts passing through the connection block and the threaded hole.

[0028] The present invention provides a gardening water supply device, which has the following working principle: water flows through a water supply pipe 1 and enters a connecting pipe 2. Under the action of the water flow, a water wheel blade 44 rotates, and a screw rod 41 coaxially arranged therewith starts to rotate around a bearing 43. The screw rod 41 rotates and acts on a screw sleeve 42, causing the screw sleeve 42 to start to move linearly up and down, thereby causing a lifting pipe 3 and a spray pipe 5 and a mechanism on the upper part thereof to move linearly up and down, changing the spray height of the water flow and thereby increasing its working radius. Water flows through the spray pipe 5 and enters a connecting sleeve 61 and a rotating sleeve 62. Under the action of the water flow, a blade 622 rotates and drives a rotating shaft 621 to rotate. The rotating shaft 621 drives the rotating sleeve 62 to rotate around the connecting sleeve 61, and an angle adjustment member 63 and a nozzle 64 on the upper part thereof rotate synchronously, so that the spraying is more uniform and has a larger range. Finally, the water flows through the upper part of the rotating sleeve 62 and enters a hose 633, and is finally sprayed out by the nozzle 64.

[0029] In summary, the landscaping water supply device provided by the present invention improves the problem of uneven watering, broadens the coverage range of a single machine, and saves costs.
