Description

Technical Field

[0001] This invention relates to the field of watering, and more specifically, to a sprinkler irrigation device for greening in construction projects. Background Technology

[0002] In the field of architectural engineering, in order to create a more comfortable and pleasant living environment and effectively improve indoor air quality, designers usually choose to cultivate a large number of green plants as a means of decoration and purification. Green plants can not only release oxygen and absorb carbon dioxide through photosynthesis, but also absorb harmful substances in the air, such as formaldehyde and benzene, thereby significantly improving indoor air quality.

[0003] However, cultivating green plants is not a one-time task; subsequent maintenance is equally crucial. Irrigation, as a key aspect of plant care, directly affects the growth and survival rate of plants. Therefore, choosing and using appropriate irrigation devices is essential for the maintenance of green plants.

[0004] The grass blades will gradually increase in length, and may even extend above the irrigation equipment. These grass blades may not have been removed or damaged when the equipment is extended to irrigate, so they may become an obstacle when the equipment tries to retract underground after irrigation.

[0005] Secondly, some grass blades may become loose due to wind or contact, and fall onto the movement path of the irrigation equipment as it retracts, creating a physical obstacle. These fallen grass blades may get stuck in the sliding parts or mechanical structure of the equipment, increasing friction and affecting the smooth retraction of the equipment.

[0006] Longer grass blades may deform due to compression or entanglement during equipment retraction, further complicating the process. Frequent occurrences of this can lead to increased wear on mechanical components over time, potentially causing malfunctions and affecting the long-term stability and automatic lifting function of the irrigation equipment. Therefore, we propose a sprinkler irrigation device for greening in construction projects. Summary of the Invention

[0007] This invention provides a sprinkler irrigation device for greening in building engineering, which solves the technical problems in related technologies.

[0008] This invention provides a sprinkler irrigation device for greening in construction projects, including: a level plate and a sprinkler head, the design height of which is level with the ground of the green lawn. The sprinkler head is set at the center of the level plate and is used to provide irrigation water to the green lawn. The sprinkler head is also integrated into the level plate and has a leaf removal mechanism, which is used to automatically remove the green lawn leaves covering the level plate before the sprinkler head performs irrigation operations.

[0009] The leaf-cleaning mechanism includes two symmetrically arranged leaf-cutting arms for performing the cutting action;

[0010] The drive assembly includes a lifting main pipe and a power receiving cylinder linked thereto. The lifting main pipe rises in response to the water pressure generated by the irrigation water supply system and drives the power receiving cylinder to rotate through a mechanical connection with the flat plate.

[0011] The leaf-flush assembly includes multiple flush nozzles evenly distributed along the outer wall of the lifting main pipe. After irrigation, the residual irrigation water inside the lifting main pipe is sprayed out through the flush nozzles as it descends, directly impacting the surface of the cutting plate and removing the lawn blades broken by the leaf-cutting arm.

[0012] Furthermore, a sprinkler irrigation pipe is fixedly installed below the flat plate, and a water supply network is fixedly connected below the sprinkler irrigation pipe. The water supply network and the sprinkler irrigation pipe are internally interconnected. A water supply branch pipe is fixedly installed on one side of the sprinkler irrigation pipe in the direction of water flow of the water supply network. Both ends of the water supply branch pipe are interconnected with the sprinkler irrigation pipe and the water supply network, respectively.

[0013] Furthermore, the lifting main pipe is slidably connected to the sprinkler irrigation buried pipe, and an inner pipe is provided on the inner side of the lifting main pipe that is fixedly connected to the sprinkler irrigation buried pipe. The inner pipe is connected to the water supply network. The sprinkler head is located in the inner pipe and is slidably connected to the inner pipe. Moreover, the water flowing into the sprinkler irrigation buried pipe from the water supply branch pipe is collected in the space between the outer wall of the inner pipe and the inner wall of the sprinkler irrigation buried pipe. The water flowing into the sprinkler irrigation buried pipe from the water supply network is collected in the inner pipe.

[0014] Furthermore, the drive assembly also includes a threaded groove formed on the outer wall of the lifting main tube, a convex ball fixedly provided on the inner wall of the force collection cylinder, and the convex ball and the threaded groove matching each other, a power storage coil spring fixedly provided on the outer wall of the force collection cylinder, a power release ring fixedly provided on the outer end of the power storage coil spring, and extension columns fixedly provided on both sides of the power release ring, with the extension columns rotatably connected to the blade cutting arm.

[0015] Furthermore, a transmission arm is inserted inside the extension column, and the transmission arm is L-shaped. The transmission arm is rotatably connected to the extension column and fixedly connected to the blade-cutting arm. The rotation of the transmission arm drives the blade-cutting arm to rotate, and the rotation angle range of the blade-cutting arm is 0-90°.

[0016] Furthermore, a liquid storage box is fixedly connected to the force release ring below the transmission arm. A power supply box is provided between the liquid storage box and the transmission arm, and the power supply box is fixedly connected to the liquid storage box. At the same time, the two are interconnected. A lifting box is provided at one end of the power supply box, and a tightening belt is fixedly provided in the side gap of the lifting box. The expansion of the power supply box is fan-shaped.

[0017] Furthermore, a blocking head is provided above the transmission arm, which passes through the force release ring. The lower wall of the blocking head is fixedly provided with a control line and a push spring, and several control lines are provided. The end of the control lines away from the blocking head is fixedly connected to the bottom wall of the liquid storage box. The blocking head and the force release ring form a telescopic structure.

[0018] Furthermore, a locking groove is provided in the flat plate corresponding to the position of the blocking head. A push column is provided inside the locking groove. A pull rope is fixedly provided on one side of the push column. The push column and the locking groove form a telescopic structure. A control head is provided at the end of the pull rope away from the push column.

[0019] Furthermore, the lower wall of the lifting main pipe is fixedly equipped with a drain outlet and a reset cable. The end of the reset cable away from the lower wall of the lifting main pipe is fixedly connected to the inner bottom wall of the sprinkler pipe. Multiple flushing outlets and drain outlets are interconnected.

[0020] Furthermore, the channel between the drain outlet and the flush outlet is a waterway, in which a blocking bladder is fixedly installed. The air inlet of the blocking bladder is connected to an airbag through a pipe, and the airbag is fixedly connected to the lifting main pipe.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention achieves automated leaf removal before irrigation by integrating a leaf-cleaning mechanism. The leaf-cutting arm design in the mechanism can precisely cut the leaves of the lawn covering the sprinkler plate, effectively preventing the leaves from obstructing the sprinkler effect. At the same time, the drive component uses the water pressure generated by the irrigation water supply system to drive the lifting main pipe to rise, and drives the return cylinder to rotate through a mechanical connection, providing a stable and reliable power source for the leaf-cutting arm.

[0023] The blade-flush assembly is ingeniously designed, making full use of the irrigation water remaining inside the main lifting pipe as it descends. This water is then sprayed out through evenly distributed nozzles, directly impacting the flushing surface and effectively removing grass blades broken by the blade-cutter arms. This design not only prevents grass blades from affecting the retraction of the sprinkler head after irrigation but also prevents grass blades from entering the device, ensuring its normal operation.

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a building construction greening sprinkler irrigation device includes: a flush plate 14 and a sprinkler head 16, the design height of which is flush with the ground of the green lawn. The sprinkler head 16 is set at the center of the flush plate 14 and is used to provide irrigation water to the green lawn. The sprinkler head 16 is integrated into the flush plate 14 and is used to automatically remove the green lawn leaves covering the flush plate 14 before the sprinkler head 16 performs irrigation operations.

[0036] The leaf-cleaning mechanism 2 includes two symmetrically arranged leaf-cutting arms 21 for performing cutting actions;

[0037] The drive assembly includes a lifting main pipe 15 and a power receiving cylinder 24 linked thereto. The lifting main pipe 15 rises in response to the water pressure generated by the irrigation water supply system and drives the power receiving cylinder 24 to rotate through a mechanical connection with the flat plate 14.

[0038] The leaf-flushing assembly includes multiple flushing nozzles 43 evenly distributed along the outer wall of the lifting main pipe 15. After irrigation, the irrigation water remaining inside the lifting main pipe 15 is sprayed out through the flushing nozzles 43 when it descends, directly impacting the surface of the flushing plate 14 to remove the lawn leaves broken by the leaf-cutting arm 21.

[0039] A sprinkler irrigation pipe 11 is fixedly installed below the flat plate 14. A water supply network 12 is fixedly connected below the sprinkler irrigation pipe 11. The water supply network 12 and the sprinkler irrigation pipe 11 are internally interconnected. A water supply branch pipe 13 is fixedly installed on one side of the sprinkler irrigation pipe 11 in the direction of water flow of the water supply network 12. The two ends of the water supply branch pipe 13 are respectively connected to the sprinkler irrigation pipe 11 and the water supply network 12.

[0040] The lifting main pipe 15 is slidably connected to the sprinkler irrigation buried pipe 11. An inner pipe 18 is provided on the inner side of the lifting main pipe 15 and is fixedly connected to the sprinkler irrigation buried pipe 11. The inner pipe 18 is connected to the water supply network 12. The sprinkler irrigation head 16 is located in the inner pipe 18 and is slidably connected to the inner pipe 18. Water flowing into the sprinkler irrigation buried pipe 11 from the water supply branch pipe 13 is collected in the space between the outer wall of the inner pipe 18 and the inner wall of the sprinkler irrigation buried pipe 11. Water flowing into the sprinkler irrigation buried pipe 11 from the water supply network 12 is collected in the inner pipe 18.

[0041] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the drive assembly also includes a threaded groove 17 formed on the outer wall of the lifting main tube 15, a convex ball 25 fixedly provided on the inner wall of the force-collecting cylinder 24, and the convex ball 25 and the threaded groove 17 are matched with each other, a power-accumulating coil spring 23 fixedly provided on the outer wall of the force-collecting cylinder 24, a power-releasing ring 26 fixedly provided on the outer end of the power-accumulating coil spring 23, and an extension column 22 fixedly provided on both sides of the power-releasing ring 26, and the extension column 22 is rotatably connected to the blade-cutting arm 21.

[0042] The extension column 22 is equipped with a transmission arm 27, which is L-shaped. The transmission arm 27 is rotatably connected to the extension column 22 and fixedly connected to the blade-cutting arm 21. The rotation of the transmission arm 27 drives the blade-cutting arm 21 to rotate, and the rotation angle of the blade-cutting arm 21 is 0-90°.

[0043] Below the transmission arm 27 is a liquid storage box 32 that is fixedly connected to the force release ring 26. A power supply box 34 is provided between the liquid storage box 32 and the transmission arm 27, and the power supply box 34 is fixedly connected to the liquid storage box 32 and the two are interconnected. A lifting box 36 is provided at one end of the power supply box 34, and a tightening belt 37 is fixedly provided in the side gap of the lifting box 36. The expansion of the power supply box 34 is fan-shaped.

[0044] A blocking head 31 is provided above the transmission arm 27, which passes through the force release ring 26. A control line 33 and a push spring 35 are fixedly provided on the lower wall of the blocking head 31. Several control lines 33 are provided. The ends of the control lines 33 away from the blocking head 31 are fixedly connected to the bottom wall of the liquid storage box 32. The blocking head 31 and the force release ring 26 form a telescopic structure.

[0045] like Figure 9 As shown, a slot 302 is provided in the flat plate 14 at the position corresponding to the blocking head 31. A push post 301 is provided inside the slot 302. A pull rope 39 is fixedly provided on one side of the push post 301. The push post 301 and the slot 302 form a telescopic structure. A control head 38 is provided at the end of the pull rope 39 away from the push post 301.

[0046] The lower wall of the lifting main pipe 15 is fixedly provided with a drain outlet 41 and a reset pull line 44. The end of the reset pull line 44 away from the lower wall of the lifting main pipe 15 is fixedly connected to the inner bottom wall of the sprinkler pipe 11. Multiple flushing outlets 43 are interconnected with the drain outlet 41.

[0047] The channel between the drain outlet 41 and the flush outlet 43 is a waterway. A blocking bladder 42 is fixedly installed in the waterway. An air bladder 45 is installed at the air inlet end of the blocking bladder 42 through a pipe. The air bladder 45 is fixedly connected to the lifting main pipe 15.

[0048] The device is in standby mode. The flush plate 14 is flush with the green lawn. The sprinkler head 16 is hidden under the flush plate 14. The leaf-cutting arm 21 of the leaf-cleaning mechanism 2 is in a closed state. The energy storage spring 23 does not store potential energy. The lifting main pipe 15 is located inside the sprinkler buried pipe 11 and is slidably connected to the inner pipe 18. The blocking bladder 42 is in an uninflated state. The drain outlet 41 is blocked.

[0049] When the irrigation system is started, part of the water flows directly into the inner pipe 18 through the water supply network 12, and another part of the water flows through the water supply branch pipe 13 into the space between the outer wall of the inner pipe 18 and the inner wall of the sprinkler buried pipe 11, providing the water pressure required for the lifting main pipe 15 to rise.

[0050] The corresponding water pressure rises in the lifting main pipe 15, driving the upper blade cutting mechanism to move. The threaded groove 17 interacts with the convex ball 25, causing the force collection cylinder 24 to rotate as the lifting main pipe 15 rises. When the force collection cylinder 24 rotates, it gradually tightens the energy storage coil spring 23 to store potential energy until the limit plate at the bottom of the lifting main pipe 15 rises to the highest point, squeezing the control head 38. The control head 38 pulls the pull rope 39, which in turn pulls the push column 301 to extend and squeeze the blocking head 31, causing the blocking head 31 to retract back into the force release ring 26.

[0051] As the blocking head 31 retracts, it pulls multiple control lines 33, which in turn pull the bottom plate of the liquid storage box 32, squeezing the liquid storage box 32 and causing the liquid in the liquid storage box 32 to enter the power supply box 34. This causes the lifting box 36 to expand in a fan shape, pushing the L-shaped transmission arm 27 and causing the transmission arm 27 to rotate 90 degrees. The transmission arm 27 then drives the blade cutting arm 21 to rotate 90 degrees, thus unfolding the blade cutting arm 21.

[0052] The transmission arm 27 drives the leaf-cutting arm 21 to open from the closed state to 90 degrees. At this time, the force-releasing ring 26 loses resistance. Through the elasticity of the energy-storing coil spring 23, the force-releasing ring 26 is driven to rotate. The force-releasing ring 26 drives the extension column 22 to rotate. The extension column 22 drives the leaf-cutting arm 21 to rotate rapidly and cut the lawn blades covering the flat plate 14.

[0053] The sprinkler head 16 extends from the flush plate 14 to begin irrigating the lawn. After irrigation, the water pressure in the lifting pipe 15 drops, and the reset cable 44 pulls it down. The blocking bladder 42 contracts due to the air venting of the air bladder 45, allowing the drain outlet 41 to connect with the flush outlet 43. The remaining irrigation water is sprayed out from the flush outlet 43, impacting the flush plate 14 and removing broken lawn leaves.

[0054] After the lifting main pipe 15 has fully descended, the blade cutting arm 21 is reset to its initial state under the action of the energy storage spring 23, and the device returns to the standby state, waiting for the next irrigation command.

[0055] Standby state: When the device is in standby state, the flush plate 14 is flush with the green lawn surface, the sprinkler head 16 is hidden below the flush plate 14, and the leaf-cutting arm 21 of the leaf-cleaning mechanism 2 is in the closed state. The energy storage spring 23 does not store potential energy, the lifting main pipe 15 is located inside the sprinkler buried pipe 11, and is slidably connected to the inner pipe 18. The blocking bladder 42 is in the uninflated state, and the drain outlet 41 is blocked.

[0056] Keep the device low and concealed so as not to obstruct the appearance of the lawn, while ensuring that the leaf-clearing mechanism 2 will not be misoperated when in standby mode.

[0057] Irrigation system startup and lifting main pipe 15 rise: When the irrigation system is started, water enters the inner pipe 18 and the space between the sprinkler buried pipe 11 and the inner pipe 18 through the water supply network 12 and water supply branch pipe 13 respectively, providing the water pressure required for the lifting main pipe 15 to rise. The lifting main pipe 15 responds to the rise of water pressure and drives the leaf cleaning mechanism 2 on its upper part to move.

[0058] The lifting pipe 15 is driven to rise by the pressure of the irrigation water itself, requiring no additional power source, which is energy-saving and environmentally friendly.

[0059] Rotation of the power collection cylinder 24 and storage of potential energy: During the ascent of the lifting main tube 15, the threaded groove 17 and the convex ball 25 interact, causing the power collection cylinder 24 to rotate with the lifting main tube 15, gradually tightening the power storage coil spring 23 and storing potential energy.

[0060] This provides power reserves for the rapid rotation of the subsequent blade-cutting arm 21, ensuring cutting efficiency.

[0061] When the lifting main pipe 15 rises to its highest position, it squeezes the control head 38, which in turn pulls the push column 301 to extend through the control mechanism, squeezing the blocking head 31 and causing it to retract. At the same time, the control line 33 pulls the liquid storage box 32, causing the liquid in the liquid storage box 32 to enter the power supply box 34, which pushes the lifting box 36 to expand, thereby pushing the transmission arm 27 to rotate and causing the blade cutter arm 21 to open from the closed state to 90 degrees.

[0062] The leaf-cutting arm 21 is automatically deployed through a complex linkage mechanism, eliminating the need for manual intervention and improving the level of automation.

[0063] Leaf cutting arm 21 rapid rotation cutting:

[0064] After the leaf-cutting arm 21 is extended, the force-releasing ring 26 loses resistance. The elasticity of the energy-storing coil spring 23 drives the force-releasing ring 26 to rotate, which in turn drives the extension column 22 and the leaf-cutting arm 21 to rotate rapidly and cut the lawn blades covering the flat plate 14.

[0065] The rapidly rotating leaf-cutting arm 21 can efficiently cut lawn blades, clearing obstacles for subsequent irrigation operations.

[0066] Sprinkler head 16 extends for irrigation:

[0067] Simultaneously or after the leaf-cutting arm 21 cuts the lawn blades, the sprinkler head 16 extends from the flush plate 14 and begins to irrigate the lawn.

[0068] Ensure that irrigation water is sprayed evenly on the lawn to improve irrigation efficiency.

[0069] Lifting main tube 15 descends and the impeller:

[0070] After irrigation, the water pressure in the lifting pipe 15 decreases, and the reset cable 44 pulls it down. The blocking bladder 42 contracts due to the exhaust of the air bladder 45, allowing the drain outlet 41 to connect with the flush outlet 43. The remaining irrigation water sprays out from the flush outlet 43, impacting the flush plate 14 and removing broken lawn blades;

[0071] By utilizing the potential energy and residual water pressure energy during the descent of the lifting main pipe 15 for blade flushing, energy utilization efficiency is further improved.

[0072] Leaf-cutting arm 21 reset and standby;

[0073] After the lifting main pipe 15 has fully descended, the blade-cutting arm 21 returns to its initial state under the action of the energy-saving coil spring 23. The device returns to standby mode, waiting for the next irrigation command;

[0074] Ensure the device automatically resets to its initial state after each irrigation, preparing it for the next irrigation operation.

[0075] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
