Description

Technical Field

[0001] This invention relates to the field of greening fence technology, specifically to a greening fence that integrates rainwater collection and irrigation for greening projects. Background Technology

[0002] To maintain the beauty of the garden, users often carry out maintenance. To prevent pedestrians from entering the maintenance area, people often use fences to block the surrounding area. However, traditional garden maintenance fences cannot collect and reuse rainwater, and cannot maximize resource utilization. People have to connect water pipes to spray water on the garden plants, which not only increases costs but also increases the workload of people.

[0003] To this end, Chinese Patent No. CN117108135A published a "Green Fence with Integrated Rainwater Collection and Irrigation for Greening Projects". Its main structure includes two bases, with a lower water collection pipe and a support column fixedly connected to the top of each base. An upper water collection pipe is fixedly connected to the top of a connecting plate. An upper drainage pipe is fixedly connected to one side of the bottom of the upper water collection pipe. A lower drainage pipe is fixedly connected to one side of the bottom of the lower water collection pipe. Multiple nozzles are fixedly connected to one side of both the upper and lower drainage pipes. A support plate is fixedly connected to the top of the upper water collection pipe and the support column. A water collection tank is fixedly connected to the top of the support plate. A cleaning component is provided on the top of the water collection tank. This greening project uses an integrated rainwater collection and irrigation fence. When irrigation is needed, a dual-shaft motor starts and drives the first rotating shaft to rotate. When the first rotating shaft rotates, it drives the first bevel gear to rotate. The first bevel gear drives the sliding sleeve to rotate inside the upper and lower supports. When the sliding sleeve rotates, it drives the threaded sleeve to slide downward inside the upper water collection pipe. This causes the threaded sleeve to move the upper push plate, and the upper push plate drives the two first water baffles to descend. The first water baffles block the through holes and push the rainwater down. At this time, the control valve is in the closed state, and the solenoid valve connecting the lower water collection pipe and the upper drainage pipe is opened, allowing rainwater to enter the upper drainage pipe and spray out from multiple nozzles to irrigate the green plants.

[0004] It is obvious that the rainwater harvesting and irrigation integrated green fence used in the above-mentioned greening project requires a power source, which will undoubtedly increase the cost of use. At the same time, the water collection tank is exposed, resulting in a relatively low water accumulation. Therefore, its practicality is low. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A greening fence integrating rainwater collection and irrigation for greening projects is provided. In the area where the fence is needed, a corresponding pre-buried trench is dug, and then the water collection tank 11 is buried inside the pre-buried trench. The second longitudinal railing 16, the first longitudinal railing 14, the third longitudinal railing 18 and the horizontal railing 19 can play the role of fence.

[0021] To achieve guided rainwater collection, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4A collection-type fencing mechanism 1 needs to be installed, which includes a rainwater collection tank 11 that can be buried underground to store rainwater, a rainwater diversion tank 17 located above ground to collect rainwater, a second longitudinal guardrail 16 located between the collection tank 11 and the rainwater diversion tank 17 for longitudinal rainwater flow, and a horizontal guardrail 19 located between the second longitudinal guardrail 16 for rainwater discharge. When it rains, rainwater is collected through the rainwater diversion tank 17, and then, under the effect of gravity, the rainwater flows sequentially through the third longitudinal guardrail 16. The rainwater enters the rainwater storage chamber 12 through the railing 18 and the first longitudinal railing 14, and is stored in the rainwater storage chamber 12. When it is necessary to irrigate the surrounding green plants, the high-pressure gas entering the rainwater storage chamber 12 will generate gas pressure on the rainwater. Under the action of gas pressure, the rainwater located in the rainwater storage chamber 12 will be sprayed outwards through the rainwater flow pipe 15, the second longitudinal railing 16, the horizontal railing 19 and the water spray hole 110, thereby achieving the effect of guiding and collecting rainwater.

[0022] For details regarding the specific structure of the collection-type fence mechanism 1, please refer to [link / reference]. Figure 3 and Figure 4 The system includes a rainwater storage chamber 12 located inside a rainwater collection tank 11 for storing rainwater. A first gas flow hole 13, connecting the external space and the rainwater storage chamber 12, is located in the middle of one side of the rainwater collection tank 11. First longitudinal railings 14, with open tops and bottoms connecting to the top of the rainwater storage chamber 12, are located on the top of the rainwater storage chamber 12. A rainwater flow pipe 15, integrally formed with the rainwater collection tank 11, is located at the top of the rainwater storage chamber 12. A second longitudinal railing 16, integrally formed with and extending upwards, is located on the upper surface of the rainwater collection tank 11. The hollow structure inside the rainwater flow pipe 15 and the hollow structure inside the second longitudinal railing 16 are interconnected. Multiple integrally formed railings are located on the middle section of the second longitudinal railing 16. A horizontal railing 19 is provided, and the hollow structure inside the horizontal railing 19 is connected to the hollow structure inside the second longitudinal railing 16. A water spray hole 110 for draining rainwater is provided on one side of the horizontal railing 19. A rainwater diversion box 17 for collecting rainwater is fixedly installed at the top of the second longitudinal railing 16. A third longitudinal railing 18, which is integral with the rainwater diversion box 17 and connected to the hollow structure inside the rainwater diversion box 17, is provided at the bottom of the rainwater diversion box 17. There is a gap for rainwater flow between the bottom end of the rainwater flow pipe 15 and the bottom end of the rainwater storage cavity 12. The third longitudinal railing 18 is located directly above the first longitudinal railing 14, and the axis of the third longitudinal railing 18 is on the same vertical line as the axis of the first longitudinal railing 14.

[0023] To achieve manual pedal-assisted pressure output and thus reduce operating costs, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 and Figure 6 A rebound-type gas compression mechanism 2 needs to be installed. Inside, there is a first longitudinal hollow shell 21 fixedly installed on one side of the water collection tank 11 and hollow inside; a piston plate 29 placed inside the first longitudinal hollow shell 21 that compresses gas during reciprocating motion; a foot pedal 211 that moves the piston plate 29 downwards when stepped on; and a first gas check valve 26 and a second gas check valve 27 that allow external gas to enter the water collection tank 11 unidirectionally. When the foot pedal 211 is manually circulated, the piston plate 29 continuously reciprocates under the rebound effect of the first helical spring 212. Simultaneously, external gas continuously enters the gas compression chamber 22 and is output to the first gas flow hole 13 through the curved docking channel 24. Due to the action of the first gas check valve 26 and the second gas check valve 27, the gas cannot flow back, thus achieving unidirectional gas pressure output until the gas pressure entering the rainwater storage chamber 12 meets the rated value.

[0024] For details regarding the specific structure of the spring-loaded gas compression mechanism 2, please refer to [link / reference needed]. Figure 5 and Figure 6The system includes a gas compression chamber 22 disposed inside a first longitudinal hollow outer shell 21. A gas limiting flow chamber 23 is disposed at the bottom end of the first longitudinal hollow outer shell 21 located within the gas compression chamber 22. A rod through-hole 28 is disposed at the top end of the first longitudinal hollow outer shell 21, connecting the external space and the top end of the gas compression chamber 22. A curved docking channel 24, integrally formed with the first longitudinal hollow outer shell 21 and connecting the bottom end of the gas limiting flow chamber 23 and a first gas flow hole 13, is disposed at the bottom end of the first longitudinal hollow outer shell 21. A gas inflow channel 25, connecting the external space and the side of the gas limiting flow chamber 23, is disposed on one side of the first longitudinal hollow outer shell 21. A first gas check valve 26 and a second gas check valve 27 are respectively installed inside the curved docking channel 24 and the gas inflow channel 25. The first longitudinal hollow outer shell 21, located within the gas limiting flow chamber 22, has a gas limiting flow chamber 23 disposed at the bottom end of the first longitudinal hollow outer shell 21. Inside the 3, there is a piston plate 29 that can move axially along the gas limiting flow cavity 23. A longitudinal telescopic rod 210 with a through-hole 28 is fixedly installed on the upper surface of the piston plate 29. A foot pedal 211 is fixedly installed at the top of the longitudinal telescopic rod 210. A first helical spring 212 in a compressed state is placed around the rod 210 between the top of the first longitudinal hollow shell 21 and the bottom of the foot pedal 211. The cross-sectional shape of the through-hole 28 is consistent with the cross-sectional shape of the longitudinal telescopic rod 210, both being polygonal structures. The cross-sectional dimensions of the through-hole 28 match the cross-sectional dimensions of the longitudinal telescopic rod 210. The first gas check valve 26 and the second gas check valve 27 can control the gas to flow unidirectionally from the outside space into the interior of the first gas flow hole 13.

[0025] To achieve unidirectional liquid transport and prevent gas leakage, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 7 and Figure 8 A liquid unidirectional flow control mechanism 3 needs to be set up. Inside the mechanism, there is a second longitudinal hollow shell 31 installed between the third longitudinal railing 18 and the first longitudinal railing 14 and which is hollow inside; an internal valve plate 37 placed inside the second longitudinal hollow shell 31 and which can move downward under liquid pressure; and a second helical spring 311 that exerts an upward elastic force on the internal valve plate 37. When the liquid pressure inside the third longitudinal railing 18 is greater than the elastic pressure of the second helical spring 311, the internal valve plate 37 will move downward, and the rainwater will flow downward through the movement gap of the internal valve plate 37 and the second gas flow hole 35, thereby realizing the unidirectional delivery of liquid. The high-pressure gas inside the rainwater storage chamber 12 will not leak upward, thus realizing the unidirectional delivery of liquid and preventing gas leakage.

[0026] For details regarding the specific structure of the liquid unidirectional flow control mechanism 3, please refer to [link / reference needed]. Figure 7 and Figure 8 This includes a longitudinal component movable cavity 32 disposed inside a second longitudinal hollow outer shell 31. The bottom end of the second longitudinal hollow outer shell 31 is provided with a first docking channel 33 fixedly installed at the top of a first longitudinal railing 14. The first docking channel 33 has a second gas flow hole 35 connecting the bottom end of the longitudinal component movable cavity 32 and the hollow structure inside the first longitudinal railing 14. The top end of the second longitudinal hollow outer shell 31 is provided with a second docking channel 34 fixedly installed at the bottom end of a third longitudinal railing 18. The second docking channel 34 has a third gas flow hole 36 connecting the top end of the longitudinal component movable cavity 32 and the hollow structure inside the third longitudinal railing 18. The second longitudinal hollow outer shell 31 is located in the longitudinal component movable cavity... An internal valve plate 37 capable of moving along its axial direction is housed inside the moving cavity 32. The circumferential surface of the internal valve plate 37 is provided with multiple gas flow grooves 310 for gas flow. The upper surface of the internal valve plate 37 is provided with an annular embedding groove 38 with a concave structure. An annular sealing ring 39 is embedded inside the annular embedding groove 38. A second helical spring 311 in a compressed state is placed at the bottom of the internal valve plate 37. The thickness of the annular sealing ring 39 is greater than the depth of the annular embedding groove 38, and the structural radius of the inner ring of the annular sealing ring 39 is greater than the structural radius of the third gas flow hole 36. The structural radius of the outer ring of the annular sealing ring 39 is smaller than the distance between the center point of the internal valve plate 37 and the gas flow groove 310.

[0027] In use, a pre-buried trench is dug in the area requiring fencing, and then the water collection tank 11 is buried inside the trench. The second longitudinal guardrail 16, the first longitudinal guardrail 14, the third longitudinal guardrail 18, and the horizontal guardrail 19 serve as a fence. When it rains, rainwater is collected through the rainwater diversion box 17, and then, under gravity, the rainwater flows sequentially through the third longitudinal guardrail 18 and the first longitudinal guardrail 14 into the rainwater storage chamber 12, where it is stored. When the foot pedal 211 is manually operated in a cyclical manner, the piston plate 29 will engage with the first helical spring 212. Under the rebound effect, it continuously performs reciprocating motion. At the same time, external gas continuously enters the interior of the gas compression chamber 22 and outputs gas to the first gas flow hole 13 through the curved docking channel 24. Due to the action of the first gas one-way valve 26 and the second gas one-way valve 27, the gas cannot flow back, thereby realizing one-way gas pressure output until the gas pressure entering the rainwater storage chamber 12 meets the rated value. Under the action of air pressure, the rainwater located inside the rainwater storage chamber 12 will sequentially spray and irrigate the surrounding area through the rainwater flow pipe 15, the second longitudinal railing 16, the horizontal railing 19 and the spray hole 110.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
