Description

TECHNICAL FIELD

[0001] The present application relates to the field of watering, more particularly, it relates to a building engineering greening sprinkling irrigation device. BACKGROUND

[0002] In the field of building 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 decoration and purification means. Green plants 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, the cultivation of green plants is not a one-time effort, and post-maintenance is also crucial. Among them, irrigation as a key link of green plant maintenance is directly related to the growth condition and survival rate of green plants. Therefore, the selection and use of appropriate irrigation devices are crucial for the maintenance of green plants.

[0004] The length of the grass leaves will gradually increase, and even may extend above the irrigation equipment. These grass leaves may not be removed or damaged when the equipment extends for irrigation, so after irrigation is completed, when the equipment tries to retract underground, the grass leaves may become an obstacle;

[0005] Secondly, some grass leaves may be loosened by wind or touch, and fall on the moving path of the irrigation equipment when it retracts, forming a physical obstruction. These fallen grass leaves may be stuck in the sliding part or mechanical structure of the equipment, causing increased friction and affecting the smooth retraction of the equipment;

[0006] Longer grass leaves may also deform due to compression or entanglement when the equipment retracts, further increasing the difficulty of equipment retraction. If this happens frequently, over time, it may cause the mechanical parts of the equipment to wear out more quickly, and even cause malfunctions, thereby affecting the long-term stability and automatic lifting function of the irrigation equipment.

[0045] As shown in Figure 9 The position corresponding to the blocking head 31 in the flush plate 14 is also provided with a clamping groove 302, the inside of the clamping groove 302 is provided with a push column 301, one side of the push column 301 is fixedly provided with a pull rope 39, and the push column 301 and the clamping groove 302 form an expansion structure, and the end of the pull rope 39 away from the push column 301 is provided with a joint control head 38.

[0046] The lower wall of the lifting main pipe 15 is fixedly provided with a water outlet 41 and a reset pull line 44, one end of the reset pull line 44 away from the lower wall of the lifting main pipe 15 is fixedly connected with the inside bottom wall of the sprinkler buried pipe 11, and a plurality of flushing openings 43 are in communication with the water outlet 41.

[0047] The channel between the water outlet 41 and the flushing opening 43 is a water channel, and the water channel is fixedly provided with a blocking capsule 42, the air inlet end of the blocking capsule 42 is provided with an air bag 45 through a pipeline, and the air bag 45 is fixedly connected with the lifting main pipe 15.

[0048] The device is in standby state, the flush plate 14 is flush with the green lawn land, the sprinkler pipe 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 potential energy is not stored by the force storage coil spring 23, the lifting main pipe 15 is located in the sprinkler buried pipe 11 and is in sliding connection with the inner through pipe 18, the blocking capsule 42 is in an uncharged state, and the water outlet 41 is blocked;

[0049] When the irrigation system is started, part of the water directly enters the inner through pipe 18 through the water supply pipe network 12, and the other part of the water flow enters between the outer wall of the inner through pipe 18 and the inner wall of the sprinkler buried pipe 11 through the water supply branch pipe 13, to provide water pressure required for the lifting of the lifting main pipe 15;

[0050] The main lifting pipe 15 rises with the water pressure, driving the leaf cutting mechanism on its upper part to move. The screw groove 17 interacts with the convex ball 25, causing the force collecting cylinder 24 to rotate as the main lifting pipe 15 rises. When the force collecting cylinder 24 rotates, it gradually tightens the force storage coil spring 23, storing potential energy, until the limit plate at the lowest end of the main lifting pipe 15 rises to the highest position, pressing the joint control head 38, which pulls the pull rope 39 through the joint control head 38, and the push column 301 extends through the pull rope 39, pressing the blocking head 31, which retracts into the force releasing ring 26.

[0051] At the same time, the blocking head 31 pulls the multiple joint control lines 33, which pull the bottom plate of the liquid storage box 32, pressing the liquid storage box 32, causing the liquid in the liquid storage box 32 to enter the force supply box 34, causing the lifting box 36 to expand in a fan shape, pushing the L-shaped transmission arm 27, causing the transmission arm 27 to rotate 90 degrees, and driving the leaf cutting arm 21 to rotate 90 degrees through the transmission arm 27, achieving the effect of unfolding the leaf cutting arm 21.

[0052] The leaf cutting arm 21 is opened from the closed state to 90 degrees through the transmission arm 27, at which point the force releasing ring 26 loses resistance, rotates through the elasticity of the force storage coil spring 23, drives the extension column 22 to rotate through the force releasing ring 26, and drives the leaf cutting arm 21 to rotate quickly through the extension column 22, cutting the lawn leaves covering the leveling plate 14.

[0053] The sprinkler pipe head 16 extends from the leveling plate 14 to start irrigating the lawn. After irrigation is completed, the water pressure in the main lifting pipe 15 decreases, the reset pull line 44 pulls it down, the blocking bag 42 shrinks due to the air bag 45 exhausting, allowing the water outlet 41 to communicate with the flushing outlet 43, and the residual irrigation water is sprayed out of the flushing outlet 43, impacting the leveling plate 14 and removing the broken lawn leaves.

[0054] After the main lifting pipe 15 is completely lowered, the leaf cutting arm 21 is reset to the initial state under the action of the force storage coil spring 23, and the device returns to standby state, waiting for the next irrigation command.

[0055] Standby state: When the device is in standby state, the leveling plate 14 is flush with the green lawn land, the sprinkler pipe head 16 is hidden below the leveling plate 14, and the leaf cutting arm 21 of the leaf cleaning mechanism 2 is in the closed state. The force storage coil spring 23 does not store potential energy, the main lifting pipe 15 is located in the sprinkler buried pipe 11 and is slidingly connected with the inner pipe 18. The blocking bag 42 is in the un-inflated state, and the water outlet 41 is blocked.

[0056] The device is kept low and hidden, does not hinder the beauty of the lawn, and ensures that the leaf cleaning mechanism 2 does not operate by mistake when in standby state.

[0057] Irrigation system starts and the lifting main pipe 15 rises: when the irrigation system starts, water enters the inner pipe 18 and the space between the inner pipe 18 and the buried pipe 11 through the water supply network 12 and the water supply branch pipe 13, providing the water pressure required for the lifting main pipe 15 to rise, and the lifting main pipe 15 rises in response to the water pressure, driving the leaf cleaning mechanism 2 on the upper part of the lifting main pipe 15 to move;

[0058] The lifting main pipe 15 is driven to rise by the pressure of the irrigation water itself, without the need for an additional power source, saving energy and protecting the environment.

[0059] The force collecting cylinder 24 rotates and stores potential energy: during the rising process of the lifting main pipe 15, the threaded groove 17 interacts with the convex ball 25, causing the force collecting cylinder 24 to rotate with the lifting main pipe 15, gradually tightening the power storage coil spring 23 and storing potential energy;

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

[0061] The blocking head 31 retracts and the leaf cutting arm 21 expands: when the lifting main pipe 15 rises to the highest point, the control head 38 is pressed, pulling the push rod 301 out through the control mechanism, pressing the blocking head 31 to retract, and at the same time, pulling the liquid storage box 32 through the control line 33, causing the liquid in the liquid storage box 32 to enter the force supply box 34, expanding the lifting box 36, and then driving the transmission arm 27 to rotate, driving the leaf cutting arm 21 to open from the closed state to 90 degrees;

[0062] The automatic expansion of the leaf cutting arm 21 is achieved through a complex linkage mechanism, without the need for manual intervention, improving the degree of automation.

[0063] Rapid rotation of the leaf cutting arm 21 for cutting:

[0064] After the leaf cutting arm 21 expands, the force releasing ring 26 loses resistance, and is driven to rotate by the elasticity of the power storage coil spring 23, and then drives the extension column 22 and the leaf cutting arm 21 to rotate rapidly for cutting the lawn blades covering the leveling plate 14;

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

[0066] The sprinkler pipe head 16 extends and irrigates:

[0067] While or after the leaf cutting arm 21 cuts the lawn blades, the sprinkler pipe head 16 extends from the leveling plate 14 and starts irrigating the lawn;

[0068] This ensures that the irrigation water can be evenly sprayed on the lawn, improving irrigation efficiency.

[0069] The lifting main pipe 15 descends and the leaves are flushed:

[0070] After irrigation, the water pressure in the lifting main pipe 15 decreases, and the reset pull wire 44 pulls it down. The blocking bag 42 shrinks due to the air bag 45 exhausting, allowing the water outlet 41 to communicate with the flushing outlet 43. The residual irrigation water is sprayed out of the flushing outlet 43, impacting the flush plate 14 and removing the broken lawn blades;

[0071] The leaf flushing operation is performed by using the potential energy and residual water pressure when the lifting main pipe 15 is lowered, further improving the energy utilization efficiency.

[0072] The cutting arm 21 is reset and waits;

[0073] After the lifting main pipe 15 is completely lowered, the cutting arm 21 is reset to the initial state under the action of the force storage coil spring 23. The device returns to the standby state and waits for the next irrigation instruction;

[0074] It is ensured that the device can be automatically reset to the initial state after each irrigation, preparing for the next irrigation operation.

[0075] The above describes the embodiments of the present embodiment, but the present embodiment is not limited to the specific embodiments described above, which are only illustrative and not restrictive. Those skilled in the art can make many forms under the inspiration of the present embodiment, which are all within the protection of the present embodiment.
