Description

Technical Field

[0001] The invention belongs to the technical field of water hose winding, and in particular relates to a garden irrigation water hose winding device. Background Art

[0002] In garden and landscaping maintenance projects, watering and irrigation are crucial for maintaining healthy plant growth. As the primary water delivery tool, hoses are crucial for precisely delivering water to the areas in need. After irrigation operations are completed, hoses must be properly reeled for proper storage and efficient reuse.

[0003] The existing garden irrigation hose reeling device has the following problems:

[0004] The existing garden irrigation hose reeling device transports irrigation water to the irrigation area, because the water hose is wrapped around the outside of the through-hole, the water hoses squeeze each other, which reduces the space inside the water hose and makes it difficult for the irrigation water to circulate. The water hose wrapped around the outside of the roller needs to be completely removed, and then the water source needs to be connected to irrigate the irrigation area. As a result, the distance between the unwound water hose and the water source is longer, which increases the labor intensity of subsequent reeling of the water hose. In addition, after the traditional garden irrigation hose reeling device is used for irrigation, a large amount of irrigation water remains in the water hose, which makes the water hose prone to hydrolysis or oxidation in a humid environment, shortening the service life of the water hose. Therefore, it cannot meet the existing use requirements of the garden irrigation hose reeling device. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the existing technology, this solution provides a garden irrigation water hose winding device that can adaptively unwind the water hose according to the water source and the location of the irrigation area, and can air-dry the humid environment inside the water hose after use.

[0006] The technical solution adopted in this scheme is as follows: A garden irrigation hose winding device proposed in this scheme includes a winding frame, a movable wheel, a handrail frame, a winding mechanism, a segmentation mechanism and an air-drying mechanism, and the segmentation mechanism includes: multiple groups of water receiving components arranged at intervals along the length direction of the water hose, each group of water receiving components includes a water receiving pipe connected to the side wall of the water hose and a water receiving valve provided at the end of the water receiving pipe; a water supply component, provided at the bottom of the winding frame, including a retractable telescopic tube and a plug-in valve provided at the end of the telescopic tube, and the plug-in valve functions to selectively dock with any group of water receiving valves after unwinding; an extrusion sealing component, provided at the bottom of the winding frame, including a liftable arc-shaped plate, which functions to squeeze the unwound water hose to form a sealed partition; the air-drying mechanism includes an air pump, the exhaust end of which is connected to the water supply valve through a pipeline, and functions to inject air into the water hose after use.

[0007] As a further optimization of the present invention, the water receiving valve is normally in a closed state and is opened only when docked with the plug-in valve; the extrusion sealing assembly also includes: an extrusion rod passing through the bottom of the winding frame, and the arc plate is fixed to the top of the extrusion rod; an extrusion spring sleeved on the extrusion rod, connecting the arc plate and the winding frame; an extrusion electromagnet provided at the bottom end of the extrusion rod, which functions to adsorb the metal bottom wall of the winding frame when energized, so that the arc plate moves up to extrude the water hose.

[0008] Preferably, the water supply assembly further includes: a water supply cylinder symmetrically fixed to the inner wall of the winding frame; a water supply valve connecting the water supply cylinder with an external water source, one end of the telescopic tube is connected to the water supply cylinder, and the other end is connected to the plug valve.

[0009] Preferably, the winding mechanism includes: a winding assembly: a servo motor symmetrically arranged on both sides of the winding frame, a winding shaft passing through the winding frame and a winding roller fixed to one end of the winding shaft, and the winding roller is rotatably connected to the winding frame; a guide assembly: a guide frame arranged at one end of the winding frame, and a through strip groove is provided on its side wall; a water supply assembly: including a water hose wound around the winding roller, a water spray pipe passing through the strip groove and connected to the water hose, and a limiting slide and a tensioning spring arranged on the water spray pipe.

[0010] Preferably, the water delivery component also includes: multiple groups of annular rubber strips, equidistantly fixed to the outer wall of the water hose; a fixed plate fixed to the end of the water spray pipe, the limiting slide is slidably mounted on the water spray pipe, and the two ends of the tensioning and loosening spring are respectively connected to the fixed plate and the limiting slide.

[0011] Preferably, the width of the strip groove of the guide frame is smaller than the outer diameter of the limiting slide, which serves to intercept the limiting slide during winding, forcing the tensioning spring to compress so that the hose is tightly wound.

[0012] Preferably, it also includes a controller, which is fixed on the armrest and electrically connected to the servo motor, the extrusion electromagnet and the vacuum pump, and its functions are: controlling the extrusion electromagnet to be energized to form a water hose partition during irrigation; controlling the vacuum pump to supply air into the water hose after the irrigation is completed; and controlling the servo motor to rotate forward and reverse to realize the unwinding and rewinding of the water hose.

[0013] Preferably, the air-drying mechanism is linked with the segmentation mechanism: during regular maintenance, the controller controls the servo motor to unwind the water hose so that the rubber strip stretches the water hose, and at the same time starts the vacuum pump to inject air into the water hose through the nearest water valve.

[0014] The beneficial effects achieved by adopting the above structure are as follows:

[0015] Compared with the existing technology, this solution adopts a combination of a reeling mechanism and a segmenting mechanism. With the coordinated use of the reeling and unreeling assembly, the guide assembly, the water delivery assembly, the water receiving assembly, the water supply assembly and the extrusion sealing assembly, the segmenting mechanism achieves selective unreeling: the plug-in valve docks with any water receiving valve to prevent the hose from being completely unwound, reducing the difficulty of rewinding; the extrusion sealing assembly dynamically seals: the arc plate squeezes the unwound hose to prevent irrigation water from entering and reduce the wet area; the air drying mechanism actively dehumidifies: the vacuum pump injects air into the hose to inhibit material hydrolysis or oxidation;

[0016] According to the distance between the nozzle position and the irrigation water source, the water hose used for sprinkler irrigation is appropriately unwound, reducing the labor intensity of the rewinding operation. By setting multiple sets of water connecting pipes on the side wall of the water hose, the irrigation water is prevented from flowing from the inside of the water hose wound on the outside of the reeling roller, which can ensure the water supply of the water hose for sprinkler irrigation. Under the extrusion of the arc plate, the irrigation water flow can be prevented from flowing into the inside of the water hose wound on the outside of the reeling roller and not involved in the irrigation, reducing the air-drying area inside the water hose after the irrigation operation, and improving the reeling and unreeling efficiency of the water hose to a certain extent.

[0035] The water receiving assembly 20 includes a water receiving pipe 21 and a water receiving valve 22. Multiple groups of the water receiving pipes 21 are connected to the side wall of the water belt 13. The water receiving valve 22 is connected to the side of the water receiving pipe 21 away from the water belt 13. The normal state of the water receiving valve 22 is a closed setting; the water supply assembly 26 includes a water supply cylinder 27, a water supply valve 28, a telescopic pipe 29 and a plug-in valve 30. The water supply cylinder 27 is symmetrically arranged on the bottom inner wall of the winding frame 1. The water supply valve 28 is connected to one side of the water supply cylinder 27. The telescopic pipe 29 is connected to the water supply cylinder 27 away from the water supply On one side of the valve 28, the plug-in valve 30 is connected to the side of the telescopic tube 29 away from the water supply cylinder 27; the extrusion sealing assembly 33 includes an extrusion rod 32, an arc plate 31, an extrusion spring 25 and an extrusion electromagnet 24, the extrusion rod 32 passes through the bottom of the winding rack 1 below the water hose 13, the arc plate 31 is arranged on the upper wall of the extrusion rod 32, the extrusion spring 25 is arranged between the arc plate 31 on the outside of the extrusion rod 32 and the winding rack 1, the extrusion electromagnet 24 is arranged on the bottom wall of the extrusion rod 32, and the normal state of the extrusion spring 25 is a shortened setting.

[0036] A controller 23 is provided on the upper wall of the handrail frame 3 .

[0037] The controller 23 is electrically connected to the servo motor 6 , the extrusion electromagnet 24 , and the air pump 34 , respectively.

[0038] When in use, the operator holds the handrail 3 and pushes the winding frame 1 to the location of the irrigation water source through the moving wheel 2. The water supply valve 28 is connected to the water pump or faucet of the irrigation water source through a pipeline;

[0039] In the initial state, the tension spring 18 is shortened, the limiting slide 17 slides along the water spray pipe 15 close to the fixed plate 16, the water hose 13 is tightly wound around the outside of the winding roller 8, and the gap between the inner walls of the water hose 13 is reduced, preventing external moist air from entering the interior, thereby maintaining the dryness of the interior of the water hose 13;

[0040] The controller 23 controls the servo motor 6 to start, and the servo motor 6 drives the reeling shaft 7 to rotate by reversing the power end, and the reeling shaft 7 drives the water hose 13 to unwind through the reeling roller 8. The tension spring 18 is deformed and reset to drive the limit slide 17 away from the fixed plate 16. The operator pulls the water hose 13 through the water spray pipe 15, and the water hose 13 falls off from the outside of the reeling roller 8. The water hose 13 passes through the strip groove 11 and is laid on the ground. According to the distance between the water source and the irrigation position, the unwinding length of the water hose 13 is adjusted to prevent the water hose 13 from falling off from the outside of the reeling roller 8, which brings greater difficulties to the subsequent rewinding operation. When the unwinding length of the water hose 13 can allow the water spray pipe 15 to reach the sprinkler irrigation area, the controller 23 controls the servo motor 6 to stop the unwinding operation of the water hose 13;

[0041] The operator pulls the telescopic tube 29, which drives the plug valve 30 to connect with the water receiving pipe 21 unwound from the outside of the winding roller 8, opens the water supply valve 28, and the irrigation water enters the water supply cylinder 27 through the water supply valve 28 and then enters the plug valve 30 through the telescopic tube 29. The plug valve 30 transmits the irrigation water through the water receiving valve 22 and the water receiving pipe 21 to the water hose 13. The water hose 13 sprays the irrigation water to the area to be irrigated through the spray pipe 15. The other water receiving valves 22 that are not connected to the plug valve 30 are closed under normal conditions, so the irrigation water in the water hose 13 will not flow out.

[0042] In order to prevent the irrigation water from entering the water hose 13 that is not involved in the irrigation operation, the controller 23 controls the squeezing electromagnet 24 to start. The squeezing electromagnet 24 is energized to generate magnetism. The squeezing electromagnet 24 attracts the metal on the bottom wall of the winding frame 1 through magnetic force. The squeezing electromagnet 24 uses the deformation of the squeezing spring 25 to drive the curved plate 31 through the squeezing rod 32. The curved plate 31 squeezes the water hose 13, separating the water hose 13 that is not involved in the irrigation operation and is wound on the outside of the reeling roller 8 from the water hose 13 that is involved in the irrigation operation. The inner walls of the squeezed water hose 13 are tightly fitted together, thereby preventing the entry of sprinkler water.

[0043] After the water hose 13 performs the sprinkling irrigation operation, the water supply valve 28 is disconnected from the water pump or faucet of the irrigation water source, and the exhaust end of the air pump 34 is connected to the water supply valve 28 through a pipeline. The controller 23 controls the air pump 34 to start, and the air pump 34 blows gas into the water hose 13 involved in the irrigation operation to reduce the humidity inside the water hose 13 after the operation. Then, the docking plug valve 30 is separated from the water receiving valve 22, and the water receiving valve 22 is closed to prevent the water hose 13 from being stored in a humid environment for a long time and causing hydrolysis or oxidation reaction, which causes the water hose 13 to have reduced elasticity and increased brittleness, and thus bursting during use.

[0044] The controller 23 controls the extrusion electromagnet 24 to power off and demagnetize, and the extrusion spring 25 elastically resets to drive the arc plate 31 away from the water hose 13. The controller 23 controls the power end of the servo motor 6 to drive the reeling shaft 7 to rotate forward, and the reeling shaft 7 reels the water hose 13 through the reeling roller 8. The outer diameter of the limiting slide 17 is greater than the width of the strip groove 11. Under the limit of the strip groove 11, the limiting slide 17 is intercepted on the side of the guide frame 10 away from the water hose 13. With the deformation of the tension spring 18, the distance between the limiting slide 17 and the fixed plate 16 is shortened, and the water hose 13 is tightly wound around the outer side of the reeling roller 8. The inner walls of the water hose 13 fit together to block the entry of outside air, thereby completing the reeling operation of the water hose 13.

[0045] During routine maintenance of the water hose 13, it is necessary to dry the inside of the water hose 13 regularly. The controller 23 controls the servo motor 6 to start, and the servo motor 6 reverses to drive the winding roller 8 to unwind the water hose 13. After the tension from the water hose 13 is reduced on the limit slide 17, the tension spring 18 is deformed and reset to drive the limit slide 17 away from the fixed plate 16 until the tension spring 18 is reset to normal. The mutual squeezing force between the water hoses 13 disappears, and the multiple groups of rubber strips 14 arranged on the outside of the water hose 13 are deformed and reset to support the water hose. 13. The distance between the inner walls of the water hose 13 is increased to facilitate air circulation. The exhaust end of the vacuum pump 34 is connected to the water receiving valve 22 closest to the winding roller 8 through a pipeline. The water receiving valve 22 is opened, and the controller 23 controls the vacuum pump 34 to start. The vacuum pump 34 transports air to the inside of the water hose 13 through the exhaust end. Under the circulation of air, the moisture inside the water hose 13 evaporates with the flow of air, reducing the humidity inside the water hose 13, thereby keeping the water hose 13 stored in a relatively dry environment; just repeat the above operation when you use it next time.

The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present solution, designs a similar structure and embodiment without creatively designing, they shall fall within the scope of protection of the present solution.
