Description

Technical Field

[0001] This utility model relates to the field of garden drip irrigation technology, and in particular to a water-saving garden drip irrigation device. Background Technology

[0002] Drip irrigation delivers water through pipes to the soil near the roots of crops. In landscaping, drip irrigation allows water to drip into the soil at a constant, low flow rate, ensuring that the water reaches the plant root zone at a very slow speed, thus achieving water conservation while maintaining irrigation effectiveness.

[0003] A search revealed that the Chinese patent "An Automatic Water-Saving Drip Irrigation Device for Landscaping" (authorization announcement number CN211983044U) incorporates a first filter screen within a second connecting pipe. This filter screen effectively prevents impurities from clogging the drip irrigation head. Furthermore, a connecting water pipe is installed on the second connecting pipe. When the first electric valve is closed, the second and third electric valves and the water pump are opened. Water from the storage tank flows through the connecting water pipe, passes through the second filter screen, and then flows from the right end of the first filter screen into the second connecting pipe to rinse the first filter screen, thus improving the utilization rate of the first filter screen.

[0004] Although the above application can clean the first filter screen, the cleaning solution is filtered through the second filter screen during cleaning. When the impurities attached to the second filter screen increase, it is easy to cause the mesh to become clogged, which affects the flow of the cleaning solution through the first filter screen and reduces the cleaning effect on the first filter plate.

[0005] Therefore, a water-saving drip irrigation device for gardens is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a water-saving drip irrigation device for gardens to solve the above-mentioned problems. It improves the problem that when the impurities attached to the second filter screen increase, the mesh is easily clogged, which affects the flow of the water solution through the first filter screen during cleaning and reduces the cleaning effect on the first filter plate.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a garden drip irrigation water-saving device, comprising: a water tank, wherein a water pump is installed at the lower end of the surface of the water tank; a drip irrigation mechanism, wherein the drip irrigation mechanism includes a first three-way pipe, a second three-way pipe and two connecting pipes, wherein the two ends of the first three-way pipe and the two ends of the second three-way pipe are respectively connected to the two connecting pipes, the other end of the first three-way pipe is connected to the outlet of the water pump, and a plurality of drip irrigation heads are connected to the lower end of the surface of the second three-way pipe; a filter plate is fixedly connected to the inner wall of the connecting pipe, and a baffle is rotatably connected to the inner wall of the connecting pipe; a fixed pipe is connected between the two connecting pipes, and a first solenoid valve is provided on the surface of the fixed pipe.

[0008] Preferably, the top ends of both baffle shafts extend through a connecting pipe and are fixedly connected to pulleys, with a drive belt connecting the two pulleys. This facilitates the synchronous rotation of the two baffles within the connecting pipe.

[0009] Preferably, a brush is rotatably connected to one end of the filter plate, and a rotating rod is rotatably connected to the inner wall of the connecting pipe. A bevel gear is rotatably connected to the bottom end of the rotating rod and the other end of the filter plate. One end of the brush's rotating shaft passes through the filter plate and is fixedly connected to one end of one of the bevel gears. By driving the corresponding brush to rotate, it is beneficial to clean the end of the filter plate that intercepts impurities. Simultaneously, the aqueous solution introduced through the fixed pipe flows from the other end of the filter plate towards the brush for rinsing, which facilitates simultaneous rinsing of both the brush and the filter plate, enhancing the cleaning effect on the filter plate and preventing impurities from remaining during the brush cleaning process.

[0010] Preferably, the lower end of the connecting pipe is connected to a drain pipe, and a sealing plug is installed at the bottom end of the drain pipe. When the connecting pipe guides water for drip irrigation, the sealing plug is used to seal the drain pipe, ensuring the stable operation of the drip irrigation operation.

[0011] Preferably, a protective frame is fixedly connected to the upper surface of the connecting pipe, and a knob is fixedly connected to the top of one of the pulleys through the protective frame. A locking rod is slidably connected to the inner wall of the knob, and two circular holes are opened at the top of the protective frame. This facilitates limiting the knob during device operation, thereby ensuring the stability of the baffle during operation.

[0012] Preferably, the top end of the rotating rod extends through the protective frame and is threaded with a bolt, and the top end of the protective frame has a threaded hole. This facilitates the fixing of the rotating rod and ensures the stability of the brush during device operation.

[0013] Preferably, a sealing ring, which is a rubber component, is fixedly connected to one end of the baffle. This ensures the sealing performance of the sealing plate when blocking the connecting pipe.

[0014] The beneficial effects of this utility model are:

[0015] 1. The drip irrigation mechanism described above achieves drip irrigation through a first three-way pipe, a connecting pipe, a second three-way pipe, and a drip head. By setting up two connecting pipes and fixing the pipes, the filter plate in one connecting pipe filters the water while simultaneously cleaning the filter plate in the other connecting pipe. This intermittent, staggered cleaning of the filter plates in the two connecting pipes prevents the accumulation of impurities on the two filter plates during operation, thus avoiding blockage. This keeps the two filter plates clean during operation, ensuring the flowability of the water solution as it passes through the filter plates. Simultaneously, it ensures continuous drip irrigation operation of the drip head, guaranteeing the drip irrigation effect.

[0016] 2. When cleaning the filter plate, driving the corresponding brush to rotate helps to clean the end of the filter plate that intercepts impurities. At the same time, the aqueous solution introduced by the fixed pipe flows from the other end of the filter plate towards the brush to rinse it, which helps to rinse the brush and the filter plate at the same time, enhances the cleaning effect of the filter plate, and avoids impurities from being left behind during the brush cleaning process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-5As shown, a garden drip irrigation water-saving device includes: a water tank 100, with a water pump 200 installed at the lower end of the surface of the water tank 100; a drip irrigation mechanism 300, which includes a first three-way pipe 310, a second three-way pipe 320, and two connecting pipes 330. The two ends of the first three-way pipe 310 and the two ends of the second three-way pipe 320 are respectively connected to the two connecting pipes 330. The other end of the first three-way pipe 310 is connected to the outlet of the water pump 200. The lower end of the surface of the second three-way pipe 320 is connected to a plurality of drip irrigation heads 340. A filter plate 350 is fixedly connected to the inner wall of the connecting pipe 330, and a baffle 360 ​​is rotatably connected to the inner wall of the connecting pipe 330. A fixed pipe 370 is connected between the two connecting pipes 330, and a first solenoid valve 371 is provided on the surface of the fixed pipe 370.

[0025] In this embodiment, an inlet pipe is installed on the upper surface of the water tank 100. When it is necessary to add aqueous solution to the water tank 100, the inlet pipe is connected to an external water source. A second solenoid valve is installed on the surface of the first three-way pipe 310. When the water pump 200 is started by controlling it, the water pump 200 will introduce the aqueous solution in the water tank 100 into the first three-way pipe 310. The flow rate can be controlled by the second solenoid valve.

[0026] In the initial state, the two baffles 360 in one of the connecting pipes 330 are perpendicular to the filter plate 350, the two baffles 360 in the other connecting pipe are parallel to the filter plate 350, and the first solenoid valve 371 is in the closed state.

[0027] like Figure 3 and Figure 5 As shown, the top ends of the two baffles 360 rotating shafts both extend through the connecting pipe 330 and are fixedly connected to pulleys 361, and a transmission belt 362 is connected between the two pulleys 361.

[0028] In this embodiment, when one of the pulleys 361 is rotated to drive the corresponding baffle 360 ​​to rotate, the other pulley 361 will drive the other baffle 360 ​​to rotate synchronously under the action of the transmission belt 362, thereby achieving synchronous rotation of the two baffles 360 in the connecting pipe 330.

[0029] like Figure 4 As shown, a brush 351 is rotatably connected to one end of the filter plate 350, and a rotating rod 352 is rotatably connected to the inner wall of the connecting pipe 330. A bevel gear 353 is rotatably connected to the bottom end of the rotating rod 352 and the other end of the filter plate 350. One end of the rotating shaft of the brush 351 passes through the filter plate 350 and is fixedly connected to one end of one of the bevel gears 353.

[0030] In this embodiment, a circular frame is fixedly connected to the other end of the filter plate 350. Two bevel gears 353 are disposed inside the circular frame. The surface of the rotating shaft of one of the bevel gears 353 is rotatably connected to the inner wall of the circular frame with the surface of the rotating rod 352. The surfaces of the two bevel gears 353 are meshed together. Therefore, when the rotating rod 352 is rotated, it will drive the two bevel gears 353 to rotate synchronously and drive the brush 351 to rotate. The bristles of the brush 351 are attached to the surface of the filter plate 350.

[0031] like Figure 3 As shown, the lower end of the surface of the connecting pipe 330 is connected to the drain pipe 331, and a sealing plug is installed at the bottom end of the drain pipe 331.

[0032] In this embodiment, when the device is in its initial state, the sealing plug blocks the drain pipe 331, thereby ensuring normal drip irrigation operation.

[0033] like Figure 5 As shown, a protective frame 380 is fixedly connected to the upper surface of the connecting pipe 330. The top of one of the pulleys 361 passes through the protective frame 380 and is fixedly connected to a knob 363. A locking rod 364 is slidably connected to the inner wall of the knob 363. Two round holes are opened at the top of the protective frame 380.

[0034] In this embodiment, the included angle between the center points of the two circular holes is 90 degrees. When the device is running, the locking rod 364 engages with the circular hole to limit the rotation knob 363, thereby limiting the pulley 361 and the baffle 360.

[0035] like Figure 4 As shown, the top of the rotating rod 352 extends through the protective frame 380 and is threaded with a bolt 354. The top of the protective frame 380 has a threaded hole.

[0036] In this embodiment, the rotating rod 352 is fixed by threading the bolt 354 into the threaded hole. When it is necessary to rotate the rotating rod 352, the connection between the bolt 354 and the threaded hole can be released.

[0037] like Figure 5 As shown, a sealing ring 365 is fixedly connected to one end of the baffle 360, and the sealing ring 365 is a rubber component.

[0038] In this embodiment, when the baffle 360 ​​and the filter plate 350 are in a parallel state, the surface of the sealing ring 365 is in contact with the inner wall of the connecting pipe 330.

[0039] When in use, the water pump 200 is started by the controller to introduce the aqueous solution in the water tank 100 into the first three-way pipe 310 and into one of the connecting pipes 330. At this time, the filter plate 350 in the connecting pipe 330 filters the aqueous solution. The filtered aqueous solution enters the second three-way pipe 320 and achieves drip irrigation through multiple drip heads 340.

[0040] When cleaning the filter plate 350 inside one of the connecting pipes 330, firstly, the pulley 361 and drive belt 362 on the other connecting pipe 330 cause the two baffles 360 inside the other connecting pipe 330 to rotate synchronously and be perpendicular to the filter plate 350. At this time, the aqueous solution will simultaneously enter the other connecting pipe 330, and the filter plate 350 inside the other connecting pipe 330 will filter the aqueous solution. Simultaneously, the two baffles 360 inside one of the connecting pipes 330 are rotated to be parallel to the filter plate 350, thereby blocking the connecting pipe 330. At this time, the first three-way pipe 3... The aqueous solution introduced at 10 cannot pass through the connecting pipe 330. After this operation is completed, the first solenoid valve 371 is opened, so that the aqueous solution filtered by the other connecting pipe 330 enters the second three-way pipe 320 for drip irrigation. At the same time, it enters one of the connecting pipes 330 through the fixed pipe 370 and rinses the filter plate 350. The sealing plug of the corresponding drain pipe 331 is opened to discharge the cleaning aqueous solution and impurities. During the cleaning, the brush 351 on the filter plate 350 is driven to rotate to clean the filter plate 350. After cleaning, the rotating rod 352 is fixed and the first solenoid valve 371 is closed.

[0041] When it is necessary to clean the filter plate 350 inside another connecting pipe 330, the operation shall be carried out in accordance with the above principles and steps.

[0042] It should be noted that the water pumps, solenoid valves, etc. mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the water pumps and solenoid valves can be powered by built-in power supplies or mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
