Description

Technical Field

[0001] The invention relates to the technical field of garden maintenance, in particular to a garden landscape maintenance water-saving irrigation device. Background Art

[0002] Gardening refers to the use of engineering technology and artistic means in a certain area to transform the terrain and plant trees, flowers and plants, which need to be irrigated and maintained in daily maintenance;

[0003] After searching, the Chinese patent publication number CN115885815B discloses a garden landscape maintenance water-saving irrigation device and its use method. Although the device can squeeze the connecting plate by the water pressure in the spray hose, as the connecting plate is moved to both sides, the first spring sheet is concave, and the nozzle and the connecting sleeve are sealed by the rubber sealing sheet to prevent water from entering. Subsequently, the nozzle squeezes the spring under the squeezing force of the water pressure, so that the nozzle extends outward from the connecting sleeve to irrigate the garden plants, but due to the influence of water pressure fluctuations, the irrigation range of the nozzle of the device is unstable, which in turn affects the stability of the irrigation range;

[0004] After searching, the Chinese patent publication number CN218959687U discloses a garden landscape irrigation device. Although the device enables the through hole to be opened and closed as needed, the accumulated water inside the water pipe and the nozzle can be effectively discharged, solving the problem that the inside of the nozzle and the water pipe may be damaged by freezing and cracking due to internal water accumulation in winter, the water supply method of the device is single. When the water flow in the water supply pipeline is small or the water is cut off, the irrigation device cannot be used normally. Summary of the invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a garden landscape maintenance water-saving irrigation device, comprising:

[0007] Water pump, which is used to supply water to the entire irrigation system;

[0008] Also includes;

[0009] A water inlet, which is arranged at one end of the top of the water pump;

[0010] A tee pipe, one end of which is connected to the output end of the water pump;

When the external water supply is sufficient, the valve cage can slide toward one end of the water tank under the push of the water pressure inside the tee pipe and the push of the first spring, and one end of the valve cage can fit with the limiting ring, thereby closing the compensation tube.

[0018] Preferably, the outer wall surface of the valve cage is distributed with strip holes at equal intervals in a circular shape, one end of the valve cage is open, and the other end of the valve cage is closed, and both ends of the valve cage are provided with annular protruding structures on the outside, and there is a gap between one end of the valve cage and the inner wall of the compensation tube, and the other end of the valve cage is in sliding contact with the inner wall of the compensation tube. When the external water supply is insufficient or the water supply is cut off, the water pressure inside the three-way pipe will decrease, and then under the action of the water pressure inside the water tank, the valve cage can be pushed to compress the first spring, so that one end of the valve cage can extend from the inside of the limit ring, so that the water inside the water tank can flow into the three-way pipe through the holes on the outer wall of the valve cage.

[0019] Preferably, the collecting mechanism includes a water tank, one end of the top and bottom of the water tank is welded to the compensation pipe, a guide plate is arranged inside the water tank, the guide plate is arranged in an inclined state, both sides of the guide plate are rotatably connected to the inner wall of the water tank, a filter plate is arranged above one end of the guide plate, strip-shaped filter holes are opened on the surface of the filter plate, and the filter plate is welded to the inner wall of the water tank. The open design of the top of the water tank enables the water tank to collect rainwater. When collecting rainwater, the rainwater will fall onto the guide plate, and then the dust and impurities in the rainwater can be precipitated and collected through the grooves on the surface of the guide plate, and then gathered at the bottom end of the guide plate after being filtered by the filter plate.

[0020] Preferably, two connecting blocks are welded on the top of one end of the water tank, and the connecting blocks are rotatably connected to both ends of the first connecting rod. The first connecting rod is welded to the top end of the telescopic rod, and a second spring is mounted on the outside of the bottom end of the telescopic rod. The bottom end of the telescopic rod is welded to the second connecting rod, and both ends of the second connecting rod are rotatably connected to the guide plate. Under the action of the second spring, the guide plate can be flipped and reset to keep the water storage space at the bottom of the water tank closed, which is beneficial for the device to collect rainwater, thereby saving water, and at the same time can greatly reduce the evaporation loss of water inside the water tank through the guide plate.

[0022] Preferably, grooves are provided on the surface of the guide plate, and the grooves on the surface of the guide plate are arranged in a straight line with equal spacing. The edge of one end of the top of the water tank is arranged in a slope shape.

When the water pressure is high, the water inside the spray head will push the lifting tube to move upward and compress the third spring, so that the hole groove on the outer wall of the lifting tube can be connected with the second water outlet hole, so that water can be discharged through the second water outlet hole. When the water pressure is relatively low, the lifting tube can be moved to the bottommost end inside the spray head under the push of the third spring, so that the interior of the lifting tube can be connected with the first water outlet hole.

When the water volume inside the pipeline is the same, the first water outlet hole has a longer spraying distance due to its small aperture, and the second water outlet hole has a shorter spraying distance due to its large aperture.

[0025] Preferably, a pressure block is provided on the top of the third spring, the outer wall of the pressure block is in sliding contact with the inner wall of the sprinkler head, the top of the pressure block is rotatably connected to the bottom of the threaded rod, the threaded rod is threadedly connected to one end of the top of the sprinkler head, and a knob is welded on the top of the threaded rod, and by turning the knob, the knob can drive the threaded rod to rotate, and the threaded rod can drive the pressure block to move downward, so that the pressure block can squeeze the third spring, so that the pressure of the third spring can be adjusted.

[0026] The present invention provides a water-saving irrigation device for garden landscape maintenance, which has the following beneficial effects:

[0027] (1) A garden landscape maintenance water-saving irrigation device, which establishes a connection with an external water source through a water pump and realizes water flow control by opening a solenoid valve; the water flows into the interior of the sprinkler head through a connecting pipe and a lifting pipe. When the water pressure is high, the water inside the sprinkler head pushes the lifting pipe to move upward, compressing the third spring so that the hole groove on the outer wall of the lifting pipe is connected to the second water outlet, so that the water flows out through the second water outlet; on the contrary, when the water pressure is low, the force of the third spring causes the lifting pipe to move to the bottom of the sprinkler head, thereby connecting with the first water outlet; since the aperture of the first water outlet is smaller than that of the second water outlet, the sprinkler head can automatically adjust the water outlet according to the water pressure to maintain the stability of the irrigation range.

[0028] (2) In the garden landscape maintenance water-saving irrigation device, when the external water supply is sufficient, the water pressure inside the three-way pipe and the driving force of the first spring work together to cause the valve cage to slide toward one end of the water tank until the end of the valve cage fits tightly with the limit ring, causing the compensation pipe to close. When the external water supply is insufficient or interrupted, the water pressure inside the three-way pipe drops, and the water pressure inside the water tank pushes the valve cage to compress the first spring, so that the end of the valve cage extends from the inside of the limit ring, opening the hole groove on the outer wall of the valve cage, allowing the water inside the water tank to flow into the three-way pipe, ensuring the stability of the water supply to the sprinkler head and reducing the impact of external water pressure fluctuations on the device.

[0029] (3) A garden landscape maintenance water-saving irrigation device, the top of the water tank of the device adopts an open design to facilitate the collection of rainwater; when rainwater flows in, it first contacts the guide plate, and the groove design on the surface of the guide plate helps to precipitate dust and impurities in the rainwater; the rainwater after precipitation is further filtered through the filter plate and finally gathers at the bottom of the guide plate; when the weight of rainwater at the bottom of the guide plate reaches a preset threshold, the bottom of the guide plate will flip over to guide the rainwater into the water tank; after the rainwater is emptied, the second spring resets the guide plate to keep the water storage space at the bottom of the water tank closed; this design not only realizes the effective collection of rainwater and saves water resources, but also reduces water loss by reducing the evaporation of water inside the water tank.

[0030] This solves the problem that the existing device is affected by water pressure fluctuations, which in turn leads to an unstable irrigation range of the sprinkler head of the device and a single water supply method. BRIEF DESCRIPTION OF THE DRAWINGS
