Description

Technical Field

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

[0002] In the field of garden plant irrigation, traditional irrigation systems mainly rely on flood irrigation and ordinary sprinkler irrigation. Flood irrigation achieves irrigation by flooding large amounts of water. Although it is simple to operate, it requires a large amount of water and cannot control the local water volume. Ordinary sprinkler irrigation systems spray water through fixed nozzles. Although it improves irrigation efficiency, it still has problems such as uneven water distribution and poor terrain adaptability. Both types of systems rely on municipal water supply as the main water source, which is insufficient for the collection and utilization of natural precipitation. They also lack real-time monitoring and dynamic control of soil moisture, making it difficult to meet the needs of modern garden refined management.

[0003] The water infiltration loss rate under the above-mentioned flood irrigation method is as high as 60% or more. Ordinary sprinkler irrigation cannot accurately match the different water requirements of plants, resulting in 30%-40% of the water being wasted ineffectively. In addition, traditional systems are not designed with rainwater collection facilities, and a large amount of precipitation is directly runoffed and lost, failing to be converted into usable water. In view of this, this paper proposes a high-efficiency water-saving irrigation device suitable for garden plant irrigation. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency water-saving irrigation device suitable for irrigating garden plants, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency water-saving irrigation device suitable for irrigating garden plants includes several vertical pipes, several universal sprinklers, and several flow regulating valves. The water inlets of several universal sprinklers are vertically connected to the top of several vertical pipes through the flow regulating valves. The water inlets at the lower ends of several vertical pipes are all fixedly connected to a first pipe. The first ends of several first pipes are connected to a water collection tank.

The lower end of the inner cavity of the conical water collection body is fixedly connected to a second pipe. The outlet of the second pipe is connected to the inner cavity at the top of the water collection tank. A soil moisture sensor is fixedly connected to one side of the conical water collection body. The soil moisture sensor is electrically connected to the nearest flow regulating valve.

[0008] Preferably, a positioning column is fixedly connected to the top of the conical water collector, and a connecting pipe protrudes from the lower part of the inner cavity of the conical water collector, with the outer wall of the positioning column and the inner wall of the connecting pipe fitting together.

The outer conical cylinder has densely arranged external seepage holes around its inner cavity, and the inner diameter of the external seepage holes is larger than the inner diameter of the internal seepage holes.

[0010] Preferably, the inlet of the rainwater pump is fixedly connected to the outlet at the lower end of the water collection tank, the outlet of the rainwater pump is fixedly connected to a pressure storage tank, and the outlet of the pressure storage tank is fixedly connected to the inlet at the beginning of the first pipe.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-2 As shown, a high-efficiency water-saving irrigation device suitable for irrigating garden plants includes several vertical pipes 5, several universal sprinklers 6, and several flow regulating valves. The universal sprinklers 6 are set above the garden ground and can adjust the spray direction according to actual needs to cover garden plants in different areas. The water inlets of the several universal sprinklers 6 are vertically connected to the top of the several vertical pipes 5 through the flow regulating valves. The flow regulating valves can be common electric flow regulating valves, such as electric ball valves with models DN15 and DN200, which can accurately adjust the water flow according to the received signal.

[0025] like Figure 1 As shown, the inlets at the lower ends of several vertical pipes 5 are all fixedly connected to the first pipe 4, and the first ends of several first pipes 4 are connected to the water collection trough 1. The water collection trough 1 is set below the garden ground and serves to collect and store rainwater. The water collection trough 1 can be made of reinforced concrete or plastic material, and its capacity can be designed according to the garden area and local rainfall.

[0026] It should be noted that this application requires regular checks on the water level and water quality in the water collection tank 1, timely cleaning of debris and sediment in the water collection tank 1 to ensure the normal use of the water collection tank 1. It also requires regular checks on the working status of equipment such as rainwater pump 2, flow regulating valve and soil moisture sensor 806. If there is any malfunction, it should be repaired or replaced in time.

[0027] like Figure 1 As shown, a rainwater pump 2 is connected between the water collection tank 1 and the first pipe 4. The rainwater pump 2 is mainly used to draw water from the inner cavity of the water collection tank 1 and deliver it to the first pipe 4 and the universal sprinkler head 6 above. The rainwater pump 2 can be a single-stage single-suction pipeline centrifugal pump of the ISG series. This type of pump has the characteristics of high efficiency, energy saving and stability, and can meet the water delivery needs of the irrigation device.

[0028] like Figure 1As shown, the inlet of the rainwater pump 2 is fixedly connected to the outlet at the lower end of the water collection tank 1. The outlet of the rainwater pump 2 is fixedly connected to the pressure storage tank 3. The pressure storage tank 3 can be a diaphragm pressure tank, such as the SQL series pressure tank. The function of the pressure storage tank 3 is to stabilize the water pressure of the irrigation system and ensure that the water output from the sprinkler head is uniform. The outlet of the pressure storage tank 3 is fixedly connected to the inlet at the beginning of the first pipe 4.

[0029] like Figure 1 and Figure 2 As shown, a water collection component 8 is installed below the ground on one side of the vertical pipe 5. The water collection component 8 includes three conical water collection bodies 801 connected sequentially from top to bottom. The inner diameter of the conical water collection bodies 801 gradually decreases from bottom to top. This structural design is conducive to the convergence and collection of rainwater.

[0030] like Figure 2 As shown, a positioning post 807 is fixedly connected to the top of the conical water collection body 801. A connecting pipe 802 protrudes from the lower part of the inner cavity of the conical water collection body 801. The outer wall of the positioning post 807 and the inner wall of the connecting pipe 802 fit together. The positioning posts 807 at the top of the two lower conical water collection bodies 801 are respectively fitted into the connecting pipes 802 at the lower end of the inner cavity of the two upper conical water collection bodies 801. Through this fitting method, the stable connection and sealing performance between the three conical water collection bodies 801 are ensured.

[0031] It should be added that when installing the water collection component 8, it is necessary to ensure that the positioning post 807 and the connecting pipe 802 between the three conical water collection bodies 801 are accurately fitted, and to use bolts 809 and nuts 810 to tighten them to ensure the stability and sealing of the connection.

[0032] like Figure 1 As shown, the lower end of the inner cavity of the conical water collection body 801 is fixedly connected to a second pipe 7. The outlet of the second pipe 7 is connected to the inner cavity of the top of the water collection tank 1, which is used to transport the rainwater collected by the water collection component 8 to the water collection tank 1.

[0033] like Figure 2 As shown, the inner cavity of the conical water collection body 801 is densely surrounded by internal infiltration holes 803. The inner cavity size of the internal infiltration holes 803 is smaller than the size of the filter sand particles, which can prevent the filter sand from entering the interior of the conical water collection body 801. The outer cone 804 is coaxially arranged around the outer cavity of the conical water collection body 801. The inner cavity of the outer cone 804 is densely surrounded by external infiltration holes 805. The inner diameter of the external infiltration holes 805 is larger than the inner diameter of the internal infiltration holes 803. This design allows rainwater to first enter the filter sand layer between the outer cone 804 and the conical water collection body 801 through the external infiltration holes 805, and after filtration, enter the interior of the conical water collection body 801 through the internal infiltration holes 803.

[0034] Furthermore, the space between the outer cone 804 and the outer wall of the cone-shaped water collection body 801 is filled with filter sand. This filter sand is used to prevent soil particles from entering the cone-shaped water collection body 801. The filter sand can be made of quartz sand, and its particle size can be selected according to the actual situation, generally between 13 mm.

[0035] like Figure 2 As shown, several connecting ears 808 are fixedly connected to the periphery of the conical water collection body 801. Several bolts 809 are connected between the several connecting ears 808 on the periphery of the three conical water collection bodies 801. Nuts 810 are threaded to the top of the bolts 809. The bolts 809 pass through the connecting ears 808. Through the fastening action of the bolts 809 and nuts 810, the connection stability between the three conical water collection bodies 801 is further enhanced.

[0036] like Figure 2 As shown, a soil moisture sensor 806 is fixedly connected to one side of the conical water collection body 801. The soil moisture sensor 806 should be installed in a suitable position around the vertical pipe 5 to ensure accurate detection of the soil moisture around the vertical pipe 5. The soil moisture sensor 806 can be a soil moisture sensor 806 with model number SM01. This soil moisture sensor 806 has the characteristics of high precision and good stability, and can monitor the soil moisture in real time and accurately.

[0037] To further explain, the soil moisture sensor 806 is electrically connected to the nearest flow regulating valve. When the soil moisture sensor 806 detects that the soil moisture around the riser 5 is lower than the set value, it will transmit a signal to the flow regulating valve. The flow regulating valve will automatically open or increase its opening based on the received signal, allowing more water to be sprayed around the garden plants through the universal sprinkler head 6. When the soil moisture reaches the set value, the soil moisture sensor 806 sends a signal to the flow regulating valve, and the flow regulating valve will automatically close or decrease its opening, thereby achieving precise irrigation and water conservation.

[0038] In this embodiment, when it rains, rainwater enters the filter sand layer between the outer cone 804 and the cone-shaped water collection body 801 through the external infiltration hole 805 on the outer cone 804. After being filtered by the filter sand and removing impurities such as soil particles, the rainwater enters the interior of the cone-shaped water collection body 801 through the internal infiltration hole 803. Then, the rainwater flows into the water collection tank 1 through the second pipe 7 for storage.

[0039] When the soil moisture sensor 806 detects that the soil moisture around the riser pipe 5 is lower than the set value, it transmits a signal to the nearest flow regulating valve. At the same time, the rainwater pump 2 is started. The rainwater pump 2 draws rainwater from the collection tank 1 and delivers it to the pressure storage tank 3 for pressure stabilization. The pressure-stabilized water flows through the first pipe 4 and the riser pipe 5, and after the flow regulating valve adjusts the flow rate, it is sprayed from the universal sprinkler head 6 to the area around the garden plants. When the soil moisture reaches the set value, the soil moisture sensor 806 sends a signal to the flow regulating valve, which closes or reduces its opening. At the same time, the rainwater pump 2 stops working, and the irrigation process ends.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
