Description

Technical Field

[0001] This application relates to the field of sprinkler irrigation technology, and more particularly to a pointer-type sprinkler irrigation device. Background Technology

[0002] Sprinkler irrigation systems are commonly used in agricultural irrigation, widely applied in large-scale farmlands, grasslands, and parks. By converting water flow into a mist and spraying it evenly onto the soil surface, sprinkler irrigation effectively conserves water resources and promotes crop growth. As modern agriculture increasingly demands higher irrigation efficiency and more refined management, the design of sprinkler irrigation systems continues to evolve to adapt to different terrains and irrigation needs.

[0003] Existing sprinkler irrigation systems typically adjust the spray range by rotating the sprinkler head or a rotating structure. Traditional spray range adjustment methods generally rely on the rotation of the equipment, changing the direction of the sprinkler head or the spray angle to achieve coverage of the sprayed area. Although this rotation mechanism can provide a certain degree of spray range, it has certain limitations because the adjustment of the spray range depends solely on rotation, and cannot fully meet the needs of complex terrain or the requirement for precise irrigation.

[0004] Therefore, how to effectively expand the spraying range and provide more flexible spraying adjustment capabilities has become a key issue in current technology. Utility Model Content

[0005] This application provides a pointer-type sprinkler irrigation device to solve the limitation of the prior art where the spray range adjustment relies solely on rotation.

[0006] This application provides a pointer-type sprinkler irrigation device, including a rotating mounting frame and a sprinkler irrigation mechanism mounted on the rotating mounting frame and pointing in a pointer-like manner. The sprinkler irrigation mechanism includes a water receiving assembly, a main water pipe, an airflow regulating pipe, an air source input pipe, a water spray pipe, and a distribution pipe.

[0007] The water receiving assembly includes a water receiving pipe for connecting to a water source. The water receiving pipe is vertically connected to the main water pipe. One end of the main water pipe is provided with a distribution pipe for connecting to the spray pipe. The other end of the main water pipe is fixedly connected to the air source input pipe. The distribution pipe is provided with multiple distribution connectors for connecting to the spray pipe. The water receiving pipe is connected to the airflow regulating pipe and connected to the air source input pipe through the airflow regulating pipe. The airflow regulating pipe is provided with a valve for regulating the airflow. The air source input pipe is provided with the rotating mounting bracket.

[0008] As an alternative embodiment of this application, the free end of the water inlet pipe is provided with a connector for connecting to a water source.

[0009] As an alternative embodiment of this application, the rotating mounting bracket is connected to a connecting column that is perpendicular to the gas source input pipe, and the rotating mounting bracket is fixedly connected to a rotating disk through the connecting column.

[0010] As an alternative embodiment of this application, one end of the connecting post is connected to a non-center position on the surface of the rotating disk.

[0011] As an optional embodiment of this application, the number of water inlet pipes is two, and each of the two water inlet pipes is connected to an airflow regulating pipe. The two water inlet pipes are spaced 180° apart on both sides of the main water pipe and are symmetrically distributed.

[0012] As an optional embodiment of this application, the water receiving assembly further includes an annular water supply pipe. Two symmetrically distributed connectors spaced 180° apart are provided on one side of the inner annular surface of the annular water supply pipe. The connector is a bidirectional threaded connector. One end of the connector is threadedly connected to the water receiving pipe, and the other end of the connector is threadedly connected to the connector. The annular water supply pipe is also provided with a water receiving end, which is connected to a hose to access a water source.

[0013] As an alternative embodiment of this application, the annular water supply pipe is connected to a water supply pipe support, and the annular water supply pipe is connected to the two water receiving pipes through the water supply pipe support.

[0014] As an optional embodiment of this application, the water spray pipe is a spray pipe with an atomizing nozzle, a bearing is installed at the center of the rotating disk and a rotating rod is connected to the bearing, and the water spray pipe can change the spraying direction as the rotating disk rotates.

[0015] As an alternative to this application, the valve is a knob valve or a solenoid valve.

[0016] As an alternative embodiment of this application, the water inlet pipe adopts an hourglass-shaped connecting pipe structure with a smaller middle and larger ends at the connection point with the airflow regulating pipe.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] 1. The pointer-type sprinkler irrigation device provided in this application adopts a structure in which the sprinkler mechanism is mounted on a rotating mounting frame. The sprinkler mechanism points in a pointer manner on the rotating mounting frame, facilitating targeted irrigation. The rotating mounting frame provides stable support for the sprinkler mechanism, and the sprinkler pipe of the sprinkler mechanism can rotate and spray at different angles under the action of the rotating mounting frame. This expands the spray range as the rotation angle changes, avoiding the limitation of the spray range due to a fixed spray pipe direction. In addition, this application sets an airflow regulating pipe between the air source input pipe and the water inlet pipe, and sets a valve on the airflow regulating pipe to adjust the airflow. By combining the use of the airflow regulating pipe and the valve, the spray range can be further affected by adjusting the airflow. When the airflow increases, the spray becomes finer and the coverage area increases; conversely, when the airflow decreases, the sprayed water flow becomes more concentrated, and the spray range decreases accordingly. This spray range adjustment based on airflow regulation makes this application more flexible and adaptable than traditional devices, able to meet different terrains and irrigation needs, and improve sprinkler irrigation efficiency.

[0019] 2. This application achieves precise regulation of airflow by setting up an airflow regulating pipe and valve. The valve can control the proportion of airflow entering the water flow, thereby optimizing the mixing effect of water and air. By adjusting the airflow, the spray pipe can adjust the atomization effect according to the change in airflow, making the sprayed water mist more uniform and fine. This airflow regulation method not only improves the atomization effect of the water flow, but also enhances the uniformity of spraying, avoiding the problems of uneven spraying and water waste caused by unsuitable airflow and water flow ratio in traditional devices.

[0020] 3. The main water pipe of this application is equipped with a distribution pipe and multiple distribution joints, which can be used to connect multiple sprinkler pipes. This design allows water to be evenly distributed from the main water pipe to each sprinkler pipe. The distribution pipe guides the water flow precisely to each sprinkler pipe through multiple distribution joints, thereby ensuring that each sprinkler pipe receives an appropriate amount of water, avoiding uneven water flow, improving irrigation efficiency. At the same time, in conjunction with airflow regulation, water resources are used more efficiently, especially in arid or water-limited areas, where water-saving effects can be fully demonstrated.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0028] Please see Figures 1-3 This application provides a pointer-type sprinkler irrigation device, including a rotating mounting frame 700 and a sprinkler mechanism mounted on the rotating mounting frame 700 and pointing in a pointer-like manner. The sprinkler mechanism includes a water receiving assembly 100, a main water pipe 200, an airflow regulating pipe 300, an air source input pipe 400, a water spray pipe 500, and a distribution pipe 600.

[0029] The water receiving assembly 100 includes a water receiving pipe 110 for connecting to a water source. The water receiving pipe 110 is vertically connected to the main water pipe 200. One end of the main water pipe 200 is provided with a distribution pipe 600 for connecting to a spray pipe 500. The other end of the main water pipe 200 is fixedly connected to an air source input pipe 400 for connecting to an air source. The distribution pipe 600 is provided with multiple distribution connectors 610 for connecting to the spray pipe 500. An airflow regulating pipe 300 is connected to the water receiving pipe 110 and is connected to the air source input pipe 400. The airflow regulating pipe 300 is provided with a valve 310 for regulating the airflow. A rotating mounting bracket 700 is provided on the air source input pipe 400.

[0030] The pointer-type sprinkler irrigation device provided in this application adopts a structure in which the sprinkler mechanism is mounted on a rotating mounting frame 700. The sprinkler mechanism points in a pointer manner on the rotating mounting frame 700, facilitating targeted irrigation. The rotating mounting frame 700 provides stable support for the sprinkler mechanism, and the water spray pipe 500 of the sprinkler mechanism can rotate and spray at different angles under the action of the rotating mounting frame 700. This expands the spray range as the rotation angle changes, avoiding the limitation of the spray range due to the fixed direction of the water spray pipe 500. In addition, this application sets an airflow regulating pipe 300 between the air source input pipe 400 and the water inlet pipe 110, and sets a valve 310 on the airflow regulating pipe 300 to regulate the airflow. By combining the use of the airflow regulating pipe 300 and the valve 310, the spray range can be further affected by adjusting the airflow. When the airflow increases, the spray becomes finer and the coverage area increases; conversely, when the airflow decreases, the sprayed water flow becomes more concentrated, and the spray range decreases accordingly. This application's spray range adjustment based on airflow regulation makes it more flexible and adaptable than traditional devices, enabling it to meet different terrains and irrigation needs and improve sprinkler irrigation efficiency.

[0031] Meanwhile, by setting up an airflow regulating pipe 300 and a valve 310, this embodiment of the application can achieve more precise regulation of airflow. The valve 310 can control the proportion of airflow entering the water flow, thereby optimizing the mixing effect of water flow and airflow. By adjusting the airflow, the spray pipe 500 can adjust the atomization effect according to the change of airflow, making the sprayed water mist more uniform and fine. This airflow regulation method can not only improve the atomization effect of water flow, but also improve the uniformity of spraying, avoiding the problems of uneven spraying and water waste caused by unsuitable airflow and water flow ratio in traditional devices.

[0032] Furthermore, the main water pipe 200 of this application is equipped with a distribution pipe 600 and multiple distribution connectors 610 on the distribution pipe 600, which can be used to connect multiple sprinkler pipes 500. This design allows the water flow to be evenly distributed from the main water pipe 200 to each sprinkler pipe 500. The distribution pipe 600 guides the water flow precisely to each sprinkler pipe 500 through multiple distribution connectors 610, thereby ensuring that each sprinkler pipe 500 receives an appropriate amount of water, avoiding uneven water flow, and improving irrigation efficiency. At the same time, in conjunction with the airflow regulating pipe 300 and the valve 310, water resources are used more efficiently, especially in arid or water-limited areas, where water-saving effects can be fully demonstrated.

[0033] In using the pointer-type sprinkler irrigation device of this application embodiment, the air source input pipe 400 is connected to an air source system suitable for sprinkler irrigation needs. Specifically, the air source input pipe 400 can be connected to several common air sources to adapt to different irrigation needs and working environments:

[0034] Compressed air source: Compressed air is the most commonly used air source in most agricultural irrigation applications. By connecting to a compressed air system, the air source input pipe 400 can provide sufficient airflow pressure to regulate water flow and achieve a mixing and atomization effect of airflow and water flow. Compressed air can be provided by a compressor, ensuring a stable supply of airflow, which is especially suitable for large-area irrigation scenarios such as farmland and orchards.

[0035] Gas cylinders (such as carbon dioxide or nitrogen cylinders): In certain irrigation environments, such as relatively enclosed spaces or areas with limited gas supply, gas cylinders can be used as a gas source. Gas cylinders can store sufficient gas to provide a certain pressure and flow rate, making them suitable for small-scale, precision irrigation applications, especially in urban horticulture and greenhouse cultivation.

[0036] Compressed air supply systems (such as air pumps): For applications with lower irrigation requirements, such as home gardens and greenhouses, compressed air pumps can serve as an air source to provide airflow. This type of air supply system is generally economical and energy-efficient, suitable for applications requiring low airflow and small-area spraying.

[0037] In some embodiments, the free end of the water inlet pipe 110 is provided with a connector 111 for connecting to a water source.

[0038] In the above embodiments, the connector 111 makes the connection between the water pipe 110 and the water source more stable and allows for quick connection and disconnection, facilitating user connection operations according to actual needs. Especially when the water source needs to be replaced or maintenance is required, the connector 111 greatly improves the convenience and flexibility of the connection. Moreover, this design not only improves the efficiency of water source access but also simplifies the maintenance of the entire sprinkler irrigation system.

[0039] In some embodiments, such as Figure 1 and Figure 3 As shown, the rotating mounting bracket 700 is connected to a connecting column 710 that is perpendicular to the air source input pipe 400, and the rotating mounting bracket 700 is fixedly connected to the rotating disk 720 through the connecting column 710.

[0040] In the above embodiment, a rotating mounting bracket 700 for installing the air source input pipe 400 is connected to a connecting column 710. The rotating mounting bracket 700 is fixedly connected to a rotating disk 720 via the connecting column 710. This design allows the irrigation mechanism to be connected to the rotating disk 720 via the rotating mounting bracket 700 and the connecting column 710, providing relatively stable support for the installation of the irrigation mechanism. Furthermore, the rotating disk 720 facilitates the installation of the entire device; during installation, it is only necessary to ensure that the rotating disk 720 is stably installed and can be manually rotated. During use, the reaction force generated by the water spray from the spray pipe 500 acts on the rotating disk 720, thereby driving the rotation of the rotating disk 720 without the need for additional driving devices such as motors. The rotation of the rotating disk 720 drives the rotation of the entire irrigation mechanism, thereby expanding the irrigation range. Furthermore, this embodiment combines the rotating disk 720 and the rotating mounting bracket 700 to install the sprinkler irrigation mechanism, ensuring its stability and good rotational performance, and preventing the sprinkler pipe 500 from swaying or becoming unstable during rotation. In addition, the rotating disk enables the sprinkler pipe 500 to change direction. Through this structural design, the spraying direction can be continuously changed during irrigation, better adapting to different irrigation needs.

[0041] In some embodiments, one end of the connecting post 710 is connected to a non-center position on the surface of the rotating disk 720.

[0042] In the above embodiment, one end of the connecting post 710 is connected to a non-central position on the surface of the rotating disk 720. This design differs from the traditional center-connection method of a turntable. In this embodiment, the connection position of the connecting post 710 is offset from the center of the rotating disk 720, making the rotating disk 720 more flexible during rotation. Moreover, by connecting one end of the connecting post 710 to a non-central position on the surface of the rotating disk 720, an asymmetrical torque can be generated. This design can effectively reduce the excessive weight distribution at the center position during rotation, preventing the rotating disk from relying too much on the stability of the center point. Furthermore, this asymmetrical torque can also benefit the driving rotation of the rotating disk 720, optimizing energy utilization efficiency. Since one end of the connecting post 710 is connected to a non-central position on the surface of the rotating disk 720, this eccentric design of the connection position means that the inertial force generated during rotation no longer completely depends on the power input at the center point. Instead, by adjusting the eccentric torque, energy loss during rotation is reduced.

[0043] In some embodiments, there are two water inlet pipes 110, and each of the two water inlet pipes 110 is connected to an airflow regulating pipe 300. The two water inlet pipes 110 are spaced 180° apart on both sides of the main water pipe 200 and are symmetrically distributed.

[0044] In the above embodiment, two water inlet pipes 110 are provided, and each of these two water inlet pipes 110 is connected to an airflow regulating pipe 300. The two water inlet pipes 110 are symmetrically distributed at a 180° interval on both sides of the main water pipe 200. This design makes the water flow introduction more uniform. Moreover, since the two water inlet pipes 110 are connected to the airflow regulating pipes 300 respectively, the airflow can be regulated and enter the two water inlet pipes 110. Through the mixing of the airflow in the airflow regulating pipes and the water flow in the water inlet pipes 110, the airflow and water flow form a more thorough contact. This causes the water flow in the two water inlet pipes 110 to form a countercurrent effect at the main water pipe 200. This countercurrent effect makes the mixing efficiency of the airflow and water flow higher, so that the airflow can be evenly mixed with the water flow before entering the main water pipe 200. This mixing effect provides a more uniform and fine water mist for subsequent atomized spraying, thereby improving the spray coverage and the uniformity of water flow distribution. Furthermore, when the water flow from the two water inlet pipes 110 is acted upon by the airflow in the airflow regulating pipe 300, and forms a countercurrent in the main water pipe 200, the two opposing water flows collide with each other, resulting in pressure concentration. This generates a higher flow velocity at the collision point, which can produce a higher jet pressure at the moment of spraying, thereby enhancing the power of the water spray. Especially when the water flow enters the water spray pipe 500, it can effectively enhance the jet pressure of the water flow, thereby increasing the spray range and obtaining a longer range.

[0045] In some embodiments, such as Figure 3 As shown, the water receiving assembly 100 also includes an annular water supply pipe 120. Two symmetrically distributed interface ports 121 spaced 180° apart are provided on one side of the inner annular surface of the annular water supply pipe 120. The connector 111 is a bidirectional threaded connector. One end of the connector 111 is threadedly connected to the water receiving pipe 110, and the other end of the connector 111 is threadedly connected to the interface port 121. The annular water supply pipe 120 is also provided with a water receiving end 122, which is connected to a water source by a hose.

[0046] In the above embodiment, the water receiving assembly 100 further includes an annular water supply pipe 120. The annular water supply pipe 120 has a water receiving end 122 and two symmetrically distributed connectors 121 spaced 180° apart on one side of its inner annular surface. The water receiving end 122 connects to a flexible hose to access a water source, making water access more flexible. The flexible hose connection not only facilitates connection between the device and the water source but also increases the convenience and adaptability during installation. Furthermore, the distribution function of the annular water supply pipe 120 ensures that the water flow is evenly distributed to the two water receiving pipes 110, maintaining consistency and balance in water flow distribution. Additionally, the connector 111 is a bidirectional threaded connector, with both ends threaded to the water receiving pipe 110 and the connector 121 respectively, making installation and disassembly simpler and more convenient. During use, the annular water supply pipe 120, through its connection to the water receiving pipe 110, allows water to be quickly distributed to the two water receiving pipes 110. Furthermore, in this embodiment, by setting up an annular water supply pipe 120, a single water source can be connected to and supply the entire water receiving assembly 100 through the water receiving end 122, without each water receiving pipe 110 needing to be directly connected to a water source. The annular water supply pipe 120 acts as a central distribution pipe, and through the interface 121 set on one side of the inner ring surface, the water source can be distributed within the annular water supply pipe and evenly distributed to the water receiving pipes 110 on both sides through two symmetrically distributed joints 111.

[0047] This design in the above embodiment simplifies the complexity of water source connection. Water can be supplied to the entire sprinkler irrigation system simply by connecting a hose to the inlet 122 of the annular water supply pipe 120. This method not only simplifies the connection process but also reduces installation costs and ensures a stable water supply.

[0048] In some embodiments, a water supply pipe support 123 is connected to the annular water supply pipe 120, and the annular water supply pipe 120 is connected to two water inlet pipes 110 through the water supply pipe support 123.

[0049] In this embodiment, the annular water supply pipe 120 is connected to two receiving pipes 110 via a water supply pipe bracket 123. This design uses the water supply pipe bracket 123 as a support structure connecting the annular water supply pipe 120 and the receiving pipes 110, enhancing the stability of the connection. The water supply pipe bracket 123 firmly fixes the annular water supply pipe 120 to the receiving pipes 110, avoiding loosening or joint breakage problems that may be caused by vibrations generated when water flows through the pipe. The support provided by the bracket ensures that the pipe maintains a stable connection during long-term use, enhancing durability and extending the service life of the sprinkler irrigation device.

[0050] In some embodiments, the water spray pipe 500 is a spray pipe with an atomizing nozzle, and a bearing is installed at the center of the rotating disk 720 and a rotating rod 721 is connected to the bearing. The water spray pipe 500 can change the spraying direction as the rotating disk 720 rotates.

[0051] In the above embodiment, the water spray pipe 500 is a spray pipe with an atomizing nozzle, and a bearing is installed at the center of the rotating disk 720, which is connected to a rotating rod. During use, the water spray pipe 500 can change its spray direction as the rotating disk 720 rotates. This design not only provides an atomization effect but also allows the spray direction to continuously change according to the rotation of the rotating disk, achieving a wider spray range. The bearing installed at the center of the rotating disk 720, connected to the rotating rod, reduces resistance during rotation, ensuring smooth rotation and minimizing friction and wear during prolonged rotation. The bearing ensures smooth operation of the rotating disk over extended periods, reducing the likelihood of jamming or damage, thus improving the stability and durability of the device. During use, the rotating disk 720 and bearings should be inspected regularly to ensure smooth rotation. The bearings should be cleaned and lubricated as needed to prevent wear from affecting device performance.

[0052] In some embodiments, valve 310 is a knob valve or a solenoid valve.

[0053] In this embodiment, valve 310 is either a knob valve or a solenoid valve. A knob valve allows for manual adjustment of the airflow, while a solenoid valve enables automatic control. In practical applications, the appropriate valve 310 can be selected based on irrigation needs and the degree of automation to adjust the airflow, thereby optimizing the airflow and spraying effect of the irrigation system. By controlling the airflow, an optimal ratio of water and airflow can be achieved, improving the uniformity and coverage of the spraying effect. During use, valve 310 should be checked regularly to ensure it is functioning properly, especially since it is a solenoid valve, which must accurately respond to electrical signals to adjust the airflow. If any malfunction is found, it should be adjusted or replaced promptly.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the water inlet pipe 110 adopts an hourglass-shaped connecting pipe structure with a smaller middle and larger ends at the connection position with the airflow regulating pipe 300.

[0055] In this embodiment, the water inlet pipe 110 adopts an hourglass-shaped connecting pipe structure with a smaller middle and larger ends at the connection position with the airflow regulating pipe 300. This hourglass-shaped connecting pipe structure allows the airflow to have a better guiding effect when entering the water inlet pipe, thereby enhancing the mixing effect of water flow and airflow, improving the atomization effect during the sprinkler irrigation process, making the sprayed water mist more uniform and delicate, thereby improving the sprinkler irrigation effect and reducing water waste.

[0056] The usage process of the pointer-type sprinkler irrigation device provided in this application embodiment is as follows:

[0057] 1. Equipment installation

[0058] First, install the rotating mounting bracket 700 in the predetermined position, ensuring its stability. Next, install the sprinkler mechanism onto the rotating mounting bracket 700, enabling it to spray directionally as the bracket rotates. Connect the water inlet pipe 110 to the annular water supply pipe 120 via connector 111. The annular water supply pipe 120 is connected to a water source via a flexible hose, ensuring the sprinkler mechanism can properly connect to a water source. Then, connect the air source inlet pipe 400 to the air source.

[0059] 2. Equipment commissioning

[0060] The air flow rate in the airflow regulating pipe 300 is controlled by adjusting valve 310. The air flow rate is adjusted according to irrigation needs to achieve the optimal ratio of air to water, thus optimizing the spraying effect. The rotational flexibility of the rotating disc 720 is checked to prevent obstruction that could affect the irrigation effect.

[0061] 3. Sprinkler irrigation operation

[0062] With the water and air sources turned on, water flows through the ring-shaped water supply pipe 120 into two receiving pipes 110, then converges through the main water pipe 200 and enters the distribution pipe 600. From there, it is evenly distributed to each spray pipe 500 through multiple distribution connectors 610, ensuring a stable water flow to each spray pipe 500. During use, the airflow rate can be adjusted by changing the valve on the airflow regulating pipe 300, allowing for flexible control of the spraying range. Observe the spraying effect and assess soil moisture levels during use. Based on the observations, adjust the airflow and water flow ratio as needed to ensure uniform spraying without waste.

[0063] 4. Equipment maintenance

[0064] Regularly inspect the sprinkler system and all connections to ensure there are no leaks, blockages, or damage. If any problems are found, perform maintenance promptly to ensure the proper functioning of the sprinkler system.

[0065] In summary, the pointer-type sprinkler irrigation device of this application, through reasonable pipeline layout, airflow regulation and rotating structure design, can flexibly adjust the spraying range and atomization effect according to different irrigation needs.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
