Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a solar-powered automatic irrigation device. Background Technology

[0002] With the continuous development of agricultural automation and energy-saving technologies, solar-powered automatic irrigation equipment has gradually gained widespread application due to its environmentally friendly and low-energy consumption characteristics. Publication CN114931082A discloses a solar-powered ecological agricultural water-saving irrigation device that is easy to operate and can effectively increase the irrigation range of sprinkler irrigation equipment.

[0003] First, solar panels in traditional equipment are mostly fixed in place, such as by directly fixing them to vertical water pipes or the surface of the equipment casing. Because the angle of sunlight varies over time, fixed solar panels cannot effectively receive direct sunlight most of the time, resulting in low energy conversion efficiency. This is especially true when the panels are in a vertical position, where the effective light-receiving area is significantly reduced, directly affecting the equipment's continuous power supply capacity and potentially causing irrigation interruptions due to insufficient energy storage.

[0004] Secondly, while some adjustable-angle solar irrigation devices improve sunlight reception through rotating structures, their designs are quite complex. For example, using independent brackets or motor-driven angle adjustment not only increases manufacturing costs but may also lead to structural instability with frequent adjustments. Especially during irrigation, the impact of water flow can easily cause rotating parts to loosen or shift, affecting the overall reliability of the equipment. Furthermore, complex adjustment mechanisms increase the difficulty of installation and maintenance, hindering users from quickly disassembling or replacing components.

[0005] Furthermore, existing equipment often relies on clips or fasteners to connect water pipes to external pipelines. This requires additional tools during installation and makes it difficult to guarantee a proper seal. Over time, leaks or loose connections can occur, impacting irrigation efficiency. To address these issues, an irrigation system with a simple structure, high stability, and the ability to adaptively adjust the angle of solar panels is needed. This system should improve solar energy utilization while also ensuring ease of installation and operational reliability. Utility Model Content

[0006] This utility model aims to solve the technical problems in existing solar irrigation equipment, such as low light energy conversion efficiency due to fixed orientation of solar panels, instability due to complex adjustable angle structures, and inconvenience in disassembling and assembling water pipes. It provides a solar-powered automatic irrigation device with adjustable function to adapt to sunlight and stable structure.

[0007] A solar-powered automatic irrigation device includes a fixed shell and a movable shell. The side of the fixed shell is rotatably connected to the side of the movable shell via a rotating joint. A water pipe runs vertically through the fixed shell, and a water valve is installed inside the water pipe. A solar panel is fixedly mounted on the outer surface of the movable shell. The water pipe of the irrigation device is installed between the faucet outlet and the outlet pipe. A controller is located inside the movable shell to control the opening and closing of the water valve. The entire device is designed to irrigate plants on a timed and metered basis. When the water valve is opened, water flows from the faucet through the water pipe to the outlet pipe to irrigate the plants; when the water valve is closed, irrigation stops. The fixed shell is used to fix the position of the water pipe to maintain its stability. The solar panel mounted on the movable shell is used to absorb sunlight to charge the internal controller. Because the main body of the pipe is installed on the faucet, it is vertically oriented. When the sides of the fixed shell and the movable shell are completely in contact, the solar panel is also in a completely vertical state, resulting in a small area exposed to sunlight and a small energy absorption and conversion rate. Therefore, the fixed shell and the movable shell are connected by a rotary joint. With the fixed shell in the same position, the movable shell is rotated to allow the solar panel to face the sun directly, increasing the irradiated area. The rotation angle of the movable shell is changed according to the movement of the sun at different times, increasing the proportion of light energy converted into electrical energy under the same conditions and extending the continuous working time of the equipment.

[0008] A solar-powered automatic irrigation device includes a fixed housing with a first positioning hole. A water pipe comprises a cylindrical pipe body, which is fixed within the first positioning hole. The first positioning hole is used to stabilize the pipe body. A cylindrical connecting sleeve is provided on the side of the fixed housing, and a water pipe connecting shaft extends horizontally from the side of the pipe, coaxially inserting into the connecting sleeve via a clearance fit.

[0009] A solar-powered automatic irrigation device includes a second positioning hole on the side of a movable housing. The outer cylindrical surface of a connecting sleeve rotates with the inner wall of the second positioning hole. The end of a water pipe connecting shaft extends into the second positioning hole. The connecting sleeve, the water pipe connecting shaft, and the second positioning hole have a coaxial structure, forming the rotational central axis of a rotating pair. The movable housing can rotate around the central axis of the rotating pair. A cylindrical rotating pin is provided at the end face of the water pipe connecting shaft, and a circular pin hole that mates with the rotating pin is provided on the inner end face of the second positioning hole. The rotating pin can rotate within the pin hole, and the water pipe connecting shaft also mates with the movable housing, allowing the movable housing to rotate around the central axis of the water pipe connecting shaft.

[0010] A solar-powered automatic irrigation device has a main pipe with an inlet at one end and an outlet at the other. The inlet has a standard threaded structure on its inner wall, and the outlet has a standard threaded structure on its outer wall. A faucet is threaded to the inlet, and a water pipe is threaded to the outlet. The inlet and outlet, along with the threads, facilitate the assembly and disassembly of the irrigation device.

[0011] A solar-powered automatic irrigation device includes a limiting pin on the side of a movable housing and a corresponding arc-shaped groove on the side of a fixed housing. The limiting pin is inserted into the arc-shaped groove, and the axis of the center of the arc-shaped groove coincides with the axis of the rotating joint. The limiting pin and the arc-shaped groove together limit the rotation angle of the movable housing, preventing the angle from being too large and affecting the stability of the entire device during irrigation, and preventing loosening and structural damage during irrigation. The arc angle α of the arc-shaped groove is between 30° and 70°.

[0012] The advantages of this invention are as follows: The rotating joint connection structure between the fixed and movable shells allows the solar panel to rotate flexibly with the sun's position, significantly improving light capture efficiency. Simultaneously, the coaxial design of the water pipe connecting shaft and the connecting sleeve simplifies the complex independent adjustment mechanism of traditional equipment, balancing manufacturing cost and operational stability. The combination of the limiting pin and the arc-shaped groove effectively prevents structural loosening caused by excessive angular deviation, ensuring overall reliability under water flow impact during irrigation. Furthermore, the standardized threaded interface design at both ends of the water pipe enables quick assembly and disassembly of the faucet and water outlet pipe, allowing for tool-free sealing connections and greatly improving installation and maintenance convenience.

Detailed Implementation

[0021] 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.

[0022] Example 1:

[0023] See attached document Figure 1 Appendix Figure 2 As shown, attached Figure 6 As shown, a solar-powered automatic irrigation device includes a fixed shell 2 and a movable shell 3. The side of the fixed shell 2 is rotatably connected to the side of the movable shell 3 via a rotating joint. A water pipe 1 runs vertically through the fixed shell 2, and a water valve 123 is installed inside the water pipe 1. A solar panel 4 is fixedly installed on the outer surface of the movable shell 3. The main pipe body 12 of the irrigation device is installed between the water outlet of a faucet 5 and the water outlet pipe 6. A controller is installed inside the movable shell 3 to control the opening and closing of the water valve 123. The entire device is designed to irrigate plants on a timed and metered basis. When the water valve 123 is opened, water flows from the faucet 5 through the water pipe 1 to the water outlet pipe 6 to irrigate the plants. When the water valve 123 is closed, irrigation stops. The fixed shell 2 is used to fix the position of the water pipe 1 to keep it stable, and the solar panel 4 installed on the movable shell 3 is used to absorb sunlight to charge the internal controller. Because water pipe 1 is installed on faucet 5 and is oriented vertically, with the sides of fixed shell 2 and movable shell 3 completely in contact, solar panel 4 is also in a completely vertical position. This results in a very small area receiving sunlight and a low energy conversion rate. Therefore, fixed shell 2 and movable shell 3 are connected by a rotary joint. With fixed shell 2 remaining in the same position, rotating movable shell 3 allows solar panel 4 to face the sun directly, increasing the irradiated area. The rotation angle of movable shell 3 is adjusted according to the sun's movement at different times, increasing the proportion of light energy converted into electrical energy under the same conditions and extending the device's continuous operating time.

[0024] See attached document Figure 2 Appendix Figure 3As shown, a solar-powered automatic irrigation device has a fixed housing 2 with a first positioning hole 22. The water pipe 1 includes a cylindrical pipe body 12, which is fixed in the first positioning hole 22. The first positioning hole 22 is used to fix the pipe body 12 to keep it stable.

[0025] See attached document Figure 2 As shown, attached Figure 3 As shown, a solar-powered automatic irrigation device has a cylindrical connecting sleeve 21 on the side of the fixed shell 2, and a water pipe 1 extends horizontally to form a water pipe connecting shaft 11. The water pipe connecting shaft 11 is coaxially inserted into the connecting sleeve 21 through a clearance fit.

[0026] See attached document Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, a solar-powered automatic irrigation device has a second positioning hole 31 on the side of a movable housing 3. The outer cylindrical surface of a connecting sleeve 21 forms a rotational fit with the inner wall of the second positioning hole 31. The end of a water pipe connecting shaft 11 extends into the second positioning hole 31. The connecting sleeve 21, the water pipe connecting shaft 11, and the second positioning hole 31 have a coaxial structure, forming the rotational central axis of a rotating pair. The movable housing 3 can rotate around the central axis of the rotating pair.

[0027] See attached document Figure 2 , attached Figure 4 As shown, a solar-powered automatic irrigation device has a cylindrical rotating pin 111 at the end face of the water pipe connecting shaft 11, and a circular pin hole 311 that mates with the rotating pin 111 on the inner end face of the second positioning hole 31. The rotating pin 111 can rotate within the pin hole 311, and the water pipe connecting shaft 11 also mates with the movable housing 3, which can rotate around the central axis of the water pipe connecting shaft 11.

[0028] See attached document Figure 2 As shown, a solar-powered automatic irrigation device has a pipe body 12 with an inlet 121 at one end and an outlet 122 at the other end. The inner wall of the inlet 121 is machined with a standard thread structure, and the outer wall of the outlet 122 is machined with a standard thread structure.

[0029] See attached document Figure 6 As shown, a solar-powered automatic irrigation device has a faucet 5 threadedly connected to an inlet 121 and an outlet pipe 6 threadedly connected to an outlet 122. The threads at the inlet 121 and outlet 122 facilitate the assembly and disassembly of the irrigation device.

[0030] See attached document Figure 5As shown, a solar-powered automatic irrigation device has a limiting pin 32 on the side of a movable shell 3, and an arc-shaped groove 23 on the corresponding position on the side of a fixed shell 2. The limiting pin 32 is inserted into the arc-shaped groove 23, and the axis of the center of the arc-shaped groove 23 coincides with the axis of the rotating joint. The limiting pin 32 and the arc-shaped groove 23 together limit the rotation angle of the movable shell 3, preventing the angle from being too large and affecting the stability of the entire device during irrigation, and preventing loosening and structural damage during irrigation. The arc angle α of the arc-shaped groove 23 is between 30° and 70°.
