[0047] Example 1

[0048] As Figure 1As shown, a dual-mode intelligent water valve with a clutch structure 2 includes a valve assembly 1 and an electrical control assembly 3. The valve assembly 1 includes a gate 11 and a lifting screw 12 connected to the gate 11. By rotating the lifting screw 12, the gate 11 moves up and down, thereby opening and closing the water valve. The upper end of the lifting screw 12 is connected to the clutch structure 2, which includes a main shaft 21, a clutch fork 22, and a manual component 23. The main shaft 21 is connected to the top of the lifting screw 12. The middle part of the main shaft 21 has a first groove 211 that mates with the clutch fork 22, and the bottom of the main shaft 21 has a first bevel tooth 24. The manual component 23 has a second bevel tooth 25 that meshes with the first bevel tooth 24. By rotating the clutch fork 22, the relative positions of the first bevel tooth 24 and the second bevel tooth 25 are changed, realizing the function of easily switching between manual and electric control modes. The switching between the two modes is simple and quick, improving the convenience of using the water valve.

[0049] Specifically, the clutch structure 2 has a first position and a second position, such as Figure 2 As shown, in the first position, rotating and lifting the operating handle 222 presses the clutch plate 221, causing the main shaft 21 to move downward axially until the first bevel gear 24 and the second bevel gear 25 mesh. By rotating the handwheel 27, the handwheel 27 drives the second bevel gear 25 to rotate via the connecting rod 26. Power is transmitted through the meshing of the second bevel gear 25 and the first bevel gear 24. The first bevel gear 24 drives the main shaft 21 to rotate, which in turn drives the lifting screw 12 to rotate, ultimately causing the gate 11 to move up and down, thus achieving manual control of the valve. Figure 3 As shown, in the second position, rotating and pressing the operating handle 222 can lift the clutch plate 221, causing the main shaft 21 to move upward axially. The first bevel tooth 24 and the second bevel tooth 25 at the lower end of the main shaft 21 separate. The main shaft 21 moves until the upper end of the main shaft 21 contacts the coupling structure 32 of the drive motor 31. The drive motor 31 drives the main shaft 21 to rotate through the coupling structure 32. The main shaft 21 drives the lifting screw 12 to rotate, thereby driving the gate 11 to move up and down, realizing the electric control of the valve.

[0050] like Figure 4 As shown, the main shaft 21 has a first groove 211 in the middle that cooperates with the clutch fork 22. The clutch fork 22 consists of a clutch plate 221 that cooperates with the first groove 211 of the main shaft 21 and an operating handle 222 for adjusting the position of the clutch plate 221. By rotating the operating handle 222, the clutch plate 221 can slide smoothly in the first groove 211 of the main shaft 21, thereby changing the position of the main shaft 21 and reducing wear and jamming. The surface of the operating handle 222 has anti-slip textures to facilitate the operator to apply force.

[0051] like Figure 5As shown, the clutch structure 2 is provided with a first fixed support 281 and a second fixed support 282 to enhance its structural strength and stability. The rotating shaft 223 in the middle of the clutch yoke 22 is connected with the first fixed support 281, so that the clutch yoke 22 can rotate flexibly and stably around the shaft. The connecting rod 26 is connected with the second fixed support 282 through the second bearing seat 261, which can bear radial and axial loads at the same time, effectively ensuring the stability of the connecting rod 26 during rotation, and ensuring the smoothness and reliability of manual operation. The first fixed support 281 and the second fixed support 282 are connected with the top of the valve fixed support 14 to prevent loosening of the fixed support due to vibration and other factors during water valve operation. The lifting screw 12 is connected with the valve fixed support 14 through the first bearing seat 141, ensuring that the lifting screw 12 can move smoothly up and down along the axial direction, and can effectively bear a certain degree of radial and axial loads generated under working conditions such as water flow impact and valve opening and closing, thereby ensuring the stable operation of the valve assembly 1 in complex working environments.

[0052] As shown in Figure 6 , the drive motor 31 is installed on the motor fixed support 34, and the drive motor 31 is connected with the top of the main shaft 21 through the shaft coupling structure 32, ensuring that the drive motor 31 can stably drive the main shaft 21 to rotate. One end of the sensor is connected with the gate 11 through the connecting plate 19, which can accurately monitor the working state of the water valve; the other end is connected with the sensor control part, and then the sensor control part is fixed on the motor fixed support 34, ensuring its stable operation. The working state and water flow parameters of the water valve are monitored in real time through the sensor control module 33, and the opening degree of the valve is accurately controlled by adjusting the speed and direction of the drive motor 31 according to the preset program or external signal, so as to realize accurate adjustment of the water flow. The solar panel 35 is installed on the upper end of the motor fixed support 34, ensuring that the installation angle of the solar panel 35 is reasonable, and it can fully receive sunlight to provide stable energy supply for the electric control assembly 3.

[0053] As shown in Figure 7 and Figure 8 , the flowmeter 16 and the protective shell 17 are arranged on the outer peripheral arm of the water outlet 15, and the flowmeter 16 is wrapped by the protective shell 17. The water flow of the water valve is measured by the flowmeter 16. The protective shell 17 is fixed on the valve base plate 13, ensuring the stable and reliable operation of the flowmeter 16 in complex working environments. The protective shell 17 is made of high-strength engineering plastic and has an isolation layer inside, which can play a role in waterproofing and dustproofing, effectively protecting the flowmeter 16 from external physical impact, dust invasion and water splash erosion, and prolonging the service life.

[0054] Example 2

[0055] As shown in Figure 9As shown, preferably, the bottom of the main shaft 21 is provided with a second groove 212 that slides and engages with the lifting screw 12. A wear-resistant bushing can also be provided in the second groove 212, which can slide up and down within a certain range and reduce wear. At the same time, the sliding connection can also be changed to a rotating connection or a fixed connection depending on the applicable scenario.

[0056] Example 3

[0057] like Figure 10 As shown, preferably, a removable filter screen 18 is provided at the front or rear end of the water outlet 15 on the valve base plate 13. This effectively filters impurities such as mud and particles from the water without excessively obstructing the water flow. By providing a filter screen 18 at the water outlet 15, impurities are prevented from entering the valve, reducing wear on components such as the gate 11 and the lifting screw 12, thus extending the valve's service life. Any aspects not described in this invention can be achieved by using or referencing existing technologies.

[0058] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0059] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
