[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figures 1-8 , is the first embodiment of the present utility model, which provides an intelligent valve for agricultural irrigation. The intelligent valve for agricultural irrigation includes a main body component 100, including a water delivery pipe 101, a solar bracket 102, a solar panel 103, a valve body 104 and a control mechanism 105. The solar bracket 102 is located above the water delivery pipe 101, the solar panel 103 is fixed on the solar bracket 102, the valve body 104 is fixed on the water delivery pipe 101, and the control mechanism 105 is fixed on one side of the solar bracket 102.

[0032] The solar panel 103 is used to provide energy for the irrigation valve, the valve body 104 is used to control the conduction and cutoff of irrigation water, and the control mechanism 105 can collect various irrigation-related data and formulate corresponding irrigation strategies based on the data. This is the existing technology and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0033] The solar panel 103 converts the received solar energy into electrical energy, and the electrical energy generated by the solar panel 103 is stored in a battery to continuously provide energy for the control of the valve body 104. In the irrigation system, there are various sensors to monitor parameters related to irrigation. The controller in the control mechanism 105 receives the signal from the sensor. When the controller receives a signal that the soil moisture is low, it will process it according to a preset program. If it decides to irrigate, the controller will obtain electrical energy from the storage battery charged by the solar panel to drive the actuator. The actuator is connected between the controller and the valve body 104. The controller sends an electrical signal to the electric push rod, and the electric push rod pushes the valve core of the valve body 104 through a mechanical connection. If the valve is to be opened, the electric push rod will push the valve core away from the valve seat, so that the water flow channel is opened, thereby realizing the conduction of irrigation water; when the irrigation meets the predetermined requirements, the controller sends a signal again, and the electric push rod reverses the action, pushing the valve core back to the valve seat, closing the valve body 104, and stopping irrigation.

[0034] The cleaning assembly 200 includes a cleaning member 201, which is arranged on one side of the solar panel 103, a motor 201a, a rotating shaft 201b, a first winding wheel 201c, a first pull rope 201d, a guide rail 201e and a cleaning plate 201f. The motor 201a is located above the water delivery pipe 101, the rotating shaft 201b is fixed to one side of the motor 201a, the first winding wheel 201c is sleeved on the outside of the rotating shaft 201b, the first pull rope 201d is wound around the first winding wheel 201c, the guide rail 201e is fixed on both sides of the solar bracket 102, and the guide rail 201e is provided with a movable groove 201e-1, and the cleaning plate 201f slides in the movable groove 201e-1.

[0035] The cleaning member 201 is used to clean the surface of the solar panel 103 . The other end of the first pull rope 201d is fixed to the cleaning plate 201f . Cleaning cotton is fixed to the side of the cleaning plate 201f close to the solar panel 103 . The cleaning cotton is in contact with the surface of the solar panel 103 .

[0036] When the motor 201a drives the rotating shaft 201b to rotate, the rotating shaft 201b will drive the first winding wheel 201c to rotate, thereby tightening the first pull rope 201d. At this time, the cleaning plate 201f will move along the movable groove 201e-1 under the tension of the first pull rope 201d, so that the cleaning cotton can clean the surface of the solar panel 103, ensuring that the solar panel 103 always maintains a high working efficiency, avoiding valve operation failure caused by contamination of the solar panel 103, and improving the reliability of the system.

[0037] The cleaning assembly 200 also includes an auxiliary part 202, which is arranged on one side of the solar panel 103, including a fixed shaft 202a, a protective plate 202b, a second winding wheel 202c, a second pull rope 202d, a support platform 202e and a limit plate 202f. The fixed shaft 202a is located on one side of the solar panel 103, the protective plate 202b is sleeved on the outside of the fixed shaft 202a, the second winding wheel 202c is sleeved on the rotating shaft 201b, the second pull rope 202d is wound around the second winding wheel 202c, the support platform 202e is arranged below the rotating shaft 201b, and the limit plate 202f is fixed on the support platform 202e.

[0038] The support platform 202e is used to support the motor 201a and the rotating shaft 201b. The other end of the second pull rope 202d is fixed to the protective plate 202b. The limiting plate 202f is used to limit the rotation angle of the protective plate 202b.

[0039] When the motor 201a drives the rotating shaft 201b to rotate, the rotating shaft 201b will drive the second winding wheel 202c to rotate, thereby tightening the second pull rope 202d. Under the pull of the second pull rope 202d, the protective plate 202b will rotate around the fixed shaft 202a, thereby opening the protective plate 202b to avoid affecting the normal operation of the solar panel 103.

[0040] Example 2

[0041] Reference Figures 1-8 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0042] Specifically, the cleaning component 200 also includes a water spray part 203, which is arranged on one side of the water delivery pipe 101, including a water spray pipe 203a, a ring 203b, a baffle 203c, a connecting plate 203d, a rotating plate 203e, a connecting block 203f, an extension plate 203g and a protrusion 203h. The water spray pipe 203a is fixed on the water delivery pipe 101, the ring 203b is fixed in the water spray pipe 203a, the baffle 203c is arranged in the water spray pipe 203a, the connecting plate 203d is fixed to one side of the baffle 203c, the connecting block 203f is fixed to the protective plate 202b, the extension plate 203g is fixed to one side of the connecting block 203f, and the protrusion 203h is fixed to one end of the extension plate 203g.

[0043] The water spraying member 203 draws out a portion of the irrigation water to humidify and clean the cleaning plate 201f, thereby achieving rational use of water resources, reducing the demand for additional cleaning water sources, and improving the cleaning effect.

[0044] Through the setting of the ring 203b and the baffle 203c, when the two are separated, the irrigation water in the water delivery pipe 101 will flow out from the water spray pipe 203a to humidify and clean the cleaning cotton on the cleaning plate 201f. When the two are tightly fitted, the irrigation water will not flow out from the water spray pipe 203a, avoiding waste of water resources.

[0045] When the protective plate 202b is in the open state, the motor 201a is started to drive the protective plate 202b to rotate, and the connecting block 203f rotates accordingly, thereby driving the extension plate 203g and the protrusion 203h to rotate. When the protrusion 203h contacts the rotating plate 203e, it will squeeze the rotating plate 203e and move it downward, driving the baffle 203c to move downward, separating the ring 203b from the baffle 203c, so that the irrigation water in the water delivery pipe 101 will gush out from the water spray pipe 203a, humidifying and cleaning the cleaning cotton on the cleaning plate 201f.

[0046] Specifically, a first spring 201g is fixed to one side of the cleaning plate 201f, and the other end of the first spring 201g is fixed to the inner wall of the moving groove 201e-1.

[0047] The first spring 201g is configured to apply a continuous pulling force to the cleaning plate 201f. When the cleaning plate 201f moves to a position close to the fixed shaft 202a, the first spring 201g will be in a stretched state. When the motor 201a drives the rotating shaft 201b and the first winding wheel 201c to rotate in the opposite direction, the first pull rope 201d is loosened. At this time, the cleaning plate 201f returns to its initial position under the action of the first spring 201g, moves to the other end of the movable slot 201e-1, and cleans the solar panel 103 again.

[0048] Specifically, a first torsion spring 202i is fixed to one side of the protective plate 202b, and fixed blocks 202j are fixed to both sides of the fixed shaft 202a.

[0049] There are two fixed blocks 202j, which are used to support the fixed shaft 202a. The two ends of the first torsion spring 202i are respectively fixed to the fixed block 202j and the protective plate 202b. The setting of the first torsion spring 202i drives the protective plate 202b to reset. The motor 201a is started to charge the first torsion spring 202i. When the motor 201a reverses, it drives the rotating shaft 201b and the second winding wheel 202c to reverse, thereby loosening the second pull rope 202d. At this time, the first torsion spring 202i will release energy and drive the protective plate 202b to rotate in the opposite direction, so that the protective plate 202b is closed to protect the solar panel 103.

[0050] Specifically, a support column 202k is fixed on the support platform 202e, and the support column 202k is sleeved outside the rotating shaft 201b.

[0051] There are two supporting columns 202k for supporting the rotating shaft 201b without hindering the rotation of the rotating shaft 201b.

[0052] Specifically, a guide wheel 2021 is provided on the fixed shaft 202a.

[0053] The guide wheel 2021 is used to guide the first pull rope 201d to the first winding wheel 201c. The guide wheel 2021 is rotatably connected to the fixed shaft 202a to prevent the first pull rope 201d from contacting the fixed shaft 202a, thereby reducing friction.

[0054] Example 3

[0055] Reference Figures 1-8 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0056] Specifically, a rotating shaft 203i is plugged into the connecting plate 203d, and a second torsion spring 203j is provided on the outer sleeve of the rotating shaft 203i.

[0057] The other end of the second torsion spring 203j is fixed to the rotating plate 203e. The arrangement of the rotating shaft 203i and the second torsion spring 203j ensures that the rotating plate 203e can return to its initial position after rotating around the rotating shaft 203i.

[0058] Specifically, a limiting block 203k is fixed at the bottom of the connecting plate 203d, and a guide groove 203d-1 is formed in the connecting plate 203d. A guide column 2031 is inserted into the guide groove 203d-1, and a second spring 203m is provided on the outer sleeve of the guide column 2031.

[0059] The limit block 203k is used to limit the rotating plate 203e to rotate in one direction. During the opening process of the protective plate 202b, the rotating plate 203e can rotate without affecting the opening of the protective plate 202b.

[0060] The second spring 203m applies a continuous thrust to the connecting plate 203d to ensure that, in the absence of other examples, the ring 203b fits tightly against the baffle 203c and the irrigation water does not gush out of the water spray pipe 203a.

[0061] Specifically, the surface of the protection plate 202b close to the solar panel 103 is made of a reflective material.

[0062] This enhances refraction and provides the solar panel 103 with a longer illumination time.

[0063] During use, the protective plate 202b is in a closed state at night. At this time, the cleaning plate 201f is located in the movable slot 201e-1 away from the fixed axis 202a. When the protective plate 202b needs to be opened, the starting motor 201a drives the rotating shaft 201b to rotate, and drives the second winding wheel 202c to rotate to tighten the second pull rope 202d. Under the pull of the second pull rope 202d, the protective plate 202b will rotate around the fixed axis 202a, thereby opening the protective plate 202b to avoid affecting the normal operation of the solar panel 103.

[0064] At the same time, the motor 201a drives the rotating shaft 201b to rotate, and the rotating shaft 201b will drive the first winding wheel 201c to rotate, thereby tightening the first pull rope 201d. At this time, the cleaning plate 201f will move along the movable groove 201e-1 under the tension of the first pull rope 201d, so that the cleaning cotton can clean the surface of the solar panel 103, ensuring that the solar panel 103 always maintains a high working efficiency, avoiding valve operation failure caused by contamination of the solar panel 103, and improving the reliability of the system.

[0065] When the protective plate 202b is opened, the connecting block 203f rotates as the protective plate 202b opens, thereby driving the extension plate 203g and the protrusion 203h to rotate. When the protrusion 203h contacts the rotating plate 203e, the rotating plate 203e rotates around the rotating shaft 203i and will not hinder the rotation of the protective plate 202b.

[0066] When the protective plate 202b needs to be closed, the motor 201a reverses, driving the rotating shaft 201b and the second winding wheel 202c to reverse, thereby relaxing the second pull rope 202d. At this time, the first torsion spring 202i will release energy, driving the protective plate 202b to rotate in the opposite direction, thereby closing the protective plate 202b to protect the solar panel 103. At the same time, the protective plate 202b drives the connecting block 203f to rotate, thereby driving the extension plate 203g and the protrusion 203h to rotate. When the protrusion 203h contacts the rotating plate 203e, it squeezes the rotating plate 203e. The rotating plate 203e is restricted by the limit block 203k and cannot rotate, thereby moving downward, thereby driving the connecting plate 203d to move, and driving the baffle 203c to move downward, separating the ring 203b from the baffle 203c, so that the irrigation water in the water supply pipe 101 will gush out from the water spray pipe 203a, humidifying and cleaning the cleaning cotton on the cleaning plate 201f.

[0067] The reverse rotation of the rotating shaft 201b will also drive the first winding wheel 201c to rotate in the opposite direction. At this time, the first pull rope 201d is loosened, and the cleaning plate 201f returns to the initial position under the action of the first spring 201g, moves to the other end of the moving groove 201e-1, and cleans the solar panel 103 again.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
