[0041] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the following further details the technical solutions of the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope protected by this application.

[0042] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0043] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature can include the direct contact between the first and second features, or can also include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

[0044] In the agricultural irrigation scenario, in order to achieve the purpose of precise drip irrigation, an electric valve device with full-automatic control is required to adjust the opening degree. At the same time, an antenna structure is also arranged in the electric valve, and a wireless connection is established with a remote control terminal through the antenna structure to achieve the purpose of remote monitoring and controlling the operation of the valve by the user. Existing electric valves generally use omnidirectional antennas. An omnidirectional antenna is an antenna that can uniformly receive and transmit signals 360° in the horizontal direction. Its radiation pattern is similar to an apple shape, and the signal strength is evenly distributed in all directions. It has no specific requirements for the installation angle. However, the gain of an omnidirectional antenna is generally below 9 dB, the signal is difficult to penetrate objects, and it is more significantly affected by the multipath effect, and the problem of signal quality degradation is likely to occur. Generally speaking, existing electric valves using omnidirectional antennas have defects such as poor signal quality, low penetration ability, and poor stability.

[0045] To overcome the above technical problems, refer to Figures 1-11This embodiment provides an electric valve, including a valve body and a valve controller 3, the valve body and the valve controller 3 are connected, the electric valve also includes an antenna assembly, the antenna assembly includes a directional antenna 1 for sending and receiving wireless signals; the directional antenna 1 can be rotatably installed on the valve controller 3 or the valve body, so that the radio frequency direction of the directional antenna 1 is adjustable.

[0046] Specifically, the electric valve of this embodiment includes a valve body and a valve controller 3. The valve body can be, but is not limited to, a valve structure such as a ball valve, a butterfly valve, or a gate valve. The valve body includes a valve housing and a valve core installed in the valve housing. The valve core is connected to a valve handle extending out of the valve housing. The valve handle is connected to the valve controller 3. The valve core is driven to rotate by the valve controller 3 to achieve the function of adjusting the opening of the valve body.

[0047] Optionally, the valve controller 3 includes a controller housing 31 and a motor 32, a reduction mechanism 33 and a main control board 34 installed in the controller housing 31. The main control board 34 is electrically connected to the motor 32. The reduction mechanism 33 is transmission-connected to the motor 32 and the valve handle. The operation of the motor 32 is controlled by the main control board 34, so that the motor 32 can drive the valve core to rotate through the reduction mechanism 33, thereby realizing the function of automatically adjusting the opening of the valve body.

[0048] According to actual conditions, the directional antenna 1 of this embodiment can be installed on the valve controller 3 or the valve body, and a main control board 34 is provided in the valve controller 3. The directional antenna 1 needs to establish a signal connection with the main control board 34 to realize communication between the directional antenna 1 and the main control board 34.

[0049] Preferably, the directional antenna 1 is rotatably mounted on the valve controller 3. Mounting the directional antenna 1 on the valve controller 3 is more convenient for signal connection with the main control board 34 inside the valve controller 3.

[0050] The directional antenna 1 has the advantages of high gain, good signal quality, strong signal penetration and good signal stability. The directional antenna 1 used in this solution can overcome the problems existing in the existing electric valve using omnidirectional antennas.

[0051] However, the main feature of the directional antenna 1 is its ability to concentrate the radiation and reception of electromagnetic waves in one direction, forming a relatively strong electromagnetic field. Its radiation pattern is similar to an inverted cone, and the main radiation range is concentrated in the direction pointed by the antenna. In other words, when the directional antenna 1 is applied, there are relatively high requirements for the installation direction. It can only be installed in the correct direction (such as the direction towards network devices such as servers / relays) to effectively exert its communication function. However, in many cases, the installation direction of the electric valve is determined by the pipeline layout. After the electric valve is installed, the orientation of the directional antenna 1 on it may not be accurate. Especially in agricultural irrigation applications, the pipelines in the irrigation system are intricate, and pipelines with various orientations cause many electric valves in the system to face different directions, so it is inevitable that the directional antennas 1 of some electric valves cannot correctly face the network devices.

[0052] To overcome the above technical problems, in this embodiment, the installation of the directional antenna 1 is set to be rotatable, so that after the electric valve is installed in place, the direction of the directional antenna 1 can be rotated and adjusted according to the orientation of the network device to ensure that the directional antenna 1 can communicate reliably with the network device.

[0053] Preferably, the antenna board 123 of the directional antenna 1 is generally a long strip plate extending vertically upward from the ground, so that it can receive more wireless signals in the vertical direction. For the rotation adjustment of the directional antenna 1, the rotation center is perpendicular to the ground, so that after the directional antenna 1 rotates, it can correctly face the network device located on the ground in the distance.

[0054] Optionally, the adjustment of the orientation of the directional antenna 1 can be electrically controlled or manually adjusted. Preferably, the orientation of the directional antenna 1 adopts a manual adjustment form. The reason is that the position of the network device is generally fixed, so the orientation of the directional antenna 1 only needs to be adjusted well when the electric valve is installed. There is no need to perform adjustment work during use. The manual adjustment form has the advantages of simple structure and low cost. In addition, to ensure the stability of the directional antenna 1 after adjustment, a locking structure that can lock it after rotation can be set, or a structure that increases the damping can be set in its rotation structure to increase the difficulty of the directional antenna 1 rotating under the action of natural external forces.

[0055] In summary, for the electric valve based on this embodiment, the directional antenna 1 is used for signal transmission and reception. The directional antenna 1 has the advantages of high gain, good signal quality, strong signal penetration ability, and good signal stability, and can overcome the problems existing in the existing electric valves using omnidirectional antennas. Importantly, the directional antenna 1 of this solution is rotatably installed. After the electric valve is installed in place, the directional antenna 1 can be rotated to adjust its RF direction, so that the directional antenna 1 can face the direction with the strongest communication signal with network devices such as servers / repeaters, thereby ensuring that each directional antenna 1 can communicate with network devices in the most efficient and stable manner, and ensuring that users can reliably monitor and control each electric valve.

[0056] In one embodiment, referring to Figure 3 , the antenna assembly further includes an antenna support 2, the antenna support 2 is fixed to the valve controller 3 or the valve body, and the directional antenna 1 is rotatably installed on the antenna support 2.

[0057] Specifically, when the directional antenna 1 is installed on the valve controller 3, the antenna support 2 is installed on the valve controller 3; when the directional antenna 1 is installed on the valve body, the antenna support 2 is installed on the valve body.

[0058] The antenna support 2 needs to be firmly fixed to the valve controller 3 or the valve body to ensure stability during the rotation and adjustment of the antenna. Bolts, welding, or other mechanical connection methods can be used to achieve the fixation.

[0059] The antenna support 2 is provided for installing the directional antenna 1, making the installation of the directional antenna 1 more flexible and stable.

[0060] Regarding the rotational installation form of the directional antenna 1, in one embodiment, the directional antenna 1 includes an antenna housing 11 and an antenna body 12 installed inside the antenna housing 11, and the antenna body 12 is rotatably installed on the antenna support 2.

[0061] The antenna housing 11 is provided to protect the antenna body 12 from the influence of the external environment, such as dust, moisture, mechanical shock, etc. This helps to extend the service life of the antenna body 12 and ensure its stable performance. In this embodiment, it is set that the antenna body 12 can rotate independently, so the antenna housing 11 can be directly fixedly connected to the controller housing 31 of the valve controller 3, and the antenna housing 11 does not need to rotate. The fixed connection method is more conducive to ensuring the sealing performance of the connection between the antenna housing 11 and the controller housing 31, which is beneficial to strengthening the sealing protection of the internal antenna body 12.

[0062] Regarding the rotatable installation form of the directional antenna 1, in another embodiment, the directional antenna 1 includes an antenna housing 11 and an antenna body 12 installed in the antenna housing 11, and the antenna housing 11 can be rotatably installed on the antenna support 2.

[0063] In this embodiment, the antenna housing 11 is directly rotatably mounted on the antenna support 2 . When rotating, the antenna housing 11 and the antenna body 12 inside rotate together, so the antenna body 12 can be directly fixedly mounted in the antenna housing 11 .

[0064] In one embodiment, the antenna body 12 includes an antenna plate 123 and an antenna bracket 121 . The antenna plate 123 is mounted on the antenna bracket 121 . The antenna bracket 121 is rotatably mounted on the antenna support 2 .

[0065] The antenna plate 123 is the core part of the antenna body 12, responsible for radiating and receiving wireless signals. It is usually made of conductive materials and is designed with specific shapes and sizes to achieve the desired radiation pattern and performance. The main function of the antenna bracket 121 is to support the antenna plate 123 and provide a rotatable platform so that the user can adjust the direction of the antenna as needed. It is also responsible for connecting the antenna body 12 with the antenna support 2 to ensure that the antenna body 12 can rotate smoothly. The antenna bracket 121 of this solution is used to install the structure of the antenna plate 123, which can ensure the stability and reliability of the antenna plate 123 during rotation.

[0066] To avoid signal shielding, preferably, the antenna bracket 121 and the antenna housing 11 are both made of plastic.

[0067] In one embodiment, the directional antenna 1 further includes a rotating member 13 , wherein the rotating member 13 is at least partially located outside the antenna housing 11 , and the rotating member 13 is connected to the antenna bracket 121 , and the rotating member 13 is used to drive the antenna bracket 121 to rotate.

[0068] The main function of the rotating member 13 is to serve as an interface for the user to operate the rotation of the antenna. The user can apply a rotational force by manually turning the rotating member 13, thereby driving the antenna body 12 to rotate together. The design of the rotating member 13 makes the adjustment of the direction of the directional antenna 1 intuitive and easy to use, and the user can easily get started without reading complicated instructions or receiving professional training. Since the rotating member 13 allows the user to adjust the direction of the antenna anytime and anywhere, the design has strong flexibility, and the user can quickly respond and adjust the direction of the antenna according to changes in the actual network environment. In addition, since the connection mechanism between the rotating member 13 and the antenna bracket 121 is relatively simple, the maintenance cost of the design is also relatively low, and even if it fails or is damaged, the user can easily repair or replace it.

[0069] Preferably, an indication mark is provided on the rotating member 13, and the user can identify the orientation of the internal antenna board 123 through the indication mark, which facilitates quickly and accurately rotating the antenna board 123 to the correct direction.

[0070] Regarding the setting form of the rotating member 13, in one embodiment, in combination with Figure 1 and Figure 3 , a connection hole with an axis coinciding with the rotation center of the antenna bracket 121 is provided at the top of the antenna housing 11, and the rotating member 13 extends into the antenna housing 11 through the connection hole and connects the antenna bracket 121.

[0071] In this embodiment, since the axis of the connection hole coincides with the rotation center of the antenna bracket 121, the rotating member 13 can be set to completely block the connection hole, and the part of the rotating member 13 located outside the antenna housing 11 can be set to completely cover the top of the antenna housing 11. In this way, the problem that rainwater seeps into the antenna housing 11 through the connection hole and causes the antenna board 123 to get wet can be effectively avoided. That is, this structure is beneficial to improving the waterproof performance of the directional antenna 1 in this embodiment.

[0072] Preferably, the rotating member 13 includes a connection head 1211, a waterproof ring 1212 is sleeved on the connection head 1211, the connection head 1211 extends into the antenna housing 11 through the connection hole and connects the antenna bracket 121, and the waterproof ring 1212 abuts against the hole wall of the connection hole.

[0073] When the rotating member 13 is provided with a connection head 1211 to extend into the antenna housing 11 to connect the antenna bracket 121, and a waterproof ring 1212 is sleeved on the outer periphery of the connection head 1211, the waterproof ring 1212 can fill the gap between the connection hole and the connection head 1211, thereby further improving the waterproof ability of the directional antenna 1.

[0074] Regarding the setting form of the rotating member 13, in another embodiment, referring to Figure 4 and Figure 6 , a connection hole with an axis coinciding with the rotation center of the antenna bracket 121 is provided at the top of the antenna housing 11, and the antenna bracket 121 extends out of the antenna housing 11 through the connection hole and connects the antenna bracket 121.

[0075] In this embodiment, since the axis of the connection hole coincides with the rotation center of the antenna bracket 121, the part of the antenna bracket 121 extending out of the connection hole can be set to completely block the connection hole, and the rotating member 13 can be set to completely cover the top of the antenna housing 11. In this way, the problem that rainwater seeps into the antenna housing 11 through the connection hole and causes the antenna board 123 to get wet can be effectively avoided. Similarly, this structure is beneficial to improving the waterproof performance of the directional antenna 1 in this embodiment.

[0076] Preferably, the antenna bracket 121 includes a connector 1211, the connector 1211 is sleeved with a waterproof ring 1212, the connector 1211 extends out of the antenna housing 11 through the connecting hole and is connected to the rotating member 13, and the waterproof ring 1212 abuts against the hole wall of the connecting hole.

[0077] Similarly, a connector 1211 is provided on the antenna bracket 121 to extend to the outside of the antenna housing 11 to connect to the rotating part 13, and a waterproof ring 1212 is sleeved on the outer periphery of the connector 1211. The waterproof ring 1212 can fill the gap between the connecting hole and the connector 1211, thereby further improving the waterproof capability of the directional antenna 1.

[0078] Regarding the setting form of the rotating member 13, in another embodiment, a dial hole is provided on the side of the antenna housing 11, and the rotating member 13 includes a lever, which extends into the antenna housing 11 through the dial hole and is connected to the antenna bracket 121. The lever can swing along the dial hole relative to the antenna housing 11, so that the antenna bracket 121 can be driven to rotate through the lever.

[0079] The lever is the main part of the rotating member 13. One end of the lever extends to the outside of the antenna housing 11 through the rotating hole for user operation. The other end is connected to the antenna bracket 121 for transmitting the rotating force. The user can realize the rotating operation by turning the lever located outside the antenna housing 11. The lever can swing along the rotating hole relative to the antenna housing 11. This swinging motion can drive the antenna bracket 121 to rotate.

[0080] In one embodiment, referring to Figure 5 One of the antenna support 2 and the antenna bracket 121 is provided with a rotating support 21, and the other is provided with a rotating sleeve 1213. The rotating sleeve 1213 can be rotatably sleeved on the antenna support 2 to realize the rotatable installation of the antenna bracket 121 on the antenna support 2.

[0081] The design of the rotating support 21 and the rotating sleeve 1213 is relatively simple, easy to manufacture and install. The rotating sleeve 1213 and the rotating support 21 are tightly matched and have low friction, and the antenna bracket 121 can achieve flexible and stable rotation. This mechanical structure has high durability and can withstand long-term use and frequent rotation operations.

[0082] In one embodiment, in combination Figure 1 and Figure 2 The valve controller 3 includes a controller housing 31, and the controller housing 31 includes a bottom housing 311 and a housing cover 312. The antenna housing 11 and the housing cover 312 are an integrated structure.

[0083] The controller housing 31 consists of two parts: a bottom shell 311 and a shell cover 312. The bottom shell 311 serves as the basic support part of the controller and usually contains installation spaces for core components such as a main control board 34, a battery, sensors, a reduction mechanism 33, and a motor 32. The shell cover 312 covers the top of the bottom shell 311, playing a role in protecting internal components and sealing against dust. Since the antenna housing 11 is integrated with the shell cover 312, the antenna can be more closely integrated inside the valve controller 3. This design helps to optimize the layout and orientation of the antenna, facilitating the electrical connection between the antenna board 123 and the main control board 34. The integrated structure design also makes the appearance of the valve controller 3 cleaner and more aesthetically pleasing, avoiding possible gaps or protrusions between the antenna and the controller housing 31 in traditional designs and enhancing the overall texture of the product. Importantly, the integrated structure design reduces the number of components and assembly steps, lowers the manufacturing cost and complexity, makes the connection between the antenna and the controller more stable and reliable, reduces the risk of failures caused by loosening or detachment, and improves the dust and water protection capabilities of the entire valve controller 3 and the directional antenna 1.

[0084] In one implementation, in combination with Figure 7 and Figure 10 , the valve controller 3 includes a motor 32 installed in the bottom shell 311. The antenna support 2 includes a support column 22 and an upper support plate 23 connected to the top side of the support column 22. The support column 22 and the upper support plate 23 enclose a receiving recess 24 corresponding to the outer shape of the motor 32. The bottom side of the support column 22 is fixed to the bottom shell 311, and the motor 32 is placed in the receiving recess 24. The antenna body 12 is rotatably installed on the top side of the upper support plate 23.

[0085] The antenna support 2 includes a support column 22 and an upper support plate 23. The support column 22 surrounds the motor 32, forming a certain protection barrier and enabling the bottom of the support column 22 to be fixedly connected to the bottom shell 311 to achieve reliable fixation of the antenna support 2. The upper support plate 23 is connected to the top side of the support column 22, and the two together enclose a receiving recess 24 corresponding to the outer shape of the motor 32. Importantly, the upper support plate 23 provides an installation platform for the antenna body 12, allowing the antenna body 12 to be installed above the upper support plate 23, forming a valve controller 3 with a compact structure and perfect functions.

[0086] Preferably, with reference to Figure 10The bottom shell 311 includes a middle partition 3121, a speed reduction mechanism 33 is installed below the middle partition 3121, a motor 32 and a main control board 34 are installed above the middle partition 3121, and the shell cover 312 covers the motor 32, the main control board 34 and the middle partition 3121 from top to bottom. The speed reduction mechanism 33 and the motor 32 and the main control board 34 above can be separated by the middle partition 3121 to avoid interference or contamination between the two cavities. Among them, the middle partition 3121 is provided with a through hole that allows the shaft of the motor 32 to pass through at the installation position corresponding to the motor 32, and the shaft of the motor 32 passes through the through hole to be connected with the speed reduction mechanism 33 in transmission.

[0087] In one embodiment, in combination Figure 10 and Figure 11 The upper support plate 23 is provided with a mounting groove 231 , in which a motor control board 322 is installed, and the motor control board 322 is electrically connected to the motor 32 .

[0088] Specifically, the motor control board 322 is connected to the motor 32 to receive instructions from the main control board 34 and control the operation of the motor 32. By providing the mounting slot 231 on the upper support plate 23 and installing the motor control board 322, the internal structure of the entire valve controller 3 is made more compact and orderly, which not only saves space but also improves the aesthetics of the product.

[0089] In one embodiment, the motor 32 includes an electrode sheet 321 , and an electrode avoidance hole 232 is provided on the upper support plate 23 . The electrode sheet 321 passes through the electrode avoidance hole 232 and is connected to the motor control board 322 through a wire.

[0090] Specifically, the electrode sheet 321 includes a cathode sheet and an anode sheet. The design of the electrode avoidance hole 232 simplifies the installation process of the motor 32, so that the electrode sheet 321 can easily pass through the upper support plate 23 and connect to the control board, and it is convenient to use a shorter wire directly above the upper support plate 23 to connect the motor 32 to the motor control board 322, thereby ensuring the reliability and stability of the signal transmission between the motor 32 and the control board.

[0091] In one embodiment, the directional antenna 1 is provided with a first rotation limit portion, and the antenna support 2 is provided with a second rotation limit portion cooperating with the first rotation limit portion, and the rotatable angle of the directional antenna 1 is limited within 360° through the cooperation between the first rotation limit portion and the second rotation limit portion.

[0092] Inside the directional antenna 1, there are usually signal transmission lines, which are connected to the main control board 34. Through the cooperation of the first rotation limiting part and the second rotation limiting part, the rotatable angle of the directional antenna 1 is effectively limited within 360°. This design not only improves the stability and reliability of the device but also avoids potential problems such as winding and breaking of internal lines caused by excessive rotation of the directional antenna 1.

[0093] The first rotation limiting part is one or more limiting structures provided on the directional antenna 1, which are used to cooperate with the second rotation limiting part on the antenna support 2 when the antenna rotates. These limiting structures can be mechanical protrusions, grooves, or stoppers, etc., and the specific form depends on the design requirements and implementation methods. The second rotation limiting part is the structure corresponding to the first rotation limiting part on the antenna support 2, which is used to provide physical limitation during the rotation of the antenna. When the first rotation limiting part contacts the second rotation limiting part, the further rotation of the antenna will be blocked, thus realizing the limitation of the rotation angle of the antenna.

[0094] In one embodiment, the first rotation limiting part is the first bump 12132 provided on the directional antenna 1, and the second rotation limiting part is the second bump 211 provided on the antenna support 2.

[0095] When the directional antenna 1 starts to rotate, the first bump 12132 will move together with the directional antenna 1. As the rotation angle increases, the first bump 12132 will gradually approach and finally contact the second bump 211. Once the two contact, the further rotation of the antenna will be blocked, thus realizing the limitation of the rotation angle. Using bumps as the rotation limiting part, the structural design is simple and clear, and it is easy to manufacture and install.

[0096] Optionally, in combination with Figure 7 and Figure 9 , an inner shoulder 12131 is provided on the inner wall of the rotating sleeve 1213 of the antenna support 121. A first bump 12132 is provided on the side of the inner shoulder 12131 close to the rotating pillar 21; a second bump 211 is provided on the side of the rotating pillar 21 close to the inner shoulder 12131. After the rotating sleeve 1213 is sleeved on the rotating pillar 21, the second bump 211 abuts against the inner shoulder 12131. When rotating to a certain angle, the first bump 12132 abuts against the second bump 211, thereby restricting the further rotation of the directional antenna 1.

[0097] In one embodiment, the antenna body 12 includes a signal reflection aluminum plate 122 and an antenna board 123 installed on one side of the signal reflection aluminum plate 122.

[0098] The main function of the signal reflection aluminum plate 122 is to reflect and concentrate electromagnetic wave signals. When the electromagnetic wave signals radiate from the antenna plate 123, some signals may scatter in all directions, resulting in a weakening of the signal intensity. The signal reflection aluminum plate 122 can reflect these scattered signals back to the antenna plate 123, thereby enhancing the directivity and gain of the antenna. Therefore, the combination of the signal reflection aluminum plate 122 and the antenna plate 123 in this solution can enhance the directivity and gain of the antenna and improve the overall performance of the antenna.

[0099] On the other hand, this embodiment provides an irrigation system including the above-mentioned electric valve.

[0100] Based on the electric valve of this embodiment, the signal transmission in the irrigation system of this embodiment is more stable, so it has advantages such as stable control and good reliability.
