Description

Technical Field

[0001] This application relates to the technical field of valves, and particularly to an electric valve and an irrigation system. Background Art

[0002] In agricultural irrigation scenarios, in order to achieve accurate irrigation, a fully automatic controlled electric valve device is required to adjust the opening degree. At the same time, an antenna structure is also provided in the electric valve. By using the antenna structure to establish a wireless connection with a remote control terminal, the purpose of remotely monitoring and controlling the operation of the valve by the user can be achieved. The antennas of existing valves are generally directly arranged on the valve controller. Since electric valves are generally installed close to the ground, the antennas are installed at a relatively low position. When the crops grow tall, the antennas will be submerged among the crops, which results in the antenna receiving signals being easily blocked and interfered by the crops, affecting the strength and stability of the antenna receiving signals.

[0044] To make the technical problems solved by the present application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0045] In the description of the present application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may 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 the first feature being directly above and obliquely above the second feature, or merely indicating 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 the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0047] In agricultural irrigation scenarios, in order to achieve precise irrigation purposes, it is necessary to use a fully automatically controlled electric valve device to adjust the opening and closing degree. At the same time, an antenna structure is also provided in the electric valve, and a wireless connection is established with a remote control terminal by using the antenna structure to achieve the purpose of remote monitoring and control of the valve by the user. The antenna of the existing valve is generally directly set on the valve controller. Since the electric valve is generally installed close to the ground, the antenna is installed at a lower position. When the crops grow taller, the antenna will be submerged between the crops, which makes the antenna receiving signal easily blocked by the crops, affecting the strength and stability of the antenna receiving signal.

[0048] In order to overcome the above technical problems, combined Figures 1-6 This embodiment provides an electric valve, including a valve controller 2 and an antenna 1, the valve controller 2 includes a first connector 21; the antenna 1 includes an antenna body and a signal line 12 connected to the antenna body, the end of the signal line 12 away from the antenna body is connected to a second connector 121, and the second connector 121 is plug-connected to the first connector 21.

[0049] Specifically, the external antenna structure of this embodiment is applied to an electric valve, which includes a valve body 3 and a valve controller 2. The valve body 3 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 3 includes a valve shell and a valve core installed in the valve shell. The valve core is connected to a valve handle extending out of the valve shell. The valve handle is connected to the valve controller 2. The valve core is driven to rotate by the valve controller 2 to achieve the function of adjusting the opening of the valve body 3.

[0050] Optionally, the valve controller 2 includes a controller housing and a motor, a speed reduction mechanism and a main control board installed in the controller housing. The main control board is electrically connected to the motor, and the speed reduction mechanism is transmission-connected to the motor and the valve handle. The operation of the motor is controlled by the main control board, so that the motor can drive the valve core to rotate through the speed reduction mechanism, thereby realizing the function of automatically adjusting the opening of the valve body 3. The first connector 21 is electrically connected to the main control board. After the second connector 121 at the end of the signal line 12 is plugged and connected to the first connector 21, signal transmission between the antenna body and the main control board can be realized.

[0051] The utility model key point of this scheme is that the antenna 1 adopts an external structure. During installation, the antenna body can be installed to any required height, and the signal line 12 is set to have a sufficient length. After the antenna body is fixed separately, the second connector 121 at the end of the signal line 12 can be directly plugged into the first connector 21 of the valve controller 2 to realize signal transmission.

[0052] Among them, to fix the antenna body to a sufficient height, it can be fixed to the support 5 in the field. The support can be, for example, a support rod, so that the antenna body can be installed at the required height according to needs, ensuring the communication effect of the electric valve.

[0053] On the other hand, during the farming process, before sowing, soil turning operations are generally required, and when the crops are mature, harvesting is needed. Existing soil turning, sowing, harvesting and collection operations are generally mechanized operations. Therefore, to avoid mechanical damage to the irrigation system, the irrigation system needs to be arranged after sowing and removed and recycled before harvesting. Therefore, the electric valves in the irrigation system need to be disassembled and assembled frequently. The inventor of the present application found that the antenna 1 of the existing electric valve is a long strip-shaped structure fixedly connected to the top of the valve controller 2. When collecting and stacking multiple electric valves together, the problem often occurs that some antennas 1 are squeezed and bent or even broken, resulting in certain economic losses.

[0054] The external antenna structure of the solution of this embodiment can effectively avoid the above problems. Specifically, when removing and recycling the irrigation system, the second connector 121 can be first disconnected from the first connector 21, and then the antenna 1 can be separately recycled and stored together, while the electric valves without the antenna 1 are separately collected and stored together, so as to avoid the problem that the antenna 1 is squeezed and bent or even broken by the electric valve.

[0055] In summary, for the electric valve based on this embodiment, the antenna 1 is connected with a signal line 12 for transmitting signals. The first connector 21 and the second connector 121 are respectively arranged on the valve controller 2 and the signal line 12. When installing the antenna 1, the antenna body can be installed at a suitable height according to the scene requirements, and then the first connector 21 and the second connector 121 can be plugged and connected. Therefore, the antenna 1 of this solution adopts an external structure, and the installation height of the antenna 1 is not limited by the installation height of the valve controller 2 and can be installed at a higher position according to needs, so as to avoid the problem that the signal strength and stability received by the antenna 1 are affected after the surrounding crops grow tall.

[0056] In addition, when recycling the electric valve, the antenna 1 and the valve controller 2 can also be disassembled and stored separately, so as to avoid the problem that the antenna 1 is broken by extrusion and impact during storage.

[0057] In one embodiment, the antenna 1 includes an antenna housing 11, and the antenna body is installed inside the antenna housing 11.

[0058] Setting the antenna housing 11 to accommodate the antenna body not only protects the antenna body from the influence of external environments such as dust, moisture, mechanical shock and other factors, but also improves the stability and durability of the overall structure.

[0059] Preferably, a wire passing hole is provided at the bottom of the antenna housing 11. The signal wire 12 can pass through the wire passing hole and be connected to the internal antenna body. The wire passing hole provided at the bottom can prevent rainwater from seeping in. Further, a waterproof ring can be provided in the wire passing hole, and the waterproof ring is closely attached to the signal wire 12 to further enhance the waterproof ability.

[0060] In one embodiment, the antenna housing 11 is connected with a mounting connector 4, and the mounting connector 4 is used to be fixed to the support body 5, and the antenna 1 is supported and fixed by the support body 5.

[0061] Specifically, the support body 5 is a structure that can support the antenna 1 to a sufficient height. In specific applications, it can be adjusted according to local conditions. When there is a structure with sufficient height (such as a column, a roof structure, etc.) near the installation position of the electric valve in the field, this structure can be directly used as the support body 5, and the antenna 1 is fixed to the support body 5 through the mounting connector 4. When there is no structure near the installation position of the electric valve that can support the antenna 1 to the required height, a structure with sufficient height (such as a rod, a pipe fitting, etc.) can be separately provided to fix the antenna 1.

[0062] In this solution, the mounting connector 4 is set as a bridge between the antenna housing 11 and the support body 5, which can firmly fix the antenna housing 11 on the support body 5, preventing the antenna 1 from shaking or falling off due to wind force, vibration or other external forces, so as to ensure that the antenna 1 can maintain a stable posture and performance under various environmental conditions.

[0063] The mounting connector 4 can adopt methods such as but not limited to screw fixation, snap fixation, and hoop fixation according to requirements to adapt to support bodies 5 of different shapes and materials, which makes the installation of the antenna 1 more flexible and convenient, and the appropriate fixation method can be selected according to the actual situation.

[0064] Preferably, the mounting connector 4 also has the function of adjusting the angle, allowing the user to adjust the orientation and angle of the antenna 1 according to the need of signal reception to achieve the best signal reception effect.

[0065] In one embodiment, the mounting connector 4 is a hoop structure.

[0066] The hoop structure can be firmly fixed on the support body 5 through its unique clamping force, ensuring that the antenna housing 11 will not shake or fall off due to external forces. This firm fixation method enables the antenna 1 to maintain a stable posture and performance under various environmental conditions.

[0067] Meanwhile, the installation process of the hoop structure is relatively simple. Usually, it only needs to put the hoop on the support body 5 and fasten it with fasteners such as bolts and nuts. This installation method not only saves time but also reduces the installation difficulty, enabling users to easily complete the installation work of the antenna 1. In addition, the hoop structure can adapt to support bodies 5 of different shapes and sizes, such as circular, square, rectangular, etc. This wide adaptability makes the hoop structure an ideal choice for connecting the antenna housing 11 and the support body 5.

[0068] In one embodiment, the installation connecting piece 4 is a hose clamp, which includes a hoop band 41 and a locking piece 42. The locking piece 42 locks the hoop band 41 to make the hoop band 41 tightly hoop on the support body 5.

[0069] A hose clamp, also known as a clip or pipe clamp, is usually used for the fixing and connection of pipelines, cables or other circular objects. It includes a hoop band 41 and a locking piece 42. The hoop band 41 forms a circular shape, and a tightening space that can be sleeved on the support body 5 is formed inside it. By using the locking piece 42 to connect the two parts of the hoop band 41 at the same time, the tightening space can be locked, so that the whole hose clamp tightly sleeves on the support body 5.

[0070] During installation, first connect the hoop band 41 to the antenna housing 11, then put the hoop band 41 on the support body 5 and adjust it to a proper position; then, lock the two ends of the hoop band 41 through the locking piece 42 to make the hoop band 41 tightly hoop on the support body 5. In this way, the antenna 1 can be firmly fixed at the required height and position, ensuring the stability and reliability of signal reception.

[0071] This solution adopts a hose clamp structure as the installation connecting piece 4, which can easily adapt to the installation of support bodies 5 with various diameters. Moreover, the locking piece 42 has the characteristic of being easily tightened and loosened repeatedly, which is convenient for users to frequently disassemble and assemble the antenna 1. At the same time, it also has the advantage of good installation reliability. Preferably, the installation connecting piece 4 is usually made of corrosion-resistant materials such as stainless steel and galvanized steel, which can maintain stable performance under various harsh environmental conditions and extend the service life.

[0072] In one embodiment, the locking piece 42 includes a structure that can be tightened and loosened repeatedly. The locking piece 42 has a loose state and a tightened state. In the loose state, the hoop band 41 can move relative to the locking piece 42 to adjust the size of the tightening space. In the tightened state, the hoop band 41 is locked.

[0073] In the loosened state, the user can easily adjust the tightening and position of the strap 41 on the support body 5 to adapt to support bodies 5 of different diameters or shapes. This adjustment process is simple and fast, and can be completed without disassembling the hose clamp. In the tightened state, the locking member 42 can firmly lock the strap 41 in the required position, ensuring a stable connection between the antenna 1 and the support body 5. This locking method can resist external impacts and vibrations and maintain the long-term stability of the connection. The repeatable tightening and loosening structure allows the user to adjust the tightness of the strap 41 multiple times without affecting the fastening effect and service life of the hose clamp. This design makes the hose clamp more practical in occasions where frequent adjustment or disassembly is required, and at the same time meets the need to adjust the tightening space size according to the actual installation situation.

[0074] Preferably, the tightening and loosening structure of the locking member 42 is a bolt adjustment structure. When tightened, the strap 41 can be locked, and when loosened, the strap 41 can slide relative to the locking member 42 easily. A number of positioning holes that can be clamped by the locking member 42 are provided on the strap 41 to improve the reliability of the locking of the strap 41 by the locking member 42.

[0075] In one embodiment, referring to Figure 2 , the antenna housing 11 is provided with an installation connection hole 112, and the strap 41 passes through the installation connection hole 112 to connect the antenna housing 11.

[0076] The installation connection hole 112 provides a clear installation path for the strap 41. The user only needs to pass the strap 41 through the installation connection hole 112 to achieve connection with the antenna housing 11. Then, the strap 41 is sleeved on the support body 5 and tightened by the locking member 42, and the connection between the antenna 1 and the support body 5 can be completed. This installation method does not require additional fixing parts or tools, greatly simplifies the installation steps, and at the same time this connection method can effectively prevent the antenna housing 11 from shaking or falling off due to external forces, enhancing the stability of the connection.

[0077] Specifically, when setting, multiple installation connection holes 112 can be arranged at intervals, so that connection points can be provided for multiple installation connectors 4, and the antenna 1 can be fixed by using multiple installation connectors 4 to achieve the purpose of improving the reliability of fixation. Of course, only one installation connection hole 112 can also be provided, and only one installation connector 4 is used to fix the antenna 1 to the support body 5.

[0078] In one embodiment, the antenna housing 11 is provided with a winding portion, and the signal line 12 can be wound on the winding portion.

[0079] The winding part is usually designed as one or more convex or concave structures on the antenna housing 11, and its shape and size can be adjusted according to the length and diameter of the signal line 12. When the antenna 1 is removed for recycling, the signal line 12 can be wound around the winding part of the antenna housing 11, and then multiple antennas 1 can be stacked and stored, so as to avoid the problem of multiple signal lines 12 being entangled with each other. In addition, when installing the antenna 1, the user can also wind the excess length of the signal line 12 along the path of the winding part to avoid problems such as the signal line 12 being too long and easily fluttering or tripping the user during use.

[0080] In one embodiment, referring to Figure 7 , the winding part includes two winding bosses 111 spaced apart on the antenna housing 11.

[0081] The winding bosses 111 adopt a convex design to increase the contact area with the signal line 12 and provide a better fixing effect. With two spaced winding bosses 111, when winding, the signal line 12 can be wound around the two winding bosses 111 at the same time, so as to provide a large enough winding space to reduce the number of winding turns and facilitate the user's winding operation.

[0082] Preferably, the aforementioned mounting connection holes 112 are provided on the winding bosses 111.

[0083] In one embodiment, card slots 113 are respectively provided on the opposite sides of the two winding bosses 111.

[0084] Based on the setting of the card slots 113, when winding, the signal line 12 can be stuck in the card slots 113, so as to avoid the signal line 12 detaching from the winding bosses 111 and ensure the stability of the structure after winding.

[0085] In one embodiment, a slot is provided on the antenna housing 11, and the slot is cooperatively provided with the second connector 121, and the second connector 121 can be inserted into the slot for fixation.

[0086] Specifically, after the antenna 1 is recycled and the winding is completed, the second connector 121 at the end of the signal line 12 can be inserted into the slot for fixation, so as to avoid the winding structure from becoming loose.

[0087] Referring to Figure 7 , two second connectors 121 are shown in the figure. One second connector 121 is fixed on the slot and is represented by a dotted line. A second connector 121 is connected to the lower end of the signal line 12. It can be understood that the second connector 121 connected at the slot only shows the insertion state when the second connector 121 is installed. In fact, one antenna 1 is only equipped with one second connector 121, which is connected to one end of the signal line 12 away from the antenna body.

[0088] In one embodiment, the slot is disposed on one of the wire-winding bosses 111.

[0089] By directly disposing the slot on the wire-winding boss 111, the need for additionally forming other fixing holes or slots on the antenna housing 11 is avoided. This design saves space and makes the antenna housing 11 cleaner and more aesthetically pleasing. When a user performs a wire-winding operation, the user can conveniently insert the second connector 121 at the end of the signal wire 12 into the slot located on the wire-winding boss 111. This operation method is both convenient and fast, improving work efficiency.

[0090] In one embodiment, referring to Figure 11 , the antenna housing 11 includes a main housing 114 and a bottom cover 115. An installation opening 1141 allowing the antenna body to be inserted is provided at the bottom of the main housing 114, and the bottom cover 115 covers the installation opening 1141.

[0091] Specifically, providing the main housing 114 with the installation opening 1141 at the bottom facilitates the insertion of the antenna body. Importantly, since the installation opening 1141 faces downward, rainwater is not likely to enter the main housing 114 during rain, thus protecting the antenna body from water. Providing the bottom cover 115 to cover the installation opening 1141 can provide support and protection for the internal antenna body.

[0092] In one embodiment, the bottom cover 115 is provided with a wire-passing hole, and the signal wire 12 extends into the main housing 114 through the wire-passing hole to connect to the antenna body.

[0093] Specifically, providing a wire-passing hole in the bottom cover facilitates the connection of the signal wire, and at the same time, rainwater is not likely to enter the main housing 114 through the wire-passing hole.

[0094] In one embodiment, the support body 5 is a support rod member, and the support rod member stands upright near the valve controller 2 or is connected to the valve controller 2.

[0095] Specifically, when the support rod member stands upright near the valve controller 2, the lower end of the support rod member can be directly inserted into the soil for fixation. When the support rod member is connected to the valve controller 2, structures such as cable ties and hose clamps can be used for fixation.

[0096] The support rod member has an elongated structure. When it is erected, it is easy to support the antenna 1 to a sufficient height, and it is easy to install and fix, facilitating cooperation and connection with the installation connecting member 4.

[0097] In one embodiment, the first connector 21 is a female socket, and the second connector 121 is a male plug.

[0098] Specifically, the first connector 21 is a female socket, which does not need to protrude from the outer surface of the valve controller 2, thus avoiding the problem of being damaged by impact and extrusion from the valve controller 2 during recycling and storage.

[0099] In one embodiment, the electric valve further includes a valve body 3, which includes a valve housing and a valve core installed in the valve housing, and the valve core is connected to the valve controller 2.

[0100] In one embodiment, the antenna 1 is a directional antenna, and the antenna body includes an antenna board and a signal reflection aluminum plate fixed to one side of the antenna board.

[0101] Existing electric valves generally use omnidirectional antennas. An omnidirectional antenna is an antenna 1 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, prone to problems such as signal quality degradation. Generally speaking, existing electric valves using omnidirectional antennas have defects such as poor signal quality, low penetration ability, and poor stability.

[0102] This solution uses a directional antenna, which has the advantages of high gain, good signal quality, strong signal penetration ability, and good signal stability, and can overcome the problems existing in existing electric valves using omnidirectional antennas.

[0103] The use of a directional antenna in an electric valve can also be realized based on the solution of this embodiment. The reason is that the main feature of a directional antenna is that it can 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 conical shape, and the main radiation range is concentrated in the direction pointed by the antenna 1. In other words, the directional antenna has high requirements for the installation direction during application. It can only be installed in the correct direction (such as the direction towards network devices such as servers / relays) to effectively play its communication function. However, the antennas 1 on existing electric valves are fixedly installed, and in many cases, the installation direction of the electric valve is determined by the pipeline layout. This results in that after the electric valve is installed, the orientation of the 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. Therefore, it is inevitable that the directional antennas of some electric valves cannot be correctly oriented towards network devices.

[0104] The antenna 1 of this solution is an external structure, and its installation direction can be freely adjusted according to the actual situation. Therefore, during installation, the direction of the directional antenna can be rotated and adjusted according to the orientation of the network device to ensure that the directional antenna can communicate reliably with the network device.

[0105] In the directional antenna structure, the main function of the signal reflection aluminum plate is to reflect and concentrate electromagnetic wave signals. When the electromagnetic wave signals radiate from the antenna plate, some signals may scatter in all directions, resulting in a weakening of the signal intensity. The signal reflection aluminum plate can reflect these scattered signals back to the antenna plate, thereby enhancing the directivity and gain of Antenna 1. Therefore, the combination of the signal reflection aluminum plate and the antenna plate in this solution can enhance the directivity and gain of Antenna 1 and improve the overall performance of Antenna 1.

[0106] On the other hand, this embodiment provides an electric valve including the above-mentioned external antenna structure.
