Technical Field

[0001] This application relates to the field of sprinkler irrigation technology, and more particularly to a sprinkler irrigation device. Background Technology

[0002] With the development of modern agricultural technology, sprinkler irrigation devices are increasingly widely used in crop irrigation and plant protection operations. Traditional sprinkler irrigation devices typically only have basic irrigation functions, making it difficult to meet the demands of modern agricultural production for intelligence, precision, and flexibility. For example, most sprinkler irrigation devices adopt a fixed design, have limited functionality, cannot automatically adjust irrigation operations according to the actual usage environment, and lack functional expandability, making modular configuration difficult and limiting the application of sprinkler irrigation devices in diverse agricultural scenarios.

[0003] Existing sprinkler irrigation devices cannot detect rainy conditions, causing them to continue executing irrigation tasks according to a customized schedule even when it is raining, resulting in water waste and over-irrigation. To address these issues, this paper proposes a sprinkler irrigation device that can detect rain and intelligently execute irrigation tasks based on rainfall intensity, saving water and labor and improving the user experience.

[0010] Furthermore, the bottom surface of the groove is inclined, so that the rainwater flows toward the drainage channel.

[0011] Furthermore, at least a portion of the drainage channel is positioned opposite the two electrodes, causing rainwater near the electrodes to flow toward the drainage channel.

[0012] Furthermore, the rainfall sensing component is configured to detect the voltage between the electrodes when the sprinkler device is operating; it also includes a controller configured to control the sprinkler device to stop operating when the voltage is less than a preset threshold.

[0013] Furthermore, the rainfall sensing component is configured as follows:

[0028] The technical solutions in this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] The first embodiment of this application provides a sprinkler irrigation device. For example... Figures 1 to 3 As shown, the sprinkler irrigation device includes a main body 100, a drive unit, and a reservoir 200. The main body 100 includes an inlet 110, an outlet 120, and a channel connecting the inlet 110 and the outlet 120. The drive unit is configured to guide fluid in from the inlet 110 and out from the outlet 120.

[0030] The reservoir 200 is detachably connected to the main body 100 and is used to store medicinal liquid and / or nutrient solution. When the reservoir 200 is connected to the main body 100, it can communicate with a channel, allowing the medicinal liquid and / or nutrient solution in the reservoir 200 to flow into the channel.

[0031] The drive device guides the fluid from the inlet 110 into the channel and the fluid flows out from the outlet 120 to spray the fluid onto the ground to achieve sprinkler irrigation.

[0032] For example, the driving device may include a water pump, whose suction port can be connected to a water source, and whose outlet can be connected to the inlet 110 of the main body 100, to apply power to the water flow, enabling the water to flow from the inlet 110 into the channel 130 and out through the outlet 120. The water pump may also be located at a position between the inlet 110 and the outlet 120. It should be noted that the configuration of the driving device in this embodiment is merely exemplary; the driving device only needs to guide the liquid to flow in from the inlet 110 and out from the outlet 120, and the specific configuration of the driving device is not specifically limited here.

[0033] like Figure 1-3As shown, the sprinkler system includes a main body 100, a drive unit, and a rainfall sensing component 500. The main body 100 includes an inlet 110, an outlet 120, and a channel connecting the inlet 110 and the outlet 120. The drive unit is configured to guide fluid inflow from the inlet 110 and outflow from the outlet 120. The rainfall sensing component 500 is disposed on the outer surface of the main body and is used to sense rainfall.

[0034] In the above embodiment, the rainfall sensing component 500 is connected to the controller of the sprinkler irrigation device. When the rainfall sensing component 500 detects rainfall, the controller can control the sprinkler irrigation device to stop sprinkler irrigation, thus saving water resources.

[0035] The rainfall sensing component 500 includes a resistive rain sensor, a contact immersion sensor, or an optical rain sensor.

[0036] A resistive rain sensor detects the presence of rainwater by measuring changes in voltage. A resistive sensor typically consists of two electrodes. When rainwater replaces the air between the electrodes, the resistance between them changes, resulting in a change in voltage. The sensor's built-in circuitry monitors this voltage change to determine if rainwater has fallen onto the sensor and has conducted electricity between the electrodes.

[0037] Contact immersion sensors typically consist of two or more conductive electrodes placed in areas exposed to rainwater. When water enters the area between the electrodes, the conductivity of the water creates a current between them. The circuitry within the sensor detects this change in current, thus determining whether rainwater has entered the area.

[0038] Optical rain sensors detect the presence of rain by emitting and receiving light. The sensor typically includes a light source (such as an LED) and a light receiver. When rain falls on the sensor surface, the water droplets refract and scatter the light, causing a change in the intensity of the light received by the light receiver. When the light intensity drops below a set threshold, the optical rain sensor determines that rain has fallen.

[0039] It should be noted that the description of the rainfall sensing component 500 in this application is merely exemplary, and is not specifically limited as long as it can achieve rainfall detection.

[0040] By setting up a rainfall sensor component 500, the rainfall detection function of the sprinkler irrigation device can be increased, the intelligence of the sprinkler irrigation device can be improved, and the diversified applications of the sprinkler irrigation device can be increased.

[0041] Furthermore, the rainfall sensing component includes a base 501 and at least two electrodes mounted on the base 501.

[0042] When the rainfall sensing component 500 includes a resistive rain sensor, the rainfall sensing component includes a base 501, which is integrally formed with or detachably connected to the main body of the sprinkler device. In this way, the rainfall sensing component is fixed to the main body. The rainfall sensing component also includes at least two electrodes. The rainfall sensing component detects the voltage between the two electrodes. The controller in the sprinkler device uses the acquired voltage to identify whether water flow is conducted between the two electrodes, thereby knowing whether it is raining and whether the rainfall meets the requirements for stopping sprinkler irrigation, making the control more intelligent.

[0043] Furthermore, the base 501 has a groove 502 configured to collect rainwater.

[0044] Specifically, by configuring a groove 502 on the base 501, rainwater can be collected in the groove 502. By observing the relative positional relationship between the rainwater level in the groove 502 and the electrode, it is easier to detect the amount of rainfall.

[0045] Furthermore, an electrode holder 503 is also provided on the base 501, and the electrode is mounted on the electrode holder 503. The electrode holder 503 is configured such that the position of the electrode is higher than the bottom surface of the groove 502.

[0046] Specifically, by setting an electrode holder 503 on the base 501, the electrodes are mounted on the electrode holder 503, for example, on the top surface of the electrode holder 503. With this arrangement, when there are a small amount of water droplets or light rain, the water level in the base 501 or the groove 502 in the base 501 will not exceed the height of the electrode holder 503, so that there is no water flow between the electrodes on the electrode holder 503. The sprinkler device can still continue to perform the sprinkler irrigation task. That is, through the above design, the sprinkler device will not stop working when the rainfall is small, making the control more user-friendly and intelligent.

[0047] Furthermore, at least a portion of the surface of the groove 502 is provided with a plurality of protrusions 504, which make the rainwater evenly distributed within the groove 502.

[0048] Specifically, by providing multiple raised structures 504, such as square cones, on the surface of the groove 502, when the water mist generated by the machine spraying water is small or the rainfall is relatively light, the water droplets in the groove 502 are punctured by the cones and evenly distributed within the groove 502 before being discharged through the drainage channel 505. Residual water stains are isolated by the electrode seat 503, preventing the electrodes from conducting and maintaining a relatively constant voltage between them, thus avoiding triggering a stop-spraying command. In other embodiments, the multiple raised structures 504 can also be designed as recessed structures, which similarly ensures even distribution of rainwater.

[0049] Furthermore, a drainage channel 505 is provided on one side of the groove 502, and the drainage channel 505 is configured to guide rainwater out.

[0050] Specifically, in order to prevent rainwater from accumulating in the groove 502, a drainage trough 505 is provided on one side of the groove 502. The drainage trough 505 guides the rainwater to flow out. This design can prevent the water level in the groove 502 from rising due to small rainfall over time, which could cause changes in the voltage between the electrodes and result in accidental contact.

[0051] Furthermore, the bottom surface of the groove 502 is inclined, so that the rainwater flows toward the drainage channel 505.

[0052] Specifically, in order to better guide the water flow and ensure that the water can be discharged in a timely manner, the bottom surface of the groove 502 is set at an angle, so that the side of the drainage channel 505 is lower, so that the rainwater in the groove 502 can flow more smoothly to the drainage channel 505.

[0053] Furthermore, at least a portion of the drainage channel 505 is positioned opposite the two electrodes, causing rainwater near the electrodes to flow toward the drainage channel 505.

[0054] Specifically, at least part of the drainage channel 505 is directly opposite the two electrodes. This arrangement prevents rainwater from lingering near the electrodes and allows the water to drain quickly along the drainage channel, preventing water from flowing between the two electrodes due to poor water flow guidance and thus avoiding false triggering.

[0055] Furthermore, the rainfall sensing component 500 is configured to detect the voltage between the electrodes when the sprinkler device is in operation; it also includes a controller configured to control the sprinkler device to stop operating when the voltage is less than a preset threshold.

[0056] Specifically, when the sprinkler system is operating in an outdoor environment, the rainfall sensing component 500 intermittently or continuously detects the voltage value between the electrodes and feeds back the detected voltage value to the controller. When the detected voltage value is less than a preset threshold, the controller issues a command to stop the sprinkler task for the day and repeats the above detection on the second day.

[0057] Furthermore, the rainfall sensing component 500 is configured as follows:

[0058] When the rainwater in the groove 502 does not submerge the electrode holder 503, the voltage is greater than or equal to the preset threshold.

[0059] When the rainwater in the groove 502 submerges the electrode holder 503, the voltage is less than the preset threshold.

[0060] Specifically, when the rainwater in the groove 502 does not submerge the electrode seat 503, the medium between the electrodes is air, which has a high resistance and a high output voltage. At this time, the voltage should be greater than or equal to the preset threshold, so that the sprinkler device will not trigger a shutdown. When the rainwater in the groove 502 submerges the electrode seat 503, the medium between the electrodes is raindrops, which form a parallel resistance path, reducing the resistance between the electrodes and causing the output voltage to drop. At this time, the voltage should be less than the preset threshold, so that the sprinkler device will trigger a shutdown.

[0061] Furthermore, the distance between the two electrodes is in the range of 0.2 to 1 cm.

[0062] Specifically, in some possible embodiments, the inner distance between the two electrodes is set to 0.4 cm and the outer distance between the two electrodes is set to 0.8 cm. This setting makes it easier for the two electrodes to sense the situation of being conducted by rainwater.

[0063] Furthermore, the position of the rainfall sensing component 500 on the main body does not coincide with the irrigation coverage area of ​​the sprinkler device.

[0064] This reduces the amount of liquid sprayed from the sprinkler system hitting the rainfall sensor 500, thus preventing misjudgments of whether rainfall has occurred and improving the detection accuracy of the rainfall sensor 500.

[0065] Furthermore, the position of the rain sensing component 500 on the main body 100 is such that it can be covered by rainwater.

[0066] For example, the rainfall sensor 500 is positioned above the outlet 120, but not within the irrigation range of the sprinkler system. Alternatively, along the water outlet direction of the outlet 120, the rainfall sensor 500 is positioned on the side of the main body 100 opposite to the outlet 120. Alternatively, the outlet 120 can be rotated horizontally to change its horizontal orientation. In this case, the outlet 120 can rotate on a first side between a first position and a second position, and the rainfall sensor 500 is positioned on a second side between the first and second positions. The first side and the second side are opposite to each other.

[0067] Furthermore, to adapt to long-term outdoor environments, the electrodes are made of corrosion-resistant metal materials, and the base 501 is made of aging-resistant plastic.

[0068] This invention uses a rainfall sensing component 500 to detect rainy days. For light rainfall or short-duration rain, the water level accumulated in the groove is insufficient to trigger the two electrodes to conduct, and the voltage between the electrodes remains essentially unchanged, without triggering a stop to irrigation. However, during moderate to heavy rain, there is a continuous water flow in the groove 502 that is higher than the electrode base 503, causing the electrodes to conduct and the voltage value to remain below the detection threshold. This triggers the controller to stop the irrigation. In addition, the controller can also prompt the user to stop irrigation.
