Abstract
Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment technology, and in particular to an automatic irrigation device that can sense the water demand of crops. Background Technology
[0002] The principle of irrigation is that the amount, frequency, and timing of irrigation should be determined based on the water requirements, growth stage, climate, and soil conditions of the medicinal plants. Irrigation should be timely, appropriate, and rational. The main types of irrigation include pre-sowing irrigation, seedling irrigation, growing season irrigation, and winter irrigation.
[0003] Currently, irrigation for potted plants and small greenhouses in homes is still mainly based on manual observation or timer control. Farmers or users must frequently check the soil moisture level, which is not only labor-intensive, but also cannot adjust the water volume according to the real-time water needs of the crops. This often results in insufficient or excessive irrigation, leading to poor plant growth and water waste. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model proposes an automatic irrigation device that can sense the water demand of crops, which facilitates automatic irrigation according to the water demand of crops.
[0005] This utility model provides an automatic irrigation device that can sense the water demand of crops, including a water supply pipe and multiple branch pipes installed on the water supply pipe. A solenoid valve is installed on the branch pipe. A diversion pipe is installed on the side of the branch pipe away from the water supply pipe. Multiple irrigation heads are installed at equal intervals at the bottom of the diversion pipe. A basin rim clamp is installed at the bottom of the junction of the branch pipe and the diversion pipe. A controller is installed on the side wall of the basin rim clamp. The controller is wired to a soil moisture detection rod.
[0006] Using the above technical solution, the soil moisture status is fed back in real time through a soil moisture sensor. Based on the threshold set by the soil sensor, when the soil moisture is lower than the set threshold, the solenoid valve on the corresponding branch pipe is opened to irrigate. When the soil moisture is higher than the threshold, it can be stopped in time to avoid over-irrigation. The design of the diversion pipe allows water to penetrate the soil in the pot evenly, avoiding local over-wetting or drought. The water supply pipe can be connected to multiple branch pipes to automatically irrigate multiple pots of crops. The pot rim clamp makes it easy to integrate and fix the controller, solenoid valve and sensor on the edge of the flower pot, reducing space occupation and making it suitable for compact scenarios such as home potted plants.
[0007] Preferably, the basin rim clamp includes a clamping part and an extension part, the clamping part and the extension part are an integral structure, the controller is located on the side wall of the clamping part, and the solenoid valve and the controller are wired together.
[0008] Using the above technical solution, the clamping part (inverted "U" shape) of the pot rim clamp can firmly clamp the edge of the flower pot, preventing the device from shaking or falling, and the extension part is located on the outside of the flower pot to facilitate the removal of the pot rim clamp.
[0009] Preferably, the clamping part is an inverted "U" shaped plate, the extension part is an inclined plate, the inclined plate is connected to the lower edge of one side of the inverted "U" shaped plate, and the angle between the inclined plate and the inverted "U" shaped plate is between 110° and 160°.
[0010] Preferably, the end of the soil moisture detection rod that is inserted into the soil is conical.
[0011] Using the above technical solution, the conical end reduces resistance, allowing the soil moisture testing rod to be easily inserted into the soil.
[0012] Preferably, the diversion pipe is a notched ring pipe, and both ends of the ring pipe are sealed.
[0013] Using the above technical solution, the notched diversion pipe allows the drip irrigation heads to be distributed around the top of the flowerpot, thus ensuring even water penetration and avoiding localized over-wetting or drought. The notch design also ensures the placement of the plant inside the pot and prevents obstruction by the plant when installing the diversion pipe.
[0014] Preferably, one end of the water supply pipe is provided with a movable connector, the movable connector is connected to a main unit via a flexible hose, the main unit has a built-in water pump, and the pump's pumping end is connected to a water storage tank via a flexible hose.
[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: the soil moisture detection rod provides real-time feedback on the soil moisture status; the threshold set by the soil sensor activates the solenoid valve on the corresponding branch pipe when the soil moisture is lower than the set threshold, and watering is carried out; when the soil moisture is sufficiently higher than the threshold, it can be stopped in time to avoid over-irrigation; the setting of the diversion pipe allows water to permeate the soil in the pot evenly, avoiding local over-wetting or drought; the water supply pipe can be connected to multiple branch pipes, and multiple pots of crops can be automatically watered; the pot rim clamp makes it easy to integrate and fix the controller, solenoid valve, and sensor on the edge of the flower pot, reducing space occupation and making it suitable for compact scenarios such as home potted plants.

[0024] Example 1:
[0025] like Figure 1-3As shown, the present invention proposes an automatic irrigation device that can sense the water demand of crops, including a water supply pipe 1 and multiple branch pipes 2 installed on the water supply pipe. A solenoid valve 3 is installed on the branch pipe 2. A diversion pipe 4 is installed on the side of the branch pipe 2 away from the water supply pipe. Multiple irrigation heads 5 are installed at equal intervals at the bottom of the diversion pipe 4. A basin rim clamp 6 is installed at the bottom of the junction of the branch pipe 2 and the diversion pipe 4. A controller 7 is installed on the side wall of the basin rim clamp 6. The controller 7 is wired to a soil moisture detection rod 8.
[0026] In this embodiment, the other end of the water supply pipe 1 is directly connected to the tap water pipe, and the tap water pipe supplies water directly.
[0027] Using the above technical solution, the soil moisture sensor 8 provides real-time feedback on the soil moisture status. Based on the threshold set by the soil sensor, when the soil moisture is lower than the set threshold, the solenoid valve 3 on the corresponding branch pipe 2 is opened to irrigate. When the soil moisture is higher than the threshold, it can be stopped in time to avoid over-irrigation. The diversion pipe 4 allows water to penetrate the soil in the pot evenly, avoiding local over-wetting or drought. The water supply pipe 1 can be connected to multiple branch pipes 2, which can automatically irrigate multiple pots of crops. The pot rim clamp 6 makes it easy to integrate and fix the controller 7, solenoid valve 3, and sensor on the edge of the flower pot, reducing space occupation and making it suitable for compact scenarios such as home potted plants.
[0028] In this embodiment, the diversion pipe 4 is a ring pipe with a notch, and both ends of the ring pipe are sealed.
[0029] It should be noted that the notched branch pipe 4 allows the drip irrigation heads to be distributed around the top of the flowerpot, thus ensuring even water penetration and preventing localized over-wetting or drought. The notch design also ensures that the plant inside the pot can remain in place, preventing obstruction by the plant when installing the branch pipe 4.
[0030] Please see Figure 3 In this embodiment, the basin edge clamp 6 includes a clamping part 61 and an extension part 62. The clamping part 61 and the extension part 62 are an integral structure. The controller 7 is located on the side wall of the clamping part 61. The solenoid valve 3 and the controller 7 are connected by wires. The clamping part 61 is an inverted "U" shaped plate, and the extension part 62 is an inclined plate. The inclined plate is connected to the lower edge of one side of the inverted "U" shaped plate. The angle between the inclined plate and the inverted "U" shaped plate is between 110° and 160°.
[0031] The clamping part 61 (inverted "U") of the pot rim clamp 6 can firmly clamp the edge of the flower pot to prevent the device from shaking or falling, and the extension part 62 is located on the outside of the flower pot to facilitate the removal of the pot rim clamp 6.
[0032] In this embodiment, the end of the soil moisture sensor 8 that is inserted into the soil is conical.
[0033] The conical end reduces resistance, allowing the soil moisture sensor 8 to be easily inserted into the soil.
[0034] The working principle of the above embodiments:
[0035] Based on the plant species in the flowerpot, a watering threshold is set for the soil moisture sensor 8, which includes a lower threshold and an upper threshold. The soil moisture sensor 8 is then inserted obliquely into the flowerpot, with its bottom end close to the center of the flowerpot. The soil moisture sensor 8 monitors the soil moisture data in real time and transmits it to the controller 7. When the detected soil moisture is lower than the preset lower threshold, the controller 7 immediately opens the solenoid valve 3 on the corresponding branch pipe. Water flows through the water supply pipe 1, branch pipe 2, and the notched annular diversion pipe 4, and drips evenly into the soil from the equidistant irrigation heads 5. When the moisture rises above the preset upper threshold, the controller 7 closes the solenoid valve 3 to stop irrigation. This closed-loop control can prevent soil drought and avoid water waste or localized over-wetting.
[0036] Example 2:
[0037] Based on Example 1, the other end of the water supply pipe 1 is improved so that it does not require an external water pipe. Specifically, please refer to: Figure 4 In this embodiment, a movable connector is provided at one end of the water supply pipe 1. The movable connector is connected to the main unit through a hose. The main unit has a built-in water pump, and the pumping end of the water pump is connected to a water storage tank through a hose.
[0038] It is worth mentioning that the water storage tank and the hose are connected by a flexible connector, which makes it easy to separate the water storage tank and add water.
[0039] It should be noted that the main unit is equipped with a control panel, and multiple controllers 7 and water pumps are electrically connected to the control panel. When the soil moisture sensor 8 in any flower pot detects that the soil moisture is lower than the threshold, the corresponding solenoid valve 3 will be opened, and the water pump will be turned on to pump water. This ensures that water can only be delivered to the flower pot that needs to be watered, thereby achieving the effect of real-time humidity monitoring and automatic watering.
[0040] The working principle of the above embodiment is as follows: the pot rim clamp 6 is clamped on the rim of the flower pot, and the corresponding soil moisture detection rod 8 is inserted into the vicinity of the crop roots in the flower pot. When the soil moisture detection rod 8 detects that the soil moisture of a certain flower pot is less than the threshold, the soil moisture detection rod 8 transmits a signal to the controller 7, and the controller 7 transmits a signal to the control panel to start the water pump to pump water, and at the same time opens the solenoid valve 3 on the corresponding branch pipe 2 of this pot.
[0041] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
