Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, and in particular to an intelligent drainage device for agricultural water conservancy projects. Background Technology

[0002] Traditional agricultural drainage relies on manual inspections (such as observing water accumulation in the fields and manually opening and closing sluice gates), which suffers from problems such as "slow response, low accuracy, and high manpower consumption".

[0003] Currently, drainage devices can detect the accumulated water first, and then start the drainage electrically when the water level reaches the required level. Although this is more convenient than manual switches and visual observation, it still requires personnel to pay attention to the water level at all times. It cannot make timely and early warning judgments on the water accumulation and drain the water. In addition, some devices need to be buried in the soil, and due to the large instability of the soil, the installation stability of the device is easily affected. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent drainage device for agricultural water conservancy projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent drainage device for agricultural water conservancy projects, comprising a fixed plate, a detection rod fixedly connected to the center of the bottom end of the fixed plate, multiple humidity sensors equidistantly embedded on one side wall of the detection rod, a cone fixedly connected to the bottom end of the detection rod, multiple flexible metal sheets fixedly connected to the top of the side wall of the cone, and lifting steel wires provided on the front side of each of the multiple flexible metal sheets, a screw rod movably passing through the center of the fixed plate, a battery box installed on one side of the top end of the fixed plate, and a controller box installed on the top end of the battery box; The top of the fixed plate is provided with multiple detection columns, and each detection column has a sliding groove on its front side. A floating block is slidably connected inside the sliding groove. The detection column has an inner groove inside, and a proximity sensor is embedded in the inner wall of the top of the inner groove. A scale is sprayed on one side wall of the detection column.

[0006] As a preferred embodiment of this utility model, the bottoms of the plurality of lifting steel wires are respectively fixedly welded to the bottoms of the outer walls of the plurality of flexible metal sheets, and the tops of the plurality of lifting steel wires are fixedly welded to the bottom end of the screw.

[0007] The above technical solution involves welding a lifting steel wire to the bottom of a flexible metal sheet, which can pull the bottom of the flexible metal sheet up to form a "hook" structure with the soil, increasing soil friction and lateral pressure.

[0008] As a preferred embodiment of this utility model, the bottom thread of the screw penetrates the top of the detection rod, and a cavity is provided inside the detection rod, with one end of the lifting wire located inside the cavity.

[0009] By using the above technical solution, rotating the screw will cause it to rise, which can provide a large pulling force to pull the bottom of the flexible metal sheet up.

[0010] As a preferred technical solution of this utility model, the bottom of the side wall of the detection pole is provided with multiple outlet holes, and the middle part of the multiple lifting steel wires respectively passes through the multiple outlet holes.

[0011] Using the above technical solution, the lifting wire passes through the outlet hole.

[0012] As a preferred embodiment of this utility model, a storage battery is installed inside the battery box, a controller is installed inside the controller box, the storage battery is electrically connected to the controller, and the controller is electrically connected to multiple humidity sensors.

[0013] The controller model is STM32L431RCT6 (ARM Cortex-M4 core), which can be directly connected to the humidity sensor 3 and proximity sensor 16. It can drive the relay module and thus control the drainage actuators such as submersible pumps and electric gates.

[0014] As a preferred technical solution of this utility model, the fixing plate is provided with multiple slots, and the bottoms of the multiple detection columns are respectively inserted into the multiple slots.

[0015] Through the above technical solution, the slot collects and stores multiple detection columns, which can be removed and installed in the required positions during installation.

[0016] As a preferred embodiment of this utility model, the bottom ends of the plurality of detection columns are all fixedly connected with insert plates.

[0017] Using the above technical solution, the insertion plate is inserted into the soil to fix the detection column.

[0018] As a preferred embodiment of this utility model, one end of the floating block is fixedly connected to a sensing block, and the sensing block is slidably connected to the inside of the inner groove.

[0019] The above technical solution uses an ABS engineering plastic (nickel-plated) sensor block to detect water level height and water level rise rate in conjunction with a proximity sensor.

[0020] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting a fixed plate and a detection pole at its bottom, and by embedding multiple humidity sensors at equal intervals, can be inserted into the soil to detect the moisture content of soil layers at different depths, and determine whether it is "too wet" (needs drainage) or "suitable" (no drainage required). The detection data is transmitted to the controller, which then controls whether the drainage execution component is activated. The process does not require frequent human intervention, realizing intelligent detection and drainage of farmland waterlogging. Multiple flexible metal sheets on the outer wall of the cone, along with steel wires and screws, can be stretched after insertion into the soil, causing the bottom of the flexible metal sheets to tilt upwards, thereby increasing the contact force with the soil and improving the stability of the detection pole insertion.

[0021] 2. This utility model uses multiple slots on a fixed plate with internal detection columns. These, along with a floating block and an internal proximity sensor, can be inserted into field drainage ditches, irrigation canals, or low-lying waterlogged areas to monitor water levels. This improves the diversity of drainage monitoring and allows for flexible placement in areas prone to water accumulation, enhancing detection accuracy. Through the cooperation of the sensing block and the proximity sensor, the rising speed and height of the liquid level are monitored, enabling early warning drainage and preventing waterlogging after accumulation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution for an intelligent drainage device for agricultural water conservancy projects:

[0026] Example 1, according to Figure 1 , Figure 4 and Figure 5 As shown, an intelligent drainage device for agricultural water conservancy projects includes a fixed plate 1. A detection pole 2 is fixedly connected to the center of the bottom end of the fixed plate 1. Multiple humidity sensors 3 are equidistantly embedded on one side wall of the detection pole 2. The sensors are made of stainless steel (316L material) and have an ABS shell. The three humidity sensors 3 are located at depths of 0.3m (top soil), 0.6m (middle root layer), and 0.9m (deep root layer), respectively. A cone 19 is fixedly connected to the bottom end of the detection pole 2. Multiple flexible metal sheets 4 are fixedly connected to the top of the side wall of the cone 19. The bottom of the flexible metal sheets 4 is raised to form a "hook" structure with the soil, increasing soil friction and lateral pressure. This can effectively resist the tilting or pulling out of the device caused by strong winds and water flow in the farmland, meeting the requirements for long-term stable operation. Each of the multiple flexible metal sheets 4 is provided with a lifting steel wire 17 on its front side. A screw 9 is movably inserted through the center of the fixed plate 1. A battery box 10 is installed on one side of the top of the fixed plate 1. A controller box 11 is installed on the top of the battery box 10.

[0027] The bottoms of multiple lifting steel wires 17 are fixedly welded to the bottom of the outer wall of multiple flexible metal sheets 4. The flexible metal sheets 4 are corrosion-resistant thin metal sheets with low hardness, and one end can be bent and raised, such as aluminum sheets or copper sheets. The tops of multiple lifting steel wires 17 are fixedly welded to the bottom end of screw 9. Screw 9 is made of No. 45 steel (surface nitrided). The bottom thread of screw 9 passes through the top of the detection rod 2. The detection rod 2 has a cavity inside, and one end of the lifting steel wire 17 is located inside the cavity. Multiple outlet holes 18 are opened at the bottom of the side wall of the detection rod 2. The middle part of multiple lifting steel wires 17 passes through multiple outlet holes 18 respectively. The battery box 10 is equipped with a storage battery. The controller box 11 is equipped with a controller. The controller model is STM32L431RCT6 (ARM Cortex-M4). The core is a microcontroller (MCU) controller with I2C / SPI interface, which can be directly connected to the humidity sensor 3 (such as SHT30) and proximity sensor 16 (such as E2E-X5ME1). It supports GPIO output and can drive relay module to control drainage actuators such as submersible pumps and electric gates. The battery is electrically connected to the controller, and the controller is electrically connected to multiple humidity sensors 3.

[0028] In practical use, this intelligent drainage device for agricultural water conservancy projects allows the operator to remove the detection columns 6 from the multiple slots 12 on the fixing plate 1 and insert them into the soil using the cone 19 at the bottom of the detection rod 2 until the bottom surface of the fixing plate 1 is in contact with the soil surface. This places multiple humidity sensors 3 on the detection rod 2 within the soil, detecting moisture at different depths. When the detection rod 2 is inserted into the soil, the screw 9 can be rotated, causing it to rise. This pulls multiple lifting wires 17 fixed to the bottom of the screw 9, thus pulling the multiple... The bottom of each flexible metal sheet 4 is raised, and the bottom of multiple flexible metal sheets 4 bends and rises, so that the detection pole 2 is stably inserted into the soil for soil moisture monitoring. Soil moisture monitoring data at different depths will be transmitted to the controller at the top. The controller analyzes the moisture data and determines whether it is "too wet" (needs drainage) or "suitable" (no drainage required). The operator can pre-connect the drainage execution components of the agricultural water conservancy project (such as electric gates, solenoid valves, submersible pumps) to the controller. When "drainage is needed" is detected, the drainage execution components will be automatically activated, making it more intelligent.

[0029] Example 2, based on Example 1, such as Figure 1 and Figure 2 , Figure 3 As shown, the top of the fixed plate 1 is provided with multiple detection columns 6, and each detection column 6 has a sliding groove 7 on its front side. A floating block 8 is slidably connected inside the sliding groove 7. The inside of the detection column 6 is provided with an inner groove 14. A proximity sensor 16 is embedded in the inner wall of the top of the inner groove 14. A scale 13 is sprayed on one side wall of the detection column 6. Multiple slots 12 are provided on the fixed plate 1. The bottom of the multiple detection columns 6 is inserted into the multiple slots 12 respectively. The bottom of each of the multiple detection columns 6 is fixedly connected with a plate 5. One end of the floating block 8 is fixedly connected with a sensing block 15. The sensing block 15 is made of ABS engineering plastic (nickel-plated), which is resistant to moisture and corrosion, and is easily detected by the proximity sensor 16. Its cost and processing difficulty are suitable for agricultural equipment scenarios. The sensing block 15 is slidably connected inside the inner groove 14.

[0030] In practical use, this intelligent drainage device for agricultural water conservancy projects monitors soil moisture by removing multiple detection columns 6 and inserting them into field drainage ditches, irrigation canals, or low-lying waterlogged areas using the bottom insert plate 5. This allows for real-time monitoring of water depth (if it exceeds 10cm, it may affect crop root respiration). When the water level rises, it causes the floating block 8 to rise, simultaneously causing the sensing block 15 on the back to rise synchronously. The rising height and speed of the water level are monitored through the interaction of the sensing block 15 and the proximity sensor 16. When the water depth is low, the operator can periodically observe the position of the floating block 8 relative to the scale 13 to monitor the water level in real time, preventing sudden water rises that could soak crops.
