Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a water-saving and water-controlling irrigation device. Background Technology

[0002] Irrigation is essential for agricultural planting and animal husbandry to maintain soil moisture and nourish crops. It's a technical measure to replenish the water needed by crops. To ensure normal crop growth and achieve high and stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or uneven rainfall often fails to meet the water requirements of crops. Therefore, artificial irrigation is necessary to compensate for the lack of natural rainfall. With increasingly scarce water resources, the need for water conservation and control in agricultural irrigation and various landscape irrigation processes is becoming increasingly urgent. Irrigation equipment must be used to conserve and control water to improve water resource utilization efficiency.

[0003] However, existing irrigation equipment usually relies on human judgment of soil moisture and experience to determine the amount of water to be used during irrigation. This makes it difficult to accurately control the amount of water used based on soil moisture, which can easily lead to a large waste of water resources and is not conducive to water conservation. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a water-saving and water-controlling irrigation device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a water-saving and water-controlled irrigation device, including an irrigation water delivery pipe connected to a water source. One end of the irrigation water delivery pipe is equipped with a water pump located inside the water source to provide power for irrigation water delivery. A water pressure sensor is installed at the outlet of the water pump to detect the pressure inside the irrigation water delivery pipe and control the automatic start and stop of the water pump. One end of the irrigation water delivery pipe is fixedly installed with a water outlet bracket for controlling the irrigation position. The bottom of the water outlet bracket is fixedly installed with a telescopically adjustable detection rod. A laser rangefinder sensor for detecting the position of the detection rod is fixedly installed inside the detection rod. The laser rangefinder sensor is signal-connected to a microprocessor for automated management. The microprocessor is signal-connected to a soil moisture sensor for detecting soil moisture and a water flow sensor for detecting irrigation water consumption. A guide frame for guiding the irrigation water delivery pipe is fixedly installed inside the water outlet bracket. A locking block for positioning the guide frame is fixedly installed inside the guide frame.

[0006] Preferably, in any of the above embodiments, the water outlet bracket includes a movable base, a synchronous pneumatic rod controlled by a pneumatic system via a microprocessor signal connection, and an irrigation fixed seat for lifting and lowering. The bottom of the movable base is provided with travel wheels, and the four corners of the top of the movable base are fixedly installed with synchronously moving pneumatic rods. The top of the synchronous pneumatic rods is fixedly installed with the irrigation fixed seat.

[0007] The above technical solution is adopted: a polyurethane travel wheel is installed at the bottom of the mobile base for easy movement; a synchronous pneumatic rod (double-acting cylinder, one set operating synchronously, connected to the microprocessor via a solenoid valve signal) is used; the travel wheel of the mobile base facilitates the movement of the equipment in the field; the braking function can fix the position during irrigation to prevent slippage and irrigation misalignment; the synchronous design of the pneumatic rods ensures smooth lifting and lowering of the irrigation fixing seat; it can be adjusted according to the crop height to avoid the water outlet being too close to the crop, which would damage the root system, or too far away, which would waste water resources; the aluminum alloy material of the irrigation fixing seat is lightweight and rigid, which can stably fix the irrigation water pipe and the water outlet to prevent pipe vibration.

[0008] Preferably, in any of the above embodiments, the irrigation water supply pipe passes through the irrigation fixing base and has an outlet head fixedly installed at one end above the irrigation fixing base. The water flow sensor is fixedly installed inside the outlet head, and the outlet head has an outlet control valve that is signal-connected to the microprocessor.

[0009] The above technical solution employs an irrigation water delivery pipe (the pipe length is designed according to the irrigation area) as the water source delivery channel. One end is connected to a centrifugal pump at the water source via a flange (the sealing gasket is made of EPDM rubber), and the other end passes through the irrigation mounting base of the outlet bracket. A water outlet head (made of copper, with drip or sprinkler irrigation as the water outlet method) is installed at the end. A water pressure sensor (connected to a microprocessor signal) is also connected in series on the pipe to monitor the pipe pressure in real time. A water flow sensor (outputting a pulse signal and connected to the microprocessor signal) is fixedly installed inside the water outlet head above the irrigation mounting base. The turbine blades are located in the center of the water flow channel; the water flow impacts the blades, causing them to rotate and generating a pulse signal. The irrigation water delivery pipe is made of lightweight and easy-to-lay material, and its large diameter design ensures sufficient water flow to meet the irrigation needs of small and medium-sized farmlands. The water pressure sensor detects the pressure inside the pipe; when the pressure is too low, it triggers the centrifugal pump to start and replenish the pressure; when the pressure is too high, it controls the pump to stop to prevent pipe bursting. The adjustable water outlet head can adapt to different crops (e.g., drip irrigation for vegetables, sprinkler irrigation for lawns), improving irrigation adaptability.

[0010] Preferably, in any of the above embodiments, the detection support rod includes an electric telescopic rod connected to a microprocessor signal and an insertion rod with a cone-shaped bottom. One end of the top of the movable base is provided with a control box with a built-in battery. The microprocessor is located inside the control box and connected to the battery. The electric telescopic rod is fixedly installed inside the control box, and one end of the electric telescopic rod is fixedly installed with an insertion rod that moves up and down inside the control box.

[0011] The above technical solution employs the following: the insertion rod has an internal mounting slot for accommodating a soil moisture sensor; the electric telescopic rod is fixed inside the control box on top of the mobile base; the insertion rod is fixed to the output end of the telescopic rod and can rise and fall with it; the adjustable stroke of the electric telescopic rod can adapt to the root depth of different crops; the positioning accuracy ensures the insertion rod depth accuracy and improves detection accuracy; the conical structure of the insertion rod reduces soil insertion resistance, facilitating single-person operation; the galvanized layer enhances resistance to soil corrosion; and the battery in the control box provides power, adapting to field scenarios without external power supply.

[0012] Preferably, in any of the above embodiments, the laser rangefinder is fixedly installed at the top of the insertion rod and located on one side of the electric telescopic rod, and the soil moisture sensor is fixedly installed inside the insertion rod.

[0013] The above technical solution employs the following: A laser rangefinder (infrared type, connected to the microprocessor via bus signal) is fixedly installed at the top of the insertion rod, located on one side of the electric telescopic rod, with its detection end facing the top surface of the control box of the moving base (serving as a reference surface). It measures the lifting distance of the insertion rod in real time, indirectly obtaining the soil insertion depth. A soil moisture sensor (capacitive type, connected to the microprocessor signal) is fixedly installed in the mounting groove inside the insertion rod, with its detection end exposed on the side wall of the insertion rod, in direct contact with the soil. High-precision detection can accurately reflect the insertion depth of the insertion rod, ensuring that the soil moisture sensor is at the preset detection depth, avoiding moisture detection errors caused by improper depth. The high sampling frequency can dynamically monitor the insertion process and promptly detect insertion abnormalities. The small size design allows it to be integrated into the top of the insertion rod without affecting the insertion of the rod into the soil.

[0014] Preferably, in any of the above embodiments, the guide frame includes a guide rail for support and guidance and a sliding seat for guiding the irrigation water pipe. The guide rail is fixedly installed on the top of the movable base, and the sliding seat, which is fitted onto the surface of the irrigation water pipe, is slidably connected inside the guide rail.

[0015] The above technical solution is adopted as follows: the guide rail is fixed to the top of the movable base by bolts, and the sliding seat is slidably connected to the rail, which can move along the length of the rail. The aluminum alloy profile of the guide rail is rigid and can support the weight of the irrigation water pipe, preventing the water pipe from sagging. The silicone pad of the sliding seat can increase the friction with the water pipe, fix the position of the water pipe, and at the same time avoid hard contact that could cause wear on the water pipe. The sliding fit allows the sliding seat to adjust its position synchronously with the extension and retraction of the irrigation water pipe or the movement of the outlet bracket, preventing the water pipe from bending and extending its service life.

[0016] Preferably, in any of the above embodiments, the locking block includes a fastening spring that provides supporting force and a locking block for engaging and locking. The fastening spring is fixedly installed inside the sliding seat, and a locking block that moves inside the sliding seat is fixedly installed at one end of the fastening spring. A pull rod that passes through the fastening spring and the sliding seat is provided at one end of the locking block.

[0017] The above technical solution is as follows: a fastening spring is fixedly installed in the spring groove inside the sliding seat, and a locking block is fixed to one end of the spring and can slide along the spring groove. A pull rod (made of plastic with a pull ring at the end) is also fixed to one end of the locking block, passing through the fastening spring and the sliding seat. The guide rail has positioning holes (distributed along the length of the rail) that match the locking block. The elastic force of the fastening spring pushes the locking block into the positioning hole of the guide rail, locking the position of the sliding seat and preventing the sliding seat from moving due to water pipe vibration or wind during irrigation. The chamfered design of the locking block makes it easy for the locking block to automatically disengage from the positioning hole when the sliding seat moves, without the need for manual unlocking. The pull rod is easy to manually pull to unlock, realizing quick adjustment of the sliding seat. The galvanized layer enhances the corrosion resistance of the locking block.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. An adjustable detection rod is installed inside the irrigation equipment to fix the soil moisture sensor. During irrigation, the detection rod can be raised or lowered according to the type of crop being irrigated. Based on the data feedback from the laser rangefinder sensor, the detection rod can be inserted into the soil at different depths to detect the soil moisture of different crops. The water consumption of the irrigation pipe is monitored and controlled based on the detected moisture information and the data from the water flow sensor, which facilitates more precise control of irrigation water consumption, improves the accuracy of water conservation and control, and helps to save water resources.

[0019] 2. An adjustable guide frame is installed inside the water outlet support to move the bend in the irrigation water pipe, so that the irrigation water pipe can be adjusted with the water outlet support, which improves the stability and convenience of adjusting the irrigation water pipe.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-5As shown, an embodiment of the present invention provides a water-saving and water-controlled irrigation device, including an irrigation water delivery pipe 1 connected to a water source. One end of the irrigation water delivery pipe 1 is equipped with a water pump located inside the water source to provide power for irrigation water delivery. A water pressure sensor is installed at the outlet of the water pump to detect the pressure inside the irrigation water delivery pipe 1 and control the automatic start and stop of the water pump. One end of the irrigation water delivery pipe 1 is fixedly installed with a water outlet bracket 2 to control the irrigation position. The bottom of the water outlet bracket 2 is fixedly installed with a telescopically adjustable detection rod 3. Inside the detection rod 3 is a laser rangefinder sensor 4 for detecting its position. The laser rangefinder sensor 4 is signal-connected to a microprocessor for automated management. The microprocessor is signal-connected to a soil moisture sensor 5 for detecting soil moisture and a water flow sensor 6 for detecting irrigation water consumption. Inside the water outlet bracket 2 is a guide frame 7 for guiding the irrigation water delivery pipe 1. Inside the guide frame 7 is a locking block 8 for positioning it.

[0024] Preferably, the water outlet bracket 2 includes a movable base 21, a synchronous pneumatic rod 22 controlled by a pneumatic system via a microprocessor signal connection, and an irrigation fixed seat 23 that can be raised and lowered. The bottom of the movable base 21 is provided with travel wheels, and the four corners of the top of the movable base 21 are fixedly installed with synchronously moving synchronous pneumatic rods 22. The top of the synchronous pneumatic rods 22 is fixedly installed with the irrigation fixed seat 23.

[0025] The above technical solution is adopted: four polyurethane wheels are installed at the bottom of the mobile base 21 for easy movement; the synchronous pneumatic rods 22 (double-acting cylinders, four in a group, operating synchronously, connected to the microprocessor via solenoid valve signals) facilitate the movement of the equipment in the field; the braking function can fix the position during irrigation to prevent slippage and irrigation misalignment; the four-group synchronous design of the synchronous pneumatic rods 22 ensures that the irrigation fixing seat 23 rises and falls smoothly; it can be adjusted according to the crop height to avoid the water outlet being too close to the crop, which would damage the root system, or too far away, which would waste water resources; the aluminum alloy material of the irrigation fixing seat 23 is lightweight and rigid, which can stably fix the irrigation water pipe 1 and the water outlet to prevent pipe vibration.

[0026] The movable base 21 is based on the principle of rolling friction, and the low coefficient of friction of the polyurethane wheels enables effortless movement. The brake fixes the position through the friction between the brake pads and the wheel rim. The synchronous pneumatic rod 22 is based on Pascal's principle, and compressed air drives the piston rod to extend and retract. Four cylinders ensure synchronous action through a flow divider valve. The irrigation fixing seat 23 is based on the principle of frame support, and the pipe body is fixed by the interference fit between the mounting holes and the water pipe. The anodized layer enhances corrosion resistance. When the irrigation position needs to be adjusted, the brake of the movable base 21 is released, the bracket is pushed to the target area, and the brake is depressed to fix it. According to the crop height, the microprocessor controls the solenoid valve of the synchronous pneumatic rod 22 to open. When activated, compressed air enters the cylinder, and the piston rod extends, causing the irrigation mounting base 23 to rise. If a lowering is required, the solenoid valve is switched, the cylinder exhausts air, and the mounting base descends under gravity. During irrigation, the synchronous pneumatic rod maintains pressure to keep the mounting base stable. When moving, the mounting base is lowered to its lowest position to reduce center of gravity shift and prevent tipping. The microprocessor detects the height of the irrigation mounting base 23 through a displacement sensor and presets a height threshold based on the crop type. If the height deviation exceeds the threshold, the pneumatic rod extension is adjusted, and overload protection is set for the pneumatic rod to prevent cylinder damage. The travel wheel bearings are lubricated regularly, and the pneumatic rod seals are checked.

[0027] Preferably, in any of the above schemes, the irrigation water supply pipe 1 passes through the irrigation fixing seat 23 and is provided with an outlet head fixedly installed at one end above the irrigation fixing seat 23. The water flow sensor 6 is fixedly installed inside the outlet head, and the outlet head is provided with an outlet control valve that is connected to the microprocessor signal.

[0028] The above technical solution is adopted as follows: Irrigation water delivery pipe 1 (the pipe length is designed according to the irrigation area) serves as the water source transportation channel. One end is connected to the centrifugal pump at the water source through a flange (the sealing gasket is made of EPDM rubber), and the other end passes through the irrigation fixing seat 23 of the water outlet bracket 2. A water outlet head (made of copper, with water outlet method of drip irrigation or sprinkler irrigation) is installed at the end. A water pressure sensor (connected to the microprocessor signal) is also connected in series on the pipeline to monitor the pressure in the pipe in real time. A water flow sensor 6 (outputting a pulse signal and connected to the microprocessor signal) is fixedly installed on the irrigation fixing seat 2. Inside the water outlet at the top (3), the turbine blades are located in the center of the water flow channel. The water flow impacts the blades, causing them to rotate and generate a pulse signal. The irrigation water pipe (1) is made of lightweight and easy-to-lay material. Its large-diameter design ensures sufficient water flow to meet the irrigation needs of small and medium-sized farmlands. The water pressure sensor can detect the pressure inside the pipe. When the pressure is too low, it triggers the centrifugal pump to start and replenish the pressure. When the pressure is too high, it controls the pump to stop to prevent the pipe from bursting. The adjustable water outlet mode can be adapted to different crops (such as drip irrigation for vegetables and sprinkler irrigation for lawns), improving irrigation adaptability.

[0029] Based on the principles of fluid statics and dynamics, a centrifugal pump pressurizes water from a source (such as well water or a reservoir) and delivers it to the outlet through a rigid pipe in irrigation water delivery pipe 1. Water flow is achieved using the pressure difference within the pipe. A water pressure sensor converts the pipe pressure into an electrical signal through the piezoresistive effect, transmitting it to a microprocessor for pressure monitoring. Before irrigation, the microprocessor controls the centrifugal pump to start. The source water is pressurized by the pump and enters irrigation water delivery pipe 1. The water pressure sensor provides real-time feedback on the pipe pressure. If the pressure is stable, water is delivered along the pipe to the outlet. Depending on crop needs, the outlet can be manually adjusted to drip irrigation or sprinkler irrigation mode. During irrigation, if the pipe pressure drops, the microprocessor controls the pump to increase its power to compensate. If the pressure exceeds a threshold, the pump immediately stops and an alarm sounds. After irrigation, the centrifugal pump is turned off, and residual water in the pipe is drained through the outlet. The microprocessor presets a water pressure threshold and uses a PID algorithm to control the centrifugal pump speed to maintain stable pipe pressure. A pipe leak detection system is implemented, triggering an audible and visual alarm upon leak. The pipes are periodically subjected to pressure tests.

[0030] Preferably, in any of the above schemes, the detection support rod 3 includes an electric telescopic rod 31 connected to a microprocessor signal and an insertion rod 32 with a cone-shaped bottom. One end of the top of the movable base 21 is provided with a control box with a built-in battery. The microprocessor is located inside the control box and connected to the battery. The electric telescopic rod 31 is fixedly installed inside the control box, and one end of the electric telescopic rod 31 is fixedly installed with the insertion rod 32, which moves up and down inside the control box.

[0031] The above technical solution is adopted: the insertion rod 32 has an internal mounting slot for accommodating the soil moisture sensor 5; the electric telescopic rod 31 is fixed in the control box on the top of the movable base 21; the insertion rod 32 is fixed to the output end of the telescopic rod and can be raised and lowered with the telescopic rod; the adjustable stroke of the electric telescopic rod 31 can adapt to the root depth of different crops; the positioning accuracy ensures the depth accuracy of the insertion rod 32 and improves the detection accuracy; the conical structure of the insertion rod 32 reduces the resistance to insertion into the soil and facilitates single-person operation; the galvanized layer enhances the resistance to soil corrosion; and the battery in the control box can provide power and is suitable for field scenarios without external power supply.

[0032] The electric telescopic pole 31 is based on the screw drive principle. The motor drives the screw to rotate, converting the rotational motion into linear motion, which pushes the insertion rod 32 up and down. The conical structure of the insertion rod 32 is based on the principle of tip force, which increases pressure by reducing the contact area, making it easy to insert into the soil. The battery converts chemical energy into electrical energy to power the telescopic pole and the sensor. Before detection, the microprocessor controls the electric telescopic pole 31 to extend according to the crop type, which drives the insertion rod 32 to move downward. After the bottom of the cone contacts the soil, it continues to insert until the laser rangefinder 4 detects that the depth has reached the preset level. During the insertion process, if a hard soil clod is encountered, the microprocessor controls the telescopic pole to pause for 1 second and then retract in the opposite direction before inserting in the forward direction to avoid bending the pole. After the detection is completed, the telescopic pole is controlled to retract, and the insertion rod 32 is pulled out of the soil. The residual soil on the surface falls off naturally through the conical slope. The microprocessor has a built-in crop-depth correspondence database. After the user selects the crop type, the preset depth is automatically called. The current sensor monitors the working current of the electric telescopic pole 31. If the current is overloaded, the machine will stop immediately and an alarm will sound. The stroke accuracy of the telescopic pole is calibrated regularly, and the deviation is adjusted by standard gauge blocks to ensure positioning accuracy.

[0033] Preferably, of any of the above solutions, the laser rangefinder 4 is fixedly installed at the top of the insertion rod 32 and located on one side of the electric telescopic rod 31, and the soil moisture sensor 5 is fixedly installed inside the insertion rod 32.

[0034] The above technical solution is adopted as follows: the laser rangefinder 4 (infrared type, connected to the microprocessor via bus signal) is fixedly installed at the top of the insertion rod 32, located on one side of the electric telescopic rod 31, with the detection end facing the top surface of the control box of the moving base 21 (as a reference surface), to measure the lifting distance of the insertion rod 32 in real time and indirectly obtain the soil insertion depth. The soil moisture sensor 5 (capacitive type, connected to the microprocessor signal) is fixedly installed in the mounting groove inside the insertion rod 32, with the detection end exposed on the side wall of the insertion rod and in direct contact with the soil. The high-precision detection can accurately reflect the insertion depth of the insertion rod 32, ensuring that the soil moisture sensor 5 is at the preset detection depth and avoiding moisture detection errors caused by improper depth. The high sampling frequency can dynamically monitor the insertion process and detect insertion abnormalities in a timely manner. The small size design can be integrated into the top of the insertion rod without affecting the insertion of the rod into the soil.

[0035] Based on the time-of-flight principle, the sensor emits modulated infrared light. The light signal is reflected by the top surface of the control box and detected by the receiver. By calculating the round-trip time of the light signal, the distance between the top of the insertion rod 32 and the reference plane is obtained. Combined with the initial distance (the distance when the telescopic rod is fully retracted), the insertion depth is calculated. The soil moisture sensor 5 is based on the principle of soil dielectric constant variation. When the soil moisture is different, the dielectric constant is different, and the sensor's capacitance value changes with the dielectric constant. By detecting the change in capacitance value, it is converted into soil volumetric water content. Then, the analog signal is converted into a digital signal by an AD converter and transmitted to the microprocessor. When the electric telescopic rod 31 drives the insertion rod 32 to descend, the laser rangefinder 4 continuously emits infrared light to detect the insertion rod. The distance between the top and the top surface of the control box is received in real time by the microprocessor. When the insertion depth reaches the preset value, the microprocessor controls the telescopic rod to stop descending. If the distance data does not change within 10 seconds during insertion, it is determined that the insertion is obstructed. The telescopic rod is then paused and a "clear obstacle" prompt is issued. When the insertion rod is pulled out, the sensor continues to detect distance changes until the initial distance is restored, indicating that the rod has been completely pulled out. The microprocessor filters the sensor data to remove distance noise caused by soil vibration and sets a depth deviation threshold. When the threshold is exceeded, the extension amount of the electric telescopic rod is adjusted. The sensor is calibrated periodically with a standard rangefinder to ensure detection accuracy. When the sensor is working, the microprocessor controls it to be in a low-power mode to extend the battery life.

[0036] Preferably, the guide frame 7 includes a guide rail 71 for support and guidance and a sliding seat 72 for guiding the irrigation water pipe 1. The guide rail 71 is fixedly installed on the top of the movable base 21, and the sliding seat 72, which is fitted onto the surface of the irrigation water pipe 1, is slidably connected inside the guide rail 71.

[0037] The above technical solution is adopted: the guide rail 71 is fixed to the top of the movable base 21 by bolts, and the sliding seat 72 is slidably connected to the rail and can move along the length of the rail. The aluminum alloy profile of the guide rail 71 is rigid and can support the weight of the irrigation water pipe 1, preventing the water pipe from sagging. The silicone pad of the sliding seat 72 can increase the friction with the water pipe, fix the position of the water pipe, and at the same time avoid hard contact that could cause wear on the water pipe. The sliding fit allows the sliding seat to adjust its position synchronously with the extension and retraction of the irrigation water pipe 1 or the movement of the water outlet bracket 2, preventing the water pipe from bending and extending its service life.

[0038] Based on the principle of sliding friction guidance, the sliding seat 72 slides along the groove of the guide rail 71. The rail restricts the lateral displacement of the sliding seat, ensuring linear movement. The elastic deformation of the silicone pad can fill the gap between the water pipe and the through hole, achieving flexible fixation and buffering water pipe vibration. When the water outlet bracket 2 moves, the irrigation water pipe 1 moves with the bracket, causing the sliding seat 72 to slide along the guide rail 71, preventing excessive bending of the water pipe between the bracket and the water source. When the synchronous pneumatic rod 22 drives the irrigation fixing seat 23 to rise and fall, the water pipe moves up and down, and the sliding seat slides along the water pipe. The guide rail is finely adjusted to maintain the natural state of the water pipe. If manual adjustment of the irrigation range is required, the sliding seat can be pushed along the guide rail to adjust the water outlet position. After use, the sliding seat should be moved to the middle of the guide rail to relax the water pipe and prevent deformation caused by long-term stretching. The movement of the sliding seat 72 can be operated manually or assisted by the micro-push rods at both ends of the guide rail controlled by the microprocessor. It is suitable for remote control scenarios. The groove of the guide rail 71 should be cleaned regularly, and silicone grease should be applied to ensure sliding resistance. The wear of the silicone pad should be checked to prevent the water pipe from loosening.

[0039] Preferably, in any of the above embodiments, the locking block 8 includes a fastening spring 81 that provides supporting force and a locking block 82 for engaging and locking. The fastening spring 81 is fixedly installed inside the sliding seat 72, and a locking block 82 that moves inside the sliding seat 72 is fixedly installed at one end of the fastening spring 81. A pull rod that passes through the fastening spring 81 and the sliding seat 72 is provided at one end of the locking block 82.

[0040] The above technical solution is adopted as follows: the fastening spring 81 is fixedly installed in the spring groove inside the sliding seat 72, the locking block 82 is fixed to one end of the spring and can slide along the spring groove, and a pull rod (made of plastic with a pull ring at the end) is also fixed at one end of the locking block, which passes through the fastening spring 81 and the sliding seat 72. The guide rail 71 has positioning holes (distributed along the length of the rail) that are compatible with the locking block 82 on the side wall of the groove. The elastic force of the fastening spring 81 pushes the locking block 82 into the positioning hole of the guide rail 71, locking the position of the sliding seat 72 and preventing the sliding seat from moving due to water pipe vibration or wind during irrigation. The chamfered design of the locking block 82 makes it easy for the locking block to automatically disengage from the positioning hole when the sliding seat moves, without the need for manual unlocking. The pull rod is easy to manually pull to unlock, realizing quick adjustment of the sliding seat. The galvanized layer enhances the corrosion resistance of the locking block.

[0041] Based on the principle of spring elastic return, when the sliding seat 72 moves, the chamfered surface of the locking block 82 contacts the edge of the positioning hole, compressing the fastening spring 81 and disengaging from the positioning hole. When it moves to the target positioning hole, the spring returns to its original position, pushing the locking block into the hole to achieve positioning. When manually unlocking, the pulling rod drives the locking block to compress the spring and disengage from the positioning hole, allowing the sliding seat to move freely. When the sliding seat 72 moves along the guide rail 71, the locking block 82 alternately disengages and engages between the positioning holes, producing a "click" sound to indicate a change in position and reaching the target position (such as the water outlet). After aligning with the crop ridge, the locking block engages in the positioning hole, locking the sliding seat. If a fine adjustment is needed, push the sliding seat, and the locking block will automatically disengage from the current positioning hole and engage in the adjacent hole. If a large movement is needed, manually pull the pull rod to compress the fastening spring, disengaging the locking block from the positioning hole, allowing the sliding seat to slide freely. Once in position, release the pull rod, and the locking block will automatically engage. After long-term use, if the spring tension is insufficient, the fastening spring can be replaced. The locking force of the locking block 82 can be tested with a tension gauge; if the tension is insufficient, the spring can be replaced. The pull ring design of the pull rod facilitates operation and prevents slippage.

[0042] The working principle of this water-saving and water-controlling irrigation device is as follows: First, the device is pushed to the target irrigation area by the travel wheels at the bottom of the movable base 21. The brake is pressed to fix the position. The battery in the control box powers the components. After the microprocessor starts, it first controls the electric telescopic rod 31 of the detection support rod 3 to extend, which drives the insertion rod 32 with a cone-shaped structure at the bottom to move towards the soil. The laser range sensor 4 at the top of the insertion rod detects the insertion depth in real time and feeds the data back to the microprocessor. When the depth reaches the preset value corresponding to the crop, the electric telescopic rod stops moving. The soil moisture sensor 5 inside the insertion rod contacts the soil and detects the soil moisture. If the moisture is lower than the suitable threshold for the crop, the microprocessor triggers the irrigation process: on the one hand, it controls the synchronous pneumatic rod 22 of the water outlet bracket 2 to extend and retract, which drives the irrigation fixed seat 23 to rise and fall to the target height to avoid damaging the root system. On the other hand, it pushes the sliding seat 72 of the guide movable frame 7 to move along the guide slide rail 71, which drives the irrigation water delivery pipe 1 to adjust the position of the water outlet head. The fastening spring 81 of the locking block 8 pushes the locking block 82 to lock into the positioning hole of the slide rail to fix the sliding seat. Subsequently, the microprocessor controls the centrifugal pump at the water source to start, the irrigation water supply pipe 1 delivers water, the water pressure sensor inside the pipe monitors the pressure, the water outlet control valve of the water outlet head opens, the water flow sensor 6 measures the water consumption in real time, during irrigation, the soil moisture sensor continuously provides feedback data, when the moisture rises to a suitable value or the water volume reaches a preset value, the microprocessor immediately shuts off the control valve and the centrifugal pump, after irrigation is completed, the electric telescopic rod retracts and pulls out the insertion rod, and the synchronous pneumatic rod drives the irrigation fixing seat to the lowest position, all the structures work together to achieve precise water-saving irrigation.
