Description

Technical Field

[0001] This invention relates to the field of water resources monitoring technology, specifically to a water resources monitoring device and method for irrigation. Background Technology

[0002] Water resources are the core element of agricultural irrigation systems. The quality and stability of water directly affect crop growth and development, the lifespan of irrigation systems, and agricultural production efficiency. With the development of modern agriculture towards large-scale and precision, the demand for dynamic monitoring of irrigation water resources is becoming increasingly urgent. By sampling and monitoring the water quality of irrigation sources and irrigation nodes in the fields, key parameters such as nutrient content, impurity content, and pollutant indicators in the water can be obtained in a timely manner, providing data support for optimizing irrigation plans, rationally allocating water resources, and protecting farmland ecology.

[0003] Currently, water resource monitoring devices used in the irrigation sector generally suffer from low efficiency and insufficient monitoring accuracy in the water sampling process. Existing sampling devices are mostly single-sampling structures, capable of collecting only one set of water samples per operation. To collect samples at different depths and monitoring points, the sampling component must be lowered multiple times. This not only increases the complexity of the operation process and prolongs the monitoring cycle, but also makes it prone to poor data repeatability due to environmental interference and deviations in sampling depth control during multiple sampling processes, hindering accurate comparative analysis of multiple sets of water samples. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water resource monitoring device and method for irrigation, in order to achieve the aforementioned objectives.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water resource monitoring device for irrigation, comprising: a monitoring frame, wherein a winding assembly is fixedly connected to the upper end of one side of the monitoring frame, a traction rope is wound around the outer side wall of the winding assembly, and a sampling assembly is provided at the lower end of the traction rope;

[0006] The sampling assembly includes a sampling cylinder, with four sampling bottles fixedly connected to the inner wall of the sampling cylinder. The four sampling bottles are arranged in a circular array. Four water inlets are fixedly connected to the upper end of the sampling cylinder. Filter components are provided on the inner walls of the water inlets, and the four water inlets are respectively connected to the four sampling cylinders. A protective shell is fixedly connected to the upper end of the sampling cylinder. A turntable is fixedly connected to the inner wall of the protective shell. A connecting rod is fixedly connected to the outer wall of the turntable. A ring is fixedly connected to one end of the connecting rod, located on the outer wall of the turntable. A protrusion one and a protrusion two are fixedly connected to the outer wall of the turntable and the inner wall of the ring, respectively. Four guide grooves are fixedly connected to the inner wall of the protective shell. Sliding rods are slidably connected to the inner walls of the four guide grooves. Stops are fixedly connected to the upper ends of the four sliding rods.

[0007] Preferably, the upper end of the sampling tube and both sides of the water inlet are fixedly connected to slide rails, and a cover plate is slidably connected between the two slide rails.

[0008] Preferably, the sampling assembly further includes a rotating rod one and a rotating rod two rotatably connected to the inner wall of the sampling cylinder. A half-tooth gear is fixedly connected to the outer wall of the rotating rod one, and a driven gear is fixedly connected to the outer wall of the rotating rod two. The driven gear meshes with the half-tooth gear. A frame is fixedly connected to the inner wall of the sampling cylinder, and a motor is fixedly connected to the lower end of the frame. The output end of the motor is fixedly connected to the rotating rod one.

[0009] Preferably, the filter assembly includes a filter frame, a baffle mesh is fixedly connected to the inner wall of the filter frame, grooves are formed on both sides of the filter frame, a limit block is slidably connected to the inner wall of the groove, a spring is fixedly connected to one side of the limit block, the end of the spring away from the limit block is connected to the inner wall of the groove, two sliding grooves are formed at the upper end of the filter frame, and the two sliding grooves are respectively connected to two grooves, a slider is slidably connected to the inner wall of the sliding groove, and one end of the slider is fixedly connected to the limit block.

[0010] Preferably, the filter frame is adapted to the inner wall of the water inlet, and the inner wall of the water inlet has two limiting holes, with the limiting block slidably connected to the limiting holes.

[0011] Preferably, the slide rod passes through one end of the protective housing and is fixedly connected to the cover plate, and a sealing gasket is fixedly connected to the lower end of the cover plate.

[0012] Preferably, the second rotating rod passes through one end of the sampling cylinder and the protective shell and is fixedly connected to the lower end of the turntable.

[0013] Preferably, the upper end of the sampling tube is fixedly connected to a connecting seat, the lower end of the traction rope is connected to the connecting seat, and the lower end of the sampling tube is fixedly connected to four drain outlets.

[0014] A method for monitoring water resources for irrigation, using the monitoring device described above, includes the following steps:

[0015] S1. Fix the monitoring frame to the bank of the irrigation water area to be monitored, and then use the slider to drive the limit block to compress the spring. Place the filter frame into the inner wall of the inlet, release the slider to make the limit block snap into the limit hole to complete the fixation, and make the cover plate closed after installation.

[0016] S2. During sampling, the traction rope is released through the winding assembly, which drives the sampling cylinder to descend to the monitoring depth. The motor is then started to drive the rotating rod one and the half-tooth gear to rotate. The half-tooth gear meshes with the driven gear, which drives the rotating rod two and the turntable to rotate intermittently. The rotation of the turntable causes the first protrusion to push the slide rod to slide along the guide groove, which drives the cover plate to open the corresponding water inlet. After the water sample is filtered by the baffle, it flows into the sampling bottle through the water inlet. Then the second protrusion pushes the slide rod to reset and close the cover plate. The water samples from the four sampling bottles at different depths are collected in sequence. During the collection process, the depth of the sampling assembly is adjusted through the winding assembly to achieve layered sampling.

[0017] S3. After sampling is completed, the traction rope is retracted through the winding assembly, the sliding slider is removed from the filter frame to facilitate cleaning of the screen, and the drain outlet is opened to take out the water samples from the four sampling bottles.

[0018] Compared with the prior art, the present invention provides a water resource monitoring device and method for irrigation, which has the following beneficial effects:

[0019] Multiple water samples can be collected using four sampling bottles, eliminating the need for repeated lowering of the sampling components. Furthermore, the winding assembly controls the release and retraction of the traction rope, allowing adjustment of the sampling component's immersion depth and enabling the collection of water samples at different depths, significantly shortening the monitoring cycle. The intermittent rotation of the turntable is achieved through the meshing of a motor-driven half-gear and driven gear. Combined with protrusion one, protrusion two, guide groove, and slide rod assembly, the opening and closing of the cover plate can be controlled.

[0020] The screen can intercept impurities such as weeds and sand in the water, preventing them from entering the sampling bottle and contaminating the water sample. This ensures the purity of the water sample from the source and prevents impurities from interfering with subsequent test results. Attached Figure Description

[0030] Please see Figure 1-7 The present invention provides a technical solution for a water resource monitoring device for irrigation: including: a monitoring frame 1, a winding assembly 2 fixedly connected to the upper end of one side of the monitoring frame 1, and the winding assembly 2 is existing technology, used to wind or release the traction rope 3, the outer side wall of the winding assembly 2 is wound with the traction rope 3, and the lower end of the traction rope 3 is provided with a sampling assembly 4.

[0031] The sampling assembly 4 includes a sampling cylinder 401, with four sampling bottles 402 fixedly connected to the inner wall of the sampling cylinder 401. The four sampling bottles 402 are arranged in a circular array. Four water inlets 403 are fixedly connected to the upper end of the sampling cylinder 401. A filter assembly 5 is provided on the inner wall of each water inlet 403, and the four water inlets 403 are respectively connected to the four sampling cylinders 401. A protective shell 404 is fixedly connected to the upper end of the sampling cylinder 401, and a turntable 40 is fixedly connected to the inner wall of the protective shell 404. 5. A connecting rod 406 is fixedly connected to the outer wall of the turntable 405. A ring 407 is fixedly connected to one end of the connecting rod 406 and located on the outer wall of the turntable 405. A protrusion 408 and a protrusion 409 are fixedly connected to the outer wall of the turntable 405 and the inner wall of the ring 407, respectively. Four guide grooves 410 are fixedly connected to the inner wall of the protective shell 404. A sliding rod 411 is slidably connected to the inner wall of each of the four guide grooves 410. A stop block 412 is fixedly connected to the upper end of each of the four sliding rods 411. Through the four sampling bottles 402 in the sampling assembly 4, multiple sets of water samples can be collected simultaneously without multiple sampling, improving monitoring efficiency. It also enables comparative analysis of water samples at different depths, improving monitoring accuracy.

[0032] The upper end of the sampling cylinder 401 and both sides of the inlet 403 are fixedly connected to slide rails 4011, and a cover plate 4012 is slidably connected between the two slide rails 4011. The slide rails 4011 improve the stability of the cover plate 4012 when sliding, so that the cover plate 4012 covers the top of the inlet 403.

[0033] The sampling assembly 4 also includes a first rotating rod 41 and a second rotating rod 42 rotatably connected to the inner wall of the sampling cylinder 401. A half-tooth gear 43 is fixedly connected to the outer wall of the first rotating rod 41, and a driven gear 44 is fixedly connected to the outer wall of the second rotating rod 42. The driven gear 44 meshes with the half-tooth gear 43.

[0034] The filter assembly 5 includes a filter frame 501, a baffle 502 fixedly connected to the inner wall of the filter frame 501, grooves 503 on both sides of the filter frame 501, a limit block 504 slidably connected to the inner wall of the groove 503, a spring 505 fixedly connected to one side of the limit block 504, and the end of the spring 505 away from the limit block 504 connected to the inner wall of the groove 503. Two sliding grooves 506 are opened at the upper end of the filter frame 501, and the two sliding grooves 506 are respectively connected to the two grooves 503. A slider 507 is slidably connected to the inner wall of the sliding groove 506, and one end of the slider 507 is fixedly connected to the limit block 504. The baffle 502 can intercept weeds, sand and gravel and other impurities in the water, preventing impurities from entering the sampling bottle 402 and affecting the water sample test results; the limiting block 504, spring 505 and tank body 503 form a snap-fit ​​structure, which can install the filter frame 501 at the water inlet 403, or facilitate the disassembly of the filter frame 501.

[0035] The filter frame 501 is fitted to the inner wall of the inlet 403. Two limiting holes 4031 are provided on the inner wall of the inlet 403, and a limiting block 504 is slidably connected to the limiting holes 4031. This slidable connection between the limiting block 504 and the limiting holes 4031 secures the filter frame 501, preventing displacement of the filter frame 501 due to water flow impact during sampling.

[0036] A sliding rod 411 passes through one end of the protective housing 404 and is fixedly connected to the cover plate 4012. A sealing gasket is fixedly connected to the lower end of the cover plate 4012. The sliding rod 411 slides, causing the cover plate 4012 to slide, thereby realizing the closing and opening of the water inlet 403; the sealing gasket improves the sealing performance of the cover plate 4012.

[0037] Rotating rod 42 passes through the sampling cylinder 401 and the protective housing 404, and is fixedly connected to the lower end of the turntable 405. The rotation of the half-tooth gear 43 drives the driven gear 44 to rotate, which in turn drives the rotating rod 42 to rotate, thereby causing the turntable 405 to rotate.

[0038] A connecting seat 6 is fixedly connected to the upper end of the sampling cylinder 401, and the lower end of the traction rope 3 is connected to the connecting seat 6. Four drain outlets 7 are fixedly connected to the lower end of the sampling cylinder 401, and the four drain outlets 7 are respectively connected to four sampling bottles 402. A threaded cap is threadedly connected to the outer wall of the drain outlet 7 to facilitate the removal of water samples by the staff. The connecting seat 6 facilitates the connection between the traction rope 3 and the sampling cylinder 401.

[0039] A method for monitoring water resources for irrigation includes the following steps:

[0040] S1. Fix the monitoring frame 1 to the bank of the irrigation water area to be monitored, and then use the slider 507 to drive the limit block 504 to compress the spring 505. Place the filter frame 501 into the inner wall of the inlet 403, release the slider 507 so that the limit block 504 can be inserted into the limit hole 4031 to complete the fixation. After the installation is completed, make the cover plate 4012 in the closed state.

[0041] S2. During sampling, the traction rope 3 is released through the winding assembly 2, which drives the sampling cylinder 401 to descend to the monitoring depth. The motor 46 is started to drive the rotating rod 41 and the half-tooth gear 43 to rotate. The half-tooth gear 43 meshes with the driven gear 44, which drives the rotating rod 42 and the turntable 405 to rotate intermittently. The rotation of the turntable 405 causes the protrusion 408 to push the slide rod 411 to slide along the guide groove 410, which drives the cover plate 4012 to open the corresponding water inlet 403. After the water sample is filtered by the baffle 502, it flows into the sampling bottle 402 through the water inlet 403. Then the protrusion 409 pushes the slide rod 411 to reset and close the cover plate 4012. The water samples from different depths of the four sampling bottles 402 are collected in sequence. During the collection process, the depth of the sampling assembly 4 is adjusted by the winding assembly 2 to achieve layered sampling.

[0042] S3. After sampling is completed, the traction rope 3 is retrieved by the winding assembly 2, and the filter frame 501 is disassembled by sliding the slider 507 to facilitate cleaning of the baffle 502. The drain outlet 7 is then opened to take out the water samples from the four sampling bottles 402.

[0043] In practical use, this invention serves as a water resource monitoring device and method for irrigation. The monitoring frame 1 is fixed to the bank of the irrigation area to be monitored. The traction rope 3 is released via the winding assembly 2, causing the sampling cylinder 401 to reach a preset monitoring depth in the water. The motor 46 is then activated, driving the rotating rod 41 and the half-tooth gear 43 to rotate. The half-tooth gear 43 meshes with the driven gear 44, intermittently causing the rotating rod 42 to rotate. The rotating rod 42 drives the turntable 405 to rotate, which in turn pushes the corresponding sliding rod 411 along the guide groove 410 via the protrusion 408. The sliding rod 411 pushes the cover plate 40... 12 slides along the slide rail 4011, thereby opening the corresponding water inlet 403. At this time, the water sample is filtered by the baffle 502 and flows into the corresponding sampling bottle 402 through the water inlet 403. When the turntable 405 continues to rotate, the second protrusion 409 pushes the slide rod 411 to reset, causing the cover plate 4012 to close the water inlet 403 again. Through the intermittent rotation of the turntable 405, the water samples of the four sampling bottles 402 are collected in sequence. During the collection process, the length of the traction rope 3 can be adjusted by the winding component 2 to change the water depth of the sampling component 4, so as to realize the stratified collection of water samples at different depths and improve the monitoring accuracy.
