Description

A buoy frame for monitoring water quality in lotus root ponds Technical Field

[0001] This utility model relates to the field of lotus root pond water quality monitoring technology, and specifically discloses a lotus root pond water quality monitoring buoy frame. Background Technology

[0002] Lotus root ponds are artificial water bodies used for large-scale lotus root cultivation. Their water quality directly affects the growth, development, yield, and quality of the lotus roots. Lotus root growth depends on stable dissolved oxygen levels, pH levels, and nutrient concentrations in the water. Excessive fertilization, climate change, or eutrophication can easily lead to water quality deterioration, causing root diseases or growth disorders. Therefore, during lotus root cultivation, it is necessary to regularly monitor the water quality of the ponds, keeping abreast of key parameters such as dissolved oxygen, ammonia nitrogen, and turbidity to allow for timely adjustments to cultivation management measures (such as fertilization, aeration, and water exchange). Traditional water quality testing methods rely on manual, fixed-point sampling, which is inefficient and lacks data continuity. In contrast, buoy-mounted monitoring systems, equipped with water quality sensors, enable long-term online monitoring, making them an important piece of equipment in modern smart agriculture.

[0003] However, existing lotus pond water quality monitoring buoy frames have significant shortcomings: First, the installation position of the water quality detection sensors is usually fixed, making it difficult to detect water layers at different depths according to actual needs, resulting in insufficient flexibility in the use of the device; second, the buoy frames are mostly fixed to the bottom of the pond with weights and pulled by ropes to prevent them from drifting on the water surface, but the rope length is fixed and does not have an adjustment function, which cannot adapt to lotus ponds of different depths (such as the difference in water depth from 0.5 meters in shallow ponds to 2 meters in deep ponds), resulting in insufficient adaptability of the device to lotus ponds of different depths.

[0004] Therefore, a buoy for monitoring water quality in lotus root ponds is needed to solve the above problems. Summary of the Invention

[0005] This utility model proposes a buoy frame for monitoring water quality in lotus root ponds, which enables the height adjustment of the water quality detection sensor and allows for flexible detection at different water depths, significantly improving the flexibility of the device. At the same time, the length of the nylon rope in the water can be adjusted as needed to effectively adapt to lotus root ponds of different water depths.

[0006] This utility model is implemented as follows: a buoy frame for monitoring water quality in lotus root ponds includes a flat plate, a data transmitter, and a water quality detection sensor. Floats are installed at the four corners of the lower end face of the flat plate.

[0007] Two mounting brackets are fixedly connected to the upper end of the plate. Two rope holes are opened through the upper end surface of the plate. A winding shaft is rotatably connected inside the two mounting brackets. Nylon ropes that pass through the two rope holes are fixedly connected to the outer walls of the two winding shafts. A counterweight lead block is fixedly connected to the lower end of the two nylon ropes. A self-locking drive mechanism is provided on the opposite side of the two winding shafts.

[0008] A guide cylinder is fixedly connected to the upper end of the plate. An adjusting cylinder is inserted inside the guide cylinder. The water quality detection sensor is installed on the lower side inside the adjusting cylinder. A horizontal plate is fixedly connected to the upper end of the adjusting cylinder. The data transmitter is installed on the upper end of the horizontal plate. Multiple evenly distributed annular limiting grooves are opened on the outer wall of the adjusting cylinder. A locking mechanism is provided on the upper side of the plate.

[0009] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, the self-locking drive mechanism includes a drive frame fixedly connected to the outer wall of the mounting frame, a worm gear rotatably connected inside the drive frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the winding shaft, and a handwheel extending to the outside of the drive frame fixedly connected to the upper end of the worm gear.

[0010] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, the locking mechanism includes two vertical plates fixedly connected to the upper end of the flat plate. The outer walls of the two vertical plates are threaded with screws. The opposite ends of the two screws are rotatably connected to connecting plates. The opposite sides of the two connecting plates are fixedly connected to limiting blocks that fit against the inner wall of one of the annular limiting grooves. The opposite ends of the two screws are fixedly connected to hexagonal torsion blocks.

[0011] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, two solar panels are installed at the upper end of the horizontal plate.

[0012] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, the adjusting cylinder and the guide cylinder are fitted with a clearance.

[0013] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, the lower end of the regulating cylinder is fixedly connected to a protective net cover located on the outer wall of the water quality detection sensor.

[0014] As a preferred embodiment of the lotus root pond water quality monitoring buoy frame of this utility model, each of the two connecting plates has two sliding rods fixedly connected to the opposite side of the vertical plate and slidably connected to the vertical plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. By rotating the winding shaft to retract and extend the nylon rope, its submersion length can be adjusted, and its position can be fixed by utilizing its self-locking property. Thus, the submersion length of the nylon rope can be adjusted as needed, effectively adapting to lotus ponds of different water depths.

[0017] 2.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please refer to Figures 1-5. A buoy frame for monitoring water quality in a lotus pond includes a flat plate 1, a data transmitter 15, and a water quality sensor 16. Floats 2 are installed at the four corners of the lower end face of the flat plate 1.

[0027] Two mounting brackets 3 are fixedly connected to the upper end of the plate 1. Two rope holes 5 are opened through the upper end surface of the plate 1. A winding shaft 4 is rotatably connected inside the two mounting brackets 3. Nylon ropes 6 that pass through the two rope holes 5 are fixedly connected to the outer walls of the two winding shafts 4. A counterweight 7 is fixedly connected to the lower end of the two nylon ropes 6. A self-locking drive mechanism is provided on the opposite side of the two winding shafts 4.

[0028] A guide cylinder 11 is fixedly connected to the upper end of the plate 1. An adjusting cylinder 12 is inserted inside the guide cylinder 11. A water quality detection sensor 16 is installed on the lower side inside the adjusting cylinder 12. A horizontal plate 14 is fixedly connected to the upper end of the adjusting cylinder 12. A data transmitter 15 is installed on the upper end of the horizontal plate 14. Multiple evenly distributed annular limiting grooves 13 are opened on the outer wall of the adjusting cylinder 12. A locking mechanism is provided on the upper side of the plate 1.

[0029] In this embodiment: when it is necessary to adjust the length of the nylon rope 6 in the water, the self-locking drive mechanism drives the winding shaft 4 to rotate. The forward and reverse rotation of the winding shaft 4 can retract and extend the nylon rope 6, thereby adjusting the length of the nylon rope 6. When the device floats on the water surface, it can ensure that the counterweight 7 can contact the bottom of the lotus pond and that the nylon rope 6 is in a vertical state. The self-locking characteristic of the self-locking drive mechanism prevents the winding shaft 4 from rotating on its own, ensuring that the length of the nylon rope 6 is fixed. In this way, the length of the nylon rope 6 in the water can be adjusted as needed, effectively adapting to lotus ponds of different water depths.

[0030] When adjusting the water depth of the water quality sensor 16, the operator pulls the horizontal plate 14 up or down according to the monitoring requirements, causing the adjusting cylinder 12 to slide inside the guide cylinder 11, so that the water quality sensor 16 is in the required position according to the water depth being monitored. The position of the adjusting cylinder 12 is locked by the locking mechanism to ensure that the position of the water quality sensor 16 is stable during the monitoring process, thereby realizing the height adjustment of the water quality sensor 16. It can flexibly detect water layers of different depths, significantly improving the flexibility of the device.

[0031] During use, the floats 2 installed at the four corners of the lower end face of the plate 1 are made of hollow high-density polyethylene. The buoyancy makes the plate 1 float stably on the surface of the lotus pond, forming a water support structure. The water quality detection sensor 16 collects parameters such as dissolved oxygen, pH value, and ammonia nitrogen in real time. The water quality detection sensor 16 transmits the signal to the data transmitter 15. The data transmitter 15 converts the sensor signal into a digital signal and sends it to the remote monitoring platform through the 4G network. The management personnel can obtain water quality data in real time and realize real-time monitoring of the lotus pond water quality.

[0032] During this process, the two counterweight lead blocks 7 are in contact with the bottom of the pool, and the device can be prevented from drifting by the pull of the two nylon ropes 6;

[0033] It should be noted that the data transmitter 15 mainly consists of a main control unit, a communication module, a power management unit, and a wireless antenna. The main control unit contains a microprocessor chip for receiving and processing signals from the water quality sensor 16. The communication module supports wireless communication standards such as 4G, NB-IoT, or LoRa. The antenna is used for signal transmission and reception. The power management unit integrates buck and boost circuits, adapts to solar power supply, and provides a stable voltage for the device. It receives digital signals output by the water quality sensor 16 through a wired interface. After being packaged and encoded by the main control unit, the signals are sent to the remote monitoring platform via a wireless communication network by the communication module, realizing remote data transmission and interaction. The water quality sensor 16 consists of a detection probe, a signal amplification circuit, and an analog-to-digital conversion module. The detection probe directly contacts the water body to collect physical or chemical parameters. The signal amplification circuit amplifies the weak electrical signals output by the probe. The analog-to-digital conversion module converts analog signals into digital signals. Both the data transmitter 15 and the water quality sensor 16 adopt mature modular products in this field, and their internal circuit structure, component selection, and signal processing logic are all existing technologies.

[0034] As a technical optimization of this utility model, the self-locking drive mechanism includes a drive frame 8 fixedly connected to the outer wall of the mounting frame 3, a worm 9 rotatably connected inside the drive frame 8, a worm wheel 10 meshing with the outer wall of the worm 9, a transmission shaft fixedly connected between the worm wheel 10 and the winding shaft 4, and a handwheel extending to the outside of the drive frame 8 fixedly connected to the upper end of the worm 9.

[0035] In this embodiment: the operator rotates the handwheel on the outside of the drive frame 8, which drives the worm 9 to rotate. Through the meshing transmission between the worm 9 and the worm wheel 10, the drive shaft drives the winding shaft 4 to rotate. Due to the self-locking characteristics of the worm 9 and the worm wheel 10, the winding shaft 4 cannot rotate on its own, ensuring that the length of the nylon rope 6 is fixed.

[0036] As a technical optimization of this utility model, the locking mechanism includes two vertical plates 18 fixedly connected to the upper end of the flat plate 1. The outer walls of the two vertical plates 18 are threadedly connected with screws 19. The opposite ends of the two screws 19 are rotatably connected with connecting plates 20. The opposite sides of the two connecting plates 20 are fixedly connected with limiting blocks 21 that fit against the inner wall of one of the annular limiting grooves 13. The opposite ends of the two screws 19 are fixedly connected with hexagonal torsion blocks 22.

[0037] In this embodiment: the two limiting blocks 21 are aligned with a corresponding annular limiting groove 13. Then, the hexagonal torsion block 22 can be rotated by a wrench to drive the screw 19 to rotate, so that the limiting block 21 on the connecting plate 20 is engaged in the inner wall of the annular limiting groove 13 until the limiting block 21 is tightly abutted against the inside of the annular limiting groove 13, thereby locking the position of the adjusting cylinder 12.

[0038] As a technical optimization of this utility model, two solar panels 23 are installed at the upper end of the horizontal plate 14.

[0039] In this embodiment, two solar panels 23 are installed at an angle on the upper side of the horizontal plate 14. They convert light energy into electrical energy through the photovoltaic effect, directly powering the data transmitter 15 and the water quality sensor 16. Excess electrical energy is stored in the built-in battery.

[0040] As a technical optimization of this utility model, the adjusting cylinder 12 and the guide cylinder 11 are in clearance fit.

[0041] In this embodiment, since the adjusting cylinder 12 and the guide cylinder 11 are in clearance fit, the guide cylinder 11 is prevented from jamming the adjusting cylinder 12.

[0042] As a technical optimization of this utility model, the lower end of the regulating cylinder 12 is fixedly connected to a protective mesh cover 17 located on the outer wall of the water quality detection sensor 16.

[0043] In this embodiment, a protective mesh cover 17 is provided to prevent external impacts from damaging the water quality detection sensor 16.

[0044] As a technical optimization of this utility model, two sliding rods are fixedly connected to the opposite sides of the two connecting plates 20, and are slidably connected to the vertical plates 18.

[0045] In this embodiment: when the screw 19 rotates, the slide bar restricts the movement trajectory of the connecting plate 20, so that it can only move in the horizontal direction, avoiding the tilting of the connecting plate 20 due to the rotation of the screw 19, and ensuring that the limiting block 21 is accurately engaged in the annular limiting groove 13.

[0046] The working principle and usage process of this utility model are as follows: When adjusting the water entry length of the nylon rope 6, the operator rotates the handwheel on the outside of the drive frame 8, which drives the worm 9 to rotate. Through the meshing transmission between the worm 9 and the worm wheel 10, the drive shaft drives the winding shaft 4 to rotate. Then, through the forward and reverse rotation of the winding shaft 4, the nylon rope 6 can be wound up and unwound, thereby adjusting the length of the nylon rope 6. When the device floats on the water surface, it can ensure that the counterweight lead block 7 can contact the bottom of the lotus pond, and the nylon rope 6 is in a vertical state. Due to the self-locking characteristics of the worm 9 and the worm wheel 10, the winding shaft 4 cannot rotate on its own, ensuring that the length of the nylon rope 6 is fixed. In this way, the water entry length of the nylon rope 6 can be adjusted as needed, effectively adapting to lotus ponds of different water depths.

[0047] When adjusting the water depth of the water quality sensor 16, the operator pulls the horizontal plate 14 up or down according to the monitoring requirements, causing the adjusting cylinder 12 to slide inside the guide cylinder 11. This positions the water quality sensor 16 according to the required water depth and aligns the two limiting blocks 21 with the corresponding annular limiting groove 13. Then, the hexagonal torsion block 22 can be rotated with a wrench to rotate the screw 19, causing the limiting block 21 on the connecting plate 20 to engage with the inner wall of the annular limiting groove 13 until the limiting block 21 is tightly abutted against the inside of the annular limiting groove 13. This locks the position of the adjusting cylinder 12, ensuring the stability of the water quality sensor 16 during monitoring. This allows for height adjustment of the water quality sensor 16, enabling flexible detection of different water depths and significantly improving the flexibility of the device.

[0048] In use, the floats 2 installed at the four corners of the lower end of the plate 1 are made of hollow high-density polyethylene. The buoyancy makes the plate 1 float stably on the surface of the lotus pond, forming a water support structure. The two solar panels 23 on the upper end of the horizontal plate 14 are installed at an angle. Through the photovoltaic effect, light energy is converted into electrical energy to power the data transmitter 15 and the water quality sensor 16. The water quality sensor 16 collects parameters such as dissolved oxygen, pH value, and ammonia nitrogen in real time. The water quality sensor 16 transmits the signal to the data transmitter 15. The data transmitter 15 converts the sensor signal into a digital signal and sends it to the remote monitoring platform through the 4G network. The managers can obtain water quality data in real time and realize real-time monitoring of the lotus pond water quality.

[0049] During this process, the two counterweights 7 are in contact with the bottom of the pool, and the device is prevented from drifting by the pull of the two nylon ropes 6.
