Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring, and in particular to a water quality monitoring device for grass-covered water bodies. Background Technology

[0002] As an important component of aquatic ecosystems, grass-covered water bodies have a crucial impact on aquatic biodiversity, ecological balance, and the quality of the surrounding environment. Accurate and timely monitoring of water quality parameters in grass-covered water bodies is an important means of preventing water pollution and assessing the effectiveness of ecological restoration.

[0003] Currently, water quality monitoring in grassy water bodies primarily employs a combination of manual sampling and laboratory analysis, or utilizes fixed-point online monitoring equipment. Manual sampling suffers from high labor intensity, low sampling frequency, and poor data timeliness, making it difficult to capture dynamic changes in water quality. Meanwhile, fixed-point online monitoring equipment is typically installed in fixed locations, limiting its monitoring range and hindering effective monitoring of different areas of the water body, especially those far from the shore or with complex aquatic plant distribution. Furthermore, the abundant aquatic plants in grassy water bodies can easily entangle and clog monitoring equipment, affecting its normal operation and the accuracy of monitoring data. Therefore, there is an urgent need for water quality monitoring equipment that can flexibly adjust its monitoring location and adapt to the complex environment of grassy water bodies.

Detailed Implementation

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Reference Figures 1-4 This embodiment provides a water quality monitoring device for grass-type water bodies, including a support frame 1, which is set on the bank of the water source. A rotating mechanism is set on the support frame 1, and a support column 11 is vertically set on the rotating mechanism.

[0037] Extension mechanism 2, mounted on support column 11, is used to adjust the distance for water sample collection;

[0038] Sampling and monitoring unit 3 is installed on extension unit 2 and is used to collect water samples;

[0039] Among them, sampling and monitoring agency 3 includes:

[0040] A winding and discharging machine 31 is mounted on the extension mechanism 2. A take-up reel 32 is rotatably mounted at the output end of the winding and discharging machine 31, and a lifting rope 33 is wound on the take-up reel 32.

[0041] A lifting block 34 is attached to the end of a lifting rope 33. A clamping mechanism is provided on the lifting block 34, and a sampling monitoring bottle 35 is provided in the clamping mechanism.

[0042] The guide wheel 36 is rotatably mounted on the extension mechanism 2 and is used to guide the hoisting rope 33.

[0043] In this embodiment, the rotating mechanism on the support frame 1 drives the support column 11 to rotate, enabling the device to face different areas of the water body. This overcomes the limitation of fixed-point monitoring devices that can only monitor in a fixed direction, allowing it to be aimed at areas far from the shore or with complex aquatic plant distribution. The extension mechanism 2 on the support column 11 extends and retracts to adjust the distance between the sampling monitoring device 3 and the shore, allowing the sampling point to penetrate into different locations within the water body, thus solving the problem of limited monitoring range of fixed-point online monitoring devices. The winding and discharging motor 31 on the extension mechanism 2 is activated, and its output... The output end drives the take-up reel 32 to rotate, thereby realizing the winding and unwinding operation of the hoisting rope 33 wound on the take-up reel 32; when water samples need to be collected, the reel motor 31 releases the rope, and the hoisting block 34 attached to the end of the rope 33 lowers the sampling and monitoring bottle 35 to the water body at the specified depth under the action of gravity; during this process, the guide wheel 36 set on the extension mechanism 2 guides the hoisting rope 33 to ensure the stability of the hoisting rope 33's movement trajectory, so that the sampling and monitoring bottle 35 accurately reaches the predetermined position; after reaching the predetermined depth, the clamping mechanism on the hoisting block 34 fixes the sampling and monitoring bottle 35. The sampling bottle 35 is used to stably collect water samples. After collection, the rope is wound up by the discharge motor 31, pulling the sampling bottle 35 back to the water surface for subsequent analysis. The rotating mechanism and the extension mechanism 2 work together to allow the equipment to flexibly change the sampling position according to actual needs. The rotating mechanism can change the monitoring direction, and the extension mechanism 2 can adjust the sampling distance, effectively overcoming the limitations of fixed-point online monitoring equipment. It can monitor the water quality of different areas of grassy water bodies. The equipment uses a combination of suspension rope 33, suspension block 34, and sampling bottle 35 for water sample collection, which is relatively flexible and less prone to being entangled or blocked by aquatic plants. Even in grassy water bodies with abundant aquatic plants, the sampling bottle 35 can avoid the plants and reach the designated location to collect water samples smoothly with the help of the rotating mechanism and the extension mechanism 2. This reduces the impact of aquatic plants on the operation of the equipment, improves the accuracy of monitoring data, and can capture the dynamic changes in water quality in a timely manner, thereby discovering water quality problems more promptly. It provides timely and accurate data support for preventing water pollution and assessing the effect of ecological restoration, solving the problems of high labor intensity and poor data timeliness of manual sampling.

[0044] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, the clamping mechanism includes:

[0045] Two hinge pieces 3a are oscillatingly mounted at the bottom of the lifting block 34;

[0046] Two clamping rods 3b are respectively oscillatingly mounted on two hinged plates 3a, and each clamping rod 3b is provided with an arc-shaped clamping plate 3d;

[0047] Submersible pad 3c is hinged to the bottom ends of the two clamping rods 3b.

[0048] In this embodiment, the sampling and monitoring bottle 35 is placed on the submerged pad 3c. Then, under the weight of the sampling and monitoring bottle 35 and the submerged pad 3c, the two clamping rods 3b are pulled downwards. The two clamping rods 3b, in conjunction with the two hinged pieces 3a, cause the two clamping rods 3b to swing inwards, thereby clamping the sampling and monitoring bottle 35 with the arc-shaped clamping plate 3d. The clamping action of the clamping rods 3b and the arc-shaped clamping plate 3d is controlled by the weight of the submerged pad 3c and the sampling and monitoring bottle 35, eliminating the need for an additional power device. In complex environments such as grassy water bodies, this reduces the risk of failure caused by complex mechanical structures or electrical components, improving the reliability and stability of the equipment. It can better adapt to situations such as entanglement of aquatic plants and changes in water flow that may occur in grassy water bodies. The design of the arc-shaped clamping plate 3d can better conform to the shape of the sampling and monitoring bottle 35, providing uniform pressure during clamping and avoiding damage to the sampling and monitoring bottle 35. This ensures the integrity of the sampling and monitoring bottle 35 during the sampling process, thereby guaranteeing that the collected water samples are not affected by external factors and improving the accuracy of the monitoring data.

[0049] Specifically, anti-slip protrusions are provided on the inner side wall of the 3D curved clamp;

[0050] In this embodiment, the grass-like aquatic environment is relatively complex, with water flow fluctuations and equipment shaking. The anti-slip protrusions can effectively increase the friction between the arc-shaped clamp 3d and the sampling and monitoring bottle 35, ensuring that the sampling and monitoring bottle can be firmly clamped even if it is disturbed by external factors during equipment operation, avoiding sampling failure or equipment damage due to slippage. The stable clamping state helps to ensure that the sampling and monitoring bottle maintains the correct position and posture during the water sample collection process, reducing the impact of bottle shaking or displacement on sampling, thereby improving the accuracy and representativeness of the collected water samples.

[0051] More specifically, the 3c submersible pad is made of solid stainless steel.

[0052] In this embodiment, the solid stainless steel submersible pad 3c has a density greater than water, generating sufficient gravity to overcome the buoyancy of water and potential water flow resistance, ensuring that the sampling monitoring bottle 35 sinks smoothly to the designated depth of water for sampling. This avoids the problem of not being able to collect water samples at a specific depth due to the sampling monitoring bottle 35 floating, thus ensuring the accuracy and effectiveness of sampling. The weight of the submersible pad 3c causes the clamping rod 3b and the arc-shaped clamping plate 3d to generate a stable clamping force on the sampling monitoring bottle 35 during the sinking process. In the aquatic environment, there may be water flow fluctuations, and this stable clamping can prevent the sampling monitoring bottle 35 from shaking or falling off during the sampling process, ensuring the stability and reliability of the sampling process.

[0053] Furthermore, such as Figures 1 to 2 As shown, the extension mechanism 2 includes:

[0054] Transmission box 21 is fixedly connected to support column 11. An extension motor 22 is provided on transmission box 21. The power output end of extension motor 22 is connected to the power input end of transmission box 21.

[0055] A crossbar 23 is fixedly installed on a transmission box 21. A threaded sleeve 24 is rotatably installed inside the crossbar 23. The threaded sleeve 24 drives the transmission box 21 through an extension motor 22, and the transmission box 21 drives the rotation. The winding and discharging machine 31 is fixedly connected to the outer wall of the crossbar 23.

[0056] An extension screw 25 is slidably inserted into a crossbar 23. The extension screw 25 is threadedly engaged with a threaded sleeve 24. A guide wheel 36 is rotatably mounted on the extension screw 25.

[0057] In this embodiment, the extension motor 22 starts, and its power output end transmits power to the transmission box 21; the transmission box 21 then transmits power to the threaded sleeve 24 inside the crossbar 23, causing the threaded sleeve 24 to rotate; since the extension screw 25 is threadedly engaged with the threaded sleeve 24, when the threaded sleeve 24 rotates, according to the thread transmission principle, the extension screw 25 will extend or retract within the crossbar 23; as the extension screw 25 extends or retracts, the guide wheel 36 mounted on it also moves accordingly, and at the same time, the position of the winding and discharging machine 31 fixed on the outer wall of the crossbar 23 is relative to the crossbar 23. The distance between the sampling and monitoring mechanism 3 and the shoreline changes as the extension screw 25 moves, thereby moving the entire sampling and monitoring mechanism 3 and adjusting the distance for water sample collection to meet the needs of water sample collection at different locations. By extending or retracting the extension screw 25 in the extension mechanism 2, the distance between the sampling and monitoring mechanism 3 and the shoreline can be flexibly changed, allowing water sample collection in water areas that are closer to or farther from the shoreline. This effectively solves the problem of limited monitoring range of fixed-point online monitoring equipment and enables monitoring of water quality in different areas of grassy water bodies, thus expanding the monitoring range of the equipment.

[0058] Furthermore, such as Figure 4 As shown, the rotating mechanism includes:

[0059] The bearing housing 12 is fixedly mounted on the support frame 1;

[0060] Turntable 13 is rotatably mounted on bearing housing 12, and gear ring 14 is fitted on turntable 13;

[0061] A rotary motor 15 is fixedly mounted on a support frame 1. A gear 16 is provided at the output end of the rotary motor 15, and the gear 16 meshes with a gear ring 14.

[0062] In this embodiment, the rotary motor 15 is powered on and started, and the gear 16 at its output end begins to rotate. Since the gear 16 meshes with the gear ring 14, the rotation of the gear 16 will drive the gear ring 14 to rotate. The gear ring 14 is fitted on the turntable 13, so the rotation of the gear ring 14 will drive the turntable 13 to rotate on the bearing seat 12. The turntable 13 is connected to the support column 11, and the rotation of the turntable 13 will drive the support column 11 to rotate, thereby causing the extension mechanism 2 and the sampling and monitoring mechanism 3 installed on the support column 11 to rotate together, realizing the monitoring of water bodies in different directions. Through the rotation of the rotating mechanism, the sampling and monitoring mechanism 3 can be oriented in different directions, and the water quality of different areas of the grass-like water body can be monitored. This solves the problem of fixed monitoring direction of fixed-point online monitoring equipment, expands the monitoring range of the equipment, can capture water quality changes in different areas, and improves the comprehensiveness and accuracy of monitoring. The distribution of aquatic plants in grass-like water bodies is complex, and there may be water areas in different directions that need to be monitored. The rotating mechanism allows the equipment to flexibly adjust the monitoring direction, avoid the entanglement and blockage of aquatic plants, and ensure the normal operation of the equipment and the accuracy of the monitoring data.

[0063] Furthermore, a counterweight is provided on the support frame 1;

[0064] In this embodiment, the counterweight can effectively balance the center of gravity of the equipment under different working conditions. In environments such as grassy water bodies, there may be uneven ground. The counterweight can help the equipment better adapt to different working positions and postures, preventing the equipment from shaking or tipping over during rotation, extension, and other operations, ensuring stable operation and improving equipment safety. Stable equipment operation can reduce stress and wear on the equipment structure caused by shaking or tipping. The counterweight keeps the equipment balanced under different working conditions, allowing the equipment to reach a larger working range during rotation and extension operations, expanding the monitoring range of the equipment, and improving the working capacity of the equipment.

[0065] Furthermore, such as Figure 1 As shown, a diagonal brace 17 is provided on the support column 11, and the diagonal brace 17 is fixedly connected to the bottom end of the crossbar 23;

[0066] In this embodiment, the diagonal brace 17 connects the support column 11 and the crossbar 23, forming a stable triangular structure, which can effectively enhance the overall stability of the equipment. When the equipment is performing sample collection operations, the crossbar 23 can stably support the sampling and monitoring mechanism 3, preventing the crossbar 23 from tilting or deforming due to force, and ensuring that the sampling and monitoring mechanism 3 can accurately collect water samples.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
