TECHNICAL FIELD
[0001] The present application relates to the technical field of water environment detection, in particular to a dead water area water environment detection device and an operation method thereof. BACKGROUND
[0002] Water environment monitoring is a key link for ecological environment protection, rational utilization of water resources and public health protection, and the water quality monitoring of dead water area has special significance. Due to the lack of effective water exchange, the water body in this area is prone to form a stable vertical stratification structure, which is characterized by: the surface water body is affected by light and air exchange, has high dissolved oxygen content, relatively stable temperature, and may be rich in plankton and surface pollutants; the middle layer water body is a transition area, and various water quality parameters change with depth; the bottom layer water body has low dissolved oxygen content due to insufficient light and microbial decomposition, and is easy to accumulate pollutants such as nitrogen, phosphorus, heavy metals and volatile organic compounds released by sediments. Currently, the industry generally uses a suction type water sampling detection scheme for water environment detection in dead water area. The core operation process is: a guide pipe with a water inlet is lowered to the target water layer, a vacuum pump, a syringe or a negative pressure device connected to the other end of the guide pipe generates negative pressure, the water in the target water layer is sucked into the guide pipe by the negative pressure, and then transported to a detection instrument or a sampling container to complete water quality parameter detection or sample preservation. The suction type water sampling relies on the water flow power generated by negative pressure to realize water collection. When negative pressure acts on the water inlet of the guide pipe, a local high flow field will be formed around the water inlet. This water flow field not only drives the water in the target water layer into the guide pipe, but also strongly disturbs the water bodies in the surrounding different layers, causing the upper, middle and bottom water bodies to mix, breaking the original stable stratification interface, and making the collected water sample become a mixture of water bodies in different layers, which cannot truly reflect the original water quality state of the target water layer. Secondly, water flow disturbance causes water quality parameter distortion. The physical, chemical and biological characteristics of each stratified water body in the dead water area are in a relatively stable balance state, and the high flow water flow generated by the suction process will break this balance: on the one hand, water flow disturbance will increase the contact area between water and air, causing the dissolved oxygen content of the bottom water body originally in anaerobic state to increase, thereby changing the oxidation-reduction potential of the water body, causing a series of chemical reactions such as heavy metal form transformation and organic matter degradation path change, and making the detected parameters such as dissolved oxygen, chemical oxygen demand and heavy metal activity have significant deviation from the actual value; on the other hand, water flow disturbance will cause the redistribution of suspended particles in the water body, and the sediment particles originally settled in the bottom layer will be lifted into the sampling water body, causing the turbidity and suspended solids concentration detection value to be high, and also interfering with the detection results of total phosphorus and total nitrogen which exist in the form of particles. In summary, the traditional suction type water intake detection scheme cannot avoid the damage to the water layering in the dead water area during the water intake process, which leads to the detection data unable to accurately reflect the real water quality condition of each water layer, and seriously restricts the scientificity and reliability of the water environment monitoring in the dead water area. Therefore, a dead water area water environment detection device capable of effectively protecting the water layering structure during the water intake process and ensuring the detection accuracy is needed.

[0010] Preferably, the arc-shaped rotating plate is made of transparent material, a detection opening is fixedly installed at the top end of the arc-shaped rotating plate, and a sealing plug is detachably installed in the detection opening.
[0011] An operating method of the water environment detection device for dead water area, comprising the water environment detection device for dead water area, and comprising the following operating steps: S1: installing the suspension bracket at a designated position and making the mounting rod located directly above the water taking position; S2: moving the suspension rod downward until the mounting rod reaches a designated depth; S3: opening one valve, the air feeding assembly feeds air into the arc-shaped cylinder rod, the increased pressure in the arc-shaped cylinder rod makes the movable plug slide in the arc-shaped cylinder rod, the arc-shaped inner rod pushes the arc-shaped rotating plate to move to the water taking space until the arc-shaped rotating plate seals the water taking space; S4: after the movable plug moves to one side of the air feeding pipe, the air feeding pipe is in communication with the high-pressure cavity in the arc-shaped cylinder rod, the air in the high-pressure cavity enters the soft cavity bag through the air feeding pipe, the soft cavity bag is tightly attached to the inner surface of the arc-shaped rotating plate after expansion, and the sealing effect is ensured; S5: subsequently, the suspension rod is lifted to detect the water in the water taking space.
[0012] Compared with the prior art, the water environment detection device for dead water area and the operating method thereof have the following beneficial effects: 1、The device forms independent water taking space through the fixed partition with ladder distribution, and realizes closed water taking by cooperating with the rotatable arc-shaped rotating plate. When the installation rod is lowered to the specified depth, the water sample naturally fills the water taking space. At this time, air is sent into the arc-shaped cylinder rod through the air sending assembly, which pushes the movable plug and the arc-shaped inner rod to move, so that the arc-shaped rotating plate slowly covers and closes the water taking space. The whole water taking process has no water flow disturbance, and the water body always keeps static state, completely avoiding the problem of breaking the stable stratification interface, ensuring that the water sample closed in the water taking space completely corresponds to the target water layer, and the detection data can truly reflect the key water quality parameters such as dissolved oxygen, pollutant concentration and suspended particulate matter in the water layer, providing accurate data support for water environment evaluation and treatment in dead water area; 2、Based on the design of multiple independent water taking spaces and matching drive structure, each water taking space corresponds to an independent arc-shaped rotating plate, arc-shaped cylinder rod and air sending control valve. The water taking operation of each water taking space does not interfere with each other. During detection, the valve of different air outlet ends can be controlled to complete the water sample collection of multiple water layers, greatly reducing the water taking steps and operation time. Especially in the multi-point and multi-layer monitoring scene of large-area dead water area, the overall detection efficiency can be significantly improved, the monitoring cycle can be shortened, and the needs of water environment emergency monitoring or normal high-frequency monitoring can be met; 3、The screw rod lifting structure driven by motor is adopted. The motor drives the gear to rotate, the gear engages with the gear ring to drive the screw rod to lift, and the cooperation of the limiting slide block and the limiting slide groove ensures that the screw rod lifting process is stable and has no rotation deviation. Compared with the traditional manual lifting method, this structure does not need manual labor to adjust, the lowering depth of the installation rod can be accurately controlled by controlling the start and stop of the motor, the error is smaller, and the water layer can be accurately positioned to the preset detection water layer, which further guarantees the pertinence and accuracy of water sample collection. In addition, the automatic lifting design reduces the labor intensity of the operator, especially suitable for deep water area or long-time continuous monitoring scene, which improves the operation convenience and practicality of the equipment; 4、Traditional detection needs to take out the water sample from the water taking equipment and transfer it to the detection instrument. During the transfer process, the water sample is easy to change the water quality parameters due to air contact (such as the increase of dissolved oxygen in the bottom anaerobic water sample), container pollution or water flow disturbance, which affects the accuracy of detection results. The arc-shaped rotating plate of the device is made of transparent material, and a detection port with a sealing plug is arranged on it. During detection, the water sample does not need to be taken out, and only the sealing plug needs to be opened, and the detection device is directly inserted into the water taking space through the detection port for in-situ detection. This design completely avoids the secondary disturbance in the water sample transfer process, ensures that the detection process is consistent with the original state of the water sample, and further guarantees the reliability of the detection results, especially suitable for the detection of parameters such as dissolved oxygen, pH value and oxidation-reduction potential which are easily affected by the environment; 5. After the arc-shaped rotating plate seals the water intake space, high-pressure air inside the arc-shaped cylinder enters the soft chamber bag through the air supply pipe and air passage. This causes the soft chamber bag to expand and tightly adhere to the inner surface of the arc-shaped rotating plate, forming a dual guarantee of "physical sealing + elastic sealing." This structure effectively solves the problem of decreased sealing effect of the arc-shaped rotating plate after long-term use, completely preventing external water from entering the water intake space or water sample leakage within the water intake space. It avoids cross-contamination of water samples from different water layers, ensuring that the water sample in the water intake space always remains in its original state, providing stable and pure water samples for subsequent testing, and further improving the reliability of the test data.
