Description

Technical Field

[0001] This utility model relates to the field of water environment monitoring technology, specifically to an auxiliary device for water environment monitoring. Background Technology

[0002] A smart water environment monitoring station is a device integrating sensor, communication, data processing, and analysis technologies. It is primarily used to monitor various environmental indicators of water bodies in real time, ensuring water quality meets safety standards and providing accurate water environment data. Inside the monitoring station is a corresponding sedimentation tank for pre-treating water samples. Sedimentation removes large suspended solids and silt, ensuring the water samples entering the sensors and other monitoring equipment are relatively clean. Existing sedimentation tanks are mostly rectangular boxes with flat bottoms. After sedimentation, wastewater is discharged from the bottom via a corresponding drain valve. Due to the horizontal structure of the bottom, drainage is incomplete, and accumulated sediment cannot be thoroughly removed. This leads to long-term sediment buildup, causing sludge accumulation in the tank, affecting the treatment capacity of the sedimentation tank, reducing the accuracy of water quality monitoring, and shortening the equipment's lifespan. Furthermore, poor drainage not only results in incomplete sediment removal but may also cause secondary water pollution, affecting subsequent water quality testing and treatment efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for water environment monitoring, comprising:

[0005] A sedimentation tank is a cavity with openings at both the top and bottom. Two partition plates are fixedly connected inside the sedimentation tank. An overflow port is provided at the top of the partition plates. A conical bottom plate is slidably connected inside the sedimentation tank. A drive unit for driving the conical bottom plate to rise and fall is provided at the top of the sedimentation tank.

[0006] The receiving cavity is fixed to the bottom of the sedimentation tank. The cross-sectional area of ​​the receiving cavity is larger than the bottom area of ​​the conical bottom plate. A drainage funnel is fixedly connected to the bottom of the receiving cavity.

[0008] Preferably, one end of the sedimentation tank is fixedly connected to an inlet pipe, and the other end of the sedimentation tank opposite to the inlet pipe is fixedly connected to an outlet pipe. The outlet pipe is connected to a sampling box, and a solenoid valve is installed on the outside of the outlet pipe.

[0009] Preferably, the drive unit includes a top cover fixed to the top of the sedimentation tank, an electric push rod fixedly connected to the top of the top cover, the output end of the electric push rod passing through the top cover and fixedly connected to the conical bottom plate, and two limiting rods fixedly connected to the top of the conical bottom plate, the limiting rods being slidably connected to the top cover.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: The sedimentation tank is divided into multiple water storage and sedimentation spaces by two partition plates. As water flows through these spaces sequentially, it undergoes multiple sedimentation processes, effectively removing impurities such as silt and sand, improving the sedimentation effect, and providing more reliable water samples for subsequent accurate water quality monitoring. The conical bottom plate and the partition plates form the sedimentation space. Its conical structure facilitates the accumulation of silt at the bottom. During cleaning, an electric push rod drives the conical bottom plate to rise and fall, cleaning the silt at the top of the conical bottom plate. When cleaning is required, the electric push rod drives the conical bottom plate downward into the receiving cavity. Under the impact of water stored between the partition plates, silt and water flow from the gaps on the inclined surface of the conical bottom plate into the drainage funnel and are discharged. The water is then sprayed onto the conical bottom plate through the spray pipe to rinse it, further enhancing the cleaning effect. After cleaning, the electric push rod drives the conical bottom plate back to its original position to seal the bottom of the sedimentation tank. This automates the silt cleaning process, simplifies operation, and improves cleaning efficiency. Attached Figure Description

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: an auxiliary device for water environment monitoring, comprising: a sedimentation tank 1, which is a cavity with openings at both the top and bottom; two partition plates 8 are fixedly connected inside the sedimentation tank 1 to divide the interior of the sedimentation tank 1 into multiple water storage and sedimentation spaces; an overflow port 9 is provided at the top of the partition plates 8; a conical bottom plate 7 is slidably connected inside the sedimentation tank 1; a sealing ring is fixedly connected to the outer side of the bottom of the conical bottom plate 7 to control the flow between the conical bottom plate 7 and the sedimentation tank. The inner wall of the sand tank 1 is sealed at the joint. The partition plate 8 and the conical bottom plate 7 form a sedimentation space. The top of the sand tank 1 is equipped with a drive unit to drive the conical bottom plate 7 to rise and fall. The receiving cavity 2 is fixed to the bottom of the sand tank 1. The cross-sectional area of ​​the receiving cavity 2 is larger than the bottom area of ​​the conical bottom plate 7. The bottom of the receiving cavity 2 is fixedly connected to a drainage funnel 3. The sampling box 11 is fixed to one side of the sand tank 1. The top of the sampling box 11 is equipped with a vent hole. The bottom of the sampling box 11 is equipped with a negative pressure bottle 14 for sample retention.

[0023] It should be noted that a controller is provided in this embodiment. The water pump injects water from one end of the sedimentation tank 1. After sedimentation in the space formed by the partition plate 8, the conical bottom plate 7 and the sedimentation tank 1, the water flows forward through the overflow port 9 and then enters the sampling box 11. When it is necessary to clean the mud and sand on the top of the conical bottom plate 7, the drive unit drives the conical bottom plate 7 to move downward, so that the conical bottom plate 7 enters the receiving cavity 2. Because the volume of the receiving cavity 2 is large, under the impact of the water stored between the partition plates 8, the mud and sand and water flow along the slope of the conical bottom plate 7 from the gap between the conical bottom plate 7 and the inner wall of the receiving cavity 2 into the drainage funnel 3. The drainage funnel 3 is connected to the outside through a water pipe to discharge the mud and sand. After the discharge is completed, the drive unit drives the conical bottom plate 7 to return to its original position, thereby sealing the bottom of the sedimentation tank 1.

[0024] In one embodiment, an inlet pipe 15 is fixedly connected to one end of the sedimentation tank 1, and an outlet pipe 16 is fixedly connected to the other end of the sedimentation tank 1 away from the inlet pipe 15. The outlet pipe 16 is connected to the sampling box 11, and a solenoid valve 17 is installed on the outside of the outlet pipe 16.

[0025] It should be noted that in this embodiment, the inlet pipe 15 is connected to the input end of the water pump and is used to send the water to be tested into the sedimentation tank 1 for preliminary sedimentation treatment. The settled water is then sent to the sampling box 11 through the outlet pipe 16. The sampling box 11 is equipped with a water level switch that is electrically connected to the solenoid valve 17. When the water in the sampling box 11 reaches the preset water level, the water level switch transmits the signal to the controller, and the controller controls the solenoid valve 17 to close.

[0027] It should be noted that, in this embodiment, when the conical bottom plate 7 is driven, the electric push rod 5 drives the conical bottom plate 7 to move downward, and the conical bottom plate 7 drives the limiting rod 6 to move downward along the top cover 4. In this way, the conical bottom plate 7 separates downward from the bottom of the sedimentation tank 1, so that the sediment and water at the top of the conical bottom plate 7 flow downward through the receiving cavity 2 into the drainage funnel 3 for discharge. Under the action of the timer, the electric push rod 5 drives the conical bottom plate 7 to move upward, sealing the bottom of the sedimentation tank 1, so that the top of the conical bottom plate 7 contacts and seals with the partition plate 8.

[0028] In one embodiment, a plurality of spray pipes 19 are fixed to the bottom of the top cover 4 for rinsing the conical bottom plate 7.

[0029] It should be noted that in this embodiment, when the electric push rod 5 drives the conical base plate 7 to move downward, the water pump sprays water through the spray pipe 19 onto the conical base plate 7 below via the reversing valve, thereby rinsing the conical base plate 7.

[0030] In one embodiment, an overflow pipe 10 is fixedly connected to one side of the sedimentation tank 1, and the other end of the overflow pipe 10 is connected to the receiving cavity 2.

[0031] It should be noted that in this embodiment, the overflow pipe 10 is located at a height higher than the outlet pipe 16 on one side of the sedimentation tank 1. When the water level inside the sedimentation tank 1 is high, water passes through the overflow pipe 10 into the receiving cavity 2 and is discharged from the bottom of the drainage funnel 3.

[0032] In one embodiment, a drain pipe 12 is fixedly connected to the bottom of the sampling box 11, and the other end of the drain pipe 12 is connected to the receiving cavity 2.

[0033] It should be noted that in this embodiment, multiple water suction pipes are installed at the bottom of the sampling box 11, which facilitates the sampling and testing of the water inside the sampling box 11 by various measuring devices. After the test is completed, the solenoid valve in the middle of the drain pipe 12 is opened, so that the water in the sampling box 11 is discharged into the drain funnel 3 through the drain pipe 12.

[0034] In one embodiment, a fixing plate 13 is fixedly connected to the bottom of the sampling box 11, and a negative pressure bottle 14 is snapped into the middle of the fixing plate 13. A solenoid valve 18 connected to the outside of the sampling box 11 is fixedly connected to the outside of the sampling box 11. The inlet of the solenoid valve 18 is connected to the bottom of the sampling box 11 through a water pipe, and the output end of the solenoid valve 18 is connected to the negative pressure bottle 14 through a water pipe.

[0035] It should be noted that in this embodiment, the negative pressure bottle 14 is a water bottle with a sealed cap on the top. The inside of the water bottle is drawn into a negative pressure, and its end is connected to a water pipe connected to the water removal end of the solenoid valve 18.
