Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a surface water quality monitoring device. Background Art

[0002] Surface water refers to the general term for dynamic water and static water on the land surface, also known as "land water", including various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, ice sheets, etc. It is one of the important sources of human domestic water and also the main component of the water resources of each country. Most of the domestic water used by residents in China is surface water of the lake reservoir type, so the monitoring of its water quality is particularly important.

[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number CN220323281U is that after the teeth on the rotating ring are separated from the positioning support body, the positioning support body is driven to reset by the torsion performance of the torsion spring. At this time, the surface water in the container inside the positioning support body will fluctuate clockwise and counterclockwise to form a flow, so that the surface water can always be in a flowing state during monitoring, thereby reducing the disadvantage that the particulate matter precipitates during the monitoring of the surface water stationary in the container and causing inaccurate measurement data, and improving the simplicity of the surface water monitoring measurement through this method.

[0004] However, this device still has deficiencies: after the device is fixed, its height remains unchanged. Once a flood season occurs and the water surface height changes significantly, the entire device will be flooded and damaged, thus failing to achieve the monitoring purpose.

A drain pipe 7 communicating with the outside is provided at the bottom of the water storage bucket 6, and a solenoid valve 8 for controlling the on-off inside it is provided in the drain pipe 7.

A wireless module and a controller are provided inside the chassis 1. The controller is electrically connected to the analyzer, and the wireless module is electrically connected to the controller. The wireless module is remotely communicatively connected to a monitoring center. The solenoid valve 8 is electrically connected to the controller, and a liquid level sensor 20 is provided inside the water storage bucket 6. The liquid level sensor 20 is electrically connected to the controller. The sampling component includes a connecting pipe 13 and a water pump 18. A bracket 11 is provided inside the chassis 1. The bracket 11 rotatably connects a hollow roller 12 with an opening at one end. The connecting pipe 13 is wound around the hollow roller 12, and one end of the connecting pipe 13 is inserted into the hollow roller 12 and communicates with its interior. The other end of the connecting pipe 13 communicates with a weighted filter head 14. A motor A17 for driving the hollow roller 12 to rotate is provided on the bracket 11. The water pump 18 is located inside the chassis 1. A suction pipe is provided at the input end of the water pump 18. The other end of the suction pipe is inserted into the hollow roller 12 and is rotatably connected to its inner wall. The output end of the water pump 18 communicates with a water outlet pipe 19. The other end of the water outlet pipe 19 is inserted into the water storage bucket 6. The water pump 18 is electrically connected to the controller. A through hole A101 is provided on the bottom plate of the chassis 1, and a through hole B201 corresponding to the through hole A101 is provided on the floating platform 2. A slider 15 is slidably arranged in the through hole A101. A square hole is provided on the slider 15.

When water quality needs to be detected, the motor A17 drives the hollow roller 12 to rotate, thereby slowly releasing the connecting pipe 13. The pipe orifice of the connecting pipe 13 sinks under the gravity of the weight filter head 14. At this time, the roller measuring instrument 16 measures the sinking depth of the connecting pipe 13. When the first measurement depth is reached, the motor A17 pauses. At this time, the water pump 18 starts to pump water. Before the water pump 18 pumps water, the solenoid valve 8 is opened first. The water in the connecting pipe 13 in the early stage directly drains out after entering the water storage bucket 6. After draining for a certain period of time, the solenoid valve 8 closes. Then the water entering the water storage bucket 6 remains inside. When the liquid level sensor 20 detects that the water level reaches the detection depth, the water pump 18 pauses, and the detection probe 10 starts to detect the water quality. The detection result is fed back to the analyzer. After the analyzer analyzes the data, it feeds the data back to the controller. The controller feeds the data back to the remote monitoring center through the wireless module. Subsequently, the solenoid valve 8 is opened, and the water in the water storage bucket 6 is drained. Then the pipe orifice of the connecting pipe 13 continues to sink and reaches the second detection depth. Just repeat the above actions and detections.
