Description

Technical Field

[0001] The utility model belongs to the technical field of water quality monitoring, and particularly relates to a multi-parameter water quality monitoring device. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The environmental water bodies monitored mainly include surface water (rivers, lakes, reservoirs, seawater) and groundwater; including a complete ecosystem such as suspended substances, dissolved substances, sediment and aquatic organisms in water.

[0003] For large rivers, the environments where each section of the river is located are different, and the impacts on the river water are also different, which results in different water qualities in different regions of the same river. When monitoring the water quality of river water, it is necessary to sample and detect the river water in different regions, which is very inconvenient. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a water quality monitoring device that can extract river water for detection while moving in the water area, including a circular bottom plate. A plurality of cross bars are fixedly connected to the side surface of the circular bottom plate, and a floating ring is fixedly connected to one end of the cross bar. The upper surface of the circular bottom plate is fixedly installed with a circular shell through screws. A support plate is fixedly connected to the inner wall of the circular shell. A detection cylinder is fixedly connected to one side of the support plate. A multi-parameter water quality monitoring component is arranged inside the detection cylinder. A water sample treatment device is arranged below the detection cylinder. A first support plate is fixedly connected to the inner wall of the circular shell. A water pump is fixedly connected to the upper surface of the first support plate. A suction pipe and a delivery pipe are connected to the water pump. A sampling pipe is fixedly connected to the circular bottom plate. The suction pipe passes through the circular shell and is connected to the sampling pipe. The delivery pipe is connected to the detection cylinder.

[0005] In one example, the multi-parameter water quality monitoring component includes a monitoring main body and a monitoring probe. The monitoring main body is fixed on the upper surface of the support plate. A fixing plate is fixedly connected to the inner wall of the detection cylinder. The monitoring probe passes through the fixing plate and is fixedly connected to the fixing plate. The monitoring probe extends into the bottom of the detection cylinder.

[0006] In one example, the water sample treatment device includes a vertical pipe. The vertical pipe is fixed to the lower surface of the detection cylinder and is connected to the detection cylinder. The vertical pipe is L-shaped. A circular seat is fixedly connected to the outside of the vertical pipe. The vertical pipe penetrates through the circular seat. The outlet at the other end of the vertical pipe is located on the side of the circular seat. A rotating cylinder is rotatably connected to the outside of the circular seat. A plurality of output pipes are fixedly connected to the side surface of the rotating cylinder. All the output pipes are connected to the rotating cylinder. The output pipes and the outlet at the other end of the vertical pipe are on the same horizontal plane.

[0007] In one example, a second support plate is fixedly connected to a position on the inner wall of the circular housing that is symmetrical to the first support plate. A waterproof box is fixedly connected to the second support plate. An air pump is placed inside the waterproof box. An air duct on the air pump is communicated with the detection cylinder.

[0008] In one example, the lower surfaces of the first support plate and the second support plate are fixedly installed with a support plate by screws and nuts. A motor is fixedly connected to the lower surface of the support plate. A circular plate is fixedly connected to the main shaft of the motor. A plurality of circular placement grooves are provided on the upper surface of the circular plate. Preservation cans are placed in the circular placement grooves. The output pipe is in an L shape. One end of the output pipe is fixedly connected to a rubber ring. An annular card slot is provided on the lower surface of the rubber ring. The annular card slot cooperates with the preservation can.

[0009] In one example, air holes are provided on the rubber rings.

[0010] The multi-parameter water quality monitoring device proposed by the present utility model can bring the following beneficial effects:

[0011] First, by setting the floating ring and the water pump, the floating ring provides buoyancy to make the device float on the water surface. The sampling pipe is inserted into the river and moves with the water flow. During the movement, the water pump is turned on at regular intervals. The river water is pumped through the extraction pipe. The river water passes through the sampling pipe and the extraction pipe and is sent into the detection cylinder through the delivery pipe. The multi-parameter water quality monitoring component in the detection cylinder analyzes and detects it. The device floats around, and the monitoring location is different each time, achieving the purpose of random monitoring. At the same time, the river water in different environmental locations can be detected, and the detection results are more accurate. It is not necessary for the staff to routinely sample and monitor different river basins, which is more time-saving and labor-saving.

[0012] Second, by setting the preservation can, when discharging the river water in the detection cylinder, the motor drives the circular plate to rotate. The preservation can drives the rotating cylinder to rotate through the rubber ring. The output pipe is aligned with the vertical pipe. The river water enters the preservation can through the output pipe for preservation. Then the motor drives the rotating cylinder to rotate again to block the vertical pipe for the second detection. The detected river water is discharged into the adjacent preservation can, and so on. After each detection, the water sample during the detection will be stored separately, which is convenient for subsequent detection experiments. Description of the Drawings

[0024] Such as Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a multi-parameter water quality monitoring device, which includes: a circular bottom plate 1, a plurality of cross bars 2 are fixedly connected to the side surface of the circular bottom plate 1, one end of the cross bar 2 is fixedly connected to a floating ring 3, the upper surface of the circular bottom plate 1 is fixedly installed with a circular housing 4 through screws, a support plate 5 is fixedly connected to the inner wall of the circular housing 4, a detection cylinder 6 is fixedly connected to one side of the support plate 5, a multi-parameter water quality monitoring component 7 is arranged inside the detection cylinder 6, a water sample treatment device 8 is arranged below the detection cylinder 6, a first support plate 9 is fixedly connected to the inner wall of the circular housing 4, a water pump 10 is fixedly connected to the upper surface of the first support plate 9, an extraction pipe 11 and a delivery pipe 13 are communicated with the water pump 10, a sampling pipe 12 is fixedly connected to the circular bottom plate 1, the extraction pipe 11 passes through the circular housing 4 and is communicated with the sampling pipe 12, and the delivery pipe 13 is communicated with the detection cylinder 6. The device is placed in a river, and a GPS is placed inside the device. The floating ring 3 provides buoyancy to make the device float on the water surface. The sampling pipe 12 is inserted into the river and moves with the water flow. During the movement, at regular intervals, the water pump 10 is turned on, and river water is extracted through the extraction pipe 11. The river water passes through the sampling pipe 12 and the extraction pipe 11, and is sent into the detection cylinder 6 through the delivery pipe 13, and is analyzed and detected by the multi-parameter water quality monitoring component 7 in the detection cylinder 6. After the detection, the specific detection process is a common technical means in the art, so it will not be elaborated in this application. It is processed by the water sample treatment device 8 below the detection cylinder 6 and waits for the next extraction and detection. The device floats around, and the monitoring location is different each time, achieving the purpose of random monitoring. At the same time, the river water in different environmental locations can be detected, and the detection results are more accurate. With this device, it is not necessary for staff to conduct routine sampling and monitoring of different river basins, which is more time-saving and labor-saving. When retrieving the device, just wait for the device to be washed ashore by the water flow and find it through the GPS.

[0025] Specifically, the multi-parameter water quality monitoring component 7 includes a monitoring main body 71 and a monitoring probe 72. The monitoring main body 71 is fixed on the upper surface of the support plate 5. A fixing plate 73 is fixedly connected to the inner wall of the detection cylinder 6. The monitoring probe 72 passes through the fixing plate 73 and is fixedly connected to the fixing plate 73. The monitoring probe 72 extends into the bottom of the detection cylinder 6. The monitoring main body 71 is located outside the detection cylinder 6, and the detection probe is located inside the detection cylinder 6. During detection, only the monitoring probe 72 extends into the bottom of the detection cylinder 6 to contact the river water. The river water is enclosed in the detection cylinder 6, which can prevent the monitoring main body 71 from being affected by moisture. The monitoring probe 72 extends into the bottom of the detection cylinder 6. Each time a small amount of river water is extracted into the detection cylinder 6, it can contact the monitoring probe 72 for monitoring, saving water resources and avoiding waste.

[0026] Specifically, the water sample treatment device 8 includes a vertical pipe 81 fixed to the lower surface of the detection cylinder 6. The vertical pipe 81 is communicated with the detection cylinder 6. The vertical pipe 81 is L-shaped. A circular seat 82 is fixedly connected to the outside of the vertical pipe 81. The vertical pipe 81 penetrates through the circular seat 82. The outlet at the other end of the vertical pipe 81 is located on the side of the circular seat 82. A rotating cylinder 83 is rotatably connected to the outside of the circular seat 82. A plurality of output pipes 84 are fixedly connected to the side surface of the rotating cylinder 83. All the output pipes 84 are communicated with the rotating cylinder 83. The output pipes 84 and the outlet at the other end of the vertical pipe 81 are on the same horizontal plane. After the detection process in the detection cylinder 6 is completed, at this time, rotate the rotating cylinder 83 to connect the vertical pipe 81 originally facing the inner wall of the rotating cylinder 83 with the output pipe 84. The river water in the detection cylinder 6 and the vertical pipe 81 flows out of the detection cylinder 6 through the output pipe 84, avoiding occupying the detection cylinder 6 and affecting the next detection. Before the next extraction of river water into the detection cylinder 6, rotate the rotating cylinder 83 to make the vertical pipe 81 face the inner wall of the rotating cylinder 83 again, blocking the vertical pipe 81, so that the river water can stay in the detection cylinder 6, facilitating the monitoring probe 72 to perform detection and analysis.

[0027] Specifically, a second support plate 14 is fixedly connected to the position on the inner wall of the circular housing 4 symmetric to the first support plate 9. A waterproof box 15 is fixedly connected to the second support plate 14. An air pump is placed in the waterproof box 15. The air guide pipe on the air pump is communicated with the detection cylinder 6. When discharging the river water in the detection cylinder 6, the air pump injects gas into the detection cylinder 6 to blow out the remaining water droplets in the detection cylinder 6 and the vertical pipe 81, reducing the residue and avoiding affecting the water sample of the next detection.

[0028] Specifically, the lower surfaces of the first support plate 9 and the second support plate 14 are fixedly installed with a support plate 16 through screws and nuts. A motor 17 is fixedly connected to the lower surface of the support plate 16. The main shaft of the motor 17 is fixedly connected to a circular plate 18. A plurality of circular placement grooves are provided on the upper surface of the circular plate 18. Preservation cans 19 are placed in the circular placement grooves. The output pipe 84 is L-shaped. One end of the output pipe 84 is fixedly connected to a rubber ring 20. An annular clamping groove is provided on the lower surface of the rubber ring 20. The annular clamping groove is matched with the preservation can 19. During installation, the upper end of the preservation can 19 is clamped in the annular clamping groove in the rubber ring 20. The screws on the lower surfaces of the first support plate 9 and the second support plate 14 pass through the support plate 16 and are fixed by nuts. When discharging the river water in the detection cylinder 6, the motor 17 drives the circular plate 18 to rotate. The preservation can 19 drives the rotating cylinder 83 to rotate through the rubber ring 20, aligning the output pipe 84 with the vertical pipe 81. The river water enters the preservation can 19 through the output pipe 84 for preservation. Then the motor 17 drives the rotating cylinder 83 to rotate again, blocking the vertical pipe 81 for the second detection. The detected river water is discharged into the adjacent preservation can 19, and so on. After each detection, the water sample during the detection will be preserved, facilitating subsequent detection tests. When the device is retrieved, disassemble the circular housing 4, unscrew the nuts, and take out the motor 17, the support plate 16, the circular plate 18, and the circular plate 18 together.

[0029] Specifically, air holes 21 are provided on all the rubber rings 20. The air holes 21 communicate the storage tank 19 with the outside, preventing the rubber ring 20 from detaching from the storage tank 19 when the air pump injects gas.

[0030] Working principle: Place the device in a river. The floating ring 3 provides buoyancy to make the device float on the water surface. The sampling pipe 12 is inserted into the river and moves with the water flow. During the movement, at regular intervals, the water pump 10 is turned on, and river water is pumped through the extraction pipe 11 into the detection cylinder 6 for detection (specific detection steps are common technical means in this field and will not be elaborated here). After the detection is completed, the motor 17 drives the circular plate 18 to rotate, and the storage tank 19 drives the rotating cylinder 83 to rotate through the rubber ring 20. The river water enters the storage tank 19 through the output pipe 84 for storage. The air pump injects gas into the detection cylinder 6 to blow the remaining water droplets in the detection cylinder 6 and the vertical pipe 81 into the storage tank 19. When the river water is injected into the detection cylinder 6 for detection, the vertical pipe 81 is opposite to the inner wall of the rotating cylinder 83, blocking the vertical pipe 81.
