Description

Technical Field

[0001] The present invention relates to the field of water quality monitoring, and in particular to an online surface water quality monitoring device and a monitoring method thereof. Background Art

[0002] As an important means of modern water resource protection, the online water quality monitoring device integrates automatic analytical instruments, sensor technology, automatic measurement and control, computer application technology and special software to form a comprehensive online monitoring system. The device is designed to capture water quality anomalies in a timely manner, quickly warn of downstream pollution risks, track pollution sources, and provide real-time and accurate data support for water quality management decisions.

[0003] When the existing online water quality monitoring device samples and monitors the water body, there is a risk of sample contamination and dilution in the process of the sampling structure salvaging the water at the sampling point; secondly, the salvaged water samples will volatilize, deteriorate, diffuse, etc. under the influence of factors such as oxygen and sunlight, so the sampling equipment is best to be carried out below the water body and reduce the sampling time of the sample. At the same time, during the sampling process, the traditional sampling structure will stir the water body when passing through different layers of water bodies, which will cause the water body around the device to mix easily. At this time, the sampling structure will cause inaccurate monitoring results due to the inclusion of different layers of water bodies. And after the water body is sampled, the separation of the water body and the sampling structure is not only troublesome, but also affects the next monitoring result due to incomplete separation, making the monitoring results generated by the traditional monitoring device unstable and inaccurate.

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] refer to Figures 1 to 12 , a surface water quality online monitoring device, comprising:

[0044] A top cover 2 loaded with a solar cell 1;

[0045] A support frame 3 is fixedly connected to the lower end of the top cover 2;

[0046] Flow regulating mechanism 4 (such as Figure 8 As shown), connected to the top cover 2, including a positioning cone 7, a constant flow pipe 5, a water collecting pipe 19, a plurality of positioning sleeves 8 and a plurality of adapter sleeves 10, the constant flow pipe 5 is coaxially fixedly connected to the lower end of the top cover 2, a plurality of positioning sleeves 8 are arranged in the constant flow pipe 5 in sequence at equal intervals, a plurality of positioning sleeves 8 are coaxially fixedly connected to the constant flow pipe 5, a plurality of adapter sleeves 10 are rotatably arranged at the ends of the plurality of positioning sleeves 8, a positioning cone 7 is fixedly arranged below the constant flow pipe 5, and the water collecting pipe 19 is coaxially slidably arranged inside the constant flow pipe 5 and can collect water;

[0047] The flow conversion mechanism 35 is arranged inside the top cover 2 and can drive the corresponding adapter sleeve 10 to rotate through the water collecting pipe 19;

[0048] An air pump 42, connected to the top cover 2 and capable of delivering gas into the water collecting pipe 19;

[0049] The mini sampler 43 is fixedly connected to the inside of the water collecting pipe 19 and can monitor the water inside the water collecting pipe 19 .

[0050] When the device is in operation, after the operator places the support frame 3 in the monitoring area, the flow-regulating mechanism 4 drives the water collecting pipe 19 to move along the axial direction of the flow-regulating pipe 5 until the water collecting pipe 19 moves to the water area of ​​the water body to be sampled. At this time, the flow-converting mechanism 35 drives the corresponding adapter sleeve 10 to rotate through the water collecting pipe 19. At this time, the water body of the corresponding layer will pass through the flow-regulating pipe 5 and the adapter sleeve 10 in turn and then flow into the water collecting pipe 19, and the mini sampler 43 located in the water collecting pipe 19 can monitor the water body. When the sample needs to be replaced, the flow-converting mechanism 35 first drives the corresponding adapter sleeve 10 to reset through the water collecting pipe 19, and then the water collecting pipe 19 will separate the sampled water body and the external water body. At this time, the air pump 42 will start and send the water body in the water collecting pipe 19 out of the water collecting pipe 19, thereby avoiding the residual water inside the water collecting pipe 19 affecting the next monitoring result.

[0051] In order to distinguish different levels of water bodies during sampling, the following features are set:

[0052] A number of constant flow holes 6 are symmetrically formed at equal intervals on the side wall of the constant flow pipe 5, a number of limit grooves 9 are formed at equal angles along the circumferential direction on the positioning sleeve 8, two limit flanges 20 are symmetrically formed on the outer edge of the water collecting pipe 19, the limit flanges 20 are slidably connected to the corresponding limit grooves 9, a number of limit ribs 12 corresponding to the limit flanges 20 are formed at equal angles along the circumferential direction on the inner edge of the adapter sleeve 10, the limit ribs 12 are slidably connected to the limit flange 20, the number of the limit grooves 9 is greater than the number of the limit ribs 12, and the two can be aligned, the adapter sleeve 10 is symmetrically formed with two guide holes 11 along the circumferential direction, and the guide holes 11 are connected to the corresponding constant flow holes 6. When it is necessary to drive the constant flow hole 6 and the guide hole 11 to be coaxially aligned so that the water body can flow through the constant flow tube 5, the flow conversion mechanism 35 will drive the water collecting pipe 19 to rotate. After the limiting flange 20 on the water collecting pipe 19 and the limiting rib 12 on the adapter sleeve 10 are engaged, the rotation of the water collecting pipe 19 will drive the corresponding adapter sleeve 10 to rotate. Subsequently, the water body will flow into the water collecting pipe 19 through the constant flow hole 6 and the guide hole 11 in turn (the connection process between the water collecting pipe 19 and the adapter sleeve 10 will be explained later), so that the mini sampler 43 in the water collecting pipe 19 can monitor the water body.

[0053] In order to facilitate the water inside the water collecting pipe 19 to be discharged from the water collecting pipe 19, the following features are also specifically provided:

[0054] The lower end of the water collecting pipe 19 is formed with a plurality of leaking holes 21 at equal intervals along the circumferential direction. When the water needs to leave the water collecting pipe 19, the air pump 42 will send air into the water collecting pipe 19, and then the air will squeeze the water from top to bottom so that the water passes through the plurality of leaking holes 21 and leaves the water collecting pipe 19.

[0055] In order to prevent the water in the water collecting pipe 19 from flowing back, the following features are also specifically provided:

[0056] The flow-regulating mechanism 4 also includes a second one-way valve 14 and two first one-way valves 13. The two first one-way valves 13 are symmetrically arranged on both sides of the water collecting pipe 19. The two first one-way valves 13 can prevent the water in the water collecting pipe 19 from flowing back to the adapter sleeve 10. The second one-way valve 14 is fixedly connected to the upper end of the water collecting pipe 19. The second one-way valve 14 can prevent the water in the water collecting pipe 19 from flowing back to the upper part of the water collecting pipe 19. When the water flows into the water collecting pipe 19 through the flow-regulating hole 6 and the guide hole 11 in sequence, the two first one-way valves 13 can prevent the water in the water collecting pipe 19 from flowing back to the direction of the adapter sleeve 10, and the water remaining between the water collecting pipe 19 and the adapter sleeve 10 will flow downward from the limit groove 9 (reference here to Figure 4 ,like Figure 4 As shown in the middle limiting groove 9, when the limiting rib 12 formed on the inner side of the adapter sleeve 10 and the limiting groove 9 formed on the inner side of the positioning sleeve 8 are aligned, the redundant limiting groove 9 is used to divert the water) to prevent excessive water from remaining inside the constant flow tube 5.

[0057] In order to drive the water collecting pipe 19 to move, the following features are also specifically provided:

[0058] The flow-fixing mechanism 4 further includes a power motor 31, a movable baffle 22, a power gear 30, a transfer gear ring 29, two positioning tubes 32, two transfer gears 28, two first bevel teeth 26, two second bevel teeth 27, four traction wheels 25, two positioning baffles 33, two traction ropes 23 and two tensioners 24. The movable baffle 22 is coaxially fixedly connected to the lower end of the flow-fixing tube 5, wherein two traction wheels 25 are arranged at the lower end of the movable baffle 22, and the remaining two traction wheels 25 are arranged inside the top cover 2. The power motor 31 is fixedly arranged inside the top cover 2 through a motor frame, and the power gear 30 is fixedly connected to the output end of the power motor 31 (such as Fig.10 As shown, the transfer gear ring 29 is rotatably arranged beside the power gear 30 and meshes with the power gear 30, the two transfer gears 28 are rotatably arranged on the inner side of the transfer gear ring 29 through the gear seat, the two transfer gears 28 are meshed with the transfer gear ring 29, the two first bevel teeth 26 are respectively coaxially fixedly connected with the two transfer gears 28, the two second bevel teeth 27 are respectively meshed with the two first bevel teeth 26, the two second bevel teeth 27 are respectively coaxially fixedly connected with the remaining two traction wheels 25, and the two ends of the traction rope 23 are respectively transmission-connected with the two traction wheels 25 on the same side of the constant flow tube 5 (as shown in FIG. Figure 5 As shown in the figure, two positioning tubes 32 are respectively arranged on both sides of the constant flow tube 5, and the two positioning tubes 32 are respectively coaxially sleeved with one side of the traction rope 23 located outside the constant flow tube 5. The upper end of the positioning tube 32 is fixedly connected to the top cover 2, and the lower end is fixedly connected to the tensioner 24. The tensioner 24 is connected to the traction rope 23 and can keep the traction rope 23 in a taut state. The two positioning baffles 33 are respectively rotatably connected to the upper and lower ends of the water collecting pipe 19 (as shown in the figure). Fig.11 As shown in the figure, the two positioning baffles 33 are respectively formed with a number of positioning ribs 34 along the circumferential direction, and the positioning ribs 34 are slidably connected to the number of limit grooves 9. The two traction ropes 23 are located on one side of the fixed flow tube 5 and are fixedly connected to the two positioning baffles 33 in turn. When the position of the water collecting pipe 19 needs to be changed, the power motor 31 is started and drives the transfer gear ring 29 to rotate through the power gear 30. The transfer gear ring 29 drives the two first bevel teeth 26 to rotate through the two transfer gears 28. The two first bevel teeth 26 will drive the two traction wheels 25 located above to rotate through the corresponding second bevel teeth 27. Then, under the action of the traction rope 23, the traction rope 23 will drive the water collecting pipe 19 to move through the two positioning baffles 33. In this process, the tensioner 24 can ensure that the traction rope 23 is tightened to prevent the traction rope 23 from being loosened, causing the water collecting pipe 19 to be unable to align with the corresponding transfer sleeve 10.

[0059] In order to drive the water collecting pipe 19 to rotate, and then drive the adapter sleeve 10 to rotate through the water collecting pipe 19, so that the flow guide hole 11 on the adapter sleeve 10 is connected with the constant flow hole 6 on the constant flow pipe 5, the following features are also specifically provided:

[0060] The commutation mechanism 35 includes a telescopic tube 36, a driving motor 37, a driving gear 38 and a telescopic gear 39. The driving motor 37 is arranged inside the top cover 2 and is fixedly connected to the top cover 2 through a motor frame. The driving gear 38 is fixedly connected to the output end of the driving motor 37 coaxially. The telescopic gear 39 meshes with the driving gear 38 and is rotatably connected to the top cover 2. The lower end of the telescopic tube 36 is fixedly connected to the water collecting pipe 19, and the upper end is fixedly connected to the telescopic gear 39 coaxially. After the driving motor 37 is started, the driving motor 37 will drive the telescopic gear 39 to rotate through the driving gear 38. After the telescopic gear 39 rotates, it will drive the water collecting pipe 19 to rotate through the telescopic tube 36. Since the limiting flange 20 on the water collecting pipe 19 and the limiting rib 12 on the adapter sleeve 10 are engaged (reference here Figure 3 and Figure 4 ), so the water collecting pipe 19 will drive the adapter sleeve 10 to rotate during the rotation process until the guide hole 11 and the constant flow hole 6 are aligned, and the water will flow into the water collecting pipe 19 after passing through the constant flow hole 6, the guide hole 11 and the first one-way valve 13 in sequence.

[0061] In order to release the water inside the water collecting pipe 19, the following features are also specifically provided:

[0062] The flow-regulating mechanism 4 also includes a positioning chassis 15, a positioning spring 17 and a positioning top plate 18. The positioning chassis 15 is arranged below the water collecting pipe 19 and is coaxially fixedly connected to the positioning baffle 33. A liquid collecting hole 16 is formed in the middle of the positioning chassis 15. The lower end of the positioning spring 17 is coaxially fixedly connected to the positioning chassis 15. The positioning top plate 18 is coaxially fixedly connected to the upper end of the positioning spring 17. The upper end of the positioning top plate 18 is against the lower end of the water collecting pipe 19. When the air pump 42 pumps the gas into the water collecting pipe 19 through the telescopic tube 36, the gas will squeeze the water in the water collecting pipe 19 from top to bottom. At this time, under the action of the second one-way valve 14 and the two first one-way valves 13, the water in the water collecting pipe 19 will pass through a number of leakage holes 21 and then push the positioning top plate 18 to move. After the positioning top plate 18 moves, the water will flow downward from the liquid collecting hole 16 of the positioning bottom plate 15, thereby realizing the cleaning of the water in the water collecting pipe 19 and preventing confusion of water bodies between different levels in the subsequent monitoring process.

[0063] In order to ensure that the water discharged from the water collecting pipe 19 can be discharged from the constant flow pipe 5, the following features are also specifically provided:

[0064] The flow conversion mechanism 35 also includes a flow deflector 41 and a plurality of third one-way valves 40. The flow deflector 41 is sleeved on the lower end of the movable baffle 22 and is fixedly connected to the positioning cone 7. The plurality of third one-way valves 40 are arranged in an array at equal angles along the circumferential direction of the flow deflector 41. After the air pump 42 squeezes the water in the water collecting pipe 19 out of the water collecting pipe 19, the water will flow downward and fall into the flow deflector 41. Then, the third one-way valve 40 arranged on the flow deflector 41 can guide the water into the water area to prevent the water from being retained in the constant flow pipe 5.

[0065] A monitoring method of an online surface water quality monitoring device, further comprising the following steps:

[0066] S1: The operator first places the device as a whole in the water area to be monitored. At this time, the solar cell 1 can provide energy for the operation of the device, and the positioning cone 7 can be inserted into the formation to ensure that the device will not move;

[0067] S2: After the water body is stable, the operator starts the device and drives the water collecting pipe 19 to move to the corresponding layer of the water body, and then the flow conversion mechanism 35 starts and drives the water collecting pipe 19 to rotate to ensure that the water can flow into the water collecting pipe 19;

[0068] S3: After the water flows into the water collecting pipe 19, it will be sampled and monitored by the mini sampler 43. After the sampling is completed, the air pump 42 starts and pushes the water in the water collecting pipe 19 out of the water collecting pipe 19.

[0069] The working principle of the device is that after the operator places the support frame 3 in the monitoring area, the power motor 31 starts and drives the two positioning baffles 33 to move through the traction rope 23. The two positioning baffles 33 will drive the water collecting pipe 19 to move along the axial direction of the constant flow pipe 5 until the water collecting pipe 19 moves to the water area of ​​the water body to be sampled. At this time, the driving motor 37 drives the water collecting pipe 19 to rotate through the telescopic tube 36, and the water collecting pipe 19 drives the corresponding adapter sleeve 10 to rotate. At this time, the water body of the corresponding layer will pass through the constant flow pipe 5 and the adapter sleeve 10 in turn and then flow into the water collecting pipe 19, and the mini sampler 43 located in the water collecting pipe 19 can monitor the water body. When the sample needs to be replaced, the driving motor 37 will drive the telescopic tube 36 to rotate, and then the telescopic tube 36 will first drive the corresponding adapter sleeve 10 to reset through the water collecting pipe 19. At this time, the water collecting pipe 19 will separate the sampled water body and the external water body. Finally, after the air pump 42 is started, the water body in the water collecting pipe 19 will be sent out of the water collecting pipe 19, thereby avoiding the residual water inside the water collecting pipe 19 affecting the next monitoring result.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
