Description

Technical Field

[0001] The invention belongs to the technical field of water pollution control, and in particular relates to a water pollution source tracing monitoring system. Background Art

[0002] With the increasing requirements for environmental protection, regulatory authorities have gradually increased the monitoring and tracing of various pollutants. The existing tracing method is mainly to trace the source through manual monitoring. The use of manual monitoring and tracing is less efficient due to the increasing concealment of pollution sources.

[0003] Due to the vast territory and numerous water bodies in my country, many factories choose to be located around natural water bodies in order to reduce production costs. The production wastewater of these factories will inevitably be discharged into the water bodies. Although the environmental protection department has put forward strict requirements and monitoring, there are still some lucky ones who will directly discharge a small amount of production wastewater during the production process.

[0004] The existing monitoring method usually adopts the method of setting up monitors around the drainage outlets reported by the manufacturer. However, for the drainage outlets set up secretly, it is not easy to be observed due to its secrecy. Once these hidden drainage outlets discharge, it will cause water pollution and ecological damage. And when the water area is large or long, the use of this fixed position detection method also has the problem of high cost.

[0005] Therefore, monitoring points similar to mobile stations have appeared in the market, which use mobile methods to continuously detect the location of pollutants and continuously take samples from the water body, thereby continuously narrowing the scope of the pollution source. However, this sampling method is prone to large errors in flowing water bodies. Pollutants flow with the water body, and the collection results at the same location at different times may change. These changes are very likely to increase the number of judgments, thereby reducing the detection efficiency of the pollution source. Summary of the invention

The sampling barrel is provided with a plurality of liquid storage tanks along the axial direction. The openings of the liquid storage tanks extend to the outside of the sampling barrel. The sampling barrel can realize two state conversions between horizontal side by side and vertical side by side with the help of the movement of the first connecting rod and the third connecting rod. The sampling barrel collects multiple sampling points in the horizontal direction of the water body at the same time with the help of the folding and unfolding mechanism.

The water pump is arranged on the second vehicle, one end of the main pipe is connected to the water pump, and the other end is connected to the secondary pipe by means of a multi-way valve, and the other end of the secondary pipe passes through the transfer tank and then enters the liquid storage tank. The secondary pipe and the liquid storage tank are arranged in a one-to-one correspondence.

[0009] As a further technical solution, the auxiliary sampling component also includes a slide plate and a second driver. The slide plate is slidably arranged on the outside of the sampling tube and is provided with a water permeable hole. The water permeable hole is connected to the liquid storage tank with the help of the sliding of the slide plate. The second driver is arranged on the second vehicle and is used to drive the slide plate to slide.

[0010] As a further technical solution, the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod have the same length and their projections on the horizontal plane can form a rhombus.

This arrangement can use multiple sampling tubes arranged side by side horizontally to quickly determine the location of pollutants in the flowing water body. Then, according to the location of the pollutants, the sampling tubes arranged side by side horizontally are transformed into sampling tubes arranged side by side vertically. After the vertical arrangement, the second vehicle needs to move until the sampling tubes arranged side by side vertically are all located on the flow trajectory of the pollutants in the water body. In this way, it is possible to further determine whether the location of the pollutants is correct and accurate, eliminating the situation where the pollutants are randomly distributed in the water body.

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] Specific implementation examples Figures 1 to 8As shown, the present invention provides a water pollution source tracing monitoring system, including a first aircraft 2 provided with a detection main station 1, a second aircraft 5 provided with a detection substation 3 and a sampling module 4, the detection substation 3, the sampling module 4 and the second aircraft 5 are all multiple, the detection main station 1 is communicatively connected to the multiple detection substations 3, the second aircraft 5 in the sampling state and the non-sampling state travel in front of and behind the first aircraft 2 respectively, the sampling module 4 includes a folding and unfolding mechanism and a first driver 6, the folding and unfolding mechanism includes four first connecting rods 7, second connecting rods 8, third connecting rods 9 and fourth connecting rods 10 which are hinged head to tail in sequence, and the first connecting rods 10, 11 and 12 are connected to the detection substations 3, and the sampling module 4 includes a folding and unfolding mechanism and a first driver 6. The first connecting rod 7 and the third connecting rod 9 are symmetrically arranged and are both provided with a sampling tube 11. The corresponding ends of the first connecting rod 7 and the third connecting rod 9 move synchronously along the first direction, and the other ends move synchronously along the second direction. The first direction and the second direction are perpendicular. The first driver 6 is used to provide power. The sampling tube 11 is provided with a plurality of liquid storage tanks 12 along the axial direction. The openings of the liquid storage tanks 12 extend to the outside of the sampling tube 11. The sampling tube 11 can realize the two state conversions of horizontal side by side and vertical side by side with the help of the movement of the first connecting rod 7 and the third connecting rod 9. The sampling tube 11 collects multiple sampling points in the horizontal direction of the water body at the same time with the help of the folding and unfolding mechanism.

[0027] Compared with the prior art, the water pollution source tracing monitoring system provided by the present invention has a detection substation 3 arranged on the second aircraft 5, a detection main station 1 arranged on the first aircraft 2, and the second aircraft 5 and the second detection substation 3 are both arranged in a one-to-one correspondence. After the initial detection, some detection substations 3 need to perform the next step of detection, and the corresponding second aircraft 5 needs to travel in front of the first aircraft 2; some detection substations 3 do not need to be detected, and the corresponding second aircraft 5 does not need to travel in front of the first aircraft 2. In order to reduce the impact on pollutants in the water body, this part of the second aircraft 5 can travel behind the first aircraft 2. The second aircraft 5 is provided with a sampling module 4, which includes a folding and unfolding mechanism and a first driver 6. The folding and unfolding mechanism includes a first connecting rod 7, a second connecting rod 8, a third connecting rod 9 and a fourth connecting rod 10 connected end to end in sequence. The first connecting rod 7 and the third connecting rod 9 are symmetrically arranged, and a sampling barrel 11 is arranged on the first connecting rod 7 and the third connecting rod 9. One end of the first connecting rod 7 and the third connecting rod 9 can move in a first direction and the other end can move in a second direction. The first direction and the second direction are perpendicular to each other. The sampling barrel 11 can be horizontally arranged side by side in the first direction and vertically arranged side by side in the second direction with the help of the folding and unfolding mechanism. In addition, the sampling barrel 11 is also provided with a plurality of liquid storage bins 12. When the liquid storage bins 12 are used for sampling, the liquid in the sampling part can enter the liquid storage bins 12. This arrangement can use multiple sampling tubes 11 arranged side by side horizontally to quickly determine the location of pollutants in the flowing water body. Then, according to the location of the pollutants, the sampling tubes 11 arranged side by side horizontally are transformed into sampling tubes 11 arranged side by side vertically. After the vertical arrangement, the second aircraft 5 needs to move until the sampling tubes 11 arranged side by side vertically are all located on the flow trajectory of the pollutants in the water body. In this way, it can be further determined whether the location of the pollutants is correct and accurate, and the situation that the pollutants are randomly distributed in the water body can be eliminated. After the location of the water pollutants is determined again, it can be measured again after driving a fixed distance. If the concentration of the pollutants at this time is greater than the result of the previous measurement, it proves that it is constantly approaching the pollution source. If the concentration of the pollutants at this time is less than the result of the previous measurement, it proves that the location of the pollution source has been passed. Then, the location of the pollutants in the water body can be relocated by driving in the opposite direction to shorten the distance. The driving distance is shortened repeatedly until the pollution source is determined within a certain range, and then it is manually searched, which can greatly improve the efficiency of the search and reduce the labor of the manual labor.

[0028] In the present invention, the detection substations 3 all include pollutant detection modules. After sample collection is completed, the sampling tubes transport several samples to the pollutant detection module for detection. Since the detection main station 1 is communicatively connected with each detection substation 3, each detection substation 3 can transmit the detection results to the detection main station 1. The detection results are compared in the detection main station 1 to determine which sampling tube in which second aircraft 5 has extracted the correct location information of the pollutant.

[0029] In the present invention, in order to reduce the influence of the water body itself, the first aircraft 2 and the second aircraft 5 can both be selected as ships.

[0030] The horizontal and vertical side-by-side arrangement mentioned in the present invention is shown in FIG. Figure 5 and Figure 6 In the case shown, both the horizontal and vertical arrangement present a certain angle, but when the connecting rod width and the sampling tube diameter are made small enough, the vertical spacing between the two rows of sampling tubes can be made as small as possible.

[0031] In this embodiment, the communication connection mode between the main detection station 1 and the detection substation 3 can be wired or wireless. The wired mode is to adopt a communication cable connection, and the wireless mode is a remote wifi connection.

[0032] like Figure 8 As shown, as a specific implementation of an embodiment of the present invention, the sampling module 4 also includes an auxiliary sampling component, which includes a water pump 13, a main pipe 14, a sub-pipe 15 and a transfer tank 16. The water pump 13 is arranged on the second aircraft 5. One end of the main pipe 14 is connected to the water pump 13, and the other end is connected to the sub-pipe 15 by means of a multi-way valve. The other end of the sub-pipe 15 passes through the transfer tank 16 and then enters the liquid storage tank 12. The sub-pipe 15 and the liquid storage tank 12 are arranged one by one.

[0033] In this embodiment, in order to facilitate sampling, the sampling module 4 is also provided with an auxiliary sampling component, which includes a water pump 13, a main pipe 14, a secondary pipe 15 and a transfer bin 16. Each sampling tube corresponds to a combing water pump 13 and a main pipe 14, each secondary pipe 15 corresponds to a liquid storage bin 12, and the transfer bin 16 is arranged on the secondary pipe 15. One end of the secondary pipe 15 penetrates into the corresponding liquid storage bin 12, and the other end is connected to the main pipe 14 by means of a multi-way. When the sampling tube reaches the designated position in the water body, the water pump 13 is pneumatically operated to sample, and the sample enters the transfer bin 16. When the amount of liquid in the transfer bin 16 reaches the detection, the water pump 13 can be stopped. Each liquid storage bin 12 corresponds to a transfer bin 16, and the pollutant detection module directly performs detection. The detection substation 3 summarizes and numbers the data and sends it to the detection main station 1, and the detection main station 1 compares and judges the data.

[0034] like Figure 8As shown, as a specific implementation of an embodiment of the present invention, the auxiliary sampling component also includes a slide plate 17 and a second driver 18. The slide plate 17 is slidably arranged on the outside of the sampling tube 11 and is provided with a water permeable hole 19. The water permeable hole 19 is connected to the liquid storage tank 12 by means of the sliding of the slide plate 17. The second driver 18 is arranged on the second aircraft 5 and is used to drive the slide plate 17 to slide.

[0035] In this embodiment, when sampling, if the liquid in the liquid storage tank 12 shows signs of flowing, the concentration of the pollutant will change. In order to avoid this situation, the auxiliary sampling component also includes a slide plate 17 and a second driver 18. The slide plate 17 is slidably arranged on the outside of the sampling tube 11. The slide plate 17 has a water-permeable hole 19. There are several water-permeable holes 19 and they are arranged at intervals. When the slide plate 17 slides, the water-permeable holes 19 can be connected with the liquid storage tank 12. At this time, the liquid can enter the liquid storage tank 12. When sampling, the slide plate 17 slides and then closes the liquid storage tank 12 to reduce the flow of the liquid as much as possible and improve the accuracy of the detection.

[0036] like Figures 3 to 7 As shown, as a specific implementation of the embodiment of the present invention, the first connecting rod 7, the second connecting rod 8, the third connecting rod 9 and the fourth connecting rod 10 have the same length and their projections on the horizontal plane can form a rhombus.

[0037] In this embodiment, in order to ensure that several sampling tubes 11 can be stably converted between horizontal side by side and vertical side by side, the lengths of the first connecting rod 7, the second connecting rod 8, the third connecting rod 9 and the fourth connecting rod 10 are set to be the same, and can form a projection on the horizontal plane. This arrangement can ensure that when switching between the two states, the end can move the same distance, thereby improving the stability of the folding expansion component.

[0038] like Figures 3 to 7 As shown, as a specific implementation of an embodiment of the present invention, there are two first drivers 6 which are respectively hinged at the hinges of the first connecting rod 7 and the fourth connecting rod 10 and the hinges of the second connecting rod 8 and the third connecting rod 9, and the driving directions of the two first drivers 6 are the same.

[0039] In this embodiment, since the lengths of the four connecting rods are consistent, the number of first drivers 6 can be set to two, and the driving end of one first driver 6 is hinged at the hinge of the first connecting rod 7 and the fourth connecting rod 10, and the driving end of the other first driver 6 is hinged at the hinge of the second connecting rod 8 and the third connecting rod 9. The driving ends of the two first drivers 6 move synchronously, so the sampling tube 11 can be switched between two states, and this power setting method greatly simplifies the overall equipment.

[0040] like Figures 3 to 7As shown, as a specific implementation of an embodiment of the present invention, the folding and unfolding mechanism also includes a bottom plate 20, the bottom plate 20 is arranged at the bottom of the second aircraft 5, the first driver 6 is arranged on the bottom plate 20, and the first connecting rod 7, the second connecting rod 8, the third connecting rod 9 and the fourth connecting rod 10 are all slidably arranged on the bottom plate 20. The first connecting rod 7 has a first connecting shaft 22 and a fourth connecting shaft 23 at both ends, that is, one end of the first connecting rod 7 is hinged to the second connecting rod 8 by means of the first connecting shaft 22, and the other end is hinged to the fourth connecting rod 10 by means of the fourth connecting shaft 23; the third connecting rod 9 has a second connecting shaft 24 and a third connecting shaft 25 at both ends, that is, one end of the third connecting rod 9 is connected to the second connecting rod 8 by means of the second connecting shaft 24, and the other end is hinged to the fourth connecting rod 10 by means of the third connecting shaft 25; the first connecting shaft 22, the second connecting shaft 24, the third connecting shaft 25 and the fourth connecting shaft 23 are all slidably arranged on the bottom plate 20

[0041] In this embodiment, in order to avoid interference between the four connecting rods during movement, the folding and unfolding mechanism also includes a bottom plate 20, which is arranged at the bottom of the second aircraft 5. The first connecting rod 7, the second connecting rod 8, the third connecting rod 9 and the fourth connecting rod 10 can be slidably arranged on the bottom plate 20, so that interference between the connecting rods can be avoided, so that the sampling tubes 11 arranged on the first connecting rod 7 and the third connecting rod 9 can be freely switched between the two states of horizontal side by side and vertical side by side. In addition, the hinge points of the first connecting shaft 22, the second connecting shaft 24, the third connecting shaft 25 and the fourth connecting shaft 23 are at different heights. From the top to the bottom, the highest one is the fourth connecting rod 10, followed by the second connecting rod 8, the first connecting rod 7 and the third connecting rod 9.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
