[0012] In addition, the present invention also discloses a monitoring method for the real-time monitoring device for the water environment in the Yangtze River Basin, which comprises the following steps:

[0013] S1: The water is pumped into the water inlet pipe through the water pump, and then discharged to the top of the sampling box through the water outlet pipe. The water discharged through the water outlet pipe falls onto the filter net, and then flows into the sampling box after being filtered by the filter net;

[0014] S2: The water entering the sampling box gradually contacts the monitoring probe to monitor the water quality. At the same time, when the water in the sampling box rises and gradually contacts the monitoring probe, the float starts to rise in the sampling box, thereby pushing the lower end of the connecting rod to move, so that the upper end of the connecting rod pushes the filter screen and the support rod to rotate counterclockwise along their rotating shaft, and then gradually tilts and lifts. At this time, during the process of filtering water by the filter screen, part of the water falling on the inclined filter screen drives the impurities to flow and leave the filter screen, and the other part of the water passes through the filter screen and enters the sampling box;

[0015] S3: As the float gradually rises and pushes the filter to rotate counterclockwise, the float pulls the soft steel rope upward, thereby pulling the chain downward, causing the first sprocket and the second sprocket to rotate, thereby driving the disc to rotate, driving the connecting column to move back and forth, causing one end of the connecting column to drive the rack to slide back and forth in the slide rail, and finally driving the gear to rotate back and forth, causing the cleaning brush to rotate back and forth on the outer wall of the monitoring probe to clean the monitoring probe;

[0016] S4: When the monitoring is completed, the remote control switch usually energizes the solenoid valve tube to open and drain the water in the sampling box.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. When monitoring water quality, the present invention starts the water pump of the sampling mechanism through the remote control switch to pump water into the filter net of the filtering mechanism, so that the filter net filters the water and then enters the sampling box to contact the monitoring probe, and then starts the monitoring instrument body through the remote control switch to automatically monitor the water quality;

[0019] 2. When the water in the sampling box of the present invention gradually rises, the buoyancy causes the float ball of the buoyancy mechanism to gradually rise, so that the connecting rod pushes the filter screen to rotate counterclockwise, and the filter mechanism and the buoyancy mechanism are linked together, so that the filter screen gradually tilts and lifts during the process of filtering water, so that the impurities on the filter screen are separated with a part of the water flow, which is conducive to the filter screen to continue filtering water, and realize the self-cleaning process;

[0020] 3. In the process of the floating ball rising, the chain of the driving mechanism can be pulled down to make the second chain rotate to drive the disc of the shaking mechanism to rotate. During the rotation of the disc, the connecting column of the cleaning mechanism is moved to push the rack to slide back and forth, and the buoyancy mechanism, the shaking mechanism and the cleaning mechanism are pulled up. During the reciprocating movement of the rack, the gear is driven to rotate back and forth, so that the cleaning brush reciprocates on the outer wall of the monitoring probe to clean the monitoring probe, which is beneficial for the monitoring probe to contact with the water in the sampling box, realizes the self-cleaning function, and prevents impurities from adhering to the surface of the monitoring probe and affecting the measurement results;

[0021] 4. After the monitoring instrument of the present invention monitors the water quality, the water quality monitoring data is transmitted to the remote terminal module through the GPS and WiFi of the data transmission module. The data is displayed on the display screen of the remote terminal module for personnel to refer to. There is no need for personnel to go to the water environment of the Yangtze River Basin to take samples and monitor the water quality, which simplifies the sampling and monitoring process and improves the monitoring efficiency.

[0031] A real-time monitoring device for the water environment in the Yangtze River Basin, comprising a sampling box 1, wherein a monitoring instrument body 9 for water quality monitoring is fixed in the sampling box 1, and the monitoring instrument body 9 is connected to a monitoring probe 8 for monitoring water quality, the sampling box 1 cooperates with a sampling mechanism 2 for pumping water, and a filtering mechanism 3 is provided between the sampling mechanism 2 and the sampling box 1, and is characterized in that: a buoyancy mechanism 4 for cleaning the filtering mechanism 3 and a cleaning mechanism 7 for cleaning the monitoring probe 8 are provided in the sampling box 1, the filtering mechanism 3 and the cleaning mechanism 7 are both cooperated with a shaking mechanism 6, and the shaking mechanism 6 and the buoyancy mechanism 4 are connected by a driving mechanism 5, and an electromagnetic valve tube 11 for drainage is fixed through one side of the sampling box 1.

[0032] Preferably, the sampling mechanism 2 includes a water pump 21, and the water pump 21 is fixed with a water inlet pipe 22 and a water outlet pipe 24. The outer wall of the water inlet pipe 22 is fixedly connected to a fixed seat 23, and the end of the fixed seat 23 is fixedly connected to the outer wall of the sampling box 1. The water outlet end of the water outlet pipe 24 is located above the sampling box 1.

[0033] Preferably, the filtering mechanism 3 includes a filter screen 31, one end of which is fixedly connected to a support rod 32, and the support rod 32 is rotatably connected to the outer wall of the water inlet pipe 22 via a rotating shaft 33, and the filter screen 31 is located below the water outlet end of the water outlet pipe 22. In this embodiment, the water discharged from the water outlet pipe 24 falls onto the filter screen 31, is filtered by the filter screen 31 and flows into the sampling box 1 to sample the water to be monitored, and the water entering the sampling box 1 contacts the monitoring probe 8, and the water quality is monitored in real time when the monitoring instrument body 9 is powered on.

[0034] Preferably, the buoyancy mechanism 4 includes a floating ball 41, and a slide groove 43 is vertically provided on the inner wall of the sampling box 1. The floating ball 41 and the slide groove 43 are slidably matched. The upper end of the floating ball 41 is rotatably connected with a connecting rod 42, and the upper end of the connecting rod 42 is rotatably connected with the lower end of the filter screen 31. In this embodiment, the filter screen 31, the connecting rod 42, and the floating ball 41 constitute a crank connecting rod mechanism; when the filtered water enters the sampling box 1 and rises gradually to contact the monitoring probe 8, the floating ball 41 begins to rise and float in the sampling box 1, pushing the lower end of the connecting rod 42 to move, so that the upper end of the connecting rod 42 pushes the filter screen 31 and the support rod 32 to rotate counterclockwise and gradually tilt and lift. At this time, during the process of filtering water by the filter screen 31, a part of the water falling on the inclined filter screen 31 drives the impurities to flow away from the filter screen 31, and a part of the water passes through the filter screen 31 into the sampling box 1, so that the filter screen 31 is cleaned in the process of continuing to add water in the sampling box 1, which is convenient for sampling.

[0035] Preferably, the shaking mechanism 6 includes a disc 62, which is rotatably connected to the inside of the sampling box 1, a scraper 63 is fixedly connected to the outer wall of the disc 62, and a semicircular ring 61 matched with the scraper 63 is fixedly connected to the lower end of the filter 31. When less water enters the sampling box 1 and the float 41 is at a lower position, the disc 62 rotates to make the scraper 63 constantly contact the semicircular ring 61, and under the action of the scraper 63 and gravity, the semicircular ring 61 and the filter 31 reciprocate slightly, which is conducive to the water quickly passing through the filter 31 and entering the sampling box 1.

[0036] Preferably, the driving mechanism 5 includes a chain 51, one end of the disc 62 is fixedly connected to a second sprocket wheel 53, the chain 51 is meshingly connected to the second sprocket wheel 53, the inner wall of the sampling box 1 is rotatably connected to a first sprocket wheel 52 arranged on one side of the float 41, the first sprocket wheel 52 is meshingly connected to the chain 51, the lower end of the chain 51 is fixedly connected to a soft steel rope 54, one end of the soft steel rope 54 is fixedly connected to the outer wall of the float 41, the upper end of the chain 51 is fixedly connected to a vertically arranged counterweight block 55, and the counterweight block 55 is suspended inside the sampling box 1. As the float 41 gradually rises and pushes the filter screen 31 to rotate counterclockwise, the float 41 rises and pulls the soft steel rope 54 upward, pulling down the chain 51, so that the first sprocket 52 and the second sprocket 53 rotate, thereby driving the disc 62 and the scraper 63 to rotate. When the filter screen 31 rotates and tilts and the scraper 63 can still touch the semicircular ring 61, the rotation of the scraper 63 can push the semicircular ring 61 and the filter screen 31 to rotate and lift slightly, until the filter screen 31 rotates and moves upward counterclockwise, and the scraper 63 cannot touch the semicircular ring 61. At this time, some water has entered the sampling box 1.

[0037] Preferably, the cleaning mechanism 7 includes a gear 72, the outer wall of the upper end of the monitoring probe 8 is rotatably connected to the center of the gear 72, a slide rail 75 is fixed to the inner wall of the sampling box 1, a rack 71 is slidably connected in the slide rail 75, one end of the rack 71 is rotatably connected to one end of a connecting column 74, the other end of the connecting column 74 is rotatably connected to the disc 62, the lower end of the gear 72 is fixedly connected to the top of a cleaning brush 73, the cleaning brush 73 is a semicircular ring structure, and the cleaning brush 73 is wrapped around the outer wall of the monitoring probe 8. In this embodiment, the disk 62, the connecting column 74 and the rack 71 constitute a crank slider mechanism; when the disk 62 is pulled and rotated by the chain 51, the connecting column 74 is driven to move, so that the right end of the connecting column 74 drives the rack 71 to slide back and forth in the slide rail 75, driving the gear 72 to rotate back and forth, so that the three cleaning brushes 73 respectively rotate back and forth on the outer walls of the three monitoring probes 8 to clean the monitoring probes 8, which is conducive to the monitoring probes 8 contacting with the water in the sampling box 1 for monitoring. At the same time, the cleaning brush 73 with a semi-circular ring structure can always ensure that the monitoring probe 8 can contact with water while rotating to clean the monitoring probe 8, without affecting the monitoring process. In addition, preferably, the upper outer wall of the monitoring probe 8 can be connected to the center of the gear 72 through a small bearing, so that when the gear 72 rotates, it will not affect the monitoring probe 8, and the gear 72 can also rotate stably.

[0038] Preferably, the monitoring instrument body 9 includes a monitoring module for monitoring pH, dissolved oxygen and conductivity. A control cabinet 10 is fixed on the upper end of the monitoring instrument body 9. The control cabinet 10 includes a data transmission module. The monitoring module is unidirectionally connected to the data transmission module. The data transmission module includes GPS and WiFi. The data transmission module is unidirectionally connected to a remote terminal. The remote terminal includes a display screen and a remote control switch. Figure 5 As shown, the water pump 21, the monitoring instrument body 9 and the electromagnetic valve tube 11 are connected in parallel to a power supply, and the water pump 21, the monitoring instrument body 9 and the electromagnetic valve tube 11 are connected to a remote control switch, such as Figure 6 As shown, the pH value, dissolved oxygen and conductivity of water are monitored through the monitoring module of the monitoring instrument body 9.

The water quality monitoring data is transmitted to the remote terminal module through the GPS and WiFi of the data transmission module. The data is displayed on the display screen of the remote terminal module for personnel's reference. There is no need for personnel to go to the water environment of the Yangtze River Basin to take samples on site to monitor the water quality.

[0039] In addition, the present invention also discloses a monitoring method for the real-time monitoring device for the water environment in the Yangtze River Basin, which comprises the following steps:

[0040] S1: The water is pumped into the sampling box 1 through the water inlet pipe 22 by the water pump 21, and then discharged to the top of the sampling box 1 through the water outlet pipe 24. The water discharged through the water outlet pipe 24 falls on the filter screen 31, and flows into the sampling box 1 after being filtered by the filter screen 31;

[0041] S2: The water entering the sampling box 1 gradually contacts the monitoring probe 8 to monitor the water quality. At the same time, when the water in the sampling box 1 rises and gradually contacts the monitoring probe 8, the float 41 starts to rise in the sampling box 1, thereby pushing the lower end of the connecting rod 42 to move, so that the upper end of the connecting rod 42 pushes the filter screen 31 and the support rod 32 to rotate counterclockwise along the rotating shaft 33, and then gradually tilts and lifts. At this time, during the process of filtering water by the filter screen 31, a part of the water falling on the tilted filter screen 31 drives the impurities to flow and separate from the filter screen 31, and the other part of the water passes through the filter screen 31 and enters the sampling box 1;

[0042] S3: As the float 41 gradually rises and pushes the filter screen 31 to rotate counterclockwise, the float 41 rises and pulls the soft steel rope 54 upward, thereby pulling the chain 51 downward, causing the first sprocket 52 and the second sprocket 53 to rotate, thereby driving the disc 62 to rotate, driving the connecting column 74 to move back and forth, causing one end of the connecting column 74 to drive the rack 71 to slide back and forth in the slide rail 75, and finally driving the gear 72 to rotate back and forth, causing the cleaning brush 73 to rotate back and forth on the outer wall of the monitoring probe 8, thereby cleaning the monitoring probe 8;

[0043] S4: When the monitoring is completed, the remote control switch usually energizes the solenoid valve tube 11 to open and discharge the water in the sampling box 1.

[0044] Specifically, the overall working principle of this embodiment is as follows: the user starts the water pump and the main body of the monitoring instrument separately through the remote control switch, and the water is pumped into the water inlet pipe 22 by the water pump 21, and then discharged to the top of the sampling box 1 through the water outlet pipe 24. The water discharged through the water outlet pipe 24 falls on the filter screen 31, is filtered by the filter screen 31 and flows into the sampling box 1 to sample the water to be monitored. The water entering the sampling box 1 gradually contacts the monitoring probe 8. When the filtered water enters the sampling box 1 and rises and gradually contacts the monitoring probe 8, the float 41 begins to rise and float in the sampling box 1, pushing the lower end of the connecting rod 42 to move, so that the upper end of the connecting rod 42 pushes the filter screen 31 and the support rod 32 to rotate counterclockwise and gradually tilt and lift. At this time, during the process of filtering water by the filter screen 31, a part of the water falling on the inclined filter screen 31 drives the impurities to flow away from the filter screen 31, and the other part of the water passes through the filter screen 31 and enters the sampling box 1, thereby continuing to add water in the sampling box 1 During the process, the filter screen 31 is cleaned, so that water is continuously filtered into the sampling box and contacts with the monitoring probe 8 for water quality monitoring. In the process that the float 41 gradually rises and pushes the filter screen 31 to rotate counterclockwise, the float 41 rises and pulls the soft steel rope 54 upward, and pulls the chain 51 downward, so that the first sprocket 52 and the second sprocket 53 rotate, thereby driving the disc 62 to rotate, driving the connecting column 74 to move, so that the right end of the connecting column 74 drives the rack 71 to slide back and forth in the slide rail 75, driving the gear 72 to rotate back and forth, and making the three cleaning brushes 73 reciprocate on the outer walls of the three monitoring probes 8 respectively to clean the monitoring probe 8, which is conducive to the monitoring probe 8 contacting with the water in the sampling box 1 for monitoring. The cleaning brush 73 with a semi-circular ring structure ensures that the monitoring probe 8 can always be in contact with water while rotating to clean the monitoring probe 8, without affecting the real-time monitoring process. When the monitoring is completed, the remote control switch usually turns on the solenoid valve tube 11 to open and discharge the water in the sampling box 1.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.

At this time, during the process of filtering water by the filter screen (31), a part of the water falling on the tilted filter screen (31) drives the impurities to flow and leave the filter screen (31), and another part of the water passes through the filter screen (31) and enters the sampling box (1); S3: As the float (41) gradually rises and pushes the filter screen (31) to rotate counterclockwise, the float (41) rises and pulls the soft steel rope (54) upward, thereby pulling the chain (51) downward, causing the first sprocket (52) and the second sprocket (53) to rotate, thereby driving the disc (62) to rotate, driving the connecting column (74) to move back and forth, causing one end of the connecting column (74) to drive the rack (71) to slide back and forth in the slide rail (75), and finally driving the gear (72) to rotate back and forth, causing the cleaning brush (73) to rotate back and forth on the outer wall of the monitoring probe (8), thereby cleaning the monitoring probe (8); S4: When the monitoring is completed, the remote control switch is usually used to energize the solenoid valve tube (11) to open and discharge the water in the sampling box (1).
