Description

Technical Field

[0001] The invention relates to a water environment monitoring device, in particular to a technology capable of monitoring different locations of a river. Background Art

[0002] Industrial wastewater refers to wastewater generated during the industrial production process, which usually contains a large amount of pollutants and harmful substances. Industrial wastewater is usually discharged into rivers after treatment.

[0003] In order to avoid pollution of river water environment, it is usually necessary to monitor the rivers. Monitoring is crucial to protecting water quality, maintaining ecological balance and ensuring the sustainable use of water resources.

[0004] The existing monitoring will monitor the water quality (such as pH value, dissolved oxygen, turbidity, etc.) through a monitoring head (sensor) and transmit the data to the central database. It should be noted that the existing monitoring equipment usually includes two types, one is direct detection monitoring, that is, some sensors are directly inserted into the water for real-time detection and data acquisition; the other is indirect detection, that is, sampling the river water environment and then testing it in a laboratory environment to achieve monitoring.

[0005] However, the existing sensor monitoring head is usually fixed, that is, the monitoring head is fixed at a certain position in the river and cannot be moved for monitoring; in addition, there are personnel who regularly move the monitoring device to the river position for sampling and monitoring. Such a process undoubtedly increases the workload and makes it difficult to achieve the purpose of real-time monitoring. Furthermore, the existing monitoring methods are usually limited to a single water surface height monitoring, while ignoring the monitoring of water at different depths. There is also no monitoring of underwater solids or semi-solid sludge, and this monitoring of different water depths and underwater sludge is also of great significance, because some pollutants that are not easily soluble in water need to be monitored from the underwater sludge part; in addition, some pollutants may be concentrated near the water surface (light pollutants) or concentrated in the underwater layer near the sludge side; however, the monitoring equipment in the prior art is also very inconvenient when monitoring different water layer heights and underwater sludge monitoring or sampling, especially it is difficult to complete the sampling process of multiple sites. Summary of the invention

[0006] In order to solve the problems existing in the above-mentioned technologies, the present invention provides a technology for monitoring different depths and sludge layers of a river or sampling sludge layers.

[0007] The present invention provides a water environment monitoring device, comprising a fixing rod, a monitoring component and a sampling member;

[0008] There are two fixing rods, an upper track and a lower track are respectively arranged between the two fixing rods, a movable trolley is arranged on the upper track, a liftable track structure is arranged on the upper track, a notch is arranged on the lower track, and the track structure cooperates with the notch;

[0009] The monitoring assembly is arranged at the front end of the trolley, and the monitoring assembly includes a lifting plate, a driving member and a monitoring head. The lifting plate is movably arranged in a vertical slot at the front end of the trolley, the driving member is used to drive the lifting plate to rise or fall, and the monitoring head is arranged at the lower side of the front end of the lifting plate;

[0010] The sampling piece is arranged at the lower end of the trolley.

[0011] The above beneficial effects are as follows: the bottom of the fixed rod is inserted into the river, the driving member drives the lifting plate to descend, and the monitoring head moves into the water. After that, the trolley moves on the upper track to drive the monitoring head to monitor different positions of the upper water surface. When the trolley moves to the track structure, the track structure descends and moves into the gap. The trolley can move on the lower track, and the monitoring head completes the monitoring of different positions of the lower water surface. When the upper track is located above the water and cannot be contacted to complete the monitoring, the lifting structure (the lifting plate, the driving member related structure) can be used to complete the monitoring of water samples at different depths during the lifting process. After the trolley moves to the track structure again, the track structure rises to the gap of the upper track, so that the monitoring head can complete the monitoring of two layers of different heights of the upper water surface and the lower water surface, and the water samples are monitored in real time at the upper position of the water and the underwater position close to the sludge, and the signal is transmitted to the control center. When the trolley is on the lower track, the sampling piece will enter the sludge, and it can be analyzed in real time whether it is necessary to temporarily increase the sampling and monitoring of the sludge. The sludge sampling work can be completed by the sampling piece.

[0012] Through this device, water at different depths can be monitored, and monitoring of multiple locations can also be achieved in the width direction. Furthermore, sampling can be carried out as needed when on the lower track, that is, the sampling can be completed by going deep into the sludge layer or the mud layer through the sampling piece for subsequent laboratory testing. In other words, in the case where rapid real-time testing cannot be completed through monitoring sensors, the subsequent testing process can be completed through sampling. It is very convenient to use, and can realize sampling processes in multiple lateral span directions, which is more accurate and convenient.

[0013] A preferred solution is that the lower end of the fixed rod is tapered, the trolley comprises an upper moving wheel, a lower moving wheel, a U-shaped block, two vertical plates, the upper moving wheel and the lower moving wheel are respectively movably arranged in grooves on the upper and lower sides of the upper track, two vertical plates are arranged at the outer ends of the two transverse plates of the U-shaped block, the upper moving wheel is arranged between the U-shaped block and the vertical plate at the upper end, the lower moving wheel is arranged between the U-shaped block and the vertical plate at the lower end, the driving member is a screw rod, the screw rod is arranged in the vertical groove, the vertical groove is arranged at the front end of the U-shaped block, and the lifting plate is arranged on the screw rod.

[0016] The working method of the water environment monitoring device provided by the present invention comprises the following steps: the bottom of the fixed rod is inserted into the river, and the height can be adjusted according to the depth of the river. The driving member drives the lifting plate to descend, and the monitoring head is moved into the water. Then, the trolley moves on the upper track to drive the monitoring head to monitor different positions of the upper water surface. When the trolley moves to the track structure, the track structure descends and moves into the gap. At this time, the trolley can move on the lower track, and the monitoring head completes the monitoring of different positions of the lower water surface. After the trolley moves to the track structure again, the track structure rises to the gap of the upper track. In this way, the monitoring head can complete the monitoring of two layers of different heights for the upper water surface and the lower water surface, and respectively perform real-time monitoring of water samples at the upper position of the water and the underwater position close to the sludge, and transmit the signal to the control center. When the trolley is on the lower track, the sampling piece will enter the sludge, and it can be analyzed in real time whether it is necessary to temporarily increase the sampling and monitoring of the sludge. Then, the sludge sampling work can be completed by the sampling piece.

[0017] The working method of the water environment monitoring device provided by the present invention comprises the following steps:

[0018] The motor drives the screw rod to rotate, causing the lifting plate to descend along the vertical groove.

Then, the electric drive causes the upper moving wheel and the lower moving wheel to move along the groove respectively, driving the U-shaped block and the monitoring head to move, so that the monitoring head can monitor different locations of the river.

[0026] First embodiment:

[0027] like Figures 1 to 3 As shown, a water environment monitoring device provided by the present invention includes a fixing rod 10, a monitoring assembly 30 and a sampling member 80;

[0028] There are two fixing rods 10, an upper track 20 and a lower track 50 are respectively arranged between the two fixing rods 10, a movable trolley 40 is arranged on the upper track 20, a liftable track structure 60 is arranged on the upper track 20, a notch 51 is arranged on the lower track 50, and the track structure 60 cooperates with the notch 51;

[0029] The monitoring assembly 30 is arranged at the front end of the trolley 40, and the monitoring assembly 30 includes a lifting plate 31, a driving member 310 and a monitoring head 32. The lifting plate 31 is movably arranged in a vertical slot 33 at the front end of the trolley 40, and the driving member 310 is used to drive the lifting plate 31 to rise or fall, and the monitoring head 32 is arranged at the lower side of the front end of the lifting plate 31;

[0030] The sampling member 80 is disposed at the lower end of the trolley 40;

[0031] The bottom of the fixed rod 10 is inserted into the river, and the insertion height can be adjusted according to the depth of the river. In general, the upper track and the lower track are located at different heights of the water, so that water samples of different depths can be monitored; in some cases, the upper track may be located above the water surface. In this case, the device can still monitor water of different depths through the lifting effect, and depth monitoring of multiple locations can be achieved. The driving member 310 drives the lifting plate 31 to descend, and the monitoring head 32 moves into the water. Then, the trolley 40 moves on the upper track 20 to drive the monitoring head 32 to monitor different positions of the upper water surface. When the trolley 40 moves to the track structure 60, the track structure 60 descends and moves into the gap 51. At this time, the trolley 40 can move on the lower track 50, and the monitoring head 32 completes the monitoring of different positions of the lower water surface. After the trolley 40 moves to the track structure 60 again, the track structure 60 rises to the gap 51 of the upper track 20. In this way, the monitoring head 32 can complete the monitoring of two layers of different heights for the upper water surface and the lower water surface, and perform real-time monitoring of water samples at the upper position of the water and the underwater position close to the sludge, and transmit the signal to the control center. When the trolley 40 is on the lower track 50, the sampling piece will enter the sludge, and it can be analyzed in real time whether it is necessary to temporarily increase the sampling and monitoring of the sludge. The sludge sampling work can be completed by the sampling piece. The sampling process is carried out according to the need, that is, when the monitoring sensor is unable to complete the monitoring of a certain indicator, the sampling process is completed to prepare for subsequent laboratory testing.

[0032] The monitoring sensor is, for example, an existing pH sensor, conductivity sensor, COD sensor, etc.

[0033] Second embodiment;

[0034] like Figure 2 and Figure 3As shown, the lower end of the fixed rod 10 is tapered, and the length of the tapered shape is preferably adjustable to adjust the insertion depth. The trolley 40 includes an upper moving wheel 41, a lower moving wheel 42, a U-shaped block 43, and two vertical plates 44. The upper moving wheel 41 and the lower moving wheel 42 are movably arranged in grooves 45 on the upper and lower sides of the upper track 20, respectively. Two vertical plates 44 are arranged at the outer ends of the two transverse plates 46 of the U-shaped block 43. The upper moving wheel 41 is arranged between the U-shaped block 43 and the vertical plate 44 at the upper end, and the lower moving wheel 42 is arranged between the U-shaped block 43 and the vertical plate 44 at the lower end. The driving member 310 is a screw rod 311, which is arranged in the vertical groove 33. The vertical groove 33 is arranged at the front end of the U-shaped block 43, and the lifting plate 31 is arranged on the screw rod 311.

[0035] The motor drives the screw rod 311 to rotate, so that the lifting plate 31 descends along the vertical groove 33, and the lifting plate 31 drives the monitoring head 32 to descend, so that the monitoring head 32 descends into the river for monitoring, and then the electric drive causes the upper moving wheel 41 and the lower moving wheel 42 to move along the groove 45 respectively, thereby driving the U-shaped block 43 and the monitoring head 32 to move, so that the monitoring head 32 can monitor different locations of the river.

[0036] Third embodiment;

[0037] like Figure 4 and Figure 5 As shown, a lower fixed frame 52 is provided on the rear side of the notch 51, an upper fixed frame 61 is provided on the rear side of the track structure 60, the rear end of the track structure 60 is connected to a lifting block 62, the middle part of the lifting block 62 is provided on a vertical screw rod 63, both sides of the lifting block 62 are respectively sleeved on a sliding rod 64, and the vertical screw rod 63 and the sliding rod 64 are respectively provided between the upper fixed frame 61 and the lower fixed frame 52.

[0038] When the trolley 40 drives the monitoring head 32 to move onto the track structure 60, the vertical screw rod 63 is driven to rotate by the rotating motor, so that the lifting block 62 descends along the slide rod 64, and the lifting block 62 drives the track structure 60 and the trolley 40 to descend to the position of the gap 51. Then the trolley 40 moves along the lower track 50, and the trolley 40 drives the monitoring head 32 to move, so that the monitoring head 32 monitors the underwater silt and soil at different locations. When the trolley 40 moves onto the track structure 60 again, the vertical screw rod 63 can be reversed, and the lifting block 62 drives the track structure 60 and the trolley 40 to rise, so that the track structure 60 moves to the gap position of the upper track 20, so that the upper side of the water can be monitored. Through the setting of the upper track 20 and the lower track 50, the monitoring head 32 can be monitored at different upper positions underwater or at different depths underwater near the silt, and can be switched as needed.

[0039] Fourth embodiment;

[0040] like Figure 2 As shown, the sampling member 80 includes a sampling tube 81, a closing plate 82 and a telescopic member 83. The sampling tube 81 is arranged at the lower side of the front end of the trolley 40, and the closing plate 82 is movably arranged in an insertion groove 84 on one side of the sampling tube 81. The telescopic member 83 drives the closing plate 82 to rise or fall.

[0041] When sampling is required at the corresponding position, the telescopic member 83 can be contracted to drive the closing plate 82 to move out of the insertion groove 84, so that the sampling tube 81 is opened. At this time, the water to be sampled will enter the sampling tube 81, and then the telescopic member 83 is extended, and the closing plate 82 is inserted into the insertion groove 84 to close the sampling tube 81. Then, the sampling tube 81 is moved to one end of the upper track 20 by the action of the trolley 40, and then, the water sample in the sampling tube 81 is discharged into the storage container through the suction pipe, the suction pump, and the discharge pipe by the action of the suction pump provided on the trolley 40.

[0042] The telescopic member is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod.

[0043] In other embodiments, when the trolley moves on the lower track, the sampling piece will enter into the sludge. At this time, a cylindrical container can be placed inside the sampling tube, and then the telescopic piece drives the closing plate to move up, the sampling tube is opened, and the sludge enters into the cylindrical container to complete the sampling of the sludge. Then the closing plate is driven down by the telescopic piece to complete the closure of the sampling tube. The trolley can then be switched to the upper track and moved to one end of the upper track. At this time, the closing plate is opened, and personnel can directly take the cylindrical container from the sampling tube for testing, and then a new cylindrical container can be placed in the sampling tube. When sampling water, a cylindrical container does not need to be placed, and it can be directly discharged from the sampling tube through the action of the suction pump.

[0044] In other embodiments, a filter screen is provided at the front end of the sampling tube, and through the filter screen, when water sampling is performed, impurities in the water can be filtered out of the sampling tube to avoid the presence of impurities in the sampled water. The sludge flows through the mesh of the filter screen into the cylindrical container.

[0045] When the sampling piece is sampling, if the silt cannot flow into the sampling barrel 81, or the flow is not smooth, the sampling barrel 81 can be made to move horizontally, that is, move along the lower track in the horizontal direction, and the silt can enter the sampling barrel 81 by scraping during the movement. That is, the lower track achieves a dual role, which can be used to realize water sample monitoring at multiple horizontal locations, and can also be used to scrape fixed samples of the silt layer of the sampling barrel. In addition, when the sampling barrel moves to one end of the upper track, it is very convenient to take the sample away, and the staff does not need to move into the water. In a further preferred embodiment, the bottom of the fixed rod is fixed in the river water by other fixing methods, which is more firmly fixed as needed.
