Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a monitoring system. Background Art

[0002] Surface water refers to the general term for dynamic and static water on the land surface, also known as "land water", including various liquid and solid water bodies, mainly rivers, lakes, swamps, glaciers, ice caps, etc. It is one of the important sources of water for human life. The quality of surface water is directly related to people's health, so it is necessary to monitor the quality of surface water (such as rivers).

[0003] When a water quality monitoring device is used to monitor the water quality of a river, it is necessary to place the monitoring probe into the water and bring it into contact with the water. When existing water quality monitoring devices are deployed in a monitoring area, a float is usually installed on the water quality monitoring device so that the water quality monitoring device floats on the water surface of the monitoring area. However, when the water level in the water quality monitoring area decreases, the floating height of the water quality monitoring device will also decrease as the water level decreases, making it easy for the monitoring probe of the water quality monitoring device to contact the bottom of the water or even sink into the mud, resulting in unstable monitoring data and inaccurate monitoring results. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defects of the water quality monitoring device in the prior art that the floating height decreases with the lowering of the water level, and the monitoring probe of the water quality monitoring device is easily in contact with the bottom of the water or even sinks into the mud, resulting in unstable monitoring data and inaccurate monitoring results, thereby providing a monitoring system.

[0037] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figures 1 to 3 The monitoring system provided in the present embodiment is shown, which is used for hydrological and water quality monitoring. Here, the monitoring system for hydrological and water quality monitoring of rivers is taken as an example. The monitoring system includes a support body 1 and a monitoring probe 2. The support body 1 is used to be installed in the water of the monitoring area of ​​the river, and the outer surface of the bottom of the support body 1 is suitable for being installed against the bottom of the water; the support body 1 is provided with an installation cavity 11 extending from the top of the support body 1 to the bottom of the support body 1, and a limiting portion is provided in the installation cavity 11. The side wall of the support body 1 is provided with a water supply channel 19 that connects the inside of the installation cavity 11 with the outside, so that water can enter the inside of the installation cavity 11 through the water supply channel 19, so that the monitoring probe 2 can perform hydrological and water quality monitoring; the monitoring probe 2 is movably arranged in the installation cavity 11 along the height direction, and the limiting portion is used to limit the monitoring probe 2 from descending to the lowest position, and the bottom surface of the monitoring probe 2 and the inner surface of the bottom of the installation cavity 11 are spaced in the height direction. It can be understood that the height direction of the present embodiment refers to Figure 1 when the monitoring probe 2 drops to the lowest position, the interval between the bottom surface of the monitoring probe 2 and the inner surface of the bottom of the mounting cavity 11 can be set as needed to ensure that the monitoring probe 2 does not touch the bottom and that the monitoring probe 2 can monitor data when the water level is low.

[0042] The monitoring system of the present embodiment is configured such that the monitoring probe 2 is movably arranged in the mounting cavity 11 of the supporting body 1 along the height direction, and the outer surface of the bottom of the supporting body 1 is suitable for contacting the bottom of the water. In the process of installing the monitoring system of the present embodiment in the water to be monitored in the monitoring area of ​​the river for hydrological and water quality monitoring, when the water level in the monitoring area of ​​the river drops, the bottom surface of the monitoring probe 2 always maintains a spacing with the lower end surface of the supporting body 1 along the height direction, and the outer surface of the bottom of the supporting body 1 can increase the contact area between the supporting body 1 and the bottom of the water, reduce the pressure, and reduce the depth of the supporting body 1 sinking into the bottom of the water (especially the silt), so that there is always a spacing between the monitoring probe 2 and the bottom of the water (especially the silt) along the height direction, ensuring that the monitoring probe 2 will not contact the bottom of the water and will not sink into the silt after the water level in the monitoring area of ​​the river drops to become a shallow water area, which is particularly convenient for arranging the monitoring probe 2 in a shallow water area with serious silt for water quality monitoring, thereby ensuring the stability of the water quality monitoring data obtained by the monitoring system of the present embodiment for monitoring the water in the monitoring area of ​​the river and the accuracy of the water quality monitoring results.

[0043] It should be noted that the monitoring system of the present application can also be used for monitoring in water in monitoring areas such as lakes and swamps that have similar technical difficulties.

[0044] like Figures 1 to 3 As shown, in some embodiments of the utility model, at least one ejector pin 12 is provided at the bottom of the support body 1, and is used to be inserted and fixed in the bottom mud at the installation position in the monitoring area of ​​the river. The ejector pin 12 is connected with the mud, so that the support body 1 is stably fixed at the installation position in the monitoring area of ​​the river, and the lower end surface of the support body 1 always abuts against the bottom of the water, ensuring that the bottom surface of the monitoring probe 2 always maintains a distance from the lower end surface of the support body 1 in the height direction as the water level drops, thereby ensuring that the monitoring probe 2 will never touch the bottom of the water and will not sink into the mud, thereby ensuring the accuracy and stability of the reading of the monitoring probe 2. It should be noted that the ejector pin 12 is arranged parallel to the height direction.

[0045] Specifically, the ejector pins 12 are provided in plurality, preferably six in number, and the six ejector pins 12 are arranged at intervals along the cross-sectional profile of the support body 1 perpendicular to the height direction. The six ejector pins 12 are inserted into the bottom of the water, so that the support body 1 is more stably fixed at the installation position in the monitoring area of ​​the river, and the lower end surface of the support body 1 always abuts against the bottom of the water.

[0046] In specific applications, the number of the ejector pins 12 can be reasonably increased or decreased according to the actual size of the support body 1. For example, in other embodiments, the number of the ejector pins 12 is two, three, four, five, seven, or other numbers.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, a connecting ear 13 is provided at the bottom of the support body 1, and a through hole 131 is formed on the connecting ear 13 along the height direction; the through hole 131 is used for a bolt to pass through and thread the counterweight. By connecting the counterweight, the center of gravity of the entire support body 1 is moved downward, which can ensure that the support body 1 is stably fixed at the installation position in the monitoring area of ​​the river, and the lower end surface of the support body 1 is always in contact with the bottom of the water; it can also prevent the support body 1 from being stolen. It is understandable that the counterweight can also be connected to the connecting ear 13 by tying the counterweight with a rope, and then passing the rope through the through hole 131 for hanging configuration.

[0048] Specifically, the connecting ears 13 are provided with a plurality of Figure 1 As shown, there are preferably six of them, and the six connecting ears 13 are arranged at intervals along the cross-sectional profile of the support body 1 perpendicular to the height direction. The six connecting ears 13 increase the number of counterweights to be installed, so that the support body 1 can be more stably fixed at the position to be installed in the monitoring area of ​​the river, and the lower end surface of the support body 1 always abuts against the bottom of the water. In order to allow more space on the support body 1 for the counterweight to be connected to the connecting ears 13, so as to ensure that the support body 1 is more stably fixed at the position to be installed in the monitoring area of ​​the river, the ejector pin 12 is connected to the outer surface of the bottom of the support body 1.

[0049] In specific applications, the number of the connecting ears 13 can be reasonably increased or decreased according to the actual size of the supporting body 1. For example, in other embodiments, the connecting ears 13 are provided with two, three, four, five, seven or other numbers.

[0050] In some embodiments of the utility model, a connecting ear 13 is provided at the bottom of the support body 1, and a through hole 131 is formed on the connecting ear 13 along the height direction; the through hole 131 is used for allowing the expansion bolt to pass through the bottom of the water at the installation position to be detachably connected in the monitoring area of ​​the river, which can ensure that the support body 1 is stably fixed in the monitoring area of ​​the river and the lower end surface of the support body 1 is always in contact with the bottom of the water; it can also prevent the support body 1 from being stolen.

[0051] like Figures 1 to 3As shown, in some embodiments of the utility model, the support body 1 includes a bottom plate 14 and a mounting frame 15, the bottom plate 14 forms the bottom of the support body 1, the bottom plate 14 and the mounting frame 15 are arranged at intervals along the height direction, and the bottom plate 14 and the mounting frame 15 are connected by a plurality of connecting rods 16, preferably six connecting rods 16, which are arranged at intervals along the outline of the mounting frame 15, and the space between two adjacent connecting rods 16 forms the water supply channel 19; the bottom plate 14, the mounting frame 15 and the connecting rods 16 surround the mounting cavity 11. By setting the bottom plate 14 to form the bottom of the support body 1, the mounting cavity 11 forms a non-through cavity structure, and the bottom plate 14 is used to increase the contact area with the silt. Under the premise of a certain pressure, the contact area is large and the pressure becomes small, so that the support body 1 is less likely to sink into the silt; and the structure of the support body 1 is simple, easy to manufacture and has a low manufacturing cost.

[0052] As another alternative to the above technical solution, the support body 1 includes a bottom plate 14 and a mounting frame 15, wherein the bottom plate 14 forms the bottom of the support body 1, and the bottom plate 14 and the mounting frame 15 are spaced apart in the height direction, and the bottom plate 14 and the mounting frame 15 are connected by a hollow net, preferably, the hollow net is arranged along the outer cross-sectional profile of the mounting frame 15 perpendicular to the height direction, and the mesh of the hollow net forms the water supply channel 19; the bottom plate 14, the mounting frame 15 and the hollow net enclose the mounting cavity 11. By replacing the six connecting rods 16 in the above technical solution with the hollow net, the mesh of the hollow net is smaller and denser, which can ensure that the water flows freely into the mounting cavity 11 and contacts the monitoring probe 2 for hydrological and water quality monitoring; and can also prevent the water plants and debris in the river from entering the mounting cavity 11 along with the water flow, thereby ensuring the accuracy of the measurement of the monitoring probe 2 and protecting the monitoring probe 2.

[0053] Specifically, the ejector pin 12 is connected to the outer surface of the bottom of the base plate 14; in order to facilitate the manufacture of the support body 1, more specifically, the connecting rod 16 and the corresponding ejector pin 12 are arranged on the same straight line in the height direction; more specifically, the connecting rod 16 and the ejector pin 12 are integrally arranged to form a whole, and the lower end of the connecting rod 16 in the height direction passes through the base plate 14 and extends downward to form the ejector pin 12; the connecting rod 16 is fixedly connected with the base plate 14 and the mounting frame 15 at the abutment thereof by welding.

[0054] In order to more effectively prevent the supporting body 1 from sinking into the mud, specifically, the cross-sectional shape of the bottom plate 14 perpendicular to the height direction is set to be circular.

[0055] In specific applications, the number of the connecting rods 16 can be reasonably increased or decreased according to the size of the outer cross-sectional dimensions of the support body 1 perpendicular to the height direction. For example, in other embodiments, the connecting rods 16 are provided in two, three, four, five, seven or other numbers.

[0056] like Figures 1 to 3 As shown, in some embodiments of the utility model, the installation frames 15 are provided in plurality, preferably two here, and the two installation frames 15 are arranged at intervals in the height direction, and the two installation frames 15 are connected by the connecting rod 16. By increasing the number of installation frames 15, the size of the support body 1 in the height direction is increased, that is, the size of the installation cavity 11 in the height direction is increased, so that the monitoring probe 2 can float and rise together without tilting during the rising water level in the monitoring area of ​​the river, and will not be separated from the installation cavity 11 and normally contact the water surface; ensure that the monitoring probe 2 will not contact the bottom of the water and will not sink into the mud after the water level in the monitoring area of ​​the river drops to a lower level to become a shallow water area.

[0057] In a specific application, the number of the installation frames 15 can be reasonably increased or decreased according to the height of the water level in the monitoring area of ​​the river. For example, in other embodiments, the installation frames 15 are provided with one, three, four or other numbers.

[0058] In order to further improve the overall structural strength of the support body 1, as Figure 1 and Figure 2 As shown, specifically, the inner diameter of the upper mounting frame 15 is smaller than the inner diameter of the lower mounting frame 15, the upper end surface of the connecting rod 16 is welded and fixed to the lower end surface of the upper mounting frame 15, and the middle side wall of the connecting rod 16 is welded and fixed to the inner wall of the lower mounting frame 15. More specifically, the outer side surface of the bottom plate 14 is sleeved with a fixing frame 18, and a gap 181 is provided between the inner wall of the fixing frame 18 and the outer wall of the bottom plate 14, and the gap 181 is provided for the lower end of the connecting rod 16 to pass through, and the lower end side wall of the connecting rod 16 is welded and fixed to the inner wall of the fixing frame 18 and the outer wall of the bottom plate 14. More specifically, the connecting ear 13 is provided on the outer side wall of the fixing frame 18. More specifically, two reinforcing rods 182 are disposed on the outer surface of the bottom of the base plate 14 . The two reinforcing rods 182 are arranged in a cross shape. Both ends of the reinforcing rods 182 along the length direction of the reinforcing rods 182 are respectively fixedly connected to the inner wall of the fixing frame 18 .

[0059] Specifically, a filter 17 is provided between the bottom plate 14 and the installation frame 15 closest to the bottom plate 14. When the support body 1 is arranged at the installation position in the monitoring area of ​​the river, the filter 17 is arranged on the water-facing surface. Considering that there are usually aquatic plants and debris on the bottom of the river, and they flow with the water flow, they enter the monitoring area of ​​the monitoring probe 2 of the installation cavity 11 from the water-facing surface between the bottom plate 14 and the installation frame 15 located at the bottom. The filter 17 can effectively intercept aquatic plants, debris, etc. from entering the monitoring area of ​​the monitoring probe 2, ensuring the accuracy of the measurement of the monitoring probe 2 and protecting the monitoring probe 2. In other embodiments, in order to better intercept aquatic plants, debris, etc. from entering the installation cavity 11, a filter 17 is also provided between the two installation frames 15.

[0060] like Figures 1 to 5 , Figure 7 As shown, in some embodiments of the utility model, a float 3 is fixedly connected to the upper end of the monitoring probe 2, and the float 3 is movably installed in the installation cavity 11 along the height direction, and when the monitoring probe 2 is lowered to the lowest position, the bottom of the float 3 abuts against the limit portion. In the process of rising water level in the monitoring area of ​​the river, the float 3 can provide sufficient buoyancy for the monitoring probe 2 to ensure that the monitoring probe 2 can float normally after the water level in the monitoring area of ​​the river rises to the high water level. The monitoring system of this embodiment can accurately perform hydrological and water quality monitoring in the monitoring area of ​​the river with high water level, and can also accurately perform hydrological and water quality monitoring in the monitoring area of ​​the river with low water level. Specifically, the fixed connection method of the monitoring probe 2 and the float 3 is not limited, for example, it can be fixedly connected to the mounting portion on the monitoring probe 2 through the mounting hole on the float 3.

[0061] It should be noted that when the water level in the monitoring area of ​​the river rises to the highest point, the float 3 floats on the water surface and does not completely break away from the installation cavity 11, ensuring that the float 3 descends in the height direction in the installation cavity 11 during the process of the water level in the monitoring area of ​​the river dropping again.

[0062] Specifically, the projection of the monitoring probe 2 on the horizontal plane is within the range of the projection of the float 3 on the horizontal plane; because the cross-sectional area of ​​the float 3 perpendicular to the height direction is larger than the cross-sectional area of ​​the monitoring probe 2 perpendicular to the height direction, on the one hand, it can ensure that sufficient buoyancy is provided for the monitoring probe 2, and on the other hand, the size of the float 3 along the height direction can be reduced on the basis of providing sufficient buoyancy for the monitoring probe 2, thereby reducing the space occupied by the installation cavity 11, so that the monitoring probe 2 has more room for movement along the height direction in the installation cavity 11. It can be understood that the horizontal plane described in this embodiment refers to a plane perpendicular to the height direction.

[0063] In some embodiments of the utility model, a limiter 151 is provided on the installation frame 15 closest to the bottom plate 14, and the installation frame 15 and the limiter 151 form the limiter. The limiter 151 can limit the lowest position of the float 3 in the height direction. When the float 3 drops along with the water level in the monitoring area of ​​the river to the position where the bottom of the float 3 abuts against the limiter 151, the limiter 151 limits the float 3 to ensure that the float 3 and the monitoring probe 2 cannot continue to drop along with the water level, ensuring that no matter how low the water level in the monitoring area of ​​the river drops, the bottom surface of the monitoring probe 2 is always spaced from the inner surface of the bottom of the installation cavity 11 in the height direction, thereby ensuring the accuracy and stability of the reading of the monitoring probe 2.

[0064] like Figure 1 and Figure 3 As shown, specifically, there are two limiters 151, and the space between the two limiters 151 is for the monitoring probe 2 to pass through in the height direction. The projections of the two limiters 151 on the horizontal plane are at least partially located within the range of the projections of the float 3 on the horizontal plane. The two limiters 151 can better limit the lowest position of the float 3 in the height direction. When the float 3 drops along with the water level in the monitoring area of ​​the river to the position where the bottom of the float 3 abuts the limiter 151, the limiter 151 limits the float 3 to ensure that the float 3 and the monitoring probe 2 cannot continue to drop along with the water level, ensuring that no matter how low the water level in the monitoring area of ​​the river drops to, the bottom surface of the monitoring probe 2 is always not in contact with the upper end surface of the bottom plate 14, thereby ensuring the accuracy and stability of the readings of the monitoring probe 2. More specifically, the two limiters 151 are arranged perpendicular to the height direction.

[0065] As another alternative to the above technical solution, a rope is provided inside the installation frame 15 closest to the base plate 14, and the installation frame 15 and the rope form the limiting portion; or the limiting portion is tied and hung at a set position in the installation cavity 11 by a rope, and the height to which the limiting portion descends is limited by the length of the rope.

[0066] It should be noted that when the water level in the monitoring area of ​​the river drops to the lowest level, the monitoring probe 2 is still in contact with the water surface.

[0067] like Figure 5 and Figure 7As shown, in some embodiments of the utility model, a photovoltaic panel 4 is provided at the upper end of the float 3, and the photovoltaic panel 4 is electrically connected to the monitoring probe 2 and used to supply power to the monitoring probe 2. The photovoltaic panel 4 absorbs and converts solar energy into electrical energy and provides it to the monitoring probe 2 for charging, which can save the circuit layout for connecting to the mains, so that the monitoring system of this embodiment can be arranged in a river in the wild for hydrological and water quality monitoring. At the same time, during the rising process of the water level in the monitoring area of ​​the river, the float 3 can provide sufficient buoyancy for the photovoltaic panel 4, ensuring that the photovoltaic panel 4 can float normally on the water surface after the water level in the monitoring area of ​​the river rises to the high water level, thereby ensuring that the monitoring probe 2 can be charged normally through the photovoltaic panel 4.

[0068] Specifically, the upper end surface of the float 3 is concavely provided with a mounting groove matching the photovoltaic panel 4. During assembly, the photovoltaic panel 4 is hidden and embedded in the mounting groove.

[0069] like Figures 4 to 6 As shown, in some embodiments of the utility model, an anti-smashing net 41 is arranged above the photovoltaic panel 4, and the projection of the photovoltaic panel 4 on the horizontal plane is located within the range of the projection of the anti-smashing net 41 on the horizontal plane. The anti-smashing net 41 covers the photovoltaic panel 4 for protection, effectively preventing the photovoltaic panel 4 from being damaged by debris, and extending the service life of the photovoltaic panel 4.

[0074] This embodiment does not limit the detachable connection structure between the mounting frame 42 and the photovoltaic panel 4, in order to further improve the convenience of disassembling and assembling the two on the basis of ensuring the connection stability between the mounting frame 42 and the photovoltaic panel 4; Figure 7 As shown, preferably, a plurality of threaded holes are arranged at intervals along the contour of the photovoltaic panel 4 perpendicular to the height direction on the end face of the photovoltaic panel 4 facing the mounting frame 42, preferably four threaded holes are provided here, and the mounting frame 42 is provided with through holes at positions corresponding to the threaded holes, and the through holes penetrate the mounting frame 42 along the height direction; when the mounting frame 42 and the photovoltaic panel 4 are assembled into one, the through holes are first aligned with the corresponding threaded holes, and then the fastening screws 44 are passed through the through holes and threadedly tightened in the threaded holes to complete the assembly of the mounting frame 42 and the photovoltaic panel 4; when the mounting frame 42 needs to be removed from the photovoltaic panel 4, it is only necessary to unscrew each fastening screw 44 from the corresponding threaded holes to complete the quick disassembly work, and the entire disassembly and assembly process is easy to operate.

[0075] Of course, the detachable connection structure between the mounting frame 42 and the photovoltaic panel 4 in the present application is not limited to the above-mentioned structure. As another replaceable embodiment of the above-mentioned technical solution, the mounting frame 42 is provided with a plurality of third through grooves arranged at intervals along the circumferential direction, preferably with four third through grooves, and the third through grooves penetrate the mounting frame 42 along the height direction; the upper end surface of the photovoltaic panel 4 is provided with fourth through grooves corresponding to the positions of the third through grooves; when the mounting frame 42 and the photovoltaic panel 4 are assembled into one, the third through groove and the fourth through groove are first aligned, and then the second mounting bolt is passed through the third through groove and the fourth through groove and the second nut is tightened to complete the assembly of the mounting frame 42 and the photovoltaic panel 4; when the mounting frame 42 needs to be removed from the photovoltaic panel 4, it is only necessary to unscrew each second mounting bolt from the corresponding second nut to complete the quick disassembly, and the entire disassembly and assembly process is easy to operate.

[0076] like Figures 4 to 7 As shown, in some embodiments of the present invention, a connecting ring 421 is provided at the outer edge of the upper end surface of the mounting frame 42, and the outer edge of the anti-smashing net 41 is detachably connected to the connecting ring 421 by a binding wire. By winding the binding wire, the anti-smashing net 41 is stably connected to the mounting frame 42 to form an integral body, and the binding wire can be rotated in the reverse direction to remove the binding wire, so that the damaged anti-smashing net 41 can be removed from the mounting frame 42 for repair or replacement.

[0077] In order to avoid the exposure of the binding wire, Figures 4 to 6As shown, specifically, the outer cover of the connecting ring 421 is provided with a protective edge 43, and the outer edge of the anti-smashing net 41 is arranged between the connecting ring 421 and the protective edge 43. It can be understood that the protective edge 43 is sleeved on the outside of the connecting ring 421 in an interference fit manner, and the friction between the protective edge 43 and the connecting ring 421 can ensure that the protective edge 43 and the connecting ring 421 are not separated when the monitoring system of this embodiment is used for normal water level and water quality monitoring, but a larger external force can be applied to separate the protective edge 43 from the connecting ring 421.

[0078] It should be noted that the above monitoring system can monitor hydrological water quality, such as turbidity, chemical oxygen demand, pH value, sediment content, etc. The above monitoring system also includes a monitoring device, which includes a shell, a spectral sensor and the monitoring probe 2. The space surrounded by the shell includes an external space and an internal space that are isolated from each other. The internal space is watertight, and the external space is for water samples to flow through. The internal space and the external space are arranged along the height direction. The detection end of the monitoring probe 2 is located in the external space, and the circuit part is located in the internal space. The spectral sensor includes an optical path adjustment element, which can adjust the optical path of the spectral sensor. Spectral sensors with different optical paths can detect the water quality of different water bodies, which further expands the scope of application of the water quality monitoring system, making it applicable to the monitoring of various water bodies, such as sewage pipe water, rainwater pipe water, surface water, etc. Based on the spectral sensor can monitor the COD, turbidity, sediment content, etc. of the obtained water sample, the above monitoring probe 2 can also include one or more of a pH probe, a dissolved oxygen probe, a conductivity probe, etc.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
