Description

Technical Field

[0001] This application relates to the field of monitoring device technology, and in particular to an environmental monitoring device for surface water pollution prevention and control. Background Technology

[0002] Surface water refers to the total amount of dynamic and static water on the land surface, mainly including rivers, lakes, swamps, glaciers, ice caps, etc. It is one of the important sources of water for human life and a major component of water resources in various countries. In order to understand the water quality of surface water, it is necessary to monitor surface water regularly.

[0003] One type of monitoring device uses a telescopic float to monitor water levels, requiring a float to move with the liquid level gauge rod outside the gauge to take measurements.

[0004] When using the telescopic float method for measurement, since rivers and lakes are generally flowing water, the water flow impacts the float, causing it to move upwards, which makes accurate measurement impossible. Utility Model Content

[0005] To reduce the problem of inaccurate measurements caused by the movement of the float due to water impact, this application provides an environmental monitoring device for surface water pollution prevention and control.

[0006] This application provides an environmental monitoring device for surface water pollution prevention and control, which adopts the following technical solution:

[0007] An environmental monitoring device for surface water pollution prevention and control, comprising:

[0008] Suspension plate;

[0009] The monitoring component is fixed at the lower end of the suspension plate and is used to monitor the target water sample.

[0010] A support plate, the lower side of which is fixed to the upper end of the suspension plate;

[0011] The sampling component is located within the monitoring component and is used to collect the required water samples.

[0012] By adopting the above technical solution, the presence of the suspension plate allows the detection device to be placed on the water surface. The support plate increases the structural stability of the monitoring and sampling components. The presence of the sampling component allows the monitoring component to detect the target water sample without being affected by the external environment, thereby reducing the possibility of inaccurate measurements caused by the movement of the float due to water impact.

[0013] Optional, the monitoring components include:

[0014] The monitoring box is fixed at the upper end to the lower end of the suspension plate. The monitoring box has a receiving cavity, in which an opening is provided at the bottom.

[0015] The monitor is located inside the receiving cavity, and its upper end is fixed to the upper side wall of the receiving cavity.

[0016] The box has two lids, one end of which is connected to the two ends of the opening via a pivot.

[0017] By adopting the above technical solution, the presence of the rotating shaft allows the tank cover to be opened and closed, while the presence of the monitor is used to monitor the target water sample, increasing the structural stability of the monitoring tank.

[0018] Optionally, a spring is fixed to one end of the lid, with one end of the spring fixed to one side of the lid and the other end fixed to the lower side wall of the receiving cavity, for driving the lid to close.

[0019] By adopting the above technical solution, the presence of the spring ensures that when the lid is rotated up or down, the spring will close the lid due to its own elastic recovery, making it simple and easy to operate.

[0020] Optionally, the sampling components include:

[0021] The motor is fixed to the upper end of the support plate;

[0022] The telescopic rod passes through the support plate and the suspension plate and is installed inside the monitor. The fixed end of the telescopic rod is fixedly connected to the output shaft of the motor.

[0023] A sampler, one end of which is fixed to the output end of the telescopic rod;

[0024] A closure is fixed at the lower end of the sampler to secure the box lid.

[0025] By adopting the above technical solution, the motor drives the telescopic rod to rise and fall. At the same time, the telescopic rod drives the sampler to move up and down to take samples. When the sampler enters the monitoring box, the upper end of the closing part abuts against the lower end of the box cover, reducing the possibility of the box cover rotating downwards and increasing the connection stability of the two box covers.

[0026] Optional, the sampler includes:

[0027] The first conical barrel, the upper end of which is fixed to the telescopic end of the telescopic rod;

[0028] The second conical barrel has its upper end rotatably connected to the telescopic end of the telescopic rod.

[0029] The first conical barrel and the second conical barrel are provided with a first through hole at their upper ends, and the first conical barrel and the second conical barrel are provided with a second through hole at their circumferences.

[0030] By adopting the above technical solution, the first conical barrel and the second conical barrel are used together so that when the second conical barrel rotates, the water of the target water layer can enter the second conical barrel from the first through hole. When the sampler enters the detection box, the second conical barrel is rotated so that the collected target water sample flows into the monitoring box from the second through hole. It is simple and easy to operate.

[0031] Optional, the closure includes:

[0032] A connecting rod, one end of which is fixed to the lower end of the second conical barrel;

[0033] The closing plate has its upper end fixed to the other end of the connecting rod, and one end of the closing plate abuts against the lower end of the box cover to fix the two box covers.

[0034] By adopting the above technical solution, the presence of the closing plate prevents the box cover from rotating downwards, and the presence of the connecting rod drives the closing plate to move up and down simultaneously when the sampler moves up and down, thereby increasing the structural compactness of the closing plate and the sampler.

[0035] Optionally, a cleaning component is provided at the top of the monitoring box, including:

[0036] The connecting plate is rotatably connected to the upper side wall of the receiving cavity;

[0037] The cleaning plate has its upper end fixed to both ends of the connecting plate, and one side of the cleaning plate rotates and abuts against the receiving cavity.

[0038] By adopting the above technical solution, the presence of the cleaning plate and the connecting plate allows the connecting plate to rotate when the telescopic rod rotates. At the same time, the connecting plate drives the cleaning plate to rotate, thereby cleaning the side wall of the receiving cavity, reducing the contamination of the water sample by residues in the receiving cavity, and increasing the accuracy of monitoring.

[0039] Optionally, the receiving cavity is provided with a water outlet for water sample to flow out, wherein the cleaning plate opens and closes the water outlet.

[0040] By adopting the above technical solution, the presence of the water outlet allows the water sample inside the testing chamber to flow out, which is simple and convenient.

[0041] Optionally, an observation box is fixed on the support plate, and an indicator light is installed inside the observation box.

[0042] By adopting the above technical solution, the presence of the observation box and indicator lights facilitates the observation of water sample conditions. When the indicator light is on, it indicates an abnormality; when the indicator light is off, it indicates a normal condition.

[0043] Optionally, a solar panel is installed at the top of the observation box. The solar panel is electrically connected to the monitoring components to provide power to the monitoring components.

[0044] By adopting the above technical solution, the presence of solar panels provides power to the detection device, while also saving energy and being simple and convenient.

[0045] In summary, this utility model embodiment provides an environmental monitoring component for surface water pollution prevention and control, which includes at least one of the following beneficial technical effects:

[0046] 1. The presence of the suspension plate allows the detection device to be placed on the water surface. The support plate increases the structural stability of the monitoring and sampling components. The presence of the sampling component allows the monitoring component to detect the target water sample without being affected by the external environment, thereby reducing the possibility of the float moving due to water impact, which could lead to inaccurate measurements.

[0047] 2. The presence of the cleaning plate and the connecting plate allows the connecting plate to rotate when the telescopic rod rotates. At the same time, the connecting plate drives the cleaning plate to rotate, thereby cleaning the side wall of the receiving cavity, reducing the contamination of the water sample by residues in the receiving cavity, and increasing the accuracy of monitoring.

[0053] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0054] Combination Figure 1 and Figure 2 This application discloses an environmental monitoring device for surface water pollution prevention and control, including: a suspension plate 1, a monitoring component 2, a support plate 11, and a sampling component. The monitoring component 2 is fixed at the lower end of the suspension plate 1 and is used to monitor target water samples. The lower side of the support plate 11 is fixed at the upper end of the suspension plate 1. The sampling component is set inside the monitoring component 2 and is used to collect the required water samples.

[0055] In this embodiment, the suspension plate 1 is rectangular in shape. It should be noted that the specifications of the suspension plate 1 are larger than those of the monitoring component 2. That is, the length and width of the suspension plate 1 are both greater than those of the monitoring component 2. The material of the suspension plate 1 is a polypropylene plate. If necessary, the suspension plate 1 can also be made of foam or plastic. The support plate 11 is square in shape. The length and width of the support plate 11 are smaller than those of the suspension plate 1. In actual use, the support plate 11 is fixedly connected to the suspension plate 1. Then, the suspension plate 1 is placed in water, and the sampling component collects the target water sample. Then, the collected target water sample is poured into the monitoring component 2 for detection, thereby reducing the situation where the float moves due to the impact of water, which would lead to inaccurate measurement.

[0056] Combination Figure 2 In one specific embodiment, the monitoring component 2 includes a monitoring box 21, a monitor 22, and a box cover 23. The upper end of the monitoring box 21 is fixed to the lower end of the suspension plate 1. The monitoring box 21 has a receiving cavity 24, wherein the bottom of the receiving cavity 24 is provided with an opening 25. The monitor 22 is disposed in the receiving cavity 24, and the upper end of the monitor 22 is fixed to the upper side wall of the receiving cavity 24. Two box covers 23 are provided, and one end of the two box covers 23 is respectively connected to the two ends of the opening 25 through a rotating shaft 13. A spring 12 is fixed to one end of the box cover 23. One end of the spring 12 is fixed to one side of the box cover 23, and the other end is fixed to the lower side wall of the receiving cavity 24, which is used to drive the box cover 23 to close.

[0057] In this embodiment, both the monitoring box 21 and the monitor 22 are cylindrical. It should be noted that the diameter of the monitoring box 21 is larger than the diameter of the detector, and the length of the monitoring box is greater than the length of the monitor 22. The monitor 22 is a hollow cylinder, meaning it is annular and has a certain length. The length of the monitor 22 is set according to specific circumstances, and this embodiment does not impose a specific limitation. The receiving cavity 24 is cylindrical, and the opening 25 is square. It should be noted that the opening 25 is integrally formed at the lower end of the monitoring box 21, and the box cover 23 is square. It should be noted that the size of the two lids 23 is the same as the size of the opening 25. That is to say, the two lids 23 can close the opening 25. Both ends of the lids 23 are provided with guide arc surfaces to increase the rotation of the lids 23. The contact end of the two lids 23 is made of rubber to increase the tightness of the contact. If needed or desired, the contact end of the lids 23 can also be replaced with other materials with sealing properties. The rotating shaft 13 is cylindrical. The number of rotating shafts 13 corresponds one-to-one with the number of lids 23. That is to say, each lid 23 is provided with one rotating shaft 13.

[0058] In practical use, the sampling component is pushed downwards, causing the two box covers 23 to open due to the presence of the rotating shaft 13. At the same time, the spring 12 is stretched. When the sampling component is inserted into the water, the elastic recovery of the spring 12 closes the two box covers 23. When the sampling component moves upwards, it pulls the box covers 23 upwards. Due to the presence of the rotating shaft 13, the box covers 23 rotate upwards, compressing the spring 12. When the sampling component enters the monitoring box 21, the elastic recovery of the spring 12 causes the box covers 23 to rotate downwards, closing the opening 25, thus increasing the structural compactness of the monitor 22 and the sampling component.

[0059] Combination Figure 2 and Figure 3 In one specific embodiment, the sampling assembly includes a motor 31, a telescopic rod 32, a sampler 33, and a closure member 36. The motor 31 is fixed to the upper end of the support plate 11. The telescopic rod 32 passes through the support plate 11 and the suspension plate 1 and is disposed inside the monitor 22. The fixed end 321 of the telescopic rod 32 is fixedly connected to the output shaft of the motor 31. One end of the sampler 33 is fixed to the output end of the telescopic rod 32. The lower end of the sampler 33 is fixed with a closure member 36 for fixing the box cover 23.

[0060] In this embodiment, the telescopic rod 32 is conical in shape. It should be noted that the telescopic rod 32 includes a fixed end 321 and a telescopic end 322. The diameter of the fixed end 321 is larger than the diameter of the telescopic end 322. The sampler 33 is triangular in shape. It should be noted that the upper diameter of the sampler 33 is larger than the diameter of the telescopic end 322. The sampler 33 and the lower end of the telescopic end 322 can be integrally formed, or they can be fixed by welding or bolting. In actual use, the motor 31 is started, which drives the telescopic end 322 to extend downward, so that the telescopic end 322 drives the sampler 33 to extend into the target water layer and collect the target water sample. It is simple and easy to operate.

[0061] Combination Figure 3 Specifically, the sampler 33 includes a first conical barrel 331 and a second conical barrel 332. The upper end of the first conical barrel 331 is fixed to the telescopic end 322 of the telescopic rod 32. The upper end of the second conical barrel 332 is rotatably connected to the telescopic end 322 of the telescopic rod 32. The upper ends of the first conical barrel 331 and the second conical barrel 332 are provided with a first through hole 34 at intervals, and the periphery of the first conical barrel 331 and the second conical barrel 332 are provided with a second through hole 35 at intervals.

[0062] In this embodiment, both the first conical barrel 331 and the second conical barrel 332 are conical in shape. It should be noted that the first conical barrel 331 is larger than the second conical barrel 332; that is, the diameter and height of the second conical barrel 332 are greater than the diameter and height of the first conical barrel 331. Both the first through hole 34 and the second through hole 35 are circular. It should be noted that the diameters of the first through hole 34 and the second through hole 35 are determined by the specific application; that is, the diameters of the first through hole 34 and the second through hole 35 can be equal or unequal. In actual use, since the first conical barrel 331 is rotatably connected to the telescopic rod 32, rotating the telescopic rod 3... 2. This causes the second conical barrel 332 to rotate, while the first through hole 34 of the first conical barrel 331 and the second conical barrel 332 are connected. Then, after the target water sample enters the first conical barrel 331, the second conical barrel 332 is rotated, causing the first through hole 34 of the first conical barrel 331 and the second conical barrel 332 to be misaligned. That is, the second conical barrel 332 is closed. When the sampler 33 enters the monitoring box 21, the second conical barrel 332 is rotated, causing the second through hole 35 on the second conical barrel 332 and the first conical barrel 331 to be connected. The target water sample in the second conical barrel 332 flows into the monitoring box 21, and then monitoring is performed. This method is simple and easy to operate.

[0063] Combination Figure 2 and Figure 3Specifically, the closure 36 includes a connecting rod 361 and a closing plate 362. One end of the connecting rod 361 is fixed to the lower end of the second conical barrel 332; the upper end of the closing plate 362 is fixed to the other end of the connecting rod 361, and one end of the closing plate 362 abuts against the lower end of the box cover 23 to fix the two box covers 23.

[0064] In this embodiment, the connecting rod 361 is square-shaped. It should be noted that the thickness of the connecting rod 361 should not affect the closing of the lid 23, and there should be no water leakage when the lid 23 is closed. The closing plate 362 is circular. The closing plate 362 and the connecting rod 361 can be integrally formed, or they can be fixed by welding or bonding. This embodiment does not impose specific limitations. In actual use, when the telescopic rod 32 moves downward, the first conical barrel 331 moves downward. Simultaneously, the connecting rod 361 moves downward, and the first conical barrel 331 drives the two lids 23 to rotate downward, allowing the sampler 33 to penetrate deeper into the water layer to collect the target sample. When the telescopic rod 32 moves upward, the first conical barrel 331 moves upward, and the upper end of the first conical barrel 331 abuts against the lower end of the two box covers 23. As the first conical barrel 331 continues to move upward, due to the presence of the rotating shaft 13 and the spring 12, the first conical barrel 331 drives the two box covers 23 to rotate upward. When the first conical barrel 331 enters the monitoring box 21, the two box covers 23 close the opening 25. Then, the first conical rod continues to move upward, so that the upper end of the non-coating plate abuts against the lower side of the two box covers 23, reducing the possibility of the box covers 23 rotating downward and increasing the tightness of the closure of the two box covers 23.

[0065] Combination Figure 2 and Figure 3 More preferably, the upper end of the monitoring box 21 is provided with a cleaning component 4, which includes a connecting plate 41 and a cleaning plate 42. The connecting plate 41 is rotatably connected to the upper side wall of the receiving cavity 24. The upper end of the cleaning plate 42 is fixed to both ends of the connecting plate 41, and one side of the cleaning plate 42 rotatably abuts against the receiving cavity 24. The receiving cavity 24 is provided with a water outlet 43 for water sample to flow out, and the cleaning plate 42 opens and closes the water outlet 43.

[0066] In this embodiment, the connecting plate 41 is circular. It should be noted that the diameter of the connecting plate 41 is the same as the diameter of the receiving cavity 24, meaning the periphery of the connecting plate 41 abuts against the inner wall of the receiving cavity 24. The center of the receiving cavity 24 is rotatably connected to the fixed end 321 of the telescopic rod 32 via a gear 47. In other words, the fixed end 321 of the telescopic rod 32 is fixedly equipped with the gear 47. The connecting plate 41 is provided with a toothed groove 48 that meshes with the gear 47, allowing the gear 47 to embed within the toothed groove 48. The cleaning plate 42 is rectangular. It should be noted that the cleaning plate 42 has an arc, the arc of which is equal to the arc of the monitoring box 21. That is, one side of the cleaning plate 42 is attached to the inner wall of the receiving cavity 24, and the upper end of the cleaning plate 42 is fixedly connected to the connecting plate 41. The outlet 43 is circular and is located on the side wall of the receiving cavity 24, symmetrically arranged within it. The cleaning plate 42 can close the outlet 43. In actual use, when monitoring the target water sample, the cleaning plate 42 closes the outlet 43. After monitoring is completed, rotating the telescopic rod 32 causes the gear 47 to rotate, which in turn drives the connecting plate 41 to rotate. The connecting plate 41 drives the cleaning plate 42 to rotate. At the same time, the rotation of the cleaning plate 42 opens the outlet 43, allowing the target water sample to flow out. Then, the telescopic rod 32 is rotated again, causing the cleaning plate 42 to rotate against the side wall of the receiving cavity 24, cleaning the receiving cavity 24 and reducing the contamination of the target water sample by residues, thereby increasing the accuracy of the target water sample monitoring.

[0067] Combination Figure 2 and Figure 3 Even better, an observation box 44 is fixed on the support plate 11, and an indicator light 45 is installed inside the observation box 44; a solar panel 46 is installed at the upper end of the observation box 44, and the solar panel 46 is electrically connected to the monitoring component 2 to provide power to the monitoring component 2.

[0068] In this embodiment, the observation box 44 is square in shape. It should be noted that the observation box 44 is integrally formed on the support plate 11, and a placement cavity 26 is provided inside the observation box 44. The motor 31 is fixed to the bottom wall of the placement cavity 26. The observation box 44 is a transparent plate for easy observation. The solar panel 46 is rectangular in shape and is fixed to the top of the observation box 44. The indicator light 45 is cylindrical. It should be noted that the indicator light 45 is electrically connected to the monitor 22 and the solar panel 46. In actual use, the monitoring results of the monitor 22 are displayed through the indicator light 45. When an abnormality is detected, the indicator light 45 lights up. It should be noted that the solar panel 46 provides the power required for monitoring throughout the entire monitoring process, which is simple and convenient.

[0069] The implementation principle of this embodiment is as follows: The solar panel 46 provides the monitoring component 2 with the electrical energy required for monitoring. During specific monitoring, the motor 31 drives the free end of the telescopic rod 32 to move downward, allowing the sampling component to extend into the target water layer. The second conical barrel 332 is rotated, connecting the second conical barrel 332 with the first through hole 34 of the first conical barrel 331, thereby collecting the target water sample. Then, the free end of the rod is driven to move upward, causing the first conical barrel 331 to open the box cover 23, allowing the sampler 33 to enter the monitoring component 2. The telescopic rod 32 continues to move upward. 2. Make the lower end of the closing plate 362 abut against the lower end of the box cover 23 to reduce the downward rotation of the box cover 23. At the same time, pour the target water sample in the sampler 33 into the monitoring box 21. The monitor 22 monitors the sample. If the indicator light 45 is lit, it indicates an abnormality. If the indicator light 45 is not lit, it indicates normal operation. Then, rotate the telescopic rod 32 to open the water outlet 43 of the cleaning plate 42, allowing water to flow out of the monitoring box 21. At the same time, clean the inner wall of the receiving cavity 24 to reduce the movement of the float due to the impact of water, which could lead to inaccurate measurements.

[0070] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
