Description

Technical Field

[0001] The present invention relates to the technical field of sewage detection for environmental protection, and in particular to a sewage detection method for environmental protection. Background Art

[0002] Sewage is water that has deteriorated and can no longer maintain its original function due to the addition of new substances or changes in external conditions. From the perspective of the source of sewage, sewage can be defined as liquid or water containing waste that is mixed with groundwater, surface water, etc. and discharged from residential, institutional, commercial or industrial areas.

[0003] Wastewater testing and sampling is an important part of the daily work of environmental protection regulatory departments, mainly to ensure that the discharge of pollutants complies with environmental protection laws and standards.

[0004] In this context, the collection and testing of sewage has become an important part of environmental monitoring and management. Sampling sewage with a sampling device is one of the key steps in assessing water quality.

[0005] Sampling devices can accurately and reproducibly obtain water samples for chemical, biological, and physical analyses. These analyses not only help us understand the concentrations of different pollutants in water, but also assess their potential impacts on the environment and ecosystems.

[0006] Existing sampling methods usually require manual intervention. At this time, samples can only be taken at the edge of the sewage, and it is not easy to sample in the center of the sewage, which will reduce the persuasiveness of the sample data. In order to solve this problem, small boats are now used to transport the sampling device to the center of the sewage for sampling. However, since the surface of the contaminated sewage usually has garbage or algae floating on it, these things may block the sampling port during sampling, thereby affecting the sampling of the sampling device. Summary of the Invention

[0007] The purpose of the present invention is to provide a sewage detection method for environmental protection, which solves the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides a method for detecting wastewater for environmental protection, comprising the following steps:

[0010] The sampling water area is isolated by driving the multi-section electric push rod to move the baffle downward, isolating the sampling water area from the surrounding water area, preventing the sampling port from being blocked during the sampling process, making the sampling process smoother;

[0011] To deal with impurities in the sampling port, the baffle plate 1 moves downward while the two baffle plates 2 rotate with the rotating rod 1 as the axis with a delayed rotation, so as to push away the impurities around the sampling port, so that the impurities are further away from the sampling port. The two baffle plates 2 will not deflect until the baffle plate 1 has dropped a certain distance. By setting the delayed deflection, the baffle plate 1 can be used to prevent the backflow of impurities, further improving the effect of the sampling device in isolating impurities in the water.

[0012] For sample extraction, the multi-section electric push rod synchronously drives the piston piece to slide in the container with a delayed time, so as to draw the sewage sample into the container through the sampling tube.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0052] This embodiment provides a method for detecting wastewater for environmental protection, comprising the following steps:

[0053] The floating plate 1 is placed in the sewage and driven to the sewage sampling point by the propeller 4;

[0054] Drive the multi-section electric push rod 10 to drive the baffle 6 to move downward, isolating the sampling water area from the surrounding water area, preventing the sampling port from being blocked during the sampling process, making the sampling process smoother;

[0055] As baffle 1 6 moves downward, two baffles 2 32 rotate with a delayed rotation about rotating rod 1 30 to push away impurities around the sampling port, moving the impurities further away from the sampling port. Furthermore, after baffle 1 6 has descended a certain distance, two baffles 2 32 will deflect. By setting a delayed deflection, baffle 1 6 can be used to prevent the backflow of impurities, further improving the effectiveness of the sampling device in isolating impurities in water.

[0056] The multi-section electric push rod 10 synchronously drives the piston plate 18 to slide in the container 11 with a delayed time, so as to draw the sewage sample into the container 11 through the sampling tube 23. The sliding rod 14 slides in the sleeve 15, so that when the sample is extracted, the delayed sampling feature is also provided, that is, the water is pumped and sampled when the isolation component is pressed down and the component is pried apart. This further prevents the negative pressure caused by premature extraction at one end of the baffle 1 6 and the baffle 2 32, thereby affecting the normal flow of the liquid and further affecting the sampling effect of the random sampling of sewage, and further improves the persuasiveness of the sample data extracted by the sampling device;

[0057] The multi-section electric push rod 10 is driven to operate in the reverse direction, the position of the sliding frame 12 is restored, and the sewage sample is taken out again;

[0058] Then open the sewage detection box 35, take out the test paper in the sewage detection box 35, drop sewage on the test paper, and judge the degree of pollution of the sewage according to the degree of color change of the test paper. If it is found that the pollution is serious, send the sewage to the detection instrument in the laboratory to detect and obtain the accurate value of each element in the sewage.

[0059] Also, see Figures 2 to 9 This embodiment also provides a sewage detection device for environmental protection, wherein a baffle 16 is slidably connected to the side of a floating plate 1, and the upper end surface of the floating plate 1 is also fixedly connected to the control center 2, and a sewage detection box 35 is fixedly connected to the side of the control center 2, and the lower end surface of the sewage detection box 35 is fixedly connected to the upper end surface of the floating plate 1. A detection test paper is provided inside the sewage detection box 35, and a drive component is also provided on the surface of the control center 2, and the drive component includes:

[0060] A motor is provided inside the rotating shaft 3 and the control center 2. The end surface of the rotating shaft 3 is fixedly connected to the output end of the motor, and the end surface of the propeller 4 is fixedly connected to the end surface of the rotating shaft 3 away from the motor.

[0061] In this embodiment, the propeller 4 is provided to drive the float 1 of the device to move in the water, thereby driving the sampling device to move to the center of the sewage, making the sampling of the central sewage more convenient, thereby improving the persuasiveness of the sewage sampling sample data of the sampling device.

[0062] It is worth noting that in this embodiment, the sewage detection device further includes a downward pressure isolation component, which is disposed on the floating plate 1 and includes:

[0063] Connecting plate 29, the upper end surface of the floating plate 1 is provided with a sliding groove, the multi-section electric push rod 10 is fixedly connected to the groove wall of the sliding groove, the output end of the multi-section electric push rod 10 is fixedly connected to the end surface of the connecting plate 29, and the side surface of the connecting plate 29 is also slidably connected to the groove wall of the sliding groove. The end surface of the connecting plate 29 facing away from the multi-section electric push rod 10 is fixedly connected to a sliding frame 7, the outer side surface of the lower end of the sliding frame 7 is slidably connected to the groove wall of the sliding groove, and the inner wall of the sliding frame 7 is slidably connected to a sliding plate 8, and a through notch is provided on the side surface of the sliding plate 8, and the groove wall of the notch is fixedly connected to a toggle rod 9;

[0064] The triangle plate 25, the lower end surface of the triangle plate 25 is fixedly connected to the upper end surface of the floating plate 1, the end surface of the triangle plate 25 is slidably connected to the surface of the baffle 1 6, the inclined surface of the triangle plate 25 is fixedly connected to the sliding frame 1 24, the upper inner wall of the sliding frame 1 24 is slidably connected to the end surface of the toggle rod 9, and the end surface of the toggle rod 9 is also slidably connected to the sliding frame 2 26, and the lower outer surface of the sliding frame 26 is fixedly connected to the upper end surface of the baffle 1 6.

[0065] In this embodiment, by driving the multi-section electric push rod 10, the connecting plate 29 is driven to slide in the sliding groove, and further the sliding frame 1 7 is driven to move synchronously in the sliding groove. During the movement, the sliding plate 8 is driven to move, and the movement of the sliding plate 8 drives the toggle rod 9 to move, so that the toggle rod 9 slides in the sliding frame 1 24 and the sliding frame 2 26 at the same time. Since the sliding frame 1 24 is inclined, the sliding frame 1 24 can drive the sliding frame 2 26 to move downward during the movement, and then drive the baffle 1 6 to move downward, isolating the sampling water area from the surrounding water area;

[0066] The setting of this downward pressure isolation component isolates the sampling water area from the surrounding water area by driving the baffle 6 to move downward. When sampling sewage, the sewage will be sucked in to create negative pressure, thereby causing debris in the sewage to move toward the sampling port. When the debris is something that can block the sampling port, it will affect the smooth progress of the sampling process, further preventing the sampling port from being blocked during the sampling process, making the sampling process smoother. Example 2:

[0067] Based on the above examples, please refer to Figure 2 、 Figure 7 、 Figure 8 and Figure 9 In this embodiment, the sewage detection device further includes a prying assembly, which is also provided on the floating plate 1 and includes:

[0068] The mounting frame 5 has a side surface fixedly connected to the side surface of the floating plate 1. A through slot is formed on the end surface of the mounting frame 5. A rotating rod 30 is rotatably connected to the slot wall of the slot. A spring disk is fixedly connected to the end surface of the rotating rod 30. The end of the spring disk away from the rotating rod 30 is fixedly connected to the surface of the mounting frame 5. A mounting plate 31 is also fixedly connected to the surface of the mounting frame 5. A second baffle 32 is fixedly connected to the end surface of the mounting plate 31 away from the rotating rod 30.

[0069] Connecting plate 17, the end surface of connecting plate 17 is fixedly connected to the end surface of baffle 16 facing away from triangular plate 25, and the end surface of connecting plate 17 facing away from baffle 16 is also fixedly connected to residual straight tooth row 1 33;

[0070] The inner wall of the gear ring 1 34 is fixedly connected to the end surface of the rotating rod 1 30, and as the residual straight tooth row 1 33 moves downward, the tooth surface of the gear ring 1 34 is meshed and connected with the tooth surface of the residual straight tooth row 1 33.

[0071] In this embodiment, under the action of the spring disk, the baffle plate 2 32 can be kept in a horizontal state without being subjected to external forces. When the baffle plate 1 6 moves downward, it will simultaneously drive the connecting plate 17 to move downward. The downward movement of the connecting plate 17 will drive the residual straight tooth row 1 33 to move downward, so that the device has the following two motion states:

[0072] First, when the residual straight tooth row 1 33 moves downward, the plane of the residual straight tooth row 1 33 will first move to the gear ring 1 34. Since the plane of the residual straight tooth row 1 33 has no tooth surface, the downward movement of the residual straight tooth row 1 33 will not drive the gear ring 1 34 to rotate. Therefore, the baffle 2 32 will continue to remain in a horizontal state under the action of the spring disk.

[0073] Second, after the residual straight tooth row 1 33 continues to move downward, the tooth surface of the residual straight tooth row 1 33 will mesh with the tooth surface of the gear ring 1 34. At this time, the residual straight tooth row 1 33 continues to move downward, driving the gear ring 1 34 to rotate. The rotation of the gear ring 1 34 drives the rotating rod 1 30 to rotate. The rotation of the rotating rod 1 30 drives the mounting plate 1 31 to rotate. The rotation of the mounting plate 1 31 drives the baffle 2 32 to rotate, thereby removing the obstruction under the baffle 2 32.

[0074] The setting of the present prying assembly is to rotate the two baffles 32 around the rotating rod 1 30 as the axis, thereby prying away impurities around the sampling port, thereby reducing the possibility of the sampling port being blocked. Compared with the traditional direct isolation method, this method has a prying action, which can make the debris further away from the sampling port, and the effect of cleaning the debris is better. In addition, the two baffles 2 32 are set to delayed deflection, so that the two baffles 2 32 will not deflect until the baffle 1 6 drops a certain distance. When the two baffles 2 32 are pried, the water flow is disturbed. Through the setting of delayed deflection, the baffle 1 6 can be used to prevent the backflow of debris, further improving the effect of the present sampling device in isolating impurities in water. Example 3:

[0075] Based on the above examples, please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 In this embodiment, the sewage detection device further includes a water pumping sampling component, which is disposed on the floating plate 1 and includes:

[0076] Sliding block 1 27, the lower end surface of sliding frame 2 12 is slidably connected to the upper end surface of floating plate 1, the outer surface of sliding block 1 27 is slidably connected to the inner wall of sliding frame 2 12, the end surface of sliding block 1 27 facing sliding plate 8 is fixedly connected to connecting rod 1 28, and the end surface of connecting rod 1 28 away from sliding block 1 27 is fixedly connected to the side surface of sliding plate 8;

[0077] Connecting disk 13, the end surface of connecting disk 13 is fixedly connected to the outer surface of sliding frame 2 12, the end surface of connecting disk 13 facing away from sliding frame 2 12 is fixedly connected to sliding rod 14, the end surface of sliding rod 14 away from connecting disk 13 is fixedly connected to limiting disk 16, the surface of limiting disk 16 is slidably connected to sleeve 15, the inner wall of sleeve 15 away from the limiting disk 16 is provided with limiting block, piston plate 18 is fixedly connected to the outer end surface of sleeve 15 away from connecting disk 13, the inner wall of container 11 is slidably connected to the surface of piston plate 18, the outer surface of container 11 is fixedly connected to the upper end surface of floating plate 1;

[0078] One-way valve 22, the outlet end of one-way valve 22 is fixedly connected to the bottom side of container 11, the outer surface of sampling tube 23 is fixedly connected to the inlet end of one-way valve 22, and the end surface of sampling tube 23 away from one-way valve 22 also penetrates the upper end surface of floating plate 1;

[0079] One-way valve 21, the inlet end of one-way valve 21 is fixedly connected to the bottom side of container 11, the outlet end of one-way valve 21 is fixedly connected to fixed pipe 1 20, the end surface of fixed pipe 1 20 away from one end of one-way valve 21 is fixedly connected to the sampling container 19, and the outer surface of sampling container 19 is fixedly connected to the upper end surface of floating plate 1.

[0080] In this embodiment, the sliding plate 8 will simultaneously drive the connecting rod 1 28 to move during its movement, and the connecting rod 1 28 will drive the sliding block 1 27 to slide in the sliding frame 2 12, thereby driving the sliding frame 2 12 to move horizontally. During the horizontal movement of the sliding frame 2 12, the sliding rod 1 14 will first be driven to slide in the sleeve 15 through the connecting plate 13, thereby driving the limit plate 16 to move. When the sliding rod 14 moves a certain distance, the sliding rod 14 will no longer be able to slide in the sleeve 15, thereby driving the sleeve 15 to move, and the movement of the sleeve 15 will The piston plate 18 is driven to slide in the container 11, and then the sewage sample is drawn into the container 11 through the sampling tube 23 through the one-way flow of the one-way valve 12 and the one-way valve 21. After the sampling is completed, the position of the sliding frame 2 12 is restored under the action of the multi-section electric push rod 10. During the restoration process, the sliding rod 14 is also driven to slide in the sleeve 15. Finally, the liquid in the container 11 is pressed into the sampling container 19 for storage through the one-way flow of the piston plate 18 and the one-way flow of the one-way valve 22 and the one-way valve 21.

[0081] The arrangement of the present water pumping sampling device enables the sliding rod 14 to slide in the sleeve 15 so that when the present sampling device is in operation, the device also has the characteristic of delayed sampling. When the isolation component is pressed down and the component is pried open, water sampling is performed, which further prevents premature extraction from causing negative pressure at one end of the baffle 1 6 and the baffle 2 32, thereby affecting the normal flow of the liquid and further affecting the sampling effect of random sampling of sewage, and further improves the persuasiveness of the sample data taken out by the present sampling device.

[0082] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
