Description

Technical Field

[0001] The 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 carrying waste that is mixed with groundwater, surface water, etc. and discharged from residential, institutional, commercial or industrial areas.

[0003] Sewage 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 using 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 analysis. These analysis results not only help to understand the concentration of different pollutants in water bodies, but also to assess their potential impact on the environment and ecosystems.

[0006] Existing sampling methods usually require human intervention. When sampling, samples can only be taken at the edge of the sewage. 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 there is usually garbage or algae floating on the surface of the contaminated sewage, these things may block the sampling port during sampling, thereby affecting the sampling of the sampling device.

[0021] In this embodiment, the propeller 4 can be used to drive the floating plate 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.

[0022] It is worth noting that, in this embodiment, the sewage detection device further includes a downward pressure isolation component, which is arranged on the floating plate 1 and includes: The connecting plate 29 and the upper end surface of the floating plate 1 are 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 away from the multi-section electric push rod 10 is fixedly connected to a sliding frame 7, the lower end outer side surface of the sliding frame 7 is slidably connected to the groove wall of the sliding groove, the inner wall of the sliding frame 7 is slidably connected to a sliding plate 8, the side surface of the sliding plate 8 is provided with a through notch, and the groove wall of the notch is fixedly connected to a toggle rod 9; Triangle plate 25, the lower end surface of triangle plate 25 is fixedly connected to the upper end surface of floating plate 1, the end surface of triangle plate 25 is slidably connected to the surface of baffle 1 6, the inclined surface of triangle plate 25 is fixedly connected to sliding frame 1 24, the upper inner wall of sliding frame 1 24 is slidably connected to the end surface of toggle rod 9, the end surface of toggle rod 9 is also slidably connected to sliding frame 2 26, the lower outer surface of sliding frame 26 is fixedly connected to the upper end surface of baffle 1 6.

[0023] In this embodiment, the connecting plate 29 is driven to slide in the sliding groove by driving the multi-section electric push rod 10, and the sliding frame 7 is further 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.

When sampling sewage, the sewage will be sucked 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. Embodiment 2:

[0024] Based on the above examples, please refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the sewage detection device further includes a prying assembly, which is also disposed on the floating plate 1 and includes: The mounting frame 5, the side of the mounting frame 5 is fixedly connected to the side of the floating plate 1, the end surface of the mounting frame 5 is provided with a through slot, the rotating rod 1 30 is rotatably connected to the slot wall of the slot, the end surface of the rotating rod 1 30 is fixedly connected with a spring disk, the end of the spring disk away from the rotating rod 1 30 is fixedly connected to the surface of the mounting frame 5, the surface of the mounting frame 5 is also fixedly connected with a mounting plate 1 31, and the baffle 2 32 is fixedly connected to the end surface of the mounting plate 1 31 away from the rotating rod 1 30; A connecting plate 17, the end surface of the connecting plate 17 is fixedly connected to the end surface of the baffle 16 away from the triangular plate 25, and the end surface of the connecting plate 17 away from the baffle 16 is also fixedly connected to a residual straight tooth row 33; The gear ring 34 has an inner wall that is fixedly connected to the end surface of the rotating rod 30, and as the residual straight tooth row 33 moves downward, the tooth surface of the gear ring 34 is meshed and connected with the tooth surface of the residual straight tooth row 33.

[0025] 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 force. When the baffle plate 1 6 moves downward, the connecting plate 17 will be driven to move downward at the same time. 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: 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 there is no tooth surface on the plane of the residual straight tooth row 1 33, the downward movement of the residual straight tooth row 1 33 will not drive the gear ring 1 34 to rotate, so that the baffle 2 32 will continue to remain in a horizontal state under the action of the spring disk; 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 to drive the gear ring 1 34 to rotate, and the rotation of the gear ring 1 34 drives the rotation rod 1 30 to rotate, and the rotation of the rotation rod 1 30 drives the installation plate 1 31 to rotate, and the rotation of the installation plate 1 31 drives the baffle plate 2 32 to rotate, thereby removing the obstruction under the baffle plate 2 32; The setting of the prying component is to rotate the two baffles 2 32 around the rotating rod 1 30 as the axis, thereby pushing away the 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 pushing action, which can make the debris farther away from the sampling port, and the effect of cleaning the debris is better. 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. The two baffles 2 32 will disturb the water flow when they are pushed. 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 sampling device in isolating impurities in the water.
