Description

Technical Field

[0001] The utility model relates to the field of sewage online samplers, in particular to a data drift correction system for sewage plant effluent online samplers. Background Art

[0002] With the rapid development of the economy, people's quality of life continues to improve, and sewage problems will directly affect people's living environment. When sewage treatment plants treat sewage, they need to use specific sewage sampling devices to sample sewage, and then use their specific detection systems to perform drift correction and detection on the collected water sample data, so as to adjust the sewage treatment plan according to the detection structure.

[0003] In the existing technology, when sampling sewage, most operators hold a support rod and put the sampling bottle at one end of the support rod into the water to fill it, and then take out the sampling bottle through the support rod. This sampling method makes it difficult to obtain water samples at different depths, reduces the diversity and comparability of sampling, and easily causes inaccurate detection quality, which is relatively inconvenient. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a data drift correction system for an online sampler of effluent from a sewage treatment plant, so as to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a data drift correction system for an online sampler of effluent from a sewage treatment plant, comprising a sampling cylinder, a support frame fixedly mounted on one end of the sampling cylinder, and a sealing gasket movably mounted inside the sampling cylinder, a sealing gasket movably mounted inside the sampling cylinder, and a movable plug threadedly connected to one end of the sampling cylinder, an air pipe fixedly mounted on one end of the sampling cylinder, a connecting rope fixedly mounted on one end of the support frame, and a sleeve sleeved on the outside of the connecting rope, a control rod fixedly mounted on one end of the sleeve, and a limiting plate fixedly mounted on one end of the control rod, an air pump connected to the air pipe fixedly mounted on one end of the limiting plate, and an auxiliary device for auxiliary sampling fixedly mounted on one end of the sealing gasket.

[0006] By adopting the above technical solution, by providing components such as a sampling cylinder, a filter plate, a connecting rope, a sealing gasket and a cover plate, when a worker uses this equipment to sample sewage, he only needs to rotate the rotating rod to control the position of the connecting rope and the sampling cylinder, and adjust the depth of the sampling cylinder inside the sewage according to the scale on its end face. After reaching the specified position, the vacuum pump is started to move the sealing gasket downward, thereby sampling the sewage. At the same time, during the sampling process, the filter plate can effectively filter the sewage. At the same time, after the sampling is completed, the cover plate will drive the sealing block to seal the sampling cylinder again, ensuring that when the worker drives the sampling cylinder to rise, the sewage will not enter the interior of the sampling cylinder again, thereby ensuring the accuracy of the sampling. Compared with traditional sewage sampling, this equipment can accurately adjust the position of the sampling cylinder inside the sewage according to requirements, and sample sewage at different depths. At the same time, the sampling process is more convenient and accurate, thereby improving its overall sampling efficiency and the accuracy of the test results.

[0007] The utility model is further configured as follows: the auxiliary equipment includes a connecting rod, a first movable rod, an extension block, a cover plate, a sealing block, a spring, a second movable rod and a movable groove; one end of the sealing gasket is fixedly mounted with the connecting rod, and one end of the connecting rod is fixedly mounted with the cover plate, one end of the cover plate is fixedly mounted with the sealing block, one end of the sampling cylinder is fixedly mounted with the extension block, and the first movable rod is movably mounted inside the extension block, and the extension block and the cover plate are connected by the first movable rod.

[0008] By adopting the above technical solution, the fixedly installed connecting rod allows the sealing gasket to move with the cover through the connecting rod. The sealing block will follow the movement of the cover and seal it again after contacting the sampling tube. The first movable rod cooperates with the extension block to effectively control the movement direction and distance of the cover, ensuring that it can seal the sampling tube normally and ensure the accuracy of sampling.

[0009] The utility model is further configured such that a second movable rod is movably installed inside the support frame, and a filter plate is fixedly installed on one end of the second movable rod, and a movable groove for the filter plate to move is opened inside the support frame.

[0010] By adopting the above technical solution, the movably installed second movable rod can drive the filter plate to move inside the support frame. The movable groove provides conditions for the filter plate to move inside the support frame, so that when it is squeezed by the sealing block, it will move toward the inside of the support frame to ensure the sealing effect.

[0011] The utility model is further configured such that the outer portion of the second movable rod is sleeved with a spring connected to the support frame and the filter plate, and the interior of the filter plate is provided with a first through hole for the connecting rod to move.

[0012] By adopting the above technical solution, the spring will continuously apply elastic force to the filter plate, so that it helps the filter plate to reset after it is no longer squeezed by the sealing block. The first through hole is for the connecting rod to pass through the filter plate normally, helping the sealing gasket to move and drive the cover plate to move normally.

[0013] The utility model is further configured such that a second through hole for the connection rope to pass through is opened inside the cover plate, a rotating rod is movably installed inside the limit plate, and the sampling tube and the rotating rod are connected by a connection rope.

[0014] By adopting the above technical solution, the second through hole provides space for the connecting rope to connect to the support frame, and the rotating rod and the sampling barrel are connected by the connecting rope, so that the worker can retract the connecting rope by turning the rotating rod to control the depth of the sampling barrel inside the sewage.

[0015] The present invention is further configured such that a counterweight is fixedly mounted on one end of the sampling tube, a handle is fixedly mounted on one end of the rotating rod, and a scale line is marked on the end face of the connecting rope.

[0016] By adopting the above technical solution, the counterweight block can be used to offset the buoyancy of water on the sampling tube, helping the sampling tube to better enter deeper into the sewage. The handle can facilitate workers to better control the rotation of the rotating rod to improve its winding efficiency. The scale line can help workers to more accurately determine the position of the sampling tube inside the sewage to ensure accurate sampling.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The utility model is provided with components such as a sampling cylinder, a filter plate, a connecting rope, a sealing gasket and a cover plate, so that when a worker uses the device to sample sewage, he only needs to rotate the rotating rod to control the position of the connecting rope and the sampling cylinder, and adjust the depth of the sampling cylinder inside the sewage according to the scale on its end face. After reaching the specified position, the vacuum pump is started to move the sealing gasket downward, thereby sampling the sewage. At the same time, during the sampling process, the filter plate can effectively filter the sewage. At the same time, after the sampling is completed, the cover plate will drive the sealing block to seal the sampling cylinder again, ensuring that when the worker drives the sampling cylinder to rise, the sewage will not enter the interior of the sampling cylinder again, thereby ensuring the accuracy of the sampling. Compared with traditional sewage sampling, the present device can accurately adjust the position of the sampling cylinder inside the sewage according to requirements, and sample sewage of different depths. At the same time, the sampling process is more convenient and accurate, thereby improving its overall sampling efficiency and the accuracy of the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] The following describes an embodiment of the present invention based on its overall structure.

[0027] A data drift correction system for online samplers of sewage treatment plant effluent, such as Figure 1-5As shown, it includes a sampling cylinder 1, one end of the sampling cylinder 1 is fixedly mounted with a support frame 2, and a sealing gasket 3 is movably mounted inside the sampling cylinder 1, a sealing gasket 3 is movably mounted inside the sampling cylinder 1, and one end of the sampling cylinder 1 is threadedly connected with a movable plug 11, one end of the sampling cylinder 1 is fixedly mounted with an air pipe 12, one end of the support frame 2 is fixedly mounted with a connecting rope 14, and the outer sleeve of the connecting rope 14 is provided with a sleeve 20, one end of the sleeve 20 is fixedly mounted with a control rod 19, and one end of the control rod 19 is fixedly mounted with a limit plate 21, one end of the limit plate 21 is fixedly mounted with an air pump 13 connected to the air pipe 12, and the sealing gasket 3 is fixedly mounted. An auxiliary device for auxiliary sampling is fixedly installed at one end. When using this equipment to sample sewage, workers only need to rotate the rotating rod 22 to control the position of the connecting rope 14 and the sampling tube 1, and determine the depth according to the scale on the end face of the connecting rope 14. When preparing for sampling, they only need to start the vacuum pump 13 so that it is affected by the piston effect, and the overall position of the sealing gasket 3 moves downward, driving the overall position of the cover plate 9 to move downward. As the sealing gasket 3 moves downward, the sewage will enter the interior of the sampling tube 1 through the filtration of the filter plate 4, and the sewage will be sampled. The sampling tube 1 is sealed again by the sealing block 10, and the sampled sewage will remain in the interior of the sampling tube 1.

[0028] See also Figure 1 - Figure 5 The auxiliary equipment includes a connecting rod 6, a first movable rod 7, an extension block 8, a cover plate 9, a sealing block 10, a spring 16, a second movable rod 17 and a movable groove 18. One end of the sealing gasket 3 is fixedly installed with a connecting rod 6, and one end of the connecting rod 6 is fixedly installed with a cover plate 9. One end of the cover plate 9 is fixedly installed with a sealing block 10. One end of the sampling tube 1 is fixedly installed with an extension block 8, and the first movable rod 7 is movably installed inside the extension block 8. The extension block 8 and the cover plate 9 are connected by the first movable rod 7. The fixed connecting rod 6 enables the sealing gasket 3 to move together with the cover plate 9 through the connecting rod 6 when it moves. The sealing block 10 will follow the movement of the cover plate 9 and seal it again after contacting the sampling tube 1. The first movable rod 7 cooperates with the extension block 8 to effectively control the moving direction and distance of the cover plate 9 to ensure that it can seal the sampling tube 1 normally and ensure the accuracy of sampling.

[0029] See also Figure 5 A second movable rod 17 is movably installed inside the support frame 2, and one end of the second movable rod 17 is fixedly installed with the filter plate 4. A movable groove 18 for the filter plate 4 to move is opened inside the support frame 2. The movably installed second movable rod 17 enables it to drive the filter plate 4 to move inside the support frame 2. The movable groove 18 provides conditions for the filter plate 4 to move inside the support frame 2, so that when it is squeezed by the sealing block 10, it will move toward the inside of the support frame 2 to ensure the sealing effect.

[0030] See also Figure 4 - Figure 5 The outside of the second movable rod 17 is provided with a spring 16 connected to the support frame 2 and the filter plate 4, and the inside of the filter plate 4 is provided with a first through hole 5 for the connection rod 6 to move. The spring 16 will continuously apply elastic force to the filter plate 4, so that it helps the filter plate 4 to reset after it is not squeezed by the sealing block 10. The first through hole 5 is for the connection rod 6 to pass through the filter plate 4 normally, which helps the cover plate 9 to move normally when the sealing gasket 3 moves.

[0031] See also Figure 1 - Figure 4 A second through hole 15 is provided inside the cover plate 9 for the connecting rope 14 to pass through. A rotating rod 22 is movably installed inside the limiting plate 21, and the sampling cylinder 1 and the rotating rod 22 are connected by the connecting rope 14. The second through hole 15 provides space for the connecting rope 14 to connect to the support frame 2. The rotating rod 22 is connected to the sampling cylinder 1 by the connecting rope 14, so that the worker can retract the connecting rope 14 by rotating the rotating rod 22, thereby controlling the depth of the sampling cylinder 1 inside the sewage.

[0032] See also Figure 1 - Figure 3 A counterweight 24 is fixedly installed at one end of the sampling tube 1, and a handle 23 is fixedly installed at one end of the rotating rod 22. The end face of the connecting rope 14 is marked with scale lines. The counterweight 24 can be used to offset the buoyancy of water on the sampling tube 1, helping the sampling tube 1 to better enter deeper into the sewage. The handle 23 can facilitate workers to better control the rotation of the rotating rod 22 and improve its winding efficiency. The scale lines can help workers to more accurately determine the position of the sampling tube 1 inside the sewage to ensure accurate sampling.

[0033] The working principle of the present invention is as follows: when using the device to sample sewage, workers only need to rotate the rotating rod 22 to control the position of the connecting rope 14 and the sampling tube 1. Under the restriction of the control rod 19 and the sleeve 20, the downward direction of the sampling tube 1 is ensured. After entering the sewage, the water inlet of the end face of the sampling tube 1 is blocked by the sealing gasket 3, so that the whole is in a sealed state. When the depth is determined according to the scale on the end face of the connecting rope 14 to prepare for sampling, it is only necessary to start the suction pump 13 so that it is affected by the piston effect, and the overall position of the sealing gasket 3 moves downward, driving the overall position of the cover plate 9 to move downward. As the sealing gasket 3 moves downward, the sewage will enter the interior of the sampling tube 1 through the filtration of the filter plate 4 to sample the sewage. As the sealing gasket 3 moves downward, the sealing block 10 at one end of the cover plate 9 will squeeze the filter plate 4 as a whole, causing the filter plate 4 to move downward. The sealing of the sampling tube 1 is completed again through the sealing block 10, and the sampled sewage is left inside the sampling tube 1. After turning off the air pump 13, the rotating rod 22 is rotated to control the sampling tube 1 to move upward. The worker turns the movable plug 11 to move the sealing gasket 3 to take out the sewage inside the sampling tube 1, and the sampling of the sewage is completed.

[0034] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
