Description

Technical Field

[0001] The utility model relates to the technical field of sewage detection, in particular to an industrial sewage detection device. Background Technique

[0002] Industrial sewage detection usually requires the use of various instruments and technologies, including spectrophotometers, ion chromatographs, pH meters, gas chromatographs, high-performance liquid chromatographs, atomic absorption spectrometers, etc. The detection results will be used to evaluate whether industrial emissions comply with relevant laws, regulations and environmental standards, and to guide factories to take appropriate treatment measures to protect the environment.

[0003] When detecting industrial sewage, it is usually necessary to sample the industrial sewage and detect the collected samples. However, currently when sampling industrial sewage, only the samples from the upper part of the water body are usually collected. However, the pollutants in industrial sewage are often unevenly distributed. Only collecting surface samples may not accurately reflect the overall water quality. There may be higher concentrations of wastewater and sediments at the bottom, and only collecting surface samples may cover up this situation. In addition, some pollutants may settle at the bottom of the water body due to their large weight. Therefore, surface sampling may not detect low-concentration pollutants, thus underestimating the actual pollution level. Therefore, only sampling the surface layer of industrial sewage may lead to misjudgment of the pollution level, pollution source and water quality status, and thus is not sufficient to accurately evaluate and monitor the quality and impact of industrial sewage. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an industrial sewage detection device, which solves the problem that only sampling the surface layer of industrial sewage may lead to misjudgment of the pollution level, pollution source and water quality status, and thus is not sufficient to accurately evaluate and monitor the quality and impact of industrial sewage.

[0005] To achieve the above object, the utility model provides the following technical solution: an industrial sewage detection device, including at least two connecting rods, a connecting frame and a sampling tank;

[0006] Two adjacent connecting rods are connected by threads. The connecting frame is sleeved outside the lowermost connecting rod. The sampling tank is installed inside the connecting frame, and the upper end of the sampling tank is open;

[0007] A driving rod is sleeved inside at least two connecting rods. Two adjacent driving rods are connected by threads. A sealing plug is assembled at the bottom end of the lowermost connecting rod to control the opening and closing of the opening of the sampling tank.

[0008] Further, the sealing plug is a rubber plug, and the center point of the sampling tank and the center point of the sealing plug are on the same vertical line.

[0009] Further, the plug is in interference fit inside the opening of the sampling tank.

[0010] Further, a spring is assembled between the inner top wall of the plug and the connecting frame.

[0011] Further, the spring is sleeved outside the driving rod.

[0012] Further, a discharge pipe is communicated with the bottom of the sampling tank, and a sealing cover is threadedly connected to the outside of the discharge pipe.

[0013] Further, a spherical handle is threadedly connected to the top end of the driving rod.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] For this industrial sewage detection device, by inserting the plug into the opening of the sampling tank, then holding the connecting rod and inserting the sampling tank into the sewage, the depth of the sampling tank in the sewage is determined according to requirements. Then, the driving rod is pulled upward, and the driving rod pulls out the plug from the opening inside the sampling tank. At this time, the sewage can enter the sampling tank from the opening of the sampling tank. Finally, the driving rod is pushed downward to push the plug into the opening inside the sampling tank again to seal the sampling tank. At this time, the collection of sewage at this depth can be realized, thereby improving the accuracy of the sewage detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , an industrial sewage detection device in this embodiment is used to collect sewage at different depths to detect the values of sewage at different depths and improve the accuracy of sewage detection results.

[0023] Specifically, it includes at least two connecting rods 1, a connecting frame 2 and a sampling tank 3; adjacent two connecting rods 1 are connected by threads, the connecting frame 2 is sleeved outside the lowermost connecting rod 1, the sampling tank 3 is installed inside the connecting frame 2, and the upper end of the sampling tank 3 is open; a driving rod 4 is sleeved inside at least two connecting rods 1, adjacent two driving rods 4 are connected by threads, and a sealing plug 5 is assembled at the bottom end of the lowermost connecting rod 1 to control the opening and closing of the opening of the sampling tank 3.

[0024] During the actual use process, the length of the connecting rod 1 is determined according to the depth of the sewage, that is, by connecting two connecting rods 1 with threads, the length of the connecting rod 1 can be increased or decreased to adapt to the collection of sewage at different depths.

[0025] When collecting sewage, first insert the sealing plug 5 into the opening of the sampling tank 3, then hold the connecting rod 1 and insert the sampling tank 3 into the sewage. Determine the depth of the sampling tank 3 inside the sewage as required, and then pull up the driving rod 4. The driving rod 4 pulls out the sealing plug 5 from the opening inside the sampling tank 3. At this time, the sewage can enter the sampling tank 3 from the opening of the sampling tank 3. Finally, push down the driving rod 4 to push the sealing plug 5 into the opening inside the sampling tank 3 again to close the sampling tank 3. At this time, the collection of sewage at this depth can be realized, thereby improving the accuracy of the sewage detection results.

[0026] Furthermore, in order to ensure that the sealing plug 5 can effectively close the sampling tank 3 and at the same time ensure that the sealing plug 5 can effectively close the sampling tank 3, the sealing plug 5 in this embodiment is a rubber plug. The center point of the sampling tank 3 and the center point of the sealing plug 5 are located on the same vertical line, and the sealing plug 5 is in interference fit inside the opening of the sampling tank 3.

[0027] In actual setting, through the interference fit between the plug 5 and the sampling tank 3, it is ensured that the plug 5 can effectively close the sampling tank 3 to prevent sewage at other levels from entering the interior of the sampling tank 3. Moreover, by ensuring that the centers of the plug 5 and the sampling tank 3 are aligned, the position of the plug 5 is ensured to be correct, avoiding poor sealing or operation difficulties caused by deviation.

[0028] Furthermore, to increase the convenience of closing the sampling tank 3, in this embodiment, a spring 6 is assembled between the plug 5 and the inner top wall of the connecting frame 2, and the spring 6 is sleeved outside the driving rod 4.

[0029] During the actual use process, by pulling up the driving rod 4, the plug 5 can be driven to move upward. At the same time, the spring 6 is compressed. At this time, the spring 6 gives the plug 5 a downward elastic potential energy, ensuring that after the driving rod 4 is released, the plug 5 can automatically move to the opening of the sampling tank 3. At this time, only by pressing down the driving rod 4, the entire plug 5 can be inserted into the opening of the sampling tank 3.

[0030] It should be noted that, to facilitate the up and down movement of the driving rod 4, a spherical handle 9 is threadedly connected to the top end of the driving rod 4 in this embodiment.

[0031] In addition, to facilitate the removal of the sewage collected in the sampling tank 3, a discharge pipe 7 is connected to the bottom of the sampling tank 3, and a sealing cap 8 is threadedly connected to the outside of the discharge pipe 7.

[0032] During the actual use process, by unscrewing the sealing cap 8 from the outside of the discharge pipe 7, the sewage can be discharged from the interior of the sampling tank 3 at this time, increasing the convenience of sewage detection.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
