Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling equipment, in particular to a sampling device for municipal sewage treatment. Background Art

[0002] Municipal sewage treatment refers to the treatment of urban domestic sewage to reduce or eliminate pollutants in it and protect the environment and human health. The domestic sewage generated in the city is collected through the sewer system. The collected domestic sewage is pre-treated, including the removal of large particles, sand, soil and other impurities. Through different treatment processes, such as biological treatment, physical treatment, chemical treatment, etc., organic matter, inorganic matter, nutrients and other pollutants in the sewage are removed. The treated water is disinfected to kill residual bacteria and pathogens. Municipal sewage needs to regularly test the sewage in the pipeline. By testing various pollutants in the sewage, the impact of sewage on the surrounding environment can be evaluated. Harmful microorganisms, heavy metals, organic matter and other components that are harmful to human health may exist in the sewage. Through testing, it can be ensured that the treated sewage meets the safe discharge standards and protects public health.

[0003] Most of the existing sewage testing is done by pumping out sewage from pipes through water pump sampling equipment, which is then packaged and stored to assist in testing. However, water pump sampling equipment is not only expensive to use, but also requires constant movement of the equipment when testing at multiple points, which is not only time-consuming and labor-intensive but also prone to bumps and other problems during transportation.

[0004] In view of this, we propose a sampling device for municipal sewage treatment. Utility Model Content

[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part 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 creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 2 As shown, a sampling device for municipal sewage treatment in an embodiment of the first aspect of the utility model comprises a circular plate 11, the surface of the circular plate 11 is evenly rotatably connected to a support rod 13, the other end of the support rod 13 is rotatably connected to a support 14, a circular opening is provided at the center of the surface of the circular plate 11, a conduit 15 is fixedly installed at the bottom of the circular opening of the circular plate 11, and a collection bucket 31 is also included, a lifting assembly is provided on the surface of the circular plate 11, the lifting assembly can lift the collection bucket 31 to assist in sewage sampling in the municipal pipeline, a collar 16 is slidably connected to the surface of the collar 16, a connecting rod 17 is evenly rotatably connected to the surface of the collar 16, and the other end of the connecting rod 17 is rotatably connected to the surface of the support rod 13;

[0024] In the above embodiment, it should be noted that there are three support rods 13, and the support rods 13 can rotate on the outside of the circular plate 11. When the support rods 13 rotate, they can drive the connecting rods 17 to rotate. When the ring 16 reaches the bottom, the support rods 13 are at the maximum support angle. At this time, the support rods 13 can be placed on the top of the municipal pipeline. At this time, the collection bucket 31 can enter the municipal pipeline with the assistance of the lifting assembly.

[0025] Example 2

[0026] like Figure 3-Figure 4 As shown, a sampling device for municipal sewage treatment in an embodiment of the first aspect of the utility model includes all the contents of embodiment 1. In addition, the lifting assembly includes a fixed seat 21, and the fixed seat 21 is fixedly installed on one side of the surface of the conduit 15. A winding drum 22 is provided on one side of the fixed seat 21, and one side of the winding drum 22 is fixed to the fixed seat 21 through a rotating shaft. A rope 25 is wound around the surface of the winding drum 22, and a shell 23 is provided on one side of the winding drum 22. The other side of the winding drum 22 is rotatably connected to the shell 23 through a metal rod. A first gear 231 is fixedly mounted on one end of the metal rod of the winding drum 22, and a second gear 232 is rotatably connected to the other side of the inner wall of the housing 23. The second gear 232 is meshed with the first gear 231, and a handle 233 is fixedly mounted on one side surface of the second gear 232. The lifting assembly also includes a wire seat 24, and rollers are rotatably connected to both sides of the inner wall of the wire seat 24. The rope 25 passes through the roller surface of the inner wall of the wire seat 24, and one end of the rope 25 passes through the circular opening of the circular plate 11 and extends to the other side of the inner wall of the catheter 15.

[0027] In the above embodiment, it should be noted that the winding drum 22 can rotate on one side of the shell 23. When the winding drum 22 rotates, it can drive the first gear 231 to rotate. Since the first gear 231 is engaged with the second gear 232, when the handle 233 is rotated, it can drive the winding drum 22 to rotate, thereby retracting and releasing the rope 25 wound on the surface. The rope 25 can be assisted in releasing the wire by the rollers arranged on the inner wall of the wire holder 24, thereby reducing the friction of the rope 25 on the inner wall of the catheter 15.

[0028] Example 3

[0029] like Figure 3-Figure 4 As shown, a sampling device for municipal sewage treatment in the embodiment of the first aspect of the utility model includes all the contents of embodiment 2. In addition, the collection bucket 31 is a barrel structure with an open top, and the outer wall of the opening of the collection bucket 31 is evenly provided with threads. A cover plate 32 is provided on the top of the collection bucket 31, and the cover plate 32 is threadedly connected to the collection bucket 31. A water inlet is evenly opened on the surface of the cover plate 32, and a filter is fixedly installed on the inner wall of the water inlet of the cover plate 32. A lifting ring 33 is evenly fixedly installed on the top surface of the cover plate 32, and the lifting ring 33 can be connected to the rope 25;

[0030] In the above embodiment, it should be noted that one end of the rope 25 can be connected to the ring 33 on the top surface of the cover plate 32, and the number of the rings 33 is three, which can keep the cover plate 32 stable after the rope 25 is connected to the cover plate 32. After the collection bucket 31 is connected to the cover plate 32, the sewage can be collected through the water inlet opened on the surface of the cover plate 32 and the impurities in the sewage can be filtered through the filter.

[0031] The use process of the utility model is as follows. A person skilled in the art will manually unfold the support rod 13, place it on the top of the municipal pipe, connect one end of the rope 25 to the ring 33 on the top surface of the cover plate 32, and then connect the collection bucket 31 to the cover plate 32. At this time, rotating the handle 233 can drive the winding drum 22 to rotate, so as to lower the rope 25 wound on the surface. The rope 25 can be assisted in releasing the line by the roller arranged on the inner wall of the wire seat 24, thereby reducing the friction of the rope 25 on the inner wall of the conduit 15, and collecting the sewage through the water inlet opened on the surface of the cover plate 32 and filtering the impurities in the sewage through the filter screen.

[0032] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
