Further, because the total flow of the water outlets 24 is less than the total flow of the water inlets 26, in this embodiment, a plurality of overflow water outlets 25 are further formed on the sidewall of the bottle 14, and the overflow water outlets 25 are disposed above the sampling suction pipe 13, so that the design has the advantages that: can ensure that the sampling suction pipe 13 is always in a water immersion state, and ensure the smoothness of water pumping and sampling. The bottle body 14 is secured to the peripheral fixable region by a fixing clip 23 provided and then by the fixing rod 15 in this embodiment in order to prevent the bottle body from being hit by other foreign objects such as a mouse.

A sewage sampling system using the sewage sampling bottle as described above, as shown in fig. 1 to 9, includes a height drop zone; the upper rear side of the height falling zone is communicated with an upstream pipeline 1, and the lower front side of the height falling zone is communicated with a downstream pipeline 5; the step section 9 of the height drop zone is designed to be an inward concave surface or an inward inclined surface, that is, for example, the inward inclined surface is the structure shown in fig. 1, and the lower part of the step section 9 is inclined inward, so that the design aims to: as shown in fig. 3, after the drop height section 9 is set to be inclined, a main flow area, namely an M area, serving as a main flow area of sewage, and a safety area, namely an S area, are formed, wherein main sewage, large wastes and the like flow in the M area, and particularly, the large wastes vertically fall under the action of gravity, so that the safety area, namely the S area, can be prevented from being impacted and interfered by the large wastes, and meanwhile, thick sewage in some sewers also basically flows in the M area; the light water phase flows downwards along the body surface of the fall section 9, so the S area is essentially a filtering area after primary filtering, the impurities of the fluid in the S area are obviously reduced, and the shunted fluid is more suitable for sampling detection. In the embodiment, the fall section 9 is a body surface supported by reinforced concrete, a rectangular well (such as a common roadside prefabricated rectangular cement slab cover) is adopted at the upper part (ground layer) of the whole height fall region, and the widened rectangular well is also beneficial for later-stage personnel to enter and maintain, so that harmful gases such as methane and the like can be rapidly flowed away.

Further, the height difference region is a widening region, and as shown in the top view 4, the upstream pipe 8 is a common sewer pipe. The height drop zone in this embodiment is provided with the conical connecting body 7, the conical connecting body 7 is connected to the lower end of the upstream pipeline 8, and the narrow-top and wide-bottom surface formed by the inner cavity 2 of the conical connecting body 7 is beneficial to spreading out the water left from the upstream pipeline 8, so that the flow of the water in unit area is reduced, and the drop section 9 is ensured to better play a corresponding role. In this embodiment, the horizontal width of the lower end of the conical connecting body 7 is 1 to 3 times the diameter of the pipe cavity 1 of the upstream pipe 8, and then in order to better promote the water to be guided to the fall section 9, the upper end of the fall section 9 is set to be the arc-shaped surface 3, so as to improve the flow of the part of the fluid along the fall section 9. In this embodiment, the connection section at the lower end of the drop height section 9 is an inclined gradually narrowing connection section 4, the inclined connection section 4 is mainly used for preventing the bottle body 14 from being submerged when the water flow is large, the inclined plane is formed on the connection section 4 for improving the downflow speed of the water body, and the lower end of the connection section 4 is connected with the downstream pipeline 5.

Further, the inward inclined surface of the fall section 9 forms an included angle a with the vertical line 9-1, and the included angle a is an acute angle. In the embodiment, the included angle a = 15-35 degrees is preferably selected, and the selection is favorable for the U-shaped water diversion plate to collect the water body under the angle.

Further, the water distributor also comprises U-shaped water guide plates 11, wherein the U-shaped water guide plates 11 are distributed at the middle lower part of the fall section; the bottle bodies 14 are distributed below one end of the U-shaped diversion plate 11. In this embodiment, the U-shaped diversion plate 11 is fixed to the drop section 9 through the chucking bracing piece 12, just the U-shaped diversion plate 11 with can reserve the clearance between the drop section 9, in this embodiment, the U-shaped diversion plate 11 is the slope installation, can do benefit to the collection of water sample and flow like this, and simultaneously, as shown in fig. 2, the U-shaped diversion plate 11 is narrow-down wide structure, because the drop section 9 is the inside slope of lower part, then under the U-shaped diversion plate 11 also slope installation, its lower part just distributes toward inboard more, consequently, through with the preparation of the structure of narrow-down wide is pressed to the U-shaped diversion plate 11, is favorable to better collection enough water sample. In order to be more beneficial to the collecting effect of the U-shaped water diversion plate 11 on a water sample, a plurality of horizontal raised lines 10 are arranged on the surface of the fall section 9 of the height fall area, so that the water sample flowing along the fall section 9 is promoted to directly fall into the U-shaped water diversion plate 11 through the projections of the horizontal raised lines 10. Namely, the U-shaped water diversion plate 11 is better taken by the horizontal convex strips 10, the water is collected by the dripping effect of the horizontal convex strips 10 instead of directly contacting the U-shaped water diversion plate 11 with the surface of the fall section 9 to obtain a water sample, so that the phenomenon that flocculent impurities fall into the U-shaped water diversion plate 11 directly through the surface of the fall section 9 (attached to the fall section 9) in a long period to cause sampling blockage can be reduced. Of course, the sampling mode provided with the horizontal convex strip 10 is only one specific sampling mode, and does not exclude a mode that the U-shaped diversion plate 11 can be tightly attached to the surface of the fall section 9 for sampling. These all belong to the technical scope to be protected by the present invention. In this embodiment, as shown in fig. 4, a sample bottle placement area 6 is provided, the upper portion of the sample bottle placement area 6 is separated by a concrete floor, the bottle bodies 14 are distributed in a space below the floor, and the bottom surface of the sample bottle placement area 6 is communicated with the connecting section 4, so as to facilitate the flow of the sample water flowing out of the bottle bodies 14. In this embodiment, the bottle body 14 is fixed to the drop height section 9 by fixing rods 15 using steel nails 16, and is distributed below the lower end of the U-shaped water guide plate 11, so that a certain height interval can be maintained during distribution, and the water flowing out from the lower end outlet of the U-shaped water guide plate 11 washes the conical part at the upper part of the bottle body 14, so that the conical part can be kept from being blocked for a long time.

Furthermore, a filter screen or a circular pipe body is arranged above the U-shaped diversion plate 11 in some embodiments; the filter screen or the lower extreme of circular body distributes the inner chamber top of U-shaped diversion board. In the concrete implementation, the following specific embodiments are provided:
