Embodiment 1

[0023] Such as Figure 1 to Figure 7 As shown, the in-situ sampling device 2 for urban drainage pipeline sediments includes a support device 1 and a sampling device 2. The sampling device 2 includes a sampling rod 21 and a sampler 22 connected to the end of the sampling rod 21; the supporting device 1 includes a support rod 11, The movement of the sampling rod 21 relative to the support rod 11 enables the sampler 22 to complete the sampling action. The sampler 22 in this embodiment is made of stainless steel and is used to collect samples. The shape is an approximately rectangular parallelepiped stainless steel box with an open front end, about 40 cm long and about 30 cm high. The sampling rod 21 is used for collecting samples, and the support rod 11 is used for stabilizing the device.

[0024] Specifically, in this embodiment, the baffle 3 for opening the closed sampler 22 is also included. In this embodiment, the baffle 3 is mainly used to seal the sampler 22 after the sam...

Abstract

The invention discloses an urban drainage pipeline sediment in-situ sampling device which comprises a supporting device and a sampling device. The sampling device comprises a sampling rod and a sampler connected with a tail end of the sampling rod; and the supporting device comprises a supporting rod, and the sampling rod moves relative to the supporting rod to enable the sampler to complete sampling action. A baffle used for opening and closing the sampler is also included. The baffle is fixed to the tail end of the supporting rod. The sampling rod comprises a horizontal rod and a vertical rod, a sliding clamping groove is arranged in the horizontal rod of the sampling rod, the supporting rod comprises a transverse rod and a vertical rod, a sliding rod is fixedly arranged on the transverse rod and embedded into the sliding clamping groove, and the sliding clamping groove and the sliding rod slide relatively. Supporting foot stands are fixedly arranged at the bottom of the supporting rod. In the invention, manual well descending sampling is not needed when a sediment is sampled, safety is improved, double operating rods (namely the sampling rod and the supporting rod) are designedin a matched mode, operation is easy and convenient, labor is saved, convenience and rapidness are achieved, safety and reliability are achieved too, an application range is wide, applicability is high, and integrity of the sediment in the sampling process is guaranteed.

Description

technical field [0001] The invention relates to an in-situ sampling device, in particular to an in-situ sampling device for urban drainage pipe sediments, belonging to the technical field of environmental protection, and in particular to the technical field of sediment sampling. Background technique [0002] The urban drainage system is an engineering facility system that removes and treats urban domestic and industrial sewage and rainwater runoff. It can effectively avoid the hazards of sewage and storm water, and ensure the orderly progress of urban life and production. During long-term operation, due to imperfect management safeguards, defects in the pipeline itself, and unreasonable design, the deposition of suspended solid particles in the drainage pipeline is very easy to occur. This phenomenon will lead to insufficient operating capacity of drainage pipes, and even local blockage; at the same time, the sediment contains a large amount of organic matter, and most of th...
