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 in-situ sampling device for urban drainage pipe sediments, which includes a support device and a sampling device. The sampling device includes a sampling rod and a sampler connected to the end of the sampling rod; The movement causes the sampler to complete the sampling action. Also included are flaps to open closed samplers. The baffle is fixed on the end of the support rod. The sampling rod includes a horizontal rod and a vertical rod. A sliding slot is provided on the horizontal rod of the sampling rod. The supporting rod includes a horizontal rod and a vertical rod. A sliding rod is fixedly arranged on the horizontal rod, and the sliding rod is embedded in the sliding slot. The slide bar slides relatively. The bottom of the support rod is fixedly provided with a support tripod. The invention does not need to manually go down to the well to sample the sediment, which improves the safety. The double operation rod (that is, the sampling rod and the support rod) is designed in combination, and the operation is simple, labor-saving, convenient, fast, safe and reliable, and has a wide range of applications and strong applicability. , to ensure the integrity of the sediment during sampling.

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...
