Problems solved by technology

However, rainwater and sewage are mixed in combined drainage pipes, limited by the depth of the well and safety considerations, so sampling is difficult
Piston-type suction sampler can be used to check the sediment in the bottom of the combined system, but it is not easy to sample the sediment in the side wall pipe of the inspection well (that is, the horizontal drainage pipe), and there is no instrument available yet

Embodiment 2

[0044] Embodiment 2.1: the device that is used for urban sewer sediment collection, with embodiment 1.1, difference is: vertical bar connects vertical extension bar, 1, long 78.4cm, vertical bar and horizontal bar take bearing connection , foldable.

[0045] Embodiment 2.2: the device that is used for urban sewer sediment collection, with embodiment 1.1, difference is: vertical rod connects vertical extension rod, 1, long 1m, vertical rod and horizontal rod take bearing connection, foldable.

[0046] Workflow: (1) Open the folded two rods from the toolbox, keep the vertical rod and the horizontal rod vertical, and decide whether to connect the extension rod according to the depth of the well. (2) Place the collection bucket in the slot of the horizontal bar to determine the position and then fix the collection bucket position through the locking device. (3) Open and fix the handle of the vertical rod, hold the handle and slowly put the device into the confluence inspection w...

Embodiment 3

[0050] Embodiment 3.2: the device that is used for urban sewer sediment collection, it comprises vertical rod, and this vertical rod connects one end of horizontal rod, and this horizontal rod comprises locking device, and the other end of described horizontal rod connects collection bucket, The collection bucket is fixed on the horizontal bar through a blocking device, the horizontal bar is connected with the vertical bar by a bearing, the horizontal bar includes a collection bucket slot, and the bottom of the collection bucket includes a base. The base is embedded in the slot of the collection bucket of the horizontal rod, thereby being connected to the horizontal rod. After the collection bucket is installed, the side facing the vertical rod includes a bayonet pin, so as to cooperate with the locking device , and fasten the location of the collection bucket, the cross section of the collection bucket is cylindrical, the height of the collection bucket is 15cm, and the side w...

Abstract

A device for collecting sediment in urban drainage pipes, which includes a vertical rod connected to one end of a horizontal rod, the horizontal rod includes a locking device, the other end of the horizontal rod is connected to a collection bucket, and the collected The bucket is fixed on the horizontal bar through a locking device, and the horizontal bar is connected with the vertical bar by a bearing. The horizontal bar includes a collection bucket slot, and the bottom of the collection bucket includes a base. Embedded in the collection bucket slot of the horizontal rod, so as to be connected to the horizontal rod, the side of the collection bucket facing the vertical rod after installation includes a detent, so as to cooperate with the locking device, and The collection bucket is fastened and positioned, and the side of the collection bucket facing away from the vertical rod is open after installation, and the cross section of the collection bucket is an arc shape greater than 270 degrees. The height is 15cm, and the collection bucket is made of alloy material, the device is easy to install and light in weight.

Description

technical field [0001] The invention relates to a sediment collection device, in particular to a sediment collection device used in the side wall pipe of an inspection well in the confluence system of urban drainage pipes. Background technique [0002] In drainage pipes, rainwater runoff and solid pollutants in sewage entering the drainage pipes will cause sedimentation in the pipes. The accumulation of a large amount of sediments will directly lead to a decrease in the flow capacity of the pipes, reduce the drainage capacity of the pipes, and frequently cause urban waterlogging. During heavy rain, the runoff erosion will cause the sediment to be suspended again into the water body, resulting in the release of pollutants stored in the sediment, forming an impact pollution load, turning non-point source pollution into point source pollution, and polluting the receiving water body threaten. Therefore, collecting sediments to understand the sediment deposition status, pollutan...
