Problems solved by technology
At present, due to the late start of nuclear power development in my country and the limitation of sampling conditions, there is no special tool for sampling waste resin in nuclear power plants in my country.
Existing sediment sampling tools are mainly used in oceans, ponds and other water areas. Due to the limitations of the use environment and device structure, they are not suitable for sampling waste resin with small particles and certain radioactivity.

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, a hand-held water body sediment sampler includes a force applying part and a sampling part. Wherein the force-applying parts include an annular handle 1 , a connecting rod 2 , a connecting rod 10 and a hand wheel 3 . The lower end of the ring handle 1 is welded to the connecting rod 2; there are three cylinders on the connecting rod 2, which are respectively used as the rotation axis of the hand wheel 3 and the positioning axes of the nut 4 and the nut 5; the steel wire ropes 7-1 and 7-2 pass through the limit ring 6 Finally, they are respectively connected to the hand wheel 3 through the holes on the cylinders corresponding to the nut 4 and the nut 5, and the two steel wire ropes are wound on the hand wheel in opposite directions, so that when the hand wheel rotates in different directions, the steel wire ropes 7- 1 and 7-...

The invention discloses hand-held water body deposit sampler of a nuclear power station. The sampler comprises a force application member and a sampling member. The force application member comprises a handle, a connection rod, a hand wheel; the handle is connected at one end of the connection rod, the hand wheel is freely rotationally fixed on the connection rod. The sampling member comprises sampling barrel and rotary seal door; upper end of square sampling barrel is connected with the connection rod and is provided with a through circular hole; the rotary seal door pivots around lower end of the square sampling barrel and is connected with hand wheel through steel wire so that lower end of square sampling barrel can open or close. The sampling device is suitable for small range sampling at fixed point of limited space of nuclear power station.
Description
technical field [0001] The invention belongs to the technical field of equipment for removing radioactive objects or materials from a reactor discharge area by a mechanical method, and in particular relates to a hand-held water body sediment sampler for a nuclear power plant. Background technique [0002] Determining the resin composition and the specific activity of radionuclides in the waste resin storage tank of nuclear power plants is the basic means of studying waste resin in nuclear power plants, and it is also one of the main tasks of solid waste treatment in nuclear power plants. At present, due to the late start of nuclear power development in my country and the limitation of sampling conditions, there is no special tool for sampling waste resin in nuclear power plants in my country. The existing sediment sampling tools are mainly used in oceans, ponds and other water areas. Due to the limitations of the use environment and device structure and other factors, they a...
