Problems solved by technology

The movement and support scheme adopted in Document 3 can only realize the movement in the straight pipe, and cannot adapt to the curved pipe with various angles; at the same time, although the two-stage parallelogram movement structure of the nozzle can achieve a large stretch ratio, the four sets of small wheels The maximum extension of the supporting positioning structure is less than 2 times the minimum extension. Therefore, for a larger inner diameter of the pipe, the envelope size of the designed robot is difficult to achieve a compact structure.

Embodiment 1

[0037] In this embodiment, the pipeline cleaning robot of the tertiary cooling water circulation loop of the nuclear power plant adopts the remote control mode of cable dragging, and includes the casing 2, the cleaning operation module, the mobile support module, the drive control system and the battery.

[0038] Such as Figure 6As shown, the housing 2 as a whole is a cylinder with a through hole in the middle, and several depressions are provided on the outer wall of the cylinder.

[0039] Such as figure 1 , figure 2 As shown, the cleaning operation module includes a rotary base 1 and several brush-type cleaning operation arms 3, the rotary base 1 is installed on the front end surface of the housing 2, and the cleaning operation arm 3 and the rotary base 1 phase connection. Specifically, the rotary base 1 is a cylindrical structure, which drives the cleaning arm 3 to slowly revolve around the rotary base 1 through its own rotation; the cleaning arm 3 is a sleeve-shaped s...

Embodiment 2

[0044] The difference between this embodiment and embodiment 1 is:

[0045] The size of the housing 2 is a cylinder with a diameter of Φ500mm.

[0046] Such as figure 2 As shown, the number of the cleaning operation arms 3 and the number of the support arms 4 are 3, when the robot switches from the initial state to the cleaning operation state, the 3 cleaning operation arms 3 move from the recess of the outer wall of the housing 2 to Flip forward, and the three support arms 4 are simultaneously extended to the rear and outside. Wherein, the deployment of the cleaning operation arm 3 is realized by its own two-stage telescopic sleeve structure, and the deployment of the support arm 4 is realized by its own double parallelogram extension structure.

[0047] The drive control system is filled with tantalum fiber material or lead rubber and other modified composite materials with anti-radiation function to improve the survival performance of the robot in the radiation environme...

Abstract

The invention belongs to the technical field of application of special robots, and in particular relates to a pipeline cleaning robot for a three-stage cooling water circulation loop of a nuclear power plant. The present invention includes a casing, a cleaning operation module, a mobile support module, a drive control system and a battery: the cleaning operation module includes a rotary base and several brush-type cleaning operation arms, and the rotary base is installed on the On the front end, the cleaning operation arm is connected to the rotary base; the mobile support module includes several support arms with rollers at the end; the drive control system is installed inside the through hole of the shell, and is used for the expansion and contraction of each part of the robot. 1. Rotation provides drive; the battery is installed in the recess on the outer wall of the housing to provide power for the robot. The invention has compact structure, strong adaptability to the change range of the inner diameter of the pipeline, and can clean the pipeline of the tertiary cooling water circulation loop of the nuclear power plant.

Description

technical field [0001] The invention belongs to the technical field of application of special robots, and in particular relates to a pipeline cleaning robot for a three-stage cooling water circulation loop of a nuclear power plant. Background technique [0002] During the long-term use of the tertiary cooling water circulation loop of nuclear power plants, there must be a large amount of foreign matter attached to the pipes. The use of robot technology to clean foreign matter in nuclear power plant pipelines is currently a research hotspot in the field of nuclear power robots. For the tertiary circuit of nuclear power plants, its diameter is generally larger, and due to the use of open seawater circulation, it is easier to attach a large number of microorganisms, carbohydrates, protein layers, and various marine organisms and shellfish proliferation layers to the inner wall of the suction pipe, resulting in pipe The dirt deposits on the inner wall and is uneven, and its cle...
