Description

A special cleaning device for nuclear power pool corners

Technical Field

The invention relates to the technical field of nuclear power water pool cleaning equipment, and in particular to a nuclear power water pool corner special cleaning equipment.

Background Art

In nuclear reaction technology, nuclear fuel is usually loaded into nuclear fuel cladding, and then multiple groups of cladding are assembled and neatly hoisted into a nuclear power pool, and then the nuclear power pool is filled with boric acid water to shield the radiation generated in the nuclear reactor.

After the nuclear fuel is exhausted, the nuclear fuel cell needs to be replaced. During the replacement of nuclear fuel, the stains on the inner wall of the nuclear power pool generated during the long-term immersion process also need to be cleaned. Since the nuclear power pool is very deep and the side wall area is large, during the cleaning process of the nuclear power pool, it is usually necessary to drain the boric acid water in the pool and then hoist it into the automatic cleaning robot, which will automatically clean the inner wall of the nuclear power pool.

At present, the efficiency of robots in cleaning nuclear power pools has been greatly improved. The robots still mainly rely on roller brushes to plan paths for the bottom and side walls of the pools. However, there are always dead angles between the two ends of the roller brushes and the vertical walls around the machine path that cannot be contacted. The robots are also prone to pushing impurities into the corners of the pools during their forward movement, requiring staff to go down into the pools to clean them, affecting the cleaning efficiency.

Specifically, the first cleaning assembly includes at least two first roller brushes 3, and the second cleaning assembly includes at least two second roller brushes 4. In the embodiment of the present application, two first roller brushes 3 and two second roller brushes 4 are provided, and the two roller brushes are arranged in parallel and rotationally on both sides of the first mounting plate 21. The axis of the first roller brush 3 is parallel to the arrangement direction of the mounting frame 1 and the floating frame 2. The second roller brush 4 is arranged in parallel and rotationally on both sides of the second mounting plate 22. The axis of the second roller brush 4 is perpendicular to the axis of the first roller brush 3. The first roller brush 3 is arranged horizontally and one end extends from the edge of the first mounting plate 21 away from the mounting frame 1. The bottom end of the second roller brush 4 is located on the side of the end of the first roller brush 3 away from the mounting frame 1. The floating frame 2 is provided with a first driving member 5 for driving the first roller brush 3 and the second roller brush 4 to rotate.

When the mounting frame 1 is placed on the bottom wall of the pool, the device is moved to the edge of the pool by the first moving component, and the first adsorption component and the second adsorption component are started, so that the first mounting plate 21 and the second mounting plate 22 on the floating frame 2 are closely matched with the bottom wall and the side wall of the pool, and then the second moving component drives the device to move along the angle of the pool. During the movement, the first roller brush 3 and the second roller brush 4 on the floating frame 2 rotate and perform special cleaning on the angle of the pool.

In the embodiment of the present application, the first moving component includes two groups of rollers 18 arranged in parallel, and the two groups of rollers 18 are rotatably mounted on the bottom wall of the mounting frame 1.

Referring to Fig. 3, a connector 23 is fixedly installed on the side wall of the floating frame 2 close to the mounting frame 1. A connecting groove 11 is provided on one side of the mounting frame 1 close to the floating frame 2. The connector 23 is embedded and installed in the connecting groove 11, and the connector 23 can move relatively in the connecting groove 11 on a vertical plane. Specifically, the cross-sections of the connector 23 and the connecting groove 11 are both square. A first connecting frame 24 is vertically slidably installed in the connecting groove 11. The middle part of the first connecting frame 24 is hollowed out, and the connector 23 is connected to the first connecting frame 24 along a horizontal square sliding connection.

Furthermore, steps 141 are provided along the circumference of the outer edges of both sides of the crawler 14, and a baffle 17 is fixed at the opening of the installation cavity 15. The baffle 17 cooperates with the steps 141. When the floating frame 2 walks on the inner wall of the pool through the crawler 14, the baffle 17 can effectively close the gap between the crawler 14 and the inner wall of the installation cavity 15, thereby improving the adsorption effect of the first adsorption component. The negative pressure source can be a negative pressure pump, which can be arranged on the installation frame 1 or on the top of the pool, and the negative pressure pump is connected to the first negative pressure pipe 16 through a hose.

One end of the second negative pressure pipe 31 is relatively fixedly connected to the floating frame 2 and is externally connected to a sewage suction pump. The sewage suction pump can be set on the mounting frame 1 or on the top of the pool. The sewage suction pump is connected to the second negative pressure pipe 31 through a hose. The first cleaning sleeve 32 is coaxially rotatably sleeved on the outer wall of the second negative pressure pipe 31. Specifically, the first cleaning sleeve 32 is connected to the second negative pressure pipe 31 through at least two bearings, so that the first cleaning sleeve 32 is coaxially rotatably connected to the second negative pressure pipe 31.
