Description

Technical Field

[0001] The utility model belongs to the field of nuclear engineering cleaning tools, in particular to a rolling brush anti-contamination device suitable for desilting a nuclear reactor pool. Background Art

[0002] In the field of nuclear engineering, underwater operations have always faced extremely high risks and challenges. For maintenance work in the field of nuclear engineering, one of the main tasks is to desilt the bottom of the pool in a high-radiation environment. In most cases, it is done by humans going into the water. A few operations use underwater cleaning robots to help humans complete the desilting. For underwater salvage robots, the robots can work underwater and remove the silt at the bottom of the pool through visual system recognition, which can not only ensure the safety of operators, but also improve the desilting efficiency.

[0003] However, the roller brush tools used in existing underwater dredging robots are generally fixedly installed. Although the fixed installation of the roller brush is relatively simple, there are obvious deficiencies in the convenience of disassembly. Especially for operations in a pool environment with a certain degree of nuclear radiation, long-term operations cause some parts of the tools to be contaminated by nuclear radiation to a certain extent, especially the roller brushes that are prone to silt adhesion. The contaminated tools salvaged after the operation is completed pose a safety hazard to the operators, resulting in poor efficiency and safety of nuclear pool dredging operations equipped with fixed roller brush tools in actual applications, and the disassembly and assembly efficiency is too low. In nuclear engineering, the equipment needs to be processed after the operation is completed. The processing process of traditional equipment is too cumbersome, which limits the efficiency of underwater operations. Utility Model Content

[0007] The roller brush tool is mainly composed of a roller brush mounting baffle, a roller brush for dredging, a waterproof motor fixing seat, a waterproof motor and a buoyancy plate; the waterproof motor fixing seat and the buoyancy plate are both fixedly mounted on the top of the roller brush mounting baffle, the buoyancy plate is used to provide buoyancy for the entire device, a waterproof motor is placed in the waterproof motor fixing seat, the roller brush can be mounted on the roller brush mounting baffle so as to rotate around its own axis, and the waterproof motor is connected to the roller brush to drive the roller brush to rotate;

[0008] One end of the mounting bracket is detachably mounted in the strip groove of the roller brush tool mounting seat. When the mounting bracket is connected to the strip groove of the roller brush tool mounting seat, the mounting bracket can move forward and backward in a direction perpendicular to the axis of the roller brush. The other end of the mounting bracket is fixedly connected to the roller brush mounting baffle for driving the roller brush tool to move synchronously.

[0009] Two annular grooves are provided on one side of the mounting bracket close to the roller brush tool mounting seat. When the mounting bracket is connected to the roller brush tool mounting seat, the roller brush tool mounting seat is located between the two annular grooves of the mounting bracket.

[0010] The mounting bracket is equipped with two clips. When the mounting bracket is connected to the roller brush tool mounting seat, the two clips are respectively engaged with the two annular grooves, so that the roller brush tool mounting seat is limited between the two clips, thereby limiting the movement of the roller brush tool mounting seat relative to the mounting bracket, and then locking the relative movement between the mounting plate and the roller brush tool by the clips.

[0011] The roller brush inside the roller brush mounting baffle is connected to the waterproof motor for transmission via a synchronous belt.

[0012] The buckle and the mounting bracket are both made of nylon material which is easy to destroy.

The roller brush is connected to the waterproof motor through a synchronous belt, and one side of the roller brush mounting baffle is fixedly connected to one end of the roller brush tool mounting bracket. The utility model has installation flexibility, and uses a buckle-type installation dredging tool, which is convenient for quick disassembly and assembly after the dredging work is completed in a nuclear radiation environment. In addition, the installation component material is made of plastic, which is convenient for destruction and processing, and prevents the tool from causing radiation hazards to personnel after being contaminated by nuclear radiation. It has good convenience and strong safety.

[0014] Compared with traditional roller brush tools, the roller brush anti-fouling device of the utility model has more convenient disassembly and assembly capabilities and higher safety guarantees.

When the buckle 3 is engaged in the annular groove, the roller brush tool mounting seat 2 can be fixedly connected to the mounting bracket 4 to prevent the roller brush tool mounting seat 2 from moving forward and backward along the axial direction of the mounting bracket 4.

[0024] The roller brush tool is mainly composed of a roller brush mounting baffle 5, a roller brush 6 for dredging, a waterproof motor fixing seat 7, a waterproof motor 8 and a buoyancy plate 9; the waterproof motor fixing seat 7 and the buoyancy plate 9 are both fixedly mounted on the top of the roller brush mounting baffle 5, the buoyancy plate 9 uses a buoyancy material with a relatively low density, such as an epoxy-based glass microbead solid buoyancy material, to provide buoyancy for the entire device, a waterproof motor 8 is placed in the waterproof motor fixing seat 7, the roller brush 6 can be mounted on the roller brush mounting baffle 5 so as to rotate around its own axis, and the waterproof motor 8 is connected to the roller brush 6 to drive the roller brush 6 to rotate;

[0025] One end of the mounting bracket 4 is detachably mounted in the strip groove of the roller brush tool mounting seat 2.
