Description

Technical Field

[0001] This utility model relates to the field of argon arc welding operation technology, specifically to a wind deflector for boiler argon arc welding. Background Technology

[0002] Argon arc welding is one of the important operations in thermal power plants. The welding quality is one of the key factors that determines the reliable and stable operation of the unit. Argon arc welding is required for routine maintenance and repair of the unit, or for situations such as long operation time, corrosion and pipe bursts in some areas, and leakage due to flue gas erosion and wear. When replacing pipes (replacing water-cooled walls) or valves, argon arc welding is required.

[0003] Due to the special nature of argon arc welding, the argon gas cannot be affected by airflow during the welding process. In windy conditions, windproofing measures must be taken. However, due to the pressure difference or location of the boiler water-cooled furnace inside and outside, even if there is a large area of ​​windproofing outside the furnace, there is still wind at the pipe opening, which affects the welding quality. Utility Model Content

[0004] The purpose of this invention is to provide a wind deflector for boiler argon arc welding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind baffle device for boiler argon arc welding, including a wind baffle plate, a flame-retardant sponge layer fixedly connected to the back of the wind baffle plate, a reinforcing plate fixedly connected to the front of the wind baffle plate, a wind baffle plate mounting mechanism provided on the surface of the wind baffle plate, and an auxiliary mechanism provided on the surface of the wind baffle plate.

[0006] The wind deflector mounting mechanism includes a connecting groove located on the front of the wind deflector. A fixing steel plate is installed inside the connecting groove. A first mounting bracket is fixedly connected to the top and bottom of the front of the fixing steel plate.

A mounting base is fixedly connected to the back of the second mounting bracket. A strong magnet is installed inside the mounting base. A handle is fixedly connected to the surface of the mounting base. When needed, the fixing steel plate is installed inside the connecting groove, and the tightness is adjusted by rotating the telescopic adjuster. The second mounting bracket is then pulled out as needed, and the device is fixed on the water-cooled wall pipe by the strong magnet. Due to the strong magnetic force of the strong magnet, this product is designed with a handle for easy placement and removal. This mechanism eliminates the need for personnel inside the furnace to hold the rock wool; personnel can perform other work immediately after placement, and vice versa, thus improving welding efficiency and ensuring welding quality.

[0007] Preferably, the wind deflector mounting mechanism is provided in three sets, which are arranged in a straight line on the front of the wind deflector.

[0008] Preferably, the telescopic adjuster is installed at the connection between the first mounting bracket and the second mounting bracket, and the telescopic extension of the second mounting bracket is controlled by the telescopic adjuster.

[0009] Preferably, the auxiliary mechanism includes a plug-in groove, which is located on the back of the flame-retardant sponge layer. A plug-in seat is inserted into the plug-in groove, and a sealing gasket is fixedly connected to the back of the plug-in seat. Auxiliary connection ports are provided at both ends of the wind baffle, and auxiliary plugs are inserted into the auxiliary connection ports. Before use, a sealing gasket of appropriate width is installed on the surface of the flame-retardant sponge layer according to the pipe spacing of the water-cooled wall to block the gaps in the pipes and further improve the wind-blocking effect. When multiple wind baffles need to be connected together, they can be connected together through the auxiliary connection ports and auxiliary plugs. This method is applicable to water-cooled walls of various sizes and further improves work efficiency.

[0010] Preferably, the wind deflector is connected via an auxiliary connection port and an auxiliary plug, and the plug and sealing gasket are designed to be detachable.
