[0002] With the increasing development of inter-basin water diversion projects, the steel pipes used in water supply projects have large diameters and thick walls, and welding quality is particularly important. In windy and cold areas, wind will enter the welding area along the pipe, causing the welding force to decrease, the temperature in the welding area to change dramatically, the welding melting effect to weaken, and the wind speed will cause the welding arc to be unstable. The shielding gas cannot completely protect the molten pool, and more nitrogen holes will appear, which directly affects the welding quality. Since the single-section pipeline is long, it is not economical to set up a warm shed at the full welding end for welding in winter. Utility Model Content

[0008] A further technical solution is that a second groove is provided on the end surface of the plate body away from the cover body, and the number and position of the second groove correspond to the first groove.

[0009] A further technical solution is that the radial width of groove 1 is 3 cm and the depth is 0.8 cm.

[0010] A further technical solution is to arrange a battery on the cover plate, and the battery supplies power to all electromagnetic induction coils.

[0011] A further technical solution is to provide reinforcing ribs on the cover body.

[0012] A further technical solution is that the cover plate is made of resin material.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 4 A windshield cover plate 1 for pipeline welding is provided with a magnet.

[0022] When in use, by setting a magnet on the cover plate 1, the cover plate 1 can be fixed at the opening of the pipe 6 by magnetic attraction, so as to prevent wind from entering the welding area along the pipe 6, thereby avoiding affecting the welding quality.

[0023] The magnet is an electromagnetic induction coil 2, and the electromagnetic induction coil 2 includes multiple electromagnetic induction coils 2 with different diameters, and the multiple electromagnetic induction coils 2 are coaxially arranged. The cover plate 1 includes a cover body 7 and a plate body 8, and the plate body 8 is provided with a circular groove 3, and the size and number of the groove 3 match the electromagnetic induction coil 2. The electromagnetic induction coil 2 is arranged inside the corresponding groove 3, and the cover body 7 is located on the end surface of the plate body 8 with the groove 3 and fixed thereto. The magnet adopts an electromagnetic induction coil 2. When the cover plate 1 is installed, the electromagnetic induction coil 2 is energized to generate magnetism and can be adsorbed at the mouth of the pipe 6. The cover plate 1 is provided with a circular groove 3, and the groove 3 includes multiple grooves of different diameters. An electromagnetic induction coil 2 is arranged in each groove 3, and multiple grooves 3 can adapt to pipes 6 of various different diameters.

[0024] The magnet can also be a permanent magnet, for example, a magnet. In this case, the installation position and proficiency of the magnet only need to adapt to a variety of pipes 6 with different diameters, but this method is more laborious to disassemble than the electromagnetic induction coil 2.

[0025] A groove 29 is provided on the plate body 8 at the end surface away from the cover body 7. The number and position of the groove 29 correspond to the groove 1 3. The provision of the groove 29 helps to improve the stability of the cover plate 1 when installed at the mouth of the pipe 6. During installation, the pipe mouth is placed in the groove 29 of corresponding size, which can improve the stability in the radial direction.

[0026] The radial width of the groove 3 is 3 cm, the depth is 0.8 cm, the thickness of the cover plate 1 is 2 cm, a battery 4 is arranged on the cover plate 1, the battery 4 supplies power to all electromagnetic induction coils 2, a reinforcing rib 5 is arranged on the cover body 7, and the cover plate 1 is made of resin material.

[0027] The battery 4 has a power display screen, and the reinforcing rib 5 is buried with wires from the battery 4 to the electromagnetic induction coil 2. This product is provided with three grooves 3 with electromagnetic induction coils 2, and the three switches are controlled separately to adapt to three different pipe 6 diameters. Because a welding pit needs to be dug here when the port is welded, the flexible adaptability of the cover plate 1 will not be affected when the size is larger than the pipe diameter. Before welding, the wind shield cover plate 1 is covered on the pipe 6. After the battery 4 switch is powered on, the electromagnetic induction coil 2 in the groove 3 generates magnetism and attracts the welded steel pipe to block the air intake channel along the pipe 6. After the welding is completed, the battery 4 switch is turned off, and the magnetism in the groove 3 disappears, making it convenient to remove the wind shield cover plate 1, and thus the construction quality of all pipelines is ensured.

[0028] The above are only preferred embodiments of the present invention.
