[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] As shown in the figure, a protective device for flame cutting includes a metal shaping module 3, a magnet 2, a bow end fixing module 4, a stern end fixing module 5, and a combination module 1. The metal shaping module 3 is obtained by cutting a section of metal threaded hose into a semi-circular shape. The semi-circular metal threaded hose can be extended, retracted, and bent, and is used to adjust the length and curvature of the device. The bow-end fixing module 4 is a groove with open sides. The open end face is connected to the metal shaping module 3 and is used to pull the metal shaping module 3 to adjust its length and curvature. The stern-end fixing module 5 is a side-open groove, with one end connected to the metal shaping module 3; The combined module 1 is a slot with open sides, which is connected to the other end of the stern fixed module 5; Magnets 2 are placed on both sides of the combined module 1 to attract the device to the lower end of the cutting seam on the opposite side of the cutting position. By protecting the construction site, the protection of the entire construction area is solved, and the protection is completed from the root, so that there is no need to protect other equipment and cables. Among them, the open grooves of the bow fixing module 4, the stern fixing module 5 and the combined module 1 are coplanar with the open part of the semi-circular metal threaded hose of the metal shaping module 3, forming an open fireproof groove that faces the cutting seam, which is used to fill fireproof materials and collect molten slag.

[0018] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: Since the bow fixing module 4, stern fixing module 5, combined module 1 and metal shaping module 3 form a fireproof groove with open sides, fireproof materials can be filled into the fireproof groove, thereby reducing the use of fireproof materials and avoiding waste of fireproof materials.

[0019] Because the device is attached to the lower end of the cut seam on the opposite side of the cutting position by magnet 2, the fireproof groove is attached to the opposite side of the cutting position. The fireproof groove can collect molten slag, which reduces the use of fireproof materials and the occupation of monitoring personnel, thus achieving protection of the construction site. This solves the protection work of the entire construction area, completing the protection from the root, and eliminating the need to protect other equipment and cables.

[0020] Since the metal shaping module 3 is a semi-circular metal threaded hose, the device can be freely extended in terms of cutting length and can be moved freely, making it very easy to use.

[0021] To ensure the stability of the structure in this embodiment, the two ends of the metal shaping module 3 are welded to the stern fixing module 5 and the bow fixing module 4, respectively.

[0022] To further ensure the stability of the structure in this embodiment, the combined module 1 and the stern fixing module 5 are connected and fixed by a wedge connection or rivets 6, so that the combined module 1 and the stern fixing module 5, the metal shaping module 3 and the bow fixing module 4 connected in sequence form a whole.

[0023] To optimize the structure of this embodiment, the magnet 2 is magnetically connected to the cutting position, and the number of magnets 2 used is determined according to the actual situation on site.

[0024] This embodiment addresses the protection of the entire construction area by protecting the construction work station, achieving protection at its source without requiring additional protection for other equipment and cables. The device is secured with magnet 2, adsorbing and fixing it to the opposite side of the cutting position. Its multi-segment, multi-angle modular design can meet the needs of cutting operations of any size and angle on site, requiring minimal additional devices and materials. The cutting length can be freely extended and moved, making it very easy to use. A small amount of fireproof material is needed to meet on-site requirements, significantly reducing the use of fireproof materials and the need for monitoring personnel. This device can provide source protection for shipbuilding repair, installation, and external plate and structural modifications involving extensive hot work cutting operations. It effectively protects against both shell plate butt welds and detachable plate cutting. Before cutting, the device is placed directly below the cutting seam and secured to the plate with magnets. Fireproof and cooling materials are pre-filled inside. After cutting and cooling to room temperature, the device is removed, and the collected slag and other debris are transferred to a designated storage location.

[0025] The working process of this embodiment: Step 1: Before starting work, fill the device with fireproof and cooling material.

[0026] Step 2: Mark the reverse side of the cut board with lines.

[0027] Step 3: Align the center of the device with the markings on the plate, and connect the combination module 1, metal shaping module 3, bow end fixing module 4, and stern end fixing module 5 of the device together according to the site requirements. Then, fix the device to the cutting steel plate using magnet 2.

[0028] Step 4: Adjust the curvature of the metal shaping module 3 according to the markings to fit the cutting seam.

[0029] Step 5: Cut the steel plate from the front.

[0030] Step 6: After the device has cooled to room temperature, dismantle the device and transfer the internal molten slag to the storage location.

[0031] Step 7: Maintenance. Clean and maintain the device to ensure normal operation and lifespan.

[0032] Features of this embodiment: First, this embodiment is convenient and flexible, and its length can be adjusted at any time as needed to adapt to different working scenarios.

[0033] Second, this embodiment requires less construction work, reduces the need for large-area protection, and improves work efficiency.

[0034] Third, this embodiment uses metal materials as the main body, which can be reused and saves protection costs.

[0035] Finally, it should be noted that: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
