Description

Technical Field

[0001] The invention relates to the field of underwater welding equipment, in particular to underwater metal welding equipment. Background Art

[0002] Underwater welding, as the name suggests, is a complex welding technology that is performed underwater.

[0003] Underwater welding mainly includes three types: dry welding, partial dry welding and wet welding. Due to the complex underwater conditions, the implementation of dry welding and partial dry welding is not simple and easy. Therefore, for a long time, wet welding has been the main force of underwater welding.

[0004] Wet underwater welding refers to welding directly in deep water, that is, it is carried out under the condition that there is no mechanical barrier between the welding area and the water. This welding is affected by both the ambient water pressure and a variety of variable factors during welding, including the multiple effects of bubbles and diffuse contaminants. That is, during the welding process, a large amount of bubbles overflowing in the welding area and the mass produced by the melting of the solder will further affect the visibility of the welding area, making it difficult for the operator to clearly visually see the welding point after welding for a period of time, making it difficult to maintain the welding work.

[0005] In recent years, there are solutions to deal with bubbles and dispersoids in the welding area by means of suction and discharge pumps, etc. However, considering the specific situation, firstly, the flexibility of operators in underwater construction is limited, and the configuration of equipment such as pump groups will undoubtedly further increase the burden on operators. Secondly, the water flow temperature in the welding area is much higher than the surrounding water temperature, and long-term underwater welding will undoubtedly cause huge heat loss to the human body. Therefore, although the pump group implements suction and discharge treatment for bubbles and dispersoids in the welding area, the suction and discharge treatment does not comprehensively reuse the welding heat. For this reason, based on the principle of not affecting the flexibility of operators, there is an urgent need for an underwater metal welding equipment that can handle bubbles and dispersoids in the welding area with a simple swinging action. Summary of the invention

[0006] The purpose of the present invention is to provide an underwater metal welding device to solve the technical problem that a large amount of bubbles overflow in the welding area and the mass generated by the melting of the solder further affect the visibility of the welding area, making it difficult for the operator to clearly visually see the welding points after welding for a period of time, making it difficult to maintain the welding work.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0039] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0040] Example 1

[0041] In this embodiment, an underwater metal welding device is proposed, including a gear sleeve 3 and an arm sleeve 4 which is arranged in the gear sleeve 3 and can rotate relative to the gear sleeve 3, wherein the arm sleeve 4 extends outward relative to the gear sleeve 3, and the space in the arm sleeve 4 can be adjusted, that is, the arm sleeve 4 can be adapted to change accordingly according to the thickness of the operator's arm, so that the arm sleeve 4 has a wider range of uses.

[0042] Gear brackets 2 are arranged on both sides of the gear sleeve 3, and there is a gap between the gear bracket 2 and the gear sleeve 3. The setting of the gap, on the one hand, is conducive to the meshing and matching with the gear 9 and the gear sleeve 3 mentioned later, and on the other hand, it avoids the problem of the gear bracket 2 touching the gear sleeve 3 and the torque limitation of the gear 9. Therefore, one end of the gear bracket 2 is bypassed by the end of the gear sleeve 3 and extends to the outward extending part of the arm sleeve 4 to implement the above technical solution.

[0043] A gear 9 is arranged at the gear sleeve 3, and the gear 9 extends into the rotation path of the gear sleeve 3 and is meshed with the gear sleeve 3. In addition, an extension plate 7 is installed in the area of ​​the gear sleeve 3 not covered by the gear bracket 2, and the extension plate 7 extends outward so that the range of movement of the extension plate 7 is limited between the gear brackets 2. It should be noted that a counterweight 8 is installed at the end of the extension plate 7 extending outward.

[0044] A guide cover 6 is arranged outwardly along the axial position of the gear 9, and a vortex producing part 5 that can rotate relative to the guide cover 6 is provided inside the guide cover 6. The vortex producing part 5 penetrates the guide cover 6 and extends to the axial position of the gear 9. When the gear sleeve 3 applies torque to the gear 9, the vortex producing part 5 generates a vortex in the guide cover 6 to attract bubbles and welding dispersions.

[0045] See also Figure 1-10 In this embodiment, an underwater welding device is proposed to process bubbles and dispersions produced at welding points based on the rotation of the operator's arm. The underwater welding device is combined with a gear bracket 2, a gear sleeve 3, an arm sleeve 4, a vortex production part 5, a guide cover 6, an extension plate 7, a counterweight 8 and a gear 9, etc., and is intended to lock the arm sleeve 4 to the operator's arm to obtain the kinetic energy generated when the arm rotates, so that the arm sleeve 4 and other components reach the corresponding rotation position before the gear sleeve 3, the extension plate 7 and the counterweight 8 and other components, so that when the counterweight 8 is subjected to the action of gravity, the gear sleeve 3 connected to the counterweight 8 at an interval is meshed with the gear 9 set at the gear bracket 2, thereby intercepting the kinetic energy generated when the counterweight 8 falls, and the vortex produced by the vortex production part 5 rotating in the guide cover 6 to generate a vortex to express it.

[0046] The specific structures of the gear bracket 2, the arm sleeve 4, the vortex production member 5, the guide cover 6 and the extension plate 7 are further described below:

[0047] The vortex production part 5 includes a one-way spiral sleeve 53 and a shaft tube 51 which is trapped in the one-way spiral sleeve 53 and extends outward to the gear 9, wherein the shaft tube 51 is unidirectionally clamped and adapted with the one-way spiral sleeve 53, so that the one-way spiral sleeve 53 can only obtain the torque applied by one rotation direction of the shaft tube 51;

[0048] For specific one-way card adapter conditions, please refer to Fig.10 A plurality of angular protrusions are arranged on the inner wall of the one-way spiral sleeve 53. In addition, a plurality of blocks are arranged on the outer wall of the shaft tube 51 and are in the same horizontal plane as the plurality of angular protrusions. The plurality of blocks are rotatably mounted on the shaft tube 51, and spring plates are installed at appropriate positions between the blocks and the shaft tube 51, so that when the shaft tube 51 rotates forward, the plurality of angular protrusions and the plurality of blocks slide and rub against each other. On the contrary, when the shaft tube 51 rotates reversely, the plurality of angular protrusions and the plurality of blocks are engaged with each other.

[0049] The key point of the one-way clamping adaptation between the shaft tube 51 and the one-way spiral sleeve 53 is that after the shaft tube 51 and the one-way spiral sleeve 53 generate a vortex in one direction, the vortex caused by the reverse rotation of the one-way spiral sleeve 53 must not be destroyed when the shaft tube 51 rotates in the reverse direction, and even bubbles and diffused matter may flow back outward from the guide cover 6.

[0050] In addition, a plurality of holes 52 are provided on the surface of the shaft tube 51, and the positions of the plurality of holes are close to the junction of the shaft tube 51 and the guide cover 6, so that the end of the vortex generated in the guide cover 6 directly points to the plurality of holes 52. It should be noted that a bubble poking tip 54 is installed at one end of the shaft tube 51, and the bubble poking tip 54 extends outward from the cover opening of the guide cover 6.

[0051] The guide cover 6 includes a guide cover body 61 and a support rod 62 connected to the guide cover body 61 so that the guide cover body 61 is suspended directly above the gear 9, wherein at least one support rod 62 is provided, and the other end of the support rod 62 is fixed to the gear bracket 2. In addition, the guide cover body 61 is a tube with a gradually increasing diameter.

[0052] The gear bracket 2 includes a bracket body 21 and a support rod assembly groove 22 arranged at the bracket body 21 for matching with the support rod 62. It should be noted that the bracket body 21 is an L-shaped frame, which bypasses the gear sleeve 3 and is combined with the arm sleeve 4.

[0053] The arm sleeve 4 comprises a sleeve 41 and a bag sleeve 42 arranged in the sleeve 41 , wherein the sleeve 41 extends outward relative to the tooth sleeve 3 , and the bag sleeve 42 is filled with an inert gas.

[0054] The extension plate 7 has a plurality of small holes on its surface, and the plurality of small holes are used to allow water to quickly pass through the plurality of small holes when the extension plate 7 is turned over underwater.

[0055] In combination with the above, the specific working principle of this embodiment is described:

[0056] ① The cuff 42 is depressurized, so that the combination of the sleeve 41 and the cuff 42 is much larger than the size of the operator's hand. Then, the combination is trapped along the hand at the position of the operator's arm. After the specific trapping position is determined, inert gas is injected into the cuff 42 to make the cuff 42 firmly trapped on the arm. When the arm is repeatedly turned over, the combination will not deviate;

[0057] ② When sinking to a specific welding area to perform welding work, one end of an extension tube such as a hose is installed at the expanded end of the guide cover body 61 (the other end of the hose directly points to the welding point), so that the suction force generated by the vortex production part 5 acts more directly on the welding point;

[0058] ③ When there are bubbles and diffuse materials that affect the visual clarity, rotate the arm, and the arm sleeve 4 and other components that are locked in the arm reach the corresponding rotation position before the gear sleeve 3, extension plate 7 and counterweight 8 and other components, so that when the counterweight 8 is affected by gravity, the gear sleeve 3 fixed at a distance from the counterweight 8 meshes and matches with the gear 9 set at the gear bracket 2, thereby intercepting the kinetic energy generated when the counterweight 8 falls, and the vortex generating part 5 rotates in the guide cover 6 to generate a vortex to express it.

[0059] Further explanation of this embodiment:

[0060] See also Figure 1-4 The vortex production part 5 includes a one-way spiral sleeve 53 and a shaft tube 51 that is trapped in the one-way spiral sleeve 53 and extends outward to the gear 9, wherein the shaft tube 51 is unidirectionally clamped and adapted with the one-way spiral sleeve 53, so that the one-way spiral sleeve 53 has and can only obtain the torque applied by one rotation direction of the shaft tube 51. In addition, a plurality of holes 52 are opened on the surface of the shaft tube 51, and the positions of the plurality of holes are close to the junction of the shaft tube 51 and the guide cover 6, so that the end of the vortex generated in the guide cover 6 directly points to the plurality of holes 52. Based on this, the connecting pipe joint 1 is rotated at the other end of the shaft tube 51. It should be noted that the pipe joint 1 and the heat preservation component (the heat preservation component can be a heat preservation box placed on the abdomen or chest, or a hose wrapped around the arm) are plug-in and adapted, that is, the heat-rich water flow is guided to flow into the heat preservation component to keep the operator's arms or key parts of the body warm, so as to avoid local joint stiffness or even hypothermia caused by long-term manual work.

[0061] It should be noted that the heat-rich water flowing in the thermal insulation component must be discharged away from the welding area, that is, to avoid in-and-out discharge that affects the visibility of the welding area.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
