Description

Technical Field

[0001] The present invention relates to the field of welding, and particularly to a wind-proof device for welding a membrane water wall. Background Art

[0002] The water wall is the main heat-absorbing part of a boiler. It consists of several rows of steel pipes and is distributed around the furnace of the boiler. The inside of it is filled with flowing water or steam, and it receives the heat of the flame in the boiler furnace from the outside. It mainly absorbs the radiant heat of the high-temperature combustion products in the furnace, and the working medium moves upward in it, being heated and evaporated. A membrane water wall refers to a water wall composed of an airtight tube screen formed by welding flat steel and pipes together.

[0003] A wind-proof device for welding a membrane water wall is disclosed in the patent with the publication number CN221185201U, belonging to the field of membrane water walls. It mainly includes a wind-proof bracket, heat-insulating cotton, and a fixing device. The wind-proof bracket is arranged at the welding point position of the membrane water wall, and a piece of heat-insulating cotton is clamped between the wind-proof bracket and the membrane water wall.

[0004] However, the above device still has certain defects during use. During the welding process by technicians, the eyes are prone to congestion due to the ultraviolet rays generated by the welding arc, which in turn causes eye fatigue. Secondly, during the welding process, when the welding rod is damp, it is easy to cause pores to appear on the weld, affecting the welding quality.

[0018] 3.

[0032] As a further embodiment of the present invention, one end of the air outlet pipe 22 far from the air pump 15 is communicated with an electromagnetic three-way valve 10. The electromagnetic three-way valve 10 is a one-in-two-out three-way valve, whose input end is communicated with the air outlet pipe 22, and its two output ends are respectively communicated with a second corrugated pipe 11 and an external air pipe 9.

[0033] In specific implementation, the position of the second corrugated pipe 11 can be adjusted, which is the basic function of the corrugated pipe and will not be disclosed in detail here. By making the air outlet end of the second corrugated pipe 11 face the weld after welding of the membrane water wall, effective cooling work can be carried out on the weld after welding. At the same time, during this process, the abutting water bag 3 can abut in the middle of the second corrugated pipe 11 and the place where the membrane water wall is being welded, playing a role in preventing wind.

[0034] As a further embodiment of the present invention, one side of the top of one end of the bottom plate 1 is fixedly connected with a water pump 12. The input end of the water pump 12 is communicated with a water outlet pipe 19. One end of the water outlet pipe 19 far from the water pump 12 is communicated with a water tank 18.

At the same time, through the setting of the water pressure valve, the abutting water bag 3 and the cooling water chamber 21 can be filled with water.

[0038] It should be noted that the water pressure preset value is the same as the pressure preset value.

[0039] As a further implementation scheme of the present invention, photovoltaic panels 7 are fixedly connected to both sides of the horizontal end of the return pipe 17, and the ends of the two photovoltaic panels 7 away from the return pipe 17 are fixedly connected to the tops of the two side plates 32 respectively. The vertical end of the return pipe 17 is embedded in the end plate 33, and an annular condenser 16 is embedded in the end plate 33. The vertical end of the return pipe 17 is located on the inner side of the condenser 16. The photovoltaic panel 7 is used to generate electricity, and a battery is embedded in the end plate 33.

[0040] In a specific implementation, the condenser 16 is provided to cool the refluxed water, thereby effectively reducing the water temperature in the water tank 18, so as to facilitate the subsequent water supply to the annular water bag 13 and the abutting water bag 3, so that they can continue to perform the cooling work and effectively circulate the water.

[0041] As a further embodiment of the present invention, the welding gun 6 is arranged at one of the corners of the top of the base plate 1, and the corner is located on the side of the base plate 1 away from the door panel 2. The welding gun 6 is connected to an external power supply, and the external power supply is electrically connected to a current monitoring sensor 30. The current monitoring sensor 30 is connected in series with the welding gun 6, and a double-control switch 31 is connected in series on the side of the welding gun 6 away from the current monitoring sensor 30. One end of the external power supply away from the current monitoring sensor 30 is electrically connected to an electric heating plate 26, and the electric heating plate 26 is a resistance-type heating plate. One end of the external power supply away from the current monitoring sensor 30 is also directly connected to a return wire, and one end of the electric heating plate 26 away from the external power supply is electrically connected to contact one, and one end of the return wire away from the external power supply is electrically connected to contact two. The double-control switch 31 switches between contact one and contact two, and the electric heating plate 26 is embedded in the interior of the base plate 1, and the electric heating plate 26 is located below the placement box 14.

[0042] In a specific implementation, the welding gun 6 is an electric welding gun, and electric welding is achieved by electric current. This technology is a prior art and will not be disclosed in detail herein.

[0043] As a further embodiment of the present invention, the current monitoring sensor 30 is built with a controller, and the controller is used to control the dual-control switch 31 to switch the circuit.

[0044] In specific implementation, the current monitoring sensor 30 is used to monitor the current in the circuit, and the current monitoring sensor 30 is preset to a maximum current preset value and a minimum current preset value. When the current in the circuit is higher than the maximum current preset value, the current monitoring sensor 30 will feedback a first request message to the controller. After receiving the first request message, the controller will generate a first control message and then send the first control message to the double-control switch 31. After receiving the first control message, the double-control switch 31 will switch the circuit from contact point two to contact point one, so that the electric heating plate 26 is connected in series to the circuit; When the current in the circuit is lower than the minimum current preset value, the current monitoring sensor 30 will feedback a second request message to the controller. After receiving the second request message, the controller will generate a second control message and then send the second control message to the double-control switch 31. After receiving the second control message, the double-control switch 31 will switch the circuit from contact point one to contact point two, so that the electric heating plate 26 is disconnected from the circuit, and only the current monitoring sensor 30, the welding torch 6 and the double-control switch 31 are left in the circuit.

[0045] It should be noted that as Figure 10 shown, the letter "A" in the figure is the circuit symbol of the current monitoring sensor 30, representing current, the letter "U" represents alternating current voltage, the letter "M" represents the welding torch 6, and both the letters "A" and "U" are common symbols in existing circuit diagrams and will not be disclosed in detail here. It should be noted that the letter "M" represents a motor in a conventional circuit diagram and only represents the welding torch 6 in the present invention.

[0046] The working principle of the present invention: When the present invention is in use, first, open the door panel 2. After the technician enters the interior of the device, close the door panel 2. Then move the device to the position where the membrane water wall needs to be welded. After moving the device to the position where the membrane water wall needs to be welded, turn on the water pump 12 and the air pump 15. After the water pump 12 is turned on, it will supply water to the abutting water bag 3, thereby causing the abutting water bag 3 to expand. After the abutting water bag 3 expands, control the device to bring the abutting water bag 3 into contact with the membrane water wall. The abutting water bag 3 is soft in texture, so it will fit with the membrane water wall. The abutting water bag 3 fits on the membrane water wall to prevent wind in the space for welding in the middle of the device, which is beneficial to preventing the wind on both sides of the welding area of the membrane water wall from entering the space on one side where the two side plates face each other. At the same time, the fitting of the abutting water bag 3 with the membrane water wall can also prevent wind for the second bamboo joint pipe 11.

[0047] When the device is welding, it can prevent wind for the membrane water wall through two side plates 32 and one end plate 33, blocking the natural wind from the outside. It should be noted that since the membrane water wall is relatively large, the welding of the membrane water wall is usually completed outdoors. And when repairing and welding an old membrane water wall, a lifting ladder is also needed to send technicians to work at high altitude for welding operations.

[0048] After the technician controls the abutting water bag 3 to abut against the membrane water wall, the technician picks up the welding torch 6 to carry out the welding work on the membrane water wall. During the welding process, the overcurrent protection of the welding torch 6 is carried out through the current monitoring sensor 30. When the current inside the welding torch 6 is higher than the current preset value, the circuit is switched through the double-control switch 31, and the electric heating plate 26 is connected in series into the circuit. After the electric heating plate 26 is connected in series into the circuit, it will increase the overall voltage of the circuit, and then reduce the current of the circuit. The current is the ratio of voltage to resistance, and the overall resistance in the series circuit is the sum of the resistances of each component. After the electric heating plate 26 is connected in parallel into the circuit, it can reduce the current of the circuit. On the one hand, it can carry out overcurrent protection for the welding torch 6, and on the other hand, it can also help to avoid the situation that pores appear on the weld during the welding work due to excessive current in the welding torch 6.

[0049] After the electric heating plate 26 is connected in series into the circuit, the electric heating plate 26 will also generate heat, which can then heat the welding rods in the placement box 14, facilitating the drying work of the welding rods in the placement box 14. By drying the welding rods, it helps to avoid the situation that pores appear at the weld of the membrane water wall due to wet welding rods, further reducing the pores on the weld and improving the quality of the weld.

[0050] During the welding process of the membrane water wall, the welding work is carried out between the two side plates 32. The abutting water bags 3 located on the two side plates 32 can play different roles. During the horizontal welding process of the membrane water wall, the two abutting water bags 3 will respectively abut against the unwelded part and the welded part of the membrane water wall. After the water pump 12 is turned on, it will drive the flow of water inside the abutting water bag 3. For the abutting water bag 3 abutting against the unwelded part, the flow of water inside it can cool the unwelded part. Especially for the welding work in summer, the membrane water wall is usually relatively hot. When welding the membrane water wall when it is hot, it is easy to have too high thermal stress after welding the membrane water wall, affecting the subsequent service life. By abutting the membrane water wall with the abutting water bag 3 and through the internal water flow, the position of the membrane water wall to be welded can be cooled, which is beneficial to eliminating the thermal stress caused by the membrane water wall during the subsequent welding work, thereby improving the service life of the membrane water wall and further ensuring the welding quality of the membrane water wall. Secondly, during the welding work in summer, the photovoltaic panel 7 can also shade the technicians, and the air blowing assembly can also improve the coolness of the technicians.

[0051] When technicians are carrying out welding work, especially high-altitude operations, the duration is usually long. Therefore, the long-term welding work will cause the technicians' eyes to become congested and fatigued, and the welding arc will also cause the technicians' eyes to be burned by the ultraviolet rays emitted by it. Through the setting of the welding mask 4, it can protect against the ultraviolet rays emitted by the welding arc during the welding process, improving the safety of the technicians. And after the air pump 15 is turned on, it will extract air from the inside of the welding mask 4 through the first bamboo joint tube 5, the fan-shaped groove 34 and the air holes 35. When the technicians are carrying out welding work, it can drive the air flow around the mask, and reduce the temperature of the technicians' faces through the air flow, playing a certain cooling role for the technicians, which is beneficial to avoiding the occurrence of eye congestion of the technicians due to long-term work.

[0052] After the gas is extracted by the air pump 15, it will enter the electromagnetic three-way valve 10 through the air outlet pipe 22. First, by controlling the electromagnetic three-way valve 10, the air outlet pipe 22 is connected to the second bamboo joint tube 11, and the air outlet end of the second bamboo joint tube 11 is directed towards the weld of the membrane water wall. At this time, the air flow discharged from the second bamboo joint tube 11 can effectively cool the weld. At the same time, the abutting water bag 3 on the same side of the device as the second bamboo joint tube 11 can also cool the welded membrane water wall, which is beneficial to realizing the rapid cooling of the weld and reducing the cooling time of the welding work.

[0053] During the drying process of the welding rod, the technician can also control the electromagnetic three-way valve 10 to connect the air outlet pipe 22 with the external air pipe 9, and then the gas will enter the airbag 27, thereby causing the airbag 27 to expand. After the airbag 27 expands, it will lift the welding rod located in the placement box 14. Since the four sides of the airbag 27 are fixed, the center of the airbag 27 will rise, thereby lifting the welding rod, causing the welding rod to fluctuate, so as to flip the welding rod. When the air pressure in the airbag 27 is higher than the preset value of the air pressure of the air pressure valve, the air pressure valve opens, so that the excess gas in the airbag 27 can enter the cavity 28 through the built-in air pipe 29, and then blow into the placement box 14. The flow of airflow is conducive to the discharge of the humid gas discharged from the welding rod after drying in the placement box 14.

[0054] After the water pump 12 is turned on, it will draw water from the water tank 18 through the outlet pipe 19, and then transport the water flow to the annular water bag 13 through the input pipe 25, so that the water in the annular water bag 13 can flow effectively. At the same time, the pressure valve provided at the connection between the output pipe 24 and the cooling water chamber 21 can make the annular water bag 13 in an expanded state. Through the provision of the annular water bag 13, when there are dust impurities on the surface of the welding rod, the technician passes the welding rod through the inner circle of the annular water bag 13, and cleans and cools the welding rod through the expanded annular water bag 13. After a period of welding work, the technician's eyes may become congested. By picking up the annular water bag 13 and attaching it to the eyes, the eyes can be coldly compressed, which can effectively relieve eye fatigue. At the same time, the flow of water inside the annular water bag 13 can also have a massage effect on the eyes, which can further have a good soothing effect on the technician's eyes.

[0055] When the water pressure in the annular water bag 13 is higher than the preset pressure value of the pressure valve, the pressure valve opens, allowing the water in the annular water bag 13 to enter the cooling water chamber 21. The flow of water in the cooling water chamber 21 can cool the gas in the outlet pipe 22, thereby promoting the working efficiency of the outlet pipe 22 during the subsequent cooling of the weld, and further accelerating the cooling of the weld.

[0056] After entering the cooling water chamber 21, the water will enter the built-in tube 20 through the drain pipe 23, and then enter the two abutting water bags 3 through the built-in tube 20. When the water pressure in the abutting water bags 3 and the collecting pipe 8 is higher than the preset water pressure value of the water pressure valve, the water pressure valve opens, so that the water in the abutting water bags 3 can flow back to the water tank 18 through the return pipe 17. In this process, the condenser 16 is turned on to cool the refluxed water.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and these changes and improvements fall within the scope of the present invention claimed.
