Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to a membrane type water-cooled wall welding windproof device. Background Art

[0002] The water wall is the primary heat-receiving part of the boiler. It consists of several rows of steel pipes distributed around the boiler furnace. Water or steam flows inside, and the outside receives heat from the boiler furnace flame. It primarily absorbs radiant heat from the high-temperature combustion products in the furnace. The working fluid rises through it, evaporating as it heats. A membrane water wall is composed of airtight panels of flat steel and pipes welded together.

[0003] Patent publication number CN221185201U discloses a membrane water wall welded windbreak device, which belongs to the membrane water wall field.

[0040] In a specific implementation, the air pressure valve is provided with an air pressure preset value. When the air pressure in the airbag 27 is higher than the air pressure preset value, the air pressure valve opens.

[0041] The airbag 27 is of high temperature resistant type. A solenoid valve is provided on one side of the top of the airbag 27. By opening the solenoid valve, the gas in the airbag 27 is released so that the heat emitted by the electric heating plate 26 can be transferred to the welding rod in the placement box 14.

[0042] As a further embodiment of the present invention, the end of the air outlet pipe 22 away from the air pump 15 is connected to the electromagnetic three-way valve 10. The electromagnetic three-way valve 10 is a one-inlet and two-outlet three-way valve. Its input end is connected to the air outlet pipe 22, and its two output ends are respectively connected to the second bamboo tube 11 and the external air pipe 9. The end of the second bamboo tube 11 away from the electromagnetic three-way valve 10 faces the membrane water-cooled wall.

[0043] In specific implementation, the position of the second bamboo tube 11 can be adjusted. This is the basic function of the bamboo tube and will not be disclosed in detail here. By pointing the air outlet end of the second bamboo tube 11 toward the weld after the membrane water-cooled wall is welded, the weld can be effectively cooled. At the same time, in this process, the abutting water bag 3 can abut the middle of the welding point between the second bamboo tube 11 and the membrane water-cooled wall, thereby playing a windproof role.

[0044] As a further embodiment of the present invention, a water pump 12 is fixedly connected to one side of the top of one end of the bottom plate 1, and the input end of the water pump 12 is connected to a water outlet pipe 19, and the end of the water outlet pipe 19 away from the water pump 12 is connected to the water tank 18, and the output end of the water pump 12 is connected to an input pipe 25, and the end of the input pipe 25 away from the water pump 12 is connected to the abutting water bag 3, and the side of the abutting water bag 3 away from the input pipe 25 is connected to an output pipe 24, and the end of the output pipe 24 away from the abutting water bag 3 is connected to a cooling water chamber 21, and a pressure valve is provided at the connection between the two, and the cooling water chamber 21 is provided inside the bottom plate 1 and one of the side plates 32, and the cooling water chamber 21 is located on the outside of the air outlet pipe 22, and the end of the cooling water chamber 21 away from the output pipe 24 is connected to the two abutting water bags 3.

[0047] In specific implementation, the water pressure valve is provided with a water pressure preset value. When the water pressure in the abutting water bag 3 and the collecting pipe 8 is higher than the water pressure preset value of the water pressure valve, the water pressure valve opens, otherwise the water pressure valve closes. 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.

[0048] It should be noted that the water pressure preset value is the same as the pressure preset value.

[0049] As a further embodiment of the present invention, photovoltaic panels 7 are fixedly connected on 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 panels 32 respectively. The vertical end of the return pipe 17 is embedded in the interior of the end plate 33, and an annular condenser 16 is embedded in the interior of 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 interior of the end plate 33.

[0051] 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, which is located on the side of the base plate 1 away from the door panel 2.

The current monitoring sensor 30 is connected in series with the welding gun 6. 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. The electric heating plate 26 is a resistance-type heating plate. The end of the external power supply away from the current monitoring sensor 30 is also directly connected to a return wire.

After receiving the first request information, the controller will generate a first control information, and then send the first control information to the dual-control switch 31. After receiving the first control information, the dual-control switch 31 will switch the circuit from contact 2 to contact 1, so that the electric heating plate 26 is connected in series to the circuit.

[0055] When the current in the circuit is lower than the minimum current preset value, the current monitoring sensor 30 will feedback the second request information to the controller. After receiving the second request information, the controller will generate second control information and then send the second control information to the double-control switch 31. After receiving the second control information, the double-control switch 31 will switch the circuit from contact one to contact two, so that the electric heating plate 26 is disconnected from the circuit, so that only the current monitoring sensor 30, the welding gun 6 and the double-control switch 31 are in the circuit.

[0056] It should be noted that if Figure 10 As shown in the figure, the letter "A" is the circuit symbol for the current monitoring sensor 30, representing current, the letter "U" represents AC voltage, and the letter "M" represents the welding gun 6. 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 conventional circuit diagrams, but in the present invention, it only represents the welding gun 6.

[0057] Working principle of the present invention:

[0058] When the present invention is in use, first, by opening the door panel 2, the technicians enter the interior of the device and close the door panel 2, and then move the device to the position where the membrane water-cooled wall needs to be welded. After moving the device to the position where the membrane water-cooled 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 making the abutting water bag 3 expand. After the abutting water bag 3 expands, the device is controlled to make the abutting water bag 3 contact with the membrane water-cooled wall. The abutting water bag 3 is soft in texture, so it will fit with the membrane water-cooled wall. The abutting water bag 3 fits on the membrane water-cooled wall, and the space welded in the middle of the device is windproof, which is beneficial to prevent the wind on both sides of the membrane water-cooled wall welding point from entering the space on the side opposite to each other of the two side panels. At the same time, the fit between the abutting water bag 3 and the membrane water-cooled wall can also provide windproof treatment for the second bamboo tube 11.

[0059] When welding, the device can protect the membrane water-cooled wall from wind and block the natural wind from the outside through two side plates 32 and one end plate 33. It should be noted that since the membrane water-cooled wall is large, the welding of the membrane water-cooled wall is usually completed outdoors, and if the old membrane water-cooled wall is to be repaired and welded, a lifting ladder is required to send technicians to high altitudes for welding operations.

[0060] After controlling the abutting water bag 3 to abut against the membrane water-cooled wall, the technician picks up the welding gun 6 to weld the membrane water-cooled wall. During the welding process, the welding gun 6 is protected from overcurrent by the current monitoring sensor 30. When the current inside the welding gun 6 is higher than the preset current value, the circuit is switched by the double-control switch 31, and the electric heating plate 26 is connected in series to the circuit. After the electric heating plate 26 is connected in series to the circuit, the overall voltage of the circuit will increase, thereby reducing the current of the circuit. The current is the ratio of voltage to resistance. 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 to the circuit, the current of the circuit can be reduced. On the one hand, the welding gun 6 can be protected from overcurrent. On the other hand, it can also help to avoid the occurrence of pores on the weld due to excessive current in the welding gun 6 during welding.

[0061] After the electric heating plate 26 is connected in series to the circuit, the electric heating plate 26 will also emit heat, which can heat the welding rods in the placement box 14, which is beneficial to drying the welding rods in the placement box 14. By drying the welding rods, it is beneficial to avoid the occurrence of pores in the welds of the membrane water-cooled wall welding due to moisture in the welding rods, further reducing the pores on the welds, which is beneficial to improving the quality of the welds.

[0062] In the process of welding the membrane water-cooled 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. In the process of horizontally welding the membrane water-cooled wall, the two abutting water bags 3 will respectively abut the unwelded part and the welded part of the membrane water-cooled wall. After the water pump 12 is turned on, it will drive the flow of water inside the abutting water bags 3. The water flow inside the abutting water bags 3 abutting the unwelded part can weld the unwelded part. Cooling, especially for welding work in summer, the membrane water-cooled wall is usually hot, and welding when the membrane water-cooled wall is hot is prone to excessive thermal stress after welding, affecting the subsequent service life. By abutting the membrane water-cooled wall with the abutting water bag 3, the internal water flow can cool the location where the membrane water-cooled wall needs to be welded, which is conducive to eliminating the thermal stress caused by the membrane water-cooled wall during the subsequent welding process, thereby increasing the service life of the membrane water-cooled wall and further ensuring the welding quality of the membrane water-cooled wall. Secondly, during the welding work in summer, the photovoltaic panel 7 can also play a role in shading the technicians, and the blast assembly can also increase the coolness of the technicians.

[0063] When technicians perform welding work, especially high-altitude work, the work usually lasts for a long time. Therefore, long-term welding work will cause the technicians to experience congested eyes and fatigue, and the welding arc will also cause the technicians' eyes to be burned by the ultraviolet rays it emits. By setting the welding mask 4, the ultraviolet rays emitted by the welding arc can be protected during the welding process, thereby improving the safety of the technicians. After the air pump 15 is turned on, air will be extracted from the inside of the welding mask 4 through the first bamboo tube 5, the fan-shaped groove 34 and the air vent 35. When the technicians perform welding work, it can drive the air flow around the mask, reduce the temperature of the technicians' faces through the flow of air, and have a certain cooling effect on the technicians, which is conducive to avoiding the occurrence of congested eyes of technicians due to long-term work.

[0064] After the gas is extracted by the air pump 15, it will enter the electromagnetic three-way valve 10 through the outlet pipe 22. First, the outlet pipe 22 is connected to the second bamboo tube 11 by controlling the electromagnetic three-way valve 10, and the air outlet end of the second bamboo tube 11 is directed toward the weld of the membrane water-cooled wall. At this time, the airflow discharged from the second bamboo tube 11 can effectively cool the weld. At the same time, the abutting water bag 3 located on the same side of the device as the second bamboo tube 11 can also cool the membrane water-cooled wall after welding, which is conducive to achieving rapid cooling of the weld and reducing the cooling time of the welding work.

[0065] 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 air bag 27, thereby causing the air bag 27 to expand. After the air bag 27 expands, it will lift the welding rod located in the placement box 14. Since the four sides of the air bag 27 are fixed, the center of the air bag 27 will rise, thereby lifting the welding rod, causing the welding rod to fluctuate, thereby turning the welding rod. When the air pressure in the air bag 27 is higher than the preset air pressure value of the air pressure valve, the air pressure valve opens, allowing the excess gas in the air bag 27 to enter the cavity 28 through the built-in air pipe 29, and then blown into the placement box 14. The flow of air is conducive to discharging the humid gas discharged from the welding rod after drying in the placement box 14.

[0066] After the water pump 12 is turned on, it draws water from the water tank 18 through the outlet pipe 19, and then delivers the water to the annular water bag 13 through the inlet 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 outlet pipe 24 and the cooling water chamber 21 can keep the annular water bag 13 in an expanded state. Through the provision of the annular water bag 13, when there is dust and impurities on the surface of the welding rod, the technician can pass the welding rod through the inner ring of the annular water bag 13, and the expanded annular water bag 13 can clean and cool the welding rod. After a period of welding, the technician's eyes may become congested. By picking up the annular water bag 13 and applying it to the eyes, the eyes can be cooled and 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.

[0067] 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 in the subsequent cooling work of the weld, and further accelerating the cooling of the weld.

[0068] 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 water pressure preset value of the water pressure valve, the water pressure valve opens, allowing the water in the abutting water bags 3 to flow back to the water tank 18 through the return pipe 17. In this process, the condenser 16 is turned on to allow the condenser 16 to cool the reflux water.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
