Description

Technical Field

[0001] The present invention belongs to the technical field of storage tank welding, and in particular relates to a welding device for installing a photothermal molten salt storage tank. Background Art

[0002] Molten salt tanks play an important role in solar thermal power stations and are the core of new energy storage solar thermal power stations. Their high heat storage capacity and high stability can not only enable solar thermal power stations to function in rainy weather, but also provide important support for solving the intermittent problems of new energy such as photovoltaic and wind power in the process of building new power systems. When installing molten salt tanks, welding is required to ensure the sealing of the tanks and prevent leakage during use of the tanks, which may cause environmental pollution.

[0003] A patent with publication number CN118513748B discloses a welding device for installing solar thermal molten salt storage tanks. This device, through a guiding positioning unit and a drive motor, can perform three-dimensional welding between the tank and the pipeline. By fitting a deformable ring and an elastic ring to the surface of the tank, a deformed track with the same trajectory is formed, which is then energized and solidified. The drive motor is then activated, and with the cooperation of a spring telescopic column, the welding gun in the adjustment block can be assisted to complete precise welding operations. Furthermore, when performing planar circumferential welding between tanks, a guide rail is formed after the variable rope loop is energized and solidified, onto which a hoop is fitted. The roller and motor-assisted bracket rotate along the tank surface to complete the circumferential welding. This design accommodates tanks of different sizes and reduces costs.

[0004] There are still some problems in the actual application of the above scheme. Usually, the top cover of the photothermal molten salt storage tank is docked with the photothermal molten salt storage tank, and then the operator controls the laser welder to move in a circular shape around the installation docking point of the photothermal molten salt storage tank, and the laser welder is used to weld the installation docking point. However, in the process of controlling the laser welder to move in a circular shape around the photothermal molten salt storage tank, if the laser welder shakes slightly, it will cause discontinuity of the weld at the installation docking point of the photothermal molten salt storage tank, and the discontinuity of the weld will easily lead to a reduction in the sealing of the photothermal molten salt storage tank. When welding the installation docking point of the photothermal molten salt storage tank, if the gap at the installation docking point is large, it will also cause small channels to form in the gap area, resulting in leakage problems at the welding point under high temperature and high pressure environment in the later stage.

[0005] To this end, the present invention provides a welding device for installing a photothermal molten salt storage tank. Summary of the Invention

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] Example 1: Figures 1 to 8 As shown, a welding device for installing a photothermal molten salt storage tank according to an embodiment of the present invention includes a base 1, a bracket 2 is installed on the upper end surface of the base 1, the upper end cavity of the bracket 2 is used to place the photothermal molten salt storage tank body 3, and a drive calibration component 4 is provided inside the bracket 2;

[0040] The drive calibration assembly 4 includes two bidirectional telescopic rods 41 rotatably connected to the interior of the upper end of the bracket 2, and the piston rod ends of the two bidirectional telescopic rods 41 are installed with mounting sleeves 42;

[0041] A rubber toothed roller 43 is fixed to the outside of the mounting sleeve 42. The rubber toothed roller 43 is used to support the solar thermal molten salt storage tank body 3 and can drive the solar thermal molten salt storage tank body 3 to rotate in a circular shape.

[0042] An L-shaped clamping plate 46 is installed at one end of the rubber toothed roller 43, and the L-shaped clamping plate 46 is used to abut and clamp the two ends of the solar thermal molten salt storage tank body 3, which can make the installation joint of the solar thermal molten salt storage tank body 3 tighter and ensure welding accuracy;

[0043] A through groove 13 is provided in the middle of the upper end surface of the base 1, and a slider 8 is slidably connected to the inner cavity of the through groove 13. A servo push rod 12 is installed inside the slider 8, and a laser welder 10 is installed at the piston rod end of the servo push rod 12 for welding the installation joint of the photothermal molten salt storage tank body 3.

[0044] Specifically, in the prior art, a crane is usually used to lift the top cover of the photothermal molten salt storage tank, and then the top cover is controlled to dock with the photothermal molten salt storage tank. After the docking is completed, the operator controls the laser welder 10 to move in a circular shape around the installation docking point of the photothermal molten salt storage tank, and the laser welder 10 is used to weld the installation docking point. However, in the process of controlling the laser welder 10 to move in a circular shape around the photothermal molten salt storage tank, if the laser welder 10 vibrates slightly, it will cause discontinuity of the weld at the installation docking point of the photothermal molten salt storage tank, and the discontinuity of the weld will easily lead to reduced sealing of the photothermal molten salt storage tank. When welding the installation docking point of the photothermal molten salt storage tank, if the gap at the installation docking point is large, it will also cause micro-channels to form in the gap area, resulting in leakage problems at the welding point in a high temperature and high pressure environment in the later stage.

[0045] When the present invention is installing and manufacturing the photothermal molten salt storage tank body 3, the photothermal molten salt storage tank body 3 is placed on the bracket 2, and the two-way telescopic rod 41 is started at the same time to drive the installation sleeve 42 to move away from each other, and the installation sleeve 42 drives the rubber toothed roller 43 to move synchronously, and then the rubber toothed roller 43 drives the L-shaped clamping plate 46 to move synchronously, so that the L-shaped clamping plate 46 is used to abut the two ends of the photothermal molten salt storage tank body 3 to form a clamping effect, and as the two-way telescopic rod 41 continues to operate, the L-shaped clamping plate 46 is driven to abut the two ends of the photothermal molten salt storage tank body 3, and the photothermal molten salt storage tank body 3 is pushed to move closer to each other, thereby making the installation joint of the photothermal molten salt storage tank body 3 tighter. , and then simultaneously drive the bidirectional telescopic rod 41 to rotate inside the bracket 2, and make the bidirectional telescopic rod 41 drive the mounting sleeve 42 to rotate, and at the same time the mounting sleeve 42 drives the rubber tooth roller 43 to rotate, and then the rubber tooth roller 43 drives the photothermal molten salt storage tank body 3 to rotate. During the rotation of the photothermal molten salt storage tank body 3, the servo push rod 12 is started to drive the laser welder 10 to move upward for distance adjustment, and at the same time drive the slider 8 to slide and adjust the position in the inner cavity of the through groove 13, so that the laser welder 10 is moved to the installation docking position of the photothermal molten salt storage tank body 3, and then the laser welder 10 is started and cooperated with the rotating photothermal molten salt storage tank body 3 to weld the installation docking position, thereby solving the above problem.

[0046] like Figure 2 、 Figure 3 and Figure 8 As shown, a rotation groove 44 is opened inside one end of the rubber toothed roller 43, and an L-shaped clamping plate 46 is rotatably connected to the inner cavity of the rotation groove 44. The L-shaped clamping plate 46 is located outside the inner cavity of the rotation groove 44 and is fixed with a ratchet 45. The clockwise rotation of the rubber toothed roller 43 cannot drive the L-shaped clamping plate 46 to rotate.

[0047] like Figure 2 、 Figure 3 and Figure 8As shown, a plurality of balls 47 are rotatably connected to one side of the L-shaped clamping plate 46, and after the plurality of balls 47 abut and clamp the two ends of the photothermal molten salt storage tank body 3, they can still drive the photothermal molten salt storage tank body 3 to rotate in the inner cavity of the bracket 2.

[0048] Specifically, after the photothermal molten salt storage tank body 3 is installed in the inner cavity of the bracket 2, the rubber toothed rollers 43 are driven to move closer to each other, and the rubber toothed rollers 43 drive the ratchet 45 to move, and at the same time the ratchet 45 drives the L-shaped clamping plate 46 to move synchronously, so that the L-shaped clamping plate 46 uses the ball 47 to abut against the two ends of the photothermal molten salt storage tank body 3 to form a clamp. As the rubber toothed roller 43 continues to move, the ratchet 45 is driven to move, and the L-shaped clamping plate 46 is driven to abut against and push the two ends of the photothermal molten salt storage tank body 3 closer to each other, thereby reducing the gap between the installation and docking of the photothermal molten salt storage tank body 3, so as to improve the welding accuracy. In addition, the arrangement of multiple balls 47 on one side of the L-shaped clamping plate 46 can After the photothermal molten salt storage tank body 3 is abutted and clamped, the rubber tooth roller 43 can also drive the photothermal molten salt storage tank body 3 to rotate, and cooperate with the laser welder 10 to weld the photothermal molten salt storage tank body 3 at the same time, thereby solving the problem that the existing photothermal molten salt storage tank installation welding device is inconvenient to clamp the photothermal molten salt storage tank installation joint when welding at the photothermal molten salt storage tank installation joint, so as to ensure that the gap at the photothermal molten salt storage tank installation joint is reduced, resulting in the gap at the photothermal molten salt storage tank joint being too large when welding, affecting the welding accuracy, causing the photothermal molten salt storage tank to be prone to leakage due to overheating during the later use of the photothermal molten salt storage tank.

[0049] like Figures 1 to 4 and Figure 8 As shown, the outside of the bidirectional telescopic rod 41 is fixedly connected to the first sprocket 11, the outside of the first sprocket 11 is connected to the chain 6 for transmission, and the inner cavity of one end of the chain 6 is connected to the second sprocket 14 for transmission, and a servo motor 5 is installed at the bottom of the inner cavity of the bracket 2, and the output shaft end of the servo motor 5 is fixedly connected to the second sprocket 14.

[0050] like Figures 1 to 4 and Figure 8 As shown, slide rails 7 are provided on both walls of the inner cavity of the through groove 13, and the slider 8 is slidably connected in the inner cavity of the slide rail 7. The slider 8 is driven to move by the slide rail 7 to drive the laser welder 10 to adjust the position of welding according to the installation docking point of the photothermal molten salt storage tank body 3.

[0051] Specifically, after the photothermal molten salt storage tank body 3 is installed and docked in the inner cavity of the bracket 2, the slider 8 is driven to move in the inner cavity of the slide rail 7, and the slider 8 drives the servo push rod 12 and the laser welder 10 to move synchronously, so as to adjust the position to be welded according to the installation and docking position of the photothermal molten salt storage tank body 3. At the same time, the servo push rod 12 is used to drive the laser welder 10 to move upward, and then the distance between the laser welder 10 and the photothermal molten salt storage tank body 3 is adjusted. Then, the servo motor 5 is started to drive the second sprocket 14 to rotate, and the second sprocket 14 drives the chain 6 to rotate, and then drives the first sprocket 11 to rotate. When the first sprocket 11 rotates, it will drive the bidirectional telescopic rod 41 to rotate. At the same time, the two-way telescopic rod 41 drives the installation sleeve 42 to rotate, and drives the rubber tooth roller 43 to rotate, thereby driving the photothermal molten salt storage tank body 3 to rotate at a uniform speed. During the rotation of the photothermal molten salt storage tank body 3, the laser welder 10 is started to weld around the installation joint of the photothermal molten salt storage tank body 3, thereby solving the problem that the existing photothermal molten salt storage tank installation welding device usually controls the laser welder 10 to rotate in a circular shape around the photothermal molten salt storage tank for welding. If the laser welder 10 shakes during the moving welding around the photothermal molten salt storage tank, it is easy to cause the laser welding head and the joint of the photothermal molten salt storage tank to deviate, thereby affecting the welding quality and accuracy, and causing the photothermal molten salt storage tank to leak easily.

[0052] Example 2: Figure 2 、 Figure 5 and Figure 6 As shown, a welding auxiliary component 9 is provided on the outside of the laser welder 10, and the welding auxiliary component 9 includes an H-shaped mounting frame 91 installed on the outside of the laser welder 10. The inner cavity of the H-shaped mounting frame 91 is rotatably connected to two T-shaped rotating rods 92, and one of the T-shaped rotating rods 92 is rotatably connected to the outside of a grinding roller 93 for grinding the welding slag at the welding completion point of the photothermal molten salt storage tank body 3.

[0053] Specifically, when the laser welder 10 is driven close to the photothermal molten salt storage tank body 3 to adjust the focal length, the laser welder 10 drives the H-shaped mounting frame 91 to move synchronously, and at the same time, the H-shaped mounting frame 91 drives the T-shaped rotating rod 92 to move upward, and the T-shaped rotating rod 92 drives the grinding roller 93 to move synchronously, and at the same time, the grinding roller 93 is in contact with the surface of the photothermal molten salt storage tank body 3. As the laser welder 10 continues to move upward, the grinding roller 93 will be in contact with the surface of the photothermal molten salt storage tank body 3 and move to one side, and then the photothermal molten salt storage tank body 3 is driven to rotate at a uniform speed to cooperate with the laser welding. When the device 10 is welded, the grinding roller 93 is used to grind and polish the welding completion position of the photothermal molten salt storage tank body 3, so as to remove the welding slag at the welding position of the photothermal molten salt storage tank body 3, and then better observe whether there is any welding leakage at the joint of the photothermal molten salt storage tank body 3, thereby solving the problem that when the existing photothermal molten salt storage tank welding device is used to weld and fix the installation joint of the photothermal molten salt storage tank, if the welding slag generated at the welding completion position of the photothermal molten salt storage tank is not ground and polished away, it is difficult to better observe whether there is any welding leakage at the joint of the photothermal molten salt storage tank.

[0054] like Figure 2 、 Figures 5 to 7 As shown, one end of another T-shaped rotating rod 92 is externally rotatably connected to a U-shaped rotating frame 15, a second torsion spring 16 is fixed to the bottom of the inner cavity of the U-shaped rotating frame 15, one end of the second torsion spring 16 is fixed to the T-shaped rotating rod 92, and a scraper 97 is installed at one end of the U-shaped rotating frame 15, and the dirt such as mud on the outer surface of the solar thermal molten salt storage tank body 3 is removed by the scraper 97.

[0055] like Figure 2 、 Figures 5 to 7 As shown, the scraper 97 is arranged in a T shape, and grinding particles are provided on both sides of the T-shaped protrusion of the scraper 97, which are used to grind and polish the installation joint of the photothermal molten salt storage tank body 3.

[0056] Specifically, before welding the installation joint of the photothermal molten salt storage tank body 3, the H-shaped mounting frame 91 is driven to move upward, and the H-shaped mounting frame 91 drives the T-shaped rotating rod 92 to move upward, and at the same time, the T-shaped rotating rod 92 drives the U-shaped rotating frame 15 to move synchronously, so that the U-shaped rotating frame 15 drives the scraper 97 to fit the surface of the photothermal molten salt storage tank body 3. After the scraper 97 fits the surface of the photothermal molten salt storage tank body 3, the U-shaped rotating frame 15 is rotated by twisting the second torsion spring 16, and The U-shaped rotating frame 15 drives the scraper 97 to always fit with the surface of the photothermal molten salt storage tank body 3 at an inward inclination angle of thirty to sixty degrees, and the scraper 97 is set in a T shape. After the scraper 97 fits with the surface of the photothermal molten salt storage tank body 3, the blade at the T-shaped protrusion of the scraper 97 will be inserted into the installation docking part of the photothermal molten salt storage tank body 3, and the T-shaped protrusion of the scraper 97 is electroplated on both sides to fix the abrasive on both sides of the T-shaped protrusion of the scraper 97 by electroplating to form a grinding layer, thereby driving the scraper 97 to form a grinding layer. During the uniform rotation of the photothermal molten salt storage tank body 3, the dirt such as the soil on the surface of the photothermal molten salt storage tank body 3 is removed by using the scraper 97 to avoid affecting the accuracy and quality of subsequent laser welding. At the same time, the T-shaped protrusion of the scraper 97 is used to grind the joint of the photothermal molten salt storage tank body 3, and the iron filings in the joint of the photothermal molten salt storage tank body 3 are scraped off to avoid the formation of pores or slag in the welding due to garbage such as iron filings in the joint of the photothermal molten salt storage tank body 3 after welding, thereby solving the problem. The existing welding device for installing the solar thermal molten salt storage tank is inconvenient to grind the joints of the solar thermal molten salt storage tank during welding and installation, resulting in problems such as porosity and slag inclusions in the joints of the solar thermal molten salt storage tank due to iron filings and other garbage after welding. Moreover, if the dirt and other dirt on the surface of the solar thermal molten salt storage tank is not removed, the area covered with dirt will cause arc blow, causing the welding current and voltage to fluctuate, affecting the stability of the welding process, resulting in poor weld formation, and defects such as undercuts and weld bumps.

[0057] like Figure 2 、 Figures 5 to 7 As shown, grooves 94 are formed on both walls of the inner cavity of the H-shaped mounting frame 91 , a first torsion spring 96 is fixedly connected to the inner cavity of the groove 94 , a fixing plate 95 is fixedly connected to the outside of the T-shaped rotating rod 92 , and one end of the first torsion spring 96 is fixedly connected to the fixing plate 95 .

[0058] Specifically, before welding the installation joint of the photothermal molten salt storage tank body 3, the first torsion spring 96 is used to twist the fixed plate 95 to rotate, and the fixed plate 95 drives the T-shaped rotating rod 92 to rotate, and then the T-shaped rotating rod 92 drives the grinding roller 93 and the scraper 97 to fit more closely with the surface of the photothermal molten salt storage tank body 3, so that the grinding roller 93 and the scraper 97 can better grind the surface of the photothermal molten salt storage tank body 3 and remove dirt such as mud, thereby improving the welding accuracy and quality.

[0059] like Figure 2 、 Figure 3 and Figure 8 As shown, an elastic plug-in 48 is provided on the inner wall of the rotating groove 44 , and the elastic plug-in 48 is plugged into the ratchet 45 . When the rubber tooth roller 43 rotates counterclockwise, the elastic plug-in 48 can drive the ratchet 45 to rotate.

[0060] Specifically, by driving the rubber toothed roller 43 to rotate counterclockwise, the rubber toothed roller 43 drives the elastic plug-in 48 to rotate, and at the same time the elastic plug-in 48 drives the ratchet 45 to rotate, and drives the L-shaped splint 46 to rotate, and then rotates the L-shaped splint 46 to the two ends of the photothermal molten salt storage tank body 3. The rubber toothed roller 43 is driven to move closer to each other, and the rubber toothed roller 43 drives the L-shaped splint 46 to abut and clamp the two ends of the photothermal molten salt storage tank body 3, so as to ensure that the installation and docking of the photothermal molten salt storage tank body 3 is tighter, thereby improving the installation and welding quality of the photothermal molten salt storage tank.

[0061] The working principle is that after the photothermal molten salt storage tank body 3 is installed in the inner cavity of the bracket 2, the rubber toothed rollers 43 are driven to move close to each other, and the rubber toothed rollers 43 drive the ratchet 45 to move, and at the same time the ratchet 45 drives the L-shaped clamping plate 46 to move synchronously, so that the L-shaped clamping plate 46 uses the ball 47 to abut against the two ends of the photothermal molten salt storage tank body 3 to form a clamp. As the rubber toothed roller 43 continues to move, the ratchet 45 is driven to move, and at the same time, the L-shaped clamping plate 46 is driven to abut against and push the two ends of the photothermal molten salt storage tank body 3 close to each other, thereby reducing the gap between the installation and docking of the photothermal molten salt storage tank body 3, so as to improve the welding accuracy. Moreover, the arrangement of multiple balls 47 on one side of the L-shaped clamping plate 46 can enable the rubber toothed roller 43 to drive the photothermal molten salt storage tank body 3 to rotate after the photothermal molten salt storage tank body 3 is abutted and clamped, and at the same time cooperate with the laser welder 10 to weld the docking part of the photothermal molten salt storage tank body 3.

[0062] When the laser welder 10 is driven to approach the photothermal molten salt storage tank body 3 to adjust the focal length, the laser welder 10 drives the H-shaped mounting frame 91 to move synchronously, and at the same time, the H-shaped mounting frame 91 drives the T-shaped rotating rod 92 to move upward, and the T-shaped rotating rod 92 drives the grinding roller 93 to move synchronously, and at the same time, the grinding roller 93 is in contact with the surface of the photothermal molten salt storage tank body 3. As the laser welder 10 continues to move upward, the grinding roller 93 will be in contact with the surface of the photothermal molten salt storage tank body 3 and move to one side. Then, when the photothermal molten salt storage tank body 3 is driven to rotate at a uniform speed to cooperate with the laser welder 10 for welding, the grinding roller 93 is used to grind and polish the welded part of the photothermal molten salt storage tank body 3, so as to remove the welding slag at the welding part of the photothermal molten salt storage tank body 3, and then better observe whether there is any welding leakage at the joint of the photothermal molten salt storage tank body 3.

[0063] Before welding the installation joint of the solar thermal molten salt storage tank body 3, the H-shaped mounting frame 91 is driven to move upward, and the H-shaped mounting frame 91 drives the T-shaped rotating rod 92 to move upward. At the same time, the T-shaped rotating rod 92 drives the U-shaped rotating frame 15 to move synchronously, so that the U-shaped rotating frame 15 drives the scraper 97 to fit the surface of the solar thermal molten salt storage tank body 3. After the scraper 97 fits the surface of the solar thermal molten salt storage tank body 3, the second torsion spring 16 is used to twist the U-shaped rotating frame 15 to rotate, and the U-shaped rotating frame 15 drives the scraper 97 to always fit the surface of the solar thermal molten salt storage tank body 3 at an inward inclination angle of thirty to sixty degrees, and the scraper 97 is set in a T shape. After the scraper 97 fits the surface of the solar thermal molten salt storage tank body 3, the T of the scraper 97 The blade at the raised part of the shape will be inserted into the installation joint of the photothermal molten salt storage tank body 3, and the abrasive is fixed on both sides of the T-shaped protrusion of the scraper 97 by electroplating to form a grinding layer. Then, in the process of driving the photothermal molten salt storage tank body 3 to rotate at a uniform speed, the scraper 97 is used to remove dirt such as mud on the surface of the photothermal molten salt storage tank body 3 to avoid affecting the accuracy and quality of subsequent laser welding. At the same time, the T-shaped protrusion of the scraper 97 is used to grind the joint of the photothermal molten salt storage tank body 3, and the iron filings in the joint of the photothermal molten salt storage tank body 3 are scraped off to avoid the formation of air holes or slag inclusions in the welding due to garbage such as iron filings in the joint of the photothermal molten salt storage tank body 3 after welding.
