Technical Field

[0002] Solar photovoltaic brackets are structural components used to support solar photovoltaic modules in solar photovoltaic power generation systems. The primary function of photovoltaic brackets is to firmly support photovoltaic modules. Solar photovoltaic modules are usually fragile and require stable support structures to maintain their stable position under various environmental conditions. For example, in outdoor environments, they must withstand the test of natural factors such as wind, snow, and rain. If there is no reliable bracket, photovoltaic modules may shift, deform, or even be damaged, thus affecting the normal operation of the photovoltaic power generation system. The structure is simple and the cost is low. Its installation angle is generally fixed after installation, and is usually pre-designed according to the local latitude and the best sunshine angle.

The filter screen is provided on the top of the connecting plate to block the welding slag entering the main body through the suction force of the air suction machine, so that the exhaust gas is sucked into the connecting pipe through the filter screen. At the same time, the exhaust gas is continuously moved in the connecting pipe by the continuous operation of the air suction machine, so that the exhaust gas enters the filter tube, so that the particles in the exhaust gas are adsorbed by the activated carbon box, and the filtered exhaust gas is discharged through the air suction machine. At the same time, when the air suction machine is inhaling, the connecting frame slides on the sliding rod, and at the same time, the third spring is pulled to move, so that the connecting frame drives the scraper to clean and scratch the inner side of the filter tube, so as to avoid that when the exhaust gas is continuously sucked and filtered, the exhaust gas passes through the filter tube for a long time, and a large amount of exhaust gas impurities will remain on the inner wall of the filter tube, causing corrosion to the inner wall of the filter tube.

At the same time, when the suction machine stops suction, the welding slag enters the main body together with the exhaust gas through the suction force of the suction machine, and a small amount of welding slag will be stuck in the mesh of the mesh plate, thereby causing the mesh of the mesh plate to be blocked. When the suction machine stops suction, the grid is stretched by the reset of the first spring, so that the grid drives the extrusion mechanism to move toward the mesh plate, so that the extrusion mechanism ejects the impurities stuck in the mesh of the mesh plate.

If it is not cleaned for a long time, a large amount of impurities will accumulate on the inner side of the mesh plate, causing the mesh diameter of the mesh plate to become smaller, making it easier for welding slag to be blocked when passing through. At the same time, when the extrusion block squeezes and dredges the mesh of the mesh plate, when the impurities are stuck tightly on the inner side of the mesh of the mesh plate, the extrusion force between the extrusion block and the impurities stuck in the mesh is greater than the tensile force of the second spring, so that the extrusion block is moved in the notch through the slide bar and the slider, thereby avoiding excessive extrusion force between the extrusion block and the impurities stuck in the mesh, which will cause extrusion damage to the extrusion block, and also avoiding excessive extrusion force with the impurities stuck between the mesh, which will cause friction damage to the aperture of the mesh, causing the aperture of the mesh to expand; Preferably, the collecting component comprises an electric hydraulic cylinder and a collecting barrel, the electric hydraulic cylinder is fixedly connected to the side of the main body, the inner side of the main body is slidably connected with an auxiliary rod, one end of the auxiliary rod away from the inner side of the main body is fixedly connected to the pushing block, the output end of the electric hydraulic cylinder is fixedly connected to a connecting rod, the other end of the connecting rod is fixedly connected to the pushing block, the bottom of the pushing block is rotatably connected to a rotating mechanism, the side of the collecting barrel is fixedly connected to the main body, and a discharge port is provided on the side of the main body close to the collecting barrel; when impurities enter the main body through the anti-blocking component, a filter screen is provided on the connecting plate, so that the filter screen separates the impurities and exhaust gas entering the inner side of the main body, thereby When welding slag remains on the connecting plate and the welding slag accumulated on the connecting plate needs to be cleaned, the electric hydraulic cylinder is opened, and the output end of the electric hydraulic cylinder drives the pushing block to move on the connecting plate through the connecting rod, so that the pushing block pushes the welding slag impurities accumulated on the connecting plate, thereby pushing the welding slag dropped on the connecting plate into the collecting cylinder through the discharge port, and cleaning the welding slag accumulated on the connecting plate, thereby avoiding a large amount of welding slag from gathering around the filter screen and interfering with the normal suction work of the air suction machine.

At the same time, grabbing rods are provided at both ends of the rotating rod, so that when the rotating rod rotates to clean the filter, the grabbing rods can grab the floating flocculent dust, thereby preventing a large amount of flocculent dust from being entangled on the brush when the filter is cleaning, thereby interfering with the normal cleaning of the filter.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention provides a filter component, turns on the air sucker, and uses the suction force generated by the air sucker when it is working to absorb the waste gas generated during the welding of the solar photovoltaic bracket, so that the waste gas and welding slag generated by the welding enter the inner side of the main body through the anti-blocking component, and at the same time, a filter is provided on the top of the connecting plate to block the welding slag entering the main body through the suction force of the air sucker, so that the waste gas is sucked into the connecting pipe through the filter, and at the same time, the waste gas is continuously moved in the connecting pipe through the continuous operation of the air sucker, so that the waste gas enters the filter pipe, so that the particles in the waste gas are adsorbed by the activated carbon box, and the filtered waste gas is discharged through the air sucker.

[0006] 2. The present invention provides an extrusion mechanism. When the air suction machine stops the air suction work, the grid frame is stretched by the reset of the first spring, so that the grid frame drives the extrusion rod to move toward the mesh plate, so that the extrusion rod drives the extrusion block to eject the impurities blocked in the mesh holes of the mesh plate. At the same time, a circle of round edges is provided at the bottom of the extrusion block, so that when the extrusion block ejects the impurities blocked in the mesh holes of the mesh plate, the round edges at the bottom of the extrusion block can clean and contact the inner side of the mesh holes of the mesh plate, thereby avoiding impurities remaining on the inner side of the mesh holes of the mesh plate. If it is not cleaned for a long time, a large amount of impurities will accumulate on the inner side of the mesh holes. This causes the mesh aperture of the mesh plate to become smaller, making it easier for welding slag to get clogged when passing through. At the same time, when the extrusion block squeezes and clears the mesh aperture of the mesh plate, when impurities are stuck tightly on the inside of the mesh aperture of the mesh plate, the extrusion force between the extrusion block and the impurities stuck in the mesh aperture is greater than the tensile force of the second spring, thereby allowing the extrusion block to move in the slot through the slide rod and the slider, thereby avoiding excessive extrusion force between the extrusion block and the impurities stuck in the mesh aperture, which would cause extrusion damage to the extrusion block, and also avoiding excessive extrusion force between the impurities stuck between the mesh apertures, which would cause friction damage to the aperture of the mesh aperture, causing the mesh aperture to expand.

[0007] 3. The present invention provides a collecting component. When impurities enter the main body through the anti-blocking component, a filter is provided on the connecting plate, so that the filter separates the impurities and exhaust gas entering the inner side of the main body, so that welding slag remains on the connecting plate. When the welding slag accumulated on the connecting plate needs to be cleaned, the electric hydraulic cylinder is opened, and the output end of the electric hydraulic cylinder drives the pushing block to move on the connecting plate through the connecting rod, so that the pushing block pushes the welding slag impurities accumulated on the connecting plate, thereby pushing the welding slag dropped on the connecting plate into the collecting cylinder through the discharge port, and cleaning the welding slag accumulated on the connecting plate, thereby avoiding a large amount of welding slag from gathering around the filter and interfering with the normal suction work of the air suction machine. At the same time, when the output end of the electric hydraulic cylinder drives the pushing block to move, the pushing block drives the rotating mechanism through the filter, so that the rotating mechanism cleans the top of the filter.

[0008] 4. The present invention provides a rotating mechanism. When the pushing block drives the rotating rod to reach the top of the filter, the suction force generated by the suction machine when working makes the rotating rod drive the brush to rotate on the filter, so that the brush cleans the top of the filter, thereby avoiding that when the filter is filtering, a large amount of welding slag and dust that follows the welding slag into the inner cavity of the main body will be accumulated on the top of the filter, thereby clogging the filter. At the same time, by providing grabbing rods at both ends of the rotating rod, the grabbing rods can grab the floating flocculent dust when the rotating rod rotates to clean the filter, thereby avoiding that when the filter is cleaning, a large amount of flocculent dust will be entangled on the brush, thereby interfering with the normal cleaning of the filter.

The air suction machine 54 is fixedly connected to the side of the main body 1. The inner side of the filter tube 51 is fixedly connected to the activated carbon box 53. Both sides of the inner cavity of the connecting tube 52 are fixedly connected. A bracket 56 is connected, a sliding rod 55 is fixedly connected to the side of the bracket 56, a third spring 57 is fixedly connected to the side of the bracket 56 close to the sliding rod 55, a connecting frame 58 is fixedly connected to the end of the third spring 57 away from the bracket 56, and scrapers 59 are fixedly connected to both sides of the connecting frame 58, and the side of the scraper 59 away from the connecting frame 58 is in contact with the inner side of the connecting pipe 52; by turning on the suction machine 54, the suction force generated by the suction machine 54 when working can absorb the waste gas generated during the welding of the solar photovoltaic bracket, so that the waste gas and the welding slag can pass through the anti-blocking component 6 The exhaust gas enters the inner side of the main body 1, and a filter screen 510 is arranged on the top of the connecting plate 511 to block the welding slag entering the main body 1 through the suction force of the aspirator 54, so that the exhaust gas is sucked into the connecting pipe 52 through the filter screen 510. At the same time, the exhaust gas continues to move in the connecting pipe 52 through the continuous operation of the aspirator 54, so that the exhaust gas enters the filter pipe 51, so that the particles in the exhaust gas are adsorbed by the activated carbon box 53, and the filtered exhaust gas is discharged through the aspirator 54. At the same time, when the aspirator 54 is in the suction work, the connecting frame 5 8 slides on the sliding rod 55, and at the same time pulls the third spring 57 to move, so that the connecting frame 58 drives the scraper 59 to clean and scrape the inner side of the filter tube 51, thereby preventing the waste gas from passing through the filter tube 51 for a long time when the waste gas is continuously sucked and filtered, and a large amount of waste gas impurities will remain on the inner wall of the filter tube 51, causing corrosion to the inner wall of the filter tube 51. At the same time, when the air suction machine 54 stops working, the connecting frame 58 is resetting and stretching through the third spring 57, so that the connecting frame 58 drives the scraper 59 to clean and scrape the inner wall of the filter tube 51; Embodiment 2, use Figure 5 Figure 6 A welding device for a solar photovoltaic bracket of the present invention is described as follows; like Figure 5-Figure 6 It is shown that a welding device for a solar photovoltaic bracket of the present invention is based on the first embodiment; The anti-blocking component 6 includes a mesh plate 61, the side of the mesh plate 61 is fixedly connected to the inner side of the top plate 2, the bottom of the mesh plate 61 is slidably connected to a connecting shaft 62, the bottom of the connecting shaft 62 is fixedly connected to a grid frame 63, a first spring 64 is sleeved on the connecting shaft 62, the top of the first spring 64 is fixedly connected to the bottom plate of the mesh plate 61, the bottom of the first spring 64 is fixedly connected to the top of the grid frame 63, and the top of the grid frame 63 is fixedly connected to an extrusion mechanism 65; when the suction machine 54 performs the suction work, the waste gas and waste chips generated during the welding work are sucked into the inner side of the main body 1 through the mesh plate 61, and at the same time, due to the suction force of the suction machine 54, the The grid frame 63 moves downward through the connecting shaft 62, so that the grid frame 63 drives the extrusion mechanism 65 to move downward together. At the same time, when the suction machine 54 stops suction, the welding slag follows the exhaust gas into the main body 1 through the suction of the suction machine 54, and a small amount of welding slag will be stuck in the mesh of the mesh plate 61, thereby causing the mesh of the mesh plate 61 to be blocked. When the suction machine 54 stops suction, the grid frame 63 is stretched by the reset of the first spring 64, so that the grid frame 63 drives the extrusion mechanism 65 to move toward the mesh plate 61, so that the extrusion mechanism 65 ejects the impurities stuck in the mesh of the mesh plate 61. The extrusion mechanism 65 includes an extrusion shaft 651, a notch 652 is provided on the side of the extrusion shaft 651, a slider 653 is slidably connected to the inner side of the notch 652, a slide bar 654 is fixedly connected to the side of the slide bar 653, the side of the slide bar 654 is slidably connected to the inner side of the extrusion shaft 651, an end of the slide bar 654 away from the slide bar 653 is fixedly connected to an extrusion block 655, a second spring 656 is sleeved on the slide bar 654, the top of the second spring 656 is fixedly connected to the extrusion block 655, and the second The bottom of the spring 656 is fixedly connected to the top of the extrusion shaft 651; when the suction machine 54 stops the suction work, the grid 63 is stretched by the reset of the first spring 64, so that the grid 63 drives the extrusion rod to move toward the mesh plate 61, so that the extrusion rod drives the extrusion block 655 to eject the impurities blocked in the mesh of the mesh plate 61.

Example 3, using Figure 7-Figure 8 A welding device for a solar photovoltaic bracket of the present invention is described as follows; like Figure 7-Figure 8 It is shown that a welding device for a solar photovoltaic bracket of the present invention is based on the first embodiment; The collecting component 7 includes an electric hydraulic cylinder 71 and a collecting barrel 75. The electric hydraulic cylinder 71 is fixedly connected to the side of the main body 1. An auxiliary rod 72 is slidably connected to the inner side of the main body 1. The end of the auxiliary rod 72 away from the inner side of the main body 1 is fixedly connected to a pushing block 76. The output end of the electric hydraulic cylinder 71 is fixedly connected to a connecting rod 73. The other end of the connecting rod 73 is fixedly connected to a pushing block 76. The bottom of the pushing block 76 is rotatably connected to a rotating mechanism 77. The side of the collecting barrel 75 is fixedly connected to the main body 1. A discharge port 74 is provided on the side of the main body 1 close to the collecting barrel 75. When impurities enter the main body 1 through the anti-blocking component 6, a filter screen 510 is provided on the connecting plate 511, so that the filter screen 510 separates the impurities and waste gas entering the inner side of the main body 1, so that welding slag remains on the connecting plate 511. At the same time, when it is necessary to clean the welding slag accumulated on the connecting plate 511, the electric hydraulic cylinder 71 is opened, and the output end of the electric hydraulic cylinder 71 drives the pushing block 76 to move on the connecting plate 511 through the connecting rod 73, so that the pushing block 76 pushes the welding slag impurities accumulated on the connecting plate 511, so that the welding slag dropped on the connecting plate 511 is pushed into the collecting cylinder 75 through the discharge port 74, and the welding slag accumulated on the connecting plate 511 is cleaned, so as to avoid a large amount of welding slag from gathering around the filter screen 510 and interfering with the normal suction work of the suction machine 54. At the same time, when the output end of the electric hydraulic cylinder 71 drives the pushing block 76 to move, so that the pushing block 76 drives the rotating mechanism 77 to pass through the filter screen 510, the rotating mechanism 77 cleans the top of the filter screen 510; The rotating mechanism 77 includes a rotating rod 771, the top of which is rotatably connected to the bottom of the pushing block 76, a brush 772 is fixedly connected to the bottom of the rotating rod 771, the bottom of the brush 772 is in contact with the top of the connecting plate 511, and rotating grooves 773 are provided on both sides of the rotating rod 771, and a grabbing rod 774 is rotatably connected to the inner side of the rotating groove 773, and grabbing grooves 775 are provided on both sides of the grabbing rod 774; when the pushing block 76 drives the rotating rod 771 to reach the top of the filter screen 510, the suction force generated by the suction machine 54 when working makes the rotating rod 771 drive the brush 772 to rotate on the filter screen 510, so that the brush 772 The brush 772 cleans the top of the filter 510, thereby preventing a large amount of welding slag and dust that follows the welding slag into the inner cavity of the main body 1 from accumulating on the top of the filter 510 when the filter 510 is filtering, thereby clogging the filter 510. At the same time, by providing grabbing rods 774 at both ends of the rotating rod 771, the grabbing rods 774 can grab the floating flocculent dust when the rotating rod 771 rotates to clean the filter 510, thereby preventing a large amount of flocculent dust from being entangled on the brush 772 when the filter 510 is cleaning, thereby interfering with the normal cleaning of the filter 510. The specific workflow is as follows: During operation, the solar photovoltaic bracket to be welded is placed on the placement component 3, so that the solar photovoltaic bracket is welded by the welding robot arm 4, and the exhaust gas generated during welding is filtered by opening the filter component 5, and the welding slag generated during welding is collected by the collection component 7; By turning on the suction machine 54, the suction force generated by the suction machine 54 when it is working is used to absorb the waste gas generated during the welding of the solar photovoltaic bracket, so that the waste gas and welding slag generated by welding enter the inner side of the main body 1 through the anti-blocking component 6, and at the same time, a filter 510 is provided on the top of the connecting plate 511 to block the welding slag entering the main body 1 through the suction force of the suction machine 54, so that the waste gas is sucked into the connecting pipe 52 through the filter 510, and at the same time, the continuous operation of the suction machine 54 makes the waste gas continue to move in the connecting pipe 52, so that the waste gas enters the filter pipe 51, so that the particles in the waste gas are adsorbed by the activated carbon box 53 to filter. The exhaust gas after the exhaust is discharged through the suction machine 54. At the same time, when the suction machine 54 performs the suction work, the connecting frame 58 slides on the sliding rod 55, and at the same time pulls the third spring 57 to move, so that the connecting frame 58 drives the scraper 59 to clean and scrape the inner side of the filter tube 51, thereby avoiding that when the exhaust gas is continuously sucked and filtered, the exhaust gas passes through the filter tube 51 for a long time, and a large amount of exhaust gas impurities will remain on the inner wall of the filter tube 51, causing corrosion to the inner wall of the filter tube 51. At the same time, when the suction machine 54 stops working, the connecting frame 58 is stretched by the reset of the third spring 57, so that the connecting frame 58 drives the scraper 59 to clean and scrape the inner wall of the filter tube 51. When the suction machine 54 is performing suction work, the waste gas and waste chips generated during the welding work are sucked into the inner side of the main body 1 through the mesh plate 61. At the same time, due to the suction force of the suction machine 54, the grid 63 moves downward through the connecting shaft 62, so that the grid 63 drives the extrusion mechanism 65 to move downward together. At the same time, when the suction machine 54 stops suction work, because the welding slag enters the main body 1 together with the waste gas through the suction force of the suction machine 54, a small amount of welding slag will be stuck in the mesh of the mesh plate 61, thereby causing the mesh of the mesh plate 61 to be blocked. When the suction machine 54 stops suction work, the grid 63 is stretched by the reset of the first spring 64, so that the grid 63 drives the extrusion mechanism 65 to move toward the mesh plate 61, so that the extrusion mechanism 65 ejects the impurities stuck in the mesh of the mesh plate 61. When the suction machine 54 stops the suction work, the grid 63 is stretched by the reset of the first spring 64, so that the grid 63 drives the extrusion rod to move toward the mesh plate 61, so that the extrusion rod drives the extrusion block 655 to eject the impurities blocked in the mesh of the mesh plate 61. At the same time, a circle of round edges is provided at the bottom of the extrusion block 655, so that when the extrusion block 655 ejects the impurities blocked in the mesh of the mesh plate 61, the round edge at the bottom of the extrusion block 655 can clean the inner side of the mesh of the mesh plate 61, thereby avoiding impurities remaining on the inner side of the mesh of the mesh plate 61. If it is not cleaned for a long time, a large amount of impurities will accumulate on the inner side of the mesh, causing the mesh of the mesh plate 61 to be blocked. The phenomenon of smaller diameter makes it easier for welding slag to get clogged when passing through. At the same time, when the extrusion block 655 squeezes and dredges the mesh of the mesh plate 61, when impurities are stuck tightly inside the mesh of the mesh plate 61, the extrusion force between the extrusion block 655 and the impurities stuck in the mesh is greater than the tensile force of the second spring 656, so that the extrusion block 655 moves in the notch 652 through the slide bar 654 and the slider 653, thereby avoiding excessive extrusion force between the extrusion block 655 and the impurities stuck in the mesh, which will cause extrusion damage to the extrusion block 655, and also avoiding excessive extrusion force between the impurities stuck between the mesh, which will cause friction damage to the aperture of the mesh, resulting in the phenomenon of enlargement of the aperture of the mesh; When impurities enter the main body 1 through the anti-blocking component 6, the filter screen 510 is arranged on the connecting plate 511, so that the filter screen 510 separates the impurities and exhaust gas entering the inner side of the main body 1, so that the welding slag remains on the connecting plate 511. At the same time, when the welding slag accumulated on the connecting plate 511 needs to be cleaned, the electric hydraulic cylinder 71 is opened, and the output end of the electric hydraulic cylinder 71 drives the push block 76 to move on the connecting plate 511 through the connecting rod 73, so that the push block 76 can remove the accumulated welding slag on the connecting plate 511. 11, so that the welding slag impurities on the connecting plate 511 are pushed into the collecting cylinder 75 through the discharge port 74, and the welding slag accumulated on the connecting plate 511 is cleaned, so as to avoid a large amount of welding slag from accumulating around the filter screen 510 and interfering with the normal suction work of the suction machine 54. At the same time, when the output end of the electric hydraulic cylinder 71 drives the pushing block 76 to move, so that the pushing block 76 drives the rotating mechanism 77 to pass through the filter screen 510, the rotating mechanism 77 cleans the top of the filter screen 510; When the push block 76 drives the rotating rod 771 to reach the top of the filter 510, the suction force generated by the suction machine 54 during operation causes the rotating rod 771 to drive the brush 772 to rotate on the filter 510, so that the brush 772 cleans the top of the filter 510, thereby preventing a large amount of welding slag and dust that follows the welding slag into the inner cavity of the main body 1 from accumulating on the top of the filter 510 when the filter 510 is filtering, thereby clogging the filter 510. At the same time, grabbing rods 774 are provided at both ends of the rotating rod 771, so that when the rotating rod 771 rotates to clean the filter 510, the grabbing rods 774 can grab the floating flocculent dust, thereby preventing a large amount of flocculent dust from being entangled on the brush 772 when the filter 510 is cleaning, thereby interfering with the normal cleaning of the filter 510.
