Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets, and particularly relates to a bracket welding device for the construction of a solar photovoltaic power plant. Background Art

[0002] A photovoltaic bracket is a special bracket for placing, supporting, installing, fixing, and rotating a solar panel in a solar photovoltaic power generation system. As the "skeleton" of a photovoltaic power station, the photovoltaic bracket includes columns and crossbeams. The stability of the photovoltaic bracket is particularly important. Especially in areas with strong winds and large spans, problems with the photovoltaic bracket will directly affect the power generation efficiency and investment returns of the photovoltaic power station. Therefore, high requirements are imposed on the columns and crossbeams. Due to its high strength and good compressive performance, Q235B steel is made into square or rectangular welded pipes and is widely used.

[0003] For the convenience of transportation and operation, the welded pipes usually have a fixed length. During installation, when the crossbeam or some photovoltaic brackets use a single horizontal axis, the welded pipes need to be welded to reach the required length. For the convenience of operation, the welded pipes are welded on the ground and then installed.

[0004] Currently, during welding, the joints of two welded pipes need to be spliced together. Since a single welded pipe has a certain length, it is easy to separate, resulting in inconvenient welding operations. Therefore, during welding, other personnel are required to support the welded pipes. Since the arc light generated during welding causes great harm to the eyes, the welder needs to hold a protective mask in one hand and a welding torch in the other hand for welding. If there is only one auxiliary person, the auxiliary person needs to use both hands to stabilize the two welded pipes respectively, which requires the auxiliary person to be located at the joint of the two welded pipes to conveniently fix the two welded pipes. When the auxiliary person is located at the welding position, the welding gas and smell are relatively close to the auxiliary person, which is easy to cause harm to the body of the auxiliary person. Moreover, during welding, the auxiliary person will turn their head, which is also easy to cause the welded pipes to be misaligned, resulting in welding failure; while configuring two auxiliary persons to support the two welded pipes respectively will waste more human resources and lead to high construction costs. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bracket welding device for the construction of a solar photovoltaic power plant, which does not require the assistance of others, and the welder can weld the welded pipes by himself.

[0006] The bracket welding device for the construction of a solar photovoltaic power plant includes two independent troughs with their openings facing downwards, which are distributed left and right. Through channels for the welded pipes to pass through are opened on the left and right side walls of the troughs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model. The described embodiments only play an explanatory role and should not limit the present utility model.

[0024] A bracket welding device for solar photovoltaic power plant construction described in this embodiment, as Figure 1 and Figure 2 shown, includes two independent trough bodies 1 with their trough openings facing downwards. The two trough bodies 1 are distributed left and right. The trough body 1 is a rectangular structure as a whole. The width of the welding pipe is less than the distance between the front and rear inner side walls of the trough body 1. Channels for the welding pipe to pass through are opened on the left and right side walls of the trough body 1.

[0025] The said channel communicates with the notch of the groove body 1. The two channels on the groove body 1 make the groove body 1 have no left and right side walls, and the whole groove body 1 is in a "C" - shaped structure with the opening facing downwards. In this way, after welding two welded pipes, it is convenient to remove the groove body 1 from the welded pipes. Of course, in some embodiments, the channel is just a through - hole with left - right communication opened on the left and right side walls of the groove body 1. After welding, pulling the welded pipes out from the channel can also complete the separation of the groove body 1 and the welded pipes.

[0026] A first threaded hole is opened on the front side wall of the groove body 1. A first bolt 9 which is in threaded fit with it is arranged in the first threaded hole. The screw rod of the first bolt 9 passes through the first threaded hole and is located inside the groove body 1. When the welded pipe is inside the groove body 1, the screw rod of the first bolt 9 presses the welded pipe against the rear inner side wall of the groove body 1, so as to fix the welded pipe and the groove body 1. The whole content of this paragraph constitutes a locking mechanism for fixing the welded pipe inside the groove body 1.

[0027] Of course, in some embodiments, the locking mechanism can also include a horizontally arranged guide rod. A positioning hole for the guide rod to pass through is opened on the front side wall of the groove body 1. One end of the guide rod passes through the positioning hole and is located inside the groove body 1 and is fixed with a circular plate. The diameter of the guide rod is smaller than the diameter of the circular plate. The guide rod and the circular plate as a whole are in a "T" - shaped structure. A spring is sleeved on the guide rod between the circular plate and the front inner side wall of the groove body 1. In the natural state of the spring, the circular plate is in contact with the welded pipe, and the front end of the guide rod extends beyond the groove body 1. The spring makes the circular plate press the welded pipe tightly against the rear side wall of the groove body 1. When there is no welded pipe in the groove body 1, in order to prevent the front end of the guide rod from passing through the positioning hole, a limiting plate is fixed at the front end of the guide rod. The limiting plate is in a circular structure. The diameter of the positioning hole is smaller than the diameters of the limiting plate and the circular plate. Moreover, the limiting plate is also convenient for pulling the guide rod, so that there is a gap between the circular plate and the welded pipe, thus taking out the welded pipe from the groove body 1.

[0028] Limit grooves communicating inside and outside are opened at one ends of the front and rear side walls of the groove body 1 far from the bottom of the groove. The same baffle 2 is inserted in the limit grooves. The limit grooves are in a square structure, and the baffle 2 is a square plate. The bottom of the groove body 1 is at the top, and the height of the welded pipe is less than the height from the top of the limit groove to the inner bottom of the groove body 1, so that the welded pipe can be located between the baffle 2 and the inner bottom of the groove body 1.

[0029] A second threaded hole communicating with the inside and outside is provided at the bottom of the groove body 1. The second threaded hole is a threaded hole communicating with the upper and lower parts. A second bolt 3 in threaded fit therewith is arranged in the second threaded hole. The screw rod of the second bolt 3 passes through the second threaded hole and is located inside the groove body 1. During use, after the welded pipe is placed inside the groove body 1, the baffle 2 is inserted into the limiting groove, and then the screw rod of the second bolt 3 is screwed downward to make the welded pipe closely contact with the baffle 2. The baffle 2 can prevent the groove body 1 from tilting greatly when the two groove bodies 1 are pulled towards the middle; after welding is completed, the baffle 2 is first pulled out of the limiting groove, and then the groove body 1 is removed from the top of the welded pipe; the whole content of this paragraph constitutes a fixing mechanism for making the baffle 2 closely contact with the welded pipe. Of course, the structure of the fixing mechanism can also be the same as that of the locking mechanism.

[0030] As Figure 1 and Figure 2 shown, a first fixing block 4 is vertically fixed at the bottom of one of the groove bodies 1, and a second fixing block 7 is vertically fixed at the bottom of the other groove body 1. The first fixing block 4 and the second fixing block 7 are parallel to each other left and right. The bottom of the groove body 1 is at the top. The first fixing block 4 is fixed to the top of the left groove body 1, and the second fixing block 7 is fixed to the top of the right groove body 1. A first screw rod 5 is vertically fixed on the side of the first fixing block 4 close to the second fixing block 7. The first screw rod 5 is vertically fixed on the right side wall of the first fixing block 4. A fixing pipe 6 in threaded fit therewith is sleeved on the first screw rod 5. An internal thread in threaded fit with the first screw rod 5 is provided on the inner side wall of the fixing pipe 6.

[0031] A first through hole for the fixing pipe 6 to pass through is provided on the second fixing block 7. One end of the fixing pipe 6 passes through the first through hole and is fixed with a limiting block 8. The limiting block 8 is located on the right side of the second fixing block 7. The limiting block 8 is used to prevent the fixing pipe 6 from passing through the first through hole. The limiting block 8 is fixed to the right end of the fixing pipe 6. The limiting block 8 is a circular plate. The outer diameter of the fixing pipe 6 is smaller than the diameter of the limiting block 8, and the diameter of the first through hole is smaller than the diameter of the limiting block 8, so as to prevent the limiting block 8 from passing through the first through hole, thereby preventing the right end of the fixing pipe 6 from passing through the first through hole and being located between the first fixing block 4 and the second fixing block 7. Of course, the limiting block 8 can also be several pieces, which are evenly fixed on the outer side wall of the right end of the fixing pipe 6, and can also prevent the right end of the fixing pipe 6 from passing through the first through hole and being located between the first fixing block 4 and the second fixing block 7; by rotating the fixing pipe 6, the combined length of the first screw rod 5 and the fixing pipe 6 can be adjusted. When the distance between the fixing pipe 6 and the first screw rod 5 becomes smaller, the fixing pipe 6 moves towards the middle, which will drive the limiting block 8 to move. The second fixing block 7 blocks the limiting block 8, so the limiting block 8 will push the second fixing block 7, so that the welding ends of the two welded pipes contact, preventing the two welded pipes from separating, so as to facilitate welding. The whole content of this paragraph constitutes a connecting component for connecting the fixing pipe 6 with the second fixing block 7 and enabling the fixing pipe 6 to rotate independently.

[0032] A bearing is installed between the fixed pipe 6 and the first through hole. The outer ring of the bearing is fixed to the first through hole, and the inner ring of the bearing is fixedly sleeved on the fixed pipe 6. The bearing can prevent gaps between the fixed pipe 6 and the first through hole, reduce the offset of the fixed pipe 6 in the first through hole, increase the stability between the fixed pipe 6 and the second fixing block 7, and also facilitate pulling the second fixing block 7. The limiting block 8 can serve as a backup. When the bearing is damaged, the second fixing block 7 can be pulled by the limiting block 8. Of course, in some embodiments, the connecting component can be provided with only the bearing. The above three paragraphs of content together constitute an adjusting mechanism for adjusting the distance between the two troughs 1.

[0033] As Figure 3 and Figure 4 shown, a first fixing block 4 is vertically fixed to the bottom of one of the troughs 1, and a second fixing block 7 is vertically fixed to the bottom of the other trough 1. The bottom of the trough 1 is located at the top. The first fixing block 4 is fixed to the top of the left trough 1, and the second fixing block 7 is fixed to the top of the right trough 1. The first fixing block 4 and the second fixing block 7 are parallel to each other left and right and are both provided with second through holes for the second screw 11 to pass through. One end of the second screw 11 passes through the second through hole on the second fixing block 7 and is fixed with a limiting plate 12. The limiting plate 12 is used to prevent the second screw 11 from passing through the second through hole. The right end of the second screw 11 is located on the right side of the second fixing block 7 and is fixed with a limiting plate 12. The limiting plate 12 is circular in shape. The diameter of the second through hole is smaller than the diameter of the limiting plate 12. The other end of the second screw 11 passes through the second through hole of the first fixing block 4 and is provided with a nut 10 that is in threaded cooperation with it. The nut 10 is located on the second screw 11 on the left side of the first fixing block 4. When in use, by screwing the nut 10 to the right, the nut 10 pushes the first fixing block 4 to the right, so that the first fixing block 4 and the second fixing block 7 drive the two troughs 1 to move towards the middle, making the two welded pipes contact. The above content as a whole constitutes another structure of the adjusting mechanism for adjusting the distance between the two troughs 1.

[0034] Both the first fixing block 4 and the second fixing block 7 are provided with two pieces. When the nut 10 is screwed, when the first fixing block 4 and the second fixing block 7 move, the friction between the first fixing block 4 and the second fixing block 7 and the second screw 11 can be reduced, so that the screwing of the nut 10 is smoother.

[0035] Working principle:

[0036] When installing a photovoltaic support, first weld the welded pipes on the ground. When welding two welded pipes, place one welded pipe into the left slot 1, so that the right end of the left welded pipe extends beyond the left slot 1, and fix the left welded pipe to the left slot 1; the other welded pipe is located in the right slot 1, and make the left end of the right welded pipe extend beyond the right slot 1, and then fix the right welded pipe to the right slot 1. Then adjust the distance between the two slots 1 to make the distance between the two slots 1 smaller, that is, the two slots 1 move towards the middle, thereby driving the two welded pipes to move towards the middle so that the two welded pipes are in contact. The welder directly uses a welding torch to weld the two welded pipes. In this process, since the two welded pipes are brought into contact through the slot 1 and the adjustment mechanism, there is no need for other auxiliary personnel to support the welded pipes, which saves human resources, and there is no need for other personnel to assist, and it can also avoid harm to personnel during welding.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
