Description
Technical Field
[0001] This utility model relates to the field of pipe pile construction technology, and in particular to a concrete photovoltaic pipe pile connection structure. Background Technology
[0002] In photovoltaic power station projects, concrete photovoltaic pipe piles are the core components that directly bear the load of photovoltaic brackets and panels. The connection structure of the pipe piles is the key link to realize the splicing of multiple pipe piles and form a complete support system. It transfers the force of the upper and lower pipe piles to the overall structure and is the basis for the long-term stable support of the photovoltaic brackets by the pipe piles.
[0003] The existing connection of concrete photovoltaic pipe piles generally adopts the flange connection method. The upper and lower pipe pile ends are prefabricated fixed flanges. Each flange has threaded holes evenly opened along the circumference and is equipped with corresponding bolts. During construction, the upper pipe pile is first lifted by the lifting equipment, and after aligning the upper and lower pipe piles, the bolts are inserted through the threaded holes. The upper and lower flanges are tightly fitted through the threaded connection to complete the threaded connection and fixation of the pipe pile.
[0004] In actual construction, existing connection methods suffer from the following drawbacks: the lack of a dedicated guiding and restraining structure makes radial misalignment of the pipe piles prone to occur when there is wind interference or operational errors of the lifting equipment at the construction site. Furthermore, the alignment of the threaded holes can only be calibrated manually, and when the threaded holes of the upper and lower flanges are misaligned, the bolts cannot be smoothly inserted. In addition, in the construction of large-scale photovoltaic power plants, the above manual connection process must be repeated for each section of the pipe pile, which not only slows down the overall construction progress but also causes deviations in the connection of some pipe piles due to operational errors, affecting the subsequent force transmission effect. Therefore, a concrete photovoltaic pipe pile connection structure is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a concrete photovoltaic pipe pile connection structure, which aims to improve the problems of deviation in pipe pile docking and low construction efficiency caused by the lack of a guiding constraint structure in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A concrete photovoltaic pipe pile connection structure includes a pipe pile, a connection mechanism installed at the bottom end of the pipe pile, a reinforcement mechanism installed at the bottom end of the pipe pile, and a protective mechanism installed on the outside of the connection mechanism. The connecting mechanism includes a flange one, the top of which is fixedly connected to the bottom of the pipe pile. The flange one has multiple threaded slots inside, and bolts are threaded into the threaded slots. The bottom of the bolts is threaded to a flange two, and a guide assembly is provided at the bottom of the flange one. As a further description of the above technical solution: The reinforcement mechanism includes an annular rib plate, the annular rib plate is fixedly connected to the inside of the pipe pile, the annular rib plate is provided with toothed grooves on the outside, and a steel cage is fixedly connected to the inside of the pipe pile. As a further description of the above technical solution: The protective mechanism includes an anti-corrosion sleeve, the bottom end of which is fixedly connected to the top of the flange one, and multiple protective plates are fixedly connected to the outside of the anti-corrosion sleeve. A sealing gasket is fixedly connected to the bottom end of the flange one. As a further description of the above technical solution: The guide assembly includes an outer guide ring, the bottom end of which is fixedly connected to the top end of the second flange. The top end of the second flange has multiple oblique grooves. The bottom end of the first flange is fixedly connected to multiple wedge blocks, and the bottom end of the first flange is fixedly connected to an inner guide ring. As a further description of the above technical solution: The inside of the anti-corrosion sleeve is fixedly connected to the outside of the pipe pile, and the bottom end of the protective plate is fixedly connected to the top end of the flange. As a further description of the above technical solution: The annular rib is fixedly connected to the inside of the flange, and the outside of the reinforcing cage is in contact with the inside of the toothed groove. As a further description of the above technical solution: The outer guide ring is internally slidably connected to the outside of the inner guide ring, and the inside of the inclined groove is in contact with the outside of the wedge block; As a further description of the above technical solution: An anchoring hole is provided inside the flange, and the outside of the steel cage is fixedly connected to the inside of the anchoring hole.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the outer guide ring and the inner guide ring cooperate to align the axis of the connecting mechanism. At the same time, the wedge block and the inclined groove cooperate to automatically align and calibrate the threaded hole groove, realizing the rapid and accurate docking of the pipe pile. This reduces the requirements for operational precision in on-site construction and avoids stress concentration caused by forcibly inserting bolts, thus meeting the efficiency and safety requirements of pipe pile construction.
[0008] 2. In this utility model, the vertical load and shear force are distributed to the inside of the pipe pile through the synergistic effect of the annular rib plate and the steel cage, avoiding the load concentration at the connection edge, and significantly improving the torsional resistance of the connection, effectively preventing cracking at the end of the pipe pile due to excessive local stress, and extending the overall service life of the pipe pile.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Example: A concrete photovoltaic pipe pile connection structure, referring to Figures 1 to 3 It includes a pipe pile 1, a connecting mechanism 2 installed at the bottom end of the pipe pile 1, a reinforcing mechanism 3 installed at the bottom end of the pipe pile 1, and a protective mechanism 4 installed on the outside of the connecting mechanism 2. The connecting mechanism 2 includes a flange 21, which is a ring-shaped steel plate structure that can evenly transfer the load borne by the pipe pile 1 to the connection node. The flange 21 has multiple threaded slots 22 inside, which are evenly distributed along the circumference of the flange 21. Bolts 23 are threaded inside the threaded slots 22. The length of the bolt 23 is slightly greater than the sum of the thicknesses of the flange 21 and the flange 24. They are tightly connected by threaded engagement. The bottom end of the bolt 23 is threaded to the flange 24 for fixed connection with the top end of another section of pipe pile 1. A guide component 25 is provided at the bottom end of the flange 21. The guide component 25 is used to achieve precise alignment between the flange 21 and the flange 24. The guide assembly 25 includes an outer guide ring 251, which is an annular boss structure. The bottom end of the outer guide ring 251 is fixedly connected to the top end of the second flange 24 and is concentrically arranged with the second flange 24 to provide radial guiding constraint. The top end of the second flange 24 has multiple inclined grooves 252, which are evenly distributed along the circumference of the second flange 24 and alternate with the threaded hole grooves 22. The bottom end of the first flange 21 is fixedly connected to multiple wedges 253, which correspond one-to-one with the inclined grooves 252, enabling docking. During the process, the flange 21 is pushed along the inclined groove 252 to make a fine adjustment of its position. The bottom end of the flange 21 is fixedly connected to the inner guide ring 254. The inner guide ring 254 is concentrically set with the flange 21 and its height is the same as that of the outer guide ring 251. The inner part of the outer guide ring 251 is slidably connected to the outer part of the inner guide ring 254, which can limit the radial offset of the flange 21 and the flange 24 and ensure that the central axis is accurately aligned. The inside of the inclined groove 252 is in contact with the outside of the wedge 253, and the inclined surfaces of the two are tightly fitted. Specifically, during the docking process, the pipe pile 1 with flange 21 is lowered, the inner guide ring 254 enters the outer guide ring 251, and the radial offset of the connection structure is corrected by the guide constraint. The axis is initially aligned. As it continues to be lowered, the wedge 253 contacts the inclined groove 252. The lateral component force generated when the wedge 253 slides along the inclined groove 252 can automatically correct the circumferential misalignment of flange 21 and flange 24, so that the threaded hole groove 22 is accurately aligned.
[0013] Reference Figure 1 , Figure 2 and Figure 4The reinforcement mechanism 3 includes an annular rib plate 31, which is a metal annular plate. The annular rib plate 31 is fixedly connected to the inside of the pipe pile 1, which can enhance the structural strength of the end of the pipe pile 1. The annular rib plate 31 has a toothed groove 32 on its outside. The toothed groove 32 is a triangular groove that is evenly distributed along the circumference of the annular rib plate 31. The pipe pile 1 is fixedly connected to a steel cage 33 to provide support for the pipe pile 1. The annular rib plate 31 is fixedly connected to the inside of the flange 21 to realize the rigid connection between the rib plate and the flange. The outside of the steel cage 33 is in close contact with the inside of the toothed groove 32, which enhances the force transmission effect through interlocking. The flange 21 has an anchoring hole inside. The outside of the steel cage 33 is fixedly connected to the inside of the anchoring hole by concrete pouring, forming a double fixation. The protective mechanism 4 includes a corrosion-resistant sleeve 41, which has salt and alkali resistance and anti-aging properties. The bottom end of the corrosion-resistant sleeve 41 is fixedly connected to the top end of the flange 21. Multiple protective plates 42 are fixedly connected to the outside of the corrosion-resistant sleeve 41. The protective plates 42 are evenly distributed along the circumference of the corrosion-resistant sleeve 41 and can resist external impact. A sealing gasket 43 is fixedly connected to the bottom end of the flange 21 to prevent rainwater from seeping into the mating surface. The inside of the corrosion-resistant sleeve 41 is fixedly connected to the outside of the pipe pile 1 to form a corrosion barrier for the transition section at the connection. The bottom end of the protective plate 42 is fixedly connected to the top end of the flange 21 to further enhance the protective stability. Specifically, the reinforcing cage 33 passes through the anchoring hole of the flange 21 and is embedded in the toothed groove 32 of the annular rib 31, so that the reinforcing cage 33 is tightly connected with the flange 21 and the toothed groove 32 to form a stable force transmission system. The load can be transmitted to the annular rib 31 through the flange 21, and then distributed to the reinforcing cage 33 through the toothed groove 32, and finally transmitted to the entire pipe pile 1. At the same time, the anti-corrosion sleeve 41 wraps the transition section between the pipe pile 1 and the flange 21, the protective plate 42 resists external impact, and the sealing gasket 43 seals the flange joint gap to ensure the long-term stability of the pipe pile connection node.
[0014] The implementation principle of this application embodiment is as follows: During construction and docking, the lower section of pipe pile 1 is first driven into the pre-set foundation and its verticality is calibrated using a pile driving device. The upper section of pipe pile 1 is then lifted by a lifting device. During the lowering process, the inner guide ring 254 moves down with flange 1 21 and is embedded in the outer guide ring 251 at the top of flange 24. The offset is corrected by radial constraint, and the center is initially aligned. As the lowering continues, the wedge 253 at the bottom of flange 1 21 is embedded in the inclined groove 252 of flange 24. The wedge 253 slides along the inclined surface to generate lateral thrust, which drives flange 1 21 to make fine adjustments so that the threaded hole groove 22 is precisely aligned. Finally, the bolt 23 is inserted into the aligned threaded hole groove 22 and the bolt 23 is tightened to achieve docking. During the long-term use of the pipe pile 1, the vertical snow load and horizontal wind load borne by the photovoltaic support and panel will be transferred to the connection. At this time, the flange 21 will evenly transfer the load to the annular rib 31. The annular rib 31 will distribute the load to the reinforcing cage 33 through the triangular toothed groove 32 on the outside. Finally, the reinforcing cage 33 will transfer the load to the concrete body of the pipe pile 1, effectively avoiding concrete cracking or deformation at the connection due to load concentration. At the same time, the anti-corrosion sleeve 41 installed on the transition section of the outer wall of the pipe pile 1 can isolate the salt and alkali components in the soil, rainwater and other corrosive media. The protective plate 42 on the outside of the anti-corrosion sleeve 41 can protect the connection part. The sealing gasket 43 at the bottom of the flange 21 will tightly seal the upper and lower joint gaps to prevent water from seeping into the interior and ensure the long-term stable operation of the connection node.
