Description

Technical Field

[0001] The utility model belongs to the technical field of composite material pipe piles, and particularly relates to a photovoltaic composite material pipe pile. Background Technique

[0002] In recent years, China's photovoltaic industry has developed rapidly. In order to save agricultural land, pipe piles are gradually driven deep into deserts, lakes and seas to support photovoltaic power generation components for power generation. In the case of poor geology, the pipe piles need to be driven to a deeper depth to meet the requirements for installing photovoltaic power generation components. The production of long photovoltaic composite material pipe piles requires high production capacity, and most manufacturers are unable to produce them. The commonly used method in construction is to butt the photovoltaic composite material pipe piles on site.

[0003] At present, the commonly used butt joint method for photovoltaic composite material pipe piles is threaded meshing connection. When butt jointing composite material pipe piles in this way, the photovoltaic composite material pipe piles need to be rotated many times and sufficient force needs to be applied to fix and connect them together. The butt joint process is very time-consuming and laborious, affecting work efficiency. Moreover, when using a vibrating hammer to insert the pipe pile for the combined composite material pipe pile, the high-frequency vibration will loosen the tightened threads, and it is possible that the two sections of composite material pipe piles originally meshed by threads will be separated, seriously affecting the project quality.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a photovoltaic composite material pipe pile.

[0005] The information disclosed in this background technical section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art.

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] like Figures 1 to 5As shown in the figure, a photovoltaic composite pipe pile in an embodiment of the present utility model includes a first pipe body 1 and a second pipe body 2, and a locking assembly is provided between the first pipe body 1 and the second pipe body 2. The locking assembly includes a connecting column 3 welded to the first pipe body 1. A plurality of uniformly distributed sliders 31 are integrally formed on the connecting column 3. A positioning groove 22 matching the connecting column 3 is provided on the second pipe body 2. A plurality of sliding grooves 203 each matching the sliders 31 are formed on the groove wall of the positioning groove 22, and a rotating groove 201 matching the sliders 31 is further formed on the groove wall of the positioning groove 22.

[0030] Specifically, the slider 31 is slidably connected in the sliding groove 203. When the slider 31 slides to the bottom of the sliding groove 203, it enters the rotating groove 201. At this time, when the first pipe body 1 is rotated, the slider 31 rotates in the rotating groove 201. When the side wall of the slider 31 abuts against the side wall of the rotating groove 201, the first pipe body 1 is clamped to the second pipe body 2 through the slider 31 on the connecting column 3.

[0031] It should be noted that when inserting the pipe pile into the foundation, the vibration hammer will vibrate at a high frequency, and the vibration will cause the first pipe body 1 and the second pipe body 2 to rotate relative to each other. If the slider 31 happens to rotate from the rotating groove 201 to the position of the sliding groove 203, due to the different pressures in the foundation at different depths, it may cause the first pipe body 1 and the second pipe body 2 inserted into the foundation to separate, resulting in an engineering quality accident.

[0032] In order to prevent the connecting column 3 from rotating in the second pipe body 2, a fixed card slot 2011 is formed on the upper groove wall of the rotating groove 201. The number of the fixed card slots 2011 is the same as that of the sliding grooves 203, and the fixed card slots 2011 and the sliding grooves 203 are alternately distributed in sequence. The included angle between the fixed card slot 2011 and the sliding groove 203 is 45°. When docking the first pipe body 1 and the second pipe body 2, only need to rotate the second pipe body 2 by 45°. Under the action of gravity, the fixed card slot 2011 can clamp the slider 31, and the connecting column 3 cannot rotate in the positioning groove 22 on the second pipe body 2. At the same time, the lower end face of the second pipe body 2 is docked on the upper end face of the first pipe body 1 to realize the connection between the first pipe body 1 and the second pipe body 2. Compared with the traditional thread meshing connection method, the above connection method can quickly complete the docking of the first pipe body 1 and the second pipe body 2.

[0033] Furthermore, as Figures 2 to 5 shown, the connecting column 3 is cylindrical, and the lower half of the connecting column 3 is inserted into the first pipe body 1. Since the lengths of the first pipe body 1 and the second pipe body 2 after connection are relatively long, when using a vibration hammer to clamp the upper end of the second pipe body 2 for inserting the pipe pile, the connection between the first pipe body 1 and the second pipe body 2 is in the middle position and is subjected to a large force. The connecting column 3 can strengthen a section of the pipe wall where the first pipe body 1 and the second pipe body 2 are connected, preventing the connection between the first pipe body 1 and the second pipe body 2 from being damaged due to excessive force.

[0034] Furthermore, a limit plate 21 is welded on the inner wall of the second tube body 2, and the distance between the limit plate 21 and the fixed slot 2011 matches the distance between the upper end surface of the connecting column 3 and the upper end surface of the slider 31. When the slider 31 is engaged in the fixed slot 2011, the upper end surface of the connecting column 3 is connected to the lower end surface of the limit plate 21.

[0035] Specifically, because the upper end surface of the connecting column 3 is connected to the lower end surface of the limiting plate 21, when the vibration hammer is pressed down, the limiting plate 21 presses on the connecting column 3 to share the pressure on the slider 31. At the same time, the limiting plate 21 also has a certain support force and pulling force on the inner wall of the second tube body 2, preventing the second tube body 2 from being deformed after being subjected to force due to the decrease in strength due to the opening of the rotating groove 201 and the sliding groove 203, and the slider 31 cannot be firmly stuck in the fixed groove 2011.

[0036] Furthermore, a ground-breaking cone 11 is fixedly connected to the lower end of the first tube body 1 to reduce the unit contact area between the first tube body 1 and the ground, making it easier to insert the first tube body 1 into the foundation.

[0037] In order to enhance the stability of the connection between the first tube body 1 and the second tube body 2, as Figures 3 to 6 As shown, a plurality of placement grooves 101 are provided on the upper end surface of the first tube body 1, and the placement grooves 101 are on the same central axis as the slider 31. A limit assembly is installed in the placement groove 101, and the limit assembly includes a spring 12 and a locking pin 13. One end of the spring 12 is welded to the bottom wall of the placement groove 101, and the other end of the spring 12 is welded to the locking pin 13. A plurality of limit grooves 202 are provided on the lower end surface of the second tube body 2, and the limit grooves 202 match the positions of the fixed card slots 2011.

[0038] Specifically, when the connecting column 3 is inserted into the second tube body 2, the lower end surface of the second tube body 2 is pressed on the locking pin 13, and the locking pin 13 presses against the spring 12, causing the spring 12 to retract. The first tube body 1 is rotated, and when the slider 31 is rotated to the position of the fixed slot 2011, the locking pin 13 is inserted into the limiting slot 202 under the elastic force of the spring 12, further limiting the second tube body 2, and achieving the docking of the first tube body 1 and the second tube body 2. When the vibrating hammer clamps the upper end of the second tube body 2 to insert the pipe pile, the second tube body 2 clamps the slider 31 in the fixed slot 2011 under the action of gravity. Because the locking pin 13 is inserted into the limiting slot 202 and the fixed slot 2011 and the slider 31 are engaged, the connection between the first tube body 1 and the second tube body 2 is more stable.

[0039] Further, a rotating bead 131 is rotatably connected to the locking pin 13. When the second tube body 2 and the first tube body 1 are butted, the lower end surface of the second tube body 2 presses on the rotating bead 131, and the rotating bead 131 supports the second tube body 2. When the slider 31 rotates in the rotating groove 201, the rotating bead 131 rotates on the locking pin 13, making the butting work more labor-saving.

[0040] As Figure 3 and Figure 5 shown, a plurality of through holes 204 are formed in the outer wall of the second tube body 2. The through holes 204 penetrate through the two side walls, the limiting groove 202 and the connecting column 3 of the second tube body 2. After the first tube body 1 and the second tube body 2 are butted, connecting members such as steel pipes and long bolt can be inserted into the through holes 204, which can further enhance the connection stability between the first tube body 1 and the second tube body 2.

[0041] Because the photovoltaic project covers a large area and has a long project duration, once an unexpected situation that affects local development occurs, when the photovoltaic power generation project is relocated, the connected first tube body 1 and second tube body 2 are pulled out from the foundation. For convenient transportation, it is necessary to separate the first tube body 1 and the second tube body 2. At this time, a disassembly tool can be inserted into the through hole 204, and the locking pin 13 is pressed down, so that the second tube body 2 can be separated from the first tube body 1, facilitating reuse after transportation.

[0042] An anti-aging layer is provided on the surfaces of the first tube body 1 and the second tube body 2. The anti-aging layer is an aliphatic polyurethane resin layer, which has wear resistance. When inserting the pipe pile, it can effectively prevent the tube body from being scratched by stones or other hard objects in the foundation.

[0043] During use, the second tube body 2 is sleeved on the connecting column 3, and the second tube body 2 is rotated to align the slider 31 on the connecting column 3 with the sliding groove 203 on the second tube body 2. The second tube body 2 is pushed towards the first tube body 1, and the slider 31 can slide into the sliding groove 203. When the slider abuts against the upper groove wall of the rotating groove 201, the locking pin 13 is compressed into the placement groove 101 by the end surface of the second tube body 2. The second tube body 2 is rotated. When the locking pin 13 corresponds to the limiting groove 202, under the resilience of the spring 12, the locking pin 13 is inserted into the limiting groove 202, and the first tube body 1 and the second tube body 2 cannot rotate. At this time, the slider 31 just rotates to the position of the fixed card slot 2011. The butted first tube body 1 and second tube body 2 are made vertical. Under the action of gravity, the second tube body 2 drops downward, and the rotating groove 201 on the second tube body 2 catches the slider 31, and the end surfaces of the first tube body 1 and the second tube body 2 are joined, thus completing the butting work of the first tube body 1 and the second tube body 2.
