Description

Technical Field

[0002] Photovoltaic pile foundation refers to the basic structure formed by piling reinforced concrete steel pipe piles or steel pipe piles. It is a key component in the solar photovoltaic system and is mainly used to support and fix solar panels.

[0003] A Chinese patent with announcement number CN216920332U discloses an auxiliary positioning device for the pile foundation construction of photovoltaic brackets. This solution fixes the telescopic plate on the pile ring through screws, which is easy to install. The threaded rod drives the telescopic plate to slide in the telescopic sleeve. The sliding of the telescopic plate drives another telescopic plate on the same straight line to slide to the corresponding distance in the telescopic sleeve, effectively ensuring that the distance between the piles is consistent with the distance for installing photovoltaic components, and facilitating the adjustment of the spacing between multiple telescopic plates in the corresponding telescopic sleeve. The operation is convenient, saving time and effort, and reducing the work intensity of the user.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 11As shown, a positioning device for photovoltaic pile foundation construction described in an embodiment of the present invention includes a base plate 1, a material discharge component and a fixing component, both of which are arranged above the base plate 1, a plurality of material discharge columns 2 are fixedly installed on the top of the base plate 1, a plurality of positioning rings 3 are arranged on the inner wall of the material discharge column 2, a plurality of conical columns are fixedly installed on the bottom of the positioning ring 3, a positioning hole 4 is opened on the top of the base plate 1, and a plurality of material discharge columns 2 are distributed in a circular array with the center of the positioning hole 4 as the axis, the material discharge component is used to push out the positioning ring 3 in the material discharge column 2 for material discharge, and the fixing component is used to press the positioning ring 3 pushed out by the material discharge component into the ground for fixing; when working, the positioning ring 3 for positioning the photovoltaic pile foundation is placed on the inner side of the material discharge column 2, and then the device is moved to the construction position. After the device is moved to the construction point, the position of the base plate 1 is adjusted so that the center of the base plate 1 is aligned with the construction point. When performing the alignment work, the construction personnel apply the paint on the construction point measured in advance. The markings such as paint that matches the positioning hole 4 are made on the top. Since the positioning hole 4 is opened in the center of the base plate 1, the alignment between the positioning hole 4 and the ground paint can be observed to determine whether the device has been correctly set in the predetermined position. If the positioning hole 4 completely coincides with the ground paint or meets the predetermined alignment standard, it can be considered that the device has been correctly aligned, thereby facilitating positioning. After the device is positioned, the positioning ring 3 located at the bottom of each discharge column 2 is pushed out through the feeding structure, and then the positioning ring 3 is pressed down under the action of the fixing component, so that the conical column at the bottom of the positioning ring 3 is inserted into the soil, thereby completing the fixation of the positioning ring 3 and then completing the positioning work. After the positioning ring 3 is fixed, the other components are assembled with the positioning ring 3 to form the outer frame of the photovoltaic pile foundation, which is convenient for the subsequent construction of the photovoltaic pile foundation. Through the above scheme, rapid positioning before the construction of the photovoltaic pile foundation and rapid installation of the outer frame can be achieved, effectively improving work efficiency.

[0037] like Figures 1 to 5As shown, the material unloading assembly includes an automatic telescopic rod 5, a push roller 6, a push plate 7 and a transmission mechanism. The automatic telescopic rod 5 is fixedly installed on the inner wall of the bottom plate 1, and the transmission mechanism is arranged on the outer wall of the automatic telescopic rod 5. The number of push plates 7 is several and they are distributed on the top of the bottom plate 1 in a circular array with the center of the positioning hole 4 as the axis. The bottom of the push plate 7 is slidably connected with the top of the bottom plate 1. The number of push rollers 6 is several and they are respectively arranged on the top of several push plates 7. Several push plates 7 are respectively located on one side of several discharge columns 2 close to the bottom. The material unloading assembly is automatically The movable telescopic rod 5 causes the transmission mechanism to move, and the movement of the transmission mechanism drives the push roller 6 to move. When the push roller 6 moves, it pushes the push plate 7 to extrude the positioning ring 3 located in the discharge column 2, thereby realizing automatic unloading. When unloading, the push roller 6 is driven to move outward through the contraction of the automatic telescopic rod 5. When the push roller 6 moves, it pushes the push plate 7 to move. When the push plate 7 moves, one end of the push plate 7 is inserted into the inner side of the discharge column 2, thereby extruding a positioning ring 3 located at the bottom of the inner side of the discharge column 2, thereby realizing the effect of automatic unloading.

[0038] like Figures 1 to 5 and Fig. 9 As shown, the transmission mechanism includes a lifting plate 8 fixedly mounted on the outer wall of the automatic telescopic rod 5, a plurality of rotating plates 9 are rotatably mounted on the inner wall of the lifting plate 8, the inner walls of the plurality of rotating plates 9 away from the lifting plate 8 are rotatably connected to the outer walls of the plurality of push rollers 6, a force block 10 is fixedly connected to the top of the push plate 7, the force block 10 is respectively in conflict with the push rollers 6, and a plurality of unloading boxes 11 are fixedly mounted on the outer wall of the bottom plate 1; when working, the automatic telescopic rod 5 is started to retract, and when the automatic telescopic rod 5 is retracted, the section connected to the lifting plate 8 is retracted first, Figure 1 and Fig. 9 When the lifting plate 8 is lowered, the lifting plate 8 will be lowered, and the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8. When the lifting plate 8 is lowered, the lifting plate 8 will be lowered to the lifting plate 8.

[0039] like Figures 1 to 5As shown, a plurality of groups of fixed blocks 12 are fixedly installed on the top of the bottom plate 1, and a group of moving blocks 13 are fixedly installed on the outer wall of each push plate 7. The outer wall of the fixed block 12 is fixedly installed with a limiting rod 14, and the outer wall of the limiting rod 14 is slidably connected with the inner wall of the moving block 13 respectively. Elastic members 15 are fixedly installed between the corresponding fixed blocks 12 and the outer walls of the moving blocks 13 and respectively located on the outer side of the limiting rod 14; when the positioning ring 3 is falling, the moving block 13 will be driven to move with the movement of the push plate 7. When the moving block 13 moves, it will be limited by the limiting rod 14, thereby limiting the push plate 7 and making the push plate 7 move in a preset direction. With the movement of the push plate 7, the moving block 13 squeezes the elastic member 15, so that the elastic member 15 is in a compressed state. When the positioning ring 3 is fixed, the automatic telescopic rod 5 is extended to make the push roller 6 retreat, and the push plate 7 will be reset under the action of the reverse elastic force of the elastic member 15, so as to prepare for the next work.

[0040] like Figures 1 to 9 As shown, a lower pressure plate 16 is fixedly installed at one end of the automatic telescopic rod 5, and the inner wall of the lower pressure plate 16 is slidably connected to the outer wall of the discharge column 2. A plurality of extension plates 17 are fixedly installed on the outer wall of the lower pressure plate 16, and a lower pressure column 18 is fixedly installed at the bottom of the extension plate 17. A lower pressure head 19 is fixedly installed at one end of the lower pressure column 18 away from the extension plate 17, and a plurality of lower pressure heads 19 are respectively located above a plurality of discharge boxes 11; the uppermost section of the automatic telescopic rod 5 is connected to the lower pressure plate 16, and when the device completes the discharge work of the positioning ring 3, the section connected to the lifting plate 8 The automatic telescopic rod 5 shrinks to the minimum value, at which time the automatic telescopic rod 5 will continue to shrink, the lifting plate 8 will no longer descend, and the lower pressure plate 16 at one end of the automatic telescopic rod 5 will continue to descend. When the lower pressure plate 16 descends, it will drive the extension plate 17 to descend, and when the extension plate 17 descends, it will drive the lower pressure head 19 to descend through the lower pressure column 18. Since the lower pressure head 19 is located above the discharge box 11, after the lower pressure head 19 descends, it will pass through the discharge box 11 to squeeze the positioning ring 3, so that the conical column at the bottom of the positioning ring 3 is inserted under the ground, thereby realizing automatic fixation of the positioning ring 3.

[0041] like Figure 1 to Figure 2As shown, the outer wall of the lifting platform 8 is symmetrically fixed with a support plate 20, and a plurality of support legs 21 are fixedly installed at the bottom of the support plate 20, and a support foot 22 is fixedly installed at one end of the support leg 21 away from the support plate 20; when the lifting platform 8 is lowered for unloading, the lifting platform 8 will drive the support plate 20 to descend, and when the support plate 20 descends, the support foot 22 will be driven to descend through the support leg 21. Before the positioning ring 3 falls, the support foot 22 will first contact the ground, thereby lifting the device up. At this time, the moving guide wheel 33 no longer plays a role, thereby preventing the device from deviating during subsequent unloading and fixing work and increasing the overall stability of the device during operation, thereby ensuring the positioning accuracy. In addition, a spirit level is also provided on the base plate 1, by which the spirit level can be used to detect whether the base plate 1 is in a horizontal state. If the base plate 1 is tilted due to an uneven construction position, the base plate 1 can be adjusted by adjusting the support legs 21 to keep the base plate 1 level, thereby ensuring the construction accuracy.

[0042] like Figures 1 to 6 As shown, a reinforcing plate 23 is fixedly installed between the ends of the discharge column 2 away from the bottom plate 1, a discharge trough 24 is provided on the top of the reinforcing plate 23, and a feeding trough 25 is provided on the outer wall of the discharge column 2 located above the discharge trough 24; the position of the discharge column 2 near the top is connected by the reinforcing plate 23, so as to increase the overall stability of the discharge column 2 and prevent the discharge column 2 from tilting. At the same time, when discharging, the positioning ring 3 is placed on the inner side of the discharge trough 24 and moves along the discharge trough 24 to the feeding trough 25, and finally the positioning ring 3 is sent into the inner side of the discharge column 2 through the feeding trough 25, so as to increase the convenience during discharging and make the device more convenient to use.

[0043] like Figures 1 to 10 As shown, a discharge barrel 26 is fixedly installed at the bottom of the discharge box 11, and observation grooves 27 are provided on the outer walls of the discharge barrel 26 and the discharge column 2, and square openings 28 are provided on the tops of the lifting plate 8 and the lower pressure plate 16; the discharge barrel 26 is arranged at the bottom of the discharge box 11, and when the positioning ring 3 enters the discharge box 11 to fall, the falling positioning ring 3 will fall along the discharge barrel 26, thereby preventing the positioning ring 3 from shifting when falling, and the observation grooves 27 provided on the discharge barrel 26 and the discharge column 2 make it convenient for construction personnel to understand the situation of the positioning ring 3 inside the device, and the lifting plate 8 and the lower pressure plate 16 are located above the positioning hole 4, and by providing square openings 28 on the lifting plate 8 and the lower pressure plate 16, it is convenient for construction personnel to better observe the positioning hole 4, thereby facilitating positioning work.

[0044] like Figures 1 to 8As shown, a plurality of sliders 29 are fixedly installed on the inner wall of the lower pressure plate 16, a slide groove 30 is opened on the outer wall of the discharge column 2, and the sliders 29 are slidably installed on the inner walls of the slide groove 30 respectively, and a limiting column A31 and a limiting column B32 are fixedly installed on the top of the bottom plate 1, and the inner wall of the lifting plate 8 is slidably connected to the outer wall of the limiting column A31, and the inner walls of the lower pressure plate 16 and the support plate 20 are slidably connected to the outer wall of the limiting column B32; through the cooperation of the sliders 29 and the slide groove 30, the lower pressure plate 16 is limited to increase the stability of the lower pressure plate 16 when it is lifted and lowered, and the lifting plate 8, the lower pressure plate 16 and the support plate 20 are limited by the limiting columns A31 and the limiting columns B32 to increase the stability of the lifting plate 8, the lower pressure plate 16 and the support plate 20 when they move, thereby preventing the components from shifting during the working process of the device and affecting the use.

[0045] like Figure 1 to Figure 2 As shown, a moving guide wheel 33 is fixedly installed at the bottom of the base plate 1, a side plate 34 is symmetrically fixedly installed at the top of the base plate 1, and handrails 35 are symmetrically fixedly installed on the inner walls of the two side plates 34; the sliding friction force is converted into rolling friction force by the moving guide wheel 33, and the handrail 35 is pushed to move the moving guide wheel 33, thereby facilitating the movement of the device.

[0046] Working principle: Place the positioning ring 3 used for positioning the photovoltaic pile foundation on the inner side of the discharge column 2, and then move the device to the construction position. After moving the device to the construction point, adjust the position of the base plate 1 so that the center of the base plate 1 is aligned with the construction point. When aligning, since the positioning hole 4 is opened in the center of the base plate 1, the positioning hole 4 can be aligned with the construction point. At the same time, the positioning hole 4 is used to facilitate observation of the alignment of the device, thereby facilitating positioning.

[0047] After the positioning is completed, the automatic telescopic rod 5 is started to retract the automatic telescopic rod 5. When the automatic telescopic rod 5 is retracted, the section connected to the lifting plate 8 will be retracted first. As the section of the automatic telescopic rod 5 connected to the lifting plate 8 is retracted, the lifting plate 8 will move downward. When the lifting plate 8 descends, the rotating plate 9 will rotate. As the rotating plate 9 rotates, the push roller 6 at one end thereof will be driven to move in the direction away from the lifting plate 8. When the push roller 6 moves, the force-bearing block 10 will be pushed to move, thereby driving the push plate 7 to move in the direction of the discharge column 2. When the push plate 7 extends into the discharge column 2, the positioning ring 3 at the bottom of the inner side of the discharge column 2 will be squeezed out. The extruded positioning ring 3 will enter the discharge box 11 and fall along the discharge box 11, thereby realizing the automatic discharge of the positioning ring 3. During material unloading, each positioning ring 3 is moved synchronously by the push plate 7 and falls through the unloading box 11 respectively, so as to ensure that each positioning ring 3 maintains the same distance with the positioning hole 4, thereby ensuring the construction accuracy of the subsequent photovoltaic pile foundation. When the positioning ring 3 is falling, the movement of the push plate 7 will drive the moving block 13 to move. When the moving block 13 moves, it will be limited by the limiting rod 14, thereby limiting the push plate 7 and making the push plate 7 move in a preset direction. As the push plate 7 moves, the moving block 13 squeezes the elastic member 15, so that the elastic member 15 is in a compressed state. When the positioning ring 3 is fixed, the automatic telescopic rod 5 is extended to make the push roller 6 retreat, and the push plate 7 will be reset under the action of the reverse elastic force of the elastic member 15, thereby preparing for the next work.

[0048] When the device completes the unloading work of the positioning ring 3, a section of the automatic telescopic rod 5 connected to the lifting plate 8 shrinks to the minimum value. At this time, the automatic telescopic rod 5 will continue to shrink, and the lifting plate 8 will no longer descend. The lower pressure plate 16 at one end of the automatic telescopic rod 5 will continue to descend. When the lower pressure plate 16 descends, it will drive the extension plate 17 to descend. When the extension plate 17 descends, it will drive the lower pressure head 19 to descend through the lower pressure column 18. Since the lower pressure head 19 is located above the unloading box 11, the lower pressure head 19 will pass through the unloading box 11 to squeeze the positioning ring 3 after it descends, so that the conical column at the bottom of the positioning ring 3 is inserted under the ground, thereby realizing automatic fixation of the positioning ring 3. After the positioning ring 3 is fixed, other components are inserted into the positioning ring 3, thereby forming the outer frame of the photovoltaic pile foundation, which is convenient for the subsequent construction of the photovoltaic pile foundation. Through the above scheme, rapid positioning before the construction of the photovoltaic pile foundation and rapid installation of the outer frame can be achieved, effectively improving work efficiency.

[0049] When the lifting plate 8 descends to perform unloading work, the lifting plate 8 will drive the support plate 20 to descend. When the support plate 20 descends, it will drive the support feet 22 to descend through the support legs 21. Before the positioning ring 3 falls, the support feet 22 will first contact the ground, thereby lifting the device. At this time, the moving guide wheel 33 no longer plays a role, thereby preventing the device from deviating during subsequent unloading and fixing work and increasing the overall stability of the device during operation, thereby ensuring the accuracy of positioning.
