Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to a photovoltaic power generation PHC pipe pile foundation construction precision control instrument and its usage method. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy.

[0003] The flat single-axis tracking bracket is an advanced solar photovoltaic panel installation system that can automatically adjust the angle of the photovoltaic panel to maximize solar energy absorption.

[0004] The foundation of a single-axis tracking support is generally a pipe pile foundation. Several pipe pile foundations are part of the single-axis tracking support, and their performance directly affects the overall performance of the single-axis tracking support. Among them, PHC pipe pile foundations are widely used because of their reliable quality, strong applicability, and high degree of mechanized construction.

[0005] The accuracy requirements for the construction of several PHC pipe pile foundations are very strict. The deviation of the pipe pile position axis is within ±10mm, the deviation of the pipe pile spacing is within ±20mm, and the error of the pipe pile top elevation is within ±20mm. Furthermore, the cumulative deviation of the PHC pipe piles in the same direction is not allowed.

[0006] To achieve the installation accuracy required for single-axis tracking supports during PHC pipe pile foundation construction, existing methods of precision control and adjustment using manual labor combined with machinery, theodolites, total stations, and other surveying tools all have the following shortcomings:

[0007] 1. It is not convenient and quick to find the centerline, parallel line of the axis, and top horizontal line of several PHC pipe piles; the operation is inflexible and inconvenient.

[0008] 2. It is impossible to eliminate the obstruction of mechanical equipment on the pile position axis, pile spacing, and pile elevation deviation during PHC pipe pile construction;

[0009] 3. When constructing multiple PHC pipe piles, it is impossible to eliminate the need for multiple measurement tools at multiple angles, and it is impossible to save the need for multiple string line control operations. It is also impossible to minimize the time spent on mechanical and manual operations, making it difficult to improve efficiency, save energy, and reduce costs. Summary of the Invention

[0010] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a photovoltaic power generation PHC pipe pile foundation construction precision control instrument and its usage method.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A photovoltaic power generation PHC pipe pile foundation construction precision control instrument includes two fixed plates placed on the first and last PHC pipe piles respectively; a fixing component set on the fixed plate for fixing the fixed plate to the PHC pipe pile after it is placed on the PHC pipe pile; a control arm set on the fixed plate for adjusting to a predetermined position on the fixed plate after the fixing component fixes the fixed plate to the PHC pipe pile; a positioning connector set between the control arm and the fixed plate for positioning when the control arm is adjusted to the predetermined position on the fixed plate and for fixing the control arm after it is adjusted to the predetermined position on the fixed plate; a self-locking winch set on the control arm and located outside the fixed plate for following the control arm; and a connecting rope connecting the two self-locking winches.

[0013] A further improvement is that the fixing component includes several fixing holes formed on the fixing plate and arranged around the center of the fixing plate, and fixing bolts connected to the fixing holes for connecting with the PHC pipe pile and fixing the fixing plate to the PHC pipe pile.

[0014] A further improvement is that the positioning connector includes several positioning holes formed on the fixed plate and arranged around the center of the fixed plate, a positioning groove formed on the control arm for cooperating with the positioning holes, a positioning bolt connecting the positioning holes and the positioning groove, a connecting hole formed at the center of the fixed plate, and a connecting bolt connected to the connecting hole for fixing the control arm after the control arm is adjusted to a predetermined position on the fixed plate.

[0015] A further improvement is that the self-locking winch includes a winch frame disposed on the control arm and located outside the fixed plate, a rotating shaft rotatably disposed on the winch frame, a limiting clip disposed on the rotating shaft for limiting the connecting rope, a drive handle disposed on the rotating shaft for driving the rotating shaft to rotate, and a self-locking device disposed between the rotating shaft and the winch frame.

[0016] A further improvement is that the self-locking device is a ratchet mechanism located between the rotating shaft and the winch frame.

[0017] A further improvement is that the connecting rope is a steel wire rope.

[0018] Based on the same inventive concept, this invention also provides a method for using a photovoltaic power generation PHC pipe pile foundation construction precision control instrument: two fixed plates are placed on the first and last PHC pipe piles respectively. After the fixed plates are placed on the PHC pipe piles, the fixing components fix the fixed plates to the PHC pipe piles. After the fixing components fix the fixed plates to the PHC pipe piles, the control arm can be adjusted to a predetermined position on the fixed plate. When the control arm is adjusted to the predetermined position on the fixed plate, the positioning connector plays a positioning role, and after the control arm is adjusted to the predetermined position on the fixed plate, the control arm is fixed. The self-locking winch follows the control arm, and operating the self-locking winch enables... The connecting rope is tightened until it coincides with the axis of the first and last PHC pipe piles. The positions of other pipe piles are measured and located. A plumb bob is used to mark the center of the pipe pile position on the ground. The self-locking winch is operated to tighten the connecting rope until it is parallel to the upper axis of the first and last PHC pipe piles. The connecting rope is then tangent to the calculated elevation position of the top of the pipe pile under construction. A mark is made at the position where the connecting rope intersects perpendicularly. Then, the drilling machine is used to guide the hole, and the pipe pile is driven down using a vibrating puller. During the vibration and sinking process, the guide observes to ensure that the calculated elevation position of the top of the sinking pipe pile is tangent to the connecting rope, thus completing the pipe pile construction.

[0019] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0020] 1. It can conveniently and quickly locate the centerline, parallel line of the centerline, and top horizontal line of several PHC pipe piles, and the operation is flexible and convenient;

[0021] 2. It can eliminate the obstruction of mechanical equipment on the pile position axis, pile spacing, and pile elevation deviation during PHC pipe pile construction;

[0022] 3. When constructing multiple PHC pipe piles, the need for multiple measurement tools at multiple angles can be eliminated, and multiple string line control operations can be saved. This can minimize the time spent on mechanical and manual operations, thereby improving efficiency, saving energy, and reducing costs. Attached Figure Description

[0034] A photovoltaic power generation PHC pipe pile foundation construction precision control instrument includes two fixed plates 2 placed on the first and last PHC pipe piles 1 respectively; a fixing component on the fixed plate 2 for fixing the fixed plate 2 to the PHC pipe pile 1 after it is placed on the PHC pipe pile 1; a control arm 3 on the fixed plate 2 for adjusting to a predetermined position on the fixed plate 2 after the fixing component has fixed the fixed plate 2 to the PHC pipe pile 1; a positioning connector between the control arm 3 and the fixed plate 2 for positioning the control arm 3 when it is adjusted to the predetermined position on the fixed plate 2 and for fixing the control arm 3 after it is adjusted to the predetermined position on the fixed plate 2; a self-locking winch on the control arm 3 and located outside the fixed plate 2 for following the control arm 3; and a connecting rope 4 connecting the two self-locking winches. The connecting rope 4 is a steel wire rope.

[0035] The fastener includes several fixing holes 5 formed on the fixing plate 2 and arranged around the center of the fixing plate 2, and fixing bolts 6 connected to the fixing holes 5 for connecting with the PHC pipe pile 1 and fixing the fixing plate 2 to the PHC pipe pile 1.

The self-locking device 16 is a ratchet mechanism located between the rotating shaft 13 and the winch frame 12.

[0038] How to use the photovoltaic power generation PHC pipe pile foundation construction precision control instrument: Two fixing plates 2 are placed on the first and last PHC pipe piles 1 respectively. After the fixing plates 2 are placed on the PHC pipe piles 1, the fixing holes 5 and fixing bolts 6 are used to fix the fixing plates 2 to the PHC pipe piles 1. After the fixing components fix the fixing plates 2 to the PHC pipe piles 1, the control arm 3 can be adjusted to the predetermined position on the fixing plates 2. When the control arm 3 is adjusted to the predetermined position on the fixing plates 2, the positioning holes 7, positioning grooves 8, and positioning bolts 9 cooperate to perform a positioning function. After the control arm 3 is adjusted to the predetermined position on the fixing plates 2, the connecting holes 10 and connecting bolts 11 are used to fix the control arm 3, which is self-locking. The control arm 3 is followed by the operation of the self-locking winch to tighten the connecting rope 4. After the connecting rope 4 is tightened, it is aligned with the axis connection line of the first and last PHC pipe piles 1. The positions of other pipe piles are measured and located. A plumb bob is used to mark the center of the pipe pile position on the ground. The self-locking winch is operated to tighten the connecting rope 4. After the connecting rope 4 is tightened, it is parallel to the upper axis of the first and last PHC pipe piles 1, so that the connecting rope 4 is tangent to the calculated elevation position of the top of the pipe pile under construction. The position where it intersects perpendicularly with the connecting rope 4 is marked. Then, the drilling machine is used to guide the hole, and the pipe pile is vibrated and driven down by the extraction machine. During the vibration and sinking of the pipe pile, the guide observes and ensures that the calculated elevation position of the top of the sinking pipe pile is tangent to the connecting rope 4, thus completing the pipe pile construction.
