Description

Technical Field

[0001] This invention relates to the field of photovoltaic installation positioning device technology, and in particular to a rapid positioning and measuring instrument for photovoltaic support foundations. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic power generation, as an important form of renewable energy, is rapidly expanding in scale. In the construction of large-scale photovoltaic power plants, the installation accuracy of photovoltaic support structures directly affects the installation efficiency of subsequent photovoltaic modules, power generation, and the operational safety of the entire power plant. Therefore, in the early stages of construction, rapid and accurate positioning and measurement of thousands of photovoltaic support foundations is a key step in ensuring project quality and progress.

[0003] Currently, traditional methods for positioning photovoltaic support foundations mainly rely on professional surveying equipment such as total stations and theodolites. Although these methods offer high accuracy, they require skilled personnel and involve significant labor costs. Secondly, the surveying and setting-out process is cumbersome, requiring point-by-point setup, centering, and leveling, resulting in low work efficiency and severely restricting the construction cycle of large-scale photovoltaic power plants. Furthermore, the measurement accuracy and stability of traditional optical instruments are significantly affected under complex terrain or adverse weather conditions.

[0004] Therefore, in order to achieve rapid positioning and marking of photovoltaic support structures, we propose a rapid positioning and measuring instrument for photovoltaic support structure foundations. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for professional measurement personnel to operate the equipment, high skill requirements, and large labor costs, and to propose a rapid positioning and measuring instrument for photovoltaic support foundations.

A wire spool is detachably connected to the outside of the wire-laying frame, wherein a steel cable is wound around the outside of the wire spool, and the other end of the steel cable is connected to the anchor rod. The calibration unit is slidably connected to the steel cable, and a distance measuring guide assembly is also fixedly installed on the side of the base.

[0007] Furthermore, the wire feeding frame includes; Rotate the turntable connected to the base; Four screws are rotatably connected to the end face of the turntable, and the ends of the four screws are driven by bevel gears.

[0010] Furthermore, the adjusting rod has several positioning holes on its side, and the base has a spring insert assembly on its side, with the end of the spring insert assembly inserted into the positioning holes.

[0011] Furthermore, the calibration unit includes; A guide tube is slidably connected to the outside of the steel cable, and a calibration rod is fixedly connected below the guide tube. A locking assembly is provided between the calibration rod and the steel cable.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-6As an embodiment of the present invention, a rapid positioning and measuring instrument for photovoltaic support foundation is disclosed. Specifically, the positioning and measuring instrument includes a wire laying unit 1, an anchor rod 2, and a calibration unit 3. Specifically, the anchor rod 2 described in the present invention is used to fix the free end of the steel cable 14 on the ground. The wire feeding unit 1 includes a base 11, and a wire feeding frame 12 is rotatably connected above the base 11. A wire spool 13 is detachably connected to the outside of the wire feeding frame 12. A steel cable 14 is wound around the outside of the wire spool 13, and the other end of the steel cable 14 is connected to the anchor rod 2. The calibration unit 3 is slidably connected to the steel cable 14, and a distance measuring guide assembly 15 is also fixedly installed on the side of the base 11.

[0021] In other words, by using anchor rod 2 to fix one end of steel cable 14 and tensioning it with the help of laying out unit 1, a high-precision physical baseline is established. The operator can use calibration unit 3 to slide on the baseline and cooperate with distance measuring guide component 15 to perform position detection. This enables efficient and accurate positioning of multiple photovoltaic bracket installation positions on a straight line. This greatly simplifies the traditional measurement and layout process, reduces the dependence on professional surveyors and instruments, and significantly improves the convenience and efficiency of positioning measurement.

[0022] In some embodiments, the wire feeding frame 12 of the present invention includes; Rotate the turntable 121 connected to the base 11; Four screws 122 are rotatably connected to the end face of the turntable 121. The ends of the four screws 122 are driven by bevel gears 123. Multiple slide blocks 124 are slidably connected above the turntable 121. The slide blocks 124 are threadedly connected to the screws 122. A clamping rod 125 is fixedly installed above the slide blocks 124.

[0023] Specifically, in this embodiment, when the wire spool 13 needs to be installed, it can be placed at the center of the turntable 121. Then, by rotating any one of the screws 122, under the transmission of the bevel gear 123, the four screws 122 will rotate synchronously, driving the four slides 124 to move radially toward the center, thereby driving the four clamping rods 125 to tension and fix the wire spool 13 from the inside. This design not only provides a firm clamping and ensures the stability of the wire feeding process, but also adapts to wire spools 13 with different inner diameters, making it highly versatile.

[0024] Of course, in order to achieve automatic drive of the screw 122, in this embodiment, a first motor 126 connected to a screw 122 is fixedly installed on the side of the turntable 121, and a second motor 16 is fixedly installed on the side of the base 11. The second motor 16 is driven by the turntable 121 through the gear ring assembly 17.

[0025] Optionally, the gear and gear ring assembly 17 described in this embodiment includes a gear fixedly mounted on the shaft end of the second motor 16, and a gear ring fixedly mounted below the turntable 121. The second motor 16 drives the gear to rotate, thereby driving the gear ring and the entire turntable 121 to rotate, thus realizing the automatic and controllable unwinding and rewinding of the steel cable 14.

[0026] In some embodiments, the ranging guide assembly 15 of the present invention includes; The adjusting rod 151 is movably attached to the side of the base 11; A rangefinder 152 is embedded at the end of the adjusting rod 151, and a vertical rod 153 is fixedly connected to the upper end of the adjusting rod 151. A guide sleeve 154 is fixedly installed above the vertical rod 153.

[0027] During operation, the steel cable 14 passes through the guide sleeve 154, which provides stable support and guidance for the steel cable 14, ensuring that it always remains in a straight line. When the calibration unit 3 slides on the steel cable 14, the rangefinder 152 can be a laser rangefinder, which achieves high-precision positioning and distance reading by detecting the relative position of the calibration unit 3 in real time. The adjustable design of the adjusting rod 151 allows the operator to easily adjust the position of the measuring point and the guide point according to the site conditions, enhancing the flexibility and applicability of the equipment.

[0028] In an optional embodiment, the adjusting rod 151 of the present invention has a plurality of positioning holes 155 on its side, and the base 11 has a spring insert rod assembly 156 on its side, the rod end of the spring insert rod assembly 156 being inserted into the positioning holes 155.

[0029] The spring rod assembly 156 includes a rod that is inserted into the base 11, and a spring connecting the base 11 and the rod. By inserting and locking the rod into the positioning hole 155, the insertion position of the adjusting rod 151 can be fixed, thereby improving the stability and reliability of the detection.

[0030] In some embodiments, the calibration unit 3 of the present invention includes; A guide tube 31 is slidably connected to the outside of the steel cable 14, and a calibration rod 32 is fixedly connected below the guide tube 31. A locking assembly is provided between the calibration rod 32 and the steel cable 14.

[0031] Specifically, in this embodiment of the invention, the locking assembly includes a sliding sleeve 33 that is slidably connected to the outside of the calibration rod 32. The sliding sleeve 33 and the calibration rod 32 are circumferentially locked, and a compression spring 34 is fixedly connected between the sliding sleeve 33 and the calibration rod 32. A clamping frame 35 is fixedly installed above the sliding sleeve 33, and the steel cable 14 is clamped between the clamping frame 35 and the calibration rod 32.

[0032] In its natural state, the elastic force of the compression spring 34 will push the sliding sleeve 33 to move. The steel cable 14 is movably connected between the clamping frame 35 and the calibration rod 32. At this time, the calibration unit 3 can move freely. When it moves to the predetermined position, the operator only needs to press down on the sliding sleeve 33, the clamping frame 35 moves down and clamps the steel cable 14, and the position of the calibration unit 3 can be locked.

[0033] In an optional embodiment, a material frame 36 is fixedly installed on the side of the calibration rod 32 of the present invention, a material discharge component 37 is provided at the bottom side of the material frame 36, and a transmission component 38 is provided between the material discharge component 37 and the sliding sleeve 33.

[0034] Specifically, in this embodiment, the discharge assembly 37 includes a feeding wheel 371 rotatably connected to the bottom opening of the material frame 36, and the outer side of the feeding wheel 371 has a material groove 372. A guide frame 373 is fixedly installed on the side of the calibration rod 32, and a discharge port 321 communicating with the guide frame 373 is opened at the bottom of the calibration rod 32.

[0035] Specifically, the present invention has a material frame 36 fixedly installed on the side of the calibration rod 32. The material frame 36 is used to hold the marking material, such as lime powder or pigment. When the operator presses down the sliding sleeve 33 to lock the calibration unit 3, the transmission component 38 will drive the feeding wheel 371 to rotate at a preset angle. At this time, the material trough 372 containing the marking material will rotate to the bottom opening, pour the marking material into the guide frame 373, and finally fall to the ground through the discharge port 321, forming a clear marking point. When the sliding sleeve 33 is released, the locking component unlocks and can slide freely. At the same time, the transmission component 38 drives the feeding wheel 371 to reset, and the next material trough 372 begins to be filled, preparing for the next marking.

[0036] This design cleverly combines the locking and marking actions into one, enabling marking while moving, which greatly simplifies the operation steps and significantly improves the efficiency of continuous positioning.

[0037] It should be noted that, in this embodiment of the invention, the transmission assembly 38 includes a drive rod 381 rotatably connected to the side of the sliding sleeve 33, and an ear plate 382 is fixedly installed on the shaft of the feeding wheel 371. The end of the drive rod 381 and the ear plate 382 are pin-connected.

[0038] Specifically, when the operator presses down on the sliding sleeve 33, the sliding sleeve 33 slides down along the calibration rod 32, causing the upper end of the drive rod 381 to move accordingly. Since the lower end of the drive rod 381 is pinned to the fixed ear plate 382, ​​the translational movement of the drive rod 381 will be converted into a pushing or pulling force on the ear plate 382, ​​thereby driving the shaft of the feeding wheel 371 to rotate, realizing the step-by-step rotation of the feeding wheel 371 and completing one discharge. When the sliding sleeve 33 is released, under the action of the compression spring 34, the sliding sleeve 33 returns to its original position, and the drive rod 381 drives the feeding wheel 371 to rotate in the opposite direction, restoring it to its initial standby position.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
