Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic foundation pile testing equipment, and in particular relates to a photovoltaic foundation pile static load testing device. Background Technology

[0002] Static load testing of photovoltaic (PV) foundation piles is a key testing technology for verifying the bearing capacity and deformation characteristics of PV pile foundations. Stable support is provided by reaction devices (anchor pile system / load platform / self-balancing device), and loads are applied in stages using hydraulic jacks (usually in stages of 1 / 10 of the estimated bearing capacity). The settlement displacement of the pile top and the real-time load value are measured simultaneously, and finally the characteristic value of the pile foundation bearing capacity is determined by PS curve analysis.

[0003] To ensure stable stress, conventional reaction devices need to be connected to at least two or more foundation piles to ensure that the reaction device can bear the stress normally. Therefore, two or more foundation piles need to be equipped with matching brackets for normal testing, which makes the conventional reaction device less practical for static load testing of photovoltaic foundation piles.

[0004] To address these issues, we propose a static load testing device for photovoltaic foundation piles. Utility Model Content

[0005] The purpose of this invention is to address the problem of the low practicality of conventional reaction force devices for static load testing of photovoltaic piles, and to propose a static load testing device for photovoltaic piles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A static load testing device for photovoltaic (PV) foundation piles includes a pressure sensor and a display. A base is fixedly connected to the lower end of the pressure sensor, and the pressure sensor is electrically connected to the display. A threaded post is fixedly connected to the pressure sensor, and a threaded disc is threaded onto the threaded post. A support sleeve is slidably fitted onto the threaded post, and a spring-loaded buckle is provided at the lower part of the support sleeve. The upper end of the spring-loaded buckle is fixedly connected to the support sleeve, and the spring-loaded buckle slidably engages with the threaded post. An elastic clamp is fixedly connected to the upper part of the support sleeve, and a screw is threaded onto the lower part of the elastic clamp. The elastic clamp is fitted onto the target PV foundation pile, and then the screw is tightened. The threaded disc is rotated upwards, causing the support sleeve to lift upwards through the threaded disc. The support sleeve then acts upwards on the elastic clamp, which in turn acts upwards on the target PV foundation pile. During this process, the pressure sensor's force data is observed on the display, facilitating static load testing of PV foundation piles and improving practicality.

[0007] Preferably, the threaded post includes a threaded post body, and a groove is formed on the outside of the threaded post body. The groove guides the sliding of the spring clip, preventing the support sleeve from falling off during transportation.

[0008] Preferably, the threaded disc includes a nut, and an operating disc is fixedly connected to the outside of the nut. The nut is threaded onto the threaded column. The operating disc increases the length of the operating lever, and manual operation of the operating disc drives the nut to rotate, causing the nut to spiral up and down along the threaded column, facilitating the lifting or lowering of the support sleeve.

[0009] Preferably, the support sleeve includes a sleeve body with a perforated lower portion. The sleeve body is slidably fitted onto a threaded post, and its lower end is in movable contact with a nut. The threaded post guides the sleeve body to slide and move up and down.

[0010] Preferably, the spring clip includes a spring piece, the lower end of which is fixedly connected to a clip block, and the upper end of which is fixedly connected to the sleeve body. The clip block is movably embedded in a sliding groove. The spring piece acts on the clip block, which slides along the sliding groove. The sliding groove limits the clip block, and the spring piece acts on the threaded column to prevent the threaded column from falling off.

[0011] Preferably, the elastic hoop includes a connecting plate, which is fixedly connected to the upper end of the sleeve. One end of the connecting plate is fixedly connected to the elastic hoop body, and the lower end of the elastic hoop body is fixedly connected to an installation ring. A screw is installed inside the installation ring. The elastic hoop body is fitted onto the target photovoltaic foundation pile, and then the screw is inserted into the installation ring and tightened. The screw tightens the installation ring, causing the installation ring to act on the elastic hoop body, thus tightening the elastic hoop body and facilitating its fixing or loosening.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Place the elastic hoop on the target photovoltaic pile, then tighten the screws and rotate the threaded disc upwards. The threaded disc will lift the support sleeve upwards, which will then act upwards on the elastic hoop, which in turn will act upwards on the target photovoltaic pile. During this process, observe the force data from the pressure sensor on the display to facilitate static load testing of the photovoltaic pile and improve its practicality.

[0013] 2. Increase the length of the operating lever by using the operating panel. Manually operate the operating panel to drive the nut to rotate, so that the nut can be spirally raised or lowered along the threaded column, making it convenient to lift or lower the support sleeve.

[0014] 3. Place the elastic hoop onto the target photovoltaic base pile, then insert the screw into the mounting ring and tighten the screw. By tightening the mounting ring with the screw, the mounting ring acts on the elastic hoop, tightening the elastic hoop, making it easy to fix or open the elastic hoop. Attached Figure Description
