Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment monitoring technology, and more specifically, to a simple device for monitoring the tilt of photovoltaic supports. Background Technology

[0002] As the core structure supporting a photovoltaic (PV) system, the levelness of the photovoltaic bracket directly affects the power generation efficiency and lifespan of the system. If the bracket is tilted, the angle of sunlight received by the system will deviate from the optimal value, and it may also cause stress concentration and deformation of the frame. Currently, commonly used monitoring methods in the industry have significant problems, such as relying on tools like levels and total stations, requiring on-site operation by staff, which is inefficient and costly. Utility Model Content

[0003] This invention aims to overcome the problems of low efficiency and high cost caused by relying on tools such as levels and total stations, which require on-site operation by staff. It provides a technical solution that can solve the above problems.

[0004] A simple device for monitoring the tilt of a photovoltaic support includes a fixing mechanism, a monitoring mechanism, and an marking mechanism. The fixing mechanism includes a fixing base and fastening bolts. The fixing base is an L-shaped metal plate with a mounting groove on its horizontal plate and bolt holes on its vertical plate. It is detachably connected to the support beam via fastening bolts. The monitoring mechanism includes a transparent shell sphere, a filling fluid, a circular float, and a rotating shaft. The transparent shell sphere is a hollow, sealed structure, and its top mates with the mounting groove of the fixing base, tilting synchronously with the support beam. The filling fluid fills the interior of the transparent shell sphere, with a filling volume of 1 / 3 of the sphere's internal volume. 2. A circular float floats on the surface of the filling fluid. A compass is embedded in the center of the upper surface of the circular float. The rotation axis is vertically fixed to the center of the lower surface of the circular float, and its lower end is connected to the center of the inner bottom of the transparent shell sphere, so that the circular float can rotate around the rotation axis. The marking mechanism includes an skew scale line and a baseline. The skew scale line is set on the outer circumference of the transparent shell sphere, with the vertical axis of the sphere as the 0° reference, and marks are made to both sides to a preset angle. The baseline line is set on the upper surface of the circular float, along the "north-south" direction of the compass. The midpoint of the baseline line coincides with the center of the circular float and is used to point to the skew scale line.

[0005] Furthermore, a boss is fixedly provided at the bottom of the circular float, and a through hole is provided at the bottom of the boss. An internal thread is provided in the through hole, and an external thread is provided on the outer surface of the upper end of the rotating shaft. The upper end of the rotating shaft is screwed to the boss through the thread, and after tightening, the rotating shaft remains perpendicular to the circular float.

[0006] Furthermore, it also includes a bearing, with the outer ring of the bearing fixedly located at the bottom center inside the transparent shell ball, and the rotating shaft being a thin stainless steel shaft, with the lower end of the rotating shaft fixedly located on the inner ring of the bearing.

[0007] Furthermore, it also includes a fixing plate. The top of the circular float has a groove, and the compass is embedded in the groove. The fixing plate is set on the top edge of the groove. The fixing plate is an L-shaped plate, and the compass is stuck at the bottom of the fixing plate.

[0008] Furthermore, the mounting base is made of 304 stainless steel, and the vertical plate has four bolt holes.

[0009] Furthermore, the filling fluid is an aqueous solution of ethylene glycol, which is non-corrosive to the material of the transparent shell spheres.

[0010] Furthermore, the skewed scale lines are printed on the lower middle part of the outer circumference of the transparent shell sphere. The preset angle of the skewed scale lines is 15°, the scale interval is 0.5°, and the angle value is marked at the whole degree scale.

[0011] Furthermore, the baseline is a straight line with a length consistent with the diameter of the circular float.

[0012] Furthermore, the transparent shell ball is made of polycarbonate, and the transparent shell ball and the mounting groove are interference fit.

[0013] Furthermore, the fixing base and the transparent shell ball are fixed together with epoxy resin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Compared to existing technologies, this utility model's simple device for monitoring photovoltaic bracket tilt utilizes a miniature compass on a circular floating plate to clearly define geographical direction. Combined with the relative position of the baseline and the scale, it can directly determine the tilt direction, eliminating the need for multiple readings and direction calculations required by manual measurement methods, thus avoiding operational errors. Furthermore, workers do not need to carry tools such as levels or total stations; they only need to stand on the ground and observe at eye level for 3-5 seconds to complete the tilt monitoring of a single bracket. Compared to manual measurement methods, inspection efficiency is significantly improved. The device uses detachable bolt connections, requiring only three steps for installation: attaching the fixing base to the bracket, tightening the bolts, and checking if the baseline aligns with the 0° scale. Ordinary maintenance personnel can complete this using a standard wrench, eliminating the need for professional wiring connections and parameter adjustments required for electronic devices. This improves installation efficiency, and the absence of exposed wiring after installation reduces the workload of subsequent wiring maintenance and lowers costs. Attached Figure Description
