Description

Technical Field

[0001] This utility model relates to the technical field of electric actuator testing equipment, and in particular to a photovoltaic electric actuator load capacity testing device. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic power generation systems are increasingly widely used in various scenarios. As a key actuator in photovoltaic power generation systems, the performance of the photovoltaic actuator directly affects the stability and efficiency of the entire system. Especially in automatic tracking photovoltaic systems, the actuator needs to frequently adjust the angle of the photovoltaic panels to maximize solar radiation reception, thus placing higher demands on load capacity, durability, and reliability. Currently, the existing method involves installing the actuator onto the photovoltaic support structure and then activating it to test the load current. The drawback is that this testing method is cumbersome and requires on-site data collection at the photovoltaic support structure.

[0003] A search revealed a Chinese utility model patent (authorization announcement number: CN209432425U) that provides a load testing machine for a linear push rod, including a test channel structure, a control box, and a frame. The control box is mounted on the frame. The test channel structure includes an upper connecting component, a lower connecting component, a test guide rail, and a load cylinder. The test guide rail is fixed to the frame. The upper and lower connecting components are mounted on the outer surface of the test guide rail, and the upper and lower connecting components are arranged opposite each other to form a channel for clamping the linear push rod. The load cylinder is mounted on the inner surface of the guide rail and connected to the upper connecting component.

[0004] The advantages of the above-mentioned prior art are as follows: by setting a test channel structure on the frame, fixing the linear push rod between the upper connecting part and the lower connecting part, and then inputting the set maximum load of the linear push rod into the load cylinder, the upper connecting part presses down the linear push rod according to the set value. If the linear push rod is not damaged, the load test is passed.

[0005] The shortcomings of the existing technology are that it can only measure the maximum load capacity of the push rod under normal conditions, but cannot simulate the test results under various environments, and cannot test the load current of the push rod during testing. Therefore, it is urgent to improve this shortcoming. Utility Model Content
