[0019] The following is combined with Figure 1-2 The technical solution of the utility model is further illustrated by specific implementation methods.

[0020] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] A fatigue testing device for a photovoltaic tracking system, comprising a locking seat 1, a lever 2, a tension and compression driver 3 and a support seat 5;

[0023] The locking seat 1 and the supporting seat 5 are arranged at intervals and installed on the detection platform 10; the tension and compression driver 3 is installed close to the side of the detection platform 10;

[0024] The locking seat 1 is used to be mounted on one end of the main beam 6 to be tested; the supporting seat 5 is used to be movably mounted on the middle part of the main beam 6 to be tested; one end of the lever 2 is used to be connected to the other end of the main beam 6 to be tested; the other end of the lever 2 extends in the horizontal direction and is connected to the output end of the upward tension and compression driver 3.

[0025] like Figure 1-2 As shown, when using the fatigue testing device for a photovoltaic tracking system of the utility model, one end of the main beam 6 to be tested is locked in the locking seat 1, and the other end of the main beam 6 to be tested is connected to one end of a lever 2 extending in a horizontal direction after passing through the support seat 5, and then the output end of the tension and compression driver 3 extending upward is connected to the other end of the lever 2, and then a load is applied to the main beam 6 to be tested between the locking seat 1 and the support seat 5, and then the tension and compression driver 3 is started, so that the tension and compression driver 3 outputs a reciprocating push-pull force to the other end of the lever 2 according to the set torque and rhythm, so that the main beam 6 to be tested can be fatigue tested under load.

[0026] Furthermore, it also includes a tension pressure sensor 4;

[0027] The tension and pressure sensor 4 is installed below the tension and pressure driver 3 .

[0028] like Figure 1-2 As shown, the tension and pressure sensor 4 can obtain the torque output when the tension and pressure driver 3 pushes the main beam 6 to be detected upward, the force fed back by the main beam 6 to be detected when the tension and pressure driver 3 pulls downward, and the number of times the tension and pressure is reciprocated.

[0029] Further, it also includes a bearing;

[0030] The outer ring of the bearing is fixedly installed in the support seat 5, and the inner ring of the bearing is used to be sleeved on the middle part of the main beam 6 to be tested.

[0031] By supporting the middle part of the main beam 6 to be tested by a bearing, it is possible to avoid the fatigue test result being affected by excessive friction between the support seat 5 and the outer peripheral surface of the main beam 6 to be tested.

[0032] Preferably, the tension and compression driver 3 is an electric hydraulic cylinder.

[0033] Electric hydraulic cylinders have the advantages of high stroke accuracy and stable performance.

[0034] Preferably, the extension direction of the output end of the tension-compression driver 3 is perpendicular to the extension direction of the main beam 6 to be detected.

[0035] Keeping the extension direction of the output end of the tension-compression driver 3 perpendicular to the extension direction of the main beam 6 to be tested can avoid the loss of torque output by the tension-compression driver 3 and improve the data accuracy of the fatigue test.

[0036] In summary, if Figure 1-2 In the embodiment of the utility model shown, the fatigue testing device for the photovoltaic tracking system performs fatigue testing by outputting reciprocating tension and pressure to one end of the main beam 6 to be tested by the tension and pressure driver 4, and has a simple structure and is easy to operate.
