[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a dynamic signal testing and analysis system for wind turbine blade strain data acquisition, including a housing 1, a switch 2 installed on the surface of the housing 1, sixteen connection channels 3 installed on the surface of the housing 1, a shielding device 4 provided on the surface of the housing 1, and a protective device 5 provided on the surface of the housing 1.

[0032] The specific settings and functions of the shielding device 4 and the protective device 5 will be explained in detail below.

[0033] Reference Figures 1-4 As shown, in this embodiment: the shielding device 4 includes two first shielding plates 401, both of which are slidably connected to the surface of the housing 1. Two second shielding plates 402 are slidably connected to the surface of the housing 1. A first insert plate 403 is fixedly connected to the side of each of the two second shielding plates 402 closest to the first shielding plate 401. The first insert plate 403 is slidably connected to the inner wall of the first shielding plate 401. A second insert plate 404 is fixedly connected to the side of each of the two second shielding plates 402 closest to the first shielding plate 401. The second insert plate 404 is slidably connected to the inner wall of the first shielding plate 401. By setting the first shielding plates 401 and the second shielding plates 402, the switch 2 and the connecting channel 3 on the housing 1 can be effectively sealed. By setting the first insert plates 403 and the second insert plates 404, the sealing effect of the first shielding plates 401 and the second shielding plates 402 can be improved. Adjusting plates 411 are fixedly connected to the sides of both first baffles 401 and second baffles 402. A bidirectional screw 410 is threaded into the inner wall of each adjusting plate 411. By using the bidirectional screw 410, the adjusting plate 411 can be moved, thus allowing for position adjustment of the first baffles 401 and second baffles 402.

[0034] A second connecting rod 409 is fitted onto the surface of a bidirectional screw 410. The bidirectional screw 410 is rotatably connected to the inner wall of the second connecting rod 409, which is fixedly connected to the side of the housing 1. A second limiting plate 412 is fixedly connected to one end of the bidirectional screw 410. By setting the second connecting rod 409, the bidirectional screw 410 can be connected to the housing 1 without affecting its rotation. Slide plates 407 are fixedly connected to the sides of the two first baffles 401 and the second baffle 402 away from the adjusting plate 411. A slide rod 406 is slidably connected to the inner wall of the slide plate 407. By setting the slide rod 406 and the slide plate 407, the stability of the movement of the first baffles 401 and the second baffle 402 can be improved. A first connecting rod 405 is fixedly connected to the surface of the slide rod 406, which is fixedly connected to the side of the housing 1. A first limiting plate 408 is fixedly connected to both ends of the slide rod 406. By setting the first connecting rod 405, the slide rod 406 can be connected to the housing 1.

[0035] Reference Figure 1 and Figure 2 as well as Figure 5 As shown, specifically, the protective device 5 includes four side plates 52, all of which are installed on the sides of the housing 1. A first damper 53 is fixedly connected to the side of each side plate 52 away from the housing 1, and a first buffer plate 54 is fixedly connected to the other end of each first damper 53. By setting the side plates 52, the first damper 53 and the first buffer plate 54 can be connected to the housing 1. The side plates 52, first dampers 53, and first buffer plates 54 provide protection for the housing 1. Four "L"-shaped plates 51 are fixedly connected to the sides of the housing 1, and the four side plates 52 are fixedly connected to the "L"-shaped plates 51. An arc-shaped plate 55 is fixedly connected to the side of the first buffer plate 54 away from the housing 1. By setting the "L"-shaped plates 51, the side plates 52 can be connected to the housing 1, and the arc-shaped plate 55 can be installed using the first buffer plate 54.

[0036] A second damper 56 is fixedly connected to the side of the arc-shaped plate 55 away from the first damper 53, and a second buffer plate 57 is fixedly connected to the other end of the second damper 56. By setting the arc-shaped plate 55, the second damper 56 and the second buffer plate 57 can be installed, and the protective effect can be improved by setting the second buffer plate 57 and the second damper 56.

[0037] Working principle: When the dynamic signal testing and analysis system is not needed, the bidirectional screw 410 is rotated to make it rotate on the inner wall of the second connecting rod 409. At this time, under the restriction of the slide plate 407, the slide rod 406 and the first connecting rod 405, the two adjusting plates 411 respectively drive the first blocking plate 401 and the second blocking plate 402 to move closer to each other, so that the first insert plate 403 and the second insert plate 404 are engaged in the inner wall of the first blocking plate 401. At this time, the first blocking plate 401 and the second blocking plate 402 can provide a shielding effect for the switch 2 and the connecting channel 3 on the housing 1. By setting the first limiting plate 408 and the second limiting plate 412, the stable connection between the slide plate 407, the adjusting plate 411, the slide rod 406 and the bidirectional screw 410 can be guaranteed. By setting the shielding device 4, the connecting channel 3 of the dynamic signal testing and analysis system can be sealed and shielded when the dynamic signal testing and analysis system is not in use, thereby minimizing the possibility of damage to the dynamic signal testing and analysis system due to water contact.

[0038] When the dynamic signal testing and analysis system is bumped or dropped, the impact on the second buffer plate 57 and the arc plate 55 will be absorbed by the second buffer plate 57, the second damper 56, the first buffer plate 54, and the first damper 53, thereby minimizing the damage to the dynamic signal testing and analysis system caused by the collision. By setting the "L"-shaped plate 51 and the side plate 52, the first damper 53 and the first buffer plate 54 can be connected to the dynamic signal testing and analysis system. By setting the protective device 5, the impact of the collision or drop on the dynamic signal testing and analysis system can be minimized as much as possible, thereby protecting the dynamic signal testing and analysis system.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
