[0025] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0026] In the present disclosure, "inner and outer" refer to the inner and outer of the profile of the corresponding components, and in addition, the terms "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance, and in addition, the following description refers to the drawings, and unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] According to Figure 1 and Figure 2 , the first aspect of the present disclosure provides a fixing structure of a wind turbine control device, for clamping and fixing the wind turbine control device. The control device can include a plurality of digital modules 100 arranged along a first direction X, and adjacent two digital modules 100 are electrically connected by a conductive track 110. The fixing structure can include a driving member 210 and two fixing members 200, the two fixing members 200 are arranged at intervals in the first direction X and located at opposite sides of the control device, and the driving member 210 is drivingly connected to at least one fixing member 200 along the first direction X, so that the two fixing members 200 can be close to each other and clamp the plurality of digital modules 100.

[0028] Through the above technical solution, two fixing members 200 are arranged on opposite sides of the control device along the first direction X, so that the multiple digital modules 100 are located between the two fixing members 200. By providing a driving member 210, at least one fixing member 200 can be moved along the first direction X under the drive of the driving member 210, so that the operator can adjust the distance between the two fixing members 200 according to actual needs, and further clamp and stabilize the multiple digital modules 100 by driving the fixing members 200, so that the connection between two adjacent digital modules 100 is more stable and can be adapted to control devices of different sizes, with better adaptability. Therefore, the fixing structure provided by the present disclosure can further stabilize the multiple digital modules 100 and have greater reliability and safety in use.

[0029] The conductive rail 110 can be constructed as a protrusion and arranged on one side of the digital module 100 along the first direction X. A groove that cooperates with the conductive rail 110 is provided on the other side. The material inside the groove can be the same as that of the conductive rail 110 to achieve the conductive function.

[0030] It should be noted that, regarding the specific structure of the control device and the specific connection relationship between each digital module 100, those skilled in the art may refer to the existing Beckhoff controller, which will not be elaborated herein.

[0031] In some embodiments, for example, referring to Figure 1 As shown, the fixing member 200 may include a fixing plate 201, which may have a through hole. The driving member 210 may include a connecting rod 211, with both ends of the connecting rod 211 respectively inserted into the through holes of the two fixing plates 201. The fixing plate 201 may be connected to the connecting rod 211 via a locking member 220. In this manner, the fixing plate 201 can move along the extension direction of the connecting rod 211 and can be locked and connected to any position of the connecting rod 211 via the locking member 220. This allows the distance between the two fixing plates 201 to be arbitrarily adjusted to accommodate fixing devices of different sizes. This also allows for clamping and fixing multiple digital modules 100, providing greater flexibility in use.

[0032] The structures of the connecting rod 211 and the locking member 220 can be adaptively adjusted according to the needs of actual conditions. For example, the connecting rod 211 can be constructed as a threaded rod, and the locking member 220 can be constructed as a nut, or the connecting rod 211 can be constructed as a round rod, and the locking member 220 can be constructed as two mutually cooperating sleeves, and the two sleeves can together form a through hole for the round rod to pass through, and the two sleeves can be locked and fixedly connected to the round rod by connecting bolts.

[0033] The number of locking members 220 can be adjusted according to actual needs, for example, in order to further enhance stability, the fixing plate 201 can be provided with nuts on the opposite sides in the first direction X, so that the number of nuts on each threaded rod can be four. Of course, when one side of the fixing plate 201 abuts against the control device, the nuts can also be arranged only on the side of the fixing plate 201 away from the control device, so that the number of nuts on each threaded rod can be two. The present disclosure does not make specific limitations in this regard.

[0034] In some implementable manners, for example, as shown in Figure 1 The number of through holes and connecting rods 211 can be multiple, the multiple through holes are arranged on the fixing plate 201 in intervals, and the multiple connecting rods 211 correspond to the multiple through holes one by one. By arranging multiple through holes and connecting rods 211, the stability of the fixing structure can be further enhanced, so that the fixing of the control device is more stable.

[0035] Optionally, the number of through holes can be four, the four through holes are arranged in pairs, and arranged in intervals along the fixing plate 201 in the second direction Y, the two through holes in each pair are arranged in intervals along the fixing plate 201 in the first direction X, and the control device is located between the two through holes.

[0036] Of course, the number of through holes can also be six, the six through holes are arranged in pairs, and arranged in intervals along the fixing plate 201 in the second direction Y, the two through holes in each pair are arranged in intervals along the fixing plate 201 in the first direction X, and the control device is located between the two through holes. The present disclosure does not make specific limitations in this regard, and the number of through holes can also be five, and those skilled in the art can make adaptive adjustments according to actual needs.

[0037] Among them, the second direction Y can be a direction perpendicular to the first direction X.

[0038] In some implementable manners, the contact surface of the fixing plate 201 in contact with the digital module 100 can also be provided with a buffer pad 230 to increase the friction between the digital module 100 and the fixing plate 201, and to reduce the stress applied by the fixing plate 201 to the digital module 100, thereby avoiding damage to the digital module 100.

[0039] The buffer pad 230 can be constructed in any suitable manner, for example, the buffer pad 230 can be a shock-absorbing and anti-skid silica gel pad. The present disclosure does not make specific limitations in this regard.

[0040] Among them, the two fixing plates 201 can be provided with buffer pads 230, or one of the fixing plates 201 is provided with a buffer pad 230, and the other fixing plate 201 is not provided with a buffer pad 230. The present disclosure is not limited to this.

The mating portion 250 may be movably connected to the mounting portion 240 so that the fixing plate 201 can move along the first direction X. The other fixing plate 201 may be fixedly connected to the wall 300, or the other fixing plate 201 may be fixedly connected to the connecting rod 211. The movably connected mating portion 250 and the mounting portion 240 facilitate adjustment of the relative distance between the two fixing members 200, and the stability may be further improved by fixedly connecting the other fixing plate 201 to the wall 300 or the connecting rod 211.

[0042] The mounting portion 240 and the mating portion 250 may be constructed in any suitable manner. For example, the mounting portion 240 may be constructed as a slide rail extending along the first direction X, and the mating portion 250 may be constructed as a slider, or the mating portion 250 may be constructed as a pulley. This disclosure does not impose any specific limitations on this.
