[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] A wind turbine tower cleaning device (hereinafter referred to as the cleaning device), with reference to Figure 1 This includes a first mounting structure 10 assembled at the top of the tower 1 and a second mounting structure 20 assembled at the bottom of the tower 1. In some embodiments, refer to... Figure 1 and combined Figure 3 The first mounting structure 10 includes a first upper support ring 100 that can be fitted onto the outer wall of the tower 1. Correspondingly, the second mounting structure 20 includes a second upper support ring 200 that can be fitted onto the outer wall of the tower 1. Since the tower 1 has a tapered structure, that is, the cross-sectional area of ​​the tower 1 gradually increases from top to bottom, the annular structure design of the first upper support ring 100 and the second upper support ring 200 can be naturally clamped onto the tower 1, thereby reducing the difficulty of fixing the first mounting structure 10 and the second mounting structure 20 onto the tower 1 and the number of parts required for fixing.

[0019] Reference Figure 1 and combined Figure 3The aforementioned cleaning device further includes a first movable trolley 30 disposed on the upper surface of the first upper support ring 100 and a second movable trolley 31 disposed on the upper surface of the second upper support ring 200. The first movable trolley 30 is configured to move along the upper surface of the first upper support ring 100, and the second movable trolley 31 is configured to move along the upper surface of the second upper support ring 200. That is, both the first movable trolley 30 and the second movable trolley 31 are configured to move along the circumferential direction of the tower 1, in conjunction with the subsequent water pipes and the nozzles on the water pipes to achieve cleaning of the exterior of the tower 1. The wall surface is fully covered for cleaning. At the same time, the first moving trolley 30 and the second moving trolley 31 are both electrically driven, with the driving power source coming from the wind turbine itself. In some embodiments, the upper surfaces of the first upper support ring 100 and the second upper support ring 200 are provided with annular slide rails 203. Based on the design of the annular slide rails 203, the first moving trolley 30 and the second moving trolley 31 are limited and moved on the first upper support ring 100 and the second upper support ring 200, so as to avoid the first moving trolley 30 and the second moving trolley 31 from the annular slide rails 203.

[0020] Continue to refer to Figure 1 The cleaning device also includes a cleaning pipe 50, which is configured as, for example, a rubber pipe. One end (upper end) of the cleaning pipe 50 is connected to and closed by the first moving trolley 30, and the other end (lower end) is connected to the water injection pipe of the cleaning vehicle through a pipe clamp. The cleaning pipe 50 also has a connection point that is fixedly connected to the second moving trolley 31. In some examples, the cleaning pipe 50 is provided with multiple nozzles (not shown). The multiple nozzles are spaced apart along the length of the cleaning pipe 50 to achieve clear coverage in the height direction of the tower 1. During cleaning operation, the cleaning liquid enters the cleaning pipe 50 under the action of a high-lift centrifugal pump in the cleaning vehicle and is sprayed onto the outer wall of the tower 1 through the nozzles on the cleaning pipe 50 to achieve the cleaning operation of the tower 1.

[0021] In some embodiments, refer to Figure 1 and combined Figure 2 The first mobile trolley 30 is also equipped with a wire feeding motor 40. Correspondingly, the upper end of the cleaning tube 50 is connected to the output end of the wire feeding motor 40, thereby simplifying the installation and fixing of the cleaning tube 50. For example, the upper end of the cleaning tube 50 is threadedly connected to the end of the cable of the wire feeding motor 40, that is, the end of the cable of the wire feeding motor 40 is equipped with a threaded sleeve to achieve the sealing of the upper end of the cleaning tube 50 and the connection between the cleaning tube 50 and the wire feeding motor 40. At this time, when it is necessary to replace or repair the cleaning tube 50 during operation, the wire feeding motor 40 can be controlled to rotate to place the cleaning tube 50 on the ground, which is convenient for maintenance personnel to replace or repair on the ground. After the hose is replaced or repaired, the wire feeding motor 40 is controlled to rotate in the opposite direction to pull the upper end of the cleaning tube 50 back to the position of the first mobile trolley 30.

[0022] In some embodiments, refer to Figure 3 and combined Figure 4 The first mounting structure 10 further includes a first lower support ring 102 and a first support frame 101. Correspondingly, the second mounting structure 20 also includes a second lower support ring 202 and a second support frame 201. Specifically, the first lower support ring 102 is disposed below the first upper support ring 100, and the inner diameter of the first lower support ring 102 is larger than the inner diameter of the first upper support ring 100. At the same time, the first upper support ring 100 and the first lower support ring 102 are connected by the first support frame 101 to form a frustum-shaped first mounting structure that is narrower at the top and wider at the bottom. 10. Correspondingly, the second upper support ring 200 and the second lower support ring 202 are connected by the second support frame 201, and the inner diameter of the second lower support ring 202 is larger than the inner diameter of the second upper support ring 200. At the same time, the second upper support ring 200 and the second lower support ring 202 are connected by the second support frame 201 to form a frustum-shaped second mounting structure 20 that is narrow at the top and wide at the bottom. In some embodiments, the first support frame 101 and the second support frame 201 are both composed of a plurality of X-shaped brackets 204 continuously arranged along the circumferential direction of the tower 1.
