Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This application provides a convenient flushing and cleaning system for wind turbine towers, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0036] See Figures 1 to 3 In one embodiment, the wind turbine tower convenient flushing and cleaning system includes: several layers of cleaning rings 2, a water supply pipe 3, a second pipe joint 4, a throttle valve 5, a water pump 6, a water tank 7, and a transport vehicle 8; wherein the cleaning rings 2 are used to be installed on the outer wall of the tower 1; adjacent layers of cleaning rings 2 are connected by the water supply pipe 3, and each cleaning ring 2 is provided with a nozzle 22 for flushing the tower 1; the water tank 7 is transported by the transport vehicle 8, and the water tank 7 supplies water to the cleaning rings 2 in sequence through the water pump 6, the throttle valve 5, the second pipe joint 4, and the water supply pipe 3.

[0037] In this embodiment, several layers of cleaning rings 2 can be pre-installed on the outer wall of the tower 1, and the diameter of each layer of cleaning rings 2 is adapted to the outer diameter of the tower 1 at the location; adjacent layers of cleaning rings 2 are connected by water supply pipes 3, and water pump 6 can supply water to the lowest layer of cleaning rings 2 through water supply pipes 3, thereby supplying water to each layer of cleaning rings 2 in sequence.

[0038] Furthermore, the cleaning ring 2 includes: an upper flushing ring 201 on which the nozzle 22 is disposed; a lower support ring 202 for being sleeved on the outer wall of the tower 1; and a plurality of support tubes 25; the lower end of the support tube is fixed on the lower support ring 202, and the upper end is used to support the upper flushing ring 201.

[0039] For details, see Figure 2 and Figure 4 The upper flushing ring 201 includes two symmetrically arranged semi-circular water pipes 21; the semi-circular water pipes 21 are hollow pipes, one end of the semi-circular water pipe 21 is a closed end and the other end is an open end; the open end of one semi-circular water pipe 21 is connected to the open end of the other semi-circular water pipe 21 through a cross joint 24.

[0040] In some embodiments, the upper and lower, left and right connectors of the cross connector 24 can be plugged into the open ends of the water supply pipe 3 and the semi-circular water pipe 21 respectively, or connected by fastener clamps.

[0041] In some embodiments, the left and right connectors of the cross joint 24 are threadedly connected to the corresponding open ends.

[0042] See Figure 4 Optionally, the open end of the semi-circular water pipe 21 may be fitted with a first pipe fitting 23, which has internal threads; the first pipe fitting 23 may be a rotary joint. See also Figure 5 The four ports of the cross joint 24 are all machined with external threads 28, and the left and right ends of the cross joint 24 are screwed into the first pipe joint 23. The two ends of the water supply pipe 3 can also be fitted with swivel joints with built-in threads.

[0043] Furthermore, the lower end of the cross-shaped connector 24 is used to connect to the water supply pipe 3, and the upper end is used to connect to the water supply pipe 3 or to be sealed with a plug. Specifically, the lower end of the cross-shaped connector 24 of the cleaning ring 2 starting from the second layer downwards is used to connect to the water supply pipe 3, and the upper end is also used to connect to the water supply pipe 3. The lower end of the cross-shaped connector 24 of the cleaning ring 2 of the first layer is used to connect to the water supply pipe 3, while the upper end is sealed with a plug.

[0044] Furthermore, the spray nozzles 22 are evenly distributed on the semi-circular water pipe 21; each spray nozzle 22 is provided with a nozzle 29. Optionally, the spray nozzle 22 can be a commercially available rotary spray nozzle, which can increase its coverage area.

[0045] Furthermore, the spray direction of the nozzle 29 is perpendicular to the outer wall of the tower 1. This ensures the impact force of the high-pressure water mist sprayed from the nozzle 29.

[0046] See Figure 2 The lower support ring 202 includes two stacked semi-circular support rings 26, and the ends of the two semi-circular support rings 26 are connected by a locking sleeve 27, thereby connecting the two semi-circular support rings 26 into a ring, which can be fitted onto the outer wall of the tower 1.

[0047] In one application scenario, during the initial cleaning, the symmetrical semi-circular structure of the cleaning ring 2 is connected to the left and right semi-circular water pipes 21 and semi-circular support rings 26 via cross connectors 24 and locking sleeves 27. This allows the cleaning ring 2 to be fitted onto the tower 1. After several cleaning rings 2 are installed, they are connected by water supply pipes 3 to form a vertically connected water supply pipeline. Once installed, the cleaning ring 2 can be permanently fitted onto the tower 1. Within the same cleaning ring 2, the diameter of the semi-circular water pipe 21 is larger than the diameter of the semi-circular support ring 26. The diameter of the semi-circular support ring 26 is the same as the diameter of the tower 1 at which it is fitted and fixed. Furthermore, the diameter of the cleaning ring 2 adjusts according to the diameter of the tower 1 when fitted at different heights on the tower.

[0048] During subsequent regular cleaning, the transport vehicle 8 transports the water tank 7 and water pump 6 to the vicinity of the bottom of the tower. Then, the water supply pipe 3 is connected to the water pump through the second pipe connector 4, which enables the entire flushing and cleaning system to operate. Depending on the cleanliness of the surface of the tower 1, the pressure of the high-pressure water mist sprayed from the nozzle 29 can be controlled by adjusting the throttle valve 5, thereby ensuring the cleaning effect. The entire operation is simple to operate, requires no climbing, and has a large cleaning coverage area and short cleaning time.

[0049] It should be noted that all the devices (parts whose specific structures are not specified) selected in this application are general standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
