Description

Technical Field

[0001] This utility model belongs to the field of daily operation and maintenance technology of wind turbine units, and specifically relates to a wind turbine radiator cleaning device. Background Technology

[0002] As a key piece of equipment in the renewable energy field, the operational stability of wind turbines directly affects power generation efficiency and maintenance costs. Among them, the radiator is a key component that ensures the normal operation of the core components of the wind turbine (such as generators and gearboxes). Its function is to dissipate the heat generated inside the unit to the external environment through heat exchange. However, wind turbines usually operate in harsh environments such as dusty, sandstorm, or salt spray environments. The radiator filter is easily clogged by contaminants such as dust, oil, or salt, resulting in a significant decrease in heat dissipation efficiency and even serious failures such as overheating and shutdown of the unit. Therefore, regular and efficient cleaning of the radiator filter is an important maintenance measure to ensure the reliable operation of wind turbines. Currently, a cleaning hood is used in conjunction with a high-pressure water gun to clean the radiator of wind turbines. For example, the wind turbine heat dissipation component cleaning device disclosed in the existing patent with publication number CN214247586U can clean the radiator filter of the wind turbine by rinsing.

[0003] However, existing cleaning devices still have the following technical shortcomings:

[0004] 1. Limited rinsing coverage: The water guns in the existing cleaning hoods are usually designed as single pipes and single heads, which can only rinse a local area of ​​the filter screen. After cleaning one area, the installation position of the water gun must be manually adjusted or the cleaning hood must be moved to cover other areas. This "cleaning in sections" mode makes the cleaning process cumbersome and time-consuming, which is difficult to meet the needs of rapid maintenance of large-scale wind turbine units.

[0005] 2. Insufficient installation stability: The existing cleaning covers are mostly connected to the radiator shell by simple buckles or hooks. During high-pressure water rinsing, they are prone to shaking or falling off due to the impact of the water flow, which can lead to cleaning interruption or even equipment damage. In addition, loose cleaning covers can also cause rinsing water to splash out, polluting the surrounding environment of the unit.

[0006] 3. Low cleaning efficiency: Due to the limited rinsing area and poor installation stability, the existing equipment needs to be frequently repositioned or repeatedly fixed. The cleaning time for a single unit usually exceeds 2 hours, which seriously restricts the operation and maintenance efficiency of wind turbine units.

[0007] Therefore, this utility model proposes a cleaning device for wind turbine radiators. Utility Model Content

[0008] The purpose of this invention is to provide a wind turbine radiator cleaning device to solve the problems mentioned in the background art.

[0011] And multiple locking structures located on the outside of the cleaning hood.

[0012] Preferably, the bottom surface of the cleaning hood is provided with a drain pipe, and the drain pipe is connected to the inside of the cleaning hood.

[0013] Preferably, the locking structure includes a threaded base rod fixed to the outer surface of the cleaning hood, a pressing block and a locking threaded ring sleeved on the surface of the threaded base rod, a pressure column fixed to the inner side of the top of the pressing block, a locking pressure plate fixed to the side of the pressure column, and an anti-slip pad installed on the side of the locking pressure plate and abutting against the outer shell of the wind turbine radiator.

[0014] Preferably, the locking threaded ring is threadedly connected to the threaded base rod, and the circumferential surface of the locking threaded ring is provided with multiple integral strip-shaped protrusions.

[0015] Preferably, a circular hole is provided through the bottom surface of the pressing block, and the circular hole corresponds to the threaded base rod.

[0016] Preferably, the anti-slip pad has multiple strip-shaped anti-slip grooves on its side.

[0018] Preferably, the inlet pipe of the high-pressure water pump is connected to an inlet hose, and the inlet hose extends into the water tank.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By designing an inner base tube and configuring multiple inclined nozzles inside the cleaning hood, this application achieves simultaneous rinsing of multiple areas of the radiator filter screen. Combined with the locking structure at the edge of the cleaning hood to enhance installation stability, it significantly improves cleaning efficiency, reducing the cleaning time of a single unit by more than 75% compared with the prior art. Moreover, the locking structure effectively prevents the rinsing water from splashing out and the device from falling off, protecting the surrounding environment of the unit and avoiding secondary damage, thus providing an efficient and safe solution for the operation and maintenance of wind turbine units.

[0037] In this embodiment, preferably, the inlet pipe of the high-pressure water pump 5 is connected to an inlet hose, and the inlet hose extends into the water tank 6, so that after the high-pressure water pump 5 is started, it can smoothly draw water out of the water tank 6 and send it into the U-shaped base pipe 9.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
