[0015] (III) Beneficial effects

[0016] The beneficial effects of the utility model are as follows: in the actual implementation process, when it is necessary to add lubricating oil, the sealing cover is opened at this time, and then the lubricating oil is poured in from the pull ring, and then the lubricating oil enters the filter screen, and the lubricating oil entering the filter screen is gradually filtered, and the filtered lubricating oil leaks out from the opening of the frame body, and when the filter screen needs to be cleaned, the pull ring is pulled at this time, and the pull ring drives the filter screen to move, and then the filter screen can be taken out, and when the filter screen is cleaned, the filter screen is placed in the frame, and when the pull ring is overlapped in the fixed ring, the filtration of the lubricating oil and the cleaning of the filter screen are completed. When the temperature is low, resulting in increased viscosity and decreased fluidity of the lubricating oil, the operator can send instructions to the receiver through the controller, and the receiver receives the instructions After that, the heating wire is activated and starts to generate heat. The heat is transferred through the heat transfer plate and gradually diffuses outward, so that the lubricating oil covers the surface of the heat transfer plate and absorbs heat. As the temperature of the lubricating oil increases, its viscosity decreases, its fluidity is improved, and its flow rate increases accordingly. In this way, even in a cold environment, the lubricating oil can be effectively heated, ensuring the fluidity of the lubricating oil and avoiding the problem of slow lubricating oil injection speed caused by weather reasons, thereby ensuring the normal operation and maintenance of mechanical equipment. This avoids the need to load the lubricating oil into the system before the lubrication operation of the wind turbine. However, in this process, the lubricating oil sometimes solidifies into a solid due to the temperature difference, which may cause the lubrication system to be blocked, causing the filling process to be delayed.

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 4 As shown, the utility model is an automatic oil drip lubrication for a wind turbine, comprising a storage box 1, a controller 2 is provided on the storage box 1, a pressure gauge 3 is provided in the storage box 1, a feed port 4 is opened on the storage box 1, a filter device 5 is provided in the feed port 4, a heating device 6 is provided in the filter device 5, and the filter device 5 comprises a sealing cover 51;

[0025] The sealing cover 51 is externally connected with a connecting rope 52 , one end of the connecting rope 52 is connected with a fixing ring 53 , a frame 54 is connected below the fixing ring 53 , a pull ring 55 is installed inside the fixing ring 53 , a filter screen 56 is connected below the pull ring 55 , and a sealing gasket 57 is clamped inside the sealing cover 51 . In the actual implementation process, when it is necessary to add lubricating oil, the sealing cover 51 is opened, and then the lubricating oil is poured in from the pull ring 55, and then the lubricating oil enters the filter 56, and the lubricating oil entering the filter 56 is gradually filtered, and the filtered lubricating oil leaks out from the opening of the frame 54, and when it is necessary to clean the filter 56, the pull ring 55 is pulled, and the pull ring 55 drives the filter 56 to move, and then the filter 56 can be taken out, and when the filter 56 is cleaned, the filter 56 is placed in the frame 54, and when the pull ring 55 is overlapped in the fixing ring 53, the filtering of the lubricating oil and the cleaning of the filter 56 are completed, thereby avoiding the need to load the lubricating oil into the system before the lubrication operation of the wind turbine generator set, however, in this process, the lubricating oil sometimes solidifies into a solid due to the temperature difference, which may cause the lubrication system to be blocked, causing the filling process to be delayed.

[0026] Optionally, the sealing cover 51 is clamped outside the fixing ring 53, and the sealing gasket 57 is overlapped outside the fixing ring 53. In the actual implementation process, by providing the sealing cover 51 and the sealing gasket 57, the sealing cover 51 forms an effective sealing layer at the position of the fixing ring 53 through close cooperation with the sealing gasket 57, thereby preventing external impurities, dust or liquid from penetrating into the interior of the device. This sealing measure ensures the cleanliness of the interior of the device and the safety of the components, and maintains the normal operation and long-term reliability of the machine.

[0027] Optionally, the fixing ring 53 is connected to the feed port 4, and the filter screen 56 is overlapped in the frame 54. In the actual implementation process, by setting the fixing ring 53 and the feed port 4, the precise matching of the fixing ring 53 and the feed port 4 ensures the stable positioning of the feed port 4. Through this structural design, the fixing ring 53 can maintain a constant position during the feeding process to prevent any unnecessary shaking or displacement.

[0028] Optionally, the heating device 6 includes a base 61, which is connected to the filter 56, and a receiver 62 is provided in the base 61. In the actual implementation process, when the temperature is low and the viscosity of the lubricating oil increases and the fluidity decreases, the operator can send a command to the receiver 62 through the controller 2. After receiving the command, the receiver 62 activates the heating wire 63, and the heating wire 63 starts to generate heat. The heat is transferred through the heat conducting plate 64 and gradually diffuses outward, so that the lubricating oil covers the surface of the heat conducting plate 64 and absorbs heat. As the temperature of the lubricating oil increases, its viscosity decreases, the fluidity is improved, and the flow rate increases accordingly. In this way, even in a cold environment, the lubricating oil can be effectively heated, ensuring the fluidity of the lubricating oil and avoiding the problem of slow lubricating oil injection speed caused by weather reasons, thereby ensuring the normal operation and maintenance of the mechanical equipment.

[0029] Optionally, a heating wire 63 is connected to the receiver 62, and a heat conducting plate 64 is connected to the base 61. In actual implementation, by providing the receiver 62 and the heating wire 63, the combined use of the receiver 62 and the heating wire 63 allows the receiver 62 to activate the heating wire 63 after receiving a specific instruction. Such a design greatly improves the convenience of remote control, and the user or the control system can remotely start or shut down the heating process without directly contacting the heating wire 63.

[0030] Optionally, the heating wire 63 is overlapped in the heat conducting plate 64, and the heat conducting plate 64 is overlapped in the filter screen 56. In the actual implementation process, by setting the heating wire 63 and the heat conducting plate 64, the cooperation between the heating wire 63 and the heat conducting plate 64 ensures that when the heating wire 63 is activated, the heat generated can be concentrated inside the heat conducting plate 64. This design enables the heat to be effectively retained and conducted inside the heat conducting plate 64, avoiding excessive heat loss. Subsequently, through the thermal conductivity of the heat conducting plate 64, the heat can be evenly transferred to the outside of the heat conducting plate 64, so that the external lubricating oil can be evenly affected by the heat.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model, and the standard parts used in the utility model can be purchased from the market, special-shaped parts can be customized according to the description and the drawings, and the specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art.
