Description

Technical Field

[0001] This utility model relates to the field of wind turbine pitch drive technology, specifically a wind turbine pitch drive status display device. Background Technology

[0002] The status display screen on a wind turbine pitch drive is an indispensable component of a wind power generation system, playing a crucial role in real-time monitoring, fault alarms, data storage, and data backup. It helps maintenance personnel understand the operating status of the pitch system in a timely manner, identify potential problems early, and thus improve the overall performance and reliability of the wind turbine. The display screen design typically includes display modules, input / output modules, communication interfaces, control modules, and alarm modules. Through the collaboration of these modules, comprehensive monitoring of the pitch drive is achieved. During installation, a suitable installation location should first be selected, usually outside the pitch drive housing, ensuring the display screen's visibility and avoiding the influence of harsh environments. Next, a suitable mounting bracket should be fabricated or selected, ensuring that the bracket can securely hold the display screen and prevent vibration or displacement. Then, openings should be made in the housing, and the area around the openings should be treated with a waterproof sealant to prevent moisture and dust intrusion. Next, complete the electrical connection between the display screen and the control system to ensure stable and error-free data transmission; for example, a wind turbine pitch drive status display device disclosed in authorization announcement number CN220379284U includes a base and a display device body. A mounting assembly is provided above the base. The mounting assembly includes a mounting groove formed at the top of the base, and a mounting block is slidably connected inside the mounting groove. The bottom of the display device body is fixedly mounted to the top of the mounting block. Two movable grooves are formed inside the mounting groove, and threaded sleeves are rotatably connected to opposite side walls of the inner cavities of the two movable grooves. The mounting assembly allows for quick and easy movement of the display device body. The above technical solution allows for quick installation and disassembly, facilitating maintenance and replacement of the display device. However, during use, the display device is mounted on the housing of the wind turbine pitch drive via mounting components and a base. At this time, the display surface of the display device is perpendicular to the extended plane of the wind turbine pitch drive housing. Therefore, the visibility of the installed display device is poor, and it is difficult for operators to clearly see the screen content. Operators need to observe the display screen at an unnatural angle, which not only increases the difficulty of the work but may also lead to inaccurate information reading, especially in emergency situations where it is impossible to quickly obtain the status information of the pitch drive. Utility Model Content

[0003] The purpose of this utility model is to provide a wind turbine pitch drive status display device. The back of the LED display screen is pre-attached to the assembly cavity starting from the surface of the pitch drive housing, so that the display plane of the LED display screen is parallel to the extension plane of the pitch drive housing. After the LED display screen is installed into the assembly cavity, the T-shaped elastic pin on the outer wall of the LED display screen connects automatically with the internal threaded guide post to prevent the LED display screen from falling out of the assembly cavity, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine pitch drive status display device, comprising a pitch drive housing and an LED display screen for parallel installation with the pitch drive housing. The pitch drive housing has an assembly cavity for inserting the LED display screen. At least two mutually symmetrical T-shaped elastic pins are provided on one outer wall of the LED display screen. An internally threaded guide post concentric with the T-shaped elastic pins and for insertion of the T-shaped elastic pins is installed on one inner wall of the pitch drive housing. A rectangular notch is provided on the upper surface of the pitch drive housing for downward movement of the T-shaped elastic pins. An outwardly expanding edge is provided on the outer wall of the LED display screen, and the lower surface of the outwardly expanding edge is in contact with the upper surface of the pitch drive housing.

[0005] Preferably, an L-shaped support plate is integrally formed on one side of the top of the pitch driver housing, and the bottom of the L-shaped support plate is in contact with the bottom of the LED display screen.

[0006] Preferably, the T-shaped elastic pin includes an outer guide sleeve fixed to one side of the outer wall of the LED display screen and a stop head elastically installed on one side of the outer wall of the outer guide sleeve. The stop head has a rounded corner on the side of the outer wall away from the outer guide sleeve, and the stop head is used to insert into the internal threaded guide post.

[0007] Preferably, a pin is slidably installed inside the outer guide sleeve, one end of which is fixedly connected to the outer wall of the other side of the stop. A return spring concentric with the pin is fixed on the outer wall of the outer guide sleeve near the stop, one end of which is fixedly connected to the outer wall of the other side of the stop.

[0008] Preferably, a threaded shaft is installed inside the internal threaded guide post, one end of which extends through to the outside of the pitch drive housing. The threaded shaft is used to rotate the lateral movement and push the stop head out of the internal threaded guide post.

[0009] Preferably, the internal threaded guide post and the stop are both made of stainless steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The wind turbine pitch drive status display device pre-connects the back of the LED display screen to the mounting cavity on the surface of the wind turbine pitch drive housing, so that the display surface of the LED display screen is parallel to the extended plane of the wind turbine pitch drive housing. The design scheme of T-shaped elastic pin and internal threaded guide post self-connection makes the display screen naturally face the operation and maintenance personnel, and the displayed content is easier to observe. Due to the optimization of the installation angle, the operation and maintenance personnel can view the display screen from the front or near the front, avoiding unnatural viewing angles and enhancing the readability and visibility of information.

[0011] Furthermore, the use of T-shaped elastic pins and internal threaded guide posts makes the installation process of the display screen simpler and faster. Under this installation method, the LED display screen can be fixed by the automatic connection between the elastic pins and the internal threaded guide posts, avoiding complicated manual operations or additional fixing tools. When the maintenance personnel install the equipment, they only need to put the display screen into the preset assembly cavity to automatically complete the fixing process, which greatly reduces the installation difficulty.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 The present invention provides an embodiment of a wind turbine pitch drive status display device, comprising a pitch drive housing 1 and an LED display screen 2 for parallel installation with the pitch drive housing 1. The pitch drive housing 1 has an assembly cavity for the LED display screen 2 to be installed inside. At least two mutually symmetrical T-shaped elastic pins 3 are provided on one outer wall of the LED display screen 2. An internally threaded guide post 5 concentric with the T-shaped elastic pins 3 and for the T-shaped elastic pins 3 to be inserted is installed on one inner wall of the pitch drive housing 1. A rectangular notch 101 for the T-shaped elastic pins 3 to move downward is provided on the upper surface of the pitch drive housing 1. An outwardly expanding edge 201 is provided on the outer wall of the LED display screen 2, and the lower surface of the outwardly expanding edge 201 is in contact with the upper surface of the pitch drive housing 1.

[0020] An outwardly extended edge 201 is provided on the back of the LED display screen 2 for fixing and engaging with the assembly cavity of the pitch drive housing 1. The LED display screen 2 can both protect the LED display screen 2 and help ensure its stable positioning in the assembly cavity.

[0021] An L-shaped support plate 4 is integrally formed on one side of the top of the pitch driver housing 1, and the bottom of the L-shaped support plate 4 is in contact with the bottom of the LED display screen 2. When the LED display screen 2 is installed into the pitch driver housing 1, the L-shaped support plate 4 supports the LED display screen 2 so that the LED display screen 2 can be placed stably.

[0022] The T-shaped elastic pin 3 includes an outer guide sleeve 301 fixed on one side of the outer wall of the LED display screen 2 and a stop 303 elastically installed on one side of the outer wall of the outer guide sleeve 301. The stop 303 has a rounded corner on the outer wall away from the outer guide sleeve 301. The stop 303 is used to insert into the internal threaded guide post 5. A pin 302 is slidably installed inside the outer guide sleeve 301. One end of the pin 302 is fixedly connected to the other side of the outer wall of the stop 303. A return spring 304 concentric with the pin 302 is fixed on the outer wall of the outer guide sleeve 301 near the stop 303. One end of the return spring 304 is fixedly connected to the other side of the outer wall of the stop 303.

[0023] When the T-shaped elastic pin 3 and the internal threaded guide post 5 are connected, because the outer edge of the stop 303 is rounded, when the stop 303 and the internal threaded guide post 5 meet, the stop 303 can enter the interior of the internal threaded guide post 5 by itself under the action of the return spring 304. At this time, the pin 302 slides out part of the outer guide sleeve 301 until the stop 303 and the internal threaded guide post 5 are connected, so that the LED display screen 2 is not prone to loosening or displacement during long-term operation.

[0024] Both the internal threaded guide post 5 and the stop 303 are made of stainless steel. The internal threaded guide post 5 has a threaded shaft 6 installed inside. One end of the threaded shaft 6 extends to the outside of the pitch drive housing 1. The threaded shaft 6 is used to rotate and push the stop 303 out of the internal threaded guide post 5. The operator can manually rotate the threaded shaft 6 to push the stop 303 out of the internal threaded guide post 5, forcing the return spring 304 into a compressed state. Then the internal threaded guide post 5 and the T-shaped elastic pin 3 are disconnected, and the operator can remove the LED display 2 from the assembly cavity of the pitch drive housing 1.

[0025] In this embodiment, maintenance personnel first need to inspect the pitch drive housing 1 to ensure that the position, size, and shape of the mounting cavity on its upper surface meet the predetermined design standards. After ensuring that all components meet the specifications, the maintenance personnel pre-align the back of the LED display 2 with the inner wall of the mounting cavity. At this time, the display plane of the LED display 2 is parallel to the extension plane of the pitch drive housing 1, so that the displayed content is facing the maintenance personnel and achieves the best viewing angle. That is, the viewing angle of the LED display 2 is more in line with the standing or working angle of the staff, reducing the need for manual angle adjustment. When the LED display 2 is placed into the mounting cavity, the T-shaped elastic pin 3 and the internal threaded guide post 5 are automatically connected to form a tight fit, completing the self-positioning and automatic fixing process. The entire connection process does not require much manual intervention or complicated tools. Just align the LED display 2 and push it gently. After installation, the staff checks the position, angle, and fixing of the LED display 2. If a slight deviation or looseness is found in the installation position of the display, the maintenance personnel can quickly correct the problem by adjusting the connection state of the T-shaped elastic pin 3 and the internal threaded guide post 5.
