Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a dual-axis tilt sensor for wind turbines. Background Technology

[0002] Wind turbine towers, subjected to long-term combined effects of wind loads, rotor torque, their own weight, and meteorological and geological factors, may tilt. Dual-axis tilt sensors can monitor the tower's tilt angle in two vertical directions in real time. If the tilt exceeds the safe range, an early warning can be issued, allowing personnel to take appropriate measures, such as inspecting the tower foundation and reinforcing the tower. This prevents serious safety accidents such as tower collapse caused by excessive tilting, ensuring the overall structural safety of the wind turbine.

[0003] Wind turbine towers are made of steel plates, making it impossible to drill holes in the surface. Therefore, dual-axis tilt sensors are mainly attached with adhesive. During fixing, a force needs to be applied to ensure that the dual-axis tilt sensor is firmly in contact with the adhesive until the adhesive dries. Only then can the pressure on the dual-axis tilt sensor be released. However, the existing fixing method involves manually applying force to fix it, which is difficult to operate and the force is prone to change. As a result, the fixing effect between the dual-axis tilt sensor and the wind turbine tower is relatively poor, so there is an urgent need to improve it. Utility Model Content

Detailed Implementation

[0035] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] refer to Figure 1 A dual-axis tilt sensor for a wind turbine includes a dual-axis tilt sensor body 1, an adhesive mechanism 2, a mounting box 3, and a force application mechanism 4. The dual-axis tilt sensor body 1 has an ear plate 1.1 on its side. The adhesive mechanism 2 has the mounting box 3 on one side and can be bonded to the surface of the wind turbine tower on the other side. The mounting box 3 has a connecting plate 3.1, which is used to press the ear plate 1.1 onto the adhesive mechanism 2. The force application mechanism 4 is mounted on the mounting box 3 and is used to apply pressure to the adhesive mechanism 2 towards the surface of the wind turbine tower.

[0037] Through the cooperation of the adhesive mechanism, the mounting box, and the force application mechanism, the mounting box installs the dual-axis tilt sensor body onto the adhesive mechanism, and then the adhesive mechanism fixes the dual-axis tilt sensor body onto the wind turbine tower. The installation is convenient and reliable, and it is easy to detect whether the wind turbine tower is tilted. The force application mechanism further improves the reliability of the adhesive.

[0038] refer to Figure 2 and Figure 3 The adhesive mechanism 2 includes an adhesive plate 2.1 and a connecting block 2.2. One side of the adhesive plate 2.1 is connected to the mounting box 3, and the other side can be connected to the surface of the wind turbine tower. The mounting box 3 has a sliding cavity, and the connecting block 2.2 is slidably disposed in the sliding cavity for contacting or moving away from the adhesive plate 2.1. The force-applying mechanism 4 abuts against the connecting block 2.2 to press the connecting block 2.2 firmly onto the adhesive plate 2.1. The connecting block 2.2 is provided with a slider 2.3, and the side wall of the sliding cavity is provided with a groove that matches the slider 2.3. The slider 2.3 is slidably disposed in the groove. The adhesive mechanism 2 further includes a slide rod 2.4 and a compression spring 2.5; the slide rod 2.4 is arranged in the sliding cavity along the direction perpendicular to the adhesive plate 2.1, and the slider 2.3 is provided with a sliding hole that matches the slide rod 2.4, and the sliding hole is sleeved on the slide rod 2.4; the compression spring 2.5 is sleeved on the slide rod 2.4 and is placed on the side of the slider 2.3 away from the adhesive plate 2.1.

[0039] By adopting the above configuration, when the slider slides in the groove, it simultaneously slides on the surface of the slide rod. The rebound force of the compression spring will firmly press the slider against the adhesive plate, thereby improving the contact effect between the adhesive plate and the tower cylinder in the later stage. The compression spring 2.5 is in a compressed state and is used to apply force to the slider 2.3 in the direction of the adhesive plate 2.1. This can avoid the problem of the adhesive plate rebounding.

[0040] The force-applying mechanism 4 includes a U-shaped plate 4.1 and an electric push rod 4.3; the two ends of the U-shaped plate 4.1 are respectively fixedly mounted on the mounting box 3, and the electric push rod 4.3 is provided in the middle of the U-shaped plate 4.1; the mounting box 3 is provided with a through hole 4.4 that matches the electric push rod 4.3, so that the electric push rod 4.3 can extend into the sliding cavity and abut against the connecting block 2.2.

[0041] With the above settings, the output end of the electric push rod can be inserted normally into the interior of the mounting box through the through hole, so as to apply force to the connecting block, thereby making full contact between the adhesive plate and the adhesive on the surface of the tower through the electric push rod.

[0042] The U-shaped plate 4.1 is fixedly connected to the mounting box 3 by screw 4.2.

[0043] A pressure sensor 4.5 is installed on the connecting block 2.2 at the position corresponding to the electric push rod 4.3. The pressure sensor in this embodiment is a publicly available technology, specifically the Vishay TE series. The dual-axis tilt sensor selected is model SCA126T.

[0044] The pressure sensor allows the electric actuator to transmit a signal to the control center after a specified force is applied. The control center can then control the electric actuator to stop applying greater pressure to the connecting block, ensuring that the adhesive board and glue can make uniform contact.

[0045] refer to Figure 4 The adhesive plate 2.1 has an adhesive layer 2.6 on the side near the tower surface of the wind turbine. The adhesive layer provides an initial adhesive force during installation and fixation of the device.

[0046] The connecting plate 3.1 and the ear plate 1.1 are fixedly connected by screw 6. The hole on the connecting plate for installing screw 6 is a countersunk hole, which makes it easy to hide the head of screw 6, avoid bumps, and improve the appearance.

[0047] The working principle and usage procedure of the dual-axis tilt sensor for wind turbines in this embodiment are as follows:

[0048] In use, fix the ear plate on the side of the dual-axis tilt sensor body to the connecting plate using screw one. Then, peel off the film on the side of the adhesive layer. At the same time, apply strong adhesive to both ends of the adhesive plate and attach the adhesive layer to the upper side of the wind turbine tower, ensuring the adhesive at both ends of the adhesive plate is in contact with the tower surface. Then, fix the U-shaped plate to the side of the mounting box using screw two. Open the electric push rod; after the electric push rod extends, it inserts into the through hole and applies pressure to the connecting block. The force applied by the electric push rod will directly contact the pressure sensor. When the force applied by the electric push rod reaches... When the pressure sensor reaches the set threshold, the control center receives a signal and controls the electric push rod to stop applying pressure, allowing the adhesive plate to contact the glue and maintaining a stable pressure until the glue dries. At this point, the dual-axis tilt sensor body is firmly fixed to the upper side of the tower. The dual-axis tilt sensor body monitors the wind turbine tower. When the wind turbine tower tilts, the dual-axis tilt sensor body transmits a signal to the control center, which then activates the alarm mechanism to sound an alarm, thus serving as a warning.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model within the spirit and principles of the present utility model.
