Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower detection technology, specifically a wind turbine tower tilt monitoring device. Background Technology

[0002] With the ever-increasing global demand for clean energy, wind power has rapidly developed as an important form of renewable energy utilization. The stability of the wind turbine tower, as the supporting structure for the wind turbine generator, is crucial. During long-term operation, wind turbine towers are affected by a variety of complex factors. If a wind turbine tower tilts and is not detected and addressed in time, the consequences can be disastrous. Even a slight tilt may reduce power generation efficiency, affect the normal operation of the turbine, cause uneven stress on the blades, and accelerate equipment wear; severe tilting may lead to tower collapse, causing huge economic losses, not only damage to the turbine itself, but also losses in power generation during maintenance, replacement, and downtime, and may even endanger the safety of surrounding personnel and facilities.

[0003] During the use of wind turbine towers, monitoring the tower's tilt is particularly important. It is also necessary to make a rough judgment on the tower's tilt angle in order to determine whether the tilt angle is within a safe range. Therefore, a wind turbine tower tilt monitoring device is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wind turbine tower tilt monitoring device, which solves the problem of needing to monitor the tilt of the tower and make a rough judgment on the tilt angle during tower use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wind turbine tower tilt monitoring device, including an installation ground, a wind turbine tower body fixedly installed at the top of the installation ground, a monitoring component provided at the top of the installation ground, and an angle measuring component provided on the outer wall of the wind turbine tower body;

[0006] The monitoring component includes a fixed ring, and a set of connecting rods are fixedly installed on the outer wall of the fixed ring. Each set of connecting rods has a cylinder fixedly installed on its outer wall.

[0007] The angle measuring component includes an annular slide plate, with a rolling ball rolling on the inner wall of the annular slide plate, a rotating ring rotatably mounted at the bottom end of the annular slide plate, a movable plate fixedly mounted at the bottom end of the rotating ring, and a plumb line and a vertical plate fixedly mounted at the bottom end of the movable plate.

[0008] Preferably, a plumb block is fixedly installed at the bottom end of the plumb line, and the plumb line is fitted to one side of the vertical plate.

[0009] Preferably, the annular sliding plate is fixedly installed on the outer wall of the wind turbine tower body, and an annular baffle is fixedly installed at the top of the annular sliding plate to prevent the rolling ball from falling off the annular sliding plate. The vertical plate is parallel to the central axis of the wind turbine tower body.

[0010] Preferably, an annular placement plate is fixedly installed at the top of the installation ground, and a set of pressure sensors is fixedly installed at the bottom of the inner wall of the annular placement plate, with an arc-shaped support plate fixedly installed at the top of each set of pressure sensors.

[0011] Preferably, the fixing ring is fixedly installed on the outer wall of the wind turbine tower body, the bottom ends of a group of cylinders are respectively attached to the surface of a group of arc-shaped support plates, and the top of the installation ground is respectively fixedly installed with a control panel and an alarm light.

[0012] Preferably, the control panel is electrically connected to a group of pressure sensors and to an alarm light.

[0013] Beneficial effects

[0014] This utility model provides a wind turbine tower tilt monitoring device. Compared with the prior art, it has the following advantages:

[0015] 1. This wind turbine tower tilt monitoring device works as follows: When the wind turbine tower tilts, the annular sliding plate tilts along with it. A rolling ball rolls within the annular sliding plate, always maintaining its lowest position under gravity. Its position relative to the annular sliding plate reflects the tilt position of the wind turbine tower. Rotating the moving plate, which rotates via the rotating ring, positions the moving plate to the position of the rolling ball. At this point, the plumb line at the bottom remains vertically downward under gravity, and the vertical plate is parallel to the central axis of the wind turbine tower. Therefore, by observing the angle between the plumb line and the vertical plate, the tilt angle of the wind turbine tower can be directly determined, allowing staff to quickly make a preliminary judgment, decide on subsequent response strategies, and improve maintenance efficiency.

[0016] 2. This wind turbine tower tilt monitoring device has a fixed ring attached to the outer wall of the wind turbine tower body. A set of connecting rods and cylinders connected to the ring move together with the wind turbine tower body. A set of pressure sensors at the bottom of the inner wall of the annular placement plate on the ground supports the cylinders through an arc-shaped support plate. When the tower is vertical, the pressure of each cylinder on the arc-shaped support plate is evenly distributed, and the pressure values ​​measured by the pressure sensors are in a relatively stable and balanced state. Once the tower tilts, the pressure of the cylinders on the corresponding arc-shaped support plate on one side of the tilt increases, while the pressure on the other side decreases. The pressure sensors convert the pressure change into an electrical signal and transmit it to the control panel. The control panel then sends an electrical signal to the alarm light, causing the alarm light to sound, thereby notifying the staff that the wind turbine tower body has tilted.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-6 The first embodiment is shown: a wind turbine tower tilt monitoring device, including a mounting ground 1, a wind turbine tower body 2 fixedly mounted on the top of the mounting ground 1, a monitoring component 5 provided on the top of the mounting ground 1, and an angle measuring component 6 provided on the outer wall of the wind turbine tower body 2.

[0027] The monitoring component 5 includes a fixed ring 53, a set of connecting rods 54 are fixedly installed on the outer wall of the fixed ring 53, and a cylinder 55 is fixedly installed on the outer wall of each set of connecting rods 54;

[0028] The angle measuring component 6 includes an annular slide plate 61. A rolling ball 63 is rolled on the inner wall of the annular slide plate 61. Because the rolling ball 63 is rolled inside the annular slide plate 61, the friction is small. When the annular slide plate 61 is tilted, the rolling ball 63 will roll to the tilt direction. A rotating ring 64 is rotatably installed at the bottom end of the annular slide plate 61. A movable plate 65 is fixedly installed at the bottom end of the rotating ring 64. The movable plate 65 can easily drive the rotating ring 64 to rotate, thereby moving the plumb line 66 and the vertical plate 68 on the movable plate 65 to the rolling ball 63. The plumb line 66 and the vertical plate 68 are fixedly installed at the bottom end of the movable plate 65, respectively.

[0029] A plumb block 67 is fixedly installed at the bottom of the plumb line 66. The plumb line 66 is attached to one side of the vertical plate 68. At this time, the plumb line 66 will remain vertical and downward under the action of the gravity of the plumb block 67. The vertical plate 68 is at the same tilt angle as the central axis of the wind turbine tower body 2. Therefore, the angle between the plumb line 66 and the vertical plate 68 can be used to determine the tilt angle of the wind turbine tower body 2.

[0030] The annular sliding plate 61 is fixedly installed on the outer wall of the wind turbine tower body 2. An annular baffle 62 is fixedly installed at the top of the annular sliding plate 61 to prevent the rolling ball 63 from falling off the annular sliding plate 61. The vertical plate 68 is parallel to the central axis of the wind turbine tower body 2.

[0031] Figures 1-6 The second embodiment is shown, and its main difference from the first embodiment is:

[0032] An annular placement plate 51 is fixedly installed at the top of the installation ground 1. A set of pressure sensors is fixedly installed at the bottom of the inner wall of the annular placement plate 51. An arc-shaped support plate 52 is fixedly installed at the top of each set of pressure sensors.

[0033] The fixed ring 53 is fixedly installed on the outer wall of the wind turbine tower body 2. The bottom ends of a set of cylinders 55 are respectively attached to the surface of a set of arc-shaped support plates 52. The control panel 3 and the alarm light 4 are respectively fixedly installed on the top of the installation ground 1. When the wind turbine tower body 2 tilts, it will cause the fixed ring 53 and cylinders 55 to tilt, thereby causing the pressure of the pressure sensor under the arc-shaped support plate 52 to change.

[0034] Control panel 3 is electrically connected to a set of pressure sensors and to alarm light 4. After the pressure sensors sense a pressure change, they convert the pressure signal into an electrical signal and send it back to control panel 3. Then, control panel 3 can control alarm light 4 to sound an alarm, making it easier for staff to detect.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the wind turbine tower body 2 is first fixedly installed on the installation ground 1. The fixing ring 53 is fixed to the outer wall of the wind turbine tower body 2, and a set of connecting rods 54 and cylinders 55 connected to it move together with the wind turbine tower body 2. A set of pressure sensors at the bottom of the inner wall of the annular placement plate 51 on the installation ground 1 supports the cylinders 55 through the arc-shaped support plate 52. When the tower is vertical, the pressure of each cylinder 55 on the arc-shaped support plate 52 is evenly distributed, and the pressure value measured by the pressure sensors is in a relatively stable and balanced state. Once the tower tilts, the pressure of the cylinder 55 on the corresponding arc-shaped support plate 52 increases on the tilting side, while the pressure on the other side decreases. The pressure sensor converts the pressure change into an electrical signal and transmits it to the control panel 3. The control panel 3 then sends an electrical signal to the alarm light 4, causing the alarm light 4 to sound an alarm, thus notifying the staff that the wind turbine tower body 2 has tilted. At the same time, when the wind turbine tower body 2 tilts, the annular sliding plate 61 will tilt along with the wind turbine tower body 2. At this time, the rolling ball 63 rolls inside the annular sliding plate 61, always maintaining the lowest position under the action of gravity. The position of the vertical plate 65 relative to the annular sliding plate 61 reflects the tilt position of the wind turbine tower body 2. At this time, the moving plate 65 is rotated through the rotating ring 64, and the moving plate 65 is rotated to the position of the rolling ball 63. At this time, the plumb block 67 at the bottom of the plumb line 66 remains vertically downward under the action of gravity, and the vertical plate 68 is parallel to the central axis of the wind turbine tower body 2. Therefore, by observing the angle between the plumb line 66 and the vertical plate 68, the tilt angle of the wind turbine tower body 2 can be intuitively judged, which makes it easier for staff to make a preliminary judgment, decide on subsequent response strategies, and improve operation and maintenance efficiency.
