Description

Technical Field

[0001] The utility model relates to the technical field of wind power towers, and in particular to an installation device for a GNSS displacement monitoring device for a wind power tower. Background Art

[0002] Wind power generation is a current direction of new energy development, and the towers of wind power generation devices that have been built every year will collapse or break during use. In order to monitor the displacement of the tower and other data, the commonly used method is to use a GNSS displacement monitoring device (Global Navigation Satellite System) for displacement monitoring. The GNSS displacement monitoring device consists of two parts: a receiver and an antenna. It is currently widely used in static displacement measurements such as landslide deformation monitoring, tailings pond deformation monitoring, reservoir dam deformation monitoring, and old and dangerous building deformation monitoring. By continuously receiving the original data from the positioning satellite, an accurate geodetic coordinate is calculated through post-processing software. When the GNSS antenna fixed on the surface of the structure is displaced, the actual deformation of the horizontal and vertical displacements of the fixed position of the GNSS antenna can be accurately calculated by comparing the geodetic coordinates calculated by the post-processing software.

[0003] In actual use, GNSS displacement monitoring devices usually require an external power supply, and the battery needs to be replaced frequently during use, or power supply lines need to be set up, which is very time-consuming and labor-intensive.

[0004] To this end, an installation device for a wind turbine tower GNSS displacement monitoring device is proposed to solve the above technical problems. Utility Model Content

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0018] It also includes a photosensitive sensor arranged on the mounting plate 6 , the photosensitive sensor is electrically connected to the controller of the solar panel 7 , and the controller is electrically connected to the drive motor 3 .

[0019] In the present utility model, the main working principle is as follows: the present utility model device mainly uses solar power generation to power the storage battery 8, and then supplies the GNSS displacement monitoring device for normal operation. Specifically, by setting an inclined solar panel 7 on the mounting plate 6, it is used to absorb sunlight. By setting a photosensitive sensor, sensing the light intensity and light angle, inputting a weak electrical signal to the controller, the controller outputs a control signal to start the drive motor 3, the output shaft of the drive motor 3 drives the driving gear 4 to rotate, and then drives the driven gear 5 to rotate, and the tower 10 in the tower sleeve 1 is driven by the driven gear 5 to rotate in the rotating bearing, thereby realizing the rotation of the tower 10 and the mounting plate 6 on the tower 10, realizing angle adjustment, ensuring that the solar panel 7 can face the sun at any time, and improving the efficiency of solar power generation. The GNSS displacement monitoring device is installed at the bottom of the tower sleeve 1 so that it will not be affected by the rotation. The controller here can be implemented by a programmable PLC controller. As a very mature existing technology, its internal circuit structure is not described here.

[0020] As a preferred embodiment, the lower surface of the base 11 is provided with embedded steel bars, and the embedded steel bars are embedded in the concrete layer of the ground.

[0021] In this embodiment, the tower sleeve 1 is fixed in the concrete layer of the ground by embedded reinforcements under the base 11, thereby providing sufficient support force for the upper structure and preventing the tower sleeve 1 and the tower 10 from tilting.

[0022] As a preferred embodiment, an L-shaped mounting frame 9 is provided on the edge of the upper surface of the mounting plate 6 , the solar panel 7 is obliquely arranged at the end of the mounting frame 9 , and the bottom of the solar panel 7 exceeds the projection range of the mounting plate 6 .

[0023] In this embodiment, the solar panel 7 is obliquely arranged on the edge of the mounting plate 6 through the mounting frame 9, and the bottom of the solar panel 7 is extended out of the projection range of the mounting plate 6 to effectively reduce the area occupied on the mounting plate 6, thereby avoiding affecting the judgment of the light sensor on sunlight exposure at various angles.

[0024] As a preferred embodiment, the protection box 2 is also provided with an openable and closable inspection door.

[0025] In this embodiment, an openable and closable inspection door is provided on the protection box 2, thereby facilitating the inspection and maintenance of the driving gear and the driving motor in the protection box.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
