According to the auxiliary device for monitoring the perpendicularity of the wind power generation tower drum, the traction rope can be kept in a vertical state all the time through balance weight of the balance weight block, then the trigger block is kept in the middle of the interior of the pressure sensor, and when the perpendicularity of the tower drum changes, the installation mechanism inclines along with the tower drum, so that the perpendicularity of the tower drum is monitored. However, the counterweight block can drive the traction rope to keep a vertical state with the ground, so that the trigger block is in contact with the pressure trigger head, and then an alarm is triggered, and meanwhile, by utilizing a gravity counterweight mode, the auxiliary device has no excessive requirements on the mounting position and only needs to be mounted on the top surface, parallel to the ground, in the tower drum. And the installation convenience is improved while the timely early warning function is realized.

Description

Technical Field

[0001] This utility model relates to the technical field of verticality monitoring auxiliary equipment, specifically to a verticality monitoring auxiliary equipment for wind power generation towers. Background Technology

[0002] Wind turbine towers are generally cylindrical structures, assembled from several sections connected by bolts or welding. The top is connected to the nacelle, providing support and protection for components such as the nacelle, generator, and blades of the wind turbine generator set. Wind turbine tower verticality monitoring auxiliary equipment is a tool or device used to detect and ensure that the wind turbine tower (the tower-like structure that supports the wind turbine generator set) remains vertical during operation.

[0003] In existing technologies, total stations are typically used to measure the verticality of wind turbine towers. These stations measure the tower from a distance, using optical or laser technology to measure the three-dimensional coordinates of multiple points on the tower and calculate the verticality deviation. However, in practice, total stations cannot monitor tower verticality in real time and are only suitable for periodic professional inspections. They cannot provide timely warnings when the wind turbine tower tilts. Therefore, it is necessary to develop an auxiliary device for monitoring the verticality of wind turbine towers to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for monitoring the verticality of wind power towers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for monitoring the verticality of a wind power tower, comprising a connecting ring, wherein an installation mechanism is provided at the top of the connecting ring, and monitoring mechanisms are provided at the bottom and outside of the connecting ring.

[0006] Preferably, the installation mechanism includes a connecting bracket, which is fixedly installed on the top of the connecting ring. A first support plate and a second support plate are fixedly installed on the inner side of the connecting bracket. Bolts are provided inside the connecting bracket and the second support plate to facilitate the installation of the verticality monitoring auxiliary device through the installation mechanism.

[0007] Preferably, holes are provided at the corresponding positions of the connecting bracket and the second support plate and the bolt, and the bolt is slidably installed inside the holes provided inside the connecting bracket and the second support plate, so that the bolt can pass through the connecting bracket and the second support plate for installation.

[0008] Preferably, four connecting brackets are provided, and the four connecting brackets are evenly distributed on the top of the connecting ring, which improves the stability of the support.

[0009] Preferably, the monitoring mechanism includes an active buzzer body, which is fixedly installed on the left side of the connecting ring. A signal receiving and transmitting controller is fixedly installed on the right side of the connecting ring. A support rod is fixedly installed at the bottom of the connecting ring. A pressure sensor is fixedly installed on the inner side of the support rod. A traction rope is fixedly installed on the top inner side of the first support plate. A counterweight is fixedly installed at the end of the traction rope away from the first support plate. A trigger block is fixedly installed on the outside of the traction rope. A pressure trigger head is provided inside the pressure sensor, which facilitates the monitoring of the verticality of the wind power generation tower through the monitoring mechanism.

[0010] Preferably, the trigger block is located on the side of the traction rope away from the counterweight, and the trigger block is located inside the pressure sensor, so that the trigger block can normally trigger the pressure trigger head.

[0011] Preferably, four support rods are provided, and the four support rods are evenly distributed at the bottom of the connecting ring, which improves the stability of fixing the pressure sensor.

[0012] Compared with the prior art, this utility model provides an auxiliary device for monitoring the verticality of wind power towers, which has the following beneficial effects:

[0013] 1. This wind turbine tower verticality monitoring auxiliary device, through its monitoring mechanism, ensures that the traction rope remains vertical during use due to the counterweight, thereby keeping the trigger block centered inside the pressure sensor. When the tower's verticality changes, the installation mechanism tilts along with the tower, but the counterweight keeps the traction rope vertical to the ground, causing the trigger block to contact the pressure trigger head and trigger an alarm. Furthermore, the use of gravity counterweights makes the auxiliary device less demanding in terms of installation location; it only needs to be installed on the top surface inside the tower, parallel to the ground. This provides timely early warning while improving installation convenience.

[0014] 2. This wind power tower verticality monitoring auxiliary device, through its installation mechanism, allows the traction rope to be supported and connected via a support plate one during use. Using the connecting bracket, support plate two, and bolts, the monitoring auxiliary device can be installed inside the tower, thus realizing the function of installing the verticality monitoring auxiliary device.

[0026] Furthermore, the trigger block 37 is located on the side of the traction rope 35 away from the counterweight block 36, and the trigger block 37 is located inside the pressure sensor 34, so that the trigger block 37 can normally trigger the pressure trigger head 38.

[0027] Furthermore, four support rods 33 are provided, and the four support rods 33 are evenly distributed at the bottom of the connecting ring 1, which improves the stability of fixing the pressure sensor 34.
