Description

Technical Field

[0001] The utility model belongs to the technical field of wind power engineering, in particular to a wind power tower inclination early warning device. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time. Using wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world. The wind turbine tower is the tower pole of wind power generation. The wind turbine tower is an important part of the wind turbine. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. The existing wind turbine towers are generally more than 100 meters high, and they are very prone to settlement and tilt during operation.

[0003] A Chinese patent discloses a wind power tower tilt warning device (publication number CN217950598U). The patent uses a vertical holding component to keep the laser transmitter always vertical to the ground. When the tower tilts, the laser receiver also tilts, but the optical signal remains vertical to the horizontal plane. At this time, the optical signal received by the laser receiver is offset or interrupted, and it can be known that the tower is tilted. The wind power tower tilt warning device provided by the utility model has the effect of monitoring whether the tower is tilted, but when the patent is used, it needs to be powered on when the laser transmitter and the laser receiver are powered on, which makes the device overly dependent on electricity and cannot be used when it is not powered on, thereby affecting the use effect of the device and being unable to adapt to the impact of weather changes. Utility Model Content

[0004] In order to solve the problem of over-reliance on electricity in the prior art, the utility model provides a wind turbine tower tilt warning device. When the tower body tilts, the warning mechanism at the current tilt direction position will be driven to tilt accordingly, causing the first support rod, the connecting block and the push rod to tilt. When the push rod tilts, multiple first paddles will be caused to tilt and move. When the first paddle moves in the tilt direction, it will squeeze and paddle each other with the second paddle. When one end of the second paddle is subjected to force and tilts and deflects, due to a certain distance between the multiple first paddles, the second paddle that has deflected forward will deflect backward under the action of inertia. During the deflection of the second paddle, the spring will be driven to move back and forth. When the spring moves in the inertia, When the backward deviation occurs under the action, the spring will generate a rebound force, which will cause one end of the spring to contact the side of the sensing block. When the sensing block and the spring contact each other, the trigger sensor will send a sensing signal, and the sensing signal will be emitted through the positioning alarm, which can be received by the signal receiver. Due to the different positions of the first paddle on the push rod, the distance from the second paddle is also different, and the farther the distance between the first paddle and the second paddle is, the larger its size is, and the greater the tilt deviation effect on the second paddle is, and the greater the rebound force of the spring, so that the contact signal with the trigger sensor is stronger, and the tilt angle of the cylinder is judged by the strength of the signal, thereby realizing early warning of the cylinder.

[0005] To achieve the above purpose, the specific technical solution is as follows:

[0006] A wind power tower tilt warning device comprises a cylinder, a fixed base is installed at the bottom end of the cylinder, a first sleeve block is arranged at the periphery of the cylinder, a protective plate is arranged at the bottom of the first sleeve block, an early warning mechanism is arranged between the protective plate and the first sleeve block, and the protective plate is fixedly installed on the top of the fixed base through a support column;

[0007] The early warning mechanism includes a plurality of first support rods arranged at the bottom end of the first sleeve block, a push rod is arranged on the side of the first support rod, a plurality of first paddles are arranged on the periphery of the push rod, a second paddle is arranged on the side of the first paddle, a plurality of springs are arranged at the bottom end of the second paddle, and a trigger sensor for alarm positioning is arranged on the side of the spring.

[0008] Furthermore, the top of the first support rod is fixedly connected with a second sleeve block, the inner cavity of the second sleeve block is fixedly sleeved with a support ring, and the support ring is fixedly installed in the inner cavity of the bottom end of the first sleeve block.

[0009] Furthermore, a connecting block is rotatably sleeved on the bottom of the first support rod through a first bolt thread, and one end of the connecting block away from the first support rod is fixedly connected to one end of the push rod.

[0010] Furthermore, the first paddles are evenly arranged on the periphery of the push rod, and the sizes of the first paddles are different.

[0011] Furthermore, a protective frame is arranged around the periphery of the second paddle, and the top of the protective frame is rotatably connected to a rotating cover via a first rotating rod. The inner wall of the protective frame is fixedly connected to the second paddle via a supporting pad, and the inner wall of the protective frame is also fixedly connected to the side of the trigger sensor via a connecting rod.

[0012] Furthermore, a positioning alarm is fixedly installed at the bottom of the trigger sensor, a sensing block is fixedly connected to the top of the trigger sensor, the side of the sensing block is far away from one end of the spring, and the spring is fixedly installed on the side of the second paddle.

[0013] Compared with the prior art, the beneficial effects of the present invention are at least:

[0014] 1) By setting up an early warning mechanism, under the interaction between the first paddle and the second paddle, due to the different distances and sizes between the first paddle and the second paddle, different degrees of tilting and offset effects can be produced, thereby affecting the rebound force of the spring, so that the trigger sensor can judge the tilt angle of the cylinder according to the strength of the rebound force, and immediately send out an early warning signal when the tilt is detected, thereby improving the safety of the wind turbine tower.

[0015] 2) By providing a first support rod, and the first support rod and the cylinder are in a state of being parallel to each other, the tilt of the first support rod can be monitored under the action of the early warning mechanism, thereby realizing an early warning of the tilt of the cylinder.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] Example 1: Figure 1-5 As shown, the utility model aims to provide a wind power tower tilt warning device to solve the problem of over-reliance on electricity in the prior art. According to the above functions, the whole device includes a cylinder 1, a fixed base 2 is installed at the bottom of the cylinder 1, a first sleeve block 4 is arranged on the periphery of the cylinder 1, a protective plate 3 is arranged at the bottom of the first sleeve block 4, an early warning mechanism is arranged between the protective plate 3 and the first sleeve block 4, and the protective plate 3 is fixedly installed on the top of the fixed base 2 through a support column 5;

[0024] The early warning mechanism includes a plurality of first support rods 11 arranged at the bottom end of the first sleeve block 4, a push rod 16 is arranged on the side of the first support rod 11, a plurality of first paddles 17 are arranged on the periphery of the push rod 16, a second paddle 18 is arranged on the side of the first paddle 17, the first paddle 17 and the second paddle 18 are made of rubber material, which can restore to their original shape after bending and deformation, a plurality of springs 21 are arranged at the bottom end of the second paddle 18, a trigger sensor 22 for alarm positioning is arranged on the side of the spring 21, the first support rod 11 and the cylinder 1 are in a state of being parallel to each other, and whether the cylinder 1 is tilted is detected by detecting whether the first support rod 11 is tilted, thereby realizing a tilt early warning of the cylinder 1;

[0025] Specifically, the spring 21 bends as the second paddle 18 bends. When the second paddle 18 returns to its original shape, the spring 21 continues to move under the action of inertia, thereby contacting the trigger sensor 22 and transmitting a signal through the trigger sensor 22.

[0026] Example 2: Figure 1-5As shown, the top of the first support rod 11 is fixedly connected with the second sleeve block 10, the inner cavity of the second sleeve block 10 is fixedly sleeved with a support ring 9, and the support ring 9 is fixedly installed in the bottom inner cavity of the first sleeve block 4. The bottom end of the first sleeve block 4 is provided with a groove to achieve the installation and fixation of the support ring 9. The first sleeve block 4 is installed vertically to the ground and maintained in a state of being parallel to the cylinder 1. The tilt of the first sleeve block 4 is achieved by tilting the cylinder 1 to provide an early warning of the tilt.

[0027] like Figure 4-5 As shown, a connecting block 12 is threadably connected to the bottom of the first support rod 11 through a first bolt 13, and one end of the connecting block 12 away from the first support rod 11 is fixedly connected to one end of the push rod 16. By setting the first bolt 13 to connect the connecting block 12, adjustment and correction after tilting after installation can be conveniently performed.

[0028] like Figure 5 As shown, the first paddles 17 are evenly arranged on the periphery of the push rod 16, and the sizes of the plurality of first paddles 17 are different. The positions of the first paddles 17 on the push rod 16 are different, and the distances from the second paddles 18 are also different. The farther the distance between the first paddle 17 and the second paddle 18 is, the larger its size is, and thus the tilting and offset effect caused on the second paddle 18 is greater, and the rebound force generated by the spring 21 is greater.

[0029] like Figure 4 and Figure 5 As shown, a protective frame 6 is arranged on the periphery of the second paddle 18, and the protective frame 6 is fixedly mounted on the inner wall of the protective plate 3. The top of the protective frame 6 is rotatably connected to a rotating cover plate 15 via a first rotating rod 14. The rotating cover plate 15 is flippable, which can not only play a role in installation protection for the interior of the protective frame 6, but also can be inspected and corrected by flipping. The inner wall of the protective frame 6 is fixedly connected to the second paddle 18 via a support pad 19. The support pad 19 is made of rubber material and can play a protective role for the second paddle 18. The inner wall of the protective frame 6 is also fixedly connected to the side of the trigger sensor 22 via a connecting rod 8.

[0030] like Figure 2 and Figure 5 As shown, a positioning alarm 7 is fixedly installed at the bottom of the trigger sensor 22, and the positioning alarm 7 is driven by the trigger sensor 22. When the trigger sensor 22 is touched, the positioning alarm 7 will be driven, and the positioning signal will be transmitted to the receiver, so as to facilitate maintenance personnel to quickly locate the position of the cylinder 1 for emergency repairs, improve response speed and save time. A sensing block 20 is fixedly connected to the top of the trigger sensor 22, and the side of the sensing block 20 is far away from one end of the spring 21, and the spring 21 is fixedly installed on the side of the second paddle 18.

[0031] The specific working principle of this device: when it is necessary to use this device to warn whether the wind turbine tower is tilted, first of all, it is necessary to install this device vertically so that the first support rod 11 remains perpendicular to the ground. When the cylinder 1 tilts, it will drive the warning mechanism at the current tilt direction to tilt accordingly, causing the first support rod 11, the connecting block 12 and the push rod 16 to tilt. When the push rod 16 tilts, multiple first paddles 17 will tilt and move. When the first paddle 17 moves in the tilting direction, it will squeeze and paddle the second paddle 18. When one end of the second paddle 18 is forced to tilt and deflect, due to a certain distance between the multiple first paddles 17, the second paddle 18 that has shifted forward will shift backward under the action of inertia. During the displacement of the second paddle 18, the spring 21 will be driven to When the spring 21 moves backward under the action of inertia, the spring 21 will generate a rebound force, so that one end of the spring 21 contacts the side of the sensing block 20. When the sensing block 20 and the spring 21 contact each other, the trigger sensor 22 will send a touch signal, and the touch signal will be transmitted through the positioning alarm 7, so that it can be received by the signal receiver. Due to the different positions of the first paddle 17 on the push rod 16, the distance from the second paddle 18 is also different, and the farther the distance between the first paddle 17 and the second paddle 18 is, the larger its size is, and the greater the tilting offset effect caused to the second paddle 18, and the greater the rebound force of the spring 21, so that the contact signal with the trigger sensor 22 is stronger, and the tilt angle of the cylinder 1 is judged by the strength of the signal, thereby realizing early warning of the cylinder 1.
