[0002] In today's rapidly developing industrial background, the number of high-rise and long-span structures such as cable structure bridges and super high-rise buildings is rapidly increasing. While these structures provide more space and convenience, they also face the challenge of vibration. Compared with traditional buildings, super high-rise buildings have higher flexibility and larger wind area, making them more susceptible to adverse vibration under strong wind and other dynamic loads. Such vibration not only affects the comfort of the building, but also can have a serious impact on its structural safety and durability.

[0003] The dynamic behavior of high-rise and long-span structures is more complex than that of rigid structures because their vibration frequencies are lower and they are more prone to resonance. For example, when a super high-rise building encounters strong winds, the swaying at the top can cause vibrations to be transmitted downward, affecting the stability of the entire structure. In order to solve these problems, the research and application of vibration control technology are particularly important.

[0035] As shown in the accompanying drawings of the specification Figure 1 The present application provides a device for suppressing adverse vibration of engineering structure, comprising: a water inlet pipe 1 for providing water source for the device, a core control system assembly box 2, and high-pressure nozzles 3 for releasing high-pressure water flow and providing reaction force against wind vibration for the building.

[0036] The control system assembly box 2 comprises a water tank 21, a six-axis sensor 22 and a control system 23, the water tank 21 temporarily stores part of water, the six-axis sensor 22 identifies the acceleration and inclination angle in each direction and converts them into electrical signals, the signals are transmitted to the control system 23 by identifying the acceleration and inclination direction of the structure under the action of wind vibration, the control system 23 identifies the signals and executes the command to open the corresponding high-pressure nozzles 3 to release high-pressure water flow and provide reaction force against the action of wind vibration, thereby achieving the effect of suppressing vibration.

[0037] The water inlet of the water tank 21 is connected with the water inlet pipe 1, the water outlet of the water tank 21 is communicated with the high-pressure nozzles 3 through a high-pressure water pipe 6, and the control system 23 is electrically connected with the six-axis sensor 22 and the high-pressure nozzles 3 through a sensor and control system connecting line 4 and a control system and nozzle connecting line 5, respectively. A water pump is arranged in the water tank 21.

[0038] The high-pressure nozzles 3 are arranged in several groups, a single group of high-pressure nozzles 3 comprises three nozzles with different orientations, which are a horizontal high-pressure nozzle 32, an upward high-pressure nozzle 33 and a downward high-pressure nozzle 31, the water flow directions of the upward high-pressure nozzle 33 and the downward high-pressure nozzle 31 are on the same straight line, and the water flow direction of the horizontal high-pressure nozzle 32 is perpendicular to the water flow directions of the upward high-pressure nozzle 33 and the downward high-pressure nozzle 31. The orientation of the high-pressure nozzles 3 is adjusted by the water pressure of the nozzles in three directions to cope with wind vibration in different directions.

[0039] The present application also provides a use method of the above-mentioned device for suppressing adverse vibration of engineering structure, comprising the following steps:

[0040] S1, calculating the number of the water inlet pipe 1, the control system assembly box 2 and the high-pressure nozzles 3 according to the internal space of the building;

[0041] S2, laying the water inlet pipe 1 to the building, placing the high-pressure nozzles 3 in the edge gap of the building, and placing the control system assembly box 2 in the interior of the building;

[0042] S3, debugging and assembling the water inlet pipe 1, the control system assembly box 2 and the high-pressure nozzles 3.

[0043] In step S3, the debugging process includes:

[0044] The six-axis sensor 22 identifies the acceleration and tilt direction of the structure under wind vibration. The six-axis sensor 22, by integrating a three-dimensional acceleration sensor and a three-dimensional gyroscope, can simultaneously measure the acceleration and angular velocity of an object in three spatial dimensions, thereby providing complete motion and attitude data. The acceleration sensor measures the acceleration of the object based on the principle of inertia, while the gyroscope measures the angular velocity of the object. The two combined can accurately calculate the motion state and rotation angle of the device. Through data fusion algorithms such as complementary filtering or Kalman filtering, the six-axis sensor 22 can provide real-time attitude estimation for attitude control and motion detection. The signals are transmitted to the control system 23, which identifies and judges the signals and issues commands to open the corresponding high-pressure nozzles 3, which release high-pressure water flow.

[0045] The high-pressure nozzles 3 are symmetrically arranged, with two symmetric groups of high-pressure nozzles 3 arranged on the same straight line. When vibrations occur in a certain direction, the high-pressure nozzles 3 in that direction are assisted by high-pressure nozzles 3 on the opposite side of the structure, achieving double the reaction force. The size of this force can be adjusted through the signals received by the six-axis sensor 22. This device is suitable for suppressing a variety of different types of vibrations, greatly saving design costs.

[0046] Embodiment One

In this embodiment, four groups of high-pressure nozzles 3 are arranged on a single bridge structure 7, at the edge gaps of the bridge structure 7.

[0048] A single control system assembly box 2 contains a water tank 21, a six-axis sensor 22, and a control system 23. When the bridge is subjected to wind vibration from left to right, the six-axis sensor 22 will receive motion signals and send them to the control system 23. Then, the control system 23 will open the three-way high-pressure nozzles 3 according to the signal category. The water in the water tank 21 is pressurized by the water pump and sprayed out from the downward high-pressure nozzles 31 and the horizontal high-pressure nozzles 32 through the high-pressure water pipe 6. At the same time, the upward high-pressure nozzles 33 on the opposite side of this side will also react, forming a counteracting force against the wind vibration. The size of this counteracting force can be adjusted by the strength of the signals received by the six-axis sensor 22, thereby ensuring the stability of the bridge structure 7.

In this embodiment, eight groups of high-pressure spray heads 3 are arranged on the axial surface of the wind power tower 8, and are arranged at the edge gap of the wind power tower 8.

[0051] The single control system assembly box 2 contains a water tank 21, a six-axis sensor 22 and a control system 23. When the wind power tower 8 is subjected to wind vibration from left to right, the six-axis sensor 22 will receive a motion signal and send it to the control system 23, and then the control system 23 will open the three-way high-pressure spray head 3 according to the signal category. The water in the water tank 21 is pressurized by the water pump and sprayed out from the downward high-pressure spray head 31 and the horizontal high-pressure spray head 32 through the high-pressure water pipe 6. At the same time, the upward high-pressure spray head 33 on the opposite side will also react to form a counterforce to resist the wind vibration, and the size of the counterforce can be adjusted by the signal strength received by the six-axis sensor 22, so as to ensure the stability of the wind power tower 8.
