According to Taiwan's geographical location, it is located at the junction of the Philippine Sea Plate and the Eurasian Plate. Due to collisions between the plates, earthquakes often occur in various regions of Taiwan. According to observations and statistics from 2001 to 2015 by the Central Meteorological Administration, each year On average, there are about 26,000 earthquakes in Taiwan, including about 1,000 sensitive earthquakes. As long as the magnitude of the earthquake reaches 4 or more, it may cause the collapse of furniture, even cracks on the wall, and damage to the structure of the building. Many major earthquakes in the past have caused many buildings to collapse, and even caused a large number of civilian casualties. Therefore, in Taiwan, where earthquakes occur frequently, people have become increasingly demanding of the earthquake resistance of buildings. It also specifies the specifications for earthquake resistance.

In terms of the current seismic methods, three methods of earthquake resistance, isolation, and damping are used in general buildings. No matter which seismic method is used, 25% of the seismic energy must be eliminated before it can be called effective earthquake resistance. Modern public buildings generally adopt the construction method of seismic isolation and seismic isolation. The seismic isolation method is to install one or more isolators between floors to reduce the seismic energy transmitted from the ground. The seismic isolation method is Retrofit The "seismic wall" or "damper" on the walls of each floor of the building can offset the seismic energy, reduce the amplitude of the earthquake, and effectively prevent the building structure from being damaged. The construction cost of the seismic isolation method will be relatively low. Seismic construction method is high, so construction engineering is still mainly based on seismic construction method.

The damper used in the seismic damping method needs a controller to be able to flexibly respond to earthquake activities, such as the Republic of China Patent Publication No. TW 593908B "semi-active hydraulic damper", which provides a semi-active hydraulic damper. Active control method, in which the directional control valve is a four-port three-position solenoid valve. After detecting the magnitude and direction of the vibration by the vibration sensor, the solenoid valve is excited so that the directional control valve can be pushed left or right to control each valve. The switching of the position prevents the hydraulic oil from flowing to maintain the structure of the building. However, this type of directional control valve using a solenoid valve is actuated by electric excitation and is usually used together with other electronic components. However, complex electronic components will cause a delay in response time and a high probability of damage. In the case of low maintenance frequency, the damage of solenoid valves and other electronic components is not easy to detect. Therefore, when the earthquake suddenly comes, the damage of the circuit will make the damper unable to operate effectively, reducing the protection of the building structure. Therefore, how to improve the way of controlling the damper and reduce the damage rate of the controller is the research direction of the inventors.

Position so that the connected damper can offset the external force that changes the distance between the first node and the second node.

The purpose of the present invention and its structural and functional advantages will be explained based on the structure shown in the following drawings, in conjunction with specific embodiments, so that the reviewing committee can have a deeper and more specific understanding of the present invention.

Please refer to the first figure and the second figure. The autonomous seismic controller of the present invention includes a valve body structure (1), which has a first control section (11) and a second control section (12). And a central valve position (14), the first control part (11) is connected to the central valve position (14), and the central valve position (14) is then connected to the second control part (12), and further, the first control part (11) and the second control unit (12) are hydraulic control, and there are oil channels inside for hydraulic oil to flow, and a miniature piston (13) is provided, and the central valve position (14) can be four-port three-position or Four-port two-position equal-valve structure; a hydraulic cylinder assembly (2), which includes a cylinder block (21), a first node (22), and a second node (23). Inside there is a piston (212) penetrating a sliding rod (211). One end of the sliding rod (211) protrudes from the outside of the cylinder (21) and extends to connect the first node (22) and the second node (23). It is set outside the cylinder block (21) relative to the first node (22), where the cylinder block (21) contains hydraulic oil, and the area of the piston (212) is 10 to the area of the micro piston (13) in the control section. 1000 times; and the primary circuit unit (3) with a first oil The circuit (31) communicates with the hydraulic oil inside the cylinder block (21) and the first control section (11), and a second oil path (32) communicates with the hydraulic oil inside the cylinder block (21) and the second control section ( 12) In addition, a relief valve device is further provided (34) and a third oil passage (33) are connected to the relief valve device (34) and the cylinder block (21) through the third oil passage (33), wherein the third oil passage (33) and the first oil passage (33) The oil passage (31) and the second oil passage (32) communicate with each other to form a circuit.

In addition, the autonomous anti-vibration controller system of the present invention can be combined with a hydraulic damper (4) to form a vibration damping module; and the hydraulic damper (4) system can include, for example, a cylinder body (41) with A piston (412) is provided with a sliding rod (411). One end of the sliding rod (411) protrudes from the outside of the cylinder (41), and extends to connect to an elastic body (42), and then to the third node (43). ), And a fourth node (44) is disposed outside the cylinder (41) opposite the third node (43).

Thus, the independent seismic controller of the present invention can be combined with a hydraulic damper and installed at the fulcrum at both ends of the building. When an earthquake occurs, the valve body structure (1) can be based on the first node of the cylinder body (21). The distance between (22) and the second node (23) changes to control the action of the central valve position (14) to offset the energy of the external force.

In addition, through the following specific examples, the scope of the present invention can be further proved, but it is not intended to limit the scope of the present invention in any form.

Previous semi-active control systems usually had speed positive and negative sensors (judging speed positive and negative based on displacement increase and decrease), control computer (responsible for signal processing, predictive analysis, control law execution and control signal generation), switch controller (responsible for switching The solenoid valve) and the electromagnet in the solenoid valve are four important components. The electronic components are used to control the damper. The flow of its action is to first convert the force into deformation energy, and then the deformation energy is converted by the positive and negative speed sensors. When it is converted to electric energy, the control computer will generate a series of calculations and switching actions. Finally, the electric power will generate the power to push the switch controller of the directional control valve to make the solenoid valve actuate. These actions are the only places where semi-active control requires external energy (electricity) supply, but they are also the main source of time delay for semi-active control. In the case of different seismic waves, the time delay of the control system will cause the damper to respond less well, thereby reducing the effect of protecting the building structure.

According to this, please refer to the first and second figures. The first control part (11) and the second control part (12) of the valve body structure (1) of the autonomous seismic controller of the present invention are hydraulically controlled. There is an oil circuit for the hydraulic oil to flow, and a micro piston (13) is individually provided, and the first control part (11) and the second control part (12) are provided on both sides of the central valve position (14). 14) It can be a four-port three-position or four-port two-position control valve, such as the four-port three-position neutral pass valve position, neutral stop valve position, or four-port two-position control valve, etc. The inflow of hydraulic oil from the first control section (11) or the second control section (12) will push the central valve position (14) to the correct position. In the present invention, the control unit with full hydraulic pressure control eliminates the energy conversion process and directly transmits the force of the hydraulic oil to the central valve position (14), thereby achieving the control effect and completely eliminating the dependence on external energy (electricity). , Can avoid the loss of time delay and produce better shock absorption effect.

Furthermore, the hydraulic cylinder assembly (2) includes a cylinder block (21), a first node (22) and a second node (23). Generally speaking, the first node (22) and the second node (23) ) Will be fixed to the fulcrum of the main structure and the substructure respectively, and a piston (212) penetrating a slide rod (211) is arranged inside the cylinder body (21), and one end of the slide rod (211) protrudes from the cylinder body ( Outside 21), the second node (23) is arranged on the cylinder block (21), which is opposite to the first node (22). The cylinder block (21) contains hydraulic oil, and the piston (212) The area of the piston is 10 to 1000 times the area of the miniature piston (13). Therefore, as long as the piston (212) is affected by a little displacement, the energy can be transmitted to the miniature piston (13). It has a large displacement magnification and can be effectively used. Controls the amount of delay displacement.

Except for the valve body structure (1) and the hydraulic cylinder assembly (2), the entire structure must be connected in series by the circuit unit (3) to control. Therefore, the circuit unit (3) is connected by the first oil circuit (31) The hydraulic oil inside the cylinder block (21) is connected to the first control part (11), and the second oil path (32) is connected to the hydraulic oil inside the cylinder block (21) and the second control part (12). In addition, the circuit unit (3) is provided with an overflow mechanism, which is connected to the overflow valve device (34) and the cylinder block (21) through the third oil path (33). After the valve position is switched, the circuit unit (3) Reach the preset overflow Flow pressure, it will not increase the pressure on the valve body structure (1), and the hydraulic oil will be gradually relieved by the relief valve device (34), so that the pressure of the central valve position (14) will not be absent. Stop rising and be damaged.

Please refer to the fourth figure again. The autonomous anti-vibration controller system of the present invention can be combined with a hydraulic damper to form a vibration damping module. Taking a common damper as an example, the hydraulic damper (4) system It may include, for example, a cylinder block (41), a piston (412) passing through a slide rod (411) inside, and one end of the slide rod (411) protrudes from the outside of the cylinder block (41) and extends to an elastic connection. Body (42) and a third node (43), and a fourth node (44) is arranged outside the cylinder body (41) opposite to the third node (43); the portion of the loop unit (3) will provide additional oil The road communicates the hydraulic oil inside the cylinder block (41) with the central valve position (14) of the valve body structure (1).

In actual operation, for example, when an earthquake occurs, the time point when the relative movement direction of the first node (22) and the second node (23) changes is detected. When the first node (22) starts to move away from the second node (23), the slider (211) will be pulled closer to the first node (22), and the pressure of the right oil chamber in the cylinder block (21) will increase. An oil circuit (31) sends hydraulic oil to the first control section (11), and the first control section (11) generates a pressure to push the central valve position (14) to the left, which means using a piston (212) Drive the micro piston (13) to change the position of the central valve position (14). When the first node (22) stops moving away from the second node (23), and starts to turn and approaches the second node (23), the pressure of the left oil chamber in the cylinder block (21) will rise, and the second oil The road (32) sends hydraulic oil to the second control section (12), and the second control section (12) generates a pressure to push the central valve position (14) to the right. When the direction is changed, the slide rod (211) can immediately drive the micro piston (13), causing it to slide backwards to complete the action of switching the central valve position (14). In this way, the valve body structure (1) moves in the building structure. It is switched once when the direction is reversed.

However, the distance between the third node (43) and the fourth node (44) of the original hydraulic damper (4) should also change. However, due to the change of the central valve position (14) controlled by the present invention, The hydraulic oil in the right or left oil chamber of the cylinder block (41) cannot flow, so the piston (412) and the slide rod (411) are fixed, so that the third node (43) and the fourth node ( 44) The movement of the fulcrum of the connected building is all transformed into the deformation of the elastic body (42), and the elastic force generated by this deformation is opposite to the relative displacement direction of the third node (43) and the fourth node (44), so that It exerts the greatest negative work on the structure, that is, dissipates energy, thereby protecting the structure of the building from damage.

As can be seen from the foregoing implementation description, compared with the prior art, the present invention has the following advantages:

1. When the distance between the first node and the second node of the hydraulic cylinder assembly becomes longer or shorter according to the autonomous seismic controller of the present invention, the first control part or the second control part of the valve body structure receives the hydraulic oil. Pushing, the central valve position can be smoothly operated to move to the correct position, so that the combined damper can offset the external force that changes the distance between the first node and the second node.

2. The valve body structure of the autonomous anti-vibration controller of the present invention is a full hydraulic device. The action of the hydraulic damper can be controlled by hydraulic oil. Compared with the previous controller, a variety of electronic components are used, and it is easy to damage. In the absence of the valve, the full-hydraulic valve body structure of the present invention has a low damage rate. When an earthquake suddenly comes, the damper can be effectively operated to protect the structure of the building.

3. The piston area of the hydraulic cylinder assembly of the autonomous anti-vibration controller of the present invention is 10 to 1000 times the area of the miniature piston, so as long as the piston is affected by a little displacement, the energy can be transmitted to the miniature piston. The displacement magnification can effectively control the amount of delayed displacement and make the overall response speed more sensitive to offset more seismic energy.

In summary, the autonomous anti-vibration controller of the present invention can indeed achieve the expected use effect through the embodiments disclosed above, and the present invention has not been disclosed before the application, and it has fully complied with the provisions of the Patent Law. With requirements. Proposed invention patent I would like to apply for the examination and grant the patent, which is really a virtue.
