Problems solved by technology

[0002] At present, there are many methods applied to structural vibration control, mainly including active control, passive control, semi-active control and hybrid control, etc., but most of these control methods use energy-consuming components to absorb the vibration energy of the structure or use external energy to offset the vibration energy of the structure. , so passive control has unsatisfactory control effect, and energy-consuming components fail due to energy absorption; active control has problems such as large energy required and difficult to realize, and reliability is not suitable to be guaranteed

Embodiment 1

[0020] The vibration isolation energy conversion control device of the present invention is as figure 1 As shown, the bottom of the building structure 1 is composed of the upper base plate 2 of the seismic isolation layer, the lower base plate 3 of the seismic isolation layer, the airbag hydraulic accumulator 6, the overflow valve 7, the three-position four-way electromagnetic reversing valve 8, the hydraulic pressure Oil cylinder 9, hydraulic cylinder piston 10, one-way valve 12-15, and hydraulic tank 16-19 are composed.

[0021] The internal structure of the transducer is as figure 2 As shown, the hydraulic cylinder 9 is divided into A cylinder 24 and B cylinder 25 by the piston. The A cylinder 24 is connected with check valves 12 and 14. The check valve 12 is connected with the hydraulic tank 16. Device 6 is connected; B cylinder 25 is connected with check valve 13,15, and check valve 13 is connected with hydraulic tank 17, and check valve 15 is connected with air bag typ...

Embodiment 2

[0023] Working status of vibration isolation and energy conversion:

[0024] Such as figure 2 As shown, when the three-position four-way electromagnetic reversing valve 8 is in the middle cut-off position, the oil circuit connected with the three-position four-way electromagnetic reversing valve 8 does not flow. When the structural vibration drives the piston 10 of the hydraulic cylinder 9 to move to the right relative to the hydraulic cylinder 9, the volume of the chamber A 24 increases and the pressure decreases, so that the one-way valve 12 is opened, the one-way valve 14 is closed, and the hydraulic oil is drawn from the hydraulic tank 16 At the same time, the volume of B chamber decreases, the pressure increases, the one-way valve 15 opens, the one-way valve 13 closes, and the hydraulic oil is pressed into the air bag hydraulic accumulator 6 from B chamber 25 , thus realizing the conversion of kinetic energy of structural vibration into hydraulic energy. The flow direc...

Embodiment 3

[0026] Actively control working status:

[0027] According to the needs of structural response information and vibration control, the energy conversion control device can also play a control role, that is, use the high-pressure oil stored in the accumulator 6 as an energy source, and control it by the hydraulic cylinder through the control of the three-way four-position electromagnetic reversing valve 8 9 Apply forces to the structure. The structural response information is transmitted to the computer 5 through the structural response information sensor 4, and the computer 5 controls the operation of the three-way four-position electromagnetic reversing valve 8.

[0028] When the piston 10 of the hydraulic cylinder 9 needs to apply a force to the right, the three-way four-position electromagnetic reversing valve 8 can connect the airbag hydraulic accumulator 6 with the A chamber 24. At this time, the oil pressure of the A chamber 24 is very high. At the same time, the chamber...
