[0002] The deep-sea reef environment is harsh, with problems such as frequent typhoon climates and difficult supervision. Functional structures that can reduce the structural natural vibration period and dissipate energy in multiple directions are required to cope with various emergencies.

[0057] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0059] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0060] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] Such as Figures 1 to 9As shown in the figure, an embodiment of the present application provides a damping device for an island reef sentry post building, including: a fixed seat 1, a rotating seat 2, a rotating energy dissipator 3, and a plurality of linkage rods 4. The building generally includes columns 9 and cross beams 8 connecting the columns 9. The fixed seat 1 can be connected to the cross beam 8 of the building, the rotating seat 2 is rotatably connected to the fixed seat 1, and a plurality of lifting guide grooves 221 are arranged on the rotating seat 2. Each lifting guide groove 221 is sequentially arranged at intervals along the circumferential direction of the rotating seat 2, and the lifting guide groove 221 extends along the radial direction of the rotating seat 2. The rotating energy dissipator 3 is arranged on the fixed seat 1 or the rotating seat 2. One end of each linkage rod 4 is respectively connected to the column 9 of the building, and the other end of each linkage rod 4 is respectively slidably connected to the corresponding lifting guide groove 221 on the rotating seat 2.

[0062] In the state where the linkage rod 4 pushes the rotating seat 2 to rotate around the fixed seat 1, the rotating energy dissipator 3 can elastically abut against the rotating seat 2 or the fixed seat 1 to dissipate the external impact energy. In the state where the linkage rod 4 slides along the lifting guide groove 221, the linkage rod 4 can move along the arrangement direction of the fixed seat 1 and the rotating seat 2, that is, move along the thickness direction of the rotating seat, and abut against the fixed seat 1 to dissipate the external impact energy. The damping device of the present application has a multi-directional energy dissipation effect and reduces the torsional vibration period of the building.

[0063] The damping device of the island reef sentry post building provided by the embodiment of the present application can be applied to high-rise sentry post buildings on deep-sea island reefs. The damping device of the island reef sentry post building provided by the present application has the advantages of reducing the natural vibration period of the building and being convenient for disassembly and assembly, and has good adaptability to the anti-typhoon building supporting facilities of high-rise sentry post buildings on typhoon-prone islands.

[0064] In some possible implementation schemes, the fixed seat 1 includes an elastic plate and a bottom plate 15. The bottom plate 15 and the elastic plate are arranged at intervals and are connected to each other. A gap is formed between the bottom plate 15 and the elastic plate. The rotating seat 2 is rotatably arranged in the gap. The lifting guide groove 221 is arranged on the surface of the rotating seat 2 facing the elastic plate. A friction block 411 is arranged at the end of the linkage rod 4. One end of the linkage rod 4 is located between the rotating seat 2 and the elastic plate, and the friction block 411 is slidably accommodated in the lifting guide groove 221. In the state where the friction block 411 slides along the lifting guide groove 221, the linkage rod 4 moves along the thickness direction of the rotating seat to squeeze or move away from the elastic plate, and the elastic plate absorbs the external impact energy to protect the building structure and prevent the building structure from being severely damaged. The friction block 411 slides to different heights of the lifting guide groove 221 according to the amplitude of the building structure, generating different energy dissipation values.

[0065] In some possible implementation schemes, such as Figure 2 、 Figure 7 and Figure 8As shown, in the direction from the middle to both ends of the lifting guide groove 221, the groove depth of the lifting guide groove 221 gradually decreases. That is, along the radial direction of the rotating base 2, the groove depth in the middle of the lifting guide groove 221 is large, and the groove depths on both sides gradually decrease. When there is no external impact (such as no typhoon), the friction block 411 provided at the end of the linkage rod 4 is located in the middle of the lifting guide groove 221, and there is a gap between the linkage rod 4 and the elastic plate, or although they are in contact, the extrusion force is small. When the building deforms, it can drive the linkage rod 4 to move synchronously, and the friction block 411 can slide along the lifting guide groove 221 from the middle to one side (any side). During this process, the end of the linkage rod 4 will gradually rise and elastically abut against the elastic plate, and the elastic plate absorbs energy to resist the external impact force.

[0066] In some possible implementation schemes, the rotating base 2 includes a main board body 21, a plurality of sliding friction devices 22 and a plurality of guide shells 23. Each sliding friction device 22 is arranged on one side of the main board body 21 close to the elastic plate. The sliding friction devices 22 are sequentially arranged at intervals along the circumferential direction of the main board body 21. The lifting guide groove 221 is arranged on the sliding friction device 22. Each guide shell 23 is respectively connected to the corresponding sliding friction device 22. The guide shell 23 has a lifting groove, and the lifting groove extends along the thickness direction of the rotating base 2, and the lifting groove extends from the sliding friction device 22 to the elastic plate. The linkage rod 4 has a rod portion, and the friction block 411 is connected to the rod portion. The rod portion is slidably received in the lifting groove, and the friction block 411 is slidably received in the lifting guide groove 221. When the friction block 411 slides along the lifting guide groove 221, it will rise and fall, and the rod body of the linkage rod 4 will slide up and down along the lifting groove, squeezing or releasing the elastic plate, and the elastic plate will correspondingly apply a corresponding reverse pressure.

[0067] The sliding friction device 22 can be a rectangular steel plate with a lifting guide groove 221. Rectangular steel plates with different roughnesses can be replaced according to the energy consumption requirements, and the friction energy consumption value can be independently changed according to the building side displacement value. The greater the displacement of the strut under the extrusion of the elastic plate, the greater the extrusion force, the greater the friction force, and the more the friction energy consumption.

[0068] In some possible implementation schemes, in combination Figure 7 and Figure 8 As shown, a lifting guide groove 221 can be arranged on each sliding friction device 22. The lifting guide groove 221 includes a plurality of slit grooves arranged in parallel. The slit grooves are narrow slit grooves with a deep middle and gradually shallowing on both sides. The friction block 411 includes a plurality of friction plates, and each friction plate is respectively embedded in the corresponding narrow slit groove. Thereby, the friction contact surface between the friction block 411 and the sliding friction device 22 is increased.

[0069] The friction plate can be semi-circular. Friction plates with different roughnesses can be replaced according to the building energy consumption requirements to change the friction energy consumption value. The semi-circular friction plate can be used to consume energy through friction sliding with the lifting guide groove 221 on the rotating base 2.

[0070] In some possible embodiments, in combination with Figure 3 and Figure 4 As shown, the elastic plate includes a first plate body 11, a second plate body 12, an elastic sheet 13, and a compression alarm 14. The compression alarm 14 is located at the edge of the elastic sheet and is connected to the elastic sheet 13. The elastic sheet 13 is located between the first plate body 11 and the second plate body 12. A gap is formed between the second plate body 12 and the bottom plate 15. When the elastic sheet is compressed, the compression alarm 14 can be triggered to give an alarm. In the embodiment of the present application, by providing the compression alarm 14 on the elastic sheet 13, an alarm can be triggered when the elastic sheet 13 is compressed, timely warning of the damage caused by the vibration of the building and improving the safety of the building. A groove 131 can be provided at the edge of the elastic sheet 13 to facilitate the assembly of the compression alarm 14.

[0071] In combination with Figure 4 and Figure 5 As shown, the elastic sheet 13 can be a rubber plate. The compression alarm 14 is installed in the groove 131 at the edge of the rubber plate. When the building vibrates, it will cause the linkage rod 4 to press against the elastic plate, that is, press against the rubber plate. When the pressing force reaches a certain level, the rubber plate deforms severely, which will cause the compression alarm 14 to transmit an alarm signal. The structural design of the present application improves the safety redundancy of the building and can timely warn of the damage that the building is about to incur.

[0072] As Figure 5 and Figure 9 As shown, the compression alarm 14 can include an alarm body 141 and a compression sensor 142. A groove 131 is provided at the edge of the elastic sheet 13. The compression sensor 142 is disposed in the groove 131, while the alarm body 141 is located at the edge of the elastic sheet 13 and is fixed to the edge of the elastic sheet 13 by means of bonding or fastening connection. When the building vibrates, it will cause the linkage rod 4 to press against the elastic plate, that is, press against the elastic sheet 13. When the pressing force reaches a certain level, the elastic sheet 13 deforms severely, which will trigger the compression sensor 142, causing the compression sensor 142 to send an alarm signal.

[0073] In some possible embodiments, both the elastic plate and the rotating seat 2 can be polygons, and sliding friction devices 22 and linkage rods 4 can be provided at the positions corresponding to each side of the polygon of the damping device.

[0074] In some possible embodiments, the damping device of the reef sentry building includes a plurality of connecting rods 6. A plurality of arc-shaped grooves 24 are provided on the rotating base 2. Each arc-shaped groove 24 extends along the circumferential direction of the rotating base 2, and the arc-shaped grooves 24 are arranged at intervals in sequence along the circumferential direction of the rotating base 2. Each connecting rod 6 penetrates through the arc-shaped groove 24, the bottom plate 15 and the elastic plate of the rotating base 2. A first side limiting member and a second side limiting member are provided on the connecting rod 6. The first side limiting member and the second side limiting member are respectively limited to the bottom plate 15 and the elastic plate. When the rotating base 2 rotates relative to the fixed base 1, the connecting rod 6 slides along the arc-shaped groove 24.

[0075] The damping device of the reef sentry building may further include a central axis, and the central axis penetrates through the elastic plate, the bottom plate 15 and the rotating base 2. The rotating base 2 can rotate around the central axis. Each connecting rod 6 is located on the circumferential side of the central axis. Circular holes are provided on both the elastic plate and the bottom plate 15, and the connecting rod 6 penetrates through the opposite circular holes of the two, and the elastic plate and the bottom plate 15 cannot rotate relative to each other. The connecting rod 6 can be a screw rod, and the first side limiting member and the second side limiting member can both be nuts, which are threadedly connected to the connecting rod 6. By screwing the first side limiting member and the second side limiting member, the tightness between the elastic plate, the bottom plate 15 and the rotating base 2 can be adjusted.

[0076] It should be noted that the first side limiting member is the limiting member at the top. Both the fixed base 1 and the rotating base 2 are located below the cross beam 8. The connecting rod 6 can penetrate through the cross beam 8 of the building, and the first side limiting member can be located above the cross beam 8.

[0077] In some possible embodiments, in combination Figure 4 and Figure 8 As shown, the rotary energy dissipator 3 is arranged on the rotating base 2 and is located at both ends of the arc-shaped groove 24. When the rotating base 2 rotates relative to the fixed base 1, the connecting rod 6 can abut against the rotary energy dissipator 3.

[0078] The rotary energy dissipator 3 can be provided with a rotary alarm. The rotary alarm includes a push rod extending out of the rotary energy dissipator 3, and a U-shaped member is arranged at the end of the push rod. When the rotating base 2 rotates relative to the fixed base 1, the connecting rod 6 can move into the U-shaped member, apply an effective force to the rotary energy dissipator 3, and at the same time trigger the rotary alarm to alarm. For example, when the push rod of the rotary alarm is subjected to a certain value of extrusion force, the rotary alarm is triggered to transmit an alarm signal. The rotary alarm cooperates with the compression alarm to improve the safety redundancy of the building and timely warn of the damage that the building is about to generate.

[0079] In some possible embodiments, as Figure 4 shown, a ball 5 is arranged between the rotating base 2 and the bottom plate 15. The bottom plate 15 can be a circular structure, and a retaining edge is arranged on the circumferential side edge to prevent the ball 5 from falling out. The upper and lower sides of the ball 5 are respectively in contact with the bottom plate 15 and the rotating base 2, converting the sliding friction between the rotating base 2 and the bottom plate 15 into rolling friction, and reducing the friction loss between the two.

[0080] In some possible embodiments, the damping device of the reef sentry post building may include a torque energy dissipator 7. The torque energy dissipator 7 is located between the rotating seat 2 and the fixed seat 1 and is respectively connected to the rotating seat 2 and the fixed seat 1. When the rotating seat 2 rotates relative to the fixed seat 1, the deformation amount of the torque energy dissipator 7 increases.

[0081] The damping device of the reef sentry post building may include a plurality of torque energy dissipators 7, and the torque energy dissipators 7 are sequentially arranged at intervals around the circumference of the rotating seat 2. When the building twists under an external impact, the rotating seat 2 will be driven to rotate through the linkage rod 4, and the torque energy dissipator 7 will be stretched to dissipate energy, improving the natural vibration period of the building, increasing the energy dissipation through segmented energy dissipation of the building's energy dissipation path. When the natural vibration period of the building is too large, the compression alarm 14 and the rotation alarm will be stressed more and transmit an alarm signal to trigger an alarm, warning in time of the damage caused by the vibration of the building and improving the safety of the building.

[0082] Both the rotating seat 2 and the elastic plate may be polygonal plate structures. The torque energy dissipator 7 may be arranged at each corner of the rotating seat 2 and the elastic plate. Hinge supports may be provided at the corners of the rotating seat 2 and the elastic plate. The torque energy dissipator 7 may be a rigid spring or other damper that dissipates energy through stretching. Both ends of the torque energy dissipator 7 are respectively connected to the hinge supports at the corners of the rotating seat 2 and the elastic plate. When the rotating seat 2 rotates and dislocates relative to the elastic plate, it will cause the torque energy dissipator 7 to generate stretching energy dissipation.

[0083] In some possible embodiments, the linkage rod 4 includes a spring rod 42, a first support rod 41, and a second support rod 43. The spring rod 42 is located between the first support rod 41 and the second support rod 43 and is respectively connected to the first support rod 41 and the second support rod 43. The first support rod 41 is slidably connected to the lifting guide groove 221, and the second support rod 43 is used to connect to the building column 9.

[0084] Both the first support rod 41 and the second support rod 43 may be hollow steel pipes, and the second support rod 43 may be fixed to the building column 9 through a special-shaped fixing steel member 431. In this application, a plurality of linkage rods 4 are provided, and each linkage rod 4 extends in a different direction, thereby improving the energy dissipation efficiency. The support rods are connected by a rigid spring rod 42, which can adapt to different vibration directions of the building. Moreover, the spring rod 42 has a certain energy dissipation effect, and in cooperation with the friction block 411, segmented energy dissipation can be achieved, improving the anti-vibration ability of the building.

[0085] The present invention also provides a construction method for the damping device of the above-mentioned reef sentry post building, which mainly includes the following steps:

[0086] Step S10: Connect the linkage rod 4 to the top of the column 9 through the special-shaped fixing steel member 431;

[0087] Step S20: Install the piezoresistor in the pressure alarm 14 into the reserved groove of the elastic sheet 13 (rubber sheet), then clamp the elastic sheet 13 between two hexagonal steel plates 8 (the first plate body 11 and the second plate body 12), and connect it to the floor slab or cross beam 8 of the building through a connecting rod 6 (such as a bolt);

[0088] Step S30: Pass the rotating seat 2 through the connecting rod 6 through the arc-shaped groove 24, then insert the end of the linkage rod 4 with a friction plate into the lifting guide groove 221 of the sliding friction device 17, and clamp it by the elastic plate and the rotating seat 2;

[0089] Step S40: Install the rotary energy dissipator 3 on the rotating seat 2 on both the left and right sides of the connecting rod 6, so that the push rod of the rotary energy dissipator 3 is aligned with the sliding direction of the connecting rod 6;

[0090] Step S50: Install the torque energy dissipator 7 on the hinge support at the corner of the elastic plate and the rotating seat 2 to connect the elastic plate and the rotating seat 2;

[0091] Step S60: Place a number of balls 5 on the bottom plate 15, then connect the bottom plate 15 to the bottom of the rotating seat 2 through the connecting rod 6, and let the balls 5 contact the rotating seat 2.

[0092] The damping device of the reef sentry building provided by this application has multi-directional energy dissipation, can adjust the friction energy dissipation value according to the amplitude, and improve the natural vibration period of the structure. The damping device of this application is provided with a plurality of linkage rods 4. The linkage rods 4 are equipped with rigid springs. Each linkage rod 4 is respectively connected to different columns 9 of the reef sentry building, and can dissipate the external impact energy received by each column 9. A plurality of sliding friction devices 22 are arranged on the damping device of this application. Each sliding friction device 22 cooperates with the corresponding linkage rod 4 respectively to achieve friction energy dissipation. The sliding friction device 22 is provided with a lifting guide groove 221, which improves the seismic resistance of the building structure. By increasing the number of linkage rods 4, the damping device of this application can be applied to high-rise buildings with a hexagonal structure. The semi-circular friction plate at the end of the linkage rod 4 can slide along the arc-shaped lifting guide groove 221 on the sliding friction device 22. The end of the linkage rod 4 will rise along the slope and simultaneously squeeze the top rubber plate, while the rubber plate provides a greater pressure in return, increasing the friction force of the linkage rod 4, increasing the energy dissipated by sliding friction, and improving the energy dissipation capacity of the damping device, which is beneficial to dealing with different vibration amplitude situations. The damping device of this application installs a rigid spring or other torque energy dissipator 7 that dissipates energy through stretching at the corner of the rotating seat 2. The torque energy dissipator 7 is stretched through the rotational dislocation of the rotating seat 2 and the fixed seat 1 for torsional energy dissipation, and cooperates with the sliding friction device 22 to achieve multi-directional energy dissipation and reduce the torsional vibration period of the building. The damping device of this application installs a pressure alarm in the groove 131 of the elastic sheet 13 (rubber sheet) in the fixed seat 1. When the friction plate at the end of the linkage rod 4 slides a certain displacement in the lifting guide groove 221 of the sliding friction device 22, the pressure of the rubber plate increases, triggering the pressure alarm to send an alarm signal. In this application, a rotational energy dissipator 3 is installed on the rotating seat 2. When the rotating seat 2 is twisted by the linkage rod 4 and undergoes a certain twist, the connecting rod 6 (connecting screw) is triggered to squeeze the rotational energy dissipator 3 to send an alarm, warning in time that the natural vibration period of the building is too large. By changing the installation orientation and quantity of the sliding friction devices 22 in the damping device, this application can adapt to most high-rise sentry posts, and the installation is convenient and fast, ensuring the normal operation of the building structure under the influence of typhoons.
