Description

Technical Field

[0001] The invention belongs to the technical field of dampers, and in particular to a shock-absorbing damper for high-rise buildings. Background Art

[0002] A shock absorber is a device used to reduce vibration and shock. It works by impeding the relative motion of objects, converting kinetic energy into heat or other dissipative forms of energy, thereby attenuating vibration. Using shock absorbers in high-rise buildings can reduce the building's vibration amplitude under external forces (such as wind and earthquakes), lowering the frequency of structural stresses, thereby protecting the building from damage, extending its service life, and improving the comfort of living and working environments.

[0003] Prior art, such as the patent with publication number CN220167217U, discloses a viscous damper for building shock absorption, which includes a cylinder body, a plug rod slidably connected to the cylinder body, the end of the plug rod extending outside the cylinder body, a connecting seat on both sides of the cylinder body, a groove on the outside of the connecting seat, and openings on both sides of the inner wall of the groove. Two vertical blocks are fixedly connected to the outside of the connecting seat, and the two corresponding vertical blocks are rotatably connected to the sides close to each other, and the two corresponding screws are welded to the ends close to each other. The utility model rotates the knob to drive the rectangular block to move through the screw, and the rectangular block drives the cross seat to move through the connecting plate. The cross seat moves in a direction away from the connecting seat, and the cross seat is fixed in the gap of the structural beam by bolts, so that the height of the viscous damper can be adjusted during installation, so that it can adapt to structural beams with different spacing gaps. It is highly practical and has a beneficial effect on building shock absorption.

[0004] The viscous damper described in the aforementioned patent operates on the principle of fluid motion. Specifically, viscous resistance is generated when a fluid passes through an orifice or undergoes relative motion within a confined space. This resistance converts the kinetic energy generated by the fluid motion into heat, thereby dissipating energy input from external forces such as earthquakes or wind. When a viscous damper undergoes prolonged reciprocating motion in extreme weather conditions (such as typhoons), heat cannot be dissipated promptly, causing the damping oil temperature to rise. This reduces the damping oil's viscosity, resulting in reduced damping force and energy dissipation capacity. Furthermore, seals can age or fail due to the high temperatures, leading to damper oil leakage. Summary of the Invention

[0005] In response to the above problems, the purpose of the present invention is to provide a shock-absorbing damper for high-rise buildings. During the reciprocating motion of the damper body, the sleeve and the inflation piston rod cooperate to pressurize the pressurized box, so that the cooling fluid in the pressurized box flows into the spiral tube, taking away the heat of the damper body. The cooling fluid then flows into the storage box for storage, maintaining the temperature of the damper body within an appropriate range, and avoiding excessive temperature affecting the energy consumption capacity of the damper body.

[0006] The technical solution adopted in the present invention is as follows: A shock-absorbing damper for high-rise buildings includes supports respectively installed and fixed on upper and lower bosses, a damper body hinged between the two supports, a spiral tube fitted with the damper body is provided on the outside of the damper body, one of the supports is connected to a sleeve, and the other support is connected to an air-inflating piston rod slidingly matched with the sleeve, an air outlet one-way valve and an air inlet one-way valve are provided on the sleeve, the air outlet one-way valve is connected to a pressurized tank for placing coolant through a hose, a delivery pipe is provided in the pressurized tank, the delivery pipe is connected to the inlet of the spiral tube through the hose, the outlet of the spiral tube is connected to a return hose, the return hose is connected to a storage box, and a first connecting pipe is provided on the storage box.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] The following combination Figure 1 The present invention is described in detail. Embodiments of the present invention:

[0022] A shock-absorbing damper for high-rise buildings includes supports respectively installed and fixed on upper and lower bosses 1, a damper body hinged between the two supports, a spiral tube 22 fitted with the damper body is provided on the outside of the damper body, one of the supports is connected to a sleeve 17, and the other support is connected to an air-inflating piston rod 8 slidingly matched with the sleeve 17, an air outlet one-way valve 15 and an air inlet one-way valve 16 are provided on the sleeve 17, the air outlet one-way valve 15 is connected to a pressurized tank 10 for placing coolant through a hose, a delivery pipe 9 is provided in the pressurized tank 10, the delivery pipe 9 is connected to the inlet of the spiral tube 22 through the hose, the outlet of the spiral tube 22 is connected to a return hose 21, the return hose 21 is connected to a storage box 20, and a first connecting pipe 19 is provided on the storage box 20.

[0023] The outlet of the hose connected to the air outlet check valve 15 is located at the top of the inner side of the pressurized box 10, and the outlet of the delivery pipe 9 is located at the bottom of the inner side of the pressurized box 10. The outlet height of the spiral tube 22 is higher than the inlet height to ensure that the coolant fills the spiral tube 22 before flowing out of the spiral tube 22, thereby ensuring the cooling effect.

[0024] During the reciprocating horizontal vibration of the high-rise building, the damper body also reciprocates, consuming energy through the damping oil therein; the two supports also produce relative movement, causing the inflation piston rod 8 and the sleeve 17 to move relative to each other. During the opposite movement of the inflation piston rod 8 and the sleeve 17, negative pressure will be generated in the chamber inside the sleeve 17, and the external air will be sucked into the sleeve 17 through the air inlet one-way valve 16. At this time, the air outlet one-way valve 15 remains closed; when the inflation piston rod 8 and the sleeve 17 move toward each other, the air in the sleeve 17 is pressed out of the sleeve 17, and the air enters the pressurized box 10 through the air outlet one-way valve 15 and the hose. The pressurized box 10 is filled with coolant. After the coolant is pressurized, it enters the spiral tube 22 through the delivery pipe 9. In the process of passing through the spiral tube 22, the coolant absorbs the heat on the damper body, so that the heat generated by the damper body is quickly taken away. After absorbing the heat, the coolant enters the storage box 20 for storage through the return hose 21, and the first connecting pipe 19 provided can maintain the internal and external air pressure balance of the storage box 20, making it convenient for the coolant to flow into the storage box 20.

[0025] This application drives the coolant through the horizontal vibration of the building caused by external forces, without the need for electric drive, avoiding the loss of power support in extreme weather and ensuring the normal operation of the shock-absorbing damper in extreme weather.

[0026] The storage tank 20 is located at a higher level than the pressurized tank 10. A drain pipe 18 is located at the bottom of the storage tank 20, connecting to the pressurized tank 10. A second connecting pipe 11 is located at the top of the pressurized tank 10. Both the second connecting pipe 11 and the drain pipe 18 are equipped with valves. Coolant stored in the storage tank 20 flows by gravity through the drain pipe 18 into the pressurized tank 10, enabling coolant recycling. The valves in the second connecting pipe 11 and the drain pipe 18 are normally closed to ensure pressurization within the pressurized tank 10.

[0027] Among them, after the second connecting pipe 11 is opened, the internal and external air pressure of the pressurized box 10 can be kept balanced, which facilitates the flow of coolant into the pressurized box 10; after the second connecting pipe 11 is opened, a pressurizing device can also be used to transport air into the pressurized box 10 to maintain a certain air pressure in the pressurized box 10. After the pressurizing device is pressurized, the valve is closed to ensure that the air transported by the relative movement of the air pumping piston rod 8 and the sleeve 17 can squeeze the coolant in time to move, ensuring that the heat is taken away in time. The above-mentioned valve can adopt a solenoid valve with a manual function (this is the existing technology), that is, a valve that can be manually opened in the absence of electricity. When there is electricity, the coolant can automatically flow into the pressurized box 10 by remotely controlling the opening of the valve. When there is no electricity, the operator needs to go to the site to manually open the valve.

[0028] The sleeve 17 and the pumping piston rod 8 are both hinged to the support, ensuring that the sleeve 17 and the pumping piston rod 8 can deflect and relatively expand and contract during the up and down vibration of the building, thereby avoiding damage to the sleeve 17 and the pumping piston rod 8.

[0029] The spiral tube 22 is a half tube, that is, the coolant is in direct contact with the surface of the damper body, thereby improving the heat absorption efficiency.

[0030] The damper body of the present application is a viscous damper, which includes a cylinder body 23 and a piston rod 24 movably arranged in the cylinder body 23, a spiral tube 22 is arranged on the cylinder body 23, the piston rod 24 is hinged to one of the supports, and the end of the cylinder body 23 away from the piston rod 24 is fixedly connected to the first screw rod 12, and the first screw rod 12 is threadedly connected with a forward and reverse screw nut 14, and the end of the forward and reverse screw nut 14 away from the first screw rod 12 is threadedly connected to a second screw rod 13 hinged to another support.

[0031] The first screw rod 12 and the second screw rod 13 rotate in opposite directions. By rotating the forward and reverse screw nuts 14, the first screw rod 12 and the second screw rod 13 can move relative to each other, thereby adjusting the overall length of the damper body to adapt to different installation situations. For example, the distance between the installation positions reserved for the supports on the two bosses 1 is too long, resulting in the damper body requiring the piston rod 24 to extend a portion of the cylinder body 23 to install the support, and the piston rod 24 extending further out of the cylinder body 23 will cause the stroke of the piston rod 24 to be reduced. The present application can ensure that the piston rod 24 maintains the optimal stroke by adjusting the first screw rod 12 and the second screw rod 13.

[0032] After the forward and reverse thread nuts 14 are adjusted, the first screw rod 12 , the second screw rod 13 and the forward and reverse thread nuts 14 can be connected into a whole by welding to ensure the strength of the connection.

[0033] The support includes a mounting plate 4, through which connecting bolts 3 are movably inserted, connected to the boss 1. A support bracket 6 is vertically mounted on the mounting plate 4 and hingedly connected to the damper body. Threaded sleeves can be pre-embedded in the boss 1 to facilitate the connection of the connecting bolts 3; alternatively, the connecting bolts 3 can be expansion bolts, inserted directly into pre-recorded holes in the boss 1. A connecting rod 7 is vertically mounted on the support bracket 6, to which an inflation piston rod 8 is hingedly connected.

[0034] A support screw 5 is threaded through the mounting plate 4, and the end of the support screw 5 closest to the boss 1 is connected to the abutment plate 2. By adjusting the support screw 5, the hinge points of the two support brackets 6 can be placed on the same horizontal plane, ensuring that the cylinder 23 and piston rod 24 are arranged horizontally, preventing the cylinder 23 and piston rod 24 from tilting and affecting the energy dissipation capacity of the damper body.

[0035] The support plate 2 is rotatably connected to the support screw 5. After the support plate 2 abuts against the boss 1, the support screw 5 can further press against the support plate 2 to prevent the friction between the boss 1 and the support plate 2 from affecting the rotation of the support screw 5, so that the support plate 2 can be further tightly fitted on the boss 1.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
