[0032] The embodiment of the present application solves the technical problem in the prior art that the working state of the damper cannot be monitored in real time by providing a multifunctional monitoring damper, thereby achieving real-time monitoring of the working state of the damper and ensuring the shock absorbing effect of the damper.

[0035] An embodiment of the present disclosure provides a multifunctional monitoring damper, including: a cylinder assembly 100, in which a first chamber and a second chamber are formed, the first chamber is filled with a damping medium 110, and a first connecting seat 200 is installed at the end of the cylinder assembly 100 close to the second chamber; a piston assembly 300, including a piston rod 310 and a piston 320, one end of the piston rod 310 passes through the first chamber and enters the second chamber, and the other end of the piston rod 310 is installed with a second connecting seat 400, and the piston 320 is slidably installed in the first chamber and connected to the piston rod 310; a monitoring assembly, including a proximity sensor 510 installed on the second connecting seat 400, a pin sensor 520 installed on the first connecting seat 200, a temperature sensor 530 and a pressure sensor 540 connected to the damping medium 110.

[0036] The multifunctional monitoring damper provided in this embodiment is described below in conjunction with the accompanying drawings.

[0037] Figure 1 A schematic structural diagram of a multifunctional monitoring damper provided in one embodiment of the present disclosure. Figure 2 for Figure 1 A cross-sectional view of the multifunctional monitoring damper along the XY plane is shown. Figure 3 A schematic structural diagram of a second sealing component of a multifunctional monitoring damper provided in one embodiment of the present disclosure. Figure 4 A schematic diagram of the structure of a piezoelectric coating of a multifunctional monitoring damper provided in one embodiment of the present disclosure.

[0038] like Figure 1-Figure 2 As shown, the oil cylinder assembly 100 is used to accommodate the damping medium 110. Specifically, the damping medium 110 can be hydraulic oil and methyl silicone oil. The piston rod 310 is arranged in the oil cylinder assembly 100 and moves axially. The piston 320 moves axially in the first chamber driven by the piston rod 310 and squeezes the damping medium 110 in the first chamber. The squeezed damping medium 110 flows through the through hole in the piston 320 to dissipate energy, playing a role in shock absorption and anti-vibration. The first connecting seat 200 and the second connecting seat 400 facilitate the connection of the multifunctional monitoring damper with the required equipment. The required equipment can transmit the tension or pressure to the damper through the first connecting seat 200 and the second connecting seat 400. The proximity sensor 510 is used to be installed on the second connecting seat 400 and opposite to the end face of the cylinder assembly 100. The working displacement of the damper is obtained by measuring the distance between the end face of the cylinder assembly 100; the pin shaft sensor 520 is installed on the first connecting seat 200. The resistance of the damper during operation is determined by collecting the shear force of the pin shaft on the first connecting seat 200. The temperature sensor 530 and the pressure sensor 540 obtain the temperature and pre-pressure in the cylinder by contacting the damping medium 110, thereby obtaining the working state of the damper, providing support for the seismic safety assessment of the building.

[0039] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0040] By setting a temperature sensor 530 and a pressure sensor 540, the temperature and pressure of the damping medium 110 in the damper are monitored in real time; by setting a displacement sensor, the working displacement and moving speed of the damper are monitored, and by setting a pin sensor 520, the shear force of the pin on the first connecting seat 200 is monitored; real-time monitoring of the working state of the damper is achieved, providing support for the earthquake safety of the building and ensuring the effectiveness of shock absorption and earthquake resistance.

[0041] For example, the cylinder assembly 100 includes: a first cylinder body 120 and a second cylinder body 130 that are coaxially arranged, the first chamber is arranged in the first cylinder body 120, and the second chamber is arranged in the second cylinder body 130; a first sealing component 140, which is installed in the first cylinder body 120 and is arranged at the connection between the second chamber and the first chamber; a second sealing component 150, which is installed in the first cylinder body 120 and is arranged at the end of the first cylinder body 120 away from the first cylinder body 120, and the piston rod 310 is penetrated by the first sealing component 140 and the second sealing component 150, and is slidably connected to the first sealing component 140 and the second sealing component 150.

[0042] like Figure 1-Figure 2As shown, the first cylinder body 120 and the second cylinder body 130 are detachably connected. When the first sealing component 140 needs to be installed, the first cylinder body 120 and the second cylinder body 130 can be separated to facilitate the installation of the first sealing component 140. The first sealing component 140 and the second sealing component 150 are both installed on the inner wall of the first cylinder body 120. Specifically, the first sealing component 140 and the second sealing component 150 are threadedly connected to the first cylinder body 120. The piston rod 310 is penetrated by the first sealing component 140 and the second sealing component 150, and is slidably connected to the first sealing component 140 and the second sealing component 150, so as to drive the piston 320 to move axially in the first chamber, so that the damping medium 110 flows through the through hole on the piston 320.

[0043] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0044] The damping medium 110 is sealed in the first chamber by providing the first sealing component 140 and the second sealing component 150 , and is threadedly connected to the first cylinder body 120 to ensure that the piston rod 310 or an external force does not displace, thereby improving the strength of the damper.

[0045] For example, a conduit 151 is provided at one end of the second sealing component 150 close to the damping medium 110 , the pressure sensor 540 is installed in the second sealing component 150 and communicates with the conduit 151 , and the temperature sensor 530 is installed in the second sealing component 150 and abuts against the pressure sensor 540 .

[0046] like Figure 3 As shown, the pressure sensor 540 and the temperature sensor 530 are both installed in the second sealing component 150. When the piston rod 310 is displaced, the damping medium 110 flows in the first chamber and is transferred to the pressure sensor 540 through the conduit 151. A through hole for the damping medium 110 to flow is provided between the temperature sensor 530 and the second sealing component 150, so that the temperature sensor 530 can monitor the temperature of the damping medium 110.

[0047] For example, a float 152 is disposed in the conduit 151 , and the float 152 moves toward the pressure sensor 540 under the action of the damping medium 110 .

[0048] like Figure 3 As shown, the pressure of the damping medium 110 is transmitted to the pressure sensor 540 through the float 152 , thereby preventing the pressure sensor 540 from directly contacting the damping medium 110 for a long time and causing the pressure sensor 540 to malfunction, thereby increasing the service life of the pressure sensor 540 .

[0049] For example, the first connecting seat 200 includes: a pin head ear plate 210, which is threadedly connected to the second cylinder body 130, and a first connecting hole 220 is opened on the pin head ear plate 210; a first pin shaft 230, which is installed in the first connecting hole 220; a piezoelectric coating 240, including a piezoelectric layer 241, a protective layer 242 and a metal layer 243 stacked in sequence, the piezoelectric layer 241 is stacked on one end of the first pin shaft 230, and the ultrasonic probe of the pin shaft sensor 520 is in contact with the metal layer 243.

[0050] like Figure 2-Figure 4 As shown, the first pin 230 is installed in the first connecting hole 220, the piezoelectric coating 240 is stacked on one end of the first pin 230, and the ultrasonic probe of the pin sensor 520 is in contact with the metal layer 243. The external force exerted on the first pin 230 is obtained by testing the propagation speed of the ultrasonic signal, and a displacement-force hysteresis curve is drawn according to the displacement monitored by the displacement sensor, so as to obtain the energy dissipation of the damper, thereby determining the energy dissipation and shock absorption capacity of the damper.

[0051] For example, the second connection base 400 includes:

[0052] The rod end joint bearing 410 is connected to the piston rod 310 , and a second connection hole 420 for connecting the required equipment is opened on the rod end joint bearing 410 . The proximity sensor 510 is installed on the rod end joint bearing 410 to measure the distance between the rod end bearing 410 and the end face of the first cylinder body 120 .

[0053] like Figure 1-Figure 2 As shown, the rod end joint bearing 410 is connected to the section of the piston rod 310, and the second connecting hole 420 is used to connect the required equipment. Specifically, the required equipment can be a second pin shaft, which is used to transmit the tension or pressure to the piston rod 310 to make the piston rod 310 move axially.

[0054] For example, along the axial direction, the piston 320 is provided with at least one set of through holes for the damping medium 110 to flow through, so that the damping medium 110 flows through the through holes to achieve the function of shock absorption and anti-vibration.

[0055] For example, a damping gap is provided between the piston 320 and the first cylinder body 120 for the damping medium 110 to flow through, so that the damping medium 110 flows through the damping gap to achieve the function of shock absorption and shock resistance.

[0056] For example, Figure 1-Figure 2As shown, the apparatus further includes: a processor 600, which is mounted on the oil cylinder assembly 100, and the proximity sensor 510, the pin sensor 520, the temperature sensor 530 and the pressure sensor 540 are all electrically connected to the processor 600. In this embodiment, the processor 600 is used to receive, store and process data from the proximity sensor 510, the pin sensor 520, the temperature sensor 530 and the pressure sensor 540, and send the processed data to the client for the user to view.

[0057] It should be noted that the components among the various embodiments of the present disclosure can be interchangeable as long as they can play the corresponding roles.
