[0002] A viscous damper is a device that relies on speed changes to control energy dissipation, and is usually used in structural engineering to improve the seismic and wind resistance performance of large structures such as buildings and bridges under abnormal load conditions such as earthquakes and wind loads; the main function of the viscous damper is to dissipate energy through the viscous resistance of liquid or gas when the structure is subjected to sudden external forces, thereby reducing the vibration and displacement of the structure and avoiding or reducing the damage of the structure.
[0003] Limited by the on-site environment and the performance of measurement equipment, manual measurement is difficult to ensure high precision. At the same time, manual measurement may not be able to capture the instantaneous displacement of the damper in emergencies in a timely manner and cannot provide accurate real-time monitoring data.

[0036] The present application proposes a monitoring type viscous damper device for monitoring the internal displacement of the damper, thereby measuring displacement data, which can be uploaded to the network to form real-time monitoring data.
[0037] For reference, Figure 1-2, this application mainly consists of three parts: a working shaft 1, a first connecting shaft 2, and a second connecting shaft 3. Among them, the first connecting shaft 2 and the second connecting shaft 3 are connected to external devices during use, while the working shaft 1 realizes the movement and monitoring of the damper through internal activities.
[0038] For reference Figure 1-3 , where the working shaft 1 is arranged in the middle of the first connecting shaft 2 and the second connecting shaft 3. Its main structure includes a housing 11, a piston 12, a first piston rod 13, a second piston rod 14, and a connecting cylinder 15; the piston 12 is arranged inside the housing 11; the first piston rod 13 and the second piston rod 14 are arranged coaxially and penetrate through the housing 11; the connecting cylinder 15 is arranged at one end of the housing 11 where the second piston rod 14 is inserted. Among them, the first piston rod 13 is movably connected to the piston 12, and the second piston rod 14 is fixedly connected to the piston 12; its structure is a common existing damper structure. The inner cavity of the connecting cylinder 15 and the inner cavity of the housing 11 bear the movement of the first piston rod 13 and the second piston rod 14. In order to avoid the shock absorption effect of the first piston rod 13 during movement, a rubber bellows 5 is sleeved on the side of the first piston rod 13 exposed outside the housing 11; its structure is a common and mature existing technology, and the specific operation steps of this application will not be elaborated here.
[0039] For reference Figure 1 , the working shaft 1 further includes a monitoring member 16 in addition to the above. The monitoring member 16 plays an internal monitoring role. The monitoring member 16 includes a central rod 161, two laser displacement sensors 162, and two reflecting plates 163; one end of the central rod 161 is fixedly connected inside the connecting cylinder 15, and the other end is inserted into the groove 4, and its inserted end extends to the middle position of the groove 4; at the same time, due to the setting of the central rod 161, the groove 4 is divided into two spaces;
[0040] The two laser displacement sensors 162 are arranged on both sides of the central rod 161 and fixedly connected to the connecting cylinder 15, and perform displacement monitoring in the direction of the groove 4; among the two laser displacement sensors 162, the detection beams emitted will irradiate in the two spaces divided by the central rod 161 in the groove 4, and the two reflecting plates 163 are asymmetrically arranged on both sides of the central rod 161 and in the two divided spaces. The two reflecting plates 163 are in a straight line correspondence with the two laser displacement sensors 162. When the laser displacement sensors 162 start to work, corresponding to the two reflecting plates 163, since the laser displacement sensors 162 are fixedly connected inside the connecting cylinder 15 and do not move, but the reflecting plates 163 will change their positions relative to the laser displacement sensors 162 due to the movement of the second piston rod 14 and the first piston rod 13, so as to monitor the change of the internal piston rod. In order to realize the timely display of the monitoring data, it can be connected to an external computer system.
[0041] Further, the reason for setting two reflecting plates 163 is to judge the correctness of the monitoring values through two sets of monitoring data, and the two reflecting plates 163 are set at different positions. It is to calculate whether there is side deviation inside according to the initial value. If there is deviation, the value on one side increases and the value on the other side decreases, resulting in a difference from the initial calculation difference index. Thus, not only the displacement monitoring is realized, but also the internal side deviation inspection can be realized, thereby ensuring the installation of the damper.
[0042] Further explanation, the connecting cylinder 15 is in a U shape, divided into a cylinder body 151 and a cylinder cap 152. The cylinder cap 152 is detachably installed at one end of the cylinder body 151 away from the housing 11, thus facilitating the installation and maintenance of the monitoring member 16.
[0043] Both sides of the damper are connected to other equipment structures through the first connecting shaft 2 and the second connecting shaft 3. The first connecting shaft 2 includes a welding sleeve 21, a first earring 22, a first ball shaft 23 and a first pin shaft 24; the welding sleeve 21 is arranged at one end of the first piston rod 13 away from the housing 11; the first earring 22 is arranged at one end of the welding sleeve 21 away from the first piston rod 13; the first ball shaft 23 is arranged on the first earring 22, and the first pin shaft 24 is arranged on the first ball shaft 23 to connect with the external structure. Through the first ball shaft 23, the direction is changed. Its structure is a common technology of existing viscous dampers, and this application will not elaborate too much on this.
[0044] The second connecting shaft 3 is roughly the same as the first connecting shaft 2 in structure. Since there is no need to establish a connection with the damper rod, the structure of the welding sleeve 21 is reduced compared with the first connecting shaft 2. The second connecting shaft 3 includes a second earring 31, a second ball shaft 32 and a second pin shaft 33. The second earring 31 is arranged at one end of the connecting cylinder 15 away from the housing 11, the second ball shaft 32 is arranged on the second earring 31, and the second pin shaft 33 is arranged on the second ball shaft 32; its structure plays the same role as the first connecting shaft 2 in connecting with the external structure.
[0045] In the present utility model, the working steps of the device are as follows:
[0046] 1. First, the laser displacement sensor 162 inside can be connected to the external computer system, and then a communication is established between the computer and the monitoring personnel;
[0047] 2. Secondly, the first piston rod 13 and the second piston rod 14 work inside. When the position changes, the distance between the reflecting plate 163 and the laser displacement sensor 162 is changed;
[0048] 3. Then, the internal situation is monitored according to the distance and the difference between the two reflecting plates 163;
[0049] 4. Finally, the monitored values are transmitted to a computer system for processing, and in the case of objections to the processing results, the monitoring personnel are notified for maintenance.
[0050] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
