A first connecting component is installed at one end of the first piston rod, and a copper wire is wound around the other end of the first piston rod. The copper wire is electrically connected to the RGB three-color light. The rear connecting pipe is installed with a permanent magnet. During the movement stroke of the copper wire, the copper wire is in the magnetic field of the permanent magnet. One end of the rear connecting pipe is fixedly connected to the oil cylinder, and a second connecting component is installed at the other end of the rear connecting pipe.

[0008] It should be understood that copper wire is wrapped around the other end of the first piston rod and fixed on the surface of the first piston rod through a process. The copper wire is connected to the RGB tricolor light through a certain length of wire. The length of the wire can meet the requirement that the copper wire is in a relaxed state during the driving process of the second piston rod.

[0011] It should be understood that the groove of the groove sleeve is a stepped thread groove, which includes a large aperture and a small aperture.

[0016] As a preferred implementation, two groups of the limiting sleeves are provided, and the threaded slider is located between the two groups of the limiting sleeves.

[0017] As a preferred implementation, the warning device further includes a buzzer, which is fixed on the rear connecting pipe, and is electrically connected to an RGB three-color light, and the copper wire, the buzzer, and the RGB three-color light are in a loop.

By providing the second connecting assembly, the rotating shaft and the rotating shaft support can change the installation angle of the external component, the groove sleeve and the threaded rod can change the length between the external component and the first connecting assembly, and the threaded rod and the connecting rod can be relatively rotated according to actual installation requirements, and the installation angle of the external component can also be changed;

[0021] 2. By setting up a piston assembly and an early warning device, the first piston rod is controlled to rotate under the action of the slider cooperating with the thread, driving the threaded slider to move in the oil cylinder, changing the oil pressure to meet the demand for increasing or decreasing the movement distance required for the copper wire on the second piston rod to cut the permanent magnet in actual use. The second piston rod drives the piston to move under the resistance of the silicone oil in the oil cylinder. Since the second piston rod drives the copper wire to cut the magnetic field of the permanent magnet, part of the vibration energy can be converted into electrical energy. The current enters the RGB three-color light and the buzzer through the copper wire to transmit and inform the vibration-related danger information. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0031] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0032] Embodiment 1:

[0033] like Figure 1 and Figure 4 As shown, this embodiment provides a new type of viscous damper with an early warning function, a new type of viscous damper with an early warning function, comprising a first connecting component 1, a piston component 2, an early warning device 3 and a second connecting component 4, the first connecting component 1 and the second connecting component 4 are respectively installed at both ends of the piston component 2, the first connecting component 1 is a mounting support, the mounting support is provided with symmetrically distributed through holes, and is used to be installed and connected to a cement wall or a steel structure, the first connecting component 1 and the second connecting component 4 are respectively used to fix the two ends of this example, the piston component 2 is provided with an early warning device 3 at one end close to the second connecting component 4, the movement deformation of the piston component 2 provides working ability for the early warning device 3, and the early warning device 3 alarms the danger information;

[0034] like Figure 1 and Figure 2As shown, the piston assembly 2 includes a first piston rod 21, a second piston rod 22, a seal 23, silicone oil 24, a piston 25, and a cylinder 26. The cylinder 26 has a cylindrical through hole, and both ends of the cylindrical through hole are closed by the seal 23. The first piston rod 21 is fixedly connected to the first connecting assembly 1, and the first piston rod 21 is connected to one end of the second piston rod 22 on which the piston 25 is installed. Seals 23 for sealing the first piston rod 21, the second piston rod 22 and the silicone oil 24 are fixed at both ends of the cylinder 26. Two groups of seals 23 are respectively slidably connected to the first piston rod 21 and the second piston rod 22. There are two seals 23, which are respectively combined with the first piston rod 21 and the second piston rod 22. The first piston rod 21 can rotate or move linearly under the restriction of one seal 23, and the two are similar to the hole-shaft fit. The second piston rod 22 is restricted by another seal 23 and cannot make a rotational motion when making a linear motion (for example, another seal 23 has a slider, and the second piston rod 22 has a slide groove, in Figure 1 Not shown in Figure 1 The sectional plane does not pass through the position of the above-mentioned slide groove and the slider. The slide groove and the slider cooperate with each other. When the first piston rod 21 rotates, it cannot drive the second piston rod 22 to rotate. The seal 23 can also ensure that the silicone oil 24 will not leak out of the cylinder 26 during the movement of the first piston rod 21 and the second piston rod 22. The inner wall gap of the cylinder 26 is matched with a piston 25. The cylinder 26 is a cylindrical inner cavity formed by the sealing member 23. The piston 25 has an axial surface, which can realize the clearance fit in the hole-axis fit. In the case of earthquakes, impacts, etc., this embodiment will generate vibration to move the first piston rod 21. The first piston rod 21 drives the piston 25 to move linearly. The piston 25 moves in the cylinder 26 and is resisted by the silicone oil 24, which will absorb The vibration energy received by the first piston rod 21 is reduced to reduce vibration damage. The second piston rod 22 is fixedly connected to the piston 25. The second piston rod 22 moves linearly with the piston 25. The piston 25 divides the oil cylinder 26 into a first oil chamber and a second oil chamber. A part of the first piston rod 21 is in the first oil chamber, and a part of the second piston rod 22 is in the second oil chamber. The piston 25 is provided with a piston oil hole 251 for the flow of silicone oil 24. According to actual needs, the silicone oil 24 will pass through the piston oil hole 251 to achieve rapid reflux, so that the pressure of the first oil chamber and the second oil chamber returns to balance. The second piston rod 22 has multiple piston oil holes 251 distributed in an annular shape, and a corresponding number of piston oil holes 251 are processed according to actual needs;

[0035] The operation of this embodiment is divided into an initial static state, a shock absorbing motion state, and a restoring motion state according to the motion state of the piston 25. When the first connecting component 1 and the second connecting component 4 of this embodiment are installed to a required position such as a wall or a steel structure, the piston 25 is in an initial static state. When this embodiment is impacted by vibration energy, the first connecting component 1 moves toward the oil cylinder 26, driving the first piston rod 21 to move under the guidance of the seal 23. The first piston rod 21 drives the piston 25 to move in the oil cylinder 26. The silicone oil 24 will hinder and consume the vibration energy carried by the piston 25. This embodiment is in a shock absorbing motion state. At this time, the pressure of the second oil chamber is greater than the pressure of the first oil chamber. When the vibration energy is continuously weakened and is insufficient to continue to drive the piston 25 to move forward, this embodiment will enter a restoring motion state. Since the pressure of the second oil chamber is greater than the pressure of the first oil chamber, the piston 25 will move backward (relative to the forward movement in the shock absorbing state) until the pressure of the second oil chamber is equal to the pressure of the first oil chamber, and the piston 25 returns to the initial static position.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the early warning component 3 includes a permanent magnet 31, an RGB three-color light 32, a copper wire 33, and a rear connecting pipe 34. The first connecting component 1 is installed at one end of the first piston rod 21, and the copper wire 33 is wound around the other end of the first piston rod 21. The copper wire 33 is wound around and fixed on the surface of the first piston rod 21 through a process. For example, the copper wire 33 is wound around the first piston rod 21 after a pre-tightening process, or the first piston rod 21 is threaded and the copper wire 33 is wound around it. Both methods can achieve fixation. The copper wire 33 is electrically connected to the RGB tricolor light 32. The copper wire 33 and the RGB tricolor light 32 are connected by a certain length of wire. The length of the wire can meet the requirement that the copper wire 33 is in a relaxed state during the driving process of the second piston rod 22. The rear connecting pipe 34 is installed with a permanent magnet 31. During the movement stroke of the copper wire 33, the copper wire 33 is in the magnetic field of the permanent magnet 31. One end of the rear connecting pipe 34 is fixedly connected to the cylinder 26. The length of the rear connecting pipe 34 can ensure that the second piston rod 22 will not be hindered in its movement when the piston 25 is in a shock-absorbing motion state and a reciprocating motion state (that is, the second piston rod 22 will not touch the inner wall of one end of the rear connecting pipe 34 where the second connecting component 4 is installed). The other end of the rear connecting pipe 34 is installed with the second connecting component 4. The rear connecting pipe 34 fixes the connecting rod 46 of the second connecting component 4 through processes such as welding and heat treatment.

[0037] When the present example is in the shock absorbing motion state, due to the impact of the vibration energy, the first piston rod 21 drives the piston 25 and the second piston rod 22 to make axial motion, the silicone oil 24 of the oil cylinder 26 consumes the vibration energy, and the copper wire 33 cuts the electromagnetic field generated by the permanent magnet 31 as the second piston rod 22 moves. The copper wire 33 generates a current that is transmitted to the RGB three-color lamp 32 through the circuit. The RGB three-color lamp 32 emits light under the action of the current, and displays different light colors according to the magnitude of the current. The movement speed of the second piston rod 22 is related to the magnitude of the earthquake intensity. The greater the earthquake intensity, the greater its speed. The movement speed of the second piston rod 22 is different. Due to the inconsistency of the current generated by cutting the magnetic field, the greater the speed, the greater the corresponding current. The RGB three-color lamp 32 lights up, indicating that the structure vibrates, achieving the purpose of early warning. The early warning function of the present example is identified by the color of the light. The green light of the RGB three-color lamp 32 indicates that the structure vibrates slightly, representing a small earthquake; the blue light of the RGB three-color lamp 32 lights up, indicating that the structure vibrates more, representing a medium earthquake; the red light of the RGB three-color lamp 32 lights up, indicating that the structure vibrates more, representing a large earthquake.

[0038] like Figure 1 and Figure 7 As shown, the second connecting component 4 includes an external seat 41, a rotating shaft 42, a rotating shaft support 43, a groove sleeve 44, a threaded rod 45 and a connecting rod 46. The external seat 41 is fixed with the rotating shaft 42. The external seat 41 is used to connect to a steel structure or a wall or other location where installation is required. The external seat 41 is processed with a recess for installing the rotating shaft 42. The rotating shaft 42 is placed in and the two are fixedly connected by welding. The rotating shaft 42 is rotatably installed at one end of the rotating shaft support 43. The rotating shaft 42 passes through the mounting hole of the rotating shaft support 43 and is fixed by a bearing or the like (not shown in the figure). The rotating shaft 42 is rotatably connected to the rotating shaft support 43. A groove sleeve 44 is welded at the other end of the rotating shaft support 43. The groove sleeve 44 is threadedly matched with the threaded rod 45. The groove of the groove sleeve 44 It is a stepped thread groove, which includes a large aperture and a small aperture. The threaded portion of the threaded rod 45 in the groove sleeve 44 has a limiting shaft, and the diameter of the limiting shaft is larger than the small aperture of the stepped thread groove. Before the installation of this embodiment, the groove sleeve 44 and the threaded rod 45 are controlled to move relative to each other manually or by a mechanical power-assist tool, and the combined length of the groove sleeve 44 and the threaded rod 45 can be changed to meet the requirements of the installation position or angle. One end of the connecting rod 46 is rotatably connected to the threaded rod 45. Before the installation of this embodiment, the connecting rod 46 and the threaded rod 45 are controlled to rotate relative to each other manually or by a mechanical power-assist tool, so that this embodiment can meet the requirements of the installation position or angle. The other end of the connecting rod 46 is fixedly connected to the rear connecting pipe 34.

[0039] Embodiment 2:

[0040] Based on the first embodiment, the difference from the first embodiment is that, Figure 1 and Figure 2 The piston assembly 2 also includes a threaded slider 27, a slider matching thread 211, a rotating pair 28, and a limiting sleeve 29. The first piston rod 21 and the second piston rod 22 are connected by the rotating pair 28. The structure of the rotating pair 28 is similar to or the same as the structure of the rotating connection of the threaded rod 45 between the connecting rods 46. The first piston rod 21 and the second piston rod 22 can undergo relative movement in the radial plane through the action of the rotating pair 28. The rotating pair 28 includes a cylindrical block, an elliptical block, a bearing, and a cylindrical groove. The cylindrical block and the elliptical block are fixedly connected as a whole. The elliptical block is in the cylindrical groove. The elliptical block cuts out a surface parallel to the plane where the major axis is located, and the cylindrical block is fixedly connected to the surface. The elliptical block forms point contact and line contact with the cylindrical groove except for the surface, and then the bearing is installed on the surface to achieve fixation and ensure rotation ability. The first piston rod 21 is provided with a slider matching thread 211. The slider matching thread 211 and the threaded slider 27 cooperates, the first piston rod 211 rotates, and the slider cooperates with the thread 211 to drive the threaded slider 27 to move in the inner wall of the cylinder 26, which can change the pressure in the cylinder 26, that is, the pressure in the first oil chamber and the second oil chamber changes. When the current of the three color lights of the RGB tricolor lamp 32 required to light up remains unchanged, the distance required for the copper wire 33 to move by the second piston rod 22 will change, and the limit sleeve 29 is fixedly connected to the inner wall of the cylinder 26. The limit sleeve 29 is provided with two groups, and the threaded slider 27 is located between the two groups of limit sleeves 29. Since the length of the slider cooperation thread 211 processed on the first piston rod 21 is limited, the limit sleeve 29 can limit the movement distance of the threaded slider 27 to prevent the threaded slider 27 from detaching from the slider cooperation thread 211, and the first piston rod 21 cannot realize the movement control of the threaded slider 27. One end of the threaded slider 27 is a cylindrical shaft, and the cylinder 26 has a cylindrical through hole, and the threaded slider 27 and the cylinder 26 are clearance-matched.

[0041] Under the condition that the current required to light up the three colors of the RGB tricolor lamp 32 remains unchanged and the vibration energy remains unchanged, when the threaded slider 27 moves in the direction away from the first connecting component 1, the pressure of the silicone oil 24 in the oil cylinder 26 changes, the pressure of the first oil chamber and the second oil chamber increases, the movement speed of the second piston rod 22 will slow down, and the distance required for the second piston rod 22 to drive the copper wire 33 to move increases. When the threaded slider 27 moves in the direction close to the first connecting component 1, the pressure of the silicone oil 24 in the oil cylinder 26 changes, the pressure of the first oil chamber and the second oil chamber decreases, the movement speed of the second piston rod 22 becomes faster, and the distance required for the second piston rod 22 to drive the copper wire 33 to move decreases. By adjusting the threaded slider 27 through the first piston rod 21, the requirements of the structural size design corresponding to the present embodiment can be realized, and the requirements of changing the pressure of the silicone oil 24 at different positions according to the predicted vibration intensity to ensure that the alarm function is easier to realize can also be met in the actual installation environment.

[0042] like Figure 1 and Figure 6As shown, the early warning device 3 also includes a buzzer 35, which is fixed on the rear connecting pipe 34. The buzzer 35 is electrically connected to the RGB three-color light 32. The copper wire 33, the buzzer 35, and the RGB three-color light 32 are in a loop. When the copper wire 33 cuts the permanent magnet 31 to generate current, the current will be transmitted to the buzzer 35 and the RGB three-color light 32, so as to realize sound and light alarm and better remind people of dangerous information.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
