Detailed Description
In order to better understand the technical solutions of the present application, the damping device provided in the present application is described in detail below with reference to the accompanying drawings.
The damping device of the photovoltaic flexible support is structurally shown in fig. 1 and comprises a connecting piece 2 and at least two damping mechanisms 3. The connecting piece 2 is used for connecting with the cable structure 1, and the cable structure 1 can refer to structures such as steel cables in the prior art. The connecting piece 2 is sleeved on the cable structure 1 of the photovoltaic flexible support and is fixed with the cable structure 1. The cable structure 1 may be provided with a plurality of damping means in the length direction, thereby damping vibrations of the cable structure 1.
The connecting piece 2 is provided with a connecting surface 202, one end of the damping mechanism 3 is connected with the connecting surface 202, and the other end is fixedly arranged. When the cable structure 1 vibrates, the distance between the connecting piece 2 and the fixed end of the damping mechanism 3 is changed continuously, and the length of the damping mechanism 3 is also changed continuously. The damping mechanism 3 can prevent the change of the length thereof, thereby playing a role in restraining the vibration of the cable structure 1. The damping mechanisms 3 are connected with the connecting assembly, and a preset included angle is formed between every two adjacent damping mechanisms 3. When the cable structure 1 vibrates, the damping mechanisms 3 can damp the vibration of the cable structure 1 from different directions. The damping mechanism 3 may refer to any one or combination of a spring damper, a hydraulic damper, a pulse damper, and a viscous damper in the prior art.
In this embodiment, the damping device includes at least two damping mechanisms 3, the damping mechanisms 3 are all connected with the connecting piece 2, and a preset included angle is formed between two adjacent damping mechanisms 3. When the link 2 vibrates with the cable structure 1, the respective damping mechanisms 3 pull the link 2 from different directions, thereby suppressing the vibration of the cable structure 1. In addition, because the vibration inhibiting directions of different damping mechanisms 3 are different, the problem that damping is invalid when the cable structure 1 is perpendicular to one damping mechanism 3 to vibrate is avoided, and the vibration inhibiting effect of the damping device is ensured.
In some embodiments, as shown in fig. 1, the damping mechanism 3 is two, and the connecting member 2 has two connecting surfaces 202. The damping mechanisms 3 are connected with the connecting surfaces 202 in a one-to-one correspondence, and the damping mechanisms 3 are arranged perpendicular to the connecting surfaces 202. The damping mechanism 3 may be fixed to the connecting member 2 by welding, screwing, or the like. Since the two adjacent damping mechanisms 3 have a predetermined angle therebetween, the corresponding two connecting surfaces 202 also have an angle therebetween, and the sum of the angles of the two connecting surfaces 202 and the predetermined angle is 180 degrees. Of course, the number and distribution of the damping mechanisms 3 may be set by the user as required, and the present utility model is not limited thereto.
In some embodiments, the connector 2 is cylindrical. As shown in fig. 2, the connection surface 202 is formed on the side wall of the connection member 2, and the connection surface 202 is parallel to the axis of the connection member 2. The damping mechanism 3 is perpendicular to the connection surface 202, and the axis of the damping mechanism 3 intersects with the cable structure 1. When the cable structure 1 vibrates, the acting force applied by the cable structure 1 to the damping mechanism 3 is distributed along the axial direction of the damping mechanism 3, so that the damping function of the damping mechanism 3 is fully utilized. The two connecting surfaces 202 are distributed along the circumferential direction of the connecting piece 2, and the projections of the two damping mechanisms 3 on the axis of the connecting piece 2 are overlapped, so that the acting forces of the two damping mechanisms 3 can generate resultant force at one point on the axis of the connecting piece 2, and the swinging of the cable structure 1 is reduced.
In some embodiments, as shown in fig. 2, the connector 2 has a connecting hole 201 penetrating along the axis, and the connector 2 is sleeved on the outer circumference of the cable structure 1 through the connecting hole 201. The connecting piece 2 can be positioned with the cable structure 1 by interference fit or pin positioning. In addition, the connecting hole 201 intersects with the axis of each damping mechanism 3, the damping structure is perpendicular to the cable structure 1, and the load formed when the cable structure 1 vibrates acts on the axis of the damping mechanism 3, so that the damping mechanism 3 is compressed, the left-right swing of the damping mechanism 3 is reduced, and the service life of the damping mechanism 3 is prolonged.
In some embodiments, the predetermined included angle is greater than 0 degrees and less than 180 degrees. In the embodiment shown in fig. 2, the included angle between the two connection surfaces 202 is an obtuse angle, and the corresponding preset included angle is an acute angle. Of course, the user can set the preset included angle according to the requirement, which is not limited herein.
In this embodiment, the connection hole 201 of the connection member 2 extends along the axis of the connection member 2, and the connection surface 202 is parallel to the connection hole 201. Meanwhile, the damping mechanism 3 is perpendicular to the connecting surface 202, and the axis of the damping mechanism 3 is intersected with the connecting hole 201, so that load generated when the cable structure 1 vibrates is mainly distributed along the axis of the damping mechanism 3, the damping mechanism 3 can be directly caused to stretch and retract, the swing of the damping mechanism 3 is reduced, the vibration of the cable structure 1 is effectively restrained through the damping mechanism 3, and the service life of the damping mechanism 3 is prolonged.
In some embodiments, the damping mechanism 3 includes a damping insert 320 and two damping covers 310, as shown in fig. 3 to 5, the damping covers 310 have a damping cavity therein, the damping cavity is filled with a damping liquid, and one of the two damping covers 310 is connected to the connection surface 202, and the other damping cover is fixedly arranged. Both ends of the damping built-in 320 are respectively connected with the damping cavities extending into the two damping outer covers 310, and the damping built-in 320 is connected with the side walls of the damping cavities in a sealing manner and is movably connected with the damping outer covers 310. For specific structure, reference is made to syringes and the like in the prior art. Thus, when the damping mechanism 3 is loaded, the damping insert 320 can move in the damping cavity and squeeze the damping liquid in the damping cavity, and the overall length of the damping mechanism 3 is shortened to adapt to the vibration of the cable structure 1. The damping fluid may be a non-newtonian fluid, such as hydraulic oil, etc., and is not limited herein, with reference to the prior art. The damping mechanism 3 may be a spring damper, a pulse damper, or the like in the related art, and is not limited thereto.
In some embodiments, as shown in FIG. 4, damping wrap 310 includes sleeve 311 and sealing connection ring 312. The inside of the sleeve 311 is a damping cavity, and the sealing connection ring 312 is annular and is connected with one end of the sleeve 311 in a sealing manner. The damping built-in 320 penetrates through the inner hole of the sealing connecting ring 312 and stretches into the damping cavity, and the damping built-in 320 moves in the damping cavity along the inner hole of the connecting ring, so that the damping mechanism 3 stretches out and draws back. In the process of shortening the damping mechanism 3, damping liquid in the damping cavity is compressed, the energy of vibration of the cable structure 1 is absorbed, and the vibration of the cable structure 1 is restrained.
In some embodiments, the damper insert 320 includes a connecting rod 321 and two sealing sheets 322. As shown in fig. 5, the sealing pieces 322 have a larger diameter than the connection rod 321, and two sealing pieces 322 are respectively connected to both ends of the connection rod 321, and the connection rod 321 is perpendicular to the sealing pieces 322. The sealing piece 322 can penetrate into the damping cavity and is in fit sealing with the side wall of the damping cavity, and when bearing load, the connecting rod 321 pushes the sealing piece 322 to move in the damping cavity, so that damping liquid is compressed. The sealing connection ring 312 and the sealing piece 322 are matched to realize axial limit, so that the sealing piece 322 is prevented from being separated from the damping cavity. In the installation process, the sealing plate 322 can be firstly arranged in the damping cavity, then the connecting rod 321 is connected with the sealing plate 322, and finally the damping cavity is filled with damping fluid. The specific installation mode can refer to the prior art, and will not be described herein.
In some embodiments, the damping mechanism 3 further comprises an anchor plate that is coupled to the damping housing 310 of the damping mechanism 3 remote from the connector 2. Specifically, an anchor plate is connected to the end of damping housing 310 remote from sealing connection ring 312 for securing damping mechanism 3 to the foundation. One end of the damping mechanism 3, on which the anchor plate is arranged, is fixed on the foundation and keeps still, the other end of the damping mechanism is connected with the connecting piece 2 and vibrates along with the cable structure 1, and the damping mechanism 3 bears and stretches between the foundation and the cable structure 1, so that the energy of vibration is reduced, and the effect of inhibiting the vibration is achieved. Of course, the damping mechanism 3 may be fixed by other structures, or may be fixed to other structures such as a fixing frame, and is not limited thereto.
