Problems solved by technology

[0002] Pipeline transportation is widely used in electric power, petroleum and other industries. The liquid in the pipeline has pressure pulsation, which is easy to cause severe vibration of the pipeline. Long-term vibration of the pipeline is likely to cause damage to the pipeline and water ingress. If the oil pipeline is damaged, crude oil will leak and pollute the marine environment.
At present, rigid fasteners such as pipe brackets are used to prevent the pipe from vibrating, but due to the influence of long-term vibration, the bracket is easy to loosen, and the loose bracket will rigidly collide with the pipe, causing damage to the pipe

Embodiment 1

[0027] Such as Figures 1 to 3 As shown, a pipeline damping device includes a housing 2 and a base 11, the housing 2 is a tubular structure, the pipe 1 passes through the middle of the housing 2, and the housing 2 is arranged on the base 11, The inner wall of the housing 2 is provided with several damping mechanisms 5 in the circumferential direction. The damping mechanism 5 includes a cylinder 5b and a piston rod 8. A baffle 5c is arranged inside the cylinder 5b. The baffle 5c The cylinder 5b is divided into a cavity 5c and a buffer chamber 7a, the cavity 5c is provided with an electromagnet 6, the buffer chamber 7a is provided with magnetorheological fluid, and one end of the piston rod 8 is located in the cylinder 5b Inside and the end is fixedly connected with a piston 7, the other end of the piston rod 8 is located outside the cylinder body 5b and the end is fixedly connected with a fixed plate 8a, the piston 7 is provided with several through holes 7b, the piston 7 Slid...

Embodiment 2

[0040] The second embodiment is basically the same as the first embodiment, the difference is that, as Figure 4 As shown, the solar power generation device is replaced by the ocean current power generation device, so that the vibration reduction device can be applied to the underwater environment. The ocean current power generation device includes a generator 12, and the generator 12 is arranged on the semicircular pipe-2a through a bracket 14, so that The end of the input shaft of the generator 12 is provided with an impeller 13, and the ocean current on the seabed drives the impeller 13 to rotate to make the generator 12 generate electricity, which is then stored in the storage battery 4 to provide electric energy to the electromagnet 6 to change the magnetorheological fluid in the buffer chamber 7a. Fluid resistance to realize the damping function of the pipe 1.
