Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-2, a power cable routing device with excellent plasticity comprises two locking rings 2, the two locking rings 2 are connected through an insulating protective sleeve 1, an electric wire 3 is inserted into each locking ring 2, a groove is arranged on the inner wall of each locking ring 2, a clamping block 6 is slidably connected in the groove, a threaded rod 4 is rotatably connected to the top of the clamping block 6, the threaded rod 4 penetrates through the locking rings 2, a bearing 7 is arranged at the bottom end of the threaded rod 4, the bottom end of the threaded rod 4 is fixedly connected with the inner wall of the bearing 7, the outer wall of the bearing 7 is fixedly connected with the top end of the clamping block 6, the bearing 7 can enable the threaded rod 4 to rotate in the clamping block 6 more stably, anti-skid lines are arranged at the bottom end of the clamping block 6, the anti-skid lines can enable the routing device to better fixedly clamp the electric wire 3, a nut 5 is arranged on the, the outside of the insulating protective sleeve 1 is an insulating rubber sleeve 11, the hollow structure is filled with magnetorheological fluid 12, and the magnetorheological fluid 12 consists of carrier liquid, magnetizable dispersed suspension phase particles and a dispersing agentThe carrier liquid consists of mineral oil, and the magnetizable particles of the dispersed suspension phase consist of elementary Fe and Fe with determined particle size distribution3O4The powder consists of powder, the dispersing agent consists of a surfactant and a thixotropic agent, the surfactant and the thixotropic agent belong to the prior art, and the specific components are not described again.
The working principle of the magnetorheological fluid is that when the magnetorheological fluid 12 does not have the action of a magnetic field, suspended phase particles are suspended in the mother solution and are randomly distributed, and the suspended phase particles are expressed as linear viscous Newtonian fluid. After the external magnetic field is applied, the surface of the particles is polarized to form magnetic dipoles, and the magnetic dipoles are connected into a chain-shaped or cluster-shaped structure along the direction of the external magnetic field and have a certain shear-resistant yield stress. The shear yield stress between adjacent particles in the same polarizing chain increases with the strength of the applied magnetic field. When the magnetic field is increased to a certain degree, the interaction of the magnetic dipoles is enhanced, and the magnetorheological fluid has a solid-like characteristic, namely, the magnetorheological fluid has a low-viscosity Newtonian fluid characteristic under the condition of zero magnetic field; and under the action of a strong magnetic field, the solid material has the characteristics of high viscosity and low fluidity. When the electric wire 3 is inserted into the wire routing device, the electric wire 3 is fixedly locked by rotating the nut 5 on the screw rod 4, then the electric wire 2 sleeved with the wire routing device is placed on a corresponding use occasion, after the electric wire 3 is electrified, according to the magnetic effect of current, if a straight metal wire passes through the current, a circular magnetic field is generated in the space around the wire, the larger the current flowing in the wire is, the stronger the generated magnetic field is, and the magnetic field is circular and surrounds the periphery of the wire. Under the effect of magnetic field, magnetorheological fluid 12 in insulating rubber sleeve 11 can solidify in the twinkling of an eye to form the line device of corresponding shape, when needs change different use occasions, only need the outage, magnetorheological fluid 12 just can the liquefaction, will walk the line device and place wherein together with electric wire 3 again can, convenience simple to use, favourable high-efficient construction.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
