FIG. 2 is an internal schematic view of the nanofluid energy-absorbing structure of FIG. 1;
in the figure: the device comprises a car arrester 1, a foam type car arrester 2, a steel framework 3, a nano fluid energy absorption structure 4, an elastic outer cladding 5 and nano fluid 6.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings, which are provided for purposes of illustration and not limitation.
As shown in fig. 1, a nano energy-absorbing car arrester 1 of the present invention comprises a steel framework 3, a foam type car arrester 2 and a nano fluid energy-absorbing structure 4.
The foam type car stopping fence 2 is formed by attaching polyurethane foam materials to a steel framework 3, and the overall shape of the foam type car stopping fence 2 is composed of a half of a trapezoid and an arc structure. Namely, the material of foam formula rail 2 is polyurethane foam, and foam formula rail 2 is the trapezoidal body, and a side of this trapezoidal body is the arcwall face, and steel framework 3 is pre-buried in foam formula rail 2. The nano-fluid energy absorption structures 4 are arranged in a plurality and are uniformly arranged on the arc-shaped surface of the foam type vehicle stopping rail 2.
The nano fluid energy absorption structure 4 is a trapezoid body, and the lower bottom surface of the trapezoid body is attached to the arc-shaped surface of the foam type car stopping rail 2. As shown in fig. 2, the nanofluid energy-absorbing structure 4 comprises a high-strength elastic outer cladding 5, and the elastic outer cladding 5 is filled with nanofluid 6.
The specific size of the nanofluid energy-absorbing structure 4 can be adjusted according to the actual vehicle type. The elastic outer cover 5 is made of thermoplastic elastomer, and the thermoplastic elastomer includes but is not limited to polyurethane elastomer, polyvinyl chloride or rubber. The nano fluid energy absorption structure 4 can be disassembled, replaced and recycled.
The nano fluid 6 is composed of inorganic non-metal porous material and fluid. The inorganic non-metal porous material is zeolite, silica, active carbon, etc. The fluid is, for example, glycerol or water.
The principle of the utility model is that: the nanofluid 6 can dissipate external kinetic energy on a huge porous material-liquid interface, because under the action of external force, the system can convert external mechanical energy into solid-fluid interface energy and friction heat energy along with the fact that functional fluid enters a micro-nano scale hole above a critical pressure value.
When the speed of the car arrester is out of control during the transportation of the trackless rubber-tired car, a part of kinetic energy is absorbed by the foam car arrester 2, a part of kinetic energy is absorbed by the ground and air, and most of energy is absorbed by the nano-fluid energy-absorbing structure 4. The elastic outer cladding 5 of the nano fluid energy absorption structure 4 deforms under impact, kinetic energy is transferred to the nano fluid 6 inside, and the nano fluid 6 absorbs a large amount of energy, so that safety of passengers is effectively protected.
