Description
Technical Field
The invention belongs to the technical field of centrifuges, and particularly relates to a pipeline laying structure applied to a high-speed geotechnical centrifuge.
Background
The geotechnical centrifuge is an experimental device applied to the fields of geotechnical engineering and the like, and can simulate an ultra-gravity field by utilizing a stable centrifugal acceleration field formed by high-speed rotation. According to the similarity ratio principle of the model, researchers can carry out experimental study on real-world hundred-meter high dams, giant landslide bodies and the like on a geotechnical centrifuge, evaluate the safety of the real-world hundred-meter high dams, giant landslide bodies and the like, master the occurrence mechanism of landslide and the like. In addition, the geotechnical centrifuge is also widely applied to the fields of deep sea engineering, underground environment pollutant evaluation, earthquake resistance evaluation of urban building structures, high-energy explosion research and the like, and provides strong support for the important strategic fields of disaster prevention and reduction, energy development, environmental protection and the like of large projects.
The high-speed and high-capacity geotechnical centrifuge (shown as gt, g is gravity acceleration, t is mass unit ton) plays an important role in researching geological evolution, migration of environmental pollutants and the like, and the typical structure and the composition of the geotechnical centrifuge are shown in figure 1, wherein a pipeline 1, a pipe clamp 2, a rotating shaft 3, a support 4, a rotating arm 5 and a hanging basket 6 are shown.
To meet the needs of the experiment, it is required that the geotechnical centrifuge has the ability to supply water, electricity, compressed air to the model in the basket. The existing geotechnical centrifuge adopts a metal pipeline when supplying water and air to the hanging basket, and the power supply adopts a cable. The pipe and cable extend from the preformed hole in the shaft and need to extend all the way along the swivel arm to the basket. The geotechnical centrifuge can generate a large centrifugal force (more than 100 times of its own weight, related to g value of the geotechnical centrifuge) on an object mounted on the geotechnical centrifuge during operation. Therefore, in order to prevent the pipeline and the cable from breaking under the action of centrifugal force, protection measures need to be taken, and the existing methods are as follows: the pipeline is fixed by adopting a pipe clamp, and the cable is fixed by utilizing a wire pressing clamp. The pipe clamp and the wire pressing clamp are connected to the rotating arm through screws.
The fixing method for the cable and the pipeline has the following defects:
1. increasing the windage of centrifuges
After the geotechnical centrifuge reaches the rotation speed required by the experiment, most of the power generated by the driving unit is used for overcoming the wind resistance in the operation, and the consumed energy is mainly converted into heat generated by friction between the rotating arm of the geotechnical centrifuge and the air. In a relatively closed machine room, if the heat can not be removed in time, the temperature rise in the machine room is aggravated, the accuracy of an experiment result is affected, and even the safe operation of the centrifugal machine is endangered. Therefore, the good aerodynamic shape is utilized to reduce wind resistance, reduce heat generated by friction and reduce energy consumption.
The rotating arms of the existing geotechnical centrifuges are all machined parts, and the surface smoothness of the rotating arms can be effectively controlled. However, the arrangement of the existing pipes and cables makes it protrude above the upper surface of the rotor arm, destroying the good aerodynamic profile of the rotor arm and increasing the windage of the centrifuge operation.
2. Weak protective ability
To ensure that the pipe and the cable are firmly fixed on the geotechnical centrifuge, the friction force between the pipe clamp and the pipe and between the cable and the wire clamp is respectively larger than the centrifugal force of the pipe clamp and the cable and the wire clamp under the centrifugal field. While the amount of friction between the pipe clamp and the cable is dependent only on the compression force in the case where the pipe clamp and the crimp clamp are made of a material. Because the contact area between the pipe clamp and the pipeline and between the wire pressing clamp and the cable is smaller, the pretightening force of the screw needs to be strictly controlled. Therefore, the situation that the inner battery core of the cable is clamped and broken by the pressing line often occurs during installation.
Secondly, because the outside parcel of cable has elastic material such as rubber, the cable between the messenger can take place to make a round trip under centrifugal force and windage effect for the cable can take place the fracture of inside electric core (especially serious to the thinner signal cable of electric core) after using a period.
In addition, when the centrifuge acceleration reaches 1000g, the conventional pipeline installation structure cannot provide enough friction force to balance the centrifugal force born by the pipeline, otherwise, the applied compression force is too large to cause cable breakage and pipeline breakage.
3. Influencing structural strength of the rotating arm
To install the pipe clamp and the wire clamp for fixing the pipe and the cable on the rotating arm, screw holes are reserved on the rotating arm. With the increase of the rotation speed of the geotechnical centrifuge, in order to ensure the safety of pipelines and cables, the number of pipe clamps and line pressing clamps in a unit length is required to be increased.
However, for high-speed geotechnical centrifuges, the boom stress is drastically worsened at 1000g centrifugal acceleration, and its internal maximum stress is already close to the allowable stress of the material. The screw hole of the installation pipeline is processed on the rotating arm, so that the stress value of the opening position is greatly increased and exceeds the allowable stress of the material, the rotating arm is extremely easy to generate structural damage at the screw hole under a high centrifugal field, and the safe operation of the high-speed geotechnical centrifuge is seriously influenced.
In order to solve the problems, the pipeline laying structure applied to the high-speed geotechnical centrifuge is developed.
