Description
Technical field
The present invention relates to collision prevention girders field, more particularly, to a kind of non-newtonian fluid collision prevention girders.
Background technology
When carrying out road closed, the metal collision prevention girders of strip are using quite varied, the work(on anticollision and closing road surface
Can be also very practical.But more than ten meters of general road is very normal, this is resulted in, and collision prevention girders are huge to be necessarily large and bulky, it is necessary to examines special vehicle
Live handling, the old-fashioned general shell of collision prevention girders are metal, and inside is concrete, and depending on width of roadway, not etc. weight does not reach several tons to more than ten
Ton, handling process need crane etc. to participate in.
The content of the invention
The object of the present invention is to provide a kind of non-newtonian fluid collision prevention girders, are retaining the function used of virgin metal collision prevention girders
In the case of, greatly reduce the work of onsite moving, it is only necessary to which manpower can complete site layout project；
To achieve these goals, the present invention provides a kind of non-newtonian fluid collision prevention girders, including metal shell, the metal
The inside of shell is filled with non-newtonian fluid, and metal shell is equipped with fluid inlet and exhausting-gas hole, and the exhausting-gas hole is arranged on gold
Belong to the upper surface of shell.
Above-mentioned collision prevention girders further include two fluid outlets arranged on metal shell side.
The shape of above-mentioned metal shell is cuboid.
An ellipsoid cavity is equipped with above-mentioned metal shell, the ellipsoid cavity is used to store non-newtonian fluid,
Ellipsoid cavity connects exhausting-gas hole, fluid inlet and fluid outlet by pipeline.
Above-mentioned metal shell upper surface is additionally provided with an air pump, and air pump is connected with ellipsoid cavity by pipeline.
The application method of the non-newtonian fluid collision prevention girders comprises the following steps：
Step 1：Designated position is arranged in for empty metal shell by internal, then modulates non-newtonian fluid；
Step 2：Exhausting-gas hole is opened, then non-newtonian fluid is imported to the ellipsoid cavity of metal shell from fluid inlet
It is interior；
After collision prevention girders use, exhausting-gas hole and air pump, booster air pump are connected, then opens any fluid outlet discharge metal
Non-newtonian fluid in shell, after non-newtonian fluid is drained, closes air pump, exhausting-gas hole, fluid inlet and fluid outlet, then
Metal shell is removed.During non-newtonian fluid is discharged, air pump is closed at regular intervals, then adds water from fluid inlet
Dilute non-newtonian fluid.
Beneficial effects of the present invention：
Collision prevention girders of the present invention greatly reduce scene in the case where retaining the function used of virgin metal collision prevention girders
The work of carrying, it is only necessary to which manpower can complete site layout project；Non-newtonian fluid has viscosity moment enhancing phenomenon, works as automobile
During the collision prevention girders that clash, the non-newtonian liquid in beam can show the hard characteristic such as steel under moment huge power shock, so that
Maintain the crashworthiness of non-newtonian fluid collision prevention girders.Non-newtonian fluid collision prevention girders use finishes, and it is any enterprising to carry front opening
Mouth is opened any lower outlet and is excluded non-newtonian fluid with air filling and pressure balancing.If it is desired to recycling fluid, can connect appearance in lower exit
Device.If discharge is not smooth, it can be diluted with water from upper inlet and be inflated using air blower.After whole is drained, one can pass through hydraulic pressure
Trolley removes non-newtonian fluid collision prevention girders.
Brief description of the drawings
Fig. 1 shows the structure diagram of the present invention.
Embodiment
The preferred embodiment of the present invention is more fully described below with reference to accompanying drawings.Although the present invention is shown in attached drawing
Preferred embodiment, however, it is to be appreciated that may be realized in various forms the present invention without the embodiment party that should be illustrated here
Formula is limited.
As shown in Figure 1, the present invention provides a kind of non-newtonian fluid collision prevention girders, including metal shell 1, the metal shell 1
Inside be filled with non-newtonian fluid, metal shell 1 is equipped with fluid inlet 3 and exhausting-gas hole 2, and the exhausting-gas hole 2 is arranged on gold
Belong to the upper surface of shell 1.
Above-mentioned collision prevention girders further include two fluid outlets 4 arranged on 1 side of metal shell.
The shape of above-mentioned metal shell 1 is cuboid.
An ellipsoid cavity is equipped with above-mentioned metal shell 1, the ellipsoid cavity is used to store non-newtonian fluid,
Ellipsoid cavity connects exhausting-gas hole 2, fluid inlet 3 and fluid outlet 4 by pipeline.
Above-mentioned 1 upper surface of metal shell is additionally provided with an air pump 5, and air pump 5 is connected by pipeline with ellipsoid cavity.
The application method of the non-newtonian fluid collision prevention girders comprises the following steps：
Step 1：Designated position is arranged in for empty metal shell 1 by internal, then modulates non-newtonian fluid；
Step 2：Exhausting-gas hole 2 is opened, then non-newtonian fluid is imported to the ellipsoid cavity of metal shell 1 from fluid inlet 3
In vivo；
After collision prevention girders use, exhausting-gas hole 2 and air pump 5, booster air pump 5 are connected, any fluid outlet 4 is then opened and discharges
Non-newtonian fluid in metal shell 1, after non-newtonian fluid is drained, closes air pump 5, exhausting-gas hole 2, fluid inlet 3 and fluid
