Specific embodiment
It is practical new to this with reference to the accompanying drawing in order to keep the purpose of this utility model, technical solution and advantage clearer
Type specific embodiment is described in further detail.It is understood that specific embodiment described herein is used only for solving
Release the utility model, rather than the restriction to the utility model.
As illustrated in the accompanying drawings from 1 to 3, a kind of sign board waterborne, including rangefinder 1 and light-emitting diode display.Needed for rangefinder 1 is mounted on
The bridge bottom surface of bridge navigational clearance height is measured, such rangefinder 1 can measure installation place to the distance of the water surface, because knowing
The mounting height of road rangefinder 1, it is possible to which the algorithm being previously set draws the real-time navigable head room of bridge；
LED display 2 is fixedly mounted on bridge, to show the navigational clearance height of bridge.LED display 2 and rangefinder 1 connect
Connect, 1 real-time measurement of rangefinder to bridge navigational clearance high transmission to LED display 2 on, LED display 2 and rangefinder 1
Connection type can be to be wirelessly connected and wired connection, wherein being wirelessly connected can connect for bluetooth connection, WIFI connection etc.
Mode, then LED display 2 can go out the navigational clearance height of bridge with real-time display, and boat hand can be directly from LED display 2
On read the real-time navigational clearance height of the bridge, be not in the observation error of traditional pouring ruler measurement.
The rangefinder 1 includes radar level gauge 11, balancing device 12 and shell 13.Radar level gauge 11 is using transmitting-
The operating mode of send-receive.The antenna of radar level gauge 11 launches electromagnetic wave, these electromagnetic waves are anti-through measurand surface
It after penetrating, then is received by the antenna, electromagnetic wave is from the received time is emitted to directly proportional at a distance from liquid level, and relational expression is for example as follows: D
(D: radar level gauge 11 arrives the distance of liquid level to=CT/2；C: the light velocity；T: electromagnetic wave runing time), radar level gauge 11 records arteries and veins
It rushes the time of wave experience, and the transmission speed of electromagnetic wave is constant, then can calculate the distance that liquid level reaches radar antenna, to know
Not the characteristics of liquid level of road liquid level does not need transmission medium, is not influenced by the mist that volatilizees in atmosphere, steam, slot, using contactless survey
Amount, is not influenced by physical characteristics such as the density of tank liquid, concentration.In addition know the height and bridge that radar level gauge 11 is installed
Distance D1 in pier bracket, so actual bridge headroom headway is d=D+D1.The radar level gauge 11 and balance dress
It sets 12 to be installed in inside shell 13, the shell 13 of rangefinder 1 provides a shell so that the installation of radar level gauge 11 is empty
Between, and provide the intermediary an of radar level gauge 11 and the fixed installation of bridge bottom surface.12 upper end of balancing device is fixed
In 13 upper inside of shell, lower end is connected to radar level gauge 11；Radar level gauge 11 is connected by balancing device 12 and shell 13
It connects, 12 upper end of balancing device and 13 junction of shell are flexible material, and radar level gauge 11 passes through balancing device 12 and shell 13
Connection can make its own keep plumbness, so not needing the position for artificially adjusting shell 13 or radar level gauge 11
Come so that radar level gauge 11 is in a vertical state, it is only necessary to shell 13 is fixedly mounted on bridge bottom surface, by
Exist in balancing device 12, radar level gauge 11 can keep plumbness under the action of the gravity of itself again.
Further, the balancing device 12 includes two buffering balls；The principle of buffering ball is: driving under same energy
Its move distance of the bigger object of quality is smaller, and swing is reduced with this principle and has the function that buffering.The buffering ball it
Between be fixedly connected by connecting rope 123；Buffering ball 1 is fixedly connected by connecting rope 123 2 with 13 upper inside of shell；
Buffering ball 2 122 is fixedly connected by connecting rope 123 3 with radar level gauge 11, and when shell 13 shakes, vibration is first by even
Splicing 123 2 is transmitted to buffering ball 1, because the effect of the weight of buffering ball 1 itself and inertia, enables to shell
13 vibrations cause the amplitude of fluctuation of connecting rope 123 2 to reduce, and the swing of buffering ball 1 can absorb most shells 13 and shake
The kinetic energy of coming is moved,；The swing of buffering ball 1 drives the swing of connecting rope 123 1 and the swing of buffering ball 2 122, buffering ball
2 122 itself weight and inertia can make its amplitude of fluctuation reduce so that making connecting rope 123 3 and and connecting rope
The swing of the radar level gauge 11 of 123 3 connections is reduced, and due to the effect of buffering ball 1 and buffering ball 2 122, shell 13 shakes
It moves so that the swing of radar level gauge 11 can almost be ignored.
Further, the shape size weight of described two buffering balls is the same, so that the setting of balancing device is simpler.
Further, the weight of the buffering ball is greater than radar level gauge 11, and buffering ball quality is greater than radar level gauge 11,
So the inertia ratio radar level gauge 11 of buffering ball is big, when the quality of buffering ball is bigger than radar level gauge 11 obtains more,
Buffering ball can absorb the kinetic energy that more shells 13 shake, and reduce the pendulum that the kinetic energy that shell 13 shakes brings radar level gauge 11
It is dynamic.
Further, the buffering ball is shot, and lead is the maximum stable element of quality, energy under the premise of same volume
It enough maximizes the quality of buffering ball, the shell 13 of rangefinder 1 can be done small, saving cost.
Further, the length of connecting rope 123 2 and connecting rope 123 3 is less than connecting rope 123 1, is meeting radar level
Radar level gauge 11 is made to receive the amplitude that vibration is swung under the premise of the installation of meter 11 smaller.
Further, it is equipped with installation through-hole 131 on the upside of the shell 13 of the rangefinder 1, rangefinder 1 passes through installation through-hole
131 are screwed and are mounted on bridge bottom.
Further, the lower side through hole of the shell 13 of the rangefinder 1 be equipped with drainage hole 132 and with measurement through-hole 133, survey
Amount through-hole 133 is so that radar level gauge 11 emits electromagnetic wave by it；Because measurement through-hole 133 there must be, and survey
Distance meter 1 is mounted on bridge bottom surface, and steam ingredient is big, so moisture can be added up by sometimes having in rangefinder 1, it is logical to need to be arranged draining
Hole 132 evaporates the moisture in rangefinder 1 when temperature is high to eject or steam is stacked into droplet and flows out.
Further, foam cotton layer is equipped with outside the shell 13 of the rangefinder 1, foam surface layer 135 is glutinous using adhesive
It is attached to outside shell 13.Shell 13, which is equipped with foam cotton layer, can play the role of a bradyseism, can absorb the vibration of top bridge
Energy and measurement wind energy, reduce opposite radar range finder 1 influence.
Further, active carbon layer 134 is equipped with inside the shell 13 of the rangefinder 1, active carbon layer 134 is honeycomb,
Active carbon layer 134 is pasted inside shell 13 by adhesive, and 134 water absorbing capacity of active carbon layer is high, can be adsorbed outside rangefinder 1
Aqueous vapor in shell 13, so that aqueous vapor causes measurement error without being adhered to influence measurement on radar level gauge 11.
The utility model is not limited to above-mentioned implementation method, if the various changes or deformation to the utility model are not
The spirit and scope of the utility model are detached from, if these changes and deformation belong to the claim and equivalent skill of the utility model
Within the scope of art, then the utility model is also intended to encompass these changes and deformation.
