Abstract
The utility model relates to a sliding split radar antenna fixing device with changed spacing, which comprises two radar connecting rods which are arranged in parallel, and two fixing rods which are arranged in parallel are connected between the two radar connecting rods through clamping and anti-dropping slots. In the sliding split radar antenna fixing device, the fixing rods can be disassembled at ordinary times, and is split into the two fixing rods and two radar equipment. When the fixing rods are used, the fixing rods and the radar connecting rods are connected through the clamping and anti-dropping slots, and the fastening strength can be adjusted through a fixed bolt. When the spacing of the two radars is needed to be adjusted, the strength of a fastening bolt can be adjusted to be low, then the spacing of the radars can be adjusted, and finally, the fastening bolt is fixed again. When the device is used, the radar connecting rods are tightly held by two persons at two sides, so that the radars can be arranged at one side of an exploration wall surface, the arms of the two persons maintain to be in a parallel state to move front and back, and the look-ahead geological forecast of the radars can be carried out. The sliding split radar antenna fixing device with changed spacing has the advantages that the structure is simple, the carrying is convenient, the spacing is changed, and the like.
Description
Technical field
The utility model relates to a kind of radar antenna fixture, and especially a kind of slip becomes the split type radar antenna fixture of spacing.
Background technology
In China's water conservancy and hydropower, the field of traffic a large amount of Tunnel Engineering are arranged at present, the Tunnel Engineering geological disaster is the key factor of restriction constructing tunnel, because the tunnel front geological condition is not clear, unforeseen geological disaster often appears often, as gushing water, prominent mud, cave in, rock burst and pernicious gas etc.In a single day disaster takes place, and the facility that gently then destroy by rush of water flood the tunnel, and normal construction is forced to interrupt; Heavy then cause great casualties, produce enormous economic loss, even therefore some underground works can be forced to suspend or relocate.Radar equipment can carry out constructing tunnel unfavorable geology advanced prediction.Before building hydroelectric project, at first to carry out engineering geological investigation.The common means that adopt of engineering geological investigation are probings, and its advantage is directly simple, and shortcoming is higher to the space requirement in place, and expense is bigger, and is " a peephole view ", and the geological condition between the hole only depends on supposition, can't determine.
Compare with drilling method, the geological radar technology has bigger advantage. because it is the prospecting of area form, can obtain underground complete area data, and not high to the place space requirement, expense is lower.If itself and drilling method are combined, replenish checking mutually, then effect is better.Geological radar claims ground penetrating radar, radar (Ground Penetrating Radar is abbreviated as CPR) thoroughly again.The geological radar technology be a kind of high accuracy, continuously harmless, economical fast, image detection means intuitively, be spectrum (1MHz-IGHz) the electromagnetic wave technology that is used for descending definitely dielectric distribution.According to formation method, the geological radar technology can be divided into two kinds of transmission imaging and catoptric imagings.The former is mainly used in and strides the hole detection, it is a kind of CT (tomography) technology, the latter utilizes geological radar transmission antennas transmit high-frequency impulse electromagnetic wave, when electromagnetic wave runs into the different medium that dielectric constant and conductance there are differences in the underground propagation process, to reflect on its interface, the electromagnetic wave that returns the face of land is received antenna and receives.The data such as (also claiming two way travel time, when walking), amplitude and waveform that will receive electromagnetic hourage are handled through numerical value, and show in the mode of X-Y scheme, i.e. the structure of deducibility medium inside.Antenna in the radar equipment device is the key factor that influences the leading precision of this technology, when using radar equipment, need two radar antenna keeping parallelism states, but when using radar at present all be determine whether by range estimation parallel, it is very big influenced by human factor, and inaccuracy often.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, be easy to carry, the slip of variable spacing becomes the split type radar antenna fixture of spacing.
For achieving the above object, the utility model adopts following technical proposals:
A kind of slip becomes the split type radar antenna fixture of spacing, comprises two radar connecting rods that be arranged in parallel, is connected with two fixed levers that be arranged in parallel by the inlay card dislocation preventing slot between the two radar connecting rods.
Be respectively equipped with a longitudinal hole and a cross through hole on the described inlay card dislocation preventing slot, inlay card dislocation preventing slot side is provided with and the vertical separately fastening bolt that communicates of longitudinal hole and cross through hole.
Fixed lever of the present utility model can unload at ordinary times, and split is two fixed levers and two radar equipments, during use, by the inlay card dislocation preventing slot fixed lever is connected with the radar connecting rod, regulates fastening strength by set bolt then.When needing to adjust two radar spacings, fastening bolt intensity can be turned down, adjust the radar spacing then, fixedly fastening bolt gets final product once more.When using this device, need two people's branch both sides to hold the radar connecting rod, make radar place exploration metope one side, two human arm keeping parallelism states, the advance geologic prediction of radar is carried out in moving before and after carrying out.The utlity model has simple in structure, be easy to carry, advantage such as variable spacing.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1,2, a kind of slip becomes the split type radar antenna fixture of spacing, comprise two radar connecting rods 1 that be arranged in parallel, radar connecting rod 1 bottom is provided with between radar antenna 7, the two radar connecting rods 1 and is connected with two fixed levers that be arranged in parallel 3 by inlay card dislocation preventing slot 2.
Be respectively equipped with a longitudinal hole 4 and a cross through hole 5 on the inlay card dislocation preventing slot 2, inlay card dislocation preventing slot 2 sides are provided with and vertical separately two fastening bolts 6 that communicate of longitudinal hole 4 and cross through hole 5.
Fixed lever 3 of the present utility model can unload at ordinary times, and split is two fixed levers 3 and two radar equipments, during use, by inlay card dislocation preventing slot 2 fixed lever 3 is connected with radar connecting rod 1, regulates fastening strength by set bolt 6 then.When needing to adjust two radars, 8 spacings, fastening bolt 6 intensity can be turned down, adjust radar 8 spacings then, fixedly fastening bolt 6 gets final product once more.When using this device, need two people's branch both sides to hold radar connecting rod 1, make radar 8 place exploration metope one side, two human arm keeping parallelism states, the advance geologic prediction of radar 8 is carried out in moving before and after carrying out.
