Technical field
The utility model relates to the deformation monitoring sensor, is the reverberator manufacturing field that is fixed on the monitored thing, is used for reflection electromagnetic wave specifically.
Background technology
To buildings, the sedimentation of structures etc., (the deformation monitoring here refers to: country rock deformation monitoring in the tunnel excavation process in the deformation monitoring, country rock deformation monitoring in the excavation of subway process, deformation monitoring during subway uses, subway is the buildings deformation monitoring on the way, subway ground settlement monitoring on the way, the dam safety deformation monitoring, the landslide deformation monitoring, the industry deformation monitoring, building (bridge, skyscraper, television tower, launching tower etc.) sedimentation, deformation monitoring), utilize the electromagnetic distance measurement technology, (it is by being fixed on the main body on the monitored thing and forming with the reflecting plate that main body connects firmly mutually with reverberator, topped on the reflecting plate have a reflection diaphragm, reflection diaphragm is made up of a large amount of miniature triangle crystal) be fixed on the monitored thing, re-use generating laser (as, Switzerland's come card electromagnetic distance measurement total powerstation, Japan opens up general health electromagnetic distance measuring instrument, the Japanese Nikon electromagnetic distance measuring instrument, Zeiss, Germany electromagnetic distance measurement total powerstation, U.S.'s Tian Bao electromagnetic distance measurement total powerstation, and the laser tunnel clearance detecting instrument of homemade Beijing Opto-electrical Technology Research Institute production, bridge degree of disturbing detecting instrument etc.) launching electromagnetic wave, this electromagnetic wave after reflection, be received, handle, obtain the related data of monitored thing deformation.Main body and reflecting plate weld together in the existing reverberator, during use, again main body are welded on the monitored thing.It has firmly, locatees the advantage of the anti-external interference in back.But because aspect installation, the setting accuracy of reverberator requires high, main body can't be done any adjustment to position, the direction of reflecting plate after in a single day fixing with monitored thing welding again, and work brings big difficulty to installing and locating for this; Secondly, reverberator in use owing to the change of external factor, also needs do trickle adjustment to reflecting plate direction, position (referring to height).And existing fixed reverberator can't satisfy above-mentioned requirements; Moreover, be the welding fixed installation owing to have reverberator now, the inconvenience dismounting often after the use once, is promptly accused discarded.
The utility model content
This novel purpose is to provide a kind of deformation monitoring reverberator at the deficiencies in the prior art part, and the orientation of the relative main body of its reflecting plate (being rotational angle) has adjustability.This purpose is realized by following design: a kind of deformation monitoring reverberator, comprise the main body that is used for fixing on monitored thing, the topped indicator board that reflection diaphragm is arranged on it, it is characterized in that, be provided with a cross section in the described main body and be circular inner chamber, main body top is a tubular body, offers an annular slot on this tubular body; Also comprise being used for the centring ring of snare, have the screw that uses lock screw stop on the centring ring at body front part tubular body, the two formation running fit; Described indicator board lower end is fixedly connected with one and stretches the axle that enters main body inner chamber, the two formation running fit; Be provided with the plug-in link gear between described indicator board and the centring ring.By above-mentioned design as seen, main body and reflecting plate (topped reflection diaphragm on it) are designed to two parts, the two forms running fit, centring ring is by forming synchronous rotary state between plug-in link gear and the reflecting plate, use the locking pinning just being rotatably assorted between centring ring and the main body can be changed into lock mode, that is to say and use the locking screw just reflecting plate can be fixed with respect to the orientation of main body, even reflecting plate is fixed in a certain particular rotation angle.Thereby convenient, location, location accurately and is located adjustablely during this novel installation, promptly is in the use of reverberator, also can adjust the rotation direction of reflecting plate easily, adapts to the reflection of electromagnetic wave signal and receives requirement.
Description of drawings
Fig. 1 Fig. 2 is respectively the assembling stereogram of the different visual angles of this novel embodiment;
Fig. 3 is shown in Figure 1 novel wiring layout (centring ring revolves and turn 90 degrees).
Embodiment
Fig. 1 Fig. 2 illustrates, and topped on the indicator board 1 have a reflection diaphragm 2, and it is made up of a large amount of minicrystals, and electromagnetic wave is had extremely strong reflection potential.Indicator board lower end (so-called upper and lower, all for the direction of name parts among Fig. 3, down together) is fixedly connected with one 3, and the neck of contraction 3a is arranged on the axle 3; Be provided with a cross section in the main body 4 and be circular inner chamber, main body 4 is preferably its top of a cylinder (also can be other shape, as rectangular parallelepiped etc.) a circular bead surface 4c; Main body 4 tops are a tubular body, offer an annular slot 4a on this tubular body, and the annular slot section is a triangle.The axle 3 of indicator board 1 stretches and enters the main body inner chamber, forms running fit with it, is preferably the close running fit seat; Have screw 5c on the centring ring 5, the centring ring snare is in (on the circular bead surface 4c position of main body) on the body front part tubular body, and the two forms running fit.The plug-in interlock that is provided with between indicator board 1 and the centring ring 5 (so-called interlock promptly is synchronized with the movement as a member) mechanism is: be fixedly connected with two register pin 5a, 5b on centring ring 5 upper surfaces, offer two blind hole 1a, 1b on indicator board 1 lower surface, register pin 5a, 5b respectively with blind hole 1a, 1b clamping mutually, make centring ring 5 and indicator board 1 form a member.Above-mentioned plug-in link gear also has other multiple mode, as, with the location swap of register pin and blind hole, or open a notch and the clamping etc. mutually of reflecting plate lower end bead on the centring ring.Referring to Fig. 3, main body 4 inner chambers are provided with steel bomb sheet 8, and steel bomb sheet 8 is fixed on main body 4 inner chambers through locating shaft by screw 7, and it blocks pressure mutually with contraction neck 3a on 13 of the indicator board, it makes when the axle of reflecting plate is each to insert the main body inner chamber can both reach same position, and strict fixedly indicator board.Main body 4 lower surfaces are provided with screw 4b, so that install and fix on monitored thing.
