Description
Technical field
This utility model relates to a kind of observation device, particularly relates to a kind of simple successive station of the GPS for high accuracy distortion measurement.
Background technology
The most conventional high-precision GNSS (GPS) successive station is usually square column type or cylindrical reinforced concrete pier body.Building course is for excavating the foundation pit of certain size (size of length and project grade, choosing build environment etc. about) under basement rock or soil layer environment, then it is built into square concrete foundation with reinforcing bar, yellow ground, high-mark cement etc., the square of template build given size or circular body observation pier is utilized again on ground, rustless steel forced centering mark is imbedded pier body simultaneously, mark top to flush with observation pier top face, and during observation, GNSS antenna is fixed on observation pier by pedestal and forced centering connecting rod.
Although this observation pier specification standards, easy to use, but construction cost is higher, needs tens thousand of unit interiorly；In addition, owing to construction material and the engineering equipments such as electromotor, concrete mixer such as substantial amounts of water, cement, yellow ground must be transported when building, in ungetable by-place such as Qinghai-Tibet Platean or landform steep hills arteries and veins, the Financial cost built can drastically increase, efficiency of construction is relatively low, and adds potential security risk to construction party；On the other hand, observation pier, from being built into the needs time of more than two weeks of coming into operation, therefore cannot be applicable to urgent observation mission, such as earthquake emergency measurement etc..
Other observation platform, as set up spider, although fast, but it is the most firm, it is easily subject to the factor interference such as high wind, precipitation, domestic animal and wild animal so that observation data are unreliable, so being difficult to competent continuous measurement more than several weeks or several months.
Utility model content
This utility model purpose is the weak point for existing observation technology, it is provided that a kind of simple successive station of the GPS for high accuracy distortion measurement (being called for short simple successive station).
This utility model purpose is achieved in that
It is made up of antenna base, main cylinders, support casing and detachable leg；
Antenna base and main cylinders are vertically connected with；Support casing is inserted in away from the 0.6m of main cylinders bottom；3 legs connect with support casing respectively.
Compared with conventional art, this utility model has the following advantages and effect:
1. the GNSS Continuous Observation platform that a kind of performance is firm is provided；
2., more than the low decades of times of construction cost, two people carry with instrument and can complete, and reduce labor intensity and Financial cost.
Can complete the most within an hour to lay, can come into operation immediately subsequently, be particularly well-suited to task it is pressed for time, such as the emergent deformation monitoring after big shake and landslide monitoring etc..
In a word, this utility model is a kind of to lay the observation platform that the firm GNSS of simple and fast, with low cost, performance measures continuously；It is applicable to the technical fields such as earthquake emergency measurement, crustal movement monitoring, dam and bridge deformation monitoring.

Detailed description of the invention
Describe in detail with embodiment below in conjunction with the accompanying drawings:
One, structure
1, overall
Such as Fig. 1, this utility model is made up of antenna base 10, main cylinders 20, support casing 30 and detachable leg 40；
Antenna base 10 and main cylinders 20 are vertically connected with；Support casing 30 is inserted in away from the 0.6m of main cylinders 20 bottom；3 legs 40 connect with support casing 30 respectively.
Working mechanism:
Basement rock bores a vertical long hole, main cylinders 20 is inserted in deep hole, 3 detachable legs 40 by being threadably mounted on support casing 30, fixing simple successive station, i.e. lay complete；GNSS antenna is arranged on antenna base 10 again, observation can be started, obtain the information such as this area's crustal deformation.
2, functional part
1) antenna base 10
As Fig. 2 .1,2.2, antenna base 10 is a kind of convex block including that the large, medium and small disk that is sequentially connected with from bottom to up is constituted, and roundel is provided with external screw thread.
2) main cylinders 20
Such as Fig. 1, main cylinders 20 is stainless steel tube, long 1.5m, diameter 5cm.
3) support casing 30
Such as Fig. 3, support casing 30 is made up of body 31, hinge 32 and sleeve 33；
An overall structure is connected into by 32 respectively with 3 sleeves 33 of 3 hinges on edge between 3 of body 31；
3 sleeves 33 can only move by free vertical folding.
(1) body 31
Body 31 be a kind of outside be regular hexagon, inner side be piece of stainless steel circular for 5cm, tightly overlap and be fixed in main cylinders 20.
