Abstract
The utility model relates to an automatic compensator for horizontally mounting a level-meter, which is provided with a machine frame, a swing body, a damper, a retainer, a fixed mirror which is fixed on the machine frame and is composed of big rectangular prisms, a fixed mirror which is fixed on the machine frame and is composed of orthorhombic prisms, and a movable mirror which is fixed on the swing body and is composed of two small rectangular prisms which are connected by an optical plate. The utility model has the advantages that the utility model adopts an optical structural form that two fixed mirrors and one movable mirror are utilized to form a two-fixing and one-moving type compensator, so a roof prism which has expensive cost and is difficult to install and adjust is eliminated, and the double requirements of coaxality and positive image of the level-meter are realized simultaneously.
Description
The utility model belongs to the parts of optical gauge, particularly a kind of compensator of automatic compensated level.
Automatic compensated level realizes that the core component of self leveling is a compensator, and all compensators that automatic compensated level adopted coaxial, erect image all are the certain dynamic formula compensators that is made of index glass of a horizontal glass both at home and abroad at present.Horizontal glass wherein or index glass just will adopt various forms of roof prisms inevitably, otherwise just can not realize coaxial simultaneously and double requirements erect image.And the roof prism processing difficulties involves great expense, and resetting difficulty is big.
The purpose of this utility model provides a kind of compensator of automatic compensated level, overcomes above-mentioned shortcoming and defect, replaces roof prism, and reaches and realize coaxial simultaneously and dual light path requirement erect image.
The purpose of this utility model is achieved in that
A kind of compensator organic frame of automatic compensated level, pendulum mass, damper, stop, it is characterized in that: be fixed on the horizontal glass () of the big right-angle prism composition on the frame in addition and be fixed on the horizontal glass (two) that the rhombic prism on the frame is formed, be fixed on the index glass that is connected to form with optical flat by two little right-angle prisms on the pendulum mass, horizontal glass () is positioned at the index glass top, and horizontal glass (two) is positioned at the index glass side.
The inclined-plane of two little right-angle prisms in the index glass is vertical mutually, their one of them right angle faces are parallel to each other, their another right angle face sticks on the optical flat, horizontal glass (one) is above the optical flat of index glass, and the inclined-plane of horizontal glass () is parallel with the optical flat of index glass, horizontal glass (two) is positioned at the side of right angle face of a little right-angle prism of index glass, and a plane of horizontal glass (two) is parallel with this right angle face of this little right-angle prism, and vertical with the optical flat of index glass.
Two fixed index prism combinations of an index glass of two horizontal glass have six 45 ° of total reflection inclined-planes that satisfy the Brewster condition.
The compensator frame can be whole, also can be split.
The utility model has the advantages that: adopted two horizontal glass, this optical texture form of index glass has constituted two fixed dynamic formula compensators, both excluded and involve great expense, the roof prism that is difficult to debug has been realized the double requirements of the coaxial and erect image of automatic compensated level again simultaneously.

The structure of the compensator of automatic compensated level is: with a big right-angle prism as horizontal glass () 1, with a rhombic prism as horizontal glass (two) 2, use them web member 3,4 to be fixed on the frame 5 of compensator respectively, be in relative static conditions with the compensator frame.The compensator frame is fixed on automatic compensated level inside, is in relative static conditions with its graticule.With two little right-angle prisms 6.1,6.2 bonding with optical flat 6.3 as index glass 6, and make the inclined-plane of two little right-angle prism vertical mutually, their one of them right angle faces are parallel to each other, their another right angle face sticks on the optical flat, is fixed on the pendulum mass 7.With hang spring 8 pendulum mass 7 is suspended on the compensator frame 5, pendulum mass is connecting damper 9, and index glass is subjected to the effect of gravity and damping force simultaneously.Stop 10.1-10.6 is set on the frame of compensator, and making pendulum mass is that the hunting range of index glass is restricted.Horizontal glass (one) is above the optical flat of index glass, and the inclined-plane of horizontal glass () is parallel with the optical flat of index glass, horizontal glass (two) is positioned at the side of right angle face of a little right-angle prism of index glass, one plane of horizontal glass (two) is parallel with this right angle face of this little right-angle prism, and vertical with the optical flat of index glass.
The compensator frame can be whole also can be split, but split frame each several part will be located the what relative static conditions.
The interior reflective surface of two fixed dynamic formula compensators are 6 (1) (2) (3) (4) (5) (6), but because the Brewster condition is all satisfied in each reflection, the requirement that the transmitance calculated value of whole telescopic system still can high what China's national standard (50%).
The compensator of these two fixed dynamic formula automatic compensated levels can be used for the different accuracy grade, different multiplying, the automatic compensated level of different size is used for satisfying that grade measurement of the level under the different condition, relative height are measured, needs and other corresponding request for utilization of measurement of azimuth.
The utility model also is applicable in all instruments that need the self leveling light path, and is as compensation.
