Introduce embodiment of the present utility model with reference to the accompanying drawings:
The single-point inclinometer of taking pictures, as shown in drawings, the structure and the syntagmatic of each assembly are introduced in implementation in detail, and during enforcement, because this instrument is accurate, therefore, the assurance of machining accuracy and assembly precision is very necessary.Fishing spear 1, centralizer body 3, active joint 4, extension bar 5, joint 6, outer protection tube 9, joint 13, extension bar 14 and bumper assembly 15 all are to make with stainless steel material, and battery tube 22, sleeve 25, camera protective sleeve 26, measurement mechanism urceolus are to make with aluminium alloys and Cu alloy material.This instrument is to have the geometric properties at the basic principle of fixed directional and plummet and inclination angle and the design of the geometrical relationship between plummet drop point and direction according to magnetic compass, by the method for taking pictures the well bore parameter is taken on a circular egative film, after flushing is amplified, can read these numerical value easily.During work, battery is packed in the battery tube 22, in egative film chamber 28, put into circular egative film, connected the movement assembly and be contained on the Bunper assembly 8, adjust electronic timer according to the well depth position, with fishing spear, each assembly such as centralizer body connects successively puts into drilling rod, when arriving the precalculated position, camera is started working, because compass 34 fixed directional also remain horizontal level, plummet 32 remains the plumb position, and the annular tup of plummet 32 and compass surface forms fixing projection relation, through the exposure of bulb 29 plummet is photographed on the egative film through main lens 31 in the projection on the compass.Time for exposure is controlled by electronic timer, and the operator can hold manual time-keeping, can take out instrument after having taken, and unloads the movement assembly, in the darkroom, take out the egative film flushing after, can use and read the sheet device and read hole angle and azimuth parameter.It more than is the working method when measuring 0～20 ° of angle and adopting 0～20 ° of angle measuring device.When 15 °～90 ° angular measurements of needs, when the kludge core assembly, can replace 0～20 ° of angle measuring device with 15 °～90 ° angle measuring devices, the image-forming principle of this moment is, U type frame 43 remains horizontal level, calibration loop 42 remains the plumb position, after this instrument is stable in well, form fixing position relation between the graticule of U type frame 43 tops and the graduation mark on the calibration loop 42, this position concerns through main lens 41 and is photographed on the egative film by camera.Because the lower contact 21 of bumper assembly 15 is provided with flat groove through hole, therefore when inserting in the bit port, lower contact 21 do not influence the normal circulation of mud.
