Abstract
The utility model belongs to a stadia measuring tool and further relates to a leveling rod for night survey. The leveling rod for the night survey solves the problem that a precise leveling rod is not provided with a matched illumination device at present. The leveling rod for the night survey comprises a leveling rod body 1, an illumination device 2 located on one side of a scale panel of the leveling rod and a power supply 3 connected with the illumination device. Compared with the prior art, the leveling rod for the night survey has the advantage that a light source reflects light evenly, instrument reading is prevented from being influenced due to the fact that the light is radiated on leveling rod body scales directly, and light is even in irradiation and moderate in luminance.
Description
Technical field:
The invention belongs to the tacheometric survey instrument, further relate to a kind of exploration at night levelling pole.
Background technology:
Along with the continuous maturation of high ferro technology, the high-speed railway in the operation needs follow-up observation, to guarantee its security, regularity and stability.The follow-up observation of high ferro is on the basis that does not affect the operation on daytime, must observe at night, present precision level can't carry out reading to levelling pole in the situation of gauge without light source at night, cause to carry out data observation, so must be equipped with light fixture to levelling pole.Traditional way is artificial light, and flashing causes spirit-leveling instrument read untrue or reading not surely, and cost of labor is high.Therefore be badly in need of the observation requirement that a kind of light fixture that can be fixed on the levelling pole satisfies spirit-leveling instrument, and can adjust along with levelling pole length, it is lightly convenient to require, the light irradiation is uniform and stable, be convenient to instrument readings, satisfy the accuracy requirement of different model electronic level, can mate different brackets actual measurement length needs, labor savings reduces cost.
Summary of the invention:
The present invention is directed to present precise levelling rod does not have this vacancy of supporting light fixture, and light and handy convenient, uniform and stable, the robust precise levelling rod dedicated illumination equipment of light of the energy-saving and emission-reduction of a kind of human oriented design that proposes, profile.The present invention is achieved through the following technical solutions:
Night, levelling pole was used in exploration, and comprising: levelling pole body 1 also comprises: be positioned at the lighting device 2 of levelling pole body scale panel one side, the power supply 3 that links to each other with lighting device.
Described lighting device comprises: be positioned at levelling pole body scale panel the place ahead, a reflector 11 in levelling pole body scale side the place ahead is between reflector and levelling pole body scale panel and the single lamp 4 of equally distributed N LED; The single lamp of described N LED be spaced apart 1-4cm; The light of the single lamp of described N LED disperse axis parallel, and jointly be parallel to levelling pole body scale panel; Described N the single lamp of LED blocked fully by reflector for the gauger, and be invisible; The operating voltage of the single lamp of the LED of described lighting device is the 3-3.2 volt, and electric current is less than or equal to 10 milliamperes; Described power supply is positioned at top, levelling pole body back, interposition is equipped with the light source 13 of independent a sent Shu Guang under power supply, this light positive can project well the horizontal bubble 14 that is positioned at levelling pole body back, is used for guaranteeing that the levelling pole body places perpendicular to surface level.
The present invention is with respect to the advantage of prior art:
(1) light source is evenly reflective, and avoiding shining directly on the levelling pole body scale affects instrument readings, make light irradiation evenly, brightness is moderate.
(2) the LED lamp is very energy-conservation, and the levelling pole power consumption of 1 meter length can use more than 10 hours continuously less than or equal to 1.5 watts, and 2 meters light fixture power consumption can use more than 6 hours continuously less than or equal to 3 watts, and single is long service time, and the cycle in serviceable life is long.
(3) be specially provided with the bubble illuminating lamp at power supply, having solved to have a people to adjust bubble in the practical operation, and the problem of personal responsibility illumination has realized just finishing all operations by a people, has saved manpower, has reduced materials cost.
