Embodiment 1

[0022] Embodiment one, see figure 1 , a theodolite with a laser pointing structure heating type telescope, comprising a laser pointing mechanism 2 and a telescope 1.

[0023] The laser pointing mechanism 2 includes a laser 21 , a first reflective mirror 22 , a second light emitting mirror 23 and a plane mirror 25 . The first reflecting mirror 22 is a 90-degree reflecting mirror. The first reflecting mirror 22 reflects the light emitted by the laser at 90 degrees. The second light-emitting mirror 23 is a 90-degree reflective mirror, that is, it reflects the light reflected by the first reflective mirror by 90 degrees. The flat mirror 25 is installed in front of the objective lens of the telescope 1 . The second reflector 23 is connected to the center of the plane mirror 25 through photosensitive glue. The above are prior art.

[0024] The telescope 1 jacket is provided with a jacket 3 . Coat 3 is located in the circle. The jacket 3 comprises a first section 31 and a secon...

Embodiment 2

[0030] Embodiment two, the difference with embodiment one is:

[0031] see Figure 4 , the inner tube 4 includes an inner layer 45 and an outer layer 44 . The outer ring gear 51 is connected to the outer layer 44 . The inner tube 4 is connected together with the telescope through the outer layer in rotation. The inner layer 45 is spherically hinged within the outer layer 44 . The mirror layer 41 is provided on the inner surface of the inner layer 45 . The inner layer 45 protrudes from the inner surface of the outer layer 44 . During use, the inner layer 45 is rotated so that the light is irradiated on the mirror layer to the greatest extent and is reflected.

[0032] see Figure 5 , the laser pointing mechanism also includes an edge light collecting mirror 24 and a third mirror 28 . The laser 21 includes an LED laser tube 211 and a radiator 212 . The LED laser tube 211 is set vertically. The heat sink 212 is sleeved on the LED laser tube 211 for cooling the LED laser ...

Abstract

The invention relates to a theodolite, in particular to a theodolite with a heating type telescope with a laser alignment structure. The theodolite comprises a telescope and a laser alignment mechanism, wherein an outer sleeve is arranged outside the telescope in a sleeving manner; one end of the outer sleeve is connected with the telescope and provided with an air outlet, and the other end of theouter sleeve is penetrated with an inner tube and provided with an air inlet; one end of the inner tube and the outer sleeve are rotationally butted together, and the other end of the inner tube is rotationally connected with the telescope; a friction support section is arranged on the butting surface of the inner tube and the outer sleeve; the outer surface of the inner tube is provided with a fan blade for driving air flow to enter through the air inlet and then blow out from the air outlet; and a power mechanism for driving the inner tube to rotate is arranged inside the outer sleeve. Theinvention provides a theodolite with a heating type telescope with a laser alignment structure, which can heat the telescope when the ambient temperature is low, and solves the problem that the existing theodolite with the laser alignment structure cannot heat the telescope to resist a cold environment.

Description

technical field [0001] The invention relates to a theodolite, in particular to a theodolite equipped with a laser pointing structure heating type telescope. Background technique [0002] Theodolite can be widely used in third and fourth triangular control surveys of countries and cities, engineering surveys of railways, highways, bridges, water conservancy, mines, etc., and can also be used in various engineering surveys such as construction and large-scale equipment installation. In control survey and engineering survey, angle measurement is the most basic and most massive observation work, and precision electronic theodolite is the most commonly used tool for angle measurement at present. [0003] However, the theodolite telescope needs to be operated repeatedly during the target alignment process, especially the long-distance target alignment process, which brings inconvenience to use. The measurement of tunnels, culverts, mines, etc. is a highly dangerous job. Shortenin...
