Embodiment 1

[0017] Embodiment one, see figure 1 , a theodolite provided with a heated telescope, comprising a telescope 1.

[0018] 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 second section 32 . The right end of the first section 31 is sealed and connected with the end where the eyepiece of the telescope 1 is located. The left end of the first section 31 is connected with the right end of the second section 32 . The left end of the second section 32 is sheathed on the left end of the inner tube 4 . The inner surface of the inner pipe 4 is a conical surface with a large left end and a small right end. The inner surface of the inner tube 4 is provided with a mirror layer 41 . The inner tube 4 is located at the end where the objective lens of the telescope is located. Fan blades 42 are arranged on the outer peripheral surface of the inner tube 4 . The right end of the inner tube 4 is rotatably ...

Embodiment 2

[0024] Embodiment two, the difference with embodiment one is:

[0025] 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.

Abstract

The invention relates to a theodolite, in particular to a theodolite provided with a heating type telescope. The theodolite comprises the telescope, wherein an outer sleeve is arranged outside the telescope in a sleeving way; one end of the outer sleeve is connected with the telescope and is provided with air outlet holes; an inner pipe is arranged in the other end of the outer sleeve in a penetrating way; the other end of the outer sleeve is provided with air inlet holes; one end of the inner pipe is rotationally abutted against the outer sleeve; the other end of the inner pipe is rotationally connected with the telescope; a friction support section is arranged on the butting surface of the inner pipe and the outer sleeve; fan blades for driving airflow to enter the theodolite through theair inlet holes and then to be blown out from the air outlet holes are arranged on the outer surface of the inner pipe; a power mechanism for driving the inner pipe to rotate is arranged in the outersleeve. The theodolite with the heating type telescope provided by the invention has the advantages that the telescope can be heated when the environment temperature is relatively low; the problem that the existing theodolite cannot heat the telescope for resisting the cold environment is solved.

Description

technical field [0001] The invention relates to a theodolite, in particular to a theodolite equipped with a heating 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. The existing theodolite also has the following disadvantages: when the ambient temperature is cold, it cannot be heated to increase the temperature, and the telescope in the theodolite will affect the observation effect when the ambient temperature is too high or too low. Contents of the invention [0003] The inve...
