The technical problem is solved by the following technical scheme: the utility model provides an establish theodolite that adds hot type telescope, includes the telescope, the telescope overcoat is equipped with the overcoat, the one end of overcoat is with the telescope links together and is equipped with in exhaust vent, the other end wear to be equipped with the inner tube and is equipped with the fresh air inlet, the one end of inner tube is together with the overcoat rotationally butt, the other end rotationally links together with the telescope, be equipped with the friction support section on the butt face of inner tube and overcoat, be equipped with the fan blade that the drive air current blew off from the exhaust vent after getting into through the fresh air inlet on the surface of inner tube, be equipped with drive inner tube pivoted power unit in the overcoat. The friction support section is the meaning that the support surface of the support section is a friction surface provided with a friction layer. When the telescope is used, when the environment temperature is too low and the observation effect of the telescope is influenced, the inner cylinder is driven to rotate through the power mechanism, and the fan blades generate wind when the inner cylinder rotates, so that the wind enters from the air inlet and flows through the surface of the telescope and then flows out from the air outlet. Owing to support through the friction support section between inner tube and the overcoat, so can produce the friction during the rotation and generate heat, the heat that the friction generates heat is taken to telescope surface by the wind and is realized the heating to the telescope.

Preferably, the power mechanism comprises an outer gear ring coaxially arranged with the inner pipe, a gear meshed with the outer gear ring and a motor driving the gear to rotate. When the gear is used, the motor drives the gear to rotate, the gear drives the outer gear ring to rotate, and the outer gear ring drives the inner pipe to rotate.

The term "mirror support section" is intended to mean that the support surface of the support section is a mirror surface, i.e. a smooth surface. During the use, when needs heat, fold the second section and first section and support through the friction support section to inner tube and overcoat along the axial of telescope, the air outlet is opened this moment, then drive power unit makes the inner tube rotate with the direction that the driving wind blew off from the exhaust vent to friction heat production and heat flow through the surface of telescope heat telescope. If the environment temperature is high, the second section and the first section are moved until the inner pipe and the outer sleeve are supported through the mirror surface supporting section, the air outlet is closed at the moment, and then the power mechanism is driven to enable the inner pipe to rotate in the direction that the driving air is blown out from the air inlet hole, so that the air between the outer sleeve and the telescope is pumped away to form vacuum, and the vacuum heat insulation effect is achieved.

Preferably, the inner tube is located at an objective end of the telescope, an inner surface of the inner tube is a conical surface, and a mirror layer is arranged on the inner surface of the inner tube.

Detailed Description

The invention is further described with reference to the following figures and examples.

First embodiment, referring to fig. 1, a theodolite with a heating telescope includes a telescope 1.

The telescope 1 is externally sleeved with an outer sleeve 3. The jacket 3 is located in a circle. The outer casing 3 comprises a first section 31 and a second section 32. The right end of the first section 31 is hermetically connected with the end of the eyepiece of the telescope 1. The left end of the first section 31 is joined to the right end of the second section 32. The left end of the second section 32 is sleeved on the left end of the inner tube 4. The inner surface of the inner tube 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 of the telescope where the objective lens is located. The outer peripheral surface of the inner pipe 4 is provided with fan blades 42. The right end of the inner tube 4 is rotatably and hermetically connected to the left end face of the telescope 1. The inner tube 4, the outer sleeve 3 and the telescope 1 enclose a cavity S. A power mechanism 5 is arranged in the cavity S. The power mechanism 5 includes an external ring gear 51, a gear 52, and a motor 53. The outer ring gear 51 and the inner tube 4 are coaxial. The outer ring gear 51 is connected to the right end of the inner tube 4. The gear 52 is engaged on the external ring gear 51. The motor 53 is used to drive the gear 52.

Referring to fig. 2, the second section 32 is provided with an inner cuff 321. The inner flange 321 is provided with an air inlet 322 communicating the cavity S and the external space. The inner circumferential surface of the burring 321 is provided with a first friction layer 323. The left end of the inner tube 4 is provided with a cylindrical support surface 43. The cylindrical support surface 43 is provided with a friction support section 431 and a mirror support section 432 which are sequentially distributed from left to right along the axial direction of the inner cylinder 4.

Referring to fig. 3, an annular groove 311 is provided on an end surface of the left end of the first section 31. The annular groove 311 extends circumferentially along the first segment. The left end of the first section 31 is also provided with a plurality of air outlets 312. The air outlet holes 312 are distributed along the circumferential direction of the first section. The air outlet hole 31 penetrates both side walls of the annular groove 311. The right end of the second section 32 is provided with an annular connector 324. The annular connector 324 is inserted into the annular groove 311.

Referring to fig. 1, 2 and 3, when heating is required, the second section 32 is slid along the axial direction of the telescope until the inward flange 321 is supported on the friction support section 431, and the air outlet 312 is in an open state. Then the gear 52 is driven by the motor 53 to rotate in the forward direction, the gear 52 drives the outer gear ring 51 to rotate in the forward direction, and the outer gear ring 51 drives the inner tube 4 to rotate in the forward direction. When the fan blade 42 rotates, friction is generated between the first friction layer 323 and the friction support section 431 to generate heat, and the fan blade 42 flows into the cavity S through the air inlet 322 and then flows out of the air outlet 312. When wind flows, heat generated by friction is transferred to the telescope 1 to heat the telescope.

When the temperature is too high and heat insulation is needed, the second section 32 is slid along the axial direction of the telescope to the inward flange 321 to be supported on the mirror surface supporting section 432, and at the moment, the depth of the annular connector 324 inserted into the annular groove 311 is increased to seal the air outlet 312. Then the gear 52 is driven by the motor 53 to rotate reversely, the gear 52 drives the outer gear ring 51 to rotate reversely, and the outer gear ring 51 drives the inner tube 4 to rotate reversely. The friction generated between the first friction layer 323 and the mirror support section 432 upon rotation is small, resulting in almost no heat generation. When the fan blade 42 is used, air in the cavity S is pumped out through the air inlet 322 to form vacuum, so as to perform the vacuum heat insulation function.

When heating and heat insulation are not needed, the rotation of the motor is stopped.

The second embodiment is different from the first embodiment in that:

referring to fig. 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 rotatably connected with the telescope through the outer layer. The inner layer 45 is spherically hinged within the outer layer 44. A 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. In use, the inner layer 45 is rotated to maximize the light incident on the mirror layer and reflected.
