Abstract

A disc type electric rail satellite antenna consists of a dish surface (1), an elevation angle adjusting rod (2), a bracket (3), an electric push rod and a base. The base consists of an upper disc (4) and a lower disc (5). The electric push rod consists of a decelerating motor (6), screw rod (7) and push rod (8). A hollow rail (10) is erected on arc edge of the lower disc (5), with height consistent with elevation angle of the satellite antenna. The electric push rod drives back-and-forth movement of the screw rod (7) via the decelerating motor (6), and further drives the upper disc (4) to rotate along the hollow rail (10). Adjusting work can be accomplished by only adjusting elevation angle of one satellite for receiving signal. In the utility model, receiving signal is tuned by adjusting height of the hollow rail, so the utility model has the advantages of simple adjusting, time saving, high signal receiving precision, simple integral structure, firm disc base, strong wind resistance, simple circuit, low manufacture cost, easy quality guarantee, and easy popularization.

Description

The electronic rail satellite antenna of disc type

Technical field

The utility model relates to the satellite-signal receiving equipment, exactly belongs to the satellite signal receiving antenna field.

Background technology

Along with the overhead synchronous satellite in equator is more and more, a surface antenna is difficult to satisfy the demand that many synchronous satellite signals receive, if receive the multi-satellite signal a plurality of antennas need be installed, and the cost height, and it is big to take up space.Present existing reception antenna has polar mounts, twin axle, can solve the hope that a surface antenna receives multi-satellite basically, but these two kinds of antenna structure complexity, debugging difficulty is big, and the cost height.Usually, the polar mounts satellite antenna has three important angles---the elevation angle, due south, pole axis angle and offset angle, these three angles need to adjust repeatedly in debug process, because two universal joints are arranged on the push rod of pole axis satellite antenna, when wind is arranged, be easy to move, and its reception pot moves on inclined shaft, it is very heavy to accept pot load when both sides, burn out motor easily or damage gear, so its power of motor is big, the cost height.And twin axle satellite antenna debugging is simple, but the angle of each satellite that need receive all must be adjusted during debugging, and it has two cover reducing motors, controls the elevation angle and azimuth respectively, a whole set of cost height.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, debugging convenience, received signal precision height, the electronic rail satellite antenna of disc type that cost is low.

The technical solution adopted in the utility model is: be made up of pot face, elevation angle adjusting rod, support, electric pushrod and base, base is made up of last dish and lower wall, electric pushrod is made up of reducing motor, screw mandrel, push rod, on the arc edge of base lower wall, erect a hollow tracl, the height of hollow tracl is consistent with the elevation scale of satellite antenna, in debug process, only need the harmonize elevation scale of a satellite of received signal can be finished debugging work.

Beneficial effect: received signal of the present utility model is to debug out by the height of hollow tracl, so when debugging be simple, save time, received signal precision height, and overall structure is simple, the disc type base is firm, wind resistance power is strong, circuit is simple, low cost of manufacture, quality guarantee easily, very easily popularize.

Description of drawings

The utility model specification has two width of cloth accompanying drawings, and the drawing of this accompanying drawing is described as follows:
