Abstract
The utility model relates to a portable ground surveillance radar which comprises a base cavity body and a cover body above the base cavity body. The base cavity body is internally provided with a servo system; and the servo system is mainly composed of a transmission shaft, a motor, and an encoder. The outside of the base cavity body is provided with radiating teeth; the motor and the encoder are coaxially arranged in the servo system and are respectively positioned at two sides of a bracket; and the base cavity body and the transmission shaft are connected through a rotating joint. The utility model has the advantages that: the motor and the encoder are mounted coaxially, so that the empty backhaul when the motor reverses is avoided, and the transmission accuracy of the servo system is enhanced; the base cavity body and the transmission shaft are connected through the rotating joint, so that the problem of the cable winding when the servo system works is avoided; and the heat dissipation of the whole radar adopts the closed conduction and natural convection cooling method, so that the high reliability and the low production cost are realized.
Description
Technical field
The utility model relates to a kind of portable type ground surveillance radar.
Background technology
Current border ground surveillance mainly realizes observation and the scouting of key area by optical device, owing to being subject to the restriction of the environmental factors such as weather, place, Optical Monitoring equipment exists many deficiencies, cannot meet the demand of all weather operations.With respect to Optical Monitoring equipment, it is far away that radar detection has operating distance, be not subject to environmental factor restriction and can long time continuous working etc. feature, can effectively make up the defect of optical device.
In existing radar servo system, power source is by reducing gear by the extremely final load of transmission of power, and to increase output torque, the gap yet driving-chain cannot disappear completely, all exists hysterisis error, and disappear gap cost and the gap effect exponent function relation that disappears.During Dui ground slow small target detection, servo-drive system needs frequent start-stop, turns to, and hysterisis error is larger on the transmission accuracy impact of servo-drive system.
Utility model content
For above-mentioned deficiency, it is high that the purpose of this utility model is to provide a kind of servo-drive system transmission accuracy, the portable type ground surveillance radar that production cost is low.
The technical solution of the utility model is achieved in that a kind of portable type ground surveillance radar, comprise base cavity and the cover body that is positioned at base cavity top, servo-drive system is installed in described base cavity, this servo-drive system is mainly comprised of transmission shaft, motor, scrambler, the external side of described base cavity is provided with radiation tooth, in described servo-drive system, support both sides are coaxially installed and laid respectively to motor and scrambler, and described base cavity is connected by rotary joint with transmission shaft.
Further, described servo-drive system also comprises bearing, described bearing inner race and transmission shaft wringing fit, and described bearing outer ring is connected with support assorted.
Further, described motor is direct current torque motor, and this motor inner ring is rotor, and outer ring is stator, and outer ring and support connect firmly, and inner ring and transmission shaft connect firmly.
Further, in described base cavity, be also provided with adapter flange, described base cavity and adapter flange are located by seam.
Further, described base cavity top is circular seam, and the sealing of this circle seam and cover body is fixedly connected.
Compared with prior art, the beneficial effects of the utility model are: adopt after said structure, because motor and scrambler are coaxially installed, the backlash phenomenon while having evaded motor reversal, has improved the transmission accuracy of servo-drive system.Base cavity is connected by rotary joint with transmission shaft again, the winding problem of cable while having avoided servo-drive system work.The heat radiation of radar complete machine adopts closed conduction and the natural convection type of cooling, have higher reliability, and production cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that this practicality is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of portable type ground surveillance radar as shown in Figure 1, comprises base cavity 1 and is positioned at the cover body 9 of base cavity 1 top, described base cavity 1 connects firmly with cover body 9 sealings, and described base cavity 1 provides support platform by adapter flange 5 for servo-drive system.This servo-drive system comprises motor 8, scrambler 3, transmission shaft 7, bearing 6.Described motor 8 and scrambler 3 are coaxially installed on transmission shaft 7, and motor 8 and scrambler 3 lay respectively at support 4 both sides, and dismounting is separate, changes unit easy operating; Described motor 8 is direct current torque motor, and this motor 8 is comprised of inner ring rotor and outer ring stator, and motor 8 inner rings and transmission shaft 7 connect firmly, and motor 8 outer rings and support 4 connect firmly, and bearing 6 inner rings and transmission shaft 7 connect firmly, and bearing 6 outer rings and support 4 connect firmly.This directly mode of driving has been eliminated hysterisis error, has improved the rotation precision of servo-drive system.Base cavity 1 is connected by rotary joint with transmission shaft 7, the winding problem of cable while having avoided servo-drive system work.
Described base cavity 1 outside is provided with radiation tooth 2, without using blower fan to carry out forced-convection heat transfer, whole aircraft reliability index and degree of protection is significantly improved, thereby evaded the adverse effect of border area extreme climate environment to equipment performance.And the whole hermetically sealed design of radar, for device interior components and parts provide good working environment, make it in the designed life time limit, as far as possible few safeguard or non-maintaining, except can independently bearing for a long time frontier defense security role, can also provide goal directed in earlier stage for border optical monitoring system.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
