A spectrum radio direction finder

Abstract

The present invention provides a spectrum radio direction finder, comprising a box body, wherein two electric telescopic rods are fixedly connected at the center of one side of the inner bottom of the box body. The present invention arranges an electric push rod, a U-shaped plate, a movable rod and a fixed rod, so that the U-shaped rod can be lifted and lowered by telescoping the electric push rod, and then the fixed rod is driven to move by the rotation connection between the U-shaped plate and the movable rod, and the rotation through connection between the movable rod and the fixed rod. At the same time, since the fixed rod is connected to a door panel, and the door panel is rotationally connected to a through groove, when the U-shaped plate is lifted and lowered, the two door panels can be automatically opened and closed, thereby ensuring that the omnidirectional antenna can be erected smoothly, and when the omnidirectional antenna is stored, the through groove is closed to prevent rainwater from entering the box body and causing damage to the equipment.

Description

Technical Field

[0001] The invention relates to the technical field of radio direction finding, and in particular to a spectrum radio direction finder. Background Art

[0002] Radio direction finding represents two practical methods of two disciplines. In the ship communication and navigation discipline of marine engineering, it represents the method of determining the direction by measuring the arrival direction or other characteristics of the radio signal. In the avionics and airborne computer system discipline of aviation technology, it represents the method of using a radio direction finder to measure the location of the radio transmitter.

[0003] A radio direction finder is usually installed at a specific location, such as on a ship or a vehicle. When in use, it receives and sends radio waves through an antenna. Existing radio direction finders are directly exposed to the air when not in use, which makes it easy for water or dust to enter the internal structure of the radio direction finder, thereby causing damage to the circuit of the radio direction finder and affecting the working accuracy of the radio direction finder.

[0004] Therefore, it is necessary to provide a spectrum radio direction finder to solve the above technical problems. Summary of the invention

[0005] The technical problem solved by the present invention is that the existing radio direction finder is directly exposed to the air when not in use, which makes it easy for water or dust to enter the internal structure of the radio direction finder, thereby causing damage to the circuit of the radio direction finder and affecting the working accuracy of the radio direction finder. A spectrum radio direction finder is provided.

[0006] In order to solve the above technical problems, the present invention provides a spectrum radio direction finder, including a box body, two electric telescopic rods are fixedly connected to the center of one side of the inner bottom of the box body, and the telescopic ends of the two electric telescopic rods are rotatably connected to disks, the side walls of the disks are fixedly connected to two mounting blocks, and the opposite side walls of the two mounting blocks are rotatably connected to connecting rods, one side of the connecting rod is fixedly connected to a connecting seat, two mounting plates are fixedly connected to the other side of the inner bottom of the box body, and the opposite side walls of the two mounting plates are rotatably connected to support columns, the front surface of the support column is rotatably penetrated by a connecting shaft near the bottom position, and through holes are respectively opened at the front and rear sides of the axial surface of the connecting shaft, and cylindrical blocks are arranged inside the through holes;

[0007] A through slot is opened at the top center of the box body, and the front surface and rear surface of the through slot are rotatably connected to door panels respectively, and a fixing rod is fixedly connected to the top position of one side surface of the door panel, an electric push rod is fixedly connected to the center of the outer surface of one side of the box body, and the telescopic end of the electric push rod is fixedly connected to a U-shaped plate, and the opposite side walls of the U-shaped plate are rotatably connected to two movable rods.

[0008] Preferably, a water guide groove is opened at the inner bottom edge of the box body, and a through groove is opened at the bottom position of one side of the inner surface of the box body, a shell is fixedly connected to the outer surface of the box body at the position of the through groove, and a dustproof net is fixedly connected to the inner side of the shell.

[0009] Preferably, an exhaust duct is connected to an outer surface of one side of the box body near the rear side, and an exhaust fan is fixedly connected to an inner side of the exhaust duct.

[0010] Preferably, an omnidirectional antenna is fixedly connected to the top of the support column, and the omnidirectional antenna is slidably connected to the inner wall of the through slot.

[0011] Preferably, two connecting seats are provided, and the opposite side walls of each connecting seat are fixedly connected to the two end surfaces of the adjacent cylindrical block.

[0012] Preferably, the two movable rods are respectively arranged at the front and rear sides of the U-shaped plate, and the top of each movable rod is rotatably connected with the adjacent fixed rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention provides an electric push rod, a U-shaped plate, a movable rod and a fixed rod, so that the U-shaped rod can be lifted and lowered by retracting the electric push rod, and the fixed rod can be driven to move by the rotational connection between the U-shaped plate and the movable rod, and the rotational through-connection between the movable rod and the fixed rod. At the same time, since the fixed rod is connected to the door panel, and the door panel is rotationally connected to the through slot, when the U-shaped plate is lifted and lowered, the two door panels can be automatically opened and closed, thereby ensuring that the omnidirectional antenna can be erected smoothly, and when the omnidirectional antenna is stored, the through slot is closed to prevent rainwater from entering the box and causing damage to the equipment;

[0015] (2) The present invention provides an electric telescopic rod, a connecting rod and a supporting column, so that the disc can be moved by extending the electric telescopic rod, thereby realizing the position movement of one end of the connecting rod. Since the length of the connecting rod remains unchanged, when one end of the connecting rod realizes horizontal linear movement under the extension of the electric telescopic rod, the other end of the connecting rod is fixedly connected to the connecting seat, and the fixed seat is rotatably connected to the cylindrical block, so that the cylindrical block can be restricted by the through hole to realize the angle adjustment of the supporting column with the rotation point of the mounting plate as the center, thereby realizing the storage of the omnidirectional antenna into the box;

[0016] (3) The present invention sets a disc, a mounting block, a connecting shaft and a cylindrical block. As the angle of the support column is adjusted during the storage process, the height of the connecting shaft is continuously adjusted, and as the position of the disc moves, one end of the connecting rod is driven to move, so that the angle between the connecting rod and the support column and the angle between the connecting rod and the electric telescopic rod change. Therefore, the connecting rod can be smoothly adjusted in angle through the rotational connection between the connecting rod and the mounting block, and the connecting rod and the cylindrical block. Moreover, the rotational connection between the disc and the telescopic end of the electric telescopic rod, and the rotational connection between the connecting shaft and the support column can ensure that the connecting shaft can rotate independently as the height of the connecting shaft is adjusted, thereby ensuring that the center line of the connecting shaft, the center line of the disc and the center line of the connecting rod are always in the same plane, thereby ensuring the smooth movement of the connecting rod.
