Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna structure technology, specifically to a Watson Watt direction-finding antenna that can be quickly deployed. Background Technology
[0002] The Watson-Watt direction-finding antenna is a commonly used direction-finding antenna in radar systems, widely applied in radio direction finding, positioning, and other fields. With its simple design and efficient pointing performance, it has become an important piece of equipment in military, meteorological, and communication systems.
[0003] Watson Watts direction-finding antennas typically include both shortwave and ultra-shortwave antenna sections to meet detection requirements. As a result, the overall length in the axial direction is relatively long. At the same time, both the shortwave and ultra-shortwave antenna sections extend outwards with ring antenna elements, resulting in numerous radial structures and a large overall width. This makes installation difficult and inefficient. Utility Model Content

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0026] Example
[0027] Please refer to Figures 1 to 4 This embodiment provides a rapidly deployable Watson-Watt direction-finding antenna, including an antenna body 10. The antenna body 10 includes a shortwave band 11, an ultra-shortwave band 12, and a control mechanism 13, which are sequentially and detachably connected. The shortwave band 11 includes a shortwave whip oscillator 111 and multiple shortwave ring oscillators 112. The shortwave whip oscillator 111 is slidably fitted with a slip ring 113. All the shortwave ring oscillators 112 are arranged in a ring around the shortwave whip oscillator 111. One side of each shortwave ring oscillator 112 is connected to the slip ring 113, and the opposite side is connected to the sidewall of the shortwave whip oscillator 111. The ultra-shortwave band 12 includes an ultra-shortwave whip oscillator 121. The device includes multiple ultra-shortwave ring oscillators 122, and an ultra-shortwave whip oscillator 121 slidably fitted with a slide plate 123. All the ultra-shortwave ring oscillators 122 are arranged in a ring around the ultra-shortwave whip oscillator 121. One side of each ultra-shortwave ring oscillator 122 is connected to the slide plate 123, and the opposite side is connected to the side wall of the ultra-shortwave whip oscillator 121. The sliding ring 113 can cause the ultra-shortwave ring oscillator 112 to bulge outward or retract inward along the radial direction of the ultra-shortwave whip oscillator 111. The sliding plate 123 can also cause the ultra-shortwave ring oscillator 122 to bulge outward or retract inward along the radial direction of the ultra-shortwave whip oscillator 121.
[0028] The rapidly deployable Watson-Watt direction-finding antenna provided in this embodiment is constructed by assembling the antenna body 10 into three detachably connected parts: a shortwave band 11, an ultra-shortwave band 12, and a control mechanism 13. This allows the antenna to be disassembled into three parts for transport, and axial deployment is convenient and rapid during installation. Furthermore, the shortwave band 11 includes a shortwave whip oscillator 111 and multiple shortwave ring oscillators 112, with a slip ring 113 and specific connection method. The slip ring 113 slides along the axial direction of the shortwave whip oscillator 111 to control the deployment or retraction of the shortwave ring oscillators 112 along the radial direction of the shortwave whip oscillator 111. Similarly, the ultra-shortwave band... The 12 includes a VHF whip oscillator 121 and multiple VHF ring oscillators 122, and is equipped with a slide plate 123 and a specific connection method. The VHF ring oscillators 122 are controlled to expand or contract in the radial direction of the VHF whip oscillator 121 by sliding the slide plate 123 along the axial direction of the VHF whip oscillator 121. During installation, the slide plate 123 is controlled to slide the slide ring 113, thereby controlling the shortwave ring oscillator 112 and the VHF ring oscillator 122 to expand conveniently and quickly. Through the combination of the above features, the rapidly deployable Watson-Watt direction-finding antenna can effectively solve the problems of high deployment difficulty and low deployment efficiency of existing rapidly deployable Watson-Watt direction-finding antennas.
[0029] It should be noted that the retraction and unfolding of the shortwave ring oscillator 112 and the ultra-shortwave ring oscillator 122 can be achieved by any of the existing technologies. For example, both are provided with elastic blocks, and the elastic blocks can be stretched radially and protruded by using the slip ring 113 and the slide plate 123 to squeeze them axially; or a hydraulic structure (such as a hydraulic telescopic rod) can be used, and the hydraulic structure can be pressurized by using the slip ring 113 and the slide plate 123 to extend the output end of the hydraulic structure, thereby driving the shortwave ring oscillator 112 and the ultra-shortwave ring oscillator 122 to unfold.
[0030] It should be noted that the control mechanism 13 mentioned above is used to realize the electrical functions of the antenna, which are all existing technologies and are the same as the control mechanism of the existing rapidly deployable Watson Watt direction finding antenna. Therefore, this part is not described in detail here.
[0031] Please refer to Figure 2To further explain the specific structure of the shortwave ring oscillator 112, the shortwave ring oscillator 112 includes a first ring oscillator 1121 and a second ring oscillator 1122; one end of the first ring oscillator 1121 is hinged to the slip ring 113; one end of the second ring oscillator 1122 is hinged to the free end of the corresponding first ring oscillator 1121, and the other end is hinged to the side wall of the shortwave whip oscillator 111; when the slip ring 113 moves along the shortwave whip oscillator... When the slip ring 111 slides so that the angle between the first ring oscillator 1121 and the corresponding second ring oscillator 1122 is acute or obtuse, the short-wave ring oscillator 112 bulges outward along the radial direction of the short-wave whip oscillator 111; when the slip ring 113 slides along the short-wave whip oscillator 111 so that the first ring oscillator 1121 and the corresponding second ring oscillator 1122 are parallel, the short-wave ring oscillator 112 retracts inward along the radial direction of the short-wave whip oscillator 111.
[0032] With the above settings, by sliding the slip ring 113, the angle between the first ring oscillator 1121 and the corresponding second ring oscillator 1122 can be changed, thereby controlling the shortwave ring oscillator 112 to bulge outward or retract inward.
[0033] To further shorten the length of the shortwave band 11 when it is folded up for easier transportation, the shortwave whip vibrator 111 includes an inner rod 1111 and an outer rod 1112 that are coaxially slidably fitted together. The slip ring 113 is coaxially slidably fitted onto the inner rod 1111 and fixedly connected to the end face of the outer rod 1112. The end of the inner rod 1111 away from the outer rod 1112 is coaxially connected to a first connecting post 114, which is used for detachable connection with the ultra-shortwave band 12. The end of the second ring vibrator 1122 away from the first ring vibrator 1121 is hinged to the end face of the first connecting post 114. When the shortwave whip vibrator 111 is in its shortest state, the first ring vibrator 1121 is parallel to the outer rod 1112, and the second ring vibrator 1122 is parallel to the first ring vibrator 1121. The angle between the first ring vibrator 1121 and the corresponding second ring vibrator 1122 is 0°.
[0034] With the above configuration, the shortwave whip oscillator 111 can contract axially, and its axial contraction process is linked with the radial contraction of the shortwave ring oscillator 112, so that the shortwave band 11 can simultaneously contract axially and contract radially, thereby further reducing the volume of the shortwave band 11 when it is contracted, and further facilitating transportation.
[0035] To radially limit and protect the shortwave ring vibrator 112 after it is folded up, a locking disc cover 115 is coaxially screwed to one end of the outer rod 1112 away from the inner rod 1111. The opening of the locking disc cover 115 is oriented towards the first connecting post 114. When the shortwave whip vibrator 111 is in its shortest state, the locking disc cover 115 can approach the hinge point between the first ring vibrator 1121 and the second ring vibrator 1122 along the axial direction and cover the hinge point between the first ring vibrator 1121 and the second ring vibrator 1122 through the opening.
[0036] With the above settings, when the shortwave ring vibrator 112 is retracted, the locking disc cover 115 is rotated to bring it closer to the inner rod 1111 along the axial direction of the outer rod 1112 until its cover covers the hinge joint between the first ring vibrator 1121 and the second ring vibrator 1122, thus protecting the hinge joint and limiting its radial movement.
[0037] Please refer to Figure 3 To further explain the specific structure of the VHF ring oscillator 122, the VHF ring oscillator 122 includes a third ring oscillator 1221 and a fourth ring oscillator 1222; one end of the third ring oscillator 1221 is hinged to the slide plate 123; one end of the fourth ring oscillator 1222 is hinged to the side wall of the VHF whip oscillator 121; the middle part of the third ring oscillator 1221 is hinged to the middle part of the corresponding fourth ring oscillator 1222 to form an X-shaped structure; when the slide plate 123... When the slide plate 123 slides along the ultra-short wave whip oscillator 121, making the angle between the third ring oscillator 1221 and the corresponding fourth ring oscillator 1222 acute or obtuse, the ultra-short wave ring oscillator 122 bulges outward along the radial direction of the ultra-short wave whip oscillator 121; when the slide plate 123 slides along the ultra-short wave whip oscillator 121, making the third ring oscillator 1221 parallel to the corresponding fourth ring oscillator 1222, the ultra-short wave ring oscillator 122 retracts inward along the radial direction of the ultra-short wave whip oscillator 121.
[0038] With the above settings, by sliding the slide 123, the angle between the third ring oscillator 1221 and the corresponding fourth ring oscillator 1222 can be changed, thereby controlling the ultra-shortwave ring oscillator 122 to bulge outward or retract inward.
[0039] To increase the receiving area of the third ring oscillator 1221 and the fourth ring oscillator 1222, the portion from the free end of the third ring oscillator 1221 to the hinge point extends along the width direction to form an arc plate structure; when the VHF ring oscillator 1222 is retracted, all the arc plate structures of the third ring oscillator 1221 are spliced into a cylindrical shape, and all the arc plate structures of the fourth ring oscillator 1222 are spliced into a cylindrical shape, with the two cylindrical structures coaxially arranged.
[0040] To prevent unnecessary rotation of the slide plate 123, the two ends of the ultra-shortwave whip oscillator 121 are coaxially connected to a second connecting post 124 and a third connecting post 125, respectively. The second connecting post 124 is used for a detachable coaxial connection with the first connecting post 114, and the third connecting post 125 is used for a detachable connection with the control mechanism 13. The slide plate 123 is vertically slidably connected to multiple guide rods 126, all of which are arranged in a ring around the ultra-shortwave whip oscillator 121. The two ends of the guide rods 126 are connected to the end faces of the second connecting post 124 and the third connecting post 125, respectively. The end of the fourth ring oscillator 1222 away from the third ring oscillator 1221 is hinged to the end face of the third connecting post 125.
[0041] By setting a second connecting post 124 and a third connecting post 125, which are detachably connected to the first connecting post 114 and the control mechanism 13 respectively; by setting multiple guide rods 126, the slide 123 is rotated and limited.
[0042] To limit and protect the two ends of the retracted ultra-short wave ring oscillator 122, a first locking ring 127 is coaxially screwed to one end of the second connecting post 124 near the third connecting post 125, and a second locking ring 128 is coaxially screwed to one end of the third connecting post 125 near the second connecting post 124. When the ultra-short wave ring oscillator 122 is retracted, the first locking ring 127 can be clamped to the outside of the end of the cylindrical tube spliced by the arc plate structure of all the fourth ring oscillators 1222, and the second locking ring 128 can be clamped to the outside of the end of the cylindrical tube spliced by the arc plate structure of all the third ring oscillators 1221.
[0043] With the above configuration, when the ultra-short wave ring oscillator 122 is retracted, rotating the first locking ring 127 and the second locking ring 128 will bring them close to and fit around the ends of the cylindrical tubes spliced by the arc plate structures of all the fourth ring oscillators 1222 and the ends of the cylindrical tubes spliced by the arc plate structures of all the third ring oscillators 1221, thereby limiting and protecting both ends of the retracted ultra-short wave ring oscillator 122.
[0044] To further explain the detachable connection structure of the shortwave band 11, the ultra-shortwave band 12, and the control mechanism 13, the end faces of the connecting ends of the first connecting post 114, the second connecting post 124, and the third connecting post 125 are all provided with positioning pins; the connecting ends of the first connecting post 114 and the third connecting post 125 are rotatably connected to a connecting ring 129, the inner wall of the connecting ring 129 is provided with internal threads, and the connection point between the connecting end of the second connecting post 124 and the control mechanism 13 is provided with external threads for screwing into the connecting ring 129.
[0045] With the above setup, the insertion angle is determined by the positioning pin, and the quick connector structure is formed by the connecting ring 129, so that the detachable connection can be achieved by screwing.
[0046] Preferably, the shortwave whip oscillator 111 and the ultra-shortwave whip oscillator 121 are coaxially arranged.
[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
