DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] The parabolic antenna structure of the utility model is as follows: Figures 1 to 5 As shown, it includes antenna disk components 1 spliced ​​along the circumferential direction. In other words, the parabolic antenna is formed by splicing a plurality of antenna disk components 1 along the circumferential direction. Figure 5 and Figure 6 As shown, the antenna plate assembly 1 includes a main reflective panel 11, an outer ring tube 12, an inner ring tube 13, a support rib 14, a reflective surface pressure strip 15, a panel support strip 16 and a middle ring tube 17. The main reflective panel 11 can be a mesh plate, such as Figure 7 As shown, the support rib 14 includes a radial rib plate 141, that is, when viewed along the central axis of the parabolic antenna, the radial rib plate 141 is extended along the radius direction of the parabolic antenna, and the upper and lower edges of the radial rib plate 141 are respectively welded with side plates 142, and the side plates 142 are perpendicular to the radial rib plate 141, so that the cross-section of the support rib 14 is in the shape of a groove shell, and an outer end ring 143 is provided at one end of the support rib 14, and an inner end ring 144 is provided at the other end of the support rib 14. The outer end ring 143 is welded to the radial rib plate 141 and the side plate 142, and the inner end ring 144 is welded to the radial rib plate 141 and the side plate 142. The outer end ring 143 is adapted to be mounted on the outer ring tube 12, and the outer end ring 143 is welded to the outer ring tube 12, and the inner end ring 144 is adapted to be mounted on the inner ring tube 13, and the inner end ring 144 is welded to the inner ring tube 13. Figure 5 and Figure 6 As shown, the support ribs 14 are circumferentially distributed, that is, for the parabolic antenna, the support ribs 14 are radially distributed, and the middle ring tube 17 is arranged between the outer ring tube 12 and the inner ring tube 13. In other words, the outer ring tube 12, the inner ring tube 13 and the middle ring tube 17 are concentrically arranged, and the middle ring tube 17 is adapted to pass through the radial rib plate 141. In other words, a circular through hole is provided in the middle of the radial rib plate 141, and the middle ring tube 17 is adapted to the above circular through hole, and the middle ring tube 17 is welded to the radial rib plate 141. Figure 5 As shown, the main reflective panel member 11 is laid on the support rib 14, the reflective surface bead 15 corresponds to the support rib 14, the main reflective panel member 11 is sandwiched between the reflective surface bead 15 and the side plate 142 (specifically, the side plate 142 located at the upper position), and the reflective surface bead 15 and the side plate 142 are connected by fasteners. For example, the reflective surface bead 15 and the side plate 142 are connected by rivets; Figure 6 As shown, the plate support strip 16 is disposed between the middle ring tube 17 and the outer ring tube 12, the plate support strip 16 is welded to the middle ring tube 17 and the outer ring tube 12, the plate support strip 16 is radially extended, the plate support strip 16 is disposed in the middle of adjacent support ribs 14, and the plate support strip 16 is attached to the lower side of the main reflective panel 11. Figure 1 and Figure 2 As shown, the radial ribs 141 of adjacent antenna disk assemblies 1 are fixedly connected by corresponding bolts, so that the main reflection panel members 11 are spliced ​​to form a parabola, specifically, the support ribs 14 located at both ends of the antenna disk assembly 1 along the circumferential direction are connected to the adjacent antenna disk assembly 1, such as Figure 7As shown, connecting columns 1411 may be welded to the radial ribs 141 of the support ribs 14 located at both end edges of the antenna plate assembly 1, and the above-mentioned bolts may coaxially pass through the connecting columns 1411 respectively belonging to two adjacent antenna plate assemblies 1.

[0022] Since the utility model is provided with support ribs 14 and combined with reflective surface strips 15 to fix the main reflective panel 11, the main reflective panel 11 is not easily deformed, and by providing the outer ring tube 12, the inner ring tube 13 and the middle ring tube 17, each support rib 14 can be reliably positioned, further improving the structural rigidity of the parabolic antenna and further avoiding deformation of the parabolic antenna. Figure 2 As shown, since the support ribs 14 are distributed radially, the positioning effect of the support ribs 14 on the outer part of the main reflector panel 11 (in the radial direction) is relatively weak. By setting the plate support strip 16, the main reflector panel 11 is prevented from having a significantly insufficiently supported part, and the main reflector panel 11 is prevented from being partially sunken when it is accidentally impacted during assembly or transportation. By setting the upper and lower edges of the radial ribs 141 to be welded with side plates 142 respectively, the torsion resistance of the support ribs 14 is increased, and the torsion deformation of the support ribs 14 is prevented. By setting the outer end ring 143 and the inner end ring 144, the support ribs 14 are further connected to the outer ring tube 12 and the inner ring tube 13. By setting the outer ring tube 12, the inner ring tube 13 and the middle ring tube 17 as a hollow structure, it is beneficial to reduce the weight of the parabolic antenna and facilitate transportation and installation. By setting the radial ribs 141 of the adjacent antenna plate components 1 to be fixedly connected by corresponding bolts, the assembly and disassembly of the parabolic antenna is convenient.

[0023] Furthermore, if Figure 5 As shown, the outer ring tube 12 is arranged outside the main reflection panel member 11, so the outer ring tube 12 has a better protective effect on the radial outer end of the main reflection panel member 11, and the radial inner end of the main reflection panel member 11 can be covered on the inner ring tube 13.

[0024] Furthermore, if Figure 4 As shown, the number of antenna disc components 1 is set to four, that is, the parabolic antenna can be roughly divided into four parts, and the four antenna disc components 1 can be stacked and packed, so that it is convenient to pack and transport, but it also avoids the cumbersome assembly caused by too many components. If the number of antenna disc components 1 is set to two, the maximum projection length of the antenna disc component 1 will be the diameter of the parabolic antenna, and the space occupied by the parabolic antenna during packaging and transportation will not be significantly reduced.

[0025] Furthermore, if Figure 7 As shown, hollow holes 1412 are formed on the radial ribs 141, which helps to reduce the weight of the parabolic antenna and facilitates transportation and installation.

[0026] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the parabolic antenna structure of the utility model also includes a central antenna plate 2, such as Figure 8 As shown, the central antenna dish 2 includes a sub-reflection panel member 21, an outer ring 22, a spoke support bar 23, an inner ring 24 and a mounting block 25. The sub-reflection panel member 21 can be a mesh plate, the inner ring 24 is concentrically arranged in the outer ring 22, and the spoke support bars 23 are circumferentially evenly distributed between the outer ring 22 and the inner ring 24, that is, the spoke support bars 23 are radially distributed, the sub-reflection panel member 21 is laid on the outer ring 22, the spoke support bars 23 and the inner ring 24, the sub-reflection panel member 21 can be welded with the outer ring 22, the spoke support bars 23 and the inner ring 24, the mounting block 25 is closely connected to the lower side of the sub-reflection panel member 21, and the mounting block 25 is welded to the outer ring 22, as shown in FIG. Figure 5 As shown, the inner ring tube 13 is welded with a mounting foot 3, during which the inner ring tube 13 can be arranged through the mounting foot 3, and the mounting foot 3 is formed with a connecting plate 31, as shown in FIG. Figure 1 and Figure 4 As shown, the central antenna plate 2 is arranged in the inner ring tube 13, as shown in FIG. Figure 3 As shown, the connecting plate 31 is fixedly connected with the corresponding mounting block 25 by corresponding screws, specifically, the mounting block 25 is attached to the upper side of the connecting plate 31, and the above-mentioned screws can pass through the connecting plate 31 from bottom to top and be screwed to the mounting block 25; the secondary reflector panel member 21 participates in forming the parabola. In order to increase the structural rigidity of the parabolic antenna, the volume of the support rib 14 and the inner ring tube 13 is set to be larger, and by setting the central antenna plate 2, it is avoided that the support rib 14 needs to converge to the central part of the parabolic antenna, that is, it is avoided that the central part of the parabolic antenna is too crowded with parts. Relatively speaking, since the projection diameter of the central antenna plate 2 is small, the outer ring 22, the spoke support bar 23 and the inner ring sleeve 24 can be set relatively small, and the deformation of the secondary reflector panel member 21 can also be avoided, so that the above-mentioned setting is conducive to making the parabolic antenna easy to manufacture. The inner ring sleeve 24 is used to install the bracket of the feed source.
