Description

Technical Field

[0001] The utility model relates to the technical field of radar equipment, in particular to a braking device for a radar antenna. Background Art

[0002] Maritime radar is used for over-the-horizon monitoring and detection of the sea surface in the maritime and border defense fields. However, since the antenna length of the maritime radar is much larger than the length of the fixed part of the maritime radar, it is easily damaged by strong typhoons.

[0003] The utility model patent with patent application publication number CN 220556024 U discloses a braking device for a radar antenna, including a bracket, a radar antenna, a driving mechanism, a driving shaft, a brake disc and a limiting mechanism; the upper end of the bracket is rotatably connected to a rotating shaft, and a connecting disc is provided on the rotating shaft; the connecting disc is used to install the radar antenna; the driving mechanism includes a motor, a driving part and a fixing plate; the motor is installed on the bracket, the output end of the motor is connected to the driving part, the fixing plate is connected to the bracket, the driving shaft is rotatably connected to the fixing plate, the driving part is meshed with the driving shaft, the driving part is used to drive the driving shaft to rotate, and the upper end of the driving shaft is connected to the brake disc.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when adjusting the direction of the radar antenna, the above device uses a protrusion to move the limit rod. However, since there is only one protrusion, when the protrusion rotates away from the limit rod, the auxiliary disk is in a state of not being locked. At this time, the antenna is easily moved by the wind and the auxiliary disk is driven to change position, which in turn affects the normal adjustment of the antenna direction. The actual use effect is not ideal.

[0005] Therefore, it is necessary to invent a braking device for radar antenna to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a braking device for a radar antenna, which is provided with a braking mechanism and a shifting block so that the direction adjustment mechanism can be lifted when the shifting block is rotated, thereby releasing the braking state of the braking mechanism. After the direction adjustment mechanism drives the radar antenna to complete the direction adjustment, the braking mechanism drives the direction adjustment mechanism to move down and reset, thereby locking the direction adjustment mechanism again, and the radar antenna cannot rotate at this time, so as to solve the problem proposed in the above-mentioned background technology that when adjusting the direction of the radar antenna, the above-mentioned device uses a protrusion to shift the limit rod, but because there is only one protrusion, the auxiliary disk is in a state of lack of locking during the process of the protrusion rotating away from the limit rod. At this time, the antenna is easily driven by the wind to change the position of the auxiliary disk, thereby affecting the normal adjustment of the antenna direction, and the actual use effect is not ideal.

[0010] A radar antenna, wherein the radar antenna is fixedly arranged on the top of the direction adjustment mechanism;

[0011] A braking mechanism, the braking mechanism being used to brake the direction adjusting mechanism;

[0015] The driving mechanism comprises a shifting block, and a curved guiding surface is arranged on the top of the shifting block.

[0018] According to the brake device for a radar antenna of at least one embodiment of the present disclosure, the drive mechanism further includes a side plate, a drive motor, a transmission shaft, and a drive disk.

[0020] Technical effects and advantages of the utility model:

[0032] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0035] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0036] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0037] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0038] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0039] Figure 1 It is a schematic diagram of the overall structure of a braking device for a radar antenna according to an embodiment of the present disclosure.

[0040] like Figure 1-Figure 3 As shown, the braking device for the radar antenna of the present disclosure may include: a bracket 1, a direction adjustment mechanism 2, a radar antenna 3, a braking mechanism 4, a driving mechanism 5 and other components.

[0041] Figure 2 It is a schematic structural diagram of a direction adjustment mechanism 2, a braking mechanism 4 and a driving mechanism 5 of a braking device for a radar antenna according to an embodiment of the present disclosure.

[0042] Figure 3 1 is a schematic diagram of a partial structure of a braking mechanism 4 of a braking device for a radar antenna according to an embodiment of the present disclosure.

[0043] like Figure 2 As shown, in the present disclosure, the orientation adjustment mechanism 2 includes a rotating shaft 21, a rotating disk 22 and a lever 23, wherein the rotating shaft 21 is rotatably arranged at the top of the bracket 1, the rotating disk 22 is fixedly arranged at the top of the rotating shaft 21, and a plurality of levers 23 are arranged, and the plurality of levers 23 are evenly fixedly arranged at the bottom of the rotating disk 22.

[0044] Therefore, when the rotating shaft 21 is in a non-braking state and the lever 23 is pushed, the lever 23 drives the rotating disk 22 to rotate synchronously with the rotating shaft 21. When the rotating disk 22 rotates, it drives the radar antenna 3 to rotate, thereby helping the radar antenna 3 to adjust its direction.

[0045] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the braking mechanism 4 includes a movable block 41, a return spring 42, a limit ring 43, a limit groove 44 and a limit column 45, wherein the movable block 41 is rotatably arranged at the bottom of the rotating shaft 21 through a bearing, the return spring 42 is fixedly connected between the inner wall of the bracket 1 and the movable block 41, the limit ring 43 is sleeved and arranged on the outside of the rotating shaft 21 and is fixedly connected to the bracket 1, and a plurality of limit grooves 44 and limit columns 45 are provided, and a plurality of the limit grooves 44 are evenly opened at the top of the limit ring 43, and a plurality of the limit columns 45 are evenly fixedly arranged on the outside of the rotating shaft 21 and are respectively located on the inner sides of a plurality of limit grooves 44.

[0046] Therefore, under normal conditions, the plurality of limit posts 45 are respectively located on the inner sides of the plurality of limit slots 44, thereby braking the rotating shaft 21 and preventing the rotating shaft 21 from rotating at will. When the rotating shaft 21 cannot rotate, the radar antenna 3 located on the top of the rotating disk 22 also cannot rotate. When the rotating disk 22 moves upward, the rotating disk 22 drives the rotating shaft 21 to move upward synchronously. When the rotating shaft 21 moves upward, the reset spring 42 is stretched by the movable block 41, thereby driving the plurality of limit posts 45 to move out from the inner sides of the plurality of limit slots 44, thereby releasing the braking state. When the rotating disk 22 is reset subsequently, the plurality of limit posts 45 enter the inner sides of the plurality of adjacent limit slots 44 again, thereby completing the braking again.

[0047] like Figure 2As shown, in the present disclosure, the driving mechanism 5 includes a shift block 51, a side plate 52, a driving motor 53, a transmission shaft 54 ​​and a driving disk 55, wherein an arc-shaped guide surface is arranged on the top of the shift block 51, the side plate 52 is fixedly arranged on the top right side of the bracket 1, the driving motor 53 is fixedly arranged on the bottom of the side plate 52, the transmission shaft 54 ​​is transmission-connected with the driving motor 53, the driving disk 55 is fixedly arranged on the top of the transmission shaft 54, and the shift block 51 is fixedly arranged on the outside of the driving disk 55.

[0048] Therefore, after the driving motor 53 is started, it drives the driving disk 55 to rotate through the transmission shaft 54. When the driving disk 55 rotates, it drives the shift block 51 to rotate. When the shift block 51 rotates, it approaches the rotating disk 22. When the arc-shaped guide surface at the top of the shift block 51 contacts the bottom of the rotating disk 22, as the shift block 51 continues to rotate, the shift block 51 drives the rotating disk 22 to move upward, and then shifts the adjacent shift rod 23, so that the shift rod 23 drives the rotating shaft 21 and the rotating disk 22 to rotate, and the rotating disk 22 drives the radar antenna 3 to rotate, thereby completing the direction adjustment operation.

[0049] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.
