[0001] The utility model belongs to the field of course beacon antenna, concretely relates to course beacon antenna. BACKGROUND

[0002] Instrument landing system is the main use of our country civil aviation airport at present Landing guidance system And course beacon antenna belongs to instrument landing system part. The course beacon antenna is usually installed on the extension line of the runway, so birds, bees and other insects often appear near the course beacon antenna. When insects and animals move near the course beacon antenna, sand and insects and other foreign matters often enter the connecting gap between the antenna array and the antenna frame, thereby affecting the stability of the signal and the landing safety of the aircraft.

[0003] In the prior art, in order to prevent foreign matters from entering the connecting gap between the antenna array and the antenna frame, glue is often filled in the connecting gap between the antenna array and the antenna frame, and the connecting gap is blocked by the glue, thereby avoiding the entry of foreign matters. However, since the course beacon antenna is installed outdoors, the glue is prone to cracking or falling off after long-term wind and rain, and cannot play a long-term sealing effect on the connecting gap. When the glue cracks or falls off, foreign matters will enter the connecting gap between the antenna array and the antenna frame. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides course beacon antenna, its purpose is to solve the problem of foreign matter entering course beacon antenna.

[0005] In order to achieve the above purpose, the utility model provides a foreign matter preventing baffle, including baffle body, the baffle body is annular;

[0006] The baffle body is structured with an opening, the opening disconnects the baffle body, and a connecting structure is arranged at the opening, and the connecting structure is used to connect the two sides of the opening.

[0007] The baffle body in the scheme is annular, which can be applied to the course beacon antenna, and the connection between the antenna array and the antenna frame is shielded, thereby avoiding the entry of foreign matters into the course beacon antenna. The deficiencies of the prior art are solved.

[0008] At the same time, the baffle in the scheme can be disconnected through the opening and connected and fixed through the connecting structure. Therefore, the baffle in the scheme can be directly installed at the required position, which is more efficient, and compared with moving the baffle to the corresponding position, the baffle can be more closely connected with the course beacon antenna.

[0009] Preferably, in order to realize the connection of the two sides of the opening, the connecting structure comprises a first connecting part and a second connecting part, the first connecting part and the second connecting part are arranged on the two sides of the opening respectively, and the first connecting part and the second connecting part are connected to realize the connection of the two sides of the opening.

[0010] In the present application, the first connecting part and the second connecting part are arranged, and when the first connecting part and the second connecting part are connected, the two sides of the opening can be connected. After the two sides of the opening are connected, the blocking ring body cannot be disconnected freely.

[0011] Preferably, in order to realize the stable connection of the first connecting part and the second connecting part, the first connecting part is a first connecting protrusion, the second connecting part is a second connecting protrusion, and the first connecting protrusion and the second connecting protrusion are embeddedly connected.

[0012] Preferably, in order to facilitate the separation of the first connecting protrusion and the second connecting protrusion, the surfaces of the first connecting protrusion and the second connecting protrusion are arc-shaped.

[0013] When the first connecting protrusion and the second connecting protrusion are arc-shaped, the first connecting protrusion and the second connecting protrusion can slide relative to each other when receiving external force, and finally the first connecting protrusion and the second connecting protrusion are separated.

[0014] Preferably, the opening is an oblique opening.

[0015] Preferably, in order to ensure that the blocking ring body can be more fitted to the gap, at least one end of the blocking ring body is a plane.

[0016] The second aspect of the utility model discloses a heading beacon antenna, comprising the above-mentioned anti-foreign matter blocking ring, antenna frame and antenna array, the antenna frame is constructed with the installation mouth, the antenna array is installed in the installation mouth, the anti-foreign matter blocking ring is installed in the antenna array, and the anti-foreign matter blocking ring blocks the gap between the installation mouth and the antenna array.

[0017] Preferably, in order to prevent the anti-foreign matter blocking ring and the antenna array from having a gap, the inner diameter of the anti-foreign matter blocking ring is not greater than the diameter of the antenna array.

[0018] When the anti-foreign matter blocking ring is installed on the antenna array, there is no gap between the anti-foreign matter blocking ring and the antenna array, so that foreign matters cannot enter from the anti-foreign matter blocking ring and the antenna array. At the same time, the anti-foreign matter blocking ring and the antenna array can be connected more stably, and the anti-foreign matter blocking ring can be prevented from moving due to external force.

[0019] Preferably, in order to ensure that the foreign matter blocking ring can completely block the gap between the mounting port and the antenna array, the thickness of the foreign matter blocking ring is greater than the height of the gap between the mounting port and the antenna array.

[0020] The foreign matter blocking ring completely blocks the gap between the mounting port and the antenna array, and the foreign matter blocking effect is better.

[0021] The foreign matter blocking ring completely blocks the gap between the mounting port and the antenna array, and the foreign matter blocking effect is better.

[0022] Secondly, in the present application, the opening and the connecting structure are used to mount the blocking ring body on the heading beacon antenna. Compared with not setting the opening and the connecting structure, i.e., setting the blocking ring body as a complete ring, the blocking ring body can be more conveniently mounted on the required position of the heading beacon antenna, and the effect is higher. At the same time, if the blocking ring body is set as a complete ring, the inner ring of the blocking ring must be set to be slightly larger than the mounting position, so that the blocking ring can be slid to the required position. Obviously, the inner ring of the blocking ring is prone to have a gap. BRIEF DESCRIPTION OF DRAWINGS

When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] In the present disclosure, the orientation words such as "inner" and "outer" are defined according to the contour of the corresponding parts themselves unless otherwise stated. The terms such as "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.

[0035] Embodiment 1

[0036] Basically as shown in the accompanying Figure 1 to the accompanying Figure 2 , a foreign matter blocking ring is mainly used for installation to a heading beacon antenna to prevent foreign matter from entering the heading beacon antenna.

[0037] As shown in the accompanying Figure 1 , the foreign matter blocking ring of the present embodiment includes a blocking ring body 1, which is specifically in the shape of a ring and can be made of a composite material of ring hydrogen resin or polyethylene fiber. At least one end surface of the blocking ring body 1 is a flat surface, and more preferably both end surfaces of the blocking ring body 1 are flat surfaces. Since the end surface of the blocking ring body 1 is a flat surface, when the blocking ring body 1 is installed to the heading beacon antenna, the blocking ring body 1 can be more closely fitted to the blocked gap surface, and the sealing effect of the gap is better.

[0038] In the present embodiment, the blocking ring body 1 is provided with an opening 11, which is preferably an oblique opening. The opening 11 disconnects the ring-shaped blocking ring body 1, and when the two sides of the opening 11 move away from each other, the gap between the openings 11 can be used for the heading beacon antenna to pass through, thereby achieving installation of the blocking ring body 1 to the heading beacon antenna.

[0039] As shown in the accompanying Figure 2 and Figure 3 , in the present embodiment, the opening 11 is preferably an oblique opening. The oblique opening can be laterally transversely offset, thereby achieving opening of the blocking ring body 1, as shown in the accompanying Figure 3 ; or the oblique opening can also be offset in the vertical direction, thereby achieving opening of the blocking ring body 1, as shown in the accompanying Figure 4As shown.

[0040] It should be noted that the opening 11 is provided as an inclined opening in this embodiment, but in some other embodiments, the opening 11 can also be a horizontal opening. As Figure 5 As shown.

[0041] In this embodiment, the disconnection part of the retainer ring body 1 is provided with a connecting structure, and the disconnected retainer ring bodies 1 are connected together through the connecting structure. As Figure 2 and Figure 3 As shown, the connecting structure in this embodiment specifically includes a first connecting part 12 and a second connecting part 13, and the first connecting part 12 and the second connecting part 13 are respectively arranged on both sides of the opening 11. In this embodiment, the first connecting part 12 is preferably a first connecting protrusion, which is in the shape of a circular arc. At the same time, the second connecting part 13 is a second connecting protrusion, which is also in the shape of a circular arc. When the first connecting part 12 and the second connecting part 13 are embedded in each other, the first connecting part 12 and the second connecting part 13 are connected. After the first connecting part 12 and the second connecting part 13 are connected, the connection of both sides of the opening 11 is realized.

[0042] It can be understood that the first connecting protrusion and the second connecting protrusion are both provided in the shape of a circular arc, so that when it is necessary to disconnect the first connecting protrusion and the second connecting protrusion, the first connecting protrusion and the second connecting protrusion can be more conveniently disconnected. However, if the problem of whether to facilitate disconnection is not considered, the first connecting protrusion and the second connecting protrusion can also be provided in the shape of a taper, as Figure 6 As shown.

[0043] Of course, this embodiment provides a way of connecting structure, but in other embodiments, the connecting structure can also be in other forms. For example, the first connecting part 12 can be provided as a circular protrusion, and the second connecting part 13 can be provided as a circular groove. The circular protrusion can be embedded into the circular groove, thereby realizing the stable connection of the first connecting part 12 and the second connecting part 13, as Figure 7 As shown.

[0044] It should be noted that it is more preferred in this embodiment to provide the opening 11 to be offset in the vertical direction, so as to realize the opening of the retainer ring body 1 (i.e. Figure 4 As shown.

[0045] Embodiment 2

[0046] This embodiment is improved on the basis of Embodiment 1, as Figure 8As shown, when the opening of the retaining ring body is an inclined opening and the opening opens from the vertical direction, in order to ensure that the retaining ring body 1 will not detach from the heading beacon antenna at the opening 11 due to fatigue deformation during long-term use.

[0047] This embodiment also includes a pin hole at the opening of the retaining ring body, extending from one end face of the foreign object protection retaining ring to the other side of the opening 11. A pin can be inserted into the pin hole; preferably, the pin is made of plastic to avoid interference with the antenna array. This embodiment strengthens the connection and fastening on both sides of the opening 11 through the cooperation of the pin hole and the pin, preventing the retaining ring body 1 from separating at the opening and avoiding detachment of the retaining ring body 1 from the heading beacon antenna. Simultaneously, to avoid the end of the pin hole affecting the sealing effect of the foreign object protection retaining ring, the length of the pin is less than the width of the foreign object protection retaining ring. Therefore, when the pin is inserted into the pin hole, the end of the pin will not protrude from the other end of the retaining ring body 1, preventing gaps between the retaining ring body and the heading beacon antenna due to the end of the pin hole.

[0048] Example 3

[0049] This embodiment discloses a heading beacon antenna, such as Figure 9 As shown, the antenna includes an antenna frame 2, an antenna array 3, and the foreign object protection ring as described in Embodiment 1 or Embodiment 2. In this embodiment, the antenna frame 2 includes a column and a mounting bracket. The column is fixedly installed, and the mounting bracket is welded or fitted with fasteners to the top of the column. The mounting bracket has a circular mounting opening, inside which the antenna array 3 is installed. The antenna array 3 is cylindrical. When the antenna array 3 is installed inside the mounting opening, a gap exists between the opening and the antenna array 3, allowing external impurities to easily enter.

[0050] In this embodiment, a foreign object blocking ring is fitted onto the antenna array 3. The inner diameter of the foreign object blocking ring is the same as the inner diameter of the antenna array 3, thereby avoiding gaps between the foreign object blocking ring and the antenna array 3, and making the installation of the foreign object blocking ring more stable. At the same time, the foreign object blocking ring is installed at the opening of the mounting port, effectively blocking the connection gap between the mounting port and the antenna array 3, preventing foreign objects from entering.

[0051] In this embodiment, the thickness of the anti-foreign object shielding ring is greater than the height of the gap at the mounting opening. Therefore, after the anti-foreign object shielding ring is installed on the antenna array 3, it can completely block the gap and prevent foreign objects from entering.

[0052] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much here. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
