DETAILED DESCRIPTION

[0038] The core of the utility model is to provide an interference device and an integrated detection and interference device. Inclined heat dissipation fins are provided on the outer surface of the box, which ensures a good heat dissipation effect for each power amplifier module in the interference device, thereby ensuring the reliability of the interference device.

[0039] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0041] The jamming device involved in this application is mainly used to detect and interfere with unauthorized or non-compliant drones in a specific airspace.

[0042] In a specific embodiment of the present application, the interference device may include:

[0043] Box 1;

[0044] A power amplifier module 5 is provided inside the box 1;

[0045] An antenna 4 is provided outside the box 1 and connected to the power amplifier module 5;

[0046] The heat dissipation fins 2 are arranged on the outer surface of the box body 1 , and are strip-shaped fins arranged obliquely relative to the extension direction of the antenna 4 .

[0047] like Figure 1 As shown, the box body 1 in this embodiment is roughly a rectangular structure, which includes a first shell 11 and a second shell 12 that can be opened and closed; the power amplifier module 5 is arranged inside the box body 1, and is generally fixed to the inner surface of the box body 1. In an optional embodiment of the present application, a main control module and a detection module can also be integrated in the box body 1; at the same time, the antenna 4 can include a receiving antenna and a transmitting antenna, wherein the receiving antenna is connected to the detection module for detecting radio frequency signals in the airspace; the transmitting antenna is connected to the power amplifier module 5 for outputting interference signals into the airspace; thus, the interference device in the present application can form a detection and interference integrated device that integrates detection and interference functions. In addition, whether it is a receiving antenna or a transmitting antenna, in the actual working process, the length of the receiving antenna and the transmitting antenna are extended in the vertical direction, thereby ensuring that the antenna 4 can better receive and send signals.

[0048] In order to dissipate heat from the various amplifier modules within the enclosure 1, in this embodiment, heat dissipating fins 2 are provided on the outer surface of the enclosure 1. It will be appreciated that the enclosure 1 in this embodiment preferably utilizes a housing formed of a material with excellent heat dissipation properties, and the heat dissipating fins 2 on the outer surface of the enclosure 1 may be directly integrally formed with the enclosure 1, or may be a structure made of a different material than the enclosure 1 and bonded to the outer surface of the enclosure 1 by means such as bonding, as long as good thermal conductivity is ensured between the heat dissipating fins 2 and the enclosure 1.

[0049] As described above, the enclosure 1 in this embodiment is generally a flat rectangular parallelepiped structure, having two largest side surfaces. The power amplifier module 5 can be centrally located on the inner surface of one of the largest side surfaces of the enclosure 1. If the main control module and detection module are integrated within the enclosure 1, they can be integrated on the inner surface of the other largest side surface. Based on this, the heat dissipation fins 2 are also located on the outer surfaces of the two largest side surfaces.

[0050] In order to further enhance the heat dissipation effect of the heat dissipation fins 2, the heat dissipation fins 2 are tilted in this embodiment. It is understood that the heat dissipation fins 2 are tilted in this embodiment so that when the antenna 4 extends in the vertical direction, the extension direction of each heat dissipation fin 2 on the outer surface of the box body 1 is tilted relative to the vertical direction and the horizontal direction. Figure 1 and Figure 2 As shown, when the heat dissipating fins 2 of the box body 1 in the present application are tilted, the flow of hot air can be better guided. On this basis, compared with the vertical and horizontal settings of the heat dissipating fins 2, the surface area of ​​the tilted heat dissipating fins 2 in this embodiment is larger, thereby improving the heat dissipation effect of the heat dissipating fins 2 to a certain extent.

[0051] In addition, the angle between the heat dissipating fin 2 and the vertical antenna 4 in this embodiment can be between 15 degrees and 60 degrees, specifically 15 degrees, 30 degrees, 45 degrees, 60 degrees, etc. In actual application, the inclination angle of the heat dissipating fin 2 can be selected based on the environment in which the jammer is used. If the environment in which the jammer works usually has a large wind speed, the angle between the heat dissipating fin 2 and the vertical antenna 4 can be 15 degrees; and if the wind speed in the environment in which the jammer works is usually relatively small, the angle between the heat dissipating fin 2 and the vertical antenna 4 can be 60 degrees. Of course, if the environment in which the jammer works is not fixed, the angle between the heat dissipating fin 2 and the antenna 4 can be selected to be 45 degrees.

[0052] Furthermore, in a specific implementation of this embodiment, the heat dissipating fin 2 can be a straight fin, and the height of each heat dissipating fin 2 can be 20mm~24mm, for example, it can be 20mm, 22mm, 24mm, etc., and the spacing between two adjacent heat dissipating fins 2 is 10mm~14mm, specifically 10mm, 11mm, 12mm, 13mm, 14mm.

[0053] like Figure 3 As shown, in another optional embodiment of the present application, the heat dissipation fin 2 can also be a wavy line fin.

[0054] It should be noted that the heat dissipating fin 2 in this embodiment can be a wavy line fin formed by smoothly transitioning and splicing multiple circular arc segments. The radius corresponding to each circular arc segment should be the same and cannot be too small. In addition, the central angle corresponding to each circular arc segment should not exceed 15 degrees; thereby, the overall fluctuation amplitude of the entire wavy line fin is not too large, thereby reducing the resistance of the airflow in the airflow channel between two adjacent heat dissipating fins 2 as much as possible, and avoiding the accumulation of rainwater, dust, etc. in the heat dissipating fin 2.

[0055] Based on the above discussion, in order to further enhance the heat dissipation effect of the heat dissipating fins 2 on the various power amplifier modules 5 inside the box 1, in this embodiment, a heat dissipating fan 3 is further provided on the side of the box 1 where the heat dissipating fins 2 are provided, spaced relative to the heat dissipating fins 2. The heat dissipating fan 3 is used to enhance the airflow in the environment where the heat dissipating fins 2 are located, thereby enhancing the heat dissipation effect of the heat dissipating fins 2. It is understandable that the heat dissipating fan 3 in this embodiment should be provided directly facing the surface of the box 1 where the heat dissipating fins 2 are located, and can blow air into the space between the heat dissipating fins 2 and the heat dissipating fan 3, thereby driving the heat dissipating airflow toward the edge of the heat dissipating fins 2, or can exhaust air to form a negative pressure in the space between the heat dissipating fins 2 and the heat dissipating fan 3, so that the hot air flows toward the side of the heat dissipating fan 3, and the cold air flows from the edge of the heat dissipating fins 2 toward the heat dissipating fins 2.

[0056] In addition, as described above, in this embodiment, heat dissipation fins 2 are provided on the side surfaces on opposite sides of the box body 1. Thus, the heat dissipation fan 3 can be provided on one side of the box body 1, for example, it can be provided on the outside of the side where the power amplifier module 5 in the box body 1 is located, that is, to dissipate heat from the heat dissipation fins 2 that can directly conduct heat with the power amplifier module 5; of course, the heat dissipation fins 2 can also be provided on opposite sides of the box body 1, and the heat dissipation fins 2 on opposite sides of the box body 1 can be dissipated at the same time, thereby improving the heat dissipation effect. No specific restrictions are made in this application.

[0057] In order to further improve the heat dissipation effect of the cooling fan 3 on the cooling fins 2, in an optional embodiment of the present application, the cooling fan 3 in the interference device is used to extract air from the space between the cooling fins 2 and the cooling fan 3;

[0058] Correspondingly, the width of the heat dissipation fin 2 gradually increases from the side close to the box body 1 to the side away from the box body 1; and / or, the two side surfaces of the heat dissipation fin 2 are respectively a convex curved side surface and a flat side surface, so that an air flow channel with a wide middle and narrow ends is formed between two adjacent heat dissipation fins 2.

[0059] like Figure 4 As shown, Figure 4 The schematic diagram of the cross section of part of the heat dissipation fin 2 is shown. The side surfaces of each heat dissipation fin 2 can be all curved surfaces, and the width of each heat dissipation fin 2 gradually decreases from the direction of being close to the surface of the box 1 to the direction away from the surface of the box 1. As a result, the width of the air flow channel between adjacent heat dissipation fins 2 gradually decreases from the direction of being close to the surface of the box 1 to the direction away from the surface of the box 1. When the heat dissipation fan 3 exhausts the environment where the heat dissipation fin 2 is located, as shown in FIG. Figure 4As shown by the dotted line with an arrow in the middle, the air flow flows from the surface of the box 1 to the direction away from the box 1, and the width of the air flow channel gradually decreases from the surface of the box 1 to the direction away from the surface of the box 1, which can accelerate the hot air flow in the air flow channel to flow to the side of the cooling fan 3, thereby further improving the heat dissipation speed of the cooling fins 2.

[0060] like Figure 5 As shown, Figure 5 Schematic diagram of the relative position relationship between two adjacent heat fins 2. In actual application, the heat dissipation fan 3 is generally closer to the middle position of each heat dissipation fin 2. That is to say, when the heat dissipation fan 3 extracts air from the heat dissipation fin 2, it will drive the hot air in the air flow channel between the two adjacent heat dissipation fins 2 to flow from the two ends of the air flow channel to the two ends of the air flow channel, that is, Figure 5 As shown by the dotted line with an arrow in the middle, the air flow channel formed between two adjacent heat dissipation fins 2 is narrow in the middle and wide at both ends, which can accelerate the air flow velocity to the middle area of ​​the air flow channel, thereby increasing the flow velocity of the hot air flow, that is, increasing the heat dissipation speed of the heat dissipation fins 2.

[0061] Based on the above discussion, refer to Figure 1 and Figure 6 In another optional embodiment of the present application, the box 1 in the interference device may further include a first shell 11 and a second shell 12; the heat dissipation fins 2 are at least provided on the outer surface of the first shell 11; and the heat dissipation fan 3 is suspended on the outer side of one side of the first shell 11 in the box 1 through a support frame;

[0062] The power amplifier module 5 is arranged on the inner surface of the first housing 11;

[0063] A plurality of cooling fans 3 are symmetrically arranged around the center of the first housing 11 , and the planes where the cooling fans 3 are located and the planes where the cooling fins 2 are located are parallel to each other.

[0064] As described above, the box body 1 in the present application includes a first shell 11 and a second shell 12 that can be opened and closed with respect to each other, wherein the main control module and the detection module are jointly arranged on the inner surface of the second shell 12, and each power amplifier module 5 is arranged on the inner surface of the first shell 11. During the actual operation of the jamming device, the heat generated by the power amplifier module 5 during actual operation is often relatively high. For this reason, in this embodiment, the cooling fan 3 is arranged near the outer side surface of the first shell 11, that is, the cooling fan 3 preferentially dissipates heat from the first shell 11 where the power amplifier module 5 is located, thereby more efficiently ensuring that the temperature of each power amplifier module 5 in the box body 1 is not too high, thereby ensuring the reliability of the operation of the entire device.

[0065] Based on the above discussion, in an optional embodiment of the present application, a plurality of power amplifier modules 5 may be detachably provided in the box 1 of the interference module;

[0066] The power amplifier module (5) includes modules for outputting interference signals of eight different frequency bands, namely, 0.4G, 0.8G, 0.9G, 1.2G, 1.5G, 2.4G, 5.2G and 5.8G.

[0067] In order to interfere with drone signals of multiple frequency bands in this embodiment, multiple power amplifier modules corresponding to different frequency bands are comprehensively set up. Each power amplifier module 5 outputs an interference signal of one frequency band, thereby achieving interference with more drones with different signals.

[0068] In addition, in order to further enhance the flexibility of the use of the interference device in the present application, each power amplifier module 5 can be installed on the inner surface of the box 1 in a detachable connection manner. Thus, during use, the power amplifier modules 5 at various positions can be replaced at any time according to actual application requirements, which facilitates the maintenance of the power amplifier modules 5 or the replacement of power amplifier modules 5 with new frequency bands, bringing convenience to users.

[0069] To sum up, in the present application, heat dissipation fins are arranged on the outer surface of the box. On the basis of heat conduction and heat dissipation of the functional modules arranged in the box through the heat dissipation fins, the heat dissipation fins arranged on the outside of the box are also arranged as inclined strip fins. On the one hand, the inclined strip fins can better guide and dissipate the hot air flow. On the other hand, the inclined strip fins have a larger surface area on the surface of the entire box, which can improve the heat dissipation effect of the heat dissipation fins on the various functional modules inside the box to a certain extent, thereby avoiding the problem of modules such as power amplifier modules being affected by excessive temperature and affecting the working performance to a certain extent, thereby ensuring the reliability of the interference device.

[0070] The present application also provides an embodiment of a detection and administration integrated device, which may include:

[0071] The jamming device as described in any of the above items, and the main control module and detection module built into the box 1 of the jamming device;

[0072] The antenna 4 in the interference device includes a detection antenna connected to the detection module and an interference antenna connected to the power amplifier module 5 .
