Description

Technical Field

[0001] This utility model belongs to the field of navigation and communication technology, and specifically relates to a direction finding system for navigation interference detection. Background Technology

[0002] With the rapid development of satellite navigation jamming technology, satellite navigation signals have problems such as weak strength, open signal modulation methods, and predictable navigation data, making navigation systems generally very vulnerable and easily interfered with by virtual signals. Therefore, the importance of resisting satellite navigation jamming is increasing. Interference detection is a key system for navigation, control, and direction finding in the process of resisting satellite navigation jamming. Among them, the direction finding system for interference detection is used to detect the signal in the direction the antenna is pointing.

[0003] Chinese patent CN222529498U discloses a direction-finding system for navigation interference detection. By integrating the receiver, compass, duplexer, power supply, and switch into a housing, the size of the housing can be reduced, thereby improving the portability of the system. The housing and cover are detachable, so when the direction-finding system malfunctions, the cover can be removed to repair the receiver, compass, duplexer, power supply, and switch inside the housing, making the repair process faster and more convenient. However, this direction-finding system relies solely on a fan for heat dissipation, which is ineffective. Under long-term operation or high-temperature environments, this heat dissipation problem will affect the stability and service life of the system. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figures 1 to 4 As shown, a direction-finding system for navigation interference detection includes:

[0029] Digital receiver 1;

[0030] A heat dissipation mechanism 2 is installed between the top and bottom of the digital receiver 1. A support frame 3 is installed between the four corners of the bottom of the heat dissipation mechanism 2. An installation mechanism 4 is installed between the inner walls on both sides of the support frame 3.

[0031] The heat dissipation mechanism 2 includes a storage box 21, a circulation mechanism 22, a heat sink 23, a heat dissipation channel 24, and a semiconductor cooling chip 25. The storage box 21 is installed at the top of the support frame 3. The circulation mechanism 22 is installed between the two ends of the storage box 21. Two heat sinks 23 are provided, and the two heat sinks 23 are respectively installed on the upper part of the outer surface and the lower part of the outer surface of the circulation mechanism 22. The opposite sides of the two heat sinks 23 are respectively installed at the top and bottom of the digital receiver 1. Multiple heat dissipation channels 24 are provided, and multiple heat dissipation channels 24 are respectively opened on the outer wall of the two heat sinks 23. The semiconductor cooling chip 25 is installed at the bottom of the storage box 21.

[0032] Depend on Figures 1 to 3 It can be seen that multiple directional receiving antennas 5 are installed on the upper part of both ends of the digital receiver 1, an interference signal monitoring module 6 is installed on the lower part of the outer wall of the heat dissipation mechanism 2, and a multi-element antenna array 7 is installed on the top of the heat dissipation mechanism 2.

[0033] The circulation mechanism 22 includes a circulation pump 221, an infusion pipe 222, a refrigeration pipe 223, and a return pipe 224. The circulation pump 221 is installed at the lower end of one end of the storage tank 21, the infusion pipe 222 is installed at the top of the circulation pump 221, there are two refrigeration pipes 223, and both refrigeration pipes 223 are installed on the outer surface of the infusion pipe 222. The return pipe 224 is installed at the other end of the two refrigeration pipes 223, and the other end of the return pipe 224 is installed at the upper end of the other end of the storage tank 21.

[0034] As shown above, in the direction-finding system for navigation interference detection, the digital receiver 1 is responsible for receiving and processing signals from the directional receiving antenna 5 and the multi-element antenna array 7. It extracts navigation information and monitors interference signals through digital analysis. The directional receiving antenna 5 enhances the reception capability of navigation signals in a specific direction, helping to determine the approximate direction of the interference signal. The interference signal monitoring module 6 monitors the interference components in the received signal in real time, identifies and separates the interference signal, and provides data support for subsequent interference processing. The multi-element antenna array 7, composed of multiple antenna elements, accurately determines the direction of arrival of the interference signal or navigation signal through spatial signal reception and array signal processing technology, improving direction-finding accuracy. These components work together to ensure the stable operation and efficient direction-finding capability of the navigation system in complex electromagnetic environments. During the operation of this direction-finding system, the heat generated by the digital receiver 1 is transferred to the two heat sinks 23 in contact with its top and bottom. At this time, the heat is dissipated through the multiple heat dissipation channels 24 on the heat sink 23. Initial cooling is performed to increase the heat dissipation area and improve cooling efficiency. At the same time, the circulation pump 221 and the thermoelectric cooler 25 also start working: the circulation pump 221 draws out the coolant from the storage tank 21 and delivers it to the two cooling pipes 223 through the liquid delivery pipe 222. The cooling pipes 223 are designed with a serpentine structure and are located inside the heat sink 23. When the coolant flows in the cooling pipes 223, it absorbs the heat transferred by the heat sink 23, thereby reducing the temperature of the heat sink 23 and dissipating heat for the digital receiver 1. The coolant that has absorbed heat returns to the storage tank 21 through the return pipe 224, forming a closed cooling cycle. At the same time, the thermoelectric cooler 25 cools the coolant in the storage tank 21 to ensure that the coolant always maintains a low temperature, thereby achieving a continuous cooling effect. This design further improves the cooling efficiency, reduces the operating temperature of the equipment, reduces the risk of performance degradation or equipment damage due to overheating, thereby extending the service life of the entire direction finding system and ensuring its stable operation in various high-temperature environments.

[0035] For details, please refer to Figures 1 to 3 As shown, the cooling pipe 223 is configured with a serpentine structure and is located inside the heat sink 23. The return pipe 224 is configured with a T-shaped structure and a valve is provided on the lower part of the outer surface of the return pipe 224.

[0036] As can be seen from the above, increasing the contact area between the cooling pipe 223 and the heat sink 23 allows the coolant to exchange heat more fully with the heat sink 23 during the flow process, thereby improving the heat dissipation efficiency and facilitating the injection of coolant into the storage tank 21 through the return pipe 224.

[0037] Example 2:

[0038] refer to Figure 4As shown, the mounting mechanism 4 includes a positive and negative screw 41, an adjusting handle 42, a mounting clamp 43, and a limiting groove 44. The positive and negative screw 41 is mounted between the inner walls of both sides of the support frame 3 via bearings. There are two adjusting handles 42 and two mounting clamps 43. The two adjusting handles 42 are respectively mounted at both ends of the positive and negative screw 41. The two mounting clamps 43 are respectively threaded onto both sides of the outer surface of the positive and negative screw 41. There are four limiting grooves 44, and the four limiting grooves 44 are respectively opened on the upper part of the outer walls of both sides of the two mounting clamps 43.

[0039] As can be seen from the above, when it is necessary to install or adjust the direction finding system, the user can rotate the adjusting handle 42 to drive the positive and negative screws 41 to rotate. At this time, the two mounting plates 43 will move relative to each other or in opposite directions under the rotation of the positive and negative screws 41. Specifically, when the user rotates the adjusting handle 42 in one direction, the two mounting plates 43 will move closer to each other, thereby clamping the object to be installed; while when the user rotates the adjusting handle 42 in the opposite direction, the two mounting plates 43 will move away from each other, thereby releasing the object to be installed. The user can easily adjust the installation by simply rotating the adjusting handle 42. The position of the clamping plates 43 allows for clamping or loosening operations, which greatly simplifies the installation process and improves installation efficiency. In addition, since two limiting grooves 44 are provided on each of the two mounting clamping plates 43, and these limiting grooves 44 are slidably connected to the wall of the support frame 3, the stability of the mounting clamping plates 43 during movement is ensured, effectively preventing offset or shaking, thereby ensuring the accuracy and reliability of the installation or adjustment process. This design not only adapts to the installation requirements of different equipment or platforms, but also improves the adaptability and flexibility of the system, providing strong support for the widespread application of the direction finding system.

[0040] Preferred, Reference Figure 4 As shown, multiple rubber particles are provided on the lower part of the opposite surfaces of the two mounting plates 43, and the limiting groove 44 is slidably connected to the wall of the support frame 3.

[0041] As can be seen from the above, the rubber particles can increase the friction between the mounting clamp 43 and the object being installed, making the installation more stable and preventing the object from loosening or shifting due to vibration or other reasons during system operation. This improves the installation stability and reliability of the entire direction finding system, keeps the mounting clamp 43 stable during movement, prevents the mounting clamp 43 from shifting or shaking during movement, and ensures the accuracy and stability of the installation.

[0042] Application example:

[0043] This design is suitable for high-temperature or enclosed working environments, such as the stable operation of military navigation equipment under extreme temperatures, the ability of outdoor communication base stations to withstand high environmental temperatures to reduce malfunctions, and the long-term stable operation of industrial monitoring equipment in enclosed factories. Its heat dissipation mechanism 2 achieves efficient circulation and cooling of coolant through the coordinated work of circulating pump 221, cooling pipe 223, return pipe 224, and semiconductor cooling chip 25, which quickly dissipates the heat generated by components such as digital receiver 1, keeping the equipment within the normal operating temperature range, thereby improving the stability and reliability of the system. The installation mechanism 4, through the ingenious design of positive and negative screws 41, adjusting handle 42, mounting clamp 43, and limiting groove 44, enables the direction finding system to be installed conveniently, quickly, and stably on various equipment or platforms, adapting to the installation needs of different environments and demonstrating its strong adaptability and flexibility.
