Description

Technical Field

[0001] This utility model relates to the field of dual-polarization radar transponder technology, and in particular to a dual-polarization Doppler weather radar transponder. Background Technology

[0002] A dual-polarization Doppler weather radar transponder is a high-precision standard signal source used for calibrating and verifying radar system performance. It receives a specific electromagnetic wave signal emitted by the radar and immediately transmits a standard echo signal with known intensity, phase, and polarization characteristics, providing the radar system with an absolutely accurate reference target. This process simultaneously calibrates the radar's transmit power, receiver sensitivity, range calibration, and, most critically, the amplitude and phase consistency of the dual polarization channels (horizontal and vertical polarization). By comparing the standard signal returned by the transponder with the radar's measured data, technicians can precisely quantify the radar's system bias, ensuring the accuracy of its measurements of precipitation particle shape, size distribution, and phase identification, thus providing reliable data quality assurance for weather forecasting, severe weather monitoring, and hydrological research.

[0003] In existing technologies, conventional dual-polarization radar transponders typically employ a fixed antenna design, with an unadjustable antenna deployment angle or a complex adjustment mechanism. This makes deployment in complex weather conditions in the field inconvenient and makes it difficult to quickly optimize the signal transmission and reception attitude to match the radar beam direction. Utility Model Content

[0004] The purpose of this invention is to provide a dual-polarization Doppler weather radar transponder to solve the above-mentioned problems. It improves upon the conventional dual-polarization radar transponder, which usually adopts a fixed antenna design, with an unadjustable antenna deployment angle or a complex adjustment mechanism. This makes it inconvenient to deploy in complex weather conditions in the field and makes it difficult to quickly optimize the signal transmission and reception attitude to match the radar beam direction.

[0006] Preferably, the driving assembly includes pulleys, a return spring, a groove block, and a sliding rod. Pulleys are slidably connected to both sides of the top surface of the trapezoidal block. A return spring is provided above the pulleys. The end of the return spring is fixedly connected to the bottom of the groove plate. A sliding rod is sleeved inside the return spring. The end of the sliding rod is fixedly connected to the groove block. The bottom of the return spring is fixedly connected to the surface of the sliding rod.

[0007] Preferably, hinges are threaded to both sides of the bottom wall of the groove plate, and a first antenna and a second antenna are respectively hinged to one side of each of the two hinges.

[0008] Preferably, an L-shaped guide rod is fixedly connected to one side of the first antenna, and the bottom of the L-shaped guide rod is slidably connected to the surface of the groove block.

[0009] Preferably, a connecting piece is threaded to the edge of the sliding groove surface, and a rain shield is fixedly connected to one side of the connecting piece.

Detailed Implementation

[0020] 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.

[0021] In practical implementation: such as Figures 1-4 As shown, a dual-polarization Doppler weather radar transponder includes a housing 1. The transponder body 2 is disposed inside the housing 1. A grooved plate 3 is disposed on the top of the housing 1. Square grooves are formed on both sides of the bottom wall of the grooved plate 3. A sliding groove is formed on one side of the housing 1. A pushing block 4 is slidably connected inside the sliding groove. A trapezoidal block 5 is fixedly connected to one side of the pushing block 4. A driving assembly 6 is disposed on the top surface of the trapezoidal block 5. The driving assembly 6 includes a pulley 61, a return spring 62, a grooved block 64, and a sliding rod 65. Pulleys 61 are slidably connected to both sides of the top surface of the trapezoidal block 5. A return spring 62 is provided above 61. The end of the return spring 62 is fixedly connected to the bottom of the groove plate 3. A sliding rod 65 is sleeved inside the return spring 62. The end of the sliding rod 65 is fixedly connected to a groove block 64. The bottom of the return spring 62 is fixedly connected to the surface of the sliding rod 65. Hinges are threadedly connected to both sides of the inner bottom wall of the groove plate 3. The first antenna 10 and the second antenna 11 are respectively hinged to one side of the two hinges. An L-shaped guide rod 12 is fixedly connected to one side of the first antenna 10. The bottom of the L-shaped guide rod 12 is slidably connected to the surface of the groove block 64.

[0022] In this embodiment: when the operator needs to use the transponder body 2, the operator can slowly slide the push block 4 to drive the trapezoidal block 5 to slide along the sliding groove. Then, when the trapezoidal block 5 moves to the side of the magnetic block 15, the magnetic block 15 can attract and fix the trapezoidal block 5. Then, the pulley 61 slides upward along the trapezoidal block 5, and then drives the sliding rod 65 to slide upward, so that the sliding rod 65 drives the groove block 64 to lift the L-shaped guide rod 12 upward, so that the L-shaped guide rod 12 lifts the first antenna 10 and the second antenna 11 upward and diagonally upward along the hinge, thereby effectively increasing the signal of the transponder body 2.

[0023] like Figures 1-4 As shown, a hinge is threaded to the edge of the top surface of the outer shell 1, and a top cover 7 is hinged to one side of the hinge. A groove is provided in the middle of the top surface of the top cover 7, and cleaning plates 8 are slidably connected to both sides of the inner side wall of the groove. Flexible cleaning cotton 9 is provided at the bottom of the cleaning plate 8.

[0024] In this embodiment: with the top cover 7, cleaning plate 8 and flexible cleaning cotton 9, when personnel need to clean foreign objects from the surface of the first antenna 10 and the second antenna 11, they can repeatedly push the cleaning plate 8 to drive the flexible cleaning cotton 9 to wipe the first antenna 10 and the second antenna 11, thereby facilitating the cleaning of foreign objects from the surface of the first antenna 10 and the second antenna 11 by the operators, thus playing the role of facilitating the cleaning of the first antenna 10 and the second antenna 11.

[0025] like Figures 1-4 As shown, a connecting piece is threaded to the edge of the sliding groove surface, and a rain shield 13 is fixedly connected to one side of the connecting piece.

[0026] In this embodiment, through the design of the rain shield 13 and the sliding groove, the rain shield 13 can effectively isolate rainwater outside the sliding groove during the use of the outer casing 1, thereby improving the waterproofness of the outer casing 1.

[0027] like Figures 1-4 As shown, a maintenance plate 14 is threadedly connected to the center of the front of the housing 1, and a wiring groove is provided on the surface of the maintenance plate 14.

[0028] In this embodiment, the maintenance plate 14 is provided to facilitate maintenance personnel to perform maintenance and repair on the transponder body 2 inside the outer casing 1.

[0029] like Figures 1-4 As shown, a magnetic block 15 is fixedly connected to one side of the sliding groove, and the magnetic block 15 and the trapezoidal block 5 are magnetically attracted to each other.

[0030] In this embodiment, the magnetic block 15 is provided to facilitate the operator in fixing the trapezoidal block 5.

[0031] In use, when calibrating the dual-polarization Doppler weather radar, the operator can move the outer casing 1 and the transponder body 2 to a suitable position. Then, the operator opens the top cover 7 and slides the push block 4 to move the trapezoidal block 5 along the sliding groove. One side of the trapezoidal block 5 is then magnetically attracted and fixed by the magnetic block 15. During the movement of the trapezoidal block 5, its pulley 61 slides upwards along the trapezoidal block 5. As the sliding rod 65 pushes upwards, it causes the return spring 62 to retract. Simultaneously, the sliding rod 65 drives the groove block 64, causing the L-shaped guide rod 12 to form a semi-fan shape, which respectively connects the first antenna 10 and the second antenna 11. The transponder body 2 is unfolded, which increases the signal received by the transponder body 2. After the operation is completed, the sliding push block 4 can be slid to release the trapezoidal block 5 from the magnetic block 15, so that the restrained return spring 62 is released from the restraint. Then the return spring 62 drives the sliding rod 65 to retract into the shell 1, so that the first antenna 10 and the second antenna 11 are hidden inside the groove plate 3, which makes it convenient for the operator to store the first antenna 10. Then the operator can close the top cover 7 and then repeatedly push the cleaning plate 8 to drive the flexible cleaning cotton 9 to continuously rub the surface of the first antenna 10 and the second antenna 11 to clean foreign objects, so as to keep the first antenna 10 from being contaminated.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
