Description

Technical Field

[0001] This utility model relates to the field of radar antenna cleaning technology, and more specifically to an automatic cleaning device for the surface of a radar antenna. Background Technology

[0002] The YLUKA1 millimeter-wave cloud measuring radar (referred to as "millimeter-wave cloud instrument") is a meteorological detection device operating in the Ka-band (35GHz±500MHz). By analyzing the scattering characteristics of electromagnetic waves by cloud particles, it can obtain parameters such as cloud height, structure, and vertical velocity in real time, with a detection range of up to 15 kilometers. It plays an important role in meteorological observation, air traffic control, and climate research. However, the upper surface of the radar antenna of the millimeter-wave cloud instrument is similar to a cone. During long-term operation, dust and impurities easily accumulate on its surface, which can affect the electromagnetic wave transmission and reception efficiency of the radar antenna. Currently, cleaning of the radar antenna surface is mostly done manually, but manual cleaning is time-consuming, labor-intensive, troublesome, and increases labor intensity, and needs improvement.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic cleaning device for the surface of a radar antenna involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: like Figure 1-5As shown, an automatic cleaning device for the surface of a radar antenna includes a radar antenna body 1. A cloud measuring instrument 9 is fixedly installed below the radar antenna body 1. A cleaning mechanism is provided above the radar antenna body 1. The cleaning mechanism includes a support base 2. An annular drain pipe 34 is fixedly installed below the support base 2. Multiple fan-shaped nozzles 35 are fixedly installed at the bottom of the annular drain pipe 34. A water tank 3 is fixedly installed on the right side of the top of the support base 2. The water tank 3 contains cleaning water. A water inlet 311 is opened on the top of the water tank 3. A tank cover 312 is threadedly connected to the upper part of the water inlet 311. A water pump 32 is fixedly installed on the right side of the top of the radar antenna body 1. The water pump 32 is located in front of the water tank 3. A first conduit 31 is fixedly installed at the water pump 32's suction end. One end is fixedly installed on the lower front of the water tank 3. An electromagnetic water valve is installed on the first conduit 31. The drain end of the water pump 32 is fixedly installed with the second conduit 33. One end of the second conduit 33 extends to the lower part of the support base 2 and is fixedly installed on the top of the annular drain pipe 34. One end of the second conduit 33 is connected to the inside of the annular drain pipe 34. The cleaning water in the water tank 3 is drawn out through the first conduit 31 by the water pump 32 and then transported to the inside of the annular drain pipe 34 by the second conduit 33. Finally, it is evenly sprayed on the surface of the radar antenna through multiple fan-shaped nozzles 35, which facilitates the cleaning of the surface of the radar antenna body 1. If it is necessary to add cleaning water to the inside of the water tank 3, simply unscrew the tank cover 312 and add an appropriate amount of cleaning water to the water tank 3 through the water inlet 311. The operation is simple and quick. A motor protective box 21 is fixedly installed on the top of the support base 2. A servo motor 22 and a worm gear reducer 23 are fixedly installed on the top of the inner wall of the motor protective box 21. The output end of the servo motor 22 is fixedly installed on the input end of the worm gear reducer 23 via a coupling. The output end of the worm gear reducer 23 is fixedly connected to a rotating rod 24 via a coupling. The outer wall of the rotating rod 24 is rotatably installed inside the support base 2 via bearings. A mounting base 25 is provided in the middle of the lower part of the support base 2. The bottom end of the rotating rod 24 is fixedly connected to the top of the mounting base 25. A cleaning scraper 26 is provided below the support base 2. The top end of the cleaning scraper 26 is fixedly installed on the bottom of the mounting base 25 via bolts. The inner wall of the cleaning scraper 26 overlaps the outer wall of the radar antenna body 1. The motor protective box 21 facilitates the cleaning of the servo motor 22 and the worm gear reducer 23. The worm gear reducer 23 provides protection, and the servo motor 22 drives the worm gear reducer 23 to operate, which in turn drives the rotating rod 24 to rotate. The rotating rod 24 then drives the mounting base 25 and the cleaning scraper 26 to rotate around the axis of the radar antenna body 1, so that the cleaning scraper 26 can effectively scrape off the dust and impurities remaining on the surface of the radar antenna. In conjunction with the cleaning water sprayed by the fan-shaped nozzle 35, a deep cleaning of the radar antenna surface is achieved, maintaining the cleanliness of the radar antenna surface. In this application, the cloud measuring instrument 9 is the YLU1 type Ka-band millimeter-wave cloud measuring instrument developed by Xi'an Huateng Microwave Company. It is a cloud observation device that detects cloud information by transmitting and receiving electromagnetic waves through the radar antenna body 1. Its normal operation requires a high degree of cleanliness of the radar antenna surface. The automatic cleaning function of this device can effectively ensure the stable operation of the cloud measuring instrument 9. Example 2: like Figure 1-5As shown, a support frame 4 is provided on the right side of the radar antenna body 1. A multi-stage electric telescopic rod 6 is fixedly installed on the upper right side of the support frame 4. A telescopic dust cover is provided on the multi-stage electric telescopic rod 6. The telescopic end of the multi-stage electric telescopic rod 6 extends to the left side of the support frame 4 and is fixedly connected to the middle of the right side of the support base 2. Two guide rods 7 are symmetrically fixedly connected to the right side of the support base 2. The outer walls of the two guide rods 7 are slidably connected to the inside of the support frame 4. A limit groove 5 is opened on the front of the support frame 4. A control panel 8 is fixedly installed on the upper front of the support frame 4. When it is necessary to clean the surface of the radar antenna, the multi-stage electric telescopic rod 6 is activated, so that its telescopic end drives the support base 2 and the entire cleaning mechanism to move towards the radar antenna body 1 until the cleaning scraper 26 contacts the surface of the radar antenna. At the same time, the guide rods 7 slide inside the support frame 4. To ensure the stability of the cleaning mechanism's movement and prevent deviation, after cleaning is completed, the multi-stage electric telescopic rod 6 is activated again, causing its telescopic end to retract, moving the cleaning mechanism away from the radar antenna body 1, and causing one end of the cleaning scraper 26 to rotate into the limiting groove 5, avoiding any impact on the normal operation of the radar antenna. In this application, the electromagnetic water valve, water pump 32, multi-stage electric telescopic rod 6, control panel 8, and other electrical equipment are all waterproof and can be used outdoors. They are all electrically connected to an external power supply and control system. The working status of each component can be controlled through the operation buttons or preset programs on the control panel 8, realizing the automation of the cleaning process. For example, a periodic cleaning mode can be set, and the cleaning program can be automatically started during the period when the radar antenna is not working, without manual intervention, which greatly improves cleaning efficiency and convenience.

[0021] In summary, as Figure 1-5 As shown, this automatic cleaning device for the surface of a radar antenna, when in use, allows the cleaning program to be set via the control panel 8, including parameters such as the extension distance of the multi-stage electric telescopic rod 6, the number of rotations of the servo motor 22, and the pumping time of the water pump 32. When the preset cleaning time is reached or a cleaning command is received, the water pump 32 starts, drawing cleaning water from the water tank 3 through the first conduit 31, delivering it to the annular drain pipe 34 through the second conduit 33, and then spraying it onto the surface of the radar antenna body 1 by multiple fan-shaped nozzles 35, thus cleaning its surface. During rinsing, the servo motor 22 drives the worm gear reducer 23 to rotate, causing the rotating rod 24, mounting base 25, and cleaning scraper 26 to rotate around the axis of the radar antenna body 1. The cleaning scraper 26 scrapes away dust and impurities from the surface of the radar antenna, working together with the sprayed cleaning water to achieve deep cleaning. After cleaning, the multi-stage electric telescopic rod 6 is activated, and its telescopic end retracts, causing the support base 2 and the entire cleaning mechanism to move away from the radar antenna body 1. One end of the cleaning scraper 26 rotates into the limiting groove 5 to avoid interfering with the normal operation of the radar antenna.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the connection position of valve components is provided with anti-leakage rubber strips, the outside of threaded rods or lead rods is provided with dustproof sleeves, and the equipment can be driven by either built-in batteries or external power supply. The control method is automatic control by a controller.
