DETAILED DESCRIPTION

[0022] See also Figure 1-4 The utility model provides a radar signal processing device, comprising:

[0023] A control chamber 1 is provided with a turntable 2 rotatably disposed on the upper end of the control chamber 1, a mounting frame 3 is provided on the top of the turntable 2, a pot body 4 is buffered and mounted on the mounting frame 3, a signal receiver 5 is provided directly above the pot body 4, a plurality of support rods 6 are obliquely fixedly disposed on the circumference of the signal receiver 5, the support rods 6 are fixedly connected to the outer end of the mounting frame 3, a cleaning mechanism 8 is rotatably provided on the bottom of the inner arc surface of the pot body 4, for cleaning the surface of the pot body 4.

[0024] When in use, the control compartment 1 is first fixedly installed in the designated position, and then the turntable 2, the mounting frame 3, the pot body 4, the cleaning mechanism 8 and the signal receiver 5 are installed in sequence. Afterwards, the turntable 2 is rotated by the control compartment 1 to adjust the orientation of the device. When dust, dirt or other impurities accumulate on the surface of the pot body 4 due to long-term use, the cleaning mechanism 8 is rotated to regularly maintain and clean the surface of the pot body 4 to prevent dust, dirt, etc. from affecting the accuracy and stability of radar signal transmission.

[0025] In this embodiment, the mounting frame 3 includes: an inner ring frame 31, an outer ring frame 32 and a support plate 33. The inner ring frame 31 and the outer ring frame 32 are coaxially arranged annular structures, and the diameter of the inner ring frame 31 is smaller than that of the outer ring frame 32. A plurality of support plates 33 are arranged in a circular array and are not arranged between the inner ring frame 31 and the outer ring frame 32. The two sides of the support plate 33 are respectively connected to the outer wall of the inner ring frame 31 and the inner wall of the outer ring frame 32. The support plate 33 is an arc-shaped plate adapted to the shape of the pot body 4, and a buffer layer is provided on the side of the support plate 33 close to the pot body 4, and the outer convex surface of the pot body 4 is fixed on the support plate 33.

[0026] It should be explained that, by providing multiple support plates 33 and buffer layers, the pot body 4 is provided with buffer support at multiple locations, thereby preventing the vibration generated by the equipment during operation from being directly transmitted to the pot body 4 and having an adverse effect on the stability and precision of the pot body 4 .

[0027] In this embodiment, one side of the bottom of the mounting frame 3 is hinged to the turntable 2, and a telescopic rod 7 is provided on the side of the turntable 2 away from the hinged portion between the mounting frame 3 and the turntable 2, and both ends of the telescopic rod 7 are hinged to the mounting frame 3 and the turntable 2 respectively.

[0028] In this embodiment, the cleaning mechanism 8 includes: a rotating block 81 rotatably arranged at the bottom of the inner concave surface of the pot body 4, each of the support plates 33 is commonly connected to a mounting plate on one side close to the top of the outer convex surface of the pot body 4, a servo motor 82 is arranged on the mounting plate, and the output shaft of the servo motor 82 is fixedly connected to the rotating block 81, two groups of short shafts 83 are symmetrically fixed on the circumference of the rotating block 81, and a cleaning arc plate 84 is fixed on the outer end of each short shaft 83, a shovel plate 85 is arranged on the bottom of the cleaning arc plate 84 on the side of the cleaning direction, a flexible scraper strip is adhered to the bottom of the cleaning arc plate 84 away from the shovel plate 85, a cleaning cavity is opened on the inner side of the cleaning arc plate 84 along its extension direction, a waste outlet 841 is opened on the side of the cleaning arc plate 84 away from the short shaft 83, and the upper end of the shovel plate 85 and the waste outlet 841 are both connected to the cleaning cavity.

[0029] Specifically, the cleaning arc plate 84 is driven to rotate by the servo motor 82, and the shovel plate 85 contacts the inner arc surface of the pot body 4 to scrape and clean the dust on its surface. As the servo motor 82 rotates, the dust is collected in the cleaning cavity and discharged from the waste outlet 841. At the same time, the surface of the pot body 4 is further cleaned by the flexible scraper strip on the rear side to avoid stains and water marks on the surface of the pot body 4, thereby ensuring that the surface of the pot body 4 is clean.

[0030] In this embodiment, the cleaning arc plate 84 is located above the shovel plate 85 and is provided with a nozzle 86 downwardly. A plurality of nozzles 86 are evenly arranged along the extension direction of the cleaning arc plate 84. The nozzles 86 are respectively connected to an external water tank and an air source.

[0031] It should be explained that when cleaning the pot body 4, the nozzle 86 is first switched to be connected to the air source, and high-pressure gas is sprayed through the nozzle 86 to blow away the floating dust on the surface of the pot body 4. Then the nozzle 86 is switched to be connected to the water tank, and water is sprayed through the nozzle 86 to clean the surface of the pot body 4. By spraying air first and then water, the surface of the pot body 4 is cleaned layer by layer to improve the cleaning efficiency.

[0032] Preferably, the telescopic rod 7 can be extended to increase the inclination angle of the pot body 4, which is convenient for the falling of dust, dirt, etc. and improves the cleaning efficiency of the cleaning mechanism 8.

[0033] In this embodiment, the cleaning arc plate 84 is rotatably provided with a limiting wheel near the bottom of one end of the short shaft 83, and the limiting wheel near one end of the short shaft 83 is coaxially fixed with a cleaning brush 87, the cleaning brush 87 is extended along the cleaning cavity, and the other end of the cleaning brush 87 is rotatably provided on the cleaning arc plate 84.

[0034] It should be explained that the cleaning brush 87 is a flexible round-bristle brush. When cleaning the pot body 4, the limiting wheel rolls and drives the cleaning brush 87 to rotate, so that the dust shoveled into the cleaning cavity by the shovel plate 85 is shoveled out. At the same time, the cleaning brush 87 rotates and cleans the surface of the pot body 4. The shovel plate 85 and the cleaning brush 87 are used to scrape the solidified stains on the pot body 4 first and then brush them, thereby improving the cleaning effect.

[0035] In this embodiment, the pot body 4 is provided with a limiting groove 41 at the limiting wheel, and the limiting wheel is set in the limiting groove 41 for rolling limiting, so as to limit the cleaning arc plate 84 and ensure that it is always in contact with the pot body 4.

[0036] In this embodiment, the brush rod of the cleaning brush 87 is made of a flexible material, and the bristles of the cleaning brush 87 are spirally bonded to the outer peripheral side of the brush rod, so as to facilitate the removal of dust and other impurities in the cleaning cavity.

[0037] Optionally, the bristles may be replaced with a flexible scraper.

[0038] In this embodiment, a curved baffle 842 is provided on one side of the cleaning chamber close to the nozzle 86 to reduce the splashing of dust and other impurities when the cleaning brush 87 rotates.

[0039] During the specific implementation, the control cabin is first fixed in the designated position, and then each component is installed in turn. Afterwards, the direction and angle of the device are adjusted through the control cabin and the telescopic rod. When dust, dirt or other impurities accumulate on the surface of the pot due to long-term use, the cleaning mechanism is rotated to regularly maintain and clean the surface of the pot to prevent dust, dirt, etc. from affecting the accuracy and stability of radar signal transmission.

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
