[0063] Embodiment 2

[0064] In the second embodiment of the present utility model, the self-cleaning radar scanning system with a protective film of the present utility model includes a die-changing device, and the die-changing device can automatically replace the dusty protective film 3 on the surface of the probe 2. Figure 2Figure 2 is a schematic structural diagram of the second embodiment of a self-cleaning radar scanning system with a protective film 3 according to the present utility model. As Figure 2 shown, preferably, the film changing device in the present utility model includes a film output part 5, a film winding part 6, a passive reel 7 and an active reel 8. The passive reel 7 is disposed at the center of the film output part 5, and the active reel 8 is disposed at the center of the film winding part 6. The passive reel 7 and the active reel 8 are symmetrically arranged on both sides of the scanning radar main body 1. When the protective film 3 is not in use, the output part of the outermost circle of the protective film 3 on the passive reel 7 is fixedly connected to the axis of the active reel 8, and the protective film 3 wound on the passive reel 7 winds back from the surface where the probe 2 of the scanning radar main body 1 transmits and receives signals to the active reel 8.

[0065] Specifically, when the self-cleaning radar scanning system detects that the dust accumulation degree on the surface of the protective film 3 is greater than the set threshold, the active reel 8 starts to rotate and wind the dusty protective film 3 that is closely attached to the surface of the probe 2 at this time, or the film changing device works regularly, and the active reel 8 rotates regularly to wind the dusty protective film 3 that is closely attached to the surface of the probe 2 at this time, so as to keep the protective film 3 exposed on the surface of the probe 2 clean.

[0066] Specifically, the passive reel 7 is fixedly arranged on the scanning radar main body 1 through a first support member 9, and the active reel 8 is fixedly arranged on the scanning radar main body 1 through a second support member 10. The first support member 9 and the second support member 10 can be connected to the scanning radar main body by threads. Correspondingly, a connecting part is arranged on the scanning radar main body, and a screw hole is arranged on the connecting part.

[0067] In the present utility model, the movement of the protective film 3 on the surface of the probe 2 is realized by having the film output part 5 and the film winding part 6, so as to move the dirty protective film 3 with dust to the film winding part 6, and move the clean new protective film 3 to the surface of the probe 2 through the film output part 5, so as to ensure that the surface where the probe 2 transmits and receives signals is in a safe and clean environment, that is, to meet the safe environment for signal measurement, and will not be attenuated or severely attenuated due to dust and other environments.

[0068] In a further embodiment of the present utility model, a rotating handle is fixedly connected to the active reel 8, and the rotation of the active reel 8 is realized by rotating the rotating handle, thereby realizing the automatic replacement of the protective film 3.

[0069] In a further embodiment of the present utility model, the film changing device may include a driving device, and the driving device is used to drive the rotation of the active reel 8 to realize the automatic replacement of the protective film 3.

[0070] Specifically, the driving device includes a driving motor, an automatic controller and a gear structure. The output end of the driving motor is connected to a gear transmission mechanism. There are two mounting grooves provided on both sides of the gear structure, and the mounting grooves are used for fixedly mounting the active reel 8. The gear structure meshes with the gear transmission mechanism, and drives the active reel 8 to rotate through the meshing of the gears to realize automatic film changing; the automatic controller is connected to the driving motor, and the automatic controller is used to control whether the driving motor rotates according to whether the film changing is completed. The driving motor is used to drive the active reel 8 to rotate to realize automatic film changing.

[0071] Further, the driving device may further include a film changing switch button and an automatic film changing inductor. The film changing switch button, the automatic film changing inductor and the automatic controller are all connected. The film changing switch button is used to control whether the protective film 3 needs to be replaced, and the automatic film changing inductor is used to sense whether the film changing is completed.

[0072] Alternatively, in a further embodiment of the present invention, the film changing device may further include a timing module, which is communicatively connected to the driving device and is used to realize timed replacement of the protective film 3. Specifically, the timing module may be communicatively connected to the automatic controller, and the film winding part 6 is controlled to rotate regularly according to the timing information to realize timed automatic film changing.

[0073] In a further embodiment of the present invention, a dust-proof cover 11 is provided outside the film output part 5. By providing the dust-proof cover 11, the accumulation of dust on the protective film 3 can be reduced, especially for the clean protective film 3 placed on the film output part 5.

[0074] In a further embodiment of the present invention, the self-cleaning radar scanning system may further include a guiding part for limiting the protective film 3 so that it does not shift.

[0075] Specifically, the guiding part is provided at the edge position of the probe 2 and includes a limiting part (not shown in the figure), and the limiting part is used to limit the deviation of the protective film 3 during the moving process.

[0076] Specifically, guiding rollers 12 may be provided at the edge of the probe 2, and the guiding rollers 12 are used to guide the protective film 3 to move between the film output part 5 and the film winding part 6.

[0077] Since there is a certain distance for the protective film 3 to move from one side to the other side of the surface of the probe 2, in order to enable the protective film 3 to move smoothly and quickly during the moving process, by providing the guiding rollers 12 at the edge of the probe 2, the protective film 3 can be guided to move quickly, thereby improving the moving efficiency of the protective film 3.

[0078] In a further embodiment of the present utility model, an installation groove 13 may be provided at the edge of the probe 2. A part of the guiding roller 12 extends into the installation groove 13, and the installation groove 13 is provided at a position close to the film output part 5 and the film winding part 6.

[0079] In order to quickly and smoothly move the protective film 3 from the film output part 5 to the film winding part 6, the guiding roller 12 can be installed in the installation groove 13. The installation groove 13 can hide a part of the guiding roller 12, reducing the volume exposed on the outside. By virtue of the arc of the guiding roller 12, the protective film 3 can be quickly moved, and the angle of the protective film 3 moving at the edge of the probe 2 is also reduced, thus making the moving process smoother.

[0080] In a further embodiment of the present utility model, a limiting part 14 may be provided at the edge position of the probe 2, and the limiting part 14 is perpendicular to the guiding roller 12.

[0081] Since there is a certain distance for the protective film 3 to move from one side of the surface of the probe 2 to the other side, it may deviate during the moving process. Therefore, a limiting part 14 can be provided at the edge of the probe 2, and the limiting part 14 is perpendicular to the guiding roller 12. Thus, the protective film 3 can move quickly under the dual guidance and limitation of the guiding roller 12 and the limiting part 14, thereby greatly improving the film changing efficiency.

[0082] In a further embodiment of the present utility model, since the protective film 3 moves under the guidance of the guiding rollers 12 on both sides of the edge of the probe 2, there is a certain height between the protective film 3 and the surface of the probe 2 during the moving process. This height may cause some dust to enter the surface of the probe 2. Therefore, a movable pressing strip 15 can be provided on the limiting part 14 to limit the distance between the protective film 3 and the surface of the probe 2 through the movable pressing strip 15.

[0083] The above-mentioned movable pressing strip 15 can rotate axially on the limiting part 14. Since the protective film 3 on the film output part 5 needs to be replaced after use, at this time, the movable pressing strip 15 is rotated to the outside, and after the protective film 3 is replaced, the movable pressing strip 15 is rotated to one side of the protective film 3. By limiting the distance between the protective film 3 and the surface of the probe 2, the dust falling on the surface of the probe 2 can be minimized to the greatest extent.

[0084] Alternatively, the above-mentioned movable pressing strip 15 can be made of an elastic material to facilitate movement for replacing the protective film 3.

[0085] Embodiment III

The passive reel 7 is arranged at the center of the film output part 5, and the active reel 8 is arranged at the center of the film winding part 6. The passive reel 7 and the active reel 8 are symmetrically arranged on both sides of the scanning radar main body 1. When the protective film 3 is not in use, the output part of the outermost circle of the protective film 3 on the passive reel 7 is fixedly connected to the axis of the active reel 8, and the protective film 3 wound on the passive reel 7 winds back to the active reel 8 from the surface where the probe 2 of the scanning radar main body 1 transmits and receives signals.

[0087] Specifically, when the self-cleaning radar scanning system detects that the dust accumulation degree on the surface of the protective film 3 is greater than the set threshold, the active reel 8 starts to rotate and work, winding the dusty protective film 3 that is closely attached to the surface of the probe 2 at this time. Or, the film changing device works regularly, and the active reel 8 rotates and winds regularly the dusty protective film 3 that is closely attached to the surface of the probe 2 at this time, so as to keep the protective film 3 exposed on the surface of the probe 2 clean.

Through holes 19 are arranged on both vertical sides of the rectangular frame along the movement of the protective film 3, and the through holes 19 are used for passing through the protective film 3.

[0089] In this embodiment, by setting the movable parts 18 on the support frame 16, the support frame 16 can be installed on scanning radar main bodies 1 of different sizes and models. And, by setting the hollow part 17 on the support frame 16, the probe 2 can be directly exposed in the hollow part 17, so that certain sealing performance can be achieved without affecting the use of the scanning radar.

[0090] In order to apply probes 2 of various shapes with the greatest possibility and facilitate the smooth replacement of the protective film 3, the hollow part 17 of the support frame 16 is set as a rectangular frame. At the same time, through holes 19 are provided on both sides of the rectangular frame in the moving direction of the protective film 3, and a card slot is provided in the direction perpendicular to the moving direction of the protective film 3. By setting it like this, it can be ensured that only the signal transceiver area of the protective film 3 is exposed outside during the movement process. The protective film 3 is passed through one side through hole 19, wound around the surface of the probe 2 to the other side through hole 19, and finally wound back to the film winding part 6. In this way, it can meet the normal measurement signal of the scanning radar, and at the same time ensure that the surface of the probe is in a safe operating environment.

[0091] Among them, in this embodiment, the through holes 19 can realize the guiding function during the movement of the protective film 3, and at the same time can control the distance between the protective film 3 and the surface of the probe 2. At the same time, by setting a dust-proof strip in the card slot, it can prevent dust from entering the gap between the protective film 3 and the support frame 16.

[0092] In this embodiment, the film output part 5 and the film winding part 6 are used to realize the movement of the protective film 3 on the surface of the probe 2, so as to move the dirty protective film 3 with accumulated dust to the film winding part 6, and move the clean new protective film 3 to the surface of the probe 2 through the film output part 5, so as to ensure that the signal transceiver surface of the probe 2 is in a safe and clean environment, meet the signal measurement environment, and will not be attenuated or severely attenuated due to environmental factors such as dust.
