DETAILED DESCRIPTION

[0025] This embodiment provides a technical solution:

[0026] like Figures 1 to 6 As shown, a UV imager based on full solar blind technology includes a fuselage body and a fixing device for fixing the fuselage body, wherein the fixing device includes a tail side panel 1, a rotating connecting rod 22, a rotating fixing rod 41, a front side panel 42, a tail fixing plate 51 for placing the tail end of the fuselage body, a front fixing plate 36 for fixing the front end of the fuselage body, and angle adjustment mechanisms for adjusting the angles of the tail fixing plate 51 and the front fixing plate 36. There are two tail side panels 1, and both ends of the rotating connecting rod 22 are respectively rotatably connected to the tail side panels 1. The tail fixing plate 51 is slidably connected to the tail side panel 1 under the transmission of the rotating connecting rod 22, and the rotating connecting rod 22 is rotated after being driven by the angle adjustment mechanism. One end of the rotating fixing rod 41 is rotatably connected to the rotating connecting rod 22, and the other end is fixed to the front side panel 42. The number of the rotating fixing rod 41 corresponds to that of the front side panels 42. There are two front side panels 42, and the front fixing plate 36 is slidably connected to the front side panel 42 under the drive of the angle adjustment mechanism.

[0027] like Figure 2 As shown, the fixing device also includes a "U"-shaped connecting rod 21 and a first sliding block 210. The two free ends of the "U"-shaped connecting rod 21 are respectively fixed to one end of the rotating connecting rod 22 and the first sliding block 210. The end of the first sliding block 210 facing away from the "U"-shaped connecting rod 21 is fixed to the side end of the tail fixing plate 51. The tail side plate 1 is provided with a sliding groove adapted to the sliding of the first sliding block 210, and the sliding groove is arc-shaped. When the rotating connecting rod 22 rotates, it can drive the "U"-shaped connecting rod 21 to rotate, thereby causing the tail fixing plate 51 to move. The moving path is the same as the sliding groove, which can be used to adjust the angle of the tail end of the fuselage body.

[0028] like Figure 2 and Figure 3As shown, the angle adjustment mechanism includes a first drive motor 253, a driving wheel 254, a first driven wheel 23, a first synchronous transmission belt 24, a second synchronous transmission belt 26, a second driven wheel 27, a third driven wheel, a third synchronous transmission belt 28, an "L"-shaped connecting rod 38, a sliding connecting rod 33 and a connecting rod 34; the output end of the first drive motor 253 is fixed to the driving wheel 254, the driving wheel 254 and the first driven wheel 23 are meshed for transmission, and are tightened by the first synchronous transmission belt 24, and the first driven wheel 23 is connected to the rotating wheel 23.

Correspondingly, the front side plate 42 is provided with an arc groove 43. The first driving motor 253 can drive the driving wheel 254 to rotate. Since the driving wheel 254 and the first driven wheel 23 are synchronously tightened by the first synchronous transmission belt 24, the first driven wheel 23 will also rotate, and at the same time drive the rotating connecting rod 22 to rotate. The driving wheel 254 and the second driven wheel 27 are synchronously driven by the second synchronous transmission belt 26, and the second driven wheel 27 and the third driven wheel are synchronously driven by the third synchronous transmission belt 28, so the angular rotation between the front fixing plate and the tail fixing plate 51 can be synchronized, which is more conducive to the balance of the fuselage body.

[0029] like Figure 2 As shown, the angle adjustment mechanism further includes a connecting shaft 25 , one end of which is fixed to the output end of the first driving motor 253 , and the other end of which is fixed to the middle of the driving wheel 254 .

[0030] In this embodiment, the side end of the driving wheel 254 is provided with a first annular groove, the side end of the first driven wheel 23 is provided with a second annular groove, and the first synchronous transmission belt 24 is respectively fitted with the groove walls of the first annular groove and the second annular groove.

[0032] In order to make the end of the connecting rod 34 slide better, an arc-shaped sliding block 330 sliding in the arc-shaped groove is provided at the end of the connecting rod 34 .

[0033] like Figure 4 and Figure 6As shown, the third driven wheel is provided with an inner diameter adjustment assembly for adjusting the inner diameter, and the inner diameter adjustment assembly includes a fixed inner wheel 32, a sliding column 29, a first elastic member 30, an arc-shaped carrier plate 31, an inner diameter adjustment column 39, a rotating rod 391 and a fixed insert 392; the annular side end of the fixed inner wheel 32 is provided with a receiving groove and a sliding rod groove adapted to the sliding of the sliding column 29, and the middle part of the fixed inner wheel 32 is provided with an adjustment groove adapted to the sliding of the inner diameter adjustment column 39, the sliding rod groove and the receiving groove are correspondingly arranged, and the sliding rod groove and the adjustment groove are connected; one end of the sliding column 29 is slidably arranged in the sliding rod groove, and the other end is connected to the arc The bottom end of the arc-shaped carrier plate 31 is fixed; the first elastic member 30 is sleeved on the outside of the sliding column 29, and one end of the first elastic member 30 is fixed to the bottom of the accommodating groove, and the other end is tightly pressed against the bottom end of the arc-shaped carrier plate 31; one end of the inner diameter adjusting column 39 slides in the adjusting groove, and the other end is fixed to the rotating rod 391, and the end of the rotating rod 391 facing away from the inner diameter adjusting column 39 is fixed to the inner bottom end of the fixed insert 392, and the end of the fixed inner wheel 32 is provided with a fixed thread groove, and accordingly, the end of the fixed insert 392 facing the fixed inner wheel 32 is provided with a thread section adapted to the fixed thread groove.

[0034] When the inner diameter of the third driven wheel increases, it means that its rotation speed is slowed down, so the front end of the fuselage body can rotate at a smaller angle than the rear end of the fuselage body. On the contrary, when the inner diameter of the third driven wheel decreases, it means that its rotation speed is increased, so the front end of the fuselage body can rotate at a larger angle than the rear end of the fuselage body. The technician can rotate the fixed insert 392 according to actual needs to adjust the depth of the inner diameter adjustment column 39 in the adjustment groove. It can then be used to adjust the sliding of the slide column 29 to achieve the adjustment of the inner diameter of the third driven wheel.

[0035] In this embodiment, the inner diameter adjustment column 39 is in a truncated cone shape, and one end of the sliding column 29 facing away from the arc-shaped carrier plate 31 is in tight contact with the side end of the inner diameter adjustment column 39 .

[0036] like Figure 2 As shown, the upper end of the tail fixing plate 51 is provided with a fixing member for clamping the fuselage body, and the fixing member is correspondingly arranged at both ends of the tail fixing plate 51, and the fixing member includes a fixing block 510, a clamping block 53 and a second elastic member 52, the fixing block 510 is fixed to the upper end of the tail fixing plate 51, one end of the second elastic member 52 is fixed to the inner side of the fixing block 510, and the other end is fixed to the side end of the clamping block 53, and the fuselage body fixing clamp is arranged between the two clamping blocks 53.
