[0007] Furthermore, the screw motor is fixedly connected to the screw, the screw is threadedly connected to the slider, the slider is slidably connected to the slide rod and the slide rail, and the slider is fixedly connected to the moving seat.

[0008] By adopting the above technical solution, when the screw motor is started, it drives the screw fixedly connected to it to rotate, and the slider drives the moving seats on both sides to move simultaneously with the assistance of the slide rail and the slide rod.

[0009] Furthermore, the servo motor is fixedly connected to the rotating shaft, the rotating shaft is fixedly connected to the turntable, the turntable is fixedly connected to the crossbar, the crossbar is rotatably connected to the cleaning sleeve, and the turntable is rotatably connected to the connecting shaft.

[0010] By adopting the above technical solution, when the servo motor is started, it drives the rotating shaft and the turntable fixedly connected thereto to rotate, thereby replacing the cleaning sleeve and ensuring that the cleaning mechanism always maintains a good cleaning force.

[0011] Furthermore, a plurality of the cross bars and cleaning sleeves are provided, and the plurality of cross bars and cleaning sleeves are distributed in a circular pattern.

[0012] By adopting the above technical solution, multiple circumferentially distributed cleaning covers can provide a long-term cleaning effect on the camera during the entire safety inspection process of the drone body.

[0013] Furthermore, the cleaning sleeve is made of washable adhesive silicone material.

[0014] By adopting the above technical solution, the cleaning cover is made of washable sticky silicone material, which not only provides a good cleaning effect but also facilitates maintenance and reuse of the cleaning cover.

[0015] Furthermore, the drone body is fixedly connected to the connecting seat, and the connecting seat is rotatably connected to the camera.

[0016] By adopting the above technical solution, the fixed connection between the drone body and the connecting base, and the rotational connection between the connecting base and the camera, provide stability for the drone during flight, and also facilitate maintenance and adjustment of the camera.

[0017] Furthermore, there are two turntables, which are symmetrically arranged, and an arc-shaped plate is arranged on the outer side between the two turntables.

[0018] By adopting the above technical solution, the two symmetrically arranged turntables can provide symmetrical supporting forces for the crossbar, ensuring the balance of the cleaning process.

[0019] Furthermore, the arc-shaped plate is located outside the cleaning sleeve and does not contact the cleaning sleeve, and the arc-shaped plate is rotatably connected to the turntable.

[0020] By adopting the above technical solution, the position of the arc plate ensures that the cleaning sleeve will not adhere to the arc plate, thereby ensuring that the cleaning sleeve will not be obstructed by the arc plate when it rotates and is replaced as the servo motor is started.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The utility model is provided with a slider, a movable seat, a turntable and a cleaning cover. When the camera is contaminated, a cleaning cover with a sticky cleaning function can be used to clean it. During cleaning, the slider drives the movable seat to move, so that it rolls on the surface of the camera. During the rolling process, the dust and impurities adhered to the surface of the camera are adhered to ensure the cleanliness of the camera, thereby ensuring that the picture is presented more clearly. When the cleaning ability of one of the cleaning covers decreases, the cleaning cover can be replaced by the rotation of the turntable.

[0027] 2. The utility model provides an arc-shaped plate, a storage rack and a groove. When the drone body is undergoing normal safety inspection and the cleaning mechanism does not need to be activated, the arc-shaped plate and the groove on the storage rack can be used to store the cleaning cover on the turntable and wrap most parts. This prevents the cleaning cover from excessively adhering to dust during flight instead of having a cleaning function, which would cause a rapid decrease in cleaning ability.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Example 1:

[0038] An open-pit mine safety inspection and monitoring drone, such as Figures 1-6 As shown, it includes a drone body 1, a connecting seat 2, a camera 3 and a propeller 5. A camera 4 is provided on the front side of the camera 3. A cleaning mechanism 6 is provided on the front side of the camera 4. The cleaning mechanism 6 includes a screw motor 601, a slide rail 603, a slide rod 604, a servo motor 607 and a connecting shaft 612. A screw 602 is provided at the output end of the screw motor 601. A slider 605 is provided on the screw 602 and the slide rod 604. A moving seat 606 is provided on the slider 605. A rotating shaft 608 is provided at the output end of the servo motor 607. A turntable 609 is provided on the outside of the rotating shaft 608, a cross bar 610 is provided on the turntable 609, and a cleaning sleeve 611 is provided on the outside of the cross bar 610. The setting of the cleaning mechanism 6 enables the drone body 1 to effectively remove dust and impurities on the camera 4, ensure the clarity of the monitoring picture, and improve the accuracy of safety inspections. The coordinated work of the screw motor 601, the slide rail 603, the slide bar 604, the servo motor 607 and the connecting shaft 612 provides precise control of the cleaning mechanism 6, making the cleaning process more efficient and reliable.

[0039] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The screw motor 601 is fixedly connected to the screw rod 602, the screw rod 602 is threadedly connected to the slider 605, the slider 605 is slidingly connected to the slide rod 604 and the slide rail 603, and the slider 605 is fixedly connected to the moving seat 606. When the screw motor 601 is started, it drives the screw rod 602 fixedly connected to it to rotate, and the slider 605, with the assistance of the slide rail 603 and the slide rod 604, drives the moving seats 606 on both sides to move at the same time, ensuring the precise movement of the screw rod 602 on the slider 605, improving the stability and cleaning effect of the cleaning mechanism 6, and enabling the cleaning mechanism 6 to move flexibly on the surface of the camera 4 to achieve comprehensive cleaning.

[0040] See Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The servo motor 607 is fixedly connected to the rotating shaft 608, the rotating shaft 608 is fixedly connected to the turntable 609, the turntable 609 is fixedly connected to the cross bar 610, the cross bar 610 is rotatably connected to the cleaning sleeve 611, and the turntable 609 is rotatably connected to the connecting shaft 612. When the servo motor 607 is started, it drives the rotating shaft 608 and the turntable 609 fixedly connected thereto to rotate, thereby replacing the cleaning sleeve 611 to ensure that the cleaning mechanism 6 always maintains a good cleaning force. The rotatable connection between the cross bar 610 and the cleaning sleeve 611 enables the cleaning sleeve 611 to rotate along the cross bar 610 when cleaning the dust on the surface of the camera 4 through viscosity, ensuring that multiple sides of the cleaning sleeve 611 participate in the cleaning process.

[0041] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 There are multiple cross bars 610 and cleaning covers 611, and the multiple cross bars 610 and cleaning covers 611 are distributed in a circular pattern. The multiple circumferentially distributed cleaning covers 611 can provide a long-term cleaning effect on the camera 4 during the entire safety inspection process of the drone body 1. When the cleaning power of one of the cleaning covers 611 decreases, other cleaning covers 611 can be replaced and continued to be used.

[0042] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6The cleaning cover 611 is made of washable sticky silicone material, which not only provides a good cleaning effect, but also facilitates the maintenance and reuse of the cleaning cover 611, reducing the cost of use. At the same time, the cleaning cover 611 made of sticky silicone material can effectively absorb dust and impurities to keep the camera 4 clean.

[0043] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 The drone body 1 is fixedly connected to the connecting base 2, and the connecting base 2 is rotatably connected to the camera 3. The fixed connection between the drone body 1 and the connecting base 2, and the rotatable connection between the connecting base 2 and the camera 3, provide stability of the drone during flight, and also facilitate maintenance and adjustment of the camera 3. The design of the rotatable connection allows the camera 3 to adjust the shooting angle as needed, which increases the flexibility and adaptability of the drone body 1.

[0044] Example 2:

[0045] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 There are two turntables 609, and the two turntables 609 are symmetrically arranged. An arc-shaped plate 7 is arranged on the outer side between the two turntables 609. The two symmetrically arranged turntables 609 can provide symmetrical support force for the crossbar 610, ensuring the balance of the cleaning process. The setting of the arc-shaped plate 7 can cooperate with the groove 9 of the rack 8. During the safety inspection of the drone body 1, most of the positions of the cleaning cover 611 are protected to a great extent, and are not adhered to by dust and impurities in the air and lose their cleaning power.

[0046] See Figure 5 、 Figure 6 The curved plate 7 is located on the outside of the cleaning sleeve 611, and the curved plate 7 does not contact the cleaning sleeve 611. The curved plate 7 is rotatably connected to the turntable 609. The position of the curved plate 7 ensures that the cleaning sleeve 611 will not adhere to the curved plate 7, thereby ensuring that the cleaning sleeve 611 will not be obstructed by the curved plate 7 when it rotates and is replaced with the start of the servo motor 607. The rotatable connection design between the curved plate 7 and the turntable 609 ensures that when the turntable 609 switches the working cleaning sleeve 611 under the action of the servo motor 607, the curved plate 7 will not rotate, thereby avoiding affecting the cleaning operation of the cleaning sleeve 611.

[0047] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6A shelf 8 is provided on one side of the camera 3, and a groove 9 is provided on the shelf 8. The shelf 8 and the groove 9 provided thereon provide a storage space for the cleaning mechanism 6, so that the cleaning mechanism can be neatly stored when not in use. When the cleaning mechanism 6 is in the storage state, the groove 9 of the shelf 8 cooperates with the arc-shaped plate 7 and the turntable 609 to wrap most of all the cleaning covers 611, thereby reducing the amount of impurities and dust in the air adhering to the cleaning covers 611 during the flight of the drone body 1.

[0048] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The shelf 8 is fixedly connected to the camera 3, and the groove 9 is adapted to the turntable 609. The fixed connection between the shelf 8 and the camera 3 ensures the stability of the cleaning mechanism 6 on the drone body 1, and also ensures that the cleaning mechanism 6 is always adapted to the adjustment process of the camera 3. The high adaptability of the groove 9 and the turntable 609 enables the cleaning mechanism 6 to be accurately stored in the groove 9, thereby improving the neatness of the storage and the protection of the cleaning cover 611.

[0049] The implementation principle of the present utility model is as follows: first, when the drone body 1 is performing the safety inspection task normally, the cleaning mechanism 6 is in the retracted state. At this time, the turntable 609 is just stuck in the groove 9 of the rack 8, and a small part of the bottom of one of the cleaning covers 611 for cleaning is not completely wrapped; when the picture collected and output by the camera 4 is not clear, it means that a lot of impurities have adhered to the surface of the camera 4 and it needs to be cleaned. At this time, the cleaning mechanism 6 is started, and when the screw motor 601 is started, it drives the screw 602 to rotate. With the assistance of the slide rail 603 and the slide rod 604, the two sliders 605 drive the moving seats 606 on both sides to move at the same time, and the turntable 609 drives the arc plate 7 and the cleaning cover 611 away from the groove 9 of the rack 8 and close to the surface of the camera 4. When the cleaning cover 611 contacts the surface of the camera 4, under the dragging action of the moving seat 606, the cleaning cover 611 removes impurities and dust from the camera 4 during the continuous rolling process. When the cleaning cover 611 moves to the bottom of the camera 4, the cleaning cover 611 continues to clean the surface of the camera 4 in the reverse direction under the continuous action of the screw motor 601 and the screw rod 602 to ensure the cleaning effect until the turntable 609, the cleaning cover 611 and the curved plate 7 return to the groove 9 of the rack 8, and the drone body 1 continues to perform the safety inspection task; when cleaning is needed again during the execution process, the above steps are repeated. If it is found that the cleaning ability of the cleaning cover 611 used for cleaning is reduced, the servo motor 607 is started to drive the rotating shaft 608 and the turntable 609 to rotate. Since the curved plate 7 and the turntable 609 are rotatably connected, the curved plate 7 remains stationary, and the cross bar 610 and the cleaning cover 611 fixed on the turntable 609 rotate accordingly. After rotating 90 degrees, the servo motor 607 stops working. At this time, the cleaning cover 611 that has not been used is replaced to the cleaning operation position, and the cleaning process is repeated to continue cleaning the camera 4.
