Referring to fig. 1, a monitoring device provided in an embodiment of the present application includes a first housing 10, a camera 20, a transmission mechanism 30, and a cleaning mechanism 40.

The first housing 10 is provided with an accommodating space 11 therein, and the camera 20 is disposed in the accommodating space 11, and the camera 20 is configured to be rotatable about a first axis a with respect to the first housing 10. The transmission mechanism 30 is disposed in the accommodation space 11. The cleaning mechanism 40 includes a mounting shaft 41 and a cleaning assembly 42, the mounting shaft 41 is rotatably connected with the first housing 10 about the second axis b, and the mounting shaft 41 is drivingly connected with the camera 20 by means of the transmission mechanism 30, so that the mounting shaft 41 can be rotated by the camera 20, and the cleaning assembly 42 is connected to the mounting shaft 41.

In the monitoring device, the camera 20 is arranged in the accommodating space 11 by arranging the first shell 10 with the accommodating space 11, so that the first shell 10 can block pollutants for the camera 20. By arranging the camera 20 to be rotatable about the first axis a relative to the first housing 10, the camera 20 is enabled to take images in different orientations. By providing the transmission mechanism 30 in the accommodation space 11 and providing the cleaning mechanism 40 including the mounting shaft 41, the mounting shaft 41 is in transmission connection with the camera 20 by means of the transmission mechanism 30, so that the mounting shaft 41 can be driven by the camera 20 to rotate about the second axis b relative to the first housing 10. By providing the cleaning mechanism 40 further comprising a cleaning assembly 42 coupled to the mounting shaft 41, the cleaning mechanism 40 is enabled to rotate with the mounting shaft 41 relative to the first housing 10, enabling the cleaning mechanism 40 to clean contaminants from the first housing 10. When the camera 20 works, the camera 20 can drive the cleaning assembly 42 to rotate to clean the first shell 10, so that an additional driving piece is not needed to drive the cleaning mechanism 40, and the monitoring device has the advantages of reduced volume, simplified structure and reduced energy consumption.

It should be appreciated that the first housing 10 is made of a transparent material so that the camera 20 can clearly capture a clear image.

In some embodiments, as shown in fig. 1, the mounting shaft 41 is provided through the first housing 10. The cleaning assembly 42 includes a first cleaning member 421 provided in the first housing 10, and a second cleaning member 422 provided outside the first housing 10, the first cleaning member 421 and the second cleaning member 422 being respectively connected to the mounting shaft 41. In this way, the installation shaft 41 is arranged to penetrate through the first housing 10, so that two ends of the installation shaft 41 can be respectively located in the accommodating space 11 and outside the first housing 10 to be respectively connected with the first cleaning member 421 and the second cleaning member 422, and the first cleaning member 421 and the second cleaning member 422 are driven to rotate together with the installation shaft 41 relative to the first housing 10. Through setting up clean subassembly 42 and including first clean piece 421 and second clean piece 422, make clean subassembly 42 can clean the inner wall and the outer wall of first casing 10 respectively, guarantee the definition of the image that camera 20 took, make supervisory equipment's control quality improve.

The first cleaning member 421 and the second cleaning member 422 are respectively configured to be fitted to the first casing 10. For example, the shapes of the first cleaning member 421 and the second cleaning member 422 are respectively adapted to the shape of the first casing 10, so that the first cleaning member 421 and the second cleaning member 422 can be respectively attached to the inner wall and the outer wall of the first casing 10 and smoothly rotated with respect to the first casing 10.

In one embodiment, the first housing 10 is configured to be hemispherical, and the first cleaning member 421 and the second cleaning member 422 are each configured to be rod-shaped extending along an arc.

By providing the first cleaning member 421 and the second cleaning member 422 to extend in an arc, the contact area of the first cleaning member 421 and the second cleaning member 422 with the first casing 10 is increased, so that the first cleaning member 421 and the second cleaning member 422 clean the first casing 10 more comprehensively.

Alternatively, the first cleaning member 421 and the second cleaning member 422 may be made of rubber.

Fig. 2 is an enlarged view at a in the embodiment shown in fig. 1.

In order to drivingly connect the mounting shaft 41 with the camera head 20 by means of the transmission mechanism 30, the transmission mechanism 30 comprises, in some embodiments, as shown in connection with fig. 1 and 2, a first gear 31, an inner gear ring 35 and a connection member 36. The first gear 31 is sleeved outside the camera 20 around the first axis a so as to rotate along with the camera 20, the annular gear 35 is circumferentially arranged on the inner wall of the first shell 10 around the second axis b, and the annular gear 35 is in transmission connection with the first gear 31 so as to be driven to rotate by the first gear 31; the connecting member 36 is disposed in the accommodating space 11 and is connected with the ring gear 35 and the mounting shaft 41, respectively, to rotate the mounting shaft 41 by means of the ring gear 35. In this way, by arranging the first gear 31 sleeved outside the camera 20 around the first axis a and arranging the annular gear 35 around the second axis b and around the inner wall of the first casing 10, the annular gear 35 is in transmission connection with the first gear 31, so that when the first gear 31 follows the camera 20 to rotate around the first axis a together with the first casing 10, the first gear 31 drives the annular gear 35, and the annular gear 35 rotates around the second axis b relative to the first casing 10. When the ring gear 35 rotates relative to the first housing 10 by providing the connecting members 36 connected with the ring gear 35 and the mounting shaft 41, the ring gear 35 drives the mounting shaft 41 by means of the connecting members 36, so that the mounting shaft 41 rotates together with the ring gear 35 about the second axis b relative to the first housing 10, thereby driving the cleaning assembly 42 connected with the mounting shaft 41 to rotate.

When the first cleaning member 421 and the second cleaning member 422 are made of a material having high elasticity such as rubber, it is difficult for the first cleaning member 421 and the second cleaning member 422 to secure the stability of the power transmission. Therefore, in the above embodiment, the connecting piece 36 is connected with the mounting shaft 41, so as to drive the cleaning assembly 42 to rotate, thereby improving the connection stability between the parts, improving the stability of power transmission and ensuring the cleaning effect of the cleaning assembly 42.

Alternatively, as shown in fig. 1, the connection member 36 is configured to have a rod shape extending in an arc to reduce the influence of the connection member 36 on photographing of the camera 20.

Specifically, as shown in connection with fig. 1-2, the transmission mechanism 30 further includes a second gear 32 meshed with the first gear 31, a third gear 34 coaxially disposed with the second gear 32, and a transmission shaft 33 connected with the second gear 32 and the third gear 34, respectively. The third gear 34 rotates together with the second gear 32 by means of the transmission shaft 33, and the third gear 34 is meshed with the ring gear 35. In this way, by providing the second gear 32 meshed with the first gear 31, the second gear 32 can rotate relative to the first housing 10 about an axis parallel to the first axis a under the driving of the first gear 31, and by providing the third gear 34 in driving connection with the second gear 32 by means of the transmission shaft 33, the third gear 34 can rotate about the rotation axis of the second gear 32, thereby driving the ring gear 35 meshed with the third gear 34 to rotate. Thus, a driving connection of the first gear wheel 31 with the ring gear 35 is achieved, enabling the first gear wheel 31 and the ring gear 35 to rotate simultaneously about different axes.

Specifically, the outer diameter of the second gear 32 is smaller than the outer diameter of the first gear 31. In this way, since the first gear 31 and the second gear 32 are engaged, the linear velocity of the first gear 31 is equal to the linear velocity of the second gear 32, and since the linear velocity is a product of the angular velocity and the radius, the angular velocity of the second gear 32 is greater than the angular velocity of the first gear 31. For example, when the camera 20 rotates the first gear 31 about the first axis a by a small amount, the second gear 32 rotates about its rotation axis by a plurality of rotations, causing the third gear 34 to rotate at the same angular velocity as the second gear 32 by a plurality of rotations. Therefore, the third gear 34 rotates the ring gear 35 and the mounting shaft 41 at a greater rotational speed with respect to the first housing 10, so that the cleaning assembly 42 cleans the first housing 10 at a higher frequency, resulting in improved cleaning efficiency.

Fig. 3 is an assembly schematic diagram of the mounting frame, the cradle head and the camera in the embodiment shown in fig. 1.

To rotate the camera 20 relative to the first housing 10, in some embodiments, as shown in fig. 1 and 3, an opening communicating with the accommodating space 11 is provided on the first housing 10. The monitoring device further comprises a cradle head 50, wherein the cradle head 50 penetrates through the opening and is connected with the camera 20 so as to drive the camera 20 to rotate around the first axis a. In this way, by providing the opening communicating with the accommodating space 11 on the first housing 10, the pan-tilt 50 can pass through the opening and be connected with the camera 20, so as to drive the camera 20 to rotate, and the camera 20 can shoot images in different directions.

For example, the monitoring device may be used for monitoring a power transmission line, and the cradle head 50 is provided to drive the camera 20 to rotate so as to shoot the power transmission line, so that a worker can better know the condition of the power transmission line, and is convenient to deal with the problem in time, and the operation safety of the power transmission line is ensured.

In the actual use process, the operator controls the cradle head 50 through the controller electrically connected with the cradle head 50, so that the cradle head 50 drives the camera 20 to rotate.

To facilitate mounting of the monitoring device, in some embodiments, as shown in fig. 1 and 3, the monitoring device further includes a mounting bracket 60, and a mounting hole penetrating the mounting bracket 60 in a direction parallel to the first axis a is provided on the mounting bracket 60. The cradle head 50 is detachably connected with the mounting frame 60, the cradle head 50 penetrates through the mounting hole, and the first shell 10 is connected with one side, close to the camera 20, of the mounting frame 60. Thus, by providing the mount 60, the cradle head 50 and the first housing 10 can be mounted at a desired position by means of the mount 60, and for example, the mount 60 can be mounted to a power transmission line.

Further, the monitoring device further includes a second housing 70 having an open cavity 71, the second housing 70 is covered on a side of the pan-tilt 50 penetrating through the mounting frame 60 and far away from the camera 20, and the second housing 70 is connected with a side of the mounting frame 60 far away from the camera 20. In this way, the second housing 70 is provided to protect the pan-tilt 50, so as to prevent the pan-tilt 50 from directly contacting with the external environment.

Specifically, the first housing 10 and the second housing 70 are detachably connected to the mounting bracket 60 by a plurality of fasteners, respectively. In one embodiment, the fasteners may be bolts.

Optionally, the holder 50 is detachably connected to the mounting frame 60, so as to facilitate maintenance or replacement of the holder 50.

In some embodiments, the monitoring device further includes a first sealing ring sealed between the first housing 10 and the mounting frame 60, and a second sealing ring sealed between the second housing 70 and the mounting frame 60, so as to separate the interior of the first housing 10 and the second housing 70 from the outside, and protect the cradle head 50 and the camera 20.

Fig. 4 is a partial top view of the pan-tilt, semicircle and mount of the embodiment of fig. 1.

In some embodiments, as shown in fig. 3 and 4, the monitoring device further includes a semicircular ring 80 movably connected to a side of the mounting frame 60 away from the camera 20. One side that mounting bracket 60 and semicircle ring 80 are connected is equipped with at least one recess, is equipped with the first through-hole that corresponds with the recess on the semicircle ring 80, and first through-hole is configured to be can with corresponding recess intercommunication, and one side of the lateral wall of first through-hole is constructed to be the inclined plane, and the aperture that the one end of first through-hole was close to semicircle ring 80 is less than the aperture of the other end of first through-hole. The outer circumferential wall of the pan/tilt head 50 is provided with a first positioning member 90 corresponding to the groove, and the first positioning member 90 is configured to be capable of being matingly connected to the corresponding groove. Thus, the semicircular ring 80 is movably connected with the mounting frame 60, so that the relative position of the semicircular ring 80 and the mounting frame 60 can be changed. Through set up the recess in the one side that mounting bracket 60 and semicircle ring 80 are connected to the first through-hole that corresponds with the recess on semicircle ring 80, make when semicircle ring 80 moves relative mounting bracket 60, can make first through-hole and recess intercommunication, perhaps make semicircle ring 80 shutoff recess. Through setting up the first locating piece 90 that corresponds with the recess at the periphery wall of cloud platform 50, make first locating piece 90 can the matchedly connect in corresponding recess to make cloud platform 50 and mounting bracket 60 joint. When the holder 50 is mounted on the mounting frame 60, the semicircular ring 80 moves relative to the mounting frame 60, so that the first through hole is communicated with the groove, the first positioning piece 90 arranged on the holder 50 enters the groove through the first through hole, and then the semicircular ring 80 moves relative to the mounting frame 60 to seal the groove, so that the first positioning piece 90 is limited in the groove. Therefore, the cradle head 50 and the mounting frame 60 are convenient to assemble and disassemble, the cradle head 50 can be reliably connected with the mounting frame 60, and the positioning accuracy of the mounting is improved.

In some embodiments, one side of the sidewall of the first through hole is configured to be inclined, and an aperture of one end of the first through hole near the semicircle 80 is smaller than an aperture of the other end of the first through hole. Thus, the aperture of the first through hole near one end of the semicircular ring 80 is smaller than that of the other end, so that the first positioning piece 90 easily extends into the first through hole from one end of the first through hole far away from the semicircular ring 80. Through setting up one side of the lateral wall of first through-hole and being the inclined plane, make when installation cloud platform 50, first setting element 90 can be with the lateral wall counterbalance that first through-hole is the inclined plane to when first setting element 90 and cloud platform 50 together move towards the recess direction, first setting element 90 promotes semicircle ring 80, makes semicircle ring 80 relative mounting bracket 60 motion, thereby makes first through-hole and recess intercommunication, in being convenient for make first setting element 90 pass first through-hole entering recess, consequently improved the simple operation of installation cloud platform 50 in-process.

In one embodiment, as shown in fig. 4, the number of the grooves and the first through holes is two, and the two grooves are respectively arranged at two sides of the axis of the mounting hole, so that two opposite sides of the mounting frame 60 are respectively connected with two opposite sides of the holder 50, thereby improving the connection reliability of the mounting frame 60 and the holder 50. In other embodiments, the number of the grooves and the first through holes may be other arrangements according to the use requirement, which is not limited herein.

To enable the semicircle 80 to return after moving relative to the mounting frame 60, in some embodiments, as shown in fig. 4, a fixing member 100 is disposed on a side of the mounting frame 60 where the semicircle 80 is disposed, and the fixing member 100 and one end of the semicircle 80 are disposed at a distance from each other. The monitoring device further includes a first restoring member 110, one end of the first restoring member 110 is connected with the fixing member 100, the other end of the first restoring member 110 is connected with the fixing member 100, and the first restoring member 110 is configured to provide an elastic force that enables the semicircular ring 80 to have a movement tendency toward a direction approaching or away from the fixing member 100, so that the semicircular ring 80 can block the groove.

For example, the first restoring member 110 may be configured to provide an elastic force that causes the semicircular ring 80 to have a tendency to move toward the fixing member 100. In the actual assembly process, when the holder 50 is installed, when the first positioning member 90 extends into the first through hole, the first positioning member 90 abuts against the inclined side wall of the first through hole, so that the semicircular ring 80 moves relatively to the mounting frame 60 in a direction away from the fixing member 100, and meanwhile, the first resetting member 110 is compressed, so that the first through hole is communicated with the groove, and the first positioning member 90 enters the groove. Because the first restoring member 110 has a tendency of restoring the deformation of the first positioning member 90, after the first positioning member 90 is located in the groove, the semicircular ring 80 moves towards the direction close to the fixing member 100 under the elastic force of the first restoring member 110 because the semicircular ring 80 is not subjected to the abutting force of the first positioning member 90 on the semicircular ring 80, so that the semicircular ring 80 seals the groove, and the first positioning member 90 is limited in the groove. When the semicircular ring 80 is detached, the semicircular ring 80 is moved in a direction away from the fixing member 100 relative to the mounting frame 60, and the first positioning member 90 is taken out of the groove through the first through hole.

Thus, by providing the shaft sleeve 62, the frame body 61 is detachably connected with the holder 50 by means of the shaft sleeve 62, thereby facilitating the production and processing of the frame body 61 and the shaft sleeve 62, respectively, and improving the connection reliability of the mounting frame 60 and the holder 50.

In some embodiments, as shown in fig. 3 and 5, the mounting frame 60 is provided with a connection hole, one end of which is communicated with the second through hole, and the other end of which penetrates through the peripheral wall of the mounting frame 60. The plugging mechanism 130 further includes a movable rod 135 movably penetrating the connection hole, and the movable rod 135 is configured to move away from the second through hole when the second positioning member 120 extends into the second through hole. The automatic telescopic rod 131 is configured to be capable of moving towards a direction approaching the second positioning member 120 under the driving of the movable rod 135 so as to abut against the second positioning member 120. Thus, when the second positioning member 120 extends into the second through hole by arranging the movable rod 135, the movable rod 135 moves in a direction away from the second through hole, so as to drive the automatic telescopic rod 131 to move in a direction close to the second positioning member 120 and to be abutted against the second positioning member 120 until the automatic telescopic rod 131 aligns with the positioning hole 121 formed in the second positioning member 120 in a movement process of the second positioning member 120 relative to the mounting frame 60, so as to extend into the positioning hole 121, thereby realizing the fixation of the second positioning member 120. Therefore, the second positioning piece 120 can be positioned by the automatic telescopic rod 131 after being positioned in the second through hole, so that the operation is simple and the positioning is reliable.

To enable the second positioning member 120 to push the movable rod 135 when extending into the second through hole, in some embodiments, an end surface of the second positioning member 120 near one end of the camera 20 is configured to be an inclined surface, and an end surface of the movable rod 135 near one end of the second through hole is configured to be any one of a hemispherical surface, an inclined surface or an arc surface, so that the second positioning member 120 can abut against the movable rod 135, and when one end of the second positioning member 120 moves in the second through hole, the second positioning member 120 can push the movable rod 135 to move in a direction away from the pan-tilt 50, so that the second positioning member 120 continues to extend into the second through hole.

Specifically, the automatically telescopic rod 131 includes a first rod body 1311 and a second rod body 1312 disposed in a direction parallel to the axial direction of the positioning hole 121, and elastic members connected to the first rod body 1311 and the second rod body 1312, respectively. One end of the first rod body 1311 far from the second rod body 1312 abuts against the second positioning element 120, one end of the second rod body 1312 far from the first rod body 1311 is movably connected with the movable rod 135, and the second rod body 1312 is configured to be capable of moving towards a direction approaching to the second positioning element 120 under the driving of the movable rod 135. The elastic member is configured to provide an elastic force that makes the first rod body 1311 have a movement tendency away from the second rod body 1312 along an axial direction thereof so that the first rod body 1311 can be inserted into the second positioning hole 121. In this way, the second rod 1312 is connected to the movable rod 135, so that when the second positioning member 120 extends into the second through hole, the second positioning member 120 abuts against the movable rod 135, thereby pushing the movable rod 135 to move in a direction away from the pan-tilt 50, and the movable rod 135 drives the second rod 1312 to move in a direction close to the second positioning member 120, so that the first rod 1311 abuts against the second positioning member 120. The second positioning member 120 continues to move relative to the mounting bracket 60 until the second moving member moves to a position where the positioning hole 121 is aligned with the first rod 1311. Since the automatic telescopic rod 131 includes an elastic member, the first rod 1311 moves away from the second rod 1312 under the elastic force of the elastic member, and thus extends into the positioning hole 121 to position the second positioning member 120.

To enable the movable rod 135 to move the second rod 1312, in some embodiments, as shown in fig. 5, the plugging mechanism 130 further includes a connecting rod 133, a rotating rod 132, and a fixing rod 134. The connecting rod 133 is connected with one side of movable rod 135 away from the pan-tilt 50, and connecting rod 133 sets up along the direction parallel with first axis a, and the one end of connecting rod 133 is connected with support body 61, and the other end of connecting rod 133 and the one end sliding connection of dwang 132, the other end of dwang 132 and the one end sliding connection of second body of rod 1312 away from first body of rod 1311. One end of the fixing lever 134 is connected to the sleeve 62, and the fixing lever 134 is disposed in a direction perpendicular to the first axis a, and the rotating lever 132 is rotatably connected to the other end of the fixing lever 134. Thus, when the movable rod 135 moves in a direction away from the pan-tilt 50, the movable rod 135 drives the rotating rod 132 to rotate relative to the fixed rod 134, so that the other end of the rotating rod 132 moves in a direction toward the pan-tilt 50, and the second rod 1312 connected to the rotating rod 132 moves in a direction toward the pan-tilt 50. Thus, the holder 50 and the mounting frame 60 are firmly mounted and conveniently assembled and disassembled.

Further, the plugging mechanism 130 includes a second restoring member 136 connected between the sleeve 62 and the fixed rod 134, the second restoring member 136 being spaced apart from the movable rod 135, and the second restoring member 136 being disposed in a direction parallel to the lengthwise extending direction of the movable rod 135, the second restoring member 136 being configured to provide an elastic force that causes the fixed rod 134 to have a tendency to move in a direction approaching the sleeve 62. Therefore, the second resetting piece 136 is arranged, so that after the second positioning piece 120 is separated from the second through hole, the part can be restored to the original state, the tension of the part is maintained, and the part can operate by itself.
