DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The smart grid monitoring device is composed of a linear rail 1, a cover 3, a driving component, a monitoring component, and a charging component 2;

[0029] like Figure 1 , Figure 2 , Figure 8 As shown, according to the specific parts of the base station and the tower that need to be monitored at high altitude, the linear rail 1 is set in the monitoring area, the cover 3 is connected to the linear rail 1 through a driving component, the driving component includes a first motor 35, the first motor 35 is installed inside the cover 3, and two driving gears 31 and two positioning gears 32 are symmetrically rotated on the back of the cover 3. The two driving gears 31 are synchronously rotated in the opposite direction through a gear transmission connection, and the first motor 35 is transmission-connected to one of the driving gears 31. There are buckle grooves 11 on both sides of the linear rail 1, and racks are arranged in the buckle grooves 11. The driving gear 31 and the positioning gear 32 are snapped into the buckle grooves 11 and meshed with the racks. A slider 33 is fixed on the back of the cover 3, and a slide groove 12 is provided on the surface of the linear rail 1. The slider 33 slides linearly in the slide groove 12;

[0030] The housing 3 is internally installed with an energy storage battery, a controller and a communication module. The first motor 35 and the communication module are connected to the controller. The remote control technology of the communication module is an existing technology and will not be described in detail here. The energy storage battery is also equipped with an existing mature power control system so that the power and charging mode of the energy storage battery can be controlled. The energy storage battery is used to supply power to the first motor 35, the controller and the communication module.

[0031] like Figure 3-7 As shown, a charging base 4 is arranged in the housing 3, the charging base 4 includes a carrier 41, a plate frame 6 is fixed to the carrier 41, a plate groove 34 is opened on the inner wall of the housing 3, the plate frame 6 slides linearly with the plate groove 34, a spring is connected between the plate frame 6 and the housing 3, the monitoring component includes two camera components 5, the two camera components 5 are symmetrically rotatably arranged on the surface of the carrier 41, a worm gear is arranged at the rotating part of the camera component 5, a second motor 44 is installed in the carrier 41, a worm 45 is installed on the output shaft of the second motor 44, the worm 45 is meshed and connected to the worm gear, and the second motor 44 and the camera component 5 are connected to the controller and the energy storage battery;

[0032] The camera assembly 5 adopts an existing omnidirectional rotating surveillance camera module, which has the same principle as the existing common omnidirectional angle-adjustable camera module;

[0033] The elastic force of the spring causes the plate frame 6 to slide along the plate groove 34, and the charging seat 4 and the camera assembly 5 are fully extended out of the cover shell 3. The second motor 44 is remotely controlled by the communication module to work. The second motor 44 drives the worm 45 to rotate, and the two camera assemblies 5 are expanded and rotated to both sides through the meshing transmission. The camera assembly 5 can take high-altitude pictures of base stations and power towers. The first motor 35 is turned on to drive the two driving gears 31 to rotate synchronously in the opposite direction. The cover shell 3 moves in a straight line along the linear rail 1 through the meshing transmission of the driving gear 31 and the rack. The camera assembly 5 can be accurately moved to the monitoring location to take pictures and transmit them to the control terminal, so that the operator can obtain the monitoring pictures in a timely and convenient manner.

[0034] The structure of the charging assembly 2 is as follows:

[0035] like Figure 6 , Figure 7 As shown, a charging assembly 2 is arranged at one end of the linear rail 1, and the charging assembly 2 includes a seat body 21, and an active cavity 22 is opened on the surface of the seat body 21. A group of second electrode terminals are arranged in the active cavity 22, and the second electrode terminals are connected to the mains. A group of first electrode terminals are arranged on the end surface of the carrier 41, and the first electrode terminals are connected to the energy storage battery;

[0036] like Figure 6 As shown, the locking assembly includes a card plate 7, which is elastically rotatably mounted on one side of the port of the cover shell 3 through a torsion spring, and the surface of the card plate 7 has two inclined hooks, and the edges of the carrier 41 and the seat body 21 are provided with card slots, and an electromagnetic telescopic rod 46 is installed on the side of the carrier 41, and the electromagnetic telescopic rod 46 is connected to the energy storage battery and the controller, and the electromagnetic telescopic rod 46 is aligned with the card plate 7;

[0037] When in non-monitoring state or when the power of the energy storage battery is low, the controller controls the second motor 44 to drive the worm 45 to reverse, so that the two camera assemblies 5 shrink and move closer to the center, and at the same time turns on the first motor 35 to drive the cover 3 to move in the direction of the charging assembly 2, and the carrier 41 first contacts the seat body 21. At this time, the first electrode terminal is inserted into the movable cavity 22 and contacts the second electrode terminal. Since the carrier 41 and the seat body 21 are in contact and cannot move, the cover 3 is continuously moved to cover the outside of the camera assembly 5 and the charging seat 4, and the inclined surface of the hook of the card plate 7 contacts the edge expansion of the carrier 41 and the seat body 21. When the two hooks are aligned with the two slots, the hooks are inserted into the slots to lock the cover 3, the carrier 41, and the seat body 21 together, and the camera assembly 5 is covered and protected by the cover 3. The first electrode terminal contacts the second electrode terminal to charge the energy storage battery.

[0038] When the monitoring task is performed again, the controller controls the electromagnetic telescopic rod 46 to extend and contact the card plate 7, so that the card plate 7 rotates outward, the hook disengages from the card slot, and the elastic action first moves the cover 3 to expose the charging seat 4 and the camera assembly 5, and then the charging seat 4 and the camera assembly 5 move synchronously with the cover 3 to the monitoring position.

[0039] like Figure 6 , Figure 7 As shown, an inclined surface stopper 25 is elastically slidably installed at the port of the active cavity 22, the inclined surface of the inclined surface stopper 25 points to the carrier 41, and the inclined surface stopper 25 is used to block the port of the active cavity 22. An inclined surface plug 42 is fixed on the end surface of the carrier 41, and the first electrode terminal is arranged on one side of the inclined surface plug 42. A blocking piece 43 is elastically slidably arranged on the surface of the inclined surface plug 42, and the blocking piece 43 is used to shield the first electrode terminal;

[0040] When performing the detection task, the charging mode is disconnected, the inclined block 25 blocks the port of the active cavity 22, and the blocking piece 43 moves to block the first electrode terminal, so that the first electrode terminal and the second electrode terminal are both blocked and protected to prevent dust and moisture from adhering to the surfaces of the first electrode terminal and the second electrode terminal. When charging, the inclined surface of the inclined plug block 42 contacts the inclined block 25, so that the inclined block 25 moves laterally to open the active cavity 22, and the inclined plug block 42 is inserted into the active cavity 22. During the insertion process, the blocking piece 43 is blocked by the port of the active cavity 22 and cannot enter, so that the blocking piece 43 and the inclined plug block 42 are misaligned, so that the first electrode terminal inserted into the active cavity 22 is exposed, and the first electrode terminal contacts the second electrode terminal for charging.

[0041] like Figure 6 , Figure 7 As shown, the size of the seat body 21 is adapted to the port of the cover shell 3, and the port of the cover shell 3 can be slidably mounted on the outer side of the seat body 21 to increase the sealing effect. The movable block 23 is elastically and slidably installed inside the movable cavity 22, and the second electrode terminal is arranged on the surface of the movable block 23. The movable block 23 is fixed with a contact handle 24, and the contact handle 24 has a spherical end that slides through the surface of the seat body 21. When charging, the port of the cover shell 3 is sleeved on the outside of the seat body 21, and at the same time, the spherical end of the contact handle 24 is squeezed to make the contact handle 24 and the movable block 23 move laterally, so as to squeeze the second electrode terminal and the first electrode terminal into contact, thereby improving the connection stability of the conductive part and avoiding overheating or circuit breaking due to loose contact.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
