Description

Technical Field

[0001] The invention relates to the technical field of snow removal devices, and in particular to a substation-supported porcelain bottle snow removal device based on an unmanned aerial vehicle. Background Art

[0002] After snowfall in winter, in order to ensure the safe operation of equipment, it is necessary to clean the snow on the porcelain bottles supporting the high-voltage equipment of the substation in time after the snowfall ends to prevent the formation of icicles after the ice and snow melt. If the icicles extend or form across the sheds, it is very likely to cause a discharge path, causing the substation equipment to short-circuit and trip, seriously affecting the reliability of power supply safety.

[0003] At present, there are two common methods for substations to clean the supporting porcelain bottles after snowfall. First, the substation staff use an insulating operating rod to clean the snow. Because the porcelain bottles covered with snow and snow have high voltage, and the voltage of some substations is as high as 220kV and 500kV or above, the staff need to wear insulating gloves and insulating shoes. At the same time, the insulating rod must be of sufficient length, and a broom must be tied to the top of the insulating rod to sweep away the snow on the porcelain bottles. The second is to use electric equipment to remove snow. The common practice is to tie an electric fan blade on the top of the insulating rod, which can save manpower.

[0004] There are great safety hazards in the process of snow removal at the substation. The porcelain bottles of the substation pillars carry high voltage. Because the porcelain bottles are covered with snow, the insulation degree of the porcelain bottles of the substation is greatly reduced. Although the workers use insulating tools, such as holding insulating rods, wearing insulating gloves, and wearing insulating shoes or insulating boots, the above insulating tools and insulating protective equipment will inevitably be stained with snow during snow removal, which will reduce the insulation performance of the insulating tools and insulating protective equipment. In severe cases, creepage will occur on insulating tools such as insulating rods, seriously endangering the personal safety of the workers. Summary of the invention

[0022] See also Figures 1 to 7 , a substation supporting porcelain bottle snow removal device based on a drone is provided in one embodiment of the present invention, comprising a drone 1, two sets of connecting rods 11 are fixedly installed at the bottom of the drone 1, and also includes: The connecting mechanism 2 includes a mounting plate 21, and two groups of jacks 22 are provided on the surface of the mounting plate 21. The connecting rod 11 is movably inserted into the inside of the jacks 22. An abutment block 12 is fixedly installed at the end of the connecting rod 11. The abutment block 12 is hemispherical. A symmetrical clamping block 25 is slidably connected inside the mounting plate 21. The clamping block 25 is movably fitted with the surface of the abutment block 12. When the abutment block 12 is inserted into the inside of the jack 22, the clamping block 25 limits the abutment block 12, thereby realizing the connection between the mounting plate 21 and the connecting rod 11; The snow removal mechanism 3 includes a chassis 31, a motor 34 is installed inside the chassis 31, a transmission rod 35 is coaxially connected to the output shaft end of the motor 34, a rotating block 36 is fixedly installed on the surface of the transmission rod 35, and two sets of fan blades 32 are installed on the rotating block 36. The motor 34 is switched on and off by remote control and drives the fan blades 32 to rotate, so as to remove the snow on the surface of the supporting porcelain bottle; The positioning docking part includes a trapezoidal positioning seat 58 provided at the bottom of the drone 1 and a receiving seat 510 provided above the mounting plate 21. The receiving seat 510 is provided with a trapezoidal positioning groove 57 which is opposite to and matched with the trapezoidal positioning seat 58. The drone 1 is provided with a telescopic part connected to the connecting rod 11; The UAV 1 and the snow removal mechanism 3 are connected by the connecting mechanism 2 and are positioned and docked between the trapezoidal positioning seat 58 and the receiving seat 510. Through the setting of the connecting mechanism 2, when the UAV 1 is flying, the snow removal mechanism 3 can be automatically mounted and separated through the connecting mechanism 2, and the snow removal mechanism 3 can be driven to fly, so that the snow removal mechanism 3 can be moved to the position where snow removal is required to perform snow removal work; Connecting brackets 28 are fixedly mounted on both sides of the surface of the mounting plate 21 , and ends of the connecting brackets 28 are fixedly connected to the upper surface of the chassis 31 .

[0023] Specifically, a limit block 14 is fixedly installed on the surface of the connecting rod 11, and a sliding block 13 is slidably connected between the limit block 14 and the abutment block 12. Both sides of the sliding block 13 are arranged in an inclined state, and the clamping block 25 is movably fitted with both sides of the sliding block 13. A sliding block groove 15 is opened on the surface of the abutment block 12, and one side of the sliding block 13 is slidably connected to the inside of the sliding block groove 15.

[0024] In the embodiment of the present invention, the drone 1 drives the connecting rod 11 to continue to move downward inside the socket 22, and the block 25 contacts one side of the sliding block 13. Due to the resistance of the limit block 14, the block 25 is squeezed by the sliding block 13 again and retracted into the slot 23 and pops out on the other side of the sliding block 13. At this time, the drone 1 moves up. Since both sides of the sliding block 13 are set to be inclined, the sliding block 13 is moved to the sliding block slot 15 inside the abutment block 12 by the downward force of the block 25, forming a whole with the abutment block 12. After being squeezed by the sliding block 13 and the abutment block 12, the block 25 returns to the slot 23 again, and the connecting rod 11 is moved out of the socket 22 as a whole.

[0025] Specifically, a card slot 23 is opened on both sides of the mounting plate 21 near the socket 22, a card block 25 is slidably connected inside the card slot 23, a moving rod 24 is fixedly installed on one side of the card block 25, a fixing ring 26 is fixedly installed inside the card slot 23, the moving rod 24 is slidably connected between the card slot 23 and the fixing ring 26, a spring 27 is fixedly installed on the surface of the fixing ring 26, the other end of the spring 27 is fixedly connected to one side of the card block 25, and the moving rod 24 runs through the inside of the spring 27.

[0026] In the embodiment of the present invention, when the drone 1 is flying, it drives the connecting rod 11 to be inserted into the socket 22 on the surface of the mounting plate 21. The drone 1 is adjusted downward, and the abutment block 12 at the end of the connecting rod 11 contacts the clamping block 25, squeezing the two clamping blocks 25 back into the clamping groove 23. The abutment block 12 continues to move downward, and the clamping block 25 is re-popped out to the upper surface of the abutment block 12 under the action of the spring 27 and the fixing ring 26 to limit the abutment block 12.

[0027] It should be supplemented that a first strip groove 51 is provided in the middle position inside the bottom casing of the drone 1, a second strip groove 52 is provided on one side of the first strip groove 51, a first rack 53 and a second rack 54 are movably provided inside the first strip groove 51 and the second strip groove 52, respectively, the first rack 53 and the connecting rod 11 are fixed, a gear 55 is provided between the first rack 53 and the second rack 54, the gear 55 is rotatably installed inside the bottom casing of the drone 1 through a rotating shaft, and the gear 55 is meshed with the first rack 53 and the second rack 54 at the same time, and a first return spring 56 is connected between the top of the second rack 54 and the top wall of the second strip groove 52; A receiving seat 510 is provided above the mounting plate 21, and a trapezoidal positioning groove 57 is provided on the surface of the receiving seat 510. A trapezoidal positioning seat 58 is fixed to the bottom end of the bottom casing of the drone 1. The first strip groove 51 and the second strip groove 52 simultaneously penetrate the trapezoidal positioning seat 58, and the first rack 53 and the second rack 54 can both extend from the trapezoidal positioning seat 58. The trapezoidal positioning seat 58 and the trapezoidal positioning groove 57 are opposite to each other, and the sizes and shapes of the two are matched with each other. Both side surfaces of the two are smooth inclined surfaces. This arrangement is conducive to the precise docking between the drone 1 and the receiving seat 510. When the drone 1 flies above the mounting plate 21, the trapezoidal positioning seat 58 will first be moved. Into the trapezoidal positioning groove 57, since both are trapezoidal and both side surfaces of the two are smooth inclined surfaces, when the two are docked, even if they are not completely aligned, as long as the inclined surfaces of the two are in contact with each other, as the drone 1 continues to descend, the inclined surfaces on both sides are constantly in contact and corrected, and finally the docking position of the drone 1 can be adjusted to achieve precise docking with the receiving seat 510, and it can also ensure that the connecting rod 11 is more accurately docked with the socket 22, and a plurality of second reset springs 59 are connected between the receiving seat 510 and the mounting plate 21. The presence of the second reset springs 59 ensures that the receiving seat 510 and the mounting plate 21 maintain a certain distance in the initial state.

[0028] A fixed push bar 513 is installed in the trapezoidal positioning groove 57 at a position opposite to the second rack 54. In the initial state, the first return spring 56 is stretched, and the end of the second rack 54 extends out of the second strip groove 52, while the first rack 53 and the entire connecting rod 11 are located in the first strip groove 51. During use, when snow removal tasks are required, the drone 1 flies to the top of the corresponding snow removal mechanism 3 through the built-in high-precision locator and ultrasonic radar, and descends vertically through remote control commands. When descending, it drives the connecting rod 11 downward and inserts it into the socket 22 of the mounting plate 21 on the upper surface of the snow removal mechanism 3 below. During this process, the trapezoidal positioning seat 58 will first enter the trapezoidal positioning groove 57. Since both are trapezoidal and both side surfaces of both are smooth inclined surfaces, when the two are docked, even if they are not fully aligned, as long as the inclined surfaces of the two are in contact with each other, as the drone 1 continues to descend, the inclined surfaces on both sides are constantly contacted and corrected, and finally the docking position of the drone 1 can be adjusted to achieve and support. The precise docking between the receiving seats 510 can also ensure that the connecting rod 11 is more accurately docked with the socket 22. At this time, the connecting rod 11 is aligned with the socket 22, and the drone 1 continues to move downward. The fixed push bar 513 will first contact the second rack 54, and as the drone 1 continues to move downward, the second rack 54 is pushed to move upward continuously, and the first return spring 56 is compressed. In the process of the second rack 54 moving upward continuously, the gear 55 is driven to rotate, thereby driving the first rack 53 and the connecting rod 11 to move downward, thereby pushing the connecting rod 11 to move into the socket 22 until the abutment block 12 at the end of the connecting rod 11 is stuck by the block 25. At this time, the drone can drive the entire snow removal mechanism 3 to move; when the snow removal task is completed, the drone 1 and The snow removal mechanism 3 is separated, and the UAV 1 moves downward first. Due to the presence of the second return spring 59, the receiving seat 510 and the mounting plate 21 maintain a certain distance in the initial state, which provides moving space for the UAV 1 to continue to move downward. The connecting rod 11 continues to be pushed downward, and the block 25 contacts one side of the sliding block 13. Due to the resistance of the limit block 14, the block 25 is squeezed by the sliding block 13 again and retracted into the slot 23. After the sliding block 13 continues to move downward and passes over the block 25, the block 25 pops out from the empty space between the sliding block 13 and the limit block 14 under the action of the elastic force. At this time, the UAV 1 is controlled to move upward, and the sliding block 13 is squeezed and moved to the sliding block inside the abutment block 12 after being subjected to the downward force of the lower surface of the block 25. The block 25 is squeezed by the upper inclined surface of the sliding block 13 and returns to the inside of the card slot 23. The sliding block 13 and the abutment block 12 at the end of the connecting rod 11 are moved out of the inside of the socket 22 as a whole, so that the drone 1 and the snow removal mechanism 3 can be automatically separated. After separation, there is no downward pressure from the second rack 54 on the fixed push bar 513, so the elastic force of the first return spring 56 will push the second rack 54 downward, thereby driving the connecting rod 11 to move upward. As the drone 1 continues to move upward, the entire connecting rod 11 will be completely immersed in the first strip groove 51, and the receiving seat 510 will extend and automatically reset under the elastic force of the second return spring 59, ready for the next docking. Specifically, a controller 33 is fixedly installed on the surface of the chassis 31, and the controller 33 is electrically connected to the motor 34. The motor 34 is started by the controller 33, and the motor 34 drives the transmission rod 35 to rotate. The rotating block 36 on the surface of the transmission rod 35 drives the two groups of fan blades 32 to rotate, thereby achieving the snow processing work on the surface of the supporting porcelain bottle.

[0029] Specifically, two groups of batteries 37 are fixedly installed inside the chassis 31, and the two groups of batteries 37 supply power to the motor 34. Two groups of symmetrical through grooves 38 are opened on the surface of the chassis 31, and the ends of the fan blades 32 extend from the through grooves 38 and can rotate along the through grooves 38.

[0030] Specifically, an ice breaking mechanism 4 is provided below the snow removal mechanism 3. The ice breaking mechanism 4 includes an ice breaking knife 41. The ice breaking knife 41 is used to remove ice on the lower surface of the supporting porcelain bottle.

[0031] In the embodiment of the present invention, the ice-breaking knife 41 reciprocates under the supporting porcelain bottle to remove ice from the lower surface of the supporting porcelain bottle.

[0032] Specifically, an L-shaped plate 45 is fixedly installed on the lower surface of the chassis 31, and a movable seat 48 is slidably connected to the surface of the L-shaped plate 45. The icebreaker 41 is fixedly installed on the surface of the movable seat 48. A movable space is set between the L-shaped plate 45 and the lower surface of the chassis 31, and the icebreaker 41 is located inside the movable space.

[0033] In the embodiment of the present invention, the L-shaped plate 45 is provided to provide support for the movement of the icebreaker 41 driven by the movable seat 48, and the moving space between the L-shaped plate 45 and the chassis 31 provides space for the movement of the icebreaker 41.

[0034] Specifically, the ice-breaking mechanism 4 also includes a rotating bracket 42, which is rotatably connected to the inside of the chassis 31, and a driven sprocket 43 is fixedly installed on one end of the rotating bracket 42. A driving sprocket 39 is fixedly installed on the surface of the transmission rod 35, and a chain 401 is meshed between the driving sprocket 39 and the surface of the driven sprocket 43.

[0035] In the embodiment of the present invention, the driving sprocket 39 , the driven sprocket 43 and the chain 401 are meshed, so that the transmission rod 35 rotates and the rotating bracket 42 can rotate at the same time.

[0036] Specifically, a first bevel gear 44 is fixedly installed on the other end of the rotating bracket 42, a reciprocating bracket 46 is rotatably connected to the surface of the L-shaped plate 45, a second bevel gear 47 is fixedly installed on the surface of the reciprocating bracket 46, the first bevel gear 44 is meshed with the second bevel gear 47, and the moving seat 48 is threadedly connected to the surface of the reciprocating bracket 46.

[0037] In the embodiment of the present invention, the first bevel gear 44 at one end of the rotating bracket 42 is meshed with the second bevel gear 47 on the surface of the reciprocating bracket 46, so that the reciprocating bracket 46 can rotate, and the moving seat 48 on the surface of the reciprocating bracket 46 drives the ice-breaking knife 41 to move under the supporting porcelain bottle to perform ice-breaking work.

[0038] Specifically, a support plate 402 is fixedly installed on one side of the L-shaped plate 45 , a guide rod 49 is fixedly installed between the support plate 402 and the L-shaped plate 45 , and the movable seat 48 is slidably connected to the surface of the guide rod 49 .

[0039] In the embodiment of the present invention, the guide rod 49 makes the movable base 48 more stable when moving.

[0040] When in use, the snow removal mechanism 3 is usually arranged and placed in a special loading center of the State Grid. The drone is usually not loaded with the snow removal mechanism 3 and performs other tasks (such as aerial photography, point cloud scanning, etc.). When snow removal tasks are required, the drone 1 flies to the top of the corresponding snow removal mechanism 3 through the built-in high-precision locator and ultrasonic radar, and descends vertically through remote control instructions. When descending, it drives the connecting rod 11 downward and inserts it into the socket 22 of the mounting plate 21 on the upper surface of the snow removal mechanism 3 below. The drone 1 continues to descend, and the abutment block 12 at the end of the connecting rod 11 contacts the card block 25, squeezing the two card blocks 25 back into the card slot 23, and the abutment block 12 continues to move downward. The card block 25 is re-popped out to the upper surface of the abutment block 12 under the action of the spring 27 and the fixing ring 26 and limits the abutment block 12, thereby completing the mounting of the drone 1 and the snow removal mechanism 3. At this time, the drone 1 can fly again with the mounted snow removal mechanism 3 to go to the mission location to perform snow removal tasks.

[0041] When the snow removal mechanism 3 moves to the snow removal position, the controller 33 is used to make the motor 34 and the fan blades 32 work simultaneously, and the motor 34 drives the transmission rod 35 to rotate, and the rotating block 36 on the surface of the transmission rod 35 drives the two groups of fan blades 32 to rotate, so as to achieve the snow processing work on the surface of the supporting porcelain bottle in a larger range. At the same time, an ice breaker 41 is arranged between the chassis 31 and the L-shaped plate 45. Through the engagement of the active sprocket 39, the driven sprocket 43 and the chain 401, the transmission rod 35 rotates and the rotating bracket 42 can rotate at the same time. The first bevel gear 44 at one end of the rotating bracket 42 is engaged with the second bevel gear 47 on the surface of the reciprocating bracket 46, so that the reciprocating bracket 46 can rotate, and the moving seat 48 on the surface of the reciprocating bracket 46 drives the ice breaker 41 to move under the supporting porcelain bottle to perform ice breaking.

[0042] When the task is completed and the drone 1 needs to be separated from the snow removal mechanism 3, the drone 1 first lands with the snow removal mechanism 3. After the snow removal mechanism 3 lands, the drone 1 continues to descend vertically, driving the connecting rod 11 to continue to move downward inside the socket 22, and the block 25 contacts one side of the sliding block 13. Due to the resistance of the limit block 14, the block 25 is squeezed by the sliding block 13 and retracted into the slot 23 again. After the sliding block 13 continues to move downward and passes over the block 25, the block 25 is retracted in the sliding slot 23 under the action of the elastic force. The sliding block 13 pops up from the empty space between the moving block 13 and the limiting block 14, and the drone 1 is controlled to move upward at this time. The sliding block 13 is squeezed and moved into the sliding block groove 15 inside the abutting block 12 by the downward force of the lower surface of the card block 25, and forms a whole with the abutting block 12. The card block 25 is squeezed by the inclined surface of the upper surface of the sliding block 13 and returns to the inside of the card groove 23 again.
