Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle (UAV) ultraviolet detection, and particularly relates to a UAV-borne ultraviolet detection device for power line discharge. Background Art

[0002] Existing power line discharge detections usually include infrared imaging method, ultraviolet imagers used in foreign markets, etc. Among them, the pulse current method, which is relatively mature and has been used earlier, is the most widely used. These methods for detecting power line discharge by infrared imaging, ultraviolet imagers, and pulse current have many defects. In the case of weak discharges such as general corona of power lines, the power lines heat very little, and the power line discharge cannot be detected at all by the infrared imaging method. Moreover, the infrared imaging method is greatly affected by the environment. Interference from the sun and background radiation, selection of spectral emissivity, focusing conditions, meteorological conditions, etc. will all have a great impact on the detection results. The ultraviolet imager is only most widely used in some developed countries. The ultraviolet imager is expensive and has a high cost. When using the ultraviolet imager for detection, there are certain requirements for the distance between the ultraviolet signal generated by the power line discharge and the ultraviolet imager.

[0003] Chinese Patent (the authorization announcement number is: CN212872738U, and the authorization announcement date is: April 2, 2021) proposes a UAV-borne ultraviolet detection device for power line discharge, which includes a UAV, an ultraviolet detection device, and a rotating rod; the ultraviolet detection device is arranged on the UAV through the rotating rod. The ultraviolet detection device includes an ultraviolet probe, a display screen, and a power switch arranged on the outside of the ultraviolet detection device, and a detection module arranged on the inside of the ultraviolet detection device. The utility model discloses a UAV-borne ultraviolet detection device for power line discharge. By using the ultraviolet pulse method, the UAV-borne ultraviolet detection device for power line discharge is used for detecting large power systems, and it can realize early detection and early treatment of the leakage discharge situation of its transmission lines; this discharge detection device can realize detection at a relatively long distance, thereby improving the safety factor of power line discharge detection.

[0004] After the detection of the existing UAV-borne ultraviolet detection device for power line discharge is completed, when the UAV flies back, the detector at the lower end of the UAV is likely to collide with other sundries during the recovery process and be damaged. Moreover, the detector needs to be disassembled and installed in a protective box after use, resulting in inconvenient installation and use of the detector. Therefore, we propose a UAV-borne ultraviolet detection device for power line discharge. Content of the Utility Model

[0015] 2) When the detector needs to be used and the protective cover needs to be rotated, and the protective cover is covered on the observation end of the detector, the electric telescopic rod is started, and the electric telescopic rod pushes the pushing block to start moving, so that the moving rod drives the slider to start moving, and the pushing rod drives the gear rod to move, and the rotating gear starts to rotate, so that the transmission rod starts to rotate, and the cleaning rod rotates, so that the dust removal block installed on the cleaning rod cleans the observation end of the detector, and the moving rod moves to drive the slider to move, so that the fixing bolt moves and contracts, so that the protective cover is detached, and the drive motor is started to rotate the protective cover, so that the observation end of the detector is kept clean.

Specific implementation mode

[0023] The following will describe the present utility model in detail in combination with the specific implementation modes shown in the drawings. However, these implementation modes do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation modes is included within the protection scope of the present utility model.

[0024] Embodiment 1: As Figure 1-6 shown, the present utility model includes a drone 1, and a protection mechanism is provided at the lower end of the detection of the drone 1. The protection mechanism includes a protection cover 201 and a detector 204 that rotates with the protection cover 201. Specifically, when the protection cover 201 rotates, the drive mechanism drives the detector 204 to start rotating through the connection mechanism at the output end, so that the use and storage of the detector 204 are more convenient. And the above detector 204 is prior art and will not be elaborated here. A cleaning and fixing mechanism is provided at one end of the protection cover 201 close to the detector 204. The cleaning and fixing mechanism includes a fixing bolt 310 for fixing the protection cover 201 and a cleaning rod 311 that rotates with the fixing bolt 310. Specifically, the fixing bolt 310 fixes the protection cover 201. When the fixing bolt 310 moves, the transmission mechanism drives the cleaning rod 311 to start rotating to clean the observation end of the detector 204.

[0025] A fixed rod 212 is rotatably installed at the lower end of the drone 1. One end of the fixed rod 212 is fixedly installed with a driven gear 211, and the protective cover 201 is fixedly installed on the outer wall of the fixed rod 212. An installation cover 214 is fixedly installed on the outer wall of the drone 1 near the driven gear 211, and the driven gear 211 is rotatably installed on the inner wall of the installation cover 214. The installation cover 214 installed at the lower end of the drone 1 can prevent sundries from colliding with the driven gear 211 and causing damage to the driven gear 211. The driven gear 211 is meshed with a transmission gear 208, the transmission gear 208 is meshed with a driving gear 207, and the upper end of the driving gear 207 is fixedly installed with a driving motor 206. The driving motor 206 is fixedly installed in the vacant part provided in the drone 1, so as to prevent the driving motor 206 from moving and being damaged after the driving motor 206 is started.

[0026] The lower end of the driving gear 207 is fixedly installed with a rotating rod 209, the lower end of the rotating rod 209 is fixedly installed with a winding cylinder 210, and a connecting line 213 is wound on the outer wall of the winding cylinder 210. After the driving motor 206 is started, the driving gear 207 drives the connecting line 213 to wind during rotation, so that the protective cover 201 and the detector 204 rotate simultaneously. One end of the connecting line 213 away from the winding cylinder 210 is fixedly installed with a pulling rod 205. A mounting rod 202 is rotatably installed on the inner wall of the drone 1 near the pulling rod 205, and the pulling rod 205 is fixedly installed on the outer wall of the mounting rod 202. When the connecting line 213 pulls the pulling rod 205, the mounting rod 202 rotates to move the detector 204 out of the drone 1. A winding spring 203 is fixedly installed at the connection between the drone 1 and the mounting rod 202, and the detector 204 is fixedly installed at the lower end of the outer wall of the mounting rod 202.

[0027] Working principle: When the detector 204 needs to be used, start the driving motor 206, the driving gear 207 rotates, the transmission gear 208 drives the driven gear 211 to rotate, the mounting rod 202 rotates, and the protective cover 201 rotates to the vacant part provided in the drone 1. At the same time that the driving gear 207 drives the transmission gear 208 to rotate, the rotating rod 209 fixedly installed at the upper end of the driving gear 207 starts to rotate, so that the winding cylinder 210 starts to rotate and wind the connecting line 213, the connecting line 213 drives the pulling rod 205 to start rotating, and the pulling rod 205 drives the fixed rod 212 to rotate, so that the detector 204 extends out while the protective cover 201 is opened. When storage is needed, reverse-start the driving motor 206, the protective cover 201 starts to rotate in the reverse direction, and the winding spring 203 pushes the mounting rod 202 to rotate, so that the detector 204 is retracted. Thus, when the detection device is not needed, the detection device is stored in the drone 1 to prevent the detector 204 from colliding with other sundries and being damaged when not in use.

[0028] Embodiment 2:

[0029] As Figure 1-6 shown, an installation box 301 is fixedly installed at the upper end of the protective cover 201. A limiting groove 307 is provided at the fixed installation part of the upper end of the protective cover 201 close to the installation box 301. The limiting groove 307 installed on the installation box 301 prevents the pushing block 303 from moving downward during the movement process and plays a role in guiding the movement. A pushing block 303 is slidably installed in the limiting groove 307. An electric telescopic rod 302 is fixedly installed at the side end of the pushing block 303, and the electric telescopic rod 302 is fixedly installed on the inner wall of the installation box 301. The electric telescopic rod 302 is fixedly installed on the inner wall of the installation box 301, so as to avoid damage caused by the movement of the electric telescopic rod 302 after it is started as much as possible.

[0030] A moving rod 308 is fixedly installed at the lower end of the pushing block 303. A slider 309 is fixedly installed at one end of the moving rod 308 away from the pushing block 303. A chute is provided on one side of the protective cover 201 close to the slider 309. The chute provided on the protective cover 201 prevents the slider 309 from shifting during the process. A fixing bolt 310 is fixedly installed at the side end of the slider 309 away from the moving rod 308. A fixing hole is provided at the position of the drone 1 close to the fixing bolt 310. The fixing hole provided on the drone 1 makes it more convenient for the fixing bolt 310 to be inserted into the drone 1.

[0031] A toothed rod 304 is fixedly installed at the side end of the pushing block 303 away from the electric telescopic rod 302. One end of the toothed rod 304 away from the pushing block 303 is meshed with a rotating gear 305. A transmission rod 306 is fixedly installed at the lower end of the rotating gear 305. The transmission rod 306 rotates through the protective cover 201. The transmission rod 306 rotatably installed in the protective cover 201 makes it more convenient for the rotating gear 305 to drive the cleaning rod 311 to rotate after rotation. A protective cover 215 is fixedly installed on the lower end of the protective cover 201 close to the transmission rod 306. The transmission rod 306 passes through the protective cover 215. The protective cover 215 prevents the observation end of the detector 204 from colliding with other sundries and being damaged after being stored. A cleaning rod 311 is fixedly installed at the lower end of the transmission rod 306. A plurality of dust removal blocks 312 are slidably installed at the lower end of the cleaning rod 311. The dust removal blocks 312 slidably installed at the lower end of the cleaning rod 311 enable the dust removal blocks 312 to fit on the surface of the observation end of the detector 204 when the cleaning rod 311 rotates to clean the observation end of the detector 204, making the cleaning more convenient.

[0032] Working principle: When it is necessary to use the detector 204 and the protective cover 201 needs to be rotated, and the protective cover 215 covers the observation end of the detector 204, the electric telescopic rod 302 is started. The electric telescopic rod 302 pushes the pushing block 303 to start moving, causing the moving rod 308 to drive the slider 309 to start moving, and the pushing rod drives the rack 304 to move. The rotating gear 305 starts to rotate, causing the transmission rod 306 to start rotating, and the cleaning rod 311 rotates, so that the dust removal block 312 installed on the cleaning rod 311 performs dust cleaning work on the observation end of the detector 204. When the moving rod 308 moves, it drives the slider 309 to move, causing the fixing bolt 310 to move and contract, so that the protective cover 201 is disengaged. The driving motor 206 is started to rotate the protective cover 201, so as to keep the observation end of the detector 204 clean.
