Description

Electric wire netting inspection equipment and protector thereof

Technical Field

The utility model relates to power grid inspection, in particular to power grid inspection equipment and a protection device thereof.

Background

The safe and stable operation of the power grid plays a vital role in ensuring the normal development of enterprise production and people life, strengthens the inspection work of the power grid, discovers potential hazards possibly existing in the power grid in time, and can effectively avoid accidents. With the need of the development of the power grid technology, the manual inspection mode cannot completely adapt to the actual requirement of the development of the power grid, so that unmanned inspection technology is generated. The unmanned inspection technology is also called as an unmanned inspection technology for power grid faults, and can rapidly, efficiently and accurately shoot specific targets, so that rich and detailed power grid data are provided for power grid management staff, and support is provided for later maintenance and development of maintenance work.

In the prior art, an unmanned aerial vehicle is generally adopted to be combined with a detection device such as a camera and the like to serve as power grid fault unmanned inspection equipment, however, due to the fact that the unmanned aerial vehicle needs to be in a high-altitude environment for a long time, substances such as water mist dust and the like in air are easy to adhere to the surface of a camera lens, or the unmanned aerial vehicle is not operated properly in a power grid, so that a detection picture is unclear or the lens is damaged permanently. For example, patent document 1 (CN 216102828U), which describes a protection structure of an unmanned aerial vehicle lens, including an unmanned aerial vehicle body, a camera lens and a transparent glass protection plate, which can protect the camera lens, avoid the problem that an object touches the camera lens during the flying process, and when the protection plate is used for a long time, it also starts the cleaning rod to move through the motor to remove dust and attachments on the surface of the protection plate. Also for example, patent document 2 (CN 217893252U), which describes a detection protection line inspection unmanned aerial vehicle, including an unmanned aerial vehicle body, a protection housing, a driving motor, a monitoring camera, a cleaning brush, and the like, can clean a camera lens in time.

However, there are few effective and durable protection schemes or protection devices for critical parts (such as a lens) of the detection device in the prior art, for example, when wind sand or wind snow weather is encountered during the power grid inspection, the schemes described in patent document 1 and patent document 2 only clean the lens of the camera to achieve clear image capture, and dust and sand particles still cause permanent damage to the surface of the lens.

The utility model provides power grid inspection equipment and a protecting device thereof, wherein the protecting device is used for protecting an image detecting device in the power grid inspection equipment. In some examples, the protective device of the grid inspection device may also be referred to as a "protective device," "protective structure," or "protective device," or the like. In some examples, a grid patrol device may refer to a device, instrument, or apparatus for performing fault patrol in a grid. In some examples, grid patrol may include transmission grid and distribution grid patrol.

For convenience of explanation, the description will be first made starting from the power grid inspection device. Fig. 1 is a schematic diagram showing the overall structure of a power grid inspection apparatus 10 according to an example of the present utility model. Fig. 2 is a schematic diagram showing a partially disassembled structure of the power grid inspection apparatus 10 of fig. 1.

As shown in fig. 1 and 2, in some examples, the grid inspection device 10 may include a cradle head 13, an aircraft body 11, a shock absorbing device 12, an image detection device 14, and a guard device 15. It should be noted that the guard 15 may be any guard 15 described below, particularly with reference to the description of the guard 15 below.

In some examples, the aircraft body 11 may be used to fly to a designated location of the electrical grid. In some examples, the aircraft body 11 may be a rotorcraft. In some examples, the aircraft body 11 may be coupled in-line with the hover rod 16. In some examples, the number of hover bars 16 may be multiple. In some examples, the overall size of the plurality of suspension rods 16 when connected to the aircraft body 11 may be greater than the overall size of three of Yu Yuntai, image detection device 14, and protective device 15. In this case, it is possible to reduce the damage of the pan-tilt 13, the image detection device 14, and the protection device 15 by touching the landing point when the aircraft body 11 is landed at the landing point, or to reduce the damage of the pan-tilt 13, the image detection device 14, and the protection device 15 caused by collision with an obstacle during flight.

In some examples, the image detection device 14 may be used to detect images, such as photographs, cameras, or imaging using thermal imaging principles, etc. In some examples, the image detection device 14 may be provided to the pan/tilt head 13.

In some examples, cradle head 13 may be used to connect to aircraft body 11 and may carry image detection device 14. In this case, the image detection device 14 and the aircraft body 11 can be combined by the cradle head 13, and the electric network can be inspected, whereby the inspection efficiency can be improved.

In some examples, guard 15 may be used to guard image detection device 14. In this case, the image detection device 14 in the grid inspection device 10 can be protected by the protection device 15.

Fig. 3 is a schematic view showing the structure of the inside of the damper device 12 according to the example of the present utility model.

In some examples, the shock absorbing device 12 may be used for shock absorption. As shown in fig. 3, in some examples, the shock absorbing device 12 may be disposed between the cradle head 13 and the aircraft body 11. In this case, the shaking of the aircraft body 11 caused by wind or erroneous operation during inspection can be reduced by the pan-tilt 13 and the damper 12, thereby affecting the operation of the image detection device 14, and thus the accuracy of inspection can be improved.

In some examples, the number of cushioning devices 12 may not be limited to one, i.e., the number of cushioning devices 12 may be a plurality, such as 2, 3, 4, 5, or more.

In some examples, the number of cushioning devices 12 is multiple. In some examples, a plurality of shock absorbing devices 12 may be distributed between the pan-tilt 13 and the aircraft body 11 in a preset manner. In this case, the deployment of the damper device 12 can be performed according to the weight of each component of the grid inspection apparatus 10, whereby the damper effect can be made more excellent while also facilitating the handling of the flight of the aircraft body 11. For example, the plurality of damping devices 12 may be uniformly distributed between the pan-tilt 13 and the aircraft body 11, so that the damping effect of each position between the pan-tilt 13 and the aircraft body 11 tends to be uniform to achieve better damping effect. For another example, the plurality of damper devices 12 may be distributed so that a vertical line in which the center of gravity of the three integrated bodies of the pan-tilt 13, the image detection device 14, and the guard device 15 is located coincides with a vertical line in which the center of gravity of the aircraft body 11 is located, whereby the weight of the aircraft body 11 can be balanced to control the flight.

Fig. 4 is an enlarged schematic view showing the structure of the region a in the damper device 12 according to the example of fig. 3. In fig. 4, some of the contents (e.g., the connection portion with the first mounting portion 121, and the portion connected with the pan/tilt head 13) have been omitted.

As shown in fig. 3 and 4, in some examples, the shock absorbing device 12 may include a first mounting portion 121, a compression bar 123, a compression plate 125, a shock absorbing mechanism, and a second mounting portion 122. In some examples, the first mount 121 may be connected with the aircraft body 11. In some examples, the compression bar 123 may be connected with the first mounting portion 121. In some examples, the pressure plate 125 may be coupled to the compression bar 123. In some examples, the shock absorbing mechanism may be coupled to the platen 125. In some examples, the second mount 122 may be coupled to a shock absorbing mechanism. In some examples, the second mount 122 may be connected to the pan/tilt head 13. In this case, the shake generated at the time of inspection of the aircraft body 11 can be transmitted to and absorbed in the shock absorbing mechanism through the pressing rod 123 and the pressing plate 125, and further the smoothness of the image detecting device 14 provided to the cradle head 13 is improved, thereby improving the accuracy of the inspection of the power grid.

In some examples, the first mounting portion 121 may be in the shape of a plate. In other examples, the first mounting portion 121 may also be a cover formed with a chamber accommodating the pressing rod 123, the pressing plate 125, the damper mechanism, and the second mounting portion 122.

As shown in fig. 4, in some examples, the second mounting portion 122 may form a chamber that houses the compression bar 123, the compression plate 125, and the shock absorbing mechanism. In this case, a stable structure can be formed, whereby the stability of the damper device 12 can be facilitated to be improved. In other examples, the second mounting portion 122 may also be in the shape of a plate, i.e., the second mounting portion 122 may not have the aforementioned chamber.

In some examples, the shock absorbing mechanism may include a resilient element 126, such as a spring, shock absorbing rubber, or the like. In some examples, the shock absorbing mechanism may also be a telescopic shock absorber 127, and the telescopic shock absorber 127 may also be a bumper, such as a memory metal bumper, a spring bumper, a magnetic bumper, a hydraulic bumper, or a pneumatic bumper, among others. In some examples, the number of elastic elements 126 and telescopic dampers 127 may not be limited to one, i.e., the number of elastic elements 126 and telescopic dampers 127 may be a plurality, such as 2, 3, 4, 5, or more. In this case, the vibration generated during inspection of the aircraft body 11 can be absorbed by the at least one elastic member 126 or the at least one telescopic damper 127, for example, the vibration is damped by the elastic member 126, and the rebound during the damping of the elastic member 126 is suppressed by the telescopic damper 127, so that the stability of the image detection device 14 provided to the cradle head 13 can be improved.

As shown in fig. 4, in some examples, the shock absorbing structure may also include a stop bar 124. In some examples, the stop bar 124 may be used to stop the resilient element 126 and match the number of resilient elements 126. In this case, the elastic member 126 can be secured at the position of the stopper rod 124, and the excessive swing amplitude of the elastic member 126 can be reduced during the shock absorption, thereby enhancing the shock absorption and shock absorbing effects.

The following continues the description of the guard 15 according to the utility model. Fig. 5 is a schematic diagram showing the cooperative installation of the image detection device 14 and the protection device 15 in the power grid inspection apparatus 10 according to the example of the present utility model. Fig. 6 is a schematic sectional view showing the protective device 15 according to the example of fig. 5.

As shown in fig. 5, in some examples, the guard 15 may include a guard portion 151 and a cleaning portion 152.

In some examples, the shielding portion 151 may be transparent, and in particular, the shielding portion 151 may be a member of transparent material or light-transmitting material, such as glass or transparent plastic, or the like. In this case, the image detection device 14 in the grid inspection apparatus 10 can still perform normal operation while being protected by the protecting portion 151.

In some examples, the guard 151 may be provided to the image detection device 14. In this case, the shielding portion 151 can be facilitated to shield the image detection device 14.

In some examples, the guard 151 may include a concave surface and a convex surface, and the concave and convex surfaces of the guard 151 may be opposite sides. In some examples, the concave surface of the shielding portion 151 may form an interior cavity 510, and the interior cavity 510 may be used to house at least a portion of the image detection device 14. In this case, at least a part of the image detection device 14 (for example, the key portion 141 such as a lens) is accommodated in the cavity 510 formed by the concave surface of the shielding portion 151, so that damage to the image detection device 14 due to dust or the like can be reduced.

For example, when the power grid inspection is performed in a region with a lot of dust, the power grid inspection device 10 is started or the weather environment is easy to cause wind dust, sand particles trapped in the wind dust are easy to wash the critical parts 141 such as the lens of the image detection device 14, so that permanent damage is caused, and in addition, the inspection cost is increased due to frequent replacement of such expensive parts, while the protection device 15 according to the present utility model accommodates the critical parts 141 such as the lens of the image detection device 14 in the inner cavity 510 formed by the concave surface of the protection part 151, so that the sand particles in the wind dust can be effectively blocked, and the protection device 15 is made of transparent or light-transmitting material, so that the cost is much lower than that of the lens of the image detection device 14, and therefore, the inspection cost can be frequently replaced, and the inspection cost can be indirectly reduced while the lens of the image detection device 14 is permanently protected.

In some examples, the convex surface of the guard 151 may have a flat surface that abuts against the critical portion 141 of the image detection device 14. In this case, the cleaning by the cleaning portion 152 can be facilitated later, and the situation that the image acquired by the image detecting device 14 is inaccurate after the formation of the cambered surface can be reduced.

In some examples, the guard 151 may be threadably disposed to the image detection device 14. In other examples, the protecting portion 151 may be further disposed on the image detecting device 14 by adhesion. In some examples, the interior cavity 510 of the shielding portion 151 and the image detection device 14 may form an enclosed space. In this case, the protection unit 151 can effectively block sand particles in the wind dust, and permanent damage of the sand particles to the critical portion 141 such as the lens of the image detection device 14 can be reduced.

As described above, the guard 15 may include the cleaning portion 152. As shown in fig. 5, in some examples, the cleaning portion 152 may be provided to the image detection device 14, and in particular, the cleaning portion 152 may be provided to the image detection device 14 by a link mechanism 153. In this case, the cleaning portion 152 can be facilitated to be close to the shielding portion 151, thereby facilitating the subsequent cleaning of the shielding portion 151 by the cleaning portion 152.

As shown in fig. 6, in some examples, the cleaning portion 152 may include a cleaning member 526 and a motor 522. In some examples, the motor 522 may be used to drive the cleaning member 526 to move in a convex-contacting manner. In this case, the guard 151 can be cleaned by the motor 522 and the cleaning tool 526, so that the guard 151 can be cleaned in time, and damage to at least a part of the image detection device 14 (for example, the key portion 141 such as a lens) due to direct contact with dust or the like can be reduced. In addition, the influence of the attachments such as water mist and dust on the operation of the image detection device 14 in the power grid inspection device 10 can be reduced by timely cleaning.

As shown in fig. 6, in some examples, the cleaning portion 152 may further include a housing 520, a screw 525, and an adjustment block 523.

In some examples, the housing 520 may be provided with the aforementioned motor 522. In this case, by providing the housing 520, structural support can be provided for the motor 522.

In some examples, housing 520 may have a recess 521. In some examples, the number of grooves 521 may be set to at least one, i.e., grooves 521 may be set to a plurality, e.g., 2, 3, 4, or more. In some examples, the length of the groove 521 is comparable to the screw 525. In some examples, the groove 521 may be a rectangular groove 521. In this case, the design of the groove 521 can facilitate the subsequent adjustment block 523 to be maintained stationary while being moved on the screw 525.

Fig. 7 is a schematic diagram showing the structure of the groove 521 and the adjustment block 523 according to an example of the present utility model. Fig. 8 is a schematic diagram showing the structure of the groove 521 and the adjustment block 523 according to another example of the present utility model. Fig. 9 is a schematic diagram showing the structure of the groove 521 and the adjustment block 523 according to still another example of the present utility model. It should be noted that fig. 7, 8 and 9 only show the portion of the adjusting block 523 that mates with the groove 521 according to the present utility model, for example, one end of the adjusting block 523 mates with one of the grooves 521 formed by the housing 520 to form the structure shown in fig. 7, 8 and 9, so it should be understood that the content shown in the drawings is not the entire content of the adjusting block 523 and the groove 521.

In some examples, the cavity of the groove 521 may be square, rectangular, rounded rectangular, spherical, ellipsoidal, polygonal, or a combination of figures, for example, rounded rectangular, ellipsoidal, and rectangular as shown in fig. 7-9. In some examples, the shape of the plurality of grooves 521 may be the same or different, and may not be limiting.

As shown in fig. 6-9, in some examples, the adjustment block 523 may be in the groove 521. Specifically, at least a portion of the adjustment block 523 is slidably engaged in the groove 521, for example, both ends of the adjustment block 523 are slidably engaged in the two grooves 521, respectively. In this case, when the adjustment block 523 moves relatively on the screw 525, the shake of the adjustment block 523 can be reduced by the rectangular groove 521, and thus the cleaning tool 526 that is interlocked with the adjustment block 523 can be kept stable when the convex surface of the guard 151 moves.

In some examples, the two ends of the adjustment block 523 may be square, rectangular, rounded rectangular, spherical, ellipsoidal, polygonal, or a block of a combined pattern that matches the shape of the groove 521, e.g., rounded rectangular, ellipsoidal, and rectangular as shown in fig. 7-9. In some examples, the grooves 521 may be filled with a lubricant. In this case, the movement of the adjustment block 523 can be made smoother and less shaky, whereby the smoothness of the cleaning piece 526 in conjunction with the adjustment block 523 when the convex surface of the shielding portion 151 moves can be improved. In some examples, the shape of the two ends of the adjustment block 523 may be the same or different, and this may not be limiting.

As shown in fig. 6, in some examples, screw 525 may be driven to rotate by motor 522. In some examples, the adjustment block 523 may be movable relative to the screw 525. In some examples, the adjustment block 523 may be threadably coupled with the screw 525. Specifically, the adjustment block 523 may be threadably coupled to the screw 525 in a manner that is movable relative to the screw 525, i.e., the adjustment block 523 may be threadably coupled to the screw 525 while also being movable relative to the screw 525. In some examples, the adjustment block 523 may be in linkage with the cleaning member 526. In this case, by the screw 525 that rotates together with the motor 522, the adjusting block 523 that is screwed to the screw 525 and is movable relatively, and the cleaning member 526 that is linked to the adjusting block 523 and is in contact with the convex surface of the protecting portion 151, when the protecting portion 151 is attached with water mist dust or the like, the screw 525, the adjusting block 523, and the cleaning member 526 can be driven by the start motor 522 to clean the protecting portion 151, whereby the influence of the attachment of the water mist dust or the like on the operation of the image detecting device 14 in the power grid inspection apparatus 10 can be reduced.

As shown in fig. 6, in some examples, the cleaning member 526 can have a rigid end 5261 and a flexible end 5262.

In some examples, the flexible end 5262 can have flexibility. In some examples, the flexible end 5262 can be used to contact a convex surface. In this case, by the flexible end 5262 of the cleaning member 526, the convex surface of the shielding portion 151 can be cleaned and the damage of the shielding portion 151, which may be caused by the rigid member contacting the convex surface of the shielding portion 151, can be reduced to affect the operation of the image detecting apparatus 14.

In some examples, the flexible end 5262 of the cleaning elements 526 are constructed of one of cotton, hemp, silk, wool, or synthetic fibers. In this case, the flexible end 5262 of the cleaning member 526 can have flexibility, and cleaning the convex surface of the shielding portion 151 by one of cotton, hemp, silk, wool, or synthetic fiber can reduce the damage of the shielding portion 151 caused by the rigid member contacting the convex surface of the shielding portion 151, which affects the operation of the image detecting device 14. For example, in order to clean mist and dust while reducing damage to the guard 151 during cleaning (e.g., improper cleaning of dust causing scratching), the present utility model preferably uses cleaning cotton (i.e., a nonwoven cotton material for cleaning) as the flexible end 5262 of the cleaning members 526.

As shown in fig. 6, in some examples, the rigid end 5261 of the cleaning member 526 is connected to the adjustment block 523 by a push rod 524. In this case, the flexible end 5262 of the cleaning member 526 can be driven by the push rod 524 and the adjusting block 523 to clean the convex surface of the protecting portion 151 through the rigid end 5261 of the cleaning member 526.

In some examples, the number of push rods 524 may not be limited to one, i.e., push rods 524 may be multiple. In this case, the stability of the cleaning member 526 in conjunction with the adjustment block 523 can be increased.

In some examples, the image detection device 14 may include at least one of a camera, a thermal imaging device. In some examples, at least a portion of image detection device 14 may be a lens of a camera or an objective lens of a thermal imaging device. In some examples, at least a portion of the image detection device 14 may be a lens of a camera and an objective lens of a thermal imaging device. In other words, the image detection device 14 may be a photographing device, a thermal imaging device, or a combination of both devices. In this case, the protection unit 151 can directly protect the critical portion 141 such as the lens of the photographing device or the objective lens of the thermal imaging device, thereby improving the lifetime of the lens of the photographing device or the objective lens of the thermal imaging device and reducing the inspection cost due to frequent replacement.

In some examples, the camera may be at least one of a camera or video camera.

In some examples, the thermal imaging device may be a thermal infrared imager.

In some examples, image detection device 14 may also be other devices having image detection functionality.

According to the utility model, the power grid inspection equipment 10 and the protection device 15 thereof can be provided, the image detection device 14 can be effectively and permanently protected during power grid inspection, and the stability of the image detection device 14 in the inspection process can be improved, so that the accuracy of power grid inspection is improved.

While the utility model has been described in detail in connection with the drawings and examples thereof, it should be understood that the foregoing description is not intended to limit the utility model in any way. Those skilled in the art can make modifications and variations to the present utility model as required without departing from the true spirit and scope of the utility model, and these modifications and variations fall within the scope of the utility model.
