Description

Technical Field

[0001] This application relates to the technical field of high-altitude cable snow removal equipment, and particularly relates to an unmanned aerial vehicle (UAV)-based high-altitude cable snow removal device. Background Art

[0002] In winter, the long-term covering and accumulation of ice and snow on high-altitude cables will cause an increased load on the iron towers supporting the high-voltage cables, which may lead to excessive stretching and breakage of the conductors, and even the collapse of the electric towers, seriously resulting in a large-scale power outage in the power system. Therefore, ice and snow covering on high-altitude cables in winter is a common natural disaster in the power system.

[0003] In the early stage, the main method used to remove ice and snow on cables was manual. This method required power workers to climb the tower to the cable, install a power construction hanging chair on the cable, and the construction personnel sat on the sliding chair and slid along the cable to remove ice and snow on the cable surface. Removing the snow on the cable surface in this way has low safety, high labor costs, and slow cleaning efficiency.

[0004] With the subsequent development of UAVs, in order to ensure the reliability of the power system, improve the efficiency of ice removal on high-voltage transmission lines, reduce losses, and safeguard the safety of maintenance workers, UAVs capable of removing snow on high-altitude lines have been developed. This is a method of using UAV technology to remove snow or ice on high-voltage transmission lines and communication cables. One common method in UAV snow removal is to tie an ice removal rod to the UAV. When the UAV flies to a position 1-2 meters away from the target cable and suddenly stops, the ice removal rod swings forward to hit the high-altitude cable to achieve the effect of snow and ice removal.

[0005] However, in many northern regions, the temperature in winter can often reach about -20°C, and rain and snow are likely to form a firm thick ice layer on high-altitude cables. Simply relying on the UAV to carry the ice removal rod to hit the cable to remove the ice and snow on the cable has an unsatisfactory effect. Utility Model Content

[0006] This application provides an unmanned aerial vehicle (UAV)-based high-altitude cable snow removal device, which can effectively solve the problems existing in the existing UAV snow removal equipment.

[0007] The above object of this application is achieved through the following technical solutions:

[0008] An unmanned aerial vehicle (UAV)-based high-altitude cable snow removal device includes a UAV main body with a main camera installed on the front side. The lower side of the UAV main body is connected with an ice removal rod through a binding rope;

[0009] On the lower side of the bottom plate of the UAV main body, a suspension is fixedly installed at each of the two ends along its length direction. There are two parallel suspension rods between the two suspensions, and the two ends of each suspension rod are fixedly connected to the two suspensions respectively;

[0010] A battery assembly and a hot air assembly are provided below the UAV body. The battery assembly can supply electrical energy to the hot air assembly, and the hot air assembly can blow hot air towards the front of the UAV body.

[0011] The upper sides of the battery assembly and the hot air assembly are respectively fixedly installed on the two suspension rods through a connecting member.

[0012] Further, the hot air assembly includes a first housing. Inside the first housing, two side-by-side high-speed blowers are installed. The housing of the high-speed blower is fixedly installed on the bottom plate of the first housing through a blower bracket. An outer side of the air outlet end of the high-speed blower is provided with a heating unit. An air outlet is provided on the front side of the first housing, and an air inlet is provided on the back of the first housing.

[0013] Further, the high-speed blower is obliquely arranged in the first housing, and the position of its air inlet end is higher than the position of its air outlet end. Correspondingly, the air outlet facing the air outlet end of the high-speed blower is located lower on the front panel of the first housing.

[0014] Further, the heating unit includes two symmetrically arranged heating rods. A support frame is provided between the two heating rods. The wiring ends of the two heating rods are fixedly installed on the support frame, and the lower end of the support frame is fixedly installed on the bottom plate of the first housing.

[0015] Further, the battery assembly includes a second housing. A rechargeable battery is installed in the second housing. After the rechargeable battery in the second housing is electrically connected to the high-speed blower and the heating rods, the rechargeable battery can supply electrical energy to the high-speed blower and the heating rods.

[0016] Further, the connecting member includes two clamping hooks. The two clamping hooks are respectively fixedly installed on the two suspension rods. The lower ends of the two clamping hooks are fixedly connected through a common mounting frame. The middle position of the lower end of the mounting frame is fixedly connected to the top of the first housing or the second housing through a connecting shaft.

[0017] Further, the overall weights of the battery assembly and the hot air assembly are close, and the battery assembly and the hot air assembly are centrosymmetric about the center of the UAV body below the UAV body.

[0018] Further, the binding rope includes two horizontal ropes and one vertical rope. The mutually remote ends of the two horizontal ropes are respectively installed at the middle positions of two legs on the lower side of the drone body through a first metal ring. The mutually close ends of the two horizontal ropes are fixedly connected to the same second metal ring. The upper end of the vertical rope is also connected to the second metal ring, and the lower end of the vertical rope is fixedly tied to the upper end of the ice removal rod.

[0019] Further, a rain shield is fixedly installed above each of the two air outlets on the front side of the second housing.

[0020] Further, an auxiliary camera is respectively installed on both sides of the bottom plate of the drone body.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] When the drone body of the present application performs ice and snow removal operations on high-altitude cables, it can first use the ice removal rod on the lower side of the drone body to impact the cable to knock down the snow and ice layers that are not firmly solidified on the high-altitude cable. At this time, the solid ice layers that cannot be directly knocked down by the ice removal rod on the high-altitude cable will also be exposed. At this time, the power maintenance staff can start the hot air component below the drone body and use the hot air generated by the hot air component to heat these ice blocks on the high-altitude cable. Under the baking of the hot air, these solid ice layers on the high-altitude cable will gradually melt and become loose on the cable. At this time, control the drone body to use the ice removal rod below to knock the high-altitude cable again, and these originally solid ice layers on the cable will be easily peeled off. Therefore, compared with the prior art, the snow removal device of the present application can efficiently remove even the stubborn ice layers generated due to low temperature on the high-altitude cable by cooperating the hot air component and the ice removal rod.

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0031] As Figure 1 and Figure 2 shown, a high-altitude cable snow removal device based on a drone disclosed in the present application includes a drone body 2 with a main camera 1 installed on the front side. A deicing rod 4 is connected to the lower side of the drone body 2 through a binding rope 3; two suspensions 5 are respectively and fixedly installed at both ends of the lower side of the bottom plate of the drone body 2 along its length direction. Two mutually parallel suspension rods 6 are provided between the two suspensions 5, and both ends of the suspension rods 6 are fixedly connected to the two suspensions 5 respectively; a battery assembly 7 and a hot air assembly 8 are provided below the drone body 2. The battery assembly 7 can supply electric energy to the hot air assembly 8, and the hot air assembly 8 can blow hot air towards the front of the drone body 2; the upper sides of the battery assembly 7 and the hot air assembly 8 are respectively and fixedly installed on the two suspension rods 6 through a connecting member 9.

[0032] In the above embodiments, the bottom plate of the UAV body 2 of the present application fixes the battery assembly 7 and the hot air assembly 8 on the UAV body 2 through two suspension rods 6 and a connecting member 9. In this way, when the UAV body 2 flies using the propellers around it, the battery assembly 7 and the hot air assembly 8 can move together. The de-icing rod 4 installed under the UAV body 2 of the present application through the binding rope 3 is the same as that in the prior art, which is a strip-shaped rod made of rubber material. When the UAV body 2 flies to the cable to be cleaned and suddenly stops, the de-icing rod 4 will swing towards the high-altitude cable to be cleaned under the action of inertia, and when they come into contact, the impact force of the de-icing rod 4 will shake off the ice and snow attached to the high-altitude cable.

[0033] However, in the cold north, ice and snow often form a certain thickness of solid ice layer on the cable. This part of the ice layer not only has high strength but also is firmly wrapped around the cable. If only relying on the inertia of the de-icing rod 4 on the UAV body 2 to strike the cable, it is very difficult to peel off these solid ice layers from the cable. As time accumulates, the thickness of this part of the solid ice layer may continue to increase. If it is not effectively treated all the time, there is still a risk of damage to the power system.

[0034] The hot air assembly 8 arranged under the UAV body 2 of the present application can obtain electrical energy from the battery assembly 7 after being started, and convert the electrical energy into heat energy and release it along with the flowing air, so as to form hot air in front of the UAV body 2. After these hot air contacts the solid ice layer on the cable, it will quickly exchange heat with these ice layers and play a role in heating them. The heated ice will gradually melt and become loose on the cable. At this time, control the UAV body 2 to use the de-icing rod 4 below to strike the high-altitude cable again, and these originally solid ice layers on the cable will be easily peeled off. The applicable range and effect of the present application in actual use are significantly better than those of the prior art. Compared with the prior art, the present application can not only use the de-icing rod 4 to remove ordinary ice and snow on the high-altitude cable, but also cooperate with the hot air assembly 8 and the de-icing rod 4 to efficiently remove the solid ice layer formed on the high-altitude cable due to low temperature.

[0035] Further, as Figure 1 、 Figure 3 、 Figure 4 and Figure 5 shown, the hot air assembly 8 includes a first housing 81. Inside the first housing 81, two side-by-side high-speed blowers 82 are installed. The housing of the high-speed blower 82 is fixedly installed on the bottom plate of the first housing 81 through a blower bracket 83. An air heating unit 84 is arranged outside the air outlet end of the high-speed blower 82; an air outlet 85 is arranged on the front side of the first housing 81, and an air inlet 86 is arranged on the back of the first housing 81.

[0036] In the above embodiments, when the two high-speed blowers 82 arranged side by side in the first housing 81 are working, they may generate an air flow with a certain width in front of the UAV body 2 through the air outlet 85 on the front side of the first housing 81. Compared with a single high-speed blower 82, it can not only increase the air volume but also expand the purging range. The heating unit 84 is arranged outside the air outlet ends of the two high-speed blowers 82, so that the air blown out by the high-speed blowers 82 will be heated when passing through the heating unit 84, thereby generating hot air. After these hot air are blown out from the air outlet 85 of the first housing 81 and come into contact with the stubborn ice layer on the high-altitude cable, they can play a very good heating role on these ice layers. The air inlet 86 on the back of the first housing 81 can continuously transport external air into the first housing 81 when the high-speed blower 82 is working.

[0037] Further, as Figure 4 and Figure 5 shown, the high-speed blower 82 is inclined in the first housing 81, and the position of its air inlet end is higher than that of its air outlet end. Correspondingly, the air outlet 85 facing the air outlet end of the high-speed blower 82 is located lower on the front panel of the first housing 81.

[0038] In the above embodiments, when the high-speed blower 82 of the present application is arranged in the first housing 81 in the above manner, when hot air needs to be blown on the high-altitude cable, the worker can fly the UAV body 2 above the high-altitude cable. In this way, the safety distance between the propeller of the UAV and the high-altitude cable can be effectively increased, reducing the risk of contact between the propeller and the high-altitude cable during the snow removal process. In addition, during the flight of the UAV body 2, the ice-breaking rod 4 is suspended below it by a tying rope 3, and the air blown out by the high-speed blower 82 is also inclined downward. Therefore, during snow removal, after the worker adjusts the position of the UAV body 2 above the high-altitude cable (aligning the striking part of the ice-breaking rod 4 with the high-altitude cable), only by moving the UAV body 2 horizontally, the ice-breaking rod 4 can be directly used to strike the high-altitude cable after the hot air has treated the high-altitude cable, without the need to adjust the position of the UAV body 2 in the vertical direction as in the case where the air outlet end of the high-speed blower 82 is horizontally arranged, effectively improving the operation efficiency.

[0039] Further, as Figure 5 shown, the heating unit 84 includes two symmetrically arranged heating rods 841. A support frame 842 is provided between the two heating rods 841. The wiring ends of the two heating rods 841 are fixedly installed on the support frame 842, and the lower end of the support frame 842 is fixedly installed on the bottom plate of the first housing 81.

[0040] In the above embodiments, the support frame 842 of the present application can provide an installation basis for two heating rods 841 through the first housing 81. And during actual use, part of the wiring of the heating rods 841 and the battery assembly 7 can also be arranged in the support frame 842, so that the interior of the first housing 81 is more regular and concise, and it can also avoid the airflow disturbance generated when the high-speed fan 82 works from disturbing the connecting wires for powering the heating rods 841.

[0041] Further, as Figure 3 shown, the battery assembly 7 includes a second housing 71. A rechargeable battery 72 is installed in the second housing 71. After the rechargeable battery 72 in the second housing 71 is electrically connected to the high-speed fan 82 and the heating rods 841, the rechargeable battery 72 can provide electrical energy for the high-speed fan 82 and the heating rods 841.

[0042] In the above embodiments, the rechargeable battery 72 in the second housing 71 can separately provide electrical energy for the high-speed fan 82 and the heating rods 841, so that they can operate at any time when needed. And when the rechargeable battery 72 is used next time, it only needs to be fully charged, which improves the convenience of the present application.

[0043] Further, as Figure 1 and Figure 3 shown, the connecting member 9 includes two clamping hooks 91. The two clamping hooks 91 are respectively fixedly installed on two suspension rods 6. The lower ends of the two clamping hooks 91 are fixedly connected through a common mounting frame 92. The middle position at the lower end of the mounting frame 92 is fixedly connected to the top of the first housing 81 or the second housing 71 through a connecting shaft 93.

[0044] In the above embodiments, the mounting frame 92 is fixedly installed on the two suspension rods 6 through the two clamping hooks 91. In this way, the connecting shaft 93 at the center of the lower end of the mounting frame 92 can provide a uniform pulling force on the lower first housing 81 and second housing 71 through the suspension rods 6, ensuring that during the flight of the drone body 2, the structural members in the first housing 81 or the second housing 71 can move forward together with the drone body 2.

[0045] Further, as Figure 1 shown, the overall weights of the battery assembly 7 and the hot air assembly 8 are close, and the battery assembly 7 and the hot air assembly 8 are symmetric about the center of the drone body 2 below the drone body 2.

[0046] In the above embodiments, the battery assembly 7 and the hot air assembly 8 are arranged in the above manner, which can make the drone body 2 have a balanced force during flight, fly smoothly, and also facilitate the electric power maintenance workers to control the drone body 2.

[0047] Further, as Figure 1 and Figure 2As shown in the figure, the tying rope 3 includes two horizontal ropes 31 and one vertical rope 32. The mutually remote ends of the two horizontal ropes 31 are respectively installed at the middle positions of the two legs on the lower side of the UAV body 2 through a first metal ring 33. The mutually close ends of the two horizontal ropes 31 are fixedly connected to the same second metal ring 34. The upper end of the vertical rope 32 is also connected to the second metal ring 34. The lower end of the vertical rope 32 is fixedly tied to the upper end of the ice removal rod 4.

[0048] In the above embodiments, when the mutually close ends of the two horizontal ropes 31 with equal lengths suspend the vertical rope 32 in the air through the second metal ring 34, under the gravity of the ice removal rod 4 at the lower end of the vertical rope 32, the vertical rope 32 and the ice removal rod 4 will be in the middle area under the lower side of the UAV body 2 under the restriction and traction of the two horizontal ropes 31. In this way, when the UAV body 2 is flying, it can stably fly with the ice removal rod 4.

[0049] Furthermore, as Figure 1 and Figure 4 shown in the figure, a rain shield 10 is fixedly installed above the two air outlets 85 on the front side of the second housing 71.

[0050] In the above embodiments, when snow falls during the operation of the UAV body 2, the rain shield 10 on the air outlet 85 can prevent snowflakes from floating into the first housing 81.

[0051] Furthermore, as Figure 4 and Figure 5 shown in the figure, an auxiliary camera 11 is respectively installed on both sides of the bottom plate of the UAV body 2.

[0052] In the above embodiments, the auxiliary cameras 11 installed on both sides of the bottom plate of the UAV body 2 cooperate with the main camera 1 on the front side of the UAV body 2, which can facilitate the power maintenance workers to have a broader perspective to observe the real-time cleaning situation of the high-altitude cables.

[0053] The implementation principle of this embodiment is as follows: After the power maintenance workers determine the high-altitude cables that need to be cleaned, they start the UAV body 2. First, use the ice removal rod 4 under the UAV body 2 to impact the cables to knock down the snow and ice layers that are not firmly solidified on the high-altitude cables. At this time, the solid ice layers that cannot be directly knocked down by the ice removal rod 4 on the high-altitude cables will also be exposed. Then, the power maintenance staff can start the high-speed fan 82 and the heating rod 841 in the hot air component 8 under the UAV body 2, and use the hot air generated by the hot air component 8 to heat these ice blocks on the high-altitude cables. Under the baking of the hot air, these solid ice layers on the high-altitude cables will gradually melt and become loose on the cables. At this time, control the UAV body 2 to use the ice removal rod 4 under it to knock the high-altitude cables again, and these originally solid ice layers on the cables will be easily peeled off, thus comprehensively completing the cleaning work of the high-altitude cables.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
