Description

Technical Field

[0001] This utility model belongs to the field of power transmission technology, specifically relating to a suspension device for power transmission line auxiliary equipment based on a drone. Background Technology

[0002] Existing methods for installing warning lights on power transmission and distribution lines include using insulated operating rods for shorter lines and employing live-line working methods for taller lines, which are extremely risky, cumbersome, and inefficient. Using drones to install warning lights on power transmission and distribution lines avoids these risks, significantly improves efficiency, and is no longer affected by the height of the power lines or the terrain.

[0003] Traditional installation of warning lights on power transmission lines relies on manual live-line work or single-use drone mounting, which suffers from low efficiency, high risk, and high cost. While existing technologies such as insulated bucket trucks and drone-assisted mounting have improved upon this, they remain limited to single-light mounting, failing to meet the needs of large-scale warnings and exhibiting poor adaptability to complex terrain. For example, utility model patent 202111402123.4 discloses a drone-based high-altitude warning light mounting device. First, the short support leg of the warning light is inserted into the flared guide groove of the fixed arm, and the long support leg is inserted into the vertically downward-facing release groove of the release arm, with raised edges to prevent accidental detachment. Then, the warning light mounting base is installed onto the crossbeam of the drone mounting base via a connecting assembly. The drone mounting base supports... The side arm and isolation block are tied to the drone's legs. When the drone flies over the power transmission line, the power line contacts the warning light, generating downward pressure that causes the long leg to disengage from the trip slot. The two legs of the warning light then close and hook onto the power line under the action of elasticity. Finally, the drone moves down, and the short leg slides off the device from the horn-shaped guide groove, completing the safe mounting of the high-altitude warning light. However, the device only supports single-light mounting and cannot be expanded to a multi-light synchronous mounting structure. Long-distance operations require multiple round trips. The tripping relies on precise pressure from the wire. Strong winds or wire swaying can easily lead to tripping failure. Furthermore, the precision requirements for the protrusion of the trip slot are stringent, and reliability decreases after wear. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a suspension device for power transmission line auxiliary equipment based on drones, which has the advantages of easy installation and improved efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspension device for power transmission line auxiliary equipment based on unmanned aerial vehicles (UAVs), comprising an unmanned aerial vehicle (UAV) and auxiliary equipment. A hanger is suspended from the bottom of the UAV, and multiple buckles are fixedly connected to the bottom of the hanger. The buckles are used to suspend the auxiliary equipment, and the buckles will disengage from the auxiliary equipment after being resisted by the downward force of the power line.

[0006] The hanger includes a top fixing head and a bottom frame. The bottom outer wall of the fixing head is provided with a connecting groove, and the bottom outer side of the frame is engaged with a slot for a bolt-fixed buckle.

[0007] The auxiliary equipment includes symmetrical supports on both sides, with auxiliary devices fixedly connected to both sides of the supports. The auxiliary devices can also be bird deterrents, alarms, flashing lights, or warning lights. A latch is fixedly connected to the outer wall at the top center of the supports. The latch is unlocked when connected to the buckle and self-locked when disengaged.

[0008] The above technical solution can save installation time. The drone can carry four auxiliary devices at a time through the gantry. When the drone flies to the designated position, the latch on the auxiliary device hooks the bottom of the power line. Then, by pulling the power line upward by the drone, the latch can be released from the clip and self-locked at the moment of release, thus fixing the latch to the power line and fixing the auxiliary device to the power line.

[0009] Preferably, the bottom outer wall of the fixing head can also be a Y-shaped connecting groove, wherein the three connecting grooves of the Y shape are of equal length.

[0010] The above technical solution can change the number of lifting auxiliary equipment. Since the connecting groove is Y-shaped, three frames can be installed, so three auxiliary equipment can be lifted.

[0011] Preferably, the bottom outer wall of the fixing head can also be a cross-shaped connecting groove, wherein the four connecting grooves of the cross shape are of equal length.

[0012] The above technical solution can change the number of lifting auxiliary equipment. Since the connecting groove is cross-shaped, four frames can be installed, so four auxiliary equipment can be lifted.

[0013] Preferably, the bottom outer wall of the fixing head can also be a large-character-shaped connecting groove, wherein the five large-character-shaped connecting grooves are of equal length.

[0014] The above technical solution can change the number of lifting auxiliary equipment. Since the connecting groove is T-shaped, five frames can be installed, so five auxiliary equipment can be lifted.

[0015] Preferably, the bottom outer wall of the fixing head can also be a hexagonal connecting groove, wherein the six connecting grooves of the hexagon are of equal length.

[0016] The above technical solution can change the number of lifting auxiliary equipment. Since the connecting groove is hexagonal, six frames can be installed, thus enabling the lifting of six auxiliary equipment.

[0017] Preferably, the buckle includes a buckle block that engages with the hanger, the top of the buckle block is fixedly connected to a fixed hook, and the bottom of the buckle block is rotatably connected to a movable hook.

[0018] The above technical solution can achieve a fixing function. The fixed hook and the movable hook can clamp the buckle, thereby fixing the auxiliary equipment.

[0019] Preferably, the outer wall of the locking block is fixedly connected with a protrusion, and a rotating shaft for rotatable connection is connected in series between the locking block and the movable hook, with a cotter pin inserted into the inner wall of the rotating shaft.

[0020] The above technical solution can serve as a rotating pair. The locking block and the movable hook are connected by a rotating shaft, which allows the movable hook to rotate, thereby enabling it to be opened and released.

[0021] Preferably, the latch includes a V-shaped fixed base, a snap-fit ​​plate is rotatably connected to one outer wall of the fixed base, and a spring is fixedly connected at the connecting shaft between the fixed base and the snap-fit ​​plate.

[0022] The above technical solution can achieve the function of clamping. Since a spring is fixedly connected at the connecting shaft between the fixed base and the snap-fit ​​plate, after the buckle and the lock are disengaged, the spring will cause the snap-fit ​​plate to seal the top opening of the V-shaped fixed base, thereby allowing the lock to protect the wire.

[0023] Preferably, the top outer wall of the snap-fit ​​plate is fixedly connected with a plug, which is used to snap-fit ​​the fixing hook.

[0024] The above technical solution can serve as a limiting mechanism, allowing the insert block to be inserted into the fixing hook, thus mutually restricting each other and facilitating the locking mechanism for fixation.

[0025] Preferably, the outer wall of the fixed base away from the snap-fit ​​plate has a slot, the bottom outer wall of the fixed base is fixedly connected to a fixing foot, the back outer wall of the fixed base has a groove, and the bottom outer wall of the fixed base has a central groove located in the middle of the fixing foot.

[0026] The above technical solution can fix the buckle to the wire. The slot allows the snap-fit ​​plate to hold the wire more tightly, and the middle groove at the bottom makes it easier for the movable hook to make contact with the force, which facilitates the buckle to be fixed.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. The drone can carry four auxiliary devices at once via a gantry. When the drone reaches the designated location, it hooks the bottom of the power line with the latches on the auxiliary devices. By pulling the power line upwards, the latches disengage and self-lock instantly, thus securing the auxiliary devices to the power line. Four warning lights can be mounted simultaneously in a single flight, reducing takeoff and landing frequency by 75%, significantly saving battery and mechanical wear. The modular design facilitates maintenance and replacement, greatly improving the efficiency of long-distance line construction. The upward mounting mechanism allows the drone to operate away from the power line, completely avoiding the risks of separation jamming and electric shock. Simply fly the drone to the mounting position and then lift it upwards to complete the mounting process. The mounting process is simple and easy to operate; the drone does not need to fly directly above the power line, reducing the mounting risk in densely populated areas. The warning lights can be replaced with other devices, such as bird deterrents, alarms, and strobe lights, offering high expandability.

[0029] 2. Because the connecting slot is Y-shaped, three frames can be installed, allowing for the lifting of three auxiliary devices. Because the connecting slot is T-shaped, five frames can be installed, allowing for the lifting of five auxiliary devices. Because the connecting slot is hexagonal, six frames can be installed, allowing for the lifting of six auxiliary devices. Similar connecting slot structures can also be modified to accommodate 7 or 8 sets, enabling the lifting of more auxiliary devices in a single takeoff, demonstrating strong scalability.

[0048] In this embodiment, the lock 401 can be clamped by the fixed hook 301 and the movable hook 303, thereby fixing the auxiliary device 4. The locking block 300 and the movable hook 303 are connected by a rotating shaft 304, which allows the movable hook 303 to rotate, thereby opening and releasing it.

[0049] Example 4:

[0050] Please see Figures 3-6Based on Embodiments 1, 2, and 3, this utility model provides a technical solution: the latch 401 includes a V-shaped fixed base 4010, a snap-fit ​​plate 4011 is rotatably connected to one outer wall of the fixed base 4010, a spring 4015 is fixedly connected to the connecting shaft between the fixed base 4010 and the snap-fit ​​plate 4011, an insert block 4012 is fixedly connected to the top outer wall of the snap-fit ​​plate 4011, the insert block 4012 is used to snap-fit ​​the fixing hook 301, a slot 4014 is opened on the outer wall of the fixed base 4010 away from the snap-fit ​​plate 4011, a fixing foot 4013 is fixedly connected to the bottom outer wall of the fixed base 4010, a groove 4016 is opened on the back outer wall of the fixed base 4010, and an intermediate groove 4017 located in the middle of the fixing foot 4013 is opened on the bottom outer wall of the fixed base 4010.

[0051] In this embodiment, since a spring 4015 is fixedly connected to the connecting shaft between the fixed base 4010 and the snap-fit ​​plate 4011, after the snap-fit ​​3 is disengaged from the latch 401, the spring 4015 will cause the snap-fit ​​plate 4011 to seal the top opening of the V-shaped fixed base 4010, thereby allowing the latch 401 to hold the wire. The insert block 4012 can be inserted into the fixed hook 301, which can play a mutual restraining role, making it convenient for the latch 401 to be fixed, and allowing the snap-fit ​​plate 4011 to hold the wire more tightly. The middle groove 4017 at the bottom facilitates the contact of the movable hook 303, making it convenient for the latch 401 to be fixed.

[0052] The working principle and usage process of this utility model: The unmanned aerial vehicle (UAV) 1 can carry four auxiliary devices 4 at a time for takeoff via the jack 2. When the UAV 1 reaches the designated position, the latch 401 on the auxiliary device 4 hooks onto the bottom of the power line. Then, by pulling the power line upwards, the latch 401 disengages from the buckle 3 and self-locks at the moment of disengagement, thus fixing the latch 401 to the power line, thereby fixing the auxiliary device 4 to the power line. Since the connecting groove 201 is Y-shaped, three frames 202 can be installed, allowing for the lifting of three auxiliary devices 4. Since the connecting groove 201 is T-shaped, five frames 202 can be installed, allowing for the lifting of five auxiliary devices 4. Since the connecting groove 201 is hexagonal, six frames 202 can be installed, allowing for the lifting of six auxiliary devices 4. This is achieved by fixing the hook... The latch 301 and the movable hook 303 can clamp the lock 401, thereby fixing the auxiliary equipment 4. The locking block 300 and the movable hook 303 are connected by a rotating shaft 304, which allows the movable hook 303 to rotate and thus open and disengage. Since a spring 4015 is fixedly connected at the connecting shaft between the fixed base 4010 and the locking plate 4011, after the latch 3 disengages from the lock 401, the spring 4015 will cause the locking plate 4011 to seal the top opening of the V-shaped fixed base 4010, thus allowing the lock 401 to hold the wire. The insert block 4012 can be inserted into the fixed hook 301, which can play a mutual restraining role, making it easier for the lock 401 to be fixed and allowing the locking plate 4011 to hold the wire more tightly. The middle groove 4017 at the bottom facilitates the contact of the movable hook 303 with force, making it easier for the lock 401 to be fixed.
