Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to an auxiliary device for high-altitude installation of power cables and a use method thereof. Background Art

[0002] Currently, when laying cables at high altitudes, due to the heavy weight of the cables themselves, drones are usually used to move thinner guide ropes, which are then pulled to the location of workers on the tower. The guide ropes are then connected to winches at both ends of the cable laying line to gradually pull larger guide ropes until the guide ropes can bear the weight of the cables, thereby assisting in the high-altitude laying of the cables.

[0003] A Chinese patent with publication number CN104332894B discloses a UAV-mounted pay-off stand and a UAV. The problem raised in the background technology is that when the UAV is stationary or hovering in the air, the pay-off stand still pays out the wire, which will cause the initial guide rope released by the pay-off stand to interfere with the flight of the UAV.

[0004] Based on the existing technology, there are the following problems:

[0005] In the prior art, when a guide rope is pulled by a drone to assist in the installation of cables at high altitude, the end of the pulling rope is usually directly connected and fixed to the bottom of the drone, and then the guide rope is driven to move by the drone. However, since drones are usually used in wild forests to assist in the installation of cables at high altitude, they are often affected by strong air currents, and the drone may fall and be damaged. Although the staff uses the method of cutting the guide rope to reduce the probability of the drone crashing, the staff can only cut the guide rope from a position close to the winch, which is less effective in rescuing the drone and affects the efficiency of subsequent cable installation. Referring to the above application documents, it only controls the start or pause of the guide rope release when the drone is in a hovering state. There is no remedial measure for the situation of strong air currents encountered during the release process, which has certain shortcomings. In order to solve the above problems, an auxiliary device for the high-altitude installation of power cables and a method for using the same are proposed. Summary of the invention

[0034] S2: When the guide rope is moving and an accident occurs due to strong airflow, the clamping block assembly is separated from the clamping assembly to drop the guide rope.

[0035] The present invention provides an auxiliary device for high-altitude installation of power cables and a method for using the same. Compared with the prior art, the device has the following beneficial effects:

[0036] 1. The present invention facilitates the control of the connection or disconnection of the guide rope with the drone through the cooperation of the card block assembly and the card connection assembly, so that the drone can drive the guide rope to move to a specified position to assist in the use of high-altitude cable erection, and it is convenient to throw the guide rope down to separate it from the drone, so that when the drone encounters strong airflow, the guide rope can be separated from the drone, which is convenient for maintaining the stability of the drone and avoiding affecting the subsequent use of auxiliary cable erection. Moreover, through the extrusion assembly and the limit shell, the card block assembly and the guide rope have downward elastic potential energy when separated, so that the guide rope can be quickly separated from the drone.

[0037] 2. The step structure formed by the limit block and the clamping rod of the present invention is adapted to the bending part of the limit claw, and the first arc surface and the first plane are adapted to the second arc surface and the second plane respectively, so that the limit claw is conveniently separated from the limit block, and the limit claw and the limit block are conveniently connected to each other more fully, thereby improving the stability of the connection, and the stability of the connection between the limit claw and the limit block is further improved by the limit assembly;

[0038] The spring is used to keep the end of the limit claw away from the second arc surface in the tendency to rotate upward, so as to prevent the gravity of the limit shell itself from affecting the limiting effect of the limit claw on the limit block. When the guide rope moves with the flight of the drone, the guide rope pulls the limit block downward, so that the limit block and the limit claw are stably engaged. By setting the limit inclined surface, the upward rotation angle of the limit claw is limited, thereby ensuring the stability of the engagement between the limit claw and the limit block when the guide rope moves with the drone.

[0039] 3. The present invention drives the limit shell to move through the driving component, so that the card assembly arranged in a ring array is separated from the limit block during synchronization, so as to put down the guide rope or connect the guide rope, and the limit shell is moved by the connecting component while driving the extrusion component to move, so as to provide downward elastic potential energy to the limit block by squeezing the first spring, thereby facilitating the limit block to quickly detach from the mounting shell, so as to facilitate the guide rope to quickly move away from the drone, reducing the probability of the guide rope being entangled on the drone due to wind after being thrown down.

[0040] 4. The present invention facilitates fixing of the guide rope through the fixing assembly, reduces the probability of disconnection of the connection position of the guide rope during the movement of the drone, facilitates stable movement of the guide rope, and is convenient for subsequent cable installation and use. At the same time, the fixing assembly and the like are thrown down together with the guide rope, so that the end of the thrown guide rope has a certain weight, further increases the speed of throwing down the guide rope, and reduces the probability of the guide rope being entangled on the drone due to wind after being thrown down;

[0041] By means of mounting parts, mounting sleeves and fixing components, the guide rope is fixed at the bottom of the UAV landing gear, thereby reducing the probability of the guide rope being entangled on the UAV during the movement of the guide rope with the UAV, thereby avoiding affecting the subsequent throwing of the guide rope to the designated position and improving the stability of the subsequent cable installation.

[0069] See also Fig.10 and Fig.12 , the card block assembly 28 includes:

[0070] A limit block 281, a clamping rod 282 is fixedly provided at the bottom of the limit block 281, a fixing assembly 29 for fixing the guide rope is provided at the bottom of the clamping rod 282, the side wall diameter of the limit block 281 is larger than the side wall diameter of the clamping rod 282, so as to form a step structure at the connection between the limit block 281 and the clamping rod 282, and a first arc surface 283 and a first plane 284 are provided at the bottom of the limit block 281;

[0071] See also Fig.11 , Fig.13 and Fig.15 , the card assembly 20 includes:

[0072] The limiting claw 201 is rotatably disposed on the side wall of the mounting shell 24 and extends into the mounting shell 24. The side of the limiting claw 201 located in the mounting shell 24 is designed to be bent and is adapted to the step structure formed by the limiting block 281 and the clamping rod 282. The bending part of the limiting claw 201 is provided with a second arc surface 203 and a second plane 202 respectively adapted to the first arc surface 283 and the first plane 284.

[0073] The clamping assembly 20 further includes:

[0074] The clamping groove 206 is provided on the side wall of the mounting shell 24 for sleeve-mounting the limit claw 201. The inner wall of the clamping groove 206 is provided with a limit inclined surface 207 for limiting the limit claw 201 from excessively rotating upward. The inner walls of both sides of the clamping groove 206 are provided with a first groove. The inner wall of the first groove is rotatably provided with a rotating rod 204, and the middle end of the side wall of the rotating rod 204 is fixedly sleeved on the lower end of the side wall of the limit claw 201. The inner wall of the first groove is fixedly sleeved with a mounting ring. The inner wall of the mounting ring is provided with a spring 205, and the two ends of the spring 205 are respectively fixedly connected to the side wall of the rotating rod 204 and the inner wall of the mounting ring. , so that the end of the limiting claw 201 away from the second arc surface 203 maintains a tendency to rotate upward, thereby the limiting block 281 is clamped and limited by the limiting claw 201, and a limiting shell 22 for pushing the limiting claw 201 to rotate is provided on the outer side of the connecting component 26, so that the end of the limiting claw 201 away from the second arc surface 203 rotates downward, thereby separating the limiting claw 201 from the limiting block 281, and the inner wall of the limiting shell 22 is slidably connected to the outer wall of the mounting shell 24, and a driving component 25 for driving the limiting shell 22 to move is provided on the outer side of the connecting component 26 and at the top of the limiting shell 22.

[0075] The bottoms of the mounting shell 24 and the limiting shell 22 are both designed to be open. A through hole for sleeve-mounting the first rod body 271 is provided at the top of the mounting shell 24, and the through hole is communicated with the inner wall of the mounting shell 24. The inner wall diameter of the through hole is smaller than the inner wall diameter of the mounting shell 24, so as to limit the movement of the pressure plate 274 and prevent the pressure plate 274 from being separated from the mounting shell 24, thereby limiting the position of the second rod body 273. When the limiting shell 22 is at the top, the bottom of the limiting shell 22 is located on the inner side of the limiting claw 201, so as to facilitate the limiting claw 201 to rotate when the limiting shell 22 moves;

[0076] The outer wall of the mounting shell 24 and the position staggered with the clamping groove 206 are provided with a second slide groove 23 arranged in a circular array, and the second slide groove 23 is provided with a second slider inside, and the second slider is fixedly connected to the inner wall of the limiting shell 22 to improve the stability of the movement of the limiting shell 22;

[0077] The first arc surface 283 is located outside the first plane 284 , and the second arc surface 203 is located outside the second plane 202 .

[0078] In a specific implementation, when it is necessary to separate the limiting block 281 from the limiting claw 201 to drop the fixing assembly 29 and the guide rope, the limiting claw 201 is rotated downward, so that the limiting claw 201 drives the rotating rod 204 to overcome the elastic force of the spring 205 and rotate downward along the clamping groove 206, that is, the end of the limiting claw 201 close to the second arc surface 203 is rotated upward, so that the limiting claw 201 is separated from the limiting block 281, so that the limiting block 281 is separated from the mounting shell 24, so as to facilitate dropping the guide rope;

[0079] By forming a step structure at the connection between the limiting block 281 and the clamping rod 282, and the step structure is adapted to the bending part of the limiting claw 201, it is convenient for the limiting claw 201 to clamp the limiting block 281. When the limiting claw 201 rotates upward at one end close to the second arc surface 203, the limiting block 281 is driven to move upward, so as to facilitate the separation of the limiting block 281 from the limiting claw 201. In this process, the second arc surface 203 contacts the first plane 284 and the first arc surface 283 in turn. By setting the second arc surface 203 and the first arc surface 283, it is convenient for the limiting claw 201 to separate from the limiting block 281. By setting the first plane 284 and the second plane 202, the limiting claw 201 can be more fully in contact with the limiting block 272 when clamped, thereby improving the stability of the clamping.

[0080] The spring 205 is used to keep the end of the limiting claw 201 away from the second arc surface 203 in an upward rotational trend, so as to facilitate the clamping and limiting of the limiting block 281, and to prevent the gravity of the limiting shell 22 itself from affecting the limiting of the limiting block 281 by the limiting claw 201. Since the fixing component 29 is arranged at the bottom of the limiting block 281, when the guide rope moves with the UAV 1 in flight, the guide rope pulls the limiting block 281 downward, so that the limiting block 281 is stably clamped with the limiting claw 201, and the limiting inclined surface 207 is provided to limit the upward rotation angle of the limiting claw 201, so as to ensure the stability of the clamping of the limiting claw 201 with the limiting block 281 when the guide rope moves with the UAV 1.

[0081] The clamping components 20 arranged in a ring array are provided to limit the position of the limiting clamping block 281, thereby improving the stability of the clamping.

[0082] See also Figure 6 and Figure 7 , the connection component 26 includes:

[0083] The mounting sleeve 261 is fixedly arranged at the bottom of the mounting member 21, and the bottom of the mounting sleeve 261 is fixedly connected to the top of the mounting shell 24. The side wall of the mounting sleeve 261 is provided with movable through grooves arranged in a circular array, and the inner walls of the movable through grooves are sleeved with movable rods 262. The ends of the movable rods 262 that are away from each other are fixedly connected to the upper end of the limit shell 22, and the ends of the movable rods 262 that are close to each other are provided with an extrusion component 27 for extruding the limit block 281.

[0084] In a specific implementation, the installation sleeve 261 is used to facilitate the connection between the mounting member 21 and the mounting shell 24, thereby ensuring the stability of the snap-in assembly 20 and the block assembly 28, and the moving through groove and the moving rod 262 enable the limit shell 22 to drive the extrusion assembly 27 to move when it moves, so that when the limit shell 22 drives the limit claw 201 to rotate, the second spring is squeezed through the extrusion assembly 27 to provide downward elastic potential energy to the limit block 281, thereby facilitating the limit block 281 to be quickly thrown off after the limit block 281 is separated from the limit claw 201.

[0085] See also Figure 4 and Figure 5 , the driving assembly 25 comprises:

[0086] The mounting seat 251 is fixedly sleeved on the outer wall of the mounting sleeve 261 and is located at the top of the limiting shell 22. The bottom of the mounting seat 251 and the top of the limiting shell 22 are respectively fixed with a first electromagnet 252 and a second electromagnet 253;

[0087] The mounting cover 254 is fixedly sleeved on the outer side of the mounting seat 251 , and the inner wall of the mounting cover 254 is located on the outer side of the limiting shell 22 , so as to shield the mounting seat 251 and the limiting shell 22 .

[0088] In a specific implementation, the first electromagnet 252 and the second electromagnet 253 are powered, and the side where the first electromagnet 252 and the second electromagnet 253 are close to each other is the same pole, so that the repulsive force generated drives the second electromagnet 253 and the limiting shell 22 to move downward, so that the limiting shell 22 rotates the limiting claws 201 arranged in a circular array, so that the limiting claws 201 arranged in a circular array are synchronously separated from the limiting block 281;

[0089] By providing the mounting cover 254, the mounting seat 251 and the limiting shell 22 are shielded, thereby reducing the influence of external factors on the stability of the first electromagnet 252 and the second electromagnet 253.

[0091] The first rod body 271 is fixedly arranged at one end of the moving rod 262 which is close to each other, and is sleeved on the inner wall of the mounting sleeve 261. A limiting groove is provided at the bottom of the first rod body 271. The inner wall of the limiting groove is sleeved with a second rod body 273 and a limiting block 272. The second rod body 273 and the limiting block 272 are fixedly connected on one side which is close to each other. One end of the second rod body 273 which is away from the limiting block 272 extends to the bottom of the first rod body 271.

A second spring is fixedly provided at the bottom of the pressure plate 274 to elastically support the top of the limiting block 281. A space is left between the bottom of the pressure plate 274 and the top of the limiting block 281 for the limiting block 281 to move upward.

[0094] In a specific implementation, when the limiting shell 22 moves downward, it drives the moving rod 262 to move along the moving through slot, thereby driving the first rod body 271 to move along the inner wall of the mounting sleeve 261, and the first rod body 271 drives the second rod body 273 and the pressure plate 274 to move, so that the pressure plate 274 squeezes the first spring, so that after the limiting shell 22 drives the limiting claw 201 to rotate and separate from the limiting block 281, under the elastic potential energy of the first spring, the limiting block 281 and the clamping rod 282 quickly disengage from the mounting shell 24, so as to facilitate the rapid dropping of the guide rope, so that the end of the guide rope close to the drone 1 quickly moves away from the drone 1, and the guide rope is prevented from being entangled with the drone 1;

[0095] The limiting block 272 and the second rod 273 move in the limiting groove. When the first rod 271 moves with the limiting housing 22, the second rod 273 has a certain moving space in the limiting groove, so as to avoid the first rod 271 pressing against the limiting block 281 after the limiting claw 201 is not rotated to a specified degree by the limiting housing 22, that is, after the limiting claw 201 is separated from the limiting block 281, thereby hindering the movement of the limiting block 281 and preventing the limiting block 281 from being separated from the limiting claw 201.

[0096] By limiting the movement of the second rod 273 by the limiting block 272, the second rod 273 is prevented from being separated from the first rod 271, which is convenient for practical use. At the same time, a first spring is provided to facilitate the reset of the second rod 273 and to provide downward elastic potential energy to the second rod 273, which is conducive to increasing the speed of separating the limiting block 281 from the mounting shell 24.

[0097] By leaving a space between the bottom of the pressure plate 274 and the top of the limiting block 281 for the limiting block 281 to move upward, when the limiting claw 201 rotates and separates from the limiting block 281, the limiting claw 201 drives the limiting block 281 to move upward, so that the limiting claw 201 and the limiting block 281 are separated. When the limiting block 281 is installed in the installation shell 24, the limiting claw 201 is first rotated to a position separated from the limiting block 281, and then the limiting block 281 is inserted into the installation shell 24, and the bottom of the limiting block 281 is located at the top of the limiting claw 201. Then, the limiting claw 201 is released, that is, the limiting claw 201 is clamped and fixed to the limiting block 281;

[0098] The first sliding groove 275 and the first sliding block limit the movement of the pressure plate 274 to improve the stability of the movement of the pressure plate 274 and facilitate improving the stability of the first spring.

[0099] Example 2: Please refer to Fig.14 The technical solution of this embodiment is different from that of the first embodiment in that the fixing assembly 29 includes:

[0100] The fixing frame 2901 is fixedly arranged at the bottom of the clamping rod 282 and is made of elastic metal material. The side wall of the clamping rod 282 is provided with a limiting component 291 for limiting the fixing component 29:

[0101] The fixing rod 2905 is fixed to the inner side of the fixing frame 2901 by bolts, and the fixing seats 2902 are fixed to both ends of the fixing rod 2905, and the side wall diameter of the fixing seat 2902 is larger than the side wall diameter of the fixing rod 2905, so as to prevent the fixing rod 2905 from being separated from both sides of the fixing frame 2901 after the fixing frame 2901 has fixed the fixing rod 2905;

[0102] The tie-down drum 2904 is fixed on the inner side of the fixing seat 2902 at one end of the fixing rod 2905, and is used to fix the guide rope. The center points of the tie-down drum 2904, the fixing seat 2902 and the fixing rod 2905 are on the same straight line, and the center of the side walls of the tie-down drum 2904, the fixing seat 2902 and the fixing rod 2905 are all provided with wire holes 2903. After the block assembly 28 is embedded in the mounting shell 24 through the mounting member 21, the connecting assembly 26 and the mounting shell 24, the position where the fixing assembly 29 fixes the guide rope is located at the bottom of the landing gear of the UAV 1.

[0103] In the specific implementation, the guide rope is passed through the wire hole 2903 and tied to the tie plate 2904, so that the guide rope is connected and fixed to the fixing rod 2905 and the fixing seat 2902. Then, the fixing rod 2905 is fixed to the inner side of the fixing frame 2901 by bolts to connect the guide rope to the clamping rod 282, so that the drone 1 can drive the guide rope to move;

[0104] By making the side wall diameter of the fixing seat 2902 larger than the side wall diameter of the fixing rod 2905, after the fixing rod 2905 is fixed to the fixing frame 2901, the fixing seat 2902 is located on both sides of the fixing frame 2901, thereby preventing the fixing rod 2905 from being separated from the fixing frame 2901, thereby improving the stability of the fixing guide rope;

[0105] Since the guide rope towed by the drone 1 is usually thin, in order to avoid the guide rope and the fixing seat 2902 from being disconnected due to friction during flight, the fixing seat 2902 and the fixing rod 2905 can be made of rubber material, and the fixing frame 2901 can be made of elastic metal material, so that under the action of the bolt, the fixing frame 2901 squeezes and fixes the fixing rod 2905, and the stability of the guide rope connection is ensured by the limit of the fixing seat 2902. It is better to use an elastic metal material that can be deformed but not stretched to avoid affecting the stability of the fixed guide rope;

[0106] The guide rope is fixed by the fixing component 29. When the fixing component 29 is connected to the mounting shell 24 together with the clamping component 28, the guide rope can be fixed and the guide rope can be quickly dropped later. At the same time, the fixing component 29 and the like are dropped together with the guide rope, so that the end of the dropped guide rope has a certain weight, which further increases the speed of dropping the guide rope and reduces the probability that the guide rope is entangled on the drone 1 due to the wind after being dropped.

[0107] The guide rope is located at the bottom of the landing gear of the UAV 1 after being fixed by the mounting member 21, the connecting assembly 26 and the mounting shell 24, thereby reducing the probability of the guide rope being entangled on the UAV 1 when the UAV 1 drives the guide rope to move, and facilitating the use of stable towing of the guide rope.

[0108] See also Fig.10 , the limiting assembly 291 includes:

[0109] The limiting sleeve 2913 is fixedly sleeved on the side wall of the clamping rod 282, and the outer wall diameter of the limiting sleeve 2913 is larger than the inner wall diameter of the mounting shell 24, so as to limit the distance that the limiting clamping block 281 enters into the mounting shell 24;

[0110] The insertion rods 2911 are fixed in a circular array on the top of the limiting sleeve 2913, and the bottom of the mounting shell 24 is provided with slots 2912 adapted to the insertion rods 2911, and the top of the insertion rods 2911 and the bottom inner wall of the slots 2912 are both designed in an arc shape.

[0111] In a specific implementation, after the limiting block 281 is engaged with the limiting claw 201, the insertion rod 2911 is inserted into the slot 2912 to connect the insertion rod 2911 with the mounting shell 24, thereby limiting the position of the clamping rod 282 and the limiting block 281 in the mounting shell 24, so that the limiting block 281 is relatively vertically arranged in the mounting shell 24, so as to avoid the limiting block 281 from deflecting under the traction of the guide rope, so as to avoid affecting the stability of the engagement between the limiting claw 201 and the limiting block 281, and to ensure that the position of the fixing component 29 is always correct, thereby improving the stability of the fixing component 29 in fixing the guide rope;

[0112] By providing the limiting sleeve 2913, it is convenient to install the insertion rod 2911 and limit the distance of the limiting block 281 entering the installation shell 24, thereby preventing the limiting block 281 from excessively entering the installation shell 24, which is convenient for practical use.

[0113] The electronic devices such as the first electromagnet 252 and the second electromagnet 253 of the present invention are connected to the power supply of the drone 1 or the power supply and controller externally connected to the drone 1 through wires to facilitate remote control and use. The above are all existing technologies and will not be elaborated here. The first electromagnet 252 and the second electromagnet 253 are usually only used when the guide rope is dropped, and have little effect on the endurance of the drone 1.

[0114] The embodiment of the present invention also provides a method for using an auxiliary device for high-altitude installation of power cables, using an auxiliary device for high-altitude installation of power cables, the method comprising the following steps:

[0115] S1: When it is necessary to install power cables at high altitude, the guide rope is fixed by the fixing assembly 29 to connect the guide rope to the installation mechanism 2. When the drone 1 is flying, the guide rope will be pulled to move, so that the guide rope is brought to the designated position, such as the power tower, by the drone 1. With the cooperation of the staff on the power tower, it can assist in the subsequent installation of cables at high altitude.

[0116] S2: During the movement of the guide rope, when encountering an accident due to strong airflow or the like, the limit shell 22 is driven downward by the driving component 25, so that the limit shell 22 drives the limit claw 201 of the clamping component 20 to rotate, so that the block component 28 is separated from the clamping component 20, so as to drop the guide rope. At the same time, during the downward movement of the limit shell 22, the connection component 26 cooperates with the extrusion component 27, so that the limit shell 22 drives the extrusion component 27 to move, so that the extrusion component 27 squeezes the second spring, thereby providing downward elastic potential energy to the limit block 281 of the block component 28, so that when the limit claw 201 of the clamping component 20 is separated from the limit block 281 of the block component 28, the block component 28 can move downward quickly, so as to quickly drop the guide rope, etc., reduce the influence of sudden situations such as strong airflow on the subsequent cable installation, and reduce the probability of damaging the drone 1, so as to facilitate the actual use of high-altitude cable installation;

[0117] By installing the shell 24, the connecting assembly 26 and the mounting member 21, the guide rope is located at the bottom of the landing gear of the drone 1 when the guide rope moves with the drone 1, thereby reducing the probability of the guide rope being entangled on the landing gear due to the influence of airflow, thereby reducing the probability of the guide rope being unable to be dropped later, and facilitating the actual installation of the cable.
