Description

Technical Field

[0001] This utility model relates to the field of tethered drone technology, specifically a tethered drone with cable management function. Background Technology

[0002] Tethered drones differ from traditional multi-rotor drones in that they are characterized by prolonged continuous flight and typically employ hovering maneuvers at a fixed altitude. The power source for maintaining this extended flight is continuous electrical energy transmitted via a fiber optic composite cable, and the quality of the cable's deployment and retrieval mechanism directly impacts the drone's flight safety and performance.

[0003] When a drone is connected to a cable, the cable needs to be manually pulled out. Since the walking speed of the personnel is not fixed, the cable pulling speed is inconsistent. If the cable is pulled too fast, and the reeling device is not released in time, the cable will be stretched, resulting in the cable being subjected to greater tension and easily causing damage to the cable. If the cable is released too fast, the cable will spread out on the surface of the reel, and the tension of the cable during reeling is not easy to control. Utility Model Content

[0004] The purpose of this invention is to provide a tethered drone with cable management capabilities to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tethered drone with cable management function includes a deployment and retrieval device, wherein a winding drum is rotatably connected inside the deployment and retrieval device, and a cable is wound around the outside of the winding drum. The drone also includes:

[0007] A cable assembly is fixedly installed on the lower surface inside the take-up and take-down device. The cable assembly includes two fixed seats fixedly installed on the lower surface inside the take-up and take-down device. A reciprocating screw is rotatably connected inside the two fixed seats. A movable support seat is movably provided above the reciprocating screw. A drive wheel is symmetrically rotatably connected inside the support seat. A driven wheel is rotatably connected inside the support seat above the drive wheel.

[0008] Two drive components are arranged and symmetrically fixedly installed on one side surface of the support base.

[0009] Furthermore, a No. 1 motor for driving the winding drum to rotate is fixedly installed on one side surface of the take-up and unwinding device, and a pulley assembly is fixedly connected to one end of the reciprocating screw and the winding drum that passes through the take-up and unwinding device.

[0010] Furthermore, a screw nut is screwed onto the outer surface of the reciprocating screw, and the upper end of the screw nut is fixedly connected to the support base.

[0011] Furthermore, the lower surface inside the retracting device is symmetrically and fixedly installed with a first slide rod on both sides of the reciprocating lead screw. Slide sleeves are slidably connected to the outer sides of the two first slide rods, and the upper ends of the two slide sleeves are fixedly connected to the support base.

[0012] Furthermore, the driving component includes:

[0013] The second sliding rod is fixedly installed on one side surface of the support base;

[0014] The fixed frame is slidably connected to the outer surface of the second slide rod;

[0015] Motor No. 2 is fixedly installed on the inner surface of the fixed frame.

[0016] Preferably, an electric push rod is fixedly installed on the lower surface of the support base, and the output end of the electric push rod is fixedly connected to the fixed frame.

[0017] Preferably, a locking block is fixedly installed at the output end of the second motor, and a locking seat is fixedly installed at one end of the drive wheel that passes through the support base, with the locking block and the locking seat being movably connected.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The No. 1 motor drives the take-up drum to rotate, and through the transmission of the pulley assembly, the reciprocating screw rotates. Under the sliding limit of the sliding sleeve and the No. 1 slide rod, the screw nut drives the support seat to move, adjusting the position of the cable during winding and unwinding, so that the cable is evenly wound or unwound from the surface of the take-up drum.

[0020] 2. During cable unwinding, the drive wheel closest to the take-up drum rotates under the drive of motor number two, maintaining tension on the cable between the take-up drum and the drive wheel. The drive wheel furthest from the take-up drum remains stationary, causing the cable to bend between the two drive wheels. Then, the locking block at the drive wheel furthest from the take-up drum separates from the locking seat, causing it to rotate with the cable, thereby adjusting the tension of the cable during unwinding. If the cable is pulled too fast, the bent cable between the two drive wheels is released, preventing the tension from stretching the cable on the surface of the take-up drum and improving the protection of the cable. At the same time, it prevents the cable from spreading out on the surface of the take-up drum when the cable is unwound too quickly, making it easy to control the tension of the cable during unwinding and winding.

[0021] 3. During winding, the locking block and locking seat near the drive wheel of the winding drum separate, while the drive wheel away from the winding drum rotates under the drive of motor No. 2, so that the cable has a certain tension when winding, and the cable is prevented from being loosely wrapped on the surface of the winding drum.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 In this embodiment of the present invention, a tethered drone with cable management function includes a take-up and take-down device 1. A take-up drum 101 is rotatably connected inside the take-up and take-down device 1. A cable 102 is wound around the outside of the take-up drum 101. A cable arrangement assembly 2 is fixedly installed on the lower surface inside the take-up and take-down device 1. The cable arrangement assembly 2 includes two fixed seats 201 fixedly installed on the lower surface inside the take-up and take-down device 1. A reciprocating screw 202 is rotatably connected inside the two fixed seats 201. A movable support seat 206 is movably provided above the reciprocating screw 202. A drive wheel 207 is symmetrically rotatably connected inside the support seat 206. A driven wheel 208 is rotatably connected inside the support seat 206 above the drive wheel 207. Two drive components 3 are arranged and symmetrically fixedly installed on one side surface of the support seat 206.

[0030] Specifically, the take-up drum 101 is used to take up and unwind the cable 102, which passes between the drive wheel 207 and the driven wheel 208. The cable laying assembly 2 moves the take-up and unwinding position of the cable 102, and the drive assembly 3 drives the two drive wheels 207 to rotate respectively, adjusting the tension of the cable 102.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, a No. 1 motor 104 for driving the take-up drum 101 to rotate is fixedly installed on one side surface of the take-up and unwinding device 1, and a pulley assembly 103 is fixedly connected to the reciprocating screw 202 and the end of the take-up drum 101 that passes through the take-up and unwinding device 1.

[0033] In this embodiment, motor 104 drives take-up drum 101 to rotate, and through the transmission of pulley assembly 103, reciprocating screw 202 rotates.

[0034] like Figure 2-4 As shown, in this embodiment, the drive assembly 3 includes: a second slide rod 301 fixedly installed on one side surface of the support base 206; a fixed frame 302 slidably connected to the outer surface of the second slide rod 301; and a second motor 303 fixedly installed on the inner surface of the fixed frame 302. An electric push rod 304 is fixedly installed on the lower surface of the support base 206, and the output end of the electric push rod 304 is fixedly connected to the fixed frame 302. A locking block 305 is fixedly installed on the output end of the second motor 303, and a locking seat 306 is fixedly installed at one end of the drive wheel 207 that passes through the support base 206. The locking block 305 and the locking seat 306 are movably inserted into each other.

[0035] In practice, the electric push rod 304 extends and retracts, controlling the movement of the second motor 303, causing the locking block 305 to engage and disengage from the locking seat 306. The sliding of the fixed frame 302 and the second sliding rod 301 increases the stability of the second motor 303 during movement. During unwinding, the drive wheel 207 near the take-up drum 101 rotates under the drive of the second motor 303, maintaining tension on the cable 102 between the take-up drum 101 and the drive wheel 207. The drive wheel 207 away from the take-up drum 101 remains stationary under the constraint of the second motor 303, causing the cable 102 to bend between the two drive wheels 207. Then, the locking block 305 away from the drive wheel 207 of the take-up drum 101 separates from the locking seat 306, allowing it to move with the cable 102 as it is pulled. The movement of 02 causes the cable 102 to rotate, thereby adjusting the tension when the cable 102 is released. When the speed at which the person pulls the cable 102 is too fast, the cable 102 bent between the two drive wheels 207 is released, avoiding the tension from stretching the cable 102 on the surface of the take-up drum 101, thus improving the protection effect of the cable 102. At the same time, it prevents the cable 102 from spreading out on the surface of the take-up drum 101 when the release speed is too fast, making it easier to control the tension of the cable 102 during release and take-up. When the cable is taken up, the locking block 305 and the locking seat 306 near the drive wheel 207 of the take-up drum 101 separate, and the drive wheel 207 away from the take-up drum 101 rotates under the drive of the second motor 303, so that the cable 102 has a certain tension when it is wound up, preventing the cable 102 from loosely winding on the surface of the take-up drum 101.

[0036] Example 2

[0037] Based on Embodiment 1, in order to address the problem that the cable 102 is not easy to be evenly wound onto the surface of the take-up drum 101.

[0038] like Figure 3 and Figure 5 As shown, in this embodiment, a screw nut 204 is screwed onto the outer surface of the reciprocating screw 202, and the upper end of the screw nut 204 is fixedly connected to the support base 206; a sliding rod 203 is symmetrically fixedly installed on the lower inner surface of the take-up and take-down device 1 on both sides of the reciprocating screw 202, and a sliding sleeve 205 is slidably connected to the outer side of each of the two sliding rods 203, and the upper ends of the two sliding sleeves 205 are fixedly connected to the support base 206.

[0039] In practice, the reciprocating screw 202 rotates, and under the sliding limit of the sliding sleeve 205 and the first sliding rod 203, the screw nut 204 drives the support seat 206 to move, adjusting the position of the cable 102 when winding and unwinding, so that the cable 102 is evenly wound or unwound from the surface of the winding drum 101.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
