Description
Technical Field
[0001] This invention relates to the field of tethered unmanned aerial vehicles (UAVs), and more particularly to a tether line drying device. Background Technology
[0002] Currently, when tethered drones operate in the rain, they need to use tether cables inside the ground tether box to connect to the drone in the air for continuous power supply. Both the drone and the tether box are easy to waterproof. However, rainwater can easily flow into the tether box through the cable outlet. The tether box contains many electrical devices that are connected to the power grid and operate at high voltage. Once water gets in, it will cause personal injury and damage to the electrical equipment. Summary of the Invention
[0003] To overcome the problem that rainwater may enter the tethering box along the tether line during the operation of pre-filled tethered drones, the present invention provides a tether line drying device. The technical solution adopted by the present invention to solve its technical problem is as follows:
[0004] A tethered wire drying device includes a fan assembly and a drying chamber connected to the air outlet of the fan assembly. The drying chamber, from top to bottom, has a first wire inlet, a first air duct, a first wire hole, a second air duct, and a second wire hole. Several air outlets are arranged around the first wire inlet. The first air duct communicates with the second air duct, and a rotatable impeller is provided at the connection point. A baffle is provided on one side of the impeller, and a water outlet is connected to the lower end of the baffle. The second air duct is connected to the air outlet of the fan assembly. The tethered wire passes through the first wire inlet into the first air duct, then through the first wire hole into the second air duct, and finally through the second wire hole out of the second air duct. The fan assembly blows drying air into the second air duct, which blows the moisture on the tethered wire onto the impeller and drives the impeller to rotate. The impeller, through centrifugal force, throws the moisture onto the baffle, and the moisture flows along the baffle to the water outlet. Simultaneously, the rotation of the impeller guides the drying air to the first air duct and drives it to be blown out through the air outlet.
[0005] Furthermore, all air outlets are oriented towards the axis of the first wire passage to prevent rainwater from flowing into the first wire passage along the mooring line.
[0006] Furthermore, the drying oven is also equipped with a first roller assembly, a second roller assembly, and a second wire passage. The first roller assembly and the second roller assembly are arranged opposite to each other. The tethered wire that passes through the second wire passage passes between the first roller assembly and the second roller assembly. The first roller assembly and the second roller assembly can squeeze the tethered wire and absorb the moisture on it. Then the tethered wire passes out through the second wire passage.
[0007] Furthermore, the first roller assembly includes a first drying roller, a first sliding member, a first sliding groove, an abutment member, and a first nut; the first sliding groove is fixed to the inner wall of the drying chamber, the first sliding member is slidably disposed in the first sliding groove, the first drying roller is rotatably disposed on the first sliding member, the first nut is threadedly connected to the drying chamber, the abutment member abuts between the first nut and the first sliding member, and the distance between the first drying roller and the second roller assembly can be adjusted by the first nut.
[0008] Furthermore, the second roller assembly includes a second drying roller, a second sliding member, a second sliding groove, an elastic member, and a second nut; the second sliding groove is fixed to the inner wall of the drying chamber, the second sliding member is slidably disposed in the second sliding groove, the second drying roller is rotatably disposed on the second sliding member, the second nut is threadedly connected to the drying chamber, and the elastic member is disposed between the second nut and the second sliding member. The pressure between the second drying roller and the first drying roller can be adjusted by means of the second nut.
[0009] Furthermore, both the first and second drying wheels are made of EVA foam.
[0010] Furthermore, the second air duct is connected to the air outlet of the fan assembly via a connecting sleeve. The width of the air outlet of the fan assembly is greater than the width of the second air duct, and the connecting sleeve is funnel-shaped to increase the air pressure of the second air duct.
[0011] Furthermore, both the first and second wire passages are formed by surrounding with Teflon material, and rubber rings are provided on both the first and second wire passages.
[0012] A tethering box is provided, which includes a winch and a water outlet pipe. A drying device is fixed to the inner wall of the tethering box. A first cable passage and an air outlet protrude from the upper surface of the tethering box. One end of the water outlet pipe is connected to a water outlet, and the other end extends out from the side wall of the tethering box. The tethering line of the tethered drone extends down from the tethered drone, passes through the drying device, and connects to the winch.
[0013] The beneficial effects of this invention are:
[0014] The tethered wire drying device includes a fan assembly and a drying chamber connected to the air outlet of the fan assembly. The drying chamber, from top to bottom, has a first wire inlet, a first air duct, a first wire hole, a second air duct, and a second wire hole. Several air outlets are arranged around the first wire inlet. The first air duct is connected to the second air duct, and a rotatable impeller is installed at the connection point. A baffle is installed on one side of the impeller, and a water outlet is connected to the lower end of the baffle. The second air duct is connected to the air outlet of the fan assembly. The tethered wire passes through the first wire inlet into the first air duct, then through the first wire hole into the second air duct, and finally out of the second air duct through the second wire hole. The fan assembly blows drying air into the second air duct, which blows the moisture on the tethered wire onto the impeller and drives the impeller to rotate. The impeller, through centrifugal force, throws the moisture onto the baffle, and the moisture flows along the baffle to the water outlet. Simultaneously, the rotation of the impeller guides the drying air to the first air duct and drives it out through the air outlet, effectively drying the tethered wire. Attached Figure Description

[0027] To better understand the purpose, structure, and function of the present invention, the embodiments of the present invention, "a tethered wire drying device and a tethered box", will be described in further detail below with reference to the accompanying drawings.
[0028] See Figures 1-3 In this embodiment, the tethered wire drying device includes a fan assembly 200 and a drying chamber 100. The drying chamber 100 is detachably and fixedly connected to the air outlet of the fan assembly 200. The drying chamber 100 is provided from top to bottom with a first wire passage 101, a first air duct 102, a first wire passage hole 103, a second air duct 104, and a second wire passage hole 105. A plurality of air outlet holes 107 are provided around the first wire passage 101. The first air duct 102 communicates with the second air duct 104, and a rotatable impeller 108 is provided at the communication point. A baffle 109 is provided on one side of the impeller 108, and a water outlet 110 is connected to the lower end of the baffle 109. The second air duct 104 is connected to the fan assembly 200. Air outlet; the tethered wire passes through the first wire passage 101 into the first air duct 102, and through the first wire passage hole 103 into the second air duct 104, and then through the second wire passage hole 105 out of the second air duct 104; when the drying device is running, the fan assembly 200 blows drying air into the second air duct 104, the drying air blows the moisture on the tethered wire onto the impeller 108 and drives the impeller 108 to rotate, the impeller 108 throws the moisture onto the baffle wall 109 through centrifugal force, and the moisture flows along the baffle wall 109 to the outlet 110; at the same time, the rotation of the impeller 108 guides the drying air to the first air duct 102 and drives the drying air to be blown out from the air outlet 107, completing the drying operation of the tethered wire.
[0029] See further Figure 2 and Figure 3 In some embodiments, the air outlets 107 are all oriented toward the axis of the first wire passage 101. With this design, the dry air blown out by the air outlets 107 will be concentrated on the tethering wire that passes through the first wire passage 101, which can blow away the rainwater flowing down the tethering wire and limit the rainwater from flowing into the first wire passage 101 along the tethering wire, thus keeping the drying device dry.
[0030] See further Figure 2In some embodiments, the drying chamber 100 is further provided with a first roller assembly 111, a second roller assembly 112, and a second thread passage 106. The first roller assembly 111 and the second roller assembly 112 are arranged opposite to each other. The tethered thread that passes through the second thread passage 105 passes between the first roller assembly 111 and the second roller assembly 112. The first roller assembly 111 and the second roller assembly 112 can squeeze the tethered thread and absorb the moisture on it. Then the tethered thread passes through the second thread passage 106 to further absorb the moisture on the tethered thread and further ensure the dryness of the tethered thread.
[0031] More specifically, the first roller assembly 111 includes a first drying roller 1111, a first sliding member 1112, a first sliding groove 1113, an abutment member 1114, and a first nut 1115; the first sliding groove 1113 is fixed to the inner wall of the drying chamber 100, the first sliding member 1112 is slidably disposed in the first sliding groove 1113, the first drying roller 1111 is rotatably disposed on the first sliding member 1112, the first nut 1115 is threadedly connected to the drying chamber 100, and the abutment member 1114 abuts against the first nut 1115 and the first sliding member 1112. The distance between the first drying roller 1111 and the second roller assembly 112 can be adjusted by the first nut 1115. The second roller assembly 112 includes a second drying roller 1121, a second sliding member 1122, a second sliding groove 1123, an elastic member 1124, and a second nut 1125. The second sliding groove 1123 is fixed to the inner wall of the drying chamber 100. The second sliding member 1122 is slidably disposed in the second sliding groove 1123. The second drying roller 1121 is rotatably disposed on the second sliding member 1122. The second nut 1125 is threadedly connected to the drying chamber 100. The elastic member 1124 is disposed between the second nut 1125 and the second sliding member 1122. The pressure between the second drying roller 1121 and the first drying roller 1111 can be adjusted by the second nut 1125. By adjusting the first nut 1115 and the second nut 1125, the distance between the first drying wheel 1111 and the second drying wheel 1121, as well as their centering position, can be adjusted. The compression of the first drying wheel 1111 and the second drying wheel 1121 can maintain the tension of the tethering line and prevent it from loosening. The first drying wheel 1111 and the second drying wheel 1121 are preferably made of EVA foam cotton, which can effectively compress the tethering line and absorb moisture. Of course, other absorbent materials with good effects can also be used, and adaptive changes can be made according to specific circumstances. Both the first drying wheel 1111 and the second drying wheel 1121 are detachable for easy replacement.
[0032] See further Figure 1In some embodiments, the second air duct 104 is connected to the air outlet of the fan assembly 200 via a connecting sleeve 300. The width of the air outlet of the fan assembly 200 is greater than the width of the second air duct 104. The connecting sleeve 300 is funnel-shaped. This design provides a narrowing effect at the connection point. When the drying air is blown into the second air duct 104 by the fan assembly 200, the air pressure entering the second air duct 104 can be increased.
[0033] See further Figure 3 In some embodiments, the first wire passage 101 and the second wire passage 106 are both formed by surrounding with Teflon material. Teflon material has good lubricity, which can ensure the passage of the tethered wire while reducing the friction of the tethered wire. A rubber ring 113, preferably silicone rubber, is fixedly connected to the first wire passage 103 and the second wire passage 105. The rubber ring 113 can ensure the smooth passage of the tethered wire, while preventing high-speed airflow from passing through the first wire passage 103 and the second wire passage 105, and can also block some moisture from passing through the first wire passage 103 and the second wire passage 105.
[0034] See Figure 4 In some embodiments, a tether box 400 is designed, which uses the aforementioned tether line drying device. The tether box 400 is equipped with a winch 500 and a water outlet pipe 600. The drying device is fixed to the inner wall of the tether box 400. The first cable passage 101 and the air outlet 107 are exposed from the upper surface of the tether box 400. One end of the water outlet pipe 600 is connected to the water outlet 110, and the other end passes through the side wall of the tether box 400. The tether line of the tethered drone extends down from the tethered drone, passes through the drying device, and is connected to the winch 500. The tether line can be retracted and extended at the same time, and the tether line can be dried at the same time to ensure the dryness of the inside of the tether box 400 and ensure the safety of other electrical components inside.
[0035] In summary, the tethered wire drying apparatus of the present invention has the following advantages:
[0036] 1. The impeller 108 can separate the moisture blown out by the drying air, allowing the moisture to flow out from the outlet, and can also guide the drying air from the second air duct 104 into the first air duct 102, so that the drying air is blown out from the air outlet 107, achieving dry and wet separation and a good drying effect.
[0037] 2. All air outlets 107 face the axis of the first wire passage 101. The dry air blown out by the air outlets 107 will be concentrated on the tethering wire that passes through the first wire passage 101, which can blow away the rainwater flowing down the tethering wire and initially prevent rainwater from entering.
[0038] 3. A roller assembly 111 and a second roller assembly 112 are provided to squeeze the tie line and absorb the moisture on it, thereby further drying the tie line and serving as a second line of defense against drying.
[0039] 4. The fan assembly 200 blowing into the second air duct 104 has been narrowed, which can increase the air pressure entering the second air duct 104.
[0040] 5. The entire device has a simple structure and can be set up in the required application scenarios as needed. It is not limited to drying tethered wires, but can also be used for drying various other objects with different shapes and lines.
[0041] 6. Due to its simple structure, the drying device can be designed to be very small as needed, making it easy to move. It can be mounted on many components or other components can be added to it, such as casters and handles, to create a convenient push-type drying device. This device still has a lot of untapped potential.
