Description

Technical Field

[0001] The invention relates to the technical field of tower-based unmanned aerial vehicle machine nests, in particular to a tower-based unmanned aerial vehicle machine nest without power drive. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device, or is operated completely or intermittently autonomously by an onboard computer. In the civilian field, quadcopters are the main type of drones, which are used in many fields such as aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, and disaster relief. However, drones are restricted by their own weight and the capacity of the power batteries they can carry is limited, resulting in a short endurance time for a single flight of the drone. During the power inspection process, it is often necessary to install drone nests at intervals along the transmission lines, and charge the drones during the inspection through the drone nests, so as to extend the drone's flight distance and improve inspection efficiency.

[0003] The drone nests in the prior art are generally installed in the open space around the power pylons. However, since some power transmission lines need to cross mountains and forests, when the drone nests are installed in the mountains and forests, tall trees will block the drone from landing, increasing the risk of the drone crashing. At the same time, animals in the mountains and forests will also pose a threat to the drone nests, resulting in a high failure rate of the drone nests. Therefore, to solve this problem, it is often necessary to install the drone nests on the power pylons. The tower-based drone nests in the prior art all need to be operated by live equipment such as motors to open and close the box doors. These live equipment are extremely susceptible to electromagnetic interference on the high-voltage power pylons, resulting in their very low service life, safety, stability and reliability, which increases the failure rate of the drone nests and increases the operating and maintenance costs.

[0004] The Chinese invention patent CN202010831806.0: A tower-based UAV take-off and landing system, including a parking box with an opening facing upward and fixed on a pole tower, and a positive and negative split conductive bracket fixed at the bottom of the UAV; the top of the parking box is symmetrically and slidably connected with a box slide cover, and the interior of the parking box is rotatably embedded with a charging seat with an opening facing upward and provided with rotational power by the positive and negative split conductive brackets, a transmission unit is provided on the inner wall of the parking box, and a power supply unit is provided at the bottom of the parking box, which penetrates the charging seat upward and provides charging power for the positive and negative split conductive brackets; the power input ends of the transmission unit are both connected to the power of the charging seat, and the power output ends of the transmission unit are both connected to the power of the box slide cover. When the drone is not being charged, the sliding cover of the box always remains open, which makes it easy for foreign objects to enter and has a very high failure rate. In addition, the power source for opening and closing the sliding cover of the box comes from the drone. The drone needs to rotate during landing, which increases the landing risk of the drone. At the same time, the rotation force given by the drone is limited, resulting in a low success rate for opening and closing the sliding cover of the box, poor reliability and stability, and the drone is prone to collision with the sliding cover of the box, resulting in poor safety. The transmission unit has a complex structure and high cost, so it is necessary to improve it. Summary of the invention

[0037] The following are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.

[0038] A non-powered tower-based drone nest, such as Figures 1 to 4 As shown, it includes a box body 1 and two symmetrically arranged box doors 2 slidably installed on the upper part of the box body 1. A lifting port 11 is opened on the upper part of the box body 1. A charging chamber 12 is arranged inside the box body 1. A lifting seat 3 is slidably installed on the charging chamber 12 up and down. A transmission mechanism is arranged between the two box doors 2 and the lifting seat 3 respectively. One end of the transmission mechanism is connected to the lifting seat 3 and the other end is connected to the box door 2. The two box doors 2 move relatively close to or away from each other. A tension adjustment mechanism is respectively installed on the rear side of the two box doors 2. The two tension adjustment mechanisms are respectively connected to the lifting seat 3. The corresponding box doors 2 are connected, and the two tension adjustment mechanisms are provided with a tension F for driving the box doors 2 to move relatively away, the tension F is less than or equal to the weight of the drone and is greater than the weight of the lifting seat 3; the lifting seat 3 is provided with a charging mechanism and an upper wiring mechanism, and the upper part of the lifting seat 3 has a lowering platform 31, the charging mechanism is electrically connected to the upper wiring mechanism, and the lower part of the charging chamber 12 is provided with a lower wiring mechanism and a power supply circuit, the lower wiring mechanism is electrically connected to the power supply circuit, and the upper wiring mechanism conflicts with the lower wiring mechanism and is electrically connected during charging.

[0039] The traditional tower-based drone nest needs to use a motor or the drone itself to provide power to open and close the box door 2, which is easily affected by electromagnetic interference, has poor reliability and stability, a complex transmission mechanism, high cost, high failure rate, and poor safety. The present invention, on the other hand, uses the drone's own weight to press down the lifting seat 3, and as the lifting seat 3 descends, drives the two box doors 2 to slide relative to each other to close the lifting port 11. No live equipment such as a motor is required as a power source, which reduces electromagnetic interference, improves reliability and stability, and also does not require the drone to rotate and drive, thereby improving safety. When the drone takes off and leaves the lifting seat 3, the lifting seat 3 loses the downward pressure of the drone, and automatically resets and opens the two box doors 2 through the tension adjustment mechanism. No motor is required to provide power for opening and closing the box doors 2. The tension adjustment mechanism can adjust the tension F according to the weight of the drone, thereby expanding the scope of use. After rising, the lifting seat 3 simultaneously blocks the lifting port 11, and ensures that the charging chamber 12 is closed in the initial state, thereby ensuring the cleanliness of the charging chamber 12 and extending the service life. When the pulling force F is less than the weight of the drone, the drone only needs to slowly and gently land on the take-off and landing platform 31. When the pulling force F is equal to the weight of the drone, the drone needs to generate a downward impact force on the lifting seat 3 when landing, so that the lifting seat 3 descends with the drone. When the pulling force F is less than the weight of the drone, the drone can be protected and the impact on the drone can be reduced. When the pulling force F is equal to the weight of the drone, the lifting seat 3 can be prevented from accidentally falling and the stability can be improved.

[0040] Specifically, the transmission mechanism includes a rope 41, a first end of the rope 41 is fixedly connected to the lifting seat 3, and a second end of the rope 41 is fixedly connected to the corresponding box door 2; two slide rails 13 are arranged at intervals on the upper part of the box body 1, and the two slide rails 13 are respectively located at the front and rear sides of the lifting port 11, and at least two sliders 24 are arranged at intervals on the lower part of the box door 2, and the two sliders 24 are respectively slidably connected to the corresponding slide rails 13. The rope 41 is made of steel wire rope, and the box door 2 and the lifting seat 3 are connected by steel wire rope transmission, which has a simple structure, low cost, high reliability and stability, and reduced maintenance cost. The box door 2 and the box body 1 are connected by the slide rail 13 and the slider 24, and the slider 24 moves on the slide rail 13 to reduce friction, so that the box door 2 moves more smoothly, avoids jamming and failure of the box door to open and close, and further improves stability and reliability.

[0041] Specifically, two ropes 41 are respectively arranged between the two doors 2 and the lifting seat 3, the first end of each rope 41 is respectively fixedly connected to the four corners of the lifting seat 3, the second end of each rope 41 is respectively fixedly connected to the front and rear sides of the corresponding door 2, and each rope 41 is provided with a pulley mechanism 14, and each pulley mechanism 14 is fixedly installed on the upper part of the box body 1. The rope 41 is guided by the pulley mechanism 14 to prevent the rope 41 from directly rubbing on the edge of the box body 1, further reducing the friction, extending the service life of the rope 41, and preventing the rope 41 from being worn off.

[0042] Specifically, a rear baffle 21 extends downward from the side edge of the two doors 2 that are away from each other, and a side baffle 22 extends downward from the front and rear side edges of the two doors 2 respectively, and a side sealing strip 23 is provided on the opposite sides of any door 2 or the two doors 2; a positive sealing strip 32 is provided on the edge of the lifting platform 31 and / or the upper wall of the charging chamber 12, and the positive sealing strip 32 is located at the periphery of the lifting port 11. After the doors 2 are closed, the side baffle 22 and the rear baffle 21 wrap the box body 1, and the side sealing strip 23 seals the gap between the two doors 2, thereby improving the airtightness of the charging chamber 12 when the doors 2 are closed; the positive sealing strip 32 seals the gap between the lifting seat 3 and the box body 1 when the doors 2 are opened, thereby improving the airtightness of the charging chamber 12 when the doors 2 are opened, and improving the waterproofness.

[0043] Specifically, two side hooks are respectively arranged on the inner side surfaces of the two rear baffles 21 of the two doors 2, and the four corners of the lifting platform 31 are respectively fixedly installed with positive hooks 43, and the first and second ends of the rope 41 are respectively fixedly installed with fasteners 42, and the fasteners 42 at the first end of the rope 41 are connected to the corresponding positive hooks 43, and the fasteners 42 at the second end of the rope 41 are connected to the corresponding side hooks. The four ropes 41 are respectively connected to the four corners of the lifting platform 31, so that the force of the lifting seat 3 is more uniform and the lifting process is more stable. Fasteners 42 are arranged at both ends of the rope 41, and they are directly fastened to the positive hooks 43 and the side hooks through the fasteners 42, which is convenient for disassembly and assembly, and is convenient for maintenance and assembly.

[0044] Specifically, a raised charging pile 33 is provided on the take-off and landing platform 31, and the vertical height of the charging pile 33 is the same as the distance between the bottom of the drone and the bottom of the landing gear; the charging mechanism includes a wireless charging coil 34 and a charging circuit, the wireless charging coil 34 is provided on the top of the charging pile 33, the charging circuit is fixedly installed inside the lifting seat 3, the wireless charging coil 34 is electrically connected to the charging circuit, and the charging circuit is electrically connected to the upper wiring mechanism. When the drone lands, the landing gear contacts the take-off and landing platform 31, and the lower part of the drone is provided with a corresponding wireless charging receiving mechanism. The wireless charging mechanism contacts the wireless charging coil 34 to wirelessly charge the drone, without wiring, without exposed metal terminals, and without oxidation. The reliability and safety are high, and the charging pile 33 also plays a role in positioning.

[0045] Specifically, the lifting seat 3 is provided with at least one upper drainage hole 36 located at the periphery of the charging pile 33, and the upper drainage hole 36 penetrates the lifting seat 3. At least one lower drainage hole is provided at the bottom of the box body 1, and a drainage hose 15 is connected between the upper drainage hole 36 and the lower drainage hole; a shock-absorbing protection device is provided at the bottom of the charging chamber 12, and the shock-absorbing protection device includes a lower fixed plate 51, an upper fixed plate 52 and at least one shock-absorbing spring 53, the lower fixed plate 51 is fixedly installed on the lower wall of the charging chamber 12, and the shock-absorbing spring 53 is fixedly installed between the lower fixed plate 51 and the upper fixed plate 52, and the upper fixed plate 52 is matched with the lifting seat 3. When the box door 2 is opened and the lifting seat 3 seals the lifting port 11, in rainy weather, rainwater is discharged from the upper drainage hole 36 through the drainage hose 15 and from the lower drainage hole, preventing rainwater from accumulating on the lifting and lowering platform 31, causing the lifting seat 3 to fall unexpectedly, thereby improving reliability and stability. The shock absorbing protection device provides a buffering force when the lifting seat 3 descends to the bottom, reducing the impact of the lifting seat 3 on the lower wiring mechanism when descending, and further improving reliability and stability.

[0046] Specifically, the upper wiring mechanism includes a positive wiring socket 71 and a negative wiring socket 72, and the lower wiring mechanism includes a positive wiring plug 61 and a negative wiring plug 62. The positive wiring plug 61 and the negative wiring plug 62 both include a lower socket 63 and a lower wiring terminal 64. The two lower wiring terminals 64 are electrically connected to the power supply circuit respectively. The two lower sockets 63 are spaced apart at the bottom of the charging chamber 12. The lower wiring terminal 64 is arranged at the upper part of the lower socket 63 and protrudes upward from the upper end surface of the lower socket 63. The positive wiring socket 71 and the negative wiring socket 72 are spaced apart at the lower part of the lifting seat 3. 71 is located just above the positive wiring plug 61, and the negative wiring socket 72 is located just above the negative wiring plug 62. A charging socket 73 with an opening facing downward is provided in the center of the positive wiring socket 71 and the negative wiring socket 72. A conductive sheet is provided on the inner wall of the charging socket 73. The two conductive sheets are electrically connected to the charging circuit respectively. When charging, the lower wiring terminal 64 of the positive wiring plug 61 is inserted into the charging socket 73 of the positive wiring socket 71, and the lower wiring terminal 64 of the negative wiring plug 62 is inserted into the charging socket 73 of the negative wiring socket 72. The two lower wiring terminals 64 are respectively in contact with the corresponding two conductive sheets. When the lifting seat 3 rises to seal the lifting port 11, the lifting seat 3 is not connected to any power source, so the wireless charging coil 34 is not powered, reducing standby energy consumption. When the lifting seat 3 descends under the weight of the drone, the lower wiring terminal 64 is inserted into the charging socket 73 and contacts the conductive sheet, thereby supplying power to the charging circuit through the power supply circuit and automatically starting wireless charging; the charging socket 73 faces downward to prevent rainwater and debris from entering the charging socket 73, which is more reliable and safer. Of course, the lower wiring mechanism and the upper wiring mechanism are not limited to the way the lower wiring terminal 64 contacts the conductive sheet, but can also be in contact with the conductive sheet through elastic wiring pins.

[0047] Specifically, the charging pile 33 is provided with a magnetic attraction mechanism 35 for adsorbing and fixing the drone. The magnetic attraction mechanism 35 uses an electromagnet ring or a permanent magnet ring. The electromagnet ring or the permanent magnet ring is sleeved on the periphery of the wireless charging coil 34, and the electromagnet ring is electrically connected to the two lower terminals 64. When the drone lands, the magnetic attraction mechanism 35 attracts the drone, making the drone land more accurately, and can also fix the drone to prevent the drone from moving during charging, thereby improving the charging success rate.

[0048] Specifically, the left and right sides of the box body 1 are respectively provided with an adjustment bracket 16, the tension adjustment mechanism includes a tension spring 81 and an adjustment member, the adjustment member includes an adjustment threaded rod 82 and two adjustment nuts 83, one end of the adjustment threaded rod 82 is bent to form a hook portion 821, the two adjustment nuts 83 are threadedly connected with the adjustment threaded rod 82, the adjustment bracket 16 is provided with a rod-through hole, the adjustment threaded rod 82 is passed through the rod-through hole, the two adjustment nuts 83 are clamped and fixed to the adjustment bracket 16, the first end of the tension spring 81 is connected to the outer side of the box door 2, and the second end of the tension spring 81 is connected to the hook portion 821 of the adjustment threaded rod 82. The tension spring 81 gives the box door 2 a tension F to reset the box door 2, and the two adjustment nuts 83 are used to adjust the distance between the hook portion 821 of the adjustment threaded rod 82 and the adjustment bracket 16, thereby lengthening or retracting the tension spring 81 to achieve the adjustment of the tension F, so that it can adapt to drones of different weights and expand the scope of application.

[0049] The working principle of the present invention is as follows:

[0050] In the initial state, if Figure 1 and Figure 2 As shown, the two doors 2 move away from each other under the tension F of the tension spring 81 to open the two doors 2, and the doors 2 pull the rope 41 to make the lifting seat 3 rise simultaneously with the opening of the two doors 2 until the lifting seat 3 closes the lifting port 11.

[0051] When the drone is docked to charge, Figure 3 and Figure 4 As shown, the UAV lands on the take-off and landing platform 31, the wireless charging receiving mechanism of the UAV is aligned with the wireless charging coil 34, and the magnetic attraction mechanism 35 adsorbs and fixes the UAV. Under the weight of the UAV, the lifting seat 3 descends, and the rope 41 is pulled to overcome the tension F to move the two doors 2 toward each other until the two doors 2 are closed, and the lower terminal 64 is inserted into the charging socket 73 to contact the conductive sheet, and the power supply circuit supplies power to the charging circuit, and the wireless charging is automatically started.

[0052] After charging is completed, the drone takes off. As the drone leaves the lifting seat 3 , it returns to its initial state under the action of the tension F of the tension spring 81 , and flies out of the charging chamber 12 .

[0053] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
