Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a hydrogen-powered transport UAV. Background Art

[0002] Unmanned aerial vehicles (UAVs) are a rapidly developing new concept of aircraft, characterized by their maneuverability, rapid response, unmanned flight, and minimal operational requirements. Equipped with a variety of sensors, UAVs can transmit real-time images and detect high-risk areas, effectively complementing satellite remote sensing and traditional aerial remote sensing. Currently, the use of UAVs has expanded to military, scientific research, and civilian applications, with particular application in communications, meteorology, agriculture, oceanography, exploration, photography, rescue, disaster prevention and mitigation, crop yield estimation, drug control, and border patrol.

[0003] Transport drones are typically required to have high endurance, low power consumption, and a strong load-bearing capacity. However, in actual use, current drones generally use lithium batteries as their power source. As we all know, the energy density of lithium batteries is lower than that of hydrogen energy, and the volume and weight of lithium batteries with the same energy density are much larger than hydrogen energy. If lithium batteries are used as the power source of drones, they are limited by their weight and volume, which will increase the parasitic power consumption of the drone, thereby affecting the drone's endurance and carrying capacity. In addition, drones using lithium batteries are limited by charging speed, which will waste some charging time and affect the drone's overall transportation capacity. Therefore, the utility model proposes a hydrogen-powered transport drone. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a hydrogen-powered transport drone with long endurance and strong carrying capacity.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A hydrogen-powered transport drone comprises a main body in the form of a rectangular parallelepiped, with U-shaped support frames vertically arranged on both sides of the main body in the width direction, the two ends of the support frame opening being respectively mounted on the two sides of the main body in the length direction, the bottom length of the support frame being longer than the length between the two ends of the support frame opening; a power module being arranged between the two support frames.

[0007] Among them, the power module includes a base plate arranged horizontally between the two support frames, and side plates are vertically arranged on both sides of the width direction of the base plate and connected between the main body and the base plate; a accommodating space for the hydrogen fuel cell is formed between the base plate, the side plates and the main body, and the bottoms on both sides in the width direction of the base plate have U-shaped frames bent outward, and multiple U-shaped frames are arranged along the length direction of the base plate, and connecting rods are connected between two adjacent U-shaped frames, and multiple U-shaped frames are evenly distributed along the circumference of the U-shaped frames; a hydrogen storage bottle is placed on the U-shaped frame, and the hydrogen storage bottle is fixed by a Velcro arranged on the connecting rod; the hydrogen storage bottle is connected to the hydrogen fuel cell through a hydrogen transmission pipeline.

[0008] With the above structure, four high-power hydrogen fuel cells are placed in parallel in the accommodation space to provide power. The hydrogen storage bottles on the U-shaped frames on both sides of the drone provide hydrogen for the hydrogen fuel cells to generate electricity. Since the hydrogen fuel cell itself occupies a small space and the weight of hydrogen is small; under the same power density, the volume occupied by the hydrogen fuel cell plus the hydrogen storage bottle and its own weight are much smaller than those of the lithium battery. Therefore, the use of hydrogen fuel cells can reduce its own parasitic power consumption while ensuring power density, thereby improving endurance. The reduced mass can increase the weight of the carried items to improve the carrying capacity of the drone. Moreover, the amount of electricity stored in the high-power density lithium battery is also huge, which is limited by The current charging speed means that when the battery is exhausted, it takes a while to recharge before it can be used again, which reduces the carrying efficiency. In addition, the application scenarios of carrying drones are usually outdoors. When the drone's lithium battery is exhausted, there is generally no place to charge it, and the drone's working time will be further shortened. Hydrogen power can carry multiple hydrogen storage bottles. When the hydrogen used for power generation in the hydrogen storage bottle is used up, the Velcro can be opened to remove the hydrogen storage bottle and replace it with a hydrogen storage bottle filled with hydrogen to continue powering the battery. This not only solves the problem of long charging time, but also can be used to fix hydrogen storage bottles of different sizes by wrapping the Velcro around different connecting rods of the U-shaped frame, making it easy to replace and improve work efficiency.

[0009] Furthermore, four hydrogen fuel cells are arranged in the accommodating space, wherein two of the hydrogen fuel cells are placed horizontally on both sides of the length direction of the base plate, and two hydrogen fuel cells are vertically arranged between the two horizontally placed fuel cells; there are through-holes set through both sides of the length direction of the base plate, and there are through-holes set through the positions corresponding to the two vertically placed hydrogen fuel cells on the side plate; the fans of the hydrogen fuel cells are placed correspondingly in the through-holes.

[0010] This makes it easier for the hydrogen fuel cell to obtain enough oxygen from the outside to react with hydrogen to generate electricity, and it is also beneficial to use external cold air to cool the fuel cell.

[0011] Furthermore, organic arm clamps are fixedly provided on both sides of the width direction of the main body, and organic arms are provided at both ends of the length direction of the main body, and are symmetrically arranged with the other side of the width direction of the main body; the arms can be rotated in the horizontal direction, and when stored, they can be rotated inward to be in a straight line with the main body and stuck in the arm clamps; the arms in the length direction of the main body are not at the same horizontal height.

[0012] This helps to fix the machine arm during storage, making it easier to store and transport.

[0013] Furthermore, when the arm is fully extended, the angle between the arm and the main body is 120 degrees.

[0014] Furthermore, the bottom of the base plate may include more than just the pod that can be detached.

[0015] Furthermore, the two support frames are connected with reinforcing ribs, and an obstacle avoidance radar is provided on one of the reinforcing ribs.

[0016] Furthermore, the bottom of the support frame is wrapped with a layer of rubber pad.

[0017] In summary, the utility model has the advantages of easy replacement of hydrogen bottles and long battery life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described in detail below with reference to the embodiments.

[0022] A hydrogen-powered transport drone, such as Figures 1 to 4 As shown, it includes a main body 1 that is a rectangular parallelepiped as a whole, and a U-shaped support frame 2 is vertically arranged on both sides of the width direction of the main body 1.

[0025] When in use, place the hydrogen storage bottle on the U-shaped frame, wrap the hydrogen storage bottle with Velcro to fix it, and connect the hydrogen bottle to the fuel cell to provide raw materials for the fuel cell to generate electricity and generate the kinetic energy required for the drone. The storage space is powered by four 3000W hydrogen fuel cells placed in parallel. The hydrogen storage bottles on the U-shaped frames on both sides of the drone provide hydrogen for the hydrogen fuel cell to generate hydrogen. Due to the characteristics of the hydrogen fuel cell itself taking up a small space and the small weight of hydrogen; under the same power density, the volume occupied by the hydrogen fuel cell plus the hydrogen storage bottle and its own weight are much smaller than those of the lithium battery. Therefore, the use of hydrogen fuel cells can reduce its own parasitic power consumption while ensuring the power density, thereby improving the endurance. The reduced mass can increase the weight of the carried items to improve the transport efficiency of the drone. carrying capacity; and the amount of electricity stored in high-power-density lithium batteries is also huge. Limited by the current charging speed, when the battery is exhausted, it takes a while to recharge before it can be used again, which reduces the carrying efficiency; in addition, the application scenarios of carrying drones are usually outdoor. When the lithium battery of the drone is exhausted, there is generally no place to charge it, and the working time of the drone will be further shortened; while using hydrogen power, you can carry multiple hydrogen storage bottles at any time. When the hydrogen used for power generation in the hydrogen storage bottle is used up, you can open the Velcro to remove the hydrogen storage bottle and replace it with a hydrogen storage bottle filled with hydrogen to continue powering the battery. This not only solves the problem of long-term charging, but also can be used to fix hydrogen storage bottles of different sizes by wrapping the Velcro around different connecting rods of the U-shaped frame, which is easy to replace and improves work efficiency.
