Technical Field

[0001] The utility model relates to the technical field of drones, in particular to a drone parachute capable of calculating wind speed. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self - contained program control device. As an emerging intelligent industry, drones initially had a huge market demand in the military field. In recent years, with the development and progress of technology, the application of drones has gradually extended from the military field to the civilian field, and the application scope has been continuously broadened. They have become increasingly mature in industries such as consumption, plant protection, power, security, and surveying and mapping. When a drone falls, it will cause harm to people or objects, so a drone parachute is needed. However, most of the existing drone parachutes do not have the effect of calculating wind speed when in use. Therefore, there is a particular need for a drone parachute capable of calculating wind speed.

[0003] Because when a drone falls, it usually opens the parachute to protect people or objects on the ground. However, most of the drone parachutes on the market do not have the function of measuring wind speed, which makes it difficult to measure the speed of the drone when it is descending during landing, not facilitating the subsequent improvement of the drone parachute, and is not conducive to the use of a drone parachute capable of calculating wind speed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drone parachute capable of calculating wind speed to solve the problem raised in the above background art. That is, when a drone falls, it usually opens the parachute to protect people or objects on the ground. However, most of the drone parachutes on the market do not have the function of measuring wind speed, which makes it difficult to measure the speed of the drone when it is descending during landing, not facilitating the subsequent improvement of the drone parachute, and is not conducive to the use of a drone parachute capable of calculating wind speed.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drone parachute capable of calculating wind speed, including a parachute, a snap - on wind speed measuring mechanism is arranged on the outer surface of the parachute, and a fire - proof, anti - corrosion and high - temperature - resistant coating is wrapped on the outer surface of the parachute;

[0006] The snap - type wind speed measuring mechanism includes an anemometer, a clamping post, a through - hole, a square groove, a supporting piece, a square column, a circular groove, a spring and a clamping block. The inner surface of the parachute is fixedly connected with an anemometer, and the inner surface of the parachute is fixedly connected with a clamping post. A through - hole is formed on the outer surface of the clamping post, and a square groove is formed on the outer surface of the clamping post. The outer surface of the anemometer is fixedly connected with a supporting piece, and a square column is fixedly connected to one side surface of the supporting piece. A circular groove is formed on one side surface of the square column, a spring is fixedly connected to the inner surface of the circular groove, and a clamping block is fixedly connected to one end surface of the spring.

[0007] Preferably, the clamping posts are annularly distributed around the center point of the anemometer, and the clamping block and the through - hole form a snap - fit structure.

[0008] Preferably, one end of the spring is welded to the inner side of the square column, and the other end of the spring is welded to one side of the clamping block.

[0009] Preferably, the fire - proof, anti - corrosion and high - temperature - resistant coating includes high - chlorinated polyethylene resin paint, ammonium polyphosphate paint, silicone paint, inorganic zinc - rich paint and polyurethane paint. The fire - proof, anti - corrosion and high - temperature - resistant coating material is mixed with high - chlorinated polyethylene resin paint, the fire - proof, anti - corrosion and high - temperature - resistant coating material is mixed with ammonium polyphosphate paint, the fire - proof, anti - corrosion and high - temperature - resistant coating material is mixed with silicone paint, the fire - proof, anti - corrosion and high - temperature - resistant coating material is mixed with inorganic zinc - rich paint, and the fire - proof, anti - corrosion and high - temperature - resistant coating material is mixed with polyurethane paint.

[0010] Preferably, the high - chlorinated polyethylene resin paint is composed of high - chlorinated polyethylene resin and synthetic resin, and the ammonium polyphosphate paint is composed of ammonium orthophosphate and various ammonium polyphosphates.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this kind of UAV parachute capable of calculating wind speed, through the setting of the anemometer, clamping post, through - hole, square groove, supporting piece, square column, circular groove, spring and clamping block, during use, first align the square column on the anemometer with the square groove opened on the clamping post, then press the clamping block. At this time, the clamping block will compress the spring so that the clamping block is in the circular groove, and then push the supporting piece until the compressed spring snaps into the through - hole. In this way, the function of measuring wind speed is added to the parachute. Through the above settings, it solves the problem in the prior art that when a UAV falls, it usually opens the parachute to protect people or items on the ground, but most UAV parachutes on the market do not have the function of measuring wind speed. This makes it difficult to measure the speed of the UAV during descent when it lands, which is not convenient for the subsequent improvement of the UAV parachute and is not conducive to the use of a UAV parachute capable of calculating wind speed, and achieves the effect of being able to measure wind speed.
