[0002] A surveying and mapping drone is a drone that can perform mapping in the air. In order to increase its functionality, some surveying and mapping drones will also be equipped with a sampling function. For example, in the patent with application number 202221370599.4 and name "A drone water sample collector", a liquid pump is used to make the submerged liquid suction tube draw water out through the filter nozzle, and then discharge it through the liquid outlet tube and collect it in the sampling bottle. Although this method can collect water samples, the length of the liquid suction tube is limited and its usable length cannot be adjusted, resulting in the depth of the drone being limited when collecting water samples. It is impossible to extract water samples to the required depth according to different needs, which reduces the applicability of sampling. For this reason, we propose a surveying and mapping drone with a sampling function that has strong applicability. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3 A mapping drone with a sampling function is shown, including a drone body 101, a sampling pipe is arranged at the bottom end of the drone body 101, the sampling pipe includes a rotating tube 201 and a suction pipe 202, the suction pipe 202 is a hard hose, which can be rotated and wound, but will not be deformed, a base 200 is arranged at the bottom end of the drone body 101, the rotating tube 201 is rotatably connected to the bottom end of the base 200, the suction pipe 202 is wound around the outer wall of the rotating tube 201, and one end of the suction pipe 202 is fixedly connected with the outer wall of the rotating tube 201 through insertion, and the rotating tube 201 is rotated at the bottom end of the base 200 to reel or release the suction pipe 202 on the outer wall of the rotating tube 201, so that when the drone collects water samples, the length of the suction pipe 202 submerged in the water can be adjusted according to the sampling requirements, so that the drone can collect water samples at different depths, thereby improving the applicability of the drone for water sample collection.

[0020] Among them, the outer wall of the rotating tube 201 is fixedly sleeved with multiple limiting rings 500, and the suction tube 202 is wound and arranged between the multiple limiting rings 500. A rotating mechanism is set at the top of one of the limiting rings 500. There are two limiting rings 500, which can stably limit the suction tube 202 wrapped around the outer wall of the rotating tube 201 to prevent the wrapped suction tube 202 from scattering.

[0021] Preferably, a fixing plate 301 is fixedly connected to the top of the base 200, and a guide hole 302 is provided on one side of the fixing plate 301. The outer wall of the suction tube 202 is movably connected with the inner wall of the guide hole 302, and a plurality of ball grooves 304 are provided on the inner wall of the guide hole 302. Rolling balls 305 are movably connected to the inner walls of the plurality of ball grooves 304. A counterweight mechanism is provided at one end of the suction tube 202. The guide hole 302 is used to limit and guide the suction tube 202, so that when the rotating tube 201 rotates to release the suction tube 202, the suction tube 202 can be stably inserted from the guide hole 302 and immersed in water for sampling. Since the rolling ball 305 is always rolling in the ball groove 304, the suction tube 202 can move more smoothly in the guide hole 302, thereby ensuring that the rotation of the rotating tube 201 can make the suction tube 202 stably move in the guide hole 302.

[0022] Furthermore, the counterweight mechanism includes a counterweight sleeve 402, and the end of the suction tube 202 is fixedly sleeved with a fixing ring 401. The inner wall of the counterweight sleeve 402 is threadedly connected to the outer wall of the fixing ring 401, and the inner wall of the counterweight sleeve 402 is provided with a filter screen 403. The fixing ring 401 has a certain weight when entering the counterweight sleeve 402, so that the fixing ring 401 and the counterweight sleeve 402 always have a tendency to drive the suction tube 202 to be inserted out of the guide hole 302, that is, when the rotating tube 201 rotates to release the suction tube 202, the suction tube 202 can be stably inserted out of the guide hole 302, and at the same time, under the counterweight action of the fixing ring 401 and the counterweight sleeve 402, the end of the suction tube 202 can be stably immersed in the water, ensuring that the suction tube 202 is more stable when collecting water samples at different depths. At the same time, the filter screen 403 can filter the water drawn into the suction tube 202 to prevent impurities in the water from entering the suction tube 202.

[0023] The bottom end of the base 200 is provided with a connecting hole 601, the rotating tube 201 is rotatably arranged on the inner wall of the connecting hole 601, a suction pump 602 is installed inside the base 200, a sample storage chamber 603 is provided inside the base 200, the output end of the suction pump 602 is fluidically connected to the sample storage chamber 603, and the input end of the suction pump 602 is fluidically connected to the connecting hole 601. When the rotating tube 201 rotates to release the suction tube 202, the suction tube 202 is submerged in the water along with the fixing ring 401 and the counterweight sleeve 402. When the suction tube 202 sinks to the desired position, the suction tube 202 is released. After being placed, the rotating tube 201 no longer rotates. At this time, the suction pump 602 works, so that a negative pressure is generated inside the connecting hole 601. Then, with the connection between the rotating tube 201 and the suction tube 202, the water can be sequentially passed through the suction tube 202, the suction tube 202, the connecting hole 601 and drawn into the sample storage chamber 603 for storage. A pressure relief valve is arranged inside the sample storage chamber 603 to balance the pressure inside the sample storage chamber 603. A sealing filler is arranged between the outer wall of the rotating tube 201 and the inside of the connecting hole 601 to ensure the sealing between the rotating tube 201 and the connecting hole 601.

[0024] Furthermore, the rotating mechanism includes an outer gear ring 501, the top of the outer gear ring 501 is fixedly connected with the outer gear ring 501, the outer wall of the outer gear ring 501 is meshed with a gear 502, and a servo motor 503 is installed inside the base 200, and the output end of the servo motor 503 is transmission-connected with the top of the gear 502, and the servo motor 503 can drive the gear 502 to rotate, and the meshing outer gear ring 501 can be driven to rotate, so that the limit ring 500 rotates, and the rotating tube 201 rotates, and the servo motor 503 and the suction pump 602 are respectively electrically connected to the external power supply through an external switch, which is convenient for the operator to control the servo motor 503 and the suction pump 602, thereby improving the stability and convenience of the operation of the servo motor 503 and the suction pump 602.
