[0002] At present, due to the advantages of drones such as strong maneuverability, high wireless operability, strong environmental adaptability and high efficiency, the use of drones for sample collection has gradually become a commonly used emerging technology for water quality monitoring.

[0003] When existing water sample collection drones collect water samples, the drones need to float close to the water surface to collect water samples. However, due to improper operation and external environmental factors such as strong winds, the drones are at risk of falling into the water and being damaged. For this reason, we propose a drone that is convenient for collecting samples. Utility Model Content

[0004] The purpose of the utility model is to provide a drone that is convenient for collecting samples. The utility model has the advantage that the drone can float in the air when collecting water samples, thereby avoiding the drone from falling into the water and being damaged due to improper operation and external environmental factors such as strong winds. The utility model solves the problem that when collecting water samples, the drone needs to float close to the water surface to collect water samples, but due to improper operation and external environmental factors such as strong winds, the drone is at risk of falling into the water and being damaged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drone for convenient sample collection, comprising a drone body and a sampling box, wherein support frames are symmetrically fixedly installed at both sides of the lower surface of the drone body, a horizontal plate is fixedly installed between the two support frames, and the sampling box is located on the upper surface of the horizontal plate, floating airbags are fixedly installed inside the two support frames near the lower surface, an air pump is fixedly installed on the upper surface of the horizontal plate near the rear surface, an electromagnetic three-way valve is fixedly connected to the end of the air pump output pipe, an air pipe is fixedly connected to the lower surface of the electromagnetic three-way valve, and both ends of the air pipe are respectively fixedly connected to the outer surfaces of the two floating airbags.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model achieves the effect that the drone can float in sleep when collecting water samples by arranging a drone body, a support frame, a floating airbag, an air pump and an electromagnetic three-way valve, thereby avoiding the drone from falling into the water and being damaged due to improper operation and external environmental factors such as strong winds. Before preparing to collect water samples, the air pump works and fills air into the floating airbag to increase the volume of the floating airbag. When collecting water samples, the drone body can float on the water surface using the floating airbag, and then collect water samples through a sampling box, thereby avoiding the drone from falling into the water and being damaged due to improper operation and external environmental factors such as strong winds. After the water sample collection is completed, the electromagnetic three-way valve works to discharge the air inside the floating airbag, thereby reducing the volume of the floating airbag and reducing the air resistance of the drone body during flight.

[0015] 2. The utility model achieves the effect of facilitating the fixing and disassembly of the sampling box by providing a socket, a fixing block, a through hole, a sliding rod and a coil spring. When the sampling box is placed on the horizontal plate, one end of the sliding rod is inserted into the socket, thereby fixing the sampling box on the horizontal plate. When disassembling the sampling box, it is only necessary to separate the sliding rod and the socket, and the elastic force of the coil spring can prevent the sliding rod and the socket from automatically separating.

[0016] 3. The utility model achieves the effect of facilitating the collection of multiple water samples and classified storage by arranging a sampling pump, a fixing plate, a slot, a branch pipe, a solenoid valve, a sampling pipe and a water injection pipe. The sampling bottle is inserted into the slot, and each sampling bottle corresponds to the solenoid valve one by one, and the corresponding water injection pipe is inserted into the sampling bottle. When sampling, the sampling pump discharges the water sample into the branch pipe, and the corresponding solenoid valve is opened to allow the water sample to be injected into the corresponding sampling bottle.

[0017] 4. The utility model achieves the effect of preventing the water sample in the sampling bottle from splashing out due to shaking by arranging a rubber plug and a vent hole. The rubber plug is inserted into the bottle mouth of the sampling bottle to prevent the water sample in the sampling bottle from splashing out due to shaking, and the vent hole allows the air in the sampling bottle to be discharged when the water sample is injected into the sampling bottle.
