[0002] When collecting water samples, in order to achieve fixed-point sampling, an unmanned aerial vehicle sampling device is generally used to fly to the sampling point for water sample collection. Most of the existing unmanned aerial vehicle sampling devices are specially used for sampling. When the sampling frequency is not high, there is a problem of waste of resources if a special unmanned aerial vehicle sampling device is purchased. At the same time, the sampling containers of the existing unmanned aerial vehicle sampling devices are mostly integrated on the fuselage of the unmanned aerial vehicle. This leads to an excessive load on the unmanned aerial vehicle during the sampling process after the weight of the sampling container increases, thereby increasing its power consumption, resulting in a shorter flight time when performing multi-point sampling, which is not conducive to the execution of the sampling task.

[0010] In one embodiment of the utility model, a filter screen is detachably provided at the bottom of the counterweight, and the filter screen wraps the output end of the micro water pump inside.

[0011] The beneficial effects of the utility model are:

[0022] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 A schematic structural diagram of a water sample collection device for an unmanned aerial vehicle provided by an embodiment of the utility model is shown, which includes a connecting bracket 2 detachably arranged on an unmanned aerial vehicle body 1, a wire retractor 3 is arranged at the bottom of the connecting bracket 2, the wire retractor 3 is connected to a water collection container 5 via a sling rope wound on the retractor and retractor end, the water collection container 5 is connected to a water collection device 7 via a water collection pipe 6, after the unmanned aerial vehicle body 1 carries the water collection container 5 and moves to the sampling point, the water collection container 5 can be thrown onto the water surface via the wire retractor 3, and the water collection device 7 sinks to a predetermined depth according to the length of the water collection pipe 6 for sampling, during this process, the water collection container 5 can float on the water surface, reducing the load of the unmanned aerial vehicle, avoiding the influence of the increased weight of the water collection container 5 on the end of the unmanned aerial vehicle body 1, and facilitating the execution of the sampling task when performing multi-point sampling.

[0025] like Figures 1-2 As shown, the connecting bracket 2 includes a bottom plate 21 and a fixing rod 22. The bottom plate 21 fits the bottom of the drone body 1. The two ends of the fixing rod 22 are connected to the bottom plate 21 to fix the drone body 1 in the middle.

[0026] In the above embodiment, the two ends of the fixing rod 22 are connected to the base plate 21 by bolts. When performing the sampling task, the bolts between the two ends of the fixing rod 22 and the base plate 21 can be removed to separate them. After the drone body 1 is fixed between the fixing rod 22 and the base plate 21, the bolts are tightened to complete the fixation. The advantage of adopting this solution is that when performing the sampling task, the water sample collection device can be installed on an ordinary drone for operation through the detachable connecting bracket 2, avoiding the problem of waste of resources caused by purchasing a special drone sampling device when the sampling frequency is not high.

[0027] The connecting bracket 2 can be made of light-weight and high-strength plastic or hollow metal to reduce weight.

[0028] like Figure 1 , 3 As shown in FIG. 4 , a water intake pipe 6 is detachably provided between the end 52 of the water intake container 5 and the water extractor 7 . The water intake pipe 6 is used to connect the water extractor 7 with the water intake container 5 , and the water intake pipe 6 can be set to any length.

[0029] Specifically, a quick connector is provided at the end 52 of the water intake container 5 and at the opposite side of the water intake device 7, and both ends of the water intake pipe 6 are respectively connected to the quick connector.

[0030] In one example of the above embodiment, a water intake pipe 6 of corresponding length is selected according to the water depth required for sampling, and the two ends of the water intake pipe 6 are respectively connected to the end 52 of the water intake container 5 and the quick connector provided on the water collector 7. After the drone body 1 throws the water intake container 5 onto the water surface, the water collector 7 sinks to the corresponding depth according to the length of the water intake pipe 6.

[0031] In a preferred embodiment, a hose reel may be provided, and the water intake pipe 6 is wound around the hose reel. When the length of the water intake pipe 6 needs to be adjusted, the length of the water intake pipe 6 can be adjusted by pulling the water intake pipe 6 .

[0032] like Figures 1 to 4 As shown, one end of a suspension rope 4 is wound around the reel of the wire retractor 3 , and the other end of the suspension rope 4 is connected to the head end 51 of the water collection container 5 .

[0033] In one example, the reel 3 is a winch or a winder, and the height of the water intake container 5 is adjusted by winding or unwinding the reel.

[0034] like Figure 5 As shown, in order to control the sampling process, a control device 8 and a remote control device 9 can also be provided, wherein an independent cavity is provided inside the head end 51 of the water collection container 5, and the control device 8 is provided inside the cavity. The control device 8 is communicatively connected with the retractable wire retractor, the micro water pump 72 and the drone body 1, and the control device 8 is communicatively connected with the remote control device 9.

[0035] Specifically, the control device 8 includes a controller a81 and a signal transceiver a82. The controller a81, the signal transceiver a82 and the power supply 83 are sequentially arranged inside the cavity. The signal input end of the controller a81 is communicatively connected to the signal output end of the signal transceiver a82. The power supply 83 is used to power the controller a81 and the signal transceiver a82. The remote control device 9 includes a controller b91 and a signal transceiver b92. The signal output end of the controller b91 is communicatively connected to the signal input end of the signal transceiver b92. The signal output end of the signal transceiver b92 is communicatively connected to the signal input end of the signal transceiver a82. The signal output end of the controller a81 is communicatively connected to the signal input ends of the retractable wire retractor 3, the micro water pump 72 and the drone body 1 respectively.

[0036] In one example, the water collection container 5 is thrown onto the water surface, and the sampling personnel sends control instructions to the control device 8 through the remote control device 9 to control the drone body 1. After adjusting the position of the drone body 1, the control signal is sent through the controller b91, and the signal transceiver b92 sends the control signal to the signal transceiver a82. After receiving the control signal, the controller a81 controls the line retractor 3 to adjust the height of the water collection container 5 to complete the operation of throwing the water collection container 5 onto the water surface.

[0037] In another example, the water collection container 5 is controlled to draw water, and the sampling personnel sends a control signal through the controller b91, and the signal transceiver b92 sends the control signal to the signal transceiver a82. After receiving the control signal, the controller a81 controls the micro water pump 72 to turn on, and the suction end of the micro water pump 72 draws water into the interior of the water collection container 5 through the water collection pipe 6.

[0038] like Figures 1 to 4 As shown, the water dispenser 7 includes a counterweight 71 and a micro water pump 72. A cavity is provided at the bottom of the counterweight 71, and the micro water pump 72 is arranged in the cavity. The output end of the micro water pump 72 is connected to one end of the water intake pipe 6 through a quick connector, and the suction end of the micro water pump 72 is arranged outside the counterweight 71.

[0039] The counterweight 71 facilitates the water extractor 7 to sink underwater for sampling.

[0040] In a preferred embodiment, a filter screen 73 is detachably provided at the bottom of the counterweight 71, such as by a threaded or snap-on connection, and the filter screen 73 wraps the output end of the micro water pump 72 inside thereof to protect the micro water pump 72 and prevent impurities from clogging the micro water pump 72.

[0041] In one example, after the water collection container 5 is thrown onto the water surface, the water collection container 5 is kept in a vertical state by pulling the water collection pipe 6 during the sinking process of the water collection device 7 .

[0042] In another example, during the process of drawing water from the water collection container 5, if the water collection container 5 sinks, it can be lifted by the drone body 1 to keep its relative position above the water surface. At the same time, due to the existence of buoyancy, the process of the drone body 1 lifting the water collection container 5 has little effect on the load of the drone body 1, and can still avoid affecting the flight time.

[0043] It should be noted that a one-way valve should be provided at the water inlet at the end 52 of the water collection container 5 to prevent water from flowing back after the micro water pump 72 stops running. At the same time, the water collection container 5 is provided with an air hole near the head end 51 of the water collection container 5 to maintain the internal and external air pressure balance during the process of drawing in water samples. Since the above structure belongs to conventional technical means known to technical personnel in this field, its specific working principle will not be repeated here.

[0044] Specifically, when performing sampling tasks, the water sample collection device can be installed on an ordinary drone through a detachable connecting bracket 2 for operation, avoiding the problem of waste of resources caused by purchasing a special drone sampling device when the sampling frequency is not high. After the drone body 1 carries the water collection container 5 and moves to the sampling point, the water collection container 5 can be thrown onto the water surface through the retractor 3, and the water collection device 7 sinks to a predetermined depth according to the length of the water collection pipe 6 for sampling. In this process, the water collection container can float on the water surface, reducing the load of the drone and avoiding the increase in the weight of the water collection container. The impact on the endurance time is avoided, which is beneficial to the execution of sampling tasks when performing multi-point sampling.

[0045] It should be noted that the specific models and specifications of the retractable wire device 3, micro water pump 72, controller a81, controller b101, signal transceiver a82, signal transceiver b102 and power supply 83 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0046] The power supply and principles of the cable retractor 3, micro water pump 72, controller a81, controller b101, signal transceiver a82, signal transceiver b102 and power supply 83 are clear to those skilled in the art and will not be described in detail here.

[0047] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
