Description

Technical Field

[0001] This application relates to the technical field of water quality sampling, and in particular to an automatic quantitative water sampling device mounted on a drone. Background Technology

[0002] A drone-based water sampling device is a device that collects water samples by controlling a drone. It has a simple structure and is easy to operate, but with the development of science and technology, people have increasingly higher requirements for water sampling devices.

[0003] A search revealed Chinese Patent Publication No. CN213180833U, which discloses a water sampling device for a drone. The device includes a drone, a slide rail on the lower inner surface of the drone, a slot fixedly mounted on the front outer surface of the drone, and a limiting hole on the front outer surface of the slide rail. This utility model's water sampling device for a drone, through its slide rail, sliding opening, limiting hole, sliding rod, water bucket, and connecting rod, allows for easy storage of the water bucket via the slot. Furthermore, the slide rail, limiting hole, sliding rod, and sliding opening facilitate sliding adjustment and fixing via the limiting post, and also allow for easy changing of the water bucket size. Additionally, the water bucket and connecting rod facilitate rotation of the water bucket, allowing the bucket to tilt during drone water collection using the downward pressure of the drone and the buoyancy of the water, making it easier for users to collect water. This design enhances usability and presents a promising future for its application.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In actual water sampling operations, the amount of water taken each time is basically the same, which cannot guarantee the accuracy of the test data. The above-mentioned solutions cannot achieve the effect of automatic quantitative water extraction, which affects the amount of water taken each time and easily leads to inaccurate test data. Utility Model Content

[0005] To facilitate automatic quantitative water sampling, this application provides an automatic quantitative water sampling device mounted on a drone.

[0006] This application provides an automatic quantitative water sampling device for UAV-mounted water quality sampling, which adopts the following technical solution: it includes a bidirectional threaded rod and a base plate. The outer surface of the bidirectional threaded rod is threadedly connected to two clamping members. One of the clamping members has a screw rotatably connected to its upper surface. The outer surface of the screw is threadedly connected to a threaded block. The outer surface of the threaded block is slidably connected to a limiting member. The bottom surface of the limiting member is fixedly connected to the upper surface of the corresponding clamping member. A sensing block is fixedly connected to the left side of the threaded block. A pointer is fixedly installed on the outer surface of the sensing block. A bottle is provided on the right side of the bidirectional threaded rod. The outer surface of the bottle has equidistant graduations.

[0007] Optionally, the upper surface of the base plate is fixedly connected with support plates arranged at equal intervals, and the upper surface of each support plate is fixedly connected with a mounting block. The outer surface of the bidirectional threaded rod is rotatably connected to the inner wall of the corresponding mounting block.

[0008] Optionally, a guide rod is provided on the right side of the bottle body, and the outer surface of the guide rod is fixedly connected to the inner wall of the corresponding mounting block.

[0009] Optionally, a motor is fixedly installed on the upper surface of the base plate, and a winding drum is fixedly connected to the output shaft of the motor. A water pumping pipe is provided on the outer surface of the winding drum.

[0010] Optionally, a steel pipe is rotatably connected to the end of the water pump pipe away from the motor, and a pump body is fixedly connected to the other end of the steel pipe. A delivery pipe is fixedly connected to the output end of the pump body, and the outer surface of the delivery pipe is in contact with the inner wall of the bottle.

[0011] Optionally, the winding drum is provided with uprights on both the front and back sides, the bottom surface of each upright is fixedly connected to the upper surface of the base plate, the output shaft of the motor is rotatably connected to the inner wall of the corresponding upright, and the outer surface of the steel pipe is fixedly connected to the inner wall of the corresponding upright.

[0012] Optionally, a drone body is provided above the base plate, and a support frame is fixedly connected to the bottom surface of the drone body. Two connecting rods are fixedly connected to the outer surface of the support frame, and the bottom end of each connecting rod is fixedly connected to the upper surface of the base plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model incorporates components such as a bidirectional threaded rod, a clamping member, a screw, a sensing block, and a pointer. By rotating the bidirectional threaded rod, the clamping member moves relative to the bottle, achieving a clamping effect. At this time, the sensing block contacts the bottle. Rotating the screw causes the threaded block to rise and fall, which in turn causes the sensing block to rise and fall. The sensing block, in turn, causes the pointer to rise and fall. The pointer is aligned with the scale on the bottle surface. When water is injected into the bottle, the sensing block detects the position of the horizontal line inside the bottle, thus starting and stopping the water injection. This allows the device to automatically dispense water in a quantitative manner and facilitates adjustment of the water volume.

[0015] 2. This utility model comprises components such as a winding drum, a suction pipe, a steel pipe, a pump body, and a delivery pipe. The rotation of a motor drives the winding drum to rotate, which in turn drives the suction pipe to wind up. The pump body then pumps the sampled liquid through the suction pipe to the inside of the steel pipe, then through the steel pipe to the pump body, and finally through the pump body to the inside of the delivery pipe, and finally to the inside of the bottle. After sampling, the reverse rotation of the motor drives the winding drum to wind up the suction pipe. Because the steel pipe is made of steel and is rotatably connected to both the suction pipe and the winding drum, the rotation of the winding drum effectively winds up the suction pipe, thus enabling the device to easily sample and extract water.

The threaded block 5 raises and lowers the sensing block 6, and the sensing block 6 raises and lowers the pointer 7. The pointer 7 is matched with the scale 9 on the surface of the bottle body 8. Then, the drone body 21 moves to the designated position. The motor 14 drives the winding drum 15 to rotate. The winding drum 15 extends the water extraction pipe 16 until it extends into the sampling water. The sampling water is extracted by the pump body 18, steel pipe 17 and water extraction pipe 16. The sampling water is delivered to the inside of the bottle body 8 by the pump body 18 and delivery pipe 19. The sensing block 6 senses the liquid position inside the bottle body 8. When the liquid level is reached, the sensing block 6 causes the pump body 18 to stop pumping water, achieving the effect of quantitative water sampling.
