Description

Technical Field

[0001] The utility model relates to the technical field of water bottles for drones, and in particular to a water bottle for taking water samples by drones. Background Art

[0002] In water environment monitoring, the first step in monitoring samples is sampling. In the actual sampling process, for sampling points far offshore, sampling personnel are usually required to take boats and other tools to reach the sampling points, and then use plastic bottles or buckets to take samples. This has defects such as complicated operation process, high labor costs, high risk of human operation, low sampling efficiency, and difficulty in ensuring sample quality.

[0003] Existing patents use drones equipped with automatic sampling and water collection equipment to collect samples. The drone flies to a sampling point far from the shore and hovers above the water surface. The automatic sampling and water collection equipment suspends the water bottle to a suitable depth below the water surface for sampling. However, in eutrophic rivers and lakes, aquatic plants grow too lushly and are easily collected during the drone water collection process. These impurities will not only block the water collection equipment, but may also interfere with subsequent water quality monitoring results, causing data distortion. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a water sampling bottle for drone water sampling, which is used to solve the above problems.

[0005] The utility model is achieved in this way:

[0006] A water sampling bottle for a drone to take water samples, comprising:

[0007] A water intake assembly includes a bottle body, a lifting elastic cover, and a one-way valve. The bottom of the bottle body is provided with an inner recess, an inner hole is opened at the bottom axis of the inner recess, an empty tube is provided inside the bottle body, one end of the empty tube is connected to the top of the bottle body, and the other end of the empty tube is extended to the bottom axis of the inner hole. A bracket is provided between the inner side wall of the inner hole and the empty tube. The lifting elastic cover is provided at the bottom of the inner recess, and the one-way valve is provided on the side of the top of the bottle body away from the axis.

[0008] A top cover, which is detachably arranged on the top of the bottle body;

[0009] The filter assembly comprises a conical filter screen which is detachably arranged at the bottom of the bottle body and a counterweight block is arranged at the bottom of the conical filter screen.

[0010] In one embodiment of the present invention, the top cover is hemispherical, a plurality of filter holes are provided on the surface of the top cover, and a rope threading hole is provided at the top center of the top cover.

[0011] In one embodiment of the present invention, the lifting elastic cover includes a plurality of telescopic rods arranged on the top wall of the inner recess, a spring is arranged inside the telescopic rod, the telescopic rod and the spring constitute an elastic telescopic column, a bottom cover is provided at the bottom of the output rod of the telescopic rod, a hanging rope is provided at the top axis of the bottom cover, the hanging rope passes through the empty tube and the rope hole in sequence to the top of the water bottle and is connected to the drone.

[0012] In one embodiment of the present invention, a sealing ring A is provided at the top edge of the bottom cover, and a sealing ring B is provided at a position where the top wall of the inner recess contacts the sealing ring A.

[0013] In one embodiment of the present invention, the diameter of the bottom cover is smaller than the aperture of the inner recess.

[0014] In one embodiment of the present invention, there are four elastic telescopic columns, which are evenly distributed between the bottom cover and the inner recessed portion with the inner hole axis as the center of the circular array. When the elastic telescopic column is fully contracted, the bottom cover is retracted into the interior of the inner recessed portion, and the sealing ring A and the sealing ring B are in conflict with each other. When the elastic telescopic column is fully extended, the bottom cover is pushed out of the inner recessed portion.

[0015] In an embodiment of the present invention, the direction of the one-way valve is from the inside of the bottle body to the outside.

[0016] The beneficial effects of the present invention are as follows: the water bottle is composed of a water intake component and a filtering component. When the water bottle is put into water, the counterweight block at the bottom not only ensures that the water bottle always maintains a vertical direction during the water intake process, but also, through its unique conical design, the water bottle can sink into the water more stably than a flat-bottom design, effectively avoiding the bottle body from falling sideways due to factors such as aquatic plants and water waves, thereby ensuring smooth filtration and water intake. In addition, the filtering component effectively prevents aquatic plants and algae from entering the bottle body, avoiding the potential interference of these impurities on subsequent water quality monitoring results, and ensuring the purity of water sample collection and the accuracy of monitoring results.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[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 rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, the utility model provides a water sampling bottle for drone water sampling, including a water sampling component 20, which consists of a bottle body 21 and a lifting elastic cover 22 arranged at the bottom. A one-way valve 23 is arranged on the top of the bottle body 21, and a filter component 40 is arranged at the bottom of the water sampling component 20, which not only provides a coarse filtration function, but also has a counterweight. One end of the suspension rope 30 is fixed to the bottom of the lifting elastic cover 22, and the other end passes through the bottle body 21 and is connected to the drone above. During the sampling process, the drone flies to the designated sampling point. After the water bottle enters the water, the buoyancy and the elastic force of the lifting elastic cover 22 open the bottom cover 2202 to allow the water sample to enter. The conical design of the filter component 40 can help the water bottle quickly enter the water, effectively avoid the interference of aquatic plants and algae, and can also perform coarse filtration, thereby improving the sampling efficiency and sample quality.

[0025] In this embodiment, the water intake assembly 20 includes a bottle body 21, a lifting elastic cover 22 and a one-way valve 23. The bottom of the bottle body 21 is provided with an inner recess 2101, and an inner hole 2102 is opened at the bottom axis center of the inner recess 2101. An empty tube 2104 is provided inside the bottle body 21. One end of the empty tube 2104 is connected to the top of the bottle body 21, and the other end of the empty tube 2104 is connected to the bottom axis center of the inner hole 2102. A bracket 2103 is provided between the inner side wall of the inner hole 2102 and the empty tube 2104. The lifting elastic cover 22 is provided at the bottom of the inner recess 2101, and the one-way valve 23 is provided on the side of the top of the bottle body 21 away from the axis center. The medium flow direction of the one-way valve 23 is from the inside of the bottle body 21 to the outside. The one-way valve 23 ensures that water flows into the water intake bottle normally without being affected by atmospheric pressure when flowing in from the inner hole 2102.

[0026] Among them, the lifting elastic cover 22 includes a plurality of telescopic rods 2201 arranged on the top wall of the inner recess 2101, and a spring 22011 is arranged inside the telescopic rod 2201. The telescopic rod 2201 and the spring 22011 form an elastic telescopic column. The bottom of the output rod of the elastic telescopic column is provided with a bottom cover 2202, and the top axis of the bottom cover 2202 is provided with a hanging rope 30. The hanging rope 30 passes through the empty tube 2104 and the rope hole 11 in turn to the top of the water bottle and is connected to the drone. When the hanging rope 30 is not under force, the bottom cover 2202 is always pushed out by the elastic telescopic column, so that the bottle body 21 is in an open state.

[0027] Furthermore, a sealing ring A2203 is provided at the top edge of the bottom cover 2202, and a sealing ring B2204 is provided at the position where the top wall of the inner recess 2101 contacts the sealing ring A2203, so that the bottom cover 220221 is better sealed when it contacts the bottom of the inner recess 210123, thereby preventing the collected water sample from flowing out.

[0028] Furthermore, the diameter of the bottom cover 2202 is smaller than the aperture of the inner recess 2101 , so that the bottom cover 2202 can be completely retracted into the inner recess 2101 .

[0029] In a preferred embodiment, there are four elastic telescopic columns, which are evenly distributed between the bottom cover 2202 and the inner recess 2101 with the axis of the inner hole 2102 as the center of the circular array. During underwater sampling, the four elastic telescopic columns can make the bottom cover 2202 and the top wall of the inner recess 2101 uniformly stressed in four directions when they collide, thereby preventing the telescopic rod 2201 from getting stuck and unable to retract. When the elastic telescopic columns are fully retracted, the bottom cover 2202 retracts into the interior of the inner recess 2101, and the sealing ring A2203 and the sealing ring B2204 collide with each other. When the elastic telescopic columns are fully extended, the bottom cover 2202 is pushed out of the inner recess 2101.

[0030] As a preferred embodiment, the bottle body 21 is made of polyethylene plastic, which is an inert material and can avoid reacting with the sample to be tested.

[0031] In this embodiment, the filter assembly 40 includes a conical filter screen 41, which is threadedly connected to the bottom of the water intake assembly 20. A counterweight block 42 is provided at the bottom of the conical filter screen 41, which can enable the water bottle to enter the water quickly and stably compared to the flat bottom design. At the same time, the design of the counterweight block 42 ensures that the water bottle maintains a vertical direction during underwater sampling to prevent tilting or flipping due to water flow fluctuations. When the water sample flows through the conical filter screen 41, large particles of weeds, algae and other impurities can be filtered out, thereby improving the sampling efficiency.

[0032] In this embodiment, the top cover 10 is threadedly connected to the top of the bottle body 21. The top cover 10 is hemispherical. A plurality of filter holes are provided on the surface of the top cover 10. A rope hole 11 is provided on the top of the top cover 10 for the hanging rope 30 to pass through. The filter holes can prevent impurities from passing through the empty tube 2104 into the inner recess 2101 and finally entering the bottle body 21. The hemispherical design can reduce the situation where impurities such as water plants are hung on the top of the water bottle when the water bottle is recycled.

[0033] Specifically, the working principle of the water bottle for taking water samples by drone is as follows: the water bottle is connected to the drone through the hanging rope 30. When it is hung in the air, the weight of the water bottle causes the bottom cover 2202 to squeeze the telescopic rod 2201, and the bottom cover 2202 is tightly in contact with the top wall of the inner recess 2101 to form a sealing structure. Once the water bottle sinks into the water, the buoyancy effect causes the hanging rope 30 to relax, reducing the tension on the bottom cover 2202, and the telescopic rod 2201 is unfolded, pushing the bottom cover 2202 out of the inner recess 2101. After the water sample is filtered by the conical filter 41, it flows into the bottle body 21 through the inner hole 2102. At the same time, the single The valve 23 ensures that the water sample flows in normally without being affected by atmospheric pressure. After the sampling is completed, the drone is launched into the air by remote control, and the suspension rope 30 applies tension to the bottom cover 2202. Combined with the dead weight after being filled with water, the telescopic rod 2201 is completely retracted, and the bottom cover 2202 is retracted into the inner recess 2101. The sealing ring A2203 is in close contact with B to form a sealing structure, which effectively prevents the loss of water samples. The above structure solves the problem that the existing technology is prone to collecting algae and aquatic plants in the water when taking water in eutrophic rivers and lakes, causing blockage of the water intake equipment, interference with subsequent water quality monitoring results, and data distortion.

[0034] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
