Description

Technical Field

[0001] The utility model relates to the technical field of water sample collection equipment, in particular to a water sample collector. Background Art

[0002] Water sample sampling refers to extracting a part of water from the target water area as a sample, and then detecting and analyzing the water sample.

[0003] In the prior art, when performing water sample sampling operations, the sampling equipment (including the control system and the water sample collector) is usually mounted on a drone, and the sampling equipment is transported to the target water area by remotely controlling the drone, and then the sampling equipment is moved to the target water area by the drone for sampling. However, this operation method requires mounting the sampling equipment on the drone, which makes it inconvenient to operate when additional equipment for monitoring the water environment (such as a camera terminal) needs to be mounted.

[0004] More critically, almost all existing water sample collectors use a sampling tube for adsorption sampling. During use, the mouth of the sampling tube or the end of its connecting tube is immersed below the water surface, and then the control system is turned on to pump and suck the water sample. However, this kind of water sample collector can only sample at a certain point in the water area, cannot complete linear area sampling, and cannot complete sampling quickly. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a water sample collector for solving the technical problems mentioned in the background art.

[0006] The utility model adopts the following technical scheme: a water sample collector, including two brackets, two cross bars are installed between the two brackets, a sampling structure is provided on the brackets, the sampling structure includes a number of reserved holes, the number of reserved holes are opened on the brackets, a sampling tube is threadedly connected in the reserved holes, when the sampling tube is tightened by means of the thread, the lowermost end of the sampling tube is flush with the lowermost end of the bracket, a partition is fixedly connected inside the sampling tube, a number of leakage holes are evenly opened on the surface of the partition, a sponge block is arranged inside the sampling tube, and the sponge block is located on the partition.

[0007] By adopting this scheme, the sampling tube can be directly and quickly installed on the bracket of the drone. The bracket is the landing gear of the drone. The drone flies to the target water area, and by immersing the position where the sampling tube is installed at the bottom of the bracket into the water area, the water sample is sucked by means of the sponge block, thus freeing up space for carrying other equipment on the drone.

[0008] Further, a round cover is threadedly connected to the upper end of the sampling tube, the lower end of the round cover abuts against the sponge block, and the round cover is of a hollow structure.

[0009] Further, a positioning plate is fixedly connected to the arc surface of the sampling tube. When the sampling tube is tightened on the bracket, the positioning plate just contacts the bracket, which facilitates positioning between the sampling tube and the bracket.

[0010] Further, several of the reserved holes are equally divided into two groups, and several reserved holes are evenly distributed on the two brackets. The uniform setting can preferably avoid the occurrence of a quality difference between the two brackets, which affects the flight stability of the drone.

[0011] Further, the sponge block is specifically a sponge made of PU material, and several through holes are opened on the sponge block.

[0012] Further, a sliding sleeve is slidably sleeved on the bracket, and the sliding sleeve is a rubber sleeve. When water sample collection is not required, the sliding sleeve can be slid to the bottom of the bracket to cover the reserved holes.

[0013] The beneficial effects of the present utility model: The structure of the present utility model is simple and convenient to operate. The sampling structure can be quickly installed on the bracket, providing space for the drone to mount additional equipment. At the same time, after the drone moves the bracket to the target water area position, the sampling tube can be directly immersed in the water area, and the water sample can be sucked by means of the sponge block. Subsequently, the water sample sucked in the sponge block can be directly squeezed out to obtain the target water sample. By using the water sample collector of the present utility model, it is possible to sample the linear area of the water area and quickly complete the sampling within ten seconds.

[0020] Embodiment: Refer to Figure 1As shown, a water sample collector includes two brackets 1. Two crossbars 2 are installed between the two brackets 1, and a sampling structure 3 is provided on the bracket 1.

[0021] Next, the specific settings and functions of its sampling structure 3 will be described in detail.

[0022] Refer to Figures 2 to 5 As shown, the sampling structure 3 includes a number of reserved holes 37. A number of reserved holes 37 are opened on the bracket 1. A sampling tube 31 is threadedly connected in the reserved hole 37. When the sampling tube 31 is tightened by means of the thread, the lowermost end of the sampling tube 31 is flush with the lowermost end of the bracket 1. A partition 32 is fixedly connected inside the sampling tube 31. A number of leakage holes 38 are evenly opened on the surface of the partition 32. A sponge block 33 is arranged inside the sampling tube 31. The sponge block 33 is located on the partition 32. The sampling tube 31 can be directly and quickly installed on the bracket 1 of the unmanned aerial vehicle. The bracket 1 is the landing gear of the unmanned aerial vehicle. The bracket 1 is moved to the target water area by the flight of the unmanned aerial vehicle. By submerging the position where the sampling tube 31 is installed at the bottom of the bracket 1 into the water area, the water sample is sucked by means of the sponge block 33. In this solution, additional monitoring equipment can be mounted on the unmanned aerial vehicle to perform tasks. The upper end of the sampling tube 31 is threadedly connected with a round cover 34. The lower end of the round cover 34 abuts against the sponge block 33. The round cover 34 is of a hollow structure. The position of the sponge block 33 can be restricted without affecting normal sampling. A positioning plate 35 is fixedly connected to the arc surface of the sampling tube 31. When the sampling tube 31 is tightened on the bracket 1, the positioning plate 35 just contacts the bracket 1, which is convenient for positioning between the sampling tube 31 and the bracket 1. The number of reserved holes 37 is equally divided into two groups, and a number of reserved holes 37 are evenly distributed on the two brackets 1. The uniform setting can effectively avoid the generation of mass difference between the two brackets 1, which is beneficial to the flight stability of the unmanned aerial vehicle. The sponge block 33 is specifically a sponge made of PU material, and a number of through holes are opened on the sponge block 33. A sliding sleeve 36 is slidably sleeved on the bracket 1. The sliding sleeve 36 is a rubber sleeve. When water sample collection is not required, the sliding sleeve 36 can be slid to the bottom of the bracket 1 to cover the reserved hole 37.

[0023] In use, first install the crossbar 2 of the bracket 1 under the drone. When it is necessary to use the drone to perform a water sample collection task, directly place the sponge block 33 into the sampling tube 31, then tighten the round cover 34 on the sampling tube 31, and then screw the sampling tube 31 onto the reserved hole 37 of the bracket 1 by means of threads, so as to install the sampling structure 3 on the bracket 1. Then use the drone to carry the bracket 1 together with the sampling structure 3 to fly to the target water area, and then remotely control the drone to immerse the sampling tube 31 into the target water area. At this time, water will enter through the leakage holes 38 of the partition plate 32 and come into contact with the sponge block 33. At the same time, part of the water will also enter the sampling tube 31 from the hollow position of the round cover 34. At this time, the sponge block 33 will suck in water. After sucking in water, remotely control the drone to return, and then remove the sampling tube 31 from the bracket 1, so as to achieve the purpose of quickly performing water sample collection without occupying the drone mounting position. When it is not necessary to perform water sample collection, the sliding sleeve 36 on the bracket 1 can be slid to the lower part of the bracket 1 to cover and protect the reserved hole 37 on the bracket 1.

[0024] The water sample collector in the embodiment has a simple structure and is convenient to operate. The sampling structure can be quickly installed on the bracket, providing space for the drone to mount additional equipment. At the same time, after the drone moves the bracket to the target water area position, the sampling tube can be directly immersed in the water area, and the water sample is sucked by means of the sponge block. Subsequently, the water sample sucked in the sponge block is directly squeezed out to obtain the target water sample. By using this water sample collector, it is possible to sample the linear area of the water area, because the cross tube of the bracket is a linear structure and can complete sampling quickly within ten seconds.
