[0032] In one or more embodiments, the water injection hole can be arranged on the top of the sample storage box or other parts. When arranged on the top, the water injection hole can also serve as a sample outlet hole. When the water sample needs to be taken out, the sample storage box can be detached and inverted to take out the water sample. When arranged on other parts, a sample outlet hole can be additionally arranged, and a valve or other control switch can be arranged.

[0033] In one or more embodiments, the material of the sample storage box is plastic that can be deformed, has a relatively light weight, is convenient to carry, and can be squeezed to accelerate the speed of sample outlet when the sample is taken out.

[0034] In one or more embodiments, the sample storage box and the water storage box each comprise a tank body and a cover body. The cover body is arranged to facilitate cleaning of the sample storage box and the water storage box.

[0035] In one or more embodiments, the handheld sampler comprises a water suction pipe and a handheld part. The handheld part is arranged on one end of the water suction pipe, and the water suction pipe is connected with the sample inlet or the water outlet through a rubber tube. A switch is arranged on the handheld part, and the switch is used to control the switch of the first water pump and the second water pump. Anti-slip protrusions are arranged on the handheld part to increase the friction when the handheld part is gripped.

[0036] In one or more embodiments, the suction tube is a telescopic suction tube made of metal.

[0041] In one or more embodiments, a power supply is provided in the second housing for powering the two pump bodies. Figure 2 This is for illustrative purposes only and does not show the power supply or other structures housed within the second enclosure.

[0042] In one or more embodiments, the second housing is provided with a main switch, an indicator light, and a charging interface; the main switch is used to control the power supply, the indicator light is used to display the power supply, the first pump body, and the second pump body, and the charging interface is used to charge the battery.

[0043] In one or more embodiments, a solar panel is provided on the outside of the first housing. The solar panel is electrically connected to the battery to provide power and facilitate outdoor charging.

[0044] One embodiment of this utility model:

[0045] See Figures 1-4A backpack-style water sample collection device includes a first box 1 and a second box 2 arranged sequentially from top to bottom, and a handheld sampler 3;

[0046] The first box 1 is detachably equipped with nine sample storage boxes 11 and one water storage box 12; the sample storage boxes 11 and the water storage box 12 are the same size and are arranged in two rows of five in the first box 1; the top of the sample storage box 11 is provided with a water injection hole 111.

[0047] The second housing 2 contains a first pump body, a second pump body, a power supply, and a control panel; the second housing 2 has a sample inlet 21 and a water outlet 22; one end of the first pump body is connected to the sample inlet 21, and the other end is connected to any sample storage tank 11 via a flexible hose; the second housing 2 has a connection hole 23, through which the flexible hose connects the first pump body and the sample storage tank 11; one end of the second pump body is connected to the water outlet 22, and the other end is connected to the water storage tank 12;

[0048] The handheld sampler 3 is connected to the inlet 21 or the outlet 22;

[0049] The handheld sampler 2 includes a retractable metal suction tube 32 and a handheld part 31; the handheld part 31 is located at one end of the suction tube 32, and the suction tube 32 is connected to the sample inlet 21 or the water outlet 22 through a rubber tube 36; the handheld part 31 is equipped with a switch 33, which is connected to the control panel through two wires 35, and the handheld part 31 is equipped with anti-slip protrusions 34;

[0050] The top of the first box 1 is open, and the bottom of the first box 1 is provided with a positioning protrusion 13. The bottom of the sample storage box 11 and the water storage box 12 are both provided with positioning grooves that match the positioning protrusion 13. The positioning protrusion 13 and the first box 1 are preferably integrally formed.

[0051] The outer side wall of the first box 1 is provided with a shoulder strap 14; the outer side wall opposite to the outer side wall of the first box 1 where the shoulder strap 14 is provided is an openable and closable door structure.

[0052] The second housing 2 is equipped with a main switch 24, an indicator light 25, and a charging interface 26. The main switch 24 and the indicator light 25 are connected to the control panel via wires; the charging interface 26 is connected to the battery via wires.

[0053] A solar panel is provided on the outside of the first housing 1, and the solar panel is electrically connected to the battery.

[0054] The working principle of this embodiment is as follows: pure water is first poured into the water storage tank before sampling begins;

[0055] During sampling, a flexible hose is used to connect the first pump body to the water inlet of the first sample storage tank, and a rubber tube is connected to the sample inlet. The operator holds the handpiece, adjusts the length of the suction tube, and then inserts it into the water body to be sampled. The first pump body is turned on, and the water sample enters the first sample storage tank sequentially through the suction tube, the sample inlet, the first pump body, and the flexible hose. When the amount of water sample collected is sufficient, the first pump body is turned off; the flexible hose is pulled out, and the water inlet of the first sample storage tank is sealed.

[0056] Pull out the hose and connect it to the outlet. Turn on the second pump. The second pump will draw pure water from the storage tank to clean the hose and suction pipe.

[0057] Connect the tubing to the sample inlet, adjust the length of the suction tube, and then insert it into the water body to be sampled. Without connecting the tubing, turn on the first pump to allow the water sample to flow out of the tubing. Rinse the tubing with the water sample to avoid diluting the sample with pure water. Then turn off the first pump and connect the tubing to the water inlet of the second sample storage tank. Turn on the first pump again to allow the water sample to enter the second sample storage tank. After sampling is complete, turn off the first pump, remove the tubing, and seal the water inlet of the second sample storage tank.

[0058] Repeat the above steps as needed for the required number of water samples.

[0059] In summary, the backpack-type water sampling device provided by this utility model has the following advantages:

[0060] 1) Convenient for outdoor use, eliminating the need to carry multiple sampling and storage tools by hand, making it easy to carry and effectively freeing up your hands;

[0061] 2) By adjusting the suction tube of the handheld sampler, water samples at different depths can be collected, effectively improving the accuracy of sampling;

[0062] 3) By adjusting the suction tube of the handheld sampler, sampling can be carried out at some sampling points far from the shore, and the operator can do so while standing on the shore. This is suitable for scenarios where it is impossible to find a small sampling boat, and it also effectively improves the sampling efficiency.

[0063] 4) It can clean and rinse the sampling device, avoiding the problem of mutual interference when using the same device to collect different water samples due to outdoor conditions.

[0064] 5) Simple operation: sampling can be achieved simply by plugging and unplugging the pipe and controlling the switch. This avoids the cumbersome operations of frequent sampling, filling, and labeling required by traditional samplers, and avoids problems such as water spillage and insufficient collection that are common with traditional sampling devices, which require re-collection. This effectively improves the efficiency of sampling.
