[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] Refer to Figures 1-7 , the present utility model provides a portable runoff sampling device, including:

[0031] Main box body 1, a shoulder strap 4 is arranged on the main box body 1, the bottom of the main box body 1 is detachably connected with a sample box body 6, several sampling bottles 13 are placed in the sample box body 6, a water pumping assembly is arranged in the main box body 1, the water outlet end of the water pumping assembly is communicated with several water filling branch pipes 18, and several sampling bottles 13 are respectively arranged corresponding to the several water filling branch pipes 18;

[0032] Drainage through pipe 3, the drainage through pipe 3 is detachably connected to the main box body 1, two ends of the drainage through pipe 3 are respectively set as a water inlet and a water outlet, a water inlet hard pipe 9 is arranged in the drainage through pipe 3, one end of the water inlet hard pipe 9 is arranged close to the water outlet of the drainage through pipe 3, and the other end of the water inlet hard pipe 9 is communicated with the water pumping assembly;

[0033] Body-hugging box body 2, the body-hugging box body 2 is fixedly connected to a vertical side wall of the main box body 1.

[0034] The main function of the shoulder strap 4 is to facilitate the operator to carry the sampling device; the main function of the body-hugging box body 2 is to improve the comfort during carrying; the main function of the sample box body 6 is to facilitate the quick placement of several sampling bottles 13 to the position of receiving water samples. At the same time, since the sample box body 6 can be taken off from the main box body 1, it is convenient for the taking and placing of the sampling bottles 13; the main function of the water pumping assembly is to pump the water in the runoff into the sampling bottles 13; the main function of the water filling branch pipes 18 is to directly pour the sampled water into the corresponding sampling bottles 13; the main function of the drainage through pipe 3 is to be placed into the runoff along the water flow direction, so that part of the water flows through the drainage through pipe 3, which can not only facilitate the water inlet hard pipe 9 to draw water samples, but also reduce the disturbance to the runoff during the water taking process. Overall, the present utility model is convenient to carry, comfortable to carry, can realize multi-point sampling, and is suitable for the sampling requirements of field, especially surface runoff on mountain slopes; at the same time, during the sampling process, since part of the water flows through the drainage through pipe and the water in the drainage through pipe is sampled, the interference to the runoff can be reduced, and the sampled water samples can be more in line with the actual situation.

[0035] In a further optimized scheme, a processor 19 is arranged in the main box body 1, and a control panel 25 is arranged on the top of the main box body 1. The operator issues an instruction to the processor 19 through the control panel 25, and the processor 19 controls the water pumping assembly to work according to the instruction.

[0036] In a further optimized scheme, as Figure 6 shown, several water bottle slots 12 are opened on the sample box body 6. The water bottle slots 12 are used for placing the sampling bottles 13.

[0037] For a further optimized solution, the water inlet hard pipe 9 vertically slides through the top of the drainage pipe 3. The bottom of the water inlet hard pipe 9 is horizontally connected to a water inlet pipe 21. The water inlet pipe 21 is located inside the drainage pipe 3, and the water inlet of the water inlet pipe 21 faces the water inlet direction of the drainage pipe 3. A friction sleeve 10 is slidably sleeved on the water inlet hard pipe 9. The friction sleeve 10 is located outside the drainage pipe 3, and the friction sleeve 10 is in contact with the top of the drainage pipe 3.

[0038] As Figure 4 and Figure 5 shown, there is a large frictional force between the friction sleeve 10 and the water inlet hard pipe 9. Due to this frictional force, the friction sleeve 10 can prevent the water inlet hard pipe 9 from falling vertically due to gravity. When it is necessary to increase the height of the water inlet pipe 21 inside the drainage pipe 3, the operator first lifts the water inlet hard pipe 9 upward. Then, the friction sleeve 10 is moved downward along the water inlet hard pipe 9 to make the friction sleeve 10 closer to the water inlet pipe 21. After moving to the appropriate position, the water inlet hard pipe 9 is lowered. When the friction sleeve 10 is in contact with the top of the drainage pipe 3, the water inlet hard pipe 9 stops descending. At this time, due to the downward movement of the friction sleeve 10 relative to the water inlet hard pipe 9, the position of the water inlet pipe 21 will be raised. Similarly, when it is necessary to lower the height of the water inlet pipe 21, the friction sleeve 10 is moved away from the water inlet pipe 21.

[0039] After the drainage pipe 3 is placed at the bottom of the runoff, by adjusting the height of the water inlet hard pipe 9, the purpose of collecting water samples at different depths can be achieved. The main function of the water inlet pipe 21 is to enable the flowing water and the mixture therein to directly collide into the water inlet hard pipe 9 during the flow process, so that the water sample flowing into the water inlet hard pipe 9 can be as close as possible to the water sample situation at this height.

[0040] For a further optimized solution, the water pumping assembly includes a water pump 14 arranged in the main box body 1. The water inlet connecting pipe 15 on the water pump 14 is connected to one end of the water inlet hard pipe 9 away from the drainage pipe 3 through a hose 5. The water outlet end of the water pump 14 is connected to a main water outlet pipe 16. A number of irrigation branch pipes 18 are respectively connected to the main water outlet pipe 16.

[0041] For a further optimized solution, electromagnetic valves 17 are respectively connected to the a number of irrigation branch pipes 18.

[0042] For a further optimized solution, the water pump 14 and a number of electromagnetic valves 17 are respectively electrically connected to the processor 19.

[0043] As Figure 3As shown in the figure, before sampling, each solenoid valve 17 is in a closed state. After the position of the water inlet pipe 21 is set, the operator uses the control panel 25 to make the processor 19 control the water pump 14 to operate. The water pump 14 sends the sampled water sample into the outlet main pipe 16 through the inlet hard pipe 9 and the hose 5. At the same time, the processor 19 controls a solenoid valve 17 to open for a specific time, and the water sample flows into the corresponding sampling bottle 13 through the irrigation branch pipe 18 connected to the solenoid valve 17. After the time is up, the solenoid valve 17 closes. If continuous sampling is required, the processor 19 controls another solenoid valve 17 to open and continues to collect the water sample.

[0044] For a further optimized solution, a plug 22 is fixedly connected to the inner side of the drainage pipe 3. A slot 8 is opened on one side of the main box body 1 away from the body-hugging box body 2, and the slot 8 is adapted to the plug 22.

[0045] As Figure 2 and Figure 5 shown in the figure, the slot 8 is opened downward from the top of the main box body 1, and the plug 22 on the drainage pipe 3 can be snapped into the slot 8 from the top downward, so as to realize the fixation between the drainage pipe 3 and the main box body 1 and facilitate carrying. When in use, only need to pull out the drainage pipe 3 upward.

[0046] For a further optimized solution, an ultrasonic flow monitor 20 is fixedly connected to the inner bottom of the drainage pipe 3.

[0047] As Figure 4 shown in the figure, by setting the ultrasonic flow monitor 20, the flow velocity or flow rate of the water flow can be monitored during the sampling process, and the monitoring data is transmitted to the processor 19, so that the flow rate and other conditions of the runoff can be measured during the sampling process.

[0048] For a further optimized solution, a battery 11 is arranged in the body-hugging box body 2.

[0049] As Figure 7 shown in the figure, the battery 11 can provide power for the operation of the water pump 14, the solenoid valve 17, the ultrasonic flow monitor 20, the processor 19, etc.

[0050] For a further optimized solution, a lifting rope 23 is arranged between two opposite edges at the top of the sample box body 6, and a placement groove 24 is opened at the top of the sample box body 6 for storing the lifting rope 23.

[0051] As Figure 6 shown in the figure, by arranging the lifting rope 23 on the sample box body 6, the portability of the sample box body 6 can be improved. During field sampling, the operator can carry multiple sample box bodies 6, and thus can carry more sampling bottles 13, and at the same time, the placement problem of a large number of sampling bottles 13 is also solved.

[0052] According to a further optimized solution, a stopper 7 is rotatably connected to the side wall of the main box 1 close to the sample box 6. The stopper 7 is used to prevent the sample box 6 from sliding outward after the sample box 6 is inserted into the main box 1, thereby fixing the sample box 6.

[0053] like Figure 1 and Figure 3 As shown, a groove is provided inwardly at the bottom of the main box 1, and the sample box 6 slides inwardly into the groove. After sliding into place, the stopper 7 rotates downward by gravity, so that the end of the stopper 7 away from the rotating shaft fits with the side wall of the sample box 6 away from the main box 1, thereby limiting the sample box 6.

[0054] The working process of this embodiment is as follows: the operator places the main box 1 on the ground next to the surface runoff collection point, removes the drainage pipe 3 from the main box 1, and adjusts the height of the water inlet hard pipe 9 by adjusting the position of the friction sleeve 10, so that the water inlet pipe 21 is at a predetermined height in the drainage pipe 3. Afterwards, the drainage pipe 3 is placed in the runoff in parallel along the direction of the water flow, and the drainage pipe 3 is in contact with the bottom of the runoff. Afterwards, the control panel 25 is operated to enable the processor 19 to control the water pump 14 and the solenoid valve 17 to work, and collect water samples from each sampling bottle 13 in turn. During the process, if the height of the water inlet pipe 21 needs to be adjusted, it is only necessary to adjust the height of the friction sleeve 10 on the water inlet hard pipe 9.

[0055] After all the sampling bottles 13 in a group of sample boxes 6 have collected samples, the next group of sample boxes 6 can be replaced to continue the sampling work.
