Description

Technical Field

[0001] The utility model relates to the technical field of water pollution detection, in particular to a groundwater pollution source analysis and tracing device. Background Art

[0002] The main causes of groundwater pollution are: direct discharge of industrial wastewater into the ground, intrusion of contaminated surface water into underground aquifers, infiltration of human and animal feces or water contaminated by excessive use of pesticides into the ground, etc.

[0003] A Chinese patent with announcement number CN218112931U discloses a river ecological pollution tracing device. It uses an unmanned boat to carry out online water ecological monitoring. Every time the unmanned boat travels a certain distance, it conducts sampling and analysis. By analyzing the concentration of water pollution sources in various directions, the direction of the pollution source is determined, and sampling and analysis are continuously carried out in the direction of the pollution source until the pollution source is found. This replaces the traditional manual sampling method by boat, greatly reduces safety hazards, and can automatically pump water, detect, and analyze the pollution concentration of the water ecology, greatly improving work efficiency.

[0004] Although the above solution uses a waste liquid recovery tank to centrally collect samples after detection by the detector, the waste liquid will be mixed after being collected in the recovery tank, and the obtained samples cannot be subsequently analyzed again. In addition, the method of sending sample water into the detector is prone to sample water residue, which affects the detection accuracy of the detector. To this end, we provide a groundwater pollution source analysis and tracing device to solve the above problems. Utility Model Content

Two propeller thrusters 3 are installed on the lower hull 1, and the propeller thrusters 3 can be used to move the inspection ship in the groundwater channel. A partition plate 6 is fixedly connected to the lower hull 1, and the space inside the lower hull 1 is divided into an equipment compartment and an inspection compartment by the partition plate 6.

[0030] Two turntables 19 are symmetrically arranged in the inspection chamber. Both turntables 19 are provided with through holes in a circular array. A storage tank 20 is placed in each through hole. A convex ring 21 is fixedly connected to the storage tank 20. Two through holes 22 are provided on the upper surface of the storage tank 20. The turntable 19 is circular. The convex ring 21 can ensure the stability of the storage tank 20 placed in the through hole, and the storage tank 20 can be pulled out of the through hole from the upper part of the storage tank 20.

[0031] There are two fixedly connected access windows 4 on the upper hull 2, and the access windows 4 are adapted to the turntable 19. Both access windows 4 are hinged with window doors 5. After the access windows 4 are opened through the window doors 5, the storage tank 20 can be easily taken out.

[0032] The rotating assembly is arranged in the equipment cabin and is used to rotate the turntable 19 to change the position of the storage tank 20. The rotating assembly includes a motor 17 installed on the partition plate 6. The output shaft of the motor 17 is equipped with a rotating rod 18, and the top of the rotating rod 18 is fixedly connected to the turntable 19. The rotating rod 18 is driven to rotate by the output shaft of the motor 17, so that the turntable 19 can rotate in the detection cabin, thereby adjusting the position of the storage tank 20.

[0033] Two electric push rods 11 are symmetrically installed on the upper hull 2. The telescopic ends of the two electric push rods 11 are fixedly connected to a connecting plate 12. The connecting plate 12 is installed with a detection head 10 and a drainage pipe 13. The drainage pipe 13 is fixedly connected with a water injection head 16. The electric push rods 11 drive the connecting plate 12 to move, so that the detection head 10 and the water injection head 16 pass through the through hole 22 and extend into the storage tank 20.

[0034] The telescopic end of the electric push rod 11 can drive the connecting plate 12 to move downward, so that the detection head 10 and the water injection head 16 can pass through the through-hole 22 and extend into the interior of the storage tank 20. The sample water is injected into the storage tank 20 through the water injection head 16, and the sample water is tested by the detection head 10. After the test is completed, the detection head 10 and the water injection head 16 can be pulled out from the current storage tank 20 through the electric push rod 11, and after the turntable 19 rotates a certain angle, the new storage tank 20 is moved to the bottom of the detection head 10 and the water injection head 16.
