[0003] Nowadays, through the sampling device, it is convenient to sample and preserve the water body when the water quality needs to be detected, which is convenient for detection. However, it is inconvenient to sample the deeper water quality during sampling, which may affect the overall detection of the water body to be detected. To solve the above problems, a sampling device for water quality detection that can sample at depths is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sampling device for water quality detection to solve the problem that it is inconvenient to sample the deeper water quality during sampling, which may affect the overall detection of the water body to be detected.

The bottom end of the hanging plate is rotatably connected to a fixed block. One side of the fixed block is provided with a water absorption component. The top of the water absorption component is provided with a rubber hose. The bottom of the water absorption component is provided with a storage tube. The bottom of the storage tube is provided with a disassembly component. The bottom of the disassembly component is provided with a weight.

[0006] As a further description of the above technical scheme:

[0007] The water absorption component includes a waterproof shell. Fixed plates are fixedly connected to the outer walls on both sides of the waterproof shell. An air inlet pipe is fixedly connected to the fixed plate on one side of the waterproof shell. A rubber hose is fixedly connected to the top surface of the waterproof shell.

[0008] As a further description of the above technical scheme:

[0009] An electric push rod is arranged inside the waterproof shell. A telescopic tube is fixedly connected to the bottom surface of the fixed plate. The bottom end of the telescopic tube is fixedly connected to a pressing disc. A rubber ring is fixedly connected to the side wall of the pressing disc.

[0010] As a further description of the above technical scheme:

[0011] The output shaft of the electric push rod is fixedly connected to a pressing disc. The output rod of the electric push rod is located inside the telescopic tube. A suction pipe is arranged in the weight.

[0012] As a further description of the above technical solution:

[0013] The disassembly component includes a threaded ring. A protrusion is provided at the bottom of the threaded ring. A sealing ring is fixedly connected to the protrusion at the bottom of the threaded ring. A storage tube is fixedly connected to the top surface of the threaded ring. The outer surface of the threaded ring is threadedly connected to a threaded circle.

[0014] As a further description of the above technical solution:

[0015] A mounting plate is fixedly connected to the bottom surface of the threaded circle. A weight is fixedly connected to the bottom surface of the mounting plate. Through holes are provided in both the mounting plate and the weight. Suction pipes are fixedly connected to the through holes in the mounting plate and the weight.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, by setting, during use, the circuit is connected to the electric push rod through a rubber hose to control the electric push rod. Then, the exhaust hose is fixedly connected to the intake pipe, and the rope is used to fix the round hole at the top of the hanging plate. After the connection, the sampling device is put into the water. The device sinks to a deeper water bottom through the weight. At this time, the electric push rod is started. The extrusion disc is driven by the electric push rod, and then the rubber ring is driven by the extrusion disc. The extrusion disc and the rubber ring are lifted upward by the output shaft of the electric push rod, and the gas inside the storage tube is discharged through the intake pipe and the exhaust hose, so that the water body is sucked into the storage tube through the suction pipe. After the suction, the sampling device is pulled out through the rope. When the electric push rod expands and contracts, the telescopic tube can be driven, and the telescopic tube protects the output shaft of the electric push rod. When it is necessary to take out the water body for detection, the water body in the storage tube is taken out by using the electric push rod and the extrusion disc. Through this design, it is convenient to use the electric push rod and the extrusion disc to sample the deeper water body when the sampling device sinks to a deeper water, and the output shaft of the electric push rod can be protected by the telescopic tube while the electric push rod expands and contracts.

[0018] 2. In the present utility model, by setting, after all the water inside the sampling device is taken out, some impurities may remain inside the storage tube. At this time, the threaded circle is rotated to disengage the threaded circle from the threaded ring, so that the mounting plate and the weight are removed, and the impurities inside the storage tube are cleaned to prevent affecting subsequent sampling. Through this design, it is convenient to remove the mounting plate and the weight by using the threaded circle and the threaded ring to clean the impurities inside the storage tube, and prevent some impurities from remaining inside the storage tube and affecting subsequent sampling detection.
