Through sampling and analysis, water quality problems can be discovered in a timely manner, and corresponding treatment measures can be taken to protect water resources and the ecological environment.

[0003] When sampling sewage at different depths, the existing sewage sampling device for environmental testing needs to alternately disassemble and replace the liquid storage cylinder for sampling. This leads to frequent disassembly and assembly of the liquid storage cylinder during the sampling process, resulting in low sewage sampling efficiency and extremely inconvenient operation.

[0004] At present, there is still a lack of equipment that can facilitate sewage sampling in different depth areas and collect multiple samples at one time. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an efficient multi-point sewage sampling device and method, which is convenient for sewage sampling in different depth areas and can collect multiple samples at one time.

[0006] The present invention adopts the following technical solutions to achieve the invention objectives:

[0008] As a further limitation of the present technical solution, each of the piston columns at the rear end is respectively fixedly connected to a spring, and each of the springs is respectively fixedly connected to the cylinder.

[0009] As a further limitation of the present technical solution, the cylinder body is fixedly connected to the lower mounting seat, the lower mounting seat is fixedly connected to the power motor, the output shaft of the power motor is fixedly connected to the screw rod, the screw rod is threadedly connected to the threaded cylinder, the threaded cylinder passes through the lower mounting seat, the threaded cylinder is fixedly connected to the mounting vertical rod, and the mounting vertical rod is fixedly connected to the front cover.

[0010] As a further limitation of the present technical solution, the front end of the cylinder is fixedly connected to a symmetrical inward electric propeller, the middle part of the cylinder is fixedly connected to a symmetrical lifting electric propeller, and the rear end of the cylinder is fixedly connected to a symmetrical outward electric propeller.

[0011] As a further limitation of the technical solution, the sampling tube is installed with a one-way exhaust valve, so that when liquid enters the sampling tube, the gas in the sampling tube is discharged.

[0012] As a further limitation of the present technical solution, the cylinder is fixedly connected to the upper mounting plate, the upper mounting plate is fixedly connected to the mounting frame, the mounting frame is fixedly connected to the I-tube plate, the mounting frame is fixedly connected to the electric push rod, the push rod of the electric push rod passes through the I-tube plate, the push rod of the electric push rod is fixedly connected to the H-plate, the I-tube plate is rotatably connected to two groups of symmetrical swing arms, the H-plate is rotatably connected to symmetrical scissor blades, and each of the swing arms is rotatably connected to the corresponding scissor blade.

[0013] As a further limitation of the technical solution, the cylinder is fixedly connected to two groups of symmetrical supporting diagonal rods, each of the supporting diagonal rods is respectively fixedly connected to a cross rod, and the symmetrical cross rods are respectively fixedly connected to a longitudinal rod.

[0014] An efficient sampling method of a multi-point sewage sampling device comprises the following steps:

[0015] S1: operate the outward electric propeller, the lifting electric propeller and the inward electric propeller to make the cylinder dive to a preset position. In the initial state, the front cover contacts the end cover to prevent water from entering the cylinder;

[0016] S2: Control the power motor to rotate forward first, so that the power rod is away from the hemisphere, so that water enters the cylinder, and then control the power motor to rotate in the reverse direction, control the rotation motor to rotate, and each time the rotation motor rotates a certain degree, a sampling of the sampling tube is realized. When the power rod contacts the hemisphere, the piston column at the rear side is moved, so that the water inlet hole is moved out of the sampling tube, so that water enters the sampling tube;

[0021] In the initial state, the front cover contacts the end cover to prevent water from entering the cylinder, thereby preventing foreign matter from entering and preventing the sampled water sample from being contaminated when it rises to the water surface.

[0022] When the cylinder is at a suitable position and multi-point sampling is required, the rotating motor rotates a certain degree each time to sample one of the sampling tubes, and multiple positions are rotated separately to achieve multi-point sampling. After sampling, the rotating motor returns to the initial state and controls the power rod to be between the two hemispheres to facilitate the next sampling.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] 1. This device adopts a front cover and a partition net. The front cover contacts the end cover to prevent water from entering the cylinder, thereby preventing debris from entering and preventing the water sample after sampling from being contaminated when it rises to the water surface. The partition net can prevent debris from entering and protect the cylinder.

[0025] 2. When the cylinder of the device is in the appropriate position and multi-point sampling is required, the rotating motor rotates a certain degree each time to sample a sampling tube, and multiple positions are rotated to achieve multi-point sampling. After sampling, the rotating motor will return to the initial state, and the power rod will be controlled to be between the two hemispheres to facilitate the next sampling. When the power rod contacts the hemisphere, it drives the hemisphere to move, the rear piston column moves along the sampling tube, and the water inlet hole moves out of the sampling tube, allowing water to enter the sampling tube to achieve sampling. After the power rod is out of contact with the hemisphere, the spring recovers, and the piston column enters the sampling tube to achieve sample preservation. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] An efficient sampling method of a multi-point sewage sampling device comprises the following steps:

[0047] S1: operate the outward electric propeller 6, the lifting electric propeller 7 and the inward electric propeller 11 to make the cylinder 3 dive to a preset position. In the initial state, the front cover 1 contacts the end cover 25 to prevent water from entering the cylinder 3;

[0048] S2: Control the power motor 20 to rotate forward first, so that the power rod 21 is away from the hemispherical body 28, so that water enters the cylinder 3, and then control the power motor 20 to rotate in the reverse direction, and control the rotation motor 22 to rotate. Each time the rotation motor 22 rotates a certain degree, a sampling of the sampling tube 31 is realized. When the power rod 21 contacts the hemispherical body 28, the rear piston column 29 is moved, so that the water inlet hole 35 is moved out of the sampling tube 31, so that water enters the sampling tube 31;

[0053] In the initial state, the front cover 1 contacts the end cover 25 to prevent water from entering the cylinder 3, thereby preventing foreign matter from entering and preventing the sampled water sample from being contaminated when it rises to the water surface.

[0054] When the cylinder 3 is at a suitable position and multi-point sampling is required, the rotating motor 22 rotates a certain degree each time to sample one of the sampling tubes 31, and multiple positions are rotated separately to achieve multi-point sampling.

After sampling, the rotating motor 22 will return to the initial state, and the power rod 21 will be controlled to be between the two hemispheres 28, which is convenient for the next sampling. When the power rod 21 contacts the hemisphere 28, it drives the hemisphere 28 to move, and the rear piston column 29 moves along the sampling tube 31, and the water inlet hole 35 moves out of the sampling tube 31, so that water enters the sampling tube 31 to achieve sampling. After the power rod 21 is out of contact with the hemisphere 28, the spring 34 is restored, and the piston column 29 enters the sampling tube 31 to achieve sample preservation.
