Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown, the embodiment of the present invention provides a water body sampling and detection system, including a pretreatment end and a detection end. The pretreatment end includes a pumping station pipeline lifting system and a filtering device, and the detection end includes a water body sampling and detection robot. A detection device 17 is arranged on the robot to realize detection after water body sampling.

[0027] As Figure 1 and Figure 2 shown, the pretreatment end includes a frame 9, and both the pumping station pipeline lifting system and the filtering device are installed on the frame 9.

[0028] Specifically, the pumping station pipeline lifting system includes a water inlet pipe 1, a water inlet valve 2, a first centrifugal pump 3, a sample retention cup 6, a diaphragm pump 7, a water outlet 8, a second centrifugal pump 10, a water outlet valve 11 and a water outlet pipe 12. The filtering device includes a sampling box 4 and a filtering structure 5;

[0029] As Figure 2 shown, the sampling box 4 is respectively connected to the water inlet pipe 1 and the water outlet pipe 12. In addition, a water inlet valve 2 and a first centrifugal pump 3 are successively arranged on the water inlet pipe 1, a second centrifugal pump 10 and a water outlet valve 11 are successively arranged on the water outlet pipe 12. The filtering structure 5 is placed in the sampling box 4, the filtering structure 5 is connected to the sample retention cup 6 through the diaphragm pump 7, and the sample retention cup 6 is connected to the water outlet 8.

[0030] In order to prevent liquid overflow, protect the safety of the equipment, achieve quantitative sampling and improve the detection accuracy, an overflow port is provided on the sample retention cup 6.

[0031] The above is the pretreatment end, which is used for water body pretreatment and sample retention. Its specific process includes:

[0032] Open the water inlet valve 2, and the first centrifugal pump 3 sucks the real-time water sample from the sewage tank 19 through the water inlet pipe 1 into the sampling box 4;

[0033] The filtering structure 5 completes the filtration of the water body test sample (solid and colloidal substances);

[0034] The diaphragm pump 7 pumps the filtered water sample into the sampling cup 6;

[0035] The second centrifugal pump 10 pumps the remaining water sample in the sampling box 4 back to the sewage tank 19 and closes the water outlet valve 11.

[0036] As Figure 3 shown, the water body sampling and detection robot includes a mobile chassis 16 to realize the transfer of the robot to multiple sampling locations. It also includes a detection device 17 and an electric control cabinet 15. The detection device 17 and the electric control cabinet 15 are both fixedly connected to the mobile chassis 16, and the detection device 17 is signal-connected to the electric control cabinet 15; in this embodiment, the electric control cabinet 15 serves as a control device, and a PLC control cabinet or a single-chip microcomputer can also be used instead to realize the instruction transmission to the robot and the detection device 17.

One end of the robotic arm 14 is fixedly connected to the mobile chassis 16, and a water receiving funnel 13 is installed at the other end. The robotic arm 14 is signal-connected to the electric control cabinet 15. One end of the water inlet pipe 18 is connected to the water receiving funnel 13, and the other end is connected to the detection device 17.

[0038] The above is the detection end for water sample detection, and the water body sampling and detection robot executes the sampling and detection instructions;

[0039] After the electric control cabinet 15 sends the sampling and detection instructions, it controls the movement of the robotic arm 14 until the water receiving funnel 13 is placed in a suitable position, so that the water sample in the sampling cup 6 flows into the water receiving funnel 13 through the water outlet 8, and then flows into the detection device 17 through the water inlet pipe 18 for inspection. It should be noted that the process of sending action instructions and detection instructions through the electric control cabinet 15 is based on and adopts the control algorithms in the existing technology.

[0040] After the detection device 17 completes the water sample detection, the electric control cabinet 15 uploads the detection data to the console or the background, which is convenient for the staff to directly understand the current water sample detection situation. It should be noted that the above detection data transmission uses existing communication technologies, such as AP networking or 4G / 5G, etc.

[0041] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model.
