Technical Field

[0001] The utility model relates to a waste liquid collecting device for environmental detection, belonging to the technical field of waste liquid sampling and collection. Background Art

[0002] With the continuous development of social economy, the waste liquid and wastewater generated in industrial production are also increasing. In order to protect the ecological environment and the sustainable development of social economy, it is necessary to detect the discharged industrial waste liquid. Factories generally discharge waste liquid and wastewater through sewage pipes.

[0003] For the online sampling technology of sewage pipes, the previous process methods were only manual sampling or leading a bypass on the sewage main pipe and setting up a sampling device on the bypass.

[0004] At present, multiple samples are required for the detection of waste liquid. However, the existing online sampling equipment for sewage pipes is not convenient for interval sampling and cannot automatically collect multiple waste liquid samples as needed. In addition, the waste liquid remaining in the bypass during the sampling process will interfere with the accuracy of the next sampling sample.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a waste liquid collection device for environmental detection, which can perform interval sampling, facilitate automatic collection of multiple waste liquid samples as needed, and ensure the accuracy of each sampling sample.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A waste liquid collection device for environmental testing includes a sampling tube, the top of which is located in a sewage pipe, a turntable is provided below the bottom of the sampling tube, a plurality of sample bottles distributed in a circle are placed inside the turntable, the turntable is connected to a drive box at the bottom through a hollow shaft, and the hollow shaft penetrates the drive box in a vertical direction; the bottom of the drive box is slidably connected to a horizontally fixed linear slide rail through a slider; a guide groove is fixedly installed at the middle position of the top of the turntable, and the bottom of the guide groove is connected to the top of the hollow shaft.

[0009] Furthermore, the sampling tube is fixedly arranged in the fixed tube along the vertical direction.

[0010] Furthermore, the fixed pipe is fixedly connected to the bottom pipe wall of the sewage pipe.

[0011] Furthermore, a trumpet-shaped liquid inlet is provided at the top of the sampling tube, and the axis of the liquid inlet is arranged colinearly with the axis of the sewage pipe.

[0012] Furthermore, a solenoid valve for controlling water flow is installed at the bottom of the sampling tube.

[0013] Furthermore, the guide groove is located in the inner circle of multiple sample bottles.

[0014] Furthermore, a bearing seat is installed at the bottom and top of the inner cavity of the drive box, and the bearing seat is sleeved on the main body of the hollow shaft to support its rotation.

[0015] Furthermore, a transmission wheel is installed on the hollow rotating shaft, the transmission wheel is located between two bearing seats arranged upper and lower, and the transmission wheel is connected to the driving motor.

[0016] Furthermore, the side of the driving box is connected to the head of the electric telescopic rod, and the electric telescopic rod is fixedly arranged.

[0017] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0018] By setting up the diversion trough, the residual liquid can be drained before sampling to ensure the accuracy of each sample;

[0019] By setting an electric telescopic rod, the positions of the guide groove and the sample bottle can be flexibly switched. When the sampling tube faces the guide groove, the residual waste liquid can be drained, and when the sampling tube faces the sample bottle, sampling can be performed.

[0020] The driving motor in the utility model drives the turntable and the sample bottle to rotate step by step through the hollow rotating shaft, thereby realizing automatic collection and storage of multiple samples.
