Environmental monitoring is to monitor and measure the indicators reflecting the environmental quality to determine the pollution status of the environment and the level of environmental quality. A waste water sampling device is needed during the environmental monitoring process.

[0003] For the existing waste water sampling devices, most of them sink the sampling bottle tied with a rope into the water to complete the sampling and collection of waste water. However, this method is likely to cause larger impurities to enter the sampling bottle, thus affecting the sampling results. At the same time, after the existing waste water sampling devices are used, the inside of the sampling bottle cannot be quickly cleaned, and the impurities attached to the inner wall of the sampling bottle are likely to affect the water quality of the next sampling. Therefore, a waste water sampling device for environmental monitoring is proposed. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0020] The utility model provides a technical solution: AsFigures 1 to 4 As shown in the figure, in this embodiment, a waste water sampling device for environmental monitoring includes a sampling cylinder 1. A counterweight bin 2 is provided at the bottom of the sampling cylinder 1, and a counterweight mechanism is arranged inside the counterweight bin 2. A sealing cover 4 is provided at the upper end of the sampling cylinder 1. An inlet 7 is provided on the sealing cover 4, and a water isolation mechanism is arranged inside the inlet 7. A filter frame 9 is arranged on the inner side of the bottom of the sealing cover 4. A screen 10 is fixedly installed on the inner wall of the filter frame 9. A cleaning plate 11 is slidably installed inside the sampling cylinder 1, and a handle 12 is fixedly installed at the upper end of the cleaning plate 11.

[0021] Among them, the upper side of the outer wall of the sampling cylinder 1 is connected to the lower side of the outer wall of the sealing cover 4 by screw fit.

[0022] During use, the sealing cover 4 is rotatably installed at the upper end of the sampling cylinder 1. The top of the sampling cylinder 1 will press the filter frame 9 against the inner top wall of the sealing cover 4, thereby completing the fixation of the screen 10. At this time, the waste water entering the sampling cylinder 1 from the inlet 7 will be filtered by the screen 10 to prevent larger impurities from entering the inside of the sampling cylinder 1.

[0023] Among them, the counterweight mechanism is composed of a sealing bottom plate 13 and counterweight blocks 14. A plurality of counterweight blocks 14 are arranged inside the counterweight bin 2, and a sealing bottom plate 13 is arranged at the bottom of the counterweight bin 2. The sealing bottom plate 13 is connected to the counterweight bin 2 by screw fit.

[0024] During use, rotate the sealing bottom plate 13 to open the counterweight bin 2. At this time, by adding or reducing the number of counterweight blocks 14 in the counterweight bin 2, the overall weight of the sampling device can be adjusted.

[0025] Among them, the water isolation mechanism is composed of a motor 8 and a water isolation plate 16. A water isolation plate 16 is arranged inside the inlet 7. An activity slot 15 for accommodating the water isolation plate 16 is provided inside the sealing cover 4. The water isolation plate 16 is rotatably connected to the sealing cover 4. A motor 8 is fixedly installed at the top of the sealing cover 4, and the output shaft of the motor 8 is fixedly connected to the water isolation plate 16.

[0026] During use, the forward and reverse rotation of the motor 8 can be controlled through a remote control switch. When the output shaft of the motor 8 rotates forward by 180 degrees, the water isolation plate 16 can be separated from the inlet 7. When the output shaft of the motor 8 rotates backward by 180 degrees, the water isolation plate 16 can block the inlet 7 again.

[0027] Among them, a connecting arm 5 is arranged above the sealing cover 4. The two ends of the connecting arm 5 are respectively rotatably connected to the outer wall of the sealing cover 4. A clamping groove 6 is provided at the center position of the bottom of the connecting arm 5.

[0028] Among them, the sum of the internal thread depth of the sealing cover 4 and the thickness of the filter frame 9 is greater than the internal depth of the sealing cover 4.

[0029] With such a setting, it can be ensured that after the sampling cylinder 1 is threadedly connected to the sealing cover 4, the top of the sampling cylinder 1 can press against the filter frame 9.

[0030] Wherein, two reinforcing rings 3 are sleeved on the outer wall of the sampling cylinder 1, and the reinforcing rings 3 are fixedly connected to the sampling cylinder 1.

[0031] By providing the reinforcing rings 3, the structural strength of the sampling cylinder 1 can be improved, and the sampling cylinder 1 can be prevented from deforming.

[0032] The utility model provides a waste water sampling device for environmental monitoring, and the specific working principle is as follows:

[0033] During use, rotate the sealing bottom plate 13 to open the counterweight bin 2. At this time, add or reduce the number of counterweight blocks 14 in the counterweight bin 2 to adjust the overall weight of the sampling device, which is convenient for adjusting the sinking speed of the sampling cylinder 1. Tie the rope of the suspension device to the card slot 6 of the connecting arm 5, and then sink the sampling device into the water. When the rope sinks to an appropriate length, the forward and reverse rotation of the motor 8 can be controlled through the remote control switch. Control the output shaft of the motor 8 to rotate forward by 180 degrees, and the water isolation plate 16 can be separated from the water inlet 7. At this time, the water at this depth will enter the sampling cylinder 1 through the water inlet 7. The screen 10 inside the sealing cover 4 can filter the water to prevent larger impurities from entering the inside of the sampling cylinder 1. After the sampling is completed, control the output shaft of the motor 8 to rotate reversely by 180 degrees, and the water isolation plate 16 can block the water inlet 7 again.

[0034] Then, lift the sampling device out of the water through the suspension device, rotate the sealing cover 4, and remove the sealing cover 4. At this time, the screen 10 will also fall off naturally. The staff can take out the water sample in the sampling cylinder 1. At the same time, due to the natural fall of the screen 10, the staff can quickly clean the screen 10 to prevent the screen 10 from being blocked and affecting the next sampling. After the water in the sampling cylinder 1 is taken out, the staff can put their hand into the sampling cylinder 1 and hold the handle 12, and move the handle 12 up and down to drive the cleaning plate 11 to clean the inner wall of the sampling cylinder 1, preventing more impurities from adhering to the inner wall of the sampling cylinder 1 and affecting the subsequent water sampling. The bottom of the inner cavity of the sampling cylinder 1 will not contact the water due to the presence of the cleaning plate 11, which will not interfere with the water sample, and the cleaning plate 11 itself can be directly taken out for cleaning.

[0035] After cleaning, put the cleaning plate 11 back into the sampling cylinder 1, and put the filter frame 9 into the inner bottom of the sealing cover 4. When the sampling cylinder 1 and the sealing cover 4 are threadedly connected, the top of the sampling cylinder 1 will press the filter frame 9 against the inner top wall of the sealing cover 4, thus completing the fixation of the screen 10.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
