Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, and in particular to a wastewater detection and sampling device. Background Technology

[0002] When sampling and testing wastewater, it is usually necessary to collect wastewater samples from different depths and conduct multiple tests to obtain relatively accurate data. Wastewater sampling is usually carried out outdoors, which makes it inconvenient to store the samples and sampling instruments.

[0003] The technical solution disclosed in Chinese Patent No. CN220794730U adds a connecting hose between the sampling bottle and the sampling head, and fixes the hose to the sampling bottle and the sampling head respectively through a fixing component, so that the sampling head can be more flexibly put into the water. Furthermore, by setting scale lines on the connecting hose, the water depth of the sampling device can be more accurately determined, thereby improving the reliability of the test results.

[0004] However, the device still has shortcomings: it cannot automatically switch sampling bottles, and the sample transfer operation is troublesome when sampling sewage at different depths. In addition, when the device first extracts a sample, a large amount of air remains in the connecting hose, resulting in less water sample entering the sampling bottle. Furthermore, the structure is prone to causing the water sampled in the second sampling to mix with the water sampled in the first sampling in the connecting hose, making it difficult to obtain accurate data.

[0020] Example 1 like Figures 1-4As shown, this utility model proposes a wastewater testing and sampling device, including a remote-controlled boat 1, a rotating shaft 5, a drive assembly A8, a winding mechanism, a water pump 18, and an electric three-way regulating valve 20. A protective cover 3 is installed on the remote-controlled boat 1, and a bracket A4 and a bracket B11 are installed on the protective cover 3. The remote-controlled boat 1 includes a float, a steering baffle plate located at the bottom of the float, a power motor driving the steering baffle plate to rotate, and a turbine driving the float to move forward or backward. Support feet are provided at the bottom of the float. The rotating shaft 5 is rotatably connected to the bracket A4. A disc 6 is coaxially mounted on the rotating shaft 5, and several placement holes are arranged in a circular array around its axis on the disc 6. A test tube 7 is movably placed in each placement hole. The drive assembly A8 includes, but is not limited to, a motor A and a coupling A. The body of the motor A is mounted on the bracket A4, and the output end of the motor A is connected to the rotating shaft 5 through the coupling A. When in operation, the motor A drives the rotating shaft 5 to rotate around its axis. The winding mechanism is mounted on the support B11, and a connecting pipe 15 is mounted on the winding mechanism. One end of the connecting pipe 15 is inserted below the liquid surface. The winding mechanism includes a winding roller 12 and a drive assembly C13. The winding roller 12 is rotatably connected to the support B11. A guide hole 121 coaxial with the roller shaft of the winding roller 12 is provided. A through hole B122 communicating with the guide hole 121 is provided on the arc surface of the winding roller 12. A connecting pipe 15 is wound around the winding roller 12. The output end of the connecting pipe 15 is inserted into the through hole B122 and communicates with the guide hole 121. A rotary joint 14 coaxially rotates on the winding roller 12. The drive assembly C13 includes, but is not limited to, a drive shaft, pulley A, pulley B, a synchronous belt, a motor B, and a coupling B. The drive shaft is rotatably mounted on the support B11. Pulley A is coaxially connected to the drive shaft. Pulley B is coaxially connected to the roller shaft of the winding roller 12. Pulley A and pulley B are connected by a synchronous belt. The motor B is mounted on the support B11. The output end of the motor B is connected to the drive shaft through the coupling B. A ball net 16 is installed at the input end of the connecting pipe 15, and a counterweight 17 is installed at the bottom of the ball net 16. A through hole A101 is provided on the float plate, and a guide wheel 2 is installed in the through hole A101 to limit the sliding path of the connecting pipe 15. A water pump 18 is installed on the bracket B11, and a water pump pipe 19 is provided at the input end of the water pump 18. The input end of the water pump pipe 19 is connected to the guide hole 121 through a rotary joint 14. The input end of the electric three-way regulating valve 20 is connected to the output end of the water pump 18. The two output ends of the electric three-way regulating valve 20 are respectively provided with water outlet pipes A21 and B22, so as to discharge the ineffective water in the connecting pipe 15 through the water outlet pipe B22 and introduce the effective water into the corresponding test tube 7.

[0021] It should be noted that this embodiment also includes a remote controller, and the remote-controlled boat is equipped with a wireless signal transceiver and a PLC controller. The remote controller is connected to the remote-controlled boat via wireless signal communication.

[0022] In this embodiment, the remote-controlled boat 1 is placed on the water surface and controlled to move to an appropriate position. Then, motor B is started, which drives the take-up roller 12 to rotate, thereby slowly releasing the connecting pipe 15. The input end of the connecting pipe 15 gradually sinks below the water surface under the gravity of the counterweight 17. When the ball net 16 descends to the first detection height (this height is achieved by remotely stopping motor B), the water pump 18 is started, and the electric three-way regulating valve 20 is activated to connect the output end of the water pump 18 to the outlet pipe B22, initiating the pre-sampling drainage operation. After drainage is completed, the output end of the water pump 18 is connected to the outlet pipe A21, and the water in the outlet pipe A21 begins to enter the first detection point. After the first test tube 7 is filled with water, the electric three-way regulating valve 20 connects the output end of the water pump 18 to the outlet pipe B22 again to perform secondary drainage. At the same time, while maintaining the drainage state, the ball net 16 is adjusted to reach the second depth. The motor A drives the disc 6 to rotate at an appropriate angle (taking 10 test tubes 7 as an example, the motor A is a servo motor, and the motor A drives the disc 6 to rotate 36 degrees each time), rotating the second test tube 7 to below the outlet of the outlet pipe A21. After the secondary drainage is completed, the output end of the water pump 18 is connected to the outlet pipe A21 to fill the second test tube 7 with water. After all test tubes 7 are filled with water, the connecting pipe 15 is retracted and reset, and the remote control boat can be retrieved.

[0023] Example 2 like Figure 2 As shown, the wastewater testing and sampling device proposed in this utility model, compared with Embodiment 1, has a disc 6 slidably connected to a rotating shaft 5. A driving component B9 is provided on the rotating shaft 5 to drive the disc 6 to slide along the axial direction of the rotating shaft 5. The driving component B9 includes, but is not limited to, an electric telescopic rod. A sliding groove is provided on the rotating shaft 5, and a slider is provided in the sliding groove. The slider is connected to the disc 6. The body of the electric telescopic rod is provided in the sliding groove, and the output end of the electric telescopic rod is connected to the slider 6. A sealing plate 10 is provided at the bottom of the bracket A4 to seal the opening of each test tube 7 through the sealing plate 10.

[0024] In this embodiment, since the remote-controlled boat is easily affected by waves and sways when moving on the water, after sampling, in order to prevent the sample in the test tube 7 from spilling out, the electric telescopic rod can be remotely activated. The electric telescopic rod drives the disc 6 to rise to the sealing plate 10 to seal the opening of the test tube 7. In this state, no matter how the remote-controlled boat sways, the sewage sample will not spill out.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
