Detailed Embodiments

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0034] The utility model provides a reservoir water quality monitoring device, which can extract water quality at different depths, and has functions of real-time water quality detection and water sample storage at the same time. It has various functions and meets different usage requirements.

[0035] Please refer to Figures 1 to 5 , the utility model provides a reservoir water quality monitoring device, including a mounting frame 1, a mounting box 2, a floating airbag 4, a water inlet assembly 5, a rotating assembly 6, a first water pumping assembly 7A, a second water pumping assembly 7B, a detection assembly 8, a storage assembly 9 and a PLC controller 12;

[0036] A mounting box 2 is fixedly installed at the top of the mounting frame 1; the detection assembly 8 and the storage assembly 9 are respectively arranged on the left and right sides inside the mounting box 2; a floating airbag 4 is fixedly installed on the periphery of the mounting frame 1; the water inlet assembly 5 includes a rotating pipe 51 and a water inlet hose 52; the rotating pipe 51 is horizontally rotatably installed inside the mounting frame 1; the water inlet hose 52 is vertically arranged, and the top water outlet of the water inlet hose 52 is communicated with the side wall of the rotating pipe 51; the rotating assembly 6 can be located on the right side of the mounting frame 1 and is used to drive the rotating pipe 51 to rotate, so that the top of the water inlet hose 52 is wound around the outer periphery of the rotating pipe 51; one water outlet of the rotating pipe 51 is communicated with the water inlet of the detection assembly 8 through the first water pumping assembly 7A; the other water outlet of the rotating pipe 51 is communicated with the water storage port of the storage assembly 9 through the second water pumping assembly 7B; the first water pumping assembly 7A and the second water pumping assembly 7B are respectively located on the left and right sides of the mounting box 2.

[0037] The PLC controller 12 is respectively connected to the rotating assembly 6, the first water pumping assembly 7A, the second water pumping assembly 7B, the detection assembly 8 and the storage assembly 9.

[0038] The utility model provides a reservoir water quality monitoring device, and its usage method is as follows:

[0039] When in use, the mounting frame 1 is placed in the reservoir. After placement, the floating airbag 4 will ensure that the mounting frame 1 floats on the water surface of the reservoir; the rotating assembly 6 is used to drive the rotating pipe 51 to rotate, so as to adjust the number of turns of the top of the water inlet hose 52 wound around the outer periphery of the rotating pipe 51, realize the winding of the top of the water inlet hose 52, and then adjust the depth of the bottom water inlet of the water inlet hose 52, so as to extract the water quality at different depths.

[0040] When the depth adjustment of the water inlet at the bottom of the water inlet hose 52 is in place, the first pumping assembly 7A and the second pumping assembly 7B are started simultaneously. The first pumping assembly 7A transports the water extracted by the water inlet hose 52 to the detection assembly 8 for real-time water quality detection, and stores the detection results inside the detection assembly 8. The second pumping assembly 7B transports the water extracted by the water inlet hose 52 to the storage assembly 9 for sample storage. In the later stage, the samples stored in the storage assembly 9 are accurately detected by an external laboratory, and then the detection results are compared with the detection results stored in the detection assembly 8, so as to accurately know the water quality conditions at different depths, thereby effectively improving the accuracy of monitoring.

[0041] Based on the above structure, the following improvements can also be made:

[0042] The assembly method of the mounting frame 1 and the floating airbag 4 is as follows: It also includes a fixing ring 3; the mounting frame 1 and the floating airbag 4 are connected and fixed through the fixing ring 3. Specifically, the fixing ring 3 is fixed on the side of the mounting frame 1, and an annular groove is provided on the circumferential surface of the fixing ring 3, and the floating airbag 4 is fixed inside the annular groove. Through the floating airbag 4, the whole device floats on the water surface.

[0043] The water inlet assembly 5 is used to extract water at different depths and transport it to the rotating pipe 51. As a specific implementation structure, the water inlet assembly 5 further includes a filter screen barrel 53 and a guiding pipe 54; the bottom water inlet end of the water inlet hose 52 is installed with the filter screen barrel 53; the outer part of the top water outlet of the water inlet hose 52 is sleeved with the guiding pipe 54, and the guiding pipe 54 is fixed to the mounting frame 1. Therefore, the extracted water is first filtered by the filter screen barrel 53, and then flows through the water inlet hose 52 and into the rotating pipe 51.

[0044] The rotating assembly 6 is used to drive the rotating pipe 51 to rotate, thereby winding up the water inlet hose 52 and adjusting the depth of the bottom water inlet end of the water inlet hose 52 to achieve sampling of water at different depths. As a specific implementation structure, refer to Figure 3 , the rotating assembly 6 includes a motor 61, a gear 62 and a gear ring 63; the motor 61 is installed outside the mounting frame 1, the output shaft of the motor 61 is fixed with the gear 62, the gear ring 63 is fixed outside the rotating pipe 51, the gear ring 63 meshes with the gear 62, and the input end of the motor 61 is electrically connected to the output end of the PLC controller 12. The PLC controller 12 controls the start and stop of the motor 61, and drives the rotating pipe 51 to rotate through the motor 61.

[0045] The first pumping assembly 7A and the second pumping assembly 7B are used to extract and transport the water samples in the rotating pipe 51. As a specific implementation structure, the structures of the first pumping assembly 7A and the second pumping assembly 7B are the same, and both include a first water outlet pipe 71, a first water pump 72, a connecting pipe 73 and a tapered water outlet pipe 74;

[0046] One end of the first water outlet pipe 71 is rotatably connected to the water outlet of the rotating pipe 51; the other end of the first water outlet pipe 71 is communicated with the water inlet of the first water pump 72; the water outlet of the first water pump 72 is connected to one end of the connecting pipe 73; the other end of the connecting pipe 73 is fixedly installed with a conical water outlet pipe 74; the water outlet of the conical water outlet pipe 74 is located above the water inlet of the detection assembly 8 or the water storage port of the storage assembly 9; the input end of the first water pump 72 is electrically connected to the output end of the PLC controller 12.

[0047] The PLC controller 12 controls the first water pump 72 in the first water pumping assembly 7A and the second water pumping assembly 7B, and the first water pump 72 pumps the water in the rotating pipe 51 into the detection assembly 8 and the storage assembly 9 respectively. At the same time, since one end of the first water outlet pipe 71 is rotatably connected to the water outlet of the rotating pipe 51, the first water outlet pipe 71 does not restrict the rotation of the rotating pipe 51, ensuring that the rotating pipe 51 can rotate flexibly.

[0048] The detection assembly 8 is used to detect the water quality of the sampled water in real time. As a specific implementation structure, refer to Figure 4 , the detection assembly 8 includes a water quality detector 81, a second water pump 82, a drain pipe 83 and a second water outlet pipe 84;

[0049] The water inlet of the detection tank of the water quality detector 81 is located directly below the water outlet of the first water pumping assembly 7A; the second water pump 82 is fixedly installed outside the water quality detector 81, and the water inlet of the second water pump 82 is communicated with the drainage end of the drain pipe 83; the water inlet end of the drain pipe 83 is communicated with the detection tank of the water quality detector 81; the water outlet of the second water pump 82 is communicated with the water inlet of the second water outlet pipe 84; the water outlet of the second water outlet pipe 84 is communicated with the external environment;

[0050] The water quality detector 81 and the second water pump 82 are electrically connected to the PLC controller 12.

[0051] Therefore, the water sample pumped by the first water pumping assembly 7A is transported into the detection tank of the water quality detector 81, and the water quality detector 81 detects the water sample in the detection tank in real time, and the detection data will be saved inside the water quality detector 81. After the detection is completed, the second water pump 82 is started to pump the detected water out of the detection tank of the water quality detector 81 and discharged to the outside through the second water outlet pipe 84, which is convenient for detecting the water sampled at different positions next time.

[0052] The storage assembly 9 is used to store the water sampled at different depths. As a specific implementation structure, refer to Figure 5 , the storage assembly 9 includes a servo motor 91, a storage disk 92 and a storage pipe 93;

[0053] The output shaft of the servo motor 91 is fixedly installed with a storage disk 92 for driving the storage disk 92 to rotate; the storage disk 92 is provided with a plurality of storage holes evenly distributed, and each storage hole internally snaps a storage tube 93; when the storage tube 93 rotates to the working position, it is directly below the water outlet of the second water pumping assembly 7B;

[0054] The input end of the servo motor 91 is electrically connected to the output end of the PLC controller 12.

[0055] Therefore, every time a sample needs to be stored, the PLC controller 12 drives the storage disk 92 to rotate a certain angle through the servo motor 91, so as to save the water sample extracted by the second water pumping assembly 7B into a new storage tube 93 without samples; the next time storage is needed, the storage disk 92 is rotated a certain angle again, thereby realizing continuous storage of different sampling times.

[0056] In specific implementation, it further includes a wireless remote control module 10 and a storage battery 11; the input end of the PLC controller 12 is electrically connected to the output end of the storage battery 11, and the PLC controller 12 is bidirectionally electrically connected to the wireless remote control module 10. The specific installation method can be: the wireless remote control module 10 and the PLC controller 12 are installed on the front side of the installation box 2, and the storage battery 11 is installed on the lower side of the installation box 2.

[0057] A reservoir water quality monitoring device provided by the present utility model has a specific working principle as follows:

[0058] When in use, the mounting frame 1 is placed in the reservoir. After placement, the floating airbag 4 will ensure that the mounting frame 1 floats on the water surface of the reservoir. Then, the PLC controller 12 controls the motor 61. The motor 61 drives the gear 62 to rotate, the gear 62 drives the gear ring 63 to rotate, and the gear ring 63 drives the rotating pipe 51 to rotate. During the rotation of the rotating pipe 51, the top of the water inlet hose 52 can be wound around its circumferential surface. In this case, the height of the filter net barrel 53 can be adjusted, and after adjustment, water quality at different depths can be extracted.

[0059] When extracting, start two first water pumps 72, and pump the water in the reservoir into the inside of the rotating pipe 51 through the filter net barrel 53 and the water inlet hose 52. The water entering the inside of the rotating pipe 51 is divided into two paths. Part of the water enters the detection tank of the water quality detector 81 through the conical water outlet pipe 74 on the left for water quality detection, and the detected data will be stored inside the water quality detector 81. At the same time, after detection, start the second water pump 82 to pump the detected water out of the detection tank of the water quality detector 81, which is convenient for subsequent detection. The other part of the water will be pumped into the corresponding storage pipe 93 through the conical water outlet pipe 74 on the right for sample storage. After sample storage, start the servo motor 91 to rotate the storage disc 92 to rotate the storage pipe 93 without samples to directly below the conical water outlet pipe 74 on the right, which is convenient for storing samples of water at the next depth. Before sample storage, the rotation angle data of the servo motor 91 each time can be stored inside the PLC controller 12. In this case, when the servo motor 91 works, it can accurately rotate the storage pipe 93 without samples to below the conical water outlet pipe 74 on the right, which is convenient for sample storage.

[0060] The control methods of the above electrical components are all that external personnel send signals to the wireless remote control module 10 through an external wireless remote control. After receiving the signal, the wireless remote control module 10 sends the signal to the PLC controller 12, and then the PLC controller 12 controls through wireless signals.

[0061] It should be noted that the specific model of the PLC controller 12 disclosed in the above embodiments is Siemens S7-200. The water quality detector 81 can be selected as the AE86063 multi-functional water quality detector, while the motor 61, the first water pump 72, the second water pump 82, the servo motor 91, the wireless remote control module 10 and the storage battery 11 can be freely configured according to the actual application scenario. The PLC controller 12 controls the water quality detector 81, the motor 61, the first water pump 72, the second water pump 82 and the servo motor 91 to work using the commonly used methods in the existing technology.

[0062] Compared with the prior art, the beneficial effects of the present utility model are: The water quality monitoring equipment of this reservoir has the following advantages:

[0063] By setting the rotating assembly, the rotating assembly can be started according to needs during use, so that the rotating pipe rotates. During the rotation of the rotating pipe, the water inlet hose can be wound around its circumferential surface. In this case, the height of the filter net barrel can be adjusted, and after adjustment, the water quality at different depths can be extracted.

[0064] Part of the extracted water is pumped into the water quality detector for water quality detection, and the data is stored inside after the detection. The other part of the water is stored in the corresponding storage tube for sample storage. In this case, the samples are accurately detected by an external laboratory at a later stage, and then the two sets of data are compared to accurately know the water quality conditions at different depths, thereby effectively improving the accuracy of monitoring.

[0065] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
