Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality monitoring technology, specifically a water quality monitoring sampler based on the Internet of Things. Background Technology
[0002] With the rapid development of IoT technology, its application in various fields is becoming more and more widespread. Through technologies such as sensors and network communication, IoT can realize the interconnection between devices and the real-time transmission of data. In the field of water quality monitoring, IoT technology can be used to realize the automation and intelligence of water quality sampling.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN208171975U) discloses a water quality monitoring device based on the Internet of Things. A measuring tube is installed at the lower end of the float, and a weight is installed at the lower end of the measuring tube. Several water inlets are located on the upper side wall of the measuring tube, and several water outlets are located on the lower side wall. Several water quality sensors are installed on the inner lower side wall of the measuring tube, positioned above the water outlet. A waterproof box is installed at the upper end of the float, and an indicator is installed at the upper end of the waterproof box. A GPS positioning module is installed inside the indicator. A drive motor is installed in the upper middle part of the float, and the shaft of the drive motor is connected to a main shaft via a bushing. The lower side of the main shaft is located inside the measuring tube. This utility model uses the drive motor to rotate the fan blades to achieve water flow monitoring, making the monitoring data fast and accurate. It improves stability, making it less prone to capsizing in wind and waves. It also enables rapid data transmission during monitoring, improving efficiency.
[0004] The comparison document describes a method where water enters through an inlet on the top and flows out through an outlet. The water then passes through a water quality sensor, which monitors the water quality. While this method can monitor the water quality, the monitoring equipment is typically inserted directly into the water body. In practice, impurities in the freshly drawn water may contaminate and damage the water quality sensor. Furthermore, most monitoring methods only monitor localized areas of the water body, which can lead to significant errors and poor accuracy.
[0005] Therefore, this invention provides a water quality monitoring sampler based on the Internet of Things to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a water quality sampler, such as Figures 1 to 6 As shown, the device includes a housing 1, with mounting holes 101 on all sides. A drive assembly 2 is connected through the inner arc surface of the mounting holes 101. The drive assembly 2 includes two bearings 201 connected to the mounting holes 101. Each bearing 201 is connected to the other bearing 201 in pairs within the mounting holes 101. A worm gear 202 is fixedly mounted on the outer arc surface of one bearing 201, and a worm 203 is provided on the outer arc surface of the other bearing 201. The serrated part of the outer arc surface of the worm gear 202 meshes with the worm 203. One end of the worm 203 extends outside the housing 1 and is fixedly mounted with a drive wheel 204. A side plate 8 is fixedly mounted on the back of the housing 1 by bolts. The bottom of one side surface of the side plate 8 is connected to the drive wheel 204 by a rotating shaft. A synchronous belt 205 is sleeved on the outer arc surface of the two drive wheels 204.
[0029] One side of the side plate 8 can be installed on the corresponding side of the hull. At the same time, the motor starts to operate and drives the bearing 201 connected to it, thereby causing the worm gear 202 connected to the bearing 201 to rotate. When the worm gear 202 is rotating, the worm 203, which is meshed with it at the bottom, will rotate synchronously. As the worm 203 rotates, the bearing 201 on one side will penetrate to the outer area of the mounting hole 101 on one side of the housing 1. The drive wheel 204 is installed on this bearing 201, and the drive wheel 204... A timing belt 205 is fitted onto the outer arc surface. In this way, once the drive wheel 204 starts to rotate, the timing belt 205 can move up or down according to the specific rotation direction of the drive wheel 204. A brake plate 6 is fixed at one end of the timing belt 205. Then, the sampling tube 701 is fitted onto the brake plate 6, so that the depth of the sampling position of the sampling tube 701 in the water can be precisely controlled. This allows it to flexibly obtain water samples at different depths according to actual needs, thereby providing more comprehensive and accurate data information for water quality monitoring.
[0030] A connecting plate 3 is fixedly installed on the front of the housing 1. A hinge plate 4 is movably connected to the middle of one side surface of the connecting plate 3. A groove 401 is opened on the outer arc surface of the hinge plate 4. A protrusion 5 is movably engaged on the inner arc surface of the groove 401. One end of the protrusion 5 is fixedly installed on the connecting plate 3. A brake plate 6 is fixedly installed on one side surface of the synchronous belt 205 by bolts. A sleeve is provided on one side of the brake plate 6. A sampling component 7 is fixedly installed inside the sleeve on one side of the brake plate 6.
[0031] Meanwhile, to ensure that the sampling tube 701 can be positioned at each designated location, the stability of the sampling process must be guaranteed during the control operation of the motor. Therefore, a hinge plate 4 is installed at the rear end of the rotating drive wheel 204. The hinge plate 4 moves synchronously with the drive wheel 204. The groove 401 on the surface of the hinge plate 4 can play a positioning role. The principle is that a protrusion 5 is movably engaged inside the groove 401, and one side of the protrusion 5 is fixed to the stationary connecting plate 3. In this way, when the drive wheel 204 stops rotating, the protrusion 5 can be smoothly engaged inside the groove 401, thereby effectively locking the position of the sampling tube 701 and avoiding displacement deviation. This greatly improves the accuracy and stability of the sampling position and lays a solid foundation for obtaining high-quality water samples.
[0032] The sampling assembly 7 includes a sampling tube 701 that is connected through to a sleeve on one side of the brake plate 6. An extraction tube 702 is slidably engaged with the inner arc surface of the sampling tube 701. A connecting rope 703 is fixed to one end of the extraction tube 702. One end of the connecting rope 703 is wound around the hinge plate 4. An extension tube 704 is connected to the bottom of the outer arc surface of the sampling tube 701. A limiting groove 705 is provided on the side of the sampling tube 701 near the extension tube 704. A swing arm 706 is movably connected to one side of the limiting groove 705. A cover 707 is provided at one end of the swing arm 706. A sealing ring 708 is connected to one side of the cover 707. The outer arc surface of the sealing ring 708 is connected through to the inside of the extension tube 704. A hook rod 709 is connected through to one side of the swing arm 706. The top end of the hook rod 709 is connected to the extraction tube 702. A fixing plate 710 is connected to the top of the outer arc surface of the sampling tube 701. A spring 711 is connected between the fixing plate 710 and the hook rod 709.
[0033] The sampling tube 701 has a sealed top and an open bottom. When it enters the water sample area, the air inside is compressed by the incoming water, and the air is expelled through the extension tube 704 on one side. As the sampling tube 701 descends, the water pressure causes the internal sliding extraction tube 702 to rise, creating relative motion between the extraction tube 702 and the sampling tube 701. This relative motion helps to accurately obtain water samples at different depths. When the sampling tube 701 reaches the predetermined sampling depth and stops descending, the continuous water pressure and the internal air... The reaction force of the further compression of the air balances out, and the extraction tube 702 will temporarily stabilize in a specific position. At this time, the water sample is fully filled in the chamber between the sampling tube 701 and the extraction tube 702. After sampling is completed, the sampling tube 701 is brought out of the water surface by the lifting device. During this process, as the water pressure gradually decreases, the internal compressed air begins to expand, which will push the extraction tube 702 to slide downward, further sealing the water sample in a specific area at the bottom of the sampling tube 701, effectively preventing water sample leakage and external contamination, thereby ensuring the integrity of the collected water sample.
[0034] Furthermore, after the sampling operation is completed, the sealing ring 708 on one side of the cover 707 is inserted into the inside of the extension tube 704. With the tight fit between the sealing ring 708 and the inner wall of the extension tube 704, the sealing environment of the extension tube 704 is reconstructed. This seal effectively prevents the collected water from dripping during subsequent transfer, transportation or storage.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
