Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to an automatic water quality monitoring and control device. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is some toxic substances, such as phenols, cyanides, arsenic, lead, chromium, cadmium, mercury, and organochlorine pesticides.

[0003] Existing water quality monitoring devices, such as the one disclosed in publication (announcement) No. CN114689813A, dated July 1, 2022, disclose a water quality monitoring system. This system includes: a monitoring and control sphere floating on the water surface; a water quality sensor connected to the sphere via an aviation connector; a device housing for installing a central control circuit inside the sphere; the central control circuit for processing the water quality information collected by the water quality sensor; and the central control circuit for reporting monitoring information.

[0004] Although the water quality monitoring system provided in this application is used for long-term remote monitoring of water quality in a certain area, the application only connects the water quality sensor by cable, making it difficult to accurately monitor water quality at different depths. Especially when there is water flow, the water quality sensor will drift with the water flow, making it difficult to monitor water quality at different depths.

[0005] Therefore, it is necessary to design an automatic water quality monitoring and control device. Utility Model Content

[0038] Please refer to Figures 1 to 4 As shown in the embodiments of this utility model,

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, an automatic water quality monitoring and control device includes a water quality monitoring component. The water quality monitoring component includes a lifting block 300, on which a rectangular chute 310 is provided. It also includes a mounting plate 100. A rectangular support column 120 is welded to the bottom center of the mounting plate 100. The rectangular support column 120 passes through the interior of the rectangular chute 310. At least four pulleys 311 are rolled on the inner wall of the rectangular chute 310 by a bracket to facilitate the smooth up and down movement of the lifting block 300. From left to right, the bottom of the lifting block 300 is equipped with a depth sensor 320, a conductivity sensor 321, a dissolved oxygen sensor 322, a pH sensor 323, a turbidity sensor 324, an ammonia nitrogen sensor 325, a total phosphorus sensor 326, a residual chlorine sensor 327, a nitrate sensor 328, and a heavy metal sensor 329.

[0040] like Figure 1 , Figure 2As shown, the drive mechanism that drives the water quality monitoring component to move up and down includes a motor 200 and a winding roller 220. The motor 200 is bolted to one side of the top of the mounting plate 100, and the winding roller 220 is rotatably mounted on the other side of the top of the mounting plate 100. The driving pulley 210 on the motor 200 and the driven pulley 223 on the winding roller 220 are connected by a belt 240. A rope 230 is wound on the winding roller 220, and the end of the rope 230 is tied to the lifting block 300. The mounting plate 100 has a through hole 110 for the rope 230 to pass through.

[0041] like Figure 1 and Figure 4 As shown, the control mechanism controls the start and stop of the drive mechanism to regulate the depth of the water quality monitoring components. The control mechanism includes an intelligent controller 400, which includes an intelligent chip 410. The input terminals of the depth sensor 320, conductivity sensor 321, dissolved oxygen sensor 322, pH sensor 323, turbidity sensor 324, ammonia nitrogen sensor 325, total phosphorus sensor 326, residual chlorine sensor 327, nitrate sensor 328, and heavy metal sensor 329 are electrically connected to the intelligent chip 410.

[0042] The conductivity sensor 321 is used to measure the conductivity of water, which can indirectly reflect the content of dissolved solids and ionic substances in water. It is suitable for laboratory, industrial production and detection fields.

[0043] The dissolved oxygen sensor 322 is used to measure the dissolved oxygen concentration in water, reflecting the water body's self-purification capacity and the degree of organic pollution.

[0044] The pH sensor 323 is used to measure the acidity or alkalinity of water by measuring the concentration of hydrogen ions in the water.

[0045] The turbidity sensor 324 is used to measure the turbidity of water, reflecting the concentration of suspended particulate matter in the water, which affects the cleanliness and transparency of the water.

[0046] The ammonia nitrogen sensor 325 is used to measure the concentration of ammonia nitrogen in water bodies, reflecting the eutrophication level of the water.

[0047] The Total Phosphorus Sensor 326 is used to measure the total phosphorus content in water to assess the degree of eutrophication and ecological status of water bodies.

[0048] The residual chlorine sensor 327 is used to measure the residual chlorine content in water and is commonly used to monitor water quality after disinfection treatment.

[0049] The nitrate sensor 328 is used to monitor the nitrate content in water, which is an important indicator of water quality pollutants.

[0050] The heavy metal sensor 329 is used to monitor the content of heavy metals such as lead and mercury in water. Heavy metals are harmful to water quality and have a certain degree of toxicity.

[0051] The intelligent chip 410 controls the start and stop of the motor 200.

[0052] like Figure 1 As shown, it also includes a solar power generation mechanism, including a solar panel 500. The solar panel 500 is mounted on the mounting plate 100 via a bracket 510. A solar controller 520 is mounted on the bottom of the solar panel 500. A storage battery 530 is mounted on the top of the mounting plate 100 near the motor 200. The solar panel 500 supplies power to the storage battery 530 via the solar controller 520. The storage battery 530 supplies power to various electrical appliances.

[0053] To facilitate the fastening of the rope 230, a screw rod 232 is screwed to the top of the lifting block 300, and a fastening ring 231 is welded to the top of the screw rod 232. The end of the rope 230 is fastened to the fastening ring 231.

[0054] like Figure 1 and Figure 3 As shown, in order to ensure smooth rotation of the winding roller 220, round shafts 221 are welded to both ends of the winding roller 220, and bearings 222 are fitted onto the outside of each round shaft 221. A driven pulley 223 is welded to the outer end of one of the round shafts 221, and the outer ring of the bearing 222 is fixedly connected to the mounting plate 100 through a bracket.

[0055] To facilitate remote monitoring, the smart chip 410 is connected to the monitoring terminal 412 via the wireless transceiver module 411. The monitoring terminal 412 can be a mobile phone, tablet, or computer.

[0056] To improve the stability of the rectangular support column 120, the lower end of the rectangular support column 120 is designed with a pointed shape, and an annular positioning plate 121 is welded to the bottom of the rectangular support column 120. At least two positioning rods 122 are welded at equal intervals to the bottom of the annular positioning plate 121.

[0057] Structural principle:

[0058] A rectangular support column 120 is installed in the water area to be measured. The depth is monitored by a depth sensor 320. The smart chip 410 controls the motor 200 to drive the winding roller 220 to rotate clockwise, which releases the rope 230. The lifting block 300 slides down the rectangular support column 120 until the set depth is reached. The smart chip 410 then controls the motor 200 to stop. The water quality is monitored by various sensors, and the motor 200 can be controlled to monitor the water quality at different depths.

[0059] The specific lifting principle of the lifting block 300 is as follows: the motor 200 drives the active belt pulley 210 to rotate clockwise, which in turn drives the driven belt pulley 223 and the winding roller 220 to rotate clockwise to release the rope 230, and the lifting block 300 descends; conversely, the motor 200 rotates counterclockwise, and the lifting block 300 rises.

[0060] The rectangular support column 120 passes through the interior of the rectangular slide 310. The inner wall of the rectangular slide 310 is equipped with at least four rollers 311 by means of a bracket, which facilitates the smooth up and down movement of the lifting block 300. At the same time, the lifting block 300 is prevented from deviating under the limiting effect of the rectangular support column 120.

[0061] The solar power generation mechanism can not only supply power to various electrical appliances, but the solar power panel 500 can also shield the drive pulley 210 and the battery 530, effectively protecting them;

[0062] The smart chip 410 is connected to the monitoring terminal 412 via the wireless transceiver module 411. The monitoring terminal 412 can be a mobile phone, tablet or computer, which facilitates remote monitoring.

[0063] It should be noted that the methods of using the various electrical appliances in this application are all prior art and will not be described in detail here.

[0064] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
