Abstract
Description
Technical Field
[0001] This utility model relates to a water quality monitoring device, and more particularly to a mobile water level and water quality monitoring device. Background Technology
[0002] Surface water includes rivers, lakes, canals, channels, reservoirs, wetlands, and estuaries. Long-term monitoring of surface water quality parameters helps water conservancy departments understand long-term changes in surface water quality, which is beneficial for protecting and improving the aquatic ecological environment. At the same time, it can provide quantitative data and decision-making basis for events such as algal blooms, fish deaths, and suspended solids entrainment.
[0003] Water quality monitoring stations typically use box-type equipment, fixedly installed at locations such as riverbanks. They periodically or continuously collect water samples and perform multiple water quality parameter tests inside the station, then remotely transmit the results to a cloud platform. However, due to their fixed installation, monitoring stations can only conduct point-to-point water quality monitoring of a specific area, and the monitoring area is limited to the periphery of the water body, making it difficult to test the water quality in the central area. Summary of the Invention
[0004] This invention provides a mobile water level and water quality monitoring device, which solves the problem that existing fixed water quality monitoring equipment cannot be moved freely and cannot monitor the central area of the water body.
[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a mobile water level and water quality monitoring device, comprising: a buoy base, a storage battery, a centrifugal pump, a control circuit board, a positioning module, and a water quality detection probe; the buoy base is composed of an upper water chamber, a buoyancy body, and an underwater chamber, the storage battery, the control circuit board, and the positioning module are all located in the upper water chamber, which can reduce the waterproof requirements; the centrifugal pump is composed of a motor and a centrifugal impeller fixed on the buoy base; the underwater chamber is divided into a detection chamber and a centrifugal chamber, the detection chamber and the centrifugal chamber are connected, the centrifugal impeller is located in the centrifugal chamber, the outer wall of the centrifugal chamber is provided with a drainage hole, the detection chamber is provided with a water inlet protective cover and a filter screen, the water quality detection probe is located in the detection chamber, the detection chamber is provided with several partitions, dividing the detection chamber into several sub-detection chambers, each of the sub-detection chambers has one and only one water quality detection probe.
[0006] This invention relates to a buoy-type water quality monitoring device, which can be deployed or retrieved from a ship and freely placed in various areas of open water. The buoy base generates buoyancy, allowing the entire buoy base to float on the water surface. The control circuit board electrically controls a centrifugal pump, a positioning module, and water quality detection probes. The centrifugal pump drives the water flow, causing water in the centrifugal chamber to flow out through the drain hole, allowing external water to flow into the monitoring chamber through the inlet protective cover, thus achieving water exchange within the monitoring chamber. The positioning module receives positioning signals from BeiDou or GPS to determine its three-dimensional coordinates, thereby determining its current position and water level for monitoring water level. The water quality detection probes include, but are not limited to, ORP sensors, pH sensors, conductivity sensors, residual chlorine sensors, turbidity sensors, and ammonia nitrogen sensors. Each sub-monitoring chamber has one and only one water quality detection probe to prevent interference between different probes and avoid inaccurate test results. When performing testing, this invention requires first starting the centrifugal pump to change the water in the testing chamber, then stopping the centrifugal pump and starting the water quality testing probe to test the water.
[0007] Furthermore, the underwater chamber is composed of an outer circular tube, a circular annular partition, and an inner circular tube. The upper end of the outer circular tube is connected to the bottom of the buoyancy body. The outer edge of the circular annular partition is connected to the inner wall of the outer circular tube, and its inner edge is connected to the upper end of the inner circular tube. The inner circular tube is provided with a cover. The centrifugal chamber is formed on the upper side of the circular annular partition, and the detection chamber is formed on the lower side of the circular annular partition. The inner circular tube is provided with a connecting hole connecting the centrifugal chamber and the detection chamber. The water inlet protective cover is located at the lower end of the outer circular tube. The centrifugal impeller is located at the center of the centrifugal chamber and its rotation axis is vertical.
[0008] Furthermore, at the bottom of the buoyancy body and outside the outer tube, several resistance plates arranged in a circular array are vertically positioned. The inner ends of the resistance plates are deflected to one side, with the deflection direction consistent with the rotation direction of the centrifugal impeller. Since the centrifugal impeller exerts a directional force on the device during operation, causing it to tend to rotate in the opposite direction, the resistance plates mitigate this rotational effect. Simultaneously, the water flow from the drain hole exerts a thrust perpendicular to the plate surface on the deflected resistance plates, which is opposite to the direction of the reverse rotation, thus further mitigating the rotational effect.
[0009] Furthermore, a vertically upward anti-sway rod is fixedly connected to the lower end of the inner tube, and a counterweight is provided at the lower end of the anti-sway rod. Through the above technical solution, the center of gravity of this invention can be significantly lowered, thereby improving its resistance to wind and waves. Simultaneously, the longer anti-sway rod generates a greater damping effect when this invention swings, further enhancing its anti-sway effect.
[0010] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model is a buoy-type water body detection device that can be deployed or retrieved by a ship and can be freely deployed to various areas of open water, with a wide detection range; 2. When conducting detection, this utility model requires first starting a centrifugal pump to change the water in the detection chamber, then stopping the centrifugal pump and starting the water quality detection probe to detect the water body. This ensures that the water in the detection chamber is completely consistent with the external water body, ensuring the reliability of the detection results. Attached Figure Description

[0016] Example 1: See Figure 1 , Figure 2 and Figure 3A mobile water level and water quality monitoring device includes: a buoy base 100, a battery 10, a centrifugal pump 20, a control circuit board 30, a positioning module, and a water quality detection probe 40. The buoy base consists of an upper water chamber 110, a buoyancy body 120, and an underwater chamber 130. The battery, control circuit board, and positioning module are all located in the upper water chamber. The centrifugal pump consists of a motor 21 and a centrifugal impeller 22 fixed on the buoy base. The underwater chamber is divided into a detection chamber 140 and a centrifugal chamber 150, which are connected. The centrifugal impeller is located in the centrifugal chamber, and the motor is installed in the buoyancy body. The outer wall of the centrifugal chamber has a drain hole 151. The detection chamber has a water inlet protective cover 141 and a filter screen 142. The water quality detection probe is located in the detection chamber. The detection chamber has three partitions 143, which divide the detection chamber into three sub-detection chambers 144. Each sub-detection chamber has one and only one water quality detection probe.
[0017] This is a buoy-type water quality monitoring device that can be deployed or retrieved from a ship and can be freely deployed to various areas of open water. The buoy base has a buoyancy body to generate buoyancy, allowing the entire buoy base to float on the water surface. The control circuit board electrically controls the centrifugal pump, positioning module, and water quality detection probes. The centrifugal pump drives the water flow, causing water in the centrifugal chamber to flow out through the drain hole, allowing external water to flow into the monitoring chamber through the inlet protective cover, thus achieving water exchange within the monitoring chamber. The positioning module receives positioning signals from BeiDou or GPS to determine its own three-dimensional coordinates, thereby determining its current position and water level for monitoring water level. The water quality detection probes consist of three of the following: ORP sensor, pH sensor, conductivity sensor, residual chlorine sensor, turbidity sensor, and ammonia nitrogen sensor. Each sub-monitoring chamber has exactly one water quality detection probe to prevent interference between different probes and avoid inaccurate test results. When conducting the test, the centrifugal pump must first be started to change the water in the test chamber, then the centrifugal pump must be stopped, and the water quality test probe must be started to test the water.
[0018] See Figure 1 The underwater chamber is composed of an outer circular tube 131, a circular baffle 132, and an inner circular tube 133. The upper end of the outer circular tube is connected to the bottom of the buoyancy body. The outer edge of the circular baffle is connected to the inner wall of the outer circular tube, and its inner edge is connected to the upper end of the inner circular tube. The inner circular tube is provided with a cover 134. A centrifugal chamber is formed on the upper side of the circular baffle, and a detection chamber is formed on the lower side of the circular baffle. A connecting hole 135 is provided on the inner circular tube to connect the centrifugal chamber and the detection chamber. A water inlet protective cover is located at the lower end of the outer circular tube. The centrifugal impeller is located in the center of the centrifugal chamber and the shaft is vertical.
[0019] See Figure 1 and Figure 3At the bottom of the buoyancy body, and on the outer side of the outer tube, are several resistance plates 160 arranged in a circular array. The inner ends of the resistance plates are deflected to one side, in the same direction as the rotation of the centrifugal impeller. Since the centrifugal impeller exerts a directional force on the body during operation, causing it to tend to rotate in the opposite direction, the resistance plates mitigate this rotational effect. Simultaneously, the water flow from the drain hole generates a thrust perpendicular to the plate surface on the deflected resistance plates, which is opposite to the direction of the reverse rotation, further mitigating the rotational effect.
[0020] See Figure 1 The lower end of the inner tube is fixedly connected to a vertically upward anti-sway rod 170, and the lower end of the anti-sway rod is equipped with a counterweight 171. Through the above technical solution, the center of gravity of the device can be significantly lowered, thereby improving the device's resistance to wind and waves. At the same time, the longer anti-sway rod will generate a greater damping effect when the device swings, further enhancing the anti-sway effect.
[0021] See Figure 1 The buoyancy body consists of a support frame 121 and hollow plastic floats 122; a photovoltaic panel 111 is installed on the outside of the floating tank; the control circuit board contains a control chip, a storage unit, and a communication module. The photovoltaic panel can power the battery, the storage unit can be used to store the collected data, and the communication module can enable data exchange between this invention and the cloud via wireless transmission.
[0022] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
