Description

Technical Field

[0001] This invention relates to the technical field of water quality monitoring, specifically to an unmanned water quality monitoring device and its usage method. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations and trends of various pollutants, and evaluating the water quality status. The monitoring scope is very wide. In addition to monitoring items, it is sometimes necessary to measure flow velocity and flow rate. Water quality monitoring equipment on the market mainly consists of water quality sensors, data loggers, solar power systems, and buoys. The equipment can transmit water quality data wirelessly and remotely to a monitoring platform.

[0003] Chinese utility model patent CN218727190U, published on March 24, 2023, discloses a water quality monitoring system, including a base. A sliding rod is vertically fixed to the top of the base, and a water quality monitoring device is sleeved on the sliding rod. The water quality monitoring device consists of a main body, a float, and a sensor. The main body of the water quality monitoring device has a ring structure and is fitted with the sliding rod with a gap. The float is fixed to the bottom of the main body of the water quality monitoring device, and the float also has a ring structure and is fitted with the sliding rod with a gap. A detection window is opened at the bottom of the float, and the sensor is arranged in the detection window and fixedly connected to the main body of the water quality monitoring device through a mounting bracket.

[0004] The aforementioned patent involves erecting the device in a body of water, with the water quality monitoring device floating on the surface. The sensor used to monitor water quality is inserted into the water. When data is needed, it connects remotely to the water quality monitoring device, and the data monitored by the device is directly transmitted remotely, making water quality monitoring more convenient and simple. However, it requires a mechanical system to adjust the position of the water quality monitoring device. If a sudden situation occurs that causes the water level to rise rapidly, the mechanical system cannot adjust in time. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an unmanned water quality monitoring device that uses the buoyancy of water to adjust the position of the water quality monitoring components, eliminating the need for mechanical devices and allowing for faster adjustment.

[0006] This invention provides the following technical solution:

[0007] An unmanned water quality monitoring device includes a support column, a base, a buoyancy base, and a monitoring component. The bottom of the support column is fixed to the top of the base, the base is fixed to the riverbed, the support column passes through the buoyancy base and is slidably connected to the buoyancy base, the monitoring component is connected to the buoyancy base, a connecting plate is fixed to the side wall of the support column, the bottom of the connecting plate is fixed to the top of a guide rod, the guide rod passes through the buoyancy base and is slidably connected to the buoyancy base, and a threaded sleeve is threaded to the bottom of the guide rod, the bottom of the buoyancy base abuts against the top of the threaded sleeve.

[0008] Furthermore, the monitoring component includes a water collector, a protective cage, a water quality monitor, a data transmitter, and a protective cover. The water collector is fixed to the bottom of the buoyancy base, and the protective cage is provided around the water collector, with the protective cage fixed to the bottom of the buoyancy base. The water quality monitor is fixed to the top of the buoyancy base, and the data transmitter is fixed to the top of the water quality monitor. The protective cover is provided around the water quality monitor and is fixed to the buoyancy base by bolts. The water quality monitor is electrically connected to the water collector.

[0009] Furthermore, the monitoring component also includes an extension cover, a motor, a threaded rod, and impact holes. The buoyancy base has a cavity inside, the motor is disposed inside the cavity and fixed to the buoyancy base, the output shaft of the motor is fixed to the top of the threaded rod, the outer periphery of the threaded rod is threaded to the extension cover, and the bottom of the threaded rod is fixed to the top of the water collector. The bottom of the extension cover is fixed to the top of the protective cage, and the side wall of the extension cover has multiple impact holes.

[0010] Furthermore, the outer wall of the extension cover is fixed with a plurality of hinges, which are hinged to one end of the rotating plate; when the extension cover is disposed inside the buoyancy base, the rotating plate is in contact with the outer periphery of the extension cover.

[0011] Furthermore, the bottom of the threaded rod is provided with an installation groove, and a buffer device is fixed longitudinally inside the installation groove. A fixing plate is fixed on the top of the water collector, and the fixing plate is fixed to the buffer device.

[0012] Furthermore, a photovoltaic panel is provided on the top of the supporting column, and the photovoltaic panel is electrically connected to the monitoring component.

[0013] Furthermore, multiple telescopic rods are provided between the photovoltaic panel and the supporting column.

[0014] Furthermore, a connecting block is fixed to the bottom of the supporting column, and the connecting block is fixed inside the base.

[0015] A method for using an unmanned water quality monitoring device includes the following steps:

[0016] Install unmanned water quality monitoring equipment;

[0017] Debugging and monitoring components;

[0018] Real-time water quality monitoring;

[0019] Maintain the water collector.

[0020] Furthermore, the water quality maintenance collector includes the following steps:

[0021] Start the motor to fully extend the extension cover to the outside;

[0022] The rotating plate flips outward under the combined action of inertia and water flow impact;

[0023] Water flows through the impact holes to clean the surface of the water collector.

[0024] Reverse the motor to retract the extension cover.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. This invention uses the buoyancy of water to adjust the position of the water quality monitoring component, eliminating the need for mechanical devices and making adjustment faster.

[0027] 2. This invention features a buoyancy base mounted on a supporting column, upon which a water quality monitoring component is installed. The buoyancy base rises synchronously with the increasing river water level, ensuring that the water quality monitoring component is never submerged by the rising river water. Meanwhile, the water collector within the water quality monitoring component remains permanently submerged in the water.

[0028] 3. The monitoring data obtained by the water quality collector of the present invention is wirelessly transmitted to the water conservancy monitoring platform through the wireless data transmitter on the water quality monitoring instrument, so as to facilitate water conservancy personnel to keep abreast of the river water quality in real time.

[0029] 4. The sensor protective cage installed on the outside of the water collector in this invention can provide effective protection for the outside of the water collector, preventing debris in the water flow from impacting or entangled with the water collector, ensuring the long-term normal operation of the water collector, and making it more convenient for users to use.

[0030] 5. When the water collector of the present invention collects and detects water flow, the surface of the water collector will be contaminated by impurities in the water flow, which will reduce the accuracy of the water collector detection. Therefore, a retractable extension cover is designed, and impact holes are opened on the surface of the extension cover. When the surface of the water collector is contaminated, the extension cover can be released from the buoyancy base, so that the water flow can be pressurized through the impact holes to rinse the surface of the water collector, thereby maintaining the stability of the water collector monitoring data.

[0031] 6. When the extension cover of the present invention moves to the outside of the water collector, under the action of motor rotation and water flow impact, the rotating plate flips outward. The flipped rotating plate has a blocking effect on the water flow, so that different impact holes are impacted by water flow of different forces, thereby making the water flow sprayed from the impact holes onto the water collector have different impact forces, which plays a role in improving the cleaning effect.

[0032] 7. Under normal circumstances, the direction of water flow is constant. Therefore, as the extension cover moves outward from the buoyancy base, it rotates in the direction of water flow under the action of the threaded rod, making the rotating plate open relatively easily. As the extension cover moves inward from the buoyancy base, it rotates against the direction of water flow under the action of the threaded rod, making the rotating plate close relatively easily.

[0042] Please see Figure 1-7 The unmanned water quality monitoring device of this embodiment includes a support column 1, a base 3, a buoyancy base 7, and a monitoring component 8. The bottom of the support column 1 is fixed to the top of the base 3, the base 3 is fixed to the riverbed, the support column 1 passes through the buoyancy base 7 and is slidably connected to the buoyancy base 7, the monitoring component 8 is connected to the buoyancy base 7, a connecting plate 5 is fixed to the side wall of the support column 1, the bottom of the connecting plate 5 is fixed to the top of the guide rod 4, the guide rod 4 passes through the buoyancy base 7 and is slidably connected to the buoyancy base 7; a threaded sleeve 6 is threaded to the bottom of the guide rod 4, and the bottom of the buoyancy base 7 abuts against the top of the threaded sleeve 6.

[0043] When users need to monitor the water quality in outdoor rivers, they can first set up a base 3 on the side of the river, and the bottom connecting block 2 at the bottom of the support column 1 is fixed in the base 3, so that the bottom of the support column 1 is firmly set on the side of the river. A buoyancy base 7 is slidably set on the support column 1. The buoyancy base 7 itself has a large buoyancy, which allows the water quality monitoring component 8 set on it to float on the water surface.

[0044] Furthermore, the monitoring component 8 includes a water collector 802, a protective cage 805, a water quality monitor 807, a data transmitter 808, and a protective cover 810. The water collector 802 is fixed to the bottom of the buoyancy base 7, and the protective cage 805 is provided around the water collector 802. The protective cage 805 is fixed to the bottom of the buoyancy base 7. The water quality monitor 807 is fixed to the top of the buoyancy base 7, and the data transmitter 808 is fixed to the top of the water quality monitor 807. The protective cover 810 is provided around the water quality monitor 807 and is fixed to the buoyancy base 7 by bolts 809. The water quality monitor 807 is electrically connected to the water collector 802.

[0045] The water quality collector 802 in the water quality monitoring component 8 installed at the bottom of the buoyancy base 7 can be inserted into the water to monitor the water quality. The monitored data can be transmitted to the water quality monitor 807 through the data connection line. The water quality monitor 807 is equipped with a wireless data transmitter 808, which can transmit the data obtained by the water quality monitor 807 to the water conservancy workbench through wireless signals, thereby providing water conservancy staff with real-time information on the river water quality.

[0046] Furthermore, the monitoring component 8 also includes an extension cover 806, a motor 811, a threaded rod 812, and impact holes 815. The buoyancy base 7 has a cavity inside, the motor 811 is located inside the cavity and fixed to the buoyancy base 7, the output shaft of the motor 811 is fixed to the top of the threaded rod 812, the outer periphery of the threaded rod 812 is threadedly connected to the extension cover 806, and the bottom of the threaded rod 812 is fixed to the top of the water collector 802. The bottom of the extension cover 806 is fixed to the top of the protective cage 805, and multiple impact holes 815 are provided on the side wall of the extension cover 806.

[0047] When the water collector 802 collects and detects water flow, its surface can become contaminated by impurities in the water, which reduces the accuracy of its detection. Therefore, a retractable extension cover 806 is designed with impact holes 815 on its surface. When the surface of the water collector 802 becomes contaminated, the extension cover 806 can be released from the buoyancy base 7, allowing the water flow to be pressurized through the impact holes 815 and used to flush the surface of the water collector 802, thus maintaining the stability of the monitoring data from the water collector 802.

[0048] Furthermore, multiple hinges 814 are fixed to the outer wall of the extension cover 806, and the hinges 814 are hinged to one end of the rotating plate 813; when the extension cover 806 is disposed inside the buoyancy base 7, the rotating plate 813 is in contact with the outer periphery of the extension cover 806.

[0049] When the extension cover 806 moves to the outside of the water collector 802, under the action of the motor 811 rotating and the water flow impact, the rotating plate 813 flips outward. The flipped rotating plate 813 has a blocking effect on the water flow, so that different impact holes 815 are impacted by water flow of different strengths, thereby making the water flow sprayed from the impact holes 815 onto the water collector 802 have different impact forces, which plays a role in improving the cleaning effect.

[0050] Normally, the direction of water flow is constant. Therefore, as the extension cover 806 moves outward from the buoyancy base 7, it rotates in the direction of water flow under the action of the threaded rod 812, allowing the rotating plate 813 to open relatively easily. Conversely, as the extension cover 806 moves inward from the buoyancy base 7, it rotates against the direction of water flow under the action of the threaded rod 812, allowing the rotating plate 813 to close relatively easily.

[0051] Furthermore, the bottom of the threaded rod 812 is provided with an installation groove 801, and a buffer device 804 is fixed longitudinally inside the installation groove 801. A fixing plate 803 is fixed on the top of the water collector 802, and the fixing plate 803 is fixed to the buffer device 804.

[0052] The mounting groove 801 and the buffer device 804 work together to give the water collector 802 a certain amount of displacement, so that it will not be damaged under impact or other forces.

[0053] Furthermore, a photovoltaic panel 9 is installed on the top of the supporting column 1, and the photovoltaic panel 9 is electrically connected to the monitoring component 8.

[0054] Photovoltaic panel 9 converts solar energy into electrical energy, but does not monitor the power supply of component 8.

[0055] Furthermore, multiple telescopic rods 10 are installed between the photovoltaic panel 9 and the supporting column 1.

[0056] By adjusting the lengths of different telescopic rods 10, the photovoltaic panel 9 can always have a large receiving area, thus improving the performance of the photovoltaic panel 9.

[0057] Furthermore, a connecting block 2 is fixed to the bottom of the support column 1, and the connecting block 2 is fixed inside the base 3.

[0058] The stability of the connection between the support column 1 and the base 3 is improved by connecting block 2.

[0059] The method of using the unmanned water quality monitoring equipment in this embodiment includes the following steps:

[0060] Install unmanned water quality monitoring equipment;

[0061] When users need to monitor the water quality in outdoor rivers, they can first set up a base 3 on the side of the river, and the bottom connecting block 2 at the bottom of the support column 1 is fixed in the base 3, so that the bottom of the support column 1 is firmly set on the side of the river. A buoyancy base 7 is slidably set on the support column 1. The buoyancy base 7 itself has a large buoyancy, which allows the water quality monitoring component 8 set on it to float on the water surface.

[0062] Debugging and monitoring component 8;

[0063] Real-time water quality monitoring;

[0064] The water quality collector 802 in the water quality monitoring component 8 installed at the bottom of the buoyancy base 7 can be inserted into the water to monitor the water quality. The monitored data can be transmitted to the water quality monitor 807 through the data connection line. The water quality monitor 807 is equipped with a wireless data transmitter 808, which can transmit the data obtained by the water quality monitor 807 to the water conservancy workbench through wireless signals, thereby providing water conservancy staff with real-time information on the river water quality.

[0065] Maintain water collector 802;

[0066] Start motor 811 to fully extend extension cover 806 to the outside;

[0067] When the water collector 802 collects and detects water flow, its surface can become contaminated by impurities in the water, leading to a decrease in detection accuracy. Therefore, a retractable extension cover 806 is designed, with impact holes 815 on its surface. When the surface of the water collector 802 becomes contaminated, the extension cover 806 can be released from the buoyancy base 7, allowing the water flow to be pressurized through the impact holes 815 and flush the surface of the water collector 802, thus maintaining the stability of the monitoring data.

[0068] The rotating plate 813 flips outward under the combined action of inertia and water flow impact;

[0069] When the extension cover 806 moves to the outside of the water collector 802, under the action of the motor 811 rotating and the water flow impact, the rotating plate 813 flips outward. The flipped rotating plate 813 has a blocking effect on the water flow, so that different impact holes 815 are impacted by water flow of different strengths, thereby making the water flow sprayed from the impact holes 815 onto the water collector 802 have different impact forces, which plays a role in improving the cleaning effect.

[0070] Water flows through the impact hole 815 to clean the surface of the water collector 802;

[0071] The reverse motor 811 retracts the extension cover 806.

[0072] Normally, the direction of water flow is constant. Therefore, as the extension cover 806 moves outward from the buoyancy base 7, it rotates in the direction of water flow under the action of the threaded rod 812, making the rotating plate 813 open relatively easily. As the extension cover 806 moves inward from the buoyancy base 7, it rotates against the direction of water flow under the action of the threaded rod 812, making the rotating plate 813 close relatively easily.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
