The motor is arranged 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 threadedly connected to the extension cover, and the bottom of the threaded rod is fixed to the top of the water quality collector; the bottom of the extension cover is fixed to the top of the protective cage, and a plurality of impact holes are provided on the side wall of the extension cover.

[0010] Furthermore, a plurality of hinges are fixed to the outer wall of the extension cover, and the hinges are hinged to one end of the rotating plate; when the extension cover is arranged inside the buoyancy base, the rotating plate fits the outer periphery of the extension cover.

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

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

[0013] Furthermore, a plurality of telescopic rods are arranged between the photovoltaic panel and the supporting column.

[0014] Furthermore, a connecting block is fixed at 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 comprises the following steps:

[0016] Install unmanned water quality monitoring equipment;

[0017] Debug monitoring components;

[0018] Real-time monitoring of water quality;

[0019] Maintain water quality collectors.

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

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

[0022] The rotating plate turns outward under the combined effect of inertia and water impact;

[0023] The water flows through the impact holes to clean the surface of the water collector;

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

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention uses the buoyancy of water to adjust the position of the water quality monitoring component without using mechanical devices, and the adjustment is faster.

[0027] 2. The present invention is provided with a buoyancy base on the supporting column, and a water quality monitoring component is provided on the buoyancy base, wherein the buoyancy base can move upward synchronously with the rise of the river water level, thereby ensuring that the water quality monitoring component provided on the buoyancy base will never be submerged by the rising river water, and the water quality collector in the water quality monitoring component can always be inserted 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 monitor, so that the water conservancy personnel can grasp the river water quality in real time.

[0029] 4. The sensor protection cage arranged on the outside of the water collector of the present invention can provide effective protection for the outside of the water collector, prevent debris in the water flow from colliding with or entangled with the water collector, ensure the long-term normal operation of the water collector, and make it more convenient for users to use.

[0030] 5. When the water quality collector of the present invention collects and detects water flow, the surface of the water quality collector will be contaminated by impurities in the water flow, resulting in reduced detection accuracy of the water quality collector. Therefore, a retractable extension cover is designed, and an impact hole is opened on the surface of the extension cover. When the surface of the water quality collector is contaminated, the extension cover can be released from the buoyancy base, so that the water flow is pressurized through the impact hole and then flushes the surface of the water quality collector, so as to maintain the stability of the monitoring data of the water quality collector.

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

[0032] 7. Under normal circumstances, the flow direction of water is unchanged. Therefore, when the extension cover moves toward the outside of the buoyancy base, the extension cover rotates along the direction of the water flow under the action of the threaded rod, so that the rotating plate can be opened more easily; when the extension cover moves toward the inside of the buoyancy base, the extension cover rotates against the direction of the water flow under the action of the threaded rod, so that the rotating plate can be closed more easily.

[0042] See also Figure 1-7 The unmanned water quality monitoring equipment of this embodiment includes a supporting column 1, a base 3, a buoyancy base 7 and a monitoring component 8. The bottom of the supporting column 1 is fixed to the top of the base 3, the base 3 is fixed to the riverbed, the supporting 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 supporting 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 screw sleeve 6 is threadedly connected to the bottom of the guide rod 4, and the bottom of the buoyancy base 7 abuts against the top of the screw sleeve 6.

[0043] When the user needs to monitor the water quality in an outdoor river, the user can first set the base 3 on the side of the river, and the bottom connecting block 2 at the bottom end of the supporting column 1 is fixed in the base 3, so that the bottom of the supporting column 1 is firmly set on the side of the river, and a buoyancy base 7 is slidably set on the supporting column 1. The buoyancy base 7 itself has a large buoyancy, which can make the water quality monitoring component 8 set thereon float on the water surface.

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

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

[0046] Furthermore, the monitoring component 8 also includes an extension cover 806, a motor 811, a threaded rod 812 and an impact hole 815. A cavity is opened inside the buoyancy base 7. The motor 811 is arranged 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. The bottom of the threaded rod 812 is fixed to the top of the water quality collector 802; the bottom of the extension cover 806 is fixed to the top of the protective cage 805, and a plurality of impact holes 815 are opened on the side wall of the extension cover 806.

[0047] When the water collector 802 collects and detects the water flow, the surface of the water collector 802 will be contaminated by impurities in the water flow, resulting in a decrease in the detection accuracy of the water collector 802. Therefore, a retractable extension cover 806 is designed, and an impact hole 815 is opened on the surface of the extension cover 806. When the surface of the water collector 802 is contaminated, the extension cover 806 can be released from the buoyancy base 7, so that the water flow is pressurized through the impact hole 815 and then flushes the surface of the water collector 802, so as to maintain the stability of the monitoring data of the water collector 802.

[0048] Furthermore, a plurality of 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 fits the outer periphery of the extension cover 806 .

[0049] When the extension cover 806 moves to the outside of the water collector 802, the rotating plate 813 flips outward under the action of the rotation of the motor 811 and the impact of the water flow. The flipped rotating plate 813 has a blocking effect on the water flow, so that different impact holes 815 are impacted by water flows of different intensities, and then the water flow sprayed from the impact holes 815 to the water collector 802 has different impact forces, which improves the cleaning effect.

[0050] Normally, the flow direction of the water flow is constant. Therefore, when the extension cover 806 moves toward the outside of the buoyancy base 7, the extension cover 806 rotates along the direction of the water flow under the action of the threaded rod 812, so that the rotating plate 813 can be opened more easily; when the extension cover 806 moves toward the inside of the buoyancy base 7, the extension cover 806 rotates against the direction of the water flow under the action of the threaded rod 812, so that the rotating plate 813 can be closed more easily.

[0051] Furthermore, a mounting groove 801 is formed at the bottom of the threaded rod 812 , a buffer device 804 is longitudinally fixed inside the mounting 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 cooperate to allow the water collector 802 to have a certain displacement, so that it will not be damaged when subjected to impact or other forces.

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

[0054] The photovoltaic panel 9 converts solar energy into electrical energy, and the monitoring component 8 supplies power.

[0055] Furthermore, a plurality of telescopic rods 10 are arranged 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 larger receiving area, thereby improving the use effect of the photovoltaic panel 9 .

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

[0058] The connection block 2 improves the stability of the connection between the support column 1 and the base 3.

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

[0060] Install unmanned water quality monitoring equipment;

[0061] When the user needs to monitor the water quality in an outdoor river, the user can first set the base 3 on the side of the river, and the bottom connecting block 2 at the bottom end of the supporting column 1 is fixed in the base 3, so that the bottom of the supporting column 1 is firmly set on the side of the river, and a buoyancy base 7 is slidably set on the supporting column 1. The buoyancy base 7 itself has a large buoyancy, which can make the water quality monitoring component 8 set thereon float on the water surface.

[0062] Debug monitoring component 8;

[0063] Real-time monitoring of water quality;

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

[0065] Maintain water quality collector 802;

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

[0067] When the water collector 802 collects and detects the water flow, the surface of the water collector 802 will be contaminated by impurities in the water flow, resulting in a decrease in the detection accuracy of the water collector 802. Therefore, a retractable extension cover 806 is designed, and an impact hole 815 is opened on the surface of the extension cover 806. When the surface of the water collector 802 is contaminated, the extension cover 806 can be released from the buoyancy base 7, so that the water flow passes through the impact hole 815 and is pressurized to flush the surface of the water collector 802, so as to maintain the stability of the monitoring data of the water collector 802.

[0068] The rotating plate 813 is turned outward under the combined effect of inertia and water flow impact;

[0069] When the extension cover 806 moves to the outside of the water collector 802, the rotating plate 813 flips outward under the action of the rotation of the motor 811 and the impact of the water flow. The flipped rotating plate 813 has a blocking effect on the water flow, so that different impact holes 815 are impacted by water flows of different intensities, and then the water flow sprayed from the impact holes 815 to the water collector 802 has different impact forces, which improves the cleaning effect.

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

[0071] The motor 811 is reversed to retract the extension hood 806 .

[0072] Normally, the flow direction of the water flow is unchanged. Therefore, when the extension cover 806 moves toward the outside of the buoyancy base 7, the extension cover 806 rotates along the direction of the water flow under the action of the threaded rod 812, so that the rotating plate 813 can be opened more easily; when the extension cover 806 moves toward the inside of the buoyancy base 7, the extension cover 806 rotates against the direction of the water flow under the action of the threaded rod 812, so that the rotating plate 813 can be closed more easily.

[0073] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
