Description

Technical Field

[0001] The invention relates to the technical field of water quality online monitoring, and in particular to a self-positioning water quality online monitoring buoy. Background Art

[0002] In order to protect the water environment and realize water environment risk warning, online monitoring of water bodies is essential. At present, the buoys used for water body monitoring are generally fixed. If multi-point monitoring is required, multiple buoys are required. Existing buoys can generally only be fixed at a certain position, with a limited monitoring range and low efficiency, and cannot effectively monitor the water environment and water quality characteristics of vast waters. If multiple buoys are used for networking monitoring, the cost of the monitoring system will be greatly increased. In addition, existing buoys generally only realize specific water body online monitoring functions, such as online water quality monitoring, online cyanobacteria monitoring, etc. The system has poor openness and relatively single test indicators, which cannot meet the diverse needs of users.

[0003] Therefore, patent CN 101776676 A discloses a mobile water body online comprehensive monitoring buoy, but the structure of the propeller of the monitoring buoy is not reasonable enough and cannot meet the actual needs. Summary of the invention

[0004] The purpose of the present invention is to provide a self-positioning water quality online monitoring buoy for freshwater slow-flow water bodies in view of the technical defects existing in the prior art.

[0005] The technical solution adopted to achieve the purpose of the present invention is:

[0006] A self-positioning buoy for online water quality monitoring comprises a buoy body, a solar panel is installed on the upper end of the buoy body, a battery and a circuit board are installed in the installation compartment of the buoy body, and an online water quality sensor is vertically installed through the installation hole at the bottom of the installation compartment, and a thruster is provided at the bottom of the buoy body, the thruster comprises three horizontally arranged ducted thrusters in three ducts arranged at the same position at the lower part of the buoy body, the ducts extend radially horizontally to the inside and then extend downward to the bottom of the buoy body; two ducted thrusters are symmetrically arranged in an "eight" shape on both sides of the axis direction of the third ducted thruster, the axis of the third ducted thruster intersects with the center line of the buoy body, and the three ducted thrusters are located on the same side of the longitudinal center plane of the buoy body which is perpendicular to the axis of the third ducted thruster.

[0007] Further, as a preference, the mounting hole is formed at the center of the buoy body.

[0008] Further, preferably, the bottom portion and the side portion of the buoy body are connected by an arc portion.

[0009] Further, as a preference, the GPS locator connected to the circuit board is arranged on the top of the buoy body. The GPS locator can be used to locate the position of the buoy.

[0010] The present invention can realize the self-navigation function by adding a ducted propeller to a conventional water quality online monitoring buoy, thereby achieving safe and convenient deployment and recovery; at the same time, the buoy is powered by solar energy to meet the power requirements of the water quality sensor and the underwater propeller, thereby achieving long-term self-sustaining online monitoring.

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] like Figure 1-3 As shown, the water self-positioning quality online monitoring buoy of the present invention comprises:

[0020] The buoy body 1 is made of polyurea material, and a solar panel 2 is installed on the upper end of the buoy body. The number of solar panels 2 can be set according to needs, such as 4 in the present invention. Figure 1-3As shown, it is arranged obliquely on the four upper inclined surfaces of the buoy body 1, and a battery 8 (for powering the electrical equipment of the buoy) and a circuit board 5 (control system) are installed in the installation compartment of the buoy body, and a water quality online sensor 4 is vertically installed through the installation hole at the bottom of the installation compartment. The battery and the circuit board are respectively connected to the propeller to power the propeller and drive the propeller to move, and the battery is also connected to the circuit board to power its operation; the above-mentioned structures are all conventional buoys in the prior art, wherein the structure of the circuit board can be implemented by the circuit board structure disclosed in CN 101776676 A.

[0021] The innovation of the present invention lies in that the power system includes three horizontally arranged ducted thrusters 6 in three ducts arranged at the same position at the lower part of the buoy body, the ducts extend radially horizontally to the inside and then extend downward to the bottom of the buoy body; two ducted thrusters are symmetrically arranged in an eight-shaped shape on both sides of the axial direction of the third ducted thruster, the axis of the third ducted thruster intersects with the center line of the buoy body, and the three ducted thrusters are located on the same side of the longitudinal center plane of the buoy body perpendicular to the axis of the third ducted thruster.

[0022] Further, as a preference, the mounting hole is formed at the center of the buoy body.

[0023] Further, as a preference, the bottom surface and the side surface of the buoy body are connected by an arc portion. The top surface of the buoy body is a plane, such as forming a rectangular plane structure, such as Figure 1-3 shown.

[0024] Furthermore, as a preferred embodiment, a GPS locator 3 is installed on the top of the buoy body and connected to the circuit board 5. The buoy can be positioned by the GPS locator. In addition to providing location information for monitoring water quality (location geographic information can be displayed on a remote monitoring interface), the GPS locator can also control the action of the ducted propeller set on the buoy through the circuit board, so that the buoy always works at the positioning point. For example, when the buoy is offset due to environmental factors such as wind, the buoy propeller is controlled to work through GPS data and the corresponding control program, so that the buoy always works at the positioning point.

[0025] It should be noted that by setting up solar panels, a solar power supply system is formed, which can meet the power supply needs of monitoring equipment and positioning equipment when the equipment is deployed for a long time.

[0026] It should be noted that, in the present invention, the ducted thrusters are used for positioning the buoy, that is, controlling the movement of the buoy. When the buoy is offset to a certain position, three ducted thrusters deployed in an eight-shaped pattern start working to push the buoy to the initial deployment point.

[0027] In order to control the buoy more conveniently, a remote controller 7 is provided to control the buoy. Figure 4-5 As shown, the remote controller 7 is provided with a buoy operation cross key 11 to control the forward, backward, left and right movement of the buoy, a power switch 10 (used to power on or off the remote controller), a positioning switch 9 (used to turn on or off the positioning function of the buoy), a power indicator light 13 (used to light up when powered on), a positioning indicator light 12 (when the light is on, it means the positioning switch is on and positioning is in progress, otherwise the light is off), a pairing indicator light 14 (used to light up when the remote controller communicates with the buoy and the pairing is successful), and a communication antenna is provided.

[0028] 1. The deployment process of the buoy is as follows:

[0029] 1) Power on the buoy and place it into the water from the shore;

[0030] 2) Turn on the remote control, pair it with the code, and control the buoy to the monitoring point;

[0031] 3) Use the positioning switch 9 on the remote control to position the buoy; after positioning, the buoy can be self-sustaining within a diameter of 3m at the positioning point;

[0032] 4) The buoy can monitor water quality and transmit data in real time; the buoy can work for a long time;

[0033] 5) The buoy can work independently for a long time according to actual use needs.

[0034] 2. The buoy recovery process is as follows:

[0035] 1) Power on the remote control and pair it with the code;

[0036] 2) After successful binding, move the buoy to the required remote control point;

[0037] 3) Bring the buoy to the surface and turn off the power;

[0038] 4) The work is completed.

[0039] The present invention has the following characteristics:

[0040] 1) Small size and light weight: It is easy to carry for field operations and can be deployed by one person;

[0041] 2) Flexible deployment: The underwater propeller can be controlled by a remote control to achieve self-navigation, thereby controlling the buoy to move to any working point, and the monitoring point can be changed at any time on shore.

[0042] 3) Self-positioning without anchoring: The buoy controls the thruster through the GPS locator, thereby maintaining the measurement point positioning by itself, without the need to anchor or remove the buoy.

[0043] 4) Convenient and safe recovery: When recovering the buoy, personnel do not need to go into the water. They only need to remotely control the underwater propeller to return from the monitoring point to the recovery point. At the same time, due to the use of GPS positioning and control technology, there is no need to anchor or remove the buoy, reducing the risk of personnel going into the water in dangerous waters.

[0044] 5) Self-powered: Powered by solar panels, the power supply can meet the long-term power supply of water quality sensors and circuit board ducted thrusters;

[0045] 6) Online monitoring and real-time transmission of water quality data: Water quality data is monitored online in real time through water quality sensors and transmitted to the monitoring platform in real time through the 4G communication network.

[0046] 7) Safety of deployment and recovery: GPS positioning and control technology is used, eliminating the need to anchor or remove buoys, reducing the risk of personnel entering the water in dangerous waters.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
