TECHNICAL FIELD

[0001] The present application belongs to the field of buoy device design, and more particularly relates to a buoy with a heavy fog early warning and fog dispersing function and a fog dispersing method. BACKGROUND

[0002] A buoy is a unique floating sign on the sea and is very important for fishery and water transportation. The weather environment on the sea is very special, and harsh conditions such as wind, wave and fog put higher requirements on the performance of the buoy device. When heavy fog weather occurs, especially persistent heavy fog, the indication range of the buoy is severely limited, affecting the normal navigation of ships, and even leading to the stop of water transportation. In addition, for a large range of fog area on the shipping channel, a large amount of moisture absorbent needs to be scattered to achieve the ideal fog dispersing effect, and the pollution of the large amount of moisture absorbent to the water environment and the harm to the water organisms are worth paying attention to. Therefore, it is necessary to design a new type of buoy with a heavy fog early warning function, which can spontaneously disperse fog and is environmentally friendly. SUMMARY

[0032] The floating mechanism is used to provide buoyancy of the buoy; the heavy fog monitoring and early warning system is used to accurately locate the low-visibility section and intelligently warn in real time; the unipolar particle generator is used to generate charged particles to promote small fog droplets to collide and coalesce to form large fog droplets and naturally settle, effectively reducing the fog concentration and improving the visibility; the particle delivery system is used to deliver and diffuse the charged particles to a larger fog elimination operation area; and the power control room is used to control the start and stop of the unipolar particle generator and the particle delivery system.

[0033] In this embodiment, the floating mechanism comprises a float 15, a chain 16 and a sinker 17; the float 15 is connected to the sinker 17 through the chain 16.

[0034] In this embodiment, the heavy fog monitoring and early warning system comprises a visibility analyzer 2, a fog condition alarm lamp 1 and a positioning instrument 18.

[0035] The visibility analyzer 2 is used to monitor the visibility of the area where the buoy is located in real time; when the measured visibility is lower than the preset visibility threshold, the visibility signal controls the fog condition alarm lamp 1 to light up; the positioning instrument 18 reads the real-time position information and sends it to the remote control center in a wireless manner.

[0036] In this embodiment, the unipolar particle generator comprises a high-voltage electrode 3, a support mechanism 4 and a lifting platform 5.

[0037] The high-voltage electrode 3 is connected to the support mechanism 4 by bolts and is fixedly installed on the lifting platform 5 which can move up and down in the vertical direction; the support mechanism 4 can flexibly and quickly adjust the elevation angle of the high-voltage electrode 3, and can realize 360° rotation; the lifting platform 5 can adjust the position height of the high-voltage electrode 3, and can realize up and down movement of 0.1m-5m in the vertical direction; in this embodiment, the high-voltage electrode 3 is selected as a wire electrode, which is specifically formed by parallel winding of a stainless steel wire with a diameter of 0.1-1mm on an electrode frame, and the wire spacing is 0.5-5cm; it should be noted that the description herein is only one preferred embodiment of the application, and should not be understood as the only limitation of the application, and the high-voltage electrode can also use other structures such as needle electrode and blade electrode.

[0038] In this embodiment, the particle delivery system comprises a bellows 7, a gas delivery device 11, an air supply channel 6 and a ventilation hole 10.

[0039] The air box 7 is located below the lifting platform 5, and a gas conveying device 11 is installed inside it. The airflow generated in the air box 7 acts on the high-voltage electrode 3 through the ventilation holes 10 on the air supply channel 6, which facilitates the diffusion of charged particles into the surrounding environment and increases the fog-removing area. In this embodiment, the gas conveying device 11 is an industrial fan with 6 blades, a rated operating voltage of 220V, and a speed of 50 to 5000 r / min. It should be noted that the description here is only a preferred embodiment of the present invention and should not be construed as the only limitation of the present invention. Other devices such as fans and vacuum pumps can also be used as gas conveying devices.

[0040] In this embodiment, the power control room includes a protective chamber 13, a high-voltage DC power supply 8, an AC power supply 14, a cable winch 9, and a cable 12.

[0041] The protective chamber 13 is fixedly installed above the float 15. Inside the chamber are a high-voltage DC power supply 8, an AC power supply 14 and a cable winch 9. The high-voltage DC power supply 8 is continuously adjustable within the range of 0 to (±) 200kV, provides stable power supply, and is connected to the high-voltage electrode 3 through the cable 12. The AC power supply 14 is connected to the gas conveying equipment 11 through the cable 12.

[0042] In another embodiment of the present invention, a fog dispersal method is provided using the above-mentioned buoy with fog warning and fog dispersal functions, comprising:

[0043] S1. When the visibility in the area where one or more buoys are located is lower than a preset visibility threshold, the corresponding fog monitoring and early warning system will issue an alarm and send the real-time location information to the remote control center. For example, the preset visibility threshold can be 1 km.

[0044] S2. The remote control center determines the fog dispersal operation area and the buoys participating in the fog dispersal work based on real-time location information and the current measured minimum visibility, and allocates the installation positions of the buoys according to the principle of alternating positive and negative unipolar particle generators. For example... Figure 2 As shown, the distance between two adjacent anisotropic fog-suppressing buoys is d. ij (Subscripts i and j indicate the i-th and j-th fog-suppressing buoys, respectively.) The relative distance W between the two buoys depends on the channel width, specifically related to the bottom width of the channel cross-section and the width of vessels entering and leaving the port. According to recommendations from international shipping conferences: when overtaking is not permitted, the channel width should be 3-4 times the design vessel width; when overtaking is permitted, it should be 6-7 times the design vessel width. Alternatively, buoys can be installed only on one side of the channel, such as... Figure 3 As shown.

[0045] S3. Activate the unipolar particle generator and particle delivery system of the buoys participating in the fog dispersal work, and monitor the visibility of all buoy areas in real time.

[0046] Specifically, the high-voltage DC power supply and the AC power supply are turned on to dissipate the fog, the visibility of the fog area is monitored in real time, the voltage or current of the high-voltage DC power supply is adjusted as appropriate, the elevation angle and height of the high-voltage electrode are adjusted, the wind speed of the gas delivery device is controlled, and the diffusion area of the charged particles is changed.

[0047] For example, when the visibility of the fog area is less than 500 m, the fog concentration is high, the voltage or current of the high-voltage DC power supply is increased to generate more charged particles and shorten the fog dissipation time; when the fog is suspended at a low position, such as near the water surface, the elevation angle of the high-voltage electrode is adjusted downward and the height is lowered, so that the generated charged particles are more easily diffused in the fog accumulation area, improving the fog dissipation effect; conversely, when the fog is suspended at a high position, the elevation angle of the high-voltage electrode is adjusted upward and the height of the high-voltage electrode is raised, so that the generated charged particles are diffused in the air.

[0048] S4, when the visibility of the area where all the buoys are located is not less than the preset visibility threshold, the monopolar particle generator and the particle delivery system of the buoys participating in the fog dissipation work are turned off, and the fog dissipation is ended; otherwise, return to execute S1.

[0049] Those skilled in the art will readily understand that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, and any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
