Description

Self-balancing buoy device

Technical Field

The present invention relates to buoys, and more particularly, to a self-balancing buoy device.

Background

In the ocean, large river, reservoir and other water areas of China, the application of the buoy is very wide, and various buoys are tens of thousands. The buoy is anchored to the water bottom through an anchor chain to fix the position, and is used as a navigation mark, and the buoy is used for marking the range of a navigation channel and indicating a shoal or an obstacle endangering navigation safety. The buoy is arranged on the water area with the navigation function in day and night, is provided with a light-emitting lamp, is called as a lamp buoy and is used for assisting navigation in the water area with the navigation function in day and night; some buoys also contain radar transponders, radio beacons, fog warning signals, etc.

At present, buoys for technical use are also increasing, such as for monitoring water level, water quality, water temperature, etc., for sea, large river investigation, etc. The buoy is provided with an anchor chain so as to be fixed on the water bottom, but under the scene of stormy waves or when people climb on the platform, load unbalance naturally occurs, the water level can severely fluctuate up and down, and the buoy is caused to swing variably, so that the buoy is difficult to play a normal role, and the service time of the buoy is shortened.

Under the impact of wind and wave, the common buoy is inclined to the east and west, equipment at the top of the buoy is often affected by water, and in order to reduce the inclination of the buoy, the size of the buoy is sometimes only increased, so that the manufacturing cost of the buoy is increased.

In practical applications, most buoys need to be stable, especially technical buoys. In order to obtain accurate technical parameters, the buoy cannot swing indefinitely. The most applicable navigation mark also needs to be stable, so that the navigation mark is clearly visible, and personnel can conveniently mount the navigation mark on the buoy for construction or maintenance. For buoy management, the most common work is buoy rush repair, particularly when a navigation mark is abnormal in offshore rush repair, attack of strong wind and sea waves is often encountered, and the buoy swings very severely, so that maintenance work of maintenance personnel is affected, and life safety of the maintenance personnel is threatened.

In addition, in water areas such as rivers, reservoirs, farms and the like, if buoys for water level monitoring, water quality monitoring and water temperature monitoring swing variably, stability and accuracy of monitoring data can be seriously affected.

In summary, the conventional buoy generally used at present swings variably under the action of stormy waves or during installation and maintenance of a personnel stage, so that normal use of the buoy is affected, personnel operation is affected, and damage to the buoy is caused. The buoy belonging to the technical class can seriously influence the stability and accuracy of monitoring data if the buoy swings variably.

Thus, there is a need for a buoy having an automatic balancing device.

when the floating body 32 is immersed in water, the floating body 32 exerts buoyancy on the tag body 1 through the cantilever 31 to resist the overturning moment generated on the tag body 1 by external force (such as wind waves, staff, etc.).

In the present invention, all the cantilever rods 31 are circumferentially uniformly at the outer periphery of the body 1, and preferably, the balancing device 3 includes 4 to 6 cantilever rods 31, and 4 to 6 cantilever rods 31 are circumferentially arranged at the outer periphery of the body 1.

The specific principle of the self-balancing buoy device of the invention is as follows:

(1) Still water state: when the wind wave is calm or the wind wave is small, the tag body 1 is relatively stable, and the balance device 3 is in a non-working state, i.e. the floating body 32 is suspended at the second end of the cantilever 31 and is in a balance state.

(2) When the wind and wave load or the staff load received by the tag body 1 is uneven: when the wind wave is large or the staff is arranged on the bearing surface of the mark body 1, the mark body 1 can incline to one side, when the inclination angle of the mark body 1 relative to the water surface reaches the design requirement, the floating body 32 positioned on the inclined side of the mark body 1 can be immersed into water to generate buoyancy, and anti-overturning moment is provided for the mark body 1, so that stable balance of the mark body 1 is realized.

(3) Balance calculation: under the action of external load, the above-mentioned sign body 1 must meet the static balance condition, i.e. the sum of vertical external load acting on the sign body 1 is equal to zero, and the sum of moment of external load to any point of sign body 1 is equal to zero.

As the first embodiment of the above-described tag body 1: the tag body 1 includes a buoyancy tank 11 made of a water-impermeable material (such as steel, plastic, etc.). When in use, the top surface of the buoyancy tank 11 is 0.3-0.5 m higher than the static water level, and the part below the water surface provides buoyancy.

As shown in fig. 1 and 2, in order to lower the center of gravity of the body 1 and reduce the swing amplitude of the body 1, a housing cavity 111 is provided in the buoyancy tank 11, and a counterweight 112 (e.g., a concrete block) is provided in the housing cavity 111. The weight body 112 is preferably fixed at the center of the receiving chamber 111.

As a second embodiment (not shown) of the tag body 1, there is provided: the tag body 1 comprises a foam plastic body (such as EPS) with a hard closed-cell structure, and a coating layer or a coating net is arranged on the surface of the foam plastic body.

In order to facilitate the installation of external devices, the top of the tag body 1 is provided with a bracket 4 for installing the external devices. The bracket 4 may be made of steel plate. The external device is one of a detector (such as radar, etc.), a guide (such as navigation lights, etc.), and a solar power generator (solar panel).

The tag body 1 has a holder ring 12 to which the cantilever rods 31 are mounted, and first ends of all the cantilever rods 31 are fixed to the holder ring 12. The top round edge of the support ring 12 is higher than the bearing surface of the tag body 1, and a drain hole is arranged on the part of the support ring 12 close to the bearing surface.

The cantilever 31 may be a circular arc rod, so that the buoyancy generated by the floating body 32 is axially transferred to the second end of the cantilever 31, and then axially transferred to the body 1 through the first end of the cantilever 31.

The float 32 may be solid or hollow (e.g., a float, pontoon, etc.). Preferably, the floating body 32 is formed of a floating ball.

In order to increase the integrity of the balance device 3, two circumferentially adjacent floating bodies 32 are connected by a connecting rod 33. Further, in order to generate buoyancy for the connecting rod 33, the connecting rod 33 is an arc hollow pipe, and the centers of the circles corresponding to all the arc hollow pipes are coincident.

The anchor 2 and the anchor chain 5 are conventional members. The anchor 2 is submerged in the water, the anchor chain 5 connects the anchor 2 and the body 1, so that the body 1 can rise or drift along with the water level, and the length of the anchor chain 5 is enough to pull the body 1 at the highest water level.

In summary, the self-balancing buoy device provided by the invention can resist the overturning moment generated by the wind wave load or the staff load, and automatically realize the balance of the buoy body, so that the stability of the buoy body is improved. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
