Description

RIVER NAVIGATION BUOY WITH INTEGRATED HYDROPOWER INSTALLATION

The invention relates to the field of river navigation and is intended to provide a navigation path.

Known river navigation buoys having a float, the surface part in the form of a signal figure, a signal light, a power source, a balancing weight and a stabilizer in the underwater part of the buoy (1, p. 37-39).

Known hydropower plants that convert the energy of the flow of water into electricity and are installed on floats, pontoons and other boats. Such installations include a hydraulic turbine and a generator, have a long term of operation and can be used as power sources for electrical equipment of river buoys 2,3.

Of the known technical solutions, the closest in technical suction to the claimed object is a river navigation buoy with a built-in hydropower installation 4 containing a float, a surface part in the form of a signal figure, a signal light, a balancing weight and a stabilizer in the underwater part of the buoy, made in the form of a truss inside of which there is a hydraulic turbine with a vertical shaft connected to the generator shaft, enclosed in a water-proof chamber mounted on a float in the surface of the buoy.

However, the use of known designs of water protection chambers in this device is unacceptable, since they have seals in which, when the generator shaft rotates, most of the power of the turbine is lost, which significantly reduces the efficiency of the hydropower installation.

The objective of the invention is to provide reliable and high performance integrated in the buoy hydropower installation that converts the energy of the flow of water into electricity,

The completeness of the invention lies in the fact that in a river navigation buoy with a built-in hydropower installation containing a float, the surface part in the form of a signal figure, signal phoootootro z

a boom, balancing weight and stabilizer in the underwater part of the buoy, made in the form of a truss, inside which there is a hydraulic turbine with a vertical shaft connected to the generator shaft, enclosed in a water protection chamber mounted on a float in the surface of the buoy, the water protection chamber contains at least two compartment, separated by profiled partitions, each of which has a hole for the generator shaft and drainage holes for water flow.

The invention is illustrated in the drawing, which shows a schematic diagram of a waterproof chamber with two compartments. The housing 1 of the waterproof chamber is divided into compartments by profiled partitions 2 having drainage holes 3. In the upper compartment there is a generator 4, the shaft 5 of which passes through the holes in the partitions.

During operation, the river buoy may undergo short-term flooding, which requires protection of the generator from water. Waterproof camera operates as follows. When the buoy is flooded, water through the drainage holes and the gap in the hole for the generator shaft in the lower partition begins to fill the lower compartment of the chamber. The time for filling the compartment with water is determined by the number and diameter of the drainage holes in the partition. If, after filling the lower compartment, the buoy continues to be in a flooded state, then water begins to flow into the second compartment, and so on, until the buoy returns to its original floating position. After that, water through the drainage holes flows from the compartments of the waterproof chamber. Profiling partitions speeds up the process of draining water. The number of compartments is selected taking into account the time of flooding of the buoy. Usually this time is so short that it allows you to limit yourself to two partitions in a waterproof chamber.

Through drainage holes, water condensate is also removed, which is formed in the water protection chamber during generator operation.

The absence of any seals in the water protection chamber does not lead to additional power losses associated with overcoming the friction forces of the generator shaft in these seals in previously known structures.

Thus, the proposed design of the river buoy provides reliable protection and high efficiency of its hydropower installation in the conditions of short-term flooding of the buoy.
