Description

The invention relates to hydraulic devices and is intended to indicate the boundary of the runway (runway) of a hydroaerodrome during take-off of an aircraft from its surface and landing.

A device (1) is known, which is a floating illuminated navigation sign. This device consists of a hollow plastic housing, including a float part filled with foam with a stiffener, made in the form of a metal frame of a trapezoidal shape, mounted in a plane passing through the axis of symmetry of the buoy, a silhouette figure with a central pencil case to accommodate power sources of the fender device, eyebolts and fastening the anchor chain (cable), ballast weights and foam insert in the upper silhouette of the buoy.

The disadvantage of this device is the complex construction of the buoy, time-consuming and complex manufacturing technology, the use of a large amount of metal, the absence of a keel stabilizer, and the lack of stability of the buoy on the water.

Closest to the proposed invention, selected as a prototype, is a floating navigation illuminated sign (2) made of modern polymeric materials. The device consists of a float, the body of which is made of fiberglass filled with polystyrene foam. In the lower part of the body-bottom, a ballast load of sand concrete is laid. Outside, on the underwater part of the bottom of the float body, an anchor eye is installed, and a keel shaped stabilizer is installed along its axis. On the underwater part of the buoy’s hull, a silhouette part and a sealed pencil case for night illumination are installed. In addition, on the surface of the buoy there is a metal steel fence of the backlight device, which also acts as a locator reflector. By means of a cable or kapron halyard, the buoy through the anchor eye is connected to the ballast cargo located at the bottom of the reservoir.

The disadvantages of such a device are:

a) a large windage of the surface of the buoy, under adverse weather conditions, namely when the wind and the wave arises from this, the wear of the connecting elements (cable, chain) of the buoy and ballast cargo located at the bottom of the reservoir sharply increases;

b) limited apparent buoy height;

c) high energy consumption for lighting at night;

d) the construction of the buoy is quite complicated;

e) the impossibility, due to the significant size of the buoy above the water surface and the insecurity of taxiing and take-off of a seaplane, to use buoys of this type to designate the take-off strip of a hydroaerodrome;

f) the buoy light is limited to one color;

g) when the calm of the water surface, the buoy does not contribute to the visual determination of the height above the level of the reservoir.

The technical result of the invention is to ensure the safe operation of the aircraft in take-off and landing mode at the hydroaerodrome, expanding operational capabilities.

The technical result is achieved by the fact that the device for marking the boundary of the runway of a hydroaerodrome contains a housing consisting of an illuminated surface and sealed underwater parts, with a battery case located in it, having a sand concrete load, a mounting cable, and an anchor eye. The surface and underwater parts of the housing are spaced and interconnected by a hydraulic hose, while the surface part is equipped with a radio antenna that receives radio signals, and the underwater part of the body is equipped with additional waterproof cases to accommodate the receiving control unit, the automatic pump control unit and the backlight. Also, the underwater part of the body is equipped with a hydraulic pump with the ability to supply water with adjustable intensity, shape, color and brightness of the water jet through the hydraulic hose through the nozzle fixed in the surface part of the body, and the device is equipped with a balancing weight on the hydraulic hose that stabilizes its vertical position, an additional float with passing through it an assembly cable, a hydraulic hose, an antenna wire and backlight.

A comparative analysis of the invention with identified analogues shows that it has novelty, inventive step and industrial applicability.

The essence of the invention is illustrated by a brief description and the attached drawing, where:

- in FIG. 1 shows a device for marking the boundary of a runway of a hydroaerodrome;

- in FIG. 2 shows a view A - surface part of the device;

- in FIG. 3 shows a view B - view of the underwater part of the device with a conditionally removed cover.

The device consists of a sealed underwater part of the housing 1, which is a truncated cone in shape, made, for example, of fiberglass reinforced plastic and consisting of two elements - a cover 2 and a base 3, interconnected by a fastener with corrosion resistance. To the base 3 of the underwater part of the housing 1, an reinforced sand-concrete load 4 is fixed outside, located in a plastic lining, edged along the contour with a metal profile with corrosion protection, with a fish bolt 5 on it, on which the installation and maintenance cable is fixed 6. On the base 3 inside are three water-resistant cases 7 are fixed, in which a control unit 8, an automation and backlight unit 9, and a battery unit 10 are installed. A hydraulic pump 11 is installed next to the cases; its inlet 12 through some connection is connected to the intake flange 13 disposed on the side surface of the cover 2, the flange 13 is closed intake mesh - filter 14, to prevent entry of foreign objects into the system. The outlet pipe 15 of the hydraulic pump 11 is connected to a reinforced hydraulic hose 16 passing through the pressure seal of the cover 2 to the outside. Next, the reinforced hydraulic hose 16 passes through an additional float 17 fixed on it, which is in the form of two truncated cones facing each other with their bases and consisting of a fiberglass body and an internal filler - polystyrene foam, necessary to compensate for the weight of the hydraulic hose 16 and having a mount on its surface for passing installation and operational cable 6.

The end of the reinforced hydraulic hose 16 is fixed and passes through the central holes of the above-water part of the device body 18 and the reflector 19, with the LEDs 20 mounted on it and ends with the fitting 21, with the nozzle 22 mounted on it. The surface part of the device body 18 is a truncated cone in shape with at the base of the cone of an insignificant cylindrical part, mounted on the end of a reinforced hydraulic hose 16, directed by the apex from the water surface and having at that location minimal rotivleniem aqueous medium with agitation, precluding the need for heavy ballast weights. The surface part of the housing 18 is made, for example, of fiberglass (polymer) material and has vertical channels 23 for the passage of the electric wire 24 of the LEDs 20, as well as the wire 25 of the radio control antenna 26 of the device located on the surface of the cylindrical part. The filler of the surface of the housing 18 is polystyrene foam. To stabilize the vertical position of the reinforced hydraulic hose 16, an additional metal balancing weight with corrosion protection 27 is provided, mounted on the hydraulic hose 16 below the additional float 17.

The device operates as follows.

When the VHF band signal (ultrashort waves) is supplied by the hydroaerodrome service to the device, the signal is received by the VHF antenna 26 located on the surface of the surface part of the device body 18. The control signal via electric wire 24 enters the receiver-control unit 8 located in the waterproof case 7, of the sealed underwater part housing 1 of the device. The control signal from the receiver-control unit 8 is fed to the automatic control unit of the hydraulic pump and the backlight 9. Through it, the batteries 10 located in the waterproof case 7 are connected to the hydraulic pump 11 located in the sealed underwater part of the device body 1. Similarly, through the automation unit 9 and wire 24, the backlight LEDs 20 are connected, located on the reflector 19 mounted on the surface of the surface of the device body 18. When the hydraulic pump 11 is activated, through the inlet pipe 12, with the filter 14 installed on it, water is drawn in and fed through the reinforced hydraulic hose 16 to the nozzle 21 with the nozzle 22. The water stream through the nozzle 22 is thrown onto the water surface, forming a water buoy, at the same time, it is highlighted in a certain color, indicating its location. The system of such water buoys creates the boundary of the runway of a hydroaerodrome. After taking off the aircraft, the device turns off. Since it is connected only at the time of taxiing and take-off of the seaplane, the radio control of the device is carried out in the "economical" mode.

Depending on the task, the height, shape and color of the jet device can be changed by a radio signal, providing the necessary visual shape of the buoy jet: height, color of the jet, brightness.

When the device is operated in calm, the very concept of “mirror water” is excluded, since the jet of water of the buoy falling on the “mirror” water surface creates ripples of the surface, which is sufficient for visual perception of the runway plane and creates the prerequisites for safe take-off and landing of the seaplane on the water surface pond.

Due to the location of the surface part of the device’s body at the level of the water surface and its small size, the possibility of damage to the elements of the seaplane during their contact, as well as the “sail effect” and the need to use a large mass of ballast, are excluded.

Thus, the device for marking the boundary of the runway of a hydroaerodrome solves the problem of safe operation in the mode of take-off and landing of an aircraft at a hydroaerodrome, expands operational capabilities.

The present invention is feasible according to existing technology from materials used in aircraft construction.
