Description

DESCRIPTION of the industrial invention with TITLE:

RIVER UNDERGROUND WITH BOUND GUIDE

The present invention describes a highly innovative solution, but substantially simple from the construction point of view, which allows to transform any river that flows in the urban section of a city into a real subway line with bound guide for the transport of passengers.

It should be specified here that it is not a question, therefore, of a passenger transport with more or less traditional boats on the waters of a river but of a real metropolitan service with boats (1) that are linked to motorized trolleys (3) that run on rails submerged (6) and which therefore allow accelerations, decelerations and maneuvers completely similar to those performed by trains with obvious advantages for the transport capacity of the line which can therefore easily reach 15,000 pax / h like a real underground line.

A planing hull boat (1) is bound by pantographs (2) to motorized carriages (3) which run on submerged rails (6) being these carriages formed by a protective hood, electric motors in submerged execution (10), gears for power transmission (12) and main wheels (11).

Below the main wheels (11) are installed small wheels (13) to the submerged rails (6), also called contrast wheels, which have the double function of increasing the adhesion to the rails (6) of the wheels (11) and to prevent said wheels (11) from derailing since they, unlike normal land convoys, are subject to a fairly limited vertical load due to Archimedes' thrust on the boats. The power supply comes from a traditional electric line (18) on which appropriate pantographs (4) of the railway type run but much increased in length to be able to follow the variations in the river level during periods of flood or low water.

In fig. 1 the boat is shown in running conditions under full conditions while in fig. 2 is shown in lean conditions.

The load-bearing pantographs (2) have at their upper ends two floatation caissons (15) which can be filled either with air to make them float or with water to make them sink and these caissons (15) are tied to the boats (1) by means of hydraulic and electromechanical quick couplings not forming part of the present invention.

When the service must be interrupted on days of exceptional floods, the boats must be removed from the river to be hospitalized in suitable basins sheltered from the flood; in this case the boats (1) are released from the buoyancy boxes (15) and by means of the thrusters (8) and the maneuvering rudders (9) they reach the protected basin.

The flotation caissons (15) are then flooded allowing the load-bearing pantographs (2) to lower onto the submerged rails (6) and then remain flattened on the bottom of the river waiting for the flood to pass.

When the service can be resumed, an appropriate remote control signal will open the compressed air tanks (14) located inside the buoyancy boxes (15) making the water flow out of these tanks (15) and making them immediately reappear on the surface; at this point the boats (1) will be able to leave the protected basin and, by means of the thrusters (8) and the maneuvering rudders (9), will each reach their operating position where they will hang up to the caissons (15) to resume service.

At the upper end of the bearing pantographs (2) there are drive pistons (5) that allow you to vary the attitude of the boat during the stroke thus varying, as needed, both the lift and the hydrodynamic resistance

Claims (1)

RIVER UNDERGROUND WITH BOUND GUIDE CLAIMS 1. constrained guide river underground made with planing hull boats (1) which are tied to motorized carriages (3) equipped with wheels (11) driven by submerged electric motors (10) which run on submerged rails (6) anchored on the bottom of the river with fixed supports (7) on which they can therefore give the boat accelerations and decelerations that are completely impossible with boats with fluid dynamic propulsion. 2. boat for river underground as in rev. 1 bound to floatation caissons (15) which can be flooded and then submerged in the event of a flood and can then re-emerge when full through compressed air contained in special tanks (14) 3. boat as in rev. 2 also equipped with a maneuvering propeller (8) and a maneuvering rudder (9) 4. boat as in rev. 2 which is driven by wheels (11) which are driven by submerged electric motors (10) and which run on submerged rails (6) 5. motorized trolleys (3) of a river boat as per rev. which are kept anchored to the submerged rails (6) by means of retaining wheels (13) which act on the lower part of the upper bulb of the rails (6) and therefore prevent the wheels (11) from derailing 6. motorized trolleys (3) of a river boat as per rev. which are kept anchored to the submerged rails (6) by means of retaining wheels (13) which act on the lower part of the upper bulb of the rails (6) and can therefore ensure the necessary wheel / rail adhesion by means of load jacks (17) 7. loading jack (17) which gives the correct load to the wheels (13) in such a way as to ensure the necessary adherence to the main wheels (11) 8. actuation pistons (5) of the bearing pantographs (2) which allow you to vary the attitude and therefore the hydrodynamic resistance and lift of the boat during travel
