Abstract

FIELD: bridges construction.

SUBSTANCE: invention relates to the construction of bridges and can be used to generate electricity. A horizontal shaft with blades is installed in the projection of the support and the rack. An electric generator is attached to the support. The support is hinged to the gate. The door has a bracket at the top, a hermetic container filled with air is attached to it at the bottom. A winch is located on the ledge. There is also a shaft on the stand. When the leaf is leaning against the rack, then almost all the water presses on the blades of the shaft. The pinion rotates the pinion quickly, allowing the generator to generate high power. When it is necessary to pass the vessel, the voltage is applied to the winches. The winch drum, rotating, winds the rope. The leaf moves away from the rack and leans against the shaft.

EFFECT: bridge of the proposed design generates high power electricity.

Description

The invention relates to the construction of bridges and can be used to generate electricity.

There is a known bridge consisting of superstructures located on supports in the projection of the support of which is installed at one end, having blades, some of which are located in the water, a horizontal shaft, the second end of which is installed in a rack on which a gear is fixed in contact with a gear fixed on the shaft electric generator (patent RU 2611643).

However, this bridge generates low power electricity, as the weak flow of water below it slowly rotates the blades of the shaft.

The technical result of the invention is the generation of high-power electricity by the bridge by increasing the flow of water under it.

The specified technical result is achieved by the fact that the bridge consists of spans located on supports, in the projection of the support of which there is one end with blades, some of which are located in the water, a horizontal shaft, the second end of which is installed in a rack, on which a gear is fixed in contact with gear, fixed on the shaft of the generator, while the second support is connected by a hinge to the gate, which has a sealed container at the bottom, filled with air, and at the top, a bracket for which the first winch is engaged, located on the protrusion of the second support, and the second winch located on the rack.

Figure 4 shows a bridge closed by a gate, sectional top view.

Figure 5 shows a part of the bridge, longitudinal section.

Figure 6 shows a part of the bridge, top view, section.

The bridge has the following design. Spans with sidewalks 2 and railings 3 are located on supports 4 and 5. Support 4 has projections 6 and 7. A horizontal shaft 9 is installed in the projection 6 and post 8 on bearings 9. Blades are attached to shaft 9 10. Gear 11 is fixed to shaft 9 An electric generator 12 is attached to the support 4. The shaft 13 of the generator 12 is mounted on a bearing in the projection 7. A gear 14 is fixed on the shaft 13, which is in contact with the gear 11. The electric generator is connected by wires 15 to a power line. The second support 5 has a protrusion 16. The support 5 is connected by hinges 17 to the gate 18. The gate 18 has a bracket 19 at the top. At the bottom to the opening 18 is attached an air-filled hermetic container 20 made of an elastic material. On the ledge 16 there is a winch 21, the cable 22 of which is hooked on the bracket 19. On the rack 8 there is a winch 23, the cable 24 of which is hooked on the bracket 19.

The bridge generates electricity as follows. Water flowing near the support 4 pushes the blade 10. Since the opposite blade 10 is in the air and the water pressure does not act on it, the shaft 9 constantly rotates in the bearings of the projection 6 and the rack 8. The gear 11 fixed on the shaft 9 rotates the gear 14 The shaft 13 rotates the armature of the electric generator 12. A voltage is generated on the stator of the electric generator, which is fed through the wires 15 to the power transmission line. When the gate 18 is leaning against the post 8, the water flow between the post 5 and the post 8 is blocked. All the water flows between the rack 8 and the support 4. It presses with force on the blades 10. The shaft 9 rotates rapidly. Gear 11 quickly rotates gear 14 and shaft 13. Electric generator 12 generates high power electricity. When it is necessary to skip the vessel, the voltage is applied to the winches 21 and 23. The winch drum 21, rotating, winds the cable 22. At the same time, the winch drum 23, rotating, unwinds the cable 24, moves away from the rack 8 and leans against the ledge 16. The winch drum 23 continues to rotate , unwinding the rope 24. The rope 24 falls to the bottom, without interfering with the passage of the vessel. After the passage of the vessel, the reverse polarity voltage is applied to the winches 21 and 23. The winch drum 23 rotates, winding the cable 24. The winch drum 21 rotates, unwinding the cable 22. The gate 18 departs from the projection 16 and leans against the post 8. The container 20 filled with air supports the gate on water, facilitating its movement between the ledge 16 and the post 8. During the passage of the vessel under the bridge, the electric generator generates low power electricity, since a small pressure of water is supplied to the blades 10 of the shaft 9. However, the ships pass under the bridge for a short period of time. The rest of the time, the generator generates high power electricity.

The use of the bridge of the proposed design will provide the following technical and economic effect. Thus, a bridge of a known design generates low-power electricity. The bridge of the proposed design generates high power electricity. Therefore, the cost of its construction will pay off faster.
