The retractable Electrical power has become an essential part of our part of the bridge would be designed through a daily lives and when it is interrupted or not available, mechanism that would support and maintain the then the ability to do our jobs or to be able to balance and position of the retractable part (sliding function in a normal manner will become an mechanism). The bridge structure would require a imposition to our daily routine. The electricity stable and strong structure to maintain its balance and requirement of the world is increasing at an alarming stable during retraction of the bridge. The material rate due to industrial growth, increased and extensive usage must be should not have any vibration effect use of electrical gadgets so we can increase the usage which would be dangerous if the bridge would be of the best alternative source nothing but An easily affected by the vibration of the water and the air. efficiently natural source of energy from sunlight as A movable bridge is a bridge that moves to allow ”solar energy’. This paper presents the automation of passage (usually) for boats or barges. An advantage of movable bridges. Most movable bridges rely on making bridges moveable is the lower cost, due to the electrical power to control and operate the absence of high piers and long approaches. The mechanism that causes the bridge to move. So in this principal disadvantage is that the traffic on the bridge regard an automated movable bridge is designed, but must be halted when it is opened for passages. For the required energy for the movable bridge is not seldom-used railroad bridges over busy channels, the taken from the conventional source but is generated bridge may be left open and then closed for train through wind and solar energy which is an passages. For small bridges, bridge movement may be innovative trend of technology for controlling the enabled without the need for an engine. Some bridges movable bridges. Usually, photovoltaic (PV) cells are operated by the users, especially those with a boat, contained in solar panels convert the sun's energy others by a bridge man (or bridge tender); a few directly into electric energy. remotely using video-cameras and loudspeakers. Generally, the bridges are powered by electric motors, Key words: Solar panel, DC motors, 89C51 whether operating winches, gearing, or hydraulic Microcontroller, IR sensors, Wind turbine pistons. While moveable bridges in their entirety may be quite long, the length of the moveable portion is I. INTRODUCTION: restricted by engineering and cost considerations to a The main idea of the proposed model is to build a few hundred feet. There are often traffic lights for the movable bridge that would automatically retract to road and water traffic, and moving barriers for the road give way for the ship to pass. The bridge will have a traffic. portion of the bridge, which would be in the center of the bridge that would automatically retract once it gets Types of movable bridges signal from the ships which is wished to pass through Drawbridge (British English definition) – the it. The idea of retraction was to be creative and bridge deck is hinged on one end Page 1727 Bascule bridge – a drawbridge hinged on pins with this would also have encouraged their use. Vertical lift a counterweight to facilitate raising bridges were also built, but they were more expensive o Rolling bascule bridge – an unhinged and had limited clearance so were unsuitable for drawbridge lifted by the rolling of a docks. In the first half of the nineteenth century, cast large gear segment along a horizontal iron was used for most large swing bridges, something rack of a compromise because of its brittle nature. Outside girders were often damaged by glancing blows from Folding bridge – a drawbridge with multiple ships passing through the bridge passage. The width of sections that collapse together horizontally passage was also restricted to around 40 feet, too Curling bridge – a drawbridge with multiple narrow for the paddle boats which came into use in the sections that curl vertically mid-nineteenth century. From this time iron, and later Vertical-lift bridge – the bridge deck is lifted by steel, lattice and plate swing bridges were introduced. counterweighted cables mounted on towers Table bridge – a lift bridge with the lifting They were still vulnerable to damage from passing mechanism mounted underneath it ships and many were subsequently replaced by rolling bascule bridges. As the deck lifted it moved away from Retractable bridge (Thrust bridge) – the bridge the edge of the passage so was unlikely to be damaged deck is retracted to one side by a passing ship. Other types of movable bridge were Submersible bridge – also called a ducking bridge, developed, but they tended to be used in locations the bridge deck is lowered down into the water where there were specific problems, such as a poor Tilt bridge – the bridge deck, which is curved and foundation or restricted space. The range of movable pivoted at each end, is lifted at an angle bridges is extensive, so some limitation is necessary to Swing bridge – the bridge deck rotates around a make the compilation of a list manageable. For this fixed point, usually at the centre, but may resemble reason, most bridges where the passage is less than 18 a gate in its operation feet will be excluded. These tend to be canal bridges, and are probably already quite well documented. A Transporter bridge – a structure high above carries few may be included to give an indication of their type a suspended, ferry-like structure and survival. This will also restrict the list to metal Jet bridge – a passenger bridge to an airplane. One bridges, though the earliest swing bridges were built end is mobile with height, yaw, and tilt from timber, and an example could be included for adjustments on the outboard end completeness. Movable bridges are only necessary on navigable waters, where wooden Dutch-style draw bridges were used prior to the introduction of swing bridges (possibly c 1650). When draw bridges were open it was difficult for the bridge deck to clear the bridge's navigable passage completely, and this was probably the main reason for the development of the swing bridge. The increasing size of bridges in the early nineteenth century, to cope with both increases in road traffic and the size of ships, meant that greater force was needed for operating an opening bridge.

Limit switches cooling through solar architecture, potable water via are used and they are arranged at various points of distillation and disinfection, day lighting, solar hot mechanical structure to identify the position of the water, solar cooking, and high temperature process moving bridge. It's a new method that is more heat for industrial purposes. To harvest the solar predictable, more reliable, more product friendly and energy, the most common way is to use solar panels. less maintenance prone than conventional bridges. The mechanical transmission section designed with Solar technologies are broadly characterized as either lubricated bearing type sliding channels or gear drive passive solar or active solar depending on the way they mechanisms that move the bridge smoothly. capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels The entire system is designed to operate at 12 V DC; and solar thermal collectors to harness the energy. the required power source is derived from non conventional sources of energy i.e., wind and the solar Passive solar techniques include orienting a building to power. The idea of using wind and solar energy is to the Sun, selecting materials with favorable thermal utilize non–conventional energy resources effectively.
