Description

The invention relates to collapsible floating structures with little draft and can be used for independent movement of a car through water.

Movement of a car through water, including in shallow water areas, is possible with the help of a floating structure with a slight draft, such as a pontoon, catamaran, raft. Of the known floating structures closest to the claimed device, floating dachas (PD) should be distinguished, which are a small-sitting catamaran type pontoon in which water movement is carried out using outboard or stationary boat motors, or by towing. For transportation by land, floating cottages are converted into a car trailer. Description of floating cottages, both domestic and foreign, is given in the magazines "Boats and Yachts". See, for example, E.A. Poting “Ships-dachas”, No. 1, 1963, pp. 92-95, 4 silt; a brief description of the PD of the American company "Keiot", No. 1, 1977, s.19-20, 3 il; PD "Alyonushka", the association "Rhythm", No. 1.1972, p. 10, and No. 1.1977, pp. 12-14, 1 ill .; high-speed PD - catamaran, No. 6, 1977 p. 45-46, 2 ill.

The closest analogue of the claimed invention can be considered high-speed PD - Catamaran, see the magazine "Boats and Yachts". No. 6, 1977, S. 45-46, 2 ill., Which is accepted as a prototype. The prototype has two floats welded from 1.5 mm steel. The size of each float is L = 7.5 m, _Bk = 0.5 m, draft T = 0.12 m. Movement through the water is carried out using the outboard motor "Moscow-12.5". Gross weight - 800 kg. The prototype does not allow for independent movement of the car through the water.

The aim of the invention is the creation of a collapsible pontoon-catamaran with low draft, convertible into a trailer when driving by land, which when assembled allows the car to independently use its own mass to push itself together with the pontoon from the shore into the water and move through the water for account of its engine, controlling the movement from the cab, as well as when driving on land.

The inventive collapsible pontoon catamaran for independent movement on the water of a front-wheel drive vehicle is transported when traveling by land in the form of a trailer. It contains assembled from sections flat floats. They are connected by beams and have. wheel niches mounted on floats and folding bump stops for entry. departure, placement and fastening of the car on the pontoon while swimming. A distinctive part is the addition of rotary propellers driven by front wheels, which are installed in rotary tool holders, rigidly connected to the propellers drive, consisting of a drum rotated by the vehicle wheel. which is connected to the propeller via a gearbox.

Figure 1 presents a drawing of a General view of the pontoon for front-wheel drive passenger car.

The pontoon has two flat floats. Each float is assembled from four sections 1. The floats are connected in a catamaran by three beams 2. On the floats are wheel niches 3 corresponding to the width of the wheels. The floats also have stops 4 under the front and rear bumpers of the car. The trailer wheels are placed on the stops and serve as a buffer when pushing the pontoon into the water. In the wheel arches 3 of the pontoon intended for a front-wheel drive vehicle, a cutout has been made at the location of the front wheels, in which lodges of wheels are installed as a single structural unit, together with drums, gearboxes and propellers. A rectangular cup 5 serves as a lodgment. A shaft 6 is placed in the center of the bottom of the cup for rotation around a vertical axis. The float section, on which the lodgement is placed, has a socket for installing this shaft. The upper part of the glass is equipped with passive rollers 7. Adhering to the wheel, they fix its position, allowing the wheel to rotate freely. A drum 8 is mounted on bearings in the middle part of the cup. The drum axis exits the cup in the form of a shaft from the outside. This shaft is connected to the gearbox, which has two gear conical pairs 9. The output shaft 10 of the gearbox serves as a propeller. A propeller screw, closed by a nozzle 11, is fixed on it. The gearbox is mounted on the outer side wall of the cup and can have two positions: working, in which the screw is lowered into water, and the duty, when the screw is raised from the water. The drum has a stopper, which is used when the car enters and leaves the pontoon to prevent slipping. The structural unit - lodgement, drum, gearbox, propeller, is installed in the shaft socket 6 of the float section during assembly. The sections of the floats on which the lodgements are installed have cutouts through which the propellers can be lifted out of the water or lowered into the water.

The device operates as follows. The car, along with a towed trailer, figure 3, drives up to the shore of the reservoir. Of the parts included in the trailer, a pontoon is assembled. Assembly is carried out so that the bow of the pontoon would be in the water. Before entering the car, the pontoon must be brought to its original position. Namely, the emphasis on the front bumper is raised and fixed, the emphasis on the rear bumper is lowered, the screws are lifted out of the water, the drums are mounted on the stopper. A car from the shore on wheel niches drives into a pontoon. When the front bumper is in contact with the focus, due to the impulse of the body, the pontoon collides with the car in the water. If necessary, this operation can be repeated. After the pontoon with the car is afloat, it is necessary to raise and fix the emphasis under the rear bumper, remove the stopper from the drums and lower the screws into the water. Then you can sit in the car and continue driving on water, as well as on land. In this case, the front wheels transmit rotation to the drums and from them, through gears, to the propellers. The direction of movement is determined by the position of the steering wheel of the car, which, thanks to the front wheels, sets the direction of the axles of the propellers. Mooring a pontoon to the coast is possible both with the bow and stern. The car is driven ashore, the pontoon is disassembled and assembled into a car trailer in the reverse order.

The inventive collapsible pontoon catamaran for independent movement on the water of a rear-wheel drive vehicle is transported when traveling by land in the form of a trailer. It contains assembled from sections flat floats. They are connected by beams and have wheel niches mounted on the floats and folding stops for entry bumpers. departure, placement and fastening of the car on the pontoon while swimming. A distinctive part is the addition of paddle wheels driven by the front wheels of the car and propellers driven by the rear wheels of the car. In this case, the front wheels are mounted in swivel lodges, rigidly connected with paddle rudders. The rear wheels are mounted in fixed lodgements with a propeller drive, consisting of a drum rotated by a car wheel, which is connected to the propeller through a gearbox.

Figure 2 presents a drawing of a General view of the pontoon for rear-wheel drive passenger car.

The lodgements for the front and rear wheels in figure 2 are indicated by the numbers 1 and 2. Each lodgement is installed in the cutout of the wheel niche. Lodgements of the front wheels are made rotatable around a vertical axis, the same as in the pontoon for a front-wheel drive car. The paddle wheels, indicated by the number 3, are fixed on the outer wall of the glasses of these lodges. Mounting the rudders provides for two of their positions - one at which the rudders are lowered into the water, and the second, at which the rudders are lifted out of the water. The sections of the floats on which these lodgements are installed have a cutout through which the rudders can be raised or lowered into the water. The lodges of the rear wheels together with the drive and the propeller are made in the same way as in the pontoon for a front-wheel drive car, except for the possibility of turning around a vertical axis. The sections of the floats on which these units are mounted have a cutout through which the screws can be raised or lowered into the water.

When operating the pontoon, an operation to raise and lower the steering wheel is added. The rest is the same as a front-wheel drive car.

Figure 3 presents the disassembled pontoon, arranged in the form of a trailer for towing a car when driving on land.

The claimed pontoon catamaran allows a production car to move independently on the water without any alteration. At the same time, traffic control comes from the cab, just as when driving on land. To launch it, the car pushes itself on a pontoon into the water. After approaching the shore, the car drives off the pontoon to land. When traveling by land, the pontoon is transported like a trailer. In the parking lot, the pontoon can be deployed in the form of a tent house. To overcome difficult areas, the pontoon can be used as wheel linings.
