Description

SYSTEM FOR PREVENTING OVERFLOWS

I)AREA OF TECHNIC THAT THIS INVENTION BELONGS TO

This invention belongs to dams on rivers and streams,equiped with water gates for regulating water flow and to accumulations.

2)TECHNICAL PROBLEM

Raising of level of rivers and streams,especially in spring and autumn,after snow thawing and during longlasting rainfalls,causes flooding of settlements,crops, transport lines etc.Overflows causes great demages and sometimes loses of lives.

3)STATE OF TECHNIC

Solution of this problem,until now, was mostly tried to be solved by making levees on rivers and streams banks.On that way was tried to prevent water uotflow.Often, that is not successful and water goes over levees or destroy it, causing bigger or smaller demages.

4)DESCRIPTION OF ESSENCE OF THE INVENTION

Primary aim of the invention is preventing overflows, that becomes by uotfiowing of water from rivers and streams.Preventing of river overflow is achived by diverting river or stream from their watercourse in earlier planned area.

Secondary aim of the invention is using diverted water from river or stream for producing electricity,irrigation,tourism,fish growing,accumulation of drinking water or water for industry. System for Preventing Overflows,according to this invention,contains river or stream, that should be diverted,partly or completely,from their watercourse,using in that purpose dam equiped with water gates 3,12,35,67,68 that glide along guides 4,13,36,37,38,69,70,118,119,moved by electromotor 101 and coupling 99 and speed reducer 98. Water gates regulate water level in river or stream 1 and,if needed,diverts it in accumulation S which is located between hills or mountains 6 and 7 or in a digged hole in ground in which is located accumualtion 14,that on its end has dam 8,15,28,53 equiped with water gate 120,121,122,123 or turbine for producing electrcity,if needed,as well as canals for watering 33 if riveer or stream diverts in canals. If river is navigable for ships and boats dam 64 is used, whose parts 65 and 66 can be opened for passing ships and boats,as well as dam 19 that turnes to support 24 and on that way completely opens way for ships and boats and it can be used also for that purpose besides for purposes mentioned above.Parts 65 and 66 are opened using electro-motor 63.coupling 62 and speed reducer 60 which is connected to cable drum 61 on which cables 57 are coiled that go over disc 56,and cables are with its other end fixed to fasteners 58 that are located on parts 65 and 66.Electro-motor 63,coupling 62,speed reducer 60 and cable drum 61 are located in cabin 55.Discs 56 are fixed to frames 59 which are fastened to dam 64.

Water gates 68 slide through guides 69,and water gates 67 and 73 through guides 70,72,118,119 and guide 72 is fixed to water gate 73 by welding or by other proper way. Parts 65 and 66 are fastened to axis 103 on which are pillow-block bearings 71 set,which are by screws 104 fixed to U profiles 105 and 106, which are fixed by screws 108,that are passing through spacer 107.

U profies abut on pillar 109.

Guides 118 and 119 are in shape of dovetail and through them are passing supports 111 on which is fixed frame 113 with screws 112.

Frame 113 is fixed by welding or on some other proper way to plate 115 over lever 117 and plate 115 is fixed to plate 116 with screws 114.Plate 116 is a part of parts 65 and 66. Dam 19 is fixed to roof 76 of cabin 22,by welding or by some other proper way.Roof 76 contains shields 77 against entering dust and moisture.To roof 76 is fixed, by screws or on some other proper way .cover plate 74, on which is welded axis 75,which abuts on barrel-shaped roler bearing 84 and on wheels 8O.Barrel-shaped roler bearing 84 is located in housing 81, which has sealing 95,and it is fixed by screws 83 to support 85,which is a part of support 86.To roof 76 is fixed by screws 125,inside toothed wheel 76, which is meshed with toothed wheel 87 driven by electromotor 90 over coupling 89 and speed reducer 88.Electro-motor 90 is located on stand 91, which is fixed by screws 92 to support 86.Speed reducer 88 is fixed by screws 94 to stand 93,which is welded ,or on some other proper way fixed, to housing 79.

Dam 19 has balance weight 20 which is with belts 21 fastened to lattice work or some other proper dam structure. With its other end dam 19 abuts on supports 24,25,26 and 126,in which is located hydraulic cylinder 42 with piston rod 40,that passes through hole in plate 127.Hydraulic cylinder is driven by electro-motor 47, belt pulley 45,pump 46 and oil goes through tubes to cylinder over valve 44.OiI is in tank 43.

If it is necessary,for diverting river or stream walls 17,34 can be used.

System for preventing overflows works as follows:On river or stream is built dam 2,11,19,64 that should divert river or stream in a prior prepared area.On that way extra water from river or stream cannot pass to area for which we do not want to be flooded. That extra water makes accumulation 5,14,27,54.Above mentioned accumulation can be used for producing electricity, watering,tourism, fish growing,drinking water or technological water.

Accumulation could be filled with water when does not exist danger of overflow,in purposes mentioned in the last sentence.

Water gates 3,12,35,37,67,68 are used for diverting water and regulating water level in river or stream and regulating quantity of water that will be diverted in accumulation. Water gates glides along guides 4,13,36,37,38,118,119,moved by electro-motor 101, coupling 99, speed reducer 98 and toothed wheel 100 which is in mesh with rack 102 that is, by welding or on some other proper way, fixed for water gate.

At the end of accumulation there is dam 15,8,28,53, which purpose is making accumulation, that is preventing that extra water from river or stream, through channel 9, 16,31 ,52 returns in river or stream,causing flooding.If the area, located downriver from the area that we want to protect from flooding, is not important to be protected from overflow,than dam 8,15,28,53 is not necessary, as well as accumulation 5,14,27,54, and on that way costs of "System for Preventing Overflows" can be decreased, except if we want to achieve secondary aim of this invention. Water gates 120, 121 , 122, 123 are used for regulation water level in accumulation, as well as for regulation quantity of water that returns into river or stream flow, and they are moved on the same way as water gates 3,12,35,110,67,68.

If river is navigable, then dam 64 is used,which has movable parts 65 and 66 that rotates around axis 103, which stands on slide bearings 71, that are fixed on U profiles by screws 104. U profiles 105 and 106 are fixed by screws 108, and passes through spacer 107. Opening and closing of movable parts 65 and 66 is done by electro-motor 63,coupling 62,speed reducer 60 and cable drum 61 on which cable 57 winds, which is with its other end fixed for fasteners 58, that are on movable parts 65 and 66.

Water gates 67 and 75 have, besides guides that have other water gates, the additional guides 118 and 119 in shape of dovetail, which purpose is to hold water gates when they are lifted. When ships or boats need to pass,movable parts rotate and on that way enable their shipping. For navigable rivers can be also used dam 19 which with its turning to support 24 enables shipping.Dam 19 rotate around axis 75 that abuts on axial barrel-shaped roller bearing 84 and on wheels 80 and it is moved by electro-motor 90 connected to coupling 89,speed reducer 88 and a pair of toothed wheels 87 and 78 that has internal teeth.Sealing 95,set in housing 81, stops entering dust into bearing and leaking grease from it.

Hydraulic cylinder 42, whose piston rod passes through hole in plate 127 enables fixing of dam 19.Each of supports 24,25,26 and 126 have built-in hydraulic cylynders 42,whose piston rod is moved by electro-motor 47,over belt pulley 45 and pump 46.Purpose of door 41 is to enter in the plant for its maintenance.

Dam 19 can be used in purpose of directing water in different areas and for different purposes mentioned in secondary aims of the invention.Directing water is done by rotating dam to different supports 24,25,26 or 126.
