Full Text | FIELD.. QF This invention relates to a hydro-turbines power generator for generating electric power employing the potential energy contained in a height of water. KNOWN ART Presently, conventional hydro-turbine generators are not available in submergible or submersible construction. Thus, the known generators are normally installed indoors in a covered room, so that no water is allowed to come in contact with the electric generator, which adds to cost of the installation. It requires wore space also. In the hilly slopes, enough -flat sp«c» ia not easily available and therefore the turbine units can be installed in much -fewer locations and energy abvailable from most of the falls goes unutilised and thus wasted. Also quite often the turbine sites have to be far away from the falls and increasing the length of pipe penetocke, thus considerable amount of energy is lost in pipe friction or alternatively, the pipe diameter has to be increased. OBJECTS oF INVENTION A primary object of this invention is to propose a chydro-turbine generator which is submergible or submersible. Another object of this invention is to propose an improved, hydro-turbine generator which can be employed nearer to the waterfall or even on the water stream. A further object of this present invention is to propose an improved hydro-turbine generator having a construction such that no water or moist air can enter the inside of the generator and thus prevent it from damage by moisture even when installed to operate in the open outdoor or in a flowing stream without any external protection from falling water or moist air. Still another object of this invention is to propose an improved hydro-turbine generator and wherein the wire leads carrying electric power from the generator are » properly sealed at exit from the generator, BO that no moisture can seep into the generator machine along the wire leads. Yet another object of this invention is to propose an improved hydro turbine generator and wherein the electric control panel can be located remote from the generator at a convenient covered place. BRIEF DESCRIPTION OF INVENTION According to this invention there is provided an improved hydro-turbine power generator for generating electric power by employing the potential energy contained in a height of water comprising: (i) a generator casing having electric generator disposed therein, the output terminals of said generator connected to a control panel for employing electrical power to a load through said control panel, (ii) an oil reservoir casing having an oil reservoir below the said electric generator and held to the casing of said electric generator, (iii) a turbine head casing disposed below of and held to said oil reservoir casing and having an inlit adopted to be connected to water feedstock pipe, (iv) a turbine casing below of and held to said turbine head casing, a runner disposed within said turbine casing for causing a rotation of the turbine shaft upon water impinging on said runner, (v) said runner shaft coupled to the generator shaft through a coupling, characterised in that a mechanical rotary seal provided on said shaft; below of said oil reservoir and an electrical probe. DESCRIPTION OF INVENTION WITH REFERENCE TO DRAWINGS Further objects and advantages of this invention Uphill be more apparent from the accompanying drawings and wherein: Fig.l snows a scheinatic c view of the generator in accordance with one embodiment of the i nvent ion Fig.2 shows a schematic view o-f the generator in a accordance with another view. The generator (A) o-f the present invention has a construction such as to prevent entry of moisture or water into the interior o-f the generator to damage the electrical insulation. The shaft (l) of the generator is supported and rotates between suitable ball bearings (2&3) at the top and bottom of the rotor (16), as shown in Fig.1, The shaft extends at the bottom through the generator cover shield into the oi1-chamber (8>. A mechanical frictionlesB rotary seal is incorporated below the lower ball-bearing cover shield . This rotary seal operates in an oil chamber (8). In an alternative construction, as shown in Fig.2, the generator shaft extends at the bottom from the oil-chamber into the turbine-head A mechanical rotary seal (9) operates below the oil -chamber (8) , which protects the water in turbine-head (D) from entering the oil-chamber (8). Just in case, if the seal (9) starts leaking, water in trickles would enter the oil -chamber and oil floats on the water in the oii-chamer .An electrical probe (10) in the oil chamber (8) instantally sends an electrical signal through connecting wire The shaft. (1) further extends into the volute chamber and holds the runner (19) at (20). Another mechanical rotary seal (9) operates below the oil-chamber (8) . which protects the water in the turbine area -from entering the oil-chamber (8). The rotary seals are normally expected to work st at isf actor ily for long periods. However, just in case, after its full running life, if the seal (9) starts leaking, water in trickles would enter the oil-chamber (8) . An electrical probe instantly sends an electrical signal through a multi-core connecting cable (11) to the control panel The top and bottom generator shields which hold the top and bottom ball bearings respectively, are also properly sealed at the joints with the generatos body (14) and securely bulted. Thus, the moisture is not allowed to enter the generator through these joints also. The generator A, the oil-chamber and the turbine are all integrally bolted together to ffiaintain the alignment of the generator and turbine to ensure smooth continuous operation o-f the whole unit. |
