A turbine according to the present invention is characterized in that a plurality of blades 2 having a curved cross section are fixed to a blade shaft 1, and an injection nozzle 3 is installed inside a curved surface of the blade 2. In the above, a high-temperature and high-pressure steam is generated by the gas combustion means 5 and the water supply nozzle 6 installed in the combustion chamber 4 inside the blade shaft, and the steam is injected from the injection nozzle 3 to rotate the blade 2, and the rotational force is applied to the outside. This is a turbine characterized by taking out as an output. [Claim 1] [Claim 2] is a turbine for cleaning the inner wall of a pipe such as a sewer pipe 8 or a manhole, utilizing the features of the present turbine. In a turbine, wherein the injection nozzle 3 is installed inside the curved surface of the blade 2 and fixed, a cleaning member 7 fixed to the blade shaft 1 and elastically contacting a pipe inner wall having a diameter larger than the rotation diameter of the blade is provided. Having.

[0005]

The turbine ignites and burns a mixed gas or the like supplied from the outside inside the blade shaft 1 and further injects water into the combustion chamber 4 by the water supply nozzle 6 to generate steam. The high-temperature and high-pressure steam is supplied to the impeller 2 by the injection nozzle 3.
And the blade 2 is rotated. [Claim 1] In the present turbine, the blade 2 is rotated by injection of steam or the like from the injection nozzle 3, and at the same time, high-temperature steam is blown from the tip of the blade to the outer periphery of the blade. Therefore, the turbine can be cleaned by rotating the brush while spraying steam by causing the cleaning member to elastically contact the inner wall of the sewer pipe or the like and running the vehicle on a vehicle or the like. [Claim 2]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an explanatory diagram of the operation of the turbine. [Figure 2]
It is an II partial sectional view. This turbine has a configuration in which the blade shaft 1 is rotatably supported by a fixed shaft 9 as shown in FIG. 2 and a method of supporting the outer periphery of the blade shaft (“Saponius type” by the present applicant). Turbine) (Fig. 2), and the present invention is applied to both. In the embodiment, an example in which the combustion chamber is supported by a fixed shaft will be described. However, in a method of supporting the outer periphery of the blade shaft, the combustion chamber is formed inside the blade shaft. A hollow combustion chamber 4 is formed inside the fixed shaft 9,
The combustion means 5 and the water supply nozzle 6 are inserted into the combustion chamber 4 from the end of the fixed shaft 9. The combustion means 5 includes a combination of a fuel nozzle and a compressed air supply nozzle, or a mixed gas nozzle and a spark plug. In order to obtain a uniform combustion effect, the periphery of the combustion means 5 may be covered with a ceramic mesh cover 10. When water is injected from a water supply nozzle 6 into the combustion chamber 4 in which the fuel is ignited and a high-temperature and high-pressure combustion gas is generated, the water is vaporized into steam and expands to further increase the pressure in the combustion chamber. 11 and the like, a plurality of blades are fixed on the same concentric circumference of the blade shaft 1, the blade 2 has a curved cross section, and the injection nozzle is fixed to a lower portion inside the curved surface of the blade. Fixed shaft 9
Of the combustion chamber 4, which forms a part of the combustion chamber 4, is provided with a number of ventilation holes, which communicates with the inside of the blade shaft. The combustion gas passes through the combustion gas path 12, and is injected from the injection nozzle to the inside of the blade.
Rotate the wings. As shown in FIG. 2, the passage of the combustion gas may be secured by making the connection arm 11 hollow. The output of the turbine can be taken out by fixing the pulley 13 or the like to the blade shaft 1. [Claim 1] [Claim 2] is an example in which the present turbine is applied to a cleaning device for an inner wall such as a sewage pipe 8, and FIG. The cleaning member 7 that rotates together with the blade is installed at a position larger in diameter than the rotation diameter of the blade, and is in elastic contact with the inner wall of the drain pipe 8. The high-pressure steam in the combustion chamber 4 is injected from the injection nozzle 3 to rotate the blades, and the steam is blown to the pipe wall by the remaining force to exert a cleaning action. The pipe wall is wet with hot steam, and the cleaning effect is expected to be improved by the cleaning member 7 that sweeps the inner wall of the sewer pipe 8. When cleaning turbines are used in sewer pipes, etc., they are usually mounted on vehicles and used.However, in order to offset the sweep load on the vehicle caused by unidirectional rotation of the turbine, the right-rotating turbine and the left-rotating turbine are used. A method in which a turbine is used by connecting it back and forth is also effective.
Various cleaning members such as sponges and brushes are selected depending on the pipe to be cleaned.

[0007]

The present turbine has a very simple structure, such as having a combustion means in the turbine, and eliminating the need for a boiler by vaporizing water in the turbine. It opens the way to the vapor engine. It is also useful as a multi-dwelling house or cogeneration for home use. The cleaning turbine according to the present invention includes:
The steam, which is the driving source, is effectively used as cleaning means, and the functions required for cleaning are configured very compactly.
