Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the transportation of a cylindrical water turbine generator installed in a waterway, and in particular to a straight water turbine generator suitable for marine and river transport.
Regarding the method of transporting bokuma.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 54-16544, in conventional equipment, the main engine main body outer cover was divided into a water turbine casing and five stator cones due to land transportation restrictions, and then transported to the site and installed on one divided surface. The gasket is inserted into the gasket groove and is integrated into the glue-o assembly to prevent water leakage. However, with this method, it is necessary to disassemble the product at the time of shipment from the factory and reassemble it after delivery to the site, which requires a lot of man-hours and is uneconomical.In addition, there are problems with low safety such as water leakage due to deterioration of the packing etc. was there.

[Problems that the invention attempts to solve]

The annular chamber between the outer sheath of the water turbine generator and the concrete wall is used as a water channel, and the water turbine casing 11, stator 12 and hicone 1
3. It is formed by a water wheel runner 14 and the like. Is this cylindrical water turbine generator low? A design that has the advantage of high efficiency in terms of Pf difference, low head (about 4m to 15m)
Recently, as the trend toward effective use of water resources has increased, the application of this method has been expanded to include highly efficient cylindrical water turbines. However, as mentioned above, since cylindrical water turbine generators are installed in waterways, if water leaks from the connection part of the outer sheath, this water will enter the machine and cause damage to the rotor, stator coils, and core. , or a serious accident that damages the bearings and causes the generator to stop operating.

As a way to prevent this, as shown in Figure 3,
Gaskets] 5 are placed radially inside and outside the connection surface of the outer sheath to prevent water leakage. but.

There is also the possibility of water leakage due to deterioration of the packing, etc.
There is a lack of certainty regarding waterproofing.

An object of the present invention is to provide a transportation method for integrating the water turbine casing, stator, cone, etc. into an integral structure in order to prevent water leakage from the contact surfaces of the water turbine casing, stator, cone, etc.

[Means for solving problems]

The above purpose is to provide a power source above the integrally assembled cylindrical water turbine generator, connect it to a simple boat, and install a temporary drive source (at the end of one generator shaft).
This is achieved by attaching a hydraulic motor (hydraulic motor) and using this to rotate the water turbine runner in the opposite direction, thereby making the cylindrical water turbine generator itself movable using the thrust obtained.

[Effect]

The buoyancy of the integrally assembled cylindrical water turbine generator allows the simple boat to float easily, and the water turbine at the end of the shaft is powered by a temporary drive source attached to the shaft end of the starter, using the power supply provided on the boat. / Reverse the table. Due to this thrust, the cylindrical water wheel was used to propel the aircraft to its final installation point.

For this reason, the water turbine casing, which had a conventional split structure,
Stator, cone, etc. can be manufactured in one piece. That is, since there are no split connection surfaces, water leakage from these parts is eliminated.

〔Example〕

Two embodiments of the present invention will be described below with reference to FIG.

A cylindrical stay 7f is installed above the integrally assembled nine-cylindrical water turbine generator 1.
A simple boat 2 is attached to the boat 2, and the boat 2 is equipped with a cabin 3 for marine and river operation, an engine generator 4 to be delivered to a power plant for emergency use, and a hydrodynamic pump 5f. In addition, a hydraulic motor 6 for driving is attached to the shaft end of the cylindrical generator,
Using pressure oil from the hydraulic pump on the ship, the water turbine runner 1
Propulsive force can be obtained by reversing 4. Therefore, without disassembling the factory-assembled cylindrical generator 1,
It can be transported as it is by sea or river to the final installation location.

According to this embodiment, the cylindrical generator, which conventionally had a split structure due to transportation restrictions, can be made into an integrated structure, and there is an effect of preventing water leakage from the split connection. Furthermore, since it can be assembled and transported at the factory, the on-site installation period can be shortened.

15 in the figure is Patsukin.

〔Effect of the invention〕

According to the present invention, since the cylindrical water turbine generator can be manufactured as an integral structure, there is no need for a one-piece joint, and water leakage potential can be eliminated.
