Description

Non-drop semi-submersible power generation boat

technical field

The utility model relates to a hydropower generating device.

Background technique

Conventional hydroelectric power generation requires a certain water level drop, and a dam must be built on the river to raise the water level and head. The upstream ice level is raised to form a reservoir, and the water in the reservoir is introduced into the factory building through the water pipe to generate electricity through the hydroelectric generator set. At present, the hydroelectric power generation with medium and high water head at home and abroad is almost depleted.

Contents of the invention

The purpose of the utility model is to provide a non-drop semi-submersible power generation ship that does not need to build a dam to raise the water level.

The utility model is completed by the following technical solutions:

The utility model relates to a non-drop semi-submersible power generating ship, which is composed of a movable hull, a water wheel mechanism, a gearbox and a generator. The water wheel mechanism, gearbox and generator are all installed in the hull. There is a ballast tank inside the hull, a windlass winch, a ventilation bend and a power control room on the deck, and signal lights on the top of the room. The water wheel mechanism includes a flow collecting cover and a flow guide tube. The flow collecting cover is bell-shaped and is arranged at the water inlet of the flow guide tube. The runner shaft, bearing and bearing seat are arranged in the flow guide tube, and the water turbine For the blade, the water turbine blade front end is provided with a water discharge cone, and the rear part of the draft pipe is provided with a main shaft conical chamber. The runner shaft is connected with the gearbox and the generator through the transmission main shaft. The main shaft, the gearbox and the generator are all located in the main shaft conical chamber.

The utility model has a non-drop semi-submersible power generation ship with a movable hull. Both the gearbox and the generator are installed in the hull. When the hull is fixed in the running water, the running water is used to drive the water wheel mechanism to run. Then through the gearbox to change the speed, it drives the generator to generate electricity.

The power generation ship of the utility model does not need to build barrages, does not occupy land, has less investment, and can achieve semi-submersible power generation. The hull can move its position according to the current situation and needs, can make full use of water conservancy resources, is easy to use, low in cost, and strong in applicability. It is most suitable for the development of small hydropower. The location can be moved freely along the river and can provide cheap electricity. The utility model also has the characteristics of simple structure, low cost, safety, reliability and high efficiency.
