Description

Flowing water power station

Technical field:

The utility model relates to a flowing water type power station which utilizes natural flowing water to generate electricity.

Background technique:

With the development of the economy, the demand for electricity all over the world is increasing. Hydroelectric generators play an important role in the electricity supply due to their economical and environmentally friendly operation. The current hydroelectric power stations are all fixed structures, and the hydroelectric power generation equipment uses the water flow drop to make the water turbine obtain power and drive the generator to generate electricity. However, these power stations require certain topographical conditions to be built, and a large number of civil engineering works such as damming the rivers are required, which requires a long construction period and huge investment. my country is a country rich in hydropower resources. There are many rivers, lakes and seas, and the flow rate is relatively fast. However, this hydropower resource has not been fully utilized, resulting in a large amount of waste of water resources.

Utility model content:

The purpose of this utility model is to provide an economical and simple hydroelectric power generation equipment, specifically a flow-type power station, which can overcome the above-mentioned deficiencies in the prior art.

The purpose of this utility model is achieved through the following technical measures: a flow-type power station, which is composed of a floating body, a water turbine and a generator, and is characterized in that: the water turbine and the generator are installed on the floating body, and rotatable blades are installed in the water turbine The power output shaft of the turbine is connected to the low-speed generator through the shaft end gear and the V-belt.

The low-speed generator is installed on the bank of the river through a bracket, and the rotatable blade set inserted into the flowing water is connected with the generator through the power output shaft of the blade set.

Multiple water turbines are installed on both sides of the floating body.

The water turbine is arranged between two adjacent floating bodies, and the power output shafts of multiple water turbines are connected together to form a large-scale equipment for centralized hydropower generation. The blades of the water turbine can be widened and lengthened according to the requirements of use.

The utility model has the following advantages or positive effects:

Because the floating body is fixed on the flowing water surface, it is fixed on the coast with steel ropes, and the flowing water is used to generate electricity, so there is no need to build dikes and dams, and the water potential drop is not required, so it can be used on flowing rivers and lakes. Through the automatic take-off and landing speed regulation system of the turbine, it can meet the needs of power generation load changing at any time; the position of the generator can be moved arbitrarily along the river, or the generator can be installed along the river, and it is connected with the turbine inserted under the water surface. Compared with the existing hydroelectric power generation equipment, the invention saves time and labor, does not need to carry out a large number of civil engineering, and greatly saves time and money. Moreover, it is especially suitable for installation along rivers, and can achieve immediate results and obtain inexhaustible cheap electricity.

Fig. 2 is a schematic view along the direction A in Fig. 1 .

Fig. 3 is a schematic structural diagram of Embodiment 2 of the utility model.

Detailed ways:

Embodiment 1: As shown in Figures 1 to 2, the floating flowing water power station provided by the utility model mainly installs one or more stages of water turbines 5 and generators 1 on the floating hull 6, and the water turbines are fixed on the side of the hull. Place the floating hull on the surface of rivers and lakes, anchor against the current, and make it float in the flowing water or fix it on both sides of the river with steel ropes. If the river rises and falls, the hull will automatically adjust to maintain stable power generation. The blades 7 of the water turbine dive into the water from both sides of the floating hull, and are driven to rotate by the flowing water. The power obtained by the water wheel blades is transmitted to the shaft end of the generator 1 through the transmission belt 4, and the generator is driven to run and generate electricity. The bearing 3 and the clutch 2 installed at the two ends of the drive pulley are all available on the market or are easy to order parts and components. The bearing 3 can be a ball or roller bearing; the clutch 2 can be a side tooth clutch or an electromagnetic clutch.

Embodiment two: the flow-type power station as shown in Figure 3, the working principle is the same as embodiment one, a support is installed on the bank of the river, and the generator 1 is fixedly installed on the bank of the river through the support, and the blade 7 parts of the water turbine are submerged In the flowing water, the power output shaft of the blade is directly connected to the low-speed generator, which drives it to run and generate electricity.
