Description

buoyant turbine

technical field

The utility model relates to a hydropower generating device, in particular to a buoyancy water turbine.

Background technique

my country is a big country rich in water resources, but in many remote areas or areas that require agricultural irrigation operations, there is often no electricity access due to the incomplete coverage of power grid construction, which restricts the development of the local economy. In addition, the installed capacity of water turbines used in existing hydropower stations is large, and the construction cost is high, which is not conducive to construction and use in areas with poor economic conditions.

Utility model content

The purpose of the utility model is to provide a buoyant water turbine, which has simple structure, low manufacturing cost, easy popularization, and is suitable for use in areas with various economic conditions.

The purpose of this utility model is achieved as follows: a buoyant water turbine, the water turbine includes a hub, water tanks are evenly distributed on the outer periphery of the hub, each water tank has a water inlet, the water inlet is arranged along the radial direction of the hub, The other end of the hub shaft is connected to the shaft of the water turbine, and a high-pressure gas nozzle connected to the air pump is set under the hub. The high-pressure gas nozzle is opposite to a water tank water inlet at the bottom of the hub. Limit switch device for water inlet position.

When the utility model is in use, the wheel hub is installed in the water so that the water tank on the top surface of the wheel hub is exposed to the water surface. Firstly, the air pump sprays high-pressure air into the water tank at the bottom of the hub, and the water in it is squeezed out to fill it with air, so that the hub is out of balance, so that it can rotate. When the water tank rotates to the top surface of the hub, the air in the water tank will be discharged, and the water tank will be filled with water again as the hub rotates. When the next water tank is close to the high-pressure air nozzle, the high-pressure air nozzle will repeat the above action to discharge the water in it. It comes out and is filled with air, and in this way, the water turbine can be continuously used to drive the water turbine to generate electricity or output kinetic energy to drive external mechanical equipment to work. The utility model has the advantages of simple structure, low manufacturing cost, little influence of local economic conditions, and is especially suitable for use in remote areas.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the main view structure schematic diagram of the utility model;

Fig. 2 is a side view structural diagram of the utility model.

Detailed ways

A buoyant water turbine, as shown in Figure 1 and Figure 2, the water turbine includes a hub 3, water tanks 2 are evenly distributed on the outer periphery of the hub 3, each water tank 2 has a water inlet 1, and the water inlet 1 is along the hub 3 radial arrangement. Said water tank 2 is cylindrical, and the axis of water tank 2 is parallel to the axis of wheel hub 3 . The other end of the hub shaft is connected to the rotating shaft of the water turbine 4, and a high-pressure gas nozzle 6 connected to the air pump 5 is arranged under the hub 3. The high-pressure gas nozzle 6 is opposite to a water tank water inlet at the bottom of the hub 3. A limit switch device 7 for positioning the position of the water inlet 1 is also provided.

Said limit switch device 7 is a proximity switch or a travel switch, and the position of the nozzle 1 is positioned by the limit switch device 7, so that the automatic operation of the utility model can be realized.

The other end of the 4 rotating shafts of the water turbine can be externally connected to mechanical equipment, such as a rice spring machine. The electric energy that water turbine 4 sends can drive electric equipment such as water pump, lamp to work.
