The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example 1

As shown in fig. 1-3, the present embodiment provides a pneumatic wave power generation unit, which comprises a gas chamber 1, a turbine 2 and a power generation device 3, wherein the gas chamber 1 is a semi-closed structure with an open bottom, the gas chamber 1 intersects with the sea level, generally, the bottom of the gas chamber 1 is slightly lower than the sea level, a certain gas space is left in the gas chamber 1, when there is a wave, the space formed by the sea level and the gas chamber 1 is compressed or expanded to generate a gas pressure difference, thereby affecting the discharge and suction of the gas.

The impeller 2 is arranged outside the air chamber 1, the impeller 2 comprises a shell 21 and an impeller 22 positioned in the shell 21, the shell 21 is communicated with the air chamber 1 to form an inner air inlet 4 and an inner air outlet 5, and the inner air inlet 4 and the inner air outlet 5 are respectively arranged at the beginning end and the end of an airflow route of the shell 21. Meanwhile, the shell 21 is also provided with an outer air inlet 6 and an outer air outlet 7, and the outer air inlet 6 and the outer air outlet 7 are also respectively arranged at the beginning and the end of the airflow path of the turbine 2. The inner air inlet 4, the inner air outlet 5, the outer air inlet 6 and the outer air outlet 7 are independent of each other and are respectively provided with a one-way valve for limiting the direction of air flow, so that the unidirectional flow of the air flow is ensured.

In this embodiment, the inner air inlet 4, the outer air inlet 6 and the shell 21 are communicated with each other by a three-way pipe 8.

Further, the power generation device 3 comprises a generator 31 and a motor base 32, the motor base 32 is fixedly connected to the air chamber 1, the generator 31 is arranged on the motor base 32, and the generator 31 is used for generating power by mechanical energy. In this embodiment, the housing 21 and the motor base 32 are both fixed to the top of the air chamber 1 and connected by bolts to form a sealed space, thereby preventing the influence of seawater.

Specifically, the impeller 22 is coupled to the generator 31 through a common rotating shaft and a coupling, as shown in fig. 4, the impeller 22 is a conical spiral impeller, the top end of the impeller 22 is close to the inner air inlet 4, and the bottom surface of the impeller 22 is close to the inner air outlet 5. When the airflow flows to the top end of the impeller 22, the airflow flows away along the spiral line, and the impeller 22 rotates under the reaction force of the airflow because the impeller 22 changes the direction of the airflow, so as to drive the generator 31 to rotate and generate electricity.

The present embodiment further includes a support pillar 10 for fixing, the gas cell 1 is fixed on top of the support pillar 10, and the support pillar 10 is fixed on the sea bottom.

As shown in fig. 2-3, during the operation, when the sea wave continuously surges, the sea wave in the air chamber 1 can also follow the surge, and the space formed by the sea surface and the air chamber 1 can be changed continuously. Therefore, the air pressure in the air chamber 1 also changes. When the sea surface rises, the air pressure is increased, and the air flow can flow out from the inner air inlet 4 of the air chamber 1, pass through the one-way valve and flow to the three-way pipe 8. At this time, since the check valve of the outer air inlet 6 prevents the air flow from leaking, the air flow can only flow into the housing 21 to the right and pass through the impeller 22. The impeller 22 is rotated by the air flow to drive the generator 31 to generate electricity, and the air flow is discharged to the outside through the outlet 7. Similarly, when the sea surface is lowered, the air pressure in the air chamber 1 is reduced, the air flow flows into the three-way pipe 8 from the external air inlet 6, and blows the impeller 22 to rotate, so that the generator 31 is driven to generate electricity. The air flow then flows along the inner air outlet 5 into the interior of the air chamber 1. Therefore, the generator 31 can generate electricity by continuously generating unidirectional air flow regardless of wave energy in any direction, and the wave energy is utilized in an all-round and efficient manner, so that the energy-saving and emission-reducing sustainable development is of great significance.

The device is similar to the principle of a power generation unit, and particularly comprises a gas chamber 1, a gas pipe 9, a plurality of turbines 2 and power generation equipment 3, wherein the gas chamber 1 is of a semi-closed structure with an open bottom, and the gas chamber 1 is intersected with the sea level. The impeller 2 is arranged outside the air chamber 1 and comprises a shell 21 and impellers 22 positioned in the shell 21, and the impellers 22 are correspondingly linked with the power generation equipment 3 one by one.

In particular, the casing 21 of the impeller 2 at the beginning communicates with the air chamber 1 by means of an inner air inlet 4 and with the outside by means of an outer air inlet 6. The casing 21 of the turbine 2 at the end is communicated with the air chamber 1 to form an inner air outlet 5 and an outer air outlet 7. All the turbines 2 are connected in series end to end along the airflow path through the air pipes 9, and the maximum utilization of the airflow is realized.

Specifically, the turbine 2 located in the middle is only provided with the outer air inlet 6 and the outer air outlet 7, the outer air outlet 7 of the previous turbine 2 is connected to the outer air inlet 6 of the next turbine 2 through the air pipe 9, and the air flow in the casing 21 of the turbine 2 at the beginning flows through the turbine 22, passes through the air pipe 9, and then flows to the next turbine 22 to continue generating power until the air flow flows into the air chamber 1 from the casing 21 of the turbine 2 at the end or is discharged to the outside.

Similar to the power generating unit, all the inner air inlet 4, the inner air outlet 5, the outer air inlet 6 and the outer air outlet 7 are provided with one-way valves for limiting the direction of air flow.
