Description

A device that harnesses tidal power

technical field

The utility model relates to a power generating device, in particular to a device utilizing tidal power generation.

Background technique

As we all know, the traditional method of using water to generate electricity is to use water with a certain drop to flow from a high place to a low place, and its potential energy is converted into kinetic energy to drive the hydroelectric generator to rotate to generate electricity. Usually, a reservoir is set at a higher position to store water, and a hydroelectric generator is installed at a lower position, and water falls from a high place to do work on the blades of the hydroelectric generator. This method usually uses a large amount of water to impact the smaller blades, and a large amount of water flows through the periphery of the blades or between the blades, so a large amount of hydraulic power is not fully utilized, resulting in a waste of a large amount of hydraulic resources.

In today's world where energy is increasingly scarce, how to save energy and make full and effective use of energy has become an important issue that must be solved in the current world development. Due to the serious damage to the environment, many rivers have stopped flowing and dried up. Seriously inadequate. In addition to improving hydroelectric generators to increase their power generation efficiency, people also thought of using tides to generate electricity.

For example, Chinese Patent No. 86103832 discloses a "floating body tidal power generation method". A water level difference is formed between the water level inside and the sea surface, and the potential energy of the water level difference is used to drive the hydroelectric generating set to generate electricity. This power generation method is basically the same as the traditional hydroelectric power generation method, the only difference being that the water level drop used for power generation is generated by the fluctuation of the tide. Because the drop formed by the tide is generally no more than five meters, and the water turbine requires a large water level drop, the power generation efficiency of this method is extremely low, and it can only generate electricity at intervals, so it cannot be popularized and applied.

The working process of the device will be described in detail below.

In the initial state, the water inlet valves 110, 210, and 310 of each water tank 1, 2, and 3 are opened, and the drain valves 120, 220, and 320 are closed. When the tide rises, seawater enters each water tank 1, 21, and 31 through the water inlets 11, 21, and 31. In 2 and 3, the water level in each water tank 1, 2, 3 rises gradually, and the floating hammers 13, 23, 33 in each water tank 1, 2, 3 rise thereupon. When the water level rises to a certain height, each The first control teeth 142, 242, 342 of a rod body 14, 24, 34 drive the corresponding water inlet valve closing control wheel 18, 28, 38 to move, so that each water inlet valve 110, 210, 310 is closed, and each water inlet 11, 21, 31 are blocked and no longer enter water; the last water tank n is also full of water in the above-mentioned steps, and the small water tank a is also full of water.

At this time, manually open the drain valve 110 of the first water tank 1, the seawater in the first water tank 1 is gradually discharged into the reservoir 10, and its water level gradually drops, and its floating hammer 13 drops thereupon. When falling to the lowest position, The second/third control tooth 144 on the rod body 14 drives the drain valve to close and control 19 rounds of action, so that the drain valve 120 of the first water tank is closed, and the fourth control tooth 143 drives the drain valve to open the control wheel 17 to make the second The drain valve 220 of the second water tank 2 is opened;

The seawater in the second water tank 2 starts to be gradually discharged into the reservoir 10. When the floating hammer 23 drops to a certain position, the second/third control tooth on the rod body 24 drives the water inlet valve to open the control wheel 26 to move. The water inlet valve 110 of the first tank 1 is opened for the next water intake; and when the water level of the second tank 2 drops to the lowest position, the second/third control tooth on the rod body 24 drives the corresponding drain valve Close control wheel 29 action, make its drain valve 220 close, simultaneously its fourth control tooth drives corresponding drain valve to open control wheel 27, opens the drain valve 320 of the 3rd tank 3, makes the 3rd tank 3 begin to drain.

The working principle of the third water tank 3 is similar to that described above, and its water inlet valve opening control wheel 36 can control the water inlet valve 210 of the second water tank 2 to open. By analogy, the action process of each water tank after the third water tank 3 is also the same. When the last tank n is drained, the water level in the small tank is at its water inlet a1, and the first tank 1 has been filled with water again. At this time, the sea level just rises to the highest again, and the drain valve of the last tank n is opened. The control wheel n7 controls the opening of the drain valve 120 of the first water tank 1, so that the first water tank 1 starts to drain water again and enters the next cycle, and the drain valve of the last water tank n opens. The control wheel n7 simultaneously controls the drainage of the small water tank a The valve a20 is opened so that it can start draining. When the water in the small tank a is drained, its drain valve is closed and the control wheel a9 is linked to control its own drain valve a20 to be closed, so that the small tank a enters the water tank that can be filled again. state, and its water inlet valve opening control wheel a6 is linked to control the water inlet valve n10 of the last water tank n to open, so that the last water tank n can also enter the water-filled state again.

It can be seen from the above that the function of designing the small water tank a is that the small water tank a can control the last water tank n to open its water inlet valve n10 after the water is drained, so as to ensure the smooth drainage of the last water tank n and make the last A water tank n can successfully carry out water filling next time, to ensure that the aforementioned water tanks carry out continuous circulation drainage. In this way, cycle control can be formed, and the total number of required water tanks can be calculated according to the tidal cycle and the time of water intake and drainage of each tank, so that uninterrupted and continuous power generation can be realized. The height of each control tooth or control wheel can be designed to adjust, and according to the height difference of tidal water level, the height of each control tooth or control wheel can be adjusted to adapt to tidal water level.

The dotted lines in Figure 1 and Figure 2 indicate the control relationship between each control wheel and each water inlet valve and drain valve. There are many kinds of linkage control mechanisms, such as chain drive, belt drive, gear drive, etc. It is a prior art and will not be described here.

The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto. For example, using this idea, it can be easily designed to change the rod body in the utility model into a gear body, and a chain is connected on the floating hammer, the chain is wound on the gear body, and the other end of the chain is connected to a gear body. Suspended heavy objects of appropriate weight, the floating hammer moves up and down with the water level in the water tank, and drives the gear body to rotate, thereby driving the generator to generate electricity. Moreover, the utility model is not only suitable for using tidal power generation, it only needs to have a water source with a certain drop to fill the water tank in the utility model, in this case, only need to set at least two water tanks to realize automatic circulation control , to achieve the purpose of uninterrupted power generation. Any non-substantial modification to the utility model by utilizing this conception shall be an act of violating the protection scope of the utility model.
