Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy power generation, and particularly relates to a device for realizing power generation by utilizing water buoyancy and object gravity. Background Art

[0002] In daily life, we often see large cargo ships transporting goods at sea, which shows that as long as there is enough water, ships can carry a large amount of goods. Sometimes we also see that some ships are stranded on the shore because of lack of water after the sea water recedes, but the weight of the ship remains unchanged. This shows that in a large pool, as long as the amount of water is controlled, the rise and fall of the ship can be controlled, and the weight of the object remains unchanged. Therefore, the above principle can be used to realize the buoyancy of water and the gravity of the object to generate electricity.

[0003] Patent No. ZL202010802832.0 discloses a device for generating electricity and transporting water by using the buoyancy of water and the gravity of an object.

However, the above patent requires the use of the water bag of the water storage device in the groove to achieve power generation, and the control of water inlet and water outlet is carried out with the help of control equipment, so the construction cost is relatively high.

The bottom water outlet 4 of the water tank 20 is connected, and the one-way flow direction of the one-way valve 5 in the first pipe 3 is: the bottom water outlet 4 of the second water tank 20 of the first conveying device flows to the bottom water inlet 21 of the first water tank 1 of the second water conveying device 24; the bottom water outlet 4 of the second water tank 20 of the second conveying device is connected with the bottom water outlet 4 of the second water tank 20 of the second conveying device through the first pipe 3, and the one-way flow direction of the one-way valve 5 in the first pipe 3 is: the bottom water outlet 4 of the second water tank 20 of the second conveying device flows to the bottom water outlet 4 of the second water tank 20 of the second conveying device;

It should be noted that the height of the first generator 26 needs to be lower than the height of the top of the first water tank 1.

[0050] In this embodiment, the ratio of the flow rates of water in the first water tank 1 , the second water tank 20 and the third water tank 9 is 1:1:1.

[0051] It should be noted that the outer side of the actuator 2 is made of stainless steel, or other materials that are not easy to rust and have high density, such as copper.

Correspondingly, the shapes of the second water tank wall 17 and the third water tank wall 6 can be designed to be square, circular, polygonal, etc. according to actual needs.

[0053] The working principle of the device for generating electricity by utilizing water buoyancy and object gravity in this embodiment is as follows:

[0054] Install the bottom of the water tank of the first water delivery device 23, the second water delivery device 24 and the third water delivery device 25 on the same horizontal plane, and assemble the three water delivery devices as a group. Run the following process:

[0055] Start the operation process of the device:

[0056] The first step is to add water to the second water tanks 20 of the first water delivery device 23, the second water delivery device 24 and the third water delivery device 25 respectively. When the water level reaches a preset level, the first floating object 19 rises.

[0057] Step 2: add water to the third water tank 9 of the third water delivery device 25. When the water level reaches the preset water level, the water level will flood the return pipe of the water tank 8. At this time, the water tank 8 will automatically work, and the rubber valve of the water tank 8 will open. The water in the third water tank 9 of the third water delivery device 25 will flow into the second water tank 20 of the third water delivery device 25.

[0058] Step 3: add water to the third water tank 9 of the first water delivery device 23. When the water reaches the preset water level, the water level floods the return pipe of the water tank 8. At this time, the water tank 8 automatically works, and the rubber valve of the water tank 8 opens. The water in the third water tank 9 of the first water delivery device 23 flows into the second water tank 20 of the first water delivery device 23. At this time, the water level of the second water tank 20 of the first water delivery device 23 rises, and the first floating object 19 of the first water delivery device 23 rises, and drives the actuator 2 of the first water delivery device 23 to rise. After space appears in the first water tank 1 of the first water delivery device 23, the water in the second water tank 20 of the third water delivery device 25 is led to the first water tank 1 of the first water delivery device 23 through the one-way valve 5;

[0059] Step 4: add water to the third water tank 9 of the second water delivery device 24. When the water reaches the preset water level, the water level floods the return pipe of the water tank 8. At this time, the water tank 8 automatically works, and the rubber valve of the water tank 8 opens. The water in the third water tank 9 of the second water delivery device 24 flows into the second water tank 20 of the second water delivery device 24. At this time, the water level of the second water tank 20 of the second water delivery device 24 rises, and the first floating object 19 of the second water delivery device 24 rises, and drives the actuator 2 of the second water delivery device 24 to rise. After space appears in the first water tank 1 of the second water delivery device 24, the water in the second water tank 20 of the first water delivery device 23 is introduced into the first water tank 1 of the second water delivery device 24 through the one-way valve 5;

[0060] Step 5. After the water from the second water tank 20 of the first water conveying device 23 flows to the first water tank 1 of the second water conveying device 24, the buoyancy of the second water tank 20 of the first water conveying device 23 decreases. At this time, the first floating object 19 of the first water conveying device 23 drives the actuator 2 to descend, and the actuator 2 of the first water conveying device 23 moves downward. In addition, the one-way valve 5 in the first pipeline 3 connected to the first water tank 1 of the first water conveying device 23 acts. The water in the first water tank 1 of the first water conveying device 23 can only overflow upward along the gap between the actuator 2 and the first water tank wall 14. When the water level rises to the water outlet 4 of the second pipeline 12, it flows to the first generator 26 and the third water tank 9 of the third water conveying device 25. At this time, the device is started.

[0061] After the device is started, it will enter the automatic operation process:

[0062] Step 6. When the water level of the third water tank 9 of the third water delivery device 25 reaches the preset water level, the water level floods the return pipe of the water tank 8. At this time, the water tank 8 automatically works, and the rubber valve of the water tank 8 opens. The water in the third water tank 9 of the third water delivery device 25 flows to the second water tank 20 of the third water delivery device 25. After the water is stored in the second water tank 20 of the third water delivery device 25, the first floating object 19 of the third water delivery device 25 rises, and drives the actuator 2 of the third water delivery device 25 to rise, resulting in free space in the first water tank 1 of the third water delivery device 25. Due to the water level difference, the first water tank 1 of the third water delivery device 25 leads the second water tank 20 of the second water delivery device 24 through the first pipeline 3.

[0063] Step 7. After the water level in the second water tank 20 of the second water conveying device 24 drops and drives the actuator 2 of the second water conveying device 24 to move downward, the one-way valve 5 in the first pipe 3 of the second water conveying device 24 cuts off the water flow. The water in the first water tank 1 of the second water conveying device 24 can only overflow upward along the gap between the actuator 2 and the first water tank wall 14. After the water level rises to the water outlet position of the second pipe 12, it flows to the third water tank 9 of the first water conveying device 23 and the first generator 26.

[0064] Step 8. When the water level of the third water tank 9 of the first water conveying device 23 reaches the preset water level, the water level floods the return pipe of the water tank 8. At this time, the water tank 8 automatically works, and the rubber valve of the water tank 8 opens. The water in the third water tank 9 of the first water conveying device 23 flows to the second water tank 20 of the first water conveying device 23. After the water is stored in the second water tank 20 of the first water conveying device 23, the first floating object 19 of the first water conveying device 23 rises, and drives the actuator 2 of the first water conveying device 23 to rise, resulting in the first water tank 1 of the first water conveying device 23 having free space. Due to the water level difference, the first water tank 1 of the first water conveying device 23 leads the second water tank 20 of the third water conveying device 25 through the first pipeline 3.

[0065] Step 9. After the water level in the second water tank 20 of the third water conveying device 25 drops and drives the actuator 2 of the third water conveying device 25 to move downward, the one-way valve 5 in the first pipe 3 of the third water conveying device 25 cuts off the water flow. The water in the first water tank 1 of the third water conveying device 23 can only overflow upward along the gap between the actuator 2 and the first water tank wall 14. After the water level rises to the water outlet position of the second pipe 12, it flows to the third water tank 9 of the second water conveying device 24 and the first generator 26.

[0066] Step 10. When the water level of the third water tank 9 of the second water delivery device 24 reaches the preset water level, the water level floods the return pipe of the water tank 8. At this time, the water tank 8 automatically works, and the rubber valve of the water tank 8 opens. The water in the third water tank 9 of the second water delivery device 24 flows into the second water tank 20 of the second water delivery device 24. After the second water tank 20 of the second water delivery device 24 stores water, the first floating object 19 of the second water delivery device 24 rises, and drives the actuator 2 of the second water delivery device 24 to rise, resulting in free space in the first water tank 1 of the second water delivery device 24. Due to the water level difference, the first water tank 1 of the second water delivery device 24 leads the second water tank 20 of the first water delivery device 23 through the first pipeline 3.

[0067] Step 11. After the water level in the second water tank 20 of the first water conveying device 23 drops and drives the actuator 2 of the first water conveying device 23 to move downward, the one-way valve 5 in the first pipeline 3 of the first water conveying device 23 cuts off the water flow. The water in the first water tank 1 of the first water conveying device 23 can only overflow upward along the gap between the actuator 2 and the first water tank wall 14. After the water level rises to the water outlet position of the second pipeline 12, it flows to the third water tank 9 of the third water conveying device 25 and the first generator 26.

[0068] The device repeatedly runs the sixth to eleventh steps to achieve continuous power generation of the first generator 26 .

[0069] The utility model uses the buoyancy of water and the gravity of objects to realize power generation. The device uses water and the first floating object 19 to increase the water flow velocity. The water enters the first water tank 1 and the actuator 2 to store water at the same time, so that the floating device in the second water tank 20 drives the actuator 2 to float vertically to a certain height. The working principle of the one-way valve 5 and the water bladder 8 is used to make the weight of the water in the second water tank 20 and the first floating object 19 drive the actuator 2 to move vertically downward, so that the water is quickly squeezed through the gap between the actuator 2 and the first water tank wall 14 and discharged, and guided by the direction of the second pipe 12 so that the first generator 26 works to generate electricity. The scheme of the application can effectively reduce the damage to the surrounding environment by only using water and the floating device to increase the water flow velocity. It only needs to be directly laid in place under normal temperature and sufficient space to realize continuous hydropower generation; at the same time, by using the water bladder 8 and the one-way valve 5 to replace the water inlet valve and the drain valve in the prior art, the water storage cost of the original water storage device is reduced, and the construction cost is effectively reduced.

[0070] The device for generating electricity by utilizing water buoyancy and object gravity in this embodiment further includes a water electromagnetic valve 7 , one end of which is connected to the rubber valve at the lower end of the water tank 8 , and the other end is connected to the upper part of the second water tank 20 .

[0071] In this embodiment, the water solenoid valve 7 adopts a water normally open solenoid valve, which is an electromagnetic device specially used to control water flow. When the power is not turned on, the valve of the solenoid valve is in an open state, allowing water to flow through. When the power is turned on, the electromagnet in the solenoid valve will generate a magnetic field to attract the valve core, thereby closing the valve and preventing water from flowing through. It has the advantages of simple structure, easy installation, fast response speed and strong corrosion resistance, and can adapt to various water quality environments.

[0072] In specific implementation, when needing to stop or repair, close the switch of water electromagnetic valve 7, when needing to start again, open water electromagnetic valve 7 again, equipment just can run.Can play the effect of flexible operation to the start or stop of equipment through water electromagnetic valve 7.

[0073] In this embodiment, a second generator 22 is provided below the water outlet 4 of the water solenoid valve 7 .

[0074] In a specific implementation, the second generator 22 is installed below the water outlet 4 of the water solenoid valve 7 , and the second generator 22 generates electricity by utilizing the impact force of the water flow from the high water level in the third water tank 9 to the low water level in the second water tank 20 .

[0075] The device for generating electricity by utilizing water buoyancy and object gravity in this embodiment also includes a second floating object 10, a first limiting hole is provided in the middle of the second floating object 10; a vertical limiting column 11 is provided on the third water tank 9, and the cross-sectional size of the vertical limiting column 11 is smaller than the first limiting hole, and the vertical limiting column 11 is inserted into the first limiting hole.

[0076] In a specific implementation, since the cross-sectional size of the vertical limiting column 11 is smaller than the first limiting hole, the vertical limiting column 11 and the second floating object 10 can form a sliding connection. The second floating object 10 slides vertically on the vertical limiting column 11, which ensures that the second floating object 10 remains stable when floating up and down. The up and down movement of the second floating object 10 can be used to connect to an external power generation equipment for power generation.
