Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower equipment technology, specifically to a buoyancy-driven water lifting device for water conservancy and hydropower. Background Technology

[0002] In the field of water conservancy and hydropower engineering, comprehensive surveying and design are crucial before construction begins. Among these, water quality testing of the target area is a key step in the process. Accurate water quality testing data is fundamental to ensuring the smooth progress of subsequent projects, guaranteeing the safety and effectiveness of water conservancy and hydropower projects, and protecting the ecological environment. In water conservancy and hydropower projects, water samples are typically collected manually using containers such as sampling buckets.

[0003] Chinese patent (authorization announcement number: CN 217211598 U, authorization announcement date: 2022.08.16) proposes a buoyancy-driven water lifting device for water conservancy and hydropower. This patent involves setting a movable plate below a water-collecting bucket, a counterweight below the movable plate, and a float plate above the movable plate via a support plate. When collecting water, the water-collecting bucket is dropped into the water, and it floats on the water surface under the action of buoyancy. The movable plate moves downward under the action of the counterweight, and water enters the water-collecting bucket through the gap between the movable plate and the water-collecting bucket. The float plate moves upward under the action of the water in the water-collecting bucket until the water-collecting bucket is full. At this time, the movable plate is in contact with the connecting plate at the bottom of the water-collecting bucket, so that the device can complete the water collection work quickly and conveniently.

[0004] However, this patent requires the bucket to be filled with water before it can be sealed by the cooperation of the movable plate and the connecting plate. When the water level of the sampling river is lower than the height of the bucket, the bucket cannot be filled with water, and the movable plate cannot be fitted with the connecting plate to achieve a seal, thus making water collection impossible. In order to facilitate convenient and quick water collection in rivers with different water levels, we propose a buoyancy-driven water lifting device for water conservancy and hydropower. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a buoyancy-driven water lifting device for water conservancy and hydropower, which can conveniently and quickly extract water in rivers with different water levels.

[0014] Beneficial effects

[0015] This utility model provides a buoyancy-driven water lifting device for water conservancy and hydropower. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] This buoyancy-driven water lifting device for water conservancy and hydropower operates by placing it in a river. Under the influence of a counterweight, the bucket descends, while the float slides upwards within the mounting cover due to buoyancy. Pressure changes cause river water to quickly enter the bucket, enabling convenient and efficient water collection. Once the internal and external pressures of the bucket are balanced, a spring-loaded sealing cover closes the mounting cylinder to prevent water leakage and ensure the integrity of the water sample. During water collection, the lifting plate rises to a certain height to complete the process, requiring no special requirements on the river's water level, making it widely applicable. After water collection, manually rotating the connecting block to detach from the counterweight allows for easy drainage, making operation simple. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a buoyancy water lifting device for water conservancy and hydropower, including a barrel 1, a bottom plate 10 fixedly connected to the bottom of the barrel 1, a counterweight block 12 fixedly connected to the bottom of the bottom plate 10, a plurality of sets of mounting holes 14 opened on the bottom plate 10, a lifting plate 8 slidably connected to the inner wall of the barrel 1, a lifting assembly for driving the lifting plate 8 to rise and fall on the barrel 1, and a sealing assembly for preventing water in the barrel 1 from flowing out of the mounting holes 14 on the barrel 1;

[0026] The sealing assembly includes several sets of mounting cylinders 16, which are fixedly mounted on mounting holes 14. A mounting plate 20 is fixedly connected to the inner wall of the mounting cylinder 16. Several sets of through holes are opened on the mounting plate 20. A telescopic rod 22 is fixedly connected to the top of the mounting plate 20. A sealing cover 23 is fixedly connected to the top of the telescopic rod 22. A spring 21 is fixedly installed between the sealing cover 23 and the mounting plate 20. The spring 21 is sleeved on the outside of the telescopic rod 22. The inner wall of the sealing cover 23 is slidably connected to the outer wall of the mounting cylinder 16.

[0027] In use, the entire device is placed in the river. Under the action of the counterweight 12, the barrel 1 falls vertically in the river water. During the fall, the lifting plate 8 moves upward under the action of the lifting component, which reduces the air pressure in the inner cavity of the barrel 1. Under the pressure of the external air pressure, the river water pushes the sealing cover 23 into the barrel 1, causing the air pressure in the inner cavity of the barrel 1 to gradually rise. When the air pressure in the inner cavity of the barrel 1 reaches equilibrium with the external atmospheric pressure, the external air pressure no longer exerts pressure on the river water. Under the action of the spring 21, the sealing cover 23 moves down to cover the mounting cylinder 16, preventing the water in the barrel 1 from flowing out, thus completing the water collection process. During the water collection process, the lifting plate 8 rises to a certain height to complete the water collection, and it can ensure that the water in the barrel 1 does not flow out. There are no special requirements for the river water level, and it has a wide range of applications.

[0028] The lifting assembly includes several sets of mounting covers 4, which are fixedly connected to the outer wall of the barrel 1. A float 9 is slidably installed on the inner wall of the mounting cover 4. Several sets of connecting pipes 3 corresponding to the mounting covers 4 are fixedly connected to the inner wall of the barrel 1. Several sets of connecting holes 24 are opened on the barrel 1 to connect the connecting pipes 3 and the mounting covers 4. The connecting pipes 3 slide through the lifting plate 8. Several sets of lifting covers 13 are fixedly connected to the bottom of the lifting plate 8. The lifting covers 13 are sleeved on the outside of the connecting pipes 3. Several sets of connecting covers 7 are fixedly connected to the inner wall of the barrel 1. The inner wall of the connecting cover 7 is slidably connected to the outer wall of the lifting cover 13.

[0029] During the descent of the barrel 1, the float 9 slides upward in the inner wall of the mounting cover 4 under the action of buoyancy, squeezing the air in the inner cavity of the mounting cover 4 into the space between the connecting cover 7 and the lifting cover 13 through the connecting hole 24 and the connecting pipe 3. As a result, the air pressure between the connecting cover 7 and the lifting cover 13 increases, and the air pressure causes the connecting cover 7 to drive the lifting plate 8 to rise.

[0030] The mounting sleeve 16 is fitted with a sealing ring 19, and the sealing ring 19 and the sealing cover 23 are respectively provided with sealing rings on the side that are close to each other.

[0031] The tension of spring 21 causes the two sets of sealing rings to fit tightly together, further improving the sealing performance.

[0032] A connecting block 11 is threaded onto the counterweight 12, and a sealing gasket 17 is fixedly connected to the top of the connecting block 11. A sealing hole 15 corresponding to the sealing gasket 17 is opened on the base plate 10.

[0033] After water is drawn, manually rotate the connecting block 11 to lower it and disengage it from the counterweight block 12, thus draining the water from the bucket 1.

[0034] Several sets of hanging lugs 2 are fixedly connected to the top of the barrel 1 for easy fixing of the traction rope. A support frame 6 is fixedly connected to the bottom of the barrel 1, and a dial 5 is provided on the barrel 1.

[0035] A filter screen 18 is installed at the bottom of the mounting cylinder 16 to prevent insects, aquatic plants and other debris from entering the barrel 1. A limit ring is installed at the bottom of the mounting cover 4 to prevent the float 9 from falling out of the mounting cover 4.

[0036] Working principle: When in use, tie the traction rope to the hanging ear 2 and put the whole device into the river. Under the action of the counterweight 12, the barrel 1 falls vertically in the river water. During the fall, the float 9 slides upward in the inner wall of the mounting cover 4 under the action of buoyancy. The air in the inner cavity of the mounting cover 4 is squeezed into the space between the connecting cover 7 and the lifting cover 13 through the connecting hole 24 and the connecting pipe 3. The air pressure between the connecting cover 7 and the lifting cover 13 increases. Under the action of air pressure, the connecting cover 7 drives the lifting plate 8 to rise. The air pressure in the inner cavity of the barrel 1 decreases. Under the pressure of the external air pressure, the river water pushes up the sealing cover 23 and enters the barrel 1, causing the air pressure in the inner cavity of the barrel 1 to gradually rise. When the air pressure in the inner cavity of the barrel 1 reaches equilibrium with the external atmospheric pressure, the external air pressure no longer exerts pressure on the river water. Under the action of the spring 21, the sealing cover 23 moves down to cover the mounting cylinder 16, so that the water in the barrel 1 can no longer flow out, and the water collection is completed. During water collection, the lifting plate 8 rises to a certain height to complete the water collection process, ensuring that the water in the bucket 1 does not flow out. It has no special requirements on the river water level and is widely applicable. After water collection is completed, manually rotate the connecting block 11 to lower it and disengage it from the counterweight block 12, thus draining the water from the bucket 1.
