[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0039] The following combination Figures 1 to 6 , describing embodiments of the present invention.

[0040] According to an embodiment of the present invention, Figures 1 to 6 As shown, a water intake tower is provided, including an outer cylinder 1, an inner cylinder 2 and an opening and closing assembly 3. The interior of the outer cylinder 1 is a cavity, and a first water hole 101 is provided on the side wall of the outer cylinder 1. The interior of the inner cylinder 2 is a cavity, and the inner cylinder 2 is arranged inside the outer cylinder 1. A second water hole 201 is provided on the side wall of the inner cylinder 2. The bottom of the inner cylinder 2 is suitable for communicating with the water diversion hole 4. The opening and closing assembly 3 is movably arranged in the first water hole 101 and the second water hole 201. The opening and closing assembly 3 has a water intake state connecting the inner cylinder 2 and the outer cylinder 1, and a closed state separating the inner cylinder 2 and the outer cylinder 1.

[0041] Specifically, in this embodiment, the applicable scenario of the water intake tower is not specifically limited. For example, in this embodiment, the water intake tower is set in the reservoir area.

[0042] like Figures 1 to 3 As shown, in this embodiment, the outer cylinder 1 and the inner cylinder 2 are not specifically limited. For example, in this embodiment, the outer cylinder 1 and the inner cylinder 2 are cylindrical structures, and both are made of reinforced concrete. The outer cylinder 1 has a plurality of first water holes 101 circumferentially provided on its outer wall, and the inner cylinder 2 has a plurality of second water holes 201 circumferentially provided on its side wall. The number of the first water holes 101 and the second water holes 201 is equal. The inner diameter of the outer cylinder 1 is larger than the outer diameter of the inner cylinder 2. The inner cylinder 2 is sleeved within the outer cylinder 1, forming a water passage between the inner cylinder 2 and the outer cylinder 1. The bottom of the inner cylinder 2 is connected to the water transfer tunnel 4. Water from the reservoir enters the water passage from the outside of the outer cylinder 1 through the first water holes 101, then enters the water transfer tunnel 4 through the second water holes 201, and is finally transported by the water transfer tunnel 4 to the water-using equipment.

[0043] In this embodiment, the opening and closing component 3 is movably installed between the inner tube 2 and the outer tube 1. The opening and closing component 3 has a water intake state connecting the inner tube 2 and the outer tube 1, and a closing state separating the inner tube 2 and the outer tube 1. In the water intake state, the first water hole 101 and the second water hole 201 connect the external environment with the delivery hole, and water can enter the water delivery hole 4 from the reservoir outside the water intake tower; in the closing state, the opening and closing component 3 blocks the water from entering the water delivery hole 4 from the reservoir outside the water intake tower.

[0044] The present invention controls the connection and isolation between the inner tube 2 and the outer tube 1 through the opening and closing component 3, thereby realizing the input of water from the outside of the outer tube 1 into the inner tube 2 and into the water transfer tunnel 4 for water extraction. The structure is simple and the operation is convenient, and continuous water extraction can be achieved. The continuity and stability of water extraction are fully guaranteed, and cavitation of the water intake tunnel caused by improper or untimely human operation is avoided.

[0045] In one embodiment, Figures 1 to 4 As shown, the opening and closing component 3 includes a driving component 301, a first pull rod 302, a first baffle 303, a second pull rod 304 and a second baffle 305. The driving component 301 is arranged between the inner tube 2 and the outer tube 1. One end of the first pull rod 302 is connected to the driving component 301, and the other end extends to the first water flow hole 101. The first baffle 303 is connected to the end of the first pull rod 302 away from the driving component 301. The first baffle 303 is specifically in a water-taking state away from the first water flow hole 101, and in a closed state abutting the first water flow hole 101. One end of the second pull rod 304 is connected to the driving component 301, and the other end extends to the second water flow hole 201. The second baffle 305 is connected to the end of the second pull rod 304 away from the driving component 301. The second baffle 305 is specifically in a water-taking state away from the second water flow hole 201, and in a closed state abutting the second water flow hole 201.

[0046] Specifically, in this embodiment, the size of the first baffle 303 is larger than the size of the first water hole 101, and the size of the second baffle 305 is larger than the size of the second water hole 201. When the first baffle 303 abuts against the outer cylinder 1, the first baffle 303 can close the first water hole 101, and when the second baffle 305 abuts against the inner cylinder 2, the second baffle 305 can close the second water hole 201. The driving assembly 301 is arranged between the inner cylinder 2 and the outer cylinder 1, the first baffle 303 is arranged outside the outer cylinder 1, and the second baffle 305 is arranged inside the inner cylinder 2. One end of the first pull rod 302 passes through the first water hole 101 and is connected to the inner side of the first baffle 303, and the other end is connected to the driving assembly 301. One end of the second pull rod 304 passes through the second water hole 201 and is connected to the inner side of the second baffle 305, and the other end is connected to the driving assembly 301.

[0047] In this embodiment, the driving assembly 301 is used to drive the first pull rod 302 and the second pull rod 304 to move in the horizontal direction, thereby driving the first baffle 303 and the second baffle 305 to abut against or separate from the outer cylinder 1 and the inner cylinder 2 respectively.

[0048] The present invention controls the first pull rod 302 and the second pull rod 304 through the driving component 301, and makes the first baffle 303 and the second baffle 305 abut or separate from the outer tube 1 and the inner tube 2, thereby realizing the input of water from the outside of the outer tube 1 into the inner tube 2 and into the water diversion tunnel 4 for water intake. The structure is simple and the operation is convenient, and continuous water intake can be achieved. The continuity and stability of water intake are fully guaranteed, the water flow is smooth, and adverse negative pressure and cavitation damage are avoided, thereby avoiding cavitation of the water intake tunnel caused by improper or untimely human operation.

[0049] In one embodiment, Figures 1 to 4 As shown, the driving assembly 301 includes an airbag 3011 and an air pump 3012 . The airbag 3011 is arranged between the inner tube 2 and the outer tube 1 , and the air pump 3012 is connected to the airbag 3011 .

[0050] Specifically, in this embodiment, the airbag 3011 is disposed between the inner tube 2 and the outer tube 1. The airbag 3011 is not specifically limited in this embodiment. For example, in this embodiment, the airbag 3011 is made of flexible rubber, the flexibility of which can meet the required maximum air pressure. A guide bar is provided at each end of the airbag 3011 to control the deformation direction of the airbag 3011 during inflation and deflation. An air pump 3012 is provided at the top of the airbag 3011. The air pump 3012 inflates and deflates the airbag 3011 to open and close the opening and closing assembly 3. Multiple airbags 3011 can also be provided vertically on the water intake tower according to actual conditions, with each airbag 3011 independently equipped with an air pump 3012.

[0051] In this embodiment, when the air pump 3012 inflates the airbag 3011, the airbag 3011 expands, driving the first and second rods 302, 304 to move horizontally, thereby causing the first and second baffles 303, 305 to move away from the outer tube 1 and inner tube 2, allowing external water to flow into the water transfer tunnel 4 through the first and second water flow holes 101, 201. When the air pump 3012 deflates the airbag 3011, the airbag 3011 contracts, driving the first and second rods 302, 304 to move horizontally, thereby causing the first and second baffles 303, 305 to move toward the outer tube 1 and inner tube 2, abutting against the outer tube 1 and inner tube 2, thereby sealing the first and second water flow holes 101, 201, and preventing external water from entering the water transfer tunnel 4. By adjusting the filling degree of the air bag 3011 through the air pump 3012, the opening degree of the first water hole 101 and the second water hole 201 can be controlled to achieve water intake at different flow rates.

[0052] In this embodiment, the pressure that the pump body can apply is not less than the maximum water pressure that the bottom of the airbag 3011 can withstand, ensuring that the airbag 3011 has sufficient internal pressure to smoothly open the first baffle 303 and the second baffle 305 under high water level conditions. The gas delivery pipeline of the pump body is connected to the interior of the airbag 3011 and needs to be equipped with corresponding power supply equipment.

[0053] The present invention can realize the opening and closing of the opening and closing component 3 by simply controlling the air pressure of the air pump 3012, and can adjust the water intake flow according to the size of the applied air pressure, and has the advantages of simple structure and convenient operation.

[0054] In one embodiment, Figures 2 to 4 As shown, the driving assembly 301 further includes a fixing member 306 , which is disposed on the inner wall of the outer tube 1 or the outer wall of the inner tube 2 , and the airbag 3011 is mounted on the fixing member 306 .

[0055] Specifically, in this embodiment, a through hole is provided at a certain interval along the longitudinal direction on the airbag 3011 , and the fixing member 306 passes through the through hole of the airbag 3011 and is rigidly fixed to the inner wall of the outer tube 1 to ensure the longitudinal stability of the airbag 3011 .

[0056] In this embodiment, the fixing member 306 is rod-shaped and includes a mounting portion and a bending portion. The mounting portion is horizontally inserted into the through hole, and the bending portions at both ends of the mounting portion are connected to the inner wall of the outer tube 1 .

[0057] In the present invention, the airbag 3011 is installed on a plurality of fixing members 306 arranged longitudinally to ensure the longitudinal stability of the airbag 3011 .

[0058] In one embodiment, Figures 2 to 4As shown, the opening and closing assembly 3 also includes a first water stop 307 and a second water stop 308. The first water stop 307 is arranged on the first baffle 303 and is located on the side facing the first water hole 101. The second water stop 308 is arranged on the second baffle 305 and is located on the side facing the second water hole 201.

[0059] Specifically, in this embodiment, there is no specific limitation on the first water stop 307 and the second water stop 308. For example, in this embodiment, the first water stop 307 and the second water stop 308 are rubber water stop strips. The first water stop 307 is installed on the side of the first baffle 303 facing the outer tube 1 using stainless steel bolts, and the second water stop 308 is installed on the side of the second baffle 305 facing the inner tube 2 using stainless steel bolts.

[0060] In the present invention, a first water stop 307 and a second water stop 308 are provided on the first baffle 303 and the second baffle 305 , which can improve the sealing performance of the opening and closing assembly 3 and the inner tube 2 and the outer tube 1 .

[0061] In one embodiment, Figure 5 As shown, the opening and closing assembly 3 further includes guide plates 309 , which are arranged in pairs at the first water hole 101 and the second water hole 201 , and the first pull rod 302 and the second pull rod 304 are located between the two guide plates 309 .

[0062] Specifically, in this embodiment, a pair of guide plates 309 are provided at the first water hole 101, and the first pull rod 302 is passed through the two guide plates 309; a pair of guide plates 309 are provided at the second water hole 201, and the second pull rod 304 is passed through the two guide plates 309.

[0063] In the present invention, the two guide plates 309 can play a limiting and guiding role for the first pull rod 302 and the second pull rod 304, ensuring that the first pull rod 302 and the second pull rod 304 move in the horizontal direction.

[0064] In one embodiment, Figure 4 As shown, a plate 5 is installed at the edges of the first water hole 101 and the second water hole 201 .

[0065] Specifically, in this embodiment, a plate 5 is provided on both sides of the first water hole 101 and the second water hole 201, and the plate 5 wraps the edges of the first water hole 101 and the second water hole 201. When the first water hole 101 and the second water hole 201 are closed, the first water stop and the second water stop can fit tightly with the plate 5 to stop water.

[0066] In this embodiment, the plate 5 is made of a bent stainless steel plate.

[0067] In the present invention, the edges of the first water hole 101 and the second water hole 201 are provided with affixed plates 5 , which can improve the sealing performance between the first water stop 307 and the second water stop 308 and the first water hole 101 and the second water hole 201 .

[0068] In one embodiment, Figures 2 to 4 and Figure 6 As shown, the water intake tower further includes a trash rack 6 , which is mounted on the outer wall of the outer cylinder 1 , and the first water passage 101 is located inside the trash rack 6 .

[0069] The present invention provides a trash rack 6 on the outer wall of the outer cylinder 1 to prevent debris and garbage in the water from entering the water intake tower and causing blockage.

[0070] In one embodiment, the first water hole 101 is provided through the bottom to the top of the outer tube 1 , and the second water hole 201 is provided through the bottom to the top of the inner tube 2 .

[0071] Specifically, in this embodiment, the first water hole 101 is set to pass through from the bottom to the top of the outer cylinder 1, and the second water hole 201 is set to pass through from the bottom to the top of the inner cylinder 2, which is convenient for continuous water extraction. The height of the first water hole 101 and the second water hole 201 needs to be flexibly arranged according to specific circumstances, and the width of the first water hole 101 and the second water hole 201 can also be flexibly adjusted according to actual needs.

[0072] In this embodiment, the number of the first water holes 101 and the second water holes 201 is not specifically limited. For example, in this embodiment, four first water holes 101 and four second water holes 201 are provided. The four first water holes 101 are symmetrically provided on the outer cylinder 1, and the second water holes 201 are provided opposite to the first water holes 101.

[0073] In this embodiment, the trash rack 6 is arranged along the entire length of the first water hole 101 of the outer tube 1 to prevent debris and garbage from entering the water intake tower and causing blockage under different water level conditions.

[0074] In the present invention, the first water hole 101 is provided through the bottom to the top of the outer cylinder 1 to facilitate continuous water intake.

[0075] In one embodiment, the diameter of the inner cylinder 2 is not less than the diameter of the water transfer hole 4 .

[0076] Specifically, in this embodiment, the diameter of the inner cylinder 2 is larger than the diameter of the water transfer hole 4 , which can ensure that water flows from the inner cylinder 2 into the water transfer hole 4 .

[0077] The working principle of the present invention is as follows:

[0078] When it is necessary to draw water through the water intake tower, the operator turns on the pump body in the operating room at the top of the water intake tower, and continuously pressurizes the inside of the air bag 3011 through the pump body. The expansion of the air bag 3011 drives the first baffle 303 and the second baffle 305 to move toward the two ends of the air bag 3011, so that the water flow can flow into the water intake tower through the first water hole 101 and the second water hole 201, and then the water is transported through the water delivery hole 4. By adjusting the internal pressure of the air bag 3011, the displacement size of the first baffle 303 and the second baffle 305 can be controlled to adjust the flow rate. The trash rack 6 set on the outer tube 1 can prevent garbage, dead wood, branches, etc. in the water body from entering the water intake tower, thereby ensuring that the water intake tower works normally. When it is necessary to close, the operator opens the air release valve of the pump body to discharge the gas inside the airbag 3011. The internal pressure of the airbag 3011 gradually decreases, and the combined effect of the water pressure causes the airbag 3011 to deflate, thereby driving the first baffle 303 and the second baffle 305 to shrink toward the inside of the airbag 3011. When the first water stop and the second water stop are tightly fitted with the plate 5 at the first water hole 101 and the second water hole 201, it is closed.

[0079] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
