Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a river sluice for water conservancy projects. Background Art

[0002] A sluice is a low-head hydraulic structure built on rivers and channels that uses gates to control flow and adjust water levels. Closing the gates can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic water. Opening the gates can discharge floods, waterlogging, sewage, or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining, discharging, or taking in water.

[0003] The river sluice used in existing water conservancy projects includes a hydraulic cylinder, a hydraulic rod and a gate. The gates are oppositely and rotatably installed on both sides of the concrete pier. The hydraulic rod is rotatably connected to the inner sides of the two gates. The hydraulic cylinder drives the hydraulic rod to extend and retract by means of extension and retraction. The hydraulic rod can drive the two gates to rotate relative to each other by means of extension and retraction. When the two gates are closed to each other, the water retaining function of the sluice is realized. When the two gates are opened to each other, the drainage function of the sluice is realized.

[0004] Although the existing river sluice gates can realize the functions of water blocking and drainage, during the water blocking stage, the impact force of the river water on the two gates will be directly transmitted to the hydraulic rod and hydraulic cylinder, which will not only cause the hydraulic cylinder to bear a large load and affect its service life, but also easily cause the hydraulic cylinder to rupture, causing it to lose its original function, and then cause the sluice gate to lose its water blocking and drainage functions.

[0005] Therefore, in view of the above status quo, there is an urgent need to develop a river sluice for water conservancy projects to overcome the shortcomings in current practical applications. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] like Figures 1 to 5 As shown, as an embodiment of the present invention, a river sluice for a water conservancy project includes a first gate plate 1 and a second gate plate 7, both of which are arc-shaped plate structures, and the inner sides of the first gate plate 1 and the second gate plate 7 are both arranged with supporting steel frames in a horizontal and vertical staggered manner, and the ends of the first gate plate 1 and the second gate plate 7 that are away from each other are rotatably installed in the storage cavity 61 opened on both sides of the concrete gate pier 6 through the second steel hinge seat 4, and the first gate plate 1 and the second gate plate 7 are both located between the concrete gate pier 6, and also include: A bracket assembly 2, wherein the bracket assembly 2 is fixed to the inner side of the first gate plate 1 and the second gate plate 7, one end of the bracket assembly 2 is rotatably connected to one end of the regulating mechanism 3, and the other end of the regulating mechanism 3 is installed in the storage cavity 61; The fixed calibration mechanism 5 comprises a first fixed block 51, a second fixed block 52, a control component 53 and a fixed component 54. The first fixed block 51 is distributed on the side wall at the other end of the second gate plate 7. The second fixed block 52 is symmetrically arranged at the upper and lower ends of the first fixed block 51 and fixed on the side wall at the other end of the first gate plate 1. The control component 53 is slidably installed on the second fixed block 52. A magnetic attraction component 534 is installed in the control component 53. The magnetic attraction component 534 is symmetrically arranged at the upper and lower ends of the first fixed block 51, and the two magnetic attraction components 534 at the upper and lower ends of the first fixed block 51 have opposite magnetic properties. The fixed component 54 is installed on the end of the control component 53 close to the first fixed block 51, and the fixed component 54 cooperates with the fixed grooves 511 opened on the upper and lower end surfaces of the first fixed block 51.

[0027] In this embodiment, the regulating mechanism 3 can drive one end of the first gate plate 1 and the second gate plate 7 to rotate around their respective second steel hinge seats 4 by means of hydraulic expansion and contraction and cooperation with the bracket assembly 2, so that the other ends of the first gate plate 1 and the second gate plate 7 are precisely docked, thereby realizing the water blocking function of the sluice; When the first gate plate 1 and the second gate plate 7 are closed, the two magnetic suction members 534 at the upper and lower ends of the first fixed block 51 can drive their respective control components 53 to approach each other by attracting each other, and the two control components 53 drive their respective fixing components 54 to move in the direction close to the first fixed block 51, and the two fixing components 54 respectively cooperate with the fixing grooves 511 at the upper and lower ends of the first fixed block 51 by moving. The fixing components 54 can not only calibrate the rotation angle of the first gate plate 1 and the second gate plate 7 by cooperating with the fixing grooves 511, but also when the rotation angle of the first gate plate 1 and the second gate plate 7 does not meet the requirements, the fixing components 54 cannot normally cooperate with the fixing grooves 511, so that the staff can be warned, so that the staff can check the first gate plate 1, the second gate plate 7 and the regulating mechanism 3 in time, avoid the phenomenon of poor closure of the first gate plate 1 and the second gate plate 7, ensure that the sluice can normally realize the water retaining function, and can also realize the connection between the first fixed block 51 and the second fixed block 52, so that the first gate plate 1 and the second gate plate 7 are connected as a whole; At this time, the first gate plate 1 and the second gate plate 7 are connected as a whole with both sides of the concrete pier 6 through the fixed calibration mechanism 5 and the second steel hinge seat 4. This can not only improve the connection stability between the first gate plate 1 and the second gate plate 7, thereby improving the water-blocking quality and water-blocking efficiency of the sluice, but also avoid the first gate plate 1 and the second gate plate 7 from applying excessive pressure to the regulating mechanism 3 during the water-blocking process, reduce the load of the regulating mechanism 3, and then reduce its failure rate, thereby extending the overall service life of the sluice.

[0028] In a preferred embodiment, the magnetic attraction member 534 is preferably an electromagnet that can be powered by electricity, but can also be replaced by a hydraulic telescopic structure. The hydraulic telescopic structure can also drive the control component 53 to move by its own hydraulic telescopic method, and can also achieve the above-mentioned functions. The specific structure can be adaptively adjusted according to the actual environment.

[0029] like Figures 2 to 5 As shown, as a preferred embodiment of the present invention, a first through hole 512 is opened in the middle of the first fixing block 51, and a second through hole 522 is opened in the middle of the second fixing block 52. The first through hole 512 and the second through hole 522 are both used for the magnetic suction member 534 to move. The opening of the first through hole 512 and the second through hole 522 can not only facilitate the movement of the magnetic suction member 534, reduce the resistance and friction encountered by the magnetic suction member 534 during the movement, improve its movement efficiency and response speed, so that it can complete the fixing operation of the first fixing block 51 and the second fixing block 52 more quickly, but also provide sufficient space for the mutual attraction of the two magnetic suction members 534, ensure that the magnetic suction members 534 can quickly and fully attract each other during the movement, thereby forming a strong attraction to enhance the stability of the connection between the first fixing block 51 and the second fixing block 52.

[0030] like Figures 2 to 5 As shown, as a preferred embodiment of the present invention, the control component 53 includes a mounting plate 531, a guide rod 532, a mounting column 533 and a spring 535. The mounting plate 531 is arranged on one side of the second fixed block 52. A spring 535 is installed between the mounting plate 531 and the second fixed block 52. A guide rod 532 is circumferentially distributed on one side of the mounting plate 531. The guide rod 532 is slidably matched with a mounting hole 521 circumferentially opened on the second fixed block 52. One end of the guide rod 532 passes through the mounting hole 521 and is fixedly connected to one side of the fixed component 54. One end of the mounting column 533 is fixed to one side of the mounting plate 531. The other end of the mounting column 533 passes through the second fixed block 52 and the fixed component 54 in sequence and is fixedly connected to the magnetic suction component 534.

[0031] In this embodiment, the two magnetic members 534 at the upper and lower ends of the first fixing block 51 can drive their respective mounting posts 533 to approach each other by attracting each other, and the two mounting posts 533 drive their respective mounting plates 531 to move toward the direction close to the first fixing block 51, and at this time, the spring 535 is in a compressed state; The two mounting plates 531 drive the two fixing components 54 to move toward the direction close to the first fixing block 51 through the guide rod 532. The two fixing components 54 are respectively matched with the fixing grooves 511 at the upper and lower ends of the first fixing block 51 by moving. The fixing components 54 can not only calibrate the rotation angle of the first gate plate 1 and the second gate plate 7 by matching with the fixing grooves 511, but also realize the connection between the first fixing block 51 and the second fixing block 52, so that the first gate plate 1 and the second gate plate 7 are connected as a whole, thereby improving the water retaining quality and water retaining efficiency of the sluice and extending the service life of the sluice.

[0032] In a preferred embodiment, all components within the control assembly 53 can be made of steel, and the outer surface of the steel parts is coated or sprayed with a protective coating that can block river water erosion, thereby extending its service life and ensuring the water-retaining quality and efficiency of the sluice.

[0033] like Figures 2 to 5 As shown, as a preferred embodiment of the present invention, the fixing assembly 54 includes a fixing seat 541 and a fixing member 542, the fixing seat 541 is fixed on the guide rod 532, and the end surface of the fixing seat 541 close to the first fixing block 51 is provided with fixing members 542 that are consistent in position and number with the fixing groove 511, and the fixing member 542 cooperates with the fixing groove 511.

[0034] In this embodiment, the two guide rods 532 at the upper and lower ends of the first fixed block 51 drive their respective fixed seats 541 to move in the direction close to the first fixed block 51, and the two fixed seats 541 drive their respective fixing members 542 to move, and the fixing members 542 cooperate with the fixing groove 511 by moving. In this way, not only can the rotation angle of the first gate plate 1 and the second gate plate 7 be calibrated, but when the rotation angle of the first gate plate 1 and the second gate plate 7 does not meet the requirements, the fixing component 54 cannot cooperate with the fixing groove 511 normally, so that the staff can be warned and it is convenient for the staff to check the first gate plate 1, the second gate plate 7 and the regulating mechanism 3 in time to avoid the phenomenon of poor closure of the first gate plate 1 and the second gate plate 7, and ensure that the sluice can normally realize the water retaining function. It can also realize the connection between the first fixed block 51 and the second fixed block 52, so that the first gate plate 1 and the second gate plate 7 are connected as a whole.

[0035] In a preferred embodiment, the fixing member 542 preferably adopts a block structure that is compatible with the shape and specifications of the fixing groove 511, and the fixing member 542 can be fixed to the fixing seat 541 by welding or fixing bolts.

[0036] like Figure 2 and Figure 4As shown, as a preferred embodiment of the present invention, the bracket assembly 2 includes a V-shaped steel frame 21, a steel pillar 22 and a connecting kit 23. The V-shaped steel frame 21 is vertically distributed on the inner sides of the first gate plate 1 and the second gate plate 7, respectively. A connecting kit 23 is fixed to one end of the V-shaped steel frame 21. The connecting kit 23 is connected to the regulating mechanism 3. Steel pillars 22 are fixed between the two V-shaped steel frames 21 and between the two connecting kits 23.

[0037] In this embodiment, the V-shaped steel frame 21 is vertically distributed inside the first gate plate 1 and the second gate plate 7, ensuring that the gate plates can evenly distribute stress when subjected to force, reducing local stress concentration, and at the same time ensuring that the first gate plate 1 and the second gate plate 7 can withstand greater water pressure and external impact, ensuring that both can remain stable and reliable under extreme conditions, thereby improving the water retaining function of the sluice; The modular design of the bracket assembly 2 simplifies the installation and maintenance process, so that it can be pre-manufactured and assembled, and only simple connections are required during on-site installation, which reduces construction time and cost. In addition, the modular design also facilitates the inspection and replacement of components, improving the convenience and economy of maintenance of the sluice gate; The connection kit 23 preferably adopts a V-shaped frame structure formed by welding a plurality of steel plates, so that one end of the V-shaped steel frame 21 can extend into the interior thereof and be fixed.

[0038] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the regulating mechanism 3 includes a connecting steel plate 31, a connecting sleeve 32, a connecting steel column 33, a connecting assembly 34 and a hydraulic telescopic part 35. The connecting steel plate 31 is respectively installed on the two connecting kits 23 by fixing bolts, and a connecting sleeve 32 is welded on one side of the two connecting steel plates 31. The two ends of the connecting steel column 33 are respectively fixed in the two connecting sleeves 32. The middle part of the connecting steel column 33 is rotatably installed with a connecting assembly 34 connected to the hydraulic telescopic part 35. The hydraulic telescopic part 35 is fixed in the storage cavity 61.

[0039] In this embodiment, the hydraulic telescopic member 35 can drive the connecting steel column 33 to move outside the storage cavity 61 through hydraulic telescoping and cooperation with the connecting component 34. The connecting steel column 33 drives the connecting steel plate 31 to move outside the storage cavity 61 through the connecting sleeve 32. The connecting steel plate 31 drives the V-shaped steel frame 21 to move outside the storage cavity 61 through the connecting kit 23. The two V-shaped steel frames 21 can respectively drive one end of the first gate plate 1 and the second gate plate 7 to rotate around their respective second steel hinge seats 4, so that the other ends of the first gate plate 1 and the second gate plate 7 are precisely docked, thereby realizing the water-blocking function of the sluice. This flexibility enables the sluice system to respond quickly to different operating requirements. Whether it is water blocking or water releasing, it can be adjusted quickly, thereby improving the adaptability and response speed of the sluice.

[0040] In a preferred embodiment, the hydraulic telescopic member 35 preferably adopts a hydraulic telescopic structure composed of a hydraulic telescopic cylinder and a hydraulic telescopic rod.

[0041] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the connecting assembly 34 includes a first connecting sleeve 341, a second connecting sleeve 342, a pin 343 and a first steel hanger seat 344, the first connecting sleeve 341 and the second connecting sleeve 342 are both located on the outside of the middle of the connecting steel column 33, the first connecting sleeve 341 is fixed on the first steel hanger seat 344, the first steel hanger seat 344 is connected to the output end of the hydraulic telescopic member 35, a pin 343 is installed at one end of the first connecting sleeve 341, the pin 343 is rotatably connected to one end of the second connecting sleeve 342, and the other end of the second connecting sleeve 342 is fixedly connected to the first connecting sleeve 341 by bolts.

[0042] In this embodiment, the first connecting sleeve 341 and the second connecting sleeve 342 both adopt an arc-shaped plate structure, and the inner walls of both are installed with buffer pads that fit the outer wall of the connecting steel column 33. This can prevent the second connecting sleeve 342 from causing damage to the connecting steel column 33 during rotation, and the arc-shaped plate structure can provide a more uniform contact surface, thereby increasing the connection stability between the connecting steel column 33 and the first connecting sleeve 341 and the second connecting sleeve 342, so that the hydraulic telescopic part 35 can stably drive the connecting steel column 33 to move through the first steel hinge seat 344, the first connecting sleeve 341 and the second connecting sleeve 342.

[0043] The working principle of the present invention is: The hydraulic telescopic member 35 can drive the connecting steel column 33 to move outside the storage cavity 61 by hydraulic telescoping and cooperating with the connecting assembly 34. The connecting steel column 33 drives the connecting steel plate 31 to move outside the storage cavity 61 through the connecting sleeve 32. The connecting steel plate 31 drives the V-shaped steel frame 21 to move outside the storage cavity 61 through the connecting set 23. The two V-shaped steel frames 21 can respectively drive one end of the first gate plate 1 and the second gate plate 7 to rotate around their respective second steel hinge seats 4, so that the other ends of the first gate plate 1 and the second gate plate 7 are accurately docked, thereby realizing the water blocking function of the sluice. When the first gate plate 1 and the second gate plate 7 are closed, the two magnetic members 534 at the upper and lower ends of the first fixed block 51 can drive their respective mounting columns 533 to approach each other by attracting each other, and the two mounting columns 533 drive their respective mounting plates 531 to move toward the direction close to the first fixed block 51, and at this time, the spring 535 is in a compressed state; The two mounting plates 531 drive their respective fixing seats 541 to move toward the direction close to the first fixing block 51 through the guide rod 532, and the two fixing seats 541 drive their respective fixing members 542 to move, and the fixing members 542 cooperate with the fixing groove 511 by moving, so that not only the rotation angle of the first gate plate 1 and the second gate plate 7 can be calibrated, but also when the rotation angle of the first gate plate 1 and the second gate plate 7 does not meet the requirements, the fixing assembly 54 cannot normally cooperate with the fixing groove 511, so that the staff can be warned, so that the staff can check the first gate plate 1, the second gate plate 7 and the regulating mechanism 3 in time, avoid the phenomenon of poor closure of the first gate plate 1 and the second gate plate 7, ensure that the sluice can normally realize the water retaining function, and also realize the connection between the first fixing block 51 and the second fixing block 52, so that the first gate plate 1 and the second gate plate 7 are connected as a whole; At this time, the first gate plate 1 and the second gate plate 7 are connected as a whole with both sides of the concrete gate pier 6 through the fixed calibration mechanism 5 and the second steel hinge seat 4, which can not only improve the connection stability between the first gate plate 1 and the second gate plate 7, thereby improving the water blocking quality and water blocking efficiency of the sluice, but also avoid the first gate plate 1 and the second gate plate 7 from applying excessive pressure to the regulating mechanism 3 during the water blocking process, reduce the load of the regulating mechanism 3, and then reduce its failure rate, thereby extending the service life of the sluice as a whole; Similarly, when drainage is required, the connection between the fixed calibration mechanism 5 and the first gate plate 1 and the second gate plate 7 is first released, and then the first gate plate 1 and the second gate plate 7 are driven to rotate in opposite directions by the regulating mechanism 3, so that the first gate plate 1 and the second gate plate 7 can be rotated into the receiving chamber 61, thereby realizing the drainage function of the sluice gate; The above is the working principle of the river sluice used in this water conservancy project.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
