Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, and in particular to a gate structure for water conservancy projects. Background Technology
[0002] Water conservancy gates are key equipment for water resource regulation, and their performance directly affects the safety and efficiency of water conservancy facilities. Traditional gates are mostly made of steel or concrete structures and are driven by hoists to lift or rotate. In recent years, with the development of materials science and automation technology, lightweighting, corrosion resistance and intelligent control of gates have become research focuses.
[0003] Existing gates generally suffer from insufficient impact resistance, leading to deformation or breakage. In waters with high sediment content or high flow velocity, gate wear and failure rates increase significantly.
[0004] Therefore, this application provides a gate structure for hydraulic engineering. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a gate structure for hydraulic engineering, which overcomes the deficiencies of existing technologies and aims to solve the problem that existing gates generally have insufficient impact resistance, leading to gate deformation or breakage, and significantly increasing gate wear and failure rate in waters with high sediment content or high flow velocity.
[0006] To achieve the above objectives, this application provides the following technical solution: a gate structure for water conservancy projects, comprising two sets of columns, each set of columns having a crossbeam fixedly installed at its top, a gate leaf assembly between the two sets of columns, the gate leaf assembly including a gate frame, the gate frame being slidably connected between the two sets of columns, a driving mechanism being provided between the top of the gate frame and the crossbeam, two sets of rotating shafts being rotatably connected to the middle of the gate frame, upper and lower gate leaves being fixedly installed on the outer surfaces of the two sets of rotating shafts respectively, two sets of reciprocating motors being fixedly installed inside the gate frame, the output ends of the two sets of reciprocating motors being fixedly installed at one end of the two sets of rotating shafts respectively, the upper and lower gate leaves being double-layer steel plate sandwich structures, and the interior of the upper and lower gate leaves being filled with polyurethane foam.
[0007] By adopting the above technical solution, the gate leaf assembly is driven to move up and down by the drive mechanism. When the water flow velocity is low, the reciprocating motor located at the bottom drives the rotating shaft to rotate, thereby adjusting the angle of the lower gate leaf. When the water flow velocity is high, two sets of reciprocating motors are activated to drive the rotating shaft to rotate, thereby adjusting the angle of both the upper and lower gate leaves. The opening degree within the gate frame can be flexibly adjusted according to the actual water flow conditions, which is beneficial for adapting to waters with different flow velocities. At the same time, both the upper and lower gate leaves are double-layer steel plate structures, which improves the strength of the upper and lower gate leaves. Combined with polyurethane foam, it has good buffering performance, which can effectively absorb the impact energy of the water flow, enhance the impact resistance of the gate leaf assembly, and improve the deformation resistance and fracture resistance of the gate leaf assembly.
[0008] As a preferred technical solution of this application, the flow guiding mechanism includes two sets of extension plates, which are symmetrically installed on the outer wall of the door frame. A base plate is fixedly connected between the two sets of extension plates. Several sets of partition plates are installed on the top of the base plate, which divide the space between the two sets of extension plates into several sets of flow guiding cavities. Two sets of flow guiding blades are installed in the flow guiding cavities, and the flow guiding blades are fixedly installed with the adjacent extension plates or partition plates.
[0009] By adopting the above technical solution, when the water flows between the two sets of extension plates, the local flow velocity is reduced by several sets of guide cavities. The guide leaf plays a certain guiding role for the water flow. The guide leaf is made of 304 stainless steel and is bent to slow down the water flow and reduce the direct impact of the water flow on the door leaf assembly, which greatly reduces the possibility of wear and failure of the door leaf assembly.
[0010] As a preferred technical solution of this application, the driving mechanism includes two sets of hydraulic cylinders, both sets of hydraulic cylinders are fixedly installed on the top of the crossbeam, the piston end of the hydraulic cylinder passes through the interior of the crossbeam and is fixedly installed with a connecting block, and the bottom end of the connecting block is fixedly installed on the top of the door frame.
[0011] By adopting the above technical solution, the piston end of the hydraulic cylinder extends and retracts, causing the door frame to slide up and down between the two sets of columns 1, thereby realizing the lifting and lowering operation of the door leaf assembly.
[0012] As a preferred technical solution of this application, two sets of sealing covers are fixedly installed on the inner wall of the door frame. The two sets of sealing covers cover two sets of reciprocating motors respectively. A through hole matching the rotating shaft is opened in the middle of the sealing cover.
[0013] By adopting the above technical solution, two sets of sealing covers are used to waterproof and seal the two sets of reciprocating motors, thereby improving the protection effect of the reciprocating motors.
[0014] As a preferred technical solution of this application, the outer walls of both the upper and lower door leaves are provided with dovetail grooves, and a sealing strip is engaged inside the dovetail grooves.
[0015] By adopting the above technical solution, when the upper and lower door leaves are closed, the sealing strip is pressed and in close contact with the door frame. The sealing strip is made of fluororubber, which is conducive to adapting to the slight deformation of the door frame and minimizing the occurrence of leakage.
[0016] As a preferred technical solution of this application, guide blocks are fixedly installed on both sides of the door frame, and guide grooves are opened on the opposite surfaces of the two sets of columns, with the guide blocks slidably connected to the adjacent guide grooves.
[0017] By adopting the above technical solution, the door frame is guided by the guide block sliding in the guide groove during the lifting and lowering process, thereby improving the stability of the door frame during lifting and lowering.
[0018] As a preferred technical solution of this application, a solar panel is fixedly installed at the top of the crossbeam, the solar panel is located between the two sets of hydraulic cylinders, a battery compartment is fixedly installed inside the crossbeam, a storage battery is installed inside the battery compartment, and the solar panel is electrically connected to the storage battery.
[0019] By adopting the above technical solution, solar energy is collected and converted into electrical energy through solar panels and stored in the battery in the battery compartment to power the electrical equipment of this device, thereby improving economic efficiency.
[0020] As a preferred technical solution of this application, a controller is fixedly installed on one side of one set of columns, and a base is fixedly installed at the bottom of both sets of columns, with a weighted seat fixedly installed at the bottom of the base.
[0021] By adopting the above technical solution, the controller facilitates the operation of the device by the staff, and the base and weighted seat increase the stability of the column and improve the device's resistance to water flow impact.
[0022] The beneficial effects of this application are:
[0023] 1. The gate leaf assembly is driven up and down by a drive mechanism. When the water flow velocity is low, the reciprocating motor located at the bottom drives the rotating shaft to rotate, causing the lower gate leaf to adjust its angle. When the water flow velocity is high, two sets of reciprocating motors drive the rotating shaft to rotate, causing both the upper and lower gate leaves to adjust their angles. The opening degree within the gate frame can be flexibly adjusted according to the actual water flow conditions, which is beneficial for adapting to waters with different flow velocities. At the same time, both the upper and lower gate leaves are double-layer steel plate structures, which improves their strength. Combined with polyurethane foam, they have good buffering performance, which can effectively absorb the impact energy of the water flow, enhance the impact resistance of the gate leaf assembly, and improve the deformation resistance and fracture resistance of the gate leaf assembly.
[0024] 2. When the water flows between the two sets of extension plates, it is diverted by several sets of guide cavities to reduce the local flow velocity. The guide blades, which are made of 304 stainless steel, guide the water flow and reduce the direct impact of the water flow on the door leaf assembly, thus greatly reducing the possibility of wear and failure of the door leaf assembly.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0032] Reference Figure 1-5 A gate structure for hydraulic engineering includes two sets of columns 1, each with a crossbeam 2 fixedly installed at its top. A gate leaf assembly 4 is provided between the two sets of columns 1. The gate leaf assembly 4 includes a gate frame 401, which is slidably connected between the two sets of columns 1. A drive mechanism 3 is provided between the top of the gate frame 401 and the crossbeam 2. Two sets of rotating shafts 403 are rotatably connected to the middle of the gate frame 401. An upper gate leaf 5 and a lower gate leaf 6 are fixedly installed on the outer surfaces of the two sets of rotating shafts 403, respectively. An internal component is fixedly installed inside the gate frame 401. Two sets of reciprocating motors 402 are fixedly installed at one end of two sets of rotating shafts 403 respectively. The upper door leaf 5 and the lower door leaf 6 are both double-layer steel plate sandwich structures, and the interior of the upper door leaf 5 and the lower door leaf 6 are filled with polyurethane foam 12. The drive mechanism 3 includes two sets of hydraulic cylinders 301. Both sets of hydraulic cylinders 301 are fixedly installed at the top of the crossbeam 2. The piston end of the hydraulic cylinder 301 passes through the interior of the crossbeam 2 and is fixedly installed with a connecting block 302. The bottom end of the connecting block 302 is fixedly installed at the top of the door frame 401.
[0033] The door leaf assembly 4 is driven to move up and down by the drive mechanism 3. When the water flow velocity is low, the reciprocating motor 402 located below drives the rotating shaft 403 to rotate, thereby adjusting the angle of the lower door leaf 6. When the water flow velocity is high, the two sets of reciprocating motors 402 drive the rotating shaft 403 to rotate, thereby adjusting the angle of both the upper door leaf 5 and the lower door leaf 6. The opening and closing degree within the door frame 401 can be flexibly adjusted according to the actual water flow conditions, which is beneficial for adapting to waters with different flow velocities. At the same time, both the upper door leaf 5 and the lower door leaf 6 are double-layer steel plate structures, which improves the strength of the upper door leaf 5 and the lower door leaf 6. Combined with polyurethane foam 12, it has good buffering performance, which can effectively absorb the impact energy of the water flow, enhance the impact resistance of the door leaf assembly 4, and improve the deformation resistance and fracture resistance of the door leaf assembly 4. The piston end of the hydraulic cylinder 301 extends and retracts, causing the door frame 401 to slide up and down between the two sets of columns 1, thereby realizing the lifting and lowering operation of the door leaf assembly 4.
[0034] Reference Figure 2-5The flow guiding mechanism 7 includes two sets of extension plates 701, which are symmetrically installed on the outer wall of the door frame 401. A base plate 702 is fixedly connected between the two sets of extension plates 701. Several sets of partition plates 703 are installed on the top of the base plate 702. The partition plates 703 divide the space between the two sets of extension plates 701 into several sets of flow guiding cavities 704. Two sets of flow guiding blades 705 are installed at the flow guiding cavities 704. The flow guiding blades 705 are fixedly installed with the adjacent extension plates 701 or partition plates 703. Two sets of sealing covers 8 are fixedly installed on the inner wall of the door frame 401. The two sets of sealing covers 8 cover the two sets of reciprocating motors 402 respectively. A through hole 9 matching the rotating shaft 403 is opened in the middle of the sealing cover 8.
[0035] When the water flows between the two sets of extension plates 701, the local flow velocity is reduced by several sets of guide cavities 704. The guide leaf 705 guides the water flow. The guide leaf 705 is made of 304 stainless steel and is bent to slow down the water flow and reduce the direct impact of the water flow on the door leaf assembly 4, which greatly reduces the possibility of wear and failure of the door leaf assembly 4. The two sets of sealing covers 8 provide waterproof sealing protection for the two sets of reciprocating motors 402, which improves the protection effect of the reciprocating motors 402.
[0036] Reference Figure 1-3 Both the upper door leaf 5 and the lower door leaf 6 have dovetail grooves 13 on their outer walls, and sealing strips 14 are snapped into the inside of the dovetail grooves 13. A solar panel 15 is fixedly installed at the top of the crossbeam 2, and the solar panel 15 is located between two sets of hydraulic cylinders 301. A battery compartment 16 is fixedly installed inside the crossbeam 2, and a storage battery is installed inside the battery compartment 16. The solar panel 15 is electrically connected to the storage battery. When the upper door leaf 5 and the lower door leaf 6 are closed, the sealing strip 14 is pressed and makes tight contact with the door frame 401. The sealing strip 14 is made of fluororubber, which is conducive to adapting to the slight deformation of the door frame 401 and minimizing the occurrence of leakage. The solar panel 15 collects solar energy and converts it into electrical energy, which is stored in the storage battery in the battery compartment 16 to power the electrical equipment of this device, thereby improving economic efficiency.
[0037] Reference Figure 1-4 Guide blocks 10 are fixedly installed on both sides of the door frame 401, and guide grooves 11 are opened on the opposite surfaces of the two sets of columns 1. The guide blocks 10 are slidably connected to the adjacent guide grooves 11. A controller 17 is fixedly installed on one side of one set of columns 1, and a base 18 is fixedly installed at the bottom of both sets of columns 1. A weighted seat 19 is fixedly installed at the bottom of the base 18. During the lifting and lowering process of the door frame 401, the guide blocks 10 slide in the guide grooves 11, which guides the door frame 401 during the lifting and lowering process and improves the stability of the door frame 401 during lifting and lowering. The controller 17 facilitates the operation of the device by the staff, and the base 18 and the weighted seat 19 increase the stability of the columns 1 and improve the device's resistance to water flow impact.
[0038] Working principle: The drive mechanism 3 drives the gate leaf assembly 4 to move up and down. When the water flow velocity is low, the reciprocating motor 402 located below drives the rotating shaft 403 to rotate, causing the lower gate leaf 6 to adjust its angle. When the water flow velocity is high, the two sets of reciprocating motors 402 drive the rotating shaft 403 to rotate, causing both the upper gate leaf 5 and the lower gate leaf 6 to adjust their angles. The opening degree within the gate frame 401 can be flexibly adjusted according to the actual water flow conditions, which is beneficial for adapting to waters with different flow velocities. At the same time, both the upper gate leaf 5 and the lower gate leaf 6 are double-layer steel plate structures, which improves the efficiency of the upper gate leaf 5 and the lower gate leaf 6. The strength of the lower door leaf 6, combined with the polyurethane foam 12, provides excellent buffering performance, effectively absorbing the impact energy of the water flow, enhancing the impact resistance of the door leaf assembly 4, and improving its resistance to deformation and fracture. When the water flows between the two sets of extension plates 701, it is diverted by several sets of guide cavities 704 to reduce the local flow velocity. The guide leaf 705, which is made of 304 stainless steel, plays a certain guiding role in the water flow, slowing down the water flow and reducing the direct impact of the water flow on the door leaf assembly 4, greatly reducing the possibility of wear and failure of the door leaf assembly 4.
[0039] The piston end of the hydraulic cylinder 301 extends and retracts, causing the door frame 401 to slide up and down between the two sets of columns 1, thereby realizing the lifting and lowering operation of the door leaf assembly 4. The two sets of sealing covers 8 provide waterproof sealing protection for the two sets of reciprocating motors 402, improving the protection effect of the reciprocating motors 402.
[0040] Meanwhile, when the upper door leaf 5 and the lower door leaf 6 are closed, the sealing strip 14 is pressed and in close contact with 401. The sealing strip 14 is made of fluororubber, which is conducive to adapting to the slight deformation of the door frame 401 and minimizing the occurrence of leakage. During the lifting and lowering process, the door frame 401 drives the guide block 10 to slide in the guide groove 11, which guides the door frame 401 during the lifting and lowering process and improves the stability of the door frame 401 during lifting and lowering.
[0041] In addition, solar energy is collected and converted into electrical energy by solar panel 15 and stored in the battery in battery compartment 16 to power the electrical equipment of this device, thus improving economic efficiency; the controller 17 facilitates operation of this device by staff, and the base 18 and weighted seat 19 increase the stability of column 1 and improve the device's resistance to water flow impact.
