Abstract
Description
Technical Field
[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a highly durable water conservancy gate frame structure. Background Technology
[0002] Hydraulic gates are core control equipment in scenarios such as water conservancy projects, river management, water supply and drainage projects, and reservoir flood discharge. The gate frame structure is the core basic component for gate load bearing, lifting and guiding, and sealing and water stopping. Its structural stability and operational durability directly determine the overall service life of the gate and the operational safety of the water conservancy project.
[0003] In existing technologies, the opening and closing of hydraulic gates are mostly achieved using screw-type opening and closing mechanisms in conjunction with gate frame structures. However, the on-site working conditions of hydraulic engineering projects are complex, and the equipment is exposed to a humid, silty, and highly corrosive water environment for extended periods. Existing gate frames and their associated opening and closing structures suffer from the following intractable technical defects during long-term operation: Firstly, the lifting screw is difficult to protect and maintain, and its durability is insufficient: the transmission screw is exposed to the outdoor environment for a long time, and the spiral groove of the screw is prone to the accumulation of mud, scale, and microorganisms. This can not only cause thread engagement jamming and accelerated wear, but also, in severe cases, safety accidents such as gate jamming during opening and closing. At the same time, the lubrication of the screw mostly relies on manual application of grease. In a humid water environment, the grease is easily washed away by water flow and contaminated by mud and sand, making it impossible to achieve continuous and uniform lubrication. This makes the screw very susceptible to rust and pitting, effectively reducing the service life of the lifting mechanism.
[0004] Secondly, the poor synchronization of dual-point gates exacerbates structural wear: existing dual-point gates mostly use dual drives to control the lifting and lowering of screws on both sides, which easily leads to asynchronous lifting and lowering. This causes the gate to tilt during lifting and lowering, resulting in uneven wear between the gate and the guide frame and the sealing structure of the gate frame. This not only damages the water-stop sealing performance, but also aggravates the wear and deformation of the gate frame structure, further reducing the overall durability of the structure.
[0005] Third, the protection performance of core transmission components is insufficient: core components such as drive motors, worm gear transmission pairs, and gear transmission pairs are often directly exposed to outdoor humid, dusty, and corrosive environments, making them prone to problems such as motor short circuits due to moisture and transmission component corrosion and jamming. This results in a high equipment failure rate, high maintenance costs, and the need to completely disassemble the door frame structure to replace components, making maintenance difficult. Summary of the Invention
[0006] The main objective of this invention is to provide a highly durable hydraulic gate frame structure that can effectively solve the problems of low overall structural durability, high equipment failure rate, and high maintenance difficulty in existing hydraulic gate frame structures, such as easy adhesion of mud and scale to the lifting screw, insufficient continuous lubrication, asynchronous lifting of the two lifting points leading to uneven wear of the gate, and poor protection performance of the core transmission components.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A highly durable hydraulic gate frame structure includes a main body and a gate. The main body includes an integrated top support and two guide frames, as well as two adjusting mechanisms for raising and lowering the gate, a drive assembly for synchronously operating the two adjusting mechanisms, two lubrication assemblies, and two transmission assemblies. The adjusting mechanism includes a screw for raising and lowering and a self-cleaning assembly. The self-cleaning assembly lubricates and cleans the screw by cooperating with the lubrication and transmission assemblies. The drive and transmission assemblies are equipped with protective structures, and a protective frame is fixedly installed at the bottom of the top support for protection.
[0008] Preferably, the adjusting mechanism further includes a rotating frame rotatably connected to the top support via a bearing. The inner wall of the rotating frame is provided with an internal thread adapted to the screw. The rotating frame and the screw are connected by a threaded transmission. A worm gear is fixedly sleeved on the outer wall of the rotating frame. The bottom of the screw is fixedly connected to the top of the gate via a hinge seat.
[0009] Preferably, the drive assembly includes a motor for driving the two rotating frames to rotate synchronously, a rotating shaft, and two worm gears. The two worm gears are coaxially fixed to the outer wall of the rotating shaft, and the two worm gears are respectively connected to two worm wheels for transmission, forming a worm gear transmission. One end of the rotating shaft is coaxially fixedly connected to the output end of the motor through a coupling.
[0010] Preferably, the self-cleaning assembly includes a brush roller, a rotating rod, a fixed frame, and a driven frame for cleaning the screw. The outer brush surface of the brush roller is in close contact with the helical section of the screw, and the length of the brush roller covers the threaded engagement section of a single stroke of the screw. The driven frame is coaxially and fixedly connected to the bottom of the rotating frame. The fixed frame is horizontally and fixedly sleeved on the outer wall of the driven frame, and the extended end of the fixed frame is rotatably connected to the rotating rod through a bearing. The brush roller and the transmission gear are coaxially and fixedly installed on the outer wall of the rotating rod, with the transmission gear located above the brush roller.
[0011] Preferably, the transmission assembly further includes a fixed circular frame detachably mounted on the bottom of the top bracket, a plurality of positioning seats fixedly connected to the fixed circular frame, and an annular rack fixedly mounted on the inner wall of the fixed circular frame and meshing with the gear. The fixed circular frame is coaxially sleeved on the outside of the rotating frame and the driven frame, and the transmission gear meshes with the inner ring tooth surface of the annular rack.
[0012] Preferably, the lubrication assembly includes a fixed cylinder fixedly installed on the top of the rotating frame, an elastic lubricating sponge installed inside the fixed cylinder, and an oil inlet pipe fixedly connected to and communicating with the fixed cylinder. A circular baffle is fixedly installed on the top of the screw, and the circular baffle is in contact with the inner wall of the fixed cylinder. The outer wall of the circular baffle is slidably in contact with the inner wall of the fixed cylinder, which is used to limit the downward limit stroke of the screw and prevent impurities from falling into the fixed cylinder, thereby improving the protective effect.
[0013] Preferably, the drive assembly further includes a heat sink fixedly mounted on the top of the top bracket, and a cover detachably mounted on the top of the heat sink. The motor is fixedly mounted inside the cover, and one of the worm gears is rotatably connected to the inner wall of the cover. The transmission assembly further includes a frame cover detachably mounted on the bottom of the fixed circular frame. The frame cover is coaxially sleeved on the outside of the screw. The fixed circular frame and the frame cover form a closed protective cavity that covers the upper part of the transmission gear, the ring rack, and the self-cleaning component.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes the self-cleaning component's brush roller to rotate synchronously with the rotating frame, while simultaneously achieving rotation through the meshing of the transmission gear and the fixed annular rack. Throughout the screw lifting process, it comprehensively removes mud, scale, and microbial deposits from the screw's spiral grooves, preventing thread engagement jamming and abnormal wear. Simultaneously, the lubrication component's elastic lubricating sponge continuously and evenly applies grease to the screw's thread surface during lifting, isolating it from moisture and corrosive media, preventing screw rust, effectively reducing frictional loss in the threaded transmission, and significantly improving the service life and operational stability of the lifting mechanism.
[0015] 2. This invention utilizes a single-drive, dual-suspension-point synchronous transmission structure. A single motor drives the rotating shaft and two worm gears to rotate synchronously, which in turn drives the worm wheels on both sides and the rotating frame to rotate. This achieves absolute synchronous lifting and lowering of the two screws, ensuring that the gate does not tilt during lifting and lowering. It avoids uneven wear between the gate and the guide frame and the gate frame sealing structure, effectively protects the water-stop sealing parts and the guide structure, effectively reduces structural wear, and improves the long-term operational durability of the overall gate frame structure.
[0016] 3. This invention effectively improves the environmental tolerance and service life of core components by adopting a fully enclosed, graded protection structure. The motor and worm gear transmission pair of the drive component are built into a heat dissipation box, achieving waterproof and dustproof protection; the gear and rack pair of the transmission component are built into a closed cavity formed by a fixed circular frame and a frame cover, isolating them from mud, sand, and moisture; together with the protective frame at the bottom of the top bracket, the core drive and transmission components are fully enclosed and graded protected, preventing components from getting damp and corroded, and from being blocked by mud and sand, effectively reducing the equipment failure rate, reducing maintenance frequency, and extending the service life of core components.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0020] like Figure 1-8 As shown, the present invention discloses a high-durability hydraulic gate frame structure, including a main body 1 and a gate 100. The main body 1 is an integrally cast reinforced concrete structure. The main body 1 includes a horizontally arranged top support 101 and two vertically symmetrically arranged guide frames 102. The two guide frames 102 are integrally fixed to the bottom of both ends of the top support 101. Vertical guide grooves are opened on the inner side of the two guide frames 102. The two side edges of the gate 100 are slidably engaged in the guide grooves to realize the guiding and limiting of the gate 100's lifting and lowering.
[0021] Two sets of symmetrically distributed adjusting mechanisms 3 are provided on the top support 101. The bottom of both sets of adjusting mechanisms 3 is connected to the top of the gate 100, which is used to drive the gate 100 to rise and fall along the guide frame 102. A drive assembly 2 is provided on the top of the top support 101. The drive assembly 2 is connected to the two sets of adjusting mechanisms 3 for driving the two adjusting mechanisms 3 to operate synchronously. Each set of adjusting mechanisms 3 is equipped with a lubrication assembly 5 and a transmission assembly 6. The adjusting mechanism 3 includes a screw 301 for lifting and lowering transmission and a self-cleaning assembly. The self-cleaning assembly, in cooperation with the lubrication assembly 5 and the transmission assembly 6, cleans and lubricates the thread surface of the screw 301 synchronously during the lifting and lowering process of the screw 301. The drive assembly 2 and the transmission assembly 6 are equipped with a closed protective structure. A protective frame 104 is also fixedly installed at the bottom of the top support 101. The protective frame 104 covers the outside of the adjusting mechanism 3 and the transmission assembly 6 to achieve outer protection.
[0022] Specifically, the adjusting mechanism 3 also includes a rotating frame 302 and a worm gear 303. The top support 101 has mounting holes adapted to the rotating frame 302. The rotating frame 302 is rotatably connected to the top support 101 through a double-row tapered roller bearing. The inner wall of the rotating frame 302 has an internal thread adapted to the external thread of the screw 301. The rotating frame 302 and the screw 301 form a screw-nut transmission pair. The worm gear 303 is fixedly sleeved on the outer wall of the rotating frame 302 through a flat key. The screw 301 vertically penetrates the rotating frame 302. The bottom of the screw 301 is fixedly connected to the top of the gate 100 through a fisheye hinge seat. By rotating the rotating frame 302, the screw 301 is driven to move vertically in a straight line along the axial direction, thereby driving the gate 100 to rise and fall.
[0023] Drive assembly 2 includes a motor 203, a rotating shaft 204, and two worm gears 205. A heat sink 201 is bolted to the top of the top bracket 101, and a cover 202 is detachably bolted to the top of the heat sink 201. The motor 203 is a waterproof brake motor, bolted to the inside of the cover 202. The rotating shaft 204 is horizontally positioned, with one end coaxially connected to the output end of the motor 203 via a coupling. The two worm gears 205... The 05 screws are coaxially fixed to the outer wall of the rotating shaft 204. The two worms 205 have the same helical direction, and each worm 205 meshes with one of the two worm wheels 303, forming a worm gear transmission pair. Both ends of the rotating shaft 204 are rotatably connected to the side wall of the heat sink 201 through deep groove ball bearings with sealing rings. The worm 205 at the end away from the motor 203 has its extended end rotatably connected to the inner wall of the cover 202 through a bearing, improving the rotational stability of the rotating shaft 204. The rotating shaft 204 is driven to rotate by the motor 203, which drives the two worms 205 to rotate synchronously, thereby synchronously driving the two worm wheels 303 and the rotating frame 302 to rotate synchronously, realizing the synchronous lifting and lowering of the two screws 301, ensuring that the gate 100 rises and falls without tilting.
[0024] The self-cleaning assembly includes a brush roller 307, a rotating rod 306, a fixed frame 305, and a driven frame 304. The driven frame 304 is an annular sleeve structure and is coaxially fixed to the bottom of the rotating frame 302 by bolts. The fixed frame 305 is an L-shaped bracket, with one end of the fixed frame 305 fixedly sleeved on the outer wall of the driven frame 304 and the other end of the fixed frame 305 extending vertically downward. The rotating rod 306 is vertically rotatably connected to the extended end of the fixed frame 305 through a bearing. The brush roller 307 is coaxially fixedly sleeved on the outer wall of the rotating rod 306. The brush roller 307 is made of wear-resistant nylon brush. The outer brush surface of the brush roller 307 is in close contact with the spiral section of the screw 301, and the end of the brush is embedded in the spiral groove of the screw 301. The transmission gear is coaxially fixedly sleeved on the top outer wall of the rotating rod 306, located above the fixed frame 305.
[0025] The transmission assembly 6 also includes a fixed circular frame 601, multiple positioning seats 602, and an annular rack 603. The fixed circular frame 601 is a cylindrical structure that runs vertically through the frame. The fixed circular frame 601 is coaxially sleeved on the outside of the rotating frame 302 and the driven frame 304. The multiple positioning seats 602 are uniformly welded and fixed to the top outer wall of the fixed circular frame 601 along the circumferential direction. The positioning seats 602 are fixedly connected to the bottom of the top bracket 101 by bolts to achieve the positioning and installation of the fixed circular frame 601. The annular rack 603... 03 is coaxially fixedly installed on the inner wall of the fixed circular frame 601. The transmission gear meshes with the inner ring tooth surface of the ring rack 603 for transmission. The bottom of the fixed circular frame 601 is detachably installed with an annular frame cover 604 by bolts. The frame cover 604 is coaxially sleeved on the outside of the screw 301. The fixed circular frame 601 and the frame cover 604 form a closed protective cavity, which covers the transmission gear, the ring rack 603, the driven frame 304, and the upper part of the fixed frame 305, thus achieving closed protection of the transmission pair.
[0026] When the rotating frame 302 rotates, it drives the driven frame 304 to rotate synchronously, which in turn drives the fixed frame 305, the rotating rod 306, and the brush roller 307 to revolve around the screw 301. At the same time, the transmission gear at the top of the rotating rod 306 rolls along the ring rack 603, driving the rotating rod 306 and the brush roller 307 to rotate on their own axis. This causes the brush roller 307 to rotate on its own axis while revolving around the screw, thus brushing away the deposits on the surface of the screw 301 and in the spiral groove from all directions, achieving real-time self-cleaning of the screw 301.
[0027] Lubrication assembly 5 includes a fixed cylinder 501, a lubricating sponge 502, and an oil inlet pipe 503. The fixed cylinder 501 is a cylindrical structure with an open bottom. The fixed cylinder 501 is coaxially fixed to the top of the rotating frame 302 by bolts. The lubricating sponge 502 is an annular oil-resistant and corrosion-resistant nitrile sponge. The lubricating sponge 502 is filled and installed inside the fixed cylinder 501. The screw 301 vertically penetrates the inner ring of the lubricating sponge 502 and the top end face of the fixed cylinder 501. The inner ring of the lubricating sponge 502 is interference-fitted with the outer wall of the screw 301. The oil inlet pipe 503... One end of the oil inlet pipe 503 is fixedly connected to the side wall of the fixed cylinder 501 and communicates with the inner cavity of the fixed cylinder 501. The other end of the oil inlet pipe 503 extends to the outside of the protective frame 104 and is equipped with an oil injection nozzle for adding grease into the fixed cylinder 501. A circular baffle is coaxially fixedly installed on the top of the screw 301. The diameter of the circular baffle is adapted to the inner diameter of the fixed cylinder 501. The outer wall of the circular baffle slides against the inner wall of the fixed cylinder 501 to limit the downward limit stroke of the screw 301 and prevent grease from overflowing from the top of the fixed cylinder 501.
[0028] During the process of the rotating frame 302 driving the screw 301 to rise and fall, the screw 301 and the lubricating sponge 502 generate relative axial movement. The lubricating sponge 502, which has absorbed grease, continuously and evenly applies grease to the threaded surface of the screw 301 to achieve continuous lubrication of the screw 301. At the same time, in conjunction with the cleaning of the brush roller 307, it ensures that the grease is free of impurities and applied evenly, thereby improving the lubrication effect.
[0029] In this embodiment, the main body 1 is formed by one-piece cast steel casting, which has strong structural rigidity and excellent resistance to water pressure impact and deformation. The screw 301 and the rotating frame 302 are made of 2Cr13 stainless steel, which has excellent corrosion resistance and wear resistance. The worm gear 303 is made of tin bronze, and the worm 205 is made of tempered alloy steel, which has smooth transmission and good wear resistance. All bearings are waterproof bearings with sealing rings, which are suitable for the humid working conditions of water conservancy projects.
[0030] Working principle: The high-durability hydraulic gate frame structure of the present invention is installed at the gate of a hydraulic project. The gate 100 slides in the groove of the guide frame 102. The adjustment mechanism 3 is driven by the drive component 2 to realize the lifting and lowering opening and closing of the gate 100. The specific working process is as follows: Gate opening process: The motor 203 is started and rotates forward. The motor 203 drives the rotating shaft 204 to rotate, which drives the two worm gears 205 to rotate synchronously. Through the meshing transmission between the worm gears 205 and the worm wheel 303, the two rotating frames 302 are synchronously driven to rotate synchronously in the top support 101. The rotating frame 302 and the screw 301 form a screw-nut transmission pair. The rotation of the rotating frame 302 drives the two screws 301 to move vertically upward synchronously, thereby pulling the gate 100 to rise smoothly along the slide groove of the guide frame 102, realizing the opening of the gate.
[0031] Gate closing process: The starting motor 203 reverses, and through the above transmission path, it drives the two rotating frames 302 to rotate synchronously in opposite directions, which in turn drives the two screws 301 to move vertically downward synchronously, pushing the gate 100 to descend smoothly along the guide frame 102, thereby closing the gate.
[0032] Throughout the entire opening and closing process of the aforementioned gate, self-cleaning and lubrication functions are simultaneously achieved: Self-cleaning function: While the rotating frame 302 rotates, it drives the driven frame 304 at the bottom to rotate synchronously, which in turn drives the fixed frame 305, rotating rod 306, and brush roller 307 to revolve around the screw 301. At the same time, the transmission gear at the top of the rotating rod 306 meshes with the annular rack 603 on the inner wall of the fixed circular frame 601. The transmission gear rolls along the annular rack 603, driving the rotating rod 306 and brush roller 307 to rotate at high speed. This causes the brush roller 307 to rotate synchronously while revolving around the screw 301. The brush of the brush roller 307 is embedded in the spiral groove of the screw 301, brushing away mud, scale, and impurities attached to the surface of the screw 301 and the spiral groove from all directions. This achieves real-time self-cleaning of the threaded surface of the screw 301 and prevents impurities from entering the threaded meshing surface and causing wear and jamming.
[0033] Continuous lubrication function: As the rotating frame 302 rotates, it drives the top fixed cylinder 501 to rotate synchronously. During the lifting and lowering process, the screw 301 and the lubricating sponge 502 inside the fixed cylinder 501 generate continuous axial relative motion. The elastic lubricating sponge 502, which has absorbed grease, continuously and evenly applies grease to the threaded surface of the screw 301, forming a uniform lubricating oil film on the threaded surface. This isolates moisture and corrosive media, preventing the screw 301 from rusting. At the same time, it effectively reduces the friction loss of the threaded drive, improves transmission efficiency and the service life of the components. Grease can be replenished into the fixed cylinder 501 periodically through the oil inlet pipe 503 without disassembling the structure, making maintenance convenient.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
