Description

Technical Field

[0001] This invention relates to the field of gate opening and closing equipment technology, and in particular to a gate opening and closing machine. Background Technology

[0002] Gates are key pieces of equipment used to cut off or block water flow, and are widely used in reservoirs, canals, sewage treatment plants, pumping stations, and other applications. The gate hoist is the actuator that controls the opening and closing of the gate. In actual operation, especially in waters with high sediment content or in still water environments, sediment deposition and siltation easily occur at the bottom and around the gate. Over a long period, the solid silt creates a tremendous enveloping force and static friction on the gate.

[0003] Currently, conventional technical solutions for solving the problem of siltation in gates are mainly divided into two categories. One is passive dredging, which uses external equipment such as dredgers, dredging robots, or high-pressure water guns to carry out dredging operations first. The other is enhanced opening and closing, which simply increases the power and torque of the gate hoist, attempting to rely on greater opening and closing force to forcibly overcome the resistance of silt and open the gate.

[0004] While both dredging methods are usable, they have obvious drawbacks. The former has problems such as long operation cycle, high cost and low efficiency, while the latter is very likely to cause serious damage to the gate sealing surface, resulting in water leakage after the gate is closed and loss of interception function. In more serious cases, it may cause structural damage such as gate deformation, damage to hoist gears or screws, resulting in huge maintenance costs and downtime losses. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a gate opening and closing mechanism to solve the problem that mud and sand are easily deposited and silted up at the bottom and around the gate, and that the gate sealing surface is easily severely damaged when the gate is opened, resulting in water leakage and loss of interception function after the gate is closed.

[0006] To achieve the above objectives, the present invention provides a gate opening and closing mechanism, comprising a frame body having a vertically arranged sliding channel; an opening and closing mechanism body fixedly connected to the frame body and having a vertically movable lifting end; a valve body slidably mounted within the sliding channel and fixedly connected to the lifting end; and an agitation assembly fixedly connected to the valve body, comprising several agitation units, each agitation unit having a rotatable agitation head at one end facing away from the valve body, the rotation direction of the agitation head being along the width direction of the valve body, a nozzle rod at one end facing away from the valve body, the nozzle rod being arranged along the centerline of the agitation head, a jet flow channel within the agitation unit, a nozzle opening at the end of the jet flow channel, the nozzle opening being located on the outer wall of the nozzle rod, and several agitation blocks at one end facing away from the valve body, the agitation blocks being arranged in a ring around the nozzle rod as the centerline, with agitation gaps between the agitation blocks, the jetting angle of the nozzle opening being able to pass through the agitation gaps.

[0007] In an optional example, the agitation unit includes an agitation housing fixedly connected to the valve body, an agitation head rotatably connected to the agitation housing, a nozzle rod extending into the agitation housing at one end facing towards the agitation housing, a water circuit rotary joint fixed inside the agitation unit, the water circuit rotary joint having a water circuit rotating end, a water circuit channel arranged along the nozzle rod axis at the end facing towards the agitation housing, one end of the water circuit channel being fixedly connected to the water circuit rotating end, and one end of the water circuit channel communicating with the nozzle orifice, the agitation housing being rotatably connected to the agitation head. The device is equipped with a driven gear, the center line of rotation of which coincides with the center line of rotation of the agitator head. An elastic abutment is fixed to one end of the driven gear facing towards the agitator head, and a drive locking ring is provided at one end of the elastic abutment facing towards the agitator head. A driven locking ring is fixed to one end of the agitator head facing towards the drive locking ring. The water channel, nozzle orifice, and water channel rotary joint combine to form a jet channel. The agitator unit includes a power mechanism for providing power, which is fixedly connected to the agitator housing and meshes with the driven gear.

[0008] In an optional example, the drive snap ring has a drive protrusion at one end facing closer to the driven snap ring, and the driven snap ring has a driven groove at one end facing closer to the drive snap ring that matches the drive protrusion.

[0009] In an optional example, the power mechanism includes a power motor fixedly connected to the agitator housing. A power bevel gear disposed inside the agitator housing is fixed on the output shaft of the power motor. A driven shaft is rotatably mounted inside the agitator housing. A driven bevel gear and a power gear are fixed on the outer wall of the driven shaft. The power gear meshes with the driven gear, and the power bevel gear meshes with the driven bevel gear.

[0010] In an optional example, the agitator housing is provided with a mounting groove, and a through groove is formed in the mounting groove that penetrates the agitator housing. A limit ring is fixed to the end of the agitator head facing closer to the agitator housing. A rotary bearing is fixed in the mounting groove, and the limit ring is fixedly connected to the inner ring of the rotary bearing.

[0011] In an optional example, a first bearing housing and a second bearing housing are fixed inside the agitator housing, the driven gear is fixedly connected to the first bearing housing via a bearing connection, and the driven shaft is fixedly connected to the second bearing housing via a bearing connection.

[0012] In an optional example, a connecting bracket is fixed inside the agitator housing, and the connecting bracket is fixedly connected to the water channel rotary joint.

The main support column has a through groove that matches the cutting axis, and the ends of the support plates have arc-shaped portions that face away from the valve body.

[0016] The beneficial effects of this invention are as follows: through the synergistic effect of mechanical agitation and hydraulic flushing of the agitator, silt deposits at the bottom and around the valve can be actively removed before the valve is opened, avoiding the technical problem of gate jamming and inability to open and close normally due to silt accumulation. At the same time, since the solid silt layer has been liquefied or removed before the valve is opened, the static friction force that needs to be overcome when the valve is started is greatly reduced, reducing the risk of damage to the valve sealing surface or even valve body deformation caused by the traditional forced opening and closing of silted gates. This also avoids equipment damage caused by overload, extends the service life of the entire device, and the agitator is integrated with the valve body, eliminating the need for additional independent silt removal equipment. The operation process can be linked with the gate control system to achieve automated operation, improving work efficiency and intelligence. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] In one embodiment, please refer to Figures 1 to 2 As shown, the present invention provides a gate opening and closing mechanism, comprising: a frame body 1, an opening and closing mechanism body 2, a valve body 3, and an agitator assembly.

[0034] The frame body 1 has a vertically arranged sliding channel 101. The frame body 1 is usually welded from steel profiles and is fixedly installed in water conservancy channels or pipe openings to guide the raising and lowering of the valve body 3.

[0035] The hoist body 2 is fixedly connected to the frame body 1 by bolts or welding, and has a lifting end 21 that can move vertically. The lifting end 21 adopts a screw structure, and the hoist body 2 can drive the lifting end 21 to move vertically by electric or manual means.

[0036] The valve body 3 is slidably mounted within the sliding channel 101 and is fixedly connected to the lifting end 21 via a pin connection. A guide wheel is bolted to the side wall of the valve body 3, and the guide wheel is slidably mounted within the sliding channel 101.

[0037] The agitation assembly is fixedly connected to the valve body 3 and includes several agitation units 4. The agitation unit 4 is provided with a rotatable agitation head 41 at one end facing away from the valve body 3. The rotation direction of the agitation head 41 is set along the width direction of the valve body 3. The agitation head 41 is provided with a nozzle rod 42 at one end facing away from the valve body 3. The nozzle rod 42 is set along the center line of the agitation head 41. The agitation unit 4 has a jet flow channel. The end of the jet flow channel has a nozzle orifice 402. The nozzle orifice 402 is opened on the outer wall of the nozzle rod 42. The agitation head 41 is provided with several agitation blocks 43 at one end facing away from the valve body 3. The agitation blocks 43 are arranged in a ring around the nozzle rod 42. There is an agitation gap between the agitation blocks 43. The jet angle of the nozzle orifice 402 can pass through the agitation gap. The agitator 43 has a rectangular, trapezoidal, or blade-shaped cross-section, used to cut and agitate the deposited sludge during rotation; the jet channel is connected to an external high-pressure water pump via a pipeline connection; the agitator 41 rotates along the width of the valve, effectively cleaning the area directly below the valve that is most prone to sludge accumulation; the nozzle 402 is precisely aligned with the agitation gap, ensuring that the high-pressure water flow can maximize its effect on the agitated sludge, resulting in high energy utilization; the agitator assembly has a compact structure, making it suitable not only for new projects but also for upgrading existing gates, with broad application prospects.

[0038] When the gate needs to be opened, the agitation assembly is first activated. An external high-pressure water pump injects high-pressure water into the jet channel and sprays it out at high speed from the nozzle 402. The drive motor drives the agitator head 41, nozzle rod 42, and agitator block 43 to rotate together along the width of the valve. The high-speed rotating agitator block 43, like a rotating blade, breaks up and crushes the sludge layer that has hardened at the bottom and around the valve. The high-pressure water jet from the agitation gap further impacts and dilutes the broken sludge, forming a mud-water mixture. After a period of time, the hoist body 2 is activated to lift the valve body 3. During this process, the liquefied sludge is more easily washed away by the water flow, which greatly reduces the resistance to valve opening and effectively prevents problems such as jamming, damage to the sealing surface, and overload of the hoist caused by sludge accumulation.

[0039] In summary, this example utilizes the combined synergistic effect of mechanical agitation and hydraulic flushing of the agitator to proactively remove silt deposits from the bottom and surrounding area of ​​the valve before opening. This avoids the technical challenges of gate jamming and inability to open or close normally due to silt accumulation. Furthermore, since the solid silt layer is liquefied or removed before opening, the static friction force required to overcome during valve startup is significantly reduced. This mitigates the risk of damaging the valve sealing surface or even deforming the valve body caused by forcibly opening and closing clogged gates, preventing equipment damage due to overload and extending the service life of the entire system. Moreover, the agitator is integrated with the valve body 3, eliminating the need for additional independent silt removal equipment. The operation process can be linked with the gate control system for automated operation, improving work efficiency and intelligence.

[0040] In an optional example, please refer to Figures 1 to 6As shown, the agitation unit 4 includes an agitation housing 31 fixedly connected to the valve body 3. An agitation head 41 is rotatably connected to the agitation housing 31. A nozzle rod 42 extends into the agitation housing 31 at one end, with one end facing closer to the agitation housing 31. A water channel rotary joint 32 is fixedly installed inside the agitation unit 4. The water channel rotary joint 32 has a water channel rotating end 321. A water channel 421, arranged along the axis of the nozzle rod 42, is opened at the end of the nozzle rod 42 facing closer to the agitation housing 31. One end of the water channel 421 is fixedly connected to the water channel rotating end 321, and the other end of the water channel 421 communicates with the nozzle orifice 402. The agitation housing 31 is connected to the agitation head 41 via a rotary joint. The agitator 41 is equipped with a driven gear 33, the rotation center line of which coincides with the rotation center line of the agitator 41. An elastic contact piece 34 is fixed to one end of the driven gear 33 facing closer to the agitator 41. A drive locking ring 35 is provided to one end of the elastic contact piece 34 facing closer to the agitator 41. A driven locking ring 36 is fixed to one end of the agitator 41 facing closer to the drive locking ring 35. The water channel 421, the nozzle 402 and the water channel rotary joint 32 are combined to form a jet channel. The agitator 4 includes a power mechanism for providing power. The power mechanism is fixedly connected to the agitator housing 31 and meshes with the driven gear 33.

[0041] When the gate needs to be opened, the external high-pressure water pump is first started. High-pressure water is delivered to the rotating nozzle rod 42 through the water circuit rotary joint 32 and sprayed out from the nozzle port 402. At the same time, the power mechanism is started, and torque is transmitted through the meshing of the drive gear and driven gear 33. The torque is transmitted to the stirring head 41 through the elastic contact plate 34, the drive locking ring 35 and the driven locking ring 36, causing it to rotate together with the nozzle rod 42 and the stirring block 43. The rotating stirring block 43 cuts and breaks up the hardened silt, and the high-pressure water jet precisely sprayed from the stirring gap immediately impacts and liquefies the broken silt. After a period of time, the gate hoist body 2 is then started to lift the valve to complete the gate opening operation.

[0042] Specifically, in this example, the torque is transmitted through the elastic contact plate 34, which not only ensures the stable cutting ability of the agitator 43, but also has the ability to compensate for errors and buffer impacts, preventing large debris from jamming the agitator head 41, thus improving the reliability and service life of the transmission system. Furthermore, the high-pressure water flow is delivered through the water circuit rotary joint 32, which enables the high-pressure water flow to be continuously and stably delivered to the rotating spray bar, ensuring the continuous operation capability of the dredging function.

[0043] In an optional example, please refer to Figures 1 to 7As shown, the drive retaining ring 35 has a drive protrusion 351 at one end facing closer to the driven retaining ring 36, and the driven retaining ring 36 has a driven groove 361 that matches the drive protrusion 351 at one end facing closer to the drive retaining ring 35. The drive protrusion 351 has a wedge-shaped end face one, and the driven groove 361 has a wedge-shaped end face two that matches the wedge-shaped end face one.

[0044] Specifically, when the torque of the drive ring 35 is too large, the combination of wedge end face one and wedge end face two can generate an oblique force, causing the drive protrusion 351 to disengage from the driven groove 361, ensuring stable operation even under heavy load and harsh working conditions.

[0045] In an optional example, please refer to Figures 1 to 9 As shown, the power mechanism includes a power motor 37 fixedly connected to the agitator housing 31 by bolts. A power bevel gear 38, disposed within the agitator housing 31, is fixedly mounted on the output shaft of the power motor 37. A driven shaft 39 is rotatably mounted within the agitator housing 31. A driven bevel gear 310 and a power gear 311 are fixedly connected to the outer wall of the driven shaft 39 by a key. The power gear 311 meshes with the driven gear 33, and the power bevel gear 38 meshes with the driven bevel gear 310. The power motor 37 is fixed to the outer wall of the agitator housing 31, and its output shaft extends into the agitator housing 31. When the power motor 37 operates, its output shaft drives the power bevel gear 38 to rotate, which in turn drives the driven bevel gear 310 to rotate. The driven bevel gear 310 then drives the driven shaft 39 to rotate, which in turn drives the power gear 311 to rotate, and finally, the power gear 311 drives the driven gear 33 to rotate.

[0046] Specifically, the power mechanism in this example adopts a combination transmission scheme of bevel gears and cylindrical gears, which means that the power motor 37 does not have to be coaxially installed with the agitator head 41. Instead, it can flexibly select the optimal and most space-saving installation position according to the spatial layout inside the agitator housing 31, which greatly enhances the design flexibility and the compactness of the whole machine. It is very suitable for harsh environments with limited underwater installation space.

[0047] In an optional example, please refer to Figures 1 to 9 As shown, the stirring housing 31 has a mounting groove 3101, and a through groove 3102 extending through the stirring housing 31. A limiting ring 312 is fixed to the end of the stirring head 41 facing closer to the stirring housing 31 by bolts. A rotating bearing 313 is inserted and fixed into the mounting groove 3101, and the limiting ring 312 is fixedly connected to the inner ring of the rotating bearing 313. The limiting ring 312 has a limiting flange extending away from its centerline, and the limiting flange is inserted into the inner ring of the rotating bearing 313.

[0048] Specifically, this example reduces the manufacturing difficulty and cost of the stirring unit 4 by reducing the structure of the stirring shell 31 and the stirring head 41, and facilitates the maintenance of the stirring unit 4.

[0049] In an optional example, please refer to Figures 1 to 10 As shown, a first bearing housing 314 and a second bearing housing 315 are fixed inside the agitator housing 31 by bolt connection. An extension protrusion ring 331 is provided on the driven gear 33. The extension protrusion ring 331 is fixedly connected to the first bearing housing 314 by bearing connection. The driven rotating shaft 39 is fixedly connected to the second bearing housing 315 by bearing connection.

[0050] Specifically, in this example, the driven gear 33 and the driven shaft 39 are fixed by the combination of the first bearing housing 314 and the second bearing housing 315, which effectively reduces the installation difficulty of the driven gear 33 and the driven shaft 39 and facilitates the disassembly and assembly of the stirring unit 4.

[0051] In an optional example, please refer to Figures 1 to 10 As shown, a connecting bracket 316 is fixed inside the agitator housing 31. The two ends of the connecting bracket 316 are fixedly connected to the agitator housing 31 by bolts. The connecting bracket 316 is also fixedly connected to the water channel rotary joint 32 by bolts.

[0052] Specifically, in this example, the water circuit rotary joint 32 is fixed by a leveling bracket, which effectively reduces the installation difficulty of the water circuit rotary joint 32 and facilitates the disassembly and assembly of the agitation unit 4.

[0053] In an optional example, please refer to Figures 1 to 11 As shown, the elastic contact piece 34 includes a positioning ring body 341, within which several extensions 342 are provided. A drive engagement ring 35 has a plug ring 317 fixed to one end facing the positioning ring body 341. The outer wall of the plug ring 317 has a snap-fit ​​slot 3171 that matches the extensions 342. Bolt holes are provided on the extensions 342, allowing the plug ring 317 to be fixedly connected to the drive engagement ring 35 via bolts. The positioning ring body 341 is fixedly connected to the driven gear 33 via bolts.

[0054] Specifically, this example reduces the installation difficulty of the elastic contact piece 34 by optimizing its structure, making it easier to disassemble and maintain.

[0055] In an optional example, please refer to Figures 1 to 11As shown, a cutting shaft 5 is mounted on the valve body 3 via a bearing connection, and a cutting telescopic cylinder 6 is mounted on the valve body 3 via a rotating shaft connection. The centerline of the cutting shaft 5 is set along the length of the valve body 3. A drive arm 7 and several sets of cutting components 8 are fixed to the outer wall of the cutting shaft 5 via bolts. The telescopic end of the cutting telescopic cylinder 6 is fixedly connected to the end of the drive arm 7 via a rotating shaft connection. When the cutting telescopic cylinder 6 is working, the telescopic end of the cutting telescopic cylinder 6 drives the drive arm 7 to rotate, the drive arm 7 drives the cutting shaft 5 to rotate, and the cutting shaft 5 drives the cutting components 8 to rotate, causing the cutting components 8 to rotate in a direction away from the valve body 3. This allows them to cut, tear, and remove flexible obstacles such as ropes, weeds, and fishing nets entangled around the valve body 3, clearing obstacles for the normal opening and closing of the valve.

[0056] Specifically, this example, through the design of the cutting component, makes it applicable to waters with abundant aquatic plants, frequent fishing activities, or a lot of garbage. It can effectively deal with the entanglement and jamming problem that traditional gates cannot handle, expanding the application scenarios of the present invention. Furthermore, the cutting function is directly integrated into the valve body 3, eliminating the need for additional boats or divers for external cleaning, thus realizing the automation and intelligence of underwater obstacle removal.

[0057] In an optional example, please refer to Figures 1 to 12 As shown, the cutting component 8 includes several support plates 81 that are spaced apart from each other, are parallel to each other and are spaced a certain distance apart, forming a channel for capturing and cutting obstacles.

[0058] The support pieces 81 are fixed together by welding. The main support 82 and several auxiliary support 83 connect the support pieces 81 into a sturdy whole frame, which greatly enhances the structural strength and rigidity of the entire cutting piece 8 and prevents it from deforming during cutting.

[0059] The main support 82 has a through groove 821 that matches the cutting shaft 5, and the end of the support plate 81 has an arc-shaped portion 811 facing away from the valve body 3. The arc-shaped portion 811 can be a smooth curved surface or a hook-shaped structure with a cutting edge.

[0060] Specifically, this example uses the cooperation of support plate 81, main support column 82 and auxiliary support column 83 to form a high-strength and high-rigidity cutting component 8, which enables the cutting component 8 to withstand huge cutting forces without structural deformation or damage, thus ensuring the service life of the cutting component 8.

[0061] In summary, this valve, through the combined synergistic effect of mechanical agitation and hydraulic flushing of the agitation component, can proactively remove silt deposits from the bottom and surrounding area of ​​the valve before opening. This avoids the technical problem of gate jamming and inability to open and close normally due to silt accumulation, achieving automated operation and improving the working efficiency and intelligence level of the gate opening and closing mechanism. Furthermore, the torque transmission through the elastic contact plate 34 not only ensures the stable cutting ability of the agitation block 43 but also has the ability to compensate for errors and buffer impacts, preventing large debris from jamming the agitation head 41, thus improving the reliability and service life of the transmission system. At the same time, the addition of a cutting component makes it suitable for waters with abundant aquatic plants, frequent fishing activities, or a lot of garbage, effectively handling the entanglement jamming problem that traditional gates cannot handle, expanding the application scenarios of this invention, and realizing the automation and intelligence of underwater obstacle removal.
