Description

Technical Field

[0001] This application relates to the technical field of water conservancy engineering equipment, and more specifically, to a gate mechanism and an intake tower. Background Technology

[0002] Hydropower is the process of converting the kinetic energy of water flow into electrical energy. It is a renewable energy technology with advantages such as renewability, clean energy, stable power generation, economy, multifunctionality, controllability, and long lifespan. Hydropower facilities require intake towers with gates. The size of the gates is determined by the size of the intake and the terrain conditions, and they typically weigh tens of tons. A separate hydraulic hoist connects multiple detachable levers to the gate, which is then activated to lift the gate.

[0003] Current gate maintenance involves setting up a maintenance chamber in the gate slot near the inlet, allowing the gate to be lifted into the chamber for maintenance work, which is convenient. However, in reality, not only the gate needs maintenance, but also the connecting rods. The traditional chamber is not convenient for maintaining the connecting rods, requiring an additional maintenance team near the hydraulic hoist, or requiring maintenance personnel to perform maintenance multiple times, resulting in low maintenance efficiency.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0013] According to some embodiments of this application, the locking structure includes a clamping end, and after the locking platform passes through the clamping end, the clamping end clamps the pull rod and forms a locking connection with the locking platform.

[0014] According to one aspect of this application, a water intake tower is provided, the water intake tower including the gate mechanism as described above.

[0015] This application provides a gate mechanism and intake tower. The gate mechanism mainly includes a gate, a lifting assembly, and a disassembly assembly. The lifting assembly includes a hydraulic hoist and multiple tie rods, which are sequentially and detachably connected, with both ends of the tie rods detachably connected to the gate and the hydraulic hoist, respectively.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0032] like Figure 1 and Figure 2 As shown, in a first aspect, in some exemplary embodiments of this application, a gate mechanism is provided, which mainly includes: a gate 10, a lifting assembly 20, and a disassembly assembly 30; the lifting assembly 20 includes a hydraulic hoist 21 and a plurality of pull rods 22, the plurality of pull rods 22 being detachably connected in sequence, and the two ends of the plurality of pull rods 22 being detachably connected to the gate 10 and the hydraulic hoist 21, respectively; the disassembly assembly 30 includes a locking structure 31, a first lifting device 32, a second lifting device 33, and a storage structure 34, the locking structure 31 being locked to the pull rods 22 or the gate 10, and the first lifting device 32 and the second lifting device 33 being able to lift the pull rods 22 or the gate 10 and transfer them to the storage structure 34 for temporary storage and maintenance.

[0033] By coordinating the hydraulic hoist 21, the first lifting device 32, the second lifting device 33, and the locking structure 31, the function of sequentially disassembling the pull rod 22 and the gate 10 can be realized. This design not only simplifies the maintenance process of the gate 10 but also allows the disassembly, assembly, and maintenance of the gate 10 to be carried out in the same space. This means that the entire maintenance process can be completed by only one group of maintenance personnel, thereby effectively improving maintenance efficiency.

[0034] When maintenance is required on gate 10, hydraulic hoist 21 first lifts gate 10 and lever 22, disengaging them from their closed state. Then, a portion of lever 22 passes through locking structure 31, locking structure 31 with the remaining lever 22 or gate 10 to be disassembled, ensuring the locked portion does not move unexpectedly during disassembly. The first lifting device 32 and the second lifting device 33 work together to smoothly transfer the disassembled lever 22 to storage structure 34 for temporary storage and maintenance. This avoids instability caused by heavy levers 22 or gate 10 failing to form a complete lock after disassembly, thus ensuring operational safety and avoiding the inconvenience of multiple handling operations.

[0035] This application utilizes a hydraulic hoist 21 to lift the tie rod 22 and the gate 10. The hydraulic hoist 21 itself needs to lift the tie rod 22 and the gate 10 in daily operation, thus providing stronger stability and higher load-bearing capacity during the lifting stage. At the same time, this setup eliminates the need for large lifting equipment, removing the installation and dismantling steps of large lifting equipment, thereby shortening the preparation time and further improving maintenance efficiency.

[0036] At the same time, the first lifting equipment 32 and the second lifting equipment 33 are used to stably hoist the disassembled tie rod 22, ensuring that every step can be precisely controlled, avoiding the complex operation and safety hazards caused by the use of large lifting equipment.

[0037] Furthermore, the intake tower eliminates the need for separate maintenance space for gate 10, which not only simplifies the overall structure and reduces unnecessary space occupation but also enhances the stability and reliability of the building structure. This design makes the construction of water conservancy projects more convenient and management more efficient, bringing greater convenience and economy to the overall operation of water conservancy projects. By optimizing the structural layout, the overall design of the intake tower has been improved, not only meeting daily operational needs but also demonstrating greater flexibility and adaptability during the maintenance phase.

[0038] It should be noted that a gate slot 40 is provided inside the water intake tower. The gate slot 40 is used for the passage of the gate 10 and the pull rod 22. One end of the gate slot 40 is connected to the water inlet, and the other end is connected to the maintenance space 50. The hydraulic gate hoist 21 is located at the top of the maintenance space 50, and the disassembly assembly 30 is located inside the maintenance space 50.

[0039] Within the maintenance space 50, maintenance personnel can perform comprehensive and meticulous maintenance on the disassembled tie rod 22 and gate 10. Specifically, the maintenance personnel will first conduct a thorough inspection of the structure of the tie rod 22, assessing for any bending or twisting, and ensuring that its geometry conforms to standards. Furthermore, they will carefully inspect the degree of deformation at each connection point of the tie rod 22, confirming any wear or damage, and deciding whether to replace or repair relevant components based on the actual situation.

[0040] Maintenance of gate 10 includes a detailed inspection of its critical components. Maintenance personnel will check the water seal of gate 10 to ensure it is in good working order and free from leakage. Additionally, the condition of the auxiliary rollers will be assessed to confirm smooth rotation and the absence of wear or damage. Finally, maintenance personnel will also inspect the pressure surfaces of gate 10, including the gate leaf surface, for scratches, dents, or other damage, ensuring a tight seal against the gate frame when closed to prevent water leakage.

[0041] This series of inspections and maintenance procedures allows for the timely identification and resolution of potential problems, extending the service life of the gate mechanism and ensuring its stable and reliable operation in actual work. Throughout the maintenance process, maintenance personnel can complete all necessary inspections and repairs within the same space, significantly improving work efficiency and ensuring maintenance quality.

[0042] like Figure 1 and Figure 2 As shown in some exemplary embodiments of this application, the disassembly assembly 30 is provided with a vertically stacked first platform 35 and a second platform 36. A first lifting device 32 is fixedly mounted on the first platform 35, and a second lifting device 33 is slidably mounted on the first platform 35. A locking structure 31 is fixedly mounted on the second platform 36. A vertical space is formed between the first platform 35 and the second platform 36. Both platforms are located within the maintenance space 50 and can be used to place and disassemble a tie rod 22 of a certain length.

[0043] Specifically, the first platform 35 is mainly used for disassembling the tie rod 22 or gate 10 from the hydraulic hoist 21, and for connecting the tie rod 22 or gate 10 to the first lifting device 32 and the second lifting device 33. The second platform 36 is mainly used for disassembling the tie rod 22 and locking the tie rod 22 to be disassembled to ensure its stability during the disassembly process.

[0044] The fixed first lifting device 32 provides a reliable support point. After the tie rod 22 is disassembled, the unrestrained tie rod 22 may fall off during movement. Therefore, the first lifting device 32 is set up as a safety measure. The first lifting device 32 forms a tight connection with the tie rod 22 to ensure that it will not fall off, and its fixed connection position increases the stability of the overall system.

[0045] In contrast, the second lifting device 33 requires sliding to move the tie rod 22. During the movement of the tie rod 22 by the second lifting device 33, if it detaches, the first lifting device 32 can act as a protector, causing the tie rod 22 to deflect away from the second lifting device 33, thus avoiding the risk of impact to maintenance personnel at the second lifting device 33. This design not only improves the safety of the disassembly and assembly process but also ensures the smoothness and efficiency of the entire operation.

[0046] Through the reasonable layout of the first platform 35 and the second platform 36, and the synergistic effect of the first lifting equipment 32 and the second lifting equipment 33, this application provides a gate disassembly and maintenance scheme that is compact, easy to operate and safe and reliable, which greatly improves maintenance efficiency and safety.

[0047] like Figure 1 and Figure 2 As shown, in some exemplary embodiments of this application, the first lifting device 32 and the second lifting device 33 are located on opposite sides of the plane where the gate 10 is located, and the side of the first platform 35 facing the second platform 36 is provided with a sliding track 351 extending perpendicular to the plane where the gate 10 is located.

[0048] The sliding rail 351 is specifically designed for the second lifting device 33 to ensure its smooth sliding on the first platform 35, thereby accurately positioning and moving the tie rod 22. The sliding rail 351 extends along a plane perpendicular to the gate 10, allowing the second lifting device 33 to move flexibly in the vertical direction, facilitating the hoisting and disassembly of the tie rod 22 at different positions. The precise sliding direction and displacement facilitate coordination with the storage structure 34 to transfer the tie rod 22.

[0049] Understandably, sliding rails offer advantages such as precise positioning, smooth operation, high moving efficiency, and strong safety. They maintain linear motion throughout the movement, avoiding positioning deviations caused by unstable movement. Simultaneously, they reduce potential shaking during equipment movement, improving operational safety and reliability. This effectively avoids the risk of accidents due to equipment malfunction, enhancing the overall safety level of maintenance operations.

[0050] When the tie rod 22 needs to be disassembled, the second lifting device 33 moves along the sliding rail 351 to the designated position and connects with the tie rod 22. Then, the second lifting device 33 smoothly lifts the tie rod 22 and moves it along the sliding rail 351 to the predetermined position for disassembly. The entire process is not only efficient but also ensures the safety and stability of the tie rod 22 during movement. This provides strong support for the maintenance of the gate 10 in water conservancy projects, significantly improving the professionalism and efficiency of maintenance operations.

[0051] like Figure 5 and Figure 6 As shown in some exemplary embodiments of this application, the sliding rail 351 is an I-shaped rail, and the second lifting device 33 includes a first roller 331 and a second roller 332 arranged opposite each other, with the first roller 331 and the second roller 332 respectively located in opposite openings of the sliding rail 351. Specifically, the sliding rail 351 is an I-shaped rail, a design that ensures the stability and effectiveness of the second lifting device 33 during assembly and guarantees accuracy during movement.

[0052] The sliding track 351 adopts an I-beam structure, characterized by two parallel flanges and a central web. This structure not only provides sufficient strength and rigidity but also ensures the stability and guidance of the track. The second lifting device 33 includes a first roller 331 and a second roller 332 facing each other, located within opposite openings in the sliding track 351. This forms a clamping effect on the web, meaning the sliding track 351 and the two rollers mutually limit each other. The degree of freedom is the rolling direction of the rollers. Rolling causes rolling friction between the second lifting device 33 and the sliding track 351, which is relatively low compared to sliding friction. This is suitable for sliding applications, reduces wear, and effectively extends the service life.

[0053] like Figure 4 and Figure 5 As shown, in some exemplary embodiments of this application, both the first lifting device 32 and the second lifting device 33 are hand chain hoists. Hand chain hoists (also known as manual hoists or chain cranes) are widely used in a variety of industrial and construction environments, especially where heavy lifting and moving are required.

[0054] The main advantages of a hand-operated chain hoist are safety and reliability. It can be moved manually by operating the chain, requiring no electricity or other power source. Compared to large lifting equipment, its cost is relatively low; it can be installed once and reused without disassembly, remaining on the first platform 35. The hand-operated chain hoist's safety, reliability, economy, ease of operation, versatility, durability, environmental adaptability, and portability make it suitable for the maintenance and repair needs of gate 10 in water conservancy projects.

[0055] Specifically, such as Figure 5 and Figure 6 As shown in some exemplary embodiments of this application, the second lifting device 33 further includes a motor 333, a traction rope 334, a hook connector 335, a connecting chain 336, a hook 337, and a traction chain 338. The motor 333 is fixed on the base, and the base extends out two vertical plates, on which multiple first rollers 331 and second rollers 332 are respectively installed. The connection with the sliding track 351 is tighter, increasing the connection strength. At the same time, the vertical force is distributed through the gap between the two rollers, improving the force-bearing surface of the sliding track 351, thereby effectively increasing the load-bearing capacity and ensuring the structural stability during the sliding process.

[0056] The traction rope 334 and the hook connector 335 are used to drive the bottom connecting chain 336 and hook 337 to rise and fall. The traction rope 334 is connected to the output end of the motor 333. The hook connector 335 is used to connect multiple connecting chains 336 and hooks 337, which increases the number of hooks 337 to accommodate pull rods 22 of different weights. Understandably, the pull rod 22 requires high structural strength and is generally made of metal. It is typically four meters long and weighs between 600 kg and 1000 kg. Using multiple connecting chains 336 and hooks 337 increases the number of connection points to the pull rod 22, thereby increasing its structural stability.

[0057] The traction chain 338 is connected to the housing of the motor 333 and is used to apply tension to the second lifting device 33. In conjunction with the arrangement of the first roller 331 and the second roller 332, it enables the second lifting device 33 to slide, thereby driving the pull rod 22 located above it to slide. Both the traction chain 338 and the connecting chain 336 are metal chains, which increases the structural strength of their connection and prevents breakage due to excessive weight of the pull rod 22 or the gate 10.

[0058] like Figures 1 to 4 As shown, in some exemplary embodiments of this application, the storage structure 34 includes a fixedly connected support rod 341 and a reinforcing rod 342. The pull rod 22 is provided with a locking platform 223. The support rod 341 extends into the locking platform 223 on the side away from the hydraulic gate opener 21 and forms a limit with the locking platform 223 to support the pull rod 22.

[0059] The locking platform 223 can also cooperate with multiple support rods 341 to form a clamping space. The support rods 341 and the bottom of the protrusions on the locking platform 223 form a limiting position, realizing the storage of the pull rod 22. This configuration structure is more compact and the support rods 341 have better adaptability.

[0060] The support rod 341 of the storage structure 34 is used to directly support the tie rod 22, while the reinforcing rod 342 is used to enhance the stability and load-bearing capacity of the overall structure.

[0061] like Figure 4 As shown in some exemplary embodiments of this application, the two ends of the pull rod 22 are respectively provided with a first pin hole 221 and a second pin hole 222. The first pin hole 221 and / or the second pin hole 222 are detachably connected to the second pin hole 222, the first pin hole 221, the gate 10, or the hydraulic hoist 21 via a pin. This arrangement not only ensures a stable connection between the pull rod 22 and the gate 10 or the hydraulic hoist 21, but also makes the assembly and disassembly of the pull rod 22 simple and quick.

[0062] Understandably, the design of the pin hole and pin shaft ensures a secure connection between the tie rod 22 and other components. Once the pin shaft is inserted into the pin hole, it effectively prevents the tie rod 22 from loosening or falling off during operation. The tight fit between the pin shaft and the pin hole allows the tie rod 22 to remain stable under load, avoiding structural failure due to unstable connection. At the same time, this connection method makes maintenance or replacement of the tie rod 22 more convenient, reducing disassembly and assembly time and improving work efficiency.

[0063] Furthermore, the pin-connection design makes the tie rod 22 easier to assemble and disassemble, reducing maintenance difficulty. When the tie rod 22 needs to be inspected or replaced, it can be quickly disassembled and processed, improving maintenance efficiency.

[0064] In some embodiments, the first pin hole 221 and the second pin hole 222 are respectively formed on two plates extending along the length direction of the tie rod 22, that is, there are two first pin holes 221 and two second pin holes 222, wherein the distance between the two first pin holes 221 is greater than the distance between the two second pin holes 222. This allows the connection between two adjacent tie rods 22 to be achieved by the two second pin holes 222 being located between the two first pin holes 221, the axes of the first pin holes 221 and the second pin holes 222 overlapping, and cooperating with the same pin shaft to achieve connection, thus achieving a stable connection of the tie rods 22.

[0065] like Figure 3 As shown in some exemplary embodiments of this application, the pull rod 22 is provided with a locking platform 223, and the locking structure 31 includes a clamping end 311. After the locking platform 223 passes through the clamping end 311, the clamping end 311 clamps the pull rod 22 and forms a locking connection with the locking platform 223.

[0066] The engagement platform 223 of the pull rod 22 and the clamping end 311 of the locking structure 31 are configured to limit the movement of the pull rod 22. Specifically, the engagement platform 223 is a protrusion extending outward along the circumference of the pull rod 22, which can be an annular or square protrusion. The corresponding clamping end 311 includes two clamping members that can move closer or further apart. The locking process is as follows: the pull rod 22 passes between the two clamping members. After the engagement platform 223 passes through the two clamping members, the two clamping members move closer together, placing them below the protrusion. At this time, the pull rod 22 descends under the action of gravity, causing the protrusion to clamp the two clamping members, thereby limiting the pull rod 22 in the vertical direction. This configuration ensures the stability of the pull rod 22 during the disassembly process.

[0067] The gate mechanism provided in this application embodiment has the following characteristics:

[0068] 1. The structure is simple and easy to operate. It can eliminate the need for maintenance space in the narrow gate slot 40 and allow the maintenance of the pull rod 22 and the gate 10 to be carried out in the maintenance space 50.

[0069] 2. No large lifting equipment is required, reducing maintenance costs and safety risks.

[0070] 3. Through the cooperation of the hydraulic hoist 21, the first lifting device 32 and the second lifting device 33, the quick assembly and disassembly of the pull rod 22 and the gate leaf of the gate 10 are realized.

[0071] 4. A first platform 35 and a second platform 36, as well as a storage structure 34 that can be used to store the pull rod 22, were designed to make the entire disassembly and assembly process more orderly and efficient.

[0072] 5. The use of a fixed first lifting device 32 and a mobile second lifting device 33 increases the flexibility and convenience of operation.

[0073] 6. The maintenance platform is equipped with a locking structure 31 to ensure safety and stability during disassembly and assembly.

[0074] The gate mechanism described in the above embodiments is suitable for use in confined spaces, and is especially suitable for the maintenance of rapid gates inside the intake towers of large hydropower stations. It has the advantages of eliminating the need for large lifting equipment, saving maintenance costs, reducing safety risks, being easy to operate, and having high maintenance efficiency. Its orderly assembly and disassembly reduces confusion and errors during maintenance, and it also offers high safety.

[0075] Secondly, an intake tower is provided. This application provides an intake tower including the gate mechanism described in any of the above embodiments. The beneficial effects of the gate mechanism are described in the above embodiments and will not be repeated here. During the use of the intake tower, frequent maintenance can be performed to ensure that the gate 10's performance is not affected, while maintenance efficiency and operational safety are effectively guaranteed.

[0076] Thirdly, such as Figure 7 As shown, a method for disassembling and assembling a gate mechanism is provided. The gate mechanism is described in any of the above embodiments. The beneficial effects of the gate mechanism are described in the above embodiments and will not be repeated here. The method for disassembling and assembling the gate mechanism includes the following steps:

[0077] S01, the hydraulic hoist 21 lifts the gate 10 and multiple pull rods 22 until the second pull rod 22 on one side of the hydraulic hoist 21 passes through the locking structure 31; this step is to completely remove the first pull rod 22, while the second pull rod 22 is partially removed from the range of the locking structure 31, thereby facilitating the disassembly of the first pull rod 22.

[0078] S02, the second pull rod 22 is locked to the locking structure 31; the second pull rod 22 is temporarily fixed by the locking structure 31 to ensure that when the first pull rod 22 is disassembled, the other pull rods 22 located at the rear end to be disassembled will not move, thus ensuring the safety of the disassembly process.

[0079] S03, the first lifting device 32 and the second lifting device 33 are connected to the first tie rod 22; this step is to ensure that the first tie rod 22 can be lifted and moved smoothly after disassembly.

[0080] Understandably, after the first tie rod 22 is disassembled, the hydraulic hoist 21 that originally supported it no longer provides support. The second tie rod 22 is disconnected and no longer serves a restrictive function. At this time, the first lifting equipment 32 and the second lifting equipment 33 need to provide support to the first tie rod 22.

[0081] S04, disconnect the first tie rod 22 from the hydraulic gate opener 21 and the second tie rod 22; in this way, the first tie rod 22 is separated from the whole structure, preparing for the next step of transfer.

[0082] S05, the first lifting device 32 and the second lifting device 33 drive the first tie rod 22 into the storage structure 34 for temporary storage; the removed tie rod is smoothly transferred into the storage structure 34 by the lifting devices to ensure the stability of the tie rod during temporary storage.

[0083] S06, extend the hydraulic hoist 21 and connect it to the second tie rod 22, and repeat steps S01 to S05 until the hydraulic hoist 21 is connected to the gate 10. In this way, the tie rods are disassembled one by one until the entire disassembly and assembly process is completed.

[0084] The above methods can safely, efficiently, and cost-effectively perform the maintenance and installation of fast gates for large hydropower stations, and are particularly suitable for maintenance environments with limited space.

[0085] Furthermore, in step S01, when the locking platform 223 of the second pull rod 22 passes through the clamping end 311 of the locking structure 31, the clamping end 311 forms a limit for the locking platform 223. At this time, the hydraulic hoist 21 can extend to make the locking platform 223 tightly engage with the clamping end 311, thereby locking the second pull rod 22. At this time, the first pull rod 22 can be disassembled.

[0086] It should be understood that this application is not limited to the detailed structure and arrangement of the components proposed in this application. This application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of this application. It should be understood that the disclosure and definition of this application extends to all alternative combinations of two or more individual features mentioned or apparent in the text and / or drawings. All these different combinations constitute multiple alternative aspects of this application. The embodiments described in this application illustrate the best known mode for implementing this application and will enable those skilled in the art to utilize this application.
