Abstract
Description
Technical Field
[0001] This invention relates to the field of energy dissipation facilities at the inlet of a ship lock, and in particular to a main water conveyance corridor of a lock pier with an energy dissipation structure. Background Technology
[0002] The water outlet of the main water conveyance corridor inside the gate chamber is a structure set inside the gate pier to introduce the water flow of the main water conveyance corridor into the gate chamber. The energy dissipation cover plate is installed above or around the water outlet and is a component that can reduce the energy of the water flow and improve the flow pattern of the water inside the gate chamber.
[0003] However, in the existing structural design of the water conveyance main corridor outlet and energy dissipation cover plate in the gate chamber, there is usually a structural defect of lacking flexible adjustment of energy dissipation methods. The water flow often rushes out directly from the outlet and violently impacts the energy dissipation cover plate. Due to the lack of effective energy dissipation means, the energy of the water flow is difficult to be fully dispersed and consumed, which easily leads to insufficient energy dissipation. Furthermore, it is difficult to adapt to the diverse energy dissipation needs under different flow conditions and velocities. As a result, the energy dissipation cover plate and gate pier are subjected to large impact forces for a long time, increasing their risk of damage. Summary of the Invention

[0011] As a preferred embodiment of the present invention, the impact-resistant component includes several large U-shaped frames disposed on the inner top surface of the energy dissipation cover plate, each of the large U-shaped frames being provided with a small U-shaped frame, a pair of guide sleeves being symmetrically disposed on both sides of the bottom of the large U-shaped frame, and guide posts being disposed at the bottom of the small U-shaped frame corresponding to the positions of the guide sleeves.
[0012] As a preferred embodiment of the present invention, a pair of oil storage cylinders are symmetrically arranged on both sides of the top of each large U-shaped frame, and piston rods are arranged on both sides of the small U-shaped frame corresponding to the positions of the oil storage cylinders. A piston is arranged on the top of the piston rod, and the piston is slidably arranged inside the oil storage cylinder. A spring is arranged between the oil storage cylinder and the piston.
[0013] As a preferred embodiment of the present invention, each of the several small U-shaped frames is provided with a mounting post at its bottom, and the bottom of each of the mounting posts is provided with an impact-resistant plate corresponding to the water outlet.
[0014] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:
[0015] 1. This invention, by setting up an omnidirectional energy dissipation component, consists of a motor, rotating shaft, sun gear, planetary carrier, planetary gears, and ring gear forming a planetary gear system. This system stably transmits the motor power to the drive column, ensuring the smooth rotation of the inner rotating sleeve and swirl blades, generating swirling current, effectively consuming the energy of the water flow, and achieving initial energy dissipation.

[0028] 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 and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.
[0029] like Figures 1-10 As shown, the present invention proposes a gate pier water conveyance main corridor with energy dissipation structure, which includes a gate pier 1, a number of water outlet holes 2 are opened on the top of the gate pier 1, an omnidirectional energy dissipation component 3 is installed in the water outlet holes 2, an energy dissipation cover plate 4 is installed on the gate pier 1 at the position corresponding to the water outlet holes 2, and an impact-resistant component 5 is installed at the bottom of the energy dissipation cover plate 4.
[0030] The omnidirectional energy dissipation assembly 3 includes an outer fixed sleeve 31 mounted on the inner wall of the gate pier 1. The outer fixed sleeve 31 provides an installation base for other components in the omnidirectional energy dissipation assembly 3. An annular guide rail 32 is provided inside the outer fixed sleeve 31, allowing the inner rotating sleeve 33 to rotate on it. The inner rotating sleeve 33 is rotatably mounted on the annular guide rail 32. The rotation of the inner rotating sleeve 33 on the annular guide rail 32 drives the swirl vanes 37 to rotate to generate swirl and dissipate water flow energy. Several support frames 34 are provided at the bottom, which provide support for the drive column 35. The drive column 35 is located in the middle of the support frames 34. The bottom of the drive column 35 is connected to the planetary gear 323 system, which transmits the rotational power to the inner rotating sleeve 33 and the swirl blade 37. Support rods 36 are provided on the outside of the drive column 35 at the positions corresponding to the support frames 34. The support rods 36 provide the mounting base for the swirl blade 37. Each support rod 36 is fitted with a swirl blade 37. When the swirl blade 37 rotates, it generates a swirling flow, which consumes the kinetic energy of the water flow and achieves the purpose of initial energy dissipation.
[0031] A connector 38 is provided on the support frame 34, and a connector 39 is provided at the bottom of the swirl blade 37. A telescopic cylinder 310 is provided between the connector 38 and the connector 39. The telescopic cylinder 310 adjusts the angle of the swirl blade 37 by extending and retracting the telescopic rod to adapt to the energy dissipation requirements under different water flow conditions. A connector 311 is provided between the bottom of the telescopic cylinder 310 and the connector 38. The combination of the connector 38 and the connector 311 allows the telescopic cylinder 310 to rotate at a certain angle. A connector 312 is provided between the top of the telescopic rod of the telescopic cylinder 310 and the connector 39. The combination of the connector 39 and the connector 312 not only transmits power to the swirl blade 37, but also allows the swirl blade 37 to rotate at a certain angle.
[0032] The bottom of the outer fixing sleeve 31 is provided with several support frames 313, which provide support for the mounting box 314. The mounting box 314 is located in the middle of the several support frames 313. The bottom of the drive column 35 passes through the mounting box 314. A sealed bearing 315 is provided on the inner top surface of the mounting box 314 at the position corresponding to the drive column 35. The sealed bearing 315 not only ensures the smooth rotation of the drive column 35, but also effectively prevents water from entering the interior of the mounting box 314 from the gap between the mounting box 314 and the drive column 35. The bottom of the drive column 35 is provided with a mounting groove 316. A gear ring 317 is provided on the inner wall of the bottom of the drive column 35. The gear ring 317 meshes with the planetary gear 323, thereby driving the drive column 35 to rotate.
[0033] The mounting box 314 has a base plate 318 at its bottom, on which a motor 319 is mounted. The motor 319 provides rotational power to the rotating shaft 320. The drive end of the motor 319 is equipped with the rotating shaft 320, which transmits the rotational power of the motor 319 to the sun gear 321. The sun gear 321 is sleeved on the outside of the rotating shaft 320 and meshes with the planetary gear 323, transmitting the rotational power to the planetary gear 323. The base plate 318 is equipped with a row... Planetary carrier 322 is fixed on base plate 318, supports planetary gear 323 and enables it to rotate only on its own axis. Several planetary gears 323 are provided on planetary carrier 322, and all planetary gears 323 mesh with sun gear 321. Gear ring 317 meshes with planetary gears 323. The planetary gears 323 mesh with sun gear 321 and gear ring 317, transmitting rotational power to drive column 35, driving inner rotating sleeve 33 and swirl blade 37 to rotate.
[0034] The impact-resistant component 5 includes several large U-shaped frames 51 set on the inner top surface of the energy dissipation cover plate 4. The large U-shaped frames 51 provide the installation base for other components in the impact-resistant component 5. Each large U-shaped frame 51 is equipped with a small U-shaped frame 52. A pair of guide sleeves 53 are symmetrically arranged on both sides of the bottom of the large U-shaped frame 51. Guide posts 54 are arranged at the bottom of the small U-shaped frame 52 corresponding to the positions of the guide sleeves 53. The combination of guide sleeves 53 and guide posts 54 guides the up and down movement of the small U-shaped frame 52 to ensure its stable operation.
[0035] Each large U-shaped frame 51 has a pair of oil reservoirs 55 symmetrically arranged on both sides of its top. The oil reservoirs 55 store hydraulic oil and work with piston 57 to generate damping force, consuming the impact force of the water flow. Piston rods 56 are arranged on both sides of the small U-shaped frame 52 corresponding to the positions of the oil reservoirs 55. Piston 57 is arranged on the top of the piston rods 56 and slides inside the oil reservoirs 55. The piston rods 56 and piston 57 move inside the oil reservoirs 55 under the push of the small U-shaped frame 52, generating damping force through the flow of hydraulic oil. A spring 58 is arranged between the oil reservoirs 55 and piston 57. The spring 58 absorbs the impact force of the water flow and contracts, assisting the damping force in consuming the impact force.
[0036] Each of the small U-shaped frames 52 has a mounting post 510 at its bottom. The mounting post 510 connects the small U-shaped frame 52 and the impact plate 59, transmitting the impact force of the water flow to the small U-shaped frame 52 and dissipating it. The bottom of each mounting post 510 is provided with an impact plate 59 corresponding to the water outlet 2. The impact plate 59 is in direct contact with the water flow and bears the impact force of the water flow.
[0037] Working principle: When water flows into the gate chamber, the omnidirectional energy dissipation component 3 starts to work. The motor 319 drives the rotating shaft 320 to start rotating. When the rotating shaft 320 rotates, it drives the sun gear 321 connected to it to rotate synchronously. Since the sun gear 321 meshes with the planetary gear 323, the power is transmitted to the planetary gear 323. Since the planet carrier 322 is fixed on the base plate 318, the planetary gear 323 can only rotate on its own axis. While the planetary gear 323 rotates, it drives the drive column 35 to rotate due to its meshing relationship with the bottom gear ring 317 of the drive column 35. When the drive column 35 rotates, it drives the inner rotating sleeve 33 to rotate on the annular guide rail 32, which in turn causes the swirl vane 37 to rotate. When the swirl vane 37 rotates, it generates a swirling flow, which can effectively consume the energy of the water flow and achieve the purpose of initial energy dissipation. During this process, the operator can adjust the angle of the swirl vane 37 by controlling the extension and retraction of the telescopic rod of the telescopic cylinder 310 according to actual needs, so as to further optimize the energy dissipation effect.
[0038] After the water flow undergoes initial energy dissipation through the omnidirectional energy dissipation component 3, it continues to flow forward and reaches the energy dissipation cover plate 4. At this point, the water flow generates an impact force on the energy dissipation cover plate 4. The water flow first contacts the impact-resistant plate 59. After being subjected to force, the impact-resistant plate 59 moves upward and pushes the small U-shaped frame 52 upward. During this process, the spring 58 absorbs the impact and contracts. At the same time, the small U-shaped frame 52 pushes the piston rod 56 and piston 57 to move inside the oil reservoir 55. Piston 57 divides the space inside the oil reservoir 55 into two chambers. The hydraulic oil in the oil reservoir 55 will repeatedly flow from one chamber to another through different small holes on piston 57. The friction between the hole wall and the hydraulic oil and the internal friction between the hydraulic oil molecules will hinder the flow of hydraulic oil, thereby generating a damping force, further consuming the impact force of the water flow, achieving the purpose of further energy dissipation, and effectively protecting the energy dissipation cover plate 4 and the gate pier 1 from damage. The energy-dissipated water flow enters the gate chamber through the gap between the energy dissipation cover plate 4 and the outlet hole 2, ensuring that the water level change in the gate chamber is uniform.
[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
