Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a water retaining gate used in water conservancy projects. Background Art

[0002] With the continuous expansion of the scale of water conservancy projects and the continuous improvement of the dispatching and management level, the water gate, as a key hydraulic structure, plays an increasingly important role in various water conservancy facilities. It is not only used to adjust the water level difference between upstream and downstream and control the flow of water in rivers or channels, but also to perform emergency functions such as flood discharge and drainage when floods come. At the same time, in scenarios such as reservoir water storage, hydropower station peak regulation operation, and irrigation water source allocation, the water gate is also an important tool for achieving scientific dispatch, ensuring project safety, and improving resource utilization efficiency.

[0003] In the prior art, water conservancy gate devices have some defects that cannot fully meet the needs of modern water conservancy projects. First, the gate surface is prone to accumulation of sediment, impurities, etc. These sediments often lead to increased friction between the guide rail and the water retaining plate, which may eventually cause the gate to get stuck or operate poorly. However, the existing cleaning methods often rely on regular manual cleaning or simple scraping by mechanical devices. The cleaning effect is unstable and cannot be flexibly adjusted according to the degree of sediment adhesion. It is often impossible to remove the attachments in a timely and effective manner, resulting in equipment failures and increased maintenance frequency.

[0004] Secondly, in the existing technology, most gate systems do not have an effective buffer structure. The water retaining plate directly hits the bottom at the end of the downward movement, causing a large impact force, which easily leads to equipment structural damage, seal failure and vibration problems. This not only aggravates structural wear, but also increases the maintenance cost of the equipment and shortens its service life.

[0005] Finally, existing manual control systems usually rely on the operator's experience and judgment, lack the necessary safety interlock mechanism, cannot provide reliable safety protection, and are prone to unexpected operating errors. Especially when personnel are unfamiliar or negligent, the safety of the gate device cannot be fully guaranteed. Summary of the invention

[0022] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please see attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides a water-blocking gate for a water conservancy project, including a gate frame 1 arranged at a water channel or a water storage port, which is used to support and limit the installation position of the entire gate device. A mud inlet groove 12 is provided at the bottom of the gate frame 1, and the mud inlet groove 12 is used to collect the silt particles brought in by the water flow or peeled off from the surface of the water baffle 2 during the lifting process of the water baffle 2. A plurality of mud discharge holes 11 are evenly opened inside the mud inlet groove 12, which facilitates the discharge of the accumulated mud from the mud discharge holes 11 by gravity or scouring to avoid siltation and blockage. The water baffle 2 is slidably connected inside the gate frame 1 to achieve the blocking or release of the water flow. In order to ensure the stability and guiding accuracy of the up and down movement of the water baffle 2, two limiting side plates 21 are fixedly connected on both sides thereof, and the limiting side plates 21 are inserted and slidably matched in the guide groove 13 symmetrically arranged on the inner side of the gate frame 1, which effectively prevents deviation and jamming. A sealing sleeve layer is provided between the limiting side plate 21 and the guide groove 13 to prevent the water flow from directly passing through the water baffle 2. A threaded rod 3 is vertically fixed at the top center of the water baffle 2, and the threaded rod 3 penetrates into the protection box 4 at the top of the gate frame 1. The protection box 4 is used to protect the manual drive assembly 5 and the threaded transmission mechanism from the external environment, thereby improving the reliability and service life of the structure. The manual drive assembly 5 is located at the top of the frame, and the lifting and lowering adjustment of the water baffle 2 can be manually realized. In order to prevent the equipment from being accidentally started when the water pressure is large or in a non-operating state, an interlocking mechanism 8 is arranged on the outside of the manual drive assembly 5, and the driving structure is locked by a mechanical latch to ensure safe operation. In order to prevent mud and sand from adhering to the front side of the water baffle 2 and affecting the sealing and lifting, a cleaning mechanism 7 is arranged on the front side of the water baffle 2, and the mechanism is combined with the adjustable angle structure to realize more efficient cleaning of the front side of the water baffle 2. In addition, two buffer assemblies 9 are arranged at the bottom of the gate frame 1, and their positions correspond to the downward terminal position of the water baffle 2, which are used to provide elastic buffering when the water baffle 2 falls rapidly, absorb impact force, protect the frame structure, and improve the safety and durability of the overall operation.

[0024] Please see attached Figure 7 -Attached Figure 8The buffer assembly 9 is used to provide effective energy absorption and buffer protection when the water retaining plate 2 falls to the bottom. Its structural design is reasonable, the response performance is excellent, and it can significantly reduce the structural impact and vibration. The buffer assembly 9 includes a force-bearing plate 901 arranged at the top thereof for direct pressure bearing. The force-bearing plate 901 bears the vertical impact force generated when the water retaining plate 2 falls, and evenly transmits the force to the lower buffer structure. Two damping rods 908 are respectively arranged on both sides of the bottom of the force-bearing plate 901 to provide preliminary displacement damping and force guiding functions. The bottoms of the two damping rods 908 are fixedly mounted on two bases 907 respectively arranged inside the gate frame 1, which play a role of stable support and structural limitation. A sliding rod 902 is horizontally arranged between the two bases 907, and a strong spring 903 is tightly sleeved on the outer side of the middle part of the sliding rod 902. The strong spring 903 has the characteristics of high-strength rebound and large deformation, and can absorb a large amount of impact energy in a short time. In order to achieve synchronous transmission and stable guidance of the spring force, two sliding sleeves 904 are symmetrically arranged at both ends of the slide bar 902. Both sliding sleeves 904 can slide axially on the outside of the slide bar 902 and are fixedly connected to the two ends of the strong spring 903, so as to deform cooperatively during the buffering process. In addition, two rotating seats 906 are symmetrically arranged at the bottom of the force-bearing plate 901. The two rotating seats 906 are respectively arranged on one side close to the sliding sleeve 904 and are connected by the rotating rod 905 to transmit a certain rotational force component and introduce a rotational torque during the impact absorption process, thereby further improving the energy mitigation efficiency and stability. This structure realizes the full-range energy absorption buffering of the falling impact of the water retaining plate 2 through the combined action of mechanical elasticity and displacement sliding, which effectively prolongs its service life while improving the safety performance of the gate device.

[0025] Please see attached Figure 2The manual drive assembly 5 includes a hand wheel 501 disposed at the top of the gate, which is driven by the operator to rotate. A connecting rod 502 is provided inside the center of the hand wheel 501. The connecting rod 502 is coaxially installed with the axis of the hand wheel 501 and rotates synchronously with it. One end of the connecting rod 502 is fixedly connected with a bevel gear 1 503, which is used to change the direction of rotation and transmit it to the vertical direction. The bevel gear 1 503 is meshed with the bevel gear 2 504 disposed on the outside of the threaded rod 3, thereby realizing the conversion from horizontal rotation to vertical spiral transmission. The bottom of the bevel gear 2 504 is connected with a sleeve 505, which is externally rotatably connected to the top area of ​​the gate frame 1, and can achieve smooth rotation while maintaining axial stability through a bearing assembly or a sliding fit structure. Through the accurate meshing transmission between the bevel gear 1 503 and the bevel gear 2 504, each rotation of the hand wheel 501 can accurately drive the threaded rod 3 to rise, thereby controlling the lifting displacement of the water retaining plate 2. In order to enhance the structural stability and load-bearing capacity of the entire transmission system, a load-bearing plate 6 is provided on one side of the top of the gate frame 1. The load-bearing plate 6 is made of high-strength steel plate or aluminum alloy plate and is fixedly mounted on the frame structure to support the weight of the connecting rod 502 and its rotating accessories and withstand the torque and reaction force from the operation process. The outer side of the connecting rod 502 is connected to the inner wall of the load-bearing plate 6 in an axial rotation manner, and low friction and high reliability operation during the rotation process are ensured by a shaft pin or a ball bearing.

[0026] Please see attached Figure 2 To Attachment Figure 4The cleaning mechanism 7 as a whole is composed of a cleaning component 71, an adjustment component 72 and a limit bend plate 73. It has good adaptive cleaning ability and adjustable performance, can effectively prevent sediment from accumulating on the surface of the water retaining plate 2, and improve the smoothness of the guide operation and the sealing effect. Among them, the cleaning component 71 includes a scraper 711 arranged along the front side of the water retaining plate 2. One side of the scraper 711 is connected to the front surface of the water retaining plate 2 by sliding, and can be close to its surface to peel off sediment during the lifting and lowering of the water retaining plate 2. A rotating shaft 712 that runs through the width of the scraper 711 is provided inside the scraper 711. The rotating shaft 712 plays a role in driving the angle change of the scraper 711. Its two ends are respectively installed in the rotating support structure inside the gate frame 1, and a worm gear 713 for transmission is provided on the outside of one end. In order to realize manual adjustment and control of the angle of the scraper 711, a worm 714 is vertically installed inside the gate frame 1. The worm 714 meshes with the worm wheel 713 at the lower end to form a transmission structure, which can realize efficient and stable angle adjustment operation under limited space conditions. A rotating wheel 715 is provided on the top of the worm 714, and the rotating wheel 715 is exposed above the gate frame 1, which is convenient for the operator to manually rotate and adjust, so that the scraper 711 can adjust the sediment adhesion at different angles to improve the cleaning coverage and efficiency. The adjustment component 72 includes two fixed blocks 721 installed at both ends of the rotating shaft 712. The fixed blocks 721 serve as a connecting carrier between the scraper 711 and the gate frame 1. An adjustment spring 722 is provided on the rear side of each of the fixed blocks 721, which can provide a controllable pressing force when the scraper 711 is attached to the surface of the water retaining plate 2, ensuring the cleaning effect while avoiding excessive friction on the surface of the water retaining plate 2. This structure allows the scraper 711 to rebound appropriately when encountering obstacles, thereby enhancing its service life. In addition, in order to prevent the worm 714 from positional displacement or abnormal rotation during operation, a limit bending plate 73 is sleeved on its exterior, and guide structures are provided at both ends of the bottom of the limit bending plate 73, which are respectively slidably connected to the preset slide grooves at the top of the gate frame 1, to ensure that the worm 714 always maintains a stable vertical guide during the entire cleaning operation, and to avoid abnormal operation of the scraper 711 caused by operational deviation. The cleaning mechanism 7 has a compact overall structure and reliable transmission, and can flexibly adjust the angle and fit of the scraper 711 according to different use environments, significantly improving the safety of gate operation and the convenience of maintenance.

[0027] Please see attached Figure 5 -Attached Figure 6The interlocking mechanism 8 is used to forcibly mechanically lock the manual drive assembly 5 in the non-operating state, so as to effectively prevent the accidental or erroneous rotation of the hand wheel 501, which causes the water baffle 2 to rise and fall unexpectedly, and ensure the safety of personnel and structures during the operation of the water conservancy facility. The interlocking mechanism 8 mainly includes a fixed assembly 81, a locking bent rod 82 and a limit assembly 83, which has a compact structure, strong interlocking and sensitive response. The fixed assembly 81 includes a fixed ring 811 and a sliding ring 812, wherein the fixed ring 811 is fixedly installed at one end outside the connecting rod 502 to form a rigid support reference, and the sliding ring 812 is slidably connected to the outside of the other end of the connecting rod 502 and can move axially along the connecting rod 502. In order to realize the automatic reset function, a reset spring 813 is provided between the fixed ring 811 and the sliding ring 812. The reset spring 813 is tightly sleeved on the outside of the connecting rod 502 and has good elastic recovery performance. After the lock is released, the sliding ring 812 can be quickly restored to the initial position. The limit assembly 83 is arranged between the sliding ring 812 and the connecting rod 502, and is used to guide the sliding direction and control the sliding range. The limit assembly 83 further includes a plurality of T-shaped bent plates 831, which are evenly distributed and fixedly connected to the inner wall of the sliding ring 812 in a mutually opposite manner, and the shape matches the limit inner groove 832 opened on the connecting rod 502, and can slide stably in the groove, thereby ensuring the posture stability and limit accuracy of the sliding ring 812 during the axial movement. A plurality of fixing rods 814 are arranged around the side of the sliding ring 812 away from the fixing ring 811, which are used to be inserted into the plurality of fixing holes 61 set on the load-bearing plate 6 to achieve physical locking with the overall structure of the device. In order to further strengthen the locking structure, the tops of the fixed ring 811 and the sliding ring 812 are respectively provided with a locking hole 1 8111 and a locking hole 2 8121. When the sliding ring 812 is in the locked position, the two ends of the bottom of the limit assembly 83 can be accurately inserted into the above-mentioned locking hole, forming a complete triple locking path, namely, the limit groove guide, the fixed rod 814 insertion and the locking hole positioning, which effectively prevents the rotation of the drive structure caused by vibration, accidental touch or external force interference, and ensures the uniqueness and safety of the system operation. The locking bent rod 82 can be used as an additional human intervention device. Before operation, the locking state can be released by pulling back the sliding ring 812 and inserting the locking bent rod 82 into the locking hole. At this time, the hand wheel 501 can be rotated, further improving the operational safety level of the device.

[0028] Working principle: The operator first rotates the hand wheel 501, and the connecting rod 502 inside the hand wheel 501 drives the bevel gear 1 503 fixedly connected to one end thereof to rotate, and the bevel gear 1 503 meshes with the bevel gear 2 504 sleeved on the outside of the threaded rod 3, and the horizontal rotational motion is converted into vertical rotation through the bevel gear transmission structure, thereby driving the threaded rod 3 to move up and down, and then driving the water retaining plate 2 to move up and down along the guide groove 13 inside the gate frame 1. During the lifting and lowering process of the water retaining plate 2, the scraper 711 slidingly connected on the front side is driven to rotate by the rotating shaft 712 to achieve cleaning, and the worm wheel 713 at one end of the rotating shaft 712 meshes with the worm 714, and the operator can manually adjust the rotation of the worm 714 through the rotating wheel 715, thereby controlling the angle of the scraper 711. When the water retaining plate 2 drops to the bottom, its lower surface first contacts the force-bearing plate 901, and under the action of pressure, the damping rod 908 and the sliding rod 902 structure below the force-bearing plate 901 are compressed, and the strong spring 903 on the sliding rod 902 is compressed and deformed to achieve energy buffering. At the same time, the sliding sleeve 904 slides outside the sliding rod 902, driving the rotating rod 905 in the rotating seat 906 to move to release part of the rotational stress. In the non-operating state, the fixed ring 811 and the sliding ring 812 located outside the connecting rod 502 maintain the initial spacing through the reset spring 813, and the multiple fixed rods 814 on the sliding ring 812 are inserted into the fixed holes 61 on the load-bearing plate 6 to achieve interlocking and prevent malfunction of the drive. The T-shaped bent plate 831 slides in the limiting inner groove 832, and at the same time, the bottom of the locking bent rod 82 is inserted into the internal locking hole 1 8111 and the locking hole 2 8121 of the fixed ring 811 and the sliding ring 812, and the hand wheel 501 can be rotated at this time. After the operation is completed, the reset structure can automatically return the interlocking mechanism 8 to the locked state, and the equipment cycle working process ends.
