Description

Technical Field

[0001] The invention relates to the technical field of gates for water conservancy projects, and in particular to a gate structure for water conservancy projects. Background Art

[0002] The gate structure of a water conservancy project is a vital component of a water conservancy project. It is mainly used to close and open the discharge channel to regulate flow, control water level, discharge floods, remove silt or floating objects, etc. The water flow often carries various impurities, such as silt, stones, branches, plastic bags, aquatic plants, etc. These impurities will not only pollute the downstream water body, but also increase the wear of the gate if these impurities directly impact the gate, shorten its service life, and may also cause blockage or damage to the gate.

[0003] A Chinese patent with announcement number CN114808872B discloses a flood control gate for a water conservancy project, wherein a concrete layer is poured on the riverbed where the gate is located, gate piers are arranged on both sides of the gate, a gate beam is arranged on the top of the gate pier, a filter plate is arranged on the concrete layer, gate piers are arranged on both sides of the filter plate, a gate beam is arranged on the top of the gate pier, scrapers are slidably installed on the relative inner sides of the two gate beams, the scrapers and the filter plates are fitted with each other, a lead screw is rotatably installed on the concrete layer, the scraper is threadedly connected to the lead screw, a motor is installed on the top of the gate beam, and the output shaft of the motor is coaxially connected to the lead screw. The filter plate in the above technical solution filters impurities in the water flow. When the operator needs to clean the foreign matter attached to the filter plate, the motor 1 is started, and the output shaft of the motor 1 drives the screw 1 to rotate, and the screw 1 drives the scraper to move downward along the surface of the filter plate, so that foreign matter such as garbage and aquatic plants attached to the filter plate can be removed from the filter plate, thereby improving the filtering capacity of the filter plate.

[0004] The filter plate in the above technical solution is vertically arranged between the two gate piers. When the gate is in the closed stage, the water level upstream of the gate will be higher than that downstream. When the gate is opened, the water level will gradually drop. As the water level drops, the part above the filter plate will not be able to be used, so that the utilization of the filter plate is limited. Moreover, the part above the filter plate will be exposed above the water surface, which will cause impurities to dry on the filter plate for a long time, increasing the difficulty of cleaning.

[0005] Therefore, the art needs a water conservancy engineering gate structure to solve the above problems. Summary of the invention

[0006] The present invention provides a water conservancy project gate structure, aiming to solve the problem in the related art that the filter plate at the gate cannot be adjusted according to the water level, resulting in limited utilization of the filter plate and impurities being easily dried on the filter plate and difficult to clean.

[0007] A water conservancy project gate structure of the present invention comprises a U-shaped mounting seat, a gate assembly and a filter plate arranged on the mounting seat, a mounting beam is arranged on the top of the mounting seat, the mounting beam is vertically slidably connected to the mounting plate, the top of the filter plate is rotatably connected to the mounting plate, the bottom of the filter plate is horizontally slidably connected to the side wall of the mounting seat, the filter plate is in a state of being inclined from the top end to the bottom end toward the downstream direction, and the mounting plate is fixedly connected to the buoyancy assembly;

[0008] When the water level rises, the buoyancy assembly drives the mounting plate to move upward, and the mounting plate drives the top of the filter plate to move upward to increase the angle between the filter plate and the horizontal direction. When the water level drops, the buoyancy assembly drives the mounting plate to move downward, and the mounting plate drives the top of the filter plate to move downward to reduce the angle between the filter plate and the horizontal direction.

[0009] The present invention provides a buoyancy component so that the buoyancy component drives the filter plate to move following the change of the water level. Compared with a fixed filter plate, the filter plate of the present invention has a larger area that can play a filtering role during use, thereby improving the utilization rate of the filter plate. Moreover, most of the filter plate is immersed below the liquid level, thereby avoiding the impurities filtered out of the filter plate from being exposed to the air for a long time and being difficult to clean.

[0010] Preferably, the buoyancy assembly includes a buoyancy plate and air floats fixedly connected to both sides of the buoyancy plate, and the buoyancy plate is fixedly connected to the mounting plate via a connecting plate.

[0011] Preferably, the bottom of the mounting seat is slidably connected with a movable plate in the horizontal direction, the movable plate is located downstream of the filter plate, and a driving component 1 for driving the movable plate to move in the horizontal direction is provided on the mounting beam. The gate assembly includes a gate and a driving component 2 for driving the gate to open and close. When the driving component 2 drives the gate to open, the driving component 1 drives the movable plate to move in the downstream direction to below the gate.

[0012] During the movement of the filter plate, the silt may be pushed under the gate, affecting the normal closing of the gate. When there is a lot of silt, it may also affect the normal movement of the filter plate. The present invention drives the movable plate to the bottom of the gate through a driving component 1, which can push the silt deposited between the gate and the filter plate to the downstream of the gate, thereby preventing the silt from affecting the movement of the filter plate and the normal closing of the gate.

[0013] Preferably, driving assembly 1 includes rack 1, gear and rack 2, rack 1 is vertically fixedly connected to the gate, the gear is rotatably connected to the mounting beam, the movable plate is fixedly connected to the mounting rod extending above the mounting seat, rack 2 is horizontally fixedly connected to the mounting rod, rack 1 and rack 2 are respectively meshed with the gear, when the gate is opened, rack 1 drives rack 2 and the mounting rod to move in the downstream direction through the gear, and the mounting rod drives the movable plate to move in the downstream direction.

[0014] The movable plate is driven to move by the opening and closing of the gate, thus avoiding the addition of a new driving source and reducing the cost.

[0015] Preferably, both ends of the bottom of the filter plate are rotatably connected with sliders, which are slidably connected to the side walls of the mounting seat in the horizontal direction. A baffle is fixedly connected to the downstream side of the slider, and a first slope is provided on the upstream side of the movable plate and a second slope is provided on the downstream side. When the gate is closed, the movable plate abuts against the baffle.

[0016] The filter plate is slidably connected to the mounting seat through a slider, which improves the stability of the filter plate during movement. By setting the inclined plane 1 and the baffle, when the slider drives the filter plate to move and reset in the upstream direction, the silt deposited between the movable plate and the filter plate will be squeezed to the top of the movable plate under the action of the inclined plane 1 and the baffle, thereby avoiding too much silt from being deposited between the filter plate and the movable plate, which would affect the movement of the filter plate as the water level drops.

[0017] Preferably, the bottom of the mounting seat is provided with a third slope on the side facing upstream and a fourth slope on the side facing downstream, and when the movable plate moves to below the gate, the second slope passes over the fourth slope.

[0018] By setting the inclined plane four, when the movable plate pushes the silt to the side of the gate facing downstream, the silt can flow along the inclined plane four with the water flow, thereby preventing a large amount of silt from accumulating downstream of the mounting seat.

[0019] Preferably, a scraper is provided on the side of the gate facing downstream, and the scraper is elastically connected to the mounting beam through an elastic telescopic rod. A push plate is rotatably connected to the gate, and a torsion spring is provided at the rotating connection. During the opening of the gate, the push plate pushes the scraper to move upward, and when the movable plate moves to the bottom of the gate, the push plate is separated from the scraper, and the elastic telescopic rod drives the scraper downward to press against the top of the movable plate.

[0020] By arranging the scraper, when the movable plate moves in the upstream direction, the scraper can scrape off the silt on the movable plate to avoid a lot of silt being accumulated on the movable plate.

[0021] Preferably, the mounting beam is fixedly connected with an elastic push rod arranged in the vertical direction, and the bottom end of the elastic push rod can contact the buoyancy assembly.

[0022] Preferably, a dirt collecting plate is provided on the upstream side of the filter plate, and both sides of the dirt collecting plate are in contact with the side walls of the mounting seat. A motor is fixedly connected to the mounting beam, and a screw is fixedly connected to the output end of the motor. The dirt collecting plate is threadedly connected to the screw. The motor drives the screw to rotate, and the screw drives the dirt collecting plate to move, and the dirt collecting plate cleans the upstream side of the filter plate.

[0023] By setting up a dirt collecting plate, after the gate is closed, the impurities filtered by the filter plate can fall and be collected in the dirt collecting plate, and the impurities on the filter plate can be scraped and cleaned by driving the lead screw to rotate by the motor.

[0024] Preferably, the gate is slidably connected to the two side walls of the mounting seat along the vertical direction, and the driving component 2 includes a motor 2 and a screw 2. The motor 2 is fixedly connected to the mounting beam, the screw 2 is fixedly connected to the output end of the motor 2, the gate is threadedly connected to the screw 2, the motor 2 drives the screw 2 to rotate, and the screw 2 drives the gate to move vertically.

[0025] The beneficial effects of the present invention are as follows: by arranging a buoyancy component, when the gate component is opened to release water, the buoyancy component can drive the filter plate to move following the change of the water level. Compared with a fixed filter plate, the filter plate of the present invention has a larger area that can play a filtering role during use, thereby improving the utilization rate of the filter plate. Moreover, most of the filter plate is immersed below the liquid level, thereby avoiding the impurities filtered out of the filter plate from being exposed to the air for a long time and being difficult to clean.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 6 As shown, a water conservancy project gate structure of the present invention includes a U-shaped mounting seat 1, a gate assembly and a filter plate 2 arranged on the mounting seat 1. The side of the mounting seat 1 facing the upstream direction is defined as the right side, and the side facing the downstream direction is defined as the left side. Two mounting beams 3 are fixedly connected to the top of the mounting seat 1, and the mounting beam 3 located on the right side is vertically slidably connected to the mounting plate 4, and the front and rear side walls of the mounting seat 1 are respectively provided with slide grooves 11 extending in the left and right directions. The top of the filter plate 2 is rotatably connected to the mounting plate 4, and the front and rear ends of the bottom of the filter plate 2 are respectively rotatably connected to sliders 21, and the sliders 21 slide in cooperation with the corresponding slide grooves 11 in the left and right directions. The filter plate 2 is located upstream of the gate assembly, and the filter plate 2 is in a state of being tilted from the top to the bottom toward the downstream direction.

[0036] The mounting plate 4 is fixedly connected with a buoyancy assembly, which includes a buoyancy plate 5 and air floats 51 fixedly connected to both sides of the buoyancy plate 5 . The buoyancy plate 5 is fixedly connected to the mounting plate 4 via a connecting plate 52 .

[0037] When the water level rises, the buoyancy assembly drives the mounting plate 4 to move upward, the mounting plate 4 drives the top of the filter plate 2 to move upward, and the slider 21 at the bottom of the filter plate 2 moves to the right along the chute 11 to increase the angle between the filter plate 2 and the horizontal direction, ensuring that the filter plate 2 can filter the passing water. When the water level drops, the buoyancy assembly drives the mounting plate 4 to move downward, the mounting plate 4 drives the top of the filter plate 2 to move downward, and the slider 21 at the bottom of the filter plate 2 moves to the left along the chute 11 to reduce the angle between the filter plate 2 and the horizontal direction, so that the filter plate 2 follows the drop in the water level, so that as much area of ​​the filter plate 2 as possible can play a filtering role, improve the utilization of the filter plate 2, and at the same time avoid the impurities filtered from the filter plate 2 being exposed to the air for a long time and difficult to clean.

[0038] like Figure 2 As shown, the gate assembly includes a gate 6 and a driving assembly 2 for driving the gate 6 to open and close. The gate 6 slides with the mounting seat 1 vertically. The driving assembly 2 includes a motor 2 61 and a lead screw 2 62. The motor 2 61 is fixedly connected to the mounting beam 3 located on the left side, and the lead screw 2 62 is fixedly connected to the output end of the motor 2 61. The gate 6 is threadedly connected to the lead screw 2 62. The motor 2 61 drives the lead screw 2 62 to rotate, and the lead screw 2 62 drives the gate 6 to move vertically. When the gate 6 moves upward, the water flow channel is opened, and when the gate 6 moves downward, the water flow channel is closed.

[0039] like Figure 2 and Figure 6 As shown, after long-term use, more silt may be deposited on the left side of the bottom of the filter plate 2. Since the filter plate 2 moves with the change of water level, the silt may be pushed to the bottom of the gate 6 during the movement of the filter plate 2, affecting the normal closing of the gate 6. Moreover, when there is more silt, it may also affect the normal movement of the filter plate 2. Therefore, in this embodiment, the bottom of the mounting seat 1 is connected with a movable plate 7 in a sliding manner in the left-right direction. The movable plate 7 is located downstream of the filter plate 2, that is, on the left side. The mounting beam 3 located on the left side is provided with a driving component 1 for driving the movable plate 7 to move in the left-right direction. When the driving component 2 drives the gate 6 to open, the driving component 1 drives the movable plate 7 to move in the downstream direction to the bottom of the gate 6, and pushes the silt deposited between the gate 6 and the filter plate 2 to the left side of the gate 6, so as to prevent the silt from affecting the movement of the filter plate 2 and the normal closing of the gate 6.

[0040] like Figure 2 and Figure 3 As shown, the driving assembly 1 includes a rack 1 63, a gear 31 and a rack 2 72, the rack 1 63 is fixedly connected to the gate 6 in a vertical direction, the gear 31 is rotatably connected to the mounting beam 3 on the left side, the movable plate 7 is fixedly connected to the mounting rod 71 extending above the mounting seat 1, the rack 2 72 is fixedly connected to the mounting rod 71 in a horizontal direction, and the rack 1 63 and the rack 2 72 are respectively meshed with the gear 31. In the process of opening the gate 6, the rack 1 63 drives the rack 2 72 and the mounting rod 71 to move in the downstream direction through the gear 31, and the mounting rod 71 drives the movable plate 7 to move in the downstream direction.

[0041] like Figure 2 and Figure 6As shown, the side of the slider 21 facing downstream is fixedly connected with the baffle 22, and the side of the movable plate 7 facing upstream is provided with an inclined surface 1 73, and the side of the movable plate 7 facing downstream is provided with an inclined surface 2 74. In the process of closing the gate 6 downward, the rack 1 63 drives the rack 2 72 and the mounting rod 71 to move in the upstream direction through the gear 31, and the mounting rod 71 drives the movable plate 7 to move in the upstream direction. The movable plate 7 abuts against the baffle 22 and pushes the baffle 22 and the slider 21 to move in the upstream direction. The slider 21 drives the top of the filter plate 2 to move upward and reset. At the same time, during the water discharge process, the silt deposited between the movable plate 7 and the filter plate 2 is squeezed to the top of the movable plate 7 under the action of the inclined surface 1 73 and the baffle 22, so as to avoid too much silt deposited on the left side of the bottom of the filter plate 2, which affects the movement of the filter plate 2 following the drop in the water level.

[0042] like Figure 4 and Figure 6 As shown, the bottom of the mounting seat 1 is provided with a slope 3 12 on the side facing upstream and a slope 4 13 on the side facing downstream. When the movable plate 7 moves to the bottom of the gate 6, the slope 2 74 passes over the slope 4 13. The gate 6 is provided with a scraper 8 on the side facing downstream, i.e., on the left side. The scraper 8 is connected to a support frame 81. The front and rear sides of the support frame 81 are in contact with the front and rear side walls of the mounting seat 1. The top of the support frame 81 is elastically connected to the mounting beam 3 on the left side through an elastic telescopic rod 82. The left side of the gate 6 is rotatably connected to a push plate 64, and a torsion spring (not shown in the figure) is provided at the rotation connection. The push plate 64 is in a horizontal state when not subjected to external force.

[0043] During the process of opening the gate 6 upward, the pushing plate 64 pushes the top of the support frame 81 to drive the scraper 8 to move upward. When the movable plate 7 moves to the bottom of the gate 6, the pushing plate 64 is separated from the top of the support frame 81, and the elastic telescopic rod 82 drives the support frame 81 to drive the scraper 8 downward to lean against the top of the movable plate 7. When the gate 6 is closed and drives the movable plate 7 to move to the right, the scraper 8 scrapes the silt on the top of the movable plate 7, and the silt falls along the inclined surface 2 74 of the movable plate 7 onto the inclined surface 4 13 of the mounting seat 1, and flows along the inclined surface 4 13 with the water flow, so as to clean the silt on the movable plate 7. After the movable plate 7 is separated from the scraper 8, the scraper 8 continues to move downward until it abuts against the bottom of the mounting seat 1 under the elastic force of the elastic telescopic rod 82. When the gate 6 continues to move downward until the push plate 64 contacts the top of the support frame 81, the push plate 64 rotates upward under the stop of the support frame 81 until the push plate 64 follows the gate 6 to move away from the support frame 81. The push plate 64 returns to a horizontal state under the action of the torsion spring and is located below the top of the support frame 81, thereby realizing the resetting of the push plate 64.

[0044] The mounting beam 3 on the right side is fixedly connected with an elastic push rod 32 arranged vertically, and the bottom end of the elastic push rod 32 can contact the buoyancy assembly. When the slider 21 at the bottom of the filter plate 2 is located at the right end of the chute 11, the angle between the filter plate 2 and the horizontal direction is the largest, and the bottom end of the elastic push rod 32 is against the buoyancy assembly. The elastic push rod 32 is in a compressed state. When the gate 6 is opened and the movable plate 7 moves to the left and loses the top push on the filter plate 2, the filter plate 2 has a tendency to move downward under the action of the elastic push rod 32. As the drainage time increases, after the water level drops, the buoyancy assembly can drive the filter plate 2 to move downward smoothly under the action of the elastic push rod 32 to adapt to the current water level.

[0045] like Figure 2 As shown, a dirt collecting plate 9 is provided on the side of the filter plate 2 facing upstream, that is, on the right side, and both sides of the dirt collecting plate 9 fit with the side walls of the mounting seat 1. A motor 91 is fixedly connected to the mounting beam 3, and a lead screw 92 is fixedly connected to the output end of the motor 91, and the dirt collecting plate 9 is threadedly connected with the lead screw 92. When the dirt collecting plate 9 is located at the bottom of the mounting seat 1, the bottom of the dirt collecting plate 9 fits with the inclined surface 3 12 of the mounting seat 1, and the side of the dirt collecting plate 9 close to the filter plate 2 can fit with the filter plate 2. When the movable plate 7 pushes the filter plate 2 to reset until the slider 21 of the filter plate 2 abuts against the right end of the chute 11, the motor 91 drives the lead screw 92 to rotate, and the lead screw 92 drives the dirt collecting plate 9 to move upward, and the dirt collecting plate 9 cleans the side of the filter plate 2 facing upstream. After the dirt collecting plate 9 moves above the water surface, the impurities scraped and collected in the dirt collecting plate 9 can be cleaned manually.
