Description

Technical Field

[0001] The invention relates to the technical field of reservoir drainage gates, and in particular to a reservoir drainage gate based on water pressure control. Background Art

[0002] During the rainy season, heavy rains may fall from time to time, increasing the rainfall in various regions and thus raising the water level in the reservoir. If the water in the reservoir is not drained in time, the dam will be subjected to excessive water pressure, thereby reducing the service life of the dam. When the gate needs to be opened to drain the water from the reservoir, the staff needs to start the drive assembly to lift the gate of the reservoir to open the gate of the reservoir for drainage. However, this method cannot achieve instant control of the water pressure in the reservoir and requires manual drainage of the water pressure in the reservoir, which reduces the labor intensity of the staff. If the staff does not observe the water level of the reservoir in time and cannot release the pressure in time, the dam will be subjected to excessive water pressure, thereby reducing the service life of the dam. The existing gate water pressure control cannot achieve autonomous pressure relief, which reduces the convenience of use. Summary of the invention

[0038] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig.13 and Fig.14 In the figure, baffles 51 are fixedly provided on both sides of the gate 6 located at the upstream side, and an inclined plate 52 is fixedly provided on one side of the baffle 51.

[0039] When using the reservoir drainage gate based on water pressure control: first, the gate 6 is in a closed state. When the water level upstream of the reservoir rises, the water pressure upstream of the reservoir becomes larger. When the water level upstream of the reservoir reaches the point where pressure relief is required, the water in the reservoir needs to be discharged in time. In the device, a drain port 9 is provided above the gate 6. When the water level upstream reaches the drain port 9, if the water level in the reservoir is still rising, the rising water will flow into the downstream of the other side of the gate 6 through the drain port 9 provided on the gate 6, and flow into The water on the other side of the gate 6 will be blocked and intercepted by the intercepting plate 11 installed downstream, so that the water overflowing from the drain port 9 can be collected. During installation, the downstream side of the base 1 is set as an inclined surface, and the intercepting plate 11 is set on the inclined surface. When the intercepting plate 11 continuously intercepts and blocks the overflowing water, the collected and intercepted water will push the intercepting plate 11, so that the intercepting plate 11 slides on the guide rod 12 along the inclined surface. While sliding, the intercepting plate 11 will pull the positioning component to release the positioning of the rotating shaft 7.

[0040] When the intercepting plate 11 slides in the downstream direction, the fixed block 19 on the intercepting plate 11 moves synchronously. The movement of the fixed block 19 will pull the column 18 at one end of the pull rod 17, and the column 18 will slide inside the strip groove 20 during the pulling process. Since the intercepting plate 11 slides obliquely and the pull rod 17 slides horizontally, the column 18 will be displaced inside the strip groove 20 and in the vertical direction of the strip groove 20. The fixed block 19 can drive the pull rod 17 to move while pulling the column 18. A positioning rod 15 is fixed at one end of the pull rod 17, which can drive the positioning rod 15 to move synchronously in the downstream direction, so that the positioning rod 15 slides inside the cross column 13, and one end of the positioning rod 15 is separated from the positioning hole 8 on one side of the rotating shaft 7, and is pulled out from the inside of the shaft groove 4. At this time, the positioning rod 15 and the positioning hole 8 can be realized. Separation, at this time, the positioning rod 15 no longer causes positioning constraints on the rotating shaft 7. When the positioning rod 15 slides in the cross column 13, the limit blocks 16 on both sides of the positioning rod 15 will slide in the limit grooves 14, which can increase the stability of the sliding of the positioning rod 15. By preventing the positioning rod 15 from being pulled out of the cross column 13, the sliding safety of the positioning rod 15 is increased; when the fixed block 19 moves to the downstream side, at this time, the fixed block 19 can push the push plate 28 on one side, so that the slider 29 on one side of the push plate 28 slides inside the slide rail 54, and the movement of the push plate 28 can pull the movable rod 26 to move through the L-shaped rod 27. The movable rod 26 is rotatably connected to one side of the triangular plate 22, so that the triangular plate 22 can be pulled. At the same time, one side of the triangular plate 22 is rotatably connected to one side of the gate pier 2 through the rotating rod 23, so that the triangular plate 22 rotates around the rotating rod 23.

[0041] After the positioning rod 15 is pulled out from the positioning hole 8, the rotating shaft 7 is no longer constrained by the positioning rod 15. At this time, the gate 6 will rotate inversely with the rotating shaft as the center. Since the water level of the reservoir is high and pressure relief is required, the water pressure above the rotating shaft 7 and located on the upstream side of the gate 6 is greater than the water pressure on the side of the gate 6 below the rotating shaft 7. At this time, the water pressure on the side above the rotating shaft 7 pushes the gate 6 to rotate toward the downstream side with the rotating shaft 7 as the center, so that the gate 6 can be opened. When the gate 6 is opened, the baffles 51 on both sides of the gate 6 can block the gap between the side of the gate 6 and the gate pier 2, reducing the flow of floating objects from the gap between the two to the downstream. At the same time, when the gate 6 rotates, it rotates at the gap 3. At this time, the inclined plate 52 on one side of the baffle 51 can block the gate 6 between the gap 3 and reduce the flow of floating objects from the gap between the two to the downstream.

[0042] After the gate 6 is pushed open by the water pressure above the rotating shaft 7, the guide columns 10 on both sides of the gate 6 slide inside the arc track 5, which can increase the stability of the gate 6 opening. When the guide columns 10 slide inside the arc track 5, one end of the guide columns 10 extending from the arc track 5 can squeeze and push the pressure plate 25 at one end of the tilted triangular plate 22, so that the triangular plate 22 rotates again with the rotating rod 23 as the center. When the triangular plate 22 rotates, it can continuously push the L-shaped rod 27 through the movable rod 26, so that the push plate 28 continues to slide on one side of the slide rail 54. When the guide column 10 slides to the other end of the arc track 5, the guide column 10 can press the pressure plate 25, and the triangular plate 22 stops rotating, and the push plate 28 stops sliding on one side of the slide rail 54.

[0043] When the guide column 10 slides to the other end of the arc rail 5, the second wedge block 33 at the end of the reset push rod 30 on one side of the gate 6 contacts the hypotenuse of the trapezoidal block 37 respectively. At this time, the hypotenuse of the trapezoidal block 37 can push the second wedge block 33, so that the reset push rod 30 slides inside the sleeve 31, and the first wedge block 32 at the other end of the reset push rod 30 penetrates into the bottom of the arc rail 5 and aligns with the pressing groove 24, waiting for the gate 6 to rotate in the opposite direction to push the pressing groove 24.

[0044] After the gate 6 is pushed open by the water pressure above the rotating shaft 7, the lower end of the gate 6 is separated between the base 1 to produce a pressure relief channel. At this time, the upstream water will flow into the downstream through the pressure relief channel there, realizing the effect of upstream downward pressure. At the same time, when the gate 6 is rotated to open with the rotating shaft 7, the pressure relief channel is located on the side of the base 1 and the lower end of the gate 6 and is located in the water. Floating objects floating above the water surface will be intercepted by the gate 6 and located above the water surface of the inclined surface of the gate 6. Then, they will be salvaged by the auxiliary salvaging component, so as to avoid the pressure relief channel being located above the water surface, causing the floating objects to follow the water flow through the gate and accumulate at the gate, thereby affecting the blockage of the gate, thereby improving the smoothness of drainage through the pressure relief channel.

[0045] The water from the upstream of the reservoir is discharged into the downstream through the pressure relief channel. Continuous drainage and pressure relief will cause the water level of the upstream reservoir to drop. The drop in water level will cause the water pressure on the upstream side of the gate 6 at the end above the rotating shaft 7 to gradually decrease. The gate 6 is pushed by the water pressure below the rotating shaft 7, so that the gate 6 will rotate in the opposite direction around the rotating shaft 7, so that the gate 6 is gradually closed. When the water pressure on the side of one end of the gate 6 below the rotating shaft 7 is greater than the water pressure on the side of one end of the gate 6 above the rotating shaft 7, the gate 6 is pushed to reverse by the water pressure at the lower end, and the gate 6 contacts one side of the gate pier 2, so that the gate 6 can be closed.

[0046] When the gate 6 is gradually closed in the reverse direction, the guide posts 10 on both sides of the gate 6 slide inside the arc track 5 as the gate 6 reverses, and at the same time, the gate 6 drives the first wedge block 32 extending to the bottom of the arc track 5 to move synchronously. After the gate 6 drives the first wedge block 32 to fit into the pressing groove 24 on one side of the triangular plate 22, the gate 6 continues to rotate in the reverse direction, driving the reset push rod 30 and the first wedge block 32 to move synchronously. At this time, the first wedge block 32 can push the triangular plate 22 in the reverse direction, so that the triangular plate 22 rotates in the reverse direction with the rotating rod 23 as the center of the circle. At the same time, the L-shaped rod 27 is pulled in the reverse direction by the movable rod 26, so that the L-shaped rod 27 pulls the push plate 28 to slide to the upstream side. When the push plate 28 moves to one side of the fixed block 19, it can push the fixed block 19, so that the fixed block 19 moves to the side close to the gate 6. The movement of the fixed block 19 can drive the intercepting plate 11 to move synchronously, so that the intercepting plate 11 When the gate 6 is closed, the positioning rod 15 is pushed into the shaft groove 4 and inserted into the positioning hole 8 on one side of the shaft 7, so that the shaft 7 can be re-positioned, waiting for the next pressure relief unlocking. When the gate 6 is closed, the first wedge block 32 slides out of the pressing groove 24, so that the first wedge block 32 is separated from the pressing groove 24, and the first wedge block 32 contacts with the stopper 34, which will cause the first wedge block 32 to slide on the inclined surface 35 of the stopper 34, so that the first wedge block 32 is pushed to one side of the gate 6, and the reset push rod 30 is reset, waiting for the next extension use. This action can realize the positioning of the shaft 7, increase the positioning of the gate 6 by the shaft 7, and realize the stability of the gate 6 closing when the reservoir does not need pressure relief.

[0047] The device has a simple structure. By adding a drain port 9, a rotating shaft 7, a positioning hole 8, a diverter plate 11, and a positioning component and a reset component, the gate 6 can be opened and closed by the water pressure of the reservoir, thereby realizing automatic water pressure control of the reservoir, avoiding the staff from opening the gate 6 to release pressure after observing the water level of the reservoir, and effectively reducing the labor intensity of the staff. The device can automatically open the gate 6 when drainage is required, and automatically close the gate 6 after pressure relief, thereby realizing the convenience of reservoir water pressure control, and can timely relieve pressure on the reservoir, thereby avoiding the problem of shortening the service life of the dam due to excessive water pressure on the dam, realizing autonomous pressure relief of reservoir water pressure control, and improving convenience of use.

[0049] See also Figure 1 , Figure 2 and Figure 13-Figure 15 The auxiliary salvage assembly shown in the figure includes a crawler 38 provided on one side of the gate 6, crawler wheels 39 are meshed on the inner sides of both ends of the crawler 38, and a stop plate 40 is fixedly provided at an equal distance on one side of the crawler 38, wherein first transmission teeth 41 are fixedly provided on both sides of the crawler wheel 39 located on the upper side of the gate 6, and the first transmission teeth 41 are connected to the driving assembly;

[0050] See also Figure 4 , Fig.13 and Fig.15The driving assembly shown in the figure includes an impeller 42 arranged on the lower end side of the gate 6, and a first gear 43 is fixedly provided at both ends of the impeller 42. A second gear 44 is provided on the upper side of the gate 6. The first gear 43 and the second gear 44 are meshed and connected by a toothed chain 45. A second transmission tooth 46 meshed and connected to the first transmission tooth 41 is fixedly provided on one side of the second gear 44.

[0051] In the present embodiment, an auxiliary salvage component is installed on the upstream side of the gate 6 to salvage floating objects floating on the water surface on the upstream side of the reservoir, thereby reducing congestion and accumulation of floating objects at the gate and achieving smooth drainage of the gate. At the same time, a driving component is provided on the downstream side of the gate 6, which can convert the kinetic energy of the water flow into mechanical energy to drive the auxiliary salvage component when the gate 6 is opened to release pressure, and can reasonably utilize the kinetic energy of the water, reducing the use of driving equipment. At the same time, the auxiliary salvage component can be automatically driven when the gate 6 is opened, thereby increasing the convenience of use.

[0052] In specific use, after the water pressure on the upstream side of the gate 6 reaches the drain port 9, the water in the upstream reservoir will flow into the downstream through the drain port 9, and the intercepting plate 11 at the downstream can intercept the flowing water. When the intercepting plate 11 intercepts the water and can push it, the intercepting plate 11 will slide along the guide rod 12. When the intercepting plate 11 is displaced, the positioning assembly is separated from the positioning hole 8 on the side of the rotating shaft 7 to unlock the rotating shaft 7. Since the upstream water pressure is large and the water pressure on the side above the rotating shaft 7 is greater than the water pressure on the side below the rotating shaft 7, the water pressure upstream and above the rotating shaft 7 can push the gate 6, so that the gate 6 rotates along the rotating shaft 7 to open the gate 6. At this time, one end of the bottom of the gate 6 is separated from the base 1, and the upstream water will flow downstream through this place.

[0053] The water in the upstream can push the impeller 42 at the downstream end of the gate 6 during the flow, so that the impeller 42 rotates, and the flowing water energy can be reasonably utilized. The rotation of the impeller 42 can drive the first gears 43 on both sides to rotate. The first gear 43 and the second gear 44 on the upper side of the gate 6 are meshed and transmitted through the tooth chain 45, that is, the second gear 44 is driven to rotate through the meshing of the tooth chain 45 while the first gear 43 rotates. The rotation of the second gear 44 can drive the second transmission gear 46 on one side to rotate. Since the second transmission gear 46 is meshed and connected with the first transmission gear 41, the second transmission gear 46 is meshed and connected with the first transmission gear 41. When the first transmission gear 41 rotates, the first transmission gear 41 can be driven to rotate, and the first transmission gear 41 is fixedly installed on both sides of one of the track wheels 39, and a track 38 is provided between the track wheels 39 at both ends of the gate 6, which can drive the track 38 to move on the upstream side of the gate 6. When the track moves on one side of the gate 6, it can salvage floating objects floating on the upstream water surface, avoid clogging the gate by floating objects, increase the cleaning of floating objects at the gate when the reservoir is opened, avoid manual salvage using salvage tools, effectively reduce the labor intensity of the staff, and improve the convenience of salvaging floating objects on the water surface at the gate.

[0054] After the gate 6 is opened and the reservoir is pressed down, the water level upstream of the reservoir drops, which will change the pressure on the gates 6 on both sides of the rotating shaft 7. While the water pressure above the rotating shaft 7 gradually decreases, the gate 6 gradually rotates in the opposite direction. At this time, the inclination angle of the gate 6 can be changed. Similarly, the water level on the upstream side of the gate 6 drops, and the floating objects intercepted on the side of the gate 6 also drop. At this time, the auxiliary salvage component on one side of the gate 6 can adapt its height to salvage floating objects at different water levels, which increases the convenience of salvaging floating objects and can make reasonable use of the water energy flowing upstream of the reservoir.

[0055] When the water pressure on the gate 6 below the shaft 7 is greater than the water pressure on the gate 6 above it, the gate 6 closes automatically. At this time, the reset assembly can push the positioning assembly to allow the positioning assembly to position and restrain the shaft 7 again to prevent the shaft 7 from rotating again. When the next upstream water level passes the drain port 9, the positioning assembly can be dragged again to unlock the shaft 7, release the pressure again, and salvage floating objects on the upstream water surface again, thereby achieving convenience of use.
