Description

Technical Field

[0001] The present invention relates to the field of water conservancy stop gates, and specifically to a water stop device for water conservancy project construction. Background Technique

[0002] Water conservancy gates are commonly used water stop and flow discharge water conservancy project devices, which are used for hydropower station power generation, river regulation, reservoir regulation, etc. Gates have a wide range of applications in water conservancy projects and are important facilities for ensuring water resource utilization and water conservancy safety. Water conservancy gates are mainly divided into three parts: the fixed buried part, the movable part of the gate body, and the hoisting equipment. The movable part of the gate body is embedded in the fixed buried part, and the hoisting equipment is used to lift and adjust the movable part of the gate body, so as to control the opening and closing of the gate, the size of the opening and closing, etc.

[0003] Since the inner wall of the fixed buried part of the existing water conservancy gate is usually in the shape of a C-shaped opening, that is, it can allow the movable part of the gate body to be embedded in the fixed buried part and play a limiting role on the movable part of the gate body. However, for the current water conservancy project water stop device, in the early stage, it is necessary to dig guide grooves on both sides of the river channel and lay guide walls and other work to facilitate the lifting of the gate, which increases the workload of the installation and construction of the existing water stop device and further prolongs the construction progress; in addition, the existing water stop device discharges or stops the flow by lifting and lowering the gate. During the opening of the gate to release water, the gravel rolled up by the river water is likely to remain at the bottom of the river channel. When the gravel is located below the gate, when the movable main part of the gate is closed, it cannot be closed tightly and is prone to water seepage. Summary of the Invention

Detailed implementation manners

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 18, the present invention provides a technical solution: a water stop device for water conservancy project construction, including an installation frame 1. A power cylinder 2 is fixedly installed on the top of the installation frame 1. It should be noted here that the width of the installation frame 1 is greater than the width of the gate 3, and the installation frame 1 can be fixedly installed on the cement platforms on both sides of the dam. The output end of the power cylinder 2 is provided with a gate 3. The bottom of the gate 3 is hinged with a movable gate plate 4. It should be added here that U-shaped blocks are symmetrically hinged at the lower end of the gate 3 on the water-blocking side, and an L-shaped movable block is hinged on the U-shaped block. The lower end of the L-shaped movable block is fixedly installed on the upper surface of the movable gate plate 4, so that the movable gate plate 4 can be flipped at the lower end of the gate 3, and the U-shaped block and the U-shaped bracket 705 are at the same height. A sealing mechanism 5 for improving the sealing at both ends of the gate 3 is arranged between the side of the gate 3 away from the water-blocking side and the output end of the power cylinder 2. A U-shaped airbag 6 is fixedly installed at the bottom of the movable gate plate 4, and a flipping mechanism 7 for folding the movable gate plate 4 is arranged between the inside of the U-shaped airbag 6 and the output end of the power cylinder 2. A gas storage assembly 8 is arranged between one side of the flipping mechanism 7 and the inside of the movable gate plate 4. An inflation assembly 9 is arranged between one end of the gas storage assembly 8 and the bottom of the movable gate plate 4.

[0021] In this embodiment, as Figures 1 to 18 shown, the sealing mechanism 5 includes a first movable groove 501. The first movable groove 501 is opened on the side of the gate 3 away from the water-blocking side. A connecting block 502 is fixedly installed at the output end of the power cylinder 2, and a pull rod 503 is fixedly installed on one side of the bottom of the connecting block 502. The pull rod 503 is located in the first movable groove 501. Tapered blocks 504 are symmetrically fixedly installed on the surface of the pull rod 503, and movable rods 505 are symmetrically arranged on both sides of the tapered blocks 504. The movable rods 505 are horizontally movably penetrated through the inside of the gate 3. T-shaped grooves 303 are opened at both ends of the gate 3. A T-shaped rubber sealing plate 506 is fixedly connected between one ends of the two movable rods 505 on the same side, and the T-shaped rubber sealing plate 506 is movably installed in the T-shaped groove 303. The other end of the movable rod 505 is placed on the surface of the tapered block 504. It should be added that the other end of the T-shaped rubber sealing plate 506 is provided with an inclined surface that matches the tapered surface of the tapered block 504, which reduces interference when the tapered block 504 moves downward to squeeze and push the movable rod 505. A positioning ring 507 is fixedly connected to the surface of the other end of the movable rod 505. A first spring 508 is sleeved on the surface of the other end of the movable rod 505, and both ends of the first spring 508 are respectively fixedly installed on one side of the positioning ring 507 and the inner wall of the first movable groove 501. Limit blocks 509 are symmetrically penetrated through the surface of the pull rod 503, and the side walls of the limit blocks 509 are fixedly installed on the inner wall of the first movable groove 501. The flipping mechanism 7 is arranged between the other side of the bottom of the connecting block 502 and the inside of the U-shaped airbag 6.

[0022] When the output end of the electric cylinder 2 drives the pull rod 503 at the bottom of the connecting block 502 to rise, first, the tapered block 504 fixed on the pull rod 503 releases the extrusion on the corresponding movable rod 505. Under the elastic reset of the first spring 508, the movable rod 505 drives the T-shaped rubber sealing plate 506 to contract into the T-shaped groove 303, and the T-shaped rubber sealing plate 506 releases the sealing of the river channel side wall. At the same time, the guide wheel 302 is exposed to the erected river channel side wall. Then, when the pull rod 503 drives the tapered block 504 to continue to move upward, when the first piston rod 701 at the bottom of the connecting block 502 moves to the top wall of the piston cylinder 702, the tapered block 504 also moves and abuts against the bottom of the corresponding limit block 509. While the tapered block 504 drives the limit block 509 on the gate 3 to move upward, the first piston rod 701 pulls the piston cylinder 702 upward, so that the gate 3 rises smoothly under the pulling of the pull rod 503 and the first piston rod 701 to open the gate.

[0023] In this embodiment, as Figures 1 to 18 shown, a number of balls are equidistantly arranged in a circumferential array on the surface of the movable rod 505, and one side of the balls abuts against the inner wall of the gate 3. Through the arrangement of the balls, the friction between the movable rod 505 and the inner wall of the gate 3 can be reduced, the interference between the two can be reduced, and the stability of the movement of the movable rod 505 can be improved.

[0024] In this embodiment, as Figures 1 to 18 shown, a first rubber sealing strip is symmetrically and fixedly installed on one side of the inner wall of the T-shaped groove 303, and a second rubber sealing strip matching the first rubber sealing strip is symmetrically and fixedly installed on one side of the T-shaped rubber sealing plate 506. After the movable rod 505 drives the corresponding T-shaped rubber sealing plate 506 to move in place in the T-shaped groove 303, the second rubber sealing strip on the T-shaped rubber sealing plate 506 closely adheres to the first rubber sealing strip to improve the sealing between the two ends of the gate 3.

[0025] In this embodiment, as Figures 1 to 18 shown, U-shaped reinforcing ribs 601 are fixedly installed around the inner wall of the U-shaped airbag 6, a number of hinge rods 602 are equidistantly hinged between adjacent two U-shaped reinforcing ribs 601, and a pin shaft is rotatably installed between adjacent two hinge rods 602. Third sealing strips 603 are fixedly installed on both sides of the upper end of the U-shaped airbag 6, and one side of the third sealing strip 603 abuts against the surface of the adjacent T-shaped rubber sealing plate 506.

[0026] Through the arrangement of the U-shaped reinforcing ribs 601 and the hinge rods 602 on the inner wall of the U-shaped airbag 6, when expanding and contracting, the unfolding direction and shape of the airbag after inflation are guided to make it fit more closely to both sides of the dam. After the U-shaped airbag 6 is fully unfolded, the third sealing strip 603 on the U-shaped airbag 6 closely abuts against the surface of the T-shaped rubber sealing plate 506 to improve the sealing between the U-shaped airbag 6 and the T-shaped rubber sealing plate 506.

[0027] In this embodiment, as Figures 1 to 18 shown, the flipping mechanism 7 includes a first piston rod 701. The first piston rod 701 is fixedly installed on the other side of the bottom of the connecting block 502. The upper end of the first piston rod 701 movably penetrates through the bottom of the mounting frame 1. The lower end of the first piston rod 701 is movably installed with a piston cylinder 702. And a first telescopic hose 703 is fixedly installed at the bottom of the piston cylinder 702. A first connection hole 401 is opened on one side inside the movable gate 4. And one end of the first connection hole 401 communicates with the inside of the U-shaped airbag 6. One end of the first telescopic hose 703 is fixedly connected to the other end of the first connection hole 401. A one-way valve 704 is installed inside the other end of the first telescopic hose 703. The middle of the lower end of the gate 3 is fixedly connected with a U-shaped bracket 705. And an L-shaped hinge plate 706 is rotatably installed on the U-shaped bracket 705. And one side of the L-shaped hinge plate 706 is fixedly installed on the surface of the movable gate 4. Both ends of the L-shaped hinge plate 706 are fixedly connected with mounting blocks 707. One end of the mounting block 707 is rotatably installed with a roller 709. The outer wall of the lower end of the piston cylinder 702 is symmetrically and fixedly installed with mounting plates 708. And a guide groove 7081 is opened at the lower end of the mounting plate 708. The upper end of the guide groove 7081 is perpendicular to the gate 3, and the lower end is inclined. The roller 709 is rollingly installed in the adjacent guide groove 7081. The air storage assembly 8 is arranged between the inside of the lower end of the piston cylinder 702 and the movable gate 4.

[0028] When the output end of the electric cylinder 2 drives the connecting block 502 to move upward to open the gate 3, first, the connecting block 502 drives the first piston rod 701 to rise. Through the cooperation of the first piston rod 701 and the piston cylinder 702, an air extraction effect is generated. At this time, the one-way valve 704 is in an open state. The air inside the U-shaped airbag 6 is pumped into the piston cylinder 702 through the first connection hole 401 and then through the first telescopic hose 703. And during the upward movement of the first piston rod 701, the roller 709 moves vertically in the guide groove 7081. At this time, the L-shaped hinge plate 706 does not deflect. When the first piston rod 701 rises to the top wall of the piston cylinder 702, at this time, the roller 709 moves to the inclined surface at the lower end of the guide groove 7081. By pulling the piston cylinder 702 to continue rising through the first piston rod 701, at this time, the piston cylinder 702 drives the two side mounting plates 708 to move upward, causing the roller 709 to deflect through the inclined surface at the lower end of the guide groove 7081. At this time, the mounting block 707 drives the L-shaped hinge plate 706 to turn up with the hinge point of the U-shaped bracket 705 as the axis. While the gate 3 moves upward, the movable gate 4 is turned over, so that the movable gate 4 and the gate 3 cooperate to form a gradually changing water flow channel, avoiding violent turbulence caused by sudden contraction or expansion of the water flow, reducing the instantaneous impact on the gate and the downstream structure, and further improving the safety of the water stop device of the water conservancy project when opening the gate.

[0029] In this embodiment, as Figures 1 to 18As shown, the gas storage component 8 includes a second telescopic hose 801, which is fixedly mounted on one side of the lower end of the piston cylinder 702, and a gas storage bin 802 is provided in the horizontal direction inside the movable gate plate 4, and one end of the second telescopic hose 801 is connected to the inside of the gas storage bin 802, and a second piston rod 803 is movably mounted inside the gas storage bin 802, and a second spring 804 is sleeved on the surface of one end of the second piston rod 803, and the two ends of the second spring 804 are respectively fixedly mounted on the inner wall of the gas storage bin 802 and the surface of one end of the second piston rod 803, and one end inside the gas storage bin 802 is fixedly connected to a limiting ring 8021. It should be added here that, through the setting of the limiting ring 8021, the second piston rod 803 is prevented from blocking the airway between one end of the second telescopic hose 801 and the air storage bin 802, thereby affecting the connectivity of the airway. One end of the second piston rod 803 is arranged on one side of the limiting ring 8021, and a second connecting hole 402 is provided on the other side of the movable gate plate 4. One end of the second connecting hole 402 is connected to the interior of the U-shaped airbag 6, and the other end of the second connecting hole 402 is connected to the interior of the air storage bin 802. The inflation assembly 9 is arranged between the lower end of the movable gate plate 4 and the interior of the air storage bin 802.

[0030] When the gate is closed, when the electric cylinder 2 drives the first piston rod 701 to slowly descend, the gate 3 and the movable gate plate 4 hinged at the bottom always pull the piston cylinder 702 due to their own weight, so that the bottom of the first piston rod 701 keeps in contact with the top wall of the piston cylinder 702. At this time, the movable gate plate 4 will not flip over. When the gate 3 is lowered into place, the output end of the electric cylinder 2 pushes the first piston rod 701 at the bottom of the connecting block 502 to continue to descend, so that the first piston rod 701 squeezes the air in the piston cylinder 702. At this time, the one-way valve 704 is in a closed state, so that the air enters the air storage bin 802 through the second telescopic hose 801 for storage. After the air enters the air storage bin 802, the second piston rod 803 moves in the direction away from the blocking block 902 due to the increase of air inside the air storage bin 802, and at the same time, the second spring 804 is squeezed and contracted by the force. At the same time, when the first piston rod 701 squeezes the air in the piston cylinder 702, the piston cylinder 702 drives the mounting plates 708 on both sides to move downward, so that the roller 709 in the guide groove 7081 drives the mounting block 707 to roll in the inclined groove at the lower end of the guide groove 7081. At this time, the mounting block 707 drives the L-shaped hinged plate 706 to flip, so that the L-shaped hinged plate 706 drives the movable gate plate 4 to fold downward. During the folding of the movable gate plate 4, the gravel at the bottom of the river channel can be pushed away from the bottom of the gate 3, avoiding the problem of loose closure after the bottom of the movable gate plate 4 is folded into place.

[0031] In this embodiment, Figures 1 to 18As shown in the figure, the inflation assembly 9 includes a second movable slot 901 which is opened inside the movable shutter 4. The interior of the second movable slot 901 communicates with the interior of the air storage chamber 802. A blocking block 902 is movably installed inside the second movable slot 901. A through hole 903 is horizontally opened at the lower end of the blocking block 902. A connecting rod 904 is fixedly connected to the bottom of the blocking block 902 and penetrates to the bottom of the movable shutter 4. An installation slot 905 is opened at the bottom of the movable shutter 4. A pressing block 906 is fixedly connected to the bottom of the connecting rod 904. A third spring 907 is sleeved on the surface of the lower end of the connecting rod 904, and the two ends of the third spring 907 are respectively fixedly installed between the top wall of the installation slot 905 and the top of the pressing block 906. A rubber ring 9021 is fixedly installed at the bottom of the blocking block 902, and the bottom of the rubber ring 9021 is placed on the bottom wall of the second movable slot 901.

[0032] It should be noted here that the pressing block 906 is triangular, and the lower part of the pressing block 906 is on the water-blocking side. When the movable shutter 4 is folded down and reset, after the movable shutter 4 is completely folded in place, the air stored in the air storage chamber 802 flows into the U-shaped airbag 6 through the through hole 903 from the second connection hole 402. The U-shaped airbag 6 is inflated and expanded to complete the sealing of both ends and the bottom of the movable shutter 4 against the river dam. In addition, the rubber ring 9021 improves the sealing performance inside the second movable slot 901, and the surface of the blocking block 902 fits closely with the inner wall of the second movable slot 901 to enhance the sealing effect.

[0033] When the movable shutter 4 is about to complete the closing in the vertical state, due to the setting of the pressing block 906 at the bottom of the movable shutter 4, the lower part of the bottom of the pressing block 906 presses on the bottom of the river channel, causing the pressing block 906 to drive the blocking block 902 on the connecting rod 904 to rise. At this time, the through hole 903 at the lower end of the blocking block 902 communicates with the interior of the air storage chamber 802, enabling the air in the air storage chamber 802 to flow into the U-shaped airbag 6 through the second connection hole 402. Under the elastic reset of the second spring 804, the air in the air storage chamber 802 can quickly squeeze into the U-shaped airbag 6, causing the U-shaped airbag 6 to expand, so that the expansion of the U-shaped airbag 6 realizes the sealing of both sides and the bottom of the movable shutter 4 against the river channel. At the same time, the pull rod 503 at the bottom of the connecting block 502 drives the conical block 504 to squeeze and push the corresponding movable rod 505, causing the movable rod 505 to drive the T-shaped rubber sealing plate 506 to approach the side wall of the river channel and closely adhere to the side wall of the river channel to prevent river water from leaking from both ends of the gate 3 and around the movable shutter, solving the problems of the existing water stop device that requires work such as digging guide grooves and laying guide walls on both sides of the river channel in the early stage, thereby increasing the construction workload and further prolonging the construction progress.

[0034] In this embodiment, as Figures 1 to 18As shown in the figure, guide rods 301 are symmetrically and fixedly installed at the top of the gate 3, and the upper ends of the guide rods 301 extend above the mounting frame 1. A number of guide wheels 302 are fixedly installed at equal intervals at both ends of the gate 3. Through the arrangement of the guide rods 301, the stability of the gate 3 during lifting is improved. Through the arrangement of the guide wheels 302, after the T-shaped rubber sealing plate 506 and the U-shaped airbag 6 contract, the guide wheels 302 contact the side wall of the dam, and the stability of the gate 3 during lifting is further improved during the lifting of the gate 3.

[0035] In this embodiment, as Figures 1 to 18 shown, a first sealing strip 304 is fixedly installed on one side of the bottom wall of the gate 3, and a second sealing strip 403 is fixedly installed on one side of the top wall of the movable gate plate 4, and the second sealing strip 403 abuts against the first sealing strip 304. When the movable gate plate 4 is turned down to the vertical state, the second sealing strip 403 on the top wall of the movable gate plate 4 abuts against the first sealing strip 304 on the bottom wall of the gate 3, improving the sealing performance of the gap between the gate 3 and the movable gate plate 4.

[0036] The usage method and advantages of the present invention: The water stop device for water conservancy project construction is as follows: As Figures 1 to 18 shown, during the opening and closing of the water stop device for water conservancy project construction, when opening the gate, first, the output end of the electric cylinder 2 drives the pull rod 503 on the connecting block 502 to move upward, so that the tapered block 504 fixed on the pull rod 503 releases the extrusion of the corresponding movable rod 505. Under the elastic reset of the first spring 508, the movable rod 505 drives the T-shaped rubber sealing plate 506 to contract into the T-shaped groove 303, and the T-shaped rubber sealing plate 506 releases the sealing of the side wall of the river channel. At the same time, the guide wheels 302 are exposed and erected on the side wall of the river channel. Then, when the pull rod 503 drives the tapered block 504 to continue to move upward, when the first piston rod 701 at the bottom of the connecting block 502 moves to the top wall of the piston cylinder 702, the tapered block 504 also moves and abuts against the bottom of the corresponding limit block 509. While the tapered block 504 drives the limit block 509 on the gate 3 to move upward, the first piston rod 701 pulls the piston cylinder 702 to move upward, so that the gate 3 rises smoothly under the pulling of the pull rod 503 and the first piston rod 701 to open the gate; When the output end of the electric cylinder 2 drives the connecting block 502 to move upward, the connecting block 502 drives the first piston rod 701 to move upward, and the first piston rod 701 cooperates with the piston cylinder 702 to produce a suction effect. At this time, the one-way valve 704 is in an open state, and the air inside the U-shaped airbag 6 is sucked into the piston cylinder 702 through the first connecting hole 401 and the first telescopic hose 703. When the first piston rod 701 moves upward, the roller 709 moves vertically in the guide groove 7081. At this time, the L-shaped hinge plate 706 does not deflect. When the first piston rod 701 rises to the top wall of the piston cylinder 702, the roller 709 moves vertically in the guide groove 7081. At this time, the L-shaped hinge plate 706 does not deflect. When the first piston rod 701 rises to the top wall of the piston cylinder 702, the roller 709 moves vertically in the guide groove 7081. At this time, the L-shaped hinge plate 706 does not deflect. 09 moves to the inclined surface at the lower end of the guide groove 7081, and the piston cylinder 702 continues to rise through the first piston rod 701. At this time, the piston cylinder 702 drives the mounting plates 708 on both sides to move upward, so that the roller 709 deflects through the inclined surface at the lower end of the guide groove 7081. At this time, the mounting block 707 drives the L-shaped hinged plate 706 to fold upward with the hinge of the U-shaped bracket 705 as the axis. When the gate 3 moves upward, the movable gate plate 4 is folded, so that the movable gate plate 4 and the gate 3 work together to form a gradual water flow channel, avoid violent turbulence caused by sudden contraction or expansion of the water flow, and reduce the instantaneous impact on the gate and downstream structures; When the gate is closed, when the electric cylinder 2 drives the first piston rod 701 to slowly descend, the gate 3 and the movable gate plate 4 hinged at the bottom always pull the piston cylinder 702 due to their own weight, so that the bottom of the first piston rod 701 keeps in contact with the top wall of the piston cylinder 702. At this time, the movable gate plate 4 will not flip over. When the gate 3 is lowered into place, the output end of the electric cylinder 2 pushes the first piston rod 701 at the bottom of the connecting block 502 to continue to descend, so that the first piston rod 701 squeezes the air in the piston cylinder 702. At this time, the one-way valve 704 is in a closed state, so that the air enters the air storage bin 802 through the second telescopic hose 801 for storage. After the air enters the air storage bin 802, the second piston rod 803 moves in the direction away from the blocking block 902 due to the increase of air inside the air storage bin 802, and at the same time, the second spring 804 is squeezed and contracted by force. At the same time, when the first piston rod 701 squeezes the air in the piston cylinder 702, the piston cylinder 702 drives the mounting plates 708 on both sides to move downward, so that the roller 709 in the guide groove 7081 drives the mounting block 707 to roll in the inclined groove at the lower end of the guide groove 7081. At this time, the mounting block 707 drives the L-shaped hinged plate 706 to flip, so that the L-shaped hinged plate 706 drives the movable gate plate 4 to fold downward. When the movable gate plate 4 is folded, the gravel at the bottom of the river channel can be pushed away from the bottom of the gate 3, avoiding the problem of loose closure after the bottom of the movable gate plate 4 is folded into place; When the movable gate 4 is about to complete the closing in the vertical state, through the setting of the extrusion block 906 at the bottom of the movable gate 4, the lower part of the bottom of the extrusion block 906 is extruded on the bottom of the river channel, so that the extrusion block 906 drives the plugging block 902 on the connecting rod 904 to rise. At this time, the through hole 903 at the lower end of the plugging block 902 is communicated with the inside of the air storage chamber 802, so that the air in the air storage chamber 802 flows into the U-shaped airbag 6 through the second connection hole 402. Under the elastic reset of the second spring 804, the air in the air storage chamber 802 can be quickly squeezed into the U-shaped airbag 6, so that the U-shaped airbag 6 unfolds, and the expansion of the U-shaped airbag 6 realizes the plugging of the two sides and the bottom of the movable gate 4 to the river channel; Meanwhile, the pull rod 503 at the bottom of the connecting block 502 drives the conical block 504 to squeeze and push the corresponding movable rod 505, so that the movable rod 505 drives the T-shaped rubber sealing plate 506 to approach the side wall of the river channel and closely adhere to the side wall of the river channel to prevent river water from leaking from both ends of the gate 3 and around the movable gate.
