[0002] Hydraulic gates are control facilities used to close and open discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. In water conservancy projects, hydraulic gates are often needed to control the water storage capacity of rivers, canals and reservoirs.

[0003] The hydraulic gate includes a gate frame and a main gate. The main gate is slidably arranged on the gate frame in a vertical direction. A driving assembly is arranged on the gate frame. The driving assembly includes a motor installed on the gate frame, a lead screw vertically inserted on the gate and threadedly connected to the gate, the lead screw is coaxially arranged with the motor output shaft and fixedly connected with the motor output shaft. When the hydraulic gate is in use, a large amount of silt is easily accumulated between the bottom wall of the gate frame and the main gate. The silt causes a gap between the main gate and the bottom wall of the gate frame, resulting in water leakage.

[0004] In the prior art, a water conservancy gate intelligent system disclosed in publication number "CN115450181B" relates to the technical field of water conservancy gates, which includes a mounting assembly, a baffle plate slidably arranged on the mounting assembly in a vertical direction, a cleaning assembly arranged on the baffle plate, and a driving assembly arranged on the mounting assembly and used to drive the baffle plate to move in a vertical direction. The baffle plate is arranged vertically, and the cleaning assembly is used to remove impurities under the baffle plate. The present application can improve the sealing performance of the water conservancy gate.

[0019] A method, based on the above-mentioned high-sealing hydraulic gate, comprises the following steps:

[0020] S1: When in use, the engineering personnel first build the bottom gate body into the water conservancy canal. The water flow inside the water conservancy canal will enter the bottom gate body through the waterway in the gate body. After the water flows continuously through the waterway in the gate body, silt will be deposited inside the waterway in the gate body. When it is necessary to open, close and seal the waterway in the gate body inside the bottom gate body, it is necessary to discharge the silt in the gate body door buckle area at the bottom of the gate frame;

[0021] S2: The electric-driven impeller on the overdriven side plate rotates. When the electric-driven impeller contacts the water flow entering from the water inlet, it rotates and accelerates the water flow, so that the water flow quickly impacts the silt accumulated on the surface area of ​​the flexible diaphragm. When the silt on the surface of the flexible diaphragm is washed away, the buckling and sealing effect of the bottom of the gate can be effectively guaranteed;

[0022] S3: The top plug-in block at the bottom of the gate body will slowly insert into the surface of the flexible diaphragm during the descent process. The top plug-in block pushes the flexible diaphragm to fit into the bottom slot between the bottom plug-in blocks during the continuous insertion process. Then, the top plug-in block, the flexible diaphragm and the bottom plug-in block fit tightly together, thereby further improving the buckling and sealing effect at the bottom of the gate body;

[0023] S4: The gas in the air chamber can be injected into the installation cavity through the electromagnetic air valve to increase the air pressure inside the installation cavity. The increased air pressure inside the installation cavity pushes the flexible diaphragm to fit tightly to the bottom of the top plug block, further improving the sealing performance of the bottom of the gate body.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When in use, when the waterway in the gate body is flowing normally, the electromagnetic air valve injects the gas inside the air chamber into the installation cavity. The increase in air pressure inside the installation cavity will fully inflate the flexible diaphragm part, causing the flexible diaphragm part to expand and produce an arc-shaped bulge. When the water body continues to flow through the arc-shaped bulge, the silt is blocked on one side of the flexible diaphragm, avoiding the accumulation of a large amount of silt on the surface of the flexible diaphragm and reducing the amount of silt accumulation at the bottom of the gate;

[0026] 2. When in use, the upper water flow on one side of the waterway in the gate body connected to the water inlet area will be injected from the other side of the partition cover through the water inlet hole, and the sediment filter plate will block the sand and stones in the water flow, and then drive the electric drive impeller on the side plate to rotate. When the electric drive impeller contacts the water flow entering from the water inlet hole, it will rotate and accelerate the water flow, so that the water flow quickly impacts the silt accumulated on the surface area of ​​the flexible diaphragm. When the sediment on the surface of the flexible diaphragm is washed away, the buckling and sealing effect of the bottom of the gate can be effectively guaranteed;

[0027] 3. When in use, the moving block drives the gate door to descend through the moving rod. The top plug-in block at the bottom of the gate door will slowly insert into the surface of the flexible diaphragm during the descent process. The top plug-in block pushes the flexible diaphragm to fit into the bottom slot between the bottom plug-in blocks during the continuous insertion process. Then the top plug-in block, the flexible diaphragm and the bottom plug-in block fit tightly together, thereby further improving the buckling and sealing effect of the bottom of the gate door.

[0043] The following will be combined with the drawings in the embodiments 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.

[0044] See also Figure 1-8 , the present invention provides a technical solution:

[0045] Embodiment 1: A high-sealing hydraulic gate: comprising a bottom gate body 1, a gate frame 3 and a mounting frame 4, wherein a gate body waterway 11 is arranged inside the bottom gate body 1, and a mounting cavity 14 is arranged inside the gate body waterway 11, the gate frame 3 is vertically arranged at the top of the gate frame 3, the gate frame 3 is mounted on the top of the bottom gate body 1, the mounting frame 4 is arranged at one side of the gate frame 3, and the mounting frame 4 is mounted on the top of the bottom gate body 1;

[0047] Vertical slideways 13 are symmetrically arranged on the inner side of the bottom gate body 1 , and both sides of the gate body door 32 are inserted into the vertical slideways 13 , and the gate body door 32 slides inside the vertical slideways 13 .

[0048] The bottom-sealed silt barrier and removal unit of the hydraulic gate is arranged in the installation cavity 14 area, and is used to seal and remove the silt impurities in the closed area of ​​the gate before the gate is lowered and sealed, so as to ensure the effective closed state of the gate;

[0049] The closed sediment barrier and removal unit at the bottom of the hydraulic gate includes a flushing part, which includes a partition cover 5. A hydraulic lifting rod 41 is installed on the surface of the mounting frame 4. The partition cover 5 is installed at the bottom of the moving end of the hydraulic lifting rod 41. Water inlet holes 55 are arranged on the surface of the partition cover 5. The water inlet holes 55 are arranged in several groups at intervals. A sediment filter plate 51 is obliquely installed on one side of the partition cover 5. A buffer block 52 is also arranged on the surface of the partition cover 5.

[0050] The closed sediment barrier and removal unit at the bottom of the hydraulic gate includes a barrier part, which includes an L-shaped arm 6. A mounting seat 53 is installed on the top of the partition cover 5. The mounting seat 53 is arranged in two groups. An electric drive rotating rod 54 is installed between adjacent mounting seats 53. One end of the L-shaped arm 6 is sleeved on the rotating end of the electric drive rotating rod 54. A lateral pressure plate 61 is installed at one end of the L-shaped arm 6, and a barrier column 62 is installed at the bottom of the lateral pressure plate 61.

[0051] In this embodiment, the hydraulic lifting rod 41 on the surface of the driving mounting frame 4 is moved, and the hydraulic lifting rod 41 moves to push the partition cover 5 to insert into the bottom of the water channel 11 in the gate body. Since the bottom of the water channel 11 in the gate body is a slope, when one side of the water channel 11 in the gate body is blocked, the water flow inside the water channel 11 in the gate body on the other side will flow away quickly, and then the electric drive rotating rod 54 can be driven to rotate. The electric drive rotating rod 54 rotates to drive the L-shaped arm 6 and the lateral pressure plate 61 to rotate and flip up. When the lateral pressure plate 61 flips up and leaves the water inlet hole 55, the upper water flow on one side of the water channel 11 in the gate body connected to the water inlet hole 55 area will be injected from the other side of the partition cover 5 through the water inlet hole 55, and the sediment filter plate 51 will block the sand and gravel in the water flow.

[0052] The hydraulic gate bottom sealing membrane sealing water blocking unit is arranged in the bottom area of ​​the installation cavity 14, and is used to block and seal the water body at the bottom of the gate when the gate is closed.

[0053] The bottom closed membrane sealing water-blocking unit of the hydraulic gate includes a sealing part, which includes a bottom plug-in block 15. The bottom plug-in blocks 15 are arranged in a plurality of groups at intervals. The plurality of groups of bottom plug-in blocks 15 are installed at intervals on the inner wall of the installation cavity 14. Bottom slots 151 are arranged between the bottom plug-in blocks 15. A gate body door 32 is arranged inside the gate frame 3. A top plug-in block 321 is arranged at the bottom of the gate body door 32. The top plug-in block 321 is movably inserted into the bottom slot 151.

[0054] The closed membrane sealing and water-blocking unit at the bottom of the hydraulic gate also includes an air membrane part, which includes a bottom air bin 2, which is installed at the bottom of the bottom gate body 1, and an electromagnetic valve 22 is arranged at the top of the bottom air bin 2 near the installation cavity 14. A flexible diaphragm 12 is sealed and installed at the top of the installation cavity 14. An air chamber 21 is arranged inside the bottom air bin 2, and the air chamber 21 is connected to the installation cavity 14 through the electromagnetic valve 22.

[0055] In this embodiment, the moving block 35 drives the gate door 32 to descend through the moving rod 37. The top insertion block 321 at the bottom of the gate door 32 will slowly insert into the surface of the flexible diaphragm 12 during the descent process. The top insertion block 321 pushes the flexible diaphragm 12 to fit into the bottom slot 151 between the bottom insertion blocks 15 during the continuous insertion process. Then, the top insertion block 321, the flexible diaphragm 12 and the bottom insertion block 15 are tightly fitted, thereby further improving the snap-fit ​​sealing effect at the bottom of the gate door 32.

[0056] Embodiment 2:

[0057] Based on Example 1, this embodiment takes into account that when the water flow of the external water conservancy channel enters one side of the partition cover 5 through the water inlet hole 55, if the flow rate of the water flow is slow, it will affect the flushing effect of the water flow on the sediment accumulated in the flexible diaphragm 12 area. Therefore, a sediment flushing water flow vortex speed increaser unit is provided in this embodiment to guide and increase the speed of the water flow, thereby improving the sediment flushing effect.

[0058] A sediment flushing water flow vortex speed increasing unit is arranged on the side of the partition cover 5 away from the sediment filter plate 51 .

[0059] The sediment flushing water flow vortex speed increasing unit comprises lateral plates 7 , which are symmetrically installed in two groups. The two groups of lateral plates 7 are installed on the side of the partition cover 5 away from the sediment filter plate 51 , and an electrically driven thrust impeller 71 is installed between adjacent lateral plates 7 .

[0060] In this embodiment, the upper water flow on one side of the water channel 11 in the gate body connected to the water inlet hole 55 area will be injected from the other side of the partition cover 5 through the water inlet hole 55, and the sediment filter plate 51 will block the sand and gravel in the water flow, and then drive the electric drive impeller 71 on the side plate 7 to rotate. When the electric drive impeller 71 contacts the water flow entering from the water inlet hole 55, it will rotate and accelerate the water flow, so that the water flow quickly impacts the silt accumulated in the surface area of ​​the flexible diaphragm 12. When the sediment on the surface of the flexible diaphragm 12 is washed away, the bottom buckle sealing effect of the gate door 32 can be effectively guaranteed.

[0061] A method, based on the above-mentioned high-sealing hydraulic gate, comprises the following steps:

[0062] S1: When in use, the engineering personnel first build the bottom gate body 1 into the water conservancy canal. The water flow inside the water conservancy canal will enter the bottom gate body 1 through the water channel 11 in the gate body. After the water continues to flow through the water channel 11 in the gate body, silt will be deposited in the water channel 11 in the gate body. When it is necessary to open, close and seal the water channel 11 in the bottom gate body 1, it is necessary to discharge the silt in the locking area of ​​the gate door 32 at the bottom of the gate frame 3;

[0063] S2: The electric-driven impeller 71 on the overdriven lateral plate 7 is rotated. When the electric-driven impeller 71 contacts the water flow entering from the water inlet hole 55, it will rotate and accelerate the water flow, so that the water flow quickly impacts the silt accumulated on the surface area of ​​the flexible diaphragm 12. When the silt on the surface of the flexible diaphragm 12 is washed away, the bottom buckle sealing effect of the gate 32 can be effectively guaranteed;

[0064] S3: The top insert block 321 at the bottom of the gate body door 32 will slowly insert into the surface of the flexible diaphragm 12 during the descending process. The top insert block 321 pushes the flexible diaphragm 12 to fit into the bottom slot 151 between the bottom insert blocks 15 during the continuous insertion process. Then, the top insert block 321, the flexible diaphragm 12 and the bottom insert block 15 fit tightly together, thereby further improving the buckling and sealing effect of the bottom of the gate body door 32;

[0065] S4: The gas in the air chamber 21 can be injected into the installation cavity 14 through the electromagnetic air valve 22 to increase the air pressure inside the installation cavity 14. The increased air pressure inside the installation cavity 14 pushes the flexible diaphragm 12 to fit tightly to the bottom of the top insert block 321, further improving the sealing performance of the bottom of the gate body door 32.

[0066] Working principle: During the use of the device, when the water channel 11 in the gate body flows normally, the electromagnetic air valve 22 injects the gas in the air chamber 21 into the installation cavity 14. The increase in the air pressure in the installation cavity 14 will fully inflate the flexible diaphragm 12, causing the flexible diaphragm 12 to partially expand and form an arc-shaped bulge. When the water body continues to flow through the arc-shaped bulge of the flexible diaphragm 12, the silt is blocked on one side of the flexible diaphragm 12, thereby preventing a large amount of silt from accumulating on the surface of the flexible diaphragm 12 and reducing the amount of silt accumulation at the bottom of the gate;

[0067] By driving the hydraulic lifting rod 41 on the surface of the mounting frame 4 to move, the hydraulic lifting rod 41 moves to push the partition cover 5 to insert into the bottom of the water channel 11 in the gate body. Since the bottom of the water channel 11 in the gate body is set as a slope, when one side of the water channel 11 in the gate body is blocked, the water flow inside the water channel 11 in the gate body on the other side will flow away quickly, and then the electric drive rotating rod 54 can be driven to rotate, and the rotation of the electric drive rotating rod 54 drives the L-shaped arm 6 and the side pressure plate 61 to rotate and flip up. When the side pressure plate 61 flips up and leaves the water inlet hole 55, the gate connected to the water inlet hole 55 area is blocked. The upper water flow on one side of the internal water channel 11 will be injected from the other side of the partition cover 5 through the water inlet hole 55, and the sediment filter plate 51 will block the sand and gravel in the water flow, and then the electric drive impeller 71 on the side plate 7 will be driven to rotate. When the electric drive impeller 71 contacts the water flow entering from the water inlet hole 55, it will rotate and accelerate the water flow, so that the water flow quickly impacts the silt accumulated on the surface area of ​​the flexible diaphragm 12. When the sediment on the surface of the flexible diaphragm 12 is washed away, the bottom buckle sealing effect of the gate body door 32 can be effectively guaranteed;

[0068] After the mud and sand on the surface of the flexible diaphragm 12 are washed away, the flexible diaphragm 12 area is blocked and sealed to strengthen the on-off blocking effect of the water flow in the waterway 11 in the gate body. At this time, the reduction motor 34 can be driven to rotate, and the rotation of the reduction motor 34 drives the screw 33 to rotate. The rotation of the screw 33 will drive the moving block 35 installed on the surface of the screw 33 to descend vertically along the surface of the limit rod 36. The moving block 35 drives the gate door 32 to descend through the moving rod 37. The top plug-in block 321 at the bottom of the gate door 32 will slowly insert into the surface of the flexible diaphragm 12 during the descent process. The top plug-in block 321 pushes the flexible diaphragm 12 to fit into the bottom slot 151 between the bottom plug-in blocks 15 during the continuous insertion process. Then the top plug-in block 321, the flexible diaphragm 12 and the bottom plug-in block 15 are tightly fitted, thereby further improving the buckling and sealing effect at the bottom of the gate door 32.

[0069] When the bottom of the gate door 32 is buckled and sealed, the electric drive rotating rod 54 can be driven to rotate. The rotation of the electric drive rotating rod 54 drives the L-shaped arm 6 and the lateral pressure plate 61 to rotate and flip up and re-lock on the surface of the water inlet hole 55. The blocking column 62 on the surface of the lateral pressure plate 61 will be blocked on the surface of the corresponding water inlet hole 55, and then the hydraulic lifting rod 41 on the surface of the mounting frame 4 is driven to drive the partition cover 5 to partially rise and reset. After the partition cover 5 is reset, the water flow blocked by the partition cover 5 will quickly flow to the surface of the gate body door 32. In order to further improve the fitting effect between the flexible diaphragm 12 at the bottom of the gate body door 32 and the top plug block 321, the gas in the air chamber 21 can be injected into the installation cavity 14 through the electromagnetic air valve 22 at this time, so as to increase the air pressure inside the installation cavity 14. The increased air pressure inside the installation cavity 14 pushes the flexible diaphragm 12 to fit tightly to the bottom of the top plug block 321, thereby further improving the sealing of the bottom of the gate body door 32.

10. A method, based on the high sealing hydraulic gate according to claim 9, characterized in that: The steps include: S1: When in use, the engineering personnel first build the bottom gate body (1) into the water conservancy canal. The water flow in the water conservancy canal will enter the bottom gate body (1) through the inner water channel (11) of the gate body. After the water continues to flow through the inner water channel (11), silt will be deposited in the inner water channel (11). When it is necessary to open, close and seal the inner water channel (11) of the bottom gate body (1), it is necessary to discharge the silt in the locking area of ​​the gate door (32) at the bottom of the gate frame (3); S2: The electric-driven propeller (71) on the overdriven lateral plate (7) is rotated. When the electric-driven propeller (71) contacts the water flow entering from the water inlet hole (55), the water flow is rotated and accelerated to push the water flow, so that the water flow quickly impacts the silt accumulated on the surface area of ​​the flexible diaphragm (12). When the silt on the surface of the flexible diaphragm (12) is completely washed away, the bottom buckling sealing effect of the gate body (32) can be effectively guaranteed; S3: The top insert block (321) at the bottom of the gate body door (32) is slowly inserted into the surface of the flexible diaphragm (12) during the descending process. The top insert block (321) pushes the flexible diaphragm (12) to fit into the bottom slot (151) between the bottom insert blocks (15) during the continuous insertion process. Subsequently, the top insert block (321), the flexible diaphragm (12) and the bottom insert block (15) fit tightly together, thereby further improving the buckling and sealing effect of the bottom of the gate body door (32); S4: The gas in the air chamber (21) can be injected into the interior of the installation chamber (14) through the electromagnetic air valve (22), thereby increasing the air pressure inside the installation chamber (14). The increased air pressure inside the installation chamber (14) pushes the flexible diaphragm (12) to fit tightly against the bottom of the top insert block (321), further improving the sealing performance of the bottom of the gate body door (32).
