A water control gate for cleaning sediment deposits

Abstract

The present invention relates to the field of water control gates, and particularly to a water control gate for cleaning sediment. Existing water control gates will be eroded and worn by sediment particles, resulting in poor sealing effect of the water control gates, and it is difficult to clean the sediment adhering to the bottom of the ditch, resulting in poor sediment cleaning effect. A water control gate for cleaning sediment includes: a fixed frame with a sealing groove, a cover plate fixedly connected to the fixed frame, and a water retaining plate slidably connected in the sealing groove of the fixed frame. When the water retaining plate and the threaded rod move upward, they will drive the sliding frame to move upward. When the water retaining plate moves a certain distance to expose the diversion opening of the diversion ring, the water flow at the bottom of the ditch will drive the deposited sediment to flow when it reaches the other side of the water retaining plate, so that the flowing sediment passes through the diversion holes of the diversion ring. The diversion ring can protect the sealing groove of the fixed frame and the bottom of the water retaining plate, thereby enhancing the sealing effect between the fixed frame and the water retaining plate.

Description

Technical Field

[0001] The present invention relates to the field of water conservancy gates, and particularly to a water conservancy gate for cleaning sediment deposits. Background Art

[0002] In water conservancy projects, water conservancy gates, as structures for blocking water, discharging water or taking water, are widely used. Closing the gate can intercept floods or raise the upstream water level to meet the needs of irrigation, power generation, industrial and domestic water use, etc.; opening the gate can discharge floods, waste water or wastewater, and can also supply water to the downstream river or channel.

[0003] Sediment will accumulate on the side of the water conservancy gate near the upstream. During the long-term process of intercepting water flow and controlling the water level, sediment will deposit near the water conservancy gate. Generally, the water conservancy gate is opened, and the water flow rushes out at high speed from the bottom of the water conservancy gate, and the sediment particles carried by the water flow will flow away. However, the sediment particles carried by the water flow will cause continuous scouring and wear on the bottom plate, threshold and metal surface of the gate slot of the gate, resulting in poor sealing effect of the water conservancy gate. Moreover, some deposited sediment will closely adhere to the bottom of the ditch, and it is difficult to take it away by the impact of the water flow, resulting in poor sediment cleaning effect. Summary of the Invention

[0004] In order to overcome the shortcomings that the existing water conservancy gates will be scoured and worn by sediment particles, resulting in poor sealing effect of the water conservancy gates, and it is difficult to clean the sediment adhering to the bottom of the ditch, resulting in poor sediment cleaning effect, the present invention provides a water conservancy gate for cleaning sediment deposits that can protect the fixed frame and the water retaining plate, enhance the sealing effect of the water conservancy gate, and can clean the sediment more thoroughly.

[0005] The technical solution is: a water conservancy gate for cleaning sediment deposits, comprising:

[0006] A fixed frame with a sealing groove;

[0007] A cover plate fixedly connected to the fixed frame;

[0008] A water retaining plate slidably connected in the sealing groove of the fixed frame;

[0009] A lifting mechanism provided on the fixed frame;

[0010] A limiting mechanism provided on the fixed frame;

[0011] A protection mechanism provided on the limiting mechanism.

[0012] Further, the lifting mechanism includes: a driving motor fixedly connected to the fixed frame, a threaded sleeve rotatably connected to the fixed frame, a driven gear fixedly connected to the threaded sleeve, a driving gear fixedly connected to the output shaft of the driving motor, the driving gear meshing with the driven gear, a housing fixedly connected to the fixed frame, a threaded rod fixedly connected to the water baffle, and the threaded rod is threadedly connected to the threaded sleeve.

[0013] Further, the limiting mechanism includes: four guiding blocks fixedly connected to the fixed frame, with two guiding blocks as a group, two limiting blocks respectively slidably connected to the two groups of guiding blocks and having limiting grooves, four reset springs respectively connecting the two limiting blocks with the four guiding blocks, two guiding plates respectively fixedly connected to the two limiting blocks, a sliding frame slidably connected to the fixed frame, the sliding frame being fixedly connected to the water baffle, and the sliding frame contacting the guiding plates.

[0014] Further, each guiding plate has two inclined surfaces.

[0015] Further, the protection mechanism includes: a diversion ring slidably connected to the sealing groove of the fixed frame and having a diversion port, the diversion ring being slidably connected to the water baffle, two lifting rods fixedly connected to the diversion ring, the two lifting rods being slidably connected to the fixed frame, the two lifting rods contacting the limiting grooves of the two limiting blocks, and two contact rods fixedly connected to the two lifting rods.

[0016] Further, there is also a stirring mechanism for stirring the deposited sediment, provided in the fixed frame. The stirring mechanism includes: two driven frames slidably connected to the fixed frame, the two driven frames being fixedly connected to the sliding frame, a sliding frame slidably connected within the fixed frame and having two guiding grooves, the two driven frames being slidably connected to the two guiding grooves of the sliding frame, a rack frame fixedly connected to the sliding frame, a plurality of stirring frames rotatably connected to the cover plate, a plurality of rotating gears fixedly connected to the plurality of stirring frames, and the plurality of rotating gears meshing with the rack frame.

[0017] Further, there is also a spraying mechanism for cleaning the water baffle, provided within the fixed frame. Two sealing cylinders fixedly connected to the fixed frame and having two communication holes, a spraying pipe fixedly connected to the cover plate, the spraying pipe being fixedly connected and communicating with one of the two communication holes of the two sealing cylinders, two sliding plates respectively slidably connected within the two sealing cylinders, the two sliding plates being fixedly connected to the two sliding frames, and four one-way valves respectively fixedly connected within the four communication holes of the two sealing cylinders.

[0018] Further, there is also a scraping plate, a scraping plate fixedly connected to the diversion ring, and the scraping plate contacts the water baffle.

[0019] Compared with the prior art, the present invention has the following advantages: 1. When the threaded rod moves upward, it drives the water baffle to move upward. As the water baffle and the threaded rod move upward, they will drive the sliding frame to move upward. When the water baffle moves a certain distance, the diversion opening of the diversion ring is exposed. The water at the bottom of the ditch flows from the diversion holes of the diversion ring to the other side of the water baffle. When the water at the bottom of the ditch flows to the other side of the water baffle, it will drive the deposited sediment to flow, so that the flowing sediment passes through the diversion holes of the diversion ring. The diversion ring can protect the sealing groove of the fixed frame and the bottom of the water baffle, thereby enhancing the sealing effect between the fixed frame and the water baffle.

[0020] 2. When the sliding frame moves upward, it will drive the driven frame to move upward. When the driven frame moves upward, it will squeeze the guiding groove of the sliding frame, causing the sliding frame to move reciprocally. The reciprocating movement of the sliding frame will drive the rack frame to reciprocate. The reciprocating movement of the rack frame will drive the rotating gear to rotate reciprocally. The reciprocating rotation of the rotating gear will drive the stirring frame to rotate reciprocally. The reciprocating rotation of the stirring frame will stir the sediment deposited at the bottom of the ditch, preventing the deposited sediment from adhering tightly to the bottom of the ditch. Thus, the deposited sediment can be discharged through the diversion opening of the diversion ring, significantly enhancing the cleaning effect on the sediment.

[0021] 3. The sliding plate will squeeze the water in the sealing cylinder, causing the water in the sealing cylinder to be discharged into the spray pipe through the one-way valve above. Then the water sprays out from the spray pipe. At the same time, the water baffle is moving upward. The water sprayed out from the spray pipe will clean the water baffle. When the sluice is opened to release water, the water sprayed out from the spray pipe will clean the entire water baffle, thereby cleaning the deposited sediment adhering to the side of the water baffle more thoroughly, and further enhancing the cleaning effect on the sediment.

Detailed implementation manners

Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0036] Embodiment 1: A water gate for cleaning sediment deposits, as Figures 1 - 5 shown, includes:

[0037] A fixed frame 1 with a sealing groove;

[0038] A cover plate 2 connected to the fixed frame 1 by bolts;

[0039] A water baffle 3 slidably connected in the sealing groove of the fixed frame 1, and a sealing strip is provided on the water baffle 3;

[0040] Lifting mechanism, used to lift the water baffle 3, is arranged on the fixed frame 1;

[0041] Restriction mechanism, used to restrict the movement of parts, is arranged on the fixed frame 1;

[0042] Protection mechanism, used to protect the sealing groove of the fixed frame 1, is arranged on the restriction mechanism.

[0043] The lifting mechanism includes: a driving motor 41 bolted to the fixed frame 1, a threaded sleeve 42 rotatably connected to the fixed frame 1, a driven gear 43 welded to the threaded sleeve 42, a driving gear 44 fixed to the output shaft of the driving motor 41, the driving gear 44 meshing with the driven gear 43, a housing 45 bolted to the fixed frame 1, a threaded rod 46 welded to the water baffle 3, and the threaded rod 46 is threadedly connected to the threaded sleeve 42.

[0044] The restriction mechanism includes: four guide blocks 51 welded to the fixed frame 1, with two guide blocks 51 in a group, two restriction blocks 52 respectively slidingly connected to the two groups of guide blocks 51 and having restriction grooves, four return springs 522 connected between the two restriction blocks 52 and the four guide blocks 51 respectively, two guide plates 53 welded to the two restriction blocks 52 respectively, a sliding frame 54 slidingly connected to the fixed frame 1, the sliding frame 54 being welded to the water baffle 3, and the sliding frame 54 contacting the guide plates 53.

[0045] Each guide plate 53 has two inclined surfaces.

[0046] The protection mechanism includes: a diversion ring 61 slidingly connected in the sealing groove of the fixed frame 1 and having a diversion port, the diversion ring 61 being slidingly connected to the water baffle 3, two lifting rods 62 welded to the diversion ring 61, the two lifting rods 62 being slidingly connected to the fixed frame 1, the two lifting rods 62 contacting the restriction grooves of the two restriction blocks 52, and the restriction grooves of the restriction blocks 52 being used to restrict the upward movement of the lifting rods 62, and two contact rods 63 welded to the two lifting rods 62.

[0047] At first, the entire gate is installed in the ditch, and the water retaining plate 3 intercepts the water in the ditch. When too much sediment accumulates on one side of the water retaining plate 3, the staff starts the drive motor 41. The output shaft of the drive motor 41 drives the driving gear 44 to rotate. The rotation of the driving gear 44 drives the driven gear 43 to rotate. The rotation of the driven gear 43 drives the threaded sleeve 42 to rotate. The rotation of the threaded sleeve 42 squeezes the threaded rod 46, causing the threaded rod 46 to move upward. The upward movement of the threaded rod 46 drives the water retaining plate 3 to move upward. The upward movement of the water retaining plate 3 and the threaded rod 46 drives the sliding frame 54 to move upward. The upward movement of the sliding frame 54 squeezes the inclined surface of the guide plate 53, causing the guide plate 53 to move. The movement of the guide plate 53 drives the limiting block 52 to move. The movement of the limiting block 52 causes the return spring 522 to be in a compressed state. Since the limiting grooves of the two limiting blocks 52 also limit the lifting rod 62, the lifting rod 62, the diversion ring 61, and the contact rod 63 will not move. The water retaining plate 3 moves a certain distance, causing the diversion port of the diversion ring 61 to be exposed. Then the staff turns off the drive motor 41, and the threaded sleeve 42, the driven gear 43, the driving gear 44, the threaded rod 46, the limiting block 52, the return spring 522, the guide plate 53, and the sliding frame 54 stop moving. The water at the bottom of the ditch flows from the diversion holes of the diversion ring 61 to the other side of the water retaining plate 3. When the water at the bottom of the ditch flows to the other side of the water retaining plate 3, it drives the deposited sediment to flow, causing the flowing sediment to pass through the diversion holes of the diversion ring 61. The diversion ring 61 can protect the sealing groove of the fixed frame 1 and the bottom of the water retaining plate 3, thereby enhancing the sealing effect between the fixed frame 1 and the water retaining plate 3. After a period of time, when the water takes away the deposited sediment, the staff restarts the drive motor 41, causing the output shaft of the drive motor 41 to reverse. The drive motor 41 drives the threaded rod 46 to move downward through the driving gear 44, the driven gear 43, and the threaded sleeve 42. The downward movement of the threaded rod 46 drives the water retaining plate 3 and the sliding frame 54 to move downward. The downward movement of the water retaining plate 3 closes with the diversion ring 61 again. The downward movement of the sliding frame 54 disengages from the guide plate 53. The guide plate 53 and the limiting block 52 are reset under the drive of the return spring 522. After the reset is completed, the staff turns off the drive motor 41;When drainage is required, the staff starts the drive motor 41. The drive motor 41 drives the threaded rod 46 to move upward through the driving gear 44, the driven gear 43 and the threaded sleeve 42. The upward movement of the threaded rod 46 drives the water baffle 3 and the sliding frame 54 to move upward. The upward movement of the sliding frame 54 squeezes the guide plate 53 to move. The movement of the guide plate 53 drives the limiting block 52 to move. The movement of the limiting block 52 compresses the return spring 522. The continuous movement of the limiting block 52 causes the limiting groove of the limiting block 52 to no longer limit the lifting rod 62. The sliding frame 54 continues to move upward and contacts the contact rod 63 and drives the contact rod 63 to move upward. The upward movement of the contact rod 63 drives the diversion ring 61 and the lifting rod 62 to move upward. At the same time, the upward movement of the sliding frame 54 disengages from the guide plate 53. The guide plate 53 and the limiting block 52 are reset under the drive of the return spring 522. Then the sliding frame 54, the contact rod 63, the water baffle 3, the diversion ring 61 and the lifting rod 62 move upward together, so that the water baffle 3 and the diversion ring 61 no longer block the water flow in the ditch. Then the staff turns off the drive motor 41. When the water flow in the ditch is drained to the designated position, the staff restarts the drive motor 41, causing the output shaft of the drive motor 41 to reverse. The drive motor 41 drives the threaded rod 46 to move downward through the driving gear 44, the driven gear 43 and the threaded sleeve 42. The downward movement of the threaded rod 46 drives the water baffle 3 and the sliding frame 54 to move downward. The downward movement of the sliding frame 54 disengages from the contact rod 63. The diversion ring 61, the lifting rod 62 and the contact rod 63 move downward under the action of gravity. The threaded rod 46, the water baffle 3, the sliding frame 54, the diversion ring 61, the lifting rod 62 and the contact rod 63 move downward together. The downward movement of the sliding frame 54 contacts the guide plate 53 and pushes the guide plate 53 to move. The movement of the guide plate 53 drives the limiting block 52 to move. The movement of the limiting block 52 compresses the return spring 522. The threaded rod 46, the water baffle 3, the sliding frame 54, the diversion ring 61, the lifting rod 62 and the contact rod 63 continue to move downward. The lifting rod 62 continues to move downward and contacts the limiting groove of the limiting block 52. At the same time, the diversion ring 61 contacts the bottom of the sealing groove of the fixed frame 1, so that the diversion ring 61, the lifting rod 62 and the contact rod 63 stop moving. The threaded rod 46, the water baffle 3 and the sliding frame 54 continue to move downward. The sliding frame 54 continues to move downward and disengages from the guide plate 53. The guide plate 53 and the limiting block 52 are reset under the drive of the return spring 522. After the threaded rod 46, the water baffle 3 and the sliding frame 54 move downward in place, the water baffle 3 closes with the diversion ring 61. Then the staff turns off the drive motor 41.;

[0048] Embodiment 2: On the basis of Embodiment 1, as Figures 6 - 9As shown in the figure, it further includes a stirring mechanism for stirring the deposited sediment, which is arranged on the fixed frame 1. The stirring mechanism includes: two driven frames 71 slidably connected to the fixed frame 1, the two driven frames 71 are welded to the sliding frame 54, the sliding frame 54 is slidably connected within the fixed frame 1 and is provided with two guiding grooves, the two driven frames 71 are slidably connected to the two guiding grooves of the sliding frame 54, a rack frame 73 welded to the sliding frame 54, several stirring frames 74 rotatably connected to the cover plate 2, the stirring frames 74 are used for stirring the deposited sediment, several rotating gears 75 welded to the several stirring frames 74, and the several rotating gears 75 are meshed with the rack frame 73.

[0049] When the sliding frame 54 moves upward, it will drive the driven frame 71 to move upward. When the driven frame 71 moves upward, it will squeeze the guiding groove of the sliding frame 54, causing the sliding frame 54 to reciprocate. When the sliding frame 54 reciprocates, it will drive the rack frame 73 to reciprocate. When the rack frame 73 reciprocates, it will drive the rotating gear 75 to rotate reciprocally. When the rotating gear 75 rotates reciprocally, it will drive the stirring frame 74 to rotate reciprocally. The reciprocal rotation of the stirring frame 74 will stir the sediment deposited at the bottom of the ditch, preventing the deposited sediment from adhering tightly to the bottom of the ditch. Thus, the deposited sediment can be discharged through the diversion opening of the diversion ring 61, significantly enhancing the cleaning effect of the sediment. When the sliding frame 54 moves downward, it will drive the driven frame 71 to reset downward. When the driven frame 71 resets downward, it will cause the sliding frame 72 to reciprocate. The reciprocal movement of the sliding frame 72 will drive the rack frame 73 to reciprocate, and the reciprocal movement of the rack frame 73 causes the stirring frame 74 and the rotating gear 75 to rotate reciprocally.

[0050] Embodiment 3: On the basis of Embodiment 2, as Figures 6 - 12 shown in the figure, it further includes a spraying mechanism for cleaning the water baffle 3, which is arranged within the fixed frame 1. Two sealing cylinders 81 are connected to the fixed frame 1 by bolts and are provided with two communication holes. A spray pipe 82 is connected to the cover plate 2 by bolts. The spray pipe 82 is fixedly connected and communicated with one of the communication holes of the two sealing cylinders 81. Two sliding plates 83 are respectively slidably connected within the two sealing cylinders 81. The two sliding plates 83 are welded to the two sliding frames 72. Four one-way valves 84 are respectively fixedly connected within the four communication holes of the two sealing cylinders 81.

[0051] Initially, the space between the sealing cylinder 81 and the sliding plate 83 is filled with water. The reciprocating movement of the carriage 72 drives the reciprocating movement of the sliding plate 83. When the sliding plate 83 moves away from the sealing cylinder 81, the sliding plate 83 squeezes the water in the sealing cylinder 81, causing the water in the sealing cylinder 81 to be discharged into the spray pipe 82 through the one-way valve 84 above. Then the water sprays out from the spray pipe 82. At the same time, the water baffle 3 moves upward, and the water sprayed out from the spray pipe 82 cleans the water baffle 3. When the sluice is opened to release water, the water sprayed out from the spray pipe 82 cleans the entire water baffle 3, thereby cleaning the sediment adhering to the side of the water baffle 3 more thoroughly, further enhancing the sediment cleaning effect. When the sliding plate 83 moves towards the sealing cylinder 81, water is drawn into the sealing cylinder 81 through the one-way valve 84 below the sealing cylinder 81, and then the process repeats continuously until the carriage 72 stops moving, causing the sliding plate 83 to stop moving.

[0052] Embodiment 4: On the basis of Embodiment 3, as Figure 3 shown, it further includes a scraping plate 9, which is welded to the diversion ring 61 and contacts the water baffle 3.

[0053] When the water baffle 3 moves upward relative to the diversion ring 61, since the scraping plate 9 is fixedly connected to the diversion ring 61, the scraping plate 9 moves relative to the water baffle 3, and the scraping plate 9 scrapes the side of the water baffle 3, reducing the sediment deposited on the side of the water baffle 3, thereby making the sediment cleaning more thorough. The movement of the diversion ring 61 drives the movement of the water baffle 3.

[0054] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
