[0015] The present invention has the following beneficial effects:

[0016] 1. In the flood discharge device for the water conservancy project, when the gate is opened, the roller can extend from the storage groove, walk on the first toothed plate through the gear, causing the gear to rotate and the torsion spring to store energy. When the gate is closed, the gear is pulled by the transverse moving block to move from the first toothed plate to the second toothed plate, and the gear meshes with the second toothed plate. When the gear walks on the second toothed plate, the torsion spring continues to store energy until the gear disengages from the second toothed plate. At this time, the roller moves into the sealing groove, the torsion spring releases its force, drives the rotating shaft to rotate, the rotating shaft drives the roller to rotate, and the roller drives the cleaning brush to rotate to clean the sealing groove. After the cleaning is completed, the roller and the cleaning brush are retracted into the storage groove, and the gate seals with the sealing groove, thus facilitating the cleaning of the impurity objects inside the sealing groove before the gate is closed.

[0017] 2. In the flood discharge device for the water conservancy project, when the roller and the cleaning brush are retracted into the storage groove, the roller drives the core rod to move, the core rod drives the longitudinal rod to move, and the longitudinal rod drives the first sliding rod to slide inside the first sliding track, so that the first sliding rod can push the core rod to move. The core rod drives the moving block to slide inside the moving groove, and the moving block drives the mounting plate to move through the transmission rod. The mounting plate drives the cleaning brush to move, and the cleaning brush is retracted into the second telescopic groove. Thus, before the gate is inserted into the sealing groove, the exposed cleaning brush is retracted into the second telescopic groove, so as to avoid squeezing the cleaning brush when the gate moves downward to seal with the sealing groove.

[0018] 3. In the flood discharge device for the water conservancy project, when the gate moves upward, it drives the limit sliding plate to slide inside the limit sliding groove. The limit sliding plate drives the second sliding rod to slide inside the second sliding track. The second sliding rod drives the positioning plate to move through the ejecting component, and the positioning plate drives the sealing strip to move, and the sealing strip is received into the third telescopic groove, so that the sealing strip no longer contacts the inner wall of the limit sliding groove. When the gate seals with the sealing groove, the sealing strip is ejected from the third telescopic groove through the ejecting component again, so that the sealing strip seals the limit sliding plate and the limit sliding groove again. Thus, when the gate moves, the wear of the sealing strip is reduced, and the service life of the sealing strip is increased. In addition, when the sealing strip is received into the third telescopic groove, a channel for water flow is formed between the limit sliding plate and the limit sliding groove, so that the water flow can not only flow under the gate, but also flow through the side plate of the gate, thereby reducing the impact force of the water flow from the front of the gate, which is beneficial to reducing the situation that the gate is bent, and further increasing the protection of the gate.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0036] Embodiment 1. Please refer to Figures 1 - 15 , a flood discharge device for a water conservancy project, including a flood discharge base 1 and a gantry 2. A gate 3 is slidably arranged on the gantry 2. A sealing groove 4 is opened on the upper surface of the flood discharge base 1. A roller 5 is rotatably arranged at the bottom of the gate 3. A cleaning brush 6 is arranged on the roller 5. A rotating shaft 7 is fixed at the end of the roller 5. The end of the rotating shaft 7 is drivingly connected to a gear 8. A first toothed plate 9 and a second toothed plate 10 for meshing with the gear 8 are arranged inside the gantry 2. A rotating rod 11 is rotatably arranged on the outer surface of the gear 8. A first sliding protrusion 13 is fixed on the surface of the rotating rod 11. A first track groove 15 for the first sliding protrusion 13 to slide is opened inside the gantry 2;

[0037] A positioning frame 17 is sleeved on the circumference of the rotating shaft 7. A receiving groove 18 for the roller 5 to rotate is opened at the bottom of the gate 3. A lifting groove 19 is opened inside the gate 3. A lifting block 20 is slidably arranged in the lifting groove 19. A lifting rod 21 is fixed at the bottom of the lifting block 20. The end of the lifting rod 21 is fixed to the upper surface of the positioning frame 17. And a first spring 24 is fixed between the top of the lifting block 20 and the lifting groove 19;

[0038] A torsion spring 26 is sleeved on the circumference of the rotating shaft 7. A square rod 27 is fixed on the surface of the gear 8. The other end of the square rod 27 is slidably inserted into the rotating shaft 7. A telescopic rod 28 is fixed at the end of the rotating rod 11. A cross-moving block 12 is fixed at the end of the telescopic rod 28. A second spring 29 is sleeved outside the telescopic rod 28. A second sliding protrusion 14 is fixed on the surface of the cross-moving block 12. A second track groove 16 for the second sliding protrusion 14 to slide is opened inside the gantry 2. And a second toothed plate 10 for meshing with the gear 8 is arranged inside the gantry 2;

[0039] The first track groove 15 includes a rising part 151, a first translation part 152, a descending part 153 and a second translation part 154 which are connected in sequence. The second track groove 16 includes a first sliding part 161, an inclined part 162 and a second sliding part 163 which are connected in sequence.

[0040] In this technical solution, a servo motor 22 is fixed at the top of the gantry 2, and a threaded rod 23 is rotatably arranged at the top of the gate 3. The end of the threaded rod 23 is drivingly connected to the servo motor 22. When flood discharge is required, the servo motor 22 drives the threaded rod 23 to rotate, and the threaded rod 23 drives the gate 3 to slide on the gantry 2 to open the gate 3 for flood discharge.

[0041] When the gate 3 slides upward, first, the first spring 24 is in a compressed state, and the bottom of the gate 3 slides out of the sealing groove 4. The first spring 24 releases force, causing the lifting rod 21 to drive the lifting block 20 to slide downward in the lifting groove 19. At this time, the gate 3 moves upward, and the positions of the roller 5 and the positioning frame 17 relative to the sealing groove 4 remain unchanged, causing the roller 5 to extend out of the receiving groove 18 at the bottom of the gate 3. When the gate 3 continues to move upward and the lifting block 20 moves to the bottom of the lifting groove 19, the gate 3 will drive the roller 5 to move upward together. When the roller 5 moves upward, the roller 5 drives the rotating shaft 7 to move upward, and the rotating shaft 7 drives the gear 8 to move upward. Initially, the gear 8 is not engaged with the first toothed plate 9. When the gear 8 moves upward, the gear 8 engages with the first toothed plate 9. When the gear 8 moves upward, due to the meshing action between the gear 8 and the first toothed plate 9, the gear 8 rotates, and the rotation of the gear 8 drives the rotating shaft 7 to rotate. Through the arranged torsion spring 26, as Figure 9 shown, one end of the torsion spring 26 is fixedly connected to the surface of the positioning frame 17, and the other end of the torsion spring 26 is fixedly connected to the circumferential surface of the rotating shaft 7. When the rotating shaft 7 moves upward and rotates, the torsion spring 26 is in a state of storing energy.

[0042] When the gear 8 moves upward, it drives the rotating rod 11 to move upward, and the rotating rod 11 drives the transverse moving block 12 to move upward. First, the rotating rod 11 moving upward drives the first sliding protrusion 13 to slide in the first track groove 15, and the transverse moving block 12 drives the second sliding protrusion 14 to slide inside the second track groove 16. When the gate 3 moves upward, the first sliding protrusion 13 slides along the ascending part 151, and the second sliding protrusion 14 first slides along the first sliding part 161, and then the second sliding protrusion 14 slides along the inclined part 162. When the second sliding protrusion 14 slides along the inclined part 162, as Figure 10As shown, since the distance between the inclined portion 162 and the rising portion 151 is greater than the distance between the first sliding portion 161 and the rising portion 151, the transverse movement block 12 moves to the right. The rightward movement of the transverse movement block 12 drives the telescopic rod 28 to extend, and the second spring 29 is stretched and stores energy. When the gate 3 rises to the highest position, the first sliding protrusion 13 slides to the top of the rising portion 151, and the second sliding protrusion 14 slides to the top of the second sliding portion 163. At this time, the second spring 29 releases its energy, the telescopic rod 28 shortens, pulling the first sliding protrusion 13 to slide along the first translation portion 152, so that the first sliding protrusion 13 drives the rotating rod 11 to move to the right. The rotating rod 11 drives the gear 8 to move to the right, moves the gear 8 from the first toothed plate 9 to the second toothed plate 10, and remains engaged with the second toothed plate 10. By providing the square rod 27, the square rod 27 is slidably connected to the rotating shaft 7, so that the gear 8 can move left and right and also drive the rotating shaft 7 to rotate;

[0043] When the gate 3 moves downward to close, due to the engagement of the gear 8 with the second toothed plate 10, the rotation direction of the gear 8 is the same when moving upward and downward, so that the torsion spring 26 remains in a state of storing energy. First, when the gate 3 moves downward, it drives the gear 8 to move downward. At this time, the first sliding protrusion 13 slides downward along the descending portion 153, and the second sliding protrusion 14 slides downward along the second sliding portion 163. When the second sliding portion 163 slides along the inclined portion 162, the transverse movement block 12 moves to the left. The leftward movement of the transverse movement block 12 drives the telescopic rod 28 to contract, and the second spring 29 is compressed and stores energy. When the gate 3 moves downward and drives the roller 5 to first move into the sealing groove 4, at this time, the gear 8 is disengaged from the second toothed plate 10, so that the torsion spring 26 releases its energy, the rotating shaft 7 rotates, the rotating shaft 7 drives the roller 5 to rotate, and the roller 5 drives the cleaning brush 6 to rotate, so that the cleaning brush 6 cleans the sealing groove 4;

[0044] At the same time when the gear 8 is disengaged from the second toothed plate 10, the first sliding protrusion 13 slides to the bottom of the descending portion 153, and the second sliding protrusion 14 slides to the bottom of the first sliding portion 161. The second spring 29 releases its energy, and the telescopic rod 28 shortens, prompting the first sliding protrusion 13 to slide to the left along the second translation portion 154, so that the first sliding protrusion 13 and the second sliding protrusion 14 move to the initial state, thereby resetting the position of the gear 8 to the initial state;

[0045] When the roller 5 drives the cleaning brush 6 to clean the sealing groove 4, the gate 3 has not been fully closed yet. When the gate 3 continues to move downward, it will compress the first spring 24, causing the first spring 24 to store energy, so that the lifting block 20 moves upward in the lifting groove 19, driving the roller 5 to move towards the storage groove 18; during the process of the roller 5 moving towards the storage groove 18, first, the torsion spring 26 is unloaded, enabling the cleaning brush 6 to complete the cleaning work on the sealing groove 4, and the cleaning brush 6 stops rotating. Then the gate 3 continues to move downward to seal with the sealing groove 4, and the roller 5 is completely stored in the storage groove 18.

[0046] In this technical solution, the telescopic rod 28 includes an outer rod and an inner rod that are slidably connected to each other. The inner rod can slide inside the outer rod to realize the telescopic function of the telescopic rod 28. Moreover, the first toothed plate 9 and the second toothed plate 10 are arranged oppositely, so that when the gear 8 moves upward and downward on the first toothed plate 9 and the second toothed plate 10, the torsion spring 26 is in a state of storing energy. In addition, when the gear 8 moves from the first toothed plate 9 to the second toothed plate 10, the meshing effect of the gear 8 will not be released, so that the gear 8 will not rotate; in addition, in order to increase the stability of the gate 3 when moving up and down and prevent deviation, a guide rod 63 is fixed on the flood discharge base 1, and a sleeve 62 is fixed on the surface of the gate 3, so that the guide rod 63 passes through the sleeve 62 and is slidably connected to the sleeve 62. A cross bar 64 is fixed between the end of the guide rod 63 and the gantry 2. When the gate 3 slides up and down, it drives the sleeve 62 to slide along the guide rod 63, thereby increasing the sliding stability of the gate 3. As Figure 1 and Figure 11 shown, the guide rod 63 is arranged outside the gate 3 and does not contact the gate 3. The roller 5 can be retracted into the gate 3, and the diameter of the roller 5 is smaller than the width of the gate 3. Therefore, the guide rod 63 will not affect the rotation of the roller 5.

[0047] In the second embodiment, in order to facilitate the cleaning brush 6 to clean the inside of the sealing groove 4 sufficiently, the outer length of the cleaning brush 6 exposed outside is larger than the inner diameter of the sealing groove 4, so that the cleaning brush 6 can clean the inner wall of the sealing groove 4. However, when the gate 3 seals with the sealing groove 4, the gate 3 needs to be inserted into the sealing groove 4. If the outer length of the cleaning brush 6 is too long, when the gate 3 is inserted into the sealing groove 4, the gate 3 will squeeze the cleaning brush 6, resulting in damage to the cleaning brush 6. To solve this problem, this embodiment is an improvement based on the first embodiment. Specifically, please refer to Figures 1 - 15, a second telescopic groove 30 is formed in the roller 5, a mounting plate 31 is slidably arranged in the second telescopic groove 30, a cleaning brush 6 is fixedly arranged on the mounting plate 31, a moving groove 32 is formed in the interior of the roller 5, a moving block 33 is slidably arranged in the moving groove 32, a first sliding groove 34 is formed in the moving block 33, a transmission rod 35 is slidably arranged in the first sliding groove 34, the end of the transmission rod 35 is fixedly connected to the mounting plate 31, a core rod 36 is rotatably arranged on the surface of the moving block 33, a longitudinal rod 37 is fixed to the end of the core rod 36, a first sliding rod 38 is fixed to the surface of the longitudinal rod 37, and a first sliding track 39 for the first sliding rod 38 to slide is formed in the gate 3;

[0048] A third sliding protrusion 41 is fixed to the end of the transmission rod 35, a first abutting groove 42 for the third sliding protrusion 41 to slide is formed in the inner wall of the first sliding groove 34, a fourth sliding protrusion 43 is fixed to the end of the first sliding rod 38, and a third track groove 44 for the fourth sliding protrusion 43 to slide is formed in the interior of the first sliding track 39. The third track groove 44 includes a first straight groove 441, a first inclined groove 442, and a second straight groove 443 that are sequentially connected and arranged.

[0049] In this technical solution, when the roller 5 extends out from the interior of the storage groove 18, that is, when the roller 5 moves downward relative to the gate 3. When the roller 5 moves downward relative to the gate 3, first, the roller 5 drives the core rod 36 to move downward. The core rod 36 passes through the rotating shaft 7 and the positioning frame 17, and the core rod 36 is slidably connected to the positioning frame 17 and the rotating shaft 7. The core rod 36 is rotatably connected to the moving block 33. The core rod 36 moving downward drives the longitudinal rod 37 and the first sliding rod 38 to move downward. The first sliding rod 38 drives the fourth sliding protrusion 43 to move downward, so that the fourth sliding protrusion 43 first moves downward along the first straight groove 441 of the third track groove 44. When the roller 5 moves out more than half from the storage groove 18, at this time, the fourth sliding protrusion 43 slides along the first inclined groove 442. As Figure 6 shown, the fourth sliding protrusion 43 moves to the right. The fourth sliding protrusion 43 drives the longitudinal rod 37 and the core rod 36 to move to the right. The core rod 36 drives the moving block 33 to move to the right in the moving groove 32. When the moving block 33 moves to the right, it causes the transmission rod 35 to drive the fourth sliding protrusion 43 to slide along the first abutting groove 42, so that the transmission rod 35 pushes the mounting plate 31 to slide in the second telescopic groove 30, thereby moving the cleaning brush 6 out of the second telescopic groove 30 until the fourth sliding protrusion 43 slides into the second straight groove 443, and the cleaning brush 6 completely moves out of the second telescopic groove 30. Then, when the roller 5 continues to move out from the interior of the storage groove 18 until it is completely extended, the fourth sliding protrusion 43 slides to the lowest end along the second straight groove 443;

[0050] When the roller 5 moves inside the storage groove 18, that is, when the roller 5 moves upward relative to the gate 3, first, the fourth sliding protrusion 43 moves upward along the second straight groove 443. At this time, the torsion spring 26 is unloaded, so that the roller 5 drives the cleaning brush 6 to clean the sealing groove 4. When the fourth sliding protrusion 43 slides to the connection of the second straight groove 443 and the first inclined groove 442, the unloading of the torsion spring 26 is completed, the cleaning of the sealing groove 4 is completed, and the roller 5 stops rotating. At this time, the height of the roller 5 received in the storage groove 18 is less than half of the diameter of the roller 5. Then, the fourth sliding protrusion 43 slides upward along the first inclined groove 442. The fourth sliding protrusion 43 drives the first sliding rod 38, the longitudinal rod 37 and the core rod 36 to move leftward for reset. The core rod 36 drives the moving block 33 to move leftward for reset. The moving block 33 drives the transmission rod 35 to reset. The transmission rod 35 drives the mounting plate 31 to reset. The mounting plate 31 drives the cleaning brush 6 to be received into the second telescopic groove 30 again. After that, the fourth sliding protrusion 43 moves upward along the first straight groove 441 until the roller 5 is completely received in the storage groove 18. Through the above process, the cleaning brush 6 can be received into the second telescopic groove 30 before the roller 5 is received into the storage groove 18, so as to avoid squeezing the cleaning brush 6 when the gate 3 moves downward to seal the sealing groove 4.

[0051] Embodiment 3. In order to maintain the sealing performance, sealing strips 49 need to be provided between both sides of the gate 3 and the gantry 2, and the sealing is carried out through the sealing strips 49. However, when the gate 3 moves up and down relative to the gantry 2, the gate 3 and the gantry 2 will cause wear to the sealing strips 49, thereby reducing the service life of the sealing strips 49 and further reducing the sealing effect. To solve this problem, this embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1 - 15 , limit sliding plates 45 are fixed on both sides of the gate 3, limit sliding grooves 46 for the limit sliding plates 45 to slide are formed on the gantry 2, a third telescopic groove 47 is formed in the limit sliding plate 45, a positioning plate 48 is slidably arranged in the third telescopic groove 47, a sealing strip 49 is fixed on the positioning plate 48, a second sliding rod 50 is slidably connected to the limit sliding plate 45, a second sliding track 51 for the second sliding rod 50 to slide is formed on the gantry 2, and an ejecting assembly for the sealing strip 49 to slide is arranged between the second sliding rod 50 and the positioning plate 48;

[0052] A fifth sliding protrusion 52 is fixed at the end of the second sliding rod 50, and a fourth track groove 53 for the fifth sliding protrusion 52 to slide is formed on the inner wall of the second sliding track 51. The fourth track groove 53 includes a second inclined groove 531 and a third straight groove 532 which are connected in sequence;

[0053] The ejection assembly includes an adjustment block 54 slidably set inside the limiting slide plate 45, the end of the second slide rod 50 is fixed to the adjustment block 54, a second slide groove 55 is provided on the adjustment block 54, an ejection rod 56 is slidably set in the second slide groove 55, the end of the ejection rod 56 is fixed to the positioning plate 48, a second interference groove 57 is provided on the inner wall of the second slide groove 55, a sixth sliding protrusion 58 is fixed to the end of the ejection rod 56, and the sixth sliding protrusion 58 is slidably set in the second interference groove 57.

[0054] In the present technical solution, when the gate 3 just moves upward, the gate 3 drives the limiting slide 45 to move upward, the limiting slide 45 drives the second slide bar 50 to slide upward in the second slideway 51, and the second slide bar 50 drives the fifth sliding protrusion 52 to slide inside the second inclined groove 531 of the fourth track groove 53, as shown in FIG. Figure 14 As shown, the fifth sliding protrusion 52 drives the second sliding rod 50 to move leftward. When the second sliding rod 50 moves leftward, as shown in FIG. Figure 12 As shown, the second slide bar 50 drives the adjustment block 54 to move leftward, so that the ejector rod 56 drives the sixth sliding protrusion 58 to slide inside the second abutting groove 57, so that the ejector rod 56 drives the positioning plate 48 to slide in the third telescopic groove 47, and the sealing strip 49 is received into the third telescopic groove 47, thereby separating the sealing strip 49 from the surface of the limiting slide groove 46, and then the gate 3 continues to slide upward, and the fifth sliding protrusion 52 moves upward along the third straight groove 532, and the position of the sealing strip 49 remains unchanged, so that the sealing strip 49 does not contact the inner wall of the limiting slide groove 46 when the gate 3 moves upward, thereby reducing the wear of the sealing strip 49, which is conducive to increasing the service life of the sealing strip 49;

[0055] When the gate 3 moves downward, the fifth sliding protrusion 52 first slides inside the third straight groove 532, and the sealing strip 49 does not contact the inner wall of the limiting slide groove 46, and no wear occurs. When the fifth sliding protrusion 52 slides along the second inclined groove 531, the fifth sliding protrusion 52 drives the second slide bar 50 to reset to the right, and the second slide bar 50 drives the adjusting block 54 to reset to the right, and the adjusting block 54 drives the ejection rod 56 and the positioning plate 48 to reset, so that the sealing strip 49 extends out from the third telescopic groove 47 again until the gate 3 moves downward to the bottom position and seals with the sealing groove 4. The sealing strip 49 is reset, so that the sealing strip 49 again conflicts with the inner wall of the limiting slide groove 46, completing the seal between the limiting slide groove 46 and the limiting slide plate 45.

[0056] Embodiment 4: This embodiment is another technical solution for the ejection assembly. For details, please refer to Figures 1 - 15, the ejecting assembly includes a contact block 59 slidably disposed inside the limit slide plate 45. The end of the second slide rod 50 is fixed to the contact block 59. A contact rod 60 is slidably disposed on the contact block 59. The end of the contact rod 60 is fixed to the positioning plate 48. A third spring 61 is fixed between the positioning plate 48 and the third telescopic groove 47.

[0057] In this technical solution, as Figure 15 shown, the contact surfaces of the contact block 59 and the contact rod 60 are both arranged as inclined surface structures. The third spring 61 is in a stretched state. When the second slide rod 50 moves to the left, the second slide rod 50 drives the contact block 59 to move to the left. The contact rod 60 loses the contact of the contact block 59, and the third spring 61 unloads force, so that the contact rod 60 slides along the surface of the contact block 59. At the same time, the contact rod 60 drives the positioning plate 48 to slide inside the third telescopic groove 47. The positioning plate 48 houses the sealing strip 49 into the third telescopic groove 47, so that when the gate 3 moves upward, the sealing strip 49 does not contact the inner wall of the limit sliding groove 46, thereby reducing the wear of the sealing strip 49;

[0058] When the second slide rod 50 moves to the right to reset, the second slide rod 50 drives the contact block 59 to move to the right. The contact block 59 contacts the contact rod 60, prompting the contact rod 60 to drive the positioning plate 48 to move and stretch the third spring 61, so that the third spring 61 stores energy. The positioning plate 48 drives the sealing strip 49 to extend from the third telescopic groove 47, so that the sealing strip 49 seals between the limit slide plate 45 and the limit sliding groove 46 again.
