[0016] The present invention is provided with components such as a plug-in telescopic rod, a spiral groove, a pressure plate and a buoyancy structure. The water surface pushes the buoyancy structure upward, and then drives the movable plate to move downward by a certain distance. When the visual observation controller observes that the telescopic end of the vertical telescopic rod is active, it controls the double-axis power box to drive the two torsion columns to rotate a certain number of circles. When the pressure plate follows the movable plate to move downward, the lower end inclined surface applies a thrust to the vertical rod, thereby pushing the plug-in telescopic rod to move outside the frame. After the plug-in telescopic rod moves to the outside of the frame, it contacts the torsion column. During the rotation of the torsion column, the telescopic end of the plug-in telescopic rod is inserted into the spiral groove.

When the plug-in telescopic rod moves upward all the time, it detaches from the upper end of the spiral groove. As the pressing depth of the pressure plate increases, the corresponding gate plate is continuously pushed to the upper end of the spiral groove, so that water higher than the lower gate plate can flow to the other side of the gate plate in time, and after the water surface is lowered to below the lower gate plate, the water discharge automatically stops.

[0017] The present invention sets a threaded shaft and a movable block. When the threaded shafts corresponding to the two tooth plates rotate, the threaded shafts respectively change the initial positions of the buoyancy structure and the movable plate by meshing with the corresponding movable blocks. Changing the height of the buoyancy structure can control the highest position and the lowest position of the buoyancy structure, control the number of gate plates that finally remain below the water surface, and further control the final water surface height.

[0018] The present invention provides a water cavity, an inner groove, a sloped rod and a side plate. When the upper gate plate is lowered, when the upper side plate contacts the slope of the lower sloped rod, the sloped rod compresses the compression spring and enters the inner groove, pushing the water flow in the water cavity of the lower gate plate to flow from the fine holes to the groove on the upper surface of the gate plate. The flowing airflow pushes out the impurities in the groove on the upper surface of the gate plate, preventing the impurities in the groove of the gate plate from blocking the insertion of the plug plate. After the plug plate is inserted into the groove of the gate plate, the sealing between the two adjacent gate plates is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] The present application embodiment discloses an intelligent water discharge gate for water conservancy projects. Figure 1 As shown, it includes a gate frame 1, and a plurality of gate plates 6 are slidably inserted inside the gate frame 1.

[0031] The upper surface of the gate plate 6 is groove-shaped, and an insert plate 61 is arranged between each two adjacent gate plates 6. The upper end of the insert plate 61 is fixed to the adjacent gate plates 6. The shape of the insert plate 61 is adapted to the groove-shaped structure of the upper surface of the gate plate 6. When the upper gate plate 6 contacts the lower gate plate 6, the upper insert plate 61 is inserted into the groove of the lower gate plate 6 to improve the sealing between the two adjacent gate plates 6.

[0032] Side plates 62 are provided on both the front and rear sides of the plug plate 61. The upper ends of the side plates 62 are fixed to the bottom surface of the gate plate 6 located above the adjacent gate plate. A water cavity 63 is provided inside the gate plate 6. The water cavity 63 is connected to the groove of the gate plate 6 through a plurality of fine holes 64. Two inner grooves 65 are provided inside the gate plate 6 and below the water cavity 63. Inclined rods 66 are slidably inserted on the front and back sides of the gate plate 6. One end of the inclined rod 66 is located inside the inner groove 65. The upper surface of one end of the inclined rod 66 located outside the gate plate 6 is an inclined surface. The shape of the two side plates 62 connected to the same gate plate 6 is adapted to the shape of the gate plate 6. The interior of the inner groove 65 is connected to the interior of the water cavity 63. The inclined rod 66 is located between the two side plates 62 on both sides of the gate plate 6. A compression spring 67 is fixed to one end of the inclined rod 66 located inside the inner groove 65. The other end of the compression spring 67 is fixed to the inner wall of the inner groove 65. When the upper gate plate 6 moves downward under gravity and drives the side plate 62 to contact and apply pressure to the inclined rod 66 below, the side plate 62 compresses the compression spring 67 through the contact with the inclined surface of the inclined rod 66, pushing the inclined rod 66 into the inner groove 65, so that the water in the inner groove 65 and the water cavity 63 impacts the impurities in the groove of the gate plate 6 from the pores 64, flushes the impurities out of the groove of the gate plate 6, and makes the plug plate 61 move downward to fully cooperate with the groove of the lower gate plate 6.

[0033] A support frame 2 is installed on the front of the gate frame 1, and a reverse transmission structure 7 is rotatably installed in the middle position of the support frame 2. A buoyancy structure 3 is arranged in front of the support frame 2, and the buoyancy structure 3 is located in front of the reverse transmission structure 7. A movable plate 5 is arranged between the gate frame 1 and the reverse transmission structure 7, and a vertical telescopic rod 4 is installed on the upper surface of the movable plate 5. The fixed end of the vertical telescopic rod 4 is fixed to the gate frame 1, and the two ends of the reverse transmission structure 7 are respectively connected to the buoyancy structure 3 and the movable plate 5.

[0034] The reverse transmission structure 7 includes a gear 71 and two tooth plates 72. The gear 71 is rotationally connected to the middle position of the support frame 2. The two tooth plates 72 are meshed with the gear 71. The two tooth plates 72 are arranged in parallel. The two tooth plates 72 are distributed in a circular array around the axis of the gear 71. Double-headed plug blocks 74 are fixed to the middle position of the support frame 2 and on the left and right sides of the gear 71. The two ends of the double-headed plug block 74 are respectively slidably inserted into the sides of the two tooth plates 72 that are close to each other. The outer surfaces of the two tooth plates 72 are slidably sleeved with movable blocks 73. The front side of the movable block 73 located in front of the gear 71 is fixed to the buoyancy structure 3, and the back side of the other movable block 73 is fixed to the movable plate 5.

[0035] The right sides of the two toothed plates 72 are rotatably connected with threaded shafts 75, and the two movable blocks 73 are respectively threadedly sleeved on the outer surfaces of the two threaded shafts 75. Motors 76 are fixed to the upper surfaces of the two toothed plates 72, and the upper ends of the two threaded shafts 75 are respectively fixed to the output ends of the two motors 76. The two motors 76 can drive the two threaded shafts 75 to rotate respectively, and can respectively control the positions of the two movable blocks 73 relative to the toothed plates 72.

[0036] When the buoyancy of the buoyancy structure 3 drives the corresponding tooth plate 72 to move under the buoyancy of the water surface, the tooth plate 72 moving upwards engages with the gear 71 to push the tooth plate 72 on the other side to move downward, so that the movable plate 5 moves downward.

[0037] A square frame 8 is installed on both left and right ends of the front side of the gate plate 6, and a plug-in telescopic rod 9 is arranged inside the square frame 8. A vertical rod 11 is fixed to one end of the plug-in telescopic rod 9 located inside the square frame 8. The vertical rod 11 is elastically connected to the inside of the square frame 8. The vertical rod 11 elastically connected to the frame 8 has a tendency to drive the plug-in telescopic rod 9 to move into the square frame 8, and the vertical rod 11 is slidably plugged into the inside of the frame 8.

[0038] The front side of the gate frame 1 is rotatably connected to two torsion columns 10, and the gate plate 6 is located between the two torsion columns 10. A dual-axis power box 12 is installed at the upper end of the gate frame 1. The upper ends of the two torsion columns 10 are respectively fixed to the two output ends of the dual-axis power box 12. A visual observation controller 13 is installed on the front side of the dual-axis power box 12 and on the left and right sides of the telescopic end of the vertical telescopic rod 4. The visual observation controller 13 is located above the movable plate 5. A spiral groove 15 is provided on the outer surface of the torsion column 10. A brush plate is installed in front of the torsion column 10. Both ends of the brush plate are connected to the gate frame 1. When the torsion column 10 rotates, the brush plate can clean the inside of the spiral groove 15. When the visual observation controller 13 detects that the vertical telescopic rod 4 is extended, the dual-axis power box 12 is controlled to drive the two torsion columns 10 to rotate. The end of the plug-in telescopic rod 9 away from the central axis of the gate frame 1 slides through the inner wall of the frame 8, and the plug-in telescopic rod 9 is located between the two torsion columns 10.

[0039] Two pressing plates 14 are fixedly connected to the bottom surface of the movable plate 5, and the square frames 8 at both ends of the gate plate 6 are respectively located below the two pressing plates 14. The bottom surfaces of the two pressing plates 14 are distributed in a V shape. A wide groove 16 is provided in the middle position of the bottom surface of the pressing plate 14. The cross-section of the pressing plate 14 is smaller than the cross-section of the square frame 8. The length of the front and rear inner walls of the wide groove 16 is greater than the diameter of the fixed end of the plug-in telescopic rod 9. After the pressing plate 14 is inserted into the square frame 8, the inclined surface of the pressing plate 14 gradually pushes the plug-in telescopic rod 9 out of the square frame 8 by pushing the vertical rod 11, which has a tendency to insert the plug-in telescopic rod 9 into the spiral groove 15 of the torsion column 10. When the spiral groove 15 rotates, the plug-in telescopic rod 9 can be pushed to move upward, thereby driving the corresponding gate plate 6 to move upward.

[0040] The implementation principle of one embodiment of the present application is as follows: by controlling two motors 76 respectively to drive two threaded shafts 75 to rotate respectively, the threaded shafts 75 change the initial positions of the buoyancy structure 3 and the movable plate 5 respectively by meshing with the corresponding movable blocks 73, the buoyancy structure 3 floats on the water surface under buoyancy, when the water surface height rises and water needs to be discharged, the water surface pushes the buoyancy structure 3 upward, the buoyancy structure 3 drives the corresponding tooth plate 72 to move upward, the tooth plate 72 moving upward pushes the tooth plate 72 on the other side to move downward by meshing with the gear 71, and drives the vertical telescopic rod 4 to stretch through the movable plate 5, when the visual observation controller 13 observes that the telescopic end of the vertical telescopic rod 4 is moving, the dual-axis power box 12 is controlled to drive the two torsion columns 10 to rotate a certain number of circles, when the pressure plate 14 follows the movable plate 5 to move downward, the lower end inclined surface applies a thrust to the vertical rod 11, and pushes the plug-in telescopic rod 9 to move outside the frame 8, and the plug-in telescopic rod 9 moves to the outside of the frame 8. After the plug-in telescopic rod 9 moves to the outside of the frame 8, it contacts the torsion column 10, and the telescopic end of the plug-in telescopic rod 9 is inserted into the spiral When the torsion column 10 drives the spiral groove 15 to rotate, the plug-in telescopic rod 9 drives the corresponding gate plate 6 to move upward under the push of the spiral groove 15. When the plug-in telescopic rod 9 moves upward all the time, it is separated from the upper end of the spiral groove 15. As the pressing depth of the pressure plate 14 increases, the corresponding gate plate 6 is continuously pushed to the upper end of the spiral groove 15, so that the water higher than the lower gate plate 6 can flow to the other side of the gate plate 6 in time, and the water level drops to below the lower gate plate 6, and the water discharge stops automatically. The gate plate 6 is controlled to move downward, and the dual-axis power box 12 is controlled to drive the two torsion columns 10 and the spiral groove 15 to rotate in the opposite direction. When the telescopic rod 9 is plugged in and coincides with the opening of the upper end of the spiral groove 15, the telescopic rod 9 enters the spiral groove 15 under the pressure of the gate plate 6, and drives the corresponding gate plate 6 to move downward. When the gate plate 6 drives the frame 8 downward to disengage from the pressure plate 14, the telescopic rod 9 is elastically connected and retracted into the frame 8, and the gate plate 6 continues to move downward under gravity to cooperate with the gate plate 6 below to re-seal the water surface.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
