Implementation

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is combined with the drawings and embodiments. The following is combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solution in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, a steel gate structure for a water conservancy project includes a support frame 1, the outer surface of the support frame 1 is provided with two symmetrical first slide grooves 2, the outer surface of the support frame 1 is provided with two symmetrical second slide grooves 3, the inner wall of the first slide groove 2 is slidably connected with a gate body 4, the inner wall of the gate body 4 is provided with a card slot 5, and the outer surface of the support frame 1 is provided with a limiting mechanism 6.

[0021] The limiting mechanism 6 includes a bracket 601 , the outer surface of the bracket 601 is fixedly connected to the outer surface of the support frame 1 , the inner wall of the bracket 601 is rotatably connected to a rotating shaft 602 , and the outer surface of the rotating shaft 602 is fixedly connected to a rotating column 603 .

[0022] In this embodiment, the surface of the rotating column 603 is provided with anti-skid grooves to prevent the hand from slipping when the rotating column 603 is rotated.

[0023] Two symmetrical threaded rods 604 are fixedly connected to both ends of the rotating shaft 602 , and the outer surfaces of the threaded rods 604 are rotatably connected to the inner wall of the bracket 601 . The ends of the two threaded rods 604 that are away from each other are fixedly connected to a blocking plate 605 .

[0024] In this embodiment, the blocking plate 605 can prevent the moving plate 606 from sliding off the surface of the threaded rod 604 .

[0025] The outer surfaces of the two threaded rods 604 are both threadedly connected with a moving plate 606 .

[0026] The rotating column 603 is manually rotated, and the rotating column 603 drives the rotating shaft 602 to rotate. When the rotating shaft 602 rotates, the threaded rod 604 is also rotated, thereby driving the moving plates 606 threadedly connected on both sides to move toward the middle.

[0027] The side surfaces of the two movable plates 606 that are close to each other are fixedly connected to the limiting rods 607 , and the outer surfaces of the limiting rods 607 are slidably connected to the inner wall of the bracket 601 .

[0028] In this embodiment, the movement of the movable plate 606 is limited by the combination of the limiting rod 607 and the bracket 601, so that the movable plate 606 cannot rotate along with the threaded rod 604, thereby making the movable plate 606 move stably.

[0029] An inserting block 608 is fixedly connected to a side surface of the two movable plates 606 that are close to each other, and an outer surface of the inserting block 608 is inserted into the inner wall of the card slot 5 .

[0030] When the movable plate 606 moves to the limit position toward the gate body 4 , the insert block 608 can be inserted into the inner wall of the slot 5 , thereby limiting and fixing the gate body 4 .

[0031] Two symmetrical rotating motors 7 are fixedly connected to the upper surface of the support frame 1 , and gears 8 are fixedly connected to the output ends of the two rotating motors 7 . Two symmetrical gear rods 9 are fixedly connected to the outer surface of the gate body 4 .

[0032] The outer surface of the gear rod 9 is slidably connected to the inner wall of the support frame 1 , and the gear rod 9 is meshed with the gear 8 .

[0033] The rotating motors 7 on both sides are started to drive the gears 8 to rotate, thereby driving the meshing gear rods 9 and the gate body 4 to move upward, and under the guidance of the first slide groove 2, the gate body 4 can be moved up and down in a directional manner.

[0034] The inner wall of the second chute 3 is provided with a cleaning mechanism 10 .

[0035] The cleaning mechanism 10 includes a fixed rod 1001 , the outer surface of which is slidably connected to the inner wall of the second slide groove 3 , the outer surface of which is fixedly connected to two frames 1002 , and the outer surface of the frame 1002 is fixedly connected to the outer surface of the gate body 4 .

[0036] When the gate body 4 moves upward, it can drive the frame 1002 and the fixing rod 1001 to move. When it moves upward, the garbage blocked by the surface of the filter screen 1003 can be collected into the collecting bucket 1005, which is convenient for the staff to clean.

[0037] The inner wall of the fixing rod 1001 is fixedly connected with a filter screen 1003 , the outer surface of the fixing rod 1001 is fixedly connected with two fixing blocks 1004 , and a collecting bucket 1005 is fixedly connected to a side of the two fixing blocks 1004 close to each other.

[0038] Filter holes are provided on the surface of the collecting bucket 1005, which can discharge the water inside the collecting bucket 1005 while collecting the garbage, thereby clearing out the garbage as a whole.

[0039] Working principle: When using this embodiment, first, start the rotating motors 7 on both sides to drive the gears 8 to rotate, thereby driving the meshing gear rods 9 and the gate body 4 to move upward, and under the guidance of the first slide 2, the gate body 4 can be directional and lifted. Then, while the gate body 4 moves upward, it can drive the frame 1002 and the fixing rod 1001 to move. While moving upward, the garbage blocked by the surface of the filter screen 1003 can be collected into the collection bucket 1005, which is convenient for the staff to clean. Finally, when the gate body 4 rises to the top, the rotary knob is manually rotated. The movable column 603 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the threaded rod 604 to rotate at the same time, thereby driving the threaded movable plate 606 to move. At this time, the movement of the movable plate 606 is limited by the combination of the limiting rod 607 and the bracket 601, so that the movable plate 606 cannot rotate with the threaded rod 604, thereby making the movable plate 606 move stably. After the movable plate 606 moves to the extreme position toward the gate body 4, the insert block 608 can be inserted into the inner wall of the slot 5, thereby limiting and fixing the gate body 4.
