Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, and specifically relates to a small water conservancy gate. Background Art

[0002] Small water conservancy gates are facilities used to control water flow in rivers, channels, lakes and other water bodies. They play an important role in agricultural irrigation, flood control and drainage, water resources management, ecological environment protection and other aspects.

[0003] However, in actual use, small hydraulic gates are set up to control water flow and water level, and the water flow is discharged or introduced by opening the gates. After the existing small hydraulic gates are opened, the river is generally used to drain the canal. However, the flow of the river will bring up the sediment at the bottom. Since the gates block it, it will cause sediment to accumulate at the gates, making it difficult to open the gates. The existing method will stir the gates to reduce a certain amount of pressure when opening the gates, but the effect is not ideal. For this reason, we propose a small hydraulic gate.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solutions in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of this utility, not all of the embodiments. Based on the embodiment of this utility, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility.

[0028] Example 1

[0029] See also Figure 1-6 , this utility provides a technical solution:

[0030] A small water conservancy gate includes a frame 1, a gate body 2 arranged in the frame 1, two side panels 4 arranged on the sides of the frame 1, and a fixing frame 3 arranged on the side panels 4. The gate also includes:

[0031] A movable rod 8 is movably arranged between the two side panels 4;

[0032] The fixed cylinder 9 is sleeved on the movable rod 8;

[0033] The arc-shaped blades 5 are arranged on the outer surface of the fixed cylinder 9, and a plurality of the arc-shaped blades 5 are provided to remove the sediment on the gate body 2;

[0034] The driving assembly 6 is arranged in the fixed frame 3 and is used to drive the moving rod 8 to move, so that the arc-shaped blade 5 is raised and lowered, and the arc-shaped blade 5 is rotated toward its own inner side during the lifting process. The arc-shaped blade 5 rotates inward, which can keep the soil as far away from the gate body 2 as possible and reduce its friction.

[0035] The driving assembly 6 includes a rotating column 64 movably arranged inside the fixed frame 3, a handwheel 61 is provided on the outer surface of the rotating column 64, a transmission wheel 62 is provided at the bottom end of the rotating column 64, two fixed plates 66 are provided on the top of the inner wall of the fixed frame 3, and a rotating rod 65 is movably provided inside the two fixed plates 66. The outer surface of the rotating rod 65 is sleeved with a driven wheel 63, and the driven wheel 63 and the transmission wheel 62 are engaged with each other. By rotating the handwheel 61, the rotating column 64 and the transmission wheel 62 can be driven to rotate, and the engagement of the transmission wheel 62 with the transmission wheel 62 can drive the rotating rod 65 to rotate.

[0036] A second bevel gear 69 is provided at both ends of the rotating rod 65, and two straight rods 67 are movably provided on the inner wall of the fixing frame 3. The outer surfaces of the two straight rods 67 are sleeved with a first bevel gear 68, and the two second bevel gears 69 are movably provided on the outer surfaces of the corresponding first bevel gears 68. The set second bevel gears 69 and the first bevel gears 68 can change the rotation direction, thereby converting the horizontal direction into the vertical direction, thereby driving the straight rod 67 to rotate.

[0037] The interior of the side panel 4 is provided with a slide groove 612, and the bottom end of the straight rod 67 passes through the top of the side panel 4 and is movably set inside the slide groove 612. The bottom end of the straight rod 67 is provided with a threaded rod 610, and the bottom end of the threaded rod 610 is movably set at the bottom of the inner wall of the slide groove 612. The outer surface of the threaded rod 610 is threadedly connected to a slider 611, and the slider 611 is movably set on the inner wall of the slide groove 612. The side of the slider 611 is provided with a cleaning component 7 for rotating during the lifting process of the curved blade 5. The threaded rod 610 can drive the slider 611 threaded on the outer surface to rise and fall on the inner wall of the slide groove 612.

[0038] The cleaning assembly 7 includes a connecting rod 73 arranged on the adjacent side of the two sliders 611, and the outer surfaces of the two connecting rods 73 are sleeved with circular gears 72. The outer surfaces of the two connecting rods 73 are sleeved with connecting tubes 74. The adjacent ends of the two connecting tubes 74 are arranged at the two ends of the moving rod 8. The separated inner wall sides of the two sliding grooves 612 are provided with racks 71. The two racks 71 are movably arranged on the outer surfaces of the corresponding circular gears 72. The two racks 71 are at different positions of the two same circular gears 72, and the two can rotate in different directions during the lifting process.

[0039] The outer surfaces of the two connecting rods 73 are both sleeved with ratchets 76 in opposite directions, and the outer surfaces of the two ratchets 76 are both movably provided with pawls 77. The interiors of the two pawls 77 are both movably provided with guide pillars 78. The end faces of the two guide pillars 78 are respectively movably provided on the end faces of the corresponding connecting cylinders 74. The outer surfaces of the two guide pillars 78 are both sleeved with torsion springs 75. Due to the rotation of the two gears in different directions, the corresponding ratchet wheels 76 are driven to rotate. Due to the restriction of the pawls 77, the movable rod 8 can be driven to rotate through the connecting cylinder 74 only during the process of lifting or lowering, so that the arc-shaped blades 5 can rotate in the same direction when lifting.

[0040] When using this device, to open the gate body 2, you first need to turn the handwheel 61 to drive the rotating column 64 to rotate, and the rotating column 64 drives the transmission wheel 62 set at the bottom to rotate, and the transmission wheel 62 will drive the driven wheel 63 engaged on the outer surface to rotate, so that the driven wheel 63 drives the internal rotating rod 65 to rotate, and the rotating rod 65 drives the second bevel gear 69 on the two end sides to rotate, and the two second bevel gears 69 respectively drive the corresponding first bevel gear 68 to rotate, and the first bevel gear 68 drives the internal straight rod 67 to rotate, and the straight rod 67 drives the threaded rod 610 set at the bottom to rotate inside the slide groove 612, so that the threaded rod 610 drives the slider 611 threaded on the outer surface to descend, and the slider 611 drives the connecting rod 73 set on the side to move, and the connecting rod 73 drives the circular gear 72 set on the outer surface to rotate. There is a rack 71 engaged on the outer surface of the circular gear 72, so it can drive the circular gear 72 to rotate. When the gear 72 rotates, the circular gear 72 can drive the connecting rod 73 to rotate on the side of the slider 611. The rotation of the connecting rod 73 drives the ratchet 76 to rotate. The ratchet 76 drives the guide post 78 to rotate. The guide post 78 drives the connecting cylinder 74 set on the end surface to rotate. For this reason, the connecting cylinder 74 can drive the moving rod 8 set on the end surface to rotate, and can drive the fixed cylinder 9 to rotate through the moving rod 8. For this reason, the fixed cylinder 9 can drive the multiple curved blades 5 set on the outer surface to rotate inward, removing multiple dirt on the side of the gate body 2. When the ratchet 76 at one end of the moving rod 8 rotates, the ratchet 76 at the other end of the moving rod 8 will also rotate, but because the guide post 78 movable on its outer surface cannot be stuck in the ratchet 76, it cannot drive the moving rod 8 to rotate. However, when moving in the opposite direction, the states of the ratchet 76 and the pawl 77 at both ends of the moving rod 8 will change relatively, and the curved blades 5 can be driven to rotate inward when it can be raised or lowered.

[0041] Example 2

[0042] See also Figure 7 , this utility provides a technical solution:

[0043] Different from Example 1, the outer surface of the slider 611 is provided with multiple circular grooves 10, and the interior of the multiple circular grooves 10 is movably provided with balls 11. The outer surfaces of the multiple balls 11 are movably provided on the inner walls of the corresponding slide grooves 612. When the slider 611 is moved, the provided balls 11 reduce the friction force of the slider 611 on the inside of the slide groove 612, thereby reducing the force of rotating the handwheel 61.
