Description

Technical Field

[0001] The utility model relates to the technical field of steel dams, and particularly relates to an inverted horizontal steel dam. Background Art

[0002] A steel dam, also known as a steel gate, is a new type of water conservancy project facility, which is widely used in river regulation, urban water ecological construction, farmland irrigation, hydropower generation and other fields. A steel dam usually consists of a steel structure framework, a bottom shaft, a gate panel, a hydraulic hoisting system, etc. It can stay at any angle and realize water retaining at any height, and is suitable for working conditions with a relatively wide gate opening and a relatively small water level difference. The steel dam gate can stand upright to store water and lie down to discharge flood and waterlogging. By appropriately opening to adjust the water level, it can also pass water over the top of the gate to form an artificial waterfall landscape effect.

[0003] The Chinese utility model patent with the publication number of CN221461125U discloses a steel dam gate with a flood discharge flap, which includes a gate and a mounting seat.

However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0030] Embodiment:

[0031] See Figures 1 - 7 , this embodiment provides an inverted horizontal steel dam, which includes a dam body 1, a gate 2, a hinge shaft 3 and a driving mechanism 4. An overflow trough 11 is arranged on the dam body 1. One end of the gate 2 is hinged in the overflow trough 11 through the hinge shaft 3. The hinge shaft 3 is fixedly connected to the lower end of the gate 2. The driving mechanism 4 is arranged on one side of the overflow trough 11. The hinge shaft 3 passes through the dam body 1 from one side of the overflow trough 11 and is connected to the driving mechanism 4; the driving mechanism 4 includes a rocker arm 41 and a first driving member 42. One end of the rocker arm 41 is fixedly connected to the hinge shaft 3, the other end of the rocker arm 41 is hinged to the first end of the first driving member 42, and the second end of the first driving member 42 is hinged to the dam body 1.

[0032] Specifically, the gate 2 is rotatably connected to the overflow trough 11 of the dam body 1 through the hinge shaft 3. Bearings and seals are arranged at the hinge between the hinge shaft 3 and the dam body 1. The friction between the gate 2 and the dam body 1 is reduced through the bearings. Through the arrangement of the seals, water in the overflow trough 11 is prevented from entering the bearings to erode the bearings, and at the same time, water in the overflow trough 11 is prevented from flowing out through the gap between the hinge shaft 3 and the dam body 1 to cause water leakage.

[0033] It can be understood that by driving the rocker arm 41 to rotate by the first driving member 42, the hinge shaft 3 and the gate 2 are further driven to rotate, so as to realize the adjustment of the angle of the gate 2. During the adjustment process, the first driving mechanism 4 and the rocker arm 41 are always located on one side of the overflow trough 11. When the water blocked by the gate 2 overflows from the top of the gate 2, the flowing water is separated from the first driving mechanism 4 and the rocker arm 41 by the dam body 1 and will not damage the first driving mechanism 4 and the rocker arm 41. Therefore, the service life of the first driving mechanism 4 and the rocker arm 41 can be improved.

[0034] It should be noted that in this embodiment, the first driving member 42 is a hydraulic cylinder. The cylinder end of the hydraulic cylinder is hinged to the dam body 1, and the piston rod end of the hydraulic cylinder is hinged to the rocker arm 41. By the telescopic movement of the hydraulic cylinder, the rocker arm 41 is pushed to rotate, thereby controlling the rotation of the hinge shaft 3 and the gate 2, and realizing the control of the angle of the gate 2. In other embodiments of the present application, the first driving member 42 may also be a linear driving mechanism or component such as an electric push rod or a cylinder.

[0035] Preferably, it further includes a first water stop member 5 and a second water stop member 6. Two first water stop members 5 are provided, and the two first water stop members 5 are respectively arranged on both sides of the gate 2. The second water stop member 6 is arranged at the bottom of the water passing trough 11. The first end of the first water stop member 5 is connected to the side of the gate 2, and the second end of the first water stop member 5 abuts against the inner side wall of the water passing trough 11. The first end of the second water stop member 6 is connected to the dam body 1, and the second end of the second water stop member 6 abuts against the hinge shaft 3.

[0036] It can be understood that the first water stop member 5 seals between the side wall of the gate 2 and the inner side wall of the water passing trough 11, and the second water stop member 6 seals between the hinge shaft 3 at the bottom of the gate 2 and the bottom wall of the water passing trough 11, thereby preventing water from leaking through the gap between the gate 2 and the inner wall of the water passing trough 11.

[0037] Preferably, it further includes a locking mechanism 7. The locking mechanism 7 includes a lock seat 71, a lock pin 72 and a second driving and positioning member 73. The lock seat 71 is arranged in an arc shape. Both ends of the arc-shaped lock seat 71 are fixedly connected to the dam body 1. A lock hole 711 is arranged on the arc-shaped lock seat 71 along the vertical direction of the rocker arm 41. The second driving and positioning member 73 is arranged on the lock seat 71. The lock pin 72 is connected to the output end of the second driving and positioning member 73. The second driving and positioning member 73 is used to drive the lock pin 72 to penetrate into or out of the lock hole 711.

[0038] It can be understood that when it is necessary to drive the gate 2 to rotate and position, the rocker arm 41 is driven to rotate by the first driving member 42, thereby driving the hinge shaft 3 and the gate 2 to rotate. When the rocker arm 41 rotates to a predetermined position, the second driving and positioning member 73 drives the lock pin 72 to insert into the corresponding lock hole 711, thereby limiting the positions of the rocker arm 41, the hinge shaft 3 and the gate 2, and positioning the gate 2, the rocker arm 41 and the hinge shaft 3 at the set position.

[0039] It should be noted that in this embodiment, the second driving and positioning member 73 is a hydraulic cylinder. The cylinder body end of the hydraulic cylinder is detachably connected to the rocker arm 41 by bolts, and a locking pin 72 is coaxially and fixedly connected to the piston rod end of the hydraulic cylinder. When the rocker arm 41 rotates to a set angle, the locking pin 72 is driven by the hydraulic cylinder to move along the axis direction of the hydraulic cylinder, so that the locking pin 72 is inserted into the corresponding locking hole 711 on the locking seat 71, and the locking pin 72 is positioned by the hydraulic cylinder. At this time, the position of the rocker arm 41 is limited and cannot rotate continuously, thus realizing the locking of the rocker arm 41. In other embodiments of the present application, the second driving and positioning member 73 may also be a linear driving mechanism or component such as an electric push rod or a cylinder.

[0040] Preferably, a plurality of locking holes 711 are arranged, and the plurality of locking holes 711 are arranged at intervals on the trajectory of the locking pin 72 swinging with the rocker arm 41.

[0041] It can be understood that by arranging a plurality of locking holes 711 on the locking seat 71, the plurality of locking holes 711 correspond to different opening angles of the gate 2. Therefore, when it is necessary to adjust the gate 2 to a set angle, the rocker arm 41 and the gate 2 are driven by the first driving member 42 to rotate to the set position, and the locking pin 72 is driven by the second driving and positioning member 73 to be inserted into the corresponding locking hole 711 to complete the adjustment of the angle of the gate 2.

[0042] Preferably, the first water stop member 5 includes a water stop lip strip 51 and a fastener 52. Two water stop lip strips 51 are arranged, and the two water stop lip strips 51 are symmetrically arranged along the plane where the gate 2 is located, and the two water stop lip strips 51 are fastened to the gate 2 by the fastener 52.

[0043] It can be understood that the water stop lip strip 51 seals between the gate 2 and the side wall of the water passing trough 11 to prevent water leakage. By symmetrically arranging the water stop lip strip 51, two-way water stop is realized.

[0044] Furthermore, the first water stop member 5 further includes two pressing plates 53. The two pressing plates 53 are respectively arranged on the sides of the two water stop lip strips 51 away from the gate 2, and the pressing plates 53 are pressed on the water stop lip strips 51 by the fastener 52.

[0045] It can be understood that the water stop lip strip 51 is often made of flexible materials such as rubber, silicone, polyurethane, etc. When directly fixed with bolts, the water stop lip strip 51 between the two bolts is not pressed by the bolts, resulting in poor water stop effect of the water stop lip strip 51 between the two bolts. After arranging the pressing plates 53, the pressing plates 53 are made of rigid materials such as iron plates. By pressing the iron plates with bolts, the water stop lip strip 51 between the two bolts is pressed by the pressing plates 53, so that any position of the water stop lip strip 51 is pressed, and the water stop effect of the water stop lip strip 51 is better.

[0046] Preferably, it further includes a support base 8, the support base 8 is fixedly connected in the water overflow tank 11, and one end of the support base 8 is supported and arranged in the middle of the hinge shaft 3.

[0047] It can be understood that when the length of the hinge shaft 3 is relatively long, under the pressure of the blocked water, the hinge shaft 3 and the steel door will bend and deform towards one side. On the one hand, after the bending deformation, gaps are likely to appear below the gate 2 and the hinge shaft 3, resulting in water leakage. On the other hand, when the span of the hinge shaft 3 and the gate 2 is relatively large, the hinge shaft 3 and the gate 2 may break and be damaged under the action of water pressure. By arranging the support base 8 on one side of the gate 2 to support the hinge shaft 3 and the gate 2, the deformation of the hinge shaft 3 and the gate 2 is prevented, water leakage is prevented, and the damage of the hinge shaft 3 and the gate 2 is prevented.

[0048] Furthermore, the support base 8 is provided with a wear-resistant pad 81, the wear-resistant pad 81 is arranged in an arc shape, and the wear-resistant pad 81 is detachably connected to the support base 8, and the wear-resistant pad 81 is arranged between the support base 8 and the hinge shaft 3.

[0049] It can be understood that through the arrangement of the wear-resistant pad 81, when the hinge shaft 3 rotates relative to the support base 8, the hinge shaft 3 and the wear-resistant pad 81 rub against each other. The wear-resistant pad 81 is made of a material with a relatively small friction coefficient and good wear resistance, such as polytetrafluoroethylene, which reduces the frictional resistance during the rotation of the hinge shaft 3 and improves the service life of the support base 8 and the hinge shaft 3. When the wear-resistant pad 81 is worn, it can be replaced in time.

[0050] Furthermore, the gate 2 is provided with a relief hole 21, and the relief hole 21 is arranged corresponding to the support base 8.

[0051] It can be understood that through the setting of the relief hole 21, the gate 2 can be rotated to the horizontal, so that the gate 2 is completely opened. Through the arrangement of the relief hole 21, the rotation angle of the gate 2 is widened, the rotation angle of the gate 2 is larger, and the working range is wider.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
