TECHNICAL FIELD
[0001] The utility model relates to water conservancy facilities technical field especially is related to a water gate pier protection structure. BACKGROUND
[0002] The water gate is built in the river, channel and reservoir, lake bank, has the low water head hydraulic structure of water retaining and water releasing function. Closing gate can block flood, tide or raise the upstream water level to satisfy irrigation, power generation, navigation, water product, environmental protection, industrial and domestic water needs etc.; open gate, can release flood, waterlogging, abandon water or waste water, also can supply water to downstream river or channel.
[0003] In the process of opening the gate to release water, because the water gate pier is soaked in water for a long time, and the water will scour the water gate pier for a long time, which will cause the concrete on the surface of the water gate pier to fall off, and there may be some danger in the long run. UTILITY MODEL CONTENTS
[0004] The utility model discloses a water gate pier protection structure to solve the above-mentioned prior art problem, which is realized by the following technical scheme:
[0005] A water gate pier protection structure, comprising a middle gate pier and a side gate pier, the middle gate pier is provided with a gate slot on both sides, the side gate pier is also provided with a gate slot on the side close to the middle gate pier, the middle gate pier is arranged between the side gate piers, an arc-shaped long plate is fixedly installed on the upstream side of the middle gate pier, the arc-shaped long plate is a vertical long plate provided with an arc-shaped opening on the front side, a half-arc plate is fixedly installed on the front side of the side gate pier, the half-arc plate is a vertical long plate provided with a half-arc opening on the front side, and the half-arc openings on both sides are oppositely arranged.
[0006] The utility model is further provided as follows: vertical first stepped walls are fixedly arranged on both sides of the arc-shaped long plate, the side wall of the first stepped wall in the water flow direction is inclined, vertical second stepped walls are fixedly arranged on the side wall of the side gate pier close to the middle gate pier, the front side of the second stepped wall is fixed to the side wall of the half-arc plate, and the side wall of the second stepped wall in the water flow direction is inclined.
[0007] The utility model is further provided as follows: the first stepped wall and the second stepped wall are arranged on the front side of the gate slot.
[0008] The utility model is further provided as follows: third stepped walls are fixedly arranged on both sides of the middle gate pier and the side of the side gate pier close to the middle gate pier.
[0009] The utility model is further provided as follows: the third stepped wall is arranged on the back side of the gate slot, and the back side of the third stepped wall is flush with the back side walls of the middle gate pier and the side gate pier.
[0010] In summary, the utility model has the beneficial technical effects that:
[0011] By setting up an arc-shaped long plate, when the upstream water flows downward, it is buffered by flowing into the arc-shaped long plate. Then, the water inside the arc-shaped long plate flows back and collides with the water flowing down again, creating an impact. This achieves the effect of reducing the impact force of the water flow. By setting up a semi-arc plate, the water flow is buffered as it flows down, allowing the water to flow inward along the semi-arc opening, thereby reducing the scouring force of the water flow on the gate pier and preventing the concrete on the gate pier surface from falling off, thus preventing subsequent dangers in advance. By setting up a first-step wall and a second-step wall, the water flow speed is slowed down, thereby reducing the scouring force of the water flow on the side wall of the gate pier. By setting up a third-step wall, the water flow rate of the water remaining in front of the gate slot is slowed down at the moment the sluice gate is opened. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.
[0016] Example
[0017] like Figs. 1-2 As shown, this utility model discloses a sluice gate pier protection structure, including a central pier 1 and side piers 2. The central pier 1 has gate slots 101 on both sides, and the side piers 2 also have gate slots 101 on the side closest to the central pier 1. The central pier 1 is located between the side piers 2. An arc-shaped long plate 3 is fixedly installed on the upstream side of the central pier. The arc-shaped long plate 3 is a vertical long plate with an arc-shaped opening 301 on its front side. A semi-arc plate 4 is fixedly installed on the front side of the side piers 2. The semi-arc plate 4 is a vertical long plate with a semi-arc opening 401 on its front side, and the semi-arc openings 401 on both sides are arranged opposite each other.
[0018] Both sides of the arc-shaped long plate 3 are fixedly provided with vertical first step walls 5. The side wall of the first step wall 5 in the direction of water flow is inclined. The side wall of the side gate pier 2 near the middle gate pier 1 is fixedly provided with a vertical second step wall 6. The front side of the second step wall 6 is fixed to the side wall of the semi-arc plate 4. The side wall of the second step wall 6 in the direction of water flow is inclined.
[0019] The first stepped wall 5 and the second stepped wall 6 are arranged at the front side of the gate slot 101.
[0020] The third stepped wall 7 is arranged at the rear side of the gate slot 101, and the rear side of the third stepped wall 7 is flush with the rear side walls of the middle gate pier 1 and the side gate pier 2.
[0021] The third stepped wall 7 is arranged at the rear side of the gate slot 101, and the rear side of the third stepped wall 7 is flush with the rear side walls of the middle gate pier 1 and the side gate pier 2.
